Full textAbstract:
Automotive service industry currently holds an important role in helping to increase customer satisfaction. Various strategies are carried out to win the competition for increasing customer satisfaction. Quality service combined with the right instruments can be used to increase customer satisfaction and loyalty. Customer satisfaction is the key to success in the manufacturing and service industries. Service quality is an important attribute and it is a key factor in service industries. Improving lead time service in automotive Toyota dealer service industries is the focus of this research. Value Stream Mapping succeeded in identifying problems that were happening as an impact of waiting for services, washing processes, and length of service processes. The DMAIC (Define, Measure, Analyze, Improve and Control) method assisted by tools of quality successfully analyzed and gave recommended corrective actions to reduce the lead time of Express Maintenance Service from 120.06 minutes to 64.00 minutes or improved 53% per service cycle, and succeeded in increasing the capability of the service process from 1.96 sigma to 3.80 sigma. Quality of service can be improved to get customer satisfaction, increase company profitability, and increase the competitiveness of companies in maintaining the sustainability of the industry in the future.

Full textAbstract:
From 1877 to 1929 the Bell System extended its qualityassurance capabilities, a step that was critical to the company's ability to certify the reliability of its equipment and apparatus and to provide economical service. Learning in this context involved the gradual development of an organizational structure for coordinating and controlling quality-assurance activities at both the staff and line levels and between the corporate elements of the Bell System. Over the course of the initiative, innovative methods of analysis emerged that provided useful new insights into the manufacturing process. The company's adaptation of probability theory, for example, enabled it to launch a comprehensive inspection regime, which became known as “statistical quality control” (SQC). Based on this new approach, Bell succeeded in broadening its manufacturing knowledge, quantifying definitions of quality, reducing costs and risk, thus assuming the more reliable operation of its vast telephone network. Eventually this upgrading of learning led to the formation of a new profession of quality engineering, which found adherents across many industries in the United States and abroad.

Full textAbstract:
Purpose The purpose of this paper is to understand the antecedents of fanaticism through the lens of attribution theory and “norm of reciprocity”. It is proposed that consumers will reward firms with high perceived effort, including both general and specific effort by increasing their loyalty and becoming a fan of the company. Design/methodology/approach The data are collected in a high-tech services industry, mobile phone services. A paper-based survey using mall intercept technique was employed in this study. The sampling design was a combination of convenience sampling (any adult who happened to be at a given location on a given day and time) and system probability sampling (every fifth adult who passed the data collection point was approached and asked to participate in the study). The final sample size is 600. Findings The antecedents of fanaticism are identified as both firm’s general effort (i.e. service quality and innovativeness) and specific effort (i.e. perceived reciprocity). In addition, perceived regulatory control moderated the relationship between innovativeness, part of firm’s general effort and customer fanaticism. To be more specific, perceived regulatory control increased the effect of perceived innovativeness on fanatical loyalty. Originality/value The introduction of the role of perceived regulatory control in the interactions between firms and customers has not been adopted in previous research and can contribute a new body of knowledge to the current literature. This research has implications for service providers, especially in high-tech industries.

Full textAbstract:
Different production arrangements have been experienced in several economic fields. It is possible to observe integration cycles, when a company becomes responsible for consecutive stages in the production chain of goods and services. This process, known as vertical integration, generates many implications that have been analyzed by studies about operational management, transaction costs economics, competition and anti-trust regulation. Focused on the healthcare industry, this research aims to analyze the managerial perception about vertical integration in this field, aiming to gain insights about the motivations and implications of this process, not sufficiently exploited by the specialized literature. Using a qualitative approach, interviewees were asked to rank possible vertical integration benefits. It was noticed that the control of production costs and the optimization of services' quality were the main benefits of this process. Obtained results reinforce some perceptions gained at studies conducted among north american companies; however, some differences were observed, which are characteristic of the analyzed context.

Full textAbstract:
Over half of mother-to-child HIV transmission (MTCT) occurs postdelivery. Keeping mother–infant pairs in care remains challenging. Health workers in 3 countries used quality improvement (QI) approaches to improve data systems, mother–infant retention, and facility-based care delivery. The number and proportion of infants with known HIV status at time of discharge from early infant diagnosis programs increased in Tanzania and Uganda. We analyzed data using statistical process control charts. Mother-to-child HIV transmission did not decrease in 15 Kenyan sites, decreased from 12.7% to 3.8% in 28 Tanzanian sites, and decreased from 17.2% to 1.5% in 10 Ugandan sites with baseline data. This improvement is likely due to the combination of option B+, service delivery improvements, and retention through QI approaches. Reaching the global MTCT elimination target and maximizing infant survival will require health systems to support mother–infant pairs to remain in care and support health workers to deliver care. Quality improvement approaches can support these changes.

INTRODUCTION. As highlighted in the 2018 Uganda Education Response Plan, reading levels in refugee host communities are way below the national average. Since the 2018 National Assessment of Progress in Education report highlighted some challenging areas to the in-service teachers, a possible explanation for the persistent poor performance of learners in reading may reside with the finding that many educators themselves lack an understanding of the linguistic construct. Therefore, an informed training for teachers in primary schools was implemented to help them foster learners’ reading skills. The purpose of this paper is consequently to analyse whether learners whose teachers participated in the evidence-based intervention have better reading skills than those whose teachers did not participate in the intervention. METHOD. To achieve this, a quasi-experimental pre-program/post-program design, involving 2 schools, 24 teachers (12 per school), and 297 learners (157 from treatment and 140 from control) from Palabek (Uganda) refugee settlement was adopted. FINDINGS. The findings show that the reading skills of learners whose teachers participated in the intervention significantly improved as compared to their counterparts. Particularly, learners’ reading skills significantly improved in the areas of letter sound knowledge, segmenting knowledge, and nonword decoding, and slightly in oral passage reading and comprehension, and English vocabulary. DISCUSSION. This study therefore supported the hypothesis linked to the Peter Effect - one cannot be expected to give what they do not possess and raised a need for the Ministry of Education and Sports to mandate sufficient and informed training of teachers.

Full textAbstract:
Competitiveness of a company has been based on the ability of locating and solving the com-mercial troubles more quickly and effectively than other competitors. For small and medium-sized enterprises (SMEs), it is necessary to expand the boundaries of the traditional organizations and promote across-domain knowledge in different industries. Thus, the opportunities of industrial in-novation can be increased, and the bright future of the industry can also be confirmed. In Taiwan, there are numerous SMEs in various industries. Conducting and researching in resource conservation service innovation technology and transforming system are deemed to be important for modern enterprises. This research was aimed at building a service-oriented system for saving the energy and reducing discharges to perform a new mechanism of resource conservation services for SMEs. The project “Construction of System Dynamics Model on Service Strategy and Resource Management” was aimed to assist “Wai Cheong Electrical Engineering Co., Ltd.”at Chung Hsing Industry Park in Miaoli. The System Dynamics was primarily introduced into this project for per-formance analysis, so that the proposed performance evaluation model could be formulated. With the performance evaluation on the indicators, the overall performance structure was clarified as well. After the reliability analysis of the proposed model was verified, the data provided dynamic results on demand forecasting, quality control, and marketing management for decision making. Then, the effectiveness would be practically adjusted for different quality levels to predict the actual need. It’s the essential way to recognize the cost variation and observe other parameters of the marketing strategy. The strategy was effective to achieve the goals of removing the strategic planning con-straints and reducing resource consumption caused by improper decisions. In conclusion, the con-struction of this model would enhance the opportunity to succeed and achieve in the company’s op-timum profits when confronting the current dynamic and competitive market environment.

Abstract Objectives: To describe the pattern of AIDS-associated cancers among patients referred to a palliative care service in the absence of HAART therapy. Design: A systematic review of patient records as part of an ongoing quality assurance project. Setting: A primary palliative care service centre for cancer and/or AIDS patients in Kampala district, Uganda. Participants: All patient charts from 1994 to 2002 that met inclusion criteria (positive HIV test, or an AIDS diagnosing condition and AIDS-associated cancer) were selected. Results – 657 out of 3,706 (17.7%) patients met inclusion criteria. Fifty-two percent were female and the median age was 33 years. Thirty-nine percent were referred for pain and symptom control, 51.9% for pain control only, 7.0% for symptom control only; and 2.3% were referred for other reasons. Ninety-six percent were in pain and 95% of these had moderate-to-severe pain. Kaposi’s sarcoma was the most common AIDS associated malignancy, accounting for 73.2% of cases followed by invasive cancer of the cervix (15.1%), non-Hodgkin’s lymphoma (6.4%) and squamous cell carcinoma of the conjunctiva (1.8%). 83.4% had their pain well controlled at the time of death. Conclusions: The number and proportion of patients with Kaposi’s sarcoma declined over the study period. Pain control was achievable in most patients despite restrained resources.

Quality of care plays an important role in the status of tuberculosis (TB) control, by influencing timely diagnosis, treatment adherence, and treatment completion. In this study, we aimed at establishing the quality of TB service care in Kamuli district health care centres using Donabedian structure, process, and outcomes model of health care. A cross-sectional study was conducted in 8 health care facilities, among 20 health care workers and 392 patients. Data was obtained using face-to-face interviews, an observation guide, a check list, and record review of the TB unit and laboratory registers. Data entry and analysis were done using EPI INFO 2008 and STATA 10 versions, respectively. A high number 150 (87.21%) of TB patients were not aware of all the signs to stop TB medication, and 100 (25.51%) patients received laboratory results after a period of 3–5 working days. The major challenges faced by health workers were poor attitude of fellow health workers, patients defaulting treatment, and fear of being infected with TB. One of the worst performance indicators was low percentage of cure. Comprehensive strengthening of the health system focusing on quality of support supervisions, patient follow up, promoting infection control measures, and increasing health staffing levels at health facilities is crucial.

Full textAbstract:
Modern users are accustomed to always-accessible networks ready to serve all of their communication, entertainment, information, and other needs, at the touch of their devices. Spoiled with choices provided on the competitive markets, the risk of customer churn makes network and service providers sensitive to user Quality of Experience (QoE). Services that enable people to work and industries to function in these pandemic times, such as the telemeeting service, are becoming ever more critical, not just for the end-users but also for the providers. Nevertheless, the heterogeneity of end-users network environments and the uniqueness of the service (bidirectional video and audio transmissions and interactivity between the meeting peers) imposes specific QoE requirements. Hence, this paper focuses on understanding how different service quality degradations affect user perception and frustration with such impaired service. The impact of eight quality degradations was analyzed. Based on the conducted user study, we used the multiple regression analysis and developed three models capable of predicting user Level of Frustration (LoF) for the specific degradations that we have analyzed. The models work with the User Frustration Susceptibility Index (UFSI), which categorizes users into groups based on their tendency to become frustrated with the impaired service.

A relatively inexpensive and highly effective design for high precision chamber was developed but the control theory and optimized parameters were totally different from traditional methodologies. Among all kinds of quality programs, lean six sigma (LSS) is the most famous and widely-used method by manufacturing and service industries. The DMAIC (Define, Measure, Analyze, Improve and Control) methodology was used to figure out the key factors relative to high precision of relative humidity and improve the control parameters to meet the target. At the start, the baseline of Z bench was-0.24 and standard deviation was 1.62659. After lean six sigma project implemented, Z bench was up to 1.89 and standard deviation was down to 0.443986. This paper will address the critical process and analysis method for lean six sigma project, especially those for precise control of relative humidity.

Full textAbstract:
Health, safety, and environment risk assessment, based on company quality, health, safety, and environment commitments, constitutes a precondition in the definition of the strategy to be adopted by the maintenance service. The imperfections of the knowledge; the disputes over opinions among decision-makers; and the absence of health, safety, and environment equipment risk assessment integrated models hinder the assessment of risk acceptability. In this article, we propose a health, safety, and environment risk management approach for the equipment maintenance. This approach expands the scope of action relative to the overall equipment risk-level assessment. It is based, on one hand, on fuzzy logic and, on the other hand, on two methods of decision-making support: the method of converting verbal judgments into numerical values and the pair comparison of decision criteria. This approach allows the maintenance service to implement a health, safety, and environment risk control policy for the most critical equipment. Therefore, it allows to improve the staff and product safety and to protect the environment in accordance with the strategic objectives.

Full textAbstract:
Control charts serve as an effective tool for controlling and monitoring process quality in industries of production and service. The Shewhart chart is the first control chart that was used to detect large mean shifts in a process. Since then, to increase the Shewhart chart’s sensitivity, synthetic type control charts, such as synthetic control chart, side sensitive group runs (SSGR) control chart, have been proposed. SSGR chart ismore efficient compared to the Shewhart chart and synthetic chart,primarily due to the side sensitive feature in SSGR chart. Meanwhile, exponentially weighted moving average (EWMA) chart isoften used to detect small process changes. In practice, the evaluation of a control chart’s performance is vital. Nevertheless, the cost of implementing a control chart is an important factor that influences the choice of a control chart. The cost of repairs, sampling, nonconforming products from a failure in detecting out-of-control status, and investigating false alarms, can be significantly high. Therefore, the aim of this paper is to compare the implementation cost of synthetic, SSGR and EWMA charts, so that quality practitioners can identify the most cost-effective chart to implement. Here, the cost function was adopted to compute the implementation cost of the control chart. According to the findings, quality practitioners are recommended to adopt the SSGR chart,since it is more economical compared to the synthetic chart. However, the cost to implement anEWMA chart is higher than the synthetic and SSGR charts. In light of this, this study allows for quality practitioners to have a better idea on the selection of the control chart to implement, with respect to its cost.

Full textAbstract:
Purpose – The purpose of this paper is to establish the relationship between managerial competence, managerial risk-taking behaviour and financial service outreach of microfinance institutions (MFIs). Design/methodology/approach – In this cross-sectional and correlational study, the authors surveyed 52 branches of MFIs from a population of 60 branches of 20 MFIs in eastern Uganda. Two respondents, a branch manager and a senior loan officer, were the units of enquiry for each branch. The authors put forward and tested four hypotheses relating to the significance of the relationship between perceived managerial competence, risk-taking behaviour and financial service outreach using SPSS version 20. The authors established the hypothesized relationships using Pearson correlation coefficients and obtain a mediating effect of risk-taking behaviour using partial corrections and regression analysis. Findings – The results suggest positive and significant relationships between perceived managerial competence, risk-taking behaviour and financial service outreach. However, while the direct relationship between managerial competence and financial service outreach without the mediation effect of risk-taking behaviour of managers was found to be significant, its magnitude reduces when mediation of risk-taking behaviour is allowed. Thus the entire effect does not only go through managerial competence but majorly also, through risk-taking behaviour of managers. Research limitations/implications – This study did not control for environmental factors such as laws and regulations. As such the model may have been under fitted. Nevertheless, the study has introduced a clearer understanding that outreach performance in MFIs rests with competent managers in strategic positions operating in synergy with their risk-taking behaviour. The study informs policy makers that outreach performance of the MFIs depends on the quality of the competence managers have in addition to their risk-taking propensities. Practical implications – Efforts by the stakeholders to improve financial service outreach must be matched with appropriate competences and risk-taking behaviour of managers. Originality/value – The results contribute to extant literature by investigating two explanatory variables for financial service outreach and provide initial evidence of the mediating effect of intrinsic high risk-taking behaviour of managers. Results add to the conceptual improvement in risk-taking behaviour and lend considerable support for the behavioural perspective in the study of financial service outreach of MFIs.

Full textAbstract:
Purpose – The increasing prevalence of unconventional appearance attributes (e.g. tattoos, piercings, unnatural hair color, alternative clothing) is a concern among employers as these appearance attributes are often viewed negatively. Because much of the existing employee appearance research has been conducted in the USA, the purpose of this paper is to examine employee beliefs regarding the impact of unconventional employee appearance on customer perceptions of service quality in Mexico and Turkey. The authors also examine the impact of gender, age, and position level. Design/methodology/approach – The sample consisted of 295 white collar employees in various service industries in Turkey and Mexico. Respondents reported how they thought eight employee appearance factors (tattoos, facial piercings, unconventional hair color, unconventional hair styles, sweat pants, clothing with rips or tears, clothing that bears midriffs, belly-buttons, or cleavage, and uniforms) would affect customer perceptions of service quality. Findings – Employees in both Mexico and Turkey indicated that uniforms would have a positive impact on customer perceptions of service quality and all seven unconventional employee appearance attributes would have a negative impact. Significant differences for country, gender, age, and position level were also found. Research limitations/implications – Future research including a more diverse group of countries and cultures is needed. Future research should also attempt to control for differences in type of organization, organizational culture, and job type. Practical implications – Alternative fashion and appearance styles may be trendy but there are risks in how these might be perceived by customers and by colleagues at work. Originality/value – This study examines employee beliefs regarding the impact of a variety of unconventional employee appearance attributes on customers’ perceptions of service quality in Mexico and Turkey.

PurposeThe purpose of the study is to establish the mediating role of Perceived Service Quality on the relationship between Retail Atmospherics and Retail Store Patronage of Supermarkets in Emerging Economies using empirical evidence from Uganda.Design/methodology/approachThe study used a cross-sectional research design and quantitative approach to understand stand the structured reality of Retail Store Patronage of supermarkets in context of emerging economies. In the context of this study, the data were drawn from Uganda's supermarkets. A sample of 1,504 customers were selected from 136,270 customers. Data was collected from supermarket customers using closed ended questionnaire. Descriptive and inferential statistics were derived to describe the behavior of customers and draw conclusions on population using sample statistics. Correlation analysis was used to establish the degree of association between the variables. Hierarchical regression was applied to assess the unique contribution of each variable; control variables-income and age, predictor variables – Retail Atmospherics and Perceived Service Quality on dependent variable – Retail Store Patronage. Mediation was done following the four-step procedures of mediation of Baron and Kenny (1986).FindingsThe results revealed significant positive relationship between Retail Atmospherics, Perceived Service Quality and Retail Store Patronage, confirming the direct hypotheses. Perceived Service Quality partially mediated the relationship between Retail Atmospherics and Retail Store Patronage. The findings depict that Retail Store Patronage is influenced directly by Retail Atmospherics and indirectly through Perceived Service Quality as a mediating variable. However, in situations where the atmospherics is good but perceived service quality is poor, Retail Store Patronage may not be fully realized.Originality/valueThe study provides information that is relevant for filling the practical and theoretical gap in the Retail Store Patronage in Ugandan supermarkets. Previous research studies investigated patronage behavior of shoppers in single retail units yet there is paucity of research on patronage behavior across different retail formats in the world. This study can be generalized and have strategic implications to developing economies that seek to grow and sustain their businesses. It points to the gaps that are normally overlooked and could lead business failure. The focus of most previous studies were on developed economies more especially Europe and America. This study in particular focused on the role of perceived service quality in the relationship between retail atmospherics and customer retail store patronage in emerging economies like Uganda as a testing ground.

Full textAbstract:
Purpose – The purpose of this paper is to counter autocorrelation by designing the chart, using warning limits. Various optimal schemes of modified chart are proposed for various sample sizes (n) at levels of correlation (Φ) of 0.00, 0.475 and 0.95. These optimal schemes of modified chart are compared with the double sampling (DS) chart, suggested by Costa and Claro (2008). Design/methodology/approach – The performance of the chart is measured in terms of the average run length (ARL) that is the average number of samples before getting an out-of-control signal. Ultimately, due to the effect of autocorrelation among the data, the performance of the chart is suspected. The ARLs at various sets of parameters of the chart are computed by simulation, using MATLAB. The suggested optimal schemes are simpler schemes with limited number of parameters and smaller sample size (n=4) and this simplicity makes them very helpful in quality control. Findings – The suggested optimal schemes of modified chart are compared with the DS chart, suggested by Costa and Claro (2008). It is concluded that the modified chart outperforms the DS chart at various levels of correlation (Φ) and shifts in the process mean. The simplicity in the design of modified chart, makes it versatile for many industries. Research limitations/implications – Both the schemes are optimized by assuming the normal distribution. But this assumption may also be relaxed to design theses schemes for autocorrelated data. The optimal schemes for chart can be developed for variable sample size and for variable sampling intervals. The optimal schemes can also be explored for cumulative sum and exponentially weighted moving average charts. Practical implications – The correlation among the process outputs of any industry can be find out and corresponding to that level of correlation the suggested control chart parameters can be applied. The understandable and robust design of modified chart makes it usable for industrial quality control. Social implications – The rejection level of products in the industries can be reduced by designing the better control chart schemes which will also reduce the loss to the society, as suggested by Taguchi (1985). Originality/value – Although it is the extension of previous work but it can be applied to various manufacturing industries as well as service industries, where the data are positively correlated and normally distributed.

IntroductionSuboptimal quality of paediatric care has been reported in resource-limited settings, but little evidence exists on interventions to improve it in such settings. This study aimed at testing supportive supervision (SS) for improving health status of malnourished children, quality of case management, overall quality of care, and the absolute number of children enrolled in the nutritional services.MethodsThis was a cluster randomised trial conducted in Arua district. Six health centres (HCs) with the highest volume of work were randomised to either SS or no intervention. SS was delivered by to HCs staff (phase 1), and later extended to community health workers (CHWs) (phase 2). The primary outcome was the cure rate, measured at children level. Quality of case management was assessed by six pre-defined indicators. Quality of care was assessed using the national Nutrition Service Delivery Assessment (NSDA) tool. Access to care was estimated with the number of children accessing HC nutritional services.ResultsOverall, 737 children were enrolled. In the intervention arm, the cure rate (83.8% vs 44.9%, risk ratio (RR)=1.91, 95% CI: 1.56–2.34, p=0.001), quality of care as scored by NSDA (RR=1.57, 95% CI: 1.01–2.44, p=0.035) and correctness in complementary treatment (RR=1.52, 95% CI: 1.40–1.67, p=0.001) were significantly higher compared with control. With the extension of SS to CHWs (phase 2), there was a significant 38.6% more children accessing care in the intervention HCs (RR=1.26, 95% CI: 1.11–1.44, p=0.001) compared with control.ConclusionSS significantly improved the cure rate of malnourished children, and the overall quality of care, SS to CHWs significantly increased the crude number of children enrolled in the nutritional services. More studies should confirm these results, and evaluate the cost-effectiveness of SS.

Full textAbstract:
Multivariate statistical process control is the continuation and development of unitary statistical process control. Most multivariate statistical quality control charts are usually used (in manufacturing and service industries) to determine whether a process is performing as intended or if there are some unnatural causes of variation upon an overall statistics. Once the control chart detects out-of-control signals, one difficulty encountered with multivariate control charts is the interpretation of an out-of-control signal. That is, we have to determine whether one or more or a combination of variables is responsible for the abnormal signal. A novel approach for diagnosing the out-of-control signals in the multivariate process is described in this paper. The proposed methodology uses the optimized support vector machines (support vector machine classification based on genetic algorithm) to recognize set of subclasses of multivariate abnormal patters, identify the responsible variable(s) on the occurrence of abnormal pattern. Multiple sets of experiments are used to verify this model. The performance of the proposed approach demonstrates that this model can accurately classify the source(s) of out-of-control signal and even outperforms the conventional multivariate control scheme.

Full textAbstract:
PurposeThe purpose of this paper is to propose a model (structural equation modeling (SEM)) from the 16 identified just in time (JIT) elements useful for implementation of JIT in maintenance.Design/methodology/approachData were collected using questionnaires posted to 421 manufacturing industries and automotive service industries in India from which 133 usable responses were obtained. First, exploratory factor analysis (EFA) is carried out to identify the factor structure after that confirmatory factor analysis (CFA) is carried out to verify the factor structure of a set of identified JIT elements. CFA is conceded by an SEM statistical technique. In this paper, EFA is applied to extract the factors in JIT implementation by the statistical package for social sciences (SPSS 24) software and confirming these factors by CFA through analysis of moment structures (AMOS 18) software.FindingsOut of 18 identified JIT elements through literature and expert opinion only 16 JIT elements are selected for the study, two JIT elements removed due to the low value of correlation item-total correlation (CITC). Three factors extracted through EFA, which affects the benefits of JIT implementation in maintenance in quality improvement, production improvement and process control. SEM using AMOS 18.0 was used to perform the first-order three-factor structure (quality improvement, production improvement and process control) of the JIT implementation in maintenance.Originality/valueThe results will be useful for maintenance managers and maintenance professionals to understand the process of implementation of JIT in maintenance and to gain benefits after the implementation of JIT in maintenance in their respective organization.

Full textAbstract:
Mobile Augmented Reality (AR), which mixes the real world and the virtual world on hand-held devices, is a growing area of the manufacturing industry. Since mobile AR can be used to augment a users view of an industry plant, it provides alternative solutions for design, quality control, monitoring and control, service, and maintenance in complex process industries, such as the aluminium smelting industry. The objective of this paper is to discuss the integration of mobile AR within an aluminium industrial plant, in order to achieve effective fault detection and diagnosis. The possible integration of mobile AR within an aluminium fault detection and diagnosis system is shown with regard to four main functions, namely (1) plant information system, (2) fault history, (3) interactive troubleshooting, and (4) statistical analysis results. This paper opens up possible future works, where the potential use of mobile AR can be explored as an additional user interface component, for increasing the effectiveness of process monitoring within the aluminium smelting process.

Full textAbstract:
Background and Aim: Since 2015, local newspapers reported that pig and poultry farmers in Uganda use antiretroviral drugs (ARVs) to promote growth in animals and control diseases. This study was conducted to assess farmers' knowledge, attitude and perceptions about the use of antiretroviral drugs as boosters in pigs and poultry and the possibility of detecting the antiretroviral drugs in meat using available laboratory methods. Materials and Methods: In 2019, a cross-sectional study was conducted in ten districts in Uganda. In 20 focus group discussions with 100 pig and poultry farmers and 70 animal health service providers, we assessed the use of ARV in livestock enterprises. Subsequently, samples of chicken, pigs, and animal feeds were collected from volunteer participants, and screened for residues of saquinavir, lopinavir, nevirapine, and efavirenz using liquid chromatography-tandem mass spectrophotometer. Results: Participants in all ten districts were predominantly smallholder farmers supplying the local markets. All groups reported the use of ARVs in pigs and broiler birds but not in layer hens. In the absence of good quality feeds, the motivation for feeding ARVs was rapid animal weight gain, as well as the control of animal diseases, for which farmers have no alternative solutions. ARVs were obtained within the community for free, against cash, or in-kind payment. Residues of lopinavir were detected in four, and saquinavir in seven districts, and all three sample matrices. Conclusion: Our study findings confirm anecdotal news reports on ARV use in livestock. While our findings are not generalizable to the whole country, they call for a representative follow-up. As the drugs were detected in tissues destined for human consumption, the potential risk to human health warrants further investigation.

One of the main features of construction as a branch of material production is a wide range of various types of regulations, technical, process flow and methodology documentation, and governing standards determining the conditions for development of design solutions and the formation of the functional quality of construction products. Regulatory control of practical activities in the field of construction should be considered as a necessary tool and most important means of achieving the planned results, bearing in mind, first of all, the quality of organizational and process solutions, methods of construction operations in the specific conditions of a construction site, methods of ensuring control and supervisory measures in simple and complex construction processes. The structure of city-forming factors had changed noticeably by the middle of the twentieth century: the number of people employed in the service sector, education, and the banking sector had grown. The industrial production and transport structure has changed. Society began to impose increasingly stringent requirements on sanitary standards for the functioning of industries and many of them were forced to close down. Science-intensive industries sprang up in major cities to employ the redundant workers. The share of the economically active population employed in scientific and design centers, and medical and educational institutions increased. Relocation of some enterprises outside the major cities in Europe coincided with the perceived need for their radical technical re-equipment. Our country was at least 50-70 years late with these measures, which caused a general technical lag. Intensive housing construction in large cities of Russia has led to the fact that employees often use public and private transportation to get to work from “dormitory” areas in the direction of the center. As market principles for assessing the effectiveness of enterprises allowed for economic reforms, introduction of cadastral changed the structure of the urban economy.

Full textAbstract:
Purpose The purpose of this paper is to find determinants of the effectiveness of the business improvement processes that create value for services offered to patients in healthcare industries. The words patients and customers are used interchangeably throughout without any distinction. The features that distinguish medical services of different types and their inter-related factors are examined. The aim is to come up with a model of value vs cost that can help healthcare managers examine and use this exercise as an example of improvement micro-projects to help reduce cost and eliminate the patient’s dissatisfaction gaps. Design/methodology/approach The list of factors or attributes influencing the creation of value of a given medical process or a single procedure is described. The factors in the value creation are examined that will help in the categories for the risk analysis to determine the value-added benefits for the patient outcome. The cost analysis is approached from two angles to include: the cost of the service, and the costs of poor quality of service. Findings The model describes the value for the patient satisfaction depending on the quality level or grade of the treatment or procedures used and the cost factor. The analysis is done at several levels with special reference to case examples. A search for various analogous models in similar service providing situation used in business process management of other process types is highlighted and discussed. Originality/value The model is an interesting generic illustration for considering value vs cost in all patient care strategies. It enables the position of various medical procedures that can be applied to the same disease in order to keep the variations as minimum as possible within the quality control specification limits. The importance in different aspects of check-points or hold points for inspection is also discussed.

To successfully establish a unified and standardized Internet of Things (IoT) system, a specific scheme based on the bandwidth and quality of service (QoS) analysis as well as the third generation mobile communication system is given. The basic architecture of the IoT is introduced, the technical requirements of each level on the network are put forward, and the application of the IoT system in different industries is established. At the same time, a congestion control algorithm based on the application layer is proposed. This algorithm can greatly enhance the adaptability and controllability of the communication network of the IoT. Moreover, when the system is in normal operation, the algorithm can reasonably allocate and optimize bandwidth resources, thus greatly saving network traffic. The algorithm tests the current network state through the network test module, and then determines whether the data is sent according to the test results to ensure that the system has sufficient resources to respond to the sudden situation.

Full textAbstract:
Purpose – Customer support has always been considered a competitive advantage in many industries. In recent years, firms have begun to provide customers with a high-quality service experience, in order to attract more customers and achieve higher customer satisfaction. Although customer service and satisfaction have been discussed by other researchers, to the knowledge, there has been no dynamic and intelligent way to model and optimize customer support systems for product and service providers. The purpose of this paper is to develop a modeling method for customer support optimization. Design/methodology/approach – In this study, a system dynamics (SD) model has been formulated to investigate the dynamic characteristics of customer support in an IT service provider. The proposed simulation model considers the dynamic, non-linear, and asymmetric interactions among its components, and allows study of the behavior of the customer support system under controlled conditions. Furthermore, a particle swarm optimization method was developed to investigate the proper combination of parameters and strategy development of the support center. Findings – This paper proposes a novel modeling, simulation, and optimization approach for complex customer support systems of information and communications technology (ICT) service providers. This method helps managers improve their customer support systems. Moreover, the simulation results of the case study show that ICT service providers can gain benefit by managing their customer service dynamically over time using the proposed artificial intelligent multi-parameter modeling and optimization method. Research limitations/implications – The proposed holistic modeling approach and multi-parameter optimization method will greatly help managers and researchers understand the factors influencing customer support. Moreover, it facilitates the process of making new improvement strategies based on provided insights. Originality/value – The paper shows how SD simulation and multi-parameter optimization can provide insights into the field of customer support. However, the existing literature lacks a holistic view of these kinds of simulation systems, as well as a multi-parameter optimization method for SD methodology.

Full textAbstract:
Background. There is a paucity of data on asymptomatic carriage of Plasmodium parasite among adult population in Eastern Uganda, an area of perennial high transmission of malaria. In this study, we estimated the prevalence of Plasmodium parasites in donor blood units at Mbale Regional Blood Bank (Mbale RBB), a satellite centre of the Uganda Blood Transfusion Service (UBTS). Method. This was a cross-sectional descriptive study in which 380 screened donor blood units were examined for the presence of Plasmodium parasites. A systematic random sampling technique using the interval of 7 was used in selecting the screened blood units for testing. Two experienced malaria slide microscopists (MC1 and MC2) independently examined each thick and thin blood slide under high power magnification of X400 and then X1000 as stated on the study standard operation procedure (SOP). Each slide was examined for 100 oil immersion fields before the examiner declared them negative for Plasmodium parasites. The results by each microscopist’s examination were tallied separately, and finally, the two tallies were compared. The third independent microscopist (MC3) was blinded to the results from MC1 and MC2, but whose role was to perform quality control on the slides randomly sampled and read 38 (10%) of all the slides and was available to examine any slides with inconsistent findings by MC1 or MC2. Results. All the microscopists were unanimous in all the slide readings. Five of the thick smears (1.3%) confirmed the presence of Plasmodium parasites among donor blood units. Of these, 4/5 were from male donors. Plasmodium falciparum was identified in 4 positive samples, while Plasmodium malariae was identified in one of the donor units. Conclusion. The 1.3% prevalence of Plasmodium malaria parasites in screened donor blood units represents risk of malaria blood transfusion transmitted infection and a pool of community transmittable malaria infections, respectively.

The Internet of Things (IoT) gains momentum. Developments regarding smart grids, intelligent transportation systems, and low-power networks for smart cities constitute significant drivers in the evolution of network industries. IoT creates an array of new requirements for information and communications technology (ICT) data transmission: In addition to real-time and data geopositioning, new service characteristics result from the change of the traditional sender–receiver perspective of Transmission Control Protocol/Internet Protocol (TCP/IP) to content relevancy for many users (e.g. cloud computing) and dynamic changes of the state of devices. The future development and success of IoT hinges critically on the provision of heterogeneous quality of service (QoS) requirements which cannot be provided by best-effort TCP/IP Internet. It is thus not surprising that both in the US and the EU network neutrality regulations are currently being reconsidered. Alternative network logistics (virtual networks) dealing with heterogeneous QoS requirements of network traffic may require fundamental deviations from traditional Internet architectures. Corresponding logistics operating over joint physical infrastructures gain increasing attention under the heading of future networks (FNs). The goal of this article is to focus on the economic mechanisms of how the potentials of QoS differentiation in the context of FNs can be fully exploited and incentivized within innovative all-IP-based QoS traffic architectures.

Full textAbstract:
Nowadays the telecommunications sector is becoming very complex Because of the panoply of high-speed technological services. Customers are abandoning the services offered by telecommunications operators because of their dissatisfaction with the services they offer. «Churn» or the migration of customers from one telecommunications operator to another is the main problem facing the telecommunications industries worldwide. Business managers consider the quality of service to be paramount. As a consequence, they have devised reliable criteria to assess the flow of customers within the market and check and evaluate whether customers are satisfied with the services they are offered. This, in turn, helps to establish customer loyalty and provide a healthy and sustainable trading agreement. Service quality control assessment is pivotal to identify the leverage and evaluate the internal and external competition in the industry. Although this concept is not foreign, rather it is an essential business management tool. The goal of this study is to determine the significant criteria for the cause migration of a Tunisie Telecom customer to another operator. Telecommunication is an essential lifelong component that contributes to the comfortability of our daily lives. The various means of telephone communication play a significant role in improving the effectiveness of communication industry. Every telecommunication operator is aware today that it is cheaper to retain an existing customer than to seek to recruit a new one. Indeed, we noticed that the telecommunications market is characterized by intense competition, where a change in the quality of service or a negative interaction perceived by the customer could risk losing them. As a result, the majority of operators introduce studies and action plans to retain customers and keep them as long as possible. The notion of keeping customers and building loyalty is probably one of the biggest challenges that operators around the world face in global competition. In order to achieve the goals set by telecom operators and to achieve maximum profitability, operators must effectively analyze market data and adopt a most effective targeted communications strategy for their customers. Keywords: churn analysis, customer loyalty, mobile marketing, telecommunications, telecommunications customer.

Purpose The purpose of this paper is to explore various risks that are associated with recruitment process outsourcing (RPO) strategy in the Indian information technology (IT)/IT-enabled service (ITes) industries. Design/methodology/approach Purposeful intensity sampling was used to select respondents from IT/ITes organizations. Twenty-eight respondents were interviewed through face-to-face semi-structured interviews and telephonic interviews. Each interview lasted for approximately 65 min. All interviews were audio recorded with the permission of the respondents and were then transcribed. The data were analyzed with the help of a qualitative technique, thematic analysis. Findings Results show that the stakeholders associated with RPO are not satisfied with several issues such as violation of initial contact between the applicant and the potential employer, violation of contracts by the vendor, unfair practices by the vendor, poor quality service provided by the vendor, plausibility that the vendor does not understand the culture of the client organization, inappropriate placement of human resources by the vendor, low morale of the employees and loss of managerial control due to RPO. Research limitations/implications Small sample size and qualitative research design reduces the external validity of the findings to certain extent. Practical implications Companies deploying RPO should be wary about the plausible negative consequences. This paper offers various solutions to mitigate such risks. Originality/value This paper is a novel attempt which details various risks due to deployment of RPO from multiple stakeholder perspectives.

Full textAbstract:
Efficient information flow in an intelligent system is vital for effectively controlling the entire system. Currently, intelligent systems are used in many industries related to energy production, sustainable agriculture/transport, and intelligent building/cities. Information technology (IT) and information and communication technologies (ICT) play vital roles in introducing technical or technological innovation in these industries as well as establishing a collaborative network. Also, the digitization of existing systems has been quite effective at creating a sustainable global environment as it allows more efficient and well-balanced control of socio-economic factors. However, it has become clear that adopting an intelligent system to achieve innovation, sustainability, and safety may well depend on the quality of the algorithms to be used for that very system. Despite recent controversies, new and renewable energies are considered as a realistic alternative to fossil fuels, which have been integral to modern industries but are regarded as a cause of environmental or economic problems, not to mention their limited deposits. Therefore, since renewable energies will gradually replace existing energy sources but require more time to be fully available, it is essential to find a method of managing them in a fair and transparent way. The United States, Japan, and some European countries are attempting to achieve such a goal by utilizing a blockchain system, but the issues pertaining to its functionality, security, or efficiency have yet to be addressed. This study introduces a viable consensus algorithm (Hyper Delegation Proof of Randomness, or HDPoR algorithm) for blockchain and attempts to validate its parallel computing capability through simulations. This study also attempts to design an efficient but secure peer-to-peer (P2P) transaction service model for these energies for the future where blockchain-based systems will hold a key position in the digitalized world. As its main contribution, this study introduces an effective method of applying blockchain to a new and renewable energy transaction system by presenting a consensus algorithm that can improve its infrastructure and performance.

Full textAbstract:
PurposeAlthough additive manufacturing (AM) has been demonstrated to have significant potential in improving spare part delivery operations and has been adopted to a degree in the aviation and automotive industries, its use in spare part production is still limited in other fields due to a variety of implementation barriers. The purpose of this article is to assess the significance of previously reported barriers in the context of the machine-building industry.Design/methodology/approachAdoption barriers are identified from the literature and formulated as hypotheses, which are verified with a set of focus group interviews consisting of original equipment manufacturers (OEMs), AM service providers and quality inspection and insurance institutions. The results of the interviews are reported qualitatively, and the transcripts of the interviews are subjected to quantitative content analysis.FindingsThe article identifies distrust in quality, insufficient material and design knowledge among stakeholders and poor availability of design documentation on spare parts as the key barriers of adopting AM in the production of spare parts. The three key barriers are interconnected and training engineers to be proficient in design and material issues as well as producing high-quality design documentation will yield the highest increase in AM implementation in spare parts.Originality/valueThe article offers a unique approach as it investigates the subjective views of a cross-organizational group of industrial actors involved in the machine-building industry. The article contributes to the theory of digital spare parts by verifying and rejecting presented barriers of AM implementation and how they are interconnected.

Full textAbstract:
Agriculture differs from other sectors of the economy by the presence of various forms of ownership, as well as the discrepancy between the calendar year and the production year. Therefore, for organizations specializing in the production and processing of products in agriculture, it is very difficult to choose programs for automating cost, operational and tax accounting. But, at the present stage, automation is necessary to maintain the competitiveness of the enterprise. In a market economy, planning is one of the most important management functions. The volume and quality of information provided by the accounting service is of great importance for proper and prompt financial planning. From this point of view, in our opinion, the system for organizing production, accounting, control and budgeting is relevant. Automation of budgeting in agro-industrial organizations will ensure production efficiency, increase productivity and labor efficiency, as well as competitive products manufacturing. The article describes the features of the introduction and application of information technologies, taking into account the specifics of agricultural industries. The theoretical and methodological possibilities of the automated budgeting system for the enterprises of the agro-industrial complex are also considered and analyzed. In summary, the main conclusions on improving automated cost accounting and budgeting are formulated.

Full textAbstract:
The exponential rise in wireless technologies and allied applications has revitalized academia-industries to develop more efficient and economic routing solution to meet Quality-of-Service (QoS) provision. Amongst the major wireless communication systems, Wireless Sensor Network (WSN) is the most sought technology for defense surveillance, healthcare monitoring, industrial monitoring and control, civic and strategic infrastructure surveillance etc. Additionally, the up surge in Internet of Things (IoT) and Machine to Machine (M2M) communication systems too have broadened the horizon for WSNs based communication. However, the parallel increase in communication environment, complex network conditions etc confine efficacy of the classical WSN protocols. Dynamic network and node conditions often force classical protocols to undergo pre-mature link outage, delayed transmission, energy exhaustion and eventual QoS violation. To address such issues enhancing Median Access Control (MAC) and allied routing decision can have vital significance. However major existing efforts either focus on MAC enhancement or routing optimization, even under static WSN topology. Considering it as motive in this paper a highly robust “Cross-layer architecture based Joint-Synchronous MAC and Routing Protocol for WSN communication (JSMCRP)” has been developed. Being cross layer model JSMCRP protocol employs Application Layer, Network Layer, MAC Layer and PHY Layer to perform Network Adaptive MAC scheduling and Dynamic Routing Decision. JSMCRP employs Data Traffic Assessment, Prioritization and Scheduling (DTAPS), Proactive Network Monitoring and Knowledge (PNMK), Dynamic Congestion Index Estimation (DCIE), Adaptive Link Quality, Packet Injection Rate and Cumulative Rank Sensitive Routing Decision (CRSRD) to perform routing decision. Additionally, exploiting dynamic network/node conditions it performs Cognitive MAC scheduling to ensure QoS centric communication over IEEE 802.15.4 protocol stack. JSMCRP exhibited higher PDR, lower PLR and low delay under varying network conditions, suitable for real-time communication over constrained mobile WSN conditions.

Besides energy saving that is possible to achieve, another positive side effect of this is the reduction of the working temperature of internal components of telecommunications devices (switches, home gateway, routers, etc.). This idea is encouraging the development of routers of reduced dimensions as long as there is the knowledge that the temperature remains in a given range. For this reason the target of this paper is to propose a governor policy that provides the best trade-off between quality of service and energy saving in respect of a given target on the working temperature. More specifically, such a governor is in charge to manage the clock frequency of the Central Processor Unit (CPU) of the green router according to the traffic loading the router, varying the processing engine performance, the working temperature and the power consumption of the hardware at the same time. The proposed policy is then applied to a case study and evaluated by simulation to show how it can be used for the above purposes, and to allow green router designers to control the temperature statistics of a router and design the governor parameters to maintain the mean temperature below a given threshold.

Computer spare parts (CSPs) inventory management (IM) is very important for many companies. Excess inventory leads to high storage costs. On the other hand, the lack of CSP has a strong impact on the quality of service. This study was conducted by Power-One Jordan Computer Hardware-Software company (POJCHSC), Amman, Jordan. The focus area was the IM department and the target sample was employees working in the management department. The results showed that factors influencing the management of slow moving CSPs include production costs, obsolescence and CSPs dependence availability and transportation costs. By forecasting during the study, the results showed that the demand for adapters and chargers would increase by 20%. This demand forecast was performed using the economical order quantity (EOQ) model. The percentage of profits made by this company is 48%, and this requires some intervention to prevent losses. The results of this study are useful to the company, as well as to other similar industries that deal with slow-moving items. These results will help to simplify IM of slow-moving items. When we focused on POJCHSC manufacturers, the disadvantages of using the traditional ABC classification model were identified. Therefore, there is a need to have an ABC classification that is improved and which takes into consideration the criticality of the slow-moving CSP.

In recent years, research has been carried out to study the problems of improving the organization of dental care for both the General population and individual categories of industrial workers4,6. However, to date not carried out in-depth studies on the problems of improvement of dental care to employees of the chemical industry in the new socio-economic conditions of development of industrial complex and reform of the health system, there is no comprehensive study of the current status of dental service medical-sanitary unit (MSCH) large enterprises, comparison of availability and quality of dental care to employees at the place of residence and place of work. The purpose of this review is to study the dental morbidity of chemical workers, develop measures to improve their dental health and improve the quality of life. At the present stage of development of the industrial complex of our country, a number of large enterprises have the opportunity to organize dental care for employees, primarily with harmful working conditions, at a higher level. At the same time, the implementation of the preventive orientation in dental care for the working population remains an unsolved problem2,3. The successful functioning of any medical service in modern conditions is possible only with the optimal interaction of all parts, all elements of the health system depends largely on the level of organization and management of medical institutions to optimize their work7,8. Keywords: Condition of the mucous membrane of the oral cavity, the hard tissues of teeth and paradontium, taste analyzer, unfavorable factors of production. Material And Methods Of Research: It is planned to conduct a study of 120 workers of JSC "samarkandkime" - the main group, as well as 115 patients who applied to polyclinic No. 10 and are not related to the chemical industry - the control group. The data that was received was subjected to statistical processing using the Microsoft Excel application package. The reliability of the difference in parameters was determined by the student's criterion. Results and discussion.Currently, the issues of dental health for workers in various industries are relevant. Various harmful factors of production can have a negative impact on human health, including on the tissues of the teeth, periodontal, oral and lip mucosa.

Purpose – The purpose of this paper is to assess the status of Six Sigma's status in Brazilian companies and understand the integration of this program with other quality management approaches. Additionally, the critical success factors (CSFs) for Six Sigma implementation and primary Six Sigma program characteristics were identified. Finally, the results of the used of Six Sigma were analysed. Design/methodology/approach – An extensive literature review illustrates the primary Six Sigma characteristics and its relationship with other quality approaches. The research methodology encompasses survey development and statistical analyses. Questionnaires are distributed to 1,000 large firms in the manufacturing and service industries in Brazil. Altogether, a total of 198 firms, of which 46 companies adopted the Six Sigma program, participated in this study. Findings – The results suggest a synergic and incremental pattern of quality model implementation. The study reveals that companies that have adopted Six Sigma have a long history of implementing quality programs, which suggests a certain level of quality maturity. The studied companies perceive in Six Sigma an incremental evolution, which can be combined with earlier initiatives and provides strong synergy with ISO 9000. The findings of this study confirm the distinctive Six Sigma role structure suggested by several authors. However, three possible configurations of the role structure were found that differ in terms of training and the dedication of human resources involved in the Six Sigma program. Research limitations/implications – This study demonstrates the inherent limits of the research method adopted, the use of a non-probabilistic sample and a reliance on self-reported perceptions, which introduces bias to the analysis. Practical implications – Important managerial implications of this study are related to the Six Sigma structure adopted. The capillarity of the program in the organisation as a whole can be related to the type of role structure configuration adopted. This structure can have an impact in terms of both numbers and employees’ and managers’ degree of involvement, as well as the type of training and resources provided. Originality/value – The diffusion of Six Sigma in Brazilian companies is less widespread than in other countries. Three possible configurations of the role structure were found that differ in terms of the training and dedication of human resources entailed by the Six Sigma program. Three CSFs factors were identified: organisation, infrastructure and human resources.

Full textAbstract:
We live in a time when dialogue systems are becoming a very popular tool. It is estimated that in 2021 more than 80% of communication with customers on the first line of service will be based on chatbots. They enter not only the retail market but also various other industries, e.g., they are used for medical interviews, information gathering or preliminary assessment and classification of problems. Unfortunately, when these work incorrectly it leads to dissatisfaction. Such systems have the possibility of contacting a human consultant with a special command, but this is not the point. The dialog system should provide a good, uninterrupted and fluid experience and not show that it is an artificial creation. Analysing the sentiment of the entire dialogue in real time can provide a solution to this problem. In our study, we focus on studying the methods of analysing the sentiment of dialogues based on machine learning for the English language and the morphologically complex Polish language, which also represents a language with a small amount of training resources. We analyse the methods directly and use the machine translator as an intermediary, thus checking the quality changes between models based on limited resources and those based on much larger English but machine translated texts. We manage to obtain over 89% accuracy using BERT-based models. We make recommendations in this regard, also taking into account the cost aspect of implementing and maintaining such a system.

Based on the Investigation of 78 Airports." Mathematical Problems in Engineering 2021 (June 21, 2021): 1–14. http://dx.doi.org/10.1155/2021/8387088.
Full textAbstract:
China’s regional economic competition is intensifying; in particular, the cluster development of air transport, high-end manufacturing, and modern service industries is closely related to the construction of regional airports. Local governments have listed aviation hubs as the hardcore advantage of high-quality growth in the new era, but it may also lead to excessive convergence and preferential system competition. Based on the “GDP competition” of local governments in China, this paper uses panel data of 78 airports in mainland China from 2001 to 2018 and tries to explore the causes of airport preferential policies. The Synthetic Control Method is used to study the influence of preferential policies on airport passenger and cargo flow, and then the Spatial Durbin Model is used to verify the spatial spillover effect of aviation hubs, which may be magnified by the preferential policies. This paper finds that the impact of preferential policies on airports in central and western China is mainly reflected in the increase of cargo throughput, and there is a spatial siphon effect on cargo throughput between airports. The implementation of the preferential policy enhances this spatial siphon effect, which in turn leads to more fierce competition. The research results show that the preferential policies, issued in central and western aviation economy, have shown a trend of evolving in the direction of vicious competition. Before the airport preferential system produces more negative effects, it should be corrected in time, and each aviation economic zone in the central and western regions should be scientifically coordinated and reasonably planned.

Full textAbstract:
In the Lower Mekong River Basin (LMB), deforestation rates are some of the highest in the world as land is converted primarily into intensive agriculture and plantations. While this has been a key for the region’s economic development, rural populations dependent on the freshwater water resources that support their fishing and agriculture industries are increasingly vulnerable to the impacts of flood, drought and non-point source pollution. Impacts of deforestation on ecosystem services (ES) including hydrological ES that control the availability and quality of fresh water across the landscape, regulating floods and droughts, soil erosion and non-point source pollution are known. Despite this understanding at the hillslope level, few studies have been able to quantify the impact of wide-scale deforestation on larger tropical watersheds. This study introduces a new methodology to quantify the impact of deforestation on water-based ES in the LMB with a focus on Cambodia by combining spatial datasets on forest loss from remote sensing and spatially-explicit hydrological modeling. Numerous global and regional remote sensing products are synthesized to develop detailed land use change maps for 2001 to 2013 for the LMB, which are then used as inputs into a hydrological model to develop unique spatial datasets that map ES changes due to deforestation across the LMB. The results point to a clear correlation between forest loss and surface runoff, with a weaker but upward trending relationship between forest loss and sediment yield. This resulted in increased river discharge for 17 of the 22 watersheds, and increased sediment for all 22 watersheds. While there is considerable variability between watersheds, these results could be helpful for prioritizing interventions to decrease deforestation by highlighting which areas have experienced the greatest change in water-based ES provision. These results are also presented in a web-based platform called the Watershed Ecosystem Service Tool.

Purpose Supply chain management (SCM) focuses smart logistics and quality service. Diverse elements such as design, procurement, production and sale policies are the keys to SCM efficiency. Due to worsening environmental pollution in recent years, many businesses, government agencies and consumers have become more aware of greenhouse gases (GHG) emissions. In response, the government has established new environmental regulations to control various GHG, such as CO2 and sulfur dioxide. Therefore, to reduce pollution and its adverse effects, the authors have promoted environmental concerns by developing environmental friendly policies. The purpose of this paper is to develop a multi-objective decision making model that integrates both forward and reverse logistics to determine how best to incorporate recycling and reduce manufacturing costs. Design/methodology/approach In this study, the authors developed a multi-objective decision-making model that integrates both forward and reverse logistics to determine how best to incorporate recycling and reduce manufacturing costs. They used the normalized normal constraint method as proposed by Messac et al. (2003) to generate a series of uniform lines on a Pareto Frontier chart. Findings Based on the results of this study, the authors can determine the trade-off between costs and emissions and design the most environmental-friendly and economical strategy for production. Research limitations/implications This study is limited to a case study on paper manufacturing. Practical implications The authors considered the full truckload discount policy in which buyers can reduce their purchase costs by increasing the number of full truckload product orders; this will reduce transportation costs and also minimize overall carbon emissions. Social implications This study encourages industries to focus on environmental friend policies and social responsibilities. Originality/value The authors investigated the impacts of the paper making industry on economy and environment. An increase in demand will negatively impact the environment by causing CO2 emissions to increase from higher production and the felling of more trees to provide raw materials for manufacturers (paper mills).

Goal. The purpose of this article consists in analyzation and systematization of the leading conceptual framework of brand management as well as in additional investigations of its influence on tourist destination development. Method. The methodological basis of the research is the basis of scientific dialectics. The main methods of research are the method of formalization, algorithm development, descriptive, analytical and synthetic. Results. Brand management is an actual area of scientific researches in the context of its role in tourism. The brand creates a difference of a trademark or service from competing ones, helps to increase sales and generally increases profits in the long-term perspective. Therefore, the formation of the brand requires the serious approaches and the involvement of skilled managers. The practice of tourist centers or territories brands creation is widely used now, which is fully justified, as the positive image of cities or regions contributes to the creation of additional profits from attracting new tourists. The main functions of the tourist destination brand are related to: - the formation of an individual image (image) of the destination, which distinguishes it from its competitors; - ensuring its recognition by choosing a market position for the tourist product of the destination; - confirmation of the quality of the tourist product of the destination; - a positive influence on the formation of corporate consciousness of the population of the tourist territory (region, destination). The key task of branding the tourist destination is to establish position and strengthen its strengths, which should serve as the basis for the formation of the brand. Specificity of branding of tourist territories as a complex of marketing actions undertaken by their management in cooperation with stakeholders (various stakeholders) for the creation and promotion of the brand is that: - the product of the destination is multifaceted, including a number of goods and services of various industries; - the management of the destination does not have full control over the marketing complexes (marketing mix); - teamwork is required taking into account the interests of all stakeholders; - significant influence is rendered by the policy of the country / region in the field of tourism. Practical significance. But the creation of the city's tourist brand is not chaotic. The process of its formation is under the influence of a number of regularities and principles that are considered in the article. Scientific novelty. Modern ways of promoting tourism product take place in the context of globalization and information society development and also increase competition for consumers. Crucial conditions for survival on rigid travel market are the need for concentration on a high-quality tourism product, able to satisfy the highest demands of modern tourism consumer, and promote itself to the market. Therefore, the process of creating a brand of tourist destination as well as investigations of its influence on positioning, identity and development of tourism destinations are represent the maim scientific novelty of this article.

The resource and operational characteristics of the rolling tribosystems and the normal operation of machines and mechanisms as a whole substantially depend on the cleanliness of their working surfaces. As a result of increasing the cleaning efficiency by tribo-tilting machines and lubricating fluids, the life of the mechanisms of these machines can be increased by 2-3, and in cases with precision assemblies - up to 10 times. Thus, the provision and control of the purity of the rolling tribosystems will allow to improve their performance and increase the resource today is a relevant scientific and technical task. One of the ways to increase the service life and improve the performance of rolling bearings is the effective removal of contamination from working surfaces, is of particular importance for special and precision bearings, which are widely used in various industries, and helps prevent their premature wear and maintenance and repair costs. Literary analysis and research results showed that vibroacoustic parameters (vibration velocity and vibration accelerations), as the main parameters of the quality of the tribosystem rolling, directly depend on the accuracy of manufacturing and assembly, as well as on the cleanliness of working surfaces and the absence of various kinds of pollution, including metallic ones.

Background:Physical function is a core domain to be measured in randomized controlled trials (RCTs) of psoriatic arthritis (PsA). The discriminative performance of patient reported outcome measures (PROMs) for physical function (PF) in RCTs has not been evaluated systematically.Objectives:In this systematic review, the GRAPPA-OMERACT working group aimed to evaluate the clinical trial discrimination of PF-PROMs in PsA RCTs.Methods:We searched PubMed and Scopus databases in English to identify all original RCTs conducted in PsA. We limited the review to RCTs of biologic and targeted synthetic DMARDs. Groups of two researchers extracted data independently for PF-PROMs. We assessed quality in each article using the OMERACT good method checklist. Effect sizes (ES) for the PF-PROMs were calculated and appraised usinga priorihypotheses. Evidence supporting clinical trial discrimination for each PF-PROM was summarized to derive recommendations.Results:32 articles were included (Figure 1). Four PF-PROMs had data for evaluation: HAQ-Disability Index (DI), HAQ-Spondyloarthritis (S), Short Form 36-item Health Survey Physical Component Summary (SF-36 PCS), and the Physical Functioning domain (SF-36 PF) (Table 1). The ES for intervention versus (vs.) control arms for HAQ-DI ranged from -0.55 to -1.81 vs. 0.24 to -0.52; and for SF-36 PCS ranged from 0.30 to 1.86 vs. -0.02 to 0.63.Table 1.Summary of Measurement Properties Table for clinical trial discriminationArticlesHAQ-DIHAQ-SSF-36 PCSSF-36 PFAntoni 2005 (IMPACT); Gottlieb 2009 (UST)+Antoni 2005 (IMPACT2)++Kavanaugh 2006 (IMPACT2)+Mease 2005 (ADEPT); Genovese 2007 (ADA); Mease 2010 (ETN); Kavanaugh 2009 (GO-REVEAL); Kavanaugh 2017 (GO-VIBRANT); Gladman 2014 (RAPID-PsA); Mease 2015 (FUTURE1); McInnes 2015 (FUTURE2); Kavanaugh, 2016 (FUTURE2)-subgroup; Nash 2018 (FUTURE3); Mease 2017 (SPIRIT-P1); Nash 2017 (SPIRIT-P2); Deodhar 2018 (GUS); Mease 2016 (CLZ)++Mease 2000 (ETN); McInne, 2013 (PSUMMIT 1); Ritchlin 2014 (PSUMMIT 2); Araugo 2019 (ECLIPSA)++Gniadecki 2012 (PRESTA)+Mease 2019 (SEAM-PsA)+/-+McInnes 2014 (SEC)++Mease 2014 (BRO)++Mease 2011 (ABT)+/-+Mease 2017 (ASTRAEA)++Mease 2006 (ALC)+/-Mease 2017 (OPAL Broaden); Gladman 2017 (OPAL Beyond)++Mease 2018 (EQUATOR)++Mease 2018 (ABT-122)+Total available articles311244Total articles for evidence synthesis291232Overall rating+++Color code in each box indicate study quality by OMERACT good methods. GREEN: “likely low risk of bias”; AMBER: “some cautions but can be used as evidence”; RED: “don’t use as evidence”. WHITE (empty boxes): absence of information from that study. (+): findings had adequate performance of the instrument; (+/-): equivocal performance; (-): poor performance (less than adequate).Conclusion:Clinical trial discrimination was supported for HAQ-DI and SF-36 PCS in PsA with low risk of bias; and for SF-36 PF with some caution. More studies are required for HAQ-S.Disclosure of Interests:Ying Ying Leung Speakers bureau: Novartis, Janssen, Eli Lilly, Richard Holland: None declared, Ashish Mathew: None declared, Christine Lindsay Employee of: Previously employed (worked) for pharmaceutical company., Niti Goel Shareholder of: UCB and Galapagos, Consultant of: VielaBio, Mallinckrodt, and IMMVention, Alexis Ogdie Grant/research support from: Novartis, Pfizer – grant/research support, Consultant of: AbbVie, BMS, Eli Lilly, Novartis, Pfizer, Takeda – consultant, Ana-Maria Orbai Grant/research support from: Abbvie, Eli Lilly and Company, Celgene, Novartis, Janssen, Horizon, Consultant of: Eli Lilly; Janssen; Novartis; Pfizer; UCB.
