Full textAbstract:
Approved for public release; distribution is unlimited.This research was conducted in response to a request by the Navy Manpower Analysis Center. The research examined the Preventive Maintenance to Corrective Maintenance Ratio (PM:CM) as part of the Ship Manpower Document (SMD) requirements development process. Established in 1968, the PM:CM ratio has never been revised. Previous research indicates that the PM:CM ratio used by NAVMAC underestimates actual CM performed on board ships. The research examined the 1:1 (electrical) and 2:1 (mechanical) ratios used to accurately forecast CM. The study analyzes effects to the SMD when actual Open Architectural Retrieval System (OARS) CM data is used. This study used one Engineering and one Combat Systems work center as a baseline. CM OARS data for the work centers was provided by NAVSEA and PM data was provided by NAVMAC. Findings indicate that across all DDG [flights], the PM:CM ratio understates the amount of CM performed. The resulting ratio for electrical maintenance was 1:10.9 and for mechanical maintenance 1:1.64. When CM from OARS was used to determine SMD requirements as outlined in OPNAVINST 1000.16K, it resulted in increased functional work on all flights of DDGs.

Previous issue date: 2011presente trabalho propõe um modelo para a manutenção imperfeita sob ações corretivas e preventivas dependentes. O modelo é baseado no acoplamento entre um modelo de Riscos Competitivos (o modelo de alerta de reparação) e Processo de Renovação Generalizado. Normalmente, os Processos de Renovação Generalizados são capazes de capturar a qualidade da manutenção executada como sendo perfeita, mínima ou imperfeita, porém eles não conseguem distinguir entre os tipos de falhas. Por outro lado, Riscos Competitivos é uma metodologia que é capaz de captar os diferentes tipos de falhas - e, consequentemente, os diferentes tipos de manutenção (corretiva e preventiva) - não podendo, no entanto, estudar sistemas reparáveis. Portanto, o modelo híbrido proposto neste trabalho é capaz de preencher a lacuna das duas metodologias através de um modelo robusto. O modelo proposto é caracterizado através da construção de funções probabilísticas, o desenvolvimento de um teste de hipótese para verificar a sua aplicabilidade, e estimadores de máxima verossimilhança obtidos através da técnica conhecida como otimização por enxame de partículas. Um exemplo de aplicação de dados de falha de um sistema de compressor offshore é fornecido e os resultados mostram que o modelo proposto prevê um melhor ajuste aos dados de falha do que outro modelo disponível na literatura com base na abordagem Intensity Proportional Repair Alert+Brown Proschan

Full textAbstract:
Phishing is an internet security issue whose shape is still changing and size is still increasing.
This thesis shows the possibility of a phishing attack on open, private Wireless LANs. Private
WLANs which use a login page to authenticate users in hotels, airports and academic campuses
are all vulnerable to this attack. Virginia Tech's WLAN is used as an example to show that the
attack is possible. The attack combines two very well known attacks: one is to deceptively guide
a user into logging into a fake website, which shows similar log-in page to the page of the
website the user intends to go to, and the second attack is to show users a valid certificate, which
does not show a warning. The rogue server takes the user to a log-in page which is similar to
Virginia Tech's log-in page and shows him a valid security certificate.
We present a solution to the proposed problem. Software is implemented that runs on Windows
Vista. The software warns the user if there are servers with more than one type of security
certificates, claiming to be from the same network. We contrast our method to already existing
methods, and show in what respects our solution is better. The biggest advantage of this method
is that it involves no change on the server side. It is not necessary for the users to have any prior
knowledge of the network, which is very helpful when the users access WLAN at airports and
hotels. Also, when using this method, the user does not need to connect to any network, and is
still able to get a warning. It however, requires the user to be able to differentiate between the
real and fake networks after the user has been warned.Master of Science

Full textAbstract:
A quasi-renewal process is more realistic in modeling the behavior of a repairable system than traditional models such as perfect repair and minimal repair since it reflects the deterioration process of the system over time while traditional models do not. The quasi-renewal parameter is set to a value between 0 and 1 to indicate the rate of deterioration. Moreover, a quasi-renewal process can also be used to model the increasing time of maintenance actions due to the increasing difficulty of maintaining an aging system by setting the parameter to a value larger than 1. We construct a model where the operating times follow a quasi-renewal process and the corrective/preventive maintenance times follow another quasi-renewal process. A quasi-renewal function and two equivalent point availability expressions are developed for the model described by a quasi-renewal process with and age-dependent preventive maintenance policy. In addition, numerical results from various theoretical distributions are obtained to illustrate the behavior of the models. The two equivalent point availability functions each contains an infinite sum and must be truncated to obtain a numerical approximation. The two approximated point availability functions form upper and lower bounds on the real value. The bounds are useful for determining the result accuracy, which can be arbitrarily increased by adding more terms to the truncated summation. Our framework provides a new time-dependent availability model for a non-stationary process with a preventive maintenance policy without any cost structure or optimization problem.Ph. D.

Buhagiar, Roberta. "Development of a quality of life measure for adults with bilateral cochlear implants." Thesis, University of Southampton, 2012. https://eprints.soton.ac.uk/351341/.
Full textAbstract:
Cochlear implants (CI) provide a sense of hearing to people who are severely or profoundly deaf. A single CI (unilateral) has been shown to improve quality of life (QoL) substantially and clinical practice is evolving towards two per patient (bilateral), although the incremental benefit for QoL has not yet been established definitively. There is a need for self-report measures designed specifically to quantify benefits for QoL in patients who receive a second CI, in order to evaluate the relative benefits of unilateral and bilateral implantation. The aim of the present study was to develop and validate such a measure that is suitable for adults. The sample consisted of patients from the United Kingdom National Health Service who have received two CI sequentially. The study was based on the ‘Rolls Royce’ approach. A retrospective open-ended questionnaire and face to face interviews were carried out in the first stage. Categories from the qualitative data obtained from the responses were identified and these were the foundations on which a close-ended questionnaire was developed. In the second stage, face validity, test-retest reliability and correlations of each item were investigated and amendments were made to the questionnaire items to reflect these results. In the last stage participants were asked to fill in the amended questionnaire together with another three existing QoL questionnaires (generic and disease-specific ones). These results showed that the questionnaire under development is valid and reliable. Responses from the participants also gave an insight into the changes that they experienced as a result of receiving a second CI. The main reports were related to experiences of increased confidence and independence levels as a result of having bilateral CI. Improvement in listening in group situations and localisation ability were also noted. Changes in participant experience were evident when they filled in the questionnaire under development and also the Speech, Spatial and Qualities of Hearing questionnaire. Better understanding of changes in QoL after receiving a second CI will help professionals to understand the benefits of bilateral implantation in adults from the users’ perspectives. This is considered to be important when deciding whether patients should be advised to opt for unilateral or bilateral CI in the future. This knowledge will also help prospective patients understand the practical benefits and limitations of one or two cochlear implants.

Full textAbstract:
Obesity and eating disorders are major public health problems in the U.S. Prevention of these problems in childhood and adolescence is crucial to avoid medical complications and costs associated with these conditions. A growing body of research supports designing and implementing interventions to prevent obesity and eating disorders simultaneously by targeting common risk factors such as poor body image. This study explored the use of a body image education unit as a preventive measure for obesity and eating disorders. Ninth-grade students attending health class in a public school in Northern Utah (n = 117) were assigned to either an intervention or control group. At the end of a 3-week nutrition unit, the intervention group received a 3-day intervention designed to promote body image. Participants were surveyed at baseline, immediately following the nutrition unit and intervention, and at a 2-month follow-up. At post-test and follow-up, participants in the intervention group and the control group both self-reported improved body image and dietary practices. Modest improvements were seen in both the intervention and control groups. The intervention group did not have any advantage over the control group. It is recommended that future interventions be of greater intensity and longer duration in order to assess use of body image education to improve body image and dietary constructs. Interventions will have the greatest effect sizes if they target high risk individuals. Universal interventions targeting entire schools and communities are also recommended to help change environmental risk factors and reduce risk in those who may be at high risk but would not be included in a high risk grouping for a targeted intervention.

Lo, Wai. "Breath by breath analysis of breathing pattern in health and disease : a potential outcome measure for breathing retraining?" Thesis, University of Southampton, 2013. https://eprints.soton.ac.uk/351928/.
Full textAbstract:
Analysis of breathing pattern can quantify parameters of breathing such as rate, volume, timing and regularity/rhythmicity. This information can be useful to compare breathing patterns in those healthy and with disease, under different experiment conditions (such as rest versus activity) and to monitor changes over time. In this research, respiratory inductive plethysmography (RIP) was used to record breathing patterns in a group of healthy subjects and a group of severe asthma patients. RIP is a leading technology for ambulatory monitoring of breathing, but traditional RIP devices suffered from poor signal quality under such conditions due to movement of the sensor. Several authors have also raised doubts about the existing calibration methods for RIP which can lead to inaccurate estimation of breathing parameters. During the first phase of the programme, an instrumented garment (LifeShirt®) which had RIP embedded within was tested for its validity in comparison to a pneumotachograph (PT). The first study sought to validate the measurements obtained from the LifeShirt ®against PT when calibrated with a published but yet to be tested method for breath by breath analysis and to address the limitations of existing calibration methods. Eleven healthy individuals took part in this first study. Breathing patterns were simultaneously monitored by the LifeShirt ® and the PT during thirty minutes of rest and twenty minutes of exercise. Parameters of tidal volume, expiration time and tidal volume variability were recorded and compared between devices. The analysis from the first study demonstrated that RIP recorded proportionate changes of tidal volume and expiration duration relative to PT during quiet breathing and exercise. Mean tidal volume and expiration duration between devices was strongly correlated for rest and exercise. No statistical difference in tidal volume variability was observed between devices during either period. Significant differences in expiration duration between devices were observed in all participants at rest but not during exercise. Results of this first study demonstrated that valid breath by breath analysis using RIP without PT was feasible. This is clinically advantageous due to simplicity of set-up for RIP. In the second phase, measurement of breathing patterns was made in severe asthma patients with the LifeShirt® alone during thirty minutes of rest. It intended to add new knowledge with regards to the breathing patterns within this small population as compared to the healthy population. Ten healthy individuals and ten patients diagnosed with severe asthma took part in the second study. Breathing parameters of tidal volume, inspiration time, expiration time, end tidal carbon dioxide levels, tidal volume variability and end tidal carbon dioxide levels variability were recorded by the LifeShirt®. The analysis of the second phase shown no evidence that breathing pattern parameters could differentiate between the severe asthma patients and healthy volunteers in our small study. The symptoms of hyperventilation found more commonly in the severe asthma group were not associated with differences in breathing pattern parameters. However, considerable differences were found between individuals. This suggests the existence of individuality in breathing patterns between individuals. Such findings raised doubts as to whether there is a group ‘pattern’ that is common within the severe asthma population or within the healthy population. This programme calls for a change in paradigm to consider breathing patterns as an unique individual ‘trait’ rather than as a group characteristic.

Full textAbstract:
Management system for enhancing transfer of knowledge in wind power industry has not received sufficient research attention in recent times. In some cases, the wind power plant owner does not control the management system for operation and maintenance activities. Most of these wind power plants are under contract and rely upon the turbine vendor to perform most of the maintenance works and subsequently share their experience at the initial stage of operation. This research investigates the management system for the operations and maintenance activities of the offshore wind plant in Lillgrund. The research also explores the type of learning method that was adopted by the wind turbine vendor (Siemens) to transfer the operation and maintenance knowledge to the operator and owner (Vattenfall) within the speculated period. It was realized that in the next one year, the Vattenfall would be in full control of the operations and maintenance activities of the offshore wind power plant in Lillgrund. The co-management arrangement will give Siemens a good reputation and gainful experience in the wind power industry. The arrangement is achievable due to Siemens strategy to strive for constructive and long-standing relationships with their customer, based on trust, respect, and honesty. Vattenfall on the other hand, is aiming to be the partner of choice for their suppliers at the same time as best serving their internal customers. The provision for the training during the co-management period enables Siemens to strengthen their relationship with Vattenfall in this industry. In addition, Siemens also maintain close relationship with their customers and develop a large part of their portfolio, frequently on site. Vattenfall improves profitability and value creation, as a fundamental prerequisite for continued growth. The management systems of Vattenfall can be related to professional bureaucracy, this is due to the fact that it was organized to accommodate Siemens experts. Vattenfall benefits from the co-management activities of the operation and maintenance of the Lillgrund wind power plant for a specific period of time. The outcome of the research work has proven that there is an effective time-dependent proportionality for a gradual transfer of the technical knowledge of operation and maintenance from Siemens Wind AB to the Vattenfall personnel. The research started from the perspective of the maintenance method by Swedish standard for wind power, and the way things are being carried out in a more practical way in Lillgrund plant.

Full textAbstract:
Objective To evaluate the Structured Interview for Tanning Abuse and Dependence (SITAD).
Design Longitudinal survey.
Setting College campus.
Participants A total of 296 adults.
Main Outcome Measures The SITAD modified items from the Structured Clinical Interview for DSM-IV Axis I Disorders that focus on opiate abuse and dependence. Indoor tanning (IT) behavioral patterns and opiate-like reactions to tanning were measured, and IT behavior was measured 6 months later.
Results Of 296 participants, 32 (10.8%) met the SITAD criteria for tanning abuse (maladaptive pattern of tanning as manifested by failure to fulfill role obligations, physically hazardous tanning, legal problems, or persistent social or interpersonal problems) and 16 (5.4%) for tanning dependence as defined by 3 or more of the following: loss of control, cut down, time, social problems, physical or psychological problems, tolerance, and withdrawal. The IT frequency in dependent tanners was more than 10 times the rate in participants who do not meet the SITAD criteria for tanning abuse or dependence. Tanning-dependent participants were more likely to report being regular tanners (75%; odds ratio, 7.0). Dependent tanners scored higher on the opiate-like reactions to tanning scale than did abuse tanners, who scored higher than those with no diagnosis.
Conclusions The SITAD demonstrated some evidence of validity, with tanning-dependent participants reporting regular IT, higher IT frequency, and higher scores on an opiate-like reactions to tanning scale. A valid tanning dependence screening tool is essential for researchers and physicians as a tanning-dependent diagnosis may facilitate a better understanding of tanning motivations and aid in the development of efficacious intervention programs.
Recent research has explored the idea that some patterns of tanning behavior may be dependent1- 7 by using a common alcohol screening questionnaire, the CAGE,8 or, alternatively, by adapting criteria for substance-related disorders from the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition, Text Revision) (DSM-IV-TR)9 modified to reflect UV light tanning (ie, sunbathing or indoor tanning [IT]).1,4,6,7Whereas data from the National Household Survey on Drug Abuse10 report prevalence rates for alcohol and any illicit drug combined as 2.6% to 9.3%, the modified CAGE and modified DSM report tanning dependence rates ranging from 12% to 55%.1,4,6,7,11Prevalence rates for dependence on alcohol and various drugs do differ. However, even in settings enriched for dependent behavior, such as bars,12 prevalence rates are not nearly as high as the tanning dependence rates reported. The high prevalence rates reported suggest that the current assessments tend to overidentify tanning dependence.
Feldman and others suggest that the mechanism for tanning dependence is most likely the release of endogenous opioids when the skin is exposed to UV radiation (see Nolan and Feldman5 for a review). It is probable that exploring tanning behavior by following the approach used in the DSM-IV-TR to categorize opioid use behaviors will lead to improved accuracy in the categorization of tanning dependence.
The Structured Interview for Tanning Abuse and Dependence (SITAD) is a tanning dependence assessment based on opioid use items adapted from the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID).13 The use of modified opioid SCID items was chosen specifically for good content and face validity in the measure. The self-administered structured interview format was chosen because this format has been demonstrated to achieve valid psychiatric categorization for opioid dependence in a previous study.14
Evaluation of the SITAD involved exploring differences in variables (ie, IT frequency, IT behavioral patterns, and scores on a scale measuring opiate-like reactions to tanning) that would theoretically be expected to differ among individuals exhibiting tanning abuse, those with tanning dependence, and those who do not meet the SITAD criteria for tanning abuse or dependence. We also expect that use of the SITAD will result in lower prevalence rates for tanning dependence than have been reported in previous studies.1,6,7

Stewart, Joanna L. "Glasgow's spatial arrangement of deprivation over time : methods to measure it and meanings for health." Thesis, University of Glasgow, 2016. http://theses.gla.ac.uk/7936/.
Full textAbstract:
Background: Socio-economic deprivation is a key driver of population health. High levels of socio-economic deprivation have long been offered as the explanation for exceptionally high levels of mortality in Glasgow, Scotland. A number of recent studies have, however, suggested that this explanation is partial. Comparisons with Liverpool and Manchester suggest that mortality rates have been higher in Glasgow since the 1970s despite very similar levels of deprivation in these three cities. It has, therefore, been argued that there is an “excess” of mortality in Glasgow; that is, mortality rates are higher than would be expected given the city’s age, gender, and deprivation profile. A profusion of possible explanations for this excess has been proffered. One hypothesis is that the spatial arrangement of deprivation might be a contributing factor. Particular spatial configurations of deprivation have been associated with negative health impacts. It has been suggested that Glasgow experienced a distinct, and more harmful, development of spatial patterning of deprivation. Measuring the development of spatial arrangements of deprivation over time is technically challenging however. Therefore, this study brought together a number of techniques to compare the development of the spatial arrangement of deprivation in Glasgow, Liverpool and Manchester between 1971 and 2011. It then considered the plausibility of the spatial arrangement of deprivation as a contributing factor to Glasgow’s high levels of mortality. Methods: A literature review was undertaken to inform understandings of relationships between the spatial arrangement of deprivation and health outcomes. A substantial element of this study involved developing a methodology to facilitate temporal and inter-city comparisons of the spatial arrangement of deprivation. Key contributions of this study were the application of techniques to render and quantify whole-landscape perspectives on the development of spatial patterns of household deprivation, over time. This was achieved by using surface mapping techniques to map information relating to deprivation from the UK census, and then analysing these maps with spatial metrics. Results: There is agreement in the literature that the spatial arrangement of deprivation can influence health outcomes, but mechanisms and expected impacts are not clear. The temporal development of Glasgow’s spatial arrangement of deprivation exhibited both similarities and differences with Liverpool and Manchester. Glasgow often had a larger proportion of its landscape occupied with areas of deprivation, particularly in 1971 and 1981. Patch density and mean patch size (spatial metrics which provide an indication of fragmentation), however, were not found to have developed differently in Glasgow. Conclusion: The spatial extent of deprivation developed differently in Glasgow relative to Liverpool and Manchester as the results indicated that deprivation was substantially more spatially prevalent in Glasgow, this was particularly pronounced in 1971 and 1981. This implies that exposure of more affluent and deprived people to each other has been greater in Glasgow. Given that proximal inequality has been related to poor health outcomes, it would appear plausible that this may have adversely affected Glasgow’s mortality rates. If this is the case, however, it is unlikely that this will account for a substantial proportion of Glasgow’s excess mortality. Further research into Glasgow’s excess mortality is, therefore, required.

Full textAbstract:
Prior to 1996, the prognosis of HIV disease was near-certain death; however, biomedical advancements in the past 20 years established HIV as a chronic manageable disease with a nearly normal life span. Recent advancements suggest the potential for a cure. One outcome of current medical treatments is that 50% of all HIV positive individuals are older (-?¥ 50years), and a substantial number of those individuals are long-term (-?¥ 20 years) survivors. Existing research Qualitative research has provided little insight about what older long-term HIV survivors believe about their disease circumstances and aging with the disease. A qualitative method in the phenomenological tradition was used to explore older long-term HIV survivors' notions about aging with HIV and an HIV cure. The self-regulation model of illness representations and the preventive and corrective, proactivity (PCP) model of aging with HIV disease for older adults guided the study. Using strategically placed flyers in HIV services environments, 12 older long-term HIV survivors volunteered to describe their beliefs about aging with HIV and an HIV cure. Participants' statements were entered into discrete cells in an electronic spreadsheet (Excel) and were coded, sorted, and categorized. The categories were sorted for commonality, and emergent themes and subthemes were identified. Older long-term HIV survivors believed they had few issues aging with HIV, expected to live a long time, and believed that finding a cure would have little effect on their lives. These research findings may be beneficial to healthcare providers and researchers who provide quality of life interventions and information to older adults living long-term with HIV who are concerned about aging, longevity, and a cure.

"A Measure of Cognitions Specific to Seasonal Depression: Development and Validation of the Seasonal Beliefs Questionnaire." Digital Commons @ East Tennessee State University, 2019. https://doi.org/10.1037/pas0000715.
Full textAbstract:
We introduce the Seasonal Beliefs Questionnaire (SBQ), a self-report inventory of maladaptive thoughts about the seasons, light availability, and weather conditions, proposed to constitute a unique cognitive vulnerability to winter seasonal affective disorder (SAD; Rohan, Roecklein, & Haaga, 2009). Potential items were derived from a qualitative analysis of self-reported thoughts during SAD-tailored cognitive-behavioral therapy (CBT-SAD) and subsequently refined based on qualitative feedback from 48 SAD patients. In the psychometric study (N = 536 college students), exploratory and confirmatory factor analyses pruned the items to a 26-item scale with a 5-factor solution, demonstrating good internal consistency, convergent and divergent validity, and 2-week test-retest reliability. In a known groups comparison, the SBQ discriminated SAD patients (n = 86) from both nonseasonal major depressive disorder (MDD) patients (n = 30) and healthy controls (n = 110), whereas a generic measure of depressogenic cognitive vulnerability (the Dysfunctional Attitudes Scale [DAS]) discriminated MDD patients from the other groups. In a randomized clinical trial comparing CBT-SAD with light therapy (N = 177), SBQ scores improved at twice the rate in CBT-SAD than in light therapy. Greater change in SBQ scores during CBT-SAD, but not during light therapy, was associated with a lower risk of depression recurrence 2 winters later. In contrast, DAS scores improved comparably during CBT-SAD and light therapy, and DAS change was unrelated to recurrence following either treatment. These results support using the SBQ as a brief assessment tool for a SAD-specific cognitive vulnerability and as a treatment target in CBT-SAD.

Full textAbstract:
Since the Human Immunodeficiency Virus (HIV) that causes Acquired Immune Deficiency Syndrome (AIDS) was discovered in the 1980s, the condom has scientifically proven to be the only technological device that can prevent transmission of the virus during sexual intercourse. This technical approach to the HIV has strongly emphasized that prevention is only possible if the condom is properly used. However, as a technological artifact the condom has shown that its use is laden with values. The question of values on condoms has brought in a heated debate on the moral justifications of its use. In Malawi, just as in other African countries, the Faith Community has rejected the Governmentsplea to promote condoms as the preventive measure against the virus.The Faith Community has emphasized on abstinence and mutual faithfulness as the only reliable means to the prevention of HIV/AIDS. The main argument from the Faith Community is that condoms promote promiscuity. Nevertheless, the Government agrees with the Faith Community on abstinence and mutual faithfulness, but still insists on condom use as a preventive measure against the virus. The Government argues that the condom is the only proven technical approach to the HIV prevention and therefore it should be promoted. T
he main purpose of this study is to attempt an ethical analysis of the arguments for and againstcondom use as the preventive measure against HIV. In this case, the study tries to analyse the Government and Faith Community stands on condoms. In relation to the arguments for and againstcondom use, the study also touches such areas as: the concept of rights and condom use, ethics of condom advertisement, African cultural values versus condom use and the implications of condom use on behaviour change. From the study, it has been argued that condoms should be promoted. The argument comes from that understanding that AIDS has plundered Africa than any war or disease in human history, and therefore, it needs to be stopped. In this case, such theories as, Utility, Love, Autonomy, Rights and umunthu moral conscience have been used to support the argument.

Full textAbstract:
Avian Influenza (AI) is a contagious viral zoonotic disease with great public health implications and negative socioeconomic impact (WHO, 2006a). The highly pathogenic avian influenza (HPAI) infection is transmitted from birds to man mostly through contact with contaminated poultry and objects (INFOSAN, 2005), hence people who come in contact with birds such as live bird sellers (LBS) are the more vulnerable population (WHO, 2006a). Inadequate knowledge of AI health risks and poor practice of AI preventive measures amongst LBS increases the risk of spread of the infection in both humans and animals.The aim of this study was to describe and quantify the knowledge and practice of LBS with regards to avian influenza health risks and preventive activities in Agege, an urban area in Lagos State, Nigeria.

Full textAbstract:
Introduction: Over 800,000 people die by suicide each year, and despite being a global public health issue, limited research exists exploring suicide risk assessment practices in emergency departments. The current thesis investigated emergency department suicide risk assessment practices and clinician experiences in Scotland, to develop guidance to inform the development of a clinically meaningful and feasible suicide risk assessment for these settings which is theoretically underpinned. Methods: A mixed-method triangulation approach was utilised. Two systematic reviews were conducted to update the risk and protective factor literature. This was followed by a national survey of suicide risk assessment practices in emergency departments. Fifty-one clinicians across 17 emergency departments participated, and six clinicians participated in follow-up semi-structured interviews to investigate their experiences, which were analysed using thematic analysis. Findings of the thesis were triangulated using the ‘following-a-thread' method, to develop guidance for informing the development of future risk assessment for use in emergency departments. Results: The systematic reviews identified emerging risk and protective factors including, sexual orientation and internet usage. The survey identified substantial variation in practice between emergency department clinicians. Only 35 (68.6%) participants reported using a suicide risk assessment tool. Importantly, variation was found not only across clinicians and departments, but also within departments, with clinicians based within the same department reporting differing risk assessment practices, indicating both inter- and intra-department suicide risk assessment practice differences. The qualitative analysis of clinician experience established four major themes (current experiences; components of suicide risk assessment; clinical decision-making; suicide risk assessment needs). Triangulation of findings developed recommendations for suicide risk assessment tools and training for emergency departments. Discussion: The risk and protective factor literature has evolved due to societal changes, and there is substantial variation in suicide risk assessment practices, both across and within emergency departments. Clinicians also find suicide risk assessment challenging. There is a need for consistent training, appropriate and helpful guidelines, and the improvement of risk assessment tools to improve practice. It is recommended that suicide risk assessment tools are developed to align to clinicians' needs, while taking into account research from the health domain and from related psychological research domains.

Full textAbstract:
As a result of global competition, companies within the automotive industry are required to improve their production systems to achieve sustainable and competitive production. To attain operational excellence, companies have adopted concepts like lean and World Class Manufacturing (WCM). In order to deliver, companies need to increase the availability and reliability of production equipment. This demands focus on both operational and strategic maintenance, and efficient equipment acquisition and management. The main objective of this thesis is to identify processes and success factors that are necessary for improved maintenance performance. By conducting a case study and by performing a literature review, the following has been studied: 1) how companies within the automotive industry work with maintenance and maintenance strategies, 2) implementation of maintenance strategies, and 3) new acquisition and spare parts management for maintenance. The results show that basic maintenance concepts and related terms are well defined in the literature. However, maintenance strategy is not unanimously defined. Results from the case study reveal that Professional Maintenance (PM) within WCM has been considered as a maintenance strategy. Furthermore, driving forces and obstacles for implementing maintenance strategies have been identified. The study also reveals that there is a strong link between maintenance performance, new acquisition and spare parts management.Den globala konkurrensen inom fordonsindustrin, har medfört krav på företag att effektivisera sina produktionssystem för att åstadkomma en hållbar och konkurrenskraftig produktion. Detta har resulterat i arbete enligt koncept som lean och World Class Manufacturing (WCM). För att kunna leverera behöver företag öka den tekniska tillgängligheten på utrustning. Detta i sin tur ställer ett ökat krav på både operativt och strategiskt arbete med underhåll, anskaffning och reservdelsstyrning. Målet med examensarbetet är att identifiera processer och faktorer som bidrar till ett förbättrat underhåll. Med hjälp av litteraturstudie och en fallstudie har följande studerats: 1) hur företag inom fordonsindustrin arbetar med underhåll och underhållsstrategier, 2) implementering av underhållsstrategier, och 3) nyanskaffning och reservdelsstyrning för underhåll. Resultat från litteraturstudier visar att det finns en enighet om att underhåll delas in i förebyggande och avhjälpande underhåll. Däremot, visar resultatet att det inte finns en enig definition av underhållsstrategi. Fallstudien visar att Professional Maintenance (PM) inom WCM betraktas som en underhållsstrategi. Som ett resultat har även ett antal drivkrafter och svårigheter som påverkar implementering av underhållsstrategier identifierats. Vidare visar resultatet att det finns ett starkt samband mellan underhåll, nyanskaffning och reservdelsstyrning.

Full textAbstract:
The behavior of repairable equipment is often modeled under assumptions such as perfect repair, minimal repair, or negligible repair. However the majority of equipment behavior does not fall into any of these categories. Rather, repair actions do take time and the condition of equipment following repair is not strictly "as good as new" or "as bad as it was" prior to repair. Non-homogeneous processes that reflect this type of behavior are not studied nearly as much as the minimal repair case, but they far more realistic in many situations. For this reason, the quasi-renewal process provides an appealing alternative to many existing models for describing a non-homogeneous process. A quasi-renewal process is characterized by a parameter that indicates process deterioration or improvement by falling in the interval [0,1) or (1,Infinity) respectively. This parameter is the amount by which subsequent operation or repair intervals are scaled in terms of the immediately previous operation or repair interval. Two equivalent expressions for the point availability of a system with operation intervals and repair intervals that deteriorate according to a quasi-renewal process are constructed. In addition to general expressions for the point availability, several theoretical distributions on the operation and repair intervals are considered and specific forms of the quasi-renewal and point availability functions are developed. The two point availability expressions are used to provide upper and lower bounds on the approximated point availability. Numerical results and general behavior of the point availability and quasi-renewal functions are examined. The framework provided here allows for the description and prediction of the time-dependent behavior of a non-homogeneous process without the assumption of limiting behavior, a specific cost structure, or minimal repair.Ph.

O impacto do Homem sobre a Terra, desde a extração intensiva dos recursos da natureza, extinção das espécies, emissões para o ar e água, consumo de energia e água até as mudanças climáticas do planeta, exigem medidas de contenção e preservação do meio ambiente. O futuro da humanidade é questionado e algo deve ser feito. Nesse contexto surge o conceito de desenvolvimento sustentável. Responsável pelo consumo de 40 a 50% da matéria-prima mundial, 12% da água e 40% das emissões de gases de efeito estufa, a indústria da construção possui importante papel na mitigação dos efeitos nocivos para o meio ambiente e capacidade de atingir altos índices de sustentabilidade. Dentro do ciclo de vida de uma edificação, a fase de Operação/Uso provoca grandes consequências ao meio ambiente e oferece grandes oportunidades de redução dos efeitos adversos. Nessa fase as atividades de manutenção predial acabam por ter seu valor reconhecido. As diversas estratégias de manutenção, em especial a manutenção preventiva baseada em condição, colaboram efetivamente para a durabilidade, desempenho e função da edificação e seus sistemas prediais. Procedimentos de manutenção estão associados à baixa qualidade do ar. A manutenção de sistemas de ar condicionado tem especial destaque devido às consequências para a saúde, bem-estar e produtividade dos ocupantes do edifício.Due to extensive extraction of natures resources, extinction of species, emission of gases into the atmosphere, water and power consumption, to climatic changes of the planet, mankinds impact on earth requires containment and preservation of the environment. The future of humanity is being questioned and something must be done. Responsible for the consumption of 40 to 50% of raw materials worldwide, 12% of water and 40% of emissions of gases into the atmosphere causing the greenhouse effect, the construction industry has an important role in alleviating the adverse impacts on the environment and the ability to achieve high sustainable levels. Within the lifecycle of a building, the phase of operation/use causes significant environmental consequences but also offers opportunities to alleviate adverse effects. In this phase, the value of building maintenance activities has been recognized. The various strategies for maintenance, principally preventive condition- based maintenance should collaborate effectively towards the durability, performance, function and systems of a building. Air-conditioning maintenance procedures are associated with poor air quality. The maintenance of air-conditioning systems has a special significance due to the effects on health, well-being and productivity of the occupants of the building.

Mestrado em Métodos Quantitativos para a Decisão Económica e EmpresarialO presente trabalho resulta de uma parceria entre o ISEG e a empresa PSE - Produtos e Serviços de Estatística, Lda., tendo por base a integração num projeto sob a forma de estágio. Baseia-se no desenvolvimento de modelos analíticos para a gestão da manutenção de um cliente da PSE, isto é, na análise e identificação de padrões e comportamentos de um conjunto de ativos de modo a conseguir determinar, de forma antecipada, a necessidade de serviços de manutenção. O estudo e a previsão de ocorrências de manutenção tem uma importância central para a redução de custos, a disponibilidade dos ativos e, consequentemente, a produção. Mais especificamente, o projeto prende-se com a análise de dados de manutenção na área hospitalar. Para desenvolvimento do projeto, foram disponibilizados dados de manutenção relativos ao ano de 2016, nomeadamente dados do inventário dos ativos, custos de manutenção, manutenções corretivas e preventivas que foram realizadas. O projeto foi dividido em duas fases: Preparação e exploração dos dados - com o objetivo de descrever e caracterizar estatisticamente os principais indicadores e potenciais associações na manutenção; Modelização - com o objetivo de criar um modelo que permita conjugar tanto as condições intrínsecas aos equipamentos, como o seu histórico de manutenção e intervenções e as suas condições atuais, por forma a identificar indicadores avançados de possibilidade de falha. Posteriormente haverá a implementação dos resultados, que corresponderá a implementação técnica do modelo preditivo no sistema do cliente.
The present master's thesis is the result of a partnership between ISEG and the company PSE - Produtos e Serviços de Estatística, Lda., and it was developed based on the integration of a six-month internship project. This internship subject is to develop analytical models for the management of the maintenance of one of PSE's customers by analysing and identifying patterns and behaviours of a set of assets in order to determine, in advance, the need for maintenance services. The study and prediction of maintenance needs is crucial to achieve costs reduction, assets availability and, consequently, production. More specifically, the project deals with the analysis of maintenance data in the hospital field. For the development of this project, maintenance data for the year 2016 were made available, namely data on assets inventory, maintenance costs and corrective and preventive maintenance measures that were performed. The project was divided into two parts: Setting and analysation of data - with the aim to describe and determine the main indicators and potencial associations in the maintenance; Modeling - with the aim to create a model that allows the association of the primary condition of the equipment, its maintenance history, past interventions and its current conditions, in order to identify advanced indicators of the chance of failure. Subsequently, the results will be implemented, which will correspond to the technical implementation of the predictive model in the customer system.

Följande avhandlingsarbete har utförts som en fallstudie på BillerudKorsnäs tillsammans med en litteraturstudie som har gett upphov till den teoretiska referensram som grundläggande lagt grunden för mätstrukturen Key Performance Indicators (KPI) utformad för underhållsorganisationen. Vidare har datainsamling i form av intern och extern benchmarking tillsammans med dokumentstudier, semistrukturerade intervjuer och strukturerade observationer genomförts för att få en fullständig redogörelse för den aktuella situationen i enlighet med riktlinjerna för examensarbete på högskolenivå. Examensarbetet täcker ämnet för underhållsteknik och syftar till att kartlägga underhållsstrategin för att kunna utforma en Key Performance Indikator (KPI: s) mätstruktur för BillerudKorsnäs. Examensarbetet ger därefter upphov till analysavsnittet som med stöd av den teoretiska referensramen redogör för det förbättringsförslag och framtida rekommendationer att belysa för ett underhåll och driftsäkerhet i världsklass. Studien framställer underhållsverksamheten med utgångspunkt från svensk standard och en ledande och eftersläpande mätetalsstruktur som vetenskapligt underlag. Detta har resulterat i en tydligt definierat underhållsstrategi med nyckeltalsprestationer för en underhållsorganisation där underhållstrategin är kopplad till företagets vision och strategi. Frågeställningen som är kopplad till problemformuleringen genomsyrar arbetet och handlar om att redogöra för hur man kan anknyta till underhållstrategin och redogöra för vilka KPI:er som skall redovisas, för att skapa en effektiv och produktiv underhållsverksamhet som arbetar i enlighet med de mål man satt upp på BillerudKorsnäs- Sulfatfabrik. Resultatet från det bedrivna arbetet visar att KPI-strukturen inte är i enlighet med den underhållstrategi BillerudKorsnäs på koncernnivå fastställt, vidare så påvisar nyckeltalen inte ett effektmätetal relevant för underhållsverksamheten och fabriksledningen. Genom förbättringsförslaget som föreslås tas en ny KPI-struktur fram som ger en mätbarhet till underhållsverksamheten och är kopplad till BillerudKorsnäs vision och strategi för ”Bästa arbetsätt” inom underhåll och driftsäkerhet i världsklass.The following thesis work has been carried out as a case study at BillerudKorsnäs together with a literature study which has given rise to the theoretical frame of reference which fundamentally laid the foundation for the Key Performance Indicators (KPI’s) measurement structure designed for the company. Furthermore, data collection in the form of internal and external benchmarking together with document studies, semi-structured interviews and structured observations has been carried out in order to get a complete view of the current situation as possible in accordance with the guidelines for scientific research approach. The research covers the subject area of maintenance technology and aims to map the maintenance strategy to be able to design a (KPI’s) measurement structure for BillerudKorsnäs maintenance organization. The thesis then gives rise to the analysis section which, with the support of the theoretical frame of reference, describes the improvement proposals and future recommendations to elucidate world-class maintenance and reliability. The study presents maintenance operations based on Swedish standards and “leading and lagging” measurement structure as a scientific basis. This has resulted in a defined metric structure with key performance measures for a maintenance organization where the maintenance strategy is connected to the company's vision and strategy. The question linked to the problem formulation permeates the research and is about explaining how to link to the maintenance strategy and describing which KPIs are to be reported, in order to create an efficient and productive maintenance organization that functions in accordance to the maintenance goals set on BillerudKorsnäs- Sulfatfabrik. The results of the conducted research show that the KPI- structure has not been established in accordance with BillerudKorsnäs' maintenance strategy at a cooperation level, furthermore, the key figures do not show an effect metric relevant to the maintenance operations and the factory management. The proposed improvement proposal proposes a new KPI- structure that provides measurability to the industrial maintenance operation and is symmetrical with BillerudKorsnäs vision and strategy for "Best working methods" in world-class maintenance and reliability.

Full textAbstract:
Idag finns det inte tillräckligt underhåll på de 15 svamp- och bakterietankar som finns på AstraZenecas vattenreningsverk i Gärtuna, Södertälje. Företaget använder sig av avhjälpande underhåll där de väntar på att tankarna ska gå sönder för att sedan laga dem. Reningsverket vill skapa en underhållsstrategi på tankarna genom att ta reda på om livslängden kan förlängas eller om, och i så fall när, utrustningen behöver renoveras, uppgraderas eller bytas ut. I litteraturstudier undersöktes underhållsstrategier, vattenreningsverk och olika tillståndskontroller. Besök gjordes för att få en bättre uppfattning om hur arbetet på vattenreningsverket ser ut idag. Intervjuer hölls med chefen för vattenreningsverket, en erfaren drifttekniker samt två externa företag som jobbar med underhåll. I resultatet framgår information om vilka fel som uppstått, vilka åtgärder som vidtagits samt vad det kostat. Det framgår även hur underhåll kan ske med olika externa parter och kostnader för detta. Två olika tillståndskontroller, digital röntgenskanning och penetrantprovning föreslås för att upptäcka fel på tankarna. Efter analys av resultatet har slutsatser om en ny underhållsstrategi kunnat dras. Rekommendationer om hur den kan implementeras och lämpligt intervall har tagits fram. AstraZeneca föreslås gå från ett avhjälpande till ett schemalagt tillståndsbaserat underhåll, där tillståndskontroller utförs var tredje, fjärde eller femte år beroende på personalens bedömning och de rekommenderas också att använda sig av externa resurser när det kommer till tvättning och tillståndskontroller av tankarna. Avhjälpande underhåll är omöjligt att planera och kommer med vår lösning att minimeras. Schemalagt tillståndsbaserat underhåll som vi rekommenderar kommer resultera i en mycket enklare planering och oväntade kostnader likväl som oväntade stopptider kommer undvikas. Regelbundet underhåll kommer troligtvis resultera i att tankarnas livslängd ökar vilket bidrar till en bättre hållbarhet och man slipper köpa in nya tankar.Today, there is not enough maintenance on the 15 fungal and bacterial tanks found at AstraZeneca's wastewater treatment plant in Gärtuna, Södertälje. The company uses a maintenance strategy where they wait for the tanks to fail and then fix them. The treatment plant wants to create a maintenance strategy for the tanks by finding out if the life span can be extended or if, and if so, when the equipment needs to be renovated, upgraded, or replaced. With literature studies maintenance strategies, wastewater treatment plants and various condition investigations, were analysed. The visits were made to get a better idea of how the work at the wastewater treatment plant looks like today. Interviews were held with the head of the water treatment plant, an experienced operating technician and two external companies working on maintenance. The result shows information about what errors occurred, what measures were taken and what it cost. It also shows how maintenance can be done with various external sources and costs for this. Two different condition investigations, digital x-ray scanning and penetrant testing are suggested to detect errors in the tanks. After analysing the results, conclusions about a new maintenance strategy could be drawn. Recommendations on how it can be implemented, and an appropriate interval have been developed. AstraZeneca should go from corrective to scheduled condition-based maintenance, where condition investigations are performed every three, four or five years depending on the staff's assessment and they could make use of external sources when it comes to washing and condition investigations of the tanks. Corrective maintenance is impossible to plan and our solution will minimize this. Scheduled condition-based maintenance that we recommend will result in a much simpler planning where unexpected costs as well as unexpected downtime will be avoided. Regular maintenance will probably result in an increase in the service life of the tanks, which contributes to better durability and they will not have to buy new tanks.

Full textAbstract:
Power flow (PF) control can increase the utilization of the transmission system and connect lower cost generation with load. While PF controllers have demonstrated the ability to realize dynamic PF control for more than 25 years, PF control has been sparsely implemented.
This research re-examines PF control in light of the recent development of fractionally-rated PF controllers and the incremental power flow (IPF) control concept. IPF control is the transfer of an incremental quantity of power from a specified source bus to specified destination bus along a specified path without influencing power flows on circuits outside of the path.
The objectives of the research are to develop power system operation and planning methods compatible with IPF control, test the technical viability of IPF control, develop transmission planning frameworks leveraging PF and IPF control, develop power system operation and planning tools compatible with PF control, and quantify the impacts of PF and IPF control on multi-decade transmission planning.
The results suggest that planning and operation of the power system are feasible with PF controllers and may lead to cost savings. The proposed planning frameworks may incent transmission investment and be compatible with the existing transmission planning process. If the results of the planning tool demonstration scale to the national level, the annual savings in electricity expenditures would be $13 billion per year (2010$). The proposed incremental packetized energy concept may facilitate a reduction in the environmental impact of energy consumption and lead to additional cost savings.

Full textAbstract:
Trois types de dommages non encore survenus, dont la distinction repose sur la probabilité d'occurrence, peuvent être identifiés : le dommage futur, le dommage possible et le dommage hypothétique. Le droit de la responsabilité extracontractuelle ne comporte pas de dispositions relatives au traitement de ces types de dommage. Ce sont les magistrats qui ont, de toute pièce, construit le traitement du dommage non encore survenu, à partir des textes existants. Eu égard à sa source, celui-ci demeure tantôt nébuleux tantôt incohérent. C'est pourquoi, il convient de remettre de l'ordre. Plus qu'un traitement, ce sont en réalité trois traitements que nous avons pu recenser et qui sont appelés à varier selon le type de dommage non encore survenu auquel la victime est exposée. Tandis que le premier traitement réside dans la prévention du dommage non encore survenu, le deuxième consiste, quant à lui, en la réparation des préjudices actuels résultant de l'exposition à un dommage non encore survenu. Le troisième et dernier traitement réside dans la réparation ou dans l'évaluation anticipée de la réparation des préjudices finaux qui pourraient résulter d'un dommage non encore advenu. Des variations de régime illustrent, en outre, la différence de probabilité d'occurrence du dommage entre le dommage futur, le dommage possible et le dommage hypothétique pour chacun de ces traitementsThree types of loss or damage can be identified according to the probability of such loss or damage occurring: future loss or damage, possible loss or damage and hypothetical loss or damage. Extracontractual liability does not include any provisions relating to the treatment of this type of loss or damage. It is the judges who have determined how to treat loss or damage that has not yet occurred, based on existing law. As a result, treatment remains nebulous at best and incoherent at worst which is why the question needs to be addressed. Rather than one type of treatment, we have identified three types of treatment that vary according to the type of loss or damage that has not yet occurred. Unlike the first treatment is based on the prevention of the loss or damage that has not yet occurred, the second type of treatment consist of compensation for actual loss or damage resulting from exposure to loss or damage that has not yet occurred. The last type of treatment is based on compensation or anticipated evaluation of final loss or damage as the result of the loss or damage that has not yet occurred. Variations in the treatment applied also illustrate the difference in the probability of occurrence between future loss or damage, possible loss or damage and hypothetical loss or damage

Taiwan has the typical island economy, without abundant natural resources. Diligent people, small and medium enterprises, Export Processing Zones all contribute to the economy miracle in the 1980's and 1990's. Without doubt, the important fundamental infrastructures also built a strong foundation. All the above help the growth of the international trade, making a small island like Taiwan shine. With the world economic growth and globalization, and the fast progress of aeronautics and astronautics industry which brings larger carrying capacity, higher gas efficiency, faster and more stable aircrafts, air transport is able to deliver many different types of products to all over the world with at a lower cost, in addition to the advantages it already had such as speed and not limited by physical barriers of the terrain. The definition of air transport is that, when shipping from point A to point B, the whole way or a section utilizes aircraft transport. This study limits the range to the international air cargo transport between countries. However, the products are shipped through land transport from the production plant to the Air Cargo Terminals to store, out of storage, packed and shipped to the destination, and then shipped to the customers from the warehouse by trucks. In this process, cargo operation is the stage among the whole transport process where problems are most likely to occurto the products. Especially in recent years, Taiwan is seeking industrial upgrading and produces many High Tech and High Value products, which resulted inmany customer complaints and cases of claims caused by cargo damage. 4 Therefore, this study focuses on the cases of past years where problems occur to the products, in the Taiwan Air Cargo Terminals of Taoyuan International Airport, and also touches on the issues of claims and how it affects the storage capacity of customers. Most important of all, this study seeks to provide solutions to those problems, hoping to benefit the air cargo operation. In the future, it is advised for other scholars to study further into grocery air transport, priority cargo processing, and the prevention of operation errors, in order to improve the quality of cargo operation of our country to the level ofthe world.

This paper focuses on the preventive and control measure of abnormal voltage profile on the secondary bus. The investigation is to design a Smart Monitoring System (SMS), which is installed on the rising circuit of On-Load Tap-Changer (OLTC). While the bus is under the abnormal situation, OLTC will react in a certain time and the situation will be recorded. Until approaching to a rated reaction number, the SMS will warn the corresponding duty officers by an alert signal and then automatically cuts off the abnormal circuit. The corresponding officers can manually adjust and control the abnormal voltage profile. The SMS prevents people from under the dangerous rising voltage situation, helps to maintain power quality, and avoids the risk of disputes and reparations between people and the power company. This SMS has been adopted as one of optional preventive measures of abnormal voltage profile on the bus in the administrative area of Kaohsiung Extra High Voltage (EHV) substation.

Full textAbstract:
We consider a class of periodic preventive maintenance (PM) optimization problems, for a single piece of equipment that deteriorates with time or use, and can be repaired upon failure, through corrective maintenance (CM). We develop analytical and simulation-based optimization models that seek an optimal periodic PM policy, which minimizes the sum of the expected total cost of PMs and the risk-averse cost of CMs, over a finite planning horizon. In the simulation-based models, we assume that both types of maintenance actions are imperfect, whereas our analytical models consider imperfect PMs with minimal CMs. The effectiveness of maintenance actions is modeled using age reduction factors. For a repairable unit of equipment, its virtual age, and not its calendar age, determines the associated failure rate. Therefore, two sets of parameters, one describing the effectiveness of maintenance actions, and the other that defines the underlying failure rate of a piece of equipment, are critical to our models. Under a given maintenance policy, the two sets of parameters and a virtual-age-based age-reduction model, completely define the failure process of a piece of equipment. In practice, the true failure rate, and exact quality of the maintenance actions, cannot be determined, and are often estimated from the equipment failure history.
We use a Bayesian approach to parameter estimation, under which a random-walk-based Gibbs sampler provides posterior estimates for the parameters of interest. Our posterior estimates for a few datasets from the literature, are consistent with published results. Furthermore, our computational results successfully demonstrate that our Gibbs sampler is arguably the obvious choice over a general rejection sampling-based parameter estimation method, for this class of problems. We present a general simulation-based periodic PM optimization model, which uses the posterior estimates to simulate the number of operational equipment failures, under a given periodic PM policy. Optimal periodic PM policies, under the classical maximum likelihood (ML) and Bayesian estimates are obtained for a few datasets. Limitations of the ML approach are revealed for a dataset from the literature, in which the use of ML estimates of the parameters, in the maintenance optimization model, fails to capture a trivial optimal PM policy.
Finally, we introduce a single-stage and a two-stage formulation of the risk-averse periodic PM optimization model, with imperfect PMs and minimal CMs. Such models apply to a class of complex equipment with many parts, operational failures of which are addressed by replacing or repairing a few parts, thereby not affecting the failure rate of the equipment under consideration. For general values of PM age reduction factors, we provide sufficient conditions to establish the convexity of the first and second moments of the number of failures, and the risk-averse expected total maintenance cost, over a finite planning horizon. For increasing Weibull rates and a general class of increasing and convex failure rates, we show that these convexity results are independent of the PM age reduction factors. In general, the optimal periodic PM policy under the single-stage model is no better than the optimal two-stage policy. But if PMs are assumed perfect, then we establish that the single-stage and the two-stage optimization models are equivalent.text

Research background: Growing along with the aging and aged citizens in the society since 1993, percentage of the citizens that aged over 65 had reached a new record of 11.9% of the population in Taiwan by the end of 2014. Accompanied with such an aging and aged trends, Taiwan nationals suffered with multiple chronic diseases. Taken the case of diabetic mellitus as example, there were around 10% of the people suffered with DM, and it was found in one of every four senior citizens who aged over 65. Literature suggested that chronic patients exposed to a higher risk of blindness 25 times over the ordinary patients because of retinopathy and macular degeneration. Literature suggested that sufficient and ongoing lutein supply can effectively prevent eyes from the threats of excessive ultraviolet and blue lights. It had been confirmed that intake lutein daily can sharply reduce the risk of macular degeneration. To assure a quality life for the chronic patients in the lengthy life expectancy, continuous intake the lutein supplement to protect eye’s function is essential. Based on the health belief model, this research explored how the chronic patients perceived threats of eye diseases, and how do they perceive the benefits and barriers of taking lutein supplement as a protection measure, and how these variables affected the lutein intake behavior. A structured questionnaire based on the health belief model was used as research instrument to collect data. Store customers who had completed a transaction were invited to complete the questionnaire. 452 valid responses were duly collected for proper analyses. This study employed SPSS for windows 20.0 to conduct statistical works, of which included descriptive, independent t-test, One-way ANOVA, Pearson correlation analysis, and multiple regressions to accomplish the study purposes. The respondents had 1.96 sources of health information, of which television program and the internet were the two major sources. Pharmacy was the main access outlet for general OTC medicine (77.95%) and lutein supplement (65.92%), followed by the drugstores (37.42%, 34.74%). The levels of severity varied along with the respondent’s education, occupation, and income factors; levels of perceived lutein benefit varied by their household registration; whilst the lutein consumption behavior varied by the respondent’s gender, age, household. Two independent variables of susceptibility (r=.138, p=.004) and perceived benefit (r=.422, p=.000) had significant correlation with lutein intake behavior, whereas the rest two variables of severity (r=.052, p=.288) and perceived barrier (r=.055, p=.359), were not significantly correlated. Four independent variables of the health belief model explained 18.1% of variance of the lutein consumption behavior. Test result indicated that the perceived benefit of lutein was the major predictor (β=.419), whereas the effects from other variables, susceptibility, severity, and perceived lutein barriers were not significant. The study brought an important reference for the nutritional supplement industries and the health promotion institutes when planning and implementing eye-care and lutein consumption campaigns.

Dissertação de Mestrado em Ambiente, Saúde e Segurança.Dada a actividade comercial do Grupo SATA, o risco de barotraumatismo é possível durante o serviço de voo. Algumas das consequências são problemas de saúde para estes tripulantes, que por sua vez contribuem para baixas prolongadas e custos socioeconómicos para a SATA Internacional, e acima de tudo, para o colaborador. Para melhor compreender a severidade desta lesão, foi desenhado um estudo retrospectivo analítico e uma análise estatística com dados referentes a 137 participações de acidentes de trabalho de barotraumatismo, no período compreendido entre 2006 e 2011, ocorridos na SATA Internacional. A análise dos resultados revelou um aumento progressivo da incidência de BT. Ao longo dos 6 anos, e como previsto pelas pesquisas, notou-se que os barotraumatismos na SATA Internacional ocorreram, maioritariamente, aquando das descidas da aeronave (95,4% dos casos). As assistentes de bordo com menos de um ano de serviço são as que correm maior risco, sendo as profissionais com mais casos de barotraumatismo (OR: 9,05; RR:7,42; IC: 95%). Sabemos ainda que, indivíduos com 33 anos de idade foram os mais afectados, e que em termos de lesões, tanto o ouvido direito como o esquerdo foram igualmente afectados. Dito isto, este estudo reúne dados que explicam como ocorre o barotraumatismo, seus condicionantes, impactos, faculta medidas preventivas e correctivas para prevenção de novos casos na SATA Internacional, já que se pretendia fornecer as ferramentas necessárias para reduzir as ocorrências de acidentes de trabalho de barotraumatismo nesta companhia. Deste modo, este projecto tenta recomendar as medidas necessárias para garantir a saúde deste pessoal navegante de cabine e pessoal navegante técnico, já que desempenham funções que os colocam em maior risco de sofrerem um barotraumatismo comparativamente a qualquer outro tipo de profissão dentro da SATA Internacional.
ABSTRACT: Given the commercial activity of Grupo SATA, the risk of barotrauma is considered possible during flight service. Some of the consequences can result in health problems in these crew members, which can contribute to prolonged absences, which result in social and economic costs for the company, and above all, for the employee. In order to better understand the seriousness of this wound, a retrospective study was designed, and a statistical analysis with data concerning 137 accidents of barotrauma in the period between 2006 and 2011, that occurred in SATA International. The analysis of these results showed a progressive increase in the incidence of barotrauma. Over these 6 years, and as presented by this research, it was noted that barotraumas in SATA International, occurred mostly during the descents of the aircraft (95.4% of cases). The flight attendants with less than one year of service are the mostly at risk, being the professionals with more barotrauma cases (OR: 9.05; RR: 7.42; IC: 95%). We also know that, individuals with 33 years of age were the most affected, and concerning the injuries, both the right and left ear were also affected, but with little difference between them. Thus said, this study gathers data explaining the occurrence of barotrauma, its agents, impacts, provides preventive and corrective measures to prevent new cases of barotrauma on SATA International, as it was meant to offer the necessary tools that would allow a better management in reducing these accidents in this company. In this sense, this project recommends the necessary measures to guarantee the health of these flight personnel, as they play roles that place them at greater risk of suffering a barotrauma compared to any other profession, in this company.

Full textAbstract:
This work examines sexual behavioural change and the likely predisposing factors in the era of HIV/AIDS among young adults in Uganda and South Africa. It explores the potential role of young adults' self-perceived risk of HIV infection in sexual behavioural decisions regarding adoption of safe sex practices, in particular 'use of condoms' and 'limiting number of sexual partners '. This work further recognises that Uganda and South Africa are countries with social, cultural, economic, and political contexts, which contexts have been described by many as inextricably linked with sexual behaviour, and which often determine the choices young adults make regarding sexual activity. These are therefore examined. In order to achieve this, a rigorous examination and analysis of self-perceived risk of HIV/AIDS in relation to societal factors was done to determine which variables of the two categories best explains sexual behaviour. This is placed in the context of young female adults between the ages of 15 to 24 in Uganda and South Africa. The formulation of this study, which places emphasis on examining the potential role of self-perceived risk of HIV/AIDS as a predisposing factor for sexual behavioural change, and in Uganda and South Africa is based on a number of aspects as highlighted below: • That both Uganda and South Africa at one point or another were and/or are faced with high prevalence levels of HIV/AIDS; • That both have and/or are yet to be faced with high mortality, which is HIV/AIDS related and such profound consequences will/or have had inadvertent effects on individual, both socially and economically. In some respects, this has also affected individual perceptions regarding HIV infection; • Recognition that the progression of HIV/AIDS in Uganda was much faster than in South Africa, and this meant higher prevalence, higher mortality rates, which then triggered both government and non-governmental response towards preventing further spread. Since these factors are beginning to emerge in South Africa, one therefore asks the question as to whether the pandemic will take similar trends as those reported in Uganda. This would also enable the identification of similarities and differences in the likely determinants of sexual behavior considering these countries have different backgrounds; • In both countries, education programmes have been rigorous and that the level of awareness is at a point that would enable sexual behavioural change to occur; • A recognition that in Uganda, as shown in a number of reports and existing literature, the prevalence of HIV has declined and for this reason, it has become imperative to try and examine the likely factors leading to reduced HIV/AIDS prevalence, and to compare with what is happening in South Africa. This would enable the examination of any possible lessons that could be learnt in the reduction of the prevalence in South Africa. In the quest to achieve the set goals, a number of steps were undertaken which included looking at available literature and more importantly analysing two sets of Demographic Health Survey (DHS) data. The South Africa Demographic Health Survey of 1998 (SADHS) and the Ugandan Demographic Health Survey (UDHS) of 2000/1. All young female adults between the ages of 15 to 24 were selected from both data sets. 3,229 and 4,559 young female adults were selected in Uganda and South Africa respectively leading to a total sample size of 7,688. Findings showed that self-perceived risk of HIV/AIDS was one of the factors that did impact on sexual behaviour. This was more prominent in Uganda and less so in South Africa. Other factors found to affect sexual behaviour included age of respondent, socio-cultural and to a small extent, socio-economic factors. The conclusion that can be drawn from this work shows clearly that self-perceived risk of HIV/AIDS is an important factor determining sexual behaviour, but also shows that some societal variables are important. Therefore, in the face of HIV/AIDS and with increased levels of number of people experiencing deaths due to AIDS, selfperceived risk of HIV/AIDS is a factor worth considering when looking at sexual behaviour. As part of the recommendations, education programmes yet to be formulated should take into account the effect of HIV and AIDS on sexual behavioural change.Thesis (M.A.)-University of Natal, Durban, 2003.

This work explores the application of a complementary indicator of the analytical process, the average number of patient samples containing unacceptable analytical error due to undetected out-of-control error condition (ANPTE). The implementation of this additional indicator in clinical laboratory daily routine led to the implementation of a stand-alone software application which enables the integration of this indicator on the clinical lab management support system for quality control purposes.
The quality of analytical processes of clinical laboratories is of fundamental importance namely: to perform diagnostics, monitor patient’s clinical evolution and their responsiveness to treatment of several diseases, as well as for screening the presence of diseases in apparently healthy individuals. The quality verification check is done based on control samples that test the operational procedures and the validity of the tests. A correct quality control must be implemented to allow statistical treatment of results of control samples. The main goal is to ensure the quality of laboratory results by monitoring analytical system’s operations for error detection, at the earliest possible stage in the process. That is the earliest possible detection of a flaw which has negative implications in the system’s performance hence decreasing the risks meaningful clinical variation which are known to have a negative impact on medical decisions.
The evolution of clinical laboratories has led to greater automation of processes radically changing the way of implementation of the analysis, impacting on how quality is managed in this sector. A performance measurement focused on patient analysis results and frequency-dependent events of quality control is more suitable for nowadays laboratories which operate in continuous flow mode. The application of this additional indicator of performance evaluation, supported by a software tool integrated in daily routine, will potentially result in value added on quality management of clinical laboratories.
