Full textAbstract:
The Velum, Oropharynx, Tongue base and Epiglottis (VOTE) classification on drug-induced sleep endoscopy (DISE) is used widely for obstructive sleep apnea (OSA) syndrome, though research into comparative physical examinations with VOTE on DISE is still limited. The aim of this study was to evaluate the relationship between the findings of physical examinations and DISE in patients with OSA. Fifty-five patients with OSA were enrolled in this retrospective study. All of the patients received clinical explorations including a Brodsky classification, a modified Mallampati score (MMS), a modified Friedman’s staging system, and a Muller’s test. Drug-induced sleep endoscopy was further evaluated in the operating room. There were significant relationships between Brodsky classification, modified Friedman’s staging system, Muller’s test and oropharynx collapse during DISE (p < 0.05). Brodsky classification, MMS, modified Friedman’s staging system and retropalatal lateral-to-lateral (L–L) collapse of Muller’s test were significantly correlated with VOTE count (p < 0.05). The concordance between VOTE under DISE and Brodsky classification or modified Friedman’s staging system was moderate. In contrast, the concordance between VOTE under DISE and MMS or Muller’s test was slight. The study revealed that Brodsky classification and Friedman staging had a significant relationship with DISE on the velum and oropharynx, but the level of tongue base is uncertain between DISE and MMS. Correlation of awake evaluation of tongue base is still not correlated to the DISE findings. Pre-treatment evaluation of DISE is still warranted.

Background and Purpose: Quantification of hepatic virtual iron content (VIC) by using Multidetector Dual Energy Computed Tomography (DECT) has been recently investigated since this technique could offer a good compromise between accuracy and non-invasiveness for liver iron content quantification. The aim of our study is to investigate differences in VIC at different DECT time points (namely baseline and arterial, venous and tardive phases), identifying the most reliable and also exploring the underlying temporal trend of these values. Materials and Methods: Eleven patients who underwent DECT examination and were characterized by low liver fat content were included in this retrospective study. By using the Syngo.via Frontier–DE IronVNC tool, regions of interest (ROI) were placed on the VIC images at 3 hepatic levels, both in left and right liver lobes, at each DECT time point. Friedman’s test followed by Bonferroni-adjusted Wilcoxon signed-rank test for post-hoc analysis was performed to assess differences between DECT timepoints. Page’s L test was performed to test the temporal trend of VIC across the 4 examined timepoints. Results: For both liver lobes, Friedman’s test followed by Bonferroni-adjusted Wilcoxon signed-rank test revealed that VIC values differed significantly when extracted from ROIs placed at the 4 different timepoints. The Page’s L test for multiple comparison revealed a significant growing trend for VIC, from baseline acquisition to the fourth and last time point post-contrast agent injection. Conclusions: The extraction of hepatic VIC in healthy subjects was found to be significantly influenced by the DECT time point chosen for the extrapolation of the VIC values.

Full textAbstract:
For the comparison of more than two independent samples the Kruskal-Wallis H test is a preferred procedure in many situations. However, the exact null and alternative hypotheses, as well as the assumptions of this test, do not seem to be very clear among behavioral scientists. This article attempts to bring some order to the inconsistent, sometimes controversial treatments of the Kruskal-Wallis test. First we clarify that the H test cannot detect with consistently increasing power any alternative hypothesis other than exceptions to stochastic homogeneity. It is then shown by a mathematical derivation that stochastic homogeneity is equivalent to the equality of the expected values of the rank sample means. This finding implies that the null hypothesis of stochastic homogeneity can be tested by an ANOVA performed on the rank transforms, which is essentially equivalent to doing a Kruskal-Wallis H test. If the variance homogeneity condition does not hold then it is suggested that robust ANOVA alternatives performed on ranks be used for testing stochastic homogeneity. Generalizations are also made with respect to Friedman’s G test.

Background: The aim of this study was to examine the effect of dietary education on glycemic control in patients with any type of diabetes at four-week and two-year follow-ups. Methods: A two-year prospective study was conducted in three phases: before, four weeks after, and two years after an educational program. The participants were patients diagnosed with diabetes who were receiving insulin or oral hypoglycemics and who attended the Diabetes Clinic of the General County Hospital Našice, Croatia to receive their treatment. The questionnaire and educational program were created for the purpose of this study. Measurements were made (fasting blood glucose, glycated hemoglobin, body mass index, blood pressure, knowledge test) at baseline, four weeks and two years after education. Results: A total of 109 participants took part in the study, of which 56 (51.4%) were on insulin therapy and 53 (48.6%) were on oral therapy, after two years, 78 (72%) subjects were followed up with. There was no control group. At the two-year follow-up, participants with insulin therapy had significantly higher glycated hemoglobin (Mann–Whitney U test, p = 0.035). Significant differences were observed in fasted blood glucose (Friedman’s test, p = 0.001), diastolic pressure (Friedman’s test, P = 0.018), and glycated hemoglobin (Wilcoxon test, p < 0.001) between Phase 1 and Phase 3. Conclusions: Education has a positive effect on adherence to recommended diet and glycemia regulation in diabetes patients after four-week follow-ups. However, after two years, participants showed a decrease in adherence to recommended diet and increased glycemia.

Abstract Objectives Nearly 50% of children with a mental health concern do not receive treatment. Child Psychiatry Access Programs like Behavioral Health Integration in Pediatric Primary Care (BHIPP) address regional shortages of mental health treatment access by providing training and consultation to primary care providers (PCPs) in managing mental health concerns. This study assessed PCPs’ comfort with mental health practices to inform expansion of BHIPP services. Methods Pediatric PCPs in 114 practices in three rural regions of Maryland were recruited to participate in a survey about their comfort with mental health practices and access to mental health providers for referral. Descriptives, Friedman’s test, and post hoc pairwise comparisons were used to examine survey responses. Results Participants were 107 PCPs. Most respondents were physicians (53.3%) or nurse practitioners/physician’s assistants (39.3%). Friedman’s test, χ2(7)= 210.15, p<.001, revealed significant within and between-group differences in PCP comfort with mental health practices. Post hoc pairwise comparisons indicated greater comfort providing mental health screening and referrals compared to prescribing psychiatric medications, providing psychoeducation or in-office mental health interventions. A Wilcoxon-signed rank test showed significantly more respondents agreed they could find a therapist than a psychiatrist in a timely manner, Z= −5.93, p<.001. Conclusions Pediatric PCPs were more comfortable with providing mental health assessment and referrals than treatment. However, PCPs reported difficulty finding therapists and psychiatrists for their patients. Findings underscore the need for longitudinal training to increase PCP comfort with mental health treatment. Additionally, strategies such as telepsychiatry are needed to address the disproportionate need for child psychiatrists.

Full textAbstract:
This paper mainly deals with how kernel method can be used for software defect prediction, since the class imbalance can greatly reduce the performance of defect prediction. In this paper, two classifiers, namely, the asymmetric kernel partial least squares classifier (AKPLSC) and asymmetric kernel principal component analysis classifier (AKPCAC), are proposed for solving the class imbalance problem. This is achieved by applying kernel function to the asymmetric partial least squares classifier and asymmetric principal component analysis classifier, respectively. The kernel function used for the two classifiers is Gaussian function. Experiments conducted on NASA and SOFTLAB data sets usingF-measure, Friedman’s test, and Tukey’s test confirm the validity of our methods.

Purpose The purpose of this paper is to improve the Siloam Hospitals’ (SHs) patient satisfaction index (PSI) and overcome Indonesia’s geographical barriers. Design/methodology/approach The topic was selected for reasons guided by the Institute of Healthcare Improvement virtual breakthrough series collaborative (VBSC). Subject matter experts came from existing global quality development in collaboration with sales and marketing, and talent management agencies/departments. Patient satisfaction (PS) was measured using the SH Customer Feedback Form. Data were analysed using Friedman’s test. Findings The in-patient (IP) department PSI repeated measures comparison during VBSC, performed using Friedman’s test, showed a statistically significant increase in the PSI, χ2 = 44.00, p<0.001. Post hoc analysis with Wilcoxon signed-rank test was conducted with a Bonferroni correction applied, which resulted in a significant increase between the baseline and action phases (Z=3.317, p=0.003) between the baseline and continuous improvement phases (Z=6.633, p<0.001), and between the action and continuous improvement phases (Z=3.317, p=0.003), suggesting that IP PSI was continuously increasing during all VBSC phases. Like IP PSI, the out-patient department PSI was also continuously increasing during all VBSC phases. Research limitations/implications The VBSC was not implemented using a control group. Factors other than the VBSC may have contributed to increased PS. Practical implications The VBSC was conducted using virtual telecommunication. Although conventional breakthrough series might result in better cohesiveness and commitment, Indonesian geographical barriers forced an alternative strategy, which is much more cost-effective. Originality/value The VBSC, designed to improve PS, has never been implemented in any Indonesian private hospital group. Other hospital groups might also appreciate knowing about the VBSC to improve their PSI.

Full textAbstract:
Icons have been widely utilized to describe and promote COVID-19 prevention measures. The purpose of this study was to analyze the preference and subjective design features of 133 existing icons associated with COVID-19 prevention measures published by the health and medical organizations of different countries. The 133 icons represent nineteen different function names, such as “Wash Hands” and “Wear Face Mask”. A total of 57 participants were recruited to perform two different tests: ranking test and subjective rating test. The ranking test was conducted to elicit the preference ranking of seven icon designs representing each function name. It was followed by a subjective rating test using 13 semantic scales on the two most preferred icons to analyze their perceived quality. Spearmen correlation was applied to derive the possible correlations between users’ rankings and the semantic scales, and Friedman’s test was also performed to determine the true difference between ranking in terms of each semantic scale to provide a fully meaningful interpretation of the data. Generally, findings from the current study showed that the image presented in the icon is the key point that affects the icons’ perceived quality. Interestingly, Spearman’s correlation analysis between preference ranking and semantic scales showed that vague–clear, weak–strong, incompatible–compatible, and ineffective–effective were the four strongest semantic scales that highly correlated with the preference ranking. Considering the significant relationships between the semantic distances and the functions, images depicted in an icon should be realistic and as close as possible to its respected function to cater to users’ preferences. In addition, the results of Spearman’s correlation and Friedman’s test also inferred that compatibility and clarity of icon elements are the main factors determining a particular icon’s preferability. This study is the first comprehensive study to evaluate the icons associated with the COVID-19 prevention measures. The findings of this study can be utilized as the basis for redesigning icons, particularly for icons related to COVID-19 prevention measures. Furthermore, the approach can also be applied and extended for evaluating other medical icons.

Sixteen high-level athletes (mean age 14.5 years) from the city of Belo Horizonte participated in the study. Athletes were monthly evaluated by means of the field test using the System of Tactical Assessment in Soccer – FUTSAT, which allowed the characterization of the incidence of tactical principles and place of action in the game field, as well as the percentage of positive offensive and defensive tactical principles. Data were analyzed by Friedman’s test (incidence of tactical principles and place of the action) and one-way ANOVA for repeated measures (percentage of positive tactical principles), adopting significance level of p<0.05. Results showed differences in the incidence of offensive and defensive units tactical principle, as well as the place of actions in the game field. An improvement in offensive and defensive tactical behavior was also observed throughout the season.

Convolutional neural networks (CNNs) are one of the deep learning techniques that, due to the computational advance of the last few years, have leveraged the area of computer vision, allowing substantial gains in the most varied classification problems, especially those involving digital images. In this context, this paper aims to propose a methodology for the classification of multiple pathologies related to different plant species. Initially, this methodology involved the image processing and the generation of ten new databases, varying between 50 and 66 classes with greater representation. After training the models (VGG16, RestNet101v1, ResNet101v2, ResNetXt50, and DenseNet169), a comparative study was conducted based on widely used classification metrics, such as test accuracy, f1-score, and area under the curve. To attest the significance of the results, Friedman’s nonparametric statistical test and two post-hoc procedures were performed, which demonstrated that ResNetXt50 and DenseNet169 obtained superior performances when compared with VGG16 and ResNets.

The COVID-19 pandemic has prompted the Indonesian government to implement a distance learning system. Changes and uncertainties might deteriorate mental health, especially in female adolescents who were initially prone to experiencing stress based on their developmental stage and gender. This study aims to determine the effectiveness of stress management training with Online Group Cognitive Behavioral Therapy approaches in reducing stress and developing adaptive coping strategies. A total of 8 participants (ages 14-15) were recruited online with the purposive sampling technique. Changes in stress levels and coping strategies were tested using Friedman’s ANOVA test. There was a significant reduction in stress that continued until 1-month follow-up and increased adaptive coping strategies after the intervention (post-test). Participants also reported positive changes in cognition and emotion, including increased belief about their ability to handle stress in the future. However, there was no statistically significant reduction in a maladaptive coping strategy. Additional factors, such as individual differences and interactions with the environment influenced the intervention's effectiveness.

Abstract The extensive use of commercial activated carbon as an adsorbent for the purification of industrial effluent is not economical for small and medium-sized enterprises due to its high operational cost. This study was carried out to compare the adsorptive capacity of bentonite clay and activated corn cob (“BC” and “ACC”) for the removal of lead (II) and nickel (II) ions from an aqueous solution. The results obtained from the characterization of the BC and ACC are pH: 7.43 and 6.74; moisture content: 36.45kg/kg and 12.10kg/kg, and bulk density: 1.243g/ml and 1.162g/ml, respectively. Normality tests using the coefficient of skewness indicated that the set of data was not normally distributed. An analysis of variance (ANOVA) test conducted using Friedman’s 2-way ANOVA test indicated p values of 0.0253 against an alpha value of 0.05, which indicates significance. The Friedman results indicated significance with respect to the varied dosages, initial concentrations, and contact time. The effect of the adsorbent was not significant. The adsorption isotherms were analysed using the Langmuir, Freundlich, and Temkin isotherms. Most research studies have shown that adsorption experiments performed using most low-cost materials tend to follow the Freundlich adsorption isotherm, but the results of this experimental study proved that activated corn cob and bentonite clay performed better with the Temkin adsorption isotherm with 0.879 ≤ R2 ≤ 0.917 for the bentonite clay and 0.9572 ≤ R2 ≤ 0.99 for the activated corn cob respectively. The study revealed that these materials are good adsorbents that can be used for the removal of lead (II) and nickel (II) ions from an aqueous solution.

Full textAbstract:
Although the issue of corporate culture has been taken over and addressed in the literature from various perspectives, there are very few researchers about the role of leadership and motivation in it, respectively very few researchers have addressed them as important components of the international company’s corporate culture. The present paper aims to point out that leadership and motivation can be perceived as important aspects of the international company’s corporate culture. The object of the investigation was an international company (situated in Italy) and its five subsidiaries (situated in Italy, Czech Republic, Germany, and Turkey). As the main research method, there was chosen the method of the questionnaire survey, which was attempted by all the company’s employees (totally 270 respondents). The questionnaire was divided into three separate, but logically related parts—leadership, motivation, and corporate culture, and submitted to two groups of respondents—the company’s management and its employees. In total 11 hypotheses were formulated and further evaluated by the methods of Pearson Chi-square Test, Fisher’s Exact Test, Cramer’s V coefficient, Kendall rank correlation coefficient, Eta coefficient, Spearman coefficient, Mann–Whitney U test and Wilcoxon W statistics, Kruskal–Wallis test, and Friedman’s test. The results of the research have proven that leadership and motivation are important parts of the corporate culture.

This randomized clinical trial aimed to evaluate the endodontic retreatment techniques influence using reciprocating files and ultrasonic inserts in relation to the incidence, intensity, and postoperative pain duration. Forty-six patients were randomly assigned into two groups: Reciprocant files (RC group); or the Clearsonic Ultrasonic Insert (CL group;). Participants were asked to report the incidence, duration, and postoperative pain intensity using a visual analog scale (VAS) at 24, 48 and 72 h after retreatment. Fisher’s exact test was used to compare the two methods used regarding postoperative pain. The Mann-Whitney test was used to compare pain intensity, and Friedman’s test was used to assess the time effect on pain intensity. Finally, ordinal logistic regression analysis was used to assess the odds ratio for pain occurrence at a significance level of 5%. The postoperative pain incidence was significantly lower in the CL group in all experimental periods. Comparing the two techniques, pain intensity was significantly lower in the CL group after 24 and 48 h. For the RC group, pain intensity was significantly greater at 24 h compared with the other periods. The technique used in endodontic retreatment can influence postoperative pain.

Full textAbstract:
The present paper is focused on the issues of private labels, their establishment, perception and preference by selected groups of respondents, namely consumers under the age of 25 and also inhabitants of selected V4 countries (Slovakia, Hungary and Czech Republic). An anonymous questionnaire survey was chosen as the main research method. A total of 3038 respondents aged under 25 participated—1064 respondents were from Slovakia, 973 from Hungary and 1001 from Czech Republic. This research method was subsequently supplemented with selected statistical methods evaluated in the XL Stat statistical program, SAS Enterprise Guide 7.1 and SAS 9.4, where hypotheses were examined by Pearson’s Chi-Square Test, Mantel–Haenszel Chi-square test, Cramer’s V contingency coefficient, Pearson’s correlation coefficient, Friedman’s test, Kruskal–Wallis test, Correspondence analysis and Phi Coefficient. The results of the survey can be perceived more than positively as most of the respondents declared that they knew the concept of private labels; more than 80% of respondents buy them either regularly or sporadically; just over 32% of respondents explicitly prefer them in their purchases and in terms of the perception of the quality, almost 75% of respondents think the quality of private label products is comparable to that of traditional brands.

The coronavirus disease-2019 (COVID-19) pandemic is an ongoing concern that requires research in all disciplines to tame its spread. Nine classification algorithms were selected for evaluating the most appropriate in predicting the prevalent COVID-19 transmission mode in a geographic area. These include; multinomial logistic regression, k-nearest neighbour, support vector machines, linear discriminant analysis, naïve Bayes, C5.0, bagged classification and regression trees, random forest, and stochastic gradient boosting. Five COVID-19 datasets were employed for classification. Predictive accuracy was determined using 10-fold cross validation with three repeats. The Friedman’s test was conducted and the outcome showed the performance of each algorithm is significantly different. The stochastic gradient boosting yielded the highest predictive accuracy, 81%. This finding should be valuable to health informaticians, health analysts and others regarding which machine learning tool to adopt in the efforts to detect dominant transmission mode of the virus within localities.

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n1p62 The aim of this study was to compare the collective tactical behavior between numerically balanced and unbalanced small-sided soccer games. Eighteen male soccer players (mean age 16.4 years) participated in the study. Polar coordinate analysis was performed using positional data obtained with a 15-Hz GPS device. Collective variables including length, width, centroid distance (average point between teammates), and length per width ratio (LPWratio) were collected. Data were analyzed using Friedman’s test. The results showed greater length and width values in 4vs.3 games, while a higher LPWratiowas observed in 3vs.3+2 games compared to the other configurations. In games with an additional player (4vs.3), ball circulation and the increase in effective game space were alternatives to overcome the more concentrated defensive systems near the goal. On the other hand, 3vs.3+2 games allowed more actions in the length axis and a fast reach of the opponent’s goal.

The purpose of this study was to analyze both male and female physical education teacher attitudes toward cultural pluralism and diversity. Participants (N = 433) were adapted physical education specialists, physical education generalists, and teacher candidates. The research method was a descriptive cross-sectional survey (Fraenkel & Wallen, 1990). Data were collected using a modified version of the Pluralism and Diversity Attitude Assessment survey (Stanley, 1997). Mann-Whitney U tests showed no significant differences in attitude scores between teachers and teacher candidates. However, women’s attitude scores were significantly higher than men’s. Further Friedman’s ANOVA test showed statistical differences on the survey’s constructs for gender and professional status. Post hoc analysis indicated that the groups scored significantly higher on the construct, Value Cultural Pluralism than Implement Cultural Pluralism. This means teachers generally valued cultural diversity, but struggled to implement culturally responsive pedagogy. In conclusion, physical educators may need better preparation to ensure cultural competence.

AbstractBoth in literature and philosophy it is assumed that the beginning of post-modernity coincides with the end of the so-called grand narrative. Referring to Philippe Lacoue-Labarthe’s last book L’“Allégorie”, one could claim that since then, literary (re)presentation manifests itself as essentially ‘chronic’ and nonallegorical. Moreover, in the wake of Thomas Friedman’s The World is Flat the twenty-first century is often referred to as an all-visible flat world. This flatness, however, both extends and challenges the postmodern end of the grand narrative. After all, a world without reverse might be particularly suitable for an allencompassing story. This seems to be the conclusion drawn by the remarkable and comparable recent novels of three Flemish literary writers. Putting to the test existing ideas of literary presentation of post-modernity, they return to the grand narrative while at the same time subscribing to the main characteristics of contemporary literature.

Full textAbstract:
Maropitant, an antagonist of neurokinin-1 (NK-1) receptors, blocks the pharmacological action of substance P on the central and peripheral nervous systems. The objective of this study was to compare the antinociceptive and cardiorespiratory effects of the continuous intraoperative infusion of maropitant with ketamine and lidocaine in female dogs undergoing unilateral radical mastectomy. Twenty-four female dogs were used and were divided randomly into two groups (n = 12). The GLK group received ketamine bolus (1.0 mg/kg), lidocaine bolus (1.5 mg/kg), and continuous infusion of ketamine and lidocaine (10 mcg/kg/min and 50 mcg/kg/min), respectively; the GLKM group received the same anesthetic protocol combined with maropitant bolus (1.5 mg/kg/IV) and continuous infusion of maropitant (100 mcg/kg/h). Continuous infusion was initiated at the start of surgery and was maintained until 1 hour postoperatively. Pain was evaluated in the postoperative period using four scales and a digital analgesimeter. Data were analysed using analysis of variance, Student's t-test, Mann–Whitney test, and Friedman’s test ( P < 0.05). Kaplan–Meier curves were compared using the log-rank test. The results indicated lower pain scores, better survival curves with a lower number of patients requiring rescue analgesia, and lower peripheral sensitization, in the GLKM group than in the GLK group. It was concluded that the coadministration of maropitant with ketamine and lidocaine had an adjuvant effect with minimal cardiorespiratory effects and effective analgesia, improving pain management and patient comfort.

Full textAbstract:
The aim of this study was to evaluate the mixture of Calcium Sulfate and Plasma Rich in Growth Factors (CaSO4 + PRGF) as a bone-graft substitute in extracted mandibular third molar (MTM) alveoli during a 4-month period. Bilateral MTM extractions were performed in 10 patients (18–25 years) at the Oral-Surgery-Clinic of the Universidad Autónoma de Yucatán (UADY). A CaSO4 + PRGF mixture was placed in the right alveolus (Experimental Group (EG)) and a natural blood clot in the left (Control Group (CG)). Monthly X-ray controls were performed using a gray scale to measure Bone Regeneration (BR). A non-parametric Sign Test was used to evaluate Radiopacity/Bone Regeneration (Ro/BR) over 4 months, and a Friedman’s non-parametric test was used for intra-group analysis over these months. The study was approved by the Centro de Investigaciones Regionales (Dr. Hideyo Noguchi, UADY Bioethics Committee, ID 0026-2015). Using a non-parametric test of the sign, the EG showed significant difference of Ro/BR between groups p = 0.002 (p < 0.05). Significant differences were observed in all quadrants and areas p = 0.002 (p < 0.05) except in area A in month 4 (p = 0.016), which could be explained by its being the closest to native bone. EG CaSO4 + PRGF showed a higher degree of bone regeneration compared to CG.

Full textAbstract:
Abstract Introduction Few studies investigated the mechanical properties of orthodontic wires on ceramic brackets associated the ligatures. Objective This study aimed to compare the load-deflection of orthodontic wires with round section of 0.016” made of stainless steel (SS), nickel-titanium (NiTi) and glass fiber-reinforced polymer composite (GFRPC). Material and method Sixty specimens obtained from 10 sectioned pre-contoured arches (TP Orthodontics), were divided into 3 groups of 20 according to each type of material (1 esthetic-type wire and 2 not esthetic) and length of 50 mm. The methodology consisted of a 3-point bending test using esthetic ceramic brackets (INVU, TP Orthodontics, Edgewise, 0.022”x 0.025”) as points of support. The tensile tests were performed on a mechanical test machine, at a speed of 10 mm/min, deflection of 1 mm, 2 mm and 3 mm. Friedman’s Non Parametric Multiple comparisons test was used (P<0.05). Result The nickel-titanium wire presented smaller load/ deflection compared with stainless steel. GFRPC wires had lower strength values among all groups evaluated (P<.05). The steel wire showed permanent deformation after 3 mm deflection, NiTi wire demonstrated memory effect and the esthetic type had fractures with loss of strength. Conclusion It can be concluded that steel wires have high strength values, requiring the incorporation of loops and folds to reduce the load / deflection. NiTi and GFRPC wires produced low levels of force, however the esthetic wire was shown to fracture and break.

Purpose: To compare the effect of two treatment options in mandibular Kennedy class I cases regarding oral health related quality of life (OHRQoL) and the biting force, removable partial dentures retained by either precision attachment (PA-RPD) or clasps (C-RPD)Materials and methods: The study included 32 partially edentulous patients which 16 patients received PA-RPD (OT Cap Attachment) and 16 patients received C-RPD. All the patients in both groups were asked to fill the OHRQoL questionnaire after 1 week (baseline), 3 months, 6 months and 12 months after prosthesis insertion. Biting force was measured using the i-load Star Sensor one week, 3 months, 6 months and 1 year after partial denture insertion for all patients in both groups. Statistical analysis comprised Mann Whitney U test, Friedman’s test, Dunn’s test and Chi-square test.Results: The results of OHRQoL revealed that at the baseline, 3 months and 6 months the PA-RPD showed statistically significant lower mean total OHIP-14 score than the C-RPD. However, after 12 Monthes , there was no statistically significant difference between total OHIP-14 scores in the two groups. Concerning the biting force there was no statistically significant difference between the two groups.Conclusion: Within the limitations of this study it was concluded that the OHRQoL of both the PA-RPD and the C-RPD was comparable after 12 months. Similarly the biting force was the same for both treatment options.

Full textAbstract:
Introduction: Postural defects and accompanying dysfunctions are one of the greatest existing health problems. It is necessary to define factors responsible for the formation of incorrect body posture and strive to eliminate or modify them. The aim of the study was to determine changes in trunk positioning depending on the way of carrying a small handbag (the bag weighing 2.7 kg). Materials and methods: The study comprised 32 volunteers aged 21.75±2.00 years. The ZEBRIS Pointer system was used to test the body posture. The Statistica v13 program was applied for data compilation. Normality of distribution regarding variables was tested with the Shapiro-Wilk test. Differences between repeated measures were estimated using ANOVA, Friedman’s rank test and post hoc tests. The level of statistical significance was α=0.05. Results: Placing the bag on one shoulder significantly increased thoracic kyphosis, while wearing the bag diagonally across the trunk caused a significant increase in both thoracic kyphosis and lumbar lordosis. Other observed changes concerned the balance of the trunk in the sagittal plane, the position of the shoulder blades, symmetry of shoulder position and pelvic rotation. Conclusions: Carrying even a small load in the form of a bag significantly changes quality of body posture. Furthermore, changes in body posture depend on the way of carrying the load. Wearing the bag diagonally across the trunk is not better than carrying it asymmetrically on one shoulder.

Full textAbstract:
The intention of this study was to find out if external focus of attention, steering the archers’ focus on distal movement effects, will provide better shooting accuracy expressed as higher number of 10 points and higher overall result. The subject sample was consisted of 10 elite male archers, with average age 25.8 years. The sample of variables was derived from observed characteristics of entities in different shooting conditions. A measure of arrow distance from the center of the target face was used in order to estimate shooting precision. The testing consisted of three different shooting conditions: C1- free focus of attention, C2 – internal focus of attention and C3 – external focus of attention. The analysis showed that the highest results were obtained in condition of externally oriented focus of attention (C3), and the lowest results in condition of internally oriented focus of attention (C2). Friedman’s ANOVA did not show statistical differences between the conditions, but they were found between C2 and C3 in afterwards administered Wilcoxon’s test (p=0.047).

Full textAbstract:
This study aimed to analyze the effects of using bioceramic clothing on the 10 km running performance. Ten healthy young males (age 27.9 ± 4.2 years; height 1.8 ± 0.1 m; body mass 73.0 ± 7.5 kg; body mass index (BMI) 23.5 ± 2.3 kg·m2 and body fat 19.3 ± 4.2 %) volunteered to participate in the study. The participants visited the track for three 10 km performances under different conditions: bioceramic clothes (CER), placebo (PLA) and personal clothes (C). Test order was randomized and subjects were blind to the intervention condition, except for the C. Friedman’s test or ANOVA for repeated measures were used to compare the conditions. Minimal detectable change and Effect Size were also calculated. Results: No statistical differences were found. Minimal detectable change analysis suggested a “Possible” reduction in time for the CER condition (C – 52.3 ± 4.1; PLA – 53.1 ± 5.0; CER 51.4 ± 3.8 minutes). Lactate concentration analysis showed a faster removal when subjects were using bioceramic clothes. DOMS was rated as “Possible” higher in the CER condition, and the Session Rate of Perceived Exertion (RPESession) was also higher in that condition, rated as “Small” through Cohen’s Effect Size analysis (C – 425.7 ± 74.8; PLA – 426.6 ± 87.5; CER – 440.1 ± 42.5 A.U.). Conclusion: Results suggest that the use of bioceramic clothes might improve running performance. Further studies are necessary to determine ideal dosage such as time of use and factors influencing absorption.

Full textAbstract:
Background. Deep brain stimulation of the subthalamic nucleus (STN-DBS) is a surgical treatment to reduce the “off” state motor symptoms of Parkinson’s disease (PD). Postural instability is one of the major impairments, which induces disabilities of activities of daily living (ADLs). The effectiveness of STN-DBS for postural instability is unclear, and the effect of rehabilitation following STN-DBS has remained uncertain. Objective. The purpose of this study was to examine changes in balance ability, gait function, motor performance, and ADLs following 2 weeks of postoperative rehabilitation in PD patients treated with STN-DBS. Methods. Sixteen patients were reviewed retrospectively from February 2016 to March 2017. All patients were tested in their “on” medication state for balance and gait performance using the Mini-Balance Evaluation Systems Test (Mini-BESTest) and the Timed “Up and Go” (TUG) test before the operation, after the operation, and during the discharge period. The UPDRS motor score (UPDRS-III) and Barthel Index (BI) were assessed before the operation and during the discharge period. Rehabilitation focused on muscle strengthening with stretching and proactive balance training. Friedman’s test and the post hoc Wilcoxon’s signed-rank test were used to analyze the balance assessments, and ANOVA and the post hoc Tukey’s test were used to analyze gait performance. The significance level was p<0.05. Results. During the discharge period, the Mini-BESTest and TUG were significantly improved compared with the preoperative and postoperative periods (p<0.05). There were no differences between preoperative and postoperative periods in the Mini-BESTest (p=0.12) and TUG (p=0.91). The BI and motor sections of the UPDRS did not differ significantly between the preoperative and postoperative periods (p=0.45, p=0.22). Conclusion. The results of this study suggest that postoperative rehabilitation improves balance and gait ability in patients with PD treated with STN-DBS.

Academic achievement of students does not depend only on school, environmental factors and teacher characteristics, but also on the level of home involvement. This study therefore sought to establish the extent of parental school involvement for students’ improved academic achievement in Awka South Local Government Area of Anambra State. The descriptive survey design was used for this study, with six (6) research questions guiding the study. The population for the study comprised 417 public secondary school teachers from which a sample of 125 teachers using simple random sampling technique. The instrument for data collection was a researcher designed, structured questionnaire which was duly validated by experts in educational management and measurement and evaluation. The questionnaire was tested for reliability using test-retest method. The tool for correlation was the Pearson Product Moment Correlation and this yielded a co-efficient of 0.82. Data collected was analysed using mean and standard deviation statistics to answer the 6 research questions while ANOVA with Friedman’s Test was used to test for significant difference in the six indices of parental involvement. The findings show among others that teachers perceive that parents in Awka South Local Government Area effectively communicate with school and coach their children for improved academic achievement to a moderate extent. There was no significant difference in the teacher’s perception of parental involvement based on the six indices of involvement. Based on the findings, the researchers recommended among others, that parents and the school use social media and other devices to communicate more effectively with the school for improved students’ academic performance.

Full textAbstract:
Purpose This paper aims to describe two enhancements of the variable neighbourhood search (VNS) algorithm to solve efficiently the minimum interference frequency assignment problem (MI-FAP) which is a major issue in the radio networks, as well as a well-known NP-hard combinatorial optimisation problem. The challenge is to assign a frequency to each transceiver of the network with limited or no interferences at all. Indeed, considering that the number of radio networks users is ever increasing and that the radio spectrum is a scarce and expensive resource, the latter should be carefully managed to avoid any interference. Design/methodology/approach The authors suggest two new enhanced VNS variants for MI-FAP, namely, the iterated VNS (It-VNS) and the breakout VNS (BVNS). These two algorithms were designed based on the hybridising and the collaboration approaches that have emerged as two powerful means to solve hard combinatorial optimisation problems. Therefore, these two methods draw their strength from other meta-heuristics. In addition, the authors introduced a new mechanism of perturbation to enhance the performance of VNS. An extensive experiment was conducted to evaluate the performance of the proposed methods on some well-known MI-FAP datasets. Moreover, they carried out a comparative study with other metaheuristics and achieved the Friedman’s non-parametric statistical test to check the actual effect of the proposed enhancements. Findings The experiments showed that the two enhanced methods (It-VNS) and (BVNS) achieved better results than the VNS method. The comparative study with other meta-heuristics showed that the results are competitive and very encouraging. The Friedman’s non-parametric statistical test reveals clearly that the results of the three methods (It-VNS, BVNS and VNS) are significantly different. The authors therefore carried out the Nemenyi’s post hoc test which allowed us to identify those differences. The impact of the operated change on both the It-VNS and BVNS was thus confirmed. The proposed BVNS is competitive and able to produce good results as compared with both It-VNS and VNS for MI-FAP. Research limitations/implications Approached methods and particularly newly designed ones may have some drawbacks that weaken the results, in particular when dealing with extensive data. These limitations should therefore be eliminated through an appropriate approach with a view to design appropriate methods in the case of large-scale data. Practical implications The authors designed and implemented two new variants of the VNS algorithm before carrying out an exhaustive experimental study. The findings highlighted the potential opportunities of these two enhanced methods which could be adapted and applied to other combinatorial optimisation problems, real world applications or academic problems. Originality/value This paper aims at enhancing the VNS algorithm through two new approaches, namely, the It-VNS and the BVNS. These two methods were applied to the MI-FAP which is a crucial problem arising in a radio network. The numerical results are interesting and demonstrate the benefits of the proposed approaches in particular BVNS for MI-FAP.

Background. Proto-oncogenes, particularly ras, may not only affect cell proliferation but also contribute to angiogenesis by influencing both proangiogenic and antiangiogenic mediators. The aim of this study was to investigate whether any relationship exists between ras expression and angiogenesis during diethylnitrosamine- (DEN-) induced experimental liver fibrosis.Materials and Methods. Liver cirrhosis was induced in rats by intraperitoneal injections of DEN. The animals were sacrificed 2 weeks after the last administrations and a hepatectomy was performed. Masson’s trichrome staining was used in the evaluation of the extent of liver fibrosis. The vascular density in portal and periportal areas was assessed by determining the count of CD34 labeled vessel sections. For quantitative evaluation of H-ras expression, in each section positive and negative cells were counted.Results. In fibrotic group H-ras expression was higher than that in nonfibrotic group and was more widespread in cirrhotic livers. Friedman’s test showed that there was a significant correlation between H-ras expression and VD (P<0.01).Conclusion. The results of this descriptive study reveal that H-ras expression gradually increases according to the severity of fibrosis and strongly correlates with angiogenesis.

Research, development of new biotechnological methods, diagnostic tests, confirmation of results, and reinvestigations are possible because of the availability of well-preserved living organisms maintained without any changes. Cryopreservation is a simpler, more reliable and long-term stable method for culture maintenance. Storage temperature and composition of the suspending vehicle are factors that affect the viability of mycobacterial strains. Three vehicles and three storage temperatures were evaluated to define a suitable cryoprotective medium for the preservation of Mycobacterium bovis strains. Colonies of sixteen M. bovis isolates were used to prepare the suspensions, which were then added to three vehicles: sterile 0.85% saline solution (SS), Middlebrook 7H9 broth (7H9), and Middlebrook 7H9 broth with sodium pyruvate (7H9p) replacing glycerol. Aliquots of these suspensions were frozen by three different methods, directly in the -20°C freezer, directly in the -80°C freezer, and at -196°C by immersion in liquid nitrogen (LN). The frozen aliquots were thawed at room temperature after 45, 90 and 120 days. Mycobacterial viability was assessed by counting the living cells on plates of Stonebrink medium before and after the freezing procedure. Storage at -20°C exhibited a lower recovery of M. bovis compared to storage at -80°C (Dunn’s test, p=0.0018) and LN (Dunn’s test, p=0.0352). There was no statistically significant difference between storage at -80°C and in LN (Dunn’s test, p=0.1403), yet -80°C showed better results than LN. All three suspending vehicles showed no statistically significant difference in terms of viability (Friedman’s test, p=0.7765). Given the low loss proportion of 5% during storage at -20°C and the high cost equipment required for storage at -80°C and LN, we recommend storage at -20°C or -80°C, when this is available, for preservation of M. bovis field strains.

ABSTRACT 2017-253 Few standardised frameworks are designed to assess the full range of oil spill preparedness activities, from plan development, implementation, equipment, training, exercises, and response sustainability. This paper analyses the international practice of oil spill preparedness measures and compares them to Swedish practice. Friedman’s test and Dunn’s post-test have been used to compare the RETOS™ evaluation scores of Finland, Russia, Latvia, Lithuania, Poland, Germany, Denmark, and Norway to Sweden. The United States is examined as an external reference. The RETOS™ programme is an Excel tool developed for the International Oil Spill Conference 2008. It is a guide for industry and governments to assess their level of oil spill response, planning, and preparedness management in relation to established criteria, and is intended for international best management practices. Swedish oil spill preparedness is shown to be comparable to the Baltic Sea regional practice. The Swedish RETOS™ evaluation score is 69%, compared to the average 73.1% of the examined countries. A statistical difference exists between Sweden and both Norway and the United States. Swedish oil spill preparedness is comparable to the Baltic Sea Region countries despite: not having a National Contingency Plan, not using the Tiered Preparedness and Response concept, nor having adopted an Incident Management System. This suggests that these concepts are not essential for a functioning preparedness regime, although Sweden instead has a system serving the same function. However, it also questions what effect implementing these concepts would have on Swedish preparedness.

Full textAbstract:
Challenges to measuring students’ attitudes toward statistics remain despite decades of focused research. Measuring the expectancy-value theory (EVT) Cost construct has been especially challenging owing in part to the historical lack of research about it. To measure the EVT Cost construct better, this study asked university students to respond to items using both a Likert-type response and an Evaluative Space Grid (ESG)-type response. ESG items enable bivariate responses in a single item and permit distinguishing among two different types of neutral attitudes: indifferent and ambivalent. This pilot study evaluates the appropriateness of ESG-type items for measuring the EVT Cost construct by analyzing student response patterns to ESG-type items and comparing them with Likert-type items. Validity evidence is documented using descriptive statistics and graphs, correlations among items, and a trinomial hypothesis test. Internal consistency reliability indices are also reported. Friedman’s Test is used to compare the average response times for items of different types. Results indicate that students can meaningfully respond to ESG-type items in ways that are similar to their Likert-type responses, that students respond to ESG-type items quicker with more practice, and that distinguishing among indifferent and ambivalent attitudes seems appropriate for the EVT Cost construct. These findings suggest that ESG-type items may provide new insights not possible with Likert-type items but also that more research should be conducted to better understand their advantages and disadvantages within statistics education.

Latar Belakang: Ototoksik merupakan salah satu efek samping kanamisin yang sulit dihindari. Ototoksisitas kanamisin ditandai dengan gangguan pendengaran sensorineural yang progresif dan sering irreversible dimulai dari frekuensi lebih dari 8000 Hz yang akhirnya akan mengenai frekuensi yang lebih rendah jika terapi dilanjutkan. Tujuan: Penelitian ini bertujuan untuk mengetahui pengaruh pemberian kanamisin pada pasien tuberkulosis multi drug resistance (TB MDR) terhadap munculnya ototoksik dengan pemeriksaan audiometri. Metode: Penelitian observasional longitudinal dengan pendekatan cohort ini mengevaluasi fungsi pendengaran sebelum dan setelah pemberian kanamisin pada pasien TB MDR. Pemeriksaan fungsi pendengaran menggunakan audiometri nada murni. Kanamisin adalah aminoglikosida pilihan pada pasien dengan TB MDR yang akan diberikan secara injeksi intramuskular. Hasil: Uji Friedman’s menunjukkan ditemukan perubahan yang bermakna pada hasil pengukuran audiometri pada frekuensi tinggi antara pasca injeksi kanamisin bulan pertama, kedua, hingga kelima dengan hasil pengukuran sebelum terapi (p>0,05). Diagnosis ototoksisitas menggunakan kriteria American-Speech-Language-Hearing-Association (ASHA) dapat dideteksi sejak bulan pertama pemberian kanamisin (25%). Kesimpulan: Ada hubungan antara kejadian ototoksik dengan pemberian kanamisin pada penderita TB MDR. Telah terjadi ototoksisitas sejak injeksi kanamisin bulan pertama yang dideteksi dengan menggunakan pemeriksaan audiometri, dan bermakna secara statistik. Introduction: Ototoxicity is one of common side effects of kanamycin which is hard to avoid. Ototoxicity can be detected by a progressive and irreversible high frequency sensorineural hearing loss that can further affect low frequency if the therapy is continued. Kanamycin is the drug-of-choice for TB MDR through intramuscular (IM) injection. Purpose: This study aims to determine whether kanamycin can cause ototoxicity in patient with MDR TB by using audiometry examination. Method: An observational longitudinal study with cohort design, evaluating patient’s hearing threshold before and after kanamycin IM injection once per month using pure tone audiometry. Result: A significant alteration in high pitch before and after injection of kanamycin was revealed with Friedman’s test (p<0.05) for hearing threshold using pure tone audiometry. Furthermore, using American Speech-Language-Hearing Association (ASHA) the diagnosis of ototoxicity can be established since the first month of kanamycin injection in 25% of the subjects, and also 25% in the second month of injection. Conclusion: There is a significant connection between ototoxicity with kanamycin injection in MDR TB patients, statistically proven. The ototoxicity can happen since the first month of injection, which can be detected using pure tone audiometry.

Full textAbstract:
The increased number of energy efficiency requirements of the European Union has increased the renovation rate of apartment buildings. The external thermal insulation composite system (ETICS) is often used to upgrade the façade. However, the construction process shortcomings very often cause defects shortly after completion. This paper develops a technical–economic relevance assessment model of the onsite degradation factors for better quality assurance in an SME. The model quantifies the technical significance of the degradation factors along with the future repair costs. The technical severity of 103 factors is evaluated by 12 experts, and the data is validated with the Friedman’s test. The occurrence ratio, detectability, and latency period are foreseen by five experts and validated with the Delphi technique. The results of the three sample simulations emphasize the activities during substrate preparation and application of adhesive as well as a base coat with reinforcement mesh. The application of a finishing coat and installation of insulation plates have less relevance. It is recommended to upskill the craftsmen in regard to working with mixtures as the shortcomings are covered simultaneously and the failure detection period is short. The measures to protect against external weather effects are recommended due to their relatively high impact. Half of the shortcomings appear during the first two years.

Abstract Introduction Blood is a biological material with high potential of infectious transmission in dental environments, including herpes simplex, hepatitis and AIDS. Aim To investigate the efficacy of luminol in detecting blood in endodontic files before and after the sterilization process. Material and method Luminol was used to investigate the presence or absence of traces of blood tissue in 50 endodontic files, visible to naked eye or not, after performing endodontic treatment and after the cleaning/sterilization process. The results obtained were tabulated and statistically analyzed by using the Friedman’s test at a significance level of 5% (p<0.05). Result By naked eye, it was found that 31/50 files showed no trace of blood, 8/50 showed a slight presence of blood and 11/50 showed a considerable presence of blood after endodontic treatment. After the use of luminol, however, 16/50 endodontic files showed no trace of blood, 19/50 showed a slight presence of blood and 15/50 showed a considerable presence of blood. After the cleaning and sterilization process, no blood was detected in the files. Conclusion It was concluded that the luminol solution is effective in detecting blood tissue in endodontic files as well as in validating the cleaning/sterilization process.

Full textAbstract:
Dexmedetomidine (DEX) alone, or combined with butorphanol (BUT), may be administered by constant rate infusions (CRIs) in standing horses. This blinded, randomised, crossover study in six healthy adult horses aimed to determine the sedative and cardiopulmonary effects of DEX (dexmedetomidine (3.5 µg/kg+5 µg/kg/hour CRI) and DEX/BUT (dexmedetomidine (3.5 µg/kg+3.5 µg/kg/hour CRI) and butorphanol (20 µg/kg+24 µg/kg/hour CRI)). Head height above ground (HHAG), ataxia, responses to tactile/auditory stimuli and cardiopulmonary variables were recorded before, at 5/15/30/60/90 minutes and after CRIs terminated (15/30/60 minutes). Repeated measures analysis of variance with Tukey-Kramer test were used for cardiopulmonary values (mean±SD) and HHAG reduction (per cent), and Friedman’s and Dunn’s for non-parametric data (P<0.05). Maximum HHAG reductions of 54 per cent (DEX) and 58 per cent (DEX/BUT) occurred at 15 minutes, with ataxia for 15 minutes in both treatments. Responses to stimuli were reduced for 30 minutes in both treatments, and auditory up to 60 minutes in DEX. Cardiopulmonary effects typical of α2-agonists were observed, with no differences between treatments. At the doses and rates reported here, both regimens provided clinically sufficient sedation for only 30 minutes.

Full textAbstract:
There is a lack of an efficient systematic approach to the selection of appropriate construction methods for modern building systems. Identifying key criteria is necessary to help decision-makers in implementing the principles of this process. The present article was conduct for the same purpose. In this article, after reviewing of the literature, we found that construction experts’ opinions did not consider until now. Thus, we considered the opinion of experts in the field of the construction industry (Technical and executive specialists of the Afghanistan’s Ministry of Urban Development and Housing, Technical and executive specialists of the Kabul Municipality and Omran Houlding Group). For identifying key criteria, “64” criteria have been extracted that affect the selection of modern building systems and are classified into “six” economic, qualitative, social, environmental, executive and technical groups. A comprehensive study conducted through the distribution of questionnaires. The collected data were analysed using SPSS statistical software; the main criteria ranked by using “Friedman’s statistical test”. Based on the results of statistical tests, 18 criteria were determined and ranked as fundamental criteria. Therefore, paying attention to these criteria for the selection of appropriate construction methods for modern building systems can help experts in the country of Afghanistan.

Full textAbstract:
The European climate strategy has encouraged the usage of the External Thermal Insulation Composite System (ETICS) to increase the energy efficiency of external building envelopes. This externally and relatively easily applicable façade solution must meet various technical requirements. This paper develops a technical severity evaluation model of on-site construction activities of ETICS to prioritize the risks of the construction process. The model can be used independently by any stakeholder of the construction process. The relevance of the activities is assessed with the Failure Mode Effects Analysis method. The model weights the impact of the essential technical requirements and simulates an integrated weighted technical severity value, which is derived from the analysis of experts’ judgments validated with the non-parametric Friedman’s test. The data collection for probability of occurrence and difficulty of detectability follows the Delphi technique to quantify the opinions of a group. The simulation, conducted on 103 degradation factors, shows that the on-site construction activities of ETICS strongly influence the decrease in the technical resilience of long-term durability, mechanical resistance, and stability, as well as the ability to bypass tensions. The highest risk is detected by the shortcomings in the layers of substrate, reinforcement, adhesive, and additional details.

Purpose: The purpose of this study was to compare the differences between measured (MHRobt) and predicted (MHRpred) maximal heart rate (MHR) in youth athletes. Methods: In total, 30 male soccer players [14.6 (0.6) y] volunteered to participate in this study. MHRobt was determined via maximal-effort graded exercise test. Age-predicted MHR (MHRpred) was calculated for each participant using equations by Fox, Tanaka, Shargal, and Nikolaidis. Mean differences were compared using Friedman’s 2-way analysis of variance and post hoc pairwise comparisons. Agreement between MHRobt and MHRpred values was calculated using the Bland–Altman method. Results: There were no significant differences between MHRobt and MHRpred from the Fox (P = .777) and Nikolaidis (P = .037) equations. The Tanaka and Shargal equations significantly underestimated MHRobt (P < .001). All 4 equations produced 95% limits of agreement of ±15.0 beats per minute around the constant error. Conclusions: The results show that the Fox and Nikolaidis equations produced the smallest mean difference in predicting MHRobt. However, the wide limits of agreement suggests that none of the equations adequately account for individual variability in MHRobt. Practitioners should avoid applying these equations in youth athletes and utilize a lab or field testing protocol to obtain MHR.

Full textAbstract:
Various aspects of protein intake are thought to be crucial for the prevention of sarcopenia in older adults. Information about the day-to-day variation in these aspects is lacking. Our objective was to examine whether daily protein intake, protein distribution across meals, number of meals providing adequate protein, and protein sources vary across the week in healthy community-dwelling older adults. In 140 persons (51% women) that were aged 75–85 years, protein intake was assessed by seven-day food records. On average across the week, protein intake (median [IQR]) was 0.93 [0.79–1.10] g/kg body weight (BW) and the coefficient of variation across the three main meals was 0.50 [0.40–0.61]. The number of meals per day providing ≥0.4 g protein/kg BW was 0.57 [0.43–1.00] and 60.0 [52.4–65.2]% of protein intake was animal-based. According to Friedman’s test, differences throughout the week were observed in women for daily protein intake (p = 0.038; Sunday: 0.99 [0.78–1.31] vs. Tuesday: 0.79 [0.68–1.12] g/kg BW) and number of meals with adequate protein (p = 0.019; ≥1 daily meal: Sunday: 69.4% vs. Tuesday: 41.7%). On Sunday, protein intake was most in agreement with suggestions to prevent sarcopenia. In men, protein intake did not differ throughout the week.

Full textAbstract:
The aim of this paper was to investigate the effects of microwave radiation on the viability of Paenibacillus larvae spores and to study the relationship between the microwave power consumption, the exposure time and the number of spores in the examined suspensions. Sterile distilled water suspensions were made using larval detritus, to contain tens, hundreds and thousands of spores. The suspensions of all the dilutions were gradually exposed to a microwave radiation power of 170, 510 and 850 W. In all the cases, the exposure time was 1, 2, 3, 4, 5, 10, 15, 20, 25 and 30 minutes. After cooling, 0.1 ml of each exposed suspension was inoculated onto three modified MYP (mannitol egg yolk polymyxin) agar plates and incubated aerobically at 37 ± 1 °C for 120 hours. The statistical evaluation of the spore counts decreasing with time was performed with the use of the nonparametric Friedman’s variance test using the Unistat Statistical Package v6.5. The results showed that the rate of devitalisation of the spores is dependent on the microwave oven power consumption, but independent of the number of spores. Using a power consumption of 170, 510 and 850 W, the devitalisation of the spores occurred after 15, 3 and 2 min of exposure, respectively.

Full textAbstract:
The use of cloth face coverings and face masks has become widespread in light of the COVID-19 pandemic. This paper presents a method of using low cost wirelessly connected carbon dioxide (CO2) sensors to measure the effects of properly and improperly worn face masks on the concentration distribution of exhaled breath around the face. Four types of face masks are used in two indoor environment scenarios. CO2 as a proxy for exhaled breath is being measured with the Sensirion SCD30 CO2 sensor, and data are being transferred wirelessly to a base station. The exhaled CO2 is measured in four directions at various distances from the head of the subject, and interpolated to create spatial heat maps of CO2 concentration. Statistical analysis using the Friedman’s analysis of variance (ANOVA) test is carried out to determine the validity of the null hypotheses (i.e., distribution of the CO2 is same) between different experiment conditions. Results suggest CO2 concentrations vary little with the type of mask used; however, improper use of the face mask results in statistically different CO2 spatial distribution of concentration. The use of low cost sensors with a visual interpolation tool could provide an effective method of demonstrating the importance of proper mask wearing to the public.

ABSTRACT: In recent years, several researchers have been studying obesity in national horse breeds; however, no studies demonstrating the dynamic of body and regional fat accumulation (adiposity) Mangalarga Marchador horses subjected to hypercaloric diets have been found. This study aimed to characterize the deposition of body and regional fat in horses with diet-induced weight gain. A total of nine Mangalarga Marchador adult horses with initial body condition score (BCS) of 2.9 ±1/9 (mean ±SD) were subjected to a hypercaloric, grain-rich diet for five months. Body weight and the following morphometric regional adiposity variables were analyzed: BCS, cresty neck scores (CNS), neck circumferences (NC) at 25, 50 and 75% of its length, and accumulation of subcutaneous adipose tissue at the base of the tail using ultrasonography (BTU). These data were collected at baseline and fortnightly after beginning the diet-induced weight gain until the end of the experiment. The effect of time on the variables was verified by analysis of variance (ANOVA) in randomized blocks or the Friedman’s test, and the means were compared by the Tukey’s test (p≤0.05). Exposure to hypercaloric diet promoted a mean weight gain of 27.45% (p<0.001). Significant values were observed for NC at 25 and 75% during the first 45 days of the experiment, and for NC at 50% during the first 30 days. BTU presented significant changes after 60 days, with an increase of 268% compared with the baseline value. These findings demonstrate the weight gain and the dynamic and magnitude of regional adiposity in Mangalarga Marchador horses subjected to hypercaloric diet.
