Abstract Purpose Stereopsis is a fundamental skill in human vision and visual actions. There are many ways to test and quantify stereoacuity: traditional paper and new digital applications are both valid ways to test the stereoacuity. The aim of this study is to compare the results obtained using standard tests and the new Stereoacuity Test App developed by the University of Bergamo. Methods A group of 497 children (272 males), aged between 6 and 11 years old, were tested using different tests for the quantification of stereopsis at near. These tests were TNO, Weiss EKW, and the new developed Stereoacuity Test App. Results A one-way repeated measure ANOVA showed that the three tests give different thresholds of stereoacuity (p < 0.0001). Post hoc analyses with Bonferroni correction showed that all tests showed different thresholds (p < 0.0001). The lower threshold was obtained by Titmus Stereo Test followed by Stereoacuity App, Weiss MKW, and TNO. Conclusion The stereoacuity based on global stereopsis showed that the better values were obtained in order by Stereoacuity Test App, TNO, and Weiss EKW. However, the clinical significance of their values is similar. The new digital test showed a greater compliance by the child, showing itself in tune with the digital characteristics of today’s children.

Governments the world over are increasingly challenging universities to produce human resources with the right skills sets and knowledge required to drive their economies in this twenty-first century. It therefore becomes important for universities to produce graduates that bring tangible and meaningful contributions to the economies. Graduate tracer studies are hailed to be one of the ways in which universities can respond and reposition themselves to the actual needs of the industry. It is against this background that this study was conducted to establish the relevance of the Department of Information and Communication Technology at Mzuzu University to the Malawian economy by systematically investigating occupations of its former students after graduating from the University. The study adopted a quantitative design by distributing an online-based questionnaire with predominantly closed-ended questions. The study focused on three key objectives: to identify key employing sectors of ICT graduates, to gauge the relevance of the ICT programme to its former students’ jobs and businesses, and to establish the level of satisfaction of the ICT curriculum from the perspectives of former ICT graduates. The key findings from the study are that the ICT programme is relevant to the industry. However, some respondents were of the view that the curriculum should be strengthened by revising it through an addition of courses such as Mobile Application Development, Machine Learning, Natural Language Processing, Data Mining, and LINUX Administration to keep abreast with the ever-changing ICT trends and job requirements. The study strongly recommends the need for regular reviews of the curriculum so that it is continually responding to and matches the needs of the industry.

AbstractRegenerative endodontic procedures have gained momentum as a treatment modality of young immature permanent teeth. Literature reports reveal that platelet-rich fibrin (PRF) stimulates growth factors and induces regeneration. This study was undertaken to assess the regenerative potential of non-vital immature permanent maxillary central incisors using PRF with a follow-up for 2 yrs. 19 patients in the age group of 9–25 yrs with immature, non-vital permanent maxillary central incisors (n = 23) with/without signs and/or symptoms of periapical pathosis and open apex were included in this study. In the first appointment, access opening, canal disinfection and triple antibiotic paste placement were done. In the subsequent visit, PRF was prepared and placed inside the canal. Access was sealed with Mineral trioxide aggregate plug and composite. The patient was reviewed up to 24 mths. The mean difference was statistically analyzed using Friedman test followed by Dunn post hoc test and adjusted by Bonferroni correction (p < 0.05). As per AAE guidelines, the primary and secondary goals were achieved. A significant (p < 0.001) gradual increase in the root length, thickness of dentinal walls and decrease in apical diameter were observed. Within the limitations of this study, PRF placement was clinically and radiographically effective in inducing regeneration of non-vital immature permanent teeth.

Comparative Analysis of Barefoot and Shod Running This study investigated the biomechanical difference between running barefoot and shod before and after a barefoot training program (BTP). Foot angles at contact (FA), contact time (CT), stride length (SL), initial contact force (ICF), and total peak force (TPF) in shod and unshod runners was analyzed. Fourteen collegiate runners attended 12 total sessions over a two week period. Subjects performed a baseline trial, running eight (10-20 meter) repetitions, four barefoot and four shod, at three different stations; running over a force plate, running in front of a SONY DCR-HC52 video camera (30fps) and running in front of a Casio Exilim Pro EX-F1 camera (300fps). A Post-Test (PT) was conducted at the end of the BTP. A repeated measure ANOVA showed significance (p<.05) in the Test factor, BTP; lowering participants FA mean from 18.8deg+/-.9deg to 5.6deg+/-15.1deg, CT mean from .221m+/-.02m to .2m+/-.03m, and TPF mean from 1427.4N+/-312.9N to 1348.2N+/-269.4N. A repeated measure ANOVA showed significance (p<.05) in the Condition factor (shod vs. unshod); lowering participants FA mean from 23.1deg+/-12.6deg to 1.3deg+/-14.4deg, SL mean from .9m+/-.1m to .8m+/-.1m, and ICF mean from 1465.3N+/- 369.6N to 1324.7N+/-379.4N. Running barefoot and following a BTP alters running biomechanics in ways that may decrease running related injuries.

Objectives The aim of the study was to evaluate the appetite-stimulating effect of gabapentin by comparing it with mirtazapine in healthy cats in the first 8 h after ovariectomy surgery. Methods This double-masked, placebo-controlled, prospective clinical trial included 60 healthy cats presented to the hospital for ovariectomy: 20 received gabapentin, 21 received mirtazapine and 19 received a placebo immediately before and 6 h after surgery. Food was offered at 2, 4, 6 and 8 h post-ovariectomy. After each meal, food intake was measured. Data were analysed using repeated-measure ANOVA and a linear mixed-model analysis. Post-hoc Tukey’s honest significant difference test was performed for multiple comparisons. Results Food intake increased in both treatment groups vs placebo. No statistically significant difference was found between cats treated with gabapentin or mirtazapine. Conclusions and relevance Cats receiving gabapentin ate more than cats in the placebo group. Thirty percent of cats in the gabapentin group covered their resting energy requirements, while none of the cats in the placebo group did. Gabapentin and mirtazapine produced similar effects on food intake.

This study, considering the sample of a university located in central Anatolia region, Turkey, aims to identify culture types that the academicians perceive in relevant with their institutions according to the 4 types of cultures (Clan, Adhocracy, Hierarchy, and Market) given in the Competing Values Framework by Cameron and Quinn. The study includes 205 academicians from different faculties and vocational schools as participants. The data was obtained from the Organizational Culture Assessment Instrument (OCAI) that has been prepared particularly for the research group. Analyzes of the data obtained in the study were carried out with statistical package programs as IBM SPSS Statistics 23 and Interactive Lisrel SSI 8.72. The demographic features of the academicians were determined with percentage and frequency analyzes and the mean and standard deviation statistics were used in determining the perception levels of organizational culture types which academicians associate with their universities. For the analysis of the differentiation of culture-type perception levels according to the demographic characteristics of the academicians, t-test, one-way ANOVA test, and post-hoc tests were performed. According to the findings obtained in the research, the most common type of organizational culture that academicians associate with their institution is the hierarchy culture that is presented in Competing Values Framework Model. There is no significant difference between participants' demographic features and their culture perceptions. According to the result of the research, rules, stability, predictability, and sustainable politics are at the forefront of the university. Employees are supervised by managers who tend to be good coordinators.

Conducted in English-as-a-foreign-language (EFL) classrooms at the university level in China, this quasi-experimental study compared the effects of three different corrective feedback treatments on 72 Chinese learners’ use of regular and irregular English past tense. Three classes were randomly assigned to a prompt group, a recast group, or a control group and then participated in form-focused production activities that elicited the target forms. In the two feedback groups, teachers consistently provided one type of feedback (i.e., either recasts or prompts) in response to learners’ errors during the activities, whereas in the control group, the teacher provided feedback only on content. Pretests, immediate posttests, and delayed posttests administered 2 weeks after the treatment assessed participants’ acquisition of regular and irregular past tense forms in both oral and written production. Comparisons of group means across testing sessions using a repeated-measures ANOVA consistently revealed large effects for time. Post hoc within-group analyses of the eight immediate- and delayed-posttest measures revealed significant gains by the prompt group on all eight measures, the recast group on four, and the control group on three. The effects of prompts were larger than those of recasts for increasing accuracy in the use of regular past tense forms, whereas prompts and recasts had similar effects on improving accuracy in the use of irregular past tense forms.

Tablet based application (TBA) has been shown to be useful in evaluating soccer players’ performance. However, a study investigating the ability of the application as a medium for feedback is desirable. This study aims to examine the effectiveness of TBA as a medium for feedback in real time at half-time interim of a competitive match in improving the performance of soccer players. StatWatch application was installed on a tablet phone and used as a device for data collection. Eleven performance analysts were recruited to assist in the data collection such that each performance analysts covered a particular player during the game. Players Performances were assessed based on performance parameters relevant to the demand of the game. Data were collected as the game progressed, and information was transmitted to the controller of the analysis before being relayed to the chief coach at the half time interval of the match. Matches of the club for eight weeks were analysed. One-way repeated measure ANOVA was used to assess the progress of the team in between the first and second halves of the matches played. The result shows improvement on the performances of the club at the second halves of the eight matches played (F (1, 14.10) = 8.94, p < .05). A follow-up test demonstrates a significant progress on the overall team performance from week1 to week 8, p > 0.001. TBA appeared to be a useful medium for providing feedback at a first half interval of a competitive match for improving the performance of soccer players during the subsequent.

Overweight Or Obesity

Obesity, as the most common metabolic disorder in the world, is characterized by excess body fat. This study is aimed at determining the effects of melatonin supplementation on body weight, nody mass index (BMI), waist circumference (WC), and body fat mass percentage (BFMP) in people with overweight or obesity. Thirty eight overweight or class-I obese adult individuals were recruited in the study (8 men and 30 women). Participants prescribed a weight-loss diet and then randomly were allocated to melatonin or placebo groups. Participants received either a 3-milligram melatonin or placebo tablet per day for 12 weeks. In order to assess differences at the significance level of 0.05, repeated measure ANOVA and paired t -test were used. According to the results, a significant reduction was found in participants’ body weight, WC, and BMI in both groups ( p = 0.001 ). However, for the last six weeks, significant reductions of these parameters were observed only in the melatonin group ( p = 0.01 ). The BFMP of participants in the melatonin group showed a significant reduction at the end of the study compared to the initial measurements ( p = 0.008 ). Nevertheless, the results of the present study alone are not sufficient to conclude on the effects of melatonin consumption on anthropometric indices, and it seems that further studies are required in this regard.
