Pilot Selection

In 1992, Park and Lee published a paper in Human Factors on the use of a computerized battery to select pilots for the Korean Air Force. In the present article we describe problems associated with the selection, implementation, and administration of the tasks constituting the computerized battery in Park and Lee. Problems associated with the data analysis are also discussed and focus on factor interpretation and nonindependent statistical tests. We offer some general guidelines for developing computerized pilot selection batteries and data analysis.

The purpose of this study was to determine the factors that affect directly and indirectly such as promotion, convenience, and security on the decision to purchase online cinema tickets with the TIX ID application through consumer buying interest. The data collection technique uses a questionnaire that is distributed online via the google application form. Data analysis methods include validity, reliability, classical assumptions, and SEM tests. The number of samples in this study were 200 respondents who had met the minimum requirements for using SEM (structural equation models). Data processing using SPSS and AMOS. The results showed that promotion and convenience factors had a significant effect on purchase intention, while security did not have a significant effect on purchase intention. The results of statistical tests show that there is no influence of the promotion, convenience, and security variables on purchasing decisions. Furthermore, the results show that promotion and convenience factors indirectly influence purchasing decisions through purchase intention.

This symposium will review the technical findings of an Air Force-contractor study that comprehensively examined the needs of human factors engineering in the research, development, test-and-evaluation and operations process for Air Force systems. A nine-month team effort concluded in September 1979 constituted one of the most intensive and extensive inquiries into the human factors field that has been undertaken.

Peste Des Petits Ruminants

Objective. Estimate the prevalence and spatial modeling of PPR in the small ruminant population of Chaharmahal and Bakhtiari, Iran, during 2009–2014. Materials and methods. Data were collected from veterinary organization and Offices in Chaharmahal and Bakhtiari province and data analysis was carried out using and IBM SPSS version 22 and Office 2010. For spatial modeling geographic information system (QGIS and PCI-Geomatic) was used. Results. This study showed that the overall prevalence of PPR during the years 2009 to 2014 was 1.37%. Koohrang, Ardal, Lordegan, Ben, Borougen, Shahrekord, Farsan and Kiar cities had the highest prevalence of PPR, respectively. The highest PPR infection rate was observed in the March and goat more affected rather than other ruminants. Conclusions. Our findings provide evidence of a rather common prevalence of PPR and its spatial distribution in Chaharmahal and Bakhtiari province. Using statistical tests for data analysis of PPR and its spatial modeling researchers can predict the incidence of disease in the future and could select appropriate measures of disease control.

The present research aim was to assess how occlusal contacts change along the initial 6 months of orthodontic treatment with fixed appliance and clear aligners. A sample with 40 patients was divided into 2 groups: Clear Aligners (CA) and Fixed Appliance (FA). In order to register occlusal contacts, patients were posit and instructed about how bite in habitual maximum intercuspidation. Registrations were perfomed monthly along 6 starting treatment months and noted in an occlusogram. A parametric test was applied to evaluate data since it presented a normal distribution according to Shapiro-Wilk test. For inter- and intergroup data analysis the Anova test was performed with a 5% significance level. Statistical tests were executed on Jamovi software (Jamovi Stats, Version1.2, Sydeney, Australia). There was a reduction in the amount of occlusal contacts for indivduals from both groups, CA and FA. Such reduction was more significative in the 3 starting months for FA group and between 3rd and 4th months for CA group. Therefore, the sort orthodontic appliance had no significant influence over occlusal contacts.

Probability And Statistics

Mathematics is the language of quantitative science, and probability and statistics are the extension of classical logic to real world data analysis and experimental design. The basics of mathematical functions and probability theory are summarized here, providing the tools for statistical modeling and assessment of experimental results. There is a focus on the Bayesian approach to such problems (ie, Bayesian data analysis); therefore, the basic laws of probability are stated, along with several standard probability distributions (eg, binomial, Poisson, Gaussian). A number of standard classical tests (eg, p values, the t-test) are also defined and, to the degree possible, linked to the underlying principles of probability theory. This review contains 5 figures, 1 table, and 15 references. Keywords: Bayesian data analysis, mathematical models, power analysis, probability, p values, statistical tests, statistics, survey design
