  • In order to strengthen the reinforced concrete T-beams having insufficient shear strength, several strengthening techniques are available in the literature. In this study, three different strengthening strategies were numerically studied. First one is affixing steel plates to the beam surfaces. Second one includes tightening external steel bars vertically similar to beam stirrups. The last one is simultaneous application of these two strengthening procedures which is particularly proposed in this work. Available experimental test series in the literature were handled in the study. Finite element (FE) models of reinforced concrete beam specimens having sufficient (Beam-1) and low shear capacity (Beam-2) were created within ABAQUS environment. Strengthened beams with different techniques were also modelled to reflect improved shear capacity. FE simulations made it possible to investigate parameters that were not examined during the previous experimental studies. The results of the analyses were then compared and found consistent with the experimentally obtained data. Experimental and FEM analysis results are in agreement between 1% (closest) and 6%. (maximum). Beam-2 was stregthened with 5 new porposed methods. The rate of increase in shear strength varies between 33% and 64%. It was found that, the strengthening techniques were fairly useful in improving the shear capacity of the considered girder. The model with the proposed strengthening alternative has accomplished a higher load carrying capacity, ductility and stiffness than all of the other models.

  • The purpose of this study was to examine the influence of make-up attitude and body-related value on clothing behavior. The subjects were 315 female college students in Gyeongsang provinces. The obtained data were analyzed by reliability analysis, factor analysis, cluster analysis, one-way ANOVA, Duncan's multiple range test, correlation analysis, multiple regression analysis and t-test. The major results of this study were as follows: First, four factors of make-up attitude were identified: pursuit of confidence, sociality, self-satisfaction, and positive image. Second, the subjects were categorized into three different types of groups according to make-up attitude and body-related value, respectively: high involvement type, low involvement type, and middle involvement type. Third, there was significant difference among three groups which were segmented by each make-up attitude and body-related value on clothing behaviors (sexual attractiveness, showing off, body-enhancement). Fourth, a significant positive correlation was found among four factors of make-up attitude and body operatability with clothing behaviors. Fifth, the important variables that affected the clothing behaviors were pursuit of confidence, self-satisfaction, and positive image of make-up attitude. Sixth, body-inclination significantly influenced sexual attractiveness of clothing behavior, whereas body-related value, unlike make-up attitude, only had marginal influence.

  • The purpose of this paper is an analysis of the difference between convergence majors and single majors in the convergence core competency and educational performance. We used survey data for the analysis of the convergence core competencies, the results of the midterm and final exams for the education performance. Analysis targets are 10 students in big data business intelligence at Seokyeong University as convergence majors and 11 students in business administration as single majors. The target course was an analysis of economic data provided in the second semester of 2019. And the lecture contents were analysis of big data using R programming. The survey was conducted on December 5, 2019. The convergence core competences were creative thinking, critical thinking, understanding convergence knowledge, problem solving ability, communication skills, cooperation ability, use of convergence tools, consideration, and responsibility. As results of homogeneity tests, we found that there was no significant difference in all competencies, but there were very significant differences in the educational performance evaluated by the midterm and final exams. Therefore we can see willingness to convergence of single majors was no different from that of convergence majors, but had not led to practice. It is desirable to activate and support convergence courses.

  • This study examines underwear purchase behaviors and the attitude of male consumers based on the degree of interest in appearance. Data research was conducted on 296 males in their 20s and 30s located in Seoul & Gyeonggi province. The SPSS 17.0 software program was used to conduct data analyses such as descriptive statistics, frequency analysis, factor analysis, cluster analysis, t-test, and $\chi^2$-test. The results of this study are as follows: The degree of interest in appearance was identified with four factors; outfit management, confidence of figure, interest in clothing, weight control, and disinterest in appearance. Customers were segmented into two subdivisions: high and low interest in appearance. The factors derived from the factor analysis of underwear purchase motive included aesthetic, impulsiveness, and practicality. The purchase behavior of the group with high interest in appearance was highly motivated by aesthetics and impulsiveness. The factors derived from the factor analysis of underwear attitude included fashionability, comfortableness, and quality. Customers were segmented into the following three subdivisions: pursuit of comfortableness, pursuit of diversity, and normal. The type of high interest in appearance regarded fashionability and quality highly. Finally, the degree of interest in appearance showed significant relevance in purchase motive and underwear attitude for underwear.

  • Objectives: Diet and incidence of chronic diseases are highly related. This study examined the characteristics of dietary safety awareness and competency for chronic disease prevention among adults. Methods: Data were collected from 247 adults in Daegu and Gyeongbuk areas using a self-administered questionnaire in May and June of 2018. Data were analyzed by frequency analysis, χ2-test, factor analysis, reliability analysis, t-test, one-way analysis of variances, and correlation. Results: The results of the factor analysis indicate that dietary safety awareness of health management was classified into chronic disease anxiety and obsession. Awareness of dietary safety management was sub-grouped into difficulty in acquiring knowledge, lack of awareness of over and malnutrition, food safety anxiety, importance of weight management, education requirement for cancer prevention, and knowledge. Dietary safety behavior composed of a balanced diet, unhealthy diet, and health-functional pursuit. Dietary safety management competency was comprised of health management, food management, and cooking. The competency scores of dietary safety management factors were significantly different according to sex, age, and education level (P < 0.05). Balanced diet factor was significantly correlated with knowledge, health-functional pursuit, health management, food management, and cooking capacity factors (P < 0.01). Conclusions: Active education for dietary safety management competency according to age, gender, and education level should provide dietary safety education to reduce anxiety and obsession regarding chronic diseases and sustainable health management.
