Due to the recent aircraft accidents both in Ethiopian airline and Malaysian airline, almost all the media are focusing the importance of the airline safety. Especially, media's eyes and ears are interested in the reasons why Malaysia airline's missing presumed as by either terrorist attack or pilot's mistake. Safety Behaviors of pilot are viewed as the most important human factor issues among researchers. This is because, if it were the case of a commercial airline, pilot's safety behavior would be directly related to the lives of couple of hundreds passengers. This paper considers the antecedents of this safety behaviors as pilot's leadership, pilot's leadership and self-efficacy. This paper has tried to find out which human factors of a pilot would have significant impact on their safety behaviors. According to the empirical research result from SEM (Structural Equation Model), it was found out both the leadership and self-efficacy of a pilot had direct impact on their safety behaviors through safety motivation. Thus it could be concluded that flight crew must follow the instruction of a pilot who had the authority of the flight operation. The managerial implication are discussed in the conclusion part of this paper. As an implication, this paper concluded that it would be necessary to do further research on pilot's leadership and self-efficacy.

The purpose of this study was to make a comparative analysis of dietary habits, snacks, eating out and fast-food intake between students with a relatively early sexual maturity and others with a relatively late sexual maturity in a bid to grasp the impact of dietary behaviors on sexual maturity. The subjects in this study were 565 boys and girls who resided in Seoul and Gyeonggi province. They included fifth- and sixth-grade school children and seventh-grade middle school students. To classify the selected students according to the level of sexual maturity, the students of the same month age were divided into two groups in consideration of the stage of their sexual maturity and that of the other age groups. The early mature group was significantly taller and weighed more than the late mature group irrespective of gender. According to Tanner stages, the boys of the early mature group reached a 3.03 stage of sexual maturity when the sexual organs were taken into account, and those of the late mature group reached a 1.50 stage of sexual maturity. The girls of the early mature group reached a 3.43 stage of sexual maturity on the basis of breast, and those of the late mature group reached a 2.73 stage of sexual maturity. Concerning eating out, the early mature group ate out more frequently than the late mature group. In regard to snacks, the early mature group had a snack more often. The findings of the study indicated that there were differences in physical development and some dietary behaviors according to sexual maturity. The early mature group had a snack and ate out relatively more often than the late mature group, which showed that some dietary behaviors had an impact on the sexual maturity of the teens who arrived at the age of puberty.

This study aims to investigate the factors on help-seeking behaviors among the disabled experiencing lifelong domestic violence and suggest practical plans to address the problems. According to an analysis of the data of the "2010 Domestic Violence Survey of South Korea", the occurrence rate of lifelong physical violence is 12.1% and that of severe physical violence is 6.2% among 273 adults with disabilities. The rate of help-seeking among the disabled experiencing lifelong domestic violence is 26.3%, which means two-thirds of the disabled experiencing domestic violence do so for a long time. The results of the study show that the experience of severe physical violence(p<.05), attitudes toward violence(p<.05), and awareness of domestic violence and related laws(p<.05) were found to have an impact on help-seeking behaviors among adults with disabilities experiencing domestic violence. However, an accepting attitude of disability and social connections of disabled were not found to have an impact on help-seeking behaviors. Based on these results, this study suggested raising awareness about domestic violence among the disabled, educating people with disabilities not to tolerate violence and informing them about the domestic violence-related legal system, and training service professionals (social workers, health professionals etc.) to screen the disabled for domestic violence and prevent them from becoming domestic violence victims.

Purpose : This study aimed to investigate the leisure satisfaction of participants in the Geod-Jyu walking program and to examine the relationship between health promotion behaviors and quality of life. In addition, we investigated the impact of leisure satisfaction with walking among program participants on health promotion behaviors and quality of life. By clarifying these relationships, we aimed to identify factors of leisure satisfaction with walking that could enhance participants' health promotion behaviors and quality of life. Methods : A survey was conducted among 301 participants enrolled in the Geod-Jyu walking program in Chungcheongnam-do, with 288 responses analyzed. Data analysis included Pearson's correlation, confirmatory factor analysis, and multiple regression analysis using SPSS 27.0. Result : Leisure satisfaction exhibited a positive correlation with health promotion behavior (r=.544, p<.01) and quality of life (r=.478, p<.01). Furthermore, health promotion behavior showed a positive correlation with quality of life (r=.636, p<.01). Leisure satisfaction positively influenced quality of life, with physiological satisfaction (β=.16, t=2.32) and relaxation satisfaction (β=.15, t=2.04) emerging as notable contributors. In addition, leisure satisfaction had a significant positive impact on health promotion behaviors, with psychological satisfaction (β=.24, t=3.09) and educational satisfaction (β=.20, t=3.09) playing key roles. Health promotion behavior had a positive impact on quality of life, with all sub variables exhibiting significant positive effects in the following order: self-actualization (β=.24, t=4.16), stress management (β=.22, t=3.97), exercise (β=.22, t=4.05), and health responsibility (β=.12, t=2.14). Conclusion : The findings indicate that factors related to physical and rest satisfaction, as well as health-promoting behaviors facilitated by walking, significantly affected the quality of life among Geod-Jyu participants. Thus, promoting leisure satisfaction and engaging in health-promoting activities through walking can enhance overall well-being. Encouraging participation in the Geod-Jyu walking program is critical for physical and psychological benefits, and for promoting healthier behaviors. Further development of Geod-Jyu is expected to enhance walking satisfaction, promote self-care skills for health management, and positively influence quality of life.

충격 하중 재하 실험의 경우 빠른 하중 재하 속도로 인해 실험 데이터를 측정하는 방법에 있어 많은 어려움이 있다. 또한 부재의 국부적 손상을 측정하지 못함으로써 부재의 동적 거동을 왜곡하는 문제점이 존재한다. 따라서, 본 연구에서는 충격 실험에서의 한계를 극복하기 위하여 명시적(explicit) 유한요소 해석 프로그램인 LS-DYNA를 이용하여 FRP Sheet 및 강섬유로 보강된 콘크리트의 저속 충격 하중 하에서의 동적 거동을 분석하였다. 해석 모델은 1방향 및 2방향 부재이며 충격 하중 재하 시부재의 국부적 파괴를 고려하고 있다. 해석결과 강섬유에 의해 보강된 SFRC와 UHPC 부재의 경우 충격 저항성능이 크게 향상되었다. FRP Sheet로 보강한 경우 GFRP가 CFRP보다 우수한 충격 저항 성능을 보였으며 FRP Sheet의 방향성에 의한 영향은 크게 나타나지 않았다. 본 연구에서 수행된 해석은 충격 실험 결과와의 비교를 통해 그 신뢰성이 검증되었다.

This research is to analyze the wave propagation characteristics of anisotropic materials subjected to the low-velocity impact. For this purpose, a higher-order finite element program is used to simulate the dynamic behaviors according to the changes of material property, stacking sequence and dimension etc.. Materials for simulation are composed of $[0^{\circ}]_{10s}$, $[45^{\circ}/-45^{\circ}]_{5s}$ and $[90^{\circ}]_{10s}$ stacking sequences. Finally, the results of this simulation are compared with those of wave propagation theory and then the impact responses and wave propagation phenomena are investigated.
