The purpose of this study is to examine the effect of private tutor's job stress on the organizational commitment and turn-over intention and to verify the mediating effect of the organizational commitment. The questionnaire survey was peformed for 332 private tutors in special education region in Seoul. The collected data were used as a model of path coefficients obtained through analysis of structure equation model(SEM) and hypothesis verification. The result of the verification is as follows. First, both stress by student and stress by administrative support showed statistically significant negative effects on the organizational commitment. Second, the private tutor's organizational commitment showed a statistically significant negative effects on the turn-over intention. Third, both stress by task and stress by conflict in organization showed statistically significant positive effects on the turn-over intention. Fourth, even if both stress by student and stress by administrative support showed statistically no significant effects on the turn-over intention, they showed statistically significant effects on the turn-over intention with the mediating effect of the organizational commitment. It was confirmed that the turn-over intention can be decreased by relief of the private tutor's job stress and enhancement of the organizational commitment. In this process, it is meaningful to verify the role and function of the private tutor's organizational commitment.

The purpose of this study was to examine the validity and reliability of the Playfulness Scale for Adults. The Korean version of the Playfulness Scale for adults was developed by Proyer, R.T (2017) to measure the playfulness of adults. To validate the OLIW in Korean, item translation, back-translation, item analysis, and exploratory factor analysis (EFA) were conducted with 406 adults in study 1. Of the results obtained from study1, three items and one factor (7 items) were discarded because they turned out to be improper. In addition, 4 factors that were not the same as the original scale were extracted. This was checked by conducting confirmatory factor analysis (CFA) with 336 adults in study 2. CFA supported the 4 factors structure and all 4 factors showed adequate internal consistency. To check the concurrent validity of the Korean adults playfulness scale, correlation analysis with the APS, SMAP, PSYA, and NEO Personality Assessment was conducted. It showed significant positive correlation to APS, SMAP, PSYA, and showed the similar patterns of correlation with the sub factors of NEO Personality Assessment. Adult playfulness is related to the participation frequency of leisure. In conclusion, the Korean version of the playfulness scale for adults is a valid measure of playfulness for adults in Korea. The implications, practical use and suggestions for future study were discussed.

연구배경: 데이트 폭력은 청소년을 포함한 젊은 인구집단의 신체적, 정신적 건강을 위협하는 중요한 공중보건 문제이다. 친밀한 남녀관계에서 시작되는 데이트 폭력의 위협에 노출되는 시기가 바로 청소년들이 생애주기 상 가장 급격히 발달하면서 많은 변화를 겪는 시기라는 것이 더 민감한 관심을 끈다. 그러나 이 문제 또는 이 문제를 해결하기 위한 노력들의 정도와 심각성을 이해하기 위한 구조적인 노력은 그다지 많이 이루어지지 않았다. 연구목적: 본 연구의 목적은 미국 청소년과 성인 초기 연령집단의 데이트 폭력 예방, 측정 도구, 위험 요인, 이환정도에 대해 지금까지의 관련 연구자료 고찰하여 일반적인 경향을 소개하는데 있다. 연구방법: 1990년부터 2007년까지 발표된 청소년과 성인 초기 인구의 데이트 폭력에 관한 60개의 논문을 검색하여 고찰하였다. 사회과학과 보건과학 관련 연구논문의 검색모듈을 활용하였는데 PsycInfo, Pubmed, 그리고 CINAHL였다. 연구결과: 데이트 폭력의 위험요인은 크게 개인적 요인, 심인적 요인, 가족 요인, 학교 및 친구 집단 요인으로 나뉘어진다. 개인적 요인으로는 자아존중감, 성, 인종, 약물사용, 성상대자 수, 과거 폭력경험이 유의미한 것으로 나타났다. 이 밖의 다른 개인적 요인, 즉 심인적 요인으로는 자기효능감, 식습관, 반사회적 행동 등이 있었다. 가족 요인으로는 가족 구조, 부모 성향이 유의미한 특성들이었으며 이 밖에 학교, 친구, 지역사회의 환경적 요인이 관련 있는 것으로 보고되었다.

This article is to examine the influence of occupational stress, socio-psychological factors and quality of sleep on fatigue symptoms from firefighters in fire service. The correlation coefficients were obtained by a tool of Pearson analysis, and covariance structure analysis was performed on the factors affecting the level of fatigue symptoms. This result suggests that the level of firefighters' fatigue symptoms in fire service. has a causal effect with occupational stress, socio-psychological factors and quality of sleep. Therefore, it is necessary to improve the work environment and to increase organizational support to deal with firefighters' fatigue in fire service.

This paper presents an application of adaptive algorithms for yaw moment distribution with electronic stability control (ESC) and active rear steering (ARS) in integrated chassis control (ICC). Integrated chassis control consists of upper- and lower-level controllers. In the upper-level controller, the control yaw moment is computed with sliding mode control required to stabilize a vehicle. In the lower-level controller, adaptive algorithms are applied to determine the required brake pressure of ESC and the necessary steering angle of ARS, in order to generate the control yaw moment. Simulation is performed using the vehicle simulation package CarSim to validate the proposed method.

As human factors are the most important cause of construction accidents, it is important to reduce human error in construction work to reduce accidents. However, the error forcing context in organizational situations acts as a factor behind human error. Therefore, fatal construction accidents were analyzed using the m-SHEL model, which can identify the factors behind human errors. Through such analysis, it was found that there are differences in the detailed factors behind human errors according to the type of fatal accidents in construction, This study is meaningful in that it confirmed through accident cases that it is important to understand and respond to organizational situations in order to reduce human error in construction work.
