This study was conducted to testing the criterion - related validity of a mental health assessment tool which developed based on a korean culture. Criteria scale for this tool were MMPI and CMI(M - R). The study subject were 100 male and female aged 20 or more with quota sampling. The data was collected from August 16. to August 26. 1989. The data obtained from 85 subjects were analysed using S.P.S.S.(Stastistical Package for the Social Science). As a result, there are no significant correlation between Mental Health Assessment Tool and MMPI and CMI except Mf(Masculinity-Feminity) Subscale of MMPI. This result means the MMPI and CMI was not related to tool which developed based on medical model from etic perspectives, although the tool which had been developed in America Modified to Korean situation. So I dare to say that only the absence of mental illness does not means mental health and the diagnosis of mental illness is not the only criteria of a mental health.

본 연구의 목적은 학생 (인구)수를 예측하기 위한 방법을 제시하는데 있다. 일반화된 가중비례모형들을 제시하고, 제시된 모형들을 이용하여 2029년까지의 학생 (인구)수를 추계하였다. 몬테칼로 모의실험의 결과 제시된 가중비례추정모형은 인구예측에 있어서 상당한 신뢰성과 예측력을 보인다. 결론적으로 추정된 고등학교 3학년 학생수는 대학들의 입학정원 수와 비교하면, 2019년부터 고3 학생수가 적게 나타나지만, 현재 대학들의 실제 입학자 수와 비교하면 2014년부터 입학생 수가 부족한 현상이 나타난다. 그러므로 입학정원과 입학정원 외의 신입생 수를 줄이지 않는 경우에는 2015년부터 입학생을 채우지 못하는 학교들이 생겨나게 될 것이다.

This research tested the path model which examined the direct and indirect effects of family violence experience on perpetration of dating violence among college students. Two family violence variables such as witnessing parents' marital violence and being abused by parent were the exogeneous variables in the path model, while the mediated variables were consisted of (1) the social-learning-theory-derived variables such as acceptance of violence, positive outcome expectations of using violence, and aggressive conflict-coping behavior, and (2) control-theory-derived variables such as attachment, belief, and commitment. Data were from self-administered questionnaires completed by 332 male and 469 female students selected by stratified quota sampling method. The path analysis was done for males and females separately, since females reported significantly higher degree of dating violence than males. Results of the path analysis showed that first, for both males and females, being abused by parents directly and indirectly influenced dating violence, while witnessing parents' marital violence did not have effect on dating violence either directly or indirectly. Second, for male students, acceptance of violence and conflict coping behavior found to be the mediated variables in the effect of being abused by parents on dating violence. Third, for females, a control-theory-derived variable of belief as well as all three social learning theory-derived variables mediated the influence of being abused by parents on dating violence.

Purpose: Due to the rapid growth of e-commerce in Thailand, the operational excellence of distribution service providers has been elevated. Thus, this research investigated the key drivers of operational performance of e-commerce distributors in Thailand. The research contains key variables: the analytics capabilities of an organization, supply chain disruption orientation, innovation capability, and operational performance. Research design, data, and methodology: An online survey is administered to top managers and key personnel (N=425) employed for at least one year in Thailand's top five e-commerce distributors. The sampling methods were conducted using purposive sampling, quota sampling, and convenience sampling. Confirmatory Factor Analysis and Structural Equation Model were applied to analyze and confirm the model's goodness-of-fit and hypothesis testing. Results: The findings reveal that an organization's analytics capabilities significantly affect supply chain disruption orientation and supply chain resilience. Furthermore, operational performance is affected by supply chain disruption, supplier quality management, and innovation capability. Nevertheless, supply chain resilience and digital supply chain have no significant effect on operational performance. Conclusions: The results imply that supply chain digitalization could drive higher operational performance. Distribution businesses are encountering transformation and disruption, which should address the high level of a digital supply chain, innovation, and quality management to maximize their profit margin and delivery service quality.

Purpose: Virtual reality is a unique technology to distribute data and demonstrates user's understanding towards complex products. The objective of this research is to investigate the impact of virtual reality on real world purchase intention of automotive cutting tools in Thailand's exhibitions. Hence, the research framework was constructed by telepresence, perception narrative, authenticity, trustworthiness, functional value, aesthetics, and purchase intention. Research design, data and methodology: Samples were collected from 500 visitors who participated in the selected top two metalworking exhibitions. Mix sampling approach is applied by using non-probability sampling methods of purposive or judgmental sampling, quota sampling, and convenience sampling method, respectively to reach target samples. Confirmatory Factor Analysis (CFA) and Structural Equation Model (SEM) were used to analyze and confirm goodness-of-fit of the model and hypothesis testing. Results: The results indicate that authenticity, functional value, and trustworthiness induced higher experiential value towards purchase intention. Those variables are stimulated by telepresence and perception narrative towards VR experience. Conclusions: Consumer's purchase intention towards VR experience on engineering cutting tools rely on consumer's sense of authenticity, trustworthiness, and functional value. Hence, marketing practitioners in automotive companies are encouraged to develop VR which focusing on significant factors to enhance consumers purchase intention.

본 연구는 미국 멕시코만의 Yellowedge Grouper 어업을 사례로 생물경제학 모델을 이용하여 자원회복계획 하의 총 허용어획량(TAC) 어업관리정책 효과를 분석하였다. 생물학적 자원평가모델인 잉여생산량 모델의 추정 결과 자원이 남획상태인 것으로 나타났고, 그 결과 10년 기간 동안 TAC제도를 이용하여 목표 자원량 달성을 위한 자원회복계획이 수립되어졌다. 모델 분석 결과, 통제관리가 잘 이루어진다면 자원회복기간 이후에 목표 자원량 수준이 달성되는 것으로 분석되었다. 하지만, 목표 자원량 달성을 위해서는 자원회복기간 동안의 어획량이 크게 감소되어야 하는 것으로 나타났는데, 특히 NMFS가 권고한 연간 342톤 어획량보다 더 크게 어획량이 감소해야 하는 것으로 분석되었다. 향후 25년 동안 발생할 어업 이익은 자원회복기간 동안의 어획량 감소로 인하여 현 상태유지 하에서보다 적은 것으로 나타났다. 그리고 사회적 할인율이 낮을 때는 변동어획량 TAC제도 하에서 고정어획량 TAC재도 하에서보다 큰 어업이익이 발생하였지만, 할인율이 높아질수록 고정어획량 TAC제도 하에서 변동어획량 TAC제도 하에서보다 큰 어업이익이 발생하였다.

다기능 레이다는 자원관리를 통해 표적을 탐색함과 동시에 추적한다. 한정된 자원에서 표적이 많을수록, 추적 갱신률이 빠를수록 추적에 할당되는 자원이 증가하여 탐색 자원 할당량이 감소하게 된다. 탐색 자원이 감소하면 표적의 탐지 재방문 시간, 포착 기회 수, 추적 등의 여러 레이다 탐색 성능이 저하된다. 자함 방어와 같은 복합전술 상황에서 탐지성능 저하는 유도탄의 방어 확률을 감소시킨다. 본 논문에서는 이러한 복합적인 전술상황에서의 자함 방어 분석을 위해 다기능 레이다를 탑재한 자함 모델, 레이다 모델, 표적 모델, 방어 모델 등을 구성하여 M&S도구를 개발하였다. 이를 통해 다양한 표적 환경 및 추적 성능에 따른 자함 방어의 영향성을 복합적으로 분석하였다.

Since 2012, despite the fact that tariff rate quotas (TRQ) in the form of dried peppers has not been imported, the imports of pepper-related items such as low- tariff frozen peppers (27%) and other sauces (45%) have increased, there has been a problem in the domestic pepper industry, in which the domestic self-sufficiency rate has declined. The purpose of this study was to find out whether the operation of chili pepper TRQ has the effect of suppressing the imports of pepper-related items from China. We analyzed the import substitution effect (import suppression effect) through causal analysis of the imports of red pepper TRQ, frozen peppers, and other sauces using the structural equation model analysis method. As a result of the hypothetical scenario analysis, when the government imports and releases 7,185 tons of pepper TRQ in 2019/20 (scenario), private imports were estimated to decrease by only 3,060 tons. In other words, the import substitution effect between imported items was estimated to decrease about 2,079 tons of private dried peppers, and about 981 tons of imported pepper-related items. There was an effect of suppressing the imports of pepper-related items such as frozen peppers, but it was analyzed to be insignificant. That reason was that the replacement substitution elasticity of the pepper-related items for TRQ import was less than 1 (inelastic). Therefore, it is judged that the government's operation of the pepper TRQ is preferably focused on stabilizing domestic prices rather than focusing on import control of pepper-related items.
