Impulse buying has been considered a pervasive and distinctive phenomenon in the modern lifestyle and has been receiving increasing attention from consumer researchers and theorists. In the modern marketplace, spontaneous urges to buy and consume often compete with the practical necessity to delay the immediate gratification that purchasing provides. The purpose of this study is to conceptualize and test the framework of impulse buying behavior for fashion products using structural equation model. Data were obtained from 413 students attending universities during schedules classes in Busan. Analysis of the data, utilizing AMOS 4.1, supported most of the predictions. The results showed that situational variable(time available) and individual variable(fashion involvement) have direct effects on consumers' shopping emotions, including positive and negative emotion. Positive emotions had effects on all types of impulse buying(planned impulse buying, reminded impulse buying, and fashion-oriented impulse buying), while negative emotion affected two types of impulse buying(reminded impulse buying and fashion-oriented impulse buying). These emotional experiences influence impulse buying behaviors for fashion products serving as critical mediators. The findings suggest that time available and fashion involvement are good predictors mediated by shopping emotion to impulse buying behavior for fashion products. The implications of this research for future work on the shopping emotion and impulse buying behavior are discussed.

The purpose of this study was to investigate the components in friendship as reported by Korean children of School age Specially, four major aspects of friendship - definition of friendship, friendship formation, friendship expectation, and friendship termination were explored. The subjects of this study consisted of 600 elementary school children in Grades 1 through 6, 50 males and 50 females at each grade level. Based on Bigelow (1977) five open - ended questions were administered. First and second graders were interviewed individually while 3rd-6th graders replied to a questionnaire in class. For content analysis, responses of each child were coded into 22 categories and each category was assigned a score from 1 to 4 according to its frequency. The data were analyzed by factor analysis. The results showed that four major aspects of friendship in Korean children of school age were found to consist of four different factors. DEFINITION OF FRIENDSHIP was found to consist of the factors; 1) reciprocity of liking vs. helping 2) global evaluation vs helping 3) sharing and 4) common activities. FRIENDSHIP FORMATION was found to consist of the factors; 1) situational effects vs complex evaluation 2) structural dimension vs common activities 3) helping and 4) staring. FRIENDSHIP EXPECTATION was found to consist of the factors; 1) mutuality 2) common activities vs. loyalty & commitment 3) exclusive - dyadic activities vs. admiration (character) and 4) interactive a1truism. FRIENDSHIP TERMINATION was found to consist of the factors; 1) physical separation vs disappointment (character) 2) conflict 3) physical separation vs. psychological dimension and 4) general altruism.

According to the defense-in-depth concept, not only a preventive strategy but also an integrated cyberattack response strategy for NPPs should be established. However, there are limitations in terms of responding to penetrations, and the existing EOPs are insufficient for responding to intentional disruptions. In this study, we focus on manipulative attacks on process data. Based on an analysis of the related attack vectors and possible attack scenarios, we adopt the Kalman filter to detect process anomalies that can be caused by manipulations of process data. To compensate for these manipulations and secure MCR operators' situational awareness, we modify the Kalman filter such that it can filter out the effects of the manipulations adaptively. A case study was conducted using a hardware-in-the-loop system. The results indicated that the developed method can be used to verify whether the displayed safety-related state data are reliable and to implement the required safety response actions.

Training and process analysis in the construction industry has not taken full advantage of new technologies such as building information modeling(BIM). The purpose of this research is to develop a framework for the virtual interactive construction education system using three dimensional technologies. The modules will simulate the construction process for a facility from start to finish using information drawn from real projects in the built environment. These modules can be used as training tools for new employees where they attempt to optimize time and cost in a virtual environment given a limited number of equipment, time and employee options. They can also be used as a process analysis tool for new construction where a number of situational variables can change leading to exposure of potential risk. These modules would be particularly useful for repetitive construction where the initial project is analyzed for optimization and risk mitigation. This paper describes the framework and shows a residential construction example using a 900 square foot wood frame single family house designed for the United States.

Objectives: This study analyzed the education participation reasons and deterrents of dietitians who work in welfare facilities for the elderly. Methods: The survey was completed by 144 dietitians working at welfare facilities for the elderly in Korea. The survey was conducted in October, 2018, both on-line and off-line, based on the demographic characteristics, work status on welfare facilities for the elderly, Participation Reasons Scale (PRS) and Deterrents to Participation Scale (DPS-G). The data were analyzed using frequency analysis, descriptive analysis, factor analysis, reliability analysis, regressive analysis using SPSS ver. 25.0. Results: The reason for participation were divided into three factors: 'Responsibility of professional and self-development ($5.76{\pm}1.04$)', 'Job stability and personal benefits ($4.98{\pm}1.28$)', and 'Interaction and development of professional competencies ($5.85{\pm}1.00$)'. 'Interaction and development of professional competencies' was the highest motivation factor. Also, the deterrents for participation were divided into four factors: 'Dispositional barrier ($2.70{\pm}1.29$)', 'Dissatisfaction of education usability ($3.39{\pm}1.38$)', 'Institutional barrier ($4.21{\pm}1.45$)', and 'Situational barrier ($2.36{\pm}1.30$)'. 'Institutional barrier' showed the highest deterrents factor. In addition, 'Responsibility of professional and self-development' and 'Interaction and development of professional competencies' were negative attributes for 'Dispositional barrier' (p<0.001). Conclusions: These results provide basic data to promote participation in education and contribute to the improvement of their job ability and education capacity of the food and nutrition management of welfare facilities for the elderly.

본 연구는 해상교통관제사(이하 'VTS 관제사')의 해상교통관제(Vessel Traffic Service: 이하 'VTS') 수행 속성을 상황인식(situation awareness: 이하 'SA')과 관련된 세부 과제들의 수행 빈도와 SA 역량에 대한 주관적 평가의 측면에서 살펴보기 위해 실시되었다. SA 세부 과제들에 대한 수행 빈도 자료는 3개 VTS 센터의 VTS 관제사가 보인 VTS 수행을 직접 관찰하여 수집하였고, SA 역량에 대한 주관적 평가 자료는 18개 VTS 센터에서 근무하는 VTS 관제사를 대상으로 설문조사법을 통해 수집하였다. 수행 빈도 자료는 SA의 세 수준과 각 세부 과제에 따라 비교하였고, 주관적 평가 점수에 대해서는 VTS 관제사의 성별과 근무경력을 추가적으로 고려하여 분석하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, VTS 관제사는 SA 수준 중 정보지각에 해당하는 과제를 가장 높은 비율로 수행하였고, 이어서 정보통합과 예측에 해당하는 과제들을 각각 유사한 수준으로 수행하는 것이 관찰되었다. 둘째, VTS 관제사는 정보를 획득하거나 통합하는 역량에 비해 미래 상황을 예측하는 역량을 상대적으로 더 낮게 평가하였다. 셋째, 성별 차이를 비교한 결과, 남성 VTS 관제사는 여성에 비해 더 높은 수준으로 자신의 SA 역량을 평가하였다. 넷째, 성별로 근무경력에 따른 주관적 평가 차이를 비교한 결과, 남성의 경우 근무경력이 15년 이상인 VTS 관제사는 5년 미만의 VTS 관제사에 비해 SA의 모든 수준에 걸쳐 상대적으로 더 높은 주관적 평가를 보였으나, 여성의 경우는 근무경력에 따른 주관적 평가에서의 차이가 관찰되지 않았다. 이러한 결과는 VTS 관제사의 SA 과제 수행 빈도와 SA에 대한 주관적 평가가 SA 수준과 개인차 변인에 따라 달라질 수 있음을 시사한다.

This study was done to analyze the trends of research on coping in Korea, to suggest future direction, for research on coping, and ultimately to contribute to an increase in explanation of adaptation. This article reviewed 79 nursing research papers on coping done since 1978 by examining them according to the period of publication or presentation, research design, type of subjects, measurement instruments, research for a degree or not, range of reliability, and association of coping and related variables. The results are as follows : The number of studies on coping increased rapidly from the mid-1980's and decreased slowly from the mid-1990's. The maority of the studies were surveys, comparative studies, or correlational studies. The subects of the 46 studies were healthy people, while those in the remaining studies were patients with a variety of illnesses. Thirth-eight studies on coping were done for master's thesis, three for dissertion, and 38 were not degrees. The Bell and Jalowiec coping scales have not been used since the early 1990's. In contrast, Lazarus and Folkman's W.C.C.L. has been used increasingly since that time. The reliabilities of the coping scale were reported in 37 cases and the Cronbach's alpha coefficients were .71 to .86. All subjects reported using more problem-oriented coping than emotion-oriented coping in short-term or emotion-oriented coping and healthy groups did more long-term coping. It was difficult to describe consistently the relationship between stress and coping according to the type of coping scale or research subjects, but generally moderate relationships were found. This was due to instrumental problems and no consideration of situational context. The subject group who used more short-term coping and less long-term coping reported poorer mental status, and higher scores in burnout and state anxiey than others. That is, the relationship between stress and adaptation increased the power of explanation with intervening the mediating effect of coping. The association of locus of control, mastery, social support, and self-concept with coping showed positive relationships : those of uncertainty and severity in illness with coping showed negativerelationships ; those of state anxiety and depression with short-term coping were positive, and those of self-esteem with long-term coping or problem-oriented coping were negative. There were significant differences in the scores of types of coping according to religion, level of education, and socio-economic status. That is, Presbyterians and Catholics, those with higher education levels and higher socio-economic status used more long-term or problem-oriented coping. On the basis of the above findings the following recommendations are made : 1. There is a need to test the mediating effect of coping variable in order to clarify the concept. 2. Longitudinal studies are needed to determine the patterns of change in coping strategies when stressful events are encountered. 3. It's necessary to develop a reliable and variable measurement tool for coping. 4. There is a need to identify subscales of coping to increase explanation of variance 5. It's necessary to consider personal, situational, and antecedent variables : the characteristics of subject populations, the natures of illness and treatment situations. 6. The power of explanation of studies designed to identify the stress-adaptation process should be increased using the combination model of process-oriented coping and cognitive-structural model.
