In this study, we propose a statistical model based on projection that generates interview scores. In this model, each interviewee's true score and its related variable are viewed as X, Y values respectively in the two dimensional plane, and each interviewer's score is the projected score of true score X to the axis rotated by some angle, which reflects the interviewer's perspective. Each interviewer's observed interview score is obtained by adding personal bias and observed error to this projected score. We compared commonly used standardizing methods of interview scores such as trimmed mean method, rank method, and z-score method based on the proposed statistical model. In this simulation, two types of interview methods, two numbers of interviewers, two degrees of interviewers' expertise and two distributions and three correlations between actual score and its related variable are all considered.

Along with the government's policy to encourage youth entrepreneurship, each university is making great efforts to promote entrepreneurship, and university entrepreneurship programs can be said to be the most important part of supporting and activating college students' entrepreneurship. In order to increase interest in and participation in entrepreneurship and entrepreneurship programs, it is necessary to take an in-depth look at students' perceptions of entrepreneurship and entrepreneurship programs. Therefore, this study used the effectiveness hierarchy model to explore the perceptions of college students at each stage and to identify bottleneck factors that hinder participation in entrepreneurship programs. For this purpose, focus group interviews and in-depth interviews were conducted using samples with different levels of interest and participation in entrepreneurship and entrepreneurship programs, and bottleneck factors at each stage of the effect hierarchy model were presented. The research results complement entrepreneurship research that was focused on quantitative research, and add important practical implications by approaching the study with a particular focus on local university cases.

The aim of this study is to examine effects of a yoga program for children on school stress of the elementary school children. To achieve this goal, total 10 students out of 231 in 6 classes among the third graders in M elementary school in B city were selected as subjects for this study. After regular school hours, they participated in a children's yoga program for 16 times for 45 minutes per session in the course of 8 weeks. An ethnographic interview was conducted to identify the effects of the program. During the initial stage of the children's yoga program, the participants were interviewed preliminarily. An analysis of areas and an analysis of classifications were made based on the initial interview results, and an area classification table was drawn on the school stress perceived by the elementary school children. After the yoga program ended, a follow up interview was made to apply an analysis of components by comparing changes in the school stress level due to a yoga effect. A research report was written through a cycle of addition and supplement in which the previous data analysis was complemented and corrected by new findings of the study. As a result of the ethnographic interview to analyze the school stress perceived by the elementary school children, and an examination of the changes in the school stress level, the children's yoga program proved to be significantly effective in reducing the school stress. However there were limitations to a certain degree in stress reduction. Details of such findings in each sub-category are as follow. First, as a result of the initial interview analysis, the school stress was classified broadly into 4 categories of study stress, friendship stress, teacher stress, and school environment stress. Second, the study stress as the first category of the school stress was classified into 3 sub-categories of homework, class, and exam stresses. In spite of minor differences among 3 sub-categories, the stress was reduced in general. Third, the friendship stress as the second category of the school stress was also classified into 3 sub-categories of bullying, alienation, and performing one's duty. There were minor differences among sub-categories, however stress reduction also appeared with the exception of the performing one's duty category which had relatively little effect from the yoga program. Fourth, regarding the teacher stress as the third school stress, a classification was made into 3 sub-categories of preference, penalty, and teaching method. Minor differences among the 3 sub-categories notwithstanding, stress reduction appeared with the exception of the teaching method stress which had relatively little effect from the yoga program. Fifth, the school environment stress as the fourth category of the school stress was classified into 2 sub-categories of school meals and facilities. Minor differences between the 2 categories notwithstanding, stress reduction appeared with the facilities stress having relatively little effect.

The purpose of this study was to analyze the generating processes of scientific emotion, that appears during the generation of biological hypotheses. To perform the study, a tentative model was set up through pilot test, a think-aloud training procedure was planned and a standardized interview instrument was developed before getting protocols. In this study, 8 college students were selected to bring out protocol through the method of think-aloud, retrospective debriefing, focused interview and observing. As the result of analysis of the collected protocol through coding scheme, 4 types of process for scientific emotion-generating were sorted out. First type was a basic process which was a feeling process in prior to recognition. Second type was a retrospective process that explains the process of retrospect for emotional memory based on the past. Third type was a cognitive process and it explains emotion that occurs during thinking process to achieve cognitive goal. Fourth type was an attribution process and it explains that emotion is generated in the process of attribution for cognitive goal's achievement. These types of process of scientific emotion-generating can contribute the basis for developing cognitive model of EBL (Emotional Brain-based Learning) strategy.

Excessive consumption, pollution, and am expanding global population are seen as very important issues that must be solved through reusable materials and the reduction of energy consumption. This study examines the values and design elements such as line, color, and textures in eco-friendly fashion that could contribute to the product development of an eco-friendly brand. The following methods of analysis were used in this study. An in-depth interview (where the interviewer records the response of interviewers to questions) was used to grasp the diverse design properties of products that customers need or want and the recorded interviews were documented by computer using open coding. The results show that the personal, economic, and social value of eco-friendly fashion has increased, in addition to the environmental value. The needs and preference of customers for eco-friendly fashion design were diversified and the consumer consciousness was more advanced than the consciousness of experts. This shows that it is not enough to consider the effect on the environment. In conclusion, understanding the personal, environmental, economic, and social value from the viewpoint of customers, finding the optimal design factors, and reflecting them in the development of products are necessary for advanced eco-friendly fashion.

본 연구에서는 도시, 농촌, 어촌지역 주민들의 주거만족도와 지역사회 및 생활환경 만족도를 비교 측정하고자 하였다. 이 연구의 특성은 지역을 하나의 통제변인으로 분석에 포함시켜 제변인들의 영향력의 방향과 정도를 파악하고자 하였다는 점이다. 자료는 1993년 6월 부터 1994년 6월 동안 488명의 주부를 대상으로 수집하였으며, 대구에 거주하는 주부 254명과 경북권내의 영천과 청도 등의 농촌지역에 거주하는 주부 124명, 그리고 한산도 섬내에 거주하는 주부 110명을 대상으로 각 가정을 방문하여 면접법을 실행하였다. 회귀분석을 실행한 결과, 주거만족도에 영향을 미치는 변인은 주거비와 주거소유형태였으며, 거주하고 있는 지역사회와 생활환경에 대한 만족도가 증가할수록 주거만족도도 증가하는 것으로 나타났다. 지역을 고려할 때, 도시거주자의 주거만족도가 농촌이나 어촌거주자의 주거만족도 보다 높은 반면 지역사회에 대한 만족도와 생활환경 만족도는 농촌거주자와 어촌거주자가 도시거주자보다 더 높은 것으로 나타났다. 본 연구의 결과는 지역을 고려한 주거정책 관련 프로그램 개발을 위한 기초자료로 이용될 수 있으리라 사료된다.
