인터넷 서비스의 급속한 발전으로 멀티미디어 데이타의 양이 크게 증가함에 따라, 이를 분석하여 유용한 정보를 얻기 위해 사용자 개개인에 초점을 맞춘 효율적인 검색기술이 필요하게 되었다. 하지만 최근 웹사이트에서 제공하는 사용자 모델링 서비스는 텍스트 기반 페이지 구성이나 추천 검색 등에만 국한되어 있는 단점이 있다. 본 논문에서는 사용자 모델링 기법을 동영상 검색에 적용하기 위해 사용자의 선호도를 베이지안 네트워크로 모델링하고, 추론된 확률 값을 검색에 반영하는 방법을 제안한다. 이를 위해 실제 연구실 환경 내에 존재하는 컨텍스트 정보를 정의하였고, 설치된 카메라로부터 얻어진 동영상이 포함하는 컨텍스트 정보를 텍스트의 형태로 주석을 달았다. 사용자로부터 입력받은 사용자 개인의 정보는 설계된 베이지안 네트워크 모델의 증거 값으로 사용되어, 그로부터 사용자의 선호도를 추론하도록 하였다. 베이지안 네트워크의 추론 결과로 얻어진 확률 값은 검색에 반영되어 각 사용자의 선호도에 맞는 검색 결과를 보여준다. 사용자 평가 결과, 제안하는 모델을 사용하여 선택된 결과의 만족도가 일반적인 검색의 결과에 비해 높음을 확인하였다.

Purpose - The purpose of this study is to grasp the concept, characteristics and application status of sharing economy, and to derive a research model based on sharing economic service, and to analyze factors and influences of consumers' intention to reuse of sharing economy. Research design, data, and methodology - The questionnaires were created to examine variables for practical and theoretical implications. After pilot survey, conducted for 24 days from March 10th to April 2st in 2017, total numbers were 377. But 330 copies were used for the analysis with IBM SPSS Statistics 23.0 and IBM SPSS AMOS 23.0. The structural equation model was applied for this. Results - First, sharing economic services remain at an early stage, but it is meaningful to identify the revenue mechanism of the business model of the sharing economic platform. Second, in this study, it is meaningful that we systematized the theoretical structure by examining existing studies on the characteristics of the sharing economic service and consumer characteristics, and by examining empirically. Third, Satisfaction and Reliability are related to the characteristics of Sharing Economic Service (Security, Convenience, Discount, Sharing, Social Interaction), Consumer Characteristics (Personal Innovation, Word-of-Mouth) It is meaningful to broaden the understanding of the factors by verifying the mediating effect. Fourth, the sharing economy business is meaningful in that it is a new consumption trend that changes the meaning of consumption to consumers. Gradually, more and more people are recalling that purchasing something is not consumption, but sharing and borrowing is also consumption. In other words, through the sharing economy, consumers can experience more products and services, have more choices, and are expected to have a positive impact on economic growth by increasing the utilization of idle resources. Conclusions - Currently, the sharing economy is growing rapidly all over the world. Therefore, in the subsequent study, it is necessary to compare Korea and China's sharing economy and study the cultural and social characteristics of Korea and China. In particular, I think that steady research is necessary for more precise and specific direction on the influence of the shared economy.

This study investigated the influence of obesity on depression and stress by analyzing the results of the national survey on health and nutrition. Relationships between normal, obese, and severely obese groups were investigated. The results of the study are as follows. First, obesity caused by demographic variables showed a relationship to both gender and average monthly income. In the case of the seriously obese group, females had higher rates of depression than males, and the high obesity group had lower average monthly income than the normal and obese groups. Second, obesity caused by health-related variables found that high blood pressure, hyperlipidemia, and diabetes that was not angina-related displayed higher rates of depression in the serious obesity group than in the other groups. As for subjective evaluations of one's own health condition, the serious obesity group showed a high tendency to evaluate their own health conditions negatively. Third, the difference between depression and stress related to obesity level showed no difference between the normal weight group and the obesity group; however, the seriously obese group demonstrated relatively higher occurrences of depression and higher stress scores. Fourth, the result for depression and stress level caused by demographic variables, health-related variables, and obesity demonstrated a direct relationship to gender, subjective level of satisfaction with one's personal finances, average monthly income, subjective perception of one's own health and severely obesity status. More specifically, it was found that the ratio of depression and stress score was higher when the subject was female, among those whose subjective evaluation of their own finances and health condition was negative, and those who suffered from severe obesity.

Purpose: Healthcare is on the whole a personal and critical service that consumer's use, whereas hospitalization is as a rule painful, because nature nurtures and Sun Light Luminosity for healthcare settings is considered healing. The performance and design of climate responsive buildings such as AKU requires a detailed study of attributes of climate both at micro as well as macro level. The therapeutic value of contact with nature through window view, greenery and landscape is calculated there. Method: A two prong strategy is been devised for this article, at micro level three typical morphologies are analysed by creating same environment of neighboring building on sun shading chart, radiation and temperature range. Since the analysis of local climate helps to determine the design strategies for hospital Healing Environment which is suitable for Karachi climate; in order to track the macro climatic behaviour, a considerable analysis of psychometrics chart for AKU Karachi are designed on Climate Consultant (CC) and analysed by Machine Learning. Climate Consultant proposes different design strategies suitable for Karachi. And on the other hand time wise illumination sources for clinical area which are then measured on psychrometric chart- according to singular space: multi patient admission, secondly: acute ambulatory ward, and tertiary: multi windowed space according to the mushrabiyah and sky light pattern. Result: Our findings support the hypothesis that windowed wall is 75-80% more healing wall; an accelerated evidence was found for healing at macro level if the form of the hospital is designed according to the climatologically preferences, whereas at micro level: the light resource becomes the staff attentiveness determinant. In Conclusion evidence was provided that the actual form of luminosity results consequently in satisfaction while light entering from several set of windows and other sources might be valued if design according to the healing environment. The data added on the sun shading chart to calculate rays entraining into space in patient room equal to 124416.21 Watts/ meter $m^2$ is calculated as precise healing rate-and is confirmed by questionnaire from patients belonging from each clinical stage having different illnesses.

People tend to maintain and express their individuality in unique ways. Consumer's need for uniqueness is defined as an individual's pursuit that differentiates themselves from others, thereby developing and enhancing their personal identities. This study examined the effect of consumers' need for uniqueness on fashion orientation and consumption values. Data were collected through a questionnaire survey distributed to people visiting the fashion show center during Seoul Fashion Week. The survey questions were designed using the 5-point Likert scale and Cronbach's ${\alpha}$ value of questions was reliable as .628-.862. The study's results indicate that people with high need for uniqueness are very interested in fashion and think that is important to be well-dressed. In addition, the results suggest that people with high needs for unusual choices who enjoy challenging the prevailing taste of people want to be fashion leaders and are attracted to products that express their personality well. And people with high needs for creative choices and incompliant choices value their own satisfaction and happiness with the products. On the other hand, consumer's needs for incompliant choices have a negative effect on social value. As a result, people with high needs for incompliant choices would break social norms rather than consider social status and reputation when they purchase fashion products. The concluding section of the paper discusses the implications of this research for fashion companies.

The purpose of this study was to identify egocentrism, self-consciousness, and body cathexis between Boys' and Girls' high school students. It helps us to understand them. Also we investigated the correlation between psychological characteristics and clothing behavior of high school students. The questionnaire were administered to 630 boys' and girls' high school students living in Jinju, Gyeongnam, and the data were analyzed by Frequency, Factor Analysis, Pearson's Product Moment Correlation, ANOVA, Multiple Regression Analysis and Duncan test. Egocentrism of high school boys and girls showed middle levels of mean and distribution, and sympathy was the highest at coeducation high School whereas a sense of justice was the highest at boys' high school. Self-consciousness was high level at both boys' and girls' high school, but public self-consciousness was higher than personal one. Both of them were higher in girls' than in boys'. Also body satisfaction was a little high and boys satisfied with their faces, busts, and whole body more than girls. There were significant differences among dressing for others, clothing interest, psychological dependence, exhibition except conformity. Girls have dressing for others, clothing interest, and exhibition more than boys. There were significant positive correlations among dressing for others, clothing interest, psychological dependence, and conformity whereas exhibition was negatively related to clothing behavior. Public self-consciousness, appearance, and popularity were the most influential variables to dressing for others. Also gender was proved to be one of the most influencing factors on students' clothing behavior.
