쇼핑, 음악, 영화 등 오프라인에서 즐기던 많은 서비스가 이제는 온라인화 되어 일상화되었다. 그 중 뉴스의 경우도 미국의 리서치업체가 조사한 결과에 따르면, 인터넷 사용자의 21%가 온라인 뉴스를 오프라인보다 더 선호할 뿐만 아니라 온라인에 대한 선호도가 비약적으로 늘고 있다고 밝혔다. 종이 페이퍼로 뉴스를 제공할 때는 정보를 제공하는 공간이 제한적이기 때문에 사용자의 행위를 어느 정도 예상할 수 있다. 그러나 상대적으로 온라인 뉴스와 같은 컨텐츠 서비스는 하이퍼텍스트를 기본으로 하기 때문에 사용자의 패턴을 정확히 파악하기가 쉽지 않다. 컨텐츠 서비스 사용 행위를 분석하기 위해 아이트랙킹, 인뎁스인터뷰 등 여러 방법론을 적용할 수 있으며, 아이트랙킹 연구는 Poynter Institute 에서 2004년도에 진행한 사례가 있지만 여전히 컨텐츠 서비스에서의 핵심 이슈인 컨텐츠 영역에 대한 관심도, 영역별 연관성 파악 등에 대한 객관적 데이터가 부족하다. 따라서 본 논문은 컨텐츠 서비스 사용자의 유저 시나리오 도출을 위해 온라인 뉴스를 대상으로 한 분석 케이스를 소개한다. 본 사용자 행동 분석 리서치 수행을 위해 원격툴을 개발하였으며, 이 툴을 실제로 적용해봄으로써 컨텐츠 서비스 분석시 가능성과 고려사항들을 함께 살펴본다.

In mobile computing research area, it is highly desirable to understand the characteristics of user movement so that the user friendly location aware services could be rendered effectively. Location based social networks (LBSNs) have flourished recently and are of great potential for movement behavior exploration and datadriven application design. While there have been some efforts on user check-in movement behavior in LBSNs, they lack comprehensive analysis of social influence on them. To this end, the social-spatial influence and social-temporal influence are analyzed synthetically in this paper based on the related information exposed in LBSNs. The check-in movement behaviors of users are found to be affected by their social friendships both from spatial and temporal dimensions. Furthermore, a probabilistic model of user mobile behavior is proposed, incorporating the comprehensive social influence model with extent personal preference model. The experimental results validate that our proposed model can improve prediction accuracy compared to the state-of-the-art social historical model considering temporal information (SHM+T), which mainly studies the temporal cyclic patterns and uses them to model user mobility, while being with affordable complexity.

This study aims to clear the relation between perceived risk and user's attitude and behavior toward a food service event. To accomplish this, theoretical reviews and empirical analysis were jointly carried out. For the empirical analysis, a survey was conducted from April 3 to April 6, and total 291 copies of the questionnaire were used for the statistical analysis, SPSS 15.0 and LISREL 8.30. The results of the test of the hypotheses can be summarized as follows: First, the analysis shows that there is significant difference between the perceived risk and attitude of a food service event user. The perceived risk of food service event users causes effect that is contradictory in attitude. As users' perceived risk is less, attitude improved. Second, the analysis of the relationship between user's attitude and behavior intention showed that user's attitude affected behavior intention. Therefore, under these circumstances, there should be more concern in solving perceived risk among food service event users and a special program for promoting satisfaction with an event. And food service event director should make more efforts in nutritive value, organic food, time saving, etc.

The purpose of the study was to discuss amrketing strategy for oriental hospital, by making a comparative analysis of how hospital user satifaction was affected by hospi시 choice motivation between oriental hospital users and western hospital. The data usel in this study was the Korea Isititute of oriental medicine(1999)'s study on utilization of oriental medical care. And and interview was hold with outpatients who visited around march to April, 1999, at each an oriental hospital and a westen hospital in Seoul and in Wonju city, Kongwon province. The collected data were analyzed by SPSS program. The factor analysis of hospital choice motivation was made by figuring out facor's mean value, and T-test and ANOVA were employed to find out what difference was made by sociodmographic charcteristics to the factors. Also, the multiple regression analysis was carried out to examine what gave an impact on hospital user satisfaction. The findings of this study were as follows; First as a result of making a factor analysis against hospital choice motivation to find out what kind of differenc there was between oriental hospital user motivation and western hospital and person factors. Among them, the hospital charcteristics, preception, personal and person factors. Among them, the hospital charcteristics appered to have the biggest effect of hospital choice motivation. Second, as a result of making comparison between oriental oriental hospital user satisfaction and werterm hospital user satisfaction, there was a singificant between their satisfaction at treatment time, kindness and relative kiness aginst the pther hospital. The oriental level combining 6 items. The geneal satisfaction level combining 6itmes tured out to have reliability of chronbach $\alpha$=0.7126. As a result of examining how mech the general satifaction level depended on sociodemographic characteristics, ther was found be significantly affected by age, marital status, educational background or hospital type. Those who a spouse or a lower educational background or the oriental hospital users got better score. Third, the multiple regression analysis was made to find out what factors affected western and oriental hospital user satisfaction, As a result, the waiting time, experience of other medical facilities and hospital characteristic variable were identified as a key factor on which westerm hospital user satisfaction depended. In conclusion, the oriental hhspital user expressed more staisfaction than the weshren hospital users. Then the characteristic factor played a singificant role in user satisfaction, which included hospital facilities, kindness of herb doctor and employees, or hospital reputation of credibility. in order to raise hospital user datisfaction, it seemed necessary to pay more attention to hospital characteristic factor rather than to perception factor.

The growth in smartphone service has given rise to an increase in frequency and importance of authentication. Existing smartphone authentication mechanisms such as passwords, pattern lock and fingerprint recognition require a high level of awareness and authenticate users temporarily with a point-of-entry techniques. To overcome these disadvantages, there have been active researches in behavior-based authentication. However, previous studies focused on enhancing the accuracy of the authentication. Since authentication is directly used by people, it is necessary to reflect actual users' perception. This paper proposes user perception on behavior-based authentication with feature analysis. We conduct user survey to empirically understand user perception regarding behavioral authentication with selected authentication features. Then, we analyze acceptance of the behavioral authentication to provide continuous authentication with minimal awareness while using the device.

The purpose of this study is to provide empirical and quantitative analysis on user's perceived privacy, security, and user satisfaction when providing visualization information about objects and service provider behaviors that users can not perceive in internet service process. Through previous research, we have examined the importance of privacy and security factors as a key factor to be considered for the characteristics of the Internet of things and the Internet of things. In addition, service blueprint, which is one of the service design methodologies to examine the flow of service usage in providing Internet service of things, was examined. In the flow of things internet service utilization, it is found that the things that are out of the user's cognitive area and the behavior of the service provider take up a large part. Therefore, the hypothesis that the trust of the Internet service security and the satisfaction of the user experience can be improved by providing the security visualization information about the behavior of the object and the invisible service provider in the non-contact aspect of the user and the object. In order to verify the hypothesis, we conducted experiments and questionnaires on the use of virtual objects' internet environment and conducted statistical analysis based on them. As a result, it was analyzed that visual information feedback on non - contact and invisible objects and service provider's behaviors had a positive effect on user's perceived privacy, security, and satisfaction. In addition, we conclude that it can be used as a service design evaluation tool to eliminate psychological anxiety about security and to improve satisfaction in internet service design. We hope that this research will be a great help for the research on application method of service design method in Internet environment of objects.
