BRIS has been established by the Ministry of Agriculture, Food and Rural Affairs since 2011 under Article 21 of the Act on the Preservation, Management and Utilization of Agricultural Life Resources. It is an information service that provides information related to agricultural life resources in connection with the Rural Development Administration, the Forest Service, and Korea Seed & Variety Service, Agricultural Resources and Agricultural and Livestock Quarantine Headquarters. The purpose of this study is to evaluate how the users assess the information system quality (information quality, system quality) for the current Bio Resource Information Service (BRIS). Ultimately, the structural equation modeling analyzes the causal relationship between each variable and how it responds to the user's continuous use intention. As a result, information quality among information system quality and information quality among system quality used as the main variables for the evaluation of BRIS were statistically positively influenced by users' perceived usefulness, while system quality It has been analyzed to have a positive effect on the sustained use intention. The user's continuous use intention is positively influenced by the information system quality and perceived usefulness at a statistically significant level. Especially, the perceived usefulness plays a role in mediating the user's continuous use intention.

The purpose of this study was to examine the mechanism through which Senior Center User's services satisfaction impacts quality of life. We were particularly interested in the mediating effect of empowering Senior Center users. bootstraping method based on structural equation modeling were used. The partial and full mediation model were compared and X² difference test was conducted between the two models. The result showed that the mediating effect of empowering senior center user was statistically significant and accounted for the relationship between the senior center user's services satisfaction and quality of life. Empowering senior center user mediated fully the effect of senior center user's services satisfaction on quality of life. Practice and policy implications as well as further research topics were discussed to aid the search for highly effective interventions.

According to the development of information technology, there are many services in our life. These services make our life safe and convenient. However, the increment of the services also causes the increment of human concern and effort to control these services. The context-aware service is the service that provided their functionality at the right time and to the right place by analysis user's current situation. The most previous studies about context-aware service regard that context-aware services are defined by the developer who has expertise in information technology. The definition of the context-aware services by the developer makes difficult to reflect user's personal preferences and life pattern to the services. In this paper, we propose an user interface EUCAS(by End-User, Context-Aware Service development) that make the user can define and manage their own context-aware service according to their preferences. We expect EUCAS can be effective user interface technology for providing personalized context-aware service.

The purpose of this paper is to study renovation plan of value chain from a user's viewpoint by making practical application of digital technology in Korea and China. And it is surely meaningful to investigate the important motivation factors of continuous using smart-phone in two countries, and to analyze the improving effect toward to the quality of life in continuous using smart-phone. By this study we can expect the value improving effect of user experience. The results of hypothesis testing can be summarized as follows: First, the hypothesis that positive affect has a plus effect on pragmatic value is accepted in Korea and China. Secondly, the hypothesis that positive affect has a plus effect on hedonic value is accepted in two countries. Thirdly, the hypothesis that negative affect has a minus effect on pragmatic value is accepted in Korea, but rejected in China. Fourthly, the hypothesis that negative affect has a minus effect on hedonic value is accepted in two countries. Fifthly, the hypothesis that pragmatic value has a plus effect on life satisfaction is rejected in two countries. Sixthly, the hypothesis that hedonic value has a plus effect on life satisfaction is accepted in Korea, but rejected in China. Seventhly, the hypothesis that there is a difference in positive affect, negative affect, pragmatic value, hedonic value and life satisfaction between Korea and China is rejected in positive affect and negative affect, but accepted in pragmatic value, hedonic value and life satisfaction. In the competition among enterprises, user experience instead of goods themselves became influential as a differential factor. And many advanced enterprises began taking a serious view of customer's happiness and user experience improvement.

Usability assessment has been installed into a wide range of software that focuses on assessing product usage from the user's perspective. Usability assessment of the quality of life technology for individuals with disability is being discussed and tentatively designed which is also expanded to the products for non-disabled people with minor adjustment of the usability assessment protocol. Designing an appropriate usability assessment protocol by referencing the currently available international standards on software usability tests with number of modifications to produce valuable feedbacks is under evaluation process regarding product usability enhancement. The feasibility study on usability assessment protocol into quality of life technologies is presented with discussions on further research.

By taking a bottom-up "library in the life of the user" perspective rather than a top-down "user in the life of the library" perspective, this paper uses anecdotal evidence from the past and near present to examine the multiple roles the U.S. public library plays and has played as public space in the everyday lives of its patrons. By harnessing "public sphere" theory discussed in Jurgen Habermas's THE STRUCTURAL TRANSFORMATION OF THE PUBLIC SPHERE (1989) and by the examining the rich literatures on civic life and institutions that have evolved from it, the author argues that Library and Information Studies discourse has to expand its scope to include research and analysis of "library as place" from a user's perspective if it hopes to develop a deeper understanding of what the public library does for means to members of the communities in which they reside.

In this paper, we modeled a virtual life (VL) that reacts to the user s action according to its own behavioral characteristics and grows itself. We established some conditions with which such a VL is designed. Genetic Algorithm is used for the growth process that changes the VL s properties. In this process, the parameter values of the VL s properties are encoded as one chromosome, and the GA operations change this chromosome. The VL s reaction to the user s action is determined by these properties as well as the general expectation of each reaction. These properties are evaluated through 5 fitness measures so as to deal with multi-objective criteria. Here, we present the simulation of the growth Process, and show some experimental results.

Personal mobile devices such as mobile phone, PMP and MP3 player have advanced incredibly. Such advance in mobile technology ignites the research related to the life-log to understand the daily life of an user. Since life-log collected by mobile sensors can aid memory of the user, many researches have been conducted. This paper suggests a methodology for user-context recognition and visualization based on the outdoor location by GPS as well as indoor location by wireless-lan. When the GPS sensor does not work well in an indoor location, wireless-lan plays a major role in recognizing the location of an user so that the recognition of user-context become more accurate. In this paper, we have also developed the method for visualization of the life-log based on map and blog interfaces. In the experiments, subjects have collected real data with mobile devices and we have evaluated the performance of the proposed visualization and context recognition method based on the data.
