As the mobile environment becomes widely used, there is a growth on the concern about recognizing and sharing user context. Sharing context makes the interaction between human more plentiful as well as helps to keep a good social relationship. Recently, it has been applied to some messengers or mobile applications with sharing simple contexts, but it is still required to recognize and share more complex and diverse contexts. In this paper, we propose a context-aware messenger that collects various sensory information, recognizes representative user contexts such as emotion, stress, and activity by using dynamic Bayesian networks, and visualizes them. It includes a modular model that is effective to recognize various contexts and displays them in the form of icons. We have verified the proposed method with the scenario evaluation and usability test.

This qualitative study is designated to explore the reality of social welfare related to the co-occurence of domestic violence and child maltreatment in Korea. "Alone and Together" is elicited as the main theme from the analysis of social workers' experiences with the co-occurence problem in the two fields of domestic violence and child maltreatment. Despite the fact that the social workers are aware of the co-occurence problem embedded in their field cases, they don't assess and intervene with the problem on set purpose. Each field has dealt with the problem according to the field priority for either women or children separately. However, the social workers in the both fields desire alternatives effective for their cooperation and linkage to each other when confronted with the intersection of interdependent needs and problem-solving for the woman and the child. The development of multi-level research, assessment tools, and compulsory education courses for practitioners related to the co-occurence problem is suggested.

The major findings are(were) as follows: 1) The Eco-friendly consumption behavior was divided into three(3) clusters, namely "The Middle Group" of eco-friendly consumption behavior(cluster I), "The Inferior group" of eco-friendly consumption behavior(cluster II), and "The Excellent Group" of eco-friendly consumption behavior(cluster III). 2) The differences in the general characteristics among the three clusters were founded on the experience of green consumption information and sources of information. 3) The characteristics of cluster I(The Middle Group) were(are) found to be eco-conscious, and aware of the consequences of behaviors, green market conditions and environmental issues. This cluster was the middle-average group. The characteristics of cluster III(The Excellent Group) were(are) found to have the willingness to pay additional costs, being aware of the social norms of the reference group, having an awareness of eco-institutional conditions, being knowledgeable about environmental policy, and finally, being personally involved in green consumption behavior. This cluster was the high-average group, whereas cluster II(The Inferior Group) was the low-average group.

In this paper, we propose a personalized event recommendation scheme using user's activity analysis and collaborative filtering in social network environments. The proposed scheme predicts un-evaluated attribute values through analysis of user activities, relationships, and collaborative filtering. The proposed scheme also incorporates a user's recent preferences by considering the recent history for the user or context-aware information to precisely grasp the user's preferences. As a result, the proposed scheme can recommend events to users with a high possibility to participate in new events, preventing indiscriminate recommendations. In order to show the superiority of the proposed scheme, we compare it with the existing scheme through performance evaluation.

In this paper, we consider mobile ad hoc network routing protocols with respect to content sharing applications. We show that by utilizing social relations among participants, our routing protocols can improve its performance and efficiency of caching. Moreover, in certain situation which we can anticipate pattern of user's content consumption, our scheme can help such applications be more efficient in terms of access time and network overhead. Using NS2 simulator, we compare our scheme to DSDV and routing protocol using shortest path algorithm.

Coupled schemes between service-oriented architecture (SOA) and Web 2.0 have recently been researched. Web-based content providers and telecommunications company (Telecom) based Internet protocol television (IPTV) providers have struggled against each other to accommodate more three-screen service subscribers. Since the advent of Web 2.0, more abundant reproduced content can be circulated. However, because according to increasing device's resolution and content formats IPTV providers transcode content in advance, network bandwidth, storage and operation costs for content management systems (CMSs) are wasted. In this paper, we present a user centric CMS for open IPTV, which integrates SOA and Web 2.0. Considering content popularity based on a Zipf-like distribution to solve these problems, we analyze the performance between the user centric CMS and the conventional Web syndication system for normalized costs. Based on the user centric CMS, we implement a social Web TV with device-aware function, which can aggregate, transcode, and deploy content over social networking service independently.

This study was conducted to investigate priority recognition of experts and related facility operators in establishing policies for revitalizing agro-healing services. After reviewing related studies, 5 policy division and 19 detailed sector were drawn, including improving accessibility, improving promotion and information provision method, improved public relations and information provision, diversification of facility and program, financial support, and expansion of expert and specialized institutions. A questionnaire survey was conducted on agro-healing experts, agro-healing facility operators, social welfare experts, and social welfare facility operators. The AHP analysis indicated that agro-healing experts and facility operators had the highest priority in the division of expansion of expert and specialized institutions, while social welfare experts and facility operators had the highest priority in financial support. The IPA analysis was conducted to identify the priority of each policy sector. Respondents recognized above normal importance to policy divisions, but were relatively aware of the importance of improving accessibility, with overall satisfaction level appearing to be moderate. The results of this study are expected to provide useful information for establishing agro-healing policies and for establishing effective strategies.

Purpose: Since 2006, social, ethical, and institutional options have been attempted in Korea to establish research ethics; however, the effectiveness of these attempts has not been thoroughly examined. Studies have been conducted abroad to determine the timeliness of social, ethical and institutional alternatives, such as the adoption of laws governing research ethics, the improvement of research ethics education, the bolstering of systems, the introduction of incentive programs, and the creation of social environments that support research ethics. Research design, data, and methodology: Specific facets of research misconduct or research ethics must be investigated and verified. Aspects of moral growth at the person level must be investigated via research ethics and research ethics education. Results: There is an increasing need for the general public to define and uphold research ethics as the impact of research findings on society grows. Researchers can boost their confidence in their ethical judgments and actions by being aware of research ethics. This may lead to confidence in their capacity to make morally sound decisions. Conclusion: By doing this study, the researcher confirmed that ethically correct behavior can lead to and realize self-growth. Researchers may be more interested in and dedicated to their work when they feel that their research might help them mature and develop ethically.
