This study is aimed to examine the characteristics of library space, in which user experiences and social networking are central in its design. Today, a library is a place to provide diverse accesses and experiences to information networks, where various individuals and user groups come and share mutual understanding and experiences. Library users developed social ties and a sense of community through library experiences. As a multipurpose space of a community, a library has the characteristics of urban public space like sidewalks and plazas. The eight case studies of libraries are analyzed from the viewpoint of each factor of library experience, including landscape, sidewalk, and plaza experience. The study drew its conclusions as follows. First, a library is a regional landmark for the users. Thus, it tends to be designed to allow transparency on its surface which introduces inner and outer landscape into the inside of the building. Second, the users experience a library similarly as they experience an urban street where they interface, browse, and interact with people and information. As they interact and share experiences, they develop solidarity and social ties among them. A library is designed to preserve continuity to adjacent streets, which increases accessibility to the building and hosts street activities into the building. Third, a library today is designed to be a flexible open space with information networking as well as community networking which allows library users diverse activities within it. For example, a multipurpose grand stairs in the middle of the main circulation of a building allows the users diverse activities. A large open stack with reading areas gives the users the feeling of an urban plaza where they can move vertically and horizontally. In conclusion, all findings of this study imply a user-oriented design for a library building.

This study examines the perception and its meaning of child education and mother]s role for children of Korean mothers for their children to study abroad in Malaysia. For this purpose, data was collected through in-depth interviews with seven mothers and one grandmother. All participants were lived in Malaysia for at least 6 months above. As a result, the most of recommenders of studying in Malaysia were fathers. And the purposes of studying in Malaysia were the improvement of their children's English learning skills and abilities, and not-good academic achievement in Korea. They made a decision for their children to study in Malaysia in that it was good to study in Malaysia for early 'spec' management for their children. But in the case of Korean mothers, they had a diverse desires internally. For example, they had a desire to escape from the relationships with mother-in law or complicated social relations of their family, kin, and neighbors in Korea. In Malaysia, Koran mothers carried out their roles of children's time management, information network management and 'distinction' strategies to their friends and neighbors for their children to study well and up their achievements' levels. Lately, they had planning to develop for their children's long term life design and their choices of universities in Korea, with special reference to the various connections of school-ties and religion-ties in Malaysia.

As the postsecondary school-age population continues to decline, universities are building identities to differentiate themselves and create a favorable impression among this cohort. We investigated the role of logo-bearing products as a way of promoting university identity, specifically, the effects of ingroup ties, ingroup affect, and centrality on attitude toward university logo products and purchase intention. This study further examined the moderating effects of perceived university prestige on the relationship between logo product attitude and in-store purchase intention, and the moderating effect of online shopping frequency on the relationship between logo product attitude and online purchase intention. We conducted a survey of undergraduate and graduate students at a university in Seoul. Survey responses (N=561) were collected and processed using SPSS 23.0. Multiple regression analysis showed that ingroup ties and affect had significant effects on product attitude. However, centrality had no significant effect on attitude toward the product. Product attitude had a direct significant effect on both in-store and online purchase intention. Perceived university prestige moderated the relationship between product attitude and in-store purchase intention. Moreover, online shopping frequency moderated the relationship between product attitude and online purchase intention. The results of this study are expected to provide fundamental knowledge for developing product strategy of logo products.

Background: Since the mid-20th century, the ways in which social networks and older adults' health are related have been widely studied. However, few studies investigate the relationship between self-rated health and position in a complete social network of one entire Korean rural village. This study highlights use of a complete network in health studies. Methods: Using the Korean Social Life and Health Project, the population-based data of adults aged 60 or older and their spouses in one myeon in Ganghwa island (Ganghwa-gun, Incheon, Korea), Incheon, Korea (with a 95% response rate), this study built a $1,012{\times}1,012$ complete social network matrix of the village. The data were collected from 2011 to 2012, and 731 older adults were analyzed. The ordered logistic models to predict self-rated health allowed us to examine social factors from socio-demographic to individual community activities, ego-centered network characteristics, and positions in a complete network. Results: From the network data, 5 network components were identified. Even after controlling for all other factors, if a respondent belonged to a segregated component, the probability that he or she reported good health dropped substantially. Additionally, high in-degree centrality was connected to greater self-rated health. Conclusion: This finding highlights the importance of social position not only from the respondents' point of view but also from the entire village's perspective. Even if a respondent maintained a large social network, when all of those social ties belonged to a segregated group in the village, the respondent's health suffered from this segregation.

Objectives : This study was conducted to examine social factors associated with problematic drinking among middle- and older-aged men in South Korea. Methods : The data were collected from the baseline survey of the Korean Longitudinal Study of Aging, and the sample consisted of 3,631 men between 45 and 64 years of age and 1,173 men aged 65 or older. This study employed variables identifying various socioeconomic features, social ties, and health-related factors. Logistic regressions were used for the data analysis. Results : Middle-aged men having frequent social relationship with close persons were significantly more likely to be problematic drinkers than those having less frequent social relationships with close persons. Lower education, unemployment, smoking, and depression were associated with problematic drinking only among middle-aged men. Conclusions : We suggest that health professionals develop specific intervention strategies that could lead to more moderate alcohol habits and better health in middle aged Korean men who are actively engaged in social networks. In addition, health professionals need to focus more on the unemployed, lower educated, depressed, and smoking groups for early detection of problematic drinking among middle-aged Korean men.

The purpose of marketing via Facebook is to convince consumers to become fans of a brand. Facebook constructs virtual brand communities that enable brand fans to interact with these brands. This study investigates the antecedents and consequences of fan participation characterized by the breadth and depth of brand fans' like, comment, and share activities. An empirical analysis with 204 survey respondents reveals that expected benefits, such as brand information, social interaction ties, playfulness, and incentive, have positive effects on fan participation. Furthermore, fan participation increases fan's attitudinal loyalty, which then positively affects behavioral loyalty. Theoretical and practical implications of the findings as well as future research directions are also discussed.

This study aimed to identify orientations for the development of the community by establishing desirable aesthetical environments and reorganizing the residents' communal way of life through the implementation of village art projects. To investigate how the implementation of village art projects influence community and communication, the author analyzed changes in walls made by the implementation of actual projects in Anhyeon Village in Gochang, Dongpirang in Tongyeong, and Byeolbyeol Village in Yeongcheon. The community was analyzed from the view points of locality, communal ties, and communication. The results showed that Anhyeon Village in Gochang expressed its locality with chrysanthemum, poems and local figures. Similar walls were built across the village to strengthen ties among the residents, and portraits used as doorplates represented communication among them. Various paintings of seas, flowers, and poems were seen in Dongpirang in Tongyeong, which were thought to be representations of its locality and the friendliness of hometown in the less favoured area. Wall paintings played pivotal roles in this village to impart to the residents essentials that should be kept to eliminate inner walls in their minds and ensure open communications. In Byeolbyeol Village in Yeongcheon, locality was presented with common farm village landscapes in various materials, patterns and formativeness. Village-wide reinforcement contributed to strengthening ties in the community rather than forming boundaries against outside worlds. Cultural and artistic elements structured mental walls that made people not aware of the presence of physical walls.

With rapid growth of content demands, device-to-device (D2D) content sharing is exploited to effectively improve the service quality of users. Considering the limited storage space and various content demands of users, caching schemes are significant. However, most of them ignore the influence of the asynchronous content reuse and the selfishness of users. In this work, the user preferences are defined by exploiting the user-oriented content popularity and the current caching situation, and further, we propose the social-aware rate, which comprehensively reflects the achievable contents download rate affected by the social ties, the caching indicators, and the user preferences. Guided by this, we model the collaborative caching problem by making a trade-off between the redundancy of caching contents and the cache hit ratio, with the goal of maximizing the sum of social-aware rate over the constraint of limited storage space. Due to its intractability, it is computationally reduced to the maximization of a monotone submodular function, subject to a matroid constraint. Subsequently, two social-aware collaborative caching algorithms are designed by leveraging the standard and continuous greedy algorithms respectively, which are proved to achieve different approximation ratios in unequal polynomial-time. We present the simulation results to illustrate the performance of our schemes.

This study was conducted to identify the attributes constituiting Korean social support and to validate the results of the previous study ‘Search for the meaning of social support in Korean Society.’ The informants were 41 Korean middle-aged women in three cities Seoul, Daejun and Daeku. The data were collected through indepth interviews using the interview guide from Jun. 1994 to Jun. 1995. The interview guide was developed in the simulated situations of ‘Stroke attack’ which expected to be in need of social support. The women were asked to answer what they felt and the appropriate terms representing the situations. Data analysis were conducted by content analysis. Consequently, the Korean social support pyramid was modified as follows ; Support is the apex of the pyramid. The four sides of the pyramid are made up of ‘Jung’(Bound by ties of affection, regard or shared common experience, Connectedness), Do-oom(both emotional and material help), Mi-dum(Faith or belief in) and Sa-Rang(Love). The base of the pyramid is ‘yun’(the basic network of relationships in Korean culture) that connote the meaning of Eunhae(Benevolence), Euimu(duty, responsibility) and Dori(obligation).

Online social networks(OSN) are very popular nowadays. As OSNs grows, the commercial markets are expanding their social commerce by applying Influence Maximization. However, in reality, there exist more than two players(e.g., commercial companies or service providers) in this same market sector. To address the Influence Maximization problem between adversaries, we first introduced Influence Maximization against the social adversaries' problem. Then, we proposed an algorithm that could efficiently solve the problem efficiently by utilizing social network properties such as Betweenness Centrality, Clustering Coefficient, Local Bridge and Ties and Triadic Closure. Moreover, our algorithm performed orders of magnitudes better than the existing Greedy hill climbing algorithm.
