  • Despite various types of online social networks having different topological and functional characteristics, the kinds of online social networks considered in social recommendations are highly restricted. The pervasiveness of social networks has brought scholarly attention to expanding the scope of social recommendations into more diverse and less explored types of online social networks. As a preliminary attempt, this study examined the information-sharing patterns of a new type of online social network - unilateral (directed) network - and assessed the feasibility of the network as a useful information source. Specifically, this study mainly focused on the presence of shared interests in unilateral networks, because the shared information is the inevitable condition for utilizing the networks as a feasible source of personalized recommendations. As the results, we discovered that user pairs with direct and distant links shared significantly more similar information than the other non-connected pairs. Individual users' social properties were also significantly correlated with the degree of their information similarity with social connections. We also found the substitutability of online social networks for the top cohorts anonymously chosen by the collaborative filtering algorithm.

  • This study analyzes the relationships between social networks and loneliness. Subjects of this study are male and female undergraduate students residing in Soul and Jeonju city Questionaires were and the obtained results were analyzed through SPSS PC+ The results are as follows 1) The size of general social networks doesnt's show difference between male and female students but at the of intimate social networks female students' one is bigger than male students' And female students' contact frequency via telephone is higher than male students' but the direct contact frequency did not show the difference: 2) The bigger the size of social networks is and the higher the contack frequency is the more the mount of social supports female students get. And the bigger the size of social networks is the more the amount of social support male students get. But among male students there are no relationships between the contact frequency and the amount of social supports 3) The size and co tact frequency of social networks is negatively related to loneliness among female and male students 4) The amount of social supports explaines the degree of loneliness at 23% among female students and 18% among male students.

  • Purpose: The purpose of this study was to investigate the relationships of social networks to health status among the urban low income elderly. Method: Using a sample of 598 elderly aged 65 years and higher, social networks, health status were measured by the Social Networks Scale (LSNS), Perceived Health Status, GDSSF-K, K-ADL respectively. The t-test, ANOVA and Tukey-test and Pearson's correlation analyses were performed using SPSS 18.0. Results: 41% of subjects didn't contact with relatives at least once a month. 56% of subjects saw or heard less than monthly from relative with whom they have the most contact. 47% didn't have relatives who one can rely on private matters. Social networks among the low income elderly significantly differed by marital status, health insurance type, economic status, regular exercise, living with family. Social networks were significantly correlated with perceived health status (r=.201), cognitive function (r=-.154) and depressive symptoms (r=-.301). Conclusion: Poor social networks were found in urban low income elderly. Poorer social networks were related to worse health status and more depressive symptoms. Interventions targeting at increasing social networks are urgently needed for low income elderly.

  • Unstructured peer-to-peer (p2p) networks usually employ flooding search algorithms to locate resources. However, these algorithms often require a large storage overhead or generate massive network traffic. To address this issue, previous researchers explored the possibility of building efficient p2p networks by clustering peers into communities based on their social relationships, creating social-like p2p networks. This study proposes a social relationship p2p network that uses a measure based on Hebbian theory to create a social relation weight. The contribution of the study is twofold. First, using the social relation weight, the query peer stores and searches for the appropriate response peers in social-like p2p networks. Second, this study designs a novel knowledge index mechanism that dynamically adapts social relationship p2p networks. The results show that the proposed social relationship p2p network improves search performance significantly, compared with existing approaches.

  • The purpose of this study was to investigate the characteristics of the social networks and its relationship with the psychological well-being of middle-aged men. The participants were 314 men who were married living in Pusan, aged between 40 and 59, having occupation and children. Data were collected by questionnaire which consists of Social Networks Scale and Psychological Well-being Scale. The major results of the study were summarized as follows; First, the range of the social contact with men's own kin was wider than women's. In the contact frequency of midge-aged men, primary networks were shown more frequent contact than the secondary networks. In the characteristics of interactive function of social networks, kinship of the middle- aged men, their partners and friendship networks were the most important among the six networks, which agrees the fact that kin are still the primary source of social support. Second, the level of psychological well-being was lower than family-related satisfaction and work-related satisfaction. In the work-related satisfaction, the level of job satisfaction was lower than the other sub-categories. Psychological well-being of middle-aged men were affected by Social economic status as well.

  • This study was conducted to explore the relationships between the social networks formed by insurance planners and their job competence and performances such as their insurance records and satisfaction. To that end, first, the effects of social networks held by insurance planners on their job competence for actual insurance sales were reviewed. Second, the effects of the social networks on the insurance planners' insurance solicitation records and satisfaction were examined. Third, the influential relationships between insurance planners' job competence and performance were reviewed. For this study, insurance planners working in life insurance companies, fire and marine insurance companies, and general agencies(GA) were selected as the subjects of this study to conduct questionnaires surveys and derive study results. Through the analyses, although some variables were rejected, overall results indicating that social networks affect insurance planners' job competence to improve their performance were obtained. These study results can be said to support the argument of the network theory that social networks improve entrepreneurs' performance. The elements of job competence that had effects on insurance planners' performance were self-efficacy, achievement orientation, and customer orientation, and these three elements of job competence were affected by three components of social networks; the relational dimension, cognitive dimension, and structural dimension of social networks. Therefore, the results of this study indicate that insurance planners can improve their actual insurance solicitation performance as well as their job satisfaction by sharing visions among network members based on trust.

  • This study aimed to explore the social networks which married immigrant women have in Korea. Special attention was paid to factors such as individual, family, and migrant characteristics contributing to the different patterns of social networks. I drew upon the nationally representative data on 60,719 immigrant women married to Korean men from the '2009 Survey on Korean National Survey on Multicultural Families.' Results showed that the foreign wives tended to maintain a connection with our society through contact with their neighbors and participation in social gatherings. Findings also showed that the types of social networks by the number of trusted neighbors and meetings were diverse among the immigrant women. In addition, the factors differentiating the types were mostly associated with socioeconomic resources or Korean proficiency. More interestingly, the immigrant women's contacts with their family members in their homeland contributed to their maintenance of more active social networks. These results provided a useful outlook on the relationship between patterns of social networks and the characteristics of the married immigrant women, which eventually showed a heterogeneous nature among them. At the societal level, supportive systems for enriching immigrant women's social networks should be developed particularly in terms of not their dependency, but their potential contributions to our society.

  • This study investigated how different relationships the family has with its social networks by social class. Among research families' primary social networks, the wife's relatives are the most, the neighbor the second, the husband's relative the third, and the church (or other religious groups) the fourth. Social class does not make any difference in what social network is the family's primary social network. When the husband or the wife participates in a social network, he or she tends to participate alone without his or her spouse. When the husband's educational level is high, the wife tends to participate in her alumni association alone. When the husband is in a professional or a white-collar occupation, he is likely to socialize with his work associates alone. On the contrary, when the family income gets high, the husband tends to bring his wife to his alumni association. When looking for a job, most husbands and wives do not resort to a social network for help. Lower-class people are more likely to obtain jobs through their social networks compared to higher-class people. That is, the lower one's educational levle, one's occupational status, or the family income is, the more likely one gets help from some social networks in searching jobs.

  • Online social network technologies have become important to health and apply in most health care areas. Particularly in cancer care, because it is a disease which involves many social aspects, online social networks can be very useful. Use of online social networks provides a suitable platform for cancer patients and families to present and share information about their medical conditions, address their educational needs, support decision making, and help to coping with their disease and improve their own outcomes. Like any other new technologies, online social networks, along with many benefits, have some negative effects such as violation of privacy and publication of incorrect information. However, if these effects are managed properly, they can empower patients to manage cancer through changing behavioral patterns and enhancing the quality of cancer patients lives This paper explains some application of online social networks in the cancer patient care process. It also covers advantages and disadvantages of related technologies.

  • Purpose: The principal objective of this study was to assess correlations among the self-efficacy, social support networks, and health behavior of undergraduate students. Methods: The data were collected via questionnaires that investigated self- efficacy, social support networks, health behaviors, health-related factors, and general characteristics. A total of 310 subjects were selected and evaluated for a 3-week period. The data of 300 subjects were analyzed using descriptive analysis, t-test, ANOVA, and correlation, after 10 questionnaires had been excluded due to incomplete data. Results: We noted significant differences and impacts on self-efficacy according to the grade, perceived health status, and BMI. Social support networks differed significantly according to dwelling type and pocket money. Health behavior differed depending on the gender, major, dwelling type, religion, health status, and BMI. We noted a significant positive correlation between self-efficacy & social support networks, and between social support networks & health behavior, but we noted no significant correlation between self-efficacy & health behavior. Conclusion: Health care providers should focus on self-efficacy and social support networks in order to prevent bad health behavior among undergraduates.
