We in this paper propose a social network based on ontology in Korea Institute of Oriental Medicine (KIOM). By using the social network, researchers can find collaborators and share research results with others. For this purpose, first, personal profiles, scholarships, careers, licenses, academic activities, research results, and personal connections for all of researchers in KIOM are collected. After relationship and hierarchy among ontology classes and attributes of classes are defined through analyzing the collected information, a social network ontology are constructed using FOAF and OWL. This ontology can be easily interconnected with other social network by FOAF and provide the reasoning based on OWL ontology.

Background: The purpose of this study was to examine the cohesions status of the coordination within response teams in the emergency response team (ERT) in a refinery. Methods: For this study, cohesion indicators of social network analysis (SNA; density, degree centrality, reciprocity, and transitivity) were utilized to examine the coordination of the response teams as a whole network. The ERT of this research, which was a case study, included seven teams consisting of 152 members. The required data were collected through structured interviews and were analyzed using the UCINET 6.0 Social Network Analysis Program. Results: The results reported a relatively low number of triple connections, poor coordination with key members, and a high level of mutual relations in the network with low density, all implying that there were low cohesions of coordination in the ERT. Conclusion: The results showed that SNA provided a quantitative and logical approach for the examination of the coordination status among response teams and it also provided a main opportunity for managers and planners to have a clear understanding of the presented status. The research concluded that fundamental efforts were needed to improve the presented situations.

Due to the recent expansion of the Web 2.0 -based services, along with the widespread of smartphones, online social network services are being popularized among users. Online social network services are the online community services which enable users to communicate each other, share information and expand human relationships. In the social network services, each relation between users is represented by a graph consisting of nodes and links. As the users of online social network services are increasing rapidly, the SNS are actively utilized in enterprise marketing, analysis of social phenomenon and so on. Social Network Analysis (SNA) is the systematic way to analyze social relationships among the members of the social network using the network theory. In general social network theory consists of nodes and arcs, and it is often depicted in a social network diagram. In a social network diagram, nodes represent individual actors within the network and arcs represent relationships between the nodes. With SNA, we can measure relationships among the people such as degree of intimacy, intensity of connection and classification of the groups. Ever since Social Networking Services (SNS) have drawn increasing attention from millions of users, numerous researches have made to analyze their user relationships and messages. There are typical representative SNA methods: degree centrality, betweenness centrality and closeness centrality. In the degree of centrality analysis, the shortest path between nodes is not considered. However, it is used as a crucial factor in betweenness centrality, closeness centrality and other SNA methods. In previous researches in SNA, the computation time was not too expensive since the size of social network was small. Unfortunately, most SNA methods require significant time to process relevant data, and it makes difficult to apply the ever increasing SNS data in social network studies. For instance, if the number of nodes in online social network is n, the maximum number of link in social network is n(n-1)/2. It means that it is too expensive to analyze the social network, for example, if the number of nodes is 10,000 the number of links is 49,995,000. Therefore, we propose a heuristic-based method for finding the shortest path among users in the SNS user graph. Through the shortest path finding method, we will show how efficient our proposed approach may be by conducting betweenness centrality analysis and closeness centrality analysis, both of which are widely used in social network studies. Moreover, we devised an enhanced method with addition of best-first-search method and preprocessing step for the reduction of computation time and rapid search of the shortest paths in a huge size of online social network. Best-first-search method finds the shortest path heuristically, which generalizes human experiences. As large number of links is shared by only a few nodes in online social networks, most nods have relatively few connections. As a result, a node with multiple connections functions as a hub node. When searching for a particular node, looking for users with numerous links instead of searching all users indiscriminately has a better chance of finding the desired node more quickly. In this paper, we employ the degree of user node vn as heuristic evaluation function in a graph G = (N, E), where N is a set of vertices, and E is a set of links between two different nodes. As the heuristic evaluation function is used, the worst case could happen when the target node is situated in the bottom of skewed tree. In order to remove such a target node, the preprocessing step is conducted. Next, we find the shortest path between two nodes in social network efficiently and then analyze the social network. For the verification of the proposed method, we crawled 160,000 people from online and then constructed social network. Then we compared with previous methods, which are best-first-search and breath-first-search, in time for searching and analyzing. The suggested method takes 240 seconds to search nodes where breath-first-search based method takes 1,781 seconds (7.4 times faster). Moreover, for social network analysis, the suggested method is 6.8 times and 1.8 times faster than betweenness centrality analysis and closeness centrality analysis, respectively. The proposed method in this paper shows the possibility to analyze a large size of social network with the better performance in time. As a result, our method would improve the efficiency of social network analysis, making it particularly useful in studying social trends or phenomena.

Based on the theoretical review of social cooperatives and the results of the fourth round of fact-finding, this study tried to discuss the sustainability of social co-operatives from the social, economic, and environmental aspects, focusing on the seven principles of co-operatives. The issue of sustainability is "a development that meets the needs of the present without compromising the ability of future generations to meet their own needs, the use of resources, the direction of investment, technological advances and institutional change in harmony with one another. as defined as "a process of change that advances the needs and desires of all future generations". It contains the meaning of connecting a sustainable society to future generations through harmony and balance, rather than opposing concepts of social value, environmental conservation, and economic growth. As a result of arranging the concept of social, economic, and environmental sustainability contained in sustainable development, and the seven principles of cooperatives and their connections, I would like to suggest the following about the sustainability of social cooperatives. First, efforts should be made for social contribution closely related to the local community. Second, it is necessary to create a profit model along with the public interest. Third, partnerships should be strengthened. When examining the public values and objectives that social cooperatives want to realize through this study, the three scopes of sustainable development are directly related to the role of important actors in pursuing social and economic values that social and economic organizations are facing. would. Therefore, the sustainability issue of social cooperatives is based on the concept that the goals and values pursued by social cooperatives are harmonious and balanced development in the environmental, social, and economic aspects, not only their own efforts but also the institutional support of the government. this will have to be presented.

Research regarding corporate associations in marketing has generally been approached using the association theory. However, limited research investigates the effect of corporate associations on consumer loyalty to individual brands by examining the role of self connectedness with a corporate image. The activation of behavior-related constructs can influence individuals' behaviors without their intention or conscious awareness. A recently developed body of research suggests that self connection can play an important role in affecting subsequent behaviors. Although these effects have received considerable attention, the set of mechanisms involved in self connectedness and loyalty to individual brands is not clear. An active self account in which associative constructs can affect behavior by temporarily altering the active self-concept may lead to behavior or evaluation. If the exposure to a corporate brand can induce consumers' cognitive associations and goal-primed effects through the role of active self accounting, the connectedness between the consumer's self and the corporate brand could be developed and this connectedness could be explained by associative and connection models and the goal priming theory. Therefore, this study investigates the influence of corporate associations on loyalty to individual brands through connections between the corporate and the consumer's self. There are three main purposes of the research. First, theories regarding corporate associations will be explored. Second, theories of self-concept will be investigated and self connectedness with corporate brands will be explored. Third, the effects of the connectedness between the self and the corporation on corporate identification and loyalty to individual brands will be investigated. For the purposes of this research, the types of corporate associations are classified into corporate ability (CA) associations and corporate social responsibility (CSR) associations. Furthermore, the connectedness between the consumer's self and the corporate image are divided into two concepts: the connectedness between the individual self-concept and the corporate identity and the connectedness between social self-concept and the corporate identity. This study suggests the hypotheses that the types of consumer self connections with the corporate image could vary according to the types of corporate associations created and further that the connectedness between the corporate association and the consumer's self-concept have positive effects on loyalty to corporate individual brands. The results of testing these hypotheses are as follows. First, corporate ability associations enhance the connectedness between the consumer's individual self and corporate brands. That is, corporate ability associations influence individual connectedness between the corporate and individual self-concept positively from the viewpoint of the consumer's personal ability and branding success. In addition, corporate social responsibility associations have a positive effect on social connectedness between the corporation and the consumer's social self-concept. Second, the connectedness between the corporate brand and the consumer's self-concept affects identification with the corporation. The consumer's personal self and social self connectedness induces corporate identification. Third, individual self connectedness has a positive effect on loyalty to corporate individual brands, while social self connectedness does not. This also means that individual self connectedness with the corporate image or brand plays a more important role in forming individual brand loyalty than social self connectedness with the corporate does. In addition, social connectedness cannot influence individual brand loyalty until it passes through identification with the corporate. Fourth, consumers who experience identification with a corporate identity also show positive responses to corporate individual brands. That is, consumers also develop loyalties toward individual brands through the corporate identification because self-pursued goals that are induced by corporate associations can be achieved by consuming the individual brands that are sold by the corporate that the consumers identify with.

The purpose of this study was to examine the impact of the social maturity of sustained sport-for-all participants on their physical and mental health. The subjects in this study were 190 company employees who were selected by convenience sampling from among the residents in Gangwon Province. The selected office workers continued to participate in sport-for-all programs. After a survey was conduced from November 7 to 25, 2011, the statistical package SPSS WIN 18.0 was employed to analyze the collected data. To find out the general characteristics of the subjects, frequency analysis was made, and the reliability test of the instrument and factor analysis were carried out. Descriptive statistics analysis was made by factor, and multiple regression analysis was utilized to look for connections among their variables. As a result, it's found that the social maturity of the sustained sport-for-all participants made a significant difference to their physical health, and that their social maturity made a significant difference to mental health as well. As sustained sport-for-all participation was found to be correlated to their physical and mental health, office workers should be given a chance to participate in sport-for-all on a long-term basis.

This study aims to investigate the factors on help-seeking behaviors among the disabled experiencing lifelong domestic violence and suggest practical plans to address the problems. According to an analysis of the data of the "2010 Domestic Violence Survey of South Korea", the occurrence rate of lifelong physical violence is 12.1% and that of severe physical violence is 6.2% among 273 adults with disabilities. The rate of help-seeking among the disabled experiencing lifelong domestic violence is 26.3%, which means two-thirds of the disabled experiencing domestic violence do so for a long time. The results of the study show that the experience of severe physical violence(p<.05), attitudes toward violence(p<.05), and awareness of domestic violence and related laws(p<.05) were found to have an impact on help-seeking behaviors among adults with disabilities experiencing domestic violence. However, an accepting attitude of disability and social connections of disabled were not found to have an impact on help-seeking behaviors. Based on these results, this study suggested raising awareness about domestic violence among the disabled, educating people with disabilities not to tolerate violence and informing them about the domestic violence-related legal system, and training service professionals (social workers, health professionals etc.) to screen the disabled for domestic violence and prevent them from becoming domestic violence victims.

I had an interview with some unemployed career staffs who had retired and worked for more than twenty years in order to research impacting elements on reemployment for l retired special security government officials. This interview included an officer and a consultant for supporting employment in order to explore compacting elements on retired security government official's reemployment. Looking over analysis results, first, there is a shortage of reemployment opportunities and information. The job applicant's employment requirements are not in accordance with the company's employment conditions. They don't have enough professional experience necessary for employment. There is no positive employment supporting counterplan or vocational education program in the organization. Second, their insight about finding a job is high for the current employment market condition. The reemployment offices have a very difficult task because job applicants prefer a full-time job which offers long term work and guarantees a social position. Third, it is a huge obstacle to undertake going into various enterprises and fields because they don't have the right mind set and enough preparation for reemployment. Moreover, they would prefer to depend on organization employment support rather than getting a new job by themselves when they don't possess other careers' qualifications. Finally, they know that social networks and personal connections are extremely important in obtaining vocations, but actually have poor social networks and few personal connections. Accordingly, Their organization and related persons need to reflect on analysis results about impacting elements on reemployment for retired special security government officials.

Competitiveness of container ports has been traditionally evaluated by capability of individual ports to provide services to customers or their service quality. However, since container ports are connected by container shipping networks to varying degrees, the status of the ports in liner shipping service networks also determines competitiveness of the ports. Sometimes same ports may play different roles in different forms of shipping networks. Shipping network connections that formulate in container ports therefore have more significant impact on their performance than service capabilities they have. This study aims to explore how the shipping and port network has been structured and changed in the past and to examine the network characteristics of ports using Social Network Analysis(SNA). In this SNA study, nodes in the network are the ports-of-call of the liner shipping services and links in the network are connections realized by vessel movements, such that the liner shipping networks determine the port networks. This study, therefore, investigates the liner shipping networks and through its results demonstrates the network characteristics of the ports that are represented by the four centrality indices. This provides port authorities and terminal operating companies with managerial implications to enhance competitiveness from customers' perspectives.

Purpose - In this research, we investigate the relationship between the level of information technology utilization, social capital and knowledge management, organization performance. For information and knowledge management, participants' certain level of information technology utilization is required and connections among participants are necessary for performing and for synergy effects. Research design, data, and methodology - Reflecting on these, we empirically analyze the effects of participant's information technology utilization level and social capital on knowledge management and organization achievement for the case of Incheon International Airport. Questionnaire is distributed to the airport employees and collected 221 samples for analyzing. SPSS and AMOS statistic programs are used for analysis. Factor analysis, Credibility adaptability, path analysis, hypotheses are verified. Results - The study research shows as follow. First, the level of IT utilization does affect social capital but does not affect knowledge management. Second, social capital affects both knowledge management and organization achievement. To investigate more about the relationship between the level of IT utilization and knowledge management, we analyzed the control effects of personal characteristics, and findings are, first, employees with longer time service recognize the importance that the level of IT use and knowledge management affect organization achievement more seriously than employees with shorter time service do. Second, employees with shorter time service and younger employees have relatively lesser social capital and participate in knowledge management passively. Third, higher position employees think that the level of IT utilization affects knowledge management while lower position employees do not. Conclusions - The level of IT utilization affects social capital, and social capital affects knowledge management and organization achievement. These results suggest that the level of IT utilization is very important to both organization and each employee. So providing related training and education opportunities or incentives to induce employees to make efforts for higher level of IT utilization and thus to participate in knowledge management more actively is necessary. The level of IT utilization affects social capital which airport employees lack. The one of study results indicates the importance of social capital and for higher competitiveness of the airport social capital should be increased.
