This study was carried out as a preliminary study to analyze how emotion(depression and anxiety) after spouse bereavement in old age affects social interaction and to set a direction of developing programs based on the cause and period of bereavement to promote social interaction for those bereaved people. To that end, welfare facilities and schools for the elderly and churches located in Seoul, and Suwon and Osan areas were visited and surveys were executed on 350 aged people who had experienced spouse bereavement from September 26 through October 25, 2014. Analysis was executed for 325 questionnaires out of the total of 350 using SPSS WIN 20. Study findings are as follows: first, the average of emotion and social interaction due to bereavement was not significantly different between groups; second, the average of emotion and social interaction due to bereavement period was not significantly different between groups; third, the impact of bereavement type and period statistically significant. These findings implies that social interaction programs for the aged people can be developed regardless of bereavement cause or period.

The purpose of this study is to analyze the cause-and-effect relationships among positive verbal expressions from family members, social network, and disability identity as the determinant factors of intention to work. To achieve the goal, 453 persons with disabilities and with experiences of using facilities for the disabled were studied, who were recruited for the national survey of domestic violence in 2010. For the research subjects, the cause-and-effect relationships among the major factors were examined by using a structural equation model. According to the results, disability identity and intent to work tended to be higher as they had experienced more of positive verbal expressions from their families. Moreover, a more participation in social activities increased disability identity, but not intent to work. Lastly, disability identity was found to be a determinant of intent to work. Based on the results, we provide suggestions to achieve social inclusion of people with disabilities by raising the intent to work.

Cooperative spectrum sensing has been considered as a promising approach to improve the sensing performance in distributed cognitive radio networks. However, there may exist some selfish secondary users (SUs) who are unwilling to cooperate. The presence of selfish SUs could cause catastrophic damage to the performance of cooperative spectrum sensing. Following the social perspective, we propose a Social Tie-based Incentive Scheme (STIS) to deal with the selfish problem for cooperative spectrum sensing in distributed cognitive radio networks. This scheme inspires SUs to contribute sensing information for the SUs who have social tie but not others, and such willingness varies with the strength of social tie value. The evaluation of each SU's social tie derives from its contribution for others. Finally, simulation results validate the effectiveness of the proposed scheme.

The purpose of this study was first, to examine the causes for the recent acceleration in the increase of textile/apparel waste and the current practices for reducing waste in the global textile and apparel industry; and second, to explore the influence of sustainability and social responsibility on fashion trends. Extensive literature on sustainable apparel and sustainable and socially responsible practices by global textile and apparel firms was reviewed in conducting this research. First, an accelerated fashion diffosion speed due to fast fashion was focused on as a cause for the increase in textile/apparel waste whereas mass customization was focused on as a potential solution for reducing waste. Then, the influence of the social trend toward sustainability and social responsibility on fashion trends was discussed, particularly the trends toward green products and recycled fashion, the trend against using real for or leather, and minimum-fabric-waste fashion in design and product development. This study furthers consumers' understanding of sustainability and social responsibility related to fashion trends and hopefully increases their consciousness in becoming socially responsible consumers. This study will also contribute to better decision-making in apparel and textile firms to produce sustainable fashion products.

This paper deals with the social system from the point of system thinking consisting the fundamental construct of system dynamics. The Bertalanffy's general system theory, having been criticized because of its ambiguity, and the complex science theory, emerging system theory, are integrated by using the system thinking which is characterized with three concepts, 'feedback thinking', 'dynamic thinking', 'operational thinking'. In the integration, system thinking suggests the dynamic pattern of the social system have not only an equilibrium status but also complex status. The science of complexity gives an implication to system dynamics the important of the uncertainty and complexity if we interpret the social system as an open system. To show more concrete description, I simulate the cooperation model based on the iterated prisoner dilemma. The simulation results show the diverse patterns of cooperation and betrayal. Especially the sensitivity of initial payoff will cause the chaotic strategic landscapes as the game gose on. These results mean that we should not give the hasty prescription to control social system artificially. Because social system retains the self-organizing force in itself.

The rapid development and widespread application of Internet has provided a platform for people to participate and discuss social hotspot events. In the meantime, social events may be spread throughout the Internet more quickly and widely than they did ever before, and possibly lead to serious social problems due to opinion violence or seditious rumour. This paper analyzed the Internet spread of social events, and presented a five-stage model to describe the evolution process of that spread. Furthermore, the improved IBF algorithm was applied to extract a pruned connected graph aiming to find the key nodes and the shortest spread path for the control of that spread. After analyzing the different factors that may cause the netizens' attention, this paper concluded BBS type, the visit quantity and the opinion leader are key factors which affect the Internet spread. Based on those researches, a life-cycle emergency management methodology and the related strategies were proposed for the achievement of healthy spreading environment on Internet.

The present paper study investigates the relationship between social exclusion and donation intention among specific social groups in Korea. Social exclusion refers to non-participation in social experiences by the socially disadvantaged. Data were analyzed using two sources; first was the evidence of behaviors arising from social exclusion of the university students and then socially excluded reactions of the elderly responses from the survey were compared with the first research findings. The reason of using multi-sources of data is that the outcome from the experimental design of the university student is imperative to clarify what the conclusions will be the same result with the other demographic characteristic of the elderly. The research design was three excluded elderly individuals of a self-excluded group and two other excluded groups divided such as "ignored" and "rejected" individuals to compare the differences among three groups of different sources of exclusion. The conclusion of this study is that those with high social exclusion exhibited a more negative donation intention than those with lower social exclusion, but that those who perceived themselves as self-excluded were more likely to give donations than those excluded by others, regardless of the level of their social exclusion.

This study aims to examine the effects of message framing of restaurant menus on customers' perceptions (trust and immersion) and their willingness to pay a premium price. The contents of messages focused on a hypothetical restaurant's cause-marketing activity. Four types of message framing were created: The first two types were varied by the presence and absence of the information about the current cause-marketing outcome, and the second two types were varied by positive and negative framing. The results showed that respondents in general had trust in cause-marketing messages and immersion of cause-marketing message by negative framing lead to positive influence of willingness to pay. Furthermore it had a significant effect on willingness to pay depending on cause-marketing message type and negative message framed messages showed an intention to willingness to pay a premium price. This study compared the difference in messages by type as an extension of the studies of cause-marketing messages in the past. The results of this study will be used for establishing effective marketing strategies for today's foodservice companies and serve as objective data for setting differentiated prices under the circumstance where the importance of companies' social responsibilities is growing.

This study was carried out to verify how much instructor's communication skill affects the student pilot's study motivation and satisfaction. The instructor's communication styles are classified into 3 groups by pre-analysis. Three types are cooperative type, control type and professional type. Intellectual cause, performance proficiency cause, social cause and stimulation avoidance cause are extracted and analyzed for the cause of study motivation. Cooperative and control type affected all of 4 factors of student's study motivation by influence analysis. Intellectual cause affected control and cooperative type positively, especially more to cooperative type. Performance proficiency cause also had positive influence to control and cooperative type. Stimulation avoidance cause didn't appear to affect all sub-classified 4 factors of instructor's communication type. Influence analysis of student's study satisfaction from instructor's communication style showed that independent variable affected all sub factors positively. Degree of positive influence affected the control type the most, cooperative type was the 2nd, and professional type was the 3rd.

This study analyzes the social function of democracy and the essential problems of social security of democracy. So far democracy has used a political term in politics. Democracy allows us the right to the freedom of individuality and social equality. Even scholars however, neglect to study about the criticism of democracy and social problems that are caused by democracy. It was expected that democracy would be valued by humans throughout the world. People have been fighting to establish a reliable political system of democracy. So they can have security in their society and the subject of politics. Therefore, We should consider study on democracy in function of democracy in relation to security of society and essential problems on what is democracy? Does democracy change with social change? Didier Bigo said, 'rising of freedom cause rising of a social unrest', B. Jeanneau said 'Democracy itself is the starting of social discord'. These are criticism of social security, the system and the function of democracy. It especially explains social discord and unrest that has occurred by an authoritative interpretation of democracy or the meaning of a word interpretation. It is a question of the day that it's converse the function of the system and the operation of democracy, act as social unrest.
