This paper aims to provide a general review of Opinion Dynamics (OD) and its related models, along with application examples for special agents. We will discuss special classes of social actors, such as informed actors, opponents, and extremists, in the context of opinion dynamics. Our main objective is to determine the extent to which opinion dynamics, as a mathematical sociology, relates to social reality. To achieve this, we present key elements of mathematical sociology in Opinion Dynamics, which we then apply to real socioeconomic phenomena using modeling assumptions and mathematical formulations.

Child labor is being recognized as the key issue of human rights, and the International Labor Organization and the Convention on the Rights of the Child emphasize that children are individuals with dignity and rights. Male and female child actors belong to a profession with wide public exposure and there is a potential danger of invading classes and roles not matching the developmental stage of the child. In this study, we would like to discuss international and domestic laws and future complementary measures surrounding legal and institutional issues that need to be considered for child actors. Although the basic rights for child workers are stated in the Constitution Article 32 Paragraph 5 and Labor Standards Act Articles 64 through 70, they are insufficient. Following the revised broadcasting deliberation regulations by the Korea Communication Commission and amendment of the Juvenile Protection Law, several changes are taking place in the working environment. In certain foreign places such as California, United States, the economic and educational rights of male and female child actors are being protected. Although legal and institutional frameworks for the male and female child actors are being reinforced, more consistent devices are needed. Consideration for working hours, regulations to keep up with learning while working, and preparation for physical and emotional influences are required to keep up with international changes.

Objectives: To assess the current public participation in-local health policy and its implications through the analysis of policy networks in health center programs. Methods: We examined the decision-making process in sub-health center installations and the implementation process in metabolic syndrome management program cases in two districts ('gu's) of Seoul. Participants of the policy network were selected by the snowballing method and completed self-administered questionnaires. Actors, the interactions among actors, and the characteristics of the network were analyzed by Netminer. Results: The results showed that the public is not yet actively participating in the local public health policy processes of decision-making and implementation. In the decision-making process, most of the network actors were in the public sector, while the private sector was a minor actor and participated in only a limited number of issues after the major decisions were made. In the implementation process, the program was led by the health center, while other actors participated passively. Conclusions: Public participation in Korean public health policy is not yet well activated. Preliminary discussions with various stakeholders, including civil society, are needed before making important local public health policy decisions. In addition, efforts to include local institutions and residents in the implementation process with the public officials are necessary to improve the situation.

As the result of correlation, the viewing rate of terrestrial broadcasting programs has a little bit affect on online VOD use. In addition, WOM(word of mouth) and online referral importantly influences to the picking with online VOD drama. The great popularity of main actors on drama affect a little bit the viewing of VOD drama but doesn't perfectly affect on it. However, the drama which is performed by great popular actors has positive affect on VOD use. This study result shows that the using of video depends on the effect of WOM, referral and commercial. The casting of a great popular actors plays role of the safeguard which affects viewing rate and add-value. That means the casting of a great popular actors doesn't connect with the success of release but the tool of defense from loss of profit.

This study was performed to explore the institutional treatment system by analyzing the pattern of musical actor's projection and aftereffect subsequent to the completion of performance. In-depth interviews were conducted with 22 top-class musical actors and actresses of the Republic of Korea. The result of the survey indicated that most actors and actresses suffer from projection and it's aftereffect such as depression for more than one month after performance, and that they tend to rely on self-healing based on self-diagnosis rather than seeking for professional counselling. The symptoms of projection were shown more strongly when the actors or actresses were taking on the role of main character, or acting as a negative or realistic character, or when expressing strong and extreme emotions. In this era of Korean culture, the result of this study implies that our country have to establish the actor's mental caring-related new law and private care centers supported enough funds to encourage the actors to receive more effective actor-friendly treatment service before and after the performance.

This study aims to analyze why South Korea has not used audit system but examination system and suggest policy reform for the system on the institutional context perspective. Institutional context is structured down to institutional legacy, motives, institutional constraints, actors' roles, and changed institution. I researched the literature on the subject and collected research materials from the Department of the Treasury and Audit Office website of New Zealand, Australia, United Kingdom, United States and South Korea. These were analyzed using for suggesting realistic and effective policy. Analysis showed that South Korea has used examination system due to institutional constraints and tried to increase reliability of financial statements by enlarging the meaning of examination, strengthening the ability of the Board of Audit and Inspection, enacting government examination standards, and making a comprehensive public announcement. Comparing with other countries where government audit systems are applied, there are still some vulnerable points in South Korea. In order to make up for the shortcomings, this study suggests several points: strengthening the ability of actors; systemizing internal control; expressing opinion; making a more comprehensive public announcement. It would be desirable for making further detailed studies of the points.

This paper analyzes the drought and restriction on water supply in Taebaek City during the winter season in 2008 using Actor-Network Theory. Actor-Network Theory emphasizes and brings into view the role and act of non-human actors as well as human actors in various environmental issues. The fact that only Taebaek experienced restriction on water supply for 88 days although the winter season drought in 2008 affected the whole nation, requires a synthetic analysis of both human and non-human actors and their relationships and networks embedded in Taebaek City at that time. This paper shows that both human and non-human actors including Taebaek City Hall, Korea Water Resource Corporation, Taebaek citizen, the water supply facilities, Gwangdongdam, obsolete water pipes, the topography of Taebaek, soil, the change of industry, and population interact one another transforming the geography of water in Taebaek. This study helps to understand the complex processes related to drought disasters at a specific local scale and to provide appropriate measures to drought.

The purpose of this thesis is to study on the philosophical analysis model and its methodological application of information systems research evaluation from critical realist perspective. Fist of all, I examine ontological epistemological methodological assertions of critical realism. Because the philosophy of critical realism is an opportunity for information systems study. I examine Dobson and Mutch's critical realist perspective on actors-structure model. I suggest a critical realist actors-praxis-structure model. This model provides the potential for a new approach to social investigations in its provision of an ontology for the analytical separation of structure and agency. Of most importance might be the incorporation of non-humans into the analysis of social interaction and of technology into the elaboration of structures. I also examine Tsoukas's critical realistic meta-theory of management. I suggest a critical realist IS management model. This model elucidate the nature of management and delineate the scope of applicability of various perspectives on management. The causal powers of management reside in the real domain and, taken together, their logics are contradictory, the effects of their contradictory composition are contingent upon prevailing contingencies. I analyze Carlsson's theory of design knowledge. His framework builds on that the aim of IS design science research is to develop practical knowledge for the design and realization of different classes of IS initiatives, where IS are viewed as socio-technical systems and not just IT artefacts. The framework proposes that the output of IS design science research is practical IS design knowledge in the form of field-tested and grounded technological rules. The IS design knowledge is developed through an IS design science research cycle. In conclusion, I think that IS actors-praxis-structure model, meta-theoretical IS management model, and IS design knowledge model according to critical realistic approach are very useful for IS research evaluation. Nevertheless, important problems are left not resolved.
