This paper reviews available techniques for monitoring corrosion of steel in concrete. The need for early detection and diagnosis of corrosion related deterioration in reinforced structures is widely acknowledged. This is particularly important in reinforced concrete structures on account of the economic and social significance of the problem. The current generally used on-site procedure for corrosion monitoring of reinforced structures employs a method of half-cell surface potential measurements. While the technique has provided a useful means of delineating areas of high or low corrosion risk, there are difficulties in its use and interpretation when assessing rates of deterioration. Electrochemical techniques are by far the most suitable for corrosion monitoring purpose and meet most of the requirements. The aim of this paper is to describe the electric resistance sensor(ER sensor) and electrochemical techniques employed to monitor and estimate corrosion rates of reinforcement. Early detection and diagnosis of corrosion hazards allows preventive measures to be taken, hence the typically expensive repair of severely deteriorated structures can be avoided.

Recently, the deterioration due to salt damage and carbonation as the main factors of deteriaoration of the domestic reinforced concrete structures has been increased. Also the national and social concern about the durability recovery of the deteriorated reinforced concrete structures is geratly being raised. Therefore, it is the final purposes of this study to develop the performance evaluation technique for durability of reinforced concrete structures deteriorated due to salt damage and carbonation with the proposal of the service life prediction method for the investigation and diagnosis of reinforced concrete structures, and accelerated test in Lab.

The paper critically examines resource mobilization theories, frame theory, and new social movement theories, and proposes studies on the spatiality of the social movements as one potential to mitigate the limitation in these theories. The resource mobilization theories and the frame theory, the strategy-oriented approaches, lack contextual understandings of the origin of social movements. While new social movement theories provide macro-scale analysis and the structural explanations of the origins of social movements, they have covered limited geographical areas. The spatiality of social movements promotes deep understandings of local differences, and contexts in and through which grievances are constructed and collective actions are organized. Physical structures and symbolic representations of places are often created and utilized as social movement strategies. The spatiality of social movements can be a useful conceptual tool to explain the diversity and the dynamics of social movements.

Through the research, we found that the organizational systems of social enterprises in Europe have both properties of limited companies and stock companies in traditional organizational structures such as cooperatives, mutual companies and associations. However, social enterprises pursue interests of entire community, allowing the interested parties to join them in comparison with cooperatives. And for finance, most of the countries mainly use public fund such as national grants, but they are using more sales revenue. However, in our country the organizational systems of social enterprises have been introduced as the government and academic circles discussed expansion of social employment within a short period. So Korean enterprises tend to depend on national support rather than profitable activities for finance. Therefore, we need to develop a Korean convention or social agreement for the organizational systems of social enterprises. Furthermore, it is important for social enterprises to secure safe finance through development of social services and social cultures such as donation.

Purpose: The purpose of this study was to examine the impairments of body structures, activity limitation, and participation restriction. In addition, we wanted to provide basic data on correlation between impairments of body structures, activity, and participation in Disabled Persons Living at Home. Methods: After selection of 128 people with physical disabilities more than the third level and brain damage disabilities living at home, we conducted testing for impairments of body structures, activity, and participation, according to the ICF checklist. Results: Impairments of body structures was highest in the upper and lower extremity. 2) Mobility, domestic life, and self care were more limited. 3) Also, the structure related to movement showed correlation with mobility, domestic life, and self care. Conclusion: We observed differences in participation and activities of persons with disabilities Living at Home depending on the impairments of body structures. After thorough review of the status of Disabled Persons Living at Home, we decided to appropriate support and social services.

Due to the large volume and generally as a public building, the damage of large-span space structures under various non-conventional loads will cause greater economic losses, casualties, and social impacts, etc. Therefore, it is particularly important to evaluate the seismic performance of large-span space structures. This paper taked a multipurpose sports center as an example and considered its synergistic deformation based on the method of equivalent damping ratio. Furthermore, The ABAQUS software was used to analyze the time-history and energy response of the multipurpose sports center under the action of rare earthquakes, and proposed a quantitative damage index to assess the overall damage of the structure. Finally, the research results indicated that the maximum inter-story drift ratio of the multipurpose sports center under the action of rare earthquakes was less than its limit value. The frame beams presented different degrees of damage, but the key members were basically in an elastic state. The bearing capacity did not reach the limit value, which satisfied the intended seismic performance target. This study taked an actual case as an example and proposed a relevant damage evaluation system, which provided some reference for the analysis of the seismic performance of large-span space structures.

The purpose of this study is to develop promotion strategies for revitalizing mountain eco-villages through social economic support. In order to fulfill this purpose, this study analyzed operation conditions, income creation structures of 240 mountain eco-villages formed by Korea Forest Service, and reviewed systems for social economic support. As summarized in research outputs, this study confirmed that the activities of organizations for joint projects had not been properly implemented due to the absence of supporting systems following the construction of mountain eco-villages. In addition, 159 villages formed as experience villages could not be qualified for enterprise systems due to aging population and absence of network systems. As for income creation, as indicated by comparing net incomes for joint projects calculated based on the classification of village management evaluation, the average net income of 51 highly-rated villages was 22 million Won and that of 128 moderately-rated villages was 3.5 million Won. Experience-based projects and the sales of processed forestry products made by young adult associations or women's societies were major sources of income, and the absence of inner economic bases or villages' jobs caused young adults and returned farmers to focus on working for outside economic activities. Finally, this study developed strategies for mountain eco-village's social economic promotion and suggested four stages of social economic revitalization provisions.

With a view to contributing to the epistemological and methodological debates in Southeast Asian Studies, the aim of this paper is to examine critically the epistemic concepts and approaches in the social sciences and then to seek an epistemic reflexivity and its potential methodological applications to Southeast Asian Studies. Although the field of social sciences has attempted to search for a means of tackling the ontological and epistemological dilemmas in its major paradigms, Southeast Asian Studies still demands a more 'actor-centered' epistemic account of reflexive interaction between actors and social structures. Bearing in mind the need for a more 'actor-centered' epistemic approach, this paper continues to discuss the 'epistemic reflexivity' in the social sciences and its potential applications to Southeast Asian Studies. In this paper, I will consider 'epistemic reflexivity' as an alternative methodological orientation. It emerges as interlinked with the ontological standpoint of what is called 'reflexive approaches' and its application to the detailed 'reflexive methodology' which I am proposing in this paper. In doing so, this paper discusses the autobiographical experiences of the author arising from his ethnographic field research in North Sulawesi, Indonesia and their implication for a reflexive methodology in Southeast Asian Studies. In conclusion, the paper argues that we need a 'more actor-centered' epistemic framework to compensate for the epistemological and methodological dilemmas in the social sciences and the alternative framework will equip Southeast Asian Studies with a reflexive methodology relevant to the life-dynamics of the social world in the process of developing its inquiries, methodological technics, analysis, and validation.

In order to examine the causes of the social policy changes in Korea during the late of 1990s, this study tries to compare the social policy decision-making structure between Kim Yong-Sam Government and Kim Dae-Jung Government. This study applies policy network analysis method which measures the relation and power structures of policy actors and as a result shows the characteristics of the policy making structure. Analysing the 6 policy domains and 52 policy events, this study finds that the importance and location of veto points which were created by the social policy decision processes have changed. In Korea, social policy decision processes have been produced power structures in which Ministry of Finance and Economic Planning Board have played a decisive role. In result, these executives can have controlled policy making processes and had veto power, i. e. veto points in policy decision-making structure. But, during Kim Dae-Jung government, accountability issues of financial crisis and reorganization of ministries have changed the importance and location of veto points. Pro-welfare groups of civil society got a chance to penetrate policy decision-making structure during that time. This study argues that these changes of policy decision-making structure may be associated with the social policy changes in Korea during the late of 1990s.

The main purpose of the study is to explore the implications of Recognition Paradigm for domains of social work, especially focusing on the arguments exchanged between Axel Honneth and Nancy Fraser, two eminent scholars in this field. The Recognition paradigm, which is an alternative perspective in practical philosophy developed to cope with the changing socio-political situations in the late modern society, is providing the domain of social work with a lot of important theoretical and practical implications as well. In particular, Honneth's recognition theory which considers the recognition as a basic prototype in human development and construction of society is able to clarify the fundamental mission and territory the social work profession is to pursue. But for the meanwhile, Fraser's dual perspective of justice, which is an extended version of redistributive justice introducing the recognition component in it, can suggest diverse practical strategies to confront complex injustice-making structures effectively in the later modern society. In spite of these abundant implications in both theoretical and practical areas, the recognition paradigm still save several fundamental considerations for social work, such as the real meaning of the recognition in social work, the exact population from whom social work seek to get recognition, and the adequate strategy, so-called "recognition struggle" which social work is to employ to acquire the recognition.
