Globalization has diversified ethnic composition thus increased the risk of conflicts and socio-political instability in global cities. However, still the status of community facility in a global city is unclear despite its critical role to build sustainable community in global era. In Seoul, as a reaction of globalization, 19 community facilities known as the 'Seoul Global Center' have been established since 2007 by Seoul Metropolitan Government. These facilities have started to provide basic foreigner services but been transformed to foreigner service hub with multiple functions in terms of a living, a business, a labour, etc. This study explores the role of the community facility for foreigners by using the Seoul Global Center as a case study, conducting a site observation, an interview(13 staff) and a questionnaire(148 visitors). The findings are the community facility functions as a 'global platform' in forms of a policy tool for implementing the urban globalization strategy, a mediator connecting foreign migrants with local communities, an applicant for successful settlement of foreign residents, an incubator that grows human and social capital, and a base for collecting and aggregating information on foreign migrants and forming new local identities.

본 연구에서는 핵연료 지지격자체의 재료인 Zircaloy-4 와 Zirlo 판재의 이론적 성형한계 예측모델을 제시했다. 먼저 인장시험 및 이방성시험으로 응력-변형률곡선과 이방성계수를 획득했으며, NUMISHEET 96을 따르는 돔장출시험으로 두 재료의 실험적 성형한계도들을 얻었다. 이론적 성형한계도는 성형한계모델과 항복조건의 영향을 받는다. Swift 확산네킹이론, Marciniak-Kuczynski 의 재료결함 모델, Storen-Rice 의 정점이론을 이용해 부변형률이 양인 구간에서의 성형한계 곡선을 구했으며, 부변형률이 음인 구간에는 Hill 의 국부네킹 이론을 적용했다. 또한 재료이방성을 고려하기 위해 Hill 48, Hosford 79 항복조건을 사용 했다. Swift 확산네킹모델 (Hill 48 항복조건 적용)과 Hill 모델은 각각 변형률비가 양과 음인 영역에 대해 Zircaloy-4의 성형한계도를 비교적 정확히 예측하며, Zirlo의 성형한계도는 Hosford 79 항복조건 (a = 8)을 적용한 Storen-Rice 모델로 나타낼 수 있다.

With the passing of Special Act on Promotion and Support for Urban Regeneration (will be hereafter referred to as the Urban Regeneration Special Act) in December 2013, urban regeneration projects have begun in full scale. 13 regions including Jongno District, Seoul were selected as the urban regeneration leading area in 2014 and 33 regions as urban regeneration general regions in 2015 to push ahead a nationwide urban regeneration front supported by government funds. However, it is not clear if these urban regeneration projects will be revitalized by the sole means of government's financial support. Above all, cooperation among all interested parties including the central government that is propelling urban regeneration, local governments, state corporations, private entities, and citizens is urgent. In an urban regeneration project, delegation between state and private entities is absolutely crucial. The central government and the pertinent local government must provide their support by forming new policies and repairing old institutions that are right for urban regeneration, securing the necessary subsidy, and outsourcing government-owned land development. A state corporation must play its part in every aspect that requires public character such as an overall project management of an urban regeneration project, cooperation with the local government, and infrastructure installation. The private stakeholder must share his private capital and know-hows as a construction investor and a development businessman to make possible a successful urban regeneration project. In order for these public and private entities to cooperate with one another, it is necessary to reestablish the role of a public developer and contemplate running an urban regeneration project that permeates public character through a public developer.

Historically, college campuses have played a role of a city, and the development pattern of various forms and functions of cities was found in the growth stages of campuses as well. In this way, campuses developed in close relationships with our lives and such a characteristic can be confirmed in a number of cases in and out of the country. The strategic concept of such expansion is shown in the strategic classification through a master plan. This research examines concepts of major universities in the metropolitan area of Korea for promoting campus expansion and proposes implications through them. The results drawn from the research are as follows. Firstly, various developmental directions should be sought in aspects of planning, programming and economics for campus expansion with the complex application of such factors. Secondly, the multi-campus strategy of past localization era is changing into the concept of forming a global campus materializing itself as the planning strategy of internal campus. Thirdly, the physical barrier is being dissolved as a way to promote the relationship with local communities, and particularly, the management strategy of constructing new buildings in connection with local communities is the leading measure of materialization. Lastly, the development of underground space is actively carried out due to the limitation of ground physical space through which a role of establishing new campus order along with securing space is pursued.

The purpose of this study is to identify the conflict between residents and governments in partnership arising from the designation of National Important Agricultural Heritage for Damyang Samdari village and to suggest directions for improvement. To this end, residents of Samdari Village in Damyang, designated as an important national agricultural heritage, were interviewed. Interviews were analyzed through grounded theory, categorized into open coding, axial coding, and selective coding, and a paradigm model was constructed. Through this, the central phenomena of resident participation patterns currently appearing in the village were identified, and causal, contextual, and intervening conditions were analyzed. Causal conditions were analyzed as one-sided administrative treatment, assortment matching project, one-time plan, excessive dependence of residents and economic damages of residents at the beginning of the designation of national important agricultural heritage. As a result, conflict between residents and local governments occurred as a central phenomenon, and contextual conditions such as decline in the competitive of bamboo resources and frequent change in managers were also affecting the central phenomenon. As intervening conditions to alleviate the central phenomenon, there are local government's purchase of bamboo fields and fragmentary business effects. The action taken by the residents and officials in response to a fixed conflict is called an action-interaction strategy. Residents refused to change and settled in reality, and local governments avoided conflict. From the beginning of the designation to the present, the villagers gradually lost interest in the National Important Agricultural Heritage due to problems and conflicts that occurred in the process of forming a partnership in the National Important Agricultural Heritage project. Based on the analyzed model, a plan to build the partnership standards on Damyang bamboo field to secure the sustainability of the field and increase the practicality of resident participation, that is partnership, was suggested.

Health centers provided intensive health care services for local residents according to changes in the times and environment. Public health centers were given various roles such as medical treatment, administration, and service, and the demand for functional reorganization has emerged. We analyzed the literature on the functional restructuring of public health care institutions. In addition, the current status of medical services, which is the main function of institutions, will be analyzed through health insurance statistical data, and detailed contents will be analyzed according to regional types and income levels. As a result of the analysis of medical services at institutions, the total number of patients was 2,238,000, and the number of visits was 11,806 times. Total medical expenses were 169.6 billion won, of which 132 billion won was found to be benefit. When analyzing the number of patients per institution, public health centers had the largest number of 4,326, and the share of benefit was also the highest at public health centers. It should focus on the function of providing local health and medical services related to health promotion and disease prevention in the community. This functional reorganization of public health centers can contribute to forming cooperative relationships with private medical institutions in the local community. For this, first, to establish the role, essential functions for public health centers for preventive health management are established. Secondly, regular manpower expansion and flexible manpower management are required in the human resources sector. Finally, in the organizational sector, it is necessary to establish a step-by-step organizational system according to environmental changes.
