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.

The purpose of this study was to understand and develop various environmental designs to play a key roles in urban design, so that public green spaces remain vital with future changes. Variability in space, ecology, and society were analyzed based on research of variable environmental spaces in 11 selected studies conducted locally and abroad since the 2010s. Moreover, landscape characteristics, design methods, and design strategies were analyzed accordingly for each case. The results of the study showed that variability in landscapes provided various possibilities for spatial change and satisfied people's functional needs for spatial use. In addition, variable environmental design greatly compensated for the defects by solving the issues associated with fixed landscapes by increasing the flexibility of use and adaptability to the environment. This study showed that variable design is applicable to public green spaces; environmental stress; and variability in architecture, the environment, and landscaping, and it contributes to enhancing the sustainability and resilience of the environment.

This study evaluated the application of water quality management measures using the SWAT model and the effectiveness of the measures using the load duration curve targeting the Seohwacheon watershed located upstream of Daecheongho. As water quality management measures, artificial wetlands, reduction of neglected livestock, reduction of runoff from greenhouses, restoration of ecological rivers, application of LID technology, and management of point sources were applied. The applied technology evaluated the efficiency of water quality improvement measures by using the target water quality excess rate and the degree of load reduction for each sulfur through the load duration curve. The load duration curve was created by creating a long-term flow duration curve using SWAT and multiplying it by the target water quality. For the target water quality, the value corresponding to the 60th percentile was set as the target water quality using the 10-year data from the Okcheoncheon water quality observation point located in the downstream of Seohwacheon. Through this study, it was possible to confirm the applicability of various water quality measures through the SWAT model, and to examine the applicability of each period according to the sulfur through the load retention curve.

LID(Low Impact Development) facility classified as a social infrastructure can maintain landscape sustainability and functional sustainability through continuous maintenance and management. Since LID is a natural-based solution, the sustainability can be secured through the management of weeds, wastes and vegetation. The LID facility is distributed in the city and is an infrastructure that can be managed through citizen participation because of simple maintenance. Therefore, this study was conducted to investigate the maintenance factors affecting the sustainability of the LID facilities and to suggest measures for maintenance by investigating the participation of the peoples. The factors for landscape sustainability were derived to waste and weed management. Also the factors for functional sustainability were assessed to identification and management of dead bodies and selection of applicable soil and plant species. The citizens showed high agreement of more than 80% in the questionnaires on expanding and managing LID facilities, enacting LID ordinances, and participating in the national movement. The intention to participate in LID management linked to jobs was about 64%, indicating that LID could become a job for the vulnerable. Maintenance of the LID can easily be carried out by non-specialists, which can lead to citizen participation with low cost for each facility. The maintenance cost for citizen participation can be allocated from the social infrastructure management cost reduced by LID application of the local government and the social welfare budget of the central government.

This is a study about public-regeneration-architecture design of the 3rd world damaged by the development of capital society of the 20th century and from the perspective of economically poor, anti-capitalist development from non-profit design organization. Active among such non-profit design organizations, the sustainable design characteristics of public-regeneration-architecture of the Architecture for Humanity will be discussed. I help it so as a continuous possibility design to have been given to public-regeneration-architecture of the Architecture for Humanity is small, and I establish a construction space at a few costs to people in a situation to be environmentally interior economic, to be cultural, and I am large, and to be able to generate profitable construction by environment at activation of a local community and worldwide dimensions. I look through a sustainable design way of this study classifies it to cultural sustainability that ecology-cultural approach in the environmental sustainability result ecology - central approach, and how I was applied to materials of construction, color, a pattern, a construction method, space configuration etc. There is the meaning to try to analyze a characteristic of a sustainable design to have appeared to public-regeneration-architecture of the Architecture for Humanity which I make a symbiosis, and you can live on it how in the present cities that city poor floor will add to.

This study conducted a regulatory impact analysis regarding the introduction of the Korean version of REACH(Registration, Evaluation and Authorization of Chemicals). The direct cost of the Korean REACH is estimated at a total of 101 billion Korean won over the 11 year period. The cost includes pre-registration, testing, registration, Chemical Safety Assessment(CSA) and Chemical Safety Report(CSR), evaluation, and the authorization costs of 15,223 chemical substances produced and imported more than 1 ton per year in Korea in 2006. With regard to the benefit, the only public health benefit is included in the estimation. Based on the available foreign and domestic data, this study estimated that the economic values of public health benefits are in the range of 33.2~138.6 billion Korean won if only the savings of the National Health Expenditures are considered and it reaches 203.9~1,640.3 billion Korean won if the willingness to pay(WTP) for disease prevention is included. This study proved that the Korean REACH passed the cost/benefit criteria. The benefit-cost ratio of the Korean REACH, however, is estimated to be lower than its EU counterpart. Thus it is suggested that a rigorous study to reduce the costs to industry be required before the Korean government introduces the Korean REACH.

그간 Venture Debt은 벤처기업의 스케일업을 촉진하는 수단으로 인식되어 왔으나, 경기하강 국면에서는 투자유치가 여의치 않은 벤처기업에 유동성을 제공하는 자금공급수단으로서의 중요성이 부각된다. 한편, 2023년 3월 SVB의 파산으로 Venture Debt 취급기관의 지속가능성에 대한 우려가 부각되었다. 이에 본 연구에서는 대출재원의 지속가능성을 염두에 두고, 경기침체기 대안적 자금 공급수단으로서 Venture Debt 활성화방안을 연구하였다. 선행연구들은 주로 전통적 Venture Debt을 분석대상으로 하였으나, 본 연구에서는 벤처생태계의 성장과 경기사이클 변화에 따라 다양해지고 있는 Venture Debt을 유형별로 분석하였다. Venture Debt 유형을 전통적, Growth형, 유동성 지원형으로 구분하고, 각각 SVB, EIB(유럽투자은행), 해외 벤처유동성 지원사례를 중심으로 구조적 특징과 차이점을 분석하였고, 직접대출방식과 BDC 등 간접대출방식을 비교 분석하였다. 이와 함께, 경제성, 시장성, 대출재원 확보가능성 차원에서 국내 도입환경에 대한 실무적·법률적 검토를 병행하였다. 본 연구에서는 국내 활성화방안으로 채권형 BDC 활성화를 통한 민간재원 활용, 벤처전용 유동성지원 프로그램 마련, 제2데스밸리 극복을 위한 Growth형 벤처대출 도입, 독립형 워런트 발행을 위한 법적 근거 마련 등을 제안한다.
