Rail station premise's unused land speaks unused space long period among that is station porter underwear space. Also, will may see that two is also unused land if is operated as inefficient occupying a lot of spaces unnecessarily. These space have used by profit making business and station development putting first past. But, necessity of more active business effort is brought ill efficiency side of land. Unused land's efficient practical use is method that can increase railroad property. Therefore, in this study, define shortly about composition of reciprocal space, and presents unused land's practical use plan in station.

유휴공간은 기존 도로의 선형개량 및 신규노선 건설, 도로 확장공사 등으로 도로 본래 기능을 상실하여 방치된 도로 부지로 추가적인 활용이 가능한 공간이다. 그러나 현재 일부 유휴공간은 과적 검문소, 자재 적치장, 차량 대기소 등의 소극적인 유지관리와 활용이 이루어지고 있지만 대부분의 유휴공간에 대한 체계적인 관리방안과 활용방안이 필요한 실정이다. 본 연구에서는 공간정보 오픈 플랫폼(브이월드)를 이용하여 유휴공간의 입지조건, 지형특성, 지역 및 문화 특성을 분석하고 유휴공간의 유형을 분류하기 위한 기준을 정립하였다. 유휴공간의 유형에 따라 공간정보 오픈 플랫폼을 이용해 3차원 모델링을 수행하고 주변 환경과 경관을 고려한 활용 및 개발 모델을 제시하였다. 향후 강원권 국도 유휴공간의 개발계획 및 설계방안을 도출하여 유휴공간의 활용에 도움이 되고자 하였다.

In this study, the author suggests utilizing unsold and unused land as temporary commercial parking lots as a way to raise funds for active public transport use. In addition, reasonable parking fee scheme is suggested by estimating marginal parking fee and marginal parking distance for the commercial parking lots based on the CVM. The author conducts a survey to investigate citizens' opinion on utilizing unsold and unused land in the urban development project area as temporary commercial transport facilities such as parking lots. Based on survey outcome, travel behavior and requirements are analyzed and marginal parking fee and marginal parking distance are estimated through the Contingent Valuation Method (CVM). The results are as follows: in the single-bounded dichotomous choice model, people are willing to pay 216 KRW for 165m in average for 10 minutes and their willingness to pay goes down against reaching distance to the parking lots from 365 KRW for 50m, 295 KRW for 100m, 173 KRW for 200m, and 51 KRW for 300m; in the double-bounded dichotomous choice model, people are willing to pay 285 KRW for 165m in average for 10 minutes and their willingness to pay goes down as well against reaching distance to the parking lots from 310 KRW for 50m, 297 KRW for 100m, 272 KRW for 200m and 248 KRW for 300m. It is clearly appeared that people's willingness to pay goes higher as distance to reach the parking lots goes shorter.

In this study 'forest design in waterside unused land' of 'waterside area' in the specificity that multilateral, including landscape, recreation, social and environmental aspects in the space, taking into account by multiple factors :Raise 'practicality' than a functional management and police to hang out with, each element is usually way to improve the beauty. There is currently carried out waterside green area creation, which is artificial plantation and open spaces only emphasizing 'landscape' with lacking multi-function purpose, as a 'forest design in waterside unused land' strategy but it should be lowered by performance in this strategy. And the study suggested a strategy which prepared cultural and social infrastructure to be able to attract different fund and build local character as an alternative demand plan considered environmental character as a top priority.

Urban green areas are generally composed of relatively small and fragmented patches, but it is a critical factor for the quality of an urban environment. They have positive effects such as increasing green connectivity, reducing runoff, and mitigating urban heat. But, there is a lack of urban greening plans that consider the comprehensive effects of green space in real urban areas. To fill this gap in this literature, this study identifies a planning model that determines the optimal locations for maximizing green areas' multiple effects(e.g., heat mitigation and enhancement of connectivity) by using unused lots. This model also considers minimizing costs using meta-heuristic optimization algorithms. As a results, we finds 50 optimal plans that considers two effects within the limited cost in Nowon-gu. The optimal plans show the trade-off effect between connectivity, heat mitigation and cost. They also show the critical unused land lots for urban greening that are commonly selected in various plans. These optimal plans can effectively inform quantitative effectiveness of green space and their trade-off. We expect that our model will contribute to the improvement of green planning processes in reality.

도시 내 유휴지 및 하천, 도로변과 같은 공공시설부지는 오랫동안 도시민에게 도시농업 공간(텃밭)을 제공해 왔다. 그러나 유휴지와 공공시설부지에서 이루어지는 대부분의 경작은 불법이어서 텃밭 이용자와 토지소유자 그리고 공공시설 관리자간의 갈등을 유발하고, 도시경관의 질 저하, 환경오염, 공공시설물 훼손 등의 문제를 야기하고 있는 실정이다. 따라서 본 연구는 도시 내 공공시설부지 등에서 무단으로 경작되는 도시농업을 양성화할 수 있는 방안 제시를 목적으로 도시지역에 다양한 형태로 산재한 텃밭의 분포 및 이용 실태를 조사 분석하였다. 조사는 대구광역시 시지지역을 사례지로 선정하여 현장 조사, 텃밭 이용자 및 주말농장 운영기관 담당자와의 면담을 통해 이루어졌다. 연구 결과, 도시텃밭은 접근이 쉬운 주택가 인근의 개발이 제한된 녹지지역에 주로 분포했으며, 주거지에 인접할수록 텃밭의 분포수가 증가하는 것으로 나타났다. 토지이용 유형별로는 농경지에 분포하는 텃밭의 비율이 월등히 높았으나, 도로, 하천 등 공공시설부지에 분포하는 비율도 농경지의 3분의 1을 상회하였다. 텃밭을 경작하는 사람들 중 개인 소유 토지를 무임 경작하는 사람들의 비율이 가장 높았고, 국 공유지 무단경작 비율이 다음으로 높았다. 도시 내 유휴지와 하천, 도로, 철도 등 공공시설이 위치하는 국 공유지를 텃밭으로 무임, 무단 경작하는 사람들 대부분은 노인으로 나타나, 노인 여가 공간으로서의 도시텃밭의 잠재력을 확인할 수 있었다. 본 연구는 조사대상지가 특정 지역에 국한된 점, 텃밭의 규모를 실측하지 못한 점 등의 한계가 있으나, 도시텃밭의 분포 및 이용 특성을 파악하여 불법으로 경작되는 도시농업의 양성화 및 제도적 수용 필요성을 제기했다는 데, 그 의의가 있다고 생각된다.

The purpose of this study is to analyze the characteristics (COP) of the heat pump system for various operating conditions with the use of seawater heat source and exhaust energy. To accomplish the goal, first of all, the computer simulation for heat pump system is carried out. The heat pump system model is made of a waste heat recovery system and a vapor compression refrigeration system, and the working fluid is R-22. The model calculated the change of COP with the variation of temperature and flow rate. The COP and the plate heat exchanger (PHE) area of the heat pump system are considered moderately high in the condensation temperature of $25^{\circ}^C$ and the evaporation temperature of $2^{\circ}^C$ in indoor culture system. The simulation results will be used effectively for the design and the performance prediction of heat pump system using unused energy in a land base aquaculture system.

Recently, There has been much discussed about unused space. This space can be used in a variety of ways. Utilizing it as a facility, craft shop, and utilizing renewable energy generation facilities. Especially, in terms of climate change should be supplied renewable energy. Renewable energy needs to be developed in terms of responding to climate change, and the recent Paris agreement is also emphasizing the importance of renewable energy. In particular, renewable energy needs to be widely disseminated. And renewable energy is limited space. In this regard, idle land can provide opportunities for securing new renewable energy generation facilities. The introduction of new and renewable energy facilities in idle space can enhance the self-sufficiency rate of the local community, which is significant in terms of responding to climate. In this study, to investigate the possibility of utilizing a unused space for a photovoltaic power generation facility, we investigated the amount of electricity which could be generated through photovoltaic power generation, and the economic effects, using a RETScreen model. The results showed that 9,738 MWh of power can be generated and that $4,540tCO_2eqcan$ be saved. Regarding the economic effect, the net present value of the facility was shown to be 2,247,389,020 KRW. As the net present value was shown to be positive, we believe that the installation of a photovoltaic power generation facility in an unused space would have a positive economic effect. We found the net present value following the fluctuation of the SMP price to be positive, though there was some variation. However, as the economic efficiency was shown to be low because the net present value in relation to the maintenance costs was negative, we believe that maintenance costs must be taken fully into account when evaluating economic efficiency. In particular, as subsidies can be used to cover maintenance costs which must be factored into photovoltaic power generation, we believe that photovoltaic power generation can have an economic effect. Because spaces not currently in use can have a positive economic effect as renewable energy power generation facilities, and can also contribute to the reduction of greenhouse gas emissions, unused spaces are thought to greatly help local governments to cope with climate change as well as reinforcing their related capabilities. We believe our study will help local governments with decisions relating to unused real estate utilization in the future.
