The global energy paradigm is rapidly changing by centering on carbon neutrality, and wind energy is positioning itself as a leader in renewable energy-based power sources. The success of onshore and offshore wind energy projects focuses on securing the economic feasibility of the project, which depends on securing high-quality wind resources and optimal arrangement of wind turbines. In the process of constructing the wind farm, the optimal arrangement method of wind turbines considering the main wind direction is important, and this is related to minimizing the wake effect caused by the fluid passing through the structure located on the windward side. The accuracy of the predictability of the wake effect is determined by the wake model and modeling technique that can properly simulate it. Therefore, in this paper, using WindSim, a commercial CFD model, the wake diffusion pattern is analyzed through the sensitivity study of each wake model of the proposed onshore wind farm located in the mountainous complex terrain in South Korea, and it is intended to be used as basic research data for wind energy projects in complex terrain in the future.

경기도 김포시의 변화가 예사롭지 않다. 한강신도시가 들어서면서 신흥 주거지로 명성을 높이더니, 이제 경인아라뱃 사업이 본격화됨에 따라 산업계의 시선 역시 집중시키고 있다. 경인아라뱃길 사업이 산업계의 주목을 받는 가장 큰 이유는 김포터미널(김포 고촌읍 전호리 일대)에 조성될 '김포물류단지' 때문이다. '김포물류단지'의 북측에는 마리나를 중심으로 관광, 레저 및 수변상업시설이 배치된다. 또 남측에는 컨테이너 부두와 연계한 장고 집송시설 등 물류시설이 들어선다. 가히 문화와 산업이 어우러진 수도권 서부지역 최대의 물류소통 전진기지가 등장하는 것이다. 이 전진기지의 중심에는 삼성에버랜드가 시공하고 있는 '수도권 통합물류센터' 가 있다. 이 센터는 연면적 $63,571m^2$의 물류창고로, 김포물류단지 내에서는 최대 규모를 자랑한다. 즉 김포물류단지를 대표하는 건축물인 셈이다. 때문에 삼성에버랜드는 큰 책임감과 자긍심을 갖고 시공에 임하고 있다. '철저한 안전관리' 로 김포물류단지의 랜드마크를 선보이겠다는 이곳 현장을 찾아가 봤다.

The purpose of the research is to track the morphological transformation of apartment complex sites in Busan, especially focusing on building arrangement on apartment complex sites. Though there have been numerous studies regarding apartment housing, only few studies have been performed about the building arrangement. The arrangement has been poorly treated and not well disclosed as compared with other apartment-based research such as form of residential towers, floor plan, etc. The building arrangement is one of the most critical decisions at the early design stage and is affected by numerous social aspects such as building/zoning code, market demand, cultural preference, etc. Thus, the transformation of the arrangement may provide the hint for the change of socio-cultural demands of apartment housing. The research has been done on the existing 269 apartment complexes which have been built through 2016 in Busan. There are three categories set for analysis: relationship between buildings, relation between road and buildings, and the building arrangement along site perimeter. The result shows that significant change has occurred since 2000s; the arrangement has become diverse from three types to seven types. The early model of parallel or lattice types have been dominant until 2000, but the skewed one replaced the parallel or lattice types in Period V and Period VI, which is from 2001 through 2016.

This paper describes a study which was undertaken in Ulsan City. The modified SLP procedures consider the quantitative flow aspect of the facilities layout problem as well as the qualitative closeness rating aspect. Conclusions are drawn as to the effectiveness of the proposed model in providing Ulsan City with better means of making the facilities location allocation decision for Industrial Technology Research Park.

In order to effectively secure site suitability for the development of large-scale offshore wind farms, it is essential to minimize the environmental impact of development and analyze the conflicts of benefit between social, ecological, and economic core values. In addition, a preliminary review of site adequacy must be preceded in order not to collide with other used areas in the marine spatial plan. In addition, it is necessary to conduct local meteorological characteristics analysis including wind resources near Jeollanam-do area before project feasibility study. Therefore, wind resource analysis was performed using the observation data of the meteorological mast installed in Wangdeungnyeo near Anmado, Yeonggwang, and the optimal site was selected after excluding geographical constraints related to the location of the offshore wind farm. In addition, the annual energy production was calculated by deriving the optimal wind farm arrangement results suitable for the local wind resources characteristics based on WindSim SW, and it is intended to be used as basic research data for site discovery and selection of suitable sites for future offshore wind farm projects.

Rental housing complex is the complex built up for stable supply of residence for low income class and it offers significant implication to the Korean society in the residential welfare aspect, and as it has been the continuous subject of dispute and interest, such an issue has stirred significant interest on residential environment of low income class. It has made along with the residence history of Korea, but in the aspect of quality of life for low income class, there is a significant difference with generally supplied residence, and it ultimately continues with the disputes with the rights on quality of life for low income class. For this study, a total of six rental housing complexes were implemented with the field survey and it also had the survey on facility utility and physical environment. Use of facilities is influenced by the arrangement plan on physical environment of the complex, and in particular, it is influenced by the relationship of the main entry to the complex and surrounding complexes. In addition, following the level of design and facility plan of community space and it has confirmed the need to accommodate the request of users through securing the integrated function of community facilities.

An optimal layout condition of the offshore wind turbines is studied by using the response surface analysis which is a kind of the design of experiments. Based on the assumption that total 36 turbines would be installed in the offshore wind farm, the number and distance of the rows and columns are used as the design variables and the efficiency decrease of power generation due to the wake decay by the interactions of turbines and the installation cost of the internal electric grid are considered as the objective functions of the response surface analysis for the layout design of turbines. Useful design information can be derived by analyzing the relationship between the design variables and target functions. It is found that the row number and the distance between rows should be minimized, and the optimal distance between columns should be estimated and adopted to the layout design within the specified design range in order to ensure the economics for the offshore wind farm.

It is necessary to develop a new location model to support the application of smart technology and confluence in the 4th industrial revolution era. In this study, we propose 'network-type industrial complex' as a method to link several industrial integrated spaces which are dispersed in an area. As a result of conducting a survey of companies in order to develop a new location model, about 89% of companies recognized the necessity of network-type industrial complex. As a condition for activation of the industrial complex, 'complementary function formation', and 'convenience of nodular transportation' were selected. It is expected that it will be possible to supply low-cost, high-efficiency industrial complexes through opening and linking with urban space and infrastructure sharing.
