In this study, the effect of wake on the energy production of a downstream wind turbine was analyzed on the base of operation practices of wind farm in the coastal complex terrain which has 2 row array of wind turbines. And changes in the variation of wind speed and turbulence intensity was analyzed. In case wind turbines are spaced 4-rotor diameter-apart in the prevailing wind direction, reduction in energy production was confirmed due to the decrease of wind speed and the increase of turbulence intensity by wake. Especially a radical change of wind direction caused wind turbine a sudden stop and energy production significantly reduced. It is considered improvement of yaw brake can prevent the sudden stop and increase energy production.

This study has been made to execute a research in order to lead the improvement of indoor air quality, examining the indoor ventilation characteristics by using a numerical analysis method. To this end an extensive parametric investigation are made according to various external flow variables such as main wind direction and wind speed by season, building layout design, and location of ventilators, etc. in Daedeok Techno Valley, one of large-scaled apartment in Daejeon. It is observed there was a significant difference of main wind direction between summer and winter. The main wind direction in summer was a south wind, and on the contrary the direction in winter is northnorthwest, which is similar to the average main wind direction for 10 years. One of the important calculation results is that the change of wind direction causes a significant effect on the apartment ventilation by the change of pressure difference around each complex of apartment. In case of favorable area of ventilation, the indoor ventilation rate can meet 0.7 ACH from the standard value only with natural ventilation. On the contrary, in other area the value was much lower than the standard value. If the calculation result applies to the design of layout apartment or placement of ventilators, it will be greatly helpful to the energy saving because it can be parallel with the natural ventilation to help securing ventilation rate, not much depending on the mechanical ventilation.

최근 처리해야 하는 정보의 양의 급속히 배가됨에 따라 디스크 배열(disk array) 시스템에서 사용하는 디스크의 수가 증가되는 경향을 보이고 있다. 그러나 많은 수의 디스크를 이용하여 디스크 배열을 구성하게 되면 디스크 오류 발생 확률을 높이는 결과로 이어지게 된다. 이 논문에서는 많은 수의 디스크를 사용하는 환경에서도 높은 신뢰성을 제공하기 위하여 DH(Diagornal-Horizontal) 기법이라 불리는 두가지 형태의 이중 패리티 배치 기법들을 제안한다 제안한 기법들은 사선 패리티와 수평 패리티를 인코딩하여 이용함으로써 디스크 배열에서 이중 디스크 오류의 복구가 가능하다. DH 기법들의 특징은 알고리즘이 단순하고, N을 임의의 소수라고 할 때 N 또는 N+1개의 디스크를 기반으로 쉽게 구현할 수 있다. 기본적으로 제안하는 기법들은 검사정보 저장을 위해 최적의 디스크 공간을 사용하고, 인코딩이나 디코딩 과정에서 단지 XOR 연산만을 필요로 하기 때문에 하드웨어의 수정 없이 기존의 디스크 배열 시스템에 쉽게 응용할 수 있다. 더욱이 치명적 오류를 방지할 수 있는 두 오류 디스크에 대한 복구 시간은 디코딩에서의 XOR 연산수를 최소화함으로써 신속하게 처리할 수 있다. 결과적으로 제안하는 기법들은 디스크 배열 시스템에서의 치명적 오류 확률을 낮출 수 있는 효과적인 방법이다.

The purpose of this study is to define the characteristics of multi-family housing layout in Cheongiu city. The layout were classified into three types: parallel, courtyard and mixed. Of 43 housing estates constructed in the 1980's, the parallel types consist of 34 housing estates, representing 79%, the mixed types 8 housing estates (17%) and the courtyard types 1 housing estate (2%). The dominant form of housing layout during that period was the parallel type, followed by the mixed type. Of the 47 housing estates of the 1997s, the parallel types are 20 (43%), the courtyard 17 housing estates (36%) and the mixed 10 housing estates (21%). Of all of the 90 housing estates, the parallel layout takes 60%, followed by the courtyard type and the mixed type of 20%, respectively. The survey results indicate that the parallel layout is the most dominant form of the multi-family housing built in the last two decades in Cheongju. However, from the middle of the 1990's, there has been a steady increase in courtyard layout and there have been various types of mixed layout. It is claimed that the adoption of various form of housing layout reflects occupants'demand of more outdoor space leer community needs.

In Korea, there is a need for safe and convenient elderly housing so that older people can enjoy a good quality of life and perform various daily activities while they maintain their health and well-being. Thus, this study is to suggest community -based housing settings for the elderly. We analyzed living space characteristics of the Continuing Care Retirement Communty(CCRC) in the U.S. In particular, we focused on CCRCs in the Oregon area and examined two types of settings: 1) a tower setting and 2) a town setting. The CCRC living arrangements include independent living, assisted living, nursing care, and memory care. We visited six CCRCs in Oregon during January through May in 2015. The field observations and floor plan surveys were conducted for data collection. The data analysis revealed that there are two types of arrangements: the suburban type and the urban type. Element analysis of the living unit designs for each CCRC type demonstrated typical space configurations. It was found that home care services were provided from local communities. It is suggested that community-based housing for the elderly should include mixed housing types so that community facilities can be shared. Medical services in the community were offered through healthcare institutions, disease prevention centers, welfare centers, and sports facilities. In order to apply these community-based care systems to elderly Korean housing, it is important to develop a community based on independent homes that share services and welfare facilities.

This study draws economic expense factors according to the influence of generation resulted from slipstream and the arrangement of the complex when arranging and designing the complex for offshore windpower development as a model of 50MW offshore wind farm and conducts economics analysis. According to the result of the analysis, O (Optimize) arrangement was the one that has the highest generation for having the best windpower resources in terms of design and being least affected by slipstream; however, the arrangement requires expensive submarine cables and high installation cost. Therefore, according to the analysis of economics, it was thought that 50MW complex should have less economics as BC ratio 0.95 than the series arrangement of main wind direction and I+80 series arrangement would be rather more economical. This economics evaluation provides comparison according to the arrangement of the development complex considering the uncertainty of the electricity price and gross construction cost. And it is expected that the result of economics evaluation would greatly differ by installation capacity, and the reason is that the cost of electric infrastructure takes up a higher portion than the gross construction cost of the development complex. The only way to compensate this part is to make the windpower development complex larger. It seems that it will be necessary to enhance spot applicability to evaluate economics afterwards and pay consistent attention to and conduct follow-up research on the economics evaluation of the complex construction.
