본 연구는 대구시 중소기업을 중심으로, 아파트형 공장의 입지요인 및 정책요인이 입주의사에 미치는 영향을 분석하는 것을 목적으로 한다. 본 연구의 주요 결과는 다음과 같다. 첫째로, 설문조사 분석결과를 보면, 응답기업의 58.2%가 아파트형 공장에 입주할 의사가 있는 것으로 나타났다. 둘재로, 입지요인에 대한 요인분석 결과, 네트워크, 입주비용, 접근성, 입주공간, 노동력 등 총 5개의 요인이, 정책요인에 대한 요인분석 결과, 경영지원정책, 금전지원정책, 행정지원정책 등 총 3개의 요인이 추출되었다. 셋째로, 로짓 희귀분석 결과, 입지요인이 입주의사에 미치는 효과에서 대구지역 아파트형 공장의 잠재수요자인 응답기업들의 아파트형 공장 입주의사에 통계적으로 유의하게 영향을 미치는 입지요인은 없으나, 입주비용 요인은 입주의사에 약하게 영향을 미치는 것으로 판단된다. 또한, 정책요인이 입주의사에 미치는 효과분석 결과, 세제지원, 금융지원, 임대료 지원과 같은 금전지원 정책이 대구지역 아파트형 공장의 잠재수요자인 응답기업들의 입주의사에 통계적으로 유의하게 영향을 미치는 것으로 나타난다.

This research presents an in-depth analysis of location planning of the solar-hydrogen power plants for electricity production in different cities situated in Kerman province of Iran. Ten cities were analyzed in order to select the most suitable location for the construction of a solar-hydrogen power plant utilizing photovoltaic panels. Data envelopment analysis (DEA) methodology was applied to prioritize cities for installing the solar-hydrogen power plant so that one candidate location was selected for each city. Different criteria including population, distance to main road, flood risk, wind speed, sunshine hours, air temperature, humidity, horizontal solar irradiation, dust, and land costare used for the analysis. From the analysis, it is found that among the candidates' cities, the site of Lalezar is ranked as the first priority for the solar-hydrogen system development. A measure of validity is obtained when results of the DEA method are compared with the results of the technique for ordering preference by similarity to ideal solution (TOPSIS). Applying TOPSIS model, it was found that city of Lalezar ranked first, and Rafsanjan gained last priority for installing the solar-hydrogen power plants. Cities of Baft, Sirjan, Kerman, Shahrbabak, Kahnouj, Shahdad, Bam, and Jiroft ranked second to ninth, respectively. The validity of the DEA model is compared with the results of TOPSIS and it is demonstrated that the two methods produced similar results. The solar-hydrogen power plant is considered for installation in the city of Lalezar. It is demonstrated that installation of the proposed solar-hydrogen system in Lalezar can lead to yearly yield of 129 ton-H2 which covers 4.3% of total annual energy demands of the city.

This study used GIS method for the characteristic analysis of farmstead location in study area. The present study surveyed the coordinates of location for 76 livestock farmsteads with big size in rural areas within city of Cheonan. Based on the surveyed data, this study analyzed the spatial characteristics of location for the farmsteads by using both new evaluation criteria and their corresponding GIS (geographic information system) layers developed in this research. The criteria consist of six factors, which are 2 geographic factors for slope(SLO) and aspect(ASP) of earth surface, 3 accessability factors for distance from water area(DWA), road(DRO), and built-up area(DBA), including type of landuse(TLA). In the analysis results of six criteria using the grid funcations of GIS, the highest distributed ratios of the farmsteads per criterion were found at the lower slope area less then 2% in SLO, the area with south and south-east direction in ASP, the area with distance between 500m and 1,000m in both DWA and DRO, the area within 500m in DWA, and the paddy and upland area in TLA. As new finding of this study, these analysis results seemed that the farmsteads have been located at the better places with the priority to build and manage conveniently and economically.

변전소와 같은 사회적으로 위험물로 인식되는 공공시설물에 대한 부지를 선정 할 경우에는 다른 어떤 시설물보다 부지 선정시 과학적이고 공정한 과정이 필요하다. 본 연구에서는 계층분석과정과 GIS의 공간분석 기능을 통하여 경기도 남부 지역의 변전소 선정에 요구되는 자료들을 축척 1/5,000 수치지도 및 현지 조사로부터 취득하여 최적의 위치를 안전성, 국가토지이용, 경제성 및 환경보전측면을 고려하여 선정하였다. 실제 처리과정에서 대상지역 전체에 대하여 1차적으로 반경 1.5km의 3개 지역에 대한 우선후보군을 선정하였고 선정된 후보군에 대하여 2차 현지 상세조사를 토대로 최종적으로 변전소가 건설될 4개의 후보 부지에 대한 다원 평가를 실시하였으며 정량적 분석을 통한 위치의 적정성에 대한 결론을 도출 하였다. 적지분석 결과 1후보 부지인 경기도 안성시 양성면 장서리 지역이 최적지로 나타났으며 다른 후보 부지들도 대체적으로 좋은 입지여건을 갖는 것으로 나타났다.

In this study, geomorphological and geological research has been carried out to estimate the possibility of ancient port location near Hwaseong Dangseong. Geomorphological characteristics around Eunsupo were analyzed through comparison of past and present topographic maps and field survey. Grain size, age dating, and geochemical analysis on surface sediments and borehole sediments were performed. Through the geomorphological characteristics analysis, it was interpreted that Eunsupo area was submerged in seawater especially at high tide in the past, and that ships could approach to the inside of the area through the tidal channel which were developed in the area. It is also assumed that ships were anchored at a low elevation point in the area. The paleo-environmental change in the area was analyzed based on the classification of sedimentary environment using grain size distribution of surface and borehole sediments and geochemical analysis. It was confirmed that the geomorphological interpretation for the possibility of ancient port location coincided well with the paleo-environmental change interpreted through sediment analysis. This study is a basic study for estimating ancient port location, and it is expected that more accurate paleo-environmental changes will be restored through detailed geomorphological survey and additional borehole analysis in the future research.

The buckling of the perforated web of a simply supported Η-section beam subjected to uniformly distributed load is examined by means of the finite element method. With buckling analysis results, the effect of this hole on the load carrying capacity of the beam with dimensions L/h = 11 and 13 ( L = span length h = web depth) is investigated. The parameters whose variation have been considered are hole size and location. It can be generally concluded that the buckling of the perforated web of an H-section beam is not affected seriously by the location of the perforation.

In case the fault occurs in AC power supply network, protective relaying system must selectively detect line-to-line/ground fault and immediately cut off the power flow into the fault location for guaranteeing the safety of people, electric vehicle and ground installation etc. It is the most important point in power system operation to minimize the fault duration by rapid trip scheme and accurate estimation of the fault location. In this paper, we analyze the load characteristics of each vehicle, perform the fault analysis of AC power supply network using AT current-ratio method. The result shows its usefulness.

5개 신도시내 초등학교별 장기(24년간) 학생수 증감추세를 9개 계획요소(개발밀도, 다양한 사설학원의 입지 가능 여부, 학교 위치, 통학구역 형태, 인근 학교와의 거리 공동통학구역 운영 여부, 보행자전용가로 조성, 접도조건, 통학로상 입체보차분리시설 유무 등)별 가설을 설정하고, 이를 바탕으로 장기 학생수 증감추세와의 연관성 판단기준에 따라 분석한 결과는 다음과 같다. 첫째, 개발밀도, 학교 위치, 통학구역 형태, 인근 학교 거리, 입체보차분리시설 설치 등의 계획요소는 뚜렷한 연관성이 뚜렷하게 나타났다. 둘째, 사설학원 입지와 인근학교 거리 보행자전용가로 설치의 계획요소는 약간의 연관성을 보였다. 셋째, 접도 차선수와 공동통학구역 계획요소는 연관성이 없었다. 본 연구는 수도권 1기 5개 신도시 89개 초등학교만을 조사 분석한 결과이기 때문에 이를 일반화하는데 한계가 있고, 분석요소 및 평가기준을 더욱 정교화할 필요가 있어 이에 대한 후속연구가 필요하다.
