  • 수자원 개발에 있어 중요한 문제 중의 하나는 개발가능지의 선택과 후보지가 복수일 때 개발 우선순위를 결정하는 것이라 할 수 있다. 이러한 문제 해결을 위하여 적지분석을 실시한다. 적지분석 과정은 크게 기초 조사 및 자료수집, 예비후보지의 선정, 대안평가, 입지선정의 :t단계로 구분되는데 여기서 2-3단계인 예비후보지 선정과 대안평가 단계가 적지분석 기법이 적용되어야 할 과정이다. 기존의 의사결정 방법론들은 각 대안의 우선순위를 위해 각 항목들에 대한 가중치나 확률치를 이용한 수치적 계산에 의한 방법들이 대부분이며, 또한, 각 후보지에 대해서 동일한 항목에 대한 정보를 요구하게 되어 한 후보지이라도 정보가 없는 경우 우선순위를 위한 계산과정에서 제외하거나 결정자의 경험 등에 의한 추정 값을 사용할 수밖에 없다. 이러한 이유로 본 연구에서는 입지선정에서 대상 후보지의 인자비교를 위한 항목의 자료 유무에 관계없이 적지분석이 가능하도록 게임이론을 적용하여 수자원 개발 가능 후보지를 도출하기 위한 기본모형을 개발하였다.

  • EMC 안테나의 트성평가용으로 사용할 안테나 시험장의 적합성을 평가하기 위한 반파장 공진 다이폴안테나를 설계하고, 안테나의 치수변화가 안테나 인자에 미치는 영향에 대하여 고찰하였다. 그 결과, 안테나의 길이 및 반경이 $\pm$1/mm/정도 변화하더라도 안테나 인자에는 큰 영향을 미치지 않는다는 것을 확인할 수 있었다. 또한, 설계이론의 타당성을 확인하기 위하여 실험결과와도 비교하였다.

  • This paper deal with the stability evaluation and suggestion of progressive failure slope in biotite granite area of Andong. Based on geological site investigation and field test, stability analysis of slope was performed in conjunction with limit equilibrium methods and stereographic projection. Additionally, initial design and construction procedure was critically evaluated. Series of the slope stability analysis reveals the detection of local wedge and plane failure under the current slope condition. It is additionally appeared that a certain synthetic behavior of circle and plane failure exists on the right spot where the overall failure's going in progress. In order to construct more stable slope based on the suitability for the real state of the slope circumstances, this study issues a solution to eliminate the primary factors which cause the instability, by means of the grade of weathering and RMR classification of rock mass.

  • We have studied the prearranged plan and the economy of a candidate site for the development of small hydro power. And also we have confirmed its economy by suggesting the technology of the unmanned operation and the selection of the water turbine generator which has a great efficiency, working rate and suitability to the topographical characteristics of various development sites, for example, irrigation reservoirs, water works pipes, sewage systems and cooling water of a steam power station. We proposed some opinions such as the better improvement of small hydropower industry the people' view, cooperation among industry/university/ research institutes, remote control/maintenance and goverment's legislature and supporting system etc.

  • Geophysical surveys (electrical resistivity, self-potential, and magnetic methods) and streamwater sample analysis have been carried out at a site of tailings of waste deposits in an abandoned mine, Jangpoong, which is situated in Kowesan-Gun, Chungbuk-Do. The research was aimed at investigating the suitability of the various geophysical methods for detection of AMD (acid mine drainage) paths, and ultimately mapping of preferred AMD flow channels by incorporating the water sample analysis. Electrical resistivity section from the dipole-dipole line represents the low-resistivity zone trending northwest toward the stream nearby. The positions of the resistivity anomalies for AMD channels are well correlated to the ones from the various geophysical surveys. In addition they correspond to the sites of the higher peaks for the pH, EC, heavy metal content for the water sample data.

  • This paper summarizes the results of a two-year-long research project conducted by the CTBUH on the life cycle assessment (LCA) of tall building structural systems. The research project was made possible thanks to a $300,000 contribution from ArcelorMittal and the support of some of the most important structural engineering firms and players in the tall building industry. The research analyzed all life phases of a tall building's structural system: the extraction and production of its materials, transportation to the site, construction operations, final demolition of the building, and the end-of-life of the materials. The impact of the building structure during the operational phase (i.e., impact on daily energy consumption, maintenance, and suitability to changes) was also investigated, but no significant impacts were identified during this phase.

  • To build environmentally friendly highways, we testes suitability for unique characteristics of pollution mitigation facility around the highways by evaluating optimal selections and implementation methodologies to minimize loan of non-point pollution substances into water-ways. To do this we categorized EIA target highways into three types ; big drainage basin, small drainage basin, and bridge section as to minimize non-point pollution of highway runoff. The terms of selected facility test based on the Natural and Manufactured Treatment Device were removal efficiency of TSS, BOD, COD, T-N, T-P, compatibility of site selection, economic feasibility, maintenance convenience, and the final mitigation facility.

  • Corticosteroids have been used most frequently for inflammatory bowel disease.They are well absorbed and only a limited fraction of the dose is delivered to the inflammatory site in the colon. To reduce side effects by the systemic absorption. cOlon-specific delivery is highly desirable. We prepared prednisolone 21-sulfate sodium (PDS) and investigated its suitability as a colon-specific prodrug of prednisolone(PD). (omitted)

  • In a previous study, the suitability for use of inspection equipment was evaluated at temperatures outside the quality assurance range. The quality assurance operating temperature of the safeguards equipment is 0~+40℃, and previous studies have confirmed the performance of the safeguards equipment for temperatures ranging from -40~+70℃. The scintillator-based verification equipment showed a shift in the centroid channel and a change in the count rate in all temperature ranges, and the semiconductor-based safeguards equipment generated Leakage Current and equipment failure. In this study, a retrofit was performed applying a vacuum housing to the safeguards equipment (Inspector-2000-based inspection equipment), and performance evaluation was performed at a low temperature and snowy site, and it was confirmed that the same performance was observed as the measurement results at room temperature.

  • Pungsu theory is important one in the site selection and lay-out of traditional Korean village and house. In this aspect, Study with a view of Pungsu theory might be used as a proper method for understanding the traditional architecture in Korea. In this context, this study analyzes the Jeong, Dong-Ho's house which is designated no. 19 as an important folk cultural heritage, located in Jigok Ochu-gil 133-62, Godeok-myon, Yesan-gun, Chungnam province. The analysis of the site and space lay-out is carried out by Yong(Dragon), Hyoel(Auspicious Spot), Sa(Sands), Su(Water) aspects of the Pungsu(Fengshui) Hyungsei-ron. The house is depending upon soft dragon vein connecting with a earth type rear mountain. It looks southeast direction, Gonjwasonhyang(乾坐巽向). The hyeolseong(穴星) has classical venus shape, and there is no faults relatively. The Sasinsa condition is almost perfect that right blue dragon and left white tiger surround the hyeol with 3-4 layers and the facing mountain covers the front open area. The water flowing from inside of left and right mountain is joined in front of the house so it could stop flowing out of vital energy. Bibo forest(裨補樹) is placed properly to protect the easy disclose of water outlet. The house is well organized western house(西四宅) by analysis of Dongseosataek-ron(東西四宅論). Through the analysis, I found that the house has good Pungsu(Fengshui) environment fitted with Pungsu Hyungsei-ron. The house composed of small thatched roof is enclosed several times by low hills of back, left and right side. So it is believed that the site might be carefully evaluated by Yong, Hyoel, Sa, Su of Hyeongsei-ron for knowing whether the site condition could minimize the demage by strong winds and protect from the winter cold wind and secure water for drinking and farming and then selected. The method of Pungsu for evaluating the geographical condition of surrounding of a site is used as a traditional site analysis method for evaluating the suitability of long-term well and safe residence.
