The purpose of this study is to analysis the change of rural house type and house plans in Bonghwa province. According to definition of rural area, the scopes of the research of rural houses limited the Bonghwa rural area(1 eup, 9 myeon). The method of study is to compare and analyze about housing situation, structure of house, housing type and construction of house space etc. through the statistical data of Bongwha statistical yearbook, space syntax(convex analysis) and other various data etc. during these 10 years. As a results of the analysis 1) According to Change of family member the supply ratio of detached house is steadily decreasing and changing from a detached house to multi-household house in Bongwha areas. 2) Most of houses structure were using lightweight steel construction because of cost-cutting of construction and easy way to construct etc.. 3) The highest Integration space is living space in rural house plans 4) The highest segregation space is bathroom space of master bed room in rural house plans. Some of bed rooms are classed as segregation space regardless of Integration space 5) Traditional front yard's function is changing from the place with the various functions to the place with the specific functions.

According to the 2007 Korea library yearbook, 162 out of 589 special libraries are one person libraries which means an individual librarian takes responsibilities of all librarian tasks. Due to its particularity and diversity, however, there is lack of research on special libraries compared to the other libraries and no job analysis for human resources to be effectively managed has been done. This study aims to understand the current status of one person library by investigating its tasks and frequency, importance, difficulty of its duties. This study also suggests plans to improve the job by analyzing its association with affiliated organizations of one person library.

Due to the eccentricity of the Earth's orbit around the Sun and the obliquity of the Earth rotation axis against ecliptic frame, the apparent solar time differs from the mean solar time. Since the solar array of a GEO satellite makes a turn in mean solar day, the Sun pointing error of solar array is introduced over the year due to the equation of time. In this paper, efficient methods of compensating the equation of time to keep the solar array pointing the Sun are presented and verified with realistic simulation.

In this study, a smoke or a heat which occurs by a fire is perceived by wireless detector, this signal is transmitted to the receiving device by the wireless installation which is not the wire device and wire/wireless integration system which sends this signal to main server via wire system is proposed. In addition wireless heat/smoke detector, wireless module, firmware and wire/wireless integration controller were developed and for verifying regarding the efficiency and applicability of wire/wireless installation actual place application experiment was really accomplished with a transmission tower, a multipurpose building, and a station etc of the subway. The experimental result, it could operate the system which is proposed normally with all experimental object ones and, future actual place application possibility could verify.

발전이란 말은 한 국가나 사회가 교육적, 경제적, 사회문화적 및 정치적으로 안정된 기조를 확립하여 국민 전체가 생을 영위함에 있어서 경제적으로 부족함이 없이 윤택하고 각종 사회적 제도가 참 삶을 추구할 수 있는 방향으로 변천되어 가는 과정을 뜻한다. 본 연구는 발전과 번영을 위해 약진하고 있는 대한민국의 최근 20년간의 발전과정 (1950년부터 1970년까지)을 경제적측면과 교육적 측면에서 미국의 것과를 비교하기 위하여 유네스코 통계 연감에 의하여 그 자료를 분석 검토하였다. 본 연구에서 한국은 경제성장율이 늘어남에 따라서 교육비 투자가 증가되었고 따라서 초등교육과정은 1965년도에서부터 취학율이 100%를 상회하게 되었으나 중등교육은 1968년도에 취학율이 겨우 36%로 아직도 저조하며 여학생 취학율은 초등교육에서 는 남녀 의 차이 가 없으나 중등교육에서는 1/3선으로 떨어지고 있으며 특히 여선생님의 남선생님에 대한 비율은 중등교육과정에서 걱우 14%밖에 안되고 인구 10만당 대학졸업생수는 1968년을 기준으로 볼 때 계속 증가되어 왔으나 미국이 3,735명(그중 40%는 여학생임)인데 비하여 한국은 566명 (여학생은 26%)으로 고등교육의 혜택을 받는 율이 아직도 미국에 비해서 낮고 초등교육과정에서 학생과 선생님의 비율을 보면은 한국은 60 : 1 인데 비하여 미국은 26 : 1로써 미국보다 높고 따라서 한국은 교직원 부족과 시설미비, 농촌과 도시간의 차이 및 고등교육 혜택의 불균형 및 여성교육의 기회가 남성에 비해 낮고 해외 유학의 경우 본국 귀환율이 적어서 지도자 양성이 문제되고 있다. 그러나 한국은 1960년대에 급격한 경제성장과 함께 교육투자도 증가되었고 따라서 발전을 거듭하여 계속하고 있다.

최근 기상이변의 가속화로 인해 홍수피해는 더욱 증가되고 있으며, 도시화로 인해 불투수면적이 급격히 늘어남에 따라 기존 관개수로의 통수능력 부족으로 도시침수피해가 증가되고 있다. 재난 연감과 재해연보를 바탕으로 비교한 결과, 홍수를 비롯한 각종 재난 발생 시 일반적으로 남성들에 비해 여성들의 피해자 수가 많으며 피해의 정도는 상대적으로 심각하였다. 그러나 국내외적으로 홍수에 대한 피해를 줄이고자 홍수 취약성에 대한 많은 연구들이 수행되었지만 아직 젠더를 고려한 취약성 분석은 부족한 실정이다. 본 연구에서는 대상지역을 우리나라의 인구밀집도가 가장 높은 서울시 25개구로 선정하였고, 엔트로피 이론을 활용해 25개 구의 홍수 취약성 지수를 계산하였다. 홍수 취약성 지수 계산 시 고려요인으로는 여성인구비율, 고령화비율 및 인구밀도 등과 같은 사회적 요인과 연 홍수 피해액, 복구금액 등 경제적 요인 그리고 일일 최대 강수량 및 80mm 이상의 강수량, 홍수 피해 횟수 등과 같은 환경적 요인을 고려하였다. 그 결과 각각의 요인에 따라서 서울시 25개구의 홍수취약성 지수가 상이하게 나타나는 것을 확인할 수 있었다. 이를 통해 취약성지수가 높은 자치구들의 경우 지역특성을 고려한 별도의 홍수대책 가이드라인이 필요 할 것으로 판단된다. 본 연구의 결과물을 바탕으로 향후 홍수 대책이나, 홍수대비 관련 정책을 수립할 정부 및 지자체에서 사회, 경제, 환경적 요인을 고려한 합리적인 정책 수립 결정에 도움이 될 것으로 판단된다.

Recently, we can find news about toxic and combustible gas accident. So, we have to develop gas detector that can measure gas at dangerous area for preventing gas accidents. In this paper, we calculate a approximation function from sensor's output using the linear regressiong. And we develop software algorithm using Neville's algorithm for measuring gas concentration. Finally, we compare our algorithm with combustible gas detectors that are already developed, by using standard gas samples manufactured Korea Gas Safety. As a result of this experiment, we confirm that performance of our algorithm is more improved than performance of already developed combustible gas detectors. In the future, we'll research how to improve reliability from using count, temperature and humidity. And we'll design hardware applied explosion proof for safety.

According to the disaster statistics issued by the Ministry of Public Safety and Security, traffic accidents, fire, collapses and others are classified into twenty-three (23) categories. In the past, disasters were mainly caused by the influence of nature, such as typhoon or drought. On the other hand, as society has become city-centered, social disasters' types, frequencies and scales are becoming more diversified and ever-increasing. However, there are no specific criteria and assessment methods that can measure degrees of social disasters-related risks objectively. Therefore, this study targeted traffic accidents, fire and collapses from major social disasters, utilized data that are related to occurrence rate, scale of casualties and scale of property loss in past eight years, and calculated the disaster risk index using the distance (Euclidean distance) between two points on the 3D spatial coordinates, in order to make the objective assessment by social disaster type possible. These results will enable the objective evaluation of risk index of major social disaster to be used as the foundational data when building the national disaster management system.

This study was investigated on the effect of degumming of cocoon shell, raw silk yarn and grey silk crepe by use of Papain, comparing with soap, soda and soap-soda. The obtained results may be summarized as follows : 1. Degumming loss, when the pretreatment was done, was completed by Papain more than by alkali. 2. Lousiness result of Papain degummed silk yarn was apt to be improved more than that of alkali degummed one. 3. As a result of tensile property test, elasticity and resilience of Papain degummed crepe were good compared to those of alkali degummed one. 4. Not only bending rigidity of Papain degummed crepe was reduced more than that of alkali degummed one but also hysteresis of bending moment was decreased in papain degummed crepe. 5. Handle of Papain degummed crepe was superior to that of alkali degummed one.

Antheraea pernyi silkworm is one of typical wild silkworms, which spins a tawny color cocoon. The cocoon has been used as a resource for textile material due to strong chemical stability and good mechanical properties. In this study, to increase the solubility efficiency of A. pernyi silk fibroin, the composition of dissolution solvent were examined. Calcium chloride tertiary system, normally used for dissolution of Bombyx mori silk fibroin, does not act on A. pernyi silk fibroin. Calcium nitrate system dissolves A. pernyi silk fibroin, and calcium nitrate ethanol system do more easily than calcium nitrate system. Amino acid composition of A. pernyi silk fibroin obtained after dissolution is mainly composed of alanine, glycine, and serine. A. pernyi silk fibroin would be used for non-textile applications near future.
