The paper analyzed the excavational data from Bupyeong-office in Ulsan county in Chosun Dynasty, examined the composition of the community estimated at station community, and studied the duration of the community by using the excavated relics. In addition, the paper compared the excavational data with documentary records, studied the location Bupyeong-office, and investigated the size of station community overall. Community compositions such as buildings, residential place, pits, stoves, hemp kilns, cremation tombs, and farming appliances were identified. When compared to excavated relics such as tiles, white porcelain jars, agrayish-blue-powdered celadons, and celadon porcelains from building, residance, and pits, the community existed during 14C~17C. The station location was on the west side to the quarters for Byongmajuldosa of the Left Gyeongsangdo at King's location according to the old maps and documentary records. It is widely expected that No, 201 foundation stone buildings at Pyungsan relic I was related to the station because there was a distinctions on the stone pillar waterway and high quality of location in the size(the front 9 sections ${\times}$ the side 1 section) and the community. According to the building's functions and duplication relations in the community, it is regarded that there were 33~40 ground buildings, 40~45 pitting buildings, storages or 15~30 other purpose buildings, and 5~7 public buildings around No, 210 building in Bupyeong-office town.

In Space Syntax, the greater the degree of integration between separate links, the greater the links' accessibility from the target network. As such, planning pedestrian walks so that links with high degrees of integration are connected, or else inducing high integration value land use are both valid options. The travel distribution model reflects how walking demand, or more specifically, the pedestrian, partakes in route choosing behavior that minimizes select criteria, notably level of discomfort, as measured using travel distance and time. The model thus demonstrates travel patterns associated with demand pertaining to minimization of discomfort experienced by the pedestrian. This research introduces a method that integrates Space Syntax and the pedestrian travel distribution model. The integrated model will determine whether regions with high degrees of integration are actually being used as pivots for pedestrian demand movement, as well as to explain whether the degree of integration is sustained at an appropriate level while considering actual movement demand. As a means to develop the integrated model, a method that combines display of the visibility of the space syntax network and road-divided links is proposed. The pedestrian travel distribution model also includes an alternative path finding mechanism between origin and destination, which allows for uniform allocation of demand.

Asbestos is composed of long thin fibers approximately diameter $0.02\mu\textrm{m}$ and flexibility, strength, electrical, thermal conditions. The most common asbestos are : Chrysotile(white), Crocidolite(Blue), Amosite(Brown). Asbestos was first introduced in the Korea in 1960 and installation of these products continue through the late 1970's and even the early 1980's. Bu-pyung basement stores in Korea were surveyed from September 25 to October 26, 2001. The purpose of this research was to evaluate worker-exposure to asbestos, comparing to the standards and to research notice of inhabitants about asbestos. Fifteen personal samples and six areas were collected using Gillian Air Sampler. Result of this research were as follows. 1. The most of asbestos exposure concentrations keeps to the criterion(OSHA(Occupational Safety and Health Adminisoation), NIOSH) but forty three percent of the Six samples exceeded the EPA (Environmental protection Agency) of 0.01 fibers/cc. 2. All of places compliced to the standards but there is no "Safe level" of asbestos exposure to the people. Especially people who are expose more frequently over a long time are more at risk.

도시지역의 내수침수피해는 거의 매년 발생하고 있으며, 반지하와 같은 거주공간이 매우 취약한 상태이다. 특히 최근에는 지하철, 지하상가 등이 대규모 개발되고 복합네트워크화 되어 지하공간의 침수대책과 대피방안 마련이 시급한 상황이다. 일본의 경우 2000년 토카이 호우피해 후 통합유출해석 모형을 개발하였으며, 1999년 및 2003년 후쿠오카 침수피해 발생 후 특정도시하천침수피해대책법을 제정, 1999 후쿠오카, 2004년 하마마츠, 2008년 카누마 피해 후 일본 방재연구소에서는 실시간 1차원 지표범람모형과 모니터링을 통한 실시간 내수침수지도를 개발하였다. 특히 지하공간에 대해서는 "지하공간에 유입하는 범람수가 계단상 보행자게에 주는 위험성에 관한 연구" 등 실험을 바탕으로 각종 지하공간 침수대책 매뉴얼 및 지하시설의 침수시 피난확보계획 지침, 지하공간 침수대책 가이드라인 등 인명피해를 줄이고자하는 노력이 계속되어 오고 있다. 우리나라는 2006년 경기도 고양시 3호선 정발산역이 침수되었으며, 2010년 서울시 지하철 2호선 사당역 및 4호선이 침수되는 등의 지하철 침수피해와 2010년 서울시 광화문 지하상가, 인천시 부평구 우림라이온스 벨리, 우남플라자, 계양구 농협하나로마트, 서원아파트 등의 지하상가와 지하다층의 침수피해가 발생하였다. 특히 2006년 3호선 정발산역 침수는 17시간이나 지하철이 불통되었고 이로 인하여 심각한 교통 체증이 유발 되었다. 본 연구에서는 2010년 집중호우로 인한 서울, 인천지역의 지하공간 침수피해를 중심으로 최근 10년간 지하공간 침수피해사례로부터 대표적인 침수피해 원인 및 특성을 정리하였으며, 그 결과 지하공간 침수의 주요원인은 지상공간의 침수류가 지하공간으로 유입하고, 지하공간의 배수설비 용량부족, 지하공간으로의 유입을 방지하기위한 방지턱, 차수판, 침수시 비상전원 공급, 침수시 지하공간 대피 매뉴얼의 부재 등 다양한 원인이 있는 것으로 나타났다. 특히, 소방방재청에서 고시한 '지하공간 침수방지를 위한 수방기준'에 지하공간 침수 방지를 위한 각종 시설의 설치 및 대피 경로지정 등에 대한 기준이 마련되어 있으나, 지하공간 중 유동인구가 가장 많은 지하철역에서 조차 침수에 대한 행동매뉴얼이나 대피에 대한 가이드라인이 마련되지 않은 것으로 나타났다. 따라서, 지하공간 침수를 방지하기 위하여 센서를 이용한 자동 차수판과 경보기 설치, 지하공간의 사람들이 안전한 대피로를 찾을 수 있도록 지상공간 및 지하공간 출입구를 모니터링 할 수 있는 CCTV의 설치, Dry Area를 두어 비상대피 할 수 있는 공간의 마련 등 시설적인 부분에 대하여 '지하공간 침수방지를 위한 수방기준'을 더욱 강화할 필요가 있으며, 지상공간의 침수 상황을 고려한 지하공간의 대피매뉴얼 또는 가이드라인 등의 수립이 필요하다. 또한 이와 더불어 재산 및 인명피해를 더욱 효율적으로 줄일 수 있도록 실시간 예 경보를 위한 침수해석 모형의 개발이 시급하다.

Most student misconceptions about evolution are similar to misconceptions and disputes which early scientists had in science history. The aim of this study was to analyze student evolution conceptions based on science history, there by revealing for effectively teaching strategies on evolution. A test was developed according to Lee's three dimensional framework (2004) on evolution concept changes. Lee's framework had been constructed according to 4 stages of evolution concept changes in history in three-dimensional aspects such as mechanism, time, and subject: before Lamarck (stage 1), Lamarck (stage 2), Darwin (stage 3), and after Darwin (stage 4). Major results were as follows. First, the evolution conceptions of students appeared fixed to stage 2 regardless of grade. Moreover, students usually possessed Lamarckian thought and did not show consistency in evolution concepts among the three dimensional aspects of mechanism, time, and subject. Therefore, students were found to apply different conceptions of evolution to each different situation.
