The urgent VAI method development is required since "The Act of Physical Protection and Radiological Emergency that is established in 2003" requires an evaluation of physical threats in nuclear facilities and an establishment of physical protection in Korea. The VAI methodology is developed to (1) make a sabotage model by reusing existing fire/flooding/pipe break PSA models, (2) calculate MCSs and TEPSs, (3) select the most cost-effective TEPS among many TEPSs, (4) determine the compartments in a selected TEPS as vital areas, and (5) provide protection measures to the vital areas. The developed VAI methodology contains four steps, (1) collecting the internal level 1 PSA model and information, (2) developing the fire/flood/pipe rupture model based on level 1 PSA model, (3) integrating the fire/flood/pipe rupture model into the sabotage model by JSTAR, and (4) calculating MCSs and TEPS. The VAT process is performed through the VIPEX that was developed in KAERI. This methodology serves as a guide to develop a sabotage model by using existing internal and external PSA models. When this methodology is used to identify the vital areas, it provides the most cost-effective method to save the VAI and physical protection costs.

건설 산업의 재해 중 상당 부분은 작업자의 이동 중 발생한다. 건설 현장의 안전관리는 작업을 중심으로 수행되며, 이는 이동 경로에 존재하는 위험원에 대한 안전관리 수준을 상대적으로 낮게 만든다. 많은 연구자들이 위험원을 인지하는 것이 안전관리의 기본임을 제시하였다. 따라서 본 연구에서는 자동화 데이터 수집기술(Automated Data Collection)을 이용하여 작업자의 이동경로에 존재하는 위험원에 대한 안전관리자의 인지를 지원하는 모델을 개발하였다. 모델은 실시간 위치추적기술 기반의 작업자의 위치정보와 BIM을 통한 최적이동 동선의 비교를 통해 일차적으로 위험 가능 지역을 찾는다. 그리고 기존 위험지역과 작업지역을 필터링함으로써 위험 가능 지역을 폭을 좁힌다. 이를 바탕으로 안전 관리자는 위험원이 존재할 가능성이 높은 지역에 대한 정보를 제공받고, 현장의 상황에 맞는 안전관리대책을 수립할 수 있을 것이다. 본 연구에서 제시된 모델을 통해 발견하지 못한 채 남을 수 있는 위험지역을 인지함으로써 안전관리 프로세스 범위에 속하지 않는 위험원을 줄일 수 있으며, 이를 통해 건설 현장의 안전 향상에 도움을 줄 것이라 예상된다.

Objectives: The aims of this study were to examine the level of airborne fungi and environmental factors in Seoul metropolitan subway stations and to provide fundamental data to protect the health of subway workers and passengers. Methods: The field survey was performed from November in 2004 to February in 2005. A total 22 subway stations located at Seoul subway lines 1-4 were randomly selected. The measurement points were subway workers' activity areas (station office, bedroom, ticket office and driver's seat) and the passengers' activity areas (station precincts, inside train and platform). Air sampling for collecting airborne fungi was carried out using a one-stage cascade impactor. The PM and CO2 were measured using an electronic direct recorder and detecting tube, respectively. Results: In the activity areas of the subway workers and passengers, the mean concentrations of airborne fungi were relatively higher in the workers' bedroom and station precinct whereas the concentration of particulate matter, $PM_{10}\;and\;PM_{2.5}$, were relatively higher in the platform, inside the train and driver's seat than in the other activity areas. There was no significant difference in the concentration of airborne fungi between the underground and ground activity areas of the subway. The mean $PM_{10}\;and\;PM_{2.5}$ concentration in the platform located at underground was significantly higher than that of the ground (p<0.05). Conclusions: The levels of airborne fungi in the Seoul subway line 1-4 were not serious enough to cause respiratory disease in subway workers and passengers. This indicates that there is little correlation between airborne fungi and particulate matter.

본 연구는 코로나19의 확산을 기점으로 농어촌 정보화에 대한 긍정적/부정적 인식과 연관 키워드가 어떻게 변화하였는지를 분석하고, 이를 통하여 농어촌 지역에 대해 외부에서 인식하는 IT Savvy 수준을 간접적으로 이해하고자 빅데이터 분석을 수행하였다. 농어촌 정보화와의 관련 키워드로 코로나19 이후 농촌 지역 학생들의 대입이나 교육과 같이 비대면으로 인한 악영향을 최소화하고, 비대면 상황에서 경제적, 사회적인 약점을 완화하기 위한 정책을 우선 추진하고 있음을 알 수 있다. 또한, 농어촌 지역의 정보화와 관련된 키워드의 감성 분석 결과, 농어촌 정보화의 IT Savvy 성과, 즉 농어촌 지역의 디지털 격차 감소, IT활용 역량 개선 등에 대한 외부 인식은 긍정적인 것으로 나타났다. 이것은 정보화 관련 정책이 코로나19 확산에 긍정적으로 대응한 것으로 인식하는 것임을 보여준다. 본 연구는 코로나19와 농어촌 정보화라는 키워드를 중심으로 분석하였다는 희소성을 가지고 있다. 그러나, 농어촌 거주민을 대상으로 하는 직접 조사 자료를 확보하기 어려운 시점이기 때문에 데이터의 수집과 분석에게 한계가 있었으며, 이러한 한계에 따라 불가피하게 빅데이터 툴을 활용한 기초적 연구를 수행할 수 밖에 없다. 향후에는 이러한 한계를 개선하고 다각적인 학제 연구를 수행할 필요가 있다.

Activities in the dwelling are inseparable from housing design. Spatial features often result from patterns of activities that take place within the dwelling. Activities are further elaborated to affect house plans, furniture, arrangement, and equipment. However, discrepancies still exist between housing design and behavior, where housing design often fails to accommodate activities and behavioral dimensions within the family and the dwelling. This paper addresses the relationship between dwelling activities and housing design by means of a qualitative study that aims to understand the needs of the Indonesian dwelling through activity analysis. To do so, the research adopts a methodology that involves collecting data from measurements of the house, house plan analysis, and photographs, in addition to in-depth semi-structured interviews with families. Taking Bandung as a case study, 9 houses and families were selected as respondents that share similar family life-cycles, number of family members, and building size. The findings from the study suggest that spacious and open plans are preferred by the family, while maintaining family privacy. Guest areas are used to host formal guests and to restrict visitor access in the house. Service areas such as kitchens and laundry areas are the core areas for household activities for cooking, laundry, and drying. To meet social activities such as community gathering, open plan design is necessary to allow flexibility of furniture reconfiguration to accommodate extra guests.

The LRA(Logistic Regression Analysis) conducts a quantitative analysis by collecting a lot of samples and the AHP(Analytic Hierarchy Program) makes use of expert decision influenced by subjective judgment to a certain degree. This study is to suggest a combination method in mapping landslide hazard by giving equal weight for the result of LRA and AHP. Topographic factors(slope, aspect, elevation), soil dram, soil depth and land use were adopted to classify landslide hazard areas. The three methods(LRA, AHP, the combined approach) was applied to a $520km^2$ region located in the middle of South Korea which have occurred 39 landslides during 1999 and 2003. The suggested method showed 58.9% matching rate for the real landslide sites comparing with the classified areas of high-risk landslide While LRA and AHP Showed 46.1% and 48.7% matching rates respectively. Further studies are recommended to find the optimal combining weight of LRA and AHP with more landslide data.
