In order to assess the present status of the fragmentation of ecosystem and the building of ecological corridor, 79 EISs(Environment Impact Statements) which were conducted in Kyunggido and Kangwondo have been reviewed using 36 analysing factor. The results obtained from this study were as follows: a. The most frequently appearing type of ecosystem fragmentation was 'mountain vs. mountain type in topography' and '2 vs. 2 grades in the degree of green naturality.' b. The most frequently listed fauna in EISs included squirrels and wild rabbits for mammals, grass snake and pit viper for reptiles, and tree frog and true tree frog for amphibians. c. Among the EISs for 50 projects, the construction of ecological corridor mentioned in only 4 projects and other structures such as drainage duct and closed conduit in 14 projects were suggested as ecological corridor. There were no corridors suggested in 32 projects. Thus, in case of using other structures for wildlife animals but ecological corridors, it should be accompanied by incidental facilities for including animal movement.

This research was undertaken to prove the relationship between street mall activation and architectural plan design. The research methodology was established based on the analysis of data of two existing street malls in Korea (Western Dome & LaFesta) and theoretical studies of outdoor space design. The findings from this study are the following: First, building blocks with segments in every 50m or so are ideal for detailed communication between visitors and building contents. Second, the ratio of width of main corridor and building height should be less than 1 to provide intimate feel and keep visitors' attention concentrated in the facility. Third, store unit should have more storefronts to be exposed more to passers-by and lead more pedestrian traffic. Fourth, shape of store unit would rather be wide and shallow, instead of narrow and deep, to have more exposure to the central corridor. Fifth, the building block of the busiest(most expensive) area that is usually at the main entrance area of street mall should be flexible to fit more smaller units to maximize the profitability. Sixth, the main entrance of store should face the main pedestrian corridor to induce the influx of visitors. Lastly seventh, anchor tenant that has strong name recognition is usually located on basement or higher level to induce pedestrian traffic into the mall, key tenants that are strong and familiar brand names should be located at the corner of building block with spacing to attract visitors, provide even distribution of traffic, and support wayfinding, and local tenant should be located at small units along the central corridor or remainder spaces occurred from building core layout.

K-UAM은 2035년까지의 성숙기 이후 상용화될 예정이다. UAM 회랑은 기존의 헬리콥터 회랑을 수직 분리하여 사용될 예정이기에 회량 사용량이 증가할 것으로 예상된다. 따라서 회랑을 모니터링하는 시스템도 필요하다. 최근 객체 검출 알고리즘이 크게 발전하였다. 객체 검출 알고리즘은 1단계 탐지와, 2단계 탐지 모델로 나뉜다. 실시간 객체 검출에 있어서 2단계 모델은 너무 느리기에 적합하지 않다. 기존 1단계 모델은 정확도에 문제가 있었지만, 버전 업그레이드를 통해 성능이 향상되었다. 1단계 모델 중 YOLO-V5는 모자이크 기법을 통한 소형 객체 검출 성능을 향상시킨 모델이다. 따라서 YOLO-V5는 넓은 회랑의 실시간 모니터링에 가장 적합하다고 판단된다. 본 논문에서는 YOLO-V5 알고리즘을 학습시켜 궁극적으로 회랑 모니터링 시스템에 대한 적합도를 분석한다.

In this study, the spatial analysis of the multi-housing unit plans was investigated since 1990 for the winners at the architectural competition which was held nationwide in Germany. The investigation was carried out from January in 1990 to December in 2010. 201Unit plans were analyzed. Space syntax model is used as analyzing tool of the Unit plans. The results of the study indicate followings: 1) The interior spaces in 3LDK types and 4LDK types, ordered by high value of integration are; (1) corridor, (2) entrance hall, (3) living room, (4) dining room. 2) The value of integration for the kitchen is higher in L/DK type than in LD/K type, and that for the living room is higher in LD/K type than in L/DK type. The mean value of integration for L/DK type is higher than that for LD/K type. This means that traffic line efficiency of L/DK type is higher than that of LD/K type. 3) The value of integration for corridor and entrance hall is gradually lower in recent years. That is, the type of Unit plans are changing from corridor types to hall types.

최근 산림청이 기후 변화 대응 대책으로써 지자체 바람길숲 조성 사업을 시행함에 따라 다양한 바람길에 대한 연구가 수행되어 오고 있다. 바람길숲 조성을 위해서는 바람길 기능에 대한 평가가 선행되어야 한다. 하지만, 현재 바람길을 직접적으로 평가하고, 바람길의 유형에 따라 공간을 구분할 평가 지표가 없어 간접적인 지표를 기준으로 분석을 수행하고 있다. 따라서 본 연구에서는 냉각에너지 분석을 찬공기 생성에 대한 평가 지표로 활용함으로써 바람길을 평가 및 분류하는 방법을 제안하였다. Kaltluftabflussmodell_21(KLAM_21)이라는 찬공기 분석 모형을 활용하여 냉각에너지 분석을 하였다. 그리고 시뮬레이션 분석 결과에 따라 바람길을 찬공기 생성지역, 찬공기 취약지역, 찬공기 유동지역으로 분류하였다. 냉각에너지량을 기준으로 상위 5퍼센트를 찬공기 생성지역, 하위 5퍼센트를 찬공기 취약지역으로 분류하였다. 또한 찬공기 유동지역은 찬공기 생성지역에서 이동하는 찬공기의 흐름을 파악하여 분류하였다. 분석 결과, 대구광역시의 바람길 6개의 바람 생성지역이 존재하며, 찬공기 취약지역은 시가지 내부에 집중되어 있었고, 찬공기 유동지역은 대구광역시의 주요 하천과 도로를 따라 형성되어 있었다. 본 연구의 방법론을 통해 바람길의 효과를 정량적 평가 방법으로 활용될 수 있을 것으로 기대된다. 또한 바람길숲 조성 사업지 선정에 제시할 수 있는 평가 지표로 활용될 것으로 판단된다.

Daejeon is a large city in Korea and very high-speedly developing city. Recently urban area is expanding and large forest patch is fragmenting into small habitats because of urban sprawl. The fragmentation of large forest patch decreases the size of habitats and increases the loss of biodiversity in urban area. This study is to analysis the connectivity of green space of Daejeon metropolitan city, and suggest the optimum location of greening site and corridor in order to increase the connectivity of green space of Daejeon metropolitan city. The findings of this study are as follows; (1) The result of this study showed that ${\alpha}$ and ${\gamma}$ index are -0.24 and 0.20. A ${\alpha}$ index is very low and a ${\gamma}$ index is relatively low. (2) The dispersion was very high, for urban forest patches were isolated through fragmentation. Therefore, it needed ecological corridors in order to connect the patches. (3) A urban streams were very important in connectivity of urban green space. Urban riparian corridor must be preserved and restored. (4) A urban green space policy and planning must be prepared to increase the connectivity and assessment of alternatives must be accomplished from perspective of connectivity. The results of this study show the practical implications in perspective of green space planning and policy in Daejeon metropolitan city. The suggestions by findings of this study are to connect green space between large forest patch in urban fringe and island green space in inner city. Also, It is required that urban stream is restored to natural feature for use of corridor by wildlife.

In this study the seismic risk assessments of six- and twelve-story staggered wall system structures with three different structural variations were performed. The performances of staggered wall structures with added columns along the central corridor and the structures with their first story walls replaced by beams and columns were compared with those of the regular staggered wall structures. To this end incremental dynamic analyses were carried out using twenty two pairs of earthquake records to obtain the failure probabilities for various intensity of seismic load. The seismic risk for each damage state was computed based on the fragility analysis results and the probability of occurrence of earthquake ground motions. According to the analysis results, it was observed that the structures with added columns along the central corridor showed lowest probability of failure and seismic risk. The structures with their first story walls replaced by beams and columns showed lowest margin for safety.

The purpose of this study was to provide basic information about design guidelines of activity areas in elderly nursing facilities. For the study, the activity areas of 44 facilities in Korea were investigated to categorize their spatial compositions and forms, and then a case study about 19 facilities was conducted to analyse their hierarchical characteristics. The results of the study were as follows: First, the major type of spatial composition among 44 research facilities was concentration, but compartment type was the main among unit-care facilities. By the year, all the types of spatial composition were evenly distributed during recent five years, while concentration type was about 40% before 2003. Second, the major form of activity areas was hall or corridor extension for large group. But there was more alcove or separation form among small group spaces. Third, in the case analysis about hierarchical characteristics, hall and corridor extension form met the requirements of accessibility and openness of public and semi-public areas. On the other hand, separation form had a problem in satisfying both requirements. The semi-private areas, which were around the elderly bedrooms and the elderly were able to watch activities in, were not sufficient in many facilities. Fourth, the division of public and semi-public area was mainly by furniture, and the individuality of semi-private area was defined by dead-end place and corner seats of the window or the corridor. The diversity of semi-private area was likely to be appeared in connection or distribution type. On the basis of the results, the basic design guidelines for activity areas in elderly nursing facilities could be suggested as follows: On the whole, connection or distribution type in spatial composition is more efficient for hierarchical flow than concentration or compartment type is, especially in Korean facilities having many elderly residents per floor. In detail, the design of public and semi-public area should be focused on their openness and accessibility. The recommended forms of activity areas were hall or corridor extension in public area, and living room, corridor extension, or large corridor in semi-public area to effectively function as large or small group spaces. In semi-private areas, the spatial diversity and individuality should be considered.

본 연구는 찬공기 특성을 유역단위로 분석하고, 유역 내 생성되는 찬공기를 도시 바람길 계획에서 활용하는 방안을 제안하는 것을 목적으로 한다. 이를 위해, 경기도 지역의 북쪽에 위치한 중랑천 유역의 의정부시, 남쪽에 위치한 안양천 유역 및 양재천 탄천 유역의 과천시를 연구 대상지로 선정하였다. 찬공기 특성 분석을 위해 독일에서 개발된 모형인 KALM(Kaltluftabflussmodell)을 활용하였으며, 야간 6시간 동안 생성되는 찬공기 흐름 및 찬공기층 높이를 파악하였다. 중랑천 유역의 주요 바람길이 흐르는 곳에 위치해 있는 의정부시는 남쪽 외곽에서부터 유입된 찬공기가 의정부시 전체 바람길 계획의 중요한 부분을 차지하고 있다. 또한, 서쪽의 사패산 일대에서 생성된 찬공기는 시청 인근의 중심상업지구까지 유입되고 있어 도심의 열환경을 조절하는 주요한 역할을 수행하는 것으로 판단된다. 반면, 의정부시 동쪽지역은 바람길 이용이 원활하지 않는 것으로 파악되었다. 동쪽의 관악산과 서쪽의 청계산 등에서 생성된 찬공기 흐름은 과천시의 북쪽 지역에서 가장 활발하였는데, 이 흐름은 안양천 및 양재천 탄천 유역 전체에서도 주요한 바람길이다. 이에 비해, 찬공기 흐름이 원활하지 않은 남쪽지역에 '과천지식정보타운 공공주택지구' 조성이 계획되어 있어 향후 이 지역의 주거환경이 저하될 가능성이 크다. 향후, 이 지역을 개발할 경우 상세한 바람길 분석을 통한 바람길 활용 계획을 추가적으로 수립할 것을 제안하였다.
