최근 스마트폰 보급과 측위 기술의 향상으로 보행자용 내비게이션 서비스(Pedestrian Navigation Service, PNS)에 대한 관심이 높아지고 있으며, 보행자의 이동 특성과 길 찾기 성공률 측면에서 보행자에게 길안내를 하는데 랜드마크를 이용하는 것이 효율적이다. 이에 PNS를 위하여 랜드마크를 추출하려는 연구들이 진행되어 왔다. 그러나 이들 선행연구는 랜드마크를 추출할 때 건물들 간의 차이만을 고려하고, PNS가 구동되는 화면 속 지도에 대한 사용자의 시각적 주의를 고려하지 않았다는 한계를 가지고 있다. 본 연구는 건물의 속성을 지역적 변수와 전역적 변수로 정의함으로써 이와 같은 문제를 개선하고자 한다. 지역적 변수는 건물들 간의 차이를 나타내고 전역적 변수는 건물이 가지는 고유한 특성을 나타냄으로써 건물의 현출성과 시각적 주의 정도를 반영한다. 또한, 네트워크 보로노이 다이어그램을 이용하여 네트워크의 연결성을 고려하고 랜드마크 후보군 추출 시 발생하는 중첩 현상을 해결한다. PNS를 위한 랜드마크를 추출하기 위하여 선행 연구를 바탕을 건물 속성정보를 정의하였다. 다음으로, 보행자를 위한 선택점을 선정하고, 해당 선택점 별로 랜드마크 후보군을 추출하였다. 이들 랜드마크 후보군에 대해서 정의된 건물 속성정보를 산출하고, 주성분 분석을 이용하여 랜드마크를 추출하였다. 제안된 기법을 서울특별시 관악구 일부 지역을 대상으로 적용하여 랜드마크를 추출하고, 네이버와 다음 지도 서비스의 레이블과 길찾기 시 표출되는 랜드마크와 비교하여 정확도를 평가하였다. 그 결과, 네이버와 다음 레이블 219개 중에서 60.3%에 해당하는 132개가 제안된 방법으로 랜드마크로 추출되었으며, 네이버와 다음 지도 서비스에는 없지만 선택점에서 추가로 추출된 228개의 랜드마크는 지역적 수준에서 길 찾기 시 방향 전환을 결정하는데 도움이 될 수 있음을 확인하였다.

This study mainly aims at suggesting plans applicable to the outdoor of environment-friendly communities in Korea by leveraging more natural conditions and materials when creating an outdoor biotop for an environment-friendly community and generating material types and development techniques enabling a natural circulation system. To this end, materials used in the outdoor of environment-friendly communities and traditional residential areas in Korea and biotop materials found in natural areas were examined. First, when the case examples of environment-friendly communities were reviewed, biotop spaces and materials that may function as habitats were hardly found. Materials used in biotop were mainly man-made structures made of artificial or processed materials, such as concrete, stones, bricks, woods and steels. Meanwhile, the outdoor space of traditional Korean villages had stone walls, soil walls, rock piles and composite piles, which composed of natural materials such as rocks, soil and plants, that naturally formed porous spaces along with the introduction of plants and provided habitats for a variety of insects. In natural areas, naturally created biotop spaces, such as rock piles, log piles, old tree deployment, branch piles, hay stacks and defoliated leaves, were found. Meanwhile, when spaces and materials available for biotop creation were reviewed to create an environment-friendly residential complex, they were divided into fences and hedges, green spaces between parks and residential buildings, ponds and waterscape spaces, zones separating pedestrian walks and roadways, breast walls and slope boundary, plant box and pergola. For each space, materials used for creating biotops and that were found in traditional Korean residential areas and natural areas were applied and suggested.

본 연구는 물리환경 및 미기후, 쾌적성이 외부활동 지속에 미치는 영향 도출을 목적으로 한다. 본 연구에서는 외부활동 지속에 영향을 미치는 요소로 도시 내 물리환경, 물리환경에 대해 외부공간 활동자가 느끼는 쾌적성, 미기후, 미기후에 대해 외부공간 활동자가 느끼는 쾌적성 등을 중심으로 접근했다. 이에 대한 분석을 위해서 2017년 중 봄, 여름, 겨울과 같이 세 계절에 대해서 외부공간 활동자가 느끼는 다양한 쾌적도에 대한 설문조사를 수행하였다. 설문조사 응답자가 설문조사에 응답하고 있는 동안에 주변 장소의 미기후에 대한 측정을 실시하였다. 이렇게 구축된 자료를 이용하여 효과적인 분석수행을 위해서 로짓회귀분석을 이용하였다. 분석결과, 물리환경 쾌적성의 용이성 및 안전성과 기후환경 쾌적성의 온도, 바람, 일사량 쾌적성 등은 외부공간의 활동 지속도와 유의미한 관계를 맺고 있었다. 머물기 및 대화 행위 보다는 걷기와 쇼핑 행위가 물리적 환경 및 기후환경에 보다 예민하게 영향을 받는 요소임을 도출했다.

This study aims at the development on the wood-frame house construction method in hilly areas. To obey the trend of public opinion to prohibit the troublesome development on a large scale in preparing housing sites, the small housing site development in hilly areas is on the rise and consequently wood-frame house which harmonized natural topography, geographical feature and environment in hilly areas is needed. The main contents are how to make housing sites, how to make roads, how to make pedestrian ways and surroundings of water to run downhill, how to locate house, how to make between road and house, how to view inner and outer and how to make retaining wall on the wood-frame house construction method in hilly areas.

The total number of deaths by traffic accidents is decreasing every year in our country. However, in 2009, children died in traffic accidents at a rate of 2.3 deaths per 100,000 children, which was higher than the average of OECD countries (1.9 deaths per 100,000 children). In particular, traffic accidents are showing rapid increase in school zone during the past 2 years because of problems in the designation and management of school zone. Traffic safety facilities such as road sign, reflector mirror, speed bump have the ultimate limit of vehicle accidents prevention. Thus, in school zone, children safety is still not guaranteed due to illegal parking and the absence of driver's awareness of safety. Therefore, In order to protect children from traffic accidents within school zones, we have realized a safe school zone system, which enables the drivers to better know the intended school zones and creates pedestrian environment through unmanned monitoring camera, using LabVIEW.

가로조명은 이용자의 안전과 편안한 시각환경을 제공함은 물론 이용자의 요구에 맞는 쾌적한 분위기를 연출하여야 한다. 그렇기 때문에 조명기구의 선택에 있어서 미적인 측면이나 선례에 의존하기보다 가로의 이용에 필요한 요구사항과 이용자에 대한 이해가 바탕이 되어야 한다. 본 연구에서는 기존 주거단지에 사용되고 있는 가로조명기구들의 문제점을 분석하고 주거단지 가로조명이 갖는 특수성을 규명하여 이를 반영한 조명기구 디자인 및 운용방안을 제안하고자 한다.

The purpose of this study is to find the characteristics of planning factors to the outdoor space of the olympic village munchen. The result of the research are follows; 1) The horizontal gardens of the low buildings and hanging gardens on the terraces of the high-rise buildings are intended as a continuation of the concept of the modelled landscape. 2) By virtue of the choice of the type of building and the way in which the buildings are staggered, the residents have an unimpaired view of the green spaces and recreation areas. 3) Leisure value is further enhanced by the proximity of the residential arms to the footpath running north to south. 4) The terraces allow the residents to enjoy more sun and sky, so that the view into the distance is the rule. 5) To improve orientation, the pedestrian paths to the residential wings are also situated directly over the underground vehicle-access roads.

This study aims to evaluate the cultural street and to find ways to revitalize a culture street. To achieve this, the study relied on empirical study method and the descriptive method; additionally, present condition survey was performed with a user interview. As a result, the item of 'night visit' shows the highest mean and the item of 'convenience of walking' follows. It means that this street has such a good condition in the convenience and accessibility of physical environment that it gives pedestrians pleasure like night activity and satisfying their curiosity. 5 lowest items of inquiry, however, are all about regional history and origin. It means that this cultural street did not reflect the history and embody the original form of the street. Also, this study proposes 4 type of street; a street with contents, a street with sequence, a street for pedestrians, and a street with identity.

The purpose of this study is to consider the characteristic of residential life and space in Cohousing and the harmony of privacy and community in it. First consideration is to figure out concepts and case studies of Cohousing. Then, the harmony(of privacy and community) in Cohousing is evaluated within two domains, namely, domestic life and residential space. Consideration of such harmony(of privacy and community) in domestic life focuses on community relations as they manifested, that is, in traditional neighbours roles of caring, and mutual support and in community roles of active participation, common meal and share. Consideration of such harmony within residential spaces is based on the role of Common House, pedestrian traffic and shared outdoor areas. By these means, Cohousing demonstrates new possibilities for a more harmonious residential environment.
