This paper compared vertical temperature distribution between the existing balcony model without ventilator facilities and the improved balcony model with ventilator facilities using differential equation. As the air inside of balcony is heated by solar radiation this heated air is not exhausted in the existing balcony, remaining stagnant. The air temperature distribution was $26.7{\sim}29.3^{\circ}C$ in balcony without natural ventilator system. This heated air affected the rising air temperature of adjacent spaces such as living room and bedroom in the existing balcony. But, as the heated air inside of the improved balcony model is exhausted through natural ventilator facilities in summer, the air temperature in balcony has fallen. The air temperature distribution in improved balcony was $24.8{\sim}26.7^{\circ}C$ for the inlet air speed of 1 m/s and $24.6{\sim}26.7^{\circ}C$ for the inlet air speed of 3 m/s. The energy consumption of the improved balcony is 2.5 times less than of the existing balcony. The improved balcony with the closed damper makes a roll as the existing balcony in the aspect of the heating effect. When the heated air in the improved balcony is supplied, the air temperature is raised and the ventilation effect in adjacent spaces was improved.

산업단지는 1960년대부터 우리나라의 경제성장과정에서 기업의 공간적 집적을 통한 수출선도와 산업경쟁력강화에 큰 기여를 해왔다. 하지만 노후산업단지가 증가하였고, 이에 산업단지의 효율적인 재생을 통하여 경쟁력을 높이는 것이 시급한 과제로 부각되었으며, 우리나라의 대표적인 산업단지인 구로공업단지는 산업단지 구조고도화사업을 통하여 첨단산업단지로 변모하게 되었다. 그러나 국지적인 변화속에서 이루어진 산업단지 구조고도화사업은 산업단지와 주변지역을 유리시키게 되었고, 건축적 공공성 확보 측면에서 산업단지는 도시에 속하지 않는 외딴 섬처럼 보이게 되는 결과를 초래하였다. 따라서 본 연구는 구조고도화사업의 대표적 성공사례인 서울디지털산업단지를 대상으로 산업단지와 접해 있는 연접지역을 대상으로 물리적 특성을 분석하고, 도시 맥락적 측면에서 내재되어 있는 문제점에 대한 해결방안을 제시하고자 하였으며, 이러한 방안으로 이질적 도시공간 조성을 지양하고 도시맥락적 단절을 해소하기 위해서 경계에 대한 장소만들기적 접근이 필요하고, 이를 위하여 지구단위계획 관련 법제적 개선을 통해 산업시설구역을 지구단위계획으로 지정하는 것을 제시하였다.

The purpose of this study is to investigate tendencies on land use in the housing site development district by grasping the characteristics of changes of building use at the borders of single-detached housing area for planning single-detached housing area in the future. It is divided the borders of detached housing areas into three types, educational facility, parks and green spaces, and apartment complex, and then analyzed the characteristics of each location after a field study. It is summarized as follows. First, there were stationery and flour-based meal stores in adjacent borders near educational facilities, suitable for students' interest and motion patterns, and it is required to consider about frequent children's action in the street. Second, there are many facilities for park users and residents, such as educational institutes and restaurants in adjacent to borders near parks. In borders neighboring buffer green belt areas, warehouses and vacant sites were mainly distributed. And the revitalization of streets was lower than others, because a road was used as a parking space. Third, there were realty dealers, food stores, and laundries which provide the dwellers with service in adjacent borders near multi-family housing.

We investigated space establishment and land use of children's parks by studying movement of users in and out of the parks with a questionnaire survey, video and analysis, and then analyzed the characteristics of how the facilities and the space of the parte are used. The results are as follows. First, when considering the character of the facilities of children's parks, entertainment facilities should receive priority followed by those for relaxation and those for convenience. When considering the position of facilities in the parks, because activity spaces may have similar functions to multi-purpose paved spaces, common use of these two spaces should be considered. Entrances and lines of movement should be kept in mind. Second, when considering the surrounding land uses, in case a play facility at a large-sized complex or an elementary school is adjacent, the exercise facilities may be more important, followed by play and rest facilities. In case there is a broad path around the parte, the way in which movement occurs into the central axis should be considered so that the other side of the broad way is not included in the children's play space. Third, proper control of roads adjacent to the parse is needed to protect children from danger.

오늘날 도시 과밀화로 인해 한정된 부지를 효과적으로 사용하기 위해 기존 구조물과 인접한 조건에서 신규 구조물이 시공되는 경우가 많아지고 있다. 기존 구조물 근처에 신규 구조물이 시공되는 경우 기존 구조물에 의한 간섭효과가 발생할 수 있어, 이와 관련된 다양한 국내외 연구들이 진행되고 있지만 실험실 규모에서 모사할 수 있는 근접 구조물의 조건들이 한정적이라 실제 현장 조건을 제대로 반영하지 못하고 있다. 아울러 근접시공에 관한 명확한 기준과 역학적 거동이 규명되어 있지 않아 연구가 필요한 실정이다. 따라서 본 연구에서는 다양한 크기의 근접 구조물 시공 조건에 대한 지지력 및 침하량 변화를 관찰하기 위한 실험 연구를 수행하였다. 실험 결과 사질토 지반에서 구조물이 특정 거리 내에 근접 시공되는 경우 간섭효과로 인해 신규 구조물의 지지력 상승 효과가 확인되었으나 기존 구조물의 침하량이 증가하여 실제 근접 시공 시 면밀한 검토가 필요함을 확인하였다.

This study is aimed at understanding objectively on the visual perception of atypical space and form in contemporary architecture. It is accomplished to compose the various form and the atypical space in contemporary architecture, which by means of applying digital technology to architecture is able to materialize complicated form and space. Therefore this the sis is needed to understand user's senses and affects in atypical space and form. Atypical space is able to interpret geometrically and analyze quantitatively into visual perception. This analysis is applied to Isovist used as quantitative analysis recently, and physical analysis of space used as quantitative analysis defined to vertical elements, which is analysed comparatively to visual perception in observer's point and characteristics in spatial elements. Examples are selected to four examples represented to typical and atypical space in contemporary houses. As examples are analysed to visual perception of spatial character, this study is intended to understand to spatial character in aspects of spatial composition and observer's visual perception. In results of perceptive analysis on four spatial examples, Atypical spaces are composed of changeable spatiality, which are composed changeably of the relational method with adjacent spaces. Also, typical spaces are composed monotonously of spatiality and relational method on control of the length in boundary plane and openness.

In contrast to apartments, detached houses offer the possibility of more than one entrance connecting interior and exterior spaces. This study examines the location, function, and use of second doors in detached houses in rural areas. The study employs survey and interviews conducted in 2015, focusing on 18 detached houses among 40 houses previously surveyed in 1995. In 1995, 21 second doors were found, while in 2015, 19 were found. The study led to the following conclusions. First, most houses did have second doors installed by 1995 or 2015. Second doors tended to be installed in kitchen and utility rooms. The function of second doors was most closely connected to the kitchen because utility rooms were placed adjacent to kitchens. Secondly, changes in the use and number of second doors were changes in family life cycle and composition, the need for new equipment facilities, the use of new architectural materials, and the installation of new second doors for extension of space. Finally, exterior spaces accessed by second doors tend to be a meeting of semi-interior or semi-exterior space and exterior space only. Those spaces tended to be designed for kitchen fixtures or to support kitchen activities.

This study examines the properties of spaces where historical and cultural resources have been preserved in the street system of Daegu Yakryeong market district, by using Space Syntax methodology. The results were obtained through ASA(Angular Segment Analysis) on each node (spatial unit) in the street network. An overall characteristic of spatial configuration in street system of the surveyed district is that nodes in the street network tend to form socially integrated spatial structure to allow easy access to each space in the system. There are a small number of socially isolated spaces in the street system, which are located at nodes in narrow streets adjacent to the roadway outside the district, or in narrow alleys between early modern Korean buildings. More than half of the surveyed spaces have high levels of social integration, which contain buildings playing a central role of the community, a traditional street market, symbolic landmarks. In conclusion, it is expected that the achievements of this study will contribute in leading to rational land use planning for sound and sustainable development of historical and cultural resources in an urban district.

Urban parks and open spaces provide the community residents with the most easily accessible source for outdoor recreation, contributing also to the improvement of quality of natural environment in urban area. The demands of urban residents' for more and better green area are ever-increasing. However, the level of most urban open spaces which are easily accessible for residents are not satisfactory to meet the residents' demand in availability and in quality as well. Most existing urban open spaces are simply built of green areas only or have been developed in almost identical design with little consideration for individual uniqueness of the site. When developing neighbourhood parks in urban housing complexes, for example, little consideration is being given to topographical conditions, interrelation with the adjacent green area, or viability of the urban ecosystem. In many cases, urban park development projects are being done with serious negligence of natural properties of the site, by even destroying existing healthy woodlands. for instance. The objectives of this study are; -To survey on the domestic and the overseas cases of regulatory systems, development status and planning methods for urban open space. -To identify underlying issues of residental park developments in urban housing projects and establish appropriate improvement measures thereof, by studing and analyzing current-use data of developed urban parks and management status thereof. -To establish improved standards for urban open space planning, by integrating above surveys and studies, and recommendation for revision of related legislation is also presented to implement these standards.
