With the aging of buildings, the number and importance of regular inspections of buildings are increasing. The current safety inspection goes through a procedure in which a skilled technician visits an old building, visually checks it, takes a photo, and finally organizes and judges it at the office. For this, field personnel and analysis and review personnel are required. Since the inspection procedure includes taking pictures, a huge amount of data has been accumulated from the time digital photos were used to the present. When a model that can check cracks outside a building is developed using these data, manpower and time required can be greatly reduced. Therefore, this study aims to create a model for classifying cracks that occur outside the building through the artificial intelligence method. The created model can be used as a basic model for determining cracks only by external photography in the future, and furthermore, it can be used as basic data for calculating the size and width of cracks.

최근 도심재개발사업의 증가로 기존 건물 철거 후 신축공사를 하는 사례가 증가하는 추세이다. 그러나 현재까지의 연구는 신축공사에 따른 인접굴착이 지하철 터널에 미치는 영향 검토에 국한되어 왔다. 이에 따라 기존 주차장 건물을 철거한 후 신축공사가 이루어지는 ${\bigcirc}{\bigcirc}$건물 신축사업을 연구대상으로 선정하여 상부 건물 철거 등으로 인한 하중제하 및 하중재하에 따른 지하철 터널에 미치는 영향 검토를 수행하였다. 수치해석은 기존 건물 철거를 고려한 경우와 고려하지 않은 경우에 대해 MIDAS/GTS를 사용하여 3차원 수치해석을 수행하고 터널 변위 및 부재력 결과 분석을 통해 기존 건물 철거가 지하철 터널에 미치는 영향을 검토하였다. 그 결과 기존 건물 철거를 고려하는 경우가 고려하지 않는 경우보다 지하철 터널에 미치는 영향이 더 큰 것으로 나타났다.

Existing old reinforced concrete buildings could be vulnerable to earthquakes because they were constructed without satisfying seismic design and detail requirements. In current seismic design standards, the target collapse probability for a given Maximum Considered Earthquake (MCE) ground-shaking hazard is defined as 10% for ordinary buildings. This study aims to estimate the collapse probabilities of a three-story, old, reinforced concrete building designed by only considering gravity loads. Four different seismic design categories (SDC), A, B, C, and D, are considered. This study reveals that the RC building located in the SDC A region satisfies the target collapse probability. However, buildings located in SDC B, C, and D regions do not meet the target collapse probability. Since the degree of exceedance of the target probability increases with an increase in the SDC level, it is imminent to retrofit non-ductile RC buildings similar to the model building. It can be confirmed that repair and reinforcement of old reinforced concrete buildings are required.

This study aimed to identify changes in the physical properties of artificial mineral-fiber materials used as building insulation that had been installed in the outer walls of buildings for a long time. To achieve this goal, glass fiber and rock wool were collected from outer walls in actual buildings and their acoustic and thermal performances were measured. These were compared with measurements from similar products manufactured recently. The results showed that old, used samples had a lower sound absorption coefficient compared to recently manufactured materials. The old samples also displayed increased compressibility compared to new materials. For example, the compressibility difference for glass wool was 7.32 mm. Old samples had a dynamic stiffness $1.28MN/m^3$ higher than new material samples. The thermal conductivity of both old and new samples increased within creasing temperature. They showed similar results at temperatures between 0 and $20^{\circ}C$.

우리나라에 공공도서관이 많이 없다. 그 이유는 국민들의 공공도서관에 대한 중요성 및 필요성에 대한 인식 부족과 중앙 및 지방정부의 도서관건립에 대한 인색한 투자와 함께 효과적인 공공도서관 건립정책이 없었기 때문이다. 이제 선진국과 같은 작은 도서관 건립 및 운영 정책을 펴야 한다. 지역 재개발 및 아파트 재건축 추진은 이들 지역에 작은 규모의 마을도서관을 건립할 수 있는 좋은 기회이다. 서울에 있는 J아파트는 재건축을 추진하고 있는데, 이 시점에서 새로운 위치로 옮겨가는 동사무소와 우체국을 하나의 건물로 신축하고, 이 건물 내에 공공도서관을 설치할 수 있을 것이다. 도서관을 이들 시설들과 함께 1층에 배치한다면 시너지 효과를 발생시켜 세 기관 모두에게 도움이 될 것이다. 이처럼 재개발 및 재건축 지역에 공공기관 혹은 상엽시설과 함께 복합건물 형태로 작은 도서관을 건립하는 것은 우리나라 공공도서관의 부족 문제를 해결 할 수 있는 좋은 방법이다.

The purpose of this study is to clarify the characteristics between the type of daily routine and spatial configuration of activity areas in classroom and provide alternatives for space planning of activity areas in classroom of child-care centers. This study used the content analysis on daily activity plan and floor plans through field survey. Analysis on floor plans was conducted for 35 classrooms in 9 child-care centers which allowed field survey. The results of this study were as follows; There was no significant difference for classroom size according to the type of daily routine in 3 to 5-year-old classrooms. The average size of classrooms was $61.6m^2$ for care oriented type, $41.4m^2$ for indoor activity oriented type and $48.8m^2$ for group activity oriented type. There was no significant difference in composition of activity areas in classrooms according to the type of daily routine. In case of 0 to 2-year-old classrooms, they were composed of 6 activity areas including gross-motor, role play, block building, language, creative expression, exploration/manipulation. Activity area of the most low frequency was gross-motor area. In case of 3 to 5-year-old classrooms, most classrooms were composed of all the 7 activity areas including art, tone and rhythmic, block building, role play, language, math and science. Most accessible and central areas in 0 to 2-year-old classrooms were gross-motor and role play. Also, most separate areas were exploration/manipulation and block building. Most accessible and central areas in 3 to 5-year-old classroom were art and math. Also, most separate areas were tone and rhythmic and science.

Purpose: Now a day, Most of the residential house in Korea consists of apartment buildings. However, in the case of old apartment buildings, dwelling environment condition depends on management effort by residents. But we can't rebuild or restructure only old single dwelling unit in apartment buildings. And we can't move every single dwelling unit in the apartment building. Therefore, this study suggests a prototype of combinable container dwelling module apartment. Method: The method of research is exploring the case of previously constructed containers. Based on the case, This study suggests prototypes to create a variable apartment design with dwelling container units. Based on the prototype, various combinations are proposed to produce various types of dwelling space. Finally, this study makes an example plan for the apartment by using the container unit modules. Results: This study suggests combinable container apartment building prototypes. And it may be a fundamental study of changing the apartment building concept.

Many people think, in common that An expansion toward outer city is a development, and it can be a general trends in a new development in a growing city. But We can see many case which moving of a public building are considerate as a core element to promote the new development towards outer city, and that is a negative element of slum in central area and community making. There are many aspects to pursue sustainable urban structure of in a city, and public building is a very important element to manage deteriorate central area from social slum in a old town. In this presentation, three project, Local Authority office of Chonnam province, Kwangju Station, and Hyper Urbanity, and it shows sustainable concept of the public building as a core in a city development. The effect of the projects are expected sustainable development and community in terms of social, cultural and historical aspects.

In January 2018, the Ministry of Education published "Seismic design criteria for school buildings" and "Manual for seismic performance evaluation and retrofit of school buildings" to evaluate seismic performances through linear analysis. This paper evaluates the seismic performance of an old school building through the linear analysis. The target building was constructed in the late 1970s, and the seismic-force-resisting system was assumed to be a reinforced concrete moment frame with an un-reinforced masonry wall. As a result of the evaluation, the target building does not satisfy the 'life safety' level of 1.2 times the design spectrum. The average strength ratio of moment frames, an indicator of the level of seismic performance tends to be controlled by beams. However, through the Pohang earthquake, it was known that the short column effect caused by the partially infilled masonry wall caused shear failure of the columns in school buildings. Therefore, it is necessary to improve the linear analysis so that the column controls the average strength ratio of moment frames.

This study is intended to formulate the issues through the status analysis and image evaluation for each street on the basis of colors for the outdoor advertisements for part of street side in the oldest downtown for its construction year. Analysing the business type of the street side, it displays the identity of the fashion business area and the color status shown on the outdoor advertisement did not consider the harmony on the other business type and building improvements that it displays chaotic street views in overall. Status of color for the outdoor advertisement compared and analyzed for each street-side to be analyzed with high color contrast with the building structure and outdoor advertisements than the Street B side where there are many businesses of fashion sundries and fashion clothes to form more complicated street scenery visually for the Street A side. The color combination principle of building structure and outdoor advertisement was shown to be the factor for the contrasting unity and diversity. In order not to stimulate this visual confusion, the colors of outdoor advertisement has to be applied on the basis of the color guideline based on the color combination principle of outdoor advertisement and building structure to have the aesthetic harmony overall. As a result of analysis using the KJ method, the present image of the old downtown area was shown with the adjective vocabularies of "complicated", "out-dated", "chaotic", "disorganized", "dirty", "suffocating", and "unilateral", and its image to strive for would be in a total of 6 adjective vocabularies of "well-arranged", "young", "dynamic", "sophisticated", "personable" and "neat", and it has presented the basic foundation of color guideline of outdoor advertisement fit for its image.
