This study examined and analyzed locational conditions of apartment houses in regional small cities to provide basic materials to set direction and index of view management of apartment house and thus the results of the study are as follows. 1. The number of story of apartment houses 'below five story' was 48% and area of apartment house was 'over 500m$^2$ and below 1000m$^2$' in 31% of the whole regions. 2. As a result of analyzing correlations with changes of floor of apartment house by construction year, apartment houses below 10 story were mainly built between 1991 and 1995 and high-storied apartment houses over 11 story were mainly built since 1995 and apartment houses over 21 story were built since 2000 and these high-storied apartment houses were main cause of hindering view of small cities. Accordingly, establishment of guideline of building high-storied apartment house which can be a primary obstacle of urban view and regulations of height are needed.

Top-down method is widely used for urban area construction for its advantages in reducing environmental problems such as dust and noise, and saving construction cost depending on given conditions of a construction site. Because the excavation and construction of super- and sub-structures of the building have to be proceeded simultaneously, a column has to be embedded prior to excavation. This column is called a pillar column or pre-founded column. Usually a wide flange section is used for these columns. To place the columns, usually the diameter of casing holes needs to be larger than the section of the wide flange itself in order to accommodate a couple of tremie pipes for pouring concrete. In this paper, a newly developed method of using circular pipe as an alternative to the existing wide flange section is discussed. The crucial part of the new method is to develop a connection between the circular column and concrete flat slabs. For shear force transfer from concrete slab to the concrete filled tube (CFT) column, shear jackets with studs and shear bands are proposed. The studs are welded on the jackets at shop and placed around the circular column on site. The shear bands are welded on the outer side of the CFT at shop and inserted into ground with the CFT. Test results and application of the method to a construction site are also provided in this paper.

This paper depicts a case study of the BIM (Building Information Modeling)-enabled evaluation of design alternatives for an actual remodeling project in Yeongwol, Korea. The increase of urban population and income followed by the growth of economy has derived massive supply of grand scale housing project in Korea since 1970s. Consequently, building remodeling became one of the feasible resolutions for renovating such old housings in these days. This paper aims to introduce a technical approach to such remodeling projects based on BIM-enabled applications focusing on quantitative analysis of design alternatives. Among the technical issues of such building remodeling projects, this paper focuses on the BIM-enabled area analysis and comparison between design alternatives to support decision-making even in early phase of remodeling design process. BIM and its variety of applications have broadly influenced the domain of AEC-FM (Architecture, Engineering, Construction, and Facility Management) within the lifecycle of buildings. As one of the applications facilitated by BIM, the automated area calculation and scenario-based comparison between alternatives can play an important role in the early phase of remodeling project. We modeled three design alternatives (buildings) and three housing modules (units) based on the actual case in Yeongwol city, Korea using a BIM design authoring tool. Nine combinatorial BIM models were demonstrated for the BIM-enabled review process described in this paper. To determine the most optimal design scenario among nine alternatives, this paper demonstrates a result of the conducted spatial program review. The main subject includes specific spatial program issues on; 1) the number of unit spaces; and 2) area of individual/grouped and private/shared spaces.

The purpose of this study was to suggest an improvement proposal for colors in urban environment with special regard to the surface color and their situations of apartment buildings in Seoul. For this goal, 167 cases of different color types of apartment buildings were surveyed. And, the survey was performed in the view of color by areas, by localtion, by builder, by paint year, by built year, by appearance of building, and by surface texture to prove the influencing factors on the surface colors. These collected data analyzed and compared with the existing studies to find out the changing trend of colors. The results are as follows : 1) The use of neutral gray($26.4{\%}$) and warm color(YR, Y, GY; 56.4%) were dominant and the usage trend of higher 'value'(87.4%) and lower 'saturation'(73.0%) was obvious. Especially, the use of PB and P was noticeable. 2) In comparing the existing studies, the changing trend in the surface color pattern was found. That is, neutral gray was used dominantly in 1970's, warm color(YR, Y)in the middle of 1980's. In the end of 1980's, warm color were also used dominantly same as before and GY, PB, P were used noticeably with some rising tendency of higher 'value' and lower 'saturation' was obvious. 3) The results of analysis by localtion shows that the different color groups might exist in Seoul city. Neutral gray and YR were dominant in zone I. Warm colors(YR, Y, GY)were prevailed in zone II, III, IV. In zone V, many colors were evenly used. In zone VI, middle values at warm color were dominant. Progressively, these color groups with further study could be considered in the color management in urban environment possibly. 4) Surface color of apartment buildings were different from their builders. 5) Concerned with the painted year, the use of higher 'value' and lower 'saturation' was increased gradually with the change of times. 6) the analysis by the built year revealed that the 'value' of surface colors on the old buildings was lower than that of the new ones. 7) The 'value' of colors on the surface with texture was higher than that of the surface without texture. 8) In the combination of two colors, the use of 'value' with difference at the same 'hue' was found harmonions in many cases, but the 'saturation' in usage was included in the ambiguity (Moon & Spencer's term). The ambiguity in color harmony should be improved in the near future.

In Japan, the vacancy rates of office buildings have been at high in big cities since 1992. This problem is especially acute in Tokyo, where it is estimated that over 2.27 million square meters of office floor area will be oversupplied in 2003: big urban redevelopment projects will be completed in 2003. Under these circumstances, International Cooperative Research and Development on Sustainable Urban Management by Conversion of Buildings, called “SUMCOB”, has been carried out. This research aims to regenerate urban areas by converting redundant offices into flats, although instances of conversion are still very few in Japan. This paper introduces part of current results by SUMCOB, and discusses legal problems with conversion and basic capacity of vacant offices in Tokyo. It has been confirmed that there are no constraints concerned with Real Estate Registration Law (although it requires the change of the registration after conversion). and City Planning Law. However, some criteria are incompatible with Building Standard Law and Fire Service Law if the use of the building is changed from offices to flats. Typical incompatibility between offices and flats is lightening. If the buildings do not satisfy criteria for flats, the cost of renovation works for conversion will increase. To examine the basic capacity of vacant office buildings for conversion, field surveys in Tokyo have carried out at three areas: Kodenmacho (Chuo-ku), Toranomon (Minato-ku), and Iwamonocho (Chiyoda-ku). They are typical office areas that are included in center core of Tokyo. In Chuo-ku, the oldest commercial area in Tokyo, textile merchants have been located their headquarters. In Minato-ku, many rental office buildings have been located and several large scale redevelopments are advancing. Chiyoda-ku includes Marunouchi area, which is the prime office area in Japan. Thirty percent of the buildings in survey areas suffer from over twenty percent vacant floor rate, and fifty five percent were constructed before 1990. Especially most of buildings over forty percent vacant floor rate were constructed in 1980s. Vacant office problems haven't been seen in old buildings in Tokyo yet. The number of dwelling units made from office space will influence the conversion scheme. Seventy percent of the office buildings in survey areas have floor area of less than two hundred square meters. If they have been subdivided into two bedrooms type or three bedrooms type, the number of dwelling units in a floor would be less than three. The difficulty of conversion planning derives from frontage size, depth size, and their proportion. The five categories are proposed to grasp actual requirements for converting offices into flats.

현재는 도시 아이덴티티(City Identity)가 과거의 기업경영 전략으로서 디자인 통합계획(Visual Identity)이 아닌 지역 고유의 역사와 문화적 유산을 포함하고 경쟁력 강화와 지역성을 부각시켜 잠재되어 있던 지역의 이미지를 새롭게 구현 및 활성화에 그 목적을 두고 있다. 이에 경기도 31개 지자체의 도시 아이덴티티 디자인은 과거에서 벗어나 미래지향적이고 간결하면서도 모던한 이미지를 구축하고 기하학적인 인공모티브를 이용한 차별화된 아이덴티티를 구축해 나가고 있다. 하지만 일부 지자체에서는 과거의 도시 아이덴티티가 존재하였음에도 불구하고, 리뉴얼의 개념이 아닌 새로운 BI를 개발하여 CI를 대체하거나 CI와 BI역할을 대행하고 있어 심볼마크의 경계선과 기준점이 점점 모호 해지고 있다. 뿐만 아니라 비전이 담긴 슬로건을 BI로 사용하고 있는 사례가 존재하고 있어 경기도 지자체 현황분석과 방향성을 제시하여 전문적인 CIP관리가 요구된다. 따라서 본 연구에서는 경기도 31개 지자체의 이론적 배경분석과 학술연구를 통해 심볼마크의 현황분석을 실시하였고 심볼마크의 본질적 의미가 형태론적으로 어떻게 표현되고 해석되는지를 도식화하여 I.R.I 이미지 공간을 최종 분석하였다.
