도시재생종합정보시스템에서 전국 시군구단위 도시쇠퇴 현황은 인구사회 산업경제 물리환경이라는 종합적인 지표를 활용하여 분석하고 있다. 그러나 읍면동 단위의 도시쇠퇴 분석은 신뢰성 있는 데이터 확보의 어려움으로 몇 개의 지표만을 제공하고 있는 실정이다. 도시재생 사업이 활성화되면서 좀 더 정확한 도시쇠퇴 분석이 요구되는 상황이여서 이를 해결하기 위하여 빅데이터 기술을 적용한 방안을 제시하였다. 제시된 방법으로 분석된 지구단위의 도시쇠퇴 현황은 세밀한 공간단위의 도시쇠퇴 분석은 물론 추후 도시재생 모니터링 등에 활용될 것으로 기대된다.

쇠퇴되어가고 있는 도시를 부흥시키고자 하는 도시재생 사업의 성공을 위해서는 종합적인 정보체계를 갖추어야만 한다. 먼저 정확한 데이터를 통한 도시의 쇠퇴현황을 진단하고 쇠퇴의 유형에 따른 올바른 대상지를 선정하여야 하며 주민의 참여를 유도하는 정보체계 및 사업의 모니터링을 통한 지속적인 관리체계를 수립할 수 있어야 한다. 본 연구에서는 이러한 도시재생을 효율적으로 수행할 수 있는 정보체계를 도시재생종합정보시스템를 중심으로 제안하고 운영관리방안을 제시하였다. 제시된 정보체계 속에 유기적인 정보의 활용을 통해 우리나라 도시재생 사업의 효과적인 수행을 기대할 수 있다.

Colombia experiences a population growth in their metropolitan areas through an accelerated urbanization process, a housing deficit and a shortage of urban developable land. To solve these problems, the central government developed a national policy for a large-scale housing city development including supra-municipalities planning instruments such as Macroprojects. However, the amount of housing land supplied by this policy is insufficient and additional policies for shortage housing and qualitative deficit are required, particularly in regions with a high concentration of population. The purpose of the study is to compare urban development systems of Colombia and Korea and explore the possibility of applying guidelines to Colombia through i) comparing the capital region cities of the two countries with an asymmetry context method, ii) comparing both urban planning system founding similarities and differences, and iii) suggesting new urban development challenges in the Bogotá metropolitan area based on Korea's new town experience.

The purpose of this study is to investigate the architectural visual identity, and scheme of conceptional extent of architectural visual identity through literature research and sample analysis by design factors for apartment design. Korea National Housing Corporation's Mapo apartment put first caterer which is continued about 30 years to solve shortage of houses by beginning and the impact of IMF and the price decontrol on second half in the 1990s have changed the housing status to commercial goods. Construction companies have introduced brand concept to satisfy consumer's appetite in production of house goods including apartment under market situation. Importance of visual identity in apartment design occupies has risen in heftily. However most companies are in condition of stay on two-dimensional application that uses symbol, logotype, and character assistance. Several high position construction companies are trying architectural visual identity, but those are applied in partial element and those are not going forward to systematic classification and synthetic visual identity plan within peculiarity of apartment complex. This study is to grasp plan and design tendency to acquire identity of design element of construction field and goods through design examination. In conclusion visual identity in apartment design is architectural visual identity on all of 2 dimensions and 3 dimension for application. Architectural visual identity is a language of form that prescribe identity about external appearance in combination with brand image.

The corrosion of RC structures demonstrates very complicated forms of deterioration intermingled together but all pointing to a decrease in the durability of RC structures due to the corrosion of reinforcing bars. Until now, nondestructive techniques, such as half-cell potential and polarization resistance, have been widely available in the world. The former provides information on the probability of corrosion while the latter is associated with information concerning corrosion rates. Inversion by the boundary element method (IBEM) was developed for considering concrete resistivity. The applicability of the procedure was examined through a numerical analysis and electrolytic tests for RC slabs. A distribution in such concrete resistivity is relatively inhomogeneous including cracks on the surface of slabs. Regarding cracks in concrete, the relative coefficient of concrete resistance was introduced to perform its analysis. Further, the procedure will be developed to identify the corroded region visually using 3-D VRML.

Land development is an essential process to provide lands for housing, industrial, and tourism complex. The development and application of construction automation technology in land development construction are, however, not matured yet. Since land development requires massive investment in terms of cost and effort, the benefits of implementing earthwork construction automation technology could also be enormous. As such, the deployment of advanced technology needs to be assessed. In this paper, by investigating domestic and international advanced earthwork technology, 8 candidate technologies to be developed is derived. These technologies are then prioritized using AHP and web-based survey that distributed to experts in the field of civil and infrastructure. As a result, advanced earthwork fleet management platformization and tele-operation systems for unmanned earthwork are identified as the top priority. Besides through sensitivity analysis, the trends of the technology rank by the weight distribution of the evaluation factor is investigated. Consequently, the research and development processes for the earthwork construction automation technology in land development are explored and based on the results, the research and development road map plan is established.

The purpose of this research is to analyze the business process in which Korea Land & Housing Corporation utilizes spatial DB of NSDI(National Spatial Data Infrastructure) for compensation service. By the analysis of spatial data connected with compensation service, the influence of the matching error among spatial data on the business process for the service is identified and it is required to draw a direction for improvement in it.

This study focused on 15 parks to investigate the actual developmental conditions for preservation type parks and artificial type parks in the 9 residential land development sites managed by the Korea Land Corporation in Daegu and Gyeongsangbukdo area from 1994 to 2002. Emphasis is placed upon the types of land use, park arrangements, park facilities, types of planted trees and landscaping expense, with a view to discovering ways of improving the efficiency of future park development.

Electret filter media are used in general ventilation filters, disposable respirators, vehicle cabin filters, vacuum cleaners and room air cleaners. There are basic mechanisms of interception, inertial impaction, diffusion, gravitational settling, electrostatic attraction by which an aerosol particle can be deposited onto a fiber in a filter. The ability of fine particle removal strongly depends on the electrostatic forces between particles and polarized fibers. Thus, the stability of the fiber polarization is a major factor in the reliability of electret filters. In this study, electrical properties and filtration performance of electrospun filter media are quantitatively investigated. Electrical properties of electrospun filters have been studied on surface charge potential and surface charge density. Also the filtration performance of the electret filters are evaluated on collection efficiency. Electrospun filters show same collection efficiency with low pressure drop compare to commercialized HEPA filters. Surface charge potential and surface charge density of electrospun filters are increased with increasing applied voltage. Also collection efficiency of electrospun filters is increased with increasing surface charge potential and surface charge density.

The purpose of this study is to present both problems and improvement plans on the bidding system of the Korea National Housing Corporation, which orders apartment houses professionally. For data gathering, this study used data from electronic procurement system from 2001 to 2005. The research method of this study is to analyze the data categorized into four types: changes of ordering and contract price ration, the lowest-pricing bidding system, and permanent projects by grades. As a result of the analysis, the amount of ordering is biased in favor of particular level. Finally, this study present following improvement plans: 1) screening system and the lowest-pricing bidding system need to be supplemented, 2) the contract price ratio and the amount of ordering should be controlled, and 3) the improvement of PQ and the introduction of the list of Qualified companies by types need to be presented.
