The purposes of this paper are to review the shifts and changes in urban planning environment, and to grasp how the new 'National and Urban Planning Law' accommodates these changes. In order to accomplish proposed schemes, I suggest that the following three details should be considered for the proper way of Urban Planning Information System(UPIS) from the beginning stage. First, new techniques are required to realize the new concepts in 'National and Urban Planning Law' with GIS and constructed DB by NGIS, as planning support systems. Second, the status of UPIS rises to the highest status among land-related information systems. Third, to adapt the UPIS to the decision support system, the restructuring of urban planning itself should be proceeded under considering the changes of concepts, paradigms and techniques.

Although a conservation laboratory is a kind of hospital for cultural assets, it is often planned on the standard of ordinary offices. In this study, things and conditions to be considered for a new conservation laboratory were discussed and suggested briefly, for the sections of architecture, electricity and lightning, air condition, fire protection, machinery and tools. As methods of creating a workspace adequate to conservation work, the method of dividing workspace on the basis of workstand and the method of placing machinery and tools on the basis of water supply and sewage systems were explained., Because a conservation laboratory varies in its duties and functions, it seems difficult that all the standards and conditions suggested in this study be fulfilled in every case. But understanding general standards and conditions and choosing ones adequate to special functions of each laboratory will be helpful to planning a new conservation laboratory.

Estimating tunnel construction time and costs are the most fundamental part of a tunnel project planning, which has been generally assessed on a deterministic basis until now. In this paper, excavation cycle time was investigated for two road tunnels and one subway tunnel, and the results were compared with the Standard of Construction Estimate (SE), which is made for the estimation of construction time and cost in a design stage. The results show that the difference in cycle time between SE and actual cycle time is 50%, 7% and 31% respectively for the three tunnels, which means that SE does not reflect practical operation time. The major reasons of the difference are skilled level of tunneling workers, the change of operation sequences for more effective operations, much more complicated working atmosphere in a tunnel than the assumption of SE etc. Finally, even though the results can not be generalized since investigated tunnels are only 3, but it is thought that SE needs to be upgraded into the model able to consider quite common situations through additional tunnel investigation and studies in the future.

The national land use plan that targets the whole national land and all kinds of urban plans that targets a city or a part of city must be performed continuously now and after that. Therefore, the importance of land use plan, that is included in those plans, is very big and crucial. This study scrutinizes the detail zoning land suitability analysis which bases on urban basis plan and the GSIS application plan about allocation, applied various basic theory which is arranged in that course to study area, and try to develop the land use suitability analysis system, a application system The programing language used in system development is the AML of ARC/INFO. On this study, the results divide into four parts. First, we develop the land use suitability analysis system and can simplify and automatize a complicated analysis course and this system will be more useful to the land use suitability analysis. Second, the analysis range is expanded, considering the circumstance environmental factor of planning area outside. So we can implement more comprehensive analysis. Third, we apply a precedency conception and a legal restrictive element that base on urban characteristics and urban space structure theory to this study, develop a computerized method about distributive method, and can allocate the detail zone in the various ways. Finally, the next studies that can clear the detail zone suitability criteria and the correlation of the relationship of materials are essential to improve the accuracy and confidence in this analysis.

In this study, a GIS-supported system is used to measure the effect of social infrastructure improvements. Benefit evaluation approach is based on two types of approaches -the simple hedonic approach and Rosen's two step approach. The land attribute data for both approaches are efficiently collected and generated in a GIS-supported environment. Moreover, it conveys more objective and correct data. The benefits are estimated on real locations by using GIS. The potentiality of the developed system for practical application has been verified by its application to Joban New Line in Tokyo metropolitan area. By incorporating benefit evaluation routines into GIS, the proposed system will be a useful tool for decision making on the improvements of social infrastructure.

도시 지역의 대부분을 차지하는 건물에 대한 3차원 정보는 도로, 교통 등의 시설물관리시스템 구축, 도로계획, 택지개발, 도시계획 등 여러 분야에 필요하다. 현재 항공사진, 고해상도 위성영상, LiDAR 자료, 수치사진측량 시스템 등의 보급과 분석 알고리즘의 발전으로 인하여 도시지역 건물 3차원 모델링에 대한 연구가 활발히 진행되고 있는데, 그 중에서 정밀한 DSM 취득이 가능한 LiDAR 자료가 도시지역 건물 3차원 모델링에 가장 유망한 자료이다. 그러나 LiDAR 자료만을 이용할 경우에는 선형화 과정 등의 수작업이 많이 들어가고, 주관적인 재구성과정이 들어가야 하는 문제점이 있다. 따라서 본 연구에서는 수치지도를 LiDAR 자료와 같이 이용하여 건물 3차원 모델링시 작업자의 수동적인 과정을 단축하였다. 항공사진과 해석도화기를 이용한 정확도 평가 결과 1:5,000 수치지도 정확도 규정을 만족하는 도시지역 건물 3차원 모델링이 가능하였고, 비교적 자동화된 공정을 이루었다.

In the construction of high-rise residential buildings in which the finishing works are done repetitively in each housing unit, the construction period and cost can be reduced, while maintaining the quality, if the work process is properly managed in order for the resources to be input continuously. Time management methods such as the Bar Chart, CPM and LOB are not appropriate, due to the difficulties involved in the diagraming of repetitive works and applying them to the project. The Tact method also has difficulties in maintaining a constant work flow and needs significant effort and cooperation from the subcontractors to allocate the resources consistently. Partitioning, base works for finishing, floor mortar plastering and the final finishing work are done sequentially in residential buildings projects, and there are many repetitive activities which differ in terms of the work method, work area and productivity. If these repetitive activities are synchronized or converged toward the last work area, the goal of process management can be achieved effectively. Therefore, a process planning method for the finishing works of residential building projects is proposed, which takes into consideration elements, such as the sequential relation between the activities in each housing unit and classification of repetitive works in terms of their management method, work area and production rate, for the continuous input of resources into the housing units.

Three-dimensional modeling of cities in the real-world is an essential task for city planning and decision-making. And many three-dimensional city models are being developed with the development of wireless Internet and location-based services that identify the location of users and provide the information increases for consumers. Especially, in case of urban areas of Korea, indoor space modeling as well as outdoor is needed due to the high-rise buildings densities. Also location-based services should be provided through spatial analysis such as the shortest path based on a space model. Many studies of three-dimensional city models are feature models. In a feature model, space is represented by combining primitives, and relationships among spaces are represented only if shared primitives are detected. So relationships between complex three-dimensional objects in space is difficult to be defined through the feature models. In this study, Navigable space-relation model(NSRM) is developed, which is topological data model for efficient representation of spatial relationships between objects based on the network structure.

1990년대 '4 3그룹'은 한국 건축을 주도해온 소장파 그룹이다. 개발 열풍에 '건축'에 대한 국민적 인식과 토양이 빈약한 시대, 이들은 '메시지가 있는 건축'을 내세우며 건축계 담론을 주도했다. 4 3그룹에서 김인철 건축사는 전통에 바탕을 둔 공간철학인 '없음'을 화두로 작업해왔다. 이는 '형태는 기능에 따른다'라는 루이스 설리번의 말을 '형태는 공간을 따른다'로 바꾸어 우리 건축의 정체성을 확인하려는 것이다. 그는 건축평론가들 사이에서 건축의 본질을 추구하는 자세가 자연스럽고, 집요하며 진정성이 있다는 평을 듣는다. 머물러있지 않고 지속적인 실험 탐구로 변화하며, 건축을 다루는 손맛이 좋은 것으로 유명하다. 그런 그가 올 4월 행복도시의 건축을 집행하는 행정중심복합도시건설청 총괄건축가에 선임됐다. 최근 그의 사무소로 찾아가 근황과 총괄건축가로서 원칙, 그리고 앞으로의 계획 등을 들어봤다.

This study analyzed the components contained in the pine needles of first and second-year-olds to analyze the factors that the in vivo content of inorganic elements affects the sex determination of pine trees. In response, the plan for pine tree plant and maintenance was intended to be presented in consideration of the reproductive environment and physiological characteristics. The results are as follows. First, last year, when there were many encyclopedias, the analyzed N(%) content was found to be high. The nitrogen content of the previous year's soil was found to affect the production of the spheres the following year. This is believed to be possible to reduce the rate of Pine pollen produced in the new plant in the following year through a dispute over quality consumption in the spring of the previous year. Second, the weapons elements involved in the Pine cones and the generation of the Pine pollen in the new plant appeared to be P(%), K(%), Ca(%), and Fe(%). However, the nutrients from the previous year's leaves of Ca(%) and Fe(%) were found to have a low influence on the sex determination of first-year pine trees. Because Ca(%) and Fe(%) are not able to move nutrients accumulated in aging organs due to the nature of the components, feeding nutrients in the fall when the growth of the previous year's branches is reduced is expected to affect oral generation. Third, pine trees are extremely positive and Pine pollen is related to the time of the northeast wind. Therefore, it is believed that it would be good to be located in the northern direction, where the sunlight is good, in an outdoor space. In addition, it is important to use vaginal consumer products in spring and carry out a quarrel involving Mg and Fe during fall to reduce the effect of the Pine pollen, which is an outdoor plant. This is an important part of maintaining and managing pine trees in outdoor spaces as well as the sex determination of pine trees. This study suggested that plant planning, which derives the correlation between pine inorganic element content on sexual determination and takes into account the physiological characteristics of pine trees, is an important issue in the creation of outdoor space. Follow-up research on other factors affecting pine tree sex determination is expected.
