The widespread of IT technology caused a remarkable change in many industries and the construction industry is also one of them being influenced in the form of CIC(Computer Integrated Construction) and BIM(Building Information Modeling). Construction projects have many participants from various disciplines involved throughout the entire process. Therefore the success of the project greatly depend on the efficiency of decision-making using the information generated from each process stage. Looking from this aspect, the greatest potential value lies in the planning and pre-design stage when considering the construction life cycle. In this paper, we propose a project on developing a 3D object oriented simulation system for supporting the pre design phase. We define the needs for such system through previous case studies and suggest a to be process model. Finally we anticipate the effects that the project will eventually contribute to the construction industry.

The digital network system is one of the most important features in the resent hospital buildings. This study is to lay out a guideline of architectural planning according to the hospitals with digital network system. First, this study develops the concept of hospital building digital network system and reports the survey results of domestic general hospitals for this matter. Required spaces by digital network system in general hospital are classified into two categories. One is equipment room, main equipment room and a telecommunication closet, to accommodate network facilities. The other is the spaces related with medical information, medical archives and the department of radiology, because digital network system makes a change the form and use of information. In result, this study proposes models for each equipment room and raises the possibility of size change of information-spaces.

The architectural design of student circulation space has a pronounced influence on the educational function of a school building. Recent curriculum and new teaching methods have required the sufficient space provided for circulation and various circulation spaces in a school building, such as elevator, pilotis, bridge, atrium, deck, lobby and locker room. However excessive circulation space is wasteful form the standpoint of both initial investment and operation. This study aims to investigate new circulation patterns and functions, and to propose the adequate size in planning a school corridor. For this purpose, it explores the recent trends of the corridor planning represented in the excellent school facilities in 2002. and analyzes the newly-added functions In the school corridor : architectural in-between space, dwelling space for ordinary activities, space for educational media and auxiliary learning space. This research recommends that the corridor width be carefully planned according to the supposed functions in order to achieve the efficiency in the design of school facilities.

Disassembly of products at their end-of-life (EOL) is a prerequisite for recycling or remanufacturing, since most products should be disassembled before being recycled or remanufactured as secondary parts or materials. In disassembly sequence planning of EOL products, considered are the uncertainty issues, i.e., defective parts or joints in an incoming product, disassembly damage, and imprecise net profits and costs. The paper deals with the problem of determining the disassembly level and corresponding sequence, with the objective of maximizing the overall profit under uncertainties in disassembly cost and/or revenue. The solution is represented as the longest path on a directed acyclic graph where parameter (arc length) uncertainties are modeled in the form of intervals. And, a heuristic algorithm is developed to find a path with the minimum worst case regret, since the problem is NP-hard. Computational experiments are carried out to show the performance of the proposed algorithm compared with the mixed integer programming model and Conde's heuristic algorithm.

The constructability of Formwork has a importantly influence on the duration and cost in a construction project. However, the existing studies on the formwork are mainly focused on a method of construction. Although a layout planning of forms, especially, is an important factors affecting the constructability and cost, it is done by engineers empirically and intuitionally after completion of structure design. Therefore this study suggest a decision support model for optimal formwork layout model based on the rearrangement of structural members by using Genetic Algorithm to improve constructability of formwork.

In less favored areas, it is getting more difficult to manage Satoyama according to aging of rural residents and depopulation. Some support of urban residents are necessary for management of Satoyama. In this paper, the role of Satoyama management activities was clarified through the analysis of the feature of activities for managing Satoyama. The questionnaire and interview surveys were done in order to clarify the actual conditions for management of Satoyama and activities of urban residents who are participating in NPO in Hyogo Prefecture. The results of analysis are as follows. (1)The form of rural-urban exchange in Satoyama is different in each Satoyama. (2)The urban residents are contributing to the region very much on both sides of the manager and the visitor in Satoyama. (3)Many urban residents visit Satoyama for the purpose of enjoying the variety of nature and culture programs in rural area. (4)There are some urban residents who participate in activities for managing Satoyama even if Satoyama is far from their residence. So it is important for rural residents to arrange the condition that they can visit rural area without difficulty.

Recently, it is demanded to study about agri-environmental indicators including rural landscape indicators. However, there are deficiency to establish the policy of int landscape. This is the base study for the policy decision or management for conservation of agricultural landscape or rural landscape. The objectives of this study were 1) to analyze the supporting elements in the foreign policies, 2) to analyze the agricultural landscape elements and visual values in the field and 3) to make the classification form about the agricultural landscape. And finally, this study suggests the management guides for the conservation of agricultural landscape according to the teleological measures. Through this results, it would be expected to develop the efficient policy of rural landscape such as the direct payment program for rural landscape conservation.

Air Rights techniques, including floor-area ratio (FAR) transfers, FAR bonuses, and FAR storage, have been widely applied among skyscraper constructions in New York City for profit maximization goals. Since 1916, air rights regulations in New York zoning system have been revised and improved over the years to cater the urban development needs of different periods, and they also result in typical skyscraper block typologies. This research firstly performed spatial overlay analysis to reveal the spatial correlation between skyscraper blocks and air rights application blocks; secondly, Spacematrix parameters and cluster analysis are applied to divide the skyscraper urban block of New York City into four categories. Compared with air rights application data, the research attempts to illustrate how various air rights techniques have acted on the formation and evolution of skyscraper block typologies in the pre-1916, 1916-1961, 1961-2010, and 2010-present periods respectively, in order to reveal the relationship between public policies and urban morphology in a broader sense and also provide references for policy making in future.
