The aim of this interdisciplinary study is to understand the relationship between the social behavior patterns and space elements, specially micro-housing sociological point of view. It analyzed korean typical floorplans in the apartment housing, focused on the 4-criteria contact or isolation between the individual persons, communication between the generations, hierarchy of the gender and socialization with neighbourhood. It determinate concrete space elements involved correspondent factors with users' social behavior. By reviewing those factors found, it is suggested also the planning concept, that response users' social orientation. As the practical alternatives, some prototypes have been developed not only for improvement of housing plans, but also for resonable housing supply and sustainable usage.

Generally, berth assignment problem has conflicting factors according to the interested parties. In the view of shipping company, it is desirable that berth assignment is made according to the order of arrival. But in the view of port operator, it is better to be assigned regardless the order of arrival to promote the efficiency of berth operation. Thus, it is necessary to establish berth assignment planning which reflects both of interests in a practical situation. This paper aims to develop a reasonable berth assignment algorithm in a container terminal by considering the prescribed factors, and suggests three types of models minimizing the objective functions such as total port staying time, total mooring time and total maximum mooring time by using MPS concept. These models are formulated by 0-1 integer programming and min-max type function, but as the number of variables increases, an optimal solution cannot be achieved easily within a desired computational time. Thus, to tackle this problem this paper proposes a heuristic algorithm, and also the heuristic algorithm proposed in this paper is verified through the several examples.

It is hoped that this paper may be a contribution to the solution of further problems arising from the gap between theory and practice. The practical cases in the application of PERT.CPM in Korea was investigated and studied. And the results are presented. These examinations of the actual cases led to a conclusion that in order to apply effectively PERT.CPM and to diminish the gap between the planning and actuality, emphasis must be given to the second factors rather than the first one shown on the network diagram, in the course of the control of the work. These second factors are PERT Status Analysis Report, PERT Emergency and PERT Count Down etc. They are the best methods that can eliminate difficult elements on the critical path, by making the maximum use of slack time.

The studies on eco-village have been focused on the notion of the village and methods to construct it. However, there haven't been enough studies to research changes of the village derived from dwellers of the village. This fact is being one of reasons to deliver many constructions of Eco-Villages being out of balance. Though the dweller is practical user of the village, planning methods concerning user's opinion are not used and even devaluated in the comparison to methods at the beginning of the planning. Thus, this study began to research dwellers' consciousness for Eco-Village and point out problems which can be happen in real life of Eco-Village.

Preproject phase is an important but often ignored research area in information systems field although it has an undeniable importance for successful project. The purpose of this study is to identify factors affecting project performance in preproject phase and to find empirically critical factors among them. After deriving 9 factors through literature review including clear project definition, project leader position, staffing efforts, preproject team expertise, preproject knowledge scope, preproject partnering, top-management support, resource sufficiency, and project climate, the study investigate the influence of those factors on project performance. The study results reveal that clear project definition, project climate, resource sufficiency, pre-project knowledge scope, project leader position have significant impact on project process satisfaction, a measure of project performance, but the other factors do not. Based on the empirical results, the study discuss academic and practical implications.

The purpose of this study was to establish the more rational and practical basic theory for the landscape planning in the aparment complex. In this study, the actual conditions of exterior space, the residens' satisfaction degree and the correlation between exterior space and the residents' satisfaction defree were investigated and analyzed on the 13apartment complexes in Taegu City. Through the statistical analysis, the main results were obtained as fellows : It was found that the size of green area ratio in the apartment complexes were in the order of Jugong Apt. (Korean Housing Corporation), Siyoung Apt. (City Operation), Minyoung high-rise Apt. (Private Business) and Minyoung low-rise Apt. (Private Business) complex. The highest ratio of footway and Parking area were shown in Minyoung high-rise Apt. complex. The important factors at the exterior space of apartment complex were composed by 6 major factors, importance degrees of which are Visual, Practical, Convenient, Sentimental, Recreational and Spatial factors for teenagers in orders. The residents' satisfaction degrees to the exterior space were highly correlated with the spatil organization, size of green area and quantity of trees, view, management situation, defensibility of outside noise, rest place, water landscapings by turns. In order to get more than the average satisfaction degree 18 exterior space, the green area should be occupied by 35% of the apartment complex area and more than 76% of the green area (i. e. 16% of the apartment complex area) should be planted with trees. In the Taegu City regulation, the ratio of tree composition is proposed for only the number of tree. But it was shown that the satifaction degree are more correlated with the species and afforestation of trees than the nuts her of trees in this study. therefore, the species of tree and the afforestation of tree should be considered when the landscape planning of the apartment complex begins. It was found that the ratio of afforestation to make the more desirable exterior space In the apartment complex shoule be 8 to 2 in the ratio of arbor to shrub. It was also required that 30 species of arbor and 15 species of shrub should be planted for the more desirable landscape of the apartment complex.

There is an increase in interest and investment in high-rise housing as it is perceived to be a new value-added market in the construction industry. In constructing a high-rise housing, the finishing works are executed in accompaniment with many other activities that are progressed repeatedly and spontaneously on each floor. It was reported that the duration of finishing works differs according to the management ability of the executing company and has a significant effect on the entire project duration. We suggest a need to concentrate on important management factors by analyzing the factors affecting the productivity of finishing works based on the site characteristics in high-rise housing. There are various complex productivity-affecting factors including the technical factors involved in planning and managing the processes of finishing works. From the viewpoint of planning and management factors, the importance of productivity-affecting factors was analyzed using the Analytic Hierarchy Process (AHP). A continuous examination of the management of high-importance factors will make it possible to improve productivity by enhancing the understanding of productivity-affecting factors of finishing works and suggesting a practical management direction.

The residents, living in multi-family housing, prefer to have healthy and natural outdoor environmental for better human and environment quality. Thus, providing the high qulity of amenity has become a popular word in site planning and housing developments field. However, the scope and definition of amenity have not yet clearly identified and it becomes and issue in planning and development field. The purpose of this study isto examine and to evaluate the amenity and its implicationi for site planning so that analysis methods such as to interview and survey with residents were carried out. The results of this study are summarized below; The amenity of residential environment means total environmental quality to the residents in a broad sense. Abundent green environment would be very important factor to increase the amenity of residential environment so that the expansion of green field would improve the quality of multifamily housing. The expansion of green environment and biotope was the most important factor to increase the symbiosis system between residents and outdoor environment. And the amenity should be conformed to the certain standand of environmental quality and the high quality of amenity would be increased significantly in the future for residental developments. Thus, it should be accomplished by preparing practical methods in means of discriminative strategy products planning principle.
