Much has been made of the changes over time to apartment complexes during the era of rapid development in Korea. This study aimed at analyzing the chronological changes since the 1970s in the laws and regulations governing outdoor space and the residents' appreciation of outdoor space in Daejeon's apartment complexes. The results of this study can be summarized as follows: 1. Similar changes can be found throughout Daejeon's apartment complexes. As time has passed, the building-to-land ratio and the floor-to-land ratio have deceased. The high density trend of apartment complexes has continued until very recently. 2. Although residents' satisfaction with outdoor space around apartments has improved, land for athletic and commercial spaces still remains at its lowest level. Therefore, these kinds of spaces need improvement. 3. Comparing the characteristics of outdoor space in apartment complexes from the 1980s to present indicates that current apartment residents are much more satisfied with the outdoor space, but are conscious of the lack of adequate facilities for the elderly and the handicapped people, and of the hiか density of their apartment complexes. Therefore, these essential consciousness should also be further improved. 4. The residents are gradually becoming aware of changes to the outdoor space that have occurred over time in the apartment complexes, such as in the areas allowed to parking, pedestrians, and athletics. 5. These chronological changes relate to the residents' interest in the changes that have occurred to the outdoor space, especially the convenience of parking, the color of the buildings, the form of the buildings, and the shape of the roofs.

The present study deals with the investigation about the improvement of performance of tidal stream turbine blade (HAT) with tip rake. HAT impeller has sometimes experienced noise and vibration by Tip vortex which causes even erosion and severe efficiency loss to the blade, The newly proposed tip rake impeller can make the tip vortex week compared with a normal impeller by preventing the three dimensional effect at tip region. In order to find out the optimum rake impeller, three cases have been designed and the performance of the designed rake impellers has been validated by the commercial CFD code(Fluent). The efficiency of optimized rake impeller was up to 4.6% higher than the conventional impeller. The more parametric study for high efficiency and good cavitation performance is expected to be conducted in a near future.

This study aims to examine at the garden characteristics of salt merchant in Yangzhou, China during the Ming and Qing Dynasties, I looked at the background of garden formation through the literature. In addition, analyzed the garden design method and components of salt merchants. The results were as follows; First, the Yangzhou area in the past has achieved cultural and economic development with the establishment of the ancient Grand Canal. Salt merchants accumulated wealth through trade, and created many gardens under the background of securing materials for create garden through trade, forming political forces through the cultivation of students, and inflow of foreign cultures. Second, salt merchants in Yangzhou asked garden experts to design and create the garden as a place for exchange and relaxation. Also, through the production of landscape changes using Gasan(假山) and a long corridor(長廊), clear classification of spaces using architectural elements, and the placement of buildings in scenic areas adjacent to the water, the gardens with practical and aesthetic functions were owned. Third, the gardens of Yangzhou Salt Merchants have a building-oriented commercial space on the front, and a garden-centered design characteristic on the back. The garden of the commercial zone was built in a simple form using pots, oddly shaped stone, bamboo and fence patterns in the remained space, focusing on the front of the building. The garden at the back formed a curved waterway connected to the canal is refracted across the garden. The garden also features piled stones(疊石), stone bridges and ship-shaped stone building(石舫). In addition, the design reflected the introduction of trees that take into account the climate and color contrast of Yangzhou province, pavement of various materials and patterns.

In this research, we have calculated characteristics of wave-piercing high-speed planing hull, by using a RANS solver and overset grid method, for comparing with experimental measurements of that and simulating with several appendages, since the computed results of commercial CFD code look reasonable for the prediction of the performances of planing hulls on calm water in planing conditions. As a result, it is confirmed that the dynamic instability phenomena in pitch and heave motions (porpoising) occurred after a certain $Fn_V$, and effectively suppressed using some of appendages, especially the 0.5L spray rail is suppressed to 24-55 % in the pitch motion and 33-55 % in the heave motion. In spray phenomenon, 1L hard chine suppress spray effectively and it is effective to set the angle of appendages to be less than $0^{\circ}$ in order to suppress wave.

This article explores an extended sense of autonomy in contemporary architecture activated through the practice of fashion, by taking architect Rem Koolhaas' work Prada Epicenter in New York as a case. In doing so, it argues that throughout the work Koolhaas sets up a world in which the corporate and the individual are entangled together in complex ways. Instead of considering Prada Epicenter to be the exemplar illustrating that the global company-Prada-institutionalizes the designed commercial space in a top-down manner, this article claims that such a space imbricates a multiplicity of meaning that is generated at the intersections of the local and the global, the ordinary and the spectacular, and the individual and the institutional. In this respect French philosopher Gilles Lipovetsky's fashion theory works as a critical point: his claim that the ambivalence of fashion-both as corporate power and individual freedom-is a threshold encouraging us to better understand the operativity of late capitalism in daily life is extended to Koolhaas' case. In other words, Koolhaas' Prada Epicenter brings forth possibilities that the ostensibly technocratic and institutionalized space in fact works as a resillient field where senses of individual autonomy arise in the aid of corporative practice of branding.

The area to be surveyed is the three-seat of Myeon office in Hwasun-gun, Jeollanam-do, where population is declining. Satisfaction with the use of local residents of rural central areas providing life services in the back area was identified, focusing on sustainable development and the compact cities. Based on the results of the study, the recommendations are as follows. First, the local spaces to be surveyed need a shift to a walk-centered choice and social structure, not a must-oriented, activity-centric structure. This not only improves the neighborhood of rural areas, but also increases the frequency of pedestrian exchange and helps keep the community afloat. Second, it could enhance the convenience of residents by reviving stocks in existing commercial areas and integrating public services. Finally, it has the effect of taking care of the socially disadvantaged and immigrants in terms of space welfare, and securing jobs through locally customized community businesses.

Purpose: As the concerns for the environment are gradually prioritized, increasing interests of environment-friendly buildings are drawn. Numerous researches about healthcare buildings have been performed however, they were mainly focused on convenience or healing condition for medical treatments. The hospitals consume energy and generate $CO_2$ as twice as the residential or commercial buildings do. Various green building certification systems are globally arranged. But, it isn't easy to find certification criteria for the green hospital besides the US and UK's ones which are specially designed to evaluate environment-friendly medical buildings(Lim&Yoo, 2010). Methods: In this study, we investigates current conditions of Tokyo Regional hospitals in environment-friendly standpoint and also investigates the foreign certification criteria and systems for the green healthcare building and finds the possibility to apply them to Korean one. Results: Through this study, we found that the Tokyo regional hospitals can be environmentally improved by management plans and programs. Implications: Based on this analysis, Korean Green Building Certification for healthcare facilities will be developed in near future.

The methods of landuse change detection have been used with the algorithm of GIS (Geographic Information System). It is used for the Environmental Planning. Ultimately, it is useful to establish environment management system in landscape architecture. As one of environmental elements, the landuse is repeatedly being changed by the interaction of natural and social environments. In addition, the landuse change shows a tendency to certain characteristic. However, the data of analysis environment system are too broad to access the practical use. Therefore, the possibility of using the method of GIS has been increasing. This study is to make the prediction model by using the interpolation of GRASS version 4.1.5 and to consider about a tendency for each element in landuse change of HAKONE national park. The results of study explain as below : 1. The natural forest and the meadow have a larger tendency of decrease. 2. The area of golf club and facility land has not been changed and the some other areas have been changed to the commercial forest. 3. However, because of the natural forest preservation plan since 1970, the destruction shows comprehensively a tendency of decrease.
