  • Excessive acceleration experienced at the top floors in a building during wind storms affect the serviceability of the building with respect to occupant comfort and discomfort. Tuned liquid damper (TLD) and multiple tuned liquid damper (MTLD), which are passive control devices consisting of a rigid tank filled with liquid, are used to suppress vibration of structures. These TLD and MTLD offer several potential advantages-low costs, easy installation in existing structures and effectiveness even for small-amplitude vibrations. This study carries out a theoretical estimation of the most effective damping ratios that can be achieved by TLD and MTLD. Damping by TLD an MTLD reduced the frequency response of high-rise buildings by approximately 40% in urban and suburban areas.

  • In this study, we surveyed the influence of IOA (iodoacetamide) and media upon protoplast fusion for the efficient production of the somatic hybrid among S. sisymbriifolium and other Solanum species (S. intergrifolium and S. toxicarium). Regardless of a breed, as the IOA concentration increases, the cell division tends to decrease. As the influence of the media on the colony formation, we could get 5 colonies from the fusion of S. sisymbriifolium and IOA-treated S. integrifolium protoplast, but none was observed in other fusions. As a result of analyzing their IDH isozyme, we found a somatic hybrid in 2 objects.

  • The main purpose of this study is to suggest fundamental materials and a guideline for design through grouping of the users' use route patterns and analyzing determinants to choose those route patterns in urban parks. Study sites were Jungang, Dlseong, and Beomeo park, where located Taegu city-Key results obtained through a series of investigation were as follows : When Users come in and out urban parks, most orientations of their use routes were counterclockwise, and not in such cases, greatly affected by facilities arrangement. There were a large number of users in the main route placed the principal facilities. Users' use route patterns were grouped by their characteristics, which were circulation, semi-circulation, irregular, and piston type. And all the types except piston type can be subdivided into spoon and loope type. Factors analysis to the types produced five meaningful patterns of variables. Five factors were named as dimension of characteristics : Park composition factor, facilities use factor, users' personal factor, park use behavioral factor, routes choice factor.

  • ^x Good Planning, design, and maintenance will be the product of a Process which considers both the nature of man and the nature of nature. Recentry, we emphasize how social and psycological theory, behavioral studios, and community participation may contribute to practical decision making and to the development of appropriate form for human use at all scales of Landscape Architecture. The main purpose of this study was to develop more rational and user oriented theory of urban park planning, design, and maintenance in terms of social - behavioral approach. Study sites were Jungang, Dalsung, Duryu, and Apsan park, where were located Daegu city. In this study, user satisfaction determinants of each park, which were useful for park planning, design and maintenance, were discovered. Privacy and territoriality were examined as an important factors for design a park road examined as an important factors to design a Path and a comfortable space in urban park.

  • In order to answer the challenge that development gave to environment, Chinese cities are making up and putting into effect the green space system planning. The planning main keys are: set down standards and scope of green space; bring the characteristics of every types of green space in to full play and made into basic units of the system; formed powerful links of the system; make full use of the natural system of city, constituted the urban and countryside as a organic whole green space system, therefore give full play their function and ecological effect. In fact, this green space system is a complex system. It is the main body of city ecological system, a main container of the citizen activities of leisure and recreation and a leading factor for making characteristic city landscape. Therefore it is a system carrying city's environment sustainable development.

  • Full-scale ferro-concrete building technology came was introduced in Japan in Meiji $35{\sim}40(1902{\sim}1907)$ and heralding the beginning of urban modernization. On the roofs of these new architectural constructions, full-scale rooftop gardens were also developed. We consider that gardens established on the roofs of hotel and department stores created a new, modernized garden culture, which greatly influenced the early modern urban culture of Japan, the drama of which it conceived based on the impression in a rooftop garden is made. In this paper, we discuss the influence of Meiji-Era cultural and technological advances on rooftop gardens constructed during the Taisho $Era(1912{\sim}1926)$, as represented by the gardens of Kobe's Oriental Hotel, Tokyo's Mitsukoshi Department Store and Shimonoseki City's Akita Company. Photographic and print sources are utilized to analyze the design features and temporal changes of these pioneering rooftop gardens, as well as their influence on urban culture.

  • The making of mountains and waters are recognized as essential to traditional Chinese landscapes and it is this concept that guided the Beijing Olympic Landscape, "Axis to Nature". The Olympic landscape extends the central axis of Beijing north until it is punctuated by the Forest Park Hill and dissipated by Forest Park Lake. Traditional landscape gardens, paintings, and poetry were researched and the plan assessed by eminent scholars and experts to conceive and construct an ecological park that features unique design and traditional Chinese landscape art.

  • Suburban green lands play an indispensable role in maintaining norma! operation of the urban ecosystem. However, the suburban green lands are also the most fragile and easily disturbed places since they are close to the city edges. The suburban green lands of Kunming city show diversified forms, and it would be difficult to avoid taking part of those green areas in the rapidly expanding urban construction. To better preserve and utilize the suburban green lands of Kunming, it is vitally important to base ourselves on the practical situation of Kunming and take into full consideration the features of urban expansion and suburban green lands, so as to optimize the structures of suburban green lands, scientifically plan and readjust the remaining suburban green lands, and enhance the comprehensive efficiency of the daily dwindling suburban green lands in protecting and regulating the ecosystem, beautifying the environment and outputting economic benefits. Suburban green lands in some specialized areas must be put under strict protection.
