For a systematic research of the history of Chinese roadside trees, this study analyzed various ancient writings of China according to following topics; the philosophical backgrounds and diverse species of Chinese roadside trees in different periods, as well as the management systems and existent remains of ancient Chinese roadside trees. The analyses draw the following conclusion. First, the thoughts from Lao-tzu, Chuang-tzu, Mo-tzu, Mencius and Guan-tzu from Hundred Schools of Thought of Warring States Period had laid certain impact on the fundamental attitude of the Chinese roadside tree management system. Secondly, various and different species of Roadside Trees were planted from each time period: amongst all, Willow trees were the most common, and Pine trees to be the next common. Besides, fruit trees such as peach trees and plum trees had been largely selected as roadside trees from the Zhou dynasty to the Ming dynasty. Thirdly, the names of roadside trees and the government officials who managed the roadside trees were different in each era. Fourthly, the oldest existent remain of roadside trees in China, which dates back over 2000 years, is located in Jiange Cuiyun Corridor of Sichuan province.

The objective of this paper is to present a methodology for the classification of spatial patterns considering the parameters of urban form which play a significant role in the formation of the urban climate. The urban morphological parameters, i.e. building coverage, impervious pavement, vegetation, water, farmland and landuse types were used to classify the spatial patterns by a K-means cluster analysis. And the presented methodology was applied on Changwon city, South Korea. According to the results of cluster analysis, the total spatial patterns were classified as 24 patterns. First of all, The spatial patterns(A-1, A-2, A-3, B-1, B-2, B-3, C-1, C-2, C-3, D-1, D-2, D-3, E-1, E-2, E-3, F-1, F-2, F-3, G-1, G-2, G-3), which distributed in the rural area and the suburban area, can have the positive impacts of cold air generation and wind corridor on an urban climate environment, were distributed in the rural area. On the other hand, the spatial patterns of the downtown area including A-4, B-4, C-4 and D-4 are expected to have the negative impacts on urban climate owing to the of artificial heat emission or the wind flow obstruction. Finally, it will require the future research to analysis the climatic properties according to the same spatial patterns by the field survey.

This study was conducted to develop an ecological park planning model to enhance the functions of habitats and ecological corridors in Green Belt Areas, because changing policies have resulted in the degredation of the Green Belts due to progressive fragmentation of ecosystems. The principal outcome of the study is to plan an ecological park model through the restoration of habitats. In order to evaluate the capacity of the model to enhance the ecological functions of habitats and ecological corridors in Green Belt Areas, a simulation of habitats was carried out in the Sungnam-Yusoo region. The model was developed via following steps: 1. Selection of candidate sites and selection of the study site by analyzing development factors; 2. Selection of target species that can represent the habitat at the site; 3. Analysis of the site's suitability index for the target species; 4. Establishment of a conceptual plan to enhance and expand the currently produced suitability index; 5. Creation of a master plan based on the conceptual plan; and 6. Evaluation of the enhanced and expanded suitability index of the site. The study showed that the Habitat Unit (HU) of Rana coreana, which was selected as the target species of the study, increased from $28,044m^2$(3.6%) to $224,352m^2$(28.8%), and the HU of the site as the ecological corridor for wild animals increased from $4,674m^2$(0.6%) to $152,684m^2$(19.6%). The study results show that the ecological deficits of the Green Belt Area can be overcome by enhancing the ecological functions of the region, which should be beneficial. The model could be utilized for effective enhancement and management of other Green Belt Areas.

The aim of this study is to analyze the organization of ithe internal space of Usonian houses that were designed by Frank Lloyd Wright between the 1930s and the 1950s. The Space Syntax Program was used to analyze spatial structure of these Usonian houses. The research range has been done on 9 case studies of Usonian house floor plans, which were designed from the 1930s to the 1950s. The shape of unit floor plans of Usonian house are usually in various L types, - types and transformed types etc.. The research results are as follows : 1) The service space(Kitchen etc.)is located at the center of house and it plays a role in separating the private space(bedroom etc.) and public space(living room etc.). 2) All of the bedrooms of Usonian houses have common characteristic : they are connected by a galley(corridor). 3) The organization of the inside space of most of these houses showed a tendency segregation space. 4) The galley inside space of Usonian house is the most integrated space in the house 5) The living room of the 1930s houses was analyzed as segregation space but it of 1940s and 1950s houses was analyzed as integration space 6) Although bedrooms are connected by galley, which is the highest integrated space of the inside space, this space is analyzed as a segregated space.

This paper presents a two-phase quantitative framework to aid the decision making process for effective selection of an efficient freight logistics hub from 8 alternatives in Thailand on the North-South economic corridor. Phase 1 employs both multiple regression and Pearson Feature selection to find the important criteria, as defined by logistics hub score, and to reduce number of criteria by eliminating the less important criteria. The result of Pearson Feature selection indicated that only 5 of 15 criteria affected the logistics hub score. Moreover, Genetic Algorithm (GA) was constructed from original 15 criteria data set to find the relationship between logistics criteria and freight logistics hub score. As a result, the statistical tools are provided the same 5 important criteria, affecting logistics hub score from GA, and data mining tool. Phase 2 performs the fuzzy stochastic AHP analysis with the five important criteria. This approach could help to gain insight into how the imprecision in judgment ratios may affect their alternatives toward the best solution and how the best alternative may be identified with certain confidence. The main objective of the paper is to find the best alternative for selecting freight logistics hub under proper criteria. The experimental results show that by using this approach, Chiang Mai province is the best place with the confidence interval 95%.

The Korea Water Resources Corporation(KOWACO) proposed bidding for an alternative design for Hwabuk Multi-purpose Dam in March of 2004. The site is located in Hakseong-ri, Goro-myeon, Gunwi-gun, Gyeongsangbuk-do and has adrainage area of $87.52km^2$. The purpose of this project is to establish an environmentally friendly plan for minimizing the damage that was caused by the construction of the Hwabuk Multi-purpose Dam. The design principle of KOWACO was the restoration of the natural environment, a harmonious landscape, and the creation of a space of regional and local culture. The basic concept of this project involves an ecological-restoration axis and a functional-connection axis. The site is divided into four spaces: (1) the space of memory and symbol, (2) the space of nature and ecology, (3) the space of regional and local culture, and (4) the space of the regional economy. There are four sub-spaces in the space of memory and symbol: the track forest, the time forest, the memory room, and the sun plaza. There are three sub-spaces in the space of nature and ecology: the habitat of aquatic birds, the wind forest, and the eco-corridor. There are five themed parks in the space of regional and local culture: the culture and relic room, the wildflower garden, the ecological pond, the insect observation park, and the pyogo maze. There are three areas in the space of the regional economy: the forest pension, the waterside pension, and the community center, as Dungdungi village was reorganized to serve as a lodging complex. These themed parks, working together, can offer an effective space for nature, culture, rest, and experience.

An early stage of general hospital in Korea was the quantitative growth period. Remodeling has been required to meet the increasing medical demands. To accept the change of paradigm and management operation method, remodeling occurred from the 20th century. Remodeling plans are difficult to define the direction of the detailed plan due to various factors in the beginning of the construction, Therefore, it is necessary to analyze the possibility and limitation of a feasible remodeling plan of general hospitals through the comparison of existing hospital before remodeling and after the remodeling takes effect. A comparison of the researched hospital's blue prints before and after the remodeling and recently built hospital's blue print, analyzed characteristic of the space variation by the remodeling. The purpose of research is to confirm a possibility and limitation of remodeling of general hospitals comparing with merits and faults of extension, reconstruction, and construction. In conclusion, the area of remodeling hospitals increase mostly medical department(ward, outpatient department, inpatient department) and subsidiary facilities, but the area of ward and inpatient department are less than the new hospitals. Especially, public area is greatly increased by the diversification of corridor function. Also, remodeling hospitals represent a limitation to plan departments in need of equipment-intensive space. To address this problem, expansion space is used mainly with inpatient department and existing space is placed mainly with low-impact department by equipment ; outpatient department, administration department.

Association of South East Asian Nations(ASEAN) has recently decided to develop ASEAN Highway Network to connect member countries by road in an attempt to achieve a goal of closer economic integration in the region. This entailed the necessity to newly construct or upgrade some 5,481 km of road sections to make ASEAN Highway Network functional. This study offers haw we can prioritize development of these road sections using the Analytic Hierarchy Process. Particularly, it shows how individual road sections can be prioritized considering the importance of corridor or road group where the individual road section lies. It also develops how values of different evaluation criteria can be compared in the same scale. This new approach can be useful in prioritizing highway development in such cases where candidate road sections are widely scattered around the region, so detailed benefit and cost analysis is practically too demanding to carry out.
