The planting pattern of Seoul street tree could be divided into six patterns, that was, one row, double row, median strip type and bicycle road type. The protection facilities of installed street tree was inadequate, because it was so small and weak. Recently, the growth rate of street tree in Seoul was decreasing because of air pollution. Strong alkali soil proved to be inappropriate for the growth of street tree. Soil hardness of treepit equipped with treegrill was lower than unequipped one. From the analysis of correlation between the growth environments of street tree, we could conclude that the vitality of street tree are proportioned to the distance from the center of Seoul. The way of improvement for physiological growth and increase of street tree were as follows; establishment reform of street facilities, the installation of protection equipment, continuous and systematic management.

Nowadays, the government, nongovernmental organizations, and educational institutions have come up with a variety of policies and objectives which are concerned about the importance of public design in the city. The project for integrated street environment in Sung-Nam at this time has started with the purpose to make the citizens' life safer and wealthier, and the purpose to improve the image of the nation. In the process of modernization, we must realize the overlooked problem(the thoughtless development for the environment and the threatening of the identity about the disagreed value and esthetic sense.) as our problem. We have focused on the suggestion of the road facilities suitable for urbanization which coincides with the quiet city and the global standards rather than pursuing the local growth and meaning. Based on the New Governance Design, we have presented the liberal design process which actively accepts the experts in a variety of fields. With the language of design, 'high-tech, self-restraint, and growth', we have made a homogeneous urban factor which is ideal for time and space.

Air pollutants of concern include traffic-related air pollution, including particulate matter in respirable coarse and fine size fractions. There are no critical studies to date into associations between knowledge, awareness, and attitudes in using proper respiratory masks and prevalence of respiratory symptoms among urban street vendors in Thailand. In this study, we estimated adverse respiratory health outcomes among street vendors, in particular young adults, in Bangkok, Thailand, using a self-report questionnaire. Street vendors, who were not currently smoking and not having known diagnosed respiratory diseases, were recruited. They were selected from selected roadsides at Chong Nonsi, Bangkok. Participants (n = 30) reported having lower respiratory (50%), upper respiratory (37%), and other symptoms (70%). Also, 53% of participants had never used respiratory personal protective equipment (PPE: masks). Among those using PPE, all used masks not proper for particulate matter. Results suggested knowledge, awareness, and attitudes concerning proper PPE use needs to be increased among street vendors in Bangkok, Thailand.

The aim of this study is to find what architectural restoration and street-scaping conservation of early settlement in Virginia, which have processed on the style of 18th centuries. One of the settlements in Virginia was Williamsburg that located in the high land between Jamestown and Yorktown. In 1698, the capital of Virginia was moved from Jamestown for the safer environment. At that time they constructed the town like a small urban that had a straight-lined Duke Glocester Street, Georgian style buildings, and landscapes of 18th centuries. Before 1928 the village was flown into ruins, but Rector of the church, Dr. W.A.R. Goodwin, understood the value of reservation to restore the village as colonial architectural style that has an original figure. John Rockefeller Jr. has taken part in his restoration of colonial style of architecture and culture. This paper surveyed nine cases of buildings and srtreet-scape on Duke Glocester Street. Most of the buildings on the street have a proposition, balance, and equipment of Georgian architectural facade in 18th centuries. The conclusion has three points. First, the Williamsburg has been reserved as an early colonial settlement through the restoration of architecture and street-scape design. Second, main architectural style is a Georgian form that has a balance, proportion, and simplicity of facade. Also new buildings and additions of architecture have to keep 'Design Review Guideline of Colonial Williamsburg' in order to contribute the existing colonial buildings. Third, the main street-scape, Duke Glocester Street shows Georgian architecture and cultural life pattern with tradition.

Recently, improvement of the quality of urban riverscape environment has been emphasized not only by landscape architectural field but also by various professionals in planning and ecology. Regarding to this current movement, the aim of this paper is to highlight major visual elements of riverscape axis as a case study of Shinchon River in Taegu City to suggest some basic guidelines for arranging riverscape in urban area. The study was mainly based on Repertory Grid Development method which was developed in Japan. The method is consist of three steps such as decision of element landscape in study area for slide photos, selection of evaluation items for interview and obstraction of proper evaluation factors. The major findings through this study are as follows; 1) The 12 major visual elements which possibly improve riverscape, based on abstraction of proper evaluation factors, are Dunchi, surface of the water,, equipment of river, buildings near riverside, river vertical and horizontal facilities like bridge, fine view, riverbed, water plant, naturalness, water's edge line, harmony and street trees by order. 2) Total numbers of adjective which describe 12 common factors are 25, such as clean, open, stable, quiet, comfortable, friendly, bright, natural etc. In addition, Dunchi was described 337 times by various adjectives, surface of the water was 200 times and arrangement of river was 146 times which is similar result with the order of 12 influential common factors. 3) Therefore, Dunchi, surface of the water and equipment of river are three most important factors which could create better riverscape. These three factors implies us how we supply good quality of urban river environment for the urban residents.

The purpose of this study is to measure some physical environmental factors and to doucument students' perceptions of them. 11 middle schools in Cheju City were divided into four areas according to their locations and two schools were selected for the study. 144 thirteen-year-old students in two middle school in a overcrowded area in Cheju City-one middle school building is insulated and the other is not insulated-were taken for the questionnaire survey. The finding of the study are as follows: 1) The classrooms were not equipped with any heating equipment. The buildings are not insulated well. As a result, the room temperature was much lower(12.9-16.2℃) than comfortable indoor temperature in winter(21.5-24.5℃). The classroom were found to be colder(12.9-16.2℃) than usual pleasant indoor temperature(21.5-24.5℃) in winter. 2) The classroom were so far from the street(20m) that there was little noise from traffic. Nevertheless, the noise level was higher(62.5-66.2 dB(A), when the windows were open; 51.7-62.8dB(A), when closed than the noise tolerance level specified in the Environment Protection Laws(50.0dB(A)). 3) As for the visual environment, the location of classroom, the adequate sun exposure, and the total states of windows in classrooms influenced on the illuminance. While standard indoor illuminance is 300 Lux, the classrooms facing south had illuminance of 231 Lux, from day light: and the ones facing west, 380 Lux. 4) Students generally found other aspects of the physical environment of their classrooms unsatisfactory. Chalk dust was generated to a serious extent near the main chalkboard(0.25mg/㎥) of classrooms.

As the customer's interest for sidewalk block in the street or apartment complex is increasing, the materials of block which had been a concrete block exclusively are varied to clay paver, native rock and wood etc. Especially, the sales volume of clay paver which is environment-friendly and ergonomic is dramatically increasing every year with two digits growth rate, however, many problems like "Edge Cracking" "Freezing Breakage" "Bending Breakage" "Joint Gap" are happening frequently within a couple of hours after installation due to the durabilities. Because of the characteristics of Ceramic products, clay pavers are very easy to be broken when they are bumped against each other. In addition, they are relatively fragile by a freezing expansion breakage when exposed to water due to hydrophilic property as well as the intensity and absorptance of the products are varied with small difference from the production process such as production equipment and process control. Therefore, it costs a lot of money to repair the breakdown unless production and installation is carried out according to the strict criteria of the quality control. In this study, the symptoms of breakdown frequently happened in clay paver are classified by each type and finally the solution for this problem in the production of brick, installation and criteria of quality control through compressive strength and absorptance test is suggested.
