  • This paper deals with "Citizens Organization" and "Citizen Participation" to the process of the regional planning and design not only in urban areas but also in rural residential areas with regard to the range of topics, such as its planning, partnership, environmental study, exchange, training of talented persons and NPO. Even though many attempts on this issue have been developed in various part of Japan, I examine in this essay especially the case of citizens in Hyogo Prefecture. As regards a case in urban areas the various movements set after Great Hanshin and Awaji Earthquake are introduced. As a case in rural residential areas with abundant nature, the activities of "Tamba-no-Mori"in Tamba District and a concept for "the Idyllic Landscape Museum" in North Harima district are introduced.

  • The growth and hole formation of Ulva australis were examined at seven coastal areas of Korea between July and August, 2013. Animal species and weight growing on the Ulva fronds were estimated at Haseom, Pohang, and Woedo. The effects of wave exposure on the morphological features and residential animals of Ulva fronds were investigated at wave-exposed and sheltered sites of Seongsan on October 19, 2013. U. australis had different frond areas ($82-665cm^2$), hole areas ($2.5-6.3cm^2$), and hole numbers (9.8-41.3 holes) at the seven sites. Within $0.1m^2$ of Ulva frond, hole areas ranged from 0.37 to $5.94cm^2$, and between 4.9 and 36.2 holes were observed. Fourteen residential animal species were observed at the three evaluated sites, 75.0 (Haseom) to 408.7 individuals $100g^{-1}$ Ulva (Pohang) per site. The dominant residential species at each site differed with Amphithoe sp. at Haseom, Monodonta spp. at Pohang, and Pagurus sp. at Woedo. The growth (frond area, wet weight) and hole number of Ulva fronds, and the number of residential animals were significantly greater in samples collected from the sheltered shore than the wave-exposed shore of Seongsan. The present results showed U. australis grew well at sheltered shores and had more holes on the fronds due to abundance of residential animals. The dominant residential animals (crabs, gammaridea, and snails) were similar in the Ulva populations of sheltered and wave-exposed shores, but greater species diversity was observed at the exposed shore (18 species ver. 11 species). In conclusion, U. australis is a keystone species providing habitat to various invertebrates and frond holes are positively correlated to the number of residential animals.

  • The purpose of this study is to classify the types of street parking in low-rise residential areas. First of all, prior research was reviewed to examine the background of occurance and the process of change of low-rise residential areas. and derive factors that affect the street environment. Next, based on the selection criteria, the residential area of Bangi 2-dong, Songpa-gu was selected as the site of the case and the status analysis was conducted on streets, buildings, and on-road parking. The summary of the results is on-road parking usually occurs on residential streets where social consensus is difficult to reach, suggesting that alternatives to on-road parking in residential areas are needed. Based on the results of the previous analysis, street types were classified considering the characteristics of streets, structures and street parking. Then, the characteristics of each type of street were analyzed and implication for improving the street environment were suggested. In addition, the results of the classification of street types confirmed that different street parking occurred depending on the width of the street and the use of the lower floors, even if it was the same area, and that a solution was needed accordingly.

  • Wind environment in urban residential areas is an important index to consider when evaluating the living environment. However, due to the complexity of the flow field in residential areas, it is difficult to specify the correct inflow boundary conditions in the large eddy simulation (LES). In this paper, the weighted amplitude wave superposition (WAWS) is adopted to simulate the fluctuating velocity data, which satisfies the desired target wind field. The fluctuating velocity data are given to the inlet boundary of the LES by developing an UDF script, which is implemented into the FLUENT. Then, two numerical models - the empty numerical wind tunnel model and the numerical wind tunnel model with spires and roughness elements are established based on the wind tunnel experiment to verify the present method. Finally, the turbulence generation approach presented in this paper is used to carry out a numerical simulation on the wind environment in an urban residential area in Lisbon. The computational results are compared with the wind tunnel experimental data, showing that the numerical results in the LES have a good agreement with the experimental results, and the simulated flow field with the inlet fluctuations can generate a reasonable turbulent wind field. It also shows that strong wind velocities and turbulent kinetic energy occur at the passageways, which may affect the comfort of people in the residential neighborhood, and the small wind velocities and vortexes appear at the leeward corners of buildings, which may affect the spreading of the pollutants.

  • This study was carried out to investigate the heavy metal distributions of soils in the vicinity of Shi-Hwa industrial complex region, where the air pollutants from industrial area could affect the soil environment of near residential and green areas. The ranges of contents of As, Cd, Co, Cr, Cu, Hg, Ni, Pb and Zn in soils were 0.58~3.81, ND~0.91, 0.15~6.33, ND~l.86, 0.14~110.27, ND~l.17, 0.04~10.59, 1.16~86.48 and 1.83~212.65 mg/kg, respectively. For all industrial, residential and green areas, the heavy metal contents were much lower than the standard of Korean Soil Environmental Preservation Act or the critical concentration which phytotoxicity is considered to be possible. Mean values of contents of As were similar in industrial, residential and green areas. However, the mean values of contents of Cd and Cr in industrial area were higher 10 and 5 times than those in residential and green area, respectively. And also the mean values of contents of Co, Cu, Hg, Ni, Pb and Zn in industrial area were higher 2~3 times than those in residential and green area.

  • In order to develop a manual of residential alterations for the physically disabled, this case study was accomplished to analyze and evaluate residential environments and residential alterations for physically disabled women. Twenty-nine physically disabled women in Seoul and Kyunggi areas were the subjects of this study. With the evaluation checklist on physical environments of their housing, data on general characteristics of wall, floor, and all features and equipments and spaces of bedroom, kitchen, bathroom, living mom, entrance and balcony were gathered. Also, data on residential alterations were gathered through personal interviews. The data were collected from July 18th to July 25th in 2000. Frequency, percentage, and mean were used to analyze the data. In kitchen, small space, hee space under the sink and heights of the lower cabinets were not properly provided. In bathroom, door width, direction of opening door, adjustable height of shower, level difference, clear space for wheelchair user, and storage place were not appropriate to the disabled. Kitchen and bathroom showed high frequencies of alteration. But most of the subjects were not satisfied with the alterations of their housing. They also wanted to alter these two spaces in the future. In order to after their housing effectively appropriate information of the residential alterations was needed. If a guide or manual book for residential alterations was provided, the physically disabled people will more easily after their housing for safe and independent life.

  • As a household's residential location is closely related to its workplace and place of education, the urban exodus of city dwellers changes their ways of commuting to workplace and attending school. This paper examines the influence of urban exodus on the change of a way of life through relations between residential location and modes of commuting. Despite moving to the countryside, exurban migrants still want to experience rural health without abandoning the city lifestyle. However, they are faced with various difficulties in commuting to workplace and attending school, because suburban and exurban areas have poor accessibility to the central city. In order to overcome these problems, most of them choose "the residential segmentation of the family" through which the head of the family commutes to the city from his or her family home in exurban areas and children go to school from their second home in the central city, or try "to link commuting to workplace with attending school".

  • Korea is quickly transforming into an aging society. As a reaction to the accelerated aging society in recent years, there is a growing need to introduce sustainable housing policies and strategies for aging society. The main purpose of this study is to explore where people want to live after retirement. Especially, this study focuses on the residential environment such as housing types, residential location, and living environment. The main findings are as follows. First, people preferred living in a sububan-style housing in the suburban or rural areas to living in a city-style housing in the urban areas. Second, people have a strong preference for the importance of convenience in using natural environment, medical service, and cultural facilities. Third, the family life style has been changed from children-oriented life style to couple-oriented life style by showing that people like to stay with a spouse rather than with their children after retirement.
