  • The conventional markets in small towns have showed a different trend, compared with those of urban district. As the conventional markets, which are located in urban districts, are being depressed, those in small towns are being activated by each local government. The activation of conventional market is being recognized as an important means for developing communities, and the project for fostering conventional market is being competitively carried out by each local government. The active center of conventional market is constituted centering on the central area of the market. However, in case of the small towns' conventional markets, it is known that the market site, which is secured at market day, heavily influences on the central area. Thus, in order that the small towns' conventional markets may be activated, securing territories of conventional markets and market site should be considered. Altogether, in order to activate the conventional markets, some conclusions were derived as follows: Expanding market site through improving the usability of space by territories, Controlling peddlers by territories and balancing business items, Amplifying the convenient facilities for users, Securing and improving the central area, Standardizing the facilities that were installed by stores and peddlers.

  • Through the fast economic growth since the 1960s, Korea has experienced various problems on land such as urban sprawl, the rapid increase in land prices, land speculation, privatization of the betterment, and so on. To prevent such problems and to enhance harmonious development and conservation, the National Land Planning and Use Act(NLPUA) was established in 2003. The NLPUA which was revised and combined two existing planning laws i.e. the National Land Use Management Act and Urban Planning Act, has an eye to preventing disorderly spatial development, to pursuing environmentally friendly spatial planning, and to following up planned development in non-urbanized area like rural area. This study aims to discuss what should be considered the pending issues after the application of the NLPUA in rural area. On the basis of reviewing the NLPUA in a viewpoint of the rural planning, this study suggests some improvement policy such as considering various rural conditions, securing excellent agricultural land, applying the District Plan II system effectively, reorganizing the planning administrative, and so on.

  • Apartment houses, the representative type of urban housing, are becoming an important element in Korea urban landscape. In this regard, this study aims to consider landscape in view of city residents reflecting human's visual perceptual characteristic, and in line with this, the urban landscape of apartment houses viewed from the urban center main intersections has been embodied according to the physical components of the intersections, which was followed by preference survey of the city residents, and then based on this, the visual-perceptual characteristics were examined. The findings are as follows: 1. The findings gained from the average of the landscape types indicate that the city residents are more satisfied when the shielding by surrounding buildings is minimized, view securing is relatively good, the whole complex is clearly observed because of its proximity to the visual point, and the view of the complex is well recognized from the focus point. 2. The examination concerning the preferred factors positively evaluated in terms of architectural planning shows that when the complex view is changeable sophisticated, makes the residents feel comfortable with its stable, open plan, and it's in harmony with surroundings, such housing attracts the city residents. 3. In terms of architectural planning factors, it turned out that the complex is more preferred when the visibility of the complex and the scale of surrounding green space are in good condition, and such elements of the complex as the sky line, the overall shape, the elevation, variation of the shape and height are harmonious with one another.

  • Recently, it has been important not only to evaluate environmental effects but also to assess cumulative and comprehensive effects by the development projects. This paper concentrates on temporal and spatial cumulative impacts on Suji district in Yongin, Gyunggi-do. This paper adopted two methods to assess the cumulative impacts. First, it assesses the temporal change of forest patch size and land cover according to the patch size. Second, it compares housing development zones with the neighborhood. The result of the research appears that the damage is very serious, especially in small forest. The Forest area is changed to farm land, most of them become to built-up area later. In addition, it is assessed that the secondary housing development projects did more harm than the initial one. By assessing the cumulative impacts on Suji district, this research suggests to minimize two kinds of solutions : comprehensive environmental assessments in regional unit and regulation on total forest quantity.

  • Recent urban sprawl has destroyed various kinds of green space in tile city. It has affected duality of people's life in the city, as well as urban ecosystem. Recent study shows the possibilities of roofs as green spaces in urban central site where the land costs are generally high. This research focuses on Jung-Gu district in Daegu Metropolitan city as a study area and calculates possible area of green roof using 2002 Autocad program based on aerial photographs and land registration maps. And the purpose of this research is to analyze environmental and economic effects of green roof. The environmental effects are as follows. It is expected that $91,106m^2$ green spaces, 12.13 % of study site, will be added if green roof is performed in the study site. It is assumed that the expanded areas could reduce the highest temperature to $0.5-1.0^{\circ}C$ during the summer in terms of environmental effect. And the following shows the economic effects. If green roof and greening urban central site are created as a same size of $91,106m^2$, it will be expected that the costs of green roof will be much more in-expensive than about 98 billions won. It will be also found that the expense of cooling energy can be saved out about 8 millions won per day in summer, if grass planting is accomplished on the possible areas of green roof in the study site. Therefore, it is desirable to take legal supports such as enacting regulations to activate green roof for more environmental and economic effects. For instance, green roof for public institutions, school and model area selection are desirable method to publicize the effect of greening program for citizen's participation.

  • 도시에 있어서 공원녹지는 도시의 구조적, 사회적 환경을 개선하는 다양한 기능이 있다. 본 연구는 도시의 공원녹지계획이 도시환경의 개선에 관한 연구이다. 지금까지 도시에 있어서 공원녹지계획의 대부분은 녹지의 양의 증대를 목적으로 실시되어 왔다. 그러나 한정된 도시공간에서 공원녹지의 물리적인 확충은 토지의 확보가 어려워 곤란한 것이 현실이다. 그럼으로 본 연구에서는 기존의 공원녹지와 녹지에 대한 이용자평가를 통해 향후 공원녹지계획상의 학문적 근거이론의 확인과 실무적 사례 구축에 기여한다는 의의를 가진다. 본 연구에서는 공원녹지의 구성과 배치특성에 균등배치와 집약배치의 각기 다른 특성을 가진 일본의 타마뉴타운의 두 지구를 선택하여 319명의 주민에게 설문조사를 실시하여 t-검정, 요인분석, 중회귀분석의 통계방법을 활용하여 분석하였다. 연구의 결과로서 공원녹지의 구성과 배치가 다른 두 지구의 만족도평가요인은 차이가 확인되지 않았으나, 각 지구내의 세부평가요인에 있어서는 차이가 확인되었다. 만족도에 영향을 미치는 요인으로는 공원녹지의 질, 주변녹지의 질, 접근성, 차도분리의 요인이 두 지구의 공통요인인 것이 확인되었다. 공원녹지가 집약배치된 지구에서는 만족도평가요인에 있어서 주변녹지의 질이 만족도에 가장 큰 영향을 미치며, 공원녹지가 균등배치된 지구에서는 만족도평가요인에 있어서 공원녹지를 이용하는 보행공간의 차도분리가 만족도에 가장 큰 영향을 미치는 것이 확인되었다.

  • Background: The global burden of cancer is continuously increasing. According to recent report of the National Cancer Registry Programme (NCRP) on time trends it is estimated that future burden of cancer cases for India in 2020 will be 1,320,928. It is well known that knowledge of the incidence of cancer is a fundamental requirement of rational planning and monitoring of cancer control programs. It would help health planners to formulate public health policy if relevant ethnic groups were considered. North East-India alone contains over 160 Scheduled Tribes and 400 other sub-tribal communities and groups, whose cancer incidence rates are high compared to mainland India. As since no previous study was done focusing on ethnicity, the present investigation was performed. Materials and Methods: In this paper PBCR-Guwahati data on all cancer registrations from January 2009 to December 2011 for residents of the Kamrup Urban District, comprising an area of 261.8 sq. km with a total population of 900,518, including individual records with information on sex, age, ethnicity and cancer site are provided. Descriptive statistics including age adjusted rates (AARs) were taken as provided by NCRP. For comparison of proportional incidence ratios (PIR) the Student's t test was used, with p<0.05 considered as statistically significant. Results and Conclusions: Differences in leading sites of Kamrup Urban District since from the beginning of the PBCR-Guwahati were revealed among different ethnic groups by this study. The results should help policy makers to formulate different strategies to control the level of burden as well as for treatment planning. This study also suggests that age is an important factor of cancer among different ethnic populations as well as for overall population of Kamrup District of Assam.

  • Objectives: This study identifies the meaning of walking and its facilitating factors and barriers from the perspective of urban walkers in Seoul. Methods: The participants consisted of twelve people who either lived or worked in Gangnam district of Seoul. The study applied the data collection process featured in the photovoice, in which the participants took photographs and shared their stories through focus group interviews. Results: Walking is regarded as one of the easiest types of physical activity. While walking, participants find mental tranquility, communication opportunities, and a chance to step back from their everyday lives. Facilitating factors include: access to walking-friendly venues and attractive surrounding environments; the participant's assimilation into the surrounding area; having the feeling of ease and relaxation; and friends and family to walk together. Barriers consist of physical factors such as street design and the busy urban streets, insensitive traffic and low civic awareness, and personal situational factors. Conclusions: The benefit of walking exceeds beyond those of physical health promotion. Actions to encourage walking in urban areas should address the multiple meanings perceived by their citizens.
