  • The model plant, Arabidopsis thaliana is the subject of an international genome research project. Massive doses of ionizing radiation have been shown to induce physiological changes in plants. The wild-type (Ler) Arabidopsis plants were irradiated with 100 Gy and 800 Gy of gamma-ray. Gibberellin (GA) affects developmental processes and responses according to the various environment conditions in diverse plant. The 13 GA isomers were analyzed at vegetative (VE) and reproductive (RE) stages by HPLC. Total GA contents were reduced with the increase in radiation doses at VE and RE stages. Specifically, levels of GA3, GA4, GA12, and GA34 were significantly reduced with the increase of radiation doses. Oligonucleotide microarrays analysis was performed with Arabidopsis plants at different developmental stages and doses of gamma-ray. Through the microarray data, we isolated 41 genes related to GA biosynthesis and signaling transduction. Expression of these genes was also decreased as the reduction of GA contents. Interestingly, in GA signaling related gene expression, gibberellin-responsive protein, putative (At2g18420) was down-regulated at VE and RE stages. Myb21 (At3g27810), Myb24 (At5g40350), and Myb57 (At3g01530) was down-regulated at RE stage. In GA biosynthesis related gene expression, YAP169 (At5g07200) and GA20ox2 (At5g51810) were down-regulated at 100 Gy treatment of VE stage and 800 Gy treatment of RE stage in cytoplasm, respectively. However, exceptively, GA3ox2 (At1g80340) was up-regulated at 100 Gy treatment of RE stage in cytoplasm. In this study, the wild type (Ler) Arabidopsis plants showed differences in response with development stage at the various doses of gamma-rays. GA contents change was reported in gamma irradiated plant.

  • This paper overviews the historical background and development of applied nutrition and community nutrition in Korea. The nutrition studies in the early years focused on animal experiments, human metabolism, and food analysis and therefore were limited to classrooms and research laboratories in universities without spreading into the lives of people. Korean specialists trained through the UN International Course of Applied Nutrition initiated the Applied Nutrition Program (ANP) in Korea in the 1960s. The ANP in Korea was effectively implemented until 1986 with support from UNICEF, FAO, and WHO as a national project to improve the nutrition and health of rural residents. With economic development and urbanization in Korea, the rural-focusing ANP was re-born to a more extended version with the name of "Community Nutrition", targeting the nutrition and health of the entire Korean population. Scholarly associations including the Korean Society of Community Nutrition established in 1995 have significantly contributed to the development of Community Nutrition in Korea and are expected to continue to work for a better connection between nutrition and health promotion.

  • Purpose - This paper attempts to identify the problems and limitations of a market maintenance project conducted according to the 「Special Act for the Development of Traditional Markets and Shopping Street」 and to present a revised direction for the special law and lay the groundwork for market maintenance projects to be promoted smoothly. Research design, data, and methodology - The revised direction for the legislation and the proposal were written based on an investigation of the problems and the legal system, and proposed measures for market maintenance operation and system improvements to derive the improvements needed for market maintenance projects. Results - A market maintenance project has been conducted as a means to reinvigorate traditional markets that are economically depressed, and to revive the local economy. It was largely conducted in the form of reconstruction and redevelopment and represents the interests of landowners and merchants. Thus, it is most likely to contribute to the gradual disappearance of traditional markets. First, as part of a market maintenance project, many companies are building multipurpose buildings or high-rise residential buildings to increase profits. In these high-rise buildings, they can raise rents, which may not be affordable for some existing small businesses. To solve such problems, the large-scale store registration requirement needs to be relaxed or abolished once the market maintenance project is completed. If the large-scale store registration requirement is to be abolished, the term 'large retail store' should be changed in the 「Special Act for the Development of Traditional Markets and Shopping Street」. After registration, the Small and Medium Business Administration should train merchants, offer consultations, and support events, to the extent that the existing traditional market management modernization project permits, and further continue to manage and support its ongoing activities. However, unless large-scale store registration is abolished, adding an exception clause in the special law to relax large-scale store registration criteria, and permitting changes to building use is another option. At the end of a market maintenance project, empty stores should be purchased by the Small and Medium Business Administration, and local government, etc., at the actual construction cost, to utilize them as public rental shopping areas, which in turn may be re-utilized as a temporary market for another market maintenance project. The second problem in market maintenance projects is merchant-protection. Currently, the special law prescribes that a temporary market be created for merchants to conduct business during the rental period of a market maintenance project. Conclusions - In reality, a market maintenance project is conducted usually in big metropolitan cities with 500,000 residents or more. The main building type created under these projects is a multipurpose building. For this reason, it is very difficult to secure a location for a temporary market in the surrounding area of such a project. To solve this problem, this study suggests 'public rental shopping areas' as mentioned above.

  • As the number of aid projects for farming village has been increased, rural amenity is being emphasized. On the contrary, we have a shortfall in excavation and utilization of great resources due to the utilization limit for resources in each village and similarity with the resources from other areas. Thus, we're trying to investigate the ways to make effective use of excellent amenities for farming village development project. In this study, through the principal component analysis, we tried to extract the key factors from the selected areas and examine actual application case of resources. This study categorized the key resource into the big class such as development, farming, nature and experiencing and target areas were categorized into two main classes accordingly. The finding shows 5 example places selected as great areas are taking advantage of extracted excellent resources and 2 target areas are also utilizing enough of excellent resources of each area. Not only limit of used items, subjective view of researcher and resources of each area but also participatory intention of residents and management ways should be additionally considered for another study from now on.

  • In urban planning, road facility is used not only for the transportation purpose but also for the utility line space purpose such as electrical, gas, tele communication, heating, water, sewer, and so on. However, since these utilities are built by many different groups, it becomes very difficult to communicate each other. Delay in one party can cause another party's schedule delay but they don't commuicate often. Also, some delay in utility work can cause frequent pavement cut. And, this will impact on construction cost, schedule delay, low quality, user complain and cost. This study developed spatiotemporal decision model to prevent prequent utility cut for mega project such as new urban development project. In addition, this study developed utility cut management system to manage utility cut schedule under pavement. Finally, developed system was applied to new urban development project and verified there effectiveness.

  • With expansion of modern cities, a huge number of old industrial facilities have been abandoned. Thus, in the development of ecological city, this study aims to conclude on these old facilities and their ecological landscape designs by analyzing successful cases. The approaches adopted are as follows. Starting with literature review, whereby old industrial facility's definition and developing process are pinpointed, the paper studies representative cases with reuse and re-development theories of ecological design for old industrial facilities, of which renovation types, reuse effects, and design features are particularly examined. Case studies also demonstrate considerations in ecological reuse designs, such as ecological restoration, energy conservation, rainwater collection, and utmost pollution reduction, etc. However, technology, environment and circumstance differences determine that each design project requires concrete analysis, which should also be considered in future ecological design for old industrial facilities.
