  • The objective of the study is to assess the water quality improvement resulted from the rearrangement of the irrigation water supply systems at Mankyeong River and Ansung Chun basin. There is a mixed type of watershed composed of urban and rural areas in the region. From the water quality analysis, showed high T-N, T-P concentration in Ansung chun and Mankyeong river caused by paddies separated widely around Ansung chun and Mankyeong river and by runoff of the pollution from the Ansung and Jeonju city. but the upstream of the river showed clean water quality, so if we use the upstream water as river maintenance water for water quality improvement, it is expected to be positive effect for rural environmental aspect.

  • The progressive contamination of water resulted from man's activity and the use of fertilizers is not restricted only to surface water, but also the shallow groundwater is affected. This type of groundwater contamination is mainly restricted to areas composed of permeable, nonconsolidated sediments forming a shallow aquifer. The chloride and the sulfate resulted from man's activity and the use of fertilizers were measured to study the variations of the groundwater contamination. In general, (1) When water level rises, the rate of groundwater contamination becomes less and when water level declines, the rate of contamination is increased. (2) The highly contaminated season is the early-summer and the less contaminated season is the winter or after rainy season. (3) The groundwater in weathering zone without covering layer. (4) The degree of contamination of wells is increased with the increase of well depth and lowing the water table, because of increasing contaminated water from enlargement of the area of influence of the well.

  • V. parahaemolyticus is a species of gram- negative asperogenous rod which gives rise to gastroenteritis in man and widely distributed in Korea. In this study, the distribution of V. parahaemolyticus among sea water and various marine products in Inchcon during the period of July 1984 to August 1984 was studied. The following results were obtained: 1. V. parahacmolyticus were isolated from 16(15.4%) of 104 specimens of sea water and various marine products. 8 strains(11.0%) were from fish and marine products 3 (25.0%) from aquarium watar, 3 from chopping board 1 from sea water and 1 from sea water in basin. 2. Among the 14 strains tested, 10 were Kanagawa phenomenon positive and 4 were negative. 3. 16 strains were tested for K antigens and 3 were found to be $K_{17}$, 1 each of $K_{22}, K_{25}, K_{34}$ and $K_{57}$. 7 strains were not agglutinated with any K-type multiserum.

  • Most of the short period waves are blocked by the breakwaters when the short period irregular waves propagate into the ports. However, nonlinear irregular wave numerical experiments show that the long waves generated by the nonlinear interaction is predominant in the port. Seiches phenomenon in Geumjin Fishing Port is very similar to 60 and 300 second harbor oscillations. By arranging the inner breakwater of the proper length in the inside of the port, it is possible to effectively reduce seiches, as well as the short-period wave, and significantly improve the harbor tranquility. In the case of rectangular basin type such as the Geumjin Fishing Port, the multi-directional irregular wave numerical model should be used for the investigation and countermeasures for the harbor tranquility.

  • This paper is aimed at analyzing the soil erosion hazard zone in farm land. RUSLE was used for an analysis of soil erosion amount, and for the spatial data of basin, soil erosion amount was calculated by extracting the respect topography space related factors of RUSLE using DEM, Landuse, Soil map as base map. As a result of analysis on the calculated soil erosion amount according to land use type, it was analyzed that the most soil erosion occurred in orchard area, i.e., 40.08ton/ha/yr at average. It was classified into 5 classes depending on the calculated soil erosion amount. of which Class V was decided as soil erosion hazard zone, and for this area, 72.5ha or so, $2.4\%$ of the entire farm land was assessed as erosion hazard zone.

  • We assessed the physical habitats of Microphysogobio longidorsalis in the Han river basin. Field monitoring was conducted for ecological and habitat conditions for 11 sites from October 2008 to November 2011. Twenty species (50.0%) including M. longidorsalis and Zacco koreanus were found endemic out of the 40 species in 10 families sampled during this study period. The most frequently found species was Z. platypus (26.2%) followed by Z. koreanus (17.7%), Coreoleuciscus splendidus (14.0%) and M. longidorsalis (13.4%). For M. longidorsalis, total fist length showing the highest number of samples were 8~10 cm (50.9%). the favored habitat conditions were estimated to be 0.4~0.5 m (56.1%) for water depth, 0.2~0.9 m/s (90.4%) for flow velocity, sand (0.1~1.0 mm)~cobbles (100.0~300.0 mm)(94.5%) for substrate size and run (60.2%) for habitat type, respectively.

  • The study on bathroom plan for the elderly who use wheelchair has been done continuously. However, the elderly's behaviour at the bathroom and consideration for the caregiver has been underestimated. In this perspective, the purpose of this study is to find out how much more bathroom size is needed for the elderly who use wheelchair and the caregiver based on their behaviours. The study method is as follows: First, behaviours which occur at bathroom were collected from the previous research. Second, the size needed was calculated based on the elderly and caregiver's movement. Third, the size of bathroom enough for the impaired elderly with caregivers was suggested. The room next to shower booth and bath tub should be expanded for the caregiver. In addition, the room beside the basin should be added as much as $600{\times}600$ to let the caregiver stand and support the elderly when they are needed to wash their hair. As a result, the size of bathroom should be at least planed as follow; $1.3m^2$ more for type A, $1.5m^2$ more for type B, $1.6m^2$ more for type C, and $1.1m^2$ more for type D. As the bathroom is the room that the elderly want to modify for their rest of the lives, the room should be reserved enough from the early stage of design, so that this will make the elderly be possible stay at the place until they want to stay.

  • As changed population structure variously, population decrease is one of the important problem in present urbanization. It resulted decline of the medium-large size housings that increasing of 1-2 person household need the variety of small housing with housing type. This study was researched the Gold-Generation on theme by Gold Miss, Gold Mr. who preferring urban small housings that it analyzed survey of Gold generation who be wanted urban small housing by interior coordination elements. Data to be analyzed that first, Gold Mr. and Miss are preferred two bedroom applied by spatial structure coordination. Especially it is based on the separation between livingroom and bedroom with duplex type which is bathroom formed single unit type(shower/toilet/basin). In interior coordination of spatial elements, Gold Mr. considered the form of kitchen with huge ㄷ type instead of Gold Miss are preferred alpha room or alpha space to use powder room or dress room. Second, In Preference of interior coordination elements, Gold Mr. and Miss are preferred bed-clothes and curtains by fabrics, lighting are hanging and spot lighting, accessories are carpet with rug and porcelains. Color are preferred bright scheme both white and ivory, however preference of furniture is different from Gold Mr. and Gold Miss that Gold Mr. are ordered desk, sofa and shelves but Gold Miss are preferred sofa, bed, and dressing table. It showed between Gold Mr. and Gold Miss are equal needs or differences. It expects the basic research for understanding the interior coordination elements for preference in urban small housing as focused on Gold generation(Gold Miss, Gold Mr.) that they will be applied the interior space on urban small housing.
