The ecosystem model was applied to estimate the regional distribution of the net production(or consumption) of phytoplankton and the net uptake(or regeneration) rate of nutrients in Masan Bay for scenario analysis to find a proper management plan. At the surface level, net production of phytoplankton is 200 mgC/㎡/day at the entrance of the bay, and 400∼1000 mgC/㎡/day at the center of the bay. The inner area of the bay showed more than 2000 mgC/㎡/day. All areas of the bottom level have a net consumption, with the center of the bottom level showing more than 600 mgC/㎡/day. For dissolved inorganic nitrogen, the results showed a net uptake rate of 100∼900 mg/㎡/day at the surface level. It showed that the net regeneration is above 50 mg/㎡/day at the bottom level. For dissolved inorganic phosphorus, the net uptake rate showed 10.0∼80.0 mg/㎡/day at the surface level, and the regeneration rate showed 0∼20.5 mg/㎡/day at the bottom level. Therefore, in order to control the water quality in Masan Bay, it is important to consider the re-supplement of nutrients regenerated in the water column.

The factors to limit interior circumstance and the expression of the space start In the point how to provide the order in the interior space according to the intention of design. The controlling of the natural and artificial surroundings should be focused by synthesizing and analyzing the condition of circumstance, function, and emotion to provide the comfortable room to a customer in a fitness center. A fitness center aiming at the future requires various function according to it's role depending on the change of the social values. In addition, the fitness center reflecting the various regional culture according to the change of values requires the expansion of the cultural and life space. The characteristics of fitness space like this affects the mental effect of a customer with the color and quality of the materials suitable for the characteristics of grouping, continuity, symbolism, and generation as well as the unification in the total design and the simplicity of maintenance and management. The paper aims to extract factors related to the circumstance plan of the interior and to suggest it's application in the interior design. The design applicable to the circumstance plan of the interior will keep changing according to the social change and the change of the understanding along with the factors. The continuous research on the interior circumstance planning of a fitness center could be approach to develop in a systematic method and the paper will be expected to be a little step toward it.

The research was conducted to quantify farm and household characteristics of sheep farmers, evaluate farmer access to and the effectiveness of livestock services in sheep farming areas, and examine regional constraints to improving sheep productivity and profitability in Nepal. A rapid diagnostic socioeconomic survey of 200 sheep farmers was carried out in 1996 and all four ecological regions (Trans-Himalayan, Mountains, Hills and Terai), each with a distinct local sheep breed, were represented in the survey. Six major constraints were identified: (a) poor performance of local sheep breeds, (b) a serious seasonal deficit of pasture and other feed, (c) the lack of an organized market for wool and meat, (d) poor access to agricultural credit, (e) primitive shearing equipment, and (f) an inadequate supply of drinking water for sheep. Strategies to assist farmers develop their sheep management skills, improve access and quality of support services, improved technology adaptable to local conditions and effective linkages with local carpet and meat industry are likely to overcome the constraints and alleviate persistent poverty faced by sheep farmers in Nepal.

The vein necrotic strain of Potato Virus Y (PVY - VN) and black shank (Phyto-phthora parasitica var. nicotianae) are the two major diseases causing severe damages especially in burley tobacco (N. tabacum L.) area in Korea. A new tobacco variety, KB 111, resistant to PVY and black shank disease, was developed by Korea Ginseng & Tobacco Research Institute in 1997. It is a male sterile(MS) F$_1$ hybrid of the cross between MS TC 613 and KB 108. KB 111 was compared to Burley 21 on the agronomic characteristics and disease resistances in performance tests: It possessed upright growth habit and flowered two days later than Burley 21. It was resistant to both PVY and black shank and yielded about 3% more cured leaf than Burley 21, but other characteristics are very simiar to those of Burley 21. The chemical composition and physical properties of the cured leaf of KB 111 were as much acceptable as those of Burley 21 while it produced average yield of good quality leaf and appeared to resistant to PVY and black shank disease on regional farm test in 1998.

Traffic noise is a kind of noise caused by cars, trains and aircraft. Among them, noise produced by cars is the most important factor in cities. According to the National Institute of Environmental Research(NIER)'s survey, Road traffic noise levels in Susan are the highest of all the cities in Korea. So, appropriate measures for road traffic noise reduction is required. For this purpose, the construction of a noise map in Susan will playa vital role. However, road traffic noise formulas are constructed considering regional characteristics such as each country road's environment and vehicle quality. Therefore, prior to constructing a noise map in Susan, examination processes about each formula constituent status and estimation process are required preferentially. In this research, the basic first stage is to estimate Susan's road traffic noise. First, investigate characteristics of each road traffic noise estimate and using this, a noise map is constructed for road traffic noise in Susan. Then the adaptation of a road traffic noise formula is evaluated.

The purpose of this study is to identify specific patterns of Sasimi consumption in Korea using cluster analysis. The data applied in the analysis were collected from five major cities in Korea through telephone interview with trained surveyors. This study investigated three major topics; 1. Korean people prefer to eat Sasimi at the restaurants rather than at-home. 2. The quality of Sasimi is different according to where the eating place is located such as seaside or inland. 3. Determinants of Sasimi Consumption are different according to population characteristics, sex or occupation. The main findings of the study can be summarized as following three points. Firstly, Koreans preferred to eat Sasimi out 83.3% of respondents chose eat-out rather than eat-at-home. These are especially popular with men, 40' years older, self-employed, lived in capital area. Secondly, satisfaction level of Sasimi consumption was good in Choong-Cheung province. Since Chung-Cheong Province was located in the inland, the chance to eat Sasimi is lower than seaside. Thirdly, consuming decision factor of Sashimi was different across groups. None of decision factors take effect on Group 1 while indigenous variable of Sashimi has effect on Group 2 and external variable has effect on Group 3. Therefore, in order to increase Sashimi consumption, it is necessary to at-home consumption of Sashimi should be improved. Moreover, it is necessary to develop marketing strategy which fits in regional characteristics and to have government assistance.

Tall building has some controversial aspects with low carbon city, but it is still a sensible choice for the metropolitan city. This paper aims to develop holistic urban design strategies to minimize impacts on the environment, increase energy efficiency and improve the quality of living in tall building communities by utilizing tall building characteristics. It puts forward the concept of integrated tall building-low carbon community design from the perspective of urban design, and summarizes five core strategies: Temporal state based on energy use, Complementary energy use state based on functions, Spatial state based on regional environment features, Transportation state based on low-carbon lifestyle and Waste utilization state based on tall building characteristics. It also applies the strategies to a practical project. The results show that the proposed urban design strategies are available approaches to mitigate the side effects of tall building on low carbon city.

Elevated linear parks have the potential to support the ecological stability, city amenity, cultural opportunity, and health benefits of urban dwellers; these are increasingly becoming an integral part of the urban infrastructure. Due to structural limitations in space, linear parks need to be planned to increase the value of green space. This study was aimed at advancing urban planning techniques for increasing the value of elevated linear parks, by comparing the Seoullo7017 with the Promenade $plant{\acute{e}}e$ and the Highline. Planning characteristics of these green spaces were analyzed from the perspectives of physical planning factors, amenity values for users, and management systems. Field surveys and virtual tools were used to investigate the current characteristics of these parks, in addition to the literature survey. From the analysis of planning factors, amenity values, and management in the three linear parks, following important recommendations were made in order to promote the values of these parks: (a) diversify planting design for increasing the diversity of green space in a narrow area; (b) bring in various forms of amenities to promote the quality of users' experience; and (c) establish community-based management systems for enhancing regional competitiveness and profit sharing in urban regeneration projects.

This study aimed to analyze the impact of water curtain cultivation in the greenhouse complexes on groundwater's electric conductivity and water temperature. The greenhouse complexes are mainly situated along rivers to secure water resources for water curtain cultivation. We classified the groundwater monitoring well into the greenhouse (riverside) and field cultivation areas (plain) to compare the groundwater impact of water curtain cultivation in the greenhouse complex. The groundwater observation network in Miryang, Gyeongsangnam-do, located downstream of the Nakdong River, was selected for the study area. As a result of analyzing the electric conductivity and water temperature, the following differences were found in the observed characteristics by region. 1) The electric conductivity and water temperature of the riverside area, where the permeability is high and close to rivers, showed a constant pattern of annual changes due to the influence of river flow and precipitation. 2) The flat land in general agricultural areas showed general characteristics of bedrock observation in the case of water temperature. Still, it seemed more affected by the surrounding well's water use and water quality. The electric conductivity did not show any particular trend and was influenced by the surrounding environment according to the location of each point.
