This tudy is to survey and analysis the water quality phase of Agricultural reservoirs through the case study of 18 reservoirs in Kyungpook Province in preparation for prevention disasters from the environmental hazards such as water pollutions. In these cases, the most hazardous pollution acts were Domestic animals excrements firstly, Human living wastge water secondly, Tourist resort sewage and Fertilize waste etc. in regular sequences. In the analysed results, pH, EC, BOD, DO, Cu, Ph, Cd were less than standard values recommended by the Environmental Authority and so they were estimated in scope of the safety value respectively. But few of factors being gradually closed with the hazardous point in the few places. At present, the hazardous environmental acts originated from the Domestic animals ex-crements, Human living waste water and Fertilize waste etc. in case the agricultural reservoirs, have to strongly be improved much better than before and prepared safety conditions for the rural living and agricultural life sciences.

Recently, Rural tourism in China is developing rapidly, however, the rural tourism remains unsatisfactory due to ignoring the landscape aspect which is considered as an integral part for rural tourism. Therefore, we aim to investigate the effect of the landscape elements on vitalization of rural tourism by evaluation of the landscape elements. To this end, we made a questionnaire survery concerning importance and satisfaction of landscape elements through factor analysis, and clamp IPA analysis. As the result, 1) Regional product, safety facilities and public parking lots are the primary considerations as primary factor. 2)Traffic facilities and accommodation should reflect regional characteristics; Garbage collection facility, food and beverage facilities, network and electricity facility should be rectified and maintained; Regaining the original nature characteristics of river and lake, Securing the integrity of the visual appreciation by shelter landscape for Sewage Purification. Our study results may provide a basic reference for the development and management of rural tourism attractions in China.

The purpose of this study is to investigate the influence of the Korean Wave on Chinese tourism to South Korea through a behavioral analysis of Chinese tourists in the general group package tours. China suppressed the needs of the Chinese people's geographical movement and imposed restrictions on information about the outside world with the use of a policy of "closure" for a long time. But since reforms and open-door policies were introduced in China, especially in the context of relaxation of control policies over Chinese outbound tourism after the mid-1990's, more and more Chinese make trips abroad including visits to South Korea. In this situation, the recent Korean Wave(especially, drama/film) describes the Korean national image by forming a bridge between fiction and reality and plays a pivotal role in broadening or reconstructing the geographical imagination of the Chinese people who have been historically isolated from the outside world. Although Chinese have imagined the Korean nationscape on the basis of geopolitical or economic factors in the past, they have currently broadened or reconstructed their geographical imagination to include socio-cultural factors related closely to the Korean way of life due to the recent Korean Wave. This newly constructed geographical imagination led by the Korean Wave functions as an important pulling factor in Chinese destination choices, affecting Chinese tourists' motivation formation and the recommendation of main attractions. The more influential the Korean Wave is on their destination choice, the more the respondents select the cultural factors in both their motivation for tourism to South Korea and their recommendations of tourism attractions to other people. Through the analysis results of both satisfaction and intention to revisit, the more influential the Korean Wave is on their destination choice, the higher is the degree of both satisfaction and intention to revisit. In other words, although Chinese tourism to South Korea is chiefly in the general group package tours, Chinese tourists who are influenced by Korean Wave on their destination choice have more attachment to(or affection for) Korea as a tourism destination. This result suggests that the Korean Wave affects qualitative change - that is, change of attitude - as well as quantitative change in Chinese demand for tourism to South Korea.

해안을 따라 인구밀도가 증가하고 임해지역공단 등 산업시설이 밀집하여 처리되지 않은 하 폐수가 증가하고 있다. 특히, 최근엔 필리핀 보라카이와 같이 관광 위락시설에 의한 하수가 대량으로 발생하고 있다. 또한, 세계적으로 거의 모든 국가의 주요 해안도시는 이러한 도시하수를 바다로 방류하고 있다. 현재로선 이러한 하 폐수의 처리는 바다의 자정능력(self-purification capacity) 한계를 고려한 하수의 해양으로의 방류가 최선의 방법으로 판단된다. 현재 국내에서는 지역에 따른 배출허용기준에 따라 하수의 처리수 방류가 규제되고 있지만, 확산영역에 대한 법적 기준치는 제시되지 않고 있으며, 인근에 위치한 권리자들과의 이해관계 해결에만 몰두하고 있는 실정이다. 또한 확산영향예측이 원역 해석모형(Far Field analysis model)에 의해 수행되기 때문에 근역(Near Field)에서의 영향을 간과하고 있다고 판단된다. 따라서 금회 연구에서는 기존 연구결과를 기준하여 특정해역에 대한 원역과 근역 해석에 따른 확산영향 예측을 수행하고 그 결과를 비교하여 앞으로의 해석방법을 제시하고자 한다.

A number of ocean outfalls are located around coastal area over the United States and discharge primary treated effluent into deep water for efficient wastewater treatment. Two of them, the Sand Island and Honouliuli municipal wastewater outfalls, are located on the south coast of Oahu. There have been growing interests about the plume dynamics around the ocean outfalls since plume discharged from the multiport diffuser may have significant impacts on coastal communities and immediate consequence on public health. Among the studies of plume dynamics performed in the vicinity of both outfalls, Project MB-4 in the Mamala Bay Study recently made with the funding in the $ 9 million amount statistically dealt with the near-field behavior of the plumes at the Sand Island and Honouliuli outfalls. However, Project MB-4 predicted much higher surfacing frequency than the realistic value obtained by model studies by Oceanit Laboratories, Inc.. It is suggested that improvements should be made in the application of the plume model to more simulate the actual discharge characteristics and ocean conditions. In this study, it has been recommended that input parameters in plume models reflect realistic density profile over the entire water column since. in the previous Mamala Bay Study, the density profiles were measured at 5m depth increments extending from 13 to 63 m depth (the density profile on the upper portion of water column was not included, Roberts 1995). It is proved that the density stratification is the important parameter for the submergence of the plume. In this study, as one of the important parameters, plume rise and initial dilution reflecting the density profile over the entire water column have been taken into account for more reliable plume behavior description.

The purpose of this study is to investigate the wise use and the management of intertidal environment. For tills purpose, we selected the Kanghwa island mudflat which is one of the most important intertidal region in Korea peninsula. The main research method is surface sediment and several map analysis. The results are as follows. (1) The study area is worldwide coastal wetland in view of ecology and geomorphology. But most of the salt marsh has been reclaimed since Japanese colonial period, the study area is mainly composed of mudflat. (2) The mean tidal regime of study area is 7.3m. From this tidal regime, the study area is subdivided into four distinct areas: the high intertidal area the middle intertidal area the low intertidal area and the shallow sea area terrestrial area near mudflat. (3) The mean particle size of surface sediment is sand 41.5%, silt 47.3%, clay 11.2%. This particle size pattern indicates the ecological characteristics of surface sediment of the study area. The proportion of clay is increasing to the open sea. (5) The pursuit of the wise use and the management must be implemented by the consideration of not only ecologic and sedimentary characteristics but also of the eco-tour site plan. And the entire use and management subject is different in each area.
