수자원의 정량적인 계획과 관리를 위해서는 정확하고 신뢰성 높은 유량 자료가 필수적이다. 이에 따라 최근에 초음파유량계와 유속지수법 등의 실시간 유량 측정 방법이 도입되고 있다. 이러한 방법들은 단면의 일부분에서 측정한 유속을 이용하여 전체 단면의 유량을 산정하고 있으므로 하천 단면의 2차원적 유속분포에 대한 합리적이고 이론적인 기초가 필요하다. 본 연구에서는 Chiu(1987, 1988)가 제안한 2차원 유속분포식을 자연하천에 적용하고 ADCP 실측 자

The promotion of walking and bicycling is recently a hot topic in the urban planning and design field. Many planners have already examined the many components of the land use-transportation connection and built environment-physical activity link. A rapidly growing area of urban form research is to measure the level of walkability in urban environments. With this background, this research conducted a preliminary study to develop the evaluation indicators of pedestrian environments. Based on the literature reviews on walking or pedestrian environments, we proposed the seventeen indicators related with pedestrian facilities, road attributes and walking environment. We also performed a questionary survey to evaluate the satisfaction of their neighborhood pedestrian environments for 302 randomly selected adults living in the City of Changwon, Gyeongsangnam-do. Finally, this research provided the valid model to evaluate the effects of physical environmental factors on the walking satisfaction using factor analysis and multiple regression analysis.

With treatment of Kitosan, Wood vinegear and EM(effective microoganism) which farmers call it as substance in fertilizing, conditioning and disease control ubstances, authors in vestigated on microorganisms change in soil and ealy growth characteristics of tomato. The results were summarized as follows : Among foliar application of kitosan, wood vinegear and EM(effective microoganism) treatments diluted by chitosan 500 times solution level was effective considering growth of tomato as compared other dilutions and control plot. Change of microorganism number in the soil for cultivation of tomato was increased with microorganism treatment plot as compared with control plot. Specially chitosan 500 times solution level showes the most significant effect.

This study was surveyed and analyzed in 2005 year for environmentally-friendly rice’s production 78 farmers in korea. The major results was as follows : The average age of farmers were 54 years old, the experiences of environmentallyfriendly rice’s production farms was 7.4 years, the cultivated scales of environmentally-friendly rice’s production was 3.4ha. The 74%’s Farmers of all unified rice"s breeds for rice’s production of high-grade in quality, the ranking of rice’s breeds selection were the high-grade rice’s breeds of government＞japan rice’s breeds. The control of damage by blight and insects were needed environmentally-friendly control, the endured study of this control were very important. To cut down cost of the environmentally-friendly rice for income security of farmers and sustenance of farming will. To receive reasonable price of environmentally-friendly rice, the brand image were raised to consumers, the variety and miniaturization of rice packaging unit were needed in view of consumers. In addition to must be campaigns of publicity through the press and event to consumers, were managed the exchange of rice goods and exchanged e-mail together consumers for the maintenance of confidence. To drive direct marketing between environmentally-friendly rice farmers and consumers through experiential marketing, to diversify the marketing channel. To strengthen public relations at regional level and relationship at the consumers.

Proper management of small rural watershed is important since it does affect water quality improvement of larger scale watershed. Therefore, effective small watershed management guideline including participatory program of local people is required to achieve water environment improvement. Feasibility of water quality goal, short and long-term watershed management plan and funding sources were investigated by field monitoring of Hampyungchun watershed which has characteristics of rural stream, and literature review. The relevant parties and their roles fer watershed management were identified and suggested. A hybrid model, that is mixture of government driven model and NGO model, is recommended for watershed management organization in this study.

This paper aims to find the characteristics of concentration distribution of coastal urban air pollutants. For this purpose, It was used the daily meteorological data and the hourly concentration data for O3 and NO2 in Busan metropolitan city from 1994 to 1996. It was investigated the annual and monthly distribution of ozone and nitrogen dioxide concentration at each site in Busan, and also investigated the characteristics of concentration change of air pollutants with time under the sea breeze. As a results, the concentration of nitrogen dioxide and ozone tend to be increased every year and nitrogen dioxide concentration is higher than ozone concentration at all sites in Busan. The concentration of ozone is high in summer season and low in winter season, but the concentration of nitrogen dioxide have a reversed trend. The monthly peak concentration of ozone occurred in April and September, while the monthly minimum concentration of nitrogen dioxide occurred in August. Their trend were identified by sites near the coastline than sites stands apart from the coastline. The sea breeze occurred annual mean 81 day in Busan from 1994 to 1996. The main wind direction of sea breeze was classified into southwesterly and southeasterly. In case of southwesterly, It was pronounced the south wind and southwest wind. In case of southeasterly, the occurrence frequency of east wind was high. Especially, the concentrations of urban air pollutants, such as ozone and nitrogen dioxide, were high on time which the sea breeze flow, and the areas that ozone concentration was high moved from outside part to central part of city with time. In costal urban such as Busan, the wind direction of sea breeze is influenced the change of ozone and nitrogen dioxide concentration on time which the sea breeze flow at each site and also influenced the change of air pollutants concentration of sites on the pathway of sea breeze.
