빈번한 재난의 발생으로 인해 사회적인 피해가 증가함에 따라 국가에서는 더욱 체계적인 방재시스템을 구축하기 위해 노력하고 있다. 특히, 이를 위해 전자재해지도와 같은 GIS기반의 재난정보시스템을 구축하여 활용하고 있다. 하지만 대부분 특정지역만을 고려하는 독립적인 형태의 데이터체계와 정보제공이 이루어지고 있기 때문에 다른 시스템과의 연계 및 활용측면에서는 취약점을 가진다. 또한, 재난정보서비스를 구축할 경우 데이터의 작업과정이 별도로 필요하기 때문에 많은 시간과 노력이 투입되어야 한다. 따라서 본 논문에서는 재난데이터의 인덱스코드에 대한 연구와 인터넷 포털사이트에서 제공하고 있는 지도 및 마이크로블로그 서비스 활용하여 더욱 신속하고 체계적인 재난정보서비스를 구현하였다. As disaster number increases, governmental institutions is trying to construct effective disaster information system. Especially, most institutions are using disaster information system based on GIS such as electronic disaster map. However, most previous systems have vulnerability when connecting to the another systems because systems consider only specific area and system is independent data structure. Above all things, existing have to put a lot of time and effort because system need direct work course for service. Therefore, this paper implements quick and methodical disaster information service via study of data code and map, microblog service from internet portal site.

As it is forbidden to landfill the organic sludge generatεd in water treaanent plant fÌom 2001, disposal coast of the sludge will be highly incersed. Therεfore, Th.is Srudy was conducred to recyle the sludge of water supply planr as inorganic fertilizer for agriculrural areas and forests using the Chemical and the Hydrothermal methods. As the result, we could manufacture sutiable inorganic ferrilizer, removing organics and harmful heavy metals by the Chemical and the Hydrothermal method. 2001년부터 정수장에서 발생하는유기성오니의 직매립이 금지됨에 따라이의 처리비용이 매우증가할것으로판단 되어 본 연구에서는 정수장 슬러지를 Chemical 및 Hydrothermal 법을사용하여 농업 및 임업용 비료로 재활용 할 수 있는 방법을찾고자진행하였고,그결과두방법 모두유기물및 유해 중금속을제거할수있었으며 안정화된 무기질 비료를 제조할수있었다.

This study is undertaken to find the optimal method to make the decision on the degree of water pollution by comparison of K-WQI, KOE-WQI that is made for index with the water quality index and water quality environment standard of the Frame Act on Environment Policy as the result of survey for water quality reality on the major point of the Yeongsan river from 2002 to 2004. The water quality of major rivers has some differences depending on seasons. however, under the water quality standard by the $BOD_5$ density, most of rivers displayed the water quality level of $II{\sim}III$ grading, and on K-WQI that is classified by indexing for 10 categories of pH, DO, $BOD_5,\;COD,\;SS,\;T-N,\;NH_3-N,\;NO_{3^-}$ N, T-P, and E-Coli and classified into 5 groups from 100 points to 40 points, they displayed the score distribution of the first grade in water quality for $85{\sim}100$ points to the second grade in water quality for $70{\sim}84$ points. On KOE-WQI that is classified by indexing for 5 categories of pH, DO, $BOD_5$, COD and T-coli and classified into 5 groups from 90 points or above for outstanding and 29 points or below for very bad, and the water quality distribution is made ranged from the first grade in water quality for 90 points or more to the third grade in water quality for $69{\sim}50$ points. In addition, for the contribution of the water quality decline, the Environmental standard has significant dependency on the $BOD_5$ density, with K-WQI contributing in various water quality decline depending on the environment around the river area of $BOD_5,\;T-N,\;NH_3-N,\;NO_3-N,\;T-P$, and E-Coli, and KOE-WQI acting os the factor contributing to lower the water quality decline by $BOD_5$, COD, and T-coli. As such, the current water quality environment standard has high dependency on $BOD_5$ and KOE-WQI excludes some nitrogen and phosphorus that considers the river environment that the grade in water quality is set by some category, and K-WQI reflected well of the ecology environment of rivers with the diversity of the assessment factor as well as to have the low dependency of specific factor to be objective.
