This study is to develop a Priority Decision System for Redevelopment (PDSR) which is able to decide the priority for redevelopment of agricultural reservoirs. The major scopes of this research are to make the related GIS data like hydrologic unit map and other thematic maps to determine the suggested priority index (PI), and to develop the PDSR handling the GIS data and calculating weighing factors for the PI. In order to make the weighing factor decision module, the AHP technique was adopted. The result of the weighing factor calculation was showed PC (Possibility Criteria) and RC (Restriction Criteria) were 76% and 24% respectively. Which means that most of the specialist selected PC category prior to RC because of whom to mostly of major technique. So, in order to make more objective result, the selection of specialists is important like environmental activists or local residents and so on. The product from this research can provide more scientific support to decide the priority decision.

Multivariate statistical analysis was applied to 110 dam heightening reservoir to classify the building conditions for waterfront centered around cultivated area using data of land cover, landscape, additional water quantity, local economic, tourism resources, and accessibility related variables. Five factors were extracted through factor analysis based on eigen value criteria of more than one. These five factors together account for 68.2% of the total variance. Characteristics of five factors for the downstream of dam heightening reservoirs are building conditions of waterfront, economic conditions, additional water quantity, eco-tours, and accessibility of tourism resources respectively. Five clusters were classified through cluster analysis based on factor score. The classified result shows that third cluster has remunerative terms for building waterfront.

논 농업용수의 외부효과 구분과 비용산정에 따른 경제성 분석
김해도,허승오,조진훈,나민철,Kim, Hae-Do,Hur, Seung-Oh,Jo, Jin-Hun,Na, Min-Chul 한국관개배수위원회 2010 한국관개배수논문집 Vol.17 No.2
The subject of externality of agricultural water supply has been discussed in the OECD AC ( Organization for Economic Cooperation and Development Agriculture Committee) while argued between monsoon Asian developing countries and the agricultural product export nations (Australia, EU, etc). It argued that a 'positive' approach to multifunctionality views agriculture as an economic activity with multiple, interconnected outputs or effects, and a 'normative' approach interprets multifunctionality in terms of the multiple roles assigned to agriculture. and the agricultural product export nations insisted 'negative' approach to externality of agricultural water supply like causing water pollution. So, in this study, define the externalities (positive, negative and economic, environmental) in terms of the agricultural water supply and calculate benefit and cost each the externalities by cost estimation. As results, BC is calculated to 1.28 which means that it is more economical to agricultural water supply and shows that although the negative exernalities comes out while supply the agricultural water, it still more valuable to supply the agricultural water.

The aim of this study was to analyze the operation plan for heightened agricultural reservoir, in terms of water supply to downstream paddy fields and instreams. Operation of agricultural reservoir before the heightened reservoir project is easy to manage because of its single purpose, which is irrigation water supply. However, after proceeding the heightened project, there is needed to be set the operation rule because of its multiple purpose, which is water for irrigation and supply to the stream. In this paper, propose the method of design the criteria of supply to the stream and operation rule curve for the heightened reservoir. According to simulation results by proposed operating rule for the Gumsa reservoir, the yearly amount of water supply to the stream can be 2,588 thousand $m^3$, 3 times of the heightened space (2,588 thousand $m^3$).

부산 · 경남지역 중학교 남학생의 컴퓨터 음란물 접촉 실태 및 관련요인
김해옥,손해숙,박수경,엄상화,전진호 인제대학교 1999 仁濟醫學 Vol.20 No.1
부산ㆍ경남 김해시 일부 남자 중학생들에 있어서 컴퓨터 음란물 접촉 수준과 관련요인을 관찰하기 위하여 1997련 12월15일부터 12월24일까지 부산시내 3개 남자중학교, 김해시내 2개 남자 중학교 학생 519명을 대상으로 설문 조사를 실시한 결과 컴퓨터 음란물 접촉은 학년이 높을수록, 컴퓨터 사용시간이 길수록 많았으며, 통계적으로 유의하지는 않았으나 형이 있으며, 개인이 컴퓨터를 가지고 있는 경우 많았다. 컴퓨터 음란물 접촉자들이 음란물에 대하여 비접촉자에 비하여 긍정적으로 생각하는 경향이 있었으며, 이성 친구와 신체적 접촉 수준도 적극적이었으며, 원하지 않는 임신의 처리에 대하여서도 접촉 군에서 '인공유산'에 대한 긍정적인 태도를 보여 전체적인 성 관련 태도와 행동이 개방적이며 적극적이었다. 이상에서 컴퓨터 음란물 접촉이 학년이 높을수록, 컴퓨터 사용 시간이 길수록 많은 것으로 관찰되어, 학생들을 컴퓨터 음란물 접촉으로부터 보호하기 위하여 학년에 따라, 즉, 적절한 시기에 적합한 내용의 성교육이 실시되고, 학년에 따른 올바른 컴퓨터 사용에 대한 교육이 실시되어야 할 것으로 생각된다. 컴퓨터 음란물 접촉자에서 성과 관련한 태도와 행동이 비접촉군에 비하여 적극적이고 개방적이나, 본 연구는 단면연구로서 관찰된 성과 관련한 태도와 행동의 차이와 컴퓨터 음란물 접촉과 인과성은 관찰되지 못하였다. 본 연구에서 관찰된 변수를 중심으로 추후 선.후 관계에 관한 연구가 수행되고 빠른 컴퓨터 보급과 컴퓨터 통신 사용의 증가를 고려할 때 실태에 관한 연구도 지속적으로 이루어져야 할 것으로 생각된다. Objective: This study observes the status of the contact to lascivious computer programs, the difference of sexual attitude, and the behaviour between the students who contacted to lascivious computer programs and the students who did not. Methods and Materials: The questionnaire survey was done on 519 boy students from five middle schools in Pusan and Kimhae area from December 15 to December 24, 1997. The data were analyzed by PC SAS program ; X2-test. multiple logistic regression. The level of significance was 0.05. Results: The grades were increasing and the hours of computers use were longer, the percentages of the students who contacted to lascivious computer programs were higher, significantly. In attitude about lascivious material including lascivious computer programs, 19.0% of the students contact to lascivious computer programs had the experience of petting and sexual intercourse. 69.4% answered that the artificial abortion was needed for unwanted pregnancy. There was the difference in sexual attitudes and behaviour between the students who contacted to lascivious computer programs and the students who did not. Conclusion: It suggests that the sex and computer education with proper program in proper age is necessary. The further causative study between the exposure of lascivious computer programs and sexual attitudes and behaviour is needed.
