A project constructing sewerage facilities in 9 upstream areas of 7 multi-purpose dams will have been completed by 2011. After all constructing and retrofitting of the new and the existing sewerage facilities, integrated management system with operation and control functions for the each levels of facilities will also be utilized. In this study, we studied how to compose the organization taking responsibility of the integrated management system and analysed human resources saving effect against conventional method of individual management of each sewerage facility. As a result, a method estimating the human resources in employing the integrated management among several sewerage facilities at upstream areas of dams were presented and some 23% of human resources could be saved by integrated management. Commissioning to a specialized public institute showed the highest B/C ratio of 4.5 among commissioning to local public corporations, commissioning to private corporations, and role-sharing partnership, etc.

It requires an interim performance assessment for BTL business of the sewerage rehabilitation which continues from 2005 till now. Means, It is necessary to make an interim performance assessment and an analysis of an business effect of the sewerage rehabilitation BTL projects which still continues, and we presented an improvement method of the new sewerage rehabilitation project in future. This paper has conducted an analysis of the business effect for 3 local government BTL projects which are completed and under operation as of now in Jincheon-Gun, Cheongju-Si and Gangjin-Gun. As a method of business effect analysis, we conducted a business effect of the 3 places using the index set which we previously set for the business effect analysis. The index set in this research was sectionalized to an improvement effect of operating wastewater treatment plant, an benefit effect of the direct cost, an benefit effect of the indirect cost and an environment friendly effect. We, in this paper, conducted an business effect analysis for 3 sewerage rehabilitation BTL projects which are completed or under operation recently as a demonstration, however we judge that an business effect analysis shall be conducted in a stage that a significant time for operation has passed since the completion of the construction in order to induce an actual business effect of the sewerage rehabilitation BTL project.

본 연구에서는 서술형 검사를 이용하여 고등학생의 문제 해결 전략 수행 능력을 측정하고, 논리적 사고력과 전략 수행 능력 사이의 관계를 조사하였다. 서울시에 소재한 두 고등학교에서 4학급(N=187)을 선정한 후, 전략 수행 능력 검사와 논리적 사고력 검사를 실시하였다. 전략 수행 능력의 채점틀은 7개 하위 범주-문제의 조건 파악, 관련 법칙 회상, 하위 목표 설정, 물리량 유도, 수리적 수행, 논리적 전개, 검토-로 구성하였다. 채점에 대한 신뢰도는 분석자간 일치도 .92로 확인하였다. 연구 결과, 학생들의 조건 파악 능력과 수리적 수행 능력은 비교적 높으나, 하위 목표 설정 능력과 검토 능력은 저조한 것으로 조사되었다. 전략 수행 능력 검사의 전체 점수 및 하위 범주별 점수는 논리적 사고력과 유의미한 상관을 나타내었다. In this study, high school students' problem-solving strategy-performing ability was measured by an essay-type test. The relationship between students' logical thinking ability and strategy-performing ability was also investigated. Four classes (N=187) were selected from two high schools in Seoul, and the strategy performance ability test and the Group Assessment of Logical Thinking (GALT) were administered. Evaluation scheme for strategy-performing ability consists of 7 subcategories - understanding given of problems, recalling related law, setting up subgoals, deriving physical quantities, logical progress, mathematical execution, and reviewing. The intercoder agreement for scaling was .92, which indicated substantial strength of agreement. The results revealed that students' ability of understanding given of problems and mathematical execution was relatively high. However, their ability of setting up subgoals and reviewing was very low. The total scores of the strategy performance ability test and all of the scores of each subcategory were significantly correlated with the GALT scores.

댐상류 하수도시설의 통합운영관리방안에 관한 연구(I) - 통합관리전문기술지원단의 운영방안에 대하여 -

Integrated management system (IMS) for sewerage facilities has been installed at 7 dams and 9 watersheds since 2006. However, there has been no decisive plan on how and who to manage efficiently IMS after finishing the construction. Therefore, in this study, it was suggested that a new organization, so to speak, a technical support team for integrated management that may operate and manage IMS efficiently, could need to be set up. Three scenarios were evaluated depending on the type of allocating human resources to new organization considering each levels of sewerage facilities. Economic analyses on each scenarios of human resources allocation were also carried out. As a result, establishing the technical support team for integrated management was estimated to give the net benefit from 1.3 billion to 20.6 billion won for 15 years.

문제 해결 전략에서 시각적 조직화와 협동학습의 효과

김창민,노태희,전경문,여경희,안충희 한국과학교육학회 2000 한국과학교육학회지 Vol.20 No.4

본 연구에서는 문제 해결 전략에서 시각적 조직화와 협동학습의 효과를 조사하였다. 고등학교에서 세 학급(N=127)을 선정하여 시각적 조직화를 이용한 문제 해결 전략을 개별적으로 사용하는 집단(SV), 협동학습 환경에서 사용하는 집단(SVC), 그리고 통제 집단으로 배치하였다. 수업 처치 후 객관식 문제 해결력, 전략 수행 능력, 화학 학습에 대한 불안, 수업 참여도, 학습 동기를 조사하였다. 연구 결과 객관식 문제 해결력에서는 집단간 차이가 유의미하지 않았으나, 전략 수행 능력에서는 수업 처치의 주효과가 나타났다. SV 집단과 SVC 집단의 점수가 통제 집단보다 높았으며, 특히 하위 영역 중 문제 이해와 관련 법칙 회상에서 높은 점수를 보였다. 수업 참여도와 학습 동기 검사에서도 SV 집단과 SVC 집단의 점수가 통제 집단보다 유의미하게 높았다. 그러나 시각적 조직화를 이용한 문제 해결 전략이 학생들의 화학 학습에 대한 불안을 유의미하게 감소시키지는 못했다. In this study, the effects of visual organization and cooperative learning in problem-solving strategy were investigated. Three classes (N=127) at a high school were assigned to SV (Strategy-Visual organization) group, SVC (Strategy-Visual organization-Cooperative learning) group, and control group. After instructions, students' multiple-choice problem-solving ability, strategy performing ability, anxiety about chemistry learning, perception of involvement, and motivation to learning science were examined. Although multiple-choice problem-solving ability was not different significantly, there was a significant main effect in strategy performing ability. The scores of the SV and SVC groups were significantly higher than those of the control group, especially in the subcategories of problem understanding and recalling related principles. In the tests of perception of involvement and motivation to learning science, the scores of the SV and SVC groups were also significantly higher than those of the control group. However, problem-solving strategy using visual organization could not alleviate anxiety about chemistry learning.
