錦江 水質管理를 위한 대청댐 放流量 決定 = Determination of Daechung dam outflows for water quality management in Keum River

다국어 초록 (Multilingual Abstract)

In korea, the rivers is usually lack of water discharge except the summer. That reason is a characteristic precipitation pattern. The precipitation pattern is downpour in the summer time and water discharge drain out a short span of time. Therefore, a water management is hard to control. Occasionally, in drought term, the aim of water quality is far off.
In this study, after the Deachang Dam lower Keum River watershed was selected by the target watershed, an on the-spot survey was carried out. the data from getting an on the-spot survey was used to verify the model that is CE-QUAL-RIV1. The model is a first oder dimensional river model and is made up a Hydraulic Analysis module and a Water-quality Analysis module. First dimension Non-linear Continue Equation of St. Venant and 1st dimension Non-linear motion Equation of St. Venant was interpreted 4-point implicit finite difference method in the Hydraulic module.
The Water-quality module was applied Holly-Pressman's 2 point - 4 order explicit method. When drought term, the model was applied the data to verify ability of Hydraulic Analysis and Water-quality Analysis. Also, the parameters sensitivity was analyzed. The parameters were corrected by an on the-spot data that was get at September, 2002. After than, model was verified using the date when getting October, 2002. By using verified model, the pollutants were pursued when pollutants release at an upper stream, and improvement in Water-quality was evaluated as control of discharging an upper stream dam.

This thesis intends to research the effect of literary activities using wordless picture books on children's creativity. Four main research questions of the present study are as follows: First, do literary activities using wordless picture books improve children's creativity? Second, do literary activities using wordless picture books improve children's creativity in language area? Third, do literary activities using wordless picture books improve children's creativity in geometry? Fourth, do literary activities using wordless picture books improve children's creativity in kinesthetic expression?
The subjects of this study were 34 five-year-old children boy: 16 ; girl: 18 from a kindergarten located in Daejeon Metropolitan City. Two wordless picture books such as "Bang" of an Apple" and "The Apple and the Butterfly" were used. The experimental group participated in literary activities whereas the comparison group did not.
To research the effect of literary activities using wordless picture books on children's creativity, the experimental group participated in literary activities using wordless picture books, twice a week (40 minutes per 1 session), for 8 weeks during two months. The total amount of time of the literacy activities was 640minutes for 16 sessions. The comparison group participated in general kindergarten curriculum and studied language activity materials related with themes of life in language area.
The strategy used by the experimental group was " Interactive Discussion" (Lim Youngsim 1994; Morrow 1998). With reference to teaching methods of wordless picture books (Lee Gyeongwu 1998), literary activities (such as) "thinking", "predicting", "discussing", "creating their own stories", and "presenting" were performed.
To measure children's creativity, Integrative Creativity Test for Children by Jeon Gyeongwon (2004) was used. Several ANCOVAS (Analysis of Covariance) of the pretest and the post-test of the experimental and comparison groups were computed.
The results of the study were as follows: First, literary activities using wordless picture books were effective in improving children's creativity in general. Second, literary activities using wordless picture books were effective in improving children's creativity in language area. Third, literary activities using wordless picture books were effective in improving children's creativity in geometry. Fourth, literary activities using wordless picture books were effective in improving children's creativity in kinesthetic expression.
