The purpose of this study was to examine school-level science elective-centered curriculum operation and teachers' perception of their instruction of elective-centered science courses. Data were collected from 12 science teachers in 12 high schools in the metropolitan Seoul area through semi-constructed interviews. The results showed that students were supposed to select science subjects under insufficient guidance and their choices on subject were also restricted due to school administrative processes such as teacher's instructional time allocation. Participants were well-perceived different group characteristics among humanities course and science course students toward science learning, still, they felt difficulties in valuing students' variety by differentiating contents and teaching methodologies due to school assessment system and workload of extra instructional material preparation. Influenced by the current college entrance examination system, low motivation for humanities course students and students' choice concentrated in chemistry and life science for science course students, were pointed out as main problems. As a way to improve science education for 11th - 12th graders, developing customized science curriculum for humanities course and science course respectively, changing of entrance system into increasing importance of science for students who will major in non-science fields, and designations of essential prerequisite science subject for students who will major in engineering & science fields, were suggested.

The purpose of this study was to present improvement directions of college scholastic ability test on industry department. Industry department test were classify and abstracted sampling test on contents and movement domain, analyzed example items of college scholastic ability test on industry department. Research methods used in this study were review of related literature, the item analysis and item pattern analysis between college scholastic ability test on introduction to industry and curriculum, contents of textbook. After finding a problem of developing items, trying to find a solution to the problem and developing an up-to-date method of items was to present improvement. Based on the result of the study, some recommendations for future researches were made as follows: First, a phenomenon of making same contents items over again and no making items not on made the items ever have to cut. Second, Time to read and make sense of items have to reduce because depend on the degree of difficulty related on time to understand of items. Third, the depth of textbook contents has to develop on curriculum this year. Fourth, the succeeding study on linkage between college scholastic ability test and simulation of college scholastic ability test. Fifth, verification validity on contents of new movement domain is developed new and striking test items.

This study aimed to analyze the characteristic of undergraduate students' perception and preference for mathematics. For this purpose, I surveyed 124 undergraduate students' metaphorical expressions about mathematics. I classified the expressions as four categories: a positive form, a negative form, a mixed form, an undecidable form. I investigated the proportion and characteristic of the metaphorical expressions according to the above four categories. Also, I surveyed the students' preference and nonpreference moments for mathematics and categorized them into 6-cases: elementary school, middle school, high school, university, always, and none. In addition, I examined the students' preference and nonpreference reasons for mathematics and classified them according to the 5-factors: grade factor, affective factor, content factor, teacher factor, and other factors. The results of this study as follows: First, the 27% of university students expressed their metaphorical expressions for mathematics as a positive form, 42% as a negative form, and 27% as a mixed form. Also, the preference rate for mathematics was higher as their school years increase and the main reasons of preference were grade and affective factors. The result of nonpreference rate was also higher as their school year increased. Students said that the contents and grade factor were the main factors among the 5-factors.

This paper is to compare the contexts and old place names in old county maps of Goryeong-hyeon(高靈縣) according to the four types of maps. 23 maps covering Goryeong-hyeon were collected from the old county-map atlas(郡縣地圖帖) and Eupji(邑誌). The first type(named 'picture county map') included 8 county-maps in which information of military, and administrative contents are mainly mapped. The second type(named '1-ri grid system map') included 4 county maps in which information about beacon routes and road systems were regarded as very important. The third type(named '20-ri grid-system map(方眼地圖)' included 4 county-maps which were drawn as same scale with 20-ri(里) grids. The fourth type(named 'local county-map(地方郡縣地圖)' included 5 county maps which were drawn by local mappers. Types of toponyms which were included in maps are different by the propose of map-drawing. In the picture county maps, place names from military, and administrative contents are written. In the 1-ri grid system county maps, place names especially from military and transportation are fluent. In the 20-ri grid system county maps, generic name from natural environment, such as mountains are very fluent. In the local county maps, city-walls and castles are drawn exaggeratively and detailed generic name from warehouses and villages are written in those maps. This study shows that Daedongyeo-jido was drawn on the basis of 20-ri grid system county maps with the supplementation of geographical information.

지나친 학과 세분화의 부작용을 줄이고 대학 운영의 효율성을 높이기 위한 대안으로, 유사학과들을 통합할 때 학과를 존치하는 경우에는 학과군으로 하거나, 계열별 또는 학부 체제를 도입할 수 있다. 과거 한 때 잠시 계열화로 대학 입학생을 모집할 당시의 폐단으로 부상된 점을 보완하고, 장기적 안목을 갖게 된다면 실효를 기대할 수 있다. 첫째, 행정의 중복과 복잡성을 배제하여 간소화할 수 있다. 둘째, 교수의 강의 부담이 감소되고 강사 풀제도의 활용이 가능하다. 셋째, 대학의 연구 역량을 강화하여 협동연구, 공동연구, 학제간 연구 활성화를 꾀할 수 있다. 넷째, 전공선택 과목을 다양하게 제공할 수 있고, 전공선택이 쉬워진다. 다섯째, 실험실 공동이용이 가능하다. 이 과정에서 야기될 수 있는 역기능의 문제들은 장기적 안목으로 통합적 교육과정의 시각에서 검토되어야 할 것이다.

일반적으로 설계홍수량은 강우빈도 해석으로 설계강우량을 결정하고 이를 유역유출모형에 적용하여 계산된 유출량을 정상류모의를 통하여 산정하게 된다. 이러한 기존의 설계홍수량 산정방법은 설계강우량 산정에 있어 임의성을 포함하게 된다. 따라서 본 연구에서는 대상 하천 구간의 실측 수위자료를 사용하여 홍수량을 산정하는 방법을 제시하고자 한다. 분석대상 자료로서 남한강 여주지점의 실측 시유량을 선정하였으며 충주댐 완공 이후인 1988년부터 2007년까지의 기간을 대상으로 하였다. 빈도해석을 위한 분석 자료군을 연최대치 계열과 POT(Peaks Over Threshold) 계열의 두 가지 그룹으로 추출하여 홍수량을 추정하였다. 연최대치 계열 분석 결과 Weibull 분포를 적절한 분포형으로 선정하였으며 부분시계열 POT 빈도해석을 수집자료 전체와 기간을 전, 후 10년씩 나눈 세 그룹으로 나누어 수행하였다. 빈도별 확률홍수량 추정 결과 연최대치 계열을 사용한 결과가 부분시계열 POT 방법을 사용한 결과보다 크게 산정되었으며 자료 전체 기간에 대한 POT 빈도해석 결과보다 최근 10년간의 자료를 사용한 결과가 더 크게 나타나 홍수량의 증가 경향을 확인 할 수 있었다.

The purpose of the study is to develop a questionnaire that examines unskeptical attitudes in scientific inquiry context. The questionnaire items were developed through literature research, expert review, and statistical analyses for validity and the differences in scores were identified by gender and tracks. A total of 363 high school students participated in the study. To explore the validity evidence of items, the Rasch analysis and the reliability of internal consistency were performed, and the two-way ANOVA was performed to compare the scores of the unskeptical attitudes between gender and academic track. Self-reporting and Likert-scaling 23 items were developed to measure unskeptical attitudes in scientific inquiry context. The items were developed in the sub-domain of scientific inquiry: 'questioning and hypothesis generating,' 'experiment designing,' and 'explaining and interpreting.' Second, the validity and reliability of the unskeptical were identified in a rigorous method. The validity of items were identified by multi-dimensional partial score model analysis through the Rasch model, and all 23 items were found to be fit to model. Various reliability evidences were also found to be appropriate. It was found that there were no significant differences of unskeptical attitude score between the gender and academic track except one comparison. The developed questionnaire could be used to check an unskeptical attitude in the course of scientific inquiry and to compare the effects of scientific inquiry classes.
