The purpose of this study is to suggest the methodology to develop variable-scale network model, which is able to induce large-scale road network in detailed level corresponding to small-scale linear objects with various abstraction in higher level. For this purpose, the definition of terms, the benefits and the specific procedures related with a variable-scale model were examined. Second, representation level and the components of layer to design the variable-scale map were presented. In addition, rule-based data generating method and indexing structure for higher LoD were defined. Finally, the implementation and verification of the model were performed to road network in study area (Jeju -do) so that the proposed algorithm can be practical. That is, generated variable scale road network were saved and managed in spatial database (Oracle Spatial) and performance analysis were carried out for the effectiveness and feasibility of the model.

Characteristics of chemistry education during the enlightenment period in Korea are examined by analyzing chemistry textbooks used in the period. Specifically, the analysis is made from the aspects of science, students and teachers. As a result it is found that; first, scientific knowledge itself is emphasized, contrary to those described in the curriculum of chemistry used in the period, and it consists of introduction, non-metals, metals and organic chemistry in chemistry textbook, second, the level of chemistry is similar with that in present high schools, and its technical constitution might have been difficult for a student to study with an experiment, third, terminology lacks consistency and some textbooks include contents of other subject. It is therefore believed that the chemistry textbooks of the enlightenment period is scientifically incomplete and would not have been easy for the teachers to use them to teach the students. In addition, considering the students as a beginner of modern sciences, study level could have been too difficult for them to follow. In conclusion, it appears that chemistry education during the enlightenment period in Korea was not so successful.

The purpose of this study was to analyze the geological terms used in the elementary school science curriculums from 1876 to present. We collected the data of geological terminologies based on what is being used in the revised 2007 national curriculum. In this study, data was divided into three periods according to political events, "The Modern Enlightenment Period (1876~1910)", "The Japanese Colonial Period (1910~1945)", and "The Current Curriculum Period (1945~present)". During the early modern enlightenment period, translated Chinese characters' terminologies by western scholars in Qing-China were used in science books. The late modern enlightenment period, we used many translated Japanese textbooks in schools, which naturally introduced the way that Japan's terminology is used. In the Japanese colonial period, Korean students had to study science subjects written in Japanese characters, so they had used Japanese terminologies of science. After the liberation of Korea from the Imperial Japan, there was an efforts to make new Korean terminologies of geology under the new current national curriculum. However, the terminologies used in Korean textbooks ended up using and borrowing the same way that the Japanese-Sino terms of science used later.

최근 서울시는 청계천의 유지용수 및 환경개선을 위해 한강물을 이용하였다. 이를 계기로 앞으로 유사한 용도로 물을 사용하려는 지방자치단체의 수요는 크게 증가할 것으로 예상된다. 이렇듯 환경을 개선하기 위한 용수의 수요는 이미 현실적인 문제로 대두되고 있음에도 이에 대한 기술적 분석이나 관련 제도가 잘 정비되지 않은 실정이며, 심지어 그 개념 및 용어의 정의조차 모호한 상황이다. '환경개선용수'는 간단하게는 '하천의 수질환경을 개선하고 하천의 기초 생태계를 보호하는 물'을 의미할 수 있다. 그러나 광의로는 효율적인 하천관리와 환경보전에 대한 국민들의 관심이 증가하면서 친수 공간 확대 등의 생활상의 필요까지도 포괄하는 개념이다. 환경개선용수로 인한 편익이란 수량 확보로 인한 수질 정화, 하천생태계 보전, 하천경관 개선, 유지유량 확보, 사회 생활환경 형성 등의 이득을 말한다. 본 연구의 목적은 일반적인 환경재의 가치평가기법을 조사하여 장단점을 분석하고, 이를 바탕으로 환경개선용수에 의한 하천경관개선편익의 계량화 방향을 제시하는 것이다. 특히 수자원의 환경편익 계량화와 관련한 국내 외 연구를 폭넓게 참고하고자 한다. 전통적인 경제학의 영역에서 환경재는 일반적으로 사치재로 분류할 수 있다. 따라서 국민소득수준의 향상에 따라 환경에 대한 사회적 욕구도 증가할 것이며, 이는 곧 환경개선에 의한 편익이 계속 증대될 것임을 의미한다. 수자원사업의 환경개선용수로 인한 편익의 계량화는 타당성분석의 신뢰성 향상으로 사업의 사회적 수용성을 높이는데 도움이 될 것으로 판단된다.

The goal of this study is to develop a skill system for the areas of textile and clothing among the skill systems that require basic examination in the development of skill standards. More specifically, the study aims to classify skills in the areas of textile and clothing and to develop respective skill level. We classified skills and created the skill level through a study of documents, interview with experts and in-depth discussions with expert group centering on terminologies commonly used in the industrial settings. As a result of skill classification, we were able to classify skills into three categories in medium-scale classification, 10 categories in small-scale classification, and again into total 22 categories. We classified the skill level in the areas of textile and clothing into 7 stages. Based on the skill system, we provided definition of skill and skill group, definition of each different skill, and performance standard by skill and level.

The purpose of this study is to verify the research trends on 101 articles about mathematical creativity published in domestic journals. The analysis criteria are as follows: (1)What kind of terms the articles use to refer to the creativity in mathematics education, (2)Whether the researchers conceptualize such the terms or not, (3)Whether the definitions are domain-specific or not, (4)What perspectives, categories and levels of the articles have on creativity. The results of this study show the following. First, numerous articles used 'mathematical creativity' in order to point to the creativity in mathematics education. Second, among the 101 selected articles, 60 (59.4%) provided an explicit definition of the mathematical creativity and 19(18.8%) provided an implicit definition. Among the 79 articles, only 43(54.4%) provided domain-specific definitions. Second, the percentage of articles preferring one perspective over the other 3 perspectives were similar. Third, the rate of articles which focused on press(environment) of all categories (person, process, product, press) was low. Fourth, regarding the levels of creativity, most articles were done on little-c creativity level, on the other hand, the articles having an interest in mini-creativity were very rare. Based on these results, necessities of explicit and domestic-specific definition, whole approach of mathematical creativity, and articles focusing on the mini-creativity level should be reported.

This study aimed to measure the health literacy among Korean elderly living in the community, and to explore the factors influencing health literacy of the elderly. A descriptive correlational research design was used. The sample consisted of 411 elders who were conveniently selected from the community welfare center users in Seoul and Gyeong-gi province. Data were collected from face-to-face interviews by trained interviewers between January, 7 and February, 4, in 2008. Health literacy was measured by Korean Health Literacy Scale developed by Lee(2008). Descriptive statistics, ANOVA, t-test, and multiple regression were used to analyse the data. In result, the mean score of health literacy was 17.46(${\pm}5.73$) with a range of 0 to 25, 42.8% of elderly had limited health literacy problems. Multiple regression showed that 26.5% of variance in health literacy was accounted for by the combination of education, age, living arrangement, and income. In conclusion, various strategies to improve health literacy in elderly population in the areas of health education and disease management should be needed to reduce health disparities among elderly.

The purposes of this study were to analyze vocabularies used the section of 'Living Earth' in 11-grade Earth science textbooks with the Science Word Analysis (SWA) program and to investigate the vocabularies selected by the 11th grade students as difficult ones. For the purpose, we extracted the Earth science vocabularies from six textbooks, and classified into the scientific and non-scientific vocabularies with SWA program based on the standard Korean language dictionary. Also, we investigated the difficulty of each vocabulary by using questionnaire to three hundred sixty students. From the results analyzed with the program, it was found that the frequency of the scientific vocabularies out of the level was the largest any other level in all textbooks. And from the survey, most of the vocabularies selected by students as difficult to understand were classified into out of the level. From these results, it were suggested that the students' cognitive level should be considered in developing science textbooks and difficult vocabularies should be replaced to easy ones within the limits of changeless in the meanings.
