It is impossible to call in the cost of map-production from the supply cost because the map produced in NGI is the public property. The aims of this research are to calculate a map manufacture cost and to assess the reasonable map prices with considering public property of map. For these aims, We have calculated the cost according to the scale and the form of paper and digital map, have determined the map supply cost, and have analyzed the situation of map supply and the map circulation market. We propose two alternatives. Firstly, supply price of map is reached the goal price after 6-years(raising ratio 30%) and Secondly, supply price of map is reached the goal price after 3-years(raising ratio 50%) because map supply price raising ratio is very much if research results are reflected after 1-year.

This study focused on the relationships among teachers'playfulness, teachers'positive play beliefs, teaching efficacy on play and teacher's strategies of problem behavior guidance, and especially the mediating effects of teaching efficacy on children's play. Subjects were 151 early childhood teachers in Seoul and Chungcheungnam-do. The collected data were analyzed using simple regression, hierarchical multiple regression and the Sobel test. The main results of this study were as follows. First, teachers' playfulness and teachers'positive play beliefs had a positive influence on their proactive, positive reactive strategies of problem behaviors. On the other hand, teachers' positive play beliefs had a negative influence on their negative reactive strategies of problem behaviors. Second, teachers' playfulness and teachers'positive play beliefs had a positive influence on their teaching efficacy on play. Finally, the effects of teachers' playfulness on their proactive, positive reactive strategies of problem behaviors of preschoolers were totally mediated by their teaching efficacy on play.

The purpose of this study was to investigate the teaching activities of guidance teachers in student teachers' planning mathematics lesson and the role of guidance teachers in teaching practicum. To fulfill the purpose, 54 student teachers participated in teaching practicum in G university of education located in G city were selected as subjects and gathered data by asking student teachers to record the interaction process with guidance teachers in detail. By analyzing the teaching activities, the conclusions were drawn as follows: First, guidance teachers' teaching activities in student teachers' planning a lesson were focused on the strategies of teaching and organizing activities according to the ability level of students in the classroom. Second, four types of guidance teachers were identified by analyzing teaching activities as noninterference, supervision, guidance, cooperation. Most of guidance teachers can be indexed as guidance. Third, more effective teaching practicum, guidance teachers need to understand the role of guidance teacher in teaching practicum and systemic program for teaching practicum should be developed.

This paper focused on three drawbacks exposed in subject matter related to solid figures in elementary school math textbook. First, general solid figure are introduced before rectangular parallelepiped and cube in fifth grade math textbook, and prism and pyramid in sixth grade math textbook are introduced. Second, the process of abstraction from concrete objects to solid figures is insufficient in sixth grade math textbook. Third, some definitions in subject matter related to solid figures are inconsistent and ambiguous. The following four suggestions can be put forward as a conclusion based on these results. First, subject matter in textbooks must be correspond with that in curriculum. Second, it is necessary to inform teachers of range of subject matter through teachers guide book and manual for curriculum definitely. Third, each grade subject matter in math textbooks must be reexamined. Fourth, regular modification of math textbooks must be possible institutionally.

In recent years, there are many awareness and demand for digital convergence of the future. In information technology, especially, convergence with other studies such as regional studies, literature and humanities should be needed because information technology is closely related to real life. Culture atlas represents various aspects related to culture visually using points, arcs, and more in the map. Thus, it should be an available tool to survey cultures efficiently in digital environments. For oversea region study, especially Mediterranean region research, we suggest the way to apply electronic culture atlas in this paper. In detail, design and implementation a study on Electronic Culture Atlas for overseas area. Research results for oversea regional studies can be expressed visually by utilizing digital culture map implemented in this paper. Therefore, digital culture atlas should be used as convergence media between information technology and other studies such as regional studies, humanities and so on, tools for oversea regional studies, and exhibition of research results.

초등 수학 교과의 내용을 아동들에게 정확하게 가르치기 위한 목적으로 교사에게 제공되는 교수-학습 자료 지침서로서 교사용 지도서의 역할은 대단히 중요하다. 그러나, 수학을 전문적으로 전공하지 않은 초등교사의 입장에서는 각 차시별로 전개되는 내용들 사이의 연관성이나 위계성에 대한 보다 더 상세한 지도내용에 대한 안내가 필요할 것으로 사료된다. 따라서, 본 연구에서는 초등수학 3-나 단계를 중심으로 각 차시별로 전개되는 내용들 사이의 연관성에 대한 보다 더 상세한 지도내용 뿐만 아니라, 수학사 및 실생활 관련자료, 동기유발 자료 등을 이용하여 수학사 및 교사용 지도서를 수정, 보완하여 재구성한 후, 일선 학급에 투입한 후, 교사들과 아동들의 반응들을 분석하여, 향후 보다 더 개선된 교사용 지도서를 만들 수 있는 아이디어를 제시 하고자 한다.

For the effective use of spatial data, it is necessary to translate the diverse digital map data (here, digital map for car navigation system) into common GIS data structure(here, ARC/INFO). For this purpose, analysis on the structure of the established digital map was fulfilled, the data model for effective translation tool was designed. As a result, the possibility to translate diverse digital map structures (database) into GIS tools and to share them, with the users' point of view, was successfully verified.

This study was performed to find out how to improve the usefulness and effectiveness of the field practice program in Library and Information Science by diagnosing the practical instructor's perception of the overall field practice in the Library and Information Science. To achieve this goal, we conducted a research on the current situation and a measurement in perception of the field practice program through a survey of practical instructors at practical training institutions. We, then, analyzed the factors affecting the perception and examined the relationship between the effects. As a result of investigating the factors affecting the perception of field practice, 'operational accountability for the field practice program' was found to be a significant factor among other factors such as the general characteristics of the practical instructors, the characteristics of library related work and the field practice status of the practical training institutions. And factors of 'practice environment' and 'practice instruction method' have been identified to have a significant impact as a result of analyzing how the six factors constituting the perception of field practice effect on the overall perception of field practice of the practical instructors.
