Functional thinking is a central topic in school mathematics and the purpose of teaching functional thinking is to develop student's functional thinking ability. Functional thinking which has to be taught in elementary school must be the thinking in terms of phenomenon which has attributes of 'connection'- assignment and dependence. The qualitative methods for evaluation of development of functional thinking can be based on students' activities which are related to functional thinking. With this purpose, teachers have to provide students with paradigm of the functional situation connected to the other subjects which have attributes of 'connection' and guide them by proper questions. Therefore, the aim of this study is to find teaching method for functional thinking by situation posing connected with other subject. We suggest the following ways for functional situation posing though the process of three steps : preparation, adaption and reflection of functional situation posing. At the first stage of preparation for functional situation, teacher should investigate student's environment, mathematical knowledge and level of functional thinking. With this purpose, teachers analyze various curriculum which can be used for teaching functional thinking, extract functional situation among them and investigate the utilization of functional situation as follows : ${\cdot}$ Using meta-plan, ${\cdot}$ Using mathematical journal, ${\cdot}$ Using problem posing ${\cdot}$ Designing teacher's questions which can activate students' functional thinking. For this, teachers should be experts on functional thinking. At the second stage of adaption, teacher may suggest the following steps : free exploration ${\longrightarrow}$ guided exploration ${\longrightarrow}$ expression of formalization ${\longrightarrow}$ application and feedback. Because we demand new teaching model which can apply the contents of other subjects to the mathematic class. At the third stage of reflection, teacher should prepare analysis framework of functional situation during and after students' products as follows : meta-plan, mathematical journal, problem solving. Also teacher should prepare the analysis framework analyzing student's respondence.

This paper is to classify old county-maps of Dongrae-bu(東萊府), Busan in late-Chosun dynasty and to analyze place names in maps comparatively. 26 maps covering Dongrae-bu were collected from the old county-map atlas(郡縣地圖帖) and Eupji(邑誌). By e comparative analysis of contents, those maps can be classified into four types. The first type(named 'Haedong-Jido(海東地圖)') included 7 county-maps in which information of military, and administrative contents are mainly mapped. The second type(named 'Yeongnam-do(嶺南地圖)') included 5 coon maps in which information about beacon routes and road systems were regarded as very important. The third type(named 'Grid-system map(方眼式地圖)') included 4 county-maps which were drawn as same scale with 20-ri(理) grids. The fourth type(named 'Local Count-map(地方郡懸地圖)') included 7 county maps which were drawn by local mappers. Comparative analysis of place names between those four types revealed that Grid-system maps were developed toward the large scale whole map of Korea in the 19th century.

Land reservation policies are twofold: Land Banking and Reserved National Lands. The former purchases land for public development before prices rise and controls supply and demand. The latter reserves land for future administrative needs. Both systems aim to reserve land for future supply if prices increase. However, these policies lack responses to contemporary environmental changes, such as the carbon-neutral society and development-restricted zones. This study proposes policy reform to preserve environmental value by evaluating land in metropolitan areas using six ecosystem service variables. Target areas are Gapyeong-gun, Pocheon-si, and Yeoncheon-gun in Gyeonggi Province. Short-term improvements include evaluating environmental value, mid-term measures involve adding environmental considerations to reservations, and long-term measures include expanding the Ministry of Economy and Finance's role in integrated management.

All the teaching items in a textbook are normally arranged in a prescribed teaching order. However, one can easily find that the textbooks of the same kind, even with the same teaching items, show different arrangements. Without learning preceding teaching items, students may have a difficulty in understanding the teaching items. In this sense, it is very important to decide how to arrange teaching items in terms of teaching sequence. As a solution to this problem, lsamu Matsubara presents a method based on the graph theory. The four types defined in his method are the straight type, the group type, the branch type, and the independent type. Among these, the three types except the straight type lack the objectivity. An objective solution to these three types, based on the fuzzy theory. is propopsed in this paper.

The aims of our study are to investigate the nature of mathematical reasoning and the teaching of mathematical reasoning in school mathematics. We analysed the process of shaping deduction in ancient Greek based on Netz's study, and discussed on the comparison between his study and Freudenthal's local organization. The result of our analysis shows that mathematical reasoning in elementary school has to be based on children's natural language and their intuitions, and then the mathematical necessity has to be formed. And we discussed on the sequences and implications of teaching of the sum of interior angles of polygon composed the discovery by induction, justification by intuition and logical reasoning, and generalization toward polygons.

The purpose of this study is to suggest a model for increasing international use of Korean scholarly journals. Recently DOI and open access are remarkable from the standpoint of increasing the opportunity of global exposition and citation of domestic scholarly journal papers. The data used in investigation and analysis were from KAMJE, KISTI, DOAJ and SCIMAGO. The model comprising DOI service and open access is obtained through analyzing DOI and open access utilization models and investigation on both.

With increasing of utilization of 1/1,000 Digital-Map being constructed with NGIS project, it is entering upon the stage that problem as the inspection of position accuracy of Digital-Map before its use. This paper evaluated position accuracy of Digital-Map being based on the construction of college facility management system into small area and presented modification/renovation of Digital-Map on area being occurred position error. With a view to evaluation of position error to building using RTK survey, position error was shown more than 0.5mm that is prescribed in survey-law. In order to acquire good position accuracy, first we carried out Static survey to college and selected control point. And, we evaluated coordinate value to important building from control point and compared these results with RTK survey results. Second, we carried out Affine transform based on the control point of building being surveyed with RTK, transformed pre-constructed Digital-Map and compared these results with RTK Survey results. We analyzed first and second method and presented improvement method of position accuracy of Digital-Map suited on small area.

This study presents plans to prevent environmental noise by using noise maps when establishing development projects and targets strategic environment assessments for urban master plans and environmental impact assessment for urban development projects. Strategic environment assessments for urban master plans include the examination of plan validity and location appropriateness in consideration of the effect of environmental noise by comparing development plans with noise maps, and the establishment of long-term measures through comprehensive assessment of present noise conditions and noise effects from development plans. Environmental impact assessments for urban development projects propose enforcement plans, including analysis of present noise conditions around development areas, overall evaluation of present noise conditions and the noise effect from development projects, and selection of optimal measures by comparing noise maps with various alternatives.
