This study looked at worked on remaining landscapes in terms of landscape ecology. It presented some ways to conserve and to activate remaining landscapes with examples of agricultural lands in Hwa-won Gun, Ok-po Myun. The results are as follows: We investigated 20 remaining landscape types and 90 remaining landscapes, and classified them in terms of forest and water zones. To evaluate the investigated remaining landscapes, we produced a grading system using 8 criteria such as vitality, stability, field suitability, type of inner scenery formation, connection, recreation, and culture/tradition. Our evaluation of the vitality found that Grade I had the mast remaining landscapes; Grade II had 28, Grade III had 16, Grade V had four, and Grade IV had none. We evaluated the outer landscape influence using 3 criteria such as divisibility, vitality, and indication. We found from evaluating the type of inner scenery formation that most of the landscapes superior to Grade III were adjacent to water zones and that linear landscapes evaluated as Grade I, and II played an important role in this connection. We evaluated the recreation probability using marks, frequencies, and emergencies of peculiar types. Based on the results, we proposed some ways to conserve and to activate the remaining landscapes classified by grades using the results of the last evaluation. Additionally, we proposed some ways to activate the restoration of the linear axis of the green space function the formation of a buffer green space around matric space, the improvement of the axis of the green space center, and the formation of additional green tracts of land to play the role of stepping stones. We proposed the possibility of improving uniformed farm land structures. This study did not consider the weighting values of the evaluation index. Therefore a more objective study will be needed with an expert-survey in the future.

Schwannoma of the stomach is a rare controversial neoplasm which requires extensive studies to clarify its nature as a stromal tumor or leiomyoma. We describe the pathologic, immunohistochemical, and ultrastructural characteristics of schwannoma of the stomach in a 33-year-old woman. The tumor was a well-circumscribed submucosal mass located in the posterior wall of the midbody of the stomach. Microscopically, the cells were made up of fasciculating bundles of spindle cells featured with peripheral lymphoid cell cuffing. The tumor cells revealed a diffuse, strong immunoreactivity to S-100 protein and vimentin, but were negative to desmin and smooth muscle actin. They also had a focal positive reaction to glial fibrillary acidic protein. Ultrastructurally, many tumor cells showed a number of thin, elongated and interdigitating dendritic-cell-like processes, distinctly uniformed basal laminae, frequent cellular attachments, and microfilaments. These findings support the schwannian nature of the tumor.

In order to understand the local council members' attitudes to the health policy, we conducted mail surveys using self-administered questionaire for 2 months(February and March. 1995). The study subjects were 2.312 local council members in Korea, but only about 11% among whom. 257 persons, responded to 2 times mail survey. This response rate revealed that the local council members was not interested in health care fields. The main results were as follows; The respondents thought that the economic and income development was most important among 15 regional policy agendas and the health care was the 5th or 7th important agenda. They. who had more health needs of and poor access to health care, tended to think that the health care was more important. They considered lobbying to and persuading the civil servants as the best method to tackle the local health care policy agenda. The respondents, who had poor access to health care facilities. tended to set the highest priority for the expansion of public and private health care resources. They expected that the election of local governor would activate the public health program more than thought that the program was implemented more actively than other region. The main opinion of respondents was that the central government had to take over planning and financing for the public health program, and the basic local government had to implment the program and budgeting. The majority of respondents agreed the private dominant medical care delivery system and nation-wide uniformed financing mechanism. Over 60% of them suggested that they were ready to suffer environmental pollution inducing health hazards for the purpose of regional economic and income development. About 75% of them favour the campaign for antismoking regardless of reducing local government's revenue from sale tax.

Almost business enterprises have recently used electronic commerce to conduct their business. Electronic commerce has come to encompass the Internet as well as EDI on private networks begun in the 1960s. The Internet is already changing the way that many companies conduct their business. Domestic electronic commerce has rapidly enhanced, while Int'l electronic commerce has gone steady. There are four issues for developing of Int'l Electronic Commerce. Firstly, The EDI Standardization is to be uniformed and prevailed over the world in UN/EDIFACT authorized by ISO. Secondly, There are two useful systems on Electronic Document Transmission, so called, Bolero project system and Trade Card System. It is thought that Bolero system will be more useful for large trading enterprises, especially, who need a Letter of Credit and electronic B/L, while T/C system is proper to small trade companies who do not need those. Successful results of Bolero system is very important for Int'l electronic commerce enterprises. Thirdly, to secure electronic signature, Int'l Certification Authority is essential for the users of Int'l electronic commerce. Trusted way of distributing public keys is to use a Int'l Certification Authority. The Int'l Certification Authority will accept user's public key, along with some proof of identity and serve as a depository of digital certificates. Both governments and the International business community must involve archiving keys with trusted third parties. Finally, It is important that all the nations and UNCITRAL continue efforts to make legal bases in Int'l electronic commerce concerned, including electronic signature, certification etc.

This study is taken as the part of the cultural research on the Kaspian coastal region, which has a great significance as the start of human civilization and in the history of cultural exchange. This study is focused on the Achaemenid dynasty of the great Persian Empire that Iranians have established on the Parsa region, south of Iran on 6-4th century B.C. This research limits to the tribute-relief illustrated on the stairs of Apadana Palace in Persepolis during the age of Achaemenid dynasty. The objective of this research is classify and analyze Persians and its neighboring tribes, their dresses and the detailed elements of the dresses to complete the typology of the dresses in that period and use this to categorize the features of nomadic and agricultural tribes of costal areas of the Mediterranean Sea to Northern India and study the cultural exchange and its effects. Furthermore, we aim to use the above typology to revise the typology of the Korean traditional dresses that were formerly just sorted as a type of coat-trousers that classified as a nomadian Scythian dress type. The results of above analysis are as follows: The clothing of many tribes living in the coastal areas of Mediterranean Sea to the Northern India in the Achaemenid dynasty of Persia on 6th century B.C. shows that the typology of the dressings have close relationship with the region they live in. Such typology is displayed differently from tribes east and west of Iran. The tribes west of Iran showed characteristics of an agricultural tribe and the tribes east of Iran displayed features of a nomadic tribe. In addition, uniformed styles of dressing were displayed amongst many tribes sharing a common lineage. Such inference came from the fact that similar styles of dressings were identified not only in tribes east of Iran but also in tribes west of Iran.

Mathematics is the subject that requires high mental function such as the ability of logically thinking and investigating. Because of the reason there exists much greater difference in students' individual scholastic abilities in mathematics class than in other classes. Recently many schools organize students into two or three level-based mathematics classes according to each student's level to solve the problem. But in spite of its many merits the new system of class organization has some problems. The problem which is pointed out as the most serious thing frequently is that many teachers still use the same textbook and the same teaching method for all students, not considering student's level. Obviously it causes the reduction of students' interest and motivation. In this point of view, I tried to solve such a problem by development and application of level learning materials reconstructed text book according to students' abilities and levels through this research. As the result of the research to examine the changes of students' emotional factors such as the recognition, interest, and attitude which influence on improving self-educability in learning mathematics has occurred, the following conclusion comes out. 1. Through the mathematics class utilizing level learning materials reconstructed textbook, students come to recognize that level learning materials are more effective than uniformed contents of the same textbook and get more active learning attitude. 2 The application of level learning materials in a level-based class has contributed to increasing students' interest in mathematics. Furthermore it was also effective in the positive changes of students' emotional factors such as the recognition, interest, and attitude which influence on improving self-educability in learning mathematics.
