The purpose of this study lies in identifying Korean scientists' dependency on foreign scientific and technical information (STI), with emphasis on investigating the causes and results. Especially, this study intends to investigate the impacts that a growing dependency on foreign STI might have brought and will bring about on the development of indigenous STI in ROK. To the end, the present discussion covers the following specific research questions: 1) what are the major information sources used by Korean scientists to locate STI necessary for research-related activities\ulcorner 2) to what extent do Korean scientists use foreign STI for research-related activates, as compared to the use of domestic STI\ulcorner 3) what are the major factors causing the information dependency among Korean scientists and what are the results of the growing information dependency\ulcorner And finally, 4) what suggestions can be made for ROK to further its indigenous STI development, while minimizing its dependency on foreign STI\ulcorner Survey method, together with citation analysis method, is employed as the major data collection technique. The survey sample consists of 167 most 'representative' Korean scientists selected on the basis of their research productivity. 167 specially-designed questionnaires were mailed and 104 out of 167 were responded. Follow-up interviews were carried out for 32 out of 104 respondents, who returned the questionnaire but did not answer some specific questions. The data collected from these 104 respondents were analyzed on the basis of two distinguished groups namely, junior and senior scientist groups. Among the 104 respondents, 58 a n.0, ppeared to belong to a group of senior scientists (older than age 45 and finished their final degrees since 1980), and 46 belonged to a group of junior scientists (younger than age 45 and finished their final degrees before 1980). The major findings of the present study include: 1) Korean scientists regard 'scientific and technical journals and books'as the most important information source to obtain the recent STI; 2) their dependency on foreign STI, for the purposes of research and teaching, is extremely high (information dependency for research activities is 88.5%, and that for teaching activities 91.2%); 3) the information dependency of junior scientists are higher than that of senior scientists; 4) Korean scientists' growing information dependency is closely related to both small quantity and low quality of domestically-produced STI, and has a statistically significant relationship with their educational background; and finally, 5) in order to theoretically explain the growing information dependency of Korean scientists, a hypothesis - 'chronic cycle of information dependency' was developed and introduced. The present study suggests the promotion of indigenous STI as a desirable alternative to escape from the 'chronic cycle of information dependency. Localization of the imported foreign STI is suggested as a good strategy for the indigenous STI development, and also suggested are STI policies for both success of localization process and promotion of more efficient STI flows at national and international level.

A major topic in the field of network and telecommunications is doing business on the Word Wide Web(WWW), which is called Electronic Commerce(EC). Another major topic is blending Artificial Intelligent techniques with the WWW. To provide customer with the information of goods in suit with a customer liking, we propose multi agent system which is consist of customer agent and search agent etc. Also we use case-based reasoning for customer liking searching the information of goods and training through the reuse. This reuse make efficient management of information and a process of operation. In the relation between customer and goods, if there are some goods which is not search from case-base reasoning, we calculate satisfaction function for customer purchase goods. And to provide customer with the information of goods in the first of satisfaction function, This EC system can always provide the information of goods which is satisfied to customer.

Information obtained through various sensors embedded in a smartphone can be used to identify and analyze user's movements and situations. In this paper, we propose two rule-based motion detection systems that can detect three alphabet motions, 'I', 'S', and 'Z' by analyzing data obtained by the acceleration and gyroscope sensors in a smartphone. First of all, the characteristics of acceleration and angular velocity for each motion are analyzed. Based on the analysis, two rule-based systems are proposed and implemented as an android application and it is used to verify the detection performance for each motion. Two rule-based systems show high recognition rate over 90% for each motion and the rule-based system using ensemble shows better performance than another one.

In this study, we analyzed the information asymmetry and the agency problem in major affiliated companies on the basis of the R&D investment. As a result of comparing how the R&D investment effects on major affiliated companies and the independent companies, even the achievement of R&D investment effects in a positive way to the firm value, the positive effect appears much lower on major affiliated companies comparing independent companies. In order to analyze the case, we investigated in a separate way according to the shareholding ratio and the affiliated market using the sample of the independent company and the group affiliated company. As a result of such analysis, the cause of this comes from the agency problem in major affiliated company, not the asymmetry information of affiliated company. After we analyzed the sample of the research depending on the affiliation market, we could observe there is a little impact of the asymmetry information in the outcome of the R&D investment of the major affiliated companies. In contrast, the companies which rated lower in the ratio of the shareholding appears much less in the positive effect of R&D investment compared to the companies which rated at a higher level. This phenomenon was also consistently observed when changing the research method or further subdividing the sample of companies belonging to the group based on the ownership share of major shareholders.

The feasibility of graphoepitaxial growth of compound semiconductor has been studied. Two kinds of substrates were prepared; one is smooth substrate, the other one is a periodic structured substrate. ZnO film was deposited on both substrates by sputtering, and thermal treatment was performed to improve the crystal quality and investigate the effect of the periodic structure. Atomic force microscopy (AFM) and photoluminescence (PL) were used to characterize the samples. As a result, very similarchange, the improvement of crystallinity, has been observed from both samples, except the sample annealed at the highest temperature. It implies the periodic structure affects the crystallinity of the films, and the graphoepitaxy of compound semiconductors is possible by using appropriate surface structure.

In line with the social changes due to the Fourth Industrial Revolution, foreign countries are strengthening information education for the future of education. This study analyzed the current status of software (SW) and artificial intelligence (AI) education among different types of information education programs in elementary schools of major foreign countries, and compared them with the education provided in Korea. Compared to major foreign countries, Korea allocated very little time for software education in elementary schools, making it difficult to sufficiently cover all areas of the curriculum achievement standards. In addition, other countries recognized the importance of artificial intelligence, an important technology of the Fourth Industrial Revolution, and were providing artificial intelligence education on the basis of software education at the national level. The Korean government is also planning on providing the education at national level, but it was identified that the information education of elementary schools have many problematic issues. This study emphasized the need to establish an information curriculum for elementary schools as a way to address these issues.

The purpose of this study is to investigate aspects of office information systems in japanese corporations in order to understand introduction strategies and to find out whether strategy elements could be transferred to Germany. In this study, three points of view played an important role. (a) Technological and infrastructural support systems What kind of role did the liberalization of telecommunication markets and the avaliability of computer hardware play to help develope of database industry and implement office information systems? (b) Strategies and forms of the implementation of office information system: Which strategies were successful, distribution or centralization? How were technical and organizational problems handled? (c) Process of data communication : How did the implementation of office information system change the data communication with in-house or commercial database systems? To answer these questions, this study centered around a two-step field research in Japan. (1) Screening stage: to gain a general overview of office information system in Japan. The results of this initial research have been analysed and carefully evaluated to prepare for the second and major part of field research in Japan. (2) Data collection stage: interviews with respective managers, heads offices, and data processing units in 20 enterprises. The major results of this study are as follows. Today in Japan, office information system is understood as the interconnection of the in-house and commercial database for the maximization of the use of information resource In an organization. In particular, developments in the direction of distributed systems and the 'intelligent office' by means of the new information and communication technologies are very important.
