This paper presents a conceptual model as a new framework of the technology development processes in LDCs based on global perspective. The proposed model consists of three development stages such as initiation, internalization, and generation, as well as some propositions related to the levels of transferred technology, technology acquisition modes, technology elements mastered, and major contributors of technology development in each development stage. The model explains several dynamic changes in LDC`s development processes with global perspectives focussing on the DC-LDC linkages. In addition to formal channels, this model also deals with non-formal channels, including imitation, which are unduly neglected in the literature, equally important as methods of technology acquisition. Moreover, the proposed model analyzes the technology development processes from several different standpoints and embraces multi-level units of analysis such as country, industry, firm, and unit technology. Because the proposed model explains the observable phenomena only and is a conceptual model to be tested, further theoretical studies are needed to explain the underlying principles of technology development in LDCs such as the technology learning theory. In addition, further empirical studies to test the global perspective model in various situations are needed.

This paper discusses distributed processing systems to be applied to design the Education and research Computer Network. Especially, we have analyzed performance measures of computer communication networks, have solved the capacity assignment problem approximately, and have presented two algorithms by which we could decide the efficient topology of a computer communication network. In general, computer networks can be modelled by appropriate queueing models on the basis of queueing theory. But in that case we must consider several performance measures carefully to estimate the performance of the model of a computer network. In this paper, we have analyzed some important performance measure - time delay, line cost, and routing strategy. According to queueing theory, we can get optimal solutions of the network optimization problems. However, if we are to use this method we should know a great deal of data, and so it is time-consuming to find the analytic optimal solutions. In this paper, we have introduced the inefficient index(I) to describe another method - approximate method - of solving the capacity assignment problem. Meanwhile, we have presented two algorithms by which the efficient network topology can be extracted. In other words, this paper has shown construct the Education and Research Computer Network, which is one of the Five Main National Computer Networks, and we can expect it might be applied to the implementation of other computer networks. the design method of the network topology satisfying suitable utilities and costs of processors, which are components of a computer network, under the given design constraints. With applying those algorithms to the computer network including several distributed database systems, we have presented a case study. In conclusion, this paper has provided a theoretical background to

Korean econmy now faces necessity of accepting and realizing economic democratization because of seething national desire for higher wage and better welfare as well as even widening gap between the haves and the have pots which has been resulted from the quantitative economic growth. The purpose of this paper lies in suggesting measures of activating small businesses which are relatively more vulnerable than big businesses through technological innovation. This paper has studied the concept importance, characteristics, present situations, and supporting systems of technological innovation in small businesses. It also has reached the following conclusion as measures of activating small businesses through technological innovation. 1. Organization of research and establishment of measure for lack of manpower 2. Establishment of technical guidance departments classified by industry in the Federation of small business 3. Reinforcement of Industrial Technical Supporting Center 4. Establishment of optimal technical development systems 5. Expansion of investment in technical development 6. Promotion of market demand

The general approach adopted in presenting this thesis was an attempt to clearly identify both the depth of diversification of management pursued by the general trading companies of Korea during the five years between 1982 and 1986 and the degree of its impact upon the managerial performances. In formulating this problem I attempted to pinpoint the scope of different impacts upon the managerial performances made by the general trading companies of Korea, and exposed the problems created in the relationship between the diversification strategies and the managerial performances through theoretical and empirical analysis of the cause and effect relationship and a suggestion is made to improve the problem. Thus, the final purpose that this thesis attempts to achieve is to develop a new model for the diversified strategies that can be adopted by the general trading companies of Korea. The development of such a new model was made possible through an intensive research made on the possibility for the diversification of trade regions, products and functions. At the same time, the relationship between the systematization of subsidiaries of a business group and the business growth as the result of managerial performances as well as the relationship between business stability and business profit have also been analyzed for that purpose. In order to collect various data on the diversification strategies and the managerial performances made by the general trading companies of Korea, eight general trading companies were selected as the targets of my primary data research, and a personal interview with the top management executive was conducted, thus performing a field survey with questionnaires delivered. In addition, supplemental collection of data to augment insufficient research materials was made through various publications and statistics which were made available at Korea Traders Association, the Ministry of Commerce and Industry, Korea Business Information Institute, and Korea Institute for Economics & Technology. In order to collect research data on the general trading companies of Japan 1 made a trip to Japan and stayed there for 40 days. During my stay in Japan I was fortunate enough to get all the data needed for my research work. Included are the reports on the securities of nine SOGO-SHOSHAs and the data materials published by several SOGO-SHOSHAs of Japan, which were made available through the data reference rooms of Waseda University and Nomura Research Institute in Tokyo City. In this thesis, two hypothetical theses of I, and II are proposed, taking advantage of the method of statistic analysis through the quantitative data materials secured as above, the methods used to test the two hypotheses are plot chart observation method and stepwise multiple regression analysis method. The former is used for hypothesis I and the latter is used for hypothesis II. For the statistic streatment SPSS-Version X was used. The conclusion of this thesis may be summarized as follows; As an enterprise grows bigger both in size and scope it is bound to be internationalized, looking for new chances of business. The general trading companies of Korea can not be the exception and so, they have kept expanding their business by accelerating internationalization. They launched the diversified strategies as a means of dispersing business risks. There are four ways by which diversification of business management can be made. Namely, I) diversification of trade regions 2) diversification of products 3) diversification of function 4) systematization. The effect that can be expected from such diversified strategies depends on the managerial performances made by each diversified strategy. In other words, the diversified strategy for trade regions is the business strategy to be employed by the general ,trading company which is oriented toward the growth of business, whereas the diversified strategy of products should be followed by the general tradin
