Today scientific and technological activities for development raise a whole series of problems with the institutionalization and the professionalization of science, but also with the increasingly obvious links between technologies, innovation and production of goods and services, and the difficulties caused by relationship between sovereign one. Solving these problems therefore requires discussion, agreements, and consensus, not only with the Korean Government, where present budget difficulties demand trad-offs between scientific and technological activities and other forms of technical assistance on the one hand, and other R&D objectives on the other. The purpose of this paper is to examine the problems facing auther's own experiences in this connection and to show what kinds of solutions they have been applying in order to identify some useful inputs through consulting engineer for discussion. It is based on very general accounts of the policies, institutions and activities of about own experiences and, even for those, only on rather limited, fragmentary information derived from the few official documents.

This Paper analyses characteristics of the numerical controller industry in market formation and the flow of information between users and producers and the characteristic of knowledge base of the industry and discusses the difficulties derived, from the characteristics, in accumulation of technological capability In market formation between users and producers, the multi-layered market is not favorable to domestic producers in that lower end market is not large enough to provide cradle market to them which produce inferior quality and lower price than imported products. The credibility of the performance of a product is difficult to prove until a critical mass of products are sold. Therefore gaining market share is deterred by unproven credibility of the performance of the product. The flow of information between users and producers is limited. The flow of information on users environment through mass market to producers is essential for improving credibility of a product. The nature of knowledge base is tacit and the means of knowledge transmission is limited. Technological licensing and reverse engineering, which have been conventional means of knowledge transmission, are not useful in the numerical controller industry. These characteristics provide conditions of vicious circle in accumulation of technological capability of the numerical controller industry. It is conjectured that these characteristics are derived from the fact that the numerical controller is the result of IT based technological convergence in controlling machining process. This paper argues that these characteristics of the industry challenges existing approach to R&D management and framework of science and technology Policy.

After the IMF jurisdiction period, the Korean economy experienced a venture boom. Korean venture enterprises had been recognized that high profitable and high technology capacity based. These ventures also have contributed to national added value tolerably. In particular, Korean information technology (IT) venture companies got away the order of economy concentrated big companies, which were taken the opportunity of new economy to make suggestion of the future courses and to open an e-Korea era. However, IT ventures firms or dotcom enterprises have had difficulties through sinking down their bubbles and slumping technology sector from the first half of the 2000. In consideration of Korea IT venture companies' conditions, Korean government introduce new national vision in order to go ahead of intelligence based society form knowledge based. Korea is planning new investment to meet with the challenge of globalization proactively by national band named u-Korea. As following a step in IT infrastructure, it will give Korean IT ventures new demand creative technologies and services by new technological windows of opportunity. This situation is expected that will become an economic take-off. This paper will look for the way to stimulate Korean IT ventures' competence and present new frontier of IT ventures turnaround.

Many Korean companies wanted to improve technological competitiveness and business performance radically through technology leadership initiatives. In-depth case studies about successful Korean technological innovation in the technology generation stage have potential to minimize Korea and developing country firms' trial and error when they are pursuing new technological innovation in the technology generation stage. There are few studies about developing country firms' technological innovations in the technology generation stage and especially process innovation studies are far less performed compared to product innovation studies. This is an exploratory study of POSCO's FINEX process technology innovation in the technology generation stage. These are my findings from this study. Firstly, leadership innovation in the technology generation stage is not a continuous development of catch-up innovation in the technology internalization stage and only top managements can initiate highly risky leadership innovation. Secondly, developing country firms which lacked in technological capability overcomes difficulties in the early stage through complementary technological collaboration with R&D first-movers. Thirdly, this company become a technology leader in spite of late entry in technology development race with developed country firms through rapid scale-ups.

Experimental investigations were carried out on an Axi-symmetric Body Model fitted with Pump-jet Propulsor (PJP) in the Cavitation Tunnel at Naval Science and Technological Laboratory (NSTL). The tests were intended for evaluating the propulsion characteristics of the body and propulsor. The self propulsion point of the model for two configurations was determined after finding the corrections for tunnel blockage effects and differences in model length at zero trim. The results were found to match closely with the towing tank results. The rotor and stator torques also matched closely over full range of experiment. Further experiments were carried out on the body at $4.5^{\circ}$ angle of trim to investigate the propulsive performance and assess the operational difficulties in the sea. The results indicated an increase in resistance and decrease in rotor thrust; but the balance of torques between the rotor and stator was undisturbed, causing no concern to vehicle roll.

This paper analyses characteristics of the numerical controller industry in market formation and the flow of information between users and producers and the characteristic of knowledge base of the industry and discuses the difficulties derived, from the characteristics, in accumulation of technological capability. In market formation between users and producers, the multi-layered market is not favorable to domestic producers in that lower end market is not large enough to provide cradle market to them which produce inferior quality and lower price than imported products. The credibility of the performance of a product is different to prove until a critical mass of products are sold. Therefore gaining market share is deterred by unproven credibility of the performance of the product. The flow of information between users and producers is limited. The flow of information on users environment through mass market to producers is essential for improving credibility of a product. The nature of knowledge base is tacit and the means of knowledge transmission is limited. Technological licensing and reverse engineering, which have been conventional means of knowledge transmission, are not useful in the numerical controller industry. These characteristics provide conditions of vicious circle in accumulation of technological capability of the numerical controller industry. This paper argues that these characteristics of the industry challenge existing approach to R&D management and framework of science and technology policy.
