Since the outbreak of COVID-19, 'overcoming infectious disease' has emerged as a priority task for most policies. Each country has implemented policy programs to significantly shorten the vaccine development period with the goal of rapid vaccine development. This study judged this process to be a shock to the existing social and technological system and its recovery. Accordingly, the United States' Operation Warp Speed, CEPI's 100 days mission, and Japan's SCARDA were selected as examples of policy programs with 'rapid vaccine development' as their mission and analyzed difference from traditional vaccine development system in terms of rapid development. As a result, it was confirmed that the accumulation of innovative resources was shared as the key to achieving the mission in the preparation stage before the outbreak of an infectious disease. However, it was also possible to discover an approach to shortening the period of each stage without fundamentally changing the vaccine development structure itself.

Recently, in the bio-field success stories of ventures through a biosimilar technology is being excavated. but the growth of ICT industry has been stagnant since reaching a boom in the dissemination of early high-speed internet in 2000s. The purpose of this study is to explore the factors of change of business model and business strategy of ICT ventures and SMEs with the evolution of the digital ecosystem, and to drive the factors to be competitive on the global value chain. The researcher selected an entreprenuership, market-innovation orientation, technology-innovation orientation, and Administration-innovation orientation as internal factors influencing the global competence and healthiness of the ecosystem as external factors. The researcher applied samples of 94 ICT Venture and SMEs to a research model, and adopted 5 hypotheses. The researcher believes that only a few hypotheses were adopted because it takes time for overall innovation orientation of ICT Venture and SMEs to result in the real global competence as the their innovation orientation is still on the level of domestic market. And the researcher also thinks that only healthiness of the ecosystem affected management performances because the companies' performances of the last 3 years were so weak that the correlation between innovation orientation of each company and the performances were not big enough.

아키텍처 혁신은 급진적 혁신과 달리 기술적 불연속성의 정도는 낮지만 제품 아키텍처의 변경을 통한 기술적 성능개선 폭은 큰 혁신으로 이해되고 있다. 신생 산업의 초기, 급진적 혁신 제품의 개발에 성공한 기업은 이후, 열등한 아키텍처 효율성 문제를 극복하지 않으면 더 이상 기술적 성능 개선이 둔화되는 시점에 도달하게 된다. 이 지점에서는 급진적 혁신 단계에서의 열등하지만 창의성이 깃든 제품 아키텍처의 창출 경험은 오히려 아키텍처 혁신의 장애물로 작용하게 될 수 있다. 본 연구는 아키텍처 혁신 전후의 시장 요구변화와 이에 대한 기술적 해결 전략을 단계모델의 관점과 문제해결 모델의 관점이 결합된 분석틀의 구축을 통해 이해해보고자 하였다. 한국의 중소기업 자화전자(주)는 산업 초창기 휴대폰에 장착되는 진동모터의 급진적 혁신에 성공 후 아키텍처 혁신과 연관된 장애물들을 극복함으로써 마침내 자신이 개발한 진동모터의 본격적 확산에 성공할 수 있었다. 본 연구는 진동모터의 개발과정에 대한 능동적 참여관찰을 통해 단일 사례를 종단적으로 깊이 연구함으로서, 이 과정이 어떻게 진행되었는지를 이해하고자 하였다.

A strategic planning to attain a Marine Logistic Transportation Center on the Far-Eastern Pacific is investigated and is being reviewed at the NTRM Vision IV. Utilizing high speed super-sized container carriers, 15,000TEU and 35knots, between the two hub-ports, a western coast city of the United States and Kwangyang/Busan of South Korea, are motivated by now highly successful shipbuilding and maritime industries. SMART, 330MW thermal power plant under planning, will greatly expedite the transfer of cargoes across the Pacific. A sizable effort is required to achieve the goal, but the reward will also be very great, technically, economically, socially and geo-politically.

High speed railroad project management has been almost completed by starting operation of Seoul-Busan high speed railroad with the exception of a few constructing blocks currently in April, 2004. After Korea Rail Network Authority was established in 2004, it needs to develop new project management system for both conventional railroad construction and high speed railroad construction for domestic railroad projects, while it plans to invest in overseas railroad project for logistics innovation and improvement in passenger transport services on a large scale. Therefore this paper provides the method that we can adapt the project management system for high speed railroad containing experiences and know-how from construction of high speed railroad for both conventional railroad construction and high speed railroad construction or improve project management system for high speed railroad to use it as project management system for overseas railroad projects.

The purpose of this study is to analyse the diffusion process of personal computer (PC) in Korea during the 1990's. To achieve the goal, five research steps have been done such as the literature survey of diffusion theory, set-up of theoretic equilibrium model of supply and demand, derivation of an equilibrium path using Hamiltonian, and empirical analysis. The empirical analysis has been performed based on that equilibrium path. The results can be summarized as follows : First, technological attribute of diffusing product influences the diffusion speed of Product. It has been proven that the size of the network has a significant effect on the diffusion of PC in empirical study Second, supply factors have an important role in the diffusion process. According to the empirical analysis, decreasing cost of production as a result of technological advance promotes the speed of diffusion. This point seems to be manifest theoretically, but existing empirical models have not included supply factors explicitly, Third, it has been found out that expectation of decreasing cost would influence the speed of diffusion negatively as expected ex ante. Theoretically this result is supported by arbitrage condition of purchasing timing.

We proposed several systems for 1Giga bit Modem. The first, Binary ASK(Amplitude Shift Keying) system has a high speed shutter transmitter and no IF(Intermediate Frequency) receiver only by symbol synchronization. The advantage of proposed system is that circuitry is very simple without IF process. The disadvantage of proposed system are that line spectrum occurs interference to other channels, and enhancement to 4-level system is impossible due to its large SNR degradation. The second, Binary phase modulation system has a high speed shutter transmitter and IF-VCO(IF-Voltage Controlled Oscillator) control by base-band phase rotation. Polarity of shutter window is changed by the binary data. The window should be narrow same as above ASK. The advantage of proposed system is which error rate performance is superior. The disadvantage of proposed system are that Circuitry is more complex, narrow pull-in range of receiver caused by VCO and spectrum divergence by the non-linear amplifier. The third, 4-QAM(Quadrature Amplitude Modulation)system has a nyquist pulse transmitter and IF-VCO control by symbol clock. The advantage of proposed system are that signal frequency band is a half of 1GHz, reliable pull-in of VCO and possibility of double speed transmission(2Gbps) by keeping 1GHz frequency-band. The disadvantage of proposed system are that circuit complexity of pulse shaping and spectrum divergence by the non-linear amplifier.
