        본 연구에서 우리는 국가문화의 기술혁신활동에의 영향을 탐색해 보았다. 먼저 (국가)문화의 개념을 정리하였고, 다양한 세부 국가문화지표들에 대한 논의도 추가하였다. 다음으로 국가문화가 기술혁신 활동 및 성과에 영향을 미치는 이론적 메커니즘을 기존 문헌 을 통하여 정리하였다. 국가문화는 국가 사회를 구성하는 근저를 이루는 틀을 형성하는 다양 한 개념을 종합한 것이기 때문에 각 개념별로 기술혁신시스템에 미치는 영향은 크게 다름을 알 수 있었다. 마지막으로 국가문화가 기술의 특성, 사회제도, 정책 등과 어떻게 상호작용을 하면서 기술혁신활동에 영향을 미치는 지를 탐색해 보았다. 관련 문헌, 이론 및 실증분석을 정리하면서 동시에 이에 기반 하여 새로운 논의를 제안하고 다양한 미래연구 가능성을 제시 하였다. 이를 통한 기술혁신이론에의 시사점도 정리하였다.

        We have developed a data integration system for ground-based space weather facilities in Korea Astronomy and Space Science Institute (KASI). The data integration system is necessary to analyze and use ground-based space weather data efficiently, and consists of a server system and data monitoring systems. The server system consists of servers such as data acquisition server or web server, and storage. The data monitoring systems include data collecting and processing applications and data display monitors. With the data integration system we operate the Space Weather Monitoring Lab (SWML) where real-time space weather data are displayed and our ground-based observing facilities are monitored. We expect that this data integration system will be used for the highly efficient processing and analysis of the current and future space weather data at KASI.

        Four plasma instruments are currently under development for KAISTSAT-4 (K-4) which is scheduled for launch in 2002. They are the Solid-State Telescope, Electro-Static Analyzer, Langmuir Probe, and the Scientific Magnetometer, that will respectively allow in-situ detection of high energy and low energy components of auroral particles, ionospheric thermal electrons, and magnetic field disturbances. These instruments, together with the Far-ultraviolet IMaging Spectrograph, will provide micro-scale physics of Earth's polar ionosphere with detailed spectral information that has not been previously achieved with other space missions. In this paper, we review the concept of the four space plasma instruments as well as the anticipated results from the instruments.

        While it is well known that space environment can produce spacecraft anomaly, defining space environment effects for each anomalies is difficult. This is caused by the fact that spacecraft anomaly shows various symptoms and reproducing it is impossible. In this study, we try to find the conditions of when spacecraft failures happen more frequently and give satellite operators useful information. Especially, our study focuses on the geosynchronous satellites which cost is high and required high reliability. We used satellite anomaly data given by Satellite News Digest which is internet newspaper providing space industry news. In our analysis, 88 anomaly cases occurred from 1997 to 2008 shows bad corelation with Kp index. Satellite malfunctions were likely to happen in spring and fall and in local time from midnight to dawn. In addition, we found the probability of anomaly increase when high energy electron flux is high. This is more clearly appeared in solar minimum than maximum period
