It is widely known that KMS (Knowledge Management System) plays a role of facilitator that contributes to upgrading the organizational performance. Despite this widespread belief, actual operation of KMS has been stalled at the level of being used only for the plain knowledge administration, not reaching the level of utilizing KMS strategically. In this sense, this case study suggests three successful KMS operation strategies-personalization strategy, socialization strategy, and technological strategy. Cases adopted in this study include HIRA(Health Insurance Review & Assessment Service) and KORAIL (Korea Railroad) where KMS has been successfully utilized to improve their organizational innovation and performance as well. Through scrutinizing the two cases, it was concluded that the proposed three KMS operation strategies have potentials of being generally applied to other KMS operation cases.

In general, most incomplete communication link setup between satellite and ground station right after separation from launcher come from less accurate orbital vector ground station uses to track the satellite because only predicted orbital state vector is available during first few orbits. This paper describes the developed procedure for successful initial acquisition for KOMPSAT-2 using scanning functions ofK13 antenna system with predicted orbital information. Azimuth scan, raster scan, spiral scan functions were tested with KOMPSA Tl under intentionally degraded orbital information for antenna operation. Through tests, spiral scan function was decided to be best search scan among 3 scans. Developed procedure can assure the successful acquisition only if azimuth offset and time offset value are within +/-2deg and +/-30sec, respectively.

The variations of performance and metabolites at an early stage were investigated for the successful start-up technology in continuous fermentative hydrogen production. Unsuccessful start-up was observed when the operation mode was changed from batch to continuous mode after the yield was reached to 0.5 mol $H_2$/mol $hexose_{added}$ by batch mode. $H_2$ production continued till 12 hours accompanied by butyrate production, but did not last with propionate production increase. It was suspected that the failure was due to the regrowth of propionic acid bacteria during batch mode which were inhibited by heat-shock but not completely killed. Thus, successful start-up was tried by early switchover from batch to continuous operation; continuous operation was started after the $H_2$ yield was reached to 0.2 mol $H_2$/mol $hexose_{added}$ by batch mode. Although $H_2$ production rate decreased at an early stage, stable $H_2$ yield of 0.8 mol $H_2$/mol $hexose_{added}$ was achieved after 10 days by lowering down propionate production. And it was also concluded that the reason for $H_2$ production decrease at an early stage was due to alcohol production by self detoxification mechanism against VFAs accumulation.

Purpose - The objective of the current research is to explore success factors of the 'Night Markets' in Korea. Unlike other countries, where the markets are culturally established based upon various socioeconomic factors, the night markets are relatively new phenomena in Korea and are created by the government's support. Since the first introduction in 2011, now there are 34 Night Markets that are operating or are in the process of operation. Some of them attract nearly 100,000 customers a day, while some are discontinued shortly after the introduction due to lack of visitors. Its influence on the customers' behavioral motives of engaging in various activities in the night markets is increasing. However, because of its brief history in Korea, not much of research has cast attention on them. It is imperative to figure out the success factors of the night markets, so that other night markets can learn the secret of successful operation of the markets. Research design, data, and methodology - The research is based upon both qualitative and quantitative data. Data are collected from multiples levels of the night market related parties. Four groups are chosen: customers, night market sellers, sellers' union and government officers who are in charge of the market. Conventional survey formats are employed for customers and night market sellers. For night market union and government officers, survey and in-depth focus group interview methods are applied. Of the night markets in operation, commonalities of successful or well established ones are elaborated. Results - Night Market operation success factor are sought utilizing Porter's The Competitive Advantage of Nations model (1990). Results are shown that successful night markets commonly have satisfactory 'Factor Conditions.' Specifically, established night markets have either nearby big cities or tourist attractions in common. While these have fair 'Firm Strategy/structure/rivalry,' and 'Related and supporting industries,' they commonly demonstrate weakness in 'Demand conditions.' Conclusions - A successful night market incurs new customers not only to the market itself but also to the traditional periodical market the night markets are within. Government support to the night market can be justified where the circulation of new customer to the night market and the night market to the periodical market mechanism is in effective.

최근 국가의 경쟁력 확보를 위하여 사회간접자본시설에 대한 투자가 급증하고 있으나, 민간투자사업은 정부의 재정부담 증가, 잘못된 수요 예측 등 여러 측면에서 많은 문제점을 드러내고 있으며, 이러한 문제점들은 결국 민간투자사업의 확대 및 성공적 추진에 걸림돌이 되고 있다. 이러한 환경 속에서 최근의 국내 건설업계는 제한된 공공부문의 턴키와 BTL 사업을 두고 매우 치열한 수주경쟁을 벌이므로써 건설업계의 경영난을 가중시키고 있다. 더욱이, 이러한 경쟁은 업체 간의 건설원가에 대한 가격 경쟁까지 야기시키므로서 BTL사업 시 기본적으로 고려해야 할 원가의 정확한 견적, 업체의 능력, 공기 등 사업의 성공여부를 판가름하는 기본적인 검토사항마저 무시되고 있는 형편이다. 이에 본 연구는 BTL사업의 핵심성공요인과 효율적인 운영방안을 제시함으로서 국내 건설기업이 BTL 사업 참여시 합리적인 전략을 수립하는데 기초적인 자료를 제공코자 한다.

Downcoiler is one of the major facilities in hot strip mill operation. The key to good coiling is having good equipment, modem control systems, excellent maintenance and an understanding of coiling process. Therefore, this study aims to develop a program that is useful for calculating machine design parameters and simulating coiling process. In this study, the pinching and coiling mechanism of the downcoiler was thoroughly studied and some of operational factors and their effects on the coiling process were investigated. The software was developed to estimate engineering parameters for coiler component design and to determine optimal setting values for successful coiling operation. In order to check the accuracy and usefulness of the developed software, the simulation of the downcoiler in $\#2$ Hot Strip Mill in Pohang Works was performed. The simulation results suggested that the set-up value for unit tension could be lowered. Test coiling operation by using the lowered set-up value for unit tension resulted in much more successful coiling in the aspect of strip quality and power consumption.
