The article 49-2 of Industrial Safety Law requires that all the owners of industrial plants which contains dangerous facilities perform the process safety management. That is, this law requires the owners of industrial plants to take necessary measures to prevent fire, harmful gas leaking, explosion, and other serious accidents that could cause demage and injuries to the employees. So far, domestic chemical plants have tried to invest money and time in safety management. But, such efforts have been made only in chemical plants that were subsidiaries of large business groups. Moreover, since the economic crisis of Korea which is symbolized by the IMF bailout, small and medium size companies could not afford to invest in safety management. Their major concern is to increase productivity and thereby, survive in this crisis. The goal of this research is to develop the process safety management system that can help small and medium size companies to positively secure the process safety management. So, in developing the process safety management system, the financial and practical difficulties of such companies are fully taken into consideration.

Small firms are considered as the last mile in electronic networks of business enterprises. Since small firms lack in their resources and capabilities for IT deployment, it seems a challenging project to make them electronically linked to their trading partners. This study aims to investigate the factors that influence the intent of small firms to adopt electronic linkage to their trading partners. This study considers the context where small firms already have transaction relationships with partner firms and where their adoption of electronic linkage may influence the nature and performance of the transactional relationships. This study considers the expected value of electronic linkage and the joint actions of the trading firms as the major factors. Its research model also includes traditional factors such as influences from the industry and the trading partner, the support of CEO, and the readiness of the trading partner. Based on the survey data from more than 1000 small firms, the present study performs regression analysis and finds that all but one factor are significant in explaining the variations in the adoption intention of small firms. The exception is the joint action, which is shown to decrease the intention. Based on the results, this study offers business and policy implications that would be useful to business managers and policy makers.

인터넷과 웹의 발전은 쇼핑몰 형태의 B2C(Business to Customer) 전자상거래를 비롯하여 기업간의 거래에도 많은 변화를 가져오게 되었다. B2B(Business to Business) 전자상거래는 기업간의 거래를 위하여 이기종간의 데이터 교환은 물론, 다양한 응용 어플리케이션과의 연동이 필수적이다. 기업간 거래에 있어서 가장 기본이 되는 EDI는 그 동안 EDIFACT, X.12와 같은 표준을 이용하여 이루어져 왔지만, 확장성과 유연성이 떨어지고 개발 및 유지, 보수에 많은 비용을 요구하기 때문에 일반 중 소기업들까지 사용하기에는 어려움이 많았다. 반면에, 인터넷과 웹이라는 누구나 쉽게 이용할 수 있는 수단과 XML 기술이 등장하면서 이를 EDI에 적용하여 확장성과 유연성을 높이고, 저렴한 비용으로 EDI 시스템을 효과적으로 구축할 수 있게 되었다. 본 논문에서는 한국전력에서 사용하는 전기신규접수 XML/EDI 시스템 개발 경험을 바탕으로 XML을 이용한 EDI 문서 설계와 XSL을 이용한 문서 처리 기술, 레거시(legacy) 시스템과의 연동, 보안 및 인증 기술의 적용 등을 바탕으로 XML/EDI 시스템의 설계 및 구현에 대하여 논하고자 한다.

A preburner is one of the key components for a staged combustion cycle engine fueled by kerosene and Lox. Since it has oxygen rich combustion inside, temperature control is very crucial. The temperature of the exhaust gas should be low enough not to burn turbine blade and yet high to keep the efficiency high. In addition temporal and spatial deviations also managed strictly. Conventionally, the required average and maximum temperature are determined by engine system and the preburner should be developed to meet the criteria. Currently being developed preburner has 50K spatial temperature deviation requirement. It was estimated by numerical simulations and proven by tests. The numerical analysis were done with both supercritical condition and normal conditions. The tests results showed that the temperature deviations were less than expected, and the results from the test and simulations were well agreed when the supercritical conditions were considered. Above all, since the gas temperature created by the preburner is very stable with minimum deviation, the preburner developed can be used to drive a turbine and for gas-liquid combustion chambers.

This study was motivated by a practical need for estimating the macroeconomic effect of government IT Promotion investment, specifically for micro and small firms. Small firms have been in a disadvantageous position to adopt and utilize new IT compared with medium or large-sized firms. Small firms don't have enough resource to acquire IT in general, therefore private IT companies don't have much incentive to develop IT services and products for small firms. Lack of feasible IT solutions for small firms again restricted active IT adoption of small firms. Government recognized the vicious cycle, therefore decided to promote private IT companies to develop IT services and products for small firms's. Our main concern was to identify a relevant government supporting Policy, especially in the amount and the period. To do this, we first constructed a system dynamics simulation model to Investigate important factors and causal relationships among them. Simulation results showed 2.19% of GDP contribution and 0.16% of employment contribution in max from small firms' IT adoption. Also we could find that investing proper amount for a short period would be for better than maintaining Investing small amount for a long period.

고성능 다단연소싸이클 엔진은 산화제과잉 예연소기를 사용한다. 예연소기 후류에 위치한 배관 및 연소기 헤드 등은 고온/고압 산화제 과잉 환경에 놓이게 되며, 운용 조건에서는 국부적으로 온도를 상승시키는 외부 발화제에 의하여 녹는점보다 낮은 온도에서 재질이 발화될 수 있다. 따라서, 이러한 환경에 적합한 재질 및 코팅은 내산화성, 내인화성 및 자발화성도 중요하나, 외부 발화제에 의한 내발화성이 가장 중요한 특성이 된다. 여기서는 이러한 환경에 적합하며 지상 시험용 노즐 및 배관에 적용될 수 있는 재질 및 코팅에 대하여 조사한다. 러시아는 이미 이러한 환경에 적합한 재질 및 코팅들을 개발하여 RD-170, 180에 적용 중이다. 그러나 미국은 최근에 이러한 연구를 시작한 것으로 추정된다. 따라서 자료 접근이 가능한 범위에서 러시아의 재질 및 코팅을 조사하며, 미국 자료에서는 산소 시스템 안전 등과 같이 간접적인 자료들을 통하여 대체가 가능한 후보 재질 및 코팅을 조사한다. 다단연소싸이클 연소시험 배관에 적용할 수 있는 방법은 다음과 같다. 코팅 없이 Monel K500을 사용하거나, OFHC 혹은 Ni 라이너에 고강도 외피를 사용하는 방법이 있으나, 두 방법 모두 재질의 가격 및 수급, 라이너 적용 방법 등이 어려울 수 있다. 국내에서 산화제과잉 가스 환경에서 적용할 수 있는 법랑을 개발하거나 수급이 용이한 법랑을 찾아 오스테나이트 스테인리스강에 적용하는 방법이 있다. 이 방법은 외부 발화제에 대한 내발화성을 증가시키는 경제적이고 용이한 방법으로 판단된다.
