Trade Portal Site(TPS) is one of the essential tools which can make it possible for small and medium enterprises(SMEs) to perform international trade activity more efficiently using newest information and communication technology including the Internet. Therefore, Korean SMEs need to utilize TPS more actively to enhance their export competitiveness. In this context, this article analyzes the determinants of export performances of Korean SMEs in utilizing the service of TPS based on the Service Quality Model. As a result of an empirical research by using regressive analysis, various measures of service reliability such as reliability, empathy, and tangibilities have positive effects on SMEs export performance in utilizing TPS. These results provides many useful implications to the TPS managers, e-trade related government agency, along with managers of SMEs using TPS.

In this study, it was mainly focused on the mechanism and reliability performances of PI/PET composites after many times of curving. We developed a new process of spacer for flexible display to improve the maintenance of cell gap. This new process used the laser carving technology, which is widely applied on printing press, to produce the pattern of spacers and shaped both of the alignment film and spacers simultaneously by press of pattern. Assembling the spacer-shaped film and plastic substrates together well and it shows an excellent performance on the maintenance of cell gap and reliability of curving.

We categorize quality management practices as two factors ; 'infra factor' and 'process factor.' We confirm the factors' statistical significance with empirical investigation about 167 manufacturing companies in nationwide. Moreover, we find the two factors affect positively on the manufacturing capabilities of differentiation and reliability, and on the performances as improving products and process. We prove these results with empirical method of structural equation model and AMOS program.

The suspension insulators are subjected to harsh environment in service for a long time. Long term reliability of the insulators is required for both mechanical and electrical performances. We studied an analysing method to find out a deformation of brittle porcelain with a thermal expansion of simulation analysis and experimental results show that cement volume growths affect severely to b mechanical failure ageing.

Protection and control systems play a prominent part in avoiding power delivery interruptions and help to get a fast and secure restoration when a failure occurs. In order to meet the higher functional requirements on modern power system, protection speed, selectivity, sensitivity, dependability, and security are essential to ensure reliability. These functions on be satisfied by taking advantage of microprocessor and communication technologies, and digital protection relays (systems) have been developed and applied to real power system enhancing reliability and saving money. It is necessary to have a tool to analyze the functions and algorithms of digital relays for installing them to power system. The purpose of this study is to develop a digital relay simulation program to estimate digital relay performances during system faults. Components of digital protective relay including analog filter, sampling unit, digital filter, and relay logic are modeled in this program.

Test evaluation field of railroad system that safety and reliability are important is to verify basic performances of unit products and system that were producted according to the specifications. Also, it is important works that verify finally in respect to commercialize verifying reliability and safety. As one part of system technology, this field is to construct database based on know-how of accumulated technology till now than high technical idea and, is to construct test evaluation system of railroad system that can utilize the constructed database. According to the necessity, our researchers investigated good measuring system of foreign country and performed research on performance test and evaluation technology of high-speed tilting vehicle that suits to domestic state.

본 논문은 한국 관광기업의 경쟁우위요인이 과연 해당기업들의 경영성과에 어떠한 영향을 미치는 가에 대한 실증연구이다. 즉, 한국의 수도권 및 경남권에서 경영활동을 수행하고 있는 관광기업들의 기본적인 현황과 문제점을 파악하고, 이어 FTA환경이라는 기회와 위협의 요인을 어떻게 적응하여 경쟁우위를 강화시키며 그들 자신의 경영성과를 제고할 것인가에 대한 연구인 것이다. 한국 관광기업의 경쟁우위는 일반적으로 중요하게 인식되고 있는 마케팅, 제품개발, 서비스 공급, 재무, 그리고 조직문화 등의 요인 등으로 분류하였으며 이들의 요인들이 경영성과에 미치는 영향력을 살펴보기로 한다. 종속변수인 경영성과는 매출, 이윤, 경영만족도로 분류하였다. 이들 간의 원인 관계를 실증적으로 분석하기 위해 구조방정식모델링 기법을 사용하였다. 분석 절차를 요약하면, 선행연구를 통해 문헌분석을 실행하고 이를 토대로 연구가설을 설립한 후 이를 검증하기 위한 실증분석을 실시하는 것이다. SPSS를 이용하여 상관분석, 신뢰성과 타당성 분석을 실행하였고, 가설검정을 위한 최종 추리통계분석인 구조 방정식 모델링을 통한 경로분석은 AMOS 통계프로그램을 활용하였다. 분석결과, 경영성과 변수들인 매출, 이윤과 경영만족도에 영향을 미치는 경쟁우위요인들은 다양하게 나타났으며 공통적으로 영향을 미치는 요인은 마케팅인 것으로 확인되었다.

A new manufacturing method using laser transfer technology was developed for a color filter of TFT-LCD. This method can make red, green and blue color layer at the same time without several baking processes. Simple process, no residue, good edge profile, and so on are merits of this process. The same performances (such as color characteristics, reliability, hardness and so on) of current color filter were achieved with this process.

In this paper, we propose a new scalable and reliable combat system software in battleship which was developed procedurally in the past. Recently, combat system software is required to change frequently due to addition of new equipment and change of function. To solve those problems, this paper propose how to change combat system software into scalable software using class structure change and design pattern. Simulation results show that our scheme provides better performances and reliability than conventional scheme. Therefore proposed scheme can be efficiently used in Naval combat system.
