  • Recently mechanical watt-hour meters are being replaced by electronic watt-hour meters. The replacement period of mechanical watt-hour meters is 7 years. This period is based on long term historical data. The replacement period of electronic watt-meters is also 7 years. This period is determined using the replacement period of mechanical watt-hour meters. However lifetime of mechanical watt-hour meters is different from the lifetime of electronic meters. In order to determine desirable replacement period of electronic watt-hour meters, accelerated life tests of major components in electronic watt-hour meters were performed. The test results showed that LCD was the component which had the shortest lifetime. In this paper, lifetime of electronic watt-hour meters manufactured by 3 company was estimated and life test standard for LCD was developed.

  • This study analyzed the energy demand, greenhouse gas emission and greenhouse gas reduction potential of Electronic Electrical components company. The LEAP model targeting long term energy plan was used to establish the most efficient plan for the companies by examining the climate change policy of government and the countermeasures by companies. A scenario was created by having 11 greenhouse gases reduction plans to be introduced from 2011 as the basic plan. Regarding input data, energy consumption by business place and by use, number of employee from 2009 to 2012, land area and change in number of business places were utilized. The study result suggested that approximately 13,800 TJ of energy will be spent in 2020, which is more than 2 times of 2012 energy consumption. When the integrated scenario based on the reduction plan of companies would be enforced, approximately 3,000 TJ will be reduced in 2020. The emission of greenhouse gases until 2020 was forecasted as approximately 760,000 ton $CO_2eq$. When the integrated scenario would be enforced, the emission will be approximately 610,000 ton $CO_2eq$, which is decrease by approximately 150,000 ton $CO_2eq$. This study will help the efficient responding of eElectronic Electrical components company in preparing detail report on objective management system and enforcement plan. It will also contribute in their image as environment-friendly companies by properly responding to the regulation reinforcement of government and greenhouse gases emission target based on environment policy.

  • Electronic throttle control(ETC) is critical to drive ability, fuel economy and emission performance of present day passenger vehicles. Until now, many automobile engineer and company have been development electronic throttle controller and control algorism, such as adaptive control, sliding control, nonlinear and so on. But there are almost electronic throttle control using DC motor or stepping motor. This paper is the design of an electronic throttle controller and electronic throttle valve control using BLDC motor instead of DC motor.

  • In this paper an attempt is made to understand contribution factors in the field of electronic commerce(EC). To do that, we adopt and modify an existing commerce model. The following two major conclusions are drawn from our simulation. Most of all, the diminution of information delay introduce monotonous growth rather than fluctuation of EC market. The stable increase of revenue or market scale makes us decide the employment or capacity scale quickly. Second, for favorable and continuous evolution of EC, utilization system of electronic money should be established steadily. The following findings strongly support our claim: We found full oscillation of EC market when electronic money system didn't established well. On the contrary, if electronic money system could provide fast cash flow and fully trustful function, decisions of company or consumer would be executed promptly.

  • 최근 $20{\sim}30$년 동안 정보통신기술의 급속한 발전과 이를 활용한 전자상거래의 빠른 확산은 국제상거래인 무역 역시 전자적인 방식으로 거래가 가능하게 하였다. 이로 인해 추후 국제간 거래에 있어 전통적인 대규모 거래방식이 아닌 전자무역사이트를 이용한 소량 다빈도 거래가 빈번하게 이루어질 전망이다. 이에 본 연구는 위에서 언급한 무역거래 패러다임의 변화에 대응하고 이를 활성화하는데 반드시 필요한 국내 제3자물류 산업의 발전방안을 제시하고자 하였다. 기존의 연구에서는 국제 제3자물류산업의 그 자체에 대한 발전방향만을 제시하고 있으나, 본 논문에서는 전자무역과 연계한 국제 3자물류산업의 발전방향에 대해 연구하고자 하였다. 이를 위해 본 연구에서는 먼저 전자무역과 제3자물류에 대한 개념과 관련성을 제시하고, 이를 바탕으로 국내 제3자물류의 문제점을 제시하고 이에 대한 발전방안을 제시하였다. 전자무역과 관련하여 국내 제3자 물류의 문제점은 경영자의 인식부족, 물류비의 비중과다, 마케팅차원의 고려 부족, 전자상거래와 연계한 통합물류서비스 시스템의 미비, 전문인력 부족, 중소기업 상호간 물류공동망의 부족, 전문물류회사의 영세성, 물류관련 법규의 복잡, 물류기업간 담합 등으로 나타났다. 국내 제3자물류의 발전방안은 정부차원에서 법 제도의 정비, 통합물류정보시스템을 구축하기 위한 재정적 기술적 인프라 확대 지원, 보안 및 인증시스템 구축, 물류거래알선사이트의 활성화, 세제지원, 전문인력 양성 체계 확립 등이 있다. 기업차원의 물류발전방안으로는 혁신적 물류시스템과 연계한 통합물류정보시스템의 구축, 전자거래사이트에 연계한 원스톱 물류서비스 제공, 선진 3자물류 기술적 노하우 축적, 문전운송체계 실현, 전반적 거래진단 시스템 구비, 전략적 제휴를 통한 국제경쟁력 강화 등이 필요한 것으로 나타났다. 본 연구의 목적은 이상과 같이 국제 제3자물류의 발전방안을 제시함으로써, 미래 국제무역의 새로운 패러다임인 소량다빈도 형태의 전자무역 활성화에 기여하는데 있다.

  • Product catalog information is the most important factor to make customers purchase the product for various B2B or B2C businesses provided on the Internet. As catalog information differs from company by company, it cannot provide common criteria standard to customers to make decisions. Therefore, it is necessary to develop a platform independent system, which integrates incompatible data from each company' catalogs and manages its database. This paper describes the integrated E-catalog system made up DB module, catalog management module, and interface module. This system allows customers to view standardized product catalog information from different companies with real -time updates, and also provides extensibility, flexibility, and interoperability for the effective E-Business management.

  • Developing a new commercial product, it is need to connect the end users demand of quality to the industrial technology of company. For this reason, this study is to build up the users demand for the imminent marketing product of a certain company by Analytic Hierarchy Process, analyze quantitatively users subjective thoughts collected by Group Consensus, calculate the added-value of users demands and verify the consistency of users opinions by consistency-exponential-calculation. The added value obtained by this method is substituted into a user-demand item of Quality Function Deployment. And, the technical characteristic data transferred from the extracted essential factor for developing and manufacturing a new product is substituted into a technical characteristic item of QFD. The faculty of quality is firstly finished by this procedure. But, because the relation a technical characterization with users demand do not be known in new product, Wassermans method was introduced for the correlation users demand with technology and for the processing and marketing of a new product. The all assumption on this thesis was based on the reliable real data of a certain company.

  • This paper considers a web-based order processing system under SCM environment. Following the framework of B2B electronic commerce, we focus on activities closely related to order handling within the supply chain. We also try to integrate the order processing system with the overall information system of the company. The methodology is applied to the case of H company and a prototype system is designed. This study analyzes the current product estimate and order handling process in the point of view of both the purchasing and the selling companies. It intends improvement by changing the existing closed way of request and offering estimate through fax or VAN into an open way using internet. For this, a company should be registered on the order site of internet. Then it can request estimate, take estimate, and handle order through internet adopting the concept of electrical commercial transaction.

  • The purpose of this study is to empirically analyze the productivity change of the 10 Single PPM Certification Company in the 3 Industry(Electronics, Motor-Parts, Machines). In this study, Productivity change over the time in Korean small and medium sized firms in the 3 industries by the bootstrapped Malmquist Productivity Index(MPI). The traditional Malmquist Productivity Index(MPI) and Data Envelopment they could lead to wrong evaluations of the efficiency and productivity scores. In this paper, DEA and a MPI are combined with a bootstrap method in order to provide statistical inferences that analyze the performance of the Single PPM Certification Company. The data cover the period between 2004 and 2007. The result of this paper reveals : 1) The electronic industries(Motor-Parts, Machines). 2) average productivity Progress of the 7DMU(Electronics), 1DMU(Motor-Parts) and none(Machines).
