  • Consumer's product selection measures are being shifted from the units' operational performance to overall performance. Low noise, low vibration, and low power consumption rate, etc. which used to be additional quality indices, now become vital performance factors. Especially, noise and vibration characteristics are being considered as equivalent to/or even more critical than operational performance in certain products such as office machines and home entertainment systems, which share the same space with human being's daily life. Therefore, noise reduction and sound quality improvement technology becomes an inevitable design issue for those applications. Qualitative noise characteristics of rotating polygonal disk applied to digital printer systems are presented. Overall sound pressure level change and tonal noise variation with respect to the geometrical properties of polygonal disk, operational speed, and others are briefly discussed based on experimental results.

  • Recently, IT outsouricng has been one of the major concerns of many companies. This paper explores the relationship between information technology outsourcing risk factors and outsourcing performance. It is based upon a three-phase process utilizing IPO (Input-Process-Output) system. The first phase means the outsourcing planning risks t~at arise from overall environment of outsourcing, organizational refuse, and wrong contracts. The second phase implies outsourcing operational risks, which are occurred while out-sourcing perform and consist of organizational acceptances of outsourcing, partnership and hidden costs. The last phase is outsourcing performance based on four perspective of BSC(Blanced Scored Card). The survey was performed on the IT/IS firms, and the data was collected from 53 service receivers. The result of the analysis are as follows. First, Outsourcing planning risks positively affects the operational risks. Second, Outsourcing operational risks negatively affects the Outsourcing Performance.

  • The development of operational performance indicators is of utmost importance for nuclear power plants, since they measure, track, and trend plant operation. Leading indicators are ideal for reducing the likelihood of consequential events. This paper describes the operational data analysis of the information contained in the Corrective Action Program. The methodology considers human error and organizational factors because of their large contribution to consequential events. The results include a tool developed from the data to be used for the identification, prediction, and reduction of the likelihood of significant consequential events. This tool is based on the resilience curve that was built from the plant's operational data. The stress is described by the number of unresolved condition reports. The strain is represented by the number of preventive maintenance tasks and other periodic work activities (i.e., baseline activities), as well as, closing open corrective actions assigned to different departments to resolve the condition reports (i.e., corrective action workload). Beyond the identified resilience threshold, the stress exceeds the station's ability to operate successfully and there is an increased likelihood that a consequential event will occur. A performance indicator is proposed to reduce the likelihood of consequential events at nuclear power plants.

  • 본 연구는 한국의 대규모 기업집단 형태인 재벌 구조를 중심으로 그룹 내의 기업들 사이에서 운영관리 성과의 전이가 발생하는지를 실증적으로 분석하는 것을 목표로 한다. 공급사슬 관점에서 재벌 그룹은 수평·수직적으로 통합되어 그룹 내 기업들끼리 긴밀한 협력이 가능한 구조로 고려할 수 있는데, 기존 문헌들에서도 재벌 그룹 내 기업들 간 유형·무형의 자원들이 공유되고 있음을 언급하고 있다. 이러한 관점에 기인하여, 본 연구에서는 자원의 협력적 활용이라는 측면에서 재벌 그룹 내 기업들간의 운영관리 성과가 전이될 수 있음을 살펴보고자 하였다. 이를 위해 한국의 공정거래위원회에서 정의한 대규모 기업집단, 즉 재벌에 대한 정보를 수집한 뒤 그룹 내 기업들에 대한 자료를 수집하였다. 이후 매출액을 기준으로 그룹 내에서 가장 매출액이 큰 기업을 선도 기업, 그리고 그 외의 기업들을 소속 기업으로 정의한 뒤 선도 기업의 재고 및 설비 관리의 성과와 소속 기업의 재고 및 설비 관리의 성과간에는 유의미한 양의 연관성이 있음을 알 수 있었다. 이를 통해 본 연구는 경영학적으로 재벌 그룹 내에서 운영관리 성과가 전이된다는 것을 실증적으로 확인하였으며, 본 연구의 결과를 바탕으로 기업들에게 그룹 내 기업들간의 협력체계를 강화해야 한다는 것을 실질적으로 제언할 수 있다. 또한, 운영관리 관점에서 재벌 그룹을 규명하고 운영관리 성과의 전이효과를 실증적으로 제시했다는 점에서 학문적인 시사점을 제안할 수 있을 것으로 기대한다.

  • Customer firms exercise various sources of power to influence their suppliers' behaviors or decisions. In this study we aim to examine the effects of customers' sources of power on their supplier's performance improvement. This study posits that a customer's expert, referent, and reward power positively influence a supplier's performance directly as well as indirectly through increased supplier-customer integration. On the contrary, the customer's coercive power is expected to worsen the supplier's operational performance because of increasing distrust, dissatisfaction, and conflict with the customer. Data collected from 1,229 firms from Korea, China, Hong Kong, Taiwan, and the U.S. are used to test the hypotheses. Expert power proves to be the most effective source of customer power in improving a supplier's inventory cost, delivery, and flexibility performance. In contrast, coercive power deteriorates significantly all supplier performance variables. Academic and managerial implications are presented and future research directions are also discussed.

  • The purpose of this study is to examine an organizational ICT(Information and Communication Technology) performance by ICT investment and policy consistency of government organizations. As the rapid development of ICT is becoming an essential element of social culture, the ICT operation of bureaucratic government also is becoming important. The central government has invested substantially new ICT for improving the quality of nationwide service and to promote administrative efficiency. However, various departments of government occur frequently duplication investments of ICT, and budget conflicts between organizations caused difficulties in maximizing ICT competency. I will confirm the ICT operational performance by ICT investment behavior and organizational work competency as well as the significance of ICT policy consistency. The method of study used a structural equation. The research model set ICT investment behavior as independent variables, organizational work competencies and policy consistency as mediations, and operational performance as dependencies. As a result of the research, New ICT interests show negative effects that caused work change between government organizations and government-funded body. But, New ICT convergence shows positive effects on increasing the two competency variables. The two competency variables show negative effects that caused changes in ICT policy consistency and show no impact on the ICT operational performance. The ICT policy consistency shows a positive effect on enhancing ICT operational performance. The study contribution explain updated the contingency theory and because the ICT policy consistency is essential, negotiation between government organizations will be important. Future research will require a qualitative study through interviews in government organizations about consistency enhance of ICT policy.
