The purpose of this study is to examine the current status of Quick Response adoption, and to recognize the implementation problems of QR system in the Korean fashion industry. We reviewed the theoretical background of QR system, analyzed the current status of QR adoption, and identified critical issues to implement the system in our fashion business environment. Previous literatures and information gained from communication service organizations were used for this study The major problems recognized are lack of inter-organizational information network, closed supply channels, non-standardization of QR implementation, and low level of information technology usage including KAN, POS, and EDI. Strong mutual partnership between streams for shared common goals and clear QR mind setting of top management with commitment to information sharing are considered needed for the successful adoption of QR system in domestic fashion industry.

Factory monitoring systems are gaining importance in wide areas of industry. Especially, there have been many efforts in implementation of vibration measurement and analysis for monitoring the status of rotating machines. In this paper, a digital signal processor (DSP) based monitoring system dedicated to the vibration monitoring and analysis on rotating machines is discussed. Vibration signals are acquired and processed for the continuous monitoring of the machine status. Time domain signals and fast Fourier transform (FFT) are used for vibration analysis. All of the signal processing procedures are done in the DSP to reduce the production and maintenance cost. The developed system could also provide remote and mobile monitoring capabilities to operator via internet connection. This paper describes the overview of the functional blocks of the implemented system. Test results based on signals from small-size single phase motors are discussed for monitoring and defect diagnosis of the machine status.

Ppuri or Root technology primarily includes technologies such as casting, mold, plastic working, welding, heat treatment and surface treatment. It is regarded as an essential element for improving the competitiveness of the quality of final products. This study investigates the current status of smart factory implementation for Ppuri companies and analyzes the influencing relationships among various company factors. The factors affecting smart factory implementation for Ppuri companies are sales, exports, number of technical employees, and holding corporate research institutes. In addition, this research shows that even if smart factory implementation is pursued for data collection, data utilization is not implemented properly. Thus, it is suggested that the implementation of smart factories requires not only the availability of facilities and systems but also proper data utilization.

Total Quality Management(TQM) in Higher Education Institution(HEI) has been popular since early 1980s. Implementation of TQM, however, has not been easy. The difficulties of the implementation is partially due to the lack of effective TQM models in HEIs. This paper proposed a new model based on PDCA cycle. The paper consists of four chapters. First chapter Introduces the status of TQM in HEIs and implementation problems. Second chapter delineates the models used in HEIs. In third chapter, a new model is suggested. Last chapter is the conclusions.

WCDMA 시스템에서 radio link간에 data를 주고 받고 신뢰성 있는 data를 검증하는 layer가 RLC이다. RLC에서는 전송 측에서 전송한 data가 수신 측에 잘 전송이 되었는지 status report를 확인을 받고 전송이 이루어지지 않았을 경우 재전송을 한다. 재전송 메커니즘에는 poll 및 status 관련 timer가 존재하면 이러한 파라미터값을 적절히 사용하지 않으면 불필요한 data의 재전송으로 인한 radio resource 낭비 및 시스템 throughput에 영향을 준다.
