This research project studies the relationships between each phase of ERP systems implementation and its impact on system performance based on SDLC(System Development Life Cycle). In general, ERP systems life cycle consists of chartering phase, project phase, shakedown phase, and onward and upward phase Interviews with users as well as builders of ERP systems were conducted. Total 859 questionnaires were sent and 106 usable questionnaires were returned. The contributions of this research project are three-fold. First, an integrated model for successful ERP systems implementation were built based on factors influencing ERP systems. Second, this study analyzed the completeness of each phase and its impact on ERP system performance. project phase and onward and upward phase are found to be positively associated with system performance. Finally, this research project also investigated the relationship between completeness of each phase. we found that all the phases of ERP system implementation were influenced by previous phase.

The overall objective of this study is to empirically investigate organizational/managerial factors affecting system development team operation. The contributions of this research project are two-fold. First. this study examined various organizational/managerial factors that made team operation successful. Second. we presented the key success factors among the identified success factors of team operation. A field investigation of 68 system development teams located around YoungNam area indicates that motivation. leadership and egalitarian team culture are success factors of team operation. Especially. key success factors are leadership and egalitarian team culture.

The rate constants for the hydrolysis of chalcone at various pH range were determined by spectrophotometry and a rate equation which can be applied over wide pH range was obtained, The reaction mechanism of hydrolysis of chalcone which has not been studied carefully earlier in the acidic and neutral solution can be fully explained by the rate . equation obtained. The rate equation reveals that, below pH 12.0, the reaction is initiated by the attack of a water molecule on the carbon-carbon double bond, Above pH 13.5, the overall rate is only dependent upon the concentration of hydroxide ion, In the range of pH from 12.0 to 13.5, these two reactions occur competitively.

물품 검사를 위한 산업현장에서는 물품의 표면뿐만 아니라 내부 부품결함 검사 또한 필요하다. 일반적으로 생산 공정에서의 물품 검사로 광학 검사를 많이 이용한다. 하지만 이는 표면상의 결함만을 검사할 뿐 물품 내부의 검사를 수행하기는 어렵다. 이러한 제한점을 극복하기 위해 광학 장치 대신 휴대용 X-선 DR 영상 획득 장치를 이용하여 영상을 실시간으로 얻는 동시에 제품 불량을 판별할 수 있는 시스템을 개발하였다. X-선 영상을 얻은 후 머신영상 처리를 통해 설정한 기준 값에 오차범위를 허용하면 통과, 그렇지 않으면 불량으로 인식되도록 시스템을 개발하였다. 또한, 물품의 불량 유무 결과와 그 수치는 사용자가 저장할 수 있도록 하였다. In the industrial field for product inspection needs not only on the surface of the product but also the internal components defect inspection. Generally, optical inspection is mainly used for item inspection from production process. However, this is only to check defect of surface it is difficult to perform inspection of goods internal. To overcome these limitations, Instead of optical device by using the portable X- ray DR image acquisition device system developed to obtain an image in real time at the same time and determine product defects. After obtaining the X- ray image, the inspection product within error range is passed after machine image processing. Also, the results and numbers are stored by users.
