  • This study is to evaluate the tool performance in honing using diamond reamer and present grounds whether the localized products are sufficiently competitive comparing with the existing imported ones. The heads of the tool performance evaluation are roundness, roughness, tool life of the workpiece and so on. When evaluating the tool performance, cutting process is divided by three areas which are rough semi-finish and finish cut. cloning improves the accuracy such as boring and reaming after manufacturing the inside diameter, and finishing directly by honing is a recent trend. This honing is used greatly In hard cutting materials like cemented carbides and it is the CBN and diamond that is used in hard cutting materials. Both of them are expensive and most oi them are imported.

  • Recently, traceability systems are introduced as a new food safety information system. To trace food products efficiently, they must have an automatic identification capability at the individual product level. This capability can be gained through RFID technology. But there is not yet any performance evaluation tool on RFID-based traceability systems (RFID-TS). This study developed an evaluation tool of RFID-TS. To develop the tool, this study considered the objective and the components of RFID-TS as their performance constructs. According to Churchill's paradigm, the tool was established through two stages. The final evaluation tool consisted of four constructs (risk, operational benefits, IS (information system), and network) and nine sub-constructs. Among the four constructs, risk and IS were found as the most important performance constructs through regression analysis. Among the nine sub-constructs, service (which belonged to the IS construct) and economic risk (which belonged to the risk construct) were found as the most important performance sub-constructs.

  • 본 논문에서는 그리드 시스템의 스케줄링 알고리즘을 시뮬레이션 할 수 있는 웹 기반의 스케줄링 툴킷(GridTool2)를 소개한다. 그리고 기존 MinMin과 Suffrage 스케줄링 알고리즘에 통신비용을 적용하여 성능이 향상된 수정 알고리즘을 제안한다. GridTool2는 서버와 데이터베이스를 기반으로 웹 환경에서 동작하므로 별도의 컴파일이나 실행 환경을 구축하지 않아도 된다. GridTool2는 통신비용과 함께 성능분석을 위한 변수들을 웹에서 입력하며, 시뮬레이션 결과를 웹페이지에 나타낸다. 통신비용을 적용한 수정된 알고리즘의 향상된 성능을 확인하기 위하여 GridTool2를 사용하여 실험하였다. 실험 결과에 따르면 기존 알고리즘보다 통신비용을 고려한 수정 알고리즘의 성능이 향상되었으며, 특히 작업량이 많아지면 성능향상의 폭이 증가하는 것으로 확인되었다.
