In order to make unmanned machining systems with satisfactory performances, it is necessary to incorporate appropriate condition monitoring systems in the machining workstations to provide the required intelligence of the expert. This paper deals with condition monitoring for tool wear and breakage during turning operation. Developing economic sensing and identification methods for turning processes, sound pressure measurement and digital signal processing technique are proposed. The validity of the proposed system is confirmed through the large number of cutting tests.

As the requirement of user for robot functionality, the function and interface for controlling the robot system is more sophisticated and complicated. Accordingly development process of robot is more complicated and it takes much longer time to develop a robot system. Software development using project management tool is more important in software engineering because of the complexity of software, especially robot system. This paper proposes SEED (Software Engineering Equipment for Development), which is a web-based and integrated software engineering tool to provide independent tools for robot software development. SEED includes the document management tool, the software configuration management tool, the software testing tool on developing robot software and provide a functionality of collaborated and remote development due to WEB-based operations.

A tool holder system has been designed to measure cutting forces in diamond turning. This system includes a 3-component piezo-electric tranducer. In this research, tool holder system is modeled by considering the element dividing, material properties, and boundary conditions using MSC/PATRAN. Mode and frequency analysis of structure is simulated by MSC/NASTRAN, for the purpose of developing the effective design. In addition, tool holder system is verified by vibration test using accelerometer. This system will aid to the development of Fast Tool Servo.

This paper describes the development tool for applications of automotive electronic control unit based on OSEK/VDX. This development tool has a plug-in structure and is written in Java language, because of being based on Eclipse CDT. And also this development tool has another functionality of expansion, which means a special function block can be easily adopted in this development tool. Currently, this development tool consists of five blocks, which are integrated development environment block, fusing program block, system generation block, debugger block, and cross-compiler toolchain block. They have relationship between each other and work for developing OSEK/VDX-based applications. In this paper, we show the functionality of each block of this development tool and its implementation.

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.

새로운 하드웨어 및 운영 체제의 지속적인 출현으로 인해 멀티 플랫폼에서 이식이 가능한 포터블 프로그래밍에 대한 중요성이 더욱 부각되고 있다. 또한 최근 컴퓨터 및 컴퓨터 통신의 발달로 인해 서로 다른 플랫폼으로의 접근 기회가 증가함에 따라 소프트웨어 개발자는 초기 제작 단계부터 여러 가지 플랫폼을 염두에 두고 개발해야 하는 등 소프트웨어 개발 부담이 가중되고 있다. 기존의 GNU 시스템 도구 등에서는 소스 코드의 일부 configuration을 자동으로 생성하게 하고 새로운 플랫폼을 향한 지침서 등을 제시하고 있지만 소프트웨어에 이식성을 부여하기 위한 실질적인 코드는 소스 레벨에서 개발사에 의해 직접 입력되어야 하는 한계가 있다. 본 논문에서는 멀티 플랫폼 소프트웨어 개발을 위한 대화형 의 설계와 구현에 관하여 기술한다. 이 도구는 다양한 유닉스 계열 시스템에 관한 숙련된 지식이 없는 개발자들도 손쉽게 멀티 플랫폼 소프트웨어를 개발할 수 있도록 도울 수 있게 설계되었다. 또한 이 도구는 기존 GNU의 autoconf, autoheader, automake와 같은 시스템 툴을 사용하며, 개발자와 상호작용에 따라 적합한 장소에 포터블 삽입할 수 있다.

Recently the applications of high speed machining are increasing due to the need for high performance and high accuracy machining and machining for difficult-to-cut material. However, the high speed machining also accompanies some problems: the product quality can be degraded due to the tool wear and the product cast can go up due to frequent tool replacements. Therefore, it is necessary to develop a technique of quantitative tool wear measurement to determine the precise timing for tool replacement. In this respect, this study suggests a reliable technique far the reduction of error components by developing a system using a CCD camera and an exclusive jig to be able to precisely measure the size of tool wear in flat end mill for high speed machining.

Purpose: The purpose of this study was to develop a tool to evaluate the nursing competency of ambulatory nurses and to verify the reliability and validity of the developed tool for use in general hospitals. Methods: The evaluation tool for ambulatory nursing competency was developed through a literature review and tests for validity and reliability. Results: Subsequent to a review of the literature on nursing performance of ambulatory nurses, a 12 item questionnaire was developed. Through factor analysis, 12 items in a 2 factor solution were derived. Cronbach's ${\alpha}$ coefficient of the final instrument was .86. Conclusion: The assessment tool developed in this study allows for objective assessments of nursing competencies in relation to the competencies expected of ambulatory care nurses. It is hoped that the assessment tool can be used for empirical verification and to provide basic data for establishing the necessary policies to secure outstanding human resources.
