  • This study has been performed to present a new automatic tool wear measurement by digital image processing. The purpose of this paper is to develop an automatic tool wear measuring system based on the image processing which can be applied to the quasi-real time measurement of the characteristics of insert tip in turning. Tool wear monitoring is one of the key-problems, for the development of control systems of modern unmanned factory which are not completely solved now. In oredr words at present complete qualitative and quantitative information on tool wear morphology is required, at least on the following aspects : flank wear, its dimensions and distribution on the maximum and mean values on VB pqrqmeter in the various zones of the wearland. crater wear, its main dimensions and values of KT parameters. This research has been performed to this technique made possible by designing a proper lighting system to the worn tool with following features : The flank wear is measured by observing the active cutting part from a proper direction and by lighting the wearland by a diffuser optic system. The crater wear is visualized by lighting the tool by a He-Ne gas laser system developed in this study. By means of this system it is research to evaluate classical parameters of tool wear and to have complete information about tool wear morphology.

  • It is important to find indicators of quality nursing care to establish the excellence of nursing practice and for the development of nursing as a profession. Caring is one of the indicators which can represent professional nursing care. The purpose of this study was to develop a measurement tool of caring that could be used as an instrument for the evaluation of quality of nursing care. The Target population for the developed tool of caring is the adult patient. The mearsurement tool of caring was developed through the following steps. (1) A list of caring behaviors was made using qualitative researches on caring that has been done in Korea. (2) Caring behaviors in nurses were selected using the list of caring behaviors developed from Watson's 10 factors of caring. (3) Items for the measurement tool of caring were developed using the caring behaviors of nurses (4) Content validity of the developed items was evaluated by an expert panel. (5) The mearsurement tool of caring was developed after a pilot study (6) Internal consistency, and construct validity of the developed tool were verified. (7) The mearsurement tool of caring with the items verified for the internal consistency and construct validity was confirmed. As a result of the study, a mearsurement tool of caring, composed of 27 items with 3 factors, was developed. The Reliability coefficient of the tool was. 9578. The tool is a 5 point Likert scale. The factors of the tool and the number of items for each factor are, 1) accessibility and availablility, 15 items ; 2) emotional support and giving information, 8 items ; 3) providing a protective environment, 4 items.

  • A performance evaluation tool makes an important role in order to improve performance of an embedded software which has restricted computing resources. However, existing performance evaluation tools for embedded softwares cannot be used in collaborative development environment because they support only one developer with performance evaluation work under cross development environment. In this paper, we propose a performance evaluation tool for embedded softwares on collaborative development environment. A proposed tool is based on server and client model. It can have flexibility in offering and integrating the result information for the items. Through the suggested tool. developers can intuitively understand and analysis performance evaluation results each other.

  • Purpose: The purpose of this study was to develop a tool for nutritional assessment, so that home care nurses can make early assessment of patients' nutritional status. Method: The study was done in two parts first a tool was developed to assess nutrition, and second the content validity and clinical validity of the categories and indices were verified. Result: The results of this study are summarized in two ways. First, the nutritional assessment tool was classified into 3 areas, physical measurement, nutritional survey and clinical survey, and into 11 categories with 22 indices. Second, when 5 of the 11 categories were positive, nutritional status was considered to be poor. Conclusion: By developing a clinically useful nutritional assessment tool for patients receiving home care, which was developed in this study, the quality of life for these patients will improve and contribution to the development of a more effective clinical home nursing practice will occur.

  • The main purpose of this study was to develop a program outcomes assessment tool using reflection journal. Reflection journal has recently come to gain more attention from school as an alternative assessment tool. Although numerous studies reconfirmed the educational importance and value of reflection journal as an assessment tool, research on the assessment tool of the engineering accreditation, based on education view is scarce. After literature reviews about the case studies on the program outcomes assessment, this study, to analyse the current assessment tools, and then, examined the educational implications of reflection journal as a program outcomes assessment tool. This study suggested the assessment tool using reflection journal for PO6 (teamwork) and PO11 (engineering ethics), one of the most important assessment items in engineering accreditation. In this study, we used the performance criteria, assessment criteria, rubric, and closed the loop to measure the teamwork and engineering ethics. The result of this study is significant in terms of guiding the future evaluation system development for program outcomes.

  • This paper presents development of a pratical tool deflection compensation system in order to reduce the machining error by the tool deflection in the end-milling process. The system is a tool adapter which includes 2-axis force sensor for detecting tool deflection and 2-axis tool tilting device for adjusting tool position through computer interface in on-line process. In experiments, it is revealed that the force sensor applying parallel plate principle and strain gauge is proper to obtain dynamic process signal, and the tilting device using stepping motor and cam drive mechanism is suitable to have necessary action. By the system and control algorithm, it is possible to get precise machining surface profile without excessive machining error and overcut generated due to increased cutting force in more productive machining condition.
