  • Efficient development of method on a performance evaluation for machine tools has been regarded as the most important work for accuracy and quality enhancement to every user and manufacturer. A evaluation method of accuracy for machine tools has been studied recently according to the rapid increase of interest in precision machine tools. To this point of view, the circular interpolation test of machine tools is recognized as the most useful method to distinguish a dynamic accuracy of NC machine tools by ISO and ANSI/ASME, etc. In this paper, we have studied and developed the form measurement system with grid encoder to analyse the final accuracy of NC machine tools. we have analyzed the servo system error and geometric error of NC machine tools through measuring a dynamic error signal by this system. and then we verified the experimental result and enhanced the reliability by means of comparing the characteristics of the developed system with the kinematic ball-bar system.

  • The acceleration of the performance of machine tools influences the development of the semi-conductor and optical technology as the development of NC and measurement technology. We can mention that a traction role of the acceleration for the development like that depends on the development of the measurement technics Stylus instrument method, STM, SEM, Laser interferometer method which are used for measuring the quasi-static error of machine tools. Because the measurement has been done to unload condition without considering of mechanical stiffness in the case of machining center as we measure the quasi-static error of machine tools on general studies, people who works on the spot has many problems on the data value. Therefor we will help working more accurately on the spot by measuring, analyzing, displaying the deflection of the table and support shaft when we load on the table and the support shaft of machining center using laser interferometer. Also we try to settle new conception of the measurement method and more accurate grasp of the deflection tendency by verifing the tendency of the error measured through the comparison of the simulated error using ANSYS, a common finite element analysis program, which is able to measure heat deformation, material deformation, and error resulted form this study.

  • It was estimated by an analysis method thai the inner shell of HANARO reactor will be deformed due to pressure, loads, creep and growth during reactor operation. To confirm the analysis validity and safe operation of reactor, we developed tools to remotely measure the straightness of the inner shell located 12m below the pool top. The performance and the accuracy of the measurement tools have been verified through tests using a dummy inner shell and steel straight edge. The accuracy of the measurement shows very good results with a maximum error of 0.06mm by steel straight edge. The technical experiences described in this paper will be a good reference not only for the operation and maintenance of HANARO but also for the next performance of the measurement in the future.

  • An image is a comprehensive result that you have experienced about an object and means the image that you have on the surface of your consciousness. The image of the subject has an important influence on learning the subject. The image analysis of the subjects that the learners have will be good data to decide the direction of teaching and learning. The purpose of this study is to develop and apply measurement tools for physics image and discuss its educational implications. The research method is to develop the measurement tools for the physics image by semantic analysis method and apply it to the secondary pre-service physics teacher. The subjects of the study were 39 first graders, 31 second graders, 37 third graders, and 38 fourth graders at the University of Education, a total of 145 students, 82 of whom were male and 63 were female. The study results show that the image measurement tools for physics consisted of 25 items from five elements: 'interest,' 'feeling,' 'scope,' 'evaluation,' and 'viewpoint.' There were statistically significant differences between the male and female students in applying the measurement tools developed for the physics image of secondary pre-service physics teachers. Male students showed significantly higher statistical significance than female students in the 'interest' and 'feeling' elements of measurement tools for the physics image. In the 'scope' element of measurement tools for the physics image the second grade was statistically higher than the fourth grade. Finally, we discussed educational implications for image analysis of physics and the usefulness of using measurement tools in physics image.

  • This study investigates the overall research trends and related factors affecting the turnover of dental hygienists in Korea during the past 10 years (2007-2017) and analyzed the differences in the results of the research according to the main measurement tools. The literature review focused on turnover of dental hygienists in Korea. Inclusion criteria of selected studies were as follows: the domestic and foreign academic journals and theses published for the past 10 years (between 2007-2017). The most commonly used tool for measuring dental hygienist turnover was a tool developed by Lawler. The most used significant general characteristics is age and income, Job satisfaction (57.1%) and organizational commitment (40.0%) were the most frequently used predictors of turnover. The variables used for each turnover measurement tool were different, showing that the study results was different from according to the variables and significance level. Although there have been many studies related to the turnover of dental hygienists, different results have been shown depending on the measurement tools. When conducting research related to dental hygienist turnover, specific and clear presentation of measurement tool selection or development is needed.

  • To improve the accuracy of products and improve the product quality, we need to enhance the machining accuracy of the machine tools. To this point of view, measurement and inspection of finished part as well as error analysis of machine tools has been studied for last several decades. OMM(On the Machine Measurement) has been issued to alternate with CMM, pointing out disadvantages of high expenses and lots of setting time in CMM. In this paper, we study 1) the spherical surface manufacturing by volumetric error compensation of machine tool, 2) the system development of OMM without detaching work piece from a bed of machine tool after working. 3) the generation of the finished part profile by On the machine measurement. Furthermore, the output of OMM is compared with that of CMM, and verified the feasibility of the measurement system.

  • Objectives : To introduce and compare various headache measurement tools, in order to provide fundamental information for future clinical trials and development of oriental medicine measurement tools. Methods : Eight headache assessment scales, Migraine-Specific Quality of Life Questionnaire(MQoLQ), Migraine-Specific Quality of Life(MSQOL), Migraine-Specific Quality of Life Questionnaire(MSQ), The Headache Impact Questionnaire(HImQ), Headcahe Needs Assessment Survey(HANA), Henry Ford Headache disability Inventory(HDI), Migraine Disablity Assessment Scale(MIDAS) and Headache Impact Test(HIT-6), were searched through Pubmed. General character, the process of development, verification of reliability, internal consistency, responsiveness to patient's change and validity were reviewed. Results : In assessing the quality of life of migraine patients, MQoLQ can be used to measure the change within 24 hours, MSQ and MSQOL can be used to measure the change during a relatively longer period of time. The frequency and bothersomeness of headache can be easily measured by HANA. HImQ can be used to measure the intensity of headache and the influence on normal daily activities. HDI can measure the emotional difficulties of headache patients. HIT-6 and MIDAS makes measurements possible in a short period of time, and the reliability and validity have been verified numerously. HIT-6 and MIDAS are the most frequently used measurement tools because they are simple and easy for both the assessor and the patient to understand and use. Conclusions : In this study, various headache assessment tools have been reviewed. The assessed tools were widely used after being verified for their reliability and validity. We hope this study provides fundamental information in establishing future clinical trial and clinical practice guidelines. We also hope this study to contribute to the development of an oriental medicine assessment tool for headache.
