The purposes of this study are to develop a measuring instrument for the analysis of science classroom culture from the perspective of Community of Practice (CoP) and to confirm its feasibility. We set the structural factors of CoP and developed preliminary questions through literature review. The validity and reliability of the instrument were examined and modified through the pilot survey participated by a total of 219, 4th, 6th, and 8th grade students. The modified instrument consisted of 5 factors of 'responsibility for learning', 'common interest', 'mutual relationships', 'open participation', and 'practice', comprising a total of 27 items. As the main survey, confirmatory factor analysis and reliability analysis of the instrument were carried out with a total 706 students of the 4th and 6th grade. This measuring instrument was validated and used for analyzing the culture of science classroom CoP of elementary school by comparing the data from the main survey in terms of structural factors, grade, gender, and teacher type. The measuring instrument is expected to be used not only for analyzing science classroom culture from the perspective of CoP, but also for offering implications for the desirable science classroom culture.

Purpose: This study was done to develop an instrument for measuring intellectual capital and assess its validity and reliability in identifying the components, human capital, structure capital and customer capital of intellectual capital in hospital nursing organizations. Methods: The participants were 950 regular clinical nurses who had worked for over 13 months in 7 medical hospitals including 4 national university hospitals and 3 private university hospitals. The data were collected through a questionnaire survey done from July 2 to August 25, 2009. Data from 906 nurses were used for the final analysis. Data were analyzed using descriptive statistics, Cronbach's alpha coefficients, item analysis, factor analysis (principal component analysis, Varimax rotation) with the SPSS $PC^+$ 17.0 for Windows program. Results: Developing the instrument for measuring intellectual capital in hospital nursing organizations involved a literature review, development of preliminary items, and verification of validity and reliability. The final instrument was in a self-report form on a 5-point Likert scale. There were 29 items on human capital (5 domains), 21 items on customer capital (4 domains), 26 items on structure capital (4 domains). Conclusion: The results of this study may be useful to assess the levels of intellectual capital of hospital nursing organizations.

Purpose: Even though a number of studies have suggested that appropriate measuring instruments of family stress for working women have to be developed, the validity and reliability of the instruments used have not been consistently examined. The purpose of the present study was to develop a sensitive instrument to measure family stress for married working women, and to test the validity and reliability of the instrument. Method: The items generated for this instrument were drawn from a comprehensive literature review Twenty four items were developed through evaluation by 10 experts and twenty one items were finally confirmed through item analysis. Psychometric testing was preformed and confirmed with a convenient sample of 240 women employed in the industrial sector. Result: Four factors evolved by factor analysis, which explained 50.5% of the total variance. The first factor 'Cooperation' explained 28.1%, 2nd factor 'Satisfaction with relationships' 10.6%, 3rd factor 'Democratic and comfortable environment' 6.3%, and 4th factor 'Disturbance of own living' 5.5%, Cronbach's coefficient of this instrument was 0.86. Conclusion: The study supports the validity and reliability of the instrument.

Manufacturing accuracy of a precision instrument was essential to stability and efficiency of the product. Accordingly, geometrically accuracy management of precision instrument was very becoming the technique in order to design and manufacturing for machine. In this study, Measuring System is developed for extra long roller using non-contact sensor. Futhermore, It's studied by Geometric Tolerance. Exact roundness is obtained to Least Squares method from the reference circle of measured data. Measuring System is analyzed point of measurement and straightness of extra long roller is evaluated by FEM.

Portable sheet resistance-measuring instrument using the dual-configuration Four-Point Probe method is developed for the purpose of precisely measuring the sheet resistance of conducting thin films. While single-configuration Four-Point Probe method has disadvantages of applying sample size, shape and thickness corrections for a probe spacing, the developed instrument has advantages of no such corrections, little edge effects and measuring simply and accurately the sheet resistance between $0.2\Omega/sq$ and $2k\Omega/sq$.

To meet tight tolerance requirements of mass produced shafts which are subcomponents of automobile parts, an automated measuring system has been developed. The system comprises of a non-contact shaft diameter measuring instrument using laser, a feed mechanism of a step motor and ball screw and a personal computer. The system can determine pass-fail of the piece under test and also analyze data for statistical process control.

Among the many factors that threaten the improvement of public health and quality of life, the proportion of fine dust is not so small, and the kinds and causes of the dust are also diversified. However, the domestic measuring instrument is in the initial stage and the certification system is insignificant. Recognizing the threat of fine dust for a long time, the United States has established a protocol of measurement standards and measurement methods and applied the developed fine dust measuring device authentication system. Through this system, the United States is leading the world's fine dust industry, technology and market. The EPA, FRM and FEM of the fine dust-related protocol were analyzed to reduce the harmful effects of repeated fine dust every year. In addition, light scattering method and spectroscopy method which can measure in real time by measuring method were examined, and the types and characteristics of fine dust measuring instrument of international certification level were analyzed. Finally, development and service plan of the domestic fine dust measuring instrument are presented.

There is a need to enlarge the mother glass substrate in OLED to raise its productivity and to realize OLED TV. On the other hand, some difficulties may arise regarding the deflection of a large glass substrate during its handling operation due to its thinness $(0.5\sim0.7t)$, which is not even enough to allow it to stand its own mass. This thesis proposes a conceptual plan for the application of the clamping- and bending-end conditions to the glass substrate handler. To verify proposed plan, the non-contact 3 dimensional measuring instrument is developed. The composition of the 3 dimensional measuring instrument measures shape of the product using X-Y stage robot and laser distance sensor. X-Y stage robot and laser distance sensor are controlled by LabVIEW language. To calibrate measuring instrument, the direction conversion of the Euler angle was used. In order to confirm deflection of the glass substrate, the experiment was carried out at the bending end boundary condition and the proposed effect was verified.

Purpose: This study aimed to develop a survey instrument to assess the Patient Safety Culture in Korean hospitals and evaluate its validity and reliability. Methods: A preliminary instrument was developed through a literature review, focus group interviews, content validity testing, and pretesting for face validity. A total of 467 hospital employees participated in the psychometric testing. Validity and reliability assessments included content validity, construct validity, criterion-related validity, and internal consistency. Results: The Korean Patient Safety Culture Survey Instrument comprised 35 items across seven factors: leadership, patient safety policy and procedure, patient safety improvement system, teamwork, non-punitive environment, patient safety knowledge and attitudes, and patient safety priority. These seven factors contributed 60.98% of the variance of the total scale. Cronbach's alpha for internal consistency was .93; the seven factors ranged from .66 to .91. Conclusion: The results of this study showed that the Korean Patient Safety Culture Survey Instrument is reliable, valid, and suitable for measuring patient safety culture in Korean hospitals.
