U.S. nuclear regulatory commission(NRC) regulatory guide(RG) 1.20 requires a comprehensive vibration assessment program(CVAP) for use in verifying the structural integrity of reactor vessel internals(RVI) for flow-induced vibrations prior to commercial operation. The CVAP program consist of vibration and fatigue analysis, a vibration measurement program, an inspection program, and a correlation of their results. One of the main purposes of the analysis program is to select measurement locations, however measurement locations can not be determined by only analysis results, therefore we developed selection criteria of measurement locations for advanced power reactor 1400(APR1400) RVI CVAP, It will be used to select measurement locations and instrument types for APR1400 RVI CVAP.

In this paper, we have developed a system for monitoring and processing the real time sensor data in remote site through Internet. For realizing this system, measurement equipment and protocol are used to transmit the measurement data to remote server and to process measurement data. In server part, the received data from remote site sensor is converted to text or graphic charts for user. The measurement device in sensor part receives the sensor data form sensor and store the received data to its internal memory for transmitting data to server part through Internet. Also the measurement device can receive data form server. The temperature sensor is corrected to the measurement device located in laboratory and the measurement device measures temperature of laboratory which can be confirmed by user through Internet. We have developed a server program working on the Linux to store measurement data from measurement device to server memory. The program is use for SNMP(Simple Network Management Protocol) to exchange data with measurement device. Also the program changes the measurement data into text and graphic charts for user display. The program is use apache PHP program for user display and inquiry. The real time temperature measurement system can be applly for many parts of industry and living.

Purpose: This study was done to develop a measurement tool for evaluation of continuing nursing education programs and to verify its validity for effective management and quality of education programs. Methods: The draft of the evaluation measurement was developed from consultation with professionals, focus group interviews targeting groups of nurses, and individual interviews with education program planners. After 6 professionals examined content validity, 46 items were retained. A pilotsurvey was conducted to confirm the time required to complete the questionnaire and the level of understanding of general content and each item in the questionnaire. Construct validity was verified through exploratory factor analysis of data from a survey with 44 items completed by 452 nurses and 59 education program planners. Results: The final evaluation measurement for continuing nursing education programs consisted of 6 evaluation factors and 36 evaluation items. The 6 evaluation factors included identifying program goals and target groups, program planning, performance, operation and management, program outcomes, and program effectiveness. Conclusion: The evaluation measurement for continuing nursing education programs developed in this study is considered suitable to utilize as an evaluation measurement of the quality of continuing education programs for nurses.

Purpose: The purpose of this study is to develop a statistical program for capability analysis of measuring system and measurement process based upon KS Q ISO 22514-7. Methods: R is a powerful open source functional programming language that provides high level graphics and interfaces to other languages. Therefore, in this study, we will develop the statistical program using R language. Results: The R program developed in this study consists of the following five modules. ① Measuring system capability analysis with Type 1 study data: MSCA_Type1.R ② Measuring system capability analysis with Linearity study(Type 4 study) data: MSCA_Type4.R ③ Measurement process capability analysis with Type 1 study & Gage R&R study data: MPCA_T1GRR.R ④ Measurement process capability analysis with Type 4 study & Gage R&R study data: MPCA_T4GRR.R ⑤ Attribute measurement processes capability analysis : AttributeMP.R Conclusion: KS Q ISO 22514-7 evaluates measuring systems and measurement processes on the basis of the measurement uncertainty that was determined according to the GUM(KS Q ISO/IEC Guide 98-3). KS Q ISO 22514-7 offers precise procedures, however, computations are more intensive. The R program of this study will help to evaluate the measurement process.

This paper proposes a method to develop a high-precision dimension measurement system using a linear variable differential transformer sensor. The Dimension targets for measurement is carbon material vanes of key element in the rotating parts within vehicle circulating pump. Data acquisition system for dimension measurement is designed using the NI Compact RIO. And the program applying the dimension measurement algorithm is built using NI LabVIEW. The dimension measuring program is composed of a FPGA program, Real Time program and Host program. The method of the experiment compares master vane with target vane for measure the length of the carbon material vane. The experimental results confirmed the usefulness of the accuracy within ${\pm}4um$.

In the past it was generally felt that software quality was the same as product quality. But as the software industry is getting bigger and more complex, it has become hard to develop quality software that meets customers' needs just depending on product quality. Therefore, lately many domestic and foreign companies are making efforts to upgrade product quality by implementing Process Improvement. Measurement in Process Improvement activities enhances the effect of Process Improvement, and also identifies and helps the activities. In support of this paper, research on the measurement program was conducted based on the CMMI adopted by many domestic and foreign companies for their process improvement model. MA process area that deals with measurement process setup is one of the CMMI process areas and was the basis of the structure of the measurement program. This study presents differences of the measurement program for each level of CMMI and how to apply it. The results of this study can help a business to apply CMMI-based Process Improvement by backing up the structure of the measurement program. Furthermore, it can offer a roadmap for progress of the measurement program for each level.

This study investigated how elementary students' science-related affective characteristics and their perception of measurement changed following participation in citizen science activities through a GLOBE program. Before and after the activities, test of positive experiences about science (PES) and perception of measurement were conducted with twelve fourth grade students. In addition, the teacher who participated in the GLOBE program with students observed and recorded the students' involvement, conversation and behavior to qualitatively analyze the value of the program and the students' perceptions of measurement. After the end of the program, an open questionnaire was conducted to fill any gaps in these observations. The results showed that citizen science activities had a positive impact on elementary students' science-related affective characteristics. In all areas of PES test, the post-test scores were higher than the pre-test results, and a statistically significant difference was seen in the 'science learning motivation' area. Furthermore, students' perception of the value and meaning of measurements was seen to deepen through ongoing global environmental data measurement activities. And their understanding of various units of measurement and numerous situations in which they might need to make measurements was also elaborated.
