Background: Regional Cardiocerebrovascular Centers (RCC) were established for the prevention and treatment of cardiocerebrovascular disease and funded by the Ministry of Health and Welfare. The purpose of this study was to develop and validate the measurement tool of public benefits in RCC. Methods: Through the intensive literature review, experts surveys and their repetitive feedback, we selected the 46 items about the public benefits in RCC. Development of measurement tool involved content validity test using Content Validity Index (CVI), construct validity test through factor analysis and reliability test. Results: Thirty-five items were selected by content validity test, which CVI was 0.08 or higher. Through the construct validity test, 32 items in 7 factors were derived. And Cronbach's alpha was 0.951. Finally, public benefits measurement tool is composed of 32 items in 7 factors which are comprehensiveness of health care services, market complement, emergency care, cost, governance, quality improvement, and government control. Conclusion: Though we developed the measurement tool of public benefits in RCC, it would be utilized to measure the public benefits of various health agencies.

This paper deals with condition monitoring for tool wear during tuning operation. To develop economic sensing and identification methods for turning processes, sound pressure measurement and digital signal processing technique are proposed. To identify noise sources of tool wear and reject background noise, noise rejection methodology is proposed. features to represent condition of tool wear are obtained through analysis using adaptive filter and FFT in time and frequency domain. By using fuzzy pattern recognition, we extract features, which are sensitive to condition of tool wear, from several features and make a decision on tool wear. The validity of the proposed system is condirmed through the large number of cutting tests in two cutting conditions.

Purpose : This study aimed to develop and validate a reliable tool, the Korean physical therapists' work environment scale (K-PTWES), for assessing the work environment of Korean physical therapists. The study also sought to examine the validity and reliability of the instrument. Methods : This methodological study involved the development and testing of the measurement tool. The conceptual framework was established through a literature review and in-depth interviews with clinical physical therapists. A total of 40 meaningful statements emerged from this process, leading to the generation of 29 primary items. Following a content validity test, 29 items were selected for the preliminary tool. Data were collected from 220 physical therapists across various job roles and unit types, such as outpatient and inpatient physical therapy rooms in domestic hospitals, with more than one year of experience. The final analysis included data from all 220 physical therapists. Results : Varimax rotated principal component analysis was employed for validities, revealing four factors: organizational support, working system, sustainable development, and relationship with coworkers, explaining a total variance of 54.97 %. The Cronbach's α coefficient for the final tool was .939, indicating high reliability. Conclusion : In this study, we developed a measurement tool reflecting the characteristics of the Korean physical therapists' work environment scale (K-PTWES). Our findings highlight the tool demonstrated both validity and reliability. Utilizing this tool is expected to contribute to understanding the work environment of Korean physical therapists and fostering a healthy work environment. Based on our findings, we recommend, firstly, conducting research on the work environment and related factors of physical therapists working in diverse settings using the K-PTWES. Secondly, future studies should focus on validating the tool's criterion-related validity, as it was not addressed in this research.

This paper diagnose subjects and measures the learning ability of students based on the goal of developing an assessment tool for education productivity based on multi-aspect evaluation conducted by ICEE at Honam University. Furthermore, develop an assessment tool for education productivity that provides a motive to bring detailed improvements in teaching methods through the diagnosis. In addition, a method for compensating the issues and improving the quality of subject is suggested to develop learning ability of students through applying the assessment tool. An integrated operated system of CQI is desired to be built along with quality improvement of education through measuring academic quality by studying the methods for enhancing academic and learning ability achievement from analysis of the curriculum provided in the "ABEEK program". Through this study the current state of education productivity is presented through analyzing the difference between students who participated in the "ABEEK program" and who did not participate, and operating a comparison between the student's comprehension on their majors and liberal arts by the multi-aspect evaluation that has been conducted for 2 years.

Since the recent Corona 19, the importance of cloud computing is increasing, and at the same time, competition among clouds is intensifying. Cloud companies are competing for survival by promoting various management innovation methods for continuous growth and development amid a rapidly changing business environment. They are also increasingly interested in performance management in their operations and growth. In this paper, we propose Cloud BSC, an IT BSC-based performance measurement model for cloud enterprise performance management. The validity of the proposed model is verified through statistical analysis and causal analysis. Eventually, the proposed model is expected to be utilized as a management evaluation tool that can provide useful performance analysis information to cloud companies.

This paper proposes the development of a new method for online analysis which measured acid concentration in a pickling line. Pickling is the most important step to remove surface scale layers and is strongly depending on the exactly controlled pickling liquor composition. Today, there is no feasible system available for the online control of pickling lines. Within this paper, new methods for online analysis of pickling liquors have been tested and implemented into an overall pickling process control tool. This method measured simultaneously the hydrochloric acid and iron ion concentration in a solution of hydrochloric acid by measuring the ultrasonic speed, the solution temperature, and the electrical conductivity. Experimental results showed excellent precision and the measurement error was ${\pm}2g/l$ compared with the neutralization titration measurement.

Purpose: This study aimed to analyze the research trends on the image of emergency medical technicians (EMTs) in studies published in Korean journals. Methods: Electronic databases were searched, including RISS, KMbase, and KCI. Eight studies from 21 references screened were included in the analysis. Results: The number of studies related to the image of EMTs is severely lacking. The research methods and participants are limited to questionnaire surveys and EMT students, respectively. In addition, most of the studies used modified tools developed for image measurement of other occupations. Conclusion: Image research for EMTs should include various methods and participants. Standardized measurement tool development and image-related research should be steadily conducted.
