Purpose: This study aimed to investigate the perspective of consumers in healthcare services regarding patient safety. Methods: The study was a descriptive study using a self-reported questionnaire. The questionnaire was based on the Senior Empowerment and Advocacy in Patient Safety (SEAPS) questionnaire, which was designed to assess patient safety health beliefs. The survey was conducted online and a convenient sample of 302 adults participated in total. The reliability of the measurement (Cronbach's ${\alpha}$) was 0.758 in attitude (ATT), 0.546 in out-come efficacy (OE), 0.757 in self-efficacy (SE), and 0.703 in behaviors (BEH). Results: The average patient safety awareness score of the healthcare service consumers was 2.72 (ATT), 2.91 (OE), 2.87 (SE), and 2.27 (BEH). Our analysis indicated that there were no differences in ATT, BEH, or SE by gender, age, or education level. However, in OE and the total score of the four subscales, there were significant differences by age and gender. Correlations were identified between BEH and SE (r=0.409, p<.01), BEH and OE (r=0.202, p<.01), ATT and SE (r=0.358, p<.01), and OE and SE (r=0.241, p<.01). Conclusion: This study measured consumer perspectives concerning patient safety. The findings demonstrate the need for developing a measurement tool to assess consumer's perception of patient safety, considering Korean healthcare system and cultural context.

Purpose: Studies focus on cancer control, prevention, or assessment of psychosocial problems and intervention methods. However, few studies exist concerning psychosocial problems, measuring tools for those problems, and interventions for cancer patients in Korea. One of the purposes of this study was to review studies in this area, to examine various psychosocial problems experienced by cancer patients. This is a crucial area to investigate, since psychosocial problems in turn negatively influence the patients' immune function, which speeds the progress of the disease. Another goal was to identify instruments used to measure psychosocial functioning and problems in cancer patients, to analyze their validity and reliability, with the aim to discover the best instruments. A final goal was to explore and compare the effects of psychosocial interventions, to determine the most effective practices. Method: Journal articles published since 1995 were searched from PubMed Data base, Google search engine, and published cancer-related studies, using search keywords "psychosocial function and intervention for the cancer patients"; whole articles of selected references were reviewed and analyzed. Result: Most common psychosocial problems were depression, fatigue, nausea, pain, distress, resulting in a low quality of life. The seven scales found in the literature to assess the psychosocial functioning were Center for Epidemiological Studies-Depression, State-Trait Anxiety Inventory, Symptom Checklist 90-R, Profile of Mood States, Psychosocial Adjustment to Illness Scale, Brief Symptom Inventory, and SF-36 HRQOL(Health Related Quality of Life). Social support interventions for cancer patients were effective in improving quality of life scores. Conclusion: It is necessary to apply support intervention strategies to help cancer patients in Korea. These strategies can help to reduce the effects of psychosocial symptoms, which in turn affect the development and control of cancer. Strategies developed in Western countries may need to be modified for use within Korea. Further studies are warranted to review the support intervention strategies that were being used to for cancer patients

With the recent introduction of 5G, electromagnetic radiation sources are spreading throughout life, so it is necessary to establish a citizen-centered electromagnetic safety management system. In particular, the beamforming method of the 5G antenna increases the power density measurement of electromagnetic waves by more than 10 times when the wireless base station is installed, so it is unreasonable to determine the safety by physical measurement. Therefore, it is necessary to determine the presence or absence of electromagnetic wave safety in daily life through a predictive method by calculation through systematic model analysis. In this paper, in order to check the possibility of a 5G wireless base station using an electromagnetic wave numerical analysis tool as a way to solve this problem, we compared the measured values of the actual base stations and the predicted values through the prediction model to compare the reliability. A method of constructing a real-time base station electromagnetic wave strength prediction evaluation system combined with software was also proposed.

With the expansion of Voucher program, academic and practical concerns of performance evaluation of voucher service has been more emphasized. Accordingly, client satisfaction survey are expanding these days, but the study of client satisfaction as a performance indicator aimed at service client has not been yet conducted systematically. The purpose of this study is to develop Satisfaction Index, targeting at client of community-development voucher program in Community Service Investment Project conducted by the Ministry of Health and Welfare. Data were collected from 1800 client of community-development voucher program. This study summarized theoretically many kinds of satisfaction measurement and composed the Satisfaction Index reflecting characteristics of Voucher. By the item analysis and reliability analysis, the element satisfaction was identified as homogeneous items. General satisfaction were obtained using element satisfaction and overall satisfaction, it was found to be valid through the evaluation of convergent and discriminant validity as a tool for satisfaction. This study suggest using the '1step weighted approach' than '2step weighted approach' having weakness of complex overlapping manner.

This study is a methodological research study that tests the validity and reliability of the NCRC (Nurse Clinical Reasoning Competence scale), an instrument developed by Liou and his colleagues as the basic data for enhancing the clinical reasoning competence of nurses, by translating it into Korean and checking the similarity of the sentence structure and meaning (between the two versions?). This study verified its validity and reliability by examining 166 nurses working in four tertiary hospitals located in Seoul and Busan. An analysis of the content validity by experts showed that all of the items have a content validity higher than CVI 0.8. From the exploratory and confirmatory factor analysis, it was found that the instrument includes a total of 15 items consisting of one factor. In addition, the correlation with the Korean version of the Nurse Clinical Reasoning Competence scale is confirmed to test the concurrent validity, by using a measurement tool of nurses' critical thinking dispositions and clinical decision-making abilities (correlation coefficient =.55-.64(p<.001) and Cronbach's ${\alpha}=.93$). Thus, the Korean version of the NCRC may be a useful instrument for evaluating the clinical reasoning competence of Korean nurses and providing the basic data for assessing their clinical reasoning competence and developing their promotion strategies.

This study aimed to verify the validity of a measurement tool for Vietnamese high school students' systems thinking abilities. Two quantitative assessment tools, the Systems Thinking Measuring Instrument (Lee et al., 2013) and the Systems Thinking Scale (Dolansky et al., 2020), were used to measure students' systems thinking after translation into Vietnamese. As a result, it was revealed that Cronbach-α for each tool (i.e., STMI and STS) was .917 and .950, respectively, indicating high reliability for both. To validate the construct validity of the translated questionnaire, exploratory factor analysis was performed using SPSS 26.0, and confirmatory factor analysis was performed using AMOS 21.0. For concurrent validity, correlation analysis using structural equation modeling was performed to validate the translated questionnaire. Exploratory factor analysis revealed that 10 items from the STMI and 12 items from the STS loaded on the intended factors and appropriate factor loading values were obtained. For confirmatory factor analysis, a structural equation model organized with 10 items from the STMI and 12 items from the STS was used. The result of this showed that the convergent validity values of the model were all appropriate, and the model fit indices were analyzed to be χ²/df of 1.892, CFI of .928, TLI of .919, SRMR of .047, and RMSEA of .063, indicating that the model consisting of the 22 items of the two questionnaires was appropriate. Analysis of the concurrent validity of the two tools indicated a high correlation coefficient (.903) and high correlation (.571-.846) among the subfactors. In conclusion, both the STMI and STS are valid quantitative measures of systems thinking, and it can be inferred that the systems thinking of Vietnamese high-school students can be quantitatively measured using the 22 items identified in our analysis. Using the tool validated in this study with other tools (e.g., qualitative assessment) can help accurately measure Vietnamese high school students' systems thinking abilities. Furthermore, these tools can be used to collect evidence and support effective education in ODA projects and volunteer programs.

This study aims to develop a reliable and valid Geriatric Reaction Inventory-Simplified Form (GRI-SF). Reaction inventory for measuring anger (Evans & Stangelang, 1971) is an assessment tool in a view of stimuli for measuring the level of anger invoked from the anger-triggered experiences. Yet, the inventory, comprised of 76 items, is sometimes incapable of finishing up the lengthy questionnaire. In the sense, a simplified form of RI is necessary for those lacks cognitive ability such as stroke patients or the elderly. In study 1, a full version of Reaction Inventory was given for the elder who are above 60, and ten items out of 76 was selected to form GRI-SF based on the psychometric theory. In study 2, the reliability and validity of GRI-SF was tested by another sample group of elderly with some additional examinations. The reliability was good with Cronbach's alpha of 0.79. Based on the fact that GRI-SF measures the personal trait anger, GRI-SF should not be only strong correlation with the scores of trait anger strongly, but be less correlated with scores representing other aspects of anger. As a result, GRI-SF score showed strong correlations with trait anger among other sub-categories of State-Trait Expression Inventory (STAXI), and was less correlated with anger-out score which reflects behavioral aspect of anger. Moreover, it is less correlated (r=.41) with hostility representing attitudinal or cognitive aspects of anger. Consequently, GRI-SF, constructed by this research, is verified to be a reliable and valid tool for anger measurement.

This study was designed to verify reliability and feasibility by analyzing elderly drivers' ability test tools for older drivers aged 65 or older, which were improved in 2018 and are currently being conducted by the Korea Highway Traffic Authority. Only those aged 65 or older who voluntarily applied to the elderly driving ability evaluation system implemented by the Seoul branch of the Korea Highway Traffic Authority. The research was conducted for about 50 days until Aug. 31, 2018, starting with the registration and inspection of the first study subjects. The analysis performed a correlation analysis with existing tools and cognitive testing tools (MMSE_K) to determine their feasibility and reliability as an improved tool in 2018. As a result, the first, the speed distance, time-space memory, and dispersionism of each sub-component of the old version showed statistically significant static correlation with the sub-factor of the current version. Persistence, on the other hand, was not statistically significant to the current version. The limitations of this study were as follows. Most of the people in the study were highly educated and residents in the metropolitan area. Therefore, it is likely that the results of MSE_K, which checks cognitive and judgment skills, have been upgraded. Also, cognitive tools that are measured by computers are likely to have real measurement errors for generations who are not familiar with computers. Therefore, it is expected that improvement and development of tools for improving the limit points at the site and assessing actual operation capability will be required.

The reliability of the results of LCC analysis is determined by accurate analytical procedures and energy data from which the uncertainty is removed. Until now, systems that can automatically measure these energy data and produce databases have not been commercialized. Therefore this paper proposes a concept model of an S-LCC platform that can automatically collect and analyze electric energy consumption data of equipment systems using the IOT, which is the core tool in the Fourth Industrial Revolution and operates the equipment system efficiently using the analyzed results. The proposed concept model was developed by the convergence of existing BLCS and IOT and was comprised of five modules: Facility Control Module, LCC Analysis Module, Energy Consumption Control Module, Efficiency Analysis Module, and Maintenance Standard Reestablishment Module. Using the results of LCC analysis deduced from this system, the deterioration condition of an equipment system can be identified in real-time. The results can be used as the baseline data to re-establish standards for the maintenance factor, replacement frequency, and lifetime of existing equipment, and establish new maintenance standards for new equipment. If the S-LCC platform is established, it would increase the reliability of LCC analysis, reduce the labor force for entering data and improve accuracy, and would also change disregarded data into big data with high potential.
