Comprehensive condition monitoring of large industry systems such as nuclear power plants (NPPs) is essential for safety and maintenance. In this study, we developed novel system-scale diagnostic technology based on deep-learning and IR thermography that can efficiently and cost-effectively classify system conditions using compact Raspberry Pi and IR sensors. This diagnostic technology can identify the presence of an abnormality or accident in whole system, and when an accident occurs, the type of accident and the location of the abnormality can be identified in real-time. For technology development, the experiment for the thermal image measurement and performance validation of major components at each accident condition of NPPs was conducted using a thermal-hydraulic integral effect test facility with compact infrared sensor modules. These thermal images were used for training of deep-learning model, convolutional neural networks (CNN), which is effective for image processing. As a result, a proposed novel diagnostic was developed that can perform diagnosis of components, whole system and accident classification using thermal images. The optimal model was derived based on the modern CNN model and performed prompt and accurate condition monitoring of component and whole system diagnosis, and accident classification. This diagnostic technology is expected to be applied to comprehensive condition monitoring of nuclear power plants for safety.

Purpose: The purpose of this study was to develop and establish the psychometric properties of a clinical nursing competency evaluation tool to be utilized by clinical preceptors. Methods: The initial items were identified through in-depth literature review and field interviews based on a hybrid model. Content validation of the items was evaluated through three rounds of content validity testing. Participants were 34 clinical preceptors and 443 nursing students participating in clinical practice. Data were analyzed using exploratory and confirmatory factor analysis, convergence and discriminant validity, internal consistency and inter-rater reliability. Results: The final scale consisted of 23 items and four factors, fundamental nursing skills performance, critical thinking skills based on the nursing process, basic nursing knowledge, and professional attitude; these factor explained 69.7% of the total variance. The analysis with multi-trait/multi-item matrix correlation coefficients yielded 100.0% and 95.7 % convergence and discriminant validity, respectively. Cronbach's alpha for the total items was .95. The four subscale model tested by confirmatory factor analysis was satisfactory. Inter-rater reliability ranged from .912 to .967. Conclusion: This scale was found to be a reliable and valid instrument that clinical preceptors can apply for evaluating the clinical nursing competency of nursing students in clinical settings.

The concept of 'Employer branding' (EB) - one effective and sustainable strategy to attract and retain talent - has received a lot of attention from researchers and business managers. This concept becomes more meaningful when the 'war of talent' takes place in an extremely fierce manner in Vietnam as well as around the world. However, this concept is rather new; as a result, many points related to 'EB' scales should be improved, especially in Vietnamese context. Therefore, this study focuses on developing and confirming the EB scale in the context of Vietnam. Based on EB theory, this research applies the mixed research method: qualitative methods (expert interview and group discussion) and quantitative method (questionnaire survey of 937 respondents). EB is demonstrated to be a quadratic concept, consisting of the following 10 dimensions: Corporate social responsibility (CSR), Promotion (PRO), Work-Life Balance Satisfaction (WLSA), Education (EDU), Behavior-based Family interference with work (WLBE), Travel opportunities (TRA), Time-based work interference with family (WLTI), Teamwork (GRO), Supporting (SUP), and Strain-based family interference with work (WLST) with 58 observed variables. Based on the survey towards the employees in enterprises and organizations in Vietnam, the analysis results affirm that this scale ensures efficiency, reliability, unidirectionality and convergent values.

Purpose: This study aimed to develop a self-assessment tool to evaluate program outcomes of nursing students in Korean nursing undergraduate education. Methods: The instrument development process consisted of literature review, focus group interviews, and item validation. A total of 117 items were analyzed through content validity testing. Data was gathered from 302 nursing students in Korea and analyzed using SPSS 21.0. Results: To construct validity, principal component analysis and Varimax rotation were used, and 12 factors, with a cumulative explanatory variance of 69.16%, were determined from 79 items. For internal consistency and reliability, Cronbach's ${\alpha}$ was .91. The half-split reliability results were .84 and .85, and the ROC curve showed an optimal cutpoint at 227. A five-point Likert scale was used for scoring. Conclusion: This instrument was found to have fair validity and reliability as a self-assessment tool for nursing student learning outcomes. Therefore, it can be used to evaluate program outcomes indirectly in nursing schools.

Purpose: The purpose of this study was to develop a valid Adult Fall Assessment Scale Korean version (FAS-K) for inpatients in general hospitals in Korea. Methods: This a 14 item FAS-K was developed based on a review of national and international research and expert opinions in related field. Interrater reliability of FAS-K was analyzed using the ICC (Intraclass Correlation Coefficients). To examine the validity of FAS-K, a CVI (Content Validity Index), the Pearson correlation coefficients between FAS-K and two widely used scales, the Morse Fall Scale (MFS) and the Johns Hopkins Hospital Fall Risk Assessment Tool (JHFRAT), and the Mann-Whitney test were used. Results: The ICC was .958. The CVI ranged from .70 to 1.00. The FAS-K was significantly associated with the MFS (r=.74, p<.001) and with the JHFRAT (r=.87, p<.001), verifying the concurrent validity of FAS-K. As for the construct validity of FAS-K, significant differences between the fall and non-fall groups were found not only in the MFS (Z=-3.23, p=.001) but also in the FAS-K (Z=-3.10, p=.002). Conclusion: The findings indicate that the FAS-K is a reliable fall risk assessment tool with high validity.

Objectives Development of objective clinical measure for analyzing pediatric weakness has been studied. However, there is no gold standard clinical measures with acceptable validity and reliability were not provided yet and these has been major issue for clinics. Methods Some Korean medicine hospital outpatients (n=324) were recruited as participants, and 55 preliminary questions were given. Pediatric Weakness Scale (PWS) with five subscales and thirty questions were developed using factor analysis and item analysis. The internal consistency of PWS subscales were examined with using Cronbach's alpha. The correlations between PWS subscales and physical characteristics of Body Mass Index (BMI) and Ponderal Index (PI) were attested using Pearson's correlation. The differences between PWS subscale scores and profiles among 3 to 13 years old children were examined using profile analysis and ANOVA by gender. Results PWS five subscales explained 49.1% of total variance, and the range of Cronbach's alpha was from 0.700 to 0.803. The range of correlation coefficient between PWS total score and five subscales was from 0.643 to 0.748, and the PWS total score was significantly (p<0.001) correlated positively with BMI (r=-0.237) and negatively with PI (r=-0.280). The scores and profiles of PWS five subscales, BMI and PI were found to be significantly different among the all age groups. Conclusions Objective and validated clinical measure for analyzing pediatric weakness with five subscales was developed in current study, and foundations for screening, managing and treating pediatric weakness during the development were established as well. This study would contribute to the integrative education and clinical practice of the Eastern and Western medicine.

Background There is a growing concern in the field of aesthetic surgery about the need to measure patients' expectations preoperatively. The present study was designed to develop and validate the Expectations of Aesthetic Rhinoplasty Scale (EARS), and to compare expectations between rhinoplasty patients with and without body dysmorphic disorder (BDD). Methods In total, 162 college students and 20 rhinoplasty candidates were recruited. The measures included the newly developed EARS, a measure of psychopathology, and demographics. The DSM-IV structured clinical interview for BDD was used to confirm the diagnosis in rhinoplasty patients. Results The EARS was constructed of six items based on their significant content validity. In the scale development phase, Cronbach's alpha was 0.87. The test-retest reliability coefficient of the scale was satisfactory (intraclass correlation coefficient, 0.94; 95% confidence interval, 0.82-0.98) over a four-week period. Scores on the EARS were significantly positively correlated with psychopathological symptoms (r=0.16; P<0.05). Moreover, comparison of EARS scores between BDD (M=25.90, standard deviation [SD]=6.91) and non-BDD rhinoplastic patients (M=15.70, SD=5.27) suggested that BDD patients held significantly higher expectations (P<0.01). Conclusions The expectations of aesthetic rhinoplasty patients toward surgery may play a crucial role in their postoperative satisfaction. While the value of patients' expectations is clinically recognized, no empirical study has measured these expectations in a psychometrically sound manner. The current study developed and validated the EARS. It may be easily used as a valid and reliable instrument in clinical and research settings.
