  • Purpose: The aim of this study was to evaluate the reliability and validity of the Korean version of the Wong and Law Emotional Intelligence Scale (K-WLEIS). Methods: Data were collected from 360 nursing students using a self reported questionnaire. Exploratory and confirmatory factor analysis were used to test construct validity. Convergence validity was identified by correlation with communication competency. Item convergent and discriminant validity were also analyzed. Reliability was evaluated internal consistency and test-retest reliability. Results: The results of exploratory factor analysis showed that the eigen values ranged from 1.34 to 5.86 and 73.2% of the total explained variance. Confirmatory factor analysis showed adequate model fit indices (χ2/df 1.89, RMSEA .07, GFI .89, CFI .95, and TLI .93) and standardized factor loadings (.48 to .87). The average extracted variances (.71 to .79) and composite reliability (.80 to .87) validated convergence and discriminant validity of the items. Test-retest reliability of intra-class correlation coefficient was .90 and the Cronbach's alpha coefficient was .88. Conclusion: The K-WLEIS is an appropriate scale for measuring the emotional intelligence of Korean nursing students. Therefore, it is expected that the K-WLEIS will be used for nursing education programs to improve nursing students' emotional intelligence.

  • Purpose: This descriptive survey-based study aimed to identify the factors associated with obese adults' quality of life (QOL) using a secondary analysis of data collected through the 8th Korea National Health and Nutrition Examination Survey (2019). Methods: In this study, factors affecting the health-related quality of life of obese adults were analyzed by categorizing them into three independent variables: general characteristics, health behaviors, and mental health characteristics. Using t-test and analysis of variance (ANOVA), an analysis was performed to determine the differences in obese adults' QOL depending on their general characteristics, health behaviors, and mental health conditions. A hierarchical regression analysis was performed to identify the factors that affect obese adults' QOL. Results: In obese adults' general characteristics, the risk factors for QOL were older age, male, lower-income level, presence of spouse, and occupation. With regard to health behaviors, the risk factors were lack of exercise. In terms of mental health conditions, the risk factors were stress and suicidal ideation. Conclusion: Obese adults' QOL was affected by age, sex, income level, absence/presence of a spouse, occupation, health behaviors (e.g., exercise), and mental health conditions (e.g., stress and suicidal ideation).

  • Purpose: The purpose of this study was to develop and evaluate breastfeeding effectiveness scale to measure effectiveness of breastfeeding for mothers in the early postpartum period. Methods: A conceptual framework was constructed from properties of effective breastfeeding (Yang and Seo, 2011), and item construction was derived from literature review and analysis of the data along with interviews with breastfeeding mothers. Content validity was tested by experts. Each item was scored on a five-point Likert scale. The preliminary questionnaire was administered to 248 breastfeeding mothers. Data were analyzed using item analysis, factor analysis, Pearson correlation coefficients, and Cronbach's ${\alpha}$. Results: From the factor analysis, 20 items in seven factors were derived. The factors were identified as mother's satisfaction, suckling, assurance of milk quantity, infant's satisfaction, latching on, infant's feeding desire, and breastfeeding positioning. The seven factors explained 65.1% of total variance, Cronbach's ${\alpha}$ of the total items was .83 and the factors ranged from .44 to .75. Conclusion: Results of this study suggest that breastfeeding effectiveness scale is a reliable and valid instrument to measure breastfeeding effectiveness of mothers in the early postpartum period.

  • Response of buried flexible pipe-soil system is studied, through numerical analysis, with respect to deflection and buckling in a spatially varying soil media. In numerical modeling procedure, soil parameters are modeled as two-dimensional non-Gaussian homogeneous random field using Cholesky decomposition technique. Numerical analysis is performed using random field theory combined with finite difference numerical code FLAC 5.0 (2D). Monte Carlo simulations are performed to obtain the statistics, i.e., mean and variance of deflection and circumferential (buckling) stresses of buried flexible pipe-soil system in a spatially varying soil media. Results are compared and discussed in the light of available analytical solutions as well as conventional numerical procedures in which soil parameters are considered as uniformly constant. The statistical information obtained from Monte Carlo simulations is further utilized for the reliability analysis of buried flexible pipe-soil system with respect to deflection and buckling. The results of the reliability analysis clearly demonstrate the influence of extent of variation and spatial correlation structure of soil parameters on the performance assessment of buried flexible pipe-soil systems, which is not well captured in conventional procedures.

  • Based on Perceptions about Mathematics Teachers (PMT) perceived by high school students, measured by 2189 students from Seoul Educational Longitudinal Study 2014 (SELS 2014), latent profile analysis (LPA) identified five distinct types of student groups (positive, partial positive, middle, negative, extreme negative). These student of positive, middle, and negative groups are positive, moderate and negative perceptions about math teachers. Partial positive group generally had a positive perception about mathematics teachers, extremely negative group was very negative about mathematics teachers. Both of these groups had peculiarly inconsistent trends and several anomalies. The Multinomial logistic regression analyses also indicated that individual factors (gender, major, self-concept, resilience, self-assessment, career maturity), school factors (friendship, relationship with school teachers) and parental factors (academic-relationship, emotional-relationship) were significant predictors of PMT profile groups. The Analysis of variance also indicated that mathematics class (attitude, satisfaction and atmosphere), Mathematics achievement were significant predictors of PMT profile groups. The profiling of perceptions about mathematics teachers resulted in enhanced understanding of the complex range of processes students employed. During mathematics class, implementation of smooth interactions and communications between students and teachers added in the teaching and learning of mathematics.

  • The CAI (Computer-Assisted Instruction) system for science teaching has been increasing both in quantity and in quality during the last two decades. However, science learning by computer has not played a leading role in the science teaching process. Therefore, the purpose of this study was to analyze the effectiveness of tutorial CAI programs according to the learner's characteristics such as sex, inquiry skills, attitudes toward science subject, logical thinking skills, achievement motivation, science content achievement in science teaching. One group pretest-posttest design was used as an experimental design. The three tutorial science CAI programs were used for thirty males and females selected in grade eight. According to the analysis of CAI achievement scores the female students showed significantly higher (P<0.05) than the male students. Also, one-way analysis of variance was used to investigate the effects of interaction between sex and achievement motivation. The significant difference on the effects of interaction between sex and achievement motivation has not found. The effects of tutorial CAI between logical thinking skills, attitudes toward science subject, inquiry skills, achievement motivation, science content achievement according to upper and lower levels were investigated by using the statistical analysis of one-way ANOVA. The results indicate that tutorial CAI might provides a good opportunities for the improvement of science achievement to the lower level students of attitudes toward science subject, inquiry skills, science content achievement.

  • Purpose: The purpose of this study was to develop and validate a Nurse's Character Scale for Care in Clinical settings (NCS_C). Methods: The NCS_C was developed and validated as follows: Item generation, preliminary test of questionnaire, and tests of validity and reliability. One hundred and thirty six preliminary items were developed through a literature review and in-depth interviews by 10 nurse-experts and five patients. The content validity of the items was verified through an evaluation by five nurses and seven professors in the fields of Korean literature, pedagogy and nursing. Finally, 53 items were confirmed through item analysis, factor analysis and validity tests including convergent, discriminant and concurrent validities. Data were analyzed using factor analysis, Pearson correlation coefficients, and Cronbach's alpha. Results: Thirteen factors evolved from the factor analysis, which explained 63.1% of the total variance. The factors referred to the union of two dimensions: the professional dimension and the interpersonal dimension. The internal consistency, Cronbach's alpha, was .95, and reliability of the subscales ranged from .58 to .87. Conclusion: The results of this study suggest that the NCS_C is a reliable and valid primary scale to measure nurses' or students' character level for better care in clinical settings.

  • The study examines the efficiency of private sector banks in India with the help of Window DEA (Data Envelopment Analysis) for a period from 2005 to 2017. With a window of three years, the period was divided into 11 windows. The study outcomes show that 59.9% of all private sector banks in India operate at more than 0.9 level of efficiency, and there are only three occasions when banks were operating at the efficiency value between 0.6 to 0.7. Further, the consistency in the efficiency scores of the banks has also been analyzed using an efficiency mapping matrix, and the mean efficiency score of the bank in each window is studied. The score of standard deviation was interpreted accordingly for these banks. Banks that are showing the highest efficiency scores also have a higher variance of efficiency scores. There was no bank identified in the matrix that promises high-efficiency ratings with low variability. The study concludes that the analysis of the efficiency mapping matrix indicates that, as a DMU escalates in the efficiency scores, the standard deviation reflecting the risk in overall efficiency scores also tends to rise. The findings complement the concept of higher risk to higher return or greater efficiency.
