Purpose: This study attempted to develop a scale that measures the level of patients' recognition of the nurses' care, based on Watson's caring theory, and confirmed its reliability and validity. Methods: The items were developed through a literature review and an expert content validity test. The questionnaires were administered to 285 inpatients of internal medicine and surgical units at two general hospitals. Construct validity was tested using exploratory and confirmatory factor analysis, and reliability was tested using Cronbach's alpha. Results: This process resulted in a preliminary scale composed of 34 items; We used item analysis and five exploratory factor analyses, and consequently selected 14 items composed of three factors (respect, genuineness, and relationality). The confirmatory factor analysis verified the model fit and convergent and discriminant validity of the final items; criterion validity was confirmed with the positive correlation with the measurement scale of the patient-perceived quality of nursing. The overall scale reliability had a Cronbach's alpha of .92, which indicated internal consistency and reliability. Conclusion: The developed scale showed content, construct, and criterion validity, and reliability, as well as convergent validity for each item and discriminant validity between the factors. This makes it suitable for use in a diverse range of future studies on nurse communication using structural equation models.

Purpose: This study developed an instrument to evaluate the health empowerment of North Korean women refugees and examined its validity and reliability. Methods: Through literature review and focused group interviews, 66 preliminary items with three constructs, including perceived control, perceived competence, and goal internalization were selected based on Menon's psychological health empowerment model. A questionnaire survey was conducted with 239 North Korean women refugees in the community from August 31 to September 4, 2020. Content, construct, convergent, and discriminative validity were evaluated. Cronbach's α was used to evaluate the reliability of scale. Results: The final instrument consisted of 31 items with three factors that were identified through confirmatory factor analysis. The convergent validity showed that the correlation coefficient was .52 (p < .001), which confirmed the validity of the developed measurement tool. Cronbach's α for all the items was .94, and Cronbach's α for the factors was .76~.91. Conclusion: This health empowerment scale has been developed to include aspects of health empowerment, provide a conceptual framework, and offer objective indicators to evaluate the effectiveness of a health education program.

Clustering is a method that collects data objects into groups based on their similary. Performance of the state-of-the-art clustering methods is different according to the data characteristics. There have been numerous studies that performed experiments to compare the accuracy of the state-of-the-art clustering methods by applying various kinds of datasets. A common problem of these studies is that they only consider clustering algorithms that yield the most accurate results for a particular dataset. They do not consider what factors affect the execution time of each clustering method and how they are affected. Nevertheless, execution time is an important factor in clustering performance if there is no significant difference in accuracy. In order to solve the problems of the existing research, through a series of experiments using various types of datasets, we compare the accuracy of four representative clustering methods. In addition, we perform practical clustering performance comparisons by deriving time complexity and identifying factors that influences to its performance.

The present study was conducted to determine convergent factors affecting depression in drinker by age. This was a cross-sectional secondary data analysis study that used the raw data from the Korea National Health and Nutrition Examination Survey in 2014 & 2016. The subjects of the present study were 4,446 middle-aged drinker. Variables related to general characteristics, physical and psychological factors were selected. After a sampling plan compound file was created using IBM SPSS 23.0 program, data were analyzed by giving weights. Depression was influenced by gender (30s, 50-60s), income (30-40s, 60s), education (30-40s), number of family members (30-60s), job (30-60s), eating level (30-40s, 60s), hypertension (40s), DM (30-40s), BMI (30-40s), smoking (30s, 50s), exercise (30s), weight control (60s), drinking binge (30-60s), subjective health (30-60s), subjective body awareness (30-50s), stress (30s-60s), quality of life (30-60s). It is required to design preventive interventions and management plans for depression, considering these factors comprehensively.

Neutron production rate in spherically convergent beam fusion(SCBF) device as a portable neutron source strongly depends on the ion current and the grid cathode structure. In this paper, as the process of design and analysis, Design of Experiment(DOE) based on the results by Finite Element Method-Flux Corrected Transport(FEM-FCT) method is employed to calculate the ion current. This method is very useful to find optimal design conditions in a short time. Number of rings, radius of rings, and distance between the grid cathode and center are selected as control factors. From the results in the optimized model, the higher ion current is calculated and deeper potential well is also observed.

Improvements are made to existing primitive cell volume measurement method to provide a real-time analysis capability for the phase analysis of nanocrystalline materials. Simplification is introduced in the primitive cell volume calculation leading to fast and reliable method for nano-phase identification and is applied to the phase analysis of Mo-Si-N nanocoating layer. In addition, comparison is made between real-time and film measurements for their accuracy of calculated primitive cell volume values and factors governing the accuracy of the method are determined. About 5% accuracy in primitive cell determination is obtained from camera length calibration and this technique is used to investigate the cell volume variation in WC-TiC core-shell microstructure. In addition to chemical compositional variation in core-shell type structure, primitive cell volume variation reveals additional information on lattice coherency strain across the interface.

This study is aimed to examine effects of sociodemographic, social relation, and health related factors on risky drinking among early, middle, and older adulthoods. Using the sixth(2013-2016) National Health and Nutrition Examination Survey, separate logistic regression analyses were conducted for women's early adulthood (n=1,143), middle adulthood (n=1,306), and older adulthood (n=875) to test factors associated with risky drinking. For study results, as for women's early adulthood, education, marital status, employment, depressive feeling, and smoking were statistically associated with risky drinking. As for women's middle adulthood, only subjective stress level and smoking were associated with risky drinking. As for women's older adulthood, education, suicidal ideation, and subjective health condition were associated with risky drinking. These results found different factors influenced risky drinking according to life stages. Based on these results, convergent implications about reducing risky drinking according to life stages of women were discussed.
