This study has an objective to analyze the causal relationship between the emotional labor of the members in the private security firms and its effect on their job stress and validity of the organization. To carry out the study, I established a population of private security guards working at the security firms in Seoul. Then a total of 700 question naires were sent out for the survey using the random sampling method of clusters. The study was carried out over about four months, from May, 2014 to September, 2014. A total of 676 questionnaires were used for the final data. 24 questionnaires were excluded either because they were not returned or contained extreme value. In this study, a statistical package of SPSSWIN 18.0 and AMOS 18.0 were used in the data analysis and the causal relationship was verified using the covariance structural equation. The analysis showed the emotional labor to have a positive effect on the validity of organization but a negative effect on the job stress at the statistical level of p<.001 and the hypothesis was adopted. The hypothesis regarding the job stress was also adopted because job stress was found to have a negative effect on the validity of organization at the statistical level of p<.001. In addition, job stress was found to have a negative effect on the relationship between the emotional labor and validity of organization at the statistical level of p<.001. As a result, the hypothesis about the job stress would function as the parameter was only partially adopted.

This study was done to evaluate current spiritual distress assessment tools and to assess nursing research adapted this spiritual distress assessment tools. Spiritual distress assessment tools were identified through systematic review. Ten studies about spiritual distress assessment tools were identified. In these studies, three international and one domestic standardized assessment tools were found. The purpose of developing these tools was to provide spiritual care through assessing spiritual distress. Domestic assessment tool had low reliability, was not proved by constructive validity, and did not include multidimensional spiritual concepts. International assessment tools may take into account cultural and religious backgrounds in the context for cultural adaptation of instruments. Based on these results, the development of Korean version of spiritual distress assessment tool is recommended.

In case high strength steels are applied for press-formed automotive parts, it is very difficult to secure forming accuracy due to large springback compared to moderate strength steels. In this study, a repetitive step-wise forming analyses based on secant method was proposed as the die design method for mandrel(bending tool) for the 2-axis bending equipments. A bending die with circular mandrel was designed for the DP780 blow motor case of which diameter and thickness are 70.8mm and 2.0mm respectively. Forming tests were performed to verify the validity of established die design and the results were compared with that of conventional HGI(Hot galvanized iron steel) blow motor case. For additional improvement in forming accuracy, an elliptical mandrel was proposed and its validity was verified using forming analyses based on secant method.

This study aims to analyze the premium hamburger market, which has recently become popular, the effect of the importance of the customer selection attribute of premium hamburgers on customer satisfaction, and the effect of customer satisfaction on repurchase intention. Existing research has focused on the importance of the selection attributes of premium hamburgers. Quality, convenience, experience, and presentation visuals were selected as customer selection attributes. This study analyzed 158 customers who had purchased and tasted premium hamburgers. To verify reliability and validity, a confirmatory factor analysis and discriminant validity analysis were performed, and a path analysis was carried out using structural equation modeling. The results showed that the quality, convenience, experience, and presentation visuals of premium hamburgers had a statistically significant effect on satisfaction. Moreover, satisfaction was verified to have a significant effect on repurchase intention. Customers' preference for premium burgers will continue to increase, thanks to the growth in national income, single-person families, and healthy food wellness. It was empirically proven that the selection attributes of premium burgers have a statistically significant effect on customer satisfaction and that satisfaction significantly affects repurchase intention. This study broadens the research horizon and has practical implications.

Objective : The aim of this study was to verify validity of the Activity Participation Assessment for school-age children. Methods : A questionnaire consisting of 30 items from the APA, 75 items from the PACS, and 55 items from the CAPE was administered to elementary school students. A total of 207 questionnaires were analyzed. Confirmatory factor analysis was performed to confirm the construct validity of the APA. Convergence validity and discriminant validity were verified with the average variance extracted (AVE) and the square of the correlation coefficient. The discriminant validity was the Pearson correlation coefficient of the APA, PACS, and CAPE. Results : The results of the analysis were as follows: 1) For construct validity, the goodness of fit of the modified hierarchical second-order factor model was found to be appropriate (p < .001), 2) For convergent validity, the AVE was higher than .50 for all latent variables, 3) For discriminant validity, the AVE of the latent variable was greater than the square of the correlation coefficient (0.239), 4) For concurrent validity, the correlation between the total sum of the APA and PACS scores showed a positive correlation in all domains, and the correlation coefficient ranged from .303 to .647 at a statistically significant level (p < .01), 5) The correlation coefficient between the total sum of the APA and CAPE scores was .490 for recreational activities, .329 for physical activities, .571 for social activities, .401 for skill-based activities, and .390 for self-improvement activities. All domains showed a positive correlation, and were statistically significant (p < .01). Conclusion : APA can be used as a valid assessment tool to measure the participation of school aged children.

The aims of this study was to verify the validity using group comparison method and test/retest reliability of the Communication Behavior Scale for Nurses Caring for People with Dementia(CBS-D). The subjects were nurses who have worked at elderly care facilities in D, U and Y cities(n = 67), and nurses who have worked at general hospitals in D and U cities. The scores of the communication behaviors of nurses working in elderly care facilities were significantly higher than those of nurses working in general hospitals(t=2.49, p=.014). The Intraclass Correlation Coefficients for the test-retest reliability test was .813. Therefore, it was confirmed that CBS-D is an appropriate evaluation tool for evaluating the level of the nurse's communication behavior through various logical analyzes, and it is expected that it can be used in various ways for nursing care for people with dementia.
