Purpose: This study evaluated the validity and reliability of Shively and colleagues' self-efficacy for HIV disease management skills (HIV-SE) among Korean participants. Methods: The original HIV-SE questionnaire, comprising 34 items, was translated into Korean using a translation and back-translation process. To enhance clarity and eliminate redundancy, the author and expert committee engaged in multiple discussions and integrated two items with similar meanings into a single item. Further, four HIV nurse experts tested content validity. Survey data were collected from 227 individuals diagnosed with HIV from five Korean hospitals. Construct validity was verified through confirmatory factor analysis. Criterion validity was evaluated using Pearson's correlation coefficients with the new general self-efficacy scale. Internal consistency reliability and test-retest were examined for reliability. Results: The Korean version of HIV-SE (K-HIV-SE) comprises 33 items across six domains: "managing depression/mood," "managing medications," "managing symptoms," "communicating with a healthcare provider," "getting support/help," and "managing fatigue." The fitness of the modified model was acceptable (minimum value of the discrepancy function/degree of freedom = 2.49, root mean square error of approximation = .08, goodness-of-fit index = .76, adjusted goodness-of-fit index = .71, Tucker-Lewis index = .84, and comparative fit index = .86). The internal consistency reliability (Cronbach's α = .91) and test-retest reliability (intraclass correlation coefficient = .73) were good. The criterion validity of the K-HIV-SE was .59 (p < .001). Conclusion: This study suggests that the K-HIV-SE is useful for efficiently assessing self-efficacy for HIV disease management.

This study is a descriptive research study to analyze the effects of grit in nursing students on self-directed learning ability and adjustment to university life. Data was collected from 260 nursing students including first and second-year nursing students in Region C University. The data was analyzed to find relationships among grit, self-directed learning ability, and college life adjustment using frequency analysis, descriptive statistics, t-test, ANOVA, and multiple regression analysis. The results showed the subdomains of grit in which grit in nursing students affected self-directed learning ability were consistency of interest (t=2.423, p<.05) and perseverance of effort (t=3.761, p<.001). The explanation power of the regression model was 40.2%, which was a statistically significant result (F=23.609, p<.001). The subdomains of grit in which grit in nursing students affected adjustment to college life were the consistency of interest (t=3.112, p<.001) and perseverance of effort (t=3.930, p<.001). The explanation power of the regression model was 43.2%, which was a statistically significant result (F=30.608, p<.001). These results show that it is necessary to develop educational programs to enhance individual nursing students' grit, self-directed learning ability, and college-life adjustment.

Objective : This study aims to verify the validity and reliability of the Korean version of the Sensory Processing and Self-Regulation Checklist (SPSRC) for children with and without autism spectrum disorder. Methods : The Pearson product-moment correlation coefficient was calculated using Short Sensory Profile (SSP) to verify concurrent validity. Construct validity was verified by comparing the sensory processing ability and self-regulation ability of the two groups. Cronbach's α was calculated in the case of internal consistency for reliability verification, and the test-retest reliability was verified through the Pearson correlation coefficient. Results : Based on the verification of the concurrent validity, the Korean version of SPSRC and SSP showed a statistically significant correlation (p < 0.01). The construct validity was found to have a statistically significant difference between the two groups in the area and sub-items of the Korean version of SPSRC (p < 0.001). For the internal consistency, Cronbach's α ranged from 0.700 to 0.975. The test-retest reliability showed that the correlation coefficient ranged from 0.937 to 0.997. Conclusion : The Korean version of SPSRC was confirmed to be an evaluation tool with high validity and reliability. It is expected to be used as an evaluation tool for planning treatment goals in clinical trials and as a meaningful basis for future research.

The purpose of this study was to test the construct validity and reliability of the Health Self-Determinism Index for Children (HSDI-C), an instrument designed to measure intrinsic motivation in health behavior. An convenience sample of 558,7 to 13 years old children completed the Korean version of HSDI-C. The findings were as follows : 1. Construct validity was supported through factorial isolation of four theory-consistent subscales ; Internal-external cue responsive ness, Self-determinism in health judgement, Competency in health matters, and Self-determinism in health behavior /goal. The total percent of variance explained by 4 factors was 2 percent. 2. The correlations between the four factors were ranged from -.06 to .29 indicating that factors are not redundant and each factor contributes uniquely to the total construct. 3. Cronbach alpha coefficient for internal consistency was .96 for the total, and .72, .56, .69, and .75 on the respective subscales. Test-retest reliability for the total scale was .85 at 2 weeks. 4. The Analysis of variance for the HSDI-C total scale and subscales according to grades revealed that there were significant differences in means for the total and factor one and two, indicating younger children were more extrinsically motivated.

This study describes the optimum mix proportion of the high strength and self-compacting concrete placed in main structures of LNG above tank. This concrete requires high strength level about $60{\sim}80MPa$, low hydration heat, balance between workability and consistency without vibrating in the actual work. For this purpose, low heat portland cement and fly ash are selected and design factors including water-binder ratio, replacement ratio of fly ash are tested. As experimental results, low heat portland cement shows lower the confined water ratio than another cement type and the optimum replacement ratio of fly ash in order to improve properties of the binder-paste shows 10% by cement weight considering test results of the confined water ratio$({\beta}p)$. Also, flowability of the high strength and self-compacting concrete by using fly ash about $10{\sim}20%$ is improved. The replacement ratio of fly ash 10% and water-binder ratio $25{\sim}27%$ are suitable to the design strength 80MPa and cost, In case of the design strength 60MPa, the replacement ratio of fly ash and water-binder ratio show 20% and $25{\sim}30%$ separately. Based on the results of this study, the optimum mix proportions of the high strength and self-compacting concrete will be applied to the construction of LNG above tank as a new type.

The purpose of this study was to develop a self-management program for patients suffering from coronary artery disease (CAD), based on the self-determination theory and subsequently perform a heuristic evaluation by professionals and a quality assessment by users. The program consisted of 6 main menus and 20 submenus. Heuristic evaluation was conducted using eight principles, and as a result, a score of 1 was assigned by a professional for five principles: consistency and mapping, good ergonomics and minimalist design, flexibility and efficiency, anesthetics, and error management. Two professionals gave the principles of ease of input, screen readability, and glanceability a score of 1. In the quality assessment by the users, the system quality category had the highest score of 4.6 out of 5, and information quality had the lowest score of 3.87 out of 5. The overall average score was 4.08, which indicated the general satisfaction regarding the quality of the application. We have reflected on all the recommendations provided by the professionals based on their heuristic evaluation and incorporated them in the program.

This study was undertaken to observe the influence of the model image and self-image congruence of consumers in Korean cosmetic advertisements on the advertising attitude and analyze the relationship between self-image congruence and advertising demand type, participation, and advertising effect, and to help develop plans to more effectively communicate advertising images. The experimental design of this study was 2 (self-image congruence: consistency vs. inconsistency) × 2 (advertising appeal: rational appeal vs. emotional appeal) × 2 (involvement: high vs. low) three-way ANOVA. The results of the study showed that the interrelationship between self-image congruence and advertising appeal type and involvement played an important role in determining the advertising attitude. More specifically, firstly, the self-image congruence of consumers in Korean cosmetic advertising affected the advertising attitude. Secondly, in the advertisements of Korean cosmetics, consumers preferred a rational advertising appeal to an emotional advertising appeal. Finally, statistical results showed significant differences in the influence of the interaction effect of the self-image congruence status of consumers and the advertising appeal on the attitude of advertising. The Korean cosmetic involvement of consumers had a significant impact on whether the Korean cosmetic advertising model image and consumer self-image were consistent with the type of advertising appeal and on the interaction effect of advertising attitude.

Purpose: The purpose of this study was to develop and validate a diabetes management self-efficacy scale for older adults (DMSES-O). Methods: A preliminary DMSES-O of 22 items was derived from a literature review and seven domains of self-management behaviors. Content validity was confirmed by experts in diabetes self-management education. To test the reliability and validity of the DMSES-O, data were collected from 150 older adults with type 2 diabetes. The data were analyzed using exploratory factor analysis, and Cronbach's ${\alpha}$ and Pearson's correlation coefficients were calculated. Results: From the exploratory factor analysis, 17 significant items in six subscales were derived. Factors derived were named "problem solving for hypoglycemia and self-monitoring blood glucose," "problem solving for hyperglycemia," "coping with psychological distress and taking medication," "reducing risks of diabetes complications," "appropriate exercise," and "healthy eating." The criterion-related validity of the DMSES-O was established by its correlation with the Summary of Diabetes Self-care Activities Questionnaire. Cronbach's ${\alpha}$, a measure of internal consistency, was .84 for the overall scale and ranged from .54 to .80 for the subscales. Conclusion: The DMSES-O is a reliable and valid instrument to measure selfefficacy for diabetes self-management among older adults.

Hotel practitioners are searching for leadership typology to maximize employees' capabilities and consistency in their attitude. Also, they are increasingly interested in their employees' traits which constitute and influence their job attitude. This study sought to investigate the impact of servant leadership mediated through self-leadership on employees' job attitude. Focused on hotel restaurant employees, representing 15 hotels in Seoul Metropolitan Area, a survey was conducted and 272 respondents out of 297 were empirically analyzed. The collected data was analyzed with the SPSS 12.0 for Windows and AMOS software program. Structural equation modeling was conducted to test the hypotheses. The results suggested that servant leadership has a significant impact on self-leadership. Furthermore, self-leadership was found to have a significant impact on job satisfaction. However, direct influence of self-leadership on organizational commitment was not found. Finally, servant leadership was found to have a direct impact on job satisfaction. On the other hand, servant leadership positively influences on organizational commitment when mediated through self-leadership. In addition, this study provides practical implications for hotel restaurant professionals in linking servant leadership mediated through self-leadership to job attitude.
