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.

Most of the researches on the view of marriage from 1970s until now have merely been the status survey to get a glimpse of thoughts on the marriage of the time. It is true that the recognitions of marriage in the recent days, especially those of the youth are going through a great deal of changes. However, it is also recognized that although westernized views on marriage recently are flooding in, still the traditional perspectives are firmly rooted underneath. Therefore, this study intended to predict the potential conflicts from diversified marital perspectives of the youth in the contemporary society applying the Korean views on marriage as an effort to develop views on marriage in scientific way, analyze the psychological problems before and after marriage, and pursue successful marriage to form a stable and desirable family. As for the method, questions were selected by 275 university students and the validity and reliability of marriage views by 1,283 married couples were examined. As a result, the following conclusions were made. The scale for Korean marriage values were summarized to six factors - 'traditional marriage', 'successful marriage', 'irrationality of marriage', 'necessity of marriage', 'cohabitation', and 'divorce and remarriage', showing high correlation with the existing scales, and the reliability coefficient of each subscale indicated as comparatively reliable with the value of Cronbach α=.88 at Cronbach α=.63.

With rapid economic growth, the urban environment has created a problem of human physical and mental illness. In order to solve these problems, urban forests have emerged as a way to mitigate the environmental risks through improving the polluted environment of the city and improve the quality of life. As the urban forests have expanded, the school forests movement has also been taking an important place recently. The study focused on the performance of school forests by comparing the perceptions among teachers and students about their functions. The questionnaire was composed of 4 questions concerning human matters, 10 questions for space recognition, 4 questions for thermal environment, 2 questions for health promotion, and 20 total questions for composition of survey items. The reliability of the school forest function, number of tree planting areas and quantities, the harmony of the planting, and the satisfaction of the school forest were analyzed in the questionnaire conducted by the school members. Although it does not recognize school forests, it has a positive response to the green space that is built outdoors. It is considered that outdoor education and environmental education are sufficient in school forests and green spaces. The results showed that the outdoor green space was more satisfactory when compared with the general school. Teachers and students' preferences were similar to 'seasonal changes' and' trees of various colors and shapes'. The reliability analysis between each item shows that the coefficient for cronbach's ${\alpha}$ was .700 to .834. The purpose of this study is to identify the perception of forest function among school forest members and to utilize them as a basic data in the future.

Purpose: To evaluate the applicability of Lasater Clinical Judgment Rubric (LCJR) as an evaluation tool for hypoglycemia simulation practicum on Korean nursing students. Methods: The methodological study was done to evaluate the reliability and validity of the LCJR. Based on Benner's 4 levels of nursing grading rubric, ten items of the LCJR was evaluated for interrater reliability and internal consistency. The content validity was tested by eight experts and concurrent validity was done by Clark (2006)'s clinical simulation grading rubric. Fifty five video-taped cases of senior nursing students in Y University were used for the reliability and concurrent validity of the LCJR. Results: The interrater reliability was r=.90 (p<.001); Kendall tau b=.87 (p <.001), and Cronbach's alpha was .90. A value of item content validity index of the LCJR was .97 and correlation coefficient between the LCJR and Clark's instrument was .90 (p<.001). The mean (${\pm}SD$) of the nursing students' clinical judgment was 2.04 (${\pm}50$). Conclusion: The LCJR is a useful tool to examine the simulation performance evaluation for improving competency among nursing students. The results indicated that the LCJR may provide valuable information regarding clinical judgment of nursing students and thus, suggested to use to develop a simulation-based education program.

This study aims to investigate the influence of engagement of augmented reality game on immersion. The relationship between engagement and flow was examined through the mediating effects of emotional attachment and focus of attention on presence and the mediating effects of presence on flow. In order to verify the research hypothesis, online questionnaire was conducted with the consent of $Pok\acute{e}mon$ Go game user group. The questionnaire items were translated from the Augmented Reality Immersion Questionnaire. A total of 200 questionnaires were collected and used for analysis. Using the SPSS 23.0 program and the Mplus 7.0 program, the reliability of the scale was confirmed through the Cronbach's coefficient and the causal relationship and the mediating effects were verified by path analysis. As a result, there was no direct causal relationship between engagement and flow. However, causal relationship was evident when emotional attachment and focus of attention were mediated in the process of engagement in augmented reality game. In conclusion, systematic explanations of participant's emotional attachment and attentional state as a main factor in the process of participating in the augmented reality game involvement, reveal the elements to be noticed by the augmented reality game.

Purpose: To develop the stress coping behavior measurement scale(SCBMS) for the workers in manufacturing industry. Methods: Developing of SCBMS was based on job stress and psycho-social health status. Job stress and psycho-social health status were estimated by using the Karasek's job content questionnaire (JCQ) and the general health questionnaire (GHQ-28), and the general characteristics for subjects were estimated by self-reported questionnaire and interview. Result: The subjects were 456 male workers who had never been occupationally exposed to hazardous chemical and other materials, was mean age 31.27 years and mean work duration was 4.81 years. As a result of factor analysis for developed stress coping questionnaire, four factors were extracted such as inactive, active, health and emotional behavior from 15 question items of stress coping questionnaire. Fifteen items passed for item internal consistency (100% success rate) and item discriminant validity (100% success rate). Cronbach's alpha coefficient for each factor ranged from 0.56 to 0.77. The active behavior correlated positively with job demand of JCQ (r=0.12, p<0.05), but total GHQ-28 was negatively correlation (r=-0.24, p<0.01), respectively. Conclusion: These results demonstrated the reliability and validity of SCBMS. Thus, the results may prove to be a useful assessment tool in evaluating stress coping behavior.

This study was done to develop a eating behavior scale for high school girls using Stunkard and Messick(1985)'s three factors(dietary restraint disinhibition, hunger) as a conceptual framework and to test the validity and reliability of the scale. The subjects were 202 high school girls. The convenience sample is consist of 96 normal weight and 106 obese girls. Data were collected between October 28 and November 25 in 1996 and analyzed using the SPSS package. The new 32-item scale measuring these factors is presented 1. Three stable factors emerged and these contributed 45.7% of the variance in the total score. All 32 items loaded above .35 on each factor, 2. Factor 1 was named disinhibition(14 items), factor 2 was named cognitive restraint of eating(10 items), factor 3 was named hunger(8 items). Comparison of factor Ⅰ, factor Ⅱ, factor Ⅲ between normal subjects and obese subjects showed that there was a significant difference in factor Ⅱ & Ⅲ, not in factor Ⅰ. 3. Cronbach's alpha coefficient for internal consistancy was .9393 for total 32 items and .8820, .8652, .8490 for three dimensions of eating behavior in high school girls. Recommendations are suggested below : 1. Replication study with appropriate age groups be done to test validity and reliability, 2. The present developed scale must be a reliable measure of eating behavior and should have utility in further study on how effective nursing intervention related to different kind of groups such as disinhibition group and cognitive restraint of eating group. 3. To extend validity of the scale, further study is needs using more larger subjects which is consists of dieters and free eaters.

Purpose: This study aimed to develop the Korean Prototype of Wellness Index (KP-WI) and identify the relationship between Koreans' health characteristics and wellness. Methods: The Wellness Index (WI) was translated into the primitive version of the KP-WI, considering the Koreans' culture and health behavior. It was administered to 223 service industrial employees at one workplace along with the Positive Affect and Negative Affect Schedule (PANAS) and Stress Questionnaire-Short Form. Data analyses included item-total correlation, Pearson's correlation coefficient, independent t-test, and one-way ANOVA. Results: The primitive version was modified to KP-WI based on the item-total correlation. The items considered to lower the reliability of the KP-WI were eliminated. Cronbach's ${\alpha}$ for each subscale ranged from .857 to .939. Perceived stress and negative emotions correlated significantly with wellness measured by KP-WI (r=-.29, p<.001; r=-.27, p<.001). Positive emotions correlated significantly with wellness (r=.60, p<.001). Conclusion: This study contributes to the development of Korean-style wellness indexes by developing a prototype and exploring the factors related to wellness.

Background: The "health-related quality of life" (HRQL) for patients with chronic respiratory disease has been emphasized, because chronic respiratory disease (CRD) is chronic and progressive, and it finally causes disability. HRQL instruments may be useful for monitoring patients' progress or for determining the most appropriate choice of treatment. We describe the adapting St George's Respiratory Questionnaire (SGRQ), which is a self-administered questionnaire developed by Jones et al. (1991), into the Korean version for covering three domains of health for the patients suffering with airways disease. Method: We obtained the original SGRQ from the author after gaining permission. For adaptation, we created an expert panel and translated the original questionnaire into Korean language. The translated questionnaire was then back-translated by bilingual experts and we compared it with the original questionnaire. After correction and feasibility testing, 74 patients with chronic respiratory disease (COPD, asthma, destroyed lung) completed the Korean version of the SGRQ. The clinical status of each patients was evaluated concurrently with measurement of their health status. Result: The Korean version of the SGRQ was acceptable and easy to understand. Cronbach's alpha reliability coefficient was 0.92 for the overall scale and 0.63 for the "Symptoms", subscale, 0.87 for the "Activity", subscale, and 0.89 for the "Impacts" subscales. The correlation coefficients between the overall score and the Borg scale score, oxygen saturation, and forced expiratory volume in one second ($FEV_1$) were 0.52, -0.32 and -0.26, respectively. These results support that the Korean SGRQ was correlated with other measurements. Conclusion: The Korean SGRQ was reliable and valid for patients with chronic respiratory disease, such as COPD, asthma, and destroyed lung. The SGRQ score was well correlated with other respiratory measurements as well. Although further studies should complete the adaptation work, our results suggest that the SGRQ may be used in Korea and also for international studies involving Korean CRD patients.
