This study was conducted to test the validity and reliability of the Korean version of the Professional Quality of Life Scale-Short Form (ProQOL-K-SF). Survey data were collected from 191 staff involved in long-term care insurance who worked for National Health Insurance Services. Construct validity using exploratory factor analysis and the internal consistency reliability were determined using SPSS/WIN (21.0). Factor analysis of the ProQOL-K-SF demonstrated that it has a two-factor structure (compassion satisfaction and compassion fatigues) and 13 items that support construct validity. Factor loadings of the compassion satisfaction ranged from 0.70-0.86, factor loading of the compassion fatigues ranged from 0.71-0.82 and the total variance was 60%. The ProQOL-K showed interanal consistency based on Cronbach's ${\alpha}$, with a total scale and two sub scale values of 0.76-0.90. Compassion fatigue and compassion satisfaction of 30 items of the ProQOL-K were positively correlated with those of 13 items of the ProQOL-K-SF. The results support that the ProQOL-K has satisfactory construct validity and is a reliable measure of professional quality of life in Korea.

This study was undertaken to validate and assess the reliability of the Korean version of professional quality of life scale (K-ProQOL) that measures the compassion satisfaction, compassion fatigue and burnout among clinical nurses in Korea. We conducted an internal consistency reliability and construct validity by applying confirmatory factor analysis using SPSS WIN (24.0) and AMOS (18.0). Survey data were collected from 210 nurses working at three tertiary hospitals located in Seoul. Reliable internal consistency was achieved for the K-ProQOL, with a Cronbach's alpha for the total scale and three sub scale values of 0.72-0.90. Factor loadings on three subscales of the 30 items considered ranged from 0.25 to 0.82. The model was validated by confirmatory factor analysis (RMSEA 0.05-0.1, GFI >0.7, CFI >0.7). The findings of this study demonstrate that the K-ProQOL has satisfactory construct validity and reliability to measure compassion satisfaction, compassion fatigue and burnout among clinical nurses in Korea. This is the first study assessing the validity and reliability of the Korean version of professional quality of life scale for clinical nurses in Korea.

Background: This study was guided by principles of the theoretical system of evidence-based medicine. In particular, when searching for evidence of breast cancer, a measuring scale is an instrument for evaluating curative effects in accordance with the laws and characteristics of medicine and exploring the establishment of a system for medically assessing curative effects. At present, there exist few tools for evaluating curative effects. Patient-reported outcomes (PROs) refer to outcomes directly reported by patients (without input or explanations from doctors or other intermediaries) with respect to all aspects of their health. Data obtained from PROs provide evidence of treatment effects. Materials and Methods: In accordance with the tenets of theoretical medicine and ancient medical theory regarding breast cancer, principles for developing a PRO scale were established, and a theoretical model was developed and a literature review was performed, items from this pool were combined and split, and an initial scale was constructed. After a pilot survey and additional modifications, a pre-questionnaire scale was formed and used in a field investigation. After the application of statistical methods, the item pool was used to create a formal scale. The reliability, validity and feasibility of this formal scale were then assessed. Results: In a clinical investigation, 479 responses were recovered, with an acceptance rate of 95%. a combination of various methods was employed, and the items that were selected by all methods or more than half of the methods were employed in the questionnaire. In these cases, the screening methods were combined with certain features of the item, A total of four domains and 38 items were reserved. The reliability analysis indicated that the PRO scale was relatively reliable. Conclusions: Scientific assessment proved that the proposed scale exhibited good reliability and validity. This scale was readily accepted and could be used to assess the curative effects of medical therapy. However, given the limited scope of this investigation, the capacity for adapting this scale to incorporate other theories could not be determined.

Objectives: Although increased reactive oxygen species (ROS) is caused by stress accelerates collagen degradation, there was no data on the relationship between stress and urinary hydroxyproline (Hyp) and proline (Pro), a good marker of collagen degradation. The purpose of this study was to evaluate the relationship between depression, anxiety, and stress (DAS) and concentrations of urinary Hyp and Pro. Methods: 97 hospital employees aged 20 to 58 were asked to fill out comprehensive self-administrated questionnaires containing information about their medical history, lifestyle, length of the work year, shit-work and DAS. Depression Anxiety Stress Scale (DASS) was applied to evaluate chronic mental disorders. Urine samples were analyzed using High Performance Liquid Chromatography (HPLC) with double derivatization for the assay of hydroxyproline and proline. Results: The mean value of Hyp and Pro concenturation in all subjects was $194.1{\pm}113.4\;{\mu}mol/g$ and $568.2{\pm}310.7\;{\mu}mol/g$. DASS values and urinary Pro concentrations were differentiated by sex (female > male, p < 0.05) and type of job (nurse > others, p < 0.05). In the stepwise multiple linear regressions, urinary Hyp and Pro concentrations were influenced by stress (Adjusted $r^2$ = 0.051) and anxiety and job (Adjusted $r^2$ = 0.199), respectively. Conclusions: We found that stress and anxiety were correlated with urinary Hyp and Pro concentrations. To identifying a definite correlation, further study in large populations will be needed.

This study was aimed to develop an integrative art program that incorporates both emotional and pro-social components for young children (age, 4-5 years). Furthermore, the effectiveness of this integrative program was examined with 39 young children who were divided into the experimental group and the control group of this study. To the experimental group, the integrative art program of interest in this study was provided over 8 weeks. The children of the control group were provided a similar program during the same period. To measure the levels of young children's emotional intelligence and those of their pro-social behavior were assessed by using the emotional intelligence questionnaire and the children's pro-social behavior assessment scale to collect the data. The analysis of covariance by SPSS 18.0 indicated that the young children from the experimental group exhibited higher total scores for emotional intelligence and pro-social behaviors than their counterparts from the control group. The results indicate that the integrative art program of interest in this study improved the young children's emotional intelligence and their pro-social behaviors. Along with main results of this study, implications for research and practice were discussed.

The purpose of this study was to compare professional (Pro) and non-professional (Non-pro) voice users with voice disorders in self-reporting voice evaluation using Korean-Voice Handicap Index (K-VHI) and Korean-Voice Related Quality of Life (K-VRQOL). In addition, those were compared by voice quality and voice disorder type. 94 Pro and 106 Non-pro were asked to fill out the K-VHI and K-VRQOL, perceptually evaluated on GRBAS scales, and divided into three types of voice disorders (functional, organic and neurologic) by an experienced speech-language pathologist and an otolaryngologist. The results showed that the functional (F) and physical (P) scores of K-VHI in Pro group were significantly higher than those in Non-pro group. As the voice quality evaluated by G scale got worse, the scores of all aspects except emotional (E) of K-VHI and social-emotional (SE) of K-VRQOL were higher. All scores of K-VHI and K-VRQOL in neurologic voice disorders were significantly higher than those in functional and organic voice disorders. In conclusion, professional voice users are more sensitive to their functional and physical handicap resulted by their voice problems and that goes double for the patients with severe and neurologic voice disorders.

The purpose of this study was to assess pro-environmental behavior of elementary school students by school year and gender and to investigate the relationships of their emotional affinity toward and intellectual curiosity about life, and experiences about nature and life with the pro-environmental behavior. A total of 436 elementary students participated in the study: 189 3rd grade; 247 6th grade students, and 233 boys; 203 girls. The variables were measured by using a self-report questionnaire with 5-point Likert scale items. The results showed the levels of pro-environmental behavior of the 3rd grade students and the girls were higher than that of the 6th grade and the boys, respectively. Their pro-environmental behavior was significantly related with all measured variables. However, it was found that the direct predictors of their pro-environmental behavior were the intellectual curiosity and the indirect experience, while the emotional affinity and the direct experience did not have a direct impact on the behavior. The predictive power of the intellectual curiosity and the indirect experience for their pro-environmental behavior was higher in 3rd grade than 6th grade. While the indirect experience was a stronger predictor of the boys' pro-environmental behavior than the intellectual curiosity, the curiosity was a stronger predictor of the girls.

Small scale time-course microarray experiments are those which have a small number of time points. They comprise about 80 percent of all time-course microarray experiments conducted up to 2005. Several statistical methods for the small scale time-course microarray experiments have been proposed. In this paper we applied three methods, namely, QR method, maSigPro method and STEM, to a real time-course microarray experiment which had six time points. We compared the performance of these three methods based on a simulation study and concluded that STEM outperformed, in general, in terms of power when the FDR was set to be 5%.
