Purpose: The purpose of this study was to explore self-reported perceived stigma, self-efficacy, and quality of life among psychiatric outpatients Methods: In the present study, researchers analyzed the survey responses of 195 patients recruited in the S hospital psychiatry outpatient clinic. The measurement tools used in this study were the "Devaluation & Discrimination" scale to determine perceptions of stigmatization, general and social efficacy scales to measure self-efficacy, and the "General Well-Being Index" to measure quality of life in psychiatric outpatient. Statistical analysis included means with standard deviation, t-test, ANOVA and Pearson correlation coefficients to identify relationships between the variables. Results: There was a significant difference in self-perceived stigma and quality of life in psychiatric outpatients (r=-.233, p=.001) and a negative correlation between self-efficacy and quality of life (r=-.424, p=.000). Correlation analysis results support the hypothesis that higher self-perceived stigma scores were related to reduced quality of life among patients with schizophrenia (r=-.231, p=.021), while there was a positive correlation between self-perceived stigma scores and self-efficacy scores among patients with bipolar disorder (r=.362, p=.013). Conclusion: The findings suggest that nursing imtervention strategies should include education programs to reduce stigmatization and enhance self-efficacy and quality of life among patients with chronic psychiatric illnesses.

The purpose of this paper is to measure the level of difficulty of fingerprint database based on sample quality. This paper proposes distribution of a sample quality analyzer and a difference of sample quality analyzer to measure the level of difficulty. Experimental results demonstrate that there are stronger correlation between matching performance and level of difficulty based on difference of sample quality than other measure. Especially, level of difficulty based on OQ Block of MPQ co-occurrence matrix shows highest correlation with matching performance, and moreover it can predict the matching performance of unknown databases.

In this paper voice quality of normal speech is qualitatively classified by five components of breathy, creaky, rough, nasal, and thin/thick voice. To determine whether a correlation exists between a subjective measure of voice and an objective measure of voice, each voice is perceptually evaluated using the 1/2/3 scale by speech processing specialists and acoustically analyzed using speech analysis tools such as the Praat, MDVP, and VoiceSauce. The speech parameters include features related to speech source and vocal tract filter. Statistical analysis uses a two-independent-samples non-parametric test. Experimental results show that statistical analysis identified a significant correlation between the speech feature parameters and the components of voice quality.

In this paper, a balanced bitrate control in transcoding process based on video complexity measure for multi-view system which simultaneously shows multiple channels or video contents in single screen, is proposed. In order to consider the total quality of multiple video streams, the proposed algorithm reduces the complexity of multiple video stream and video quality differences at the same time by controlling bitrates of each stream by weighting when they are stitched for single screen. For the measure of complexity and quality differences between video streams, two different data: histogram of macroblock type and bitrate for each stream are used. The experimental result indicates that proposed algorithm decreases fluctuation of quality difference between videos in the multi-view system.

A questionaire survey has been conducted to find out the total quality management practices in Korea. Its initial purpose is to search for some general measure of depth and width of spread of quality management throughout Korean industries, specifically in manufacturing and service sectors. This can be used as a guideline for supporting any activities endeavoring to find appropriate methods to boost quality management in Korea. Also, through comparisional analysis at the macro-level, some characteristics in quality management practices are shown to exist in Korean industries. The analysis is based on perceptions of surveyed people about quality management practices in their companies.

Background: The purpose of this study was to propose a method for developing a measure of hospital-wide all-cause risk-standardized readmissions using administrative claims data in Korea and to discuss further considerations in the refinement and implementation of the readmission measure. Methods: By adapting the methodology of the United States Center for Medicare & Medicaid Services for creating a 30-day readmission measure, we developed a 6-step approach for generating a comparable measure using Korean datasets. Using the 2010 Korean National Health Insurance (NHI) claims data as the development dataset, hierarchical regression models were fitted to calculate a hospital-wide all-cause risk-standardized readmission measure. Six regression models were fitted to calculate the readmission rates of six clinical condition groups, respectively and a single, weighted, overall readmission rate was calculated from the readmission rates of these subgroups. Lastly, the case mix differences among hospitals were risk-adjusted using patient-level comorbidity variables. The model was validated using the 2009 NHI claims data as the validation dataset. Results: The unadjusted, hospital-wide all-cause readmission rate was 13.37%, and the adjusted risk-standardized rate was 10.90%, varying by hospital type. The highest risk-standardized readmission rate was in hospitals (11.43%), followed by general hospitals (9.40%) and tertiary hospitals (7.04%). Conclusion: The newly developed, hospital-wide all-cause readmission measure can be used in quality and performance evaluations of hospitals in Korea. Needed are further methodological refinements of the readmission measures and also strategies to implement the measure as a hospital performance indicator.

Purpose: The purpose of this study was to compare the spiritual well-being and quality of life between hospital and home hospice patients. Methods: A total of 116 patients from 4 hospice hospitals in D city and P city participated in this study from January to April 2012. To measure spiritual well-being, an instrument developed by Paloutzian and Ellison (1982) and revised by Park (2005) was used. To measure quality of life, an instrument developed by Cho (1993) and revised by Sun (2003) was used. The data were analyzed by using descriptive statistics, t-test, $x^2$-test, and ANCOVA. Results: Spiritual well-being and quality of life were higher in home hospice patients than in hospital hospice patients, but they were not statistically significant. Higher education and having religion were significantly related to higher spiritual well-being in both groups. Having religion and pain history for the past one week were significantly related to higher quality of life in both groups. Conclusion: For hospice patients, participation in religious activities needs to be encouraged to improve their spiritual well-being and quality of life. Assessing the hospice patients' pain history with close observation and managing the pain are suggested.
