This study was designed to identify the degree of perceived self-efficacy and self-esteem in non - insulin dependent diabetes mellitus. The 278 Diabetic patients participating in this study were selected from a diabetic clinic. The period of data collection was September 2 to September 10, 1996. Collected data were analyzed by means of Frequency, Mean, SD, t - test, Pearson correlation, ANOVA using SPSS/PC+. The result are summarized as follows: 1. The mean score of perceived self-efficacy were 3.52 in total, 3.91 for medication, 3.40 for exercise, 3.60 for diet control, 3.18 for glucose test, 3.53 for general management. And the mean score of self-esteem were 3.51 2. Perceived self-efficacy and self-esteem had statistically significant positive correlations (r=.3125, p=.001). 3. The results of testing for the degree of perceived self -efficacy, according to the subject's demographic variables, showed that there were significant differences in sex (t=4.14, p<0.001), the level of education(t=6.24, p<0.01) and diabetic education(t=3.25, p<0.05). These results suggest that perceived self-efficacy and self-esteem is an important variable in the compliance of diabetic patients.

Purpose: Self-care behavior is a key dimension of healthcare quality among elderlys with diabetes mellitus. The purpose of this study was to identify factors associated with self-care behaviors related to insulin therapy among elders with diabetes mellitus. Methods: The research was a cross-sectional, descriptive design using questionnaires. The participants were 147 older adult patients with diabetes mellitus receiving insulin therapy. Data were analyzed using descriptive statistics, t-test, ANOVA and multiple regression with SPSS statistics 19.0 program. Results: Participants' self-care behaviors related to insulin therapy were not adequate. Stepwise multiple regression analysis for self-care behaviors related to insulin therapy revealed that the most powerful predictor was self-efficacy. Self-efficacy, family support and frequency of blood sugar test explained 54.4% of the variance in self-care behaviors related to insulin therapy. Conclusion: The results indicate a need to promote self-efficacy, family support and frequency of blood sugar testing with these participants. In addition, strategies to improve self-care behaviors among elderly patients should be considered by health professionals, family members and the elderly patients themselves.

The design and development procedures of SF6 gas circuit breakers are still largely based on trial and error through testing although the development costs go higher every year. The computation cannot cover the testing satisfactorily because all the real processes arc not taken into account. But the knowledge of the arc behavior and the prediction of thermal plasmas inside SF6 interrupters by numerical simulations are more useful than those by experiments due to the difficulties to obtain physical quantities experimentally and the reduction of computational costs in recent years. In this paper, in order to get further information into the interruption process of a SF6 self-blast interrupter, which is based on the combination of thermal expansion and arc rotation, gas flow simulations with a CFD-arc modeling are performed during the whole switching process such as high-current period, pre-current zero period, and current-zero period. Through the complete work, the temperature of residual arcs as well as the breakdown index after current zero should be a good criterion to predict the dielectric capability of interrupters.

Defects positioning of underground gas pipelines using MFL(magnetic flux leakage) inspection which is one of non-destructive evaluation techniques is proposed in this paper. MFL signals acquired from MFL PIG(pipeline inspection gauge) have nonlinearity and distortion caused by various external disturbances. SQI(self quotient image), a compensation technique for nonlinearity and distortion of MFL signal, is used to correct positioning of pipeline defects. Through the experiments using artificial defects carved in the KOGAS pipeline simulation facility, it is found that the performance of proposed defect detection is greatly improved compared to that of the conventional DCT(discrete cosine transform) coefficients based detection.

Oscillation-based testing of analog-to-digital converters represents a viable option for low-cost built-in self-testing in mixed-signal design. While numerous papers have addressed implementation issues, little attention has been paid to the measurement accuracy. In this letter, we highlight an inherent measurement uncertainty which has to be considered when deriving the parameters from the oscillation frequency.

Purpose: This study was done to investigate the degree of self-care, family support and depression, and relationship among these variables for elder with diabetes mellitus. Method: Participants were 202 diabetic patients, 65 years or over, living in Seoul, Korea. Data were collected using the self-care tool for diabetic patients by Kim (1996), the family support tool for diabetic patients by Park (1984), and Korea's BDI scale by Lee (1995). Results: Of the patients, 43.1% showed HbAlc levels than higher 7%. The highest mean score was for self-care for medication compliance, and the lowest for blood glucose testing compliance. Factors affecting self-care were employment, education, HbAlc level, diabetic self-care education and complications. Factors affecting family support were living with family, diabetic self-care education, hospitalization and complications. Factors affecting depression were gender, living with family and complications. All of these factors were significant. Patients experiencing depression were 16.8% of patients. There was a significant positive correlation between self-care and family support, and significant negative correlations between self-care and depression, and family support and depression. Conclusion: For more effective management of diabetes mellitus in elders, improvement in self-care compliance, and family support are needed.

We proposes a new approach for testing the self visual-acuity by using the KS standard optotype. The proposed system provides their hand-gesture recognition method for the convenient response of subjects in the visual acuity measurement. Also, this system can measure a visual-acuity that excludes the examiner's subjective judgement or the subject's memorized guess, because of presenting a random optotype automatically by computer without a examiner. Especially, Our system guarantees the reliability by using the KS standard optotype and its presentation(KS P ISO 8596), which is defined by the Korea Standards Association in 2006. And the database management function of our system can provide the visual-acuity data to the EMR client easily. As a result, Our system shows the 98% consistency in the limit of the ${\pm}1$ visual-acuity level error by comparing the visual-acuity chart test.

This study was tried to explore the mediating effect of workplace learning and self-efficacy on the relationship between technostress and job satisfaction in convalescent hospital nurses. Data were collected from 149 nurses working at one of 10 convalescent hospitals located in Korea's D region and between July 20 and August 12, 2019 and analyzed using SPSS 24.0. The mediating effects of workplace learning and self-efficacy in the relationship between technostress and job satisfaction were investigated by conducting hierarchical regression analysis and testing for significance based on bootstrapping p values. We found that workplace learning had a complete mediating effect, and self-efficacy a partial mediating effect, in the relationship between technostress and job satisfaction in convalescent hospital nurses. Exploring diverse factors and environmental features affecting job satisfaction in convalescent hospital nurses is highly relevant to clinicians, especially given the gradually increasing number of convalescent hospitals, changes during the era of technology fusion, and the strategic demands arising from an aging society.
