This study was conducted to investigate the relationship among self-efficacy, disaster preparedness and self-leadership of university students. Data were collected through questionnaires from 141 students and analyzed using descriptive statistics, t-test, ANOVA, Scheffe's test, and Pearson's correlation coefficients with the SPSS/WIN 19.0 program. The participant's scores for self-efficacy and self-leadership were 3.51 and 3.53, respectively. Disaster preparedness was significantly correlated with self-efficacy and self-leadership of university students, while self-efficacy was significantly correlated with self-leadership. The results of this study indicate that self-efficacy and self-leadership should be carefully considered when developing an intervention program to improve disaster preparedness among university students.

This study conducted non-equality control post-design similar experimental study in order to investigate the effect of self-directed practice through self-reflection by using videos on the basic nursing performance ability, confidence in performance, learning self-efficacy, and practice satisfaction. The experimental group was 57 students and the control group was 56 students in the Department of Nursing in G region. The data was collected from April 1, 2017 to June 14, 2017. For analyzing data, the SPSS 22.0 program was used and the homogeneity test was analyzed with ${\chi}^2$ test, t-test, and Fisher's exact test. Also, independent-test was used. According to the result, all of the experimental groups including the basic nursing performance ability, confidence in performance, learning self-efficacy(t=15.304, p<.001), and practice satisfaction(t=15.304, p<.001) were improved and showed significant differences compared to the control group. As a result, it is predicted that the practice method has a positive effect on participating in self-study and it contributes to active participation by increasing learning motivation of learners. Thus, it is suggested to be applied to various practical training to improve basic nursing skills.

A test tool for self-leveling and flowing characters of coating materials used to semiconductors and electronic parts, especially for protection of LCD and PDP connectors, was designed, and the test tool was evaluated using polymeric siloxane coating materials which have various viscosities. The test results showed that the designed test tool was effective to measure self-leveling and flowing properties of coating materials. Therefore, considering that the viscosity is not directly correlated with self-leveling and flowing properties, we believe that this test tool will be a very useful tool for measurement instead of classical method using viscosities of coating materials. Particularly, the measurement of self-leveling and flowing properties using the test tool would be expected to be used in the area of selecting suitable protective coating materials for LCD (Liquid Crystal Display), PDP (Plasma Display Panel) and semiconductor connection parts.

Purpose: This study was conducted to investigate factors affecting the dementia screening test based on the health belief model. Methods: The survey was conducted with structured questionnaires assessing the knowledge of dementia, health beliefs, self-efficacy and cue to action for dementia screening. Study participants were 156 older adults and data from 121 respondents were analyzed. Descriptive statistics, frequency percentage, chi-squared (${\chi}^2$) test, t-test and logistic regression analysis were conducted using SPSS version 23.0. Results: Factors influencing the dementia screening test were found to be gender, self-efficacy on dementia screening, and the presence of family or friends who underwent dementia screening. Older adults who were female (OR=4.92, p=.003), showed an increasing average score of self-efficacy for dementia screening (OR=2.85, p=.002), and had family members or friends who underwent dementia screening (OR=4.60, p=.003) were more likely to receive dementia screening. Conclusion: This study showed that education and programs enhancing self-efficacy associated with the dementia screening test, as well as utilizing the network of family or friends are necessary to increase the rate of dementia screening.

This paper presents a programmable RF BIST (Built-in Self-Test) circuit for low noise amplifiers. We have developed a new on-chip RF BIST circuit that measures RF parameters of low noise amplifier (LNA) using only DC measurements. The BIST circuit contains test amplifier with programmable capacitor banks and RF peak detectors. The test circuit utilizes output DC voltage measurements and these measured values are translated into the LNA specifications such as input impedance and gain using the mathematical equations. Our on-chip BIST can be self programmed for 1.8GHz, 2.4GHz and 5.25GHz LNA for GSM, Bluetooth and IEEE802.11g standards.

The primary purpose of this study was to investigate the relation between paternal self-esteem, child-rearing behaviors and child's self-esteem. The secondary purpose was to examine whether there were significant relational differences according to child's sex. 272 dyads consisting of fifth and sixth grade children in elementary school and their measured by the Self-Esteem Inventory (for children), the Self-Esteem Scale (for fathers), and the Iowa Parent Behavior Inventory: Father form. Pearson's r., F-test, and Ducan's multiple range test were used for data analysis. Paternal self-esteem was significantly associated with 'parental involvement', 'reasoning guidance', and 'intimacy'. Paternal self-esteem was positively correlated with girl's self-esteem. Child's self-esteem was positively related to 'parental involvement', 'limit setting', 'responsiveness', 'reasoning guidance' and 'intimacy'. In sex differences, only boy's self-esteem wasn't related to paternal 'limit setting'. Boys' self-esteem was strongly related to 'parental involvement', and girls' self-esteem was strongly related to 'reasoning guidance'.

Purpose: The purpose of this study was to identify the effect of self efficacy and self leadership on stress in adolescents. Methods: Data were collected from 722 adolescents and analyzed using descriptive statistics, t-test, ANOVA, Scheffe's test, Pearson correlation coefficients and stepwise multiple regression with the SPSS 20.0 program. Results: Stress differed according to gender, grade, economic level. Self efficacy and self leadership had a significant negative correlation with stress. Stepwise multiple regression analysis showed self efficacy(general self efficacy), self leadership(cognitive strategies), gender(female), grade(high school) explained 32.5% of the total variance in stress. The findings indicate that self efficacy and self leadership had an influence on stress. Conclusions: The results of this study offer basic data for the development of intervention programs to prevent adolescents stress.

The solidification crack susceptifility of aluminum alloy weld metal have been evaluated by means of the slef restraint and external restraint cracking test. It has been observed expermently as follows : (1) The manganese is beneficial to decrease the solidification cracking susceptibility. (2) Weld metal containing zirconium is less sensitive to the solidification cracking than the weld metal containing chromium does. (3) The self restraint test method shows the same tendency in results as the external restraint test does.

The purpose of this study was to investigate the effects of mindfulness meditation programs based on stress management on the perceived stress, self-control, self-esteem and satisfaction with life scale in nursing college students. A quasi-experimental study with a non-equivalent control group pretest-posttest design was used. Participants consisted of an experimental group(n=18) and a control group(n=22). The experimental group received the mindfulness meditation program for 60 minutes a week for 13 sessions. Data were analyzed using descriptive statistics, ${\chi}^2-test$, Fisher's exact test, t-test, Mann-Whitney U test. The results showed there were significant decrease for perceived stress(t=-9.43, p=.025) and improved self-esteem(t=1.98, p=.038) in the experimental compared to group control group. These findings indicate that mindfulness meditation programs is effective to psychological well-being in nursing college students. Therefore this program needs to be considered as a nursing curriculum for students.
