Objectives: The purpose of this research was to identify the effect of mental health, parenting attitude and attachment on gambling addiction severity among male college students. Methods: Subjects of the research were 292 students recruited from colleges in Seoul, Korea. The questionnaires were composed of CPGI, DASS-21, PBI, ECR-R. The data was statistically analyzed by Chi-square, ANOVA, Scheffe test and Pearson’s correlation. Results: The proportion of moderate-risk gambling and high-risk gambling group was reported 28.1%. There a statistically significant difference between gambling addiction severity groups in Anxiety(F=3.19, p<.05). Statistically significant linear relationship was found between Anxiety and gambling addiction score(r=.15, p<.05). There was statistically significant difference between gambling addiction severity groups in Caring(F=4.74, p<.01). Statistically significant linear relationship was found between Caring and gambling addiction score(r=-2.14, p<.01). There was statistically significant difference between gambling addiction severity groups in Overprotection(F=4.74, p<.01). Statistically significant linear relationship was examined between Overprotection and gambling addiction score(r=.20, p<.01). Significant difference was examined between gambling addiction severity in Attachment Anxiety(F=3.76, p<.05). Attachment Anxiety showed significant linear relationship with gambling addiction score(r=-.17, p<.01). Significant differences were examined between gambling addiction severity in Attachment avoidance (F=3.46, p<.05). Attachment avoidance showed no significant relationship with gambling addiction score(r=-.09, p=.12). Conclusions: This study showed the effect of mental health, parenting attitude and attachment on gambling addiction severity among male college students. Based on the result, it is recommend for nurses to develop intervention to prevent gambling addiction among college students by lowering anxiety, stabilizing attachment through desirable caring attitude from parents.

Purpose: This study aims to test if the age of pregnant women affects the perception, experience, and attitude towards complementary alternative therapy (CAT), by investigating the perception, experience, and attitude of pregnant women under the age of 35, and above 35 (Advanced Maternal Age). The study will 1) find the general characteristics of pregnant women under and over the age of 35 2) compare the perception, behavior, and experience of pregnant women under and over the age of 35, and 3) find the comparison of the perception, behavior, and experience according to the general characteristics of pregnant women under and over the age of 35. Method: The subjects of this study are composed of 44 women under the age of 35 and 44 women above the age of 35, totaling 88 pregnant women visiting midwiferies, obstetrics and gynecology, and baby fairs in Seoul and Gyeong-Gi area. Data for this study was collected from November 28, 2015 to January 6, 2016 for 40 days. The collected data analyzed mean, standard deviation, t test, ANOVA, and chi-square by using SPSS 23.0. Result Results show that there is a significant difference in the perception, attitude, and experience of the two-sample groups in the use of CAT. The question of “what is most necessary when applying CAT in a hospital clinical environment” for the perception criteria came out with the results of t=9.980, p<.05. For the attitude, results showed that the answers of pregnant women under the age of 35 displayed a more positive attitude towards CAT. (t=2.421, p<.05) Lastly, in the experience section, pregnant women under the age of 35 showed more CAT use than the other sample group. Conclusion Results have shown that there is a difference in the perception, behavior, and experience between the two sample groups. Therefore further research on the efficacy and the adverse effects of CAT needs to be done.
Performance of organic photovoltaics using an ytterbium trifluoride n-type buffer layer

<P>Ytterbium trifluoride (YbF3) was used as an n-type cathode buffer layer in conventional poly(3-hexylthiophene):[6,6]-phenyl C61 butyric acid methyl ester (P3HT:PC60BM) bulk heterojunction (BHJ) organic photovoltaic cells. This buffer layer acts as an electron-transport layer and improves the open circuit voltage (V-oc), power conversion efficiency (PCE), and interfacial durability of the device. The physical properties and performance of the device were studied using impedance spectroscopy, photocurrent measurements, ultraviolet photoelectron spectroscopy, and atomic force microscopy. The PCE reached to 3.2% with a 65% fill factor under 1 sun irradiation. The PCE decreased to half of its original value after 120 h at room temperature in air or 24 h at 70 degrees C in air. Comparison with Yb and TiOx cathode buffer layers reveals that YbF3 has superior performance and longevity. These findings suggest that YbF3 has the potential to replace costly device encapsulation.</P>

The purpose of this study is to investigate the academic stress, self efficacy, burn out, social support and college life adaptation of dental hygiene students and their correlations with related factors influencing college life adaptation. A total of 265 students were selected as stratified sampling methods at the universities in which the department of dental hygiene was established nationwide. From September 1, 2015 to October 22, 2015, the self report questionnaire was used. The main variables were college life adaptation, academic stress, self efficacy, burn out, social support, and analyzed using SPSS 21.0. College life adaptation was 5.17 out of 9 points, academic stress was 2.88 points out of 6 points, self efficacy, burn out, and social support were 3.35, 2.60, and 3.54 out of 5, each respectively. Self efficacy and stress due to task and class were significant influences on individual-emotional adaptation in college life adaptation. In the case of college environment adaptation, exhaustion, self efficacy and social support were significant influencing factors. In the case of social adaptation, self efficacy and social support were significant influencing factors. Overall, academic stress and college life adaptation were closely related, and social psychological factors such as burn out, self efficacy and social support were mediated. Therefore, it is suggested that it should be applied to college education in order to increase adaptation of dental hygiene students, to reduce academic stress and burn out, and to develop intervention strategies that can enhance self efficacy and social support.
