This study was to identify the factors influencing college life adjustment and sub-scales of nursing students. Self- report questionnaire surveys were conducted toward 282 freshman nursing students to measure college life adjustment, psychological well-being, emotional intelligence, and self-efficacy. Data were collected from September 22 through October 7, 2016. This study was analyzed using SPSS Win 18.0. The average mean of college life adjustment was 3.36 and academic activity was the highest, followed by individual psychology, social experience, Interpersonal relationship, and career preparation. A correlation of psychological well-being, emotional intelligence, self-efficacy, college life adjustment and sub-scales showed positive correlation. The strongest predictor of college life adjustment was a self-efficacy. And sub-scales, the strongest predictor of academic activity was academic achievement, career preparation was self-efficacy, individual psychology and social experience was emotional intelligence, and Interpersonal relationship was psychological well-being. An intervention program which includes these significant variables of subjects is essential to improve of college life adjustment.

The purpose of this study is to find out whether critical thinking education improves critical thinking disposition of nursing college students. The participants were 173 second graders. The education was conducted three times, two hours each, for a total of six hours of intensive critical thinking education and continuous education during Nursing Process class. The survey was conducted in the first week and 14th week of the course. The collected data was analyzed with IBM SPSS 21.0. Findings: The results showed that the average rating of critical thinking before and after education was raised(3.65±0.41→3.83±0.46, t=6.796, p<.001). Among the sub-items, creativity, which had the lowest score before education, has been raised the most(3.13±0.78→3.43±0.86, t = 5.842, p<.001). The effectiveness of critical thinking education has been confirmed. But it is a lack of evidence on the relevance of the details. It is suggested that repeated research is needed to ensure the quality of education, develop teaching methods, and develop tools for verifying effectiveness.

The purpose of this study was to examine the ethical dilemma of dental hygienists and the level of empowerment among them in an attempt to provide some information on how to alleviate the ethical dilemma of dental hygienists to boost their empowerment. The findings of the study were as follows: The dental hygienists got a mean of 1.58 out of possible four points in ethical dilemma. Among the subfactors of ethical dilemma, they scored highest in ethical dilemma about dental hygienists and profession (1.79), followed by dental hygienists and patients (1.53), life reverence and respect for human rights (1.51) and dental hygienists and cooperators (1.49). As for the general characteristics of the dental hygienists, those who were better educated and who intended to temporarily work just until marriage fell into a more ethical dilemma. The dental hygienists got a mean of 3.05 out of possible five points in empowerment. Among the subfactors of it, they scored highest in support structure (3.52), opportunity structure (3.18), information structure (3.08) and resources structure (3.04). There were significant gaps among the dental hygienists in empowerment according to their attitude toward the dental hygienist job as a profession. There was a significant negative correlation between ethical dilemma and empowerment. Regarding influential factors for the ethical dilemma of the dental hygienists, marital status and empowerment were identified as significantly influential factors, and empowerment had a significant relationship to age, academic credential and ethical dilemma. Given the findings of the study, the development of various intervention programs and empowerment-boosting strategies is required to relieve dental hygienists of ethical dilemma.

The present study was undertaken to classify and describe the spring naturalized plant communities in old-Andong city by the methodology of the ZM school of phytosociology. As a result, the vegetation was classified into the six communities and two subcommunities: A. Bromus tectorum community A-a. Bromus japonicus subcommunity, A-b. Melica onoei subcommunity; B. Poa pratensis community; C. Rumex crispus community; D. Oenothera lamarckiana community; E. Ambrosia artemisiifolia var. eiatior community; F. Rumex conglomeratus community. The total taxa of the naturalized plant communities consisted of 31 families, 86 genera, 114 species and 13 varieties. Of which the taxa of the naturalized plant species consisted of 8 families, 21 genera, 25 species and 1 variety. The result of Bray-Curtis ordination revealed that the plots suveyed were arranged according largely to the vegetation units of' the communities. Also the interspecific affinity was examined by an analysis of interspecific association and the main component species in the communities were divided into two groups. The naturalized rate was higher in the communitise affected by strong human impacts, while was lower in the communities affected relatively less by human impacts. On the other hand the seasonal changes of the communities and the naturalized rate between the spring and the autumn were investigated. Many naturalized communities present in Spring were replaced by the other native ruderal communitues in the Autumn. The naturalized rate based on the dominance was largely decreased over from the spring to the Autumn.

Purpose: This study is aimed to confirm nurse's attitudes and to investigate the factor analysis on organ donation in brain dead donors. Methods: This survey were collected from 198 nurses in three university hospitals and four general hospitals in B city with questionnaires developed by the author. The consent for this research was obtained from nursing managers, head nurses, and staff nurses after explaining the purpose of this research. Results: In questionnaires, 45 items about attitudes were included and positive and negative attitude were analyzed. The contents of factors are 'legal permission of brain death', 'one's will of organ donation at the brain death', 'need for educational program about brain dead during college curriculum', 'organ donation is good presents for others', 'connection with professional institutes', 'necessity of brain death', 'convenient to control of brain death' and 'the goods for organ transplantation in brain dead donors' as positive attitudes. Meanwhile, 'contrast to certain religion and dignity to life', 'negative dangers on brain dead permission', 'unbelief to the medical teams', 'burdens to ask organ donation to brain deads/families' and 'economical compensation' are factors as negative attitudes about organ donation in brain dead. The total mean point score of positive attitudes about organ donation in brain dead donors was $3.753{\pm}3.398$. The total mean point score of negative attitudes about organ donation in brain dead donors was $2.915{\pm}0.472$. Conclusion: The results of this study may be of help for the nurses who concern organ sharing and make effective interventions and educations to facilitate the decision making process for organ donation in brain dead donors or families.

This study was conducted to investigate the relationships among self-efficacy, family support, and self-care performance of gastric cancer surgery patients. The study was conducted from 11 October to 15 November 2013. Data were collected by self-report questionnaires from 121 patients who were diagnosed with stomach cancer and had undergone surgery at D university hospital in B city and were in follow-up care for 3 months to 5 years after surgery. Data were analyzed using SPSS/PC WIN 18.0 to obtain the percentage, average, mean rating, and standard deviation. In addition, t-test, ANOVA, Scheffe's test, Pearson's correlation and stepwise multiple regression were conducted. The degree of self-care performance in research targets showed significant differences by sex (t=-2.25, ｐ=0.027), religion (F=3.67, ｐ=0.028) and profession (F=4.17, ｐ=0.008). Self-care performance was positively correlated (r=0.60, ｐ<0.001) with the degree of specific self-efficacy. There was a significant difference in self-care performance by specific self-efficacy, religion and gender. The total explanatory power was 37.9% and the explanatory power of the degree of specific self-efficacy (${\beta}=0.53$) was greater than that of other factors. Therefore, it is necessary to provide interventions that improve specific self-efficacy to help patients with gastric cancer patients conduct self-care performance, and practical measures should be made with respect to religion and gender.
