Objectives: The purpose of this study was to investigate emotional intelligence and organizational commitment according to the coaching types of clinical nurses. Methods: The subject were 195 clinical nurses. Data collected from September 22 to October 10, 2014. Collected data were analyzed with χ2 test, Fisher’s exact test, Kruskal-Wallis test, ANCOVA and Pearson’s Correlation Coefficient analysis. Results: As for the distribution of coaching types among the participants, the friendly type consisted of 116 participants (59.5%), a social type consisted of 31 participants (15.9%), commanding type consisted of 25 participants (12.8%) and the analytical type consisted of 23 participants (11.8%). Differences in general characteristics according to coaching types were statistically significant in age, marital status, job experience and current job position. There were statistically significant difference in emotional intelligence, regulation of emotion, use of emotion, emotional commitment and normative commitment according to coaching type. There were significant correlation between emotional intelligence and organizational commitment of coaching types excluding the commanding type. Conclusions: These findings suggest that in order to higher levels of emotional intelligence and organizational commitment of clinical nurses, it is necessary to understand the coaching type of individual clinical nurses and to develop and implement systematic programs for efficient personnel management to attain.

Objectives: The purpose of this study was to examine affecting factors on problematic drinking of college students. Methods: The subjects were 258 college students. Data collected from November 28 through December 9, 2016. Collected data were analyzed with Independent t-test, One-way ANOVA, Pearson`s correlation and multiple regression analysis. Results: Problematic drinking based on general characteristics showed statistically significant difference in gender, age, grade, resident type, major GPA, having smoke and drinking cost. The factors affecting problematic drinking were as follows: high drinking costs, low major GPA, smoker, drinking refusal self-efficacy and drinking motivation. The explanatory power of theses factors was 54.3%. Conclusions: This findings suggest that in order to reduce the problematic drinking of college students, it is necessary to develop and apply a reducing drinking program considering individual factors, cognitive factors, and socio-cultural factors and it should be approached from a diverse and comprehensive viewpoint including smoking cessation education.

This study aimed to investigate antioxidant activities from 11 forest plants, and determine their total phenolics, flavonoids and proantocyanidins contents. In addition, the antioxidant activities were correlated with antioxidant compounds. Among the samples, Cornus officinalis, Castanea crenata, Lindera erythrocarpa, Carpinus laxiflora and Pourthiaea villosa showed significantly higher 2,2-diphenyl-1-picrylhydrazyl (DPPH) ($IC_{50}=21.12{\sim}28.93{\mu}g/mL$) and 2,2'-azino-bis(3-ethylbenzothia zoline-6-sulfonic acid) (ABTS) ($IC_{50}=28.18{\sim}52.55{\mu}g/mL$) radical scavenging ability with reducing power ($IC_{50}=59.91{\sim}93.64{\mu}g/mL$) than other plants; and C. crenata, L. erythrocarpa and Rubus coreanus showed strong nitric oxide (NO) inhibition activity (${\geq}60%$). In addition, L. erythrocarpa, C. laxiflora and P. villosa showed higher oxygen radical absorbance capacity (ORAC) values (${\geq}1,100{\mu}M$ TE/g sample) than other samples. High total phenolic contents were observed in C. crenata (429.11 mg GAE/g), L. erythrocarpa (437.11 mg GAE/g), C. laxiflora (408.67 mg GAE/g) and P. villosa (404.11 mg GAE/g). The DPPH and ABTS radical scavenging activity with reducing power were significantly correlated with total phenolic contents ($R^2=0.71{\sim}0.79$), but total phenolic contents were not correlated with NO inhibition and ORAC ($R^2=0.35{\sim}0.43$). Therefore, these results suggested that C. officinalis, C. crenata, L. erythrocarpa, C. laxiflora and P. villosa are potential natural antioxidative candidate ingredients.
