본 연구는 대학생의 스마트폰 중독, 셀프리더십과 대학생활적응의 수준을 파악하고 스마트폰 중독, 셀프리더십이 대학생활적응에 미치는 영향을 파악하기 위한 서술적 조사 연구이다. C도와 K도 소재의 대학생 123명을 대상으로 자료를 수집하였고 수집된 자료는 SPSS 25.0 프로그램으로 χ<sup>2</sup>, ANOVA, t-test, 상관관계분석, 다중회귀분석을 실시했다. 연구결과 변수의 평균은 스마트폰 중독 2.47점 셀프리더십 3.66점, 대학생활적응 3.36점이었다. 대학생활적응은 스마트폰 중독(r=-.23, p=.005)과 부적 상관관계를 셀프리더십(r=-.15, p=.031)과는 양적 상관관계를 나타냈다. 대학생활 적응에 미치는 요인으로 셀프리더십(β=.36)은 정적영향으로 나타났지만 스마트폰 중독(β=.03)은 유의하지 않았고 설명력은 51%이었다. 이는 대학생의 대학생활적응을 위한 셀프리더십 강화 및 스마트폰 중독 예방교육에 대한 필요성을 시사하고 대학생활적응을 위한 실천적 함의를 제시하였다는 데 의의가 있다고 할 것이다. The purpose of this study was to identify the levels of cell phone addiction, self-leadership and college adaptation in college students, and further to investigate the influences of students’ levels of cell phone addiction and self-leadership on their college adaptation. Data were collected from 123 students in colleges located in C and K provinces. In order to analyze the data, x<sup>2</sup>, ANOVA, t-test, correlation analysis, and multiple regression were performed by using SPSS. As results, level of their cell phone addiction was 2.4, that of self-leadership and college adaptation was 3.66 and 3.36, respectively. College adaptation showed a negative correlation with cell phone addiction (r=-.23, p=.005) and showed a positive correlation with self-leadership (r=-.15, p=.031). The result of multiple regression showed that self-leadership was a significant predictor of college adaptation, whereas cell phone addiction was not, which explained 51% of total variance. Evidence-based interventions seem to be definitely needed for college students to help their college adaptation by enhancing the self-leadership and preventing the cell phone addiction. Also, further study will be needed to examine other predictors of college adaptation in students.

Purpose: This study was done to examine the effects of Aroma inhalation therapy on test anxiety, stress and serum cortisol in nursing students. Methods: The study design was a pre posttest randomized design with a pre-survey, a 5-day experimental treatment (2012.11.17-21) and a post survey. Participants were 65 students - 31 in the aromatic inhalation group and 34 in the control group. The pre-survey included general demographic characteristics and test anxiety, stress and serum cortisol levels for all students. The experimental group received the aromatic inhalation using aroma oil (mixed Maychang, lavender, rosewood essence - ratio of 3:5:2). Results: The experimental group treated with aromatic inhalation scored significantly lower for test anxiety (t=-2.330 p=.023), physical stress (t=-2.910 p=.005) and psychological stress (t=-3.285 p=.002) compared to the control group. However, there were no differences in serum cortisol levels (t=0.228 p=.820). Conclusion: Results indicate that Aromatic inhalation, using maychang, lavender and rosewood essential oils, contributes significantly to reducing anxiety and stress among nursing students, and can therefore be an effective intervention for anxiety and stress.

본 연구는 간호대학생의 유머감각, 스트레스 및 우울 정도를 파악하고 유머감각, 스트레스 및 우울과의 관계를 규명하기 위한 서술적 상관관계 연구이다. 연구대상자는 K시 소재의 대학교 간호학과에 재학 중인 대학생 227명을 대상으로 설문지로 측정하였으며 수집된 자료는 IBM SPSS Statistics 21.0을 사용하여 통계분석 하였다. 본 연구에서 간호대학생의 유머감각은 $79.63{\pm}8.96$, 생활차원 스트레스는 $2.70{\pm}0.62$, 임상스트레스는 $2.52{\pm}0.67$, 그리고 우울은 $17.05{\pm}8.90$이었다. 간호대학생의 유머감각은 생활스트레스 (r=-.237, p=.001), 임상스트레스 (r=-.182, p=.007), 그리고 우울 (r=-.238, p<.001)에서 모두 유의한 부적 상관관계를 나타냈다. 따라서 이러한 연구결과를 통해 간호 대학생의 유머감각이 스트레스와 우울에 관련이 있는 것으로 나타났다. This study was performed to identify the relationship between sense of humor, stress, and depression in the nursing students. Data were collected from the 20th of June to the 30th of June in 2015 from 227 nursing students in K university. The collected data were analyzed using frequency, percentage, average, standard deviation, independent t-test, one-way ANOVA, kruscal-walis, pearson, spearman, and rank correlation coefficient. The result shows the sense of humor was significantly different between grade (t=-3.814, p <.001) and major satisfaction (${\chi}^2=12.070$, p=.007). The sense of humor was negatively correlated with living stress (r=-.237, p=.001), clinical based stress (r=-.182, p=.007), and with depression (r=-.238, p<.001). This data suggests that sense of humor is relevant in reducing the living stress and clinical based stress. These findings can provide the basis for the development of nursing intervention to increase the ability to cope with stress and depression.
형질전환된 담배 어린 싹의 녹화과정 중 Arabidopsis Cab 프로모터의 활성 차이

Promoters of the chlorophyll a/b binding protein genes, cab1, and cab2, of Arabidopsis thaliana were studied for their functions in differential expression during greening of etiolated shoots. The etiolated shoots were derived from leaves of transgenic tobacco plants with the cab-CAT (chloramphenicol acetyltransferase) translational fusions, and CAT activity was measured to monitor the activities of the cab promoters. Cab1 promoter activity increased rapidly and showed saturation after about 24 hours of greening, but that of cab2 increased with about 2 day-lag period and showed saturation after 6 days, Cab1 promoter activity was more sensitive to levulinic acit (LA) compared with cab2 activity. Cab2 promoter activity was inhibited more sensitively by chloramphenicol (CAP) than by inhibitors of Chl formation. Cab1 promoter activity was, however, inhibited less sensitively by CAP than by LA. The treatment of abscisic acid (ABA) did not block Chl synthesis so significantly as LA treatment did, and cab2 promoter activity was much less sensitive to ABA compared with that of cab1. These results suggest that cab1 expression is strongly related with Chl formation, possibly with δ-aminolevulinic acid accumulation, and cab2 expression is suppressed more by the blockage of translation of Chl a-aporproteins than by the blockage of Chl a accumulation.
