This study attempted to survey nursing students' motives for choosing nursing as their major, and to examine how such motives affect their satisfaction with their major, campus-life satisfaction, and self-directed learning ability. This study was conducted as a descriptive survey. Data were collected using a self-report questionnaire during the period from the 1st to 15th of April, 2015, and the questionnaires from 195 nursing students were used in the analysis using Fisher's exact test, t-test, one way ANOVA, Mann Whitney test, and ANCOVA. Only 41.5% of the nursing students chose nursing as their major because of their aptitude and interest. The motive for the selection of the major was found to have a significant effect on their satisfaction with the major (p<.001), campus-life satisfaction (p=.008), and self-directed learning ability (p=.001). Middle and high school students should be provided with various types of information on nursing, so that they can have the opportunity to choose nursing based on their aptitude and interest before entering university. Once they start university, nursing students' adjustment to campus-life and learning ability should be enhanced through various extracurricular activity programs in order to stimulate their interest in the major.

From the total methanolic extract of Gardenia jasminoides (Rubiaceae), various antioxidative characteristics were identified in terms of nitrite scavenging ability, 2,2'-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) radical cation inhibition, superoxide dismutase (SOD)-like activity, and elongation effect of lipid peroxidation using Rancimat. After successive partitioning with n-hexane, chloroform, n-butanol, and water, potent nitrite scavenging abilities were shown in the n-butanol fraction and water fraction, and IC 50 values were 183 ppm and 194 ppm, respectively. As for ABTS radical cation inhibition, the chloroform fraction was most potent and its IC 50 was 159 ppm. SOD-like activity was slightly low in all of the fractions. The elongation effect of lipid peroxidation also increased dose-dependently and the antioxidative index (AI) of the total methanolic extract was 2.93 in 1000 ppm, which was more effective than 1.66 of butylated hydroxy anisol in the same concentration. The compounds I and II were isolated through silica gel column chromatography of the active fractions, and identified as geniposide and crocin, respectively, by 1 H-NMR spectral data. The IC 50 values for the nitrite scavenging abilities of geniposide and crocin were 940 ppm and 77 ppm, respectively. In ABTS radical cation inhibition, the IC 50 values of geniposide and crocin were 684 ppm and 549 ppm, respectively. And the EC 50 value for SOD-like activity of crocin was 259 ppm, which was much smaller than 453 ppm by the positive control, chlorogenic acid. The EC 50 value of geniposide could not be identified.
