  • The purpose of this study is to develop a mass preparation method of (+)-decursinol from Angelica gigas roots. Recently; it has been shown that (+)-decursin, (+)-decursinol angelate and its analogues, isolated from Angelica gigas roots, exhibit various biological activities such as antitumor, antibacterial and neuroprotective activities. The contents of these compounds, ester form of (+)-decursinol, is very high in the Angelica gigas roots, whereas the content of (+)-decursinol itself is very low Therefore, (+)-decursinol which can be used as starting material to synthesize various its analogues was easily prepared from decursin analogues in the Angelica gigas roots. In order to achieve such aim, the Ether-Fr. of the ethanol exact of Angelica gigas roots was hydrolysed with various alkalis and solvents. As a result, the order of (+)-decursinol preparation was 1) NaOH, KOH, 2) $K_2CO_3$, and 3) $NaHCO_3$ as alkali. Also, the yield of (+)-decursinol was higher in diethyl ether than any other solvent conditions. From 1 kg of dried Angelica gigas roots, we could obtain 27.4 g of (+)-decursinol as a pure white solid.

  • This study analyzed the effect of career preparation behavior of female college graduates on their job satisfaction. The results of this study are as follows: First, the relationship between job satisfaction and career preparation behavior and a regression analysis of job satisfaction were all examined. This study used the original data from the Korea Employment Information Service for '2012 College Graduates' Occupation Route Survey'. The subjects of this study were 1,569 women in the science and engineering fields (649 engineering graduates, and 920 science graduates). The data was analyzed by frequency analysis, independent sample t tests, correlation analysis, and hierarchical multiple regression analysis using SPSS WIN 19.0. As a result, women with 4 years of college have higher job stability and job satisfaction than college students, but the reasons for major selection, university type, college location, and department. The results of this study are as follows. First, the effect of the variables on career satisfaction and job satisfaction was not statistically significant. This suggests that the type of college does not have a significant effect on job satisfaction if the university systematically prepares people for a career and the university suits a person's aptitude.

  • This study investigated how the big five personality traits among clinical laboratory science students affect their levels of academic satisfaction and verified the mediating effect of career preparation in the context of these personality traits influencing academic satisfaction. A total of 300 college students attending a 3-year college in Daegu were surveyed, and 260 were analyzed. SPSS 22.0 was used for statistical analysis while Baron and Kenny (1986)'s three step method was carried out for basic analysis, correlation analysis, and verification of the mediating effect of the collected data. Results of this study are as follows. Firstly, the correlation analysis between variables shows that extroversion, openness, agreeableness, and conscientiousness among the big five personality traits had significant positive relationships with academic satisfaction and career preparation while neuroticism showed a significant negative relation with academic satisfaction and no significant relation with career preparation. Secondly, the mediating effect verification found that extroversion, openness, agreeableness, and conscientiousness, but not neuroticism, had significant mediating effects; extroversion especially was confirmed to have a complete mediating effect. Thus, methods are needed to improve academic satisfaction and career preparation in college.
