As the number of Chinese students in Korea has significantly increased, the problems of students' life and academic achievement has appeared obviously. Utilizing an analysis on the relationship between the life satisfaction of Chinese students in Korea and the degree of internet addiction, the purposes of this research are to improve the quality of Chinese students' life and to contribute to the growth of Chinese students in Korea. A questionnaire-type survey was conducted on 350 Chinese college students in Daegu. The results of this study are as follows: First, the used time on internet games, chat and on-line TV differs from gender, the duration of internet games and their academic performance. Second, there are significant differences by gender, Korean ability, and academic performance in the life satisfaction of Chinese students in Korea. Third, Chinese college students in Korea are more addicted in the internet than Korean or Chinese college students at their own country. Fourth, the longer playing online game, the longer watching online TV, the less communicating with the Koreans, and the less satisfying with non -study related activities, the more Chinese college students of studying in Korea are addicted in the internet.

Korean learners of Chinese have diniculties in pronouncing Chinese tones which distinguish the meaning of words, because there are not such tones in Korean language. It makes Koreans hard to acquire Chinese. In this paper, I present the followings: First, I examine the characteristics of the tones pronounced by Korean speakers, exploiting the method of modern experimental phonetics. Second, I present the pedagogy of Chinese tones, considering the typical errors shown by the experiments on Korean speakers. The Pedagogy Presented in this Paper, which is based on the results of experiments, is not perfect. However, I expect this paper to serve as instrumental tools to help Korean speakers to improve their command of Chinese.

본 연구는 문헌 연구를 통하여 국제 교류 시각에서 조선시대의 한문교육 시행의 의미에 대해 살펴보았다. 구체적으로 역사적 자료들을 정리하면서 조선시대 한문교육의 시행 기관, 교육내용 및 주요 특징, 당시 한반도에 미치는 영향 및 오늘날 중국의 중국어 국제교육에 주는 시사점을 살펴봤다. 연구결과, 조선시대의 한문 교육 기관으로 주로 사역원과 승문원에서 한문 교육의 역할을 하고 있었다. 시행한 한문 교육의 내용은 주로 중국어 구어 교재의 개발, 운서와 같은 도구 서적의 간행, 사전 등에 대한 편찬 및 중국어 통역원 양성 등으로 나타났다. 중국 운서에 대한 깊은 연구를 통하여 한반도는 1433년 자기 민족의 문자인 한글이 창제되어 한자의 의지에서 벗어나게 되었다. 한글의 발명은 한반도의 정치, 경제 및 문화 분야의 발전을 크게 발전시켰다. 또한 조선시대의 한문교육은 오늘날 중국의 중국어 국제교육에 좋은 경험을 제공해 주었다.

Recently, there is the huge interest to promote the export of Korean agro-food to Chinese market. However, small number of papers analyze the Chinese consumer to find the strategy for launching Korean agro-food in Chinese market. The purpose of this paper is to analyze Chinese consumer for Korean agro-food in Chine. Survey analysis was conducted in 4 big city (Beijing, Shanghai, Guangzhou, and Tsingtao) for this research. The results of studies present a few findings: First, many Chinese consumers prefer Korean agro-food. Second, among big cities, Beijing shows the highest level of preference for Korean agro-food, Third, Chinese consumers can pay higher price for Korean agro-food, Fourth, Chinese consumer usually buy small amount of agro-food. Fifth, the image of Korea is also important to promote the exportation of Korean agro-food to Chinese market.

초 중등학교 수학 용어의 대부분은 한자말이거나 한자말이 섞여 있다. 한자말 용어의 각 한자를 한자사전을 통해 확인하고, 한자의 뜻으로 한자말 용어를 이해할 수 있는지를 비판적으로 검토한다. 이를 통해 한자말이거나 한자말이 섞여 있는 수학 용어들을 한자의 뜻이 그것이 들어있는 용어의 개념을 이해하는 데 도움이 되는 경우와 도움이 안되는 경우 및 한자의 뜻이 오히려 잘못된 개념을 얻게 하는 경우로 나누어 파악한다.

This study is concerned with the names of is sa mai(잇사매) and ham sa mai(함사매). Origins and meanings of these terms were traced and examined. Some significant findings can be summarized as follows : Korean word is sa mai(잇사매) was a compound word. Korean character is (잇) is derived from Chinese character i, and sa mai(사매) in Korean means sleeves 神 in Chinese character. The character ham in Ham sa mai(함사매) is its origin in Chinese : Korean character ham was Korean pronounciation of the Chinese character, han. ham sa mai is a compound word of ham(함) (Korean), (han ) (Chinese) and sa mai(사매) sleeves(Korean). Thus, first characters of is(잇) in is sa mai(잇사매) and ham(함) in ham sa mai(함사매) are originated from Chinese, where as the word sa mai in the end of is sa mai and ham sa mai is pure Korean. Both character i and ham(han, Chinese) in Chinese means a jaw. Thus, both is sa mai(잇사매) and ham sa mai(함사매) means “jawed sleeves”. That is long and wide round sleeves with narraw wrists.

Background: Notoginsenoside Ft1 is a promising potential candidate for cardiovascular and cancer disease therapy owing to its positive pharmacological activities. However, the yield of Ft1 is ultralow utilizing reported methods. Herein, an acid hydrolyzing strategy was implemented in the acquirement of rare notoginsenoside Ft1. Methods: Chemical profiles were identified by ultraperformance liquid chromatography coupled with quadruple-time-of-flight and electrospray ionization mass spectrometry (UPLC-Q/TOF-ESI-MS). The acid hydrolyzing dynamic changes of chemical compositions and the possible transformation pathways of saponins were monitored by ultrahigh-performance LC coupled with tandem MS (UHPLC-MS/ MS). Results and conclusion: Notoginsenoside Ft1 was epimerized from notoginsenoside ST4, which was generated through cleaving the carbohydrate side chains at C-20 of notoginsenosides Fa and Fc, and vinaginsenoside R7, and further converted to other compounds via hydroxylation at C-25 or hydrolysis of the carbohydrate side chains at C-3 under the acid conditions. High temperature contributed to the hydroxylation reaction at C-25 and 25% acetic acid concentration was conducive to the preparation of notoginsenoside Ft1. C-20 epimers of notoginsenoside Ft1 and ST4 were successfully separated utilizing solvent method of acetic acid solution. The theoretical preparation yield rate of notoginsenoside Ft1 was about 1.8%, which would be beneficial to further study on its bioactivities and clinical application.

The purpose of this study is to identify stresses and adjustment elements of Chinese students in Korea. The data analysis was conducted by qualitative method based on interviews with sixteen Chinese students as a focus group by the help of two interpreters. The results were as follows: first, stresses of Chinese students were from 'cultural difference', 'language', and 'financial', 'educational' and 'psychological stress', and 'university culture in Korea'. Those categories were divided into several sub categories. Second, ten helpful elements Chinese students could adapt themselves to Korean university life were such as 'Help of Korean professor and friends', 'Chinese friends' help', 'English-oriented lecture', 'Cultural affinity to Korea', 'Fluency in Korean language', 'Integration to Korean culture', 'Pride in Chinese culture', 'Individual effort', 'Satisfaction with educational environment', 'Perception of self-growth'.

Amino-acid neurotransmitter system dysfunction plays a major role in the pathophysiology of depression. Several studies have demonstrated the potential of amino acids as a source of neuro-specific biomarkers could be used in future diagnosis of depression. Only partial amino acids such as glycine and asparagine were determined from certain parts of rats' brain included hippocampi and cerebral cortex in previous studies. However, according to systematic biology, amino acids in different area of brain are interacted and interrelated. Hence, the determination of 34 amino acids through entire rats' brain was conducted in this study in order to demonstrate more possibilities for biomarkers of depression by discovering other potential amino acids in more areas of rats' brain. As a result, 4 amino acids (L-aspartic acid, L-glutamine, taurine and ${\gamma}$-amino-n-butyric acid) among 34 were typically identified as potentially primary biomarkers of depression by data statistics. Meanwhile, an antidepressant called Fluoxetine was employed to verify other potential amino acids which were not identified by data statistics. Eventually, we found L-${\alpha}$-amino-adipic acid could also become a new potentially secondary biomarker of depression after drug validation. In conclusion, we suggested that L-aspartic acid, L-glutamine, taurine, ${\gamma}$-amino-n-butyric acid and L-${\alpha}$-amino-adipic acid might become potential biomarkers for future diagnosis of depression and development of antidepressant.
