This study aims to present a new plan to improve Korea-China relations through analysis of major achievements and problems through Korea-China diplomatic relations on the 30th anniversary of Korea-China diplomatic relations. The 1992 Korea-China diplomatic relations were a combination of the end of the Cold War, China's reform and opening policy, and Korea's "Northern Policy" promotion. Since then, Korea-China relations have been evaluated as "a bilateral relationship that has made unprecedented in economic trade and social culture. However, Korea-China relations are still unstable due to lack of political trust, and the complexity of the bilateral relationship is increasing due to various factors, but Korea and China should actively promote the quality of bilateral economic cooperation, strengthen strategic communication and cooperation on the Korean Peninsula, and strengthen trust as good neighbors, friends, and partners.

여등승(DengSheng Yu),장원원(YuanYuan Zhang),임규건(GyooGun Lim) 한국IT서비스학회 2020 한국IT서비스학회지 Vol.19 No.6
Facing the era of intelligence, the demands for changes of e-Government system appears to be rising upon the development of AI, VR, IoT and other new technologies. However, it also comes with the increasing possibility of mobile digital divide among regions, ethnicities and social classes. As the e-Government Service is only available for specific groups, the national government should proactively build an information environment to promote the convenient access and use of e-Government Service comprehensively by all the people. In the light of the sociodemographic characteristics, this study tests whether the difference is statistically significant involving the mobile digital divide between different groups with the analysis of variance, while determining the relationship between the mobile digital divide and the usage intention of e-Government Service through multiple regression analysis. The main findings of this study are as follows. First, there are differences and statistical significance between groups of different ethnicities and regions on accessibility with electronic products and networks. Second, there are obvious differences and statistical significance between groups of different ages, educational levels and ethnicities on the competency and usability of electronic products and networks. Third, the accessibility to electronic products and networks has no effect on the usage intention of e-Government Service, while the competency and usability of electronic products and networks have a strong positive impact on the usage intention of e-Government Service. The author hopes that the research findings of this paper can provide reference suggestions and opinions for bridging the digital divide among regions in China and promoting the popularization of the e-Government Service.

With obesity caused by high fat intake having various adverse effects on people of today's society, the aim of this study is to examine the lowering effect of proportional mate intake on tissue triglyceride and cholesterol levels. Mate, binomial name Ilex paraguariensis, is a species of holly (family Aquifoliaceae), well-known as the source of the mate beverage, which is native to subtropical South America. Five-week-old male Sprague-Dawleys weighing about 200g were used for this experiment. These rats were fed on a diet mixed with 60% fat and instant Mate powder in market circulation. They were divided into four groups, with the control group on a normal diet (n=6), a group on a high fat diet (HFD) (n=6), a group on a high fat diet containing 2% mate powder (MT2) (n=6), and the last group on a high fat diet containing 4% mate powder (MT4) (n=6). The food efficiency ratio made no difference in the MT2 group compared to the HFD group. With the intake of mate powder, serum and tissue triglycerides were decreased in the MT2 group. Especially notable was the fall of triglyceride levels in the liver in the MT2 group by roughly 60%, compared to those of the HFD group. Cholesterol levels in epididymal fat pads were sig-nificantly decreased - by 60% - in the MT4 group compared to those of the HFD group. Also, as a result of DPPH(1,1-Diphenyl-2-picrylhydrazyl) assay, the anti-oxidant activity of Mate powder showed a similar level to that of vitamin E. These findings indicate that triglyceride and cholesterol levels in liver and epididymal fat pads are decreased by the intake of Mate powder. That the dose of Mate powder in the MT4 group had a signifiant effect means that Mate may be capable of interfering in triglyceride and cholesterol levels.
