  • Background: Panax quinquefolius and Panax notoginseng are widely used and well known for their pharmacological effects. As main pharmacological components, saponins have different distribution patterns in the root tissues of Panax plants. Methods: In this study, the representative ginsenosides were detected and quantified by desorption electrospray ionization mass spectrometry and high-performance liquid chromatography analysis to demonstrate saponin distribution in the root tissues of P. quinquefolius and P. notoginseng, and saponin metabolite profiles were analyzed by metabolomes to obtain the biomarkers of different root tissues. Finally, the transcriptome analysis was performed to demonstrate the molecular mechanisms of saponin distribution by gene profiles. Results: There was saponin distribution in the root tissues differed between P. quinquefolius and P. notoginseng. Eight-eight and 24 potential biomarkers were detected by metabolome analysis, and a total of 340 and 122 transcripts involved in saponin synthesis that were positively correlated with the saponin contents (R > 0.6, P < 0.05) in the root tissues of P. quinquefolius and P. notoginseng, respectively. Among them, GDPS1, CYP51, CYP64, and UGT11 were significantly correlated with the contents of Rg1, Re, Rc, Rb2, and Rd in P. quinquefolius. UGT255 was markedly related to the content of R1; CYP74, CYP89, CYP100, CYP103, CYP109, and UGT190 were markedly correlated with the Rd content in P. notoginseng.

  • Recently, plenty of imported Chinese Mungbean is sold, for Korean Mungbean is expensive. But they say, Chinese Mungean has less delicacy and cooking quality. Above all, in comparison with Korean and Chinese Mungbeans properties they are different - Chinese Mungbean grain is twice in dimension, Chinese Mungbean is white and Korean one is yellow in peeled grain color. They are similar in size shape with the microscope. With Amylograph of Brabender the viscosity of Korean Mungbean is gradually and continually increased until heating from $25^{\circ}C$ to $92.5^{\circ}C$ and cooling to $25^{\circ}C$ again, but the one of Chines Mungbean is increased suddenly in 74$^{\circ}C$ and shows the abrupt break-down phenomenon. This same phenomenon is shown in swelling with melting-pointer, In $25^{\circ}C$, the cooling temperature, Chinese Mungbean is measured to 1400 B.U and Korean one 1600 B.U. With color-meter of Richard S. Hunter, 12% gel of Korean Mungbean starch is clear but Chinese one white. The texture of 12% gel of Chinese Mungbean starch with Rheo-meter becomes hardened much more than Korea one. As a result of sensory-test, color, cohesiveness, and flavors of Korean gel is preferred overwhelmingly.

  • This study is based on differences of syllable type between Korean and Chinese language pronunciation. For example, Nasal consonant ending 【n】 and 【${\eta}$】 reside in both Korean and Chinese phonetics simultaneously. However, in experiential training, Chinese learners will make errors in pronunciation of the Korean syllable nasal consonant ending like 【n】 and 【${\eta}$】. In the previous research, analysis of pronunciation errors were often based on the perspective of phonological system and combination of the phoneme rules. However, in this study, the analysis is based on the differences between Korean and Chinese syllables category to indicate the cause of pronunciation errors. The main findings of this study indicated that in the process of pronunciation of Chinese, nasal consonant syllable rime and its 【back】 tongue vowel are combined with each other. However, this rule does not apply in Korean pronunciation. Therefore, the Korean syllabic types like "앤, 응, 옹, 앵, 은, 온, 언" also exist in the Chinese language. When theChinese learners pronounce these types of syllables, the combination of the voweland nasal syllable rime rule will be taken, which will result in pronunciationerrors.

  • Purpose - As the U.S.-China trade war has become considerably worse, the Chinese government is considering applying non-tariff barriers to trade, especially local contents rule. The main purpose of this research is to check whether it is suitable for Korean investors to invest in the current Chinese capital market. Design/methodology - In order to check the stability of the recent Chinese capital market, we investigated the behavior of foreign equity investment (including Korean equity investment) in the Chinese capital market after China announced the Shanghai-Hong Kong Stock Connect (SH-HK Connect). In this paper, we researched whether international portfolio investment would or would not contribute to an increase the volatility of an emerging market's stock market (Chinese capital market) when foreign investors make investment decisions based on the objective of short-term gains by rushing into countries whose markets are booming and fleeing from countries whose markets are falling. Findings - The empirical results indicate that foreign investors show strong, negative feedback trading behavior with regard to the stock index of the Shanghai Stock Exchange (SSE), and when the performance of foreign investors in the Chinese stock market was fairly good. Also, we found evidence that the behavior of foreign investors significantly decreased volatility in SSE stock returns. Consequently, the SH-HK Connect brought on a win-win effect for both the Chinese capital market and foreign investors. Originality/value - It appeared that the Chinese capital market was very suitable for Korean investors after the China's declaration of the SH-HK Connect. However, the win-win effect was brought on by the Chinese government's aggressive capital control but the capital controls could possibly cause financial turmoil in the Chinese capital market. Therefore, Chinese reform in industrial structure and the financial sector should keep pace with suitable capital control policies.

  • The purpose of this study aimed to examine the perceptual pattern of the Korean coda consonants by Chinese learners of Korean. Given that Mandarin allows only two nasals (/n, ŋ/) in the coda position, it was predicted that Chinese learners of Korean had difficulty in discriminating Korean coda consonants. In the experiment, the subjects were 21 beginner-level Chinese learners of Korean. They participated in the discrimination task four times a year in which they were asked to choose the right Korean coda consonants after listening the word from Korean native speakers. The results demonstrated that 1) Chinese learners of Korean improved their perception of the Korean coda consonants. 2) But Chinese learners of Korean performed differently according to the type of Korean coda consonants. Korean consonants /n, p, k, m/ showed significant differences, but /l, ŋ, t/ did not.

  • As a part of R&D work for the high intensity proton linac of China Accelerator Driven Sub-critical System project, a superconducting half-wave cavity with a frequency of 162.5 MHz and an optimal beta of 0.15 (HWR015) has been developed at Institute of Modern Physics (IMP), Chinese Academy of Sciences. In this paper, the design and test results will be described in detail. We introduced a new stiffening strategy for the HWR cavity, the simulation results show that the cavity has much lower frequency sensitivity coefficient (df/dp), Lorentz force detuning coefficient (KL), and can achieve more stable mechanical properties. The performance of the HWR cavity operated in cryostat will be also reported.

  • The purpose of this study is to survey the wearing and purchasing situation related to brassieres between Korean and Chinese women and to analyze the differences among them. This study utilized a survey targeting 397 women in their 20's in Korea and China. The results were as follows: First, Korean women considered that their breasts are conical in shape, whereas Chinese women considered their breasts to have a flat shape. With regard to breast size, those of Chinese women are larger than those of Korean women. Moreover, Chinese women expressed a high rate of dissatisfaction with their breasts. Second, regarding the wearing condition of brassieres, while Korean women expected their brassiere to converge their breasts to the center, Chinese women expected their brassiere to support the breasts. It was found that many of them were dissatisfied with the shoulder straps and the center front wire. Third, in the results pertaining to the purchasing brassieres, although both Korean and Chinese Women mainly visited brand name stores to buy brassieres, compared with Chinese women, Korean women prefer to shop at home to buy the brassieres. In addition, they considered the compensation effect, size, activity, fabric and fit as the most important selection criteria when purchasing a brassiere.

  • Entering the Chinese animation market is a requirement for the survival and growth of Korean animation industry. While the size of Korean domestic animation market is not big enough to explain the investment for the production of animation project, the rapidly growing Chinese market provides a great potential for Korean animation. However, in recent few years, a high entrance barrier has been raised by Chinese government who aggressively enforce the strong policy to protect and develop the Chinese animation industry, by blocking the foreign animations out of Chinese domestic TV broadcasting. As a result, Chinese animation industry has witnessed a rapid growth enough to satisfy the domestic TV programming needs, and there seems no room for Korean animation to be exposed to Chinese animation consumers, whether through export of the program or co-production with Chinese companies. Through the study on Chinese government's policies and recent development of Chinese animation industry, this article is suggesting a new strategy for Korean animation industry to effectively exploit the Chinese market. In order to overcome the entrance barrier, Korean animation industry should satisfy the needs of Chinese government and industry for mutual benefit of both countries, and it can be accomplished by positioning Korean animation industry as a partner for Chinese industry, helping China in its way to the No.1 position in the global animation market. By providing the creative development capability, business knowhow and global marketing network for the co-production project, Korean animation industry can make a win-win situation for both countries, and at this point of stage, it would be the most effective way to make a meaningful presence of Korean animation industry in Chinese market.
