  • With the increased economic profit in China, people tend to give more attention to the nurturing of children. The change in the food markets directly connected to the infants' health seem to have brought various consumption patterns different than before. Based on the actual condition survey operated by this research, the expansion in the scale of consumption and preference to the imported food for infants appeared in the Chinese food markets for infants. The rapidly increased amount of the online purchases of the food for Chinese infants was checked through the condition survey. Based on the analysis results, with the purpose of increasing the purchase opportunities of the Korean food for infants to the Chinese consumers, it should not only perform the promotion activities such as the promotion for the product's superiority and various promotional event, but also establish the pricing strategy for each entry step to the Chinese market. Because the purchase experience of the Korean food for infant plays the important role for the additional payments decision, it is estimated that there is a need to expand the opportunities for the Chinese consumers to approach the Korean food for infants both directly and indirectly.

  • The antimutagenic effects of buchu kimchi and Chinese cabbage kimchi and theri cytotoxic effects against human cancer cell line were investigated in the Salmonella typhimurium system and MTT assay, respectively. Leek and Chinese cabbage were aslo evaluated in the same system. Buchu kimchi was fermented at 15 $^{\circ}C$ for 4 days . Buchu kimchi samples showed somewhat higher antimutagenic effects against aflatoxin B1(AFB1) than CHinese cabbage kimchi in Salmonella typhimurium TA100 strain. There was no difference onthe antimutagenic activity according to the length of fermentation . Leek exerted stronger antimutagenicity against AFB1 than Chinese cabbage in the Ames assay. In MTT assay, 6-day fermented buchu kimchin revealed the highest cytotoxicity against AGS human gastric adenocarcinoma cells in which 62% and 82% of the inhibition were observed wiht the addition of 100ug, 400ug/well, respectively. Buchu kimchi samples caused 60~70% inhibition on the proliferation of HT-29 at 400ug/well. Leek exhibited higher antiproliferative effect against both AGS cells and HT-29 cells than Chinese cabbage in MTT assay. From these results, it is considered that buchu kimchi has stronger antimutagenic and in vitro anticancer effects than Chinese cabbage kimchi and the high inhibition rate of buchu kimchi probably results from leek, the major ingredient of buchu kimchi .

  • Objective: Information regarding the vitamin content of silage is limited. This study investigated the changes in the vitamin content of alfalfa and Chinese leymus silages with or without a lactic acid bacterial inoculant. Methods: Alfalfa at the early flowering stage and Chinese leymus at the full-bloom stage were harvested. The treatments for each forage type were control (deionized water only) and $1{\times}10^6$ colony-forming units Lactobacillus plantarum (LP)/g fresh matter. After 45 days of ensiling, all silages were sampled for evaluating the vitamin content, fermentation quality and chemical composition. Results: The LP inoculant decreased the pH value and ammonia nitrogen content of the alfalfa and Chinese leymus silages and significantly (p<0.05) increased the lactic acid, acetic acid concentrations and Flieg's points. Prior to ensiling, the levels of five B-group vitamins (thiamin, riboflavin, niacin, pantothenic acid, and pyridoxine) and ${\alpha}$-tocopherol in alfalfa were significantly (p<0.01) higher than those in Chinese leymus. Ensiling decreased the levels of the five B-group vitamins in both alfalfa and Chinese leymus while increasing the ${\alpha}$-tocopherol content of Chinese leymus. The thiamin, riboflavin, niacin and pantothenic acid levels in the LP-treated silage were significantly (p<0.05) lower than those in the untreated silage for the alfalfa and Chinese leymus. The ${\alpha}$-tocopherol content in the LP-treated alfalfa silage was significantly (p<0.05) higher than that in the untreated alfalfa silage. There was no significant (p>0.05) difference in pyridoxine content between the untreated and LP-treated silages for both forages. Conclusion: With or without LP inoculation, the levels of the five B-group vitamins (thiamin, riboflavin, niacin, pantothenic acid, and pyridoxine) in alfalfa and Chinese leymus decreased after 45 days of ensiling, while the ${\alpha}$-tocopherol content of Chinese leymus increased. The LP inoculant improved the fermentation quality of both the alfalfa and Chinese leymus silages but increased the thiamin, riboflavin, niacin, and pantothenic acid loss in the two forages after fermentation.

  • A superconducting ion-Linac (iLinac), which is supposed to work as the injector in the High Intensity heavy-ion Accelerator Facility project, is under development at the Institute of Modern Physics (IMP), Chinese Academy of Sciences. The iLinac is a superconducting heavy ion linear accelerator approximately 100 meters long and contains 96 superconducting cavities in two types of 17 cyromodules. Two types of superconducting resonators (quarter-wave resonators with a frequency of 81.25 MHz and an optimal beta β = v/c = 0.07 called QWR007 and half-wave resonators with a frequency of 162.5 MHz and an optimal beta β = 0.15 called HWR015) have been investigated. The cavity design included extensive multi-parameter electromagnetic simulations and mechanical analysis, and its results are described in details. The fundamental power coupler and cavity dynamic tuner designs are also presented in this article. The prototypes are under manufacturing and expected to be ready in 2023.

  • The purpose of this study was to examines the changes in Chinese women's clothing resulted from the introduction of Western culture in the first hal# of the 20th century in terms of Chinese view of the world and their attitude towards European culture. The clothes are divided into four types according to their characteristics : traditional Chinese type, China-Europe adjustment type, China-Europe blend type and European type. As for the research method, both literature and visual data are examined. The traditional Chinese type showed changes only in the width and length retaining the features of the traditional qipao until the 1910s. The China-Europe adjustment type used the same flat pattern making of traditional Chinese dress while imitating only the appearances of European one-piece, two-piece and three-piece dresses. It also was presented with European accessaries and hair-styles. The China-Europe blend type, starting to appear with the introduction of the three-dimensional pattern making from the Europe in the 1930s, showed a perfect mixture of European and traditional Chinese costumes in the early 1940s when the Chinese learned and adapted the European pattern making. The European type was the most modernized designs using a variety of European-style details and constructions as the traditional clothing started to have unrestricted European-style changes. Great significance can be found in the fact that the Chinese modified their garments by themselves using the pattern mating they learned from the Europe.

  • This study reports the identification of species of Colletotrichum strains originating from red-pepper and Chinese matrimony vine in Cheongyang. Ninteen isolates of red-pepper and 26 Coiletotrichum isolates of Chinese matrimony vine were compared with 5 isolates of strawberry representing C. gloeosporioides, by use of morphological and cultural criteria. Twenty three isolates among 26 isolates from Chinese matrimony vine were identified as C. acutatum, characterized by the low growth rates and the low sensitivity to carbendazim and diethofencarb. Also, all the isolates of red-pepper were identified as C. acutatum, showing the same characteristics as those of Chinese matrimony vine. Three and five isolates from Chinese matrimony vine and strawberry, respectively, were identified as C. gloeosporioides, characterized by the high growth rates and the high seneitivity to carbendazim and diethofencarb. There were differences in colony color and pathogenicity between Chinese matrimony vine isolates and red-pepper isolates of C. autatum. The isolates of C. acutatum from Chinese matrimony vine producing orange colored colonies with abundant spores showed the strong pathogenicity to Chinese matrimony vine, although they could not infect fruits of red-pepper by the wound inoculation. However, red-pepper isolates of C. acutatum producing gray colonies showed the strong pathogenicity to Chinese matrimony vine as well as red-pepper. Furthermore, comparative study on PCR amplification of ITS regions of rDNA was carried out using a number of Colletotrichum isolates. A species-specific primer could be used for the identification of C. acutatum from red-pepper and Chinese matrimony vine.

  • In traditional Chinese medicine, some herbs are used after toasting or roasting. The process is called "Zhi Tan" in Chinese, which means charring, and the herbs after the treatment is called carbon medicine. Carbon medicine is widely used to arrest bleeding in traditional Chinese medicine. The paper introduces the records, development and applications of carbon medicine in ancient China. The earliest record found about carbon medicine was in the remains of Han dynasty (BC206-A.D.8). The paper also introduces the process of charring herbs and mechanism of carbon medicine in arresting bleeding. Calcium iron and tan released during the charring are believed as main factors for arresting bleeding, helped with porous surface structure of active carbon.

  • Named entity classification of Wikipedia articles is a fundamental research area that can be used to automatically build large-scale corpora of named entity recognition or to support other entity processing, such as entity linking, as auxiliary tasks. This paper describes a method of classifying named entities in Chinese Wikipedia with fine-grained types. We considered multi-faceted information in Chinese Wikipedia to construct four feature sets, designed different feature selection methods for each feature, and fused different features with a vector space using different strategies. Experimental results show that the explored feature sets and their combination can effectively improve the performance of named entity classification.

  • Intrusion detection techniques based on virtual machine introspection (VMI) provide high temper-resistance in comparison with traditional in-host anti-virus tools. However, the presence of semantic gap also leads to the performance and compatibility problems. In order to map raw bits of hardware to meaningful information of virtual machine, detailed knowledge of different guest OS is required. In this work, we present VDSM, a lightweight and general approach based on driver separation mechanism: divide semantic view reconstruction into online driver of view generation and offline driver of semantics extraction. We have developed a prototype of VDSM and used it to do intrusion detection on 13 operation systems. The evaluation results show VDSM is effective and practical with a small performance overhead.
