  • This paper concerns the design and implementation of a Bandwidth Variable Digital Chirp Generator (DCG) for the radar altimeter. A double SRAM parallel structure is used to breakthrough the upper DCG bandwidth limited by the highest clock frequency of the digital chips. An experimental system working in the waveform storage method has been implemented. We show that the bandwidth changed according to the radar altimeter's requirement and the design released the stringent speed requirement of the chips fur making a variable wide bandwidth DCG.

  • This study was conducted to investigate the effect of Chinese artichoke powder on the physicochemical properties and the sensory characteristics of yanggaeng. According to the increasing contents of Chinese artichoke powder, the $^{\circ}Brix$ value and pH levels of yanggaeng were significantly decreased whereas the moisture contents of yanggaeng was significantly increased. The result of color measurement shown that L value of groups containing Chinese artichoke powder was lower than that of control group, but a value and b value of groups containing Chinese artichoke powder were higher. Texture measurement score in terms of cohesiveness, chewiness, and brittleness for yanggaeng were significantly decreased according to the levels of added Chinese artichoke powder content. The contents of total polyphenol, DPPH radical scavenging activity, and NSA of groups containing Chinese artichoke powder were higher than those of control group. As Chinese artichoke powder increased, antioxidative activity also became bigger. Sensory evaluation scores in terms of appearance, odor, taste, texture, and overall preference of groups with 2% and 4% of Chinese artichoke powder did not show any significantly differences when compared to the control group. Based on these findings, current study suggest that addition of 4% Chinese artichoke powder was the best substitution ratio for yanggaeng.

  • Endothelial cell injury is a major contributor to cardiovascular diseases. The 2,3,5,4'-Tetrahydroxystilbene-2-O-β-D-Glucoside (TSG) contributes to alleviate human umbilical vein endothelial cells (HUVECs) injury through mechanisms still know a little. This study aims to clarify the TSG effects on gene expression (mRNA and microRNA) related to oxidative stress and endoplasmic reticulum stress induced by H2O2 in HUVECs. We found that TSG significantly reduced the death rate of cells and increased intracellular superoxide dismutase activity. At qRT-PCR, experimental data showed that TSG significantly counteracted the expressions of miR-9-5p, miR-16, miR-21, miR-29b, miR-145-5p, and miR-204-5p. Besides, TSG prevented the expression of ATF6 and CHOP increasing. In contrast, TSG promoted the expression of E2F1. In conclusion, our results point to the obvious protective effect of TSG on HUVECs injury induced by H2O2, and the mechanism may through miR16/ATF6/ E2F1 signaling pathway.

  • Traditional Chinese cuisine, which is highly evaluated with respect of taste and techniques, is built based on a sound healthy philosophy and distinct dietary culture, with emphasis on the unity of human beings and nature. The traditional cuisine utilized food materials according to the physical status and seasons, which is still a valuable principle in the modem diet. According to relevant research, the nutrient retention in Chinese cooking is acceptable. However, following the rapid growth of domestic economy, the Chinese diet is in danger of losing its original merits, especially when eating out. The excessive desire for food enjoyment leads to a rapid increase in the prevalence of obesity and chronic disease. It is a critical point to review the characteristic of traditional Chinese cuisine and lead the trend to a healthy direction.

  • Okra (Abelmoschus esculentus (L.) Moench) has gained more popularity as an economically significant plant for its nutritional and medicinal value, especially in China. During 2014-2016, the root disease of okra was discovered in four okra commercial fields surveyed in China. A fungul was isolated from the infected tissues, and was identified by Verticillium dahliae based on morphological characteristics. Pathogenicity test demonstrated that the fungus was pathogenic on okra, and fulfilled Koch's postulates. The analysis of three sequences revealed 99-100% identity with the reported V. dahliae strain in GenBank. Neighbor-joining analysis of the gene sequences revealed that the representative isolates were clustered with V. dahliae. To the best of our knowledge, this is the first report of Verticillium wilt of okra in China.

  • In this manuscript, a review of the diversity of Chinese indigenous goat breeds according to data from body stature and appearance, chromosome group, blood proteins, DNA molecular markers (mitochondria DNA, random amplified polymorphic DNA, microsatellite DNA, major histocompatibility complex) has been introduced. All of these provide efficient tools for the diversity analysis of Chinese indigenous goat breeds and are very important for biodiversity conservation, restoration of declining goat breeds, the priority defining in Chinese indigenous goat breeds' protection and the selection of nature preservation zones. Many Chinese indigenous goat breeds with small population size in the isolated mountains or reservoir areas are verging the potential threat of extinction, effectively lost with the rapid destroying of ecological environment. On the other hand, as a result of the introduction of modern commercial goat breeds and shortage of effective conservation, some populations, such as Small-xiang goat and Tibetan goat decrease rapidly in number of sires. In the interests of the long-term future of the goat breeds in China, conservation of goat breeds' genetic resources should be considered urgently and some conservation measures should be adopted. In addition, the continuing development of molecular biology will further enhance conservation of diversity of Chinese indigenous goat breeds.

  • The study is being conducted to investigate the perceptions and preferences of the Korean kimchi by the Chinese international students in Jeonbuk area. Self-administered questionnaires were collected from 197 male (48.9%) and 203 female (51.1%) students. Statistical data analysis is being completed using SPSS v. 12.0. Approximately 95% of Chinese female and 91% of male students know about kimchi before coming to Korea through the Korean movies and dramas. The perceptions for kimchi according to the residence period showed a significantly difference 'kimchi is a nutritious and health food' (p<0.05), 'kimchi has good taste but too hot to eat' (p<0.05), and 'Kimchi is difficult to eat because of the smell' (p<0.05). Approximately 52% of Chinese female and 44% of male students consumed kimchi once or twice a day. The most popular form of kimchi among the 13 varieties was baech kimchi. Chinese female students preferred the 'kkakdugi' (p<0.05), 'chonggak kimchi' (p<0.05), and 'young radish kimchi' (p<0.05) more than the male students. The most liked reason was the 'refreshing taste' (44.8%) whereas the most disliked reasons were 'unfamiliar with eating kimchi' (28.7%) and 'sour taste' (24.2%). Approximately 85% of Chinese female and 60% of male students would like to experience making kimchis by themselves. Extended kimchi consumptions for Chinese answered 'not too fish-like smell' (36.0%), 'not too overly-ripe' (34.5%), 'not too sour' (25.4%), and 'not too hot' (25.4%). Therefore, in order to improve the awareness for kimchi among Chinese students, we need to relate kimchi with the taste of Chinese traditional foods.
