  • The beef industry is an important part of livestock and meat production in China. China ranks third in the world for beef production. With the rapid development of the Chinese economy, beef consumption has grown rapidly, and beef consumption has been increasing with rising per capita gross domestic production. However, the domestic beef industry in China has not been able to keep pace with growth in consumption, making China a net importer of beef from other countries. Moreover, the volume of production has increased little despite rising demand. The slowing of growth in beef production in recent years has led to a sharp rise in beef prices. Domestic beef production and consumption is restricted by a shortage of beef cattle inventory. The Chinese beef industry is facing many technical problems including transformation of traditional practices, feeding and management systems, and genetic improvement of cattle breeds. The long-term, sustainable development of the Chinese beef industry is an important issue for China.

  • Female germ cell meiotic divisions are typically asymmetric, giving rise to two daughter cells with different sizes. Spindle movements including spindle migration from the oocyte center to the cortex and spindle rotation from parallel to perpendicular (typically in the mouse) at the cortex are crucial for these asymmetric divisions and therefore are crucial for gamete production. Different regulatory mechanisms for spindle movements have been determined in different species and a wide variety of different molecular components and processes that are involved in spindle movements have also been identified in different species. Here, we review the current state of knowledge as well as our understanding of mechanisms for spindle movements in different systems with focus on three main aspects: microtubules (MT), microfilaments (MF) and molecules associated with cytoskeletal organization as well as molecules that are not directly related to the cytoskeleton. How they might interact or function independently during female meiotic divisions in different species is discussed in detail.

  • With the globalization of Korean education and the rise in the average level of education, the number of international students in Korea, especially those from China, is rapidly increasing every year. This study aimed to provide the basic information for healthy dietary education by evaluating the dietary and nutritional status of Chinese students living in Gwangju province of Korea. Data from 468 subjects who met the study participation criteria and who had given their written informed consent were used for analysis. Of the total subjects, 52.4 and 80.1% were non-drinkers and non-smokers, respectively (p<0.01). It was observed that women were more stressed than men when they did not have convenient access to a Chinese food market near their place of residence (p=0.032). The subjects with a high cultural adaptation consumed kimbap (p<0.001) and pizza (p=0.017) more frequently than the subjects with a low cultural adaptation. An analysis of the nutrient quotient revealed that male scores were higher than those of the females with regard to water intake (p=0.035) and exercise level (p=0.021). For Chinese students living in Korea to maintain proper dietary habits, it is necessary to educate them on how to purchase convenience foods and improve their lifestyle, including limiting drinking and smoking. It is also necessary to develop emotional support programs for stress management and cultural adaptation.

  • SiC coating and SiC/glassy carbon composite coating were prepared on IG-110 nuclear graphite (Toyo Tanso Co., Ltd., Japan) to strengthen its inertness to molten fluoride salt used in molten salt reactor (MSR). Two kinds of modified graphite were obtained and correspondingly named as IG-110-1 and IG-110-2, which referred to modified IG-110 with a single SiC coating and a SiC/glassy carbon composite coating, respectively. Both structure and property of modified graphite were carefully researched and contrasted with virgin IG-110. Results indicated that modified graphite presented better comprehensive properties such as more compact structure and higher resistance to molten salt infiltration. With the protection of coatings, the infiltration amounts of fluoride salt into modified graphite were much less than that into virgin IG-110 at the same circumstance. Especially, the infiltration amount of fluoride salt into IG-110-2 under 5 atm was merely 0.26 wt%, which was much less than that into virgin IG-110 under 1.5 atm (13.5 wt%) and the critical index proposed for nuclear graphite used in MSR (0.5 wt%). The SiC/glassy carbon composite coating gave rise to highest resistance to molten salt infiltration into IG-110-2, and thus demonstrated it could be a promising protective coating for nuclear graphite used in MSR.

  • China has not thousands years history and culture but more than 50 times huge territory compare to Korea. Moreover, China is a multiracial country which has 56 minority races including Han race. Today's food culture of China has been established based on historic, regional, and racial features. China is located adjacent to Korea and historically has had close relationship with Korea. Moreover, China and Korea have had interaction in politic, economic, and cultural respects. In this aspect, the food culture of China has had great influence to the food culture of Korea. Therefore, this study purposed to understand the food culture of China more deeply which has been passed over, through researching food culture based on Chinese foods in five thousands historic stream. As the result of researching Chinese food by times in terms of food culture, which has been well known by only cuisine, the food culture of China had been changed by rise and fall of several dynasties. In addition, food styles had divided the south and north by inflowing western food materials and deep relation to Buddhism, Confucianism, Taoism, and the principles of yin-yang.

  • BACKGROUND/OBJECTIVES: Due to recent changes in social structure, single-person households are on the rise worldwide and therefore the interest in the quality of life of singles is increasing, but the research on the relationships related to their diet-related quality of life is scarce. This research analyzes the structural relations in the effect of convenience food satisfaction and quality of life according to dietary style of Korean, Japanese and Chinese singles. SUBJECTS/METHODS: The targets of this study were Korean, Japanese, and Chinese singles, identified as adults between the ages of 25 and 54, having economic capabilities or working and living alone, either legally or in actuality having no partner. A statistical analysis was conducted using SPSS12.0 for Windows and SEM using AMOS 5.0 statistics package. The reliability of these findings was supported by a Cronbach's alpha coefficient of 0.6 and higher for all the factors. In an attempt to study the level of satisfaction with convenience food in accordance to dietary style and the quality of life of singles, a structural equation model was constructed and analyzed. RESULTS: Of the three countries, regarding the effect of dietary style on singles' quality of life, the convenience-oriented style was found to have a negative effect on Korean singles' overall quality of life, but a positive effect on Japanese singles' overall quality of life, and a negative effect on Chinese singles' positive psychological aspect of quality of life. In addition, although Chinese singles have a high level of interest in health, they have an overall high level of satisfaction regarding fast food and its nutritional value. CONCLUSIONS: The number of singles in Korea, Japan, and China has been consistently increasing in recent years, and there is a need for continuous interest in their healthy dietary lifestyles in terms of convenience, economy, and taste.

  • Seismic design method based on bearing capacity has been widely adopted in building codes around the world, however, damage and collapse state of structure under strong earthquake can not be reflected accurately. This paper aims to present a deformation-based seismic design method based on the research of RC component deformation index limit, which combines with the feature of Chinese building codes. In the proposed method, building performance is divided into five levels and components are classified into three types according to their importance. Five specific design approaches, namely, "Elastic Design", "Unyielding Design", "Limit Design", "Minimum Section Design" and "Deformation Assessment", are defined and used in different scenarios to prove whether the seismic performance objectives are attained. For the components which exhibit ductile failure, deformation of components under strong earthquake are obtained quantitatively in order to identify the damage state of the components. For the components which present brittle shear failure, their performance is guaranteed by bearing capacity. As a case study, seismic design of an extremely irregular twin-tower high rise building was carried out according to the proposed method. The results evidenced that the damage and anti-collapse ability of structure were estimated and controlled by both deformation and bearing capacity.

  • After reform and openness action, china has been recorded high rate of increasing in export and continuous economic growth. Also their role in the international economy has been rise. The major reason of these incredible growth of China is the openness by a trade, after all the economic growth of China is evaluated an export-led growth. But, some insist that the growth of China has been accomplished by a domestic-based economy not but an export-led economy. For verification of former insists, using a yearly data, China exports and GDP, from 1979 to 2007 and performs time-series to examine an existence of causality between China's regional exports and GDP. As result of analysis, GDP and exports have two-way causality significantly when not considering region case. After the direction of Chinese reform, the east region has a strong significant relation, which support that export-led growth. While, middle and west region has weak causality between exports and GDP.

  • As the basic study to investigate the mechanism of improvement in the dyeing fastness of natural dyes on silk fabrics the optical behavior of tannin solution, the optimal condition of tannin treatment and the changes of the physical structure of silk fabrics were studied in the treatment of tannin. Results obtained were as follows ; 1.The K/S values of tannin-treated silk fabrics were not changed by tannin content on silk fabrics but yellowing of tannin in treatment condition. 2. As the concentration of tannin was increased in its treating condition, the tannin content and K/S vague of tannin-treated silk fabrics were increased. 3. Because tannin gave rise to yellowing by hydrolysis and oxidation at high temperature, the higher tannin-treating temperature was, the lower the tannin content and K/S values of silk fabrics 4. The tannin content of silk fabric was higher in acidic treating condition and the highest K/S value was showed at pH 5. 5. As the tannin content of silk fabric was increased, the value of ζ -potential of it became negative. 6. As the tannin content of silk fabric was increased, the crystallinity and crystallite size of it were decreased. This meant that the fraction of amorphous region in the fibers increased. And the degree of orientation of it was decreased with the tannin treatment.
