Among these are various ethnic folk chess games. They are time-honored with many types such as the “Fang” chess of the Hui ethnic group, the “Jiu” chess of the Tibetans, the “King and Ministers” chess, the Mongolian chess, the Mongolian military chess, etc. These games embody distinctive ethnic and regional characteristics, as well as the cultural elements of a particular ethnic minority group. It is of great significance, therefore, to study the ethnic chess by collecting, documenting and comparing different types of related chess. The paper explores ways to standardize, protect and promote them scientifically in joint efforts, and draws a conclusion that examining their significance in the present era and the ethnic characteristics is the key to understanding the profound culture behind the chess.展开更多

The study area comprised three villages – Nambo, Huaymaha and Thapo, in the Phonxay district of Luang Prabang province. Three ethnic groups were covered by the study – Hmong, Khmu and Lao Loum. All three ethnic groups used soil color as main criteria for soil classification. However, even within the same ethnic group, sometimes different villages have differences in the way they classify soils; this was apparent for the Hmong ethnic group in the villages of Huaymaha and Nambo. A significant difference of the Lao Loum ethnic group from the other two, was the emphasis used in classifying soil types according to their water holding capabilities. In contrast, the Khmu and Hmong classified many soil types in relation to their rock content (‘with rock’ or ‘pure rock’ sometimesbeing used). The results of the study suggest that the ethnic groups classify the soils in relation to their potential for different types of agricultural production.展开更多

Every allelic frequency was comparatively analyzed with that of some main Chinese and Southeast Asia populations. It was found that 13 HLA-DRB1 alleles were detected among these 265 selected individuals, but other 13 alleles failed to be discovered by using the 23 pairs of primers designed in the present study. The most common alleles were HLA-DRB1*1501, HLA-DRB1*1601/2 and HLA-DRB1*1401/4 with the allele frequencies of 0.291, 0.198 and 0.106 respectively. Although alleles of HLA-DR1*0701/2, HLA-DRB1*08 and HLA-DRB1*1306/1406 could be detected also, but their frequencies were rather very low. The overall allele distribution profile on HLA-DRB1 of Zhuangs was much closed dramatically to those of Buyis, Northeast Thais, Dai Lues, Southern Hans and Singapore Chinese, but was more far away from that of northern Hans and Hanai Kinhs, as compared to the representative ethnic groups in Southeast Asia. In addition, the blank of HLA-DRB1*1502 was a characteristic allele for Zhuangs was commonly detected in Southeast Asia, especially in Thais. It is concluded that a very close genetic relationship exists between Zhuangs and Buyis on the basis of their extremely similar background on HLA-DRB1 locus.展开更多

Meanwhile, New Year, Pray in Spring and Return in Autumn not only play significant roles in agricultural production, but also evolve to farming holidays which are enriched with more social connotations. Centered on husbandry and production, some folklore that is rich in local color has been formed in Dong society. The writer introduced some farming ritual of Dong ethnic group, such as, sowing, Kai Yang Men, Rain-praying, Chang Xin, reaping and Lunar New Year, summarized their belief in the land worship, festival ritual, ancestor ritual and ceres ritual. It is concluded that sacrifice is a production-related folklore, which is formed by repeated operation and constant practice. Some taboos were also prohibited in agricultural sacrifice because people were not able to change the unfavorable reality of farming with their insufficient experience and knowledge; however, they resorted to witchcraft for the purpose of harvest. It is believed that the activity of sacrifice will also be kept in the life of Dong ethnic group due to their dependency on agriculture and the land.展开更多

Haplotype diversity and the mean pairwise differences were 0.9903±0.0013 and 5.7785 in HVS-I, and 0.9777±0.0013 and 3.5819 in HVS-II, respectively. By analyzing the hypervariable domain from nucleotide 1,6180 to 1,6193 in HVS-I, we defined some new types of sequence variations. We also compared the relationship between Tu population and other populations using mtDNA HVS-I sequences. According to Rst genetic distances, the phylogenetic tree showed that the Tu population, the Xi'an Han population, the Chinese Korean, and the Mongol ethnic group were in a clade. This indicated a close genetic relationship between them. There were far relations between the Tu population and other Chinese southern Han populations, Siberian, European, African, and other foreign populations. The results suggest that Tu population has a multi-origin and has also merged with other local populations.展开更多

The majority of studies primarily focus on the detection of the perceptual demands of consumers from the target product category. A pan-ethnic-group products form gene clustering method based on emotional semantic is constructed. Consumers' perceptual images of the pan-ethnic-group products are obtained by means of product form gene extraction and coding and computer aided product form clustering technology. A case of form gene clustering about the typical pan-ethnic-group products is investigated which indicates that the method is feasible.

Results Twenty-one alleles were detected for HLA-A, 44 for HLA-B, and 26 for HLA-DRB1. The most frequent alleles were HLA-A*2402(0.2097), HLA-B*1302(0.0699), and HLA-DRB1*0701(0.1237). The most common HLA-A-B-DRB1 haplotype were A*3001-B*1302-DRB1*0701, A*0101-B*3701-DRB1*1001, followed by the A*0201-B*4601-DRB1*0901, A*2402-B*4801-DRB1*1101, A*2402-B*5201-DRB1*1501, A*3201-B*3503-DRB1*1301, and A*3303-B*5801-DRB1*0301, which were also presented in Chinese populations. Conclusion The data can be used in forensic and paternity tests to estimate the frequency of a DNA profile or anthropologic research. The characteristics of the distribution of HLA alleles revealed that Mongolia ethnic group is characterized by northern Mongolian Chinese.
