Analysis of Religious Development and Characteristics in Southeast Asia
Zong Wei,Ren Liang,Qu Jinshuai 아시아사회과학학회 2020 Jornal of Asia Social Science Vol.1 No.2
Southeast Asia is not only one of the birthplaces of human civilization, but also the region with various and complex religions in the world. Its religious development has a long history, which can be traced back to the period of primitive society. With the development of human civilization and social productive forces, the improvement of natural environment and cross-regional religious and cultural exchanges, the religious culture in Southeast Asia shows the characteristics of diversity, variability and mixing. This paper divides the development of religion in Southeast Asia into two stages, and focuses on the development and characteristics of different religions in Southeast Asia before the introduction of foreign religions and the development of emerging religions in Southeast Asia.

Output-only modal parameter identification of civil engineering structures
Ren, Wei-Xin,Zong, Zhou-Hong Techno-Press 2004 Structural Engineering and Mechanics, An Int'l Jou Vol.17 No.3
The ambient vibration measurement is a kind of output data-only dynamic testing where the traffics and winds are used as agents responsible for natural or environmental excitation. Therefore an experimental modal analysis procedure for ambient vibration testing will need to base itself on output-only data. The modal analysis involving output-only measurements presents a challenge that requires the use of special modal identification technique, which can deal with very small magnitude of ambient vibration contaminated by noise. Two complementary modal analysis methods are implemented. They are rather simple peak picking (PP) method in frequency domain and more advanced stochastic subspace identification (SSI) method in time domain. This paper presents the application of ambient vibration testing and experimental modal analysis on large civil engineering structures. A 15 storey reinforced concrete shear core building and a concrete filled steel tubular arch bridge have been chosen as two case studies. The results have shown that both techniques can identify the frequencies effectively. The stochastic subspace identification technique can detect frequencies that may possibly be missed by the peak picking method and gives a more reasonable mode shapes in most cases.

Analysis of the Relationship between MHC-DRB1 Gene Polymorphism and Hydatidosis in Kazakh Sheep
Li, Ren-Yan,Jia, Bin,Zhang, Wen-Ju,Zhao, Zong-Sheng,Shi, Guo-Qing,Shen, Hong,Peng, Qiang,Lv, Li-Min,Zhou, Qi-Wei,Du, Ying-Chun Asian Australasian Association of Animal Productio 2010 Animal Bioscience Vol.23 No.9
The objective of this work was to analyze the relationship between ovine major histocompatibility complex (MHC) DRB1 gene polymorphism and genetic resistance to hydatidosis in Kazakh sheep. The Ovar (ovine MHC) class II DRB1 second exon was amplified by polymerase chain reaction (PCR) from DNA samples of 702 Kazakh sheep, including 302 sheep with hydatidosis and 400 health controls. PCR products were characterized by the restriction fragment length polymorphism (RFLP) technique using five restriction enzymes, i.e., MvaI, HaeIII, SacI, SacII and Hin1I, yielding 14 alleles and 28 genotypes. Comparing the frequency of genotypes in hydatidosis sheep with the control group, it was found that the genotype frequencies of MvaIbc, Hin1Iab, SacIIab, HaeIIIde, HaeIIIdf and HaeIIIdd in control sheep were significantly (p<0.01) higher than in hydatidosis sheep, indicating that a significant correlation existed between these genotypes and resistance to hydatidosis. Genotype frequencies of MvaIbb, SacIIaa, Hin1Ibb and HaeIIIef in sheep with hydatidosis were extremely significantly (p<0.01) higher than in the control group, and the genotype frequency of HaeIIIab was significantly higher (p<0.05), indicating that a marked correlation existed between these genotypes and susceptibility to hydatidosis. By way of analyzing haplotype with these resistant genotypes, the hydatidosis resistant haplotype MvaIbc-SacIIab-Hin1Iab of Kazakh sheep was screened out, and then verified through artificial hydatid infection in sheep. The results indicated that the infection rate of sheep with the resistant haplotype of hydatidosis was significantly lower (p<0.01) than without this resistant haplotype. It showed that the genic haplotype MvaIbc-SacIIab-Hin1Iab of Ovar-DRB1 exon 2 was the resistant haplotype of hydatidosis in Kazakh sheep.

To investigate the anti-obesity and hypolipidemic effects of Alpinia officinarum ethanolic extract (AOE) for the first time, anti-obesity models in vivo were used. Ten male Sprague-Dawley rats were fed normal control diet (NC); other groups of rats were fed a high-fat diet (HFD) with or without different proportions of AOE (AOE-1, 3%; AOE-2, 5%) for 6 weeks to examine feed intake, body and adipose tissue weight, serum total cholesterol (Total-C), triacylglycerol (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and leptin levels, alanine aminotransferase (ALT) and aspartate aminotranferase activities, hepatic Total-C and TG levels, and the pathological changes in liver and epididymal adipose tissues. Interestingly, feed intakes among the experimental groups were not significantly different. Body weight gains were significantly lowered in the AOE-1 and AOE-2 groups compared with the HFD group (P<.05) and near to the level of the NC group. AOE also improved the lipid profile in serum and the pathological changes in liver and adipose tissue and decreased the relative weights of epididymal and perirenal white adipose tissues. They improved lipid profile by lowering serum Total-C, TG, and LDL-C concentrations, leptin content, and the atherogenic index compared with the HFD group. The HDL-C concentration and the ratio of HDL-C/Total-C significantly increased compared with those of the HFD group. The serum ALT activity of the AOE-2 group was notably lower than that of the HFD group. Our data suggest that AOE can be considered as an anti-obesity agent that is effective for suppressing body weight gain and decreasing lipid profile.

Two New Species in the Family Cunninghamellaceae from China
( Heng Zhao ),( Jing Zhu ),( Tong-kai Zong ),( Xiao-ling Liu ),( Li-ying Ren ),( Qing Lin ),( Min Qiao ),( Yong Nie ),( Zhi-dong Zhang ),( Xiao-yong Liu ) 한국균학회 2021 Mycobiology Vol.49 No.2
The species within the family Cunninghamellaceae are widely distributed and produce important metabolites. Morphological studies along with a molecular phylogeny based on the internal transcribed spacer (ITS) and large subunit (LSU) of ribosomal DNA revealed two new species in this family from soils in China, that is, Absidia ovalispora sp. nov. and Cunninghamella globospora sp. nov. The former is phylogenetically closely related to Absidia koreana, but morphologically differs in sporangiospores, sporangia, sporangiophores, columellae, collars, and rhizoids. The latter is phylogenetically closely related to Cunninghamella intermedia, but morphologically differs in sporangiola and colonies. They were described and illustrated.

The Asian long‐horned beetle (ALB) is one of the most important wood‐boring insects worldwide that damages broad‐leaved trees, primarily poplar, willow, elm and maple. Based on the color of the spots on the elytra, the beetles are separated into white‐spotted (ALB‐W) and yellow‐spotted (ALB‐Y) Asian long‐horned beetles. In order to clarify the morphology of sensilla on antenna, maxillary palp and labial palp of ALB‐W and ALB‐Y larvae, we studied the typology, morphology, number and distribution of the sensilla by scanning electron microscopy. The results showed that: (i) the antennae of two biotypes had five types of sensilla, including three types of sensilla basiconica (b.) and two types of sensilla twig basiconica (s.tb); numbers of b.1, b.2, b.3 and s.tb1 on antenna were not significantly different (P > 0.05) between two biotypes, and the numbers of s.tb2 were significantly different (P < 0.05); (ii) the maxillary palp of two biotypes had four types of sensilla, including sensilla styloconica (st.), two types of s.tb and digitiform sensilla (ds.); the numbers of st. and ds. on the maxillary palp were not significantly different (P > 0.05) between two biotypes, and the numbers of s.tb1 and s.tb2 were significantly different (P < 0.05); (iii) the labial palp of two biotypes had four types of sensilla, including b., st. and two types of s.tb, and the numbers of b.3, st., s.tb1 and s.tb2 on the labial palp were not significantly different (P > 0.05) between two biotypes. We discuss the relationships between sensilla and damage caused by the larvae inside the host trees.

Fabrication and properties of machinable SiC/h-BN Nano-composites
Hai-yun Jin,Nai-kui Gao,Zong-ren Peng,Guan-jun Qiao,Ji-qiang Gao 한양대학교 세라믹연구소 2008 Journal of Ceramic Processing Research Vol.9 No.6
SiC/BN ceramic nano-composites powders were synthesized by an in-situ recation method and the composites were sintered by hot pressing in a N2 atmosphere. The microstructure, secondary phase and grain boundaries were characterized using a range of analytical techniques including TEM, SEM and XRD. The mechanical properties were determined, when the BN content is increaed because the nano-sized h-BN crystals were homogeneously dispersed around the SiC grains of the matrix, the fracture strength of the nano-composites decreased more slowly than that of the SiC/h-BN micro-composites, but the hardness of the composites decreased sharply and the machinability properites were improved noticeably.
