A Study on the Utilization Model of Social Network Service in China
Wen-Xiang Gong,Ji-Hye Lee 중앙대학교 한국전자무역연구소 2012 전자무역연구 Vol.10 No.2
온라인 산업의 발달과 스마트폰 보급의 확산에 따라 기존의 웹사이트가 일방적으로 제공하는 정보 또는 서비스를 이용하는 형태를 탈피하여 직접 참여하고 공유하는 웹 2.0 패러다임 환경이 확산되고 있다. 본 연구에서는 중국 온라인 시장에서의 소셜 네트워크 서비스가 마케팅 측면에서 어떠한 기능과 역할을 할 수 있는지에 대한 가능성을 탐색하고, 중국진출 한국기업에 중국 소셜 네트워크 서비스의 효과적인 적용방안을 제안하고자 한다. 이를 위해 대표적인 중국 소셜네크워크 서비스(Renren, Weibo, Baidu, Taobao)를 활용한 적용모델을 제시하고 그 활용가능성을 탐색해 보았다. 본 연구는 중국진출을 계획하는 한국기업들에게 중국의 소셜네트워크 서비스를 활용한 마케팅 활동에 도움을 주는 것을 목적으로 한다. The recent development of the online industry and a wider use of smartphones has brought about a new paradigm of Web 2.0, where customers participate firsthand in collecting and sharing information and services on the internet. They no longer depend on websites that unilaterally provide them with information and services. The paper examines what functions and roles social network service can perform in marketing and suggests a set of guidelines for the effective use of social setwork service in China. To that purpose, present a model employing a group of service networks such as renren.com, weibo.com, Baidu.com and Taobao.com and examine whether the model is applicable in the market. The purpose of this paper is expected to help Korean companies perform their marketing activities via Chinese social network services.

A Research for 3D Virtual Simulation Technology Application in Logistics System
Xiang-wen Li,Xin-ying Wang,Qian Gong 한국멀티미디어학회 2006 한국멀티미디어학회 국제학술대회 Vol.2006 No.-
The logistics system is important portion to the production and distribution fields and whole supply chain. The rationalization of logistics is one of the most significant methods to increase the productivity of supply chain. More attention is paid to the research of design and simulation of logistics system progressively. This paper mainly discuss key technology of simulation in logistics system, Computer realization of logistics system 3D virtual simulation, and the 3D multimedia technology in internet application in logistics simulation, introduces international leading 3D virtual logistics system simulation software.

Transgenic research was preformed by transferring a cyanobacterial (Nostoc flagelliforme) iron superoxide dismutase gene (NfFeSOD) into heavy metal hyperaccumulator Sedum alfredii via Agrobacterium-mediated method. Beyond expectation, NfFeSOD-overexpressing S. alfredii plants exhibited profound impairments, including plant growth retardation, abnormal root architecture, and reduced leaf greenness, photosynthetic efficiency and metal accumulation efficiency. Although transgenic plants appeared physiologically sensitive to high temperature, a higher relative biomass growth was still observed under long-term high temperature and osmotic stresses. Further investigation found that reactive oxygen species (ROS) homeostasis of transgenic plants was significantly affected, being ~50 % reduction of H2O2 level relative to wild-type plants. Gene transcription including ROS responsive genes was overall attenuated in transgenic plants, being more significant at normal temperature than at high temperature. In addition, ascorbate peroxidase (APX) activity was increased nearly twofolds in transgenic plants as compared to wild-type control. It may be inferred that ectopic NfFeSOD overexpression gives rise to a substantial increase of APX activity and leads to a sharp reduction of H2O2 level, thus impairing basal ROS signaling and plant growth. Specific genetic background of S. alfredii may be responsible for this sharp reduction of H2O2 level induced by NfFeSOD overexpression. S. alfredii plant has acclimated to elevated levels of ROS induced by heavy metals in native habitats and should require high ROS levels for basal signaling. We thus suppose that a sustained disturbance of high basal ROS signaling in metal hyperaccumulators may instead incur very sensitive response and thus result in profound growth impairments.

Core gut microbiota in Jinhua pigs and its correlation with strain, farm and weaning age
Hua Yang,Yingping Xiao,Junjun Wang,Yun Xiang,Yujie Gong,Xueting Wen,Defa Li 한국미생물학회 2018 The journal of microbiology Vol.56 No.5
Gut microbial diversity and the core microbiota of the Jinhua pig, which is a traditional, slow-growing Chinese breed with a high body-fat content, were examined from a total of 105 fecal samples collected from 6 groups of pigs at 3 weaning ages that originated from 2 strains and were raised on 3 different pig farms. The bacterial community was analyzed following high-throughput pyrosequencing of 16S rRNA genes, and the fecal concentrations of short-chain fatty acids (SCFAs) were measured by gas chromatograph. Our results showed that Firmicutes and Bacteroidetes were the dominant phyla, and Lactobacillus, Streptococcus, Clostridium, SMB53, and Bifidobacterium were the most abundant genera. Fifteen predominant genera present in every Jinhua pig sample constituted a phylogenetic core microbiota and included the probiotics Lactobacillus and Bifidobacterium, and the SCFAproducing bacteria Clostridium, Prevotella, Bacteroides, Coprococcus, Roseburia, Ruminococcus, Blautia, and Butyricicoccus. Comparisons of the microbiota compositions and SCFA concentrations across the 6 groups of pigs demonstrated that genetic background and weaning age affected the structure of the gut microbiota more significantly than the farm. The relative abundance of the core genera in the pigs, including Lactobacillus, Clostridium, Prevotella, Bacteroides, Roseburia, Ruminococcus, Blautia, and Butyricicoccus varied dramatically in pigs among the 2 origins and 3 weaning ages, while Oscillospira, Megasphaera, Parabacteroides, and Corynebacterium differed among pigs from different farms. Interestingly, there was a more significant influence of strain and weaning age than of rearing farm on the SCFA concentrations. Therefore, strain and weaning age appear to be the more important factors shaping the intestinal microbiome of pigs.
