Xue Yun,Chen Jianbin 보안공학연구지원센터(IJUNESST) 2015 International Journal of u- and e- Service, Scienc Vol.8 No.1
The development of Web 2.0 and its social application lead to the appearance of Enterprise 2.0. Based on the discussion of self-organization of enterprise knowledge system in Enterprise 2.0, this paper built a super-network model integrated the interpersonal network and the knowledge object network as well as the definition of the super-network structure entropy. Take the knowledge governance as a regulator variable between enterprise knowledge system and its environment, a relationship between the performance of knowledge collaboration and structure entropy has been built, then a Logistic Growth Model has been proposed to analysis the self-organization process.

Yanxin Wang,Minfang Huang,Jianbin Chen 보안공학연구지원센터 2014 International Journal of u- and e- Service, Scienc Vol.7 No.6
We model a supply chain using system dynamics involving one retailer and two independent suppliers that are referred to as major supplier and backup supplier, respectively. Furthermore, the chain provides only one product; only the major supplier will experience disruptions, and the buyer uses the backup supplier either as a contingent supplier or a standby supplier. Our paper extends the existing literature and contributes by providing a better understanding of the impacts of supply disruptions on the system performance and shedding deeper insights into the value of a backup supply. Three models are built under supply disruption risks: supply chain without backup supplier, that with a contingent supplier and the one with a stand-by supplier. The retailer’s total profits are also compared to help the decision-makers choose the appropriate backup purchasing strategy.
Joint Template Matching Algorithm for Associated Multi-object Detection
( Jianbin Xie ),( Tong Liu ),( Zhangyong Chen ),( Zhaowen Zhuang ) 한국인터넷정보학회 2012 KSII Transactions on Internet and Information Syst Vol.6 No.1
A joint template matching algorithm is proposed in this paper to reduce the high rate of miss-detection and false-alarm caused by the traditional template matching algorithm during the process of multi-object detection. The proposed algorithm can reduce the influence on each object by matching all objects together according to the correlation information among different objects. Moreover, the rate of miss-detection and false-alarm in the process of single-template matching is also reduced based on the algorithm. In this paper, firstly, joint template is created from the information of relative positions among different objects. Then, matching criterion according to normalized cross correlation is generated for multi-object matching. Finally, the proposed algorithm is applied to the detection of watermarks in bill. The experiments show that the proposed algorithm has lower miss-detection and false-alarm rate comparing to the traditional NCC algorithm during the process of multi-object detection.

Based on the knowledge resource theory, we know that the nature of enterprise capability is knowledge. But knowledge accumulation of IT service outsourcing enterprises is largely due to knowledge transfer in the outsourcing process, which plays an important role in the promotion of enterprise capability. While knowledge transfer is mainly affected by the sender’s sending ability, receiver's absorption ability, knowledge transfer situation, the characteristics of knowledge and other factors. This article discusses the mechanisms and factors of knowledge transfer, analyzes the knowledge transfer process and effect on the subject of knowledge between the IT service outsourcing enterprises, then adopts system dynamics method to build the evolution model of IT service outsourcing enterprise knowledge transfer, and takes simulation experiments with Vensim tools, finally it proposes the evolution characters and transfer mechanism of knowledge transfer between enterprises. The conclusion can provide some suggestions for IT service outsourcing enterprises and a theoretical basis for the enterprises to develop knowledge transfer strategy.

Knowledge Heterogeneity is the source of Knowledge Collaboration in Enterprise while the Virtual Practice Community constructed with Web 2.0 technology is a very important way to gain heterogeneous knowledge. Active Cross-border Innovation makes the virtual practice community to be heterogeneous knowledge preference nowadays. However, the appropriate degree of knowledge heterogeneity that can excite the community to be synergy equilibrium is difficult to seek. This paper studies on the signaling game analysis of knowledge heterogeneity in Virtual Practice Community based on two-period reputation model. We mainly analyze the lower bound of optimal interval of knowledge heterogeneity to reveal the management meaning of this optimal interval.
CXCL-13 Regulates Resistance to 5-Fluorouracil in Colorectal Cancer

Purpose 5-Fluorouracil (5-Fu) is used as a conventional chemotherapy drug in chemotherapy for patients with advanced colorectal cancer, but many patients still suffer from treatment failure due to 5-Fu resistance. Emerging observations revealed the important role of chemokine (C-X-C motif) ligand 13 (CXCL-13) in tumor microenvironment and its relationship with prognosis in patients with colorectal cancer. This study is designed to reveal the important role of CXCL-13 in causing colorectal cancer resistance to 5-Fu. Materials and Methods CXCL-13 levels of patient's serum or cell culture supernatants were measured separately by enzyme-linked immunosorbent assay. In cell assays, cell viability is detected by Cell Counting Kit-8. Therefore, the recombinant human CXCL-13 was used to simulate its high expression in cells while its antibody and siRNA were used to reduce CXCL-13 expression in cells. Results In this study, we demonstrated that CXCL-13 is associated with 5-Fu resistance by culture medium exchange experiments and cytokine arrays of colorectal cancer resistant and nonresistant cells. Clinical studies showed that CXCL-13 is highly expressed in the serum of 5-Fu–resistant patients. High levels of serum CXCL-13 also predict a worse clinical outcome. The addition of recombinant CXCL-13 cytokine resulted in 5-Fu resistance, while its antibody overcame 5-Fu resistance, and knockdown of CXCL-13 expression by siRNA also reduced 5-Fu resistance, which can be saved by added recombination CXCL-13. Conclusion These results not only identify a CXCL-13 mediated 5-Fu resistance mechanism but also provide a novel target for 5-Fu–resistant colorectal cancer in prevention and treatment strategies.

The histological process of adventitious shoot regeneration from the leaf explants of Zizyphus jujuba ‘Huizao’was reported in this study. This is the first report on the detailed histological process of direct shoot regeneration from leaf explants in Z. jujube. Shoot regeneration was obtained from woody plant medium (WPM) supplemented with 2.27 μM thidiazuron (TDZ), 1.07 μM α-naphthalene-acetic acid (NAA) and 2.94 μM silver nitrate (AgNO3) for 10days in the dark followed by 3 weeks at a 14 hours photoperiod. The adventitious buds mostly formed from leaf veins and petioles, and the further histological studies revealed that there were multiple vascular bundles around leaf veins and the adaxial side of explants, and the adventitious buds directly originated from the parenchymatous cells around the vascular bundles without the intervening callus phase. After 3 days of culture, the parenchymatous cells started dividing and meristemoids formed thereafter. The meristematic cells continued division and subsequently gave rise to bud primordia. Well-developed shoot buds through direct organogenesis was achieved after 20 days of culture.

Dielectric and nonohmic properties of CaCu3Ti4O12 (CCTO) ceramics can be modified by addition of SrTiO3 (STO) in different molar proportions which were fabricated by a modified sol-gel method. XRD results indicated that all modified ceramics showed mixed phase consisting of both CCTO and STO. SEM images and grain size distribution probability also presented the change of microstructure with the addition of STO. The dielectric loss of the CCTO/0.4STO ceramics sintered at 1000 ◦C can be lower than 0.02 in a wide frequency (1 kHz–10 kHz), especially at 1 kHz, the dielectric loss of this sample is as low as 0.012. Furthermore, excellent nonlinear I–V electrical characteristic (high breakdown voltage to 54.15 kV/cm for CCTO/0.4STO sintered at 1000 ◦C) was observed as well. All the results indicated that the addition of STO does improve the dielectric properties and nonohmic characteristics of CCTO ceramics dramatically.
