The Model of Mobile Knowledge Services System in the Management of Complex Cluster Project  [PDF]
Yong Liu, Bingxin Liu
iBusiness (IB) , 2011, DOI: 10.4236/ib.2011.31006
Abstract: Cluster projects are projects of large-scale or with huge investment, such as Beijing 2008 Olympic Games and Shanghai 2010 Expo. A lot of on-site management works are involved in the process of cluster project management, especially the treatment of sudden accidents which would produce plenty of knowledge and experience. As cluster project on-site management spots change frequently, knowledge produced by mobile workers in the process of on-site management is hard to be saved into the knowledge repository on time. It may cause a knowledge distortion or even missing. On the other hand, in the process of cluster project management, a lot of knowledge is required by on-site workers to deal with on-site activities. However, due to lack of effective mechanisms for knowledge communion, they often face the risk of making wrong decisions. To solve the problems of knowledge management and acquisition in the process of cluster project on-site management, this paper presents a system model for mobile knowledge service.
Parametric Decomposition of the Malmquist Index in Output-Oriented Distance Function: Productivity in Chinese Agriculture  [PDF]
Bingxin Yu, Xiyuan Liao, Hongfang Shen
Modern Economy (ME) , 2014, DOI: 10.4236/me.2014.51009

This paper decomposes the Malmquist productivity index into several assembling components: technical change (further break down into technical change magnitude, input bias and output bias), technical efficiency change, scale efficiency change, and output-mix effect. A translog output distance function is chosen to represent the production technology and each component of the Malmquist index is computed using the estimated parameters. This parametric approach allows us to statistically test the hypothesis regarding different components of the Malmquist index and the natural of production technology. The empirical application in Chinese agriculture shows that the average productivity grows at 2 percent per year during 1978-2010. This growth is mostly driven by technical change, which is found to be neutral.

In the early 20th century, management accounting was created with Taylor’s theory of scientific management. Management accounting is a continuous improvement process that provides value added value, design, measure and manage financial and non-financial information systems for enterprises. This process directs the management actions, motivates behaviour, supports and creates cultural values, which are needed to achieve organizational strategy, tactics and business objectives. The research and application of management accounting in China started late. It started in the late 1970s and early 1980s. During the period of about 30 years, management accounting has made great progress in both theory and practice. Many facts have proved that China’s management accounting has gradually shifted from quantity and quota management to management of cost and value, and from project and department management to comprehensive and strategic management. In recent years, with the implementation of fiscal policies such as department budget, investment review and performance appraisal, “comprehensive budget”, “zero-base budget”, “budget control”, “responsibility assessment” and other modern management accounting theories and methods have been applied in various enterprises in China. But the time that management accounting is formed and developed in China is not long after all. There are many defects and deficiencies in China’s management accounting. The theoretical structure, scope of research and practical application of management accounting are to be improved and enriched, and there is still considerable space for development. The problem is more serious in small and medium-sized enterprises [1]. This paper studies the current development status of management accounting in small and medium-sized enterprises and factors that affect the management accounting in the small and medium-sized enterprises, then proposes solutions to meet the development needs of management accounting in small and medium-sized enterprises.
Analysis on the Factors Affecting the Capital Structure of Small and Medium-Sized Enterprises in China  [PDF]
Jiaxu Jiang, Futang Dong, Bingxin Du
American Journal of Industrial and Business Management (AJIBM) , 2018, DOI: 10.4236/ajibm.2018.81010
Abstract: The capital structure of small and medium-sized enterprises is closely related to enterprise financing. At present, the capital structure of small and medium-sized enterprises in China is unreasonable. There are disadvantages such as low proportion of internal financing, single external financing channels and excessive short-term liabilities. The theory of enterprise capital structure studies how the enterprise arranges its capital structure in its development or contraction, which means how the enterprises determine the ratio of their own capital, equity capital and debt capital in order to maximize their market value. In other words, how to find the optimal capital structure of the enterprise is the central task of the theory. This paper starts from the economic environment and characteristics of small and medium-sized enterprises, discusses the internal and external factors affecting the capital structure of small and medium-sized enterprises and puts forward the countermeasures and suggestions for optimizing capital structure of small and medium-sized enterprises.

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0099920
Abstract: Objective Collagen peptides (CP) compounds, as bone health supplements, are known to play a role in the treatment of osteoporosis. However, the molecular mechanisms of this process remain unclear. This study aimed to investigate the effects of bovine CP compounds on the proliferation and differentiation of MC3T3-E1 cells. Methods Mouse pre-osteoblast cell line MC3T3-E1 subclone 4 cells were treated with bovine CP compounds. Cell proliferation was analyzed by MTT assays and the cell cycle was evaluated by flow cytometry scanning. Furthermore, MC3T3-E1 cell differentiation was analyzed at the RNA level by real-time PCR and at the protein level by western blot analysis for runt-related transcription factor 2 (Runx2), a colorimetric p-nitrophenyl phosphate assay for alkaline phosphatase (ALP), and ELISA for osteocalcin (OC). Finally, alizarin red staining for mineralization was measured using Image Software Pro Plus 6.0. Results Cell proliferation was very efficient after treatment with different concentrations of bovine CP compounds, and the best concentration was 3 mg/mL. Bovine CP compounds significantly increased the percentage of MC3T3-E1 cells in G2/S phase. Runx2 expression, ALP activity, and OC production were significantly increased after treatment with bovine CP compounds for 7 or 14 days. Quantitative analyses with alizarin red staining showed significantly increased mineralization of MC3T3-E1 cells after treatment with bovine CP compounds for 14 or 21 days. Conclusions Bovine CP compounds increased osteoblast proliferation, and played positive roles in osteoblast differentiation and mineralized bone matrix formation. Taking all the experiments together, our study indicates a molecular mechanism for the potential treatment of osteoarthritis and osteoporosis.

Abstract: In order to improve the anticoagulant function of Auricularia auricula, Auricularia auricula polysaccharide(AAP)was converted into its derivatives by the microbial fermentation method and then polysaccharide derivatives with stronger anticoagulant activity were prepared. The optimal conditions for fermenting the polysaccharide from A. auricula were examined and the in vitro anticoagulant activities of transformed and untransformed polysaccharides were compared. Response surface tests and an orthogonal experiment indicated that the best conditions for microbial conversion of AAP3 were an AAP3 concentration of 4.0 mg/mL, a ratio of substrate(AAP3)to donor(p-hydroxybenzoic acid)of 40∶1, and a pH of 6.0. Bacillus subtilis Bs-07 was inoculated and then placed on a rotary shaker(120 r/min), followed by fermentation for 48 h at 35 ℃.The conversion rate was found to be greater than 40%. The result of in vitro anticoagulant activity showed that the transformed polysaccharide improved activated partial thromboplastin time, prothrombin time, and thrombin time values and greatly enhanced anticoagulant activity compared to the untransformed polysaccharide.

Abstract: 为明确内生枯草芽胞杆菌Itb57菌株抑制烟草疫霉生长的机理,分别采用电镜扫描法、生化测定法和电导法研究了其对烟草疫霉菌丝形态及生理生化指标的影响。结果显示,经Itb57菌株发酵滤液处理的疫霉菌丝畸形膨大、分枝短粗,孢子囊的形成及萌发受到显著抑制,当发酵滤液浓度为50%时,抑制率分别为79.69%和70.85%;且与对照相比,处理组疫霉菌细胞壁主要成分碱溶性、碱不溶性和水溶性的β-1,3-葡聚糖含量分别降低了51.18%、42.56%和39.42%,β-1,3-葡聚糖合成酶活性降低了72.45%,DNA含量降低了14.64%;线粒体复合酶活性显著低于对照,其中复合酶Ⅱ活性降低了79.25%,菌丝处理液电导率升高。表明枯草芽胞杆菌Itb57菌株发酵滤液能减少疫霉细胞壁主要成分β-1,3-葡聚糖含量,破坏细胞膜的完整性,导致菌丝生长受阻或产生畸形,对烟草黑胫病的控制具有潜在的生防价值。
To understand how the Itb57, an endophytic strain of Bacillus subtilis, inhibite the growth of the tobacco Phytophthora parasitica, the impact of the bacterial fermentation filtrate on mycelium morphology, physiological and biochemical changes of Phytophthora parasitica var. nicotianae were studied with scanning electron microscopy and an array of biochemical and physiological assays. The results showed that treatment with 50% fermentation filtrate caused malformation of the mycelium with short branches, and significantly inhibited the formation and germination of sporangium by 79.69% and 70.85%, respectively. Main components of the pathogen cell walls, such as alkali soluble β-1, 3-glucan, alkali insoluble β-1, 3-glucan, and water-soluble β-1, 3-glucan content were reduced by 51.18%, 42.56% and 39.42%, respectively, compared to the control treatment. The activities of β-1, 3-glucan synthase was reduced by 72.45%, and the DNA content was also reduced by 14.64% in the pathogen. The enzyme activities of mitochondrial complexes were significantly lower than those of the control, and especially that the complex II enzyme activity dramatically reduced by 79.25%. Moreover, the conductivity of the P. parasitica mycelia increased upon treatment with the fermentation filtrate. The results suggested that the fermentation filtrate of strain Itb57 could reduce β-1, 3-glucan as the main content in the cell walls of P. parasitica, destroy the integrity of the cell membrane, repress the hyphal growth, and finally lead to malformation of hyphae. Therefore, it can be concluded that the endophytic Itb57 has the potential to be used as a bio-control agent in the control of tobacco black shank disease.

Abstract: Transcriptome reconstruction is an important application of RNA-Seq, providing critical information for further analysis of transcriptome. Although RNA-Seq offers the potential to identify the whole picture of transcriptome, it still presents special challenges. To handle these difficulties and reconstruct transcriptome as completely as possible, current computational approaches mainly employ two strategies: de novo assembly and genome-guided assembly. In order to find the similarities and differences between them, we firstly chose five representative assemblers belonging to the two classes respectively, and then investigated and compared their algorithm features in theory and real performances in practice. We found that all the methods can be reduced to graph reduction problems, yet they have different conceptual and practical implementations, thus each assembly method has its specific advantages and disadvantages, performing worse than others in certain aspects while outperforming others in anther aspects at the same time. Finally we merged assemblies of the five assemblers and obtained a much better assembly. Additionally we evaluated an assembler using genome-guided de novo assembly approach, and achieved good performance. Based on these results, we suggest that to obtain a comprehensive set of recovered transcripts, it is better to use a combination of de novo assembly and genome-guided assembly.

Background: To explore the hepatoprotective effect of Yigan mingmu oral liquid (YGMM) on isoniazid-rifampicin induced liver injury in rats. Methods: Total 38 SD rats were randomly divided into 6 groups including control group, model group, silymarin positive control group, and three YGMM treatment groups. Model group was administered intragastrically with INH (100 mg/kg) and RIF (100 mg/kg) for 14 days. Silymarin group and YGMM treatment groups were administered intragastrically with silymarin (100 mg/kg) and different doses of YGMM (1, 2.5, 5 mg/kg) 2 hours before INH and RIF administration from day 4 to day 14.Results: Rats were sacrificed 16 hours after the last day treatment to determine the activities of serum alanine transaminase (ALT), aspartate transaminase (AST) and alkaline phosphatase (ALP), as well as total bilirubin (TB) content. Oxidative stress was evaluated by measuring total superoxide dismutase (T-SOD) and malondialdehyde (MDA) levels. Histopathological changes in liver tissues were observed under an optical microscope by using hematoxylin and eosin staining. The mice?in model groups showed significantly (p < 0.05) increased levels in AST, ALT, ALP, TB and MDA compared to their control groups; and showed significantly (p < 0.05) decreased level in T-SOD. These changes were significantly (p < 0.05) reversed by the YGMM treatments in a dose-dependent manner. Hepatic pathological changes were attenuated or even reversed by silymarin or YGMM treatments. Conclusions: YGMM has a good hepatoprotective activity on isoniazid-rifampicin induced liver
