Abstract: The competition and symbiosis relation of minor enterprises results from their active participation and other factors. The main motivations of their symbiotic development are to integrate different resources of relavant enterprises, share benefits and risks, promote continuely rapid development. In network economy era, cooperative symbiosis is playing an important parts in enterprise strategic management and innovation.

Abstract: While approval for MBO of large-scale enterprises has been suspended, MBO of the state-owned SMEs has set off a new round of MBO wave. Chinese primary state-owned and collective SMEs unify management rights and ownership through the implementation of MBO, with property rights being clear to the natural person of the management level and the reform being of certain spontaneity. However, the state-owned SMEs have such widespread problems as unperfected law system, narrow financing channels and inadequate information disclosure in the process of implementation. Based on the status, problems and cause analysis of implementation of MBO in Chines state-owned SMEs at this stage and aiming at the law, financing, pricing, information disclosure and other issues within, this paper puts forward countermeasures and suggestions related to further improving MBO of Chinese SMEs.

Abstract: Positions and roles of sports in treatment of children simple obesity are expatriated .Basic contents of exercise prescription are discussed from items,intensity and time of sports.In order toprevent and to cure the obesity effectively,people should keep on physical exercise regularly.

Abstract: Based on the study on the literature, combined with interviews, this paper theoretically proposed four dimensions of the guanxi structure among colleagues in the background of Chinese culture (emotional, instrumental, obligations and face.) Through the data of 611 valid questionnaires from enterprises with different sizes and natures, the models of guanxi structure between colleagues are obtained ,which have Chinese cultural characteristics.Through regression analysis, we find that the guanxi between colleagues has a positive influence on individual job performance, but the guanxi does a different direction of the impact in sub-domains of job performance from the sub-domains of coworker guanxi, and the influences are also different.

Abstract: In this study, multiple eigenvalues detection model has been put forward and empirical analysis and comparison between logistic regression model and multiple eigenvalues detection model has been conducted in the same sample on the basis of overall data. The results have showed the characteristics of accuracy, stability or extensive adaptability of multiple eigenvalues detection model in detecting false accounting information.

Abstract: Strauss believed that modernity has peaked after three waves. The third modernity wave started from Nietzsche and peaked at Heidegger. As the top of modernity, there are four characteristics of the third wave: historical concept of Radical Historicism, existential experience of pessimism, ethical ideas of Vitalism, Fascism ethical inception. They have composed of the deepest crisis of modernity.

Abstract: In recent years, the robot development has been fast expanding to many areas such as entertainment, home task, security, medical care, etc. Accordingly, this paper proposes a simple but reliable robot communication interface and local-loop control system based on RS232 and 8051 microprocessor, suitable use for various kinds of robot control. In this proposed scheme, the robot action commands stored in the database using C++ Builder can be transmitted from the Command-Transmission Microprocessor (CTM) and then received by the individual authorized Action-Processing Microprocessor (APM) via RS232. Real-time implementation results are presented to demonstrate the effectiveness of the proposed approach in term of robust, simple, flexible and efficient performance.

Abstract: Since the past years, the microprocessor (8051) has been still playing an indispensable role as a controller in industry applications because of fast executing process, low-cost, small size and low power consumption, etc. It, however, usually lacks of long distance transmission, graphical interface and vision. On the other hand, VB is now a very popular software package for graphical interface design due to easy exploring and low price. Combining both superiorities as above, this paper develops a remote visional microprocessor-based monitoring and control platform using VB graphical interface. The nearby PC (server) can collect real-time sensing signals from the 8051 through RS232 and transmit it to remote PCs (client) for on line monitoring mechanism via Internet. Also, the client can send the control signals to the server and thus control the 8051. The real-time case study for feeding care in the Pet House is provided to verify its well performance and remote Web-based capability in term of fast, simple and robust performance.

Abstract: In the pervasive computing environment, the users interact with the system through various terminals. How to adjust application interface according to the characteristics of terminals is very important in the pervasive computing system. In order to solve the interface diversity of pervasive terminals, an interface adaptive framework based on SVG is proposed. The framework adopts the hierarchical structure of separating interface and processing logic. By constructing the abstraction function mode of application, a uniformly SVG-based terminal interface is generated for different terminals. The simulation result shows that the framework has better practicability.

Abstract: Riser vortex-induced vibration (VIV) has been the outstanding problem affecting the normal safe operation in offshore oil exploitation. In this paper, based on computational fluid dynamics, a three-dimensional large eddy simulation (LES) numerical model was used to calculate the flow fields of unsteady flow around marine riser with different approaching flow velocities. Then streamlines, velocity and vorticity contours, drag and lift coefficients in different conditions were obtained. Simulation results indicate that the flow properties in different depth display obvious difference, which present complex three dimensional characteristics with interacting. It is thus clear that flow around marine riser can not be regarded as plane potential flow simply. The results also show that with larger approaching flow velocity, lift coefficient amplitude is bigger and frequency is higher, which is easier to result in vibration. Our approach may provide some references for safe design and engineering practice of VIV controlling of marine riser.
