With the global population of informatization and digitization, network technology is playing a very important role in people's lives. The role of wireless LAN applications is especially significant. People's daily lives and work are no longer confined to paper or wired connection, but gradually extend to the use of radio. Although it brought a lot of convenience to people's lives, wireless LAN security problems also frequently occurred. This paper mainly aims to analyze the security risk and at the same time offer some preventive measures.Wireless LAN mainly bases on information technology and high-tech office technology as the basic starting point, whose main function is to make all kinds of information data transmitted rapidly in the network to ensure high-speed and convenient,work efficiency and realize work automation and rapidity. But without exact security for the virtual network, many security issues emerged. So the primary issue in wireless LAN now is to strengthen the security of data information. This paper first analyzes the security problems of WLAN, then put forward some prevention measures. © (2014) Trans Tech Publications, Switzerland.

In Everyday life, vegetables play an integral role in people three meals a day without it, which determines the liquidity of vegetables is very large. However, their characteristics and vegetables logistics level of logistics stage lead to the existence of many problems existing in the logistics of fresh vegetables, which greatly affects the speed and quality of vegetable circulation, thereby affecting the quality of people eat vegetables. This paper conduct discussion on major problems in logistics and vegetables, and try to make some reasonable solution. © (2014) Trans Tech Publications, Switzerland.

The contents, statistics, composition and challenge of agriculture-information are discussed in this paper. The influence of agriculture-information on the intensive growth of agriculture is analyzed empirically, which indicates that information has become an important production factor. Though without certain form, information promotes intensive growth of agricultural economy by increasing the quality of production factor including labor, land and capital. The mechanism in which agriculture-information influences the intensive growth of agricultural economy is promoting the accumulation, structure studied theoretically, which includes optimizing and of agriculture; accelerating agricultural knowledge technological progress and extension; creating transparent information environment to optimize the allocation of resource; promoting scientific management of agriculture and civilization of rural human resource; strengthening the function of agricultural cooperative organization and spurring on the improvement of agricultural economic environment. © (2014) Trans Tech Publications, Switzerland.

K-means algorithm is a traditional cluster analysis method, has the characteristics of simple ideas and algorithms, and thus become one of the commonly used methods of cluster analysis. However, the K-means algorithm classification results are too dependent on the choice of the initial cluster centers for some initial value, the algorithm may converge in general suboptimal solutions. Analysis of the K-means algorithm and particle swarm optimization based on a clustering algorithm based on improved particle swarm algorithm. The algorithm local search ability of the K-means algorithm and the global search ability of particle swarm optimization, local search ability to improve the K-means algorithm to accelerate the convergence speed effectively prevent the occurrence of the phenomenon of precocious puberty. The experiments show that the clustering algorithm has better convergence effect. © (2014) Trans Tech Publications, Switzerland.

In order to reduce costs and improve crop yields effectively, a greenhouse environment monitoring system based on ZigBee and GPRS technology is designed. In the system, ZigBee wireless sensor module is used for data acquisition of soil moisture, precipitation, nitrogen concentration, temperature and barometric pressure data etc. The information is sent to a remote monitoring center through GPRS, Instructions is regulated and take corresponding measures according to the received information. The system can collect and monitor the parameters of the greenhouse environment at a real time. This has important implications for the development of agriculture automation and agricultural production levels. © (2014) Trans Tech Publications, Switzerland.

As the wide application of computer and information sharing, database security and privacy of data become a research hotspot. First this paper analyzes the security threats the database face, from internal personnel errors, configuration, social engineering, and not patched vulnerabilities four aspects. And then it expounds database system security technologies that are database authentication, access control and audit. Finally, this paper introduces the privacy protection of the database. It hopes to provide the certain reference significance in improving the database security and privacy protection technology. © (2014) Trans Tech Publications, Switzerland.

Base on the existing disadvantages of the conventional three-stage charging method, the paper provided a intelligent and dynamic Charging ideal with a fuzzy control ideal based on J. A. Mas 's law and the characteristics of lead-acid battery charging. A fuzzy controller design achieved according to the empirical data of charging control and the system's hardware and software realized with PIC6014 microcontroller as the core. Experiments show: The intelligent and dynamic charging systems based on fuzzy control enable the charging current to achieve real-time changes according to the acceptable current size of the battery, enhanced the energy efficiency and avoid over-charge and less-charge effectively, realized efficient, fast and safe charging. © (2013) Trans Tech Publications, Switzerland.
