An RFID application needs to collect product's information scattered over the RFID network efficiently according to the globalization of RFID applied enterprises. To be informed of the stock status of products promptly in the supply chain network, especially, it is necessary to support queries that retrieve statistical information of tagged products. Since existing RFID network does not provide these kinds of queries, however, an application should request a query to several RFID middleware systems and analyze collected data directly. This process makes an application do a heavy computation for retrieving statistical information. To solve this problem, we define a new Distributed Continuous Query that finds information of tagged products from the global RFID network and provides statistical information to RFID applications. We also propose a Distributed Continuous Query System to process the distributed continuous query efficiently. To find out the movement of products via multiple RFID systems in real time, our proposed system uses Pedigree which represents trade information of items. Our system can also reduce the cost of query processing for removing duplicated data from multiple middleware systems by using Pedigree.

With the explosive proliferation of smart devices that may be connected to the fast Internet, virtual desktop interfaces(VDI) are being implemented in enterprises allowing employees to work anywhere anytime in the same technological environment. As this kind of systems are intended to raise the work performance, a research model is constructed from the review of research literature on service quality and work design. The model consists of VDI system service quality (ubiquity, availability, compatibility, security and ease of use), system satisfaction, task performance and job satisfaction. As VDI is designed as a support system for cooperative work, the task interdependence adopted from the work design theory is postulated here as moderating the effect of user satisfaction on task performance and job satisfaction. 147 data points were collected by a survey of VDI users in a global firm and subjected to PLS analysis. Interestingly, ubiquity and compatibility seem to be not statistically significant for user satisfaction while availability, security and ease of use of VDI system are statistically significant. Task interdependence is found to be a relatively strong mediator between system user satisfaction and task performance, however, interestingly, the coefficient come out as negative. This may indicate that the influence of VDI user satisfaction on task performance would not be high in highly interdependent tasks. Considering that VDI is intended for supporting 'interdependence' in cooperative work, this finding is a bit surprising. In-depth discussions are made in the discussion followed by future research directions.

Space technology is a core technology which is emerging as the most competitive industry in the 21st century. However, it is said that private enterprises may have some limitations to run the space business independently because the space industry requires not only to enormously spend the amount of investment at the beginning stage of business but also to have lots of difficulties to get the amount of investment in the short period of time. Therefore, the advanced countries of having the space industry such as America, Japan, France and so on have been developing the space technologies through the help of their governments to some level at the beginning stage of business. Korea established the space development promotion law in 2005. Also Korea has been making efforts to correct the national space development middle and long term basic plans. However, while Korea becomes the 8th economic country in the world, Korea does not have a large enterprise which has ability to supply the domestic satellite demands, and to export satellites to foreign countries by developing satellites without having any help from foreign companies. Therefore, this paper described the activating scheme of satellite industry to efficiently carry out the Korea's space development mission, and to enforce the global competitive power.
