In this paper, the development of the extended kalman filter(EKF) which is based on Koreasat-3 bus system is introduced and the design result is shown through the simulation. Especially to determine the filter gains for accurate estimation, there is assumed that initial estimated parameters are not changed. But although the satellite performs the attitude control by 2Hz, it is verified that the EKF is running rightly using the changed filter gains. Also some cases are considered using the simulation : with each bias for 4-axis gyro and with gyro each axis failure. It is verified that the designed filter can be used as the back-up about gyro failure.

The high prices and lack of information for satellite images prevent researchers from studying remote sensing and most non-professional people can't have the simple and easy solutions for the manipulation of satellite images. 'Satellite Imagery Information Management Center'(SIMC) project which is promoted by ETRI (Electronics and Telecommunications Research Institute) from 2002 to 2005 in Korea have the purpose to provide the satellite images freely to the public domain and the solutions for the above mentioned problems. Our project have the following five systems; Data Acquisition System, Data Preservation System, Integrated Solution System, Technology Development System, Operation Plan System. Data Acquisition System collects the satellite images such as LANDSAT, IKONOS, etc. Data Preservation System consists of database which registers the diverse satellite images. Integrated Solution System gives the user of public domain for the web service which search, order and transfer the satellite images. Technology Development System has the many processing technologies for the satellite images. Finally, the Operation Plan system has the role to plan the future of our SIMC project. In this paper, we will give the result of SIMC Project for each five systems during the fast four years from 2002 to 2005.

Users of computer interfaced with the LAN use the same printer with time sharing. Alternatively, Hey use the multi-user printer interface to print in the office which can't have LAN system due to the great expenses. Otherwise they have to connect directly moving the printer to computer. In this papaer, we present a new printer interface equipment which can interface a printer and multi computers through wireless using the radio frequency of about 430MHz. The tranceivers of the equipment consist of two part: one part is installed in parallel port of computer and other part is installed in Centronix port of printer. Their maximum data rate is 9600bps and the communication area is about 50 meters in best case.

The purpose of this research was to examine the level and trends in household clothing expenditure in Korea. Raw data sets produced by the National Statistical Office from the Family Income and Expenditure Survey from 1991 to 2004 were used to support time-series and cross-sectional analyses. The clothing expenditures decreased severely and quickly during the economic crisis of late 1997 through 1998, then increased slowly after the economic crisis until 2003, only to slightly decrease again in 2004. The ratio of clothing expenditure to total household expenditure decreased from 8.03% in 1991 to 5.11% in 2004. This decrease in relative clothing expenditure was greater in the lower income group than in the middle and high income groups. Clothing expenditure patterns were unique and differed from other household expenditures. Although the economic crisis in the late 1990s affected Korean consumers' clothing expenditure, clothing expenditure patterns showed a more fundamental and structural change from 1991 to 2004, with the overall decrease in such expenditure resulting from the concurrent increase in educational and information-communication related expenditures. Clothing expenditure was shown to be luxurious through cross-sectional analysis, but necessary through time-series analysis.

Key establishment protocols are fundamental for establishing secure communication channels over public insecure networks. Security must be given the topmost priority in the design of a key establishment protocol. In this work, we provide a security analysis on two recent key establishment protocols: Harn and Lin's group key transfer protocol and Dutta and Barua's group key agreement protocol. Our analysis shows that both the Harn-Lin protocol and the Dutta-Barua protocol have a flaw in their design and can be easily attacked. The attack we mount on the Harn-Lin protocol is a replay attack whereby a malicious user can obtain the long-term secrets of any other users. The Dutta-Barua protocol is vulnerable to an unknown key-share attack. For each of the two protocols, we present how to eliminate their security vulnerabilities. We also improve Dutta and Barua's proof of security to make it valid against unknown key share attacks.
