Trying to give an overview of home informationization accelerated by the information age, the main purpose of this research is to suggest a guide for home Economics to adjust to the era. While the informatinization in home provides convenience and plays a major role to improve the quality of the life there are still many problems to be reflected on. First of all in order to utilize a variety of information devices it is needed that technical index related to home management such as home information device index and the expenditure on information is studied. Secondly, it is needed to predict possible home life style in the future and build up the ability to adjust to the change. Therefore, in the field of home economics, developing programs to offer the better chance of education on home life and culture, values, relationships, capability to enhance home life etc, is in urgent need of reflection.

This study reviews an overview of the current tax support system for venture company and provides the directions for developing tax support system related policy for the venture company in Korea. The tax authority provides a supporting directions of venture company in three ways: a financing viewpoint, a technical and manpower viewpoint, and the location viewpoint. And the supporting system for venture company is devide into tax support system through tax laws and support system through other law. The requirements of receiving tax support for venture company are a venture company, a small and medium company, a newly starting firm, and so forth. To mitigate the restriction imposed by the current tax law on venture company encourage venture activities in Korea.

Classical membrane processes like microfiltration (MF), ultrafiltration (UF) and reverse osmosis (RO) are being applied in the last years more frequently in environmental and effluent process problems. Newer technologies and developments like pervaporation (PV) and gas sepaxation (GS) recently found commercial applications in the treatment of waste waters and gas streams. The incentive here is either the clean-up from organic components to comply with federal emission regulations or the recovery of the organics for economical reasons. Processes still in their development stage are combinations of chemical reactions with membrane processes to separate and treat $SO_x$ and $NO_x$ laden waste gas streams in the clean-up of stack-gases. In this paper we will first give a short overview of the more recent developments in MF, UF and RO. This is followed by a closer look on newer technologies applied in environmental problems. The applications looked at are the recovery of organic components from solvent laden gas streams and the separation of organic volatiles from aqueous waste waters via pervaporation. Technical solutions, the advantages and disadvantages of the processes and. where possible, cost estimations will be presented.

Over the years of decades, the memory technology has progressed a long, marble way. As we have evidenced from the Intel’s 1Kb DRAM in 1970 to the Gigabit era of 2000’s, the road further ahead towards the Terabit era will be unfolded. The technology once perceived inconceivable is in realization today, and similarly roadblocks as we know of today may become trivial issues for tomorrow. For the inquiring mind, the question is how the “puzzle” of tomorrow’s memory technology is pieced-in today. The process will take place both in evolutionary and revolutionary ways. Among these, note-worthy are the changes in DRAM architecture and the cell process technology. In this paper, some technical approaches will be discussed to bring these aspects into a general overview and a perspective with possibilities for the new memory technology will be presented.

Many modern guided weapon systems employ sophisticated target sensors as well as powerful computing systems. Due to such advanced features, they are required to achieve better guidance accuracy, and at the same time other guidance objectives for better weapon effectiveness and survivability. In this paper, we overview some of the technical considerations in such advanced guidance algorithm development, and briefly look at some related research works. More specifically, we discuss impact angle control, time-varying nature of the guidance system, time-to-go estimation, guidance loop stability, effect of autopilot lag and physical limitations in control variables, parasitic paths in guidance loops, etc. We also briefly look at some advanced concepts such as integrated guidance and control loop design, target adaptive guidance, guidance law development based on dual control concept, and terminal evasive maneuver.
