Geographic Information System(GIS) has become an essential tool for making efficient interaction with both natural and artificial envirionment. Currently, it is being used on an inteligent tool in many device like the personal digital assistant(PDA) and the cellular phone and so on. However, these devices show very low performance comparing to a personal computer(PC). These devices(PDA, celluar phone) posses a less powered device profile. The less powerful hardware make these devices in capable to handle GIS based large spacial data. In this paper, we propose a new concept of multi-tier GIS oriented architecture to improve the data transfer performance providing only the necessary information required by the user using semantic filter.

In the shortest period of time, we achieved both industrialization and democratization. We also achieved good performance in health care sector. Whole population are covered by health insurance since 1989 and health outcomes, such as infant mortality, life expectance show good level. However, health care system has several problems, rapidly increasing rate of health care expenditure, dissatisfaction of both consumers and suppliers. Current health care system does not reconcile with market competition principle. Causes of these problems originated from 1977 paradigm which was formed to expand health insurance to whole population within short period. Dominant assumption of 1977 paradigm is to assure equitable access of health care by government's command and control. We urgently demand to reform the 1977 paradigm to suitable in 21th century. Our economy entered into a road to advancement. We have concerns how President Lee's administration reform health care system to harmonize with economic development and to achieve advancement in health care sector.

A hard disk, which can be classified as an external storage is usually capacious and economical. In spite of the attractive characteristics and efforts on the performance improvement, however, the operation of the hard disk is apparently slower than a processor and the advancement has also been slowly conducted since it is based on mechanical process. On the other hand, the advancement of the processor has been drastically performed as semiconductor technology does. So, disk I/O sub-system becomes bottleneck of computer systems' performance. For this reason, the research on disk I/O sub-system is in progress to improve computer systems' performance. In this paper, we proposed multi-level LRU scheme and then apply it to the computer systems with buffer cache and disk cache. By applying the proposed scheme to computer systems, the average access time to disk blocks can be decreased. The efficiency of the proposed algorithm was verified by simulation results.
