The volume of sewage increases as the population grows and the standard of living rises, and also varies in direct proportion to the volume of available water supply. Present1y(at the end of 1998), the sewage treatment ratio is 60%, and 85 facilities are woiking for sewage treatment While sewage treatment plant has been constructed in large cities and heavily industrialized cities, the most treatment plant employ one type of process, i.e. activated sludge process, which may not be desirable for some cities in economical point of view and also in terms of process optimization. Moreover, poor sewer systems resulted in lower strength influet than the designed strength. In this study, to develop a proper process for treating low strength sewage several existing sewage treatment plants were diagnosed. A continuously contacted sequencing batch reactor composed of pre-anoxic contact zone and intermittently aerated zone was operated for biological nitrogen removal. The removal efficiencies of organic matter (SCOD) and total nitrogen (T-N) were 89% and about 60% at the TCOD/T-N ratio as low as 6.0, respectively.

The environments of Korean financial markets after 1990s have been changing rapidly, The degree of competition has increased greatly by the liberalization of financial markets and the deregulation of financial institutions management. This increased competition in turn requires different management strategy. In the interest rate environment. the level and volatility of interest rate are higher than in other collntrips which have well developed financial markets. Therefore, management of interest rate risk exposure is very important for financial institutions to exist and keep an competitive edge in a changing environment. There are many possible ways to control interest rate risk of financial institutions. Option markets may be one possible alternative. But there are some limitations in option-based interest rate risk management. Instead of interest rate option, combination of interest rate options provide good hedging tool in controlling interest rate risk. In this paper, interest rate cap and inferest rate floor are analyzed with an emphasis on how this can be utilized in controlling the impact of uncertain and volatile financial market conditions.

In this paper swap-based asset and liability management is introduced with an emphasis on how the strategy can be utilized in controlling the impact of volatile financial market conditions. In recent years, swap markets have become one of the most popular and effective financial markets available to the manager's of financial institutions for controlling the interest rate sensitivity of their balance sheet positions. In a high and volatile interest rate environment of Korean financial markets, management of interest rate risk exposure of financial institutions is very important to keep an competitive edge. Opportunities in off-balance sheet activities amy be one possible way to provide yield enhancement while controlling risk over traditional strategy, such as duration-based strategy.

Multimedia synchronization techniques are an important field in the implementation of multimedia applications. We study multimedia synchronization schemes and suggest an ac-celeration-based multimedia synchronization scheme. In this scheme, if the slave device of the receiver detects asynchrony between master and slave media, the slave device ac-celerates or decelerates slave media presentation speed.

2% dorzolamide solution (Trusopt ^TM) is commercially available recently, and we applied this new agent to glaucoma patients to assess the effect on the korean glaucoma patients. We prescribed 2% dorzolamide solution three times a day for the patient who had not shown a significant fluctuation of intraocular pressure (IOP) under the same regimen at least 4 weeks interval. We assessed the IOP of the 30 eyes of 18 patients before and 4 weeks and 8 weeks after initiation of this agent retrospectively. The patients were divided into 3 groups ; group 1 composed of 3 eyes of 2 patients who had not used any ocular hypotensive drugs before this study. Group 2 was composed of the patients who had used more than 1 ocular hypotensive solutions, and 2% dorzolamide was added to their regimen. Patients who had used more than 1 ocular hypotensive agents including oral acetazolamide was classified as group 3, and one of their regimen was substituted to 2% dorsolamide solution. The mean IOP of group 1 was decreased by 27.3% at 4 weeks and 21.6% at 8 weeks after initiation of new drug. In group 2, there was an additional decrement of mean IOP by 19.0% at 4 week and 23.6% at 8 weeks. And in group 3, there was a decrement of mean IOP by 19.4% at 4 weeks and 20.9% at 8 weeks for the 3 eyes for which we substituted pilocarpine solution with dorzloamide. In the 4 eyes to which we exchanged beta-blockers with dorzolamide, the IOP decreased slightly by 9.9 and 6.3% respectively. In the 11 eyes for which we discontinued acetazolamide and used dorzolamide, the IOP was decreased by 7.1% at 4 weeks, but the IOP was increased by 13.0% at 8 weeks after substitution. Although we need more long term study with more large numbers of subjects, from the above result we can expect hypotensive effect when we use this drug as a single regimen, and additional hypotensive effect when we add this solution to other regimen. And this drug may substitute pilocarpine or beta-blocker effectively, but we should be careful when we are trying to replace the acetazolamide with dorzolamide.
