      • 2% Dorzolamide 점안액을 사용한 녹내장환자에서의 안압 변화 : A Clinical Study

        김창식,조항진,이강일 충남대학교 의과대학 지역사회의학연구소 1997 충남의대잡지 Vol.24 No.2

        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.

      • 옵션형태의 이자율계약을 이용한 금융기관의 이자율위험관리

        김흥식 동국대학교 경주대학 1996 東國論集 Vol.15 No.-

        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.

      • SWAP을 이용한 金融機關의 ALM전략에 관한 연구

        金興植 동국대학교 경주대학 1995 東國論集 Vol.14 No.-

        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.

      • 詩의 時間性 硏究

        朴沆植 圓光大學校 1980 論文集 Vol.14 No.1

        Paul-Ambroise Valery said that language had two functions; one is to convey mea-nings and the other emotions. Among those, we should take the latter in order to co-nstruct the pure Poetry. And also he maintain that we must exclude all the prosaic elements in poetry. Whereever does the emotion come from in this case? Without question,it comes from the transmission for readers by virtue of reappearance of the emotion we have experienced. What we have ordinarily experienced is of course made up of by sound & color and conscious content which is immanent and unified perception. That is in itself looking, listening and perception. If we appreciate the beauties of sound & color,how lucky enough it is. Therefore the problems of poetry and the nature of time are raised. They serve as a mysterious role. This study aims at describing the nature of time and in turn the time of natural science, philosophical time, the kind of time and finally the poetry which has physical time. Especially among the kinds of time, there are three; physical time by Newton's method of Sir Issac Newton, historical time (Sein und zeit) of Martin Heidegger and psychological time of Henmri Louis Bergson. In the case of physical time, the relationship between poetry and time was concretly illustrated and also in the case of psychological time, the function of the time in poe-try was slightly described at chapter 6. "the time of Buddhist Literature". However, The way of characterizing the psychological time in poetry remains as the prospective subject.

      • 발포 유기질 단열재의 경시특성에 관한 연구

        조항선,김우식,염경호,남궁식 연세대학교 산업기술연구소 1984 논문집 Vol.16 No.1

        The aging properties of cellular plastic insulations(EPS,PUF and UFF) were investigated by varying temperature, relative humidity and time. The time aging properties were changed with in 10 - 12% of initial properties at high temperature(above 318K) and relative humidity (above 90%). The amount of HCHO gas release from UFF was increased as temperature and relative humidity increased, and HCHO release rate was decreased exponentially with time.

      • 詩속에 들어 있는 時間의 諸樣相 : 心理的 時間을 中心으로 Various aspects in the center of the being time

        朴沆植 圓光大學校 1982 論文集 Vol.16 No.1

        Time was changed according to the way of thinking of human. However if we mentioned its kinds we could say that three kinds of time are the going time, the coming time and the being time. Among these the going time is the exactly objective time which Newton proposed and the coming time is the presented time Martin Heidegger proposed in his "Existence and Time" and also the being time is the intutive time Heri Bergson proposed. This study discusses the kind of poems which expressed the going time, the coming time, the being time and the results of these existed in these poems. All poems expressed the giong time are those of the technician. Therefore we can not find the depth of though and his view of life or the word. But shows an interest to the readers only. Poems expressed the coming time was found in the revolutionary written by the poets who loved his country and thus these have the devotion to his country and to his people as the central idea. Therefore we can say that these poems are laid on more high level of the mental situation than those expressed the going time. Poems expressed the being time was found in the those written by the nations leader or a saint and Buddhist priest. These are mainly the poems written after attaining enlightenment. Consequently, I was conclued that these poems are laid on the most high level of the mental situation. It goes without saying that poems which was included the eternity, infinity and joys give us the largest consolation.

      • 하수처리의 문제점과 연속접촉회분식 반응조를 이용한 고도처리

        신항식,남세용,이상형 경산대학교(대구한의과대학) 1999 環境硏究 Vol.4 No.1

        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.
