TMA clathrate that is used as PCM of low temperature thermal storage system in this research creates hydrate crystallization at higher temperature than pure water, and its application is expected as PCM because of comparatively big latent heat without phase separation phenomenon. Ethylene Glycol is used as additive and evaluated experimentally for the purpose of the improvement in subcooling of TMA clathrate. In view of the results so far achieved subcooling is improved, the running time of the refrigerator is reduced. Thus the results are expected to use for the increase of coefficient of performance of low temperature thermal storage system in the building.

Agents have become very popular in the last six or so years. Agent technology has a large part to play in facilitating general information retrieval on the Internet. More recently, the capabilities of agents have been applied to Electronic Commerce. To be univrersal Electronic Commerce, Customer buys goods by internet and choose the providers widely. but It's came into the question that haw can contact provider for cheap goods. It says that Electronic Commerce Agent. Among Electronic Commerce Agents, if agent supply goods information for- cost, the agent be called Comparison Shopping Agents. In this paper, we designed and implemented a Comparison Shopping Agent for music disk searching. Agents has insufficiencies Agents can't retrieve information in web page is made by CGI program. If Agents want to get the information for Comparison Shopping Agent, they can't execute the work. Because shopping-malls are made by CGI program. In this paper, we propose that usage of FORM-tag for a local database.

도병훈,김신우,오종택,손종원,하상우,이응갑,장현하,이종명,김능수 대한감염학회 2005 감염과 화학요법 Vol.37 No.2

목적 : 본 연구는 뇌실외 배액술을 시행한 신경외과 환자들에서 뇌실염 발생 빈도, 원인균주와 감수성 추이 및 경험적 치료로 사용되는 항생제인 ceftazidime과 vancomycin의 적절성 여부에 대하여 조사하였다. 재료 및 방법 : 2000년 12월부터 2003년 10월까지 EVD를 시행한 경북대학교병원 신경외과 입원환자 340명 중 뇌실염이 발생한 39명을 대상으로 후향적으로 조사하였다. 결과 : 340명 중 39예 (11.5%)에서 뇌실염이 발생하였고 이들 가운데 4명이 뇌실염과 연관하여 사망하였다(10.3%). EVD 시행일로부터 뇌실염 발생까지는 평균 8.4일이었다. 원인균은 33예(87.1%)에서 확인되었으며 Aci-netobacter (19예, 45%), methicillin-resistant coagulase negative Staphylococcus (9예, 22%), methicillin-resistant Staphylococcus aureus (9예, 22%) 등의 순이었다. 가장 많이 동정된 Acinetobacter 19예 중에서 8예(42.1%)가 ceftriaxone에 내성을 보였으며 현재 경험적으로 널리 사용되는 ceftazidime에 대해서는 11예중 3예(27%)가 내성을 보였다. 결론 : 최근 EVD 시행과 관련된 뇌실염 뇌실염 최근 그람음성 non-fermenter 특히 Acinetobacter에 의한 경우가 증가하고 있으며, 이들 그람음성 non-fermenter는 현재까지 경험적으로 사용되는 ceftazidime에 점차 내성을 보이고 있다. 경험적 치료제에 대한 성공률을 높이기 위해서는 각 병원별 내실염의 원인균주의 감수성에 대한 검사가 필요하겠다. Purpose : To investigate the etiologic microorganisms of external ventricular drain (EVD)-related ventriculitis and the appropriateness of using ceftazidime and vancomycin as an empiric therapy in neurosurgical patients with EVD-related ventriculitis. Materials and Methods : Retrospective analysis of 39 patients with EVD-related ventriculitis among 340 neurosurgical patients to whom EVD had been placed during December 2000 and October 2003 at Kyungpook National University Hospital. Results : Thirty-nine EVD-related infections (39/340, 11.5%) occurred and the attributable mortality rate was 10.3% (4/39). The average duration from the ventricular catheter placement to the development of ventriculitis was 8.4 days. All patients with EVD infection had fever and 89.7% (35/39) of the patients showed nuchal rigidity. The positive culture rate in CSF was 87.1% (34/39) and the frequency of individual organism is as follows : Acinetobacter 45% (19 cases), methicillin-resistant coagulase negative Staphylococcus 22% (9 cases), methicillin-resistant Staphylococcus aureus 22% (9 cases), Enterococcus 5% (2 cases), Streptococcus pneumoniae 3% (1 case), non-fermenting gram-negative bacilli 3% (1 case). The polymicrobial infection rate was 15.4% (6/39). Among 19 cases of Acinetobacter infection, 42.1% (8/19) of the strains showed resistance to ceftriaxone and 15.7% (3/11) to ceftazidime. However, all cases were sensitive to meropenem. Conclusion : These findings show that the major etiologic organisms causing EVD-related ventriculitis have recently changed to Gram-negative non-fermenters, especially Acinetobacter. Because Gram-negative non-fermenting rods resistant to ceftazidime are increasing, an immediate change from ceftazidime plus vancomycin, the widely accepted empiric antibiotic therapy, to meropenem plus vancomycin should be considered when clinical symptoms and signs show no improvement or even deterioration.

Acute myocarditis complicating coronary vasospasm after smallpox vaccination is very rare complication that can be generally developed within less than 30 days after vaccination. Clinically and biochemically, this disorder is often mimic and highly suggestive of acute myocardial infarction. We report 21 years old man that had a history of a smallpox vaccination 3 weeks ago and prodromal symptoms(fever, malaise etc) a few days ago. hIe visited to our hospital because of abrupt onset of severe substernal chest pain, dyspnea and diaphoresis. At admission, electrocardiography was ST elevation in lead Ⅰ, aVL, V4, V5, and V6. The CK-MB level was 68 U/L, LDH level was 760 U/L, Troponin-Ⅰ was 24.64 ng/㎖, and Troponin-T was positive. 2D-echocardiograpy was normal left ventricular function, Clinically we presumed this disorder as acute myocardial infarction and we promptly performed the coronary angiography and revealed focal spasm in distal left coronary artery territory without critical stenosis in both coronary arteries. We diagnosed this disorder as coronary vasospam complicating acute myocarditis that is different with acute myocardial infarction, and we prescribed nitroglycerin and nifedipine. After discharge, he is now well without any symptoms and has been following up monthly at our outward department for 6 months.

중추에서 Prostaglandin계가 Renin-angiotensin System에 미치는 영향

Role of prostaglandins on the renin-angiotensin system in the central nervous system was examined in normotensive and 2-kidney, 1 clip (2K1C) hypertensive rats. The experiment was done under thiopental (50 ㎎/㎏, IP) anesthesia. Captopril and indomethacin were injected into the right lateral cerebral ventricle. Arterial blood pressure and heart rate were recorded from the femoral artery. Intracerebroventricular (ICV) captopril (1 ㎎) caused a decrease in mean arterial pressure in both normotensive and 2K1C hypertensive rats. The depressor response to captopril was more sensitive in hyper-tensive rats than in normotensive rats. Indomethacin treatment (ICV, 200 ㎎) altered the depressor response to captopril neither in normotensive nor in hypertensive rats. These results suggest that the cardiovascular effect of renin-angiotensin system in the central nervous system may not be mediated via prostaglandin systems in normotensive and 2KlC hypertensive rats.

Community dynamics of phytoplankton and primary productivity have been investigated bimonthly from February 1997 to December 1997 in the coastal area around Moonsom of the southern Cheju Island, which is well-known for soft coral habitats in Korea. Average water temperature was 18.5℃ , being stratified from May to September by the seasonal thermocline, while vertically homogeneous in the winter. Euphotic depths ranged from 18.9 m to 45.9 m (average 33.7 m). Chlorophyll α concentrations varied from 0.02 to 0.92 ㎍ · ℓ-1 Standing crops of phytoplankton ranged from 2×103 to 3.9×105 cells · ℓ-1, showing a peak only in the spring. Diatoms occupied 67.5% of the total standing crops, while phytoflagellates, dinoflagellates and others 24.3%, 7.1% and 1%, respectively. However phytoflagellates and dinoflagellates were predominated with 36.6% and 38.7% in June, respectively. There was four dominant species in the study area. Chaetoceros sociales Lauder was dominant species from December to April, Prorocentrum micans Ehrenberg in June. In August, Chaetoceros socialis Lauder dominated in inshore but Paralia sulcata (Ehrenberg) Cleve in offshore. In October, Skeletonema costatum (Greville) Gran dominated the whole area. Daily primary productivity varied from 32.3 to 364.9 mg C · m-2 . day-1 (average 180.7 mgC · m-2 . day-1). Contribution of nanoplankton (<20 ㎛) to daily primary productivity was very high, accounting for 28.0-82.8%. Annual primary productivity is estimated 65.97 gC · m-2 ·yr-1, which is lower than those of the coast of Yellow Sea and the southern waters. Nanoplankton seemed to adopt higher irradiances with Ik values of 190-1,000 □· m-2·s-1 (mean 526.7 □ · m-2·s-1) than total phytoplankton with 140-850 □ ·m-2·s-1 (mean 466.7 □· m-2·s-1).

The College of Engineering was specialized to have a sole function for supplying technical high school teachers in 1977 and referred to as the College of Industrial Education according to the Government's policy. The economic impact mainly due to the oil-crises caused a severe problem to this college, namely discrepancy of supply to demand scale. Accordingly the number of student enrollment was to be fluctuated from 479 in 1979 through 800 in 1979 and 900 in 1980 to 430 in 1981. And the engineering departments have been attached to this Engineering Education College since 1981. These circumstanses met singnificant inefficiency in facility operation. This program aims at providing an overall relocation of the college facilities and preparing the practical system to make the joint-operation possible taking into account circulation, academic stream, budget, maintenance, etc. However this study could not get optimal spacing but some trade-off, considering the current situation.
