Background: Non-variceal upper GI bleeding (NVUGIB) is a common medical problem that has signifi cant association with morbidity and mortality. Angiographic detection and subsequent transarterial embolization (TAE) is a primary treatment option when medical and endoscopic treatments fail. We investigated clinical factors that could affect the success of the angiographic detection and prognosis after TAE in patients with NVUGIB refractory to endoscopic therapy. Methods: A retrospective analysis of the clinical data was done in patients with failed endoscopic treatment who underwent angiography for the treatment of acute NVUGIB between May 2002 and May 2013. Patients were divided into detection or non-detection groups according to the presence of bleeding stigmata in angiographic fi nding. Rebleeding defi ned as subsequent bleeding event within 7 days and mortality within 30days were analyzed as outcome parameters after TAE following detection in angiography. Results: A total 45 patients 37 (male, mean age, 65.9±14.9 years) were analyzed and classifi ed as a detection group (n=25, 55.5%) and non-detection group (n=20, 44.6%). Peptic ulcers were the most common cause of refractory NVUGIB. Larger transfusion amount (5.7±3.9 unit vs. 3.5±2.8 unit; P=0.03), prolonged aPTT level (34.2±17.3 sec vs. 21.8±13.8 sec; P=0.01) and short time interval between last endoscopy and angiography (17.5±25.9 hours vs. 34.3±59.5 hours; P=0.04) were found to be signifi cant factors for predicting angiographic detection. TAE was performed in all patients detected in angiography. Rebleeding (44%) was significantly associated with higher Rockall score (8.3±1.5 vs. 6.6±2.4; P=0.046) and mortality (12%) was signifi cantly associated with higher Rockall score (9.3±0.6 vs. 7.1±2.2; P=0.002) and higher level of BUN (55.3±47.4 vs. 27.6±17.4; P=0.01). Conclusions: Clinical characteristics associated with angiographic detection in patients with NVUGIB refractory to endoscopic therapy were severe bleeding, bleeding tendency and early angiographic intervention. The Rockall score is useful parameter for predicting rebleeding and mortality after TAE.

1999년 10월에서 11월 사이에 남해안 일대의 홍민어 종묘 생산장에서 20~30열령의 치어가 척추만곡 및 이상유영을 하며 대량 폐사하였다. 병어는 특이 외부 증상이 없었고, 높은 누적폐사량이 바이러스 질병으로 의심되어, 조직학적 및 분자생물학적인 검사를 행하여 폐사원인을 확인하였다. 폐사개체의 조직을 H-E 염색하여 관찰한 결과 뇌와 안구의 신경세포에서 공포와 괴사가 관찰되었고, 전자현미경 관찰에서는 안구와 뇌에서 바이러스 입자가 관찰되었다. RT-PCR 결과에서는 ≒426 bp의 DNA 단편을 확인할 수 있었다. 이러한 결과로 홍민어에서 발생한 대량폐사는 바이러스성 신경괴사증(VNN)으로 진단되었다. Mass mortalities occurred among red drum lavae, 20 to 30 days old, culturing at hatcheries on southern costal area. No specific external signs were observed except abnormal swimming and spinal deformity. It was, however, suspected as a viral etiology due to high mass mortalities so that histopathological and molecular biological study was performed to evaluate the agent. Both vacuoles and necrosis were observed on nerve cells of brain and eye by H-E staining, and viral particles were observed on electronmicroscopic examination. On the other hand, DNA fragment, approximately 426 bps, was amplified with RT-PCR. The above results were able to diagnosis the etiological agent of mass moralities in red drum larvae as VNN(viral nervous necrosis)virus.

This study examined the influences of cooperative construction of portfolio about some concepts in life science in the elementary school. These included four concepts of classification of living organism, comparison, ecosystem, and adaptation to environment. Cooperative activities in the construction of portfolio facilitated the acquisition of correct concepts. Especially, highly significant difference in the area of classification of living things appeared between the traditional and cooperative portfolio groups. When we compared the four concepts, the scores of cooperative group about correct concepts were higher than those of individualistic group. It was revealed that the individualistic construction limited the interaction among children, and children and teacher, while the activities of cooperative construction portfolio activated reflective thinking of children. These results suggest the importance of active and various interaction among children-children and children-teacher. There were no significant differences between the individualistic and traditional groups. As the interaction among children-children and children-teacher activated, it became general trends that children corrected, modified, or complemented their portfolios and became more enthusiastic in such activities. Whole results implied that cooperative and interactive activities have positive influences in the acquisition of correct science concepts.

A group of Protophyta occurring at times in enormous numbers in the sea are the flagellates and the diatoms. A few species are toxic and may multiply rapidly into such dense populations as to cause the deaths of fish and organisms, and then are popularly known as "red-tide", these dense populations occasionally occurring, for example, off the coast of Chinhae Bay, Masan Bay, Kosung Bay and Onsans Bay of Korean southern seashore. These "red-tide" which was caused by the population explotion of phytoplankton are the important problems of seashore culture in Korean seashore areas. These population increases in the phytoplankton tend to occur when high tempreatures(>16℃) coincide with heavy rainfall, which is thought to cause run-off of industrial pollutions and everylife waste substances into the bays from urban district heavily enriched with nitrates. Red-tides have therefore become a major issue for the seashore culture. This study has investgated the organisms and environment factors of red-tide, physico-chemical parameters and eutrophication. These must be taken as an environmental problem of water pollutions.

Spectinomycin (Spc) is an aminoglycoside antibiotic which shows remarkable broad-spectrum. From a chromosomal cosmid library of Streptomyces spectabills, a Spc producer, a clone (pSPM8) was isolated by homology to the dTDP-glucose 4,6-dehydratase and aminotransferase genes which obtained from S. spectabilis genome using a polymerase chain reaction. From this clone, a 5.8-kb DNA region was sequenced and found to encode four open reading frames and one Incomplete reading frame. The putative orfl protein reveals 29% amino acid sequence homology of putative myo-inosltol-2-dehydrogenase from Vibrio anguillarnm. The orf2 is about 46% homologous to putative myo-inositol-1-monophosphotase of Mycobacterium leprae. The orf3 showed strong homology (67.4%) to putative export protein (spcT) from S. flavopersicus. The amino acid sequence deduced from 0114 showed a high similarity (70.8%) to a spectinomycin resistance gene (spcN) from S. flavoperslcus. Expression of orf4 in E. coti BL21 showed the spectinomycin resistance.

This study is to analyze comparatively experimental materials of living things appeared in new text books and old ones according to curriculum units. This survey is how much some teachers college students and element school teachers perceive 16 species of living thing materials and that according to their teaching career. The perceptions of experimental materials of elementary school teachers are higher than those of college students. The perceptions of both college students and elementary school teachers are low in the new text-books including unfamiliar experimental materials. It is necessary to make many experiments of new materials through the science curriculum of the teachers college.

In its seventh revision to start in 2001, mathematics will have a new emphasis in the middle school curriculum. Mathematics subject is now composed of practical things in the use of mathematics. Also, the future of new generation, which has been known as the information age, places much focus on problem-solving in order to collect, analyze, synthesize, and judge various kinds informations. This demand of problem-solving ability is not only related with mathematical education but, along the entire educational process, its related to actual life. With this change of social structure, the importance of school education is increasing rapidly. Therefore, in order to grow abilities and create new knowledge, adapted this new method of self-oriented learning in groups to middle school 2nd graders for one year, the results were as follow : 1. Students developed their ability of the use of mathematical terms and signs correctly. 2. Students' mathematical knowledge and problem-solving ability improved as they had increased interest in mathematics. 3. Students' peership was enhanced through their communication and cooperative activities in groups during the class. 4. Students themselves were more willing to volunteer and participate during the class.

Conditions for processing dried condiments with bloody clam were investigated. The enzymatic hydrolysis for 1 hour was more profitable than hydrothermal extraction to develop flavoring matters from bloody clam. As a result of omission tests, nucleotides were predominated in the taste compounds of bloody clam hydrolysates rather than free amino acids, and the contribution of nucleotides and free amino acids to the taste of bloody clam hydrolysates was remarkable. The major flavoring components of bloody clam hydrolysates were free amino acids and oligopeptides below 500 dalton. When bloody clam hydrolysates were separated with membrane(molecular weight cutoff 500 dalton) for recovering flavor, recovering yields of amino type nitrogen were 92.4%. Proximate compositions of dried condiments prepared with protease hydrolyzed bloody clam were moisture content 3.6%, total nitrogen were 71.2% amino nitrogen were 47.8%. And drying yield, solubility and absorption rates at Aw 0.88 were 21.4%. 86.3% and 6.6%, respectively.

Objectives : Repetitive transcranial magnetic stimulation (rTMS) is a novel, noninvasive method of brain stimulation. Since conventional rTMS does not cause seizure, marked advantage over electroconvulsive therapy (ECT), rTMS can be used easily and widely. Once the effects of rTMS on cognitive function are elucidated, its application will be further extended. However, the effects of rTMS on cognitive function have not been well examined. This study aimed to evaluate the effect of low frequencyr TMS on visual short term memory. Methods : Forty normal healthy volunteers were randomly assigned to rTMS (n=20) or sham (n=20) groups. The rTMS group were again randomly divided into left prefrontal (n=10) and right prefrontal (n=10) groups. For each group rTMS was given at 1 Hz for 20 minutes with 100% of motor threshold. As a cognitive task, Corsi Block Tapping Test (CORSI) in the computerized Vienna Test System, which can assess visual short term memory, was performed before, during, and after the rTMS. Results : No significant difference was found in the visual short term memories between the rTMS and the sham groups before, during, or after 1 Hz rTMS, nor between the left and right prefrontal rTMS groups. Conclusion : This study demonstrates that rTMS, contrary to ECT, has no adverse visual short term memory effect when used as the standard treatment paradigm. Therefore, rTMS could be a new and safe treatment method in various neuropsychiathc fields without any interference of cognitive function.
