Background/Aims: Inflammatory diseasas of the pancreas are not uncommon. The advanced age is one of the significant factors in assessing the severity of acute pancreatitis. It has been shown that the biliary tract disease is a more frequent cause of acute pancreatitis in the elderly than in the young. With the increased life span, the elderly are comprising a large proportion of the population. As a result, physicians are more often being faced with acute pancreatitis in the elderly. The purpose af this study was to evaluate clinical features of acute panereatitis in the elderly. Methods: A total of 188 patients with acute pancreatitis were reviewed. We investigated the differences of clinical characteristics between the elderly patients aged over 60 and the young patients aged under 60. Results: The sex distribution showed male preponderance in the young patients (M:F=2.4:1), but was nearly equal in the elderly patients (M:F=1.1:1). The most common cause of acute pancreatitis in the elderly was biliary tract disease (52.5%), while alcohol abuse was the most common cause in the young patients (38.8%), Local complications of acute pancreatitis, such as psuedocyst, necrosis, abscesses were not differently shown between the elderly (16.9%) and the young (20.2%) patients. Systemic complications including acute puhnonary failure occurred more frequently in the elderly patients than the young patients. The mortality rate of the elderly patients (5.1%) was not significantly different from that of the young patients (3.1%). Conclusions: To detect correctable underlying bihary tract diseases the elderly patients with acute pancreatitis should be completely investigated using endoscopic retrograde cholangiopancreatography (ERCP). In addition, the patient should be closely monitored for the development of the systemic complications during the disease process.

Clinical manifestations and results of photocoagulation therapy were reviewed in the thirty patients with branch retinal vein occlusion. The average age was 54.3 years old. Most commonly involved vein was superior temporal branch retinal vein. Systemic hypertension and diabetes mellitus were the commonly associated systemic diseases. Macular edema and neovascularization complicating retinal branch vein occlusion produced a profound visual disability. Nine patients with persistent macular edema, neovascularization and extensive retinal capillary nonperfusion area were treated with argon laser photocoagulation. Of those, visual acuity and fundus picture improved in five patients, aggravated in one patient and were stationary in three patients.

윤영복,하성규 漢陽大學校 工學技術硏究所 1998 工學技術論文集 Vol.7 No.1

3차원 적층 복합재 구조물의 해석을 위한 3차원 다적층 복합재 육면체 요소가 적층정보 자동 입력 모듈과 함께 제안되었다. 개발된 요소는 요소내에 다양한 물성치 정보를 포함하며 가장자리에 적층 절단면이 존재하는 요소의 해석이 가능한 ply-drop-off요소이다. 요소의 정확도가 엄밀해와의 변위 및 면내응력의 비교를 통해 검증되었다 개발원 요소는 전형적인 유한요소법에 손쉬운 정식화 및 적용이 가능하며 개발된 요소와 제안된 적층정보 인식 모듈은 엄밀해와 비교, 검증되었다. 본 요소를 사용함으로써 정확도의 변화없이 해석시간과 저장용량 및 요소를 현저히 줄일 수 있다. A three-dimensional multilayered brick element with automatic input module of layup information in the element is developed to analyze the behavior of complicated three dimensional laminated composite structures. The developed element can contain the varying material properties within the element and allow the ply-drop-off along the element edges. The accuracy of the displacement using the element is well verified with the analytical solution. The computer time and memory space can be significantly saved using the ply-drop-off element. This method is easy to formulate and apply for the conventional finite element method. Exact solution is compared with the results using the developed element and proposed method. While the number of element is quite reduced, the results still have a satisfactory accuracy.

This study was carried out to investigate the correlation of ovarian follicular characteristics in vaginal ultrasonography with serum estradiol level in human in vitro fertilization and embryo transfer(IVF & ET) program hyperstimulated by using of pure follicular stimulating hormone (FSH) and human menopausal gonadotropin(hMG). The results were as follows: 1) Total amount of FSH and hMG administered in the process of hyperstimulation were 300IU and 772±157.5IU respectively. And the number of follicles which were more than 12mm in diameter in vaginal ultrasonography on the day before the aspiration were 6.0±3.7. 2) The greatest number of follicles which were more than 10mm in diameter were 7.4±3.8 on the day after administration of hCG. The serum estradiol level was increased according to the increase in number of follicles of more than 10mm diameter(r=0.9632) 3) The largest diameter of dominant follicles were 19.9±2.3mm which happened on the day after administration of hCG. The serum estradiol level was increased according to the increase in diameter of dominant follicle(r= 0.9791). 4) The total number of oocytes aspirated was 180 from 35 hyperstimulated cycle, which was equivalent to 5.1±3.9per cycle. Of these, the number of mature oocytes was 4.1±3.8per cycle. The ferilization rate of mature oocytes and cleavage rate of Proombryos were 75.6% and 53.7% respectively. In conclusion, ovarian follicular characteristics in vaginal ultrasonography had strong postive correlation with serum estradiol level in controlled ovarian hyperstimulation process. So. therefore, vaginal ultrasonography would be an important parameter to be able to replace serum estradiol test in vitro fertilization and embryo transfer program.

Ethylene Glycol Monoethyl Ether가 흰쥐 정소의 형태와 복합당질의 Lectin 결합 양상에 미치는 영향

염영옥,정길남,조운복 부산대학교 과학교육연구소 2007 교사교육연구 Vol.46 No.2

Ethylene glycol monoethyl ether(EGEE)를 투여한 휜쥐 정소의 조직학적 구조와 glycoconjugates에 대한 lectin 결합양상에 미치는 영향을 규명할 목적으로 250~300g의 Sprague-Dawley 계 수컷 흰쥐를 사용하여 대조군과 EGEE 투여군으로 나누고, EGEE 투여군은 다시 EGEE 1주, 2주, 3주 및 4주 투여군으로 나누었다. 조직학적인 변화는 H-E 및 PAS 염색으로 관찰하였고, glycoconjugates의 당잔기 변화는 avidin-biotin-peroxidase complex 법으로 biotinylated lectin (DBA, SBA, PNA, BSL-1, sWGA, RCA-1, UEA-1, Con A, LCA)를 사용하였다. EGEE 2, 3, 및 4주 투여군에서는 대조군에 비해 정소의 크기, 정세관의 직경, 정모세포와 정자세포의 수가 감소되었다. 정조세포와 버팀세포의 위축 또는 파괴가 모든 EGEE 투여군에서 관찰되었으며 이러한 변화는 투여기간이 길어질수록 심하였다. 정모세포와 정자세포는 EGEE 4주 투여군에서는 관찰되지 않았다. EGEE 투여군에서는 대조군에 비해 정조세포의 PNA, RCA-1 및 sWGA 반응성이 감소하였으며 특히 LCA, Con A의 반응은 뚜렷하게 감소하였다. 대조군에 비해 EGEE 투여군의 정모세포는 SBA는 조금 증가하고, PNA 반응은 크게 증가하였으나 LCA와 Con A의 반응은 현저히 감소하였다. 정자세포는 EGEE 투여군에서 대조군에 비해 PNA는 크게 증가하였다. 버팀세포의 PNA, UEA-1과 sWGA 반응은 EGEE 투여군에서 감소되어 소실되는 경향을 나타내었다. 사이질세포에서는 UEA-1 반응성은 소실되었으며 BSL-1 및 Con A 반응성은 EGEE 1주 투여군에서 약간 증가하였으나 Con A는 4주 투여군에서 현저히 증가하였다. 결론적으로 EGEE는 흰쥐 정소 정세관의 정세포 발생과 정자 형성 및 정소의 glycoconjugates 대사에도 심한 영향을 미치는 것 같다. This study was performed to investigate the effects of ethylene glycol monoethyl ether(EGEE) on the histological structure and glycoconjugates of seminiferous tubules of the rat. Sprague- Dawley male rats weighing about 250~300g were divided into a control and EGEE-administrated groups. EGEE-administrated groups were subdivided into 1, 2, 3 and 4 weeks of administrated group. To find the histological changes, H-E and PAS stainings were used and to investigate the changes of sugar residues of glycoconjugates, biotinylated lectins (DBA, SBA, PNA, BSL-1, sWGA, UEA-1, LCA, and Con A) were applied with avidin-biotin-peroxidase complex method. Decrease in size of testis, diameter of seminiferous tuble, number of spermatocyte and spermatid were observed in 2, 3, and 4 weeks-administrated group. The shrinkage or demolition of spermatogonia and Sertoli's cells was observed frequently in all EGEE-administrated groups. These changes became more severe as the administration continued. In 4 weeks administrated group, no spermatocyte and spermatid were found. The binding of PNA, RCA-1 and sWGA of spermatogonia tended to decrease, and the reactivity of LCA and Con A decreased significantly in the EGEE-administrated group. In the spermatocytes, SBA affinity increased slightly, PNA reaction increased abundantly, but the affinity of LCA and Con A decreased remarkably in all administrated groups compared with the control group. In the spermatid, the binding of PNA increased notably in the administrated group compared with the control group. In the Sertoli's cells, PNA, UEA-1 and sWGA affinity showed the pattern of decreasing and disappearance in the administrated groups compared with control group. In the Leydig's cells, UEA-1 affinity disappeared, BSL-1 and Con A binding tended to increase slightly in 1 week-administrated group, whereas Con A affinity increased remarkably in 4 weeks-administrated group. In conclusion, it was assumed that EGEE induced seriously toxicity which affected spermatogenesis and spermiogenesis of seminiferous tubules, and metabolism of glycoconjugates of the testis.

The microleakage of direct-access Class 2 restorations was evaluated. Cavities were prepared at mesial and distal proximal enamel surfaces of 20 extracted human molars through buccal window. Prepared cavities were filled with Ketac-Fil, Ketac-Silver, and Fuji Ⅱ LC, following manufacturer's instructions. 4 specimens of each restorations were made through sectioning 1/4 of bucco-lingual length mesio-distally after thermocycling between 5℃ and 60℃ and imerging 0.5% basic-fuchsin dye solution. Leakage at both occlusal and gingival margin of each specimen was scored 0 to 3 with stereomicroscope. The results were as follows: 1. At occlusal margin, leakage in Ketac-Fil group was more than Ketac-Silver and Fuji Ⅱ LC group(ANOVA p<0.05) and there was no significant difference between Ketac-Silver and Fuji Ⅱ LC goup(p>0.05), and at gingival margin, there was no significant difference amang materials(p>0.05). 2. Occlusal margin leaked more than gingival margin in Ketac-Silver and Fuji Ⅱ LC group(t-test p<0.05). 3. Leakage was different according to bucco-lingual location in Ketac-Fil and Fuji Ⅱ LC group, and lingaul specimen exhibited more leakage(ANOVA p<0.05).

The objective of this study is to compare the results of the twenty-one eyes of central serous choroidopathy which were treated with argon laser photocoagulation with the fourteen eyes which were not treated because the leakage site was located within 230um. of the capillary-free zone. The results are summarized as follows: 1. Average duration of serous detachment was 3. 4 months in the nontreated group and 2.3 months in the argon laser photocoagulated group. Complete recovery as shown by resolution of serous detachment occured at a mean time of 1 month from photocoagulation. 2. Average initial visual acuity was 0. 6 in both the treated and nontreated group, and average final visual acuity was 0. 9 in the treated group and 1. 0 in the nontreated group. 3. There were no complications from photocoagulation in any of the eyes.

이영심,조운복 부산대학교 사범대학 과학교육연구소 2004 科學敎育硏究報 Vol.31 No.-

The purpose of this study is to provide the basic data of educational activities on the school scene, by finding the extent of agreement between the educational purposes of high school science textbooks by the 7th curriculum and those of science curriculum, and by dividing the contents of STS into the subject and activity area. In the study, the contents of STS were analyzed by e eight elements in STS course as Yager and student activities of SATIS. The results are as follows ; 1. The STS material are included average 20.8%, the highest 26.2%(textbook G) and the lowest 15.6% (textbook E) and the STS material are included 67.9% in the chapter of Biological concentration, 19.9% in Reproduction, 13.1% in metabolism, 9.9% in Stimulation and Reaction. 2. The contents of STS were analyzed by the STS standards presented by Yager(1984, 1989). The majority of the STS contents integrated 'application of science' and 'practice with decision - making strategies', 'social problem', relation of local communities', but didn't include evaluation concerned getting and using information. 3. The STS program suggested by SATE in the textbooks are mostly 'data analysis', 'practical work' and survey. But there is no case study. In STS material, 'application of science' were heavily concentrated while the activity category geared towards 'data analysis' and 'practical work', which leads to the conclusion that less diversity of STS contents and activity were included. 본 연구의 목적은 제7차 교육과정에 의한 고등학교 과학과 STS 내용의 교과서 분포상황을 분석하여 각 교과서가 교육과정의 교육목표에 얼마나 부합되었는지를 알아보고, 학교 현장에서의 교육활동에 필요한 기초 자료를 제공하는데 있다. 본 연구에서 STS 내용은 Yager(1984)가 제시한 8가지 요소와 SATIS program에 나타난 활동유형을 기준으로 분석하였다. 결과는 다음과 같다. 1. 과학 교과서의 '생물'영역에서 STS 교육 내용의 포함률은 평균 20.9%로 최고 26.2%(교과서 G)에서 최저 15.6%(교과서 E)의 지면을 할애하고 있다. 그리고 중단원별 포함률은 생물농축 단원이 67.6%로 가장 높고, 생식 단원 19.9%, 물질대사 단원 13.1%, 자극과 반응 단원이 9.9%로 나타났다. 2. 과학 교과서 '생물'영역에 포함된 STS 내용 포함 횟수는 평균 24.7회로 최고 31회에서 최저 15회로 나타났는데, 과학의 응용성에 관한 것이 가장 많았고, 실제 문제의 협동작업, 사회적 문제, 지역사회와의 관련성, 과학과 관련된 직업 선택, 과학의 다면성, 의사결정 함양 능력 순으로 나타나며, 정보의 선택 및 이용에 관한 내용은 거의 다루어지지 않았다. 3. 과학 교과서 '생물'영역의 STS 내용을 SATIS 활동 영역에 따라 분석한 결과 평균 38회로, 최고 46회에서 최저 30회인데 자료 분석이 가장 많았고, 실제 활동(실험), 조사 활동, 구조화된 토론, 역할놀이 및 모의실험, 문제 해결 및 의사 결정과 연구 설계 순으로 나타났고, 사례 연구는 한번도 제시되지 않았다.

The purpose of this study was to investigate the antioxidative effect and quality characteristics of cookies made with Lvcii fructus powder(LFP). The cookies were stored at 50 ℃ for 40 days. The LFP additive increased the moisture, ash, crude protein and volume of the cookies. When LFP was added at 5% into the cookies, the spread ratio was higher than for the control, the 10% and the 20% LFP cookies. As more LFP was added, the L-value decreased, and the a--values and b-values increased for thecolor values. For the textural characteristics, springiness and cohesiveness of the control cookies were the highest among the samples, the other side, brittleness and gwemwness were higher in cookies made with LFP than in the control cookies. Overall, the cookies made with 5% LFP were preferred more than the other cookies, as tested forby sensory evaluation. The cookies made with LFP contained mostly palmitic acid (C16:0) followed by oleic acid (C18:1) and stearic acid (CI8:0). The acid value, peroxide value, and thiobarhituric acid value were lower in cookies made with 5% and 10% LFP than in those cookies made with 20% LFP and the control cookies.
