Ormocer has organic-inorganic compound polymers. One of advantages of ormocer is reduced polymerization shrinkage. The purpose of this study was to compare the amount of contraction shrinkage of composite resins and ormocers. Additionally, the time of each material when there is no further change of contraction shrinkage was analysed. Four brands of composite resins (P-60, Surefil, Z-250 and Denfil) and two brands of ormocers (Definite and Admira) were used. 20 seconds, 40 seconds and 60 seconds of curing times were given. Contraction shrinkage of them were measured using a linometer for 80 seconds. The effect of material and curing time to contraction shrinkage at the time of 80 seconds was analysed by two-way ANOVA. The effect of time to contraction shrinkage was analysed by one-way ANOVA, and the time when there was no further change of the contraction shrinkage was analysed. The results are as follows : 1. P-60, Dfinite, Z-250 and Denfil had no further change of contraction shrinkage from the time of 20 seconds, and Surefil and Admira had no further change of contraction shrinkage from the time of 10 seconds. 2. Statistical analysis revealed volumetric shrinkage varied among material (p<0.05). No significant difference of contraction shrinkage among different curing times was found, and there was no effect of interaction between materials and curing times to contraction shrinkage. 3. Dfinite and Admira showed the statistically same contraction shrinkage with those of Z-250 and P-60, which is higher than that of Surefil and lower than that of Denfil (p<0.05).

정용모,서정해,조만현,권오창 東亞大學校生命資源科學大學附設 農業資原硏究所 1996 農業生命資援硏究 Vol.5 No.1

부산근교의 고산 지대에 자생하는 야생 노랑제비꽃(Viola orientalis W. Becker)의 외부 형태적 특성과 줄기 조직으로부터 callus형성에 미치는 식물 생장조절제의 영양에 관한 실험을 실시하였던 바 그 결과를 요약하면 다음과 같다. 잎은 근생엽과 줄기상의 잎으로 구별할 수 있었으며, 엽장, 엽폭, 그리고 엽면적 각각 3.9㎝, 4.7㎝ and 15㎠로 모두 근생엽이 skjawl 줄기상의 잎보다 컸다. 그러나 엽형지수에 있어서는 근생엽이 0.83으로 가장 작았고 줄기상의 가장 작은 잎이 1.30으로 제일 크게 나타났다. 식물 생장조절물질의 단용에서 callus 유도는 Auxin의 NAA5×10??, 5×10??, 5×10??M에서 양호하였다. Auxin과 Cytokinin의 혼용에서 callus유도는 NAA 5×10??M 및 5×10??M에 BA 5×10??, 5×10??, 5×10??M의 전구에서 양호하였다. Callus 성장이 가장 양호한 조합은 NAA 5×10??M + BA 5×10??M 및 NAA 5×10??M + BA 5×10??M이었다. This experiment was conducted to study morphological feature and effect of plant growth regulators on callus induction of wild viola(Viola orientalis W. Becker). The results obtained were summarized as follows: In morphological feature, there was two distinctive leaf-forming types : one was rosette type derived from subterranean stem and the other was leaves formed on stem. Generally rosette type leaves were larger than others and the leaf length, leaf width, and leaf area were 3.9㎝, 4.7㎝ and 15㎠ on average, respectively. In the leaf shape index(the ratio of leaf length/width), the smallest value(0.83) was shown on rosette leaf while the greatest value(1.30) was determined from leaves on stems. Callus induction from the stem segments of wild viola was relatively higher at NAA concentrations of 5x10??M, 5x10??M or 5x10??M than at the same ones of other regulators used. The most effective combined concentrations of Auxin and Cytokinin for the callus formation were 5×10??M of NAA plus 5×10??M of BA or 5×10??M of NAA plus 5×10??M of BA.

Action potential of a frog ventricular cell was studied by conventional 3M KCI glass microelectrodes to investigate the effect of freeze-dried Korean snake venom. Following results were obtained; 1. Time to repolarize 50% of its action potential increased from 756±26mS to 796±17mS. 2. The notch which would be seen after the fast depolarization disappeared and the overshoot potential significantly decreased from 24.4±0.9㎷ to 17.8±2.3㎷. 3. Positive depolarization rate (dV/dt max) decreased from 22.8±0.8V/s to 18.8±0.8V/s. 4. Resting membrane potential was -95±3.0㎷ and showed little change. Above results would be interpreted that the Korean snake venom blocked the fast sodium channel and slow calcium channel simultaneously to reduce the contractility and activation of potassium channel which could result the prolongation of action potential duration.

Database design is the base of the entire process related to the database, and the well-designed database schema has a great effect on the system performance. So, there's a growing need for the automatic schema generation system. In this paper, database design automation system is implemented which translates automatically OMT based database model to relational database table. For developing this system, transformation rules of OMT into RDB schema are suggested which satisfy normalization and integrity constraints. This automation system can be used efficiently in the area of training database system and applying database design in actual business fields.

Ovarian pregnancy is an uncommon form of the ectopic pregnancies. The ovarian vascularity results in maternal hemorrhage early in the first trimester, which disrupts the pregnancy and usually ruptures the ovary with sufficient hemoperitoneum to require emergency operation. This report presents 10 cases of ovarian pregnancy by retrospective review between January 1986 and December 1995 at the Department of Obstetrics and Gynecology, Soonchunhyang University Hospital. There was 19,849 deliveries and 637 ectopic pregnancies during same period. It showed that the incidence of ovarian pregnancy was 3.21 % of all ectopic pregnancies. The clinical features of ovarian pregnancy revealed that abdominal pain was the major symptom, and history of amenorrhea was obscure. Because of life-threatening course, the early diagnosis and treatment of ovarian pregnancy is important. The clinical diagnosis of ovarian pregnancy was more difficult than that of tubal pregnancy.

기업의 효율적인 데이터베이스시스템 구축은 정보화 사회에서 반드시 필요한 사안으로 이를 통해 자료연계, 최신 정보의 입수 등 기존의 회사 생존 전략을 벗어난 세계화와 정보화를 유지할 수 있다. 이를 위하여 중소 업체에서는 한 번에 많은 투자를 해야되는 종합 정보화시스템의 도입보다는 생산 관리, 인사 관리, 회계 관리 등 각각에 대해 프로그램들을 개발하여 사용하고 있으나, 서로 각각 개발된 프로그램들은 그 활용도나 연관성 면에서 유용성이 떨어지게 마련이다. 따라서 이들 시스템간에 서로 자료를 교환하고, 의사결정을 위한 정보를 효과적으로 제시해 주는 종합 정보관리 시스템을 구축하여야 하는데, 이를 위하여 기존에 개발된 영업관리, 생산 관리, 인사 관리, 회계 관리 등의 프로그램들을 통합하는 것이 새로운 시스템을 개발하는 것보다 경제적, 기능적 측면에서 매우 유리하다 할 것이다. 따라서, 본 연구에서는 두양금속 주식회사의 기존에 사용중인 영업관리, 생산 관리, 인사 관리, 회계 관리 시스템의 통합을 목표로 하여, 이미 구축된 시스템을 분석하고 연계하여 효율적인 정보 관리 시스템을 구축하고 있다.

Changes of free amino acids a s taste compounds during sun drying of shrimp Trachypenaeus curvirostris, were analyzed by amino acid autoanalyzer. Glycine, arginine, proline and alanine were dominant amino acids in fresh extracts, having 44.8%( 6109.9㎎%, on dry base), 21.9% (2989.3㎎%), 10.4% (1418.3㎎%)and 5.9% (805.1㎎%) of the total amino acids, respect-ively. Free amino acids were not changed in composition during sun drying of shrimp. Glycine, arginine, proline and alanine were dominant in both fresh extracts and dried products. In dried extracts,.such amino acids as glycine, arginine, proline and alanine were 44.7% (4162.3㎎%, on dry base), 24.1% (2244.61119 %), 11.7% (1090.l㎎%)and 5.3% (495.8㎎%) of the total amino acids, respectively. It is believed that glycicne, arginine, proline and alanine may play an important role as taste compounds in sun dried shrimp.

Pleural effusion in a patient with multiple myeloma due to plasma cell involvement of the pleura has been reported infrequently. We report a case of multiple myeloma with pleural involvement presenting bone pain and dyspnea in a 69-year-o1d woman. On the physical examination, the patient looked chronically ill with bedridden state. There was a palpable mass on the left posterior lower chest, firm but not tender and decreased breathing sound in the left lower lung. Laboratory finding revealed amemia, elevation of ESR, globulin, and calcium. X-ray of the chest showed pleural effusion in the left lower lung, and multiple pathologic fractures in the both ribs. X-ray of the skull, and pelvis revealed multiple punched-out osteolytic fractures in the both ribs. X-ray of the skull, and pelvis revealed multiple punched-out osteolytic lesion, and compression fracture in the lumber spine. Serum and urine electrophoresis revealed a M-spike. Serum and urine immunoelectrophoresis demonstrated an IgA-kappa monoclonal protein. Thoracentesis revealed serosanguinous fluid but not containing atypical plasma cells. Bone marrow examination showed 16.7% of immature plasma cells. With first cycle of melphalan, prednisone chemotherapy, improvement of pain and disappearance of pleural effusion was observed.

Sodium molybate가 납중독 랫드의 말초신경내 myo-inositol 인지질 대사 관련 효소에 미치는 영향

We have previously demonstrated that sodium molybdate(Mo) improved lead-intoxicated status by enhancing the metabolism of myo-inositol-related phospholipids in sciatic nerves isolated from rats. In this study, in order to address the reduction mechanism of Mo for lead toxicity, effects of Mo on cystidine-diglyceride transferase, phosphatidylinositol kinase, and phosphatidyl inositol-4-phosphate kinase, involved in myo-inositol metabolism of nerve, were investigated in vivo and in vitro. Mo significantly increased the activities of cystidinediglyceride transferase and phosphatidylinositol kinase in lead-intoxicated rat, and the pattern of increase was dose-dependent manner. However, Mo did not affect the activity of phosphatidylinositiol-4-phosphate kinase in normal and lead-intoxicated rats. We also found that Mo affected the activities of phopholipid metabolism-related enzymes not by the indirect manner such as activation of another metabolic pathway but by the direct manner. These results suggest that the improvement mechanism of Mo for lead-intoxicated status might be a normalization of the activities of phospholipid metabolism-related enzymes in sciatic nerve.
