In an attempt to define the effects of Biphenyldimethyl dicarboxylate(DDB) on the lipid peroxidation, oxygen free radical scavenging enzymes activities and hepatic functions in ethanol-induced hepatotoxic rats, we studies malondialdehyde(MDA) level and the activities of catalse, superoxide dismutase(SOD), glutamic-oxaloacetic transaminase(GOT) and glutamic-pyruvic transaminase(GPT) in liver of the rats at 24, 48 and 72 hr after the injection of ethanol and DDB. Sprague-Dalwey albino rats weighing 250 to 280gm were injected intraperitoneally with ethanol(2.5 gm/kg ) only and ethanol plus DDB(300mg/kg ). The result obtained can be summarized as follows : 1) The group treated with ethanol showed significantly higher MDA level and lower catalase and SOD activities at 24, 48 and 72hr after the injection as compared with that of control group. 2) The group treated with ethanol showed significantly higher GOT and GPT activities at 24, 48 and 72hr after the injection as compared with that of control group. 3) The group treated with ethanol plus DDB showed significantly lower MDA level and higher catalase and SOD activities at 24, 48 and 72 hr after the injection as compared with that of ethanol group. 4) The group treated with ethanol plus DDB showed significantly lower GOT and GPT activities at 24, 48 and 72 hr after the injection as compared with that of ethanol group. These results suggest that the excessive oxygen free radicals resulting from the depression of the activities of catalase and superoxide dismutase is an important determinant in pathogenesis of ethanol-induced hepatotoxicity and DDB has antioxidant effects.

Objective: The conservation of Bali bulls, the Indonesian native breed of cattle, is crucial for cattle breeding in Indonesia. To guarantee the spread of Bali bulls through artificial insemination the quality of the frozen semen must be high. To this end, adding an extender material to semen that increases spermatozoa's survival during cryopreservation is important. Green tea extract (GTE) can be used as cryoprotectant because its high antioxidant activity can help avoid reactive oxygen species formation. Methods: Semen of five Bali bulls from the National Artificial Insemination Center at Singosari, Indonesia was collected routinely twice a week. First, fresh semen inspection was performed to determine the feasibility of using Bali bulls as animal samples. The extender used in this study was Tris-based egg yolk. The samples were divided into four treatments: T0, no GTE added to the extender; T1, 0.05 mg GTE plus 100 mL extender; T2, 0.10 mg GTE plus 100 mL extender; and T3, 0.15 mg GTE plus 100 mL extender. The semen freezing process was conducted according to standard procedures and sperm quality parameters, i.e., sperm motility, viability, abnormalities, and membrane integrity observed pre-freezing and post-thawing. Results: There were significant differences in total motility, progressive motility, viability, and integrity membrane of Bali bull sperm at both pre-freezing and post-thawing after adding GTE into the extender. In contrast, there were no differences in abnormalities among treatments. Conclusion: Adding GTE at a 0.15 mg into 100 mL Tris-based egg yolk extender can improve the quality of cryopreserved Bali bull sperm.

본 연구는 돼지 미성숙난포란의 체외배양시 핵성숙에 미치는 EGF의 효과를 검토하고자 실시하였다. 기초 배양액으로는 TCM-199에 0.2mM pyruvate, 1$\mu\textrm{g}$/ml estradiol-17$\beta$, 25$\mu\textrm{g}$/ml gentamycin을 첨가하였으며, 이 배양액에 EGF, FSH와 FBS을 처리하였다. 실험 1에서는 난포란 성숙에 있어서 FSH와 0, 10, 100 ng EGF/ml의 농도에 따른 효과를 조사하였던 바, 1, 10, 100 ng EGF/ml가 처리된 군의 핵성숙율은 83.0, 86.7, 87.5%로서 무처리군 27.3%와 FSH 처리군 60.3%보다 유의하게 높았다(p<0.001). 실험 2에서는 EGF, FSH와 FBS의 상호작용에 대해서 조사하였다. EGF 단독, EGF에 FSH 첨가, EGF에 FBS 첨가, FSH에 FBS 첨가와 EGF와 FSH에 FBS가 첨가된 군의 핵성숙율은 86.7, 90.2, 87.1, 89.6, 92.6%로서 무처리 군 22.3%, FSH와 FBS가 각각 단독 처리된 군의 52.2, 42.3%보다 유의하게 높았다(p<0.001). 또한, 정상적인 난구세포의 팽창은 FSH에 FBS, FSH에 EGF 혹은 FSH, EGF와 FBS가 첨가된 군에서 나타났으며, EGF가 첨가된 군에서는 대부분의 난구세포가 난포란으로부터 분리되었지만, 일부는 덩어리로 난포란에 부착되어 있었다. 따라서, EGF는 돼지 미성숙난포란에 있어서 핵성숙을 유도할 수 있다고 사료된다.

In order to establish preventive maintenance standards through analysis & reliability prediction of about 60,000pcs of 20kindsof relays and contractors used for Seoul subway trains, several life prediction methodologies were applied. Firstly, Occurrence, Severity, Detection were defined and predicted by applying operation characteristic of EMU to the number of actions of relays & contactors which the manufacturers generally offer as the life cycle data. Secondly, failure distribution and average life of parts were analyzed through interpretation of field data based on a lot of experience which had built up in the field for a long time. Finally, using the 217PLUS standard as a reliability prediction program, comparative analysis of use reliability and inherent reliability was done through reliability prediction at the part level and system level.

Aerodynamic flutter control for long-span cable-supported bridges was investigated based on three basic girder sections, i.e. streamlined box girder section, box girder section with cantilevered slabs and two-isolated-girder section. Totally four kinds of aerodynamic flutter control measures (adding fairings, central-slotting, adding central stabilizers and adjusting the position of inspection rail) were included in this research. Their flutter control effects on different basic girder sections were evaluated by sectional model or aeroelastic model wind tunnel tests. It is found that all basic girder sections can get aerodynamically more stabled with appropriate aerodynamic flutter control measures, while the control effects are influenced by the details of control measures and girder section configurations. The control effects of the combinations of these four kinds of aerodynamic flutter control measures, such as central-slotting plus central-stabilizer, were also investigated through sectional model wind tunnel tests, summarized and compared to the flutter control effect of single measure respectively.
