Background: Pregnancy affects the course of Graves' Disease (GD), and patients who initially maintain euthyroid function into their middle trimester with minimum doses of antithyroid drugs become exacerbated after delivery. Even patients who are completely cured, requiring no treatment during pregnancy, can relapse after delivery. In this study, we examined the postpartum changes in the thyroid functions of patients with GD, and attempted to determine the factors contributing to these changes. Methods: The study subjects were recruited from pregnant women visiting our outpatient clinic for routine prenatal evaluations. 45 women previously diagnosed with GD, who had been treated and cured with hyperthyroidism, and were no longer taking any thyroid medications, were evaluated for 1 year post delivery. Results: Among 45 patients, 20 (44.4%) developed thyroid disorders following delivery. Postpartum thyroiditis (PPT) developed in 8 patients (17.8%), and GD developed in 12 (26.0%). The onset of the PPT disease 3.1 ± 1.4 months following delivery, which was significantly earlier than the 6.7 ± 2.7 months required for the post delivery onset of GD (p=0.003). The TBII values, measured during the thyrotoxic state in each womaen, were negative in women with PPT and positive in 71.4% of women with GD (p=0.030). The duration of treatment for hyperthyroidism prior or pregnancy, the number of recurrences, and the time interval without treatment, were not associated with the development of postpartum thyroid disorders. Whereas, the mean number of past pregnancies for women who developed PPT was 3.9 ± 2.1, and was significantly higher than the 2.2 ± 1.7 for women developing no thyroid dysfunctions (p=0.044). In 13 women their initial onset of GD occurred within one year postpartum, 7 (53.8%) having had a recurrence, which was significantly higher than in women whose disease onset occurred unrelated to delivery (5 of 32 women: 15.6%). Conclusion: Women with GD developed postpartum thyroid dysfunctions in 44.4% of cases. Women whose initial disease onset occurred within one year postpartum had higher recurrences of GD, and women who developed PPT had a history of higher gravidity compared to the euthyroid women postpartum. Therefore, if women with GD develop postpartum thyroid dysfunctions, the diagnosis should be made, and a treatment modality planned, following careful considerations of the patients' past obstetric history, changes in clinical manifestations and the TBII values

생·찐솔잎에 콩기름과 올리브유를 첨가하여 추출한 솔잎추출유의 저장기간에 따른 산패도를 측정하였고 솔잎추출물을 김에 발라 제조한 맛김에 대한 관능검사 결과는 다음과 같다. 1.저장기간에 따른 중량변화 특정 결과, 콩기름은 14일째 생·찐 솔잎추출유는 21일째 생·찐 올리브유 솔잎추출유는 14일부터 중량이 서서히 증가하여 28일에 중량이 가장 크게 증가하는 것으로 나타났다. 2.TVARS 생성량도 저장기간 14일째 콩기름에 비해 콩기름에 생·찐 솔잎을 첨가할 경우 TBARS의 함량이 유의적으로 낮았고, 28일째 올리브유도 생·찐 솔잎을 첨가할 경우 TBARS의 함량이 유의적으로 낮게 나타났다. 3.시방산 산화의 2차 생성률은 aqueous layer에서 저장기간에 다라 감소하였고 특히 14일째에 다른 추출유에 비해 콩기름이 크게 감소한 것으로 나타났다. 한편 organic layer는 저장기간 14일째 콩기름에서 가장 크게 증가하였고 솔잎을 첨가할 경우 유의적으로 감소한 것으로 나타났다. 올리브유의 경우도 솔잎을 첨가한 올리브 솔잎 추출유에서 2차 생성률이 감소한 것으로 나타났다. 4.제조된 생·찐 솔잎 추출유를 김에 발라 7점 기호척도법을 이용하여 관능검사를 실시한 결과 향, 맛 전반적인 기호도 모두 유의적인 차이가 나타나지 않아 솔잎추출유를 김에다 바를 경우 거부감을 주지 않는 것으로 조사되었다. 이상의 경우 솔잎에 콩기름과 올리브유를 첨가하여 추출한 솔잎추출유는 원유보다 산화에 대해 안정한 것으로 나타났고, 이를 이용한 맛김도 좋은 것으로 평가되어 솔잎추출유의 식품에 이용 가능성이 시사되었다. In order to evaluate the oxidative stability and sensory evaluation for the pine needle extracted oils, we prepared the pine needle extracted oils by the autoclave method with soybean and/or olive oils. The lipid peroxidation was monitored by measuring the formation of 2-thiobarbituric acid reactive substances(TBARS). In addition, the secondary reaction products of lipid oxidation were measured by fluorescence spectroscopy. A weight changing was decreased in oils added pine needle during storage periods. The formation of TBARS was the lowest in olive pine needle oils after 14 days storage, whereas it was the highest in soybean oil. The levels of fluorescent products in extracted oils added pine needle were also decreased in organic layers. According to the sensory evaluation, the scores of fragrance, taste and overall preference in savored laver using an pine needle extracted oils were no significant differences. Overall results suggest that the pine needle extracted oils can be developed to functional oil resources.

This paper describes an effort to develop a microcomputer-based parameter identification system for a brushless D.C.motor driven by three phase trapezoidal current. It is found that Pasek’s equation is valid for the brushless DC motor driven by three phase trapezoidal current. Back EMF equation is derived from back EMF waveform of brushless DC motor driven by three phase trapezoidal current and it is verified that the voltage constant obtained by back EMF equation and the torque constant are equal, in the pure SI metric system. To minimize errors due to the ripple component in the measured armature current, digital averaging filter is employed. The algorithm is implemented on IBM-PC/AT using C language. In the proposed method, the measured current is in excellent agreement with the calculated current. And this close agreement conform the validity of this technique.

실리콘 웨이퍼 태양전지의 효율 향상 방안

김정근,박해웅,장영철 한국기술교육대학교 2006 論文集 Vol.12 No.1

In the process of ingot pulling of the Si single crystal, the pulling velocity of the single crystal silicon should be faster than the dislocation propagation velocity in order to have uniform resistivity in (100) plane. The (100) plane has no dislocation when single crystal seed is contacted and seperated from the melt. Oxygen content of the Si ingot should be controlled by melting Si in Ar gas atmosphere with magnetic field to increase the viscosity of the melt. The efficiency of the Si wafer solar cell can be enhanced by (1) removing the defects in the Si wafer, (2) minimizing the recombination and thermalization of the atoms which lead to energy loss, (3) forming pyramid structure on the cell surface to reduce reflection of the light. The shading of the cell can be minimized via controlling of the finger width of the solar cell. the atoms which lead to energy loss, (3) forming pyramid structure on the cell surface to reduce reflection of the light.

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.

Korean universities have developed rapidly since its liberation from hapanese rule in 1945. Korean higher education system has contributed to the socio-economic development of the country. However, Korean higher educational system has some problems. One of the problems is its unbalanced development of higher educational institutions between the capital city and other cities. Koreans traditionally regarded highly colleges and universities in the capital city. The government including private foundations have invested large resources in building colleges and universities in cities and providences had been neglected. However, colleges and universities play crucial role in the local, regional development of the country. It is important to raise academic quality of the colleges and universities in non-capital cities. The quality of colleges and universities depended primarily on faculty, finance, etc. Therefore, it is an imperative condition to recruit academically excellent students for the development of colleges and universities in non-capital cities. Three research questions have guided the research. 1) How the college entrants' academic performance has changed. 2) What colleges and universities have utilized admission policy to recruit excellent students. The research has found out the following results. 1) The academic performances of college entrants in non-capital city were lowered in the 1980s. 2) Colleges and universities have emphasized the academic excellence, which is primarily related to research and academic activities of the faculty. 3) High school students and teachers in Pusan city give local university lower rate than what it is The findings suggest that local college and university make sustained, ststematic efforts in order to develop its status among the institutions. The efforts should include short-term and long-term policies : 1) Marketing activities about scholarship programs, graduates' career prospects, facilities, and the faculty etc. 2) Hiring excellent faculty members 3) Strengthening graduates' gaining job 4) furnishing required facilities and making attractive campus 5) Upgrading the quality of academic and research activities
