Effects of Alkali and Alkaline-Earth Oxides on Thermal, Dielectrical, and Optical Properties of Zinc Borate Glasses for Transparent Dielectric

서병화,김형순,서동학 대한금속·재료학회 2009 METALS AND MATERIALS International Vol.15 No.6

The development of a transparent dielectric layer with a low dielectric constant is essential for improving the luminous efficacy of plasma display panels (PDPs). In this study, a ZnO-B2O3-SiO2-Al2O3 glass containing alkaline-earth oxides and an alkali oxide was fabricated as a candidate Pb- and Bi-free transparent dielectric layer with a low dielectric constant. The thermal, electrical, and optical properties of these glasses were characterized. The changes in the properties in this glass system were investigated according to the alkalineearth oxides (RO)/alkali oxide (R2O) ratio. The glass transition temperature (Tg), the coefficient of thermal expansion (CTE), and the dielectric constant of the glasses varied from 480 °C to 540 °C, 7.9 to 10.6 × 10−6 /K, and 7.4-8.2, respectively. As the RO/R2O ratio was increased, the Tg value increased, the CTE and transmittance decreased, and the dielectric constant increased slightly. The Tg or CTE can be calculated from other known values in these system glasses without requiring numerous experiments. The Tg and CTE are inversely proportional to each other and a constant was obtained by multiplying the two values.

The clinical study on the motility recovery rate of spermatozoa following freeze preservationtwas estab1ished with 45 samplea collected from 15 healthy men. The semen specimens were obtained by ejaculation and allowed to liquify in air at room temperature and routine analysis including concentration, motility, morphology, and pH was performed. No ejaculates were uses for evaluation in this study if initial concentration was less than 60 million/ml, motility was less than 60%. or morphologic examination showed greater than 20% abnormal forms. The ejaculates were then mixed with K-S medium in 1:1 ratio at room temperature and the mixture was then drawn into 45 small glans tules. which were cooled at -79C in ultra-low temperature freezer(dry ice method). The frozen semen specimens were thawed in the 20 to 30C water for 10 to 20 minutes and the motility recovery rate of spermatozoa was obaerved from 1 day to 8 weeks following freeze preservation of semen. The results were as follows: 1) The mean motility recovery rates at 24 hours 48 hours after freezing were 71.8% and 64.8 % , respectively. 2) The range of mean motility recovery rates on 3 days to I week after. freeze preservation was 46.0% to 31.4%. 3) The mean motility recovery raters at 4 weeks and 8 weeks following freeze preservation were 24.6% and 24.3%, respectively.

This study is a clinico-statistical analysis and survey of 260 cases who were admitted and treated for ectopic pregnancy at Soon Chun Hyang hospital from June 1, 1974 to May 31, 1980. The results of this study were as fo11ows: 1. The incidence of ectopic pregnancy was 1 : 34 or 3.0% of deliveries and tends to increase the cases every year. 2. The moat frequent age group was in 25∼39 years of age (81.5%) and the mean age was 31.5 years. 3. Nulligravida was 13.8%, nullipara 29.2% and multipara 70.8% and the cases who have experienced artificial abortion over one time was 65.4% and the last pregnacy ended in normal delivery in 21.2% and artificial abortion in 48.8% of total. 4. The mean duration of sterility was 3 years and 4 months and 7.3% was 9 years or more of sterility. 5. A history of previous artificial abortion was 65.4% and previous laparotomy 19.2%, among them, repeat ectopic pregnancy was 8.1% and appendectomy in 5.4%, and laparoscopic sterilization was 3.8%. 4.6% was pelvic inflammatory disease, vaginitis in 3.5%, pelvic tuberculosis in 1.5%, lUD in 1.5% and cervicitis in 1.2%. The duration between the first and second ectopic pregnancies was distributed in 3 months to 12 years and ifs mean was 4 years and 6 months.

부각자궁 임신의 2예

서병화,정하영 順天鄕病院 1977 順天鄕醫報 Vol.2 No.1

Cornual pregnancy is very rare ans its diagnosis is very difficult due to the distensibility of the uterus at the conus. However, tender cystic enlargement at one horn of the uterus is suggestive of this type of ectopic gestation. This report included two cases of cornual pregnancy which were treated at Soon chun Hyang Gen. Hospital. We present two cases with review of the literature.
