TMCS(Trimethylchlorosilane)로 표면개질한 습윤겔을 에탄올에 재분산시켜 코팅용 재분산 실리카 졸을 제조하였고 제조된 졸을 실리콘 기판에 스핀 코팅한 후 상압 하에서 건조(8$0^{\circ}C$) 및 열처리(>25$0^{\circ}C$)하여 열처리온도에 따른 박막의 물성 변화를 관찰하였다. 습윤겔의 재분산시 안정한 재분산 실리카 졸의 제조를 위한 최적 재분산 조건을 습윤겔:에탄올=1g110$m\ell$로 하였고, 이렇게 제조된 재분산 실리카 졸의 농도와 점도는 각각 0.11 M, 2.0-2.2cP였으며 평균 졸 입자크기는 약 30nm정도였다. 1500rpm, 10회 스핀 코팅한 후 8$0^{\circ}C$에서 2시간 건조, 45$0^{\circ}C$에서 2시간 열처리에 의하여 굴절율이 약 1.14, 두께가 400nm정도인 균열이 없는 박막을 얻을 수 있었다.

The objective of this study was to evaluate the effect of treating dairy cattle with exogenous human chorionic gonadotrophin (hCG), five (5) days post artificial insemination (AI) on serum progesterone (P4) concentration and pregnancy rate. In this experiment, five days after AI, cows were assigned randomly to two groups namely: a) treated group (67) which were administrered with 1500 IU hCG (Chorulon) and b) control group (61), which received no treatment. On day 5, 10, 15 and 20 after the artificial insemination, blood samples from a total of 8 cows (4 from each group) were collected and were analyzed for serum P4 concentration. Cows were detected for estrus according to standing heat by visual observation. Cows that were detected still in estrus after days 18-24 were re-inseminated and recorded as not pregnant (open). Pregnancy diagnosis was conducted by ultrasonographic examination and transrectal palpation of the uterus on approximately 60 days in cows that observed to be not in estrus. The conception rate in hCG treated and control groups were 52.5 and 36.1%, respectively. The results proved that there were no significant differences in conception rate between two groups (p=0.0568). However, pregnancy rates were reduced by hCG treatment. Average serum P4 concentrations did not differ between Hcg-treated and control groups on day 5 (0.377 versus 0.375 ng/ml). On day 20 serum P4 concentrations were greater in the treated group compared with the control group (3.085 versus 2.010 ng/ml). The treatment with hCG seemed to increase P4 level compared with the control. In conclusion, the results of this study showed that 1500 IU of hCG administered on 5 day post AI increased conception rate in dairy cows. This was supported by the results on serum P4 concentration which was greater in hCG treated group.

이 연구는 연령대를 성인, 전기 노인, 후기 노인으로 구분 후 신체활동과 인지된 운동장애요인과의 관련성을 보고자 하였다. 연구 대상자는 두 군데 면 지역에 거주하고 있는 주민들 1500명을 대상으로 실시하였으며 걷기실천율의 정의는 주 5회 이상, 한번 할 때 10분 이상, 하루에 30분 이상 하는 것으로 하였고, 인지된 장애요인은 시간부족, 사회적 지지 부족, 기력 부족, 의지력 부족, 부상에 대한 공포 등 5개의 영역으로 조사하였다. 연령대를 세 개 군(~64세 이하, 65-74세, 75세 이상)으로 구분했을 때 의지력 부족이 모든 연령대에서 유의하였고, 64세 이하의 경우는 시간부족이 관련이 있었으며, 65세 이상은 부상에 대한 공포가 관련 있었다. 결론적으로 의지력 부족과 시간부족에 대한 해결을 위해서 마을 내에서 일정한 시간대에 함께 걷기운동을 실시하여 이를 해결하도록 하고, 노인들에게는 낙상예방을 위하여 걷기운동과 같은 유산소운동을 권장할 때 근력운동을 병행해 실시하여 부상에 대한 공포를 줄여야 할 것이다.

This experiment was performed to study of Gagambipachungpe-Eum extract solution's effects on acne. Anti-inflammatory edema, anti-histamine, vascular permeability, acne by induced oleic acid, ileum contraction of mice and guinea-pig was measured by oral administration, topical application or both of the sample to the acne of the experimental animals. Dose of samples were taken by 500 and 1,500mg/dl at the experiments. The results were as follows. 1. Gagambipachungpe-Eum on rat hind paw edema induced by $0.5\%$ Carrageenin have statistically significant effects on anti-inflammatory edema at 2, 3(p<0.05) and 4 hours(p<0.01) of the high density 1500mg/kg - oral administration group as compared with sample group. 2. Gagambipachungpe-Eum on rat hind paw edema induced by $1.0\%$ Dextran have statistically significant effects on anti-inflammatory edema at 2 and 4 hours of the high density 1,500mg/kg oral administration group as compared with sample group(p<0.05). 3. Gagambipachungpe-Eum on mouse hind paw edema induced by $1.2\%$% Histamine have statistically significant effects on anti-inflammatory edema at 30, 60 and 90 minutes of the high density 1500mg/kg - oral administration group as compared with sample group(p<0.05). 4. Only high density 1,500mg/kg - oral administration group of Gagambipachungpe-Eum as compared with sample group have significant effects on increased vascular permeability induced by histamine, picryl chloride induced contact dermatitis(p<0.01) and writhing syndrome induced by $0.7\%$ acetic acid(p<0.05) in mice. 5. All of the sample groups, Sample-Ⅰ(orally administered), Sample-Ⅱ(topically administered 500mg/kg), Sample-Ⅲ(topically administered 1,500mg/kg), Sample-Ⅳ(administered simultaneous orally and topically) on acne induced by o1eic acid in rabbit ears has the significant recovery on induced acne after 14 days 6. Gagambipachungpe-Eum have the effects on the motility of the isolated mice ileum, on the contraction induced by acetylcholine chloride and barium chloride in the isolated mice ileum and on the contraction induced by acetylcholine chloride, barium chloride and histamine in the isolated Guinea-pig ileum. According to the about results, it is expected Gagambipachungpe-Eum could be applicable to the treatment of acne.

A bacterial strain which formed a distinct colony on agar plate containing phenol as a vapor phase and grew well in a liquid minimal medium was isolated and identified as Acinetobac- ter sp. GEM2. The optimal temperature and initial pH for the growth of Acinetobacter sp. GEM2 were 30$\circ$C and 7.0, respectively. Cell growth was inhibited by phenol at the concentration over 1500 ppm. Cell growth dramatically increased from 10 hours after cultivation and almost showed a stationary phase within 24 hours at which 95% of phenol was concomitantly degraded. Acinetobac- ter sp. GEM2 was capable of growing on aromatic compounds, such as benzoic acid, phenol, m- cresol, o-cresol, P-cresol, catechol, gentisic acid, and toluene, but did not grow on benzene, salicylic acid, p-toluic acid, and p-xylene. By the analysis of catechol dioxygenase, it seemed that catechol was degraded through both meta- and ortho-cleavage pathway. The growth-limiting log P value of Acinetobacter sp. GEM2 on organic solvents was 2.0.

This experiment was designed to analyze the factors, which are very common in practical sewing, affecting on sewing shrinkage by using orthogonal array ($L_{27}$) table. The results were analyzed by using the computer program, PDP 11/10. The results showed that sewing shrinkage was increased up to 3 times of laundrying but no further changes could be found. Sewing shrinkage was affected much by the number of stitching and yarn tension and the rate increased with proportion to the number of stitching in unit length and yarn tension. When cotton yarn was used in P/C fabrics, the shrinkage was much smaller, but this results did not agree with other articles reported. Sewing by using $\sharp$11 needle and 1000$\~$1500r.p.m. seemed to lower the shrinkage rate.

In this study, poly(N-methylol methacrylamide) (NMMAAm) and poly(N-methylol methacrylamide/vinyl sulphonic acid) (NMMAAm-VSA) hydrogels were synthesized by $^{60}Co-{\gamma}$ ray irradiation at an ambient temperature. The graphs belonging to the gelation percent- percent-dose and swelling curves were drawn by using data which were obtained from water and different pH solutions. Characterization of hydrogels was performed by FTIR and DSC-TGA analysis. Heavy metal ion ($Ni^{2+}$, $Co^{2+}$) removal capacities of hydrogels were investigated in aqueous solutions, which had different concentrations (100-1500 mg/L). In metal ion removal studies, pH value of aqueous medium was kept constant at 5.0. Maximum metal ion removal values were obtained for NMMAAm-VSA (1:3 mole ratio) hydrogels. Metal ion removal capacities of NMMAAm-VSA (1:3 mole ratio) hydrogels were found as 82 mg/g and 98 mg/g for $Ni^{2+}$ and $Co^{2+}$ ions, respectively.

Twelve bacterial strains capable of growing on phenol minimal medium were isolated from iron foundry activated sludge by enrichment culture, and amount them, one isolate which was the best in cell growth and phenol degradation was selected and identified as Acinetobacter junii POH. The optimal temperature, initial pH and phenol concentration in the above medium were 3$0^{\circ}C$, 7.5 and 1000 ppm, respectively. Cell growth of Acinetobacter junii POH dramatically increased 20 hrs cultivation-time and reached a almost stationary phsae 40 hrs cultivation-time then phenol was degraded about 98%. Cell growth was inhibited y phenol at concentrations over 1500 ppm. The isolate was resistant to several antibiotics as well as various heavy metal ions. The growth-limiting log P value of Acinetobacter junii POH on organic solvents was 2.9 in the LB medium. Therefore, it is suggested that Acinetobacter junii POH could be effectively used for the biological treatment of wastewater containing the presence of heavy metal ions and organic solvents.
