To develop and aceclofenac soft capsule, four preparations with various solubilizers were prepared and their dissolution test was carried out. Among four preparations tested, a preparation with ethanolamine was selected a formula of aceclofenac soft capsule (Clanza S^(™), since it showed the fastest dissolution rate. Bioequivalence of aceclofenac tablet, Airtal^(™)(Dae-Woong Pharmaceutical Co., Ltd.) and aceclofenac soft capsule, Clanza S^(™)(Korea United Pharmaceutical Co., Ltd.) was evaluated according to the guideline of KFDA. Fourteen normal male volunteers (age 20-25 years old) were divided into two groups and a randomized 2×2 cross-over study was employed. After oral administration of one tablet or capsule containing 100 ㎎ of aceclofenac, blood ws taken at predetermined time intervals and the concentration of aceclofenac in plasma wa determined with an HPLC method under UV detector. The pharmacokinetic parameters (C_(max), T_(max) and AUC_(t)) were calculated and ANOVA was utilized for the statistical analysis of parameters using logarithmically transformed AUC_(t), C_(max) and T_(max) between Airtal tablet and Clanza soft capsule were 2.89%, 0.18% and 43.0%, respectively. There were no sequence effects between two formulations in these parameters. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log(0.8) to log(1.250(e.g.log(0.81) - log(1.23) and log(0.89) - log(1.14)) for AUC_(t) and C_(max), respectively. Thus, the criteria of the KDFA guidelines for the equivalence was satisfied, indicating that Clanza S^(™) soft capsule is bioequivalent to Airtal^(™) tablet.

分割最適電力潮流計算의 改善에 관한 硏究

李鳳容,金正勳 弘益大學校 1981 弘大論叢 Vol.13 No.-

Nonlinear optimization models for econmoic power system operations are particularly attractive, because, in these models, active as well as reactive power can be taken into consideration so that more saving in fuel cost can be expected and voltage-reactive power control can simultaneously be achieved. However, speed and reliability of convergence remain as the main obstacles to be considered in real-time power systems. To overcome the above-mentioned shortcoming, Newton-Raphson decoupled optimal load flow was extended and convergence characteristics were improved in this study. The results showed an acceptable convergence with which the real-time operation is possible. Further, it is noted that voltage-reactive power control could effectively be performed. The savings to the total system fuel cost were 0.7%, or to equivalent fuel cost for transmission loss 30%, which amounts to 6 billion [won] annually with assumed load level. 1. 序 論 2. 分割最適潮流計算 要約 3. 水火力協調系統에서의 考慮 4. 한 母線에 連結된 多數機의 境遇 5. 電壓과 變壓器의 탭 6. 潮流計算의 收????特性改善 7. 燃料費 最少化 過程의 收????特性改善 8. 實規模系統에의 適用結果 9. 結 論 Nonlinear optimization models for econmoic power system operations are particularly attractive, because, in these models, active as well as reactive power can be taken into consideration so that more saving in fuel cost can be expected and voltage-reactive power control can simultaneously be achieved.

표준균주를 포함한 230여개의 김치유래 젖산균에 대한 균체지방산(FAMEs)을 분석하였다. FAMEs profiles는 Euclidian Distance 17.5에 의해 7개의 Major Cluster와 1개의 Single Cluster로 나뉘어졌다. 이중 A, B, C 및 Cluster는 Leuconostoc속으로 분석되어졌고, F는 Lactobacillus속으로 분석되어졌다. 그리고 E와 G cluster는 두개의 Genus가 혼재되어 나타났으며 보충적인 연구가 필요하다. 앞으로 김치유래 젖산균의 균체지방산 분석결과를 기반으로 한 데이타베이스에 95가지 탄소원을 이용하는 수치분류학적 접근방법 및 Pyrolysis Mass Spectrometry 등의 화학적 분석 방법과 분자친화적 연구를 통한 종합적 분류정보 체계가 갖추어지면 젖산균의 신속, 정확한 동정 및 연구에 활발히 이용되어질 것이다. Two hundreds and thirty lactic acid bacteria, mostly isolated from Kimchi, including type strains were sued for analysis of cellular fatty acids. The 230 test strains were recoverd in 7 major and 1 single clusters defined a Euclidian distance of 17.5. These aggregate taxa were equivalent to the genus Leuconostoc (aggregate group A, B, C and D), and the genera Leuconostoc and Lactobacillus (aggregate group G). It is concluded as evident that FAMEs (Fatty Acid Methyl Esters) profile of cell can be used as a criterion in classification of lactic acid bacterial from kimchi. Additional comparative taxonomic studies need to be carried out on well chosen representative strains to determine the most appropriate methods of value.

The Wittig reactions of triarylphosphonium ylides with various carbonyl compounds under high pressure were carried out to investigate its effect on the cis-trans stereochemical outcome. Generally, the cis-stereoselectivities at atmospheric pressure are known to be resulted from smaller steric hindrance of α-carbon of carbonyl group with hydrogens of phenyl residue of triphenylphosphonium ylide and in oxaphosphetane intermediate stage. Thus, the steric interactions between triphenylphosphonium ylide and carbonyl compounds in the transition state can be maximized. And, the reactions of semistabilized ylide and stabilized ylide at atmospheric pressure generate mainly thermodynamically more stable trans-alkane after formation of betaine intermediate. The reactions at high pressure, however, can generate cis-alkene more exclusively through oxaphosphentane intermediate,directly without the formation of betaine intermediate by reducing distance between ylide and carbonyl compound. Reaction between benzyl triphenylphosphonium ylide, a semistabilized ylide, and butyraldehyde at atmospheric pressure gave cis-1-phenyl-1-pentene with 34/66 of Z/E stereoselectivity, but when pressurized at 10000 bar, cis-alkene with 69/31 the Z/E ratio was excellently yielded than trans-alkene. In the case of Wittig reaction of ethoxyacetyl triphenylphosphonium ylide, a stabilized ylide, with butyraldehyde, Z/E stereoselectivity at 10000 bar was inversed in contrast to atmospheric pressure.

Tissue markers of cellular proliferation have been utilized as prognostic indicators in tumors of the central nervous system. Nucleolar organizer regions represent transcriptionally active sites of ribosomal deoxyribonucleic acid and can be identified by a simple argyrophilic technique. The authors describe a standardized approach to the assessment of these argyrophilic nucleolar organizer regions(AgNORs) in 25 astrocytomas(including 6 glioblastomas), 6 oligodendrogliomas and 1 xanthochromic astrocytoma, which were also estimated in association with 2-year survival post-operatively. Appropriate sections were silver stained and AgNORs were counted in 1000 cells. In cases of astrocytoma, the mean AgNORs/cell count of group survived more than 2 years after operation was significantly different from that survived less than 2 years : 1.93±1.13 vs. ≥ 4.79±3.90. And the mean AgNORs/cell count was 1.53±0.32 in low grade astrocytoma. 2.03±0.59 in grade Ⅲ astrocytoma, and ≥6.64±3.77 in grade Ⅳ astrocytoma. Among the patients with the same grade astrocytoma, the mean AgNORs/cell count was lower in the cases of long survival rather than short survival. The assessment of AgNORs can be easily performed by any surgical pathology laboratory without specialized equipment. It may be used as a valuable and independent prognosticator of biological behavior in cases of astrocytoma.
