The substitution reactions of methyl para-substituted benzenesulfonates with nucleophils such as methanol, pyridine and sodium methoxide in methanol at 30℃ were investigated by conductometry and spectrometry in order to understand the reactivityselectivity relationship. The Hammett plot of kinetic data showed ρ values of 1.29, 1.18, 1.04 for the nucleophilic substitution reaction with methanol, pyridine and methoxide, respectively. Taking ρvalues as a selectivity parameter of the nucleophiles and considering the results with a series of nucleophiles showing the increase of reactivity in that order, there seems to be an inverse relationship between reactivity and selectivity.

In this paper, a new shape feature extraction method of the objects using surface curvatures is described. First, the values of the H & K are calculated from range data as given input. Then objects are assigned in the form of 8 primitives by the signs of the H & K values. But existing methods have the difficulties with the complex object. Therefore, We propose the method for the complex primitives such as cone ridge and cone valley. Finally, the effectiveness of this paper is demonstrated by several experiment.

This study was undertaken to investigate the effects of placenta on the toxicity of KC-400 in rabbits. Rabbits were treated with 800㎎ of KC-400 in 2㎖ olive oil via IP injection intermittently day after day for a week and were successively administered with 2㎖ of the placenta extracts via I. V. injection twice a day after day as well as with the placenta extracts with 50 ㎎ of vitamin C as well. The results obtained in this experiment were as follows: 1. When the experimental animals were treated with human placenta, there wasn't any alteration of the hematochemical indicators such as RBC, WBC, Hgb, Het, serum Cholesterol, s-GOT, s-GPT, serum Alkaline Phosphatase and Total lipids in serum. 2. According to the experiment of PCB poisoning, while s-C, s-GPT, s-ALP, and s-TL were increased, RBC, WBC, Hgb and Het were decreased during the experimental periods respectively. 3. The placenta extracts normalized the hematochemical indicators of the PCB poisoned animals after one day treated by the placenta extracts. 4. The combined treatment with the placenta extracts and vitamin C was the same effect as the single placenta treatment only; they were not significant in the t-test. 5. The placenta extracts inhibited the serum tyrosinase activity of the rabbits which was induced by PCB in vivo and in vitro respectively. By the combined treatment with the placenta extracts and vitamin C, the activity of tyrosinase was remarkably inhibited in comparison with the single treatment with the placenta alone.

Acute myocarditis complicating coronary vasospasm after smallpox vaccination is very rare complication that can be generally developed within less than 30 days after vaccination. Clinically and biochemically, this disorder is often mimic and highly suggestive of acute myocardial infarction. We report 21 years old man that had a history of a smallpox vaccination 3 weeks ago and prodromal symptoms(fever, malaise etc) a few days ago. hIe visited to our hospital because of abrupt onset of severe substernal chest pain, dyspnea and diaphoresis. At admission, electrocardiography was ST elevation in lead Ⅰ, aVL, V4, V5, and V6. The CK-MB level was 68 U/L, LDH level was 760 U/L, Troponin-Ⅰ was 24.64 ng/㎖, and Troponin-T was positive. 2D-echocardiograpy was normal left ventricular function, Clinically we presumed this disorder as acute myocardial infarction and we promptly performed the coronary angiography and revealed focal spasm in distal left coronary artery territory without critical stenosis in both coronary arteries. We diagnosed this disorder as coronary vasospam complicating acute myocarditis that is different with acute myocardial infarction, and we prescribed nitroglycerin and nifedipine. After discharge, he is now well without any symptoms and has been following up monthly at our outward department for 6 months.

켈빈파란 회전계의 북반구에서 육지를 오른쪽에 두고 해안선을 따라 이동하는 파이다. 이 켈빈파를 가시화하기 위해 밀도차를 갖는 두 층의 유체를 만들고 경계면에 생기는 내부캘빈파를 가시화하여 변화를 관찰하였다. 지금까지는 해안가에서 나타나는 밀물과 썰물을 단순히 달의 인력으로 인한 조석으로만 생각했었는데, 본 실험을 통하여 그것이 지구자전의 영향을 받아 회전하는 조석파임을 알게되었다. Kenvin wave moves along the shoreline from the Northern hemisphere of rotating system in right of the land. Yeu observe s veriety for the visibity of it, we make two layers to have divergence of density, then it is visible the interior of Kelvin wave in a boundary plane. You thought simply the ebb and flow of the tide that they was the tidal movement to be due to the gravitation of the moon on the shore. But we know that Kelvin wave is rotating tide wave affected by revolution of the earth.

기존의 특수건강진단과 작업환경측정을 통한 직업병 관리가 진폐증, 소음성난청 등의 소수 특정질환에 국한되고 실제 직업병 발생 규모 파악이나 신종 직업병의 발견에 한계를 보인다는 사실은 산업의학전문가들 사이에서도 공감을 이루고 있다. 미국과 영국 등에서의 직업성질환 감시체계에 대한 경험은 우리 나라의 직업성질환 감시체계 구축에도 새로운 자극제가 되면서, 1998년이후 인천, 대전, 여천, 구미, 부울경 지역에서 지역 직업성질환감시체계를 산업보건관리의 중요한 시스템으로 구축하려는 노력이 확산되고 있다. 새로이 구축되어지는 이들 지역 직업성질환 감시체계는 감시하고자 하는 대상질환, 활용 가능한 인적자원 및 자료원, 지역 의료체계의 특수성 등에 따라서 목적과 방법을 달리하면서 독특한 형태로 발전을 하고 있다. 각 지역단위 감시체계들이 그 상황에 맞게 독특한 목적과 전략들을 발전 시키면서도, 향후 발전할 국가적인 차원의 직업성질환 감시체계 구축을 위하여 직업성질환 감시의 기본 전략 등을 공유하는 등의 노력이 필요하다. 환례 정의 및 기본적인 등록 서식의 공유, 직업성질환 감시 자료원의 발굴, 공동의 정보 네트워크 및 직업성질환 감시 데이터베이스 구축 등 직업성질환 감시활동을 지원하기 위한 여러 기초 인프라 구축에 힘을 모아야 할 것이다. 우리 나라에서 직업성질환 감시체계를 성공적으로 구축하기 위해서는 수집된 자료의 질 관리를 위한 직업성질환 감시의 원칙 제정과 감시 전략의 공유 등이 필요하며, 전국적인 직업성질환 감시체계의 하부구조라고 할 수 있는 지역감시체계의 기초 토대 마련과 강화작업이 절실하게 필요하다.

This study was to test the importance of patterns identification (PI) and the effectiveness of Hwangryunhaedogtang (Huanglianjiedutang) (HT) treatment for patients with post stroke pathological laughter (PL). Fourteen subjects were enrolled. Eight subjects diagnosed with Yang Excess patterns (YEP) were assigned into group A and 6 subjects who had no YEP to group B. HT was administrated 3 times a day for 14 days to both groups. The duration of PL at one time. the frequency of PL in a day, and pathological laughter scale (PLS) were the primary outcome measures. Barthel index (BI) was the secondary outcome measure. The duration and the frequency of PL in group A were significantly decreased from 10.88 ± 4.67 to 6.63 ± 4.07 sec and from 6.38 ± 2.72 to 3.00 ± 1.77 times. respectively (p = 0.01) after 14 days administration of HI. PLS in group A was also significantly lowered from 9.13 ± 1.73 to 4.75 ± 0.71 points (p = 0.01). However, significant differences were not observed in BI in group A and in the primary and secondary outcome measures in group H. The duration and the frequency ofPL and PLS were more markedly reduced in group A than in group B(p = 0.01. 0.02, and < O.O1, respectively), These results suggested that HT could be effective on subjects with post stroke PL diagnosed as YEP and PI, that prescription of herbal medications to such patients should be considered.

Objectives :Ginkgo-Chunghyul-dan (GCHD) is newly developed herbal medicine to prevent and treat stroke. In this study, we investigated whether the GCHD had antioxidant activity and anti-platelet aggregation effect in vitro and hypolipidemic activities in vivo. Methods :Anti-oxidant activity of GCHD was measured using the Blois method, anti-platelet effect of GCHD was assessed by the Born method, and hypolipidemic activities of GCHD were evaluated in corn oil- or Triton WR-1339-induced and cholesterol-fed rats. Results :GCHD showed anti-oxidant activity in the study inhibiting the formation of 1-diphenyl-2-picrylhydrazyl radicals and xanthine oxidase activity. GCHD had anti-platelet aggregation activity. GCHD significantly lowered total cholesterol (TC), triglyceride (TG), and low density lipoprotein cholesterol (LDL-C) in high cholesterol diet and Triton WR-1339 induced model TG in corn oil-induced model. GCHD had no acute toxicity at a single dosage. Conclusion : These results suggest that GCHD has the potential to treat hyperlipidemia and stroke.
