The paper is proposed maximum torque control of IPMSM drive using adaptive learning mechanism-fuzzy neural network (ALM-FNN) and artificial neural network(ANN). For each control mode, a condition that determines the optimal d-axis current $i_d$ for maximum torque operation is derived. The proposed control algorithm is applied to IPMSM drive system controlled ALM-FNN and ANN, the operating characteristics controlled by maximum torque control are examined in detail. Also, this paper is proposed the analysis results to verify the effectiveness of the ALM-FNN and ANN.

목적 : 용혈성 요독 증후군은 서구에서 영아 및 소아의 가장 흔한 급성 신부전의 원인으로 알려져 있으나 국내에서는 발생 빈도가 적다. 이 질환은 아시아 및 일본지역에서는 비교적 드문 질환이었으나 최근 몇년 동안 출혈성 설사를 동반한 용혈성 요독 증후군이 급속히 증가 하고 있다. 이에 저자들은 최근 본원에서 경험한 5례를 대상으로 임상적인 특성과 경과를 관찰 하였다. 방법 : 1996년 1월부터 1996년 12월까지 삼성 서울 병원 소아과에 입원하여 용혈성 요독 증후군으로 진단 받고 치료한 5례의 소아를 대상으로 후향적으로 병록 검토를 시행하였다. 결과 : 1) 발병 당시 연령은 3세 이하가 3례, 9세이상이 2례였다. 2) 계절적 분포는 모든 예에서 여름과 가을에 발생하였고, 전구 증상이 있기전에 여행한 경험이 있는 경우가 3례, 오염된 지하수나 약수를 마신 경력이 있는 경우가 4례 였다. 3) 임상 증상으로는 전신 부종 5례, 핍뇨 4례, 무뇨 2례, 육안적 혈뇨 1례였다. 소화기계 증상은 설사가 전예에서 있었고 1례에서 급성 충수염으로 오인 하여 개복 수술 받았다. 4) 혈액 및 배변 배양 검사에서 동정된 균은 없었다. 5) 무뇨증이 2주일 이상 지속된 2례에서 경피적 신생검이 시행 되었으며, 1례는 주로 사구체를 침범한 혈전성 미세 혈관증을 보였고, 1례는 신부전으로 이행된 국소적 신피질 괴사와 사구체 경화가 있는 만성 괴사성 사구체 신증 소견을 보였다. 6) 임상적 예후는 완전 회복된 경우가 4례, 고혈압이 동반된 만성 신부전이 1례였고, 이 1례에서 시행한 복부 단층 촬영상 전형적인 신피질 괴사 소견과 담석이 관찰 되었다. 결론 : 유행성이면서 예후가 좋은 전형적인 용혈성 요독 증후군은 주로 서구에서 많이 보고되어 왔으나, 최근 몇년 동안 일본 등 아시아 지역에서도 급속히 증가 추세를 보이고 있어, 국내에서도 출혈성 설사를 동반한 용혈성 요독 증후에 대한 면밀한 임상적 관찰이 필요할 것으로 사료된다.

Maek Kyoung(Mai Jing, 脈經) is the first chinese specialized book of diagnostics written by Wang Hee(Wang xi, 王熙) from Seo Jin(xi jin, 西晉). He assorted the contents with pulse and medical examination from Nae Kyoung(nei jing, 內經), Nan Kyoung(nan jing, 難經), Sang Han Ron(shang han lun, 傷寒論) and Jung Jang Kyoung(zhong cang jing, 中藏經). And united with his own research, he explains medical examination and the way of talking the pulse by classifying into entrance and class. Maek Kyoung(Mai Jing, 脈經) was imported Korea by Ji Chong(zhi cong, 知聰) AD 561, and he passed through Ko Ku Ryeo(gao gou li, 高句麗) with Nae Wei Jeon(nei wai dian, 內外典), Yak Seo(yao shu, 藥書), Myung Dang Do(ming tang tu, 明堂圖) and Maek Kyoung(Mai Jing, 脈經) to be naturalized in Japan. This treatise make a special study of the second volume of the Maek Kyoung. It consists of the four chapters: Pyoung Sam Kwan Eum Yang E Sip Sa Ki Maek Je II(平三關陰陽二十四氣脈第一), Pyoung In Young Sin Mun Ki Ku Jeon Hu Maek Je E(平人迎神門氣口前後脈第二), Pyoung Sam Kwan Byoung Hu Byoung Chi Eui Je Sam(平三關病侯幷治宜第三), and Pyoung Gi Kyoung Pal Maek Byoung Je Sa(平寄經八脈病第四). Bi Geup Choun Geum Yo Bang(備急千金要方) and Eui Hak Ip Mun(醫學入門) quoted from the contents in the second volume of Maek Kyoung, and Bin Ho Maek Hak(瀕湖脈學), Gi Kyoung Pal Maek Go(奇經八脈攷) and Maek Eo(脈語) extracted from contents in the second volume of the Maek Kyoung and requoted from this contents. Contents in the second volume of the Maek Kyoung have very valuable data like that, but the literature on this subject in the form of a treatise has not been yet in Korea. So I hope this study will be useful to develope Diagnostics by correcting translation and interpretation and fixing wrong translation.

Experts of Sasang Constitution Medicine of Traditional Korean Medicine have classified stroke patients with four types of Sasang constitutions in their clinical practice and some types of Sasang constitutions have been regarded as risk factors of stroke, but this is uncertain because there were no evidences by large scale of prospective studies. The purpose of this was to study the association between strokes and Sasang constitutions. Case-control study has been conducted to the patients admitted to the research hospitals. The patients were confirmed stroke by brain MRI or CT scans and recruited from May 2003 to August 2005. The subjects who met the requirement of inclusion and exclusion criteria were 108 patients as the cases and 107 as healthy controls. Data collection has been performed by the trained specialists majoring neurologists through interviews, physical examinations, and laboratory testes. No statistical significance was obtained between the strokes and Sasang constitutions, yet Taeumin, and Soyangin types showed a trend of increase in the incidence of strokes as compared with Soeumin. To acquire more concrete data on this theme, we need further and large scale of prospective researches.

화석연료의 고갈 문제로 인하여 다양한 대체에너지가 개발 중이며 본 연구에서는 바이오에탄올 연구의 초석으로 사용하기 위해 곤충의 효소를 연구하였다. 북방수염하늘소(Monochamus saltuarius Gebler)가 지닌 cellulase (MsGHF45) 유전자를 Kluyveromyces lactis에 형질전환 시켰다. 형질전환 된 효모는 활성이 있는 cellulase 효소를 성공적으로 생산하였다. 재조합 MsGHF45의 분자량은 SDS-PAGE와 western blot을 통하여 확인하였다. 효소의 활성은 기질로써 carboxymethyl cellulose를 첨가한 native-PAGE를 통해서 검증하였다. 효소 활성의 최적조건을 알아본 결과, pH는 5에서, 온도는 $40^{\circ}C$에서 나타났다. 바륨이온($Ba^{2+}$)과 철이온($Fe^{2+}$)은 효소활성을 저해하지 않았으나, 칼슘이온($Ca^{2+}$), 코발트이온($Co^{2+}$), 구리이온($Cu^{2+}$), 수은이온($Hg^{2+}$), 마그네슘이온($Mg^{2+}$), 망간이온($Mn^{2+}$) 그리고 아연이온($Zn^{2+}$)은 활성을 저해하였다. 특히, 수은이온은 효소활성을 66.5% 감소시켰다. 본 연구는 다양한 효소를 이용한 biofuel 연구에 참고자료로 사용될 것이다.

In this paper, a new electromagnetic circuit is proposed for an optical pickup actuator with high sensitivity. Contrary to those of conventional actuators, the proposed circuit has two focusing coils which are diagonally placed at the front and rear of a moving part. The configuration which makes the effective length of the focusing coil longer and the moving part lighter, is helpful in increasing the sensitivity of the actuator. However, the asymmetry of the moving part by two focusing coils causes flexible node vibrations in quite low frequency range. This paper shows that the design modification of the moving part for the reconfiguration of mass moment of inertia can reduce the mode vibrations.

The substance 0116p, which exhibits cytotoxicity against human macrophage cell line THP-1, was isolated from a mycelial extract of Streptomyces scabiei subsp. chosunensis M0137. The cytotoxic substance was purified by Diaion-HP2O adsorption, solvent extraction, Sephadex LH-20 column chromatography, and silica-gel column chromatography. The molecular formula is C$\_$19/H$\_$38/O$\_$2/ (MW301.10) based on elemental and spectrometric analysis. It was identified as nonadecanoic acid by NMR spectral data. It exhibits cytotoxic activities in various human cancer cell lines, including A549, SK-OV-3, SK-MEL-2 and HCT-15. In addition, 0116p also inhibits IL-12 production in lipopolysaccharide-activated macrophages.

The purpose of this case was to report the effect of Korean medical treatment for patient with pleural effusion due to congestive heart failure. The patient was treated with herbal medicine(Cheongsingeonbi-tang) and acupuncture. The effect of treatment was evaluated by chest X-ray, New York Heart Association(NYHA) functional classification, and Hugh-Jones classification. After 3 weeks of treatment, the amount of pleural effusion was decreased and NYHA class, Hugh-Jones grade were improved. NYHA functional classification improved class III to II and Hugh-Jones classification changed grade IV to II. This result suggests that herbal medicine(Cheongsingeonbi-tang) and acupuncture treatment might have an effect on patient with pleural effusion due to congestive heart failure.
