  • Two objectives can be pursued simultaneously with the ${\delta}$ control of a single-phase electric spring (ES). These objectives are the stabilization of the voltage across the critical load (CL) of a power system, and the achievement of a specific functionality similar to the pure compensation of reactive power or the correction of the power factor. However, existing control systems implementing the ${\delta}$ control do not cope with non-ideal operating conditions, such as line voltage distortions, and exhibit a somewhat sluggish regulation of the CL voltage. In an effort to improve both the steady-state and transient performances of an ES power system, this paper proposes implementing the ${\delta}$ control by means of a control system built up on the repetitive control and assisted by state feedback with pole assignment. This paper starts by analyzing the dynamics of an ES power system in terms of its poles and zeros. After that, a reduced second-order model of the dynamics is formulated to avoid a notch filter in the pole assignment. A repetitive control for an ES power system is then designed to meet the two above mentioned objectives. Experimental tests carried out on a laboratory setup demonstrate the effectiveness of the proposed control system in significantly improving the ES power system performance, while reaching the two objectives. In particular, the tests outline the large mitigation of harmonics in the CL voltage under line voltage distortions and its fast stabilization action.

  • Aconitine has much Heat and Toxicity in its property, so many consideration is needed during its use. And there are many contraindications of its use. In the book of Dongyisusebowon, it has to be used when Soeumin has extreme Cold accompanied by Heat of deficiency type. In this case report, a 84 year-old male patient who had taken drugs containing Aconitine had severe Yin-Deficiency-Midday-Fever(陰虛午熱). And he had been treated with Sukjiwhanggosamtang(熟地黃苦參湯) and Dokwhaljiwhangtang(獨活地黃湯). Four conclusions can be made through this case. 1. Soyangin(少陽人) patients may have many side effects or adverse effects when they take drugs containing Aconitine even at a little volume. 2. Soyangin may have chest discomfort when they are constipated. This patient also complained chest discomfort after stroke and toxicosis of Aconitine. 3. Between Sukjiwhanggosamtang(熟地黃苦參湯) and Dokwhaljiwhangtang(獨活地黃湯), Sukjiwhanghosamtang is more effective for this patient who has been skin psoriasis and lower diabetes(下消) for a long time. 4. Although Sukjiwhanghosamtang does not include any antidote drug of Aconitine, it may be used only when defferenciation of symdrome is proper on Sasang Constituional Medicine.

  • Myeong(明) Dynasty Period put together clinically various medical theory in Song(宋) Dynasty and Geum-Won(金元) age, organized medical system. They have been developed in theory, which thought of Byeonjeungronchi(辨證論治) more important, and clinical part which included diagnosis, therapy, prevention. In that age reactional medical thought was in fashion because of affect of Ihak(理學), therefore pediatrics have been affected from them. Especially, looking at the symptom of Byeonjeungronchi doctors, Manjeon(萬全), Nobaeksa(魯伯嗣), Wangdaeryun(王大綸), Wanggeungdang(王肯堂), Nuyeong(樓英) had succeed to Jeoneul(錢乙)' the five viscera Byeonjeung(辨證) system. Manjeon advocated Samyuyeosabujokron(三有餘四不足論) about Jangbu(臟腑) and organized the curative principle about Ojangheosil(五臟虛實). Gupyeong(寇平), commented on diagnosis of five viscera and classification of disease of five viscera. Wangdaeryun in the close of Myeong Dynasty Age explained main pulse, pulse of illness in detail according to weakness or strength of five viscera, pathological or physiological features of five viscera and Saenggeuk(生克) relation of Ohaeng(五行) in the book of "Yeongdongryuchwe(嬰童類萃)". Wanggeungdang and Nuyeong had organized system of argument which classified disease as a result of symptom of five viscera. "Yugwajeungchijunseung(幼科證治準繩)" and "Uihakgangmok(醫學綱目) Soabu(小兒部)" had been written by this principle. Nobaeksa had arranged the principle of cure about five viscera and explained method of common use about each organ's disease. Besides, Seolgi(薛己), Janggyeong-ak(張景岳), insisted about Myeongmun(命門) because he thought of Bisin(脾腎) of children and vigor by nature importance. Seolgi had applied and used very well Bojung-ikgitang(補中益氣湯) based on Idongwon(李東垣)'s Biwiseol(脾胃說) and controled and helped spleen and stomach. At the same time, he took a serious view about supplementing children's Sin-gi(腎氣) according to so many spleen and stomach disease was fallen because they couldn't make warm the spirit of Jungju(中州), result of weakening Hwa(火) of Myeongmun. Also Janggyeong-ak took a serious view strengthen of Bisin, so he assorted and used Insam(人蔘) and Buja(附子) to supplement children's weaken energy in kidney Jeonggi(精氣).

  • Objective : This study reviews the recent trend of oriental medical prescription research. The data examined are the articles published in the Korean Journal of Oriental Medical Prescription from 1990 to 2009. Method : The data are retrieved through the internet database Oriental Medicine Advanced Searching Integrated System (OASIS) and the collection of the Korean Journal of Oriental Medical Prescription. The number of articles examined is 385, published in 25 volumes of the journal. This study examines the nature of the articles, research methods, subjects, and author information. Research subjects are sorted out by the OASIS key words for the articles published before 1999, and by key word indexes cited in the abstracts for the articles published sinceafter. Results : Among the 385 articles collected, 206 are research articles, 143 philological articles, 35 case studies, and 1 special contribution. A majority of research articles are experimental studies (199 articles or 96.6%), while clinical reports (5 articles or 2.43%), and others studies (2 articles) occupy a small portion. Most of experimental studies (183 articles or 91%) examine the effectiveness of certain prescriptions or treatments. Among the effectiveness studies, 114 articles (62.3%) employ in vivo experiment design, 52 articles (28.42%) in vitro experiments, and 17 articles (9.29%) both in vivo and in vitro experiments. In terms of research subject, the most frequently indexed key words are hepatotoxicity among diseases (9 articles), Bojungikgitang (Bu-Zhong-Yi-Qi-Tang) among prescriptions (10 articles), Buja (Acontii Tuber) among meteria medica (4 articles), immunity and anti-oxidation among efficacy terminology (6 articles each), and Donguibogam(東醫寶鑑) among references in the key words (25 articles). Universities are the main affiliation of authors (76.42%), followed by university hospitals (6.71%), non-academic research institutes (5.55%), local clinics (4.67), academic research institutes (2.81%), hospitals (2.38%), and others (1.44%). The most affiliated institute of the first and correspondent authors is Wonkwang University. In terms of authorship, co-authorship outnumbers sole-authorship by 82.08% to 17.92%.

  • Objectives : This study was conducted to analyze the single dose toxicity of Mecasin (Gami-Jakyak Gamcho buja Decoction) herbal acupuncture administered in the vein of Sprague-Dawley rats. Methods : All experiments were performed at the Medvill, an institution licensed to conduct nonclinical studies, under the Good Laboratory Practice (GLP) regulations. Sprague-Dawley rats were chosen in this pilot study. In the experiment, Sprague-Dawley rats were divided into four groups of five male and five female animals per group. Doses of Mecasin herbal acupuncture, at 0, 500, 1,000, and 2,000 mg/kg, were given to the experimental groups, and a dose of normal saline solution, at 2 ml/kg, was administered to the control group. Mecasin herb acupuncture and normal saline were injected into the vein at once, and we observed mortality, clinical signs, weights, and gross findings for 14 days after injection. This study was conducted under the approval of the Institutional Animal Ethics Committee. Results : There is no death or abnormality in any of the four groups. All groups put on weights favorably. There are no significant gross findings in necropsy examinations. Conclusions : The above results showed that intravenous injection of 500-2,000 mg/kg of Mecasin herb acupuncture did not cause any changes in weight or, in the results of necropsy examinations, in mortalities. Therefore, the toxicity of Mecasin herb acupuncture was not confirmed, and the presumptive lethal dose of Mecasin herb acupuncture was higher than 2,000 mg/kg. The outcomes suggest that treatment with Mecasin herbal acupuncture is relatively safe. Further evaluations on this subject are needed to yield more concrete evidence.

  • This study was performed to investigate the cause, symptom, treatment, medicine of Wei symptom through the literature of oriental and western medicine. The results obtained were as follows: 1. Wei symptom is the symptom that reveals muscle relaxation without contraction and muscle relaxation occures in the lower limb or upper limb, in severe case, leads to death. 2. Since the pathology and etiology of Wei symptom was first described as "pe-yeol-yeop-cho"(肺熱葉焦) in Hung Ti Nei Ching(黃帝內經), for generations most doctors had have accepted it. but after Dan Ge(丹溪), it had been classified into seven causes, damp-heat(濕熱), phlegm-damp(濕痰), deficiency of qi(氣虛), deficiency of blood(血虛), deficiency of yin(陰處), stagnant blood(死血), stagnant food(食積). Chang Gyeng Ag(張景岳) added the cause of deficiency of source qi(元氣). 3. The concept of "To treat Yangming, most of all"(獨治陽明) was emphasized in the treatment of Wei symptom and contains nourishment of middle warmer energy(補益中氣), clearance of yangming-damp-heat(淸化陽明濕熱). 4. Since Nei-ching era(內經時代), Wei and Bi symptom(痺症) is differenciated according to the existence of pain. After Ming era(明代) appeared theory of co-existence of Wei symptom and pain or numbness but they were accepted as a sign of Wei symptom caused by the pathological factor phelgm(痰), damp(濕), stagnancy(瘀). 5. In the western medical point of view, Wei symptom is like paraplegia, or tetraplegia. and according to the causative disease, it is accompanied by dysesthesia, paresthsia, pain. thus it is more recommended to use hwal-hyel-hwa-ae(活血化瘀) method considering damp-heat(濕熱), qi deficiency of spleen and stornach(脾胃氣虛) as pathological basis than to simply differenciate Wei and Bi symptom according to the existence of pain. 6. The cause of Gullian-Barre syndrome(GBS) is consist of two factors, internal and external. Internal factors include asthenia of spleen and stomach, and of liver and kidney. External factors include summur-damp(暑濕), damp-heat(濕熱), cold-damp(寒濕) and on the basis of "classification and treatment according to the symptom of Zang-Fu"(臟腑辨證論治), the cause of GBS is classified into injury of body fluid by lung heat(肺熱傷津), infiltration of damp-heat(濕熱浸淫), asthenia of spleen and kidney(脾腎兩虛), asthenia of spleen and stomach(脾胃虛弱), asthenia of liver and kidney (肝腎兩虛). 7. The cause of GBS is divided by according to the disease developing stage: Early stage include dryness-heat(燥熱), damp(濕邪), phlegm(痰濁), stagnant blood(瘀血), and major treatment is reducing of excess(瀉實). Late stage include deficiency of essence(精虛), deficiency with excess(虛中挾實), and essencial deficiency of liver and kidney(肝腎精不足) is major point of treatment. 8. Following is the herbal medicine of GBS according to the stage. In case of summur-damp(暑濕), chung-seu-iki-tang(淸暑益氣湯) is used which helps cooling and drainage of summer-damp(淸利暑濕), reinforcement of qi and passage of collateral channels(補氣通絡). In case of damp-heat, used kun-bo-hwan(健步丸), In case of cool-damp(寒濕), used 'Mahwang-buja-sesin-tang with sam-chul-tang'(麻黃附子細辛湯合蓼朮湯). In case of asthenia of spleen and kidney, used 'Sam-lyeng-baik-chul san'(蔘笭白朮散), In case of asthenia of liver and kidney, used 'Hojam-hwan'(虎潛丸). 9. Following is the herbal medicine of GBS according to the "classification and treatment according to the symptom of Zang-Fu"(臟腑辨證論治). In the case of injury of body fluid by lung heat(肺熱傷津), 'Chung-jo-gu-pae-tang'(淸燥救肺湯) is used. In case of 'infiltration of damp-heat'(濕熱浸淫), us-ed 'Yi-myo-hwan'(二妙丸), In case of 'infiltration of cool-damp'(寒濕浸淫), us-ed 'Yui-lyung-tang', In case of asthenia of spleen, used 'Sam-lyung-bak-chul-san'. In case of yin-deficiency of liver and kidney(肝腎陰虛), used 'Ji-bak-ji-hwang-hwan'(知柏地黃丸), or 'Ho-jam-hwan'(虎潛丸). 10. Cervical spondylosis with myelopathy is occuered by compression or ischemia of spinal cord. 11. The cause of cervical spondylosis with myelopathy consist of 'flow disturbance of the channel points of tai-yang'(太陽經兪不利), 'stagnancy of cool-damp'(寒濕凝聚), 'congestion of phlegm-damp stagnant substances'(痰濕膠阻), 'impairment of liver and kidney'(肝腎虛損). 12. In treatment of cervical spondylosis with myelopathy, are used 'Ge-ji-ga-gal-geun-tang-gagam'(桂枝加葛根湯加減), 'So-hwal-lack-dan-hap-do-hong-eum-gagam(小活絡丹合桃紅飮加減), 'Sin-tong-chuck-ue-tang-gagam(身痛逐瘀湯加減), 'Do-dam-tang-hap-sa-mul-tang-gagam'(導痰湯合四物湯加減), 'Ik-sin-yang-hyel-guen-bo-tang'(益腎養血健步湯加減), 'Nok-gakyo-hwan-gagam'(鹿角膠丸加減). 13. The cause of muscle dystropy is related with 'the impairement of vital qi'(元氣損傷), and 'impairement of five Zang organ'(五臟敗傷). Symptoms and signs are classified into asthenia of spleen and stomach, deficiency with excess, 'deficiency of liver and kidney'(肝腎不足) infiltration of damp-heat, 'deficiency of qi and blood'(氣血兩虛), 'yang deficiency of spleen and kidney'(脾腎陽虛). 14. 'Bo-jung-ik-gi-tang'(補中益氣湯), 'Gum-gang-hwan'(金剛丸), 'Yi-gong-san-hap-sam-myo-hwan'(異功散合三妙丸), 'Ja-hyel-yang-gun-tang'(滋血養筋湯), 'Ho-jam-hwan'(虎潛丸) are used for muscle dystropy. 15. The causes of myasthenia gravis are classified into 'insufficiency of middle warmer energy'(中氣不足), 'deficiency of qi and yin of spleen and kidney'(脾腎兩處), 'asthenia of qi of spleen'(脾氣虛弱), 'deficiency of qi and blood'(氣血兩虛), 'yang deficiency of spleen and kidney'(脾腎陽虛). 16. 'Bo-jung-ik-gi-tang-gagam'(補中益氣湯加減), 'Sa-gun-ja-tang-hap-gi-guk-yang-hyel-tang'(四君子湯合杞菊地黃湯), 'Sa-gun-ja-tang-hap-u-gyi-eum-gagam'(四君子湯合右歸飮加減), 'Pal-jin-tang'(八珍湯), 'U-gyi-eum'(右歸飮) are used for myasthenia gravis.
