In this paper, we present the global minimization condition by an informal analysis of the Langevine competitive learning neural network. From the viewpoint of the stochastic process, it is important that competitive learning guarantees an optimal solution for pattern recognition. By analysis of the Fokker-Plank equation for the proposed neural network, we show that if an energy function has a special pseudo-convexity, Langevine competitive learning can find the global minima. Experimental results for pattern recognition of handwritten numeral data indicate the superiority of the proposed algorithm.

As an attempt to develop new functional beverage by using medicinal herb, Artemisia capillaris. Therefore we investigate the effect of scopoletin in Artemisia capillaris on vessel and regional cerebral blood flow (rCBF) of rats. Artemisia capillaris extract was significantly decreased vessel constraction and significantly increased rCBF. Artemisia capillaris has often been cited in medical literature for its medicinal effects. Although the Korean Food and Drug Administration indicated Artemisia capillaris as the In-Jin-Sook which was allowed as a food stuff. From the view point of the subjects who eat In-Jin-Sook products, most of them ingested it for a certain pharmacological efficacy rather than as a beverage or a food. According to this facts, we need develop functional foods using In-Jin-Sook. Also scopoletin, get known to smooth muscle relaxation content was 326.13 ug/g. These results demonstrate that Artemisia capillaris has pharmaceutical effects and balanced nutritional contents. In according with Artemisia capillaris has a sufficiency of the terms use of food stuff in functional foods.

We came to the conculsion after considering all of information from many kinds of books on the cause, pathogenesis and treatment of Flaccidity-syndrome. The results were as follows : 1. Flaccidity-syndrome means limb-relaxation due to muscle atony that isn't able to constraction. It's begun as mild degree from extremities, in some cases ended to quadriplegia or expire. 2. Cause factor and pathogenesis of Flaccidity-syndrome is various. After Lung fluid consuption caused by heat-evil was refered in The Yellow Emperor's Canon of Internal Medicine. They were refered as cause factor that Main channel asthenia, excess of sexual intercourse, wetness-evil, heat-evil gets into the interior, asthenia of the spleen and stomach. Since Ming Dynasty, It's classified to wetness-heat evil, wetness-phlegm, deficiency of vital energy, deficiency of blood, deficiency of yin, blood stasis and indygestion, etc. 3. In the view of treatment of Flaccidity-syndrome, Yangming was selected in The Yellow Emperor's Canon of Internal Medicine, and it's been mean to clear away wetness-heat evil located at Yangming. In the method of acupuncture it was same on the base, and many skills have been used that electronic acupuncture, point-injection theraphy, acupuncture point block, catgut implantaion at acupuncture point, cutaneous acupuncture, auriculo-acupuncture and head acupuncture by the through post generation. 4. Flaccidity-syndrome was defined to weak, disuse and non-pain. Beacause it was non-pain, so medicine to expel wind-evil was prevented to use. But through post generation Flaccidity-syndrome has been treated that is able to cause pain or numness as arthralgia-syndrome. Therefore there is tendency that medicine to expel wind-evil is capable within pathological basement of Flaccidity-syndrome in recent. 5. In the view of west-medicine, Flaccidity-syndrome is diplegia or quadriplegia with sensory disorder, muscle atropy in some cases. And there are spinal disease, peripheral nerve disease, muscular disease, nerve-muscle copula disease. The symptoms are able to amyotomia, numness, sensory disorder, pain.

The Mi-Sa(微邪) of the Excessive Liver-Symptoms belongs to the four symptoms, there are meat in eye, edema in cheek, lack of appetite and diarrhea. 3. The Juk-Sa(賊邪) of the Excessive Liver-Symptoms belongs to the only one symptom, this is nosebleeding. 4. The Hu-Sa(虛邪) of the Excessive Liver-Symptoms belongs to the three symptoms, there are scrotum constraction, strain in belly and constipation. 5. The Sil-Sa(實邪) of the Excessive Liver-Symptoms belongs to the twenty eight symptoms, there are red eye, raised eyes(兩眼上?), spitting blood, sternocostal turgid pain, turgidity in belly, drooping testis, vomiting water acid, sickening, belching, confusion, impatience, frequent forgetfulness, headache, giddness, eye pain, deaf, ringing in the ear, feeling inverse, drying mouth, stuffiness sensation in the chest, chest pain, stuffiness sensation in the belly, bellyache, quadriplegia, spasm of extremities, tremor, alternate spells of fever and chills, high fever and strain in muscle. 6. Those symptoms, Red corner of the eye, red face, swelling on the forehead, stiff-neck and back strong, opisthotonos, constracture of the limbs, vomiting yellow bitter water, speech impediment, epilepsy, depression, strong tongue, different thing in throat, fullness and distention of the gastric region, feeling sick and tenesmus, have no connected with the Excessive Liver-Symptoms(肝實證) 7. The Excessive Liver-Symptoms(肝實證) is connected with the ganjabyoung(肝自病) and Hwa(火) which the pathology is, than because Mock(木) is excessive and Mock-Saeng-Hwa(木生火), the ganjabyoung(肝自病) and Sil-Sa(實邪) are many. 8. There are the sixteen symptoms with the exception of The Excessive Liver-Symptoms(肝實證), because supposed that the scholars in medicine included the union syndroms(合病), the combine syndroms(兼病) and the analysis of symptoms(辨證) in The Analysis of Five Visceral Symptoms. 9. During consideration of the symptoms at the above statements, where are many causes by Gan-Pung(肝風), there is difficult of distinction between the excessive Liver-Symptoms(肝實證) and C.V.A(Cerebral Vascular Attack). Because than NaeKyung(內經) distinguished between the excessive Liver-Symptoms(肝實證) and C.V.A., the future medical specialists connected with the excessive Liver-Symptoms(肝實證) and C.V.A.. 10. An appearance of Sang-Hwa(相火) that the liver possessed is divided into an appearance of Hwa(火), there will be making a study att the more necessary. 11. The cuases of each syndroms are consist of the origins of syndroms, its pathology and the positions where the syndroms appeared, I consider that is the various ways how judge the syndroms except the Five Pathogenic Factors(五邪). 12. If more than study will be achieved in all, the new definition will be standed about the Excessive and Deficient Five Visceral Syndroms(五臟虛實證), I consider this will be the foundation data that study the Oriental Medicine and the important data that is a judgement standard of clininc.

Waterpepper is a weed which grows on damp soil. especially near swamps, and in shallow water of ponds and ditches. It Is widespread throughout the country In abundant colonies. In the present experiments, possible toxic effects of waterpepper were investigated in ruminants. Pour cows were fed waterpepper ad libitum or by force in the from of green forage, hay and/or powder, 8 goats were administered in the form of methanol extract, and 4 goats, crude juice, into the lumen. Clinical signs were examined as well as urinalysis, hematology, serum chemical analysis, pH/blood gas analysis and chclinesterase activities following administration of waterpepper. Six goats which were administered the methanol extract or crude juice were sacrificed for pathological examinations., In addition to the clini copathological examinations, the chemical constituents of waterpepper were qualitively analyzed from the methanol extract and the Effects of the waterpepper crude juice were examined on the motility of rabbit duodenum and uterus. It is revealed that waterpepper contains steroids, terpenoids, flavonoids, tannin and essential oils in the methanol extract and nitrates in the crude juice. The crude juice of waterpepper relaxed the rabbit uterine and duodenal smooth muscles. The constraction of duodenum by acetylcholine or BaCl$_2$ were partially inhibited by pretreatment of the crude juice. However, the relaxation of duodenum by the crude juice was not blocked by the pretreatments of phenoxybenzamlne, propranolol, cocaine, reserpine and tetrodotoxin. The constituents of waterpepper to evoke elaxation of duodenal smooth muscle were stable to heat. The cows administered waterpepper showed common clinical symptoms such as acrid expression, restlessness, dullness, inappetence, anorexia, severe diarrhea, mild bloat and left displacement of abomasum, while bloody feces was shown in a cow. The goats administered the mothanol extract showed common clinical signs such as acrid expression, restlessness, dullness, inappetence and soft feces, while bloody feces was shown in a goat, A goat adminstered the crude juice showde bloody feces and diarrhea. Respiratory rates and heart beats were increased along with diarrhea in the experimental cows. The erythrocyte counts and MCHC were decreased whereas PCV, MCV and neutrophils were increased in the cows administered waterpepper. In goats administered methanol extract, there were decreases in erythrocytes, PCV and hemoglobin content, and an increase in MCHC. The goats ingester with the crude juice showed negligible changes in hematologic values compared with control group which was administered the same amount of water instead of the crude juice. The contents of serum calcium, Inorganic phosphorus, magnesium, Iron, glucose, cholesterol, total protein, triglycerides and phospholipids were tended to decrease in cows. In goats serum iron, glucose, triglycerides, cholesterol, BUN and phospholipids content were decreased while the content of sodium and chloride were increased after administration of the methamol extract The goats ingested with the crude juice did not show significant changes in serum chemical analysis. Even though there were some pathological findings such as hyperemia in the small intestines and kidneys and swelling of liver parenchymal cells, the values of serum AST, ALT, LDH, alkaline phosphatase, total bilirubin and creatinine did not change significantly. While proteins, hemoglobin and blood were detected in the urine of cows, urine pH, ketone bodies, glucose, bilirubin and urobilinogen content were normal or undetected. There were no significant changes in pH/bolld gas analysis data of cows and cholinesterase activities of plasma and erythrocytes of cows and goats ingested with waterpepper or the methanol extract. It is concluded that waterpepper irritates the gatrointestinal system, causes abdominal pain, relaxes the gastrointestinal smooth muscle and dilatates blood vessels supplied to the system. The irritation and relaxation may lead to abnormal fermentation, maldigestion and malabsorption of nutrients and result in diarrhea, body feces, mild bloat and left displacement of abomasum.
