In this paper we have proposed a method for solving a four-coloring problem using adjusted information transmission between adjacent neurons in neural networks. These algorithms are based on McCclloch-Pitts binary neuron model neural networks. If a map shares n regions, a 4×n neural array is used to color a map of n regions where each neuron as a processing element performs it. By programming these algorithm by a C-language in IBM PC 486 DX and adapting it to various examples, we have showed the ability of our system. If one neuron is selected among four neurons, the strength of order three neurons is wakened. So, by transmitting the information of selected neuron, adjacent neurons cannot share the same color.

Streptococcus faecalis는 glucose, lactose등을 탄소원으로 잘 이용하였으며 glucose를 탄소원으로, yeast extract와 casitone을 질소원으로 구성된 배지를 사용하여 pH 7.0에서 control되는 fermentor 배양에서 optical density(660nm) 7.3(viable cell concentration 6.5×10(9) cells/㎖)이상의 높은 cell concentration을 얻을 수 있었다. Bacillus mesentericus의 sporulation을 최대화 하기 위한 발효 조건을 조사한 결과 glucose를 위한 최적 CaCl₂농도는 0.lmM이었다. Streptococcus faecalis rapidly fermented glucose and lactose as a C-source, and the maximum cell concentration was obtained when grown in a jar fermentor that contained YCG medium consisting of glucose as a C-source and casitone and yeast extracts as a N-source, and that was controlled at pH 7.0. From experiments to maximize the sporulation efficiency in Bacillus mesentericus, glucose caused the decrease in sporulation efficiency, and calcium chloride was stimulatory for sporulation, of which optimum concentration was 0.lmM.

Background: To manage the EMS(emergency medical services) system effectively, departments, such as fire stations, emergency information centers, hospitals, and The Ministry of Health and Welfare, should exchange information that they own and/or gather during patient care and/or transportation. Medical records and information are very important for continuing the patient's care and for deciding on a treatment plan, but medical information is not exchanged fully in spite of its importance. Method: We analyzed the transfer medical reports that were written by medical doctors who transferred emergency patients to our hospital. The contents and the accuracy of the transfer medical records were analyzed and graded into 4 groups. Group A was fully described and was equipped with diagnosis, laboratory data, X-ray fi1ms; group B had a diagnosis and full laboratory data; group C had a diagnosis, but only partial laboratory data; and group D had only a diagnosis. Results: Among 38,214 patients who visited our hospital from Jan. 2001 to Jun. 2001, 7,031 cases were transferred from other hospitals with transfer medical records. According to the accuracy and important contents of the transfer records, Group A occupied 1.9%, group B 5.2%, group C 32.5%, and group D, with only a diagnosis,60.4%. In the case of our hospital, we delivered all emergency medical information by written paper(transfer note), E-mail, and web-based information system(caber-AMC) to the doctors concerned with managing the patient. However, 93% of the medical records of patients transferred from other hospital contained insufficient information to adequately care for the emergency patients. In addition, most of the transferred patients had been transorted without prior information about transportation. Conclusion: Within the near future, a medical information center equipped with a computerized system should be operated to exchange medical data. As most general hospitals are operating the OCS(order communication system), EMR(electronic medical record), telemedicine, and PACS(picture-archiving communication system), medical information can be exchanged freely in real time if a code standard and HL7(Health Level 7) can be established.

There has been a little hiistopathologic study concerning the bony healing of injured labyrinth. Authors obserbed a seriease of morphologic change of guinea pig temporal bone after transection of the lateral semicircular canal(LSCC). In the 1st. postoperative week there was a proliferation of perilymphatic connective tissue meshwork along with aggregation of fibroblast around the necrotic material occluding transected bony canal lumen. In the 2nd, postoperative week there was a fibroblastic ingrowth with callous bone formation over the surgical defect of LSCC. In the 4th. postoperative week the fibrous tissue over the surgical defect completed callus formation, and the necrotic material in the canal lumen showed on going new bone formation. These findings suggested that the periosteal layer conduct early calus formation, and the endosteal layer paly a role in forming enchondral bone in late stage.

The purpose of this study is to observe the stimulant effect of the isolated nerve segment on the peripheral nerve regeneration using silicone tube in rats. Srague-Dawley female albino rats were used as experimental animals and nerve defects were made by resection of 14 mm-long segment of right sciatic nerves. In control group, the defects were bridged with the silicone tubes. In experimental group, the defects were bridged with the same manner and additionally, 2mm-long nerve segments were inserted at the center of the silicone tubes. 3 months later, the regenerated nerve tissue within the silicone tubes were examined by histologic study. Axonal diameters and numbers of axons were measured and all data were analyzed by using SAS package program. The results obtained were as follows : 1. The experimental group was increased than the control group in general diameters of the regenerated nerve fiber.(P<0.05) 2. The diameters of axons were increased int he experimental group compare to the control group. (P<0.05) 3. The numbers of axons were increased int he experimental group compare to the control group. (P<0.05)

<黃帝內經>에 流入된 五行學說에 關한 硏究

金富煥,朴炫局 동국대학교 한의학연구소 1992 東國韓醫學硏究所論文集 Vol.1 No.-

The purpose of this study is how to have the form and theory of the five element theory in the 〈whang di nei ging〉〈黃帝內經〉by the investigation of the course of the five element introduced the ancient oriental medicine from ancient oriental philomphy. The following results were obtained. 1. The five elements in 〈Sang Seo〉(尙書) meaned the five uses of water, fire, earth, wood, metal which were insportant in living. Because these had very important meaning in ancient political and economic society, emphasized to big law(洪範) 2. The five elements in 〈zya zyern) (左傳) and 〈kuk oe〉(國語) means the five uses too, and here are the phrases of "fire win metal"(火勝金) and "water win fire"(水勝火), but these only meaned the physical interrelation. 3. In the five circulating factor theory made by Chu Yen(鄒衍) which have the attribute of the five elements, he more reasonably had argued human affairs like that a dynasty become different in step with the circulating five favors. There is the regular annual policy in the (Ye Si Gun Cu) (呂氏春秋) which closely connected nature and human living, and attached the various colors, animals, visceras, flavors, sounds, the sexagenary cycle and so on to the five elements. 4. In the <Cun Cu Bun Ro>(春秋繁露) writed in the fore-period of Han(漢) dynasty, the interactions of the five elements are concretely applicated to policy, Dong Jung Soe(董仲舒) had discrived the interactions of the five elements by the Dong Lyu Sang Dong thery(同類相動說) and the misfortune theory(災異說), emphasized the sympathy of nature and human. Though there is many contents which are superstitious and contradictory, I concider which that affcted many effects in the formation of five element theory of oriental medicine. In the <Hye Nam Ja>(淮南子) the order of matters were explained by the five element theory too, as the interrelations of the five elements were explained by the sexagenary cycle, I assume that the bud of O-Un theory(五運理論). And there was not founded the fullscale intriduction of the five element theory in the Ma Wang Tye(馬王堆) excavated finds, the Mu Yyi medical writings formed the Han dynasty(武威漢代醫簡) and the documents about Pyun Jak(扁鵲) and Sun U Ie(淳于意). 5. The application of the five element theory in the <Whang Di Nei Qing> (黃帝內經) is devided into the attachment to the fire elements, the interelations of the five elements, and Un Gi theory(運氣論). In the attachment to the five elemeant theory, it made the attachment of the five visceras of <Kum Mun Sang Seo>(今文尙書) party a standard and attached the sections of a human body, the whole internal organs, the five organs of sense, the five colors, the five flavors and the five sounds and so on to the five elements. It put to use by means of the application of the interrelation of the five elements in the transferations of the diseases and the relative severeness of a disease in step with the change of time and season. Un Gi theory(運氣論) which synthesized by the attachment to the five elements, the inter-relations of the five elements and the: climate which observerd from ancient times systematically argued the effects of weather to human. 6. The application of the five element theory in the <Whang Di Nei Qing>(黃帝內經) have the significant what had get rid of the irrational factors like that the emotion and action of human could to influense the weather, what had been formes more rational thinking by the observation of human and nature. It is required more reserches about the possibility of the formation of the doctrinal faction by the geographical effect of the Yon, Je(燕, 薺) region, the application of the five element theory in other ancient medical books and the relationship of the five element theory and Yin Yang(陰陽)

Sudden hearing loss is an abrupt onset of sensorineural hearing loss over a period of hours or a few days without definite cause. The cause and its pathophysiology have not been fully determined, and the treatmnet is controversial at present. The purpose of this study is to seek the best modality of treatment by clinical and stastical analysis of 48 patients (28 male and 20 female) diagnosed as a sudden hearing loss from January 1993 to October 1995. The therapeutic results of the 48 patients were 20 cases (41.7%) of complete recovery, 3 cases (6.2%) of partial recovery, 4 cases (8.3%) of slight recovery and 21 cases (43.8%) of no improvement. Early treatment within a week of onset, ascending or flat types of audiogram, and normal ABR were favorable prognostic factors in recovery of hearing. The presence of accompanying vestibular symptom (ie, vertigo) and profound hearing loss on initial audiogram were poor prognostic factors. However, the gender and the age of the patients did not affect on the hearing result.
