        이한웅,최면송,이승재,강상희 明知大學校 産業技術硏究所 2003 産業技術硏究所論文集 Vol.22 No.-

        Abstract - This paper presents a fault location algorithm when there are parallel circuits in power system networks. In transmission networks, a fault location method using the distribution factor of fault currents is introduced and in distribution networks a method using direct 3-phase circuit analysis is developed, because the distribution networks are unbalanced. The effect of parallel circuits in fault location is studied in this paper. The effect is important for the range of protecting zones of distance relay in transmission networks and fault location in distribution networks. The result of developed fault location algorithm shows high accuracy in the simulation that using the EMTP.

      • β-Carotene과 알코올을 섭취한 쥐의 혈액 성분변화의 상관관계

        고재웅,조만희,이상한,우기민,염윤기,김창세 순천향의학연구소 2000 Journal of Soonchunhyang Medical Science Vol.6 No.2

        The study was carried out to investigate the effects of dietary carotenids and β-carotene on the hematological changes caused by alcohol administration into the rats. The results were analyzed using several statistical methods; SPSS computer program for measuring the mean values and standard deviations, one way ANOVA for the test of significance, Duncan method for post HOC multiple comparison, and Pearson method for measuring the correlation coefficient. The following are the conclusion from those statistical analysis. 1. ALB and TB were shown to have the most significant correlation among the blood compositions f개m the basic dietary groups. 2. BUN and CHO were shown to have the most positive correlation among those from the carrot-fed groups. 3. CA and AG were shown positively correlated, and CHO and IP negatively correlated, respectively among those from the cheese-fed groups. 4. AP was shown positively correlated among those from the alcohol-administrated groups. 5. CHO, CA and BUN were shown positively correlated, and CA was negatively correlated among those from the β-Carotene -fed groups. 6. TB and TP were not affected by the correlations between the blood composition from all the experimental groups.

      • 대퇴골두 무혈성 괴사에 속발된 대퇴경부 골절

        임수재,제한웅 순천향의학연구소 2005 Journal of Soonchunhyang Medical Science Vol.11 No.1

        Purpose : This paper studies characteristics, occurrence types, radiographs, MRI(magnetic resonance imaging), and histopathologic findings of femur neck fracture following avascular necrosis of the femoral head. Materials and Methods : The subjects of this study are femur neck fracture following avascular necrosis of the femoral head occurring in 7 cases of 7 Patients with osteonecrosis of femoral head among 130 cases of 68 patients who were treated at our hospital from March 2001 to March 2005, and analyzed though plain radiography finding, MRI, and histopathologic test. Results : All 7 cases were found of osteonecrosis of the bilateral femoral head, and most of avascular necrosis in parts of femoral neck fracture had invaded entire femoral head. Simple radiographic findings were 1 case of stage Ⅱ, 4 case of stage Ⅲ, and 2 cases of stage Ⅳ according to the Ficat and Alert classifications, MRI finding included 5 cases of class C, 2 cases of class D according to the Mitchell classification, and all cases found lesions of low signal intensity in T1W1, high signal intensity in T2W2, and other parts. The 1 case of histopathologic test developed femur neck fracture between the necrotic zone and the reparative zone. The form of femoral head fracture includes 5 case of type A, and 2 case of type B according to the Usui classification Conclusion : A spontaneous femur neck fracture can occur without any special exterior force between the necrotic zone and reparative zone in case invaded with wide range of osteonecrosis of the femoral head.

      • 실용적 LTJ 적응필터에 관한 연구

        유재하,김한웅 안성산업대학교 2002 論文集 Vol.34 No.-

        In this paper, calculation method for the components of transformation matrix J(n) and K(n) in the LTJ(Lattice Transversal Joint) adaptive filter was explained in detail. And it is shown that the LTJ adaptive filter can be used practically in applications of digital speech communication such as hands-free communication. In case of G.723.1 speech CODEC, additional complexity over transversal filter is only 15%.

      • 獨逸民法 제618조의 制定에 관한 硏究

        柳在南,韓雄吉 東亞大學校 1990 東亞論叢 Vol.27 No.1

        Zur Festectzugn des Burgerliches Gesetzbuch im Deutschland hat der Art, 120 der Gewerbeordnung fBur das Deutsche Reich in der fassung vom 26. Juli 1990 als des Grund der Entschadigung fu den Arbeitsunfall eine groβe Rolle gespienlt. Es war aber fur den zunehmende Arbeitsunfall nicht genugend entschadigt geworden. Im jahr 1888 wurde dann das Burgerliches Gesetzbuch von Deutschland offentlich bekannt gemacht. Doch war die Festsetung zur Fursorgepflicht wriklich inder acht Texte zum Dienstvertrag gar nicht ausdrucklich erwahnt. Deshalb hat der Art. 617 und 618 in der Wirking von Otto Friedrich von Gierke und Anton Menger Feststellt werden, so haben die ganzen Entschadigungen verwirklicht werden. In dieser Arbeit wird dieser Feststellungsverlafu unter den damalige gesellschaftliche hintergrund und die Gesetzgebungsmate realen in folgender Reihenfolge geschrieben. Ⅱ. Die Stellung zum Arbeitsunfall vor der Gesetzgebung des Burgerlichen Gesetzbuch Ⅲ. Der Feststellungsvorgang der Fursorgepflicht und der historische hintergrund im Burgerlichen Gesetzbuch Ⅳ. Die Interpretation des Art. 618 vom burgerlichen Gesetzbuch Ⅴ. Schluβ Es gibt aber noch viele kommentierende Probleme, dazu wird es beider nuchsten Gelegenheit weiter untersucht werden.

      • 附子 및 硫璜의 複合製劑가 家兎血中 酒精濃度에 미치는 實驗的 硏究

        洪載奉,李雄烈,朴宗漢,李時炯 최신의학사 1974 最新醫學 Vol.17 No.8

        We had found Gollin, a compound of aconite and sulfur, was quite effective in controlling hangover syndrome in the previous clinical study. In this study, we have tried to explain the possible biological mechanism of its effectiveness, at least in part, by way of analyzing blood alcohol clearence rate. Nature rabbits of both sexes, weighing between 2.0 kg and 3.0 kg were used. Experimental group was given five capsules of Gollin in liquid form 20 minutes prior to L V. injection of 50 Vol. % of ethanol in a dose of 5.0 ml/kg of body weight. All of the specimens. were obtained by cardiac pucture at 10 and 30 min. respectively after alcohol edmini?stration. The result showed blood alcohol clearence was much enhanced in the experimental group and it was more so at 10 min. than 30. A possible mechani?sm for this finding. was discussed and this result was also related to the clinical effectiveness of Gollin in controlling hangover syndrome.

      • 산업대학 건축공학과 교육과정 개발에 관한 연구

        임응찬,한인웅,이승준,박재호,조방현,서형수,정구용,한기원,김진원,임상규,이재윤 三陟大學校 1996 論文集 Vol.29 No.2

        By impproving the educational program of the Department of Architectural Engineering and studying the theory of learning and the applied method necessary for the development of nation and society, we should develop a satisfying course of education to meet the demand and skill in the industralized society for the purpose of cultivating men of baility with great personalities and creative minds. Therefore, this study focused on classifying several kinds of occupations in the prart of architectured related to what graduates from the department of Architectural Engineering go with into the society. Accordingly after choosing some works adequate to each occupation by the proposed curricula, we tried to establish the scope of education and courses corresponding to the jobs and thus and develop a satisfying curriculum.
