Parallel combination, little significance is given on performance of Recognizer but its performance depends on how to combine. In the serial combination, the results of the Recognizer are ignored and different results can be produced. And, performance even after combination is not much improved compared with that of a single Recognizer. Therefore, this study aims to make up for methods of combination of multi recognizer shortcomings menthioned above. That is, we use an advantage of parallel Recognizers, using two or more resultant values, and those of Recognizers of the serial combination, considering supplements of recognizers and a point of several steps of verification. Therefore, this study tend to suggest the results of research and experiments on methods of recognize the combination of the results from three nodes of recognizers which in parallel are linked in the form of total three pipeline.

박범룡,류영호,조동환,김정기 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.3

연구목적: 이 연구는 청소년의 가족 폭행에 대하여 조사하고 가족폭행의 관점에서 불량행위 청소년의 특성을 규명하고자 하였다. 방 법: 저자들은 불량행위 청소년 238명, 범죄 청소년 209명, 그리고 부산시대 고등학교 학생 230명을 대상으로 설문지, 다면적 인성 검사(Minnesota Multiphasic Personality Inventory), 그리고 한국판 부모-자녀 결합도 검사(Parental Bonding Instrument0 등의 도구를 사용하여 조사하였고, 그것으로 세집단을 Chi-square test, T-test, 그리고 ANOVA를 사용하여 비교 분석하였다. 결 과: 대개의 경우 불량행위 청소년의 사회경제적인 상태가 학생군보다 더 불량하였고, 범죄군보다는 더 양호하였다.(p<.05) 일반적으로 폭행가해자들은 손위형제였고, 신체적으로도 피해자보다 더 강했고, 형제간의 우애는 좋지 않았다. 학생군과 비교할 때 존속에 대한 폭행을 포함한 폭행의 심각성은 불량행위 청소년과 범죄 청소년에서 존재하고 있었다. 다면적 인성검사와 부모-자녀 결합도 검사의 결과, 가족폭행군과 비폭행군을 비교할 때, 불량행위 청소년군의 경우에는 Sc척도와 Passive aggresive index에서 학생군의 경우에는 아버지 과보호에서 의미있는 차이를 보였지만 그외의 척도에서는 의미있는 차이를 찾을 수가 없었다. 결 론: 일반적으로 가족폭행의 특성으로도 기존의 사회 정신의학적 고찰의 결과와 같이 불량행위 청소년군이 학생군과 범죄청소년군의 중간특성을 가지고 있는 것으로 나타났으며 가족 폭행 문제의 심화를 막기 위하여 이 집단에 대한 적절한 개입이 필요할 것으로 생각되어진다. Objectives : This research was performed to identify family violence by male adolescents, and to examine the characteristics of male adolescent delinquents in terms of domestic violence. Methods : We surveyed 677 male adolescents including 238 delinquents from BBS(Big brothers and sisters) in Pusan, 209 criminal adolescents from adolescent correctional institution in Pusan, 230 high school students through questionnaire, MMPI(Minnesota Multiphasic Personality Inventory), and PBI(Parental Bonding Instrument), and then compared these three groups by Chi-square test, T-test, and Anova. Results : In most cases, male delinquent adolescents were placed in poorer socio-economic conditions than those of students, but in better socio-economic conditions than those of criminal adolescents. In general, the assaulters were senior family members, physically stronger than sufferers, and have bad brotherliness. Compared with normal students, the serious problem of violence including violence to the ancestors in delinquent and criminal adolescents. On results of MMPI and PBI test, there were significant difference between violent group and non-violent group on the Sc score and Passive aggressive index in adolescent delinquents and parental overprotection in normal students. Conclusion : Generally the characteristics of family violence by male delinquent adolescents were intermediate between those of criminal adolescent and students, these results were same as those of previous socio-psychiatric study, and so the intervention in criminal adolescents is needed for the prevention of family violence.

Kohonen의 자율 학습 신경망칩을 위한 OTA 곱셈기와 수정된 Gilbert 곱셈기의 비교

이상범,조용범 건국대학교 1995 學術誌 Vol.39 No.2

This paper compares characteristics of OTA multiplier and the modified Gilbert multiplier for neural chips of Kohonen's SOM algorithm. To design neural chip, it is necessary to reduce the size of circuits because a massive number of imterconnectlons between neurons are used. For the comparision, the performance of two multipliers was tested by SPICE circuit simulations. OTA multiplier has approximately a half size of the modified Gilbert multiplier. OTA multiplier also has wider operation range from -4.8V to 4.8V compared with the modified Gilbert multiplier ranging from -0.5V to 0.5V. Test spice cells for OTA multiplier-based neural processor and the modified Gilbert multiplier-based neural processor were also desgined and tested for comparisons. The entire operation speed of test slice cells was that OTA multiplier - based neural processor had 27ns rising time and 55ns failing time, and the modified Gilbert multiplier-based neural processor had 53ns rising time and 60ns falling time. The proposed OTA multiplier can be used for highspeed and high integrated applications.

Lutembacher's syndrome is rare combination of mitral stenosis (MS) and atrial septal defect (ASD). The hemodynamic interplay between the MS and ASD leads to wide variation of clinical presentation. Here we describe a 43-year-old female with Lutembacher's syndrome and tricuspid regurgitation with pulmonary hypertension, who underwent direct closure of ASD and tricuspid valvuloplasty successfully. We also reviewed other literatures in an effort to increase awareness of this condition.

Chitosan 濾過 System을 利用한 새로운 中水道 工程의 開發과 溫泉水 淨化에 관한 硏究

김용범,백광욱,안병제,조영주,심재용 서울産業大學校 1994 논문집 Vol.39 No.1

각종 금속이나 중금속을 비롯하여 각종 오염물(SS, COD, BOD, CI 등)을 강력히 흡착제거하는 성능을 가진 chitosan(Cs)응집제와 여과사(SF) 및 활성탄 column(ACC)을 병용하여 hotel잡수와 온천사용수등의 정화실험을 행하여 생물학적 처리과정을 생략할 수 있는 사용수의 재활용 process(Fig. 1)를 개발하였다. 이 process에서 hotel 잡수의 경우 20ppm의 chitosan 투입으로 1차응집 처리하여 약 60%이상의 오염물을 제거한 후 여과사와 활성탄 column을 이용하여 최종적으로는 80~99%의 오염물을 제거할 수 있었다. 또한 온천수의 경우 20ppm의 chitosan 투입으로 1차응집 처리하여 약 50%이상의 COD와 BOD의 제거율을 달성할 수 있었다. 따라서 이러한 process를 산업현장에 적용할 경우 종전의 생물학적 공정을 생략하거나 소규모화하여 보다 간편하며 처리공간이나 경비등을 절감하면서도 사용수를 방류수 또는 재활용수 기준이내로 처리할 수 있음을 확인하였다. 본 연구는 수자원 보호나 수자원 재활용면에서 크게 기여 되리라 믿는다. A simplifid and economic process for recycling the used water discharged from a large scale residence(e. g. hotel and apartment etc.) was developed. The used water was purified through adsorption and flocculation of contaminants by chitosan at the first stage where the average removal rates of COD and BOD of the used water were found more than 60%. The previously treated water through flocculation by chitosan was subjected to filtration systems of a sand filter and an activated carbon column, and the average removal rates of COD and BOD were found more than 80%. The experimental results suggest that the biological process which is very popular in the treatment of the used water for the removal of COD and BOD can be omitted and expected to reduce a spacial and running expenditure. On the other hand, testing the used water discharged from hot springs with chitosan proves a possibility of development of a simple and economical process for the treatment of the used water to the criteria of recycled water quality without any addition of more complicated equipments and facilities.

Surgical Treatment of Subdural Hygromas in Infants and Children

Cho, Jun-Beom,Cho, Ki-Hong,Kim, Se-Hyuk,Shin, Yong-Sam,Lee, Won-Chung,Yoon, Soo-Han The Korean Neurosurgical Society 2005 Journal of Korean neurosurgical society Vol.38 No.4

Objective : There is no acceptable indication and treatment of choice for infantile and child subdural hygroma and there are only a few reports about that in Korea. So the authors studied the clinical findings of infantile and child patients with subdural hygroma to improve the understanding and to suggest a standard treatment method. Methods : The authors retrospectively evaluated the causes, preoperative symptoms, radiological thicknesses, and postoperative results of 25patients with subdural hygroma who received surgical therapy. Results : There were 16boys and 9girls whose median age was 6months[range $2{\sim}120months$]. The main clinical manifestations were seizures, increased intracranial pressure, macrocrania and alteration of consciousness. Radiological thicknesses of the subdural hygroma varied from 7mm to 42mm and postoperative changes of thickness[y] could be expressed with the factor of month[x]: $y\;=\;-1.32\;{\times}\;+11.8$ in subdural drainage, and $y\;=\;-1.52\;{\times}\;+14.9$ in subduroperitoneal shunts. Of the 25patients, 2 [50%] were successfully treated by aspiration, 13 [59%] by subdural drainage, and 9 [69%] by subduroperitoneal shunt. Conclusion : It is suggested that the diagnosis and treatment of subdural hygroma in infants and children should be carefully addressed because of its high prevalence in children, and especially in infants. It is also suggested that the subdural drainage could be primary initial treatment method because it is simpler than a shunt, and since our data show that there is no statistical difference in postoperative recovery duration between the two operative methods.
