This paper proposes a time series prediction method for the nonlinear system using the fuzzy system and the evolutionay strategy and the genetic algorithm. At first, we obtain the optimal fuzzy membership function using the evolutionary strategy or genetic algorithm. With the optimal fuzzy rules and its input differences, a better time prediction series system may be obtained. We obtain a good result for the time prediction of the regional electric load. In addition we implement the graphic user interface for the proposed algorithms.

연구목적 : 이 연구는 불량행위 청소년군과 학생군을 대상으로 학교내외에서 행하는 폭력행동의 특징을 알아보고 특히 가해자의 정신병리와 청소년의 폭력행동과의 관계를 알아봄으로써 학교폭력의 이해와 대처방법 그리고 예방프로그램의 수립에 도움이 되고자 한다. 방 법 : 불량행위 청소년(청소년 선도프로그램인 BBS참석자) 남자 331명과 남자 중고등학교생 394명을 폭력의 유형을 괴롭힘, 금품갈취, 신체적 폭력, 언어적 폭력, 위협 등의 5가지 유형으로 나눈 설문문항을 바탕으로 각 경우의 경험빈도를 5점 척도로 하여 각 문항에서 3점 이상을 가해자군으로 분류하였으며 설문지를 통한 조사와 정신병리의 측정도구로서 한국판 아동-청소년 문제행동 평가 척도표(CBCL : Child Behavior Checklist, 청소년용)및 청소년의 자기개념을 알아보기 위해 한국판 피어스-해리스 소아 자기 개념척도(Piers-Harris Children's Self-Concept Scale, Piers, 1984, 이하 자기개념척도)를 적용하였으며 Chi-square test, T-test, 그리고 Two-way ANOVA를 사용하여 비교하였다. 결 과 : 사회 인구학적 특성에서는 대부분의 요인에서 불량행위군과 학생군 그리고 가해자군과 비가해군간에 차이는 보이지 않았으나 흡연과 음주하는 비율이 불량행위군과 학생군 두 군 모두 가해자군이 비가해자군보다 의미있게 높게 나타났다. 부모의 부부싸움 빈도는 불량행위군에서는 가해자와 비가해자군간에 차이를 보이지 않았으나 학생군에서는 가해자군에서 종종 싸운다는 비율이 의미있게 높게 나타났다. 학교생활에서는 성적이나 교우관계에서는 두 군 사이와 가해여부에 따라 유의한 차이를 보이지는 않았으며 성적은 불량행위군이 학생군에 비해 낮은 반면 가해여부에 따라서는 차이가 없었다. 하지만 학생군에서는 가해자군이 비가해자군보다 성적이 낮았으며 만화방을 이용하는 빈도도 가해자군에서 높게 나타났다. 폭력물 시청 시 느낌은 불량행위군과 학생군 모두에게서 가해자군이 비가해자군에 비해 흥분된다는 비율이 높게 나타났다. CBCL(Child Behavior Checklist)척도는 불량행위군의 경우 비행, 공격성, 외현화, 사회성 척도가 학생군에 비해 유의하게 높았고 위축, 사회적 미성숙, 사고문제, 주의집중, 내재화 척도는 학생군에서 불량행위군에 비해 유의하게 높았다. 전체 대상군을 가해자군과 비가해자군으로 나누어 비교하였을 때 신체증상, 사고문제, 주의집중, 비행, 공격성, 내재화, 외현화척도에서 가해자군이 비가해자군에 비해 유의하게 높았으며 군과 가해여부의 상호작용효과 검증결과에서는 유의한 상호작용을 보이는 척도는 없었으나 각 집단의 모든 척도에서 가해자군이 비가해자군보다 높은 점수를 보여주었으며 불량행위군의 경우 가해자군일수록 비행, 공격성, 외현화 척도가 높아지는 경향을 보였으며 학생군의 경우에서도 마찬가지로 비행, 공격성, 외현화 척도에서 가해자군이 비가해자군보다 높게 나타났다. 자기개념 척도는 불량행위군의 경우 행동, 지적학업척도에서 학생군에 비해 유의하게 낮게 나타났으며 불안, 인기척도는 학생군에서 불량행위군보다 유의하게 낮게 나타났다. 전체 대상군을 가해자군과 비가해자군으로 나누어 비교하였을 때 행동, 지적학업척도는 가해자군이 비가해자군에 비해 유의하게 낮은 점수를 보여주었으며 각 군과 가해여부의 상호작용검증결과에서는 유의한 상호작용효과를 보인 것은 없었으나 두 군 모두 행동척도가 가해자군이 비가해자군에 비해 낮은 경향을 보여주었다. 결 론 : 불량행위군과 학생군에서의 폭력가해자는 사회인구학적 변인에서는 비가해자와 유사한 특징을 가지나 각자의 내재된 심리상태와 정신병리에 따라 폭력 영상물과 음주 흡연의 가능성증가 그리고 가정에서의 폭력의 학습 등 주변의 위해 요인에 가해자군이 비가해자군에 비해 영향을 많이 받는 것으로 생각된다. 이에 학교폭력에 대한 대책수립 시 결과에만 초점을 맞춘 처벌 위주의 방식에서 벗어나 이들이 가진 심리적 특징과 정신병리를 이해하고 그에 따른 예방적인 대책수립이 필요할 것으로 생각된다. Objective : The purpose of this study was to identify the characteristics of school violence, self concept, psychopathology and psychosocial characteristics of male aldolescent delinquency doing school violence. And we hoped to use this result as basic material for prevention of school violence through comparison of those of students group. Method : We surveyed 725 male adolescents including 331 deliquents from educational program called "Big Brothers and Sister" in Pusan. We used self-reporting questionnaire composed of demographic data and attitude to violence. In order to investigate the psychopathology and self-concept, we used Child Behavior Check List, Youth edit, Korean version(CBCL) and the Piers-Harris Children's Self-Concept Scale. Statistical methods employed were Chi-square, t-test, two-way ANOVA. Result : The results show that in most demographic and psychosocial factor including age, education, socio-economic condition, religion and relationship with friends, there was no significant difference between delinquent and student group. And there was no significant difference between bully and non-bully in both group. The frequency of alcohol drinking and smoking were higher in bullying groups. For the feeling of watching violent mass-media, bullying delinquents reported more excited state than non-bullying delinquents in both group. On results of CBCL, subscales of delinquent behavior, aggressive behavior, externalizing problem, social scale in delinquent group were higher than those in student group. Subscale of somatic complaints, thought problem, attention problem, delinquent behavior, aggressive behavior, internalizing problem, and externalizing problem in bullying group were higher than those in nonbullying group. In both delinquent and student group, subscale of delinquent behavior, aggressive behavior, and externalizing problem in bullying group were significantly higher than those in nonbully group. In the results of self-concept scale, subscales of behavior, intellectual and school status in delinquent group were lower than those in student group. Subscale of somatic complaints, thought problem, attention problem, delinquent behavior, aggressive behavior, internalizing problem, and externalizing problem in bullying group were higher than those in nonbully group Conclusion : In both delinquent and student groups, most psychosocial factors in bully group were not significantly different with those in nonbully group. Bully group was more influenced by internal psychic state, psychopathology and environmental factor than nonbully group.

The purpose of this study was to make ramyon from Korean cultured wheat by adding with hot water extract powder from safflower seed in order to add the value of it. The cooking quality, instrumental texture and sensory characteristics of ramyon were analyzed. The ramyons with 0.1%, 0.3%, 0.5%, and 0.7% of hot water extract powder(HEP) from safflower seed, control, and those with 3% and 5% of dried powder(DP) from safflower seed were compared. The yield of HEP was 7.8%. Lightness, redness, Max. weight, strength, hardness, adhesiveness, cohesiveness and springiness were measured. As the amounts of HEP and DP was increasing, ramyons smelled stronger and was getting harder and chewier, while became less transparent and had no difference in elasticity and adhesiveness. In overall acceptability, both control and ramyon with HEP had similar points. From three important factors, appearance, color and smell to make ramyon more acceptable, addition of 0.3~0.5% of hot water extract powder from safflower seed was found to be the best. However, further studies on smells are needed to make processed foodstuffs with safflower seed.

만성 C형 간염 환자에서 페그인터페론 알파2a와 리바비린 병합 치료중 발생한 벨마비 1예

김일환,장제혁,유충헌,최규남,고정해,김윤정,서광원,김지현,박성재,박은택,이연재,이상혁,설상영 인제대학교 2008 仁濟醫學 Vol.29 No.-

페그인터페론과 리바비린 병합요법은 만성 C형 간염의 일차 치료법이다. 저자들은 만성 C형 간염 환자에서 페그인터페론 과 리바비린 병합 요법 중에 발생한 벨마비 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. 환자는 5년 전부터 만성 C형 간염을 앓아온 48세 남자이며, PEG-IFN α-2a 135μgm 피하주사 주1회와 하루 1200㎎의 리바비린을 투여하였다. 치료시작 후 9개월째 환자는 오른쪽 안면의 근력약화를 호소하였으며 벨마비로 진단되었다. 페그인터페론과 리바비린 병합요법을 지속하면서 관찰하였다. 환자의 벨마비는 페그인터페론 치료를 중단하지 않았음에도 3개월후 증상이 회복되고 이후 벨마비 재발 없이 현재 경과관찰 중이다. 만성 C형 간염에서 페그인터페론과 리바비린 병합 요법시 벨마비의 발생 가능성을 염두에 두어야 하겠다. A Case of Bell's Palsy Associated with Combination Therapy of Pegylated Interferon Alfa-2a (PEG-IFN) and Ribavirin for Chronic Hepatitis C Virus Infection Pegylated interferon alfa(PEG-IFN α) and ribavirin therapy is the first line treatment for chronic hepatitis C. Mild complications of the therapy are common, but more serious complications are rare. We report here a case of Bell's palsy that occurred in a patient with chronic hepatitis C virus infection during combination therapy of PEG-IFN α-2a and ribavirin. The patient was 49-year-old man with chronic hepatitis C (genotype 1b) for 8 years. He had compensated liver cirrhosis with splenomegaly. Therapy with PEG-IFN α- 2a 135mcg/week and ribavirin 1200mg/day was initiated. After 9 months of the therapy, the patient showed a loss of muscular tone on the right side of his face. A diagnosis of Bell's palsy was made. The Bell's palsy resolved over 3 months despite continuation of the combination therapy.

Background and Objectives : Several speech manifestation are observed in temporal lobe epilepsy(TLE). We studied the frequency of ictal speech manifestations and their localizing and lateralizing value in TLE. Methods : We reviewed 379 seizures recorded on videotape in 135 patients who underwent temporal lobectomy for intractable TLE. We divided patients into group A(n=75) who became seizures free after surgery, and group B(n=60) who were only slightly benefited or unchanged after surgery. Speech manifestations were classified as normal speech, vocalization, or abnormal speech. Abnormal speech was subdivided into speech arrest, dysarthria, dysphasia, or nonidentifiable speech. Results : Speech manifestations occurred in 70(18.5%) seizures of 28 patients. Forty eight seizures of 20 patients were observed in group A, and 22 seizures of 8 patients were observed in group B. In group A, 25 seizures of 11 patients were originating from dominant hemisphere, 23 seizures of 9 patients from nondominant hemisphere. In group B, 13 seizures of 5 patients were originating from dominant hemisphere, and 9 seizures in Lt. side and 6 seizures in Rt. side, respectively) of group A(P>0.05), and eleven seizures of 4 patients(8 seizures from Lt. side and 3 seizure from Rt. side) in group B(P>0.05). Normal speech was observed only seizures from Rt. side in both groups(3 seizures in 1 patient, each group). Dysphasia occurred only in seizures originating from Lt. side. Nonidentifiable speech occurred in 22 seizures of 9 patients(11 seizures from each side) in group A(P<0.01), and 3 seizures of 1 patient occurred only from Lt. side in group B. Conclusion : Ictal speech manifestations were not uncommon(18.5%). All kinds of ictal speech manifestations except normal speech have no reliable lateralizing and localizing value in TLE. Normal speech could be a good indicator of seizure originating from nondominant hemisphere.

This Study has examined the influences of the images of the pro soccer teams on the images of the businesses by the method of covariance structure analysis. That is, the structural model of the influences of the images of the pro soccer teams and then the causal relationship of each variable has been analyzed quantitatively. For this purpose, the general people seeing the soccer games in the soccer grounds have been the population, and 280 sampling objects have been selected out of them by simple random sampling. Out of the 250(89.3%) collected questionnaires, 213(76.1%) questionnaires, excluding those questionnaires are those whose answers are insincere or some parts of which are missing, are as valid samples. As the measuring instrument for this study, the measures of Aaker (1997) are used, and the questionnaires used by Yu, Taeyong(1990) are revised and restructured to be fit for the purpose of the study. The method of the statistical analysis used to find out the influences of the pro soccer teams on the images of businesses are the covariance structure analysis. The findings concerning the structural models obtained on the basis of the methods of the study and the analysis of the data are as follows: The analysis of the images of the pro soccer teams on the images of businesses show that the factor of credibility influences the intellect, vividness, inhumanity and solidity, the factor of certainty influences vividness, solidity, the factor of advancedness influences inhumanity, wildness. On the other hand, the factor of interestingness doesn't influences the intellect, vividness, inhumanity, wildness, and solidity.

Objectives : We report an interim result of conformal radiotherapy in a patient with early stage cancer at the base of the tongue, which developed in a previously irradiated area. Materials and Methods : A 64-year-old male patient was diagnosed with T4NOMO supraglottic cancer. He received 72Gy of radiation therapy from 21 November 1988 to 24 February 1989. He had local failure and underwent a salvage total laryngectomy on 28 August 1989. Subsequently, he did well. In early 1999, he suffered from throat pain. He had a 2.5cm ulcerative mass at the base of his tongue, in the area that had been irradiated previously. Biopsy showed squamous cell carcinoma. After workup, he was diagnosed with base of tongue cancer with T2NOMO. Surgery was not feasible because the morbidity was not acceptable. Since it was difficult to re-irradiate the area with a curable dose using conventional 2D radiation therapy with an acceptable morbidity, we decided to try conformal radiotherapy. We used 7 static beam ports with field sizes from 7×6.4 to 8×8㎠, using 6 and 10MV photons. The fractionation regimen was 1.8Gy, 5 times per week. He received 64.8Gy in 36 fractions from 9 April 1999 to 1 June 1999. Results : In the 21 months since radiotherapy, the patient has not experienced any acute or chronic complications, such as xerostomia. He experienced relief of pain shortly after the start of radiotherapy, showed a complete response, and is still doing well. Conclusion : Conformal radiotherapy can be used to treat cancer that develops within a previously irradiated field, with curative intent.

Asbestosis is the disease of pulmonary fibrosis caused by the inhaled asbestos fibers, and could be diagnosed clinically, in the case of exposure history to asbestos is proved, by clinical symptoms of dyspnea or dry cough, physical examonation findings, and the radiographic features. But many othder inorganic dusts would show similar findings in the chest radiogram and sometimes the exposure history is obscure, so for the exact diagnosis of asbestosis lung biopsy is needed. In Korea, there have been some reports of survey in the workplace where asbestos is handled or of asbestos related diseases. This is a case report of asbestosis with accompanying pleural plaques, who had the occupational exposure to asbestos for 30 years and the consistent clinical, radiographic and pathological findings in the lung tissue obtained by the videoscope assisted thoracoscopic biopsy(VATS).
