정인원,김헌,홍주봉,지경환,이규영 大韓神經精神醫學會 2002 신경정신의학 Vol.41 No.6

연구목적 : 알코올 대사와 중추신경계내의 알코올 작용부위와 관련한 일부 후보유전자들이 알코올 의존과 관련이 있는지를 확인하고자 하였다. 방 법 : DSM-IV로 진단된 알코올 의존 환자 128명과 정상 대조군 128명을 대상으로 후보 유전자들의 다형성을 중합효소 연쇄반응과 제한효소처리법을 이용하여 동정하였다. 여기서 분리된 대립유전자와 유전자형에 따른 빈도의 차이를 유전자별로 각각 비교하였으며, 알코올 의존에 작용하는 서로 다른 유전자들에 의한 영향력을 배제하기 위하여 logistic regression 분석을 적용하였다. 결 과 : 알코올 의존군에서는 ALDH_2 유전자의 NN(wild type)형이 정상대조군에 비하여 유의하게 많았다(chi-square test, p<0.001). logistic regression analysis를 통하여 다른 유전자들에 의한 영향을 보정한 상태에서 ALDH_2가 NN(wild type)인 경우 다른 아형에 비하여 알코올 의존에 대한 odds ratio는 130.312이며 그 신뢰구간은 (17.22, 986.43)이었다. 한편, ASA는 N-glycosylation 부위에 변이형 대립유전자를 갖고 있는 경우(AG or GG)는 wild type에 비하여 알코올 의존에 대한 위험도는 2.344배이며 그 95% 신뢰구간은 (1.128, 4.871)이었다. 결 론 : 알코올 의존과 ALDH_2 유전자간에는 밀접한 연관성이 확인되었다. 또한 다른 유전자들은 개별 연관분석에서 의미있는 연관성이 관찰되지는 않았지만 logistic regression analysis를 통하여 N-glycosylation 부위에 다형성이 있는 ASA 유전자가 알코올 의존과 관련이 있음을 시사하였다. Objectives : This study was to explore the association between alcohol dependence and five candidate genes related to the metabolism of alcohol and the enzymes of the suspected sites in CNS. Methods : The genotype and allele frequencies of five candidate genes in 128 male hospitalized patients who met DSM-IV criteria for alcohol dependence were compared with 128 age-matched healthy male control subjects using polymerase chain reaction and restriction fragment length polymorphism. A logistic regression analysis was applied in order to exclude the reciprocal interactions among five candidate genes. Results : The NN genotype frequency of the ALDH_2 gene was significantly higher in alcoholic patients than in control subjects(chi-square test, p<0.001). No difference in frequency was found in the other four genes. In a logistic regression analysis, the odds ratio for alcohol dependence in the NN genotype of the ALDH_2 gene and AG or GG genotypes of the N glycosylation site on the ASA gene were 130.312(95% confidence interval, 17.22-986.43) and 2.344(95% confidence interval. 1.128-4.871), respectively. Conclusion : The result reiterates the association of the ALDH_2 gene polyporphism and the alcohol dependence. Logistic regression analysis additionally suggested that the N-glycosylation site on the ASA gene was associated with alcohol dependence.

The cut-off values and related factors for total cholesterol of serum in normal Korean adults were studied from March to October, 1995, based on the data of 1,818 healthy adults of human involved the male and female. The comparisons of the serum total cholesterol levels were analyzed by sex, age, systolic blood pressure, diastolic blood pressure, body weight, height, PIBW, BMI and other biochemical tests. 1. The serum total cholesterol level were 194.4 mg/dl in total group, 186.9 mg/dl for male, and 197.6 mg/dl for female. 2. There was no significant differences by sex among the 21 to 50 ages group, but significantly higher in women than in men over 51 years old. 3. In general, the levels of serum total cholesterol were increased with age, the highest level in men was 192.7 mg/dl in 51 to 60 years old, and 210.5 mg/dl in more than 60 years old in women. 4.

오치규,김주열 동서대학교부설연구센터 2001 연구센터논문집 Vol.4 No.1

In digital media fields, illustration is searching the developmental change in artistic procedures for mutual working computer program. This suggest the possibility that all of artist in this field is originally never been figured in old time stage. Therefore, art and science should be controlled in a ruled system, and the artist, viewer and computer would be a mutual cooperative relationship. However, the digital media requires basically drawing capacity, and suggestion the endless possibility.

율-왜곡 이론에 의한 H.263부호기의 성능 분석

황재정,황치규,박종필 群山大學校 情報通信技術硏究所 1998 情報通信技術硏究論文集 Vol.2 No.-

Rate-distortion theory means that the lower limit of transmission rate is determind according to the distortion quantity. This theory is fundamentally important factor in the visual system without visually sensitive distortion. Rate-distortion theory originating in the notion of information quantity is derived using probability distribution of orignal signal and measurement of distortion. In this paper, we develop the R(D) function with the distribution function of Gaussian and Laplacian, using the absolute error criteria and the square error criteria. Then we applied these functions to H.263 video coder at very low-bitrate. Though the Laplacian and Gaussian distribution can be applied, we show that the lowest point on which the rate becomes zero is lower in the case of Laplacian than in the case of Gaussian.

광주 · 전남의 상수원인 주암호 유역을 연구대상지역으로 선정하여 GIS를 이용하여 수질 오염부하량을 계산하였다. 계산방법은 점오염원 부하량과 비점오염원 부하량을 나누어서 산정하였는데, 점오염원 부하량은 생활하수, 축산폐수, 산업폐수, 양어장폐수, 식당과 숙박업소의 배출수 등을 고려하여 원단위를 이용하여 산정하였고, 비점오염원 부하량은 SCS의 유출곡선지수(CN)를 기초로 해서 산정한 유출량과 환경부에서 우리나라 유역의 특성에 맞게 제시한 토지이용별 기대평균농도(EMC)를 적용하여 산정하였다. 계산된 점오염원 부하량과 비점오염원 부하량을 합하여 전체 오염부하량을 산정하였다. Juam Lake, which is the source of water supply to Chonnam province and Kwangju city was selected as a research site and water quality pollutant loads were calculated in this site. Point source pollutant loads and nonpoint source pollutant loads were calculated respectively. Point source pollutant loads were estimated using the unit pollutant loads of residence wastewater, farm wastewater, industrial wastewater, fish-farmer wastewater, wastewater of restaurants and lodgings presented by the Ministry of Environment, The direct runoff based on SCS Curve Number method was multiplied by Expected Mean Concentration to give nonpoint source pollutant loads. Total pollutant loads were calculated by summing up point and nonpoint source pollutant loads.

The pandemic influenza (H1N1 2009) virus, after being introduced in Korea in April, 2009, spread rapidly nationwide in mid-2009. This study was conducted to characterize trend in age distribution of visitors to Flu-clinics during the pandemic. Demographic, clinical and laboratory data of visitors to flu clinic from Week 36 to 52 (August 30 to December 26) of 2009 were retrieved and collected from electronic databases at 9 hospitals. Visitors 0-6, 7-12, 13-18, 19-29, 30-64, and 65 years or more of age were classified into group I to VI, respectively. A total of 107,467 visitors were seen at Flu-clinics for a 17-week study period. Of those, 32,485 were laboratory-confirmed. Antivirals were prescribed for 62,533 visitors. Numbers of visits, prescriptions of antivirals, and laboratory-confirmed cases of the pandemic influenza (H1N1 2009) peaked at Week 44. A large number of visits by group II and III were followed by those of group I and V, especially around the peak. Numbers of visits by group VI were lowest in all hospitals. In some hospitals, higher number of visits lasted longer in children than in adults while vice versa in other hospitals depending on the location. In summary, the pandemic influenza (H1N1 2009) was presumed to peak in late October and involved majorly children and students in Korea. Unique age distribution of visitors to flu clinic was observed in some hospitals.
