Objectives : There are a number of preceding epidemiological studies reporting gender differences in the genetic etiology of alcohol dependence. The author investigated gender difference in the frequencies of ADH2 and ALDH2 genoypes between the patients with alcohol dependence and normal control. Methods : The subjects were 141 alcohol dependent patients (104 males, 37 females) and 138 normal control (79 males, 59 females). The frequencies of 1/1 and 1/2+2/2 (2+ afterward) genotypes for ADH2 and ALDH2 were investigated in male and female between alcohol dependence and normal control group. DNA was extracted from WBC in peripheral venous blood and PCR-RFLP method was used out for genotyping. Results : First, the frequency of ADH2 1/1 genotype was significantly higher in alcohol dependent patients than normal control in both genders. Second, while there was no gender difference in the frequency of ADH2 1/1 genotype in normal controls, in the patient group however, the frequency was significantly higher in females than males. Third, in male subjects with alcohol dependence, the frequency of ALDH2 1/1 genotype was significantly higher than in male normal control subjects. On the other hand, in female subjects with alcohol dependence, the frequency of ALDH2 2+ genotype was significantly higher than in female normal control subjects. Conclusion : These results suggest that while the risk of alcohol dependence is predominantly affected by ALDH2 1/1 geno-type in male, the female ADH2 1/1 genotype is mainly associated with the risk of alcohol dependence. This means that there are gender differences in the genetic etiology of alcohol dependence.

A 10-year-old intact female Miniature Schnauzer dog was referred with the primary complaint of persistentanorexia, remittent fever, vomiting and abdominal pain. Hemogram suggested a chronic inflammatory disease. Serumbiochemistry showed moderate hepatobiliary cellular damage with severe cholestasis. Abdominal radiography andultrasonography revealed hepatomegaly, choleliths and sludges in gall bladder and small stones in urinary bladder. Basedcholecystectomy and cystectomy, choleliths and uroliths were removed from gall bladder and urinary bladder,respectively. The clinical condition was dramatically improved after surgery.

홍용표ㆍ김웅용ㆍ신현곤(Yong Pyo HongㆍUng Yong KimㆍHyun Gon Shin) 유기성자원학회 2016 유기물자원화 Vol.24 No.1

본 연구는 음식물류폐기물 공공 자원화 시설 운영의 문제점과 제도 개선방안을 위하여 실시하였다. 현재 운영중인 음식물류 폐기물의 가동율 현황과 자원화 시설의 확충 계획에 대한 분석을 통해 시설의 무분별한 신규건설로 인한 국가의 예산이 낭비되지 않도록 그 대안을 제시하였으며, 그 결과는 다음과 같다. 공공 자원화시설 신규 확충보다는 기존 민간 자원화시설을 활용하여 예산을 절약하고 음식물류 폐기물의 안정적인 처리는 물론 자원순환을 촉진시킬 수 있는 정책전환이 필요하다. 음식물류 폐기물을 친환경적인 방법으로 안정적으로 처리하기 위해서는 제도개선이 필요하며, 이를 위해 민간 자원화시설 가동률 저하를 줄일 수 있는 준공영제 도입이 필요하다. 또한, 공공 자원화시설의 검증된 기술과 경제성 확보 방안 마련이 필요하다. This study is conducted to find out the problems of the public food waste recycling facility operation and its improvement. In order to save the national budget by analyzing plans to expand including operation rate for the food waste recycling facility, the alternative ways are suggested. The result can be as follows: Policy switch is required not only to save budget and stable disposal of food waste but also to promote resource recycling rather than expanding public facilities. In order to change the policy for stable and eco-friendly disposal of food waste, it is necessary to adopt semipublic system that prevent the decline of the rate of operation of private resource recycling facility. Furthermore, it is required to prepare both qualified technologies of public resource recycling and the ways of profitability secure.

포틀랜드 시멘트 페이스트와 몰탈의 특성에 미치는 실리카 흄 및 왕겨재의 영향

The effects of the silica fume and rice husk ash on the physical, chemical, and mechanical properties of portland cement mortars and pastes have been studied. When silica fume was added to partland cement with 3,6,9,12wt%, overall compressive strength strength was increased because the added silica fume was reacted with free lime resulting in the formation of new C-S-H phases. Among these, the cement mortars containing 9 wt.%, silica fume shows the highest compressive strength. On the other hand, the addition of rice husk ash to partland cement was not seemed to be much effective on compressive strength due to the larger particle size than silica fume.

Estradiol-17β를 처리한 흰쥐 자궁에 있어서 Clomiphene이 세포내 수용체, DNA 및 cAMP 농도에 미치는 영향

김곤섭,고복현 동국대학교 경주대학 1989 論文集 Vol.8 No.-

These experiments were carried out to investigate the study on the interaction of estradiol receptor and cAMP level of clomiphene in immature rat uterus. The results obtained were summarized as follow : 1. The binding affinity of clomiphene to estradiol receptor in uterine cytosol was lower than that of estradiol-17β. clomiphene inhibited the replenishment of the receptor to cystol in uterus(P<0.01). 2. DNA level in uterus was increased at 48 hours after estradiol-17β or clomiphene injection(P<0.01) 3. cAMP level in uterus was increased at 48 hours after estradiol-17β or clomiphene injection(P<0.01)

2차원 해석을 이용한 지하복합구조물 설계의 문제점 : 지하철 정거장을 중심으로

김형곤,조현영,정진환 釜山大學校生産技術硏究所 1997 生産技術硏究所論文集 Vol.52 No.-

본 연구에서는, 3차원 지하구조물이 2차원 뼈대조구조해석에 의해서 설계될 때의 문제점 들, 즉 갑작스런 단면의 변화, 개구부, 길이방향으로의 지반상태의 변화들이 검토 되어진다. 구조물들 3차원 해석에서 실제구조물과 가능한한 가장 근사하게 FEM에 의해 이상화되어진다. 본 연구로부터, 다음과 같은 두가지 결론을 내릴수 있다. 첫째, 개구부가 존재하는 곳에서는 보다 정확한 휨 모멘트분포를 얻기 위해 3차원이나 판이론에 의한 세부적인 해석이 수행되어져야 한다. 둘째, 건조수축, 수화열 그리고 힘의 분배에 대한 길이방향 보강을 결정하기 위해서는 더 세심한 검토가 필요하다. In this study, the problems when 3-D underground structures were designed by using 2-D plane frame structure analyses, such as sudden changes of sections, openings, and the variations of the ground conditions in the longitudinal directions, were investigated. The structures were idealized by FEM as close as possible to the real structures in 3-D. From this study, the authors conclude following two results. First, 3-D or detailed analysis with plate theory where openings exist must be carried out to obtain more accurate bending moment distribution. Second, a more refined investigation is needed to determine the longitudinal reinforcement due to shrinkage, the heat of hydration and the distribution of forces.

웨이블렛 변환을 이용한 정전 탐침 자료 분석 알고리즘 개발

김곤호,김대경,황순모,김용현 한양대학교 이학기술연구소 1999 이학기술연구지 Vol.1 No.-

ECR 식각 플라즈마에서 정전 Langmuir 탐침으로 얻은 자료의 해석을 위하여 Dauberchies 웨이블렛과 이중 직교 웨이블렛 변환을 이용한 새로운 알고리즘을 개발하였다. 이 알고리즘을 이용한 자료해석 방식에서는 해석자의 선택적 입력 값을 최소로 하고 자료의 잡음제거시 일반적으로 사용하고 있는 평균을 기초로 하는 통계적인 방법을 사용하지 않았다. 본 알고리즘에서는 Dauberchies 웨이블렛을 이용하여 자료의 저주파 성분만을 추출함으로 포화 이온 및 전자 전류성분을 변환 자료에서 직접 구하였다. 또한, 원시 자료의 1차 미분자료에 대한 이중 직교 웨이블레서 변환을 이용하여 플라즈마 전위를 직접 구할 수 있어 웨이블렛 변환을 거치는 과정에서 플라즈마 전자온도를 구하는 영역이 일관성 있게 정의되었다. 전자분포 모델은 ECR 플라즈마의 특징인 hot과 bulk의 두 가지 온도를 가지는 bi-Maxwallian 분포로 가정하고 Martquardt 방법을 사용한 비선형 fitting 방법으로 두 가지 전자 온도를 구하였다. 포화 이온 및 전자 전류 곡선의 플라즈마 전위에 해당하는 전류 값으로부터 플라즈마 이온 및 전자 밀도를 얻었으며 임의의 자료에 대한 알고리즘의 정확성 검사 결과 90%이상의 정확도를 보였다. A new algorithm for automating the analysis of Langmuir-probe traces taken from the ECR magnetized plasma is developed through the Daubechies wavelet and the bi-orthogonal wavelet transformations. This approach minimizes the operator-specified inputs and provides de-noised data without using the statistical method based on the averaging techniques. In this algorithm, the electron and ion current lines are obtained from the low frequency information of the Daubechies wavelet processed data. From the bi-orthogonal wavelet transform for the differentiated data, the plasma potential can be clearly determined. The region for obtaining the electron temperature can be systematically chosen from these processed data without operator-specified inputs. The electrons are modeled by a bi-Maxwellian distribution with hot and cold temperatures and nonlienar fitting method (a Martquardt method) is used to determine the electron temperatures from this region. Ion and electron plasma densities are obtained from the ion and the electron current at the plasma potential, respectively. The evaluation results by using the artificially generated data shows over 90% accuracy.
