Background : In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. Objective & Methods : For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results : In 1997. 99 strains of N. gonorrhoeae were isolated, among which 45(45.5%) were PPNG. Conclusion : The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 45.5% in 1997.

This paper attempts to review and trace back to, based on the data collected during visits of Japanese universities and research institutes, the organizational characteristics, the structures of curricula and study trends, with regard to the fields of social sciences, especially economics and business administration. One of the most conspicuous characteristics observed in academic organizations was Tsukuba university's system whose academic institution was organized around academic grouping, academic genealogy, and specialty: particularly social economic planning belonged to the genealogy of social engineering, in light of its characteristics in term of curriculum, seems to meet the contemporary need. There found two speciality areas in the Department of Social Engineering at the Graduate School: one is the concentration on Mathematical Planning and the other Management Engineering. Considering that its academic goal is tosys tematically and empirically analyze the human behaviors, and to take interdi-sci plinary approach through a policy-oriented system in doing so, it reflects one of the true natures of the academic trend. Their curricula appear to emphasize on analytical methods under uncertainty, application of mathematical planning techniques, system simulation, and information system design and its application, in the area of economics and business administration. Physical education is believed to require modernized facilities and equipments for its record-breaking and technical enhancement, and so increased investment in physical facilities and policy considerations for the training of physical educators are necessary.

적응 신경망 수신기를 이용한 DS/CDMA 다중사용자간섭(MAI) 제거

김재수,김창선,김성곤,변건식 동아대학교 2001 大學院論文集 Vol.26 No.-

The capacity of direct-sequence code-division multiple-access (DS/CDMA) systems is co-channel severely limited by multiple access interference (MAI) produced by the other users. To improve the capacity, joint-detection receivers and MAI cancellation techniques have been proposed.[1][2][3] This paper presents an adaptive neural network-based receiver that has the capacity of combating the 'near-far' problem and rejecting the multi-user interference in a multipath channel.[4] A comparative performance analysis of the conventional receiver and the adaptive neural network receiver is camel out using a Monte Carlo simulation. It is found that the new receiver performs extremely well in multipath and multiple access channels with a significant 'near-far' effect.

Objectives : We investigated the effects of naltrexone on acute alcohol response, stimulant and sedative, in healthy social drinkers using two doses of alcohol intake. Methods : Twenty four healthy male medical students were voluntarily participated. The experimental method was Cross-over design, Subjects received 25 mg/day or 50 mg/day of naltrexone on the experimental days. Biphasic Alcohol Effects Scale (BAES), alcohol craving, and blood alcohol concentration (BAC) were measured before drinking and at 15, 30, 45, 60, 90,and 120 min after drinking. Results : 1) Group of 0.6 mg/kg of alcohol intake. When the scores of stimulative subscale of BAES were compared bet-ween the naltrexone and control group, the scores were significantly lower in the naltrexone group at 15 and 90 min after drinking. Alcohol induced sedative effect was significantly higher in the naltrexone group at 90 min after drinking. The alcohol induced alcohol craving at 45 and 60 min after drinking was significantly lower in the naltrexone group as compared to the control. 2) Group of 0.3 ing/kg of alcohol intake. The alcohol induced stimulative effect evident in the control group seen in the time span of 15 to 45 min after drinking was not seen in the naltrexone group. The increase of alcohol induced alcohol craving noticed at 30 min after drinking in the control group was not seen in the naltrexone group. BAC at 15 min after drinking was lower in the naltrexone group compared to the control. Conclusion : Naltrexone is suggested to attenuate stimulative effect, to intensify sedative effect, and to block alcohol induced alcohol craving. These triple actions might be utilized for treatment and prevention of relapse of alcohol dependence.

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.

Abstract- In a plasma source ion implantation, the target is successively biased by negative voltage pulses with an intrinsic finite rise time, resulting in the time-dependent sheath formation around the target. Measurement of time-dependent sheath during the pulse rise show the ion matrix sheath development which is in proportion to square root of time and pulse rise rate over plasma density but independent of the ion mass.

스트레스 반응에 중요한 역할을 하고 있는 CRHR1 유전자 SNP와 알코올 의존과의 연관성에 관한 선행 연구들이 있다. 이에 본 연구는 백인을 대상으로 조사했던 기존연구와는 달리 한국인 남녀를 대상으로 하여 알코올 의존군과 정상 대조군의 CRHR1 유전자형 빈도 및 대립유전자형 빈도를 비교하였다. 본 연구의 연구대상자들은 알코올 의존군 268명(남자 218명, 여자 50명)과 정상 대조군 137명(남자 78명, 여자 59명)이었다. CRHR1 유전자 SNP를 SNP database와 선행연구를 근거로 선정한 후, 연구 대상자들의 이러한 SNP 유전자형을 PCRRFLP방법으로 조사하였다. 그 결과, 한국인의 CRHR1 유전자 SNPs로 7개(rs242938, rs404623, rs28364027, rs16940686, rs937, rs878886, rs878887)가 분석되었다. 이중 rs28364027의 A 대립 유전자의 빈도는 남녀 각각에서 알코올 의존군이 대조군보다 유의하게 높았다. 그리고 rs28364027의 AA 유전자형 및 A 대립 유전자와 rs878886의 CC유전자형 및 C 대립유전자의 빈도는 알코올 의존군내에서 여성이 남성보다 유의하게 높았다. 이러한 결과를 종합해 보면 CRHR1 유전자 SNP가 알코올 의존의 유전적 원인의 중요한 요인일 가능성을 제시하고 있다. 또 이러한 CRHR1 유전자 SNP가 알코올 의존의 유전적 원인에서 남녀간 차이를 설명할 수 있을 가능성도 시사하고 있다. Objectives:There were several preceding studies investigating the association between alcohol dependence and corticotropine releasing hormone receptor1(CRHR1) gene SNPs that play an important role in response to stress. The frequencies of CRHR1 genotypes and alleles were compared between alcohol-dependent patients and normal control subjects. Methods:The subjects were 268 alcohol-dependent patients(218 males, 50 females) and 137 normal controls(78 male, 59 female). CRHR1 gene SNPs were investigated according to the SNP database and the results from previous studies, and their genotypes were analyzed by polymerase chain reaction(PCR) and restriction fragment length polymorphism(RFLP). Results:Seven CRHR1 gene SNPs(rs242938, rs404623, rs28364027, rs16940686, rs937, rs878886, rs878887) were found in Korean subjects. The frequency of rs28364027 A allele was significantly higher in alcohol-dependent patients than normal controls in both genders. In alcohol-dependent patients, the frequencies of AA genotype and A allele of rs28364027, and of CC genotype and C allele of rs878886 were higher in female than male. Conclusion:These results suggest that CRHR1 gene SNP is one of the important genetic factors in the etiology of alcohol dependence. And also it is supposed that the different frequency of SNP genotype could explain stress-related gender difference in the genetic etiology of alcohol dependence.

Objectives : This study was designed to find possible effect of pregnancy and parturition on spatial memory, especially in relation to levels of estrogen during the third trimester and postpartal period in rats. Methods : 25 female Sprague Dawley rats were divided into pregnant group (N= 14) and control group (N= 11). Changes in spatial memory during 6 weeks including third trimester and postpartal period were measured using Morris water maze. Time to reach the platform in the maze was indicator of spatial memory. Serum estrogen level was measured on 1 week before delivery, postpartal day 1, and day 14. Results : Both groups showed gradual improvement in performance by trial days and weeks, but no significant difference was found between the two groups. However in the third trimester, pregnant group showed a trend of less achievement on 3 days of learning than control group. Serum estrogen levels did not differ significantly between groups over the 6 weeks of period. However there was positive correlation between serum estrogen level on postpartum day 1 and time to reach platform on postpartum week 2, and negative correlation between estrogen level on postpartum day 14 and latency to the platform on postpartum week 5. Conclusion : These results imply that changes in the serum estrogen level may have dual effects on the spatial learning in peripartal period. It is suggested that decline in cognitive function might occur either by failure of rapid decrease of estrogen, immediately after parturition, or retarded restoration of estrogen in later postpartal period.

Objetives : In order to provide useful data tbr the further clinical studies with Korean alcohol-dependent patients, enrollment and non-relapse rates were investigated while alcohol-dependent patients wcre followed up for 24 weeks. Methods : The subjects of this study were alcohol-dependent male patients who, for the first time, visited a hospital among 3 groups of hospitals, University Hospital, General Hospital or Mental Hospital, or those who needed to be followed up after discharge from those hospitals. After assigning 12 subjects to each hospital, we investigated enrollment and non-relapse rates while cognitive-behavioral therapy and pharmacotherapy were provided. Results : 1) Forty-eight patients were enrolled and the rate of enrollment was 36.4%. The enrollment rate in the University Hospital group was 52.1%, in the General Hospital group 50.0%. and in the Mental Hospital group 10.4%. 2) In 48 patients, non-relapse rate was 27.1% at 12 week and 18.8% at 24 weeks after starting follow-up. It was 24.4% and 20.0% at 12 and 24 weeks, repectively, in the University Hospital group while the General Hospital group showed 33.3% and 16.7%, respectively, and the Mental Hospital Group showed 20.0% at both 12 and 24 weeks. Conclusion : These results provide important data for further clinical studies of Korean alcohol-dependent patients.
