This study was conducted to estimate the effective population size using SNPs data of 240 Jeju horses that had raced at the Jeju racing park. Of the total 61,746 genotyped autosomal SNPs, 17,320 (28.1%) SNPs (missing genotype rate of >10%, minor allele frequency of <0.05 and Hardy-Weinberg equilibrium test P-value of < $10^{-6}$) were excluded after quality control processes. SNPs on the X and Y chromosomes and genotyped individuals with missing genotype rate over 10% were also excluded, and finally, 44,426 (71.9%) SNPs were selected and used for the analysis. The measures of the LD, square of correlation coefficient ($r^2$) between SNP pairs, were calculated for each allele and the effective population size was determined based on $r^2$ measures. The polymorphism information contents (PIC) and expected heterozygosity (HE) were 0.27 and 0.34, respectively. In LD, the most rapid decline was observed over the first 1 Mb. But $r^2$ decreased more slowly with increasing distance and was constant after 2 Mb of distance and the decline was almost linear with log-transformed distance. The average $r^2$ between adjacent SNP pairs ranged from 0.20 to 0.31 in each chromosome and whole average was 0.26, while the whole average $r^2$ between all SNP pairs was 0.02. We observed an initial pattern of decreasing $N_e$ and estimated values were closer to 41 at 1 ~ 5 generations ago. The effective population size (41 heads) estimated in this study seems to be large considering Jeju horse's population size (about 2,000 heads), but it should be interpreted with caution because of the technical limitations of the methods and sample size.

목적 : 가와사끼 병의 뇌파 소견 및 다른 임상인자들과의 연관성을 알아보고자 하였다. 방법 : 1994년 1월부터 1995년 12월 사이에 순천향대학 천안병원 소아과에 입원한 23명의 신경학적으로 정상인 가와사끼 병 환아에게 뇌파검사를 실시하여 이를 검사시기, 성별, 연령, 혈소판, 간기능 검사치, 그리고 동맥류 유무등의 임상인자들과 비교하였다. 결과 : 이상뇌파가 23명중 52.2%인 12명에게서 관찰되었으며, 이상뇌파로는 예파 및 극파, 극·서파 복합 양상과 전반적인 배경파의 서파양상이 나타났다. 뇌파의 검사시기가 진단부터 1주 이내인 경우에 이상뇌파의 빈도가 그 후보다 의미있게 높았으나, 그 밖의 다른 임상인자와의 연관성은 별 의미가 없었다. 결론 : 가와사끼 병 초기에 이상뇌파가 나타나는 것은 비록 신경적 증상은 없지만 중추 신경계가 영향을 받는다는 간접적인 증거로 생각할 수 있어 향후 신경적 합병증 발생 여부에 대한 면밀한 관찰이 필요하다고 생각된다. Purpose : This study is to find out if there is any association between EEG abnormalities in Kawasaki disease with other clinical factors. Methods : We performed EEG in 23 Kawasaki disease patients without any neurologic sign who admitted in Soonchunhyang Chunan Hospital from 1994. 1. to 1995. 12. and compared it with sex, age, platelet count, liver function test and presence of coronary artery aneurysm. Results : Abnormal EEG findings were observed in 12 of 23 patients(52.2%) and as for abnormal EEG findings, sharp, spike, spike & slow wave complex, and generalized slow background activity were noted. When EEG was performed within a week after the diagnosis, the incidence of abnormalities of EEG increased significantly but there was no correlation with other clinical factors. Conclusion : EEG abnormalities in the early stage of Kawasaki disease indicate that although there is no abnormal neurologic signs clinically, central nervous system might be affected and there should be a close observation for the developement of neurologic complication.

The Working Group on the revision of Clinical Research Methodology for Acupuncture met in Seoul, Republic of Korea from 24 to 26 August 2005. The main objectives of the meeting were to review the regional publication guidelines for Clinical Research on Acupuncture, to make necessary revisions in the guidelines, to make recommendations on further collaboration and activities in the field of research on acupuncture, and to discuss scientific evidence-based approaches in the clinical research on acupuncture. Fourteen members from the eight Member States, one secretariat staff from the WHO Regional Office for the Western Pacific and ten observers from the Republic of Korea attended the meeting. The members presented their papers to review the current status of clinical research on acupuncture. The drafts of proposed revision to the previous guidelines for clinical research methodology on acupuncture were discussed extensively. The issues covered during the discussion included: the definition of the new terms; reorganization of clinical research design; revision and update of contents (e.g., control group); introduction of Institutional Review Board (IRB) on the section of ethical approval; additional outcomes including health-related quality of life (HRQOL), qualitative measures, etc. In the course of these discussions, the working group developed the revised guidelines for clinical research on acupuncture and made recommendations for promoting the dissemination of the revised guidelines.

This paper describes an intelligent cruise control system for automobile. With the remarkable numericalincrease of automobiles on the roal, the optimized traffic flow control using the cruise control is one of the very important traffic problems to overcome the limitation of an existing road capacity. Based onthis idea that minimize the fuel cost and teh air pollution, and accept a driver's needs for driving, we have developed an intelligent cruise control system for vehicle. This proposed intelligent fuzzy cruise controller was successfully implemented using the fuzzy algorithm, the i80c196 μ-controller board and the throttle valve actuator. The field test results on an linear road was introduced.

Recent experimental studies and clinical cases have suggested that grafting tissue from the adrenal medulla into the brain may alleviate the symptoms of Parkinson's disease. Autologous adrenal medullary grafts into the striatum was performed stereotactically in two patients with Parkinson's disease. Both patients were bedridden preoperatively, but 4 months after the surgery both became ambulatory and one was even capable of returning to his job. Even though the number of cases was small⑵ and the follow-up period was short, this study shows that adrenal medullary transplantation into the striatum may have some beneficial effects in patient with Parkinson's disease. Further experimental and clinical trials are necessary to see whether this procedure will be a recommendable surgical treatment for patients suffering from Parkinson's disease.
