연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

정지궤도 위성과 지구국간 광통신을 대기상태와 앙각의 함수로써 해석할 수 있는 한모델(Han's model)을 제시하였다. 한모델에서는 대기상태를 맑은날, 구름낀 날, 안개, 헤이즈, 비, 눈의 여섯가지 전형적인 상태로 구분한다. 비트오류을 $10^{-7}$을 만족하는 데이터 전송속도를 한모델을 이용하여 상향링크와 하향링크에 대해 해석하였다. 상향링크시의 포인팅손실이 하향링크시의 대기에 의한 공간 가간섭 저하보다 크기 때문에 데이터 전송속도는 하향링크 보다 오히려 상향링크시에 제한됨을 알 수 있었다. Han's model, which is able to analyze optical communication between earth station and geo-satellite as a function of atmospheric conditions and elevation angles. is presented. In Han's model, atmospheric conditions are roughly classified into six basic types; clear sky, cloud, haze, fog, rain and snow. Data rate satisfying for the BER below $10^{-7}$ is analyzed by Han's model in case of up-link and down-link, respectively. Data rate is more limited by up-link than by down-link because the pointing loss caused by atmosphere on the up-link is greater than the spatial coherence degradation caused by atmosphere on the down-link.

Reactive oxygen species(ROS) are implicated in the pathogenesis of a wide variety of human diseases. Numerous studies indicate that ROS may serve as common intracellular molecules that contribute to the process of nuclear factor(NF)κB activation in response to a diverse stimuli. In our laboratory, we have demonstrated tat antioxidants could reverse the decline of immune function caused by exercise-induced ROS. Furthermore, it in necessary to understand a mechanism underlying ROS-dependent disorder in biological system. Recent studies have been shown that several gene expression were regulated by oxidants, antioxidants and other determinants of the intracellular reduction-oxidation(redox) state. In this process, NF-κB have been shown to play a important role. The purpose of the present investigation was to evaluate the effect of exercise-induced oxidative stress and antioxidnt supplementation on NF-κB activation in peripheral mononuclear cells. Forty male SD rats(4 weeks old) were randomly divided into noraml diet group and antioxidants(ATO) supplement group, and then ATO groups were treated with antioxidants(VE: 2001U/kg, VC: 50mg/rat, β-carotene: 300mg/kg, vitamin B6: 250㎍/100g, selenomethionine: 0.1mg/kg) for 16 weeks. After 16 weeks breeding at each condition, each group divided into two groups: Control group(CR) fed generally, Exercise group(CE) fed generally and followed by acute exercise 16 weeks later. Antioxidant Antioxidants and Exercise group(AE) fed with antioxidants and followed by acute exercise. The activation of NF-κB binding activity was increased after exhaustive exercise bout in both group. In addition, pretreatment of ATO group with the antioxidants mixture lead to the inhibition of NF-κB binding activity. This results suggest that NF-κB activation should be further studies in response to a variety of exercise.

Among the hematologic complications of solid tumors, leukoerythroblastosis, DIO and MAHA have been known to be clinically significant According to the recent increasing incidence of cancer, these hematologic complications have been reported frequently. However, the simutaneous developement of such manifestations is rare. Recently, we have experienced a patient with gastric adenocarcinoma in which case severe bleeding tendency were observed and laboratory studies including bone marrow examination demonstrated the findings of leukoerythroblastosis, DIC and MAHA. She died of upper gastrointestinal bleeding despite the supportive care such as vlood transfusions. We should give attention to the findings of peripheral golld smear for the patient with malignancy and it is mandatory for therapeutic plan to perform bone marrow examination if the above mentioned hemorrhagic complications are suspected.

The purpose of this study was to evaluate the utility of the MR urography in patient with ureterohydronephrosis. Twenty-five patients with ureterohydronephrosis were researched by 1.5T superconducting unit with body coil. The causes of dilation were the follows: Ureteral benign stricture (n=10), ureteral stone (n=7), ureteral malignant stricture (n=6), and uretero-vesical reflux. (n=2). Coronal images were obtained by using a fat suppressed, respiratory-triggered, heavily T2-weighted fast spin echo sequences, and the images were processed by using a maximum intensity projection algorithm, We evaluated the technical success rate, the level and the cause of the obstruction. In 100%(25/25): of cases, MRU could be obtained successfully. The accuracy of MRU in the determining the level of the obstruction was 100%(25/25). The accuracy of the chagnosis of obstruction was 92%(23/25). MRU may be an effective chagnosis method for evaluating the ureterohydronephrosis without exposure of radiation or risks associated with lodinated contrast material. MRU may be alternative to IVU in patient with hydronephrosis.

Background: An association between Hashimoto's thyroiditis (HT) and papillary thyroid carcinoma (PTC) is still controversial. Studies to date established the coexistence of HT in 11% to 36% of PTC patients. BRAFV600E mutation was presented 90% with no HT, 64% with HT in PTC patients. Therefore, BRAFV600E mutation is associated with the pathogenesis of PTC arising in HT. The purpose of this study was to identify predictive factors for the coexistence of PTC and HT and to evaluate the association of the BRAFV600E mutation with the clinicopathological features of coexistence of PTC and HT. Methods: A total of 247 patients underwent surgery for thyroid disorders between January 2007 and April 2009. In all, 212 patients was diagnosed as thyroid papillary carcinoma only (PTC group), 33 had coexistence of PTC and HT (PTC+HT group), and 2 had been diagnosed with HT. DNA was extracted from paraffin embedded thyroid tumor specimens taken from 99 patients with PTC, 13 coexistence of PTC and HT, and 2 was HT. The presence of the BRAFV600E mutation was determined by polymerase chain reaction amplification of exon 15 followed by direct sequencing. Results: Among clinicopathological features sex, age, tumor size and capsule invasion was not significant between PTC group and PTC+HT group. Lymph node metastasis and stage was significantly lower in PTC+HT group than PTC group (p=0.044). BRAFV600E mutation was found in 34 of the 99 PTC group (34.3%), 1 of the 13 PTC+HT group and 2 HT show no BRAFV600E mutation. Conclusion: These data demonstrated that the coexistence of PTC and HT was less aggressive than PTC only.

It is obvious that, based on the fact that south Korea and north Korea have took the different ways respectively in the different ideologies and political systems from each other for the period of half a century since the Korean peninsula was divided into south and north after the liberation of Korea, they have seriously become different in all aspects, including politics, economy, society, culture and etc. and the educations in both have been also gradually getting different without overcoming the difference. Therefore this study is to compare and analyze the ideologies and object, the policy and the change of the curriculum of physical education in primary school of both. In the way of study, the physical education of both was compared and analyzed based on the treatise related to previous studies owing to difficulties in access to the materials. Chapter 2 has showed the ideology and the object, chapter 3 the policy, chapter 4 the change of curriculum, chapter 5 the system of curriculum, chapter 6 the comparison of physical education of primary schools in south and north korea. The conclusion has been showed in chapter 7. Consequently, it can be considered that the educations in both of south and north korea have had a great effect on the political systems of both: the education of south korea has success-fully contributed to the economic development of the liberal democracy and that of north korea has been successful for maintenance of the political system based on Kim Il-Seong's unique ideology. To narrow the gap of differences between south korea and north korea, it was suggested that the exchange of the children's sports activities which are most basic in education is a short cut.

The purpose of this study was to examine the relastionship between stress and immunologic function as a possible mechanism of stress and disease process. The authors investigated how the psychological stress induced by avoidance-avoidance conflict model or physical stress of electric shock do impact the immune function, measuring proliferation and interleukin-2(IL-2) production of rat splenic lymphocytes stimulated with various mitogens such as concanavalin-A(Con-A). phytohemagglutinin-M(PHA) and phorbol 12-myristate l?-acetate+calcium inophore A23187(PMA+A23187). In this experiment, female Sprag-Dawley rats were used an subjects. Animals were separated into 4 group according to different stress conditions. Conflict group received psychological conflict stress with electric shock depending on the coping behaviour and Yoked group was not in psychological conflict situation but received as same amount of electric shock as conflict group. Skinner-Box control group was immobilized without electric shock and Home-cage control group had no stress condition. The results are as follows : 1) There is significant difference in lymphocyte proliferation in case of Con-A and PMA+A 23187 between Skinner-Box control group and Yoked group at the high current condition. 2) There is significant difference in IL-2 production in case of PHA and PMA+A23187 between Skinner-Box control group and Yoked group. 3) There is more significant difference in lymphocyte proliferation in case of all of mitogens, Con-A. PHA and PMA+A23187 between Yoked group and Conflict group regardless of high or low current condition. 4) There is significant difference in IL-2 production in case of PMA+A23187 between Yoked group and Conflict group. This results suggest that psychological stress could reduce the immue function more profoundly than physical stress and also means the importance of coping and appraisal in the stress-immunology relationship.
