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.

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.

In the upper gastrointestinal tract, in particular, there are parts consisting of esophageal sphincter muscles to carry out physiologic functions, which causes impairments when removed, as well as such complications as mucosal injuries, bleeding and even perforations in the case of foreign bodies with large size and/or sharp angles. Therefore, it is essential to use an appropriate type of supplementary instrument for a safe procedure. Frequently utilized supplementary instruments are overtube, protector hood, latex glove and transparent cap. We report a case in which authors were successful in removing a watch bend consisting of metal ring from gastric body while using a modification of a widely available drip chamber of fluid set attached to vertical end of endoscopic device.

Objectives : Since mid-90s there have been numerous studies to understand and establish the concept of internet addiction as one of diagnostic classifications in psychiatry. Among them, many studies on the personality characteristics of internet addiction have been conducted. Recently, interests are expanding to temperament characteristics of internet addictors but the subjects have been limited to adolescents, In this study, the temperament characteristics of internet addiction in adults were investigated using Tridimensional Personality Questionnaire (TPQ). Methods : 430 participants (189 males, 241 females) answered the on-line and off-line questionnaires from January to December in 2005. Participants completed questionnaires on demography and the onset of internet use, Young's Internet Addiction Scale and Korean Contracted Version of Cloninger's Tridimensional Personality Questionnaire (TPQ). Rcsults : There were statistically significant differences in age, marital status, occupation, psychiatric history, smoking history, alcohol history and onset age of internet use among non-addiction, overuse and addiction groups by Young's scale. Of the TPQ items harm avoidance (HA) scores were significantly higher in addiction and overuse groups than non-addiction group. Reward dependence (RD) scores were significantly lower in addiction group than non-addiction group. Novelty seeking (NS) scores were significantly higher in addiction group than non-addiction group. Conclusion : This study suggests a significant difference of novelty seeking in temperament characteristics between adults and adolescents with internet addiction. Further studies are expected for profound understanding of internet addiction.

Genetic Algorithms have been successfully applied to various problems (for example, engineering design problems with a mix of continuous, integer and discrete design variables) that could not have been readily solved with traditional computational techniques. But, several problems for which conventional Genetic Algorithms are ill defined are premature convergence of solution and application of exterior penalty function. Therefore, we developed an Improved Genetic Algorithms(IGAs) to solve above two problems. As a case study, IGAs is applied to several nonlinear optimization problems and it is proved that this algorithm is very useful and efficient in comparison with traditional methods and conventional Genetic Algorithm.
