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.

Note-Taking as a Self-Regulated Learning Strategy and Cognitive Style : Impact on Immediate and Delayed Learner's Academic Performance

Chung, Jae-Sam,Ki, Hye-Hee 이화여자대학교 사범대학 교과교육연구소 2004 East west education Vol.21 No.-

This research was to investigate the impact of cognitive style and self- regulated learning strategy such as note-taking methods on learners' students' academicper formance. Statistical analysis result showed that both cognitive style and note-taking methods did not have a significant effect on an immediate test.However, there is a significant main effect of cognitive style on a delayed test. Field-dependent students significantly outperformed field-independent students on the delayed test. Also, the main effect of note-taking methods on the delayed test was significant. Students who took notes in a matrix scored higher on the delayed test than did students who took notes in a free format.

Most of the laws and standards relevant to technology in Korea bear a resemblance to those in Japan. Electricity was not introduced to Korea until Lighting ceremony in Kyong-Bok palace observed in 1887. Since Korea was annexed to Japan in 1910 and our public works were under Japan control we have applied Japanese laws and regulations made by Chosun government-general. Independently from Japan the power electricity accepted power plants of USA, codes of NESC, ASME / ANSI, NEMA. Our generation and distribution system takes American style while our consumer side takes Japanese style. As global trade system was transferred GATT into WTO, the harmonization of technological standards, certification construction testing in the trend of world. This paper is based on WTO / TBT agreement coming in effect after 12th, April, 1979. For Korea the distribution system has a strong resemblance to American system so that unconvertible because IEC 60364 originated from Europe while NEC originated from USA. This papers deals with the fundamental elements of electrical safety system with comparing IEC 60364 with NEC. This paper considers how engineers should apply NFPA 70(NEC) and IEC based on the comparison of NEC to IEC in relation to electrical installations.

Chung,Young-Ki,Jung,Jong-Wook,Kim,Jae-Chul,Kwak,Hee-Ro,Lee,Su-Kyung 한국화재소방학회 1997 한국화재소방학회 학술대회 논문집 Vol.1997 No.-

This paper investigates and analyzes the installation and failure status of mold transformer being used in domestic subways and describes the extinguishing process by time through the combustion test of winding part of mold transformer. Condition of installed mold transformers and classes of fire were surveyed and the mold transformer was burned in a horizontal heating furnace. It was confirmed that the mold transformer is self extinguishing and nonflammability. According to this results, the suitable standard of fire protection for the mold transformer was demanded after review of domestic and abroad law. It is expected that the cost of fire protection equipment can be reduced by using the status and combustion test result of mold transformer.

Uncertainty Channel between Inflation and Output Growth in Japan and Korea

Chung,Sang-Kuck,Kim,Seong- Ki 한국무역연구원 2014 무역연구 Vol.10 No.1

Bivariate ARFIMA and ARMA-GARCH-M models are used to explain the relationship between uncertainty and average outcomes for inflation and output growth. To analyze the quantitative importance, the effect of an inflation (output) surprise on inflation (output growth) uncertainty, average inflation and output growth were considered. Empirical results show different effects of uncertainty on inflation and growth. For the Japanese economy empirical results provide strong empirical confinnation of Friedman s hypothesis. Bivariate ARFIMA-GARCH-M model also provides a statistical support for Cukiennan and Meltzer s, Deveraux s, and Black s are all statistically significant, but the coefficients for Deveraux s and Black s are negative. For the Korean economy from ARFIMA-GARCH-M models, the Friedman and Deveraux s hypotheses do hold, but two other hypotheses do not obtain statistical support.

Most Technological laws of Korea are almost identical to those of Japan. Electricity was not introduced to Korea until lighting ceremony in Kyong-Bok palace observed in 1887. Since Korea was annexed to Japan in 1910, Korea have applied Japanese law and regulations made by Chosun government-general. And public works were under Japan control. Korea accepted adopted the power plants of America, codes of NESC, ASME / ANSI, MEMA while Japan accepted or adopted only IEC. Our generation distribution system takes American style while our consumer side takes Japanese style. As global trade system was transferred GATT into WTO, the technological standards, certification, construction and testing are in harmony internationally. The WTO / TBT agreement came in effect after 12th, April, 1979. The sections in the agreement require the members to exchange their own standards and codes for the harmonized ones by degree. The Korean distribution system has a strong resemblance to American system so that the internal engineers are confused in application of the relevant standards. IEC60364 and NEC are technologically similar but practically unconvertible because both have their different originality, that is to say Europe and USA. This paper deals with the fundamental elements of electrical safety system on review of IEC 60364 and NEC. This paper considers how engineers should apply IEC60364 and NFPA 70(NEC) based on all-the-way review of them.

敎授 學習過程과 Communication의 理論的 考察

曺正基 新羅大學校 1984 論文集 Vol.17 No.-

The present issue in Modern education is apparently to increase the potentials of studying by students-themselves. To solve this problems, the process of teaching-learning looks very important. According to our viewpoint, teaching-learning could be difined in two-different ways. S.M. Corey difined the teaching as follow;To teach the Individual to show particular action as a response to a situation under a given condition and manipulate the environment with intention that surrounds him to participate in particular action. Also, A.T. Gates, defines "lerning is the progressive acceptance of behavior through experience and traing. Cho Chung-Ki, defines the teaching in his book (Human Management, 1981, p. 100) as follow;the communication is taking of one's own knowledge, thought and attitude by all and is the process that express and transmit his opinion to others. With this concept, teaching-learning process could be regarded as process of Communication. Because the basic function of Education is to transmit the cultural legacies, accumu- lated through history, from the old generations to New generations, I could possibly prove that teaching & instruction would be the process of communi-cation. In other words, the teacher, who is transmitter, sends his message using his text and educational aids. And the student, the receiver, receiver the message and in-terpret these for learning. As a conclusion, the instruction would be possible by the help of Communication. To be effective in Education, the employment of the function and technique of Communication is mostly desired.

정인경,정재훈,민용기,이명식,이문규,김광원,정윤이,박중열,홍성관,이기업 대한당뇨병학회 2002 Diabetes and Metabolism Journal Vol.26 No.2

연구배경:아카보스와 보글리보스는 ­glucosidase inhibitors로써 비록 약리학적 작용이나 부작용에 있어서 두 약물간에 차이가 있다는 것은 잘 알려져 있으나 당뇨병 환자를 대상으로 아직 이에 대한 두 약물간에 직접적인 비교에 대해 연구된 바는 없었다. 이에 저자등은 국내 2형 당뇨병 환자에 대해 유효성과 부작용 발현에 대해 두 약제를 비교하고자 무작위법에 의한 위약 대조군의 이중 맹검법 연구를 시행하였다. 방법:시험 약제 투여 4주간의 관찰기를 설정하여 공복혈당의 변화가 30㎎/dL 이하이고, 식후 혈당이 200㎎/dL 이상인 환자로 기타 제외 기준에 해당하지 않은 환자 53명을 대상으로 하여 보글리보스 군(24명)과 아카보스 군(29명)으로 무작위로 나누었다. 치료기간은 총 8주로 하였으며, 4주간 간격으로 혈청학적 검사와 부작용을 분석하여 치료 효과가 부작용을 평가하였다. 결과:1)혈당 변화:보글리보스군은 식후 1시간 혈당이 치료 후 4주, 8주째 의미 있게 감소하였도, 아카보스군은 식후 1시간과 2시간 혈당이 치료 후 4주, 8주째 의미있게 감소하였다. 또한 관찰기 혈당에 대한 치료 4주째 감소량은 아카보스군에서 더 큰 경향을 보였으나, 치료 8주째에는 두 군 간의 강하정도에 의미있는 차이가 없었다(p=0.569). 2)인슐린 치의 변화:보글리스 군은 식후 1시간 인슐린 치가 치료 전에 비해 치료 4주, 8주째 감소하는 경향을 보였고, 공복 인슐린이나 식후 2시간 인슐린치는 치료전 후에 의미 있는 차이가 없었다. 아카보스군에서는 치료 전후로 공복 인슐린, 식후 1시간과 2시간 인슐린치에 의미 있는 차이를 보이지 않았다. 두약제 간에 치료 전과 치료 8주사이의 식후 2시간 인슐린의 감소량이 보글리보스 군에서 의미있게 높았다(p=0.040). 3)당화혈색소:보글리보스 군은 치료 전에 비해 치료후 당화혈색소가 감소하는 경향을 보였고, 아카보스군은 치료 전에 비해 의미있게 감소하였다. 당화혈색소 변화량은 두 군간에 의미 있는 차이는 없었다(p=0.412). 4)지질대사의 변화:중성지방, 콜레스테롤, 고밀도 진단백 콜레스테롤에 대해 두 군간에 의미 있는 차이는 없었다. 5)부작용:소화기계 부작용의 빈도는 치료 4주째 보글리보스 군에서 의미 있게 낮았으나(p=0.028), 치료 8주째 부작용의 빈도는 두 군간에 의미 있는 차이가 없었다(p=0.215). 결론:2형 당뇨병 환자에서 보글리보스와 아카보스의 두 약제의 임상적 유효성과 부작용발현에 대해 비교한 결과 치료 후 8 주 후 혈당강화효과는 두 약제간에 유사한 효과를 보였으나 보글리보스군에서 4주째의 초기 위장관 부작용이 적었다. Background : Acarbose and voglibose are alpha-glucosidase inhibitors. Although different pharmacological effects and adverse abdominal events associated with the two drugs have been reported, no study directly compared acarbose and voglibose in diabetes has been undertaken. To compare the pharmacological effects and gastrointestinal adverse events between two drugs, a randomized, placebo-controlled, double-bind study was performed in type 2 diabetes patients. Methods : The period of study was 12 weeks(observation period: 4 weeks; treatment period: 8 weeks). Fifty-three patients were randomized into two groups(the acarbose group: 24 patients; the voglibose group: 29 patients). The serum glucose, insulin, fructosamine, HbA_1c, cholesterol, triglyceride and the incidence of adverse events were measured. Results : 1) The reduction of glucose from before treatment to 4 weeks after treatment was significantly higher in the acarbose group, but the change before treatment and 8 weeks after treatment in the two groups was similar(p=0.569). 2) The insulin significantly decreased after voglibose treatment(p=0.040). 3) HbAa_1c level tended to decrease in voglibose group, and there was a significant decrease after acarbose treatment. However, the change in HbA_1c level before and after treatment was similar between the two groups(p=0.412). 4) The two drugs did not cause any other changes in the total, HDL-cholesterol and triglyceride. 5) The number of patients with gastrointestinal adverse events was significantly low 4 weeks after voglibose treatment (p=0.049), but the incidence in the two groups was similar after 8 weeks(p=0.215). Conclusions : Acarbose and voglibose significantly improved postprandial hyperglycemia in diabetes. The incidence of gastrointestinal adverse events was low 4 weeks after voglibose treatment(J Kor Diabetes 26:134~145, 2002).

The fate of spinal schwannomas following subtotal resection: a retrospective multicenter study by the Korea spinal oncology research group.

Sohn, Seil,Chung, Chun Kee,Park, Sung-Hye,Kim, Eun-Sang,Kim, Ki-Jeong,Kim, Chi Heon M. Nijhoff ; Kluwer Academic Publishers 2013 Journal of neuro-oncology Vol.114 No.3

<P>The fate of residual spinal schwannomas needs to be estimated in order to plan further management after subtotal removal. Our aim was to evaluate the growth rate of residual spinal schwannomas and compare results in regrowth and no regrowth groups by using data collected from the Korea Spinal Oncology Research Group database. From January 1989 to August 2011, 27 patients with residual spinal schwannomas were selected. Patients with at least two follow-up magnetic resonance image (MRI) studies after subtotal resection were included. The mean period of MRI follow-up was 62.4 months. A tumor size increase of over 2 mm in the maximal diameter was considered indicative of regrowth. Age, sex, size at initial diagnosis, postoperative tumor size, and Ki-67 labeling index were compared between regrowth and no regrowth groups. Eight residual schwannomas regrew (29.6 %), and 19 (70.4 %) did not regrow. Average growth rate of the regrowing tumors was 1.0 4.4 mm/year. The mean percentage increase in tumor size during follow-up was 10.0 28.8 %. The Ki-67 labeling indices were significantly different between regrowth and no regrowth groups (P = 0.014). Two patients underwent a revision operation for significant tumor regrowth. Nineteen cases (70.4 %) among 27 residual spinal schwannomas did not regrow significantly, but further surgical treatments were necessary in 2 patients due to significant regrowth. The Ki-67 labeling index was higher in the regrowth group. Earlier follow-up MRI is recommended for patients whose tumors have higher Ki-67.</P>
