The study aimed to analyse and compare the various kinematic variables of Croise´ motion with A la seconde motion in order to provide improve-ment of understanding in the technique of ballet. And Fouett´ motion was divided into LSI(i.e., Leg-Stretching motion: A la seconde in French), LBI(i.e., Leg-Banding motion: Coupe´ in French), LS2 and LB2. To achieve of such the purpose, six ballerina were sampled as subjects with 5-year career at university and the motions were required to be performed as quickly and stably as possible. The motions were analysed using the DLT method of three-dimensional cinematography. The principal kinematic variables for comparative analysis between Croise´ and A la seconde were as such: spent time, c.o.g distance, angular velocity of both arms, lean angle, hip joint angle and height of c.o.g. As a result of analyzing the data, the following conclusions were drawn. 1. The overall duration of Croise´ is less than that of A la seconde, but there was no significant difference two motions. 2. C.O.G. distance in Croise´ in view of horizontal plane tend to be shorter than that in A la seconde, but there was no significant difference between two motions. 3. The angular velocity of right arm in Croise´ is larger than that in A la seconde only at LS. There was no significant difference in the angular velocity of left arm in two motions, but the angular velocity f left arm in A la seconde tend to be larger than that in Croise´both at LSI and at LS2. and the angular velocity of left arm un Croise´ tend to be larger than that in A la seconde both at LB1 at LB2. 4. There was no significant difference in the lean angle and right hip joint angle between two motions. But the lean angle of Croise´ tend to be larger than that of A la seconde and the right hip joint angle of Croise´ tend to be larger than that of A la seconde. The right knee joint angle of Croise´ was larger than that of A la seconde at LS1 which proved to be significant difference between two motions. At other factors, there was no significant difference, but the right knee joint angle of A la seconde tend to be larger than that of Croise´. 5. There was significant difference between two motion at all factors on the height of c.o.g.. The height of c.o.g. of Croise´ tend to be higher than that of A la seconde at LS1 and at LS2. Besides, the height of c.o.g. of A la seconde tend to be higher than that of Croise´ at LB1 and at LB2.

The use of dental implants has increased tremendously in recent years and is expected to increase even more in the future. The successful outcome of any implant procedure is surely dependent on interrelationship of the various components of an equation that includes biocompatibility of implant material, macroscopic and microscopic nature of the implant surface, the status of implant bed, surgical technique, undisturbed healing phase and subsequent prosthetic design and long-term loading phase. The purpose of this study was to clarify the effects of adrenalectomy on the osseointegration of pure titanium implants. Seventy rats, 11 weeks of age, were divided into two groups : an adrenalectomized group and a control group. Titanium screw implant(diameter, 2.0mm ; length, 3.5mm) was placed into left tibia of 70 rats, 35 in control group and 35 in the experimental group. The rats were sacrificed at different time interval (1, 2, 3, 4, 6, 8, and 12 weeks after implantation) for histopathologic observation, histomorphometric analysis and immunohistochemistry with fibronectin and CD44 antibody. The results obtained from this study were as follows : 1.Histopathogically, findings, newly formed bone was seen at 3 weeks control group and became lamellar bone at 12 weeks. At 6 weeks, lipocytes were observed in bone marrow space. Thickness of regenerated trabecular bone increased till 6 weeks after then, that decreased gradually. 2.By histomorphometric analysis, marrow bone density and contact ratio of marrow bone to implant decreased significantly from 8 to 12 weeks in experimental group compared to control group and also total bone to implant contact ratio decreased significantly from 4 to 12 weeks in experimental group compared to control group. 3.Fibronectin immunoreactivity was very strong at 3 and 4 weeks control group. And after that reduced gradually. But it was continuously strong from 1 to 12 weeks experimental group. 4.CD44 immunoreactivity was very strong in the newly formed osteoblasts at 3 and 4 weeks control group. But it reacted minimally later. However, it reacted continuously strong from 3 to 12 weeks experimental group. From these results, bone to implant contact ratio decreased gradually from 4 weeks in adrenalectomized group compared to control group. CD44 and fibronectin immunoreactivities were strong at all times in adrenalectomized rats. Therefore, it could be stated that immature bone remained continuously for a long time and not readily proceeded into mature status.

Amblyopia is poor vision without anatomic abnormality in the eye and can not be improved by lenses. It usually occurs in one eye as a consequence of visual deprivation during the critical period, but has relative good prognosis by early diagnosis and treatment. Conventional evaluation methods are difficult to apply in infants and preverbal aged children because of poor cooperation. The purpose of the present study is to assess the usefulness of visual evoked potentials in the diagnosis of amblyopia. Visual evoked potentials were measured by reversing checkerboard and/or LED goggles stimulation in thirty-nine amblyopic patients and twenty control subjects. The latencies are not different between normal and amblyopic group and also intereye comparison. But amplitude is significant different between two groups by pattern reversal and LED goggle stimulation. But the sensitivity is higher by pattern reversal stimulation. And comparison of amplitude difference or amplitude ratio between the eye are more superior methods, especially pattern reversal stimulation. We think visual evoked potential study can be applied screening test of amblyopic children and identifying emblyopic eye.

본 연구에서는 1200℃의 저온에서 침상형 뮬라이트를 합성하고, 이러한 침상형 뮬라이트를 생성하는 메카니즘을 관찰함과 동시에 메카니즘을 활용한 제어된 미세구조를 가진 뮬라이트를 합성하고자 하였다. Al원으로 사용되는 원료로서는 Al(OH)_3를 사용한 경우가 Al_2O_3를 사용한 결과보다 더욱 발달된 휘스커상의 뮬라이트를 얻을 수 있었다. 각 온도구간에서 열처리한 시편은 미세구조 관찰과 상분석을 통하여 플루오르토파즈와 휘스커상의 뮬라이트의 생성을 관찰하였으며, 토파즈상을 거쳐간 휘스커 뮬라이트의 생성은 하나의 토파즈 상에서 여러 방향으로 휘스커상의 뮬라이트가 성장되는 것을 관찰할 수 있었다. 1200℃에서 생성된 휘스커상의 뮬라이트는 [001] 방향으로 성장하였으며, (110)면의 면간거리는 5.34Å이었다. 과량의 Al(OH)_3를 참가하였을 경우 기존의 8:7:4 원료조합보다 11:7:4의 경우에 조대한 단일상의 휘스커 뮬라이트를 관찰할 수 있었으나, 그 이상의 Al(OH)_3의 첨가는 미반응 Al_2O_3로 인하여 단일상의 뮬라이트를 얻지 못하였다. Whiskered mullites were synthesized at relatively low temperature of 1200℃, and mullite forming mechanism was studied in this experiment. Al(OH)_3 as a raw materials was better in getting whiskered mullite than Al_2O_3. Microstructure and phase analysis were done for the specimens heat treated at various temperatures. It was found that the synthesized mullite had grown to [001] direction, and that the distance of (110) plane was 5.34Å. Al(OH)_3 addition resulted in larger mullite whisker than normal 8:7:4 ratio, but excessive Al(OH)_3 didn't affect the growth of mullite whisker.

Background: Cholestatic hepatitis is failure of bile to reach the duodenum with hepatocellular damage and no demonstrable obstruction of the major bile ducts. The prognosis is usually good with recovery in less than 4 weeks after withdrawal of the offending drug. However, a prolonged course lasting over 3 months is possible and, in rare cases, progression to ductopenia with development of a vanishing bile duct syndrome occurs. A differential diagnosis with other causes of Chronic liver disease is needed. Materials and Methods: From January 1991 through Jaunary 2000, 14 patients diagnosed as cholestatic hepatitis by liver biopsy were inclouded. The possible causative drug, clinical features, laboatory findings, and progression of cholestatic hepatitis were evaluated. The semiquantitative study of liver lesions was performed by two independent observers. Results: Causes of cholestatic hepatitis are 5 cases of oriental medicine, 3 cases of anti-tuberculosis medication, 1 case of ticlopidine and antibiotics and 4 cases of unknown causes. The clinical features of cholestatic hepatitis were jaundice, itching, urine color change, and general weakness. During 6 to 30 months, LFT of 5 patients showed prolonged elevation. Elevated total cholesterol ≥250 mg/dL in 6 patients, pheripheral blood eosinophilia in 5 patients, auto-antibody positive in 6 patients were observed respectively. The biopsies showed intralobular bilirubinostasis with a mixed portal inflammatory infiltration. Conclusion: In cholestatic hepatitis. durations of abnormal LFT are variable regardless of causative drugs. If cholestatic hepatitis progresses toward chronic course, viral hepatitis, primary biliary cirrhosis, and autoimmune hepatitis should be differentially diagnosed and sequential liver biopsies are needed.

To understand clinical characteristics of children with cerebral palsy, ninety three children who were diagnosed to have cerebral palsy in the Department of Rehabilitation Medicine, Chungnam National University Hospital were studied retrospectively. Their medical records were reviewed to see the types of cerebral palsy, distribution of paralysis, possible cause of cerebral palsy, history of seizure, result of brain imaging studies, such as Computerized Tomography (CT), Magnetic Resonance Imaging (MRI), Electroencephalography (EEG), and Auditory Evoked Potential (AEP) study. The results were as follows : 1) They were sixty-four boys (68.8%) and twenty-nine girls (31.2%) with ages ranging from six months to sixteen years, three months (mean : 3 years 11 months) at initial visit and mean duration of follow up was two years, eight months. 2) The most common type of cerebral palsy was spastic (82.7%) followed by mixed, athetoid, ataxic and rigidity types listed in the order of frequency. 3) Topographic distribution of spastic paralysis was led by diplegia (55.8%) followed by tetraplegia (27.3%), hemiplegia (14,3%), and monoplegia (2.6%).. 4) Prematurity and low birth weight were the leading possible causes for cerebral palsy. 5) Incidence of seizure was 23.6% among these children. 6) History of seizure was not directly correlated with abnormal findings of brain imaging, EEG, or AEP, and clinical correlation is recommended. 7) Forty-nine children (52.7 %) were under regular treatment or special education programs provided locally. Problems such as lack of treatment facilities, financial burden, insufficient treatment time, and unsatisfactory treatment, etc. were noted. With the results above, a locally available, more comprehensive management program is highly recommended to provide the children with cerebral palsy the early diagnosis, appropriate, timely intervention, regular treatment, and special education that are needed. Furthermore, ways to prevent prematurity and low birth weight infant should be sought as they are major risk factors for cerebral palsy.

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.
