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.

Chronic eosinophilic pneumonia(CEP) is a rare disease of unknown etiology characterized by chronic infiltration of the lung with eosinophils. It presents with profound systemic symptoms comprising fever, night sweats, weight loss, dyspnea and blood eosinophilia with nonsegmental air-space consolidation confined to the outer third of the lung, the "photographic negative of pulmonary edema". Histopathologic features of chronic eosinophilic pneumonia are intraalveolar and interstitial infiltrations with eosinophils, histiocytes, giant cells, scattered lymphocytes and plasma cells. Glucocorticoid therapy cause prompt resolution of symptoms as well as disappearans of blood eosinophils, elevated serum Ig E levels and the roentgenographic lesions. Infrequent radiographic findings include nodular infiltrates, consolidations, cavitations, atelectasis and pleural effusions. Deaths from CEP although rare, have been reported, but the majorities of CEP have benign courses and do not need a therapy with ventilator. We report a case of chronic eosinophilic pneumonia, which had a sudden course associated with diffuse pneumonic consolidations on the both lung and bilateral pleural effusion.

Micro end-milling process is applied to fabricate precision mechanical parts cost-effectively. It is a complex and time-consuming job to select optimal cutting conditions with high productivity and quality. To consider the productivity and quality of precision mechanical parts, micro end-mill wear and cutting force characteristics should be studied exactly. In this paper, high speed machining experiments are studied for optimum process design and modeling of cutting parameters in micro ball end-milling processes. Cutting force and wear characteristics under various cutting conditions are investigated through the condition monitoring system and Taguchi method. Mathematical models for the cutting forces are derived from the response surface method. Optimal milling database has been constructed through experimental models.

The purpose of the study was to observe the association between the main colors of school chidlren's drawings of dental treatment situation and their dental anxiety. The subjects of study were 688 school children from 2nd to 4th grade. Caries experience was investigated by oral examination. Questionnaire survey was done regarding children's attitude toward the dentist and dental treatment and their experience of pain and fear during the dental treatment. Colors with high frequency of use were green, blue, yellow, orange, pink, purple, gray, brown, yellow ochre, red, white and black in order. Boys used green and blue, and girls used yellow and orange, more than each other. As the grade increased, white, yellow, and blue increased and brown decreased. Colors with high dental anxiety level were black, brown, red, white, blus, orange, yellow and green, yellow ochre, gray, pink, and purple in order, and the upper four represented 10.5% of the subjects. Children with high decayed teeth rate had a tendency to use colors of high dental anxiety level. Black color had the most obvious association with the pain and fear of dental treatment.

In this paper, we studied on the environment map building for the autonomous mobile robot navigation using the vergence controllable stereo camera system. First of all, distance measurements are necessary to build the environment map. So, we present the distance measurement method using the stereo camera system and a laser pointer. To measure the distance using the stereo camera system, finding the common points in the left and the right images are needed. In this study, we use a laser pointer to solve this problem. Secondly, we present the method how to obtain the 3-dimension position information using 3-D geometric schematic of the stereo camera and the measured distance information. This information is essential to the mobile robot navigation. Finally, we prove the presented method experimentally. An image of a corridor is taken by the stereo camera. The door and pillar in this image are landmarks. Therefore, we find such landmarks in the image and measure the 3-D position information for those landmarks. And the, we construct the environment map for the navigation of the mobile robot.

It has been known that noble metal alloys are one of the most important materials for dental use. In particular, silver base alloys containing copper are most widely used because of their age-hardenability. But their ageing process has not been fully understood. In the present work, the electrical resistivity and hardness change during ageing of dental silver alloys were measured and the ageing process was discussed. Principal results were as follows; (1) The standard compositions of the silver alloys were (50-55wt%) Ag+(28-20wt%) Pd+(10wt%)Cu+(5-12wt%)Au (2) The ageing treatment at 350 to 450℃ for 10 to 60 min should be the optimum condition for age-hardening treatment of these alloys. (3) The electrical resistivity showed a characteristic peak in the early stage of isochronal ageing. This peak will probably correspond to clustering of certain solute atom. (4) The isothermal ageing curves of A, B alloys were like each other in shape. The apparent activation energy for the precipitation process were calculated to be about 39 and 36Kcal/mol, respectively.

Introduction : Chronic hemodialysis patients have been psychological problems because of being compelled to follow a dialysis schedule for a long period of time. Specificially, depression and anxiety are so frequently observed that psychological management is requireed for most hemodialysis patients. Fragnance has been known to have beneficial psychological and physiological effects on human. This study was designed to investigate the psychological effect of aromatherapy on chronic hemodialysis patients. Methods : 40 subjects of this study selected from Je Young-Sung Internal Medicine Clinic in Busan. The experimental group were random assigned to 20 subjects who had visited on Monday,& Wendesday & Friday and received aromatherapy every day for 2 weeks. the control group were random assigned to 20 subjects who had visited on Tuesday & Thursday & Saturday and did not receive any intervention. Experiment had been conducted from July. 7th July 21, 2003 and anxiety by Spilberger's state anxiety scale and depression by Zung's Scale were measured in the course of aromatherapy for both experimental group and control group. A control period consisting of natural hospital smells was established before each test session, and then aromatic test conditions were systematically evaluated for odorless conditions as well as aromatic conditions containing 100% lavender necklace for 2 weeks. Data were analyzed by, frequency, percentage, mean, S.D. χ²- test, t-test. Results : 1) Anxiety scores were not significantly decreased in the experimental group(54.57±13.20) after treatment compared to the control group(49.45±12.41)(t=1.225, p=.228). 2) Depression scores were significantly decreased in the experimental group(43.95±5.63) after treatment compared to the control group(49.65±9.84)(t=-2.367, p=.023). Conclusions : These findings indicate that the aromatherapy may decreased depression. It is suggested that the aromatherapy could be an effective nursing intervention to reduce to depression by chronic hemodialysis patients.
