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 : During seasonal influenza epidemics and previous pandemics, pregnant women have been at increased risk for complications related to influenza infection. Although influenza vaccination has been widely recommended to pregnant women and immunocompromised hosts, the vaccination rate is presumed to be low in pregnant women. This study was aimed to evaluate the vaccination rate and factors associated with Influenza vaccination among pregnant women, who are at high risk for developing complications from the influenza. Materials and Methods : This study was carried out by telephone survey from April, 2007 to August, 2007. Women who were in their second trimester of pregnancy or above,- during October, 2006 and February, 2007, the recommended vaccination period, and had given birth at Inha University Hospital were selected as the study population. Immunization status, general understanding, and factors associated with vaccination were evaluated. Results : Among a total of 506 eligible pregnant women, 227 (44.8%) responded to the questionnaires. The influenza vaccination rate among the pregnant women was only 4% (9/227). Major reasons for not receiving vaccination were first, not awaring the necessity of immunization during pregnancy (48.5%, 110/227) and second, misunderstanding that it is prohibited during pregnancy (36.1%, 82/227). The major factors that influenced the compliance of vaccination were correct understanding and doctor's recommendation on the influenza immunization during pregnancy. Conclusions : The influenza vaccine coverage on pregnant women was very low and the awareness of influenza vaccination during pregnancy in general was inaccurate. Shift in perception is required and this can be achieved by educating the pregnant women on the safety and efficacy of vaccination. In addition, doctors' active encouragement to vaccination is highly recommended.

A 10-year old male Pomerarian was presented with about a ten day history of stridor and severe paroxysmal honkinglike coughing which were aggravated with excitement and exercise. Auscultation revealed prominent inspiratory and expiratory crackles and wheezes over the caudal cervical trachea which were heard equally over both side of the chest, and a hemogram showed mild leucocytosis with mild dehydration. On the lateral radiographs of the neck and thorax, the cervical trachea was displaced ventrally by the air trapped between fascial planes of the cervical area near the thoracic inlet. It also revealed a marked narrowing of the tracheal lumen extending from the level of the fifth cervical to the second thoracic vertebra, and the lung field was judged to be within normal limits. There was no evidence of pneumomediastinum. A diagnosis of segmental tracheal stenosis was made. The emphysema of the retrotracheal area was thought to be a traumatic origin. The dog was treated successfully with strict cage confinement for a week. The tracheal stenosis caused by mild emphysema between the soft tissue of the cirvical area or mediastinum in the dog is very rare.

유구치 치근분지부 병소의 치수절제술과 소파술에 의한 골재생

유구치의 깊은 우식은 치수병소을 유발하고 이를 조기에 치료하지 않을 경우에는 치수강저의 수많은 부근관을 통하여 치근분지부 병소로 이어진다. 지금까지 대부분의 교과서나 문헌에서는 이와 같은 경우를 발치의 적응증으로 기술하여 왔고 임상에서도 상례적으로 발치를 흔히 시행하였다. 그러나 유구치의 조기 상실은 수많은 부작용을 낳는 것이 필연적이다. 어린이의 골재생 능력이 우수하며, 치수강저와 치근분지부를 잇는 많은 부근관이 있음을 생각해 볼 때 유구치 치수 내의 감염원을 치수절제술로 제거하고, 이미 발생한 치근분지부 병소에 대해서는 소파술을 시행한다면 치근분지부 골조직의 신속한 재생이 가능하지 않을까하는 의문이 제기되었다. 본 중례는 3~6세 어린이에서 유구치 치근분지부 방사선 투과상이 2~4mm 정도의 깊이를 보이는 비교적 경미한 수준이면서, 연조직 누공을 보이는 10개 중례를 선별하여 치수절제술과 치근분지부 소파술을 시행한 결과, 모두에서 방사선적으로 골재생이 관찰되었다. 이를 통하여 유구치 치근분지부 병소나 누공을 보이는 모든 경우가 발치의 적응증은 아니며, 이 방법이 치근분지부 병소를 가진 유구치를 잔존시킬 수 있는 하나의 대안이 될 수 있음을 알 수 있었다. 그러나 이 방법이 객관적인 타당성을 얻기 위해서는, 병소의 크기와 진행정도, 계승 영구치의 성숙도, 환아의 연령 등 적응증에 대한 보다 심층적인 검토와 연구가 필요할 것으로 사료되었다. Deep caries in primary molars without early intervention frequently induce a pulpal disease and consequent furcation lesion with fistulous openings. Up to now, majority of the textbooks on pediatric dentistry and literatures have described that extraction of the inflicted teeth is indicated for these cases and in reality these teeth have usually been extracted in the dental clinics. However, when we recognize the excellent capacity of bone regeneration in children and the presence of numerous accessory canals at furcation areas, the removal of infection source in pulp by pulpectomy and inflammatory granulation tissues at furcation areas by furcal curettage might open the possibility of rapid healing at the furcation region. In this report. 10 cases of primary molars in 3 to 6-year-old children with fistulous openings and furcation lesions in moderate size of 2 to 4mm in depth radiolucency at furcation lesion have been chosen. After pulpectomy and furcal curettage, evident bone regeneration was detected rediographically in all cases. Through the cases, we came to realize that all the cases previously described are not the indications of extraction and this approach could make many cases with pulp and furca combined lesions survive and remain healthy in the children's dental arches. However, in order for this approach to acquire objective appropriateness. it is thought that more scrupulous evaluation is desirable on the various factors regarding the indication such as the extent of furcation, absorption status of teeth, amount of covering bone on succeeding teeth and so on.

Purpose : This study was to evaluate the beam quality of intraoral X-ray equipments used at Yonsei University Dental Hospital (YUDH) using the half value layer (HVL) and the characteristic curve of intraoral standard X-ray film. Materials and Methods : The study was done using the intraoral X-ray equipments used at each clinical department at YUDH. Aluminum filter was used to determine the HVL. Intraoral standard film was used to get the characteristic curve of each intraoral X-ray equipment. Results : Most of the HVLs of intraoral X-ray equipments were higher than the least recommended thickness, but the REX 601 model used at the operative dentistry department and the X-707 model used at the pediatric dentistry department had HVLs lower than the recommended thickness. The slopes of the characteristic curves of films taken using the PANPAS 601 model and REX 601 model at operative dentistry department, the X-705 model of prosthodontic dentistry department, and the REX601 model at the student clinic were relatively low. Conclusion : HVL and the characteristic curve of X-ray film can be used to evaluate the beam quality of intraoral X-ray equipment. In order to get the best X-ray films with the least radiation exposure to patients and best diagnostic information in clinical dentistry, X-ray equipment should be managed in the planned and organized fashion.

단 1차형 영구자석 선형 동기전동기의 디텐트력 저감 연구

연승환,이종진,함승진,고창섭 충북대학교 컴퓨터정보통신 연구소 2006 컴퓨터정보통신연구 Vol.14 No.1

최근 영구자석 선형 동기 전동기 (PMSLM)는 이송 장치로써 많은 분야에 사용되고 있다. 영구자석 선형 동기 전동기는 구조적으로 간단하며 고속화 고추력화 등의 많은 장점을 가지고 있다. 그러나 단 1차형 영구자석 선형 동기 전동기는 매우 큰 디텐트력을 지니고 있어 추력 맥동의 원인이 되며, 이는 소음과 진동을 발생시킨다. 단 1차형 영구자석 선형 동기 전동기의 디텐트력은 전기자 내부의 치와 영구자석 사이에 작용하는 힘과 전기자 양 단부와 영구자석 사이에서 작용하는 힘의 합으로 표현된다. 본 논문에서는 코깅력을 줄이기 위한 방법으로 영구자석의 극 수와 전기자의 슬롯 수의 비를 변경한 새로운 구조의 단 1차형 영구자석 선형 동기 전동기(PMLSM)을 제안하였고, 단부력을 줄이기 위하여 전기자 양 단부에 전기자 길이 조정법과 챔퍼링 법을 사용하였다. Recently Permanent Magnet Linear Synchronous Motors(PMLSMs) are widely being used for many linear transportation applications. The PMLSMs have many advantages such as simple structure, high speed and thrust force. However, especially in short primary type PMLSM, the PMLSMs have very large detent force, which makes the thrust force ripple and undesired vibration and noise. The detent force in PMLSMs is composed of two forces. The first is the cogging force which comes from the interaction between the permanent magnets and interior teeth of the stator, and the second is the end effect force which acts on the exterior teeth of the stator by the permanent magnets. This paper presents a new configuration of a short primary type PMLSM for cogging force reduction by changing the ratio of the numbers of winding slots and permanent magnet poles. The end effect force is also minimized by optimizing the stator length and chamfering the shape of the exterior teeth of the stator.

A bioequivalence of Melax capsules (Chong Kun Dang Pharm., Korea) and Mobic™ capsules (Boehringer Ingelheim Korea) was evaluated according to the guideline of Korea Food and Drug Administration (KFDA). Single 15 mg dose of meloxicam of each medicine was administered orally to 24 healthy male volunteers. This study was performed in a 2 x 2 crossover design. Concentrations of meloxicam in human plasma were monitored by a high-performance liquid chromatography. AUC, (the area under the plasma concentration-time curve from time zero to 72 hr) was calculated by the linear trapezoidal rule method. C_(max) (maximum plasma drug concentration) and T_(max) (time to reach Cma,.) were compiled from the plasma concentration-time data. Analysis of variance was performed using logarithmically transformed AUC, and C_(max). No significant sequence effect was found for all of the bioavailability parameters. The 90% confidence intervals of the AUCt ratio and the C_(max) ratio for Melax™/Mobic™ were 0.95 - 1.04 and 0.98 - 1.14, respectively. This study demonstrated a bioequivalence of Melax™ and Mobic™ with respect to the rate and extent of absorption.

Objectives Theory of mind (ToM) is the ability to conceptualize other people's mental states in order to explain their behavior. This study compared the ToM ability of schizophrenia patients, their first-degree biological relatives, and healthy controls. Methods ToM animation test was administered to schizophrenia patients (N=28), their healthy first-degree relatives (N=26), and healthy controls (N=28). The Korean version of schizotypal personality questionnaire (SPQ) was used to assess the schizotypal personality trait of all three groups. Results Schizophrenia patients and their first-degree relatives showed decreased accuracy on ToM animation test compared to healthy controls [F(2,78)=29.75, p<.001]. Additionally, first-degree relatives performed worse than the control group and better than schizophrenia patients. First-de-gree relatives had similar SPQ scores compared to healthy controls but showed decreased ToM accuracy compared to healthy controls. Conclusion ToM deficits in schizophrenia patients are apparent. The ToM deficit in first-degree relatives of schizophrenia patients raises the possibility that ToM deficit may be a endophenotype for schizophrenia pathology.
