The pusrpose of this study was to evaluate an effect of change on head posture initial occlusal contacts with measuring the distances between initial occlusal contacts and maximum intercuspal position at different head posture in TMDs patient. For this study, 24 patients from age 13 to 36 were selected, they were examined health history taken, patients who have sign and symptoms of TMDs were examine before the study. For the normal group, 21 adults from age 23 to 25 were selected. They have normal or classⅠmolar relationship, and have no symptoms of TMJ or masticatory muscles, and some of them had restorations less than 3 areas on each tooth, and have no other prosthetic restorations. Difference on distance between initial occlusal contact and maximum intercuspal position with mandibular kinesiograph(MKG??)(K6 diagnostic system, Myo-tronic Inc., U.S.A.) in upright, supine, 45˚extension, 30˚flexion position of the head were measured. The Frankfort horizontal plane was used as a reference plane. The results were as follows 1. There were significant differences between initial occlusal contacts of the normal and patient group on upright position and 30˚ flexion of the head(p<0.05, p<0.01). 2. The positions of the initial occlusal contacts have a tendency to place anterior and inferior to maximal intercuspal position in upright position and 30˚ flexion of the head as well as posterior and inferior in supine position and 45˚ extension of the head in the noraml and patient groups. 3. There were significant differences among the initial occlusal contacts between upright and supine position ; upright and 45˚ extension of the head(p<0.05) ; supine position and 30˚ flexion of the head, and 30˚ flexion and 45˚ extension of the head in the patient group(p<0.01). The results have shown that after treatment on the supine position, it may be necessary to check occlusal contact on the upright position as well as flexion of the head. It may need careful adjustment in occlusal condition on upright position of TMDs patient.

정원후,김성부,장기용,손진욱,박철수 大韓神經精神醫學會 1997 신경정신의학 Vol.36 No.4

저자들은 1996년 5월 1일부터 1996년 7월 15일까지 부산·경남·대구 소재의 대형정신병원과 종합병원에 입원해 있는 여성 알코올리즘을 대상으로 하고, 또한 같은 기간에 국립부곡정신병원에 입원한 남성 알코올리즘을 비교군으로 해서 사회인구학적 특성, 음주양상, 음주와 관련된 문제점, 성격 및 정신병리등을 비교하여 남녀 알코올리즘에서의 원인과 임상적 특성에서의 차이점을 알고자해서 본 연구를 하게 되었다. 저자들이 작성한 반구조화된 설문지, MAST(Michigan alcoholism screening test). Zung의 SAS(Self-rating anxiety scale)과 SDS(Self-rating depression scale). MMPI(Minnesota Multiphasic Personality Inventory), SCL-90-R(Symptom checklist-90-revision) 및 EPQ(Eysenck personality questionnaire)등의 검사도구를 이용하였고, 그 결과를 독립표본 t-test(independent-samples t-test)와 χ²-test로 검정하여 다음과 같은 결론을 얻었다. 1) 여성 알코올리즘에서 남성 알코올리즘보다 더 낮은 교육 수준을 보였으며 초등학교수준 이하가 52.4%를 차지하였다. 반면에 남성 알코올리즘에서는 중학교·고등학교 수준이 76.7%였다.(p〈0.01). 2) 여성 알코올리즘에서 형제들 중에서 더 낮은 서열을 보였으며 세째딸이 1/3로 가장 많았고 다음이 외동딸로써 23.8%를 차지하였다. 반면 남성 알코올리즘에서는 장남이 46.7%였다.(p〈0.01). 3) 여성 알코올리즘이 사회경제적 수준에서 더 낮았다(p〈0,01). 4) 여성 알코올리즘의 음주시작동기는 대인관계를 위한 사교목적, 심리적 갈등이나 다른 정신적인 문제, 가족들과의 갈등 등이 비슷하게 많았다. 그러나 남성 알코올리즘에서는 대인관계를 위한 사교목적으로 음주하는 경우가 절대적으로 많았다.(p〈0.05). 5) 처음으로 음주를 시작한 연령은 여성 알코올리즘보다는 남성 알코올리즘에서 유의하게 더 어린 연령에서 시작하였다.(p〈0.001). 6) 1일 평균 음주량은 여성 알코올리즘에서 유의하게 더 적었다.(p〈0.01). 7) 금단증상경험, 알코올성 신체장애 및 음주로 인한 법적 처벌경험도 남성 알코올리즘보다는 여성 알코올리즘에서 유의하게 더 낮았다.(p〈0.05). 8) SCL-90-R에서 PSY척도에서 유의하게 여성 알코올리즘군에서 더 높았고, EPQ에서는 L척도에서 유의하게 여성 알코올리즘이 더 높았다(p〈0.05). 결론적으로 본 연구는 심리적 요인과 사회적 요인이 남녀 알코올리즘간에서 많은 차이가 있는 것을 알 수 있었으며, 여성 알코올리즘의 원인에는 심리적 또는 사회인구학적 요인이 더 밀접하게 연관이 되어 있음을 알 수 있었다. Objective : This study was designed to compare the characteristics of demographic data, clinical features, and personality in male and female alcoholics and to identify the clinically meaningful differences in the etiologies and the clinical features between the two groups. Methods : The study group was composed of 30 males and 21 females who were recruited into the impatient treatment. The researchers used self-reporting questionnaire composed of demographic data and drinking patterns, Michigan alcoholism screening test(MAST), self-rating anxiety scale(SAS) and self-rating depression scale(SDS) of Zung, Minnesota Multiphasic Personality Inventory(MMPI), symptom Checklist-90-revision(SCL-90-R), and Eysenck personality questionnaire(EPQ). The differences between the two groups were tested by chi-square test and independent-sample t-test. Result : 1) Education level of the female alcoholics was significantly less than that of male alcoholics(p〈0.05) and the birth order the female alcoholics was significantly higher than that of male alcoholics(p〈0.05). 2) The level of socioeconomic status of female alcoholics was significantly lower than that of male alcoholics(p〈0.01). 3) The initial motivations of female alcoholics were mainly due to social, psychological, and intrafamilial problems while those of male alcoholics were due to social problems. There were significant difference between the two groups(p〈0.05). 4) The onset of initial drinking in female alcoholics was significantly earlier than that of male alcoholics(p〈0.001). 5) The average amount of daily drinking in female alcoholics was significantly less than that of male alcoholics(p〈0.01). 6) Withdrawal symptoms, physical disorder, and social or legal problems induced by alcohol drinking in female alcoholics were significantly less than those of male alcoholics(p〈0.05). 7) The mean scores of PSY scale of SCL90R and of L scale of EPQ in female alcoholics were significantly higher than those of male alcoholics(p〈0.05). Conclusion : Demographic and psychosocial factors differed to a significant degree between male and female alcoholism. We suggest that these factors are more important in female alcoholism than in male one in the etiologies and the clinical features. These differences are due to more complex factors rather than simple ones, thus the further evaluations are needed to elucidate the differences in the etiologies between male and female alcoholism.

공석원,송인창,한문희,장기현,류인균,권준수 대한신경정신의학회 2000 신경정신의학 Vol.39 No.6

연구 목적 : 강박증의 생물학적 원인으로 전두엽-선조체 회로의 이상이 알려져 있다. 그러나 형태학적 뇌영상을 이용한 기존의 연구는 전두엽과 미상핵의 용적 변화에 대한 일관된 결과가 없었다. 따라서 본 연구에서는 선형변환을 통한 반자동화된 방법을 이용하여 뇌의 각부위에 대한 형태학적 연구를 위하여 시행되었다. 방 법 : DSM-IV의 기준에 의해 진단한 13명의 강박증 환자와 9명의 정상대조군을 대상으로 하였다. 3차원 뇌자기공명영상을 Spoiled gradient-recalled(SPGR)법으로 얻었다. 3차원으로 재구성된 뇌자기공명영상을 Talairach와 Tournoux의 표준화 좌표에 공간적 정위시킨 후 회질과 백직을 반자동화된 방법으로 분리하였다. 죄표에 의거한 뇌엽의 각 부위에 대한 용적 측정을 하고, 미상핵은 수기로 구획한 후 용적측정을 하였다. 전두엽은 Brodman 의 영역에 의거하여 좌표계에 따른 분할을 하여 배외측전두엽, 안와전두엽, 내측전두엽으로 분할 구획하여 용적을 측정하였다. 결 과 : 강박증군에서 전두엽 회질의 용적이 증가되는 경향을 나타내었다. 다른 부위의 회질과 백질 그리고 미상핵의 용적은 차이가 없었다. 편측성에 의한 차이도 없었으며, 임상적 심각도와 상관관계는 관찰되지 않았다. 결 론 : 본 연구에서는 강박증군에서 전두엽의 용적 증가를 관찰할 수 있었으며, 이것은 기존 연구 중 일부에서 전두엽과 미상핵의 용적 감소를 보고했던 것과 차이가 있다. 강박증이 만성화되고 일정기간 이상이지나 구조적 변화가 오기 전까지 오히려 대사와 혈류 증가에 따른 회질 용적 증가가 관찰되는 것이라 생각된다. Objectives: Neurobiological models for obsessive-compulsive disorder(OCD) have consistently Implicated prefrontal-striatal circuits in the pathophysiology of this disorder. But, prior studies have inconsistently found alteration in caudate and frontal lobe volumes in patients with OCD. This study was undertaken in the hope that semi-automated linear transformation methods would elucidate the morphometric differences of various parts of brain between OCD and normal control group. Methods : Thirteen parients meeting the DSM-IV criteria fro OCD, and 9 psychiatrically normal comparison subjects participated in the study. 3-D brain MRIs using Spoiled gradient-recalled(SPGR) sequence were acquired for each subjects. After spatially normalized according to Talairach and Tournoux's coordinates, the gray and white matters were segmented by semi-automated methods using fuzzy algorithm. Each lobal volumes was measured according to Talairach and Tournoux's coordinates, and the region of interests of caudate nuclei was manually traced. The frontal lobe was divided into 3 subregions ; dorsolateral prefrontal cortex, orbital frontal cortex, mesial frontal cortex accoring to the coordinates and Broadman's cytoarchitectonics. Results : Only the volume of left and right frontal gray matter showed a significant difference between OCD and normal subjects. In OCD, the frontal gray matter volume was increased in tendency. There's no difference in laterality and no coorelation with clinical severities. Conclusion : Findings of increased frontal gray matter volumes in patients implicate a structural abnormality of these brain regions in the pathophysiology of OCD. The increased frontl gray matter volumes reflect a epiphenomena due to increased cerebral blood flows and metabolic rates before the structural changes may occur.

광중합기의 광원에 따른 브라켓 전단결합강도 비교

차정열,이기준,박선형,김태원,유형석 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.3

제논 플라즈마 아크 광중합기나 LED 광중합기가 치과영역에 소개된 이후로 기존의 텅스텐 할로겐 광중합기를 사용할 때에 비해 교정장치의 부착시간이 현저하게 줄어들 수 있게 되었다. 제논 플라즈마 아크 광중합기에 대한 중합시간과 전단강도에 대해서는 여러 연구가 있어왔던 반면, LED 광중합기를 이용하여 교정용장치의 부착을 위한 중합시간에 대한 연구는 미진하다. 본 연구의 목적은 LED 광중합기의 중합시간에 따른 결합강도를 플라즈마 아크 광중합기와 비교하여 적절한 브라켓의 부착강도를 얻기 위해 요구되는 중합시간을 알아보는데 있다. 120개의 발치된 사람의 소구치에 컴포짓 레진으로 브라켓을 부착시킨 후 4초, 6초, 8초 동안 플라즈마 아크 광원과 LED 광원으로 각각 중합시켰다. 그 후 결합강도를 만능시험기(Universal Testing Machine)로 계측한 결과, 플라즈마 아크 광중합기에서는 4초 이상에서, LED 광중합기에서는 8초 이상의 중합시간에서 기존의 할로겐 광원을 40초간 노출시켰을 때와 비슷한 전단결합강도를 나타내었다. 플라즈마 아크 광중합기와 LED 광중합기의 중합시간이 접착제 잔류지수(adhesive remnant index) 수치에 대해 영향을 미치지 않았다. With the introduction of the xenon plasma arc curing light and the LED curing light as orthodontic curing lights, the polymerizing time of orthodontic composites has clearly decreased. In contrast to various research cases regarding the polymerization time and bond strength of the xenon plasma arc curing light, not enough research exists on the LED curing light, including the appropriate polymerization time. The objective of this research was to compare the bond strength of the plasma curing light and the LED curing light in regards to the polymerization time. The polymerization time needed to achieve an appropriate adhesion strength of the bracket has also been studied. After applying orthodontic brackets using composite resin onto 120 human premolars, the plasma arc curing light and the LED curing light were used for polymerization for 4, 6, and 8 seconds accordingly. This research proved that the LED curing light provided appropriate bond strength for mounting orthodontic brackets even with short seconds of polymerization. The expensive cost and large size of the device limits the use of the plasma arc curing light, whereas the low cost and easy handling of the LED curing light may lead to greater use in orthodontics.
