Purpose : To assess the functional change of salivary gland, recovery of salivary destruction, difference of susceptibility to irradiation between the parotid and sub-mandibular gland, correlation between the xerostomia and excretory rate by irradiation in salivary scan using $^{99m}Tc$-pertechnetate in patients with head and neck cancer. Materials and Methods : We evaluated 19 patients with head and neck cancer who had taken $^{99m}Tc$-pertechnetate salivary gland scan before, during and after radiotherapy. We measured the uptake of radioactivity every 5 minutes for 60 minutes after injection of $^{99m}Tc$-pertechnetate(370MBq). We also evaluated the first excretory function stimulated by 5% citric acid at 30 minutes after injection of $^{99m}Tc$-pertechnetate and then the second excretory function stimulated by 10% citric acid at 45 minutes. Results : The mean uptake curves showed a sharp increase at the 1st week of radiotherapy and then showed a gradual decrease afterwards during radiotherapy. And the mean uptake curves after radiotherapy Persistently decreased on follow up scans without being recovered. The excretory rates decreased gradually as radiation dose increased and were not recovered after radiotherapy. Our study was not satisfactory enough to show the difference of susceptibility to irradiation between the parotid and salivary gland and the correlation between the symptom of xerostomia and the change of the excretory rates. Conclusion : The parotid and submandibular gland scans using $^{99m}Tc$-pertechnetate are useful in the assessment of the functional change of the salivary gland by radiotherapy and predicted the functional change of the salivary gland until 1 year-follow up scan.

It has been reported that skeletal relapse and dental change after mandibular setback do occur not only after intermaxillary fixation(IMF) removal but also during IMF The side effects of skeletal relapse during IMF have clinical importance because they can cause many Postoperative orthodontic Problems. Generally, the Prevention of solid union between segments, compensatory tooth movement, anterior openbite, etc. have been cited as the side effects of jaw displacement. The purpose of this study was to evaluate the skeletal relapse and dental change during IMF. The material consisted of 28 patients who were treated by BSSRO(bilateral sagittal split ramus osteotomy), wire osteosynthesis, IMF for correction of mandibular prognathism. Through cephalometric analysis, the amount and direction of surgical movement, skeletal relapse and dental change during IMF were measured. The correlation between surgical movement and skeletal relapse, between skeletal relapse and dental changes were evaluated. The following conclusions were obtained; 1. Distal segment was repositioned backward and upward, proximal segment showed clockwise rotation during surgery. 2. During ]m, anterior portion of distal segment was displaced backward and posterior portion was displaced upward. Proximal segment was displaced upward with forward movement of p-Go(gonion of proximal segment). Backward surgical movement of p-GO was significantly correlated with forward displacement of p-Go. 3. Overjet and overbite were not changed during IMF. The compensatory tooth movements during IMF were characterized by retroclination of upper incisors md retroclination, extrusion of lower incisors. These compensatory tooth movements had statistically significant correlation with upward displacement of d-Go (gonion of distal segment).

교회음악은 보다 넓은 뜻에서 그리스도교 신앙 안에서 작곡된 모든 음악 곡들을 포함하지만, 전례음악(성음악)은 하느님께 예배를 올리는 식전 즉, 전례를 위해서 작곡된 음악을 뜻합니다. 결과적으로 애초부터 연주회를 목적으로 작곡되었다든지 일반 기도모임이나 혹은 신자 단체의 결속을 위해서 만들어진 노래들은 교회음악에는 들어가지만 성음악은 아닌 셈입니다.

본 연구는, 기존의 나열식 분류체계의 문제점을 극복할 수 있는 GRAIL을 이용하여 두경부의 해부학적 구조물들 및 구강 악안면 영역의 주요 질병들과 관련된 치의학 개념들의 모델을 구축한 뒤, 완성된 치의학 개념 모델이 두경부의 해부학적 구조물들 및 구강 악안면 영역의 주요 질병들을 잘 표현할 수 있는지와 기존의 GRAIL 모델이 지닌 특징에 잘 부합하는지를 평가하고자 시행되었다. 서울대학교 치과병원 내원 환자 중 포괄적인 치과 치료 병력을 지닌 환자 150명의 치과 의무기록을 내용별로 분석하고, 각종 치의학 교과서와 기존의 의학용어 분류체계에서도 모델 구축에 필요한 치의학 용어를 선택하였다. 이들 자료를 바탕으로, GRAIL 모델 구축을 진행하고 구축된 모델을 평가할 수 있는 소프트웨어 프로그램인 'KnoME'에서 치의학 개념 모델을 구축하고 평가하여, 다음과 같은 결론을 얻었다. 1. 환자 150명의 치과 의무기록을 내용별로 분석한 결과, 우선적으로 모델 구축이 필요한 치의학 용어로는, 해부학적 구조물의 경우 치아, 치은, 악관절, 입술, 턱, 혀 등의 순서로 나타났으며, 구강악안면 영역의 병소에서는 치아 우식증, 치주염, 치은염, 악관절 장애, 매복 지치, 치경부 마모 등의 순서로 나타났다. 2. GRAIL을 이용하여 치아, 치주조직, 구강점막조직, 치아 우식증, 치수 및 치근단 병소, 치주질환, 구강점막질환의 모델 구축을 시행한 결과, 치의학 개념간의 다양한 관계가 대다수 잘 표현되었다. 그러나, 구강 악안면 영역의 해부학적 구조물에 대한 공간 정의의 한계성과 구강 악안면 질환의 진행 양상에 있어서 표현의 어려움이 관찰되었다. 이러한 부분은 GRAIL을 치의학 분야에 적용할 때, 극복해야 할 한계로 나타났다. 3. 치의학 개념들에 관한 다양한 질의를 시행한 후 그 응답 내용을 평가한 결과, 완성된 모델 내에서 치의학 개념의 자동적인 분류가 이루어 졌으며, 다양한 목적의 검색이 가능하였다. 이와 같은 사실로 미루어 보아서, 완성된 모델은 기존의 GRAIL 모델의 특성에 잘 부합되는 것으로 생각되었다.

The purpose of this study was to determine whether association exists between temporomandibular joint (TMJ) characteristics in transcranial radiographs and TMJ internal derangement and to evaluate the validity of transcranial radiographs in diagnosis of internal derangement. Transcranial radiographs and magnetic resonance imaging (MRI) of 113 TMJs from 76 subjects were used for this study and all TMJs were classified into 3 groups according to the results of MRI: normal disk position, disk displacement with reduction, and disk displacement without reduction. Transcranial analysis included linear measurement of joint spaces and condylar head angle measurement. To determine any relationship between transcranial measurements according to disk displacement, one-way ANOVA was used. The results showed that condyle-fossa relationship in standard transcranial radiographs had no relationships with disk displacement. And, as disk displacement progressed, condylar angle between head and neck increased significantly. This result can be interpreted that condylar head angle reflects structural hard tissue change according to internal derangement progress. But this is insufficient in the determination of internal derangement. Therefore, although still clinically helpful, the validity of standard transcranial radiographs to diagnose TMJ internal derangement was questioned.

Overall study was carried out for the patients visiting Department of Oral & Maxillofacial Surgery through Emergency Room in Chonnam University Hospital, from Jan. 1, 1992 to Dec. 31, 1996. Result obtained were as follows ; Male predilection was shown, the male to female ratio being 2.5 to 1. The frequently developing age group were the first 3rd and 4th decade and under the age of 9 was followed. The number of patients for emergency was peak in September and October to 11%. About the causes for emergency, traffic accident was the most, and fall down injury and assault were followed. About the injury lists, facial laceration was preceded and the next facial bone fracture and the tooth injury followed. In the facial bone fracture, fracture in the mandible only was the most, and zygomaticomaxillary complex fracture, and mandible-maxilla complex fracture were followed. when the case of the mandible fracture, symphysis, condyle, angle were marked in succession. 57% was predomunatly ranged in the timea of 18 : 00 to 03 : 00 for the emergency. From injury onset to visiting emergency room, the range of 8 hours to 12 hours was predominant. Above results suggest that urgent patients of oral and maxillofacial area were relatively so high that division of oral and maxillofacial surgery should be established immediately.

The purpose of this study was to evaluate the skeletal and dentoalveolar effects and optimal timing for treatment of class II malocclusion with functional appliances in children and adolescents. A group of 30 patients with class II malocclusion were divided into 3 groups according to their use of functional appliance: Twin block, Activator, Fränkel appliance. The group was also divided into 2 groups according to the cervical vertebrae maturation method. Lateral cephalometric radiographs were analyzed pretreatment (T0) and posttreatment (T1). Among the functional appliances, treatment with Twin block and Activator showed significant increase in the length of the mandible (Co-Gn) and the lower anterior facial height (ANS to Me), whereas the overjet and overbite were significantly reduced. Treatment with Fränkel appliance showed significant improvement in the relationship of maxilla and mandible. In addition, if the functional appliance was used during the period of pubertal growth peak, there was a significant increase in mandibular length, improvement in the relationship of maxilla and mandible, labial inclination of lower incisors and decrease in overjet compared to the treatment before pubertal growth peak. Therefore, this study indicates that using functional appliances for patients with class II malocclusion is effective and the optimal timing for using functional appliances is during pubertal growth peak.

The villains in recent films are given interesting roles not only through the actual contents of the story but also by attractive personal characteristics including internal and psychological aspects. The purpose of this paper is to take a deeper look into the image styling process of villain characters. The cases will focus on seven representative Korean films that have attracted over one million audiences as of the year 2000, and the leading and supporting actors within those films. Analysis will be made mainly on the visual image creations of those villains. The visual images are categorized by the make-up, hair-do, clothing and accessories relevant to the psychological personality type of each actor's role and their background based on the given scenarios. The results are as follows: First, villain characters are portrayed as an individual with multiple personalities with regards to psychological, economical, and vocational aspects. Second, fashion trends of the character is an important element to keep pace with the times or to visualize the sense of the times in which the villain exists. Third, a specific point that characterizes the villain's character are expressed through various touches using noticeable accessories, specific colors in make up, hair style, and a certain fashion.
