이 글은 KBS 이산가족찾기(1983)를 재현한 문학작품과 영화 〈길소뜸〉(1985)을 비교하며, 컬러 TV와 전국 실시간 생중계 등 1980년대 한국 TV 방송 테크놀로지의 발전이 공동체를 감각하는 방식에 야기한 변화를 규명하고자 했다. 당시 이산가족찾기가 대중사회에 불러일으킨 충격은 무엇보다도 전 국민이 텔레비전을 통해 실시간으로 연결되고 있다는 ‘동시성’의 감각에서 비롯된 것이었다. 또한 이러한 동시성은 시청자들이 생방송 현장에 참여하고 있다는 감각을 파생시킨다. 텔레비주얼 이미지가 제공하는 동시성과 참여성은 공동체를 재현하는 예술의 영역에서도 적지 않은 충격을 전달했다. 이산가족찾기 이후 한국문단에서는 ‘이산문학’에 관한 논의가 시작되었지만, 작가들은 픽션의 한계를 체감하는 가운데 이전과 다른 방식으로 이산 문제를 소설화해야 한다는 문제와 직면했다. 특히 박완서의 「재이산」(1984) 같은 사례는 공동의 기억을 복원하거나 보편적 시점으로 공동체를 부감하는 것이 더 이상 가능하지 않음을 암시한다. 한편, ‘차가운 리얼리즘’을 보여주는 영화 〈길소뜸〉은 텔레비전 미학을 영화 미학과 결합시킨 사례로서 주목된다. 영화는 미디어 테크놀로지를 통해 개인과 개인이 빠른 속도로 연결되고 있는 상황에서, 역설적으로 공동체가 균질한 공간과 신체로 이루어져 있지 않다는 사실이 잘 드러난다는 점을 포착한다. 이들 작품에서 나타나는바 이산가족찾기는 물리적으로 구현된 동시성 속에서 공동체의 성원들이 각자를 명백한 타자로서 목격하게 된 사건이기도 했다. 이러한 사실은 공동체라는 개념을 혈연적 동질성을 공유하는 집단이 아니라, 동시성만을 공유하는 이질적인 신체들의 집합으로서 생각하게 해준다. This article compares the literary works that represented Finding Dispersed Families(1983) with the movie Kilsodeum(1985), and aims to clarify the changes that the development of Korean TV broadcasting technology in the 1980s, including color TV and live broadcasting nationwide, caused in the way the public sensed the community. At that time, the shock that Finding Dispersed Families caused to the public was, first of all, from the sense of simultaneity that the entire people were connected in real time through television. This simultaneity also derives the sense that viewers are participating in the live broadcast. The synchronicity and participation provided by the televisual image delivered a considerable impact even in the realm of art representing community. After the search for separated families, discussions on “Dispersed Families Literature” began in Korean literary circles, but writers faced the problem of novelizing the issue of separation in a different way than before, while feeling the limitations of fiction. In particular, examples such as Park Wan-seo’s Re-separation(1984) suggest that it is no longer possible to restore common memories or to overlook the community from an omniscient point of view. Meanwhile, Kilsodeum, a film that shows ‘Cold Realism’, is drawing attention as an example of combining the logic of televisual images with film aesthetics. This film shows that, paradoxically, the fact that the community does not consist of a homogeneous space and body is clearly revealed in a situation where individuals are connected at a rapid pace through media technology. As seen in these works, Finding Dispersed Families was also an event in which members of the community witnessed each one as a clear other in the physically embodied simultaneity. This fact makes us think of the concept of community as a group of heterogeneous bodies that share only synchronicity, not a group that shares kinship homogeneity.

Purpose : We want to identify the appearance of the buccolingual root dilaceration teeth in the panoramic views and specify the characteristics of these teeth. Materials and Methods : One thousand-six patients were examined on the basis of both panoramic and CT image criteria. We diagnosed and excluded certain teeth from the samples; both prosthodontic or pathologic lesion appearing teeth and mesiodistally dilacerated ones. We meticulously discerned buccolingually dilacerated teeth in the CT images and total 48 samples were selected. The degree of severity in dilaceration was standardized by 2 types of criteria. The samples were differentiated into 3 groups and again categorized into six types showing from the panoramic views: irregular view on the root apex area, clear blunt on the root tip, stepping on root tip, double lamina dura or double tip, arrow-target shaped root, bull's eye, normal view. Results : The types of teeth selected from total 48 buccolingual root dilaceration samples were mandibular first and second molar, premolars, canines, and lateral incisors. The direction of dilaceration was an even percentage to each buccal and lingual side for most selected teeth, however, that of both canines and lateral incisors were directed in almost a buccal side. In the panoramic views, the root types of the buccolingually dilacerated teeth were irregular view on the root apex area, clear blunt on the root tip, stepping on root tip and normal types were almost always normal view. The more severity in dilareated degree, the more chances of observation in the panoramic views were clear blunt on the root tip and stepping on root tip. Conclusion : As observed in the shape of stepping on root tip or double lamina dura in the panoramic views, there can be much more probability to diagnose as a buccolingually dilacerated root.

Purpose : The research was performed to predict the three dimensional relationship between the impacted mesiodens and the maxillary central incisors and the proximity with the anatomic structures by comparing their panoramic images with the CT images. Materials and Methods : Among the patients visiting Seoul National University Dental Hospital from April 2003 to July 2007, those with mesiodens were selected (154 mesiodens of 120 patients). The numbers, shapes, orientation and positional relationship of mesiodens with maxillary central incisors were investigated in the panoramic images. The proximity with the anatomical structures and complications were investigated in the CT images as well. Results : The sex ratio (M : F) was 2.28 : 1 and the mean number of mesiodens per one patient was 1.28. Conical shape was 84.4% and inverted orientation was 51.9%. There were more cases of anatomical structures encroachment, especially on the nasal floor and nasopalatine duct, when the mesiodens was not superimposed with the central incisor. There were, however, many cases of the nasopalatine duct encroachment when the mesiodens was superimpoised with the apical 1/3 of central incisor (52.6%). Delayed eruption (55.6%), crown rotation (66.7%) and crown resorption (100%) were observed when the mesiodens was superimposed with the crown of the central incisor. Conclusion : It is possible to predict three dimensional relationship between the impacted mesiodens and the maxillary central incisors in the panoramic images, but more details should be confirmed by the CT images when necessary.

The condylar fractures were accounted for 18-35.5% of mandibular fractures. They were attempted to classify with various methods in the previous clinical study. This study was based on the clinical charts and X-ray films, were pertained to the 163 patients who had the condylar fractures. And condylar fractures were classified with respect to 1) the level of the fracture 2) dislocation at the fracture level 3) position of the condylar head against the articular fossa. Then, the results were verified in regard to the ages, causes and other mandibular fractures to find the correlating factors. The results were as follows 1. The most common trauma, associated with condylar fractures was fall injury and it is especially true in children. 2. While the head and neck fractures showed a tendency to associate with fall injury and to occur in children, the subcondylar fractures were associated with blow injury and occurred in adults. 3. The head and neck fractures exhibited a tendency that fractured head was dislocated and fracture edge was overrided at the medial side. In the subcondylar fractures many cases were preserved the normal condylar position and had a tendency to override laterally. 4. The displacement of condyle against the articular fossa was related to the state of override at the fracture level. The override at the fracture level was related to trauma and location of fracture. 5. Most of the concomitant fractures were occurred at the symphysis, occurred in adults and were related to the subcondylar fractures.

Purpose : The purpose of this study was to evaluate the morphologic features of posterior edentulous mandible for Korean patients using cross-sectional CT images. Materials and Methods : Computed tomographic cross-sectional views taken in 2004 and 2005 at Seoul National University Dental Hospital were analyzed by an oral and maxillofacial radiologist. Four indices were measured to meet the purpose of this study: 1) the horizontal distance between the alveolar crest and mandibular canal (Type), 2) the angle of the mandibular long axis (Angle), 3) the bucco-lingual location of mandibular canal, and 4) the depth of the submandibular fossa. The averages and standard deviations of the measurements were compared according to the location (the first and second molar area) and sex of the patients. Results : Statistically significant difference was found in Type, Angle, and submandibular fossa depth between the first and second molar area (P<0.05). However, there was no significant difference between men and women in any of the measured indices. Most of the mandibular canals were located in lingual side of posterior mandible. Conclusion : More care should be taken when an implant is installed on the mandibular second molar area.
