The present study reports a case of eosinophilic granuloma of the mandibular condyle. Eosinophilic granulomas on the mandibular condyle are very rare, but there are several common clinical and radiographic presentations. The clinical presentations involve swelling on preauricular area, limitation of opening, TMJ pain, etc. The radiographic presentations involve radiolucent lytic condylar lesion with or without pathologic fracture. Sometimes new bone formations are observed. The purpose of the article is to add new cases to the literatures.

본 연구는 전국의 대학교 졸업생들을 모집단으로 확률 표본추출방법에 의해 표집된 대규모 설문조사 자료를 분석함으로써 대학생들이 첫 직장으로 진입하는 과정에 영향을 미치는 요인들을 실증적으로 검토하였다. 분석 결과를 보면, 일반적으로 인적자본으로 거론되는 변수들, 그리고 기회구조를 나타내는 변수들 모두 첫 직장으로의 탈출 확률에 통계적으로 유의한 영향을 미치는 것으로 나타났다. 더욱 중요한 것은 이러한 변수들이 모두 통제되었을 때, 구직과정에 관한 변수들이 첫 직장 진입에 있어 매우 중요한 역할을 한다는 점이다. 즉, 다른 조건이 동일할 때, 좀 더 빨리 구직을 시작하고 다양한 방법을 동원해 직장을 알아보는 것은 첫 직장을 얻는 데 유의하게 긍정적인 효과를 지니며, 특히 좋은 직장의 경우에는 공식적인 방법을 사용해 구직을 하는 것이 효과적인 것으로 나타났다. Analyzing a national probability sample on college graduates, this study aims to empirically examine the factors which are presumed to have effect in obtaining the first job. Our analyses find that factors that measure the supply side of labor and the factors that measure the demand side of labor are both important in obtaining the first job. More importantly, however, we find that controlling for these factors, variables on job search method and job search period are also important in obtaining the first job. This implies that universities can also play a role in increasing their graduates' probability of obtaining the first job by playing a more active role in the process through which the supply and demand side of labor get to meet each other.

구강악안면영역의 3차원 CT 영상 재형성시 역치 및 불투명도에 대한 연구
최문경,이삼선,허경회,이원진,최순철 대한구강악안면방사선학회 2009 Imaging Science in Dentistry Vol.39 No.1
Purpose : This study was designed to determine a proper threshold value and opacity in three-dimensional CT volume rendering of oral and maxillofacial area. Materials and Methods : Three-dimensional CT data obtained from 50 persons who were done orthognatic surgery in department of oral and maxillofacial radiology of Seoul National University retrospectively. 12 volume rendering post-processing protocols of combination of threshold (100HU, 150HU, 221HU, 270HU) and opacity (58%, 80%, 90%) were applied. Five observers independently evaluated image quality using a five-point range scale. The results were analyzed by receiver operating characteristic curves, ANOVA and Kappa value. And three oromaxillofacial surgeons chose the all images that they thought proper clinically in the all of images. Results : Analysis using ROC curves revealed the area under each curve which indicated a diagnostic accuracy. The highest diagnostic accuracy appear with 100HU and 58% opacity. and the lowest diagnostic accuracy appear with 221HU and 58% opacity that are being used protocol in department of oral and maxillofacial radiology of Seoul National University. But, no statistically significant difference was noted between any of the protocols. And the number of proper images clinically that chosen by three oromaxillofacial surgeons is the largest in the cases of protocol 8 (221HU, opacity 80%) and protocol 11 (270HU, opacity 80%) in one after the other. Conclusion : Threshold and opacity in volume rendering can be controled easily and these can be causes of making an diagnostic accuracy. So we need to select proper values of these factors.

The coin charms were first introduced from China into the Koryo Reidn around the early part of 10th century. The charms were, however, only the imitations of the coin charms of China. The special Korean coin charms dated from the fifth year of Sook Dong, the 19th King of the Yi Dynasty when made as samples at the time. The coin charms were used as accessories, ornaments, fortune-telling items, etc. Therefore, the charms weere increasingly in high demand. As there were no clear and definite criteria as to when the coin charms were originally made, the analysis was made according to the patterns and forms of the coin charms. The patterns of coin charms are as follows: (1)Animal-shaped patterns These are the patterns of bats, dragons, deer, turtles, cranes, phoenixes, a pair of fish, butter-files, honey bees, etc. (2)Plant-shaped patterns These are the patterns of lotus flowers, peer flowers, plum blossoms, palmettes, Posangwha(holy image flowers), etc. (3)Ten long-life symbol patterns (4)Figure patterns (5)Chil Bo patterns (6)Geometrical patterns The Yeol ssoe pae seems to be made much later than the ones which were used as accessories. The Yeol ssoe pae was used with the keys attached, however, mainly patronized as ornaments of interior decoration. The Yeol ssoe pae consists of a linkage of several small coin charms, and has the forms of a bag, palmette, a dragon and angular shape. The coin charms pattern which seems to be the oldest, is the round shape with a square inside. Then comes the round one. There follows a round shape with a ring above, and a round shape with a flower inside and a ring above. In case the angular shapes or patterns form the shape of coin charms were included in classification. The older the coin is, the more realistic the expression of the pattern is. The patterns of the later coin charms are less complex and rustic. I general the patterns of coin charms represent the customs, religion, ideas, and hope of the Korean people i the Yi Dynasty. the other side of the coin charms holds the characters or patterns which harmonize with the front or and overall shape of the coin. As the patterns of the coin charms were more various than those of the other Yi Dynasty industrial products and included a variety of expressions concerning every subject, they were considered good materials for the pattern analysis and a survey of coin charms. It is highly expected that some touch of "modernization" based on the above patterns, is added to the industrial products of today and that the analysis can be of help to doing away with some of the "clumsy" patterns of the various products.

Glasser식 학급회의가 초등학생 문제행동의 감소에 미치는 효과
최문경,박재황 한국현실치료학회 2013 현실치료연구 Vol.2 No.1
본 연구의 목적은 Glasser식 학급회의가 초등학생 문제행동의 감소에 미치는 효과를 검증하기 위한 것이다. 본 연구의 대상은 대구광역시 소재 S초등학교 3학년 1학급 31명이다. Glasser식 학급회의는 일 주일에 5번, 1개월 동안, 총 10회, 실시하였다. 문제행동으로는 네 종류의 문제행동, 즉 지각, 신체적 폭력, 따돌림, 말싸움을 선정하였다. Glasser식 학급회의가 시작되기 전까지는 기초선 측정을 하였으며 그 이후에는 처치 후 측정을 실시하였다. 모든 측정은 4가지의 문제행동에 대해 아동 스스로 하교하 기 전에 자기 평가 카드에 기록하도록 하였다. Glasser식 학급회의에 따른 학생의 문제행동 감소에 미 치는 효과를 알아보기 위하여 빈도의 변화 추이를 분석하였다. 연구 결과, Glasser식 학급회의에 참여 한 학생들의 문제행동, 즉 지각, 신체적 폭력, 따돌림, 말다툼의 빈도가 감소하였다. 연구결과와 관련 하여 논의를 전개하였다.
