본 연구의 목적은 과학활동을 중심으로 한 수와 사회 통합 교육 활동 수업 사례에서의 유아 반응을 분석하는 것이다. 분석 대상은 충북지역 M유치원 만 5세 유아 5명의 활동 수업 사례들이다. 「물」을 주제로 하여 총 10회 이루어진 교육활동은 선행연구(김숙자.김현정, 2003)에서 제시한 교수-학습과정 기본 모형을 토대로 하여 동기유발 단계, 초기개념 단계, 교수매체 투입, 개별 실험과 소그룹 토의를 통한 확장개념, 심화개념 단계로 재구성 하여 이루어졌다. 분석 결과 초기개념의 단계에서는 물을 옮길 수 있는 물체 예측을 통한 분류 개념과 물을 담는 용기의 높이와 물의 양과의 관련성이 분석되었다. 확장개념의 단계에서는 수 관련 개념으로 분류 개념, 수세기, 순서 짓기, 서수 개념, 높이, 크기, 길이, 양, 무게의 측정개념이 분석되었다. 사회 관련 개념은 문제해결을 위해 토의, 실험하기가 계속 순환되는 과정을 통해 나타난 협동하기, 다른 사람 의견 존중하기의 사회관련 개념이 분석되었다. 심화 개념의 단계에서는 물의 양과 물이 흘러나오는 속도, 물체의 형태변화와 부력의 관련성, 가라앉는 물체를 뜨는 물체에 올려놓는 위치와 부력의 관련성이 분석되었다. The purpose of this study was to analyze teacher's teaching-learning strategies and young children's responses to the science integrated study with mathematics and social studies for young children, based on the basic process model of teaching-learning. The basic process model of teaching-learning is a remodeling which is basic process model of teaching-learning. This was researched by Kim, Suk Ja;Kim, Hyun Joung(2003). To achieve this purpose, actual class episodes were analyzed. The episodes from the classes were derived from 10 sessions of interaction between teacher and 5 kindergarten children. With priority given to scientific activities, educational activities were integrated into mathematics, science and social study. The subject of scientific activities was water. Contents of activities were organized with activities to understand concepts of the volume of water and the velocity of water flow. A qualitative analysis was used to access responses of young children to teaching-studying strategies of teachers in case studies. As a result, young children could have their own scientific ideas about the volume of water, the relationship between volume of water, velocities of water flow, and buoyancy. They could understand the concept of mathematics in ractical exercise. By repetitions of experiments and discussions to solve problems, young hildren could realize the concepts of sociality such as cooperating with each other and respecting other people's opinions.

과립상 세포종은 Schwann 세포 기원으로 생각되며 인체에 비교적 드물게 발생한다. 과립상 세포종은 전신 어느 곳에서나 발견될 수 있으나 주로 혀, 구강, 피부 혹은 유방 등에서 호발하며 드물게 위장관에서 발견된다. 위장관에서는 식도에서 가장 호발하며 다음으로 위, 대장 순이다. 과립상 세포종은 대부분, 특히 위장관에서는 양성이며 소수의 악성 병변이 보고되었다. 이러한 이유와 함께 수술 전의 진단이 어렵기 때문에 과립상 세포종에 대한 근본적인 치료는 현재까지 외과적 절제술이다. 최근에 시도되는 치료방법들로는 내시경적 레이저 치료, 용종절제술, 내시경적 점막 절제술 등이 있다. 저자들은 상부 소화관 내시경검사를 시행하여 식도 과립상 세포종을 진단하고 내시경적 점막 절제술을 시행하여 합병증 없이 퇴원하여 현재 재발없이 경과 관찰중인 1례를 경험하였기에 보고하는 바이다. Granular cell tumors, which occur infrequently, are probably of Schwann cell origin. They can occur almost anywhere in the body but usually affect the tongue, oral cavity, skin, or breasts and are rarely found in the gastrointestinal tracts. The esophagus is the most frequent gastrointestinal site, followed by the stomach and the colon. Granular cell tumors are generally benign, especially in the gastrointestinal tract, some malignant lesions have been reported. For this reason, and also because preoperative diagnosis is difficult, the standard treatment for granular cell tumor has until now been surgical excision. In recent years, other therapeutic methods is endoscopic laser therapy (ELT), polypectiomy, endoscopic mucosal resection (EMR). We report a case of esophageal granular cell tumor which was diagnosed by an endoscopy and managed using an endoscopic mucosal resection without complication.

This study was performed to assess the radiopacity of a variety of root canal sealers according to the Specification concerning root canal sealers. Ten materials including Tubli-Seal™, Kerr Pulp Canal Sealer™, AH 26^(R), AH plus^(R), AH plus jet™, Ad seal™, Sealapex™, NOGENOU™, ZOB seal™, Epiphany™, and dentin were evaluated in this study. In the first part. densitometric reading of an each step of aluminum step wedge on occlusal film was performed at different voltage and exposure time. In the second part, ten specimens were radiographed simultaneously with an aluminum step wedges on the occlusal films under decided condition. The mean radiographic density values of the materials were transformed into radiopacity expressed equivalent thickness of aluminum (mm Al). The following results were obtained 1 Among the various conditions, the appropriate voltage and exposure time that meet the requirement density was 60 kVp at 0.2 s 2 All of the materials had greater radiopacity than 3 mm Al requirement of ANSI/ADA specification No. 57 (2000) and ISO No. 6876 (2001) standards. 3 The radiopacity of materials increased as thickness of materials increased. 4 The mm Al value of each specimen at 1mm in thickness has a significant difference in the statistics. It suggests that root canal sealers have a sufficient radiopacity that meet the requirement. 다양한 근관전색제는 방사선 사진상 주위 해부학적 구조와 구별될 만한 방사선 불투과성을 나타내야 한다 따라서 이런 물질들이 근관에 충전될 때의 방사선 불투과성 정도를 평가해야 할 필요성이 대두되고 있다. 본 실험에서는 다양한 근관전색제들의 방사선 불투과성을 평가하고자, 방사선 노출조건에 따른 aluminium step wedge에 대한 광학 밀도를 알아보고, 그 중 적절한 노출조건을 선택하여 수종의 근관 전색재의 방사선 불투과성 정도를 알루미늄 두께로 환산하여 비교해 보고자 한다. 방사선 불투과성의 기준을 위해 11개의 step으로 구성된 aluminum step wedge을 사용하여, 60kVP, 70kVp관전압 상태에서 각각 0.2, 0.3, 0.4초 그리고 0.2, 0.3, 0.33초의 꼭 노출시간으로 교합필름상에서 방사선 촬영후 적절한 노출 조건을 구하였다. 직경 5mm 각각의 두께 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 mm인 10종 (Tubli-Seal™, Kerr pulp Canal Sealer™, AH26^(R), AHplus^(R), AH plus jet starter kit™, Ad seal™, Sealapex™, Nogenol root canal sealer™, ZOB seal™, Epiphany™)의 근관전색재 시편을 각 재료와 두께당 10개씩 제작한 후, 동일한 두께의 상아질 시편, aluminum step wedge와 함께 정해진 노출시간에 따라 방사선 촬영을 하였다. 모든 필름은 자동현상기로 현상하였다. 시편의 방사선 흑화도를 densitometer로 5회 반복 측정 후, 평균값을 구하여 알루미눔 두께로 환산하였다.얻어진 정보를 분석하여 다음의 결과를 얻었다. 1 관전압 60 kVp에서 노출시간 0.2, 0.3, 0.4초, 70 kVp에서 0.2, 0.3, 0.33초로 변화를 주어 방사선 촬영을 하였을 때 흑화도가 ISO No. 6876 규격에 가장 적합한 것은 60 kVP, 0.2초 일 경우였다. 2 측정된 근관 전색제의 방사선 불투과성은 2.29 mm Al (N0GEN0L)로부터 13.69 mm Al (AH Plus jet)까지 다양하게 나타났으나, 모두 ANSI/ADA specification (2000) 또는 ISO No. 6876 (2001) 규격이 제시한 최소한 3mm Al 이상의 방사선 불투과성을 지녀야 한다는 기준에 적합하였다. 3 재료의 두께가 증가할수록 방사선 불투과성은 증가하지만, 정비례하지는 않았다. 4 각 실험재료의 1 mm 두께의 시편에 대한 mm Al값들은 통계적으로 유의한 차이가 있었다. 이상의 결과는 본 실험에 사용된 수종의 근관 전색재는 모든 규격에 적합한 방사선 불투과성을 가지고 있음을 시사한다.

A 35-year-old man was referred to the department of Oral and maxillofacial surgery of Chonnam university hospital for the chief complaint of asymptomatic swelling on the buccal vestibule of upper right canine area. Radiographs revealed that the upper right canine was impacted and there was a well-circumscribed pericoronal radiolucency related with the canine. Multiple radiopaque foci were scattered in the radiolucent lesion, and the roots of the lateral incisor and the first premolar related to the lesion showed external resorption. The radiographic features of this lesion were typical of adenomatoid odontogenic tumor, but considering the gender and age of the patient, the tentative diagnosis was made as calcifying odontogenic cyst. Microscopically this lesion was diagnosed as calcifying odontogenic cyst, Because calcifying odontogenic cyst has no pathognomonic feature of radiographs, to consider radiographic features with clinical findings is necessary in order to establish more correct diagnosis.(Korean J Oral Maxillofac Radiol 2000; 30: 223-227)

S. H. SHIN, T. W. KIM, M. S. KWON, S. G. GO, K. J. PARK. Analysis of the angular momentum on the lower extremity by change of starting block angles. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 165-175, 2004. The aim of this study is to show the effect of starting block angle on the starting motion of sprinters using a crouching start. After installing starting blocks on forced platform, and having four highly comparative sprinters use the starting blocks, I analyzed the angular momentum of a crouching start. From the results of the analysis, the following conclusions could be drawn: There were differences of angular momentum both in body's X, Y, and Z axes and in the thighs' X axes, but not in the pelvis and lower legs. As to the general change of block angle, we noticed that an angular momentum for each segments was higher at an angle of 50 to 55 degrees.
