In the upper gastrointestinal tract, in particular, there are parts consisting of esophageal sphincter muscles to carry out physiologic functions, which causes impairments when removed, as well as such complications as mucosal injuries, bleeding and even perforations in the case of foreign bodies with large size and/or sharp angles. Therefore, it is essential to use an appropriate type of supplementary instrument for a safe procedure. Frequently utilized supplementary instruments are overtube, protector hood, latex glove and transparent cap. We report a case in which authors were successful in removing a watch bend consisting of metal ring from gastric body while using a modification of a widely available drip chamber of fluid set attached to vertical end of endoscopic device.

효과적인 교정치료계획의 수립을 위하여 치열군의 저항중심의 위치에 대한 평가는 필수적이다. 이번 연구의 목적은 상악 치열군(4전치, 6전치, 14치아)에서 치조골 손실에 따른 저항중심의 위치변화를 조사해보고자 하였다. 상악 전치열 14개 치아와 치주인대 및 0 mm, 2 mm, 4 mm 손실된 치조골의 3차원 유한요소 모델을 제작하였고 각 치아군(4전치, 6전치, 14치아)별로 치관부를 협측, 설측호선 및 splint wire로 고정하여 치아군 모델을 제작한 후 상악 중절치의 절단연 중점에서 연장된 splint wire에 4전치와 6전치군에는 200 g, 14치아군에는 400 g의 후방 견인력과 압하력을 적용하여 저항중심의 수직적, 수평적 위치를 분석하였다. 4전치군에서 저항중심의 수직 위치는 치조골 0 mm, 2 mm, 4 mm 손실에 따라 중절치의 절단연에서 치근방향 13.5 mm, 14.5 mm, 15 mm, 수평 위치는 후방 12 mm, 12 mm, 12.5 mm, 6전치군에서는 치근방향 13.5 mm, 14.5 mm, 15.5 mm, 후방 14 mm, 14 mm, 14.5 mm, 14치아군에서는 치근방향 11 mm, 13 mm, 14.5 mm, 후방 26.5 mm, 27 mm, 25.5 mm에 위치하였다. 모든 치아군에서 저항중심은 치조골 손실에 따라 치근첨 방향으로 이동하였으나, 치조정과의 거리는 가까워졌고, 4전치군과 6전치군에서 저항중심은 치조골 손실에 따라 후방으로 이동하였으나, 14치아군에서는 치조골 2 mm 손실 시에는 후방으로 이동하였으나, 4 mm 손실 시에는 전방으로 이동하였다. Objective: The aim of this study was to investigate the changes in the center of resistance of the maxillary teeth in relation to alveolar bone loss. Methods: A finite element model, which included the upper dentition and periodontal ligament, was designed according to the amount of bone loss (0 mm, 2 mm, 4 mm). The teeth in each group were fixed with buccal and lingual arch wires and splint wires. Retraction and intrusion forces of 200 g for 4 and 6 anterior teeth groups and 400 g for the full dentition group were applied. Results: The centers of resistance were at 13.5 mm, 14.5 mm, 15 mm apical and 12 mm, 12 mm, 12.5 mm posterior in the 4 incisor group; 13.5 mm, 14.5 mm, 15 mm apical and 14 mm, 14 mm, 14.5 mm posterior in the 6 anterior teeth group; and 11 mm, 13 mm, 14.5 mm apical and 26.5 mm, 27 mm, 25.5 mm posterior in the full dentition group respectively according to 0 mm, 2 mm, 4 mm bone loss. Conclusions: The center of resistance shifted apically and posteriorly as alveolar bone loss increased in 4 and 6 anterior teeth groups. However, in the full dentition group, the center of resistance shifted apically and anteriorly in the 4 mm bone loss model.

Objectives : Nowadays many studies with MRI have reported structurai abnormalltles of corpus callosum of schizophrenic patients. However, the results are various and inconstant. In this study, we attempted to identify structural change of C O ~ U S cailosurn. Method : We measured the size of corpus callosum of the 24 schizophrenia patients (male 11, female 18) who were diagnosed by DSM-IV (19943, visited at department of psychiatry, catholic university hospital of Daegu from January 2002 to December 2003, by using midline sagittal slice of MRI. These results were compared with the size of corpus callosum of 25 controls (male 7, female 78). We divided corpus callosurn into 7 areas. We calculated and compared the areas of each subregion, mid-sagittal cerebral area, and entire corpus callosum. The results were analyzed by independent t-test. Result :When we compared subregion to corpus callosum adjusted wth mid-sagittal cerebral area, schlzoph-renia patients had significantly smaller genu (1.64k0.32 vs. 1.43k0.26 p<O.O5) and splenium (2.16f0.27 VS. 1.96+0.30 ; ~(0.05). Similarly, the ratio of total corpus callosum to midline sagittal cerebral area (%)(7.50*0.72 vs. 6.90t0.82 ~(0.05) was significantly smaller In schizophrenia than control group. Conclusion : In this study, we found significant differences in corpus callosum between schizophrenic patients and normal control group.

The purpose of this study is to reveal the factors leading to the problem of unilateral condylar fractures and suggest a treatment guideline of treatment for good prognosis in surgical treatment, The factors can be age, sex, fracture site, degree of displacement, posterior occlusion loss, post-operative alteration of condylar head position, post-operatlve condylar head resorption, and maxillomandibular fixation period. One hundred and eleven patients with unilateral condylar fractures, who were treated by surgical method from 1990 Feb. to 2000 Feb., were studied. Minimum follow-up period was 6 months. The results were as follows ; 1. In the age group of 41 ∼60, females had significantly higher complication rate than males, therefore we must be careful about treatment of female in this age group 2 In level I fractures of the mandibular condyle, because there were abundant complications when the patients were treated with fragment removal, conservative treatment is recommended over the surgical approach. 3. There were no differences in the complication rate, in the level Ⅱ, Ⅲ fractures. but were severe complications in the cases of patients treated by Dr.Nam's method or fragment removal. Therefore, open reduction and internal fixation is recommended over Dr.Nam's method or fragment removal. 4. In level Ⅳ fractures, open reduction and internal fixation is recommended 5. Although there was a higher complication rate depending on the degree of deviation, there was no correlation between the degree of deviation and development of complications in each level of fracture 6. Because the complication rate was higher in cases of condylar resorption, vertical dimension loss, and alteration of condylar head position, we must make an effort to prevent such complications during treatment

The authors has made an investigation on the water pollution of Kum River in chungnam province area from January to December 1981 and discusses the results of the water quality for the water samples were taken from 5 stations along the Kum River basin that is, Caechung dam (Ⅰ), Meapo(Ⅱ), Yeungi(Ⅲ), Gongju(ⅳ) Bueyeu(ⅴ). It is confirmed, by the analysis of B.O.D., C.O.D., S.S. and coliform that the Kum rever water was relatively less polluted than the other. Therefore it may be suitable still as source of water system. The relationships between pollutants in the Kum River Basin are as follow; B.O.D.(㎎/ℓ)=1.30C.O.D.-0.05(㎎/ℓ)
