BACKGROUND: Recently, the trend pursuing slimness is significantly increasing in adolescents. Because of distorted body image, excessive body weight control can cause problems of health. The goal of this study is to investigate the factors of distorted body image and its problems. METHODS: The survey was performed in a high school of Jindo island on May, 2000. All of 258 students in 1st and 2nd grade participated in this study by questionnaires. Thirteen truthless questionnaires were excluded in this study. Therefore 245 student were selected. RESULTS: Only 20% of 245 repliers were satisfied with their body figure. In male, 24.1% wanted weight loss, and 39.8% wanted weight gain. In female, 73% wanted weight loss. In a populations(BMI<20), 70 males wanted weight loss, whereas 35(52.2%) among 67 females want weight loss. According to these result, female stuedents wanted strongly weight loss than male. The factors which most influenced body figure were sports star in males(36.1%), and movie stars in female.(43.8%) A group of 58.4% of repliers has experienced body weight control. A group of 37% in male and 39.6% in female suffered from side effects. 77% of total hoped to be educated about adequate body weight control method. CONCLUSION: Almost of adolescents dissatisfied with their body figure, Many adolescent who is not obese attempt weight loss, and are sufferd from side effects. Therefore, it is required for effective education about body weight control and social attitude permitting adequate body image.

PURPOSE: The purpose of the present study was to compare scanning trueness and precision between an abutment impression and a stone model according to dental computer-aided design/computer-aided manufacturing (CAD/CAM) evaluation standards. MATERIALS AND METHODS: To evaluate trueness, the abutment impression and stone model were scanned to obtain the first 3-dimensional (3-D) stereolithography (STL) file. Next, the abutment impression or stone model was removed from the scanner and re-fixed on the table; scanning was then repeated so that 11 files were obtained for each scan type. To evaluate precision, the abutment impression or stone model was scanned to obtain the first 3-D STL file. Without moving it, scanning was performed 10 more times, so that 11 files were obtained for each scan type. By superimposing the first scanned STL file onto the other STL files one by one, 10 color-difference maps and reports were obtained; i.e., 10 experimental scans per type. The independent t-test was used to compare root mean square (RMS) data between the groups (α=.05). RESULTS: The RMS±SD values of scanning trueness of the abutment impression and stone model were 22.4±4.4 and 17.4±3.5 µm, respectively (P < .012). The RMS±SD values of scanning precision of the abutment impression and stone model were 16.4±2.9 and 14.6±1.6 µm, respectively (P=.108). CONCLUSION: There was a significant difference in scanning trueness between the abutment impression and stone model, as evaluated according to dental CAD/CAM standards. However, all scans showed high trueness and precision.

PURPOSE: To valuate the value of goose neck snare in removal of foreignbody in endovascular system. METHODS & MATERIAL: Foreignbody removal in endovascular system using goose neck snare were done in 4 cases. In one case, a broken guide-wire was located in left subclaviar vein and in three cases, guide-wires were located in vena cava. RESULTS: Technical success was achieved in all four cases. CONCLUSION: Goose neck snare technique is safe and effective in removal of Foreignbody in endovascular system.

Yolk sac tumors are rare malignant germ cell neoplasms that usually arise from the gonads. Extragonadal yolk sac tumors (EGYSTs) frequently occur in the mediastinum in post-pubertal females. EGYSTs in the pelvis are extremely rare, and to date, only thirteen cases have been reported in the English literature. Among them, the primary EGYST of the pelvic peritoneum in post-pubertal females has only been reported in ten cases. The present case describes a 26-year-old female diagnosed with primary peritoneal yolk sac tumor located in the rectouterine pouch. We report clinical and tumor imaging features, including ultrasound, computed tomography (CT), magnetic resonance images (MRI), positron emission tomography-computed tomography (PET-CT), and present a review of the literature.

A case of coil embolization in right superior thyroid artery pseudoaneurysm by stab wound is reported. A fifty-six-year old female, laceration and some bulging in right neck side. Aortic arch angiography, right common carotid angiography was done. Angiography shows 4 2 cm sized right thyroid artery pseudoaneurysm (Fig. 1) and (Fig. 2). We selected right superior thyroid artery by 3F micorofert (CooK, Bloomington, Ind.) and embolized by 2 4 mm (diameter), 2 cm (length) sized micro tornaido coil (CooK, Bloomington, Ind.). Post procedure right common carotid angiography was done. Angiography shows no visualized right thyroid artery pseudoaneurysm (Fig. 3).
