Purpose : The purpose of this study was to investigate the effect of pelvic tilt exercise with changing the body position on foot contact pattern in the hemiplegic patients. Methods : Thirty seven hemiplegic patients were randomly divided 3 groups; control group (CG), sitting exercise group (SIEG) and standing exercise group (STEG). F-mat system and F-scan system were used for the measurement of foot contact pattern of hemiplegic side in walking. Data were analyzed statistically using paired t-test and one-way ANOVA. Results : The results were as follows : 1) Contact area of CG and SIEG were not significant difference in walking. Contact area of STEG was significant increased in walking. 2) Anteroposterior distance of COP of SIEG and STEG were significant increased in walking. Conclusion : These results suggest that pelvic tilt exercise in sitting and standing position are effective in the improvement of Anteroposterior distance of COP and gait stability are increased in only standing position.

Solid and papillary epithelial neoplasm (SPEN) of the pancreas is a rare tumor with low malignant potentiality that usually occurs in young females. Preoperative evaluation, especially radiologic tests, including ultrasonography and CT scan, is helpful in the diagnosis. These studies demonstrate a well-demarcated large mass with solid and cystic portions, frequently in the tail or body of the pancreas. Complete resection is usually curative, however local invasion and/or metastasis may occur. The authors report a case of a solid and papillary epithelial neoplasm of the pancreatic body in a 14-year old child at St. Benedict Hospital and review the literature.

Epidermoid cyst is a cystic form of teratoma and believed to be derived from trapped embryonic cells along the lines of embryonic closure. A 28-year-old woman presented with a painless swelling over the left mandibular area. On panoramic view, the mandible revealed a $5.5{\times}2.0\;cm^2$ multilocular radiolucent lesion of the left mandibular body and a computed tomography scan showed expansion of both the buccal and lingual plates in the same area. Microscopy found stratified squamous epithelium of the cystic wall and cystic contents of keratinized material. The histological diagnosis wasan epidermoid cyst. The most common location of epidermoid cyst at the head and neck is in the orbit (47%), followed by the mouth floor (23%) and the cervical area (9~24%), but in the jaw bone, it is considered very infrequent. We report the uncommon epidermoid cyst in the mandibular body that had a good healing outcome after treatment with a conservative marsupialization during the 40 months follow-up.

Clinical application of positron emission tomography (PET) is rapidly increasing for the detection and staging of cancer at whole-body studies performed with the glucose analogue tracer 2-[fluorine-18]fluoro-2-deoxy-D-glucose (FDG). Although FDG PET cannot match the anatomic resolution of conventional imaging techniques in gastrointestinal and abdominal organs, it is particularly useful for identification and characterization of whole body at the same time. FDG PET can show foci of metastatic disease that may not be apparent at conventional anatomic imaging and can aid in the characterization of indeterminate soft-tissue masses. Most gastrointestinal cancer need to surgical management. FDG PET can improve the selection of patients for surgical treatment and thereby reduce the morbidity and mortality associated with inappropriate surgery. FDG PET is also useful for the early detection of recurrence and the monitoring of therapeutic effect. The gastrointestinal cancers, such as gastroeso-phageal cancer, colorectal cancer, liver cancer and pancreatic cancer, are common malignancies in Korea. PET is one of the most promising and useful methodology for the management of gastric cancer as well as other gastrointestinal cancers.

Current prostheses for amputees are generally extrinsic wearing socket type that the coupling between body stump and appliance wraps the soft tissue and this structure causes several problems :applying direct weight to soft tissue such as skin and muscle, skin trouble of contacting area and pain. In this study, osseointegration implant is a method to directly connect prosthesis to the residual stump skeletal tissue of arm, finger and leg through surgical operation. Technology presented in this paper essentially solves the problems of pain and abnormal weight transfer system indicated above and recovers the functions of the amputated arm and leg. In this paper, implant shape was designed for the first step for the development of osseointegration implant and then we studied the possibility to apply this osseointegration implant to human body by performing implant insertion operation to beagle tibia for the clinical animal test and normal beagle's gait analysis was executed in order to quantitatively verify the beagle's skeletal functions after the implant insertion.

Considerable attention has been focused on digital X-ray systems with transmission. However, only a few attempts have been made using X-ray backscatter systems. This study developed a Data Acquisition System (DAS) for backscattered X-rays. The imaging system used X-ray backscatter at low energy levels, which has unique advantages in terms of acquiring information that cannot be obtained using the transmission system. Such systems are of potential benefit in the medical, industrial, security and military fields because of its practical benefits and the low doses used. The developed system is a similar body scan system. Experiments were carried out using a several metal materials and a fish, which produces results similar to those obtained using the human body during X-ray testing.

Intraosseous neurilemmoma(Schwannoma) is an extremely rare benign neoplasm. The site most commonly involved is the mandible. This occurrence is understandable because of the length of the inferior alveolar canal through the mandible. No other bone contains a canal that transmits a neurovascular bundle of such size and length. We report on a peripheral and central neurilemmoma along pathway of inferior alveolar nerve of the lower lip and mandible in a 28-year old man. A panoramic radiograph of the mandible showed a well-defined bilocular lesion with a thin uniform sclerotic margin located in the ramus and body of the mandible. The CT scan confirmed a well-defined lesion with thinning of the cortex of the body of the left side of the mandible. Histologically, the lesion was a cellular neoplasm with distinct palisading and numerous Verocay bodies. Complete excision was achieved by removing the tumor with the inferior alveolar nerve.

This study analyzed the total number of 19,636 patients and radiation technologists, 11,433 of male and 8,203 of female by examined body parts, age, types of detectors, the using contrast enhancement and working condition of the technologists, regular staffs or rotation-duty staffs, based on the K-DOS program distributed by FDA with the DLP value of diagnostic evaluation. The result shows that the effective radiation dose was 0.7mSv~41.7mSv for each region and male patients had more radiation exposure than females. And the amount of exposure was also affected by the types and the method of detectors. Furthermore, the regular staffs took the role of helping the patient to get reduced amount of radiation exposure than rotation duty-staffs. Computed tomography (CT) use has increased dramatically over the past several decades. In this reason, to support the patients and the workers' health in the field, the hospitals should apply specialized regular working radiation technologist system and manufacturing companies of those CTs should develop low medical radiation exposure devices.

Objectives : This study was performed to find out the relationships between abdominal fat and eating attitude in obese climacteric women. Methods : 42 obese climacteric women were recruited in August 2007. Anthropometry has been done and abdominal fat distribution had been assessed by CT scan at the level of L4-5 and eating attitude was measured using Korean Eating Attitude Test-26. Results : There were significant correlations between body mass index, percent of body fat and eating attitude. Total abdominal fat and visceral fat also increased with KEAT-26. Conclusions : There were relationships among eating attitude total fat, abdominal fat and visceral fat in obese climacteric women.
