In this paper, the accommodations information system is proposed which provide convenience information to the elderly and disabled using Web Services. Our goal is to provide information for convenient mobility. The proposed system collects data from the information management server through Web Service APIs. Also, it implement web-pages that is consists of image and text using gathered data.

Bednar tumor was described by Bednar in 1957. The histologic pattern of this tumor shows similar to dermatofibrosarcoma protuberans (DFSP) but melanin pigments are scattered within the tumor, It s rare neoplasm accounting for approximately 1-5% of all case of DFSP. Clinically, this tumor is considered to be intermediated malignancy, because of slow growth and frequent local recurrence and lack of distant metastasis. The majority are located on the trunk and the upper and lower extremities, but extremely rate in the head and neck area. Microscopically, this tumor is characterized by tight storiform spindle cells and long slender cells that admixed with a small population of melanin containing dendritic cells. This dendritic cells are the primary features distinguising this lesion from conventional DFSP. Complete surgical excision and close follow-up case are necessany for this neoplasm because of probable intermediate malignancy. A patient was admitted to Our Department of Oral and Maxillofacial Surgery due to swelling on right parotid area and numbness of the right lower lip on September, 1994, By clinical examinations and C-T finding, we dignosed tentatively as myxoma or pleomorphic adenoma. Surgical excision of this tumor was performed with parotidectomy and mandibular osteotomy under the frozen biopsy. By final microscopic and electromicroscopic examination and immunohistochemical study, this tumor was diagnosed as Bednar tumor. So, we report a case of pigmented DFSP with review of literatures.

Many studies on electromyogram (EMG) system have been reported for the sake of persons with disabilities (PWDs) in rehabilitation training. Previously, almost all rehabilitation treatments made PWDs feel somewhat uncomfortable, which prompted them to consider these treatments repulsive. Therefore, this study provides some useful applications of EMG signals. The application module The developed GUI has display and save functions. The graph on the GUI windows assists the rehabilitation treatment by showing the condition of the muscles. The data saved from the GUI shows the conditions of the muscles of the PWDs and helps in the latter’s training. Because the application module provides visual effects, patients could relieve boredom, when participate in their treatment. In this paper, it is considered that the proposed systems can improve the rehabilitation treatment environment by using the EMG system and applications.

In this study, varicose vein phantom using vein mimic material and blood mimic fluid was suggested and fabricated. By sonicate the focused ultrasound to the fabricated phantom the changes of vein mimic material and bovine blood vein according to the sonication condition were monitored and compared. In addition, in order to simulate the varicose vein therapeutic environment more similarly, the thermal shrinkage according to the presence of flow were evaluated. As the experimental results, the thermal shrinkages of vein mimic material and bovine vessels were similarly observed, and the usefulness of proposed varicose vein phantom was confirmed. Consequently, the varicose vein phantom including the vein mimic material was thought to be useful to evaluate the ultrasonic varicose vein therapy.

Nasal bone fracture is common in mid-facial trauma patients. In these patients, facial bone and nasal bone fracture are reducted at same time, but definite nasal reduction is diffidulty in these patients because of nasotracheal intubation during general anesthesia and facial swelling in early facial trauma patients. If nasal packing and MMF are needed, there are difficult to maintain the reducted nasal bone because of some difficulty in airway maintenance after nasal packing and increasing the patient discomfort. So postoperative nasal deformity is more common in these combined patients. Secondary rhinoplasty is necessary in these patients who have deformed nasal bone, and there are many methods and materials for secondary rhinoplasty. But if primary nasal bone was reducted symmetrically, it is easy in secondary rhinoplasty. We present 7 cases of secondary rhinoplasty in mid-facial trauma patients who had combined nasal bone fracture. In these patients, primary nasal bone reduction carried with closed reduction method during primary facial bone reduction. About 6 months later, we performed secondary rhinoplasty with iliac bone and alloplastic materials. So we report these cases with literatures.
