This report is the study for laser scanning. Scanning control of $CO_2$ laser, He-Ne laser, used for the treatment of body skin, has relatively low band about hundered Hz. It could be used as a substitiute for expensive galvanometer that is the established scan method, which operates the number of KHz movement by using step motor when it operates low speed. To increase the accuracy of step motor's the angle of rotation, We could materialize 100Hz low band by using open loop, closed loop method with microprocessor. This causes it to be stable even direction by attaching electric capacity sensor. Therefore, We could expect to reduce the cost by manufacturing low band scanner rather than costly feedback galvanometer.

A 22 year old soldier was discovered on routine study for discharge to have a mass in the posterior mediastinum He was admitted due to high fever and improved by antibiotic treatment for 2 weeks. Chest PA, apicogram, myelogram and CT scan demonstrated enlargement of the neural foramen at the T1 level with erosion of the posterior aspect of the vertebral body and the pedicle contiguous with the intrathoracic mass, A myelogram showed a large extradural defect at the T1 level on the left. There were no clinical signs of cord compression. A standard posterolateral thoracotomy incision was made with extension to high thoracic vertebra. The 3rd rib was resected and the angles of the posterior portion of 1st and 2nd ribs were cut and rib heads were removed. Extrapleural neurilemmoma 6x6 cm was resected intrathoracically. And after removal of the pedicle and the lamina, intraspinal extradural mass 3 X 2 cm was resected carefully with trivial tearing of the dura which was sealed with gel-foam and pleura. There was ma postoperative neurological complication.

A 12-month-old boy was diagnosed with agenesis of the right lung. Mediastinal deviation progressed to the diseased side as the patient matured; therefore, tracheal distortion developed. As a result, tracheal compression developed between the vertebral body and aorta. The patient was repeatedly admitted to the hospital because of recurrent pulmonary infection and combined severe respiratory distress. Diaphragm translocation was performed to treat the patient. The postoperative course was favorable, and computed tomography scan findings and symptoms had improved at 1 year after surgery.

This case report describes the immediate loading of narrow diameter implants in the mandibular incisor area using full-digital flow. The 3-dimensional position of the implants was planned using digital software, and the corresponding surgical template was fabricated. The implants were inserted immediately after extraction and on the same day, the interim abutment and bridge were placed. At 8 weeks after surgery, the stability of the implants was measured and a digital impression was made using a scan body. Customized titanium abutments and a cement-type full zirconia bridge were delivered. At 36 weeks' follow-up, no clinical or radiographic complications were detected, and the patient was satisfied with the results.

Purpose: Whole-body CT is a very attractive diagnostic tool to clinicians, especially, in trauma. It is generally accepted that trauma patients who are not alert require whole-body CT. However, in alert trauma patients, the usefulness is questionable. Methods: This study was a retrospective review of the medical records of 146 patients with blunt multiple trauma who underwent whole body CT scanning for a trauma workup from March 1, 2008 to February 28, 2009. We classified the patients into two groups by patients' mental status (alert group: 110 patients, not-alert group: 36 patients). In the alert group, we compared the patients' evidence of injury (present illness, physical examination, neurological examination) with the CT findings. Results: One hundred forty six(146) patients underwent whole-body CT. The mean age was $44.6{\pm}18.9$ years. One hundred four (104, 71.2%) were men, and the injury severity score was $14.0{\pm}10.38$. In the not-alert group, the ratios of abnormal CT findings were relatively high: head 23/36(63.9%), neck 3/6(50.0%), chest 16/36(44.4%) and abdomen 9/36(25%). In the alert group, patients with no evidence of injury were rare (head 1, chest 6 and abdomen 2). Nine(9) patients did not need any intervention or surgery. Conclusion: Whole-body CT has various disadvantages, such as radiation, contrast induced nephropathy and high medical costs. In multiple trauma patients, if they are alert and have no evidence of injury, they rarely have abnormal CT findings, and mostly do not need invasive treatment. Therefore, we should be cautious in performing whole-body CT in alert multiple trauma patients.

Three-dimensional body data has been used in many industry fields including the apparel industry. This research used data from a study of the changes in lower body girth measurements from a 3D scan study of 25 female subjects aged 18 to 24 in four postures; a standing posture, a $120^{\circ}$ knee bend posture, a one pace stepping posture, and a sitting posture with a $90^{\circ}$ knee bend. We used the information on the difference between standing and seated measurements to adjust ease values for pants patterns an evaluation of the appearance, and the comfort of the pants. Waist girth in the sitting posture increased 8% compared to a standing posture and the hip girth measurement increased 7%. A basic pants pattern (pants A) with 2.4cm ease at the waist and 2.6cm ease at the hip was developed and a pants pattern (pants B) was developed using the rates of lower body girth change with a 5.7cm ease (8% change) at the waist and 7cm ease (7% change) at the hip. The appearance assessment items of pants A in a standing posture were higher than pants B. On the other hand, most appearance assessment items of pants B in a sitting posture were higher than pants A, especially the ease of pants back waistline and the appearance of the whole back. Comfort assessment items of pants B in both standing and sitting postures were higher than the comfort assessment items for pants A, especially the location of pants waistline, the ease of pants at the waistline, and the ease at the abdomen. In order to find the best level of ease for better appearance and comfort in both standing and sitting postures, 20 pants were constructed with ease values at the waist and hip in increments of 1.1cm in the range between the ease values of pants A and pants B. A fit test was conducted to compare the average appearance and comfort ratings that identified the pants with the best ease values at the waist and hip. The highest total mean was achieved in the pants with a waist ease of 4.6cm and hip ease of 4.8cm.

Bone scan is known to be an effective tool for observing the state of soft tissues and bones of electric burn patients. It is also used for observing the progress of patients after debridement or skin graft as well as deforming to amputate specific body parts. To evaluate bone scan's role in electric burn, we analyzed bone scan 37 patients with electric burn. Among the 37 patients, 8 of 37 were injured in low voltage and 29 of them in high voltage. 27 patients received the electrical input through the hand, 6 through the scalp, 2 through the shoulder, 1 through the left chest wall and 1 through the left inguinal area. Among 29 patients received high voltage, 22 patients had the electrical output through the foot, 3 through the hand, 2 through the shoulder, 1 through the buttock and 1 through the left chest wall. Bone scans revealed cellulitis in 37 patients with 47 sites, osteomyelitis in 15 patients with 15 sites & bone defects in 4 patients with 4 sites. In 4 patients with skin graft or skin flap, follow up bone scan showed improvements of bony uptake in preoperatively bony defect area and all of them were healed without complication. There were 2 cases in which uptake increased in the myocardium, 1 in the liver and 6 in the kidney, however, serum calcium level, EKG, cardiac enzyme, liver and renal function tests were normal. In conclusion, bone scans are helpful in the assessment of injury sites after electrical insult and in differential diagnosis of cellulitis and osteomyelitis. It is also useful tool of assessment after skin graft or skin flap, however, it should be further evaluated about internal organ damage.

The purpose of this study is to provide basic information for the development of well-fitting and comfortable brassieres for women in their 30s, based on the classification of breast shapes by utilizing 3D body measurement data of women in the age group. The result of processing the measurements from the 3D body scan data through RapidForm 2006 shows that while the vertical body measurements decrease, the horizontal measurements, which indicates the degree of obesity, increase proportionally with age. Also, the relevant measurements for upper breasts increase proportionally with age, while the measurements for lower part of the breasts decrease as the degree of sagging increases. Four composition factors of the breasts were identified through the factor analysis: Factor 1 is the level of volume in the breasts and the surrounding area; Factor 2 is the position of nipples and the shape of upper part of breasts; Factor 3 is the position and vertical length of the breasts; Factor 4 is the shape of lower part of breasts; and Factor 5 is the shape of inner part of breasts and degree of width between both breasts. The breasts have been categorized into three distinctive shapes: Breast Shape 1, Breast Shape 2 and Breast Shape 3. According to the results of the cluster analysis, the largest percentage (36.68%) of women in their 30s falls into the category of Breast Shape 2 with small volume and flat upper breasts, followed by Breast Shape 1 (32.66%) with large volume in the upper and lower parts of breasts, and large side to side area, and Breast Shape 3 (30.65%) with average volume and width between breasts.

This study develops tight-fitting torso patterns for performance garments by taking into account the skin deformation generated directly from a 3D scan during arm movements. The skin deformation caused during the arm movements was scanned after scanning the skin surface stamped with a circle. To create a torso pattern in response to skin deformation, the ratio and direction of the skin deformation were first measured and analyzed so that the 3D human body could be segmented. After translating, the 3D skin surface was segmented into 2D flat patterns, designing nude patterns and reducing them as well as tight-fitting shirts: the skin deformation segment shirts were made in response to the skin deformation. The features of the fabric deformation and the garment pressure were analyzed and evaluated. In comparison with a clothing construction segment shirt, the diameter of the skin deformation segment shirt was smaller as well the ratios of extension and reduction was less. The garment pressure of the skin deformation segment shirt was higher. The skin deformation segment shirt fitted more tightly compared to a clothing construction segment shirt as it covered the body more thoroughly and was as comfortable as the other shirts with less fabric deformation made as the body moved.

In this paper, to merge whole 3D information of an occluded body from view point, the new image merging algorithm is introduced after obtaining images of body on the turn table from 4 directions. The two images represented by polygon meshes are merged using weight bipartite matching method with different weights according to coordinates and axes based on minimum distance since two images merged don't present abrupt variation of 3D coordinates and scan direction is one direction. To obtain entire 3D information of body, these steps are repeated 3 times since the obtained images are 4. This proposed method has advantage 200 - 300% searching time reduction rather than conventional branch and bound, dynamic programming, and hungarian method though the matching accuracy rate is a little bit less than these methods.
