A retrospective study has been carried out for 47 cases of traffic accident victims which was entered to the Dongguk Bundang O. M. Hosp. from Jan 1, 1999 to May 4, 2000. This study was focused on finding out the distribution, pattern of the traffic accidents, clinical characteristics of the patients, motives of their choosing oriental medical treatments, the kinds of oriental medical treatment. This results were as follows : 1. The highest incidence was shown in the age of twenties to thirties as much as 59.6% and the ratio of male to female was 17:30. 2. 80.9% of all patients was injured by car accidents. 68.2% of all patients was injured as drivers and passengers and 19.2% was injured as pedestrians. The highest type in the collision between cars, was rear impact. 3. The number of patient(61.7%) via other hosp. was more than that of the first visitor(38.3%) to our hosp. 4. In admission motives, The patients who had been treated by western medical treatment, expressed the dissatisfaction of that treatment, so hoped to be treated by oriental medical styles. Also The others wanted to be treated by oriental medical methods in the reason of no deep surgical, orthopaedical lesions 5. C-spine sprain(80.9%) was the most frequent out of all patients's diagnosis and then L-spine sprain(51.1%), contusion(46.8%), etc. 6. Head Cervix(80.9%) was the commonest pain region of all patients. and then shoulder back(70.2%), lumbar region(61.7%), etc. 7. In general, the pedestrian injuries were more serious than those sustained in the car as passengers. 8. After discharge, Duration of OPD treatment was long as much as that of admission treatment. 9. At first stage of admission period, Herb medication was frequently prescribed for hwalhyultonglakgige(活血通絡之劑). but As going to end stage, was frequently used for bogi(補氣) bohyul(補血), gudam(祛痰), ansin(安神).

This paper presents a vision based object width measurement method and its application where the light sectioning method is employed. The target object for measurement is a tread, which is the most outside component of an automobile tire. The entire system applying the measurement method consists of two processes, i.e. a calibration process and a detection process. The calibration process is to identify the relationships between a camera plane and a laser plane, and to estimate a camera lens distortion parameters. As the process requires a test pattern, namely a jig, which is elaborately manufactured. In the detection process, first of all, the region that a laser light illuminates is extracted by applying an adaptive thresholding technique where the distribution of the pixel brightness is considered to decide the optimal threshold. Then, a thinning algorithm is applied to the region so that the ends and the shoulders of a tread are detected. Finally, the tread width and the shoulder width are computed using the homography and the distortion coefficients obtained by the calibration process.

Purpose: Continuous use of a smartphone increases the angle of forward bending of the user's cervical vertebrae, causing pain in the shoulders and back, including the thorax, lumbar region, and vertebrae. Although there are many studies on changes in the cervical spine due to smartphone usage, the changes in the shoulders, thoracolumbar spine, and pelvic have rarely been compared. The purpose of this study is to investigate the change in the spinal segments, shoulders, and pelvic when using a smartphone with both hands while in the standing position. Methods: This study was conducted on 35 adults in their twenties. The selection criteria for the subjects were limited to those in a similar age group, thus excluding posture differences according to age, and to those who did not have specific diseases or pain in the spinal and musculoskeletal system for 12 months prior to the study. In this study, we used a 3D spinal diagnostic imaging system (Back Mapper, Frickenhausen) to compare the changing conditions in each vertebral segment before and during smartphone usage with both hands while in the standing position. Posture differences according to smartphone usage were compared using the paired t-test for the motion of each spinal segment. Results: This study showed that the thoracic and lumbar angle increased posteriorly during smartphone usage (p<0.05). In addition, the anterior rotation angle of the shoulder bone significantly increased, but no significant difference occurred in the pelvic region. Conclusion: Based on the results of this study, smartphone usage with both hands while in the standing position showed that the spine, as a whole, forms a kyphotic curve. Therefore, we propose to present a postural guideline for correct smartphone usage, considering the change in each vertebral segment.

Osteochondroma is a bone tumor with cartilaginous growth potential that generally appears near the growth plate of long bones in areas such as hip, knee, and shoulder joints, related to the nature of endochondral ossification and it is known a common benign bone tumor. However, it has been very rare in craniofacial region possibly because craniofacial bone is largely formed by intramembranous ossification. Moreover, reports on the solitary type of osteochondroma in mandibular condyle has been extremely rare. Osteochondroma in mandibular condylar may show various symptoms similar to general temporomandibular joint disorders (TMDs), such as pain in the condylar area during mouth opening, internal derangement, facial asymmetry or posterior open bite. Therefore, it can be disregarded for a long time period without any adequate treatment. Surgical excision has been the treatment option for the solitary osteochondroma with very low recurrence rate reportedly. In this case report, a rare case of solitary osteochondroma developed in unilateral mandibular condyle is presented with emphasis on differential diagnosis with general TMDs.

Clothing fitness is strongly required in the apparel industry, and draping is an effective tool to increase fitness to the wearers. A more sophisticated and systematic information of the somatotype, accordingly, is necessary for better cress form design. This study was performed to provide fundamental data on middle aged women's upper torso for dress form designers and pattern makers by classifying the somatotype based on each individual's lateral view, and analyzing the characteristics of their somatotype. Data were analyzed by factor analysis, cluster analysis, analysis of variance. Factor analysis was used to 23 items from photometric measurment and cluster analysis was applied for classification of upper torso forms. Through cluster analysis using 5 factor scores, 3 somatotypes were categorized from th lateral view 1) Type I was straight somatotype in which the plumb line passes throught the lobe of the ear, the shoulder joing and the mid abdominal region laterally. This type of woman was slender and shorter than average. 2) Type II was bending somatotype in which the upper portion of upper torso is bent forward. This type of woman was taller and fatter than average. 3) Type III was swayback somatotype in which the upper portion of protruding point on the back is bent forward but the lower portion of protruding point had characteristic of turning over somatotype. This type of woman had storter length on the front and longer lenght on the back, slender type and flat chest.

This aims to improve match of clothes for export by offering material information about Chinese women's shape. Therefore, this categorizes the shape by where they live or how they are old and understands the tendency of spread of the shape. To categorize the subject by not size factor but form factor, data were compared and analyzed mainly with index based on measurement of the body. This selected specimen as 1,381 of Chinese women from 19 to 50 selected in random sampling in Shanghai and Beijing from 23th, June to 7th August in 2004. 1. Body shapes categorized by regional and age base are hardly different in its contents. The younger they are, the stronger the tendency of front side factors is, the older they are, the stronger the tendency of shoulder and back side factors is, so this shows that there are slight differences in degree of importance. 2. This is categorized by equal formations in regional and age base in all groups. Normal shapes record highest in the twenties and thirties, fat and skinny shapes record highest and lowest in the forties, respectively. Normal, fat and skinny show its range as respectively decreasing order in Shanghai and Beijing.

The motor complications after herpes zoster infection are uncommon, but, the association of muscular paralysis and zoster has been reported for several times. The association between diaphragmatic paralysis and zoster was for the first time reported by Halpern and Covner. The case presented below showed right diaphragmatic paralysis following herpes zoster of C3 and C4 region of dermatome on the right side. A 59-year-old man was found to have a paralysed hemidiaphragm within two months of the appearance of typical herpes zoster rashs involving his right shoulder and neck. Investigations, including bronchoscopy, failed to detect other cause for the diaphragmatic paralysis. We believe that the cervical zoster and diaphragmatic paralysis were causally related.

Fluorescence (FL) properties of a novel donor-acceptor dyad, comprised of mesitylene and 1,4-dicyano-2-methylnaphthalene (DCMN) subunits connected by an ether linkage, were elucidated. The dyad in cyclohexane exhibits FL arising from an intramolecular exciplex. In the crystalline state, the dyad does not emit light from intra- and inter-molecular exciplexes but rather displays FL that is nearly equivalent to that of 2-methoxymethyl-substituted DCMN. However, the emission spectrum of the crystalline dyad contains a shoulder in the long wavelength region, suggesting that weak intercolumnar charge-transfer interactions take place between columns consisting of the mesitylene and DCMN subunits.

Friction Stir Welding (FSW) is a solid-state process, where the objects are joined together without reaching their melting point. It has been shown that this method is a suitable way to join dissimilar aluminium alloys. The current article employed hole drilling technique to measure the residual stress distribution experimentally in different zones of dissimilar aluminium alloys AA6061-T6 and AA7075-T6 Butt welded using FSW. Results are compared with those of similar AA6061-T6 plates joined using a conventional fusion welding method called tungsten inert gas (TIG). Also, the evolution of the residual stresses in the thickness direction was investigated, and it was found that the maximum residual stresses are below the yield strength of the material in the shoulder region. It was also revealed that the longitudinal residual stresses in the joint were much larger than the transverse residual stresses. Meanwhile, Vickers micro hardness measurements were performed in the cross-section of the samples. The largest hardness values were observed in the stir zone (SZ) adjacent to the advancing side whereas low hardness values were measured at the HAZ of both alloys and the SZ adjacent to the retreating side.

PURPOSE: It is known that work stress was linked to WRMDs in workplace. The purpose of this study was to identify the characteristics of work related musculoskeletal disorders (WRMDs) related to job stress among prosthetists and orthotists. METHODS: Eighty-six self-reported symptoms of discomfort (SRSD) and job stress were collected by questionnaire and analyzed. RESULTS: The results were as follows: Over 70% of respondents had WRMDs. The shoulder was the most painful region and each of "within 15 minutes", "once a week" and "severe moving or doing exercise" items were main characteristics in the SRSD. Finally, the "repetition of simple work" item in job stress ranked as resulting in "often discomfort" in over 43% of respondents. Additionally, there was a statistically significant correlation between job stress and pain intensity (p<.05, $r_s$=.36). CONCLUSION: Further studies are needed to identify the factors affecting musculoskeletal symptoms and job stress of prosthetists and orthotists in Korea.
