The objective of the study was to obtain standard sizes of body of the high school girls for designing clothes and developing pattern grading of clothes. In 1972, 342 students, selected by the stratified cluster random sampling method, at three high schools in Seoul were measured on forty-one items by the R. Martin method. Statistical techniques of mean, standard deviation, coefficient variable, maximum and minimum, range, t-test were utilized to analyze the data. The findings of the study were as follows ; 1. No differences were found among the age groups in the all measured variables. 2. Stature, bust girth, hip girth, acromion width, posterior waist girth/stature ratio of the high school girls were significantly smaller than those sizes of adult women. This result implies that those sizes will be increased as the students grow up. But upper arm girth, upper arm girth/bust girth ratio, and thigh girth/bust girth ratio were bigger than those sizes of adult women. Waist girth, thigh girth, total head height/stature ratio, acromion width/stature ratio, and foot length/stature ratio were nearly similiar to those of adult women. 3. According to the result of t-test, waist breadth, spinailiaca anterior height/stature ratio, thigh girth/bust girth ratio, and thigh/hip girth ratio of the 15 year old group were significantly different from those of the 16 year old group at the level of 0.05. Bust girth, weight, foot breadth, posterior croth length, and cervical height/stature ratio of the 16 year old group were significantly different from those of the 17 year old group at the level of 0.01. Hip girth, upper arm girth, waist breadth/stature ratio, and neck base girth/bust girth ratio of the 16 year old group were significantly different from those of the 17 year old group at the level of 0.05.
Objective : Computed tomography (CT)-based method of three dimensional (3D) analysis ($MIMICS^{(R)}$, Materialise, Leuven, Belgium) is reported as very useful software for evaluation of OPLL, but its reliability and reproducibility are obscure. This study was conducted to evaluate the accuracy of $MIMICS^{(R)}$ system, and inter- and intra-observer reliability in the measurement of OPLL. Methods : Three neurosurgeons independently analyzed the randomly selected 10 OPLL cases with medical image processing software ($MIMICS^{(R)}$) which create 3D model with Digital Imaging and Communication in Medicine (DICOM) data from CT images after brief explanation was given to examiners before the image construction steps. To assess the reliability of inter- and intra-examiner intraclass correlation coefficient (ICC), 3 examiners measured 4 parameters (volume, length, width, and length) in 10 cases 2 times with 1-week interval. Results : The inter-examiner ICCs among 3 examiners were 0.996 (95% confidence interval [CI], 0.987-0.999) for volume measurement, 0.973 (95% CI, 0.907-0.978) for thickness, 0.969 (95% CI, 0.895-0.993) for width, and 0.995 (95% CI, 0.983-0.999) for length. The intra-examiner ICCs were 0.994 (range, 0.991-0.996) for volume, 0.996 (range, 0.944-0.998) for length, 0.930 (range, 0.873-0.947) for width, and 0.987 (range, 0.985-0.995) for length. Conclusion : The medical image processing software ($MIMICS^{(R)}$) provided detailed quantification OPLL volume with minimal error of inter- and intra-observer reliability in the measurement of OPLL.
Purpose : The purpose of this study was to evaluate clinical efficacy of the arthroscopic anterior acromioplasty for the treatment of chronic impingement syndrome of the shoulder. Materials and Methods : Between July 1995 and December 1997, twenty seven consecutive shoulders of 26 patients with chronic impingement syndrome of the shoulder were treated by arthroscopic anterior acromioplasty. The patients who had severe osteoarthritis of the shoulder full thickness tear of the rotator cuff, and nonoutlet impingement were excluded. The clinical results were evaluated by using UCLA shoulder rating scale. The average follow-up was 2years 3months(range, 1year 7months to 3years 1 11months). Results : Twenty three patients$(85.2\%)$ were rated as excellent or good results, while four patients$(14.8\%)$ were fair. Twenty six cases$(96.3\%)$ were satisfied with the results of the operations, while one case$(3.7\%)$, who had Parkinsonian syndrome, ossification of posterior longitudinal ligament(OPLL) of the cervical spine, and spinal stenosis of the 5th and 6th cervical spine was not satisfied. Conclusion : Arthroscopic anterior acromioplasty was an effective treatment method, especially for relief of pain, for the treatment of chronic impingement syndrome of the shoulder. If the patient has the combined lesions in the cervical spine and the shoulder, and systemic lesions, these lesions may influence the results of treatment after operation, and cause the unpredictable results.
Statement of problem: A difficulty in achieving a passive-fitting prosthesis can be overcome by individual crown restoation of multiple implants. But individualized crown has another difficulty in control of contact tightness and stress distribution. Purpose: This in vitro study is to evaluate the stress distribution and the magnitude in the supporting tissues around Endopore implants with different crown lengths, interproximal contact tightness, and the splinting effects. Material & methods: Three Endopore implants($4.1{\times}9mm$) were placed in the mandibular posterior edentulous area distal to the canine and photoelastic model was made with PL-2 resin(Measurements Group, Raleigh, USA). Restorations were fabricated in two crown lengths: 9, 13 mm. For non-splinted restorations, individual crowns were fabricated on three custom-milled titanium abutments. After the units were cemented, 4 levels of interproximal contact tightness were evaluated: open, ideal($8{\mu}m$ shim stock drags without tearing), medium($40{\mu}m$), and heavy($80{\mu}m$). For splinted restorations, 3-unit fixed partial dentures were fabricated. This study was examined under simulated non-loaded and loaded conditions(6.8 kg). Photoelastic stress analysis was carried out to measure the fringe order around the implant supporting structure. Results: 1. When restorations were not splinted, the more interproximal contact tightness was increased among the three implants, the more stress was shown in the cervical region of each implant. When crown length was increased, stresses tended to increase in the apex of implants but there were little differences in stress fringes. 2. When nonsplinted restorations were loaded on the first or third implant, stresses were increased in the apex and cervical region of loaded implant. Regardless of interproximal contact tightness level, stresses were not distributed among the three implants. But with tighter interproximal contact, stresses were increased in the cervical region of loaded first or third implant. 3. When the nonsplinted restorations were not loaded, there were little stresses on the supporting structure of implants, but low level stresses were shown in the splinted restorations even after sectioning and soldering. 4. With splinted restorations, there were little differences in stresses between different crown lengths. When splinted restorations were loaded, stresses were increased slightly on the loaded implant, but relatively even stress distribution occurred among the three implants. Conclusions: Splinting the crowns of adjacent implants is recommended for Endopore implants under the overloading situation.

Objective : The purpose of this study was to evaluate long-term follow-up radiologic/clinical outcomes of patients who underwent anterior cervical discectomy and inter-body fusion (ACDF) with stand-alone cages (SAC) in a single academic institution. Methods : Total 99 patients who underwent ACDF with SAC between February 2004 and December 2012 were evaluated retrospectively. A total of 131 segments were enrolled in this study. Basic demographic information, radiographic [segmental subsidence rate, fusion rate, C2-7 global angle, and segmental angle changes)/clinical outcomes (by Odom's criteria and visual analog score (VAS)] and complications were evaluated to determine the long-term outcomes. Results : The majority were males (55 vs. 44) with average age of 53.2. Mean follow-up period was 62.9 months. The segmental subsidence rate was 53.4% and fusion rate was 73.3%. In the subsidence group, anterior intervertebral height (AIH) had more tendency of subsiding than middle or posterior intervertebral height (p=0.01). The segmental angle led kyphotic change related to the subsidence of the AIH. Adjacent segmental disease was occurred in 18 (18.2%) patients. Total 6 (6%) reoperations were performed at the index level. There was no statistical significance between clinical and radiological outcomes. But, overall long-term clinical outcome by Odom's criteria was unsatisfactory (64.64%). The neck and arm VAS score were increased by over time. Conclusion : Long-term outcomes of ACDF with SAC group were acceptable but not satisfactory. For optimal decision making, more additional comparative long-term outcome data is needed between ACDF with SAC and ACDF with plating.

Whiplash injury commonly seen in automobile accident. This type of acceleration-deceleration injury may rarely lead to unfavorable outcomes as in the case of retropharyngeal hematoma. Because this lesion has the possibility of compressing the potential airway acutely or gradually, not only the rapid assessment and treatment but also closed observation are needed. We report a case of a 20-year-old man, who sustained a whiplash injury from contact with the headrest of his seat after his car was involved in a rollover. He had no symptom except posterior neck pain initially, but complained odynophagia and acute dyspnea after 10 hours of admission. The diagnostic work-up comprising lateral radiograph, CT imaging disclosed the rare constellation of a retropharyngeal hematoma with cervical spine fractures. Medical treatment and close observation were sufficient for the patient because he had no progressive dyspnea or major dysphagia.

The use of fluoroscopy guidance together with the loss of resistance technique during epidural injections has been advocated lately; moreover, epidural injections in the absence of fluoroscopic guidance have a high rate of inaccurate needle-tip placement during the injections. However, the approach to the lower cervical and upper thoracic epidural space may be challenging due to its obscure lateral fluoroscopic views from overlying normal tissue structures. In this case, we report an alternative oblique C-arm fluoroscopy guided view approach to supplement the standard anterior-posterior and lateral fluoroscopic views to facilitate successful needle placement and precise anatomical localization of the epidural space.
Background: Pelvic exenteration is a procedure which includes enbloc resection of pelvic organs followed by surgical reconstruction. Aims include both cure and palliation but data for pelvic exenteration in Thailand are very limited. Objective: This study was conducted to evaluate characteristics of patients, operative procedure outcomes and complications. Materials and Methods: This retrospective review covered all of the charts of exenteration patients during January 2002 to December 2011. Baseline characteristic of the patients were collected as well as details of clinical results. Results: A total of 13 cases of pelvic exenteration were included. Most underwent total pelvic exenteration (9 cases) and the remainder posterior and anterior exenteration. Their primary cancers were ovarian, cervical and vulva. Mean operative time was 532 minutes (SD 160.2, range 270-750) and estimated blood loss was 2830 ml (1850, 1000-8000). Mean tumor size was 7.33 cm (3.75, 4-15). Mean hospital stay was 35.2 days (29.8, 13-109). The most common post operative complication was urinary tract infection. Overall disease free survival with a negative surgical margin was significantly better than in positive surgical margin patients (p=0.014). Conclusions: Surgical margin was the most significant prognostic factor for disease free survival, in line with earlier studies.

The purpose of this study is to use standard and downward slope of the keyboards with taping to influence electromyography of upper trapezius. The effect of taping raise a medical criticism, but we do an experiment on two kind of keyboards with taping in order to decrease stress of shoulder. Subjects are in Seonam university whose are twelve healthy adults in their twenties. This experiment used two kind of keyboards. Standard keyboard's degree is $0^{\circ}$ and another keyboard's degree is $-7.5^{\circ}$. Application of Kinesio taping attached belly of upper trapezius tightly. Measurement of electromyography attached posterior of acromion process go by spinous process of 7th cervical vertebra and upper trapezius. Method of analysis used Repeated measure two-way ANOVA. Result of this experiment, both shoulder's muscle activity increased(p<.05) when used standard keyboard and downward keyboard with taping used. We compared muscle activity that used downward keyboard than standard keyboard. Statistically, it dosen't increase in neck and shoulder(p>.05). Therefore, using a keyboard with upper trapezius's taping in order to decrease muscle activity isn't influenced.

Long term prediction of surgical result of skeletal class III has not been evaluated adequately because the stability of orthognathic surgery would be affected by not only set back amount of mandible but also many other factors like skeletal pattern, hyoid position, and airway size. The aimof this study is to discriminate the factors which affect the stability of post-treatment result of surgical outcome of sagittal split ramus osteotomy. We have collected 37 patients (male: 17, female: 20) from patients who have been treated at Orthodontic Department in Dankook University. The patients underwent 3 times Cephalometric X-ray taking at pre-, post-orthognathic surgery and after 12 months retention. The subjects were divided into 2 groups (Stable group: 21, Relapse group: 16) according to their relapse amount. We have taken following results from Students t-test and discriminant analysis. The discriminant factors which discern relapse and stable groupe among treatment change variables were BX and Ba-HY. Hyoid bone moved to posterior and inferior position due to surgery and repositioned superiorly and posteriorly during retention period. Skeletal patterns of the relapse group are smaller mandibular plane angle, anterior mandibular position, and greater distance from hyoid bone to cervical bone and mandible respectively.
