Purpose: This study examined the effects of the fascial distortion model (FDM) method on Cobb's angle. Methods: Fourteen subjects participated in this study. The idiopathic scoliosis group performed FDM treatments eight times in four weeks. A Shapiro-Wilks test was used to verify the normality of a group of idiopathic scoliosis patients. A paired t-test was performed to determine the satisfaction with the normality. Results: The difference in Cobb's angle was reduced significantly (p<0.05) by an average of $5.72^{\circ}{\pm}2.24$ from $15.51^{\circ}{\pm}1.81$ before the experiment. Conclusion: This study found that the use of the FDM method was effective in improving the Cobb's angle. The application of a FDM treatment appears to stabilize the fascia with decreased ability to adapt physiologically. The application of the CD and TB method of FDM treatment improved the asymmetry spine by dispersing moisture in fascia and improving the contraction and relaxation ability. The results suggest that the Cobb's angle is reduced when FDM is applied, thereby preventing the progression of curvature and avoiding psychological and physical problems that can arise from improving patients with scoliosis.

In the present study, we aimed to examine the effects of Schroth exercise(three-dimensional convergence exercise) on pulmonary function(vital capacity, and chest expansion), Cobb's angle, scoliometer angle, and erector spinae muscle activity. We examined 40 students with idiopathic scoliosis(Cobb's angle $10^{\circ}$). They were divided into the Schroth and conventional exercise groups, with 20 people in each group. Statistical analysis was performed by using SPSS 18.0 with a paired t-test(pre-post difference) and an independent t-test(between-group differnence). the result of were as follows; 1) After 8 weeks of Schroth exercise, significant improvements were observed in Cobb's angle, rib hump, vital capacity, chest expansion, and right thoracic longissimus muscle activity. 2) After 8 weeks of conventional exercise, a significant improvement was observed only in chest expansion. These findings indicate that the Schroth exercise program improved the Cobb's angle, rib hump, pulmonary function, and sEMG results. Therefore, this study demonstrates the usefulness of the Schroth exercise program for idiopathic scoliosis.

The TLSO was customized for this study in OO ortho-prosthesis institute from Jan. 1th., 2000 to Dec. 31th., 2000 and in order to measure effects of TLSO. 20 females in a growth period applicable to medical care took part in this study, they were on accidental spine scoliosis (From $15^{\circ}to35^{\circ}$). They were consisted of Group I(10 chest-bend) and Group II (10 dual-bend). The results were follows: 1. It showed the average difference in height by 1.37cm, 3.14cm in comparison between before and after TLSO, before and after one year and they were also statistically available(p < .05). 2. It showed the average difference in Cobb angle of a chest and waist by ($-10.95^{\circ},-8.50^{\circ}$), between before and right after TLSO. The results means that the Cobb angle of the chest and weist at right after TLSO was largely decreased, and it was also statistically available(p < .05). 3. It showed the difference in Cobb angle of the chest waist by $-9.50^{\circ},-7.35^{\circ} $ between before and one year after TLSO. It means that the Cobb angle of the chest and waist at the one year after TLSO was largely decreased, and it was also statistically available(p < .05). 4. It showed the difference in Cobb angle of the chest and waist by $2.34^{\circ},2.15^{\circ} $ between the right after and the one year after. TLSO, but the change of Cobb angle of the chest was regularly constant by a little increased, and it was also statistically available(p < .05). 5. In the measurement of the change of Cobb angle of the chest and waist according to the taking time on TLSO, it showed the slightest change in 10 people on TLSO for 23 hours by $13.30^{\circ},11.20^{\circ}$ , the change in 6 people on TLSO for 16 hours by $14.75^{\circ},12.67^{\circ}$, the change in 4 people on TLSO for 8 hours by $16.83^{\circ},14.00^{\circ} $ in this order. It means that the longer time on TLSO was to be the smaller the Cobb angle of the chest and waist, but it was not statistically available.

In order to investigate the Post-operative changes in scoliotic spine according to selection of fusion level a mathematical finite element model of King-Moe type II scoliotics spine system was developed. By utilizing this finite element scoliosis model surgical correction simulation procedures of pedicle fixation and derotation were simulated. In consequence of the calculation by changing the fusion Levels, postoperative changes like Cobb angle, apical vertebrae axial rotation (AVAR), thoracic kyphosis, and rib hump were Qualitatively analyzed. In the analysis of operative kinematics, the decrease or Cobb angle was most prominent in distraction than in deroation. Applying the rod derotation only was not effective in decrease of Cobb angle but just caused increase of At AR and rib hump. From the operative simulation, co-action or distraction and translation during rod insertion has major impact on Cobb angle decrease and maintenance of kyphosis. With rod rotation, Cobb angle decrease was obtained, but combined increase of AVAR and rib hump was simulation observed as well. The case of most extended instrumentation range with 60o rod rotation produced double decrease of Cobb angle, but the increase of rib hump and AYAR occurred corresponding1y. The optimum selection of fusion level was proved as one level less than inflection position of the thoracic spine curvature.

Objectives: This study was designed to investigate the correlation between cervical, lumbar lordosis and low back pain(LBP), sex, age and duration of LBP. Methods : Cervical, lumbar lordosis(by Cobb's Method) and Ferguson's angle were measured and evaluated in LBP group and control. Radiograph was taken in lateral direction, erect position. Cobb's angle between C1-C7, C2-C7, L1-L5, L1-S1 and Ferguson's angle were measured and investigated with statistical program. Results: 1. Cervical lordosis have no relation to LBP, sex and age. 2. Lumbar lordosis and Ferguson's angle have no relation to LBP and sex. 3. Cobb's angle L1-L5 have no relation to age. Lumbar lordosis from L1 to S1(Cobb's angle L1-S1) increased in old group(Age>40) compared to young group(Age${\leq}$40). 4. In LBP group, Cobb's angle L1-S1 have no relation to duration of LBP. Lumbar lordosis from L1 to L5(Cobb's angle L1-L5) decreased in acute LBP group compared to Chronic group. Conclusions : Cervical, lumbar lordosis and Ferguson's angle have no relation to LBP and sex. As far as age is concerned, old group have larger lumbosacral lordosis than young group. Acute LBP group have smaller lumbar lordosis(Cobb's angle L1-L5) than chronic group.

Purpose: It is known that the chronic absence of unilateral breast can cause spine curvature. The artificial breast manufactures take up the position of that possibility. This study was designed to evaluate the influence of the mastectomy on the spine and appearance of scoliosis among women who wanted delayed breast reconstruction. ted delayed breast reconstruction. Methods: The study population consisted of 47 women who underwent delayed breast reconstruction at our Department of Plastic Surgery from April 2001 to May 2007. The whole spine anteroposterior and lateral X-ray was taken to evaluate the Cobb's angle. As a general rule a Cobb angle of 10 is regarded as a minimum angulation to define scoliosis. We evaluated Cobb's angle and drew a correlation between the duration of the mastectomy state and the weight of the mastectomy specimen. Results: There were no family history of scoliosis, and no numbness or weakness in the upper or lower extremities. They had normal reflex and experienced no tenderness of the perispinal area. The Spearman Correlation Coefficient between Cobb's angle and the period that took time from the mastectomy to the X-rays and analysis between Cobb's angle and specimen weight was 0.032 and-0.115. there were no correlation between Cobb's angle and time, or between Cobb's angle and specimen weight. Conclusion: lthough the patients attribute their back pain and distorted posture to having received an one-sided mastectomy, it is unlikely that one-sided mastectomy causes spinal deformity and scoliosis.

PURPOSE: The purpose of this study was to describe the effects of short term Schroth exercise on the Cobb angle, angle of trunk rotation (ATR), cosmetic appearance, and quality of life (QOL) in idiopathic scoliosis patients. METHODS: Five subjects with idiopathic scoliosis, (female, 3; male, 2) curvature type: thoracic, 2; lumbar, 3 underwent short term Schroth exercise for seven days. The exercise was performed for 3 h long sessions per day. The Cobb angle and QOL were measured before and after the intervention. ATR and cosmetic appearance were measured once. Sessions consisted of one baseline, seven intervention and three follow-up phases. The sessions were conducted with a one day interval. RESULTS: After the intervention, the Cobb angle was found to be significantly improve (p <.05), while the QOL did not differ (p>.05). The ATR showed decreased trends in the intervention phase. Data points during the intervention and follow-up phases showed a decrease in comparison with data points at the baseline, indicating that Schroth exercise might be effective in reducing the ATR and that these effects can be maintained after the intervention. Cosmetic appearance did not showed changed trends during the Schroth exercise intervention phase. CONCLUSION: Our results suggest that short term Schroth exercise may be valuable in improving the Cobb angle and ATR in patients with idiopathic scoliosis.

The purpose of the study was to pay attention to the studies of P. Cobb which have actively been quoted in the international research of mathematics education for the last three decades and to look at the result and effect of his research. In particular, we in-depth studied theories and the methods of the study which he has tried to reduce the gap in the theory and practice and investigated effects of his research to the Korean societies of mathematics education. Cobb made special effort to integrate radical constructivism and social constructivism and used emergent theory and symbolic interactionism as theoretical background of the study. Also he analyzed the mathematics classroom in individual and social perspectives based on the interpretive frames of social norm, sociomathematical norm and classroom-mathematical practices then dealt with equity and identity of the students. Because Cobb contributed significantly to the development of practical theory using design experiment as the method of studies, we presented the definition, characteristics, principles, processes and practices of the design experiment. We anticipate that his ways of research would be used as means of unifying the theory and the practice in school.
