The purpose of this thesis is to study how Physical Distortion has been developed on the fashion from a surrealistic point of view and how it could be contributed to development of clothing design. This body distortion phenomenon has been started from primitivism times and it is still going on with various ways. Each era's distortion has been changed due to social cultural and environment matters. Especially influences of surrealism on the 20th century art transcended the limit of thought. Since appearance of surrealism 21th century fashion design has been opened up for new possibilities. There are no stereotypes no boundaries and our society is getting increasingly diversified. People in those society is longing to have another esthetic requirements. Also surrealistic physical distortion in the contemporary fashion has been produced unique design with new technology and new material. Physical distortion in fashion possess an infinite possibilities that could concoct the most amazing clothes. Also it has another strong potential that conducting us the way to produce design in novel ways. There is no doubt that surrealistic physical distortion in the contemporary fashion is absolute necessity to continue on evolution of clothing design.

This study aims to analyze the physical distortions of fashion design which appear in the 20th century. People have been expressing the hope and beauty by twisting human body since the beginning of mankind. Each period has been showing different forms according to various social and cultural environments. The exaggerated body distortions from the primitive times to the modern are based on human body proportions. Such distortion is to emphasize the inherent beauty within the human body. However, the distortions of the body after the 20th century have been developed with the advent of surrealism which is not affected by reasons but by imaginations. Generally speaking, the reconstruction of the heterogeneous elements is allowed in art. The unexpected surreal elements are creating formative beauty using by distinctly different technique which is unfamiliar and awkward. Physical distortion creates other beauty that is not uniform and absolute beauty but it pursues the diversity of breaking down into categories. Formativeness of surreal physical distortion fashion has the potential for a variety of clothing design, therefore it has intrinsic values for continuous study.

Purpose: The purpose of this study is to explore the importance of the image distortion correction in the cross sectional area measurement for the iliopsas muscle, tensor fasciae latae muscle, gluteus maximus muscle and the knee extensor muscles, by using (magnetic resonance imaging) MRI. Methods: This study was performed using an open 0.32T MRI system. To estimate the image distortion, T1 images for an AAPM homogeneity/linearity phantom were acquired, and the region in which the maximum geometric distortion was less than or equal to the pixel size (1.6 mm) of the images, it was defined as the distortion correction-free region. The T2 images for a human subject's pelvis and thigh in normal positions were obtained. Then, after the regions of interest in the pelvis and thigh were moved into the distortion correction-free region, T2 images for the pelvis and thigh were scanned with the same imaging parameters used in the previous T2 imaging. The cross-sectional areas were measured in the two T2 images that were obtained in the normal position, and the distortion correction-free region, as well as the area error caused by geometric image distortion was calculated. Results: The geometrical distortion is gradually increased, from the magnet center to the outer region, in axial and coronal plane. The cross-sectional area error of gluteus maximus muscle and the knee extensors was as high as 9.27% and 3.16% in before and after distortion correction, respectively. Conclusion: The cross-sectional area of the muscles that suffered from the geometrical distortion is necessary to correct for the estimation of the intervention.

Purpose: The purpose of this study was to investigate the effects of the fascia distortion model (FDM), one of the fascia treatments, on unstable ankle subjects. This was done through the chronic ankle instability tool (CAIT) questionnaire on maximum isometric muscle strength, proprioception, dynamic balance, and maximum angle. Methods: An experiment was conducted using the chronic ankle instability tool questionnaire on males and females in their twenties who suffered from ankle instability. Before the experiment, maximum isometric strength, proprioceptive, dynamic balance, and maximum angle were measured. The fascia distortion model was applied and then measurements were taken again to compare and analyze the changes. Analysis was carried out using the paired t-test. Results: After applying the fascia distortion model, maximum isometric strength, proprioceptive, dynamic balance, and maximum angle significantly improved (p<0.05). Conclusion: This study found that the fascia distortion model method was effective in improving maximum isometric strength, proprioceptive, dynamic balance, and maximum angle. The results suggest that the fascia distortion model method is a new intervention that could be used for subjects with chronic ankle instability.

To reduce the laser pulse shape distortion accompanying the amplification process and achieve an intended output pulse shape in the Nd:YAG amplifier chain, we propose a frequency-modulated pulse-amplification method. Assuming carrier-frequency-modulated seed pulses, we numerically simulate the pulse amplification in an Nd:YAG amplifier chain where severe distortion occurs. For the calculation, we develop a modified Frantz-Nodvik equation, which enables two inputs with different carrier frequencies. The simulation results indicate that the temporal contrast of the seed pulse needed to obtain a flat output pulse shape is reduced by 16 - 25 dB when frequency modulation is applied.

This paper analyzes the distortion correction of the in the micro DMD(digital micro mirror device) projector system using 0.25 or less optical throwing distance ratio. The distortion of projected image occurs depending on the performance of the optical lens, the installation location of the projection system, and the tilt of the screen. This study analyzed the physical tilt values influencing of the distortion of projected image, removed the tilt distortion of throwing distance ratio optical lens, and adjusted the distortion image by the simulation of calibration displacements. The results of this study demonstrated within 5% TV distortion reference. Moreover, the correction method reduced the pin-distortion correction of projection system.

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.

Purpose: This study sought to identify whether fascial therapy using myofascial release (MFR) and Fascial Distortion Model (FDM) techniques affected not only the area where treatment was being given but also remote areas connected to the treatment area by fascial continuity through comparison of the pain pressure threshold (PPT). Methods: The subjects were 16 healthy normal adults in their 20s and 30s who were divided into the MFR and FDM groups before the experiment. The PPT was measured at 4 different points on the body of the subjects. C7, T7, L5, and gastrocnemius along the superficial back line (SBL) before and after the intervention. Results: Only the FDM group subjects showed a significant increase in the PPT at T7 after the intervention. (p<0.05). In addition, the FDM group demonstrated significantly increased PPT at L5 compared to the MFR group. However, neither the FDM nor the MFR group showed a meaningful change in the PPT at the remote area in the lower leg. Conclusion: These findings showed that FDM can affect PPT more and has a positive effect on the pain threshold compared to MFR. However, neither FDM nor MFR showed any effect on the PPT in a remote area.

Purpose: This study compared the effectiveness of three methods, fascial distortion model (FDM), myofascial release (MFR), self-myofascial release (SMR), on the neck range of motion and pain. Methods: In this study, the collected data were processed statistically using SPSS version 22.0 for Windows. Descriptive statistics were used to analyze the general characteristics of the subjects. Repeated measure ANOVA was conducted to analyze the range of motion of the neck of the group and VAS, and Contras was used to see the difference in significance over time. One-way ANOVA was used to compare the differences among the groups and a post-hoc test was used. The significance level (${\alpha}$) was 0.05. Results: In the range of motion, the flexion and extension of the neck, right rotation, and left rotation were significantly different in the SMR, FDM, and MFR groups. The right lateral flexion showed significant differences in the FDM, MFR, and SMR groups. The VAS was similar in the groups at 2 and 4 weeks, but there was a significant difference among the FDM, MFR, and SMR groups at 6 weeks. Conclusion: In this study, MFR and MSR as well as FDM were effective in controlling the range of motion and pain control of the neck. Further studies will be needed to determine the effects of long-lasting treatments other than pain control. These studies and the present study will be used as a basis for ongoing research into the duration and method of application for musculoskeletal therapies.

The cumulative, shrinkage plastic strains and their distributions in the weld joint after completion of the welding process determine welding-induced distortion. Although the weldment undergoes many complex physical and metallurgical changes during welding, only the material plastic temperature range and its cooling history below this temperature range influence the [mal state of the cumulative shrinkage plastic strains. In addition, for structural welds, these plastic strains are uniform, except in the arc start and stop regions, along the weld. Therefore, the plastic strain-based "inherent shrinkage model" is effective and accurate to describe welding-induced distortion. This paper presents the theoretical background and numerical verification of this root cause.
