The history of foot-binding was once regarded as a unique practice accentuating the beauty of a woman and the culture of the costume, to be found nowhere except in China. This thesis makes it an aim to understand the culture of costume in China by analyzing the beauty of foot-binding, and its meanings associated with the historical background of the costume. The method of investigation was by both previous literature on the topic and case analysis. The shoes were analyzed by colors, patterns and decorations; selecting 70 pieces easily accessible in the Tianjin Huaxia Shoes Culture Museum. In terms of form, the general type was of the most frequent, followed by one with an elevated toe, mixed type, and one of the downward toe, sequentially. The color of foot-binding shoes were mostly vivid chromatic colors, while the achromatic ones like black and grey constituting significant portions. In view of the patterns, plants patterns were the most frequent, followed by the mixed patterns of mostly flowers with butterflies, bats, and birds desiring the prosperity of descendants. In view of the ornaments, embroidery was the most frequent, while the mixed shoes included tassels, sequins, applique, and shoes without ornaments were of distributions. The forms, colors, patterns and ornaments clearly associated with the wishes of artistic beauty, sexuality, and rise in women's social status may be in the hope of leading others to understand the costume culture embedded in the Chinese by providing important clues about them.

The Sample was consist of 216 female adults who were selected with my convenience from residing women in and around Seoul, Korea. The result were as fellowing; According to the factor analysis of their foot discomfort, it is divided into 3 factors: the discomfort of whole body (factor 1), the discomfort of foot sole (factor 2), and the discomfort of toes (factor 3). And the foot part of discomfort is more frequent in the order of the big toe, 2·3 metatarsal bones, and the little toe. As the age gets older, the discomfort of foot sole and toes are reported more frequently, and, particularly, more student and office employees have the discomfort of whole body while more sales women and housewives have the discomfort of foot sole. In terms of the shoe types, the higher the hill height, the more the discomfort of foot sole with wearing the sharp toe. As the wearing time is longer, the discomfort of foot sole increases. Being related to the from patterns, the broad and short type has more of the discomfort of foot sole, the flat foot feel more discomfort from the entire body and the sole. Walking with leaning toward the frontal the discomfort on toes and sole increases.

Purpose: We wanted to evaluate the relating factors for deformities of the foot after tibial fracture and the outcome of respective surgical treatment. Materials and Methods: We studied thirty-two patients (thirty-five feet) who had foot deformities after tibia fracture. The age, gender, shape, location, concurrent soft tissue injury and operative treatment of tibial fracture were analysed and outcome of the surgical treatment was investigated. Results: Deformities of the foot mostly occurred in open fractures of Gustilo type 3 or closed fracture with severe soft tissue injury. Variable surgical treatments such as simple release, lengthening, Z-plasty and osteotomy were performed. The AOFAS ankle-hind foot scale was improved from average of 37.3 points preoperatively to an average of 77.2 points at the last follow up. The Maryland foot score was from 42.9 to 90.2 and AOFAS Lesser Toe Metatarso-phalangeal interphalangeal scale was from 42.9 to 90.5. Radiological correction was also improved from 21.9 degrees to 7.9 degrees (Meary angle), from 112.2 to 138.5 (Hibb's angle) and from 33.8 to 25.9 (Calcaneal pitch). Conclusion: We proposed that great care should be taken of treatment for the tibial fracture and early detection and proper management of the foot deformities are crucial.

The purpose of this study was to determine the fundamental foot measurement data that is essential for a shoes size system of women in their 20~30s according to a survey of Korean hand-made shoes companies. This research on the current situation of shoes companies was done by interviewing and surveying employees of these companies. The subjects for this study were 407 women in their 20s~30s who lived in a metropolitan area, and who wanted to enhance their foot health and prevent injury with a proper shoes size system. They were measured with the 3D scan method in use of 6th Size Korea. The result of this study showed that there is considerable dissatisfaction related to women's shoes and the current foot size system using foot length. The Korean hand-made shoes companies assessed here did not use the KS system, but they recognized the necessity of measuring the foot width and circumference, understanding that doing so properly can decrease the return and repair rate. And current target age for shoes bye the hand-made shoes companies was reported to be approximately 5 years. There were significant results according to ANOVA, factor and cluster analyses according to the age range pertaining to the foot length, circumference and height. Each element was significantly correlated with user's satisfaction. There were 5 factors and 3 clusters represented, and foot circumstance and width were as important as foot length with a range of 5 years.

Purpose: The purpose of this study was to examine the influence of foot angles on plantar pressure and the center of pressure (COP) trajectory length during level walking. Methods: The study subjects were 30 female university students without orthopedic diseases in the foot. The foot angle was divided into three forms (out-toeing, normal, in-toeing). The subjects practiced each type of gait, and then performed each of level walking, three times, and their averages were calculated. A plantar pressure measurement instrument was used, and the maximum force was obtained by dividing the foot into nine regions covering the anterior medial-lateral, middle medial-lateral, and posterior medial-lateral. The COP trajectory length was statistically processed by obtaining medial-lateral, anterior-posterior, and entire travel distance. Results: During normal walking, the maximum force was significantly higher in the anterior lateral than in the other areas, and the COP trajectory length was significantly shorter in the front-back and entire travel distances (p<0.05). During stair climbing. Conclusion: Walking at abnormal foot angles does not cause appreciable problems in the short term as pressure is concentrated on a specific plantar part. However, it becomes the cause of deformed foot structures and can result in musculoskeletal disabilities in the long term. Therefore, a kinesiatrics-based intervention is required to maintain normal foot angles.
