Objective: This study compared the effects of streamlined shoes on dynamic gait and foot plantar pressure in healthy young adults. Background: With the importance of ankle and lower extremity mechanism, streamlined shoes are contributing to a static gait factors. However, the study of dynamic gait factor is still insufficient. Method: Sixty subjects were randomly allocated to two groups: experimental group(n=30) and control(n=30), respectively. The experimental group performed streamlined shoes, whereas the control group applied usual shoes. Main outcome measurements were assessed contact time, step length and foot plantar pressure using gait analysis with the treadmill. Independent t-test was used to compare the both groups. Results: Compared with control group, contact time of forefoot, midfoot and hindfoot decreased significantly in experimental group(p<.05), Step length increased significantly in experimental group(p<.05). Foot plantar pressure of midfoot and hindfoot increased significantly in experimental group(p<.05), whereas that of forefoot did not show significantly in experimental group(p>.05). Conclusion: Our findings suggest that streamlined shoes was more effective than usual shoes in dynamic gait change including contact time and step length and foot plantar pressure in healthy young adults. Application: The results of streamlined shoes might help to control for the gait of industrial workers.

This study focuses on Korea's traditional-style soryebok, in terms of its foundation, progression, and structural features. The research methods employed here include literature analyses of relevant laws and an official daily gazette, and practical analyses of artifacts and photographic documents. Especially, the artifacts of heukdannyeong(black uniform for officials with a round neck) in the form of chaksu(tight sleeves) were examined, which was regulated as soryebok in Eulmiuijegaehyeok. The term "soryebok" firstly appeared in "使和記略"(Sahwagiryak) written by Park Yeong-hyo, a foreign envoy to Japan, in 1882. Emperor's invitation written in the book asked him to wear daeryebok at the ritual and soryebok to the banquet. Soryebok was not adopted in Gapshinuijegaehyeok in 1884. However, several illustrated documents of the modern banquets at that time reveal that sabok, which was included in the 1884 reform, was used as soryebok. According to the Gapouijegaehyeok in December 1894, courtiers were required to wear heukdannyeong as daeryebok, and add juui(topcoat) and dapho(sleeveless coat) as tongsangyebok when they visited the royal palace. In Joseon's first daeryebok system, the term "tongsangyebok" that had been used in Japan was employed before soryebok was used. According to Eulmiuijegaehyeok in August 1895, the term "soryebok" originated from a costume ritual for courtiers of the Joseon Dynasty. Soryebok featured heokbannyeong chaksupo, samo (winged hat for officials), sokdae(belt), and hwaja (shoes for officials). There are around 24 artifact pieces of heukdannyeong in the form of chaksu(tight sleeves) in the following locations: garments of Prince Heungwangun and Wansungun, the court artifacts, Korea University Museum, Yun Ung-ryeol's family housed at Yonsei University, and Kyungwoon Museum. Artifacts have mu(godet) pulled back and a topcoat-like triangular mu. In conclusion, heukdannyeong, traditional-style soryebok has significance in the history of modern dress because streamlined traditional clothes and newly introduced Western dress system were able to be combined.
