This study is aims to study the background of how the shape of the wooden shoes developed and worn by Koreans and Japanese in the ancient times by sorting and examining the types and shapes. Relevant bibliography, which are mainly related to the excavated wooden shoes from 3 B.C.E to C.E. 8., were used as research materials. The formation of wooden shoes required easy access to raw materials -which is trees- for production. According to the analysis, both Korea and Japan made the flat wooden shoes using cuboid wood. Both countries bore a hole on a specific location to distinguish the right foot and left foot, however the style of the heel was different in the two countries. The slip-on(Undu-hyeong) wooden shoes were also common in both countries. The slip-on had no-heels and was made by digging-out a piece of the cuboid wood. Some slip-ons made by the Japanese had furrows on the bottom, and they were known to make different types of the slip-on wooden shoes depending on the purpose. Observation of the wearing methods show that commonality can be found between the wooden shoes of Korea and Japan, and this indicates that cultural exchanges between the Silla/Baekje and Japan took place from the 4th to the 6th century. Also, the flat wooden shoes in Japan developed rapidly, as the shoes became an integral part of its life and culture, which was closely tied to agriculture. Eventually, due to the difference in climate and life-style, the slip-ons became the primary type of wooden shoes in Korea, while the flats became the main type of wooden shoes in Japan. It is, however, clear that as the relationship between the two countries became closer, the cultural exchanges regarding the wooden shoes were considerable.

Purpose: The purpose of this study was to investigate the effect of microcurrent on fatigue of muscles in people who were flat-footed during gait. Methods: 10 flat-footed university students volunteered to participate in this study. 10 flat-footed subjects were divided into 2 groups, one group was experimental group of 5subjects(This group put on microcurrent induction shoes but the subjects were not able to feel the current.) and the other group was the control group of 5subjects(This group put on the general shoes which were similar in shape but microcurrent was not induced.) to perform double blind test and random sampling. Their gait muscle fatigue of 6 regions (vastus medialis, gastrocnemius, tibialis anterior, biceps femoris, erector spinae, and rectus abdominis muscle.) was measured by EMG MP150, Delsys Inc Boston, USA during walking and then they carried out the Harvard step with a platform (It was a arbitrarily made wooden platform of 100cm long, 50cm wide, 60cm high. They carried out climbing it for one second and descending it for one second by using the Metronome program, total 5minutes) for 5minutes. Right after that, the subjects walked on a treadmill at a speed of 4km/h for 10minutes and then their gait muscle fatigue of 6regions was assessed while they were walking on the ground as equally as before exercise. Results: The experimental group has resulted in lower average differences in gait muscle fatigue before and after exercise than those of the control group average 12.24Hz(P=0.009) at vastus medialis, average 8.52Hz(P=0.016) at gastrocnemius, average 9.16Hz(P=0.009) at tibialis anterior, average 8.66Hz(P=0.047) at biceps femoris, average 7.53Hz(P=0.016) at erector spinae, and average 7.80Hz(P=0.047) at rectus abdominis. All of the assessments of muscles have shown significant difference statistically. Conclusions: This result has shown that the use of micro current could decrease gait muscle fatigue of flat-footed people. It is recommended to use a microcurrent to reduce their gait muscle fatigue.
