In this study, a composite material frame was designed to increase the energy harvesting efficiency of polyvinylidene fluoride (PVDF) ribbon harvesters which are installed inside smart shoes. In order to minimize the amount of deformation in the load direction of the frame, it was designed using carbon continuous fiber composites and its complex shaped structure was manufactured using a 3D printer. In order to calculate the amount of deformation of the insole and midsole of the shoes under the condition of the load generated during walking, the insole and midsole were modeled using the distributed spring elements. Using finite element analysis, the elongation of ribbon-type harvesters mounted on smart shoes was calculated during walking. It is expected that the predicted elongation of the harvester can be utilized to increase the energy harvesting efficiency of smart shoes.

This study examines the impact of perceived risks for smart shoes based on purchase intention by type of smart shoes as well as how they are mediated by fashion innovativeness and technology innovativeness. It also compares the differences between awareness, interest and perceived risk of smart shoes by gender and age. This study was conducted based on men and women in their 20s to 50s who provided 246 samples for data analysis using SPSS 25.0. The results show significant differences in the awareness, interests and perceived economic risk of smart shoes by gender and age. The perceived performance risk had a positive effect on the purchase intention of smart shoes for GPS. Perceived aesthetic-psychological risk had a negative effect on all types of smart shoes. Perceived economic risk had a negative effect on the purchase intention of smart shoes for entertainment; in comparison, perceived social risk had a positive effect on the purchase intention of smart shoes for GPS and entertainment. Fashion innovativeness and technology innovativeness also mediated the relationship between perceived economic risk as well as the purchase intention of smart shoes for healthcare, GPS and entertainment.

This study examined the changes in lower body muscle activity and foot pressure during progressive squat exercise in male college students. It was conducted to help efficient exercise guidance by identifying and recognizing muscle imbalance using EMG and smart shoes and providing immediate feedback. The subjects of the study were 20 students from D University. As a result of this study, as the squat load increased, the activity of all muscles except for the left semitendinosus muscle and the anterior tibialis muscle significantly increased among. Foot pressure, when the squat load was increased, the pressure of the forefoot(FF) increased significantly and the pressure of the rear foot(RF) decreased significantly. Therefore, providing immediate feedback using a wearable device will prevent muscle imbalance and provide effective exercise guidance.

The purpose of this study was to demonstrate the effects of 8weeks Kettlebell training on the FMS and Balance in Middle school baseball player. Fourteen middle school baseball players were randomly assigned to a kettlebell group (n=8) and a control group (n=6), and kettlebell training was applied twice a week for 60 minutes. And the FMS, Y-balance test and static and dynamic balance test using smart shoes were tested before and after kettlebell training. Repeated two-way ANOVA measures was performed both before and after the exercise to verify the effect of kettlebell training. Also, if there was an interaction between time and group, a paired sample t-test was performed for each group. As a results of the study, FMS score showed a significant difference in IL (Inline Lunge) and TS(Total Score), and there was no significant difference in other variables of FMS. The YBT score showed a significant difference in all YBT variables except for the left AT. And the balance test using smart shoes, there was no significant interaction effect between group and period in all variables. In conclusion, it was found that the application of kettlebell training in middle school baseball players had an effects on the FMS and YBT scores related to functional movement and functional balance, but it did not affect the static/dynamic balance test using smart shoes evaluated by the foot pressure method. It seems that the results of this study can be provided as basic data necessary for planning a training program for middle school baseball players.

이 연구는 현 트렌드에 발맞추어 손상예방, 트레이닝 수업에 보다 양질의 피드백을 제공하여 보다 효율적이고 효과적인 교육프로그램 개선 및 개발하는데 목적이 있다. 부하가 증가될수록 우측 외측광근, 대퇴이두근과 좌측 내측광근, 대퇴이두근, 비복근이 활성도과 증가하였으며, 발의압력은 앞쪽이 증가하였으며 COG 좌/우 안정성이 감소하였다. 초보자들은 자신의 동작이 정확히 인지하고 수행하는지 어려움을 가지고 있으며 선수와 숙련자들은 강력한 근육을 바탕으로 보상작용을 수행해서 정확한 동작을 만들어 결국 근육의 불균형으로 인한 손상을 유발하기도 한다. 이러한 문제점을 웨어러블 기기를 이용하여 즉각적인 피드백을 제공할 수 있어 효율적인 운동지도를 할 수 있을 것으로 생각된다.
