        근골격계 부상 예방 및 활동 모니터링 케어시스템을 탑재한 스마트 신발 개발을 위한 사전 연구

        전성표(Sung Pyo Jun ),유연우(Yen Woo You),박승범(Seung Bum Park) 대한인간공학회 2018 大韓人間工學會誌 Vol.37 No.2

        Objective: The purpose is to develop smart shoes with sensors that help prevent musculoskeletal disorder of individual workers using ICT convergent technology. Background: This study intended to develop an intelligent shoe platform for analysis of musculoskeletal disorder prevention by analyzing working conditions and postures of musculoskeletal disorder, securing biomechanical database on characteristics of consumers demanding prevention of musculoskeletal disorder, and developing hardware module and platform. Method: The positions of the pressure sensors in the smart shoe were cells 3, 5, 28, 29, and 30 on the fore-foot, cells 70 and 71 on the mid-foot, and cells 83, 84, 90, and 92 on the rear-foot; the module was inserted in the rear-foot area. For the sake of weight reduction and impact absorption, injection phylon was used. Rubber materials were used for the outside of the outsole to prevent slippage. For easy insertion of the module, the vera and the eyelids on the upper were designed to be long and deep. After the shoemaking process was finished, a translucent mesh material was used for easy removal of the midsole. Results: By doing so, inserting the module became easier; the module"s accuracy and pressure dispersion improved as well. Conclusion: Working postures that induce musculoskeletal disorder can be analyzed easily by adding smart function to work shoes through existing smart devices.

        벤처기업과 기술혁신형 중소기업의 인증평가 지표에 대한 비교연구

        The purposes of this study are to find a validity of authentication index between venture company and innovative SMEs and to confirm the accuracy of authentication procedure and related authentication index. For this purpose, discriminant analysis is used to determine which variables discriminate between venture company and innovative SMEs. The results show that common factors of each SMEs have the representatives of characteristic of venture and Inno-biz, but almost other factors don`t distinguish the discrepancy between venture and Inno-biz. That is, the existing process to certify venture and Inno-biz is not effective for selecting each SMEs with sufficient innovation capability. So these authentication index should be reset and integrated to highlight the effectiveness and efficiency of authentication index between venture company and innovative SMEs. Our findings indicates that the concept of venture and Inno-biz SMEs should be clarify to differentiate the effectiveness of government`s small business corporation policy, which suggests that authentication index between venture company and innovative SMEs should be adjusted on the basis of more careful selection and focus perspectives.
