Autor: Seung-Bok Choi, Xuan Phu Do, Ae-Ri Cha, Nguyen Quoc Hung, Long Mai Bui Quoc

Publikováno v: Sensors and Smart Structures Technologies for Civil, Mechanical, and Aerospace Systems 2018.

In this paper, an exoskeleton for human knee is proposed. This design is based on the magnetorheological (MR) fluid theory and its application on vibration damper. The damper is analyzed and developed to suit the human motion. The motor torque is opt

Design of new prosthetic leg damper for above knee amputees using a magnetorheological damper activated permanent magnet only

Autor: Tae-Hoon Lee, Seung-Bok Choi, Ji-Young Yoon, Ae-Ri Cha

Publikováno v: Active and Passive Smart Structures and Integrated Systems XII.

Magnetorhological fluids (MR) have been applied to numerous devices or systems which require forward or feedback control to achieve desired performances. One of applications is the rehabilitation device. MR dampers applied to artificial joints are im

n-3 Polyunsaturated Fatty Acids and Atopy in Korean Preschoolers

Autor: Tae-Ho Yoon, Byung-Mann Cho, Yongsoon Park, Ae-Ri Cha, Hyejung Yoon, Hyo-Sun Lee, In-Kyung Hwang, Su-Ill Lee

Publikováno v: Lipids. 42:345-349

Atopy is a growing problem for Korean children. Since eicosapentaenoic acid is a precursor of less active inflammatory eicosanoids, n-3 polyunsaturated fatty acids (PUFA) may have a protective effect on atopy. This study was undertaken to determine w
