According to an embodiment, a wick structure of a heat pipe that is capable of bending while increasing a heat transferring operation limit value is provided by improving the wick structure provided inside the heat pipe. The wick structure of the heat pipe includes a plurality of wicks provided inside a heat pipe, wherein the plurality of wicks include: a first wick provided at one side of a length direction to correspond to a condenser section of a heat pipe; a second wick having one side elongated to be connected to the first wick and provided at an adiabatic section of the heat pipe; and a third wick having one side connected to the other side of the second wick to correspond to an evaporator section of the heat pipe and provided at the other side in the length direction, and the first wick, the second wick and the third wick have effective pore radiuses and pore structures that are different from each other and maintain a movement and a capillary force of an working fluid supplied to the inside of the heat pipe when bending the heat pipe.

A user interface design and evaluation system and a hand-interaction-based user interface design and evaluation system are provided. The user interface design and evaluation system includes: a user interface design unit, a human model interaction design unit, a user interface prototype simulation unit, a human model simulation unit, and a user interface evaluation unit. In order to develop a user interface in consideration of usability of a user, the system provides a usability evaluation feedback system performing optimization of an interface design based on a motion simulation of a body model and user interface model. Through this, an optimum interface design is derived and by reducing the initial usage difficulty of the new interface for a user, the user can easily use the new interface and work performance of the user can be enhanced. In addition, by supporting fast prototyping and evaluation in a new product development stage, efficient production of a product having a short life cycle can be actively implemented.

An apparatus for positioning and marking a location of an electromyography (EMG) electrode includes a housing having a back surface, an EMG sensor for receiving the EMG signal, an amplifying circuit for amplifying the EMG signal to generate an amplified EMG signal and an audio output terminal for outputting the amplified EMG signal as the audio EMG signal. The examinee may directly position and mark the location of the EMG electrode and may easily detect the fatigue rate of the muscle or the abnormal condition of the muscle by using the sound of the audio equipment.
