The purpose of this study is to empirically analyze whether open innovation activities are significant and which methods are more effective in developing new businesses. Based on the latest technological innovation survey data of the Science and Technology Policy Institute, the results were analyzed by binary logistic regression analysis. As a result of the analysis, we confirmed that open innovation activities have a positive effect on the performance of developing new businesses. In the open innovation activities, Recruitment (invitation) of specialist in related fields, Business alliance technical agreement, Dispatch of personnel, M&A, Acquisitions identify related field trends showed more influence in order. It would be beneficial to improve the performance of developing new businesses with a low probability of success if utilize more effective innovation activities in developing new business in enterprises or organizations throughout this study.

The above-Knee Prosthesis has been used by the handicapped person and become a important part of their life. But uniform above-knee prosthesis only increases inconvenience And so the tool that can estimate and help to design of suitable prosthesis for user need to be developed. The simulator developed in this research is composed of two part. One is hardware that can realize various walking motions. The other is software that can display and analyze the results of walking mot ion. Three motors constitute hardware of Simulator. Two motors are used to realize heap motion that need two degree of freedom and the rest one used to realize swing motion. Software of Simulator display results of three motor trajectories and walking mot ion of hardware using computer graphic. Therefore, The simulator developed in this research which is able to realize human gait and results are analyzed through simulation program at PC will be some help to design and produce of prosthesis suitable to user.

We made a human-sensitive motion interpretation to the interactive emotional robot, "Rai" of which the mechanism design was carried out and completed. Kinematic system of this emotional robot mainly consists of a body and a head. The body contains the total control units , the communicat ion modules and also two wheels and motors for main driving which make kinds of motions 1 ike the inverted pendulum. This robot system is designed under the concept on the human-friendly mot ion and react ion wi th humans around living room and office environments. Therefore, various scenarios are constructed in order to enable the emotional expressions at those places. Especially, we interpreted technically-possible motions while accommodating to the scenarios constructed. And we performed some experiments to make sere of the possibility of the motion interpretation.

The variable of WRL is composed of dimensions and their sub-items based on FRL. This study categorized these dimensions into 43 items fittingly to the situation in Korea through examining the validity of the contents. In addition, to overcome limitations in situation set for formulating the variable, which was not suggested in previous researches, this study diagramed the situation in three steps based on the cycle of MOT. The index of WRL which was adapted to reality of Korea society was finalized into 8 dimensions and 33 questionnaire items after processed in refining method as a procedure of re-proving the method.

Linear motor can directly apply to the system needed linear mot ions without rotary mot ions. To control a high-speed and high-resolution, the development of the linear motors is recently required in the high-integrated and speed process industry. This paper presents vibration analyses as well as measurement standards of the newly developed linear motors through analyzing the vibration characteristics and thermal behaviors of the advanced products. Vibration experiments are conducted for identifying the hysteresis and vibration level during operation. They are also included in the modal test to analyze the vibration. Analytic data using Finite Element Method (FEM) are compared with the results of the modal. Loss of temperature generated the linear motor leads to a serious deformation within its parts. The thermal behaviors are very important factor in linear motor. The FEM and experiments make it possible to understand these characteristics.
