In debureing process. Human experts who have long experenc in performing deburring tasks can manipulate tools efficiently and adapt the tool motions according to the state of the process based on their skills. However, human experts have difficulties in describing linguistically their control schemes and strategies because teey don't aware the detailed process in interpreting wensory information and adapting tool motion. Therefore, it is important to develop a mean of understanding the skills and acquiring the control schemes so that the robot can perform the same skillful motion as the human experts. In this paper, an expert's skill model is developed so that it can be transferred effectively from the expertt to the robot. Skills are represented by a mapping which is generated by using a neural network. Expert's skill shows that the robot is able to associate a correct control strategy with process characteristics which is acquired from a vision image in a similar manner to a human expert's

This study presents the new method which can transfer the expert's skill to deburring robot through neural network. The expert's skill is expressed as associationmapping between the characteristics of the burr and human expert's action. Under the fundamental idea that the state of the deburring processcan be extracted via the visual sense of the human,we employ vision system for the perception and identification of the changing burr. Form the demonstration of human experts, force data are measured. Finally the characteristics of the burr and coressponding force are associated by the neural network which is trained through many demonstrations. The proposed method is verified in the deburring process of welding burr.

In this paper, we present a new approach for the automation of deburring process. An algorithm for teaching skills of a human expert to a robot manipulator is developed. This approach makes use of TSK fuzzy model that can express a highly nonlinear functional relation with small number of rules. Burr features such as height, width, area, cutting area are extracted from image processing by use of the vision system. Cutting depth, repeative number and normal cutting force are chosen as control signals representing actions of the human expert. It is verified that our processed fuzzy model can accurately express the skills of human experts for the deburring process.

Purpose - The purpose of this paper is to rationale the new approach to analysis of the human capital as a factor of effective development of a national economy and increase the level of country's competitiveness. Research design, data, and methodology - This research aims the furthest development of the conception in human capital formation. The study made on the base of the methods with scientific classification and systematization, that is, comparative, statistical analysis, economic-mathematic method, and expert assessment and ratings. Results - This research attempted to measure the correlation between the human capital elements and the level of country's competitiveness. The study revealed that formation of the competitive human capital cannot be considered in separation from the development and modernization of education system, the improvement of employment sphere, and the creation of effective interaction between them through the system of professional skills. Conclusions - The competitive human capital formation is one of the most important goals in the innovative economy construction and modern development, and it is also indispensable subject. Especially in the condition of economic crises, the necessity of formation and development of the effective human capital is considerably increasing. Realization of this task requires the development and stimulation of all the factors influencing the growing human potential.

인체의 댄스 학습은 실제로 수업을 참여하지 않고는 복잡하고 연속적인 신체 움직임으로 이루어진 전문가의 동작을 효과적으로 따라 하기는 어렵다. 본 논문에서는 인체 깊이 정보를 이용한 댄스 학습 시스템을 제안하고 있다. 제안한 시스템에서는 마커 프리 동작 갭쳐를 활용하여 댄스 전문가들로부터 다양한 예제 동작들을 갭쳐하고, 온라인 댄스 레슨에 사용하기 위해 동작 데이터베이스에 저장한다. 학생은 타블렛이나 키오스크 PC와 같은 사용자 단말기를 통해 데이터베이스에서 원하는 동작을 선택하고, 학습한 후 자신의 동작을 온라인 피드백을 받기 위해 강사에게 전송할 수 있다. 이 학습 과정에서 본 시스템은 네트워크 환경에서 학생과 강사가 효율적으로 동작 데이터를 교환하기 위해 빠르게 동작을 검색할 수 있는 방법과 다중 모드 화면을 제공한다. 실험 결과에 따르면 본 시스템은 학생들의 댄스 스킬을 주어진 시간 안에 향상시킬 수 있다.
