손 영역 추적에서는 피부색이 가장 유용한 정보 중 하나이다. 그런데 손 영역과 얼굴 영역이 서로 겹치거나 가까이 있을 때 손 영역의 추적결과인 바운딩이 얼굴 영역까지 불필요하게 확장되는 문제점이 존재한다. 본 논문에서는 얼굴 영역 추적결과를 손 영역 추적에 사용한다. 구체적으로, 얼굴 영역 내에 손 영역의 바운딩이 침투하지 않도록 한다. 실험결과, 얼굴 영역 추적결과를 사용한 경우 그렇지 않은 경우에 비해 손 영역의 바운딩을 정확히 예측하였으며 초당 30~35 프레임의 빠른 계산속도를 유지하였다.

This study is focused on making a genuine institutional improvement from the one-sided change of the system which was implemented to guarantee student’s right to learn, and is purposed on re-align the teeth that the Article 1 of Promotion Act of School Sports(purpose) and main agents of academic sports. To accomplish this goal, the results of the study conducted on the soccer team of the middle school in ‘Y soccer specialization agency’are as follows. First, the system for guaranteeing the right to study was represented by‘unfit clothes’. Second, student athletes needed a rest. Third, main agents of school sports were worried about downgrading. Alternatives to improve this are as follows. First, we suggested rearrange of the tournament period, supplementation of e-school learning, and strict implementation of the minimum academic achievement policy system. Second, we suggested the necessity of consideration for student-athletes. Third, we suggested competitive weekend-league. Fourth, we proposed values that institutional aspects and main agents of academic sports should have.

In this paper, Position Controller for balance of Seesaw System design using PSO-PID Algorithm. When PSO Algorithm are applied for the PID parameter tuning, it is possible that the plant will be dameged due to abrupt changes in PID parameter. Seesaw System is that it's system use widely to analyze of ship or flight dynamics, Inverted Pendulum and, Robot System, manage system for theory of modern control system and all sorts of analysis. In case of Seesaw System, it's necessity that understand and analysis of system and correct selection of parameter because the system is strong nonlinear control system. It guarantees efficiency and stability to adapt quickly for disturbance or change of controller from PID Algorithm of guarantee safe from simple and long history and PSO(Particle Swarm Optimization) that sort of metaheuristic optimization that need to accuracy and fast PID parameter tuning.
