The economic theory of criminal behavior predicts that the returns to legitimate activities are a primary determinant of the amount of crime. An increase in the returns to legitimate activities decreases the profitability of criminal acts because forgone income if imprisoned is part of the expected cost of committing criminal acts. Increase in returns to legitimate activity therefore result in a decrease in amount of crime. This decrease in the amount is reinforced by the substitution away from criminal acts toward legitimate activities due to the increase in the relative returns to legitimate activities. Economic conditions, particularly labor market conditions and income, largely determine the returns to legitimate work effort. Labor market conditions determine present expected earnings from legal work. Because economic conditions largely determine the returns to legitimate activities, and the returns to legitimate activities substantially affect the amount of crime, the economic theory of criminal behavior predicts that there is a significant relationship between economic conditions and the amount of crime. Increase in the unemployment rate (decrease in the rate of economic growth) are predicted to be associated with increase in the amount of crime ; conversely, decrease in the unemployment rate (increase in the rate of economic growth) are predicted to be associated with decrease in the amount of crime. This paper is a study about correlation between economic conditions and property crimes with crime-economic theory. The theory and empirical research concerning the relationship between economic conditions and crimes are reviewed. The testing and analysis of correlation between rate of economic growth and property crimes with SPSS package program are tried. Data of rate of economic growth(from 1973 to 2003 year) and property crirneststolen goods crime, fraud, embezzlement, breach of trust, robbery, blackmail) is used. 본 연구는 경기변동과 같이 경제적 환경이 변화함에 따라 각 개인들(또는 범죄인들)의 의사결정에 어떠한 변화가 발생하고 결과적으로 이러한 결과가 범죄실행에 긍정적 측면, 또는 부정적 측면을 부각시키는지를 분석해보고자 한다. 특히, 경기변동이나 실업률 변화에 따른 범죄율 변화에 대한 기존 연구결과들을 검토하고 주제와 관련하여 경제이론적 측면에서의 고찰하며, SPSS 통계패키지 프로그램을 이용하여 경제성장률과 범죄율의 상관분석을 검증하였다. 계량적 검증을 위한 기초자료는 1973년부터 2003년 까지의 경제성장율, 범죄율을 대상으로 수집하였다. 범죄율의 경우 범죄유발 동기효과 측면을 부각시키기 위하여 財産犯罪를 주 대상으로 자료수집 하였다(장물, 사기, 횡령, 배임, 강도, 공갈 등).

When a robot is to have contact with its enviornment, such as a medi-care robot, it would be advantageous for the robot to have a high compliance. For this reason, a robot having not only a flexible link but also an actuator with compliance, is desirable. This paper is concerned with the position and vibration control of 1 degree of freedom flexible robot using a pneumatic artificial muscle actuator. The dynamics of the manipulator assumed to be and Euler-Bernoulli beam are derived on the basis of the linear mathematical modle. Although this pneumatic artifical muscle actuator has many merits for the compliance robot, it is difficult to make an effective control scheme of this system because of ths nonlinearity and uncertainty on the dynamics of the actuator. By designing a controller using .mu.-synthesis, robust performance against measurement noise, various modeling uncertainties on the dynamics of the servo valve, actuator and mainpulator, is achieved. The effectiveness of the proposed control method is illustrated through simulations and experiments.
