To address threats to the natural environment, the government in Pakistan has banned the use of plastic bags for shopping. The concept of governmentality presented by Michel Foucault explores the techniques of governance and defines law not just as the manifestation of sovereign power but also as a technique of governance involving a range of organized practices designed to shape mentalities to achieve certain desired ends in subjects which claim to be for the welfare of the population. The present study explores the perceptions of the consumers regarding the rationality of the government behind the ban and also highlights the effectiveness of the use of law as a technique of governance. A qualitative approach was used by conducting fifteen interviews with young consumers selected through convenience sampling. The findings suggest that the rationality of the government behind the ban was received well by the consumers and the ban was viewed as a positive and pro-environmental step. The use of law as a technique of governance also proved to be effective in the said case because the people did not perceive the law as coercive despite the radical change it brought to their shopping practices. The present study contributes to the development of the theoretical understanding of governmentality and its sub-concept of the use of law as a technique of governance.

$F{\theta}$ 렌즈는 레이저 프린터의 LSU(Laser Scanning Unit)의 중요 부품으로서 $F{\theta}$ 렌즈를 통과한 주사빔의 상 위치는 주사빔의 렌즈 입사각에 비례한다. 본 논문에서는 당사에서 개발한 A4 사이즈용 $F{\theta}$ 렌즈를 설계, 제작하고 보정하는 과정을 소개하였다. 렌즈 개발에서 광학설계는 Zemax를 사용하였고 주사빔의 주주사방향 및 부주사방향의 왜곡을 최소화 하기 위하여 렌즈면은 특수한 토릭면으로 하였다. 렌즈 금형은 1nm 의 분해능을 갖는 초정밀 가공기로 제작하였다. 렌즈 사출 후 성능을 평가하고 측정값과 설계값의 차이를 바탕으로 설계보정식을 유도하여 렌즈 금형을 수정하였다. 금형 수정 후 사출렌즈의 재측정 결과 초기 설계값에 가까운 성능을 확인하였다.
