본 연구는 빛공해 및 환경요인이 박새의 새벽 울음 시간에 미치는 영향을 밝히는데 목적이 있다. 연구대상지는 빛공해지역은 원주시 상지대학교 캠퍼스를 자연지역은 치악산국립공원 서측 산림으로 선정하였다. 녹음기간은 2014년 3월 26일에서 5월 30일이었다. 빛공해에 따른 새벽 울음 시작 시간을 분석한 결과 빛공해지역이 자연지역보다 먼저 울음을 시작하는 경향이 뚜렷하였다(p<0.05). 박새는 주로 일출 전에 첫 울음을 시작하였는데, 대부분의 조사일에서 상지대학교의 박새가 먼저 울기 시작하였다. 이로 인해 암컷이 미성숙한 수컷과 교미할 확률이 높아지고, 적정 번식기보다 일찍 새끼가 부화함으로 해서 먹이자원이 부족할 가능성이 높을 것으로 판단되었다. 환경요인에 의한 영향은 일출시간, 시민박명, 항해박명, 천문박명, 평균온도, 최고온도, 최저온도, 월출시간, 운량과 박새의 새벽 울음소리와의 상관관계를 분석하였다. 야생조류 울음 시작시간은 월출시간과 운량을 제외한 모든 환경요인의 상관관계가 인정되었다. 박새는 일출시작 이전에 날이 밝아지기 시작하는 시민박명 전후에 첫 울음을 시작하였고, 일출시간과 대기 온도가 상승함에 따라 새벽 울음 시작시간도 앞당겨졌다. 월출시간과 운량은 상관관계가 인정되지 않았는데 이에 대해서는 추가적인 연구가 필요하다.
Environmental lighting zone-setting has suggested regulatory standards according to the influence of artificial illumination on natural environment and human life. Then, it is necessary to check out the viability of environmental lighting zone division as it is limited to use-zone division. This study aims to suggest some problems, which occur when environmental lighting zone is set by use-zone only, by comparing and analyzing the artificial illumination luminance. In addition, this study aims to suggest basis for the environmental lighting zone-setting and eventually, more effective environmental lighting zone division.

In his non-hierarchical approach to art making, Robert Irwin questions how art is made. In the process, he seems to come down on both sides of the Modernism versus Postmodernism debate. Insofar as he wants to advance the avant‐garde tenets of modern art, he can be thought of as a modernist. But insofar as he denies Modernism’s claims for transcendental status, he can be thought of as a postmodernist. Irwin’s light and space environments, in particular, are conditioned by their basic attachments to their surroundings. They reveal the commonplace, but largely overlooked, richness of visual perception. By encouraging his viewers to open their eyes, Irwin wants them to engage in an act of looking, one that manipulates the basic syntax of seeing. This paper discusses Irwin’s contributions to the art of his time (basically the transitional period between Abstract Expressionism and Minimalism) using as an example a light and space environment he created as the backdrop for the “First National Symposium on Habitability.” This work was later reprised in 1980 as an independent installation. These works are examined to show how Irwin’s art displaces modernist notions of authoritative (and authoritarian) quality with postmodernist ideas of direct (and demotic) value.
