In this study, we analyzed the state of outdoor-space use and green-environment development for apartment residents, and investigated their ways of thinking on nature orientation and green environment. The results are as follows. 1) The ways of thinking and actual use of outdoor space by apartment residents appear different. 2) Due to the difference of apartment locations and complex environments, the state and reason of green environment construction are different between the residents of high-rise and low-storied apartments. 3) The residents of the low-storied apartments are more satisfied with the green environments of the complex than those of the high-rise apartments. In addition, constructing the green environment in a balcony and outdoor space enhances the satisfaction level of the apartment residents. 4) The residents of the low-storied apartments are passive in nature orientation, while those of the high-rise apartments are active. 5) Depending on the types of nature orientation, the apartment residents are grouped as 'people of nature experience', 'nature appreciators', or 'people of living-thing contact'. These groups show different patterns on the ways of thinking for outdoor space and green environment.

This paper is to clarify a cognitive structure of green environment in the traditional urban residential areas. The following is the result of analysis; 1) According to the survey of created actual condition of the green environment, the main space was consisted of court(74%). The percentage of preference locations for green environment at the court and the alley are 71, 60 respectively. The main reason to creat green environment resulted admiration and enjoyment. 2) The degree of $\ulcorner$agreeableness$\lrcorner$ and $\ulcorner$nobleness$\lrcorner$ of the house were increased by creating green environment in a house, and the degree of $\ulcorner$neighborhood$\lrcorner$ and $\ulcorner$familarity$\lrcorner$ were increased by creating green environment out side of house. 3) According to the analysis of a correlation between the degree of satisfaction and the image, $\ulcorner$agreeableness$\lrcorner$ has an interrelation with all factors of image. Therefore, the creating of $\ulcorner$agreeableness$\lrcorner$ is a main problem for raising the whole image of the residential areas.

pH변화를 정밀하게 측정하기 위하여 빠른 응답특성과 높은 감도를 갖는 전기화학적 전위차를 이용한 LAPS(Light-Addressable Potentiometric Sensor) 소자 및 시스템을 제작하여 그 기초 특성을 조사하였다. 먼저 pH 변화에 따른 LAPS의 정전기적 인 변화특성 및 소자의 변수를 LAPS 등가회로 모델을 이용한 모의실험을 통해 검증하고 이러한 모의 실험을 바탕으로 하여 LAPS 소자 및 시스템을 제작하였다. 제작된 LAPS 시스템은 pH 2-11 사이에서 56 mV/pH의 선형적인 감도를 보였다. 구성된 LAPS 시스템의 다양한 응용성을 도모하기 위한 시도로서 먼저, 일반적인 urea 센서가 가지는 긴 응답시간의 단점을 극복하기 위해 nitrocellulose membrane 에 urease가 고정화된 막을 LAPS에 부착하여 측정한 결과 urease 농도 $50{\mu}g/ml,500{\mu}g/ml$에 대하여 각각 0.29mV/sec, 0.816 mV/sec의 매우빠른 응답특성을 얻을 수 있었다. 또한 환경적 측면에서 중요한 우라닐 이온의 감지를 위하여 우라늄 인식 매체를 LAPS의 감지부에 부착하고 수용액 속에 녹아 있는 우라늄 이온을 측정한 결과 $10^{-11}\~10^{-4}M$의 넓은 농도 범위에서 25mV/decade 감도를 보였다
