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.

The LAPS device of fast response and high sensitivity, based on electrochemical potential difference, and its system were fabricated for the precise measurement of pH changes and its characteristic were investigated. The electrostatic variation characteristics of LAPS according to the pH changes and parameters in the device were verified through a simulation using LAPS equivalent circuit model. The LAPS device and its system were fabricated on the basis of the result of simulation. The fabricated LAPS system showed linear sensitivity (about 56 mV/pH within the range of pH 2 to pH 11. In order to overcome the defect of general urea sensor (especially slow response time), urease immobilized nitrocellulose membrane was attached on the LAPS and resulted in the very fast response time, 0.29 mV/sec, 0.86 mV/sec at urea concentration of $50{\mu}g/ml,\; 500{\mu}g/ml$, respectively. And also in order to measure the uranyl ion, the uranyl ion selective sensing membrane with calix[6]arene derivative was used and its sensitivity was 25mV/concentration decade in the wide uranyl ion concentration range of $10^{-11}M\;to\;10^{-4}M$.
