This paper is a study on the implementation of smart filter system that recognizes the external environment and automatically removes pollutants according to pollution level. Recently, the occurrence of various pollutants in indoor and outdoor space has adversely affected the human body. Especially, various fine dust generated in the atmosphere becomes worse in closed residential space or office space. Although air pollution can be temporary lowered through ventilation, it is difficult to respond to fine dust changes in real time, and such problems become serious in the space where many people reside, such as at home or industry. Therefore, it is necessary to measure the pollution level of fine dust inside the residential space in real time and to reduce the pollution of indoor ventilation through automatic ventilation with the outside. To improve these problems, this paper proposes the implementation of smart filter system for external environment recognition. The structure of smart filter system that automatically measures air quality inside and outside, removes pollutants, implements the function, and confirms the operability by manufacturing prototypes. Finally, the effectiveness of the smart filter system for solving fine dust problems was examined.

Gentrification, caused by residents who are being forced out due to the rise of rent with vitalization by an excessive increase of city tourists and Touristification, meaning of phenomenon of residents' migration caused by residential area turning into tourist attraction have recently pointed out as a global problem. In Korea, the phenomenon such as environmental pollution, the rise of land value and rent, and the weakening of community culture in Jeju island and Bukchon Hanok Village has appeared as well. This phenomenon has become a serious problem by hindering resident's quality of life. In this circumstance, Smart tourism city has been regarded as a solution of these problems. Hence, this study chose Busan city, which has been designated as a smart city since 2015, and examined the complex impacts of the economic benefits, social costs, environmental substantiality, cultural benefits, and technical effects derived from tourism development on the residents' deteriorated quality of life based on Fuzzy-set Qualitative Analysis (fsQCA). As a result, three patterns of the hindrance to residents' quality of life were derived. If social costs of tourism development are perceived to be large, the residents perceive deteriorated quality of life, even if they recognize essential benefits (technological and economic benefits) (Pattern #1) or secondary benefits (environmental and cultural benefits) (Pattern #2) of tourism development. In addition, some residents were found not to recognize any benefits of tourism development (Pattern #3).

The resulting rapid urbanization in the several decades caused increasing residential mobility. The purpose of this study is to analyse systematically the effects of residential mobility on the family quality of life and the factors that cause residential mobility. For this purpose, 976 housewives were sampled from the households in Seoul. The data were analysed by such statistical methods as multiple regression, crosstabulation, ANOVA test and path analysis. The main results obtained are as follows; 1) A significant proportion of the urban households are experienced frequent residential mobility. 2) Among the factors that affect residential mobility, the most important factors are family income, tenure type, and residential satisfaction. 3) Residential satisfaction is an important intervening variable in residential mobility. 4) It has been observed that family quality of life was affected by residential mobility patterns. Analysis has revealed that quality of life de eloped remarkably by changing for residential location, especially in education environment for their children.

기존 가시권 분석에 있어서는 주거지 개발, 도로, 송전선 설치 등에 따른 시각적 영향을 분석하는 연구가 많이 이뤄졌다. 이들은 개발에 따른 시각적 영향을 분석하고 부정적 영향을 최소화시킴을 목표로 하고 있다. 경관이 안공요소의 침입을 수용할 수 있는 정도를 고려하여 각 경관의 수용능력에 따른 개발을 유도함으로써 시각적 환경의 질을 높이고자 하는 것이다. 또한 도심지의 개발로 인하여 중요 문화ㆍ관광자원의 훼손으로 오랫동안 잘 보존되어야할 관광자원에 대한 시각적 영향을 분석하고자 하였다. 본 논문에서는 많은 문화ㆍ관광자원을 보유하고 있는 경주시 지역에 대하여 가시권역을 시각화하고 분석하여 보았다. 우선 경주시 지역에 대한 1:25,000 수치지형도 9장을 중첩하여 Arcview 프로그램을 이용하여 등고선만을 추출하였으며, 추출된 등고선도를 가지고 DEM을 생성한 후 Arc/GIS의 Workstation Arc/Info를 이용하여 가시권역을 나타내어 보았다. 이렇게 나타난 가시권역과 문화ㆍ관광지역과의 중첩을 통하여 가시지역의 범위를 분석하여 본 결과 관측점에서의 가시범위가 약 70%정도로 나타났다.

본 논문에서는 한국노동연구원에서 1998년에 수집한 "한국노동패널조사" 자료를 이용하여 소득과 만족도로 측정된 주관적 삶의 질간의 관계를 집중적으로 검토해 보았다. 가구 소득, 가족 관계, 여가활동, 주거활동, 근로활동의 5개 삶의 개별영역들에 대한 만족도가 전반적인 삶의 만족도의 50% 이상을 설명되며, 수입에 대한 만족과 전반적 만족간에는 체감의 관계가 있는 것을 발견하였다. 우리 나라 사람들은 자신의 생활에 보통 이하의 만족을 느끼고 있다고 보고하고 있다. 실제 소득과 소득만족도 와 의 연관 은 그렇게 크지 않으며, 이는 가구 소득의 경우에나 개인 소득의 경우에나 유사하게 실제 소득이 소득만족도의 10%정도의 변이만을 설명하고 있다. 서구의 연구 결과와 유사하게 모두 외적인 조건들을 생활만족도의 설명변수로 한 희귀 분석 결과는 변량의 10%정도만을 설명할 뿐인 것으로 나타난다. 것으로 나타난다.
