This study explored demographic characteristics based everyday lifestyle patterns and preferred spatial requirements of potential collective housing residents in Korea who would pursue ‘Ambient Assisted Living’ with ‘Aging In Place’ initiatives. Online questionnaire survey was commissioned for the pre-elderly and elderly age groups of 40s, 50s and above 60s, 801 individuals in total. Survey participants were asked to select 3 most preferred answers among 5 with ranked priority to clearly capture each testee’s true priority choices over 50 carefully designed questions in relation with promoting healthcare sensitive residential spaces. Comprehensive analysis was carried out by processing the survey results with cross-tabulation analysis. The outcome showed fairy unanimous preference patterns across majority of the questions regardless of gender, age, and economic status differences. Formation of separate and independent household, relatively spacious living room, possible layout alteration after moving into a residence, non-slippery bathroom floor, bio-medic sensor embedded chair or sofa were identified as those commonly preferred requirements of physical space design for an household. Some subject groups such as female and age group of over 60s show similar preference profile in the sense that both groups prefer living in the same collective residence when they are aged, cooking ordor ventilating kitchen, bed with storage below, ventilation for kitchen and bathroom. This implies certain demographic groups share their residential preference when aging is in progress. Differentiated residential preference profiles among different demographic groups were also identified. For instance, male, age groups of 50s and over 60s, low-income group prefer living in a same household whereas female, age group of 40s and high-income group turn out to prefer living in a separate household in the same collective housing complex when they are aged. While most of testees prefer garden farming for their apartment veranda, age group of 40s and high-income group express their preference of using veranda as a resting place. Comprehensive analysis on those preference profiles across major demographic classification was summarized in table format focused on healthcare sensitive household unit design. This study is a pioneering attempt to identify a set of preferred health-sensitive lifestyles and residential space requirements to be insightful for planning and designing ‘active aging in place’ supportive collective housing household units in Korean context.

본 연구에서는 대표적인 폐기물 최종 처리시설인 소각장을 대상으로 소각열 회수에 따른 경제성 분석을 수행하였다. 국내에서 운영 중인 소각장의 건설 및 운영비용, 소각열 회수량에 대한 함수식을 회귀분석을 통해 도출하였으며, 이를 바탕으로 생애주기비용을 비교함으로써 소각열 회수에 대한 경제성을 비교 분석하였다. 도출된 회귀식으로 일일 80톤 처리규모의 소각장을 기준으로 경제성 분석을 진행한 결과, 소각열 회수시 추가 설비 및 인건비로 인한 초기투자 비용 및 운영비용이 크지만, 열회수에 따른 LNG 대체효과로 계산시 11년 이상 운영할 경우 미회수 소각장과 비교하여 경제적 우위성이 있었다. 또한 열 판매와 온실가스 감축효과를 편익으로 계산할 경우 19년의 자본회수기간이 소요됨을 확인하였다. This study aims at providing an economic assessment for incineration plants which recover heat during its incineration process. In this study, Life Cycle Cost(LCC) of incineration plants is performed based on each regression analysis formula for construction cost, operation cost, and heat generation in order to compare economic feasibility. The result shows that the incineration plant recovering waste heat while processing 80 tons of waste per day increases both initial investment and operation cost but this type of an incineration plant has economical predominance from the recovered waste heat over the one that does not recover heat when being operated for more than eleven years if the retrieved heat replaces the use of LNG. And its payback time reaches more than 19 years in case of selling heat and performing emission trading.

'그림'은 대상간의 상호소통을 위한 직관적인 방법이다. 사물의 모습이나 추상적인 개념을 2차원 공간에 그려서 의사를 전달하는 일은 대상의 특징에 대해 사회적 합의를 통한 고차원의 통념적 해석을 요구하는 언어학적 관점에 있어 문자기호 이전의 최하위 수준 인간중심적 언어이다. 본 연구에서는 사용자의 직관과 감성을 자극하는 인터페이스 요소의 요구에 대응하여 점차 지능화되는 디지털 매체와 사용자간의 인터랙션을 보편화된 인간중심적 관점으로 접근해 '그림'기호의 통념적 해석이론을 정립하고 HCI 요소로 활용하기 위한 방법론을 제시한다. 이를 통해 디지털 미디어 공간을 구현하여 사용자에게 새로운 경험을 제공함으로서 감성을 자극하고 그 효과를 검증한다. 'Scribble' for interactions between the target is an intuitive way. The appearance of things or abstract concepts by drawing on two-dimensional space, communicating what the social consensus about the nature of the target through the high-level linguistic terms that require interpretation tongnyeomjeok a letter to the lowest level of the previous symbol is a human-centric language . In this study, to stimulate your intuition and emotional response to the growing needs of interface elements, digital media and user intelligent interactions between hwadoeneun pervasive human-centric approach in terms 'picture' theory formulation and interpretation of symbols HCI elements tongnyeomjeok presents a methodology for taking advantage. Through which to implement the digital media space by providing new experiences to stimulate the senses and to verify its effectiveness.
