To provide context aware service, certain phenomena and situation information of the user should be detecting and monitoring using sensors. But, the sensor data has heterogeneity about system, syntax, structure, and semantics. So, it is difficult to apply to various services. To solve this issue, we should remove these heterogeneities and convert to context information that is easy to provide context aware services. Also, the existing context aware service mash-up environment require relevant sensor type, criteria of context, programing ability to define the service situation. So, it is difficult to create service for a non-technical user. Therefore, we propose ontology based user-centric service environment to provide context aware IoT services. It provide context awareness and user-desired services using data that acquired via IoT paradigm. The proposed environment consist of the ontology based semantic sensor data processing and the user-centric service environment. It provide convert the object data to the context information and service mash-up process to create user service in easy way.

폴리비닐알코올 (poly(vinyl alcohol), PVA)는 분해되어 대부분의 성분이 물과 이산화탄소로 전환되는 가장 이상적인 환경친화성 고분자이다. PVA만의 특유한 반응인 비누화 과정에 의해 가지가 모두 제거되기 때문에 화학적인 방법에 의해 완벽한 선형고분자를 얻는 것이 가능하다. PVA는 측쇄에 존재하는 히드록시기의 강력한 수소결합 때문에 우수한 반응성 및 결합성을 보유한 유기 고분자로서, 수용성 뿐 아니라 다양한 소재와 상용성이 있는 것으로 알려져 있다(1-4). (중략)

생활수준 향상과 주 40시간 근무제 도입등에 따라 해양성 휴양 및 관광 수요는 증가하고 있으나 이를 수용할 수 있는 어항 기반은 매우 취약한 편이다. 다양한 관광수요를 만족시키는 환경친화적 관광기능어항 개발이 절실한 실정인 것이다.

21세기에는 항공여객의 수송 수요가 비약적으로 증가할 것으로 예측되고 있다. 수요의 한쪽은 수송의 대형화이며 다른 한쪽은 수송의 고속화이다. 이런 수요를 충족하기 위해서는 경제성과 환경친화성을 겸비한 차세대 수송기 개발이 오래전부터 요망되어 항공기 제조 선진 각국은 한걸음 한걸음 이들 수요에 부응할 신종항공기의 개발을 추진중에 있다.

The energy efficiency and environment-friendly aspect of the railway system would be superior to other on-land transportation systems. In a preliminary feasibility study stage and selection of optimal railway corridor, the energy efficiency and problems related to environment are usually not considered. For the selection of optimal railway corridor, geographical features and facility of management are generally considered. Environment effect factors for the selection of environment-friendly railway corridor are focused and studied in this paper. In this study, various analysis of opinion of specialists (railway, environment, transport, urban planning, survey) and the guideline for construction of environment-friendly railway were accomplished. From these results of various analysis, 7 major categories (topography/geology, flora and fauna, Nature Property, air quality, water quality, noise/vibration, visual impact/cultural assets) were extracted. To select environment friendly railway corridors, many alternatives should be compared optimal corridor must be selected by a comprehensive assessment considering these 7 categories. The investment for railway systems can be encouraged by the considering of main environmental effect factor evaluated with the modified environmental weight factors for environment-friendly railway construction.

In the COVID-19 crisis, the elderly over 60 have various psychological health problems such as depression, anxiety, and fear, and the community has become the only space for senior activities. To this end, this study presented a therapeutic aging-friendly community environmental design evaluation system using theoretical review, FGI interview, and hierarchical analysis AHP. The evaluation system is a three-dimensional space, with 10 upper layers and 68 lower layers. In addition, the weight of each index of the evaluation system was distributed through expert survey and SPSS program analysis. First, the material space environment design must satisfy the comfort and health of the elderly when they are active in a common space for their daily life. Second, the design of social space environment is designed to promote exchange and social connection among the elderly. Third, the operating space environment design considers the operating system of the community operating company as important. Through this, it is expected to improve the psychological health of the elderly by providing systematic technical basis and action guidelines for the development of the residential environment of the elderly.
