In this paper, With the development of modern science and technology are Sheds to stay indoors rather than outdoors space it increased significantly compared to the past. And a wide variety of research about outdoor air quality until recently, efforts are underway but the issue of air quality in the room is the fact that all considered relatively lightly. As the contamination of the room air is polluted, unlike the natural environment, a large outdoor air dilution rate, the dilution rate is very low, once the contaminated air continuously circulating exerts a very bad influence on the health of people staying in the room. In this study, movement characteristics of the person living in a room, the air measuring device for the study of the active indoor environmental control system reflects the life form to measure the quality of the measured air in real time for transmitting the information to the user of the smart devices, alarm bot It was implemented and operational applications.

Recently, The World Health Organization announced that harms human health because of air pollution that are emerging as threats to human health worldwide. according to the, Seoul, 2011 According to a July 2014 - Public Facilities indoor air quality measurements, were examined to be in violation of indoor air pollution standards in most multi-use facility. Indoor air pollution resulting from this is present in the paper, and cause disease, such as pulmonary disease, asthma, bronchitis and to In this connection, the measurement of indoor air quality by using the environment sensor, analyzing the measured data to generate an actuator signal required for ventilation and improve indoor air quality by implementing a monitoring system with real-time measurement, autonomously managing the air quality in our lives so that it can be.

최근 삶의 질이 향상은 건강에 대한 환경적 관심으로 연계되고 있다. 특히 현대인의 생활양식과 근무양식이 1일 실내 생활시간이 전체의 80%이상으로 변화함에 따라 실내공기질(Indoor Air Quality : 이하 IAQ)이 인간에게 직접적인 미치는 영향에 대해 높은 관심을 나타내고 있다. 실내공기는 일정수준의 외기 도입이 없는 경우, 한정된 공간을 오염된 공기가 계속 순환하면서 오염물질이 누적될 수 있다. (중략)

In this paper, we propose the real time indoor air quality monitoring and controlling platform on cloud using IoT sensor data such as PM10, PM2.5, CO2, VOCs, temperature, and humidity which has direct or indirect impact to indoor air quality. The system is connected to air ventilator to manage and optimize the indoor air quality. The proposed system has three main parts; First, IoT data collection service to measure, and collect indoor air quality in real time from IoT sensor network, Second, Big data processing pipeline to process and store the collected data on cloud platform and Finally, Big data analysis and visualization service to give real time insight of indoor air quality on mobile and web application. For the implication of the proposed system, IoT sensor kits are installed on three different public day care center where the indoor pollution can cause serious impact to the health and education of growing kids. Analyzed results are visualized on mobile and web application. The impact of ventilation system to indoor air quality is tested statistically and the result shows the proper optimization of indoor air quality.

서울의 지하철은 하루 450만 명 정도를 수송하는 중요한 대중교통 수단이다. 지하철 역사 내의 실내 환경에 대한 실내공기질 관리는 실내공기 오염의 대상물질에 대한 특정유해물질과 같은 단일 물질에 대한 지표에 의해 관리되고 있다. 그러나 공기중 입자상 물질의 특성은 복합적이기 때문에 공기질에 대한 관리는 여러 제한점을 가지고 있다. 또한 역구내의 먼지에 대한 단순 측정ㆍ분석만이 이뤄지고 있을 뿐 그 먼지의 생물학적 영향에 대한 연구는 미흡한 실정이다 본 연구에서는 지하철역 구내에서 포집한 미세먼지가 돌연변이원을 함유하고 있는 지를 여름과 겨울철에 대한 비교 평가하였다.

최근 실내 공기질(IAQ; indoor air quality)을 악화시키는 물질 중 하나인 이산화탄소 저감 연구가 다수 진행되고 있다. 현재 이산화탄소를 저감하는 방법에는 흡착법, 흡수법, 막분리법 등이 있다. 그 중 흡수법은 액체 상태의 흡수제를 분사하는 공정 특성상 실내에 적용하기 어렵고 2차 오염물 또는 폐수가 발생할 수 있다. 또한, 막분리법은 이산화탄소 분리를 위한 응집 및 침전과 같은 전처리 과정이 필요하므로 실내 이산화탄소 저감에 적합하지 않다. 반면, 흡착법은 비교적 저렴하고 운영이 간단하여 적용 사례가 증가하였으며, 유동 인구가 많고 환기가 어려운 지하철, 버스 등의 대중교통 차량 내부 및 교실, 사무실, 공공시설에서 배출되는 실내 이산화탄소를 제어할 수 있다는 장점이 있어 가장 적합한 해결책으로 알려져 있다. 흡착 공정에 사용되는 대표적인 흡착제 종류에는 활성탄, 제올라이트, 알루미나 등이 있으며, 이 흡착제들을 개질 및 성형하여 흡착제의 성능 및 기계적 강도를 증진시키는 고도화 연구가 활발히 수행되고 있다. 이처럼 적용 대상 내 설치 및 교체가 용이하도록 하는 흡착제 제조 기술 개발이 필요한 실정이며, 흡착제를 상용화 수준까지 발전시킴으로써 강화된 실내 공기질 규제 기준에 대한 대응 및 삶의 질 향상이 기대된다.

As these days people spend most of time at inner space, indoor air quality affect human life seriously. Government manage indoor air quality of various facilities based on different laws. Government released that they would try to protect environment for vulnerable people such children and seniors from indoor air pollutants in 2015. But social welfare facilities are exception under current legal systems. Clients of social welfare residential facilities are the disables, the elderly, homeless and children and they usually stay inner space very long time. The purpose of this study is explore workers' attitude and related factors about indoor air quality management of social welfare facilities. 69.5% of respondents agree to government's indoor air quality management, 80.9% of respondents think social welfare facilities must be included in legal system for indoor air quality management. Environmental awareness and law awareness were related with attitude to indoor air quality management. Based on the results of the analysis, I propose the amendment of law on indoor air quality of the Ministry of Environment, cost burden of central or local government and the necessity of education and research on indoor air quality management in social welfare facilities.
