Recently, the issue of air quality in South Korea reached an unprecedented level of social concern regarding public health, quality of life, and environmental policies, even as the level of particulate matter less than 10 μ m (PM 10 ) showed a decreasing trend. Why have social concerns emerged in recent years, specifically after 2013–2014? This study aims to understand how people perceive air quality apart from the measured levels of airborne pollutants using internet search volume data from Google and NAVER. An empirical model that simulates the air quality perception index (AQPI) is developed by employing the decay theory of forgetting and is trained by PM 10 , visibility, and internet search volume data. The results show that the memory decay exponent and the accumulation of past memory traces, which represent the weighted sum of past perceived air quality, play key roles in explaining the public’s perception of air quality. A severe haze event with an...

公众对空气质量的认知和认识中有哪些重要问题？使用互联网搜索量数据进行定量评估

近来，即使小于10微米（PM 10）的颗粒物含量呈下降趋势，韩国的空气质量问题也达到了前所未有的社会关注程度，涉及公共卫生，生活质量和环境政策。为什么近年来出现了社会问题，尤其是在2013-2014年之后？这项研究旨在利用Google和NAVER的互联网搜索量数据，了解人们对空气质量的认识，以及所测量的空气中污染物的水平。通过采用遗忘的衰减理论，开发了一种模拟空气质量感知指数（AQPI）的经验模型，并通过PM 10，能见度和互联网搜索量数据进行了训练。结果表明，记忆衰减指数和过去记忆轨迹的积累，代表过去感知到的空气质量的加权总和，在解释公众对空气质量的感知方面起着关键作用。一场严重的霾事件，有...
