TL;DR: In this article, the dry-bulb temperature, relative humidity, the airflow velocity, and the globe temperature were measured at 10 randomly selected kindergartens from April to June, 2013, and a survey was conducted three times a day for 119 kindergarten children to investigate their thermal comfort, clothing insulation, and metabolism.
76 citations
TL;DR: In this article, the average indoor concentrations of fine particles less than 2.5μm were collected from inside ten childcare centers, and from their adjacent outdoor environments in Seoul, Korea during the summer, autumn and winter seasons.
75 citations
TL;DR: In this article, the indoor air quality measured at elementary schools in Seoul, Korea showed generally low levels of pollutants due to low occupancy and adequate ventilation and the indoor levels of PM10 and TBC in schools near roadways were significantly lower than other surrounding environments due to dispersion of pollutants, without obstruction by buildings and mountains.

TL;DR: In this paper, the authors investigated the distribution of Asbestos containing materials (ACMs) in Korea for 15 school buildings built before and after 1990, including elementary schools, middle schools and high schools.
Abstract: We investigated the distribution of Asbestos containing materials(ACMs) in Korea for 15 school buildings built before and after 1990, including elementary schools, middle schools and high schools. In order to perform risk assessments of samples gathered from the buildings, the study used four different rules as the criteria: results from the AHERA rule, the HSE rule and the ASTM rule on ACMs were measured against the available risk assessment of asbestos in Korea, a rule was proposed based on schools environment and background. In the ACMs aging of the samples before 1990, chrysotile and amosite in the ceiling samples were detected 2-5 % and 2-3 %, respectively. Overall, a higher detection rates was found in samples emanating in baumlight (chrysotile 5-8 %) used in a cubicle partition in the bathroom more than ceiling samples (chrysotile 2-5 %) taken from classrooms. As a result of air samples of asbestos, most of the samples had concentration levels below of Indoor Air Quality Management Standards (0.01 fiber/cc), except for two samples in the kindergarten and elementary school. Risk assessment and evaluation of ACMs indicated the similar results in AHERA rule, HSG264 rule and ASTM rule and proposed the new assessment(available risk assessment of asbestos in Korea) was made based on the Korea background.

TL;DR: In this article, a review of the impact of PM2.5 in indoor urban environments summarizes existing research in this area, specifically, the main sources and sinks in outdoor and indoor environments, the exposure limits that are currently applicable throughout the world, and the main socioeconomic impacts of exposure to PM 2.5.

TL;DR: In this article, a field study about indoor thermal comfort, based on investigations in Portuguese secondary schools' classrooms, was conducted by physical parameters monitoring and survey questionnaires, and the results show that the students found temperature range beyond the comfort zone acceptable, and revealed occupants' accommodation to CO2 exposure, confirming the results obtained in other studies.

TL;DR: In this paper, the relationship between temperature and subjective thermal sensation is non-linear and depends on the type of scale used, and most people do not perceive the relationship at all.
Abstract: Scales are widely used to assess the personal experience of thermal conditions in built environments. Most commonly, thermal sensation is assessed, mainly to determine whether a particular thermal condition is comfortable for individuals. A seven-point thermal sensation scale has been used extensively, which is suitable for describing a one-dimensional relationship between physical parameters of indoor environments and subjective thermal sensation. However, human thermal comfort is not merely a physiological but also a psychological phenomenon. Thus, it should be investigated how scales for its assessment could benefit from a multidimensional conceptualization. The common assumptions related to the usage of thermal sensation scales are challenged, empirically supported by two analyses. These analyses show that the relationship between temperature and subjective thermal sensation is non-linear and depends on the type of scale used. Moreover, the results signify that most people do not perceive the ...
