“…Therefore, it is recommended that either the passive detectors to be installed for a longer period of time, i.e. 6–12 months 28 – 31 , or to reduce the uncertainties associated with the temporal correction factor assessment by other means 32 – 36 . The increase of measurement period, however, is not often an option in the present age of speed, especially in countries where real estate transactions are conditioned by the existence of a radon measurement 37 , 38 .…”

The present study aims to identify novel means of increasing the accuracy of the estimated annual indoor radon concentration based on the application of temporal correction factors to short-term radon measurements. The necessity of accurate and more reliable temporal correction factors is in high demand, in the present age of speed. In this sense, radon measurements were continuously carried out, using a newly developed smart device accompanied by CR-39 detectors, for one full year, in 71 residential buildings located in 5 Romanian cities. The coefficient of variation for the temporal correction factors calculated for combinations between the start month and the duration of the measurement presented a low value (less than 10%) for measurements longer than 7 months, while a variability close to 20% can be reached by measurements of up to 4 months. Results obtained by generalized estimating equations indicate that average temporal correction factors are positively associated with CO2 ratio, as well as the interaction between this parameter and the month in which the measurement took place. The impact of the indoor-outdoor temperature differences was statistically insignificant. The obtained results could represent a reference point in the elaboration of new strategies for calculating the temporal correction factors and, consequently, the reduction of the uncertainties related to the estimation of the annual indoor radon concentration.

“…Additionally, they utilized t-tests, Mann-Whitney tests ( M − W tests) for two samples, or Kruskal-Wallis tests (K–W tests) with Dunn's post-hoc analysis for more than two samples to compare the datasets. By calculating Pearson or Spearman correlation coefficients, the authors were able to assess the strength of the relationship between the variables being studied [ 62 ].…”

“…The results of research, partial research or studies that have been devoted to indoor air quality show that the authors examined this issue most often through questionnaire surveys among employees working mostly in office buildings (Zainon et al, 2016;Roskams and Haynes, 2019) and open space offices (Maula et al, 2017), laboratory conditions and call centers (Wyon, 2004) or in residential buildings as air pollutantsradon, volatile organic compounds (VOCs) and carbonyl compounds (Beldean-Galea et al, 2020). Research with a similar focus has also been conducted in administrative spaces and has focused on the quality of the internal environment in the harbor storage building (Niemel€ a et al, 2002).…”

PurposeThe aim of this paper is to examine how indoor aromatization affects the expressed and unexpressed satisfaction with the work environment in the production hall of an industrial company.Design/methodology/approachThe aroma was flavored by an aromatization unit, the expressed satisfaction was measured on a scale and biometrics of facial recognition (FaceReader) was used to measure unexpressed satisfaction, enabling the recording of eight emotions and two basic emotions.FindingsResearch has shown the effect of aroma on two emotions – neutral and angry – which partially confirmed the sense of flavoring production facilities. Previous research has shown that positive feelings caused by a pleasant smell influence customers' purchasing decisions. As the use of aroma affects the mental state of the individual, it could be also applied for non-marketing purposes.Originality/valueTo date, there has been no research that systematically addresses the impact of aromatization on the perception of the work environment in a manufacturing company. The presented study is unique in its design and focus and provides basic information about the impact of aroma on individuals. The findings of this study can help to examine further aspects that indirectly affect performance.
