The levels of noise arise from mining industry seem to be higher when compared to other industries. For this reason, noise exposure and noise-induced hearing loss (NIHL) are prevalent in mining. Assessment of noise emission levels that arise from various mining operations is required to prevent and minimize the NIHL. Because the studies for preventing occupational hearing loss among miners are inadequate, a quarry and stone crushing-screening plant was selected to generate site-specific data. The noise levels of the environments in which workers work were measured and also a hearing test centre applied hearing tests to the workers. According to the hearing test results, it was determined that the part of workers have hearing loss. The main factors affecting the NIHL were assumed as experience, noise level, miners' age and occupation, and by taking into account the sub factors of the main factors, multi way contingency tables were prepared. Then hierarchical loglinear analysis method was implemented to categorized data; thus, the probabilities might effect NIHL was investigated. At the end of this study, it was found that the most risky occupation group was the drivers, and additionally, these workers were mostly exposed to 70-79 dB(A) noise level. When the important interactions are evaluated, it is determined that 4-11 years experienced crusher workers have high probability of NIHL because of high exposure to 90-99 dB(A) noise level. Moreover, the most important interactions which may affect the NIHL were identified and the precautions to reduce hearing loss were presented.
Clays are used in the general production of earthen tiles. In this study, the production and characterization of earthen tiles from schist, a clayey rock formed by metamorphism of mudstone or shale, was investigated. The impact of tiles on atmospheric temperature through their absorption of the visible, near-infrared and far-infrared wavelength regions is evaluated. In particular, the absorption of ultraviolet and infrared radiation by the tiles was evaluated, as this could have beneficial applications for human health and the environment. UV-A radiation (320–400 nm) is not absorbed by the atmosphere, but schist materials absorb UV-A, which can contribute to melanoma formation (i.e. cancer). Field-emission scanning electron microscopy, X-ray fluorescence spectrometry and X-ray diffraction were used for the analysis of the schist materials. The tile-production stages of schist materials (drying, firing, water absorption rate, etc.) were tested at Hatipoglu Gunes Tile and Brick Industry, Inc. (Turkey). The tiles fired at 950°C and 1000°C comply with the industry standard compressive strength values for fired tiles (when converted to industry production conditions) and were 156.15 and 123.20 kg cm–2, respectively.
Background The increase in the use of information and communication technologies around the world brings about developments and changes in the provision of health services. It is accepted that telemedicine applications will facilitate health services for patients and health personnel. This study aimed to evaluate the telemedicine awareness, knowledge, attitude and skill levels of physicians and medical school students. Methods This cross-sectional study was conducted between July and August 2021. A questionnaire form was prepared using the relevant literature then filled online by the participants. Telemedicine Awareness, Knowledge, Attitudes and Skills Questionnaire was used in the research. The universe of the research consisted of medical faculty students and physicians across Turkey. In the study, 933 people were reached by using the purposeful snowball sampling method, one of the non-probability sampling methods. Mann Whitney-U test, Kruskal Wallis test, Spearman correlation analysis and Multiple Linear Regression analysis were used. Results Of the participants, 442 (47.4%) were female, 497 (53.3%) were medical students, and 436 (46.7%) were physicians. Their ages ranged from 18 to 59, with a mean of 28.0±8.8 years. The median (min-max) scores obtained from the Telemedicine Awareness (TA) sub-section were 18(0-24), 51.3% of them had scores above the median score. TA sub-section had a moderate positive correlation (r = 0.559, p < 0.001) with knowledge sub-section and a weak positive correlation (r = 0.208, p < 0.001) with skill level sub-section. TA scores were higher among men, physicians and those who want to participate in a telemedicine training program. TA increased as the level of computer and internet knowledge increased (F = 29.171, R2=0.197, p < 0.001). Conclusions It can be said that TA is at a moderate level among medical students and physicians in Turkey. TA increased as the level of computer and internet knowledge, telemedicine knowledge and skills increased. Key messages
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
