MATERIALS AND METHODS In 69 patients, the dose reduction protocol was divided into A, B, and C test groups- 60% (n = 22), 50% (n = 23), and 40% (n = 24) of the baseline dose. In each patient, baseline dose radiographs were obtained with conventional image processing while low-dose images were acquired with new image processing. A set of baseline and low-dose radiographic images per patient was evaluated and scored on a 5-point scale over seven anatomical landmarks (radiolucency of unobscured lung, pulmonary vascularity, trachea, edge of rib, heart border, intervertebral disc space, and pulmonary vessels in the retrocardiac area) and three representative abnormal findings (nodule, consolidation, and interstitial marking) by two thoracic radiologists. A comparison of paired baseline and low-dose images was statistically analyzf patient's and radiography technologist's radiation safety in routine clinical practice, in compliance with regulatory guidelines.Irony is one of the linguistic means in which intended and expressed meaning diverge. It serves social-communicative functions, requires the understanding of the speaker's mental state and its comprehension takes place at an advanced stage of language acquisition. In the present study, we investigated 8-year old's irony comprehension and social skills and asked their parents about their preferred use of irony towards their children. We then compared children with the highest scores in irony comprehension test with those with lower scores. The full sample included 46 families from Poland. Results show positive associations between children's levels of irony comprehension and levels of mothers irony use. No such relations were found for fathers. No differences were found in T
