The aim of the present study was to compare the mental capacity changes in school teachers, depending on age and type of school. 120 teachers drawn from the secondary and technical schools of Sofia were divided into two groups of younger (mean 31.5 yrs) and older (mean 47.5 yrs) age. They were given two monotonous visual tasks, which differed in complexity: of discrimination and of categorization. The behavioral measures of performance revealed lower efficiency in categorization due mostly to the so-called "premature" or "impulsive" reactions. Significant positive correlations were found between age and within-individual variability of reaction time, suggesting an earlier onset of the aging processes in the investigated population. The decrease in performance efficiency which was age-related was most expressed in the secondary school teachers. It was concluded that the changes of mental capacity can be regarded as an indirect indicator of the occupational stress of the school teachers.

The ruins of the Imperial City of the Minyue Kingdom were an important site of the Minyue Kingdom during the Han Dynasty. Characteristic bronze arrowheads unearthed from the East Gate, with their exquisite craftsmanship, provide important physical evidence for studying ancient bronze casting technology and the military activities of that time. However, there is still a lack of systematic research on the alloy composition, casting process, and chemical stability of these arrowheads in long-term burial environments.

Physical Education and Exercise Research Center, Pegaso Telematic University, 80143 Napoli, Italy.
Background And Objectives: The preschool context produces excessive sedentary behavior in children. The systematic fulfillment of structured physical activities during school time, namely a daily movement routine (DMR), can contribute to increasing the quantity of physical activity (PA) and to improving physical literacy (PL), reaching the WHO's recommendations.
Aim: The present study aims to quantify the sedentary time spent by 4- and 5-year-old preschool children and to verify the effects that a DMR could have on sedentary habits in preschool children.
