Każdego roku na polskich budowach dochodzi do kilku tysięcy wypadków przy pracy. Niniejszy artykuł przedstawia metodykę prognozowania skutków wypadków z udziałem rusztowań budowlanych na podstawie autorskiej metodyki przesiewania. Podstawą dla przeprowadzonych badań był zbiór danych pozyskanych z zasobów Państwowej Inspekcji Pracy dotyczący 200 wypadków. Wyniki badań pozwalają na procentowe określenie prawdopodobieństwa wystąpienia lekkich, ciężkich i śmiertelnych skutków wypadku.

Each year, several thousand accidents at work occur on Polish construction sites. This article presents a methodology for predicting the consequences of accidents involving construction scaffolding on the basis of the author's screening methodology. The basis for the research was a set of data obtained from the resources of the National Labour Inspectorate concerning 200 accidents. The results of the study allow for a percentage determination of the probability of light, heavy and fatal consequences of an accident.

Purpose: Falls are one of the main causes of injuries in older adults. This study evaluated a low-cost footswitch device that was designed to measure gait variability and investigates whether there are any relationships between variability metrics and clinical balance tests for individuals with a history of previous falls. Methods: Sixteen older adults completed a history of falls questionnaire, three functional tests related to fall risk, and walked on a treadmill with the footswitch device. We extracted the stride times from the device and applied two nonlinear variability analyses: coefficient of variation and detrended fluctuation analysis. Results: The temporal variables and variability metrics from the footswitch device correlated with gold-standard measurements based on ground reaction force data. One variability metric (detrended fluctuation analysis) showed a significant relationship with the presence of past falls with a sensitivity of 43%. Conclusion: This feasibility study demonstrates the basis for using low-cost footswitch devices to predict fall risk.

Foot slippage is the most widespread unforeseen event causing falls on the same level, and a potentially contributing factor to falls from height and falls to a lower level. Statistical data on the number of slip-related accidents at work show the importance of the problem of slipping and indicate the need to continuously improve preventive measures designed to reduce injuries related to slipping, tripping, and falling (STF) on the same level. It is therefore necessary to continuously and insightfully analyze the causes of falls and undertake efforts to eliminate the occurrence of slip- and trip-induced workplace accidents. The occurrence of slips and trips is primarily related to the type and quality of floor surfaces, but it also depends on the biomechanical characteristics of the lower limbs in the transitional phases of walking gait, sole material and tread, human factors such as age, weight, and motor and vision function, the ability to adapt to the floor surface conditions, as well as on a number of factors linked to the workplace environment and work organization. This problem is going to escalate as a result of the higher retirement age, due to which many persons over the age of 60 will have to continue working, often in hazardous conditions.

Since the first recorded discovery of a meteorite in 1937 near the Mrirt village (Khenifra, Morocco), a total of 946 authenticated meteorites have been recorded in Morocco. The material, including 10 observed falls, comprises 918 stones, 13 irons and 15 stony-irons. A low ratio of falls to finds (represent only 0.01 % of the Moroccan declared meteorites) compared with other countries (e.g., USA 14.3 %). However the rate of recovery of meteorites (falls + finds) in Morocco exceeds that of most other countries of similar size and range of climatic conditions. More than 95 % of documented meteorites from Morocco have been recovered from Eastern Morocco (Eastern Sahara Moroccan) including many rare types. This Region has proved to be one of the most prolific areas in the world for meteorite finds.

The goal of this study was to quantify the effect of experience and handrail presence on trunk muscle activities, rotational spinal stiffness and postural stability of construction workers. We evaluated spinal stability, and objective and subjective postural stability in 4 expert and 4 novice construction workers who were performing a manual task in a standing position on a scaffold, with and without a safety handrail. Center of pressure was computed using measurements taken with insole pressure transducers. Muscle activity was monitored usingsurface electrodes placed on 8 trunk muscles that predicted active trunk rotational stiffness. Standard deviations of the center of pressure, back muscle activity and spinal stiffness were greater in novices and in the absence of a handrail. We infer that the risk of a fall due to postural and spinal instability may be greater with a lower level of experience and in the absence of a safety handrail.

During the last eighty years, thirteen meteorite falls were recorded in Morocco, which ten are well documented and named Douar Mghila, Oued el Hadjar, Itqiy, Zag, Bensour, Oum Dreyga, Benguerir, Tamdakht, Tissint and Aoussred. It represent only 0.011 % of the Moroccan declared meteorites.The authenticated observed falls represent three types of different meteorites, eight ordinary chondrites (Four of type LL, three of type H and one of type EH), one carbonaceous chondrite and one Shergottite basaltic achondrites. The Morocco meteorite fall recovery rate, during the past eighty years, is low 0.11 falls per year on average per 2.11 km2 (or approximately one fall recovery per 10 year time interval).
