Fundamentals of Safe Life Activities (OBZhD)

The nature and organization of labor detail have a significant impact on the change in the functional state of the human body. Various forms of work activity are divided into physical and mental labor.

Physical work requires great muscular activity and takes place in the absence of mechanized means for work (the work of a steelworker, loader, vegetable grower, etc.). It develops the muscular system, stimulates metabolic processes in the body, but at the same time it is not socially effective, has low productivity, the need for a long rest:

1) a mechanized form of labor requires special knowledge and motor skills, small muscles of the arms and legs are included in the work, which ensure the speed and accuracy of movement, but the monotony of simple actions, a small amount of perceived information leads to monotony of labor;

2) work associated with automatic and semi-automatic production has the following disadvantages: monotony, increased pace and rhythm of work, lack of creativity, since the mechanism is engaged in the processing of objects, and the person performs simple machine maintenance operations;

3) conveyor work is distinguished by the fragmentation of the process into operations, a given pace and rhythm, and a strict sequence of operations.

The disadvantage is monotony, leading to premature fatigue and rapid nervous exhaustion; labor associated with the management of production processes and mechanisms, when a person acts as an operator, and the less automated the management process, the greater his participation.

Brainwork associated with the perception and processing of a large amount of information and is divided into:

1) operator - control over the operation of machines. Differs in high responsibility and neuro-emotional stress;

2) managerial is characterized by a large increase in the volume of information with a lack of time for its processing, great personal responsibility for decisions made, stressful and conflict situations;

3) creative work requires a large amount of memory, tension, attention. Leads to an increase in neuro-emotional stress, tachycardia, increased blood pressure, ECG changes and other shifts in autonomic functions;

4) the work of teachers and medical workers - constant contact with people, increased responsibility, frequent lack of time and information to make the right decision, which leads to high neuro-emotional stress;

5) work of pupils and students. It requires concentration of memory and attention. There are stressful situations (exams, tests).

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Harm of gas stoves 29.01.2022

Leaking methane from stoves in US homes has the same climate impact as about 500 gasoline-powered cars, researchers estimate, and stoves can expose people to pollutants that cause respiratory illness.

Natural gas stoves emit methane, a potent greenhouse gas, as well as other pollutants through leaks and incomplete combustion.

Stanford University researchers have calculated that methane leaks from stoves in American homes have the same impact on the climate as about 500 gasoline-powered cars, and stoves can expose people to pollutants that cause respiratory illness.
