2. CLASSIFICATION OF THE MAIN FORMS OF ACTIVITY

The main forms of labor 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 socially inefficient, has low productivity, and requires a long rest.

The 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 lead to the monotony of labor.

Labor associated with automatic and semi-automatic production has the following limitations: monotony, increased pace and rhythm of work, lack of creativity, since the processing of objects is handled by the mechanism, and the person performs simple operations to service the machines.

Conveyor work is distinguished by the fragmentation of the process into operations, a given pace and rhythm, and a strict sequence of operations. Its disadvantage is monotony, leading to premature fatigue and rapid nervous exhaustion.

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

1) cameraman - involves the control of the operation of machines; is distinguished by high responsibility and neuro-emotional stress;

2) managerial - 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, stress, attention; it leads to an increase in neuro-emotional stress, tachycardia, an increase in blood pressure, an ECG change and other shifts in autonomic functions;

4) work of teachers and medical workers - this is 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 - implies concentration of memory, attention; there are stressful situations (at exams, tests).

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Mini air conditioner Sony Reon Pocket 5 09.05.2024

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Super sharp wooden knife 03.11.2021

Scientists from the University of Maryland (USA) have come up with a new way to make sharp wood-based knives. Unlike the production of knives from artificial materials such as steel and ceramics, this method is more environmentally friendly.

The Miracle Knife cuts through medium-rare steak with ease, and has the same performance as a regular kitchen knife.

The new method makes the wood 23 times harder, and the finished product is almost three times sharper than a conventional stainless steel knife.

A hardened wood knife can be washed and reused, making it a promising alternative to steel, ceramic and disposable plastic knives. Also, hardened wood can be used to produce wooden nails that are not afraid of rust, and a parquet board that is resistant to scratches and wear.
