The rapid development of information technology, cybernetics, and mass media communications was greatly influenced by the unification of countries to improve and use the results obtained to improve the quality of life and progress in all spheres of human activity. Today it is impossible to imagine life without the Internet, digital television, mobile communications and technologies associated with them. World Telecommunication and Information Society Day is traditionally celebrated by all communications and information technology specialists on May 17. By signing the first International Telegraph Convention in Paris back in 1856, representatives of twenty countries, including Russia, gave an unimaginable impetus to the development of telecommunications, initially in the revolutionary development of that time - the telegraph. By creating the International Telegraph Union, countries were able to achieve uniform standards regarding equipment and parameters of signals transmitting information. Agreements were also reached on other aspects - organizational and legal. But scientific progress did not stand still, and with the advent of radio and telephone, and a little later television, the name of the union ceased to correspond to all available types of communication. Therefore, in 1932, at the next conference, a new International Telecommunication Convention was introduced. In 1934, the union received a new name - the International Telecommunication Union (ITU). And 13 years later, ITU became a specialized agency of the UN. The holiday itself - World Telecommunication Day - received its name and official status in 1969, and in 2006 it again changed its name, which it still has to this day. It is worth noting that the theme of the holiday changes every year, this is due to the fact that in the constantly changing information world, new issues arise related to the introduction and use of the latest technologies, ensuring access and distribution of all types of communications everywhere, increasing security and performance, and many others. In the last years of the new millennium, at conferences and other events designed to ensure the availability of information about innovative discoveries and their application in the field of communications and mass media, an analysis of the work performed was carried out and questions were raised about overcoming the following problems: - cybersecurity; - the use of infocommunication technologies (ICT) people with disabilities; - use of ICT by youth; - increasing the availability of ICT in remote and isolated rural settlements; - gender equality in the use of ICT; - environmental aspects of the use of ICT and others. In a dynamically changing world, ITU has an important mission - bridging the digital divide and ensuring equal opportunities to use ICT in all corners of the planet for a harmonious and creative future for humanity.

The World Wide Web was created as a system that provides access to interconnected documents located on various personal computers that are connected to the Internet. Initially, the Network allowed users to digitally send letters, download files, and read newsletters. On May 17, 1991, a single standard for website web pages was approved. After the invention of the World Wide Web, this became another leap in the development of information technology. That's why the Internet's birthday is celebrated annually on May 17th. The celebration of this event is taken seriously by both programmers, web designers and other IT specialists, as well as ordinary people. For computer scientists, the Internet is the sphere of application of their professional skills and abilities, and for users it is the opportunity to receive and exchange information, access music and video content, organize sales of goods and offer services in the virtual world. It is difficult to imagine modern life without access to the global information space. Every second resident of Russia logs into the Internet at least once a day. Therefore, citizens of the Russian Federation, like other countries of the world, celebrate the Internet’s birthday not just once, but several times a year. The communication session conducted on October 29, 1969 between the first Network nodes located at Stanford and the University of California was completed successfully. The researchers sent and received the first two characters from the abbreviation LOG (part of the word LOGIN - commands to log into the system). After this, the Network stopped functioning, but it was repaired and the next attempt, which the scientists made on the same day at 22:30, was successful. Therefore, October 29 is considered one of the solemn dates associated with the invention of the Internet. Residents of Catholic countries attach so much importance to the emergence of the World Wide Web that they even found a saint who patronizes the Network. This was the Spanish Bishop Isidore of Seville, who lived in the 6th-7th centuries and was known as a great encyclopedist and writer. The choice of the saint's birthday, April 4, to celebrate the advent of the Internet is justified. The system provides access to a gigantic database and reference information of a truly encyclopedic nature. And yet, the Internet in its current form, to which we are accustomed, appeared on May 17, 1991, when the standard for WWW (World Wide Web) pages was approved. With the advent of special programs, i.e. browsers opening these pages, the Network began to develop rapidly and be filled with new content every second. In June 2011, the UN adopted a resolution that made Internet access a basic human right. In modern realities, it is truly impossible to imagine the life of most people without the ability to use the Internet. Paying tribute without exaggeration to the greatest invention of mankind, on May 17 the Internet is celebrated around the world.

Physical inactivity, poor diet, severe nervous tension, smoking, excess weight, alcohol abuse and high cholesterol levels contribute to increased blood pressure. Over time, this leads to hypertension, which is diagnosed in 1.8 billion people, i.e. Every third person on the planet suffers from it.

Diseases of the respiratory system are diagnosed in both adults and children. Over time, a large amount of knowledge has accumulated in this area, which led to the creation of a new direction in medicine. Doctors who specialize in the prevention and treatment of respiratory diseases are called pulmonologists.

Baha'i Holidays - Feast of the Nineteenth Day of the Month of Azamat

On May 17 (May 4, old style), according to the folk calendar, Pelageya the Intercessor or Baklushnik Day is celebrated. The date was named in honor of the holy martyr Pelagia of Tarsus, whose memory is celebrated by Orthodox Christians on this day. Pelagia was born in the 3rd century in Tarsus (modern Tarsus, Turkey) into a wealthy pagan family, and was a beautiful and educated girl. After accepting Christianity, they tried to forcibly betroth her to the adopted heir of Emperor Diocletian. Pelagia refused, declaring her devotion to Christ. Her failed husband, knowing how Christians were tortured, committed suicide out of grief for his bride. Seeing the beautiful Pelagia, the emperor himself wanted to marry her, but the girl was against it, for which she was painfully executed. People called Pelagia (Pelageya) the protector of birds, so they tried not to offend birds on this day. The saint also patronized girls and women whose names had been undeservedly slandered. If the girls were innocent of what they had done, then they prayed to Pelageya for protection from their offenders. Those who were truly guilty did not dare to pray to the saint. Another name for the date, Baklushnik Day, was derived from the tradition of going into the forest to pick trees to make baklushniks. Wooden kitchen utensils were called baklushi: spoons, bowls, spatulas. More often they were carved from linden, birch or aspen. The making of baklush was carried out by craftsmen who were freed from field work. They tried to decorate spoons with paintings and carvings, since such utensils symbolized the status of wealthy peasants. Before sunset, residents performed a ritual to protect the seedlings from evil spirits. To do this, a cracked pot was placed in the center of the garden, and a nettle bush, pulled out with its roots, was placed inside. Then a special conspiracy was read out. They believed that stinging nettle would drive away from the earth all evil spirits and insects that had become attached to the young shoots of seedlings and rising grains. If a lot of cockchafers were observed on Pelageya Intercessor, we were preparing for days without precipitation. The cuckoo's cuckooing on Pelageya was heard during warm weather. Sparrows fluttering across the sky foreshadowed windy weather. A rainy day promised a bountiful harvest. The sloe blossom meant the second half of May would be cool.
