Abstract. This article examines approximation issues in applied geometry. Calculations in such problems are based on the 3D approximation of curves and surfaces. Surface approximation can be narrowed down to a function of one variable. A type of multifunction interpolation (see article I in the journal) is proposed. Errors are estimated and circular arc interpolation convergence is proven. A brief description of practical application of the method is given.

Notes: This paper, still unknown to English speaking researchers, is, apparently, the first research into the circular arc interpolation for curves.

Eight new mental disorders, donated to the mankind by the Internet and Smartphones

Was translated from by Rushan Ziatdinov

New methods of communication allow people to work more effectively, study better, access new information and entertainment that previously were not available to them. However, this phenomenon has another side. Internet and mobile devices, from which their owners are virtually inseparable, gave rise to new psychological disorders that medical scientists have been unwilling to acknowledge until recently. - a website focusing on the technologies provides an overview of the most common problems that it makes no sense to deny.

Phantom ringing syndrome. This condition can be described as experiencing auditory or motor hallucinations and false belief that there is a phone ringing or vibrating inside one’s pocket. It is caused by the use of a mobile phone. A person begins to associate any stinging or slight itching with a phone call. This disorder is brought about by the stress. It is fairly common.

Nomophobia. The term is an abbreviation for “no-mobile-phobia.” In other words, it is the fear of being left without a mobile phone. The number of people around the world, who do not suffer from this disorder, is getting smaller. A person can experience mild anxiety or go into a mad panic, when he or she cannot use a mobile phone, e.g., because of a dead battery.

Cybersickness. It is the feeling of dizziness, disorientation and nausea, caused by the interaction with certain electronic devices. The term was coined back in the 1990s, when the first virtual reality devices emerged. Some iPhone owners report feeling nausea after upgrading to a new version of the iOS. Another name for this condition is "digital motion sickness."

Social networks depression. The gist of it is that people get depressed when contacting in a social network or, alternatively, by the absence of the same. It is proved that more time young people spent on social networks, the worse was their mood and attitude towards life. The point here is that people tend to post only those photos and personal information that put them on a spin. This creates an impression that friends and acquaintances have a better, brighter and more intensive life than you have, their photos are more successful, figure is better, and watches are more expensive.

Internet addiction. It is a painful and constant desire to gain access to the Network, which has a negative impact on other areas of life, often forcing them out completely. For example, personal life or work. In academic circles the debates keep going, whether it is possible to consider the Internet addiction as a drug addiction or mental disorder.

Online games addiction. This is a well-known and devastating disease. There are cases known, when the game literally dragged out a man into the virtual world, and as a result, he was losing his job, family, and even life. This disorder causes severe depressions and can lead to physical exhaustion and even suicide.

Cyber English Disease. A person with this disorder believes that he has a disease and, as a rule, not a single one, of which he had read on the Internet. As a result, a healthy man, who just has a headache, may convince himself that he has got a serious problem. And such a conviction may adversely affect the health and lead to a real and not imaginary disease.“The Google effect”. A person with such disease believes that he needs no knowledge since all information is just within a few clicks. However, even if someone thinks otherwise, it does not give him immunity from the “Google effect”. The brain simply refuses to remember the information regardless of our will, knowing that it is much easier to find the data than to store it.
