The study of isolation in the collectives of special-purpose railroad cars as an element of the sustainable development of social systems

. The article provides examples of labour social isolations. Multiple professions in which social isolation is present are compared, and differences are revealed both in the process of isolation itself and the influence of other psychogenic factors. The question was raised about the complexity of classifying labour social isolation. The definition of social exclusion is given. Teams that face social isolation were considered. The main differences were identified, both in psychogenic factors and in the isolation itself, of each profession. The fact of the existing social isolation in the collectives of specialized railroad cars was proved by conducting empirical studies in these collectives. The "Results" section presents a table that reflects the main psychogenic factors in the professions considered. Based on the data, a classification of labour social isolation was made. The classification of isolation types was represented by two groups: deprivation social isolation, rather acute isolation; irritable social isolation, less problematic but more common social isolation. The possibility of creating a universal "isolation passport" is discussed. All factors of social isolation of the group can be combined into three components: external factors; organizational and production factors; socio-psychological factors.


Introduction
In 2020, almost every person living on Earth had undergone social isolation. Social isolation, as a forced quarantine measure caused by the coronavirus (COVID-19), has dramatically changed the way of life of billions of people. Millions of people have lost their jobs, causing economic problems in a series of countries. The leaving of the house was strictly regulated by the rules in many countries. Many people have experienced depression, problems in relationships with their families, conflicts, irritability, and increased alcohol consumption. All these psychological problems arise not only from the worsening economic situation of the economic situation, but also from the quarantine measures taken, i.e., from social isolation. The damage from forced quarantine measures has been bearly studied. The study of this problem interested: economists, psychologists, and sociologists. A new scientific field has emerged for numerous studies of social exclusion. psychological state of a person caused by the consequences of certain social isolation: one person can develop hard depression on the tenth day of being on a fishing boat at sea. Another person may have mild irritability on the sixty-tieth day of being on the ISS.
The second way is to start with social isolation. The social group itself is of great importance, namely: the number of members in the group; the opportunity to form psychological communication in an informal subgroup; the presence of trust and cohesion in the group; group readiness. This issue of the formation of the sociopsychological characteristics of a group and subgroup is described in the paper by A. Sidorin in the monograph: "Methods for the sociopsychological study of small groups in an organization", Southern University Publishing House in 2012. In some isolated groups, especially with a small number of people, this has measurable weight. After all, 30-day isolation with 6 or 7 group members is not the same as 30-day isolation with 3 group members.
It was mentioned above that psychogenic factors arise, caused directly by the social group's habitat specifics. Consequently, it is hard to classify labour social isolation based on the consequences of the impact on the human psyche because the person oneself, the number of people in the group, the quality of communication, etc., are variables. Therefore, the classification must be carried out based on the characteristics of professions that affect the human psyche in different ways.
The purposes of this article are: ─ classification of labour social isolations arising in certain labour collectives; ─ proof of the fact of labour social isolation in the collectives of specialized railroad cars; ─ inclusion of isolation in the collectives of special-purposerailroad cars in the created classification of labour social isolations; ─ to identify the general patterns of the course of psychogenic factors of social isolation.

Methods
As part of the study of labour social isolation, it is necessary to define the social exclusion of a small group.
The social isolation of a small group is the isolation of a collective (small social group) in places of temporary or permanent residence isolated from the rest of society, whose members are forced to communicate mostly with each other. At present, there are many such groups. The following categories of people are subjected to isolation to varying degrees: astronauts, specialists of professions working on a rotational basis (polar explorers, sailors, oil workers), and prisoners. In an isolated group, a person in the process of work and rest is forced to communicate with the same people, while his rest is sharply limited.
To classify labour social isolation, it is necessary to consider the isolated labour collectives themselves to describe the specifics of their work and life. These are the crews of the space station and interplanetary flight, submarine and sea vessel, polar explorerswinterers, teams of shift workers, and crews of special-purpose railroad cars. Let us describe the characteristics of social isolation itself, the characteristic of each area, and indicate additional psychogenic environmental factors. According to Lebedev V.I. in the monograph "Personality in extreme conditions" by the publishing house "Politizdat" in 1989, the highlighted psychogenic factors in extreme conditions, as a rule, affect a person, not in isolation but in combination, therefore they must be considered comprehensively.
Labour social isolation of the staff of the space station and space flight. This social isolation is the most harmful in terms of influence both on the human psyche and its physiology. Astronauts are constantly in a zero-gravity field, which completely changes life. Astronauts are deprived of much and are in constant danger. Astronauts, during their stay at the station, develop various distortions of perception and psychological disorders caused by sensory deprivation, as described by V. Lebedev.
In isolation, the great difficulties in communicating with people outside the circle of isolation. Communication with other people outside the circle of isolation is strictly regulated. Colleagues, family members, friends, and relatives who remained on Earth undergo strict instructions to provide psychological support without observing the rules of which communication with the astronaut is prohibited.
The psychological preparation of the space crew members begins long before the start of the flight. Individual employees of the flight control centre (controllers) also take part in such training to obtain effective socio-psychological characteristics of the group. As a rule, many flight control centre controllers are astronauts themselves, i.e., have already been in space, which allows one to achieve cohesion, trust, and better understand one's colleague.
The social isolation of deep space flight is very different from the isolation of an astronaut on a space station. The main difference is the lack of communication in deep space. These "deep space" flights have not yet been carried out, but the problem is already actively discussed by N. Kanas et al. [4]. 'Support provided to ISS crews includes private family conferences via real-time audio or Internet channels, which will not be possible during a flight to Mars due to communication delays due to large distances.' The problem of "deep space" is actively discussed by E. Salas et al. [5]. E. Salas suggests using specialized equipment. This equipment is a set of individual physiological sensors. The data from the sensors allow each cosmonaut to receive data on the psychoemotional state of a colleague at a given time.
It is somewhat difficult to classify the social isolation of the space station staff and the isolation of deep space flight. These isolations have a lot in common (zero-gravity, duration), but communication problems greatly complicate flights into deep space, which leads to additional tension and irritability of the crew. At the same time, it is necessary to understand that the training of cosmonauts for orbital flights around the Earth is fundamentally different from an autonomous interplanetary flight.
Labour social isolation of the team of polar explorers, winterers. The main harmful factor, in addition to the isolation itself, is the low temperature and the polar night. At the same time, the number of members in the social group is significant: at large stations, more than fifty people can be present at the same time for wintering. The monotony of snowcovered landscapes, the polar night, and the constant cold, combined with isolation, cause depression and irritability. Over a long time, many studies have been carried out to study this insulation. N. Kanas et al. [4] write about the characteristics of winterers: "Studies conducted among wintering people at Arctic stations show that ideal candidates for long-term missions have a low level of emotional lability, extraversion and consciousness, demonstrate a low need for affection from other people. It may indicate unspecified habituation of a person to the harsh conditions of wintering.
Labour social isolation of the submarine team. In these specific social groups, the main harmful psychogenic factors are lack of daylight, constant exposure to danger, cramped premises, long-term isolation (up to 90 days), and lack of communication with family members. In the studies of K. S. Brasheret al.
[6], psychological tension is considered as stress. 'Occupational stress in divers refers to physical or psychological reactions experienced when workplace stressors exceed the person's ability to cope. Submariners are losing contact with the outside world, both physically and psychosocially. ' It should be noted that submariners, as in a certain sense, the naval elite, are very well trained. During isolation, psychological assistance is provided to the wives of submariners there are so-called "clubs of submariners' wives".
At the same time, in general, the level of training of graduates of military educational institutions (including naval universities) is psychologically weak. Young officers experience difficulties in organizing and conducting educational work with subordinates. Former cadets receive these skills when they come to the service. According to Munik A. A., described in the journal "Scientific Notes of the University named after P.F. Lesgaft" edition of 2019 -No. 9 (175), 78.3% of graduates of military educational institutions have low psychological and pedagogical readiness.
[6] compare the stress of submariners and other members of the Navy. According to several parameters, stress factors have the same effect. The researcher sees such a result in certain training, the presence of complex social ties among submariners, and the high status of the profession. K. S. Brasheret al.
[6] say: 'Most submariners have actively agreed to work in this profession, so there may be a self-selection bias in which submariners are naturally more resilient than those who join the general number of Navy employees and then are called up for work on ships. This increased resilience will help protect divers from the negative psychological impact of working in extreme conditions. ' Labour social isolation of the crew of a ship. Shipwork is quite diverse, depending on the ship itself. Consequently, the psychogenic factors that affect can vary greatly. Social isolation, depending on the ship and its goals, varies both in time (from several days to 7 months) and in the number of crew (from 5 -6 people to 100 people). It has already been mentioned above that the main psychogenic factors for seafarers are: heaving at sea, communication problems, equipment and sea noise. Researchers K. Szymanska et al. [7] in their paper, operates with an indicator of the risk of suicide as a consequence of stress in Polish seafarers during social isolation. "The low proportion of suicides in the total number of deaths at sea among coastal fishermen can be explained by the fact that despite their hard work on ships, the trips themselves are short, and they are regularly and often at home and enjoy close contact with their families". Analyzing the studies of K. Szymanskaet al. [7], we can conclude that everything is determined by the duration of isolation. A person is ready to work under difficult conditions, but for a short time. A. Mellbyeet al. [8] describe similar results, but for English sailors: "Shorter periods of stay at sea and the impact on relationships can lead to a decrease in social isolation. In explaining why 87% of reported suicides between 1976 and 2002 occurred on deep-sea vessels, it was found that the biggest factor motivating seafarers to quit their jobs is "time away from home" as more than 50% of respondents reported this as his biggest problem with sailing." The next important issue relates to communication, both deep-sea and coastal ships. Communication with family members and friends on the Internet for coastal sailors does not cause any special problems, which cannot be said for deep-sea sailors. A. Mellbye et al. [8] cite the data: "In a 2014 study, 76% of respondents identified improved Internet access as the most demanded on-board service". At the same time, A. Melbyeet al. [8] believe it is necessary to distinguish between inshore and deep-sea sailors: "Isolation is something that can be felt by all types of seafarers, evidence indicates that time at sea is an aggravating factor, so it is appropriate to discuss social isolation and the deep-sea travel together". This topic is also being developed by V. Yu.Khotinets et al. [9].
A. Mellbyeet al. [8] touch upon an overriding issue of medicine: the passage of a medical board; identifying sailors with a tendency to depression. "Employers want to have healthy (low-risk) seafarers on their ships, while seafarers often want to get a job (and even financially dependent on employment) regardless of their health. Similar conclusions regarding health and the prediction of psychopathology are described by K. Szymanskaet al. [7]: 'It happens that sailors suffering from mental disorders are hired to serve at sea. In stressful situations, people with the subclinical syndrome of organic brain damage are much more prone to psychological trauma. Therefore, when examining seafarers, tests should be carried out. But the ability to predict and prevent suicide among seafarers during their periodic medical examinations is limited".
In Russia, the situation with psychological preparation is developing quite badly. During a conversation with many seafarers, it was found that psychological training, team-building events, and psychological consultations are practically not carried out. Sailors do not even have elementary psychological skills that help them solve elementary issues in their team. Especially many sailors were surprised by the dynamic theory, which makes it possible to predict the psychological state of the crew members on different days of the trip.
Labour social isolation of teams of specialists working on a rotating scheme. Many social psychologists argue that specialists working on a rotational basis cannot be classified as work collectives working in isolation. But these social groups are subject to similar influences. A rotating scheme is a special form of carrying out the labour process outside the place of permanent residence of workers when their daily return to the place of permanent residence cannot be ensured. Usually, rotational work is carried out in climatically unfavourable regions of the country, where it is impossible to find specialists in various professions due to the low population density.
These social groups work cyclically, that is, on a schedule from 15 days to a year. Brigades of "shift workers" live near work in specially equipped shift camps. Typically, the duration of the workday (shift) of the employees is 12 hours. Shift camps are a complex of residential, sanitary, cultural, and household and utility buildings and structures designed to ensure life, i.e., short-term residence of workers. Potentially, an employee can find a fairly extensive communication, i.e., join an informal group, but in reality, it is more difficult. In shift camps, the number of residents -"shift workers" can reach up to a thousand people, but a person communicates, in most cases, only with their team because they live and work with the same people. It is this kind of brigade settlement that exists in most shift camps. Cultural leisure in these villages is usually very limited. At the same time, in settlements, there are internal rules for the behaviour of workers, especially regarding the use of alcoholic beverages. Walking is the most popular activity.
The issue of workers' health is quite complex. K. Szymanskaet al. [7] have been considered the problem related to health and the passage of medical examinations by seafarers. Shift workers have a similar problem. While passing the medical board, an employee can often conceal their actual health status, which can then affect the future. The employee strives to keep this job in any way because, for the most part, workers live in small towns, villages, and settlements, where it is not possible to find a well-paid job. This forces them to look for work with a shift work organization.
Labour social isolation of the collectives of special-purpose railroad cars. Specialpurpose railroad cars are mobile units created on the basis of passenger cars with special measuring equipment installed on them. When it moves along a railway track, certain parameters are diagnosed. There are many different classes and types of special-purpose railroad cars. Depending on the class and type of a railroad car, railway parameters are taken exclusively for this class of a railroad car. Among many organizations of Russian Railways, Special-purpose railroad cars are called differently: automated diagnostic systems (ADS), or mobile diagnostic tools (MDT). Further in the article, special-purpose car will be called ADS. ADS includes the following special-purpose cars: complex car ADS-I "ERA"; track geometry car KVL-P; detector car; rail lubricator-car.
In terms of everyday life, ADS, as a rule, have living quarters (compartments), a kitchen, a toilet, a workroom (saloon-office) with a workshop. ADS has to combine the function of an accommodation unit and work "on wheels". The energy autonomy of the ADS is provided using: a diesel-electric installation available on board or on-board batteries. The autonomy of water supply is ensured by the supply of water in the tanks. In winter time, the ADS is heated with solid fuel or a heating burner with light diesel fuel.
As mentioned above, all ADSs are complex and different, both in terms of diagnosing various parameters of railway track, and in terms of operation. But what unites them all is that they almost constantly move by rail. Given the specifics of the ADS work, the question arises about the special aspects of the work of the labour collective (crew). The main factors affecting the team are: social isolation; work with a high duration of a working day; night work, high temperature work in summer.
Work on ADS is proceeded as follows. ADS is served by two teams: the first and second shifts. Each team works 15-16 days a month. There are ADS, where the team works 30-31 days, and then rests for a month. On the appointed day, the shift of the ADS teams is carried out. Depending on the ADS, the number of people in the team ranges from 3 to 7.
The discussion about the fact of the existence of social isolation in the ADS teams arises. Is it possible, in general, to consider social isolation in ADS collectives as isolation? After all, the isolation to which the collective is subjected is "incomplete", or, more correctly, "partial". Partial social isolation is isolation in which the team can sometimes leave the isolated environment, or communication with people outside the isolation is possible. Employees of Russian Railways from other organizations enter the ADS teams, a closed (isolated) system, for official needs. Collective members can leave isolation when the ADS is standing on a station and not moving. For example, an employee can go to a store at certain stations, or on official business. But, in reality, the opportunity to walk happens only two or three times per shift (considering that a shift takes 15 days).
To answer this question, we will use research conducted in two organizations. To answer this question, we will use research conducted in two organizations. The first is the "Infotrans" training center (Samara). The second organization is the North Caucasian branch of the Rostov Center for Diagnostics and Monitoring of Russian Railways (hereinafter RCDM). Methods and procedures for conducting research differed. In the studies of "Infotrans" only author's questions were used. In the studies conducted in the teams of the RCDM, both author's questions and various methods were presented. As a starting point, let us consider the difference in research conditions between "Infotrans" and "RCDM". Let us compare the differences in the results of the answers provided to some author's questions of the "Infotrans" specialists from the answers of the "RCDM" specialists.
The "Infotrans" training center provides training for ADS specialists, namely, only employees of track geometry cars from the Russian Railways road network. This survey took place during classes, that is advanced training, upon arrival of a specialist for training in Samara. 71 specialists of the ADS (track geometry car) took part in the survey. Specialiststrainees were presented with author's questions in the amount of 78. Questions are devoted to both the technical condition of the ADS (track geometry car) and its mode of operation, as well as the psychological characteristics of working in a team. The possible answers are: "absolutely agree"; "agree"; "refrained"; "disagree"; "totally disagree".
The study of the RCDM of the North Caucasian Russian Railways, was conducted among specialists: KVL-P track geometry car; detector car; rail lubricator-car. When questioning the specialists of the RCDM, the research was carried out more thoroughly: the operational order No. 273/RCDM dated 23.08.2021 was officially issued, signed by the head of the RCDM, A. V. Kruglov. A total of 32 people took part in the study. The research was conducted in the form of a conversation right at the workplace, that is in ADS. The ADS specialists were provided with 10 author's questions, similar to the questions in "Infotrans". Specialized methods were also involved in the research.
Let us compare the results of answers to some of the author's questions regarding social isolation. We will provide answers in tabular form, both from the specialists of the "RCDM" of the North Caucasian Russian Railways, and from the specialists of "Infotrans". Response data is given as a percentage.
The first question concerns the direct impact of isolation, namely the constant stay on watch (table 1). As one can see, the results of the answers are quite diverse, both from the specialists of "Infotrans" and "RCDM". The received response data does not depend on the ADS, whether it is a track geometry car or a detector car. The results are due to the subjective opinion of the specialist oneself. Similar answers can be seen in the next question (table 2). As it was said before, everything depends on the individual perception of the specialist oneself. The results of the answers to the next question show that, in fact, there are situations of isolation in which a person cannot leave their workplace ( Table 3). The answers show the presence of social isolation in almost all types of ADS. The final question concerns the relationship of work in a special-purpose railroad car to extreme work (table 4). The results of the answers are purely subjective, because social isolation in combination with other domestic and labour difficulties forms the answers to this question.  Conclusion: after analyzing the answers to the author's questions, we conclude that ADSs, such as track geometry cars, detector cars, rail lubricator-car, are labour collectives where one has to work in specific conditions of social isolation and other additional difficulties. These additional difficulties are the working conditions and rest conditions of the ADS itself, as described above, as well as many other conditions.

Results
After considering isolated labour collectives, describing the specifics of work and life, letus move onto the classification of social isolation. It is necessary to consider many objective factors. The psychogenic and social factors that arise in labour activity are summarized in the table (table 5). The assessment was carried out subjectively. At the same time, when assessing the same factor in different professions, the same assessment was often made, although the difference in the impact of this factor is very large. The assessment was carried out on a fourpoint scale. The maximum of the harmful factor is "+++", and to the minimum is "+". The absence of a factor is "-".
Based on the table above, it is possible to classify all labour social isolations into two types. The first type is deprivation social isolation. The second type is irritable social isolation. Let us give a brief description of these isolations.
Deprivation social isolation is a fairly severe social isolation, in which a person has a strictly limited social circle, which does not exceed 3-7 people. In this isolation, there are: deprivation, impaired perception, information exhaustion of people in a group (colleagues become uninteresting), a person has a sharply limited flow of personal information. In addition, there are additional psychogenic factors: weightlessness for astronauts, lack of sunlight for submariners, a constant sense of danger, and others. Space station and submarine collectives are subjected to this type of isolation.
Irritable social isolation is more common. The main difference from deprivation isolation is the number of members in the group (from 7 to 200 people) and the milder working and living conditions of a group. With this isolation, a person can easily find communication and form an informal subgroup, that is the choice is extensive, and finding oneself a fellowship is always possible. The main irritant comes from many other psychogenic factors: the difficulty of communicating with friends and family members outside the circle of isolation, in most cases only via the Internet; difficult working and rest conditions; monotony; limited social environment, and others. Such isolation is most common in the organization of work on a rotational basis, where a person has a job with a long working day (from 8 to 12 hours). At the same time, there is a fairly rich circle of contacts that an employee can find among numerous colleagues.
As mentioned above, irritable social isolation can be classified into complete and incomplete (partial). Incomplete social isolation is understood as isolation in which an employee can leave isolation for a short period of time, from an hour to several days. As an example of such partiality, we mention the possibility of some sailors to leave the ship and spend the night at home, that is have a short respite (for day or two), when the ship enters the port for a short stay. Partial irritable social isolation can also be attributed to the collectives of the ADS of OAO "Russian Railways" with a duration of partial isolation of 15 days.

Discussion
After the classification of labour social isolation into two subgroups: derivational and irritable, the question arises of the possibility of applying the classifications. It has been repeatedly mentioned that irritation or depression due to social isolation affects a person in a complex way and depends on many factors: isolation itself, climatic conditions, length of the working day, number of members in a social group, duration of isolation, and others. Therefore, one can go further and create a "passport of labour social isolation".
In the work of N. N. Simonova in the "Izvestia of the Samara Scientific Center of the Russian Academy of Sciences" journal, issue No. 4, 2009, a classification is made according to the degree of isolation of oil workers during rotational work in the north: «1) employees working and living in the shift camp (about 200 people) -a low degree of isolation; 2) oil field (30 -40 people) -a medium degree of isolation; 3) remote rig workers (about 15 people) -a high degree of isolation». Consequently, when classifying, the author starts, first of all, from the number of members in a social group and from a "superficial" indication of working and rest conditions. Further, in her work, N. N. Simonova repeatedly indicates the degree of isolation: low (200), medium (40), high (15). The numbers in brackets are the number of members in the social group. We can make a conclusion that N. N. Simonova classifies by the degree of isolation, first of all, by the number of people in the group. N. N. Simonova gives a certain "passport" of the schedule of work and rest of all three degrees of isolation -SWR (schedule of work and rest) 12*12; 52 + 52 -that is12 hour work shifts with a shift duration of 52 days followed by 52 days of rest. But this classification has many limitations, because it characterizes only rotational work, where the main criterion is the number of members in a social group.
When creating a "passport of labour social isolation" (hereinafter PI), it is necessary consider both labour, household, organizational factors, and social ones. These factors of social isolation of the group can be divided into three components: 1. external factors. External factors include the environment in which a social group lives and works. Here we include: conditions of stay (climatic, temperature, isolation specifics), special aspects of work activity, availability of household and industrial amenities; 2.
organizational and production factors. These factors include: a duration of the shift itself and a duration of rest at home in days (example: 90/60 -90 days of shift and 60 days at home), work and rest schedule (SWR), an indication of the work schedule for the night shift. Here it should also be pointed out the possibility of early termination, or extension of isolation, that is its duration may be less or more than the calculated period. The unexpected news about the increase in isolation may additionally affect both production tasks and the psychological dynamics of a social group. These factors include: what kind of isolation is present -deprivational, or irritable, and complete, or incomplete. 3.
socio-psychological factors. These factors include: size of a social group, cohesion of a group, psychological readiness, presence of leadership qualities in a leader of a social group.
To create a PI, it is necessary to list all the factors in sequence and thereby identify a social group as much as possible. First, we will enter external, then organizational-production and socio-psychological factors into a PI. For clarity, we give examples: «The ship has a displacement of 12,000 tons, built in 1982, OH-2020, class A, river-sea, working conditions are tolerable, the maximum (minimum) temperature in the premises is 32 (16), the crew lives by: 5 (1); 2(2); 1 (3). Duration of the watch is 90(60) it is possible to increase (decrease) the watch no more than ± 4, isolation: irritable (complete). SWR-4-8, night work. 12 people, the crew is poorly trained, psychologically unstable, the leader does planned duration of a watch. Example: the total duration of the watch is 90 days, followed by a rest at home for 60 days, and at the moment the watch lasts 45 days.

Conclusions
In this article, we reflected the problem of labour social isolation. Many different examples of social isolation were given. We came to the conclusion that each profession, where there is social isolation, has additional psychogenic factors. We have listed professions in which there is social isolation. The description of each labour social isolation in these professions were given. Psychogenic factors in such exotic professions, together with isolation, have an irritating effect on human psyche. It was also said about a duration of social isolation. All these complex factors have made it possible to create a classification of labour social isolation according to the following factors: duration of isolation, specifics of labour activity, size of a group, and many other factors. The created classification of labour social isolation allows us to rank them according to the irritating effect on psyche. All social isolations were divided into two subgroups: deprivation and irritable social isolation. Irritable social isolation can be complete -that is without the ability to leave a social group, and partial (incomplete) -with the ability to leave a social group.
By conducting empirical research in the teams of special-purpose railroad cars of Russian Railways, the fact of the existing social isolation was proved. Isolation was classified as irritable (incomplete), with the duration of 15 days. This isolation of special-purpose railroad cars was included in the general table of extreme professions with an isolation factor.
Using the obtained classification, the passport of isolation was created. It allows to describe the conditions in which the social group works and lives, and to give characteristics to the group itself, in a few sentences. This isolation passport consists of three factors: external, organizational and production, socio-psychological. External factors in an isolation passport show: in what conditions (locality) a group works, what climatic and weather conditions a team faces. Organizational and production factors reflect organizational issues: length of a working day, work on a night shift, duration of isolation, duration of rest at home. Socio-psychological factors show size of the social group (number of people), group cohesion, leadership problems in a group. Although this technology cannot reveal all the relationships in the group, it can serve to improve working conditions, psychological climate in teams. In addition, it can prevent negative consequences of isolation. The technology can be further improved.
