Automated information system for testing helicopters equipped with night vision systems based on diagnostics of the functional state of the crew

The subject of the study is the problem of ensuring optimal conditions for interaction between humans and aviation equipment in the interests of ensuring its safe operation, which has recently become more acute. Based on studies of the pilot's activity obtained during flight tests of helicopters equipped with night vision goggles, it is shown that the use of night vision goggles imposes special requirements on the organization of attention distribution, spatial orientation and is accompanied by an increase in the level of nervous and emotional tension. The main results of foreign developers on the improvement of night vision systems related to the introduction of technical vision systems on helicopters are described. It is proved that for an objective examination of such systems in flight tests, it is necessary to create a special automated information system. The developed automated information system provides the collection and processing of flight information during flight tests using intelligent sensors for monitoring and recording the biometrics of crew members and an image recognition system. It will allow recording, processing and accumulating flight and psychophysiological information in real test flights during the implementation of the entire flight test program, providing specialists in the field of aviation medicine and ergonomics with objective quantitative characteristics of the studied parameters when testing promising night vision systems of combat helicopters. It is shown that the introduction of modern information technologies into the process of testing aviation equipment allows objectively and with high accuracy to analyze and evaluate the content and psychophysiological structure of the pilot's activity based on a comparison of changes in flight parameters, the movement of controls, the direction of the pilot's gaze and his psychophysiological characteristics and recommend for practical use specific variants of night vision systems.

Risks of health disorders in pedagogical, medical workers and preventive measures

The formation of a healthy lifestyle and a healthy lifestyle in the work of various activities, developing a program that includes appropriate measures to correct the functional state of employees of nervous and emotional labor, is currently one of the essential areas of occupational health. The study aims to assess the prevalence of behavioral risk factors for health disorders and the effectiveness of measures to correct overstrain in pedagogical and medical workers, depending on the personal level of anxiety. The researchers conducted comprehensive physiological and hygienic studies. We described behavioral risk factors, awareness of health-saving issues based on a questionnaire (346 teachers), a professional graphical assessment of the intensity of efforts. Psychophysical studies help to study the states of various functions of the central nervous system and the cardiovascular system, psychological testing, and general physical performance (GPP) according to the RWC170 test when evaluating the implemented model of motor activity and assess the effectiveness of relaxation in the shungite room. We performed static processing of the data obtained using statistical programs EpiInfo 3.5.2., Statistica 10, Microsoft Excel 2010 using adequate methods of statistical analysis. The study of the prevalence of the factors risky cheek of life for the health of teachers revealed insufficient physical activity (61.1% (95% CI 54.7-67.2)), inadequate sleep duration (46.1% (95% CI 40.0-52.4)), eating disorders (16.2% (95% CI 11.9-21.5)) tobacco smoking (15.8% (95% CI 11.5-20.9)). The developed and implemented regime, which increases the volume of motor activity to 8-9 hours a week instead of 3-4 hours, contributed to an increase in resistance to stress effects, a decrease in the percentage of identified teachers with a low level of physical fitness. A high degree of nervous and emotional tension in the work of general practitioners, the possibility of infection with COVID-19 leads to the formation of a high level of anxiety in a significant part (63.7-72.2%) of medical workers, which indicates the purposefulness of a psychological correction measure. The conducted production studies have shown the usefulness of using in programs for correcting the functional conformity of pedagogical and medical workers, an increase in motor activity using physical culture and sports, and relaxation in the shungite room.

Sleep Quality and Related Determinants among Stroke Patients: A Cross-Sectional Study.

Objective: Effective rehabilitation and better quality of life among stroke patients are functions of several factors such as quality and pattern of sleep. The present study aimed to evaluate sleep quality and related determinants in such patients. Method: The present cross-sectional study was performed from October to December 2019 among stroke patients who were admitted to Sina Hospital, Hamadan, Iran. We used the Pittsburgh Sleep Quality Index (PSQI) questionnaire to determine sleep quality in these patients. Significant determinants of the global score of PSQI were identified via multivariable linear regression. Results: A total of 97 stroke patients (age 67±79 years, 55.7% male) were enrolled into the study. Prevalence of poor sleep was 0.84 (95% CI: 0.75, 0.91) in stroke patients. Patients with nervous tension and those with surgical treatment and with Non-hemorrhagic CT scan had a predicted increase of 1.65, 2.91 and 3.25 in the mean of the global PSQI score (P ≤ 0.05), respectively. Conclusion: Nervous tension, treatment method, results of CT scan and cardiac problems may be associated with post-stroke sleep disorder.

THE INFLUENCE OF THE LATEST SOCIETY CHALLENGES ON DIFFERENT INSTRUCTIONAL PROGRAMS FOR SPECIAL EDUCATION TEACHER TRAINING IN THE USA

The aim of this work was to study the impact of the latest challenges of the globalized society on special education teacher training in the United States and Ukraine. For the needs of our research current instructional programs 13.1013 – Education/Teaching of Individuals with Autism and 13.1008 –Education/TeachingofIndividualswithOrthopedicandOtherPhysicalHealthImpairments that are used for the US educators’ preparation were proposed as examples. The global onset of the COVID-19 pandemic has changed the common lifestyle for the majority people. Constant uncertainty, social distancing, enormous off-schedule work and distance learning in the face of changing external constraints create an atmosphere of nervous tension that undoubtedly affects all people, but people with disabilities can be observed as especially vulnerable to these and other challenges. The researchers report symptoms of anxiety and depression among young people, feeling of having been left out of the society. There is no doubt in the necessity to support vulnerable students' mental health normalization mostly by psychologists and teachers. In order to adapt to innovations, educators should unite in professional pedagogical associations and become "agents of change". With the reference to the recommendations of the Council for Exceptional Children and scientific researches, the paper describes the list of professional skills a special teacher needs to obtain in the current conditions. Due to distance learning conditions teachers of students with autism should be able to take into account factors of social interaction and possible behaviours and communication that can affect the effectiveness of educational activities online. Together with proper arranging of classroom furniture and assigning seats, teachers of students withorthopedicandotherphysicalhealthimpairments should gain the skills of effective online communication, tailoring instructional methods, using technical and non-technical educational tools, and recognizing physical condition of a student for proper combining different academical tasks and physical exercises.

EFFECT OF LAVENDER OIL MASSAGE ON PAIN PERCEPTION DURING FIRST STAGE OF LABOUR AMONG PRIMI PARTURIENTS

STATEMENTA study to assess the effect of lavender oil massage on pain perception during first stage of labour among primi parturients admitted in selected hospital, Lucknow. Introduction: Pain in labor is a nearly universal experience for child bearing women. Labor pain is a challenging issue for nurses designing intervention protocols. Pain during labor is caused primarily by uterine muscle contractions and somewhat by pressure on the cervix. This pain manifests itself as cramping in the abdomen, groin, and back. Other causes of pain during labor include pressure on the bladder and bowels by the babys head and stretching of the birth canal and vagina. Labor events have got great psychological, emotional, and social impact to the women and her family. She experiences stress, physical pain, and fear of dangers. The care giver should be tactful, sensitive and respectful to her. Throughout labor she is given continued encouragement and emotional support and assurance are given to keep up the morale.Lavender oil used for aromatherapy is a very versatile essential oil that can be used throughout labour to promote relaxation. It provides a sedation effect to the central nervous system and relieves headache, nervous tension and balances mood swings. According to the American Pregnancy Association, lavender can help create a tranquil, relaxing atmosphere which can reduce pain and stimulate contraction of uterus Objectives Of The Study: 1. Assess the effect of lavender oil massage on pain perception during first stage of labour among primi parturients of experimental group. 2. Compare the post test level of pain perception between primi parturient of experimental group and control group. 3. Associate the level of pain during first stage of labour among primi parturients of experimental group with selected demographic variables. Research Methodology: This study was conducted using Quantitative approach at Integral Hospital, Lucknow. Quasi experimental research design (post test with control group design) was used in the study. The conceptual framework used in this study was Callista Roys Adaptation Model (1991). The total sample size was 30 (15 in experimental group and 15 in control group) selected by convenience sampling technique. Demographic variables were obtained by structured interview and the level of pain was assessed by modified visual analogue scale Reults: The data obtained are tabulated and analyzed using descriptive and inferential statistics. The statistical analysis of the data showed that the mean post test level of pain perception in control group is higher than the mean post test level of pain perception in experimental group. The mean score of experimental group is 2.2(68%) with SD0.41and mean score of control group is 2.8(88%) with SD 0.35 the mean difference is 0.4. The calculated t value is 4.31 at p<0.05 which is more than the table value at 0<0.05. Therefore the null hypothesis H01 is rejected. So the research hypothesis H1 was accepted Conclusion: The findings revealed that there was a significant difference between the level of pain perception among experimental group and control group. It also showed that there was no association of the level of pain during first stage of labour among primi parturients of experimental group with selected demographic variables.

Influence of the nervous and emotional tension of the labor process on the body of pedagogical and medical workers

Introduction. The impact of high information and neuro-emotional loads on teachers and medical workers contributes to professional stress and the development of production-related diseases. The development of preventive programs in health-saving behavior is quite relevant. It reveals the need to study the peculiarities of the labor activity in employees of pedagogical labor and the medical sphere. The study aims to substantiate hygienic and medical-preventive programs to prevent the development of overstrain and maintain health in pedagogical and medical workers with different work intensities. Materials and methods. Researchers carried out comprehensive physiological and hygienic studies, a hygienic assessment of the intensity of the labor process, and factors of the production environment. We have a questionnaire survey and the results of medical examinations of teachers and surgeons. Scientists did physiological studies on the state of the cardiovascular system with characteristics of the response to stress loads (ECG recording on a 12-channel electrocardiograph and continuously using Holter monitoring, determination of systemic blood pressure). We calculated the total risk of fatal cardiovascular complications on the SCORE scale. Researchers carried out statistical processing of the obtained data using the statistical program EpiInfo 3.5.2., Statistika 10, Microsoft Excel 2010. Results. 85.7% of medical university teachers have chronic diseases, and diseases of the circulatory system prevail in the structure of morbidity, the frequency of which increases with age. The results of the questionnaire survey established the priority behavioral risk factors for teachers. There is a high (from >5% to 10%) and very high (>10%) absolute risk of fatal cardiovascular complications on the SCORE scale in teachers. In surgeons, the study of the features and degree of adequacy of the cardiovascular system's response to stress during work revealed the tension of the regulatory mechanisms of the circulatory system, which indicates a decrease in the functional capabilities of the myocardium. Conclusions. Neuro-emotional stress of work is the leading professional factor in the teaching staff of higher medical education (2 permissible, 3 class of harmfulness of the 1st degree) and surgeons (class 3.2). It determines the formation of the functional state of neuropsychiatric tension.

Ni and Cr impurities profile in Valeriana officinalis L., radix-based herbal medicinal product available in polish pharmacies due to ICH Q3D guideline

Elemental impurities (EIs) profiling in final pharmaceutical products is often not adequately treated, however it is crucial problem in pharmaceutical analysis by reason of the various regulatory authorities (like ICH Q3D guideline). EIs in pharmaceuticals may arise from numerous sources of which the herbal ingredients are not a frequent subject of pharmaceutical analyses. However, based on number of traditional use registrations per year for herbal medicinal products (HMPs) in the EU, it can be stated that monocomponent HMPs are still very popular for use. Due to the high frequency of use, exposure to EIs from HMPs may be high during long-term use. The aim of our article was Ni and Cr impurities profiling of Valeriana officinalis L., radix (Valerian root) as an example of the HMP available in Polish pharmacies for the relief of mild nervous tension and sleep disorders. The choice of metals was justified by: (1) a single dose of Ni administered via oral route can induce dermatitis in nickel-sensitised individuals; (2) Cr is a very problematic element from toxicological point of view. Our results indicate that the standards of the ICH Q3D guideline are met for all EIs.

The Toxicological Risk Assessment of Lead and Cadmium in Valeriana officinalis L., radix (Valerian root) as Herbal Medicinal Product for the Relief of Mild Nervous Tension and Sleep Disorders Available in Polish Pharmacies

Studies related to the toxicological risk assessment (TRA) of heavy metal impurities (HMIs) in pharmaceuticals are an important issue but there is a lack of refereed literature around the safety of Valeriana officinalis L., radix (Valerian root) as herbal medicinal product (HMP) for the relief of mild nervous tension and sleep disorders according to lead and cadmium impurities. The aim of the study was to estimate the TRA of lead and cadmium in Valeriana officinalis L., radix (Valerian root) as HMP (n = 5) available in Polish pharmacies. In the case of herbal pharmaceuticals, it is particularly important to control the level of HMIs accumulated during the plant’s growth. Perhaps, the exposure for a single dose is not relevant; however, justification of our studies is a fact that herbal therapies are usually long term. Therefore, even small HMI doses as present in particular plant may accumulate in patient body over a long period of time. Levels of lead and cadmium were measured by electrothermal atomization atomic absorption spectrometry. The levels of lead and cadmium as HMIs (independently of the producer and declared composition) are quite similar. Our results are satisfactory, confirming the safety of Valeriana officinalis L., radix (Valerian root) as herbal medicinal product for the relief of mild nervous tension and sleep disorders available in Polish pharmacies according to ICH guideline Q3D. To the best of our knowledge, this paper is the first study about lead and cadmium content as HMIs in HMP containing Valeriana officinalis L., radix (Valerian root).

THE EMPIRICAL RESEARCH ON STRESS COPING STYLES

Problem statement. The article presents the theoretical and empirical research of three stress coping styles: adaptive, relatively adaptive, maladaptive. The special attention is paid to the empirical study on each style components: personal reactions to stress, psychological defence, endurance under aggressive work conditions and threats to life, fast resources recovery after stress, ability to build partnerships, responsibility and determination, a set of adequate reactions to stress. Objective. To carry out an empirical research of police patrol officers’ stress coping styles. Research Methods. The diagnostic base included the following methods: E. Heim’s method examining coping strategies, “Don’t let a person fall” express-diagnostics of A. Smirnova (projective technique), “Assessment of nervous and mental tension” of T. Nemchin, “A person under rain” (projective technique) of A. Romanova and T. Sitko, the inquirer of the social-psychological adaptation of C.Rogers and R.Diamond, “Transactional analysis of communication” of E. Ilyin. Research results. Most respondents with adaptive style of stress overcoming in extreme conditions apply successful coping strategies (66%), they quickly recover lost resources, are prone to partner communication, responsible, show leadership qualities, find a way out of situations and are able to lead others, feel protected in a stressful situation, are able to perform duties under aggressive working conditions, rarely get into critical situations because they always carefully calculate all possible variants of events and try to foresee everything that can happen, in a critical situation they are not confused and can do everything necessary to correct what has happened. Patrol officers with the maladaptive style are unable to work in extreme working conditions, feel unprotected in aggressive conditions, and react to stress naively and timidly.

Occupational diseases of builders and factors affecting their occurrence and development

The article deals with individual professional diseases of builders and the factors that influence their occurrence and development. The author believes that a wide range of industrial activities of representatives of the construction professions and the impact of the environment plays a vital role in the development and progression of most occupational diseases. However, the harmful effects of these diseases on the body are greatly underestimated, which reduces the effectiveness of preventive measures and complicates treatment. It is also impossible to ignore the occupational diseases of drivers of construction vehicles. The most common of them are diseases associated with the development of cardiovascular pathology, neuropsychiatric disorders, gastrointestinal disorders, diseases associated with problems with the musculoskeletal system, disorders caused by a sedentary lifestyle, as well as allergic and oncological diseases. In addition, drivers are affected by harmful sanitary and hygienic factors: noise, vibration, high temperature, harmful impurities in the bus cabin, nervous tension. Taking into account all the above factors, it is necessary to carry out appropriate prevention of occupational diseases of representatives of construction specialties by conducting educational work and conducting regular medical examinations.

The classification is given to the expressive forms in which emotions are clothed, allowing to determine the signs of nervous tension and overwork.As a result of the survey conducted among students, the main stress-generating elements that exist, in their opinion, in the educational process were identified, which made it possible to develop recommendations, the introduction of which into the educational process, stabilized the psycho-emotional state of students in the experimental group in comparison with the control group, in which by the end of the year the leading indicators worsened.

Nano-poetics and a nano-representation of the Israeli milieu in Yossel Birstein’s short-short bus-stories

ABSTRACT This article discusses the unique nano-poetics and its nano-representation of the Israeli milieu, as found in Yossel Birstein’s short-short bus-stories. While these stories demonstrate the author’s poetics, they also constitute a miniature replica of Israeli society, emphasising the following four major aspects of this society: (1) the tension between the Jewish past and the Israeli present; (2) the complex dynamics between private and public life; (3) the gap between newcomers and veteran immigrants; and (4) a mentality dominated by nervous tension combined with the unique form of audacity known as chutzpah. Birstein presents the bus both as the inspiration for and as the object of his writing, and this narrative framework showcases the many variants in Israeli culture.

Updating the biological interest of 'Valeriana officinalis'

Valeriana officinalis L. (Caprifoliaceae) has been traditionally used to treat mild nervous tension and sleep problems. The basis of these activities are mainly attributed to valerenic acid through the modulation of the GABA receptor. Moreover, V. officinalis is claimed to have other biological activities such as cardiovascular benefits, anticancer, antimicrobial and spasmolytic. The current review aims to update the biological and pharmacological studies (in vitro, in vivo and clinical trials) of V. officinalis and its major secondary metabolites in order to guide future research. Databases PubMed, Science Direct and Scopus were used for literature search including original papers written in English and published between 2014 and 2020. There have been identified 33 articles which met inclusion criteria. Most of these works were performed with V. officinalis extracts and only a few papers (in vitro and in vivo studies) evaluated the activity of isolated compounds (valerenic acid and volvalerenal acid K). In vitro studies focused on studying antioxidant and neuroprotective activity. In vivo studies and clinical trials mainly investigated activities on the nervous system (anticonvulsant activity, antidepressant, cognitive problems, anxiety and sleep disorders). Just few studies were focused on other different activities, highlight effects on symptoms of premenstrual and postmenopausal syndromes. Valeriana officinalis continues to be one of the medicinal plants most used by today's society for its therapeutic properties and whose biological and pharmacological activities continue to arouse great scientific interest as evidenced in recent publications. This review shows scientific evidence on traditional uses of V. officinalis on nervous system.

Стресс и питание

In recent years, there has been a tendency to identify stress with nervous tension, but stress is not only a reaction to unpleasant experiences or conflicts but also a general adaptation syndrome. All factors (of the external and internal environment) that affect homeostasis cause a stress reaction that is implemented in several stages. And anxiety, the purpose of which is to mobilize resources, is an important stage of this process. It is necessary to maintain homeostasis and adapt the body to new conditions. The ability of the body to properly allocate reserves and adapt to stress is called stress resistance. In case of prolonged stress, anxiety becomes pathological leading to adaptive reserve depletion, and, consequently, stress resistance decreases and vulnerability to any stressful factors increases. Could nutrition reduce anxiety and increase stress resistance? What adaptation mechanisms are damaged by regular improper nutrition? In this article, we tried to answer these questions. Regular consumption of certain foods creates favorable conditions for adaptation, reducing the burden of the stress consequences. A healthy lifestyle, including proper nutrition, exercise, rest and the development of positive coping skills, can significantly change the ability to adapt, increase stress resistance and minimize the stress effects. KEYWORDS: food, stress, anxiety, stress resistance, homeostasis, adaptation syndrome. FOR CITATION: Akarachkova E.S., Belyaev A.A., Kadyrova L.R. et al. Stress and nutrition.
