Background. An imbalance of interaction between the sympathetic and parasympathetic links of the autonomic nervous system leads to autonomic dysregulation of the heart rate resulting in insufficient stress resistance, impaired adaptation and depletion of the protective mechanisms of the gastric mucosa. Therefore, the purpose of our research was to study adaptive potential of the body depending on the aggressive and protective factors of the gastric juice. Materials and methods. Seventy-one patients with esophagogastroduodenal pathology were examined using the method of PRECISE-diagnostics. The level of pH, pepsin, glycoproteins, fucose and sialic acids in the gastric contents was determined. The patients were divided into 3 representative groups: I — 30 individuals with hiatal hernia; II — 20 patients with achalasia cardia; III — 21 people with duodenal ulcer disease complicated by stenosis. Results. An imbalance of sympathetic and parasympathetic links of autonomic system was detected in 85.2 % of patients. The sympathetic mechanisms dominated in 71.3 % of cases. At the same time, most patients with achalasia cardia had vagotonia. The adaptive and compensatory mechanisms were identified after studying the relationship between the aggressive and protective factors of the gastric mucosa. When analyzing the correlation of aggressive and protective factors of gastric juice, the following adaptive and compensatory options were revealed: 1) hyperreactive, with simultaneous increase in the factors of both aggression and protection; 2) compensatory (an increase in the level of aggressive factors against the background of normal protective indicators); 3) decompensatory (an increase in the level of aggressive factors simultaneously with a decrease in protective factors). Conclusions. The adaptive potential of the body in 85.2 % of surgical patients, mostly those with hiatal hernia and achalasia cardia, according to PRECISE-diagnostics was defined as reduced, in the form of impaired adaptation in decompensatory type of the relationship between aggressive and protective factors of gastric juice.

Relevance: the problem of human adaptation acts as a link in interdisciplinary research. Purpose of work: analysis of the relationship between the psychological and physiological parameters of the adaptive potential and the state of the body in rescue firefighterswith different length of service. Materials and methods: 235 male rescue firefighters aged 25 to 45 years with a service record of 1 to 22 years took part in the study. All subjects were divided into three groups depending on the length of service. For psychodiagnostic evaluation, the adaptability questionnaire was used. The objective physiological criteria for the state of the organism were the indicator of the adequacy of the regulatory processes and the stress index of the “Heart rate variability” method. Results: in the structure of personal adaptive potential, neuropsychic resistance among rescue firefighters of all groups corresponded to high values at the beginning of the shift with a slight decrease by the end of the shift. The adequacy of the regulatory processes and the stress index at the beginning of the shift reflected more pronounced vagal influences in groups with 1–6 and 16–22 years of service compared to the group of 7–15 years of work. At the end of the shift, an increase in parasympathetic activity was found in all groups. Correlation analysis revealed statistically significant relationships between psychodiagnostic and electrophysiological parameters in individuals with experience from 7 years to 22 years. Conclusions: in the groups of experienced rescue firefighters, a more pronounced correspondence of the self-assessment of the level of personal adaptive potential with physiological correlates was revealed compared with less experienced ones.

Low Activity

It was found that in patients with chronic atrophic gastritis, low gastric secretory functions are present in the localization of atrophy in the mucous membrane of the body of the stomach with a tendency to decrease in indices as the degree of atrophy increases and are not associated with the presence of disregenerative changes in the gastric mucosa (intestinal metaplasia and dysplasia). Reduced levels of pepsin in gastric juice and reduced levels of pepsinogen in the mucous membrane of the body of the stomach reliably reflect the presence of severe atrophy of the mucous membrane of the body of the stomach. However, neither the concentration of pepsinogen in the tissues of the mucous membrane of the body of the stomach nor the level of pepsin in the gastric juice make it possible to differentiate the degree of atrophy of the gastric mucosa. The most profound disregenerative changes in gastric mucosa such as colonic metaplasia or dysplasia were detected, accordingly in 18,4 and 10,5% of patients. The presence of intestinal metaplasia or dysplasia causes a low activity of pepsinogen-pepsin. It worth noting that in case of the presence of intestinal metaplasia and dysplasia there is a significant difference between indicators of the concentration of pepsinogen-pepsin and those at patients with chronic gastritis, but without disregenerative changes of the mucous membrane. Also was found an association between the severity of disregenerative changes in the gastric mucosa and the degree of the reduction of pepsin-forming function.

Abstract. Exposure to traumatic events and the associated risk of developing Posttraumatic stress disorder (PTSD) symptoms is a significant and overlooked concern in the college population. It is important for current research to identify potential protective factors associated with the development and maintenance of PTSD symptoms unique to this population. Emotional intelligence and perceived social support are two identified protective factors that influence the association between exposure to traumatic events and PTSD symptomology. The current study examined the mediating role of social support in the relationship between emotional intelligence and PTSD symptoms. Participants included 443 trauma-exposed university students who completed online questionnaires. The results of this study indicated that social support mediates the relationship between emotional intelligence and reported PTSD symptoms. Thus, emotional intelligence is significantly associated with PTSD symptoms and social support may play an integral role in the relationship between emotional intelligence and PTSD. The current study is the first to investigate the role of social support in the relationship between emotional intelligence and PTSD symptoms. These findings have important treatment and prevention implications with regard to PTSD.

The relationship between body height and body weight has been described by using various terms. Notable among them is the body mass index, body surface area, body shape index and body surface index. In clinical setting the first descriptive parameter is the BMI scale, which provides information about whether an individual body weight is proportionate to the body height. Since the development of BMI, two other body parameters have been developed in an attempt to determine the relationship between body height and weight. These are the body surface area (BSA) and body surface index (BSI). Generally, these body parameters are described as clinical health indicators that described how healthy an individual body response to the other internal organs. The aim of the study is to discuss the use of BSI as a better clinical health indicator for preclinical assessment of body-organ/tissue relationship. Hence organ health condition as against other body composition. In addition the study is `also to determine the best body parameter the best predict other parameters for clinical application. The model parameters are presented as; modeled height and weight; modelled BSI and BSA, BSI and BMI and modeled BSA and BMI. The models are presented as clinical application software for comfortable working process and designed as GUI and CAD for use in clinical application.

Enterprise Risk Management (ERM) is an effective technique in managing risk within an organization strategically and holistically. Risk culture relates to the general awareness, attitudes and behaviours towards risk management in an organisation. This paper presents a conceptual model that shows the relationship between risk culture and ERM implementation. The dependent variable is ERM implementation, which is measured by the four processes namely risk identification and risk assessment; risk treatment; monitor and consult; communicate and consult. The independent variables under risk culture are risk policy and risk appetite; key risk indicators; accountability; incentives; risk language and internal relationships. This study aims to empirically test the relationship between risk culture and ERM implementation among Malaysian construction public listed companies. Risk culture is expected to have direct effects and significantly influence ERM. This study contributes to enhance the body of knowledge in ERM especially in understanding significant of risk culture that influence its’ implementation from Malaysian perspective.

This study intends to find out the mediating effect of organisational culture on the relationship between information system and sustainable performance of manufacturing sector in UAE. This study used AMOS-SEM software to develop mediation model that linking the mediating relationships between Information System, Organisational Culture and Sustainable operation Performance. Data was collected through questionnaire survey among the operation staff of Abu Dhabi manufacturing companies. A total 250 questionnaires were distributed however 205 were returned and only 200 are valid which indicates a response rate of 80%. The analysis found that TPS has positive but not significant effect to SP; OIS has positive but not significant effect to SP; FMW has a positive and significant effect on SP; SDS has a negative and not significant effect to SP and SP has positive but not significant effect OC. For the path relationship between the four exogenous variables (TPS, OIS, SDS, and FMW) and the mediator variable (OC), the results are TPS has positive and significant effect to OC; OIS has positive but not significant effect to OC; FMW has positive and significant effect to OC and SDS has positive and not significant effect to OC. Collectively, the five exogenous constructs (TPS, OIS, SDS, FMW and OC) explained 89% variation in operational performance and 86% of the variation in organisational culture. However, for a mediator, it was found that OC has no significant mediating effect on the relationship between TPS and SP; OC has no significant mediating effect on the relationship between OIS and SP; OC has no significant mediating effect on the relationship between SDS and SP and OC has no significant mediating effect on the relationship between FMW and SP. it can be concluded that there is a positive relationship between information system dimensions and operational performance. However organizational culture has no contributing any mediating effect to the relationship. These findings have contributed to the body of knowledge and could be shared among the UAE manufacturing practitioners.

The relevance of the article is determined by the existence of contradictions between the need to introduce innovative technologies into the educational process at school, as an integral attribute of modern education, and the negative influence of factors on the physical and psycho-emotional state of health of students related to the use of information and communication tools (computers, phones, headphones). The goal of the study was to assess the relationship between the timing of the use of information and communication tools and the frequency of functional and psycho-emotional complaints in groups of middle and high school schoolchildren. 400 schoolchildren of the Saratov Region, the Moscow Region, Leningrad Region and the Republic of Dagestan were surveyed, who made up two groups of research: middle-school schoolchildren (grades 5–6) and high-school schoolchildren (grades 10–11 The survey was carried out by means of the standardized formalized cards which included the questions considering usage time of computers and mobile phones, complaints to a headache, hands pain, other pain and/or feeling of discomfort from visual organ and the organs of hearing, as well as a psycho-emotional state. Statistical analysis of the data was performed using the STATISTICA application software program by StatSoft Inc (USA). To compare the frequencies of a binary feature, a fourfold table of absolute frequencies was constructed and the level of statistical significance for the exact Fisher’s two-tailed test criterion was determined. The study was conducted according to the requirements of bioethics, after signing informed consent statement by teenagers and their parents. The study examined the relationship between the timing of the use of information and communication tools and the frequency of complaints in groups of schoolchildren. The results of the study should be taken into account when developing and implementing preventive measures to prevent negative effects of computers and mobile devices on the body of students.

Nanoparticles Toxicity

We conducted a comparative assessment of the nickel oxide nanoparticles toxicity (NiO) of two sizes (11 and 25 nm) according to a number of indicators of the body state after repeated intraperitoneal injections of these particles suspensions. At equal mass doses, NiO nanoparticles have been found to cause various manifestations of systemic subchronic toxicity with a particularly pronounced effect on liver, kidney function, the body’s antioxidant system, lipid metabolism, white and red blood, redox metabolism, spleen damage, and some disorders of nervous activity allegedly related to the possibility of nickel penetration into the brain from the blood. The relationship between the diameter and toxicity of particles is ambiguous, which may be due to differences in toxicokinetics, which is controlled by both physiological mechanisms and direct penetration of nanoparticles through biological barriers and, finally, unequal solubility.

The Relationship

Posture is commonly perceived as the relationship between the segments of the human body upright. Certain parts of the body such as the cephalic extremity, neck, torso, upper and lower limbs are involved in the final posture of the body. Musculoskeletal instabilities and reduced postural control lead to the installation of nonstructural posture deviations in all 3 anatomical planes. When we talk about the sagittal plane, it was concluded that there are 4 main types of posture deviation: hyperlordotic posture, kyphotic posture, rectitude and "sway-back" posture.Pilates method has become in the last decade a much more popular formof exercise used in rehabilitation. The Pilates method is frequently prescribed to people with low back pain due to their orientation on the stabilizing muscles of the pelvis. Pilates exercise is thus theorized to help reactivate the muscles and, by doingso, increases lumbar support, reduces pain, and improves body alignment.

Purpose. Increasing the uniformity of distribution of mineral fertilizers and other bulk materials due to the stability of their feed from the body to the spreading working bodies using the top feeder. Methods. The following methods are used to achieve this aim: the method of comparing the differences between individual groups of fertilizers, the method of analyzing the properties of a new technical system, the method of functional inventiveness, and the methods of theoretical and analytical mechanics. Results. The traction body of the conveyor of the upper feed of the body fat body machine for mineral fertilizers and other bulk materials was substantiated and the relationship between the height of its scrapers and the distance between them was established, as well as the nature of the mineral fertilizer pressure on the curvilinear wall of the body. In addition, the design of the advanced body fertilizer spreader is justified, which ensures a stable flow of fertilizers from the body due to the improvement of the top feeder. Conclusions. Because of the conducted researches, the advantages of machines equipped with top feeder are found. They create the conditions for the forced feeding mineral fertilizers and other loose materials from the container to the distribution bodies, which is a prerequisite for their evenness on the surface. With this, the imperfection of known machines with the top feeder constrains their introduction into agricultural production. On this account, a more thoroughly constructed solution of the body feeder of the top feed is substantiated, in which the conveyor provides a stable supply of fertilizers from the body with reduced energy consumption during operation. Keywords: analysis, feed, upper device, conveyor, stability, fertilizers, flow ability, body.
