Authors: Valovoi Olexander I. , Eremenko Olexander Yu. , Valovoi Maksym O. , Volkov Serhii O.
Published: September 2020

The sustainable development of industry and society requires new approaches to the building structures design. The article presents the indices of strength, crack resistance and width of crack opening obtained as a result of experimental testing of beams with hybrid reinforcement with basalt plastic and metal armature. The following beams were examined for comparison purposes: the ferroconcrete beams of the control-series, and the twin beams reinforced only with basalt-plastic reinforcement. It was found that the replacement of the metal armature with basalt plastics led to an increase in strength, on average, by 40%. Similar strength indices were obtained for hybrid reinforcement beams. Crack resistance indices of hybrid reinforcement beams were found to be close to ferroconcrete beams of the control series. Crack resistance indices for these beams were also by 84... 89% higher in comparison with beams reinforced with basalt-plastics. The width of crack openings in hybrid reinforced beams did not exceed the maximum permissible norms at the operational level of loads (70% of destructive) and were smaller than in beams reinforced with basalt plastic reinforcement. Hybrid reinforcement efficiency has been established to improve the performance criteria of beams reinforced with composite armature.

Authors: Kryvenko Pavlo V. , Kovalchuk Oleksandr Yuriyovich
Published: September 2020

The paper discloses results of durability studies of alkali activated concretes based on different alkali sources using aggregates capable to alkali-silica reaction (ASR). Active aggregates are representing by perlite, andesite, basalt and sandstone. It is shown that the alkali-reactive aggregates, in degree of their influence on expansion deformations occurring in the slag alkaline concretes may be placed in the following row: perlite< sand< sandstone< basalt< andesite, and a growth of expansion deformations is observed with increase in the active silica content in the aggregate. Also it is set that alkaline components, in degree of their influence on the rate of expansion deformations development in the slag alkaline concretes made with reactive aggregates, may be placed in the following sequence: Na2CO3<Na2O SiO2 < NaOH< Na2O 2SiO2.

Published: September 2020

Crystallographic characteristics of nanodispersed materials obtained by plasma-chemical synthesis were studied. Using industrial equipment for plasma-chemical synthesis the nanodispersed powders of high-melting carbide, nitride, carbonitride and silicide class compounds based on titanium, magnesium, aluminium, silicon were obtained. Technology for synthesis of powder fraction less than 100 nm was developed. The efficiency of nanodisperce compositions use in smelting of structural steels was determined. In the result of 10Г2С steel modification with Ti (CN) nanopowder strength, plastic properties and impact toughness were improved. Elemental composition of nanodispersed composition was determined: SiC, TiC, TiN, Ti (CN), AlN, Mg2Si, Mg3N2. The elemental composition of synthesized compounds corresponded to stoichiometric composition. Microdiffractional patterns of the particles were analysed, it was shown that nanopowders belong to the solid crystalline bodies with metallic bond. It has been found, that titanium carbonitride Ti (CN) particles have face-centered and silicon carbide (SiC) particles have hexagonal crystal lattice. Experiments for steel 10Г2 and 10Г2С modifying with nanopowder compositions on base of Ti (CN) and SiC were carried out. The efficiency of nanodisperce compositions use in smelting of structural steels was determined. In the result of 10Г2С steel modification with Ti (CN) nanopowder strength, plastic properties and impact toughness were improved. The choice of nanodisperce titanium carbonitride Ti (CN) powders with 100 nm fraction for light alloy steels modifying was justified. The required criteria for choice of nanopowder modifiers were obtained: insolubility in smelt, correspondence of crystal lattice to steel matrix, commensurability with austenite germ critical radius in crystallizing.

Published: September 2020

The article shows the prospects of using large-sized ceramic stones for modern housing construction. A review of the raw materials and technologies for their production is given. It is emphasized that the most promising technology for the large-sized ceramic stones’ production is a hard extrusion technology with the possibility of laying raw products on firing buggies and accelerated drying and firing modes. The characteristic of waste piles processing screenings in East Donbass, which are considered to be the by-products of coal mining, as the main raw material for the large-sized ceramic stones’ production is given. Their ceramic properties and results of the raw materials’ selection are given, including: screenings - 60-65%; siliceous clay - 20-30% coal sludge - 10-15%, on the basis of which it is possible to obtain the products with low cost and high strength for the load-bearing wall structures. The features of the ceramic material microstructure based on the obtained raw material mixtures with optimal porosity are noted. It is shown that the waste piles’ involvement in the process of ceramic stones production will make it possible to obtain products with a density of less than 800 kg/m3, less thermal conductivity 0,20 m·°С)/W and the brand strength M150 and above, with a minimum cost. This will create a serious competition for gas silicate products and achieve a level of ceramic stones’ use in the total volume of wall products for the housing construction of 80%, like in Western Europe.

Published: September 2020

The studies’ results to determine the gypsum, ash and Portland cement components proportions, which would ensure a decrease in the specific binder consumption, as well as the ash grain composition’s effect on the properties of the gypsum cement pozzolan composite, are presented. It was revealed that the use of volcanic ash together with Portland cement in gypsum concrete composites allows reducing gypsum consumption by up to 50% without a significant decrease in strength characteristics. At the same time, the developed gypsum concrete composites have increased water resistance. The influence of the ash particle size distribution on the strength properties of the composite is ambiguous; in the compositions with a high ash content it is advisable to use larger fractions, and with a content of less than 50% ash in the composite, - the small fractions. To study the parameters’ effect of the dispersed reinforcement with basalt fibers on the properties of a gypsum-cement composite, an experiment with such a second-order composite rotatable plan as regular hexagon was conducted. It was found that the maximum values ​​of optimization parameters are observed in the central area of ​​the plan with and . The compressive strength of a fiber gypsum cement pozzolan composite increases by 1.15-1.18 times, when bending, by 1.56-1.72 times with respect to the strength of the initial matrix.

Recently, the frame composite materials have been developed greatly at the production introduction level. The manufacturing technology of these materials is carried out in two stages: first, large aggregates are glued into the frame, and second, the porous frame voids are impregnated with the matrix component. In this article, we studied the various aggregates’ effect on the polymer concrete frame structures properties using epoxy binders. The materials based on the quenched cullet, brickbats, granite and limestone crushed stone, and the polymer granules were considered as large aggregates. The studied properties were the strength and elastic modulus. Quantitative dependences of compressive and bending strength, elastic modulus of frame composites on the aggregate type and other prescription factors are obtained. Using the methods of mathematical experimental planning, the optimal particle size distribution for the composites with grains from quenched cullet was selected. Particular attention should be paid to the possibility of using industrial wastes in polymer concrete compositions: polymer granules, quenched cullet and brickbats. Used glass makes up about 10% of the household waste. Its reuse is usually associated with high capital costs allocated for sorting glass by color, removing stones and other impurities. Glass grinding allows to get a fine-grained filler and aggregate. Strength and deformation characteristics of the matrix compositions, frameworks and composites as a whole are determined.
The Reinforced Concrete Reinforcement Corrosion Degradation Inhibition with Nitrates of Alkali and Alki-Earth Metals
Authors: Rumyantseva Varvara , Konovalova Viktoriya
Published: September 2020

In order to determine the inhibitory additives concentration influence degree on the corrosion degradation rate, we studied the anode behavior of steel reinforcement made of steel grade St3 in a 10% solution NaCl with and without the inhibitors additives of various concentrations. As inhibitory additives, nitrates of potassium, sodium, magnesium, calcium and zinc were introduced into the aggressive environment, since they are often introduced into concrete compositions to accelerate their hardening. Polarization curves have been obtained for steel reinforcement in an aggressive environment, allowing the corrosion rate calculation. It was established that the introduction of potassium and zinc nitrates in an amount of 0.5% into an aggressive environment has the greatest effect on the corrosion processes’ inhibition. When nitrates of alkali and alkali-earth metals are introduced into an aggressive environment, the change in the reinforcing bars mass made of St3 steel occurs 7-8 times slower. Increasing the concentration to 1 and 1.5% is shown to be impractical, due to the small difference in the effect on the reinforcing steel anodic dissolution. A study on the effect of combining inhibitory additives on the corrosion resistance of steel reinforcement in a 10% solution NaCl was made. It was found that the combined action of inhibitors is less effective than the single effect of additives on the corrosion rate.

Published: September 2020

A detailed theoretical analysis of the processes occurring in foam concrete mixtures in the period between their laying in the mold and the phase transition “from viscous to solid” completion moment. The stages of the formation of inter-pore septa in foam concrete mixtures, depending on the material nature and shape of the solid dispersed particles of raw materials, are sequentially considered. It is shown that their shape affects the mass transfer rate and the density of inter-pore septa during the structure formation. The reasons for the fluctuations in the elasticity of foam films during the predominance period of viscous bonds between the components of the raw material are described. The gas inclusions factors of influence on the dispersion parameters and, as a consequence, the aggregative stability of foam mixtures, are ranked. The positive dispersed reinforcement effect on the mass transfer processes in mixtures and the hardened concrete strength is substantiated.

Published: September 2020

Papillon-Lefèvre syndrome (PLS) is a rare disorder characterized by palmar plantar hyperkeratosis and rapidly progressive periodontitis with loss of deciduous and permanent dentition at an early age. It is reported to occur in 1 to 4 individuals per million people. This case report presents highlighting features of the rare PLS in a 17-year old male who complained of discomfort while mastication and it was accompanied with symmetrical, sharply demarcated erythematous plaques involving the skin of the palms and soles, which extended to the finger joints, elbows, and knees. Along with the rough and dry skin, hyperhidrosis of lesion with a foul odor and transverse grooving of nails were noted. The past dental history revealed normal eruption of deciduous teeth followed by pre-mature mobility and shedding in 4-6 months. Permanent teeth also showed normal eruption and early shedding in the next 4-5 years. Complete edentulous maxillary and mandibular arches led to a decrease in alveolar bone and facial heights. There was no similar disorder in the patient’s family but family history revealed the consanguineous marriage of the patient’s parents.

Published: September 2020

In addition to the best possible overall survival, discontinuation of the tyrosine kinase-inhibitor (TKI) treatment [treatment free remission (TFR)] without observing a recurrence of the disease has become a standard part of chronic myeloid leukemia (CML) care. Worldwide, more than 2000 patients with CML have attempted TFR, and very rare instances of disease transformation have been reported. Several studies in the last decade have demonstrated the feasibility and safety of TKI discontinuation in selected patients with CML who achieve deep and sustained molecular response with TKI. This has moved prime-time into clinical practice although open questions remain in terms of understanding the disease biology that leads to successful TKI cessation in some patients while not in others. Despite the remaining questions regarding which factors may be considered predictive for TFR, treatment interruption is a safe option provided that adequate molecular monitoring is available, with prompt re-initiation of TKIs as soon as major molecular response has been lost. Data from ongoing trials should help refine decisions as to which patients are the best candidates to attempt TKI discontinuation, frequency of a safe monitoring, optimal strategies to sustain ongoing TFR and increase the number of patients who can access to discontinuation programs.
Accuracy of Undergraduate Athletic Training Student Performance Factors for Determining Board of Certification Exam First-Time Pass Outcomes
Authors: Hobson Zachary Ryan , Miller Sayers John , Downs Danielle Symons , Vairo Giampietro Luciano
Published: September 2020

Context

There is a lack of current evidence to help athletic training programs identify students poised for first-time Board of Certification (BOC) exam success as a means to ensure compliance with contemporary accreditation standards. Various academic variables have been previously identified as predictors of first-time success; however, these investigations reflect prior versions of the credentialing examination based on what are now obsolete editions of the professional practice analysis.

Objective

To determine the accuracy of undergraduate athletic training student performance factors as indicators of successfully passing the current version of the BOC exam on a first attempt.

Design

Casual-comparative (ex–post facto) quasi-experimental.

Setting

An accredited undergraduate athletic training program.

Patients or Other Participants

A recent sample of athletic training program graduates (n = 43).

Intervention(s)

Archived data were collected from student academic records and analyzed.

Main Outcome Measure(s)

Receiver operating characteristic curve analysis computed the area under the curve (AUC), which was used to determine accuracy of variables. Optimal thresholds for passing the BOC exam on a first attempt were computed for each variable by the index of union method.

Results

The AUC and associated thresholds for factors were as follows: cumulative grade point average (GPA) upon entry to the major (AUC = 0.67, threshold = 3.20); preprofessional-phase course GPA (AUC = 0.81, threshold = 3.48); averaged admission interview score (AUC = 0.49, threshold = 8.46); averaged preceptor evaluation of applicant score (AUC = 0.53, threshold = 93.88%); unique composite score (AUC = 0.80, threshold = 7.34); cumulative GPA upon graduation (AUC = 0.68, threshold = 3.19); combined math and reading SAT score (AUC = 0.90, threshold = 960); clinical education hours (AUC = 0.61, threshold = 1131.08).

Conclusions

Preprofessional-phase course GPA provided the greatest accuracy of the secondary admissions criteria; however, the combined math and reading SAT score provided the greatest accuracy of all examined variables. Furthermore, the unique composite score may represent an accurate, all-inclusive indicator of success. Program administrators and athletic training educators may use these outcomes to shape their related programmatic operations.

Published: September 2020

This study quantitatively analyzes the risk communication contents of the human Monkey pox epidemic in 2017 as reported in selected Nigeria’s national newspapers (The Guardian, Punch, This day and Vanguard). Framing theory and Issue-attention cycle model formed the theoretical foundation of the study. Data for this study was obtained through the census method. Thus, all the daily editions of the selected newspapers within the study period were searched and reports on the monkey pox epidemic found were contentanalyzed. Findings indicate that monkey pox reports were placed in less prominent positions as straight news within the selected tabloids. Tension and controversy were key reportorial approaches to monkey pox happenstances nationwide. Reports on precautionary measures against the spread of the monkey pox virus were few. However, delayed and lethargic reports of the monkey pox epidemic were found in all the selected tabloids. This study contributes to empirical evidence on the delay in communicating health risk and the unsatisfactory reportage of infectious diseases outbreaks in Nigeria, contrary to global concerns of promoting good health and wellbeing for all. Therefore, as zoonotic diseases such as monkey pox continue to re-emerge all-around the globe, the study recommends that the news media should prioritize infectious diseases prevention as part of their risk communication advocacy to reduce vector interactions with human and nonstop daily updates during public health emergencies through the news media to increase trust in public health officials and the response efficiency.

Shadow Prices of Non-performing Loans for Chinese Banks in the Post-Crisis Era
Authors: Zhao Shirong
Published: September 2020

This paper examines how non-performing loans (NPLs) affect Chinese commercial
banks before, during, and after the 2008 global financial crisis as well as the
subsequent 2008--2010 stimulus. By accounting for NPLs as undesirable outputs,
banks' technical efficiency is estimated using directional output distance function.
The envelop theorem is applied to calculate the shadow price of NPLs. The shadow
price of NPLs is the opportunity cost of reducing NPLs by one Chinese yuan.
Empirical results show that the four major state-owned banks are the least
technically efficient while foreign banks are the most efficient over the sample
period 2007-2014. I also find that the crisis has a negative effect on banks' technical
efficiency while the stimulus initially has a positive effect on four major stateowned commercial banks and joint-stock commercial banks, but later shows a
negative effect with a higher default ratio and lower efficiency. Finally, the data
show that the stimulus has greatly increased the shadow price of NPLs for four
major state-owned commercial banks. Starting in 2011, the shadow prices of NPLs
for four major state-owned commercial banks are much higher than all other bank
types.

Pendidikan Demokrasi dalam Kurikulum Bermuatan Ideologi pada Institusi Pendidikan Islam
Authors: Samsudin Umar
Published: September 2020

Education as a major factor in the development of people's culture is often used by various thoughts and ideologies to spread their understanding and thinking patterns. It is not strange if a thought dominates a certain educational institution or system. Among the ideas that influence and even determine the goals and learning methods of an educational system are ideology and religion. The relationship between education and ideology is rooted in the history of education. The domination of an ideology is not only obtained through revolution or violence carried out by state institutions, but also through other institutions, such as religious institutions, education, mass media and the family. And it becomes clear that the nature of education is very dependent on the perspective of the ideology it adopts.

Abstrak

Pendidikan sebagai faktor utama perkembangan budaya masyarakat, seringkali dimanfaatkan oleh berbagai pemikiran dan ideologi untuk menyebarkan pemahaman dan pola pikirnya. Sudah tidak asing lagi jika suatu pemikiran mendominasi lembaga atau sistem pendidikan tertentu. Di antara pemikiran-pemikiran yang banyak memberikan pengaruh dan bahkan menentukan tujuan dan metode pembelajaran suatu sistem pendidikan adalah ideologi dan agama. Hubungan antara pendidikan dan ideologi sudah mengakar dalam perjalanan sejarah dunia pendidikan. Dominasi suatu ideologi tidak hanya didapatkan melalui revolusi atau kekerasan yang dilakukan oleh institusi-institusi negara, tetapi juga dapat melalui institusi-institusi lain, seperti institusi agama, pendidikan, media massa dan keluarga. Dan menjadi jelaslah bahwa hakikat pendidikan sangat tergantung dari kacamata ideologi yang dianutnya.
Mineral oils as the pressing problem of hygienic safety of a cardboard packing
Authors: Mikheeva A. Yu. , Zaritskaya Ekaterina V. , Iakubova I. Sh. , Alikbaeva L. A. , Deinega A. V.
Published: September 2020

Introduction. Providing sanitary and epidemiological safety for the secure packing production is a mandatory requirement for all manufacturers of food packing materials, no matter if it is in direct contact with foodstuff or not. However, hazardous chemicals can penetrate products from recycled materials, as well as from the moving parts of any packing equipment. Hence, the problem of packing material contamination by mineral oils, which can occur while using recycled materials, printing inks for making inscriptions and pictures, lubricating components of equipment, is of on-going interest. If packing materials are contaminated by mineral oils adverse chemicals can penetrate the foodstuff from the packing. Current packing safety requirements of European and Customs Unions differ in certain issues, in particular, hygienic regulation of mineral oils. Determination and assessment of mineral oil concentration are not regulated by Technical Regulation of the Customs Union 005/2011 “On Packing Safety” (TP TC 005/2011) in contrast to the requirements of European Union regulations which state allowable concentration and safe level of hydrocarbons in packing.Material and Methods. 23 samples of cardboard packing from various manufacturers were studied, 10 of them containing wastepaper, 9 containing cellulose materials, and 4 samples being produced without recycled materials. The level of mineral oil migration into the air or aquatic simulated environments was determined. The studies were carried out at the “Arbitrazh” chemical and analytical Center of the D.I. Mendeleev All-Russian Scientific Research Institute, by gas chromatography using Perkin Elmer Auto System. Supelco standard was used for getting calibration characteristics, i.e.: a mixture of normal structure aliphatic hydrocarbons from C6 to C44, mass parts of certain hydrocarbons being from 1 to 12% of the masses.Results. All studied cardboard packing samples were found to contain mineral oil in the hydrocarbon range of C7-C17. Mineral oil migration levels from 19 cardboard packing samples into simulated air and aquatic environments were determined.Conclusion. Hygienic safety regulation issues of foodstuff cardboard packing are relevant and require further research. It is reasonable to include mineral oils into the list of regulated sanitary-epidemiologic safety indices, and standard values of chemicals releasing from food-contacting packing into the list of monitored indices TP TC 005/2011.

A comprehensive hygienic assessment of the operational conditions of dentists providing care to children was performed at 49 workplaces in 5 state medical institutions in St. Petersburg. We studied the factors of the operational environment (physical, chemical, biological), as well as the factors of the labor process (severity and hardness), and performed the comparison of the operational conditions of pediatric dentists, dental surgeons, and orthodontists. The paired t-test or Mann-Whitney was used for comparison of means. All tests were two-way; the level of statistical significance p <0.05.Results. According to the microclimate parameters, vibration, and lighting, all workplaces corresponded to the second (permissible) class of working conditions. In terms of noise, the working conditions of pediatric dentists and orthodontic corresponded to class 3.3, and the working conditions of dental surgeons - to class 2. The degree of chemical pollution at all workplaces corresponded to class 2, the degree of biological air pollution - to class 3.2. According to the hardness of the labor process, the working conditions of dentists of specialties under investigation corresponded to class 2 at 36 workplaces (73%) and class 3.1 at 13 workplaces (27%). In terms of labor intensity, they corresponded to class 1 at 20 workplaces (41%) and class 2 at 29 workplaces (59%). The overall assessment of operational conditions for pediatric dentists and orthodontists corresponds to class 3.3, and for dental surgeons – to class 3.2.Conclusion. The major harmful factors at the workplace of dentists were noise, biological pollution, and the hardness of the work process. It is necessary to further study the comprehensive and combined effects of various occupational factors of dentists taking care of children to maintain health, working capacity, and high-level quality of life, as well as to develop measures for their improvement.

Introduction. The relevance of the study is determined by the tasks set in the National Project “Demography” (Federal Project “Senior Generation”), and consists in the need for registration of functional characteristics of the organism of older age groups in the accounting system of measures to preserve their health.Aim of the study is to establish the characteristics of anxiety and components of the postural balance (CPB) in elderly women with the risk of recurrent falls.Material and methods. We examined 232 women aged 55-69 years who reported that they experienced two or more falls over the past 12 months. The first age group included women whose calendar age was in the range of 55-64 years (n = 72), the second - women aged 65-69 years (n = 160). Using the self-assessment diagnostic technique by Spielberger, Ch. D., and Khanin, Yu. L. we determined the level of situational (SA) and personal (PA) anxiety. To assess the features of the CPB, a US-manufactured computerized dynamic posturography complex Smart Equitest Balance Manager was used. Sensory Organization Test (SOT) and Motor Control Test (MCT) tests were conducted. Results. When analyzing anxiety scale values, a high level of PA was revealed in both groups of women, however, the SA indices in women 55-64 years old were lower than for women 65-69 years old (p = 0.005). All this indicates that the development of recurrent falls among women older 64 years will be accompanied by mental tension and pronounced emotional responses to postural changes. According to computerized dynamic posturography testing, age-related differences in CPB have been revealed. There was a decrease in the quality of the equilibrium function by test 5 SOT and vestibular information in postural control found in women of age group 55-64, whereas for women in the age group 65-69 there was a decrease in the quality of equilibrium function by test 4 and visual information in balance control. In the latter, there was also found an increase in the time of coordinated motor response by the test of unexpected external impact on the shift of the center of gravity capable of enhancing the risks of stuttering and falls when walking fast.Conclusion. The suggested criteria for assessing the risk of falls in elderly women can be used to develop individual health programs to prevent serious consequences in such events.

Introduction. At present, Russia occupies one of the leading places in the world in ethanol consumption per capita. The actual and unsolved problem remains the diagnosis and prevention of chronic alcoholism. The definition of carbohydrate-deficient transferrin proposed by many authors has many drawbacks, in particular, a rather high cost, as well as a limited sensitivity of the index after two weeks from an episode of ethanol consumption. For this reason, it seems necessary to search for alternative biomarkers of chronic alcoholism. One of the applicants for the role of a marker of chronic alcohol intoxication is the Red blood cell Distribution Width - standard deviation (RDW-SD). The article contains the results of a study of changes in the standard deviation of the RDW-SD in the venous blood of patients with acute ethanol poisoning in cases with chronic alcohol intoxication.The aim of this work was to quantify the change in RDW-SD in patients with alcohol dependence (chronic alcohol intoxication) during periods of exacerbation (acute alcohol poisoning of moderate severity). Material and methods. The research materials were clinical blood tests of 245 patients on the first day after admission to the Department of Toxicology of the I.I. Dzanelidze. Research Institute of Emergency Medicine.Results. From the literature, it is known that the RDW-SD is largely associated with folic acid deficiency. Vitamin B9 deficiency can significantly increase the risk of cardiovascular disease due to the development of hyperhomocysteinemia in patients. Particular attention is required for patients aged 46-65 years, who have the highest level of RDW-SD with an increased risk of developing cardiovascular events. At the same time, the highest mortality rate in this age group from the reasons associated with the use of ethanol is noted, which gives reason to consider RDW-SD as one of the possible indices of the mortality risk. Conclusion. The possibility of using the magnitude of the change in the RDW-SD index as a biomarker of chronic alcohol intoxication in patients with a certain risk of cardiovascular complications is discussed with the rationale for the appointment of folic acid preparations as part of the complex treatment of chronic alcohol intoxication.
Information society: socio-hygienic aspects of the transformation of employment and working environment
Authors: Druzhilov Sergey A.
Published: September 2020

Introduction. The current historical period is characterized by significant transformations in all spheres of life activity. The reasons for the changes are the development of information technologies and globalization processes. In the information (post-industrial) society, transformations are associated with the introduction of the principles of flexibility in job placement and labor organization. The transition to flexible forms of employment appears as a risk factor for the deterioration of working conditions and the reduction of workers’ security. “Social pollution” of the production environment is spreading. These include management methods that harm the well-being of workers.The aim of the study is the evaluation of the influence of flexibilities of employment and labor relations on the deterioration of working conditions as a risk factor for the well-being of workers.Material and methods. The study object in the article is flexibility as a socio-psychological and organizational-economic phenomenon. A comparative analysis of the views of various authors and their theoretical generalization.Results. A modern understanding of the information society as a society of network structures based on innovation and decentralization, as well as employment on adaptability to market conditions is presented. The introduction of the flexibility of employment means a departure from the standard model of labor relations. The negative consequences of labor flexibility for workers are given: instability, compulsion, unsteadiness, and lack of guarantees. Employment unsteadiness occurs both in the informal and formal sectors of the economy. The statistics cited indicate a trend towards an increase in the proportion of workers included in unsustainable and precarious employment. The influence of “social pollution” of the intra-organizational environment in the form of adverse management decisions introducing instability and unreliability in working conditions is considered. Their consequence is a violation of the social and psychological well-being and somatic health of workers. Conclusion. The more employment differs from the standard, the higher its instability, and lack of guarantees for the worker, the higher the risks of deterioration of working conditions, health, and job loss. There is a connection between the instability of employment, psychological well-being, and health.

Introduction. The objective of this work was the radiation survey in the vicinity of “The 30th Shipyard” Company. The studies were carried out during the period between 2014 and 2016 within the supervision area and in the area of the radioactive trace formed after the accident of 1985 in the nuclear submarine.Material and methods. The following methods were used in the course of the survey: pedestrian gamma surveys, gamma spectrometry measurements of radionuclides using a gamma spectrometer, and radiochemical extraction of 90Sr, followed by measurement of its activity at radiometric installations.Results. Gamma ambient dose equivalent rate within the supervision area beyond the radioactive trace varies within the range between 0.09 and 0.18 µSv/h. The specific activities of 90Sr, 137Cs, and 235U in soil do not exceed 11, 34, and 5.8 Bq/kg, respectively. The specific activity of 60Co in the soil of the Dunay village is lower 0.42 Bq/kg and does not exceed 4.9 Bq/kg at the rest part of the supervision area. The area of the radioactive trace limited by 0.13 µSv/h iso-line does not exceed 0.5 km2, while that limited by 0.3 µSv/h iso-line - 0.0063 km2. Within the area of the trace, the highest value of the gamma dose rate accounts for 0.60 µSv/h. Soils contaminated with emergency radionuclides do not belong to solid radioactive waste. Emergency radionuclides migrated in soil up to 20 cm depth. Today, 137Cs is firmly fixed in the soil. 40-45% of 60Co activity is in acid-soluble form. Under specific conditions, it can migrate deep into the soil and be accessible to plants.Conclusions. Within the supervision area of “The 30th Shipyard” Company, except for the area of the radioactive contamination trace induced by the accident, the radiation situation is the same as that in the area of the Primorskiy Krai. The soil of the radioactive trace does not belong to solid radioactive waste. In the future, the improvement of the radiation situation on the trace will be mainly due to the physical decay of radionuclides.
