Assessment of Flood Risk and Mapping of Flood Risk Zones in Yenagoa, Bayelsa State, Nigeria
Authors: Oladimeji O.E. , Ohwo O.
Published: May 2022

In recent years, most Nigerian cities have experienced several major flood episodes with serious catastrophes. Hence, this study was carried out to assess and map flood risk zones in Yenagoa. The Geographic Information System (GIS) and remote sensing technologies were used in generating and analyzing data to identify the different flood risk zones in Yenagoa. Environmental indices such as flood heights, land elevation and land cover images were analyzed using geo-statistical tools such as map overlay operations to produce a flood risk map. The flood risk map produced and the ground truthing carried out confirmed that the highest flood risk are located within residential areas where about 32% of the built-up area was vulnerable to moderate or high risk of flooding. The study revealed that both natural and anthropogenic factors are responsible for the severe flooding experienced in Yenagoa, especially due to heavy precipitation, elevation of the area, poor waste disposal, and inadequate urban development control amongst other factors. The city was classified into three flood risk zones-high, moderate and low, with about 48% of the area being either at moderate or high risk of flooding. It is therefore recommended that the Ministry of Physical and Urban Development should carryout proper urban development control, which will prevent building on flood plains, wetlands and natural drainage channels.

The need to reclaim contaminated soils is important in ensuring the sustainability of life and biodiversity. Food crops grown in heavy metal contaminated soils have the risk of passing the accumulated metals to man and such has been demonstrated to cause various diseases in man. In this study, we investigated the potentials to reclaim heavy metal contaminated soil using Eudrilus euginae and Lumbricus terrestris. The contaminated soils were obtained from mechanic, welder and metallic workshops and were grouped individually and as combinations. The soils were incubated with the earthworms and the quantities of heavy metals in soil were determined before and after the growth of the earthworms. The percentage of the heavy lost from soils at the end of the study was calculated to evaluate the ability of the earthworm to enhance the remediation of heavy metal contaminated soil. The presence of the earthworms led to more reduction of the levels of the heavy metals in the soils than natural attenuation. The presence of L. terrestris led to a lower reduction of Cd, Cr and Pb in the combined soil from the three sites but a greater reduction of Zn and Ni from such soil. The presence of E. euginae led to greater loss of all the heavy metals in the soil from the welder workshop and greater loss of Cd, Pb, Ni and Zn in the soil the mechanic workshop than L. terrestris. The presence of E. euginae led to more loss of Cr, Pb, and Ni in combined soils of mechanic and welder workshops and mechanic workshop and metallic dumpsite. The findings of this study show that although the presence of both earthworms enhanced the remediation of heavy metals from the soils, the efficiency of the remediation is organism-specific and site-specific. Study on detailed mechanisms of enhancing heavy metals by earthworms is recommended.

The international dependence on non-renewable power supply including fossil fuels has led the sector toward power insecurity. This has necessitated the worldwide attempt to reduce the dependence on  fossil fuels and broaden an economically feasible and scalable alternative  fuel supply so that it will  additionally lessen huge emissions of CO2 within side the  surroundings which in flip will result in  discount environmental pollution. Biofuels have the  potentials to offer a feasible opportunity to fossil  fuels and can lessen overall CO2 emissions.  Algae appear like a rising supply of biomass for biodiesel  that has the capacity to absolutely  displace fossil fuel. Biodiesel has gain sufficient interest in latest years  because of its green  nature, non-poisonous characteristics, biodegradability and decrease net  carbon cycle as  compared to standard diesel fuel. In this research, Spirogyra sp. was collected from Tubu  river, a tributary of River Kaduna, as a source of biomass feedstock for biodiesel production.  Spirogyra  sp. turned into cultured in various nitrogen (2.94 x 103 (100%), 2.20 x 103 (75%),  1.47 x 103 (50%), 0.73 x  104 (25%), and 0.000 (0%)) concentrations in Bold’s Basal Media (BBM) in a laboratory test for 21 days at  25-28°C ambient temperature. Oil from Spirogyra  sp. become extracted in soxhlet extractor using  n-hexane as solvent and transformed into  biodiesel through transesterification reaction. The highest biomass growth, oil, lipid content and biodiesel production were observed in treatment with 75% (2.20 x 103) Spirogyra sp. has a big capability for biodiesel production.

Published: May 2022

Syria lies at the heart of the Fertile Crescent – one of the centres of diversity of staple crops such as wheat, barley, chickpea and lentil. The country has historically been rich in agrobiodiversity, including crop landraces valued for their nutritional and culinary qualities, as well as for their resilience. With their cultivation already in decline before the start of the Syrian crisis in 2011, this study was undertaken to assess the current status of crop landraces in northwest Syria, and to initiate an ex situ conservation programme. We found a significant decline in the number of landraces in cultivation, indicating a loss of locally adapted genetic diversity. Influencing factors include insufficient seed supply, competition with commercial hybrids, falling market demand and neglect by relevant government authorities. Despite not seeing conservation as their responsibility, the participating farmers were supportive of landrace conservation and willingly contributed seeds for ex situ conservation.

Published: May 2022

Reducing the use of chemicals in vegetable cultivation is an environmentally friendly cultivation technology that is expected to reduce negative impacts on the environment. One of the efforts to reduce chemicals in cultivation is to use bacteria that live in plant roots as plant growth promoters or biopesticides. This study aims to determine the number of endophytic bacteria from bamboo and leguminosae roots that have the potential as plant growth promoting agents. The making of plant growth-promoting rhizobacteria (PGPR) starter which was carried out in this study used the roots of bamboo, lemongrass and Mimosa Pudica Linn. Furthermore, it is applied to vegetable cultivation (Chinese cabbage, tomato, carrot and green mustard/caisim) to determine the physical characteristics of vegetables from the result of PGPR application compared to results from conventional farmers. This study used a factorial randomized block design with 2 factors. The first factor is the plant roots used, while the second factor is the length of the plant roots soaking in water, namely 72, 96, 120 hours. The data from the PGPR starter analysis results are made into a table, then a descriptive discussion is carried out. For vegetable data from the cultivation results using PGPR compared to vegetable from conventional farmer results. Based on laboratory analysis, obtained the total microbes in samples from bamboo roots with a soaking time of 72 hours were higher than the other samples, namely 8.49 x 106 cfu ml-1; pH in samples of PGPR from the roots of Mimosa Pudica Linn, bamboo, lemongrass, commercial PGPR (from Central Java farmers) ranged from 3.0 to 6.7; while the total dissolved solids content ranged from 0.2 to 2.6%. Based on the graph of plant growth in the PGPR treatment and with no treatment, there is a slight difference, not much increase or decrease. In tomatoes with PGPR treatment, plant growth was higher than without the use of PGPR, while for Chinese cabbage and caisim the growth was almost the same between PGPR treatment and without PGPR. For carrots, it was seen that with PGPR treatment, plant growth was lower than without PGPR. The results of the analysis of texture, brightness level and total dissolved solids in Chinese cabbage, caisim, tomatoes and carrots with PGPR application, the characteristics are almost the same as the results of conventional farmers. By looking at these results, it is hoped that in the future cultivation innovation by utilizing bacteria around the roots, is one of the environmentally friendly cultivation applications and begins to reduce the use of chemicals in cultivation.

The study area is heavily affected by landslides with increasing frequency and intensity, causing serious damages and affecting the sustainable socio-economic development of the region. The use of mathematical methods in landslide research is increasingly interested due to the quantitative nature of parameters and calculation results. This study aims to apply the Certainty Factor (CF) and Bayesian statistics models for geological hazard evaluation. Landslide distribution is identified from remote sensing images and field surveys. Landslide inventory maps (428 landslides) were compiled by reference to historical reports, Google Earth, and field mapping. All landslides were randomly separated into two data sets: 70% were used to establish the models (training data sets) and the rest for validation (validation data sets). Fifteen environmental factors from geology, topography and hydrological information of the studied area were extracted from the spatial database. Results show that the group of factors of slope angle, Terrain Ruggedness Index, fault/lineament density, stratigraphy, geoengineering characteristics, weathering types, and maximum daily rainfall play the most important role in the formation of landslides in the study area. Validation from Certainty Factor (CF) and Bayesian statistics models show 87% and 92% prediction accuracy between hazard maps and existing landslide locations. These models show reasonably accurate landslide predictions in the study area and can be served as the basis of landslide risk-management studies in the future.

Competitiveness plays an important role in the efficiency and productivity of the Economic zone. The research analyzed the current state of competitiveness of Nghi Son economic zone, Thanh Hoa province, by means of analysis, synthesis, statistics and comparison based on the data source of Nghi Son economic zone management board. After screening and processing, the following results are obtained: (i) Competition at the enterprise level: foreign-invested enterprises act in a small number of projects but account for 73.68 of total investment capital. The number of assembly, processing and processing projects in the economic zone accounts for a large proportion, of which petrochemical and chemical industry projects take two-thirds of the registered capital, lack of the presence of other industries; (ii) Competition at the local level: Infrastructure investment projects are mobilized from central capital and socialized to build relatively synchronous and complete hard and soft infrastructure; living environment and investment support services to meet practical needs. (iii); Availability factors in the economic zone: the favorable geographical location and abundant natural resources are the factors that create the competitiveness of the economic zone. However, the problem of Nghi Son Economic Zone is that there are still some limitations that need to be overcome to improve competitiveness in the coming time.

Root and butt rots caused by Heterobasidion spp. are destructive diseases of conifer forest stands that may be controlled by spraying freshly cut stumps with chemical or biological treatments, including the effective and widely used biological control agent Phlebiopsis gigantea. In this study, we tested in vitro different Latvian isolates of the fungal species Bjerkandera adusta and Sistotrema brinkmannii for their antagonistic activity against both Heterobasidion species present in Northern Europe and Baltic countries, namely H. annosum and H. parviporum, using Latvian isolates of P. gigantea and the Rotstop® strain as controls. The growth rate of isolates on agar media and their ability to produce oidia or conidia were also assessed. In general, B. adusta performed better than S. brinkmannii. Some isolates of B. adusta ranked similarly to those of P. gigantea in terms of oidia production, growth rate and ability to overgrow the mycelium of both H. annosum and H. parviporum. These isolates will be further tested in field conditions. Key words: biological control, antagonistic fungi, fungal isolates

Authors: Manisha Sanjay Bang
Published: May 2022

The Vrana (ulcer) is considered the core subject of Shalya tantra. Vata, Pitta and Kapha are aggravated by their respective causative factors that get lodged in the exterior of the body to give rise to Nija vrana (endogenous ulcer). Nija vrana are frequently encountered problem in present era produced commonly by the morbid Doshas of the body. In the present study, Haridradi taila (ointment) is selected which is mentioned by Acharya Sushruta in the context of Vrana. It contains Kasis, Kutaki, Jati, Haridra, Tagar, Agaru, Daruharidra, Deodaru, Priyangu and Lodhra. These ten ingredients possess the properties of both Shodhan and Ropan (cleaning and healing). It was used topically in the type of chronic wounds daily one time for 30 days or till the healing of the wound, whichever is earlier. It is a single-blind clinical study where 20 patients were selected and divided into two groups 10 patients each. Experimental group patients wounds were treated with a dressing having Haridradi ointment and control group patients' wounds were treated with Framycetin ointment and dry gauze bandaging. It reduces pain, burning sensation, itching, decreases discharge, oedema and helps in gradual improvement in floor and granulation tissues as compared to control group. Nija vrana (chronic wounds) management with Ayurvedic remedies is one of the major areas of research, hence it can be speculated that Haridradi ointment possesses sufficient efficacy in Vrana shodhan and Vrana ropan (cleaning and healing of the wound) without creating any adverse effect
Ormanlara, Sıcaklara ve Yangınlara Dair: 2021 Köyceğiz Orman Yangınlarının Sosyolojik İzdüşümleri

Published: May 2022

Bu makale 2021 yazında Muğla’nın Köyceğiz ilçesinde çıkan orman yangınlarının sosyolojik olarak değerlendirilmesi hakkındadır. Makaleye kaynaklık eden veri, yangının söndürülmesinin hemen ardından niteliksel yöntemle yapılmış bir alan araştırmasına dayanmaktadır. Alan araştırması, Sandras Dağı’nda bulunan ve yangından etkilenen Köyceğiz’e bağlı köylere odaklanmıştır. Araştırmanın sonuçlarını tartışan bu makale kuramsal olarak, ormana toplumsal bir aktör olarak bakabilmeyi mümkün kılan Bruno Latour’un ve Donna Haraway’in perspektiflerinden beslenmektedir. Makalede, önce yangın, yangın alanında yapılan işler, yangından etkilenenler, ağaçların, insanların ve hayvanların durumu, medyanın yangını ele alma biçimi tartışılmaktadır. Ardından yapılan alan araştırmasının sonuçlarına başvurularak yangının arka planına ilişkin üç konu ele alınmaktadır. Bunlar birincisi, bölgede yazın çok sıcak geçmiş olmasıdır. Bu yüzden 2021 Köyceğiz orman yangınları, küresel iklim krizi sonucunda çıkan günümüz orman yangınları silsilesinin bir parçasıdır. İkincisi, orman ve insan arasındaki ilişkiler dönüşmektedir. Özellikle orman köylülerinin yaşam biçimi değişmektedir, keçi sürüleri azalmaktadır, kırsal yoksulluk arttıkça köylüler işçileşmektedir. Bu dönüşüm, ormanın bakımının aksamasına neden olduğu için yeni yangınların çıkması ihtimalini arttırmaktadır. Son olarak, neoliberal politikalarla biçimlenen bir işletme olarak orman düşüncesi, ormandan kar elde etme hırsı, ormandan yeni yerleşim alanları açılması, saldırgan madencilik gibi ilişkiler aracılığıyla ormansızlaşmaya neden olmaktadır. Bu durum yangının etkilerini ekososyal bir kriz olarak derinleştirmektedir.

Published: May 2022

Hemophagocytic lymphohistiocytosis is a rare hematologic disorder caused by dysregulated immune activation and carries a high rate of mortality. It is categorized broadly into Primary (Familial ) and secondary types. The recent classification of histiocytoses by Histiocytic society has placed Hemophagocytic lymphohistiocytosis in the “H” group. Greater awareness of Familial hemophagocytic lymphohistiocytosis is required among clinicians and pathologists for early diagnosis and a better survival. Here we report a case of Familial hemophagocytic lymphohistiocytosis correlating with clinical history, family history, bone marrow findings and genetic tests.
Democratization in Turkey under AKP Government
Authors:   Ph.D. scholar, Centre for West Asian Studies, School of International Studies, Jawaharlal Nehru University, New Delhi, Chaurasia Pavan
Published: May 2022

The term “freedom of expression” is quite broad and holistic. It includes, within its ambit, not only the conventional freedom of speech and freedom of media, but also the freedom of thoughts, cultural expression, conscience, and intellectual inquiry. Freedom of expression ensures an individual's right to express his/her views openly within the domain of constitution, which also contains the right to be criticial of the prevailing injustices, illegal, anti-social activities, and incompetence and failure of ¬¬¬the government. All this is with a guarantee of safety and without any apprehension or fear of retaliation. Freedom of expression, in contemporary times, also embraces the right to be informed and seek information by the public, to express opinions, and advocate amendments, including changing the regime without resorting to violent means through peaceful measures available in the public domain, with reasonable restrictions. In the past decade and half, Turkish experience as a transitional democracy presents an interesting case study to explain as to how the state of freedom of expression is causally related to the failure of the EU-driven reform process undertaken by the ruling AKP (Turkish: Adaletve Kalkınma Partisi) since the year 2002, when the party won the Parliamentary elections in Turkey for the first time. The issue about the press freedom and freedom of expression in Turkey has for very long time, attracted a great amount of scholarly attention and provoked extensive debate both inside and outside Turkey. Although Turkey remains one of the rare democracy in the West Asia, a region with strong monarchic and semi-monarchic tradition of government, a series of development in the past years has raised several interrogations about the qualitative and quantitative aspects of democracy in Turkey under the AKP.
The Use of Prophylactic Antibiotics as a Prevention of Surgical Site Infection for Patients with Open Fracture: A Scoping Review
Authors:   Researcher Scholar, Master of Hospital Administration, Muhammadiyah University of Yogyakarta, Prabowo Agam Meureza
Published: May 2022

Background: Fracture is a serious injury condition characterized by structural discontinuity of the bone that occurs in the form of cracks to complete, and bone fragments are not in their proper position. The incidence of open fractures is 30.7 out of 100,000 people per year. Based on the relationship with the outside world, fractures are divided into two, if the skin is still intact after breaking, it is called a closed fracture, and if there is a wound, it is called an open fracture. An open fracture is an emergency condition that can be life-threatening if not treated adequately. This is due to the relationship of fracture fragments with the outside world, which allows contamination to occur. Complications resulting from contamination are the occurrence of infection. The event of infection can cause a worsening of the patient's clinical condition. Thus, the socio-economic burden of the sufferer will increase. Therefore, prompt and appropriate treatment is needed, one of which is prophylactic antibiotics. Objectives: This scoping review aims to analyze the effectiveness of prophylactic antibiotics in cases of open fractures for the prevention of surgical site infection. Methods: Article searches were conducted using two online databases, PubMed and Scopus. The articles searched were published between 2017-2021, with the main keywords used being prophylactic antibiotics, surgical site infections, and open fracture. Results: Four articles were selected from the article search process. Based on the article review results, it is known that Staphylococcus aureus is the most common microorganism causing surgical site infection. The use of prophylactic antibiotics should be given as soon as possible after an open fracture. The most used prophylactic antibiotics are cephalosporins. The duration of use of prophylactic antibiotics is still not according to existing recommendations. Conclusion: The incidence of surgical site infection can affect healing time, length of hospitalization, repeated procedures, and increased costs. In open fractures of GA type I and II, it is recommended to use prophylactic antibiotics of first or second-generation cephalosporin. For open fractures of GA type III, it is recommended that third-generation cephalosporin be used with an aminoglycoside as prophylactic antibiotics. The duration of prophylactic antibiotics is 24-72 hours. Further research is needed to determine the most effective prophylactic antibiotics and the optimal period to prevent surgical site infections and bacterial resistance.

Our case highlights this syndrome as a rare cause of myocardial infarction in young adults.
Ventricular Septal Rupture Complicating Acute Myocardial Infarction: A Preventable Complication? Case Report and Review of the Literature
Authors:   3 Department of Cardiology, Hôpital Militaire d’Instruction Mohamed V, Mohamed V University of Rabat, Morocco, Nadhil Zayna
Published: May 2022

Despite the significant reduction in mortality from acute myocardial infarction in recent decades due to adequate medical management, cardiac monitoring, and early reperfusion, the mortality rate from ventricular septal rupture remains considerable. The risk factors for this complication have been the subject of several studies such as hypertension, advanced age, female gender, absence of angina pectoris, and anterior location of the ischemia. Surgical repair techniques have evolved over time, but the prognosis remains very poor with a mortality rate unchanged since 1990. This is why it is very important to know the clinical manifestations to specify the diagnosis by echocardiography and to allow urgent medical and surgical management. We will illustrate this fatal complication of myocardial infarction and review the different factors that predict its development through a clinical case and a review of the literature.

Published: May 2022

Introduction. This work is devoted to the study of the effect of peroxide anion radicals in submicromol concentrations and the structural organization of the associated water phase in drinking waters, activated by physical methods on the viability of a number of microorganisms in the human gastrointestinal tract. Materials and methods. Studies were carried out using standard methods of microbiological analysis of drinking water on microorganisms of Escherichia coli 1257, Pseudomonas aeruginosa, Salmonella enteritidis 5765, Enterococcus faecalis ATCC 29212, Klebsiela pneumoniae subsp. pneumoniae ATCC 700603, Citrobacter freundii 101/57. Evaluation of changes in the physical parameters of water before and after treatment with the studied technologies was carried out using electrophysical and physical-chemical parameters (hydrogen index, redox potential, content of peroxide anion radical); structural and energy indicators (by the share of the associated water phase and the density of its distribution by energy levels). Results. The data obtained indicate the strongest stabilizing effect on the viability of microorganisms implementing ATP-phase energy metabolism to be µexerted by associates of peroxide anion radicals controlling metabolic processes and providing an extra-substrate channel for maintaining the energy function of microorganisms. We assume that catalytically active waters have a systemic regulatory effect, ensuring the maintenance of homeostasis of microorganisms. Similar regulation is also possible in the intestinal microbiota of the body to maintain or suppress the activity of competing microorganisms when a person uses biocatalytically active (in the range of concentrations of peroxide anion radicals in drinking water from 0.1 to 40 drinking water µg/L) drinking water. We assume that this will solve a number of issues related to the etiology and pathophysiology of a number of gastroenterological diseases caused by changes in the electrophysical state of the internal environment of the gastrointestinal tract, promoting the emergence and development of a competing, adapted to an environment with low electron-donor capacity, bacterial microbiota. Limitations. The data obtained as a result of the experiment on biota similar to the human intestinal microbiota are of scientific interest and research involving warm-blooded animals is necessary to continue work in this direction. Conclusion. Physically treated waters affect the growth or inhibition of intestinal biota colonies, which may be associated with the controlling role of peroxide anion radicals on intracellular metabolic processes in microorganisms
Features of professional personality deformation of internal affairs bodies, penitentiary service and bailiffs
Authors: Korneeva Yana A. , Zelyanina Anna N. , Martirosova Natalia V.
Published: May 2022

Introduction. The professional activity of people who have chosen the path of serving the state, as a rule, carried out in conditions of intense psychological and physical stress, is associated with the risk of the life and health of employees. The extreme nature of everyday life is reflected in the psychological and physiological well-being of employees and explains the fairly widespread occurrence of phenomena that, to varying degrees, hinder the successful performance of professional duties, which have a real impact on negative personality changes, which include the professional personal deformation of an employee. The presented study included employees of law enforcement agencies (Internal Affairs Bodies, Federal Penitentiary Service, Bailiffs Service). Materials and methods. The total sample size was one hundred thirteen males and females. The main purpose of the study was to identify, describe and compare the features of the professional personal deformation types of employees of the Internal Affairs Directorate, the Federal Penitentiary Service, and the Bailiffs Service. The author’s questionnaire was used to study the types of professional deformation, the professional activity characteristics and a subjective assessment of the work effectiveness of law enforcement officers. Results. To describe the personal characteristics and determine the character accentuations of the surveyed, the questionnaire of G. Shmishek and K. Leonhard was used. Regularities and significant differences in the development of professional personal deformation in the studied groups were revealed. The predominant types of professional personal deformation for employees of the Internal Affairs Directorate, the Federal Penitentiary Service and the Bailiffs Service are authoritarianism, super-control and conservatism. At the same time, overcontrol is expressed above the average and has higher values in representatives of Internal Affairs Bodies and Bailiffs Service. Learned helplessness, on the other hand, is more pronounced among Federal Penitentiary Service employees. Limitations. This study included one hundred thirteen law enforcement officers (the Internal Affairs Directorate, the Federal Penitentiary Service, and the Bailiffs Service), which suggests the possibility of expanding the sample size and including representatives of other departmental structures to clarify the patterns obtained about the severity of professional deformation types, their relationship with professional efficiency and their individual-personal markers. Conclusion. The results and conclusions obtained make it possible to expand the possibilities of the methodology of psychological diagnostics of negative changes associated with a person’s professional activity, in particular, the definition of psychological tools that allow determining the severity of professional deformations.

Introduction. Burnout syndrome (BOS) is interpreted as career crisis. However, BOS is no classified as occupational or workplace-related illness, it is considered as phenomenon in the occupational context only. Aim - to assess the influence of professional activity of university teachers on the development of BOS. Materials and methods. Female teachers of three age groups (under 30 years, 30-49 years, and older 49 years) working at the North Kazakhstan University (NKU). This study employed questionnaire, physiological and statistical methods. Results. The most pronounced phase experienced by teachers is “Resistance” phase, followed by “Exhaustion” phase and then “Tension” phase. As for the age range, respondents of the first age group (under 30 years old) have expressed reaction of: “Tension” phase - 21.7%, “Resistance” - 34.7%, “Exhaustion” - 30.4%. “Resistance” response prevailed in two other age groups. A post-symptom analysis of the formed BOS phase showed the prevalence of the following symptoms in the “Resistance” phase: “R1. Inadequate emotional response”, “R4. Reduction of professional duties”, “R2. Emotional and moral disorientation” and “R3. Expansion of emotion saving. “T1.Experiencing traumatic events” symptom dominated in the “Tension” phase, followed by the symptoms of the “Exhaustion” phase - “E1. Emotional deficiency”, “E2. Emotional detachment” and “E3. Personal detachment (depersonalization)”. The dynamics of psychophysiological indicators based on the phases of the formation of BOS showed results similar to obtained from correlation analysis and analysis of variance. A post-symptom analysis of the formed BOS phase showed that the prevailing symptoms negatively affect the professional qualities of teachers. Teachers can be assumed to face increasing traumatic factors of professional activity, they cease to feel the difference between the emotion saving and inappropriate emotional response and, therefore, they try to minimize the responsibilities requiring emotional costs. Limitations. This study is limited to a selection of female teachers of the NKU, who develop BOS during their teaching activities, diagnosed according to the questionnaire of V.V. Boyko. Conclusion. It can be assumed that teachers’ professional activity causes the growth of BOS and can be classified as workplace illness, which entails the inability of an employee to perform his/her duties at a professional level.

Introduction. The article presents a non-combined observational cross-sectional retrospective study, which studied the functions of respiration of 3 categories of workers (sinkers, woodworkers, underground miners) depending on working conditions. Materials and methods. Analyzed depersonalized data from outpatient records of periodic medical examinations of underground workers from 2013 to 2017. The article presents only the analysis of spirograms. The study of respiratory function was carried out using an expert class spirometer SpiroLab III (MIR, Italy). The results were assessed by a doctor of functional diagnostics. Production factors were studied according to the results of a special assessment of working conditions carried out in oil mines according to the methodology for conducting a special assessment of working conditions, approved by order of the Ministry of Labour of Russia No. 33n dated January 24, 2014. Statistical methods were used to analyze the material: methods of parametric statistics (mean (M), standard deviation, error of the mean (m), Student’s test), the data are presented in the format M ± m, the differences were considered significant at p < 0.05. Results. An analysis of occupational morbidity among oil miners has been carried out, risk groups have been identified by profession, length of service and age. It was revealed that after 4-5 years of work in the profession, there is a tendency to impairment of the function of external respiration according to the obstructive type (decrease in forced expiratory volume in the first second (FEV1), formed vital capacity of the lungs (FVC), peak expiratory flow rate (PEF) , Tiffno index). This is suggested to be due to a combination of factors of the production environment such as oil hydrocarbons and the severity of labour. The analysis of working conditions made it possible to determine the list of harmful production factors affecting the development and occurrence of occupational diseases by workers involved in thermal mining of high-viscosity oil. Limitations. The smoking factor in the work is considered as a qualitative one, it is probably more logical to consider it as a quantitative one - smoking experience (number of years), then a connection with changes in the functions of external respiration may be revealed. Conclusion. After 4-5 years of work, oil miners show a tendency to obstructive disorders of the respiration function. The genesis of the identified changes requires further clarification.

Introduction. The emergence of various digital educational resources for children dictates the need for scientific justification of their safe use in educational and leisure activities of preschoolers of different ages. The aim of the study is the hygienic assessment of electronic educational content (EEC) of the digital educational system “Mobile e-education - Kindergarten” (DES “MEE Kindergarten”) for preschool children. Materials and methods. A hygienic observational and expert-analytical study was conducted to evaluate the EEC of the DES “MEE Kindergarten” (60 scenarios of classes) for preschoolers of different age groups. Results. To assess EEC there have been established hygienic significant indicators follows: the number, size, contrast and color scheme of information objects; the presence of text and indicators of its font design; sound and video clips; a set of navigation tools, the ability to customize the image. The analysis of the scenarios of classes showed the main indicators of EEC generally to meet the age capabilities of preschool children and the principles of hygienic safety. The results of the expert-analytical study allow concluding the electronic materials of the DES “MEE Kindergarten” can be used in the educational and leisure activities of preschool children. Limitations. The study was limited to the study of the main components of the EEC (illustrative material, audio and video fragments in the practical absence of text material), taking into account indicators important for the safe visual work of preschoolers Conclusion. The scientific substantiation of the safe using the DES “MEE Kindergarten” in the educational and leisure activities of preschoolers is given. The results of the research made it possible to identify hygienically significant indicators for assessing the EEC for preschoolers, including parameters characterizing its design; to develop hygienic recommendations for the use of the DES “MEE Kindergarten” according to the age of children and hygiene regulations. The data obtained are one of the stages in the development of a methodology for assessing and hygienic rationing of quantitative and qualitative indicators of EEC for preschoolers, preparation of hygienic recommendations for its design in the context of digital transformation of education.

Introduction. In large cities an assessment of the impact of environmental risk factors in addition to the levels of air pollution on the morbidity of the population and the medical and demographic situation should take into account the influence of the socio-economic living conditions of the population, both availability and quality of medical care. The purpose of the work is to conduct a comparative analysis, assess the informativeness of indicators of air quality, socio-economic living conditions of the population, the availability of medical care, and identify the priority of these factors in large industrial cities of different regions of Russia. Materials and methods. A comparative analysis of indicators of the ecological situation, socio-economic conditions of living and the availability of medical care to the population in large industrial cities for the period 2008-2018 was carried out according to official statistics. Results. The criterion for choosing cities for the analysis was the population size. Large industrial cities of four Federal districts were selected as objects of research: Central (Central Federal District), Volga (Volga Federal District), Ural (Ural Federal District) and Siberian (Siberian Federal District). The main source of anthropogenic load in the Central Federal District in 50.0% of cities included in the analysis is motor transport, in 25.0% - stationary, in 25.0% the contributions of sources are comparable; in the Volga Federal District in 100.0% of cities - mobile sources; in the Ural Federal District, 50% of cities have stationary sources and 50% have mobile sources. In the Siberian Federal District, in 62.5% of the cities included in the analysis, stationary sources make the main contribution to the anthropogenic load. In cities with a population of 0.5-1 million people, the ratio of monetary income to the subsistence level and the number of doctors per 10,000 population is higher than in cities with population of 250-500 thousand. Limitations. Limited access to quantitative data and time periods. Conclusions. The indicator of anthropogenic load per inhabitant is an informative indicator of the direct impact of atmospheric air pollution on the health of the population in large cities. The ratio of the average per capita income to the subsistence minimum most objectively characterizes the level of material well-being of the population in regions with different levels of economic development. The number of doctors per 10,000 people is an indicator of the inequality of the constituent entities of the Russian Federation in terms of the level of medical provision and the availability of medical care.

Purpose: There is present fear on the swelling incidents of disasters in institutions in this country which makes it necessary to explore the risk assessment in schools. The aim of this research was to explore the influence of risk assessment on security management outcomes in public secondary schools in Mandera County, Kenya.

Methodology: Theories guiding the study were the Stakeholders’ and the Securitization theories. The investigation employed mixed methodology and the concurrent triangulation design. The target population was 400 participants and involved principals, teachers and education officers. This included all the secondary schools and all the 18 education officers in Mandera County and the 58 principals, 324 teachers. Questionnaires were used for teachers while interviews were used for principals on security management outcomes. Quantitative data were analyzed in descriptive statistics and presented by tables, frequencies and percentages. Qualitative data were analyzed by thematically in narrative forms and verbatim citations. Two levels of analysis were employed namely: descriptive and thematic.

Findings: From the research findings, it was clear that there were efforts made to assess risks but there was also need to beef up the same since it was not adequately done. There was lack of visits from the government to enhance safety of students in schools.

Unique Contribution to Theory, Policy and Practice:

The stakeholders’ and the securitization theories were used to alert schools and prepare them for calamities consecutively hence contributing to the issues in the study. The study established that risk assessment needed to be prioritized in spite of the fact that some efforts were being made. It was concluded that more efforts be put on risk assessment. The theories were validated in that there was sensitization to stakeholders and the need to prepare in advance for disasters in schools. It was recommended that the Ministry of Education be active in doing necessary checks on risk assessment and be sending security teams in schools
