Published: March 2019

Introduction. The paper presents the authors’ view on the psychohygiene of the activity in entrepreneurs under which, on the one hand, the assessment of the business environment, on the other one - psycho-prevention and psycho-correction measures to preserve the mental health of the subjects engaged in business are understood. These conditions included economic, psychological, social aspects of entrepreneurship, which tend to cumulate, lead to a blockade of the ability and opportunities for self-development of the individual and subsequently to the emotional burnout syndrome of entrepreneurs. The peculiarities of psycho-correction work and the methods of preventing the emotional burnout syndrome were revealed. Results and their discussion. Among those who appealed for counseling, 67.9% of the entrepreneurs felt psychoemotional, physical and intellectual overloads. The starting mechanism for the formation of preneurotic sub-depressive states included maladaptation in relation to the professional role performed. However, the development of the emotional burnout syndrome is a reversible process, which, in turn, allows being successfully leveled using psychotherapy and psycho-correction. Conclusion. In the development of psycho-prevention and psycho-correction measures to preserve the mental health of the subjects engaged in business, the following ones are fundamental: the work with the entrepreneur to understand his emotional problem, identifying the source of stress from the position of self-organization, training the entrepreneur to grade stress, transforming the problems in favor of his own development. Primary psycho-prevention helps to predict the impact of negative factors on the psyche of entrepreneurs, the secondary one forms the correct perception of negative circumstances and the ability to cope with stress. Time management, the correct organization of the workplace, knowledge of modern technologies enhances the psycho-correction effect. In addition, the basic model of psychological aid to entrepreneurs should be complemented by anti-stress management training.

Nowadays, the aging of the population is one of the most important social problems, which in many ways changes the economic, industrial and social relations of the modern world. There are five groups of risk factors for aging: the genetic factor, the way of life, work, the environment, the level of medicine. In different countries, in different cities of the same country, the distribution of the share of influence of aging risk factors on the human body is different. Depending on which of the five groups of risk factors are assumed to be a priority in the region under study, this aspect should be addressed by the organizational, medical, financial and preventive activities of the necessary structures of the region. In this paper, an attempt was made to identify the priority group of aging factors of the human body, characteristic of the Voronezh region. In doing so, we carry out a comparative analysis of the priority group of aging factors in the human body, with a distinction between urban and rural populations. The conducted research is especially important for the Voronezh region since it is one of the ten most unfavorable subjects of Russia in terms of demographic aging. So in Voronezh in 2016 the proportion of elderly people (60 years and older) accounts for 17%. In our work, the degree of aging of the population was determined using the method of determining the biological age developed by Voitenko V.P. The essence of the work was to determine the degree of aging of each participant in the study using the Voitenko V.P. method, taking into account his level of health, lifestyle, financial support. All respondents were divided into two groups. The first group includes elderly people who live in the city; the second group was the rural population. In conclusion of the work, a comparative analysis of the two groups was made in terms of the degree of aging of the population, highlighting the priority risk factor characteristic of the Voronezh region.

Published: March 2019

The increasing pollution of the environment is one of the most important causes of modern environmental problems. In Russia, a number of regions are forming where a high concentration of population, industrial and agricultural production has led to a sharp deterioration in the environmental situation since the resistance of natural complexes to anthropogenic impact is either exhausted or close to this state. Anthropogenic loads in these regions exceed permissible values, creating a situation in which poorly compensated and irreversible changes in landscapes occur, the threat of depletion or loss of water resources is growing. Pollution of surface and groundwater, the increase of water deficit in terms of quantitative and qualitative indices, the formation of zones of a stressful ecological situation determine the need for the formation of new approaches to solving water use problems. Anthropogenic loads in these regions exceed permissible values, creating a situation in which poorly compensated and irreversible changes in landscapes occur, the threat of depletion or loss of water resources is growing. Pollution of surface and groundwater, the increase of water deficit in terms of quantitative and qualitative indices, the formation of zones of a stressful ecological situation determine the need for the formation of new approaches to solving water use problems. Anthropogenic impact on surface and groundwater occurs as a result of natural or artificial processes and leads to a deterioration of the functions of the aquatic environment with respect to any biological or technological object. In this paper, an environmental assessment of the chemical composition of thawed and rainwater from the residential areas of Voronezh is presented. By the degree of pollution, the surface runoff can be located in the next descending series: autumn runoff - melt flow - spring runoff. Chemical analysis of priority pollutants in surface runoff samples was carried out using the following analytical methods: colorimetric; titrimetric; calculated; potentiometric; weight; fluorometric.

Published: March 2019

There were performed studies of the interaction of collagen of freshwater fish with water to determine the prospects for its use as an absorbent layer of personal care products, a method for treating freshwater fish skins for obtaining a material with an increased water-absorbing capacity has been developed; thermal stability, allergenic properties of this material have been studied; toxicity tests have been carried out. Methods of thermogravimetry, differential scanning calorimetry, spectroscopy in the visible and ultraviolet region of the spectrum of light waves were used. Allergenicity was determined by the method of cutaneous applications, toxicity - according to State Standards. The most part of moisture was shown to be bound by adsorption or osmotic pathways, only 7% of moisture bound by the samples is retained in the capillaries. The sufficiently high binding energies of about 4 J/mol suggest the ability of the functional groups of fish collagen to create a powerful hydrated membrane. For the loosening of the material, sequential treatment of fish skin in weak solutions of alkalis and organic acids is suggested, after which the swelling capacity reflecting the moisture capacity of the material rises by almost 10 times and amounts to 30 g per 1 g of dry matter. The aggregation of polydisperse systems of processed collagen in the temperature range of 38◦-46◦, which can lead to a decrease in moisture capacity with an increase in temperature to these values, is found. The obtained material has no allergic neither toxic effects. As a result of the studies, it was shown that collagen of freshwater fish, modified by treatment in alkali and organic acid solutions, can be used as a material for the absorbent layer of personal care products under the condition of sparing temperature regimes during their manufacture.

The purpose of this study was to investigate the status and main trends of the prevalence of diseases of the eye and its appendages in medical university students with the detection of priority risk factors of the educational environment. Materials and methods. The method of investigation included several stages. The general population was analyzed (official statistical data of the ophthalmologic service of the Voronezh Region Health Department (statistical forms No. 12, 14, 14 SD, 30)), and selective studies were conducted (based on the copying and analysis of data from outpatient charts and case histories). A total of 1500 study cards were filled out, the total number of visits amounted to 3200. In the second stage of the study, a sociological survey was conducted on a specially developed questionnaire consisting of 46 questions grouped into 5 blocks. In total, 1950 respondents were surveyed. Statistical processing is performed on the basis of statistical analysis software package and the Chart Wizard in Microsoft Excel 2010, as well as the STATISTICA 6.0 application package. Results. Our studies have made it possible to refine and supplement the current data on the prevalence of diseases of the eye and its appendages among students in the Voronezh region, which can be used as a basis for planning activities to improve specialized ophthalmic care for this population category. Eye diseases were shown to be a fairly common pathology among students, and those who study at the medical school have their own characteristics that require serious measures to improve the system of epidemiological surveillance of this pathology. The surveillance system should include monitoring the impact of various risk factors and timely elimination of adverse events. To this end, in educational institutions, it is important to observe ergonomic requirements for the organization of workplaces, to observe the time of providing breaks for rest during the school day, to establish their duration and arrange for these breaks taking into account the training course, load volume and hygienic characteristics of the classrooms, where classes are held. It should not be forgotten that the leading role in the prevention of the negative impact of non-favorable factors is assigned to the very contingent of students who must be able to take individual preventive measures and observe personal hygiene rules. In this regard, the educational organizations need to repeatedly increase the amount of work on hygiene education and the education of young people.

Published: March 2019

Introduction. The shell of chicken eggs has long been used as a natural source of calcium in various food, feed, and pharmaceutical industries. There is a perspective to obtain soluble forms of calcium from the eggshell in the form of ascorbates, citrates, lactates, used in food technology as food additives that are obtained chemically. To date, the volume of eggshell produced in Russia is about 215 thousand tons per year, but the solubility of calcium from the shell is low, which does not allow the widespread use of this by-product of domestic production. One of the ways to increase the solubility of calcium can be considered the application of the process of mechanoactivation of the shell. The purpose of the study was to investigate the effect of the disintegration-wave action on the solubility of calcium shell eggs in organic acids in order to obtain soluble forms of ascorbates, lactates, and citrates. Methods. The prepared shell of chicken eggs was milled on a disintegrator of the FED “Cedar 3601” grade and placed in solutions of organic acids until the calcium concentration values, determined by atomic-emission spectrometry with inductively coupled plasma (AES-ISP) using an Optima 2000 atomic emission spectrometer DV (Perkin Elmer) became constant. Results. The existing data on the effect of mechanoactivation on the process of increasing the solubility of substances are analyzed. The effect of the disintegration-wave action on the solubility of the eggshell in organic acids is studied. Discussion. The disintegration-wave action was found to have a significant effect on the solubility of the eggshell eggs in citric lemon, ascorbic and lactic acids. The greatest effect of mechanoactivation was established to be achieved with a two- or three-fold disintegration-wave action. The maximum solubility was observed at pH = 2.0-3.0. The maximum solubility was observed when dissolved in ascorbic acid at 90°C, and in lactic and citric acids - at 60°C. Conclusion. Soluble forms of calcium obtained in the form of ascorbates, citrates, lactates, can be used in food technology as food additives. The application of the method of disintegration-wave action on the eggshell was established to increase the solubility of calcium in it. There are determined optimal settings, at which the maximum achievable values of calcium concentrations in systems are reached.

Health Crisis in Rural Nepal due to the Shortage of Health Professionals: Challenges, Solutions, and the Role of the International Community
Authors: Shrestha Biswas , Shrestha Binita
Published: March 2019

Nepal, considered one of the poorest and underdeveloped nations in the world, has a particularly pronounced health crisis in its rural areas due to extreme shortages of health professionals. Home to 80% of the total population, the rural parts of Nepal are estimated to have a physician ratio of 2.4 physicians per 100 000 people (1), about 100 times lower than the minimum acceptable ratio provided by the World Health Organization (6, WHO 2006). The challenges of the mountainous topography of this Himalayan nation are further compounded by the disastrous scarcity of health professionals, viz. doctors, nurses, public health and biomedical researchers, etc. Consequently, simple and easily treatable diseases such as diarrhea, cholera, etc. take the lives of thousands of Nepali villagers every year. The health status and quality of life along with other grave problems such as poverty, illiteracy, and lack of infrastructures of development are worse in rural areas around the world, especially in developing nations such as Nepal compared to urban areas in developed nations (13, 18). Health crisis, underdevelopment, and poverty entangle rural areas in developing nations in a vicious circle, each contributing to the other, in which ill-health of rural residents negatively affects their productivity, economic output, socio-cultural contributions, and participation in the competitive world of globalization. The health crisis in rural parts of Nepal exists due to the extreme shortage of health professionals resulting from their preferences for working in urban cities in Nepal and in other developed nations, is caused by an intricate fabric of domestic push factors and international pull factors and can only be addressed through sustained cooperation between the national and international bodies.

Published: March 2019

Long non-coding RNAs (lncRNAs) have been found to be involved in many biological processes, including the regulation of cell differentiation, but a complete characterization of lncRNA is still lacking. Additionally, there is evidence that lncRNAs interact with ribosomes, raising questions about their functions in cells. Here, we used a developmentally staged protocol to induce cardiogenic commitment of hESCs and then investigated the differential association of lncRNAs with polysomes. Our results identified lncRNAs in both the ribosome-free and polysome-bound fractions during cardiogenesis and showed a very well-defined temporal lncRNA association with polysomes. Clustering of lncRNAs was performed according to the gene expression patterns during the five timepoints analyzed. In addition, differential lncRNA recruitment to polysomes was observed when comparing the differentially expressed lncRNAs in the ribosome-free and polysome-bound fractions or when calculating the polysome-bound vs ribosome-free ratio. The association of lncRNAs with polysomes could represent an additional cytoplasmic role of lncRNAs, e.g., in translational regulation of mRNA expression.

Monitoring jantung telah populer sejak 5 tahun terakhir. Hal ini ditandai dengan munculnya berbagai produk monitoring jantung berbasis wearable sensor. Umumnya komunikasi yang digunakan pada sistem tersebut adalah menggunakan radio telemetri dengan biaya opera- sional yang mahal. Beberapa riset mencoba menggunakan konsep internet of things (IoT) untuk mengatasi hal tersebut. Namun demikian, desain komunikasi IoT yang ada belum efisien. Ini disebabkan riset yang ada hanya berfokus pada bagaimana hasil baca sensor dapat dipantau secara realtime. Untuk mengatasi hal tersebut, riset ini mengusulkan sebuah arsitektur IoT berbasis cloud untuk memonitor aritmia, salah satu jenis penyakit jantung yang umum ditemukan. Deteksi aritmia yang diusulkan adalah pengembangan algoritma deteksi aritmia berbasis Tsipuras et al, dengan menggunakan deteksi fitur R. Sistem yang diusulkan pada paper ini telah diuji menggunakan dataset MIT-BIH dan menghasilkan akurasi 93.11% terhadap 3 kelas aritmia, yaitu PAC, PVC dan VT. Menariknya, dengan penerapan IoT, efisiensi algoritma deteksi fitur R meningkat 30% dibanding yang diusulkan oleh Pan dan Tompkins. Terbukti dengan rendahnya waktu rata-rata eksekusi tiap sampel data, yaitu sekitar 0.00749 ms.

Voice over Internet Protocol (VoIP) adalah teknologi yang menggunakan internet untuk melakukan komunikasi jarak jauh. VoIP berkembang seiring dengan berkembangan teknologi smartphone  yang pesat. Hal ini menyebabkan komunikasi menggunakan telepon konvensional sudah mulai ditinggalkan. Perkembangan teknologi VoIP yang pesat dengan penggunanya yang sudah sangat banyak mengakibatkan kemungkinan terajadinya bufferbloat pada jaringan. Permasalahan ini dapat diatasi dengan mekanisme pengatur antrian atau biasa disebut Active Queue Management (AQM). Ada berbagai macam AQM yang sudah dikembangkan seperti Proportional Integral controller Enhanced (PIE), Controlling Delay (Codel), DropTail dan sebagainya. Pada penelitian ini diimplementasikan dan dianalisis kualitas layanan VoIP dengan menerapkan Proportional Integral controller Enhanced (PIE) dan DropTail. Pengukuran kualitas dinilai dengan menggunakan metode perhitungan Mean Opinion Score (MOS). Penilaian terbagi menjadi dua yaitu secara subjektif dan objektif. Secara subjektif, nilai MOS didapatkan dengan mendengarkan langsung kualitas suara. Secara Objektif, nilai MOS didapatkan dengan perhitungan R-Factor. Hasil pengujian perbandingan nilai Mean Opinion Score (MOS) baik secara subjektif maupun objektif menunjukan bahwa kualitas VoIP dengan algoritma Proportional Integral Controller Enhanced (PIE) lebih baik daripada DropTail. Pada parameter throughput, packet loss, maupun delay PIE lebih juga lebih baik daripada Droptail. Ini mengindikasikan implementasi algoritma PIE terhadap layanan VoIP lebih baik daripada Droptail

Authors: Naa Christian Fredy
Published: March 2019

In this article, the Ising model has been modified to simulate the effect of particle size on magnetic nanoparticles properties especially hole-doped manganites. The objective of this research is to give an insight and clear understanding about magnetic nanoparticles especially the effect of the particle size. The model considers common accepted magnetic nanoparticles theoretical model where each particle consists of core and surface/boundary part. The model mimics the particles size as a clusters or group of spins. The spins were designated as either core or boundary particles and differs for their exchange energy. The model predicts magnetization, coercivity, hysteresis and magnetic characteristics of core and boundary of the nanoparticles. The results are in a good agreement qualitatively with experimental results. The model also gives insight to the micro-states of the spin at each clusters for zero-field-cooled experiment.
Data-Driven Modeling of Carbon Dioxide Corrosion for Integrity Management Application
Authors: Mnasri Hamdi , Wassar Taoufik , Franchek Matthew A. , Marotta Egidio (Ed)
Published: March 2019

In this work we expand on the carbon dioxide (CO2) corrosion–rate model presented by DeWaard et al. (1995) using a parameter–varying (PV) approach to improve prediction accuracy. Specifically, the constant coefficients of the reaction–kinetics–dependent term are replaced with varying parameters presented as a function of mean flow velocity and pH. On the basis of experimental data provided by Nešić et al. (1996) and Dugstad et al. (1994), we compare the corrosion–rate predictions between the original model and the proposed model. A significant improvement of the correlation coefficient (R2) from 0.54 to 0.90 is achieved when the PV coefficients replace the constant coefficients. Accurate predictions of the CO2 corrosion rate affect useful life forecasting of oil and gas systems during front-end engineering design studies, facilitate condition-based maintenance, and serve as the basis for the creation of a digital twin for this process.

Published: March 2019

Background

Postoperative pulmonary complications (PPCs) have been the most common perioperative complication following surgical site infection, which prolongs the hospital stay and increases health care cost. Lung-protective ventilation strategy is considered better practice in abdominal surgery to prevent PPCs. The role of inspiratory oxygen fraction (FiO2) in the strategy is currently not clear and remains disputable, despite liberal oxygen administration and hyperoxia is demonstrated to be associated with respiratory mechanism changes and increased mortality in ventilated patients. The trial aims at exploring the effect of FiO2 in lung-protective ventilation strategy on PPCs.

Methods

PROtective Ventilation with a low versus high Inspiratory Oxygen fraction trial(PROVIO)is a single-center, prospective, randomized, controlled trial planning to recruit 252 patients under abdominal surgery lasting for at least 2 hours. The patients are randomly assigned to (1) a low FiO2 (30% FiO2) group and (2) a high FiO2 (80% FiO2) in lung-protective ventilation strategy. The primary outcome of the study is the occurrence of PPCs within the first 7 days postoperatively. Secondary outcomes include the severity grade of PPCs, the occurrence of postoperative extrapulmonary complications and all-cause mortality within the first 7 and 30 days postoperatively.

Discussion

PROVIO trial specially assesses the effect of low versus high FiO2 in lung-protective ventilation strategy on PPCs and the results will provide practical approaches to intraoperative oxygen management.

Background

Metabolic Syndrome (MetS) associated with cardiovascular diseases have been focused on by researchers. Although various studies have investigated its relationship with the oral environment, the effects of dental interventions for MetS remain unclear. The aim of this trial is to investigate whether prosthetic or periodontal treatment combined with dietary and exercise advice can improve waist circumference, a surrogate measure of the syndrome. The null hypothesis is that there will be no difference in waist circumference between participants who receive prosthetic or periodontal treatment combined with dietary and exercise advice and those who receive only dietary and exercise advice.

Methods

This is a single-center, single-blinded, parallel, randomized controlled trial. Participants are randomly allocated to an intervention group (dietary and exercise advice plus prosthetic or periodontal treatment) or a control group (dietary and exercise advice only). Outcome measures include waist circumference; blood pressure; serum triglyceride, serum HDL/LDL cholesterol, fasting blood glucose, and HbA1c assessment using blood tests; Anthropometric measurements using bioelectrical impedance; health-related quality of life assessment using MOS 36-Item Short-Form Health Survey; oral-health-related quality of life assessment using Oral Health Impact Profile-14 and Geriatric Oral Health Assessment Index; food and nutrient intake assessment using brief-type self-administered diet history questionnaire; periodontal assessment using probing pocket depth and bleeding on probing. Objective masticatory function assessment using a color-changeable chewing gum and a gummy jelly was conducted for the participants who received prosthetic treatment. Outcome measures are to be implemented at three time points: at baseline and at 1 and 3 months after intervention. Differences between two groups in each assessment is compared using the Student’s t-test. Within group, the change between each assessment time is compared using the Tukey’s test.

Discussion

This trial could help to establish a new preventive method for the MetS that can be delivered by dental practitioners. Moreover, the findings are expected to reinforce the contribution of dentistry to extending healthy life expectancy.

Background

South Africa is among the 7 highest tuberculosis (TB) burden countries. Harmful lifestyle behaviours, such as smoking and alcohol, and poor medication adherence can affect clinical outcomes. Modification of these behaviours is likely to improve TB treatment outcomes and has proven possible using motivational interviewing (MI) techniques or use of short message service (SMS) text messaging. There have been no studies assessing the effect of combined MI and SMS interventions on multiple lifestyle factors and TB treatment outcomes.

Methods

This is a prospective, multi-centre, two-arm individual randomised controlled trial looking at the effectiveness and cost-effectiveness of a complex behavioural intervention (the ProLife programme) on improving TB and lifestyle-related outcomes in 3 provinces of South Africa. The ProLife programme consists of an MI counselling strategy, delivered by lay health workers, augmented with subsequent SMS. We aim to recruit 696 adult participants (aged 18 years and over) with drug-sensitive pulmonary TB who are current smokers and/or report harmful or hazardous alcohol use. Patients will be consecutively enrolled at 27 clinics in 3 different health districts in South Africa. Participants randomised individually to the intervention arm will receive 3 MI counselling sessions 1 month apart. Each MI session will be followed by twice-weekly SMS messages targeting treatment adherence, alcohol use and tobacco smoking, as appropriate. We will assess the effect on TB treatment success, using standard World Health Organization (WHO) treatment outcome definitions (primary outcome), as well as on a range of secondary outcomes including smoking cessation, reduction in alcohol use and TB medication and anti-retroviral therapy adherence. Secondary outcomes will be measured at 3 and 6 months follow-up.

Discussion

This trial aligns with the WHO agenda of integrating TB care with the care for chronic diseases of life-style, such as provision of smoking cessation treatments, and with the use of digital technologies. If the ProLife programme is found to be effective and cost-effective, the programme could have significant implications for TB treatment globally and could be successfully implemented in a wide range of TB treatment settings.
A case report: autosomal recessive limb girdle muscular dystrophy caused by a novel mutation (c. 287A > G) in POMT2 gene of a Chinese Han patient

Published: March 2019

BACKGROUND

Autosomal recessive limb girdle muscular dystrophy 2N is caused by mutations in the POMT2 gene. The disease is characterized by proximal muscle weakness,with minimal progression, with cognitive impairment,a significantly elevated serum level of creatine kinase.

CASE PRESENTATION

A 9-year-old boy presented with proximal muscle weakness since the last 4 years,with minimal progression.There was no significant family history.Medical examination showed no generalized muscle hypertrophy. Serum creatine kinase level was 52-fold higher than the normal value. Wechsler Intelligence scale for Children (WISC, 4) suggested mild cognitive impairment (IQ =74). DNA sequence analysis identified a novel missense mutation (c. 287A > G) and a known mutation (c. 1261C > T).

CONCLUSIONS

This case report of autosomal recessive limb girdle muscular dystrophy 2N caused by a novel compound heterozygous mutation expands the genotypic spectrum of POMT2 gene.

Published: March 2019

Global vegetation dynamics is a significant phenomenon being monitored from space. This study attempts to establish relationship among vegetation changes and land surface temperature using the data derived from satellite products in the Middle Ganga Plain, India using python programming. Ten years of MODIS Land Surface Temperature (LST) on board Terra, Normalized Difference Vegetation Index/Enhanced Vegetation Index (NDVI/EVI) (1km spatial and 8-days composite temporal resolution for LST and 250m spatial and 16-days composite for NDVI/EVI) has been used in this study. The average LST for the month of January was 23.0°C which fell to 15.7°C for the same month in 2015; whereas in March it was recorded to be 35.3°C and reduced to 32.3°C in 2015. Mean NDVI value has been recorded to be 0.44 in January 2000 which has slightly increased to reach 0.50 for the same month in 2015. For the month of September, it was recorded at 0.49 in 2000 and 0.52 for the same month in 2015. This paper attempts to analyze the spatio-temporal distribution and empirical relationship of vegetation cover and LST using Python.
