THE AIMS OF THE PAPER

As customers' needs are changing very rapidly, it is important for all growing enterprises not only to provide high-quality products/services but also to exceed the customers’ own expectations. Businesses need to change their marketing strategies to meet their customers’ expectations, including brand management strategy which plays a vital role in conveying the value of products/services to potential customers. To increase the competitive advantage of Vietnamese enterprises in integrating with the international economy, there is a need for innovation in brand management. It is necessary to provide the concept of the brand-building process to the businesses as overview; it is vital to apply it in the planning and implementation of brand management strategy in Vietnamese enterprises.

METHODOLOGY

This empirical study has been analyzed and is presented for the future use in the concept of brand building process towards Vietnamese Enterprises. This paper was conducted in two phases. In the first phase, the researcher uses a qualitative approach to interview experts, administrators, who conduct the research on the marketing field to discuss how the phases and procedures to build a brand for the new era for Vietnamese enterprises. There were 12 experts selected to discuss to gain the model for the concepts in brand building for this new era. There were (6) questions discussed with the experts to collect the research data relative to the brand building process. Preceding this, the researcher gathered the opinions of these marketing experts to gain an overview of the process to create branding building.  

MOST IMPORTANT RESULTS

The researcher summarizes four critical phases in the brand-building process for Vietnamese businesses in the new era. There are four necessary phases in building a brand as follows: (1) brand identity, (2) brand awareness, (3) brand love, and (4) brand loyalty. Depending on the strategy of the business that can be applied in the brand-building process in each individual phase or the brand- building process can combine four phases concurrently in building a branding strategy.

RECOMMENDATIONS

From the outcomes of this study, the researcher recommends that practitioners, as well as scholars can apply and research based on this study to improve in branding for businesses for sustainable development purposes in the new era.

A recent change in the ISO 7206-2, Implants for Surgery – Partial and Total Hip Joint Prostheses – Part 2: Articulating Surfaces Made of Metallic, Ceramic and Plastics Materials, with regard to hip joint prostheses, altered the recommended cutoff for measuring the roughness of the articulating surfaces of the femoral head and acetabular cup but did not encompass two key sites: the bore head and the trunnion. The aim of this study was to evaluate whether the standardized parameters and sites established in ISO 7206-2 are appropriate for evaluating the quality of the surface finish of total hip arthroplasty implants. Three kits containing the polymeric acetabular components, metallic heads, and stems from 5 manufacturers were used for testing. Contact profilometry was performed on the internal acetabular cup, external head, head bore, and trunnion surfaces. Additionally, the external head surface was evaluated with an interferometer to increase the accuracy. The evaluation of the external surface of the femoral head with a profilometer seems to be inadequate, because of a limitation of the contact method associated with highly polished surfaces. The average roughness (Ra) values obtained with an interferometer were lower than those measured with the profilometer and revealed significant differences between the manufacturers. The use of an 0.80-mm cutoff is more appropriate for the Ra range normally found for acetabular cups, enhancing the power to detect acetabular cups with inadequate roughness. The absence of a standard for the surface finish of the stem-head interface generates heterogeneity between manufacturers and between samples produced by a single manufacturer, revealing a lack of quality control.

The acquisition of neuronal polarity is a complex molecular process that depends on changes in cytoskeletal dynamics and directed membrane traffic, regulated by the Rho and Rab families of small GTPases, respectively. However, during axon specification, a molecular link that couples these protein families has yet to be identified. In this paper, we describe a new positive feedback loop between Rab8a and Cdc42, coupled by Tuba, a Cdc42-specific guanine nucleotide-exchange factor (GEF), that ensures a single axon generation in rodent hippocampal neurons from embryos of either sex. Accordingly, Rab8a or Tuba gain-of-function generates neurons with supernumerary axons whereas Rab8a or Tuba loss-of-function abrogated axon specification, phenocopying the well-established effect of Cdc42 on neuronal polarity. Although Rab8 and Tuba do not interact physically, the activity of Rab8 is essential to generate a proximal to distal axonal gradient of Tuba in cultured neurons. Tuba-associated and Rab8a-associated polarity defects are also evidencedin vivo, since dominant negative (DN) Rab8a or Tuba knock-down impairs cortical neuronal migration in mice. Our results suggest that Tuba coordinates directed vesicular traffic and cytoskeleton dynamics during neuronal polarization.

SIGNIFICANCE STATEMENTThe morphologic, biochemical, and functional differences observed between axon and dendrites, require dramatic structural changes. The extension of an axon that is 1 µm in diameter and grows at rates of up to 500 µm/d, demands the confluence of two cellular processes: directed membrane traffic and fine-tuned cytoskeletal dynamics. In this study, we show that both processes are integrated in a positive feedback loop, mediated by the guanine nucleotide-exchange factor (GEF) Tuba. Tuba connects the activities of the Rab GTPase Rab8a and the Rho GTPase Cdc42, ensuring the generation of a single axon in cultured hippocampal neurons and controlling the migration of cortical neurons in the developing brain. Finally, we provide compelling evidence that Tuba is the GEF that mediates Cdc42 activation during the development of neuronal polarity.

Published: January 2021

Objective: Acupoint catgut embedding (ACE) has been used safely for thousands of years in traditional Chinese medicine. The aim of this study was to assess whether ACE can improve insulin resistance and promote rapid recovery after open cardiac surgery.
Methods: A group of 200 patients undergoing cardiac surgery were randomly allocated to receive either ACE (ACE group) or sham ACE (SHAM group).
The primary outcome of our trial was insulin resistance assessed 1, 3, 5, and 7 days after surgery. The homeostasis model assessment (HOMA-IR) was used to measure perioperative insulin resistance. Secondary outcomes included insulin, glucose, and inflammatory cytokine (interleukin (IL) 6 and IL-8) levels; time to extubation; incidence of infection; time to first feces; acute kidney injury; incidence of postoperative nausea and vomiting (PONV); length of stay in the ICU; length of hospital stay; and other clinical parameters.
Results: The ACE group had lower insulin, glucose, IL-6, IL-8, and HOMA-IR levels than the SHAM group one week after the operation. The incidence of infection, incidence of PONV, time to drain removal, and length of hospital stay significantly were lower in the ACE group than in the SHAM group.
Conclusion: ACE can improve insulin resistance and promote rapid recovery after open cardiac surgery.

Aims. To evaluate the effects of the clinical predictors such as age, duration of disease, sex, and smoking on the frequency of relapses in IBD patients.

 Methods. This study recruited 289 IBD (133 with CD and 156 with UC) patients. All were followed-up for 36 months for relapses of the disease. We defined as frequently relapsing (≥1/year) patients with at least one relapse per year and as infrequently relapsing those with less than one relapse per year (<1/year). We assessed the effect of the clinical predictors: age, duration of disease, sex, and smoking on the frequency of relapses in IBD patients.

 

Results. Sixty-four (48.1%) of the CD patients were frequently relapsing and 69 (51.9%) were infrequently relapsing. There was a significant association between the age and the frequency of relapse (p=0.001; OR 0.964; 95% CI 0.941-0.987, p=0,002) and between the duration of the disease and frequency of relapse (р<0.001; OR 0.740, 95% CI 0.655-0.837, p<0.001). Seventy-two (46.2%) of the UC patients were frequently relapsing and 84 (53.8%) were infrequently relapsing. There was a significant association between the age and the frequency of relapse (p=0.001; OR 0.964, 95% CI 0.941-0.987, p=0.002) and between the duration of the disease and frequency of relapse (р<0.001; OR 0.740, 95% CI 0.655-0.837, p<0,001).

 Conclusion. We demonstrate in a relatively significant cohort of IBD patients that young age and short duration of the disease are associated with more frequent relapses.

Introduction. In recent years a link between periodontitis and cardiovascular diseases has been proposed. Oxidative stress has been found to be involved in their pathophysiology.

Objectives. The aim of this study was to demonstrate that a wire ligature placed around the first mandibular molars of the rat causes inflammation in the periodontium and lipid deposits in the aorta, via oxidative stress.

Methods. Twenty male Wistar rats were divided randomly into two groups of 10: Control group and Periodontitis group. An orthodontic wire ligature was placed around the cervix of the first mandibular molar and was kept in place for 4 weeks. Clinical attachment loss was determined to assess the gingival recession. Aorta was harvested after 4 weeks and the malondialdehyde (MDA) levels in the aorta tissue homogenate were determined. Lipid deposits were evaluated using Oil Red staining and immunofluorescence under confocal microscopy. Total lipid deposits in the aorta were assessed using a computer morphometry system.

Results. Significant gingival recession was observed in the Periodontitis group in comparison with the Control group. Increased MDA levels were present in the aorta in the ligatured rats in comparison with the Control group. Significant lipid deposits were observed in the aorta of the Periodontitis group as opposed to the Control group.

Conclusions. The affixing of an orthodontic wire ligature produces gingival recession, increased oxidative stress and lipid deposits in the rat descending aorta.

Background: In Huntington’s disease psychiatric symptoms may manifest prior to motor dysfunction. Such symptoms negatively impact people’s quality of life and can worsen the course of the primary disease. The aim of the present study was to assess and compare depression, anxiety and hopelessness rates in individuals with and without an abnormal expansion of CAG repeats in the huntingtin (HTT) gene and healthy controls.Materials and methods: Study involved 31 individuals referred for genetic testing for Huntington’s disease and a control group of 41. Depressive and anxiety symptoms were assessed using Beck Hopelessness Scale (BHS) and Hospital Anxiety and Depression Scale (HADS). Results between groups were compared using the Mann–Whitney U test. Two-sided Bonferroni corrected p-value was set at ≤0.017.Results: Individuals with HTT gene mutation (“gene mutation positive”, GMP) (N=20) scored higher on the HADS depression subscale (5.90 ± 4.52 vs 1.36 ± 1.91; p ≤ 0.017) than those without HTT gene mutation (“gene mutation negative”, GMN) (N=11). GMP and control groups scored higher than the GMN group on the BHS (5.65 ± 3.91 vs 2.09 ± 1.64 and 5.27 ± 4.11 vs 2.09 ± 1.64, respectively; p ≤ 0.017). No differences in anxiety levels were found.Conclusions: Depressive symptoms and hopelessness were more prevalent in individuals with HTT gene mutation than in individuals who were tested but had no said mutation. Such results emphasise the importance of timely diagnosis and treatment of psychiatric comorbidities in individuals affected by Huntington’s disease.

Coal dust leakage from coal stacks leads to intensive contamination of the working areas. Therefore, determining level of air pollution near the coal piles for various meteorological situations, when new coal piles are arranged, is an important applied problem. For practice, it is necessary to have quick-calculating mathematical models whiсh take into account the most significant physical processes impacting on formation of contamination zones near the coal piles. Today, to predict the level of air pollution at dust leaking from the coal stacks, the normative technique OND-86 or the Gauss model is used. These forecasting methods make it possible to quickly calculate the contamination zones, but they do not take into account geometric shape of the coal stack and unevenness of the velocity field near it. The subject of this research was creation of a mathematical model for predicting the level of air pollution near coal piles with taking into account the aerodynamics of air flows around them. The purpose of the work was to develop a set of numerical models for quick calculation of the level of air pollution at coal dust leaking from the coal piles with taking into account the uneven emission of dust from different areas of the stack surface. The modelling equations are the three-dimensional mass transfer equation (Marchuk's model) and the three-dimensional equation for the velocity potential. The Marchuk's model allows taking into account rate of the coal dust particles settling, parameters of turbulent diffusion and uneven air flow rate near the coal pile. The Dirac delta function is used for modelling coal dust leaking from various sections of the coal pile. For the numerical solution of the mass transfer equation, a difference splitting scheme is used. On the basis of the three-dimensional equation for the velocity potential, an uneven velocity field near the coal pile is determined. The Richardson method is used for numerical solution of the three-dimensional equation for the velocity potential. An algorithm for solving the problem of calculating a level of contamination of working areas near a coal pile is considered. The description of the structure of the created complex of computer programs is given.

The author presents the results of a comprehensive assessment of working conditions and functional systems of the body of workers in the conditions of by-product coke production. Harmful factors of the working environment negatively impacting on the health indicators of workers, which is reflected in the high values of morbidity with temporary disability. Quantitative criteria for identifying risk groups and disability were determined depending on the professional group, work experience, gender and age. To calculate the risk range, the method of rationing of intensive indicators was used, which makes it possible to assess the effect of production on the morbidity of workers, as well as to use the results obtained for a comprehensive integral assessment of the likelihood of the risk of disability in the studied professional groups. Ranges of risk have been obtained, which will help to identify "risk groups" among workers requiring examination and preventive measures. Equations of multiple regressions for complex integral risk assessment are obtained, risk forecast for the studied professional groups is calculated. The developed mathematical model and equations of multiple regressions make it possible to calculate the stress levels of the functional systems of the body, to quickly assess the performance of a person both at the time of examination and in production conditions. The proposed method for assessing the impact of working conditions on health indicators can be used at mining enterprises when certifying workplaces and assessing working conditions. The developed methodological recommendations are used in the educational process to improve the quality of scientific research, to analyze the results obtained, as well as in production to simplify the procedure for assessing the impact of harmful production factors on workers and the scientific organization of labor.

When studying risk factors in coal mines, it is necessary, in the first place, to consider factors and properties of the rock massif occurred with the deepening of mining operations in the coal mines, and determine one of the main types of danger: risk of geodynamic phenomena. The geodynamic phenomena occur and develop under the influence of natural and technological factors. Natural factors determine the rock massif proneness of ato geodynamic manifestations or, in other words, its potential danger due to these phenomena. Occurrence of this danger depends on technological factors. Among the dangerous factors of underground coal production to which primarily belong the geodynamic phenomena, the main ones are gas-dynamic phenomena, which are the most complex by their nature and dangerous by consequences due to high dynamic power and release of great amount of gas during a short period of time. Their consequences can be accidents due to sudden gassing and blockage of workings by coal and rock, explosions of methane and coal dust, destruction of the roadway supports, damage of machines and mechanisms, equipment and devices. As the gas-dynamic phenomena in the rocks massif are accompanied by occurrence of various processes differed by their nature, therefore, risks caused by them should be taken into account at mining operations. When considering the gas-dynamic phenomena attention should be paid to the shock wave propagation, as it is one of the gas dynamic processes. Therefore, purpose of this research was to study specific features of the shock wave propagation in the rock massif in order to prevent dangerous consequences. In this article, the authors consider the processes which occur in the rock massif prone to dangerous gas-dynamic phenomena at the shock wave propagation. The methods of rock mechanics, mechanics of continuous media, gas and thermodynamics were used in the research. Analytical researches of processes and numerical analysis of the received results were carried out. It is shown that a sharp increase of thermodynamic parameters under the action of gas-dynamic phenomena can lead to occurrence of the shock waves. It is further established that an explosive air-methane mixture can be formed in cracks, cavities and pores of the face area. At opening the cavities and pores, cases of shock waves formation in air-methane mixture leading to its detonation are possible. Under adverse conditions, this phenomenon can lead to a fire in the roadway.

Purpose is an establishment of efficient parameters of a multi-section man-made deposit at the pulp clays storage on the surface of internal pit dumps during the development of placer deposits. The analytical research method was used to establish the main parameters of man-made deposits sections depending on their width and depth. A graphical research method was used to establish the downtime duration between formation of the first and second sections of the man-made deposit. It is established that division of the man-made deposit into five sections parallel to the mining front reduces time period till start of its operation from 8 to 5 years for it thickness 10 m and from 7 to 5 years at thickness 20 m. However, a significant disadvantage is the increassd number of sections in the man-made deposit from 2 to 5 is an increase in the volume of construction work from 0.27 to 1.11 million m3 at thickness 10 m, and from 0.53 to 2.15 million m3 at thickness 20 m, which confirms the necessity to find an effective number of sections in the man-made deposit and their parameters. The dependence between beginning of the works on filling the man-made deposit and the width of its first section delays start of the filling works, but too small width causes downtime at transiting from the first section to the second one. Efficient width of the man-made deposit first section is established, in which downtime is reduced from 7 years to 5.8 years, and volume of raw materials located outside the pit is reduced by 0.1 - 0.5 million m3 depending on the width of the first section. A method is proposed for determining an effective width of the first section in a two-section man-caused deposit, in which occurs while filling the sections. It is established that effective width of the first section oin the two-section man-made deposit with thickness of 10 m and with parameters of a typical pit development at mining of titanium-zirconium deposit is 241 m.

Published: January 2021

BACKGROUND AND OBJECTIVES:

The Child Opportunity Index (ChOI) is a publicly available surveillance tool that incorporates traditional and novel attributes of neighborhood conditions that may promote or inhibit healthy child development. The extent to which ChOI relates to individual-level cardiometabolic risk remains unclear.

METHODS:

We geocoded residential addresses obtained from 743 participants in midchildhood (mean age 7.9 years) in Project Viva, a prebirth cohort from eastern Massachusetts, and linked each location with census tract-level ChOI data. We measured adiposity and cardiometabolic outcomes in midchildhood and early adolescence (mean age 13.1 years) and analyzed their associations with neighborhood-level ChOI in midchildhood using mixed-effects models, adjusting for individual and family sociodemographics.

RESULTS:

On the basis of nationwide distributions of ChOI, 11.2% (n = 83) of children resided in areas of very low overall opportunity (ChOI score <20 U) and 55.3% (n = 411) resided in areas of very high (ChOI score ≥80 U) overall opportunity. Children who resided in areas with higher overall opportunity in midchildhood had persistently lower levels of C-reactive protein from midchildhood to early adolescence (per 25-U increase in ChOI score: β = .14 mg/L; 95% confidence interval, .28 to .00). Additionally, certain ChOI indicators, such as greater number of high-quality childhood education centers, greater access to healthy food, and greater proximity to employment in midchildhood, were associated with persistently lower adiposity, C-reactive protein levels, insulin resistance, and metabolic risk z scores from midchildhood to early adolescence.

CONCLUSIONS:

Our findings suggest more favorable neighborhood opportunities in midchildhood predict better cardiometabolic health from midchildhood to early adolescence.
EF1-NSGA-III: An evolutionary algorithm based on the first front to obtain non-negative and non-repeated extreme points
Authors: Ariza Vesga Luis Felipe , Eslava Garzón Johan Sebastián , Puerta Ramirez Rafael
Published: January 2021

Multi-Objective and Many-objective Optimization problems have been extensively solved through evolutionary algorithms over a few decades. Despite the fact that NSGA-II and NSGA-III are frequently employed as a reference for a comparative evaluation of new evolutionary algorithms, the latter is proprietary. In this paper, we used the basic framework of the NSGA-II, which is very similar to the NSGA-III, with significant changes in its selection operator. We took the first front generated at the non-dominating sort procedure to obtain nonnegative and nonrepeated extreme points. This opensource version of the NSGA-III is called EF1-NSGA-III, and its implementation does not start from scratch; that would be reinventing the wheel. Instead, we took the NSGA-II code from the authors in the repository of the Kanpur Genetic Algorithms Laboratory to extend the EF1-NSGA-III. We then adjusted its selection operator from diversity, based on the crowding distance, to the one found on reference points and preserved its parameters. After that, we continued with the adaptive EF1-NSGA-III (A-EF1-NSGA-III), and the efficient adaptive EF1-NSGA-III (A2-EF1-NSGA-III), while also contributing to explain how to generate different types of reference points. The proposed algorithms resolve optimization problems with constraints of up to 10 objective functions. We tested them on a wide range of benchmark problems, and they showed notable improvements in terms of convergence and diversity by using the Inverted Generational Distance (IGD) and the HyperVolume (HV) performance metrics. The EF1-NSGA-III aims to resolve the power consumption for Centralized Radio Access Networks and the BiObjective Minimum DiameterCost Spanning Tree problems.

O artigo discute a relevância da utilização de jogos no contexto do atendimento de crianças com dificuldades escolares. Estuda seu potencial como instrumento de observação e de intervenção sustentando-se em duas frentes de análise. Por um lado, examina as contribuições dos jogos de mesa à luz de pesquisas francesas neopiagetianas acerca dos impactos das novas tecnologias no desenvolvimento infantil. Por outro, articula essas discussões com dados oriundos de um Programa de Extensão Universitário destinado a crianças de 7 a 11 anos. O método contemplou a sistematização de 172 protocolos correspondentes a 35 participantes. Os resultados destacam as potencialidades do jogo como instrumento de intervenção, e constatam que o interesse e a persistência, por si sós, não garantem procedimentos satisfatórios na resolução de desafios cognitivos e socioafetivos, ao contrário do que afirma o discurso dos adultos, o qual insiste na falta de esforço e de atenção como causas para as dificuldades escolares.

En este artículo, el objetivo es analizar la forma en que afecta la percepción de la inseguridad al bienestar subjetivo en mujeres y hombres. El estudio fue de carácter cualitativo y se realizó en zonas urbanas de cuatro estados de México. Los resultados muestran que existen diferencias por sexo sobre la valoración de la inseguridad en cada barrio; en el caso de las mujeres su principal preocupación es la seguridad de sus hijos y otros familiares, por tanto,experimentan mayor nerviosismo e intranquilidad, mientras los hombres tienden a minimizar la inseguridad o preocuparse por las pérdidas materiales.

Experimental testbed of the proposed system has been implemented by using cloud and edge computing infrastructure and software defined radio peripheral NI USRP 2900. Simulation results of the network slicing and radio resource management shows that proposed system is able to double the capacity of the physical network infrastructure, while ensuring the target quality of service for all users.
Multidimensional cadastre as an element of participation in modern space management
Authors: Budkowski Szczepan
Published: January 2021

Rapid economic and social development over the last decade has led to many changes in the way space is managed. The dynamically developing cities, complex infrastructure, vertical spatial division, as well as overlapping ownership rights (in 2D terms) resulted in an increase in the demand for the creation of modern space management systems. The aim of the work is an attempt to answer the question concerning the possibility of using a modern real estate cadastre system. The research method used is case study. The method was supported by an analysis of the literature in the field of land and building records and the use of GIS tools in network analyses. The subject of research is the use of data on building interiors. The task was carried out using the available GIS tools. The method of utilising graphic data presented in this article goes beyond the current cadastre functions and can be used, for example, to find a way inside a building.
NRTK measurements with FKP correction method in the subservice NawGeo of ASG-EUPOS
Authors: Kudas Dawid , Wnęk Agnieszka
Published: January 2021

The paper presents the analysis of the accuracy and repeatability of determining the position of the point by the Network Real Time Kinematic (NRTK) technique using the Flächenkorrekturparameter (FKP) concept. The measurement was based on the Active Geodetic Network – European Position Determination System (ASG-EUPOS). The FKP together with Virtual Reference Station (VRS) and Master Auxiliary Concept (MAC) is the currently available method of generating corrections in NRTK technique in NAWGEO sub-service of ASGEUPOS. NRTK positioning using FKP was analysed based on Global Positioning System (GPS) and Globalnaya Navigatsionnaya Sputnikovaya Sistema (GLONASS) signals, because the combination of these satellite systems is currently a common standard. The subject of the study was a 24-hour coordinate time series with a sampling interval of 30 seconds. The collected data was compared with the precise coordinates of the measuring point by calculating the linear deviations and the mean values of X, Y and Z coordinates’ errors and mean position errors for one-hour periods. Selected measures of positioning accuracy were determined, both for threedimensional and horizontal coordinates. An analysis of selected dilution of precision (DOP) factors was also carried out. The analyses were also carried out for coordinates expressed in the horizontal coordinate system and normal heights in force in Poland due to the assessment of the suitability of FKP for geodetic measurements. The experiment showed the expediency of NRTK measurements using FKP corrections generated based on observations from the ASG-EUPOS network for determining real-time position within the territory of Poland.

Relevance. Transition to a low-carbon economy in order to effectively and efficiently exploit the natural resource base of a country is a daunting task, especially for developing countries due to their over-reliance on climate factors. This study focuses on the case of Ghana and assesses the impact of several indicators – agricultural production, economic growth and energy consumption – on the environment. Research objectives. The aim of the study is to describe the causal relationship between agriculture production, economic growth, energy consumption and environmental degradation. Data and Methods. Using time-series data from 1975 to 2014, the study employed the ARDL model to achieve its objectives. Results. The empirical results from the bounds test provide evidence of a long-run association when the covariates are regressed on environmental degradation. The significance of the error correction term at 1% level of significance confirms this assertion. The result further shows that there is evidence of a unidirectional short-run Granger causality and a bidirectional Granger causality among the variables. There was, however, no evidence of Granger causality between economic growth, livestock production index, crop production index and environmental degradation. Conclusion. It is recommended that policy makers should prioritize the adoption of environmentally friendly technologies both in the crop and livestock sub-sectors to ensure that while the food needs of citizens are met, environmental quality is not compromised. Moreover, it is important to ensure energy use efficiency in production.

Relevance. Life expectancy is a comprehensive indicator reflecting the quality of life in a country or region, which is why it is important to estimate the impact of various socio-economic factors on this indicator as accurately as possible. Our study makes a novel contribution to the existing research by conducting a correlation and regression analysis of factors affecting life expectancy in regions of Kazakhstan based on panel data. Research objective. This paper aims to present a modified methodology for estimation of factors affecting life expectancy in regions of Kazakhstan. Data and methods. Our research relies on panel data on regions and cities of Kazakhstan. The data are provided by the Ministry of National Economy and the Ministry of Health Care of the Republic of Kazakhstan. Methodologically, the research is based on regression and correlation analysis. The two main criteria were applied for data selection: availability of statistical data for a sufficiently long period and the potential impact of factors on life expectancy. We built a two-factor power regression model calculated with the help of software package Microsoft Excel. Results. In our research, regression models were used to formulate conclusions concerning the impact of certain socio-economic factors on life expectancy in regions of Kazakhstan. We also brought to light the factors whose relationship to life expectancy requires further investigation. Conclusions. It was found that the most significant factors affecting life expectancy in regions of Kazakhstan are economic ones. The proposed methodology can be used for short- and medium-term predictions of life expectancy.
