ABSTRACT

BACKGROUND: Low availability of medical care and low level of comfort living in rural areas, underdeveloped infrastructure, and difficult working conditions lead to the deterioration of health of rural residents. Rural areas are characterized by less comfortable living conditions than in the city, which can affect health-related quality of life. AIM: The purpose of this study was to assess the satisfaction of the population with the quality of life in rural areas as well as to study the quality of life of the rural population of the Republic of Kazakhstan related to health. METHODS: This study was a one-stage cross-sectional study. Online questionnaire was asked by 411 local residents, of which only 302 were suitable for processing. RESULTS: The results showed that almost a third of the respondents are unemployed (27.2%). In the course of the survey, respondents could subjectively assess their own health, for example, almost a third of respondents (35.76%) assess their health as “poor” and “below average.” At the same time, 18.21% of respondents are not satisfied with the quality of medical services provided in rural areas. The coefficients of correlation between the desire to move to the city and age, income level, family composition, marital status, and type of housing were established. The universal social functioning-36 index was 0.6 (±0.02) for women and 0.55 (±0.033) for men CONCLUSIONS: We can say that the quality of life of the rural population remains quite low. This is evidenced by low income, high unemployment, and the problem of drinking water. Quarantine measures related to COVID-19 also had an impact on the increase in unemployment, however, during the quarantine, there is a deterioration in mental health indicators among men compared to women. The results of the study confirmed that the issue of accessibility of medical services remains very urgent for rural residents.

ABSTRACT

A case study was initiated from the perspective of three research questions: 1) CLIL teachers’ practices at secondary schools of Aktobe during COVID-19 pandemic;2) challenges for the teachers;3) support provided for the teachers. The research methodology combined face-to-face personal interviews, and non-participant observation. Data analysis was conducted in line with Mayring’s (2020) approach to content analysis and by means of categorization into specific themes that emerge from teachers’ conceptualization of their CLIL practices. The analysis of teachers’ reflections on their experiences and challenges of using the CLIL approach during the pandemic, support provided to them and teachers’ attitudes towards the approach is presented in the paper. Research data on the secondary schools Science teachers’ CLIL practices in a remote learning setting was categorized related preparation to teaching, resources used by the teachers, students’ interaction during the lessons, and stakeholders’ attitudes and perceptions of the approach. The obtained data enables to understand Science teachers’ practices in terms of using the CLIL approach in Kazakhstani secondary schools in the period of COVID-19 pandemic, and will contribute to teacher development and preparation for successful CLIL realization in a non-traditional classroom. © 2022 by the authors;licensee CEDTECH by Bastas.

ABSTRACT

The increased prevalence of COVID-19 has had severe implications on the well-being of most organization and professionals most especially in the field of human resource management. This study focused on establishing the impact of COVID-19 on the different human resource practices and future marketing. The main objective of this paper is to suggest the possible ways to solve the negative impact of COVID-19 on the human resource and business management in companies situated in Kazakhstan. It was established that the dynamics of work have greatly changed from the traditional way of working from the organization’s premises to working remotely at home. Consequently, marketing has also shifted to different online platforms since physical contact with customers is currently prohibited to maintain social distancing as one way of preventing coronavirus. These changes have been associated with different negative implications and some positives as some professionals find it more flexible and convenient to work remotely. The COVID-19 data was analyzed in this paper to understand the effect of COVID-19 in the businesses in Kazakhstan. To cope with the current changing times, it is necessary for organization to adjust and adopt the new emerging technologies of working remotely and consequently implement strategic policies and procedures toward maintaining a steady flow. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

ABSTRACT

From March to May 2020, 1306 oilfield workers in Kazakhstan tested positive for SARS-CoV-2. We conducted a case-control study to assess factors associated with SARS-CoV-2 transmission. The cases were PCR-positive for SARS-CoV-2 during June-September 2020. Controls lived at the same camp and were randomly selected from the workers who were PCR-negative for SARS-CoV-2. Data was collected telephonically by interviewing the oil workers. The study had 296 cases and 536 controls with 627 (75%) men, and 527 (63%) were below 40 years of age. Individual factors were the main drivers of transmission, with little contribution by environmental factors. Of the twenty individual factors, rare hand sanitizer use, travel before shift work, and social interactions outside of work increased SARS-CoV-2 transmission. Of the twenty-two environmental factors, only working in air-conditioned spaces was associated with SARS-CoV-2 transmission. Communication messages may enhance workers' individual responsibility and responsibility for the safety of others to reduce SARS-CoV-2 transmission.

ABSTRACT

Relevance: SARS-CoV-2 (Severe acute respiratory syndrome-related coronavirus 2) is a enveloped single-stranded (+) RNA virus. First identified in late 2019, it causes a dangerous, highly contagious infectious disease, COVID-19. In Kazakhstan, the first case of COVID-19 infection was registered on March 13, 2020. The detection and spread of the emerging respiratory pathogen is accompanied by uncertainty about its key epidemiological, clinical and virological characteristics and, in particular, its ability to spread in the population and virulence (ratio of incidence and severity). However, to date, scientists have established the presence of multiple mutations in translatable and non-translatable regions of the coronavirus genome worldwide. Mutation of the virus genome and the spread of new strains of the virus are still ongoing. Understanding and monitoring the genetic evolution of the virus, its geographic characteristics and stability is particularly important to control the spread of the disease and especially to develop a universal vaccine covering all circulating strains. As with many new respiratory pathogens, the basic epidemiological, clinical parameters of the virus and the dynamics of the outbreak are unknown. Factors influencing the course of COVID-19 and the development of complications, also affecting the disease burden, have also not been studied.

ABSTRACT

Introduction. In COVID-19, in addition to the symptoms of respiratory system damage, gastrointestinal symptoms, hemostasis disorders are observed, leading to the development of thrombosis and venous thromboembolism, which can worsen the course of hemorrhoidal disease and lead to exacerbation and serious complications. Given the complexity of the availability of specialized care in quarantine conditions, the role of outpatient consultation with elements of telemedicine is increasing. The aim of this study is to highlight current data on the course of hemorrhoidal disease in (COVID-19), to assess the impact of quarantine on patients suffering from hemorrhoidal disease, and the role of timely outpatient consultation with telemedicine elements in patient management. Methods. We conducted an observational study in the conditions of the regional diagnostic center in Almaty. The study included all patients with exacerbations of hemorrhoidal disease who applied during quarantine in the period July-October 2020. At the first admission, the patients were divided into 3 categories. The patients who were included in the study were surveyed, the symptoms of hemorrhoidal disease (HDSS) were evaluated. After 10-14 days, all patients were contacted again to assess the symptoms of GB and general health using HDSS questionnaires, respectively, and the responses were compared with the responses received at the first visit. From July 2020 to October 2020, 148 patients answered questionnaires and were identified by category. Results. The analysis showed that a long waiting time for an outpatient appointment with a proctologist prolonged the period of exacerbation and worsened the course of the disease. The use of self-prescribed medications for treatment also led to a negative prognosis, which, in particular, led to deterioration. About 80% of patients noted positive dynamics after outpatient admission. According to our established outpatient appointment, 22 patients from the entire sample were operated on in the first month: 10 of them were transferred from the usual waiting list to the priority one and two were operated on urgently. Conclusion. Questions about the relationship of complications of hemorrhoid disease with COVID-19 remain insufficiently studied and require further research. In the conditions of quarantine, it is necessary to review the organization of specialized proctological care for patients, and the introduction of accessible outpatient consultations with elements of telemedicine.

ABSTRACT

Introduction. It is known that most patients with COVID-19 have a disease of mild to moderate severity and can be treated at home. A potential etiotropic drug in the treatment of such patients is favipiravir. To finally decide on the inclusion of this drug in the international recommendations for the treatment of COVID-19, further studies are needed to assess its effectiveness and safety in patients with COVID-19. The aim of the study was to study the clinical efficacy of favipiravir in the complex therapy of patients with moderate-severity COVID-19 coronavirus infection. Materials and methods. A retrospective analysis of 468 medical records of an inpatient patient with a moderate form of coronavirus infection COVID-19, who were treated at the State Clinical Hospital at the Multi-Specialty Medical Center of the Akimat of Nur-Sultan, the Semey Infectious Diseases Hospital, for the period August-October 2020, was carried out. The experimental (main) group consisted of 40 patients with COVID-19 of moderate severity, who, in addition to standard therapy in accordance with the Clinical Protocol for Diagnosis and Treatment "COVID-19 Coronavirus infection (10th edition with changes from 15.07.2020), were prescribed oral favipiravir at a dose of 1600 mg/12 h on day 1, then 600 mg/12 h on the following days, for a total of 7 days. The comparison group (control group) consisted of 40 patients with moderate CVI who did not receive favipiravir. Descriptive statistics were performed with the calculation of the mean (M) and standard deviation (SD) for quantitative variables;percentages were calculated for qualitative variables. Statistical analysis was performed using Microsoft Excel and IBM SPSS Statistics 20.0. P <0.05 was considered statistically significant. Results and discussion. The present study showed that the early initiation of antiviral therapy with Favipiravir, compared with standard therapy without an antiviral drug, in patients with a moderate form of COVID-19 is associated with a statistically significant clinical improvement and a large percentage of virus elimination from the mucous membranes of the upper respiratory tract according to molecular genetic research. In the group of patients receiving favipiravir, complete remission of the disease with normalization of the main clinical parameters and the absence of complaints for 7 days of hospitalization was significantly more often than in the comparison group. Conclusions. The results obtained showed that Favipiravir is an effective antiviral drug in the complex treatment of COVID-19 coronavirus infection of moderate severity. Early administration of the drug in patients with a moderate form of the disease can prevent the progression of the disease to a more severe condition and the development of complications that require additional medical interventions.

ABSTRACT

Central Asian (CA) countries (Kazakhstan, Kyrgyzstan, Turkmenistan, Tajikistan, Uzbekistan) are assumed to be one of the most attractive tourist destinations since this particular geographical location holds immense potential in tourism products. Due to the COVID-19 pandemic, the flourishing tourism sector of these countries has been immensely affected. The aim of this study is to examine the impact of Central Asian tourists' risk attitudes toward traveling during the COVID-19 pandemic through consideration of sociodemographic characteristics. The research was conducted during January through April 2021 based on a sample of 966 respondents via an online questionnaire. In the survey, risks are divided into four main categories: health, psychological, financial and travel destination. Nominal regression was used to identify the way in which risk perception affected travel intentions during COVID-19 and the research findings indicate that Central Asian tourists' risk perception has done so. Hygiene, disinfection and a reliable health system in destinations (21%) will be leading factors in future travel.

ABSTRACT

Despite the declining hunger in Central Asia, food insecurity remains an important issue due to the dry climate. Taking Kazakhstan, Uzbekistan, Kyrgyzstan, Turkmenistan, and Tajikistan as examples, this study assesses their land-water resources carrying capacity in 1999, 2009, and 2018, on the premise that agricultural water and farmland are spatially matched based on the “buckets effect”, using the ecological footprint and water footprint methods. Results show the following: (1) the total farmland area in Central Asia is sufficient to achieve food self-sufficiency;the available farmland area is 2.45 times that of the farmland required for self-sufficiency in 1999, which decreased to 1.71 times in 2009, but slightly increased to 1.92 times in 2018. Specifically, Kazakhstan maintains a surplus of more than 15 × 106 ha in farmland, while the other 4 countries could not achieve self-sufficiency. (2) The water resources pressure rises;the available agricultural water resource (AAWR) in Central Asia is 3.07 times that of the water demand for agricultural irrigation (WDAI), and 3.06 times that of the water demand for irrigation and environmental purification (WDIEP) in 1999, which decreased to 1.69 times of WDAI and to 1.60 times of WDIEP in 2018. Tajikistan has the highest level of water surplus, followed by Kyrgyzstan and Kazakhstan. Turkmenistan and Uzbekistan do not have enough water to sustain agricultural production. (3) The trend of land-water resources carrying capacity declines in Central Asia. In 1999, 2009, and 2018, the land-water resources could support the population’s food demand in this region when only considering farmland matched with WDAI. However, the population carrying capacity deficit would emerge if we considered the matching farmland with WDIEP.

ABSTRACT

The COVID-19 pandemic has had an overwhelmingly negative effect on the music industry in Kazakhstan. Music events had to close or cancel their performances, rendered unable to operate as usual. This sector has been struggling to cope with the pandemic because of the lack of the government support, digital skills, and difficulties in accessing software to record concerts or perform online. Given the need in the literature for surveys of music industry representatives on the impact of the COVID-19 pandemic in different geographic areas, this study utilised the survey approach. During the period of February-June 2021, we approached 102 representatives of the music industry across Kazakhstan. We have collected data on what impact the COVID-19 pandemic has had on the music industry in Kazakhstan. The results of the survey demonstrate that the music industry stakeholders have lost a significant amount of income due to the COVID-19 pandemic. Our study has several policy implications that could be considered when developing the recovery strategy for the music industry in Kazakhstan. The policy makers need to consider the development of financial schemes to support artists in the time of the pandemic. It would be helpful to create grants to support the creative artists who are particularly struggling from the negative consequences of the COVID-19 pandemic. Our results have demonstrated that it would be necessary to unite academics and musicians in associations that could advise them on the possibilities of obtaining grants and special support from state and independent foundations. © 2021 Academic Educational Forum on International Relations.

ABSTRACT

The data on seroprevalence of anti-SARS-CoV-2 antibodies in Kazakhstani population are non-existent, but are needed for planning of public health interventions targeted to COVID-19 containment. The aim of the study was to estimate the seropositivity of SARS-CoV-2 infection in the Kazakhstani population from 2020 to 2021. We relied on the data obtained from the results from "IN VITRO" laboratories of enzyme-linked immunosorbent assays for class G immunoglobulins (IgG) and class M (IgM) to SARS-CoV-2. The association of COVID-19 seropositivity was assessed in relation to age, gender, and region of residence. Additionally, we related the monitoring of longitudinal seropositivity with COVID-19 statistics obtained from Our World in Data. The total numbers of tests were 68,732 for SARS-CoV-2 IgM and 85,346 for IgG, of which 22% and 63% were positive, respectively. The highest rates of positive anti-SARS-CoV-2 IgM results were seen during July/August 2020. The rate of IgM seropositivity was the lowest on 25 October 2020 (2%). The lowest daily rate of anti-SARS-CoV-2 IgG was 17% (13 December 2020), while the peak of IgG seropositivity was seen on 6 June 2021 (84%). A longitudinal serological study should be envisaged to facilitate understanding of the dynamics of the epidemiological situation and to forecast future scenarios.

ABSTRACT

Objectives. In these trying times due to the global effect of pandemic, what social media accounts do academic libraries in Kazakhstan maintain and how can they improve their social media engagement to continuously connect with their stakeholders? This report provides an overview of the current status of social media engagement of selected academic libraries in Kazakhstan during the COVID-19 crises. This paper will give us a picture about the kinds of online postings shared by these libraries particularly with the use of Facebook. Methods. The top two universities ranked by Independent Quality Assurance Agency (IQAA) were considered in this report to be compared with the only autonomous organization of education in Kazakhstan. The library social media accounts of these three organizations were investigated to review the number of followers, frequency of posting, and its overall social media engagement. Data collected is publicly available to all potential users, followers, or subscribers. Using the post engagement rate (PER) formula introduced by Socialbakers (2013) and adapted by Peñaflor (2018) and Magno (2016), this report identifies and analyzes the average PER Facebook pages maintained by academic libraries. The engagement metrics looked into the number of interactions and the widest reach possible in every post. All three academic libraries investigated maintain a Facebook page. The other account was just created last February 2020. To compare Facebook data during the pandemic times, public information available from June – August 2020 was measured. Results. The social media platforms operated by the academic libraries in Kazakhstan are Facebook, Twitter, Instagram, VK, and YouTube. One of the earliest academic library Facebook accounts established in Kazakhstan started in 2010 with less than 3,000 accumulated followers after ten years. This shows a very slow rise in the number of followers considering an academic population of more than 5, 000 people in 2020. Data revealed that Eurasian National University Library’s Facebook account had a higher PER of 0.83 even if it only debut in 2020 compared to the Facebook page of Nazarbayev University which garnered 0.22 PER. KAZNU Library’s Facebook page had the highest PER of 1.02. Conclusions. Facebook is the most popular social media platform across the globe but it is not the case in Kazakhstan. Library marketing and promotion in Kazakhstan needs to be addressed as public relations is not the primary focus. The utilization of social media as a tool for user engagement is not fully developed. One way to look at it is to consider library staffing and identify their marketing background. The pandemic situation must be the turning point of academic libraries to enhance their reach with their stakeholders. It was a test to know the readiness of the library in terms of online communication and interaction. © J. M. Yap, 2020.

ABSTRACT

Purpose: In the process of building the “Belt and Road” and “Bright Road” community of interests between China and Kazakhstan, this paper proposes the construction of an inland nuclear power plant in Kazakhstan. Considering the uncertainty of investment in nuclear power generation, the authors propose the MGT (Monte-Carlo and Gaussian Radial Basis with Tensor factorization) utility evaluation model to evaluate the risk of investment in nuclear power in Kazakhstan and provide a relevant reference for decision making on inland nuclear investment in Kazakhstan. Design/methodology/approach: Based on real options portfolio combined with a weighted utility function, this study takes into account the uncertainties associated with nuclear power investments through a minimum variance Monte Carlo approach, proposes a noise-enhancing process combined with geometric Brownian motion in solving complex conditions, and incorporates a measure of investment flexibility and strategic value in the investment, and then uses a deep noise reduction encoder to learn the initial values for potential features of cost and investment effectiveness. A Gaussian radial basis function used to construct a weighted utility function for each uncertainty, generate a minimization of the objective function for the tensor decomposition, and then optimize the objective loss function for the tensor decomposition, find the corresponding weights, and perform noise reduction to generalize the nonlinear problem to evaluate the effectiveness of nuclear power investment. Finally, the two dimensions of cost and risk (estimation of investment value and measurement of investment risk) are applied and simulated through actual data in Kazakhstan. Findings: The authors assess the core indicators of Kazakhstan's nuclear power plants throughout their construction and operating cycles, based on data relating to a cluster of nuclear power plants of 10 different technologies. The authors compared it with several popular methods for evaluating the benefits of nuclear power generation and conducted subsequent sensitivity analyses of key indicators. Experimental results on the dataset show that the MGT method outperforms the other four methods and that changes in nuclear investment returns are more sensitive to changes in costs while operating cash flows from nuclear power are certainly an effective way to drive investment reform in inland nuclear power generation in Kazakhstan at current levels of investment costs. Research limitations/implications: Future research could consider exploring other excellent methods to improve the accuracy of the investment prediction further using sparseness and noise interference. Also consider collecting some expert advice and providing more appropriate specific suggestions, which will facilitate the application in practice. Practical implications: The Novel Coronavirus epidemic has plunged the global economy into a deep recession, the tension between China and the US has made the energy cooperation road unusually tortuous, Kazakhstan in Central Asia has natural geographical and resource advantages, so China–Kazakhstan energy cooperation as a new era of opportunity, providing a strong guarantee for China's political and economic stability. The basic idea of building large-scale nuclear power plants in Balkhash and Aktau is put forward, considering the development strategy of building Kazakhstan into a regional international energy base. This work will be a good inspiration for the investment of nuclear generation. Originality/value: This study solves the problem of increasing noise by combining Monte Carlo simulation with geometric Brownian motion under complex conditions, adds the measure of investment flexibility and strategic value, constructs the utility function of noise reduction weight based on Gaussian radial basis function and extends the nonlinear problem to the evaluation of nuclear power investment benefit. © 2022, Emerald Publishing Limited.

ABSTRACT

International trade is an important industry for the national economy of any country. Effective logistics chains are required to implement it. The COVID-19 pandemic has shown the unwillingness of countries and international organizations to take coordinated measures to ensure the smooth movement of goods among countries and their efficient distribution. The lack of research on the transport of goods and their distribution, the operation of transport and the state of the supply chain in a pandemic explained by time constraints and insufficient information. The paper studies the trends in the development of international trade and international transport. The foreign experience in organizing freight transportation and their impact on international trade summarized. The impact of the COVID-19 pandemic on the logistics of distribution of goods and measures to improve them assessed. An assessment was made of the efficiency of logistics and factors affecting the development of international trade and freight transport of the EAEU countries, since these countries are an important trade and logistics intermediary in international trade between Europe and Southeast Asia. According to the results of the study, ways to improve the efficiency of logistics proposed. Logistics factors affect economic growth in different ways in each country. Considering the role of transport and logistics and their contribution to the national economy, it is necessary to take into account the mutual influence of modes of transport on the country's economy, especially in the long term. We have identified a causal relationship between modes of transport, transport infrastructure and economic growth according to the Granger test, which allows us to different developed recommendations when developing short- and long-term transport policies. Evaluation of the effectiveness of the development of logistics and trade in the commodity distribution system in the regions of Kazakhstan using the DEA-analysis method made it possible to classify and rank macroregions, and large urban agglomerations depending on the conditions for the development of logistics systems, the state of transport infrastructure and wholesale trade, freight traffic, investments in logistics, geographical location of regions. The development strategy of these objects determined by the prospects for the development and functioning of logistics and their influence on the spatial location and the efficiency of the functioning of existing logistics distribution centers. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
