Published: March 2024

Objective: To determine the orthopedic dental status of the elderly population of Kazakhstan using clinical and diagnostic determinants.

Methods: The dental status of 708 patients from three institutions in Almaty, Kazakhstan, was recorded using WHO dental questionnaires. The patients were divided into groups according to their age and sex, and modern statistical methods were used to process the data. Through the construction of tables and graphs, calculation of relative values, and assessment of the reliability of the differences in the data, we determined if there were any differences between the groups.

Results: The study revealed that most patients who needed orthopedic dental care were 60 years of age and older. The older the age of patients with registered diagnoses of partial and complete adentia, the greater the need for removable prosthetics. The most common type of orthopedic treatment required for these patients was removable dentures. Analysis of the quantitative relationship between the need for orthopedic dental care and patients’ gender revealed the following patterns: the critical value of Chi-square at the significance level p≤0.0001 was 23.95, the exact Fisher criterion was 0.0000 (p=0.0000), and the calculated Cramer’s V criterion and the conjugacy coefficient showed the relationship between the variables were at the levels of 0.17 and 0.18, respectively.

Conclusions: Owing to the aging population in Kazakhstan, and indeed the world, the problem of medical adaptation and social rehabilitation of older age groups is pertinent, and our findings argue that the introduction of geriatric dental services in Kazakhstan is warranted.

Introduction. The increase in the number of patients with autism spectrum disorders around the world leads to the need for public of its symptoms, for early detection and comprehensive care. The increase of public health literacy allows to improve and ease perception of population, families with ASD people. The purpose of the study is to understand the population's perceptions of ASD in Kazakhstan.
 Methods. A developed questionnaire in Kazakh and Russian languages was contributed among population of all regions of Kazakhstan during the first half of 2023. Survey provided using the online Google platform. 410 respondents attended the survey. Statistical analyses were performed using the SPSS13.
 Results. The questionnaire was developed using simulation situations, where the respondent chose the most suitable answer. It was found that the willingness to fully accept a child with ASD is not at a high level, regardless of residence (urban, rural). Fear and curiosity were noted as a high response among the population when simulating the situation of a child with ASD on the street. Despite a high level of willingness to help families, respondents identified gaps in knowledge or methods of helping children with ASD. It is known that children with ASD, depending on the severity of the condition, can study at school along with neurotypical children. There was a reluctance among the population to attend schools with neurotypical children, develop friendships, and even live in their neighborhoods.
 Conclusion. Changes in legislative acts, the development of Roadmaps for children with disabilities are only the tip of the iceberg in the formation of tolerance for people with disabilities. The creation of a host society should be a key factor in the organizations involved in shaping public opinion. Considering that this issue concerns all structures and areas, not only social programs, it is necessary to develop activities for various segments of the population on awareness and training in helping families with ASD.

The persistent and diverse manifestations of post-COVID syndrome present a significant challenge for global healthcare. Beyond the acute phase of infection, individuals continue to grapple with lingering symptoms affecting various organ systems, including the respiratory, cardiovascular, neurological, and endocrine systems. In the respiratory realm, symptoms such as cough, dyspnea, and fatigue endure, particularly in those with a history of severe COVID-19. The cardiovascular impact manifests as chest pain, arrhythmias, and heightened risks of thromboembolic events, emphasizing the intricate connection between COVID-19 and cardiovascular complications. Neurological complications, ranging from headaches to more severe disorders, further contribute to the complex sequelae of post-COVID syndrome. Additionally, disruptions in the endocrine system, including new-onset diabetes and thyroid abnormalities, pose long-term challenges for affected individuals. The review discusses the clinical management challenges posed by the multifaceted nature of post-COVID complications and the necessity for tailored multidisciplinary approaches. A holistic and compassionate response to the long-term effects of COVID-19 requires collaboration across healthcare professionals, researchers and the broader community. By navigating these challenges collectively, we can pave the way for a more comprehensive and effective approach to post-COVID care.

Authors: Okorafor Ugochi Chinenye , Okorafor Uchechi Chioma
Published: March 2024

Background: Monogenic hypertension syndromes result from a single genetic mutation and present with severe, refractory hypertension, distinct laboratory abnormalities, and a positive family history. These syndromes are often unrecognized or misdiagnosed as essential hypertension, thus preventing proper treatment. The rise of molecular genetics has brought these conditions to the limelight, and physicians must be kept abreast of the latest in this field. This paper aims to educate doctors to recognize and institute appropriate management early to prevent end-organ damage.

Discussion: These syndromes all affect sodium transport in the distal nephron of the kidneys. However, they are divided based on the location of the primary disorder, i.e., the adrenal glands or the distal nephron and discussed in that manner. Tables provide an overview of the different syndromes and provide essential information in a snapshot.

Conclusion: The widespread availability of genetic testing facilities will aid in the earlier diagnosis of these conditions to prevent morbidity.

This study focuses on the epidemiology of glomerular diseases, utilizing registered cases of glomerular diseases in the national electronic health system.

Research Methods: The research involves data from 31,421 patients recorded in the Unified National Electronic Healthcare System database, covering glomerular diseases with ICD-10 codes N01-N08 between 2014 and 2019. Descriptive statistics encompass demographic characteristics, all-cause mortality, prevalence and incidence rates, and comorbidities.

Results: Results reveal a substantial rise in diagnosed cases from 7,756 (2014) to 30,686 (2019), with corresponding all-cause mortality increasing from 254 to 1,025. Also, new cases went up from 4,875 (2014) to 6,320 (2019). Over the period, 51% were women, 49% were men, and 67% were of Kazakh ethnicity. Russian nationality constituted 16%, and other ethnic groups comprised 17%. Diabetes mellitus emerged as the primary comorbidity, associated with 20% of cases.

Conclusion: This is the first descriptive study in Central Asia scrutinizing the epidemiology of patients with glomerular diseases (ICD-10 code N01-N08) using administrative healthcare data in Kazakhstan. The findings indicate an escalation in prevalence and mortality, coupled with a gradual increase in incidence among glomerular disease patients from 2014 to 2019. The study underscores the pivotal role of diabetes mellitus as a predominant comorbidity in this context.
Research on seismic performance of corrugated web rigid structures
Authors: Cao H. , Wang G. , Liu H.
Published: March 2024

Abstract: Corrugated web H-beam refers to a steel beam with a wavy shape along its length, which is extensively utilized in various parts of building structures such as beams, columns, and walls. It serves the purpose of connection and support, while the corrugated or folded design enhances the shear resistance and out-of-plane stiffness of the web to some extent. However, despite their advantages including high strength, stiffness, and lightweight construction, relevant regulations stipulate that these members can only be used in lower-intensity applications or higher-intensity scenarios if specific conditions are met. One crucial condition is that the ratio between the design value of axial force subjected to seismic action and the product of the member's flange section area and steel's tensile strength should not exceed 0.4. In this study, we aim to further investigate the seismic characteristics and applicable intensity of corrugated steel structures under earthquakes through large-scale finite element ABAQUS simulations. We will observe dynamic characteristics and failure modes of corrugated rigid frame structures using elastic-plastic time-history analysis methods as well as examine plastic deformation features of steel beam members under low cyclic loads via hysteretic analysis methods. The findings demonstrate that when properly designed with reasonable beam spans, corrugated web rigid frame structures can still be employed in high-intensity areas above 7 degrees even when subjected to an axial compression ratio up to 0.5.

Authors: Indah Lestari  , Dina Fitria  , Syafriandi Syafriandi  , Admi Salma
Published: March 2024

The C5.0 and CART algorithms are similar in terms of velocity and handling of categorical and numeric type data. However, these two algorithms are differences in terms the CART algorithm is binary and classifies categorical, numerical and continuous response variables resulting in classification and regression decision trees. Meanwhile, the C5.0 algorithm is non-binary and classifies categorical response variables resulting in a classification tree. This research aims to classify the Kaggle’s Stroke Prediction Dataset to find out the variables that most influence the risk of stroke, as well as to compare the results of the classification accuracy of the both algorithms. The results of the study showed that CART algorithm has a higher value of accuracy and precision, but its recall value is lower than C5.0. The accuracy value of each algorithm is 77.9% and 77.5%, presision is 89.5% and 83.2%, recall is 67% and 71.4%. Overrall, it can be concluded that there is no difference in classification between the two algorithm. Beside that, in the CART there were 3 variables that most influence on stroke risk, they are age, BMI, and average blood glucose levels. Meanwhile, in C5.0 only 2 variable that most influence, there are age and average blood glucose levels.
DISCOVERY OF A NEW MORPHOLOGICAL FEATURE IN FORENSIC MEDICINE DURING THE STUDY OF GUNSHOT INJURY USING THREE-DIMENSIONAL MODELING OF THE WOUND CHANNEL
Authors: Zmievska Yuliia , Savka Ivan
Published: March 2024

The use of spatial three-dimensional modeling of the main elements of a gunshot injury plays a significant part in the modern forensic medical examination. It allows not only to improve the visualization of such bodily injuries, to increase the objectivity and validity of expert conclusions, to accumulate an evidence basis for war crimes committed with the use of various types of firearms, but it also helps to discover new morphological features which couldn’t be detected when using traditional research methods. The work shows the process of detecting a new morphological feature during three-dimensional modeling of the wound channel caused by the IJ 70-01 pistol loaded with 9 mm cartridges.

Aim of the work. Demonstration of new possibilities of three-dimensional spatial modeling in the process of the forensic investigation of a gunshot wound.

Materials and methods. To achieve the aim of study, a series of experimental shots were fired from the IJ 70-01 automatic pistol loaded with 9 mm cartridges. To conduct bench ballistic tests according to the US standards – NIJ (National Institute of Justice), HOSDB (Home Office Scientific Development Branch) – standardized ballistic clay Roma Plastilina No.1 was used as the main material that absorbs the energy of the bullet and reproduces all the elements of wound ballistics. It was coated in pig skin with subcutaneous adipose tissue in order to recreate more true-to-life conditions of the gunshot injury. The generated wound channel was filled with Tropicalgin alginate impression material (Zhermack, Italy), which was mixed according to the manufacturer’s instructions; it has short setting time and reproduces the smallest details of the wound channel. Thereafter, the formed cast of the wound channel was subjected to a series of photographs at the appropriate angles and its 3D model was created with the help of the graphic design software “Agisoft PhotoScan” and “3ds max”.

Results. The result of the conducted studies was obtaining a spatial three-dimensional model of the gunshot wound channel, which brings about new opportunities for its research. The implementation of three-dimensional modeling techniques made it possible to discover a new morphological feature – a helical torsion of the wound channel, the direction of which can indicate specific design features of the firearm used.

Conclusions. The implementation of three-dimensional spatial modeling in the process of a gunshot trauma investigation sets conditions for increasing visibility and objectivity during conduction of such forensic medical examinations. At the same time, new opportunities are brought about for taking linear dimensions of the existing morphological features of the wound channel main elements with extended precision, the accumulation of demonstrative evidence basis in cases of such injuries, and the discovery of new morphological features for identification of the specific design features of the firearm used.

The life and work of Dr. Bhimrao Ambedkar, a prominent Buddhist activist and scholar, have not only left behind a lasting legacy of ideas and access to social justice for the Indian people, but also served as a source of inspiration for citizens across the globe. Regrettably, many young Indonesians, particularly those in the Buddhist community, are unfamiliar with his life story. Consequently, this study seeks to describe the use of a short biographical animation video about Ambedkar's life in the Religious Studies curriculum at Kertarajasa Buddhist College (STAB Kertarajasa). This short biographical animation video will be employed as a teaching tool to explore topics related to religious diversity around the world and the role of religion as a driving force for social change. Through this case study, the objective of this lesson is to enhance students' understanding of the various expressions of religion worldwide, with a particular emphasis on Hinduism and Buddhism in India. Additionally, Ambedkar's powerful vision for achieving social justice provides guidance for prospective teachers in cultivating a critical mindset. The ability to think critically is crucial for aspiring educators, as they must be proactive agents of change. By fostering a critical mindset, these prospective teachers will be better equipped to embrace change and develop innovative and creative solutions. This paper outlines a learning best practice that utilizes a case study of Ambedkar's life struggle as a means of promoting social equality, religious freedom, and critical education for student-teachers at a Buddhist college through digital storytelling.

Key words: Ambedkar, Buddhism, Philosphy of Education,  Religious Studies, Religious Dialog, Social Justice.

Abstract: The practice of buying and selling potato plants with this conditional agreement by using mutual trust and cooperation to carry out planting In this kind of cooperation, after the harvest, farmers are required to sell all of their potato yields to collectors or investors, not to other parties, and the selling price of the potatoes is determined by the financier. Therefore, the yields sold by farmers to collectors will be deducted to replace the seed prices given by investors to farmers at the beginning of the agreement. Therefore, the writer is interested in researching this problem. The focus of the first problem is: How is the practice of buying and selling potato plants with conditional agreements, and what is the perspective of Islamic law regarding buying and selling potato plants with conditional agreements in Siremeng Village, Pulosari District, Pemalang Regency.

The type of research used is field research, namely research by looking for data sources directly at the place that is the object of research. Primary data was obtained through interviews between researchers, collectors, and several farmers in Siremeng Village, and secondary data was taken from reference literature in the form of books, journals, research results, and other materials related to the problem under study. This research approach uses sociological normative methods, while data collection techniques use observation, documentation, and interviews. Then the writer analyzes the data using the inductive method.

The results of this study are inseparable from the conditional contract, so in terms of the benefit of these conditions and the fact that the pillars and conditions of sale and purchase are generally fulfilled, the sale and purchase are legally valid. by paying attention to all aspects of muamalah. However, these conditions do not affect buying and selling transactions. So the sale and purchase transaction is considered valid even though a condition cannot be fulfilled.

Justification of acid composition concentration reducing in bottom-hole zone treatments at injection wells from 12 to 8%
Authors: Kitel Aleksei Vital'evich , Khaliullov Ildar Ryashitovich
Published: March 2024

The substantiation of the application of a new technology for treatment of bottom-hole zone (hereinafter referred to as BHZ) treatment of injection wells with reduced concentration of acid compositions. Maintaining reservoir pressure during field development is carried out by injecting water into the formation in the bottom hole-zone through injection wells, as a result of which, over time, the filtration characteristics of the formation in the near-wellbore zone deteriorate. In order to clean the bottom-hole zone and, as a result, increase the pick-up rate of injection wells, acid stimulation is performed. The article is based on the world experience of treatment of injection wells using 12% acid composition, as well as on the technology of treatment of bottom-hole zones of injection wells of the Northern Caspian fields with 8% acid compositions. Bottom-hole zone treatment technology is applied at all stages of oil field (deposit) development. Bottom-hole zone treatments are carried out based on actual injectivity indicators and/or after geological and technical measures have been taken at the reservoir. LUKOIL-Nizhnevolzhskneft facilities traditionally use 12% acid compositions for treatment of terrigenous reservoirs, which are selected based on the results of laboratory tests for the current reservoir conditions. The BHZ technology includes sequential treatment of bottom-hole zone and down-hole equipment deposits with hydrocarbon solvent, surfactant solution and acid composition. At that, the technology of work execution (sequence, injection speed, quantity of reagents, number of packs, etc.) is determined by specialists depending on the composition and layout of down-hole equipment, physical and chemical characteristics of the formation (thickness, porosity, permeability, bottom-hole temperature, formation pressure, rock composition) and economic evaluation. The article focuses on the principles, technologies and compositions of solutions used in the North Caspian fields.
Lithological and facies model of the Baku deposits of the Astrakhan Caspian Sea
Authors: Konnov Dmitry Andreevich
Published: March 2024

The influence of fluctuations in the Caspian Sea level on the lithological and facies characteristics of sedimentary deposits is analyzed. Special attention is paid to the study of periodic changes in the water level in the Caspian Sea during the Absheron and Baku time in order to determine the effect of fluctuations on sedimentation processes. The Turanian regression was considered, and its differentiation with the Absheron and Baku transgressions was carried out. The study included the study of climatic conditions of past eras and their impact on the diversity of flora and fauna, which, in turn, had an impact on sedimentation processes in various periods of the Baku stage. Geological and statistical methods were used to determine the characteristics of reservoirs in sediments, as well as to study their distribution over the territory. A lithological and facies model has been constructed that reflects two cycles of regression and transgression characteristic of the deposits of the Baku time, which made it possible to describe the distribution of sandy and clay facies in various sections of the section and interpret a map of sandiness to identify buried river valleys. It is concluded that two lithofacies bundles reflecting the transgressive-regressive cycle of the Great Caspian Sea were identified in Baku time. Hypotheses have been formed according to which the reservoirs were formed in the final stage of the Turkic regression and were later covered with sediments of the Baku transgression. It has been established that these reservoirs play a significant role for gas accumulations and are distributed almost throughout the territory of the Astrakhan Caspian Sea. The identification of areas with a high reservoir content may be important for future exploration in this region.

Published: March 2024

The article is devoted to the problem of waterlogging of borehole products during the extraction of hydrocarbon raw materials, which arises for various reasons. This may be due to the geological structure of the field, non-compliance with the operating modes of wells, poor-quality cementing of backwater spaces, etc. Waterlogging leads to undesirable consequences: reduction of oil and gas production and occurrence of emergency situations. The problems of waterlogging of borehole products are solved using various methods: the use of chemical reagents to reduce the viscosity of water, the use of technical solutions for separating oil and water, repair and insulation works, etc. The Demyansk oil field is considered: its geological features, geological exploration, the main indicators of well operation. The analysis of the dynamics of well flooding and a comparison of the design and actual indicators of the development of the Demyanovskoye field as of 01.01.2017 are presented. The actual dynamics of well flooding is also presented, the reasons for the rapid flooding of the production of wells of the Demyanovsky place of birth are considered. As a result of the analysis of the actual data obtained during the operation of the field, it was established that the main reason for the rapid flooding of the reservoir production of the field is the transfer of wells to a mechanized method of operation, which, in turn, leads to an increase in depression on the formation. It is concluded that the forecast indicators of well flooding calculated on the hydrodynamic model differ significantly from the real ones, and attention is also drawn to the need to select the optimal depression when transferring wells to a mechanized production method to prevent rapid product flooding.

The production of biohydrogen from food waste (FW) by dark fermentation (DF) is a promising technology for commercialisation, as it is both a clean fuel and a suitable means of sustainable waste management. The described experiments compared the biohydrogen production yields obtained after the use of inoculum from two different sources: digested sludge from the wastewater treatment plant (WWTP) in Lodz and sludge from the anaerobic treatment of dairy industry wastewater (DIW) (unconcentrated and double-concentrated). In addition, the effect of different temperatures (70, 90 and 121°C) of inoculum pretreatment on the biohydrogen production in DF was tested. The process was carried out batchwise at 37°C. The highest yield of hydrogen production was obtained after the inoculum pretreatment at 70°C. In addition, a higher amount of hydrogen could be obtained by using sludge from the WWTP as the inoculum (96 cm3 H2/gTVSFW) than unthickened sludge from the DIW (85 cm 3 H 2/g TVSFW). However, after thickening the sludge from the dairy industry, and at the same time balancing the dry matter of both sludges, the hydrogen production potential was comparable for bothsludges (for the WWTP sludge – 96 and for the DIW sludge – 93 cm 3 H 2/g TVSFW). The kinetics of hydrogen production was described by modified Gompertz equation, which showed a good fit (determination coefficient R2 between 0.909 and 0.999) to the experimental data.
The Andean zinc rush: Green extractivism and climate vulnerabilities in the Peruvian highland waterscapes
Authors: Heikkinen Anna
Published: March 2024

Zinc is a green mineral that is increasingly required for manufacturing low-carbon technology. This demand has been promoted mainly by the Global North-led green policies to mitigate the impacts of climate change. However, simultaneously expanding zinc mining risks further entrenching climate threats in fragile socio-ecological environments such as the Peruvian highlands. This article analyses the linkages between the accelerated green extractivism of zinc and its associated climate-related vulnerabilities in the Cunas watershed in the Central highlands of Peru. The study draws on ethnographic-oriented fieldwork in the area in 2019, and 2022 and a review of policy documents on climate mitigation and zinc mining in Peru. The analysis particularly focuses on the recently reopened Azulcocha zinc mine and its intertwined socio-ecological effects on the local waterscapes amid climate change. The analysis draws the theoretical approaches of the political ecology of green extractivism and vulnerability to disentangle the multi-scalar power dynamics embedded in the global low-carbon transition and green extractivism and how these shape climate-related vulnerabilities. The study shows that with the impacts of climate change, accelerated extractivism risks (re)producing multiple vulnerabilities in the Andean highland communities. The findings highlight the urgent need to rethink the global climate proposals in such a way that they do not deepen climate damage in the already marginalized waterscapes in the Andes and elsewhere in the Global South.

The Calculation of the maximum wavelength (?m) of radiation emitted by a black body can be determined from the Wien displacement law, which states the ratio between the Wien constant and the absolute temperature (T). Wien's displacement law can be derived analytically from the Energy Density equation (U?) in Plank's law. The solution for U? is obtained by calculating the first derivative of the function with respect to ? or dU?/d?, and then proceeding with finding a solution to the equation for the derivative. The solution of dU?/d? is the value of ? that makes dU?/d? equal to zero. The resulting wavelength is the maximum wavelength ?m, which is the wavelength value that makes the value in the equation U? the maximum value. The final result of this calculation is the Wien’s displacement law, namely the multiplication of ?m with T equals the Wien constant. So basically, the derivation of Wien's displacement law is to find the maximum value of the function f(x). The maximum value of the function f(x) can be done numerically. Solving numerically can be done with the Modified Newton-Rapshon method. The modified Newton-Rapshon method is usually implemented in the form of computer program code. In this research, the results of the calculation of the maximum wavelength ?m analytically are very close to the results of numerical calculations (modified NR). This can be seen from the results of linear regression with gradient values (m), regression constants (c) and coefficient of determination (R2) close to the ideal values of 1, 0 and 1, respectively.

Hotspots, indicating active fires and potential sources of air pollution, are a major concern due to their impact on air quality in West Kalimantan. In this study, an analysis was carried out regarding the relationship of hotspots to the Air Pollution Standard Index (ISPU) based on the carbon monoxide (CO) parameter. This study aimed to determine the relationship between forest fires and air pollution levels. The data used in this study is in the form of monthly average CO concentration data and coordinates of hotspots in 2017-2021. To determine the effect of CO concentration, CO concentration was converted into ISPU and then mapped using the Inverse Distance Weighting (IDW) interpolation method. In addition, the overlay technique is also applied to the map and the correlation coefficient calculation between ISPU data and hotspot data. The study results show that the annual average number of hotspots ranges from 769 to 3,612, while the average ISPU ranges from 22.21 to 59.03. The highest average number of hotspots occurred in 2019, with 3,612 hotspots and the highest average ISPU value of 59.03, categorized as moderate. However, when examined monthly, the highest average number of hotspots is observed in August and September, with 8,505 and 8,321 hotspots, respectively, and average ISPU values of 55.36 and 88.32, categorized as moderate. Furthermore, the correlation coefficient between the average number of hotspots and the average ISPU per month is 0.91, and per year is 0.98, indicating a very high relationship. Spatially, clustered hotspot locations correspond to higher ISPU values. This implies that as the number of hotspots increases, the ISPU value based on CO concentration increases.

Kota Pontianak merupakan sebuah kota yang berada di daerah aliran sungai (DAS) Kapuas. Kondisi geografis tersebut mengakibatkan Kota Pontianak kerap kali mengalami banjir dan genangan ketika curah hujan tinggi. Salah satu faktor yang mempengaruhi banjir adalah kapasitas infiltrasi tanah. Penelitian ini bertujuan untuk memetakan laju infiltrasi tanah di wilayah Kota Pontianak sebagai proses mitigasi kejadian banjir. Pengukuran infiltrasi dilakukan dengan menggunakan infiltrometer cincin tunggal sederhana dan untuk pemetaan digunakan metode interpolasi kriging. Hasil pemetaan dan validasi dengan data-data sekunder yang ada dapat menunjukkan bahwa daerah di sebelah utara dan timur lokasi penelitian memiliki laju infiltrasi yang rendah. Hal ini disebabkan wilayah tersebut didominasi oleh endapan lempung yang cenderung bersifat kedap air.
