Published: September 2024

In recent decades, a different frequency of dry years has been observed in the Nura River basin in Central Kazakhstan. This article examines the trend of changes in temperature fluctuations over a long period using materials from a separate climate element from the Besoba and Karaganda meteorological stations located in the Nura River basin and the Arkalyk meteorological station located outside the basin, to the west of it, but characterized by similar natural conditions. In the course of research over an 81-year time interval from 1939 to 2019, the absolute and relative frequency of average monthly air temperatures in July in the Nura River basin were established. The meteorological stations under consideration are part of the global international network of meteorological data of Kazhydromet and have constant, accurate series of values of meteorological indicators. Based on the use of the method of statistical analysis, an assessment of the spatio-temporal fluctuations of the temperature regime over a long-term period in the Nura River basin was identified. The study expressed the formation of an arid climate associated with an increase in the average monthly air temperature in the basin of the study area.

Aim. To improve the prognosis of the course of acute bronchitis based on the study of the etiological factor, clinical and anamnestic and laboratory and instrumental characteristics of acute bronchitis in children infected with chlamydia.
Materials and methods. 73 children with acute obstructive bronchitis (AOB) were studied, including 32 children with AOB infected with chlamydia and 41 children with AOB not infected with intracellular infection (ICI).
Results. For patients with AOB infected with chlamydia, in comparison with non-infected patients, the presence of febrile fever, intoxication syndrome, absence of expiratory shortness of breath and whistling wheezes, as well as a longer duration of treatment (more than 10 days) are characteristic. In patients infected with chlamydia compared to the norm, there is an increase in the number of T- and B-lymphocytes, which is manifested by an increase in the absolute number of CD3, CD8, CD25, CD4, CD22, the relative content of CD8, CD4, CD16 and CD22, as well as the level of serum IgA, IgG and IgM on against the background of suppression of innate immunity in the form of a decrease in the absorbing function of phagocytes, phagocytosis, phagocytic number and their digestive function; spontaneous and stimulated HST-test, the index of activity of stimulated neutrophils and the level of lysosomal-cationic proteins. That is, the child's immune system in conditions of persistence of ICI is in the mode of overload and imbalance. In patients with chlamydia infection, compared to patients without infection, in relation to T-lymphocytes, the following were found: higher values of the absolute number of CD3, CD4, CD8 and the relative number of CD3, as well as lower values of the absolute number of CD4, CD16, CD25 and the relative content of CD16; relative to B-lymphocytes: higher values of the relative amount of CD22, the level of serum IgA and a low level of IgG in the blood serum; in relation to indicators of innate immunity: a higher value of the phagocytic number, spontaneous HCT test and low values of phagocytosis, phagocytic index; relative to the non-specific humoral link of immunity – a higher level of CIC with 3.5% PEG.
Conclusions. The revealed reliable differences in clinical and immunological indicators between groups of patients with AOB, depending on the presence of chlamydia infection, provide a basis for their use for diagnostic purposes as a supplement to traditional, protocol methods of diagnosis.

Published: September 2024

The accurate determination of reservoir lithology remains a challenge in petroleum engineering. There are some conventional techniques available to determine the lithology. However, the application of those techniques has been long and complex. So, the main goal of this study is to simplify the identification of reservoir lithology. This paper presents a Pattern Recognition Approach (PRA) to identify the reservoir lithology simply and accurately. It is type of artificial neural network. Four wells from the Camaal Field were chosen to develop this approach. Around 32400 data points from the previous wells were digitized. The PRA approach used depth, gamma ray, lithology, sonic, neutron, and density logs as inputs. The model classifies lithology into permeable and impermeable rocks, further categorizing them into clastic and carbonate rocks, and subsequently into specific types into sand, sandstone, dolomite and limestone. The results show that the proposed approach provides a suitable prediction of lithology with higher accuracy compared with actual lithology. The model demonstrates high accuracy rates in identifying various lithologies, with overall accuracies of 76.2% for permeable/impermeable rocks, 94.9 for clastic/carbonate rocks, 86.2% for sand/sandstone, and 92.8% for dolomite/limestone.

Authors: Ameliawati Hertya Dwi , Hendranastiti Nur Dhani
Published: September 2024

This research aims to investigate the influence of Environmental, Social, and Governance (ESG) on firm performance, measured by Return on Equity (ROE). Additionally, the study explores the moderating role of CEO turnover in the relationship between ESG and firm performance in publicly listed companies on the Indonesia Stock Exchange, with a sample of 33 companies from 2016 to 2022. The GMM estimator method is employed to address endogeneity issues, ensuring consistent and unbiased estimation results. Findings indicate that overall ESG performance significantly affects firm performance, emphasizing the importance of implementing ESG principles in Indonesian businesses to enhance ROE. Other results reveal the pure moderating role of CEO turnover, weakening the relationship between ESG and firm performance. Therefore, proper planning and guidelines for CEO succession are crucial for improving firm performance and sustainability. The research results carry important implications for Indonesian companies to consider ESG implementation in their business strategies. Furthermore, CEO succession planning management is key to maximizing the positive impact of ESG on firm performance. This study contributes to a deeper understanding of how ESG factors influence firm performance in the Indonesian business context, highlighting the significance of executive leadership in managing these impacts.

Published: September 2024

Taxonomic diversity and quantitative distribution of cultured forms of Fe-and Mn-oxidizing microorganisms in Fe-Mn nodules of different sizes and fine earth of Gleyic Luvisols formed in the territory not affected by direct anthropogenic impact, were analyzed. The results were obtained using a combination of microbiological, molecular and analytical methods and noninvasive techniques. Most of the microorganisms which were cultured from the nodules were Mn oxidizers. Bacteria of the genera Bacillus, Rhodococcus, Lysinibacillus, Pseudomonas, and Priestia were identified in the nodules. Quantitative distribution of Fe-and Mn-oxidizing microorganisms in the outer and inner zones of the nodules of different sizes demonstrated that Mn-oxidizing microorganisms were involved in all stages of nodules formation and development, while Fe-oxidizing microorganisms participated in the initial phase of their formation. Spherules and porous structures of bacterial nature were observed in the studied nodules. The host fine earth was characterized by differences in the relative abundance of the dominant microbial groups in the profile. Manganese-oxidizing bacteria were represented in the soil fine earth by the genera Prestia and Methylobacterium.

Published: September 2024

DPA membranes from Allochromatium vinosum cells, in which carotenoid biosynthesis was inhibited using diphenylamine (DPA) were obtained, into which rhodopin was incorporated. The LH2 complex with rhodopin content of 85% was isolated. Using a test for the thermal stability of LH2 complexes (DPA and with incorporated rhodopin), it was established that carotenoids of the early stages of biosynthesis (≤1 molecules per complex) did not interfere with rhodopin incorporation. It was found that when the LH2 complex with incorporated rhodopin was irradiated with light at the wavelength of 502 nm, BChl850 was photobleached at a rate close to that in the control LH2 complex. This indicates that rhodopin, after being incorporated into the DPA LH2 complex, is capable of generating singlet oxygen under illumination. Previously obtained data on heterogeneity of the carotenoid composition in DPA LH2 complexes (variation in the number of individual carotenoids molecules per complex in the general population) and our earlier suggestion about the structural role of carotenoids, namely, their ability to stabilize the LH2 complexes, were confirmed. Based on analysis of our results, as well as of the literature data, the interaction of singlet oxygen and carotenoids is discussed.

Microorganisms capable of degrading hydrocarbons are regular components of natural microbial communities and play an important role in self-purification of marine environments from oil contamination. High-throughput sequencing of the 16S rRNA gene V4 variable region was used to analyze microbial communities of the Barents and Pechora seas and of the microcosms with a spectrum of hydrocarbon substrates: oil, n-nonane, n-undecane, and phenanthrene. The Barents Sea communities of hydrocarbon-oxidizing microorganisms were characterized by predominance of the genera Pseudoalteromonas, Pseudomonas, Porticoccus, and Oleispira, while those of the Pechora Sea contained members of the genera Rhodococcus, Dietzia, Sphingorhabdus, and Hyphomonas. Pure cultures of these microorganisms were shown to utilize the major oil hydrocarbons: n-alkanes, cycloalkanes, and aromatic compounds.
Effect of Substituting of Amino Acids Residues Ser-911 and Thr-912 in the Plasma Membrane H+-ATPase of Yeast Saccharomyces cerevisiae on Its Activity and Distribution of Polyphosphates
Authors: Tomashevsky A. A. , Petrov V. V.
Published: September 2024

The vital enzyme of yeast metabolism, plasma membrane H+-ATPase (PMA1), is phosphorylated during folding and functioning. The main phosphorylation sites are Ser911 and Thr-912 in the C-terminal regulatory domain. The work used wild and mutant forms of the enzyme with substitutions of these amino acid residues with Ala or Asp to determine their role in the functioning of the ATPase and the distribution of polyphosphates (polyP) by fractions. Growth parameters, ATP content, and in situ polyP distribution were determined on whole cells. To determine the ATPase activity in vitro, plasma membranes containing wild-type enzyme and mutant forms were isolated. Mutants S911D, T912D and S911D/T912A had ATPase activity close to the wild type; mutant S911A had increased activity. The growth rate of strains S911D, T912D and S911D/T912A was 2.0‒3.0 times lower than that of the wild type, and the growth rate of S911A was close to the wild type. Mutations S911D and S911D/T912A caused a decrease in ATP content by 2.0‒2.5 times. All substitutions affected the distribution of polyP by fractions. The effect depended on the chemical nature of the substitution: in the case of replacement with Asp, which changes the type of phosphosite, there was a decrease in the polyR1 fraction and an increase in the polyR2 fraction; when replaced with Ala, which removes phosphosite, the effect was the opposite. The content of the polyP3 fraction increased in all mutants. The data indicate that the residues of Ser911 and Thr-912 are important not only for the normal functioning of the PMA of H+-ATPase, but also for the regulation of phosphorus and energy metabolism.

Published: September 2024

Analyzing plant materials is essential for environmental monitoring, analytical control of food products, and medicinal raw materials. A review of global practices has shown that there are still no standard proceedings for chemical sample preparation suitable for all plant types without restrictions on the range of elements determined. Creating a standardized scheme for plants is feasible, as the macro composition of any plants consists of at least 90% organic compounds (cellulose, protein, lipids, etc.), whose mineralization results in the formation of water and a gaseous phase. In this study, certified plant samples were mineralized in a tunnel-type microwave digestion system MultiVIEW (SPC SCIENCE, Canada) with variations in analytical sample sizes, composition and volume of reagents, options for adding the reaction mixture, and vessel heating modes for simultaneous determination of a wide range of elements using inductively coupled plasma atomic emission spectrometry. The completeness of dissolution (the degree of correspondence between found and certified contents) was used as one of the criteria for the optimality of sample preparation conditions. It was shown that with a three-stage heating regime of the vessels (heating rate at the first stage 2.76 оC/min) with a sample weight of 0.5 g and separate sequential addition of the reaction mixture (4 ml HNO3, 1.5 ml H2O2, 1 ml HCl, and 0.05 ml HF), it is possible to reliably determine typical plant contents of Si, Al, Mg, Ca, Fe, Na, K, Ba, Sr, Rb, P, B, Mn, Ti, Ni, V, Cu, Zn.

Authors: Buryakov T. I. , Buryakov I. A.
Published: September 2024

Twenty varieties of fruits (fruits, berries, vegetables) were studied, the presence of trace amounts of which in samples causes false positive signals in explosives detectors based on the ion mobility spectrometry method. These signals are due to the presence of organic acids in the fruits, which effectively form negative ions. The mobilities of some types of these acid ions are close to or coincide with the mobilities of explosive substance ions. Specifically, ions of ascorbic or citric acid, malic acid, tartaric acid, adduct anions of oxalic and malic acids, adduct anions of citric and malic acids are identified by the detector as ions of 2,4-dinitrotoluene, 1,2,3-trinitroxypropane, octogen, and 2,4,6-trinitrotoluene, adduct anions of hexogen and lactic acid, respectively.

At high PT parameters of the cumulates of ultramafic-mafic intrusions at low fO2 (below the QFM buffer), platinum dissolves in the fluid with CO as a carbonyl complex of the native metal. The high solubility of platinum as PtCl2 in brines with NaCl, which is associated with the formation of low-sulfide PGE deposits, is achieved at high oxygen fugacity (above the NNO buffer). It is assumed that at low oxygen fugacity in the low water CO–CO2 fluid, native Pt can also be converted into a cation-soluble form by chlorination. Experimental data (Р = 200 MPa, Т = 950oC, fO2 QFM and fluid CO–CO2) on the reaction of NaCl with magnetite and chromite, accessor minerals of mafic-ultramafic intrusions, with the formation of iron and chromium chlorides are presented. As shown by thermodynamic calculations, the equilibrium in the FeCl3–FeCl2 pair provides the high chlorine fugacity (fCl2). This fugacity is only 3–4 orders of magnitude lower than fCl2 in the Pt–PtCl2 equilibrium and 2.5–3 orders of magnitude higher than in the aqueous fluid 1 M HCl at the same P–T–fO2 parameters.

Published: September 2024

The geophysical effects of a strong seismic event in the form of two earthquakes of magnitude 6.8 and 4.9 that occurred on September 08, 2023 in Morocco at close times 22:11 and 22:30 UTC with an epicentral distance between the foci of ~ 4 km are considered. We used data from a number of observatories of the INTERMAGNET network and the results of magnetic registration at the Mikhnevo Geophysical Observatory of IDG RAS. It was shown that in the absence of significant global disturbances of the Earth’s magnetic field, earthquakes were accompanied by a series of three positive bay-shaped geomagnetic variations with maximum amplitudes from ~1 to ~10 nT, following each other after ~60 min. The maxima of the induced magnetic field variations were observed almost synchronously at distances from ~800 to ~10000 km. The delay time of the magnetic effect relative to the main shock of the first earthquake was ~70 min. Taking into account the almost planetary nature and high synchronicity of the magnetic field disturbances caused over a significant range of distances, as well as time delays corresponding in order of magnitude to the travel time of the seismic signal of a distance multiple of the size of the Earth, it is suggested that the magnetic effect of the seismic event in question was caused by a global source, which can serve as an excited geodynamo. The ionospheric effect of the seismic event under consideration is presented in the form of variations of the critical frequency f0F2 calculated from the data of the ground-based sounding station of the del Ebre Observatory.

Published: September 2024

Soils play an important role in maintaining the sustainability of the biosphere, as well as providing food, clothing and the basis for human life on Earth. In the process of irrational land use, soils are often degraded and sometimes completely destroyed. But, inventory of destroyed soils on a systematic basis is still not conducted in any country of the world. In Russia, traditional soil maps do not reflect the destroyed soils either. We have made an attempt to create the first map of the country, which shows soils destroyed as a result of directed anthropogenic impact. The map shows areas where soil cover was destroyed as a result of construction of buildings, structures, roads and railroads, quarries and embankments during mining. The crowdsourcing database OpenStreetMap was used as the main source of information, as well as the results of visual interpretation of disturbed soils using GoogleEarthTM satellite data. The data on disturbed soils were aggregated to soil-geographical sections of the Unified State Register of Soil Resources of Russia (scale 1 : 2500000) (UGRSR). The map is presented in GIS format (shapefile). The map contains information on the area and share of disturbed soils, as well as the type of impact that resulted in disturbance.

Published: September 2024

The study investigates the potential hazard arising from the actions taken by the Japanese government regarding the discharge of technical radioactive water from the Fukushima-1 nuclear power plant storage facilities. The contamination of the South Kuril Fishing Zone (SKFZ), which is one of the most promising fishing areas for the Russian Federation, with radioactive particles, is considered. Based on the modeling of passive markers simulating radioactive contamination, the study analyzes the pathways and mechanisms of pollution transfer into the SKFZ. The research is conducted using altimetric data on geostrophic currents for the period from August 24, 2022, to August 24, 2023. The pollution transfer into the SKFZ is determined by a set of conditions related to the current development regime of the First Kuril Meander and the local vortex system with varying characteristics, both near the discharge site and at the SKFZ border. A seasonal dependence of the speed and quantity of polluted water infiltration toward the Russian Federation’s shores is established. The possibility of rapid pollution advection into the SKFZ within 13 days has been discovered. This speed is due to the entrainment of contamination by the Kuril Meander and its further transport by the mesoscale vortex system to the SKFZ border. The study reveals periodicity in the influx of pollution into the SKFZ. Graphs depicting the distribution of the quantity of “dirty” markers over their release times and the arrival of polluted water at the SKFZ border have been created.

Published: September 2024

Home assistants are essential today, but they typically support only popular languages. Promoting products that enhance underrepresented languages is crucial for preservation. Using a home assistant in one’s native language, such as Catalan, is a significant step toward this goal. Keyword spotting (KWS) and speech recognition are two potential solutions. The lightweight architecture of KWS models is promising for low-powered edge devices in domotic environments. However, there is a lack of resources to train such models, especially for Catalan. This paper presents a solution using forced alignment techniques with speech-to-text models to extract any set of words from any speech resource.

Phase separation is a common mechanism utilized by viruses to achieve replication, host manipulation and virion morphogenesis. The newly defined phylum _Nucleocytoviricota_ encompass ubiquitous and diverse viruses including _Poxviridae,_ the climate-modulating _Emiliania huxleyi_ virus and the previously termed Nucleocytoplasmic large DNA viruses (NCLDV). Cytoplasmic members of this phylum form viral factories but their nature remains unknow. Here we show that these viral factories are formed by phase separation. We demonstrate that mimivirus viral factories are formed by multilayered phase separation using at least two scaffold proteins. We also generate a pipeline to bioinformatically identify putative scaffold proteins in all other _Nucleocytoviricota_ despite major primary sequence variability. Such predictions were based on a conserved molecular grammar governed by electrostatic interactions. Scaffold candidates were validated for the family _Marseilleviridae_ and highlighted a role of H5 as a scaffold protein in poxviruses. Finally, we provide a repertoire of client proteins of the nucleus-like viral factory of mimivirus and demonstrate important sub-compartmentalization of functions including the central dogma. Overall, we reveal a new mechanism for the acquisition of nuclear-like functions entirely based on phase separation and re-classified phylum _Nucleocytoviricota_ viral factories as biomolecular condensates.
Teorie státní suverenity a praxe intervence
Authors: Königová Lucie
Published: September 2024

V posledních letech se suverenita, klíčový pojem vestfálského mezinárodního uspořádání, stala terčem kritiky vycházející jak z oblasti mezinárodních vztahů, tak i z mezinárodního práva. Tradiční koncepci státní suverenity jako danosti, objektivní, neměnné a absolutní skutečnosti, kterou je možné nezaujatě pozorovat a zkoumat, značně zpochybnily postmoderní filozofie i postvestfálská realita. Stať se snaží dokázat, že státní suverenita je v zásadě moderním vynálezem, jehož zásluhou se do pozice dominantního prvku mezinárodní scény dostal a dosud v ní vydržel národní stát. Přehled myšlení o suverenitě, jak se v průběhu staletí postupně vyvíjelo, je jasným svědectvím o tom, že mezi tou kterou koncepcí svrchovanosti a věděním dané doby existuje přímá vazba. K suverenitě by se tedy mělo přistupovat jako k historické a geografické proměnné, jako k sociálnímu a kulturnímu konstruktu, jako k teoretickému námětu i k reálnému výsledku politického diskurzu. Stať se zabývá proměnlivým a citlivým definičním rozhraním mezi státní svrchovaností a intervencí, která se v poslední době stává stále častější otázkou mezinárodněpolitické teorie i praxe. V důsledku humanitárních intervencí 20. století, především pak misí z posledních desetiletí, se rozpoutala velmi živá diskuze o vztahu mezi suverenitou státu a suverenitou jednotlivce, mezi univerzalitou a jedinečností, mezi kulturní a politickou identitou, mezi lidskými právy a právem národů či států, mezi konsenzem a kompromisem. To vše v současnosti výrazně ovlivňuje sféru mezinárodního práva a mezinárodněpolitické praxe. Kritický přehled úspěchů i neúspěchů mezinárodního společenství v oblasti humanitárních intervencí nabízí pohled jak na slibné, tak i rizikové aspekty současného úsilí o nové promýšlení a redefinici suverenity. Vzhledem k tomu, že se konceptualizace státní suverenity i ospravedlňování humanitárně motivovaných intervencí před domácí i celosvětovou veřejností odehrává prostřednictvím jazyka, autorka této stati klade důraz na politiku pojímanou jako konverzaci, pro niž jsou naprosto zásadními a nezbytnými podmínkami pluralita slovníků, respekt ke kulturní diverzitě a celková otevřenost.
Íránská politika na jižním Kavkaze
Authors: Souleimanov Emil
Published: September 2024

Po rozpadu SSSR v roce 1991 se na jižním Kavkaze znovu objevil hráč, jehož role v regionu byla kdysi významná. Írán, pod tlakem vítězného pochodu ruské armády kdysi donucený k ústupu, se po více než 160 letech nepřítomnosti opět dočkal příležitosti uskutečňovat v regionu autonomní politiku a pokusit se - bude-li mu to příhodnou konstelací moci v regionu umožněno - uskutečnit své odvěké strategické záměry. O úspěchu či neúspěchu íránských snah o znovunabytí bývalého vlivu na jižním Kavkaze by měl rozhodovat Ázerbájdžán, a to v širším měřítku, než jaké se zpravidla předpokládá při posuzování problematiky těžby a transportu ázerbájdžánské ropy. Lze říci, že problematika ázerbájdžánsko-íránských vztahů rozhodující měrou předurčila formování zahraničněpolitické agendy islámské republiky v regionu jižního Kavkazu. Politika Íránu vůči Ázerbájdžánské republice je důležitou součástí nové "velké hry" o vliv v Eurasii. Geopoliticky totiž jižní Kavkaz tvoří významné jižní křídlo tohoto mocenského soupeření, a proto strategie i taktiky uplatňované Íránem v zájmu realizace jeho "ázerbájdžánské politiky" budou mít podstatný dopad na celkové výsledky nové "velké hry". Uveřejněná stať je pokusem o analýzu vývoje íránské strategie v regionu jižního Kavkazu od roku 1991 až do současnosti.

Published: September 2024

Currently, any country that wants to develop sustainably, growing wealthy and stronger must adjust its social relations and solve social problems in a fair, equal, and effective manner. For countries oriented towards socialism, the above requirement needs to be better planned and implemented. In the era of strong developing knowledge economy, ensuring socialist orientation in planning and implementing social policies of universities in general and Ho Chi Minh University of Technology, Viet Nam National University Ho Chi Minh City in particular will create strength for Vietnam to participate in the successful process of international integration and globalization. Therefore, the article studies the issue of social policy in two aspects: the theoretical aspect is the general theoretical issues of social policy to ensure the socialist orientation in Vietnam; The application aspect is the social policies planning and implementing at Ho Chi Minh University of Technology, Viet Nam National University Ho Chi Minh City today with the content of inevitability, difficulties, and advantages in the social policies planning and implementing, as well as analyzing and summarizing 4 groups of policies, which need to be well implemented: talents benefits, employment, social services response, support policies for officials, employees, and students with difficult circumstances, based on the needs of learners, jobholders, and employees, thereby listening and absorbing their opinions to make and implement Party-oriented social policies with legality, humanity, and democracy in accordance with the socialist orientation.
The Communist Party of Vietnam applies Ho Chi Minh's ideology on the international integration in the current period
Authors:   Ho Chi Minh City University of Technology, VNUHCM, Vietnam, Phan Huong Thi Thanh
Published: September 2024

From quite early on, President Ho Chi Minh was aware of the meaning and importance of international integration to contribute to the national liberation and development of the country, and preserving peace and stability in the region. According to him, the international integration process aims to bring many advantages to the struggle for the national independence and development. Nowadays, the international integration has become an urgent requirement of each country and ethnic group, and is taking place more and more widely, penetrating deeply into different fields and industries. It can be said that the international integration process affects most countries in the world. If we are alone and separate from this flow of the world, the development of the country can be significantly affected. Therefore, today, strengthening the application of President Ho Chi Minh's views in the current international integration process has a profound meaning. This is one of the extremely important motivations, contributing to promoting Vietnam's diplomatic relations and international integration to new heights, becoming more and more sustainable, deeper, and more effective, especially the international economic integration. For that reason, it is quite necessary to strengthen research on the Communist Party of Vietnam, applying Ho Chi Minh's ideology on the international integration in the current period, helping set guidelines and policies of the Party more closely and effectively.

One of the topics that has been discussed on twitter is the rules regarding the removal of masks. However, there's a chance that the data from Twitter contains unequal data classes. An unequal amount of data can cause the classification process to malfunction. Combining under- and oversampling techniques is known as combine sampling, and it is a data-balancing strategy. The research's data consists of Indonesian tweets using the hashtag "The Policy of Removing Masks." In this study, the classification approach was K-Nearest Neighbor, while the oversampling and undersampling techniques were SMOTE and Tomek Links. The purpose of this research is to classify sentiment using the K-Nearest Neighbor algorithm and to use combine sampling to balance the amount of training data in the two classes that are not yet balanced. 234 training data with a positive sentiment and 652 training data with a negative sentiment were obtained after the data was divided. Due to an imbalance in the quantity of training data between the two classes, the positive class's data is minor and the negative class's data is major. The quantity of training data are 613 in the positive class and 613 in the negative class obtained following the combine sampling. Following the balancing of data between the two classes, sentiment classification was performed, yielding accuracy of 60.4%, precision of 78.5%, and recall of 65%. The reason for the accuracy number of 60.4% is because machine learning misinterpreted a tweet regarding Indonesia's mask removal policy, leading to incorrect classification.

Published: September 2024

Packaged food and beverages often pose a risk of increasing diabetes when consumed regularly. This study aims to classify these products based on their nutritional content listed on the labels, with a focus on identifying diabetes risk. The methods employed include K-Means and Fuzzy C-Means, K-Means is used to determine initial center of cluster, while Fuzzy C-Means enhances the clustering by assigning probabilistic memberships to each data point. These methods are applied to products sold in stores in Banyumas Regency, Central Java, Indonesia. This research is the first to combine these two methods in the context of product clustering based on nutritional labels. The results indicate that packaged food and beverage products can be classified into high-risk and low-risk clusters for diabetes. Consequently, this study provides important guidance for consumers in choosing healthier.
