Enhancing Cybersecurity in Climate Technology Transfer: The Interaction of Environmental Law with Digital Security
Authors: Nasirov Jahongir , Cheng Le
Published: March 2024

The Climate Change Convention, together with developed and developing countries, is taking measures to be more effective in combating climate change with the gear of modern methods and innovations. However, the technology mechanism has launched a series of initiatives aimed at exploring the potential of artificial intelligence to accelerate and scale up groundbreaking climate solutions, both in mitigation and adaptation efforts. To address the research questions, a comprehensive literature review is conducted to identify existing gaps and establish a foundational understanding of the legal and cybersecurity landscape in climate technology transfer. Different countries and organizations may adopt disparate cybersecurity measures, making it challenging to ensure a cohesive and standardized approach to safeguarding climate-related technologies. This fragmentation could result in inefficiencies, confusion, and a lack of interoperability. The urgency for a holistic and adaptive approach at the confluence of environmental law and digital security, the evolution of legal frameworks, the fortification of cybersecurity measures, and the ethical dimensions of technology transfer are integral components of a resilient foundation for a sustainable and secure future in climate technology exchange.

Background and objective: The background of this study revolves around endodontic treatment, which is a therapeutic approach involving the chemical and mechanical disinfection of root canals, followed by the establishment of a secure three-dimensional seal. The primary objective of this research is to investigate and understand the underlying factors that contribute to flare-ups experienced by patients undergoing endodontic treatment. Method: A total of fifty-two patients were considered participants and were included for history taking, clinical examination, radiographic assessment, and data analysis after receiving Root Canal Treatment (RCT) for different types of teeth (incisors, canine, and premolar) by different students (operators) and different supervising seniors (trainers). During this time, the operator performed RCT on various patients, and the participants were followed up after they completed root canal obturation. Statistical analysis was done by the SPSS program, chi-square and Fisher's exact test were used to determine the correlation between variables. Result: The level of significance used in this research is ≤ (0.05), and the result is significant when (p≤0.05). The main findings were that the frequency and distribution of post-instrumentation pain was (30.8%). According to our data, we found out the highest incidence of flare-up in HMU was related to pulp remnant and periapical pathosis. Conclusion: There are several factors that are related to the prevalence of post-obturation flare-up such as over-instrumentation, pulp remnant, periapical condition, presence of patient medical history, and perforation. According to these factors the dentist should be aware of the possibility of flare-up occurrence, however, it must be borne in mind that theories about these factors cannot be completely conclusive. Keywords: Endodontic Treatment, Flare-up, Postoperative pain.

Food insecurity in books for children
Authors: Day Dian
Published: March 2024

Issues of class and poverty are largely absent from children’s fiction and from elementary school curricula, even though, in Canada, one in every five children live in food insecure households. This paper examines the limited number of middle grade children’s books that feature depictions of food insecurity published in North America in English in the past forty years and interrogates their assumptions about children, poverty, food, and hunger. While the primary cause of food insecurity for children is inadequate household income, often due to systemic inequities, most children’s fiction suggests individual choices or life circumstances are to blame and charity, kind strangers, and simple luck are the solutions, giving children, at best, an incomplete understanding of the social and political issues that produce food insecurity.
The framing of food in Canadian university classrooms

Published: March 2024

There are numerous “positivity” movements circulating such as sex positivity and body positivity that affect how sexuality and bodies are discussed, including in educational contexts. These movements have provided alternative discourses that challenge constructions of sexualities and bodies as “dangerous”, aberrant, or “other”. There is potential for “food positivity” to do the same given how food is frequently constructed as “risky”, reflecting anxieties about industrial food production and the impacts of “bad” food on human health, appearance, and the environment. Food practices, and the discourses that support them act as moral signifiers and can be exclusionary, exacerbating marginalization and inequities. Alternatively, food pedagogies can prioritize inclusion, diversity, and sustainable, resilient communities. How might the discourses that circulate in post-secondary food education construct and support positive relationships with food? Two major, and largely silo-ed, fields in Canadian higher education are Nutritional Sciences and Food Studies. Using publicly available syllabi (n=97) from undergraduate courses across Canada, this study investigated how food positivity is being enacted. In Nutritional Sciences, food positivity emphasizes nutritionism ideology whereby the composition and quantity of nutrients can add up to an (undefined) healthy diet. In Food Studies, food positivity is associated with local, equity-promoting, and culturally-sensitive approaches. In both fields, “food negativity” also appears in relation to “obesogenic” foods and systems, revealing an underlying fatphobia. Greater transdisciplinary collaboration with Fat Studies would benefit both fields in enacting a broader and more inclusive food positivity.

This investigation was initiated with the intention of defining the mode of action of the chemical retention agents used, especially with regard to their ionic nature and chain length. The efficiency of these agents is often explained in the literature as being due to their action on the electrical charge on the surface of the various substances present in papermaking suspensions.⁽¹⁻¹²⁾ After numerous laboratory studies carried out in media with well defined ionic strengths and on simple mixtures, we tried to see if a relationship existed between retention and zeta potential for a medium as complex as the papermaking water system. Trials were carried out on the pilot papermachine at the Centre Technique du Papier.
The Measurement of Electrokinetic Effects On a Paper Machine
Authors:   Felix Schoeller Jr., Osnabruck, Germany, Sack H. W.
Published: March 2024

During every minute of operation of a typical paper machine several square kilometers of interface between the solid and liquid phases of the pulp suspension pass down the wire. These interfaces possess a number of special properties. The formation of an electrical double layer on the surface of the solid phase, for instance, influences to a large extent the process of sheet forming, the retention of fibres, fillers and sizing agents and, in turn, the characteristics of the finished sheet. There is understandably, therefore, a strong interest in obtaining measurements of these interfacial characteristics with the intention of optimising the operation of the process and the performance of the products. This interest is demonstrated by the number of publications which have appeared on the subject over the last few years. Melzer,⁽¹⁾ for example, cited as many as 102 papers in 1972 and since then many more have appeared.

The importance of wet-web strength in the manufacture of newsprint is considered. A number of case histories are presented, which illustrate how the assessment of wet-web strength can be effectively used to clarify practical observations on paper machines. These observations were concerned with the influence on paper-machine operation of normal fluctuations in the properties of the mechanical and chemical pulp components of a newsprint furnish. Wet-web strength measurements were carried out at moisture contents of the web which reflect its ability to release water under standard drainage and pressing procedures. A rapid wet-web burst testing technique was developed that is suitable for evaluating wet-web strength in a mill environment.

As a means of access to the more complicated phenomena of wet pressing, we have observed and interpreted compression dewatering in an extensively simplified case. It appeared best to begin with a system characterised by a single spatial co-ordinate; a system containing synthetic fibres which would be non-swelling and nearly identical, filtration-formed into a uniform bed, and mechanically conditioned; a system for which one could expect to find stable and reproducible compressibility and permeability properties. It also appeared that we could construct a theory of the behaviour of such a system, and develop effective numerical procedures by which to obtain the predicted response to rapidly varying applied stress. Experiments and theory were to include conditions in which the increasing stress on the solid portion of the system would induce significant non-uniformity.
Capillary Rise in Porous Media
Authors:   Federal Research Centre for Nutrition, Institute for Process Technology, Karlsruhe, Germany, Schubert H.
Published: March 2024

Capillary rise is one of the most complicated transport phenomena in porous media. So far there has been no theory which can claim to describe it adequately. As for fine powders, adequate experimental data in cases of imbibition do not even exist. Both measuring and evaluation methods have, therefore, been developed by which the most essential parameters can be obtained. Tests on fine powders show that the capillary rise is decisively influenced by dynamic effects. Static capillary pressure-so far regarded as the driving force-can only be decisive at very low transport velocities. The penetration rate of liquid into fine powders is characterised by a dynamic capillary pressure, at least in the initial stages of high velocities. The newly developed theory was tested with fine powders of different substances. The results confirmed the original assumptions. Whether, or to which extent, this theory can also be applied to fibrous materials, remains to be seen from tests still to be carried out.

The porous nature of paper can be regarded as consisting of three components, namely, an external void system, an internal void system and discontinuities. The external void system can be associated with the concept of paper roughness and is totally open in one direction. The internal void system can be regarded as that which can be observed by simple optical microscopy (e.g. paper sections cut at an oblique angle). The discontinuities can be defined as all those phenomena that deprive the voids between fibres of the characteristics which would justify regarding them as capillaries with smooth surfaces. These would include the structural elements of the fibre surface, the fines in paper, the fibrils and the fibril bundles protruding into the interfibre voids, the pits in the fibre surface and pores in the cell walls. The interactions between the components of the model system proposed above have been investigated using thickness, light transmission and water absorption measurements.

Esterification of pulp fibres have been performed in pyridine and toluene. The influence on swelling and the mechanical properties of sheets are shown to be different at the same level of esterification obtained by the two methods. This is interpreted to be due to the topological position of the acetyl group in the cell wall. Thus, esterification in toluene tends to allocate the esterification to the surface while in pyridine the interior of the cell wall is made accessible. At low degree of esterification in pyridine an increase in swelling is obtained. Thus, the hydrophobic groups may be seen as structure-breakers primarily by keeping the carbohydrate chains apart which otherwise would tend to form water-inaccessible regions, due to extensive hydrogen bonding. This maximum in swelling is maintained even in the dry state. Thus, the equilibrium moisture content is higher in a fibre moderately esterified in pyridine than a nontreated fibre. The introduction of acetyl groups is also shown to have an influence on the reswelling of the fibre after drying. The loss in swelling after drying is considerably less after drying for a moderately esterified fibre than for a nontreated fibre. Consequently the retention of the strength of the sheet has been improved. Essentially moderately esterified fibres which have been once dried yield a sheet with a strength equal to never dried virgin fibres. The experiments with the fibres esterified in toluene did not yield the same effect indicating that the presence of hydrophoric groups inside the cell wall is necessary in order to maintain the swelling properties of the fibres. The results indicate new ways of permanenting the strength potential of recycled fibres and have illustrated the fundamental mechanism leading to the decrease of strength potential due to the drying of virgin fibres.

Authors: Quyet Chu Ba , Ha Phung Viet
Published: March 2024

E-commerce has been adopted by businesses and consumers in Vietnam for consumption activities, profit-seeking, buying and selling goods, conducting business, competing, and expanding markets. Businesses have chosen e-commerce due to its benefits, the trend of applying digital technology, and the ongoing modern business environment. Many previous studies have identified factors influencing the acceptance of e-commerce, but only some studies have approached sustainable e-commerce. Developing sustainable e-commerce requires businesses to invest more money and technology in business processes, which consumers may only sometimes accept. This article applies the TOE framework to identify factors influencing the acceptance of sustainable e-commerce by measuring the importance coefficient of these factors. The research results reflect changes in the factors affecting the acceptance of sustainable e-commerce. The study also provides recommendations for stakeholders involved in developing sustainable e-commerce.

Published: March 2024

У доповіді наведено результати дослідження особливостей становлення й розвитку сучасної української нації як етнічно, культурно, мовно та політично багатоскладової громадянської спільноти. Це, зокрема, єдність і боротьба протилежностей особливого етнічного та спільного національно-громадянського в процесі націєтворення, зв'язок цього процесу з біфуркаційними соціальними кризами, що супроводжували суверенізацію України й наступні політичні, світоглядні та інші зміни всередині українського соціуму. Серед причин таких криз — намагання конкурентних груп правлячого класу країни політизувати етнічні відмінності населення різних регіонів для формування й мобілізації «свого електорату», а також гібридна та повномасштабна воєнна агресія Росії і росіян проти України та українців. Проаналізовано концептуальні суперечності законодавства, покликаного спрямовувати державну політику націєтворення й посилення соціальної згуртованості нації та забезпечувати інституціональну ефективність державного етнополітичного менеджменту. Акцентовано увагу на необхідності вдосконалення правових регуляторів цієї політики та управлінських практик. Аргументовано пропозиції щодо такого удосконалення.

Published: March 2024

Various assessment criteria are applied to ensure the sustainability of production sites. These evaluation criteria are based on quantitative indicators and reflect the corrected performance of production areas. Adequate assessment analyses the territorial organisation of production areas, efficient operation, process management, etc. more clearly in the future, and makes it possible to conduct their comparative analysis. One of the methods of such an approach is the cluster. A cluster is a group of objects with similar properties. In English, cluster means bunch, gathering, concentration, and group. From this point of view, the for- mation of the infrastructure organised in connection with the production, which contributes to the increase of competitiveness between the production areas, and the application of an innovative cluster approach are required in this research work. This approach allows the creation of a new product, increases production efficiency, and helps form a sustainable production network. This article presents the analysis of the GDP in Azerbaijan in the period of 1995-2021 carried out taking into account the ratio of the AZN to the US dollar, calculates the volume of GDP per capita, determines the regional trend of economic development, and provides the variability of the dynamics in the fields of the economy in a related manner. Later, all these indicators were summarised, clustering was carried out, coefficient values of quantitative indicators for production areas were determined, and indicators of clustering of production areas for economic regions of Azerbaijan were calculated. Consequentially, the article concludes that the application of the regional cluster approach indicates the potential power of production enterprises, the scale of their activities, economic-geographical relations, etc., which makes it possible to increase regional competitiveness between production areas. Thus, the cluster approach determines competitive advantages related to the organisation and operation of production, stimulates regional development, and can also lead to an increase in revenues to the local budget.
The physical and chemical properties of the technosols in the pot experiment with waste and groundwater irrigation

Published: March 2024

Mediterranean areas are characterized by a strong spatial variability that makes the soil hydrogeological logical response highly complicated. Some seasons provoke dramatic changes in soil properties determining the runoff rates, such as soil water content or soil water repellency. In recent years, important progress has been made in adapting water needs to local conditions through the use of various parameters to assess soil water status. Estimation of the water status of the soil has been widely used in soil science as a tool for quantitative analysis. The main objective of this case study was to analyze technosol and irrigation water physical and chemical properties in the pot experiment with lysimeters. A pot experiment with Avocado rootstocks was equipped with lysimeters in the facilites of the «La Mayora Experimental Field site» of the Higher Council for Scientific Research (Spain). The scheme of the pot experiment included three sources of irrigation: a) groundwater; b) regenerated municipal wastewater (100%); c) a mix of ground and regenerated municipal wastewater (50 / 50%). Chemical analysis data indicate that the reclaimed wastewater does not meet irrigation requirements in terms of pH, EC and due to the significant content of sodium and chlorine. Even groundwater satisfies irrigation water qualitative requirements partially. The suitability of irrigation water on pH level can be characterized mainly as unsuitable and doubtful. Diluting regenerated wastewater with groundwater following the 50% principle led to a decrease in the potential risks for salinization of groundwater connected with leaching of the leachate. The dynamics of the change in the volume of leachate are related to precipitation, the frequency of irrigation, and different manifestations of the physical, mineralogical, and chemical properties of technosols.

Published: March 2024

The purpose of this article is to study the chemical composition of water and the hydrochemical regime of the left-bank tributaries of the Dniester within the Ternopil Oblast at 9 monitoring sites on the Zolota Lypa, Koropets, Strypa, Seret, Nichlava, and Zbruch Rivers. Water quality monitoring data from the State Agency of Water Resources of Ukraine for the period from 1993 to 2020 were used. The hydrographic assessment of the territory following the Water Code of Ukraine showed the presence of two medium-sized rivers (Seret and Zbruch) and four small rivers among the studied rivers. The chemical composition of the water was analyzed by the following groups of components: major ions and water salinity; physicochemical parameters; and biogenic components (nitrogen and phosphorus compounds). It was found that the water of most studied rivers is calcium bicarbonate by hydrochemical type. The water of the Nichlava River is calcium bicarbonate-sulfate. The average annual salinity of the water of the studied rivers varies from 476 mg∙dm-3 to 699 mg∙dm-3. It was determined that the water of most rivers is moderately fresh in terms of mineralization. The water of the Nichlava River is fresh with high mineralization. The hydrochemical regime of rivers is generally related to the hydrological regime. The minimum concentrations of the main ions and salinity values of the studied rivers are observed during the summer-autumn low water mark, which is explained by the significant amount of precipitation and the presence of floods during this period. In winter, the maximums of these indicators are observed. Among the biogenic compounds (ammonium, nitrite, nitrate, phosphate), the clearest manifestation of the hydrochemical regime was recorded for nitrate. The minimum NO3– concentrations are observed in the summer and autumn low-water periods when nitrates are consumed for the development of aquatic plants. In the autumn period, with the death of aquatic plants, nitrates accumulate, and during the winter low water, their maximum average content is observed. The analysis of the monitoring system of the State Agency of Water Resources of Ukraine for the content of the studied components in the water of the left-bank tributaries of the Dniester over a multi-year period for all samples showed that their concentrations were within the regulatory requirements, except for one case. Particularly, in the water of the Nichlava – Borshchiv River, an ammonium concentration of 15 mg∙dm-3 was recorded, which was 7.5 times higher than the standard (August 2, 2000).
Formation of fluvial xenolandscapes of Martian valleys and channels
Authors: Kyryliuk Serhii M.
Published: March 2024

Contemporary concepts of Martian Valley formation and the current state of their study are examined. Three-dimensional modeling was conducted using the examples of two regions on Mars, the Lani Chaos Region and Kasei Vallis, to determine and map the main morphological features typical of Martian valleys as a basis for identifying xenolandscapes. The xenaxiomatic author’s concept was applied as a means of investigating xenolandscape diversity on the surface of Earth-like planets, in this case, Mars. The xenaxiomatic concept is the result of incorporating and utilizing traditional knowledge of the differentiation and application of axioms of cognition. Specialized for xenoplanetological use, this integrative cognitive tool is a variant of an axiomatic approach. The main essence of this approach, in the case of distinguishing xenolandscapes, lies in developing a unified scheme for searching for corresponding xenolandscape elements that are axiomatically elementary fragments of the planet’s surface, followed by their classification and xenolandscape interpretation. Scientific awareness has been achieved by filling it with all available information from various natural sciences related to xenoplanetology and subsequent exploratory xenolandscape interpretation and synthetic cartographic representation of characteristic, typical local xenolandscape formations on Mars (part of the Kasei Vallis valley). These depicted objects are extra-rank, meaning they have not yet been ranked in terms of xenolandscape formations but are uniformly formed due to the synergy of influences and interactions of different forces, yet genetically stemming from the same xenolandscape-forming factors of material and energy-field xenonature. A mechanism for the formation of modern Martian valleys is proposed through the influx of heat flow and impact events. Exploratory xenolandscape studies, with their positions verified by this conducted research in terms of theoretical, methodological, and methodical content, have become an unexpected benchmark for the effectiveness of similar theoretical and methodological components of classical landscape science, with which the research capabilities of landscape science can and should be compared.

Published: March 2024

One of the most pressing problems facing cities, which negatively affects public health. There is a global practice of online monitoring of the content of pollutants in the air of settlements and informing the population about dangerous periods of increased pollution concentrations for certain categories of diseases and the population as a whole. It is also likely that one of the factors of pollution spread is the landscape differentiation of the city’s territory. The purpose of the study presented in this article is to develop statistical and cartographic models of the spatial distribution of air pollutants within the city of Kharkiv and to establish the relationship between the degree of air pollution and types of urban landscapes. Methods. Based on the analysis of the main methodological approaches and tasks of cartographic modeling of the spatial distribution of air pollution, the study substantiates the choice of the modeling method in this study; the features of a large city as an object of cartographic modeling of air pollution are assessed. Results. Based on the results of long-term monitoring by the Kharkiv Regional Center for Hydrometeorology, a statistical analysis of the results of the maximum and average content of pollutants in the atmosphere of Kharkiv was made and the spatial distribution of air pollution in Kharkiv (including (dust, carbon monoxide, nitrogen dioxide, sulfur dioxide, formaldehyde) was modeled, and patterns of pollution distribution were identified according to landscape types. Conclusions. In general, the spatial analysis of pollutant concentrations in the territories of Kharkiv showed that, in terms of maximum concentrations, the southeastern part of Kharkiv is most affected by carbon monoxide, nitrogen dioxide, and formaldehyde. The reason for this is the large area of industrial facilities. The northwestern part of the city has the highest concentrations of dust and sulfur dioxide. There is a lowering of the relief in the floodplain type of landscape and dense development. Intensive traffic and lowered relief (floodplain landscape) cause high average concentrations of dust, carbon monoxide, and sulfur dioxide in the southern part of the city. Nitrogen dioxide concentrations exceed the TLK in the northwest. The reason is the lowering of the relief on the outskirts of the city (floodplain landscape). The central part of the city has a high average concentration of formaldehyde. In general, a pattern of high concentrations of pollutants was found on the floodplains of the Lopan and Kharkiv rivers, with the lowest concentrations confined to watershed types of terrain between the Kharkiv and Lopan rivers and the Udy and Lopan rivers.

The major dyke in the Ranipet district shows WSW-ENE trending dykes intruded the hornblende-biotite gneiss with gabbroic diorite and granite gneiss. The dolerite in this region shows typical dolerite composition with high alteration like chloritization and sericitization. Mineralogically, the rock shows laths of plagioclase, anhedral to euhedral clinopyroxene with basal cleavage, and quartz minerals. The opaque minerals ilmenite and magnetite crystals interstice the major minerals and it has altered boundaries. Texturally, the rock shows subophitic and intermediate gabbroic texture (granular texture). TAS diagram shows that the dykes plot in the basalt, basalt andesitic, and rhyolitic field (highly sericitized dolerite). The host and other associated rocks plot within the sub-alkaline field. The bivariate plot for the studied dolerite shows a positive correlation with SiO2, CaO, Na2O, K2O, and P2O5 and a negative correlation with TiO2, Fe2O, and Al2O3. The AFM and Jensen plots show that the dolerites samples plot in the tholeiitic field with Fe enrichment and a High Fe tholeiitic character respectively. The primitive mantle diagram shows the depletion of Nb, P, and Ti showing possible interaction of crust during the emplacement. The Chondrite normalized plot for the dolerite shows enrichment of LREE and Slight depletion of HREEs indicates OIB character. Tectonically, the dolerites formed emplaced in the continental and alkaline arc OIB settings with E-MORB affinity.

Nagarahal village in the Bilgi taluk of Bagalkot district in Karnataka state shows the contact between the younger Bilgi granites and the Deccan basalts. The thermal impact that has happened on the pre-existing granites by the basalts has been studied by identifying the field occurrence of the contact zone of granites and basalts. The unaffected portion of the granites and the basalts that are far away from the contact are studied as well. The petrographic studies of the contact rocks between the granites and basalts show the polygonal recrystallized quartz with the triple point contact with other grains indicating the decussate texture indicating the high-temperature conditions, crushed quartz grains having contact with each grain appear as sugary crystals from the granoblastic texture, the irregular oriented mafic and felsic crystals show the hornfelsic texture and micrographic, and intergrowth textures showing the effect of thermal metamorphism near to the contact between the granite and basalt. The post-hydrothermal solution activity is at the peripheral region of the contact between granite and basalt which is seen by the formation of tourmaline. The mineral assemblages that are identified by the petrographic studies are muscovite, quartz, orthoclase, sanidine, sillimanite, chlorite, and Fe-Ti oxide minerals. The mineral chemistry data shows the high potash K-feldspar that consists of Or from 84% to 97.97%, Ab2%- 4.26%, and An0.09%-1.34% was identified as sanidine variety of K-feldspar, the plagioclase feldspar shows the dominant composition of Ab ranging from 84.92% to 97.10%, An content in plagioclase was found to be ranging from 0.87% to 14.02%, and the Or content is ranging from 1.06%-7.41%. indicating the presence of the albite variety of plagioclase, the Fe2+ dominating chlorite, and the presence of tourmaline indicates the hydrothermal effects at the periphery of the contact. The two feldspar thermometry indicates the formation temperature was 750°C at the contact and the chlorite formation temperature calculated is found to be 313°C which shows a decrease in the temperature away from the contact of the basalt and the granitic rocks. Whereas the granite and the basalts that are far away from the contact do not show any changes. The mineral assemblages, mineral chemistry data, and thermometric results indicate the high temperature and low-pressure sanidine facies of contact metamorphism in the studied area.

PT XYZ merupakan perusahaan distributor pupuk yang menerapkan penjualan secara tunai dan kredit. Dalam penjualan kredit akan menimbulkan piutang sebagai hasilnya. Tujuan dari penelitian ini adalah untuk menganalisis faktor-faktor yang menyebabkan piutang tak tertagih dan untuk memahami strategi pengendalian internal untuk mengurangi piutang yang tidak tertagih di PT XYZ. Penelitian ini menggunakan metode kualitatif dengan pendekatan deskriptif. Objek dalam penelitian ini yaitu data piutang tak tertagih di PT XYZ selama periode tahun 2020-2022. Jenis data yang digunakan yaitu data primer dan sekunder. Teknik pengumpulan data yang digunakan adalah wawancara dan dokumentasi. Hasil dari penelitian ini menunjukkan bahwa pengendalian internal piutang di PT XYZ belum dilakukan secara efektif. Hal tersebut dilihat dari faktor penyebab meningkatnya piutang tak tertagih, dimana sistem perusahaan yang belum optimal dalam mengelola piutang dan penerimaan, keterbatasan petugas pembukuan dalam melacak penerimaan pembayaran dari pelanggan, dan perusahaan belum melakukan kebijakan penagihan yang jelas dan konsisten dengan menentukan jatuh tempo pembayaran yang jelas serta konsekuensi yang tegas bagi pelanggan yang tidak mematuhi kebijakan pembayaran, serta kurangnya pengawasan internal untuk mengelola piutang perusahaan.

This article presents an analytical comparison between constituency parsing and dependency parsing – two types of parsing used in the field of natural language processing (NLP). The study introduces an algorithm to enhance keyword extraction, employing the noun phrase extraction feature of the parser to filter out unsuitable phrases. This algorithm is implemented using three different parsers: Spacy, AllenNLP and Stazna. The effectiveness of this algorithm was compared with two popular methods (Yake, Rake) on a dataset of English texts. Experimental results show that the proposed algorithm with the SpaCy parser is superior to other keyword extraction algorithms in terms of accuracy and speed. For the AllenNLP and Stanza parsers, our algorithm is also more accurate, but requires much longer execution time. The results obtained allow us to evaluate in more detail the advantages and disadvantages of the parsers studied in the work, as well as to determine directions for further research. The running time of the SpaCy parser is significantly less than the other two parsers because parsers that use transitions for deterministic or machine-learned set of actions to build the dependency tree step by step. They are typically faster and require less memory than graph-based parsers, making them more efficient for parsing large amounts of text. On the other hand, AllenNLP and Stanza use graph-based parsing models that rely on millions of features, which limits their ability to generalize and slows down the speed of analysis compared to transition-based parsers. The task of achieving a balance between the accuracy and speed of a linguistic parser is an open topic that requires further research due to the importance of this problem for improving the efficiency of text analysis, especially in applications that require real-time accuracy. To this end, the authors plan to conduct further research into possible solutions to achieve this balance.
H-Detect: an Algorithm for Early Detection of Hydrocephalus

Hydrocephalus is a central nervous system disorder which most commonly affects infants and toddlers. It starts as an abnormal build-up of cerebrospinal fluid in the ventricular system of the brain. Hence, early diagnosis becomes vital, which may be performed by Computed Tomography (CT), one of the most effective diagnostic methods for diagnosing Hydrocephalus (CT), where the enlarged ventricular system becomes apparent. However, most disease progression assessments rely on the radiologist's evaluation and physical measures, which are subjective, time-consuming, and inaccurate. This paper develops an automatic prediction utilizing the H-detect framework for enhanced accurate hydrocephalus prediction. This paper uses a pre-processing step to normalize the input image and remove unwanted noises, which can help extract valuable features easily. The feature extraction is done by segmenting the image based on edge detection using triangular fuzzy rules. Thereby, the exact information on the nature of CSF inside the brain is highlighted. These segmented images are saved and again given to the CatBoost algorithm. The Categorical feature processing allows for quicker training. When necessary, the overfitting detector will stop model training and thus efficiently predicts Hydrocephalus. The outcomes demonstrate that the new H-detect strategy outperforms the traditional approaches.

Spermatogenesis is a process of cell differentiation to produce fertilized sperm. Testis-expressed 15 (TEX15), an important gene in spermatogenesis, has been reported to be linked with male infertility in various populations. This study aimed to assess the association of single nucleotide polymorphism (SNP) TEX15 rs323347 with male infertile individuals in a Vietnamese cohort and further analyze the haplotypes of TEX15 rs323346 and TEX15 rs323347. A total of 401 unrelated males, including 202 male infertility patients and 199 healthy controls were genotyped for TEX15 rs323347 using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Using statistical methods, the results showed that the allele frequencies of TEX15 rs323347 were in agreement with Hardy-Weinberg equilibrium (HWE) (p-value > 0.05), but its genotype frequencies were not significantly different between male infertility patient and control groups (p-values > 0.05). However, the CA haplotype of the two variants (rs323346 and rs323347) increased the risk of male infertility (p = 0.046, OR = 2.547, 95% CI = 0.982–6.602). Thus, this study would enrich the knowledge of the impact of genetic factors on male infertility in the Vietnamese population.
