Exploring the Association between Role Stress and Police Personnel's Mental Resilience: The Role of Work-Family Conflict and Psychological Well-Being
Authors: Jinu Rohan Thomas , Subathra K. , Senthilkumar S.
Published: February 2025

This study uses regression analysis to investigate the connection between police mental health and work-related stress. It focusses on the ways that role conflicts, job expectations, and work strain lead to stress, fatigue, and decreased productivity at work in an effort to offer suggestions for enhancing occupational health in law enforcement. A quantitative survey method was utilized to evaluate the impact of occupational stress on the mental well-being of police personnel in specific regions of Tamil Nadu. The research examined the association between role stress (including role conflict, ambiguity, and overload) and work-family conflict as a mediating variable, with psychological well-being serving as a moderating factor and resilience as an additional element. Statistical regression analysis was employed to assess these correlations. Police employees reported moderate to high levels of occupational stress, according to the analysis. According to regression results (p < 0.05), job stress and mental health are strongly inversely related, with role conflict and job overload having the most effects. Reduced mental health was associated with increased occupational stress. The study's scope is restricted to a few Tamil Nadu districts, which may limit its generalisability. Future studies might concentrate on stress-reduction techniques or use larger sample sizes. This study provides important new information about how work-family conflict, mental health, and occupational stress interact in law enforcement. The results give legislators useful information to improve law enforcement officers' resiliency and occupational health.

Published: February 2025

As classes multisseriadas apresentam desafios pedagógicos e estruturais que exigem práticas inovadoras e contextualizadas. Este artigo analisa o papel do professor como mediador do processo ensino e aprendizagem nesses contextos, explorando a articulação entre inovação pedagógica e o conceito de cidade educadora. Para tanto, utiliza-se uma abordagem qualitativa, fundamentada em revisão de literatura e análise de práticas pedagógicas aplicadas. A metodologia utilizada parte de um questionamento: Qual o papel do professor em uma Cidade Educadora? A importância de trabalhar pedagogicamente na cidade que educa considerando a sustentabilidade e suas dimensões econômica, social e ambiental a partir da sala de aula. O objetivo desta produção é levar os docentes, especialmente dos anos iniciais do ensino fundamental, a pensar em letramentos inovadores que tenham conexão com temas socais emergentes como os Objetivos de Desenvolvimento Sustentável (ODS). Como entendemos que as classes multisseriadas constituem lócus de possibilidades que oportunizam interações sociais e trabalho colaborativo entre os estudantes, partimos desse contexto inicial para um aprofundamento mais amplo a posteriori. Partindo da perspectiva do letramento sustentável, discute-se como a prática pedagógica pode contribuir para a formação de cidadãos críticos e atuantes, alinhando-se à prática dos Objetivos de Desenvolvimento Sustentável (ODS), em especial ao ODS 4. Os resultados indicam que a integração entre escola, comunidade e práticas sustentáveis potencializa a aprendizagem em classes multisseriadas, reforçando o papel da educação como eixo de transformação social.
Eficácia e importância da avaliação clínica da deglutição
Authors: Rabelo Luciana Avila dos Santos , Dantas Roberto Oliveira
Published: February 2025

Introdução: O corpo humano executa uma determinada função ao se alimentar, a qual promove a condução do alimento ao estômago. Esta função é denominada deglutição. A deglutição pode ser causada por doenças neuromusculares degenerativas, encefalopatias, demências, traumas de cabeça ou pescoço, ou acidente vascular cerebral (AVC). A avaliação clínica da deglutição, tem como objetivo identificar alterações da fisiologia da dinâmica da deglutição, fornecer a necessidade ou não de exames objetivos, identificar as fases comprometidas, o grau de severidade, a classificação da disfagia. Objetivo: investigar a coincidência dos resultados da avaliação clínica e da avaliação objetiva da deglutição (nasolaringofibroscopia), em pacientes com disfagia orofaríngea neurogênica, com diagnóstico de Acidente Vascular Cerebral (Isquêmico ou Hemorrágico), Doença de Alzheimer e Doença de Parkinson. Materiais e Métodos: Foram avaliados 35 pacientes, 6 do gênero feminino e 29 do gênero masculino, que apresentaram a faixa etária de 52-82 anos. A avaliações foram realizadas no mesmo dia, sendo feita primeiramente a avaliação clínica seguindo protocolo proposto por Silva (2004) e posteriormente a avaliação nasofibroscópica da deglutição, seguindo protocolo proposto por Langmore et al (1988); Aviv et al (1998); Macedo Filho (2003). Resultados: Ocorreram coincidências entre os achados dos resultados da avaliação clínica da deglutição, tendo como padrão a avaliação nasofibroscópica. Houve uma forte correspondência e associação entre as escalas da avaliação clínica e nasofibroscópica. Conclusões: Com base nos achados adquiridos neste estudo, conclui-se que a avaliação clínica da deglutição deve ser realizada no paciente com disfagia orofaríngea neurogênica, pois o fonoaudiólogo pode determinar um diagnóstico adequado, classificar a disfagia quanto ao tipo e grau de severidade; detectar os problemas durante a deglutição; auxiliar na conduta terapêutica; determinar qual via de alimentação e determinar quais manobras específicas da deglutição podem ser utilizadas no paciente avaliado. Dentre as limitações podem ser incluídas o tamanho da amostra. Sugere-se para trabalhos futuros, a ampliação do escopo da pesquisa em outras populações, estudos randomizados para aprimoramento da evidência científica.

A relevância deste estudo reside na necessidade de abordar lacunas existentes sobre o tema, que ainda carece de debates mais aprofundados. Espera-se que os resultados desta pesquisa possam auxiliar as universidades em seu processo de adaptação às novas regras estabelecidas pelo MEC, conforme as diretrizes curriculares nacionais.
Pharmacists’ Perceptions Regarding e-pharmacies in the Aftermath of CoViD-19 Pandemic
Authors: CHYTA Christina , TZIORTZI Athanasia , KATHARAKI Maria
Published: February 2025

The CoViD-19 has altered service delivery and posed chal­lenges to e-commerce while also facilitated the online phar­macies presence. Online pharmacies improve the consumer healthcare experience by affording convenience, efficiency, greater confidentiality, and improved access to medicines. The objective of this study is to examine the perceptions of physical store pharmacists towards online pharmacies and whether their perspectives have changed due to the CoViD-19 pandemic. A cross sectional study took place during the second trimester of 2022. Data were collected via a struc­tured anonymous questionnaire with closed-ended ques­tions, encompassing demographic information and pharma­cists' perspectives on online pharmacies. The Cronbach's alpha coefficient yielded a value of 0. 70. Non-parametric sta­tistical tests were applied to explore relations between demographic characteristics and pharmacists' views regard­ing online pharmacies. Correlation between categorical and ordinal data was assessed with Spearman's correlation coef­ficient. Multiple linear regression analysis was conducted to examine the effect of demographics and their perceptions on their intention to create an online pharmacy. The statistical significance threshold was set at 0.05.The study sample consisted of 129 pharmacists, 71 women (55%) and 58 men (45%). The majority of pharmacists exhibit a strong affinity for technology. While all respondents recognize the benefits of online pharmacies, several remain neutral or hesitant about establishing such ventures. Looking ahead, a significant proportion of pharmacists who currently operate only physical pharmacies express positive attitudes towards creating an online pharmacy. The findings clearly indicate that, the onset of the CoViD-19 pandemic prompted a significant proportion of them to consider implementing an online pharmacy in a positive light. Pharmacists are expected to make decisions to keep up with technological progress and consider the online image of their pharmacies. As a result, they can benefit from all the advantages offered by online pharmacies while allowing consumers to choose their preferred method of purchase.

Published: February 2025

There are various challenges in integrating ideological and political education into calligraphy teaching. In the teaching, the ideological and political content of the course cannot be closely linked with calligraphy teaching. Teachers do not have a deep understanding of the ideological and political content of the course, the teaching methods are boring, and students' learning interest and efficiency are not high. In order to improve the effectiveness of the integration of curriculum ideology and politics into calligraphy and improve students' comprehensive quality, interviews were conducted with students, professional teachers and administrators of Baise College in the form of interviews, which summarized the influential factors affecting the implementation of curriculum ideology and politics, and proposed more meaningful teaching strategies for future teaching.
Cooperative Learning through Education and Training in Anhui Province China
Authors: Shao Longqin
Published: February 2025

The purpose of this study is to investigate the role of cooperative learning in education and training within farmers' cooperatives in Anhui Province, China, and to assess its impact on their development. This research holds significant implications for enhancing the operational effectiveness of farmers' cooperatives, refining the cooperative education framework in higher education institutions, and advancing rural modernization initiatives. Utilizing a quantitative research methodology, the research analyzed the basic characteristics, participation levels in higher education training, and overall effectiveness of 157 farmers’ cooperatives. A descriptive survey design was employed, targeting formal cooperative members, with data collected through a custom-designed questionnaire. The findings reveal that over two-thirds of the cooperatives have received training from universities, focusing primarily on marketing strategies, policy compliance, and agricultural production techniques. Approximately 70% of respondents acknowledged that university training significantly contributed to the development of their cooperatives; however, one-third expressed that its impact was limited. The study identified several challenges faced by cooperatives, including deficiencies in technical skills, inadequate policy support, and insufficient management capabilities. Furthermore, it was noted that university training often lacks continuity and relevance to the evolving needs of the cooperatives. To foster sustainable development within these farmer cooperatives, we recommend enhancing the relevance of training content, innovating training delivery methods, and promoting robust government policy support alongside increased financial investment. This study serves as a crucial reference for achieving rural modernization and improving farmers' income levels through effective cooperative strategies.
Myerson's Lemma under Fuzzy Valuation
Authors: Dai Lixing
Published: February 2025

The paper explores extending Myerson’s lemma, a key concept in mechanism design, to situations where participants' valuations are imprecise. Traditional game theory assumes precise valuations, but real-world scenarios often involve uncertainties. By introducing fuzzy set theory, the paper addresses this issue, allowing valuations to be represented as fuzzy numbers. The study proves that even under fuzzy valuations, the auction mechanism can still satisfy dominant strategy incentive compatibility (DSIC). Practical applications are discussed, including auctions in online advertising where click-through rates (CTR) are uncertain. The paper demonstrates how fuzzy valuation can ensure fairness and efficiency in these auctions, offering a more realistic approach to mechanism design in uncertain environments.

Published: February 2025

Melanoma is one of the forms of skin cancer that affects people worldwide. Research indicates that nearly 75% of the global population has been impacted by melanoma. Early detection and treatment of melanoma significantly increase survival rates. However, detecting melanoma in its early stages can be challenging because dermatologists typically rely on visual examination and biopsy analysis, which is both time-consuming and labor-intensive. This highlights the need for automated, efficient methods to identify melanoma at earlier stages. Skin cancer is generally classified into two categories: melanoma and benign tumors. The goal of this study is to facilitate the early detection of melanoma by employing deep learning techniques, specifically convolutional neural networks (CNNs), to distinguish between melanoma and benign lesions using the ISIC dataset. The proposed model achieves an accuracy of 80.80%, outperforming previous approaches by offering faster and more accurate melanoma detection.
Existential Crisis Behind the Plague Writing in Pale Horse, Pale Rider
Authors: Wang Shujin
Published: February 2025

American author Katherine Anne Porters novelette Pale Horse, Pale Rider takes the First World War and the Great Pandemic of 1918 as the background. Through some modernist techniques such as stream of consciousness and non-linear narrative, the story focuses on the chaotic and broken feelings of the heroine Miranda during her illness. The illness experience offers an opportunity for Miranda to think about life. In this case, Mirandas existential crisis, haunting and difficult to solve, is revealed through the psychological description during her illness and the implication of the modernist narrative techniques. In addition, descriptions of peoples lives during the war exposes great oppression of the war on people, suggesting social cause of Mirandas existential crisis. Through analysis of the plague writing and the social situation in the text, this essay will conclude that modernist plague writing is a manifestation of the existential crisis, and the plague has symbolic meaning in the text, implying the existential crisis of Americans under the influence of the First World War.
Central Bank Digital Currencies(CBDCs) and the Global Monetary System: Behavioral Impacts and Policy Implications
Authors: Hu Bowen
Published: February 2025

The advent of the Central Bank Digital Currencies (CBDCs) marks a turning point in global money. With the rise of digital currencies such as Bitcoin, CBDCs provide a platform for central banks to continue to administer monetary policy while taking part in the digital economy. In this article, we examine the behavioural and macroeconomic effects of CBDCs with regard to how they could affect consumers, national economies and global financial markets. Based on the experimental data and observational findings, the paper considers the effect of CBDCs on the consumers finances (spending and saving), and whether it can overcome such issues as high transaction costs and financial exclusion. It also studies the macroeconomic impact of CBDC adoption, such as inflation, GDP growth and economic activity. The report concludes with policy guidance for central banks and regulators on privacy, security, and financial inclusion as considerations for CBDC design and implementation. The conclusion is that CBDCs can have significant effects but must be designed and used in such a way as to ensure that they do not cause undesirable consequences to personal habits and national economies.
The Current Situation of Educational Equity in Chongzhou City, Sichuan Province since China's reform and opening up
Authors: Yu Yi
Published: February 2025

Since China started its reform and opening-up, there has been progress in making education fairer. This study looks at Chongzhou City, Sichuan Province, to see the successes and problems of education fairness policies. It uses reviews of studies, policy analysis, and data to find key issues like unfair resource sharing, teacher movement, and gaps in education quality between cities and villages. Good changes include better rural school buildings, fewer dropouts, and teacher rotation programs. However, city schools still have more resources, better teaching, and better results for students than village schools. This shows there is still a need for focused plans. Suggested fixes are improving village schools, encouraging teachers to work in villages, giving more digital learning tools, and checking how policies are working. Fixing these problems in Chongzhou can help solve similar issues in other areas and support education fairness in China.

Authors: AL- Masarwah Thamer Ibrahim , Al-Thunebat Sateh , Almazaidah Ismail Suliman
Published: February 2025

This study aims to highlight the instances of silence in discourse and its meanings within the narrative context. Silence, a core element of verbal expression, fosters openness to diverse meanings and enriches narrative discourse. It is also a facet of speech, conveying and establishing meaning. The study is focused on the novel Returning to Haifa because silence is a crucial element of the narrative discourse and contributes to its formation. Silence permeates various elements of the novel, including characters, time, and place. The study also seeks to demonstrate the role of silence in conveying meaning and establishing significance, as it has a clear impact on changing the direction of the narrative and enhancing the suspense between the reader and the text. This makes the reader a co-creator of the text within the boundaries of both the spoken and unspoken elements.
The Art of the Unsaid: Analyzing the Use of Conversational Implicature in Political Communication
Authors: Ghawaidi Shaikah H. , Alsmari Nuha A.
Published: February 2025

This study investigates the use of conversational implicature by Saudi Crown Prince Mohammed bin Salman (MBS) during a September 2023 interview with Fox News. The research is grounded in Grice’s conversational maxims and the theory of implicature, focusing on how conversational implicature is strategically utilized to navigate sensitive topics and influence public perception. Using a qualitative research design grounded in Grice’s theory of implicature, the analysis highlights the frequent flouting of conversational maxims—particularly quantity, relation, and manner—to avoid direct responses, reframe controversial questions, and maintain diplomatic flexibility. The findings indicate the frequent use of particularized conversational implicatures (PCI) tied to specific geopolitical contexts, where MBS relies on context to imply meaning without making explicit statements. Conversely, generalized conversational implicatures (GCIs) were observed in broader discussions on Saudi Arabia's military and economic strategies, where meaning is naturally inferred without dependence on specific contexts. The findings suggest that MBS effectively employs implicatures to manage multiple audiences, deflect criticism, and shape public perception. Future research could expand on these findings by analyzing a wider range of interviews and incorporating non-verbal cues.

The decline in public transportation usage in Sri Lanka, due to inadequate service quality, reflects significant challenges for suburban mobility. Against this background, this study investigates the factors influencing bus passengers' service quality expectations on the Mawanella-Rambukkana bus route, providing insights into the need of improving public transport services at suburban levels. The existing literature indicates the key service attributes such as the ticket price, waiting time, and environmental conditions that significantly affect passenger satisfaction. However, there is a gap in understanding these factors in suburban contexts, particularly gender-specific preferences in Sri Lanka. A conjoint analysis was conducted to evaluate six critical service quality attributes: walking time, waiting time, ticket price, travel time, in-bus environment, and bus stop environment. The data was collected from 400 passengers, including 197 males and 203 females, using a structured questionnaire. The utility estimates and relative importance scores quantified the impact of each attribute. The study revealed a significant set of gender differences in service quality priorities. The ticket price emerged as the most crucial factor for both genders, with a slightly higher importance for the females (27.125) than the males (26.807). The males valued the bus stop environment (19.189) more than the females (19.065), while the females prioritized the in-bus environment (17.822) more than the males (17.044). The waiting time was more critical for the males (14.485) compared to the females (13.981), while walking time and travel time were of lower importance for both genders. The findings underscore the need for certain public transport actions such as targeted improvements in fare affordability, waiting times, and environmental conditions to enhance passenger satisfaction. The study addresses thus an existing literature gap by focusing on suburban bus passengers and providing gender-specific insights, contributing to a comprehensive understanding of the public transport service quality experienced by the people of Sri Lanka.
KEYWORDS: Service quality, passenger expectations, conjoint analysis, gender difference, suburban mobility, ticket price.

Development of Congestion Management of a Deregulated Power System Using Fuzzy Logic
Authors: Sari C. A. , Samsudin A. , Jaffar K. , Azmi E. F. , Sarif N. M.
Published: February 2025

Regulated systems are used in certain countries, including Malaysia. The electricity power market's whole system is owned by only one organization, mainly the government. This monopoly principle happened causes the market to be uncompetitive and consumers have very little right to the set price. Thus, this will require a system change which is the deregulated power system. This system will unbundle all the generations, transmissions, figure distributions into separate ownerships. The different ownership will bring a competitive power market since consumers are free to choose organizations that provide the best price and services based on their needs. However, an overly competitive market will lead to a congestion problem in the transmission lines. Congestion refers to the condition where there is insufficient power matching between generation and transmission networks. Thus, congestion management is needed to control demand for electricity and finding better methods rather than building new construction for generation. Several methods have been used to control congestion. Classical Methods are not suitable since they have complex formulation and are unable to solve real-world significant power system problems. In these recent years, the implementation of Artificial Intelligence Method can solve a large-scale power system problem. The Fuzzy Logic Method is one of the methods under Artificial Intelligence Method. So, in this paper, Fuzzy Logic Method is used to analyze congestion problem. The principle used by Fuzzy Logic is “IF X AND Y, THEN Z”. This method deals with approximation rather than precision. The data used in this paper are data from the Reliability Test System 1996.
Improving Tower Grounding and Insulation Level vs. Line Surge Arresters for Protection of Subtransmission Lines
Authors: Eghtedarpour Navid
Published: February 2025

Since renewable wind power plants are usually installed in mountain regions and high-level lands, they are often prone to lightning strikes and their hazardous effects. Although the transmission line is protected using guard wires in order to prevent the lightning surges to strike the phase conductors, the back-flashover may also occur due to tower footing resistance. A combination of back-flashover corrective methods, tower-footing resistance reduction, insulation level improvement, and line arrester installation, are analyzed in this paper for back-flashover rate reduction of a double-circuit 63 kV line in the south region of Fars province. The line crosses a mountain region in some sections with a moderate keraunic level, whereas tower-footing resistance is substantially high at some towers. Consequently, an exceptionally high back-flashover rate is recorded. A new method for insulation improvement is studied and employed in the current study. The method consists of using a composite-type creepage extender in the string. The effectiveness of this method for insulation improvement of the string is evaluated through the experimental test. Simulation results besides monitoring the one-year operation of the 63-kV line show that due to technical, practical, and economic restrictions in operated sub-transmission lines, a combination of corrective methods can lead to an effective solution for the protection of transmission lines against lightning.
Knubbsäl och storskarv i ett skyddsområde för fisk i Bohuslän : inventeringar i 8-fjordarområdet
Authors: Lundström Karl , Svedberg Kristina , Wolf Robin
Published: February 2025

Som en åtgärd för att återetablera nedfiskade lokala bestånd av olika arter av torskfisk och plattfisk inrättades år 2010 ett skyddsområde för fisk i havsområdet innanför Orust och Tjörn (8-fjordarområdet). Eftersom fiskbestånden i området inte visat några tecken på återhämtning har andra påverkansfaktorer än fiske uppmärksammats som tänkbara förklaringar, bland annat predation från knubbsäl (Phoca vitulina) och storskarv (Phalacrocorax carbo). Kunskapen om förekomsten av säl och skarv i anslutning till skyddsområdet för fisk är emellertid bristfällig. Här presenteras resultat från olika inventeringar av knubbsäl och storskarv som utförts i området runt Orust och Tjörn, inklusive 8-fjordarområdets skyddsområde för fisk.

Den nationella miljöövervakningen av knubbsäl i augusti och inventeringar av häckande storskarv i maj-juni visar att populationerna av knubbsäl och storskarv har ökat i storlek under 2000-talet såväl i Skagerrak som i området runt Orust och Tjörn. Inventeringsresultaten tyder även på att ökningen avstannat under senare år och att framför allt antalet knubbsälar nu ser ut att minska. Den nationella kustfågelinventeringen i maj-juni och den nationella vinterräkningen av sjöfågel i januari visar att förekomsten av både knubbsäl och storskarv är betydligt större i områdena utanför Orust-Tjörn och i närheten av skarvarnas kolonier än i skyddsområdet för fisk innanför Orust-Tjörn. Inventeringarna indikerar dock inga tydliga ökningar varken av knubbsäl eller skarv i området under 2000-talet. Den nationella kustfågelinventeringen och den nationella vinterräkningen av sjöfågel ger en bild av långtidsförändringar i förekomst av storskarv, men inventeringarnas geografiska täckning är begränsad, förutom i kustfågelinventeringen 2001–2013 och de år vinterräkningen gjorts med flygplan. Ett större antal årligt inventerade rutor eller sektorer i området runt Orust och Tjörn skulle ge ett bättre underlag. Genom att lägga till en hösträkning av sjöfågel skulle man även få bättre förståelse för hur antalet storskarvar varierar mellan områden och år under en period då antalet skarvar i området är som högst.

Förekomsten av knubbsäl och storskarv i skyddsområdet för fisk varierade tydligt mellan olika årstider. Antalet sälar var som högst under vintern, men med stor variation mellan år beroende på isutbredningen, medan antalet skarvar var som högst under hösten. Det syntes inga tecken på att sälar och skarvar förekom i större tätheter i specifika vattenområden. De olika inventeringar som bedrivits i området runt Orust och Tjörn ger liknande resultat om förekomsten av storskarv i skyddsområdet. Den del av skyddsområdet som inventerats varje månad 2019-2021 uppskattades hysa upp till 200 skarvar vintertid och upp till 800 under hösten. Antalet knubbsälar var betydligt färre, oftast bara några tiotal.
Nätprovfisket i Vättern 2023
Authors: Rogell Björn
Published: February 2025

Sötvattenslaboratoriet vid institutionen för akvatiska resurser, SLU Aqua, genomförde sommaren 2023 ett nätprovfiske i Vättern. Provfisket är en del av övervakningsprogrammet för Hjälmaren, Mälaren, Vänern och Vättern, som SLU Aqua utför och är datavärd för. Provfisket genomfördes med bottensatta översiktsnät av typen 'Stora sjöarna' (Bss) mellan 2023-07-17 och 2023-08-10. De lokaler som provfiskades var Fingals, Norrgrundet, Kråk/Flisen, Tängan och Lakaskär. Väderförhållandena under provfisket var mycket dåliga, vilket ledde till att 5 nät inte kunde läggas och att 3 nät var tvungna att flyttas från planerad plats. Totalt fångades 12 arter i provfisket varav sik var den dominerande arten sett till både antal och vikt. Fångstutvecklingen analyserades för förändringar över tid med avseende på antalet fångade individer och deras längdfördelningar. Mellan åren 2005 och 2023 har antal och vikt per ansträngning ökat av lake, sik och röding, medan gers har minskat. Öringen har ökat i antal men ökningen i vikt är inte statistiskt säkerställd. Abborrens längd har ökat och gersens längd har minskat.

The article shows the importance of analyzing old wood strength properties in restoration and monitoring the structure's condition. The issue of the characteristics of wooden structures destruction in the salty water of the Gulf of Finland is discussed. In particular, wood's physical and mechanical properties are analyzed during the long-term operation in water. The result of testing of small standard samples for different types of stress states is shown. Changes in the chemical composition of wood are identified. The change in the chemical composition of the material affecting its strength properties is described on the example of Fort Kronschlot crib foundation. It has been established that the process of diffusion, amplified by alternating wave loads, led to the washing of extractive substances, a decrease in potassium, and a lack of calcium in the cell walls of tracheids. The results of this research work may be useful in assessing the residual life of long-term wooden structures underwater and in predicting the restoration time for these structures more accurately.

Background: Anaemia is an error in the biological system which can lead to mortality if the condition deteriorates. India is one of the world’s leading contributors of anaemia. The major reason for this disease is malnutrition and women of reproductive age (WRA) and children are one of the most vulnerable groups to this condition and maternal anaemia is associated with increased mortality.

Methods: We have compared three devices Device A (HemoQR) and Device B(Hemocue) and Device C [Haematology Analyzer-Fully Automated-5 parts (Cellenium Junior)] in multiple primary healthcare centres (PHCs) using 400 samples from patients of different age groups using fingertip pricked blood for the test.

Results: The sensitivity, specificity and accuracy obtained from our study was 91.27%, 95.30% and 90.45 % respectively. The results of this study were satisfactory when compared to the criteria of Anemia Mukt Bharat” (AMB) program initiated by the government of India’s Ministry of Health & Family Welfare which states a sensitivity and specificity of 80% minimum for an invasive digital hemoglobinometer.

Conclusion: The study concludes that HemoQR can be an efficient, economical and smart point of care (POC) haemoglobin (Hb) detection test system using a mobile based application for analysing and collecting the data.

A peel-off gel face mask is a type of face mask that comes in a gel form, which can be applied to the face, dries, and can be directly peeled off from the skin. This research aims to determine the difference between the peel-off gel mask’s gelatin-based active ingredients that have anti-bacterial and anti-inflammation properties from staphylococcus aureus. The research design used in this study is a Complete Block Design with 2 factors, namely the comparison of dragon fruit extract and papaya leaf extract with the addition of gelatin. Factor 1 comparison of dragon fruit extract and papaya leaf extract (A1 = 80: 20%, A2 = 70: 30%, A3 = 60: 40%), factor 2 addition of gelatin (B1 = 1.5%, B2 = 2%, B3 = 2.5%). The analysis carried out on peel-off gel masks is physical and chemical properties, as well as organoleptic tests. The research results indicate that the difference in concentrations of dragon fruit extract and papaya leaf extract with the addition of gelatin has a significant effect on antioxidant activity, viscosity, adhesive time, drying time, antibacterial inhibition, and organoleptic testing. Based on the results of the physical and chemical tests of the peel-off gel mask, the recommended antioxidant activity is sample A1B1 (69.58%), and the sample with the highest antibacterial inhibition is sample A3B3 (13.50 mm).

There were two methods of green tea processing, namely the panning method and the steaming method. The panning method often produces unstable quality of tea because temperature and pressure of the heat on the process are not evenly distributed, so that green tea becomes burnt, or the polyphenol oxidase enzyme not inactivated as well. Therefore, green tea processing was developed using the steaming method. This research aimed to determine the effect of steaming time and draining time on the color of green tea brewed water with different brewing media. This study used the Randomized Complete Complete Block Design (RCBD) method with 2 factors. The first factor is length of steaming time with 3 levels, there are 2 minutes, 3,5 minutes and 5 minutes. The second factor is length of draining time with 3 levels, 0 hours, 2 hours and 4 hours. The results showed that steaming time had a significant effect on the G, B, L* and ∆E values of the brewed water color with Le Minerale. However, it didn’t significantly affect the R value with Le Minerale, the R, G, B, L* and ∆E values with distilled water and Gambung water. The draining time significantly affected the R, G, B, L* and ∆E values of the brewed water color with Le Minerale, as well as the G, L* and ∆E values with Gambung water. However, it did not significantly affect the R, G, B, L* and ∆E values with distilled water, the R and B values with Gambung water.

At present, the Russian Federation pays increased attention to the spatial organization of economic policy (national, regional). In the framework of this study, continuing their work, the authors of the section turn to the allocation of such objects on the ground as special-purpose objects - burial sites (burials), the formation of functional-territorial zones of the cemetery, the establishment of a certain visiting regime, use, etc. on their territory. The authors consider some features of such land use, taking into account the importance of resolving the issue of inventory, cadastral activities and cadastral registration of the territories and objects under consideration, functional zones, which forms the information component of the land plots occupied by special-purpose objects - burial sites. It is noted that the problem under consideration is quite large-scale. According to the latest data, unregistered and, accordingly, not put on cadastral registration of land plots allocated for burial sites account for about 65% of the number of existing cemeteries. At the same time, various environmental standards and requirements for the permissible maximum area of such land plots are violated. As a result of the lack of cadastral registration of land plots occupied by cemeteries, they have completely dropped out of the legal field and control of local governments, which causes significant damage to the environmental and social safety of municipalities where these special real estate objects are located. According to research in Russia, about 85% of cemeteries are either ownerless or not registered, which means that they are actually illegal. The lack of information systems and established forms of reporting documentation for the registration of cemeteries has led to a complete lack of information on land plots occupied by cemeteries, and has also deprived local governments of the opportunity to manage these lands.
THE PROCESS OF INTEGRATING ESG-PRINCIPLES TO CORPORATE GOVERNANCE PRACTICES
Authors: Kadol Natal'ya
Published: February 2025

Socio-economic challenges require new approaches and co-operation, as well as the development of social responsibility. The introduction of ESG principles into the practice of corporate governance becomes an important mechanism of transformation of business oriented towards sustainable development, which underlines the relevance of the work. It is noted that the integration of ESG principles into the management process provides a holistic approach that adjusts the environmental, social and management practices of the company to improve its sustainability. It is shown that the process of integrating ESG principles into management practices involves an assessment of both the environmental and social impacts of companies and an assessment of the economic performance they receive. Such an assessment will help to identify weaknesses that need to be optimised by the company, as well as the positive and negative impacts on the surrounding ecosystem and society. An algorithm is proposed for introducing ESG principles into corporate governance practice, which involves the implementation of certain stages. It is revealed that the integration of ESG components into corporate governance practices opens up opportunities for companies to win the trust of investors, gain customer loyalty, reduce operating costs, and improve financial performance. It is noted that the integration of ESG components into corporate governance practices is usually implemented through internal programmes, as well as through the creation of various initiatives.
