Authors: Trapitsin S.Y. , Granichina O.A. , Agapova E.N. , Zharova M.V.
Published: May 2024

The article is devoted to the study of the motivation and readiness of teachers to implement the target model of mentoring in order to identify and evaluate the factors influencing this process. We considered theoretical foundations of the organization of mentoring, possible approaches to the study of strategies for the behaviour of teachers during its implementation, and gave the characteristics of their manifestations. The results of study were obtained on a sample of teachers from 4 secondary schools in one of the districts of Saint Petersburg. We used the methods “Motivational profile”, “Determination of the motives of teachers’ work activity”, “Motivational readiness of the teaching staff to master innovations”, “Barriers preventing the development of innovations”, based on generally accepted methodology, proven research design, methods of data collection and analysis, which minimize the impact of systematic and random errors, reduce the reliability of the data. The results obtained show that teachers from different schools have similar characteristics of readiness for mentoring activities, which is largely determined by the level of motivation of teachers, the nature of their attitude towards mentoring, and the degree of understanding of its necessity and importance.

La fundamentalidad [autónoma] de los derechos: una sistematización de criterios
Authors: Duarte Molina Tirson Mauricio
Published: May 2024

La categorización de los derechos humanos en diferentes generaciones ha atentado contra la característica de indivisibilidad de estos, más aún cuando la Constitución de 1991 concibe una diferenciación entre aquellos que son y no fundamentales, lo que lleva a la implementación de diferentes medios de protección. No obstante, frente a tal problema, han surgido teorías sobre la conceptualización y su fundamentalidad. Por lo anterior, en este artículo se pretende abarcar aquella desde las teorías de la mutación de los derechos y el antropocentrismo, dando una revisión al contenido o núcleo esencial del derecho en cuestión.
Factors Affect Green Product Purchase Decisions: The Mediating Role of Green Brand Image
Authors: Thuy Oanh Thai Thi
Published: May 2024

Research on environmentally conscious consumer behaviour requires particular attention to Asian markets. Although Vietnam is an Asian developing nation with a noted environmental conscience, little is known about their green product purchase habits and decisions. Thus, the goal of this study is to investigate the factors influencing Vietnamese consumers' decisions regarding purchasing green products. The study evaluates a collection of theoretically proposed hypotheses using a convenience-based methodology. A 30-variable questionnaire was used to gather information from 347 residents. Exploratory and confirmatory factor analyses were used to analyse the data. The suggested theories were tested using structural equation modelling. The findings demonstrated that the customers were eager to support protecting the environment, aware of their environmental duties, and ready to look for information about sustainable goods. Supporting environmental protection, drive for environmental responsibility, green product experience, environmental friendliness of companies, social appeal, and green brand image are all recognised as significant variables that have a direct impact on consumers' decisions to buy green products. Additionally, the study discovered that the association between these factors and decisions to purchase green products is mediated by the image of green brands. By investigating the variables influencing Vietnamese consumers' preferences to buy environmentally friendly goods, this study offers insightful information on green purchasing habits in that country. The findings can help marketers create persuasive green marketing campaigns that highlight the environmental, social, and individual advantages aligned with the brand image linked to purchasing green products. These approaches will have positive impacts on their purchase decisions.

Solar Neighborhood Financing Mechanisms and Business Models
Authors: Wilczynski Eric
Published: May 2024

Since solar neighborhoods often span multiple land use spaces, local community members are key stakeholders in these developments. As such, involving the community can help promote and accelerate the investment and dissemination of these developments. In doing so, certain solar neighborhood business models can include individuals who otherwise cannot gain direct benefits from solar projects due to not having the ability to purchase their own solar equipment. Within the framework of IEA SHC Task 63, business models were developed to be flexible in terms of who sponsors the project versus who ultimately owns/hosts the completed development. This allows for models where community members can be involved in some way - either as sponsors of the project or as part of a customer base leasing or subscribing to the project's output.

Authors: Misri Muhamad Ali , Qadr Khelan Hussien , Rahmatullah Muhammad Avif
Published: May 2024

The SARS-CoV-2 coronavirus can spread through contact with contaminated surfaces. The use of hand sanitizer is claimed to reduce the risk of transmission. For this reason, this study aims to develop a model of the spread of COVID-19 using the SEIR model with the use of hand sanitizer for infected individuals. The individual population is divided into six compartments, namely two compartments for susceptible individuals who using hand sanitizer and not, one compartment for exposed individuals, two compartments for infected individuals who using hand sanitizer and not, and one compartment for individuals died and recovered. The results obtained two equilibrium points: the disease-free and endemic equilibrium point, and also the basic reproduction number. The existence of a disease-free equilibrium point is unconditional, while the endemic there exist when the basic reproduction number is more than one. Stability analysis of the disease-free equilibrium point is locally asymptotic stable when the basic reproduction number is less than one. Numerical simulations carried out also strengthen them. Finally, the results of basic reproduction number sensitivity analysis show that the basic reproduction number is strongly influenced by contact of the susceptible individuals with exposed and infected individuals, neglecting of hand sanitizer use, mortality and cure rates.
Word Formation Processes of COVID-19 Related Terms in Jakarta Post, BBC, and CNN Portals
Authors: Rosyadah Nabilah
Published: May 2024

The global pandemic known as Coronavirus Disease 2019 (COVID-19) has an impact on the use of language. The language used in COVID-19 news is frequently unfamiliar to the general public or even made up just for the pandemic. The goal of this study is to examine the word formation of COVID-19-related terms used in The Jakarta Post, BBC, and CNN portals. There are two research questions in this study, they are: (1) What are the types of word formation processes found in terms related to COVID-19? (2) How are the words related to COVID-19 formed? Moreover, this research uses Lieber’s theory (2016). This study uses a qualitative methodology. The findings of this study show that there are seven types of word formation: affixation, compounding, coinage, backformation, blending, clipping, and acronyms and initialisms. The conversion type is the process of word formation that has not been discovered. Words related to COVID-19 are formed by adding or removing an affix, combining or blending two words, expressing a specific object, and abbreviating a word. It can be concluded that many terms related to COVID-19 are the result of a word formation process that aims to form new words that will certainly give different meanings and different word classes from the original word. In the future, this research can be useful for readers who are looking for definitions of terms related to COVID-19, as well as for those who are interested in morphology or the field of word formation processes.
The Grammatical Cohesion Analysis of News Texts on The Russia-Ukraine War
Authors: Sahreebanu Dhea Syahzana
Published: May 2024

Grammatical cohesion is research that analyzes how each word, phrase, or sentence is connected in a text. The researcher conducted this study to identify the types of grammatical cohesion and know how these types work in news texts. Researchers chose to use a qualitative descriptive approach in conducting this research. The data source in this study is an online news text published on Wednesday, 19 October 2022, by The Jakarta Post entitled "Russia Bombs Cities Across Ukraine at Rush Hour in Apparent Revenge Strikes." To examine the news text, researchers used the theory of grammatical cohesion developed by Cutting (2002). After conducting the analysis, the researcher found thirty-five (35) forms of grammatical cohesion out of the thirty-three (33) datums found in news texts. Of the total findings, thirty-two (32) are reference forms, and the remaining three (3) are ellipsis types. On the other hand, substitution is not found in the war news text. The type of reference most often used is the endophora in the form of anaphora (13), followed by exophora (10), associative endophora (7), and endophora in the form of cataphora (2). From these findings, each type of grammatical cohesion has its role in the news text. The reference type works as a tool to refer to a reference point in the text. Meanwhile, the ellipsis type works as a tool to remove words or phrases that are deemed unnecessary. Even so, both types of grammatical cohesion function to avoid word repetition.

Published: May 2024

The perception of the women's inferiority in society has created significant issues in the form of oppression of women. Furthermore, literary works portrayed these issues to raise awareness because it has an important role as one of the means to address the issue of oppression against women. Shobha Rao's novel Girls Burn Brighter is a feminist literary work that highlights the oppression of women. This study aims to examine the oppression of main female characters as revealed in the novel through literary devices. This study used a sociological approach since the novel raise the social phenomena of female oppression which is examined through the perspective of feminist literary criticism. The researcher applies Iris Young's theory of oppression to explore the forms of oppression and Kimberly Crenshaw's theory of intersectionality to look out the factors of oppression experienced by main female characters. The results of this study found that the main female characters, namely Poornima and Savitha, experience oppression in the form of marginalization, exploitation, powerlessness, cultural imperialism, and violence. Their experiences of oppression manifest in the form of marginalization of job opportunity, sexual and labor exploitation, powerlessness to speak up, cultural imperialism of the dowry system, and physical and sexual violence. These forms of oppression are influenced by intersecting factors such as gender, social class, political power, skin color, and dominant culture.

Propuesta de mejora en los cumplimientos de tiempo para proyectos de construcción urbanos de una pyme constructora, basado en la filosofía Lean Construction y Estimación Basada en Tres Valores
Authors:   , Purizaca Ramos Ricardo , Pardavé Medina Gino
Published: May 2024

Actualmente, el sector de la construcción enfrenta desafíos debido a un modelo de producción tradicional deficiente, afectando especialmente a las pequeñas y medianas empresas (pymes) que operan en esta industria. Estas pymes experimentan pérdidas operacionales, sobrecostos y retrasos en sus proyectos. La investigación tiene como objetivo generar un nuevo conocimiento mediante la implementación de un modelo de mejora integrado para optimizar la gestión de producción en proyectos de construcción urbanos. El diagnóstico en una pyme constructora reveló problemas de incumplimiento de cronogramas en obras urbanas, especialmente en la gestión de obras. El modelo de mejora integrado, conformado por Last Planner System y la técnica PERT, fue validado mediante el juicio de expertos, cumpliendo con los criterios de validación y mostrando un impacto significativo en colaboradores; así como en la mejora de gestión de recursos y en la reducción de actividades que no generan valor en la pyme que lo implemente. En última instancia, se logró desarrollar un modelo de mejora integrado que gestione eficientemente la producción mediante una planificación y control del cronograma basado en un enfoque de trabajo "pull". Se espera que la implementación de este modelo en el sector de la construcción para pymes tenga un impacto significativo, mejorando la eficiencia, productividad y competitividad. Además, fomentaría una cultura de trabajo más colaborativa y participativa, contribuyendo al desarrollo sostenible a largo plazo del sector en su conjunto.

Authors:   , Salazar Carrasco Fernando , Segovia Gutierrez Shayla
Published: May 2024

Introducción: El desarrollo de nuevos medicamentos ha incrementado el tiempo de vida de las personas viviendo con VIH (PVV). Esto ha generado la necesidad de tratar otras infecciones crónicas como VHB y VHC. Sin embargo no está claro cuál es la sobrevida de las PVV con estas co-infecciones desde que se mejoró el acceso a antirretrovirales en el Perú. El objetivo es evaluar dicha sobrevida según diferentes características de las PVV. Métodos: Cohorte retrospectiva basada en la revisión de historias clínicas de todos las PVV con coinfección con VHB y/o VHC mayores de 18 años, atendidos entre los años 2010-2022 en un centro de referencia público de Lima, Perú. Se incluyó las PVV con al menos un año de seguimiento. Se calculó la probabilidad de sobrevida a los 5 años en total y según características clínicas y laboratoriales utilizando curvas de Kaplan Meier y la prueba Log Rank. Resultados: Se incluyeron 72 pacientes, con una media de seguimiento de 47.8 meses. El 87.5% de los pacientes presentaron coinfección VIH/VHB, mientras que el 12.5% restante VIH/VHC. No se encontraron pacientes coinfectados por los 3 virus. Del total, solo 8 pacientes (11.1%) fallecieron durante el tiempo de seguimiento. La probabilidad de sobrevida a los 5 años fue de 87.0% (IC 95% 75.3 - 93.4) en toda la muestra; 89.9% para coinfectados con VHB, y 83.3% para coinfectados con VHC. Las personas con mayor edad, menor conteo de CD4, mayor carga viral, menores índices hematológicos, y transaminasas elevadas mostraron una menor sobrevida, aunque estas diferencias no fueron significativas, a excepción del número de plaquetas en sangre. Conclusiones: La probabilidad de sobrevida a los 5 años en PVV con coinfección por algún virus hepatotrópico fue de 87.0%. Se observó menor sobrevida en pacientes con ciertas características clínicas y laboratoriales, aunque no hubo diferencias significativas, probablemente debido al pequeño número de la población estudiada, exceptuando las plaquetas.

Authors: Haryanto Rudy , Suaidi
Published: May 2024

The duties and functions of BAZNAS are regulated in RI Law Number 23 of 2011 concerning the management of zakat, namely planning, implementing, and controlling the collection of zakat in terms of distributing zakat and utilizing zakat including reporting and being accountable for the movement of zakat. To optimize the duties and functions of BAZNAS nationally, the Government issued a Decree of the Director General of Islamic Community Guidance No DJ. II / 568 / the Year 2004. Based on this decision, Baznas was born and formed for Pamekasan, Bangkalan, Sampang, and Sumenep Regencies on Madura Island. The strategy for procuring HR in the context of revitalizing Regency BAZNAS in Madura based on e-commerce/ digitization of zakat online is carried out following existing regulations, namely BAZNAS Regulation Number 1 of 2019 concerning procedures for appointing and dismissing Provincial BAZNAS and Regency/City BAZNAS leaders and circular letter from the Head of BAZNAS No. 3 of 2018 concerning the dissemination of the decision of the Chairman of BAZNAS number 24 of 2018 concerning guidelines for the management of amil zakat at Provincial BAZNAS and Regency/City BAZNAS. This strategy is not yet fully accommodating to online digitization-based services. The promotion strategy for revitalizing the Regency BAZNAS in Madura based on e-commerce/ online zakat digitalization is carried out directly and indirectly. In online digitization, promotions are carried out by uploading advertisements inviting people to make donations of zakat, infaq, and sadaqah at BAZNAS Regency in Madura through their website and Facebook. The potential application of e-commerce/ digitization of zakat online in the context of revitalizing BAZNAS districts in Madura is not yet representative in serving the collection of zakat, infaq, and sadaqah funds through digitalization online. Empowerment of the Community's economy through online digitization at the Regency BAZNAS in Madura has not yet been carried out because the digital application owned by BAZNAS Regency in Madura is not representative. After all, it is still done directly/manually.

Discussion of the proposed draft of new MABIMS criteria and draftof MUI criteria was made for a common interest and agreement deliberately forthe unification of the Hijri calendar in Indonesia. Some Islamic Organizationsin Indonesia had provided various views and attitudes towards the draft of thenew criteria. The views and attitudes of these mass organizations was various,and only the Islamic Union (Persis) had accepted and used these criteria since2012. The other organizations’ views were as follows: Nahdlatul Ulama(NU),expressly stipulated that the initial stipulation of Ramad}an, Syawal, danZulhijjah was based on rukyat, with hisab support. As like NU, al-Irsyad al-Islamiyyah was still guided with rukyat. For it, hisab was just as a tool forthe implementation of rukyat properly and effectively. Similarly al-Jam’iyatulWasliyah, which was consisten guided on rukyat, but chose to use the criteriaof the workshop results in Cisarua Bogor in 2011M. While Muhammadiyahuntil now had not determined the official attitude about the draft.

Electrochemically nitrate remediation by single-atom catalysts: advances, mechanisms, and prospects
Authors: Li Zhe , Yang Chuanju , Xu Bin , Yao Li , Zhu Wenlei , Cui Yibin
Published: May 2024

Electrocatalytic nitrate reduction reaction (NITRR) is highly desirable for remediating nitrate (NO3-) pollution and producing ammonia (NH3) under mild conditions. To date, great efforts have been made to fabricate selective, efficient, and stable electrocatalysts for NITRR. Among the numerous strategies, single-atom catalysts (SACs) have received extensive interest and investigations due to their cost-effective and maximum atomic utilization. However, the further development of SACs-based NITRR remains hindered by a poor understanding of their in-depth mechanisms. Consequently, this review summarizes the recent advances of SACs for the NITRR, including Cu-SACs, Fe-SACs, Zn-SACs, Co-SACs, and single-atom alloys. In addition, the characterization techniques for SACs and reaction pathways of NITRR are presented to give a robust understanding of SACs-based NITRR. Finally, we analyze the current challenges in fabricating SACs for NITRR, while the key factors for further improving NITRR performances are also examined.
Guiding lithium growth direction by Au coated separator for improving lithium metal anode

Published: May 2024

Lithium metal is the most promising anode for next-generation batteries due to its highest theoretical capacity and lowest electrochemical potential. However, its dendritic growth hinders its practical use due to the consequent poor reversibility, potential short-circuit, and safety concerns. Suppressing lithium dendrite is difficult since dendritic growth is thermodynamically and kinetically favorable. Herein, we guide lithium to uniformly deposit along the opposite direction to normal by a nanolayer Au coating on a commercial polypropylene separator. It prevents lithium dendrites from piercing the separator, instead of inhibiting dendrites growth only. Au is lithiophilic, and lithium is calculated to be more attracted to Au and is confirmed to uniformly deposit on Au at the separator side rather than on the current collector side. Furthermore, Au also regulates the morphology of deposited lithium from a mossy state to a bulky state. In this work, the symmetric cell with the designed structure achieves excellent electrochemical performances of a long-life cycle over 2,000 h at 1 C for 1 mA h cm-2. Pairing with LiFePO4 cathode as a full cell, lithium metal anode with Au-modified polypropylene separator exhibits extraordinary performance with a high Coulombic efficiency of 99.23% over 800 cycles at 1 C.

The main types and causes of degradation of photovoltaic modules, which are associated with both mechanical and environmental influences, as well as with the influence of electrical quantities during the operation of solar panels, are considered in detail. The main conclusions about the most influential degradation factors are obtained, among which it is advisable to highlight the influence of temperature - both the external air temperature and the heating temperature of the solar panel itself - for further study. An analysis of current research on the study of the peculiarities of degradation of photovoltaic modules under the influence of various factors associated with both environmental influences and the influence of electrochemical processes directly in the panel system is carried out. Particular attention is paid to studies of the effect of temperature on their performance. Preliminary experimental measurements of solar panel performance parameters at different light intensities and when the panel is heated in the range from 19 to 78 °C were carried out on the basis of a laboratory setup. Based on the data obtained, a graph of the dependence of the efficiency of a solar PV module on its surface temperature was constructed and it was found that the efficiency of the panel begins to decline actively after the temperature of its surface rises above 50-55°C. To confirm and detail the data obtained, the next task is to conduct similar studies with different types of solar panels and under different operating conditions. Also, the next step will be to further investigate the impact of ambient temperature on the efficiency of photovoltaic modules, as well as to find a specific link between the impact of this temperature on the heating of solar cells and, accordingly, to assess the impact of these parameters on the degradation of solar panels in general.

It is demonstrated that digital processing of information on electricity consumption is possible when transforming the studied process into a discrete form. The correct choice of the monitoring interval allows for the accurate reconstruction of the values of the studied function in the intervals between measurements. It is shown that when organizing the monitoring of average power, it is necessary to select a discretization interval that provides adequate representation of the current process. The proposed procedure for choosing the interval of electric power monitoring is based on determining the duration of the deviation of the random function of electric power change, subject to certain constraints. The justified number of monitoring studies is established to determine the optimal interval of electric power monitoring. It is shown that the most rational method of processing experimental data will be the method of joint estimation for correlation and standard deviation.
NON-INSTRUTIVE LOAD MONITORING – A PROSPECTIVE DIRECTION OF BUILDING ELECTRICITY CONSUMPTION MONITORING
Authors: Cherneshchuk Ihor
Published: May 2024

It is shown that in order to adapt to changing models of energy supply and increase reliability, utilities need intelligent monitoring of power grids in order to track dynamic operating conditions in distribution networks. Smart monitoring can provide utilities with a detailed description of consumer habits and maximize user awareness of consumption, leading to behavioural change and smoothing global energy demand. The driving factors of the smart home monitoring and security market are given. An increasing number of internet users, the rapid proliferation of smartphones and smart gadgets, and growing concern about remote monitoring of homes have been identified as key factors contributing to the growth of the smart home security market. It is shown that the Smart monitoring methodology on the example of a building reflects the goals of both actual monitoring and control: to reduce the energy consumption of buildings and/or to reduce electricity bills for residents; to offer grid managers more tools to better manage the growing demand and possible interruptions in energy production due to the growing integration of RES into the grid.
Non-intrusive load monitoring (NILM) is analysed – a method of analysing data on the total electrical load, obtained by measuring the current and voltage at one point, followed by the division of the total load into a load of individual devices, which can play a key role in the digital transition in the electric power industry. This technology is able not only to improve the current operational activities of electricity companies but also to form the basis of the formation of new relations between subjects of energy markets. NILM technology has seen significant success thanks to advances in machine learning, signal processing, and pattern recognition. It was determined that the fundamental stages of a typical NILM structure are data collection, feature extraction, signal decomposition, and device identification.

Buildings are currently one of the largest consumers of energy resources in Ukraine, including electricity[1], accounting for about 40% of energy consumption. In Ukraine, the requirements for energy consumption in buildings are regulated by the Law "On Energy Efficiency of Buildings" through the relevant energy efficiency classes[2]. The issue of improving the energy efficiency of these facilities is a global challenge at the global level. In particular, the 2019 UN Climate Summit set a goal to achieve zero energy consumption in new buildings by 2030 and the same level in existing buildings by 2050. The use of renewable energy sources is an absolute and necessary component of achieving these goals. In addition, it should be understood that the share of renewable energy will grow steadily, in particular in household facilities. Over time, every building will be powered by renewable energy in one way or another. A review of the literature on the design of energy-efficient buildings in terms of engineering systems design revealed a low level of coverage of issues related to the design and design of power supply schemes for buildings with RES[3-7]. The article presents existing circuit solutions for the integration of RES (solar photovoltaic generation) into the building power supply system, in particular, a building power supply system with a grid-tie inverter and power optimizers, a building power supply system with microinverters, a building power supply system with twin microinverters and a prefabricated combined switchboard, a building power supply system with a backup power source, a power supply scheme with redundancy and a smart controller. A variety of schematic solutions for the power supply system allows you to choose the one that will meet a single or a set of criteria: the location of the panels by the cardinal points (one side or several); redundancy; cost; "intelligence" of the system.

Orange peel waste (OPW), as a relevant and recoverable residue, is composed of peel, internal tissue, pulp, and seeds. This organic residue is rich in carbohydrates useful for biofuel production processes. Biohydrogen is obtained from dark fermentation (DF) and photofermentation (PF), which are complementary in the bioprocessing chain. The objective of this work was to compare the environmental impact assessment of a sequential dark–photofermentation process (Scenario DF-PF) and the individual fermentation processes: dark fermentation (Scenario DF) and photofermentation (Scenario PF). The assessment was performed at a laboratory scale, and the functional unit (FU) was defined as the production of 1 kg H2. Scenario DF showed the lowest environmental impacts regarding global warming and fossil resource scarcity indicators, with 375.5 kg CO2-eq/FU and 108.8 kg oil-eq/FU, respectively, followed by Scenario DF-PF and Scenario PF. Scenario DF-PF presented the lowest impact regarding the water consumption indicator (7.6 m3/FU), followed by Scenario DF, which had 46.6% more impact. Additionally, Scenario DF-PF required 3.3 times less substrate than Scenario DF due to more efficient substrate conversion. The high share of fossil fuels in the Mexican electricity mix directly impacts the processes that require electric energy, such as the PF process. Therefore, eco-friendly light sources should be used to minimize effects. Valorization of OPW could follow two routes depending on whether the aim is to reduce a specific environmental impact indicator or biowaste conversion efficiency.

A mathematical model was developed, during which the voltage equations of the three-phase winding of a brushless DC motor with permanent magnets, the electromagnetic torque of a brushless DC motor, electromagnetic power, the induced emf of each winding, and the differential torque equation of the servo system were obtained. Based on the constructed mathematical model of the BLDC for a specific motor with given parameters, simulation modeling was carried out and the dependences of electromechanical quantities were obtained: angular velocity of the rotor, electromagnetic torque, stator phase current and rotor rotation angle on time. The simulation results confirmed the theoretical justification of the mathematical model. The resulting mathematical description of the BLDC can be used to build the architecture of a control unit based on a neural network controller.
