Traditional cost accounting is aimed at identifying costs that are incurred on an ongoing basis in connection with operating activities. The concept that supports the decision-making process in the long term is strategic cost management. The purpose of the article is to identify the tools for strategic decision-making in cost management focused on the corporate strategy of an enterprise. It is determined that strategic cost management is a process of making decisions on specific cost drivers in the context of the company's development strategy and value chain. An enterprise should evaluate its value chain in comparison with similar chains of competitors. The article presents a methodology for such an assessment. It is proved that strategic management is based on the following assumptions: connection with the value chain, strategic positioning of the enterprise, analysis of cost drivers, the client is the starting point for decision-making and activities, which results in the adoption of the market price as the basis for cost planning and product development, implementation of cost management in the early stages of the product life cycle, since the cost is largely determined by the product features determined at the stage of its design and development. A key element of targeted analysis is cost estimation in terms of the impact of specific factors (drivers). Strategic cost drivers are determined based on the implementation of the development strategy and its connection with the value chain. There are two main types of them: structural cost drivers and implementation cost drivers. It is substantiated that strategic cost management involves the use of product life cycle costing. Depending on the phases of the product life cycle, various management methods based on basic models are used: "ABC-Costing, Target-Costing. Strategic positioning of the company in terms of costs incurred should be carried out by means of cost benchmarking, which is aimed at comparing the costs incurred by the company and its competitors. The subject of comparisons is the cost of processes that allow achieving a competitive advantage.

Identity reconstruction of black African learners in a Muslim primary school.
Authors:   ,   University of KwaZulu-Natal, Makhanya Euphemia Nonhlanhla.
Published: April 2024

The overarching objective of this study is to explore and understand how Black African Learners (BAL) reconstruct their identity and how this influences their lives. Learner identity ‘reconstruction’ is still under-researched, especially in Muslim schools. This is supported in literature, where it is highlighted that regarding learner identity studies, the becoming and changing process is either neglected or not ascribed much significance (Lundgren & Scheckle, 2019, Kerr, Dean & Crowe, 2019). The rationale for conducting this study is mainly rooted in my personal experiences and observations as a teaching practice assessor, an employee in one of the higher education institutions in KwaZulu-Natal, Durban. The framework that underpinned this study was Social Identity Theory (SIT) by Henri Tajfel (1974). This theory assisted me in exposing what learners think and how they interpret their educational experiences, which include what they see and how they feel about multiple realities in their school, across, within, and between cross-cultural and post-disciplinary boundaries, as proposed by Wilber (2005) and Marquis (2007). An interpretivist paradigm and qualitative case study was adopted. One Muslim Primary School (MPS) and five learner participants were purposely selected. Data was generated utilising written narratives, semi-structured one-on-one interviews, and focus groups discussions where these were transcribed and thematically analysed. The findings of the study revealed that identity reconstruction of BAL in MPS represent a lever that can perpetuate or decrease inequality; depending on how it is philosophically interpreted. Immigration was viewed as one of the precursors for identity reconstruction sparked by immigration of BAL families from other parts of the continent into South Africa. Furthermore, BAL encounter a wide range of experiences that incorporate more painful, positive, and even contradictory, perceptions about self. The study concludes that identity reconstruction in an MPS ought not to be framed by foreign conceptions, but should rather be anchored in local, indigenous knowledge systems and practices. Instead, BAL should build up their Black African dignity and reclaim African-Muslimcentric identity; something to look forward to as democracy matures in South Africa, as BAL individually and uniquely reconstruct their identity.
Efficacy Analysis of Online Artificial Intelligence Fact-Checking Tools
Authors: Hartley Russell
Published: April 2024

Investments in artificial intelligence (AI) spurred development of online fact-checking tools; positioned to potentially serve as more accurate alternatives or appendages to search engines and/or nascent chatbots. This study analyzed the efficacy of four AI tools (ClaimBuster, Full Fact, TheFactual - IsThisCredible?, and Google’s Fact-Check Explorer) in producing accurate readings measured by a consensus of independent fact-checking organizations. 10 unique claims were inputted into each tool to produce individual fact-check reports, resulting in 40 fact-check reports being conducted. The results reflect an efficacy rating of 100% regarding the ability of the selected tools to produce an overall accurate reading with 89% of reports producing a unanimous determination. Additionally, recommendations were made to further map and analyze the efficacy of AI fact-checking. These findings support the notion that AI can play an effective role in aiding online truth-seeking when its determinations depend on transparently referencing its source of independent human fact-checkers.

Published: April 2024

Ao adentrar na leitura, possivelmente, você vivenciará um encontro com muitas vidas. O conjunto de cartas aponta para as mais diferentes relações que o amor faculta a cada um de nós: amor filial; amor paterno; amor materno; amor fraterno; amor conjugal; amor amigo; amor próprio; aumor de quatro patas. No mosaico do amor, a cada tempo, uma ou outra dimensão fica mais evidente, mas é sempre na multiplicidade das experiências que vamos nos sabendo amados. Na escola da vida, com cada pequeno gesto, as pessoas que por nós passaram e nós mesmos que no mais intimo também nos perpassamos, vamos reconhecendo aquele filete de tinta que foi escrevendo e inscrevendo no sulco mais profundo de nossa história as vivências do amor. E, quando as tradicionais palavras, em sua forma mais comum, não são suficientes, vem em nosso socorro a poesia. Assim, também temos cartas poéticas, fazendo com que o amor seja dito com outra sonoridade, ganhando rimas, refrões, pautando-se por uma métrica que ensinou que quanto maior o coração, mais amor dará e receberá.

Images of Italian Jewish Emancipation: An Analysis of Family Photographs after the Opening of the Roman Ghetto in 1870
Authors: Barromi-Perlman Edna
Published: April 2024

Abstract: This study analyzes late nineteenth- and early twentieth-century photographs in a family album belonging to Roman Jews. The album was compiled at a crucial moment for Italy and for Italian Jews: after the wake of Italy's national unification. For many Roman Jews the risorgimento and Italian unification in 1870 resulted in liberation from crushing poverty, disease, and abuses under the papal state. These years coincided with the invention and development of photography. This article explores how Jewish emancipation and liberation from ghetto life, alongside the rise of photography, influenced the construction of images and photographic portraits of Roman Jews through the analysis of one family album.

Published: April 2024

Background
To explore the influencing factors of nocturia in benign prostatic hyperplasia (BPH) risk population.
Methods
Data from the National Health and Nutrition Examination Survey (NHANES) between the years 2017 and 2020 were analyzed to explore factors influencing nocturia in BPH risk population. After the inclusion of BPH risk population over 50 years old, the data with incomplete data were excluded, and then univariate logistic regression was used to find the influencing factors for nocturia. Finally, all the influencing factors for nocturia were included for multiple logistic regression. The crucial factors were analyzed by ROC.
Results
A total of 15,560 is managed. Among these, 1754 men are classified as BPH risk group. Depression rating level, history of elevated blood pressure, obesity, daytime sleepy, sleep problems, depression, Leak urine during non-exercise, leak urine before toilet, leak urine during exercise, frequency of urine leakage, age and weekday sleep are found to be associated with nocturia by univariate logistic regression（p < 0.05). Depression rating level, obesity and leak urine before toilet are risk factors for nocturia by multiple logistic regression（p < 0.05). Age(adjusted OR: 1.020, 95% CI 1.006–1.035, p = 0.006), PHQ-9(adjusted OR: 1.100, 95% CI 1.068–1.133, p = 0.000), and BMI(adjusted OR: 1.029 95% CI 1.007–1.052, p = 0.010) as continuous variables are still risk factors for nocturia（p < 0.05). ROC analysis shows that the highest AUX of PHQ-9 is 0.633, frequency of urine leakage 0.571, BMI 0.553, Age 0.549.
Conclusions
The nocturia symptoms of BPH risk population are caused by multiple factors. Among the comprehensive effects of various influencing factors, age, PHQ-9, BMI, frequency of urine leakage play a major role. The most relevant is PHQ-9, that is, the level of depression score.
The significance of wine and the vine in the odyssey, suggestions for new technologies and experiential teaching approaches
Authors: Maria Manola
Published: April 2024

The following study tries to present the multidimensional culture and importance of wine, analyzing examples from the Odyssey as one of the greatest heroic epics of antiquity. Through his epics, Homer deals with important values such as faith, a person's love for the country, as well as the power to overcome difficulties. However, the institution that seems to be of utmost importance, especially in the Odyssey, is that of “filoxenia” (hospitality), since the words “xenos” (foreigner) and "filoxenia” (hospitality) had great value in antiquity. All of the above is highlighted through the events and adventures that take place, with wine having an important place in terms of the development of the plot of the Homeric epic. Education is one of the areas, where New Technologies can be applied, and, therefore, have brought a variety of changes, perspectives and possibilities, both in teaching and learning. Similar efforts have been made to teach the "Odyssey" in schools, as well as use experiential approaches to attract adult cultural tourists.

A study was carried out on the content of oxygen and nitrogen in plasma coatings deposited from Co powder and its alloys (wt. %) Co – 32 Ni – 21 Cr – 8 Al – 0.5 Y, Co – 27.9 Cr – 7.04 Al – 3.25 Si – 2 Y. To do this, we used a conical nozzle attached to the plasma torch, which performs the extraction of the plasma flow after heating and accelerating the sprayed particles. As the power of the plasma jet increases, the content of oxygen and nitrogen in the Co coating increases. When alloying cobalt alloys with Cr, Al, Si, and Y, the oxygen content in the coatings increases less rapidly with increasing plasma jet power, but the nitrogen content in these coatings is higher than in the Co coating due to the interaction of alloying elements with nitrogen. The results for Co-based coatings were analyzed along with their previous data for coatings sprayed from powders based on Fe and Ni. Coatings based on Fe, Co, Ni were divided into four groups according to the mechanism of their interaction with oxygen. The first group includes pure metals, the second includes alloys alloyed with Cr, the third is additionally alloyed with Al, the fourth is alloys with complex alloying of Cr, Mn, C, B, Si with elements that actively interact with oxygen, including the formation of gaseous oxides. Doping with Cr reduces the oxygen content in coatings by 35 – 46 %, additional alloying with Al reduces the oxygen content in the coating by 57 – 78 %, doping with Cr, C, B, Si reduces the oxygen content in the coating by 92 – 95 %. We performed a detailed analysis of the nozzles used for the plasma torch.

The results of structural-phase state investigations of Аl, Al – 12,6 wt. % Si – 0,1 wt. % Fe and Al – 12,6 wt. % Si – 0,5 wt. %  Cu – 2,7 wt. % Mg – 0,3 wt. % Ni – 0,3 wt. % Fe – 0,2 wt. % Mn alloys surface layers alloyed by zirconium atoms under action of compression plasma flows are presented. The formation of metastable compounds Al3Zr with L12 structure and (Al,Si)3Zr with D022 structure in the alloyed layers of aluminum and silumin samples, respectively, was found. Alloying with zirconium atoms makes it possible to increase the microhardness of surface layer in 1.4 – 3 times. Thermal stability of the structure and phase composition of alloyed layers at 550 °C was investigated. The transformation of Al3Zr – L12 into Al3Zr – D023 phase in aluminium and (Al,Si)3Zr disintegration with ZrSi2 in Al – Si alloys was observed during annealing. The formed surface layers had elevated temperature strength.

The influence of the parameters of high-energy, thermal and magnetic-pulse processing on the formation of the phase composition and magnetic properties of nanocrystalline powders of the Fe – O system during their production from cheap problematic iron ore raw materials “blue dust” of the Indian deposit has been studied. The research results showed that the GR-1 concentrate “blue dust” in its properties refers to waste, and not to natural ore material. The presence of an oxide-salt layer on the surface of the particles and the high dispersion of the material do not allow it to be used in its pure form as a feedstock for blast-furnace production, and the development of a processing method requires a separate approach. From the analysis of the results of measuring the magnetic properties, it follows that as a result of the processing of iron ore material in a high-energy planetary ball mill, it was possible to obtain samples with properties characteristic of hard magnetic materials. The particle size is 1 µm and the values of the coercive force and remanent magnetization are 190 Oe and 0.5 kG, respectively. This makes it possible to recommend the use of this magnetic material as fillers for polymer films. The conditions of thermal and magnetic treatment are determined, which make it possible to increase the values of the coercive force by 27 – 35 % and the remanent magnetization by 1.9 – 2.6 times.

The work is aimed to increase mechanical properties of polymers produced by laser stereolithography technology by modifying the composition of photocurable resin (PCR) by highly dispersed filler. A resin based on vinyl ester was developed as an initial one, and aluminum hydroxide was chosen as a filler for it. Adding the filler to the initial PCR leads to a marked increase in the viscosity of the composition at 25 °C. For comparison samples obtained both by laser stereolithography technology and at initiation of polymerization by incoherent UV radiation were simultaneously studied. Thermomechanical analysis of the samples was carried out and the samples were studied by differential scanning calorimetry to determine the thermomechanical characteristics and the degree of conversion of double bonds for these samples. It has been confirmed that the post-treatment of the samples is a necessary step in achieving their high mechanical properties. It is shown that the use of aluminum hydroxide as a FPC filler leads to an increase in the physical-mechanical and thermomechanical properties of cured samples.

The structure of a typical control system for the wire-based electron-beam surfacing process, which is used today for the implementation of additive technologies, is considered, and the main regularities of the process are described. It is shown that the temperature of the underlying layer, which changes during surfacing, is a destabilizing factor affecting the pool temperature and the transverse dimensions of the formed layer. The necessity of using a feedback control system to stabilize the temperature of the deposited layer is substantiated and its technical implementation is described. The results of using the developed prototype of a temperature stabilizer based on a microcontroller are presented, and the fundamental possibility of ensuring the repeatability of the height of the deposited layer and eliminating the separation of the wire from the liquid pool during surfacing of a multilayer cylindrical contour made of 316L steel is shown.

The surface morphology, structure of oxide layers and electrochemical properties in a physiological solution (0.9 wt. % NaCl) of nickel titanium (TiNi) alloy subjected by ion implantation were studied. It was found that an irradiation of the TiNi surface with titanium and niobium ions at an irradiation dose of 1·1017 cm–2 led to the increase of the surface roughness and improvement of corrosion properties. The corrosion performance of ion-beam modified alloy was associated with a higher charge transfer resistance and a lower anodic current. Comparative analysis of the oxide layer structure, performed by transmission electron microscopy, and electrochemical properties revealed that an inhibiting of anodic processes was related with the phase composition and electrical conductivity of the oxide layer. In particular, the ion-beam treatment with niobium resulted in formation of a thin (~ 2 nm) amorphous oxide film onto the TiNi surface, that effectively prevented an oxidation of nickel due to dielectric properties characterized by dielectric constant ε = 44.

The method of scanning electron microscopy and X-ray microanalysis was used to study the morphology and surface composition of cotton lint fibers carbonized by microwave radiation and secondary micro- and nanostructures formed on the surface of the fibers in the process of carbonization. The mass of 3 g of cotton lint treated with 5 at. % H3PO4 solution and having a cylindrical form with transverse notches was used as samples for microwave carbonization. It was shown that impurity elements contained in the initial fibers move during microwave carbonization from the central region of the sample to the marginal zones, where they are deposited on the fibers both as continuous phosphorus-containing coatings and as micro- and nanostructures with different morphology and composition. It was found that the most difficult to remove impurities are P and Ca. On the surfaces of notches of microwave carbonized samples, mainly in the central part, there are areas of deep black color characteristic of activated carbon. It is shown that the carbonized fibers of these areas do not contain impurity elements. Significant differences in the morphology of the fiber surface in this area were found. Four characteristic types of fiber surface structure were revealed. In similar areas of samples without notches, carbonized earlier, the fiber surface always contained a small amount of impurity elements (phosphorus ~ 3 – 6 at. %, calcium ~ 1 – 3 at. %), and the fiber structure was fairly uniform. Secondary carbon structures of various morphologies were found on the surfaces of the cuts: monolithic carbon deposits with a hummocky and platelet structure, thin transparent films (presumably, graphene-like structures), carbon nanofibers and nanotubes (straight and curved, diameter 70 – 150 nm and several microns long). A large variety of structures of carbon products and the absence of impurities in them is due to the high heterogeneity of the process conditions in the slit gap, within which microplasma spots, spark and arc discharges arise.

Published: April 2024

This study aims to conduct a systematic literature review on collaborative learning research in elementary and secondary mathematics education in Korea, explore various characteristics related to the research, and discuss areas for improvement. To achieve this, this study presents a protocol for analyzing research in mathematics education with a focus on collaboration and cooperation, following a systematic literature review methodology. Then analyze the selected studies based on the themes derived from the protocol. As a result of the systematic literature review, research characteristics on collaborative learning were categorized into eight main themes: keywords, small group composition methods, sampling methods, sample size, analysis methods, analytical frameworks, domains of educational goal, and collaborative mathematical competencies in collaborative learning. The research findings revealed several key points: First, many studies conducted at the various school grades and methodologies, help to understand various classroom environments that implement collaborative learning. Second, it was found that the researcher's subjective characteristics were largely reflected in the selection of the sample extraction method and sample size. Third, as the cognitive domain of collaborative learning mainly presents changes as results through pre- and post-academic achievement, in relation to mathematics subject competency, there have been many studies that have derived results in relation to collaborative mathematical problem solving.
The PICRAT model as a tool for analysis of mathematics classes using technology
Authors:   The Korean School Mathematics Society, Lee Jiyeon
Published: April 2024

As teaching and learning using technology has been emphasized, several models have been proposed to explain the integration of technology, and research on technology use has been actively conducted, especially focusing on TPACK. However, by focusing on only the teacher's knowledge, TPACK has limitations in analyzing how technology is used in actual classes and what experiences students have through technology. This study introduces the PICRAT model (Kimmons, Graham, & West (2020)), which focuses on ‘students’ relationship with technology’ and ‘teachers’ teaching practices’, as a lens for analyzing mathematics classes using technology. And by looking examples of analysis of mathematics class design through models, this study explored the applicability of the PICRAT model and its implications for mathematics education and teacher education.

Published: April 2024

There is a prohibition of rotating property on people (Q.S. 59:7) so that the discussion of sharia maqasid on distribution becomes essential to research. This paper aims to know the definition and function of the maqasid of shari'ah in concluding the law. Second, to understand the thoughts of scholars towards maqasid shari'ah. Third, to know the implementation of the shari'ah maqasid on the distribution of property. This article uses a qualitative approach. This article is library research. The results showed that sharia maqasid is an important concept in the study of Islamic law  by paying attention in maintaining faith (din), soul (nafs), mind ('aql), progeny (nasl) and wealth (maal) for humankind. Thoughts of scholars toward sharia maqasid were the main goal (universal value) to be achieved from legal provisions both in general and in particular. Sharia maqasid on the distribution of property creates a turnover of wealth among humans fairly and evenly. Distribution of property can be done through various means including nafaqah, zakat, inheritance, will, waqf, infak, alms, qardul Hasan, feeding the poor, qurban, aqiqah, helping others, fulfilling the rights of neighbours, fulfilling guest rights and Profit, and Loss Sharing (PLS), in addition, the distribution of property can also be done through the delivery of state property to citizens who are considered in need.
