Authors: Rafiansyah Muhammad , Trianasari Nurvita
Published: October 2024

There are several factors behind the research on analyzing the response of social media users, especially on Twitter, to the Ferdy Sambo case. Some of these factors include the increasing use of social media and the widespread adoption of platforms like Twitter in Indonesia to comment on or express opinions about various matters or cases, particularly the Ferdy Sambo case which is the focus of this research. The purpose of this study is to determine how Twitter users respond to the Ferdy Sambo case and to assess the sentiment analysis results from Twitter users based on three categories: positive, negative, and neutral sentiments. Through the utilization of sentiment analysis and text mining, this research aims to uncover commonly used words in comments and responses from Twitter users regarding this case. These frequently used words will then be visualized using word clouds to display both their prevalence and frequency. Based on the analysis conducted, the findings reveal that out of the 15,002 data points, the words or opinions expressed by Twitter users are predominantly negative. These outcomes are further substantiated by accuracy, precision, and recall rates calculated at 97%, 95%, and 90%, respectively. The implications of this study are anticipated to offer insights into the responses of social media users towards a particular case, wherein negative situations generally elicit pessimistic opinions and vice versa. Moreover, it is envisaged that this research could serve as a foundation for future studies on similar subjects or employing similar methodologies.

Published: October 2024

Anomaly detection is widely used in fields like data processing, intrusion detection, and financial fraud prevention, helping to avoid potential accidents and economic losses. In time series anomaly detection, which deals with numerical sequences over time (e.g., urban temperatures, sales data, stock market trends), the Density-Based Spatial Clustering of Applications with Noise (DBSCAN) algorithm is an excellent choice. This paper presents an improved anomaly detection algorithm tailored for seasonal time series data. By combining autocorrelation coefficients with the K-means algorithm, precise clustering results down to the date level are provided, subsequently employing the DBSCAN algorithm for detection, the enhanced algorithm is capable of capturing a greater number of local anomalies. Experiment conducted on daily temperature data from Beijing and Sanya in 2023, the enhanced algorithm exhibited a respective increase of 11.6% and 78% in anomaly detection compared to the original algorithm, thus affirming the feasibility of the approach.

Published: October 2024

A infecção pelo vírus Monkeypox (Mpox) é uma doença caracterizada como uma zoonose que historicamente foi endêmica nas regiões da África Central e Ocidental. No entanto, a partir do ano de 2022, ao serem notificados casos da infecção fora das áreas endêmicas, a Organização Mundial de Saúde (OMS) declarou o surto de Mpox como uma emergência de saúde pública de interesse internacional, fato que perdurou até maio de 2023. Em agosto de 2024, a OMS emitiu uma nova declaração de emergência de saúde pública de importância internacional, motivada pela disseminação de uma variante mais letal e transmissível do vírus. O presente relato tem o objetivo de demonstrar um caso de paciente portador de infecção pelo vírus HIV em estágio de AIDS e imunossupressão avançada, já com diagnóstico de infecções oportunistas e evoluindo com lesões cutâneas compatíveis com infecção pelo vírus Monkeypox.

Published: October 2024

A incidência de fraturas tem aumentado, em parte devido ao envelhecimento populacional. A fratura transtrocanteriana, uma lesão extra-articular, ocorre na área entre o trocanter maior e menor, na transição entre a diáfise e o colo do fêmur. O tratamento cirúrgico ideal deve ser realizado dentro de 48 horas para melhorar o prognóstico e reduzir as taxas de morbimortalidade. Nesta perspectiva, objetivou-se analisar as repercussões clínicas e prognósticas e o tempo médio de espera para a realização do tratamento cirúrgico das fraturas transtrocanterianas de fêmur, dos pacientes admitidos no Serviço de Ortopedia do Hospital de Clínicas Dr. Alberto Lima, em Macapá-Amapá, nos anos de 2020, 2021 e até novembro de 2022. Foram incluídos 49 pacientes submetidos a tratamento cirúrgico das fraturas transtrocanterianas de fêmur, sendo a maioria homens (53,06%), com média de idade de 77,42 (±14,33) anos, pardos (59,18%), solteiros (46,94%), naturais do Amapá (53,06%) e procedentes de Macapá (65,31%). Cerca de 63,27% apresentavam alguma comorbidade, onde as mais prevalentes foram hipertensão (44.90%) e diabetes mellitus (28, 57%). Pode-se observar que 57,14% (IC95%: 42,90 – 71,40) ocorreram no lado esquerdo, por queda de própria altura (81,63%). Para realização do procedimento cirúrgico o tempo médio do trauma para transferência foi de 7,16 dias (±11,52) e do trauma para realização do procedimento cirúrgico foi de 24,41 dias. Concluiu-se que o tempo para a realização dos procedimentos de correção cirúrgica das fraturas transtrocanterianas no HCAL é demasiadamente elevado, necessitando de medidas de intervenção para solucionar essa problemática.

Published: October 2024

Introdução: A Doença de Parkinson é uma condição neurodegenerativa que afeta o movimento e outras funções corporais, resultando na perda de células dopaminérgicas e no acúmulo de α-sinucleína no cérebro. Fatores genéticos e ambientais, além do envelhecimento, contribuem para o desenvolvimento da doença. As pesquisas genéticas globais têm identificado novos loci de risco em populações diversas, ressaltando a importância de abordagens inclusivas. O Parkinsonismo inclui outras condições associadas, como a atrofia de múltiplos sistemas, degeneração cortiço basal e parkinsonismo vascular, com reabilitação multidisciplinar sendo crucial para tratamento. Objetivo: O objetivo deste trabalho foi determinar os impactos de diferentes abordagens na  reabilitação física, psicológica e funcional de pacientes com parkinson ou parkinsonismo. Metodologia: Nesta revisão integrativa, foram realizadas buscas sistemáticas nas bases de dados MEDLINE e SciELO, utilizando descritores estratégicos para direcionar nossa investigação. Os termos-chave incluíram Reabilitação física “Doença de Parkinson”, “Parkinsonismo”, “Terapias complementares”, “Saúde mental” e “Função motora”. Resultados: Os sintomas incluem alterações motoras e cognitivas, com depressão atingindo 38% dos pacientes. Mulheres apresentam maior risco de depressão, associada à mutação GBA1 L444P. A Estimulação Cerebral Profunda (ECP) melhora o equilíbrio, mas os resultados variam entre pacientes. Terapias físicas, como Yoga Mindfulness, mostram benefícios na ansiedade, depressão e qualidade de vida. A reabilitação física e tratamentos psicológicos são cruciais para o manejo dos sintomas e melhora da qualidade de vida.  Discussão: O tratamento multidisciplinar, envolvendo fisioterapia, fonoaudiologia, psicologia e nutrição, busca retardar a progressão da doença e melhorar a qualidade de vida. A Estimulação Cerebral Profunda (ECP) é eficaz para sintomas motores, mas pode ter efeitos psicológicos adversos. A reabilitação física, incluindo exercícios de resistência e práticas como Yoga Mindfulness, mostra benefícios motores e emocionais, destacando a importância de uma abordagem personalizada. Conclusão: A alta prevalência de ansiedade e depressão entre os pacientes reforça a importância da abordagem integrada e da atenção à saúde mental. A Estimulação Cerebral Profunda (ECP) e terapias gênicas, como para a mutação GBA1, são opções promissoras, mas requerem mais estudos. Exercícios físicos e abordagens holísticas, como Yoga Mindfulness, também são eficazes, complementando o tratamento convencional e melhorando a função motora e emocional.

O acidente ofídico causado pelo gênero Bothrops, popularmente conhecido como Jararaca, é o acidente por animal peçonhento maior prevalência no Brasil, sobretudo, na região amazônica. Desse modo, o presente estudo objetivou avaliar a evolução do número de notificações e traçar um perfil epidemiológico das vítimas de acidentes botrópicos na mesorregião do Baixo Amazonas, no estado do Pará/Brasil, compreendendo os períodos de 2013 a 2022. Os dados foram obtidos pela plataforma SINAN/DATASUS, disponibilizados gratuitamente pelo ministério da Saúde. Ao longo destes 10 anos, foram notificados 6291 casos, com uma forte tendência de aumento de ocorrência dos acidentes, especialmente entre 2016 e 2021 onde se identificou um aumento de 74% de notificações, a microrregião mais afetada foi a de Santarém com 52,5% dos casos, e os meses caracterizados por maior precipitação foram aqueles que registraram o maior número de notificações. Entre as vítimas, 79,54% eram homens; 86,08% pardos; 61,29% pertenciam a faixa etária entre 20 e 59 anos; 49,93% apresentavam ensino fundamental incompleto; 72,83% tiveram um tempo de atendimento menor que 6 horas e apenas 4,9% dos casos foram considerados graves, o que reflete uma baixa taxa de mortalidade de apenas 0,46%. Constatou-se, portanto, que o acidente botrópico está diretamente relacionado com fatores geográficos, climáticos e ocupacionais da região, afetando, principalmente, homens pardos em idade economicamente ativa, com baixo nível de escolaridade e que trabalham em regiões de mata, região ocupacional muito comum no Baixo Amazonas.

O clareamento dental tem apresentado destaque dentre os procedimentos odontológicos estéticos por ser minimamente invasivo e pela sua eficácia, entretanto este pode gerar alguns efeitos deletérios nas estruturas dentárias e materiais restauradores, dentre eles alterações na rugosidade superfial. Desta forma, este estudo buscou avaliar os efeitos dos peróxidos de hidrogênio (PH) e carbamida (PC) em altas concentrações sobre a rugosidade superficial de dois tipos de resina composta, sendo uma delas livre de Bisfenol-A (BPA) em sua formulação. Para isto, foram confeccionadas 30 amostras da resina microhíbrida Opallis® (FGM) e 30 da nanoparticulada Vittra APS® (FGM). Dois agentes clareadores foram usados, um contendo PH a 35% e outro PC a 37%, ambos simulando a técnica de clareamento dental de consultório. As amostras foram submetidas à leitura do rugosímetro para determinar a rugosidade superficial média (Ra) inicial e após o uso dos agentes clareadores. Com isto, foi observado que a resina composta Opallis® apresentou aumento significativo na sua rugosidade superficial (p<0,01) quando submetida à ação dos diferentes agentes clareadores. Além disso, o PH a 35% foi capaz de provocar efeitos deletérios mais acentuados na superfície da resina microhíbrida comparada a nanoparticulada. Assim, foi possível concluir que o PH a 35% e o PC a 37% promoveram aumento significativo da rugosidade superficial da resina composta microhíbrida Opallis®, porém não alteraram a superfície da resina composta nanoparticulada Vittra APS®, possivelmente por esta possuir um complexo de sílica-zircônia na composição e ausência de BPA na sua matriz orgânica.

Published: October 2024

O estudo das comunidades microbianas intestinais enfatiza as bactérias (microbiota), enquanto negligencia os fungos intestinais devido à sua menor abundância (0,01–0,1% do microbioma intestinal). Aos fungos que colonizam o intestino humano é dado o nome de micobiota intestinal humana (MIH). A existência dessa comunidade fúngica pode trazer diversos benefícios para o hospedeiro, contudo, também pode trazer contribuições negativas ao hospedeiro, como causar infecções oportunísticas e produzir micotoxinas. Neste contexto, o objetivo principal do estudo foi revisar a literatura em relação aos impactos da MIH na saúde e na doença, sua composição e fatores que a modificam. Foi realizada uma revisão integrativa da literatura sobre o tema, a partir da consultada a base de dados Medical Publications (PubMed) e seleção de 12 artigos para escrita do trabalho, publicados entre 2013 a 2023. Semelhante às comunidades bacterianas em humanos, as comunidades fúngicas podem ser encontradas em diferentes locais anatômicos do corpo humano, como pulmões, vagina, pele, cavidade oral e trato gastrointestinal. Em indivíduos saudáveis, é comumente encontrado fungos dos filos Ascomycota, Basidiomycota e Mucorimycota e dos gêneros Aspergillus, Candida, Debaryomyces, Malassezia, Penicillium, Pichia e Saccharomyces. A MIH é flutuante e influenciada por vários fatores, de acordo com o hospedeiro e seus hábitos, estando relacionada com diversas condições de saúde, bem como proteção da barreira intestinal e, com isso, prevenção de doenças. Portanto, a MIH se mostra como um campo ainda obscuro dentro da medicina, mas que pode oferecer tanto condições para o entendimento de doenças complexas como a promoção de saúde.

Os caninos desempenham um papel fundamental na arcada dentária, garantindo a harmonia oclusal do paciente. Consideram-se dentes impactados aqueles que, devido a qualquer barreira física, alteram seu processo fisiológico na erupção dentária, sendo este problema mais prevalente em mulheres, onde a região palatina é mais afetada. Anamnese, exame clínico e exames de imagem são cruciais para identificar e especificar a localização de um dente impactado. Quanto mais cedo o diagnóstico for realizado, melhor será o prognóstico do caso. Existem várias abordagens terapêuticas, cada uma com sua própria recomendação. Embora trazer de volta a função dos caninos impactados apresente alguns desafios, a falta de tratamento pode resultar em complicações, incluindo reabsorção radicular, anquilose e até neoplasias. O objetivo do presente estudo é ter o conhecimento de uma forma geral sobre a impactação de canino, incluindo as técnicas cirúrgicas disponíveis, os tratamentos a longo prazo, individualizando cada caso em específico e o prognóstico ideal para cada caso. A partir dessa revisão, é possível concluir que dependendo da posição do canino e da detecção precoce através de diagnósticos precisos e tratamento interdisciplinar o sucesso de cada caso clínico é estabelecido.
Mr. Tumbles’ Maya and the Multiplicity of Personas: Leveraging Illusion and Reality in Educational Game Design for SEN Language Learners
Authors: Namburi Subhangi
Published: October 2024

Educational research for Special Educational Needs (SEN) students has increasingly recognised the necessity for tailored approaches that accommodate diverse learning needs. Despite advancements, there remains a significant gap in the development of digital interventions, particularly video games, that cater to the language acquisition and communicative needs of SEN learners. This study explores how psychological paradigms from the popular children's television show ‘Mr. Tumble’ (made specifically for children with special educational needs) can inform the creation of language learning video games. By analysing the use of ‘Makaton’ a multimodal communication tool that combines signs, symbols, and speech the study highlights the potential of integrating similar techniques into game design to enhance accessibility and engagement for SEN learners. The philosophical understanding of Maya, which emphasises the illusory nature of multiplicity, serves as a theoretical framework to understand how a single character can embody multiple roles within a game, providing a consistent yet diverse learning experience. This approach not only aids in language comprehension but also fosters emotional and social development through relatable Non-Player Characters (NPCs) designed to interact meaningfully with learners. The study posits that incorporating these elements can create immersive, emotionally resonant educational experiences and the development of parasocial relationship between the learner and the digital intervention, that better meet the needs of SEN students, ultimately leading to more inclusive and effective language learning environments. Children simultaneously navigate multiple roles and perspectives, each reflecting a different aspect of reality in make-believe play. The critical importance of integrating this cognitive theoretical framework similar to that into the design of NPCs in educational video games is highlighted in this research. The paper argues that the paradigms of ‘multiplicity of mirrors’, when effectively incorporated into NPC design, can reflect different aspects of language, culture, and social interaction, offering learners a more immersive and multifaceted learning experience.

Published: October 2024

This communication is a theoretical organic chemistry study on the interaction of uric acid with ammonium molybdate in acidic medium (Gigli test for uric acid). Colour tests give rapid, visible, results. However, it is interesting know what is happening in the test tube at molecular level. In the present paper we describe the reaction route of the above mentioned assay. Each step is fully commented and the electron flow is also given. The key stages are: addition of molybdic acid to the C-C double bond, acidolysis of the organometallic ester with reduction to molybdenum (IV) and epoxide formation (oxidation step). Ring opening of the oxirane and reaction with water. A glycol is formed followed by opening of the five-member ring giving a carbonyl and an ureido chain. Finally, elimination of urea gives rise to 2,4,5,6-tetraoxo-hexahydropyrimidine (alloxan) which is hydrated. The blue colour observed (molybdenum blue) is a mixture of several oxides.

An Experiment to Test a New Theory in Physics, Fundamentally Different From General Relativity, by Changing the Speed of Light in Electromagnetic Interaction
Authors: Vegt Wim
Published: October 2024

The fundamental foundation for Einstein’s Theory of General Relativity is the “Curvature of Space and Time” due to a Gravitational Field. In the “Theory o f General Relativity” Gravitational RedShift has been explained by a change in time and space resulting is a change in the observed frequency shift in the spectrum o f the light being emitted by far away Galaxies. The foundation for Einstein’s theory o f General Relativity is a constant value for the speed o f light in the absence of a gravitational field.
In the “New Theory” the fundamental foundation is “Equilibrium”. Equilibrium for the “5 fundamental force densities in light” in any direction at any time and at any location. The New Theory describes a changing in the speed of light when corresponding monochromatic beams of light (highly coherent LASER beams) cross each other in different directions which effect would be in contradiction with the fundamental assumption in General Relativity of a constant speed of light. This experiment will be a deter mining test for the New Theory in Physics.
Astrophysics of Shadows: The Dead Universe Theory — An Alternative Perspective On The Genesis of the Universe
Authors: Almeida Joel
Published: October 2024

This article presents the theory of the "dead universe" as a new perspective on the origin and evolution of the cosmos. It proposes that our universe may have emerged from remnants of a previous universe, vastly larger than the observable universe, which collapsed and perished, transforming into a defunct entity whose laws still influence our cosmos. Furthermore, the theory suggests a second hypothesis, in which this universe, from its very creation, has always been immersed in a state of death—not in the traditional sense of stellar death, but as a primordial existence characterized by the total absence of light. In this chaotic context, light, which was not an intrinsic quality of this universe, emerged as a cosmic anomaly, culminating in the formation of the observable universe, which now resides at the center of a black hole belonging to the dead universe.

Published: October 2024

One of the major problems faced by many restaurants in Nigeria is high operational cost resulting from high cost of energy, food ingredients and waste disposal. Indiscriminate disposal of food wastes contribute to environmental problems such as global warming and the spread of diseases. This paper presents the design and fabrication of a biogas plant for the conversion of biodegradable food wastes into biogas and agri-supplements which can be used for domestic and commercial purposes such as cooking/heating and agricultural applications respectively. This study is geared towards the domestication of an existing technology that has not been taken seriously in Nigeria. the anaerobic digester consists mainly of the slurry inlet, the digester, gas holder and effluent discharge pipe. The slurry, a mixture of food waste and water was fed in to the digester and allowed to digest anaerobically to generate biogas consisting mainly of methane. The digestate, a harmless solid/liquid mixturewas applied as organic manure to a small portion of land in an agricultural experiment.Results of combustion tests in a locally fabricated torch presented a long, blue and quite flame, similar to that of LPG. Digested fed crops grew faster and yielded better. This projecthas the potential to enhance the operational sustainability of restaurants by lowering the cost of cooking and heating, while also supplementing vegetable supply.

Authors: R.Adeshina Adebimpe , A.Olaniyi Fatoye
Published: October 2024

The study focus on the characterisation of the tailings attributes with a view to understanding the geotechnical properties, leaching potential and possible major oxides. The samples were composited into five. The composited samples were subjected to both physical and chemical tests. The physical tests include particle size distribution, specific gravity, density, residual humidity and Atterberg limits. The chemical tests include pH, organic matter, and Energy Dispersive X-Ray Fluorescence Spectrometry (ED-XRFS). Mineralogical analyses were also carried out on the composited samples using the Scanning Electron Microscopy (SEM) coupled with Energy Dispersive X-ray Spectroscopy (SEM-EDX). The results from the physical tests show that the tailings are mostly fine-medium sands, having high specific gravity and bulk density, with low residual humidity. The chemical analyses show that the tailings are weakly acidic and neutral with low organic matter. The energy dispersive x-ray fluorescence spectroscopy analysis of the samples shows that they contain high concentrations of Fe2O3, SiO2, and other trace compounds. The Fe2O3 of the samples ranged from 15.03 to 20.12% and SiO2 ranged from 57.26 to 60.10%. SEM micrographs obtained revealed the interlocking nature of the minerals constituting the ore matrix. EDX analysis of the regions within the ore matrix revealed the presence of Si, Fe, Al, K, Ca, Nb, Y, Ag, Zn, Mg, Cl, P, S, Na, Ti, Zr; such that silicon and iron are the major elemental constituents of the ore matrix while other elements exists in trace form.

Authors: Chukwu Matthew , Tola Riches John
Published: October 2024

The essence of this study is to proffer solution on the degradation of the environment caused by non-degradable plastics waste. A novel approach on plastic waste management was adopted by fabricating a thermoplastic natural rubber (TPNR) composite using waste Polyethyleneterephthalate {PET}plastics and eggshell as biofillers to initiate degradation by microorganism.Waste Polyethylene Terephthalates (PET) was grinded andmelted blended with Natural Rubber with 40pphr of Eggshell to fabricate a Natural Rubber Thermoplastic elastomer (TPNR) composite. The resultant thermoplastic elastomer composite was prepared for soil burial for a period of 90 days to obtain percentage weight loss as an indication of biodegradation. The NR/PET composite was evaluated for tensile properties. The results obtained were of the new that the tensile strength, elongation at break and modulus decreases with increase in soil burial duration time. The eggshell as a biopolymer has been shown to initiate biodegradation. There was a reduction in tensile strength at a blend ratio of 50/50 NR/PET blend, an indication that degradation has occurred, hence tensile properties are useful tools for the evaluationof biodegradation of polymeric materials

Published: October 2024

Access to clean and safe drinking water remains a critical challenge, particularly in low- and middle-income countries. This study focused on the development of a point-of-use household water purification system utilizing locally sourced clay material. The clay, collected from Imiegba in Edo State, Nigeria, was molded into ceramic filters and fired to create a porous structure essential for filtration. The system's effectiveness was evaluated by testing water from the Omouku River before and after filtration, with analyses conducted for physicochemical parameters, heavy metals, and microbial contaminants. Results indicated significant improvements in water quality, including the complete elimination of heterotrophic bacteria and reductions in heavy metal concentrations. The study underscores the potential of locally available materials in providing a sustainable and affordable solution for improving access to safe drinking water in regions with limited resources. Recommendations include regular monitoring, community education, and further research to optimize the filtration system's performance.

Authors: Raza Mohd Mohsin , Singh Yogendra
Published: October 2024

The Pirpanjal range, nestled within the Himalayan region, confronts substantial soil erosion challenges owing to its diverse topography and the inherent instability of geological formations. This study focuses on the Rajouri region, to assess soil erosion susceptibility and spatially prioritize vulnerable zones. Utilizing a Geographical Information System (GIS)-based approach, we employed the Analytic Hierarchy Process (AHP) and the Weighted Sum Method (WSM). Various datasets, including precipitation records, geological maps, soil maps, and satellite imagery, were incorporated to derive eleven critical factors. These factors encompassed topographical derivatives; land use and land cover (LULC), soil properties, drainage patterns, rainfall data, lithological characteristics, wetness index, and the vegetative health of the area. The methodology employed yielded unbiased and reliable ratings and weightages, as substantiated by a Consistency Ratio (CR) of 0.095. The results reveal that 41% of the total area in the study region is exceedingly vulnerable to soil erosion. Slope variations range from 0 to 67.14 degrees, delineating high and very high susceptibility zones spanning 531.79 km² (19.82%) and 316.20 km² (11.78%) of the area, respectively. Additionally, assessments based on the Normalized Difference Vegetation Index (NDVI) and Normalized Difference Water Index (NDWI) underscore the severity of soil erosion, covering 40% and 25% of the highly susceptible zones, respectively. High drainage density and curvature zones were identified in 13% and 31% of the study area, respectively. This comprehensive study contributes valuable insights for the planning and implementation of effective soil conservation measures in the Rajouri region.

This study uses Charmaz's (2006) constructivist grounded theory to examine how small enterprises dynamically connect IT adoption with business goals. To explore small company IT alignment practices, the research uses a qualitative approach to conduct in-depth interpretive interviews with 31 owner-managers. The study methodically analyses grounded data to find processes and concept interrelationships, examining contextual elements, actions, reactions, repercussions, and results. This analysis creates a new framework for business-IT alignment: adaptation, anticipation, synchronisation, and collaboration. Each state shows how small enterprises balance technological and commercial goals, presenting a detailed view of how they do so. This reactive alignment method allows small enterprises to adapt their IT plans to external changes or business needs. Anticipation is a proactive alignment strategy that positions organisations to strategically harness technological advances by anticipating future business and IT needs. Synchronisation occurs when IT and business strategy match in real time, harmonising IT systems and business operations. Collaboration involves deeper integration where IT and business goals are co-created through communication and cooperation. The study's methodology helps policymakers, researchers, and small firm owner-managers predict and analyse business-IT alignment behaviours. This methodology diagnoses alignment states and improves IT adoption strategies and business objectives-IT integration. These findings are important for IT-business alignment theories, especially in small enterprises with resource restrictions and unpredictable contexts.
“A Study on Process Costing Techniques & Its Effectiveness”
Authors: A Soudatti Dr. Manjula
Published: October 2024

This study investigates the various process costing techniques employed in manufacturing and service industries and assesses their effectiveness in cost management and financial reporting. Process costing, a method that accumulates costs for each process or stage of production, is pivotal for organizations aiming to optimize resource allocation and pricing strategies. The research explores traditional and modern techniques, including weighted average, first-in-first-out (FIFO), and activity-based costing (ABC), to understand their impact on cost accuracy and decision-making. By analyzing case studies and industry data, this study identifies the strengths and limitations of each technique. The findings suggest that while traditional methods offer simplicity and ease of implementation, modern techniques provide greater accuracy and insights, particularly in complex production environments. The effectiveness of these techniques is evaluated based on criteria such as cost control, financial transparency, and managerial decision support. The study concludes that a hybrid approach, integrating aspects of different techniques, often yields the most comprehensive results. Recommendations are provided for organizations seeking to enhance their cost management practices through the strategic application of process costing techniques.

Authors: Chen Dongyan , Sun Baixuan , Gao Pengbin
Published: October 2024

In recent years, science and technology business incubators have gradually expanded in scale and number. However, in the process of operation, there are many problems, such as improper utilization of resources, different levels of services, and varying quality of services and shared resources, which constitute a serious challenge to the development of science and technology business incubators. In this paper, based on the DEA method and the Malmquist index method, the science and technology business incubators in 29 provinces and regions in China from 2019-2023 were selected as samples. The K-means cluster analysis was used to make an inter-regional analysis of incubator variability, and at the same time, the incubators were subjected to a geographic area variability analysis based on the classification of the four major economic regions. The results show that the operational efficiency of China's science and technology business incubators performed well in 2019-2023 as a whole, but there are still problems, such as redundant inputs and insufficient outputs in individual regions. Combined with the incubator efficiency influencing factors, the research in this paper will be synthesized to make targeted countermeasures and suggestions on practices to improve the operational efficiency of incubators.

Effect of Oil Bean Husk Ash (OBHA) and Breadfruit Husk Ash (BHA) on the Compressive strength. and Heat of Hydration of concreate: A review
Authors: Abdulmuminu Anefi Yusuf
Published: October 2024

This review investigates the use of Oil Bean Husk Ash (OBHA) and Breadfruit Husk Ash (BHA) as partial substitutes for Ordinary Portland Cement (OPC) in concrete. The primary focus is to assess how these agricultural waste materials influence the compressive strength and heat of hydration of concrete. The study analyzes various research findings on concrete mixes incorporating OBHA and BHA, with different proportions (0%, 5%, 10%, 15%, 20%, and 25% by weight) of these ashes. Techniques such as X-ray fluorescence (XRF) have been employed for raw material characterization, ensuring adherence to established standards. Key properties examined include compressive strength and heat of hydration after standard curing periods. The review highlights that the inclusion of 15-20 wt.% OBHA or BHA generally enhances the compressive strength of concrete, with OBHA often showing superior performance compared to BHA. The impact on heat of hydration is also discussed, revealing insights into the thermal behavior of concrete with these waste materials. The findings suggest that both OBHA and BHA can significantly improve the performance of OPC-based concrete, offering potential benefits for sustainable construction practices.

Tutees' Bullying Experiences in Employment of Pair Tutoring: A View from Grade Two Pupils
Authors: Jaminal Margarita V.
Published: October 2024

Bullies can victimize others in a multitude of ways. While some are hidden and private, others are obvious and public. Bullying in schools frequently takes place in unstructured learning environments. Direct bullying combines verbal and physical abuse. Verbal bullying occurs when a pupil is the target of remarks made aloud or information written that harms their feelings. This exploratory research study was to identify the experiences of bullying by tutees.The research sample comprised fifteen tutees at the Division of Misamis Oriental at the Tagoloan Central School, Philippines. Using the qualitative approach with an exploratory research design, the fifteen grade two tutees who experienced bullying inside the classroom during pair tutoring sessions were considered participants through purposively sampled selection. There was the utilization of in-depth interviews in the data gathering. The study adhered to ethical principles during the conduct. It strictly followed the components of trustworthiness: credibility, dependability, transferability, and conformability to review the validity of the qualitative data. The study revealed that during pair tutoring, tutees experienced verbal bullying- the tutor to the tutee as the tutor constantly uses mean remarks, such as You are dull. Relationship bullying to the tutee as the tutor becomes bossy and short-tempered by letting tutees learn quickly. Physical bullying to the tutee as the tutor eventually hits the tutee if the tutee cannot learn quickly. Along with the insights, the study emphasized that teachers must closely monitor by observing tutor behavior and words they utter during pair torturing sessions and select and train tutors; training should cover tutor roles and responsibilities so that bullying will not occur during pair tutoring sessions and bullying is an issue in education that needs to be solved to ensure pupils good learning outcomes by a safe learning environment. Bullying affects children's academic achievement because it makes them afraid to stand out and pursue their learning desires. Every teacher should work to stop bullying in the classroom by integrating anti-bullying policies and discipline into classroom discipline.
