Authors: ÇELİK Fatih , ŞENOL Burcu , DEMİRKIRAN Gökhan , BEK Nilgün , YAKUT Yavuz , YAĞCI Gözde
Published: February 2024

Background Since scoliosis is a three-dimensional deformity, it causes some movement limitations in the spine and related joints. However, functional limitations associated with scoliosis-related hip joint involvement are the subject of research.Aims This study aims to investigate the physical characteristics and functional limitations associated with idiopathic scoliosis (IS), focusing on hip joint.Methods Participants with IS and a control group were assessed using manual goniometry for hip joint RoM, indirect methods for lumbar mobility, the Foot Posture Index (FPI) for foot posture, the Trendelenburg sign within the single leg squat (SLS) test for muscle strength, the Y-Balance test (YBT) for balance, the hip joint position sense (JPS) test for proprioception, and the Lower Extremity Functional Scale (LEFS) for functional status.Results Individuals with scoliosis exhibited limitations in hip joint RoM, particularly in flexion, extension, abduction, adduction, and internal rotation compared to controls.Lumbar mobility was reduced in the scoliosis group. The SLS and Y-Balance tests showed decreased scores in the posterior direction. Scoliosis participants had a tendency towards pronated foot posture. Hip JPS did not differ significantly between the groups. Muscle strength, as indicated by the Trendelenburg sign, was weaker in the scoliosis group. LEFS scores were lower in the scoliosis group but lacked clinical significance.Conclusion However, the observed differences were relatively small and may not have significant clinical implications. Future research should consider specific curve patterns of scoliosis and employ more advanced measurement techniques for enhanced reliability.
A polifonia de professores na fronteira Brasil-Venezuela: Desafios didático-pedagógicos na pandemia do Coronavírus
Authors: Siqueira Evangelista Soares , Hattge Morgana Domênica
Published: February 2024

O presente texto tem por objetivo analisar os desafios didático-pedagógicos vivenciados pelos professores/professoras durante a Pandemia do Coronavírus. Para isso, elegeu-se como lócus da pesquisa a ambiência do Colégio Estadual Militarizado Cícero Vieira Neto (C.E.M.C.V.N.), localizado na cidade de Pacaraima, estado de Roraima. A escolha do Colégio se justifica por sua localização geográfica já que Pacaraima faz fronteira com a cidade venezuelana de Santa Elena de Uairén, além de ter alunos venezuelanos matriculados na referida unidade de ensino. Dessa forma, privilegiou-se a abordagem qualitativa a partir do estudo de caso e do aporte da metodologia da História Oral através de entrevistas semiestruturas. Não obstante, devido à Pandemia do Coronavírus (COVID-19) foi preciso fazer alguns ajustes e traçar algumas estratégias para darmos conta da produção, sistematização e análise dos dados, dentre as estratégias, laçou-se mão para o uso de videochamadas com auxílio do Google Meet, além da aplicação de questionários pelo Google Forms. As estratégias se mostraram satisfatórias no decorrer da investigação porque resguardaram os entrevistados e o entrevistador devido ao sentimento de inseguranças frente ao COVID-19. A partir da pesquisa de campo e das entrevistas é possível inferir que a dinâmica e a singularidade educacional no C.E.M.C.V.N perpassa pelos desafios da barreira linguista que exige busca de alternativas didático-pedagógicas com o intuito de mitigar os obstáculos do e no processo de ensino e aprendizagem. Ademais, os resultados da pesquisa indicam a Fronteira como espaço sociocultural onde existe não somente a circularidade de pessoas, mas também de culturas e diferentes saberes, além dos tensionamentos sociais e culturais, particularmente com o boom migratório de venezuelanos, fugidos da crise no País vizinho, desde 2014.

Os resultados, ainda, possibilitaram identificar que a abordagem macroética é centrada em considerações profissionais mais amplas e relacionadas aos impactos sociais e ambientais decorrentes da realização de projetos e empreendimentos de engenharias. Foi identificada, em adicional, que os contextos nacionais contribuem para a existência de diferentes configurações do modelo de ensino das abordagens micro e macroética em cursos de engenharias. Por fim, a revisão da literatura atestou o maior quantitativo de estudos que relacionavam o enfoque Ciência Tecnologia e Sociedade (CTS) e a Filosofia da Tecnologia à inserção de discussões e conteúdos de caráter macroético nas engenharias.
Seismic reinforcement effect and vibration test of externally attached substructures in a selected Japan school building
Authors: Li Liang , Marusaka Hitoshi , Zhang Yihui
Published: February 2024

In the long-term seismic work in Japan, an effective seismic reinforcement design system and reasonable seismic reinforcement technology have been developed, which is worth learning from. In this paper, the seismic reinforcement of a school building in Japan is taken as an example. Firstly, an overall reinforcement scheme of external prestressed precast concrete (PC) frame and steel brace is proposed. Then, based on the calculation results of seismic reinforcement and the ambient measurement before and after seismic reinforcement, the effectiveness and rationality of the seismic reinforcement method are analyzed. The results show that the seismic reinforcement method of attached substructures changes the original structural system, and solves the problems of excessive deformation and insufficient seismic performance. The reinforcement method improves the story stiffness of the structure, and the vibration period of simple harmonic motion after the implementation of seismic reinforcement is reduced by 0.845 times at most. The research results can provide reference for seismic reinforcement design and performance evaluation of existing school buildings.

Authors: Zhang Yang , Chen Ye , Lu Li-Li , Xie Xiu-Li , Huan Ren , Wu Li-Fang , Tan Li-Na , Xu Tao , Jin Yong
Published: February 2024

Lung cancer is the leading cause of cancer-related deaths worldwide, of
which non-small cell lung cancer (NSCLC) is the most common type, and epidermal
growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) are widely used for the
treatment of NSCLC. EGFR-TKIs are known to develop a drug-resistant response after
a certain number of cycles of dosing, and how to alleviate or even reverse EGFR-TKI resistance
is an urgent problem at present. This review focuses on the role of ncRNAs in
the resistance of NSCLC to EGFR-TKIs and the potential mechanisms underlying the
development of NSCLC resistance to EGFR-TKIs. NcRNAs are involved in NSCLC resistance
to EGFR-TKIs by mediating cellular drug efflux, epithelial-mesenchymal transition,
apoptosis, autophagy, and EGFR mutation. ncRNAs play a crucial role in NSCLC
resistance to EGFR-TKIs. Hopefully, the results will provide some guidance and help
for the treatment and prognosis of NSCLC.

Authors: Berghahn Emílio , Inês Lamb Thainá , Keil Rosana , Oliveira Neves Leonardo de , Granada Camille Eichelberger , Sperotto Raul Antonio
Published: February 2024

Rice is one of the most important cereals, as it feeds over half of the world's
population. Rice production is limited by different abiotic stresses, which would
probably worsen with climate change. Also, we must expect a rapid increase in food
demand. Therefore, there is an urgent need for innovative agricultural technologies able
to increase cereal amounts without increasing arable lands. The inoculation of plant
growth-promoting bacteria (PGPB) from paddy soil can improve plant response to
abiotic stresses; however, the mechanisms involved in such protective response are
largely unknown. The current chapter comprehensively analyses and presents the state-of-the-art inoculation of selected PGPB aiming to improve rice tolerance to abiotic
stress conditions. Different plant responses at the molecular, biochemical,
physiological, and agronomical levels will also be appraised. This summary can
stimulate the producers to inoculate rice plants, contributing to rice production in
abiotic stress-impacted regions.

Authors: Negi Ayushi , Gautam Aarushi , Saini Astha , Pant Manu
Published: February 2024

Actinidia deliciosa, commonly known as Kiwifruit (Chinese gooseberry),
belongs to the family Actinidiaceae. The edible and fleshy fruit has gained popularity
over the past few decades owing to its high nutritive value, and medicinal and potential
curative properties. The fruit is rich in vitamin C, folate, vitamin E, dietary fibers,
antioxidants, enzymes, phytonutrients, etc. The presence of actinide in Kiwis helps in
regulating gastric abnormalities, hypertension, cardiovascular inflammation, hemostatic
disorder, and abnormal glucose metabolism, and prevents cancer. Consequently, the
fruit holds a considerable market value that has led to the establishment of industrial
organizations comprising growers and distributors. For the purpose of fulfilling the
constant market demands, it is crucial to maintain quality standards, timely production,
and an abundance of planting material. This chapter discusses the various in vitro
propagation methods, including diverse and detailed approaches for both the direct and
indirect organogenesis for large-scale production of good-quality kiwi plants, along
with ex vitro hardening and acclimatization processes. It is apparent that the plant
tissue culture techniques can be suitably applied for the mass production of kiwi fruit,
while other in vitro manipulations and further biological research are needed to
improve the field performance and post-harvest life of the fruit and its plant.

Many small and medium-sized enterprises (SMEs) today exploit big data
despite having insufficient resources to do so. The literature is clear that huge
corporations throughout the world are increasingly adopting Big Data Analytics as a
means of gaining a strategic edge. However, the literature shows that SMEs are not
using this technology to its full potential due to factors including a lack of experience
and the associated costs. The goal of this article is to examine the difficulties SMEs
have when utilizing big data in Africa. The study's findings pointed to a lack of
funding, clear information, complicated data, advanced big data analytics tools, reliable
infrastructure, compelling business propositions, clear data privacy and culture norms.
Big data analytics by SMEs help them face and overcome obstacles and reap the
benefits of BD to boost their competitive edge and, ultimately, the economy of their
country and Africa as a whole.

Apontamentos sobre a paragoge no Português Europeu: estudo de caso com base na análise de um dialeto transmontano
Authors: Granja Fábio Barcellos
Published: February 2024

This short paper aims at investigating the causes and contexts that motivate the paragoge phenomenon in European Portuguese. For this end, the phonetic transcription of a speech sample from a Trás-os-Montes’ dialectwas used, illustratingoccurrences and environments in which the phenomenon is observed. The sample was classified according to the dialectal subgroups described by Cintra (1971), and motivators of paragoge, targeted in the present investigation,were outlined. These appear to be related to analogies with the CV syllabic structure, which is especially productive in Portuguese. The results presented here aim at contributing to the initial steps towards a description of paragoge in the investigated dialect.
Imperial Nationalism of Minority Soldiers. Italian-Speaking Tyroleans and Irishmen in the First World War
Authors: Steinbacher Emanuel
Published: February 2024

In the First World War, national minorities fought on all sides. How did these soldiers negotiate their identity as a national minority with their loyalty to and identification with the state for which they fought in the severest war of nations in modern times until then? This paper explores the complex landscape of this question by comparing Irish soldiers in the British Army and Italian-speaking Tyrolean soldiers in the Habsburg forces. Using a sample of war diaries from combatants on both sides and drawing on the more recently upcoming literature on minorities in the First World War, perceptions of these groups about their nationality are examined. The analysis will show how combatants were integrated into a network of loyal relationships to the respective empire through factors such as culture, language and emotions. This is made productive through the analytical category of imperial nationalism. The article emphasises the importance of regiments bridging national identity and imperial loyalty. Italy’s entry into the war (1915) and the Easter Rising (1916) were critical events for soldiers of each side regarding their national self-image. The soldiers’ reactions show the broad spectrum of individual national identity, ranging from increased identification with the Empire to disintegration. Subsequently, both groups increasingly faced discrimination, to which they reacted differently. While the Italian-speaking Tyroleans tended to gradually distance themselves from the Austro-Hungarian Empire, the Irish soldiers mostly maintained their imperial loyalty. These different results illustrate the complex interplay of allegiance, identity and nationality of minority soldiers and the impact of changing circumstances on these factors during the Great War.

A survey conducted by rumah.com showed that a notable number of participants, specifically 37 percent of those aged 22-29 and 36 percent of those aged 30-39, prefer Sharia mortgages to traditional ones. This research aims to explore the willingness of millennials to opt for Islamic housing loans, focusing on how their religious devotion influences this decision. The methodology of this study is quantitative, involving the distribution of questionnaires to 202 millennials. The gathered data underwent analysis using structural equation modeling (SEM-21) and SPSS 25. Findings from the study reveal that both the cost and the individual's earnings significantly encourage millennials to consider Islamic home loans, whereas their level of religious commitment does not play a crucial role. The study concludes that many millennials are inclined towards Sharia mortgages due to the fixed and extended period of repayments. Given their steady income, millennials find purchasing a home more appealing than renting, as owning a home offers a tangible asset that represents savings from their earnings.
Tobacco Smoking or Nicotine Phenotype and Severity of Clinical Presentation at the Emergency Department (SMOPHED): Protocol for a Noninterventional Observational Study
Authors: Campagna Davide , Farsalinos Konstantinos , Costantino Giorgio , Carpinteri Giuseppe , Caponnetto Pasquale , Cucuzza Francesca , Polosa Riccardo ,   SMOPHED Study Group
Published: February 2024

Background

In the last few years, several nicotine products have become available as alternatives to smoking tobacco. While laboratory and limited clinical studies suggest that these devices are less toxic compared to classic tobacco cigarettes, very little is known about their epidemiological impact. Visiting the emergency department (ED) often represents the first or even the only contact of patients with the health care system. Therefore, a study conducted at the ED to assess the impact of these products on health can be reliable and reflect a real-life setting.

Objective

The aim of this noninterventional observational study (SMOPHED study) is to analyze the association between the severity of clinical presentation observed during ED visits among patients using various nicotine products and the subsequent outcomes, specifically hospitalization and mortality.

Methods

Outcomes (hospitalization and mortality in the ED) will be examined in relation to various patterns of nicotine products use. We plan to enroll approximately 2000 participants during triage at the ED. These individuals will be characterized based on their patterns of tobacco and nicotine consumption, identified through a specific questionnaire. This categorization will allow for a detailed analysis of how different usage patterns of nicotine products correlate with the clinical diagnosis made during the ED visits and the consequent outcomes.

Results

Enrollment into the study started in March 2024. We enrolled a total of 901 participants in 1 month (approximately 300 potential participants did not provide the informed consent to participate). The data will be analyzed by a statistician as soon as the database is completed. Full data will be published by December 2024.

Conclusions

There is substantial debate about the harm reduction potential of alternative nicotine products in terms of their smoking-cessation and risk-reduction potential. This study represents an opportunity to document epidemiological data on the link between the use of different types of nicotine products and disease diagnosis and severity during an ED visit, and thus evaluate the harm reduction potential claims for these products.

Authors: Rohana Hana
Published: February 2024

Bioflokulan saat ini menjadi alternatif pengganti flokulan sintetis dalam pengolahan air. Bioflokulan disebut juga sebagai flokulan organik karena dapat dihasilkan dari hewan, tumbuhan, atau mikroorganisme. Dalam penelitian ini akan dikaji kemampuan daun  Abelmoschus manihot L. sebagai flokulan untuk menurunkan turbiditas air. Tahap pertama menentukan parameter optimum pengolahan (derajat keasaman, dosis koagulan dan flokulan, laju dan waktu pengadukan koagulasi dan flokulasi). Tahap kedua mengaplikasikan parameter optimum ke dalam pengolahan secara Jar test (SNI 19-6449-2000). Hasil pengukuran secara triplo diperoleh parameter optimum pengolahan air sebagai berikut: pH 7, dosis koagulan dan flokulan 15 ppm dan 12,5 ppm, laju pengadukan 200 rpm dan 20 rpm dalam waktu 10 menit dan 7,5 menit. Turbiditas air non olahan (awal) rata-rata 78,667 NTU dan air olahan rata-rata 0,835 NTU. Penurunan nilai turbiditas diduga akibat terjadinya destabilisasi partikel koloid secara adsorpsi kimia, sweep floc, dan pembentukan jembatan antar partikel. Hasil uji statistik menunjukkan terdapat perbedaan niai turbiditas yang signifikan pada air olahan diakibatkan oleh penambahan ekstrak daun Abelmoschus manihot L. Simpulan dari penelitian ini adalah daun Abelmoschus manihot L. dapat digunakan sebagai flokulan dalam pengolahan air.

ICH, Intangible cultural heritage, including traditional theatre, traditional handicrafts, oral literature and so on, is a concept put forward by the UNESCO in 2003. Its most fundamental characteristic is its “dynamism”, which often changes with the environment. Variables that influence the inheritance of intangible cultural heritage include inheritors, national policies, laws and regulations, etc. And because there are so many variables, it is often more difficult to protect intangible cultural heritage than tangible cultural heritage. Intangible cultural heritage is an important part of China’s cultural treasury. In recent times, due to the impact of industrial civilisation, some ancient intangible cultures have been faced with problems such as lack of successors and loss of skills. In modern times, the Chinese government pays more attention to the protection of ICH. In this test. This paper will take the national intangible cultural heritage, Jingjiang palm puppetry, as an example to explore the protection and inheritance of China’s localised intangible cultural heritage from two perspectives: the government and the private sector.
Bring the Dual Focus on both Language and Content into ESP Courses through Teacher Collaboration
Authors: Li Renda
Published: February 2024

In China, the evolution from traditional “College English” courses to English for Specific Purpose (ESP) reflects the changing demands for foreign language skills in specialized industries. This transition poses challenges for teachers due to limited specialized knowledge. This study explores the integration of Content and Language Integrated Learning (CLIL) into ESP courses through collaboration between language and content-area teachers. Drawing on a literature review and qualitative research at West Yunnan University of Applied Science, the study examines the challenges traditional English General Purpose (EGP) teachers face in ESP classrooms and their willingness to collaborate with content-area teachers. Results reveal teachers’ struggles with specialized knowledge and materials selection, alongside their openness to collaboration. The discussion emphasizes the importance of fostering cooperation, establishing teaching communities, and utilizing online platforms for enhanced student learning outcomes. This research contributes to the advancement of ESP teaching methodologies by advocating for collaborative approaches that integrate language and content effectively.

With the acceleration of urbanization, more and more construction projects are appearing, and the modern building functions are increasing, while the requirements for project management are also getting higher and higher. In the construction of civil engineering construction, it is necessary to make full preparations, rationally deploy materials, equipment and other resources to ensure the full implementation of construction technology, and further enhance the overall effect of engineering construction. The development of the market economy has promoted the reform of the enterprise management system and the bidding and tendering system. Many projects have made new adjustments in the reform system, leading to a new trend in the management mode of construction projects. It has made significant breakthroughs in management concepts, management strategies and management methods. The new model must bring changes in management. In view of this, this paper focuses on the related problems of civil engineering to improve the current management efficiency. If the quality of the project is not reasonably controlled, it will have a great impact on the economic benefits of the whole project and the development of the construction enterprise.

La pobreza menstrual en la administración pública
Authors: Sandoval Ruiz Diana Fabiola
Published: February 2024

El presente artículo busca realizar un aporte feminista hacia a la Administración Pública ya que se requiere que esta disciplina fomente y abra las puertas a una visión social y humanista hacia las problemáticas feministas ya que esta ha sido una disciplina que se ha quedado con temas centrales y características que regresan a ser un centro burocrático que discute temas de nivel nacional como sería la democracia, la transparencia, la corrupción y ha olvidado el lado social feminista, la parte real y que debería de aportar un beneficio directo a las mujeres y que sea visto como un verdadero recolector de problemas y necesidades de las ciudadanas y ciudadanos. A través de la forma en la que se gestionó la apertura de la agenda sobre la pobreza menstrual se puede observar una gran necesidad de cambio de la estructura de la Administración Pública que necesita tener una perspectiva de género y re pensar desde su estructura para poder abrir el panorama que contemple a las mujeres.
A Review on the Fault-Tolerant Method of PMSM using Finite Element Method by Modifying Phase Angle for EV Applications
Authors: A Abeena
Published: February 2024

Abstract: The present research reviews a fault-tolerant technique for Permanent Magnet Synchronous Motors (PMSMs) that involves phase angle adjustment. Fault tolerance standards for the motor used in electric vehicles are necessary due to the rapid development of these vehicles. The primary option for electric vehicle drive motors is increasingly being replaced with permanent magnet synchronous motors (PMSM), which have minimal torque ripple, great durability, and other benefits. After comparing a six-phase PMSM to a conventional three-phase PMSM, the performance following a phase open is examined. A fault-tolerant technique for modifying the left phase current's phase angle to reduce torque ripple following a phase open is then described. The finite element simulation indicates that the six-phase PMSM's output torque ripple is reduced, and the fault-tolerant technique that is being described can further reduce the torque ripple.

Religion, the faith in God, with all of the spiritual wealth, can influence people and even improve them until perfection. The science of Ushuluddin studies the basics of Islamic religious beliefs (Iman), and all matters related to faith, or Tawhid. The science of monotheism is also called the science of Ushuluddin (the basics or main points of religion) or the Science of Kalam. Therefore it is called the science of Ushuluddin (the matter subject of religion). Ushuluddin has to answered the problem of the Muslim Ummah. The interpretation of Ushuluddin is how the human relationship with God and man to man to avoid inequality, the human beings should be able to put himself as a servant of God are always subjecting themselves stopper form the ritual worship. Religious education aims to help to develop the ability of thinking, to testify values and to have complete knowledge concerning the modern world, to process critical attitude for social values, in order to develop civilization within multicultural society.
