Społeczno-kulturowy wymiar przestrzeni wiejskiej
Authors: Wójcik Marcin
Published: May 2024

Idea tej pracy zrodziła się m.in. w wyniku zainteresowania dyskusją o specyfice badawczej geografii człowieka, zwłaszcza we współczesnych uwarunkowaniach instytucjonalnych, oraz jako potrzeba poszukiwania alternatywy dla panujących powszechnie tendencji dezintegracyjnych w naukach społecznych. W związku z tym, podjęto próbę określenia pola przedmiotowego geografii człowieka, wskazując – jako kluczowe – koncepcje i modele przestrzeni, na które można spojrzeć w kontekście różnych form zamieszkiwania ludzi, ich zmiany w czasie oraz w odniesieniu do przemian cywilizacyjnych. W tym przypadku są to nawarstwiające się w czasie ujęcia teoretyczno-metodologiczne, które można odnieść do trzech zasadniczych typów analizy zjawisk w przestrzeni wyróżnionych przez M. Foucaulta, tj. umiejscowienia, rozciągłości i usytuowania. Poszczególne rozdziały, które odpowiadają trzem przypadkom badan nad osadnictwem wiejskim, prezentują kwestie odnoszące się do wyjaśnienia relacji człowieka z przestrzenią rozumianą jako podłoże jego egzystencji (ziemia). We wszystkich badaniach przeplatają się trzy kluczowe dla geografii człowieka kwestie, tj. problemy określenia stanu i przekształceń krajobrazu kulturowego, tożsamości terytorialnej oraz miejsca człowieka i społeczności lokalnych w przestrzeni. W pracy oceniono możliwości poznawcze przedstawionej problematyki badawczej oraz ich rolę w kształtowaniu podstaw odrębności teoretyczno-metodologicznej geografii człowieka. Wskazano również podstawowe kwestie dotyczące przemian społeczno-kulturowych przestrzeni wiejskiej. Jest to o tyle istotne, że wieś podlega bardzo istotnym przekształceniom, co w tym zakresie wpływa na jej inne cechy osadnicze, zwłaszcza fizjonomiczne i funkcjonalne.
Internet Addiction on Psycho-Social Symptoms of Happiness and Aggression through Difficulties in Emotion Regulation: Evidence Following COVID-19 Pandemic
Authors: Kavaklı Mehmet , Yalçın Süleyman Barbaros , Coşkun Muhammet
Published: May 2024

Background: Internet usage has increased during the pandemic. The aim of this study is to examine the relationship between internet addiction (IA), happiness, and aggression in the context of difficulties in emotion regulation (DER). The psycho-social symptoms of the COVID-19 pandemic appear to be more persistent over time compared to its physical symptoms, especially regarding Internet addiction in the young population. This study seeks to understand these effects on happiness and aggression through difficulties in emotion regulation. Participants and Procedure: The sample of this study consisted of 325 university students. Data were gathered using the Young Internet Addiction Scale Short Form, Oxford Happiness Scale Short-Form, Difficulties in Emotion Regulation Scale Brief-Form, and Buss-Perry Aggression Questionnaire. Results: The results showed that internet addiction was negatively related to happiness, and this relationship was mediated by difficulties in emotion regulation. Similarly, internet addiction was positively related to aggression, and this relationship was fully mediated by difficulties in emotion regulation as well. Conclusion: These research findings emphasize the need for creating effective interventions to enhance emotion regulation skills in internet-addicted adults. The results are discussed in light of the effects of the coronavirus pandemic.
Latent structure and measurement invariance by gender of the Embodied Image Scale
Authors: Volarov Marija , Janičić Bojan , Popov Stanislava , Barzut Vesna
Published: May 2024

Body image is a multidimensional construct that includes both aesthetic (how our body looks) and functional components (what our body can do physically). Our study aimed to investigate latent structure and measurement invariance (MI) by gender of the Serbian translation of Embodied Image Scale using a large sample of adults from the general population (N = 1035; M = 26.33, SD = 9.94; 66.7% females). The Embodied Image Scale (EIS) incorporates aesthetic and functional body image. According to the results of the confirmatory factor analysis, the following five factors described the latent structure of the EIS the best: functional investment (FI), functional values (FV), functional satisfaction (FS), aesthetic satisfaction (AS), and aesthetic values and investment (AVI). The results of the MI suggested that the EIS achieved the strict (residual) level of invariance. In addition, the convergent validity of the EIS was tested by correlating the EIS scores with positive and negative mental health indicators. The results suggested that FV, FI, FS, and AS had a positive correlation with positive affect and unconditional self-acceptance (USA), FS and AS correlated negatively with negative affect (NA), symptoms of depression (D), and conditional self-acceptance (CSA), while the AVI had a positive correlation with NA, CSA, D, and negative correlation with USA. Finally, we compared physically inactive participants, recreationists, and active athletes on the EIS scores. The results revealed that all groups differed in FV, FS, and AS in a way that scores on these subscales increased with increased physical activity.
The effects of resilience and basic personality traits on subjective well-being in elderly
Authors: Petrović Jelica , Kovač Lila , Dinić Bojana M.
Published: May 2024

The aim of this research was to examine the prediction of aspects of subjective well-being based on resilience and seven basic personality traits in users of gerontological centers, and the incremental contribution of basic personality traits in explaining adaptation to old age, beyond the variance explained by resilience. The sample consisted of 151 participants (54.3% female) with an average age of 80 years. Satisfaction with life, as cognitive indicator, and emotional distress (anxiety, depression, and stress) were used as indicators of subjective well-being. The results showed that resilience, neuroticism (in the negative direction) and positive valence predicted life satisfaction in the elderly. In predicting emotional distress, neuroticism stood out as a key predictor, while the significant contribution of resilience is dimnished by introducing personality traits into the model. The results provide a more complete picture of the relationships between resilience, personality traiits, and subjective well-being in a sample of the elderly in Serbia, and confirm the importance of studying these relationships from a developmental perspective.

A Day in the Cornfields: A Western Otomi Narrative
Authors: De la Cruz-Sánchez Gabriela , De la Cruz Claudio
Published: May 2024

This paper focuses on Western Otomi, a Mexican native language spoken in the municipality of Temoaya in the State of Mexico (ISO 639-3 ott). Speakers recognize themselves as dri ñatho, which means ‘I still speak’ and differentiate themselves from people who only speak Spanish, even though they belong to the same community, as i ñamfo ‘they speak Spanish’. This variety is underdocumented, mainly transmitted by oral tradition and spoken at home or with friends and neighbors. Hence, receptive speakers are common. Through this narrative from a Western Otomi speaker, we are offered a glimpse into what a day in the cornfields is like. In addition, this narrative gives us general insight into some features of the language. So, after introducing the cultural context of it, I present the narrative.

Authors: Prado Eliane Mimesse
Published: May 2024

A cidade de São Paulo necessitava nacionalizar as crianças, ensinando a língua portuguesa. Objetiva-se explicitar as ações do governo estadual nesta empreitada. As escolas elementares subsidiadas existiram em todas as colônias de emigrados italianos pelo mundo, verificou-se um intercâmbio entre os imigrantes. Como o Reino da Itália havia se unificado no século XIX, o governo criava e mantinha escolas privadas nas colônias, visando a formação do cidadão italiano no exterior. As escolas subsidiadas ensinavam a língua italiana instituída oficialmente após a unificação. Foram poucos os professores que lecionaram em São Paulo que eram formados por Escolas Normais, o amplo número de alunos contribuiu para a existência de professores leigos. A metodologia foi embasada na pesquisa documental e bibliográfica. Como fontes primárias foram usados o periódico Fanfulla, o delle Scuole Italiane all’estero Governative e Sussidiative e o Annuario de Ensino do Estado de São Paulo, legislação. A base documental utilizou Certeau (2002), Salvetti (1995), Rolnik (1999), entre outros. As escolas públicas não ofereciam vagas suficientes. Concluiu-se que o governo encontrou formas de expandir as vagas escolares, para formar efetivamente o cidadão brasileiro.
The Gut and the Translocated Microbiomes in HIV Infection: Current Concepts and Future Avenues
Authors: Nganou-Makamdop Krystelle , Douek Daniel C.
Published: May 2024

It is widely acknowledged that HIV infection results in disruption of the gut’s mucosal integrity partly due a profound loss of gastrointestinal CD4+ T cells that are targets of the virus. In addition, systemic inflammation and immune activation that drive disease pathogenesis are reduced but not normalized by antiretroviral therapy (ART). It has long been postulated that through the process of microbial translocation, the gut microbiome acts as a key driver of systemic inflammation and immune recovery in HIV infection. As such, many studies have aimed at characterizing the gut microbiota in order to unravel its influence in people with HIV and have reported an association between various bacterial taxa and inflammation. This review assesses both contradictory and consistent findings among several studies in order to clarify the overall mechanisms by which the gut microbiota in adults may influence immune recovery in HIV infection. Independently of the gut microbiome, observations made from analysis of microbial products in the blood provide direct insight into how the translocated microbiome may drive immune recovery. To help better understand strengths and limitations of the findings reported, this review also highlights the numerous factors that can influence microbiome studies, be they experimental methodologies, and host-intrinsic or host-extrinsic factors. Altogether, a fuller understanding of the interplay between the gut microbiome and immunity in HIV infection may contribute to preventive and therapeutic approaches.

The research aims to untangle the different court decision in firstinstance of religious courts in West Sumatra regarding past spousal support(nafkah madhiah) to former wife. Such unified decisions bring about negligenceof wife’s and children’s right of support. This research uses the religiouscourt archives on past spousal support as the main data. The judge decisionand its reason, pattern of logic and type of protection are critically analyzedin relation to the existing regulation and law. There are a huge number ofhusbands who ignore and leave their wives and children without financialsupport. They repudiate their wives and propose the petition to court. Whenappearing at court to respond the petition, women usually reclaim spousalsupport if the petition will be granted. However, judges often respond to suchwomen’s claim differently. Judge may approve women’s demand while othersreject them. As a result, wives and children face the most critical situationupon court decision. It is therefore urgent to offer legal aid and protection ofwomen and their children in a post-repudiation court decision.

Modeling carbon dioxide emissions in power plants: a perspective on smart cities and low-carbon economy
Authors: Qamber Isa S.
Published: May 2024

Electricity power plants are the primary source of carbon dioxide (CO2) production. The combustion of fossil fuels in these power plants releases CO2 and other greenhouse gases (GHGs) into the atmosphere. Emissions of CO2 and other GHGs occur throughout the life cycle of electricity generation technologies, including extraction, processing, transportation, and combustion of fossil fuels. Nowadays, the development of smart cities plays a crucial role in reducing CO2 emissions. By integrating technology and sustainable practices into urban infrastructure, smart cities aim to minimize energy consumption and emissions. This research focuses on creating models that correlate CO2 emissions with the installed capacity of power plants and the energy they produce. Polynomial quadratic regression is applied to establish these correlations, enabling the assessment of both present and future CO2 emission values. The construction of new infrastructure for smart cities aligns with the broader goal of fostering a low-carbon economy. The study also considers the potential contribution of thermal energy to CO2 reduction efforts. Researchers aim to identify strategies for meeting emission reduction goals by analyzing power generation models. This involves implementing policies and technologies aimed at reducing GHG emissions and mitigating climate change. CO2 emissions contribute significantly to global warming, leading to climate change and patterns of extreme weather. The data on CO2 emissions encompasses gases generated from burning fossil fuels, highlighting the importance of reducing reliance on these energy sources.
Unbreakable SU(3) Atoms of Vacuum Energy: A Solution for Cosmological Constant Problem
Authors: Farag Ali Ahmed
Published: May 2024

This paper addresses the cosmological constant problem, a significant discrepancy highlighted by \cite{Weinberg:1988cp} that underlines a fundamental inconsistency between quantum field theory (QFT) and general relativity (GR). QFT examines matter dynamics within Lorentzian spacetime under standard model symmetry, while GR uses Riemannian geometry but adapts it to ensure local Lorentzian behavior in small regions. Despite the experimental successes of both theories, a major challenge exists in theoretical understanding. This letter seeks to clarify this critical misunderstanding. As the universe cools from its hot beginning, the \(SU(3) \times SU(2) \times U(1)\) standard model gauge symmetry evolves. This symmetry breaks to \(SU(3) \times U(1)\) upon cooling at the electroweak scale and ultimately to \(SU(3)\) alone as temperatures approach near-absolute zero kelvin, facilitated by the experimental Meissner effect. This suggests that \(SU(3)\) symmetry forms the foundational "atoms" of vacuum energy. Calculating the number of \(SU(3)\) vacuum atoms across the universe results in a value that perfectly aligns the theoretical predictions with the observed vacuum energy densities, thereby resolving the cosmological constant problem. Since \(SU(3)\) atoms account for the cosmological constant, they must be unbreakable. The third law of thermodynamics, which states that it is impossible to reach absolute zero Kelvin, provides the protection that prevents SU(3) atoms from breaking at zero Kelvin. This reveals the connection between the third law of thermodynamics and the quark confinement. This leads to the \(SU(3)\) atom creating a mass gap within the universe. This solution serves as a symmetric evidence of gauge-gravity duality as well as gravity-superconductor duality.
Cellulose Membranes: Synthesis and Applications for Water and Gas Separation and Purification
Authors: Wang Jinwu , Abbas Syed Comail , Li Ling , Walker Colleen C. , Ni Yonghao , Cai Zhiyong
Published: May 2024

Membranes are a selective barrier that allows certain species (molecules and ions) to pass through while blocking others. Some rely on size exclusion, where larger molecules get stuck while smaller ones permeate through. Others use differences in charge or polarity to attract and repel specific species. Membranes can be used to purify air and water by allowing only air and water molecules to pass through but preventing contaminants such as microorganisms and particles or to separate target gas or vapor, such as H2, CO₂, from other gases. The higher the flux and selectivity, the better a material is for membranes. The desirable performance can be tuned through material type (polymers, ceramics, and biobased materials), microstructure (porosity and tortuosity), and surface chemistry. Most membranes are made from plastic from petroleum-based resources, which contribute to global climate change and plastic pollution. Cellulose can be an alternative sustainable resource to make renewable membranes. Cellulose exists in plant cell walls as natural fibers, which can be broken down into smaller components such as cellulose fibrils, nanofibrils, nanocrystals, and cellulose macromolecules through mechanical and chemical processing. Membranes made from reassembling these particles and molecules have variable pore architecture, porosity, and separation properties and therefore have a wide range of applications in nano-, micro-, and ultrafiltration or forward osmosis. Despite their advantages, cellulose membranes face some challenges. Improving the selectivity of membranes for specific molecules often comes at the expense of permeability. The stability of cellulose membranes in harsh environments or under continuous operation needs further improvement. Research is ongoing to address these challenges and develop advanced cellulose membranes with enhanced performance. This article reviews the microstructure, fabrication methods, and potential applications of cellulose membranes, providing some critical insights into processing-structure-property relationships for current state-of-the-art cellulosic membranes that could be used to rationally improve their performance.
Colour Preferences for Surface Shapes on Residential Interior Walls
Authors: Ulusoy Begum
Published: May 2024

Researchers have explored primary colour-geometric shape associations since Kandinsky's correspondence theory. However, there is a gap in the literature regarding interior colour applications on surface shapes. To address this gap, an online study was employed to gather data with one hundred participants who were asked to choose their preferred colours for shapes on bedroom walls with follow-up questions on the colour-shape semantic associations, their preference of colours and shapes on bedroom walls independently in addition to their favourite colour, their favourite shape, and colour-shape pairs without interior context. The results revealed that colour-shape preferences in interiors differ from those found in psychology studies, other colour applications on bedroom walls, and other preferences, indicating that colour preference is context-dependent. Interestingly, the most popular colour for surface shapes on bedroom walls is purple, followed by brown and blue. The study contributes to the existing literature by providing colour charts for bedroom applications for professionals in the industry, their clients/users, and future studies.

Real-time material extrusion volume control system for 3D food printers
Authors: Ichimori Izumi , Watanabe Yosuke , Fujiwara Koki , Ogawa Jun , Furukawa Hidemitsu
Published: May 2024

To achieve high-quality printing with a 3D printer, it is important to set optimal printing parameters. In our research, we have advanced the development of a 3D food printer capable of rendering a variety of food products. Notably, the rheological properties of food-based inks are influenced by the constituent ingredients, ambient conditions such as temperature and humidity, and the specific recipe utilized, which significantly affects the precision of the printed models with the 3D food printers more than with conventional FDM (Fused Deposition Modeling) 3D printers. Given the necessity to modify printing parameters in real-time in response to fluctuations in temperature and material consistency, the process of food printing necessitates ongoing monitoring.An automatic control system is essential for accurate printing. We devised a monitoring system within the 3D food printer to calibrate extrusion volume accurately.Leveraging machine learning techniques with a dataset comprising food substances of diverse characteristics and colors, we have successfully automated the control of extrusion volumes within the 3D food printer. The time it takes to achieve good printing conditions is similar to users who are new to 3D food printing. Additionally, it automatically handles fluctuations in extrusion rate during printing, such as those caused by room temperature. This function will let 3D food printing user-friendly and lead more active development of 3D food printing products.
Intraoperative inhalation of indocyanine green for detection of air leak sites after lung resection: study protocol for a randomized controlled trial
Authors: Wang Zhenfan , Jiang Ruiheng , Cui zhuoer , Chen Hongchengcheng , Zhao Songjing , Li Yun , Zhou Jian
Published: May 2024

Background Postoperative air leak is a common complication after pulmonary surgery. Intraoperative identification and repairing of all air leaks are essential to prevent this complication. However, the traditional saline submersion test would cause oversight of some air leak sites because of the limited field of view in video-assisted thoracoscopic surgery (VATS), especially in patients with pleural adhesions. This trial aims to evaluate the efficacy of indocyanine green inhalation for intraoperative detection of air leaks during VATS.
Methods This multi-center, two-arm, prospective, randomized controlled, parallel group trial is designed to compare intraoperative indocyanine green (ICG) inhalation and saline submersion test in terms of identifying intraoperative air leak sites and reducing postoperative air leak. This trial will include 460 patients who will underwent VATS lung resection with a 1:1 randomization. The primary outcomes are the immediate postoperative air leak rate and the number and size of air leak sites during surgery. the secondary outcomes are time of detection, time of intraoperative repair, duration of chest tube, duration of postoperative air leak and the prolonged air leak rate.
Discussion The method for intraoperative detection of air leaks has remained unchanged for decades, which is constrained by the limited surgical field visibility in patients underwent VATS. Therefore, a novel technique without such limitation is meaningful for preventing oversight of the air leak sites. We hope the result of this study will provide valuable information on the clinical benefit of this novel approach for air leak detection.

Background: Balance and mobility deficits are major concerns in stroke rehabilitation. virtual reality (VR) training and Swiss-ball training are commonly used approaches to improve balance and mobility. However, no study has compared the efficacy of VR training and Swiss-ball training in improving balance and mobility function or investigated cortical activation and connectivity in individuals with stroke.
Methods: A prospective, single-blinded, parallel-armed, multi-center randomized controlled trial with 4 weeks of training will be conducted. Seventy-six participants aged 30–80 years with stroke will be recruited.Participants will be allocated to one of four groups: A) the VR + Swiss-ball training + conventional physical therapy group; B) the Swiss-ball training + conventional physical therapy group; C) the VR training + conventional physical therapy group; or D) the conventional physical therapy group. All participants will receive 50 min of training per day, 5 times per week, for a total of 4 weeks. The primary outcomes will be balance and mobility measures. Secondary outcomes will include the 10-minute walk test,dynamic gait index and cortical activation. Outcomes will be measured on three occasions: at baseline, after the training, and at the 4-week follow-up.
Discussion: This trial will provide evidence to determinewhether there are differences in clinical outcomes and cortical activation following two different types of exercise programs and/or their combination and to elucidate the recovery mechanisms of balance and mobility function in individuals with stroke.

Background: Vaccinology education forms a cornerstone of effective public health strategies, particularly in the face of global challenges such as vaccine hesitancy. This study investigates the current state of vaccinology education within Romanian medical universities, compares it against European standards, and identifies potential gaps in the curriculum.
Methods: We created a survey that aimed to determine the prevalence of vaccinology concepts within current curricula and to perform a gap analysis against the desired competency levels recommended by the European Society of Vaccinology.
The survey was distributed to faculty heads and independently to students across 14 medical universities in Romania. The survey focused on nine key areas of vaccinology.
Results: Seven universities participated, three of which met the inclusion criteria based on response rates. The study revealed that while certain areas of vaccinology, such as the historical context of immunization and key aspects of immunology, were well covered, practical aspects of vaccine administration were less emphasized. The survey also revealed a disparity between faculty and student perceptions of the importance of a specialized vaccinology curriculum.
Conclusions: The findings underscore a significant convergence between the current curriculum and desired educational standards yet highlight the need for curricular revisions to address less-covered areas. We advocate for the integration of specialized vaccinology courses at advanced stages of medical education. Aligning educational content with the needs perceived by students and faculty can help optimize the curriculum to better prepare medical professionals for public health challenges.

Bacillus velezensis, a member of phylum firmicutes, is a gram-positive rod-shaped and endospore-forming bacterium inhabiting diverse environments. The preliminary analysis of the whole genome of Bacillus velezensis ANY11, isolated from bamboo fiber humus in the intestines of Cyrtotrachelus buqueti, revealed that the genome is approximately 3,949,880 bp in length and contains 4265 coding genes. Among these, 12815, 2473, 3193, and 171 genes were annotated in the GO, KEGG, COG, and CAZy databases, respectively. Additionally, the virulence, pathogenicity, and antibiotic resistance of Bacillus velezensis ANY11 were analyzed using PHI, VFDB, and CARD databases. Based on the genomic sequencing and gene function analysis, Bacillus velezensisis believed to possesses certain disease resistance and the capability to hydrolyze lignocellulose, predicting its potential role in plant disease prevention and control as well as in the hydrolysis and reuse of lignocellulose lays The bioinformatics from this study may lay a foundation for the production of biofertilizers and biopesticides, as well as for the utilization of biomass in the production of clean energy ethanol.

Audiovisual conflict control is an important cognitive function in humans. However, it was not clear whether and how abnormal audiovisual conflict control was reflected at periods of perception and response in the cognitive process in Parkinson's disease (PD) patients. We recruited 27 PD patients and 22 healthy controls (HC) to complete audiovisual matching task to investigate the audiovisual conflict in PD patients at different processing periods and its relationship with cortical thickness. Behavioral results showed that abnormal audiovisual conflict at period of perception rather than response. The cortical thickness of left middle frontal gyrus (MFG) in PD patients was positively correlated with the sensory interference (visual interference > auditory interference) at period of perception. In addition, the results of support vector machines (SVM) showed revealed that models utilizing conflict at period of perception as a feature achieved higher predictive accuracy on the participant population, while those employing conflict at period of response as a feature did not. These finding suggested that perceptual conflict deficits in PD patients might be the causes of abnormal audiovisual conflict.
Investigating the Link Between Urban Expansion and Land Surface Temperature using GIS and Spectral Indices. The case of Peri urban South Chennai
Authors: R Narayani A , R Nagalakshmi
Published: May 2024

Built up expansion in peri-urban areas can have significant environmental consequences. Monitoring these land changes helps assess the impact on ecosystems. It allows for early detection of negative trends and helps develop strategies to mitigate environmental degradation. The present study investigates the correlation between expansion in peri urban areas and temperature on the surface of the land. The objective of the study is to evaluate the relationship and degree of the link between land surface temperature and urban growth using the spectral indices NDVI and NDBI. Satellite imagery for 1991 and 2001 was used to compute the NDVI, NDBI, and LST maps in ArcGIS. A grid set of 463 points was selected using the fish net sampling technique in the area of interest and correlated. A positive relationship between NDBI and LST, a negative relationship between NDVI and LST, and a negative correlation between NDVI and NDBI are all indicated in the results of the assessment. The results indicate that the increased area of greenspaces shows less land surface temperature. An increase in barren/built-up areas shows increased land surface temperature. These relationships highlight the interplay between urban expansion, vegetation cover, and temperature on the land surface. As lands in the peri-urban areas are consumed for urbanization, areas with high built-up density and limited vegetation will likely exhibit higher land surface temperatures causing urban heat islands. In comparison, regions with more vegetation tend to experience colder temperatures. A deep insight into these correlations can help urban planners and policymakers make informed choices that limit the negative consequences of urbanisation on the environment and human well-being and support sustainable urban growth.

Published: May 2024

Basalt is an extrusive igneous rock derived from lava and spread over different localities in Pahang. Kuantan basalts represent one of the largest bodies of basic extrusive in Peninsular Malaysia. Many studies of basalt rock focused on geochemistry and petrology and lacked comprehensive engineering investigations on Pantai Batu Hitam basalt rock. Thus, this study has investigated basalt rock's physical and chemical properties in Pantai Batu Hitam, Kuantan. The specimens were collected from different sites and prepared according to the International Society for Rock Mechanics Standard. Results exhibited that the basalt rocks in the studied location are classified as crystalline texture with a range of density (2.52–2.65), specific gravity (2.38–2.56), absorption values (0.92% − 0.97%), and rebound number of Schmidt hammer hardness test is average 44. The chemical composition of basalt rock specimens consists of SiO2 (42.20% − 44.56%), Al2O3 (12.36% − 16.54%), CaO (12.30% -13.10%), MgO (4.23% − 5.95%), K2O (4.14%- 4.95%) and Fe2O3 (3.23%- 3.95%) respectively. It indicates that the engineering properties of basalt in Pantai Batu Hitam, Kuantan is comparable with European countries. Therefore, this study supports using basalt rock from Kuantan for industrial applications such as basalt fiber, cast, and ceramic. The basalt fiber production can be expanded in Kuantan due to the availability of sources.

Published: May 2024

Background
Circular RNAs (circRNAs) are a class of noncoding RNAs that are involved in chondrogenic differentiation, and N6-methyladenosine (m6A) broadly exists in circRNAs.
Materials and methods
A joint injury model was constructed on Diannan small-ear (DSE) pigs. Transfections were constructed using Lipofectamine 2000. Real-time quantitative PCR (qPCR), Methylated RNA immunoprecipitation qPCR (MeRIP-qPCR), and western blotting analyses were performed. Alcian blue staining tested the chondrogenic differentiation ability. The potential m6A methylation modification enzymes and sites of circZCCHC14 were predicted in m6Avar and SRAMP databases. RNA pull-down and RIP assays were conducted to determine the interaction between circZCCHC14 and FTO.
Results
CircZCCHC14 expression and the m6A methylation level were increased in joint injury DSE pigs. m6A methylation and circZCCCHC14 expression levels were decreased during the process of cartilage differentiation. FTO was decreased, circZCCHC14 and m6A methylation level were increased under inflammatory conditions. FTO is one essential m6A demethylase enzyme of circZCCHC14. m6A demethylase enzyme FTO regulated the expression levels of circZCCHC14. m6A demethylase enzyme FTO positively regulated the expression of miR-181a. FTO m6A demethylase positively regulates chondrogenic differentiation through the circZCCHC14/miR-181a/GREM1 axis.
Conclusion
Our data showed the physiological significance of FTO m6A demethylase in regulating axis circZCCHC14/miR-181a/GREM1 and BMP2, providing a potentially effective therapeutic target for the treatment of joint injury or Osteoarthritis (OA).
