A Framework for Implementing a District-Wide School Wellness Needs Assessment: Using the WSCC Model
Authors: Weemer Megan , Eberline Andrew , Lee Joey , Kybartas Tyler , Jones Emily
Published: July 2023

Poor nutrition and insufficient amounts of physical activity are key contributing factors to childhood obesity and can adversely affect the physical, social, and emotional health, along with the academic success, of today’s youth. Comprehensive school-based initiatives, in combination with broader community efforts that target these behaviors, can help youth to develop and sustain healthy lifestyles through the adolescent years. The Whole School, Whole Community, Whole Child (WSCC) model emphasizes the connection between health and academic achievement and highlights the importance of school wellness assessments, stressing that schools serve as the nucleus in providing these supports with input, resources, and collaboration from the community. Inadequate amounts of attention have been given to the process of conducting school wellness assessments that promote collaboration between university research teams and key school district stakeholders. This article presents the process of conducting a district-wide wellness assessment with the WSCC model as the conceptual framework. It outlines practical steps for other districts to replicate and key collaboration principles, along with the specific use of a unique wellness assessment tool that includes a readiness for change component. It also discusses challenges and opportunities encountered, lessons learned along the way, and implications for school administrators and school health practitioners.
Diversity, Equity, and Inclusion in Kinesiology Departments
Authors: Pennington Colin G.
Published: July 2023

While kinesiology as a field and as an academic major has evolved and diversified considerably over the last several decades, the cultural and racial demographics of kinesiology majors has remained fairly similar to the demographic characteristics of the early 2000s and before. There is incongruence between the actual diversity of the American population and the diversity of the population in American higher education. This disparate status further extends to kinesiology programs and subsequent subdisciplines. While the responsible systemic racial and cultural variables are worthy to be considered, examined, and corrected, this article does not drill into such constructs. Instead, this article identifies the barriers and facilitators of cultural and racial demographics as expressed by kinesiology majors and kinesiology-related professionals in higher education kinesiology programs and the allied health professions. This article discusses the importance of actively promoting kinesiology to diverse populations in the community. It amplifies the message of many scholars calling attention to a lack of diversity, as well as promotes selected effective strategies being initialized in kinesiology departments and among the allied health professions.

Developing an Equity Mindset: How Neonatal Nurses Can Impact Health Outcomes by Reducing Disparities
Authors: Marcellus Lenora , Amundsen Miranda
Published: July 2023

The concepts of health equity and social justice are foundational to the profession of nursing. Substantial advances have been made over the past decades in the care of infants requiring support in the NICU; however, significant differences remain in health outcomes for infants and their families for groups considered to be disadvantaged. In this article, we explore the concept of health equity, introduce an action framework that provides a practical approach to advancing health equity, and describe how to apply this framework for action within the context of neonatal nursing practice. Nurses are encouraged to accept and act on their ethical responsibility toward the populations they serve, directing attention and resources to those with the greatest need.

Ijtihad of the Companions in Determining Grandfather's Inheritance Rights with Brothers and Sisters
Authors: Zuhdi M , Miharja Marjan , Rahmawati Dyah
Published: July 2023

The rule on the part inherited by the grandfather together with the siblings of the testator is not found at all from the nagli arguments in the Qur'an or as-Sunnah. The provisions of their share are found through the ijtihad of the Companions. The ijtihad of the Companions has differences with each other. Thus, it is important to conduct an in-depth study of the ijtihad of the Companions. The issue to be discussed in this research is how the grandfather's share of inheritance rights if he is with brothers and sisters based on the ijtihad of the Companions. The purpose of the research is to conduct a study of the grandfather's share of inheritance if he is with brothers and sisters according to the ijtihad of the Companions.  This research uses a type of qualitative research whose data comes from secondary data. Documentation study was chosen in collecting data, while data analysis was carried out in three stages, namely data reduction, data verification and data presentation. The results of this study reveal that there are still things that require ijtihad in resolving the issue of grandfather's share of inheritance with the inheritor's siblings that occur in the community. The findings are based on the example of calculating inheritance according to the opinions of Abu Bakr, Zaid bin Tsabit, Umar and Ibn Mas'ud.

Authors: Gunawan Yusuf
Published: July 2023

The purpose of this research is to overcome dual identities or brands that have similarities in principle or in whole for similar and/or dissimilar goods or services that go side by side where the ownership rights are obtained through trademark registration or through a decision from the Supreme Court which is protected by law. as the identity of the goods and/or services being traded. The research method used is normative juridical. The formulation of the problems in this study are: 1. How is the regulation of trademarks that are rejected for registration that have similarities in principle or as a whole; 2. How to set a registered mark with a second identity. The findings of this research are based on Law Number 20 of 2016 concerning Trademarks and Geographical Indications (MIG) where trademarks are denied registration on the grounds of equality in principle and/or in whole for similar goods or not similar to other marks registered in bad faith belonging to other parties and the need for a second identity of a registered mark and/or a well-known mark in dealing with marks that are similar in principle and/or in whole that run side by side and required legal protection for registered marks to obtain legal certainty and there needs to be a scientific study of the proposed identities of the two brands.

Authors: KURTULDU Mehmet Kayhan , KUBALİÇ Cemre Deniz
Published: July 2023

This study aimed at examining to what extent the walking game activity is effective in teaching of asymmetrical (aksak) rhythm patterns in piano education. The study used the experimental method by setting up control and experiment groups each of which was composed of 11 people. In this practice that was conducted with students receiving the piano class in a private course whose ages ranged between 8 and 9, walking game activity was used to teach asymmetrical rhythm patterns. The practice was based on cards on which the rhythm patterns were written and repetition of the rhythm patterns formulated according to these cards with a walking game, and the final performances were measured with a given piano piece. A pre-test was also given to the students to measure the levels of students before the practice. Digital data obtained through the practice were statistically analysed. In pre-test and post-test measurements, the Man Whitney U test was used. It was concluded as a result of the measurements that, in the post-test process, the students in the experiment group who studied with the walking game activity performed better in understanding and vocalizing the asymmetrical rhythm patterns compared to the students in control group.

Published: July 2023

Un programme de recherches sur l'utilisation des pâturages tropicaux par le bétail domestique a été mis en place au Sénégal. Au cours des études sur le terrain, de nombreuses informations ont été recueillies et de nombreux prélèvements effectués. Ces derniers visaient essentiellement trois buts : connaissance de la composition du pâturage, de la composition du régime alimentaire et relations entre eux. La méthode dite des épidermes, plus fréquemment utilisée en zone tempérée, a été retenue pour analyser et comparer la composition botanique de 105 échantillons : collectes du berger, prélèvements oesophagiens et fèces, recueillis au cours d'un cycle de 12 mois. Au vu des résultats obtenus, quelques problèmes méthodologiques sont soulevés et discutés.
Conduite de la reproduction en grands troupeaux laitiers dans les conditions marocaines. III. Reprise des chaleurs et anoestrus post-insémination naturelle
Authors: Lakhdissi H. , Haddada B. , Lahlou Kassi A. , Thibier M.
Published: July 2023

Cette étude vise à caractériser l'exactitude et le taux de détection des chaleurs, ainsi que l'incidence de l'anoestrus post-insémination dans 4 grands troupeaux laitiers marocains (369 femelles). La détection des chaleurs a été effectuée quotidiennement et des prises de sang destinées à la mesure de la concentration de progestérone plasmatique (P) ont été réalisées le jour de l'insémination naturelle, 12 jours plus tard, puis 21 jours après celle-ci. L'exactitude (E) est définie comme le rapport du nombre d'oestrus corrects sur le nombre des oestrus détectés lors de l'insémination. Le taux de détection (T) est défini par le rapport du nombre d'oestrus détectés sur le nombre d'oestrus attendus 21 jours après celle-ci. L'incidence de l'anoestrus post-insémination est le complément de ce taux T. Dans les conditions de ces troupeaux laitiers marocains, E = 91 p. 100 et T = 49 p. 100. L'incidence de l'anoestrus post-insémination est donc supérieure à 50 p. 100. La répartition des retours en chaleurs des vaches saillies inopportunément (9 p. 100) permet de reconnaître les femelles inséminées en pleine phase lutéale, et celles qui ont un décalage de 1-2 jours entre phase folliculaire et oestrus. Enfin, l'incidence élevée d'anoestrus post-insémination démontre l'inadéquation du comportement d'oestrus comme seul élément de diagnostic de présomption de gestation.

Published: July 2023

O presente estudo, filiado aos domínios teóricos da Análise de Discurso, busca trabalhar com a noção corpo-e-sujeito como um lugar para se pensar a relação significante entre ambos. Para tanto, fundamentam esta pesquisa os estudos de Pêcheux (1975; 1995) e Orlandi (2012; 2014), ao compreenderem corpo e sujeito enquanto materialidades discursivas. O recorte de análise é constituído por imagens da cantora e atriz Liniker, trechos da entrevista concedida à TV Trip, e, ainda, seu discurso proferido diante da premiação no Grammy Latino. Tais materialidades discursivas permitiram apontar para a possibilidade de outras formas de significação para corpo e para sujeito capazes de produzir um efeito de suspensão da norma, constituindo, assim, outras filiações de sentido na memória do dizer.

Published: July 2023

La esclerosis múltiple es una enfermedad crónica, inflamatoria, desmielinizante, de etiología autoinmune que afecta al sistema nervioso central. Es la causa más común de discapacidad neurológica no traumática en adultos jóvenes. El 10 % de pacientes con esta enfermedad son diagnosticados con la forma esclerosis múltiple primaria progresiva (EMPP) que, hasta la aparición del anticuerpo monoclonal anti-CD20 ocrelizumab, no tenía una terapia específica. Se presenta el primer caso de EMPP tratado con ocrelizumab en el sistema público peruano. El paciente presentó una tolerabilidad aceptable y una respuesta clínica adecuada, medida con la Escala Expandida del Estado de Discapacidad (EDSS). Se destaca que, en la legislación peruana, la esclerosis múltiple es considerada una enfermedad rara que requiere una evaluación ad hoc para la autorización de financiamiento público para terapias específicas.
Nonprofit Management Researchers’ Reconceptualization of Comprehensive INGO Accountability: Toward an Institutional Logics Approach
Authors: Hengevoss Alice
Published: July 2023

International nongovernmental organizations (INGOs) face greater accountability demands from various stakeholders, and from their beneficiaries in particular. This has initiated an academic discourse on a more comprehensive approach to INGO accountability to maintain their legitimacy. This article addresses two research questions: What is the current understanding of accountability of INGOs? And what are theoretical venues to strengthen future research on comprehensive INGO accountability? It does so by offering a systematic literature review of the current academic discourse on INGO accountability, and advances four propositions on what comprehensive INGO accountability entails. The review further highlights that INGO accountability is dynamic and complex. The article therefore suggests a theoretical foundation that accounts for these aspects to support researchers interested in further developing comprehensive INGO accountability. It demonstrates how an institutional logics approach allows conceptualizing INGO accountability relationships to a wider set of stakeholders, including to beneficiaries. It further allows advancing an effectiveness-oriented conceptualization.

Melting Heat Transfer Rheology in Bio-Convection Cross Nanofluid Flow Confined by a Symmetrical Cylindrical Channel with Thermal Conductivity and Swim Microbes
Authors: Awwad Fuad A. , Ismail Emad A. A. , Gul Taza , Khan Waris , Ali Ishtiaq
Published: July 2023

Nonlinear thermal transport of non-Newtonian polymer flows is an increasingly important area in materials engineering. Motivated by new developments in this area which entail more re-fined and mathematical frameworks, the present analysis investigates the boundary layer ap-proximation and heat transfer persuaded by a symmetrical cylindrical surface positioned hori-zontally. To simulate thermal relaxation impacts the bioconvection cross nanofluid flow Buongiorno model is deployed. The impact of the magnetic field applied on the nanofluid using the heat generation and melting phenomena are inspected. The nonlinear effect of thermosolutal buoyant forces is incorporated into the proposed model. The novel mathematical equations comprise thermophoresis and Brownian diffusion effects. Via robust transformation techniques, the primitive resulting partial equations for momentum, energy, concentration, and motile living microorganism are rendered into nonlinear ordinary equations with convective boundary postulates. An explicit and efficient numerical solver procedure in Mathematica 11.0 programming platform is developed to engage the nonlinear equations. The consequence of multiple governing parameters on dimensionless fluid profiles is inspected through plotted visuals and tables. Finally, outcomes declared on the surface drag force, heat, and mass transfer coefficients are exhibited through 3D visuals via different influential parameters.
Congenital Partial Colonic Agenesis in Dogs and Cats: Clinical, Biological, Diagnostic Imaging, Endoscopic and Histopathologic Characterization. A Retrospective Study of 23 Cases
Authors: Remmel Paul , Gros Lucile , Mortier Jérémy , Freiche Valérie G
Published: July 2023

Congenital diseases of the large intestine have scarcely been reported and mostly include fistula, atresia, or colonic duplication. Cases of partial colonic agenesis have rarely been described. The purpose of this study was to report a cohort of dogs and cats diagnosed with partial colonic agenesis. The colon was measured during colonoscopy or contrast-radiography and compared to the average length described in the literature. Six dogs and 17 cats were retrospectively included. Depending on the case, partial colonic agenesis could represent an incidental finding or the likeliest cause of clinical signs. Diarrhea was reported in most cases, and no specific clinical or biological abnormality was observed. Median age of presentation was variable and long asymptomatic periods were common. Abdominal ultrasound was useful and identified a short colon in 14/17 cats but only in one dog. Endoscopy was useful to confirm the diagnosis and to identify associated lesions and complications. Among others, colonic stenosis was reported in 8/9 cases that had lifelong clinical signs and the shortest colon length. This anatomical abnormality could promote chronic inflammation that might generate fibrosis and ultimately stenosis.
A Fast Gradient Iterative Affine Motion Estimation Algorithm Based on Edge Detection for Versatile Video Coding
Authors: Hong Jingping , Dong Zhihong , Zhang Xue , Song Nannan , Cao Peng
Published: July 2023

In the Versatile Video Coding (VVC) standard, affine motion models have been applied to enhance the resolution of complex motion patterns. However, due to the high computational complexity involved in affine motion estimation, real-time video processing applications face significant challenges. This paper focuses on optimizing affine motion estimation algorithms in the VVC environment and proposes a fast gradient iterative algorithm based on edge detection for efficient computation. Firstly, we establish judging conditions during the construction of affine motion candidate lists to streamline the redundant judging process. Secondly, we employ the Canny edge detection method for gradient assessment in the affine motion estimation process, thereby enhancing the iteration speed of affine motion vectors. Experimental results demonstrate that our affine motion estimation algorithm reduces encoding time by approximately 15%-35% while maintaining video bitrate and quality.
Role of Magnetic Resonance Imaging in Pelvic Organ Prolapse Evaluation
Authors: Sarpietro Giuseppe , Foti Pietro Valerio , Conte Carmine , Matarazzo Maria Grazia
Published: July 2023

Background and objectivesː Physical examination is the predominant method for evaluating pelvic floor defects. Magnetic Resonance Imaging (MRI) is a radiological technique useful to identify the underlying defects of pelvic floor structures that require surgery. The primary aim was to find correspondence between the clinical and radiological staging of pelvic organ prolapse (POP) before and after vaginal surgery. A secondary endpoint was to investigate, through clinical and MRI findings if surgery influences continence mechanisms. Finally, we reported changes in the quality of life in women who underwent surgery for prolapse.
Materials and methodsː Twenty-five women with prolapse stage ≥ 2 POP-Q were recruited in this prospective study. They underwent preoperative clinical examination, MRI at rest and under the Valsalva maneuver, and quality of life questionnaires. Three months after vaginal surgery they repeated clinical and radiological evaluation.
Resultsː Twenty women completed the study. Both clinical and MRI evaluations showed an improvement in prolapse and symptoms after surgery. There were some discrepancies between clinical and radiological staging. MRI parameters did not show differences between pre and postoperative at rest; under the Valsalva maneuver instead, the measurements changed after surgery. Continence was not worsening by the widening of the vesicourethral angle. Patients reported improvement in quality of life.
Conclusionsː MRI is an accurate and objective method to define the stage of prolapse but the clinical evaluation alone is sufficient to stage prolapse before surgery and evaluate the result at follow-up. It is an accurate method to visualize some pelvic structures that can be compromised because of pelvic organ prolapse. MRI showed that vaginal surgery doesn’t affect continence mechanisms.

Authors: Eslit Edgar Rendon
Published: July 2023

This paper explores the dynamic interplay of K-12 education, the Fourth Industrial Revolution (IR 4.0), and internationalization in the Philippines. Through qualitative content analysis, key themes emerged, shedding light on the impact of K-12 education on global competitiveness, challenges in embracing IR 4.0 technologies, and opportunities arising from internationalization efforts. The findings underscore the significance of curriculum alignment with international standards, comprehensive digital literacy training, and fostering a global mindset to prepare students for the digitally-driven, interconnected world. Understanding the implications of these themes is crucial for the Philippines' education system, as it navigates towards a transformative and globally competitive future. Further, this research offers evidence-based recommendations and addresses research gaps, contributing to a broader understanding of how the convergence of these forces shapes the future of Philippine education. Future research avenues may explore long-term impacts on workforce preparedness, innovative IR 4.0 integration, and the effectiveness of internationalization efforts on educational outcomes. Eventually, this study inspires an education system that nurtures learners equipped to thrive in an ever-evolving global landscape.
The Acute Effects of Schoolbag Loading on Posture and Gait Mechanics in 10-to13-year-old Children: A Cohort from the North-West Province
Authors: Grobler Bridget , Kramer Mark
Published: July 2023

Most schoolchildren carry schoolbags, of which a substantial proportion carry loads that exceed 15% of their body mass. Although the effects of loading have been investigated to varying degrees, the status of schoolbag loading and the acute affects thereof on gait and posture have not been thoroughly investigated within the South African context. A total of 60 participants in the 10-13-year age range volunteered for the present study. Significant differences were evident for relative load carriage (χ2(3) = 14.54, p < .001), forefoot and heel forces (Mdiff = 17.05-34.86 N, p < .001), force-ratios (Mdiff = 0.02, p = .029), and gait speed (Mdiff = -0.18 km/hr, p = .016).), but not for any postural angles (Mdiff = -3.37-6.08 deg, all p > .052). Those who exceeded 15% BM were ~9 times more likely to report pain than those below 15% BM. The children in the current carried significantly heavier realtive loads (p < .001) compared to similarly aged children from other countries. Loading leads to acute changes in posture and gait that are likely not meaningful. However, excessive loading (>15% BM) leads to significantly higher perceptions and reporting of pain in 10-13 year-old children.
A New Perspective on Hydrogen Chloride Scavenging at High Temperatures for Reducing Smoke Acidity of PVC Cables in Fires. V: Comparison Between EN 60754-1 and EN 60754-2
Authors: Bassi Iacopo , Bandinelli Claudia , Delchiaro Francesca , Piana Marco , Sarti Gianluca
Published: July 2023

Regulation (EU) No 305/2011 lays down harmonized conditions for marketing construction products in the European Union. One of its consequences has been the introduction of the product standard EN 50575 and standard EN 130501-6, concerning power, control, and communication cables permanently installed in buildings to prevent the risk of a fire and its consequences. EN 13501-6 provides the reaction to fire classifications for cables, the test methods to be performed, the requirements to meet a specific reaction to fire, and additional classifications for smoke production, flaming droplets, and acidity. EN 60754-2 is the technical standard used to assess acidity, and it defines three classes: a1, a2, and a3 (the less performant), based on pH and conductivity measurements. Due to the release of hydrogen chloride during the combustion, acidity is the weak point of PVC cables, which are not yet capable of achieving the a1 or a2 classes required in specific locations according to a fire risk assessment. EN 13501-6 does not include EN 60754-1. Both EN 60754-1 and EN 60754-2 are common standards for determining halogen gas content, acidity, and conductivity, respectively. They involve the same type of tube furnace but with different heating regimes, final temperatures, and detection methods. EN 60754-2 must be performed at temperatures between 935 – 965 °C. The paper demonstrates that, when EN 60754-2 is carried out with the thermal profile of EN 60754-1 or at 500 °C in isothermal conditions, the evolution of hydrogen chloride changes significantly if potent acid scavengers are utilized in the PVC compounds. The reason lies behind the kinetic of hydrogen chloride release during the combustion of PVC compounds: the higher the temperature or faster the heat release, the quicker hydrogen chloride evolution and the lower the probability for the acid scavenger to trap it. That further highlights the "fragility" of EN 60754-2 as a tool for assessing the risks associated with the release of hydrogen chloride in case of fire

Published: July 2023

A close-range photogrammetric approach and its implementation using a CNC device and a macro camera are proposed. A tailored image acquisition approach is proposed that is implemented using this device. To increase reconstruction robustness and accuracy, the key point features detected in the acquired images are tracked across multiple views from multiple viewpoints at multiple distances. This approach reduces spurious correspondences and, as a result, the estimation accuracy of calibration parameters is increased and reconstruction errors are reduced. Qualitative and quantitative evaluation demonstrate the efficacy and accuracy of the proposed approach, which exhibits micrometre resolution and low implementation cost.
The Swedish Bollnäs Skull – a Possible Native American Skull from San Nicolas Island in California
Authors: Wärmländer Sebastian K.T.S.
Published: July 2023

In the 21st century, museums have come to realize that the human skeletons they display might have problematic origins. The older anthropological skeletal collections typically originate from anatomical dissection of the executed and the very poor, or from scavenged graves of indigenous people. Such collections are currently being re-evaluated in many countries, and reburying or repatriating museum skeletons have become viable options. A particularly difficult question is what to do with human remains of unknown origins. Here, we present and discuss one such case, where a human skeleton of unclear origin in the 1930’s was brought to a local museum in Bollnäs, Sweden, under likely unethical circumstances. Most of the bones have now been lost, except for the skull, the sacrum and one lumbar vertebra, which in 2007 were transferred to the Museum of Ethnography in Stockholm. The skull was there put on display as the “Bollnäs skull”, and was presented to the public to illustrate the dilemmas involved in handling human remains in the post-colonial era. The original gift letter from 1934 stated that the skeleton came from San Nicolas Island outside the California coast, but this letter contained numerous instances of incorrect information and was therefore deemed not trustworthy. However, our critical examination of the skull and its background information indicates that San Nicolas Island is a plausible origin, and we suggest that a bioarchaeological comparison should be made between the skull and living descendants of the San Nicolas Island population, and/or with archaeological human skeletons excavated from the island.

Shallow-depth cementing presents unique challenges due to its low temperature and low pore pressure characteristic. The curing process of the cementitious material is typically prolonged at low temperatures resulting in a delayed curing process. The use of a low-density slurry to mitigate low pore pressure introduces another challenge, as it leads to a reduction in the final compressive strength. On the other hand, the operation requires the material to develop enough strength swiftly to be able to efficiently continue the next drilling operation. In addition, the presence of flow zones such as shallow gas and shallow water flow increases the complexity of the cementing process. There have been many developments in cementitious materials for shallow-depth cementing such as rapid-hardening cement and gas tight cement. However, there is little research focusing on the performance evaluation of each material at low-temperature conditions. This paper aims to present a thorough material evaluation for low-temperature shallow-depth cementing. The incorporated materials are American Petroleum Institute (API) Class G cement, rapid-hardening cement, gas tight cement, and geopolymer. Geopolymer is included to evaluate its potential as the green alternative to Portland-based cement. The sets of characterization were conducted during the liquid, gel, and solid phases. The samples were prepared under wide-ranging low temperatures and typical bottomhole pressures for shallow sections. The result shows different performances of each material and its behavior under low temperatures such as prolonged strength development and low reactivity, which necessitates further development of these materials.

Objective: Spinal surgeons have developed novel minimally invasive (MIS) protocols to correct adult degenerative spinal deformities in well-selected patients. Many surgeons perform these cases in stages: first by an anterior/lateral approach for interbody device placement, and second by a posterior approach for fixation. Imaging is typically obtained in between these 2 stages to reassess the surgical anatomy. We evaluated the utility of interstage imaging by comparing alignment parameters between baseline, interstage, and final postoperative radiographs. Methods: We reviewed MIS deformity cases performed at our institution by 3 expert surgeons, which were staged and had complete preoperative, interstage, and postoperative radiographs. Standard alignment parameters at all timepoints were compared.Results: Thirty-three patients met the criteria for inclusion. There were significant differences between baseline and interstage values for lumbar lordosis (LL, p = 0.004), pelvic tilt (PT, p = 0.002), and pelvic incidence-lumbar lordosis mismatch (PI-LL, p = 0.002). No significant differences existed between interstage and postoperative measurements for these sagittal parameters. Significant differences were found between interstage and postoperative values for the major Cobb angle (p = 0.012) and the lumbar Cobb angle (p = 0.016). Conclusions: In staged cases, our surgeons typically obtain interstage imaging, primarily standing scoliosis films. These studies inform the final levels of instrumentation and the need for additional posterior osteotomies/decompression during stage II. Based on interstage imaging findings, most sagittal correction occurs after stage I, while coronal correction occurs after stage II.

Vehicular Ad-hoc Networks (VANET) as the key correspondence organizing innovation has been pulled in by the scholarly world and enterprises with surprising turn of events. With each vehicle acting as a node in an ad hoc network made up of immobile or mobile vehicles, the VANET, which connects vehicles over a wireless connection, is a developing research field that is garnering prominence. The authors of this study examined real-time vehicles and the outcomes of four routing protocols on the basis of three parameters are recorded using Network Simulator (NS-3) as network simulator and synchronized with Simulation on Urban Mobility (SUMO) as mobility simulator. A dataset is compiled using recorded results with NS-3 and SUMO. For selecting the efficient routing protocol, collection of dataset and selection of different features is done. Machine Learning (ML) models such as Random Forest (RF), Logistic Regression (LR), and k-Nearest Neighbor (k-NN) are implemented utilizing a set of relevant information regarding the relationship between sender and receiver. The effectiveness of ML models is assessed using a novel dataset and especially in comparison to that with others. The results shows that k-NN outperforms on the basis of evaluation parameters: F-score (75.5%), Accuracy (97.2%), Recall (79.9%) and Precision (75.3%) of classification learning techniques. The purpose of this research is prediction and analysis of ML Models for efficient routing protocol in VANET using different feature information that may be utilized to improve effectiveness of VANET and provided efficient routing protocol for safe, secure, reliable connection between vehicles.

Terahertz (THz) communication is developing into an important technology for next 6G networks owing towards the ultra-wide bandwidth it provides. Precoding is a crucial approach in THz communication to get around the THz signals’ severe path loss and support the needed coverage. The primary problems of the prevalent THz precoding approaches for upcoming 6G networks are carefully investigated in this research. To be more precise, we first show how the main distinctions between millimeter-wave and THz channels are made clear. From there, we highlight the main difficulties with THz precoding, including the beam split effect and high power consumption.In THz massive MIMO systems, where the directional beams will split into several substantial directions at different sub-carrier frequencies, recent hybrid precoding approaches relying on frequency-independent phase-shifters are unable to handle the beam split effect. In THz mMIMO systems, the beam split effect will cause a significant array gain loss across the whole bandwidth, which has not been thoroughly studied.As a result, delay-phase precoding and hybrid precoding are suggested in this work. Then, after carefully examining its range of time delayers and antenna elements and making a association with frequency (milli meter wave and SubTHz have been examined), we move on to its design. The suggested delay-phase precoding approaches outperform the other wideband and narrowband precoding techniques already in use. To compare these typical THz precoding techniques and draw some conclusions for their usage in upcoming 6G networks, present simulation results of spectral efficiency.

Background
Keloids are an excessive growth of skin fibres that occur during the pathological wound healing process following skin injury. Although the use of adipose-derived mesenchymal stem cells (ADSCs) to treat keloids and their anti-fibrotic effects have been a subject of intense research, the precise mechanism and efficacy of this therapy remain unclear. This study aimed to identify an effective ADSC therapy for keloids.
Methods
We compared the transcriptome characteristics of keloid fibroblasts (KF) and normal fibroblasts, as well as keloid keratinocytes (KK) and normal keratinocytes. Using differentially expressed gene analysis, gene set enrichment analysis, protein-protein interaction network analysis, hub gene analysis, and transcription factor regulation analysis; we identified the molecular characteristics underlying keloid pathogenesis. Furthermore, we used single-cell RNA sequencing and bioinformatics analysis to identify functional ADSC subclusters with inhibitory effects on keloid development. Finally, we investigated the effectiveness of the identified ADSC subclusters in preventing hypertrophic scar formation using a miniature pig model.
Results
We found that genes such as NOG and IL6 were up-regulated in KF, and interacted with other molecules to promote immune regulation, angiogenesis, and tissue regeneration, leading to the formation of KF. In KK, genes such as APP, NOTCH1 regulated migration, invasion, proliferation and fate determination of cells, leading to the formation of KK. We successfully identified hADSC subclusters that inhibited the development of KF, KK, or both, and miniature pigs treated by pADSCs with higher ratio of these therapeutic clusters shown better hypertrophic scar prophylaxis.
Conclusion
Our study provides a comprehensive understanding of the molecular characteristics of the keloid in humans, and is the first to identify therapeutic ADSC clusters for keloids, offering new avenues for stem cell-based keloid treatments.
