Case Study of Attendance System Design Based on Web and Mobile
Authors: Zerach Jonathan Raden Abel
Published: November 2024

The current problem is that the attendance process at SMA Negeri 1 Rantau Pulung is still done manually. This becomes a problem when the attendance book is lost or exposed to water, which causes the writing on the attendance book to become blurry. The impact that could occur if the attendance application is not made is that SMA Negeri 1 Rantau Pulung will continue to carry out the attendance process manually and could be affected by the problems mentioned previously. Another impact is being left behind in the field of technology in the current era of digitalization. The step in solving the problem was that the researcher contacted the principal of SMA Negeri 1 Rantau Pulung to offer a presence application, then the researcher asked for the data needed to build the presence application. The temporary results currently obtained are that the presence application has been successfully developed and can now carry out the attendance qrcode scanning process. The conclusion from the interim results of this research is that web and mobile based attendance applications have been successfully developed. The presence application can generate QR codes on the web and can scan the generated QR codes via a mobile application.
The Substitute Notary's Responsibility for the Deed He Made
Authors: PUTRA Gede Bagus Andika , DHARSANA I Made Pria , WESNA Putu Ayu Sriasih
Published: November 2024

Purpose: A Substitute Notary is temporarily appointed as a Notary to replace a Notary who is on leave or sick. In Article 65 of the UUJNP, there is no explanation regarding the limits of the Substitute Notary's liability after his/her term ends. It is illogical because the limits of the Substitute Notary's authority end when the limits stated in his/her decision letter have expired, and he/she must still be responsible until his/her last breath.Methodology:The author uses a normative legal research method, legislative approach, legal concept analysis, case approach and comparative approach. The author's legal sources use primary and secondary law and tertiary legal materials. The legal collection technique uses document study techniques and recording.Findings: The responsibilities of a substitute notary can be divided into 4, namely: (1) Civil Liability of a Substitute Notary, (2) Criminal Liability of a Substitute Notary, and (3) Administrative Liability of a Substitute Notary. Legal protection for a substitute notary can be divided into 2: preventive legal protection and repressive protection.Implication:The responsibility of the Substitute Notary is only in the formal form of the authentic deed as stipulated in the law, so the Notary is not responsible for the contents of the deed. When carrying out their duties, a substitute notary will receive legal protection, including preventive legal protection to prevent disputes from occurring and repressive protection to resolve disputes that have already occurred. It is outlined in Article 66 of the UUJNP as a form of settlement effort if the notary is questioned.

Horizontal walls effect on the subsonic flow around airfoil by the image method
Authors: Belgroune Mounira , Yahiaoui Toufik
Published: November 2024

The aim of this work consists in developing a new numerical method and a calculation program making it possible to determine the effect of one and two horizontal walls on the distribution of the pressure ratio, and the aerodynamics coefficients of a subsonic flow around airfoils. The model is considered for the perfect gas. The calculation is presented by adding the effect of one and two walls on the discretization of the airfoils boundary to obtain a closed surface. The method is called by the image method.  So for the case of the existence of one wall, we will see a single image of the main airfoil, and in the case of two walls, we will have an infinity of images. The equation system is obtained by considering the effect of all images using alternating digital series, whose convergence is ensured numerically. We therefore obtain a large system of equations, the resolution of which is done by the Khaletski method to obtain the velocities and pressure. The application is made for some practical interest’s airfoils. Since the airfoils boundary is given by tabulated values, the cubic spline interpolation is used to obtain an analytical equation of the upper and the lower surfaces. The comparison is made with the case of open air flow by extending the distance between the walls and the airfoil chord towards infinity.
Teaching and Learning Resilience and Adjuvant Lessons from the COVID-19 Crisis: A Reflective Practitioner’s Perspective
Authors: Motsaathebe Gilbert
Published: November 2024

The coronavirus (COVID-19) was devastating to society. In addition to the untold anguish it unleashed on humanity, the pandemic considerably affected teaching and learning. The disruption to the school calendars resulted in a new shift that was constraining for both students and educators during the early stages of the pandemic. It is, therefore, unsurprising that many studies examining this pandemic’s impact tend to focus on its negative consequences. Thus, a less explored topic is the positive spin-offs of the crisis and how humanity transcended the abyss (in the Hegelian sense) amid agony. Therefore, this article fills this gap by examining some of the positive contributions and future possibilities resulting from society’s efforts to mitigate the effects of the pandemic. In terms of the method, the study draws on the author’s teaching experience and student feedback using an interpretative framework based on Driscoll’s What Model of reflection and insights from Resilience Theory and Reflective Practice. The findings highlighted humanity’s ability to bounce back in any crisis despite its magnitude and some of the innovative teaching and learning strategies that resulted in students being integral co-creators in the teaching and learning process. Based on the findings, the study ultimately proposes a five-stage crisis resilience model along a continuum of various cycles. The study contributes to embryonic scholarship that uses the pandemic as a lens to explore value creation and liberating avenues for humanity.

Published: November 2024

Penelitian dengan metode kualitatif deskriptif dengan pendekatan literatur ini dilakukan untuk menemukan apa peran Roh Kudus dalam penginjilan kontekstual.  Dalam melaksanakan Amanat Agung, gereja telah melakukan berbagai upaya penginjilan.  Banyak metode yang telah dipakai, demikian juga berbagai pendekatan yang dirasa relevan bagi Masyarakat.  Salah satu pendekatan yang digunakan untuk menjangkau orang atau komunitas yang belum mendengar Injil adalah pendekatan kontekstual.  Penginjilan dengan pendekatan kontekstual penting untuk dilakukan mengingat tidak ada metode dan strategi yang dapat digunakan di semua tempat, di semua masa dan setiap keadaan.  Perlu ada pendekatan lain yang sesuai dengan konteks budaya, adat kebiasaan, bahasa setempat sehingga lebih menyatu dan menyentuh kehidupan masyarakat dan Injil bisa diterima.  Namun demikian, kontekstualisasi hanyalah pendekatan manusiawi yang tidak menjamin hasil.  Roh Kuduslah pemegang peranan terpenting dalam penginjilan kontekstual.  Para penginjil kontekstual bisa memberitakan Injil, bertahan dalam situasi sulit dan menikmati hasil tuaian karena peran dari Roh Kudus.

Peran Majelis Dalam Pelaksanaan Disiplin Gereja Berdasarkan Matius 18:15 Bagi Anggota Jemaat Yang Melakukan Pelanggaran Dosa
Authors: Supriyanto Eko , Sugiharto Ayub
Published: November 2024

Tujuan penelitian ini adalah untuk mengetahui peran majelis gereja dalam pelaksanaan disiplin gereja berdasarkan Matius 18:15.  Gereja ada karena kehendak Tuhan dan menjadi komunitas orang percaya untuk mengalami pertumbuhan rohani. Walaupun sudah menjadi anak-anak Allah, faktanya kuasa dosa tidak secara otomastis hilang dalam diri anak-anak Allah. Melakukan dosa berarti melenceng dari aturan Tuhan dan akibatnya adalah keterpisahan dengan Allah, walaupun seperti dekat dengan-Nya. Oleh karena itu majelis sebagai pemimpin gereja memiliki tanggungjawab tidak hanya mengawasi pertumbuhan rohani jemaat, tetapi juga menolong supaya jemaat meninggalkan dosa. Disiplin gereja merupakan sarana untuk menolong umat yang kedapatan melakukan dosa dengan tujuan supaya kembali di jalan Allah, namun jika disiplin salah dalam penerapan,  justru menimbulkan masalah baru. Dengan meneliti Matius 18:15 sesuai dengan prinsip hermeneutik, penelitian ini bertujuan menjelaskan prinsip-prinsip dalam pelaksanaan disipilin gereja bagi jemaat yang kedapatan melakukan dosa sesuai Matius 18:15. Hasil penelitian, disiplin adalah bentuk kasih kepada saudara seiman yang bertujuan menolong mereka untuk meninggalkan tabiat dosa dan mengalami pertumbuhan rohani. Sedangkan majelis sebagai eksekutor harus memiliki kedewasaan rohani.
Learning Gravity Fields of Small Bodies: Self-adaptive Physics-informed Neural Networks
Authors: Ai Gangzheng , Yin Jihao , Cui Linyan
Published: November 2024

The reconstruction of the gravity field within the surface region of small bodies is crucial for the surface proximity operations of a probe. However, the irregular shape, uneven mass distribution, and sparse gravitational data of small bodies pose challenges in the reconstruction. We propose a self-adaptive physics-informed neural network (PINN) for the reconstruction of the gravity field within the surface region of irregular and heterogeneous small bodies. First, we introduce an auxiliary-point-based data augmentation strategy to reduce the model’s dependency on the quantity of data. Second, we incorporate a residual-based adaptive sampling strategy to enhance the prediction accuracy of the model in regions with significant variations in small-body density. Finally, we introduce an adaptive weight module based on gradient ascent to mitigate the balancing issue of loss terms in the PINN. Experiments indicate that our algorithm achieves improved accuracy for reconstructing the gravity field within the surface region of small bodies. This work is expected to contribute to the enhancement of safety in surface proximity operations around the surfaces of small bodies.
3D Hydrodynamic Simulations of Massive Main-sequence Stars. III. The Effect of Radiation Pressure and Diffusion Leading to a 1D Equilibrium Model
Authors: Mao Huaqing , Woodward Paul , Herwig Falk , Denissenkov Pavel A. , Blouin Simon , Thompson William , McDermott Benjamin
Published: November 2024

We present 3D hydrodynamical simulations of core convection with a stably stratified envelope of a 25 M
⊙ star in the early phase of the main sequence. We use the explicit gas-dynamics code PPMstar, which tracks two fluids and includes radiation pressure and radiative diffusion. Multiple series of simulations with different luminosities and radiative thermal conductivities are presented. The entrainment rate at the convective boundary, internal gravity waves in and above the boundary region, and the approach to dynamical equilibrium shortly after a few convective turnovers are investigated. We perform very long simulations on 8963 grids accelerated by luminosity boost factors of 1000, 3162 and 10,000. In these simulations, the growing penetrative convection reduces the initially unrealistically large entrainment. This reduction is enabled by a spatial separation that develops between the entropy gradient and the composition gradient. The convective boundary moves outward much more slowly at the end of these simulations. Finally, we present a 1D method to predict the extent and character of penetrative convection beyond the Schwarzschild boundary. The 1D model is based on a spherically averaged reduced entropy equation that takes the turbulent dissipation as input from the 3D hydrodynamic simulation and takes buoyancy and all other energy sources and sinks into account. This 1D method is intended to be ultimately deployed in 1D stellar evolution calculations and is based on the properties of penetrative convection in our simulations carried forward through the local thermal timescale.

Published: November 2024

Molecular hydrogen (H2) formation and dissociation are key processes that drive the gas life cycle in galaxies. Using the SImulating the LifeCycle of Molecular Clouds zoom-in simulation suite, we explore the utility of future observations of H2 dissociation and formation for tracking the life cycle of molecular clouds. The simulations used in this work include nonequilibrium H2 formation, stellar radiation, sink particles, and turbulence. We find that at early times in the cloud evolution H2 formation rapidly outpaces dissociation and molecular clouds build their mass from the atomic reservoir in their environment. Rapid H2 formation is also associated with a higher early star formation rate. For the clouds studied here, H2 is strongly out of chemical equilibrium during the early stages of cloud formation but settles into a bursty chemical steady state about 2 Myr after the first stars form. At the latest stage of cloud evolution, dissociation outweighs formation and the clouds enter a dispersal phase. We discuss how theories of the molecular cloud life cycle and star formation efficiency may be distinguished with observational measurements of H2 fluorescence with a space-based high-resolution far-UV spectrometer, such as the proposed Hyperion and Eos NASA Explorer missions. Such missions would enable measurements of the H2 dissociation and formation rates, which we demonstrate can be connected to different phases in a molecular cloud’s star-forming life, including cloud building, rapidly star forming, H2 chemical equilibrium, and cloud destruction.
The COS CGM Compendium. V. The Dichotomy of O vi Associated with Low- and High-metallicity Cool Gas at z < 1

Published: November 2024

We analyze the O vi content and kinematics for 126 H i-selected absorbers at 0.14 ≲ z ≲ 0.73 for which the metallicities of their cool photoionized phase have been determined. We separate the absorbers into 100 strong Lyα forest systems (SLFSs with 15 ≲ log N(H i) < 16.2) and 26 partial Lyman Limit systems (pLLSs with 16.2 ≤ log N(H i) ≤ 17.2). The sample is drawn from the COS CGM Compendium (CCC) and has O vi coverage in signal-to-noise ratio ≥ 8 Hubble Space Telescope/COS G130M/G160M QSO spectra, yielding a 2σ completeness level of

log
N

(O vi) ≥ 13.6. The O vi detection rates differ substantially between low-metallicity (LM; [X/H] ≤ −1.4) and high-metallicity (HM; [X/H] > −1.4) SLFSs, with 20% and 60% detection rates, respectively. The O vi detection frequency for the HM and LM pLLSs is, however, similar at ∼60%. The SLFSs and pLLSs without detected O vi are consistent with the absorbing gas being in a single phase, while those with O vi trace multiphase gas. We show that the O vi velocity widths and column densities have different distributions in LM and HM gas. We find a strong correlation between O vi column density and metallicity. The strongest (

N

(O vi) ≳ 14 most likely arise in the CGM of star-forming galaxies. Absorbers with weak O vi likely trace the extended CGM or intergalactic medium, while those without O vi likely originate in the intergalactic medium.
Discovery of a Dense Association of Stars in the Vicinity of the Supermassive Black Hole Sgr A*
Authors: Hosseini S. Elaheh , Eckart Andreas , Zajaček Michal , Britzen Silke , Bhat Harshitha K. , Karas Vladimír
Published: November 2024

We focus on a sample of 42 sources in the vicinity of the bow-shock source IRS 1W (N-source region), located at a distance of 6.″05 northeast of the supermassive black hole Sagittarius A* (Sgr A*), within the radius of 1.″35. We present the first proper-motion measurements of N sources and find that a larger subset of N sources (28 sources) exhibit a north–west (NW) flying angle. These sources can be bound by an intermediate-mass black hole (IMBH) or the concentration that we observe is due to a disk-like distribution projection along the line of sight. We detect the N sources in the H, K

s
, and

L
′

bands. The NW-ward flying sources could be a bound collection of stars. We discuss the tentative existence of an IMBH or an inclined disk distribution to explain the significant overdensity of stars. The first scenario of having an IMBH implies the lower limit of ∼104
M
⊙ for the putative IMBH. Our measurements for the first time reveal that the dense association of stars containing IRS 1W is a comoving group of massive, young stars. This stellar association might be the remnant core of a massive stellar cluster that is currently being tidally stripped as it inspirals toward Sgr A*. The second scenario suggests that the appearance of the N sources might be influenced by the projection of a disk-like distribution of younger He-stars and/or dust-enshrouded stars.

Published: November 2024

Studying the magnetic field properties on the solar surface is crucial for understanding the solar and heliospheric activities, which in turn shape space weather in the solar system. Surface flux transport (SFT) modeling helps us to simulate and analyze the transport and evolution of magnetic flux on the solar surface, providing valuable insights into the mechanisms responsible for solar activity. In this work, we demonstrate the use of machine learning techniques in solving magnetic flux transport, making it accurate. We have developed a novel physics-informed neural network (PINN)-based model to study the evolution of bipolar magnetic regions using SFT in one-dimensional azimuthally averaged and also in two dimensions. We demonstrate the efficiency and computational feasibility of our PINN-based model by comparing its performance and accuracy with that of a numerical model implemented using the Runge–Kutta implicit–explicit scheme. The mesh-independent PINN method can be used to reproduce the observed polar magnetic field with better flux conservation. This advancement is important for accurately reproducing observed polar magnetic fields, thereby providing insights into the strength of future solar cycles. This work paves the way for more efficient and accurate simulations of solar magnetic flux transport and showcases the applicability of PINNs in solving advection–diffusion equations with a particular focus on heliophysics.
The Linear Mixing Approximation in Silica–Water Mixtures at Planetary Conditions
Authors: Darafeyeu Valiantsin , Rimle Stephanie , Mazzola Guglielmo , Helled Ravit
Published: November 2024

The linear mixing approximation (LMA) is often used in planetary models for calculating the equations of state (EOS) of mixtures. A commonly assumed planetary composition is a mixture of rock and water. Here we assess the accuracy of the LMA for pressure–temperature conditions relevant to the interiors of Uranus and Neptune. We perform molecular dynamics simulations using ab initio simulations and consider pure water, pure silica, and 1:1 and 1:4 silica–water molecular fractions at a temperature of 3000 K and pressures between 30 and 600 GPa. We find that the LMA is valid within a few percent (< ∼5%) between ∼150 and 600 Gpa, where the sign of the difference in inferred density depends on the specific composition of the mixture. We also show that the presence of rocks delays the transition to superionic water by ∼70 GPa for the 1:4 silica–water mixture. Finally, we note that the choice of electronic theory (functionals) affects the EOS and introduces an uncertainty of the order of 10% in density. Our study demonstrates the complexity of phase diagrams in planetary conditions and the need for a better understanding of rock–water mixtures and their effect on the inferred planetary composition.
Contemporary Civil-Military Relations
Authors: Ivan MAJCHÚT
Published: November 2024

Civil-military relations are still an under-researched area in relation to the existence and deployment of armed forces.However, it is the factor that significantly influences the management of the state and the use of relevant power tools,including the armed forces. The aim of this paper is to carry out research of the fundamental factors affecting theestablishment, deployment and control of armed forces. The research was carried out using the methods of analysis, synthesis,comparison, abstraction, deduction and prediction. It was found that in democratic states there is a legislative framework forthe establishment, deployment and control of armed forces. However, each state has its peculiarities. Their mutualunderstanding is important especially in multinational operations. This can help in reducing differences of opinions and inachieving both political synergy and military interoperability. This paper can assist both civilian and military officials inunderstanding their place in civil-military relations and their competencies in managing the armed forces.
Cross-Cultural Comparisons for the Analysis of Disinformation in a Geopolitical Context: Case of Ukraine
Authors: Yuliia Turchenko
Published: November 2024

Cross-cultural comparisons are a valuable tool for analysing disinformation in a geopolitical context due to the increasing interconnectedness of the world and the spread of information across different cultures and societies. By examining how disinformation campaigns manifest and are perceived in various cultural contexts, researchers can gain insights into the underlying motives, tactics and effects of such campaigns. Disinformation has become a systemic challenge to society due to a combination of disruptive technological, political and sociological transformations of social spheres in a very short period. In addition, the geopolitical zeitgeist, which focuses on the vulnerability of democracies to structural changes in the security order and the risks of global interdependence, reinforces the tipping point effect.

Authors: Petr KELLNER  , Viktor NOVOTNÝ  , Petr ZAHRADNÍČEK  , Jiří NEUBAUER
Published: November 2024

This study investigates the influence of COVID-19 restrictions on first-year university students' physical fitness over five years, analyzing data from the University of Defence. The findings reveal a significant decline in first -semester performances in 2020/21, primarily attributed to students who did not undergo physical entrance exams and experienced a partial lockdown along with distant schooling. The class of 2021/22, despite similar conditions, achievedcomparatively better results, possibly due to increased control of students during distant schooling at the residence hall. Conversely, the period of 2019/20 saw the most substantial decline in physical performance, suggesting challenges in adapting to abrupt transitions to distant schooling. From these results, it is evident that factors such as physical entrance exams, in-person schooling, and supervision play crucial roles in improving physical performance among university students. These findings underscore the impact of pandemic-related disruptions on physical capabilities, offering insights for education and health policymakers aiming to support student well -being during unprecedented times.

The paper delves into the contemporary information security challenges within computer networks. It scrutinizes the existing methods of message packet routing, identifying several drawbacks associated with them. When examining issues concerning information security, it's crucial to consider the unique characteristics of this aspect of security. Security forms an integral part of information technologies, a field evolving at an unprecedented pace. The paper addresses the challenges associated with developing secure routing algorithms within Wide Area Network (WAN) environments. The paper presents and elucidates on novel secure routing algorithms characterized by a qualitatively innovative approach to resolving security concerns. Thanks to a novel suite of essential features in each variant of the proposed method, which includes specifying information about the communication network's structure, initial data regarding network nodes and users, and calculating integrated security metrics, secure routes between network nodes are meticulously selected from all available communication pathways among users. This ensures that network users are furnished with a secure route.The paper pertains to the realm of information communication and can serve as a valuable resource for planning or developing new network connections in networks like corporate intranets and extranets.

Design of Web GIS Application for Planning of Military River Crossing
Authors: Filip DOHNAL  , Šimon STRAKA  , David DUCHAN
Published: November 2024

Successful ground military operations necessitate thorough comprehension of the operational environment, particularly terrain and water features. This article advocates for the utilization of Geographic Information System (GIS) technology to develop a dynamic web application aimed at analyzing and planning watercourse crossings. By harnessing the capabilities of ArcGIS Pro and ArcGIS Online, the proposed application integrates hydrological and terrain data to provide comprehensive insights into the feasibility of crossing specific water obstacles under varying conditions. Key considerations include terrain characteristics, river channel profiles, and the tactical specifications of military vehicles. While the application is currently in the conceptual phase and awaits verification, its potential in enhancing operational planning for the Czech Armed Forces is underscored. This GIS-based approach promises to enhance decision-making processes by offering real-time, interactive support for evaluating and strategizing water obstacle crossings within military operations.
Infestation levels of Nodipecten subnodosus (Bivalvia: Pectinidae) by the borer Polydora sp. (Polychaeta: Spionidae) in Ojo de Liebre Lagoon, Mexican Pacific

Published: November 2024

The infestation of boring polychaetes can represent a serious problem for mollusks in natural populations and aquaculture. In the Mexican Pacific, their effects have been scarcely studied. So, this research aimed to analyze the infestation levels of Polydora sp. on Nodipecten subnodosus in the Ojo de Liebre Lagoon. Between May 2014 and October 2015, 639 specimens from four banks were collected to examine the spatial and temporal variations of the number of blisters by valve and their relationships with the scallop size. Around the lagoon mouth, the smaller scallops (<51 cm2) dominated, having the higher infestation percentages: Chocolatero: 88 ind (61%), Zacatoso: 86 ind (51%). In contrast, the larger scallops (51-89 cm2) were found in the inner lagoon, with smaller percentages of infestation: La Concha: 35 ind (21%) and El Datil: 29 ind (19%). The right valves, in closer contact with the bottom, were more infested than the left; those from Chocolatero and Zacatoso had more blisters (right 51-61%, left 14-15%), whereas in La Concha and El Datil both valves had fewer blisters (right 19-21%, left 6-8%). Larger scallops (51-89 cm2) from La Concha had low (5 ind) and medium (4 ind) infestation levels, and those smaller from Chocolatero (13-51 cm2) had high levels (34 ind). However, the relationship size scallop-infestation level needed to be clarified since larger scallops of El Datil also had high infestation levels (6 ind), and smaller specimens of Zacatoso showed lower (25 ind) and medium (27 ind) levels.
Tristan, le Morholt et le dragon. Du rituel initiatique au scénario romanesque
Authors: Grisward Joël H.
Published: November 2024

Les « Enfances Tristan » sur lesquelles s’ouvre la tragique histoire des amants de Cornouailles s’offre à première lecture comme une sorte de hors-d’œuvre confectionné à l’aide du montage plus ou moins hétéroclite de thèmes et de motifs divers, les uns héroïques, les autres énigmatiques, d’autres encore insolites voire burlesques. Or loin de constituer un simple et divertissant bric-à-brac, cette préhistoire à la tragique aventure sentimentale reproduit, dans son scénario, jusqu’au plus infime détail et avec une absolue fidélité le schéma narratif structuré, le parcours minutieusement préconstruit qui organise, sur le territoire des lndo-Européens, l’initiation et/ou la promotion du héros-guerrier type ! Dans ce cadre reçoivent sens et justification non seulement le premier « duel régulier » contre le Morholt et le combat contre le « grand serpent crêté », mais aussi le caractère « troisième » du héros, l’empoisonnement – à la fois souillure et danger – contrecoup d’un triomphe périlleux, la chaleur consécutive à Ia bataille et le plongeon dans la mare, l’ébréchure traîtresse et l’intervention féminine hostile… Ce type de scénario a été disséqué pour l’épopée irlandaise, I’Histoire romaine voire le Mahabharata par Georges Dumézil, lequel fournit, à travers des parallèles saisissants, un abondant et convaincant matériel comparatif.

Published: November 2024

The challenges of maintaining an effective and sustainable healthcare workforce include the recruitment and retention of skilled nurses. COVID-19 exacerbated these challenges, but they persist beyond the pandemic. We explored the impact of work-related quality of life and burnout on reported intentions to leave a variety of healthcare professions including nursing. We collected data at five time-points from November 2020 to February 2023 via an online survey. The validated measures used included the Copenhagen Burnout Inventory and Work-Related Quality of Life (WRQoL) scale; with subscales for Job-Career Satisfaction, General Wellbeing, Control at work, Stress at work, Working conditions, and Home-work interface. Our findings showed that 47.6% of nursing respondents (n = 1780) had considered changing their profession throughout the study period, with the 30–39-year age group most likely to express intentions to leave. Regression analysis reveale that for WRQoL, lower general wellbeing and job-career satisfaction scores predicted intentions to leave when controlling for demographic variables (p < 0.001). When burnout was added to the regression model, both work-related and client-related burnout were predictive of intentions to leave (p < 0.001). These findings highlighted that significant numbers of nurses considered leaving their profession during and shortly after the pandemic and the need for interventions to improve nurses' wellbeing and reduce burnout to improve their retention.

Using data collected for my doctoral research in Gabon, and building upon social science research on witchcraft and madness, I set out to reflexively analyse my positionality as a researcher and the way in which fieldwork relations influenced the construction of my object of study. Taking into account that in Gabon, especially in the context of Fang socio-religious practices related to Bwiti [the invisible], therapeutic processes designed to care for madness are conveyed with and reinforce a certain vision of the mad person as dangerous, this reflexive exercise serves as an opportunity to examine the feelings of anxiety which the presence of mad persons arouse in me, and the impact of this powerful emotion on my research process. The reflexivity proposed here consists of showing how dealing with this fear revealed the intimate ramifications of madness, brought to light because of my cultural and familial proximity to it. Furthermore, it demonstrates how this fear forced me to consider these affective exchanges as materials to be made use of, alongside the research data collected in the therapeutic village of Endedang Ening.

In response to the evolving e-commerce landscape, the study investigates changing patterns of social networking site (SNS) usage during a pandemic. Grounded in the interaction of the person-affect-cognition-execution model for addictive behaviors and the appraisal and coping theory, it explores the depth and extent of SNS usage. Specifically, the study examines the moderated mediating effect of perceived stress (PS) and fear of missing out, with risk mitigation behavior as a moderator. With data from a nationwide survey in Korea with 760 responses, results show that risk mitigation behavior moderates the relationship between infection threat and PS, while PS and fear of missing out mediate the effect of infection threat on SNS usage. The moderated mediation of PS was significant, shedding light on the complex psychological mechanisms that drive SNS behavior during global crises. The findings deepen understanding of how stress and coping strategies shape SNS engagement in response to crisis.

Common molecular basis of aging and cancer dynamics: complex interactions among age, diseases, external stressors, and environmental factors
Authors: Sharma Nilesh Kumar
Published: November 2024

There are incremental efforts to understand the multifaceted aspects of aging, particularly focusing on its biological interplay with various environmental stressors and diseases such as cancer. The concept of biological age, which is distinct from chronological age, and its importance in predicting disease onset and mortality patterns are emphasized. Furthermore, exploration of the reversible nature of biological aging under different stress conditions, such as surgery, pregnancy, and diseases such as cancer and coronavirus disease 2019, is intriguing. This narrative review attempts to address the potential impact of viral infections such as severe acute respiratory syndrome coronavirus 2 and the altered landscape of diseases such as cancer on biological aging and their interconnected relationships. Additionally, it also touches upon the influence of emerging technologies, particularly artificial intelligence-driven machines, on aging dynamics, prompting further research in this area. This article may provide insight into a comprehensive framework for interdisciplinary research to better understand the complex interactions among age-related dynamics, diseases, external stressors, and environmental factors, with implications for future interventions and healthcare strategies.
Recent advances in biomaterial design for nerve guidance conduits: a narrative review

Published: November 2024

Researchers have made significant strides in developing biomaterials for nerve guiding conduits, exploring natural polymers like chitosan, collagen, and silk, along with synthetic counterparts such as silicone, poly(lactic-co-glycolic acid), polycaprolactone, and poly(L-lactic acid). Each material offers distinct benefits, necessitating further study for refinement. Diverse conduit designs, including hollow/non-porous, porous, grooved, multi-channel, and fiber/hydrogel-filled conduits, have been created. Multi-channel and aligned fiber designs stand out for providing effective topographical cues guiding axon formation. Various manufacturing methods, from solvent casting to three-dimensional printing techniques like electrohydrodynamic jet and digital light processing, enable scaffold manipulation. Positive outcomes in laboratory (in vitro) and live animal (in vivo) experiments indicate the effectiveness of biomaterial-based conduits in connecting nerve gaps and promoting regeneration. However, research remains predominantly in the preclinical phase, with challenges like inadequate mechanical characteristics and the absence of biological signals. Addressing these constraints requires material refinement and the introduction of biological functionality. Future prospects involve intelligent conduits using nanocomposite biomaterials, stem cells, controlled release of neurotrophic factors, and integration of electrical and optical stimulation. Comprehensive preclinical validation is crucial before clinical translation. Despite advancements, further study is essential to fully leverage biomaterials as nerve autograft substitutes, with multidisciplinary collaboration key to continued progress in this promising field. The main goal is to present a thorough overview of the most recent developments, cutting-edge research gaps, and future prospects in the engineering and design of biomaterial-based nerve guiding conduits for the repair of peripheral nerve injury.
Noninvasive neurostimulation promotes working memory performance in older adults: a systematic review

Published: November 2024

Working memory is a core component of high-level cognitive functions. A key feature of cognitive decline in older adults is the impairment of working memory capacity, which is also observed in many clinical conditions. In recent years, noninvasive neurostimulation techniques have garnered extensive research attention for their potential to enhance human cognitive function, particularly in older adults. This review focuses on several advanced noninvasive neurostimulation techniques for working memory in older adults. A systematic search of the PubMed and Google Scholar literature databases was conducted, covering research papers published from 2013 to 2023. This review identified 19 articles on transcranial electrical stimulation, 6 on transcranial magnetic stimulation, and 2 on transcranial photobiomodulation techniques that met the inclusion criteria. These results suggest that transcranial electrical stimulation, especially transcranial alternating current stimulation and transcranial direct current stimulation, can improve working memory performance in healthy older adults. Transcranial direct current stimulation combined with cognitive training improves functional connectivity between relevant brain regions in addition to performance gains. Transcranial random noise stimulation, transcranial magnetic stimulation, and transcranial photobiomodulation also have the potential to improve working memory. Further research is needed to understand the neural mechanisms involved and optimize stimulation parameters. In addition, emerging techniques such as transcranial focused ultrasound may offer promising solutions for future studies on working memory enhancement in older adults.
