Legal Protection of Foreign Workers (TKA) in Indonesia
Authors: Arif Budiman Lubis  , I Nyoman Budiana
Published: February 2025

The primary objective of this study is to investigate the legal safeguards in place for foreign workers in Indonesia, also known as TKA. The study employed a normative legal research methodology, incorporating statutory, case-based, and conceptual approaches. Judges base their decisions on Article 62 of Labor Law Number 13 of 2003, ensuring that their rulings abide by the law to promote legal certainty and justice. Labor protection is a form of recognition of the rights of workers/laborers as human beings who must be treated humanely. In a country based on law (rechstaat), the mandate for the laws and regulations to be applied correctly is that judges must side with justice (moral justice).

Over three decades of reverberation mapping (RM) studies on local broad-line active galactic nuclei (AGNs) have measured reliable black hole (BH) masses for >100 AGNs. These RM measurements reveal a significant correlation between the Balmer broad-line region (BLR) size and AGN optical luminosity (the R–L relation). Recent RM studies for AGN samples with more diverse BH parameters (e.g., mass and Eddington ratio) reveal a substantial intrinsic dispersion around the average R–L relation, suggesting that variations in the broadband spectrum, driven by accretion parameters and other factors such as the cloud distribution and inclination, significantly influence the measured R–L relation. Here we perform a detailed photoionization investigation of expected broad-line properties as functions of accretion parameters using AGN continuum models from qsosed. We compare theoretical predictions with observations of a sample of 67 z ≲ 0.5 reverberation-mapped AGNs with rest-frame optical and UV spectra in the moderate-accretion regime (Eddington ratio λ
Edd ≡ L/L
Edd < 0.5). The UV/optical line strengths and their dependences on accretion parameters are reasonably well reproduced by the locally optimally emitting cloud photoionization models. We provide quantitative recipes using optical/UV line flux ratios to infer the unobservable ionizing continuum. Additionally, photoionization models with universal values of ionization parameter (

) can qualitatively reproduce the observed global R–L relation for the current RM AGN sample. However, such models fail to reproduce the observed decrease in BLR size with increasing L/L

CH3OH Thermal Lines Traces 6.7 GHz CH3OH Maser Variation of High-mass Protostar G353.273+0.641
Authors: Song Shi-Min , Chen Xi , Liu Sheng-Yuan , Liu Jun-Ting
Published: February 2025

This study reports an analysis of the 6.7 GHz CH3OH maser in the high-mass protostar G353.273+0.641 (G353), utilizing data from the Tianma Radio Telescope. G353 is a possibly periodic variation in the flux density of the maser with a period of ∼330 days. Our analysis of Atacama Large Millimeter/submillimeter Array archival data identified 44 CH3OH transitions within the gas envelope surrounding the protostar. The CH3OH envelope exhibited non–local thermodynamic equilibrium (LTE) conditions during the increase phase of the flux density of the maser, then transitioning to LTE (T ∼ 380 K) during the decay phase of the maser. This phenomenon is likely attributed to the recurrent heating of the protostellar envelope through heat waves, which are generated by the periodic luminosity oscillations of the central high-mass protostar. The propagation velocity of the heat wave is gauged to be  ∼0.02c. These results emphasize the significance of integrating the variations in 6.7 GHz CH3OH masers with their surrounding circumstellar environments to advance our comprehension of high-mass star formation mechanisms.
The Impact of Bar-induced Noncircular Motions on the Measurement of Galactic Rotation Curves
Authors: Liu Jie , Li Zhi , Shen Juntai
Published: February 2025

We study the impact of bar-induced noncircular motions on the derivation of galactic rotation curves (RCs) using hydrodynamic simulations and observational data from the PHANGS-ALMA survey. We confirm that noncircular motions induced by a bar can significantly bias RCs derived from the conventional tilted-ring method, consistent with previous findings. The shape of the derived RC depends on the difference in position angle (Δϕ) between the major axes of the bar and the disk in the face-on plane. For

, noncircular motions produce a bar-induced “dip” feature (rise–drop–rise pattern) in the derived RC, which shows higher velocities near the nuclear ring and lower velocities in the bar region compared to the true RC (RCtrue). We demonstrate convincingly that such dip features are very common in the PHANGS-ALMA sample of barred galaxies. Hydrodynamical simulations reveal that the “dip” feature is caused by the perpendicular orientation of the gas flows in the nuclear ring and the bar; at low

streamlines in the nuclear ring tend to enhance V

Furthermore, we propose a straightforward method to implement a first-order correction to the RC derived from the tilted-ring method. Our study is the first to systematically discuss the bar-induced “dip” feature in the RCs of barred galaxies by combining both simulations and observations.

Published: February 2025

The James Webb Space Telescope (JWST) has opened up a new window to study highly reddened explosive transients. We present results from late-time JWST follow-up spectroscopic observations with NIRSpec and MIRI-LRS of the intermediate-luminosity red transient (ILRT) AT 2019abn. ILRTs represent a mysterious class of transients that exhibit peak luminosities between those of classical novae and supernovae and that are known to be highly dust obscured. Similar to the prototypical examples of this class of objects, NGC 300 2008-OT and SN 2008S, AT 2019abn has an extremely red and dusty progenitor detected only in pre-explosion Spitzer/IRAC imaging at 3.6 and 4.5 μm and not in deep optical or near-infrared Hubble Space Telescope images. We find that late-time observations of AT 2019abn from NEOWISE and JWST are consistent with the late-time evolution of SN 2008S. In part because they are so obscured by dust, it is unknown what produces an ILRT, with hypotheses including high-mass stellar merger events, nonterminal stellar outbursts, and terminal supernova explosions through electron capture in super-AGB (SAGB) stars. Our JWST observations show strong mid-IR class C polycyclic aromatic hydrocarbon features at 6.3 and 8.25 μm typical of carbon-rich post-AGB sources. These features suggest that the dust around AT 2019abn is composed of carbonaceous grains, which are not typically observed around red supergiants. However, depending on the strength and temperature of hot bottom burning, SAGB stars may be expected to exhibit a carbon-rich chemistry. Thus, our JWST observations are consistent with AT 2019abn having an SAGB progenitor and exploding as an electron-capture supernova.
Second gradient thermoelasticity with microtemperatures
Authors: Ieşan Dorin , Quintanilla Ramón
Published: February 2025

This research was concerned with a linear theory of thermoelasticity with microtemperatures where the second thermal displacement gradient and the second gradient of microtemperatures are included in the classical set of independent constitutive variables. The master balance laws of micromorphic continua, the theory of the strain gradient of elasticity, and Green-Naghdi thermomechanics were used to derive a second gradient theory. The semigroup theory of linear operators allowed us to prove that the problem of the second gradient thermoelasticity with microtemperatures is well-posed. For the equations of isotropic rigids, we presented a natural extension of the Cauchy-Kovalevski-Somigliana solution of isothermal theory. In the case of stationary vibrations, the fundamental solutions of the basic equations were obtained. Uniqueness and instability of the solutions were obtained in the case of antiplane shear deformations.

In this paper, we study space-time decay rates of a nonconservative compressible two-phase flow model with common pressure in the whole space $ \mathbb{R}^{3} $. Based on previous temporal decay results, we establish the space-time decay rate of the strong solution. The main analytical techniques involve delicate weighted energy estimates and interpolation.

Perceptions et pratiques de gestion forestière en site Natura 2000 en France : Une approche par photos-questionnaire
Authors: Brahic Élodie , Deuffic Philippe
Published: February 2025

En France et en Europe, le rapport ambigu que les propriétaires forestiers entretiennent avec le dispositif Natura 2000 a donné lieu à de nombreuses enquêtes qui en soulignent une réception plutôt négative. Cependant, peu d’entre elles s’intéressent à la façon dont ces espaces sont gérés une fois le site désigné et alors que très peu de contrats sont signés. Notre étude vise à cerner la façon dont les propriétaires forestiers entrevoient la gestion de ces espaces vingt ans après la mise en place de ce dispositif. Nous faisons l’hypothèse que l’écologisation des pratiques modifie partiellement le regard qu’ils portent sur les enjeux environnementaux, et que la matérialité, la configuration et la dynamique des lieux influencent leurs modes de gestion. Basée sur sept photographies de milieux caractéristiques de la vallée du Ciron (peuplements de pin maritime, de feuillus, zones humides, ripisylves, bois morts), notre étude vise à apprécier la perception de ces paysages au regard de plusieurs critères (esthétique, entretien, naturalité, sécurité, fonctionnement écologique et diversité biologique) et à identifier les actions que les enquêtés envisageraient sur ces milieux. Le traitement statistique des données d’enquête permet d’identifier quatre profils de propriétaires : les partisans de la libre évolution, ceux qui préfèrent une gestion multifonctionnelle, et les adeptes d’une gestion plus ou moins active, à travers des degrés divers d’extraction de bois. Si Natura 2000 continue de susciter quelques inquiétudes et critiques chez les propriétaires forestiers, notre étude montre que c’est aussi un dispositif qui s’est normalisé, qui leur laisse des marges de manœuvre suffisantes pour qu’ils y déclinent un bouquet de pratiques environnementales personnalisées. La zone protégée apparaît ainsi comme un lieu d’apprentissage réciproque où l’ensemble des communautés de pratiques s’approprient progressivement le dispositif.

Published: February 2025

Silica can be utilized as a DSSC anti-reflection layer material due to its wide storage, low refractive index, and harmlessness. Pumice is a volcanic shaft rock made of silica and alumina. Here, silica was extracted from pumice at 800°C and various aging times of 18 and 24 hours to be used as an anti-reflection in the fabricated DSSC. The extraction results were characterized by XRD and SEM-EDX, revealing that the highest silica content of 79.56% was obtained at the aging time of 24 hours. It was then deposited on the opposite of the FTO active area using the spin coating with varied layer numbers (1 and 2). A UV-Vis spectrophotometer was performed on the sample to observe the transmittance of the FTO without and with silica anti-reflective coatings. It showed that the 1 layer of silica had the highest transmittance. The DSSC performance was tested by an I-V meter to determine current, voltage, and efficiency. It demonstrated that, as it had the highest transmittance value, the fabricated DSSC with 1 layer of silica efficiency by 0.15% compared to the one without anti-reflection coating. Therefore, it could be concluded that the addition of anti-reflection could improve the efficiency of DSSC.Keywords: Pumice, Silica anti-reflection layer, DSSC
Study of Gelation Processes in Flame Retardant Compositions of the SiO2 Sol System – A Phosphate-Containing Additive
Authors: Lysak Nataliia , Skorodumova Olga , Chernukha Anton , Kochubei Viktoria , Sotiriadis Konstantinos
Published: February 2025

One of the promising directions for ensuring the fire resistance of wooden building materials is the development of silicon phosphate compositions, thanks to which the formation of a protective layer is possible, which effectively prevents the spread of fire. The paper examines the possibility of using orthophosphate acid as a modifying additive for silicic acid sols. The influence of H3PO4 concentration on the rheological characteristics of the studied sols was determined. Sols with small amounts of orthophosphate acid (1–2%) lost their fluidity in the interval of 45–70 minutes. Increase of the additive content to 8% led to a sharp increase in optical density values and extended the survivability interval of the sol to 24 hours. Coatings based on gels with 1–2% orthophosphate acid were elastic, but increasing the content of the additive led to the formation of hard, inelastic coatings.According to the results of infrared (IR) spectroscopy, the effect of orthophosphate acid on the nature of polycondensation was confirmed. The degree of polycondensation was estimated by the ratio of intensity (I) and band width (d) at 1050 cm–1, which corresponds to the vibrations of Si-O-Si bonds. Based on the comparison of I/d indicator values, the formation of linear siloxane chains was confirmed in the case of the use of small H3PO4 additions. Linear polycondensation ensures greater homogeneity of the gel, which was confirmed by IR spectroscopy of gels heat-treated at 800 °C and by microscopic observations. The coating on the wood surface, based on a fire-resistant silica-containing composition with small additions of orthophosphate acid, had the most uniform and continuous structure.
Isaiah 3:16–23: Dress, pride, ostentatious items or syncretism?
Authors: Nyarko-Mensah Paul , Human Dirk J.
Published: February 2025

The study investigated Isaiah 3:16–23 using the historical-grammatical methodology for the following reasons: to explore the author’s aim in writing the passage, ascertain the socio-psychological significance of dress and outward appearance, determine whether the items listed are exclusively female dresses and examine the contribution of the women of Zion to national sin. Does the passage prohibit the use of jewellery? Isaiah rebuked the women for their pride in appearance, suggesting that their sin was a haughty spirit, expressed through their manner of walking and the use of luxurious items. The items listed include both male and female articles of dress and are not exclusively female dresses. Also, the list included items which had their origin in the cult and magic system of their Canaanite neighbours. Outward appearance can reflect one’s socio-economic status, as well as religious, moral and cultural values. Dress can influence how a person is perceived by others and can also affect one’s values.

Authors: Shah Jeet Prakashkumar , Dsouza Jenifa Nora , Patil Nalini Mangesh
Published: February 2025

Background:

Noncompliance with prescribed antipsychotic medications significantly increases the risk of illness exacerbation and rehospitalization in patients with schizophrenia. One way to enhance drug compliance involves identifying key factors contributing to poor compliance and enabling the development of effective strategies to improve patient’s adherence to medications. Therefore, the aim of this study was to assess factors responsible for drug noncompliances and their associations with clinical variables.

Methodology:

This cross-sectional study was conducted at the Mahatma Gandhi Mission Medical College and Hospital, with approval from the Institutional Ethical Committee. A total of 47 subjects diagnosed with schizophrenia were included, and their sociodemographic information and consent forms were collected. Noncompliance was evaluated using a Rating of Medication Influences Scale. The severity of the disease was assessed using the Positive and Negative Syndrome Scale (PANSS).

Results:

A total of 47 patients participated, of whom 15 were male (31.91%) and 32 were female (68.09%). In our study, the factor that showed the strongest association with medication compliance was the perceived daily benefit. Significant associations were observed between drug noncompliance and the younger age group, unemployment, and a high positive PANSS score. The factors associated with antipsychotic drug noncompliance were denial of illness (χ2 = 35.6), stigma (χ2 = 12.97), substance abuse (χ2 = 15.55), and the belief that current medication is unnecessary (χ2 = 36.75).

Conclusion:

Patients with schizophrenia commonly demonstrate a high prevalence of medication nonadherence. Intervention strategies that prioritize patient education about their illness, prescribed medications, and potential side effects have shown promise in enhancing adherence to antipsychotic medication regimens.
How thyroid hormone disorder affect the expression of genes related to neurodegeneration in the hippocampus tissue of rats: An experimental study
Authors: Altunkaya Melek , Babur Ercan , Tufan Esra , Süer Cem , Dursun Nurcan
Published: February 2025

Background:

Thyroid hormones (THs) have important effects on many organ systems, including the hippocampus, by modulating gene transcription. Therefore, deviations from the normal reference range of this hormone cause vital changes. However, it is not well understood how these hormones affect the expression of genes involved in the Akt1/Gsk3ß signaling pathway in hippocampus tissue. The study investigated the changes in gene expression in eight genes related to neurodegeneration in the hippocampus tissue of rats with TH disorder (Gsk3ß-mRNA, Cdk5-mRNA, Akt1-mRNA, Mapt-mRNA P35 [Anxa]-mRNA, Capn1-mRNA, Bace1-mRNA, and Psen2-mRNA).

Methods:

Twenty-two male rats were split into three groups as control, hypothyroidism, and hyperthyroidism. Propylthiouracil was given in drinking water for 21 days to induce hypothyroidism. L-thyroxine was administered for 21 days to induce hyperthyroidism. The levels of genes in the hippocampus were measured with the reverse transcription-polymerase chain reaction method.

Results:

While free thyroxine (fT4) levels in blood plasma were found to be lower in the hypothyroidism group than in the control group, fT4 levels in blood plasma were found to be higher in the hyperthyroidism group. The mRNA expression levels of Cdk5, Mapt, P35, Akt1, Psen2, and Bace1 genes evaluated in hippocampus tissue showed significant differences between the groups.

Conclusion:

THs are essential for the expression of certain genes, and these genes need to be expressed within a certain range for the body to function properly. Changes in hormone levels can partially change the expression of Akt1/Gsk3ß-mRNA, which is also associated with learning and memory.

Published: February 2025

Medical education plays a pivotal role in ameliorating health-related outcomes by preparing health-care professionals with the desired knowledge, skills, and attitudes necessary to deliver effective patient-centered care. The purpose of the current review is to explore the role of medical education in rural areas, identify the potential challenges in the implementation, and propose suitable measures to overcome these challenges. The delivery of medical education in rural areas is expected to address the disparities in health-care delivery by serving people in underserved areas, thereby reducing the urban–rural divide. This is accomplished by ensuring timely access to medical services, resulting in the promotion of early diagnosis and better management of the disease. The process of delivery of medical education in rural settings has been associated with multiple challenges that must be systematically dealt with to improve the overall outcomes. In conclusion, promoting access to medical education in rural areas is a crucial step to establishing a robust and equitable health-care system that will aid in the attainment of universal health coverage. However, the need of the hour is to overcome the existing challenges to empower aspiring health-care professionals from rural backgrounds and also contribute to the overall health and well-being of underserved communities.

Published: February 2025

We present a 28-year-old booked G1P0 at 35 weeks scheduled for cesarean section to highlight the challenges with the anesthetic management of rheumatoid arthritis (RA) in a recently diagnosed parturient. She presented with a 4-day history of insidious multiple joint pains with high-grade fever. The joint pain started from the shoulder and affected mouth opening and neck movement. Her past medical history revealed that she had been on fertility treatment for reproductive difficulties. An assessment of early-onset RA in a booked nulliparous was made by the rheumatologist. On preoperative assessment for elective cesarean section, she reported a low-pitch hoarseness of voice following the onset of the flitting joint pains. The physical examination revealed a young woman, distressed and febrile to touch (38.6°C). There was mild tachycardia (heart rate = 102), regular, and good volume. The systolic blood pressure was 139/82 mmHg with first and second heart sounds only. The abdomen was at a fundal height of about 38 weeks. The fetal heart sounds were heard and regular. The airway examination indicated adequate mouth opening (4 cm), limited neck movement, and Class 3 Mallampati view. Prehydration was done with 0.9% saline 1000 mL, and spinal anesthesia was induced through the L3/4 interspace with a 25G pencil-point spinal needle The spinal medications, hyperbaric bupivacaine 9 mg + fentanyl 15 μg, were instilled. The sensory level was determined to be at T4. A set of twins was delivered with Apgar scores as follows, twin 1 (8/1, 9/5) and twin 2 (8/1, 9/5) by the attending neonatologist. The third stage was managed with oxytocin 5 i.u. bolus and 35 units in 500 mL of 0.9% to run at 100 mL/h. She was discharged on the 4th day postpartum having made remarkable improvement with the joint pain and movement. The postnatal clinic visit revealed a healthy mother and babies.

Published: February 2025

ABSTRACT

Background:

Upper gastrointestinal endoscopy (UGIE) is a crucial diagnostic and therapeutic procedure for various gastrointestinal conditions. However, it frequently induces significant anxiety and physiological disturbances in patients, which may affect procedural outcomes. Mind-body therapy has been proposed as a non-pharmacological intervention to mitigate these adverse effects.

Objective:

This study aimed to evaluate the effectiveness of mind-body therapy in improving psychological and physiological outcomes among patients undergoing UGIE.

Methods:

A randomized controlled trial was conducted at Rajiv Gandhi Government General Hospital, Chennai. Participants were assigned to either an experimental group receiving mind-body therapy or a control group receiving standard care. The mind-body therapy included video-assisted education, breathing exercises, and the Mendelsohn maneuver. Anxiety levels and physiological parameters were assessed pre- and post-intervention.

Results:

Patients in the experimental group exhibited significantly reduced anxiety levels and improved physiological stability compared to the control group. Statistical analysis revealed a meaningful association between mind-body therapy and enhanced patient comfort, with improvements in heart rate, blood pressure, and respiratory stability.

Conclusion:

Mind-body therapy, incorporating video-assisted education, breathing exercises, and the Mendelsohn maneuver, is an effective non-pharmacological intervention for reducing anxiety and enhancing physiological stability in patients undergoing UGIE. These findings support the integration of mind-body interventions into routine endoscopic care to improve patient outcomes. Future research should explore the long-term benefits and broader applicability of such interventions in endoscopic and other invasive procedures.

Authors: Subaraja Mamangam , Hillary V Edwin , Savarimuthu Ignacimuthu
Published: February 2025

Background & objectives:

Aedes aegypti mosquitoes are vectors for dengue, Zika, Chikungunya, and yellow fever viruses, which threaten over half the world's population. Therefore, new techniques are needed to control vector mosquitoes. The present study aimed to control female A. aegypti by targeting 3β-hydroxysteroid dehydrogenase (3β-HSD) and ecdysone receptor (EcR), which could potentially disrupt egg development, using sulfasalazine (SSZ)-double-stranded RNA (ds-RNA) nanoparticles (NPs).

Methods:

The SSZ-dsRNA NPs are characterized by light microscopy, field emission scanning electron microscopy, atomic force microscopy, raman spectroscopy, and fourier-transform infrared spectroscopy analysis. Next, 40 pl of SSZ, dsRNA, and SSZ-dsRNA NPs individually were injected into eggs of Ae. aegypti. Finally, the temporal gene expression levels of 3β-HSD and EcR genes were assessed using quantitative reverse transcription polymerase chain reaction (qRT-PCR).

Results:

The mortality rate and sterility were significantly increased (p<0.05), and the percentage of fecundity and viable progeny (p<0.05) showed effective results when exposed to SSZ-dsRNA compared to control eggs. In addition, the Sf9 cell line also confirmed the downregulation of the m-RNA 3β-HSD and EcR successfully when exposed to SSZ-dsRNA.

Interpretation & conclusion:

The current study proves for the first time that SSZ-dsRNA NPs can be used broadly for 3β-HSD and ECR gene silencing in mosquitoes. The use of this NPs SSZ-dsRNA complex in mosquito eggs leads to reduced fecundity in Ae. aegypti. This method will open a new door for mosquito control, which can be explored and utilized with future comprehensive research for better results. This method is not only limited to the mosquito species like Ae. Aegypti, it can also be tried with different mosquitoes as well as other insect species that cause harm to humans as pests of crops or vectors of various diseases.

Debris flow is one of the most common geological disasters in Vietnam, occurring in mountainous areas and causing catastrophic impacts on both the economy and human lives. This article shows the results of a debris flow simulation that took place on August 5, 2023, in Trong La village, Ho Bon commune, Mu Cang Chai district, Yen Bai province, through an empirical model called LAHARZ and digital elevation model (DEM). The debris flow also was assessed for damage to the built-up area. The LAHARZ model is based on empirical equations that were derived from historical debris flood statistics. The equations include A = 0.05 V^(2⁄3) and B = 200 V^(2⁄3), in which A is the cross-sectional area, B is the planimetric area, and V is the volume. This study uses drone images and digital elevation model with 0.5m spatial resolution, which were created on August 12, 2023, by using the Phantom 3 Professional drone. The debris flow's source area is roughly 78104 m2, corresponding to a volume of 8,000÷10,000 m3. For this reason, the LAHARZ model is simulated with volumes of 5,000; 8,000; 10,000; 15,000 and 20,000 m3. LAHARZ simulation results were validated by comparing them to field survey evidence. The result shows that the model results are quite similar to the actual inundated area with TPR and TS values ​​being 0.717 and 65.9%, respectively. This study also demonstrates that the false irregular edges in the delineated inundation zones supposedly originated because of a lack of DEM accuracy. The LAHARZ model simulation has many advantages in terms of time and the few parameters used, which enable rapid evaluation of debris flow scenarios.
Modeling and Suppression of Inhomogeneous Intensity Edible Bird Nest Images for Impurity Segmentation Using β-Variational Autoencoder
Authors: Khairul Firdaus Mohd Talib  , Hasnida Ab-Samat  , Lai Hoong Cheng  , Kin Sam Yen
Published: February 2025

This study proposes a β-variational autoencoder (β-VAE) method to address intensity inhomogeneity (IIH) in edible bird’s nest (EBN) images, which creates an uneven intensity that obscures fine impurity details and reduces segmentation accuracy. First, the β-VAE is used to learn the feature distribution of EBN images by mapping them into a latent space. This latent space is then disentangled through selective filtering and penalization of specific latent dimensions. This unsupervised learning approach effectively captures and isolates IIH in EBN images. Additionally, enabling precise segmentation of EBN and impurities without requiring annotated datasets. It also enhances robustness in handling unseen image instances. The proposed method achieves an intersection over union of 73.08% (equivalent to a Dice coefficient of 84.44%), surpassing existing segmentation techniques. By resolving IIH, this method improves the reliability and adaptability of automated EBN inspection systems for practical applications.
Risk-Aware Multi-Agent Advantage Actor-Critic Based Resource Allocation for C-V2X Communication in Cellular Networks
Authors: Irshad Khan  , Manjula Sunkadakatte Haladappa
Published: February 2025

Intelligent transportation systems have emerged promisingly for industries to enable automated and safe driving. However, to satisfy reliability, environmental sustainability, and overall performance, deep reinforcement learning requires massive energy consumption with its computational demands. In this research, the risk-aware multi-agent advantage actor-critic (RA-MA-A2C)-based resource allocation (RA) is proposed for the cellular-vehicle-to-everything (C-V2X) network. The RA-MA-A2C considers collision risk when allocating resources such as frequency and power. By integrating risk assessment into the decision-making process, the RA-MA-A2C adjusts RA to mitigate collision risks and thereby increases the system’s effectiveness. The RA-MA-A2C’s performance is evaluated in terms of the success rate, completion time, vehicle-to-infrastructure link sum rate, and vehicle-to-vehicle links probability. The RA-MA-A2C demands 108 ms completion time with a 98.81% success rate, surpassing the performance of the existing offloading resource allocation-based deep reinforcement learning (ORAD) method.
NASILJE KAO OBLIK DRUŠTVENOSTI – REPRODUKCIJA KULTURNOG OBRASCA KROZ OBRAZOVANJE
Authors: Pavlović Nikola R.
Published: February 2025

Taking into account the tragic events of mass murders that took place at the beginning of this year, in which young people and children almost exclusively participated, this paper will deal with the problem of violence as a form of sociality, that is, its reproduction through a cultural pattern. The
paper tries to analyze the problem on a deeper, structural level, taking into ac-
count the socio-economic-political context of the area being investigated, as well
as the increased rate of mass murders in the community as a phenomenon that
can be an indicator of a certain social pathology.
When we talk about concrete, Serbian society, specific forms of violence
such as mass murders are becoming much more frequent since social-econom-
ic-political changes after 2000. This type of violence is also indicative for the
reason that mostly an alienated individual commits violence against the com-
munity, the closest environment, family, relatives, friends, fellow citizens, which illustrates the state of anomie and “social confusion”, which is related to a suddenly changing way of life and cultural pattern.
PESIMIZAM U POPULARNOJ KULTURI
Authors: Rajak Nemanja
Published: February 2025

The aim of this paper is to explore the feeling of “wrongness of
existence” through popular culture, excluding the propaganda influences of
pop-politics and pop-ideology in cultural contents, as well as various forms of
“soft power”. The focus will be on the cracks of the culture through which the
feeling of hopelessness, fatigue and the inevitable end of a civilization perme-
ates. Through the analysis of the television series True Detective, the movie Jok-
er, the literature of Michel Houellebecq and the music of Lana Del Rey, we will
explore the core of pessimism in contemporary pop culture.

Authors: Putri Amelia Ivanka , Lutfillah Novrida Qudsi , Djuharni Darti
Published: February 2025

This research is based on the phenomenon of new investment trends by looking for which investment instrument is the best of four instruments, namely Antam Gold, LQ45 Shares, Reksa Dana, and Bitcoin Cryptocurrency. The research method used is a quantitative method with a comparative descriptive research type. The Sharpe, Treynor and Jensen index approaches are used to evaluate the performance of four investment instruments. the total sample size is 192 data. The results showed that LQ45 stocks produced the best performance during the Covid-19 pandemic. This condition is because LQ45 stocks can generate returns that are greater than the risk. The high return generated by LQ45 stocks even during the covid-19 pandemic was due to sectors that actually strengthened during the covid-19 pandemic. In addition, LQ45 stocks consist of stocks from the most liquid companies and have the largest market capitalisation so that these companies are resistant to crises.
Blind Spots in Crowds, Masses, and Multitudes
Authors: Teller Katalin
Published: February 2025

The brief historical overview comprises an account of classical crowd theories and their contemporary metamorphoses to contextualize the thematic section of the journal. Regarding the proverbial “age of the crowd” of the late nineteenth and twentieth centuries in Europe, a variety of attempts of conceptualization proved controversial but productive. Hyppolite Taine, Scipio Sighele, or Gustave Le Bon approached the phenomenon dominantly in psychological terms foregrounding the destructive elements of mass dynamics. In the interwar period, however, a first wave of differentiation might be detected, insofar as younger academic sub-disciplines, i.e., social statistics, seek to grasp the crowd as a structure with its intricate and partly paradoxical qualities. In recent scholarship, however, the diversification of the concept seems to have become even more complex: by shifting the focus from the “object crowd” to the “subject crowd”, descriptions of the multitude, the network, the swarm, or the assembly reflect the need to think of the crowd as an autonomous agency with emancipatory potentials.
’Gypsies’, Natural Monogamy, and Violence Full of Love
Authors: Řičář Josef
Published: February 2025

The paper examines modern knowledge about non-human primates in Czech travel narratives concerning Africa and biological journals from the late nineteenth century to the end of the interwar period. Particular attention is given to the way discourse on primates and anthropological discourse mutually influenced each other. Inspired by the intersection of human – animal studies, critical race theory, and gender studies, the paper emphasizes the anthropomorphizing character of biological discourse and popular travel narratives. At the time, presentations of primates created a specific anthropological resource and, in addition, helped to naturalize the dominant racial and gender ideologies. In the context of the Austrian–Hungarian and Czechoslovakian relative inability to obtain colonial possessions in the way western powers did, the representations of anthropomorphized non-human primates can also be interpreted as a specific field where Czech colonial fantasies about dominance were expressed.

Universities face the challenge of a lack of alumni engagement, with many losing contact after graduation. This results in difficulties in leveraging alumni potential. Insufficient communication leads alumni to feel that their relationship with the university is limited to their time as students. The low response rate to Tracer Studies, which track alumni careers and gather feedback, highlights this issue. Data from various universities indicate low response rates, primarily due to weak relationships and alumni's lack of awareness about the importance of Tracer Studies. Therefore, the development of an Alumni Relation Management system is necessary. The development of a web-based Alumni Relation system used the prototyping method. Evaluation was conducted using Heuristic Evaluation with experts, followed by system implementation through email campaigns to enhance alumni-university engagement. These steps aim to address alumni engagement issues and improve Tracer Study response rates. System testing was performed using black box testing and usability testing. The results indicated that the system functions well in both functional and non-functional aspects. Based on these findings, the system is ready for use and is expected to enhance alumni engagement and the effectiveness of Tracer Studies.

The rapid evolution of digital technology is transforming educational practices, enhancing accessibility and interactivity through innovations like augmented reality (AR) and artificial intelligence (AI). This study aims to develop the PDBI Tour application, an AR-based navigation tool integrated with speech recognition, to improve campus accessibility for new students and promote Politeknik Digital Boash Indonesia, a vocational education in Bogor Regency. A Game Development Life Cycle (GDLC) methodology was adopted, comprising initiation, pre-production, production, testing, beta, and release phases. Data were collected through interviews with promotional teams and prospective students, and prototype design was created using Figma, while Unity was used for production with AR Foundation and Whisper API. Functional testing (black box) confirmed reliable navigation features, and usability testing yielded a 65% satisfaction rate from 25 respondents representation of students in PDBI aged 18-20 years who had tried the prototype, highlighting effectiveness in usability, playability, and accessibility. These findings indicate that the PDBI Tour application prototype meets user needs and offers potential as an immersive navigation and promotional tool. This research demonstrates the GDLC approach’s efficacy in enhancing application development through iterative improvements, validating AR navigation as a powerful tool for interactive and accessible campus experiences.
