Published: December 2023

Abstract
In this article, we define evolutoids and pedaloids of frontals on timelike surfaces in Minkowski 3-space. The evolutoids of frontals on timelike surfaces are not only the generalization of evolutoids of curves in the Minkowski plane but also the generalization of caustics in Minkowski 3-space. As an application of the singularity theory, we classify the singularities of evolutoids and reveal the relationships between the singularities and geometric invariants of frontals. Furthermore, we find that there exists a close connection between the pedaloids of frontals and the pedal surfaces of evolutoids. Finally, we give some examples to demonstrate the results.

Abstract
In areas with high incidence of tuberculosis (TB), there are more infertile women who underwent in vitro fertilization (IVF) and have latent TB infection (LTBI), and thus, their potential risks should be paid enough attention. The purpose of our study aimed to analyze the relationship between LTBI and clinical pregnancy outcomes of IVF and fresh embryo transfer (IVF–FET). This was a retrospective study of 628 infertile women who had undergone IVF–FET in the Fourth Affiliated Hospital of Hebei Medical University from January 2019 to December 2021. The women experienced no clinical symptoms, negative imaging, and T-SPOT.TB-positive diagnosis of LTBI. We divided the study population into the LTBI group and the non-LTBI group. The clinical pregnancy rate in the LTBI group was significantly lower than that in the non-LTBI group (40.54% vs 49.51%, P = 0.031), and there was no significant difference in live birth rate and miscarriage rate between the two groups. Logistic regression analysis showed that LTBI was an independent risk factor for decreased clinical pregnancy rate in infertile women undergoing IVF–FET. In conclusion, LTBI affects clinical pregnancy rate of IVF–FET in infertile women, and therefore, clinicians (especially in countries with a high TB burden) need to pay attention to LTBI before IVF and embryo transfer.

Abstract
The heat transfer phenomenon associated with the lubricated surfaces offers applications in the manufacturing processes, thermal systems, industrial systems, and engineering phenomenon. It is a well-established fact that improvement in heat transfer is recently successfully claimed with the interaction of nanoparticles. Following such motivation in mind, the prime objective of current continuation is to perform the prediction of heat transfer in second-grade material subject to the lubricated surface. The lubricants are filled with non-Newtonian power law material. The varying thickness of the thin lubricating layer permits an imperfect slip surface. The second-grade fluid interfaces with the boundary condition. The modified semi-analytical tool termed as hybrid homotopy scheme is used to perform the simulations. Shooting and homotopy methods are combined in this new approach. Relevant effects of parameters on physical phenomenon are explained. The importance of influencing parameters in relation to the velocity field, temperature, and concentration profiles is investigated graphically. It is claimed that analytical computations existed for shear thinning case. It is observed that there is a noticeable drop in concentration and thermal profiles due to the variation of viscoelastic parameter. The control of free stream velocity is claimed due to the interaction of slip parameters.

Abstract

Objectives
Alzheimer’s disease (AD) is an irreversible and progressive neurogenerative disorder, which affects the learning part of brain. It mainly affects the aged population and becoming a global health issue, expecting to increase more in near future. Late diagnosis of AD worsens the situation and difficult to treat the patient. Various biosensing techniques with suitable biomarkers have been developed by researchers to diagnose the earlier stages of AD.

Methods
This research was focused to develop a highly sensitive zeolite-dual probe-modified impedance biosensor for identifying AD biomarker, Aβ Oligomer (AβO). The sensing surface was initially modified with zeolite through the chemical linker and then a dual probe of anti-AβO aptamer and anti-AβO antibody were attached to the surface of the zeolite.

Results
On these dual probe-modified surfaces, AβO was quantified to diagnose AD. Further, AβO spiked artificial CSF was identified by dual probes without any interference, indicating the selective identification of AβO. In addition, control experiments with non-immune, complementary, and control proteins failed to show the increment of responses, confirming the specific detection of AβO.

Conclusions
This zeolite-dual probe-modified biosensor helps to lower the limit of detection to 0.1 pM and diagnose AD at the earlier stages.

Abstract
This paper provides information on the significance of environmental sustainability and the potential benefits of implementing green laboratory processes. Sustainability is a broad concept that includes goals such as conservation of natural resources, energy efficiency, waste management, and reducing environmental footprints. Green laboratories strive to minimise environmental footprints by embedding sustainability principles into their everyday practices. This involves improvements in energy consumption, water usage, chemical waste reduction, and recycling, ultimately, as well as lower waste disposal costs. Implementing green laboratory approaches provides many benefits, such as a smaller environmental footprint, increased energy efficiency, water conservation, and cost savings. Moreover, a rational test ordering process can effectively contribute to reducing environmental impacts in medical laboratories. Rational test ordering provides cost-effectiveness and reduces the carbon footprint. Establishing a green and sustainable laboratory culture in medical laboratories requires a permanent organisation in where all personnel participate. Training of the hospital management teams, clinicians, and laboratory professionals is a vital point. Methodology and quality indicators should be defined by international and national laboratory associations within the framework of a green and sustainable laboratory plan, and data should be collected. In conclusion, adopting green laboratory practices reduces environmental impacts, saves costs, and accelerates innovation processes. Setting quality targets and rational test ordering practices are also essential for sustainability. Applying sustainability principles in laboratory workplaces is an important step towards protecting the environment and leaving a more liveable world for future generations.

OBJECTIVES
Early warning scores detecting clinical deterioration in pediatric inpatients have wide-ranging performance and use a limited number of clinical features. This study developed a machine learning model leveraging multiple static and dynamic clinical features from the electronic health record to predict the composite outcome of unplanned transfer to the ICU within 24 hours and inpatient mortality within 48 hours in hospitalized children.

METHODS
Using a retrospective development cohort of 17 630 encounters across 10 388 patients, 2 machine learning models (light gradient boosting machine [LGBM] and random forest) were trained on 542 features and compared with our institutional Pediatric Early Warning Score (I-PEWS).

RESULTS
The LGBM model significantly outperformed I-PEWS based on receiver operating characteristic curve (AUROC) for the composite outcome of ICU transfer or mortality for both internal validation and temporal validation cohorts (AUROC 0.785 95% confidence interval [0.780–0.791] vs 0.708 [0.701–0.715] for temporal validation) as well as lead-time before deterioration events (median 11 hours vs 3 hours; P = .004). However, LGBM performance as evaluated by precision recall curve was lesser in the temporal validation cohort with associated decreased positive predictive value (6% vs 29%) and increased number needed to evaluate (17 vs 3) compared with I-PEWS.

CONCLUSIONS
Our electronic health record based machine learning model demonstrated improved AUROC and lead-time in predicting clinical deterioration in pediatric inpatients 24 to 48 hours in advance compared with I-PEWS. Further work is needed to optimize model positive predictive value to allow for integration into clinical practice.

Objetivo: Analizar la relación entre la pobreza y las actitudes hacia las prácticas de cuidado infantil en áreas rurales y urbanas de Colombia.

Método: El presente artículo es un estudio transversal correlacional en el departamento del Atlántico, al norte de Colombia. Se indagó sobre las actitudes hacia el cuidado infantil y las condiciones de vida en 1189 cuidadores de niños en edad preescolar. Se tuvo en cuenta el índice de pobreza multidimensional y el área de procedencia de los participantes (urbana o rural).

Resultados: No se encontró una relación directa entre las actitudes hacia el cuidado infantil y el índice de pobreza multidimensional. Sin embargo, se observó que los participantes de áreas urbanas provenientes de zonas vulnerables presentaron un mayor índice de pobreza y mostraron actitudes menos positivas hacia el cuidado infantil, especialmente en el cuidado cognitivo, del sueño y de la salud. Se evidenció un efecto moderador del área sobre las actitudes de cuidado.

Conclusiones: El estudio destaca la influencia de la pobreza y la vulnerabilidad social en las actitudes de cuidado infantil, especialmente en áreas urbanas. Estos hallazgos subrayan la importancia de considerar las condiciones socioeconómicas y geográficas al abordar el cuidado infantil. Además, se resalta la necesidad de implementar estrategias específicas para promover prácticas de cuidado positivas en contextos más vulnerables, con el fin de mejorar el desarrollo de la primera infancia en Colombia

Published: December 2023

Puberty is a transitional period experienced by humans. This period is closely associated with physical, psychological, and emotional changes. Adolescents' responses to puberty can vary. We conducted a qualitative study to determine the definition of puberty and opinions and feelings about facing or experiencing puberty. Our research was conducted in one junior high school by conducting interviews in two focus group discussions. We found two major themes in this study: first is the definition of puberty, and second is the feeling about puberty. Both themes consisted of several sub-themes. The respondents stated that puberty is a maturity period characterized by significant physical, psychological, and emotional changes. The respondents also expressed that they were surprised by the changes they experienced. In addition, for them, puberty is the beginning of new obligations in their social environment. Attraction to the opposite sex makes them more careful and they must be able to control themselves. The need to share friends and role models is one of their recognitions in puberty. Other than that sex education indeed for better information. This study can be used as a reference for understanding the needs of adolescents regarding puberty so that they can better adapt and maintain sexual and reproductive health for good health and well being.

Abstract
This article discusses how the dialectic of emergency of state with the principle of legal objectives against the stipulation of Government Regulation instead of Law (PERPPU) Number 2 of 2022 on Job Creation into Law Number 6 of 2023. The research method uses a normative legal research model. The results showed that forming regulations on job creation in Indonesia is a dynamic aspect of policy formulation for the community, either pro or con. The state’s emergency is interpreted subjectively, where the President has the authority to issue PERPPU if the country is in a dangerous situation to prevent a legal vacuum. The lawful purpose of the stipulation does not only stop at the aspect of legal certainty but needs to pay attention to the principles of justice and expediency as the purpose of the nation and state.

Published: December 2023

Abstract
One of the WTO disputes that have recently been rife are disputes over technical barriers. Within the WTO itself, arrangements related to technical barriers are contained in the Agreement on Technical Barriers to Trade (TBT Agreement). Generally, disputes over technical barriers are associated with violations of the provisions of Articles 2.1 and 2.2 of the TBT. However, what constitutes a violation of the non-discrimination principle in Article 2.1 of the TBT? And what is the basis for the violation of the provisions of Article 2.2 TBT? This article will attempt to explore the elements of violations in Articles 2.1 and 2.2 of the TBT. The analysis will refer to previous disputes such as the DS381 (US-Tuna II Case), DS384 (US-COOL Case), and DS406 (US-Clove Cigarette Case). These disputes contain various landmark decisions that produce new precedents which are then later to be used as a reference on future technical barriers dispute. This article attempts to describe the interpretation and analysis of the panel and the appellate body in analyzing the elements of violations of the provisions of Articles 2.1 and 2.2 of the TBT.

Conflicting Opinions and Emotions in Students’ Responses to Feminist Resistance in the Film Photocopier
Authors: Sari Artanti Puspita 
Published: December 2023

The film Photocopier depicts how its main character, a victim of sexual harassment, exercised her feminist resistance toward hegemonic and patriarchal power in society. Studies have been conducted in the past to examine feminist resistance in this film and a few other films. Yet, none have looked closely into students' responses to feminist resistance in those films. Engaging students in responding to film contents is important because films have the potential to provoke students’ critical thinking and emotions toward various issues in society, such as issues related to the victimization of women. To address the gap in research, this study aimed to examine how students express their opinions and emotions toward the female main character’s resistance in the film Photocopier. It also aimed to analyze how those opinions and emotions may influence students’ potential actions when faced with sexual harassment issues in real life. Using an audience response method, data were collected through observations that included film viewing, a classroom discussion, and an open-ended questionnaire. The study involved eleven female and two male graduate students in a literature teaching and appreciation course. The results showed that each student experienced conflicting opinions and emotions with regard to the main character’s resistance. After watching the film, students felt motivated and inspired to advocate for victims of sexual harassment in real life. The researcher argues that conflicting opinions and emotions were inevitable consequences of students’ critical thinking and emotional processes while responding to the film. The negative opinions and emotions that even led to victim blaming did not hinder them from supporting the main character’s efforts to obtain justice. Furthermore, the researcher argues for the necessity of developing audience responses to films as a powerful strategy in critical literature pedagogy.

Published: December 2023

Abstract
In the paper results of numerical analysis of KCl and KF contamination particles present in liquid aluminium assimilation to the slag are presented. Authors analyzed contamination particle movement in the slag model, which base on buoyant, capillary, viscosity, Newton and repulsion forces, interfacial tensions at the interface of phases and surface energy during the particle movement through phases boundary. On the base of the mathematical model computer program was written to make simulations under different conditions. In the paper results of particle position in the slag for different particle radiuses: 1, 5, 10, 20 µm, and constant slag viscosity including velocity evolution are presented. Another approach was used to indicate influence of slag viscosity on particle and slag penetration depth. During computations selected slag viscosities of 0.0012, 0.0015, 0.0018 [kg / m·s] were taken into account. Different comparisons were made for chosen particle sizes. Each examination takes into account impact of contamination particle type. Results clearly show that for larger particles slag penetration depth is greater and viscosity of the slag has an impact on velocity evolution during assimilation process.

Abstract
Typha domingensis (Typhaceae) has been reported as a heavy metal (HV) hyperaccumulator in several studies. The purpose of the current study was to look into the seasonal variations in the accumulation potential of T. domingensis (TD) for HV in degraded wetlands in Greater Cairo, Egypt. Sampling of recent wild plants from the TD's subterranean and surface components was gathered from different contaminated sites distributed in the canal of Ismailia and Nahia drain, as well as from the River Nile as an uncontaminated site (control). The findings showed that pollution had a negative effect on the chemical characteristics of sediment and water. Seasonal fluctuations in the growth characteristics that are significant, except for the leaf area of the TD, were recognized. The subterranean plant components stored higher amounts of HV than that of aboveground shoots. Mn concentration (413.2 mg kg-1) was greater in the roots of autumnal plants, whereas their shoots recorded the highest Pb (225.8 mg kg-1). Al, Cd, Cu, Fe, Ni, and Zn concentrations were highest in summer plant roots (1499.9, 74.8,1356.1, 3948.8, 403.8 and 1294.2 mg kg-1, respectively). Chlorophyll b and carotenoid levels both decreased significantly. Chlorophyll b decreased by 32%, while carotenoid content decreased by 28% in contrast to the control samples. The factor of metal bioaccumulation (BF) values, were high in TD plants growing in a contaminated Ismailia canal, but factors for translocation (TF) values for all measured elements were lower than one, except for Pb. As a result, summer is the best time of year for TD to sequester high HV concentrations. The authors recommended that TD may be employed to mitigate HVs pollution in wetlands.
