Implemental delay as a mediator of the relationship between depression, anxiety, stress and school burnout
Authors: Markiewicz Katarzyna , Kaczmarek Bożydar L. J. 
Published: December 2024

Introduction
Research following the COVID-19 pandemic points to many problems related to adolescents’ mental condition, their coping with the organization of daily life and the implementation of school duties, which can lead to school burnout. It includes absenteeism, decreased motivation and academic performance, and a cynical attitude toward peers and teachers. A significant way to protect adolescents’ mental health may be by teaching them to complete their daily duties. Still, an obstacle is the observable post-pandemic, increasing tendency to procrastinate, which can exacerbate the effects of school burnout. The study aimed to establish the impact of depression, anxiety and stress on school burnout mediated by procrastination, understood as implemental procrastination.

Method
Three questionnaires were used: Depression, Anxiety and Stress Scale, Implemental Delay Scale, and School burnout scale. The study comprised 344 students (57,6% females) from Polish secondary schools (high schools and technical schools), aged 14–20 years (M = 16.69; SD = 1.74). The analysis of relationships between variables studied was performed with the mediation model.

Results
Analyses confirmed the mediating effect of implemental delay on the relationship between depression, stress and school burnout. Unexpectedly, it turned out that the burnout resulting from parental pressure significantly weakened the value of the mediator (implemental delay). In contrast, the value of the predictors (depression and stress) increased. Anxiety was found to be a nonsignificant predictor of school burnout.

Conclusion
The data show that stress, depression and procrastination influence school burnout, which depends mainly on the dimension of burnout. Awareness of these relationships can support the creation of specialized prevention programs, allowing students to overcome their problems. At the same time, parents and teachers may help them understand the nature of observed disorders, which has little to do with laziness often attributed to young people.

The Hospital Anxiety and Depression Scale (HADS) is commonly used to detect depressive or anxious states, but its 14-item questionnaire is time-consuming. Visual analog scales (VAS) are easy to use and quick to implement. Although the VAS has been validated to assess pain and occupational stress, VAS scores for anxiety and mood have never been evaluated in the workplace. We aimed to validate the use of visual analog scales (VAS) for anxiety and mood compared to HADS in workers. A HADS self-reported questionnaire associated with VAS assessing perceived anxiety and mood on a horizontal line of 100 mm was administered to 182 workers, with a second test (retest) proposed one week later. Sociodemographic, characteristics of work, sleep, well-being, and stress were also assessed. VAS anxiety and mood correlated with the HADS sub-scores (0.70 and 0.65, respectively). The test-retest reliability was good. Optimal VAS cut-offs were ≥ 60/100 for anxiety and ≤ 60/100 for mood, to define at-risk patients. The VAS is quick to perform, easy to use, and reliable for screening depression and anxiety in occupational medicine. We recommend validated questionnaires for at-risk patients.

Authors: Saetang Mantana , Kunapaisal Thitikan , Wasinwong Wirat , Boonthum Parin , Sriyanaluk Bussarin , Nuanjun Kanjana 
Published: December 2024

Background
To highlight the risk assessment tool associated with postoperative cardiopulmonary complications of Clavien–Dindo (CD) ≥ II in elderly patients who underwent lung cancer surgery.

Methods
In patients ≥ 60 years admitted during 2020–2023 and having undergone lung cancer surgery, postoperative cardiopulmonary complications were examined using the CD classification as groups (CD grade I versus ≥ II), and the risk factors were analyzed using logistic regression and receiver operating characteristic (ROC) curves.

Results
Of the 239 elderly patients, 29.3% had postoperative complications (CD ≥ II). Subgroup analysis revealed that patients aged ≥70 years had a higher rate of postoperative complications compared to those aged 60–69 years, however, this relationship was not statistically significant in the multivariable model (OR: 2.03, 95% CI: 0.95–4.36, p = 0.068). The CD grade ≥ II group had longer surgical time (p = 0.002), greater postoperative pulmonary complications (p < 0.001), and longer length of hospital stay (p < 0.001); CD grade ≥ II was more likely in patients with older age (odds ratio [OR]: 1.08, 95% confidence interval [CI]: 1.02–1.15, p = 0.011), COPD (OR: 4.41, 95% CI: 1.55–13.44, p = 0.005) and smoking history (OR: 2.85, 95% CI: 1.12–7.24, p = 0.028), having undergone pneumonectomy (OR: 14.89, 95% CI: 1.71–334.9, p = 0.045), and who converted to open thoracotomy (OR: 16.33, 95% CI: 2.13–169.71, p = 0.007). The area under the ROC curve was 0.81.

Conclusions
Older age (≥70 years) is associated with higher rates of postoperative complications (CD classification ≥ II) but is not an independent predictor when adjusting for other factors. Comorbidities such as COPD and surgical factors, including pneumonectomy and conversion to thoracotomy, are significant contributors. These findings emphasize the need for comprehensive, multifactorial risk assessments to guide perioperative management and improve outcomes in elderly lung cancer patients.

We hardly need to use our ears: Video, audio and the shaping of the podcast medium in the 2020s
Authors: Berry Richard 
Published: December 2024

In 1979, the British pop band The Buggles released ‘Video Killed the Radio Star’, generating a provocation used to explain change (where x killed y). Two years later, the song’s video was used to launch MTV, marking a change in how audiences consumed music. It is not the title that is of interest here, but a line in the track that suggests in the age of video, that we no longer need to use our ears.
Although the open standard of podcasting has meant that video and audio could coexist, podcasting has been primarily an auditory medium. However, in 2024, several leading podcasts on Spotify now play as easily as video as audio. This article discusses this evolution, arguing that this shift not only reflects the actors that shape podcasting but also poses questions for how we might define podcasting in its third decade. Is podcasting still an aural medium?

INTRODUCTION:
Coins are the most commonly ingested foreign bodies. When they get stuck in the distal esophagus, there is no general agreement about the timing of their removal because some of them may spontaneously migrate into the stomach, no longer requiring removal. We aimed at evaluating the gastric spontaneous passage of esophageal-retained coins, as well as complications.

METHODS:
Children admitted for coin ingestion were enrolled.

RESULTS:
Eight hundred seven children were enrolled. Among the medium-distal esophageal retained coins, we reported a spontaneous gastric dislocation in 65%, with no further need for endoscopy.

DISCUSSION:
When coins are trapped in the middle/lower esophagus, we suggest withholding the procedure for at least 6–12 hours, especially for older children, because 2/3 pass spontaneously, not requiring endoscopic removal.
Desigualdades culturales en el ingreso a la universidad. Un estudio de caso en psicología de la Universidad de Congreso
Authors: Gutiérrez Leticia 
Published: December 2024

El artículo examina las desigualdades de capital cultural presentes entre estudiantes de primer año de Psicología en la Universidad de Congreso. La investigación se basa en una práctica situada y forma parte del Trabajo Integrador Final de la Especialización en Docencia Universitaria de la Universidad Nacional de San Juan (UNSJ). El estudio revela que las desigualdades de capital cultural con el que los estudiantes ingresan a la institución marcan desde el inicio el proceso de aprendizaje, generando dificultades en la comprensión de los contenidos teóricos e implementación del programa académico.
La investigación destaca la necesidad de adaptar las prácticas pedagógicas y el contenido curricular para abordar la diversidad cultural del estudiantado. La consideración de la heterogeneidad de capital cultural de los estudiantes es crucial para reformular las metodologías de enseñanza desde el punto de partida de las trayectorias y promover la integración efectiva de los estudiantes del primer año de Psicología al ámbito académico, con el objetivo de aminorar las brechas de la desigualdad. Desde este posicionamiento se desprende una propuesta de intervención pedagógica que se encuentra en fase de revisión y análisis por parte del Equipo de Gestión y el Servicio de Orientación al Estudiante (SOE) de la misma Universidad
Exploring Journalism Convergence: A Qualitative Study of Media Group Network and Mahaka Media
Authors: Iskandar Dudi , Suryawati Indah , Liliyana  
Published: December 2024

The development and practice of journalism are mainly determined by the availability of information and communication technology. Internet-based technology has transformed all lines of journalism. Journalism convergence is not only a trend, but also a necessity in the contemporary media industry. There are three types of journalism convergence, namely newsroom, newsgathering, and content. In newsroom convergence, journalists from different platforms work together in one news production room and carry out their tasks in accordance with their media. Newsgathering convergence requires journalists to multitask, while content convergence or news content means that news is displayed in the form of multimedia content that combines texts, images, audio and others. This study aims to describe and analyze the practice of journalism convergence in Media Group Network and Mahaka Media. Using a qualitative approach, the researchers conduct observation, interview, and literature review as data collection techniques. This study finds that Media Group Network and Mahaka Media have already applied these three journalism convergence models (newsroom, newsgathering, and content). Media Group Network and Mahaka Media have been continuously and consistently applying those three aspects of journalism convergence. However, there are some differences in the journalism convergence process in Media Group Network and Mahaka Media, namely the code of ethics and training for journalists. Another difference is that Mahaka Media provides print on demand for its readers, while Media Group Network has broad coverage on journalism convergence through free to air television, Metro TV

Published: December 2024

Digital literacy is one of the essential skills for students in this digital age to improve their academic performance. Digital media can be used to support learning in daily school life, so both of teachers and students must be competence in the digital world. Even mobile/digital games can be used as one of the learning tools. The Ministry of Communication and Information Technology and the Ministry of Religious Affairs have joined hands to improve the digital literacy of students, especially in madrasas. However, there are no previous studies that provide us with the digital literacy of madrasa students. The aims of this study are to find out and analyze the digital literacy index of madrasa students and also their engagement with digital media. The research was conducted in MTsN in Semarang using an offline survey and the result is analysed using descriptive quantitative method. The result shows that their digital literacy is at high/good level. Students are involved in the digital world because their daily activities can’t be separated from technology and digital media. The result reflects that today’s students are considered as digital native generation whose their life development is highly influenced by digital world. In this case, knowing the digital literacy index becomes an urgent and fundamental matter
Why is the modified wedge-opening-loaded test inadequate for characterizing gaseous hydrogen embrittlement in pipeline steels? A review
Authors: Kappes Mariano A. , Palmerio Diego , Guerrina Jorge , Pérez Teresa E. 
Published: December 2024

Abstract
International hydrogen pipeline code ASME B31.12 requires the measurement of hydrogen affected fracture toughness using constant load or displacement tests standardized in ASTM E1681. The modified wedge-opening-loaded (WOL) specimen is loaded with a bolt that sets a constant crack mouth opening displacement and the initial stress intensity factor (KIapp). In this review paper, the sizing restrictions imposed by the testing procedures are analyzed considering the strength, wall thickness, diameter and toughness of existing and commercially available pipelines. The conclusion is that specimens with the standard geometry for constant displacement test in ASTM E1681 cannot be extracted from most used pipelines. The equations proposed in standards to calculate KIapp as a function of crack mouth opening displacement cannot be applied and particular expressions must be calculated case by case. Furthermore, loading the specimen to the required KIapp results in exceedingly large normal stresses in the bolt, increasing the risk of fracture of the bolt during loading of the specimen. Additionally, literature results of pipeline stees tested with the constant displacement in gaseous hydrogen are discussed and their significance is analyzed considering the material performance measured under rising displacement tests in gaseous hydrogen.

Abstract

Objectives
Diagnostic errors frequently represent significant adverse events that can occur in any medical setting, particularly in rushed handovers and constrained timing. Cases that result in emergency hospitalization at the time of the initial outpatient visit are more likely to have complex or serious patient conditions and more detrimental diagnostic errors. Our study investigated diagnostic errors in these under reported situations.

Methods
We conducted a retrospective study using electronic medical record data on patients who were directly admitted to a newly established outpatient clinic at a single university hospital in Japan. Diagnostic errors were assessed independently by two physicians using the Revised Safer Dx instrument. We analyzed patient demographics, symptoms, referrals, and resident doctor (postgraduate-year-1) involvement using logistic regression to compare groups with and without diagnostic error. Additionally, we employed the Diagnostic Error Evaluation and Research (DEER) taxonomy and Generic Diagnostic Pitfalls (GDP) to examine the factors associated with diagnostic errors.

Results
The study included 321 patients, with diagnostic errors identified in 39 cases (12.1 %). Factors contributing to diagnostic errors included the involvement of young residents, male patients, the number of symptoms, and atypical presentation. The most common causes of diagnostic errors were “too much weight given to competing/coexisting diagnosis” as indicated by DEER and “atypical presentation” by GDP.

Conclusions
The frequency of diagnostic errors in this study was higher than those in previous studies of new outpatient visits, underscoring the imperative for heightened scrutiny in cases involving medical residents especially when patients present with multiple or atypical symptoms. This vigilance is crucial to mitigating the risk of diagnostic inaccuracies in these settings. Cases that result in emergency hospitalization at the time of the initial outpatient visit are more likely to have complex or serious patient conditions and more detrimental diagnostic errors.
Theoretical – experimental investigation of performance enhancement of a PV system using evaporative cooling

Published: December 2024

Abstract
Evaporative cooling technique is considered one of the effective methods for improving efficiency and power generation of a photovoltaic (PV) module by reducing the operating temperature of its surface. In this paper a theoretical study of heat transfer through a PV module was conducted to investigate how the calculated cell temperature and module efficiency are influenced by the ambient temperature, solar irradiation, and water flow rate, which affect the heating and cooling rates of the module surface. Experimental investigation was done to confirm the theoretical findings concerning the decrease of cell temperature and hence the increase of module efficiency with the increase of either the air flow on module cooling by using sprinkler for water misting or the mass flow of water on module cooling by using nozzles for making a water film over the module surface. The experimental results show a reduction of 26.94 % in cell temperature on using sprinkler against 28.32 % for nozzles with continuous cooling and 24.14 % using sprinkler against 26.75 % for nozzles with intermittent cooling. Experimental results show that evaporative cooling on using sprinkler and nozzles methods increase the electrical efficiency from 13.04 % without cooling to 14.5 % and 14.75 with continuous cooling against increase of the electrical efficiency to 14.29 and 14.7 with intermittent cooling. The maximum electrical efficiency in the datasheet at standard condition records 15.4 %. This means that the evaporative cooling over the PV module strongly improves the system performance to approach its efficiency at standard test condition STC. There is no significant difference between continuous and intermittent cooling in reducing the cell temperature and thus increasing efficiency. Moreover, intermittent cooling reduces the amount of water used for cooling.
A review on extended special and general theory of relativity for superluminal particles and their cosmological applications

Published: December 2024

Abstract
In the context of superluminal physics, this article explores the latest advancements including the primary theoretical developments in special and general theory of relativity (STR & GTR). We have reviewed the significant strides made so far and addressed the difficulties encountered with purported interpretation. The proposed or derived transformation factors for superluminal particles can be categorized into two categories, i.e., imaginary and real transformation factors. The transformation relations between the two classes of frames have been scrutinized using the metric expressions. The velocity addition and transformation relations of mass, momentum, and energy between the frames for superluminal particles have also been analyzed. The analyses using Klein–Gordon equation, which is the relativistic energy-momentum equation, for tachyons have been performed. In brane–antibrane system, universality of tachyon potential via tachyon condensation was articulated. The unstable brane system, by virtue of tachyon condensation, promotes the cosmological evidence. In advancing the pace of development of cosmological research, superluminal physics is one of the most astonishing fields. Approaching toward GTR for cosmological application, tachyons have been scrutinized in Schwarzschild, Kerr–Newman, and FLRW metric spaces. Tachyons in Friedman universe correspond to different applications, like measurements of Hubble’s constant, theory of big-bang, expansion of universe. Some of the experimental evidences provided by GRS 1915+105, SN 1987A, GRB 030329, GW 170817, etc., for the existence of tachyons have also been analyzed. Einstein’s postulate for the constancy of the speed of light has been commented on for the highest approachable speed observed by the particular observer.

Authors: Braz Martins Lara 
Published: December 2024

O artigo intitulado “Perfil da violência sexual contra mulheres no Distrito Federal”, escrito por Gomes et al. (2024), oferece uma contribuição significativa para o debate sobre a violência sexual. O estudo realizado pelos autores tem como objetivo traçar o perfil da violência sexual em mulheres no Distrito Federal. Para isso, foram examinados 3392 laudos do SICOLA (Sistema de Controle de Laudos), do Instituto de Medicina Legal, referindo-se aos anos de 2015 a 2017. A metodologia de pesquisa escolhida por eles foi a quantitativa, considerada significativa para este tipo de produção acadêmica, pois constam análises médicas e resultados através de denúncias e investigações, oferecendo dados abrangentes e detalhados em relação à violência sexual na região. As tabelas usadas para apresentar os dados da pesquisa são de fácil interpretação, o que é ótimo para o entendimento de como se desenvolveram os casos de violência sexual contra as mulheres no Distrito Federal. O estudo é fundamental, pois fornece dados que contribuem para a construção de políticas públicas no Distrito Federal eficientes, visto que há informações precisas e focadas no perfil regional, possibilitando traçar planos locais. Justificando o parágrafo anterior, alguns Estados estão desenvolvendo políticas públicas voltadas para a proteção das mulheres contra a violência sexual. Por exemplo, no Estado de Minas Gerais, a ALMG (Assembleia Legislativa de Minas Gerais) promoveu 3 meses de discussão com membros da delegacia da Polícia Civil do Estado, secretário dos Direitos Humanos, com o objetivo de criar medidas para construção do Plano Decenal de Políticas para Mulheres, que estabelece prioridades até 2029. De forma geral, os conteúdos são de fácil entendimento e os autores tiveram a preocupação de explicar todos os detalhes de como se caracterizam as violências sexuais contra as mulheres, assim, incentivando outros profissionais a fazerem as mesmas pesquisas em seus Estados e regiões.
