Authors: Iskandar Ainaa Idayu , Romaiha Noor Rafhati , Jahya Arnida 
Published: December 2024

The virtual mode of the classroom that changes from the traditional education model poses challenges among the educators especially the inability to cope with the adaption of educational technologies. Online literacy is the basic skill to exercise an outstanding performance during changing environments. However, the conceptualization of adaptive performance seeks further exploration mainly because the past studies focus on the specific context. This study aims to present the validity and reliability of the adaptive performance construct related to online teaching platforms among Malaysian public university lecturers. The questionnaire was designed using Google Form and the adopted questionnaire was emailed to lecturers of Malaysian Research Universities (henceforth, RUs) via their institution’s email address. The data were then analyzed using the SmartPLS software through the measurement model analysis. The analysis involved a second-order approach where the outer loading values, the convergent validity of Average Variance Extracted (henceforth, AVE), and reliability analysis of the adaptive performance construct. The findings suggest that the validity and reliability of the construct were established for the context of the study. The Cronbach Alpha and composite reliability values scored above the threshold values. This study confirmed the adaptive performance instrument among the lecturers in Malaysia and can provide insight for future research. The limitation includes the sample of the study that was rather homogenous which it only focused on lecturers from Malaysian RUs.

Published: December 2024

The study aims to assess the perception of the Muslim community towards the general management of Qurban by mosques in Malaysia and to determine whether the Qurban ritual complies with the Shariah principles. Questionnaires were distributed to around 466 Muslims in the Central and Southern regions of Malaysia. Findings revealed that the Muslim community perceived that the Qurban ritual was managed efficiently by the mosques and that the Qurban process complied with the Shariah requirements. Nevertheless, the satisfaction rate of the Muslim community was slightly lower on certain aspects of the management and compliance with the Shariah requirements. The study proposes that the mosques should take the initiative to enhance the internal control system in managing the Qurban by disseminating Qurban distribution reports to the public as well as combatting the risk of misappropriation of Qurban meat.

Published: December 2024

Providing excellent public transportation in response to the passenger’s complaints and recommendations results in long-term improvements to the service. This study investigates public perceptions of the MRT and LRT rail transportation services within the Klang Valley Integrated Transit System, operated by Rapid KL, through sentiment analysis in X. With 4.4 million users in Malaysia as of January 2022, X (previously Twitter) media social serves as a significant platform for public discourse. However, analyzing these perceptions poses challenges due to the limited platforms for analysis, and seeking from X is even more challenging due to the unstructured and noisy nature of the tweets. Therefore, this study aims to develop a sentiment analysis model that organizes tweets into structured data, utilizing machine learning techniques for sentiment classification into positive, neutral, and negative categories. Following the model implementation, the data are collected, translated, cleaned, labeled, analyzed, and classified using a Support Vector Machine before being deployed in a web system for ease of access. Analysis results revealed that user sentiment is predominantly neutral, with a significant focus on MRT services and topic finding related to scheduling. The model scored good accuracy 80% without a kernel and 84% with a Linear kernel, with evaluation metrics demonstrating strong performance on all three sentiment categories. Future enhancements will include label refining and applying more hyperparameter tuning to improve analysis accuracy.
European Firms’ Delisting Around Major Regulatory Shocks: The Cost-Benefit Tradeoff of the Financial Services Action Plan
Authors: Gutierrez Elizabeth , Rykaczewski Maria , Vulcheva Maria I. 
Published: December 2024

ABSTRACT
Between 1999 and 2005, the EU adopted the Financial Services Action Plan (FSAP) to reshape its financial markets. In this paper, we examine the firm-level effect of this major regulatory shock. In pre/post-2005 analyses, we compare the probabilities of companies voluntarily or involuntarily delisting in seven European economies that strongly commit to implementing regulations and seven economies that apply regulations more leniently. Our findings indicate an increased probability of delisting after 2005, primarily due to involuntary delistings in economies that implement regulations strictly. Furthermore, we examine a core element of the FSAP, the International Financial Reporting Standards (IFRS) mandate, which aimed to improve public firms’ reporting and disclosure quality. IFRS continued to undergo rapid changes after 2005, and we document an incremental association between delisting and the post-2005 changes. Our results highlight the firm-level consequences of the FSAP across jurisdictions with varying institutional environments.

Iodinated contrast dye–diluent combination exhibits longer time to full dye saturation compared to lidocaine, bupivacaine, and water in porcine cadaveric nervous tissue
Authors: Albano Victoria , Hon Stephanie , Parry Stephen , Garcia Cristina de Miguel 
Published: December 2024

Abstract

OBJECTIVE
Dye-diluent combinations have different nerve-staining behavior, making locoregional cadaveric dye study findings difficult to compare. The objective of this study was to quantify the effect of 4 diluents on nerve color saturation when used in combination with commercial food dye.

METHODS
48 unpreserved brachial plexus nerves were randomized into 4 diluent groups. Lidocaine, bupivacaine, iodinated contrast, and sterile water were combined with commercial food dye (10:1), and prosected nerves were immersed in one of these groups for 1, 15, 30, or 60 minutes. Images at baseline and at each timepoint were processed using ImageJ. Color saturation was divided into quartiles (dark, medium dark, medium light, or light). The percentage of nerve area stained in each quartile was compared using a 2-way ANOVA and post hoc Tukey test.

RESULTS
At 1 minute, water and bupivacaine had a higher percentage of area of dark saturation compared to contrast. At 15 and 30 minutes, dark and medium-dark saturation percentages of area were also larger in lidocaine, bupivacaine, and water compared to contrast. There were no differences in saturation percentages of areas between groups at 60 minutes. Within groups, all diluents had darker percentages of area saturation at 15, 30, and 60 minutes compared to minute 1.

CONCLUSIONS
In porcine nerves, the staining profiles of 2% lidocaine, 0.5% bupivacaine, and sterile water combined withcommercial food dye appear similar and may be used interchangeably after 15 minutes of exposure. When using iodinated contrast, exposures over 60 minutes yield comparable results to other diluents.

CLINICAL RELEVANCE
Diluents contribute to heterogeneous nerve-staining behavior and should be considered when comparing study outcomes. If contrast is used as the diluent in cadaveric studies with postoperative imaging, researchers should be aware of the significant delay to reach a saturation level comparable to other diluent combinations.
Pneumonitis with amivantamab in squamous cell lung cancer with EGFR exon 20 insertion mutation: a case report
Authors: Cruz Margarida Melo , Silva Ana Filipa , Raimundo Sara , Gomes Teresa 
Published: December 2024

Abstract

Background
Amivantamab is a human antibody targeting epidermal growth factor receptor (EGFR) and c-MET. It is approved in patients with advanced non-small cell lung cancer (NSCLC) with EGFR exon 20 insertion after progression with platinum-based chemotherapy. The most frequent adverse effects (AEs) are rash, infusion-related reactions, paronychia, and peripheral edema. Pneumonitis is a rare side effect, and there is no evidence about the possibility of reintroducing amivantamab after pulmonary toxicity.

Clinical case
A 56-year-old male was diagnosed with squamous cell lung cancer in 2021, with brain metastasis at diagnosis. The brain lesion was resected, and histopathologic assessment revealed metastasis from squamous cell lung cancer, and an exon 20 insertion mutation was identified. Chemotherapy with immunotherapy (carboplatin + paclitaxel + pembrolizumab) was initiated in October 2021, and progression was observed after three maintenance cycles. Amivantamab was started in May 2022, and partial response was observed after 2 months of treatment. In September 2022, the patient complained of dyspnea on exertion and dry cough. Computed tomography (CT) scan showed scattered ground-glass opacities. A pneumonitis grade 2 CTCAE was assumed, and corticosteroid therapy was started, with improvement in both symptoms and imaging abnormalities. After discussion with a multidisciplinary team, it was decided to restart treatment with amivantamab in January 2023 and there is no evidence of pulmonary toxicity to this date.

Conclusion
Amivantamab-related pneumonitis is a rare side effect and usually predicts drug discontinuation. In this clinical case, it was possible to reintroduce the drug without reoccurrence of the toxicity successfully. This possibility of reintroducing treatment after non-life-threatening toxicity occurs can be of great importance as therapeutic options for these patients are limited.
Understanding Geotechnical Embankment Washout Due to Overtopping: Insights From Physical Tests
Authors: Urbaniak Mikołaj , Zamiar Krzysztof , Kostecki Stanisław 
Published: December 2024

Abstract
Understanding the erosion process of an earth dam and flood embankment composed of noncohesive, homogeneous soils due to overflow is crucial for determining the quantity and rate of water release. This is necessary to assess the consequences of a failure, analyze the risk, and develop appropriate crisis management procedures. Despite numerous studies in this area, the process of breach evolution is not fully explored. The article presents the results of physical experiments carried out in the field laboratory of the Wrocław University of Science and Technology for a dam with a height of 0.50 m that closes a reservoir with a capacity of 14.4 m3, whose width is significantly greater than the final width of the breach. The scenario analyzed assumes that water overflows the embankment crest, as it is the most common cause of embankment failure based on dam disaster databases. At the same time, the amount of water accumulated in the reservoir is the largest possible for this scenario, suggesting that such a catastrophe may have the most severe consequences. Based on the results obtained from three experiments, four repeatable phases of erosion evolution were identified and described: (I) the initiation phase, (II) the vertical erosion phase, (III) the lateral erosion phase, divided into two cycles, and (IV) the reservoir emptying phase without further propagation of the breach. The outflow rate of the water from the reservoir was also analyzed, allowing the determination of the outflow hydrograph for each test. Hydrographs showed differences between individual experiments; however, the average erosion rate was similar for all tests. Furthermore, the final width of the breach created each time was between 2.2 and 2.5 H (where H is the height of the embankment) and the volume of eroded soil ranged from 0.52 to 0.59 m3. The article also highlights the methodology to calculate the water outflow hydrograph.
Maquiagem Infantil: aspectos regulatórios, controle de qualidade, padrões de uso e segurança.

Published: December 2024

O Brasil é um dos maiores mercados mundiais de cosméticos infantis, e há um grande interesse das crianças por produtos de beleza, o que chama a atenção de pais e autoridades sanitárias quanto à sua segurança. Desde 2018 as maquiagens infantis são isentas de registro no Brasil, e embora sejam normalmente associadas aos adultos, também são amplamente comercializadas para crianças, por isso podem ser vistas como brinquedos. Neste caso, o termo toy makeup é utilizado. As crianças têm a pele mais permeável, fina e imatura, o que as torna mais vulneráveis, sendo o uso precoce prejudicial à sua saúde, aumentando a incidência de alergias, irritações cutâneas e intoxicações por ingestão. O presente trabalho realiza uma revisão da literatura acerca das maquiagens infantis, ressaltando os aspectos regulatórios, a avaliação da segurança, os padrões de uso e seu controle de qualidade. Foram utilizadas as bases de dados Science Direct, Pubmed, Google Scholar e Springer, e ao total, foram selecionadas 49 referências. As crianças devem usar somente produtos infantis, e a maquiagem que vem com brinquedos não deve ser aplicada na pele. Os componentes da formulação que mais desencadeiam reações alérgicas são os conservantes, fragrâncias e metais, e o controle de qualidade relacionado à presença de metais em maquiagens é uma área ativa de pesquisa e atividade regulatória. Em média, 62% das crianças até 12 anos já utilizou maquiagem e o início do uso foi aos 4 anos de idade, sendo o principal motivo (75%) a vontade da própria criança. O produto mais utilizado é o esmalte (52%), seguido do batom (45%), e o menos utilizado é o delineador (11%). Existem legislações brasileiras atuais acerca das maquiagens infantis, e há uma diferenciação não somente no conceito de “maquiagem” e “brinquedo”, mas também nas exigências regulamentares a que estão sujeitos. Palavras-chaves: Toy makeup; Maquiagem infantil; Segurança; Regulação.
Association Between Pediatric International Knee Documentation Committee Score and Sagittal Knee Biomechanical Testing Following Anterior Cruciate Ligament Reconstruction
Authors: Lin Eric H. , Katzel Mia , Liang Adriana , Wren Tishya 
Published: December 2024

OBJECTIVE: The purpose of this study was to compare the Pediatric International Knee Documentation Committee (Pedi-IKDC) scores with sagittal knee kinematics and kinetics during the vertical drop jump test in pediatric athletes who had undergone primary unilateral anterior cruciate ligament reconstruction (ACLR) and determine if the two measures captured overlapping aspects of knee recovery. DESIGN: This is a retrospective cohort study. METHOD: Seventy pediatric athletes who recently underwent ACLR completed biomechanical testing and the Pedi-IKDC survey. Limb symmetry for peak knee flexion angle (PKF), peak external knee flexion moment (PEKFM), and integral of power absorption (IPA) were evaluated and compared to Pedi-IKDC score using multivariate linear regressions controlling for time since surgery. Inter-knee symmetry was calculated using a Limb Symmetry Index (LSI) by dividing the scores of the injured knee by the scores of the uninjured knee and multiplying by 100. RESULTS: There was a statistically significant positive relationship between Pedi-IKDC and LSI in PKF ( R2 = .163, p =.001), PEKFM ( R2 = .067, p = 0.033), and IPA ( R2 = .087, p = .014), indicating that higher Pedi-IKDC scores were associated with greater biomechanical symmetry when controlled for time. There were weak and significant positive relationships between time since surgery and PEKFM ( R2 = .172, p < .001) and IPA ( R2 = .255, p < .001), indicating improved biomechanical testing the further along from surgery, but there was no statistical significance between time since surgery and Pedi-IKDC or PKF. CONCLUSIONS: Pedi-IKDC and drop jump biomechanics were weakly related but mainly captured different aspects of recovery after ACLR. They can be considered as complementary tools when evaluating patients post-ACLR. JOSPT Open 2025;3(2): 1-7. Epub 4 December 2024. doi:10.2519/josptopen.2024.0073

В работе приведены результаты расчетных исследований радиационной безопасности при обращении со свежим топливом, содержащим предельное по техническим условиям для таблеток топлива реактора РБМК-1000 количество 232U, 234U и 236U. Показано, что при обращении со свежим топливом за счет повышенного содержа­ния 232U возрастают мощности доз от тепловыделяющей сборки и транспортного упаковочного комплекта и, как следствие, дозовые нагрузки на персонал. При ограничении времени между получением обогащенного гексафторида урана и загрузкой топлива в реактор дозовые нагрузки на персонал не превышают нормативных пределов.
The article presents the results of radiation safety calculation studies of handling with fresh fuel with maximum permissible concentrations of 232U, 234U and 236U isotopes in the fuel pellets of RBMK-1000 reactor. It is shown that during handling with this fuel composition the dose rates from fuel assembly and transport and packing set are increased due to the increased content of 232U. As a consequence, the dose rates to nuclear plant personnel are also increased. If the time between enriched uranium hexafluoride producing and reactor fuel loading is limited, dose rates to nuclear plant personnel do not exceed regulatory limits.

Правильная классификация систем и элементов технических устройств играет очень важную роль при их проектировании, изготовлении и эксплуатации, позволяет предъявлять к различным системам и элементам дифференцированные требования, обеспечивая их функционирование наилучшим образом и достижение целей, для которых эти технические устройства были созданы. При формировании требований по безопасности атомных станций в Советском Союзе в конце 60-х – начале 70-х гг. возник вопрос о классификации систем и элементов, а вместе с ним и противоречия с существовавшей тогда классификацией МАГАТЭ.
The correct classification of systems and elements of technical devices plays very important role at their design, production and operation, allows making the differentiated requirements to various systems and elements, providing their functioning in the best way and achievement of the objectives for which technical devices were created. When forming requirements for safety of nuclear power plants in the Soviet Union in the late 60th — the beginning of the 70th there was a question of classification of systems and the elements, and contradictions together with it with the classification of IAEA existing then.
