Published: December 2024

Abstract
The European Union’s Green Deal agenda emphasises the major importance of cleaner and more environmentally friendly energy sources for further economic development. Hydrogen is one of the potential renewable fuels that can replace fossil fuels in a variety of economic applications. The green hydrogen production across Europe is a key factor in achieving this goal. The aim of the study is to determine the influence of the connection between the availability of renewable energy sources, innovation, and economic development patterns on hydrogen production advancement. The research provides a comprehensive correlation analysis between the number of green hydrogen production sites and their capacity with statistical indicators describing economic growth, population, innovation, and particular economic characteristics within a particular EU Member State. The statistical data of this research outline the period from 2021 until the beginning of 2024. The results of the study suggest that nine of the 23 indicators examined – population size, gross domestic product, investment in research and development, total manufacturing value, overall industry value, total electricity produced, renewables in electricity production, solar power, and wind power in electricity production – have a strong or very strong positive correlation with hydrogen production. Furthermore, the analyses revealed that countries with large populations and high GDP volumes are more likely to develop hydrogen production in existing market circumstances.

Published: December 2024

Many operators are introduced for the approximation of real functions, but little for the approximation of complex functions. These studies are for analytic functions.
In this article, we define a new type of Szasz-Mirakjan operator. Then we estimate the degree of approximation using this modified complex Szasz-Mirakjan operators to integrable functions on compact disks along with a quantitative estimation. Using quantitative methods, we also obtain an upper estimate in the simultaneous approximation by and exact degrees of approximation estimation for these operators' Stancu-type generalization.

La mayoría de la problemática que aborda este estudio viene referida a personas con dificultades para comprender y tomar decisiones, incluyendo la comprensión de las consecuencias de las conductas que realicen causando daño a terceros. Por lo que, a efectos de responsabilidad civil y penal habrá de repararse, necesariamente, pero sin etiquetas, en la discapacidad intelectual, que es diversa y de etiología múltiple. Así, en materia de responsabilidad civil extracontractual, la capacidad de responder civilmente ha estado vinculada tradicionalmente y de forma directa con la capacidad de obrar. Tras el cambio de paradigma y nuevo enfoque de la capacidad jurídica, la Ley 8/2021 de 2 de junio, opera una modificación en la materia, que merece ser objeto de atención. De ahí la oportunidad de la presente Monografía y las valiosas aportaciones que de ella se extraen.

Objective:
Sputum cytology is recognized as a straightforward and noninvasive way to diagnose lung cancer, although its clinical utility has not yet been investigated. The objective of the study was to detect and classify cancerous cells in sputum by examining their expression of minichromosome maintenance proteins (MCM2 and MCM7). In addition, the study attempted to evaluate these proteins’ potential as biomarkers of lung cancer lesions and their relationships with clinicopathological characteristics.

Material and Methods:
MCM2 and MCM7 expression in sputum samples was evaluated using immunocytochemistry in sputum cell blocks (n = 97), and their correlation with clinicopathological features was examined. Diagnostic performance was evaluated as a function of sensitivity and specificity.

Results:
Immunoexpression of MCM2 and MCM7 was confined to the nuclei of malignant cells alone, suggesting its potential as a differential diagnostic marker. They showed significant correlations with tumor cytology (P < 0.001), while MCM7 alone exhibited a significant correlation with tumor stage (P = 0.014). The overexpression of these markers was notably pronounced in lung adenocarcinoma compared to other subtypes. In terms of characterizing malignant cells, MCM7 protein demonstrated the highest sensitivity at 92% with an area under the curve (AUC) of 0.961, whereas MCM2 had a sensitivity of 80% and AUC of 0.901.

Conclusion:
This study presents the inaugural use of MCM7 immunocytochemistry on exfoliated cells in sputum samples, proposing that analyzing immunocytochemical markers in sputum could serve as a cost-effective approach for diagnosing lung cancer. Integrating these assessed markers into routine cytopathology laboratories could augment traditional morphological evaluations, thereby improving the sensitivity of sputum cytology.

Published: December 2024

The UAE is well-known country in providing a high-quality technology-based healthcare. Almost all hospitals in the UAE deploy HIS in public and private hospitals, but this progress is not free from obstacles and challenges. A lack of expertise is the major problem to successfully deploying HIS by hospitals. Despite the ongoing expansion of healthcare technologies in the UAE, there is an absence of a framework that explain how the quality attributes of HIS (system quality, information quality, and service quality) contribute to patients’ satisfaction and boost the intention to use the system on regular bases. Determining the significance of these relationships is crucial to evaluate the framework that correlated them together towards better healthcare service. The aim of this study is to validate the Delone and McLean success model in healthcare domain, in particular the adoption of HIS in Al-Sharjah public hospitals Hence, quantitative methodology based on SEM was adopted to achieve this aim. A number of 428 questionnaires out of 500 distributed copies were used for data analysis. The result revealed that system quality, information quality, and service quality have significant effect on patient satisfaction and the intention to use HIS on regular bases.

Along with the times, false information easily spreads, including in Indonesia. In Press Release No.485/HM/KOMINFO/12/2021 the Ministry of Communication and Information has cut off access to 565,449 negative content and published 1,773 clarifications on hoax and disinformation content. Research has been carried out regarding this matter, but it is necessary to classify fake news into disinformation and hoaxes. This study presents a comparison between our proposed model, which is an ensemble of shallow learning predictive models, namely Random Forest, Passive Aggressive Classifier, and Cosine Similarity, and the deep learning model that uses BERT-Indo for classification. Both models are trained using equivalent datasets, which contain 8757 news, consisting of 3000 valid news, 3000 hoax news, and 2757 disinformation news. These news were obtained from websites such as CNN, Kompas, Detik, Kominfo, Temanggung Mediacenter, Hoaxdb Aceh, Turnback Hoax, and Antara, which were then cleaned from all unnecessary substances, such as punctuation marks, numbers, Unicode, stopwords, and suffixes using the Sastrawi library. At the benchmarking stage, the shallow learning model is evaluated to increase accuracy by applying ensemble learning combined using hard voting. This results in higher values, with an accuracy of 98.125%, precision of 98.2%, F-1 score of 98.1%, and recall of 98.1%, compared to the BERT-Indo model which only achieved 96.918% accuracy, 96.069% precision, 96.937% F-1 score, and 96.882% recall. Based on the accuracy value, shallow learning model is superior to deep learning model. This machine learning model is expected to be used to combat the spread of hoaxes and disinformation in Indonesian news. Additionally, with this research, false news can be classified in more detail, both as hoaxes and disinformation

Lanjut usia merupakan proses seumur hidup yang ditandai dengan bertambahnya usia baik pada tingkat seluler, organ, atau seluruh tubuh yang terjadi sepanjang rentang kehidupan individu, yang pada akhirnya akan mengalami perubahan terdiri dari perubahan fisik, sosial, dan psikologis. Kondisi lansia rentan mengalami perubahan status kesehatan, yang menyebabkan kemunduran serta ketidakmampuan dalam melakukan kegiatan dan memenuhi kebutuhannya sehari-hari, sehingga membutuhkan perawatan jangka panjang. Perawatan jangka panjang menimbulkan dampak pada keluarga berupa beban yang dihadapi keluarga, yang dapat mempengaruhi kualitas hidup keluarga, terutama pada anggota keluarga yang bertindak sebagai caregiver. Kualitas hidup caregiver informal dapat dipengaruhi oleh jenis penyakit dan status fungsional lansia. Penelitian ini merupakan penelitian non-eksperimental dengan desain studi cross-sectional. Tujuan penelitian ini adalah untuk menganalisa faktor jenis penyakit dan status fungsional lansia yang mempengaruhi kualitas hidup caregiver informal lansia dengan penyakit kronis. Sampel penelitian ini berjumlah 109 responden. Hasil analisa data menggunakan regresi logistik sederhana didapatkan hasil bahwa variabel independen yang paling berhubungan adalah status fungsional lansia, dengan p-value <0,05, OR=8,84. Hasil penelitian menunjukkan bahwa status fungsional berhubungan secara signifikan dengan kualitas hidup caregiver lansia, jika kondisi status fungsional lansia mandiri atau independent maka kualitas hidup caregiver informal lansia baik, status fungsional lansia yang rendah memiliki risiko 8 kali lebih besar untuk membuat kualitas hidup caregiver lansia rendah, dibandingkan dengan lansia yang memiliki status fungsional mandiri atau independent. Lansia dengan penyakit kronis yang memiliki status ADL total atau sebagian dibantu, secara fisik dan emosional semakin meningkatkan beban caregiver informal lansia dalam memberikan perawatan. Beban ini mempengaruhi kualitas hidup caregiver informal lansia. Perawat sebagai pemberi layanan kesehatan keluarga hendaknya memberikan asuhan keperawatan secara komprehensif. Perawat diharapkan mampu meningkatkan dan menjaga pemenuhan kebutuhan manusia secara komprehensif bagi lansia dengan penyakit kronis dan caregiver informalnya, sehingga kualitas hidup lansia, caregiver informal, dan keluarganya tetap optimal.
