Network Control Systems (NAC) have been used in many industrial processes. They aim to reduce the human factor burden and efficiently handle the complex process and communication of those systems. Supervisory control and data acquisition (SCADA) systems are used in industrial, infrastructure and facility processes (e.g. manufacturing , fabrication, oil and water pipelines, building ventilation, etc.) Like other Internet of Things (IoT) implementations, SCADA systems are vulnerable to cyber-attacks, therefore, a robust anomaly detection is a major requirement. However, having an accurate anomaly detection system is not an easy task, due to the difficulty to differentiate between cyber-attacks and system internal failures (e.g. hardware failures). In this paper, we present a model that detects anomaly events in a water system controlled by SCADA. Six Machine Learning techniques have been used in building and evaluating the model. The model classifies different anomaly events including hardware failures (e.g. sensor failures), sabotage and cyber-attacks (e.g. DoS and Spoofing). Unlike other detection systems, our proposed work helps in accelerating the mitigation process by notifying the operator with additional information when an anomaly occurs. This additional information includes the probability and confidence level of event(s) occurring. The model is trained and tested using a real-world dataset.

Peran orangtua sangat diperlukan dalam penggunaan gadget pada anak usia dini, agar anak tidak merasa asing dalam menghadapi berbagai peralatan yang berteknologi canggih. Penelitian ini bertujuan untuk melihat dan mengetahui pandangan serta pengalaman orang tua dalam mengenalkan penggunaan gadget pada anak usia dini. Penelitian ini menggunakan pendekatan kualitatif dengan metode penelitian fenomenologi. Pengambilan subjek dilakukan dengan cara mewawancarai di dua keluarga partisipan yang terdiri dari orang tua pria dan wanita, dari berbagai profesi masing-masing dan mempunyai anak yang sudah dikenalkan gadget, sasaran anak usia dini berumur sekitar 3-6 tahun di Palembang. Hasil penelitian mengidentifikasi bahwa pandangan orangtua yang negatif terhadap gadget mengakibatkan kesulitan yang lebih besar bagi mereka dalam interaksi keterlibatan pada anak, sementara orangtua dengan pandangan positif cenderung lebih percaya diri dalam keterlibatan mereka. Selanjutnya pada pengalaman orangtua...

En este capítulo, se exponen los resultados de las actuaciones que se han llevado a cabo durante la ejecución del Proyecto de consolidación y puesta en valor de la zona arqueológica de las Dunas de Guardamar, que se gestó a partir de 2014 y se pudo ejecutar entre 2019 y 2021, los cuales han permitido cambiar totalmente la dinámica de este excepcional conjunto arqueológico, pasando así del olvido a una puesta en valor muy atractiva, funcional y con una carga didáctica modélica.

We explore the role of two metaphors for innovation and infrastructure integration in the development of a regional patient portal. Our premise is that metaphors have real consequences for agenda setting and decision-making; we view them as operationalizations of sociotechnical imaginaries. Drawing on our formative study of the portal project, we focus on the generative character of metaphors and argue that they are constitutive elements of information infrastructures. While the two metaphors in our study helped to make imaginaries of ‘integrated’ and ‘personalized’ health care more definite, cognizable, and classifiable, they also concealed the politics of infrastructural work. We argue that the act of ‘spelling out’ metaphors can open up a space for new imaginaries and alternative strategies. With this study we aim to contribute to existing knowledge about infrastructural work, and to renew the interest among STS scholars for the role of discursive attributes in information infras...

Objectives: To investigate the effect of 16% carbamide peroxide bleaching gel on surface micromorphology and roughness of enamel and root dentin of uremic patients receiving hemodialysis using atomic force microscopy (AFM).Methods: A total of 20 sound molars were collected from healthy individuals (n=10) and uremic patients (n=10). The roots were separated from their crowns at the cemento-enamel junction. Dental slabs (3 mm x 2 mm x 2 mm) were obtained from the buccal surface for enamel slabs and the cervical third of the root surface for dentin slabs. Dental slabs were then flattened and serially polished up to #2500-grit roughness using silicon carbide abrasive papers. Half of the slabs obtained from healthy individuals and uremic patients were stored in artificial saliva and left without bleaching for control and comparison. The remaining half was subjected to a bleaching treatment using 16% carbamide peroxide gel (Polanight, SDI Limited) 8 h/day for 14 days and stored in artific...
