Is Virtual Reality a Game Changer in Pediatrics' Acute Pain Perception?
No full textPurpose of review: Virtual reality (VR) is a promising tool that is becoming increasingly popular for the prevention and treatment of procedural pain in children. This review aims to investigate the current literature on the use and effectiveness of VR in paediatric procedural pain management, focusing on needle-related procedures, burn wound care, dental procedures among others; limitations and future perspectives on the use of VR will also be highlighted.
Recent findings: in addition to the most researched fields of application (e.g. needle procedures), VR has also started to be used in new areas, such as nasal and gastrointestinal endoscopies as well as minor surgeries. From the latest evidence, VR seems to be effective in many procedures, especially compared to no distraction; however, there is conflicting data in the literature due to numerous factors such as differences between technologies, degree of VR-immersion, patients coping styles among others.
Summary: there are still no data of absolute certainty on the effectiveness of VR in reducing procedural pain in paediatric patients and data pooling is still difficult. Future research should carry on large randomised-controlled, multicentre studies to better define VR properties and how best to optimise VR software and user experience for maximum pain reduction
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
High quality syngas production via steam-oxygen blown bubbling fluidised bed gasifier
No full textThis paper presents experimental and modelling results of fuel gas obtained in a steam-oxygen blown fluidised bed pilot scale (500 kWth) coal gasifier that is part of the ZECOMIX (Zero Emission of CarbOn with MIXed Technologies) research infrastructure run by ENEA. As there is poor information about start up and steady state operation of fluidised bed gasifiers at such a scale, in this work we investigated the influence of some important parameters such as coal ignition temperature, feeding rate of particulate bed material (olivine sand) and transition from oxidant to reducing environment. The experimental runs confirmed the crucial importance of S/O (steam/oxygen) ratio on the product gas composition. High quality syngas (low content of methane, below 1.0 v/v %, and high content of H2 and CO: CO + H2 61.0 v/v%) was obtained with S/O = 1.1.A shortcut model of the gasifier was also formulated, considering instantaneous coal pyrolysis, kinetics of coke steam reforming reactions in the fluidised bed, and achievement of thermodynamic equilibrium for the water gas shift reaction. The model takes into consideration the average residence time of coke particles into the gasifier: since this is a characteristic parameter of the reactor, the performance of different fluidised bed gasifiers can be simulated

Software VirtualBox (v 7.0)
Software Ubuntu Linux Metasploitable2
sobre el sistema operativo windows 11 (máquina fisica base)
El software VirtualBox es un software para crear máquinas virtuales dentro de la máquina física. Se hace una virtualización creando en este caso 2 máquinas virtuales que fueron las máquinas de Kali Linux (mv examinador) y el servidor Linux vulnerable (mv empresa) la cual es la que tiene las vulnerabilidades y es llamada mv metasploitable2. Estos software se instalaron en un PC portátil HP con el sistema operativo Windows 11 que es la máquina física que se utilizó para todo el proceso del pentesting en este proyecto.
Luego de descargadas las imágenes ISO se procede a instalarlas en VirtualBox una por una siguiendo unos pasos en la instalación. Después de instalados ambos sistemas operativos se procedió a hacer la configuración de la red de ambas maquinas dentro del VirtualBox , se conectan en forma “Red Interna” la cual significa que ambas máquinas virtuales están conectadas entre si de forma directa pero sin estar conectadas a la máquina física (Windows 11).
Después de instaladas y configuradas ambas máquinas virtuales (Kali Linux y metasploitable2) se procede a utilizar las herramientas de Kali Linux hacia la máquina víctima que es la empresa para realizar el proceso de escaneo, explotación y acceso a los diferentes servicios de la máquina victima a través de la red simulada, estas herramientas son: Metasploit y Nmap.
Luego de realizar el escaneo de puertos, explotación y el haber logrado el acceso a cada servicio de la máquina virtual víctima, se procede a elaborar las políticas de seguridad respectivas en base al resultado obtenido en los pasos anteriores del pentesting
Využití sociálních médií v B2B prodeji
No full textTato diplomová práce se zabývá tím, jak mohou B2B obchodníci využívat sociální média v prodeji. Na základě systematické rešerše literatury, autor zjistil, že akademici, zkoumající danou problematiku, navrhují další výzkum, a to: v kterých konkrétních krocích se dají využít sociální média v prodeji (Salo, 2017). Autor se na základě toho rozhodl zjistit, jaké sociální sítě, různé technologie a pluginy se dají využít v B2B prodeji - tzv. social sellingu. Social selling se v této práci týká primárně procesu akvizice a okrajově péčí o stávající zákazníky. Autor si vybral kvalitativní průzkum pomocí 10 hloubkových polo-strukturovaných rozhovorů, aby odhalil jak, která sociální média to jsou, tak i motivaci prodejců, proč tato média používat/nepoužívat. Aby autor dodržel správnost vyhodnocení výsledků, data byla analyzována pomocí Tématické analýzy, která v této studii vykrystalizovala 2 hlavní strategické přístupy v social sellingu. Tyto přístupy (tzv. Push a Pull strategie) obsahují praktické příklady a konkrétní aktivity, které mohou prodejci využívat v každodenní praxi. Tyto výsledky jsou prezentovány s důrazem na praktičnost a jednoduchost implementace. Tvoří proto hlavní přínos autorovo výzkumu. V poslední části autor zmiňuje výzvy a manažerská doporučení, které mohou obchodníci využít v každodenním pracovním životě.This diploma thesis focuses on social media usage in B2B sales. Based on the systematic literature review conducted by the author, he has found out that recent researchers (Salo, 2017) suggest further research in the area of how and in which sales phase should various social networking sites, technologies and plugins used. To further fill this research gap, author decided to identify these social media and their usage among B2B salespeople in the so-called social selling process. The social selling process in this thesis applies mainly to acquiring new prospects and tangentially to taking care of existing clients (follow-up step). Author has chosen a qualitative research method via conducting 10 in-depth semi-structured interviews to reveal these instruments as well as motivation of a sales person on why to use social media in the selling process. The collected data was analyzed using Thematic analysis to ensure the right procedure and to identify main themes which crystalized into 2 main strategic approaches in social selling. These approaches (Push and Pull) include practical examples of concrete activities which sales people can use in their daily jobs and are presented with focus on practicality and ease of implementation. These also form the main contribution of author`s research. In the last part, author mentions challenges in social selling and recommended managerial implications for salesforce
TeX v jednoduchém unixovém prostředí
No full textsummary:Při ladění TeXového dokumentu potřebujeme mnohokrát opakovaně pouštět TeX, podívat se, jak dopadl výsledek v prohlížeči DVI nebo PDF souboru, mrknout na výpis TeXu na terminálu, podívat se případně do logu a celou činnost opakovat. V tomto článku je ukázáno, jak tuto práci dělá autor článku. Proces "editor-TeX-kuk" je zde podporován jednoduchými unixovými nástroji: bashovým skriptem texloop, který si autor pro tyto účely vytvořil, dále terminálem Xterm a jednoduchým editorem, který umí navázat na klávesovou zkratku spuštění příkazu v systému. Čtenář se zde může inspirovat a přizpůsobit tyto nástroje svým vlastním potřebám. V článku je popsána funkce skriptu texloop, dále je neformálně rozveden dlouholetý vývoj autorova vztahu k textovým editorům a konečně je zde uvedena konfigurace terminálu Xterm, aby vyhovoval českému prostředí jak v kódování ISO-8859-2, tak v kódování UTF-8. Pro kódování UTF-8 si v závěru článku vygenerujeme TeXový formát csplain.summary:By debugging a TeX document it is necessary many times repeatedly to run TeX, to look for the result in DVI or PDF file, to gander the TeX output on the terminal, or eventually to have a look in the log-file, and all that action to repeat. In the paper it is show, how this work is made by author. The process '‘'editor-TeX-look' is supported by simple Unix tools: bash script texloop, created by author for these purposes, Xterm terminal and a simple editor, which is able to link to the shortcut key the activation of a system command. The reader could be inspired with the solution and to adapt these tools to his/her own needs. In the paper the function of the texloop script is described, and further the longstanding evolution of the author's relation to text editors is informal elaborated and finally a configuration of Xterm terminal, suitable for the czech environment with both ISO-8859-2 and UTF-8 encoding is introduced. For UTF-8 encoding the TeX format csplain is generated at the end of the paper
Cardiovascular involvement in children with inflammatory bowel disease: the experience of an Italian tertiary centre
No full textINTRODUCTION: Cardiovascular involvement in paediatric inflammatory bowel disease (PIBD) is rarely described; aetiology is either driven by medications or IBD itself. We report a case-series of PIBD patients with cardiovascular involvement in an Italian tertiary centre.
Methods: We retrospectively reviewed the clinical records of 221 PIBD patients followed-up in our centre (01/2021 - 01/2024). We identified 3/221 (1.4%) patients with history of cardiovascular involvement for whom we collected demographic, clinical and treatment data.
Results: Overall, 2/3 patients with Crohn’s disease (Paris classification A1aL3L4aB1G1 and A1aL3L4aB1pG1) were diagnosed with pericarditis, 1/3 with ulcerative colitis (Paris classification E1S0) developed myopericarditis. All patients were male; median age at
carditis onset was 12.5 years (range 9-15) with a median time between IBD onset and carditis of 26 months (range 1-72). All patients presented with chest pain worsened by clinostatism, only one had concomitant fever. Concerning pericarditis patients, at
carditis onset one had mildly active disease while on oral mesalazine and the second was on no medical treatment after having received ileocolic resection 2 months earlier. The myopericarditis patient was in remission on rectal mesalazine, having received COVID-19 mRNA vaccine 3 days earlier. Pericarditis were treated with non-steroidal
anti-inflammatory drugs while myopericarditis with oral corticosteroids. All patients recovered fully without apparent sequelae.
Conclusion: Cardiovascular involvement in PIBD is infrequent but remains a potential complication that warrants attention. In our experience, pericarditis appeared to be related to IBD itself, whereas myopericarditis remained of uncertain aetiology. Clinicians should
maintain a low threshold for diagnosis in case of suggestive symptomatology to allow a prompt management
