Laparoscopic assistance by operating room nurses: Results of a virtual-reality study
2016
Abstract Background Laparoscopic assistance is often entrusted to a less experienced resident, medical student, or operating room nurse. Data regarding laparoscopic training for operating room nurses are not available. Objectives The aim of the study was to analyse the initial performance level and learning curves of operating room nurses in basic laparoscopic surgery compared with medical students and surgical residents to determine their ability to assist with this type of procedure. Design The study was designed to compare the initial virtual reality performance level and learning curves of user groups to analyse competence in laparoscopic assistance. Participants The study subjects were…
Management of Bleeding Complications in Virtual Reality Laparoscopy
2019
The aim of this study was to compare the impact of induced bleeding complication training with regular training on a virtual reality laparoscopic (VRL) simulator. Although bleeding complications occur rarely during laparoscopic surgery, they usually arise without warning and may have severe consequences for the patient because complication management training is not currently widespread. Third-year medical students (n = 41) were randomly selected for 2 curricular courses on how to perform a bimanual task on a VRL simulator. Both the regular training group (RTG) and the induced bleeding complication training (ICT) group performed 2 regular training sessions and 9 training sessions. For the I…
AR METHODS FOR THE VISUALIZATION OF THE LOST MARBLE “TRIBUNA” IN THE MAIN APSE OF THE CATHEDRAL OF PALERMO
2022
Abstract. In recent years research works have shown that augmented reality tools can offer effective support for the dissemination of architectural heritage, when integrated into the information data extracted with surveying and representation tools and further data from other sources, e.g., history.The development and permanent updating of software platforms dedicated to augmented reality, i.e., Apple's ARKit and Google's ARCore, as well as the introduction of new features, offer today affordable support for the development of AR solutions.Some operational difficulties are due to the rapid and constant evolution of the technologies; the available solutions can be compared to prototypes and…
Cultural and historical research on character and virtue education in Latvia in an international perspective
2019
This report summarizes the research work implemented during the second activity “Cultural and historical research of character and virtue education in Latvia in an international perspective” of the project “Modernization of school education in Latvia through an innovative research-based programme on 21st century competences and virtue ethics development supported by a virtual campus (ARETE-school)” - 1.1.1.2/VIAA/1/16/071. The research questions that guided the research process during this activity were: What are the theories and practices of character and virtue education in the international arena? How are teachers trained for teaching character and virtue education? How can the past and …
Lisätty todellisuus matkapuhelinsovelluksissa
2010
Peura, Kimmo Tapio Lisätty todellisuus matkapuhelinsovelluksissa Jyväskylä: Jyväskylän yliopisto, 2010. 30s. Kandidaatintutkielma Tässä tutkielmassa käsitellään lisättyä todellisuutta ja sen sovelluksia matkapuhelimissa. Ensin esittelen, mitä lisätty todellisuus on ja miten se liittyy virtuaalitodellisuuteen. Tämän jälkeen kerron matkapuhelimesta lisätyn todellisuuden laitealustana. Lopuksi esittelen kolme matkapuhelinsovellusta, Layarin, Sekai Cameran ja Toozlan, joissa hyödynnetään lisättyä todellisuutta. Lisätty todellisuus toteutetaan yleensä käyttämällä läpinäkyviä näyttöjä tai monitoripohjaisia näyttöjä. Läpinäkyvät näytöt ovat usein päässä kannettavia näyttöjä ja niiden avulla voi t…
A nested virtualization tool for information technology practical education
2016
Background A common problem of some information technology courses is the difficulty of providing practical exercises. Although different approaches have been followed to solve this problem, it is still an open issue, specially in security and computer network courses. Results This paper proposes NETinVM, a tool based on nested virtualization that includes a fully functional lab, comprising several computers and networks, in a single virtual machine. It also analyzes and evaluates how it has been used in different teaching environments. Conclusions The results show that this tool makes it possible to perform demos, labs and practical exercises, greatly appreciated by the students, that woul…
El camino hacia el reconocimiento legal de la violencia sexual contra la mujer en tiempos de guerra
2020
El objetivo de este trabajo es explorar el proceso de configuración de un Derecho Internacional que atienda al fenómeno de la violencia sexual contra las mujeres en contextos de conflictos armados, analizando el alcance del cambio de paradigma logrado en los años noventa con la tipificación y enjuiciamiento de la violencia sexual contra las mujeres en conflictos armados en el ámbito de la justicia penal internacional y, en última instancia, identificando posibles elementos sobre los que seguir avanzando hacia un Derecho Internacional que reconozca un estatus jurídico de las mujeres y huya de la imagen única de la mujer como víctima. © 2020 University of Valencia, Human Rights Institute.

Molecular dynamics, dynamic site mapping, and highthroughput virtual screening on leptin and the Ob receptor as anti-obesity target.
2014
Body weight control is a mechanism finely regulated by several hormonal, metabolic, and nervous pathways. The leptin receptor (Ob-R) is crucial for energy homeostasis and regulation of food uptake. Leptin is a 16 kDa hormone that is mainly secreted by fat cells into the bloodstream, and under normal circumstances, circulating levels are proportionate to the fat body mass. Sensing of elevated leptin levels by the hypothalamic neurocircutry activates a negative feedback loop resulting in reduced food intake and increased energy expenditure. Decreased concentrations lead to opposite effects. Therefore rational design of leptin agonists constitute an appealing challenge in the battle against ob…
Elogio delle virtù nell’immagine politica di Giuliano in Libanio
2014
Libanius’ Julianic orations play an important role to move closer to knowledge of the interior portrait of this emperor. Julian’s personality is based on four virtues: philoponia, phronesis, philanthropia, sophrosyne. These virtues are panegyrical topoi in the eulogy of the rulers (Basilikos logos), and in the Libanian context they are freely reused, adapted to the present in order to return an image of Julian politically useful; all this doesn’t necessarily imply systematic distortion of the truth. In this connection, Julian’s political image is the exact opposite of the image of his predecessor: the reader is given the conviction that Constance, unlike Julian, would have achieved only a s…
Moral Neuroeducation, Ethics of Justice and Pluralism
2019
In order to design a model of moral neuroeducation for pluralistic and democratic societies three core issues need to be addressed in-depth: firstly, the cerebral basis of moral behaviour (neuroethics); secondly, how neuroscientific knowledge can be engaged in the teaching of moral education (moral neuroeducation); and finally, the specific ethical model underpinning this area of education (moral and political philosophy). The last of these three issues is the focus of this chapter, as it is fundamental to the whole project of moral neuroeducation, and it structures the approach to moral neuroeducation proposed in this chapter. Drawing on the conceptual framework of Adela Cortina’s ethics o…
