DO VIRTUAL AO REAL: COMUNICAÇÃO, SEXO E INTERNET

Este trabalho é um estudo exploratório sobre o Ambiente Comunicacional Internet que investiga tanto a possibilidade da influência de suas ferramentas de interação/comunicação sobre o comportamento sexual e de risco quanto o desenvolvimento de comportamento compulsivo no uso destas ferramentas na busca de parceiros sexuais. A metodologia adotada é, além da pesquisa bibliográfica, a da pesquisa exploratória, um levantamento e análise de dados quantitativos e pode ser considerada como pertencente ao paradigma tradicional empírico, pois a coleta de dados foi baseada em respostas a questionários semi-estruturados, aplicados a um grupo de informação composto por 428 estudantes universitários dos cursos ligados à área de Computação e Informática de uma instituição particular de Ensino Superior do município de São Paulo SP, Brasil. Para isso, obedece à Resolução do Conselho Nacional de Saúde CNS 196/96 e conta com o TCLE. Os resultados indicam que as práticas sexuais, a exposição a DST e vírus HIV e, particularmente, a tendência ao desenvolvimento do Transtorno de Adicção à Internet se distinguem de modo irrefutável. Os participantes que alegaram buscar parceiros sexuais reais na Internet são diretos nos seus objetivos, pois quando encontram esse parceiro concretizam o ato sexual, em ambientes impessoais, como por exemplo, o motel, e muitas vezes de modo arriscado no que toca à prevenção e à segurança no contato com outro. Destaca-se, ainda, que a compulsão não é reconhecida pelo grupo e que a procura de parceiros por intermédio das mídias digitais, para esse grupo, não está relacionada a itens negativos quanto a sua qualidade de vida o que suscita o estudo e a discussão mais aprofundada sobre a interação comunicação, sexo e Internet .(AU)

Enhancing Promotional Strategies through the Use of Web 2.0

We have witnessed a rising interest – by both academic and managerial field – in the marketing application of Web 2.0 techniques. Yet the effective impact and change it brings is still unclarified. The importance of Web 2.0 is constantly on the rise. We see consumers join social networks, using social tools in an ever greater number, therefor it gives companies a new and effective tool for marketing communication and other marketing-related activities. In our research, we first aim to clarify the definition and boundaries of Web 2.0. Then through a literature review we collect some of the most important areas of marketing to be affected by this seemingly technological change. We also have a brief overview of challenges and risks firms face in this new environment.

Construção de um ambiente virtual de aprendizagem para aplicação do processo de enfermagem baseado na Nanda International, NOC, NIC e CIPE®

This study aimed to build a virtual learning environment for application of the nursing process based on the NANDA-I, NOC, NIC and ICNP® . Faced with problems related to learning of the nursing process and classifications, there is an urgent need to develop innovative teaching resources that modify the relationship between students and teachers. The methodology was based on the steps inception, development, construction and transition, and the software development process Rational Process Unifield. The team involved in the development of this environment was composed by researchers and students of The Care and Epidemiological Practice in Health and Nursing and Group of the Software Engineering curse of the Federal University Rio Grande do Norte, with the participation of the Lisbon and Porto Schools of Nursing, in Portugal. In the inception stage the inter research communication was in order to define the functions, features and tools for the construction process. In the preparation, step the planning and modeling occurred, which resulted in the creation of a diagram and a architectural drawings that specify the features and functionality of the software. The development, unit testing and integrated in interfaces of the modules and areas (administrator, teacher, student, and construction of the NP). Then the transition step was performed, which showed complete and functioning system, as well as the training and use by researchers with its use in practice. In conclusion, this study allowed for the planning and the construction of an educational technology, and it is expected that its implementation will trigger a substantial change in the learning of the nursing process and classifications, with the student being active agent of the learning process. Later, an assessment will be made of functional performance, which will enable the software development, with a feedback, correction of defects and necessary changes. It is believed that the software increment after the reviews, this tool grow further and help insert this methodology and every language under the educational and health institutions, promoting paradigmatic desired change by nursing.

Open-source virtual bronchoscopy for image guided navigation

This thesis describes the development of an open-source system for virtual bronchoscopy used in combination with electromagnetic instrument tracking. The end application is virtual navigation of the lung for biopsy of early stage cancer nodules. The open-source platform 3D Slicer was used for creating freely available algorithms for virtual bronchscopy. Firstly, the development of an open-source semi-automatic algorithm for prediction of solitary pulmonary nodule malignancy is presented. This approach may help the physician decide whether to proceed with biopsy of the nodule. The user-selected nodule is segmented in order to extract radiological characteristics (i.e., size, location, edge smoothness, calcification presence, cavity wall thickness) which are combined with patient information to calculate likelihood of malignancy. The overall accuracy of the algorithm is shown to be high compared to independent experts' assessment of malignancy. The algorithm is also compared with two different predictors, and our approach is shown to provide the best overall prediction accuracy. The development of an airway segmentation algorithm which extracts the airway tree from surrounding structures on chest Computed Tomography (CT) images is then described. This represents the first fundamental step toward the creation of a virtual bronchoscopy system. Clinical and ex-vivo images are used to evaluate performance of the algorithm. Different CT scan parameters are investigated and parameters for successful airway segmentation are optimized. Slice thickness is the most affecting parameter, while variation of reconstruction kernel and radiation dose is shown to be less critical. Airway segmentation is used to create a 3D rendered model of the airway tree for virtual navigation. Finally, the first open-source virtual bronchoscopy system was combined with electromagnetic tracking of the bronchoscope for the development of a GPS-like system for navigating within the lungs. Tools for pre-procedural planning and for helping with navigation are provided. Registration between the lungs of the patient and the virtually reconstructed airway tree is achieved using a landmark-based approach. In an attempt to reduce difficulties with registration errors, we also implemented a landmark-free registration method based on a balanced airway survey. In-vitro and in-vivo testing showed good accuracy for this registration approach. The centreline of the 3D airway model is extracted and used to compensate for possible registration errors. Tools are provided to select a target for biopsy on the patient CT image, and pathways from the trachea towards the selected targets are automatically created. The pathways guide the physician during navigation, while distance to target information is updated in real-time and presented to the user. During navigation, video from the bronchoscope is streamed and presented to the physician next to the 3D rendered image. The electromagnetic tracking is implemented with 5 DOF sensing that does not provide roll rotation information. An intensity-based image registration approach is implemented to rotate the virtual image according to the bronchoscope's rotations. The virtual bronchoscopy system is shown to be easy to use and accurate in replicating the clinical setting, as demonstrated in the pre-clinical environment of a breathing lung method. Animal studies were performed to evaluate the overall system performance.

An integrated psychology virtual research ethics committee

Research and professional ethics are an integral part of every Psychology degree, as this is seen as a key graduate learning outcome for students leaving to become clinicians working with clients and patients. The development of these skills is embedded in teaching, but they culminate in the final year of a degree when final year students must gain formal ethical approval for their final research project. Decision as to the ethical appropriateness of research are made by a Departmental Research Ethics Committee, which considers all research project proposals submitted by staff and students within the department. One of the challenges of this practice is the scale of work involved for committee members (Doyle & Buckley, 2014) who are all faculty members, and the tracking of applications and decisions, alongside the quality assurance required to ensure that all applications are treated fairly and equally. The time involved in performing this work is often underestimated by Universities, and the variety and complexity of decisions requires extensive discussion and negotiation. Traditionally, these decisions are reached by committee discussions, however this presents logistical difficulties as it requires meetings with quorate attendance. The University of Westminster launched a virtual tool in 2014 to facilitate the management of the Research Ethics Committee, to help track the progress of applications and to allow discussions to occur and be managed virtually. The Department of Psychology adopted the tools in September 2014 to deal with all ethics applications. Here we report on how this virtual committee has affected the role and practices of a working committee that deals with over 300 applications per year, and how an online ethics procedure has facilitated an integrated developmental approach to ethical education.

Real, rubber or virtual: The vision of “one’s own” body as a means for pain modulation. A narrative review

In the last few years a branch of pain research has been focussing on the modulatory effects of the vision of the body on pain perception. So, for instance, the vision of one’s own real body has been proven to induce analgesic effects. On the other hand, bodily illusions such as the rubber hand illusion have provided new tools for the study of perceptual processes during altered body ownership states. Recently, new paradigms of body ownership made use of a technology that is going places both in clinical and in experimental settings, i.e. virtual reality. While the vision of one’s own real body has been proven to yield compelling analgesic effects, slightly more controversial are those attributed to the vision of “owned” dummy bodies. This review will discuss the studies that examined the effects on pain perception of the vision of the own body, with or without body ownership illusions.

Utilização de um ambiente virtual de aprendizagem: um estudo na perspectiva da prática docente

Advances related to information technology are visible and inherent to the management of contemporary organizations, regardless of industrial action. Synchronized with this dynamic, educational institutions are incorporating technological tools that assist its management and academic support to teachers in teaching and interaction with the students. Given that technological innovations are not always taken homogeneously and with the same degree of coverage, remain current and relevant studies on how these technologies are being used in academia. The objective of this research is to identify the usage profile of the functionality of a virtual learning environment related to teaching (undergraduate or postgraduate), demographic variables (age and gender) and institutional (time of admission and academic center of origin.) The methodology applied to the study is descriptive and quantitative. The research is characterized as census, covering all 2152 teachers of undergraduate and graduate students of the Federal University of Rio Grande do Norte, Brazil, who accessed the virtual classes of the Integrated Management of Academic Activities. The study findings revealed that there is a statistically significant difference regarding the use of these tools to teachers who work with undergraduate (49.3%) compared to graduate (6.6%). Regarding gender, women (40.1%) use the system more than men (38.5%). It was also observed that the younger teachers, aged 37 years, are the most active users (42.5%) of the Virtual Class with respect to their elders. For teachers with up to three years time of admission to the UFRN, the pattern of use is more advanced than those with more seniority, as well as the faculty of the Center for Science and Technology are the least likely to use the tools available in relation to other academic centers. It is hoped that with this study managers can direct actions to improve and expand the use of this environment by teachers

Virtual Research Environments Catalysts of Change workshop

Knowledge Exchange organised the workshop 'Virtual Research Environments: Catalysts of change', following the success of the Virtual Research Environments: The next steps workshop which took place in Rotterdam, 2010. Changing research behaviour and practice have repercussions for funding programmes, policy and technology infrastructures. The development of tools has the potential to transform research practice, but as these tools become part of the digital infrastructure, challenges of use, maintenance and sustainably inevitably arise. This workshop allowed Knowledge Exchange and its partners to share their experience and understanding with leading experts, influencers and funders, including members of the European Commission. The workshop offered new perspectives and debate on: changing researcher behaviours policies in the creation and use of VREs sustainability re-use of tools and technologies.

Caracter?sticas del perfil del aprendiz exitoso en un curso de ingl?s (EFL) virtual en el contexto Sena [recurso electr?nico]

This case study presents the general profile of the successful EFL online apprentice in the Colombian public vocational institution, SENA. This profile is described in terms of demographic, academic and cognitive aspects. The demographic profile is composed of features like sex, age, marital status and present job; the academic profile comprises information related to study habits, reasons to study English online, previous English learning experiences and type of ICT tools at home; and the cognitive profile refers to learning styles and EFL learning strategies. Four online surveys addressed to 33 successful online apprentices provide the data, which are also analyzed by means of a basic statistical description supported by Excel. The findings allow the author to conclude that the successful EFL online apprentice in SENA is basically a single person who is unemployed but has access to ICT tools to move forward in his learning process. Additionally, this apprentice has a divergent learning style who prefers the metacognitive, social and memory learning strategies for the EFL online process.
