Virtual Guide On Ocular Self-Examination To Support The Self-Care Practice For People With HIV/AIDS

Objetivou-se descrever processo de desenvolvimento da cartilha virtual sobre autoexame ocular para pessoas com HIV/aids. A proposta metodológica seguiu as cinco etapas preconizadas por Falkembach: análise e planejamento, modelagem, implementação, avaliação e distribuição. A adequação da versão impressa para virtual requereu a construção de um vídeo tutorial, agregação de fotos ilustrativas para visualização de possíveis alterações oculares e ferramenta de interatividade com demonstração do resultado do exame ao usuário. Na avaliação inicial do material, foram diagnosticadas falhas no layout. Assim, comandos foram recolocados, unificados, dispostos em local de fácil visualização e foi feita a adequação da linguagem. Considera-se possível promover aproximação do usuário com métodos de prevenção na área da saúde ocular por meio de cartilha virtual, contribuindo para desenvolvimento de habilidades e divulgação do autoexame.


Evaluation of Virtual Reality Snowplow Simulator Training: A Literature Review, September 2006

Each winter, the Iowa Department of Transportation (Iowa DOT) maintenance operators are primarily responsible for plowing snow off federal and state roads. Drivers typically work long shifts under treacherous conditions. In addition to properly navigating the vehicle, drivers are required to operate several plowing mechanisms simultaneously, such as plow controls and salt sprayers. However, operators have few opportunities during the year to practice and refine their skills. An ideal training program would provide operators with the opportunity to practice these skills under realistic yet safe conditions, as well as provide basic training to novice or less-experienced operators. Recent technological advancements have made driving simulators a desirable training and research tool. This literature review discusses much of the recent research establishing simulator fidelity and espousing its applicability. Additionally, this report provides a summary of behavioral and eye tracking research involving driving simulators. Other research topics include comparisons between novice and expert drivers’ behavioral patterns, methods for avoiding cybersickness in virtual environments, and a synopsis of current personality measures with respect to job performance and driving performance. This literature review coincides with a study designed to examine the effectiveness of virtual reality snowplow simulator training for current maintenance operators, using the TranSim VS III truck and snowplow simulator recently purchased by the Iowa DOT.

Virtual Environment: assistance in nursing care for the deaf based on the protocol of Primary Care

Objective: Presenting a Virtual Environment (VE) based on the Protocol of Treatment of Hypertension and Diabetes Mellitus type 2, used in Primary Care for evaluation of dietary habits in nursing consultations. Method: An experimental study applied by two nurses and a nurse manager, in a sample of 30 deaf patients aged between 30 and 60 years. The environment was built in Visual Basic NET and offered eight screens about feeding containing food pictures, videos in Libras (Brazilian sign language) and audio. The analysis of the VE was done through questionnaires applied to patients and professionals by the Poisson statistical test. Results: The VE shows the possible diagnostics in red, yellow, green and blue colors, depending on the degree of patients’ need. Conclusion: The environment obtained excellent acceptance by patients and nurses, allowing great interaction between them, even without an interpreter. The time in consultation was reduced to 15 minutes, with the preservation of patient privacy.

Museu Virtual da Cidade Velha

Na actual sociedade da informação, a internet tem-se afirmando enquanto ferramenta de comunicação e fonte de informação, tornando importante que as mais variadas instituições marquem presença neste mundo digital online. Neste contexto, os museus têm vindo a adoptar estas ferramentas na sua relação com os públicos, sendo importante o conhecimento da realidade internacional. Assim, o presente trabalho de investigação teve por objectivos a determinação tanto dos conteúdos disponibilizados pelos museus virtuais como das ferramentas disponíveis para o desenvolvimento do Museu Virtual da Cidade Velha. Para tal, foi feita uma análise de alguns museus virtuais existentes que foram importantes para as tomadas de decisão durante o desenvolvimento do Museu da Cidade Velha. No que respeita aos conteúdos disponibilizados nos museus analisados podemos concluir que estes oferecem, sobretudo, informações de apresentação do museu, sobre colecções, exposições físicas e trabalhos de serviços educativos, sendo essa a forma de comunicação privilegiada em termos de internet. Realizou-se ainda, uma fundamentação teórica acerca dos principais conceitos relativos a museu virtual. Também foi feito um estudo sobre as tecnologias de implementação Web nomeadamente o Joomla e o DNN. Das conclusões tiradas com base nas análises, foi feito uma implementação de um protótipo para o Museu Virtual da Cidade Velha que poderá ser acessível através da Web.

Evaluation of Virtual Reality Snowplow Simulator Training, January 2007

Each winter, Iowa Department of Transportation (Iowa DOT) maintenance operators are responsible for plowing snow off federal and state roads in Iowa. Drivers typically work long shifts under treacherous conditions. In addition to properly navigating the vehicle, drivers are required to operate several plowing mechanisms simultaneously, such as plow controls and salt spreaders. There is little opportunity for practicing these skills in real-world situations. A virtual reality training program would provide operators with the opportunity to practice these skills under realistic yet safe conditions, as well as provide basic training to novice or less-experienced operators. In order to provide such training to snowplow operators in Iowa, the Iowa DOT purchased a snowplow simulator. The Iowa DOT commissioned a study through Iowa State University designed to (1) assess the use of this simulator as a training tool and (2) examine personality and other characteristics associated with being an experienced snowplow operator. The results of this study suggest that Iowa DOT operators of all ages and levels of experience enjoyed and seemed to benefit from virtual reality snowplow simulator training. Simulator sickness ratings were relatively low, implying that the simulator is appropriate for training a wide range of Iowa DOT operators. Many reported that simulator training was the most useful aspect of training for them.

Three essays on organizations and their external environment

Abstract: The literature on the various links between organizations and their external environment is very extensive and fragmented. This thesis is comprised of three separate essays, each examining specific research questions related to these links. The first essay deals with the notion of industry life cycle and how the geographical concentration of an industry is linked to the particular life cycle stage in which the industry finds itself. The aim of this first essay is firstly to verify if the evolution of the Swiss hotel industry fits some of the stylized facts of the industry life cycle. The second aim is to verify if there is evidence of geographical clustering of the hotel industry, and by extension of tourism. The third aim is to verify a hypothesis that industry decline manifests itself mainly by company closures in decentralized locations. The importance for organizational survival and performance of adapting and reacting to environmental changes has long been ascertained. This adaptation requires managers, under conditions of uncertainty, to identify relevant changes in their external environment and to interpret the possible effects of those changes on their organization. Furthermore, it requires finding and adopting organizational responses in reaction to the environmental changes. The second essay explores how managers perceive their environment by reporting the results of two workshops held with managers from the European hotel industry. In the third essay we examine in more detail the role of uncertainty in the interpretation by executives of environmental changes. We integrate existing theories of interpretation and uncertainty into one framework, which we then test using national survey data from the hotel industry. In all three essays we are able to provide some evidence to support our main hypotheses, but.also make suggestions far further research into the topics examined.

Institutional constraints on organizations: The case of Spanish car dealerships

We study the effect of organizational choice and institutions on the performance ofSpanish car dealerships. Using outlet-level data from 1994, we find that verticallyintegrateddealerships showed substantially lower labor productivity, higher labor costs andlower profitability than franchised ones. Despite these gaps in performance, no verticallyintegratedoutlet was separated until 1994, yet the few outlets that were eventuallyseparated systematically improved their performance. We argue that the conversion ofintegrated outlets into franchised ones involved significant transaction costs, due to aninstitutional environment favoring permanent, highly-unionized employment relations. Inline with this argument, we find that the observed separations occurred in distributionnetworks that underwent marked reductions in worker unionization rates, following thelegalization of temporary labor contracts.

The benefits of limited feedback in organizations

In most firms, managers periodically assess workers' performance. Evidence suggeststhat managers withhold information during these reviews, and some observersargue that this necessarily reduces surplus. This paper assesses the validity of thisargument when workers have career concerns. Disclosure has two effects: it exposesthe worker to uncertainty about future effort levels, but allows him to use current effortto influence his employer's beliefs about future effort. The surplus-maximizingdisclosure policy reveals output realizations in the center of the distribution, butnot in the tails. Thus, it is efficient for firms to reveal some but not all performanceinformation.
