Assessing Online Courses in Health Education
Authors: Weiss Debra N.
Published: August 2016

Internet-based health education is being used increasingly around the world for two related purposes: 1) to train a global health workforce of nurses, physicians, health educators, and other health workers, and 2) to educate the public about disease prevention and management (e.g., in outbreaks of SARS in China and Ebola in Africa). Assessment of online health education is vital to maintain quality control and to share best practices. Online health education has been found to have significant positive effects on e-learners, comparable to those of traditional face-to-face instruction. In developing countries where there is a critical shortage of health workers, distance education is needed to train large numbers of health workers rapidly and effectively. In developed countries, online health education is a cost-effective means of providing access to 1) higher education for individuals who are employed full time and wish to pursue training in the health professions, 2) workplace continuing education for health professionals, and 3) public health campaigns that promote healthy behaviors. In this chapter we look at what is going on in the field now, and what can be done in the future to use technology to advance the mass dissemination of health education.
Increasing Learner Interaction in Large-Scale Lectures by Using a Mobile Learning Application
Authors: Lehmann Katja , Söllner Matthias , Leimeister Jan Marco
Published: August 2016

Universities face increasing numbers of students leading to increasingly large lectures, and decreasing interaction and feedback, which are important factors for individual learning success and satisfaction. The use of IT can help in overcoming this challenge by increasing the interaction in large-scale lectures without massively increasing the workload of lecturers. This paper presents the design, use and evaluation of a mobile-learning application aiming to increase the interaction in large-scale lectures and the success of learners. For designing the application, the authors follow a design science research approach. The authors rely on insights from interaction theory as well as requirements gathered from lecturers and students in a focus group workshop. With the implementation, large-scale lecture related limitations can be overcome and the results help lecturers to face the according challenges. The results emphasize the potential of IT for university teaching and provide transferable insights for practical use in other learning scenarios.
Mobile Learning in Workforce Development
Authors: McCann Shawn
Published: August 2016

There is potential for higher-order mLearning to enrich action learning teams. Especially as they engage in critical reflection while solving ambiguous, complex challenges by leveraging the affordances of mobile devices. Action learning teams create opportunities to learn from work on real-life challenges. Use of mobile learning can promote higher-order learning while bringing teams together around new ideas where their thinking may be challenged. In this way, action learning teams use mobile devices as tools of convenience to facilitate their learning. Mobile learning extends beyond simple content delivery and provides a platform that can introduce flow and make space for critical reflection. The integration of mobile learning into action learning teams allows for the cultivation of individual creativity and maximization of group virtual or face-to-face meetings. This chapter will discuss the integration of mobile devices and detail multiple mobile learning exercises that action learning teams may use to promote creativity.
Challenges in Implementing the Flipped Classroom Model in Higher Education
Authors: Chellapan Lakshmi , van der Meer Jacques
Published: August 2016

The flipped classroom as typically applied in higher education, consists of delivering lecture material outside of classroom contact, leaving face-to-face class time for more interactive learning, discussion, integration, and application of content (Grant, 2013). Increasing numbers of teachers in higher education are considering implementing this model in light of the perceived benefits of a more active engagement of students in their learning, be it in education, interior designing, medical, sciences, social science, business and management programs (Fulton, 2012; Grant,2013; Roehl, et al. 2013). However, there are challenges in implementing this model. This chapter aims to identify some of the more common challenges. Finally, an example of ‘work in progress' of addressing of these challenges in ‘flipping' the classroom in a first-year university course.
Understanding Flipped Instructions and How They Work In the Real World
Authors: Salifu Shani
Published: August 2016

From Colorado's Pike's Peak into a number of schools, the popularity of flipped classes is on the rise. Based on a two-tier approach to teaching and learning, students review instructor-recommended media or other content in the first tier before face-to-face class meetings, while the second tier has face-to-face classes repurposed to for interactive or hands-on learning experiences. Through this arrangement, hitherto face-to-face class meetings become avenues for content-knowledge application, or concept mastery. Given that, flipped classes have attracted both excitement and skepticisms, this chapter attempts put things into perspective by streamlining the components, implementation, and the evidence of efficacy of flipped classes. The chapter examines concerns that flipped classes likely burden instructors and students especially those in rural and urban areas who may lack the resources needed to benefit from this strategy. The chapter further prescribes resources and procedures that could be useful to individuals interested in flipped classrooms.
Placing Technology in Learner-Centered Design through Blended Learning in Post-Secondary Education
Authors: Reid Doug , Ewing John
Published: August 2016

Two university education courses were converted from face-to-face delivery to a blended learning delivery model. Ideally the conversion took place to leverage new pedagogical understandings and new technologies to improve student learning. The redesign of the courses also came about for economic and scheduling reasons. The result of this conversion was the creation of two new blended learning courses that were designed to be learner centered, constructivist, and reflective. In theory, two different courses were created demonstrating the possibilities available when applying theoretical practices to course redesign. In practice, this allowed pre-service teachers to experience a pedagogically appropriate course that they can use as a model later in their own professional practice. It also emphasized the importance of giving learners control of their learning, their time and valuing their input into course design.
An Exploration of Learner-Centered Professional Development for Reluctant Math Teachers
Authors: Foster Ardyth , Lambert Joshua , Kim Jackie HeeYoung
Published: August 2016

In recent studies, researchers found that, while 90 percent of teachers reported participating in professional development, most of those teachers reported that it was not effective for improving their practice (Darling-Hammond et al., 2009; Garet, Porter, Desimone, Birman, & Yoon, 2001; Desimone, Porter, Garet, Yoon, & Birman, 2002; Corcoran & Foley, 2003). These findings indicate that the real issue is not that teachers are not provided with professional development, but that the typical modes of professional development are ineffective at changing teacher practices and/or student learning. Therefore, there is a need to explore new ways of conducting effective professional development for teachers. This study investigates a learner-centered model of professional development, which is designed to maximize the impact of teacher training on student learning.
Computer-Supported Collaborative Learning and Assessment
Authors: Gikandi Joyce W.
Published: August 2016

This chapter focuses on re-interpreting the findings of a recent study based on collaborative learning perspectives. The study utilized a case study design in which two online postgraduate courses were investigated as a collective case study. Online observations, analysis of the archived course content and interview transcripts were used as data collection techniques. The data from multiple sources were triangulated. Qualitative techniques were used in data analysis and descriptive statistics were integrated to extend the meaning of qualitative data. The findings of the study suggest that social interactivity is pivotal to facilitating meaningful learning in formal online education. The findings further illustrate that development of productive communities in continuing (in-service) education is a gradual process that evolves through four stages starting from community of interest to community of practice.
Learning in Organizations
Authors: Amar A.D. , Walsh Cathal
Published: August 2016

The authors find that learning in organizations that employ innovation and technology in their operations is fostered and incorporated in work environment for enhancing innovation while maintaining peak competiveness. It is divided across several segments, which include but are not limited to experimentation, risk tolerance, interaction with the external environment, dialogue, and decision-making. Conversely, this paper also examines several instances in which organizations failed to adopt a learning environment. Research illustrates that companies that fail continuously to improve fail because they can no longer competitively operate in today's global marketplace by holding onto the way work was once accomplished. Today's work environment is more demanding and less structured than in the past and, therefore, companies must adopt or they will become irrelevant. This paper also illustrates how learning actually occurs. Furthermore, the authors attempt to show the nascent relationship between learning and brain/mind principles at a cursory level. The paper also shows how the same basic principles utilized in educational learning can be applied to enhance corporate learning among adult learners.

Published: August 2016

This study was intended to assess the role of ICTs in utilization of teff technologies in Enebsie Sar Midir district. Simple random sampling procedure was used to select three kebeles and 136 households. Questionnaire and observation were used to collect data. Descriptive statistics like mean, percentage and frequency and univariate analysis such as t-test and chi-square tests and binary logistic regression model were used to analyze the data. Network interruption, language problem and usage difficulty were among the challenges not to use mobile phone. Interruption of electric power and information being not area specific were some challenges not to use radio and television for teff technologies. Construction of infrastructures, provision of adult education and trainings for farmers, introduction of Amharic language enabled mobile phones is very useful for increasing information and communication technologies use in teff technologies and hence increase teff production.
The Effects of Learning and Growth Perspective on Financial Performance in Private Universities
Authors: Al-Hosaini Fahmi Fadhl , Sofian Saudah
Published: August 2016

Many organisations are known to focus more on their financial gains to the detriments of their other roles that they are expected to discharge to their workforce and the communities. It has also been established from previous researches that financial performance would not be adequately valid with only performance measures unless others that are non-financial measures are incorporated, particularly with respect to those in the traditional BSC, such as is Learning and Growth Perspective (LGP). Yet, there are limited publications that examined the effects of LGP on organisational FP for Private Universities (PUs). In this paper, the effects of LGP on the Financial Performance of Yemen's PUs was investigated. A designed questionnaire based on Partial Least Square-Structural Equation Modeling (PLS-SEM) was carried out. The results showed that LGP has a positive and direct effect on the Financial Performance of the Yemen's PUs. This paper therefore will help in achieving the goals of Yemen's PUs of Yemen in order to enhance their organizational Financial Performance (FP).

Published: August 2016

Gamification is a new and upcoming trend that is predicted by many to further enhance the field of educational technology in the new millennium. The use of gamification has fared well in the corporate world and is gradually transcending into the educational arena. The usage of game elements such as points, badges and leader board can assist in keeping the students not only motivated but also engaged to the teaching and learning process in the school. As learning and assessment come hand in hand as a knowledge acquiring process in a classroom, therefore it should be identified whether or not gamification can be truly utilized in the form of a learning and assessment tool in the teaching and learning process. This paper will discuss about the repercussions of using gamification as a learning and assessment tool based on the review of several studies carried out in the field of gamification.

Authors: Thour Amit , Nagra Ramninder , Gosal Arunjeet , Sehrawat Tejasav , Das Subhash , Gupta Yashdeep
Published: August 2016

Background: Anxiety has been shown to be associated with poor outcomes in people with diabetes. However, there has been limited data, especially from India, which has specifically examined whether diabetes mellitus is associated with an increased likelihood of comorbid anxiety.

Aim: The aim was to estimate the prevalence of anxiety in patients with diabetes and to determine the association of anxiety with age, sex, and other related parameters.

Setting: Endocrine clinic, tertiary care hospital.

Design: Cross-sectional.

Materials and Methods: The study was cross-sectional carried out in endocrinology clinic of tertiary care hospital in North India. Cases were patients with type 2 diabetes mellitus above 30 years of age. Anxiety was assessed using the generalized anxiety disorders 7-item (GADs-7) scale. The relationship with a sociodemographic profile, duration of diabetes, hypertension, and microvascular complications was also analyzed.

Results: Seventy-three subjects (42.5% females) with mean age 50.8 ± 9.2 years were evaluated. The prevalence of anxiety was 34%. Severe anxiety (GAD-7 score ≥15) was present in three (4%) subjects, moderate anxiety (GAD-7 score ≥10) was present in six (8%) subjects, and mild anxiety was present in 16 (22%) of subjects. Anxiety increased with fasting plasma glucose, hypertension, was more in women, but the differences were not statistically significant.

Conclusions: Our study demonstrates a higher prevalence of anxiety in patients with type 2 diabetes. No factor was significantly associated with anxiety. Therefore, anxiety should be assessed in each and every patient, irrespective of other factors.
Fish consumption and omega-3-fatty acids in prevention of diet-related noncommunicable diseases
Authors: Jacob Jubbin
Published: August 2016

Diet-related noncommunicable diseases (DR-NCDs) which include obesity, hypertension, lipid disorders, type 2 diabetes mellitus, and cardiovascular (CV) disease are more common among people of South Asian descent because of genetic and other poorly understood factors. Indians are also one of the lowest consumers of fish and shellfish in the world despite being blessed with an extensive coastline. Consumption of fatty fish and fish oils supplementation has been demonstrated to improve blood pressure, lipid profiles, and CV outcomes. Data are still unclear if there is any impact on glucose intolerance with increased consumption of fatty fish or use of fish oils and omega-3-fatty acid (O3FA) supplements. The review focuses on the mechanisms of improvements with O3FAs on various aspects of DR-NCDs and reviews of current clinical data.
Fighting cancer through an informed society
Authors: Mehta Prashant , Bhajoni Pranjit , Mehta Swati
Published: August 2016

Social perceptions play an extremely important role in the lives of cancer patients and survivors. Society is a machinery which can dictate the behavioral pattern of a patient, the kind of treatment he/she seeks or believes in, and the treatment he/she finally takes. Proper education of the society, in general, with regard to various aspects of cancer and its treatment can make things easier for patients, their families and the treating physicians alike. False social beliefs create unsurmountable hurdles for both patients and their families. When families of cancer patients visit a doctor, very often they tend to describe the experience of one or more of their close or distant family members with cancer. They start reliving the same experience if it was bad, or they may develop a false sense of security about the curability if it was good. In both situations, it becomes difficult for them to understand that each cancer is different from the other, cancer being a heterogenous disease. Moreover, what the patients and their families hear from friends and their social support system about cancer in general makes them depressed, anxious, and vulnerable. The information they get from the Internet and print media is mostly unregulated and may present extreme views which compound their problems. In this review, we have analyzed some of the common perceptions and myths which we come across in clinical practice and have presented scientific data to refute or support these beliefs wherever suitable.

Authors: Gupta Neera , Dixit Tushar , K. Vikram
Published: August 2016

Make in India is a flagship campaign from the Government of India which is aimed at various sectors. Indian health-care system can take advantages by introducing digital technologies to health care. The possible uses of health information technology as a method to engage with people involving communicable and noncommunicable diseases (NCDs) are wide-ranging. Health information technology can support interventions for prevention, diagnosis, managing surveillance, disease monitoring, and treatment compliance of many conditions. Digital health can offer various technologies such as wearables that are tracked by various mobile or smartphone applications to facilitates patient engagement, self-monitoring, and implementing behavior changes in NCDs such as diabetes. By incorporating the interactive audiovisual items, the digital health tools can create greater interest and engage people from different geographies, age, gender, and culture. Currently, the common digital heath tech issues include hesitancy from doctors to adopt any new product or technology, difficulty in reaching and accessing the needy patients, cultural diversity in population, and inadequate infrastructure. The ethical issues of consent, data security, and privacy of patients need to be addressed as they are highly sensitive in nature.
Epidemiological study on cardiac emergencies in Indian states having GVK Emergency Management and Research Institute services
Authors: Ramana Rao G. , Rajanarsing Rao H. , Reddy G. , Prasad M.
Published: August 2016

Background: Emergency medical service (EMS) is critical for the healthcare system as it saves lives by providing care immediately. Rapid access to medical care after a major cardiovascular event decreases morbidity and mortality. GVK Emergency Management and Research Institute (GVK EMRI) is a pioneer in emergency management services operated as a public private partnership (PPP) with various state governments. GVK EMRI coordinates medical, fire, and police-related emergencies through a single toll-free number, 108, across 15 states and 2 union territories of India.

Material and Methods: This is a retrospective study of reported cases of cardiac emergencies in 2015 across 11 states with GVK EMRI services: Andhra Pradesh, Telangana, Assam, Goa, Gujarat, Karnataka, Madhya Pradesh, Meghalaya, Rajasthan, Tamil Nadu and Uttarakhand. Descriptive statistics using frequencies, proportions and means were calculated.

Results and Discussion: This study aimed to describe the epidemiology of cardiac emergencies presenting to GVK EMRI across 11 states in India in 2015. There were increased cases of cardiac emergencies reported by higher age group individual across all states. The mean age was reported between 43 years to 62 years across the states. In this study, men called EMS for cardiac emergencies more often than women, except in the state of Gujarat. A higher number of cardiac emergency cases were reported by individuals living below the poverty line in Andhra Pradesh, Telangana, Assam, and Goa. Often (82.8%) people called 108 greater than six hours of symptom onset. Variation in call volume per day was minimal between the days of the week. At 48 hours, there were 2,675 reported deaths (1.1%).

Conclusions: The current study stresses the scale and seriousness of the emerging challenge of cardiac emergencies, with particular emphasis on socioeconomic deprived groups in the operated states of GVK EMRI.
COBERTURA DE LIANAS NO DOSSEL FLORESTAL E SEUS EFEITOS SOBRE A REGENERAÇÃO DE ESPÉCIES ARBÓREAS
Authors: Silva Marcele Almeida da , Rodrigues Mariane Martins , Righi Ciro Abbud
Published: August 2016

A regeneração natural é um bom indicador da capacidade de perpetuação das espécies arbóreas e da manutenção da biodiversidade em fragmentos florestais. O estado de conservação desses remanescentes está diretamente relacionado ao seu tamanho, tipo de vizinhança e grau de perturbação. A abundância de lianas vem sendo apontada como um indicador de degradação afetando diretamente a regeneração natural. Desse modo, é importante a avaliação da presença e cobertura de lianas no dossel das árvores e verificar sua influência na regeneração natural. Neste estudo, avaliou-se a participação das lianas na cobertura do dossel de uma Floresta Estacional Semidecidual inserida em uma matriz de pastagem, procurando relacioná-la com a regeneração natural. Para avaliar essa regeneração foram instalados e avaliados doze transectos radiais perpendiculares à borda do fragmento. Observou-se que as maiores densidades de regeneração foram encontradas nas áreas em que a cobertura do dossel estava acima de 80%, independentemente de sua composição (lianas ou árvores), indicando que a cobertura por lianas também contribui positivamente para o desenvolvimento dos regenerantes.

A simple equation for the melt elevation feedback of ice sheets
Authors: Levermann Anders , Winkelmann Ricarda
Published: August 2016

Abstract. In recent decades, the Greenland Ice Sheet has been losing mass and has thereby contributed to global sea-level rise. The rate of ice loss is highly relevant for coastal protection worldwide. The ice loss is likely to increase under future warming. Beyond a critical temperature threshold, a meltdown of the Greenland Ice Sheet is induced by the self-enforcing feedback between its lowering surface elevation and its increasing surface mass loss: the more ice that is lost, the lower the ice surface and the warmer the surface air temperature, which fosters further melting and ice loss. The computation of this rate so far relies on complex numerical models which are the appropriate tools for capturing the complexity of the problem. By contrast we aim here at gaining a conceptual understanding by deriving a purposefully simple equation for the self-enforcing feedback which is then used to estimate the melt time for different levels of warming using three observable characteristics of the ice sheet itself and its surroundings. The analysis is purely conceptual in nature. It is missing important processes like ice dynamics for it to be useful for applications to sea-level rise on centennial timescales, but if the volume loss is dominated by the feedback, the resulting logarithmic equation unifies existing numerical simulations and shows that the melt time depends strongly on the level of warming with a critical slowdown near the threshold: the median time to lose 10 % of the present-day ice volume varies between about 3500 years for a temperature level of 0.5 °C above the threshold and 500 years for 5 °C. Unless future observations show a significantly higher melting sensitivity than currently observed, a complete meltdown is unlikely within the next 2000 years without significant ice-dynamical contributions.
The Debate between Grunbaum and Ricoeur: The Hermeneutic Conception of Psychoanalysis and the Drive for Scientific Legitimacy
Authors: Trotter Gregory A.
Published: August 2016

Paul Ricœur’s hermeneutic approach to psychoanalysis stresses the interpretation of meanings revealed via the narratives woven through the discursive exchanges between analyst and analysand. Despite the tremendous influence Ricœur’s interpretation enjoyed both in philosophy and in psychoanalysis, his approach has been subject to severe criticism by Adolf Grünbaum who argues that Freud modeled psychoanalysis on the natural sciences, and therefore it should be judged according to natural scientific standards. I argue that Grünbaum incorrectly downplays the importance of speech and language in psychoanalytic theory and practice, and moreover, that Ricœur’s approach offers important insights that deserve to be redeployed today.
Adolf Grünbaum critique de Ricoeur
Authors: Lacour Philippe
Published: August 2016

Dans cet article, je cherche à reconstituer le débat esquissé entre Ricœur et Grünbaum touchant l’épistémologie de la psychanalyse freudienne. Le débat est esquissé plutôt qu’effectif, car l’échange est asymétrique (Grünbaum a lu et analysé Ricœur, mais la réciproque est plus douteuse). Pour mieux arbitrer ce débat virtuel, l’article présente d’abord l’originalité de la position de Ricœur touchant les concepts de motivation (mixte raison-cause) et de causalité (téléologique) puis, à cette aune, répond aux autres critiques de Grünbaum dans leur détail: la survalorisation de la relation clinique et du langage, la spécificité ontologique de la réalité psychique, l’originalité narrative de l’explication psychanalytique et le statut du symbole. L’article conclut à un triple apport de ce débat virtuel, concernant la spécificité de l’herméneutique psychanalytique, le rôle du transfert et, enfin, la nature “casuistique” de la connaissance psychanalytique.

ENERGY GENERATION FROM MUNICIPAL SOLID WASTE AND THE CURRENT SCENARIO OF BIOGAS RECOVERY IN BRAZIL
Authors: Schirmer Waldir Nagel , Crovador Maria Isabel Coltro
Published: August 2016

The landfill is a method of treatment and final disposal of municipal solid waste (MSW) widely employed all over the world, mainly in developing countries. The biogas released from landfills raises environmental concerns, as it contributes to the greenhouse effect, due to its high content of methane and carbon dioxide, and in relation to the potential damage to health caused to the surrounding populations of these areas. However, biogas has a great energy potential, representing economic and environmental advantages, making the waste disposal in landfills more sustainable in relation to these economic and environmental aspects. In Brazil, few landfills are technically prepared in recovering energy from biogas, which may be encouraged by the new Solid Waste National Policy, which aims to fit the landfills to the technical criteria of engineering, as well as to provide appropriate instructions on the waste management throughout its life cycle. The present review deals with the process of biogas generation based on municipal solid waste and some techniques that provide quantitative data on the biogas emission, and also the current scenario in Brazil related to the energy recovery from such source of bioenergy and its future potentialities.
EFEITO DA CONCENTRAÇÃO NA DILATAÇÃO VOLUMÉTRICA DO SUCO DE AMORA-PRETA
Authors: Canciam César Augusto
Published: August 2016

O estudo da dilatação térmica em líquidos é feito somente em relação à dilatação volumétrica, sendo importante o conhecimento do coeficiente de expansão térmica. O presente trabalho teve por objetivo verificar o efeito da concentração de sólidos totais nos valores do coeficiente de expansão térmica do suco de amora-preta. Para tanto, através da análise de regressão linear da densidade de cada suco em função da temperatura, foi possível predizer os valores para o coeficiente de expansão térmica. Estes dados foram estimados de outro trabalho. Os valores encontrados para o coeficiente de expansão térmica variaram de 4,0420x10-4ºC-1 (58,4ºBrix) a 5,1890x10-4ºC-1 (9,4ºBrix). O intervalo de temperatura considerado foi de 10 a 70ºC. Constatou-se que na medida em que se aumentou a concentração de sólidos totais, diminuiu-se o valor do coeficiente de expansão térmica. Provavelmente, isto esteja associado ao tipo de ligação intermolecular formado entre a água e os compostos fenólicos presentes no suco de amora-preta. Na literatura não foram encontrados valores experimentais do coeficiente de expansão térmica para o suco de amora-preta, o que dificultou a análise.
ULTRAFILTRAÇÃO DE EFLUENTE MODELO E EFLUENTE INDUSTRIAL DE LATICÍNIOS
Authors: Brião Vandré Barbosa , Tavares Célia Regina Granhen , Favaretto Danúbia Paula Cadore , Hemkemeier Marcelo
Published: August 2016

A preocupação com a poluição hídrica tem levado a busca de soluções diferenciadas para o tratamento de efluentes da indústria de laticínios, os quais são gerados em grandes volumes e com alta carga poluidora. O trabalho objetivou aplicar duas diferentes membranas de ultrafiltração para o tratamento de duas amostras de efluentes de laticínios: uma amostra modelo, produzida pela diluição de leite em pé em água; e outra amostra industrial. Avaliou-se a rejeição dos compostos presentes no efluente pelas membranas e o fluxo permeado, comparando o comportamento das membranas para os dois efluentes. Os resultados demonstraram que o efluente modelo apresentou rejeições semelhantes ao efluente industrial para ambas as membranas, removendo DQO acima de 70%, cerca de 97% das proteínas e gorduras acima de 90%. A membrana tubular de PVDF, com diâmetro de corte de 30-80 kDa apresentou um fluxo superior à membrana espiral de PES (diâmetro de corte de 5 kDa) para o efluente modelo e industrial, embora o fluxo permeado com o efluente industrial foi 50% inferior ao efluente modelo, devido maior concentração presença de sólidos suspensos. A ultrafiltração demonstrou ser uma promissora alternativa para o tratamento de efluentes de laticínios.
CONDUTIVIDADE HIDRÁULICA DE MISTURAS SOLO-CIMENTO COMPACTADAS SUBMETIDAS À AÇÃO DE LIXIVIADOS ÁCIDOS
Authors: Tímbola Rafael De Souza , Prietto Pedro Domingues Marques , Nascentes Rejane , Korf Eduardo Pavan
Published: August 2016

O descarte inadequado de resíduos sólidos industriais e de mineração tem causado ao longo dos anos, contaminação do solo e das águas subterrâneas, principalmente pelo vazamento de lixiviados ácidos. Neste contexto, o presente trabalho avaliou o comportamento hidráulico de um solo residual argiloso compactado, com e sem adição de cimento Portland (0% e 2%), para utilização em barreiras impermeáveis (liners) de fundo em aterros de resíduos sólidos industriais e de mineração, quando submetidos à percolação de soluções ácidas. Um equipamento de coluna modificado, de parede rígida, foi utilizado na determinação da condutividade hidráulica. Os corpos de prova, moldados com duas energias de compactação diferentes, Proctor normal e Proctor modificado, foram percolados inicialmente com água destilada, até o regime de fluxo permanente, e posteriormente com uma solução de ácido sulfúrico até um limite de 15 volumes de vazios. A solução ácida utilizada foi preparada com uma concentração volumétrica de 2%, com o intuito de simular uma drenagem ácida de mineração. A partir dos resultados obtidos, pode-se observar que o aumento do peso específico de compactação e uma maior porcentagem de cimento favorecem a redução da condutividade hidráulica, tanto na fase de percolação com água destilada como durante a percolação ácida.
DILATAÇÃO VOLUMÉTRICA DE SOLUÇÕES AQUOSAS DE FENILHIDRAZINA
Authors: Canciam César Augusto
Published: August 2016

A dilatação volumétrica é variável e tende a manter uma relação direta com a composição química. Em geral, materiais em que as ligações químicas são fortes, apresentam baixos coeficientes de dilatação volumétrica. O objetivo deste trabalho foi estimar o coeficiente de dilatação volumétrica de soluções aquosas de fenilhidrazina com frações molares diferentes, a partir de dados experimentais da massa específica em função da temperatura. Esses dados estão disponíveis na literatura. Em um intervalo de 293 a 353 K, os valores do coeficiente de dilatação volumétrica variaram de 3,55x10-4 K-1 (solução com fração molar 0,10) a 7,66x10-4 K-1 (solução com fração molar 0,50). Constatou-se que o coeficiente de dilatação volumétrica aumenta entre as soluções com frações molares de 0,10 a 0,50. Para soluções com frações maiores que 0,50 até 0,90, o coeficiente de dilatação volumétrica diminui. Provavelmente, esse comportamento esteja associado ao tipo de ligação intermolecular formado entre a água e a fenilhidrazina.

Revisão integrativa com o objetivo de identificar as principais temáticas abordadas em ambiente hospitalar para a segurança do paciente. A busca ocorreu em três bases de dados eletrônicas, abrangendo o período de 2009 a 2015, com os descritores: “Segurança do Paciente”, “Controle de risco” e “Hospitalização”. A amostra do estudo constituiu-se de 34 artigos. Houve aumento significativo no número de publicações sobre a temática em 2013, mais de 100% comparando-se ao ano de 2009. Dos estudos, 22,22% tratavam sobre eventos adversos e 18,52% sobre erros na administração de medicamentos. Dentre as medidas preventivas, 37,93% destacam a educação continuada e 13,79% a lavagem das mãos e a identificação correta do paciente. A opção estratégica pela segurança tem sido incluída nas agendas das instituições, organizações e sistemas de saúde como prioridade. Logo, sugere-se ampliar o foco da pesquisa para a melhoria na qualidade do cuidado.

Este artigo parte da ideia de que a gestão de serviços de Tecnologia da Informação (TI) em uma organização educacional pode melhorar a qualidade desses serviços e colocá-los em consonância com os objetivos da organização, portanto, avaliar torna-se relevante. Diante disso, o objetivo deste artigo consistiu em apresentar resultados de estudo de um caso exploratório, realizado junto a alunos matriculados no curso de Administração de uma Instituição de Ensino Superior, em os discentes avaliaram disciplina ofertada em caráter semipresencial. Os dados foram obtidos mediante a aplicação de questionário e observação da prestação de serviços, discorrendo-se sobre os achados. Como resultados, foram levantados indicadores de avaliação do Sistema de EaD e identificados problemas, segundo a percepção desses alunos. A partir dos resultados destaca-se que a Universidade desconhece a metodologia ITIL® e que seria fundamental que fosse implantada uma estratégia de serviço (fase inicial da ITIL®), como ponto de partida para a melhoria contínua do serviço e da infra-estrutura da Universidade.
Como o Uso de Ferramentas de Gerenciamento de Projetos é Ensinado em Cursos Superiores de Computação: Um Panorama das Instituições de Ensino Brasileiras
Authors: Gonçalves Rafael Queiroz , Wangenheim Christiane Gresse von
Published: August 2016

Devido à complexidade dos projetos de software contemporâneos, o Gerenciamento de Projetos (GP) é impraticável sem o apoio de ferramentas de software. Assim, o uso destas ferramentas também precisa ser abordado no ensino de GP em cursos superiores de computação. Mesmo existindo bastante literatura sobre o ensino de GP em geral – principalmente do ensino de conceitos e métodos, não se encontra muita informação sobre como ensinar o uso destas ferramentas. Com o propósito de compreender como atualmente esta competência é ensinada, a presente pesquisa busca caracterizar o ensino das ferramentas de GP nos cursos superiores de computação em instituições de ensino brasileiras. Para isto, foi conduzido um survey com objetivo de identificar: (a) quais ferramentas de gerenciamento de projetos são ensinadas; (b) como são definidas as unidades instrucionais; e (c) como são avaliadas. Foram convidados 590 professores de disciplinas de GP e engenharia de software no Brasil, e obtidas 92 respostas. Os dados coletados são sintetizados e apresentados, mostrando um panorama da situação atual nas instituições de ensino brasileiras. Os resultados podem ser aproveitados por professores da engenharia de software em relação às suas disciplinas, e também por pesquisadores, apontando oportunidades para melhorar o ensino deste conteúdo de forma mais eficaz e eficiente.

A comunidade de informática na educação do Brasil, tem entre seus principais eventos o Simpósio Brasileiro de Informática na Educação (SBIE), o Workshop de Informática na Escola (WIE) e, nos últimos anos, o Congresso Brasileiro de Informática na Educação (CBIE) que atualmente reúne estes dois eventos. Além disso, a revista Brasileira de Informática na Educação (RBIE) tem reunido contribuições da comunidade científica na área ao longo dos anos. Ao analisar essas fontes na Internet, observamos que  todos os trabalhos publicados são de livre acesso; no entanto, é difícil construir uma visão geral dos focos de cada uma destas fontes, identificar os autores mais ativos, e determinar a quantidade e o tamanho de suas  redes de cooperação. Estas informações podem ser usadas, por exemplo, para identificar os temas que estão ganhando ou perdendo relevância em cada uma destas fontes ao longo do tempo,  o grau de cooperação da comunidade e linhas gerais de seu perfil.  Para uma visão geral dos temas presentes nas contribuições, e como ponto de partida de uma análise mais aprofundada, este artigo utiliza o poder expressivo de tagclouds sobre os títulos dos trabalhos, assim como sobre seus resumos. Os resultados permitiram construir um roteiro dentro do campo, que pode informar os pesquisadores e profissionais que estão iniciando  trabalho em áreas afins e os especialistas que querem aprofundar conhecimento sobre o tema.

O objetivo do trabalho foi avaliar a penetração e a retenção do preservativo CCB em moirões de Eucalyptus viminalis Lab. e de bracatinga (Mimosa scabrella Benth.), quando submetidos ao método de substituição da seiva. Os moirões foram expostos às concentrações de 2; 3,5 e 5% de ingredientes ativos do produto "Osmose CCB", durante 2; 5 e 8 dias. Foram analisadas as penetrações em seis posições nas peças e as retenções em três posições nos discos retirados na posição correspondente a linha de afloramento em moirões instalados. O aumento da concentração e do tempo de tratamento proporcionou ganhos significativos na penetração e na retenção do CCB nos moirões. Nas condições em que o trabalho foi conduzido o eucalipto apresentou uma melhor resposta ao tratamento.
