Open educational resources (OER) are digitised material freely available to the students and self learners. Many institutions had initiated in incorporating these OERs in their higher educational system, to improve the quality of teaching and learning. These resources promotes individualised study, collaborative learning. If they are coupled with Learning Objects of Learning Management System (LMS), they can lead to opportunities for further pedagogical innovation. It has become increasingly important for educational institutions to support these resources, in a planned and systematic manner. Adapt, assemble and conceptualise existing OERs to respond to diverse learning needs of students and support a variety of learning approaches for a given learning goal is a challenge. In this work, convergence of OERs with Learning Objects is done through metadata using classification techniques. Localisation of these high quality learning materials with the learning content of LMS, delivered as a single instructional unit may help in greater knowledge delivery and this can satisfy the learning needs of diverse student. 相似文献

Ayurveda is a traditional form of medicine used by majority of the Indians. Here we report three cases of lead toxicity, following
intake of Ayurvedic medicines. Three patients presented with blood lead levels (BLLs) of 122.4, 115 and 42.8 μg/dl respectively
at the time of hospitalization. The first case was chelated with D- penicillamine, the second with calcium disodium ethylene
diamino tetra acetate (EDTA) and the third with environmental intervention and education. Associated Ayurvedic products were
collected from patients and analyzed for metallic concentration. Cessation of Ayurvedic medication along with chelation, nutritional
intervention and education, reduced the BLL to 27.4 μg/dl in the first case after 1 year, 21.1 μg/dl after 9 months in the
second and 18.2 μg/dl after 6 months in the third case. 相似文献

An important research area in education and technology is how the learners use e-learning. By exploring the various factors and relationships between them, we can get an insight into the learners’ behaviors for delivering tailored e-content required by them. Although many tools exist to record detailed navigational activities, they don’t explore the learners’ usage patterns for an adaptive e-learning site. The previous web log data analyses, done so far, have been very limited in their scope as they lack detailed empirical results on the learning technology usage. This paper discusses the detailed results of a case study of web data mining in a specific e-learning application. The main objective of this study is to conduct research on usability and effectiveness of the e-content by analyzing the web log. For this, a suitable data set was retrieved from raw web log records, to which various web mining & statistical techniques could be applied. We have evaluated different features of e-content that can lead to better learning outcomes for the learners, by understanding their navigational behaviors, their interaction with system and their area of interest. We found, for example, what sequence of topics were the most liked and the least liked by the learners; we also found that these patterns, lead us to hypothesize, the correlation and regression analysis between the average time, test score and total attempts. 相似文献

Awareness about the toxic effects of non-essential metals is still lacking in developing countries. Lead is one among them,
which ranks second in the Agency for Toxic Substances and Disease Registry’ s top 20 lists of toxic metals. Some of the herbal
medicines prepared from certain roots and leaves are known to contain this toxic metal at alarming levels. We have a case
of a person who suffered from the toxic effects of lead such as vomiting and colicky abdominal pain after consuming a herbal
remedy for Jaundice treatment. This went unrecognized initially because of the presence of multiple problems like Malaria
and Renal calculi. Lead poisoning as causative factor for anemia, vomiting and colic were confirmed only when blood lead concentration
was estimated. A combination of chelation therapy and nutritional supplementation was found to be useful in reducing the body
lead burden. 相似文献

ABSTRACTIn a networked society, humans are connected through mobile devices to always-on networks, and these technologies merge with us in new ways. In this environment, studying human-networked interactions involves an expanded type of usability. In this article, we argue that a key component of usability is how humans connect and disconnect from these networks. For this reason, the authors advocate studying how users connect and disconnect between online and offline contexts in their everyday life. Such an effort involves questioning our assumptions about the role of connection in usability and introduces methodological issues in studying these processes. These shifts require our research to be more multidisciplinary and more methodologically demanding, with major implications for the portability and durability of technical communication research. 相似文献

In the first decade of this century, India became one of the world’s fastest growing large economies, and began to face serious skill-related shortages of workers. Its TVET system has not responded adequately to the growth in demand for semi-skilled and skilled workers. This article describes six sets of reforms that India’s educational planners and policy-makers must put into place if these shortages are not to constrain India’s ability to benefit from the demographic dividend. 相似文献

This article introduces a simple mapping tool called Grassroots, a software product from a longitudinal study examining the use of information communication technologies and knowledge work in communities. Grassroots is an asset-based mapping tool made possible by the Web 2.0 movement, a movement which allows for the creation of more adaptable interfaces by making data and underlying database structures more openly available via syndication and open source software. This article forwards three arguments. First is an argument about the nature of the knowledge work of everyday life, or an argument about the complex technological and rhetorical tasks necessary to solve commonplace problems through writing. Second is an argument about specific technologies and genres of community-based knowledge work, about why making maps is such an essential genre, and about why making asset maps is potentially transformative. Third is an argument about the making of Grassroots itself; a statement about how we should best express, test, and verify our theories about writing and knowledge work. 相似文献

Helminthic infections lead to the release of various molecules which play an important role in modulation of the host immune system. Such filarial proteins with immunomodulatory potential can be used for therapeutic purpose in inflammatory and immune mediated diseases. In the present study, we have explored the prophylactic effect of filarial SXP–RAL family protein of Wuchereria bancrofti i.e. rWbL2 protein in DSS induced inflammatory ulcerative colitis in a mouse model. Prior treatment of rWbL2, followed by induction of colitis, showed significantly reduced disease severity as indicated by the decreased disease manifestations and improved macroscopic and microscopic inflammation. This preventive effect was found to be associated with increased release of anti-inflammatory cytokine IL-10 and decreased release of proinflammatory cytokines IFN-γ, TNF-α, IL-6 and IL-17 by the splenocytes of treated mice. From this study, it can be envisaged that pretreatment with filarial protein, rWbL2, can prevent the establishment of ulcerative colitis in BALB/c mice. The underlying immunological mechanism may involve the up-regulation of Th2 immune response with down-regulation of Th1 response. 相似文献
