Evaluating a Personal Learning Environment for Digital Storytelling

The evaluation of flexible and personal learning environments is extremely challenging. It should not be limited to the assessment of products, but should address the quality of educative experience with close monitoring. The evaluation of a PLE using digital storytelling is even more complicated, due to the unpredictability of the usage scenarios. This paper presents an evaluation methodology for PLEs using digital storytelling, using a participatory design approach. The results from an open validation trial indicate that this methodology is able to incorporate all necessary factors and that the selected evaluation tools are appropriate for addressing the quality of educative experience

The analyse of the antioxidant effect of natural peloidotherapy in aging process

Medical research has developed remarkably in recent years, including the involvement of the glutathione peroxidase (GPx) family of enzymes in the course of human aging, with numerous clinical studies published in the literature reporting this particular fact. Thus, mud therapy and its effect on biological aging have been represented in papers that have been published to date. Papers published in the literature analyzing GPx vari-ation during sapropelic mud therapy suggest the beneficial effect of this family of en-zymes in diseases with an important inflammatory component, mainly monitored in patients with osteoarthritis. This study investigated the effects of sapropelic mud treat-ment on GPx values in patients receiving treatment with sapropelic mud at the Balneal and Rehabilitation Sanatorium of Techirghiol, Romania. We included 52 patients, split into two groups, who received treatment with cold mud baths and warm mud baths. Values close to statistical significance were found in patients who received treatment with cold mud baths in terms of mean GPx values at the four-time points studied. Fur-ther studies evaluating GPx in patients receiving sapropelic mud treatment are needed

Green education using open educational resources (OER): setting up a green OER repository

A wealth of open educational resources (OER) focused on green topics is currently available through a variety of sources, including learning portals, digital repositories and web sites. However, in most cases these resources are not easily accessible and retrievable, while additional issues further complicate this issue. This paper presents an overview of a number of portals hosting OER, as well as a number of “green” thematic portals that provide access to green OER. It also discusses the case of a new collection that aims to support and populate existing green collections and learning portals respectively, providing information on aspects such as quality assurance/collection and curation policies, workflow and tools for both the content and metadata records that apply to the collection. Two case studies of the integration of this new collection to existing learning portals are also presented.The work presented in this paper has been funded with support by the European Commission, and more specifically the project “Open Discovery Space: A socially-powered and multilingual open learning infrastructure to boost the adoption of eLearning resources” of the CIP-ICT-PSP Programme (Project Number 297229)

The Influence of Diet and Physical Activity on Oxidative Stress in Romanian Females with Osteoarthritis

Osteoarthritis (OA) is the most prevalent chronic joint disease, increases in prevalence with age, and affects most individuals over 65. The present study aimed to assess the oxidative status in relation to diet and physical activity in patients with OA. We used a cross-sectional study applied to 98 females with OA. Blood samples were collected to determine oxidative stress markers: malonyl dialdehyde (MDA), reduced glutathione (GSH), oxidized glutathione (GSSG), and GSH/GSSG. Diet was estimated with a standardized food frequency questionnaire. We used the International Physical Activity Questionnaire (IPAQ) to assess the females’ physical activity. Multiple regression analyses were executed to determine the association between the oxidative markers and the intake of vegetables and fruit. The study showed that most patients were overweight or obese (88.8%). The level of physical activity was above the recommended level for adults, mainly based on household activities. The intake of vegetables and fruit was low. The MDA marker was inversely, statistically significantly associated with the consumption of vegetables (p < 0.05). Public health policies must address modifiable risk factors to reduce energy intake and obesity and increase the intake of vegetables and fruit. Higher consumption of vegetables and fruit may provide natural antioxidants that can balance oxidative compounds
