A Systematic Review of Data Exchange Formats in Advanced Interaction Environments
Celso A. S. Santos,Estêvão B. Saleme,Juliana C. S. de Andrade 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.5
The advent of advanced user interface devices has raised the interest of industry and academia in finding new modes of Human-Computer Interaction. Advanced interfaces employ gesture recognition, as well as motion and voice capturing to enable humans to interact naturally with interactive environments without utilizing any of the traditional devices like mice, joysticks or keyboards. Many approaches have been developed using a large variety of sensors to capture human interaction information and then provide further processing and recognition of the acquired information. However, the majority of these approaches usually focus on the actual implementation of the various stages that comprise an advanced interaction environment. Thus, the need for defining common data formats for improving integration and reutilization of these solutions are typically not addressed. On the other hand, this study aims at surveying existing research on integrating devices into interactive environments, at different interoperability levels and in data formats, identifying techniques and patterns of conveying information from the real world to the virtual world, in order to synthesize results, organize applicable documents by similarities and identify future research needs.

Antidiarrheal Activity of Campomanesia xanthocarpa Fruit
Tatiana M. Souza-Moreira,Luiz Estêvão Salvagnini,Emerson Santos,Viviana Y.A. Silva,Raquel R.D. Moreira,Hérida R.N. Salgado,Rosemeire C.L.R. Pietro 한국식품영양과학회 2011 Journal of medicinal food Vol.14 No.5
The growing list of drug-resistant microorganisms and the persistence of deaths due to diarrhea are compelling reasons to study plants in search of new therapeutic agents. The chemical constitution and popular use of the edible fruits of Campomanesia xanthocarpa O. Berg motivated this study to assess the antimicrobial and antidiarrheal properties of the fruits. An extract in 70% ethanol was prepared, and its antimicrobial activity was tested against several strains of bacteria by the agar diffusion and microdilution methods. Antidiarrheal activity was analyzed by testing intestinal motility in an animal model. Preliminary phytochemical study indicated the presence of flavonoids, saponins, and tannins in the hydroalcoholic extract. Antimicrobial activity was significant, but the minimum inhibitory concentration proved to be higher than the maximum extract concentration tested. The extract did not show significant activity for intestinal motility. Although this fruit extract did not show great results as an antimicrobial or antidiarrheal agent, the study contributes to the search for new plant agents and could be referred to as a research protocol by investigators in this area.

Patients with chronic renal failure, many of which treated with hemodialysis, present a high prevalence of impaired muscle strength which suggest that muscle mass parameters may be used as markers for changes in muscle in these patients. Measurement of handgrip strength (HGS) is a common, simple, and quick measure of muscle function an indicator of overall muscle strength which has been associated with physical activity and several anthropometric traits. Intercellular adhesion molecule-1 (ICAM-1) and insulin-like growth factor-1 (IGF-1) are biochemical markers associated with inflammatory processes which are a common consequence of dialysis. Additionally, hemodialysis patients frequently present signs of malnutrition and depression. This cross-sectional study aimed to evaluate if muscle and biochemical markers could be used to predict the risk of depression in hemodialysis patients. Several anthropometric parameters, nutrient intake, depression state and the serum levels of ICAM-1 and IGF-1 were determined and Pearson’s correlation coefficient and/or Spearman’s correlation coefficient were used to test the correlation between them. Our results do not show a correlation between HGF, IGF-1 and ICAM-1 with the depression status of the patients, but mid-arm muscle circumference (MAMC) was statistically and positively correlated with depression. Additionally, ICAM-1 levels were negatively correlated with HGS, MAMC, and IGF-1. Overall, the results of the present study suggest that HGS may be used as an indicator of cardiovascular diseases and MAMC may be a good predictor of the level of depression in hemodialysis patients, although further studies are required.
