The elderly represent a population group that requires a specific and integral\napproach that promotes its wellbeing and health. There are contextual factors\nexperience during this life stage, such as the generation of diseases, which can\ninfluence negatively central aspects of life. One of the constructs that could be\naffected by these factors is the Quality of Life (QOL). The interaction between\nthe contextual variables and QOL is mediated by the Coping Strategies (CS)\nthat the individual applies to cope with the environmental challenges. The aim\nof this research was to analyze the differences in Quality of Life levels of the\nelderly, controlling for the type of Coping Strategies implemented. A transversal\nstudy was conducted, including a sample of 100 senior adults of the\nMetropolitan District of Quito, Ecuador. The participants signed a inform\nconsent form and answered the Inventario de Estrategias de Afrontamiento\n(Survey of Coping Strategies) and the FUMAT Scale for the evaluation of\nQOL. The mean age was 74.6 years (SD = 5.5), being 64% women. We observed\npercentages lower than 50% in all QOL dimensions, being the material\nwellbeing, the subscale with lower scores. The CS more frequently reported\nwere the problem resolution, the desiderative thinking and the self-criticism.\nThe participants that referred to use the emotional expression as a coping\nstrategy presented higher levels of QOL. The Quality of Life in the elderly is\ninfluenced by contextual factors, being necessary to provide them with strategies\nthat can be used to cope with the life challenges in a more effective and\nadaptive way....
Background: Survey quality, in particular sampling, coverage, and issues of\nrepresentativity, are important for valid and reliable conclusions from epidemiological\ndata. Dental anxiety (DA) still challenges dental clinicians since it\nis synonymous with care avoidance. Accurate estimates of DA are important\nfor public health. Aims were to 1) assess demographic representativity (age/\ngender) of a 2013-14 web survey and a 1992-93 telephone survey about DA in\nDanish adults aged 16 - 80 yr using government statistics; 2) assess DA frequency\nand characteristics from web survey data (N = 701); and 3) compare\nweb results with 1993 results. Method: Dental Anxiety Scale (DAS) measured\nDA, while other items revealed gender, age, education, dentist avoidance, and\nthree types of negative dentist behaviors. Analyses used frequencies, Chisquare,\nodds ratios (OR) and ANOVAs. Results: Samples from 1992-3 and\n2013-14 were not significantly different by demographics or government statistics,\nwith the exception of low numbers in ages 16 - 19 yr for both surveys.\nAges 20 - 29 yr and 30 - 39 yr were slightly overrepresented in telephone data,\nwhile ages 50 - 59 yo were in web data. Mean DAS scores were 7.5 for both\n1992-3 and 2013-14. Extreme DA (DAS 20-15) increased from 4.2% to 5.3%,\nwhile high DA (DAS � 13) increased from 6% to 9.5%. Main 2013-14 associations\nwith DAS � 15 were women (OR = 4.7), avoiding dentists (OR = 11.4)\nand negative dentist behaviors (OR = 4.2 - 6.7) similar to 1992-3 data. Conclusion:\nWeb survey results from this convenience sample were demographically\nrepresentative for adults 20 - 80 yo and showed small changes in DA after\n20 years. Future strategies regarding survey of teenagers require special attention....
Comparing two software development teams working on similar projects in a\nlarge software company, this research study focuses on the question as to\nwhether the implementation of ethical tools in the software development\nprocess serves as a quality driver. Is ethics a quality driver in Agile development\nprocesses? The findings of the present study indicate that there is a significant\ncorrelation between the inclusion of ethical tools in the process of\nplanning in Agile methodologies and the achievement of improved performance\nin three quality parameters: schedule, product functionality and cost.\nTheoretically, the connection between ethics and quality is important. Practically,\nthis study�s findings show that the inclusion of ethical tools in Agile\nsoftware projects can improve the quality of a project....
Crossed cubes network is a kind of interconnection structure as a basis for\ndistributed memory parallel computer architecture. Reliability takes an important\nrole in fault tolerant computing on multiprocessor systems. Connectivity\nis a vital metric to explore fault tolerance and reliability of network\nstructure based on a graph model. Let G = (V, E) be a connected graph. The\nk-conditional edge connectivity �Žk (G) is the cardinality of the minimum\nedge cuts F , if any, whose deletion disconnects G and each component of\nG - F has property of minimum degree �´ â�¥ k . The k -conditional connectivity\nKk (G) can be defined similarly. In this paper, we determine the kconditional\n(edge) connectivity of crossed cubes CQn for small k. And we\nalso prove other properties of CQn....
Global Digital Elevation Models (DEMs) have been utilized in various geomatics\nactivities worldwide. Recently, there exist several available DEMs vary significantly\nin terms of spatial resolution and release dates. This paper examines\nthe reliability of eight recent global DEMs, namely the EarthEnv-D90, SRTM\n1, SRTM 3, ASTER, GMTED2010, GLOBE, GTOPO30, and AW3D30, in two\nstudy areas in Egypt and Saudi Arabia representing different topography patterns.\nKnown ground control points with measured accurate coordinates and\nprecise elevations have been utilized in evaluating the performance of those\nDEMs. It has been concluded that such a judgment procedure should not be\ncarried based on a single statistical measure. First, five statistical measures,\nspecifically the range, standard deviation, correlation, kurtosis, and skewness,\nhave been evaluated separately for each DEM�s errors. Then, a new reliability\nindex is introduced based on the weighted average concept. The accomplished\nresults show that global DEMs perform differently in different topography patterns.\nIt has been concluded that the EarthEnv-D90 and SRTM1 models attain\nhigh reliability indexes in the Nile delta region that represents a flat topography,\nwhile the GMTED2010 and EarthEnv-DEM90 models came in the first\nplaces for the second study area, Makkah, which represents mountainous topography....
