Cloud computing is an emerging technology in the world of computing. It provides a convenient virtual environment for on-demand access to different type of services and computing resources such as applications, networks and storage space in an efficient way. The virtual environment is a massive compound structure in terms of accessibility that made easy in a compact way and familiar of functional components. The complexity in virtual environment generates several issues related to data storage, data security, authorization and authentication in cloud computing. With the size of the data, it becomes difficult to the cloud user to store large amounts of information in the remote cloud servers due to high computational cost, insecurity and costs high per hour proportional to the volume of information. In this paper, we propose compressed hash based encrypted model for the virtual environment. The aim of this paper is to store huge amount of data in the cloud environment in the form of compressed and encrypted data in a secure way.

Introduction/Aim. Epidemiological investigation of risk factors for acute myocardial infarction (AMI) does not work is to primarily find new risk factors, as they have already identified a few hundred, but to investigate the representation in that area, in order to take appropriate preventive measures that could stop the further growth of diseased and dying from this disease. The aim of this study was to investigate the unhealthy nutrition as risk factor for acute myocardial infarction in examined population. Methods. A case-control study with 155 patients with a first myocardial infarction and 155 controls, matched with respect to sex and age (± 2 years) from the city of Niš, was used. Data was obtained throught the epidemiological questionnaire. Results. Number of servings (p=0,009), eating pieces of bread, white bread, consuming the meat and meat products more than 3 times per week (p for trend for all <0,001), eating fried foods, sweets and higher intake of eggs, as roasted as boiled was significantly higher in patients (p<0,001). Regular intake of food (p<0,001), eating dairy products (p<0,001), fresh fruit (p<0,001), and fresh vegetables (p<0,001) is significantly more often in healthy subjects. The use of fat was even in childhood in both groups (72,50% respectively 71,80%), but before disease, it was significantly more often in patients (p<0,001) as well as the use of oil (p<0,001). In the univariate model, as the strongest independent risk factor was the irregular nutrition (OR 14,217, p<0,001), used meat products more than 3 times a week (OR 9,525, p<0,001) and fried foods (OR 8,868, p<0,001). As a protective factor, frequent use of fresh vegetables (OR 0,333, p<0,001) and fresh fruit (OR 0,511, p=0,004). In the multivariate model as the strongest risk factor was the irregular nutrition (OR 47,839, p<0,001) and the use of the meat more than 3 times per week (OR 38,925, p<0,001). Conclusion. These findings are very important for further epidemiological research and should improve preventive strategies of this serious disorder in different geografical areas.

Preferring life to death is deeply-rooted in our biology. With the present study, we then asked two questions: can this inclination be transposed to aesthetics, so that a living being is valued as more beautiful than a non-living being? Which visual features guide this process? For these purposes, participants’ eye-gazing was explored while observing, aesthetically judging and judging the vitality status of faces extracted from paintings representing a sleeping or dead subject. In this respect, art comes at hand since it offers the opportunity to assess the aesthetic value of a dead subject. The eye-tracking data revealed an evenly distributed attention across all facial features when viewing the dead, as opposed to the sleeping subjects, where fixations were more numerous and longer on the eye than on the mouth, but not with respect to the nose area. Within the sleeping category, the eye was also the first fixated feature, followed by the nose, suggesting that they represent primary cues indexing vitality. Additionally, the analysis of the responses given during the aesthetic judgment task confirmed preference for the sleeping subjects. These results are discussed against the ‘embodied’ theory of aesthetic perception based on the existence ‘mirror systems’ alongside other theoretical proposals.
