Introduction: The role of salt in the diet is very important, however what effect will lead to its entry into the organism depends on the amount of salt ingested. Elevated salt intake is a risk factor for hypertension, heart disease, adversely affects the kidneys, helps the development of osteoporosis. The aim was to examine sodium intake in the student population through an objective assessment of nutrition students and the students' subjective experience of salty foods and salty foods influence on the organism.Methods: The research is cross-sectional study, which is carried out in April 2010 among students at the University of Sarajevo.Results: More than half of students from the FHS considers that the greatest amount of salt into the body, adding salt to food during the meal, 34% considered that it was during the preparation of food by 10% of processed products in the food industry and 4% said that it was the intake of salt, which naturally found in foods. Not in a group of students there who suffer from hypertension, while in their families the disease is present.Conclusions: Subjects eat a quantity of salt that are well above the recommended. This problem must be approached in a more organized educational, health educational and research terms.

Introduction: Diabetes mellitus (DM) type 2 is a heterogeneous disorder of complex etiology that occurs in response to genetic influences and impacts of the external environment. There are numerous risk factors thatcontribute to the development of type 2 diabetes such as: heritage, overabundant food and as a consequence of obesity in animals, physical inactivity, the presence of hypertension, psychogenic stress and many others. The aim of this study is to analyze and determine the existence of risk factors for type 2 diabetes in patients of all ages and both sexes treated in the general practice of the Health Centres for municipality Ilidza.Methods: The research is cross-sectional study, which is carried out in February 2010 in the general practice of the Health Centres for municipality Ilidža. Research instrument was a questionnaire and anthropometric measurements.Results: The results show us that in our sample 62% of patients had increased body mass index 25% of male respondents and 48% of females has waist I and II risks, both sexes are fairly large percentage (40%) inactive, a large percentage of respondents (52%) taking antihypertensive medications, 21% of respondents have a genetic predisposition of developing diabetes.Conclusions: There is a risk of developing type 2 diabetes in a large percentage of patients. Risk factors, important for the development of type 2 diabetes, were present at more than half of examinees and promotion of health and healthy lifestyles is necessary in all age groups.

Introduction: The prevalence of pediatric obesity is increasing. Finding the most effective preventive measures for the development of obesity in each country requires accurate epidemiological data on the number of obese children and adolescents, and their habits regarding nutrition and activity. The objective of this study was evaluate diet and physical activity in primary school students in relation to the occurrence of obesity, to determine the prevalence of overweight, mark the basic causes of this phenomenon and to establish measures for treatment and prevention.Methods: pupils 1-8. grades of primary schools were surveyed in written forms in terms of nutrition and physical activity, and measured height and weight, body mass index (BMI-body mass index) was calculated by whichwas estimated the level of nourishment: BMI> p (percentile) 5-malnutrition, p 5-85 proper body weight, p 85-95 over-nutrition, p> 95 obesity.Results: The study comprised 2329 pupils from 10 primary schools in the Canton of Sarajevo. Number of respondents by age and gender was balanced: I-IV 1077, V-VIII 1252; M-1226 and -1103 W. Obese and overweight was 22.46%, 62.53% of normal weight and 15 underweight, 01%. Most children eat a sandwich from school 34.63%, and food from the bakery 23.36% and 23.64% a sandwich from home. Still-dense juices are mostly drunk, even 22.34% of the students, a maximum of 52.8% water. Daily candy had taken 53.21% of all primary school students. 33.80% of the students were active on physical activity lessons and daily only 28.27%.Conclusions: The overweight problem in relation to the way of nutrition and physical activity is evident. The most important factors in] uencing the development of obesity undernutrition of children in school, the high frequency of intake of sweets and thick juice, an inadequate level ofphysical activity and sedanteran way of life.

This chapter treats performances of Maximal-Ratio Combiner (MRC) in presence of two general fading distributions, the κ-μ distribution and the η-μ distribution (Yacoub, 2007.). Namely, performances of Maximal-Ratio Combiner in fading channels have been of interest for a long time, which can be seen by a numerous publications concerning this topic. Most of these papers are concerned by Rayleigh, Nakagami-m, Hoyt (Nakagami-q), Rice (Nakagamin) and Weibull fading (Kim et al., 2003), (Annamalai et al., 2002), (da Costa et al., 2005), (Fraidenraich et al., a, 2005), and (Fraidenraich et al., b, 2005). Beside MRC, performances of selection combining, equal-gain combining, hybrid combining and switched combining in fading channels have also been studied. Most of the papers treating diversity combining have examined only dual-branch combining because of the inability to obtain closed-form expressions for evaluated parameters of diversity system. Scenarios of correlated fading in combiner’s branches have also been examined in numerous papers. Nevertheless, depending on system used and combiner’s implementation, one must take care of resources available at the receiver, such as: space, frequency, complexity, etc. Moreover, fading statistic doesn't necessary have to be the same in each branch, e.g. probability density function (PDF) can be the same, but with different parameters (Nakagami-m fading in i-th and j-th branches, with mi≠mj), or probability density functions (PDF) in different branches are different (Nakagami-m fading in i-th branch, and Rice fading in j-th branch). This chapter treats MRC outage performances in presence of κ-μ and η-μ distributed fading (Milisic et al., a, 2008), (Milisic et al., b, 2008), (Milisic et al., a, 2009) and (Milisic et al., b, 2009). This types of fading have been chosen because they include, as special cases, Nakagami-m and Nakagami-n (Rice) fading, and their entire special cases as well (e.g. Rayleigh and one-sided Gaussian fading). It will be shown that the sum of κ-μ squares is a κ-μ square as well (but with different parameters), which is an ideal choice for MRC analysis. This also applies to η-μ distribution. Throughout this chapter probability of outage and average symbol error rate, at the L-branch Maximal-Ratio Combiner’s output, will be analyzed. Chapter will be organized as follows. In the first part of the chapter we will present κ-μ and η-μ distributions, their importance, physical models, derivation of the probability density function, and relationships to other commonly used distributions. Namely, these distributions are fully characterized in terms of
