Serije poljoprivede u bazi podataka Republičkog zavoda za statistiku Srbije
Get PDFThe objectives of this Paper have been to examine which data on agriculture can be found in the Statistical Office of the Republic of Serbia Database, and what are the possibilities for the use of the Database in the research and analysis of agriculture. The Statistical Office of the Republic of Serbia Database physically represents normalized database formed in DBMS SQL Server. The methodological approach to the Paper subject is primarily related to modelling and the way of using Database. The options of accession, filtering and downloading of data from the Database are explained. The technical characteristics of the Database were described, indicators of agriculture listed and the possibilities of using Database were analysed. We examined whether these possibilities could be improved. It was concluded that improvements were possible, first, by enriching Database with data that are now only available in printed publications of the Office, and then, through methodological and technical improvements by redesigning the Database modelled on cloud founded databases. Also, the application of the achievements of the new multidisciplinary scientific field - Visual Analytics would improve visualization, interactive data analysis and data management.Ciljevi ovog rada bili su da se istraži koji se podaci o poljoprivredi mogu pronaći u Bazi podataka Republičkog zavoda za statistiku Srbije i kakve su mogućnosti za primenu Baze podataka u istraživanju i analizi poljoprivrede. Baza podataka Republičkog zavoda za statistiku fizički predstavlja normalizovanu bazu podataka formiranu u DBMS SQL Serveru. Metodološki pristup temi rada odnosi se na modeliranje i način korišćenja Baze podataka. Objašnjene su opcije pristupanju, filtriranju i preuzimanju podataka iz Baze podataka. Opisane su tehničke karakteristike Baze, nabrojani su indikatori poljoprivrede, analizirane su mogućnosti korišćenja Baze podataka. Ispitano je da li ove mogućnosti mogu da se unaprede kroz poboljšanje načina skladištenja i pristupa podacima. Zaključeno je da su poboljšanja moguća, i to obogaćivanjem Baze podataka podacima iz oblasti poljoprivrede koji su za sada raspoloživi samo u štampanim publikacijama Zavoda, a zatim, kroz metodološka i tehnička poboljšanja, redizajniranjem Baze podataka po ugledu na cloud zasnovane baze podataka. Takođe, primena dostignuća novog multidisciplinarnog naučnog polja - Vizuelne analitike poboljšala bi vizuelizaciju, interaktivnu analizu podataka i upravljanje podacima
Paradigma specijalnog tjelesnog odgoja u edukaciji i obuci policije
No full textThe aim of this paper is to present the scientific basis of Special Physical Education and the necessity of applying knowledge, abilities and skills which are developed in police. Special Physical Education (SPE) is studied on all levels of police education, training and improvement in the Republic of Serbia. According to the scientific nomenclature, it is a part of police sciences, actually the group of special police sciences. As a teaching discipline it belongs to the group of narrowly professional subjects, whereas at police colleges it is one of the main subjects. Education and training in SPE is based on science, scientific methods and police practice, and together with other scientific disciplines contributes to the development of personal integrity and professional capacity of each police officer, by involving specially designed educational training programs. Educational training programs and materials of SPE are designed in such a way that in relation to similar teaching subjects of they contribute to the development of personal integrity and capacity of police officers, and it’s a good recommendation for all colleges and police institutions both in Europe and the World
Faktori uticaja na znanje i percepciju učenika srednjih škola u Beogradu o prirodnim katastrofama izazvanim klizištima
Get PDFGeospatial and temporal analyses of total number and consequences of various natural disasters in the world, clearly indicate their increase, which creates the necessity for better readiness of the population to react in such situations. At the same time, natural disasters are no longer perceived as a threat to the security of people, but also as a serious threat to national and international security. Therefore, the reasons for mitigating the consequences are concern of every man, society and nation. In this context, education about natural disasters is increasingly gaining in importance, and also is becoming recognized as a key factor in mitigating the consequences of disasters that certainly can not be prevented. The aim of this quantitative research is to determine the perception and actual knowledge of secondary school students in the Belgrade region with respect to the landslide as a natural disaster and security threat and to identify the factors that influence their knowledge and perceptions. The authors use a method of surveying students to identify and describe the factors that influence student knowledge and perceptions about earthquakes. For the purpose of this research, a sample of 3.548 students was drawn from the total population of secondary school students in Belgrade (65.561 students), which equates to 5.4% of the population. With respect to disaster risk reduction, schools should become increasingly important targets for creating and improving the culture of security that includes training youth to respond knowledgably to landslides. Schools should play a key role in providing basic information (knowledge) about potential and actual disasters in the local communities. The research results shows that the students' knowledge of the landslide influence: gender, age, education father, success in school; the perception: sex, fear of natural disasters, education in family and school; and knowledge of safety procedures reactions: age, success in school, living in a household with his grandfather, education in family and school. In view of the evident lack of education about natural disasters in Serbia, the results of this study can be used when creating a strategy for educational programs. Research suggests how to affect secondary school students in order to raise the level of perception and knowledge about landslides.Cilj kvantitativnog istraživanja predstavlja utvrđivanje nivoa i faktora uticaja na percepciju i stvarno znanje učenika srednjih škola na teritoriji grada Beograda o klizištu kao prirodnoj katastrofi. U radu se koristi metod anketiranja učenika kako bi se identifikovali i opisali faktori koji utiču na znanje i percepciju učenika o klizištu. Iz ukupne populacije učenika srednjih škola u Beogradu (65.561 učenika), za potrebe istraživanja izvučen je uzorak veličine 3.548 učenika, što čini 5,4% populacije. Od 101 beogradske srednje škole, na slučajan način izabrano je njih 13. Rezultati istraživanja pokazuju da na znanje učenika o klizištu statistički značajno utiču (r lt 0,05): pol, starost, obrazovanost oca, uspeh u školi; na percepciju: pol, strah od prirodnih katastrofa, edukacija u porodici i školi; i na poznavanje bezbednosne procedure reagovanja: starost, uspeh u školi, život u domaćinstvu sa dedom, edukacija u porodici i školi. Istraživanjem je obuhvaćen grad Beograd, tako da se zaključci mogu generalizovati samo na populaciju učenika srednjih škola na tom geoprostoru. Imajući u vidu evidentan nedostatak obrazovanja o prirodnim katastrofama u Srbiji, rezultati istraživanja se mogu iskoristiti prilikom kreiranja strategija obrazovnih programa, što bi doprinelo unapređenju bezbednosne kulture mladih, a time i njihove bezbednosti
Impact of climate change on the distribution of extreme temperatures as natural disasters
Get PDFMuch of the scientific community agrees that global temperature as a result of climate change has increased significantly in the last century, and will continue to grow in the near future. According to the Third Assessment Report of the IPCC, 2001 (IPCC - Intergovernmental Panel on Climate Change), the global average temperature has increased by about 0.6 degrees in the 20th century, although climate warming was not uniform neither spatially nor temporally, as was indicated by observed changes and modelling studies. Variations in global or regional cases of extreme air temperatures that occurred due to changes in climate cause more and more attention lately as living beings and ecosystems and human society are sensitive to the severity, frequency and persistence of cases of extreme temperatures. In this regard, in order to effectively protect and respond to emergencies caused by harmful temperature extremes, it is necessary among other things to comprehensively investigate the mentioned natural phenomenon, so the subject of this paper will be an analysis of climate change as well as form, consequences, temporal and geospatial distribution of extreme temperatures. Using an international database on natural disasters of the Centre for Research on the Epidemiology of Disasters (CRED), based in Brussels, with the support of program for statistical analysis (SPSS) and the method of thematic cartography, we have tried to point out the number, trends, consequences, temporal and geospatial distribution of extreme temperature in the period from 1900 to 2013, as well as the need for an adequate response of society to this type of natural hazard
Genetic basis of aggression: Overview and implications for legal proceedings
No full textHistory and patterns of aggressive behavior represent an integral part of the offender's profile during forensic investigations. Traditionally, the majority of evidence on determinants of criminal behavior is contributed by environmental data. In the past two decades, a growing body of research in the fields of neurobiology and genetics has immensely enriched our understanding of the topic. This paper provides a systematic overview of genetic factors believed to govern the development of aggressive and criminal behavior in humans. A particular emphasis is given to the polymorphisms of genes involved in serotonergic and dopaminergic metabolisms in relationship to varying aggressive behavioral outcomes. In addition to approaches focused on individual genes, whole genome analyses, interplay between genetic factors, as well as gene-environment interactions, are also discussed with respect to this complex behavior. Finally, severity of incorporating these findings into the justice system, as well as the importance of considering them in contemporary criminalistics, are contemplated
Optimization Algorithms in Function of Binary Character Recognition
No full textThe paper gives an analysis of some optimization algorithms in computer sciences and their implementation in solving the problem of binary character recognition. The performance of these algorithms is analyzed using the Optimization Algorithm Toolkit, with emphasis on determining the impact of parameter values. It is shown that these types of algorithms have shown a significant sensitivity as far as the choosing of the parameters was concerned which would have an effect on how the algorithm functions. In this sense, the existence of optimal value was found, as well as extremely unacceptable values
Modelling of Characteristics of a Crater Emerged from a Surface Explosion on the Soil
No full textThe paper presents empirical and numerical models of characteristics of a crater emerged from a surface explosion of a small TNT charge on the soil. The proposed models can be useful for estimation of the explosive mass based on the crater characteristics. The models show satisfactory fitting with the experimental results and confirm the hypothesis that the crater characteristics depend on the explosive mass and contact area between the charge and the soil surface. Two equations for estimation of the explosive mass based on the crater volume are proposed
Knowledge and Perception of Secondary School Students in Belgrade about Earthquakes as Natural Disasters
Get PDFThe aim of this quantitative research is to determine the perception and actual knowledge of secondary school students in the Belgrade region with respect to earthquakes as a natural disaster and security threat, and to identify the factors that influence their knowledge and perceptions. The authors used a method of surveying students to identify and describe the factors that influence student knowledge and perceptions about earthquakes. For the purpose of this research, a sample of 3,063 students was drawn from the total population of secondary school students in Belgrade (65,561 students), which equates to 4.67% of the population. The results show that the sources of information on natural disasters and their threatening consequences influence the perceptions of secondary school students. In view of the evident lack of education about natural disasters in Serbia, the results of this study can be used when creating a strategy for educational programs. This research is the first step in developing and realizing a future strategy for natural disaster management by informing and including public (school population), scientific, and administrative communities in the process
