Semantic Ontology Design for a Multi-Cooperative First Responder Interoperable Platform

Natural and man-made catastrophic events appear be steadily increasing in intensity and frequency. Proper preparation, response and recovery are essential if mankind and its vital systems are to cope with and survive large-scale disasters. The organisations responsible for delivering emergency response services often under-perform due to a lack of proper interoperation and collaboration. This paper discuss the interoperability issues for data interchange among first responders agency participating in emergency situation and provides exhaustive overview of the recent studies and attempts to solve the problem. The approach taken by the EU funded REDIRNET project for development of a core ontology enabling exchange of data among first responder agencies is presented. The novelty included in the ontology tree is described and the implementation in the meta-data gateway is introduced. The paper provides insight in the implementation of the REDIRNET platform and the designed semantic interoperable services. The paper ends with the discussion of the presented work and the concluding remarks

A methodology for cost-benefit analysis of information security technologies

The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.Although information security technologies (such as digital rights management products) has been proven effective and successful in protecting the confidentiality of sensitive information by providing access control, these technologies have not been widely adopted and used to their potential. One reason for this could be that cost and benefit of these products have not been analysed in a systematic and quantitative manner to date. As a result, companies do not have an established procedure to evaluate the cost and benefit of implementing these products. In this document, the benefits of implementing a digital rights management product in enterprises are quantified using stochastic Petri nets models and are compared with the security needs of a corporation and potential costs incurred by the implementation process. An evaluating procedure for implementing these products is established. This procedure has the potential to be used to improve the ability of a corporation to make sensible security investment decisions

Economic Valuation for Information Security Investment: A Systematic Literature Review

Research on technological aspects of information security risk is a well-established area and familiar territory for most information security professionals. The same cannot be said about the economic value of information security investments in organisations. While there is an emerging research base investigating suitable approaches measuring the value of investments in information security, it remains difficult for practitioners to identify key approaches in current research. To address this issue, we conducted a systematic literature review on approaches used to evaluate investments in information security. Following a defined review protocol, we searched several databases for relevant primary studies and extracted key details from the identified studies to answer our research questions. The contributions of this work include: a comparison framework and a catalogue of existing approaches and trends that would help researchers and practitioners navigate existing work; categorisation and mapping of approaches according to their key elements and components; and a summary of key challenges and benefits of existing work, which should help focus future research efforts

Cyber risk assessment in cloud provider environments: Current models and future needs

Traditional frameworks for risk assessment do not work well for cloud computing. While recent work has often focussed on the risks faced by firms adopting or selecting cloud services, there has been little research on how cloud providers might assess their own services. In this paper, we use an in-depth review of the extant literature to highlight the weaknesses of traditional risk assessment frameworks for this task. Using examples, we then describe a new risk assessment model (CSCCRA) and compare this against three established approaches. For each approach, we consider its goals, the risk assessment process, decisions, the scope of the assessment and the way in which risk is conceptualised. This evaluation points to the need for dynamic models specifically designed to evaluate cloud risk. Our suggestions for future research are aimed at improving the identification, assessment, and mitigation of inter-dependent cloud risks inherent in a defined supply chain

Semantic and pragmatic aspects of identity markers in english

Magistrsko delo obravnava semantične in pragmatične vidike rabe identitetnih označevalcev v sodobni angleščini. Prvi del vsebuje nekaj sodobnih definicij in načinov razumevanja identitete, teorije pomena s poudarkom na konceptualnih teorijah pomena besed, ter poglavje o kategorizaciji kot prirojena lastnost uma, ki se izraža v rabi jezika. Prvi, teoretični del je predvsem usmerjen na semantiko, drugi, praktični del pa na semantične in pragmatične aspekte rabe označevalcev. Drugi del naloge vsebuje kategorizacijo identitetnih označevalcev glede na pragmatične ozire. Pragmatični oziri so razumljeni v smislu praktične delitve različnih področij življenja, ki se v jeziku izražajo preko imen raznoraznih vidikov identitete. Delitev vsebuje štiri področja, ki se mestoma prekrivajo. Posamezniki se lahko istovetijo z lastnim imenom, s fizičnimi in nefizičnimi lastnostmi in stanji, z nazori ter z družinskimi in ostalimi medosebnimi odnosi. Poglavje o pragmatični obravnavi identitetnih označevalcev nato opiše, kako se z njimi manipulira in kako jih je možno razumeti v diskurzu. Obravnava rabo označevalcev z namenom žalitve, sramotenja, hvale, metaforičnega izražanja, z zanašanjem na stereotipne predstave, itd. Vsebuje tudi kratko sintaktično in pravopisno obravnavo njihove rabe.This thesis investigates semantic and pragmatic aspects of identity markers in contemporary English. In the first part, it overviews some current definitions and understandings of identity, theories of meaning with a focus on conceptual theories of meaning, and categorisation as an innate function of the mind which is expressed in language. The first, theoretical part is predominantly semantics-oriented, whereas the second includes semantic and pragmatic considerations. The second part includes a categorisation of identity markers according to the pragmatic viewpoint. The pragmatic viewpoint is to be understood in the sense of practical and meant to display all the different areas of human experience that are expressed through language as names for aspects of identity. They are put into four groups which may overlap in some instances. People are identified by proper names, physical and non-physical conditions, beliefs, and kin and other inter-personal relations. The chapter on pragmatic considerations of identity markers then explores how their use may be manipulated and interpreted in discourse, through intentions of causing offence and shame, giving praise, speaking figuratively, relying on stereotypes, etc. It also looks at how markers are expressed syntactically and orthographically

Kvantitativni model za ekonomsko analizo naložb v informacijsko varnost v poslovnem informacijskem sistemu

The paper presents a mathematical model for the optimal security-technology investment evaluation and decision-making processes based on the quantitative analysis of security risks and digital asset assessments in an enterprise. The model makes use of the quantitative analysis of different security measures that counteract individual risks by identifying the information system processes in an enterprise and the potential threats. The model comprises the target security levels for all identified business processes and the probability of a security accident together with the possible loss the enterprise may suffer. The selection of security technology is based on the efficiency of selected security measures. Economic metrics are applied for the efficiency assessment and comparative analysis of different protection technologies. Unlike the existing models for evaluation of the security investment, the proposed model allows direct comparison and quantitative assessment of different security measures. The model allows deep analyses and computations providing quantitative assessments of different options for investments, which translate into recommendations facilitating the selection of the best solution and the decision-making thereof. The model was tested using empirical examples with data from real business environment.V prispevku je predstavljen matematični model za vrednotenje naložb v varnostne tehnologije in odločitvene procese na podlagi kvantitativne analize varnostnih tveganj ter različnih varnostnih ukrepov, ki zmanjšujejo posamezna tveganja. Za vse ugotovljene poslovne procese se določijo želene stopnje varnosti, verjetnost za varnostni incident ter morebitna izguba, ki jo lahko utrpi podjetje. Izbor varnostne tehnologije temelji na učinkovitosti izbranih varnostnih ukrepov, pri čemer se za ocenjevanje učinkovitosti in primerjalno analizo različnih varnostnih tehnologij uporabljajo ekonomski kazalci. Za razliko od obstoječih modelov za oceno naložb v informacijsko varnost, omogoča predlagani model neposredno primerjavo in kvantitativno oceno različnih varnostnih ukrepov. Model omogoča podrobno analizo kvantitativnih ocen za različne vrste naložb, ter podaja priporočila, ki omogočajo izbiro optimalne varnostne rešitve. Model je bil testiran z uporabo praktičnih primerov s podatki iz realnega poslovnega okolja

Modernization of locomotive lifting jacks system

Diplomska naloga temelji na prenovi in posodobitvi krmiljenja pogonov dvigalk za dviganje lokomotiv v podjetju SZ – VIT. Potreba po obnovi krmilnega sistema se je pokazala ob nekontroliranem delovanju, ki je izpostavilo določene pomanjkljivosti sistema glede zanesljivosti, predvsem pa varnosti za ljudi in lokomotive. Pri spustu oziroma dvigu lokomotive ni deloval eden od pogonov dvigalk, kar je povzročalo nesimetrično premikanje dvigala in brez ukrepanja operaterja bi lahko prišlo do nesreče z večjo materialno škodo. Analiza dogodka je razkrila več pomanjkljivosti obstoječega krmilnega sistema. Brez avtomatizacije in nadzora delovanja pogonov je bilo zanesljivo in varno delovanje zelo odvisno od pozornosti operaterja. V okviru diplomske naloge je prikazan postopek izvedbe avtomatizacije delovanja obstoječega sistema dvigalk za dviganje lokomotiv, od načrtovanja projekta za izvedbo, izdelave krmilnih omar z ožičenjem energetskih in krmilnih elementov, izdelave programske opreme, testiranja signalov, do zagona in izdelave projekta izvedenih del. Za takšno avtomatizacijo je potreben programirljivi krmilnik (PLC), kjer se izvajajo logične operacije. Za določanje pozicije posameznih dvigalk so bili uporabljeni induktivni senzorji in končna stikala, ki so povezani s krmilnikom. Za varnost sistema pa je uporabljen varnostni rele, preko katerega se nadzira izklop tipkal za izklop v sili in zaščitni elementi pogonskih motorjev. S prenovo smo dosegli višji nivo varnosti in večjo zanesljivost delovanja sistema. Prav tako smo podaljšali življenjsko dobo strojnih elementov dvigalk, ki so bili pred prenovo veliko bolj izpostavljeni obrabi. Pri opisani avtomatizaciji smo zaradi omejenih finančnih sredstev v večji meri uporabili obstoječe krmilne in energetske stikalne elemente, ki so bili res že malo v letih, vendar še vedno tehnično brezhibni in v popolnosti opravljajo svojo funkcijo. Ob spremembi finančne situacije v prihodnosti bi lahko sistem še nadgradili.The thesis is based on the renewal and modernization of control system for lifting locomotives in the company SZ – VIT. The need for renewed control system has been seen during uncontrolled operation, which highlighted certain shortcomings in the system of reliability, in particular, the safety of people and the locomotives. At lifting or lowering locomotive, one of the motors didn\u27t work properly, which caused asymmetric vertical movement of the locomotive and without operator\u27s intervention, it could lead to accidents with major material damage. Analysis of the incident revealed several weaknesses of the existing control system. Without automation and control of the drives, reliable and secure operation were highly dependent on the operator\u27s attention. The thesis shows the process of implementation of the existing automation system for lifting locomotives, from project planning for execution, manufacturing control cabinets with wiring of power and control elements, software development, testing signals, the start-up and design of the project works carried out . Such automation requires a programmable logic controller (PLC), which carries out logical operations. To determine the position of the individual jacks, we used inductive sensors and limit switches, which are connected to the PLC. For the safty of the system we used safety relay, which controlls emergency stop buttons and bimetal circuit breakers for motors. With the renovation we have achived a higher level of security and increased reliabilty of the system. We have also extended the life time of machine elements. Because of limited financial resources, we used many of old existing working elements, which were getting a bit over the years, but still performing their function. At the different financial situation in the future, the system can be upgraded

IMPROVING HEALTH AWARENESS AS A VALUE AMONG THE ROMA PEOPLE IN THE DOLENJSKA REGION

Teoretična izhodišča, namen: Temeljni cilj vsake družbe na področju zdravja in zdravstvenega varstva je izboljšati zdravje prebivalstva in zmanjšati breme bolezni, zmanjševati neenakosti glede zdravja ter zagotoviti sistem, ki posamezniku v bolezni zagotavlja pravično, pravočasno in kakovostno oskrbo ter čimprejšnjo povrnitev zdravja. Na zdravje vplivajo številni med seboj prepleteni dejavniki, t. i. determinante zdravja. Krepitev in varovanje zdravja posameznika pa zahtevata celovit pogled in sodelovanje tako posameznika kakor celotne družbe. Namen raziskave je opisati, raziskati in analizirati življenjske razmere, v katerih živijo dolenjski Romi ter opozoriti na potrebne ukrepe za izboljšanje dostopnosti do zdravstvenih storitev za Rome na območju Dolenjske. K delu z Romi je potrebno pristopiti etnično občutljivo. Prezrta ne sme biti nizka izobrazbena raven Romov, pripravi primernih učnih pripomočkov zanje pa posvečena posebna skrb. Raziskovalna metodologija: V raziskavi smo uporabili kvantitativno metodologijo. V okviru empiričnega dela smo s pomočjo Student t-testa ter ostalih statističnih testov obdelali podatke, pridobljene z anketnim vprašalnikom, ki smo ga razdelili v štirih največjih romskih naseljih, ki se razlikujejo po urejenosti bivalnih razmer, številčnosti družin in njihovega ekonomskega statusa. Rezultati: Več kot polovica Romov je v raziskavi potrdila, da ne živi zdravo. Njihova prehrana je raznolika, najpogosteje uživajo meso 26 % in kruh 20 %, zelenjavo 8 % in jajca 1,5 %. 63,7 % Romov je kadilcev, 10 % jih je začelo kaditi pri 10-ih letih starosti. 96 % jih je že poskusilo drogo ali alkohol. 47 % Romkinj, ki že same trdijo, da ne živijo zdravo ne obiskujejo ginekologa v času nosečnosti. Med temi Romkinjami najdemo 40 % takih, ki so rodile pred 16. letom starosti. Iz raziskave sledi, da vsi Romi, ki imajo redno službo, živijo zdravo. Romi, ki se preživljajo s prejemki socialnih pomoči in drugimi občasnimi prejemki, pa so odgovorili, da ne živijo zdravo. Sklep: Romska populacija sodi med socialno ogrožene skupine prebivalstva s povečanim tveganjem glede zdravja. Večina jih živi v neustreznih življenjskih razmerah, mnogokrat celo brez osnovnih življenjskih možnosti, s čimer sta povezani neustrezna higiena in slaba prehrana. Oba dejavnika neposredno zvišujeta stopnjo zdravstvene ogroženosti. Slab ekonomski položaj in neizobraženost populacije sta razloga za zdravstveno neinformiranost in nizko ozaveščenost o pomenu zdravja, kar se pogosto odraža v odsotnosti preventivnih oblik zdravstvenega varstva.Theoretical starting points, aim: The basic goal of every society regarding health and health care is, generally, to improve the health of the population and to consequently reduce the burden of illness, to reduce inequality regarding health and to ensure a system, which will enable every individual, when ill, a just, timely and good-quality medical care and a reasonably fast recovery. Health itself is influenced by many intertwined factors, or so-called health determinants. Health strengthening and health protection for every individual demands a comprehensive view and cooperation between the individual and the whole society. The aim of this analysis is to describe study and analyse the living conditions regarding the Roma population in the Dolenjska region and to suggest the necessary steps that need to be taken in order to improve the availability of health care services. In order to work with the Roma population, it is necessary to take into account their cultural and ethnical characteristics. Their low level of education cannot be ignored and due to this, special care for the preparation of adequate learning material must be given. Research methodology: In this research, quantitative methodology has been used. Within the empirical part, we have analysed the data with the help of Student T-test and other statistical tests, gathered by using the survey questionnaire, which was distributed in four major Roma settlements, which differ from each other regarding the quality of living conditions, the number of family members and their economic status. Results: More than half of the Roma population surveyed confirmed that they do not live a healthy life. Their nutrition is varied, as 26 % most often eat meat and 20 % bread, while 8 % eat vegetables, and 1,5 % eat eggs. 63,7 % of the surveyed Roma are smokers, among whom 10 % started to smoke at the age of ten. 96 % of the interviewed have already tried drugs or alcohol. 47 % of the Roma women claim that they do not lead a healthy life and do not see the gynaecologist when pregnant. Among the surveyed Roma women, there are 40 % who gave birth before sixteen years of age. The survey suggests that all those surveyed Roma, who have a regular job, also live a healthy life, while the surveyed Roma, who are on social support and other social benefits, do not live a healthy life. Conclusion: The surveyed Roma population is among the socially endangered population groups with increased health risks, as most of them live in unsuitable living conditions, in many cases even without basic living options, which is also connected with unsuitable hygiene and nutritionboth factors thus indirectly increase the level of health risk. The low economic status and the population´s illiteracy are the main reasons for their lack of information regarding health care and consequently for their low understanding of the importance of good health, which can be frequently observed in the lack of any forms of preventive health care

Planar curves with names of Greek origin

In the thesis we presented few mathematicians and plane curves associated with them. We focused on the curves with the name of Greek orgin. We found a Greek name for each curve, described it and presented in a graphical form with the mathematical program GeoGebra. Part of the thesis, where the curves are presented, is in the form of a dictionary
