Injuries of the tarsometatarsal joints: treatment and outcome [Lisfrancova ozljeda]
Between January 2005 and May 2009, a total of 26 patients, 21 males and 5 females, were admitted for treatment of Lisfranc lesion. All patients were radiologically evaluated and classified according to the criteria proposed by Myerson: 5 (19.2%) patients had a type A injury, 2 patients (7.7%) presented with a type B1 injury, 17 (65.4%) sustained the most common type B2 injury and 1 (3.8%) patient suffered from a type C1 and C2 injury. Taking radiological and clinical findings in account, fifteen patients were elected for operative treatment and eleven patients were treated conservatively. According to type of fracture we established three groups; in group I metatarsal fracture was found in fourteen (53.9%) patients, group II with phalangeal fracture in three (11.5%) cases, whereas in group III nine (34.6%) patients sustained combined metatarsal, navicular and, most commonly, a cuneiform fracture. Using the American Orthopedic Foot and Ankle Society (AOFAS) midfoot scoring scale and SF-36 questionnaire, the functional outcome was assessed. The mean value for age distribution was 42.7 +/- 13.2 years and the mean follow up was 27.9 +/- 12.4 months. A p value < 0.005 was regarded as statistically significant for the analysis of the results. We found by means of SF 36 questionnaire a statistically significant difference in the role limitation due to existence of pain (p = 0.04) and poor general health (p = 0.013) in the group of patients that sustained combined foot fracture. The purpose of this study is to assess the treatment of Lisfranc injuries in our patients, according to SF36 and AOFAS criteria, clinical outcome was evaluated. In the group I the mean AOFAS score was 74.0 +/- 9.1 and in the group II it reached 72.0 +/- 5.2 signifying fair outcome! Poor outcome was present in the group III with mean AOFAS score 67.1 +/- 9.0. All unstable injuries require surgery. Clinical outcome is highly dependent on the restoration of normal anatomic alignment
Zakoni Republike Italije o obaveštajno-bezbednosnom sistemu i režimu državne tajne
In the last couple of years almost all European countries have passed legislation which regulates organization and functioning of information-security system. This is also the case with Italy, a country which has a long tradition of legal regulation of information-security and protection of data secrecy. The Act No. 801 of 1977 on establishment and organization of services for information and security and state secret is surely one of the most important legal sources in this area. High quality solutions which it contains have remained in force for three full decades, in spite of frequent periods of political instability. Nevertheless, the current information-security system is based on a fully new regulation – Act No. 124 on Information system for security of the Republic and new regulation of state secret. On the basis of this Act of 2007, some of the key information and security institutions of the Republic of Italy have been reorganized or renamed.Poslednjih godina su gotovo sve evropske države donele zakone kojima regulišu organizaciju i funkcionisanje bezbednosno-obaveštajnog sistema. Ovo je slučaj i sa Italijom, zemljom koja ima dugu tradiciju zakonskog regulisanja slučaj i sa Italijom, zemljom koja ima dugu tradiciju zakonskog regulisanja obaveštajne delatnosti i zaštite tajnosti podataka. Zakon broj 801 iz 1977. godine o osnivanju i organizovanju službi za informisanje i bezbednost i režimu državne tajne svakako je jedan od najznačajnijih pravnih izvora u ovoj oblasti uopšte. Kvalitetna rešenja koja sadrži, i pored čestih perioda političke nestabilnosti, ostala su na snazi pune tri decenije. Ipak, aktuelni bezbednosno – obaveštajni sistem počiva na potpuno novom propisu - Zakonu broj 124 o informativnom sistemu za bezbednost Republike i novom režimu tajne. Na osnovu tog propisa iz 2007. godine, reorganizovane su ili preimenovane neke od ključnih obaveštajnih i bezbednosnih institucija Republike Italije
SARADNJA GRANIČNIH POLICIJA ZEMALJA EVROPSKE UNIJE – PRIMER SR NEMAČKE I POLJSKE
The European Union developed effective system of border control and management, trough generally accepted integrated border management concept. This concept enables not only free movement of people and goods, but prevention organized crime, and respect high standards of protection of human rights and freedoms in the same time. The system between EU member states establish in that way needs introduction high standards of organization, authority and cooperation model of border security subjects, on its internal and external borders. In any case, Border police is one of the most significant security border subject in EU. Proceeding from that, the purpose of this work is to present standardization in organization, authority, and especially in models of bilateral cooperation using the example of function of EU border police, concretely Federal Republic of Germany, as “old EU member state” and Republic of Poland, as “new EU member state”.Evropska unija je, kroz opšteprihvaćeni koncept integrisanog upravaljanja granicom, razvila efikasan sistem kontrole i upravljanja granicama. On omogućava slobodan protok ljudi i robe, kao i sprečavanje prekograničnog organizovanog kriminala, uz istovremeno poštovanje visokih standarda zaštite ljudskih prava i sloboda. Ovako uspostavljen sistem između država članica EU, zahteva i uvođenje visokih standarda organizacije, nadležnosti i modela saradnje subjekata bezbednosti granica, kako na unutrašnjim tako i na njenim spoljnim granicama. U svakom slučaju, Granična policija predstavlja jedan od najvažnijih subjekata bezbednosti granica EU. Polazeći od toga, cilj ovog rada je da na primeru funcionisanja graničnih policija EU, konkretno, Savezne Republike Nemačke kao “stare članice EU” i Republike Poljske kao “nove članice EU”, predstavi standardizaciju u njihovoj organizaciji, nadležnostima, a naročito u modelima bilateralne saradnje
BORBA PROTIV VISOKOTEHNOLOŠKOG KRIMINALA U REPUBLICI FRANCUSKOJ
Republic of France is one of the most developed countries of the European Union. In the Republic of France 58.1% of the population used Internet by statistic data from march 2008. The number of users growing steadily since then. Fight against cyber crime was set as a priority in the years 2008 and 2009 by the Ministry of Internal Affairs of the Republic of France in order to preserve the information structure as the basis of modern information society. French laws are constantly adapting modern practices related to high-tech crime suppression. Structure of government bodies intended to fight against this phenomenon in France is an example of an effective system for combating cyber crime. Criminal legal regulations in the Republic of France provide an effective framework for preventing this criminal phenomenon. Harsh sentencing policies that are reflected in the amount of prison sentences, and high fines could be a kind of deterrent factor for crime prevention in this area.Republika Francuska je jedna od najrazvijenijih država Evropske Unije. U martu 2008. godine Internet je u Republici Francuskoj koristilo 58.1% stanovništva, a broj korisnika je od tada u stalnom porastu. Tokom 2008. i 2009. godine borba protiv visokotehnološkog kriminala od strane Ministarstva unutrašnjih poslova Republike Francuske postavljena je kao prioritet radi očuvanja informacione strukture kao osnove savremenog informacionog društva. Francuski zakoni se konstantno prilagođavaju savremenoj praksi vezanoj za visokotehnološki kriminal, a struktura državnih organa Francuske namenjena borbi protiv ovog fenomena predstavlja primer efikasnog sistema za borbu protiv visokotehnološkog kriminala. Krivično pravna regulativa u Republici Francuskoj pruža efikasne okvire za sprečavanje ove pojave. Oštra kaznena politika koje se ogleda u visini zatvorskih kazni koje su zaprećene, kao i zaprećenim novčanim kaznama predstavlja i svojevrstan faktor odvraćanja od izvršenja krivičnih dela iz ove oblasti
Constrained Dynamics of Tachyon Field in FRWL Spacetime
In this paper we continue study of tachyon scalar field described by a
Dirac-Born-Infeld (DBI) type action with constraints in the cosmological
context. The proposed extension of the system introducing an auxiliary field in
the minisuperspace framework is discussed. A new equivalent set of constraints
is constructed, satisfying the usual regularity conditions.Comment: 10 pages, to be published in the Special Issue of the Facta

The shape of Fe K line emitted from relativistic accretion disc around AGN black holes
The relativistically broadened Fe K line, originating from the
accretion disc in a vicinity of a super massive black hole, is observed in only
less than 50\% of type 1 Active Galactic Nuclei (AGN). In this study we
investigate could this lack of detections be explained by the effects of
certain parameters of the accretion disc and black hole, such as the
inclination, the inner and outer radius of disc and emissivity index. In order
to determine how these parameters affect the Fe K line shape, we
simulated about 60,000 Fe K line profiles emitted from the
relativistic disc.
Based on simulated line profiles, we conclude that the lack of the Fe
K line detection in type 1 AGN could, be caused by the specific
emitting disc parameters, but also by the limits in the spectral resolution and
sensitivity of the X-ray detectors.Comment: Based on the talk presented Balkan Workshop BW2018 (10-14 June 2018,

Fire protection problems with large forest fires in Deliblatska peščara (Serbia)
Purpose - The aim of the paper was to investigate the major forest fires in Deliblatska peščara, as well as to analyze the efficiency of fire protection measures. Design / methodology / approach - The analysis included interviews with participants in extinguishing the major fires. The questions referred to the course of fires, as well as to the main fire protection disadvantages. The documentation of the 'Banat' Forest Management - Pančevo (Public Enterprise 'Vojvodinašume') was also used in the paper for the period 1948-2012. Findings - The major forest fires in Deliblatska peščara in the studied period were recorded in 1973, 1990, 1996 and 2007. Although they account for only about 1.5 % of the total number of fires, they collectively have invaded more than half of the total burnt area and more than two-thirds of the forest area. According to the surveys, the main characteristics of these fires were: frequent appearance of new fire hot spots, strong wind variable in direction which crucially affects the spread of fire and the impossibility of direct action on fire. The main disadvantages of fire protection were: inefficiency of fire breaks, blockage of forest roads for the passage of vehicles and the lack of the modern means of fire protection equipment. Research limitations / implications - Given the specificities of the studied area (the absence of surface water, sandy soils, microclimate conditions and vegetation composition), the research results cannot be fully generalized for Serbia. Practical implications - The research results indicate the need for making changes in the fire prevention system, as well as the possibility of fire danger forecast based on the heliocentric hypothesis. Originality / value - What has been the importance of the paper is that it provides the basis for a new approach to the planning of fire prevention measures
Production potential of the soil and the basic elements of productivity of the most widely spred sessil types in the u. N.P. „Đerdap”
This paper is on the results of the soil and its production potential in the types of forests of sessile oaks (Quercus petraea) in the area of the National Park „Đerdap” in the community units of Zlatica, Đerdap, Štrbačko korito, Desna reka and Kožica. There are the most widely spread types of the sprout forests of the sessile oaks in the research area, deep deluvium, luvisoil, eutric cambsoils, and a great number of subtypes of acid brown soil. Considering the fact that the production potential of the defined types of soil depends on the depth, skeleton and other physical characteristics which determine acception, keeping and moving of water and this means that the production value of the studied soils is in the direct correlation with physical-geographical conditions of the environment. Taking into account that solum is well developed and the low contents of skeleton, all the studied soil in the most widely spread types of sessile oaks in the area of N.P. „Đerdap”, are very productive natural habitats. The exception is acid brown soil, which characteristics vary as well as their production potential. Apart from a good production potential of the studied soils within this paper, sessile forests in the researched areas irrationally use production potential of the habitat. In the research area in the last 20 years, the processes of devitalizing and the appearance of decaying of sessile oaks are expressed. In the sessile forests of Serbia, there are forests of the production and protection character, and the structure of the sessile forests at global level is characterized by not normal state with domination of middle aged and in great extent mature withering ingredients, what is the main cause of insufficiently used good potential of the soil
