The region of Middle East has been for centuries space of interweaving of interests of power holders, both within the countries of the region and major world powers. The favorable geographical ...position and significant reserves of natural resources, principally oil, make the Middle East, in terms of security, very sensitive. Clash of civilizations and religions in the region and the locations of the most important holy places for both Christianity and Islam were historically a stumbling rock and a great obstacle to peace and prosperity. The aim of this article is to point out and to attempt to answer the question how Islamic State can influence on a global security. Considering the complexity of the security reality in the Middle East, it can be said that the importance is reflected in the fact that it provides a contribution to its knowing the aspect that arises from the problem issues.
The authors analyze the implementation of the concept of flexible use of airspace in the Republic of Serbia, which deals with problems related to airspace capacity. The problem of airspace capacity ...and air traffic that takes place in it was not seriously considered in Europe before the Second World War, due to the simple fact that the number of flights in that period was relatively small. Achieving this goal and solving the problem is being sought in a better organization of the airspace of Europe, which directly influences the organization and strategy of the development of the airspace of all countries in Europe and the Republic of Serbia (as a signatory and a member of international organizations dealing with traffic management and airspace organization ). The concept of flexible use of airspace should provide a solution to this problem. The implementation of the concept requires some legal and organizational solutions, so a wider national concept is needed for a consistent implementation of the concept. The problems encountered by the creators of the concept in Europe and Serbia and the solutions that have been made are the subject of this paper. The content of the paper is presented through several questions to give an overview of the problem of airspace capacity and an increase expected in the upcoming period. The paper also deals with the division of airspace in the world and in our country; planning, registering and announcing flights; the concept of flexible use of airspace; and the problems of applying the concept in Serbia. / В данной статье представлен анализ концепции гибкого использования воздушного пространства, делая особый акцент на вызовы при ее внедрении в Республики Сербия, учитывая все проблемы, связанные с размером и границами воздушного пространства. Надо подчеркнуть, что проблемой размеров и границ воздушного пространства, также как и вопросами воздушных маршрутов до Второй мировой войны в Европе никто всерьез не занимался, по причине малого количества полетов в те времена. В качестве решения настоящей проблемы авторы данной статьи предлагают улучшение организации воздушного пространства Европы, что напрямую влияет на организацию и стратегию развития воздушного пространства всех европейских стран, в том числе и Республики Сербия (как члена и подписчика международных организаций, которые занимаются управлением авиамаршрутов и организацией воздушного пространства). Концепция гибкого использования воздушного пространства должна решить эти проблемы. Однако для внедрения вышеупомянутой концепции требуется пересмотреть раннее законодательские и организационные нормативы, и соответственно первоначально достичь национального консенсуса, в целях последовательного внедрения данной концепции. Проблемы, с которыми столкнулись создатели концепции в Европе и Сербии и решения, которые могут помочь решить эти проблемы представлены в настоящей работе. Структура работы была организована в виде ответов на многие ключевые вопросы по данной тематике, приведен обзор проблем, связанных с размером и границами воздушного пространства и улучшенных перспектив, которые ожидаются в ближайшее время; приведена сопоставительная классификация воздушного пространства; а также методы планировки, регистрации и объявлении о полете, описана концепция гибкого использования воздушного пространства и освещены проблемы при ее применении в Республике Сербия. / U radu je analizirana implementacija koncepta fleksibilnog korišćenja vazdušnog prostora u Republici Srbiji, koji se bavi problemima koji se odnose na kapacitet vazdušnog prostora. Pre Drugog svetskog rata kapacitet vazdušnog prostora i avio-saobraćaj koji se odvijao u njemu nije ozbiljnije razmatran u Evropi, zbog činjenice da je broj letova u tom periodu bio relativno mali. Danas se traži da se vazdušni prostor Evrope bolje organizuje, što direktno utiče i na organizaciju i strategiju razvoja vazdušnog prostora svih zemalja u Evropi, pa i Republike Srbije (kao potpisnika i člana međunarodnih organizacija koje se bave upravljanjem saobraćaja i organizacijom vazdušnog prostora). Koncept fleksibilnog korišćenja vazdušnog prostora treba da da rešenje za taj problem. Njegova implementacija zahteva neka zakonska i organizacijska rešenja, pa je neophodan širi nacionalni konsenzus. Problemi sa kojima su se susreli tvorci koncepta u Evropi i Srbiji i rešenja koja su doneta predmet su ovog rada. Sadržaj rada izložen je kroz nekoliko pitanja: dat je osvrt na problem kapaciteta vazdušnog prostora i povećanje koje se očekuje u narednom periodu; prikazana je podela vazdušnog prostora u svetu i kod nas; opisan je način na koji se vrši planiranje, prijava i najava letova, kao i sam koncept fleksibilnog korišćenja vazdušnog prostora i problemi koji se javljaju pri primeni koncepta u Srbiji.

Painful shoulder in patients on chronic haemodialyis is most often associated with dialysis arthropathy or accumulation of deposits containing modified fibrils of beta2- microglobuline especially in ...bones and joints due to insufficient elimination during the therapy. The aim of this study is to investigate whether there is connection between painful shoulder and plasma level of beta2-microglobuline and to corroborate that with morphologic parameters found in proved amyloidosis. It has to be emphasized that even other causes may contribute the development of painful shoulder. Real time sonography and conventional plain radiographs of the 108 shoulders were performed in 54 patients receiving chronic haemodialysis as a treatment of terminal renal failure (without previous history of rheumatoid arthritis), 27 symptomatic with persistent pain and stiffness in both shoulders and lasting for more than 6 weeks and restriction of movements in various degree and 27 asymptomatic. Plasma level of beta2-microglobuline, CRP and uric acid were taken periodically as routine procedure during a one year prospective trial, as well as plasma level of calcium, phosphor and alkaline phosphatase. Plasmatic level of beta2-microglobuline is strongly connected with painful shoulder in dialyzed patients, as well as CRP as sign of acute inflammation. That is proved by morphologic parameters associated with histological proved amyloidosis in patients on long term dialysis, more then 10 years.
The study included 318 asbestos exposed workers. The aim was to investigate the symptomatology and clinical findings over an average period of ten years. We took in cosideration quantitative data and ...analyzed them by statistical methodology of univariate and multivariate data analysis and chi2-test. Chest radiography, clinical and functional findings were used as a diagnostic tool. The most common finding was dyspnea, then cough and chest pain. Clinical symptoms were more common in workers exposed to crysotile asbestos than in those exposed to crocidolite asbestos. There is strong evidence for association between the symptoms and the duration of asbestos exposure. The symptoms were not specific for asbestosis. A significant positive correlation was found between physical examination and duration of asbestos exposure. Basal rales and pleural rub were recorded in 72% of exposed workers.
Tuberculosis with the incidence 28-29/100000 residents still presents a major public health problem in Croatia. Miliary tuberculosis is uncommon cause of fever of unknown origin. Intestinal ...tuberculosis pose as diagnostic problem that can be identified by colonoscopy and/or explorative laparatomy involving histopathology and microbiology. A case is reported of a 40-year-old HIV negative patient admitted to the Department of Infectious Diseases after two weeks of fever, diarrhea, abdominal pain and weight loss. Biochemistry testing showed mild elevation of the erythrocyte sedimentation rate and increased serum aminotransferases. On admission, chest x-ray was normal and tuberculin skin test was negative. Crohn's disease was suspected. Computed tomography of the abdomen revealed solid infiltrative mass located retroperitoneally, along with enlarged lymph nodes. Explorative laparoscopy was necessary to confirm the diagnosis. Intraoperative specimens were referred for histopathologic and microbiologic examination, which proved the existence of granulomatous inflammation of the areas with caseous necrosis. Direct microscopy of the periappendicular abscess and Ziehl-Neelsen staining of a lymph node specimen confirmed the presence of an acidoresistant bacillus. The specimen culture on solid egg based agar (Löwenstein Jensen) and liquid broth (MGIT) showed the growth of Mycobacterium tuberculosis. Then the causative agent was cultured from all specimens: sputum, stool and urine. Repeat cheast x-ray, performed on day 30 of hospitalization, showed miliary dissemination to the lungs. The patient was treated with four antituberculotics (streptomycin, isoniazide, rifampin, ethambutol) and methylprednisolone for one month, then with isoniazide, rifampin and for 11 months ethambutol. Therapy led to a decrease of abdominal lymph nodes and absence of miliary lesions on chest radiography after two months of treatment. Intestinal tuberculosis has been almost forgotten in Croatia. The latest published cases referred to HIV infected patients. In less than 50% of patients with intestinal tuberculosis the lungs are also affected, which poses a diagnostic problem. Crohn's disease is the most common diagnostic problem. Histopathology of a specimen obtained on colonoscopy and/or explorative laparoscopy can often solve the dilemma, as also confirmed in our patient. Of diagnostic studies, computed tomography has the advantage of evaluating intestinal wall involvement, which is important for the early diagnosis of intestinal tuberculosis. Enteroclysis and irrigography provide diagnostic information in the advanced stage of intestinal tuberculosis. In a patient with fever, abdominal disorders and parameters which implicate granulomatosis hepatitis or Crohn's disease, the existence of abdominal tuberculosis is also possible. Computed tomography and biopsy obtained on colonoscopy for microbiology can help in making the diagnosis and initiating appropriate treatment.
