INTRODUCTION The burnout syndrome is a response to chronic emotional and interpersonal stressors which are related to workplace. Medicine is one of the professions at the greatest risk of suffering from burnout syndrome. The aim of this study was to assess the presence of stress and burnout syndrome in relation with age and length of service in the family medicine physicians in the Republic of Srpska. MATERIAL AND METHODS The study was carried out on the basis of a questionnaire survey among family medicine physicians in seven Primary Health Care Centres in the Republic of Srpska from February 1st to April 30th 2010. The participants fulfilled the questionnaire for self-assessment of stress level and the Maslach Burnout Inventory, which were amended with data regarding age, sex, length of service and educational and vocational level. RESULTS The study included 199 (83.3%) female and 40 (16.7%) male participants. The physicians aged over 46 years and with the length of service over 21 years had statistically significant higher level of stress and emotional exhaustion than younger participants and participants with shorter length of service. CONCLUSION Age and length of service have important influence on the level of stress and burnout syndrome: the older the physicians and the higher the length of service the higher the level of stress and the higher the risk of burnout syndrome.

In this paper we analyze the requirements for the complex information system used to support a modern global university. We outline the architecture for this system based on the emerging cloud computing platforms and present an example of managing a university course by incorporating different Google cloud services within the Google Sites.

IntroductionFibroadenomas are the most common benign breast tumors in young women. Infarction is rarely observed in fibroadenomas and when present, it is usually associated with pregnancy or lactation. Infarction can exceptionally occur as a complication of previous fine-needle aspiration biopsy or during lactation and pregnancy.Materials and methodsRetrospective review of 650 cases of fibroadenomas diagnosed at our institution during the 8-years period identified two cases of fibroadenomas with infarction (rate ~0.3%).ResultsTwo partially infarcted fibroadenomas were diagnosed on core biopsy and frozen section in an adolescent girl (13 years old) and in a young woman (25 years old), respectively. No preceding fine-needle aspiration biopsy was performed in these cases, nor were the patients pregnant or lactating at the time of the diagnosis.ConclusionSpontaneous infarction within fibroadenoma is a rare phenomenon in younger patients. The presence of necrosis on core biopsy or frozen section should be cautiously interpreted and is not a sign of malignancy.Virtual SlidesThe virtual slide(s) for this article can be found here:http://www.diagnosticpathology.diagnomx.eu/vs/1556060549847356

This paper present a way of developing web applications for mobile devices in NetBiscuit platform which is implemented at the University of Novi Pazar. The process of implementation is based on project management of e-learning, more precisely on the application of project management (through four phases: definition, planning, management and evaluation). It's designed the combination of project management phase which enables more efficient planning and performing online education with the procedure of design courses for e-learning. The final part contains the process of integration of mobile web applications with Learning Management System (LMS).

We study the distribution of zeros of the derivative of the Selberg zeta function associated to a noncompact, finite volume hyperbolic Riemann surface $M$ . Actually, we study the zeros of $(Z_{M}H_{M})^{\prime }$ , where $Z_{M}$ is the Selberg zeta function and $H_{M}$ is the Dirichlet series component of the scattering matrix, both associated to an arbitrary finite volume hyperbolic Riemann surface $M$ . Our main results address finiteness of number of zeros of $(Z_{M}H_{M})^{\prime }$ in the half-plane $\operatorname{Re}(s)<1/2$ , an asymptotic count for the vertical distribution of zeros, and an asymptotic count for the horizontal distance of zeros. One realization of the spectral analysis of the Laplacian is the location of the zeros of $Z_{M}$ , or, equivalently, the zeros of $Z_{M}H_{M}$ . Our analysis yields an invariant $A_{M}$ which appears in the vertical and weighted vertical distribution of zeros of $(Z_{M}H_{M})^{\prime }$ , and we show that $A_{M}$ has different values for surfaces associated to two topologically equivalent yet different arithmetically defined Fuchsian groups. We view this aspect of our main theorem as indicating the existence of further spectral phenomena which provides an additional refinement within the set of arithmetically defined Fuchsian groups.

Copaiba oleoresin is extracted from the trunk of Copaifera sp genus trees and used for treating wounds in several regions of Brazil. Its antimicrobial and anti-inflammatory effects have been proved, however there are no reports of activity on cell growth. Proliferation of MDBK ( Madin Darby Bovine Kidney ) cells was evaluated under the influence of different concentrations of Copaiba oleoresin. Control groups consisted of cells in medium without addition of oleoresin (M group) and cells in the medium with application of the solvent Tween 80 at dilution 10-3 (TM group). Decimal dilutions of 10-1 to 10-3 were shown to be toxic and, therefore, the proliferation studies were conducted from dilution 10-4 to 10-7. Cell growth was faster in all groups that received the Copaiba oleoresin dilutions in the first 24 hours, specially the 10-5 dilution group, which proliferation rate was 5,47 higher than that of M group. It was concluded that Copaiba oleoresin stimulates cell multiplication, which may be one mechanism of its positive effect on wound healing, in association with those previously known.
