Taking the Iwaniec explicit formula as a starting point, we give a short proof of a more precise 2 3 bound for the exponent in the error term of the Gallagher-type prime geodesic theorem for the modular surface.

RESUMO O presente estudo teve como objetivo avaliar a implantacao das acoes do Programa de Controle da Esquistossomose (PCE) em tres municipios da Mata Sul de Pernambuco. Trata-se de uma avaliacao normativa, com a realizacao de entrevistas semiestruturadas com profissionais da vigilância em saude e da atencao basica. Os resultados encontrados demonstram que os municipios estudados obtiveram o grau nao implantado. Como pontos criticos, observaram-se deficiencias na gestao e na execucao de acoes de educacao em saude. Porem, e importante ressaltar que, nos tres municipios avaliados, foi possivel constatar um envolvimento relevante da atencao basica nas acoes do PCE.

Aim: The aim of this study is to prove the advantages of combined use of T2 weighted three dimensional (T2 W 3D) and T1 weighted three dimensional contrast medium enhanced (T1 W 3D CE) magnetic resonance (MR) urography in displaying urinary tract in child population. Material and methods: Total of 120 patients were included in the study, 71 (59%) male patients and 49 (41%) female patients. The study was conducted on the Radiology clinic, University of Sarajevo Clinical Center, during the period from February to November 2016. Patients were examined on the 1.5T and 3T MRI, with standard protocol which includes T2 W 3D and T1 W 3D contrast medium enhanced MR urography. In the post procesing quantitative measurement of signal intensity and evaluation of the display quality in the area of renal pelvis, middle of ureter and the mouth of the ureter were done. Measurement was concluded on Syngo software B13. Results: Analyzing the acquired data and statistically processing them we got results which have shown higher signal intensity of measured structures on T1 W 3D contrast medium enhanced MR urography on the level p<0.01 and p<0.05 compared to T2 W 3D MR urography in patients that had normal dynamics of contrast medium secretion. However, in kidneys with decreased function, T2 W 3D MR urography provided higher signal intensity and better display compared to T1 W 3D contrast medium enhanced MR urography on the level p<0.05 and p<0.01. Conclusion: T2 W3D MR urography is useful in imaging nonfunctional kidney as well as in patients prone to allergic reactions, where as T1 W3D CE MR urography is at an advantage over T2 W 3D MR urography in imaging the kidney functionality, kidney dynamics measurement, it provides higher MRI signal intensity required for clear 3D reconstructions.

Increasing popularity of online banking systems instead of traditional branch networking requires understanding customer behaviors as users of such systems. This research aims to investigate online banking acceptance among Bosnian university students by considering system, user, acceptance and performance related factors by considering a new relationship between perceived system security and perceived system quality. According to the results, the users perceive that (1) online banking system is not secure and poorly qualified but useful and easy to use; (2) the users themselves are slightly capable of using the system; (3) they have intention to use the system but don’t use the system; and (4) they are slightly satisfied with the system and increase their benefits. The results also provide that all hypotheses except the relationship between perceived ease of use and intention to use are supported. Perceived System Security, as a new dimension, is found to have positive effect on Perceived System Quality. It can be implied that if the system is qualified and the users are self-efficient about using the system, they perceive the system as easy to use and useful. It is suggested that banks better take necessary steps to persuade their customers about the system security and usefulness in completing their tasks.

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the digestive tract and are generally asymptomatic. A 39-year-old female patient was hospitalized in 2012 at Clinical Department of Internal Medicine, Sestre milosrdnice University Hospital Center, for a focal hypodense irregular circular lesion located in segment III of the left hepatic lobe, accidentally found by ultrasonography and verified by computed tomography. The findings were also verified with nuclear magnetic resonance and esophagogastroduodenoscopy. A biopsy sample of the lesion was analyzed by histologic and immunohistochemical methods and identified as GIST. The patient underwent surgical operation (tumor excision with terminoterminal anastomosis created between the second segment of duodenum and jejunum and resection of liver segment III). The histopathologic findings matched GIST with a high probability of relapse according to the localization, size, mitotic activity and Ki-67 values. Therefore, therapy with imatinib at a dose of 400 mg/day was administered. Three years after the operation, the patient is still in remission.

Introduction: In recent years the quality of life of patients is very important in monitoring the treatment and therapeutic procedure success. It has become a significant factor in assessing the therapeutic procedure accomplishment, and for the first time the patient alone can access the success of the respective therapy. Cancer of the oral cavity is one of the most common cancers of the head and neck, and is one of the ten most common causes of death in the world. In the majority of cases, cancer of the oral cavity is detected in an advanced stage when therapeutic options are reduced, and the prognosis is much worse. Cancer of the oral cavity is 10 times more common in men. Assessment of quality of life should be an indicator of the multidisciplinary treatment success and it should point to areas in which the affected person requires support. Aim of the study: To examine the quality of life of patients with oral cavity cancer. Materials and methods: The study was conducted at the Clinic of Maxillofacial Surgery of the Clinical Center University of Sarajevo (CCUS), through a survey on patients with verified oral cavity cancer, questionnaire related to socio-demographic characteristics of the patients and the University of Washington Quality of Life Questionnaire (UW-QOL). The results were included in the database and statistically processed in the SPSS program, 19.0 version for Windows. Afterwards, the results were thoroughly analyzed and documented, presented in absolute numbers and statistical values using statistical indicators in simple and understandable tables and figures. Results: The study results showed that out of the total score of 100, the median value of quality of life of patients with oral cavity cancer, for the physical health component in the definition of quality was M=69.75 ±29.12 and for social-emotional health M=65.11 ± 27.47. Conclusion: This could be considered as satisfactory quality of life, in the sphere above half of the rating scale, although both values significantly deviate from the UW-QOL scale norm. Physical and socio-emotional health components are in a strong positive correlation, R2=0.750, p=0.0001.
