The goal: The goal of this work was to give advantage to EUS as endoscopic method in diagnosis and following therapeutic treatment of pancreatic cancer in relation to radiological methods of CT and CTA. Material and Methods: The study included 49 patients, 20 women and 29 men hospitalized at the Clinic for gastroenterohepatology, due to suspicion on pancreatic cancer during observed 2 years period. All cancers were histologically and cytologically confirmed. The patients underwent ERCP as a mandatory part of staging and all patients underwent endoscopic ultrasound as well as CT or CT angiography. Results: Testing of differences was carried out using Fisher’s exact test in open-source software R. The following characteristics were tested: involvement of the blood vessels, lymph nodes, metastases, tumor size and duodenum infiltration. Results showed statistically significant difference at the 0.05 level for EUS, CT and CT angiography. Risk ratio showed that EUS is less effective in detecting infiltration of blood vessels within a malignant process then CTA where RR=0.52, CI 0.2–1.38, p-value=0.33. EUS and CTA are equal in the diagnosis of enlarged lymph nodes affected by malignancy where RR=1.3, CI 0.75–1.42, p-value=0.09. Comparison according to distant metastases showed that EUS is less effective compared to CT in approximately 30% of cases. In the diagnosis of duodenal infiltration EUS is in 5% of cases less accurate than the CT with the RR=0.95, CI 0.27–3.32, p-value=0.76, but the CTA method is more efficient because the comparison of EUS and CTA showed RR=12.52, CI 0.2–1.38, p-value=0.33. EUS as a diagnostic method is dominant in determining the size of malignant lesions located in the pancreas as compared to CT and CTA. Conclusion: EUS as endoscopic method compared to CT and CTA is one of the more invasive methods of examination but due to its ability to be performed immediately, to locate a changes smaller than 5 mm and the target biopsy option, to measure the change and that in many cases determine the relationship of malignant lesions with blood vessels, along with visualization of the surrounding lymph nodes and metastases in neighboring organs, we may give this method an advantage over other methods in the preoperative staging of patients with pancreatic cancer.

The vulnerability results of groundwaterbodies of southeastern Bosnia are shown in this paper. On the examined area 27 groundwater bodies were extracted, where 12 groundwaterbodies are in rocks with intergranular porosity and 15 groundwaterbodies are in rocks with karst-fissure porosity. All of the groundwater bodies were analysed through DRASTIC, GLA, PI and EPIK vulnerability determination methods, where the gained results are presented tabular. Depending on the porosity type, the vulnerability determination methods were used. So for intergranular groundwaterbodies the best results were gained by DRASTIC and GLA methods, while for the karst-fissure groundwater bodies the best results were gained by the EPIK method, which is the implementation of PI method.

SUMMARY Qualitative characteristics of bauxite deposit „Ostrelj“ are defined through extensive laboratory testing of chemical and mineralogical-petrographic composition, and geomechanical characteristics. Chemical composition has shown that it is a relative poor bauxite with low Al/Si module (2,28). Low values of Al/Si module are result of lower Al2O3 concentration (48 %), and higher SiO2 concentration (21 %), what these bauxites define as high silicic or »acidic«. Identified are increased concentrations of larger number of analyzed trace elements (B, Co, Cr, Li, Mn, Ni, Sn, V, Zn) comparing to the medium content in the Earth's crust. Mineralogical composition, structure and texture are uniform. Holders of Al mineralization are bemite and diaspor (to a lesser extent) as crypto-crystalline phases of rock matrix. Lower Cretaceous age (K1) of roof layers over bauxite deposit is paleontologicaly documented, while in the bauxite any fossils are not registrated. Values of geomechanical paramers of layers under and over bauxite is uniform. In bauxite value of compressive strength is increased, which is equivalent to chemical and mineralogical composition, and structural and textural characteristics of tested bauxite samples.

UDK: 630*52/*56:528.8(234.422 Igman) Information about quantitative and qualitative forest attributes are the base for successful forest planning and management. Forest inventories collect number of data used for different estimations from large (management unit level) to small (forest stand) scales. Then, control sampling has to be done in order to confirm regularity of terrestrial work. Such sample becomes data source too.  Recent approach for forest characterization includes all available information as sources for additional non-standard insight. Here were used available data about wood volume and increment from control sample for high forest on mountain Igman. Also, recent Landsat TM image from vegetation period was available and used in this research. Here is applied k nearest neighbor’s estimation method. Five nearest neighbors and Euclidian distance is chosen for estimation and mapping. Biases for all forest attributes were non-significant. Obtain results show non significant differences between means and observed and estimated distributions of wood volume and increment. It is estimated higher mean wood volume and increment of broadleaves while means for conifers and totals are lower. That higher wood volume and increment is estimated in all diameter classes for broadleaves while lower quantities are estimated for conifers. Spatial mapping presents distribution of wood volume and increment respecting variability of vegetation in high forest on Igman.

We present a minimalist social robot that relies on long timeseries of low resolution data such as mechanical vibration, temperature, lighting, sounds and collisions. Our goal is to develop an experimental system for growing socially situated robotic agents whose behavioral repertoire is subsumed by the social order of the space. To get there we are designing robots that use their simple sensors and motion feedback routines to recognize different classes of human activity and then associate to each class a range of appropriate behaviors. We use the Katie Family of robots, built on the iRobot Create platform, an Arduino Uno, and a Raspberry Pi. We describe its sensor abilities and exploratory tests that allow us to develop hypotheses about what objects (sensor data) correspond to something known and observable by a human subject. We use machine learning methods to classify three social scenarios from over a hundred experiments, demonstrating that it is possible to detect social situations with high accuracy, using the low-resolution sensors from our minimalist robot.

UDK: 582.632.1:581.45(497.6) Natural interspecies hybrids of black (Alnus glutinosa (L.) Gaertn) and grey (A. incana (L.) Moench) alder are not frequent in nature but they are registered, and according to modern systematic nomenclature are classified within nothospecies A. × pubescens Tausch.. Since the presence of spontaneous intermediate forms of the genus Alnus in Bosnia and Herzegovina is insufficiently explored, the first results of comparative morphological analysis (seven leaf’s characters) of black and grey alder and their hybrids are given in this study. About 10% of hybrid individuals were present in the studied sympatric populations, and they had more heterogeneous leaves than parental species. Good diagnostic characters showed intermediate values in comparison to the parental species, which are: number of pairs of lateral veins, angle from the top of the leaflet to the top of the upper 3rd nerve, and distance from the top of the leaflet to the top of the upper 3rd vein. According to analyzed characters, hybrids either hold intermediate positions between the parental species or are closer to the maternal species (A. incana). Three new findings of nothospecies A. × pubescens for Flora B&H are rivers’ localities Drinjača near Kladanj, Turbe near Travnik, and Stavnja near Vareš. Due to the low frequency of observed individuals of A. x pubescens, they are vulnerable and require special measures of protection and biodiversity conservation activities of autochthonous gene pool, it is necessary to determine the actual state in all previously published hybrid complexes’ findings and expand researches in B&H in the coming period.

Abstract. Raman microspectroscopy and quantitative backscattered electron imaging (qBEI) of bone are powerful tools to investigate bone material properties. Both methods provide information on the degree of bone matrix mineralization. However, a head-to-head comparison of these outcomes from identical bone areas has not been performed to date. In femoral midshaft cross sections of three women, 99 regions (20×20  μm2) were selected inside osteons and interstitial bone covering a wide range of matrix mineralization. As the focus of this study was only on regions undergoing secondary mineralization, zones exhibiting a distinct gradient in mineral content close to the mineralization front were excluded. The same regions were measured by both methods. We found a linear correlation (R2=0.75) between mineral/matrix as measured by Raman spectroscopy and the wt. %Mineral/(100-wt. %Mineral) as obtained by qBEI, in good agreement with theoretical estimations. The observed deviations of single values from the linear regression line were determined to reflect biological heterogeneities. The data of this study demonstrate the good correspondence between Raman and qBEI outcomes in describing tissue mineralization. The obtained correlation is likely sensitive to changes in bone tissue composition, providing an approach to detect potential deviations from normal bone.

ABSTRACT Introduction: Many factors concomitantly influence the quality of life of patients with schizophrenia in a long-stay psychiatric facility. Th e appropriate selection of antipsychotics and the intensity of their adverse effects exert a significant influence on the quality of life of these patients. Th e aim of this study was to identify the influence of antipsychotic-related factors on the quality of life of patients with schizophrenia. Methods: Th e study included 102 beneficiaries at the Institute for Accommodation of Adults “Male Pčelice” in Kragujevac. Th e patients were interviewed on in one day using the questionnaire issued by the World Health Organization. The specified data were obtained from the health files of the beneficiaries. We performed a comparison between patients receiving only atypical antipsychotics, typical antipsychotics or a combination thereof. Results: Th e patients who were receiving only atypical antipsychotics demonstrated better physical health quality of life scores in comparison to those who received combined antipsychotics (77.14 vs. 68.57; U = 332.0; p = 0.02). A statistically significant difference in the mental health quality of life domain was observed between groups of patients receiving various antipsychotic treatments (31.96 vs. 55.27 vs. 49.46; c2 = 7.02; p = 0.03). Conclusion: Patients in a long-stay psychiatric facility who received atypical antipsychotics demonstrated a better quality of life in comparison to those who received typical antipsychotics, possibly due to the superior safety profile of atypical antipsychotics and a greater feeling of individual contentment. SAŽETAK Uvod: Na kvalitet života osoba koje boluju od shizofrenije utiče mnogo faktora istovremeno. Kod pacijenata u institucionalnom smeštaju adekvatan izbor antipsihotika i intezitet neželjenih dejstva lekova ima veliki uticaj na kvalitet života ovih pacijenata. Cilj ove studije je bio da se utvrdi uticaj faktora vezanih za antipsihotike na kvalitet života pacijenata koji boluju od shizofrenije. Metode: Istraživanjem je obuhvaćeno ukupno 102 korisnika Zavoda za smeštaj odraslih lica „Male Pčelice” Kragujevac. Korisnici su ispitani u samo jednom izabranom danu korišćenjem upitnika Svetske zdravstvene organizacije. Određeni podaci su prikupljeni iz zdravstvenih kartona korisnika. Poređene su grupe korisnika koji koriste samo apitičan ili tipičan antipsihotik ili kombinaciju ove dve grupe antipsihotika. Rezultati: Korisnici koji koriste samo atipičan antipsihotik imaju bolji skor fi zičkog zdravlja od korisnika koji koriste kombinaciju antipsihotika (77,14 vs. 68,57; U = 332,0; p = 0,02). Postoji statistički značajna razlika u skoru domena psihičkog zdravlja u zavisnosti od grupe antipsihotika koji je korisniku propisan (31,96 vs. 55,27 vs. 49,46; c2 = 7,02; p = 0,03). Zaključak: Korisnici ustanove za dugotrajan smeštaj psihijatrijskih bolesnika koji primaju apitične antipsihotike imaju bolji kvalitet života u odnosu na pacijente koji primaju tipične antipsihotike, verovatno zbog manje izraženih neželjenih dejstava atipičnih antipsihotika i boljeg osećaja subjektivnog zadovoljstva.
