UDK: 595.768.1:582.475(234.422 Zvijezda) Bark beetles are the most important pests of the coniferous forests. Although they are considered to be a secondary pest, they are becoming the primary pests that attack healthy trees. One of the important spruce bark beetle is the Pityogenes chalcographus (L.) - a small spruce beetle. The research was conducted in the municipality of Vareš, on three locations: Ponikva, Pobrin Han, Doli. The active period of the bark beetle for development began in the last decade of April. P. chalcographus in the field of research had two generations. For the development of generations it took between 12 and 13 weeks. Weather conditions in the object of research did not allow the completion of the second generation. The activity of the bark beetle ends in mid-September. When we talk about the characteristics of wood material which prefers small bark beetle of spruce, we can say that he prefers to inhabit thinner parts of trunk with thin and smooth rind. In the object of research for monitoring of population of bark beetle P. chalcographus was used trap trees. As a measure to combat the small spruce bark beetles are strongly advised in due time, autumn and winter, remove the dried trees and trees with drilled bark beetles. Maintenance and establishment of forest order to reduce the amount of wood material suitable for the settlement of bark beetles.

This paper investigates the performance of the BCH encoder and decoder for different error-correcting capabilities. The focus is on BCH codes of length 255. The motivation for this research is a project where data symbols of this length are transmitted over an error-prone wireless channel. The paper presents a mathematical introduction into encoding for cyclic codes and decoding of the BCH code. The code was implemented in both software and hardware and the performance and cost of both implementations were measured for different code parameters.

Digital printing has matured and it is now present in daily production. This is true for both the large format inkjet printing and digital commercial printing (with toner based and increasingly with ink jet technique). In the graphic arts industry in particular the latter use case shows tremendous growth figures where small and medium run lengths are taken over increasingly from the offset market (Kraushaar, 2010). As digital printing industry grows every day a lot of work has been done in improving and developing new technologies and products. This increased growth demands higher level of quality assessment in order to be able to compare different products and technologies and evaluate them (Pedersen et al., 2011). Most production digital printing processes depend on the use of certified paper to perform to their best capacity. Any adjustments that need to be made to the actual press require the intervention of technical support personnel other than the press operator (Chung & Rees, 2007). Print quality is very important in each printing technology, and also for digital printing (Rilovski et al., 2012). A common way for analyzing the print quality is to quantitatively assess image color and tone value reproduction using corresponding measuring device. This way of analyzing print quality is easy, since tone and color are easily perceptible, but they are not enough for determining print quality (Dhopade, 2009; Kiurski & Oros, 2012). Several experiments proved that print quality is not a monotonic function of hue, saturation and brightness (Fedorovskaya, Ridder & Blommaert, 1997; Pedersen et al., 2009). Quantitative print quality assessment depends on a number of quality attributes (Pedersen et al., 2011; Rilovski et al., 2012). There are several of them such as contrast, sharpness, macro-uniformity, etc., which are not associated with tone and color but have considerable influence on print quality. They are directly connected with line and dot quality, which are structural elements of any image (Dhopade, 2009). So far many researches have been done that confirmed the importance of different quality attributes, but there is no overall agreement which of them are most important (Pedersen et al., 2011; Rilovski et al., 2012). One of the reason is multidimensionality and complexity of image quality (Pedersen et al., 2011).

Introduction: Gastric cancer is the second most important neoplasm in the world. Surgical resection is the treatment of choice for gastric cancer, and recognized by the International Union against Cancer (International Union Against Cancer – UICC) TNM classification of the parameters of the tumor and lymph node. Prognostic factors related to characteristics of the tumor by histopathologic findings have an impact on the planning of the operation. According to the results of most studies it is possible to predict survival and recurrence based on histological type and TNM classification of tumors on the one hand and the surgical procedure on the other. Aim: The aim of the research was to analyze prognostic factors that influenced the frequency of recurrence in gastric surgery patients. Patients and methods: The five year study covered a population of 100 treated patients of adenocarcinoma of the stomach at the Department of Surgery, University Clinical Center Tuzla. The first group were characteristics of tumors in patients with gastric adenocarcinoma. Lymphadenectomy and splenectomy, types of surgery were the second group of prognostic factors. Results: Histological type and TNM stage of tumor as prognostic factors had a significant impact on local tumor recurrence. The type of surgery had no statistically significant value for tumor recurrence (p = 0.7520). Conclusion: Statistical analysis of prognostic factors related to histopathologic characteristics of tumors and the type of surgery gave the results that had an impact on recurrence in gastric surgery patients. The most important prognostic factors were TNM stage of tumor and histological type of tumor that influenced the incidence of recurrence.

UDK: 582.675.1:575(497.6) Helleborus multifidus Vis. is endemic Illyric-Adriatic species with distribution range in Italy, Slovenia, Croatia, Bosnia and Herzegovina, Montenegro and Albania. Although few studies reported different taxonomic categories for H. multifidus, this one is the first using molecular-genetic markers (trnL region and matK of chloroplast DNA and nuclear ITS1 and ITS2 region) for genetic characterization of H. multifidus presented at three localites in Bosnia and Herzegovina. The results revealed that PCR-RFLP on trnL intron was not informative for testing inter- or intrapopulation diversity. Contrary, analysis of matK, ITS1 and ITS2 sequences showed differences between populations from Trebinje region and Kupreško polje, pointing to the need to include additional analyses in order to confirm these findings.

Introduction: Anemia occurs in 60% to 80 % of patients with newly diagnosed myeloma multiplex (MM). The cause of anemia in MM is probably multi factorial and involved among the others hepcidin and some cytokines, especially interleukine-6. Anemia in MM is one of the risk factor used in Durie-Salmon classification for staging and prognostic score. Treatment options are set according to this score with most significant impact on survival. Aim: To estimate baseline level of serum hepcidin, IL-6 and iron metabolism markers in anemic MM patients, possible role of hepcidin and its interaction with IL-6. Methods: 27 patients with newly diagnosed MM were enrolled in this observational, prospective study and age, gender matched 60 healthy controls. Erythrocyte count, hemoglobin, serum hepcidin, interleukin-6, iron, ferritin and transferrin were measured. Results: Anemia was diagnosed in 70% of MM patients. Serum hepcidin was significantly higher in MM group (55.5 ng/mL) than in control 5.9 ng/mL (p=0000). In myeloma patients serum IL-6 was 3.59 pg/mL, anemic 3.80 pg/mL, non-anemic 0.33 pg/mL, without significant difference. It was not found significant correlation between hepcidin and IL-6 in anemic myeloma patients. Conclusion: High level of hepcidin probably causes anemia in MM but its high expression is not due only to IL-6.

Introduction: Cardiovascular diseases are the leading cause of death in most countries. The aim was to examine the quality of life and to determine the differences in the quality of life in patients one year after myocardial infarction and the relationship between quality of life and echocardiographic parameters in these patients. Material and Methods: The research was a prospective, clinical, epidemiological study and was conducted at the Clinic of Cardiology, University Clinical Center Sarajevo (UCCS). The research was conducted on a sample of 160 patients who had acute myocardial infarction, which are based on the therapeutic procedures divided into four groups. The average age in the total sample was 54.9±8.8 years (range 37-76 years). The research was conducted one year after myocardial infarction (I group of subjects) or 12 months after PCI therapeutic procedures (II and III group of respondents) or coronary artery bypass surgery (IV group of respondents). Results: Comparison of the mean scores of scales in SF-36 questionnaire showed that the highest total score had patients in the group II 67.3±15.2, and the lowest in the group I 57.8±21.4. The increase in ejection fraction leads to a statistically significant increase in quality of life scores at all subscales, in all groups, so that EF has the greatest impact on the quality of life in all respondents. Statistically significant differences in the effects of mitral regurgitation in particular groups have been recorded only in the case of the mental health scale. Conclusions: Ejection fraction has the greatest impact on the quality of life in all patients, regardless of the type of medical treatment.

Introduction: The objective of this study was to determine the oral health condition Down syndrome (DS) adults in Bosnia and Herzegovina, by analyzing oral health of Down syndrome individuals in two largest regions, Sarajevo and Tuzla Canton. Patients and Methods: Caries and oral health status of 33 Down syndrome adults aged 19-45 years were examined and assessed according WHO 1997 criteria. Results: The mean DMFT index is 15,96±8,08. The analysis of oral hygiene of Down syndrome children by using the debris index, is found that 42,4% have very good oral hygiene, 21,2% respondents have good oral hygiene, 27,3% are with poor oral hygiene, while the very poor hygiene have 9,1% subjects. The Value of CPI index is 0,82.

Abstract Low birth weight newborns (≤1500 grams) are at a high risk of acquiring hospital infections due to the immaturity of the immune system, lack of efficient structural barriers, and an incomplete development of endogenous microbial flora. The aim of this study was to reveal the potential risk factors for hospital-acquired pneumonia in low birth weight newborns. This study was a prospective cohort design with a nested case-control study and was conducted between January 1st, 2012 and June 30th, 2015 at the Neonatology Department, Clinical Centre Kragujevac, Serbia. There were 1140 newborns hospitalized at the Neonatology Department for longer than 48 hours during the study period, and 169 of them (14.82%) weighed less than 1500 grams at birth. In total, 73 (43.19%) newborns with low birth weights developed HIs. The most prevalent HI was hospital pneumonia (n=64, 87.67%). Although univariate analyses identified many risk factors with a significant influence on the occurrence of hospital pneumonia, multivariate analysis identified only the following two independent risk factors for hospital pneumonia in newborns with birth weights below 1500 grams: mechanical ventilation (p=0.003, OR=68.893, 95% CI=4.285-1107.699) and longer hospitalization (p=0.003, OR=1.052, 95% CI=1.017-1.088). Almost all of the pathogens isolated from the patients with pneumonia were gram-negative bacteria (98.50%). More than half of all of the isolates were Acinetobacter spp (37.50%) and Enterobacter spp (18.75%). Our study showed that mechanical ventilation and prolonged hospitalization were significant risk factors for the development of hospital pneumonia in newborns with birth weights below 1500 grams.
