O objetivo do trabalho foi investigar associacoes entre as atitudes em relacao a matematica e o desempenho na disciplina de alunos do 6o ano do Ensino Fundamental. Participaram 37 escolares com idades entre 10 e 14 anos. Utilizou-se a Escala de Atitudes em Relacao a Matematica (EARM) para avaliar as atitudes dos alunos em relacao a disciplina. O desempenho na disciplina de Matematica foi investigado a partir da media das notas dos tres primeiros bimestres. As meninas apresentaram medias superiores aos meninos tanto na EARM quanto no desempenho. O teste de correlacao de Spearman apontou correlacao positiva e moderada. Quando tal associacao foi analisada separadamente, observou-se que nos meninos a correlacao foi fraca ( ro=0,343 ), enquanto que as meninas encontrou-se forte ( ro=0,758 ). Os achados evidenciam uma relacao positiva entre as atitudes em relacao a Matematica e o desempenho escolar na disciplina.

It has been noted that without the appropriate adverbial modification some passive participles are not acceptable in the attributive position in English: e.g. *a found suitcase, *a killed young man, *a built apartment block, as opposed to some passive participles that are not subject to this restriction: e.g. an abandoned village, a complicated man, the needed discipline. The assumption that identification of categorial status can be better seen at the level of larger constituents, has led us to propose some distributional diagnostic tests to confirm whether they retain their verbal force or have achieved their adjectival status in English, when used in the attributive position. Since their morphological form has not proved to be reliable for identification of their category, we have proposed to test them by classifying the types of adverbs enabling some of the passive participles to be used attributively. Given that the same adverbs can modify both, adjectives and verbs, we have focused on the classification of degree adverbs pre-modifying passive participles attributively used. The tests proposed in this paper may show that the open class degree adverbs that modify passive participles in both, attributive and predicative distribution do not fall into the single class but split up into the subclasses: degree adverbs/intensifiers and adverbs of measure/quantity modifying passive participles in attributive and predicative function, respectively. Since passive participles, too, may have different interpretation and either adjectival or verbal/passive reading when used as attributes, the open class degree adverbs are tested at the level of participial phrase used attributively within the NP. The examples were compared with the translation equivalents in BCS to see whether the same constraint affects passive attributes in BCS. Keywords: degree adverbs, intensifiers, adverbs of quantity/ measure, passive participles, complementary distribution

Introduction: Lumbar pain syndrome is the most common cause of temporary work disability in people under 45 years of age. The aim of this study was to detect the frequency of acute and chronic lumbar painsyndrome in people of both gender, different age structures, different occupations and in active working population, and to determine the efficiency of trunk stabilizing exercises in its treatment.Methods: We analyzed 27 patients with acute and 33 patients with chronic lumbar pain syndrome from 01.01.2010 to 31.12.2012 which undergone trunk stabilizing exercises. We evaluated and scored 0 to 5the condition of respondents before treatment and after the treatment.Research results: The mean score of condition of respondents with acute lumbar pain syndrome before therapy is 2.96, whereas after treatment is 4.71. The mean score of condition of respondents with chroniclumbar pain syndrome before therapy is 3.76, whereas after treatment is 4.63.Conclusion: Treatment with trunk stabilizing exercises performed in the clinic "Praxis” leads to improved scores of condition of respondents after treatment.

Introduction: The aim of this study is to determine prevalence of oral diseases and oral surgical procedures at Department of Oral Surgery, Faculty of Dental Medicine, University in Sarajevo.Methods: The current study is retrospective analysis of oral surgical procedures performed from January 2011 to December 2012 at Department of Oral Surgery, Faculty of Dental Medicine, University in Sarajevo. The data were statistically analyzed by T-test of independent samples and using Chi-squared test. P value lower than 0,001 was considered to be statistically significant.Results: A total of 1299 patients were included in study. The age range is from 18 to 84 years, with mean age ± SD= 35±15 years. There were 42 different clinical diagnoses, and 13 diagnoses appeared in more than 1% of all patients. Impacted and semi-impacted teeth, periapical lesions and retained roots are the most frequent diagnoses and represent 68% of all diagnoses. Embedded and impacted teeth (35%) and diseases of pulp and periapical tissues (31%) are the most frequent diagnoses with respect of ICD-10. Impacted teeth is the most common diagnosis and removal of impacted third molars is the most common oral surgical procedure.Conclusion: Study points out variety of dentoalveolar patology and complexity of dental health care that often requires interdisciplinary approach in order to achieve optimal outcome for patient.

Introduction: Injury during peripheral nerve blocks is relatively uncommon, but potentially devastating complication. Recent studies emphasized that location of needle insertion in relationship to the fascicles may be the predominant factor that determines the risk for neurologic complications. However, it is wellestablished that concentration of local anesthetic is also associated with the risk for injury. In this study, we examined the effect of location of injection and concentration of Ropivacaine on risk for neurologic complications. Our hypothesis is that location of the injection is more prognostic for occurrence of nerve injury than the concentration of Ropivacaine.Methods: In experimental design of the study fi fty Wistar rats were used and sciatic nerves were randomized to receive: Ropivacaine or 0.9% NaCl, either intraneurally or perineurally. Pressure data during application was acquired by using a manometer and was analyzed using software package BioBench. Neurologic examination was performed thought the following seven days, there after the rats were sacrificed while sciatic nerves were extracted for histological examination.Results: Independently of tested solution intraneural injections in most of cases resulted with high injection pressure, followed by obvious neurologic defi cit and microscopic destruction of peripheral nerves. Also, low injection pressure, applied either in perineural or intraneural extrafascicular area, resulted with transitory neurologic defi cit and without destruction of the nerve normal histological structure.Conclusions: The main mechanism which leads to neurologic injury combined with peripheral nerve blockade is intrafascicular injection. Higher concentrations of Ropivacaine during intrafascicular applications magnify nerve injury.

Introduction : One of the most important priorities in therapy is pain control. Therefore, many different groups of drugs are being used for this purpose, primarily opioid analgesics and non-steroidal anti-inflammatory drugs (NSAIDs). Opioid analgesic tramadol, by binding to specific receptors, modulates the perception and response to painful stimuli and inhibits transmitting and further processing of pain impulses. Lornoxicam, which belongs to the oxicam class of NSAIDs, is a non-selective cyclooxygenase inhibitor with strong analgesic and anti-inflammatory effects, and better tolerance profile. Preliminary research, which requires further verification, suggests that lornoxicam may be a better alternative or adjunctive therapy to opioid analgesics in the treatment of moderate to severe pain. The aim of this study was to investigate antinociceptive effects of lornoxicam, as well as the combination of lornoxicam with tramadol. Methods : Analgesic effect of combination of lornoxicam and tramadol or lornoxicam applied alone was examined on female albino mice, using a hot plate method. Measurements were made 30, 60, 90 and 120 minutes after intraperitoneal and subcutaneous administration, in dose of 10 mg/kg. Results: Combination of lornoxicam and tramadol, applied intraperitoneally, increases the threshold of sensitivity to painful stimuli, which was not the case with subcutaneous administration. Conclusions: Lornoxicam significantly increases analgesic effect when applied intraperitoneally in combination with tramadol. On the other hand, lornoxicam in combination with tramadol, did not increase the threshold of sensitivity to painful stimuli with significant difference, after subcutaneous administration

Introduction: A person’s response and functioning under condition of stress and confl ict is fundamentally different from its usual behavior. Aim: To point out what type of attitude toward the management of healthcare institutions is worth developing as well as to determine which psychological dimensions of employed the best refl ect the efficacy of the management.Methods: The study included a sample of 52 subjects employed at the Clinical center at University of Sarajevo and 64 subjects employed in Healthcare clinic in Sarajevo Canton. Survey method and a method of a theoretical analysis were used in the data collection and processing.Results: The study concluded that there is no statistically significant gender difference in attitude about the value of talent development at managerial level as a factor in development of attitude toward communicationin healthcare. We find t-value of 2,213 for the Clinical center at University of Sarajevo and 2,210 for Healthcare clinic in Sarajevo Canton.Conclusion: No statistically significant results have been found for any of the factors considered in the study with respect to the gender differences.

Introduction: Postponed recuperation from anesthesia can lead to different complications such as apnoea, aspiration of gastric content whit consequent development of aspiration pneumonia, laryngospasm, bradycardia, and hypoxia. Aim of this research was to determine infl uence of propofol, sevoflurane and isoflurane anesthesia on post anesthesia recovery rate.Methods: This was a prospective study; it included 90 patients hospitalized in period form October 2011 to may 2012 year, all patients included in the study underwent lumbar microdiscectomy surgery. Patients were randomly allocated to one of three groups: group 1: propofol maintained anesthesia, group 2: sevoflurane and group 3: isofl urane maintained anesthesia. Assessments of recovery rate were done 1, 5 and 10 minutes post extubation using White fast tracking scoring system.Results: Significant difference was observed only 1 minute after extubation (p=0,025) finding recovery rate to be superior in propofol group. Propofol group compared to inhaled anesthesia with sevoflurane group, shows significantly faster recovery from anesthesia only one minute after extubation (p=0,046). In comparison of propofol group and isofl urane anesthesia group, statistical significance was noticed one minute following extubation (p=0,008). Comparison of propofol group and inhaled anesthesia groups recovery rates were not significantly different at all times measured. When we were comparing sevoflurane and isoflurane anesthesia, recovery rates shoved no signifi cant statistical difference.Conclusions: Recovery rate evaluated by using White fast tracking scoring system was superior and with fewer complications in propofol maintained in comparison to sevoflurane and isoflurane maintained anesthesia only one minute post extubation, while after fifth and tenth minute difference was lost.

Introduction: Oxidative stress represents a pathophysiological mechanism lying behind occurrence of different acute and chronic diseases. Pregnancy, mainly due to placenta rich with mitochondria, is also being associated with the state of oxidative stress. Numerous markers have been proposed in order to test oxidative stress in pregnancy state, one of them being 8-isoprostane. The aim of this study was to analyse serum concentrations of 8-isoprostane as a possible oxidative stress marker in pregnancy.Methods: Serum concentrations of 8-isoprostane were measured in overall population of 84 woman, between 20 and 30 years of age. Tested population was divided in 2 groups: 42 pregnant woman were classifi ed as being either in the fi rst or second trimester of pregnancy. In the control group healthy nonpregnant women were included. Concentration of 8-isoprostane in serum was determined by commercial 8-isoprostane EIA test kit of Cayman Chemical Company, USA.Results: The 8-isoprostane levels were signifi cantly increased in pregnant women in relation to healthy non pregnant women (p<0.05). The 8-isoprostane levels were signifi cantly increased in second and third trimester of pregnancy (p<0.05).Conclusions: According to the obtained results, 8-isoprostane might be used as a possible marker of oxidative stress in pregnancy state, but not as a biomarker for the risk of complications development in pregnancy in analysed population.

Red mud - a waste product in alumina production, with its physical and chemical properties can be used as a pigment in the manufacture of concrete elements and façade colors. However, the consumption of red comparing to conventional inorganic oxide pigments is at least three times higher for achieving the same intensity of color. Since the rise in quatity of pigment in the concrete can lead to an increase in small fractions and the need for water in the concrete mixture, and deterioration concrete's technical properties (decrease of hardness, frost resistance, etc...), it is necessary to eliminate that negative effect with introduction of certain supplements in red bud. This can be achieved by adding a certain amount of hydrochloric acid for neutralization of alkaline mud solution and the creation of CaCl2 in the reaction with lime contained in it, which serves as accelerator of boning and hardening of concrete mixtures. Concrete materials colored with red mud treated in such manner, in addition to increased strength also have higher color intensity. Obtained concrete elements colored with the same quantity of red mud, without dosing and with dosing of various quantities of HCl will be photographed, and the photographs will be presented in the paper. The aim of this paper/work is a synthesis of cheap red pigment with satisfactory performance.
