Abstract Despite numerous scholarly attempts, there is a lack of consensus regarding the relevance of various factors influencing consumer’s intention to purchase organic food. The purpose of this study is to asses the impact of subjective and personal norms on consumer attitude toward buying organic food. Moreover, this study aims to explore the moderating role of contextual factors - product knowledge and consumer scepticism on the norms- attitude link. Data were collected through an online survey on a sample of 212 organic food buyers in Bosnia and Herzegovina. Moderated regression analysis was used to test the hypothesized relations between the constructs of interest. Findings indicate the subjective and personal norms are positively and significantly related to consumer attitude toward organic food purchases. Also, our findings revealed that product knowledge strengthens the subjective norms-attitude relationship, while consumer scepticism toward organic food claims weakens the subjective norms-attitude link. This study informs producers, marketers, and policy-makers about the relative importance of norms, scepticism, and knowledge in the context of organic food consumption.

Electrical measurement of degradation in metal films induced by high thermo-mechanical stress is not possible. Therefore, different imaging methods are used in practice to visualize the changes in material microstructure. In this work, SEM (Scanning Electron Microscopy) cross section images of the metal layer of interest that illustrate the fatigue induced degradation and material microstructure are analyzed. We propose an unsupervised algorithm for detection and quantitative assessment of the damage in mentioned images. In the first stage of the algorithm, the metal layer of interest is extracted from the background using k-Means method. In the second stage, the non-local means (NL-means) denoising method with automatically computed standard noise deviation followed by post-processing and k-Means is used to detect the damage patterns. Visual and quantitative evaluation of results reveals that the algorithm provides robust and plausible results.

The problem that is being addressed in this paper is to improve the services provided by company and achieve better communication between companies in the supply chain. Therefore, a qualitative assessment of service has been required. This service is characterized by a group of parameters, which are often inaccurately estimated values, as well as their importance for the evaluation system. This is often the result of assessor ́s uncertainty, variability of conditions, etc. Therefore, in the context of AM4SCM (Adaptive Model for Supply Chain Management) a mathematical model for evaluating the quality of services has been developed (FAM4QS Fuzzy Aggregation Method for Quality Service) which is based on the fuzzy arithmetic. Selection of different values for the degrees of fuzzy power mean, which are used for evaluation of parameters or groups of parameters of the system and the service, contributes to a better assessment and it is due to the varying nature of the parameters. The observed model was simulated on 17 supply chains on the territory of the Republic of Serbia. Service quality assessment is carried out based on data from the user requirements participants of supply chains binding the so-called fuzzy aggregation function.

The daily requirements and needs imposed on the executors of logistics services imply the need for a higher level of quality. In this, the proper execution of all sustainability processes and activities plays an important role. In this paper, a new methodology for improving the measurement of the quality of the service consisting of three phases has been developed. The first phase is the application of the Delphi method to determine the quality dimension ranking. After that, in the second phase, using the FUCOM (full consistency method), we determined the weight coefficients of the quality dimensions. The third phase represents determining the level of quality using the SERVQUAL (service quality) model, or the difference between the established gaps. The new methodology considers the assessment of the quality dimensions of a large number of participants (customers), on the one hand, and experts’ assessments on the other hand. The methodology was verified through the research carried out in an express post company. After processing and analyzing the collected data, the Cronbach alpha coefficient for each dimension of the SERVQUAL model for determining the reliability of the response was calculated. To determine the validity of the results and the developed methodology, an extensive statistical analysis (ANOVA, Duncan, Signum, and chi square tests) was carried out. The integration of certain methods and models into the new methodology has demonstrated greater objectivity and more precise results in determining the level of quality of sustainability processes and activities.

This paper shows a method to determine unknown angular accelerations of driving members of a planar mechanism with multiple degrees of freedom via partial mechanism reduction, assuming that driving loads are known for those driving members. Besides the partial reduction of mechanism, here we use the analysis of primary and secondary accelerations, as well as the principle of virtual displacements (virtual work). Using this method, a set of decoupled equations is obtained, which is an advantage when compared to classical methods, such as an application of generalized laws of dynamics, which result in a set of equations that are coupled. As an illustration of how to use the described method, an example is shown.

Abstract The main goal of this paper is to examine the influence of macro factors and the degree of the exchange rate pass-through (ERPT) on aggregate and disaggregate import prices of the industrial sectors in the short- and long-run. The study is based on a model used by Campa and Goldberg (2002) and Campa et al. (2005). The ERPT is determined by applying the single equation and the cointegration approach (autoregressive distributed lag model [ARDL]), vector decomposition, and data over the period from 2002Q1 to 2016Q4. In the long-run, the ERPT is complete for the aggregate import and for the industrial sector beverages and tobacco. In the short-run, the ERPT is incomplete for the aggregate import and for majority of industrial sectors. Further, we have discovered that the degree of the ERPT is higher with heterogeneous products than with homogeneous products. Due to the inaccessibility of data for micro factors, we were not able to determine their effect on import prices. The results of our research can help economic policymakers to create adequate measures in the field of economic policies that will improve the competitiveness of the economy. Finally, this paper identified the effect of the volatility degree of the ERPT on the disaggregate import prices of industrial sectors that has not been sufficiently explored so far.

Introduction: The role of Radio frequent Generator (RF) has been extended from simple tumor ablation to routine hepatic resection. RF energy precoagulates the tissue and thus allows the closure of small blood vessels and bile ducts. The development of surgical techniques and modern technological advances have enabled liver resections to be significantly surgically better controlled in the sense of bleeding, and are more successful and safer for patients. The RF generator has its advantages and disadvantages and as such can be equally used in resective liver surgery. Aim: Display the intraoperative and postoperative complications among patients that had been subjected to liver resection using a RF generator (RF resection), compared to those that had been subjected to liver resection without the use of RF generators (classical liver resection methods of CC resection). Material and methods: The study included 60 patients of both sexes which had resective operative surgery or metastasectomy on the liver due to the basic process. The study was conducted at the Clinic for General and Abdominal Surgery of the Clinical Center of the University of Sarajevo in a four-year period. The study was designed as a comparative study of outcome and postoperative complications of surgical treatment, i.e. resective liver interventions using two operating techniques (RF–liver resection and Classical resection techniques on the liver). Results: The highest number of surgical procedures was due to colorectal cancer. A slightly smaller number was performed due to primary liver cancer and gallbladder cancer. The highest number of surgical interventions remain on non-anatomic resections. Smaller number remains to large resective operations. The length of hospitalization was significantly correlated with blood loss (r = 713 p = 0,000) and the average hospitalization time ranged from 10.5 to 53.3 days. Conclusion: We have shown that the use of RF generators does not significantly reduce intraoperative and postoperative complications. There is a justification for using both techniques for resection on the liver. The resective liver operation depends mostly on the personal stance and the surgeons training.

Introduction: The increase in the percentage of the Cesarean sections has got an important place in determination of modern obstetrics. The evaluation of that needs actual, modern opinion for obstetrics and transformation actual obstetric science than investigating the best situation for the mother and child in the actual moment. All medical, organizational, economic and ethical capacities with support of modern diagnostic and therapeutic procedures present a reason for the access in modern obstetrics. It takes the descriptive and analytic method at work. In our country the percentage of the Caesarean section is 15% (according to WHO data), with large variations in frequency depending on the writer and the investigated time. Aim: To investigate the prevalence of Cesarean section in Bosnia and Herzegovina until 2017. Patients and Methods: In our investigation made prospective and target analysis is investigated at 2017 as a target year. Sources are: patient charts, notes and charts of new born. Group A presents number investigated patients with made Cesarean section in time at one year (2017) in General hospital „Prim.dr A.Nakaš“. Group B presents control group with identical number of deliveries with Cesarean section in 2007 in General hospital „Prim.dr A. Nakaš“ with all variables who detected in investigation group. Results: Analysis the number of deliveries finished Cesarean section in time from 2007 to 2017 in General hospital „Prim.dr Abdulah Nakaš “Sarajevo presents augmentation frequency from 15,5 % in 2007 year to 21,7 % in 2011; smaller number in 2012 to 20,3% and finally 22.9% in 2017 for all deliveries. Conclusion: Our investigation shows an important number of Cesarean section and is still working because of clearer obstetric indication but they make a vital indication for the mother and baby. It worries percent of poorly described indications, that are something important for the comfort of doctor and any patients that wants natural delivery. It worries the public because the more important short term and long-term unwanted effects; Cesarean delivery in correlation with augmentation of this operation.

Low-velocity layers within the crust can indicate the presence of melt and lithologic differences with implications for crustal composition and formation. Seismic wave conversions and reverberations across the base of the crust or intracrustal discontinuities, analysed using the receiver function method, can be used to constrain crustal layering. This is commonly accomplished by inverting receiver functions jointly with surface wave dispersion. Recently, the proliferation of model-space search approaches has made this technique a workhorse of crustal seismology. We show that reverberations from shallow layers such as sedimentary basins produce spurious low-velocity zones when inverted for crustal structure with surface wave data of insufficiently high frequency. Therefore, reports of such layers in the literature based on inversions using receiver function data should be re-evaluated. We demonstrate that a simple resonance-removal filter can suppress these effects and yield reliable estimates of crustal structure, and advocate for its use in receiver-function based inversions.
