The main goal of the paper is to determine underlying dimensions of perceived quality of maritime tourist destination´s offer. Using the purposive sampling technique, data collection was carried out from January to August 2019 in the destinations of Opatija Riviera, yielding a sample of 155 valid responses. To gain better understanding of underlying dimensions of perceived quality of maritime tourist destination´s offer, we, primarily, use exploratory factor analysis. The research findings have revealed that organization of a destination, gastronomic offer, natural resources, traffic infrastructure, destination´s cultural resources, accommodation capacities, attractions and sports activities are the main factors of perceived quality of maritime tourist destination´s offer.

In the period between April 6, 1992 and December 14, 1995, an estimated 102,622 people were found to have died due to war-related causes in armed conflicts in Bosnia and Herzegovina. Of those killed in the war in Bosnia and Herzegovina it is estimated that 54% were civilians. The war profoundly affected the civilian population, which was subjected to mass killings, the systemic use of rape and sexual violence, and the physical and psychological torture inside concentration camps. This case study paper has four aims. First, it highlights the complexity and severity of the traumatic psychological effects of the war in Bosnia and Herzegovina on its citizens, including the effects of the war on the generation born during or shortly after the war. Second, the paper proposes a heuristic in the form of a broader theoretical approach; an ecological analysis of human development (Bronfenbrenner, 1989). This approach aims to provide a framework for research and the development of intervention strategies for the adolescent children of adult war survivors who have been affected by war-related trauma. Third, the paper presents a case vignette of an adolescent to demonstrate the application of the ecological framework to clinical practice with adolescents. Finally, we explore how the current cultural, political, and societal realities in Bosnia and Herzegovina affect the population in general and the children of war survivors in particular. The transition from a state of war to peace is a long and continuous process with residual effects of violent conflicts permeating the broader society and its inhabitants, even after the war’s official end over 23 years ago. The authors argue that roles of psychologists and other mental health providers should expand beyond traditional focus on intrapsychic problems. Rather, effective treatment strategies should also include recognition of and attenuation of the larger systemic stressors that patients experience on daily basis. This could be accomplished through collaboration among psychologists and patients, patients’ families, teachers, and community members, all of whom directly or indirectly affect patients’ treatment outcomes.

Although the most prominent material in contemporary construction practice due to its obvious advantages, concrete possesses a number of drawbacks. One of the advantageous principles for decades is to enable a large scale on-site application of this material with acceptable properties, needed to withstand specific conditions. A concept of 3d printing concrete presents a promising ground for further improvement of this principle. While maintaining as much as possible of the prerequisite and common properties to answer the construction demands, this material has to evolve as much as possible to fulfill the 3d concept, which would, in turn, pave a way for the next level of its construction applications. This paper presents the main principles of 3d printing concrete, by discussing the main goals and the drawbacks that have to be solved prior to wider application. Also, one specific facility- wind tower will be reconsidered as a potentially promising ground for this old construction material dressed in a new suit.

Due to the Portland cement chemical reaction, which always takes place in a hardening concrete, a certain amount of heat is released. This heat should be quantified, as it can harm or aid the concrete itself, depending on the concrete components, structure element, ambient and building site conditions. There are number of possible setups for the monitoring of heat of hydration, two of which have been applied in the case presented in this paper. Four concretes were monitored with the use of the two stated techniques for 24 hours. First technique used is thermo-vision camera which monitored the surface, and the second is thermosensor - used for monitoring of interior of fresh concrete hardening mass. The potential of the applied setup lays in the ease of installation, low price, and possibilities of mass application, which could substantially aid the monitoring and prevent concrete failure.

: This paper presents a research conducted as part of development of the graduation thesis entitled: "Hydraulic numerical analysis of groundwater in the left hinterland of the Mostar hydroelectric power plant dam", which was developed and successfully defended at the Faculty of Civil Engineering, University of Mostar in 2020. The Mostar hydroelectric power plant, in tandem with the Salakovac HPP, levels the flows in the downstream course of the Neretva River. In the area around the embankment and the diaphragm wall, there are indications of filtration deformations of soil, and development of dominant directions of groundwater flows. The paper examines the area of the left hinterland of the Mostar hydroelectric power plant dam in the MAGNET 4 WATER program, and compares the obtained results with the existing verified results from the DHI WASY FEFLOW program as well as the field results. It was concluded that the spatial model is suitable for further research and analyses, e.g. for monitoring groundwater flows in the area, and for the analysis of risks of contaminant transport underground the left hinterland of HPP Mostar.

Cilj ovoga rada preispitivanje je dominantnih historiografskih predodžbi o transformacijskim procesima u ekonomskoj povijesti Osmanskoga Carstva te obrada nepoznatih aspekata osmanskih financijskih mjera koje su na području Bosanskoga ejaleta poduzete u prvih nekoliko godina nakon Karlovačkoga mira (1699.). Rad pokazuje kompleksnost osmanske strategije u borbi sa stvarnim i percipiranim učincima gospodarske krize koju je na zapadnoj periferiji svijeta islama izazvalo dugotrajno ratovanje s koalicijom Svete lige. Nastoji se pokazati da je za potpunije razumijevanje osmanskih transformacijskih procesa potrebno temeljitije ispitati mjere koje je vlast provodila u pograničnim provincijama. Kao primjer tih mjera istaknuto je trajno oslobađanje cijeloga Bosanskog ejaleta od poreza bedel-i nüzûl, namijenjenog za opskrbu i financiranje vojske. Ukazano je i na značenje krupnih promjena u režimu ubiranja državnih prihoda kao što je ukidanje „vlaških poreza” i odsjekom određenih novčanih podavanja u znatnom dijelu osmanskoga agrarnog gospodarstva u Bosni te prijelaz na režim naturalne desetine. Analizirani su uzroci koji su doveli do tih mjera, njihove dugoročne posljedice za osmanske financije, život lokalnoga stanovništva i gospodarstvo. Zaključci izneseni u radu zasnovani su na analizi neobjavljene financijske građe iz osmanskih arhiva.

Regulation Plan for the historic town area of Mostar includes major aspects of preservation and development of historic town zones. Provisions of the Regulation Plan pertain to use of land and buildings, aiming to preserve and revive the traditional uses and protect the natural characteristics of the area [8]. In this respect, the historic area of the town of Mostar has been divided into ten zones according to the use of land and structures, and Zone 8 covers Neretva as a protected riverside zone. The study aimed to define causes and state of weathering, damage and stability of rocks, then to define the existing state in terms of geological structure, and visit the most critical sections that require improvement.

: This paper presents the results of statistical analysis of collected data on the characteristics of envelope elements, as one of the key factors influencing energy consumption and costs, of school buildings (primary and secondary schools) located in the south region of the Federation of Bosnia and Herzegovina (SR FBiH). The shares of the areas of walls, floors, ceilings and openings in the total area of the envelope, as well as thermal characteristics expressed through the heat transfer coefficient or U-value, were analyzed. This research was conducted by collecting data from detailed energy audit documents on a sample of 47 school buildings located in SR FBiH, which has a Mediterranean or sub-Mediterranean climate. The average envelope U-value is 1.88 W/m2K, and the results of this study indicate very poor thermal characteristics of the existing condition of individual elements of the envelope, expressed by U-values, which are several times higher than the allowable values.

There has been a lot of talks lately about falling interest rates in all markets. The decline in interest rates is also evident in the domestic market. Such information and trends increase caution, especially in the corporate sector, which is not conducive to economic optimism. In support of the black premonitions that have been pointed out recently, the paper also highlights the appearance of “inverse” yield curves on the Banja Luka Stock Exchange. The yield curve represents the relationship between the interest rate (or loan cost) and the time to maturity of a given borrower in a given currency. By definition, there is no single yield curve that describes financing costs for all market participants. There are conventions that everyone adheres to when it comes to choosing instruments and general design principles. The interpretation of the yield curve is very complex because the yield curve takes into account investors’ expectations in terms of interest rates, but also inflation and political cycles because it is reflected as a risk premium for long-term investments. However, the details of the design methodology are characteristic of different institutional investors. The paper describes the methodology for constructing the yield curve of the Republic of Srpska. The range and limitations of using such a yield curve are then stated are also described. The subject of this paper is to create the yield curve in a domestic market and to analyze data from such views. The aim of the paper is to scientifically explain and describe the process of creating a curve for the yield of debt securities issued by the government and to analyze and interpret the data from that curve. The research question is: “Can the yield curve on the Banja Luka Stock Exchange be used behind the presentation of the yield on debt securities over the last decade?” Thus, the paper demonstrates the scope and limitations of this model while respecting the standards and specifics of business in the emerging market. The conclusion is that the yield curve on the Banja Luka Stock Exchange is a theoretical construction rather than an empirically verified fact, in contrast to the yield curve from developed markets, but that it can be used to represent the yield on debt securities and, indirectly, as an auxiliary tool in making investment decisions. Also, the yield curve of debt securities of the Republic of Srpska is a theoretical concept, but it is also noticeable in practice. Moreover, it is a desirable tool for both academia and practitioners and the general public.

One of the important mechanical properties of packaging materials is its tensile strength. The good tensile strength is essential for materials and their mobility, packaging and for correctness when forming packing units. In this paper, stability of mechanical properties (tensile strength and elongation) was tested, for five types of plastics used as packaging material. The tested materials are made of single and combined packaging materials: PE 95 μm, OPP 20 μm, PE/OPP 20/50 μm, OPPmet 20 μm and PET/PE/OPP 12/38/30 μm. Testing of tensile strength and elongation of the material during tearing of the packaging material was performed with the following dynamics: 0, 30, 60, 120 and 180 days. The packed contents were dried apples. All materials showed good insulating properties and stability of the welding site. The quality of packaged dried apples, based on the test results, was assessed as good for the technology and product characteristics. In terms of strength PET/OPPmet/PE, OPPmet and OPP proved to be the best materials. In case of exposure of the package to mechanical loads it is recommended to use some of these three materials.

Phytochemicals represent one of the rising agents in cancer research today. They are recognized as one the most abundant bio-active compounds found in many different sources, specifically in plants.  Their anti-cancer effects have been frequently explored and reported in various research studies. However, the bioavailability and solubility of phytochemicals still represent the major issue in in vivo and in vitro research. This report analyses the effects of three different phytochemicals, commonly used for survival interference in malignant cancer clones, including thymoquinone (TQ), curcumin, and quercetin in a model of diffuse large B cell lymphoma (DLBCL). In order to characterize the impact of solubility of these compounds to their bioactivity in the DLBCL model, three different but highly widespread solvents were used. Determination of an optimal compound - solvent association is warranted when assessing the stability and activity of phytochemicals in cells. The results of this study indicate the dose-dependent decrease in cellular viability, including the treatments with all combinations of substances and solvents. In addition, we demonstrated that the choice of the solvent greatly influenced solubility and the overall effect of the compound in cancer cells. 

The article deals with the contemporary labor migrations from Bosnia and Herzegovina to Slovenia and the other countries of European Union, specifically during the period of the COVID-19 pandemic On the basis of fieldwork among the participants in these migrations, it seeks to identify the specifics of circumstances and situations that arose suddenly with the closure of political borders and the demands of social di-stancing In these circumstances, we supposed that labor migrants found themselves to be a particularly vulnerable group of population The case study has denied that this is completely true On the other hand, labor migrations from Bosnia and Herzegovina to Central, Western and North European and some non-European countries have been a continuous process for the last century and at least migration flows must be taken as a fact which directions, volumes and character are greatly influenced by labor market regulations in each individual EU member and other states Periodically, specific political and social situations also gain importance The COVID-19 pandemic has exactly such an impact © 2020, University of Ljubljana All rights reserved
