Authors: Božinovski Adrijan , Tanev George , Stojčevska Biljana , Pačovski Veno , Ackovska Nevena
Published: November 2017

This paper presents the space complexity analysis of the Binary Tree Roll algorithm. The space complexity is analyzed theoretically and the results are then confirmed empirically. The theoretical analysis consists of determining the amount of memory occupied during the execution of the algorithm and deriving functions of it, in terms of the number of nodes of the tree n, for the worst - and best-case scenarios. The empirical analysis of the space complexity consists of measuring the maximum and minimum amounts of memory occupied during the execution of the algorithm, for all binary tree topologies with the given number of nodes. The space complexity is shown, both theoretically and empirically, to be logarithmic in the best case and linear in the worst case, whereas its average case is shown to be dominantly logarithmic.

Under industrial conditions of slaughtering of pigs, cattle and poultry inedible by-products are obtained besides meat. A lot of these by-products represent a possible source for production of feed ingredients of animal origin and technical fat. For better utilization of animal materials and production of qualitative products it is necessary to recognize well characteristics of these materials.This study shows results of investigations of basic chemical composition, nitrogen fractions and amino acid composition, of some inedible by products from slaughtering of animals, with aims of indication of their high potentials.Obtained results indicate that the examinated inedible by-products of slaughtered pigs (blood, intestines without their contents, mixed meat-fatty wastes and confiscates (lungs)) represent potent source of nutritive materials for production of valuable feeds. Mixed meat-fatty wastes are characterized by their high fat content (38%), and blood can be seen as significant source of essential amino acids. Chemical composition of examined bovine bones show that fresh bones are a good medium for processing into a raw material for the production of gelatin and bone marrow for chemical industry.

Published: November 2017

The aim of this study was to estimate the influence of diet supplemented with linseed rich additive under commercial name Vitalan on omega-fatty acids content in piglet meat. The main ingredient in Vitalan is extruded linseed, that contribute the diet is rich in omega-3 fatty acids. Piglets were divided in control and experimental group and reared to 33 kg of average live weight. Experimental group was fed the standard diet enriched with 2.5% of Vitalan. After the end of fattening period, the meat samples from both groups were analyzed for omega-3 and omega-6 fatty acids content in raw and oven- roasted meat. The ratio between omega-6 and omega-3 acids was established. Additionally, other parameters, such as weight gain, health and behaviour of piglets were observing during the study. The treatment with linseed enriched diet resulted in higher omega-3 acids content, which lowered ratio between omega-6 and omega-3 acids in meat, thus making it better for a human nutrition from a health perspective.

Published: November 2017

One of the big new areas of development of the advanced composite materials is in combining natural fibers with thermoplastics for producing lightweight, environmentally friendly, cost-effective composite material.The aim of this work is to show the possibilities of recycling and reuse of thermoplastic polymer matrices with rice hulls (RH) and kenaf fibres (KF) using the conventional techniques, extrusion and compression moulding. The matrices (polypropylene (PP) and poly(lactic) acid (PLA) ) were recycled one and two times and the fibers/filler were compounded with recycled matrix. The processing and material properties have been studied on the composites with recycled matrix and compared to the composites with virgin matrix.Characterization of all composites includes mechanical, morphological and thermo-gravimetrical analysis. Тhe flexural properties for PP recycled based composites were held close to the flexural properties for composite based on neat PP, but for PLA recycled based composite the flexural properties are decreased for about 50%. The thermal stability of recycled matrices based composites is very similar to the thermal stability of the composites with virgin matrix. SEM analysis has shown that the fillers/fibers are covered by the recycled polymer matrix, indicated on the satisfied durability of the recycled polymer matrices. The obtained results have shown that both polymer matrices (biodegradable and no degradable) could be recycled with acceptable mechanical properties and they can be successfully used for production of eco-composites.

Authors: Srebrenkoska Vineta , Bogoeva Gaceva Gordana
Published: November 2017

Biodegradable poly (lactic acid) (PLA) based biocomposites reinforced with rice hulls were prepared by compression molding and their properties were compared to those of commonly used thermoplastic based-polymer, polypropylene (PP) containing the same reinforcements.Rice hulls from rice processing plants represent renewable sources that could be utilized for production of new class of eco-materials. In this study, rice-hulls-filled poly (lactic acid) (PLA) biocomposites were prepared through addition of 5 wt. % PLA-grafted-MA (CA) for enhancement of adhesion between polymer matrix and natural filler. The composites containing 30% wt. rice hulls (RH) were prepared and the possibility of recycling and reuse of these biocomposites were investigated. For all biocomposites, the mechanical and thermal properties were analyzed and compared to those of commonly used thermoplastic based-polymer, polypropylene (PP) containing the same reinforcement. Thermal stability of neat biocomposites and of the new composites produced from recycled ones was practically unchanged. Utilization of the mixture obtained after the thermal-mechanical recycling of the whole biocomposite has resulted into composite with slightly increased flexural modulus and decreased flexural strength.The obtained results have shown that rice-hull-filled poly(lactic acid) biocomposites could be recycled and utilized for production of new eco-materials with acceptable thermal and mechanical properties. Namely, the results for flexural strength and modulus of the recycled biocomposite samples are comparable to those of conventional formaldehyde wood medium density fiberboards used as construction elements for indoor applications.

Authors: Vujadinović Dragan , Marjanović-Balaban Željka
Published: November 2017

The real importance of meat in human nutrition has been defined during the last century. Professional and scientific publications of the twentieth century are often written about the nutritional value of meat. Thermal processing of meat is as old as civilization itself. Meat drying as a procedure for a longer shelf life, probably first appeared as a result of some accident in which the fresh meat has been exposed to heat. The first works about the problems of heat treatment of pork were published in the 1950s.The aim of this paper was to investigate the effect of temperature and different methods of heat treatment on chemical properties of processed pork meat. To determine the optimal conditions for various heat treatment processes, in this paper, meat processing was performed at different temperatures, and set the temperature range from 51 ºC to 100 ºC. Therefore, the meat is processed by dry heat treatment (roasting) and cooking in water (at atmospheric pressure). Then, the change of chemical composition of processed meat was noted (moisture content, ash, fat, protein, micronutrients).

Published: November 2017

Although there is considerable interest in glucose oxidase, little is known about its activity on rheological characteristics of wheat dough and with bread making quality. Influence that the glucose oxidase exerts on rheological properties of the wheat dough is investigated on the basic of rheological determinations obtained with alveograph. Influence of glucose oxidase on bread making properties is determined on the basic of result obtained from the laboratory scale baking tests. In order to clearly establish relations between added dose of glucose oxidase (0.002; 0.004; 0.006 %) and rheological properties of wheat dough, as well as with bread making quality, analysis of dough with and without glucose oxidase (control sample) is performed and results are discussed with comparison with L-ascorbic acid as the most commonly used oxidative improver. Results show that glucose oxidase cause greatest increase of dough tenacity and causal reduction of extensibility. This leads to a negative effect on specific volume. Glucose oxidase cause increase of crumb hardness in smaller extent than L-ascorbic acid.

The aim of this study was to evaluate the effects of replacing of sodium nitrite curing salt with the mixture of sodium and potassium chloride (Na-max 27 g/kg-min K 16 g/kg) at a rate of 25%, 50%, 75% and 100% on the quality, microbiological stability and colour of the cooked sausages - hot dog. Five production batches (PB) were manufactured. The first C (control) was prepared according to the manufacturer’s original recipe. Experimental PB I was made by adding 50 g of mixed sodium-potassium salt (25%) and 150 g nitrite curing salt into 10 kg of stuffing, in PB II was replaced 50%, in PB III 75% nitrite salt. Hot-dogs of PB IV were made by adding 200 g (100%) of combined sodium-potassium salt into 10 kg of mass.The results obtained clearly indicate a continuous decrease of sodium content in samples originating from the control group to the experimental samples PB IV, in which the nitrite salt was fully replaced with a mixture of potassium-sodium salt. Replacing of sodium nitrite salt with the mixture of sodium and potassium chloride did not significantly affect examined chemical parameters (content of moisture, proteins, fat, ash) of experimentally prepared hot-dogs. Replacing of sodium nitrite salt with the mixture of sodium and potassium chloride did not significantly affect examined colour (CIE L*, a*, b*) of experimentally prepared hot-dogs.
Mathematical Approach to Strokes as an Attractor Within Communication Dynamical System
Authors: Andonović Beti
Published: November 2017

Transactional Analysis as a personality theory has offered some powerful concepts to explain and improve communication between individuals. On the other hand, positive productive communication among large numbers of people, as a compound set of transactions, as an essential aspect of human survival has not been so well explained. Like the weather and other chaotic processes, group behavior is not easily understood or predicted. It has been long suspected that in large groups of people (organizations, communities, societies), positive communication has a leading role in maintaining the duration and quality of communication. It is the aim of this paper to relate the mathematics notion of dynamical systems to the compound system of communication. The postulate that strokes, a concept introduced by E. Berne as a way in which people recognize each other, and elaborated by Steiner as a way of exchanging information, is discussed as a concept that introduces stability into the functioning of large groups.

Authors: Ivanović Sandra
Published: November 2017

Music, from its beginning to present time, most directly influences the spiritual development of man. From its beginning, through ancient civilizations to the present time, music has had an immeasurably important role in the formation of personality and, according to recent studies, a very important role in the influence on human health. Music therapy, as a separate branch of medicine, deals with the beneficial effect of music on the disorders in personality development, the treatment of various psychiatric disorders, as well as other kinds of diseases. This paper will show the effects, particularly in Bosnia and Herzegovina and the region, because of the social events of the past few decades, of various musical trends which affect negatively the development of the spiritual side of the personality, and have long-term consequences on the understanding and building up the value system. Additional exposure to media propagation of such music trends, and the negative effects that it entails, requires restoring the true values of art music.

Published: November 2017

The disposal of coal fly ash obtained in thermal power plants presents the general problem all over the world. Significant research on the utilization of fly ash has been carried out in the area of construction materials. The aim of this study was to develop porous ceramics based on coal fly ash and clay (60wt.%clay and 40wt.% fly ash). Three types of pore creators: two types of wood cutting (Quercus and Facus sylvatica) and C-powder were used for creating of the porous ceramics. The mixtures based on fly ash and clay and different content of pore creators (2, 5, 10 and 20wt.%) were consolidated (P=45 MPa, T = 900, 1000, 1050 and 1100oC/1h) to obtain porous ceramic (PC). The results indicate that the properties of the porous ceramics depend on the type and content of the pore creators. Furthermore, the sintering temperature was found to be main factor affecting the properties of the sintered products. The maximal bending strength (26 MPa) was achieved by using 2wt% P3 (C-powder) and the porous ceramics has the density and porosity of 1.90g/cm3 and 22%, respectively. By using the highest content (20wt.% ) of each pore creator (P1, P2 and P3) the lowest bending strength cca 5 MPa was achieved and the variation of the density and porosity was in the range from 1.22 to 1.32 g/cm3 and 44 to 48%, respectively. Water absorption, durability and the microstructure of the obtained porous ceramics are also reported in this paper.

A chronic wound can greatly impair the quality of life of patients. Early we can consider chronic if there is no complete healing after six weeks of treatment. Over time, several different instruments have been developed to monitor the impact of a chronic wound on the quality of life of patients. The original required a lot of time to complete, remained incomplete, and there was a need to develop a standardized, short, multi-dimensional questionnaire. This led to the formation of a “Wound-QoL” questionnaire used in assessing the quality of life of patients with a chronic wound.In our institution, a pilot study was conducted on the impact of chronic wounds on the quality of life of patients, using a validated questionnaire. The study included 32 patients whose wounds were transplanted to the Institute. The questionnaires were completed at the beginning of the wound treatment at the institution.In physical terms, a chronic wound has a central impact on our respondents, but its psychological impact is most pronounced. On everyday activities, the influence of the wound is assessed in men as small, and an equal number of women consider it to have a small and big effect. Respondents believe that treating chronic wounds does not carry a large financial burden. It is necessary to assess the quality of life of patients with chronic wound before and after treatment and possible healing of the wound in order to see the impact of chronic wounds on the positive psychological state of the wound and the motivation to heal.

Drastično smanjenje kretanja i telesne aktivnosti direktno se odražava i na zdravstveni status mladih. Studentska populacija, takođe, nije izuzeta iz ovakvih trendova.Optimalne fizičke aktivnosti su uslov za očuvanje zdravlja i normalnog funkcionisanja organa budući da kretanje predstavlja imanentnu potrebu čoveka koja je, od strane psihologa, svrstanu u sferu primarnih bioloških motiva. Zbog toga je i predmet ovog istraživanja bio usmeren na procenu stanja indeksa telesne mase (BMI) kod populacije studenata Panevropskog univerziteta Apeiron u Banjoj Luci. Cilj rada je, između ostalog, bio i utvrđivanje specifičnosti distribucionih parametara, te njihov eventualni uticaj na opredeljenja prema sportsko-rekreativnim aktivnostima na Univerzitetu.Istraživanje je realizovano na Panevropskom Univerzitetu Apeiron u Banjoj Luci, kao transverzalna studija, uz primenu Survay metoda i obuhvatilo je ukupno 321 ispitanika, studenata ovog Univerziteta. Istraživački cilj je bio usmeren, između ostalog, i na detekciju indeksa telesne mase studenata i njegov eventualni uticaj na opredeljenja prema upražnjavanju sportsko-rekreativnih aktivnosti u okviru Univerziteta.

Istraživanje je provedeno na uzorku od 137 fudbalera uzrasta 14 do 16 godina iz fudbalskih klubova Srednjobosanskog kantona, sa kojim je proveden posebno programirani trenažni postupak u trajanju od šest mjeseci sa 72 trenažne jedinice.Osnovni cilj istraživanja bio je da se utvrdi stepen povezanosti (relacije) morfoloških odlika i bazičnih motoričkih sposobnosti sa rezultatima u situaciono-motoričkim testovima u dva trenažna stanja.Za utvrđivanje stepena povezanosti (relacija) između morfoloških odlika, bazičnih motoričkih sposobnosti i situaciono-motoričkih sposobnosti primijenjena je klasična kanonička korelaciona analiza (inicijalni i finalno stanje). Dobijeni rezultati istraživanja su pokazali da je program fudbala koji je u suštini bio usmjeren na direktno „programiranje“ obrazaca optimalnih kretanja u fudbalu proizveo integraciju i homogenizaciju istraživanih prostora u kojem su specifične strukture fudbalskih kretanja integrisana i povezana sa bazičnim motoričkim sposobnostima i morfološkim odlikama.

U skladu sa pravcima razvoja banjalučke regije, turizam se naglašava kao jedna od prioritetnih privrednih djelatnosti. Problem istraživanja je utvrditi odnos posjetilaca turističkih destinacija banjalučke regije prema sportsko–rekreativnom vježbanju uopšte i sportsko–rekreativnom vježbanju kao dijelu turističke ponude, te utvrđivanje veza demografskih karakteristika posjetilaca i njihovog odnosa. Generalno posmatrajući, cilj ovog rada je iznalaženje faktora i mogućnosti unapređenja sportsko-rekreativnih sadržaja i objekata u turističkoj ponudi na području banjalučke regije, kao dijela turističke ponude. Dobijeni rezultati ukazuju na pozitivan odnos ispitanika prema sportsko-rekreativnim sadržajima kao dijelu turističke ponude i na potrebu poboljšanja istih. Statistički se značajno razlikuju odnos ispitanika različite stručne spreme gdje pozitivan odnos iskazuju ispitanici sa višom stručnom spremom. Uočeno je da postoji potreba za povećanim učešćem kvalitetnih sportsko-rekreativnih programa koji će svoje mjesto naći u turističkoj ponudi banjalučke regije.

Istraživanje je sprovedeno na uzorku od 24 najbolja takmičara Džudo kluba „Kinezis“, uzrasta od 15 do 18 godina, telesna težina 66kg ±15,50. Svi ispitanici podvrgnuti su identičnom protokolu istraživanja. Ispitanici su bili podeljeni u dve uzrasne kategorije (kadeti 12, juniori 12). Cilj istraživanja bio je utvrditi razliku u anaerobnom kapacitetu između pomenutih grupa. Za procenu anaerobne sposobnosti džudista primenjen je specijalni džudo fitnes test. Primenom t-testa nisu utvrđene razlike između kadeta i juniora što se može pripisati identičnom trenažnom programu i sličnom sportskom stažu testiranih džudista.

Otkrivanje povezanosti situacijske učinkovitosti u košarci s drugim varijablama moglo bi doprinijeti boljem razumijevanju ukupne situacijske učinkovitosti košarkaša. Cilj našeg istraživanja bio je utvrditi povezanost varijabli vezanih uz košarku (zapisničkih i demografskih) s različitim parametrima situacijske učinkovitosti vrhunskih hrvatskih seniorskih košarkaša. Finalni uzorak ispitanika (74 košarkaša) je selekcioniran iz inicijalnog uzorka košarkaša iz devet muških seniorskih košarkaških momčadi A-1 Hrvatske lige. Za analizu odnosa varijabli dva skupa podataka (parametara situacijske učinkovitosti te zapisničkih varijabli), kao i unutar istog skupa podataka (zapisničke varijable) korišten je Pearsonov koeficijent korelacije. Na osnovu dobivenih rezultata može se konstatovati da su zapisničke i demografske varijable pokazale velik broj statistički značajnih povezanosti sa standardnim i izvedenim parametrima situacijske učinkovitosti košarkaša. Uspješnost šuta za dva poena je važan kriterij kojim se treneri rukovode pri odabiru momčadi, dok košarkaši uspješniji u šutu za tri poena igraju kratkotrajnije.

Istraživanje je sprovedeno na uzorku od 204 ispitanika - učenika oba pola osnovne škole „Vuk Stefanović Karadžić“ iz Banje Luke. Od ukupnog broja ispitanika mušku populaciju činilo je 119 ispitanika, a žensku populaciju činilo je 94 ispitanika. Svi ispitanici redovno pohađaju nastavu fizičkog vaspitanja. Za procjenu posturalnog statusa primijenjene su varijable za procjenu deformiteta kičmenog stuba u sagitalnoj i frontalnoj ravni (kifoza, lordoza i skolioza).Ove varijable su primijenjene iz razloga što pokrivaju najviše prisutne deformitete na lokomotornom aparatu kod populacije uzrasta odabranih ispitanika.Osnovni cilj istraživanja bio je da se utvrdi stvarno stanje prisustva i učestalosti deformiteta na kičmenom stubu kod učenika oba pola od VI do IX razreda osnovne škole „Vuk Stefanović Karadžić“ iz Banje Luke.Rezultati istraživanja ukazuju da je kod većeg broja ispitanika obuhvaćenih ovim istraživanjem utvrđeno loše držanje tijela i izražen jedan ili više deformiteta kičmenog stuba.

Cilj ovog rada je da da se ustanovi koji sportovi su najpopularniji kod učenika osnovnih škola na teritoriji Beograda, kako bi se ustanovilo koje bi sportove bilo poželjno uvesti kao izborni čas u nastavi fizičkog vaspitanja. Uzorkom je bilo obuhvaćeno 3 090 učenika. Najpopularniji sportovi su bili košarka, plivanje, odbojka a najmanje popularni akrobatika, orijentiring, ritmička gimnastika. Pokazalo se da postoji statistički značajna razlika u odnosu na pol (dječaci su u većoj mjeri priželjkivali uvođenje košarke i fudbala a djevojčice odbojke i plivanja), opšti uspjeh (đaci sa odličnim uspjehom su najčešće predlagali plivanje i odbojku, a učenici koji su imali vrlo dobar, dobar i dovoljan uspjeh su preferirali košarku) i bavljenje sportom (učenici koji se aktivno bave sportom kao i oni koji se više ne bave su preferirali košarku i plivanje a oni učenici koji se nikada nisu bavili sportom su preferirali odbojku i košarku).
Rekreativni turizam, organizacija zimovanja i letovanja sa aspekta nastave aktivnosti u prirodi

Published: November 2017

U osnovi rad teorijski tretira problematiku organizacije i realizacije određenih vannasatvanih školskih aktivnosti sa aspekta nastave Aktivnosti u prirodi u školama. U školskim planovima i programima, navodi se da škole mogu organizovati zimovanja i letovanja ukoliko za to imaju uslova. U praksi se vrlo često susrećemo sa nepravilnim postupcima oko organizacija određenih modela aktivnosti u prirodi, pa je namera autora zasnovana na činjenici da na jedan posredan način predoče osnove turizma sa organizacijom i realizacijom zimovanja i letovanja, kako bi u praksi bilo što manje problema i propusta. Ova vrlo primamljiva i zahtevna tema nije do sada na ovaj način obrađivana i sagledavana, pa stoga autori smatraju da će u tome dati samo jedan manji doprinos.
