PORODIČNA AFEKTIVNA VEZANOST KOD SUICIDALNIH PACIJENATA

Rad se oslanja na Bowlby-jevu teoriju afektivnog vezivanja, u skladu sa pretpostavkom da kvalitet afektivne vezanosti u detinjstvu predviđa kasnije psihološko funkcionisanje osobe, te da samoubistvo, kao autodestruktivni čin, može biti posledica nesigurne vezanosti. Cilj ovog rada bio je utvrditi da li se pacijenti, koji su ispoljili suicidalno ponašanje, češće svrstavaju u neki od nesigurnih obrazaca vezanosti, u odnosu na zdrave ispitanike bez suicidalnih tendencija. Istraživanje je provedeno u Specijalnoj bolnici za psihijatriju u Sokocu, a uzorak je činilo 80 ispitanika muškog pola, svrstanih u dve grupe: grupu suicidalnih pacijenata (N1=40) i grupu zdravih, nesuicidalnih ispitanika (N=40). Kratkim, strukturiranim upitnikom napravljenim za potrebe ovog istraživanja, prikupljeni su podaci o subjektivnom doživljaju majke i oca. Ispitivanje porodične afektivne vezanosti provedeno je modifikovanim Brennanovim upitnikom, za procenjivanje porodične afektivne vezanosti (Stefanović-Stanojević, 2005). Za testiranje razlika između grupa korišćen je χ² test. Rezultati pokazuju da postoji statistički značajna razlika između ispitivanih grupa i to tako, da su se ispitanici iz grupe suicidalnih, značajno češće svrstavali u nesigurno-okupirani i nesigurno-plašljivi obrazac vezivanja (χ²(3)=23,928; p=0,000) i češće su odrastali uz prezaštićujuću, agresivnu ili majku sa psihičkim problemima (2(3)=28,976; p=0,000), dok razlike u odnosu na doživljaj oca nemaju statističku značajnost (2(2)=3,436; p=0,179).

PHYTOCHEMICAL STUDY TO VALIDATE THE ETHNOBOTANICAL IMPORTANCE OF Dioscorea steriscus TUBERS OBTAINED FROM ZIMBABWE

Modern people have embraced plants as a source of useful bioactive compounds. As such, plants with medicinal properties have become essential components in human life. The purpose of this study was to investigate the phytochemical profile of the extract of Dioscorea steriscus tubers obtained from Zimbabwe. Phytochemicals were extracted from tubers of D. steriscus using aqueous acetone. UV-Visible Spectrophotometry, Fourier transform infrared (FTIR) spectrometry and highperformance liquid chromatography (HPLC) techniques were used to determine the phytochemical profile of the tuber extract. The yield of phytochemicals extracted from D. steriscus tubers was found to be 6.38 %. The presence of bioactive compounds possessing phenyl, organic hydroxyl, amine, carboxyl, carbonyl, acyl, alkyl and aromatic functional groups was confirmed using UVVisible and FTIR analysis. The presence of substantial amounts of vanillic acid and kaempferol in D. steriscus tubers was confirmed using HPLC analysis. In support of the ethnobotanical values of Dioscorea species, the study confirmed the presence of potent phytochemicals in the extract of D. steriscus tubers obtained from Zimbabwe.

APPLICATION OF THE CRITERION OF TECHNOLOGICAL DAMAGEABILITY IN MECHANICAL ENGINEERING

Development and implementation in mechanical engineering practice of integrated information systems for control of technological processes of manufacturing products is the main driver of economic growth of developed countries. The priority of modern engineering technology is to provide the specified operational characteristics of products in accordance with the accuracy parameters, set by designer and quality of surface layers in contrast to achieving the minimum technological cost with maximum performance for traditional approaches. Technological providing of the main operational characteristics of the product (bearing strength, wear resistance, fatigue strength, joint strength etc.) require a systematic approach, which consists in the investigation of real physical processes at submicroscopic, microscopic and macroscopic levels of research, and step- by-step tracking required parameters at all stages of the Product Life Cycle from the position of technological inheritability. It is proposed to use the method of LM-hardness to control the quality of the structure of the material from castings in the design of functionally-oriented processes. The magnitude of the technological damage of the product material serves as a criterion for optimization when choosing a variant of surface treatment of the casting. A method for providing experimental studies of castings of aluminium alloys has been developed. On the basis of the carried-out experimental researches the rational route of processing of surfaces of casting is chosen.

SISTEM UPRAVLJANJA ZA BORBU PROTIV KORUPCIJE U PREDUZEĆU

Marketing in tourism is a systematic Korupcija je jedan od najdestruktivnijih i najkompleksijih problema današnjice, a njene poslјedice negativno utiču na poslovanje preduzeća, političku stabilnost zemlјe i standard stanovništva. Na globalnom nivou korupcija predstavlјa značajnu barijeru u međunarodnoj trgovini. Ukupni troškovi prevara teško da će se objektivno sagledati, a posebno će biti teško izračunati indirektne štete koje prouzrokuju prevare. Neke prevare neće biti nikada otkrivene. Procjenjuje se da prosječno organizacije u svijetu gube 5% godišnjih prihoda radi prevara. Mala smanjivanja troškova zbog prevara mogu značajno da povećaju profit organizacije. Vlade mnogih država donijele su nacionalne programe borbe protiv korupcije. Implementiranje antikorupcionih programa u mnogome zavisi od razvijene svijesti i etičke kulture u preduzećima. Međunarodna organizacija za standardizaciju razvila je standard ISO 37001- Sistem menadžmenta za borbu protiv korupcije. Međunarodni standard omogućava organizacijama svih vrsta sprečavanje, otkrivanje i rješavanje korupcije usvajanjem politike protiv podmićivanja, imenovanjem osobe koja će nadgledati poštivanje mjera za podmićivanje, obukom, procjenom rizika i dubinskom analizom projekata i poslovnih saradnika, provođenjem financijskih i komercijalne kontrole, te uspostavljanje postupaka izvještavanja i istrage. Pružajući globalno priznat način za rješavanje destruktivnih kriminalnih radnji koje pretvaraju bilijon dolara prljavog novca svake godine, ISO 37001 direktno se bavi jednim od najrazornijih i najizazovnijih svjetskih problema i pokazuje predan pristup suzbijanju korupcije. U radu je predstavlјeno istraživanje nivo korupcije u Bosni i Hercegovini, koje je poređeno sa nivom korupcije u drugim zemlјama, kao i korelacija sa globalnim indeksom konurentnosti. Na kraju rada predstavlјena je metodologija za projektovanje i uvođenje sistema menadžmenta za borbu protiv korupcije u preduzeću. Rezultati istraživanja donose nove naučne činjenice i saznanja u borbi protiv korupcije i metodološki postupak za implementiranje sistema menadžmenta za borbu protiv korupcije u preduzeću.

PESTICIDES; A NECESSARY EVIL IN THE AGRICULTURAL VALUE CHAIN- A REVIEW

Even though pesticides constitute a very essential component of improved and modern agriculture, the abuse of pesticides has brought substantial poisoning worldwide, especially in developing countries. This review investigates the possible sources by which people are exposed to pesticides worldwide and the impact on their livelihood. The group who often are exposed to these chemicals includes, farm workers, children, farmers, and family members who have direct link to the pesticide application sites as well as persons who are exposed to these pesticides through the domestic use of waterbodies and consumption of foodstuff or crops sprayed with these pesticides. Central to this review is the critical discussions of the different scientific research findings on health effects and risks related to pesticides usage. Again, organophosphates and organochlorines pesticides are found in most of the pesticide contaminated sites and can remain in soil and waterbodies for a longtime. This work has also provided cases of incidence of carcinogenicity in humans, as a result of pesticides use. We concluded that, breeding or developing insect tolerant or resistant crops may curb the profuse use of pesticides in agriculture.

УТИЦАЈ УНАПРЕЂЕЊА ПРОДАЈЕ НА ПОНАШАЊЕ ПОТРОШАЧА

Тржиште малопродаје у Републици Српској једно је од најбрже растућих тржишта у последњих двадесетак година. То није случај само у Републици Српској и окружењу, већ и широм свијета. Доказ за то представља раст ланаца маркета, мегамаркета, тржних центара и других специјализованих малопродајних објеката. Много је лакше остварити раст на тржишту, а тиме и пословни успјех, него задржати конкурентност на изузетно пробирљивом и релативно доброснабдјевеном тржишту, какво је малопродајно тржиште Републике Српске. Један од начина задржавања конкурентности и истовременог раста је унапређење продаје којим продавци разним инструментима стимулишу потрошаче како би куповали производе из широког асортимана властите понуде.Циљ овог истраживања је управо да се утврди како и на који начин унапређење продаје утиче на понашање потрошача у куповини. Цјелокупно истраживање заснива се на потврђивању постављених хипотеза, а добијени резултати се могу користити у даљем истраживању и доказивању како инструменти унапређења продаје утичу на понашање потрошача.

INTERCONNECTION OF MATERIALS SCIENCE, 3D PRINTING AND MATHEMATIC IN INTERDISCIPLINARY EDUCATION

The substantial advantage of 3D printing is the ability to fabricate complex shapes objects from liquid molecules or powder grains which joins or solidifies using computer design files (CAD) to produce a three-dimensional object with material being added together layer by layer. This process is considered as an industrial technology. The most-commonly used 3D printing procedure is a material extrusion technique called fused deposition modelling. The producers of 3D printers have already developed prototypes for education purposes. The importance of the incorporation this printing method in schools is the fact. The learning experience for digital media is becoming a priority in school education. The practical application of this technique can be incorporated into a wide variety of school subjects to simplify the sophisticated theoretical concepts. 3D printing is the example of cooperation within material science and mathematics but this platform is very often not supported by the high school curriculum, but latest trends propose different approaches and make education close to the science achievements and contemporary life. Building lessons plans and project could help students to learn more contemporary achievement in this field. It is new trend to support enthusiastic teachers who want to implement this method of additive manufacturing in education. This paper provides an overview of 3D printing methods and highlights the possibility of their implementation in educational techniques.
