Effect of Different Covering Treatments on Chemical Composition of Early Potato Tubers
No full textPotatoes hold a signifcant position as one of the most important crops. Their value
lies not only in their nutritional composition but also in their function as raw materials for various processing purposes. Furthermore, the cultivation of early potatoes
carries considerable agrotechnical importance due to their ability to serve as the
initial crop in intensive crop rotation, optimizing the utilization of agricultural soil.
The primary objective of its production is to reach a consistent and high yield of
premium quality. Additionally, the aim is to enter the market as early as possible and
maximize proftability. To achieve these goals, producers utilize specifc covering
treatments such as mulching and plant covering to ensure earlier and safer production, thus maximizing profts. Our research aimed to determine the impact of diferent covering treatments (biodegradable mulch, agrotextile, low tunnel) on the chemical composition of early potato tubers. A 3-year feld experiment was managed in
Begeč (Serbia) with two early potato cultivars, Cleopatra and Riviera. The tested
covering treatments signifcantly infuenced the quality of early potatoes, by increasing the content of dry matter, starch, vitamin C, cellulose, and ash in the tubers and
by reducting sugar and nitrate content
Uticaj klimatskih promena na potencijal ljudskih resursa sa aspekta održive gradnje
No full textSrbija se nalazi u procesu usklađivanja i inkorporacije evropskih propisa o građevinskim proizvodima u domaće zakonodavstvo, odnosno propise. Održivi razvoj kao koncept svoje osnovno usmerenje vezuje za očuvanje prirodnih ekosistema i racionalno korišćenje prirodnih bogatstava zemlje, kao i na načine i upravljanje vezano za podizanje kvaliteta životne sredine i života u bezbednom i zdravom okruženju. Neophodno je ostvariti rezultate vezane za definisanje globalnih razvojnih ciljeva, smanjenje rizika od štetnih efekata klimatskih promena i planova vezanih za strategiju kako bi se pronašli načini da zelena ekonomija postane jedan od glavnih katalizatora privrednog rasta, zapošljavanja i smanjivanja siromaštva u regionu. Održiva gradnja ne podrazumeva samo resurse poput zemljišta, materijala za gradnju, transporta i drugo. Ono što je najbitniji resurs u doba ekonomije znanja su ljudski resursi i njihov potencijal. Ljudski resursi su važan segment održivosti, ekonomije znanja, ekonomske isplativosti u odnosu na profitabilnost, rentabilnost, iskorišćenost, kao i na oblast održive gradnje. Veoma važna pretpostavka održivosti gradnje su materijali koji se koriste, a koji obezbeđuju energetsku efikasnost zgrada. Ovaj rad obuhvata više naučnih oblasti kao što je zelena i (bio)ekonomija, cirkularna ekonomija, održivi razvoj, zaštita životne sredine i bezbednost. Cilj rada je da se ukaže na uticaj klimatskih promena
na potencijal ljudskih resursa u oblasti održive gradnje i projektovanja pametnih eko zgrada u Srbiji sa osvrtom na praksu Evropske unije.Serbia is in the process of harmonizing and incorporating European regulations on construction products into domestic legislation, i.e. regulations. Sustainable development as a concept has its basic focus on the preservation of natural ecosystems and the rational use of the country’s natural resources, as well as on methods and management related to raising the quality of the environment and life in a safe and healthy environment. It is necessary to achieve results related to defining global development goals, reducing the risk of adverse effects of climate change and strategic plans in order to find ways to make the green economy one of the main catalysts of economic growth, employment and poverty reduction in the region. Sustainable construction does not only include resources such as land, building materials, transportation and more. The most important resource in the era of the knowledge economy is human resources and their potential. Human resources are an important segment of sustainability, knowledge economy, economic profitability in relation to profitability, profitability, utilization, as well as the field of sustainable construction. A very important assumption for the sustainability of construction is the materials used, which ensure the energy efficiency of buildings. This work covers several scientific areas such as green and (bio)economy, circular economy, sustainable development, environmental protection and security. The aim of the work is to indicate the impact of climate change on the potential of human resources in the field of sustainable construction and design of smart eco-buildings in Serbia with reference to the practice of the European Union.Urednici: prof. dr Andrea Andrejević Panić, prof. dr Jelena Ješić i prof. dr Simonida Vukadinović; tehnički urednici: prof. dr Simonida Vukadinović, prof. dr Jelena Ješić, prof. dr Andrea Andrejević Panić i doc. dr Zoran Brlja
Effects of Specific RAMP Protocol Phase on Change of Direction Speed of Police Students
No full textBackground: This study assessed the effects of two distinct RAMP (Raise, Activate, Mobilize, Potentiate) protocols, mobility-focused and reactiveness-focused, on change of direction speed in police students (i.e., tactical athletes). Methods: A longitudinal design with two experimental and one control group was employed. The study sample consisted of 39 police students (aged 19.2 ± 0.2 yrs) who were randomly allocated into three equal groups of 13 participants (7 females and 6 males). Experimental groups were labeled as the mobility group or reactiveness group based on the type of RAMP protocol they performed. During the tactical physical education classes, the mobility group performed four complex mobility exercises, while the reactiveness group performed four exercises for trunk reactiveness. After the specific warm-up, both groups continued with syllabus activities. The control group performed only regular activities based on the study syllabus. All participants performed the Illinois Agility test unloaded (IAT) and loaded (10 kg vest [IATL]) and Functional Movement Screening (FMS) before and after 8 weeks of the applied protocols. Results: In general, improvements were observed across all participants in the IAT (p < 0.001), IATL (p < 0.001), and FMS (p < 0.001). The mobility protocol had a more substantial impact compared to the reactiveness protocolontheIAT(d=0.55vs. d=0.40),IATL(d=0.44vs. d=0.38),andFMS(d=0.88vs. d = −0.42). Additionally, the control group, which did not follow either RAMP protocol, did not show significant improvements. Conclusions: These results underscore the importance of incorporating targeted mobility training in the limited time available for strength and conditioning programs, as it improves occupationally relevant movement qualities such as change of direction speed ability. Prioritizing mobility training in young tactical athletes may offer broader benefits compared to reactiveness training

Possibilities of application of modern educational technology in teaching art subjects.
No full texthe paper discusses the possibilities of application of modern educational technology in teaching art subjects, specifically music and art culture, in primary school. Modern educational technology, including digital platforms, multimedia tools and interactive applications, offer significant potential for enriching the teaching process, making it more dynamic, interactive and adapted to the needs of students. Using these resources, teachers can combine traditional teaching methods with modern technologies, which allows students to learn in a way that is more adapted to their interests and needs, with a richer visual and audio experience. In this regard, the aim of this paper is to explore the advantages and challenges of integrating these technologies into teaching art subjects. Special attention is paid to the impact of technology on student creativity, motivation and engagement, as well as the role of teachers in integrating these resources into teaching. The paper emphasizes the importance of developing teachers’ digital competencies, which are key to the successful implementation of modern teaching of art subjects. The role of the teacher in such teaching is multifaceted and requires responsibility, patience and flexibility. The teacher acts as a guide and mentor who helps students safely explore and use all the opportunities that technology offers them, while at the same time encouraging them to creative expression and independent learning. With proper guidance and support, the teacher helps students develop not only artistic, but also digital skills that will be valuable to them in the future. The paper presents examples of good practices and recommendations for improving teaching through the innovative use of modern educational technology

From gender equality to gender neutrality, a need or a trend? Experiences from Sweden
No full textРодна неутралност као концепт потиче из постконструктивистичког феминизма потенцирајући једнакост без претпоставки и захтева у виду родних улога. Циљ рада је да прикаже значајне показатеље родне неутралности у Шведској, која заузима водеће место по показатељима за родно неутрално друштво и положај Србије која је у вишегодишњем процесу реализације политике родне равноправно сти. Чињеница је да се напредак у наведеним кључним областима унапређивања родне равноправности у Србији дешава изузетно споро што говори и податак да би тек за 59 година могли да очекујемо високо остварење анализираних параметара кроз пуну равноправност. Упоређујући Србију са земљама у ЕУ по Индексу родне равноправно сти 2018, запажа се да заостајемо за 9,4 поена у просеку, док за Шведском бележимо заостатак од 25,8 поена. У раду постављамо важна питања којима треба да се бави на учна и стручна јавност а тичу се критичког сагледавања родно неутралне образовне будућности Србије и колико смо ми као друштво спремни за исту.Gender neutrality as a concept stems from post-constructivist feminism, emphasizing equality without assumptions and requirements in terms of of gender roles. In its essence, it emphases justice and equal treatment for all. Unlike traditional views of gender and sex, gender neutrality underlines self-awareness and investigation as to how gender can affect behaviors and relationships. The aim of this paper is to present important indicators of gender neutrality in Sweden, which holds a leading position according to the indicators for gender neutral society, and the position of Serbia, which has been undergoing a longstanding process of implementation of the gender equality policy. The fact of the matter is that progress in these key areas of gender equality improvement in Serbia is happening extremely slowly, which is supported by the fact that only in 59 years could we expect the analyzed parameters to be wholly met through full gender equality. Comparing Serbia with the EU countries according to the Gender Equality Index for 2018, it can be noted that we are 9.4 points behind on average, while we lag behind Sweden by 25.8 points. In this paper we ask important questions that should be addressed by the scientific and professional community, concerning a critical review of the gender-neutral educational future of Serbia, and how we, as a society, are ready for it
