<p>TIMMS istraživanja su izvr&scaron;ena sa ciljem unapređenja obrazovnog sistema na svjetskom nivou. Istraživanja su bazirana za oblasti iz matematike i prirodnih nauka. Pored toga, izvr&scaron;ena su testiranja nekoliko faktora koji imaju uticaj na razvoj učeničkih postignuća na polju informatičke pismenosti. Istraživanjem je dokazano da mentori ili nastavnici treba da budu dovoljno spretni kako bi uspostavili komunikaciju sa NET generacijom mladih. Upotrebom računara ili tableta za vrijeme nastave omogućava se uspostavljanje veze sa mladim rođenim u digitalnoj eri, prilagođavanjem nastavnih sredstava podiže se nivo interakcije. Istraživanjem je dokazano da posjedovanjem naučne laboratorije i upotrebom računarskih tehnologija značajno se utiče na razvoj informatičke i naučne pismenosti.&nbsp;<br />Posjedovanjem vlastitog mobitela i računara ima značajan uticaj kada su u pitanju usvajanja znanja iz prirodnih nauka i matematike. Prema tome, uvođenjem digitalnih tehnologija i inovacija u obrazovni sistem, trend slabih rezultata na međunarodnim istraživanjima bi trebao biti pro&scaron;lost.</p>

<p>Funkcioniranje triju službenih jezika u Bosni i Hercegovini predstavlja vrlo interesantan model pripremanja tekstova na bosanski, hrvatski i srpski jezik, te se dokumenti važni za pravni sistem na&scaron;e države objavljuju tako da svaki ima svoje tri vrlo slične <span style="text-decoration: underline;">verzije.</span> U ovom radu analiziratće se dokument s nazivom Preporuke o priznavanju specifičnih oblika učenja na bosanskome i srpskome ili Preporuke o priznavanju specifičnih vidova učenja na hrvatskome, a cilj rada jeste da se izdvoje uočene razlike među verzijama, sagleda odnos različite i jednake upotrebe određenih jezičkih pojava, te rasvijetli gramatička opravdanost prikazanih razlika. Time bi se dodatno sagledao cjelokupan proces nastanka triju verzija&nbsp; jednoga dokumenta, njihovo normativno upori&scaron;te i vrijednost te, konačno, ukaže na put i<br />stranputice kojim već 20-ak godina hode službeni jezici u BiH.</p>

The aim of the research was to determine the total content of cadmium (Cd) and copper (Cu) in agricultural soils and to determine the potential toxicity of different intake routes for children and adults. Two locations were selected (Tomislavgrad and Mostar) where field crops were grown. Taking soil samples and determining the content of Cd and Cu was carried out according to the Instructions on determining the permitted amounts of harmful and dangerous substances in the soil and their testing methods (Official Gazette of FBiH, no. 96/22). A health risk assessment model based on the guidelines of the US Environmental Protection Agency (USEPA, 1996; USEPA, 2002; USEPA, 2011) was used to calculate the human health risk assessment. The measured values of the total content of copper and cadmium at the Tomislavgrad location are in accordance with the prescribed limit values. The copper content at the Mostar location was 205.90 mg/kg, which is above the limit value, and the cadmium content is in accordance with the prescribed limit values. When the HI value is less than 1, then there is no risk to human health, but if the values are greater than 1, then there is concern about non-carcinogenic risks (USEPA, 2004). The USEPA considers a carcinogenic risk in the range of 1×10–6 to 1×10−4 to be acceptable to human health. Calculations for non-carcinogenic and cancerous health risks were following the limit values.

<p style="text-align: justify;">This paper deals with the numerical determination of the stress intensity factor KI for meridional cracks on the ellipsoidal head of pressure vessels. The experiment was carried out according to selected parameters, including vessel diameter, wall thickness and pressure. The analysis of the results concluded that the cylindrical segment of the ellipsoidal head and the crown of the ellipsoidal head are the most critical places for the appearance of cracks, exposed to tensile stresses. Regression analysis determined that the internal pressure has the greatest influence on the KI factor, while the diameter of the vessel is also significant for the crown of the ellipsoidal head. The conducted experiments confirm the obtained regression models, although deviations attributed to the imperfections of the numerical simulations were observed. Despite this, it is concluded that the obtained values of the KI factor are satisfactorily accurate.</p>

<p style="text-align: justify;">Fracture mechanics is a field that is increasingly studied and applied in modern industry. One of the most widely accepted methods for assessing structural integrity in this field is the SINTAP method. Although there are many literary sources available that discuss this<br />method, very few of them present its concrete application. This paper presents the application of the mentioned method, along with appropriate equations, at a basic level of analysis. The relevant fracture mechanics parameters are determined numerically using<br />Ansys software, with the example of a thick-walled pressure vessel with cracks in the support zone. The analysis takes into account the effects of operational loads, as well as residual stresses resulting from welding.</p>

<p>Dieser Beitrag hat zum Ziel, die Frage zu beantworten, ob der Konjunktiv als Verbmodus in der deutschen Sprache heute lebendig ist und gem&auml;&szlig; den grammatikalischen Regeln, insbesondere in seiner typischen Verwendung in der indirekten Rede, verwendet wird oder, wie im sprachwissenschaftlichen Diskurs der letzten Jahrzehnte oft behauptet, zum Aussterben bedroht ist. Die Recherche erfolgte anhand ausgew&auml;hlter Zeitungsartikel aus den zwei &uuml;berregionalen repr&auml;sentativen deutschen Zeitungen. Bewusst wurden zwei Textsorten, Bericht und Nachricht, ausgew&auml;hlt, mit dernnahme, dass der Konjunktiv nur in Bericht vorkommt, in Nachricht jedoch weniger oder gar nicht. Die detaillierte Analyse des Gebrauchs und der Funktion des Konjunktivs I und Konjunktivs II im Korpus hat gezeigt, dass die Verwendung des Konjunktivs in den beiden Textsorten gleichm&auml;&szlig;ig und sehr lebendig ist und nach den grammatischen Regeln erfolgt.&nbsp;</p>

This paper analyzes internet memes pertaining to Covid-19. We analyzed more than 200 memes over nine months. By utilizing Blending Theory and Discourse Viewpoint, we attempt to explain the creative inner workings of memes as well as how meaning is negotiated on the internet. We were clearly able to detect memes synchronously following the actual development of Covid-19. We show that meme makers use visuals metonymically to address the current state of Covid-19 while the overall message of memes is driven by simile. As much as memes draw on the concept of Covid-19, they also feed back to it in a loop of self-reference. Along with their underlying metaphoric nature, memes convey a feels-like attitude with two main phases emerging from their usage, i.e., the Observer Phase and the Experiencer Phase. The former showed memes at a stage where Covid-19 was not yet a pandemic (but perceived through media coverage from elsewhere) while the latter, the Experiencer Phase, clearly showed that meme creators had experienced the virus themselves. As for the timeframe covered, however, we conclude that memes do not show full conceptual integration as Covid-19 was not yet fully entrenched.

The main goal of this paper is to point out the concept of creativity in teaching, specifically creativity in the teaching of Nature and Society. Nature and society, as a subject, provide many opportunities to express the creativity that we carry within us through the role of a teacher, as well as to teach students how to be creative. The paper highlights examples of different teaching units that indicate ways to encourage creativity in students and awaken their imagination. Through teaching, through tasks that the teacher creatively devises, we encourage students to think creatively and act, in addition to acquiring knowledge more permanently and functionally. Possibilities of creating Nature and Society lessons through creative examples and experiments, as well as evaluating and measuring creativity, were presented. The work results indicated that creative teachers create their fruits, which are called creative students, that they are causally connected, and that creativity is a synonym for an expert and professional teacher.

The pronoun en is usually described in the literature as an adverbial pronoun, although the adverbial value is only one of several functions in which it can appear. It is a pronoun whose use is very diverse and complex, which is best seen based on numerous syntactic functions that we will present first in this paper. Then we will emphasize the analysis of examples of its use in the corpus, which includes student works divided into three stages (PI / INT / AH). Our goal is to determine to what extent this pronoun is represented in the mentioned corpus and in which syntactic functions it appears most often, i.e., to what extent students master its use. The analysis will also include those examples in which the use of this pronoun was absent as well as those in which its use is unacceptable.

By asking the question: "What general, testable claims can be made about all media?", Marshall and Eric McLuhan (1988) sought to establish "laws of media" that could be tested, proven, or disproved by anyone, anywhere, anytime. They formulated these "laws" through four questions that can be asked upon the appearance of or regarding any human artifact/technology/media. The importance of this theory is indisputable insofar as its application can identify past, current, and at least partially predict future trends related to some human artifact/technology/media. In this paper we applied this theory to the websites/services for social networking, considering the increasingly widespread and intensive use of these sites/services in the world. Positive aspects are improved and accelerated communication and connection of people, opportunities for creative expression, association and struggle for common goals, and also earnings. The negative aspects range from a potentially bad impact on the user's mental health, pathological addiction, the increasingly difficult distinction between the real and virtual world, being trapped by filter bubbles, all the way to endangering personal data and security.

The topic is romantic travelogues with the subject of Bosnia: descriptions andinsights into the perceived “reality” of the Bosnian area and people of the19th century presented through linguistic and stylistic means and on examples of selected travelogues from that period. New historical experiences of the writer opened the way for the emotional reception of collective practices of people, and this often leads to ahistorical conceptualization and long-lasting stereotypes. Considering that both linguistic activity and historical memory are mutual psychological processes, the diverse strategic character of the travel discourse through research shows that known cultural patterns can often deceive with their simplified form.

Traumatic arteriovenous fistula (AVF) is not a common disorder, and dermatological signs and heart failure caused by AVF are rarely reported. We present the case of a 55-year-old woman who was referred for congestive heart failure symptoms. Echocardiography revealed preserved left ventricular ejection fraction. Due to edema of the right leg with a long-standing leg ulcer and palpable femoral thrill, duplex ultrasonography was performed. It showed an AVF between the right superficial femoral artery (SFA) and the right femoral vein (FV). The patient recalled a 32-year-old gunshot injury that was not medically treated. After the diagnosis of AVF she was referred to a surgeon for an AVF ligation, with subsequent resolution of her symptoms. The differential diagnosis of leg ulcer with leg edema should include the possibility of AVF as a cause.

While 5G networks are still being developed and expanded around the world, the industry is already thinking about the next generation to meet the needs of the accelerated digital transformation and the demands of modern society. 6G networks will be even faster, more reliable, with lower latency and higher capacity than their predecessors. It is expected to deliver incredible data transfer speeds of terabytes per second, enabling instant downloads of large files and supporting technologies such as virtual and augmented reality, artificial intelligence, autonomous vehicles, Internet of Things (IoT) devices and other advanced applications.. One key features of 6G networks will be greater connectivity between people, machines and things, creating an intelligent network that will enable highly sophisticated communication scenarios. 6G networks are expected to provide the possibility of continuous connectivity with high quality of service, even in difficult environments such as rural areas, inside buildings or in motion. 6G networks will use multiple frequency bands, including terahertz frequencies, which will allow for greater capacity and higher data transfer speeds. It will also require advanced use of antenna systems, such as massive multiplexed antennas (Massive MIMO), in order to achieve a high degree of wireless efficiency. However, it is important to note that the 6G network is still in the research and development phase. Standardization and commercial implementation are expected only after 2030.
