Abstract: This textbook introduces Oracle Application Express (APEX), a low-code platform for building data-driven web applications. It aims to equip readers with the skills to fully utilize APEX for real-world business challenges. Part I covers the basics of APEX in twelve chapters, including environment setup, database preparation, navigation, data exchange, application creation, report and form management, and team collaboration. Part II presents twelve business cases that provide a comprehensive understanding of application development from a business, data, and user interface perspective. Each case includes business views, problem definitions, use cases, data models, and application interfaces. The textbook is designed for approximately 75 hours of study and is suitable for both experienced developers and beginners. It includes additional material such as exported applications, scripts, data and video tutorials to enhance learning.
Keywords: low-code programming, application development, web applications, Oracle APEX, practical examples

Abstract: Mobile devices, seamlessly weaving artificial intelligence into their applications, have become indispensable for millions of people in their daily lives. In our master’s thesis, we explored methods for evaluating user experience, focusing on those suitable for modern mobile applications. In the applied phase, participants evaluated three mobile apps using distinct questionnaires. This affirmed the positive correlation between user interface simplicity and enhanced UX, alongside modern interaction methods fostering increased user loyalty. Our findings confirm that post-task questionnaires offer deeper insights into UX, with users showing a preference for completing them. While gender may influence user experience, it's not the sole determinant.

Abstract: Raziskava temelji na projektu, katerega namen je bil upravljanje identitet na imeniškem strežniku (OpenLDAP) s pomočjo spletne aplikacije, izdelane v orodju Oracle application Express (APEX). V tem primeru baza podatkov Oracle služi kot primarni vir za vzdrževanje imenika uporabnikov. Na kratko so prikazane značilnosti imeniških strežnikov, ki uporabljajo protokol LDAP, ter primer odprtokodne rešitve OpenLDAP. Opisane so nekatere lastnosti baze podatkov Oracle, sistemskega paketa DBMS_LDAP ter malokodnega orodja za razvoj spletnih aplikacij APEX. V eksperimentalnem delu so prikazani priprava razvojnega okolja z dvema virtualnima strojema (APEX in OpenLDAP), paket PIIS_SYNC, ki uporablja funkcije DBMS_LDAP, ter spletna aplikacija za upravljanje zapisov v strežniku LDAP. V nalogi so bile nekatere funkcije paketa DBMS_LDAP preizkušene v testnem okolju, vendar bi ob primerni zaščiti omrežnega prometa paket lahko prenesli tudi v produkcijsko okolje.

Abstract: Article discuss the impact of the Brussels I and Brussels I bis Regulations on Slovenian enforcement proceedings. The aim of the Brussels I bis Regulation is to ensure creditors a simpler but mostly quicker access to enforcement in case a judgment must be enforced in a state other than the Member State of origin. The new regulatory framework will certainly facilitate quicker access to enforcement for creditors. However, this can only be ensured categorically in the first phase of enforcement, i.e. the seizure of assets (distraint). In subsequent enforcement phases successful enforcement in favour of the creditor could be stayed if the debtor decides to enforce grounds used to challenge the enforceability of a foreign judgment. A major distinction is that the control of enforceability will only proceed if and when the debtor so requests.Prispevek obravnava vpliv Uredb BU I in BU I bis na slovenski izvršilni postopek. Namen BU I bis je upniku zagotoviti lažji, predvsem pa hitrejši dostop do izvršbe v primeru, da je treba sodbo izvršiti v drugi državi kot v državi izvora. Gotovo bo nova ureditev upniku zagotovila hitrejši dostop do izvršbe, vendar to lahko kategorično zagotovimo le za prvo fazo izvršbe, to je rubež premoženja. V kasnejših fazah izvršitve pa se utegne upniku uspešna izvršba odložiti, če se dolžnik odloči uveljavljati razloge, s katerimi bo nasprotoval izvršljivosti tuje sodne odločbe. Pomembna razlika je ta, da se bo kontrola izvršljivosti opravila le ko in če bo dolžnik to zahteval.

Abstract: Nowadays, traditional sources are mostly used for energy production, such as fossil and nuclear fuels. Such energy sources have a negative impact on the environment. As a result, trends in energy production are increasingly focused on renewable energy sources. These energy sources are available everywhere and their environmental impact is minimal. Nonetheless, these energy sources cannot be exploited with the same efficiency during the day (the Sun is not present the whole day, in winter, the sunlight days are shorter, the wind is not constant, etc.) or during different periods of the year. The variable amount of energy, produced from these sources and the integration with energy distribution systems, must not be overlooked. This is especially important in power plants, where it is necessary to ensure high energy reserves at excess load, which can be achieved by incorporating an improved energy storage system and higher efficiency of produced electricity. This process contributes to a significant reduction in costs. Direct energy storage systems, described in this master's thesis, are used in applications that require many fast charging and discharging cycles instead of a long-term energy storage in cars, buses, trains and lifts, where they are used for regenerative braking, short-term energy storage or as a primary source of electricity. Supercapacitors are electrochemical double-layer capacitors with low energy density and high power density. They have low series resistance, so they have the ability to emit high current, allowing them to charge quickly and a long lifespan. The goal of the thesis is to determine experimental parameters of supercapacitors and to compare them with theoretical parameters and batteries. With the simulation method of charge and discharge we have proven, that differences in results exists.
