Der wachsende Einfluss der Internetplattformen des 21. Jahrhunderts in wirtschaftlicher, gesellschaftlicher und politischer Hinsicht hat eine Diskussion über die angemessene Regulierung dieser ...Konzerne ausgelöst. Im Zentrum dieser Debatte steht das Kartellrecht – das Rechtsgebiet, das zur Kontrolle marktbeherrschender Unternehmen geschaffen wurde. Die Bestimmung des im Kartellrecht fundamentalen Begriffes der marktbeherrschenden Stellung steht in der Rechtsanwendung bei Internetplattformen vor zahlreichen Herausforderungen, von der Unentgeltlichkeit der Leistungen bis hin zur Mehrseitigkeit der Geschäftsmodelle. Die vorliegende Arbeit zerlegt den Begriff der marktbeherrschenden Stellung in seine Teile und zeigt auf, inwiefern die Methodik einer Anpassung an die digitale Wirtschaft bedarf. Dies geschieht unter Einbeziehung der Erkenntnisse der Rechtsökonomie sowie der Rechtsordnungen Deutschlands, der Europäischen Union und der USA.

E-learning is a complex system which includes distance learning, lectures,
and classroom materials in various electronic forms; both individual and
group learning process, tutor and interactive work. ...A significant and rapid
increase in the number of users, services, educational content and resources
required, face educational institutions and their e-learning systems with new
challenges of optimization of singling resources out, with the demands of
dynamic competitiveness and with the control of expenses of such systems. All
this leads to the fact that the demands for development and implementation of
IT infrastructure for e-learning systems are becoming more complex. By
applying modern information and communication technologies, it is possible to
increase efficiency, flexibility and cost-effectiveness of e-learning
systems. Through introducing models of IT infrastructure for e-learning based
on a contemporary IT concept of Cloud Computing, the reliability, scalability
and cost-effectiveness of a system of educational processes could be
improved. Insufficient development of scientific support in the application
of the Cloud Computing concept in modeling the IT infrastructure of higher
education of the Republic of Serbia and the strategic importance of this
concept indicates the need to establish theoretic support for its more
efficient development and application. With regards to this, the subject of
the dissertation research is presented, based on defining and development of
plans and activities of higher education institutions, related to the
development of IT infrastructure model for e-learning by means of Cloud
Computing concept. Through examining the existing and searching for new ways
of providing services to students and scientific research staff, higher
education institutions are faced with a significant number of challenges,
mainly regarding digital identity and access management. The first and
probably the greatest challenge is to prompt adoption and implementation of
digital identity management systems. Successful IT infrastructure for digital
identity management requires systematic thinking about identities and
interdependence which exists between them. The second challenge is to provide
support for a system which would be able to use all advantages of federation
systems for digital identities management. The development of such
federations among educational institutions enables mobility of users, content
and services. The main hypothesis devised and proven within the doctoral
thesis is that the application of a developed IT infrastructure model can
influence the efficiency and cost-effectiveness of e-learning systems. The
experimental part of the doctoral thesis is consisted of a research, directed
towards the validation of the proposed IT infrastructure model for
e-learning. Research was conducted in the Laboratory for E-Business at the
Faculty of Organizational Sciences. The results of the research showed that
the implemented model of IT infrastructure enabled the system of e-learning
to be more efficient, flexible and more economical.
Elektronsko obrazovanje je kompleksan sistem koji uključuje učenje na
daljinu, predavanja na daljinu, nastavne materijale u raznim elektronskim
formama, individualni i grupni proces učenja, tutorski i interaktivni rad.
Ogroman i brzi rast broja korisnika, usluga, obrazovnih sadržaja i potrebnih
resursa, suočavaju obrazovne ustanove i njihove sisteme elektronskog
obrazovanja sa izazovima optimizacije izdvajanja resursa, zahtevima dinamičke
konkurentnosti i sa kontrolom troškova ovakvih sistema. Sve ovo dovodi do
toga da su zahtevi za projektovanje i implementaciju IT infrastrukture
sistema za elektronsko obrazovanje sve kompleksniji. Primenom savremenih
informaciono-komunikacionih tehnologija moguće je doprineti povećanju
efikasnosti, fleksibilnosti i ekonomičnosti sistema za elektronsko
obrazovanje. Uvođenjem modela IT infrastrukture za elektronsko obrazovanje,
zasnovanog na savremenom IT konceptu Cloud Computing-a, mogu se unaprediti
obrazovni procesi sa stanovišta pouzdanosti, skalabilnosti i ekonomičnosti
sistema. Nedovoljno razvijena naučna podrška primene koncepta Cloud
Computing-a u modelovanju IT infrastrukture u visokoškolskom obrazovanju
Republike Srbije i strateška važnost ovog koncepta, ukazuje na potrebu
postavljanja teorijske podrške njegovog efikasnijeg razvoja i primene. U tom
smislu je i predstavljen predmet istraživanja disertacije, koji se bazira na
definisanju i razvijanju planova i aktivnosti visokoškolskih ustanova,
vezanih za razvoj modela IT infrastrukture za elektronsko obrazovanje pomoću
Cloud Computing koncepta. Preispitujući postojeće i tražeći nove načine
pružanja usluga studentima i naučno-istraživačkom osoblju, visokoškolske
ustanove se suočavaju sa velikim brojem izazova uglavnom oko digitalnog
identiteta i upravljanja pristupom. Prvi i možda najveći izazov je kako da se
podstakne usvajanje i implementacija sistema za upravljanje digitalnim
identitetom. Uspešna IT infrastruktura za upravljanje digitalnim identitetom
zahteva celovito razmišljanje o identitetima i međuzavisnostima koje između
njih postoje. Drugi izazov je izgradnja podrške za sistem koji će moći da
iskoristi sve prednosti saveza sistema za upravljanje digitalnim
identitetima. Stvaranjem ovakvih saveza između obrazovnih ustanova obezbeđuje
se mobilnost korisnika, sadržaja i usluga. Glavna hipoteza koja je razvijena
i dokazana u okviru doktorske disertacije je da se primenom razvijenog modela
IT infrastrukture može uticati na efikasnost i ekonomičnost sistema za
elektronsko obrazovanje. U eksperimentalnom delu doktorske disertacije
realizovano je istraživanje usmereno ka validaciji predloženog modela IT
infrastrukture za elektronsko obrazovanje. Istraživanje je sprovedeno u
Laboratoriji za elektronsko poslovanje Fakulteta organizacionih nauka.
Rezultati istraživanja pokazali su da implementirani model IT infrastrukture
omogućava da sistem za elektronsko obrazovanje bude efikasniji, fleksibilniji
i ekonomičniji.

The availability of modern information and communication technology has
significantly impacted the process of learning and teaching, as well as the
process of education strategy creation. Hence, the ...vast majority of
educational institutions and communities propose electronic education as one
of the emerging research trends in the education process development. Having
in mind that every education strategy bears certain risks, it is necessary to
design electronic education models in order to avoid potential complications
and maximize the benefits of the strategy. In order to enhance learning and
teaching efficiency, educational process needs to be enriched with modern
interactive content that stimulates students to actively participate in the
education process. Edutainment represents one of the prevailing methods that
enhance students’ active participation in the education process. The research
topic of the dissertation is the development of the edutainment model in
electronic education. The main hypothesis developed and proved in the
dissertation is that the implementation of the edutainment model in
electronic education enhances the performances and the quality of the
educational process, quality of communication and collaboration processes
between students and the educational institution, and achieves higher levels
of students’ satisfaction. Edutainment refers to a hybrid education method
that uses fun multimedia-based activities for materializing educational
activities. The process of electronic education is often supported by
Learning Management Systems (LMS). Moodle LMS is the most frequently used
software solution for managing educational materials and it serves as a
platform that integrates all implemented units of the dissertation. The
analysis of the existing learning management system served as a basis for
defining the structure of the proposed edutainment model in electronic
education. The base elements of the proposed model include defined goals,
preferences, motivation and needs of every student. The proposed edutainment
model in electronic education comprises the infrastructure, the edutainment
system architecture, and process of introducing edutainment into electronic
education and edutainment services. In the experimental part of the doctoral
thesis, the proposed edutainment model in electronic education was developed
and implemented in the educational process. Edutainment modules for Moodle
LMS were applied. Edutainment services on social networks and mobile
edutainment services were integrated with Moodle LMS. The listed services
were implemented and applied in the educational process in the Laboratory for
e-business of the Faculty of Organizational Sciences. Following the
implementation and application of the aforementioned services, research was
conducted in order to validate the proposed model. The research results
showed that the edutainment model application in electronic education
improved the learning process, as well as that the students consider that
this method of education suited their needs. The most significant scientific
contribution of the dissertation is the edutainment model in electronic
education development. The model provides simple and efficient changes and
adjustments for use in different environments. The model is suitable for
application in the higher education institutions in Serbia.
Dostupnost savremenih informaciono-komunikacionih tehnologija znatno je
uticala na proces učenja i podučavanja, kao i na način kreiranja strategija
obrazovanja. Elektronsko obrazovanje jedan je od dominantnih pravaca razvoja
procesa obrazovanja u velikom broju obrazovnih institucija i zajednica.
Imajući u vidu da svaka strategija obrazovanja sa sobom nosi određene rizike,
neophodno je dizajnirati modele elektronskog obrazovanja kako bi se izbegli
potencijalni problemi i maksimizirale prednosti strategije. Kako bi se
povećala efikasnost učenja i podučavanja, obrazovni proces je neophodno
obogatiti atraktivnim interaktivnim sadržajem, koji studente uključuje u
proces obrazovanja kao aktivne učesnike. Učenje kroz igru predstavlja jednu
od savremenih metoda obrazovnog procesa koja doprinosi aktivnom učešću
studenata u procesu obrazovanja. Predmet istraživanja doktorske disertacije
jeste razvoj modela učenja kroz igru u elektronskom obrazovanju. Glavna
hipoteza koja je razvijena i dokazana u okviru doktorske disertacije jeste da
se implementacijom modela učenja kroz igru u elektronsko obrazovanje
poboljšavaju performanse i kvalitet obrazovnog procesa, kvalitet komunikacije
i saradnje između studenata i obrazovne institucije i postigne veće
zadovoljstvo studenata. Učenje kroz igru (edutainment) se odnosi na hibridni
metod obrazovanja koji koristi zabavne aktivnosti zasnovane na multimediji za
realizaciju edukativnih aktivnosti. U procesu elektronskog obrazovanja često
se upotrebljava sistem za upravljanje učenjem (Learning Management System-
LMS). Moodle LMS je najčešće korišćeno softversko rešenje za upravljanje
obrazovnim materijalima koje integriše sve realizovane celine doktorske
disertacije. Na osnovu analize postojećeg sistema za upravljanje učenjem,
definisana je struktura predloženog modela učenja kroz igru u elektronskom
obrazovanju. Kaopolazni osnov za izgradnju modela definisani su ciljevi,
preferencije, motivacija i potrebe svakog studenta. Predloženi model učenja
kroz igru u elektronskom obrazovanju obuhvata infrastrukturu, arhitekturu
sistema učenja kroz igru, proces uvođenja učenja kroz igru u elektronsko
obrazovanje i servise učenja kroz igru. U eksperimentalnom delu doktorske
disertacije predloženi model učenja kroz igru u elektronskom obrazovanju
razvijen je i implementiran u nastavnom procesu. Primenjeni su moduli za učenje
kroz igru u Moodle LMS, a edutainment servisi na društvenim mrežama i mobilni
edutainment servisi integrisani su sa Moodle LMS-om. Navedeni servisi
primenjeni su u nastavnom procesu u Laboratoriji za elektronsko poslovanje
Fakulteta organizacionih nauka. Rezultati istraživanja pokazali su da primena
modela učenja kroz igru unapređuje proces učenja, i da studenti smatraju da im
ovakav vid obrazovanja izuzetno odgovara. Najznačajniji naučni doprinos
doktorske disertacije jeste razvoj modela učenja kroz igru u elektronskom
obrazovanju. Model se može jednostavno i efikasno menjati i prilagođavati za
primenu u različitim okruženjima, a pogodan je za primenu u visokoškolskim
ustanovama u Srbiji.
