D-vitamiinid e. kaltsiferoolid on rasvlahustuvate vitamiinide rühm, mis käituvad inimorganismis hormoonide sarnaselt. Tuntumad D-vitamiini vormid on loomse päritoluga D3 e. kolekatsiferool ja taimse päritoluga D2 e. ergokaltsiferool. 90 % inimkehas olevast D-vitamiinist tekib ultraviolettkiirguse toimel nahapinnale. Vaid 10-20 % saame loomse päritolu toidu kaudu ning ainult umbes 1% taimsete toiduainetega. D-vitamiini puuduse profülaktikaks kasutatakse veel lisamanustamist kapslite või õlina. D-vitamiini sisaldust hinnatakse inimekehas kaudselt 25(OH)D määramisega vereseerumis. D-vitamiini defitsiit on väga leivunud probleem, kuid ikkagi tuleb see sageli üllatusena, sest ka pikaajaline defistiit ei põhjusta enamikel inimestel tuntavaid füüsilis vaeguseid. D-vitamiini on väga oluline luu metabolismis ning defitsiidi tingimustes tõuseb risk osteopeeniale ja osteoporoosile, luumurdudele, stressmurdudele ning lisaks immunsüsteemi funktsionihäiretele ja füüsilise töövõime langusele. D-vitamiini defitsiiti risk esineb kõigis vanusegruppides ning tõuseb väga suure füüsilise ja vaimse koormusega seotud tegevusaladel, mille hulka kuulub ka sõjaväeteenistus. Füüsiline võimekus on sõjaväes kriitilise tähtsusega nii väljaõppel kui ka missioonidel. D-vitamiiniga seotud uuringud näitavad vastukäivaid seoseid füüsilise võimekuse ja D-vitamiini defistiidi vahel. Uuringu eesmärgiks oli hinnata D-vitamiini tasemeid erinevatel aastaaegadel, lisamanustamise mõju ja seoseid füüsilisele võimekusega Eesti ajateenijatel. Uuringute käigus leidsime D-vitamiini defitsiiti juba suvekuudel ning olulist süvenemist kevadeks. Madalates annustes (kuni 1200IU) pikaajaline D-vitamiini profülaktika ei tõstnud vereseerumi 25(OH)D erinevalt 4000IU manustamisega, kus efekt oli selgelt positiivne. Sama uuringu käigus teostatud füüsilisse võimekuse testidel ei leitud uuringurühmades seoseid D-vitamiini defitsiidi ja füüsilise võimekuse vahel. Doktoritöö tulemusena saame anda uusi soovitusi D-vitamiini defitsiidi profülaktikaks noortel meestel.
Cross-Border Mobile Government Services: Exploring Business Model Dynamics in mGov4EU
(Springer Cham, 2024-11-14) Lampoltshammer, Thomas J.; Sellung, Rachelle; Dedovic, Stefan
The mGov4EU project represents an ambitious effort to revolutionise European mobile government services. It aims to develop an ecosystem that integrates state-of-the-art digital wallet approaches within the framework of eIDAS and SDG. This initiative is pivotal in fostering a seamless interface between citizens, businesses, and public administrations, enhancing the efficiency and user experience in accessing government services. Despite its potential, the mGov4EU project confronts many challenges, including legal compliance, technical interoperability, user acceptance, and the formulation of viable and sustainable business models. These challenges are particularly pronounced in the public sector, where traditional business strategies may not align seamlessly with innovative digital service models. This chapter focuses on examining the business model aspects of the mGov4EU project. It explores the strategies and priorities of the project’s partners, particularly in the context of sustaining and scaling the project outcomes within the European framework. It reflects on decisions, as well as challenges accordingly.
Sustainability and Governance of the mGov4EU Project
(Springer Cham, 2024-11-14) Schmidt, Carsten; Dedovic, Stefan
Sustainability and governance of the mGov4EU project are critical for its long-term success, particularly in transforming public services and streamlining administrative processes. The mGov4EU project, aiming to design user-centric solutions and enhance cross-border digital public services, places sustainability and governance at the forefront. This involves meticulous outcomes analysis, focusing on pilots and architecture, considering legal frameworks, stakeholder involvement, financial models, and developmental status. The exploration of cross-border mobile government factors reveals consistent determinants across various typologies, encompassing technology, innovation, public officials, citizens, organi-sations, institutions, public sector context, and broader environmental factors. The multifaceted influences on digital governance initiatives underscore the complex nature of the mGov4EU project. This chapter delves into the piloting impact assessment, analysing design and execution phases. The assessment is crucial for shaping a sustainability plan, recognising core results requiring sustained focus, and identifying areas for improvement. The GOFA model (Governance, Operations, Finance, and Architecture) and Objectives and Key Results (OKR) methodology are applied for a detailed analysis of project outcomes, ensuring a thorough understanding of challenges and requirements for long-term success. The goal is to establish a robust foundation for sustainability and governance, introducing the GOFA model and OKR analysis to navigate the complex landscape of mGov4EU outcomes. The integrated approach ensures a thorough understanding of challenges and requirements essential for long-term success. Challenges across pilots and architecture are addressed, focusing on stakeholder involvement, take-up, flexibility, and continuity. Co-creation principles are integrated into different project stages, fostering collaboration and engagement with various stakeholders. A transdisciplinary context is integrated into the impact assessment, and the GOFA model is employed for sustainability and governance. The co-creation principle is a recurring theme, engaging stakeholders in ongoing project development and execution. In general, the mGov4EU project, emphasising sustainability and governance, presents a holistic approach to address the complexities of cross-border digital public services, ensuring long-term success and impactful outcomes.
Future Outlook and Research Ideas
(Springer Cham, 2024-11-14) Lampoltshammer, Thomas J.; Leitold, Herbert; Schmidt, Carsten; Zefferer, Thomas
This chapter uses the lessons learned from technical work and piloting of the mGov4EU project, as well as experience made so far in developing the Single Digital Gateway (SDG) Once-Only Technical System (OOTS) and the European Digital Identity Wallet (EUDIW). These are our basis, and we dare to look into the future. The two European flagship policy initiatives OOTS and EUDIW are meant to facilitate citizens’ journey through European public services but also are meant as tools to navigate private services in the Digital Single Market. It, however, would be naïve to assume that setting such complex systems into production is the end of an endeavour. We might only learn through first experience where pitfalls lie but in particular what opportunities are given that haven’t been seen before. We, therefore, give authors’ views on where this road might lead us and what research might be essential to get there. The chapter, thus, aims at anticipating what might be needed to reap the benefits of OOTS and EUDIW in a mobile world from a governance perspective, a privacy and data protection perspective, a services perspective and a mobile technologies perspective. Therefore, each section first sets the scene by outlining the status. This is followed by addressing some challenges and gives an outlook by indicating how research might address these challenges.
Introduction
(Springer Cham, 2024-11-14) Lampoltshammer, Thomas J.; Solvak, Mihkel; Homburg, Vincent
This chapter introduces some technological and policy developments that are at the heart of the mGov4EU project. In the mGov4EU project, various pilots implement and validate enhanced infrastructure services for electronic voting, smart mobility and mobile signing, using mobile devices most of us nowadays naturally expect as a default way of accessing services. The pilots aimed to demonstrate the feasibility of providing cross-border information to enhance cross-border mobility and cross-border collaboration in the European Union. The pilots also demonstrated how enhanced electronic identities and trust services (eIDAS) and Single Digital Gateway Regulation (SDGR) layers can accommodate once-only, digital-by-default and mobile-first principles. For this to result in user-centric, user-friendly mobile public services, stakehold-ers’ roles (including but not limited to end users’ experiences and requirements) have to be identified, architecture core building blocks have to be assembled, implementations have to align with EU eIDAS and SDG regulations and, with the eSignature interoperability system and the Digital Wallet System, ethics, security and privacy requirements have to be taken into account and evaluated. The long-term viability has to be ensured. This first chapter briefly introduces all these relevant angles and describes how the various chapters will focus on how specific challenges were tackled and what lessons learnt could be drawn.
