Ziel dieses Ratgebers ist es, die für Unternehmensgründer relevanten juristischen Aspekte aufzuzeigen und diese hierfür zu sensibilisieren. Während Ratgeber zur Ideengewinnung, zur Vermarktung oder auch zu Finanzierungsfragen relativ häufig zu finden sind, werden die rechtlichen Rahmenbedingungen kaum beleuchtet. Dabei weisen die Komponenten eines Start-up-Marketing unterschiedliche Schwerpunkte und Vertiefungsgrade zum traditionellen Marketingauf. Dieses wird im vorliegenden Ratgeber auch im Hinblick auf die rechtlichen Rahmenbedingungen berücksichtigt.
Zu Beginn steht die Innovation oder die Geschäftsidee im Mittelpunkt. Diese sowie eine damit verbundene Marke gilt es zu schützen. Weitere zentrale Anfangsüberlegungen betreffen die zu wählende Rechtsform. Wichtige Aspekte sind zudem aus rechtlicher Sicht die Verträge mit den Investoren und diejenigen Rechtsfragen, die mit dem Internet verbunden sind, vor allem der Onlinevertrieb oder die Social-Media-Nutzung. Bei der Vermarktung seiner Leistungen muss ein Start-up-Verantwortlicher rechtliche Fragen möglichst proaktiv berücksichtigen sowie darauf achten, dass sein Verhalten im Wettbewerb nicht durch unlauteres Handeln geprägt wird.
Dieser Ratgeber orientiert sich bei der Vorstellung der rechtlichen Rahmenbedingungen am Ablauf des Gründungsprozesses eines Start-ups:
➢ Anmeldung,
➢ Schutz der Geschäftsidee,
➢ Wahl der Rechtsform und
➢ Marketingaktivitäten.
Despite increasing budgets for social media activities and a wide variety of performance measurement possibilities, many companies do not measure the performance of their social media activities. Research shows that those companies that measure the performance of social media activities use incorrect, too few or inappropriate metrics. A central problem is that there is often an inadequate performance measurement process. This article presents a process that focuses on the objectives of social media activities. In phase one of this process, suitable metrics are selected and target values are defined based on these objectives. In phase two, data are collected and analysed. Finally, actions are defined. The developed process helps companies to measure the performance of their social media activities.
Digital, virtual environments and the metaverse are rapidly taking shape and will generate disruptive changes in the areas of ethics, privacy, safety, and how the relationships between human beings will be developed. To uncover some of some of the implications that will impact those areas, this study investigates the perceptions of 101 younger people from the generations Y and Z. We present a first exploratory analysis of the findings, focusing on knowledge and self-perception. Results show that these young generations are seriously doubting their knowledge on the metaverse and virtual worlds – regarding both the definition and the usage. It is interesting to see only a medium confidence level, considering that the participants are young and from an academic environment, which should increase their interest in and the affinity towards virtual worlds. Males from both generations perceive themselves as significantly more knowledgeable than females. Regarding a fitting definition, almost 40% agreed on the metaverse as a “universal and immersive virtual world that is made accessible using virtual reality and augmented reality technologies”. Regarding the topic in general, several participants (almost 40%) considered themselves sceptics or “just” users (38%). Interestingly, generation Y participants were more likely than the younger generation Z participants to identify themselves as early adopters or innovators. In result, the considerable amount of “mixed feelings” regarding digital, virtual environments and the metaverse shows that in-depth studies on the perception of the metaverse as well as its ethical and integrity implications are required to create more accessible, inclusive, safe, and inclusive digital, virtual environments.
Activities for rehabilitation and prevention are often lengthy and associated with pain and frustration. Their playful enrichment (hereafter: gamification) can counteract this, resulting in so-called “exergames”. However, in contrast to games designed solely for entertainment, the increased motivation and immersion in gamified training can lead to a reduced perception of pain and thus to health deterioration. Therefore, it is necessary to monitor activities continuously. However, only an AI-based system able to generate autonomous interventions could vacate the therapists’ costly time and allow better training at home. An automated adjustment of the movement training’s difficulty as well as individualized goal setting and control are essential to achieve such autonomy. This article’s contribution is two-fold: (1) We portray the potentials of gamification in the health area. (2) We present a framework for smart rehabilitation and prevention training allowing autonomous, dynamic, and gamified interactions.
In den letzten Jahren haben Recommender Systeme zunehmend an Bedeutung gewonnen. Diese Systeme sind meist für Bereiche des E-Commerce konzipiert und berücksichtigen oftmals nicht den aktuellen Kontext der nutzenden Person. Recommender Systeme können allerdings nicht nur im E-Commerce zum Einsatz kommen, sondern finden ihren Anwendungszweck auch im Gesundheitswesen. Ziel dieser Bachelorarbeit ist es, ein Recommender System zu entwickeln, das den aktuellen Kontext der nutzenden Person (Chatverlauf, demografische Daten) besser berücksichtigen kann. Dazu befasst sich diese Arbeit mit der Konzeption und prototypischen Umsetzung eines kontextsensitiven Recommender Systems für einen bereits existierenden Chatbot aus dem Gesundheitswesen. Das in dieser Arbeit konzipierte und entwickelte Recommender System soll Mitarbeitende aus dem Gesundheits- und Sozialwesen entlasten und ihnen hilfreiche sowie thematisch sinnvolle Informationen zur Verfügung stellen. Basierend auf festgelegten Anforderungen wurde ein Konzept für das Recommender System entwickelt und zu Teilen als Prototyp umgesetzt. Abschließend wurde der Prototyp im Hinblick auf die Anforderungen evaluiert. Zudem fand eine technische Evaluation und eine Evaluation mithilfe von Anwendenden statt, welche den implementierten Prototypen bereits existierenden Systemen gegenüberstellte. Die von dem Prototyp empfohlenen Textausschnitte erzielten in der Evaluation mit nutzenden Personen eine thematisch signifikant höhere Übereinstimmung mit den Chatdaten.
Objective: Dickkopf 3 (DKK3) has been identified as a urinary biomarker. Values above 4000 pg/mg creatinine (Cr) were linked with a higher risk of short-term decline of kidney function (J Am Soc Nephrol 29: 2722–2733). However, as of today, there is little experience with DKK3 as a risk marker in everyday clinical practice. We used algorithm-based data analysis to evaluate the potential dependence of DKK3 in a cohort from a large single center in Germany.
Method: DKK3 was measured in all CKD patients in our center October 1 st 2018 till Dec. 31 2019, together with calculated GFR (eGFR) and urinary albumin/creatinine ratio (UACR). Kidney transplant patients were excluded. Until the end of follow-up Dec 31 st 2021, repeated measurements were performed for all parameters. Data analysis was performed using MD-Explorer (BioArtProducts, Rostock, Germany) and Python with multiple libraries. Linear regression models were applied in patients for DKK3, eGFR and UACR. Comparison of the models was performed with a twosided Kolmogorov-Smirnov test.
Results: 1206 DKK3 measurements were performed in 1103 patients (621 male, age 70yrs, eGFR 29,41 ml/min/1.73qm, UACR 800 mg/g). 134 patients died during follow-up. DKK3 mean was 2905 pg/mg Cr (max. 20000, 75 % percentile 3800). 121 pts had DKK3 > 4000. At the end of follow-up 7 % of patients with DKK3 < 4000 (initial eGFR 17.6) versus 39.6 % of patients with DDK3 > 4000 (initial eGFR 15.7) underwent dialysis. Compared to eGFR and UACR at baseline, DKK3 > 4000 performed best to predict eGFR loss over the next 12 months.
Conclusion: In this cohort of CKD patients, DKK3 > 4000 at baseline predicted the eGFR slope better than eGFR or UACR at baseline. DKK3 > 4000 reflected a higher risk of progression towards ESRD in patients with similar baseline eGFR levels.
This thesis evaluates and compares current Full-Stack JavaScript Technologies. Through extensive research on the state of the art of JavaScript and its related frameworks, different aspects of FullStack Development are analysed to judge the popularity of technologies.
The language JavaScript and the idea of Full-Stack Development are presented with the functionality of different frameworks. The JavaScript runtime Node.js was examined and marked as the most influential JavaScript technology, which opened up many opportunities.
As technology stacks MERN, MEAN and MEVN were investigated, featuring the base technologies Node.js, MongoDB and Express.js. It was discovered that front-end frameworks have the most influence on which variant of Full-Stack can be chosen. Comparison criteria between the technology stacks were the learning curve, the maintainability, modularity and media integration. These criteria were extracted from research and a questionnaire conducted with students of the University of Applied Sciences Offenburg.
For the purposes of testing and experiencing a Full-Stack JavaScript application, the game RemArrow, based on the 1979s game Simon, was designed and implemented. The comparison with predefined criteria shows the result that the MERN stack with React.js is the best to learn and promises the most potential. Arising JavaScript technologies and their popularity are very dependent on the industry and skill set of the developer.
In conclusion, it can be established that the concept of Full-Stack Development is currently very interesting and more than just a trend. It has potential of becoming a new kind of web development, and part of the curriculum taught at universities. Expert knowledge is needed but there is a high demand and much potential for Full-Stack JavaScript Developers.
VR-based implementation of interactive laboratory experiments in optics and photonics education
(2022)
Within the framework of a developed blended learning concept, a lot of experience has already been gained with a mixture of theoretical lectures and hands-on activities, combined with the advantages of modern digital media. Here, visualizations using videos, animations and augmented reality have proven to be effective tools to convey learning content in a sustainable way. In the next step, ideas and concepts were developed to implement hands-on laboratory experiments in a virtual environment. The main focus is on the realization of virtual experiments and environments that give the students a deep insight into selected subfields of optics and photonics.
