Abstract: This thesis explores the integration of 2D and 3D visual elements in hybrid animation, with a particular focus on their application within the context of virtual reality (VR). The first section presents a theoretical framework, analyzing the characteristics of 2D and 3D elements and examining hybrid animation techniques used in films such as The Peanuts Movie, Soul, and Spider-Man: Into the Spider-Verse. These case studies were applied in the empirical section, in which a 360° animated shot was created in program Blender by blending both animation styles. The project challenges the traditional boundaries between 2D and 3D animation by employing custom shaders, 2D planes for texture mapping, and VR-specific adjustments to provide a seamless viewer experience. The thesis highlights the technical and artistic challenges of integrating these two forms within an immersive environment, offering new insights into the potential of hybrid animation for storytelling in virtual spaces. Future work could explore advancements in VR interactivity and more dynamic 2D-3D integration techniques.

Abstract: Aim: The aim of this study was to perform a systematic literature review of the purpose, design, and use of family trees by family physicians (FPs). Background: Family trees offer a valuable contribution to understanding the relevance of the patient's family history in comprehensive primary healthcare provision. There is little research on the role of family trees in the everyday practice of FPs. Studies often focus on specific diseases and their context: however, a comprehensive exploration of the usefulness of family trees is crucial for FPs. Methods: A systematic literature review was conducted through a keyword search in the PubMed and Cochrane databases. Based on the inclusion and exclusion criteria selected, 24 studies were identified and a qualitative analysis was performed. Findings: A total of 369 publications were identified across 32 fields. Twenty-four studies were included in the final analysis according to the QUOROM statement. The results underscore the role of family trees and highlight the value of this tool's multidimensionality. The use of this tool directs FPs to consider a genetic cause and a possible referral to a geneticist. The value of a family tree lies in the personalized patient-oriented treatment in connection with hereditary risks for chronic diseases. For FPs, the greatest challenge in treating patients is determining their risk of developing a chronic disease or cancer. Using a family tree can improve the quality of their healthcare.

Abstract: Background: The software product lines (SPL) enable development teams to fully address a systematic reuse of shared assets to deliver a family of similar software products. Mobile applications are an obvious candidate for employing an SPL approach. This paper presents our research outcomes, based on empirical data from an industry-level development project. Two development teams were confronted with the same functionalities set to be delivered through a family of native mobile applications for Android and iOS. Methods: Empirical data was gathered before, during and after a year of full-time development. The data demonstrate the impact of a SPL approach by comparing the SPL and non-SPL multiple edition development. One family of products (Android apps) was developed using an SPL approach, while another (iOS apps), functionally the same, was developed without employing an SPL approach. The project generated a volume of raw and aggregated empirical data to support our research questions. Results: The paper reports a positive impact of an SPL approach on product quality (internal and external) and feature output per week. As data shows, it also increases the delivery of functionalities (240% in 6 more editions), while investing the same amount of effort needed for a single-edition development. As a result of system-supported separation of development and production code, developers had a high confidence in further development. On the other hand, the second team delivered less new functionalities, only two new application editions, and lower software quality than the team that manages multi-edition development by employing an SPL approach.

Abstract: Sensing and remembering features in visual scenes are conditioned by visual attention and methods to guide it. This should be relevant in terms of product placement, which has become an important part of incorporating brands into different mass media formats with a commercial purpose. The approach can be challenging in 360◦ video, where an omnidirectional view enables consumers to choose different viewing perspectives, which may result in overlooking the brands. Accordingly, attention guidance methods should be applied. This study is the first to explore diegetic guidance methods as the only appropriate guiding method for an unobtrusive and unconscious nature of product placement. To test the effectiveness of three different diegetic guiding methods, a between-subject design was employed, where the participants were assigned randomly to one of four videos with the same scene but different guiding methods. The findings show and explain the discrepancy with studies on guiding attention in other contexts, as there were no significant differences between the guiding cues according to brand recall and brand recognition. The results also indicate a significant influence of brand familiarity on brand recall in 360◦ video. The article concludes by providing limitations, future research directions, and recommendations for audiovisual policy.
