Combining User Experience Design & Service Design: Theory meets Practice
No full textThis thesis explores how UXD and SD can work together more seamlessly in practice.
UXD and SD have a lot of similarities. This has led to confusion around the borders and overlaps of both fields. Therefore researchers called for more studies to clarify their relationship. Most recent studies suggested diverting from polishing single touchpoints; some studies and focussing on end-to-end journey and the customer.
The thesis examines the underlying activities of existing theoretical approaches and the challenges of combining UXD and SD with the help of thematic analysis. A set of proposed strategies were developed based on a survey on current practices and challenges with practitioners and thematic analysis. As a result, the thesis presents four strategies that design teams can incorporate into their processes.
The idea is to promote the creation of better quality products and services by harnessing the benefits of both fields. The key point was that these concepts are still broad and should be simplified into leaner modes that can be applied in daily activities
NATION BRANDING THROUGH CULTURE EXPORT SYSTEM MODEL. The implicit relationship of the South Korean Government Nation Branding and the Creative Industry: 1990-2021
No full textThis thesis contributed to the fields of Policy Science and Nation Branding by creating a systematic analysis of actors’ behavior, and analyzing in-depth the dynamics of South Korea’s government-related actors who are involved with culture-related strategies. South Korea was used as the base for the modeling, considering its observed success in integrated strategies to promote the countries’ image through culture. The Nation Branding model proposed, has culture as its main driver, focusing on content creation and culture-related collaborations as the main tactic to disseminate culture and information, seeking to leave positive impressions on the foreign public, increasing the country-affinity factor in decision-making. The model's main characteristic is task-focused structuring and flexible boundaries. Defined boundaries and action limitations would preclude collabotrations and similar efforts by different actors. Overlapping efforts in this model are not a waste of energy, as all actors use the same tool: culture; the more positive value each actor can produce regarding culture will be added as a resource to the other actors. The model proposed in this paper is based on only one known strategy, yet, it provides enough information for a starting point; further research of other systems and comparative studies are necessary to develop and test the model
Self-Calibration of lateration-based localization systems
No full textLocalization systems play an essential role in many applications nowadays; they are implemented in industrial, commercial, and even personal applications; it is always essential for some applications to pinpoint the location of a person or an object in space. In this thesis, I focus on lateration-based localization systems consisting of several stationary nodes or stations and several mobile stations or devices. Lateration techniques are used to find the relative distances between the static nodes and the mobile devices, such as time of arrival (TOA), time difference of arrival (TDoA), and round-trip time (RTT).
The location of the static nodes needs to be known to find the mobile device's location; thus, the system needs to be calibrated by entering the exact location of the static component to find the location of the mobile devices.
In this thesis, I discuss the possibility of self-calibrating a lateration-based localization system by taking the relative measurements of a mobile device to the static nodes at random times without initially knowing either the mobile device's location or the locations of the static nodes.
After modeling the system mathematically, I show that it is possible to detect the positions of the static nodes by deriving a nonlinear model of the geometric configuration that can be solved after making several assumptions by using numerical and optimization approaches, such as the trial-and-error or the Levenberg-Marquardt algorithm, it is possible to detect the positions of the static nodes; however, there are some limitations to this method as it requires a certain number of static nodes and a minimum number of recorded measurements to be able to find a unique solution to the system; these constraints differ depending on the nature of the system and the lateration technique used to record the measurements
The influence of tire wear particles (microplastic) on food security With a focus on agriculturally relevant plant species (Avena sativa L., Brassica napus L. & Zea mays L.) and soil organisms (Aporrectodea caliginosa & Eisenia andrei)
No full textDevelopment and implementation of environmental assessment concepts must gain stronger positions in policy making. This thesis focuses on the influences of currently, widely unregulated microplastic tire wear particle emissions on food security. An overview of global differences in microplastic waste treatments is given. Changes in behavior, law-making and technical innovations are argued to be equally needed to stop the ongoing pollution to prevent negative impacts on ecosystem services as the foundations for food security. In an experimental set-up, three particle size ranges (<125,125-250, 250-500 μm) in three treatment concentrations (0.01, 0.1, 1 %) with a negative control were applied to determine the influence of microplastic tire wear on three arable crop species and two earthworm species. Evenly, for all administrations, no significant effects could be observed on the organisms’ height, biomass, RSR, or body tissue. Nevertheless,
the results should not be interpreted as an all-clear signal, as the experiments observed only a few of the vast amounts of microplastic sinks. More data is needed as the EU Commission's recent “call to action” emphasizes. Determination of species resilience factors and traits shall be foci of future investigations to find cofactors for solution strategies. A more precise definition of microplastic and its
additives classifications will certainly aid the consensus on priorities in research and consumers' clarity about biodegradability
Significance of gut microbiota in prognosis of cancer therapy-induced rectal mucositis and treatment outcome
No full textColorectal cancer is a common type of cancer. Chemotherapy is an important method to treat cancer. 5-fluorouracil (5-FU) is a commonly used drug in chemotherapy regimens. 5-FU not only inhibited cancer cell division but also accelerated the apoptosis of intestinal epithelial cells. lead to colorectal mucositis. Some patients will develop severe mucositis, making subsequent treatment difficult and even life-threatening. The role of gut microbiota in the process of 5-FU-induced colorectal mucositis, and the regulation of gut microbiota through dietary regimens to reduce the possibility of colorectal mucositis deterioration are the research directions of this thesis. This thesis uses PubMed, NCBI and textbooks as the main reference sources, and some information comes from trusted websites. Through review and integration of research, it was concluded that gut microbiota played a non-negligible role in 5-FU-induced colorectal mucositis. Probiotics help maintain the stability of the intestinal mucosal barrier. The main cause of colorectal mucositis is that 5-FU suppresses the immune system and disrupts the immune system. Under the influence of 5-FU, intestinal flora dysbiosis occurs, and the intestinal mucosal barrier function is negatively affected. This leads to the worsening of colorectal mucositis. It can be inferred from research that a reasonable dietary regimen can reduce the possibility of exacerbation of colorectal mucositis. Furthermore, the digestive tract should be viewed as a whole. The role of the stomach and small intestine in the process of 5-FU-induced colorectal mucositis still needs further study. The research of gut microbes in this thesis focuses on Bifidobacterium and Lactobacillus. Pathogenic/opportunistic pathogens and other probiotics are understudied. More in-depth studies are still needed on the role of gut microbes in the process of 5-FU-induced colorectal mucositi

Effects of Simulated Drought on Microbial Activity in Biologically and Conventionally managed Soils
No full textIncreasing droughts and intensified agricultural management cause stress and disturbance on agricultural soil, but their effects on soil microbial activity are not fully known yet. This thesis studied the effects of induced short-term drought in two contrasting agricultural management systems, namely biodynamic (BioDyn) and conventional (ConMin), on microbial activity. The soil samples taken from the DOK long-term trial were analysed using MicroResp™, fluorometric enzyme assays and disease suppression bioassays. Soil basal- and multiple substrate-induced respiration (MSIR), microbial functional diversity, extracellular enzymatic activity (EEA) and soil suppressiveness against Pythium ultimum (Pu) were evaluated as indicators for microbial activity. Drought increased basal respiration but had no effects on other parameters. Conventional farming decreased EEA involved in carbon (C)- and nitrogen (N)-cycling, while it increased phosphorus (P)-cycling. No significant effects on the interaction between farming system and drought were found. The results indicate that organic farming has, to some extent, positive effects on microbial activity while drought does not decrease activity but induces stress in microorganisms
Implementierung und iterative Entwicklung eines Konzepts für eine Wissensduell-Applikation im Kontext von Serious Games
No full textThis bachelor thesis accompanies and documents the implementation and first step in the iterative development of a concept for a knowledge duel application. The application’s goal is to exploit a player’s playfulness and competitiveness, in order to learn new information and reinforce previously acquired knowledge. The concept was developed in cooperation with the Bäumer, Afonso, Meissner GmbH. Because of its goal, the concept and its implementation are analyzed in the context of serious games. To achieve this, the thesis first examines the meaning of the serious games term and what their most significant attributes are. It also explores some state of the art systems and concepts of all the implementation’s related fields. After extensive documentation of the concept and its implementation in the form of the web application called sw¨up, a formative evaluation using the results of several semi-structured interviews takes place. Following that, the
thesis further explores possible improvements and new features for later iterations of the application. The evaluation shows that sw¨up happens to be a very intuitive, performant and both optically and structurally well designed application. Additionally several problem fixes and improvements were found while evaluating the interviews’ results. While it is shown that sw¨up shares many similarities with a serious game, it can not be proven with the acquired results that sw¨up can effectively cause a learning effect and thus be considered a serious game. This remains to be determined by further, more in-depth tests and evaluations
Effect of the combination of fermentation and enzymatic hydrolysis on the functional properties, sensory profile and main allergens of pea protein isolates
No full textWith a rising demand of ecological, healthy, safe and appealing protein alternatives, legumes, such as peas (Pisum sativum), become more and more important in the food industry as they can fulfil these demands to provide plant-based protein alternatives. To be successful on the food market, it is important to develop ingredients with no or low allergic potential, good functional properties, and appealing sensory characteristics. Treating pea protein isolates (PPI) with enzymatic hydrolysis (EH) and lactic acid fermentation (F) can result in high-quality protein alternatives.
In this study, PPI was hydrolysed for 120 min with three different enzymes (papain, Esperase®, trypsin) in combination with a 24 h lactic acid fermentation (L. plantarum). The treatments were performed either with enzymatic hydrolysis first (HF) or with fermentation first (FH). The molecular weight distribution and the degree of hydrolysis (DH) were analysed to determine the treatment’s effect on potential pea allergens. The protein solubility (PS), emulsifying capacity (EC), and foaming properties were investigated. The sensory profile was evaluated by 11 panellists, who ranked the samples by the attributes “plant-like” and “bitter”.
The FH combination samples with Esperase® and trypsin did not apparently show potential allergen fractions. The highest degree of hydrolysis of combined treatments was obtained by the HF_Esperase® sample (10.76 %), whereas FH_papain showed the lowest (3.92 %). The protein solubility was improved by all samples that were hydrolysed. At pH 7.0, HF_Esperase® increased the protein solubility up to 67.28 % and the only fermented PPI showed the lowest (10.72 %). At pH 4.5, FH_Esperase® showed the highest protein solubility (66.55 %) and the fermented PPI the lowest (5.72 %).
The highest emulsifying capacity was reached by the untreated PPI (730 mL/g), whereas the lowest was reached by HF_Esperase®. The highest foaming capacity was shown by FH_trypsin (2575 %) and the lowest by the fermented PPI (808 %). The most stable foam was built by the untreated PPI (77 %); any of the samples treated with Esperase® and trypsin were not able to form a stable foam.
The most “bitter” sample was FH_Esperase® and the least was FH_papain. The untreated PPI was rated the most “plant like”, whereas FH_trypsin was rated the least “plant like”.
Overall, the combination of EH and F changed the molecular weight distribution of the PPI, apparently degrading the potential pea allergens. The combinations of the treatments showed good functional properties and reduced pea characteristic flavour. The chosen enzyme as well as treatment conditions and sequence should be considered to develop high quality PPI ingredients
„Eine Analyse der betrieblichen Gesundheitsförderung in einem mittelständischen Unternehmen mit Handlungsempfehlungen für ein betriebliches Gesundheitsmanagement“
No full textDie vorliegende Arbeit analysiert die gesundheitsfördernden Maßnahmen des Chemieunternehmens Kao Chemicals GmbH und prüft, die Notwendigkeit ein betriebliches Gesundheitsmanagement einzuführen. Das Thema Gesundheit im Betrieb gewinnt auf Grund des demografischen Wandels, des Fachkräftemangels und den steigenden Gesundheitskosten für die Gesellschaft zunehmend an Bedeutung. Um die Mitarbeiter in einem Unternehmen gesund und dadurch leistungsfähig zu halten, bieten Betriebe den Mitarbeitern verschiedene Gesundheitsförderungsprogramme an. Oftmals werden diese mit dem betrieblichen Gesundheitsmanagement gleichgesetzt. Dabei handelt es sich bei einem betrieblichen Gesundheitsmanagement um einen geplanten strukturierten Prozess, bei dem zu erreichende Ziele definiert werden. Durch die Planung von gezielten Maßnahmen, die Anpassung an Zielgruppen und die stetige Evaluation, kann dieser Prozess an die sich möglichen veränderten Gegebenheiten in Unternehmen angepasst werden. Dies ermöglicht dem Arbeitgeber seine Mitarbeiter zu motivieren und in ihrer Gesundheit zu fördern. Dadurch wird das Unternehmen leistungsfähiger und sichert sich einen Vorteil gegenüber der Konkurrenz. In einem betrieblichen Gesundheitsmanagement werden gesetzlich vorgeschriebene Aspekte des Arbeits- und Gesundheitsschutzes sowie dem betrieblichen Eingliederungsmanagement vereint.
Im Rahmen dieser Arbeit werden drei Forschungsfragen aufgestellt und im Verlauf beantwortet. Zu Beginn wird der Frage nachgegangen, ob die angebotenen Maßnahmen zur Gesundheitsförderung ausreichend und zielführend sind. Des Weiteren wird hinterfragt, ob das Unternehmen ein betriebliches Gesundheitsmanagement benötigt und im Anschluss erörtert, wie ein betriebliches Gesundheitsmanagement im Unternehmen umgesetzt werden könnte. Dazu werden am Ende Handlungsempfehlungen für die Kao Chemicals GmbH verfasst.
Zur Beantwortung der Forschungsfragen wurde die Methode der Sekundärforschung verwendet. Dazu wurden bestehende Statistiken und Analysen der Kao Chemicals GmbH zusammengetragen, ausgewertet und mit bestehender Fachliteratur abgeglichen. Zum besseren Verständnis der Umsetzung eines betrieblichen Gesundheitsmanagements werden zwei Beispiel aus der Fachliteratur beschrieben. Die Auswertung der Daten der Kao Chemicals GmbH ergaben, dass durch die Anpassung der Maßnahmen an definierte Zielgruppen und die klare Kommunikation von Zielen der Nutzen für die Mitarbeiter verdeutlicht und dadurch die Teilnehmerquote verbessert werden könnte. Auf dieser Basis konnten spezifische Handlungsempfehlungen zur Implementierung und Umsetzung eines betrieblichen Gesundheitsmanagements verfasst werden
