Investigating the primary stability of the transversal support tibial plateau concept to retain both cruciate ligaments during total knee arthroplasty
Purpose: The important roles of the anterior cruciate ligament regarding knee stability, physiologic kinematics, and proprioception are unquestioned. Thus, various efforts have been made to retain the ACL during total knee arthroplasty (TKA). Neither of the existing solutions to this problem, i.e. bicruciate retaining prostheses and implantation of two unicondylar prostheses, has been successful because of concept-specific problems as well as general difficulties with implant fixation. The new transversal support tibial plateau concept is a prosthesis of two individual joint surfaces reinforced beneath the articular line by joint surface supports and buttressed by a single transversal support. This configuration, which enables retention of both cruciate ligaments, should provide good bone fixation and ensure long-term alignment of the individual joint surfaces.
Methods: In the current study, four prototypes based on this novel concept were developed and the resulting primary stability was analyzed using adapted load testing. The test set-up, with the model-loading of specially prepared Sawbones® and a sinusoidal oscillating load transmission with 25 000 cycles over 10 increasing load levels, achieved subsidence, which enabled comparison of the four different model variants regarding primary stability in view of bone anchoring.
Results: The model variant (TSmobile) that allowed transverse glide of the joint surface supports along the transversal support revealed the largest subsidence.
Conclusions: A rigid attachment of the joint surface supports of the transversal support tibial plateau thus appears to offer increased primary stability regarding bone anchoring
Developing a methodical approach for the systematic identification of innovative technological applications - based on mixed reality in manual order picking
The need to be economically successful is the key driver for companies to be innovative and implement new technologies with increasing efficiency and effectiveness (Klein & Stumpp, 2007). Uncertainty about whether to use new technologies and missing knowledge about their advantages lead to staggering and withholding from fast diffusion of innovations (Moore, 1999), (Rogers, 2003). Focusing on the industry of logistics and the technology Mixed Reality, this research project developed a methodical approach for evaluating the fitness of an innovative technology and a specific process of application.
A mixed methods approach was derived, based on interviews and experiments. The main methodologies used, were semi-structured interviews with decision makers in logistics companies to elaborate triggering criteria in the investment process and laboratory experiments for the evaluation of competing technologies. These methods were framed by an initial field experiment and feedback interviews after the analysis for the validation of the approach.
The research proved the competitively viable applicability of Mixed Reality and its specific strengths and weaknesses in manual order picking. This set the foundation for possible further development and implementation of the technology. The developed methodological approach proved to be a valid and reliable assessment of the intersection between a technology and specified process of application. This could greatly enhance the speed of implementing new innovations and gaining competitive advantages for companies.
The research provides four contributions to the present knowledge. The main and major contribution is based in the field of innovations management. A new framework is derived to evaluate the suitability of an innovative technology for an existing process. It offers an assessment of the strengths and weaknesses of technologies within the area of application and a conclusive recommendation for or against further implementation.
The framework consists of finding the determining criteria for a technological and economic useful implementation and the evaluation of existing and pending technologies within the found criteria.
The minor contributions to the present knowledge are, in their corresponding areas of research:
Logistics, Order Picking: Current technologies for manual order picking are evaluated according to procedural and entrepreneurial requirements of the industry. The results of the evaluation offer a clear advice of what technology to use at the moment for a specific company or process. Furthermore, the applied methodological approach can be reused if determining criteria for the evaluation change or new technologies emerge.
Mixed Reality: The process of order picking is identified and evaluated positively as an appropriate field for the serial application of Mixed Reality and as a market beyond prototypal implementation. The results of the research approve the fitness from both, technological and economic criteria.
Methodological Approach: Qualitative and quantitative methodologies, namely interviews and experiments, were combined in a mixed-methods-approach. The approach incorporates four steps of alternating qualitative and quantitative methodologies. This offers unprecedented validity and reliability for the results of the methodological approach
Wie wählen Fußgänger ihren nächsten Schritt? Implementierung einer Entscheidungsheuristik in crowd:it
Aktuelle Tools zur Simulation von Personenströmen haben Probleme bei der Berechnung von Gegenstrom-Szenarien. Dabei kommt es häufig zur Bildung unlösbarer Staus, welche in der Realität so nicht entstehen würden. Das Simulationstool crowd:it der Firma accu:rate verwendet aktuell das Optimal Steps Model, bei dem ebenfalls unlösbare Staus entstehen können. Diese Arbeit untersucht, ob das Behavioural Heuristics Model von Michael Seitz geeignet ist, um solche Blockaden zu vermeiden. Das im Behavioural Heuristics Model enthaltene Following-Verhalten scheint hierfür ein plausibler Ansatz zu sein, darum wird das Modell in crowd:it implementiert. Durch einen Vergleich der Ergebnisse mit den Beobachtungen von Herrn Seitz wird eine korrekte Implementierung bestätigt. Es zeigt sich, dass das Behavioural Heuristics Model in Gegenstrom-Szenarien sogar mehr Blockaden erzeugt als das Optimal Steps Model. Eine Reihe von Simulationsexperimenten mit den Basis-Ansätzen, Kombinationen und Variationen davon liefern das gleiche Ergebnis. Außerdem wurde der Einfluss von „Durchdrücken“ untersucht, wodurch sich bei beiden Modellen deutlich seltener unlösbare Staus bilden. Bei der Verwendung des Optimal Steps Models, bei welchem „Durchdrücken“ erlaubt war, bilden sich am seltensten unlösbare Staus.Latest crowd simulation tools show issues simulating counterflow scenarios. Pedestrian simulations end up very often in the formation of unsolvable jams, which would not occur in reality like this. The simulation tool crowd:it from accu:rate is currently using the Optimal Steps Model, with which unsolvable jams occur too. This thesis examines, if the implementation of the Behavioural Heuristics Model from Michael Seitz would lead to a reduced formation of jams in counterflow scenarios. The so called „following behaviour“, which is part of the Behavioural Heuristics Model, provides an opportunity to improve the model. Therefore the Behavioural Heuristics Model was implemented in crowd:it and analysed in the course of this thesis. In a comparison of the results in this thesis and the findings from Michael Seitz the correctness of the implementation could be approved. It turned out, that the Behavioural Heuristics Model produces even more jams in counterflow scenarios than the Optimal Steps Model. A series of simulation experiments using the basic models, combinations, and variations of these, came to consistent results. The influence of squeezing through a crowd was also tested and showed as a result that significantly less jams were build up. The Optimal Steps Model combined with squeezing led to the best results in counterflow scenarios
Iterative matrix algorithm for high precision temperature and force decoupling in multiparameter FBG sensing
A new iterative matrix algorithm has been applied to improve the precision of temperature and force decoupling in multi-parameter FBG sensing. For the first time, this evaluation technique allows the integration of nonlinearities in the sensor’s temperature characteristic and the temperature dependence of the sensor’s force sensitivity. Applied to a sensor cable consisting of two FBGs in fibers with 80 μm and 125 μm cladding diameter installed in a 7 m-long coiled PEEK capillary, this technique significantly reduced the uncertainties in friction-compensated temperature measurements. In the presence of high friction-induced forces of up to 1.6 N the uncertainties in temperature evaluation were reduced from several degrees Celsius if using a standard linear matrix approach to less than 0.5°C if using the iterative matrix approach in an extended temperature range between −35°C and 125°C
An empirical investigation of the perception of target group-oriented crisis communication at the Hochschule München University of Applied Sciences during the Corona crisis
Krisenkommunikation ist eine wichtige Aufgabe der internen und externen Kommunikation von Hochschulen. In der vorliegenden Bachelorarbeit wurde am Beispiel der Corona-Krise mithilfe einer qualitativen Befragung von Mitarbeitenden und einer quantitativen Befragung von Studierenden untersucht, wie diese beiden Akteursgruppen die Krisenkommunikation an der Hochschule München wahrgenommen haben.
Zur Beantwortung der Forschungsfragen wurde die qualitative Befragung in Form von halbstandardisierten Leitfadeninterviews durchgeführt, die Auswertung erfolgte softwaregestützt in Form einer qualitativen Inhaltsanalyse. Mit den gewonnenen Erkenntnissen aus den Interviews über die interne Wahrnehmung wurde ein Online-Fragebogen mit geschlossenem Antwortformat erstellt, um Studierende hinsichtlich der Wahrnehmung der externen Krisenkommunikation an der Hochschule München zu befragen. Durch die Ergebnisse der empirischen Untersuchung konnten Rückschlüsse auf die Kommunikationsstrategie der Hochschulkommunikation an der Hochschule München gezogen werden. Abschließend wurden aus den beiden Befragungen Empfehlungen für die zukünftige Krisenkommunikation der Hochschulkommunikation abgeleitet.
Die Ergebnisse zeigen die Wichtigkeit von zielgruppengerechter Krisenkommunikation und aktueller Informationsbereitstellung über geeignete Kanäle in Krisen-zeiten auf und beleuchten die Einstellung zur Nutzung digitaler Instrumente. Außerdem wurden unter anderem die Stärken und Schwächen der bisherigen Krisenkommunikation an der Hochschule München in der Corona-Krise und die Auswirkungen auf die interne und externe Stimmung identifiziert.Crisis communication is an important task of universities' internal and external communication. This bachelor thesis investigates how members of two different groups – university employees and students – perceived the crisis communication during the Corona crisis at the Hochschule München University of Applied Sciences.
In a first step, semi‐standardized interviews with university employees were carried out to examine how members of this recipient group perceived the internal crisis communication of the university. Data analysis was software-supported and conducted using qualitative content analysis. Based on the findings from the interviews, closed-ended items were developed and compiled as an online questionnaire. In a second step, the questionnaire was used to examine how university students perceived the external crisis communication at the Hochschule München University of Applied Sciences during the Corona crisis. The results of the empirical study allowed conclusions to be drawn about the communication strategy of the Public Relations Department at the Hochschule München University of Applied Sciences. Finally, recommendations for possible adjustments in future crisis communication strategies of the Public Relations Department were derived from the two surveys.
Findings from the two surveys revealed the importance of target group-oriented crisis communication and up-to-date information provision through suitable channels in times of crisis and also highlights the attitude towards digital instruments. In addition, the strengths and weaknesses of the previous crisis communication at the Hochschule München University of Applied Sciences during the Corona crisis and the effects on the internal and external atmosphere were identified
