Orientador: João Antonio Pereira / Resumo: A indústria fonográfica com o advento dos equipamentos digitais de gravação sofreu grandes transformações nos últimos anos. A mudança mais marcante é a migração dos músicos que antes trabalhavam com grandes gravadoras e hoje trabalham de forma independente, com estúdios construídos ou adaptados em suas residências, os chamados home studios. Seja em um grande estúdio profissional de gravação, ou em um home studio, o estudo da acústica do local é imprescindível para se obter boa qualidade nas gravações. Uma das áreas aplicadas da acústica é a avaliação e desenvolvimento de ambientes utilizados para gravações de áudio. Essa área contempla diversas avaliações de grande valia, quando se trata da garantia da qualidade acústica das salas em um home studio. Reverberações, isolamento sonoro, entre outras variáveis de projeto definem parâmetros acústicos do ambiente. A obtenção destes parâmetros e adaptações do local para diferentes usos, entre outras características utilizadas para avaliação da qualidade sonora dos ambientes, podem ser dadas através do estudo e avaliação do modelo acústico do estúdio, visto que esses parâmetros estão diretamente relacionados com os materiais construtivos, dimensões e arquitetura do ambiente. Este trabalho teve como objetivo o estudo do efeito desses parâmetros na acústica dos ambientes e a criação de modelos numéricos representativos de predição acústica, a partir da análise e avaliação em dois estúdios diferentes. Assim, provendo embasamento teórico-...

The most remarcable change is the migration of musicians that used to work with great record labels before and nowadays work in an independent way, with studios constructed in their residences, the so called home studios. Whether in a large professional recording studio, or at an home studio, the study of local acoustics is imprescindible for obtaining good recording quality. One of the applied areas of acoustics is the valuation and development of enviroments used for audio recordings. This front of study includes many evaluations of great worth when it comes to guaranteeing the acoustic quality in a home studio. Reverberations, sound insulation, between other variables de ne the acoustic quality of the enviroment. The obtention of these parameters and adptations of the room for di erent kind of usage, along with other characteristics utilized for the valuation of acoustic quality of enviroments, may be given through study and valuation of an acoustic model of the studio, since these parameters are directly related to the building materials, dimensions and architecture of the environment. The objective of this work was to study the e ect of these parameters on the acoustics of the environments and the creation of representative numerical models of acoustic prediction, from the analysis and evaluation in two di erent studios, so that it is possible ...

Design constraints is the first topic new interaction designers learn about intheir studies. These are supposed to be the properties of a design that limitsuser’s actions. This thesis aims to explore these constraints in depth tounderstand if there is more to learn about them when placed in a new setting,such as games. This knowledge could then be used to create better player oruser experience. To discover this, a detailed study of two escape rooms wasconducted and analyzed.The investigation showed that there is more to design constraints thanpreviously mentioned by theorists, especially when context changes, and thatdesign constraints should instead be interaction opportunities. Instead ofonly seeing constraints as limiting actions, they should become the clues forpossible interactions.

In the model room task, children watch as a miniature toy is hidden somewhere in a scale model of a room and are asked to find the larger version of the toy in the corresponding place in the actual room. Previous work has shown that children under age three often perform very poorly on this task. One prominent theory for their failure is that they lack the ability to understand the model as both a physical object and as a symbolic representation of the larger room. An alternative hypothesis is that they need to overcome weak, competing representations of where the object was on a previous trial, and where it is in the present trial, in order to succeed in their search. Children aged 33-39 months were tested on measures of inhibitory control, cognitive flexibility, recognition memory, and receptive vocabulary, as well as the model room task. Results showed that performance on the model room task was not predicted by measures of inhibitory control, cognitive flexibility or vocabulary, but was predicted by performance on the Delayed Recognition Span Test (DRST), a measure of recognition memory. These findings lend support to the theory of competing representations. Given the predictive nature of the recognition memory task and the task’s sensitivity to lesions in the hippocampus, implications for the development of the hippocampus and its role in success on the model room task are discussed.

The aim of this thesis was to examine the contribution of nurses to interprofessional collaboration (IPC) in the operating room (OR) guided by the Interprofessional Education Collaborative Patient Care Practice (IECPCP) framework. First, a secondary analysis of interviews with 19 registered nurses was conducted. Twenty emergent themes were identified. The most prevalent of the four dimensions (internalization; shared goals and vision; governance; and formalization) consisted of the internalization dimension relating to human interaction and sense of belonging within the interprofessional team. A scoping review then identified 20 studies evaluating four interventions (briefings, checklists, team training, and debriefings) used to improve IPC in the OR. Despite weak study designs, these interventions showed improvements in communication, teamwork, and safety outcomes. OR nurses contribute mainly through interactional processes and they require organizational support to foster their efforts in IPC. Nurse are involved in all IPC interventions and their contribution is important to support IPC in the OR.

In this paper, I study how a new law (the Convention on the Rights of the Child) is implemented in Lomma municipality. I investigate how the new law has been implemented in the municipality and how my informants experience their room of maneuver to carry out the changes required to implement the law in their business. Methodological tools used are interviews with four informants. The analysis is guided by Lundquist's theory of implementation as well as Lipsky's theory of room of maneuver.  The study results in that the implementation of the law has mainly taken place through the appointment of a working group with responsibility for the implementation. After that nothing more significant has happened in the implementation process. The informants have a room for maneuver, but are strongly influenced by management and the policy framework. Therefore, it will be difficult for the informants to fully implement the law in the business. It is not possible to draw generalizing conclusions based on the results because it is a specific case that is being analyzed, but similar studies with other municipalities in focus are examples of future research areas.

The progress of digital technologies within the television industry has led to moreadvanced equipment, both for private and professional use. One specific area wherethis development has been noticed is in control rooms used to conduct live or tapedtelevision broadcasts. To conduct "traditional" live broadcasted programs, a variety ofoperators in the control room works and each operator is responsible for one specificequipment, such as a sound engineers and vision engineer.The digitization of technical equipment has also meant that all equipment used duringa newscast can be controlled from other devices, for example an external computer.This concept is known as centralization. The centralization has made possible thatonly one or two operators can be in charge of conducting an entire broadcast. The aimof this investigation has been to investigate how the production has been affected bycentralization, not only from a technical point of view but also how all those involvedto create a newscast has been affected.The apparent result has been that the amount of staff in the control room has beenreduced and this has led to further consequences for the remaining staff in production.The centralization has resulted in a less costly production for the production companyin the long run, because of the decreasing in staff. It has also resulted in additionalwork task for all staff involved in creating and broadcasting the news.The extended technical task for the operators in a centralized control room has meantthat the priority of focusing on the visual parts of the broadcast have decreased andtherefore, the visual aspects have been neglected. This factor was confirmed both bythe television viewers and editorial staff during different focus groups.Wider technical knowledge as well as greater dedication towards the overallresponsibility to carry out a broadcast is required from the operators operating in acentralized control room. The editorial staffs extending tasks in the form of keepingtrack of time and writing different headlines hasn’t directly affected the work tasks inthe sense of news gathering and filtering, only that additional responsibility has beenadded to them.The general mistake that occurs when the broadcasting is conducted in centralizedcontrol rooms, for all involving in the production, are preparation mistakes. It can forexample be incorrect programming from the operators or misspellings conducted bythe editorial staff, which in a traditional control rooms isn’t as common. However,centralized control rooms have reduced the mistakes during an actual broadcast,contrary to traditional control rooms. This is because the centralization andcomputerization generally has removed vast mistakes caused out the human factor.

Time Reversal (TR) is a technique that may be used to focus an acoustic signal at a particular point in space. While many variables contribute to the quality of TR focusing of sound in a particular room, the most important have been shown to be the number of sound sources, signal bandwidth and absorption properties of the medium [Ribay et al., J. Acoust. Soc. Am. 117(5), 2866-2872 (2005)]. However, the effect of room size on TR focusing has not been explored. Using the image source method algorithm proposed by Allen and Berkley [J. Allen and D. A. Berkley, J. Acoust. Soc. Am. 65(4), 943-950 (1979)], TR focusing was simulated in a variety of rooms with different absorption and volume properties. Experiments are also conducted in a couple rooms to verify the simulations. The maximum focal amplitude, the temporal focus quality, and the spatial focus clarity are defined and calculated for each simulation. The results are used to determine the effects of absorption and room volume on TR. Less absorption increases the amplitude of the focusing and spatial clarity while decreasing temporal quality. Dissimilarly, larger volumes decrease focal amplitude and spatial clarity while increasing temporal quality. This thesis also explores the placement of individual transducers within a room. It also compares the layout of several source transducers used for a reciprocal time reversal process. Maximum focal amplitude and spatial clarity are found to increase when the focus location is dual coplanar to the source location while temporal quality is found to decrease in comparison to the case when source and focal location share only one plane. Maximum focal amplitude is found to be at a minimum when the focus location is at the critical distance and increases closer and farther away from the source, while temporal quality steadily decreases and spatial clarity steadily increases farther from the source. The maximum focal amplitude and the temporal quality are not greatly affected by the type of array layout, but a circular array is ideal for maximizing spatial clarity.

As the pandemic of 2020 broke out there was an increase in the use of virtual meeting rooms as a platform for holding online lectures. The usefulness of being able to attend a lecture comfortably from home cannot be denied, however participants report feeling less engaged in lectures when studying remotely. By involving and engaging the participants in online lectures with the help of virtual Escape Rooms the participants can feel more engaged and perform better in their schoolwork. The result is a prototype that showcases how virtual Escape Rooms can be used for educational purposes. The prototype consists of a room that connects to a group of Escape Rooms. The participants can interact with each other and objects as well as communicate through text and voice chat. Further work is necessary for the application to be an effective tool for education. / När pandemin bröt ut 2020 ökade användningen av virtuella mötesrum som en plattform för onlineföreläsningar. Användbarheten av att bekvämt från hemmet kunna delta i föreläsningar kan inte förnekas, men undersökningar visar på att deltagare i virtuella mötesrum känner sig mindre engagerade i föreläsningar när de deltar på distans. Genom att involvera och engagera deltagarna i onlineföreläsningar med hjälp av virtuella Escape Rooms kan deltagarna känna sig mer engagerade och prestera bättre i sitt skolarbete. Resultatet är en prototyp som visar hur virtuella Escape Rooms kan användas i utbildningssyfte. Prototypen består av ett rum som är sammankopplat till en grupp Escape Rooms. Deltagarna kan interagera med varandra, samt interagera med objekt och kommunicera via textchatt och röstkommunikation. Ytterligare arbete behövs för att applikationen ska vara ett effektivt verktyg för utbildning.

This project represents the ever-changing methods surrounding Enhanced Recovery after Surgery and the protocols that compose it. The purpose of this study is to expand education of ERAS guidelines and improve patient outcomes through furthering staff education. Enhanced Recovery After Surgery has been a part of perioperative departments worldwide after being introduced in the 1990s by Northern European general surgeons and has been adapted and modified since its introduction (ERAS Society History, 2022). The preoperative and postoperative process is ever-changing and is difficult for staff to keep up with. Many staff members find it difficult to stay on top of the most recent protocols. From clerical staff to nurses to surgeons there is a breakdown in the process of ensuring patients receive the optimal benefits if ERAS. This presentation will serve to both educate viewers on the latest ERAS recommendations as well as help develop and define a workflow for ensuring staff members have the most updated guidelines available to streamline the process and provide the best recovery experience for patients.
