O IMPACTO DA QUALIDADE DE ENSINO NA CONSTRUÇÃO DO RELACIONAMENTO ENTRE ALUNO E MARCA DA UNIVERSIDADE

O objetivo deste estudo é avaliar a influência da qualidade ensino no relacionamento dos alunos com a marca da IES. Assim, têm-se como hipótese de pesquisa que o relacionamento aluno/aluno e professor/aluno, a estrutura oferecida pela IES, a qualificação do docente e os métodos de ensino, sendo fatores da qualidade de ensino, influenciam positivamente o relacionamento do aluno com a marca da IES. Para atendimento do objetivo propõe-se uma nova escala para mensurar a qualidade de ensino e utiliza-se uma escala de qualidade do relacionamento já validada no contexto brasileiro. O estudo desenvolveu-se em três etapas: (1) pesquisa bibliográfica e entrevista em profundidade para geração dos itens da escala de qualidade de ensino, (2) levantamento para purificação dos itens da escala de qualidade de ensino e (3) novo levantamento para validação da escala de qualidade de ensino e teste da hipótese através de modelagem de equações estruturais. Os resultados apontam que a influência da qualidade de ensino no relacionamento dos alunos com a marca da IES alcança 75,9%. Comprovou-se ainda que alunos não bolsistas, homens e aqueles que estão no início do curso são mais sensíveis a relação

An In-Switch Architecture for Low-Latency Microservices

In recent time, there is has been a movement away from standard monolithic architecture in cloud and web services towards what is known as a microservice architecture. Microservice architecture decomposes the previous monolithic architecture into multiple independent services called "microservices". Examples of applications that use a microservice architecture include Netflix and Amazon. These applications typically send large numbers of microservice requests, which go through the OSI network layers to establish a client server connection. This trend towards microservices has developed interest by other researchers to make improvements in this field, due to the growing reliance importance on such architectures by consumers. There have been studies regarding the security of these microservices, performance analysis of various applications, and the use of these microservice applications in cloud technology. Any improvements in the speed, security, or organization of such network architecture would be very beneficial of these popular API's, and their user base. This project's objective is to investigate the potential of moving some of the processing that is done for these microservices within a network switch, and as a result the performance at the application level, by alleviating network communication. We formulate a high-level design for an in-switch architecture for low-latency microservice leveraging existing programmable-switches support. We investigate the implementation of NetCache as a microservice in our model and predict a significant latency reduction and subsequent performance increase

Quantitative monitoring of laser-treated engineered skin using optical coherence tomography

Nowadays, laser therapy is a common method for treating various dermatological troubles such as acne and wrinkles because of its efficient and immediate skin enhancement. Although laser treatment has become a routine procedure in medical and cosmetic fields, the prevention of side-effects, such as hyperpigmentation, redness and burning, still remains a critical issue that needs to be addressed. In order to reduce the side-effects while attaining efficient therapeutic outcomes, it is essential to understand the light-skin interaction through evaluation of physiological changes before and after laser therapy. In this study, we introduce a quantitative tissue monitoring method based on optical coherence tomography (OCT) for the evaluation of tissue regeneration after laser irradiation. To create a skin injury model, we applied a fractional CO2 laser on a customized engineered skin model, which is analogous to human skin in terms of its basic biological function and morphology. The irradiated region in the skin was then imaged by a high-speed OCT system, and its morphologic changes were analyzed by automatic segmentation software. Volumetric OCT images in the laser treated area clearly visualized the wound healing progress at different time points and provided comprehensive information which cannot be acquired through conventional monitoring methods. The results showed that the laser wound in engineered skins was mostly recovered from within 1~2 days with a fast recovery time in the vertical direction. However, the entire recovery period varied widely depending on laser doses and skin type. Our results also indicated that OCT-guided laser therapy would be a very promising protocol for optimizing laser treatment for skin therapy.clos

Health Insurance and Disclosure of Same-Sex Sexual Behaviors Among Gay and Bisexual Men in Same-Sex Relationships

Purpose: Gay and bisexual men (GBM) have poorer health outcomes than the general population. Improved health outcomes will require that GBM have access to healthcare and that healthcare providers are aware of their sexual behaviors. This study sought to examine factors associated with having health insurance and disclosure of same-sex sexual behaviors to primary care providers (PCPs) among GBM in primary same-sex relationships. Methods: We conducted an online survey of a national sample of 722 men in same-sex couples living in the United States. Logistic regression and multinomial regression models were conducted to assess whether characteristic differences existed between men who did and did not have health insurance, and between men who did and did not report that their PCP knew about their same-sex sexual activity. Results: Our national sample of same-sex partnered men identified themselves predominantly as gay and white, and most reported having an income and health insurance. Having health insurance and disclosing sexual behavior to PCPs was associated with increasing age, higher education, and higher income levels. Insurance was less prevalent among nonwhite participants and those living in the south and midwest United States. Disclosure of sexual behavior was more common in urban respondents and in the western United States. In 25% of couples, one partner was insured, while the other was not. Conclusions: Having health insurance and disclosing one's sexual behavior to PCPs was suboptimal overall and occurred in patterns likely to exacerbate health disparities among those GBM already more heavily burdened with poorer health outcomes. These factors need to be considered by PCPs and health policymakers to improve the health of GBM. Patient- and provider-targeted interventions could also improve the health outcomes of GBM.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/140156/1/lgbt.2013.0050.pd

Funktioneller und struktureller Nachweis einer ipsilateralen Verbindung zwischen dem dorsalen prämotorischen und dem primär motorischen Kortex

Der primär motorische Kortex (M1) steuert die Bewegungen der kontralateralen Körperseite. Der dorsale prämotorische Kortex (PMd) spielt eine wichtige Rolle bei der Abstimmung von Bewegungen auf äußere, vor allem somatosensorische Einflüsse sowie deren Integration in Bewegungsabläufe. Aus Studien an Primaten ist bekannt, dass zwischen dem ipsilateralen PMd und der Handregion des M1 direkte Verbindungen bestehen. Wie genau der PMd Einfluss auf den M1 im menschlichen Gehirn ausübt, wurde im Rahmen dieser Arbeit mit Hilfe der transkraniellen Magnetstimulation (TMS) nicht-invasiv untersucht. Hierfür kamen speziell entwickelte Präzisionsspulen (MAG & More) zur Anwendung, welche die Stimulation der dicht benachbarten Regionen erst möglich machten. Ein neuartiges Doppelpulsparadigma mit kurzen Latenzzeiten wurde entwickelt, um eine Interaktion mit den deszendierenden Wellen zu erreichen und so Auskunft über die zeitliche Diskrimination der Verbindung zu erhalten. Es wurden verschiedene Faktoren zur Änderung der kortikalen Erregbarkeit sowie ihr Einfluss auf die Verbindung der Areale untersucht: die Vorinnervation der Zielmuskeln in Experiment 2 sowie die Bearbeitung einer Wahl-Reaktionszeit-Aufgabe in Experiment 3. Durch die Diffusions-Tensor-Bildgebung (DTI) wurde die Mikrostruktur der subkortikalen weißen Substanz im Bereich des PMd dargestellt. Als Maß dafür diente die fraktionelle Anisotropie (FA). Im Rahmen der Doppelpulsstimulation wurde zunächst ein überschwelliger Puls über dem M1 appliziert, gefolgt von einer unterschwelligen Stimulation des PMd. In Experiment 1 erfolgte die Stimulation zunächst unter Ruhebedingungen. Die Pulse wurden in Interstimulusintervallen von 0,8 ms bis 2,0 ms in Schritten von 0,4 ms appliziert. Des Weiteren wurde in Experiment 2 unter sonst identischen Bedingungen der Einfluss einer willkürlichen Vorinnervation des Musculus interosseus dorsalis I untersucht. Im letzten Teilexperiment wurde 75, 100 und 125 ms vor der TMS- Applikation eine Wahl-Reaktionszeit-Aufgabe gestellt. Die Probanden wurden durch eine visuelle Anleitung dazu aufgefordert eine Reaktion mit der linken oder rechten Hand auszuführen. Die ISI betrugen 0,8, 1,2 und 1,6 ms. Die durch DTI erhobenen FA-Werte wurden schließlich mit den TMS-Daten korreliert. Durch die Doppelpulsstimulation unter Ruhebedingungen konnte eine signifikante Bahnung bei einem ISI von 1,2 ms festgestellt werden. Eine Vorspannung des Zielmuskels führte dazu, dass keine MEP mehr abzuleiten waren und bewirkte somit eine Modulation der Verbindung. Durch die Wahl-Reaktionszeit-Aufgabe konnte eine aufgabenspezifische Aktivierung bei einem ISI von 1,2 ms, einem SOA von 125 ms und einer Reaktion mit der rechten Hand erzielt werden. Mittels DTI gelang es das strukturelle Korrelat der Verbindung in der weißen Substanz unterhalb des PMd darzustellen (MNI-Koordinaten x, y, z = -15, -10, 55). Die Analyse ergab einen positiven linearen Zusammenhang zwischen der funktionellen Ausprägung der Verbindung und der Struktur der subkortikalen weißen Substanz. Die identifizierte Bahnung in Ruhe tritt nach einer kurzen Latenzzeit auf. Die Periodik dieser Bahnung entspricht dem Auftreten von I-Wellen und spricht dafür, dass die Signale vom PMd die Aktivität des M1 über intrakortikale Regelkreise der I-Wellen beeinflussen können. Diese Studie kann so eine direkte, ipsilaterale Verbindung bestätigen und liefert Hinweise dafür, dass diese mit der Entstehung von I-Wellen assoziiert ist. Die kurze Latenzzeit der Bahnung weist auf das Vorliegen einer schnell leitenden, monosynaptischen Verbindung hin. Weiterhin kann festgestellt werden, dass die I-Wellen im Ruhezustand einen größeren Einfluss auf den M1 haben als unter Vorinnervation. Die Bahnung durch die Wahl-Reaktionszeit-Aufgabe kann durch eine Veränderung der kortikalen Erregbarkeit erklärt werden und korreliert mit der Ausprägung der subkortikalen Bahnen im Bereich des PMd. Die Kontrollexperimente belegen, dass die Ergebnisse für den stimulierten Bereich spezifisch sind, und schließen eine reine Erregungsausbreitung oder Aufsummierung der Pulse aus. Mit dem verwendeten Doppelpulsparadigma, den Präzisionsspulen und DTI können in Zukunft weitere intrakortikale Bahnen funktionell und strukturell untersucht werden. Insbesondere kann deren Funktionszustand und Veränderung im Rahmen der Reorganisation nach einem Schlaganfall beurteilt und beeinflusst werden
