Johansson, Agnes, e Aleksandra Voronenko. "Creating a sense of normality : A quantitative study examining how a digital collaborative tool impacts students’ experiences in online synchronous group discussions". Thesis, Jönköping University, Tekniska Högskolan, 2021. http://urn.kb.se/resolve?urn=urn:nbn:se:hj:diva-53312.
Resumo:
Purpose – The unexpected yet drastic influence of the COVID-19 pandemic resulted in a rapid transition of education to be conducted in digital environments. Replacing face-to-face classrooms with synchronous online learning requires a number of appropriate adjustments which were heavily restricted by the urgency of this global change taking place. With theobserved issues of student participation and involvement in online learning, the purpose ofthis research was to investigate the potential that digital collaborative tools have and if theycan improve the quality of online group discussions among students aged 12 to 16 years old. Method – This study employs a quantitative data collection approach and makes use of the Community of Inquiry framework. A close-ended questionnaire based on the Community of Inquiry survey tool was used to collect students’ impressions and attitudes after they hadparticipated in the experimental study. The experiment consisted of control and experimental groups that partook in online group discussions as part of a regularly scheduled lesson. Findings – Digital collaborative tools were found to change the way in which students experience online group discussions. The attained rates of the Community of Inquiry were overall higher among students in the experimental group. Our findings tested to be statistically significant together with the effect size falling between medium to large extent. This further supports the notion that digital collaborative tools bring in a positive difference into online group discussions and have a potential to increase the quality of online learning when implemented carefully and thoughtfully. Implications – This study emphasizes the importance of developing a clear strategy of how to implement suitable digital collaborative tools into online learning in the most optimal manner that would increase the quality of online learning. This paper can be considered as a startingpoint for future research that could construct further knowledge within the field and extend our findings by investigating other aspects that have an influence on and can have beneficial effects for younger students in online education.

Cette thèse en sciences de gestion a pour objet de prendre la mesure du rôle du système d’information dans le déclenchement et la propagation des difficultés que rencontrent les petites et moyennes entreprises du secteur agro-alimentaire en France. Nous étudions le lien entre le désalignement des usages du système d’information et les difficultés que peuvent rencontrer les PME.Le terrain est constitué, d’un côté, par des enquêtes d’entreprises qui permettent de construire un indicateur synthétique de performances et, de l’autre côté, par l’enquête COI-TIC de 2006 dont nous obtenons quatre jeux d’indicateurs liés à l’usage du système d’information.À l’aide d’une démarche compréhensive, nous caractérisons ainsi le rôle du système d’information et son désalignement dans les dynamiques de performances. Nous montrons, au cas des PME des IAA, notamment l’importance de la coordination électronique (inter entreprise et entre les parties prenantes) et la place majeure des changements impliquant des projets informatiques. Enfin, les entreprises, quelles que soient leurs performances, rencontrent d’importantes difficultés d’appropriation des usages du système d’informationThe purpose of this thesis in management science is to assess the role of Information Systems in triggering and propagating the kind of problems faced by small and medium-sized enterprises in the food industry in France. The thesis will explore the relationship between misalignments in the uses of Information Systems and the difficulties with which SMEs are often confronted.The field of research is composed, on the one hand, of company surveys, used to elaborate a composite performance indicator, and on the other, the 2006 COI-TIC survey, from which four sets of indicators concerning the uses of Information Systems were extrapolated.Applying a comprehensive approach, the thesis defines the impact of the misalignment of Information Systems on performance dynamics. It also highlights, notably, the importance for SMEs in the food industry of IT coordination between companies and between those companies and their stakeholders, and examines the central role of changes involving IT projects. Lastly, regardless of their performances, companies face major difficulties in appropriating uses of Information Systems

Transportsektorn är en av de sektorer som står för en stor andel utsläpp. Transporter står för cirka en tredjedel av Sveriges utsläpp av växthusgaser. För att minska denna siffra har flera kommunala samt privata initiativ startats. Ett av dem är företaget i fråga som detta arbete är gjort tillsammans med.Huvudsyftet med vårt arbete var att ta fram faktisk data i form av en simulering för att kunna styrka att detta privata initiativ faktiskt var ett grönare alternativ samt att kunna förmedla detta på ett bra och metodiskt sätt för användaren via en prototyp. Simuleringen gjordes på äldre data från företaget på faktiskt körda transporter. Prototypen är ett interaktivt verktyg för användaren för att se vilka effekter deras tänkta agerande kan åstadkomma. Kan man nu med denna prototyp få användare att bli mer villiga att använda sig utav tjänsten? Och är de beredda att betala mer när de ser vilka effekter det skulle ge? Detta undersöktes i form utav en användarundersökning. Vad simuleringen visade var att samlastning av gods är avsevärt mycket bättre gällande Co2-utsläpp, än att transportera godset själv. Utöver detta visade prototypen i samarbete med användarundersökningen att slutanvändare tyckte om utformningen utav prototypen samt att budskapet förmedlades, dvs vilka minskade Co2 utsläpp som kunde göras. Våra resultat visar på att budskapet om Co2:s påverkan hade tagit emot av användarna. Samt att de var villiga att betala 21% högre belopp för dessa typer av tjänster, med motivering att det skulle vara bra för miljön.The transport sector is one of the sectors that accounts for a large proportion of emissions. The transport sector accounts for about one third of Sweden's greenhouse gas emissions. To reduce this figure, several municipal and private initiatives have been started. One of them is the company in question with which this work has been written.The main purpose of our work was to produce actual data in the form of a simulation in order to prove that this private initiative was actually a greener alternative, and to be able to convey this in a good and methodical way for the user via a prototype. The simulation is done on older data from the company on actual transports. The prototype is an interactive tool for the user to see what effects their intended actions can bring. With this prototype, can users now be more willing to use the service? And are they prepared to pay more when they see what effects it would give? This was tested in the form of a user survey. This meant that the user was first asked about why they would like to use this form of service and what sums they were prepared to pay for a specific transport.Then they sat down and tested the prototype and entered various transports and goods to transport then saw what effects they had. Then they were asked what they thought of the prototype and the information they received, and what motivations they had to use the service or similar services. Lastly they were asked what amounts they were prepared to pay for this form of service.What the results show is that the simulation resulted in the collective transportation of goods being considerably much better with respect to Co2 emissions, than if it were to be transported by itself. In addition to this, the prototype in collaboration with the user survey showed that end users liked the design of the prototype and that the message that was conveyed, ie which reduced Co2 emissions could be done. This ended with the users' motivations for using this or similar services were similar to before, but this turn Co2 jumped up to one of the leading reasons, even when it wasn't a motivation at all before when they stated before they tested the prototype. As well as they were now willing to pay up to 21% higher amount for these types of services, justifying that it would be good for the environment.

Although finance has been studied for thousands years, behavioral finance which considers the human behaviors in finance is a quite new area. Behavioral finance theories, which are based on the psychology, attempt to understand how emotions and cognitive errors influence individual investors’ behaviors (investors mentioned in this study are refered to individual investors). The main objective of this study is exploring the behavioral factors influencing individual investors’ decisions at the Ho Chi Minh Stock Exchange. Furthermore, the relations between these factors and investment performance are also examined. As there are limited studies about behavioral finance in Vietnam, this study is expected to contribute significantly to the development of this field in Vietnam. The study begins with the existing theories in behavioral finance, based on which, hypotheses are proposed. Then, these hypotheses are tested through the questionnaires distributed to individual investors at the Ho Chi Minh Stock Exchange. The collected data are analyzed by using SPSS and AMOS soft wares. Semi-structured interviews with some managers of the Ho Chi Minh Stock Exchange are conducted to have deeper understanding of these behaviors. The result shows that there are five behavioral factors affecting the investment decisions of individual investors at the Ho Chi Minh Stock Exchange: Herding, Market, Prospect, Overconfidence-gamble’s fallacy, and Anchoring-ability bias. Most of these factors have moderate impacts whereas Market factor has high influence. This study also tries to find out the correlation between these behavioral factors and investment performance. Among the behavioral factors mentioned above, only three factors are found to influence the Investment Performance: Herding (including buying and selling; choice of trading stocks; volume of trading stocks; speed of herding), Prospect (including loss aversion, regret aversion, and mental accounting), and Heuristic (including overconfidence and gamble’s fallacy). The heuristic behaviors are found to have the highest positive impact on the investment performance while the herding behaviors are reported to influence positively the investment performance at the lower level. In contrast, the prospect behaviors give the negative impact on the investment performance.

Dissertação de Mestrado Integrado em Medicina VeterináriaA cirurgia com laser de CO2 tem como principais benefícios menor grau de dor, menos hemorragia, menos infeções, menos edema, rubor e desconforto pós-cirurgico, proporciona ao paciente a capacidade de retomar as suas atividades normais mais cedo com um menor tempo cirúrgico e um campo cirúrgico mais limpo. Inicialmente utilizado na Medicina Humana foi adaptado para a Medicina Veterinária mas ainda em processo de expansão. O presente estudo foi desenvolvido numa amostra de 14 animais (n = 14) pertencentes à espécie Canis familiaris sendo 10 fêmeas (71,5%) e 4 machos (28,5%) com média de idade de 3,8 anos, com mínimo de 6 meses e máximo de 9 anos e com peso médio de 13,06 kg, com mínimo de 3 kg e máximo de 35 kg, sujeitos a ovariohisterectomia (OVH) e castração respectivamente. Foram divididos em 2 grupos N1 = incisão com lâmina de bisturi e N2 = incisão com laser de CO2, sendo 7 animais em cada grupo. Todos os animais receberam o mesmo protocolo pré-cirúrgico constituido por amoxicilina e meloxican, acepromazina e tramadol. A indução anestésica foi realizada com propofol, sendo a manutenção realizada com isoflurano. O objetivo do estudo foi comparar o uso do laser de CO2 com o uso do bisturi em incisões cirúrgicas. Os parâmetros utilizados foram 1) Exames auxiliares : medidas do número dos leucócitos (WBC) em T0, T1 e T2, albumina e proteinas totais (PTT) em T1 e T2, 2) avaliação da região incidida quanto a presença de reação inflamatória como rubor, edema, formação de exsudado em T1 e T2, espessura da região incidida em T1 e T2 e cicatrização estética T3, sendo T0 = antes da incisão, T1 = 24h após incisão, T2 = 8 dias após incisão e T3 = 30 dias após incisão. Os resultados puderam sugerir que não houve diferenças estatísticas entre os grupos em N1 e N2 quanto a albumina (p = 0,87), quanto a PTT (p = 0,53) e espessura em T1 (p = 0,87) e em T2 ( p = 0,73). Em relação a dor notamos que houve diferença entre os grupos N1 e N2 em T1(p = 0,001) com aumento da dor em N1. Em T2 não houve presença de dor nos 2 grupos. Em relação a WBC não notou-se diferença entre N1 e N2 em T1 (p = 0,90) mas em T2 houve diferença (p = 0,001) com aumento de WBC em N2.
ABSTRACT - SURGICAL INCISIONAL WITH SCALPEL TECHNIQUE VERSUS CO2 LASER: COMPARATIVE STUDY OF THE DEVELOPMENT OF THE HEALING PROCESS - The main advantages of the CO2 laser surgery are lesser pain, lesser bleeding, lesser probability of infections, lesser post-surgical swelling and discomfort, giving the patient the ability to restart his normal activities earlier with lesser surgical time and a cleaner surgical field. It was first used in Human Medicine and then adapted to Veterinary Medicine, but it's still in the developmental process. The current study has been developed on a sample of 14 animals (n = 14) of the canine species, with 10 females (71,5%) and 4 males (28,65%), medium age of 3,8 years old, with a minimum of 6 months and maximum of 9 which were subjected to ovariohysterectomy (OVH) and neutering. They were split in 2 groups: N1= use of a scalpel and N2 = use of CO2 laser, with 7 animals on each group. All the animals received the same pre-surgical protocol form of amoxicillin and meloxicam, acepromazine and tramadol. Anesthesia was induced with propofol and maintained with isoflurane. The aim of this study is to analyze the advantages of using CO2 laser instead of the scalpel in a surgical section. The evaluated parameters were 1) Complementary exams: measures of the number of white blood cells (WBC) (T0, T1 and T2), albumin and total protein (T1 and T2); 2) evaluation on the incised region, regarding inflammation like redness, edema, exudate (T1 and T2), thickness of the sectioned region (T1 and T2) and cosmetic scarring (T3), with T0 = before section, T1 = 24h after section, T2 = 8 days after the cut and T3 = 30 days after section. The results suggested that there wasn’t any statistic difference between groups in N1 and N2 regarding albumin (p = 0,87), concerning PTT (p = 0,53) and thickness (p = 0,87) and in T2 (p = 0,73). Concerning pain, we see there was a difference between groups N1 and N2 in T1 (p = 0,001) with augmented pain in N1. There wasn’t presence of pain in T2 on both groups. Regarding the WBC no difference was noted between N1 and N2 in T1 (p = 0,90) but it was registered a difference in T2 (p = 0,001) with augmented WBC in N2.

Resumo:
Pelagic and demersal cod (Gadus Morhua) specimens were collected respectively during a pelagic and a demersal survey in the Eastern Baltic sea in the fourth quarter of the years 2015-2017. Stomach contents were analysed and compared for the purpose of evaluating differences in the diet among pelagic and demersal specimens. Furthermore, generalized additive models (GAMs) were employed to investigate the daily fluctuations of stomach content weights of this predator. My results showed significant differences in the diet composition of demersal and pelagic cod mainly attributable to the higher weight share of sprat in the pelagic stomachs. Moreover, a remarkable diel variation in the stomach contents weights was present, indicating morning and evening peaks. The present study furnished novel insights into cod feeding pattern in the South-Western Baltic Sea. The implications of these findings for stock assessment multispecies models are also briefly discussed.

"This thesis presents a single-slice based fast stereotactic registration and tracking technique along with a corresponding modular system for guiding robotic mechanism or interventional instrument to perform needle-based interventions under live MRI guidance. The system can provide tracking of full 6 degree-of-freedom (DOF) in stereotactic interventional surgery based upon a single, rapidly acquired cross-sectional image. The whole system is constructed with a modular data transmission software framework and mechanical structure so that it supports remote supervision and manipulation between a 3D Matlab tracking user interface (UI) and an existing MRI robot controller by using the OpenIGTLink network communication protocol. It provides better closed-loop control by implementing a feedback output interface to the MRI-guided robot. A new compact fiducial frame design is presented, and the fiducial is wrapped with a passive resonant coil. The coil resonates at the Larmor frequency for 3T MRI to enhance signal strength and enable for rapid imaging. The fiducial can be attached near the distal end of the robot and coaxially with a needle so as to visualize target tissue and track the surgical tool synchronously. The MRI-compatible design of fiducial frame, robust tracking algorithm and modular interface allow this tracking system to be conveniently used on different robots or devices and in different size of MRI bores. Several iterations of the tracking fiducial and passive resonant coils were constructed and evaluated in a Phillips Achieva 3T MRI. To assess accuracy and robustness of the tracking algorithm, 25 groups of images with different poses were successively scanned along specific sequence in and MRI experiment. The translational RMS error along depth is 0.271mm with standard deviation of 0.277mm for totally 100 samples. The overall angular RMS error is less than 0.426 degree with standard deviation of 0.526 degree for totally 150 samples. The passive resonant coils were shown to significantly increase signal intensity in the fiducial relative to the surroundings and provide for rapid imaging with low flip angles. "

The use of calcineurin inhibitors (CNI) is the basis of many immunosuppressive regimens because of its clinical success and contribution to the remarkable increase in the rate of allograft survival. However, standard recommended doses of cyclosporine and tacrolimus are associated with nephrotoxicity, resulting in long term renal dysfunction. An ideal strategy would employ a CNI-free regimen. Attempts to convert heart and liver transplant patients to rapamycin resulted in an improvement in renal function however the incidence of side effects lead to dose reduction or drug discontinuation in many cases. Anti-CD25 monoclonal antibodies (mAb) have been used in induction immunosuppression and have been shown to reduce the incidence of acute rejection in solid organ transplantation. We have used anti-CD25 mAb for maintenance immunosuppression as a substitute to CNI in patients with chronic kidney disease. It was of our particular interest to examine the impact of immunosuppressive medications such as CNI, rapamycin and anti-CD25 monoclonal antibody on naive T helper cell differentiation. We hypothesize that as a result of their diverse mechanisms of action, the effect of immunosuppressive medication on CD4 T helper cells (Th1, Th2 and Th17) results in variability. We found that Th1 and Th17 cells as a proportion of CD4 cells and total lymphocytes in heart transplant patients are lower in CNI patients when compared to anti-CD25 mAb patients and healthy controls. We also found that Th17 cells as a proportion of CD4 cells in liver transplant patients are higher in patients on anti-CD25 mAb and rapamycin when compared to healthy controls. We wanted to determine if this variability had implications for graft rejection as well as two common complications of immunosuppression which are infection and malignancy however we did not find any correlation between proportions of T helper cells and rates of rejection, infection and malignancy.L'utilisation des inhibiteurs de la calcineurine (ICN) est la base de plusieurs traitements immunosuppresseurs en raison de son succès clinique et de sa contribution à l'augmentation remarquable du taux de survie des allogreffes. Cependant, les doses standards recommandées de cyclosporine et de tacrolimus sont associées à des néphrotoxicités, résultant en un dysfonctionnement rénal à long terme. Une stratégie idéale serait d'employer un régime sans ICN. Des tentatives de transférer les patients ayant subis des transplantations cardiaques et hépatiques à la rapamycine ont entraîné une amélioration de la fonction rénale. Cependant, l'incidence des effets secondaires a conduit à la réduction de la dose ou l'arrêt du médicament dans beaucoup de cas. Les anticorps monoclonaux anti-CD25 (AcM anti-CD25) ont été utilisés dans l'immunosuppression initiale et se sont dévoilés comme réducteurs du risque de rejet aigu lors de transplantations d'organes solides. Nous avons utilisé AcM anti-CD25 pour des fins d'immunosuppression de maintien comme substitut aux inhibiteurs de la calcineurine chez les patients atteints de maladie rénale chronique. Il était particulièrement dans notre intérêt d'examiner l'impact des médicaments immunosuppresseurs comme les ICN, la rapamycine et AcM anti-CD25 sur la différenciation des cellules T helper CD4. Nous émettons l'hypothèse que, suite à leurs diverses mécanismes d'action, les effets des médicaments immunosuppresseurs sur les lymphocytes T CD4 helper (Th1, Th2 et Th17) sont variables. Nous avons trouvé que les cellules Th1 et Th17 comme une proportion de cellules CD4 et lymphocytes totaux, chez les patients a transplantation cardiaque, sont moins élevées chez les patients ICN comparativement aux patients AcM anti-CD25 et les contrôles sains. Nous avons aussi trouvé que les cellules Th17 comme une proportion de cellules CD4 chez les patients a transplantation hépatique sont plus élevées chez les patients sur AcM anti-CD25 et la rapamycine, par rapport aux contrôles sains. Nous voulions déterminer si cette variabilité a des implications dans le rejet du greffon ainsi que dans deux complications fréquentes de l'immunosuppression, qui sont les infections et la malignité. Toutefois, nous n'avons pas trouvé de corrélation entre les proportions de cellules T helper et les taux de rejet, d'infection et la malignité.

Resumo:
The CO2SINK (and CO2MAN) project is the first onshore CO2 storage project in Europe. The research site is located near the town of Ketzin, close to Potsdam in Germany. Injection started in June 2008, with a planned injection target of 100,000 tonnes of CO2. In February 2011, around 45, 000 tons of CO2 had been injected into the saline aquifer at an approximate depth of 630 m. This thesis focuses on time-lapse analysis of borehole seismic data, surface seismic data and reservoir characterization at the Ketzin site. Baseline Moving Source Profiling (MSP) data were acquired in the borehole Ketzin 202/2007 (OW2), along seven lines in 2007. The zero-offset Vertical Seismic Profile (VSP) data were acquired in the same borehole. The main objective of the VSP and MSP survey was to generate high-resolution seismic images around the borehole. After modeling and data processing, the sandy layers within the Stuttgart Formation can potentially be imaged in the VSP and MSP data whereas reflections from these layers are not as clearly observed in the 3D surface seismic data. 2D and pseudo-3D time-lapse seismic surveys were conducted at the Ketzin site. Interpretation of 2D baseline and repeat stacks shows that no CO2 leakage related time lapse signature is observable where the 2D lines allow monitoring of the reservoir. This is consistent with the time-lapse results of the 3D surveys showing an increase in reflection amplitude just centered around the injection well. The results from the pseudo-3D surveys are also consistent with the 3D seismic time-lapse studies and show that the sparse pseudo-3D geometry can be used to qualitatively map the CO2 in the reservoir with significantly less effect than the full 3D surveying. The 2nd pseudo-3D repeat survey indicates preferential migration of the CO2 to the west. There are no indications of migration into the caprock on either of the repeat surveys. Amplitude Versus Offset (AVO) analysis was performed on both 2D and 3D repeat surveys. A Class 3 AVO anomaly is clearly observed on the 3D repeat data and matches the synthetic modeling well. No AVO anomaly was observed on the 2D repeat data, which was anticipated, but the result shows signs of a pressure response at the reservoir level in the data. Reflection coefficients were calculated using surface seismic data (3D and pseudo-3D) at the site. Pre-injection calculations agree well with calculations from logging data. Post-injection calculations are in general agreement with the seismic modeling, but generally show higher amplitudes than those expected. The full 3D data show a better image of the reflection coefficients before and after injection than the pseudo-3D data and can potentially be used to make quantitative calculations of CO2 volumes. The pseudo-3D data only provide qualitative information.

Context. Color can be used to convey allot of information but in particularly when it comes to tellingwho is good and who is evil. The most common color to use when displaying good and evil is blue forgood and red for evil. Objectives. This study will take a look at what colors people automatically associated with good andevil respectively. Methods. The two methods that are used in this paper is a survey in the form of a questionnaire andthe second method is a statistical hypothesis testing that was done on the data collected in the survey.The statistical hypothesis testing was done in the form of a chi-square test. From the chi-square testyou get a chi-square value and a p-value. Results. The result of the survey was that most participants thought of green, white and blue as goodcolors, while black and red where thought of as evil. The statistical hypothesis testing revealed thatthere where a significant statistical difference when comparing two colors in all but two cases. Thosecases where white vs. blue and orange vs. purple. Conclusions. The conclusions that can be drawn are that there is a significant statistical differencebetween how a color is perceived as good or evil. The perceived convention for what a good charactershould have, as a color is that it should be green and the perceived convention for an evil character isthat it should be either red or black.

Human behaviour produces massive greenhouse gas emissions, which trigger climate change and more unpredictable weather conditions. The fluctuation of daily weather corresponds to variations of everyday travel behaviour. This influence, although is less noticeable, can have a strong impact on the transport system. Specifically, the climate in Sweden is becoming warmer in the recent 10 years. However, it is largely unknown to what extent the change of travel behaviour would respond to the changing weather. Understanding these issues would help analysts and policy makers incorporate local weather and climate within our policy design and infrastructure management. The thesis contains eight papers exploring the weather and climate impacts on individual travel behaviour, each addressing a subset of this topic. Paper I explores the weather impact on individual’s mode choice decisions. In paper II and III, individual’s daily activity time, number of trips/trip chains, travel time and mode shares are jointly modelled. The results highlight the importance of modelling activity-travel variables for different trip purposes respectively. Paper IV develops a namely nested multivariate Tobit model to model activity time allocation trade-offs. In paper V, the roles of weather on trip chaining complexity is explored. A thermal index is introduced to better approximate the effects of the thermal environment. In paper VI, the role of subjective weather perception is investigated. Results confirm that individuals with different socio-demographics would have different subjective weather perception even given similar weather conditions. Paper VII derives the marginal effects of weather variables on transport CO2 emissions. The findings show more CO2 emissions due to the warmer climate in the future. Paper VIII summaries the existing findings in relations between weather variability and travel behaviour, and critically assesses the methodological issues in previous studies.QC 20160516

Resumo:
Dissertação de Mestrado Integrado em Medicina VeterináriaAnimais de raças braquicéfalas como o Bulldog Inglês e Francês, o ShiTzu, o Pug e o Pequinois apresentam uma popularidade crescente na nossa sociedade. A síndrome respiratória do braquicéfalo assenta em múltiplas alterações anatómicas que incluem a estenose das narinas, o alongamento do palato mole, os turbinados aberrantes, a hipoplasia da traqueia, a eversão dos sacos laríngeos e colapso laríngeo. Estas características obstruem o fluxo de ar através das vias aéreas superiores, causando uma sintomatologia que se traduz, na sua maioria, em sinais respiratórios como dispneia, apneia, roncos, estertores, intolerância ao exercício e ao calor, vómitos, regurgitação e cianose. O stress respiratório devido a obstrução das vias aéreas superiores e o sobreaquecimento causado por uma termorregulação deficiente estão entre as circunstâncias que causam maior risco de vida e têm um papel importante na deterioração da qualidade de vida destes animais. O presente estudo prospetivo teve como objetivo avaliar os resultados obtidos com a palatoplastia e rinoplastia a laser CO2 em cães braquicéfalos. Foram acompanhados 11 casos clínicos, de dez animais da raça Bulldog Francês e um da raça Pequinois, com idades compreendidas entre os 4 meses e os 3 anos de idade. A cirurgia a laser CO2 apresentou vantagens evidentes, nomeadamente na redução da hemorragia, da dor, do tempo anestésico e do edema pós-cirúrgico, permitindo, por isso, uma recuperação mais rápida dos animais. Dada a crescente popularidade das raças braquicéfalas e tendo em conta as suas características anatómicas particulares, urge a necessidade de adaptação da consulta médica de rotina, onde seja feita uma avaliação precoce do risco de desenvolvimento da síndrome respiratória obstrutiva e de outros problemas que lhes são característicos.
ABSTRACT - Approach to the brachycephalic dog – Surgical correction of the anatomical abnormalities of the upper airways with CO2 laser and adapted medical exam proposal - Brachycephalic breed animals like French and English Bulldog, Shi Tzu, Pug and Pequinois have multiple anatomical changes which lead to brachycephalic airway syndrome. These changes which include stenotic nares, elongated soft palate, abnormal nasopharyngeal turbinates, tracheal hypoplasia, laryngeal saccule eversion and collapse. These changes obstruct the airflow in the upper airways, causing a variety of symptoms that involve respiratory signs like dyspnea, apnea, snoring, stertor, heat and exercise intolerance, vomiting, regurgitation and cyanosis. Respiratory stress due to upper airway obstruction and overheating caused by poor thermoregulation are among the most life-threatening circumstances and play an important role in the deterioration of the quality of life of these animals. However, sleep, food and physical activity are basic needs that are also affected in the brachycephalic and the difficulty in performing these tasks leads to an additional decline in their quality of life. The present prospective study aimed to evaluate the results obtained with CO2 laser rhinoplasty and palatoplasty in brachycephalic dogs. Eleven clinical cases of ten French Bulldogs and one Pequinois, aged between 4 months and 3 years old, were followed. Surgery with CO2 laser has shown important advantages, namely reducing bleeding, post-surgical oedema, minimize pain, anesthesia time and, thereby, a much faster recovery of the animals. Given the increasing popularity of these breeds and their particular anatomical characteristics, the need for adaptation of the routine medical exam is urgent, acting early to safeguard both the welfare of these animals and their responsible breeding.

In the last decades the world has seen great dissemination of powerful brands, local and world-known, not infrequently assessed in billions of dollars, leading to massive sales of products and services associated with them. And in that context it is clear the impact of the intrinsic value of the intangible assets brand of companies in mergers and acquisitions.Nowadays, it has been clear that a Company valuation has a relevant amount related to intangible assets and, among these, brands have significant importance. This study aimed to investigate what is the general perception, the control method and the valuation of brands on companies operating in Brazil, by gathering information about the companies where students and recent graduates of post-graduate in business administration related courses used to work.Thus, from the sample group of 134 companies operating in Brazil, were extracted details of five dimensions of brand: awareness about its importance, financial valuation of the brand,accounting recognition of brand value, management of this intangible asset and its use as a tactical and strategic performance ratio. The methodology used was a survey that, from statistical tests Chi-square Pearson test led to the conclusion that there is no significant relationship between the fact that companies sell products and services and aspects relating to each of the five dimensions studied. Other variables statistically compared by using the chisquare test meant for the sample companies, among other findings, the significant correlation between large companies and the fact that companies evaluate brands or negotiate them. Also, the study took into account the criteria of attitude scores of respondents based on the Likert scale. The resulting data reveal that the brands are still in need of greater attention from companies. It is a minority in the sample studied the incidence of financial valuation of the brand, as well as the proper focus on accounting and management reports. Internal control over brand management and variable compensation system based on ratios of the brand,though present, such items were observed in low intensity in the sample companies.
Nas últimas décadas o mundo tem assistido à grande proliferação de marcas poderosas, local e mundialmente conhecidas, avaliadas não raramente em bilhões de dólares, levando a vendas em massa de produtos e serviços a elas associadas. E nesse contexto é notório o impacto do valor intrínseco do ativo intangível marca no valor das empresas em movimentos de fusões e aquisições. Hoje sabe-se que um valuation conta com parte relevante de seu montante relacionado a ativos intangíveis e, entre tais, as marcas possuem significativo destaque. Este trabalho objetivou investigar qual é a percepção geral, o método de controle e a avaliação das marcas em companhias em operação no Brasil, a partir de levantamento de informações sobre as empresas em que trabalhavam estudantes e recém egressos de cursos de pós-graduação profissional em áreas ligadas à administração de negócios. Assim, da amostra pesquisada de 134 companhias atuantes no país, foram extraídos detalhes de cinco dimensões da marca:percepção sobre sua importância, avaliação financeira, reconhecimento contábil de seu valor,gestão desse ativo intangível e de seu uso como indicador de performance tática e estratégica. A metodologia utilizada foi um levantamento (ou survey) que, a partir de testes estatísticos qui-quadrado de Pearson , permitiu a constatação de que não há relacionamento significativo entre o fato das empresas comercializarem produtos e serviços e aspectos ligados a cada uma das cinco dimensões estudadas. Outras variáveis comparadas estatisticamente pelo teste de qui-quadrado resultaram para as companhias da amostra, entre outras constatações, a significativa correlação entre as empresas de grande porte e o fato das empresas avaliarem marcas ou as negociarem. O estudo também levou em conta o critério de escores de atitudes dos respondentes baseado na escala Likert. Os dados resultantes revelam que as marcas carecem ainda de maior atenção por parte das empresas. É minoritária na amostra estudada a incidência de avaliação financeira da marca, assim como o devido enfoque em relatórios contábeis e gerenciais. Os controles internos de gestão da marca e o sistema de remuneração variável baseado em indicadores da marca, embora existam, mostraram-se itens pouco observados nas companhias da amostra.

A exceção neste quadro é o carcinoma de lábio, que por características próprias são, em sua maioria, diagnosticados em estágios iniciais. Particularidades inerentes ao tratamento cirúrgico, que é a terapêutica de escolha, faz com que a maioria dos cirurgiões optem pela realização da cirurgia sob anestesia geral No atual estudo procuramos observar, por meio de avaliação clinica, o benefício obtido quando do uso da radiação laser de CO2 como ferramenta de diérese na terapêutica cirúrgica desta patologia quando realizada ambulatorialmente. Selecionamos 9 pacientes portadores de carcinoma epidermóide de lábio inferior no estádio T1N0M0 e 1 no estádio T2N0M0 que foram submetidos a exerése da neoplasia em ambulatório com uso da radiação laser de CO2, com dose de potência de 7 Watts (1 paciente) e 5 Watts (9 pacientes}. Concluímos ser a radiação laser de CO2, na dose de 5 Watts, uma ferramenta extremamente útil proporcionando um campo cirúrgico exangue, a determinação das margens de segurança (radicalidade) na ressecção da doença com extremo conforto e contribui com o princípio oncológico da centripeticidade ao promover o selamento dos vasos sanguíneos e linfáticos. O resultado funcional e estético observado nos pacientes submetidos ao tratamento foram de excelente qualidade
The absence of a policy of adequate prevention transforms malignant lesions of the oral cavity, which are easily detectable in initial stage, in a pathology almost always diagnosed in an advanced evolutionary state. The exception in this case is the lip carcinoma, which proper characteristics are, in majority, diagnosed in initial stages. lnherent particularities to the surgical treatment, that is the choice therapeutics, makes that the most surgeons opt by the accomplishment of the surgery under general anesthesia. In the current study we propose to observe, by means of clinical evaluation, the benefit obtained when of the use of the CO2 laser radiation as a dieresis tool in the surgical therapeutics of this pathology when make in ambulatory room. We select 9 patients with squamous cell carcinoma in inferior lip, in the stadium T1N0M0 and 1 in the stadium T2N0M0 who were submitted for exeresis in ambulatory with use of the laser CO2 radiation, with power of 7 Watts (1 patient) and 5 Watts (9 patient). We conclude be the CO2 laser radiation, in the power dose of 5 Watts, is an extremely useful tool providing a clean surgical field, the determination of the safety margins (radicalit) in resection of the disease with extreme comfort and contributed with the oncological principle of centripecity when promoting the sealing of the blood and lymphatic vessels. The functional and aesthetic results observed in the patients submitted to the treatment went of excellent quality
