Avaliação do Seio Maxilar: Radiografia Panorâmica Versus Tomografia Computadorizada de Feixe Cônico

O objetivo deste estudo retrospectivo implica em comparar a presenca de velamento, o espessamento de mucosa e a presenca de septo no seio maxilar em radiografias panorâmicas e tomografias computadorizadas de feixe conico (TCFC). A amostra foi composta por 100 pacientes do arquivo, que apresentavam as radiografias panorâmicas e as TCFC antes do inicio do tratamento ortodontico, sendo 57 mulheres e 43 homens, com media de idade de 19,08 anos. Foram incluidas nesta pesquisa apenas os exames que apresentavam boa qualidade e bom posicionamento do paciente. A avaliacao do velamento, espessamento de mucosa e presenca de septo no seio maxilar foi realizada por um unico examinador calibrado, de forma independente, nas radiografias e nas TCFC. A concordância entre os exames foi avaliada por meio do teste Kappa. Os resultados demonstraram boa concordância entre as radiografias panorâmicas e TCFC (Kappa entre 0,62 a 0,72), com -90, -88 e 89% de convergencia entre os metodos, para velamento do seio maxilar; espessamento de mucosa e presenca de septo no seio maxilar, respectivamente. Pode-se concluir que foi encontrada concordância satisfatoria na avaliacao do velamento, espessamento de mucosa e presenca de septo no seio maxilar entre as radiografias panorâmica e TCFC. Dessa forma, as caracteristicas do seio maxilar foram identificadas, de maneira semelhante, na radiografia panorâmica e na TCFC. Palavras-chave: Tomografia Computadorizada por Raios X.

Abstract The objective of this retrospective study was to compare the presence of filled maxillary sinus, mucosal thickening and the presence of septum in the maxillary sinus on panoramic radiographs and concomitant computed tomography (CBCT) scans. The sample consisted of 100 patients from the archive who presented the panoramic radiographs and the CBCT before the beginning of the orthodontic treatment, being 57 women and 43 men, with a mean age of 19.08 years. Only the exams that presented good quality and good positioning of the patient were included in this study. The evaluation of the presence of filled maxillary sinus, mucosal thickening and the presence of septum in the maxillary sinus was performed by a single examiner, regardless of who was calibrated on panoramic radiograph and CBCT. The agreement among the exams was assessed by means of Kappa test. The results showed good agreement between panoramic radiograph and CBCT (Kappa between 0.62 and 0.72), with -90, -88 and 89% convergence between the methods, for the presence of filled maxillary sinus, mucosal thickening and presence of septum in the maxillary sinus, respectively. It can be concluded that satisfactory agreement was found in the evaluation of the the presence of filled maxillary sinus, mucosal thickening and presence of septum in the maxillary sinus between the panoramic and CBCT radiographs. Thus, the characteristics of the maxillary sinus were similarly identified in panoramic radiography and CBCT. Palavras-chave: Tomography, X-Ray Computed. Radiography, Panoramic. Diagnosis.
Human dendritic cells accumulate in lung disease and contribute to serum IgE clearance via FcERI

Author(s): Greer, Alexandra | Advisor(s): Shin, Jeoung-Sook | Abstract: Dendritic cells are crucial for the development of the adaptive immune response and have also been implicated in a number of inflammatory diseases. Much of what we know about dendritic cell function is limited to mouse models of disease, as human DCs remain difficult to identify consistently and samples can be difficult to acquire. We undertook a study to identify the prevalence of BDCA1+ DCs in a panel of healthy and diseased lung donors by carefully and comprehensively identifying DCs in parenchymal lung tissue. We found a dramatic increase in the prevalence of BDCA1+ DCs in the fibrotic lung diseases idiopathic pulmonary fibrosis (IPF) and chronic hypersensitivity pneumonitis (HP) by flow cytometry. We also saw a significant increase in BDCA1+ DCs in Th2-high asthma by using the high-affinity IgE receptor, FcERI and MHCII as identification markers of DCs in biopsy sections. These increased numbers of BDCA1+ DCs could potentially contribute to disease and may represent a novel therapeutic target. Because of the potential role of FcERI in promoting Th2-mediated allergy via DCs, we also investigated regulation of this receptor on human DCs. Surprisingly, we found that human DCs and monocytes constitutively endocytose FcERI and IgE in the absence of crosslinking stimulus. Transgenic mice expressing human FcERIa showed similar FcERI regulation, which resulted in rapid human IgE endocytosis in blood DCs and monocytes in vivo. Serum IgE catabolism was accelerated in FcERI-transgenic mice and was significantly influenced by DC and monocyte numbers. DCs and monocytes may therefore contribute to serum IgE control through constitutive IgE endocytosis and could represent a novel therapeutic strategy for allergic conditions. Further work on the trafficking mechanism of FcERI regulation may provide a significant novel strategy for control of IgE-mediated allergies.
The Voice of the Child in Child Protection: Whose Voice?

Article 12 of the United Nations Convention on the Rights of the Child outlines the rights of children to express their views in decisions affecting their lives. There is further evidence to support the positive benefits for children who are afforded this right. However, evidence shows that despite legislative and policy frameworks to support this, repeated messages from inquiry reports highlight failures to do so. This paper draws upon research undertaken in Scotland but the findings of the study are relevant across the UK and beyond. Child protection documentation including reports and case conference minutes were analysed to assess to what extent the child’s views were presented to, and considered in, decision making forums. In particular the study considers how the child’s views and wishes are represented in writing, and highlights the ways which professionals filtered and interpreted the child’s view rather than presented it in its pure form. Messages have emerged identifying a need for workers to be clear about the factors which influence their practice with children. These include the value they place on children’s participation, the skills and confidence needed to engage children with complex needs and the impact of competing tensions. One example of such a tension is that between the needs of busy workers, and those of children who are potentially involved in a range of decision making processes.
The relationships between school belonging and students’ motivational, social-emotional, behavioural, and academic outcomes in secondary education: a meta-analytic review

ABSTRACT This meta-analytic review examines the relationships between students’ sense of school belonging and students’ motivational, social-emotional, behavioural, and academic functioning in secondary education. Moreover, it examines to what extent these relationships differ between different student groups (grade level, SES), measurement instruments, and region. The meta-analysis included 82 correlational studies, published in peer-reviewed journals between 2000 and 2018. Results revealed, on average, a small positive correlation with academic achievement, and small to moderate positive correlations with motivational outcomes such as mastery goal orientations; with social-emotional outcomes such as self-concept and self-efficacy; and with behavioural outcomes such as behavioural, cognitive, and agentic engagement. A small negative correlation is observed with absence and dropout rates. Similar results are found across different student groups (grade level, SES). Although the results vary to some extent across measurement instruments and region, generally, the results reveal that school belonging plays an important role in students’ school life.
Effect of Library Automation on Performance of Librarians in Private Universities in South-West Nigeria

This study focuses on effect of library automation on the performance of librarians in South-West, Nigeria. The survey research design was used. The population of the study was 349 librarians from 22 private university libraries in South-West Nigeria. 272 copies of the questionnaire were returned giving a return rate of 80.1%. Data collected were analyzed using descriptive statistics and Pearson’s Product Moment Correlation Coefficient. Findings revealed that out of the six library services identified in this study, five were fully automated and 90% of the private university libraries have automated their services. From the findings, librarians’ performance had been increased by 70% as a result of automated library in private universities in South West Nigeria. The study showed that there was significant and positive relationship between library automation and librarians’ performance in private university libraries (r =.372, p<.01). This study concluded that most private university libraries in South-West Nigeria were fully automated which allowed librarians to increase the quality of services rendered. Library service automation contribute greatly to librarians performance in private universities in South-West Nigeria. This study recommended that university library managers need to further enlighten both the library staff and library users on the importance of library automation by organizing workshops, seminars and conferences in order to meet the current information needs of users.

Automated Simulation Model Generation

One of today's challenges in the field of modeling and simulation is to model increasingly larger and more complex systems. Complex models take long to develop and incur high costs. With the advances in data collection technologies and more popular use of computer-aided systems, more data has become available in many organizations. This often allows for and requires a certain degree of automation in modeling. The research presented in this dissertation studied how to automatically generate simulation models. The method proposed uses domain specific model components as building blocks for model generation and applies graph transformation based algorithms to compose large simulation models according to the existing data. The method has been applied practically in the domain of light-rail transportation.
Epidural haematoma by Mayfield head-holder®. Case report and review of literature.

A lot of neurosurgical interventions require the use of a pin-type head-holder to immobilize the patients' head. We report the case of an epidural haematoma caused by penetration of head holders' pin in a 7-year-old boy. The haematoma was showed by a head CT-scan at the end of surgery performed to treat a cerebellar astrocytoma that was managed surgically. Mmany factors seem to contribute to elevate the risk of complications due to the use of the Mayfield head-holder. Prevention and management measures are discussed also through a review of literature.
ANALYZING THE EFFECT OF PRODUCTION RISK AND TIME PREFERENCE ON THE USE AND CHOICE OF IMPROVED LIVESTOCK FEEDING PRACTICE IN ETHIOPIA

A number of improved feeding practices such as stall feeding, rotational grazing, and tethering can help increase livestock productivity in Ethiopia. The main aim of this paper is to determine what factors affect the adoption of on such improved feeding practice; i.e. Stall Feeding (SF) and the choice of animal or season for its application. A bivariate probit model was estimated using observations from 367 rural farmers in Northern Ethiopia. Production risk and the frequency of shock are found to be key determinants. As expected, the results from bivariate model revealed that the expected yield positively influenced SF adoption decision and its full-year application while yield variability and risk of yield failure had a negative effect on SF adoption decision and its full-year application. Likewise, previous animal shocks positively contribute to SF adoption. The major contribution of this paper is its explicit treatment of production risk, shock and time preference in the decision to adopt and apply SF. Expected benefits that the farmer can derive from low production risk due to SF adoption should be included in the promotion agenda of SF practice. The implication is that intervention that reduces the variance of return and exposure to downside risk are some desirable in the adoption and choice decision .
Initial Coin Offering to Finance Venture Capital: A Behavioral Perspective

An initial coin offering (ICO) is the procedure whereby ventures raise capital by selling tokens to investors. Compared with traditional financing methods, ICOs are new and less understood by both the industry and academia. For example, the literature is not clear about which factors determine the success rate or the amount raised in an ICO. Existing literature (Fisch 2019) shows that the signals of the private information of an ICO’s high quality determine the amount of funding in the ICO. This article is the first in the literature that provides evidence that investor sentiment and investor awareness are determinants of the amounts raised in an ICO. Moreover, it provides evidence confirming the signaling hypothesis. Specifically, ICOs with a pre-ICO and with a higher rating are more likely to raise more funds. This article is the only one in the literature that uses the entire market of 4,367 ICOs to confirm its findings. The results extend the understanding of the dynamics of an ICO to the behavioral field and enable investors and practitioners to understand the crucial determinants of both ICO success rates and the amounts raised.

The state of human resource management: evidence from employees' views of HRM systems and staff. Состояние дел с HR-менеджментом: данные о взгляде работников на системы HRM и его персонал

Дается оценка состояния HRM. Ранее для оценки HRM применялись методы, проверявшие либо соответствие лучшей практике, либо непредвиденные расходы. Исследование точек зрения работников было предложено в качестве альтернативного метода. Именно этот метод использовался авторами данной статьи. Основу анализа составили данные опросов 2632 работников из 73 компаний. Согласно этим данным, к сильным сторонам HRM работники относили подготовку кадров и развитие, премии и уровни личной мотивации. Работники также высоко оценивали успехи персонала HR в ряде служб. Слабыми сторона HRM, по оценкам работников, являются комплектация персонала, найм и удержание работников, коммуникация, а также нравственный климат в организации в целом. Эти данные подтверждают смешанную, но в целом позитивную картину состояния дел с HRM на обследуемых предприятиях.
Price Pressure and Efficiency on FOMC Announcements

We examine the impact of the surge in trading activity following FOMC announcements on price discovery in the equity market, in particular in the highly liquid S&P 500 E-mini futures. In contrast to the hypothesis that all trading reflects learning about these public news announcements, we find that trading is associated with a decrease in price informativeness and order imbalances generate substantial price reversals reaching 60 basis points even at horizons of several hours. Our findings show that price pressure is prevalent in the most liquid assets following public news and have direct implications for measuring the impact of monetary policy news on equity prices.
Relative antigenicity of components in vascularized composite allotransplants: An experimental study of microRNAs expression in rat hind limb transplantation model

Skin is considered to be the most antigenic component of all vascularized composite allotransplantation tissues. However, no studies have used methods other than histological assessment to analyze the relative antigenicity of various components. In this study, we analyzed gene expression to investigate the relative antigenicity of each component in the transplanted limb.
Reception studies in live and pre-recorded subtitles for the deaf and hard of hearing

This chapter aims to provide an overview of reception research in the field of subtitling for the deaf and hard of hearing (SDH). Given that the development of reception research in this area is closely linked to the development of SDH as a professional practice and academic field of study, a historical approach has been adopted here. It starts from the origins of pre-recorded and live SDH in the US and Europe and continues with the first and often overlooked classroom-based experiments and large-scale user surveys that substantiated the introduction of TV subtitles in the 1970s and 1980s. The focus is then turned to the more specific parameters studied in the 1990s, followed by the first eye-tracking studies and the development of SDH as a field of study in Europe in the 2000s and, finally, the internationalisation and specialisation of the recent experimental (re)turn experienced by reception studies in SDH. The chapter concludes with a section on the scarce reception research conducted to date in the area of live SDH and with some final thoughts on the features, challenges and requirements of experimental research in this area.
The Accuracy of Frozen Section in the Diagnosis of Malignant Adnexal Masses Malign Adneksiyal Kitlelerin Tanisinda Donuk (Frozen) Kesit İncelemesinin Doğruluğu

Objective: To measure the accuracy of the frozen section in the diagnosis of malignant adnexal masses. Methods: 192 patients who had been operated due to adnexal masses and submitted for intraoperative frozen section were evaluated retrospectively. The results were compared with paraffin section. Results: In all cases, opinion on frozen section was available. The sensitivity of frozen section through benign, borderline and malignant tumors were 98.8%, 90% and 93.8% respectively, where as the specificity of the latter tumors were 92.3%, 98.9% and 100% respectively. The overall accuracy was 97.9%. Two benign cases were diagnosed as borderline, one borderline as benign and one malignant case as a benign in frozen section. The misdiagnosed malignant case was mucinous and the others were serous type tumors. Conclusion: Frozen section has high accuracy in the diagnosis of malignant ovarian tumors. Paraffin section is the gold standard method, but because of the need for the quick result in the operation for the surgical management, frozen section must be performed to all suspicious adnexal masses.
A Memory‐Efficient Block‐wise MAP Decoder Architecture

Next generation mobile communication system, such as IMT‐2000, adopts Turbo codes due to their powerful error correction capability. This paper presents a block‐wise maximum a posteriori (MAP) Turbo decoding structure with a low memory requirement. During this research, it has been observed that the training size and block size determine the amount of required memory and bit‐error rate (BER) performance of the block‐wise MAP decoder, and that comparable BER performance can be obtained with much shorter blocks when the training size is sufficient. Based on this observation, a new decoding structure is proposed and presented in this paper. The proposed block‐wise decoder employs a decoding scheme for reducing the memory requirement by setting the training size to be N times the block size. The memory requirement for storing the branch and state metrics can be reduced 30% to 45%, and synthesis results show that the overall memory area can be reduced by 5.27% to 7.29%, when compared to previous MAP decoders. The decoder throughput can be maintained in the proposed scheme without degrading the BER performance.
Generation of symbolic network functions using computer software techniques

Software techniques in data structure and special binary properties in computer words have been used for the development of a new computer program called SNAPEST for generating network functions in symbolic form. This new approach is found to save computer memory and time by considerable amounts, when compared to programs wellknown at present. Some examples are given at the end of this paper to illustrate the advantages and efficiency achieved by the program.
What I Learned in Medical School: Personal Stories of Young Doctors

uring a recent voyage from Norway to Rome, I carried five different texts for study purposes. These texts included a study about the increasing selfmedication of Finnish physicians during the latest decade; an editorial about Norwegian physicians who, due to alcohol and drug abuse, lost their medical licensure for a given period; a story told by a male physician who, as the father of a seriously ill physician, sees how his own and his son’s profession jeopardizes the son’s health and future and how his colleagues ignore the father’s professional skills and competence; a draft of my own contribution to a critical anthology on health care research; and another book, What I Learned in Medical School, a collection of 23 different voices telling about the general-yet-particular experience of studying medicine. All five texts shared a common theme, the way a physician lives in the world—or, more precisely, how each physician strives to retain his or her selfhood while becoming or being a doctor. This premise may seem strange; after all, there ought to be no tension—let alone mutual exclusion—between being one’s own person and being a physician, a helper for other people. Nonetheless, this tension is what all five of my texts—the study, the editorial, the story, the draft, and the book— were about. This tension is exactly what is discussed by the 23 young colleagues in What I Learned in Medical School, who reflect about their personal experiences of entering medical school and becoming socialized into the practice of medicine. In highly different ways, these 23 physicians describe their particular backgrounds, which reflect great variety: A female Korean naval officer strives to unite family life, gender roles, and her own ambitions; a single, black, previously teenage mother encounters humiliating structural prejudices in the obstetrical delivery ward; a Vietnamese boat refugee alienates himself by denying his past until he understands that he cannot heal others unless he heals himself; the grandson of four Holocaust survivors feels obliged to fulfill their lives’ purpose; a married young woman from a small town in Texas becomes “different” and strange in familiar What I Learned in Medical School: Personal Stories of Young Doctors Edited by Kevin M Takakuwa, Nick Rubashin, and Karen E Herzig With a foreword by Jocelyn Elders, former US Surgeon General
