Оцінка дефіциту міжальвеолярної висоти при проведенні компьютерної томографії у пацієнтів із дисфункції СНЩС при атрикуляційно-оклюзійних порушеннях
No full textThis article reviews the assessment of interalveolar height deficit in morphometric comparison with its projection onto the superior space of the temporomandibular joint (TMJ) using cone-beam computed tomography (CT) of the TMJ. The technique for calculating the gaps between the fossa and the head, determining the coefficients for their comparison, and their correlation with clinical signs of TMJ dysfunction in occlusal and articulatory disorders is described.
The aim - to determine CT diagnostic criteria for decreased interalveolar height in patients with functional TMJ disorders with occlusal and articulatory disorders at the stage of orthopedic treatment planning.
Materials and research methods. An examination was conducted of 150 patients with functional disorders of the chewing apparatus and occlusal disorders, who were included in the experimental group and 30 practically healthy individuals - the control group. Both groups were comparable in age and sex. Cone-beam tomography was performed on the MyRay Hyperion X9 PRO model with iRYS 16.3.1 software. During the clinical dental examination, the occlusion of the dentition was assessed, the reduction of the interalveolar height was determined, the width of the mouth opening was assessed, the mobility of the lower jaw was assessed, the symmetry of the mouth opening was determined, clicking and crunching in the TMJ were determined.
Research result. When analyzing cone-beam tomography data, interalveolar height deficiency was classified as a decrease in the proposed coefficient for assessing the size of the upper TMJ space in at least one joint. A decrease in the specified ratio was found in 130 (86.67 %) patients with TMJ dysfunction and occlusal and articulation disorders according to CT data and confirmed by the anatomical and physiological method in 81 (54.00 %) patients, while its moderate decrease was confirmed by measurements by the topographic and physiological method (0.5-2.5 mm) in 62 (76.54 %) people and a significant decrease (more than 2.5 mm) in 19 (23.46 %) people, in 20 (13.33 %) patients, the coincidence of the absence of interalveolar height deficiency according to CT data and the anatomical and physiological method was noted.
Bilateral reduction of interalveolar height was found in 82 (54.67 %) patients of the study group; 36 (24.00 %) of them had clinically observed pain syndrome. When assessing the deficiency of interalveolar height by the topographic-physiological method, confirmation of its moderate reduction (0.5-2.5 mm) was found in 51 (62.20 %) individuals and a significant reduction (more than 2.5 mm) in 8 (9.75 %) individuals. Unilateral reduction of interalveolar height was found in 48 (32.00 %) patients of the study group; 20 (41.66 %) of them had clinically observed pain syndrome.
Conclusions. The assessment of the size of the superior articular space in comparison with the average value of the anterior and posterior articular gaps when determining their sizes using cone-beam CT of the TMJ may be a marker of decreased interalveolar height in patients with TMJ dysfunction and occlusal and articulatory disordersУ цій статті розглядається оцінка дефіциту міжальвеолярної висоти у морфометричному співставленні з її проекцією на верхню щілину скронево-нижньощелепного суглоба (СНЩС) при виконанні комп’ютерної конусно-променевої томографії (КТ) СНЩС. Описується техніка обчислення щілин між ямкою і голівкою, визначення коефіцієнтів для їх порівняння і їх співставлення із клінічними ознаками дисфункції СНЩС при оклюзійно-артикуляційних порушеннях.
Мета – провести визначення КТ-діагностичних критеріїв зниження міжальвеолярної висоти у пацієнтів із функціональними розладами СНЩС при оклюзійно-артикуляційних порушеннях на етапі планування ортопедичного лікування.
Матеріали та методи дослідження. Проведено обстеження 150 пацієнтів із функціональними розладами жувального апарату й оклюзійними порушеннями, які увійшли до дослідної групи і 30 практично здорових осіб – контрольна група. Обидві групи співставними за віком і статтю. Проводилась конусно-променева томографія на апараті MyRay модель Hyperion X9 PRO із програмним забезпеченням iRYS 16.3.1. При клінічному стоматологічному огляді проводили оцінку оклюзії зубних рядів, визначення зниження міжальвеолярної висоти, оцінку ширини відкривання рота, оцінку рухомості нижньої щелепи, визначення симетричності відкривання рота, клацання і хрускіт в СНЩС.
Результати дослідження. При аналізі даних конусно-променевої томографії класифікували дефіцит міжальвеолярної висоти при зниженні запропонованого коефіцієнта оцінки величини верхньої щілини СНЩС хоча б в одному суглобі. Зниження вказаного співвідношення було встановлено у 130 (86,67 %) пацієнтів із дисфункцією СНЩС і оклюзійно-артикуляційними порушеннями за даними КТ і підтверджено анатомо-фізіологічним методом у 81 (54,00 %) пацієнтів, при цьому встановлено підтвердження її помірного зниження вимірами топографо-фізіологічним методом (0,5-2,5 мм) у 62 (76,54 %) осіб і значного зниження (більше 2,5 мм) у 19 (23,46 %) осіб, у 20 (13,33 %) пацієнтів відмічено співпадіння відсутності дефіциту міжальвеолярної висоти за даним КТ й анатомо-фізіологічного методу.
Двостороннє зниження міжальвеолярної висоти встановлено у 82 (54,67 %) пацієнтів дослідної групи, у 36 (24,00 %) із них клінічно спостерігали больовий синдром. При оцінці дефіциту міжальвеолярної висоти топографо-фізіологічним методом встановлено підтвердження її помірного зниження (0,5-2,5 мм) у 51 (62,20 %) особи і значного зниження (більше 2,5 мм) у 8 (9,75 %) осіб. Одностороннє зниження міжальвеолярної висоти встановлено у 48 (32,00 %) пацієнтів дослідної групи, у 20 (41,66 %) із них клінічно спостерігали больовий синдром.
Висновки. Оцінка величини верхньої суглобової щілини у співставленні із середнім значенням передньої задньої суглобових щілин при визначенні їх розмірів за допомогою конусно-променевої КТ СНЩС може бути маркером зниження міжальвеолярної висоти у пацієнтів із дисфункції СНЩС і оклюзійно-артикуляційними порушенням
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
