Relationship Between Passing and Ball Control in Soccer: Analysis of Variations of Kinematic Measures
Authors: Hasan Uday , Clemente Filipe Manuel 
Published: May 2021

Abstract

Introduction. A soccer player with good ball control is the one who is able to perform complex coordinated situational motor actions in a certain space and in as short time period as possible. The analysis included variations in the angle of the knee joint of the leg receiving a ball (AKLR), angle of the knee joint of the supporting leg (AKLS), angle between thighs (ABT), trunk bending angle (TBA), hip joint point height (HPH), and ball distance after controlling the ball (BDAC) between effective and ineffective passing in soccer.

Material and Methods. A total of 12 university soccer players (age: 20.8 ± .83 years old, experience: 4.7 ±.78 years) voluntarily participated in the study. The players made five attempts to control the ball with the inside foot. The best attempt was analysed for each case (effective and ineffective).

Results. The degrees of AKLR, AKLS, ABT, TBA and HPH were significantly greater in effective passing than those in ineffective passing; the observed effect sizes were 4.87, 2.53, 1.77, 3.98, and 3.40, respectively. BDAC was meaningfully greater at ineffective passing (effect size: 2.03).

Conclusions. There were significant differences in the values of kinematic variables used to test ball control by effective and ineffective passes (p < 0.05). The research sample, in terms of the values of kinematic variables, achieved noticeable progress during the performance of ball control for effective passing, which showed its effectiveness in reducing the distance after controlling the ball.

Abstract

Introduction. This was a cross-sectional study aiming to test the reliability of a new reactive agility test designed for youth volleyball players to improve both reaction time and hand-eye coordination.

Material and methods. Twenty-four youth volleyball athletes (15 girls and 9 boys) were recruited to participate in this study (age: 11.58 ± 2.20 years old). This study used a FitLight Trainer (FITLIGHT Sport Corp., Ontario, Canada), a wireless system using interconnected light-powered sensors, to measure reaction time and hand-eye coordination. The subjects performed the hand-eye coordination test twice, exactly one week apart, for 30 seconds, with three trials performed for each test. Repeated measures ANOVA was used to test the variation of the six trials performed during the two sessions.

Results. The analysis comparing the sessions revealed significantly longer reaction time in session 1 than in session 2 (mean difference: 47.85 [95% CI: 10.86 to 84.84]; p < 0.012; ES = 0.128). Across the different trials, the greatest single ICC measure (ICC = 0.645) and average ICC measure (ICC = 0.784) were achieved in trial 3. Across the sessions, the greatest single ICC measure (ICC = 0.951) and average ICC measure (ICC = 0.863) were achieved in session 2.

Conclusions. FitLight Trainer is a valid and reliable tool for developing reaction times of youth volleyball athletes.

Authors: Bajuk Studen Katica , Gaberscek Simona , Pirnat Edvard , Zaletel Katja 
Published: May 2021

Abstract

Background
Thyroid nodule diagnosis has become increasingly frequent. Defining optimum surveillance intervals for patients with unsuspicious thyroid nodules remains a challenge. This was a single centre cohort study in which patients diagnosed with unsuspicious thyroid nodules in whom no treatment was indicated were invited for re-evaluation 5 years after the diagnosis. The primary end point of the study was to estimate the change in nodule size with thyroid ultrasound (US) and the secondary end point was to assess the need for clinical management 5 years after the diagnosis.

Patients and methods
Baseline patient parameters and ultrasound characteristics of the nodules were retrospectively collected. At follow-up, thyroid ultrasound was performed.

Results
A hundred and eighteen (107 women / 11 men, aged 56.8 ± 13.4 years) patients were included in the study having 203 nodules at baseline, with mean largest nodule diameter 10.5 ± 7.4 mm. After 5 years, 58 (28.6%) nodules significantly increased in size, 27 (13.3%) decreased, and for 104 (51.2%) of nodules, no change in size was noted. Fourteen (6.9%) nodules disappeared. Additional 26 new nodules (mean largest diameter 7.7 ± 5.0 mm) in 16 patients were identified at follow-up. Regarding the clinical outcome, no new thyroid cancers were found. For 107 (90.7%) patients no further management was indicated. Five (4.2%) patients were referred to thyroidectomy because of the growth of the nodules. Two (1.7%) patients were treated for hyperthyroidism. Four (3.4%) patients did not complete the study.

Conclusions
We report a single centre experience of the natural history of unsuspicious thyroid nodules. Our results showed that 71.4% of such nodules remained stable in size, decreased or even disappeared and that the vast majority of the patients remained clinically stable with no need for treatment 5 years after the diagnosis.
Forward-Looking Model Dedicated to the Study of Electric Vehicle Range Considering Drive Cycles

Published: May 2021

Abstract
This paper deals with the forward-looking model of an electric vehicle (EV). Various simulation tests have been conducted to investigate the effects of the environmental conditions and powertrain design on the EV driving range. The simulation results show the importance of the forward modeling approach in selecting the EV components such as the battery capacity, the power and torque limits of the electric motor, and the impact of this selection on the EV performance during different driving cycles. The simulation results manifest that the forward model is useful when scaling the battery pack to determine the maximum capacity and selecting the suitable motor power and its size. The characteristics of the General Motor EV1 model have been selected in this study to verify the proposed approach.
Comparative evaluation of broth microdilution with E-test, Vitek 2, and disk diffusion for susceptibility testing of colistin on Gram-negative bacteria
Authors: Gupta Parul , Sharma Rajni , Vyas Aruna , Tak Amit 
Published: May 2021

Objectives:
With the increasing threat of multidrug-resistant organisms, colistin has become popular in clinical practice. A better understanding of antimicrobial susceptibility testing methods for colistin is needed for optimal patient management. The aim of the study was to determine the accuracy of E-test, Vitek 2 system for the detection of colistin minimum inhibitory concentrations (MIC) against broth microdilution (BMD).

Material and Methods:
A total of 100 isolates of Gram-negative bacilli were subjected to susceptibility testing for colistin using the following methods: BMD, E-test, Vitek 2, and disk diffusion. Using BMD as the gold standard, comparative analysis between different methods was carried out.

Results:
Comparison of MIC values of E-test (GM = 0.488 mg/ml) against BMD (GM = 0.611 mg/ml using unpaired t-test (t = 2.015, P = 0.045) showed that geometric means of MIC values of E-strip were significantly lower than BMD. Similarly, comparison of MIC values of Vitek 2 system (GM = 0.615 mg/ml) against BMD (GM = 0.611 mg/ml) using unpaired t-test (t = −0.050, P = 0.960) showed no statistical significant differences in geometric means of MIC values. Taking reference as BMD method – the EA for E-strip is 57%, CA is 97%, VME is 2%, and no ME. Similarly, for the Vitek method EA is 64%, CA is 98%, VME is 1%, and ME is 1%.

Conclusion:
Different susceptibility testing methods for colistin show great variation in their results and BMD is the best candidate as gold standard. The Vitek 2 method showed good concordance with BMD.

To the Issue of the Genre Evolution: Passacaglia in the Works of Russian Composers of the Second Half of the 20th Century
Authors: Абдуллина Г.В. 
Published: May 2021

В статье рассматриваются инструментальные сочинения отечественных композиторов второй половины XХ начала XXI века, написанные в жанрах пассакалии и чаконы. Эволюция музыкального языка отражается на их образноэмоциональном содержании, музыкальном материале и формообразовании, что проявляется в новом типе тематизма, способах его развития и в соединении классических структур с элементами современного композиторского мышления. Традиционные жанры, в которых форма в большой степени становится зависимой от драматургии и техник письма, претерпевают существенные изменения.
The article considers the instrumental works by Russian composers of the second half of the 20th beginning of the 21st century, written in the genres of passacaglia and chaconne. The evolution of the musical language at the end of the 20th century has been reflected in their emotional contents, musical material and shaping, which is manifested in a new type of its themes, the ways of its development and the combination of classic structures with new elements of modern composer thinking. Traditional genres, in which form becomes heavily dependent on dramaturgy and writing techniques undergo significant changes.

Music Material Development Techniques (Lectures in «Principles of Music Analysis»)
Authors: Лаул Р.Х. 
Published: May 2021

Настоящий материал продолжает серию публикаций лекций Рейна Лаула по анализу музыки в Санкт-Петербургской (Ленинградской) консерватории. Шестая лекция завершает обзор приемов разработочного развития музыкального материала. В нее вошли шесть из двадцати пяти приемов в авторской классификации (эпизодическая тема, производная тема, варьирование, полифонические варианты, приемы подвижного контрапункта, полифонические структуры), способствующей систематизации разработочных процессов. В поле зрения автора включены неспецифически сонатные способы преобразования музыкального материала, благодаря чему сонатность предстает в гибком и взаимодополняющем взаимодействии с иными принципами формообразования. Особое внимание уделено специфике применения полифонических средств развития музыкального материала в контексте сонатного формообразования. В ходе детального рассмотрения финала симфонии В. А. Моцарта Юпитер оказываются тесно связанными технологический, композиционно-драматургический и стилевой аспекты становления музыкальной формы. Заключительный раздел, обобщающий содержание лекции в целом, содержит пример практического применения предлагаемой автором методологии. Тем самым доказывается ее целесообразность и высокая эффективность как в аспекте анализа интонационной драматургии музыкального произведения, так и в достижении главной аналитической цели в формировании объективного представления о содержательной сути каждого этапа в развёртывании музыкальной композиции.
This material continues the series of publications of R. H. Lauls lectures on music analysis at the Leningrad (Saint Petersburg) Rimsky-Korsakov State Conservatory. The sixth lecture concludes the review of techniques for developing musical material. It discusses six of the twenty-five techniques in the authors classification (episodic theme, derived theme, variation, polyphonic variants, mobile counterpoint techniques, polyphonic structures), which contributes to systematization of the development processes. The authors field of view includes non-specific Sonata methods of transforming the musical material, so that sonateness appears in a flexible and complementary interaction with other principles of formation. Special attention is paid to the specifics of using polyphonic means of developing musical material in the context of Sonata formation. The detailed examination of the finale of Mozarts Symphony Jupiter, shows that technological, compositional, dramatic, and stylistic aspects of the formation of a musical form appear to be closely related. The final section summarizing the content of the lecture as a whole contains an example of practical application of the methodology proposed by the author, proving its expediency and high efficiency not only in the aspect of analyzing the intonation drama of a musical work, but also of achieving the main analytical goal to form a reasoned judgment about the content of each stage in the deployment of a musical composition.

Versions of the Lyrical Song “Lad’s Dream” in the Folklore Traditions of Russia: Historical and Typological Assessment
Authors: Иванова М.Н. 
Published: May 2021

В статье представлен опыт историко-типологической оценки вариантов песен с сюжетом «Сон-предзнаменование несчастливой судьбы (солдатства / гибели) молодца», относящихся к различным региональным традициям. Приводятся результаты сравнительного исследования более ста образцов. Выделены три основных очага распространения песен с исследуемым сюжетом: Русский Север (Архангельская, Вологодская области, Республика Коми), западные области России (Смоленская, Тверская) и южные регионы проживания казаков (Ростовская, Волгоградская области, Ставропольский, Краснодарский края, Чеченская Республика и Республика Ингушетия). Отдельные примеры напевов и текстов также обнаружены в Оренбургской, Челябинской, Псковской, Ульяновской и Кировской областях. В ходе исследования было выявлено три версии развития сюжета и более десяти различных в типологическом отношении напевов. Это объясняется спецификой певческих традиций, к которым принадлежат рассматриваемые образцы. На процесс изменения текстов и напевов оказывают влияние исторические обстоятельства бытования песен, а также индивидуальные особенности исполнительского стиля отдельных певцов. Из множества песен с единым сюжетом может быть выстроена условная историческая цепочка — от наиболее ранних напевов и текстов к вариантам, вобравшим в себя черты позднейшего поэтического и музыкального стиля. При этом выявляется принцип несинхронного развития компонентов художественной формы. Учитываются все формообразующие признаки — структура и содержание поэтического текста, особенности композиционно-ритмической и мелодической организации напевов.
The article presents the experience of historical and typological evaluation of versions of songs with the subject “Dream-omen of lad’s misfortune (recruitment in soldiers / death in a foreign land)”, belonging to various regional traditions. The results of the comparative study of more than one hundred sample songs are given in the article. Songs are recorded in the territory of the Russian North (Archangelsk, Vologda region, Komi Republic), in western regions of Russia (Smolensk, Tver region) and areas of residence of Cossacks (Rostov, Volgograd, Stavropol, Krasnodar Territory, Chechen Republic, Ingushetia Republic). The study revealed three versions of the plot and more than ten typologically different melodies. This diversity is due to the specifics of the singing traditions to which the song variants belong. The process of changing lyrics and melodies is also influenced by the historical circumstances of song distribution, as well as the individual features of the performance style of individual singers. A conditional historical chain is built on the example of variants of songs with a single story — from the earliest in historical terms samples to variants that have included features of later poetry and musical style. All components of the song form are taken into account. The principle of asynchronous development of the components of the art form is revealed by the study.
