Authors: Кіченок Надія 
Published: February 2022

Анотація. Одним із завдань тренера з тенісу є поступове підвищення ефективності гри юного спортсмена. Для його реалізації застосовують ряд методів і стратегій тренування, що передбачають використання різних засобів загальнопедагогічного, спеціального спортивного та технічного характеру. Мета. Вивчення методичних особливостей сучасної підготовки юних тенісистів. Методи. Аналіз наукової та методичної літератури. Результати. Перспективними методологічними підходами у навчально-тренувальному процесі юних гравців слід вважати оптимізацію фізичної та техніко-тактичної підготовки із застосуванням інтегрального, колового та фітнес-тренування, а також використання сучасних технічних засобів, спрямованих на покращення освоєння спеціальних рухових навичок тенісистів, забезпечення контролю та зворотного зв’язку в тренувальному процесі, а також таких, що доповнюють процес підготовки. Розробка методології тренінгу з тенісу виражається у формі альтернативних стилів тренувань або у використанні нових інструментів та обладнання. У випадку ефективності такі підходи впливають на тренерську практику і можуть покращити тренувальний процес. Проте в плані вдосконалення підготовки юних тенісистів необхідно звертати увагу на нововведення, враховуючи особливості розвитку дитячого організму, формування тенісних навичок та відповідність обраних засобів кінематичному зразку рухової дії.
Ключові слова: юні тенісисти, методика тренування, спортивна підготовка.

Kegiatan pengabdian ini juga bertujuan untuk menilai sejauh mana R. mucronata mampu menjadi akumulator bagi logam berat di perairan. Sampel diambil di kawasan pesisir Belawan pada 6 stasiun transek menggunakan jalur tegak lurus. Kandungan logam berat Cu dan Pb pada sampel dianalisis di Laboratorium Penelitian Fakultas Farmasi Universitas Sumatera Utara dengan metode Atomic Arbsorbsion Spectrophotometer (AAS). Dari penelitian yang telah dilakukan didapatkan hasil kandungan Cu dan Pb pada daun, akar, kulit batang R. mucronata. Mangrove jenis R. mucronata ini juga mempunyai kemampuan dalam mengakumulasi logam berat di Pesisir Belawan. Kemampuan R. mucronata dalam menyerap dan mengumpulkan logam berat Cu di dalam tubuhnya adalah dalam kategori sedang dengan nilai 642.396. Sedangkan untuk logam Pb, R. mucronata mampu menyerap dan mengumpulkan logam dengan kemampuan yang rendah dengan nilai 245.328.

Introducción. La utilización de las Tecnologías de la Información y la Comunicación ha impactado positivamente en las diferentes esferas. Objetivo. Determinar la incidencia de la utilización de las Tecnologías de la Información y la Comunicación en la transformación de la Metodología de la Investigación Científica en el contexto de la Educación Superior. Metodología. Se utilizó una metodología descriptiva, basada en la Revisión Sistemática de la Literatura, apoyada en métodos teóricos y en la revisión documental mediante el establecimiento de criterios de búsqueda referenciales. Resultados. 1.Se evidencia que las TICs constituyen herramientas capaces de optimizar significativamente la calidad de la Metodología de la Investigación en el contexto de la Educación Superior, su empleo permite conseguir en menor tiempo y con la calidad requerida los objetivos planteados, creando espacios para el intercambio y la generación de soluciones. 2. Se demuestra que el desafío de la investigación en la universidad radica en el rol del docente que imparte la asignatura de Metodología de la Investigación, quien deberá tener las competencias que le permitan realizar una labor tutorial que congregue los saberes: teóricos, prácticos y pedagógicos y la interacción entre los investigadores. 3. Se sustenta que la información que brindan las técnicas cualitativas, utilizando las herramientas TICs, presentan tanta validez como las que aportan las técnicas cuantitativas. 4. Existe el riesgo por el investigador de enfocar su atención en el uso de las herramientas tecnológicas por encima del análisis metodológico de la investigación. Conclusiones. Se determina la alta incidencia de las Tecnologías de la Información y Comunicación en la transformación de la Metodología de la Investigación Científica en el contexto de la Educación Superior, su empleo constituye una revolución digital y metodológica en las investigaciones, sin embargo, su uso indiscriminado puede traer riesgos que deben ser controlados y evitados de forma permanente.

Authors: Hoque Ashabul , Malek Abdul , Asif Zaman KM Rukhsad 
Published: January 2022

Background: The situation of Covid-19 in Bangladesh is analysed using a mathematical model.
Objective: The objective of this study was the mathematical analysis and statistics of Covid-19 in Bangladesh which originates with reliable and perfect forecasts of the outbreak.
Methodology: The Runge- Kutta method was applied to calculate the variables of the system of equations of the SEIRD compartmental model which was developed based on the SEIR model. Data of Covid-19 pandemic in Bangladesh were analyzed from March 08 to December 07, 2020.
Results: The cumulative infection rate was used in the model to obtain the best fit with the available data. The statistics of Covid-19 in Bangladesh showed that the highest numbers of infections and deaths were observed in the 4th month (end of June) from the reported date those were consistent with other countries. We had also derived a reproduction number, Rt for each day so that the model’s result closely replicates the daily number of recently infected cases. Furthermore, the infected and death rate were observed highest among the age group of 31-40 and 61-above, respectively.
Conclusion: This study contributes to a better understanding about the control policies of the Covid-19 pandemic in Bangladesh based on the estimated parameters of the proposed model and investigations of corona statistics.

Authors: Septianto Arif 
Published: January 2022

Penggunaan drone dalam teknik astofotografi menjadi solusi atas permasalahan pengukuran kecerlangan langit untuk mengetahui hilangnya waktu syafaq mengunakan SQM yang dinilai kurang efisien. Pada kasus menentukan awal waktu isya ditandai dengan hilangnya mega merah (syafaq) pada langit sebelah barat saat malam hari. Dalam peneitian pengukuran citra langit peneliti menggunakan teknologi drone sebagai sensor image. Data foto yang diambil pada penelitian ini diambil dalam rentang 15 sekon/ capture. Data yang didapat tidak dapat langsung di gunakan karna masih terdpat noise. Karnanya perlu dihilangkan terlebih dahulu dengan metode image processing agar data tersebut dapat terlihat jelas dan mudah direpresentasikan oleh mata manusia atau komputer yang sifatnya deterministik. Metode pengolahan data pada penelitian ini menggunakan Microsoft excel dan MATLAB dengan persamaan polynomial 5 untuk memplot grafik kecerahan langit. Hasil pada penelitian ini menunjukan bahwa waktu hilangnya syafaq berbeda- beda pada setiap harinya. Waktu paling awal hilangnya syafaq terjadi pada pukul 18:38:18 dan waktu paling akhir terjadi pada pukul 18:59:19
Fluorine in the mudvolcano waters of the Kerch-Taman region
Authors: Savenko A. V. , Bychkov A. Yu. , Poltavskaya S. V. , Savenko V. S. 
Published: January 2022

Content of dissolved fluorides in the waters of 13 mud volcanoes of the Kerch-Taman region was determined: 0,13–2,00 mg/l with average value of 0,87 mg/l (n = 37). A fairly close correlation was established between the fluorine concentration and pH value (r = 0.80) in the absence of correlation with mineralization and content of components of the basic salt composition. It was suggested that the fluorine concentration in mud-volcano waters is controlled by the exchange reaction where et is content of adsorbed and structural fluorine (hydroxyl ions) in the clay minerals; F– et OH– is concentration of fluorides (hydroxyl ions) in the aqueous phase.
