Published: September 2023

Tujuan penelitian ini adalah mengkaji cara melakukan interpolasi dua dimensi untuk menentukan nilai tabel sebaran F, membuat  program interpolasi dua dimensi berbantuan Matlab, dan mengkaji perbandingan dari metode-metode yang digunakan (manual maupun berbantuan program). Jenis penelitian ini adalah penelitian dasar dengan pendekatan studi literatur. Karena itu keseluruhan data penelitian diambil dari buku-buku dan referensi lain yang relevan dengan masalah yang dikaji. Adapun hasil penelitian adalah sebagai berikut: pertama, interpolasi dua dimensi dalam tabel nilai kritik sebaran F dapat dilakukan dengan menggunakan prosedur interpolasi satu variabel secara berurutan. Formula interpolasi dua dimensi dapat dibuat dengan mengacu pada bentuk umum polinom interpolasi Lagrange dan Newton. Kedua, telah dibuat suatu program interpolasi dua dimensi berbantuan Matlab yaitu program yang dapat menentukan nilai tengahan suatu fungsi dalam dua variabel dengan menggunakan formula interpolasi polynomial Lagrange dan formula interpolasi polynomial Newton. Ketiga, dilihat dari hasil akhir, tidak ada perbedaan yang ditunjukkan oleh kedua metode yang digunakan. Dilihat dari proses, interpolasi dua dimensi dengan menggunakan metode interpolasi polynomial Lagrange memiliki kelebihan dalam kesederhanaan pembuatan program, namun memerlukan waktu yang cukup lama dalam penyelesaian manualnya. Sedangkan metode interpolasi polynomial Newton memiliki kelebihan dalam kesederhanaan proses kerja secara manual, namun memerlukan waktu yang cukup lama dalam pembuatan program

Problem Posing: Strategi yang Memfasilitasi Keterampilan Berpikir Tingkat Tinggi Matematika Siswa
Authors: Blegur Irna Karlina Sensiana
Published: September 2023

Pengembangan kemampuan berpikir tingkat tinggi (HOTS) siswa merupakan salah satu tujuan utama dalam pembelajaran matematika. Belajar melalui pemecahan masalah merupakan kunci utama kemampuan ini dapat dikembangkan. Pemecahan masalah sendiri dapat diartikan sebagai kegiatan untuk memecahkan masalah yang kompleks yaitu masalah yang tidak memiliki solusi otomatis namun membutuhkan penalaran untuk memecahkannya. Umumnya masalah seperti ini diberikan oleh guru saat pembelajaran, lalu meminta siswa menyelesaikannya, dengan harapan siswa akan belajar dan pengembangan HOTS terjadi saat memecahkan masalah tersebut. Di sisi lain belajar memecahkan masalah juga dapat dilakukan pada masalah yang dimunculkan (pose) oleh siswa itu sendiri atau dikenal dengan problem posing. Strategi ini mengarahkan siswa untuk membuat masalah baru atau memformulasi ulang masalah berdasarkan masalah atau informasi yang diberikan lalu menyelesaikannya. Artikel ini bertujuan untuk membahas mengenai strategi problem posing dan contoh desain masalah dengan menggunakan strategi ini dalam pembelajaran kalkulus integral. Lebih lanjut, terkait bagaimana strategi problem posing dapat memfasilitasi HOTS matematika siswa selama pembelajaran juga dibahas dalam artikel ini
Modelos de predicción avanzados para el cálculo de reservas en la industria aseguradora
Authors:   , Aguirre Alejandro
Published: September 2023

La industria del seguro tiene una necesidad urgente de innovación luego del arribo del concepto de “Insurtech”, que propone un mercado más competitivo basado en la innovación y en la aplicación de tecnología al negocio (Alarcon, 2018). Pero por otro lado se trata de una actividad muy regulada por los organismos gubernamentales, que establecen un marco común de aplicación de procedimientos y técnicas que las aseguradoras deben respetar. En esa puja entre innovación y regulación, está el concepto de las Reservas, que representan la provisión económica que las empresas aseguradoras deben disponer para hacer frente al pago de los posibles siniestros que podrían ocurrir en el futuro, como consecuencia directa de las coberturas que les brindan a sus asegurados (NietoDeAlba, 1964). Si bien se trata de un tema definido por ley, representa uno de los indicadores más importantes a tener en cuenta en la toma de decisiones porque establece el límite de la libre disponibilidad de fondos que la compañía puede invertir para obtener resultados financieros (LopezBriega, 2016). No preocupa tanto si en un período un rubro o producto ofrecido por una aseguradora es deficitario si se tiene en cuenta sus resultados técnicos, porque la ganancia se puede generar a partir de los resultados financieros producto de invertir el dinero en el tiempo transcurrido entre que se cobra el seguro y se paga el siniestro. En esa actividad cuando mejor sea la predicción de las reservas, mayor será la renta financiera obtenida de las disponibilidades monetarias, mayor será el ahorro de costos directos, y se tendrían más oportunidades en la aplicación de precios personalizados que permitan capturar clientes. El objetivo general de éste trabajo es analizar el funcionamiento de diferentes modelos de predicción avanzados, basados en técnicas de Machine Learning, que puedan estimar las reservas futuras con antelación a la ejecución de los tradicionales procedimientos de cálculo usados en la industria de acuerdo a lo definido por la ley.

The temperature-dependent resistivity of heavily Al- and N-codoped 4H-SiC grown by physical vapor transport (PVT) with Al concentrations (C
Al) higher than 1019 cm−3 is investigated to obtain high-growth-rate and low-cost p+-type substrates suitable for the collectors of n-channel insulated-gate bipolar transistors. The resistivity is compared with that of heavily Al-doped 4H-SiC grown by CVD. In the band conduction region, the hole mobility of the PVT-grown codoped samples is slightly lower than that of the CVD-grown sample at the same C
Al. At C
Al values of around 2 × 1020 cm−3, the temperature range in the variable-range-hopping conduction region for the PVT-grown codoped samples is much wider than that for the CVD-grown samples.

The proliferation of online learning platforms has made it increasingly difficult for students to choose a platform that best meets their needs. This study aims to prioritize online learning platforms based on student needs using the Multiple Criteria Decision Analysis (MCDA) Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The criteria used in the analysis were ease of use, variety of courses, cost, and reputation of instructors. The results of the analysis indicate that edX is the most suitable online learning platform for students based on the criteria and weights used in the study. Coursera, Udemy, and LinkedIn Learning were also evaluated in the analysis and may be suitable for students with specific priorities or preferences. The MCDA TOPSIS method provides a transparent and objective approach to evaluating the alternatives and offers insights into the strengths and weaknesses of each platform. The results of this study can help students make more informed decisions and choose a platform that best meets their individual needs. However, the choice of criteria and weights may vary depending on the preferences and priorities of different students, and the results should be interpreted accordingly

The concept of E-Learning itself is a guide between learning processes that are packaged in the form of information technology. During the pandemic, schools in Indonesia began to make changes to offline learning to online by utilizing various applications such as the Google Classroom and WhatsApp applications. Based on these conditions, the researcher tried to develop a system for use in schools in the form of Android-based e-learning using the waterfall method. Based on the results of system design and testing it appears that this system can be used at research locations because the system can run well based on the results of black box testing, while the expert judgment of 10 people said it was very good, while the user response was 150 people with a very good response of 70 percent (105 people), good 30 percent (45 people). So that by using an Android-based E-Learning application, of course learning done in schools is better than those that only use conventional models or only use Whatsapp or Google Classroom. In addition, with E-Learning the learning process that is usually carried out in schools can be done without having to go to school again, students and teachers can carry out the learning process from their respective homes using smartphones and the internet.

Citizens' policy perception, policy measures, and trust in political institutions after the first wave of COVID-19
Authors: Vincenzo Memoli
Published: September 2023

Crises bring both human consequences and political repercussions. COVID-19, like any other crisis, strained both European governments and public support for them. During the first wave of the pandemic, political trust was correlated with public adherence to infection containment measures in the major democracies. At the end of the first wave, how did public perceptions of COVID-19 measures and of measures introduced by institutions to protect health and the economy affect the bond of political trust between the governed and the governors? Using Eurobarometer data, we estimate the effects on political trust of the public’s assessment of institutional performance, political output and policy. Applying various multilevel regression models, we show that, at the end of the first wave of the pandemic, political trust was positively affected by institutional performance and only partially affected public perceptions and the policy measures taken by governments to contain the spread of the virus.

Этиология лимфаденопатий у детей может быть различна: это вирусные инфекции, аутоиммунные заболевания, метастатические поражения лимфатических узлов, иммунодефицитные состояния, онкологические заболевания. Основной проблемой диагностики лимфаденопатий состоит в сходстве их клинических картин. При выявлении каких-либо изменений в лимфатических узлах, чаще всего предполагают онкологическое заболевание, что приводит к запоздалой диагностики основного заболевания, в том числе туберкулеза. Одной из форм внелегочного туберкулеза является туберкулез периферических лимфатических узлов (ТПЛУ). ТПЛУ – опухолевидное, чаще генерализованное поражение нескольких групп лимфатических узлов с развитием в них специфического воспалительного процесса.Данная форма туберкулеза возникает при снижении общего иммунитета, а также изменении реактивности организма у детей при первичном туберкулезе. Лимфатические узлы при ТПЛУ чаще подвижные, неспаянные с окружающими тканями, безболезненные при пальпации, кожа над ними не изменена. Отсутствие микобактерий туберкулеза (МБТ) в биопсийном материале не исключает диагноз туберкулез, поэтому нужно стремиться к верификации диагноза с помощью гистологического исследования.Наиболее результативным методом получения материала из пораженного ЛУ является тонкоигольная биопсия. В биоптате обнаруживают эпителиоидные гранулемы, клетки Пирогова–Лангханса, некроз, микобактерии туберкулеза редко

The etiology of lymphadenopathy in children can be of various origin: these are viral infections, autoimmune diseases, metastatic lesions of the lymph nodes, immunodeficiencies, and oncological diseases. The main challenge in diagnosing lymphadenopathies is similarity of their clinical manifestations. If any pathological signs in the lymph nodes are detected, it is oncopathology that most often suspected; this results in a delayed diagnosis of the underlying disease, including tuberculosis. Peripheral lymph node tuberculosis (PLNTB) is the commonest form of extra-pulmonary tuberculosis (EPTB). PLNTB is a tumor-like, often generalized lesion of several groups of lymph nodes accompanied by a specific inflammatory process in them. This form of tuberculosis occurs with a decreased general immunity and changes in the body reactivity, more often in children with primary tuberculosis. Lymph nodes in PLNTB are often freely movable, painless, the skin over lymph nodes is not changed. The absence of Mycobacterium tuberculosis (MBT) in the biopsy material does not exclude the diagnosis, therefore, it is necessary to evidence the diagnosis using histological examination. The most effective approach to obtain sample from the affected lymph nodes is a fine needle aspiration biopsy. The biopsy findings reveal epithelioid cell granulomas, Pirogov-Langhans cells, necrosis; Mycobacteria tuberculosis are rare

Для того чтобы оценить современное развитие в эпидемиологии и хирургические способы коррекции инфекционного эндокардита исследованы и проанализированы демографические и клинические данные 726 заболевших, которые проходили стационарное лечение в течение предыдущих двадцати пяти лет. Стоит отметить, что с 2005–2017 гг. по сравнению с 1993–2004 гг. обнаружен значительный прирост числа пациентов, увеличение среднего возраста и преобладание женского пола среди больных. В ходе работы было проведено сравнение двух групп и выявлено, что встречаемость внутривенных наркоманов среди всех заболевших инфекционным эндокардитом существенно не увеличилась. Обнаружено преобладание первичного инфекционного эндокардита, развивающегося на интактных клапанах, по сравнению с вторичным, который возникает уже на поврежденных клапанах. Заметно чаще проводилась коррекция клапана при условии искусственного кровообращения у пациентов с одновременным поражением митрального и аортального клапанов. Однако, уменьшилось количество не только случаев раннего протезного эндокардита, но и что не мало важно, выявлен спад внутрибольничной летальности. Чаще проводили неотложные вмешательства при перивальвулярных поражениях, а также производили клапаносохраняющие оперативные вмешательства и значительно чаще применяли биопротезы

Caracterización de reflectancia espectral y concentración de SST en cuerpos de agua continental a nivel mundial
Authors: Cruz Retana Alejandro
Published: September 2023

La medición de Parámetro de Calidad del Agua (PCA) asociado con los Sólidos Suspendidos Totales (SST) en laboratorio considera todas las variables biofísicas que intervienen en el cuerpo de agua estudiado. A nivel de modelos de regresión para la estimación de SST a través de reflectancia (base en imágenes satelitales) las características biofísicas son incluidas implícitamente en las estadísticas del modelo. Sin embargo, pocos son los estudios que consideren modelos conjuntos para diferentes cuerpos de agua. Por lo tanto, el presente estudio es orientado a la relación de la dispersión tanto de las reflectancias, como las concentraciones de SST para caracterizar cuerpos de agua bajo diferentes condiciones.

Este estudio se basa en 48 cuerpos de agua distribuidos en los 5 continentes en el mundo (intervalo de 0 a 60°Latitud). Dichos cuerpos de agua corresponden a ríos, lagos, lagunas y presas de diferente tamaño. Los cuerpos de agua fueron estudiados bajo diferentes condiciones de la estacionalidad y la latitud. Este estudio se realizó con base en medidas de dispersión y tendencia central a fin de conocer el comportamiento de los datos. En este sentido, el presente estudio tiene por objetivo identificar similitudes y diferencias en la estimación de SST por medio de reflectancias. Las reflectancias utilizadas en este estudio fueron extraídas de los productos Sentinel 2A y Landsat 8 OLI descargados de Copernicus y Earth Explorer. La selección de los modelos se realizó con base en el coeficiente de determinación (R2). Raíz del Error Cuadrático Medio (RMSE), Sesgo (BIAS), E (eficiencia de Nash-Sutcliffe). Los resultados analíticos del presente estudio se enfocan en la Banda 4,5 y 6 del sensor Landsat y su comparativo proporcional con Sentinel (B8A=B5 y B11=B6 caso de sentinel). A partir de ello se identificaron 8 CA que presentan mayor diferencia en reflectancia sin embargo el resto de los cuerpos de agua (CA) las reflectancias presentan una varianza menor.

Spectral-Domain Modelling of Wave Energy Converters as an Efficient Tool for Adjustment of PTO Model Parameters
Authors: Tan Jian , Jarquin  Laguna Antonio
Published: September 2023

The power take-off (PTO) system is a core component in WECs as it plays a critical role in power production. In numerical models the PTO systems are commonly represented and simplified through a combination of linear stiffness and damping terms in the equations of motion. These parameters are influential to the dynamic response and thus affect the power performance of WECs. In the preliminary design and optimization of WECs, proper tuning of the PTO damping and stiffness could reflect better the potential of the concept. In practice, the PTO damping and stiffness are tuned to maximize the absorbed power by achieving the desired velocity amplitude or phase of the velocity with respect to the excitation force. However, recent literature has indicated that the selection of PTO parameters for maximum mechanical power absorption is not necessarily optimal for the maximum production of electrical power when the conversion efficiency of the electrical machine is included. To obtain these parameters which maximize the delivered electrical power, wave-to-wire models are widely used. Nevertheless, wave-to-wire models are predominately established by using time-domain models which can be associated with large computational efforts from the perspective of early-stage design and concept evaluation. To tackle this challenge, a spectral-domain-based wave-to-wire model is proposed to cover both hydrodynamic and electrical responses. In this paper, a spherical heaving point absorber integrated with a linear permanent-magnet generator is used as reference. The relevant nonlinear effects are incorporated by statistical linearization using spectral-domain modelling. In particular, the nonlinear effects considered in this work include the viscous drag force, the electrical current saturation and the partial overlap between the translator and stator components of the linear generator. The model results are then verified against a nonlinear time-domain-based wave-to-wire model. Subsequently, the proposed model is applied to identify the PTO parameters for maximizing the electrical power in various wave states. The computational efficiency and accuracy of the proposed spectral-domain model are compared with the time-domain model, with regard to the identification of the proper PTO damping and stiffness. Based on the results, the advantage of using the spectral-domain-based wave-to-wire modeling in PTO tuning is demonstrated.

Quality of teaching in Secondary Schools in Borongan City Division: Response to Globalization SY 2022-2023 on performance status of the Secondary Public Schools as input to Teaching Development Program. Out of 57 respondents were distributed into two groups namely one (1) administrator principal/school head and fifty-six (56) teachers of the quality of teaching in Maypangdan National High School, Division of Borongan City. Descriptive research was used to conduct a survey investigation, description will be used for frequencies, averages, and other statistical calculations. The respondents are very satisfactory as to how seriously important the job performance appraisals prefer more autonomy in their work instead of being closely supervised, and job-focused rather than family-focused, they want their job to be challenging. The correlation of -0.19 shows a very weak negative correlation between the two, since -0.19, is very close to zero, it is safe to say that there is almost no correlation between the two, there is no significant relationship. The results show that whatever generation the respondents are in, they agree with the Quality of Teaching in the Secondary Schools in Borongan City Division: Response to Globalization, leadership program by coaching teacher-trainees, accountability, communication, and change management. The finding shows a deep level of respect the teachers regardless of their length of tenure and years of teaching experience. Teachers are the assets of the school and they should be given enough leeway and freedom to do their jobs for more creativity, innovation, and respect for each other work.

Published: September 2023

Background: Transdermal medication administration seems promising, but it is a difficult method to implement for both local and systemic drug effects.

Objective: The goal of this study was to create a nanogel with a smaller particle size in order to increase the bioavailability of Curcumin, an anti-inflammatory and anti- psoriasis medication.

Methods:The goal of this research is to create nanosize Curcumin dispersion using an emulsion-solvent diffusion technique with the addition of a gelling agent to create a nanogel. Particle sizes in the formulation range from 100 to 400 nanometers. Curcumin is a medication that is used to treat psoriasis and chronic inflammatory disorders.

Results: The glycerol:waterco-solvent system was chosen for the preparation of curcumin nanogels with various polymers because it has a higher permeability coefficient than the alcohol:water co-solvent system. In a franz diffusion cell, permeation across cellophane membrane was achieved using 0.9 percent w/v sodium chloride as the receptor fluid. Curcumin-containing gels with eudragit polymer had a higher permeability coefficient.

Conclusion: In compared to nanogels made with HPMC and methyl cellulose, curcumin nanogels produced with carbopol with permeation enhancer showed greater flux improvement. Curcumin nanogels with carbopol 940 as a gelling agent and Eudragit S-100 as a permeation enhancer.
