Authors: Corella Parra Luis Manuel , Olea Miranda Jaime
Published: January 2023

La globalización ha eliminado brechas comerciales que limitaban las relaciones internacionales, uno de los fundamentos de la economía moderna que impulso el desarrollo de miles de negocios; el problema, la saturación del mercado donde se ofrecen los mismos servicios o bienes, dejando a la deriva empresas que no pueden adaptarse a la variabilidad en la demanda u ofrecer ese valor añadido o singular que marca la diferencia de la competencia.
El presente proyecto se desarrolla en una empresa comercializadora de productos para riego en la zona noroeste del estado de Sonora. La problemática es la presencia de problemas de organización en almacén, lo que se traduce en tiempos excesivos en atención y servicio al cliente, agotamiento, sobre inventario, perdida de productos y registros conflictivos. Mediante la implementación de varios elementos de control y gestión, se desarrolla un sistema de control de inventario, capaz de mejorar el flujo de materiales en almacén y llevar registros precisos y confiables al enlazar herramientas físicas y digitales, la implementación de estas acciones de mejora, se expresan en el incremento significativo de la satisfacción del cliente al proveer el producto correcto en tiempo y forma. La metodología e implementación presentan la importancia de cada elemento dentro del sistema, la dependencia entre estos y la capacidad de adaptarse a las necesidades y limitantes de la empresa. Estos métodos, técnicas u herramientas utilizadas son de uso común en el campo de la ingeniería industrial, lo cual habilita una sencilla integración y entendimiento en empresas con poca experiencia en el tema.
Redescripción de Haliotrematoides mediohamides (Monogenea: Dactylogyridae), un parásito branquial del sargo Calamus brachysomus (Perciformes: Sparidae) del océano Pacífico oriental
Authors: Cruces Celso Luis , Chero Jhon Darly , Sáez Gloria , Luque José Luis
Published: January 2023

The monogenean Haliotrematoides mediohamides Kritsky & Mendoza-Franco, 2009 (Monogenea: Dactylogyridae) is redescribed based on examination of the type specimen (paratypes) and newly collected specimens parasitizing the gills of the Pacific porgy, Calamus brachysomus (Lockington, 1880) (Perciformes: Sparidae) (type host), a neritic fish captured off the coastal zone of Puerto Pizarro, Tumbes, Peru. Even though this monogenean was described 12 years ago, that description did not report some of the unique morphological features of H. mediohamides and neither did it offer a whole-mount drawing of this species. The most important characteristics of H. mediohamides are: 1) a male copulatory organ with hook-shaped distal end, 2) a non-coiled vaginal duct, 3) numerous secretory gland-cells associated with the peduncle, 4) a chandelier-shaped extrinsic adductor muscles articulated with superficial roots of the anchors, 5) a single tadpole-shaped prostatic reservoir, and 6) a vas deferens anteriorly convoluted. In addition, the first whole-mount drawing of H. mediohamides, as well as morphometric data are provided. Haliotrematoides mediohamides represents the first record of Haliotrematoides in South America. Haliotrematoides mediohamides is the third dactylogyrid species recorded to infect C. brachysomus in Peru.

Published: January 2023

Reef fish species richness of the Veracruz Reef System National Park (VRSNP) in the SW Gulf of Mexico is well known. However, the knowledge of the assemblage structure and its spatial variability in the reef ecosystem is quite limited. For that purpose, 5 field surveys (2012-2015) were performed, using the stationary visual census method, at 10 selected reefs. The most important findings were: 116 reef species were recorded. Average total reef fish density (2.31 Ind/m2) is similar to the records for the Caribbean reefs in the 20th century. The top 5 most abundant species were: Chromis multilineata, Ocyurus chrysurus, Abudefduf saxatilis, Stegastes leucostictus, and Elacatinus jarocho. We found evidence of a spatial distribution pattern with 3 well-defined groups of reefs: (1) those near the city of Veracruz, (2) those near the outlet of the Jamapa River, and (3) those farther from the city. Higher fish densities are associated to both high hermatypic coral and low crustose coralline algae bottom covers. The assemblage structure of reef fishes is different at distinct geomorphological reef zones. As expected, with some differences in the species abundance order, the assemblage structure of reef fishes is similar at all coral reefs in the Gulf of Mexico.

Abstract: People communicate using sign language by visually conveying sign patterns to portray purpose. One method of communicating with deaf-mute people is to use sign language mechanisms. One of the nonverbal communication strategies used in sign language is the hand gesture. Many manufacturers all over the world have created various sign language systems, but they are neither adaptable nor cost-effective for end users. We present a design that can recognize various American sign language static hand motions in real-time using transfer learning, Python, and OpenCV in this paper. “Hello, Yes, No, Thank You, and I Love You" are all prevalent sign language terms that our system correctly acknowledges. The following are the key steps in system design; we created our own dataset taking prominent gestures of the American Sign Language, captured images with OpenCV and webcam, the images were then labelled for object detection, training and testing of dataset was done with transfer learning using SSD MobileNet, and eventually the gestures were successfully determined in real-time.

A redemocratização brasileira entre a Corte Interamericana de Direitos Humanos e o Supremo Tribunal Federal
Authors: Pires Matheus Conde , Santos Beatriz Tavares Fernandes dos
Published: January 2023

Neste artigo, foram abordadas as decisões proferidas pelo Supremo Tribunal Federal - STF na ADPF nº 153/DF e pela Corte Interamericana de Direitos Humanos – CIDH no caso Gomes Lund e outros vs. Brasil pela perspectiva da tensão entre as tradições do constitucionalismo e da democracia. Observou-se que, no primeiro caso, o STF fixou o entendimento de que o art. 1º, § 1º, da Lei de Anistia (nº 6.683/79), que concedeu anistia a todos que cometeram crimes políticos ou conexo com estes no período de 02/09/1961 a 15/08/1979, foi recepcionada pela CF/88, enquanto no segundo a CIDH estabeleceu que os preceitos da Lei de Anistia impedem a investigação de graves violações de direitos humanos, e, por essa razão, são incompatíveis com a Convenção Americana. Verificou-se que, ao definir a Lei Fundamental o povo exerce sua soberania de forma indireta, através de instituições, enquanto ao elaborar um tratado internacional as restrições de participação popular ativa são mais enfáticas. Ademais, convenções internacionais indicam limitações ao espaço político, retirando de deliberação questões que ofendam os direitos humanos. Por meio do método de estudo de caso, com revisão bibliográfica e documental, concluiu-se que essas questões podem ajudar a compreender os motivos pelos quais a sentença proferida no caso Gomes Lund e outros vs. Brasil não foi devidamente implementada pelo país. Além disso, o estudo desenvolvido indica que, para se alcançar a efetivação dos direitos humanos, faz-se necessário, antes, percorrer um caminho político.

RISCO-PAÍS E CICLOS ECONÔMICOS BRASILEIROS PÓS-REGIME DE METAS PARA A INFLAÇÃO
Authors: Borges Wesley Augusto de Freitas , Bragagnolo Cassiano
Published: January 2023

Este trabalho busca analisar o impacto do choque de risco-país sobre os ciclos econômicos brasileiros pós-regime de metas de inflação. Para tanto, utiliza-se um modelo real business cycle (RBC) de small open economy (SOE) de Schmitt-Grohé eUribe (2003) modificado para estimar parâmetros por meio de métodos bayesianos. Os resultados obtidos sugerem que o choque de risco-país explica majoritariamente as oscilações de curto prazo da dívida externa e do investimento e pequena parte das oscilações de curto prazo do estoque de capital, enquanto as oscilações de curto prazo das demais variáveis são explicadas pelo choque de produtividade. Além disso, um choque positivo no risco-país ou possível downgrade por uma agência classificadora de risco geraria maior impacto sobre os investimentos e a dívida externa nacional. Entretanto, há um trade-off importante entre a possível perda de autonomia e soberania nacional por parte da autoridade monetária quando se adéqua às recomendações de agências avaliadoras ou supranacionais que necessita maior investigação.

Published: January 2023

Analisam-se, no artigo, indicadores socioeconômicos sobre os oito países membros da União Econômica e Monetária da África Ocidental (Uemoa), assim como as relações comerciais internas antes e após a criação desse bloco, destacando-se asituação da Guiné-Bissau, último país a entrar e um dos mais pobres do mundo. Exploram-se os dados com técnicas de estatísticas descritivas para examinar a performance econômica e comercial do bloco como um todo e também a posição dos países individualmente. Percebe-se que, após a criação da Uemoa, os indicadores socioeconômicos mostraram evolução e as trocas comerciais entre os membros ganharam em intensidade. A comparação do desempenho econômico permite constatar que, na maioria dos indicadores analisados, a Guiné-Bissau mostra-se bastante frágil, tendo evoluído pouco após a sua incorporação. Por razões de cunho também histórico e estrutural, o país permanece em clara desvantagem em relação aos demais, o que permite indagar sobre os reais benefícios da sua participação nesse processo de integração.

Published: January 2023

Parte das questões associadas à dificuldade de aprendizagem da matemática está ligada a fatores externos ao indivíduo aprendente. O objetivo desta pesquisa foi acessar as memórias de professores dos anos iniciais e identificar a percepção sobre fatores de risco que provocaram as dificuldades de aprendizagem em matemática na época em que eram estudantes. Para tanto, foram observados os métodos de ensino, a formação e conduta do professor, a relação com a matemática e a história afetiva pessoal e escolar rememorados pelos sujeitos da pesquisa. Dentro de uma abordagem qualitativa aplicamos um questionário a 45 professores dos anos iniciais da rede de ensino público municipal em Jequié. A partir dos depoimentos dos professores, que declaram ter um histórico de dificuldade em matemática durante sua trajetória de estudantes, foram analisados os dados que apontaram que as dificuldades em matemática atribuídas pelos participantes se referem aos métodos de ensino, a incongruência e desconformidade da matemática escolar com o cotidiano, à falta de apoio e de apreço pela disciplina como resultado de construções culturais estereotipadas da matemática, dentre outras causas.
An experimental analysis on spectrum absorption characteristics of high-temperature material based on nanostructure
Authors: Yang Shuhan , Shen Bin , Dai Bin , Liang Haijian
Published: January 2023

High-temperature metal nanostructure endows various potential
applications in optical communication, aerospace and other fields. In
this letter, periodical nanostructure with high-temperature metal is
proposed to enhance spectrum absorption. The absorption characteristics
and mechanism were investigated and analyzed in the range of 360 ∼ 760
nm wavelength based on the finite difference time domain (FDTD) method.
The results indicate that particle shape, material, and period are the
main factors affecting absorption. After optimization, the peak and
average absorption reach 68.6% and 61.32% respectively. The coupling
between surface plasmon polaritons (SPPs) and local surface plasmon
resonance (SPR) enhances the optical properties obviously. The results
have certain reference value for the application of high-temperature
metal nanostructure in special environments.

Deriving spatially explicit direct and indirect interaction networks from animal movement data

Published: January 2023

Quantifying spatiotemporally explicit interactions within animal
populations facilitates the understanding of social structure and its
relationship with ecological processes. Data from animal tracking
technologies (Global Positioning Systems [“GPS”]) can circumvent
longstanding challenges in the estimation of spatiotemporally explicit
interactions, but the discrete nature and coarse temporal resolution of
data mean that ephemeral interactions that occur between consecutive GPS
locations go undetected. Here, we developed a method to quantify
individual and spatial patterns of interaction using continuous-time
movement models (CTMMs) fit to GPS tracking data. We first applied CTMMs
to infer the full movement trajectories at an arbitrarily fine temporal
scale before estimating interactions, thus allowing inference of
interactions occurring between observed GPS locations. Our framework
then infers indirect interactions – individuals occurring at the same
location, but at different times– while allowing the identification of
indirect interactions to vary with ecological context based on CTMM
outputs. We assessed the performance of our new method using simulations
and illustrated its implementation by deriving disease-relevant
interaction networks for two behaviorally differentiated species, wild
pigs (Sus scrofa) that can host African Swine Fever and mule deer
(Odocoileus hemionus) that can host Chronic Wasting Disease. Simulations
showed that interactions derived from observed GPS data can be
substantially underestimated when temporal resolution of movement data
exceeds 30-minute intervals. Empirical application suggested that
underestimation occurred in both interaction rates and their spatial
distributions. CTMM-Interaction method, which can introduce
uncertainties, recovered the majority of true interactions. Our method
leverages advances in movement ecology to quantify fine-scale
spatiotemporal interactions between individuals from lower temporal
resolution GPS data. It can be leveraged to infer dynamic social
networks, transmission potential in disease systems, consumer-resource
interactions, information sharing, and beyond. The method also sets the
stage for future predictive models linking observed spatiotemporal
interaction patterns to environmental drivers.

Traveltime calculations for qP, qSV, and qSH waves in 3D tilted transversely isotropic media using fast sweeping method with a Newton method local solver
Authors: Lu Yongming , Zhang Wei
Published: January 2023

Efficient and accurate traveltime calculations of seismic waves have
important applications in tomography, prestack migration, earthquake
location, etc. Anisotropy significantly affects the traveltimes of
seismic wave. For high-resolution imaging and inversion, it is necessary
to consider anisotropy in the traveltime calculations. The fast sweeping
method (FSM) does not need to track and store the minimum traveltime
point of wavefront, which has important applications in computing the
anisotropic first-arrival traveltime. The conventional method that
solves a transformed traveltime quartic equation combined with FSM is
suitable for general anisotropic media. However, this method involves
finding the intervals of roots and solving the quartic equations using
bisection algorithm at each iteration, leading to high computational
cost and instability for the 3D problems. In our previous work, for the
vertical transversely isotropic (VTI) case, we developed an FSM to
compute the qP-wave first-arrival traveltimes by analytically solving
the simplified quadratic slowness equation in a specific
triangular-pyramid stencil. This method greatly improves the
computational efficiency. However, for the qP and qSV waves,
analytically solving the slowness equation cannot be extended to tilted
transversely isotropic (TTI) media. To address this problem, we
introduced the Newton method in the triangular-pyramid local solver to
quickly solve the TTI slowness equation. For the qSH wave, its slowness
equation is quadratic and simple to solve. The proposed method provides
an efficient procedure for the traveltime calculations of qP, qSV, and
qSH waves in 3D general TTI media. Numerical examples have verified the
efficiency and accuracy of the proposed method.

Published: January 2023

In this work we present a unique set of coincident and collocated high-
resolution observations of surface currents and directional properties
of surface waves collected from an airborne instrument, the Modular
Aerial Sensing System (MASS), collected off the coast of Southern
California. High-resolution observations of near surface current
profiles and shear are obtained using a new instrument, DoppVis, capable
of capturing horizontal spatial current variability down to 128m
resolution. This data set provides a unique opportunity to examine how
currents at scales ranging from 1-100 km modulate bulk (e.g. significant
wave height), directional and spectral properties of surface gravity
waves. Such observations are a step toward developing better
understanding of the underlying physics of submesoscale processes (e.g.
frontogenesis and frontal arrest) and the nature of transitions between
mesoscale and submesoscale dynamics.
Variabilities in Urban Ambient Noise Before, During, and After Covid-19 Lockdown in the Peruvian Capital
Authors: Condori Cristobal , França George Sand , Maciel Susanne , Macedo Orlando , Quispe Lady D. , Hussain Yawar
Published: January 2023

ABSTRACT. Recent studies have shown that urban ambient noise (UAN) decreased at many sites due to a slowdown in human activities brought by the SARS-CoV-2 (COVID-19) pandemic lockdowns. Such understanding is inferred from the historical record of the noise levels, which may also help us disambiguate noise sources as required for ambient noise tomography, microseismic and other seismic based studies. As UAN is site-specific, and its analysis enables passive situational awareness, therefore, in the present study, we analyzed the temporal variations in UAN before, during and after the social isolation in the metropolitan region of Lima, the capital of Peru, for the very first time. We used continuous waveforms recorded from February 1st to August 31st, 2020, at the Ñaña (NNA) broadband seismic station for the analysis. Results show the temporal changes occur in different frequency ranges; for example, at frequencies >1 Hz, significant changes in the mean daytime amplitudes are observed, which are absent in the lower frequency range (0.1–1, 1–3, 3–5 Hz). A maximum noise reduction of 37% is observed and should be considered for any future application of UAN. The results were verified by comparing with Community Mobility Reports (CMR) provided by Google using statistical change-point analysis.
Mechanical properties and flexural behaviour of reinforced concrete beams containing recycled concrete aggregate
Authors: DAWOOD Malak H. , Al-ASADI Ali K.
Published: January 2023

Increasing waste recycling has become an essential process in the construction industry due to the environmental and economic advantages, such as minimizing waste in landfills, saving natural resources, and decreasing pollution. Crushing and sieving waste from standard compression test cubes is used to produce the recycled concrete aggregate (RCA). A set of standard concrete cylinders, cubes, and beam specimens were made by utilizing coarse aggregate replacement ratios of 0%, 30%, 50% and 70%. At the day 28 stage, the specimens were tested to determine compressive strength, stress–strain relationship, splitting tensile strength, and flexural strength. In addition, four reinforced concrete (RC) beams were cast and tested under a four-point load to evaluate the flexural behaviour of RC beams with partial replacement of the natural aggregate with RCA. One was a natural aggregate (NA) control beam, while the others had varying RCA ratios (30%, 50% and 70%). The results show that the compressive strength of RCA concrete with the replacement by 30%, 50% and 70% decreased by 9.10%, 18.88% and 22.57% respectively, in comparison to the compressive strength of normal concrete (NC). The RCA concrete showed a high strain capacity, which indicated high ductility. The maximum RCA type strains ranged from 0.0056 to 0.0072. Concrete flexural strength showed a slight decrease in comparison to NC (18.83% decrease), where the tensile strength showed a 10.61% decrease in comparison to NC. As for RC beams, the load-carrying capacity decreased by 10.5% with increases in the replacement ratio.

Published: January 2023

This study shows the results of long-term inland water monitoring using Sentinel-2 data for Głuszyńskie Lake in the years 2015–2022. Four water quality parameters: biological oxygen demand (BOD), dissolved organic carbon (DOC), chlorophyll concentration (CHL) and electrical conductivity (EC) were calculated according to formulas found in the literature. The results were validated based on measurements conducted in 2021 and 2022, where for BOD, DOC and CHL high determination coefficients (0.77 and 0.79) were observed, and the EC determination coefficient was equal to 0.45. The results show that empirical formulas can be used for qualitative analyses of inland water quality, while for quantitative analyses more extensive field work needs to be performed.

Curriculum development is an essential part of activities carried out for students in school, which cannot be overlooked. It is carried out to help students to cope with discoveries and other definite activities in their lives. Literacy curriculum development is all about acquiring skills, applied, practiced and socially situated for learning and teaching processes. The purpose of the study is to examine the concept of literacy curriculum development, the factors guiding literacy curriculum development and the importance of literacy curriculum development to education. Specifically, the study reviews studies that impact teaching and learning in schools, and the factors influencing literacy curriculum development. This study is significant because literacy curriculum development would influence qualitative standards in education in the country. It would also improve the confidence of students and teachers of Basic Science and Management Science. The conclusion drawn for the paper is that literacy in curriculum development should be seen as a major step, which would provide solution to educational problems by incorporating the new developments in the society. It would also contribute greatly to the effectiveness of teaching and learning in the classroom.
Central African Republic: The West Contra Russia in the Conflict Solution
Authors: Majchút Ivan
Published: January 2023

The Central African Republic, located in the central part of Africa, has been known for decades of conflict between the communities. Citizens of local communities first influenced the solution to the conflict. However, the mentioned country cannot solve it, and external actors must contribute to these processes. International organisations (United Nations, European Union, and African Union) and the powered world countries (the United States of America, China, and France) were also significant, active, and influential in this process. Russia obtained a unique position in the process. The present study attempted to critically evaluate this country's historical background, current conflict situation, and perspectives. The study aimed to answer the essential question of the external players, activities, and roles in the Central African Republic and asserted their interests in the mentioned region by the complex of general theoretical methods. Special attention was paid to Russian activities in this country. It is obvious that the mutual relations of external actors fundamentally influence the situation in the mentioned country. The conflict situation in the country was affected, is affected, and will be affected not only by inside processes but also by outside processes.

The state and its administration have been constantly confronted with profound changes, which they not only faced, but which must be shaped in order to better fulfil their diverse tasks and be able to fulfil their responsibilities. One such modern and fast-moving change is digitalization, which affects every area of life. The potential of digitalization has, of course, also affected the administrative activity of the state, from the design of optimal framework conditions for the economy and society through the improvement of infrastructure to more efficient administrative work. The aim of the article was to identify the key moments in building e-Government in Germany and, in the context of assessing its current state, to identify the main shortcomings of German e-Government. In this context, we have focused on defining and clarifying the nature of e-Government, introducing the positives and negatives. In the second part, we have focused on a brief analysis of the development and current state of implementation of the e-Government concept in Germany. The biggest shortcoming of the German public administration in terms of digitalization is the issue of effective interconnection of online services into one functioning overall system. There is still no central portal in Germany that contains all the information and service offers from a single source. It is still in the process of building. Even public registers, i.e., data collection and office archives, are not sufficiently interconnected. It requires, first and foremost, political will, an attractive range of services, initial investment as a driving force and a source of inspiration, and municipalities and Länder are also key in this process as the first points of contact for citizens

Anatomical features of the teeth should be accounted for dental treatment plans. The need for constant monitoring of changes in the dentition system determines the relevance of this research. The study aimed to establish the size of anterior teeth with the help of odontometry. We made bi-layer single stage impressions and cast diagnostic models of the anterior teeth of 50 male and 50 female participants aged 18–24 years. The absolute sizes of crowns of incisors and canines were established. To assess the reduction of lateral incisors, we calculated the interincisor index (Ii) of teeth 22 and 21; sexual dimorphism was determined using the Garn–Lewis formula. It was discovered that there are no differences in the mesiodistal widths of crowns of contralateral teeth on the right and left sides (p > 0.05). The mesiodistal width of crowns of anterior teeth decreases (significant changes) in the following order: maxillary central incisors → maxillary canines → mandibular canines and maxillary lateral incisors → mandibular lateral incisors → mandibular central incisors. The degree of reduction of lateral incisors is low (Ii = 74.9) and more prominent in males than in females. In the examined patients, the greatest mean length of crowns of anterior teeth is that of upper central incisors and lower canines, while upper canines are shorter in length and upper lateral incisors, lower central and lateral incisors have the shortest mean crown length. Males have longer (mean length) crowns of lower canines, upper incisors and canines than females, the difference being significant (p < 0.001). The parameters of the crowns determined in this study showed that they have sufficient height and mesiodistal width, which, together with the low degree of reduction of the lateral incisors, justifies the possibility of direct fabrication of orthodontic fixed retainers. The data can also be used at the stage of dental treatment planning.
The Transmogrification of Surgical Telehealth: a PRISMA Review

Telehealth has been used to care for patients at a distance in specific clinical and demographic situations, but the demand for physical isolation during the COVID-19 pandemic has expanded its application to the broader community. This systematic literature review, of very recent publications, elucidates the new ways telehealth has been implemented, confirms it’s acceptability, accessibility and safety by collating reviews, trial and cohort studies from peer reviewed journals meeting defined risk of bias criteria.
Five literature reviews, three qualitative studies and 22 quantitative studies were included, which confirmed that telehealth is a safe medium for delivery of surgical health care, is accessible and efficient for the majority of patients and clinicians across the age and socioeconomic spectrum. It is time and resource efficient for providers and recipients and improves the delivery of patient-centred care. Many providers have published innovative solutions to the difficulties of telehealth, such as conducting a physical examination or technological limitations at the remote site. Health care can now be delivered directly to the home or the workplace.
Routine in-person postoperative review of patients should be replaced by patient-led telehealth unless there is a specific reason for face-to-face review. Assessment and management of new cases could be managed more efficiently if a carefully planned digital referral process is developed and adopted.

The teacher frequently asks questions in the form of algorithms without challenging the student to think at a higher level and nearly never gives daily questions. As can be observed, some teachers have not done competency assessments and hence do not require pupils to accomplish specific competencies. The purpose of this project is to create school collaboration worksheets and examine student responses to these problems, with the goal of implementing learning through the Lesson Study for Learning Community (LSLC) method. This study employs a qualitative approach and a design research method. Design research is divided into two stages: development research and design research. The study's subjects were seventh-grade pupils from SMPN 1 Merauke. This investigation culminated in the development of worksheets on direct comparisons and integers. According to the results of the examination of students' responses to the LKS, some students were able to solve problems effectively, indicating that this LKS was legitimate and useful for use

AbstractThis article is the result of virtual learning research with research subjects of two groups of students and aims to determine the effectiveness of metacognitive learning so that the components of metacognition in solving problems can be analyzed. The research begins with a pre-test followed by virtual learning and ends with post-test and metacognition questionnaires. During the post-test, students' activities in solving them were observed through awareness, evaluation, and regulation while the metacognition questionnaire consisted of questions about metacognition components. The results of the data analysis show that students who do metacognition, their learning outcomes increase so that there is a relationship between the components of metacognition and the ability to solve problems. This relationship is expressed by the correlation coefficient rxy = 0.419 with the regression equation y = 61.02 + 0.287x. This means that each metacognition independent variable can increase the average problem solving dependent variable by 0.287 units. Statistically, metacognitive learning is quite effective in solving problems. Based on these final results it can be recommended that virtual learning with a metacognitive model can be used as a new way and becomes a strong motivation for students to improve their ability to solve problems. Keywords: effectiveness, metacognition questionnaire homogeneous, interpretation, virtual learning. AbstrakArtikel ini merupakan hasil penelitian pembelajaran virtual dengan subjek penelitian dua kelompok mahasiswa dan bertujuan untuk mengetahui efektivitas pembelajaran metakognitif sehingga komponen metakognisi dalam memecahkan masalah dapat dianalisis.  Penelitian diawali dengan pre-test yang dilanjutkan dengan pembelajaran virtual dan diakhiri dengan pemberian post-test dan  angket metakognisi. Selama post-test, diamati aktivitas mahasiswa dalam menyelesaikannya melalui kesadaran, evaluasi, dan regulasi  sedangkan angket metakognisi berupa pertanyaan tentang  komponen metakognisi. Hasil analisis data menunjukan mahasiswa yang melakukan metakognisi, hasil belajarnya meningkat sehingga ada hubungan antara komponen metakognisi dengan kemampuan menyelesaikan masalah. Hubungan tersebut dinyatakan oleh koefisien korelasi rxy = 0,419 dengan persamaan regresi y = 61,02 + 0,287x. Hal ini berarti bahwa setiap variabel independen metakognisi dapat meningkatkan rata-rata variabel dependen pemecahan masalah sebesar 0,287 satuan. Secara statistika  pembelajaran metakognitif cukup efektif dalam pemecahan masalah. Berdasarkan hasil akhir tersebut dapat direkomendasikan bahwa pembelajaran virtual dengan model metakognitif dapat digunakan sebagai cara baru dan menjadi motivasi yang kuat bagi mahasiswa untuk meningkatkan  kemampuan dalam menyelesaikan masalah. Kata kunci: angket metakognisi, efektivitas, homogen, interpretasi, pembelajaran virtual.
