The objective of this research was to analyze the effect of different concentrations of nitric and hydrochloric acids on the structural, acidic, and catalytic properties of a post-synthetic treated ZSM-5 type zeolite at various temperatures. The properties of zeolite catalysts were determined using different methods, such as the Brunauer-Emmett-Teller (BET) method for specific surface area, temperature-programmed desorption (TPD) of ammonia method for acidic properties, and a flow-through unit with fixed bed catalyst (with upgrading straight-run gasoline fraction of oil) for catalytic activities of initial zeolite and acid-treated samples. The structural and acidic properties of both untreated and treated zeolites were investigated, and the effect of acid treatment on the catalytic properties of the samples in the course of upgrading the straight-run gasoline fraction of oil was determined. The post-synthetic treatment with aqueous nitric acid increased the specific surface area and volume of micropores of ZSM-5 zeolite, while the treatment with aqueous hydrochloric acid led to the formation of mesopores. Acid treatments of zeolite decreased the number of acid sites, mainly due to diminished concentration of low-temperature sites. The yield of liquid products in the conversion of straight-run gasoline fraction of oil, i.e., generation of high-octane gasolines with improved environmental features, was increased using acid-treated zeolites, which was due to the decrease in arene content.

Published: December 2021

BACKGROUND

Lockdowns imposed during the COVID-19 pandemic have impacted the living and working habits of millions of people, with potentially important implications for their physical, mental, and social well-being.

OBJECTIVE

The primary objective of this study was to investigate the impact of the COVID-19 pandemic on remote workers who were not directly affected by COVID-19.

METHODS

This was a correlational cross-sectional study (with an additional qualitative component) of 184 remote workers surveyed during the first COVID-19 lockdown in the United Kingdom. Standard measures of mental health (Kessler-6 Distress Scale), productivity (Brief Instrument to Assess Workers’ Productivity During a Working Day), and physical activity (International Physical Activity Questionnaire) were used, and respondents were further surveyed on changes to their dietary, exercise, smoking, drinking, and socialization habits to produce a well-being change index.

RESULTS

The results revealed associations between sedentary behavior and poorer mental health (τb=0.14) and between poorer mental health and low work productivity (τb=–0.39). However, both positive and negative lifestyle changes were reported; a self-reported increase in well-being (with respect to diet, exercise, smoking, alcohol consumption, and socialization) since the start of the pandemic was associated with both better mental health (τb=–0.14) and better work productivity (τb=0.14). Of note, among respondents without a mental health diagnosis (137/184, 74.4%), we observed rates of moderate (76/137, 55.5%) and severe (17/137, 12.4%) psychological distress, which were markedly higher than those reported in large prepandemic studies; moreover, 70.1% (129/184) of our respondents reported more sedentary behavior, 41% (69/168) increased their alcohol consumption, and 38.6% (71/184) increased their overall food intake. However, 46% (75/163), 44.8% (39/87) and 51.8% (57/110) of respondents reported spending more time walking and engaging in more moderate and vigorous exercise, respectively. Qualitative analysis revealed many positive adaptations to lockdowns (eg, decreased commuting expenses, flexibility) but also a number of structural obstacles to remote working (eg, lack of support and high expectations from employers, childcare duties).

CONCLUSIONS

These findings may be of practical importance for policy makers and employers in a world in which work involves long-term remote or hybrid employment arrangements; strategies to promote more sustainable remote working are discussed.

Published: December 2021

BACKGROUND

Disproportionate risks of COVID-19 in congregate settings including long-term care homes, retirement homes, and shelters both affect and are affected by SARS-CoV-2 infections among facility-staff. In cities across Canada, there has been a consistent trend of geographic clustering of COVID-19 cases. However, there remain limited data on how COVID-19 among facility-staff reflect urban neighbourhood disparities, particularly stratified by the social and structural determinants of community-level transmission.

OBJECTIVE

To compare the concentration of cumulative cases by geography and social/structural determinants across three mutually exclusive subgroups in the Greater Toronto Area (population 7.1 million): community, facility-staff, and healthcare workers (HCW) in other settings.

METHODS

We conducted a retrospective, observational study using surveillance data on laboratory-confirmed COVID-19 cases (January 23 to December 13, 2020; prior to vaccination roll-out). We derived neighbourhood-level social/structural determinants from census data, and generated Lorenz curves and Gini coefficients to visualize and quantify inequalities in cases.

RESULTS

The hardest-hit neighbourhoods (comprising 20% of the population) accounted for 53.4% of community cases, 48.6% of facility-staff cases, and 42.3% of other HCW cases. Compared with other HCW, cases in facility-staff more closely reflected the distribution of community cases. Cases in facility-staff reflected greater social and structural inequalities (larger Gini coefficients) than other HCW across all determinants. Facility-staff cases were also more likely than community cases to be concentrated in lower income neighbourhoods (Gini 0.24[0.15-0.38] vs 0.14[0.08-0.21] with lower household density (Gini 0.23[0.17-0.29] vs 0.17[0.12-0.22]) and with a greater proportion working in other essential services (Gini 0.29 [0.21-0.40], 0.22[0.17-0.28]).

CONCLUSIONS

COVID-19 cases among facility-staff largely reflects neighbourhood-level heterogeneity and disparities; even more so than cases in other HCW. Findings signal the importance of interventions prioritized and tailored to home geographies of facility-staff in addition to workplace measures, including prioritization and reach of vaccination at home (neighbourhood-level) and at work.

Published: December 2021

The aim of this study was to evaluate the influence of vitamin and β-glucan supplementations on growth performance of growing-finishing pigs in Ben Tre province. A total of 36 post-weaned piglets (Duroc x Yorkshire-Landrace) with the initial live weight of 17.42 kg±0.26, was allotted into 3 treatments and 4 replications in a completely randomized design. There were three diets, including basal diet (BD) without any addition of β-glucan or vitamin (diet CT), the BD supplemented with vitamin (diet Vit) and the BD supplemented with β-glucan (diet Glu). The results on growth parameters indicated that final live weight (kg), weight gain (kg), and average daily gain (g/head/day) of pigs in the experimental diets were significantly higher (P<0.01) than those in the control treatment. FCR was lowest in Glu and highest in the control (P<0.01). Financial benefit based on feed and veterinary expenses was higher in the vitamin and β-glucan supplement diets than that of the control from 15.74% to 18.98%, respectively.

Published: December 2021

Background and objectives

Atrasentan reduces the risk of kidney failure but increases the risk of edema and, possibly, heart failure. Patients with severe CKD may obtain greater absolute kidney benefits from atrasentan but may also be at higher risk of heart failure. We assessed relative and absolute effects of atrasentan on kidney and heart failure events according to baseline eGFR and urinary albumin-creatinine ratio (UACR) in a post hoc analysis of the Study of Diabetic Nephropathy with Atrasentan (SONAR) trial.

Design, setting, participants, & measurements

The effect of atrasentan versus placebo in 3668 patients with type 2 diabetes and CKD with elevated albuminuria was examined in the SONAR trial. We used Cox proportional hazards regression analysis to study effects on the primary kidney outcome (composite of doubling of serum creatinine, kidney failure, or kidney death) and heart failure hospitalization across subgroups of eGFR (<30, ≥30–45, and ≥45 ml/min per 1.73 m2) and UACR (<1000, ≥1000–3000, and ≥3000 mg/g).

Results

Atrasentan reduced the relative risk of the primary kidney outcome (hazard ratio, 0.71; 95% confidence interval, 0.58 to 0.88) consistently across all subgroups of baseline eGFR and UACR (all P interaction >0.21). Patients in the highest UACR and lowest eGFR subgroups, in whom rates of the primary kidney outcome were highest, showed the largest absolute benefit (all P interaction <0.01). The risk of heart failure hospitalization was higher in the atrasentan group (hazard ratio, 1.39; 95% confidence interval, 0.97 to 1.99) and was consistent across subgroups, with no evidence that relative or absolute risks differed across eGFR or UACR subgroups (all P interaction >0.09).

Conclusions

Atrasentan reduced the relative risk of the primary kidney outcome consistently across baseline UACR and eGFR subgroups. The absolute risk reduction was greater among patients in the lowest eGFR and highest albuminuria category who were at highest baseline risk. Conversely, the relative and absolute risks of heart failure hospitalization were similar across baseline UACR and eGFR subgroups.

Published: December 2021

Background and objectives

Dietary potassium restriction in people receiving maintenance hemodialysis is standard practice and is recommended in guidelines, despite a lack of evidence. We aimed to assess the association between dietary potassium intake and mortality and whether hyperkalemia mediates this association.

Design, setting, participants, & measurements

A total of 8043 adults undergoing maintenance hemodialysis in Europe and South America were included in the DIETary intake, death and hospitalization in adults with end-stage kidney disease treated with HemoDialysis (DIET-HD) study. We measured baseline potassium intake from the Global Allergy and Asthma European Network food frequency questionnaire and performed time-to-event and mediation analyses.

Results

The median potassium intake at baseline was 3.5 (interquartile range, 2.5–5.0) g/d. During a median follow-up of 4.0 years (25,890 person-years), we observed 2921 (36%) deaths. After adjusting for baseline characteristics, including cardiac disease and food groups, dietary potassium intake was not associated with all-cause mortality (per 1 g/d higher dietary potassium intake: hazard ratio, 1.00; 95% confidence interval [95% CI], 0.95 to 1.05). A mediation analysis showed no association of potassium intake with mortality, either through or independent of serum potassium (hazard ratio, 1.00; 95% CI, 1.00 to 1.00 and hazard ratio, 1.01; 95% CI, 0.96 to 1.06, respectively). Potassium intake was not significantly associated with serum levels (0.03; 95% CI, −0.01 to 0.07 mEq/L per 1 g/d higher dietary potassium intake) or the prevalence of hyperkalemia (≥6.0 mEq/L) at baseline (odds ratio, 1.11; 95% CI, 0.89 to 1.37 per 1 g/d higher dietary potassium intake). Hyperkalemia was associated with cardiovascular death (hazard ratio, 1.23; 95% CI, 1.03 to 1.48).

Conclusions

Higher dietary intake of potassium is not associated with hyperkalemia or death in patients treated with hemodialysis.

Published: December 2021

Pseudomonas aeruginosa (PA) is part of a group of common nosocomial pathogens that exhibit multidrug resistance, thus proving to be a significant threat to healthcare. This study analyzes the ability of four commonly used antibiotics to observe eradication of the PA biofilm growth. Ceftazidime (CAZ), Tobramycin (TOB), Ofloxacin (OFLX), Meropenem (MEM), were tested against overnight cultures of PA strain PA01. The minimal inhibitory concentrations (MIC) of planktonic cells for all the four antibiotics were determined using broth microdilution while the minimal bactericidal concentrations (MBCs) were determined by colony count after antibiotic treatment and regrowth. Biofilm growth inhibition was performed by treating cells with antibiotic at the time of inoculation while eradication was determined by adding antibiotics 24 hours after inoculation, allowing mature biofilm formation, followed by the measurement of absorbance. PA planktonic cells exhibited highest susceptibility to MEM compared to overnight grown PA biofilm which demonstrated resistance to CAZ, complete sensitivity to ofloxacin, and minimal sensitivity to TOB and MEM. PA biofilm displayed dose-dependent sensitivity to TOB, MEM and OFLX, and a significant level of resistance to CAZ during inhibition phase. However, in the eradication phase, PA showed significant resistance to TOB followed by CAZ while PA biofilm showed sensitivity at higher concentrations of MEM. Our study exhibits that PA strain PA01 is resistant to ceftazidime in both planktonic and biofilm phases. While ofloxacin proved to be the most effective even at lower concentrations when compared with other antibiotics, tobramycin was most effective at higher concentrations for eradicating and inhibiting PA biofilms.

The paper discusses automated control systems for technological processes (APCS) of oil and gas producing enterprises of the Russian Federation. The history of the development of automated process control systems in oil and gas production is described. At the moment, the efficient operation of technological facilities is not possible without the use of automated control systems. Special attention should be paid to the fact that almost all oil production facilities are currently characterized by a high level of depletion and are mainly at the late (third or fourth) stages of operation. Under these conditions, the average production rate falls, the costs of technological procedures for oil and gas production increase significantly. In this regard, in the current conditions, the effective development of process control systems for oil and gas enterprises is an extremely urgent task. The paper provides a typical block diagram and classification of automated systems that provide control of technological processes in oil and gas production. The necessity of using an automated dispatch control system (ADCS) is substantiated and its main tasks are considered. The need for an automated process control system in oil and gas production to reach the next level of functional development, which can be provided by modern automation and communication means, is clearly demonstrated, thereby giving a new impetus to the digital transformation process. The concept of "smart" well is considered, comparative characteristics of different levels of oil fields are presented: standard, digital and intelligent. The concepts of big data (Big Data), cloud technologies (Cloud Storage), augmented reality are considered in relation to the specifics of the industry. A qualitative assessment of the readiness and development prospects of the APCS in the context of the transition to digital technologies in oil and gas production is carried out. The digital transformation of the industry must be economically substantiated and justified.

High-speed radio link HSRL is designed to transmit target information from spacecraft equipment to the ground. A block of onboard equipment for storing temporary data OESTD is a part of the onboard equipment of a high-speed radio link OEHSRL. Before the spacecraft is launched into space, acceptance tests of the input control are carried out. To do this, it was necessary to develop testing equipment TE and software for it. TE of OESTD is designed to check the OESTD in general and each block in particular during autonomous tests. This paper considers the subsystem of technological software - a component of the TE software system, which allows checking the operation of the FPGA as part of the OESTD. The subsystem main algorithms and functions performed by the subsystem are given. The interaction of the operator of control and testing equipment with programmable logic integrated circuits FPGA, which are part of the on-board equipment block for storing temporary data of the OESTD, is considered. Debugging software is required to enable this interaction. An FPGA with the RISC-V architecture was chosen, debugging via GRMON turned out to be impossible and OpenOCD was chosen. As a result, a technological software module was developed for testing and ensuring the operability of the FPGA as part of the onboard equipment for storing temporary data. The following components were developed: a subsystem for interaction with the device to ensure the ability to send commands and receive response messages, service functions to convert response messages into a readable form for the operator, a subsystem for interaction of the module with the main frame of the TE software, and widgets to provide the ability to manually enter commands from the user conveniently.

Authors:   Universidade Santa Cecília (Unisanta), Santos, SP, Brasil, de Oliveira Abud Carol , Pereira de Souza Luciano ,   Universidade Santa Cecília (Unisanta), Santos, SP, Brasil
Published: December 2021

Introdução: A recente celeuma em torno da COVID-19 paira sobre os direitos e deveres da população frente à vacinação e a imunização em massa. O exercício da liberdade individual e a eventual imposição de medida que torna compulsória a vacinação podem estar no foco de uma disputa política em torno da adoção de critérios científicos para a tomada de decisões governamentais que poderão trazer sérias consequências coletivas em relação à propagação e ao descontrole da doença. Objetivo:Estudar se a vacinação compulsória contra a COVID-19, uma vez instituída por lei ou ato normativo, terá fundamentação jurídica em face dos direitos fundamentais e analisar se a disputa política em torno da vacina pode estar influenciando a sua normatização. Método: Estudo exploratório e descritivo elaborado por meio de pesquisa documental e bibliográfica, coleta de textos provenientes da Organização Mundial da Saúde, do Ministério da Saúde, do governo federal, do estado de São Paulo, da análise da legislação pátria e de decisões recentes do Supremo Tribunal Federal. Resultados: Observou-se que é possível estabelecer a vacinação compulsória no Brasil assegurando os direitos fundamentais, entretanto, questões políticas estão influenciando a tomada de decisões pautadas por critérios técnico-científicos de Vigilância Sanitária. Conclusões: A restrição da liberdade individual encontra amparo no fundamento de busca pela saúde de interesse coletivo, desde que não extrapole os limites da integridade física do cidadão e da dignidade humana, vedado o uso da coerção física. A disputa política encabeçada por alguns agentes públicos pode ter acarretado atrasos e retrocessos na imunização vacinal da população brasileira, forma eficaz de controle da pandemia.

Language Situation in the Far North-East of Russia at the Border of the 20th–21st centuries
Authors:   Institute for the Development of Education and Advanced Training of Teachers, Mageramova Yulia Yu.
Published: December 2021

The article describes a specific linguistic situation that developed in the Far North-East of Russia (CWS) using the example of the Magadan region in the late 20th – early 21st centuries. The study used theoretical and empirical general scientific methods (analysis, synthesis, observation and generalization), as well as proper linguistic and sociolinguistic modifications of general scientific methods (quantitative and conceptual analysis, inclusive observation, interviewing native speakers). The main extralinguistic factors, under the influence of which the modern linguistic situation was formed, were determined: harsh climatic conditions, low population density, poorly developed transport infrastructure, remoteness from centers of science and culture, the presence of an autochthonous population, a heterogeneous and unstable composition of inhabitants, etc. It is proved that the combination of the influence of extralinguistic factors with the action of internal linguistic laws has led to the formation of a special linguistic situation on the CWS, which is characterized by the following features: the presence of borrowings from the languages of the indigenous peoples of the North, minimization of dialectal influence, the existence of a particular Kolyma regional dialect functioning in the region. As an illustration, there are examples of lexemes borrowed from the languages of autochthonous ethnic groups in the Russian literary language, in old-time dialects, in the Kolyma region. The article covers the issue of old-timers' dialects that have survived in certain settlements of the Magadan region but do not have an impact on the speech of the Kolyma residents today. The structure of the lexical-semantic level of the Kolyma region is described, it is represented by several types of localisms: semantic, lexical, relative and substratum regionalisms. The conclusion is made about the formation of a special linguistic situation in the Far North-East of Russia, which, on the one hand, is in many respects specific, and on the other hand, corresponds to the global trends in the development of language systems.
Migration processes among Tatars of the Tetyushsky krai: directions, causes and results (the second half of the 16th – early 20th centuries)
Authors:   Marjani Institute of History of Tatarstan Academy of Sciences, Salakhova Elmira K.
Published: December 2021

The presented article sets the tasks to consider the migration conditions and processes among the population of the Tetyushsky Krai, to identify the historical validity of their choice of a particular region for living, to determine the reasons that contribute to the movement of the population. The study of the history of the region in this perspective is being conducted for the first time. In our opinion, this approach to the study of local history is relevant. Ancestral ties in Tatar society have always been strong and representatives of the same family living in different regions maintained close contact and, therefore, kinship ties considerably affected the migration direction. In the course of our research, several directions of migration of the population of the Tetyushsky Territory were identified in different periods of history: after the fall of the Bulgarian state and, subsequently, the Kazan Khanate. The migration of certain clans took place on the territory of the current Spassky district of the Republic of Tatarstan. This movement was quite understandable, since in the memory of the people it was perceived as a movement within their land, their state. It is known that the territory of Volga Bulgaria stretched both in the left and right banks of the Volga River. It should also be noted that natives of the Tetyushsky Region founded some villages in the Almetyevsk and Spassk districts of the Republic of Tatarstan. The lack of arable land contributed to the movement of the population to the Menzelinsk district of the Ufa Province, in search of better conditions for farming. The connection of the inhabitants of the Mountain side with the southern city of Astrakhan is primarily due to its convenient geographical location for trade relations, which has been a favorite occupation of the Tatars since the beginning of centuries. Also, the climatic conditions of the southern region saved many in the hunger years in the Volga region. Those who moved from the Middle Volga region, mostly came from the Mountainous side. The study of the historical ties of the Tatars of different regions, migration processes and their directions provides new materials for researching the history of regions and settlements.

The aim of this study was to analyse the presence of histological infiltrations of neoplastic cells within the bone, and compare the distance of these infiltrations with the radiografic limits of the ameloblastoma. For this purpose, six integral surgical samples, with identifiable radiographic limits of the tumor, sent to the Pathology Service of Dental School of the Federal University of Rio Grande do Sul, were processed. From the results obtained, can be concluded that, although ameloblastoma presents well-defined radiographic limits, it is infiltrative from the histological view point. Infiltrations occurs at few and distinctive sites, varying in this study from 0.10 cm to 1.40 cm, related to the radiographic borders of the neoplasm.

Introduction: success rates of apical surgery are variable, and there are several causes of failure related in the literature. Among them, permeability of exposed dentin at the apical surface after apicoectomies has been receiving much attention, Nd: YAG laser irradiation can decrease this permeability, but its effects on root surface are not completely known. Objectives: evaluate morphological alterations of apical surface, specially surface smoothness, after Nd: YAG non contact laser irradiation, in different powers, in vitro. Material and Methods: thirty extracted human cuspids, maintained in distilled water had its crowns removed, and were endodontically treated in standard technique. Apicoectomy performed, removing 4 mm most apical of roots, using handpiece. Teeth were divided in three groups of 10 each. Half of the area of each apical surface was irradiated with Nd:YAG laser in non contact mode, for 30 seconds. Three different powers were used- three groups of 10 each. Half of the area of each apical surface was irradiated.

Reception of the Septuagint in the early church
Authors: Kubat Rodoljub
Published: December 2021

The aim of this paper is to portray the reception of the Septuagint in the
early Church. Firstly, the synagogue view of the translation is provided,
from the reports in which the origin of the translation is enthusiastically
discussed, to the rejection of the Septuagint. A particular emphasis is
placed on theological argumentation attempting to prove the divine
inspiration of the translation of the Seventy. In this process, the
prominent figures are: Justin Martyr, Irenaeus of Lyons, Clement of
Alexandria, Origen, Pseudo-Justin, Epiphanius of Salamis, Cyril of
Jerusalem, John Chrysostom and Augustine. The paper deals with two textual
disputes over the authenticity of the Septuagint text as the legitimate
successor of the original Hebrew consonant text. Textual deviations were
often a reason for such confrontations. The first dispute is between Julius
Africanus and Origen. Within it, Origen clarifies textual issues of certain
Old Testament books. Jerome and Augustine took part in the second dispute.
Jerome leaned more towards the Hebrew truth (Hebraica Veritas), while
Augustine put more stock into the translation of the Seventy. These
confrontations clearly reflect the status of the Septuagint in the early
Church. Finally, a concise review of the further status of the Septuagint in
the Western and Eastern Churches is provided.

Forests have been widely recognized as key habitats for odonate (dragonflies and damselflies) biodiversity, but the importance of forests for holding odonate biodiversity remains understudied in tropical mountains, one of the most diverse ecosystems on the planet. Here we described the odonate assemblage composition along the elevation gradient in the Tatamá Mountains (Colombian Cordillera Occidental). We analyzed the effects of elevation, habitat, and suborder on species richness and endemism. We found that the richest assemblage occurred in the foothills between 300 and 600 m, where the biotas of the Chocó biogeographic region and the Tropical Andes converge. Anisoptera richness was higher in open-habitat habitats, that of Zygoptera higher in forests. Richness and endemism decreased with elevation, and no relation between habitat and richness was found. However, the number of endemic species was strongly related to forests, which harbored 25 out of 28 endemic species. Also, forest odonates had narrower elevation ranges than open-habitat odonates. These patterns can be explained because tropical mountains were historically covered by forests, while open habitats derived from human activities (i.e., pastures) have flourished in the past centuries. The forest odonate assemblages at different elevations have been evolving for millions of years, in relatively stable ecological conditions, which could promote the high number of forest endemics in the tropical mountains. Our results emphasize the role of tropical mountain forests in the conservation of Odonata diversity.

Introducción: la alta prevalencia de trastornos del estado de ánimo en los pacientes con epilepsia, muchas veces interfiere en el correcto manejo farmacológico y psicosocial de la enfermedad. Las convulsiones en la mayoría de los pacientes con epilepsia pueden controlarse con medicamentos y en ocasiones con cirugía. De hecho, la epilepsia y los trastornos del estado de ánimo, como la depresión, afectan la calidad de vida y aumentan la discapacidad y, por tanto, los costos de atención médica. Objetivo: abordar las alteraciones del estado de ánimo que experimentan los pacientes epilépticos, en forma permanente, así como su respuesta a determinados estímulos ambientales, durante las crisis epilépticas o fuera de ellas. Metodología: se estudió un grupo de pacientes con epilepsia en el hospital Dr. Teodoro Maldonado Carbo (HTMC) de Guayaquil, para determinar la presencia de trastornos de estado de ánimo y sus características demográficas. Resultados: la relación existente entre los trastornos del estado de ánimo y la epilepsia, son más frecuentes entre los 14 y 26 años, con el 7.4%; mientras que entre los 27 y 59 años, representa el 1,42%. En el adulto mayor se asocia la epilepsia con enfermedades degenerativas. Los trastornos más frecuentes son la depresión y la ansiedad. Conclusión: es importante conocer la prevalencia de trastornos del estado de ánimo en la población epiléptica para proporcionar tratamiento apropiado para mejorar la calidad de vida de los pacientes y disminuir los costos para el sistema de salud.

Lack of teacher creativity in learning to develop instructional media makes learning less effective. Therefore, it is necessary to develop media that can make students enthusiastic about learning, such as digital comics. This research produces a product in the form of Digital Comic media on elementary school student style whose validity has been tested. The model used is the ADDIE model with the stages of Analyze, Design, Development, Implementation, Evaluation. In this study, digital comic media used as research subjects were 2 media expert lecturers, 2 material experts, 2 teachers. The method and instrument of data collection in this study is to use the rating scale method. To measure the validity of digital comic media using an instrument to assess the validity of digital comic media. The results of the data that have been obtained will be analyzed using the Aiken validity index formula for expert data and the mean formula for respondents' data in order to determine the validity of digital comic media. The results of the media validity on the Aiken validity index analysis, the assessment of the experts, got a score of 0.95 from the material experts with the criteria of "high validity", 0.95 from the media experts with the criteria of "high validity", while the analysis of the assessment scores of the respondents used the formula. The mean obtained an average of 4.57 from the practical response with the predicate "very good" and 4.50 from the student response with "very good". So, digital comic media is very suitable for use during the learning process, especially science learning.
