"Miguel García-Baró ha identificado en el desarrollo de la Filosofía tres navegaciones generales, y el sentido que le da a la expresión navegación filosófica es muy semejante al significado de las salidas del Quijote. La primera navegación es como la primera salida de don Quijote a las aventuras: sin escudero, sin dinero, sin haberse armado caballero, o sea, sin prevención alguna. En 99d del Fedón, Platón dice por boca de Sócrates que los pensadores habían navegado la primera vez como si pudieran tratar las cosas directamente, como si pudieran conducirse entre y con las cosas directamente, a fin de conocerlas. Pero esta confianza excesiva no resultó en conocerlas, sino en una crisis de incertidumbre que con el tiempo vendría a ser llamada escepticismo. No podía ser otro el desenlace si de la multitud de doctrinas incompatibles se afirma de todas ellas estar en la verdad. La segunda navegación de la Filosofía se ve germinal en Anaxímenes de Mileto, pero en Parménides y en Heráclito es ya un hecho consagrado. Consiste en la búsqueda de algo donde las cosas mismas se reflejen para no perecer ante la multitud de opiniones o ante un dogmatismo, ese algo fue el espejo del discurso, el Logos, el medio de la verdad donde se deja captar. El ser es estable, eterno, y este Logos nuestro que es el pensamiento, si acaso quiere aproximarse a la verdad, debe ser estable como el ser. Dos milenios de la Filosofía se han invertido en hacer del Logos, del juicio, el lugar primordial del conocimiento de la verdad; dos milenios y siga contando. Todavía cuando apareció la idea de una tercera navegación que descubra las formas más primitivas, elementales o remotas del conocimiento —en la persona de René Descartes—, el Logos o el juicio no perdió su lugar, pues esas formas remotas del conocimiento, precisamente, fueron buscadas para que nuestros juicios llegaran a esencias ideales. La primera navegación, primera salida de la Filosofía, consistió en el estudio de la naturaleza, incluyendo la búsqueda de un principio rector, tal y como se deja ver, por ejemplo, en Anaximandro de Mileto quien fuera el primero en escribir un tratado en prosa sobre los temas que, andado el tiempo, serían los de la Filosofía y de la ciencia, además de ser el primero en diseñar un mapa del mundo. La segunda navegación, que se emprende con el aprendizaje doloroso de los malogros de la primera, consiste en la teoría de la verdad, y como don Quijote, esta segunda salida no se realiza estando solo. La tercera se podría nombrar como teoría del conocimiento."

Published: March 2021

Introduction. The Russian Arctic, also called the Far North, attracts a lot of people who work on a fly-in fly-out basis. These temporary residents experience the negative impact of the harsh climate and suffer from unvaried diets and poor ration. Freeze-dried products might be the optimal solution to this problem. The research objective was to find a rationale for the use of freeze-dried long-storage products in the diets of temporary residents in regions with harsh climatic conditions. Study objects and methods. The research featured scientific publications on two topics: 1) nutrition and diet of shift workers in the Far North, 2) development of freeze-dried products for long-term storage in extreme conditions. Results and discussion. Shift workers consume a lot of fats and carbohydrates, while their diet lacks complete proteins, vitamins, minerals, dairy products, and fresh fruits and vegetables. Taking into consideration the high content of sugar and confectionery, the diet ruins the health of the temporary residents and causes alimentary chronic non-infectious diseases. A healthy diet for the Russian Arctic should correspond to the metabolic profile typical of people in chronic environment stress and be complete both quantitatively and qualitatively. Important food products are difficult to deliver to the Far North. As a result, they are microbiologically and chemically contaminated. Therefore, the region needs high-quality functional products with prolonged shelf life. Conclusion. Freeze-dried fermented milk products, fruits, and vegetables can help temporary residents of the Far North to maintain their usual food patterns. Freeze-dried foods have a long shelf life in unregulated temperature conditions, which can solve the issue of food supply even to the most remote settlements.

Published: March 2021

Introducción: la diabetes mellitus tipo dos es una enfermedad crónica de gran impacto en salud pública; su mal control clínico está supeditado a la deficiente adherencia farmacológica. Los programas de nefroprotección intentan mejorar el control de esta enfermedad y una adecuada adherencia puede ser una estrategia. El objetivo del estudio fue determinar los factores asociados con la adherencia farmacológica de pacientes con diabetes en el contexto de un programa de nefroprotección. Materiales y métodos: estudio transversal analítico en 282 pacientes con diabetes mellitus tipo dos de un programa de nefroprotección en los municipios de Pasto y Túquerres en el año 2017, seleccionados mediante muestreo aleatorio, sistemático estratificado. La adherencia se midió con el test Morisky-Green. La información se obtuvo de bases de datos de las historias clínicas y mediante un cuestionario estructurado. Se efectuaron análisis descriptivo, bivariado y regresión logística binaria multivariada con fines explicativos. Las medidas de asociación fueron razones de prevalencia (RP). Resultados: la mediana de la edad fue de 67 años, 33 % fueron hombres y la proporción de adherencia del 68 %; los factores que se asociaron independientemente fueron, ser mujer RP: 1,25 (IC 95 %: 1,02-4,07), hemoglobina glicosilada entre 6 y 6,9 % RP: 1,66 (1,37-11,80), no uso de insulina RP: 1,36 (1,03-8,52), empleo de solo metformina RP: 1,76 (1,76-10,15) y consulta por medicina interna RP: 1,19 (1,19-4,78). Conclusión: la adherencia farmacológica está influenciada por múltiples factores que no sólo dependen del paciente, sino que involucran también a los profesionales de salud, el tipo de medicación y su disponibilidad, además de asociarse con el control glucémico.
Improved model for predicting the hydraulic conductivity of soils based on the Kozeny–Carman equation
Authors: Wang Mengting , Wang Jianjun , Xu Guangli , Zheng Yuhao , Kang Xuan
Published: March 2021

The saturated hydraulic conductivity of soils is a critical concept employed in basic calculation in the geotechnical engineering field. The Kozeny–Carman equation, as a well-known relationship between hydraulic conductivity and the properties of soils, is considered to apply to sands but not to clays. To solve this problem, a new formula was established based on Hagen–Poiseuille's law. To explain the influence on the seepage channel surface caused by the interaction of soil particles and partially viscous fluid, the surface area ratio was introduced. A modified framework for determining the hydraulic radius was also proposed. Next, the relationship between the effective void ratio and the total void ratio was established for deriving the correlation of hydraulic conductivity and total void ratio. The improved equation was validated using abundant experimental results from clays, silts, and sands. According to the results, the accuracies of the proposed model with two fitted multipliers for clays, silts, and sands are 94.6, 96.6, and 100%, respectively, but with only one fitted parameter, the accuracies are 97.1, 91.5, and 100%, respectively. The proposed model can be considered to have a satisfactory capability to predict hydraulic conductivity for a wide variety of soils, ranging from clays to sands.

Published: March 2021

Reclaimed water has demonstrated its broad applications in social construction to alleviate the contradiction of water shortage in Beijing, China. Using multivariate statistical analysis, the current study investigated the spatial variations of water quality in the Chaobai River restored by reclaimed water during the high-flow period. Hierarchical cluster analysis (CA) classified the 11 sampling sites into four clusters, namely most polluted, highly polluted, moderately polluted, and lowly polluted sections. The Kruskal-Wallis test showed that pH, TDS, EC, Ca2+, Mg2+, Cl−, SO42−, NO3−-N, and TN had significant spatial differences among four clusters (p < 0.05). Mean value of total nitrogen (TN) in the most polluted site exceeded the guideline (15 mg/L) of the Water Quality Standard for Scenic Environment Use, reaching 22.3 mg/L. Principal component analysis (PCA) extracted three principal components (PCs) accounting for 81.5% of the total variance in the data set of water quality. The three PCs reflected the chemical characteristics of reclaimed water, mineral pollution, and nutrient pollution, respectively. With the ordination biplot of sampling sites defined by the first and second PCs, PCA provided a classification of sampling sites based on the similarity of pollution sources, which supported the results of CA. The results revealed that water quality of the Chaobai River restored by reclaimed water was affected by untreated domestic and agricultural sewage with nitrogen and minerals being the main pollutants along the river basin. This study showed rivers restored by reclaimed water had significant spatial variations of water quality, demonstrating effectiveness of multivariate statistical methods on water quality analysis.

Authors: Bublikova M. A. , Khokhlov I. P.
Published: March 2021

Aim. JSC RZD is one of the largest and most advanced companies in Russia who actively deploys and uses best practices in asset and risk management. In 2010, the railway industry initiated the project for the management of resources, risks and dependability at lifecycle stages of railway facilities (URRAN) that is currently under way. The aims of this paper are to overview the asset management tasks covered by URRAN; examine the marketed IT tools designed to address such problems; present the progress of the URRAN project in terms of process automation implemented by JSC RZD in light of the international best practice and the specificity of the Company.

Methods. The preparation of this paper involved empirical and theoretical research. The authors analysed the URRAN project’s package of guidelines and regulations, public information on the globally available software products enabling asset management, as well as the program documentation of the EKP URRAN automated system. They analysed the functionalities and and engineering solutions used in the development of this automated system. The results of the EKP URRAN deployment and practical application by units and branches of JSC RZD were evaluated.

Results. Asset management involves using Enterprise Asset Management Systems (EAMS) specially designed to suit the needs of specific companies or mass-produced “out-of-the-box” systems, e.g. SAP ERP, IBM MAXIMO, ABB AbilityТМ and SimeoTM that are examined in the paper. The EKP URRAN implements a single information space that is a decision support tool for the asset management system as it possesses the required regulatory and procedural resources, hardware and software assets intended for comprehensive management of assets and processes for the purpose of efficient railway service. In the future, the EKP URRAN is to become part of the Digital Platform for Risk and Traffic Safety Management deployed in JSC RZD and will comprise modules that implement dynamic predictive analytics models for the purpose of predicting undesirable events involving infrastructure and rolling stock that may disrupt traffic safety.

Conclusions. Further development of the EKP URRAN will soon provide all levels of company management with an efficient tool that allows, in the context of limited resources, making substantiated managerial decisions and rational investment allocation. The EKP URRAN is an asset of JSC RZD designed to be used by the managers and specialists of various JSC RZD units. It can be implemented as a standalone IT product for the purpose of developing and deploying an asset management system in various railway companies.

Carcinoma de Vesícula Biliar: diagnóstico tardio e prognóstico sombrio
Authors: Carreiro Schmidt Letícia , Renna Júnior Nelson Luiz
Published: March 2021

O carcinoma de vesícula biliar é uma neoplasia rara, agressiva e que trás um prognóstico sombrio, isso porque é habitual o diagnóstico da mesma em um estágio avançado em decorrência das manifestações clínicas e sintomas apresentarem-se tardiamente. Apresenta-se geralmente entre a 6ª e a 7ª décadas de vida e é de 2 a 3 vezes mais comum no sexo feminino em comparação ao masculino. Muitos carcinomas de vesícula, sendo na maioria destes adenocarcinoma, possuem a doença sistêmica no momento do diagnóstico, com doença nodal (35%) e metástases a distância (40%) ou até mesmo invasão de grandes vasos, preenchendo-se então critérios de inoperabilidade e tornando a neoplasia fatal. O presente artigo buscou abordar o tema em questão, realizando busca a partir das palavras chaves e selecionando 11 artigos científicos somados a outros por pesquisa manual referenciados nos artigos previamente selecionados e um livro texto, para se compreender acerca dos fundamentos que justifiquem o fato de sua identificação atrasada ser altamente fatal. Por conseguinte, de acordo com as literaturas avaliadas, pode-se concluir que o diagnóstico tardio e prognóstico sombrio do carcinoma de vesícula biliar se dá pelo fator anatômico de localização da maioria destes, que fazem com que os sintomas se sobressaiam tardiamente. Não obstante, àqueles com diagnóstico incidental, possuem um prognóstico melhor e são mais sujeitos ao tratamento curativo, com uma vantagem na taxa de morbimortalidade. Tendo em vista, se torna necessário avanços cirúrgicos no tratamento desta doença, além de estratégias para detecção precoce da mesma.

Published: March 2021

Background:

Sufficient attention was not paid to the effects of microtubule-associated
protein tau (MAPT) and plasma tau protein on cognition.

Objective:

A total of 3072 people in rural China were recruited. They were provided with questionnaires,
and blood samples were obtained.

Methods:

The MMSE score was used to divide the population into cognitive impairment group
and control group. First, logistic regression analysis was used to explore the possible factors influencing
cognitive function. Second, 1837 samples were selected for SNP detection through stratified
sampling. Third, 288 samples were selected to test three plasma biomarkers (tau, phosphorylated
tau, and Aβ-42).

Results:

For the MAPT rs242557, people with AG genotypes were 1.32 times more likely to develop
cognitive impairment than those with AA genotypes, and people with GG genotypes were 1.47
times more likely to develop cognitive impairment than those with AG phenotypes. The plasma tau
protein concentration was also increased in the population carrying G (P = 0.020). The plasma tau
protein was negatively correlated with the MMSE score (P = 0.004).

Conclusion:

The mutation of MAPT rs242557 (A > G) increased the risk of cognitive impairment
and the concentration of plasma tau protein.

Application of Artificial Intelligence for Screening COVID-19 Patients Using Digital Images: Meta-analysis
Authors: Poly Tahmina Nasrin , Islam Md Mohaimenul , Li Yu-Chuan Jack , Alsinglawi Belal , Hsu Min-Huei , Jian Wen Shan , Yang Hsuan-Chia
Published: March 2021

Background

The COVID-19 outbreak has spread rapidly and hospitals are overwhelmed with COVID-19 patients. While analysis of nasal and throat swabs from patients is the main way to detect COVID-19, analyzing chest images could offer an alternative method to hospitals, where health care personnel and testing kits are scarce. Deep learning (DL), in particular, has shown impressive levels of performance when analyzing medical images, including those related to COVID-19 pneumonia.

Objective

The goal of this study was to perform a systematic review with a meta-analysis of relevant studies to quantify the performance of DL algorithms in the automatic stratification of COVID-19 patients using chest images.

Methods

A search strategy for use in PubMed, Scopus, Google Scholar, and Web of Science was developed, where we searched for articles published between January 1 and April 25, 2020. We used the key terms “COVID-19,” or “coronavirus,” or “SARS-CoV-2,” or “novel corona,” or “2019-ncov,” and “deep learning,” or “artificial intelligence,” or “automatic detection.” Two authors independently extracted data on study characteristics, methods, risk of bias, and outcomes. Any disagreement between them was resolved by consensus.

Results

A total of 16 studies were included in the meta-analysis, which included 5896 chest images from COVID-19 patients. The pooled sensitivity and specificity of the DL models in detecting COVID-19 were 0.95 (95% CI 0.94-0.95) and 0.96 (95% CI 0.96-0.97), respectively, with an area under the receiver operating characteristic curve of 0.98. The positive likelihood, negative likelihood, and diagnostic odds ratio were 19.02 (95% CI 12.83-28.19), 0.06 (95% CI 0.04-0.10), and 368.07 (95% CI 162.30-834.75), respectively. The pooled sensitivity and specificity for distinguishing other types of pneumonia from COVID-19 were 0.93 (95% CI 0.92-0.94) and 0.95 (95% CI 0.94-0.95), respectively. The performance of radiologists in detecting COVID-19 was lower than that of the DL models; however, the performance of junior radiologists was improved when they used DL-based prediction tools.

Conclusions

Our study findings show that DL models have immense potential in accurately stratifying COVID-19 patients and in correctly differentiating them from patients with other types of pneumonia and normal patients. Implementation of DL-based tools can assist radiologists in correctly and quickly detecting COVID-19 and, consequently, in combating the COVID-19 pandemic.

Authors: Horsham Caitlin , Dutton-Regester Ken , Antrobus Jodie , Goldston Andrew , Price Harley , Ford Helen , Hacker Elke
Published: March 2021

BACKGROUND

Public health sun safety campaigns introduced during the 1980s have successfully reduced skin cancer rates in Australia. Despite this success, high rates of sunburn continue to be reported by youth and young adults. As such, new strategies to reinforce sun protection approaches in this demographic are needed.

OBJECTIVE

This study aims to develop a virtual reality (VR) game containing preventive skin cancer messaging and to assess the safety and satisfaction of the design based on end user feedback.

METHODS

Using a two-phase design approach, we created a prototype VR game that immersed the player inside the human body while being confronted with growing cancer cells. The first design phase involved defining the problem, identifying stakeholders, choosing the technology platform, brainstorming, and designing esthetic elements. In the second design phase, we tested the prototype VR experience with stakeholders and end users in focus groups and interviews, with feedback incorporated into refining and improving the design.

RESULTS

The focus groups and interviews were conducted with 18 participants. Qualitative feedback indicated high levels of satisfaction, with all participants reporting the VR game as engaging. A total of 11% (2/8) of participants reported a side effect of feeling nauseous during the experience. The end user feedback identified game improvements, suggesting an extended multistage experience with visual transitions to other environments and interactions involving cancer causation. The implementation of the VR game identified challenges in sharing VR equipment and hygiene issues.

CONCLUSIONS

This study presents key findings highlighting the design and implementation approaches for a VR health intervention primarily aimed at improving sun protection behaviors. This design approach can be applied to other health prevention programs in the future.

BACKGROUND

To demonstrate the value of implementation of an artificial intelligence solution in health care service, a winning project of the Massachusetts Institute of Technology Hacking Medicine Brazil competition was implemented in an urgent care service for health care professionals at Hospital das Clínicas of the Faculdade de Medicina da Universidade de São Paulo during the COVID-19 pandemic.

OBJECTIVE

The aim of this study was to determine the impact of implementation of the digital solution in the urgent care service, assessing the reduction of nonvalue-added activities and its effect on the nurses’ time required for screening and the waiting time for patients to receive medical care.

METHODS

This was a single-center, comparative, prospective study designed according to the Public Health England guide “Evaluating Digital Products for Health.” A total of 38,042 visits were analyzed over 18 months to determine the impact of implementing the digital solution. Medical care registration, health screening, and waiting time for medical care were compared before and after implementation of the digital solution.

RESULTS

The digital solution automated 92% of medical care registrations. The time for health screening increased by approximately 16% during the implementation and in the first 3 months after the implementation. The waiting time for medical care after automation with the digital solution was reduced by approximately 12 minutes compared with that required for visits without automation. The total time savings in the 12 months after implementation was estimated to be 2508 hours.

CONCLUSIONS

The digital solution was able to reduce nonvalue-added activities, without a substantial impact on health screening, and further saved waiting time for medical care in an urgent care service in Brazil during the COVID-19 pandemic.

Published: March 2021

Asphalt concrete of various brands is mainly used as a road surface. The quality and durability of the coating depends on its density. To achieve the required density of the asphalt concrete pavement, road rollers are used. The working body of the roller is a metal drum or a set of pneumatic tires. The article discusses the process of the asphalt concrete mixture compaction with a smooth metal drum. A rheological model of the force interaction of a smooth drum with a material is adopted, which includes elastic, viscous and plastic elements. The adopted model was corrected taking into account the investigated process of elastic aftereffect that occurs in the asphalt concrete mixture during compaction. The law of behavior of asphalt-concrete mixture with elastic aftereffect is established. A simulation model has been developed to study the behavior of a material in the process of elastic aftereffect. In the course of dynamic modeling, the relationship between the physical and mechanical characteristics of the compacted material with the design and technological parameters of the road roller was established. A statistical analysis of the design parameters of existing models of road rollers has been carried out. The results of the analysis, as well as the obtained dependencies, can be used to designate the technological modes of operation of a set of road rollers when compacting the asphalt concrete pavement of a motor road. Taking into account the elastic aftereffect when assigning the operating modes of the compaction equipment will improve the compaction efficiency, as well as the quality of the resulting coating.
Epistemología en Enfermería. Una revisión del acto de cuidar desde Michel Foucault, el modelo de Roper, Logan & Tierney y el concepto de “bildung” de Gadamer
Authors: Firpo Rosana Elisabet
Published: March 2021

Desde mediados del siglo pasado el sustento teórico de la disciplina Enfermería se nutrió a través de la elaboración de teorías y modelos de diferente rango y orientación, la mayoría de ellos originados en los Estados Unidos (Henderson, Peplau, Rogers, Leininger, Orem, por citar sólo los más conocidos). De hecho, en la Universidad de Iowa se desarrolló una taxonomía diagnóstica con el propósito de homogeneizar el lenguaje enfermero[1] que al día de hoy cuenta con una importante aceptación a nivel mundial en lo que respecta al desarrollo de los planes de cuidado.
Sin embargo, el intento de imponer esos modelos teóricos en el contexto de América Latina -más que nada por parte de los ámbitos académicos- ha sido muy resistido. A fin de revisar el sustrato filosófico de la adopción de un modelo teórico para la disciplina Enfermería, desde este trabajo se parte de la concepción de persona desde Michel Foucault como ser de vida, trabajo y lenguaje y se recurre al concepto de bildung (Gadamer, 2004) entendido como “edificación” para orientar una necesaria revisión en lo que hace al objeto de estudio y trabajo de la Enfermería.
A partir de hacer énfasis en la persona (familia/comunidad por extensión) destinataria de los cuidados, se propone explicitar la articulación de los tres planos del cuidado a fin de dotar identidad a la disciplina Enfermería al superar el enfoque instrumental y tecnocrático que en general ha teñido a la profesión.
En este camino, se acuerda con Richard Rorty (1979) en la necesidad de mantener el diálogo –en este sentido la taxonomía diagnóstica de la NANDA sería un obstáculo- y se postula un objeto de estudio interdisciplinar que ponga a conversar a las diferentes disciplinas involucradas en el acto de cuidar y se considera que desde el Modelo de Roper, Logan y Tierney, al incluir los determinantes sociales de la salud, es posible tender puentes no sólo hacia la interdisciplina sino además hacia la intersectorialidad.

Complejidad y cuidado emergente
Authors: Ré Cecilia
Published: March 2021

La postmodernidad surge con el paradigma de las Ciencias de la Complejidad (CC) con apoyo a teorías, modelos y prácticas de cuidado holístico. Rompen con postulados prevalentes. Abiertas al desarrollo teórico innovador, la experimentación y la investigación, reconstruyen los conocimientos con omnipresencia cognoscitiva universalista. Fundadas en la física cuántica, las matemáticas cualitativas y la informática, los conocimientos y las teorías científicas galenas están en revisión, aunque cierras los ojos ante ciertos hallazgos. La Enfermería tiene la oportunidad de superar los límites lineales impuestos por la estructura racional científica, evidente, circunscripta a la materialidad, acobijadas por el modelo médico hegemónico (MMH).

Authors: Rakutko S. A. , Rakutko E. N. , Mishanov, A. P.
Published: March 2021

The authors showed that a convenient, accurate and fast way of assessing the degree of influence of environmental factors on plants was needed to optimize photoculture. They emphasized the importance of non-destructive monitoring of crops physiological state of, for which they used phenomics technologies, for example, remote sensing using hyperspectral cameras.

(Research purpose) To reveal the possibility of using hyperspectral imaging to determine the plant developmental stability.

(Materials and methods) As a measure of the favorable impact of environmental factors on the growth and development of plants, their developmental stability was taken, numerically characterized by the fluctuating asymmetry value. The authors proposed to use vegetation indices determined from the leaf reflection spectra as a bilateral feature. The object of experimental research was juvenile cucumber plants. The studies were carried out in laboratory conditions. The spectral characteristics of cucumber leaves grown under different light quality of radiation were determined using a Specim IQ hyperspectral camera. Information on the spectral reflectances was extracted from the resulting data hypercube. As an example calculations were performed for Normalized Difference Vegetation Index.

(Results and discussion) The authors revealed differences in the productivity indicators of plants grown under different light quality. They revealed a significant frequency of occurrence of Normalized Difference Vegetation Index asymmetry in two halves of the cucumber leaf surface. The fluctuating nature of this asymmetry was confirmed. They found that with a light quality providing a higher productivity of plants, lower values of fluctuating asymmetry were observed, which indicate greater stability of plant development.

(Conclusions) The authors proposed a method for determining the plant developmental stability using a hyperspectral camera. The method was based on the assessment of the fluctuating asymmetry of vegetation indices calculated for points on the leaf surface, characterized by the same location conditions relative to the border of its left and right halves. A preliminary assessment of the possibility of determining the developmental stability by the results of phenotyping using the example of cucumber plants showed the feasibility of the method and its practical applicability.

Authors: Epifantsev V. V. , Osipov Ya. A. , Vaytekhovich Yu. A.
Published: March 2021

The authors showed that a rotary plow deepened the arable layer and destroyed the plow bottom, simultaneously crushed plant residues, green manure crops and embedded them in the soil upper layer that was active for the cultivated plants roots and microorganisms, which allowed providing them with available nutrients, maintained fertility and increased soybeans yield.

(Research purpose) To determine the soil deepener and the plow rotor agrotechnical parameters when working after different predecessors, to establish the dynamics of nutrients, soybean yield and to compare the technical indicators of various tillage implements.

(Materials and methods) The authors studied rotary plow indicators when cultivating the soil after green manure, wheat and soybeans: the tillage depth and the tooth linear speed, the rotor rotational speed and depth, crumbling, hardness and ridging of the soil surface, the presence of plant residues, specific fuel consumption, productivity. They conducted a comparative field experiment, meadow-chernozem-like soil was treated with tools: discs BDT-3.0 – control; plowshare PLN-3-35 and rotary plow PRN-2.5 M.

(Results and discussion) The authors determined that the tillage depth with the rotor was 0.143-0.149 meters, with the soil deepener – 0.25 meters, 25-27 percent of crop residues remained on the soil surface. It was found that the rotary plow details provided good soil cultivation, as a result of the incorporation of stubble and green manure, they contributed to a content increase of phosphorus in it by 11.8-13.3 percent, potassium – by 18-21.8, nitrogen – by 48.1-48.9 percent, which had a positive impact on the soybeans yield.

(Conclusions) The authors found a regular increase in soybean yields when processing the soil with a rotary plow by 0.32 tons per hectare compared to discs and by 0.06 tons per hectare compared to a share plow. It was suggested to use a rotary plow PRN-2.5 M. for soil cultivating for soybeans in the Amur region. They calculated the economic and energy feasibility of soil cultivating with a rotary plow in organic crop production.
