Carta a los profesores
Authors: Guebelly Ortega Jorge Elías
Published: October 2019

Apreciado profesor:

En este lento proceso de desnaturalización del hombre y de sus instituciones, es necesario detenerse un rato en el camino y reflexionar sobre nuestra Universidad, buscando su naturaleza original. El conocimiento debe ser el eje fundamental que regida las actividades universitarias. Conocimiento para ensanchar la conciencia del hombre. En fin de cuentas, este último proceso ha sido la base de toda la aventura humana.

En los recintos de la Universidad se imparte conocimiento: docencia; se crea nuevos conocimientos: investigación, y se comparte conocimientos: extensión. La docencia universitaria se levanta sobre el conocimiento más avanzado, factible de imprimir progreso al entorno social. Lo más avanzado en la ciencia, el arte, la tecnología, la filosofía, la religión... del mundo contemporáneo, sobre los rieles de metodologías igualmente avanzadas. La investigación universitaria desentraña los problemas acuciantes del entorno empleando los métodos investigativos más eficaces y más desarrollados, factibles de ser asimilados cieadoramente por la institución. La extensión universitaria es la socialización del conocimiento mediante el cual se combate todos los males de la comunidad buscando elevarla a un nivel más humano. Sólo así, la Universidad puede convertirse en una real alternativa de desarrollo material y espiritual de la sociedad que la generó.

Propuesta curricular alternativa para el ejercicio y la vivencia de los derechos humanos en las instituciones educativas
Authors: López Jiménez Nelson Ernesto , Pérez Gutiérrez María Fernanda , Perdomo Cortes Wilson Roberto
Published: October 2019

ste artículo tiene como propósito central analizar las expresiones del currículo oculto en algunas instituciones educativas del Departamento del Huila y sus implicaciones en las distintas formas de violencia escolar en el contexto de la política sobre los Derechos Humanos que existe en Colombia.

a problemática de los Derechos Humanos en América Latina y en Colombia ha adquirido una relevancia fundamental debido a la existencia de condiciones reales que afirman y denuncian su violación sistemática, producto de políticas y acciones fundamentadas en las formas de violencias y en el autoritarismo de muchos de los gobiernos de los países del área. En este contexto resulta importante indagar sobre la responsabilidad que tienen las Instituciones Educativas IE en cuanto a la defensa, el reconocimiento y el respeto de los Derechos Humanos DDHH.

Se plantea que a través del currículo oculto se vehiculizan una serie de violencias, que al no ser consideradas relevantes, crean el espacio propicio para la violación permanente de los DDHH en la medida que no se acepta ni respeta la diferencia, la otredad, la singularidad, creando un ambiente de atropello, abuso, inseguridad, incertidumbre, miedo, que afecta y pone en cuestión los logros señalados en los diferentes propósitos y principios de las IE.

En síntesis, la problemática que orienta y determina este artículo se concreta en el estudio, análisis, caracterización e intervención de los Derechos Humanos y sus implicaciones con las diversas formas de violencia escolar expresadas en el currículo oculto.
Análisis del plan de área de filosofía en la Institución Educativa San Vicente para su actualización
Authors: Rodríguez Sánchez Daniel Felipe
Published: October 2019

En la presente investigación se realizó un análisis de la planeación y del desarrollo curricular de las asignaturas de filosofía en la Institución Educativa San Vicente, ubicada en zona rural de La Plata-Huila. Se acompañó el análisis de una reflexión crítica acerca de las clases limitadas a la transmisión de conocimientos disciplinares, en este caso sobre la historia de la filosofía occidental. Se realizó también un cuestionamiento en relación con la metodología pedagógica tradicional basada en la exposición magistral y el método evaluativo convencional consistente en la elaboración de talleres y evaluaciones escritas que se limitan al pensamiento convergente. De forma coherente y pertinente se propuso un nuevo plan de área de filosofía que trascienda las caracterizadas prácticas pedagógicas tradicionales. Se partió de la autoevaluación del docente y del punto de vista de los estudiantes mediante una encuesta anónima estructurada y realización de plenarias; finalmente se reestructuró el plan de área de filosofía enfocado a la formación integral, fomentando el criticismo, la reflexión, el análisis racional, la deliberación y la capacidad propositiva en los educandos, mediante procesos estructurados de mediación, negociación, conciliación y concertación.
Educadores a pensar

Published: October 2019

Este artículo presenta los resultados de una investigación dirigida a determinar el conocimiento de un grupo representativo de estudiantes (116) de la Facultad de Educación de la Universidad Surcolombiana sobre el tema de abuso sexual infantil (A.S.I.). Estos estudiantes se encontraban en últimos semestres y realizando sus prácticas en instituciones educativas durante el segundo semestre de 2015. Por ser el tema tan amplio, se escudriñó suficiente información en estudios y teorías para determinar los parámetros de la encuesta que se les aplicó on line 51, diseñada por la propia investigadora. Con los resultados obtenidos se intentó, desde un diseño cuantitativo descriptivo, reflejar e interpretar el conocimiento o desconocimiento del tema de abuso sexual infantil en el área escolar por parte de universitarios que se están preparando para ser docentes. Se tuvieron en cuenta las siguientes variables: el concepto de abuso sexual infantil, la normatividad que rige actualmente en el Departamento y en el país, la ruta de atención necesaria para atender casos detectados en el aula y las prácticas que ha tenido el estudiante universitario con casos concretos de abuso sexual infantil. El proceso de recolección de datos tardó un tiempo considerable, pero se pudo determinar la apremiante necesidad de capacitar dicha población universitaria sobre abuso sexual infantil. Esto hizo pensar que hay que buscar la conversión de una universidad que sea reconocida por ser dinamizadora de procesos que protegen a los niños y niñas del abuso y el maltrato en la región surcolombiana.

Authors: Doss VA  , Sreeja Jeevan  , Madhumitha Paranjothi  , Dharaniyambigai Kuberapandian
Published: October 2019

Cardiac hypertrophy (CH) is a condition in which myocardial mass is increased beyond the normal range due to irreversible fibrotic events that lead to various complication like ventricular chamber dilation, thinning of the internal walls and extensive myocardial damage. In this study, the cardioprotective potential of the hydro-ethanolic extract of Piper betle (P. betle) was evaluated against cardiac hypertrophy induced by isoproterenol in male albino Wistar rats. Isoproterenol (10 mg/kg b.w., i.p., 7 days) induced cardiac hypertrophy in experimental rats which were simultaneously treated with the standard drug losartan (50 mg/ kg b.w., oral., 7 days) and hydro-ethanolic extract of P. betle (200 mg/kg b.w., oral., 7 days). Biochemical estimations revealed increased levels of glucose, protein, cholesterol, serum creatinine, cardiac maker enzymes (SGOT; SGPT and LDH), reduced enzymic antioxidants (SOD, CAT, GPx) and serum were observed during CH which were reciprocated to normal when treated with plant extract. Histopathological analysis of the heart tissue (left ventricles) showed repairment of cellular architecture with reduced stiffened cell layers and necrosis in plant extract administered rats thereby indicating the anti-hypertrophic potential of P. betle.

Published: October 2019

Every Industry has problems of effluent treatment. This can be revealed by the effective treatment of the effluent. The effective treatment can be done by using microorganisms to stabilize the organic and inorganic load of the effluent. The aim of the present work is to study the Industrial effluent microbiota and to identify some new active strains which can bring about fast biodegradation of the organic compounds. Studies were carried out to isolate the microorganisms from the collected effluent sample from the Industries of Bollaram, Hyderabad. An investigation was carried out to analyze Physicochemical parameters like Total suspended solids (TSS), Total dissolved solids (TDS), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) of untreated effluent and to degrade the effluent using native and non-native bacteria. The results of the parameters analysis revealed that untreated effluent was black in colour with an offensive odour. pH was alkaline with a high organic load such as TSS, TDS, BOD and COD which were higher than the permissible since the effluent had a high organic load, microbes (bacteria) present within the effluent was identified and isolated. The results of the study revealed the occurrence of Pseudomonas spp. And named as Pseudomonas auruginosa ES10. The presence of bacteria indicates the pollution status of the untreated tannery effluent, suggesting that it should be treated before its disposal using the biological method, particularly native and non-native bacteria for comparing their degrading efficiency. The results of the degradation study show that native bacteria Pseudomonas auruginosa ES10 was found to be very much successful in the reduction of toxic substances at the percentage range of 60-90% at different pH and incubation time, the bio-treated water can be reused for the agricultural and aqua-cultural purposes.

Published: October 2019

Prediabetes is a high-risk state for diabetes that is defined by glycaemic variables that are higher than normal but lower than diabetes thresholds. 5–10% of people per year with prediabetes will progress to diabetes, with the same proportion converting back to normal glycaemia. The prevalence of prediabetes is increasing worldwide, and experts have projected that more than 470 million people will have prediabetes by 2030. Prediabetes is associated with the simultaneous presence of insulin resistance and β-cell dysfunction abnormalities that start before glucose changes are detectable. Hence the present study to assess the risk factors of pre-diabetes risk among the adults in SMCH and to associate the prediabetic risk with demographic variables among adults. Quasi-experimental design was employed with 100 adults who met the inclusion criteria were selected by non-probability purposive sampling technique. The researcher collected the demographic variables and assessed the prediabetic risk among adults by using Indian diabetic risk score. The data analysis was done using descriptive and inferential statistics. The result shows that Out of 100 samples, 15(15%) is at low risk, 55(55%) is at moderate risk and 30(30%) is at high risk among adults. The mean and standard deviation of this study are 54.6 and 16.6, respectively, for adults. The association between the prediabetes risk and the demographic variable is statistically significant. The study reveals that the adults have a moderate risk for prediabetes which is analysed using Indian diabetic risk score.

Theoretical and Methodological Foundations of Designing a balance Model for Reproducing Investment Potential of Institutional Sectors in the Regional System
Authors: Naumov I. V.
Published: October 2019

Reproducing investment potential of institutional sectors of the economy of any territorial system becomes a challenging issue in the light of recent trends: lack of financial resources for modernization and development of the real sector of economy, failure to successful implementing the planned strategic programs for economic development of territorial systems at macroeconomic, regional and municipal levels. A systematic approach to the formation and reproduction of

these resources is required. In this regard, the main purpose of the work was to develop methodological foundations of designing a balance model for reproducing the investment potential of institutional sectors in the regional system. The analysis of the advantages and disadvantages of the existing approaches showed that a systematic representation of the reproduction processes of the investment potential of institutional sectors in the territorial systems requires a detailed mapping of the movement processes of financial resources between the sectors, as well as spatial features of the movement of their investment resources between the regional systems. Proposed in the work, the theoretical and methodological approach uses the basic principles of the system of national accounts: “double entry”, according to which one sector initiates the movement of financial flows, and the other accepts them; financial account structure of institutional sectors. Moran’s spatial autocorrelation and autoregression method was also applied. Thus, it provides to assess the investment resource endowment of the sectors and their sufficiency to solve the most important development problems, to determine the main uses of these resources by institutional sectors, and the riskiness of their investment activities. Such an approach provides an opportunity for state authorities and a financial regulator to assess the system of investment interconnections between institutional sectors that has developed in the regions, the problems and threats of financial development of these sectors, and to find reserves to solve them.
Disintegration of the World Trade System: Reasons and Consequences
Authors: Kuznetsov A. V.
Published: October 2019

The article presents the study results of the world trade stagnation issues associated with the WTO systemic crisis. The aim of the article is to summarize the main reasons for the world trade system disintegration and to identify feasible directions for the world economic order transformation. The G20 trade-restricting measures were analyzed based on the statistical databases of the WTO and the non-governmental organization Global Trade Alert (GTA). The views of leading domestic and foreign experts on the consequences of liberalization of the world trade in goods and services were summarized. The author systematized the reasons for the world trade system disintegration, including: the US anti-globalization policy aimed at containing the PRC; counteracting unipolar globalization by the Southeast Asian nations; developed countries’ rejecting the growing participation of developing countries in redistributing global resources; inefficiency of international organizations in solving problems of global imbalances, inequality and instability of the global financial system. Structuring disintegration processes revealed its main trends: protectionism, regionalism, trans-regionalism. There were shown mechanisms to keep the US in the European Union due to companies providing professional services to European business. The author evaluated Russia and China’s competitive advantages in the production chains of the new technological structure. The areas of cooperation between Russia and the BRICS countries for realizing export potential in agriculture, aviation and nuclear industries were determined. The prospects for trade and economic relations in Eurasia are discussed in terms of changing the economic paradigm and shifting the regulation of the global economy problems to the regional level.
ICD-data collection features: an international survey
Authors: Otero Varela Lucia , Doktorchik Chelsea , Wiebe Natalie , Eastwood Catherine , Quan Hude
Published: October 2019

Background:  The International Classification of Diseases (ICD) is globally used for coding morbidity and mortality statistics, however, its use, as well as the data collection features vary greatly across countries.

Objective: To characterize hospital ICD-coded data collection worldwide.

Methods: After an in-depth grey and academic literature review, an online survey was created to poll the 194 World Health Organization (WHO) member countries. Questions focused on hospital data collection systems and ICD-coded data features. The survey was distributed, using different methods, to potential participants that met the specific criteria, as well as organizations specialized in the topic, such as WHO Collaborating Centers (WHO-CC) or International Federation of Health Information Management Association (IFHIMA), to be forwarded to their representatives. Answers were analyzed using descriptive statistics.

Results: Data from 48 respondents from 26 different countries has been collected. Results reveal worldwide use of ICD, with variations in the maximum allowable coding fields for diagnoses and interventions. For instance, in some countries there is an unlimited number of coding fields (Netherlands, Thailand and Iran), as opposed to others with only 1-6 available (Guatemala or Mauritius). Disparities also exist in the definition of a main condition, as 60% of the countries use “reason for admission” and 40% utilize “resource use”. Additionally, the mandatory type of data fields in the hospital morbidity database (e.g. patient demographics, admission type, discharge disposition, diagnoses, …) differ among countries, with diagnosis timing and physician information being the least frequently required.

Conclusion: These survey data will establish the current state of ICD use internationally, which will ultimately be valuable to the WHO for the promotion of ICD and the rollout of ICD-11. Additionally, it will improve international comparisons of health data, and encourage further research on how to improve ICD coding.
Upregulation of spinal stretch reflexes during upper-limb posture control task
Authors: Miller Ryan Raymond , Cluff Tyler
Published: October 2019

Background: Sensory feedback from receptors in the eyes, skin, vestibular organs and muscles allows us to build accurate representations of the position and motion of our body within the environment. In unpredictable situations, such as when holding an umbrella in gusting winds, studies have suggested the nervous system upregulates the sensitivity of sensory organs to counter disturbances and increase the probability of success. To date, studies have focused exclusively on the upregulation of feedback mechanisms in the lower-limbs during standing balance. We know comparatively little about whether and how sensory upregulation contributes to the control of upper limb motor actions.

Objectives: Examine the upregulation and adaptation of upper limb muscle activity and spinal stretch reflexes when interacting with unpredictable mechanical environments.

Methods: Ten healthy, right-handed adults (age range: 20 – 27 years) performed a postural control task where the goal was to maintain their hand within a fixed target. Participants performed the task while seated with their arm supported in an exoskeleton robot that can sense and disturb arm motion. They received real-time feedback of their movements on a virtual reality system. The protocol was delivered in three phases. The baseline phase consisted of 50 trials where subjects maintained their hand in the target in the absence of mechanical disturbances. Subjects then performed a peri-exposure phase that consisted of 100 null trials (no forces applied), 100 step-torque perturbations that produced rapid elbow flexion (+2Nm), and 100 perturbations that caused rapid elbow extension (-2Nm). We then unexpectedly removed the perturbations and subjects performed 75 trials to determine whether muscle activity returned to baseline levels. Kinematics and muscle activity were recorded throughout the experiment.

Results: Preliminary results show that background muscle activity and spinal stretch reflexes were the largest when first exposed to unpredictable mechanical perturbations and adapted systematically with repeated exposure.

Conclusions: Similar to results observed in the lower-limbs during standing balance experiments, we observed upregulation of background muscle activity and spinal stretch reflexes when interacting with unpredictable mechanical environments with the upper-limb. The amplitude of spinal stretch responses and background muscle activity decayed systematically with repeated exposure to unpredictable mechanical perturbations.
Developing an app to provide physical and mental health benefits for menopausal women
Authors: Shah Prachi , Stroulia Eleni , Ross Sue , Sydora Beate
Published: October 2019

Background: Menopause is the end of a women’s menstrual cycle and reproductive years. For some women the transition is without major problems; others struggle with various psychological and physical symptoms. Regular walking exercise can be an easy way to maintain physical and mental health. Previous focus groups revealed that women enjoy and want the social aspect of walking groups. 

 

Objectives: The goal of this study is to test use and effectiveness of a walking app platform specific for menopausal women that allows them to connect with each other to schedule walks in Edmonton, and track the effect of walking on their symptom changes.

 

Methods: Women will be recruited from the Edmonton Menopause clinics and by word of mouth. Interested and consented women receive login information to use the app to schedule and sign-up for walks. Women will complete menopause-specific QOL and symptom questionnaires at their first login and will be prompted to complete them monthly thereafter. Women will also be asked to record their walking durations and intensities. Participating women will be invited to focus groups to discuss their experience using the app. Descriptive statistics will be applied to analyze data collected at the backend from questionnaires and surveys, and qualitative content analysis will be applied to analyze the audio-recorded focus groups. 

 

Results: A prototypic online application has been created including a user manual.

Access is restricted and all potential participants will be screened after their first login by the research team prior to gaining full access. Women will then be able to use the app features for schedules and surveys. Data collected at the back end by the researchers will determine the use and effectiveness of the app and explore the impact of social walking on menopause symptom changes.

 

Conclusion: This is the first social platform of this kind created specifically for menopausal women. Ultimately we hope that this platform will empower women to seek lifestyle changes such as walking exercises and connect with each other on the communality of menopause. Testing the use and effectiveness of the app will help us to improve and further develop the app.

Published: October 2019

Este artigo tem origem na pesquisa realizada no âmbito de Mestrado em Educação, concluída no início de 2013. Teve como objetivo central identificar e discutir elementos do imaginário tecnológico partilhado por professores, tendo em vista analisar como este atravessa as práticas pedagógicas e as relações que os docentes estabelecem com os alunos, no contexto da cultura digital. A partir desse escopo mais geral e tendo por base as teorias da cultura digital e do mito da digitalização, pretendeu-se abordar a percepção que professores têm da atividade docente diante das supostas mudanças pelas quais vem passando a profissão, em tempos de massificação do acesso às tecnologias digitais.  A pesquisa, de caráter qualitativo, teve por base a realização de entrevistas individuais semiestruturadas, seguindo a lógica do sistema de rede para a seleção dos entrevistados. Para tanto, foram entrevistados quinze professores de Ensino Médio atuantes, em sua maioria, em escolas estaduais de formação docente, situadas na cidade do Estado do Rio de Janeiro. Os resultados indicam que o imaginário tecnológico vivenciado por estes profissionais apresenta aspectos do mito da cultura digital, no interior do qual prevalece a impressão de que há um maior afastamento entre gerações e a concepção de que os jovens são experts no uso de tecnologias, frente a adultos pouco qualificados nesse âmbito Palavras-chave: Professores.

Authors: von Davier Matthias , Khorramdel Lale , He Qiwei , Shin Hyo Jeong , Chen Haiwen
Published: October 2019

International large-scale assessments (ILSAs) transitioned from paper-based assessments to computer-based assessments (CBAs) facilitating the use of new item types and more effective data collection tools. This allows implementation of more complex test designs and to collect process and response time (RT) data. These new data types can be used to improve data quality and the accuracy of test scores obtained through latent regression (population) models. However, the move to a CBA also poses challenges for comparability and trend measurement, one of the major goals in ISLAs. We provide an overview of current methods used in ILSAs to examine and assure the comparability of data across different assessment modes and methods that improve the accuracy of test scores by making use of new data types provided by a CBA.

The results of investigations on studying of the impact of agromeasures at the functioning of microbial communities in chernozem typical has been shown. The aim of article was a comparative analysis of the functioning of bacterial and fungal microbiota in sugar beet rhizosphere at the application of biological and intensive (industrial) agrarian systems during culture ontogenesis. We applied a microbial (identification of microorganism’s number and their qualitative composition), ecological (ecological index calculation), biochemical (estimation of the microbial biomass and metabolic coefficient) and statistical (establishing the results probability) research methods is to achieve of this purpose.

The application of agromeasures are significant impact on microbial communities in chernozem typical in sugar beet rhizosphere during ontogeny and are caused the change of trophic relationships and different direction of microbial processes in soil has been established. The phase of plant development is also had a significant impact on the activity of soil microorganisms functioning. The number of root exudates is increased and plant debrises are accumulated in the soil during sugar beet ontogeny. It is promotes to the growth of numbers, biomass and diversity of microbial communities’ in chernozem typical and consequently intensification of soil organic matter transformation. Thus the application of biological agrarian system compared to intensive is helped to optimization of soil microbial complex. It is accompanied the increasing of the number, diversity and content of microbial biomass and growth of microbial groups resistance. This helps to enhance of microbial transformation of organic matter and improve of soil trophic metabolic profile. The use of intensive agrarian system are involved the reducing of the number, diversity and biomass of microorganisms, that accompanied by a simplification of trophic relationships and deregulation of plant-microbe systems.

Established the results of studies of crop photosynthetic characteristics and formation performance of winter rape. The aim of our research was to study the influence of sowing seeds and seeding rates on photosynthetic activity and productivity agrophytocenoses forming hybrid rape. The study was conducted in 2009-2014. In the stationary field experiment at the National University of Life and Environmental Sciences of Ukraine»Agronomic Research Station» and in the laboratory analytical research department of crop National University of Life and Environmental Sciences of Ukraine. 

During the studies used conventional methods for research in agronomy. The subject of research were hybrids of winter rapeseed firm Syngenta NKTechnikandNK Petrol. The technology used – is common to forest steppe zones except investigated elements. Predecessor – winter wheat. The rate of mineral fertilizers – N30P60K105 + N30 + N30.

The scheme of the experiment was supposed to study the following factors: Factor A – hybrids; Factor B – sowing; Factor C – seeding norms.

The highest leaf surface area of hybrids formed in period BBCH 62-65 in a variant of normal seeding 0,6 million germinated seeds per 1 ha and sowing 20-25 August.

The greatest weight of dry matter (13.23 t/ha) formed hybrid plants in NK Petrol variant of 20-25 August sow­ ing and seeding rate 0.6 milliongerminated seeds per 1 ha. Compared to the 25-30 August and sowing seed rate of 0.4 milliongerminated seeds per 1 hectare increase of 1.8 t/ha.

The highest seed yield an average of 5 years formed agrophytocenoses winter rapeseed sowing NK Petrol on 20-25 August and Calibration 0.6 milliongerminated seeds per1 hectare – 4.24 t/ha, which is more of a control option for the same period to 0.28 t/ha.

Today in the world there are many varieties of potatoes which differ as the duration of the growing season and other characteristics. Thus, in the State Register of plant varieties suitable for distribution in Ukraine in 2016 were registered 150 varieties of potatoes, which belong to five groups of ripeness. There is a close link between period of the growing season, weather conditions potato cultivation and accumulation of reserve substances, harvest, struc­ ture of harvest, marketability [1, 2]. Therefore, the aim of our research was to determine the influence of meteoro­ logical conditions, groups of ripeness on formation economic characteristics of potato tubers.

In our studies used potato tubers which apply to two groups of ripeness: medium-early (Satina (standard), Red Lady and Mozart) and medium-ripe (Arosa (standard), Sifra). Potatoes were grown during 2012-2014 years in conditions of “Bioteh Ltd” (Kiev region Boryspil district Gorodyshche village), which is in a zone Forest Steppe of Ukraine.

Weather conditions in vegetation periods 2013 and 2014 compared with 2012 were the better that promoted ob­ tain higher harvest of potato tubers. On the average during three years of studies high harvest observed in the group of medium-ripe (41.1 t/ha) as opposed to 33.5 t/ha in the medium-early group.

The analysis of potato harvest showed that the most suitable for processing French Fries are varieties Satin which dominated tubers with coarse fraction (over 55 grams) – 50.4 % from total weight and partially – Arosa (30.7% in this fraction). Other varieties had the largest part in the fraction 45-55 grams (Red Lady – 57.2%; Mozart – 42.8%, Arosa – 41.5%; Sifra – 41.6%) and are therefore suitable for processing into Chips.

Research marketability of harvest showed that the best result for this indicator in both groups of ripeness ob­ tained in control variants: 75.2-75.3% in the medium-early and 77.9 % in the medium-ripe.

The analysis of the significance of correlations ties between the yield of winter wheat (2012), soybean (2013), spring wheat (2014), buckwheat (2015) and the under indicators of quantity of microorganisms of some of ecology-trophic, functional and taxonomic groups, their of physiological and biochemical activity, the indicators of intensity processes of mineralization, the phytotoxicity, the stability of microbial communities for the four of seasons of vegetations it was conducted. It is established that the effective fertility of grey forest soils significantly (r = 0,666-0,999) positively correlated with the quantity of ammonificators; with immobilization of mineral nitrogen, oligonitrophillouses, cellulose decompose; with of autochthonous microorganisms; with total number of microorganisms (r = 0,684); with total biological activity (r = 0,764); with probability of forming of colonies denitrification (PFC); with of pH of salt and pH of water; with capacity in soil of nitrogen, potassium, phosphorus, humus. The yield of agricultural crops negatively correlated significantly with the number melaninsyntezuvalnyh Micromycetes (r = - 0,665) and with their specific contents in the total number of micromycetes (r = - 0,673), with the indicators of phytotoxicity (r = - 0,648), with the hydrolytic acidity, with the total exchange acidity and content of mobile aluminium.Direct correlation of medium significance level (r = 0,333-0,665) is observed between the effective fertility of grey forest soils and a quantity denitrifications, pedotrofov, of polisaharidnay microorganisms, actinomycetes, micromycetes, mobilizers of mineral phosphates, acid-forming microorganisms, PFC nitrifiers, of autochthonous, of cellulose-decomposing bacteria, with humus mineralization activity (r = 0,564), the content of nitrate nitrogen and of ammonium nitrogen, the phosphorus degree of mobility. Feedback of medium level of significance observed between the yield and PFC olihotrofnosti, index of pedotrofnosti. The relationship between yield and coefficient of nitrogen mineralization by average multi-year data was insignificant (r = 0,090).

For the first time shown that an effective fertility of gray forest soils correlated with stability of microbial groupings, which is described of the quantity of significancy of correlation ties between their components.
