The authors of the article identified four basic functions of the use of information technology in the course of training future representatives of a profession: information and training, forming, evaluation and correction, research.  It is noted that these functions do not operate separately, but as elements of a single system, depending on the conditions determined by the features of the information EE. The analysis allows the authors of the article to assert that at this stage of the educational process evolution the main task is to create a methodology related to the use of information management technologies in the development of electronic materials of educational nature and their implementation in the context of pedagogical activity.Los autores del artículo identificaron cuatro funciones básicas del uso de la tecnología de la información en el curso de la capacitación de futuros representantes de una profesión: información y capacitación, formación, evaluación y corrección, investigación.

Seasonal Dynamics of Fruit Flies (Diptera: Drosophilidae) in Forests of the European Russia

(1) Background: Seasonal dynamics of the abundance and species diversity of various insect groups is of great importance for understanding their life cycles; (2) Methods: In our study, Drosophilidae species and their seasonal changes in Mordovia State Nature Reserve were explored. We collected the flies by crown fermental traps in five types of forests (birch, aspen, linden, pine and oak) since May to October in 2019. (3) Results: A total of 4725 individuals belonging to 9 genera and 30 species of drosophilid flies were identified, among them 15 species in 3 genera are new to the Republic of Mordovia. Drosophila obscura and D. histrio were the most abundant species in traps, the other mass species are D. kuntzei, D. testacea, D. phalerata, S. rufifrons, D. bifasciata, A. semivirgo, and L. quinquemaculata. (4) Conclusions: We found three groups of mass species with significant correlation of seasonal dynamics, e.g., D.obscura and D. bifasciata; D. histrio, D. kuntzei, D. phalerata, and D. testacea, and, finally, A. semivirgo and S. rufifrons. Apparently, the similarity observed in the seasonal dynamics of these drosophilid species is influenced at a high degree by their food preferences and rearing sites

Post-fire insect fauna explored by crown fermental traps in forests of the European Russia

Wildfires considerably affect forest ecosystems. However, there is a lack of data on the post-fire status of insect communities in these ecosystems. This paper presents results of a study conducted in 2019 which considered the post-fire status of the insect fauna in a Protected Area, Mordovia State Nature Reserve (Republic of Mordovia, centre of European Russia), considered as regional hotspot of insect diversity in Mordovia. We sampled insects on intact (unburned, control) and fire-damaged (burnt in 2010) sites and compared the alpha-diversity between sites. In total, we sampled and analysed 16,861 specimens belonging to 11 insect orders, 51 families and 190 species. The largest orders represented in the samples were Coleoptera (95 species), Diptera (54 species), Hymenoptera (21 species), and Neuroptera (11 species). Other insect orders were represented by between one and four species. The largest four orders (Coleoptera, Lepidoptera, Diptera and Hymenoptera) represented 96.7% of all studied specimens. We found that in the ninth year after low intensity surface fire damage, the insect diversity had returned to a similar level to that of the control (unburned) sites. Sites damaged by crown wildfire differed considerably from other sites in terms of a negative impact on both species diversity and the number of specimens. This indicates the serious effect of the crown fires on the biodiversity and consequent long-term recovery of the damaged ecosystem

PROGNOSTIC SIGNIFICANCE OF POSITRON EMISSION TOMOGRAPHY IN AUTOLOGOUS STEM CELL TRANSPLANTATION FOR NON-HODGKIN’S LYMPHOMA

Objective: evaluation and comparison of positron emission tomography (PET) prognostic value with other predictors of effectiveness in patients with non-Hodgkin’s lymphoma (NHL) receiving high-dose chemotherapy with autologous hematopoietic stem cell transplantation (AHSCT).Materials and methods. The retrospective data on 49 consecutive patients with NHL  receiving high-dose chemotherapy with АHSCT was               analyzed. The median age was 36.2 (7–60)  years. Median follow-up is currently 24 (1–82)  months. Prognostic factors analyzed included sex, response to the initial chemotherapy, time to relapse, second-line chemotherapy regimen type, B-symptoms on relapse, serum lactate dehydrogenase and albumin levels, response assessed by computer tomography (CT), number of chemotherapy lines, condition regimen, PET-scan results before (PET1, n = 49) and after (PET2, n = 39) AHSCT.Results. Two-year overall and event-free survivals were 74.4 and 79.1 %, respectively. Patients with CT-confirmed progression prior to AH-SCT had the worse prognosis. Prognostic significance of PET-status  was shown in chemosensitive patients (partial/complete response).The overall survival in PET1-negative and PET1-positive patients were 95.4 vs 71.0 % (р = 0.019), respectively. In PET2-positive and PET2-negative patients the overall and event-free survivals were 59.8 vs 100 % (р = 0.001) and 54.4 vs 94.4 % (р = 0.02), respectively.     In combined analysis of PET1 and PET2 statuses prognostic significance of PET2 prevailed over PET1 results significance. The multivariate analysis confirmed only PET1 significance for survival prediction.   Conclusion. Chemosensitivity of the tumor, assessed by CT, is the most important prognostic factor. In chemosensitive patients achievement PET1 or PET2 negativity means better prognosis. The patients with PET positivity prior and after AHSCT have the worst prognosis
