Realization of Didactic Principle of Accounting Native Language in Textbooks for Tajik School

Описано состояние лингводидактической теории в Республике Таджикистан, имевшее место после обретения республикой независимости. Произведен сопоставительный анализ действующих учебников русского языка для средних общеобразовательных школ с таджикским языком обучения, составленных в первые годы XXI в. таджикскими методистами.The article describes the state of lingual and didactic theory inthe Republic of Tajikistan which took place after the republic acquired independence. A comparable analysis of existing Russian language textbooks for secondary schools with the Tajik language of teaching compiled by Tajik methodologists taking into account the principles of teaching the native language (based on the competence approach) in the early years of the XXI century is carried out. In the analyzed textbooks of the Russian language the ways of organizing didactic material are considered: texts and assignments for them, semanticized vocabulary, formation of lexical and grammatical skills, agreement and government skills and types of communicative tasks

Development Problems of Educational and Methodological Manuals on the Russian Language for School and Univer

Рассматриваются методологические, логические и содержательные связи между учебниками русского языка для средних общеобразовательных учреждений с таджикским языком обучения и учебниками методики преподавания русского языка для студентов — будущих учителей русского языка в таджикской школе. Учитываются объективно существующие трудности обучения студентов, которые заключаются в том, что языковая / речевая подготовка студентов на русском языке далеко не всегда соответствует требованиям образовательного стандарта, что вызывает определённые трудности в обучении специальным дисциплинам в педагогическом вузе.The author examines methodological, logical and meaningful links between textbooks of the Russian language for secondary educational schools and the Tajik language of instruction and textbooks, methods of teaching the Russian language for students – future teachers of the Russian language in the Tajik school. Objectively existing difficulties of teaching students are taken into account, which consist in the fact that the language/ speech training of students in Russian does not always meet the requirements of the educational standard, which causes some difficulties in teaching special subjects at the Pedagogical University

Influence of water deficit on photosynthetic activity, dry matter partitioning and grain yield of different durum and bread wheat genotypes

We aimed to study the influence of soil water deficit on gas exchange parameters, dry matter partitioning in leaves, stem and spike and grain yield of durum (Triticum durum Desf.) and bread (Triticum aestivum L.) wheat genotypes in the 2013–2014 and 2014–2015 growing seasons. Water stress caused reduction of stomatal conductance, photosynthesis rate, transpiration rate, an increase of intercellular CO2 concentration. Photosynthesis rate positively correlated with growth rate of genotypes. Drought stress caused adaptive changes in dry matter partitioning between leaves, stem and spike of wheat genotypes. Stem dry mass increased until kernel ripening. Drought stress accelerated dry mass reduction in leaves and stem. High growth rate of spike dry mass was revealed in genotypes with late heading time. Spike dry mass positively correlated with photosynthesis rate and grain yield. Generally, bread wheat is more productive and tolerant to drought stress than durum wheat

Literary Text in an Integrated Lesson of the Russian Language in a Tajik school

The problem of the use of literary texts in integrated lessons of the Russian language and literature, caused by the events of the 90s, is considered, which is important for the linguodidactics of Tajikistan. In the twentieth century, when reading lessons in Russian and Russian literature were removed from the curriculum of secondary schools, Russian language textbooks were not published. The article analyzes the possibility of publishing manuals that allow not to lose touch with Russian classical literature, its enormous cultural, educational and educational potential for students in grades 7-11. It is shown with a specific example how a literary text can be used in a Tajik school in a Russian language lesson, built taking into account the requirements of a competence-based approachРассмотрена важная для лингводидактики Таджикистана проблема использования художественных текстов на интегрированных уроках русского языка и литературы, вызванная событиями 90-х гг. ХХ в., когда из учебного плана средней школы были изъяты уроки чтения на русском языке и русской литературы, не издавались учебники русского языка. Проанализирована возможность издания пособий, позволяющих не утерять связь с русской классической литературой, ее огромным культурным, образовательным и воспитательным потенциалом для учеников 7–11 х классов. Показано на конкретном примере, каким образом в таджикской школе может быть использован художественный текст на уроке русского языка, построенном с учетом требований компетентностного подход

Secondary Prevention and Quality of Life of Patients with Stable Coronary Heart Disease

Aim. To assess the quality of life of patients with stable coronary heart disease (CHD) initially and 12 months after drug and non-drug secondary prophylaxis according to clinical guidelines.Material and methods. 73 patients (57 men, 16 women) with confirmed stable coronary artery disease were included in the study, of which 44 patients described a clinic for angina pectoris of functional class I-IV. The study included 2 patient visits: an initial treatment visit (V0) and a repeat visit after 12 months (V2). At both visits, blood pressure (BP), low-density lipoprotein cholesterol (LDL-c), quality of life (QL) were assessed using SAQ (Seattle Angina Questionnaire), drug therapy. Compliance with 5 basic principles of prevention was also assessed, which included: (1) healthy lifestyle (healthy lifestyle) (rejection of bad habits (smoking), moderate physical activity, lowcholesterol and low-carb diet); (2) normalization of body weight; (3) optimal drug therapy (the frequency of taking medications was evaluated using the original questionnaire); (4) achievement of target values of LDL-c in the entire group; (5) blood pressure in hypertensive patients. During V0, if necessary, drug therapy was adjusted in accordance with clinical recommendations. During V2, 57 patients (47 men and 10 women) were examined. The response was 80.8%.Results. After 12 months of follow-up, a statistically significant improvement in exercise tolerance (p=0.003), angina stability index (p=0.045) and the frequency of stress angina attacks (p=0.003) was noted when assessing the median of QL indicators. After 12 months of follow-up, 59% of patients used optimal drug therapy, including 4 drugs according to clinical guidelines. A healthy lifestyle (regular physical activity and smoking cessation) was achieved in 20.4% after 12 months of follow-up, the target level of LDL-c ˂ 1.8 mmol/L was achieved in 44.5% of patients, and the target blood pressure was achieved in 74,6%. The achievement of all 5 principles of secondary prevention of coronary heart disease according to the results of the work carried out by the visit after 12 months of follow-up was revealed only in 7% of patients (4 patients), and the implementation of 4 principles of prevention was noted in a quarter of patients from the group (24.5%, n=14).Conclusions. With drug and non-drug secondary prevention of coronary heart disease in patients with stable CHD after a year of follow-up, a statistically significant increase in QL indicators was noted due to increased exercise tolerance and a decrease in the frequency of angina attacks. Nevertheless, the basic principles of prevention were fully implemented only in 7% of patients

Tukezban Huseynova,1 Farah Abdulaliyeva,2 Michele Lanza3 1Briz-L Eye Clinic, 2National Ophthalmology Center, Baku, Azerbaijan; 3Second University of Naples, Caserta, Campania, Italy Purpose: To compare the keratometric and pachymetric parameters of healthy eyes with those affected by steep cornea and keratoconus (KC) using Scheimpflug camera.Setting: Briz-L Eye Clinic, Baku, Azerbaijan.Design: A cross-sectional study.Methods: In this study, 49 KC (Amsler–Krumeich stage 1) eyes and 36 healthy eyes were enrolled. A complete ophthalmic evaluation and a Scheimpflug camera scan were performed in every eye included in the study. Tomographic parameters such as parameters from the front and back cornea, maximum keratometry reading (Kmax), corneal volume (CV), anterior chamber volume (ChV), anterior chamber depth (ACD), anterior chamber angle (AC angle), keratometric power deviation (KPD), maximum front elevation (Max FE), and maximum back elevation (Max BE), as well as pachymetric progression indices (PPI), Ambrosio relational thickness (ART), index of surface variance (ISV), index of vertical asymmetry (IVA), center keratoconus index (CKI), index of height asymmetry (IHA), index of height decentration (IHD), and radius minimum (RM) were collected and statistically compared between the two groups.Results: PPI, ART, ISV, IVA, CKI, IHA, IHD, and RM parameter values were significantly different (P<0.05) between the KC and healthy eyes. There were no significant differences in K mean and Q values of the frontal corneal parameters, as well as in Kmax, AC angle, RM, back, and front astigmatism, between stage 1 keratoconic and normal Caucasian eyes with steep cornea. All other parameters such as K mean and Q values of the back corneal parameters, Max FE, Max BE, ACD, ChV, and CV showed significant differences between the groups (P<0.05 for all). Conclusion: Scheimpflug imaging is able to detect corneal morphological differences between stage 1 KC eyes and healthy eyes with steep cornea, in Caucasians.
