Published: December 2020

The article deals with the problem of psychological mechanisms of development of students’ mathematical research abilities in the process of solving mathematical creative tasks. It is indicated on the growing role of mathematical knowledge in connection with the implementation of a new, broader approach to the social functions of the school. Therefore, the formation of creative, research thinking, high level of need for achievements of schoolchildren is, of course, an important task of modern education, in particular its intermediate level. In order to develop the flexibility of thinking, developed and proposed to students of the upper classes, three types of problems with gradually increasing complexity: analytical and synthetic problems, problems with different degrees of assistance, tasks of self-research orientation. The results of recent researches and publications on psychology of creative activity, specifics of the process of formation of mathematical abilities are analyzed. The definition of concepts of research abilities, research mathematical abilities is given. The relationship between research abilities and the development of the problem of creativity psychology has been established. It was created the methodology for the development of components of mathematical research abilities of pupils in the process of carrying out special classes, which was focused on the development of separate components of mathematical research abilities. It has been confirmed that specially organized training positively influenced the development of structural components of mathematical research abilities of senior pupils. It is indicated on certain differences in the definition of research abilities in psychological and pedagogical literature, in revealing the essence, structure of research abilities, which affects the absence of valid methods of their detection. This is precisely why we can explain the inadequate development of this problem in methodological, theoretical and practical plans. It is proved that the senior school age is the age of development of the pre-professional scientific orientation of the person, in particular research abilities. The research mathematical orientation of high school students is manifested in the ability to quickly and easily find original, non-standard ways of solving problems, to investigate problems for compatibility and sufficiency of data, to establish cause and effect patterns. It is confirmed that the role of the motivational-personal component of mathematical research abilities is increasing among the high school students, namely: the interest in mathematical thinking is increasing, the desire to learn new is growing, showing persistence, determination, commitment and so on.

Published: December 2020

Field experiments were conducted in three Agroecological zones (AEZ) at Farmer’s field, Rangpur (AEZ-3), Farmer’s field, Ishurdi (AEZ-11) and BINA farm, Mymensingh (AEZ-9) to investigate the integrated effect of vermicompost and chemical fertilizers (CF) on Mustard (Brassica napus L.) during 2017-18 cropping season to reduce the usage of chemical fertilizer for mustard cultivation. The experiments were carried out with eight treatments and three replications in Randomized Complete Block Design. The treatments for the crops used in the experiments were T1: Native soil fertility, T2:100% chemical fertilizer (CF),T3: 75% CF, T4: 75% CF + Vermicompost (VC) @ 4 t ha-1, T5:85% CF ,T6: 85% CF + VC @ 4 t ha-1 T7: 75% CF +VC @ 2 t ha-1­­­­ and T8: 85% CF+VC @ 2 tha-1. Fertilizers applied on the basis of soil test (STB). Application of vermicompost with chemical fertilizer increased the yield attributes and yields of mustard. The treatment T6 (85% CF + VC @ 4 tha-1) gave the tallest plant height, greatest number of pods plant-1 and siliqua pod-1 and maximum seed (1.82, 1.26 and 1.49 t ha-1 at Rangpur, Ishurdi and Mymensingh, respectively) and straw yields of mustard at all the location with the few exception. But the treatment T6 gave the identical results with the treatments T8, T4 and T2. Application of vermicompost also increased the N, P and K uptakes of mustard at all the location. The treatments T6 T8 and T4 gave statistically identical nutrients uptakes to the treatment T2 (100%CF). The results revealed that 75% CF with 4 t ha-1 vermicompost or 85% CF with 2 t ha-1 vermicompost almost equally effective to produce seed yield of mustard which was also comparable with the full dose (100%) of chemical fertilizers (NPKS) in all the location. Therefore 15-25% chemical fertilizer (NPKS) could be reduced either with the application of 75% CF with 4 t ha-1 vermicompost or 85% CF with 2 t ha-1 vermicompost for mustard cultivation.

Silicone oil: physical properties and clinical use (a literature review)
Authors: Tashmukhamedov A. A. 
Published: December 2020

Introduction. In modern vitreoretinal surgery, silicone oil is used for replacing the vitreous body during vitrectomy. This surgery is performed to treat retinal detachment, proliferative retinopathy, giant retinal tears and severe eye injuries. In this regard, it seems especially relevant to provide a description of the physical characteristics of silicone oils that determine the choice of surgeons.Purpose. To study indications for the use of silicone oil tamponade as well as possible complications associated with its use based on a literature review and own research.Materials and methods. We analyzed literature on PubMed, eLibrary, and Medline over the past 30 years. Overall, 34 sources of literature were reviewed, including results of our own clinical studies.Results. Literature review has shown that silicone oils are very useful as a permanent tamponade. Although gas tamponade can be used for giant retinal tear management, silicone oils are used for minimizing the risk of post-surgical bleeding and reattach detached retinas in case of severe eye injuries. One of the main issues related to the use of silicone oils is the post-surgical increase in IOP. To reduce the risk of such complication, we have proposed methods of infusion and optimal schedule of silicone oil removal.Conclusion. Silicone oil is the optimal choice for treating most retinal diseases and improving their prognosis. An important criterion for choice of silicone oil is the time that is required for tamponade.

AIM: to analyze basic medical care characteristics for hemorrhoidal disease (HD) in federal subjects of Russia in 2018.MATERIALS AND METHODS: the study is based on the summary data of the annual statistical observation form «Report of the chief coloproctologist of the subject of the Russian Federation» for 2018, which includes the level of outpatient treatment for HD per 100,000 of the population, the number of outpatient coloproctologists, the number of hospitalized patients for HD, the rate of patients hospitalized for emergency indications and number of coloproctological beds.RESULTS: in 2018 in Russia there were 304.9 outpatient visits per 100,000 thousand of the population for HD (Me=304.9; Q1=236.1; Q3=401.2). Number of coloproctologists was 0.23 per 100,000 (Me=0.23; Q1=0.13; Q3=0.32), and no correlation between these indicators was found (r=0.18; p=0.09). The hospitalization rate for HD was 36.8 (Me=36.8; Q1=30.5; Q3=44.7). There were 2.68 coloproctological beds per 100,000 (Me=2.68; Q1=1.95; Q3=3.35), and the percentage of patients with HD hospitalized in an emergency hospital was 34.0% (Me=34.0; Q1=24.0; Q3=45.0). There was no correlation between the number of patients treated in a hospital and the proportion of emergency hospitalizations in patients with hemorrhoids (r=0.1; p=0.38).CONCLUSION: in 2018, at least half a million patients with HD have got an outpatient consultation of coloproctologist. A significant staff shortage in specialists remains, and unresolved organizational problems require further studies.

AIM: to compare multiparametric endorectal ultrasound (ERUS) and enhanced imaging colonoscopy in the diagnosis of early colorectal cancer.PATIENTS AND METHODS: the study included 78 patients with epithelial rectal tumor. All the patients underwent multiparametric ERUS and colonoscopy with examination by narrow beam imaging (NBI) at optical magnification. All the patients were operated.RESULTS: a morphological examination removed specimens revealed adenomas in 48 cases, in 19 specimens – adenocarcinomas in situ and T1, and in 11 specimens – adenocarcinomas with invasion of the muscle layer or deeper. When calculating the accuracy indicators of diagnostic methods for groups of patients with adenoma, Tis-T1 adenocarcinoma, and T2-T3 adenocarcinoma, the difference in the sensitivity and specificity of the methods in none of the presented groups did not reach the level of statistical significance (p>0.05).ROC analysis showed that ultrasound has a prognostic value comparable to colonoscopy. The area difference was 0.013 (p=0.85).CONCLUSION: endoscopy and ultrasound have similar value in the diagnosis of malignant transformation of rectal adenomas.

BackgroundCommunity-acquired pneumonia (CAP) is an essential consideration in patients presenting to primary care with respiratory symptoms; however, accurate diagnosis is difficult when clinical and radiological examinations are not possible, such as during telehealth consultations.AimTo develop and test a smartphone-based algorithm for diagnosing CAP without need for clinical examination or radiological inputs.Design and settingA prospective cohort study using data from participants aged >12 years presenting with acute respiratory symptoms to a hospital in Western Australia.MethodFive cough audio-segments were recorded and four patient-reported symptoms (fever, acute cough, productive cough, and age) were analysed by the smartphone-based algorithm to generate an immediate diagnostic output for CAP. Independent cohorts were recruited to train and test the accuracy of the algorithm. Diagnostic agreement was calculated against the confirmed discharge diagnosis of CAP by specialist physicians. Specialist radiologists reported medical imaging.ResultsThe smartphone-based algorithm had high percentage agreement (PA) with the clinical diagnosis of CAP in the total cohort (n = 322, positive PA [PPA] = 86.2%, negative PA [NPA] = 86.5%, area under the receiver operating characteristic curve [AUC] = 0.95); in participants 22–<65 years (n = 192, PPA = 85.7%, NPA = 87.0%, AUC = 0.94), and in participants aged ≥65 years (n = 86, PPA = 85.7%, NPA = 87.5%, AUC = 0.94). Agreement was preserved across CAP severity: 85.1% (n = 80/94) of participants with CRB-65 scores 1 or 2, and 87.7% (n = 57/65) with a score of 0, were correctly diagnosed by the algorithm.ConclusionThe algorithm provides rapid and accurate diagnosis of CAP. It offers improved accuracy over current protocols when clinical evaluation is difficult. It provides increased capabilities for primary and acute care, including telehealth services, required during the COVID-19 pandemic.

Pencemaran lingkungan hidup tidak hanya berdampak buruk bagi kehidupan masyarakat yang ada sekarang namun juga akan mengancam kelangsungan hidupnya kelak. Adanya pencemaran lingkungan yang ditimbulkan dari adanya pembuangan limbah ke sungai yang berulang membuat perlunya ada penegakan sanksi pidana yang didasarkan pada UUPPLH. Kasus yang diangkat dalam penelitian ini adalah kasus pencemaran air di sungai Klampisan oleh PT. Marimas pada tahun 2013 yang berdampak pada warga di sekitar sungai Klampisan.
Penelitian ini bertujuan untuk menjelaskan penegakan sanksi pidana dalam pencemaran lingkungan hidup ditinjau dari UUPPLH dan menjelaskan hambatan dalam penegakan sanksi pidana dalam pencemaran lingkungan hidup ditinjau dari UUPPLH.
Penelitian ini menggunakan metode pendekatan yuridis normatif. Spesifikasi penelitian ini adalah deskriptif analitis yaitu menggambarkan peraturan perundang – undangan yang berlaku dikaitkan dengan teori – teori hukum dan praktek pelaksanaan hukum yang menyangkut permasalahan tersebut. Metode analisis data menggunakan cara deskriptif kualitatif
PT. Marimas, Semarang belum dikenakan sanksi pidana atas pencemaran sungai Klampisan yang diakibatkan karena kurangnya alat bukti dalam pembuktian pencemaran lingkungan sehingga penegakan sanksi pidana dalam pencemaran lingkungan hidup ditinjau dari UUPPLH di PT. Marimas, Semarang belum berjalan. Hambatan dalam penegakan sanksi pidana dalam pencemaran lingkungan hidup ditinjau dari UUPPLH di PT. Marimas, Semarang adalah kurangnya sosialiasi kepada masyarakat terkait hukum lingkungan, kendala dalam pembuktian karena di sepanjang Kali Klampisan terdapat sekitar 7 industri yang punya andil membuang limbah ke badan sungai tersebut dan pembangunan instalasi Pengelolaan Air Minum (PAM) di wilayah Purwoyoso, dan belum maksimalnya infrastruktur penegakan hukum yang disebabkan oleh kurangnya ketegasan dalam pelaksanaan peraturan perundangan dan sumber daya manusia di Dinas Lingkungan Hidup yang jumlahnya belum memadai untuk melakukan pengawasan.

Published: December 2020

No momento em que o mundo vive o drama da pandemia do COVID-19, vai se revelando a relevância do Sistema de Saúde Público, que tem se mostrado como o meio mais eficiente para o combate ao vírus e atendimento as vítimas. No Brasil muitos dos críticos ao modelo do Sistema Único de Saúde (SUS), tornam-se defensores do mesmo. Nesse contexto, nossa reflexão visa analisar as bases que referenciam a distribuição dos serviços de saúde pelo território e como essa distribuição vem se conformando no espaço regional comandado por Sobral, cidade localizada no noroeste cearense do Nordeste do Brasil e que juntamente com mais quatros polos formam as cinco macrorregiões de saúde do Ceará. As análises realizadas a partir de Sobral nos permitem inferir que a territorialização do SUS, mesmo com algumas ausências tem sido fundamental no combate a difusão do novo Coronavírus e socorro aos pacientes, a relevância ocorrendo desde os Centros de Saúde da Família (CSF) aos Centros de Saúde de maior complexidade, a exemplo de Sobral, que conta também com uma gestão pública municipal mas austera no enfrentamento a pandemia.
