Published: June 2020

Researchers point at the need to study the creative processes of students in problem solving, as these may indicate how to encourage creative problem solving. The present research attempts to study, based on the heuristic framework of Polya, pre-service teachers' flexibility processes when they solve a mathematical problem with technology. The research was held in a teacher college, where two second-year classes of 49 mathematics pre-service teachers (24 in the academic year 2017-2018 and 25 in the academic year 2018-2019) participated in the research. The pre-service teachers were requested to solve the halving-the-rectangle problem with technology, specifically with the GeoGebra software. The research results indicated that generally the participants, who performed flexibility processes, used a sequence of creativity processes: conjecturing, specialization, verifying consequences with technology and generalization. The conjecturing process utilized mathematical relationship or inference from analogy, where the inference from analogy advanced gradually through solution modifications.

He most important trends in reforming national education systems in most developed countries are the internationalization of the education system and the integration of the educational space. Both Ukraine and Kharkov National Medical University joined this process. Therefore, at present, the task has arisen of creating unified educational programs for the training of masters in specialty 224 «Technologies for medical diagnostics and treatment» specializing in laboratory diagnostics.
Such a curriculum was the silabus created by the Department of Radiology and Radiation Medicine of KNMU, that is, information about the subject of study of a discipline, a description of interdisciplinary connections, goals and objectives of a discipline, competence (integral, general and special) and learning outcomes, a thematic plan, description independent work of students, the definition of knowledge control methods, a description of the assessment of the discipline, a list of educational literature or online sources for preparing students.
Unlike the traditional curriculum, the force bus includes exactly three types of competencies, which allow the student to gain experience in successful contact with other students, teachers, in the future — with colleagues and work experience in a «team». In addition to special knowledge and skills, a student at the end of higher education becomes an educated member of a social society, can fulfill not only his professional or professional duty, but also has a certain civic position. In addition, the modern system of higher education involves continuing education throughout the professional life
THE CONTENT OF VEGF, COX-2 AND PGE-2 DEPENDING ON THE OBJECTIVE RESPONSE TO RADIATION THERAPY IN COMBINATION WITH A COX-2 INHIBITOR IN PATIENTS WITH NON-SMALL CELL LUNG CANCER
Authors: Mitryaeva N. , Belozor N. , Starenkiy V. , Grebinyk L. 
Published: June 2020

Objective: to evaluate the levels of VEGF, COX-2, PGE-2 in comparison with the effectiveness of radiation therapy with or without a COX-2 inhibitor.
Materials and methods. The study involved 38 patients with non-small cell lung cancer (NSCLC) aged 32 to 80 years (median — 66 years), stage III of the process (50 %) prevailed, histological studies revealed squamous cell cancer in 74 %. To evaluate the results of the study, patients were divided into 2 subgroups: 1 — a subgroup (20 patients who received radiation therapy (RT) in combination with a COX-2 inhibitor — ranselex), 2 — a subgroup (18 patients who received RT). Radiation therapy was performed on linear accelerators Clinac 600C. During RT, patients received a COX-2 inhibitor — ranselex 100 mg per day. To determine the content of angiogenesis factors VEGF, COX-2, and PGE-2, blood sampling was performed in patients before irradiation and after a course of radiotherapy. The content of VEGF, COX-2, and PGE-2 was determined in blood serum by ELISA using standard reagent kits: of Vector-Best CJSC (Russia) for VEGF, commercial reagent kits of Invitrogen COX-2 ELISA Kit (Great Britain) and Prostaglandin T2 ELISA Kit (Germany).
Results. An elevated level of VEGF, COX-2, PGE-2 in the blood serum of patients with NSCLC before radiation treatment was revealed, which indicates the activity of neoangiogenesis processes in the tumor. It was found that in patients with NSCLC after RT in combination with the COX-2 inhibitor ranselex, a 1.9-fold decrease in VEGF was observed against a 2.4-fold decrease in the COX-2 content and 1.7-fold PGE-2. In RT without ranselex, VEGF decreased by 1.4 times and the levels of COX-2 and PGE-2 did not change, which indicates inhibition of the COX-2 inhibitor of angiogenesis. The relationship between the concentration of the pro-angiogenic factor VEGF and the levels of COX-2, PGE-2 and the objective response with which the direct effect of RT was evaluated was established. With regression of the tumor process, a decrease in the level of VEGF was observed, more pronounced in RT with ranselex, which indicates the effectiveness of RT. With progression, a consistently high level of VEGF was observed, which is an unfavorable sign and is possibly associated with the tumor resistance to the therapy and the further unfavorable course of the disease.
Conclusions. The relationship between the concentration of pro-angiogenic factors — VEGF, COX-2, PGE-2 and the objective response was determined, for which the direct effect of radiation therapy with or without a COX-2 inhibitor of ranselex (regression, stabilization, progression) was evaluated. It was shown that a more pronounced decrease in VEGF content is observed after radiation therapy (RT) with ranselex compared with RT without ranselex, which indicates inhibition of COX-2 inhibitor angiogenesis, and thereby leads to an increase in the effectiveness of RT.
Retrospective Analysis of Studies Examining Sensory Processing Preferences in People With a Psychiatric Condition
Authors: Brown Catana , Karim Rebecca , Steuter Megan 
Published: June 2020

Abstract
Importance: When occupational therapists understand sensory processing preferences, they can create environments that promote participation.
Objective: To determine the sensory processing preferences of people with a psychiatric condition as measured by the Adolescent/Adult Sensory Profile (A/ASP).
Data Sources: PubMed, PsycINFO, ERIC, CINAHL, and OTseeker were searched from 2002 through January 2018.
Study Selection and Data Collection: Studies that included people with psychiatric conditions and measured sensory processing preferences using the A/ASP were included. Studies had to report means and standard deviations for all four A/ASP subscales. The retrospective analysis involved extracting sensory processing quadrant scores from each study and comparing these scores with the A/ASP norms by means of independent-samples t tests.
Findings: Five studies revealed a general pattern of greater sensory sensitivity, sensation avoiding, and low registration and less sensation seeking among people with a psychiatric condition. For each condition (schizophrenia, high risk for psychosis, bipolar disorder, major depressive disorder, posttraumatic stress, and obsessive–compulsive disorder), scores in at least two of the four sensory processing quadrants were significantly different from the normative scores, with some variability in sensory processing preferences across the psychiatric conditions.
Conclusions and Relevance: The sensory processing preferences of people with a psychiatric condition differ from those of the normative sample. This research can lead to condition-specific sensory-based interventions targeting a person’s specific sensory needs in the context of occupational performance.
What This Article Adds: This article provides new information that compares and contrasts the sensory processing preferences of people with different types of psychiatric conditions. This information can be useful in treatment planning.
