MINIMIZATION OF THE CHEMICAL POLLUTION LEVEL AT THE WORKING ZONES IN OPEN AREAS USING SCREENS
Authors: Biliaiev M. M. , Rusakova T. I. , Shynkarenko V. I. 
Published: July 2019

Purpose. The scientific work aims to develop a new method for assessing the level of chemical air pollution in working zones located in open areas near highways using screens of different heights. Methodology. The analytical method for calculating the airflow velocity field near protective screens is based on the mathematical apparatus of the theory of complex variable functions, which allows obtaining the value of the velocity potential and the flow function, to calculate the velocity value at any point of the plane with a screen of different height. The obtained velocity field is used to calculate the level of carbon monoxide concentration in the numerical solution of the two-dimensional mass transfer equation. Findings. The developed program of numerical calculation allows conducting computational experiments on the effectiveness of the use of protective screens, taking into account changes in their geometry and meteorological conditions. The developed method based on the obtained concentration field makes it possible to carry out an assessment of the risk of chronic intoxication for the employees of the take-out trade, who are within the zone of the emission source (highway) for a long time. Originality. The regularities of changes in the concentration of carbon monoxide are established depending on the distance to the emission source at a height of 2 m from the ground in the presence of a screen of a certain height and in its absence. A risk assessment of chronic carbon monoxide intoxication has been carried out for take-out trade workers near the highway. It is shown that the presence of the screen reduces the risk of chronic CO intoxication by 10% as compared to its absence. Increasing the screen height to 1.8 m reduces the risk of chronic intoxication by 6% relatively to the situation when the screen height is 1.2 m. Practical value. The developed numerical-analytical method for calculating the level of chemical pollution in working zones in open areas and the program «Screen» created on its basis allow us to carry out a prompt forecast of atmospheric air pollution level with carbon monoxide taking into account the effectiveness of the screens. Quantitative results are necessary at the planning stage of trading places near highways, during the architectural-planned reorganization of adjacent developments.

Abstract: Mathematics is a science that is universal and able to integrate with other subjects. One of the goals of mathematics learning based on Kurikulum Tingkat Satuan Pendidikan is to understand, explain and apply mathematical concepts in the context of problem solving. But in the field, the students tend to difficulties in resolving problems related to problem solving in mathematics. This is due to the low ability students in mathematical problem solving in students' learning because not used to thinking creatively. It required a real effort to improve students' problem-solving abilities in mathematics. One of the measures taken namely through mathematics model Multy Discourse Representation (DMR). Learning with models DMR is one alternative that can be used because it exposes students to work in groups, in order to issue a power of representation held by the students.Keyword: Problem solving ability, DMR Model, Mathematic learning. Abstrak: Matematika merupakan suatu ilmu yang sifatnya universal dan mampu berintegrasi dengan mata pelajaran lain. Salah satu tujuan pembelajaran matematika berdasarkan kurikulum tingkat satuan pendidikan adalah memahami, menjelaskan dan mengaplikasikan konsep matematika dalam konteks pemecahan masalah. Namun dalam pelaksanaan di lapangan, siswa cenderung kesulitan dalam menyelesaikan persoalan terkait pemecahan masalah dalam pembelajaran matematika. Hal ini disebabkan rendahnya kemampuan siswa dalam pemecahan masalah matematis karena dalam pembelajaran siswa tidak terbiasa berpikir secara kreatif. Untuk itu diperlukan upaya nyata dalam meningkatkan kemampuan pemecahan masalah siswa dalam pembelajaran matematika. Salah satu upaya yang diambil yakni melalui pembelajaran matematika dengan model Diskursus Multy Representation (DMR). Pembelajaran dengan model DMR merupakan salah satu alternatif yang dapat digunakan karena menghadapkan siswa kepada bekerja secara berkelompok, supaya dapat mengeluarkan daya representasi yang dimiliki oleh diri siswa.Kata kunci: Kemampuan pemecahan masalah, Model DMR, Pembelajaran matematika
