Consumer properties of the thermal and electric energy which are the products at energy markets yield interconnections that have significant impact on the laws of energy consumption. When physical or price restrictions of the thermal energy supply are present at the power markets, the shortage of energy can be compensated by an increase in electricity consumption. At the same time, it appears that the interconnection of heat and electricity consumption largely determines the model of ower supply organization. Our paper analysed social and economic properties of the energy market. We show that in the case of separate production of heat and electric energy, these products yield the properties of substitutes for the consumers at the energy market. Our results show that heat and electric energy are interchangeable and the increase in the cost of one of them leads to its replacement by the other. At the same time, we find that for the countries with the welldeveloped combined production of heat and electric energy from the same energy source (the so-called cogeneration) which is typical for countries with a cold climate, the interrelationship between heat and electricity acquires a complementary nature, and the rise in prices for one commodity will not necessarily lead to a significant increase in demand for the other.

This work makes it possible to link ground rules for thermal and electrical energy markets with generation plant operating. Here we consider various procedures for optimization of combined heat and power plant operating mode by means of underutilized equipment mothball. This work results in process flow diagrams for turbine hall and relative increment charts, which can be used for plant loading in the optimal way.

The review of cost allocation methods when forming cost of energy with the combined production was carried out. Their strengths and weaknesses were revealed. The article is devoted to the development of the distribution system costs in the form of energy cost.

Introduction. The issues of dispensary check-ups for women with benign breast diseases (BBD) still remain an urgent challenge. What stands out are delayed visits to the doctor, irregular examinations and failure to follow prescribed therapy. Women’s health schools equipped with state-of-the -art information and communication technologies contribute to improving motivation for regular check-ups, timely examinations and adherence to treatment.Aim. To study the impact of training on adherence to regular visits, examination and treatment provided to a dispensary group of women with BBD at the Prevention School.Materials and methods. A total of 486 women with BBD who attended the Women’s Health Prevention School were observed. A professional medical advice included a gynaecological screening and consultation with an oncologist, breast ultrasound imaging for women of all age groups and mammography for women aged 40 years and older; once diffuse benign changes to breast tissues were detected, the women were prescribed Mastodynon (Bionorica SE) for 3 months.Results. After training, the rates of visits to a doctor increased from 69.3% to 94.2%, the examination rates increased from 66.8% to 88.6%, adherence to regular therapy increased from 43.6% to 82.9%. 82.9% of women reported health improvements after therapy with the herbal medicine, 7.6% – absence of changes, 4.3% – deterioration in the condition, of which 2.6% – menstrual disorders, 5.2% women discontinued therapy (due to poor tolerance – 3.6%, skin reactions – 1.0%, family reasons – 0.6%).Conclusion. Raising women’s awareness about breast cancer and a set of measures increase the early detection of breast diseases and women’s cancer alertness.
