The paper discusses conditions of proper communication between the doctor and the patient focusing on the Treatise of the Hypochondriack and Hysterick Passions (1711) by Bernard Mandeville. The method of treating hypochondria, based mainly on dialogue, presented in this work allows the doctor to correctly recognize disease and to awaken self-knowledge in the patient. Combining hypochondria with stomach problems, expanding the field of factors influencing the development of this disease proves that Mandeville interprets man holistically in the treatment process, and his preferred method focuses more on psychological rather than physical problems. Philopirio, as a representative of Mandeville’s medical views, assumes the role of a medical advisor, whose main task is physical and constant contact with the patient. The Philopirio’s method of treatment becomes effective thanks to medical virtues, especially diligence and empathy. Mandeville’s work unambiguously proves that in the process of diagnosis and convalescence communication between the doctor and the patient has an important role, and sometimes it is essential in the process of curing the patient.

The paper presents a method of priority scheduling that is useful during the planning of multiple-structure construction projects. This approach is an extension of the concept of interactive scheduling. In priority scheduling, it is the planner that can determine how important each of the technological and organisational constraints are to them. A planner's preferences can be defined through developing a ranking list that defines which constraints are the most important, and those whose completion can come second. The planner will be able to model the constraints that appear at a construction site more flexibly. The article presents a general linear programming model of the planning of multiple-structure construction projects, as well as various values of each of the parameters that allow us to obtain different planning effects. The proposed model has been implemented in a computer program and its effectiveness has been presented on a calculation example.

The paper presents results of a study concerning ammonium and nitratc(V) fixation by soil irrigated with municipal wastcwatcrs ( 1 - 60 mm and 2 doses - 120 mm) and estimation or the possibility or using organic soil and grass-mixture for the wastewater treatment. It was found that the studied soil and the plant applied showed a very high capacity or binding ammonium ions (up to 96%), and lower in the case ofnitrates(V) (up to 71 %). It was also demonstrated that the single irrigation dose was better utilized compared to the double dose.
