Abstract

The paper presents quasi 3D magnetic field computation for anisotropic layer structure of transformer core, but this computation method can be also applied to other magnetically non‐homogeneous structures. To compute magnetic flux density vectors in the layers of the structure the authors applied a new method based on the assumption that different distribution of the magnetic flux in particular layers results from the tendency to reach the minimum of the magnetic field energy.

Abstract

Purpose

The purpose of this paper is to assess nutritional habits and body composition parameters in the group of Polish pupils and students.

Design/methodology/approach

The study was conducted by the body composition analysis using the biological impedance method applying TANITA analyzer and diagnostic survey method using standardized direct interview with selected elements of the Sarzynska test. The research was carried out in various regions of Poland on a group of 1,000 pupils and students, using a targeted sample selection in the following subgroups: 250 middle school pupils, 250 high school students, 250 students living in a family home and 250 students living in an academic home.

Findings

Significantly the worst nutritional habits according to the Sarzynska test are shown by students living in academic home. As many as 21.6 percent of them eat very badly, while only 10.4 percent of students living in a family home eat very badly. This may indicate a lack of conditions, skills and time to prepare healthy meals, but also the lack of parental control in relation to what their child eats. The middle school pupils eat the healthiest meals (64.4 percent). It can be seen the regularity that the older the child is, the smaller the percentage of people in the healthy group.

Research limitations/implications

A research limitation was the little sample size of the study (1,000 person) and participants might have felt uncomfortable during research.

Practical implications

People planning class schedules should also plan breaks for a full-value meal. It is necessary to organize affordable courses that would teach simple and fast food preparation that does not require a lot of equipment and little popular ingredients. It would also be necessary to draw parents’ attention to excessive care and the fact that not allowing children to “experiment” in the kitchen may arouse in them the reluctance and fear of cooking.

Social implications

Among students, one should conduct universal education regarding a healthy lifestyle, which should focus on the subject of proper nutrition and physical activity, because there are no systemic solutions that would include adults. In order to improve nutritional habits, social rooms in academic homes should be adjusted so that students have the conditions to prepare nutritious meals, as well as provide access to canteens, where students would receive a reasonable meal at a reasonable price. The qualifications of the staff working there should also be improved.

Originality/value

The present study adds to the existing body of literature nutritional habits and body composition parameters in the group of Polish pupils and students. The results are the foundation for providing recommendations to policy makers, universitets, schools, food organizations and parents.
