AbstractFriction of textiles on the human forearm is an important factor in comfort sensations of garments. We built an experiment to measure friction for textiles sliding on the forearm under loading conditions which are characteristic for wearing shirts or jackets. The hair coverage of the participants’ forearm was quantified by image analysis of photographs of the arm in the region of contact. Friction results for five standard textiles suggest to treat hair coverage in two classes. Sweating after physical activity leads to an increase of friction by factors of 2 to 5 for participants with less hairy forearms, while an increase by a factor of 1 to 1.7 only was found for participants with more hairy forearms. We introduce a method of wetting the forearm of study participants in a controlled way with water, which results in similar friction as for the sweating forearm after physical activity. The method allows for efficient studies of the role of skin moisture for friction including varying hair coverage of the skin.

This article investigates the role of relational motives in the saying-is-believing effect ( Higgins & Rholes, 1978 ). Building on shared reality theory, we expected this effect to be most likely when communicators were motivated to “get along” with the audience. In the current study, participants were asked to describe an ambiguous target to an audience who either liked or disliked the target. The audience had been previously evaluated as a desirable vs. undesirable communication partner. Only participants who communicated with a desirable audience tuned their messages to suit their audience’s attitude toward the target. In line with predictions, they also displayed an audience-congruent memory bias in later recall.

Use of a method of share tendencies in the analysis time of some R-R intervals of the electrocardiogram after performance of 20 knee-bends and after 1 minute of restoration has allowed to establish a role of the centers of vegetative nervous system in restoration of a rhythm of heart at 4-th level of dynamic hierarchy. After 20-ти knee-bends and through 1 minutes of restoration the maximum vegetative centers of the central contour dominate. In interaction of the central and independent contours each center entering into them is characterized with distinctive features of dynamics which are shown in an increasing role of the centers of an independent contour after 1 minute of restoration.

In Slovenia, the role of general practitioners in counselling physical activity for prevention of cardiovascular disease (CVD) is well recognized. The role of general practitioners in advising healthy lifestyle for individuals who are at risk of developing CVD is formally defined in the National Program for Primary Prevention of Cardiovascular Disease, which has been running since 2001. Part of the program is counselling on healthy lifestyle including physical activity, performed in all health centres across the country. First a screening and medical examination is performed. In case of higher risk for CVD (>20%) the physician should give advice on the particular risk factor and direct patients to health-education centres, where they can participate in healthy lifestyle workshops lead by health professionals. Physicians and other health professionals who are involved in the implementation of prevention activities within the program need knowledge and skills that are crucial for successful counselling on healthy lifestyle. The educational program “basic education in health promotion and prevention of chronic non-communicable diseases in primary health care/family medicine” consists of two parts. The first part of the training is open to all health professionals working within the program. The second part is intended for health professionals working in health-education workshops. In the last few years a new family practice model has been introduced and disseminated. Some duties of the family physician, including health promotion and counselling, are being transferred to graduate nurses who become part of the family practice team. This new division of work undoubtedly brings many advantages, both in terms of the work organization, and of high-quality patient care. Nevertheless preventive action cannot be fully passed on to graduate nurses. Careful planning and education are needed to ensure a comprehensive approach in healthy life style counselling.

The outbreak of the COVID-19 pandemic caused a number of changes in social life around the world. In response to the growing number of infections, some countries have introduced restrictions that may have resulted in the change of the lifestyle. The aim of our study was to investigate the impact of the lockdown on body weight, physical activity and some eating habits of the society. The survey involving 183 people was conducted using a proprietary questionnaire. The mean age of the study participants was 33 ± 11 and mean height 169 ± 8 cm. An average increase in body weight was observed in 49.18% by 0.63 ± 3.7 kg which was the result of a decrease in physical activity and an increase in food consumption. We also observed a decrease in PAL from 1.64 ± 0.15 to 1.58 ± 0.13 and changes in the amount of food and individual groups of products consumption, including alcohol. Among the study participants who did not lose body mass, there was an average weight gain of 2.25 ± 2.5 kg. In conclusion, an increase of weight was shown in about half of the respondents in the study group which was associated with a decrease in physical activity and an increase in the consumption of total food and high energy density products.
