Introduction. The work of many employees in the service sector is associated with a constant stay in a forced working position sitting at the computer for up to 60-80% of the time of the entire work shift, which leads to fatigue. The rate of fatigue depends on the specifics of work: it is much more likely to occur when working with monotony, muscle tension. An important role in the appearance of fatigue is also played by the attitude of a person to the work performed. The aim of study is to study the motor activity of knowledge workers in social service centers for the development of preventive measures aimed at reducing hypokinesia and hypodynamia during the work shift. Materials and methods. The following methods were used in the study: questionnaire and working day timing, calculation methods to determine whether the actual body weight corresponds to the ideal one using the Broka’s index and the Ketle’s index. The study involved employees of the integrated social service center "Raduga" in Bugulma. Results. An assessment of the motor activity of employees of the social service center of the population was made, and it was concluded that the problem of hypokinesia and hypodynamia is relevant and significant for employees of social service centers of the population both in their daily activities and during the work shift. Most of the employees showed an increase in actual body weight compared to the ideal one, which is to some extent due to hypokinesia and hypodynamia both during the working day and at home. Conclusions. Preventive measures aimed at compliance with the principles of rational nutrition and a healthy lifestyle, work and rest regimes, high-quality preliminary and periodic medical examinations are proposed.

To the Editor.— This letter is in response to the article entitled "Weight and Menstrual Function in Patients with Eating Disorders and Cystic Fibrosis."1 Under "Methods," the authors describe a method for calculating percent ideal body weight by plotting the patient's height on standard growth curves derived from the data of Hamill et al,2 and the ideal body weight being the weight at the same percentile for age. Using the tables of Hamill to calculate percentages of height and weight for females older than 10 years and males older than 11½ years should be done cautiously.

Simplified technical and economical analysis of a total of 12 different ship designs has been performed and compared with operational profiles of typical North Sea Diving and Construction vessels. Evaluation of what impact changes to the operational profile has on the best-suited vessel for the operation has also been performed. The paper focuses on optimizing the design to achieve a maximum of days in operation working day. Nomenclature

We examined the effects of injections of systemic [lipopolysaccharide (LPS), 2.5 mg/kg or 50 pg/kg ip] or local (turpentine, 100 microl sc) inflammatory stimuli on fever, motor activity, body weight, and food intake in tumor necrosis factor (TNF) double receptor (TNFR)-knockout mice. A high dose of LPS resulted in exacerbated fevers in TNFR-knockout mice compared with wild-type mice for the early phase of fever (3-15 h); the late phase of fever (16-24 h) and fevers to a low dose of LPS were similar in both groups. Motor activity, body weight, and food intake were similarly reduced in both groups of mice after LPS administration. In response to turpentine, TNFR-knockout and wild-type mice developed virtually identical responses to all variables monitored. These results suggest that 1) TNF modulates fevers to LPS dose dependently, 2) TNF does not modulate fevers to a subcutaneous injection of turpentine, and 3) knockout mice may develop cytokine redundancy in the regulation of the acute phase response to intraperitoneally injected LPS or subcutaneously injected turpentine.

AbstractOne of the essential elements of work technology assessment is task performance time. In the working day structure, production times are crucial; however, under certain conditions, complementary work times can have a share of up to 30%. Accurate determination of the time structure of a work shift is very time consuming and requires time measurements using the methods of cumulative timing or snapshot observations. For this reason, the overall share of complementary work times in a work shift is usually estimated roughly, equally for all timber harvesting conditions. The aim of this study was to determine the impact of selected working environment factors on the share of complementary work times in a work shift, in technologies on the manual-machine and the machine levels. The analyses were carried out in 33 forest districts of the Regional Directorate of State Forests in Wrocław. Among forest contractors, surveys were carried out to analyse the time structure of a working day. For each forest district, analyses of environmental factors potentially relevant to the share of complementary work times in a work shift were carried out; these included field features, dispersion of stands, features of timber, area accessibility. The total share of complementary work times in the machine-level technology variant amounted to approx. 40% and was higher than the manual-machine technological variant, where this share amounted to approx. 35%. The models developed for standardization of the share of variability of complementary work times, in the case of the manual-machine technology level, took into account the share of timber assortments with the length of over 2.5 m as well as the share of upland and mountain sites. In the case of timber harvesting at the machine technology level, the standardization model included as significant the factors such as the share of coniferous forest sites, the number of forest complexes with an area of over 100 hectares, and the total length of roads. Therefore, the above features could be selected as decisive for the share of the complementary work time category out of the full set of environmental variables taken into consideration in the estimation of the time-consumption of timber harvesting processes.

In a double-blind trial, 12 out-patients with primary anorexia nervosa received, for six weeks, either 10 mg cisapride or placebo, three times a day. Cisapride accelerated gastric emptying of a radiolabelled semisolid meal in all six patients; five gained weight and symptoms of gastric retention ameliorated in four. With placebo, three of six had emptying enhanced, four gained weight, and one's symptoms improved. For another six weeks, all patients received cisapride. In five of the patients who had received cisapride, emptying further accelerated or remained stable; in one it slowed. Of the six patients who received placebo, four had emptying accelerated, five gained weight, and symptoms improved in four. Longer administration of cisapride may, by enhancing gastric motor activity, alleviate symptoms of retention and thus help to change eating behaviour.
