A new technical system, CAREN (computer assisted rehabilitation environment), is described, which makes it possible to do a total body movement analysis in a virtual environment. The virtual environment is reproducible and as close to natural environment as possible. In a case study it proved possible with this system to test different shoes and get insight in the movement problems. The importance of whole body analysis is demonstrated in this case study. The adjustments made in the shoes could be tested for their efficacy.

And Behavior

The use of virtual reality (VR) promises enormous potential for studying human behavior. While approach and avoidance tendencies have been explored in various areas of basic and applied psychology, such as attitude and emotion research, basic learning psychology, and behavior therapy, they have rarely been studied in VR. One major focus of this research is to understand the psychological mechanisms underlying automatic behavioral tendencies towards and away from positively or negatively evaluated stimuli. We implemented a whole-body movement stimulus-response compatibility task to explore approach-avoidance behavior in an immersive virtual environment. We chose attitudinal stimuli—spiders and butterflies—on which people widely agree in their general evaluations (in that people evaluate spiders negatively and butterflies positively), while there is still substantial inter-individual variance (i. e., the intensity in which people dislike spiders or like butterflies). We implemented two parallel approach-avoidance tasks, one in VR, one desktop-based. Both tasks revealed the expected compatibility effects that were positively intercorrelated. Interestingly, however, the compatibility effect in the VR measure was unrelated to participants’ self-reported fear of spiders and stimulus evaluations. These results raise important implications about the usage of VR to study automatic behavioral tendencies.

ABSTRACT Using a whole-body counting technique with 131I-labelled thyroxine, measurements were made in euthyroid volunteers of fractional thyroxine degradation rate, total thyroxine turnover and thyroidal secretion of thyroxine. Thyroidal accumulation of 127I was also calculated from the chemical assay of 24-hour urine. The measurements were made in 18 subjects during the administration of 0, 100 and 200 μg of thyroxine per day in successive seven-week periods, and in 10 subjects during the administration of 0, 252 and 1009 μg of iodide daily in successive thirteen-week periods. When thyroxine was administered, the fall in thyroidal secretion rate was found to be parallel to the fall in radioiodine clearance rate. However, during administration of iodide thyroidal radioiodine clearance fell without appreciable alteration in total turnover of thyroxine. In addition thyroid iodine turnover increased progressively with increasing iodine intake and reached a mean value of 221 μg daily on a mean intake of 1250 μg I daily. The data indicate that the total body turnover of thyroxine is the quantity which is maintained in thyroid homeostasis. These data also indicate that the most significant effects on thyroid function of a chronic moderate increase in iodine intake are a) an inhibition of iodide concentrating activity, and b) an augmentation of nonthyronine iodide secretion. Neither effect is mediated by TSH.

1. The potassium status of uraemic patients was assessed by measurements of leucocyte potassium, erythrocyte potassium, exchangeable potassium (42K) and total body water (3H). The difficulties involved in assessment of exchangeable potassium and whole body potassium are discussed, and the advantages of the leucocyte as a model for the study of intracellular potassium are described. 2. in twenty-three measurements in sixteen undialysed uraemic patients, two patterns of reduction in intracellular potassium concentrations could be discerned in the leucocyte: (a) due to reduction in potassium related to cell solids; (b) due to an increase in cell water. Both abnormalities were present in some patients. 3. Similar measurements were made in eighteen uraemic patients receiving regular haemodialysis against dialysis fluid with a potassium concentration of 1 mmol/l. in this group leucocyte potassium did not differ significantly from normal, while leucocyte water content was slightly less than normal. 4. It is concluded that disturbances of leucocyte water and potassium are common in advanced uraemia, and that these functions tend towards normal during regular dialysis using dialysis fluid with a low potassium content.

Rope Skipping

As a whole-body sport, skipping rope plays an increasingly important role in daily life. In rope-skipping education, due to the lack of professional teachers, the training efficiency of students is low. The rope-skipping monitoring device is heavy and expensive, and the cost of labor statistics and energy consumption are high. In order to quickly analyze the movement process of students and provide correct guidance, this article implements the movement analysis method of the human body movement process. The problem of limb posture analysis in rope skipping is transformed into a multilabel classification problem, a real-time human motion analysis method based on mobile vision is proposed, and the algorithm model is verified in the rope-skipping scene. The experimental results prove that this paper proposes the improved algorithm, which achieved the expected effect. In the analysis of rope-skipping action, the choice of hyperparameters during the experiment is introduced, and it is verified that the proposed ALSTM-LSTM can solve the problem of multilabel classification in the rope-skipping process. The accuracy rate reaches 95.1%, and it can provide the best in all indicators and good performance. It is of great significance for movement analysis and movement quality evaluation during exercise.

AbstractThis study details the non-destructive chemical analysis of composite silver objects (ewers, situlas, amphora and casket) from one of the most significant late Roman finds, the Seuso Treasure. The Seuso Treasure consists of fourteen large silver vessels that were made in the fourth–early fifth centuries AD and used for dining during festive banquets and for washing and beautification. The measurements were systematically performed along a pre-designed grid at several points using handheld X-ray fluorescence analysis. The results demonstrate that all the objects were made from high-quality silver (above 90 wt% Ag), with the exception of the base of the Geometric Ewer B. Copper was added intentionally to improve the mechanical properties of soft silver. The gold and lead content of the objects shows constant values (less than 1 wt% Au and Pb). The chemical composition as well as the Bi/Pb ratio suggests that the parts of the composite objects were manufactured from different silver ingots. The ewers were constructed in two ways: (i) the base and the body were made separately, or (ii) the ewer was raised from a single silver sheet. The composite objects were assembled using three methods: (i) mechanical attachment; (ii) low-temperature, lead-tin soft solders; or (iii) high-temperature, copper-silver hard solders. Additionally, two types of gilding were revealed by the XRF analysis, one with remnants of mercury, i.e. fire-gilding, and another type without remnants of mercury, presumably diffusion bonding.

Dynamic Olfactometry

Odour concentration measurements in a chosen industrial source were made in this study using the method of dynamic olfactometry. The two different scenarios considered the variation of the odour emission rate as input for the dispersion model were compared for the period 2017 (before installation of the equipment for gas treatment) and 2018 (after implementation of purifying technologies). In this paper the odour impact range was determined by applying model calculations conducted in the Polish reference dispersion model – OPERAT FB software for the grid size 2 x 2 km. The conducted research shows a significant improvement in the odour impact range of chosen industrial source in year 2018 compared to 2017.
