The diagnosis of morphological characteristics is an integral part of the entire training process in sports. This study aimed to determine the influence of morphological characteristics on the ball's speed of movement after the shoot from a spot and movement in handball. The sample included 36 female handball players aged 14.33 years. The predictor set consisted of 10 morphological variables. In comparison, the three variables constituted the criterion variables by which the ball's speed of movement was determined after different ways of shooting. Using regression analysis, it was found that the predictor set of variables explains about 70% of the variance for all three criterion variables. Individually, a statistically significant and positive influence on the speed of movement of the ball after the shot was recorded at the height and weight of the body, while a negative effect was observed for the variables; arm length, leg length and skin fold on the abdomen. Based on the results obtained, it can be concluded that morphological characteristics significantly influence the speed of movement of the ball after a shot in the handball, which can significantly contribute to the selection of handball players, as well as in establishing the tactics of handball, especially in situations where one shot decides the match. Also, the obtained results indicate the necessity of considering the age characteristics of the female respondents, that is, the need to adjust the training process to the period of intensive growth and development.

At the sample of 39 water polo players, aged 12 years (± 6 months), the research was conducted todetermine the impact of morphological characteristics on the situational performance in the waterpolo. In this paper, a set of 12 anthropometric measures as a predictor set of variables was applied,while the criterion variables were situational motor tests; swimming speed at 25 meters with andwithout a ball, vertical jump from the water and side swimming 8 times 2.5 meters. On the basis of theobtained results it was concluded that the morphological characteristics significantly influenced theperformance of situational motoric tasks in water polo, depending on the test from 39% to as much as71%. The most significant applied variables from the morphological space of water polo players werevariables; the volume of the thorax, the height of the body, the width of the hand and the foot with apositive effect, while the weight of the body and the subcutaneous fatty tissue were aggravating factorsfor the performance of situational motoric tasks for the 12-year-old water polo players.

Introduction. Modern sports places high demands on the functional systems of the body at all stages of the training and competitive processes. High loads create signifi cant background for the occurrence of musculoskeletal diseases, among which the myofascial syndrome (MFS) holds the leading position. MFS negatively affects the functional readiness of the sportsman′s body and is a risk factor for injuries of the musculoskeletal system. In this regard, timely treatment of MFS is important. It creates the conditions for the improvement of sports achievements, for health maintenance and sports longevity. Treatment of patients with MFS should include methods that normalize trophism and muscle tone. Given the problem of doping, the use of non-drug methods, including osteopathy, is preferable. The goal of research — to develop a system of monitoring and osteopathic correction of myofascial disorders (MFD) and to introduce it into the practice of medical and biological support for sportsmen of different categories and levels during the annual training process.Materials and methods. 93 sportsmen (45 women and 48 men), mean age 22,1±1,1 years, representing diffe rent sports were examined. The essence of the proposed system is regular clinical and electroneurophysiological monitoring of the body condition and preventive correction of myofascial disorders in order to exclude their infl uence on the success of sports activities.Results. It was established that the proposed system of monitoring and osteopathic correction led to a signifi cant reduction in clinical and electroneurophysiological manifestations both in local and in extensive forms of myofascial disorders, which allowed to maintain the optimal functional readiness of sportsmen throughout the entire annual training cycle.Conclusion. The system of monitoring and correction of MFS with the use of osteopathic treatment can be one of the elements of medical and biological support for sportsmen during the annual training process.

The COVID-19 pandemic has put a hold on the Silent Mentor Programme (SMP); this pause has not only caused unprecedented challenges for the delivery of medical education but has forced changes in the programme ceremony sessions. We aimed to describe the psychological impact and experiences of family members of silent mentors during the COVID-19 pandemic using qualitative interviews. Many expressed feelings of remorse and unrest about the unprecedented delay of the SMP. The delay increased negative emotions particularly among some elderly family members; however, there was no prominent negative effect on their functional health and well-being. Several participants relayed the belief that the soul cannot rest until the body receives a proper burial while some worried about the deterioration of the physical condition of the mentors. In conclusion, findings provide insights into the importance of not overlooking the mental health implications of delaying the SMP in future outbreaks or crises.

Purpose This study aims to empirically examine whether the political connection is related to risk disclosure practices. The study also seeks to contribute to the existent risk disclosure literature by investigating the moderator effect of family ownership on this relationship. Design/methodology/approach The content analysis approach was used to collect data and determine the level of risk disclosure over the non-financial Jordanian firms listed on 1Amman Stock Exchange. The sample of this study contains 376 annual reports over four years from 2014 to 2017. It used the random effect regressions to examine the hypothesis of the study. Findings The results show that politically connected companies disclose less risk information than the unconnected ones in Jordan. The results also refer that family ownership contributes in mitigating the negative effect of the political connection on the level of corporate risk. Practical implications The results have implications for regulatory institutions such as the Jordan Securities Commission to take the negative effect of political connection in their consideration and impose further regulations to monitor this board’s attribute and control politicians’ domination on the board decisions. Originality/value The current study also contributes to the body of literature by investigating the effects of the political connections on the level of risk disclosure in the financial reports. To the best of the authors’ knowledge, the current study is the first to examine the effect of the political connection on the risk disclosure practices. Moreover, the study is among the first studies that examine the moderating role of family ownership on such relationship.

Walkowiak, Ute R.Hülsheger & Fred R.H. Zijlstra, Gedrag & Organisatie, volume 23, December 2010, nr. 4, pp. 316-332. Previous research showed that the experience of high work pressure can lead to fatigue and even to health complaints on the long term. This makes it very important, especially for people who experience high work pressure, to take sufficient time to recover after work. Sleep quality has a positive influence on recovery. The aim of this diary study was to investigate whether sleep quality has a mediating effect on the relationship between work pressure and recovery. Seventy-six people took part in the study and answered questions about work, recovery and sleep for 14 days. Results showed that work pressure indeed had a negative effect on recovery and sleep quality. Furthermore, we found a partial mediation effect: sleep quality mediated the relationship between work pressure and recovery. These results stress the importance of recovery and sleep quality, especially for people who experience high work pressure.

High Incidence Rate

Organization of care for patients with glomerulonephritis is a rather urgent problem today, due to the high incidence rate and the tendency to progression of renal dysfunction. When discussing treatment issues, it is necessary to pay attention to the fulfillment of three basic requirements for patients, which include normalization of the life regime (in particular, the exclusion of night work, avoiding stressful situations and heavy physical activity when having high blood pressure), the implementation of certain dietary recommendations and prolonged drug treatment [3]. Diseases of the kidneys as the main organ, the affection of which leads to a deterioration of excretory function, require a special diet with a restriction of a number of products. Against the background of glomerulonephritis disruption of the process of glomerular filtration, which in some cases leads to the development of renal failure, it is necessary to reduce the intake of food substances that can have a negative effect on the body — alcohol, smoked meats, spicy, salty foods, preserves, sausages, foods with high protein and salt content. Moreover, one should also take control of the amount of fluid consumed and ensure compliance with the frequency and regularity of food intake.

The relevance of research is associated with the cultivation of healthy and highly productive animals and poultry in order to ensure the food security of the Republic of Kazakhstan.The studies carried out to assess the toxicological parameters of montmorillonite clay in order to use them as an aluminosilicate sorbent in experimental animals (rabbits and white rats) allowed the following results to be obtained: Visual study of the intensity of erythema when exposed to the test substance on the skin of rabbits showed their absence (0 points). The study of the intensity of edema (an increase in the thickness of the skin clutch of rabbits) when exposed to the test substance on the skin of rabbits showed no reaction (0 points). Studies evaluating the irritating effect of the test substances on the mucous membranes of the eyes of rabbits by symptoms of damage showed the absence of hyperemia (0 points). Weak eyelid edema (1 point), the minimum amount of discharge in the corner of the eye (1 point). The results of studies on the classification assessment of the test substance for the severity of the irritant effect on the eyes of rabbits showed that the average total score of the severity of the irritative effect corresponds to 1 point. A comprehensive analysis of the results obtained on the basis of scientific and experimental studies to assess the toxicological indicators of montmorillonite clay from the Pogadaevskoye deposit in relation to irritating effects on the skin and mucous membranes of experimental animals (rabbits) showed their harmlessness.

Black-winged myna (Acridotheres melanopterus) is an endemic bird of Java and Bali, currently critically endangered based on International Union of Conservation for Nature (IUCN) since 2010. The study about black-winged myna morphological characteristic is important because it has two relatives with almost identical features of morphology. The information can be used as a basis in breeding management to avoid hybridization. The study aims to determine the morphological characteristics of black-winged myna. The sample selection was done using purposive sampling method. Data was taken from 36 black-winged mynas with >=2 years old. Data collection was done by measuring and documenting every morphological feature of the observed body parts. Documentation of the wings, back, chest, head and sides of the body are taken from each bird using a digital camera. The results showed that almost the entire body of black-winged myna covered by white feather, black feather only present on the cover of the wings and tail. Black eyes surrounded by yellow skin without feather. The beak is orange with blackish parts around the nostrils. The bird has yellow legs with three fingers at the front and one finger at the back. The average body length of this bird is 22.5 cm, weight 89.02 g, width 5.98 cm, body circumference 14.36 cm and wingspan 38.49 cm.

The study aimed at describing objectively the interdependence between body weight (BWT) and morphometric traits in Khaki Campbell and Pekin ducks using multivariate path analysis technique. Measurements were taken on one hundred and ninety seven (197) randomly selected 10-week old Khaki Campbell and Pekin ducks, respectively in Plateau State, Nigeria. The birds were reared on deep litter in a semi-intensive system where they were kept in a fenced area provided with water ponds and locked up in the poultry house during the night. The body parts measured were, body length (BDL); thigh length (THL); thigh circumference (THC); breast circumference (BTC); bill length (BLL); neck length (NKL); neck circumference (NKC); shank length (SHL); shank width (SHW); total leg length (TLL) and wing length (WL). General linear model was used to study genotype and sex effects. Pekin ducks had a superior advantage (p<0.05) over their Khaki Campbell counterparts in all the body parameters estimated. Sexual dimorphism (p<0.05) was in favour of male ducks.  Pairwise phenotypic correlations between BWT and morphometric traits were positive and significant (p<0.01), ranging from 0.38-0.95 and 0.35-0.92 for Khaki Campbell and Pekin ducks, respectively. Path analysis revealed that BDL was the variable of utmost importance directly influencing BWT in male Khaki Campbell and Pekin ducks (path coefficient=0.535 and 0.508, respectively; p<0.01) while BTC and SHL were the most responsible parameters affecting BWT in female Khaki Campbell and Pekin ducks [path coefficient=0.594 (P<0.01) and 1.197 (p<0.05), respectively]. The optimum regression models for the prediction of BWT in Khaki Campbell ducks included BDL, SHL, BTC and NKC (male)  and BDL, WNL and BTC (female); while in their Pekin counterparts, BDL, BLL and BTC (male) and BDL and SHL (female) were incorporated.DOI: http://dx.doi.org/10.3329/bjas.v44i1.23112            Bang.
