Purpose: To analyze the changes in coordinates and distances among three typical geometric landmarks of the cornea, namely, the thinnest point (TP), maximum curvature (Kmax), and corneal apex (AP) during the development of keratoconus, and explore the potential relationship between these changes and the abnormalities of corneal biomechanics.Methods: Normal eyes (n = 127), clinical keratoconic eyes (CKC, n = 290), and the eyes of forme fruste keratoconus (FFKC, n = 85) were included; among them, the CKC group was classified into four grades based on the Topographic Keratoconus Classification (TKC) provided by Pentacam. A total of 38 Corvis ST output parameters and three distance parameters of three typical landmarks (DKmax-AP, DTP-AP, and DKmax-TP) based on Pentacam were included. The differences of parameters among the abovementioned six groups (Normal, FFKC, and CKC stage I to CKC stage IV) were analyzed. Spearman’s rank correlation test was performed to choose several dynamic corneal response (DCR) parameters that could best reflect the changes of corneal biomechanical characteristics during the progression of the disease, and the Pearson’s or Spearman’s correlation test was conducted to determine the association between the three distances and the selected DCR parameters in each grade. In addition, by flipping the X coordinate of the left eye on the vertical axis to reflect the direction of the right eye, the coordinates of TP and Kmax in different developmental grades were highlighted.Results: From CKC stage II, the three geometric landmark distances commenced to correlate with the corneal DCR parameters (CBI, SPA1, IR, DA Ratio 2, ARTh, MIR, Radius, Pachy, and DA Ratio 1), which could better represent the changes of biomechanical properties from normal cornea to keratoconus. From normal cornea to CKC stage IV, the coordinates of Kmax were gradually tended to the inferior temporal region from dispersion, while TP was always concentrated in the inferior temporal region. Although DKmax-AP, DKmax-TP, and DTP-AP all showed a gradual decreasing trend with the progress of the disease, the first two did not change significantly, and only DTP-AP significantly approached AP in the later stage of disease development. In addition, from the FFKC group, the corresponding values of DKmax-TP in each disease development group were smaller than DKmax-AP.Conclusions: In the later stage of keratoconus, the relationship between the three typical landmark distance parameters and DCR parameters is stronger, and even the weakening of corneal biomechanical properties may be accompanied by the merger of typical landmark positions.

Purpose: to determine the relationship between the performance of basic elements and indicators of static and dynamic balance in the training process of young acrobats 6-7 years. Material and methods. The study involved 16 young acrobats at the stage of initial training (age 6-7 years). All parents of the participants gave written consent for the participation of children in the study. The study involved testing the technique of performing basic elements of sports acrobatics and assessing the static and dynamic balance of young athletes. The relationship between (swallow, shoulder blade, forward squat, wheel (sideways overturning), bridges) and static and dynamic equilibrium tests was determined. Spearman's rank correlation coefficient method was used as a method of statistical analysis. Results. It is established that the largest relationship between the performance of basic elements and static balance in the basic exercises of young acrobats have: Romberg's test with the elements "Swallow", "Stand on the shoulders", "Bridge"; Biryuk test with elements "Swallow", "Wheel", "Bridge"; balance "Swallow" with elements "Swallow", "Wheel"; static equilibrium test with the elements "Swallow", "Rack on the shoulders", "Rolling forward with a squat", "Wheel". Reliable values ​​of the correlation coefficient were established between the tests of dynamic balance and the basic elements of sports acrobatics in young athletes 6-7 years, namely: "Swallow", "Flip forward with a squat", "Wheel" and "Bridge". The analysis of special tests of static and dynamic balance in mastering the basic elements of acrobatics at the first stage of long-term training makes it possible to use them to determine the level of coordination capabilities of young athletes and further improve the use of acrobatic exercises. Conclusions. A reliable relationship between the performance of basic exercises and indicators of static and dynamic balance in young acrobats at the initial stage of training. It is shown that the level of static and dynamic balance is of great importance for the assimilation and improvement of basic elements of technology by young acrobats 6-7 years. Static and dynamic balance tests can be used to individually build training programs and young acrobats. It is shown that sports acrobatics is a significant means of developing the balance of children 6-7 years.

Objective To compare dental arch dimensions of children in the primary dentition with repaired unilateral clefts of the lip and palate (UCLP) to a noncleft group of a similar age and determine how the dimensions of the cleft arches relate to an index of treatment outcome. Method Dental study casts of 44 5- to 6-year-olds with complete UCLP (22 boys and 22 girls) from a single center, whose primary surgery had been carried out by one surgeon, were matched for age, sex, and ethnicity with dental study casts from a longitudinal growth study. Analysis of variance was used to ascertain differences in arch dimensions between the two groups. The cleft group casts were then assessed with an established index of surgical outcome, the 5-year-old index. Spearman's rank correlation coefficient was used to see how the arch dimensions of the cleft group related to the categories of the index. Results and Conclusions Maxillary arch dimensions were significantly smaller in the cleft group than in the noncleft group, irrespective of sex (p < .05). In the mandibular arch, there was no difference between the cleft and noncleft groups (p > .05). Maxillary arch dimensions of the cleft group correlated significantly with the 5-year-old index for arch length and intercanine width (p < .05) but not intermolar width (p = .842). This would suggest that the 5-year-old index is a suitable tool for assessing the outcome of treatment in the primary dentition for anteroposterior and anterior transverse arch dimensions.

The Relationship

Dairy farming contributes about eight percent of National Gross Domestic Product with an annual milk production of 3.43 billion litres in Kenya. It supports the livelihood of approximately four million Kenyans through food provision, income generation and employment. However, milk production per individual animal in Kenya, averaging six to seven (6-7) litres/cow/day, is low compared to the world’s best at 10,133 litres/cow/year (28 litres/cow/day) mainly due to factors including poor feeding. This means that Kenya produces an average of 20 litres of milk less per cow per day compared to the world’s best. The objective of this study was to determine the effect of mineral mix and concentrate feeds on milk revenue of smallholder dairy farmers in Kapseret sub County. The study was conducted between the months of January-March, 2020. Primary data was collected using closed and open ended questionnaires. Spearman’s Rank correlation was used to show the strength of the relationship between the variables. Multiple regression model was employed to assess the effect of supplementation on milk revenue. Results were presented in tables, and descriptive statistics such as percentages and frequencies. The results indicated a positive and statistically significant relationship between the variables (concentrate feeds and mineral mix) and milk revenue at (r=0.41, p=0.001) and (r=0.30, p=0.001), respectively. The relationship between mineral mix and concentrate feeds was positive and statistically significant (r=0.92, p=0.001). Subsequent feeding of homemade or commercial concentrates and mineral mix to dairy animals influenced milk revenue. The study concluded that mineral mix and concentrate feeds increased milk revenue of smallholder dairy farmers in Kapseret sub County. The study recommended the use of mineral mix and commercial concentrates or quality homemade concentrates in order to increase milk produce which affects farmers’ milk revenue.

Abstract Background: This paper examines the relationship between selected motivation factors that affect the attitude to work among medical doctors at public hospitals and the organizational performance of hospitals .Methods: This study was based on World Health Organization questionnaires designed to estimate motivation factors according to Herzberg’s motivation theory and to measure the level of organizational performance of hospitals by using the McKinsey model . A survey was conducted among physicians (n=249) with either surgical (operative) or nonsurgical (conservative) specialty in 22 departments/units of general public hospitals in Warsaw, Poland. The relationship between the chosen job motivation factors and organizational effectiveness was determined using Spearman’s rank correlation. Furthermore, 95% confidence intervals were calculated. The independent samples t-test was used to confirm statistically significant differences between the independent groups. Normality of the data was tested by the Kolmogorov–Smirnov test.Results: The survey revealed that motivation factors related to “quality and style of supervision” have the highest effect on the organizational performance of hospitals (Spearman’s rank correlation coefficient = 0.490; p<0.001), whereas “performance feedback” has the lowest effect on organizational performance according to the surveyed healthcare professionals (54% of physicians). Conclusion: The principles of Individual Performance Review should be incorporated into strategies designed to improve the organizational performance of hospitals (with NHS serving as a potential role model) in order to establish specific rules on how to share performance feedback with individual physicians. The present study contributes to literature on human resource management in the healthcare sector and highlights the importance of nonfinancial aspects in improving the organizational performance of hospitals.

Moderate Stress

Background: Menopause is the cessation of the last menstruation that occurs in the climacteric period and the hormone estrogen is no longer formed. The older the age, the more diseases suffered at the age of menopause, such as hypertension. Hypertension is a condition when a person experiences an increase in blood pressure either slowly or suddenly. The factors that cause hypertension are mostly due to stress. This study aims to determine the relationship between stress levels with the incidence of hypertension in postmenopausal women. Methods: The design of this research is correlational analytic. The sample is 50 respondents with the Stratified Random Sampling technique. The instrument used is a questionnaire. The results of the study were analyzed using the Spearman rank statistical test. Result: The results showed that there were 24 people (48.0%) with moderate stress levels and 18 people (36.0%) experiencing Stage I Hypertension. The results of the Spearman's Rank correlation test showed that the value of value = 0.000 was smaller than the value of = 0.05 so that H0 is rejected and H1 is accepted, meaning that there is a relationship between stress levels and the incidence of hypertension in postmenopausal women. Conclusion: It is expected that respondents will increase their knowledge about how to deal with stress so that they do not experience stress at a severe level so that it does not have a bad impact on them.

The article presents research on the local property tax policy of rural and urban-rural municipalities in Poland. Various methods were used to investigate the data interdependencies of mathematical statistics (Pearson’s correlation test, Spearman’s correlation test and Pearson’s independence test). For direct data and coefficients, Pearson’s classic correlation was used. With regard to the processed, dichotomic and enumerated data (including the contingency tables), Spearman’s rank correlation was used. The study showed that the tax policy of the analysed municipalities was differentiated and could, under certain conditions, give rise to a positive upward tendency of incomes generated in property tax – which should be seen as an original contribution of work from the authors of this article.

Purpose The first purpose of the present study is to investigate the coverage of journal articles in Physics in various sources of altmetrics. Secondly, the study investigates the relationship between altmetrics and citations. Finally, the study also investigates whether the relationship between citations and altmetrics was stronger or weaker for those articles that had been mentioned at least once in the sources of altmetrics. Design/methodology/approach The journal articles in Physics having at least one author from an Indian Institution and published during 2014–2018 in sources of altmetrics have been investigated. Altmetric.com was used for collecting altmetrics data. Spearman’s rank correlation coefficient (ρ) has been used as the data found to be skewed. Findings The highest coverage was found on Twitter (22.68%), followed by Facebook (3.62%) and blogs (2.18%). The coverage in the rest of the sources was less than 1%. The average Twitter mentions for journal articles tweeted at least once was found to be 4 (3.99) and for Facebook mentions, it was found to be 1.48. Correlations between Twitter mentions–citations and Facebook mentions–citation were found to be statistically significant but low to weak positive. Research limitations/implications The study concludes that due to the low coverage of journal articles, altmetrics should be used cautiously for research evaluation keeping in mind the disciplinary differences. The study also suggests that altmetrics can function as complementary to citation-based metrics. Originality/value The study is one of the first large scale altmetrics studies dealing with research in Physics. Also, Indian research has not been attended to in the altmetrics literature and the present study shall fill that void.
