Background: Diabetes is a global epidemic with serious complication and there is a clear need for paying special attention to self-management as the cornerstone to optimal control of the disease. Objectives: This study aimed to assess the self-management status and its correlation to disease control indicators in people with diabetes. Methods: In a descriptive cross-sectional study, 220 patients were selected from the list of the referred patients available in Lamerd public health network from December 2014 to June 2015. In the first step, data about demographic information and disease control were collected from the patients’ records. In the second step, the self-management status of each patient was assessed by the Diabetes Self-Management Questionnaire developed by Schmitt et al. To analyze the data, independent sample t-test and Pearson correlation coefficient were used. Results: The mean age of the male and female participants was 56.43 ± 13.50 and 56.46 ± 10.49 years old, respectively. The mean duration of the disease was 6.67 ± 4.72 years for men and 7.07 ± 5.30 years for women. Twenty-one (25.9%) men and 60 (43.7%) women had a history of smoking. The results of the Pearson correlation coefficient showed that there was an inverse and statistically significant relationship between diabetes self-management status and weight, body mass index (BMI), waist circumference, glucose tolerance test (GTT), LDL, and cholesterol. The results of the t-test did not show significant differences between the level of HbA1C (HbA1C7) and self-management scores of the patients (P > 0.05). Conclusions: Patients with better self-management status were in a better disease control condition with respect to weight, BMI, waist circumference, GTT, LDL, and cholesterol levels. Special attention to the control and management of LDL, cholesterol, HbA1C, BMI, and blood pressure levels is recommended in planning for these patients.

ABSTRACT Purpose To determine the variations in average distances between various facial landmarks used to determine the vertical dimension of rest and occlusion among dentulous and edentulous subjects. Besides determining the reliability of these facial measurements against commonly used Chin-Nose distance, this study would also compare the difference between cephalometric landmarks (anterior nasal Spine-Menton) with the Chin-Nose distance (Niswonger's method). Materials and methods To standardize the measurement and minimize errors associated with observer and subject movement, a novel instrument was designed in the form of an apparatus and was named as subject and device stabilizing apparatus (SDSA). One hundred and twenty subjects, in the age group of 30 to 60 years, were selected and divided into two equal groups which were further subdivided into subgroups. Measurements were recorded with the help of a digital vernier that was attached to the apparatus. The various facial measure- ments studied were Pupil-Stomion, Glabella-Subnasion, Pupil-Pupil and Angle-Angle both at rest and in occlusion. These measurements were then compared with Chin-Nose and anterior nasal Spine-Menton distance. Differences between the dentulous and edentulous subjects at rest and at occlusion were noted and statistically analyzed using unpaired ‘t’ test and Karl Pearson correlation coefficient. Results Among the six measurements Chin-Nose, Glabella- Subnasion, Pupil-Stomion and anterior nasal Spine-Menton were closely associated between dentulous and edentulous subjects both at rest and at occlusion. Among all facial and cephalometric measurement the facial parameter of Pupil- Stomion illustrates the least deviation in edentulous (1.318) and dentulous (1.381) subjects at rest, whereas anterior nasal Spine-Menton displays least deviation in edentulous (2.751) and dentulous (1.224) subjects at occlusion. Conclusion The average facial measurements in dentulous subjects were more than measurements in edentulous subjects and among various facial measurements, Pupil-Stomion and anterior nasal Spine-Menton distance can be used clinically as a guide to verify vertical dimension of occlusion.

The Impact

This chapter contributes to the study of uncertainty of signal dimensions within a microscopic image of blood sample. Appropriate colocalization indicator classifies the leukocytes in the region of interest having ragged boundaries. Signal transduction has been interpreted using correlation function determined fluorescence intensity in proposed work using just another colocalization plugin (JaCoP). Dependence between the channels in the colocalization region is being analysed in a linear fashion using Pearson correlation coefficient. Manders split, which gives intensity, is represented in a channel by co-localizing pixels. Overlap coefficients are also being analysed to analyse coefficient of each channel. Li's intensity correlation coefficient is being used in specific cases to interpret the impact of staining.

In today's world, human capital is considered as the highest and most valuable asset of an organization, which affects the profits and losses of any company. The organizations that exist in these societies must be able to utilize human resources effectively. Job rotation is one of the management measures in the field of human resource management. It can create a creative, ideal, and secure organization that ensures commitment, knowledge transfer, skills acquisition, innovation, creativity, experience, job satisfaction, enthusiasm, exhaustion reduction, and human capital growth. The aim of this study is to investigate the effect of job rotation system on work motivation (studied in the region of two gas transfer operations). The present study is a correlation from the field and in terms of purpose and nature of application and in terms of descriptive-survey method and in terms of cross-sectional time. The statistical population of the study is 850 personnel (managers, experts and employees) of the region of two gas transmission operations. Using Cochran's formula, the sample size for limited communities is 285 people. The statistical population of the study consists of heterogeneous groups (formal and informal forces, managers and employees) using stratified random sampling method. In order to collect data, a researcher-made questionnaire with 20 items and a standard job motivation questionnaire with 17 items were used. The questionnaire is divided based on a five-point Likert scale. Reliability and validity were calculated and the value of 0.881 was obtained, which indicates the appropriate reliability of the questionnaires. To investigate the relationship and research hypotheses, Pearson correlation coefficient and regression, SPSS software and LISREL software were tested. The results show that the dimensions of job rotation such as human capital development and changes in human capital are related to work enthusiasm. Pearson correlation coefficient is 0.842 and 0.368, respectively, which indicates a good correlation. Also, the development and changes of human capital have a significant effect on job motivation and the standard beta value was 0.343 and 0.281, respectively, and all research hypotheses have been confirmed.

Speed is a main factor affecting the kinematic of snow-sports accidents and the degree of severity of the resulting injuries. The aim of this study was to measure on-slope actual maximum speeds of snowboarders and to assess their ability to accurately them with regard to individual factors such as gender, skill level, age and risk-taking behaviour and actual maximum speed. The data were obtained from a sample of 312 (67% male, 33% female) adult recreational snowboarders taking lessons in one of the major resorts in the Spanish Pyrenees. The Pearson correlation coefficient was used to investigate the relationship between maximal measured actual speed and estimated speed for all participants. Multiple linear regression analysis was used to estimate the impact of individual factors on both the snowboarders’ actual maximum speed and their error of estimation. The Pearson correlation coefficient between estimated and actual maximum speed was 0.52 (P < 0.001) for all participants. They underestimated their actual maximum speed on average by 10.05 km/h or 28.62%. All assessed factors were shown to significantly affect the snowboarders’ actual maximum speed. However, gender, skill level, age and actual maximum speed were shown to significantly affect the snowboarders’ error of estimation, while risk-taking behavior did not. Gender, skill level, age and risk-taking behaviour are associated with the actual maximum speed at which snowboarders ride, while the same individual factors, except for risk-taking behaviour, and their snowboarding speed seem to affect the ability to estimate actual maximum speeds in adult recreational snowboarders. The ability to estimate actual speed accurately is an important factor to avoid accidents on ski slopes and, therefore, having snowboarders informed about the benefits of speed self-awareness is a key matter for prevention purposes.

The purpose of the article. The aim of the study is to show the impact of the key macroeconomic determinants of the credit risk of the banking sector in Poland in 2011–2020. This aim was achieved by analysis of the Pearson correlation coefficient and econometric models allowing to determine the impact of individual variables on the NPL index. Methodology: The empirical part includes the presentation and description of basic descriptive statistics, as well as the calculation of the Pearson correlation coefficient with the interpretation of the obtained results. The dynamic econometric model describing the variability of the NPL ratio was built using mainly macroeconomic variables. Results of the research: Research has shown the impact of changes in the unemployment rate and the inflation rate on credit risk. On the other hand, the impact of economic growth on the NPL ratio in the analyzed period was not statistically significant. The relationship between credit risk and changes in foreign exchange rates (CHF, USD, EUR) turned out to be negative in the analyzed period, which means that the increases in exchange rates of these currencies did not result in a significant burden of credit risk in the banking sector in Poland.

BACKGROUND Health sciences are steadily developing apps to help people to have a correct lifestyle and, in case of chronic diseases, to help physicians to follow their patients. However, a proper validated tool to evaluate patients’ perception of apps’ usefulness, graphic and comfort to use it still lacks in many languages. At present time, there is an English validated questionnaire called User Version of the Mobile Application Rating Scale (uMARS). OBJECTIVE Aim of the study is to translate and validate uMARS in Italian. METHODS uMARS questionnaire have been translated into Italian by an official translator from English. Then, questionnaire has been administrated to 100 smartphone users to evaluate the same App at time 0 and at time 1 (after 2 weeks). Paired t test, Pearson Correlation Coefficient,Intraclass Correlation Coefficient (ICCs) and Cronbach’s Alpha were used to evaluate Italian uMARS reliability and validity. RESULTS Subjects were 100, 52 male (52%) and 48 females (48%). Mean age was 22.8 (SD: 3.4). All the enrolled subjects answered to all questions both at time 0 and at time 1. Paired t test showed no statistically significant difference for each answer or answers group between time 0 and 1 (P>0.05). In detail, higher variability was observed for question E20, regarding the subjective evaluation of the app: “What is your overall (star) rating of the app?” T0 mean 3.7 (SD: 0.8) vs T1 mean 3.6 (SD:1.0) p=0.089. The lower variability was observed in the Information Section for question D16 “Credibility of source: does the information within the app seem to come from a credible source? “, T0 mean 3.6 (SD:1.1) T1 mean 3.6 (SD: 1.1) p=1.000. Cronbach’s alpha was 0.945, as all patients answered to all questions. Each question was furtherly assessed through Pearson correlation coefficient, which demonstrated high reliability, with significant P (<0.05) and Pearson Coefficients higher than 0.7. Similarly, ICC, which was always higher than 0.750, confirmed an excellent test-rest reliability. CONCLUSIONS Our results allow the validation of uMARS in Italian language and it may become a reliable and useful tool to evaluate health app
