rapy in the formation of hardiness and to delve deeper into the relationship between hardiness and actual capabilities of the person. Data were collected from 380 people from Ukraine, aged between 19 and 62. The respondents completed the Wiesbaden Inventory for Positive Psychotherapy and Family Therapy (WIPPF 2.0), which was developed by N. Peseschkian in collaboration with H. Deidenbach and the Maddi Hardiness Scale. We used Pearson’s correlation coefficient to measure the statistical relationship between hardiness and personal capabilities. Also, we used regression analysis to determine the prognostic indicators for hardiness. As a result of our research, we found that the capabilities of contact, trust, hope, love, achievement, and reliability have the greatest influence on hardiness

The Relationship

Studying the relationship between two quantitative variables is a standard topic in statistics. In high school and introductory college-level statistics, Pearson's correlation coefficient, r, is typically included as a measure of the direction and strength of the linear relationship between two quantitative variables. This article describes an activity that aids an intuitive development of the formula for r and its interpretation. Exploring scatter plots allows students to develop an intermediate measure of association called the quadrant count ratio (QCR), investigate properties of the QCR, and develop Pearson's r to address some of the QCR's shortcomings.

Introduction: Selection of the maxillary anterior teeth is one of the most crucial steps in fabricating a removable prosthesis. To overcome this challenge, the relationship between facial measurements and natural teeth could be used as a guide in selecting the Maxillary Central Incisor (MCI) teeth. To improve aesthetics, various efforts have been made to associate the Mesiodistal Dimension (MD) of the MCI with various facial parameters. Aim: To determine the relationship between Bizygomatic Width (BZW) and the MD of the MCI in the Saudi population. Materials and Methods: The cross-sectional study selected two hundred dentulous subjects (100 males and 100 females) using a simple random sampling technique from December 2019 to March 2020. BZW was measured between the two most prominent points on the zygomatic bone, and the MD of the MCI was measured between the interproximal contact points. Both measurements were made with the help of a digital vernier caliper. Descriptive statistics and student’s t-test were used to compare all the measurements between males and females with a level of significance at 5% (0.05) and the power of the study of 95%. Pearson’s correlation coefficient (r) was used to find the interconnection between MD of MCI and BZW by linear correlation analysis. Results: The average values for BZW for males and females were found to be 123.56±3.74 mm and 117.33±3.21 mm, respectively. The average MD values of MCI for males and females were found to be 8.6±0.46 mm and 8.4±0.53 mm, respectively. A statistically significant difference was observed in the mean values of the BZW (p-value<0.001) and MD of MCI (p-value 0.002) when a comparison was done among males and females. The average ratio of MD of MCI to BZW was found to be 0.07±0.004 for males, whereas it was 0.072±0.004 for females and was statistically significant (p-value 0.001). The ratio of MD of MCI to BZW was found to be 1:14 for males and females. Pearson’s correlation coefficient (r) was positive and ranged from 0.067 to 0.007. Conclusion: Males had greater values for BZW and MD of MCI than females. There was an inconsistency when Berry’s biometric ratio was applied and when compared with the actual MD of MCI measurement in the present study. The findings of this study showed that there was a weak positive correlation between the MD of MCI and the BZW.

The paper presents the results of a laboratory experiment of mesophilic single-stage anaerobic digestion performed to verify the possibility of early detection of process instability and reactor overload by evaluating the course of dissolved hydrogen concentration of the main intermediate. The digestion process was run in a Terrafors IS rotary drum bioreactor for 230 days. The substrate dosed on weekdays was food leftovers from the university canteen. At an average temperature of 37 °C, an organic loading of volatiles of 0.858 kg m−3 day−1 and a theoretical retention time of 259 days, biogas production of 0.617 Nm3 kg VS−1 was achieved with a CH4 content of 51.7 vol. %. The values of the established FOS/TAC stability indicator ranged from 0.26 to 11.4. The highest value was reached when the reactor was overloaded. The dissolved hydrogen concentration measured by the amperometric microsensor ranged from 0.039–0.425 mg dm−3. Data were statistically processed using Pearson’s correlation coefficient. The correlation of the hydrogen concentration with other parameters such as the concentration of organic acids was evaluated. The value of Pearson’s correlation coefficient was 0.331 and corresponded to a p-value of 0. The results confirmed a very low limit of the hydrogen concentration at which the microbial culture, especially methanogens, was already overloaded. The amperometric microsensor proved to be rather unsuitable for operational applications due to insufficient sensitivity and short service life. The newly designed ratio of dissolved hydrogen concentration to neutralizing capacity was tested but did not work significantly better than the established FOS/TAC stability indicator.

BACKGROUND: Almost 25%of workers in the European Union suffer from back pain, and 23%complain of muscle pain. Sixty-two percent of workers carry out repetitive operations with their hands or arms, 46%work in painful or tired positions and 35%carry or handle loads. OBJECTIVE: This study aimed to translate, culturally adapt and validate the Italian version of the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ-I). METHODS: Translation and cultural adaptation procedures followed international guidelines. Participants were recruited from among the personnel components of the Italian Air Force, who were between 18 and 65 years old. Cronbach’s alpha and the intraclass correlation coefficient (ICC) were calculated to assess internal consistency and stability, respectively. The CDMQ-I was administered together with the Visual Analogic Scale (VAS), and the validity was evaluated using Pearson’s correlation coefficient. RESULTS: All CDMQ-I items were either identical or similar in meaning to the original version’s items. The scale was administered twice with a retest after seven to 10 days to 66 participants. Cronbach’s alpha was higher than 0.761, and the ICC ranged between 0.737 and 0.952. Pearson’s correlation coefficient showed positive and significant correlations (p >  0.01). CONCLUSIONS: The study produced an Italian version of the CMDQ with good reliability and validity. This scale is a useful tool to investigate the frequency and intensity of musculoskeletal disorders in various categories of workers.

Recently, the application of molecular docking is drastically increasing due to the rapid growth of resolved crystallographic receptors with co-crystallized ligands. However, the inability of docking softwares to correctly score the occurred interactions between ligands and receptors is still a relevant issue. This study examined the Pearson’s correlation coefficient between the experimental monoamine oxidase-B (MAO-B) inhibitory activity of 44 novel coumarins and the obtained GOLD 5.3 docking scores. Subsequently, optimization of the docking protocol was carried out to achieve the best possible pairwise correlation. Numerous modifications in the docking settings such as alteration in the scoring functions, size of the grid space, presence of active waters, and side-chain flexibility were conducted. Furthermore, ensemble docking simulations into two superimposed complexes were performed. The model was validated with a test set. A significant Pearson’s correlation coefficient of 0.8217 was obtained for the latter. In the final stage of our work, we observed the major interactions between the top-scored ligands and the active site of 1S3B.

The work involved a molecular biological technique (ISSR-PCR) using ISSR-primer S-2, with structure (AGC) 6G. Changes in the gastric mucosa in chronic duodenal ulcer disease against the background of severe chronic atrophic gastritis have been analyzed. Noteworthy is the fact that there is a strong correlation between the degree of dysplasia of the epithelium of the gastric mucosa and the mitotic index, the Pearson's correlation coefficient rxy was 0.853, respectively. A strong and very strong correlation relationship between the indicators of the degree of dysplasia of the epithelium of the gastric mucosa by phenotypic characteristics and indicators of DNA typing of samples of the gastric mucosa, the Pearson's correlation coefficient rxy was 0.863, respectively. DNA profiles of the gastric mucosa of patients with duodenal ulcer according to the results of typing by the ISSR-PCR method ranging from 520 to 620 bp. had the character of microsatellite expansions and differed from the profile of the norm, which is evidence of precancerous changes.
