Abstract:

Comparison of Values of Pearson's and Spearman's Correlation Coefficients on the Same Sets of Data Spearman's rank correlation coefficient is a nonparametric (distribution-free) rank statistic proposed by Charles Spearman as a measure of the strength of an association between two variables. It is a measure of a monotone association that is used when the distribution of data makes Pearson's correlation coefficient undesirable or misleading. Spearman's coefficient is not a measure of the linear relationship between two variables, as some "statisticians" declare. It assesses how well an arbitrary monotonic function can describe a relationship between two variables, without making any assumptions about the frequency distribution of the variables. Unlike Pearson's product-moment correlation coefficient, it does not require the assumption that the relationship between the variables is linear, nor does it require the variables to be measured on interval scales; it can be used for variables measured at the ordinal level. The idea of the paper is to compare the values of Pearson's product-moment correlation coefficient and Spearman's rank correlation coefficient as well as their statistical significance for different sets of data (original - for Pearson's coefficient, and ranked data for Spearman's coefficient) describing regional indices of socio-economic development.

Abstract:

ABSTRACT Objective: This study aimed to analyze the contribution of parental behavior in DF development in preschoolchildren and seek its correlation with the level of DF. Materials and Methods: This study was addressed to preschoolchildren (3–6 years) in Bandung area using qualitative method through interviews with children. Data analysis was done using Spearman's rank correlation to find the correlation of parental behavior and level of DF. Results: Results revealed eight acquisition themes based on the parental behavior; two themes related to negative information, three themes related to direct conditioning, and three themes related to vicarious learning. Statistical analysis showed a significant Spearman rank correlation rs0.42% or 17.38% (P < 0.01). Conclusion: Parental behavior contributes to the development of DF in children at preschool ages through negative information, direct conditioning, and vicarious learning, as evidenced by the correlation of these parental behaviors with the level of DF in children.

Abstract:

Classification algorithm selection is an important issue in many disciplines. Since it normally involves more than one criterion, the task of algorithm selection can be modeled as multiple criteria decision making (MCDM) problems. Different MCDM methods evaluate classifiers from different aspects and thus they may produce divergent rankings of classifiers. The goal of this paper is to propose an approach to resolve disagreements among MCDM methods based on Spearman's rank correlation coefficient. Five MCDM methods are examined using 17 classification algorithms and 10 performance criteria over 11 public-domain binary classification datasets in the experimental study. The rankings of classifiers are quite different at first. After applying the proposed approach, the differences among MCDM rankings are largely reduced. The experimental results prove that the proposed approach can resolve conflicting MCDM rankings and reach an agreement among different MCDM methods.

Abstract:

Background: The Michigan Hand Outcomes Questionnaire (MHQ) has shown reliability, validity and responsiveness and has been used to assess surgical outcomes mainly in North America. We established a Japanese version of the MHQ and evaluated its reliability and validity compared with both the short-form 36 (SF-36) questionnaire and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire in a Japanese-speaking population. Methods: The MHQ was cross-culturally adapted to a Japanese version according to guidelines. Sixty-eight patients with hand conditions were enrolled in this study and answered the MHQ, DASH questionnaire and SF-36 questionnaire. The MHQ was completed again with an interval of one or two weeks. Reproducibility and internal consistency were statistically assessed by the test-retest method and calculating Cronbach's alpha. Spearman's rank correlation was calculated to assess associations between the MHQ and the SF-36 questionnaire as well as the DASH questionnaire. Results: The intraclass correlation coefficients of MHQ subscales ranged from 0.68 to 0.93. Aesthetics subscale of the left hand showed the lowest intraclass correlation but still a good correlation. Cronbach's alpha values of the MHQ ranged from 0.81 to 0.96 for all subscales. The absolute values of Spearman's rank correlation coefficient between MHQ subscales and DASH function/symptoms scores ranged from 0.49 to 0.82. Spearman's correlation coefficients of the MHQ total score to subscales of the SF-36 questionnaire ranged from 0.42 to 0.68. The strongest correlations were found between work performance of the MHQ and rolephysical of the SF-36 questionnaire. Conclusions: The Japanese version of the MHQ has adequate instrument properties for assessing hand outcomes compared with the SF-36 questionnaire as well as the DASH questionnaire.

Abstract:

In Russia, the downward trends in tuberculosis transmission are leveled by the growing HIV infection spread. In order to improve the situation, it is necessary to know the strengths and weaknesses of tuberculosis control activities among people living with HIV. The objective of the study: the comprehensive assessment of the effectiveness of activities aimed to control the spread of HIV/TB co-infection in North-West Russia. Subjects and methods. The authors used epidemiological and clinical-diagnostic methods, ranking, correlation analysis, and expert assessment. The epidemiological and clinical analyses were based on the reporting forms of Rosstat on tuberculosis and HIV, data from analytical reports on monitoring visits and data from the questionnaires developed by the authors, for 2007-2017. The correlation between the studied parameters was assessed using Spearman's rank correlation. Results. In North-West Russia, the main tuberculosis control activities among people living with HIV, including logistical support and provision of personnel (Spearman's rank ratio (-0.32177), p < 0.05), a set of preventive measures aimed at the coverage with antiretroviral therapy, preventive treatment and screening for tuberculosis in HIV-positive people (Spearman's rank ratio (-0.03226), p > 0.05) did not provide any statistically significant impact on the spread of HIV/TB co-infection, which indicated of their imperfection and inequality. Conclusion. In the North-West of Russia, the system aimed to control the spread of HIV/TB co-infection requires some optimization.

Abstract:

In this study 57 deans in 67 United States and Canadian Dental Schools ranked, in decreasing order of importance, 12 performance criteria and then ranked the same 12 criteria as they perceived faculty would rank them. Agreement between the deans' two global rankings gave a Spearman's rank-order correlation of .92. Although the general level of agreement between the two perceptual ranks was significant, several important discrepancies in rank order were identified. Deans perceived that faculty would rank number of publications first and classroom, clinical, and laboratory teaching third. Deans personally ranked classroom, clinical, and laboratory teaching as first and number of publications as fourth. Implications of the discrepancy between the perceived importance of research productivity and teaching in faculty evaluation were discussed with respect to the increasing emphasis placed on research for dental faculty within the university.

Abstract:

Construction projects are getting progressively complex and their scales are getting sophisticated. Along these lines, it is getting more problematic to finish the projects inside planned cost limits. In Oromia public building construction projects these problems were raised as a typical challenge. Hence, evaluation of factors affecting the accuracy of cost estimation in public projects was the aim of this study. Both quantitative and qualitative methods were utilized for information assortment. Relative Importance Index (RII) was utilized for information investigation. Totally sixty -two variables were investigated and the best five most significant were selected by this assessment based on the average view of respondents. These significant factors are; Material price/accessibility /source /quality /imports, Experience and ability of the consultant, Variability in the Economy of the country, and financial conditions of client. Spearman's rank correlation coefficients (rho) investigation was conducted by the assistance of SPSS 20 version for a testing level of connections among respondents on the positioning of the factors affecting the accuracy of cost estimation. Spearman’s rank correlation results were 0.823 among Clients and Consultants, 0.813 among clients and contractors, and 0.802 among Consultants and Contractors. The outcome shows that the rate of the rank correlations was a high positive number, which implies there is a positive connection between them on the ranking of factors disturbing the accurateness of cost estimation in public building construction projects in western Oromia.

Abstract:

Intelligence are things related to intelligence, intellectual action, and perfect development of the mind. Every human being has the right to develop himself based on intelligence. A child who is good at playing violin shouldn't let himself feel like he is stupid because he is unable to complete his mathematical tasks. Therefore, the author wants to create a system for determining children's talent based on multiple intelligence as measured by the tendency of posts about their daily activities on social media by using the Sentistrength and Spearman's Correlation Coefficient methods. The purpose of this research is to create a social media application called Juicer, which is able to determine one's talent according to multiple intelligence theory based on data in the form of user posts about their daily activities. Users input their daily activities and opinions about the activities that he is currently undergoing. The system will analyze the data entered a negative or positive opinion. Then determine whether the data entered are musical-rhythmic, visual-spatial, verbal-linguistic, logical-mathematical, bodily-kinesthetic, interpersonal, intrapersonal, naturalistic, and / or spiritual-type using lexicon-based sentiment analysis with the Sentistrength method. After a long period of time, the system will sort the data that has been stored. After the data is classified, user intelligence types will be found based on multiple intelligence theory, as a result of this study. The result of the correlation between intelligence type data obtained through the system compared to intelligence type data obtained through the manual method is 80%, and the deviation value is 0.09.

Abstract:

High levels of FFA have been a recurring problem in the seed oil of Ontario-grown, canola-quality summer rape (Brassica napus L.). Examination of seed samples from the Eastern Canadian Co-operative Cultivar Trials conducted at several locations in 1988–1993 showed significant, consistent differences in FFA levels among cultivars. In each year from 1988 to 1991 the cultivars Kristina, Delta and Westar had FFA levels that were about 40% of those of Global and the triazine-tolerant cultivars Stallion, OAC Triton and OAC Triumph. Pearson's correlations and Spearman's rank correlation between years for FFA levels of genotypes were all significant, with the exception of the Spearman's rank correlation between 1992 and 1993. Significant differences in FFA occurred among locations in southern Ontario, but location differences were not consistent across years. Cultivars grown in western Canada, however, had FFA levels between 2 and 41% of their FFA levels at the southern Ontario locations. The FFA levels of cultivars at one Ontario location were significantly correlated with the mean FFA levels of the same cultivars from all the other Ontario locations in the same year, 28 out of 34 times. Correlations were higher before the high-FFA cultivars were removed from the trials in 1991. Screening of lines in a breeding program for susceptibility to high FFA at one southern Ontario location appeared to be predictive of FFA levels at other southern Ontario locations. Selection of cultivars that have low FFA levels should reduce the FFA problem in Ontario-grown spring canola. Key words:Brassica napus, canola, free fatty acids, cultivars, stress, environment

Abstract:

Marketability of livestock production was analyzed based on the marketability of both pork, beef, sheep and poultry and eggs and cow's milk. The sequential order of the Vojvodina municipalities according to the observed denominators is not identical. But, Spearman's coefficient of correlation points to a statistically very high degree of accordance between the rank-list of marketability of pork and the rank-lists of marketability of beef, poultry and milk as well as the rank-list of poultry and sequential classification of sheep meat and eggs, beef and milk. There was a statistically high correlation between the rank list of marketability of sheep meat and pork, beef and milk as well as poultry and milk. Based on the value of Kendal coefficient of ranking, it can be concluded that there exists very high degree of accordance of all the rank lists being observed simultaneously. For determination of sequential classification according to the achieved marketability of all the analyzed livestock production commodities in the sense of synthetic denominator, Ivanovic distance was used in the present work.

Abstract:

Background Legg-Calvé-Perthes disease (LCPD) is a paediatric form of osteonecrosis that ultimately heals but will cause femoral head and acetabular deformities. The purpose of this study was to investigate the early serum measurement of osteocalcin in children with femoral head necrosis compared with that of healthy children. Methods 20 patients with LCPD (4 girls and 16 boys) and 20 healthy volunteers (5 girls and 15 boys) were enrolled. All patients did not have additional treatment. Blood samples were obtained from all patients pre-operatively in the morning. All cases had hip radiographs. The serum levels of osteocalcin comparisons between the LCPD patients and the healthy volunteers were performed using Wilcoxon signed-rank test. The Spearman rank correlation was used to assess correlation between LCPD grade and serum osteocalcin levels. Significance was set at p = 0.05. Results The 20 patients with LCPD (72.75 ± 24.92 ng/ml) had significantly higher serum osteocalcin levels compared with the healthy group (16.80 ± 4.04 ng/ml) (p≤0.01). Serum osteocalcin levels of different LCPD grades were significantly different (Spearman's p = 0.540, p = 0.014). Conclusions We observed a significant correlation between serum osteocalcin levels and LCPD. These results may be meaningful in clinical practice and to future studies.

Abstract:

Abstract Background: Copeptin, the C-terminal moiety of provasopressin, is cosecreted with vasopressin. Copeptin may be a useful parameter to characterize disorders of water homeostasis and can be readily measured in plasma or serum. However, it is unknown to date how circulating copeptin and vasopressin levels correlate at different plasma osmolalites. Objective: To correlate plasma copeptin with plasma osmolality and vasopressin concentrations in healthy subjects during iso-, hypo-, and hyperosmolar states. Methods: Plasma osmolalities, copeptin, and vasopressin levels were measured in 20 volunteers at baseline, after an oral water load, and during and after iv infusion of 3% saline. Correlation coefficients were determined between plasma osmolalites and copeptin and vasopressin concentrations, as well as between vasopressin and copeptin concentrations. Results: Median plasma osmolalities decreased from 290 mOsm/kg (range, 284–302) at baseline to 281 (273–288) mOsm/kg after water load and rose to 301 (298–307) mOsm/kg after hypertonic saline. Median plasma copeptin concentrations decreased from 3.3 (1.1–36.4) pm at baseline to 2.0 (0.9–10.4) pm after water load and increased to 13.6 (3.7–43.3) pm after hypertonic saline. Vasopressin and copeptin concentrations correlated with plasma osmolality (Spearman's rank correlation coefficient 0.49 and 0.77, respectively). There was a close correlation of vasopressin and copeptin concentrations (Spearman's rank correlation coefficient 0.8). Conclusion: Plasma vasopressin and copeptin correlate strongly over a wide range of osmolalities in healthy individuals. Therefore, the measurement of copeptin, which remains stable for several days, is a useful alternative to vasopressin measurements and will likely facilitate the differential diagnosis of disorders of water metabolism.

Abstract:

To evaluate the repeatability of yield-based drought tolerance indices over years, twenty chickpea genotypes were evaluated using a randomized complete block design with three replications for four cropping seasons (2008–2012) in the experimental field of Razi University. The result of combined analysis of variance for seed yield showed significant differences for location (L) (rain-fed and irrigated), genotype (G), and LY and GL interactions, indicating the presence of genetic variability and the possibility of selection for stable, drought-tolerant genotypes. Principal component analysis (PCA) based on the Spearman's rank correlation matrix was used to visualize the relationships between different drought tolerance indices. Due to their positive significant correlation with seed yield under both conditions over four cropping seasons, the stress tolerance index (STI) and geometric mean productivity (GMP) were identified as desirable criteria for the selection of drought-tolerant genotypes under severe stress conditions. The selection of drought-tolerant chickpea genotypes using these indices in a one-year trial will mirror the results of multiple cropping season trials. According to the Spearman's rank correlation coefficients between single vs. single years and single vs. the mean of multiple years, the tolerance index (TOL), mean productivity (MP), abiotic tolerance index (ATI), stress susceptibility percentage index (SSPI) and modified stress tolerance index (K1STI) were identified as repeatable indices under severe drought conditions.

Abstract:

Principal component analysis is one of the methods traditionally used to solve the problem of reducing the dimensionality of a multidimensional vector with correlated components. We constructed the principal components using a special representation of the covariance or correlation matrix of the indicators observed. The classical principal component analysis uses Pearson sample correlation coefficients as estimates of the correlation matrix elements. These estimates are extremely sensitive to sample contamination and anomalous observations. To robustify the principal component analysis, we propose to replace the sample estimates of correlation matrices with well-known robust analogues, which include Spearman's rank correlation coefficient, Minimum Covariance Determinant estimates, orthogonalized Gnanadesikan --- Kettenring estimates, and Olive --- Hawkins estimates. The study aims to carry out a comparative numerical analysis of the classical principal component analysis and its robust modifications. For this purpose, we simulated nine-dimensional vectors with known correlation matrix structures and introduced a special metric that allows us to evaluate the quality of data compression. Our extensive numerical experiment has shown that the classical principal component analysis boasts the best compression quality for a Gaussian distribution of observations. When observations are characterised by a Student's t-distribution with three degrees of freedom, as well as when a cluster of outliers, individual anomalous observations, or symmetric contaminations described by the Tukey distribution are present in the data, it is the Gnanadesikan --- Kettenring and Olive --- Hawkins estimates modifying the principal component analysis that show the best compression quality. The quality of the classical principal component analysis and Spearman’s rank modification decreases in these cases

Abstract:

The study focuses on professional self-determination formation in high school students as a corre-lation between their anxiety and self-esteem is considered to be highly important in the study of human resources. The purpose of the study is to determine on the basis of theoretical arguments a correlation between self-esteem and state anxiety in students in the process of professional self-determination and prove it with an experiment. The study was conducted in Kuzino State School 36 of the Sverdlovsk Region. The study was carried out in three stages: desktop analysis, experimental research, and data analysis. The research comprised empirical methods in the form of an ascertaining experiment and testing, statistical and mathematical methods in the form of Spearman's rank correlation coefficient, and three techniques: the Dembo-Rubinstein technique for self-esteem evaluation modified by A.M. Prikhozhan, the Kazantseva technique for general self-esteem assessment, and the State-Trait Anxiety Inventory, developed by C.D. Spielberger and modified by Yu.L. Khanin. The research on self-esteem of students in the process of professional self-determination showed the following findings. Based on the Dembo-Rubinstein technique, average self-esteem prevails among study subjects (67%); moreover, the Kazantseva technique demonstrated the prevalence of average self-esteem among high school students as well (63%). The State-Trait Anxiety Inventory also showed that most of the subjects (68%) had an average level of anxiety. In the study, experiments were performed and levels of self-esteem and state anxiety in professional self-deter-mination formation were determined; a correlation between self-esteem and state anxiety was proven. Study findings demonstrated that most students had average self-esteem and average state anxiety. Thus, according to Spearman's rank correlation coefficient, there is indeed a correlation between self-esteem and state anxiety in students in the process of professional self-determination.

Abstract:

472 Background: Colorectal Cancer (CRC) is one of the leading causes of death worldwide. MicroRNA-34a (miR-34a), a tumor suppressor gene, is known to be down-regulated in CRC cell lines and recently shown to be a cell-fate determinant in early-stage dividing colon cancer stem cells. However, its prognostic significance is unclear. Methods: MiR-34a detection was performed by in situ hybridization on a CRC tissue microarray (n=127; stage I, 21 patients; II: 42; III: 33; IV: 31). Its expression was graded as negative (no signal), low (expression in 1-19% of cancer cells), moderate (20-49% of cancer cells), and strong (50-100% of cancer cells). The correlations between miR-34a expression and EGFR, osteopontin (OPN), p53, Ki67, LEF1, VEGF, COX2, MMR, stage and grade were evaluated by chi-squared test and Spearman's rank correlation coefficient. Kaplan-Meier survival analysis, log-rank test and Cox regression model were used to assess the association of miR-34a expression with recurrence-free survival (RFS) and disease specific survival (DSS). Results: MiR-34a expression had moderate positive correlation with genes associated with tissue proliferation and invasion, including Ki67 (Spearman's r=0.28, p=0.002), and weak correlation with EGFR (r=0.2, p=0.02) and LEF1 (r=0.18, p=0.039). In the subgroup of patients (n=75; stage II/III) with negative OPN expression (n=25), weak or negative miR-34a expression was associated with worse RFS (HR=4.1; 95%CI=1.1-15.9; p=0.036) and DSS (HR=10.5; 95%CI=1.2-94.5; p=0.036). Conclusions: Our results suggest that down-regulated or absent expression of miR-34a correlates with worse RFS and DSS in stage II - III CRC patients with negative OPN expression. Further investigation of miR34a in prospective randomized studies is warranted to establish its role as a prognostic factor for CRC outcome.

Abstract:

Background: Speech delay is a problem that occurs in society commonly found in children. One of the factors affecting language development is the early sensory perception stimulation.Objectives: This study was purposed to analyze the correlation between early sensory perception stimulation and language development in children aged 12-24 months.Methods: This observational study was conducted using a cross-sectional approach. It involved 34 parents and their children aged 12-24 months as the population, in which 32 parents and their children were taken as the samples using simple random sampling technique. The independent variable was the early sensory perception stimulation, whereas the dependent variable was language development. The instruments used in this study were questionnaire and observation sheets. Furthermore, the collected data were analyzed using Spearman's rank correlation test with the significance level of Î± = 0.05.Results: The results of this study showed that nearly all of the respondents (89.5%) provided their children with the early sensory perception stimulation sufficiently. Consequently, most of the children (62.5%) experienced language development sufficiently. Moreover, the correlation test using Spearman's rank test showed that Sig. = 0.000 (p < 0.05) illustrating that p <Î± so that Ho was rejected. This result showed that there was a correlation between early sensory perception stimulation and language development in children aged 12-24 months.Conclusion: The early sensory perception stimulation which is given well to children will result in optimal language development. Hence, the health workers, especially the nurses, are expected to provide the family with a counseling program about the importance of giving the early sensory perception stimulation to children to optimize their language development.Â Key words: Early sensory perception stimulation, language development.

Abstract:

Purpose A retrospective analysis of tonal and speech loudness discomfort levels (LDLs) relative to a subjective report of sound tolerance (SRST) was performed to explore the relation between the 2 commonly used clinical measures. Method Tonal LDLs and SRST were measured for 139 U.S. military veterans who were recruited into a study providing intervention for tinnitus. Spearman's rank correlation coefficients were computed to assess the relation between the tonal and speech LDLs and the SRST. Results Only weak correlations were found between tonal LDLs and SRST and between speech LDLs and SRST. Conclusion If LDLs ratings of SRST measured the same phenomenon, the measures would be strongly negatively correlated. The weak correlations found between the measures suggest that LDLs do not accurately represent a patient's ability to tolerate sound in daily life.

Abstract:

Ankylosing Spondylitis Disease Activity Score (ASDAS) is a very important tool for measuring disease activity in patients with axial spondyloarthritis (axSpA). This study was aimed to develop a culturally adapted, valid and reliable Bengali version of questionnaire for the ASDAS. The original English ASDAS was translated into Bangla and adapted in the local socio-cultural context, following standard international recommendations. Content validity of the adapted Bangla version was assessed by the item-level & scale level content validity indices (I-CVI & S-CVI). A total 120 patients with axSpA were assessed in the study. For construct validity, correlation between ASDAS with BASDAI, ESR, CRP, Maastricht enthesitis score, physician's global assessment and BASMI was assessed by Spearman's rank correlation coefficient. Internal consistency and test-retest reliability were assessed using Cronbach's alpha coefficient and intraclass correlation coefficient respectively. I-CVI for each item was 1 and S-CVI was 1. ASDAS-ESR and ASDAS-CRP showed strong correlation (Spearman's correlation coefficient >0.5) with BASDAI, ESR, MASES and physician global assessment of disease activity. The scale demonstrated excellent internal consistency (Crohnbach's alpha=0.703) and test-retest reliability (ICC=0.98). The adapted Bangla version of the ASDAS demonstrated acceptable psychometric properties (validity & reliability) in Bangladeshi patients with axSpA. Faridpur Med. Coll. J. Jul 2019;14(2): 62-66

Abstract:

Introduction The objectives were to evaluate a technique, outcome and complications following anterior greater trochanteric with gluteus medius muscle pedicle bone graft (AMG) procedure in the treatment of adolescent and active adult hip disorders. Methods 20 patients (20 hips) with a mean age of 22.7 ± 15.6 (range 10.0-63.5) years who had undergone AMG and been followed up more than 12 months postoperative were retrospectively enrolled in our study. The AMG procedure was performed in conjunction with subcapital osteotomy for slipped capital femoral epiphysis in 12 and open reduction for fracture/dislocation in 8 hips. At the most recent evaluation, patient functional status was rated by the Harris Hip Score (HHS) and radiographic changes were graded according to Tönnis criteria. Complications were defined as Tönnis grade >2 or hip requiring further surgery. Univariate analysis was used to explore factors associated with complications. Spearman's rank correlation coefficient was calculated between HHS and Tönnis grading. Results At mean follow-up of 4.4 ± 2.6 (range 1.1-9.5) years, mean HHS was 87.4. Tönnis grading was rated as 0 in 10 hips, 1 in 5 hips, 2 in 2 hips, and 3 in 3 hips. Avascular necrosis of the femoral head as a complication developed in 3 hips (15%). Clinical parameters including age at surgery, duration of follow-up and diagnosis were not significantly associated with postoperative complications. A negative correlation between HHS and Tönnis grade was shown by Spearman's rank correlation ( rs = −0.49, p = 0.03). Conclusions The AMG can be safely recommended as an adjunct bone graft procedure when performing anterior open reduction of adolescent and active adult hip disorders.

Abstract:

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.

Abstract:

Objective: The voice low tone to high tone ratio (VLHR) is defined as the power ratio of low frequency to high frequency energy obtained by dividing the voice spectrum with a specific cutoff frequency. In a previous study, VLHR correlated significantly with nasalance and perceptual rating of hypernasality for a single vowel. The methodology was optimized in this study by investigating the correlations among other vowels. Design: Voice signals of six sustained vowels vocalized by subjects with hypernasality were collected. Vowel nasalance was obtained with a nasometer, and hypernasality rating scores were provided by two speech-language pathologists. The VLHRs calculated using different cutoff frequencies were correlated with nasalance and hypernasality rating scores. Participants: Eight subjects with hypernasality caused by palatal fistula or velopharyngeal insufficiency. Main Outcome Measures: VLHR, nasalance, and hypernasality rating score. Results: The correlation of VLHR with nasalance and hypernasality rating was most significant using a cutoff frequency of 600 Hz. The correlation of VLHR with nasalance was significant (r = .62, p < .01, Pearson's correlation), as was the correlation of VLHR with hypernasality score (Spearman's rank correlation coefficient = .62, p < .01). Conclusions: VLHR correlated significantly with nasalance and hypernasality in the six sustained vowels and may provide another quantitative index for the evaluation of hypernasality in sustained vowels.

Abstract:

From a study of riparian habitat structure and a quantitive distribution survey of bullfrog, Rana catesbeiana, mink frog, Rana septentrionalis, and green frog, Rana clamitans melanota, in 31 oligotrophic lakes, we looked for, among 18 physiographic parameters, those that could best explain the spatial organisation of the ranid community. The three species cohabitated in 18 lakes, the mink frog and the green frog in 10 lakes without bullfrog, and the bullfrog alone in 3 lakes. These frogs preferentially occupied (i) habitats with medium or high density of emergent vegetation, (ii) areas with extensive floating aquatic vegetation, (iii) muddy and silty areas, and (iv) especially for the green frog, shrubby habitats with ericaceae. Substrates had a poor explicative value. In lakes devoid of bullfrogs, the mink frogs and green frogs were more frequently abundant and showed a more even distribution in the different habitats than when they were sympatric with bullfrogs. A Spearman's rank correlation analysis confirmed the similarity of habitat preferences between the three species and the poor capacity of the habitat structure to predict the ranid community composition.
