In this paper, a novel fiber-optic sensing system based on fiber Bragg gratings (FBGs) to measure foot plantar pressure is proposed. This study first explores the Pedar-X insole foot pressure types of the adult-size chart and then defines six measurement areas to effectively identify four foot types: neutral foot, cavus foot, supinated foot and flat foot. The plantar pressure signals are detect...

BACKGROUND The tribal inhabitants of the Skardu valley (Pakistan) live in an area of great endemic botanic diversity. This paper presents the first quantitative ethnomedicinal spectrum of the valley and information on the uses of medicinal plant. This paper aims to analyze and catalogue such knowledge based on Relative Frequency Citation (RFC) and Use Value (UV) of medicinal plants in addition ...

A method is suggested for estimating the correlation of a naturally (X) and an artificially (Y) dichotomized variable. It is assumed that a normal random variable (L) underlies the artificially dichotomized variable. The proposed correlation coefficient recovers the product moment correlation coefficient between X and L from a fourfold table of X and Y. The suggested correlation coefficient nu ...

For clarity, the Pearson R and R are given in Table 1 below for all the theoretical cases posed. It corrects the correlation coefficients in Figure 3 and in the discussion of signal over noise in the “Strengths and Weaknesses” section. It should be noted that our use of R is based on squaring the Pearson value, not based on a calculation of the coefficient of determination (also called R). The ...

It is more common for educational and psychological data to be non-normal than to be approximately normal. This tendency may lead to bias and error in point estimates of the Pearson correlation coefficient. In a series of Monte Carlo simulations, the Pearson correlation was examined under conditions of normal and non-normal data, and it was compared to its major alternatives, including the Spea...

The purpose of this study was to determine if a pharmacology medical history assignment would enable dental students to demonstrate improved knowledge and understanding of pharmacology by researching the drugs their patients were taking and recording pharmacological information in their patients' health records. The study followed a pretest-posttest design and evaluated students' knowledge of t...

background: one of the factors that can improve self-concept and performance of staff is professional maturity. professional maturity can also solve the problems of self-concept. the purpose of this paper was to identify the relationship between the dimensions of self-concept and professional maturity.   materials and methods: this relative applicable study was performed on all the personnel (n...

It is widely appreciated that many studies in psychological science suffer from low statistical power. One of the consequences analyzing underpowered with thresholds significance a high risk finding exaggerated effect size estimates, right or wrong direction. These inferential risks can be directly quantified terms Type M (magnitude) error and S (sign) error, which communicate design choices on...

Background. Protein dihedral angles provide a detailed description of protein local conformation. Predicted dihedral angles can be used to narrow down the conformational space of the whole polypeptide chain significantly, thus aiding protein tertiary structure prediction. However, direct angle prediction from sequence alone is challenging. Method. In this study, we present a novel method to pre...

A Collaborative Filtering was successfully implemented using the computer programming language Java to produce recommendations between users such that only similar users were considered. Both Mean Squared Difference (MSD) and Pearson Correlation Coefficient (PCC) were used and evaluations carried out on each. The metric which performed best on the u.data file was PCC with L = 0. Conversely, the...
