Let Mm,n(0, 1) denote the set of all m× n (0,1)-matrices and let G(m,n) = max{detXX : X ∈Mm,n(0, 1)}. In this paper we exhibit some new formulas for G(m,n) where n ≡ −1 (mod 4). Specifically, for m = nt+r where 0 ≤ r < n, we show that for all sufficiently large t, G(nt+r, n) is a polynomial in t of degree n that depends on the characteristic polynomial of the adjacency matrix of a certain regul...

PURPOSE The goal of this study was to characterize the difficulty index of the items in the skills test components of the class I and II Korean emergency medical technician licensing examination (KEMTLE), which requires examinees to select items randomly. METHODS The results of 1,309 class I KEMTLE examinations and 1,801 class II KEMTLE examinations in 2013 were subjected to analysis. Items f...

We propose a new approach to the classical detection problem of discrimination of a true signal of interest from an interferent signal, which may be applied to the area of chemical sensing. We show that the detection performance, as quantified by the receiver operating curve (ROC), can be substantially improved when the signal is represented by a multicomponent data set that is actively manipul...

The purpose of this study was to examine the feasibility and validity of an Athletic Skills Track (AST) to assess fundamental movement skills among 6- to 12-year-old children in a physical education setting. Four hundred sixty-three Dutch children (211 girls, 252 boys) completed three tests: the Körperkoordinationstest für Kinder (KTK) and two Athletic Skills Tracks (AST-1, AST-2). The validity...

BACKGROUND The study examined the measurement quality of a stage algorithm measuring the Four steps from Inactivity to activity Theory (FIT Model). METHODS In a cross-sectional study, stages were assessed in 1012 Chinese university students in terms of physical activity, social-cognitive variables and health outcomes. Main outcome measures were stages of change, self-reported physical activit...

In  this paper  thin  films of  tin sulfide (SnS) were deposited on  the glass substrates using spray pyrolysis method with the substrate temperatures in the range of 400–600℃, keeping the other deposition parameters constant. In  this work  the characteristic of SnS  thin  films  investigated. The XRD pattern and optical transmittance of thin films also are discussed. With the change in concen...

OBJECTIVE To identify the validity and reliability of the Korean version World Health Organization Quality of Life Assessment (WHOQOL)-BREF among people with physical impairments living in a community. METHODS Participants listed in the community-based rehabilitation project were recruited from 45 public health centers. People with brain lesions or physical disabilities were selected. Respond...

BACKGROUND This study introduces a novel self-report instrument to measure children's time-use in physical and sedentary activities and examines the relationships between children's time-use and physical fitness and risks of obesity and diabetes. METHODS The new instrument utilizes a series of timelines, each representing an activity type. 188 children (53% girls) aged 10 to 14 year-old parti...

INTRODUCTION Personality is one of the important domains of psychology, and it is an integration of emotional, cognitive, social and physical properties. In this study, we aimed to assess the applicability of the "Ten-Item Personality Inventory (TIPI)" which measures five basic personality traits in Turkish young people. METHOD Data from a total of 420 participants - 208 male (49.1%) and 212 ...
