Cardiac response to Nage no Kata in judo

2021

The first world judo Kata competition was held in October 2007 in Tokyo, Japan. The Nage no Kata was developed in 1884 and 1885 at the Kodokan. by Jigoro Kano, the founder of judo, who developed Kata to demonstrate the principles of judo and to provide a type of training which emphasized performing techniques under controlled setting. According to Kano, to fully develop judo skills, it is essential to involve both Randori and Kata techniques [1]. Most highgrade Japanese judo teachers emphasize the importance of Kata performance for judokas’ development, in particular Nage no Kata [2]. Results of the study conducted by Canestri et al. [3] suggested that session-RPE and HR monitoring is a sim…

Identification and quantification of carotenoids including geometrical isomers in fruit and vegetable juices by liquid chromatography with ultraviole…

2004

A method was established for the identification and quantification of carotenoids including geometrical isomers in fruit and vegetable juices by liquid chromatography with an ultraviolet−diode array detector, using a C18 Vydac 201TP54 column. The mobile phase used was the ternary methanol mixture (0.1 M ammonium acetate), tert-butyl methyl ether and water, in a concentration gradient, and a temperature gradient was applied. Retinol palmitate was added as an internal standard. An extraction process (ethanol/hexane, 4:3, v/v) was performed, followed by saponification with diethyl ether/methanolic KOH (0.1%, w/v, BHT) (1:1, v/v) for 0.5 h at room temperature. Seventeen different (cis and trans…

Maternal cell phone use during pregnancy and child cognition at age 5 years in 3 birth cohorts

2018

Background: There have been few studies of children's cognitive development in relation to mothers' cell phone use, and most were limited to outcomes at age 3 years or younger. We examined the relationship between maternal cell phone use during pregnancy and cognitive performance in 5-year old children. Methods: This study included data from 3 birth cohorts: the Danish National Birth Cohort (DNBC) (n = 1209), Spanish Environment and Childhood Project (INMA) (n = 1383), and Korean Mothers and Children's Environment Health Study (MOCEH) (n = 497). All cohorts collected information about maternal cell phone use during pregnancy and cognitive performance in children at age 5. We performed linea…

Safety culture assessment in high reliability organizations: the use of questionnaires in the nuclear industry

2017

El objetivo principal de esta tesis es proporcionar una visión general de las formas actuales de entender, tratar, y evaluar la cultura de la seguridad (poniendo un énfasis particular en la industria nuclear y en la utilización de cuestionarios), y proporcionar orientación a los investigadores y profesionales sobre cómo capturar la cultura de seguridad de las centrales nucleares. Para ello, la tesis actual incluye los siguientes capítulos: CAPÍTULO I - Se presenta una breve introducción a la industria nuclear. Asimismo se presentan algunos de los más destacables pros y contras de la energía nuclear, y desafíos importantes a los que la industria nuclear se estado enfrentando en los últimos a…

Immediate Nonfunctional Loading of NobelPerfect Implants in the Anterior Dental Arch in Private Practice - 5-Year Data

2012

Background: The concept of scalloped implants to maintain the natural contour of the alveolar ridge has been a source of controversy for many years. Purpose: This study examined the long-term clinical performance of the scalloped NobelPerfect implant in a one-stage procedure (immediate loading in the esthetic zone). Materials and Methods: In 20 patients, immediate prosthetic restorations were placed on 31 NobelPerfect implants in a private practice and followed for up to 78 months. Twenty-one implants were placed immediately after extraction, seven implants were placed after osseous consolidation of the extraction sockets, and three implants were placed secondary to extended alveolar ridge …

Semaphorin 6A Improves Functional Recovery in Conjunction with Motor Training after Cerebral Ischemia

2010

Stroke is a major health problem in industrialized societies. Despite numerous attempts at developing acute stroke therapies aimed at minimizing acute infarct development, the only approved therapy so far is recombinant tissue plasminogen activator (rtPA). In recent years, the attention of the stroke community has therefore also put increased emphasis on understanding processes of post-stroke recovery, and their potential exploitability for therapeutic purposes. The brain has a remarkable ability to adapt to changes after stroke. Mechanisms that contribute to this plasticity are re-mapping and expansion of cortical areas to neighboring regions of functional motor cortex areas after injury […

Revisiting the happy-productive worker thesis from a eudaimonic perspective: a systematic review

2021

The happy-productive worker thesis (HPWT) is considered the Holy Grail of management research, and it proposes caeteris paribus, happy workers show higher performance than their unhappy counterparts. However, eudaimonic well-being in the relationship between happiness and performance has been understudied. This paper provides a systematized review of empirical evidence in order to make a theoretical contribution to the happy-productive worker thesis from a eudaimonic perspective. Our review covers 105 quantitative studies and 188 relationships between eudaimonic well-being and performance. Results reveal that analyzing the eudaimonic facet of well-being provides general support for the HPWT…

On the Performance of Channel Assembling and Fragmentation in Cognitive Radio Networks

2014

[EN] Flexible channel allocation may be applied to multi-channel cognitive radio networks (CRNs) through either channel assembling (CA) or channel fragmentation (CF). While CA allows one secondary user (SU) occupy multiple channels when primary users (PUs) are absent, CF provides finer granularity for channel occupancy by allocating a portion of one channel to an SU flow. In this paper, we investigate the impact of CF together with CA for SU flows by proposing a channel access strategy which activates both CF and CA and correspondingly evaluating its performance. In addition, we also consider a novel scenario where CA is enabled for PU flows. The performance evaluation is conducted based on…

Development and validation of a pressurized liquid extraction liquid chromatography–tandem mass spectrometry method for perfluorinated compounds dete…

2009

Abstract This paper describes the development and validation of an analytical methodology to determine eight perfluorinated compounds (PFCs) in edible fish using pressurized liquid extraction (PLE) with water and solid-phase extraction (SPE) with an ion-exchanger as extraction and pre-concentration procedures, followed by liquid chromatography–quadrupole-linear ion trap mass spectrometry (LC–QqLIT–MS). The rapidity and effectiveness of the proposed extraction procedure were compared with those most commonly used to isolate PFCs from fish (ion-pairing and alkaline digestion). The average recoveries of the different fish samples, spiked with the eight PFCs at three levels (the LOQ, 10 and 100…
