Demanding cognitive tasks are sometimes carried out under stressful conditions. Several studies indicate that whereas severe stress impairs performance, moderate stress can enhance cognitive performance. In this study, we investigated how moderate stress influences the neural systems supporting working memory. We embedded an N-back working memory task in a moderately stressful context, as indic...

The broken bearings and great noise and vibration often occurs with the small sugarcane harvester transfer case when it starts up working. To analyze the startup status of the transfer case conveniently and quickly, the finite element transient structure analysis is carried out. with virtual prototype technology to simulate the transfer case's startup dynamic process and measure the instantaneo...

OBJECTIVE This article aims to examine the role of work stress as a moderating variable in the chronic pain-depression association, as well as sex differences in this link. METHODS The analyses were carried out using the Canadian Community Health Survey Cycle 1.1. Key variables were chronic pain conditions (fibromyalgia, arthritis/rheumatism, back problems, and migraine headaches), work stres...

this study was conducted over a three-year period (1998, 1999 and 2000) to evaluate some drought tolerance indices and their relations with sugar yield in some sugar beet genotypes under early season drought and non-drought conditions. the experimental design was a split plot with a randomized complete block. the main plots consisted of two irrigation regimes: non-stress and water stress in ear...

OBJECTIVE To evaluate the effectiveness of a web-based multimedia health promotion program for the workplace, designed to help reduce stress and to prevent depression, anxiety, and substance abuse. METHODS Using a randomized controlled trial design, 309 working adults were randomly assigned to the web-based condition or to a wait-list control condition. All participants were assessed on multi...

Korea has a short history in research on occupational health like as short history of industrialization. During last four decades, however, Korea has experienced what developed countries have experienced for more than a hundred year. Research on occupational health in Korea has also drastically developed. Since industrialization in 1970s, many workers were exposed to hazardous working environme...
