We study the weakness of key schedules from an observation: many existing attacks use the fact that the key schedules poorly distribute key bits in the diffusion path of round function. This reminds us of the importance of the diffusion’s relation between key schedule and round function. We present new cryptanalysis results by exploring such diffusion relation and propose a new criterion for ne...

This work describes the application of the schedule-based approach when dealing with the Grid scheduling problem. We present the advantages as well as the common problems related to this approach. In contrast to the classical queue-based approach, schedule-based approach is much more influenced by the natural dynamics and the uncertainty present in the Grid. Therefore, we propose some general t...

conclusions as a result of this study, it was found that critical care nurses with fixed shift schedules display more burnout in emotional exhaustion dimension, compared to those working with rotating shift schedules. results most of the participants were females (62.7%), aged between 22 - 29 years (38.5%), married (59.2%), and had a bachelor degree (86.9%). the mean score of emotional exhausti...

This paper presents a mechanism in developing work-rest schedules for construction labors. Two objectives are balanced in the optimization processes. These objectives include minimizing the time for completing jobs as well as minimizing total extra energy that labors expend due to inappropriate work assignment which forces labors to working longer than maximum acceptable work duration. Experime...

The current research drew upon the resource perspective (Grzywacz & Marks, 2000; ten Brummelhuis & Bakker, 2012) and firstly focused on the reciprocal mediation relationship between schedule control, work interference with family (WIF) and emotional exhaustion. First, the present study proposed that WIF mediates the negative relationship between schedule control and emotional exhaustion, and em...

INTRODUCTION The main purposes of this study were to investigate shift-work-related health problems in 12-h shift schedule and to identify major factors associated with these problems. MATERIALS AND METHODS This cross-sectional study was conducted at 8 petrochemical plants. The study population consisted of 1203 workers (549 shift and 654 day workers). Data on personal details, the shift sche...

This study aimed to analyze the association between the shift work schedule and metabolic syndrome (MetS). This is a retrospective longitudinal study based on the 2015 health checkup data of 2,090 workers evaluated for MetS in 2010 at a general hospital in Korea. The participants were divided according to their shift work schedule into daytime, three-shift (8-h rotation), and two-shift (12-h ro...

In the current career climate characterized by change and turbulence, employees may demonstrate limited organizational commitment to their employers. Rousseau (1998) suggests that two key ways to elicit loyalty from employees today are to reinforce perceptions of organizational membership and demonstrate organizational care and support for employees. Based on her conceptual framework, we examin...

BACKGROUND Shift work is associated with an increased rate of cardiovascular diseases and accidents. Discordance between circadian rhythms of stress-related biological variables and the work-sleep schedule might explain the reduced efficiency of work. It is not clear whether a shift schedule of work may induce similar discordance in the 24-hour oscillatory pattern of the cardiac autonomic contr...
