conclusions the study findings highlight the importance of the mental aspect of fatigue in this working group. these results have possible implications for workers’ health and well-being and for the design of shift work systems, for industrial workers. background shift work is a well-recognized occupational health hazard in both industrialized and industrially developing countries. prolonged wo...

background: fatigue is one of the most common symptoms in primary care that adversely affects work, family life, and social relations. the purpose of this study was to survey the relationship between work schedule and fatigue among the emergency personnel of isfahan, iran using the checklist individual strength (cis) standard method in 2010. methods: this cross-sectional study was performed on ...

aim. this study was conducted to examine the effect of acupressure on severity of pain and fatigue in patients with chronic heart failure. background. patients with chronic heart failure experience high levels of pain and fatigue. acupressure is a simple, inexpensive and non-invasive method which may reduce the pain and fatigue in patients with chronic heart failure. method. in this single blin...

This paper describes a generic model for predicting the migration of 137 Cs and 90 Sr through complex catchments and the effects of countermeasures to reduce the contamination levels. The model provides assessments of radionuclide behaviour in water systems comprised of rivers, lakes and reservoirs. It makes use of aggregate, “collective” parameters which summarise the overall effects of compet...

This study aimed at clarifying the issues of the system that needs to be improved in order to raise the precision of computer-assisted ICD-10 encoding, by analyzing the inconsistency between the codes registered by physician and encoded by experts in discharge summaries of the electronic patient record system. It was found that human related factors led to the major inconsistency at the chapter...

We investigate the reliability of current generation eavesdropping tools and show that obtaining “high fidelity” transcripts is harder than previously assumed. Even in situations highly favorable to the eavesdropper, simple unilateral countermeasures are shown to be sufficient to prevent all tested systems from reliably reconstructing communicated messages. Less than a third of the tested syste...

Logical attacks on smart cards have been used for many years, but their attack potential is hindered by the processes used by issuers to verify the validity of code, in particular bytecode verification. More recently, the idea has emerged to combine logical attacks with a physical attack, in order to evade bytecode verification. We present practical work done recently on this topic, as well as ...

China’s automobile industry has made great progress and contributed a lot to national economic development, but the problems such as dispersion, small, disorderly, worse" in the industry is still very serious. Starting from the SCP paradigm theory in China’s automobile industry, the article analyses the problems including the market structure, market conduct and market performance in China’s au...

The use of geolocation databases for enabling spectrum sharing in the TV bands has been mandated by the Federal Communications Commission (FCC), and it is very likely to be adopted for other spectrum sharing applications as well. Although using geolocation databases is a practical approach for enabling spectrum sharing, it poses a potentially serious privacy problem. Secondary users (queriers),...

It is widely accepted that higher-order masking is a sound countermeasure to protect implementations of block ciphers against side-channel attacks. The main issue while designing such a countermeasure is to deal with the nonlinear parts of the cipher i.e. the so-called s-boxes. The prevailing approach to tackle this issue consists in applying the Ishai-Sahai-Wagner (ISW) scheme from CRYPTO 2003...
