in today’s advanced world resulting from the improvement of technology, societies tend to encounter a large number of problems and accidents. as we know, university’s security personnel are classified as shift workers and are exposed to health disturbing factors. the aim of this study was investigation of shift work disorders among security personnel of the hospitals affiliated to shiraz univer...

Previous research and theory (Crocker & Wolfe, 2001; Kernis, 2003) suggests that adaptive self-esteem stems from just being oneself, and is characterized by a sense of authenticity (SOA). Maladaptive self-esteem is derived from meeting external standards and social comparisons, and is characterized by a sense of superiority (SOS). Thus, the qualitative difference between SOA and SOS depends on ...

OBJECTIVE The purpose of this study was to explore the influence of age, menopause, anthropometry, nutrition and lifestyle on bone status of women of the Northern Mediterranean Region ofCroatia, which is considered the Adriatic Coast of Southeast Europe. METHODS Quantitative ultrasound measurement was performed on the women's right heel and the values of the primary parameters (the Broad Ultr...

BACKGROUND It seems to be important to recognize predictors of bone health condition in Japanese super-aged society. The purpose of this study was to investigate predictors of the speed of sound (SOS) of calcaneus by quantitative ultrasound measurements of mountain village residents. MATERIALS AND METHODS Medical examinations were conducted on 214 participants (69 men, 145 women; average age ...

System of Systems (SoS) is an emerging paradigm by which independent systems collaborate sharing resources and processes to achieve objectives that they could not on their own. In this context, a number emergent behaviors may arise can undermine the security constituent systems. We apply Delphi method with aims improve our understanding SoS related problems, investigate possible causes remedies...

Increased sebum production is a common skin complaint and plays an important role in acne and oily scalp conditions. To choose the correct skin care products, which mostly are marketed for dry, oily or normal skin, the consumer must self-assess their skin type. Studies show that individuals incorrectly self-assess their sebum secretion levels. In order to be able to correctly determine skin oil...

SoS Models used for SoS design and requirements elicitation. At runtime operations SoS is under failure risk that resulted from its emergent behavior due to its constituent systems autonomy and system complexity. In order to mitigate SoS failure effects and prevent SoS failure we propose SoS model extensions and system failure prediction and prevention framework that enhance the usage of SoS st...

Modular SOS (MSOS) is a simple variant of conventional Structural Operational Semantics (SOS). Using MSOS, the transition rules for each construct of a programming language can be given definitively, once and for all, and never need reformulation when further constructs are added to the language. MSOS thus provides an exceptionally high degree of modularity in language descriptions, thereby rem...

Structured Operational Semantics (SOS) is a popular method for defining semantics by means of transition rules. An important feature of SOS rules is negative premises, which are crucial in the definitions of such phenomena as priority mechanisms and time-outs. However, the inclusion of negative premises in SOS rules also introduces doubts as to the preferred meaning of SOS specifications. Order...
