BACKGROUND Functional dyspepsia (FD), which is a very common disorder worldwide, is known to be caused by multiple factors including environmental and genetic factors. Sasang constitutional medicine (SCM) is a component of traditional Korean medicine that emphasizes inherited characteristics of the physical and psychological patterns of a patient. This study investigated whether the prevalence ...

Cachexia is a syndrome associated with many chronic diseases and is an independent risk factor for mortality. Yet it is only in these last years that cachexia has received increasing attention, as the recently instituted international congress on this topic indicates. Here we review some of the most noteworthy contributions presented at the 4th Cachexia Conference in December 2007. Of particula...

The most efficient algorithms for solving the single-criterion {0, 1}-knapsack problem are based on the core concept (i.e., based on a small number of relevant variables). But this concept is not used in problems with more than one criterion. The main purpose of this paper is to validate the existence of such a set of variables in bi-criteria {0.1}-knapsack instances. Numerical experiments were...

The task of developing information technology (IT) solutions that consistently and effectively apply security principles has many challenges, including: the complexity of integrating the specified security functions within the several underlying component architectures found in computing systems, the difficulty in developing a comprehensive set of baseline requirements for security, and a lack ...

This paper focuses on estimating clustering validity by using logistic regression. For many applications it might be important to estimate the quality of the clustering, e.g. in case of speech segments’ clustering, make a decision whether to use the clustered data for speaker verification. In the case of short segments speakers clustering, the common criteria for cluster validity are average cl...
