PURPOSE The purpose of this study was to investigate the anger expression types in nurses and to analyze the differences between the anger expression types and interpersonal problems. METHODS The data were collected from 149 nurses working in general hospitals with 300 beds or more in Seoul or Gyeonggi province, Korea. For anger expression type, the anger expression scale from the Korean Stat...

This paper provides details on the necessary steps to assess and control data in genome wide association studies (GWAS) using genotype information on a large number of genetic markers for large number of individuals. Due to varied study designs and genotyping platforms between multiple sites/projects as well as potential genotyping errors, it is important to ensure high quality data. Scripts an...

This paper presents an experimental approach to the problem of designing and executing walking gaits on a dedicated 2-legged machine. We have oriented all our approach towards the experimental analysis of large pattern of walking gaits. This work has lead to the first experimental results obtained on the Bip anthropomorphic robot. The desired movements are designed off line using a model of the...

Peer-to-peer (P2P) security has received a lot of attention as of late. Most prior work focused almost entirely on issues related to secure communication, such as key management and peer authentication. However, an important pre-requisite for secure communication – secure peer admission – has been neither recognized nor adequately addressed. Only very recently, some initial work began to make i...

This paper describes a likelihood based fine scale linkage disequilibrium mapping method for estimating the position of a disease predisposing gene relative to a battery of typed marker loci. The method uses multilocus allele frequency data from a sample of unrelated diseased individuals and from a sample of unrelated control individuals, that is, a case and control type design. This type of da...

We aimed to illustrate the importance of control-group selection on the results of risk factor analysis for (1) imipenem-resistant Pseudomonas aeruginosa, (2) vancomycin-resistant enterococci (VRE), and (3) ampicillin-sulbactam-resistant Escherichia coli. Case patients were compared with 2 different control groups: patients with the susceptible form of the organism (type 1), and control patient...

The authors' jobs in Shell involve responsibility for the analytical activity which includes about 220 people at the central research laboratory and roughly another 50 or so in quality control laboratories at various plants and refineries. Because it is a rapidly evolving technology, the chemists' arsenal of analytical methods continues to change (figure 2). Figure 2 represents the authors' exp...

This appendix draws heavily on the literature of warning and surprise and of military and technological innovation to assess Army intelligence’s tools for supporting the Army Strategic Planning System. Warning, surprise, and innovation are good analogues to use to evaluate Army intelligence assets for their appropriateness in support of the proposed decision-based planning system, for several r...

During the last several years, high-density genotyping SNP arrays have facilitated genome-wide association studies (GWAS) that successfully identified common genetic variants associated with a variety of phenotypes. However, each of the identified genetic variants only explains a very small fraction of the underlying genetic contribution to the studied phenotypic trait. Moreover, discordance ob...

Patient recruitment is a major challenge for randomised trials. Reviews of publicly funded UK trials have found that 45 to 69% fail to recruit to target. This increases costs, delays results, and adversely impacts on the feasibility of conducting trials for conditions where there is a limited patient pool. For some conditions a patient requires treatment on multiple occasions. For example, pati...
