• A necessity of following cyber security controls in order of priority for efficiency. • Investigation and classification of the cyber attack probability variables for NPPs. • Quantifying the relative importance of NPP cyber attack probability variables by using FA and AHP. • Identification of Korean cyber security controls that have higher priority to be implemented. The cyber security of NPPs recently has become a major issue, and a utility in Korea is requested to follow cyber security controls and to perform cyber security risk management based on the regulatory guide RS-015. Since it is difficult to fully implement the controls with limited resources, it is necessary to find which controls are relatively more important than other controls. The aim of this study is to develop a method for quantifying the relative importance of NPP cyber attack probability variables. These variables were investigated, and rearrangement and classification of them was validated by the factor analysis method. The relative importance among the variables was quantified by the AHP method. By applying the relative importance to the regulatory guide, the controls that have higher priority to be implemented were identified. Considering the relatively more important controls, it is expected that the utility can follow cyber security controls efficiently. [ABSTRACT FROM AUTHOR]

Abstract: Despite growing concerns about the co-morbidity of metabolic syndrome (MetS) and bipolar disorder, few studies have been conducted on this topic in Asian populations. This study examined Korean patients with bipolar disorder to assess its co-morbidity with MetS and to compare the prevalence of MetS in patients with medication for bipolar disorder with that of healthy patients. We used cross-sectional data from the medical records of patients with bipolar disorder who presented to the psychiatric clinic in Seoul National University Hospital between June 2007 and June 2008. The control group, matched for age and gender, was randomly drawn from visitors to the Health Promotion Center at the same hospital during the same period. We compared the prevalence of MetS between these two groups with independent sample t-tests and chi-squared tests. We also calculated the indirectly standardized prevalence ratio (ISPR) with a standardization that used the Fourth Korean National Health and Nutrition Examination Survey (KNHNES, 2007). The prevalence of MetS in patients who took medication for bipolar disorder (N=152) was 27.0%, 25.0% and 25.7%, based on the definitions of the American Heart Association and the National Heart, Lung and Blood Institute''s adaptation of the Adult Treatment Panel III (AHA), the National Cholesterol Education Program for Adult Treatment Panel III (ATPIII) and the International Diabetes Federation (IDF), respectively. The present study determined that the prevalence of MetS was significantly higher in patients with bipolar disorder than in the control group; the odds ratios (OR) (95% CI) were 2.44 (1.35–4.40), 2.48 (1.34–4.59) and 2.57 (1.40–4.74), based on the definition of the AHA, ATPIII and IDF, respectively. The ISPR (95% CI) was 1.48 (1.02–1.93), 1.54 (1.05–2.03) and 1.98 (1.36–2.60), respectively. Patients with medications for bipolar disorder showed a significantly higher prevalence of increased waist circumference, elevated triglycerides, and reduced HDL-cholesterol than the control group. The prevalence of MetS in patients taking medication for bipolar disorder was higher than that in the general population. Obesity and dyslipidemia were particularly prevalent in patients with bipolar disorder. [Copyright &y& Elsevier]
