There are three different well-known methods for predicting the manoeuvrability of ships: (1) free running model test, (2) direct manoeuvring simulation using CFD and (3) system-based manoeuvring simulation. In this paper, the manoeuvrability of the KVLCC2 was estimated using CFD with rigid body motion and body force propeller method. The free running manoeuvre at the different time steps were also simulated. The yaw checking ability and the turning ability of KVLCC2 were predicted using CFD and could have been confirmed that the IMO criteria was satisfied. When the results were compared with the model test and system-based method, the free running simulation showed better agreement to that of the model test. It could also be confirmed that the results vary depending on the time step. Overall, the CFD results using the body force propeller method estimated most accurately the test results.

Aims: Nonalcoholic fatty liver disease (NAFLD), a hepatic manifestationof the metabolic syndrome, was associated with subclinical atherosclerosis atherosclerosisin many crosssectional studies, but the prospective associationbetween NAFLD and the progression of atherosclerosis has not beenevaluated. This study was conducted to evaluate the association betweenNAFLD and the progression of coronary atherosclerosis.Methods: This cohort study included 4,731 adult men and womenwith no history of CVD, liver disease or cancer at baseline who participatedin a repeated regular health screening exam between 2004and 2013. Fatty liver was diagnosed by ultrasound based on standardcriteria, including parenchymal brightness, liver-to-kidney contrast,deep beam attenuation and bright vessel walls. Progression of coronaryartery calcium (CAC) scores was measured using multidetectorCT scanners.Results: The annual rate of CAC progression in participants with andwithout NAFLD were 22% (95% confidence interval 20 - 23%) and17% (16 - 18%), respectively (p<0.001). The multivariable ratio ofprogression rates comparing participants with NAFLD to those withoutNAFLD was 1.04 (1.02 - 1.05; p<0.001). The association betweenNAFLD and CAC progression was similar in most subgroups analyzed,including in participants with CAC 0 and in those with CAC > 0at baseline.Conclusions: In this large cohort study of adult men and womenwith no history of CVD, NAFLD was significantly associated with thedevelopment of CAC independently of cardiovascular and metabolicrisk factors. NAFLD may play a pathophysiologic role in atherosclerosisdevelopment and may be useful to identify subjects with a higherrisk of subclinical disease progression.
