“…Data including lifestyle factors (eg, age, sex, physical activity, alcohol consumption, tobacco smoking, education level, diet, and marital status), body composition, and anthropometric measurements were obtained from the KoGES and the KCDC. 31 The alcohol consumption and smoking status of the study population were categorized as follows: never, past, and current. Education level was classified as follows: 'low' for individuals who graduated elementary school or less, 'medium' for middle Obesity studies school or high school graduates, and 'high' for those who obtained at least a college graduate degree.…”

IntroductionThe fat mass and obesity-associated (FTO) gene is a significant locus in obesity. However, the association betweenFTOgenetic variants and body composition has not been fully elucidated.Research design and methodsThis observational study examined the associations ofFTOrs9939609 T>A with obesity and body composition markers in Koreans. A total of 6474 participants from the Korean Genome and Epidemiology Study were analyzed for their general characteristics, body composition andFTOgenotype with a sex-stratified approach.ResultsFemales with the obesity risk A allele showed significantly greater body weight, hip circumference, and body mass index and were at a 1.28-fold higher risk of obesity (95% CI=1.088 to 1.507) than those with the TT genotype. Analyses of body composition also showed that females with the A allele had a greater body fat mass and percentage, abdominal fat percentage, and degree of obesity, and this association andFTOgenetic variation and adiposity was observed in females, especially aged under 50 years. However, the effect of the variant allele on non-fat tissue markers was not evident in females and was not associated with any parameters examined in males.ConclusionsTheFTOrs9939609 variant is associated with body composition in Koreans, especially body fat markers in females. These results support that theFTOrs9939609 variant is a genetic risk factor in the etiology of obesity.

The berthing velocity is the factor that has the greatest influence on the berthing energy. For the vessel to berth safely, it should not exceed the appropriate berthing velocity. In addition, when the vessel is berthing, it should be berthed with berthing energy smaller than the energy absorption of the fender. This study intends to derive the allowable berthing velocity by ship size considering the berthing capacity. When a small vessel berth, the allowable berthing velocity is greater than when a relatively large vessel berths. In this study, the extrapolated velocity is defined as the relative value of the ship’s berthing velocity when considering the ship's size and the berthing capacity. A regression equation for the allowable berthing velocity by ship size was derived by calculating the designed berthing energy for each fender performance. It was also verified whether any ships were exceeding the allowable berthing velocity by comparing it with the measured data for each jetty. In addition, the extrapolated velocity was proposed using the regression equation, and as a result of applying the measured data, 11 ships exceeded the designed velocity in jetty 1, but it was confirmed that all ships were safely berthed in jetty 2,3. Therefore, the target pier of this study was evaluated as a pier where ships can be berthed safely. A safer berthing velocity operation guideline can be suggested if the allowable berthing velocity by ship size is analyzed and utilized at various piers. Extrapolated velocity can also be used for risk analysis of berthing.
