Objective: The purpose of this study was to investigate the differences between visual search, eye fixation positions, and eye fixation position on whole body regions while judging final matches of dance sports. Method: Ten experienced judges (male 6, female 4) and six dance sports couples belonging to the top Korean leagues in the Korea Dance sports Federation were participated. Wearable eye trackers were used for data collection. The independent t-test was conducted to examine the effects of gender, and the two-way ANOVA was conducted to examine the effects of judges' gender, dance event, and ranking. Results: It was found that the movement of male contestants was preferred, and the gaze fixation was high for torso movements in the judges' evaluations. Moreover, attention was focused on the upper body rather than the lower body; this was maintained for about seven seconds to evaluate each couple. Conclusion: This find was the relative comparison between the two couples was the determining factor in winning or losing.

Bovine fecal microbiota is important for host health and its composition can be affected by various factors, such as diet, age, species, breed, regions, and environments. The objective of this study was to evaluate the impact of diet and gender on fecal microbiota in Korean native Hanwoo cattle. The 16S rRNA gene amplicon sequencing of fecal microbiota was conducted from 44 Hanwoo cattle divided into four groups: (1) 11 heifers fed an oat hay plus total mixed ration (TMR) diet for breeding (HOTB), (2) 11 heifers fed an early fattening TMR diet (HEFT), (3) 11 steers fed the early fattening TMR diet (SEFT), and (4) 11 steers fed the late fattening TMR diet (SLFT). Firmicutes and Bacteroidota were the first and second most dominant phyla in all the samples, respectively. The Firmicutes/Bacteroidota (F/B) ratio associated with feed efficiency was significantly greater in the SLFT group than in the other groups. At the genus level, Romboutsia, Paeniclostridium, and Turicibacter were the most abundant in the SLFT while Akkermansia, Bacteroides, and Monoglobus were the most abundant in the HOTB group. Although the same early fattening TMR diet was fed to Hanwoo heifers and steers, Marvinbryantia and Coprococcus were the most abundant in the HEFT group while Alistipes and Ruminococcus were the most abundant in the SEFT group. Shannon and Simpson diversity indices were significantly lower in the SLFT group than in the other groups. Distribution of fecal microbiota and functional genetic profiles were significantly different among the four treatment groups. The present study demonstrates that different diets and genders can affect fecal microbiota and the F/B ratio may be associated with feed efficiency in Hanwoo cattle. Our results may help develop strategies to improve gut health and productivity through manipulation of fecal microbiota using the appropriate diet considering Hanwoo cattle gender.

Successful completion of a visual task in a predetermined time is very crucial to many operations such as piloting an aircraft. Although existing ergonomic interface models often provide a function of vision tests, it determines only the visibility at any given location. To complement this problem in existing models, the isoresponse time region considering the factors related to visual tasks is presented. Using a multiple regression model, equal response time regions were obtained within which mean response time is expected to be the same and is asymmetrical in shape. Among the factors considered, expectancy significantly decreased response time, and when cued, the effects of field heterogeneity, target uncertainty, density, size contrast and peripheral position on search time were less significant than those in unexpected cases. Response time and error rate, gender and visual acuity were not significantly correlated, and response time and age was positively correlated. These results are expected to be directly applicable to designing various visual tasks in real-life situations.

Purpose: This study reports on limb amputations in diabetic patients according to gender, age, and region based on the data from the Korean Health Insurance Review & Assessment Service. Materials and Methods: The number of amputations was compared by region, age, gender, and year, as well as by femoral region, lower leg, foot, and toe in diabetic patients who received limb amputation. This analysis was performed based on the data from the Korean Health Insurance Review & Assessment Service, between January 2009 and December 2014. Results: The total number of amputations between the study period was 9,155. The number of patients who were treated at hospitals for diabetes in 2009 was 1.9 million, among which, 1,214 patients underwent amputation. In 2014, the incidence of diabetes was 1,747 in 2.58 million individuals. With this rising incidence of diabetes, the amputation of limbs due to diabetes is increasing every year. In particular, the following regions were amputated more often: femoral region, 2.3%; lower legs, 19.6%; feet, 18.1%; and toes 60.0%. Regarding gender differences, males showed a higher amputation rate than females for all body parts. With respect to region, Seoul was the highest with 30.2%, followed by Gyeonggi with 19.9%, and Busan with 8.8%. According to age, older age showed greater diabetic amputation rate. Conclusion: In accordance with the rising incidence of diabetes, the diabetic amputation is also increasing. Here, we showed that toes were amputated with the highest percentage and males had greater amputation rate than females for all body parts. Moreover, amputation rate was highest in older diabetic patients, especially for those in their seventies. Additionally, Seoul was the region with highest amputation rate.
