Abstract

Background/Objectives: The currently operating system of city information is not working smoothly due to not only the utilizing problem of existing infra but also the irrationality of separated operation for each service, but also the lack of providing service that is integrated with various information. To address these problems, this paper proposes a City-logging system. Findings: This study suggests the system of City-logging that is providing a convergence service of city information for the purpose of solving the above mentioned problem. The suggested system is to provide the information such as a traffic census, a police control of illegal parking and stopping, and the monitoring of air pollution. Improvements/Applications: After analysis of collected data from the mobile monitoring equipment, as the service is provided, the security network for the purpose of improving accuracy and safety of information is built and data is encrypted to deal with privacy. The proposed system will be realized and the efficient operating method of city information service will be suggested after this.

Abstract

Background/Objectives: The Second Digit (2D) to Forth Digit (4D) ratio is widely used as an indirect biological indicator that represents the prenatal sex hormone environment. This study was conducted to identify the relationships between the 2D:4D ratio and sexual dimorphism, BMI, exercise capacity and handedness targeting Taekwondo athletes. Methods/Statistical Analysis: Data was collected using a self-report questionnaire and the scanning of both hands from July to October 2015, targeting a total of 224 Taekwondo athletes including 84 national team athletes (51 males and 33 females) and 140 collegiate athletes (100 males and 40 females). The self-report questionnaire was composed of items necessary for measurement of BMI and exercise capacity such as gender, age, height, weight, type of handedness, award-winning experience, etc. Findings: As a result, the 2D:4D ratio of left-handedness showed a statistically significant difference in sexual dimorphism and the 2D:4D ratio between left-handedness and right-handedness showed a statistically significant correlation for both males and females. However, there was not a statistically significant correlation between the 2D:4D ratio and BMI index in left-handedness and right-handedness for both males and females. Application/Improvements: The findings of this study are meaningful in that they can be used as basic data necessary to find and nurture talented students with excellent qualities for becoming a Taekwondo athlete.

Abstract

Background/Objectives: This study was conducted to identify the skinfold thickness and the characteristics of muscle mass of judo and Taekwondo athletes by comparing the data on those athletes with the data on non-martial art athletes engaged in sporting activities. Methods/Statistical Analysis: For the purpose, 20 collegiate athletes were selected from collegiate judo and Taekwondo athletes and handball, rugby, table tennis and badminton players of the same ages. So, a total of 120 collegiate athletes were selected as participants in this study. And we evaluated skinfold thickness and muscle mass components based on the anthropometry manual presented by International society for accreditation kinanthropometry. Findings: We showed that judo athletes had larger skinfold thickness and muscle mass than the mean compared with non-martial arts players; Taekwondo athletes, who are martial arts athletes similar to judo athletes, had very small skinfold thickness compared with non-martial arts players and a little larger muscle mass than racket sports players such as badminton and table tennis players. Application/Improvements: It is confirmed that the formula used by this study was appropriate for determining the ranking of muscle masses of athletes by sport types and available for their comparison with the muscle masse of a corpse.
