This paper proposes a novel method to enhance performance of soccer robot system using optimal color patch mounted on the robot. In soccer robot system, the position and orientation of the robot can be estimated with color patch under real time environment. However, the location estimation of the robot is very sensitive to the pattern of color patch. In addition, pattern recognition and navigation algorithm are operated independently to reduce the operation time. The experimental results show that the proposed pattern of patch is effective to reduce the position and orientation error of the robot.

This study was done to investigate the use of nutritional supplements (NS) in Korean elite soccer players using an anonymous questionnaire. NS were classified into health supplements, manufactured health food supplements, chinese medicines & tonic foods, and nutrient supplements. Information was sought on the type of NS and factors that might influence supplement use including selected demographic parameters and health related variables. The data were collected from 241 athletes (aged $24.6{\pm}3.8$ years) in 9 professional soccer club. The prevalence of NS use among the subjects was 81.3%. Health supplements were used most frequently and nutrient supplement drug was the second one. Among the health supplements, weight/muscle gainer and calorie replacement product were most frequently used. Vitamin supplements were most frequently used among all nutrient supplement drugs. Users of NS were higher age (p<0.05) duration of exercise (p<0.05), and income (p<0.05) than non-users. The married (p<0.05) and a member of K-league (p<0.01) tended to have higher prevalence of NS use. The main adviser of NS were family (55.3%) and oneself (39%) instead of coach or sports nutritionist. Although NS use, only 26.2% certainly check up nutritional information on their used NS. Among the subjects, 84.5% of them felt that NS use were improved athletic performance, and 86.5% of them will to keep on taking supplement. These data suggest that a large number of elite soccer players use NS and these players may require education about healthy nutritional supplement practice and on the proper use of nutritional supplements.

This study was performed to compare nutritional supplementation habits for Korean professional soccer players with those for the non-athletic male adults. Information about prevalence and kinds of supplements taken, information sources, nutrition knowledge were collected. Data were obtained from 53 football players working for Korean professional football clubs and 44 non-athletic males, who answered a list of questionnaires which had been prepared in advance. The prevalence of supplement use in the soccer player group (96%) was strikingly higher than in the nonathletic male group (34%). Vitamins were taken most frequently, followed by red ginseng, multivitamin, Chinese medicine and amino acids supplements in the soccer player group, with each player taking 2.96 kinds of supplements in average. Multivitamin was the most popular supplement in the non-athletic male group. The major reason for taking supplements was not to feel and recover from fatigue in both groups. It appeared that the non-athletic males started to use supplements mostly by recommendation of friends or colleagues. Meanwhile, soccer players took supplements on their needs, with half of them (50.1%) provided with nutrition information. The most important information source was coaches for soccer players group, and mass media for the non-athletic male group. The average scores of soccer players group on basic nutrition and athletic nutrition were lower than the respective values of the non-athletic males. Among the soccer players, 68% had taken more than 3 kinds of supplements during the last year; nonetheless, more than half could not perceive the effectiveness of the supplements. Our results show that supplementation practices were widespread in soccer players, and suggest that nutrition education for proper use of supplements and overall health care is needed for soccer players.

This study was performed to compare food consumption patterns, dietary behavior, and nutrition knowledge between Korean professional soccer players and the non-athletic males. Data were collected from 53 soccer players working for Korean professional soccer clubs and 44 non-athletic males, using self-administered questionnaires. There were significant differences in food consumption frequency between two groups. Meats and eggs, fishes and shellfishes, sea weeds were consumed more frequently by the soccer players. The frequency scores of foods rich in iron, calcium, and protein were also higher in the soccer players compared with the non-athletes. Meanwhile, the consumption of alcohol was more frequent in the non-athletes. As for the cooking method, the soccer players showed higher preference for steaming/parboiling and consumed raw vegetables and fruits more frequently than the non-athletic males (p < 0.05). The average scores of soccer players on nutrition knowledge for basic nutrition and athletic nutrition were lower than the respective values of the non-athletic males. However, the soccer players showed better eating behaviors and dietary habits compared with non-athletic males (p < 0.001). They had well-balanced, regular diet and good habits for chronic disease prevention. No significant relationship could be observed with respect to nutrition knowledge and nutritional behavior. Moreover, the experience of getting nutrition information did not affect either nutrition knowledge score or nutritional habits score, except that for habits of chronic disease prevention in non-athletes. Therefore, it is suggested that more effective and practical nutrition education program be needed for promoting healthy eating habits and improving nutritional status in young males.
