The purpose of this review study is to examine current status of dietary supplement use to enhance athletic performance capacity in elite athletes based upon anti-doping education, sports type, athletic performance capacity, gender, and age. Several previous review studies have focused on the biochemistry characteristics and intake incidence of dietary supplements and those studies have not showed enough evidence of the reason why elite athletes usually take dietary supplements. Anti-doping education may increase the incidence of dietary supplement use in elite athletes because of increasing expertise of dietary supplements. It would be expected that increased incidence of long-term dietary supplement use may induce positive effects on the body having potential effects on athletic performance capacity, although a trace of nutrients may not directly effect on the outcome of the game. Moreover, it seems that the difference of dietary supplement use based upon gender and age may come from sports type and the difference of dietary supplement intake reason may come from health and body condition maintenance rather than athletic performance capacity when considering dietary supplement use items based upon intake reasons. Most elite athletes consume at least over 2 dietary supplement items in a long period of time rather than 1 dietary supplement item in a short period of time; however, the scientific evidence of dietary supplement use seems to be insufficient. Therefore, further experimental approach studies concerning dietary supplement effects would be needed.

운동선수를 평가하는 기준은 다양하지만, 그 가운데에서도 선수가 가진 신체 혹은, 공격과 수비에 대한 균형능력은 어느 종목에서나 공통적인 기준이 된다. 정보보호 분야에서도 이 균형을 얘기하는 사람들이 많이 있다. 규제와 자율, 보안성과 가용성. 이 모든 것을 적절히 활용하는 능력은 균형감각 없이는 어렵기 때문이다. 자유분방하기로 소문난 웹 서비스 업체의 구성원들 사이에서 기업의 보안을 책임져야 하는 네오위즈 게임즈 보안팀도 그런 균형감각에서 뛰어난 모습을 보여준다.

본 연구의 목적은 우리나라 17개 지자체별 문화시설 중 공공 체육시설 현황을 설치유형별, 종목별 간이운동시설로 구분 정리하여 지자체별 공공 체육시설의 분포도를 살펴보고, 이를 각 지자체별 인구수를 반영한 상대적인 비교 분석을 통해 지역별 적정한 공공 체육시설의 수를 알아보고자 한다. 분석 결과, 공공 체육시설들은 지자체별 인구수와 상이하게 분포되어 있다는 점을 확인하였다. 이러한 결과를 통해 인구수에 적합한 추가적 공공 체육시설 설치의 방향을 탐색할 수 있다.

The purposes of this study were to investigate the effects of strength training on the change of ground reaction force for the children with trisomy 21 Down syndrome. The subjects of this study were consisted of eight elementary school students with Down syndrome who participated in the strength training. The strength training was administered by six items such as squat, leg curl, leg extension, toe raise, sit-ups, and hyperextension. For strengthening muscle, each group also was treated by walking for 8 weeks, three times a week, 10-15RM, 3sets, which was based on the principle of progressive overload. For inquiring the effect of strength training, the ground reaction force variables were measured in two phases : before-training and 8 week-after training. The gait of each subject was acquisition using 2 AMTI force platforms set at 100 frequency. The results of this study were as follows: The pattern of vertical, antero-posterior and medio-lateral forces, trajectory of net COP and the timing ratio of reaching the each events were shown variously. So, it is not easy to explain these variables clearly. As the result of strength training, these variables were changed. However, the results of within subjects differ greatly, there was no difference statistically.

The study of Security Martial Arts is classified into nine categories; philosophy, history, education, sociology, psychology, physiology, training science, movement dynamics, and guard practice. The study of the theory and practice of Security Martial Arts should be concerned at first, for the development and progress for the future of Martial Arts. First, theoretical research that can be utilized in the real field should be performed, and such research outcomes are needed to be published as teaching materials and to be shared through various channels. Second, collaborative research of the characteristics of martial arts should be carried out. The Security Martial Arts would achieve a further development if training methods are complemented, and strengths and weaknesses of the events are fully understood. Third, studies for the independence of disciplines should be performed. The study field is derived into nine areas, and each is needed to be developed scientifically and systematically. Accompanied by sustainable study, academic autonomy of Security Martial Arts will be achieved.

This study intended to develop the Performance Evaluation system for the modern pentathlon such as an Olympic sporting event. The performance evaluation index system for the modern pentathlon was developed by Microsoft Excel 2016 with Visual Basic for Application that it is able to be understandable for the practical field in sport. Consequently, the system for the performance evaluation index is able to be developed within the concept of performance analysis of sport such as a notational analysis of sport. And the performance indicators for the performance evaluation index were selected by the skills to make successful outcomes. Finally, the simulation with big data gathering by the developed system would be requested that systematic reviews on successful outcomes in other sporting events would be necessary.

The Korea Sport Talent Search System (KOSTASS) can easily assess potential of Korean youth in 23 sport events and to identify sports talents who have high potential in track-and-field, swimming and gymnastics. The purpose of present study was to analysis relationship between sports talent test scores and KOSTASS scores. Physique, physical fitness, motor ability and physiological tests including skeletal age were administrated. Data of 201 elementary students who aged 7 to 12 living in Seoul area were collected. For pure association analysis, Pearson correlation coefficient and partial correlation coefficient are used and stepwise regression analysis is used for selecting important sports talent test scores. The results show that skeletal age, weight, chest circumference, 50-meter run, and half-squat jump have relatively low impact on six KOSTASS scores. The KOSTASS program would contribute to identify talented youth in sports among Korean youth population and success for international sports competition.

The Purpose of this study was to seek determinant factors through analysis of 65 snatch skill kinematic factors of Athletics participated in 2001 Asian weightlifting competetion. The conclusion were as follows ; 1. In order to enhance snatch skill, when barbell move on knee position, One should be flex knee joint to 105-110 degree, and In pull motion, One should be move powerful extension of knee and hip joint. 2. In last pull motion, One try to make more lock out motion than extra extention motion of hip joint 3. In order to enhance snatch skill, It is inportant that elevate barbell highly by last pull motion through powerful knee extention, poweful hip flextion and One should be make lock out motion fast in the same time. 4. In order to enhance snatch skill, anterior-posterior movement width of shoulder joint should be small. 5. In order to enhance snatch skill, Hip joint should be move vertically on start and lock out phase, but In pull phase, extension motion of hip joint shoulde be performed more largely and powerfully.

The purpose of this study was to develop a software system for computer nutrition counseling based on food intake and level of exercise measurements. Various software programs were developed using Powerbuilder 5.0 and categorized according to their function: 1) inputting general data including age, sex, weight, height, degree of acitivity and exercise amount of individuals, 2) inputting food intake based upon a 24-hour dietary recall method, 3) calculating energy and general nutrient intake and evaluating dietary status with respect to the Korean recommended dietary allowances, 4) calculating dietary intake of fatty acids, 5) calculating PUFA : MUFA : SFA and $\omega$6 :$\omega$3 ratios, 6) reporting the results of nutrient analysis, and 7) assessing the nutritional status of individuals and practicing nutrition education. This study provides various information on the assessment of nutritional status.

In this paper, an interface for the physical interactive game based on the exercise movement was designed. The interface which uses exercise motion detects was designed and applied to the physical interactive game. As a result, this application to the contents was made possible by combining the physical movements that involve motility through the training method. Furthermore, accurate exercise motions that correspond to each situation were induced using the game objects. The developed interface is expected to be used in a physical interactive game that incorporates other types of exercises.
