This study has been conducted to design and implement smart phone-based application which can keep records effectively to improve athletes' ability. To boost their performance, they need to receive training as realistic as possible. As a way to do that, training should be performed with some fitness equipments, sporting apparatus, facilities, and conditions. However, it is also possible to improve their ability by motivating athletes with checking and recording their performance. This study ascertains that using scoring records actually motivates athletes when comparing the result of youth basketball team using the records keeping system with that of not using it. Accordingly, smart phone-based records keeping application has been designed and developed. Also, through a survey targeting athletic coaches who have used the system, training efficiency has been measured and it turns out that it actually motivates athletes to improve their abilities.

The importance of record management is emphasized in various fields. In the field of sports in particular, the importance of record management is key, and many efforts are being made to keep a record of the history of many sports. Therefore, in this study, a plan to develop a sports record information service centered on basketball was proposed. In this study, the sports records information service development plan that is described not only has an eye toward developing technology, but is also described from the perspective of records management, which has recently been in high demand. To this end, a demand analysis was conducted on prospective users through FGI, and procedural elements of record analysis were derived. In addition, the system structure and database schema were designed, and a screen for managing and browsing records was presented. Through this study, it is expected that research on sports record management will be able to be actively conducted in the record management field.

In this study, it was evaluated that the 3D tracking accuracy of basketball zone track line by real time GNSS satellite positioning methods which are VRS (Virtual Reference System), DGPS (Marine Differential GPS) and PP (Point Positioning) methods. The results of comparison between three methods over horizontal track of basketball zone, VRS, DGPS and PP methods showed ${\pm}$ several cm, ${\pm}$ m, and ${\pm}$ 2m horizontal position accuracy compared with real size respectively. And also, the grade and height deviation of the checking points on basketball zone by VRS method is very similar to the real grade and height, but results by DGPS and PP methods showed big variation and deviation in each case. We expected that VRS method using GNSS reference network will be a very useful tool compared with single based RTK method in real time accurate positioning such as precision construction fields, especially.

스포츠 통계와 관련된 주제들은 경기결과의 설명 예측력 분석, 선수와 팀 평가, 경기내용의 요약, 경기의 환경적 요인 평가, 경기 규칙 분석, 경기결과의 시각적 표현, 토너먼트 구조 연구 등의 영역으로 다양하다. 이 글에서는 야구 축구 농구 테니스 종목을 중심으로 통계적 방법을 적용하여 스포츠 현장의 문제를 어떻게 접근하고 있는지를 개괄하였다. 전통적으로 스포츠 통계는 선수와 팀 그리고 전략의 평가가 주를 이루었지만, 오늘날 스포츠통계는 경기의 잠재적, 외적 요인 등의 주제로 관심영역을 넓혀가고 있다. 그러나 국내에서는 경기내용의 기술적(descriptive) 분석이 주류를 이루고 있으며, 전문적 수준의 통계적 접근은 활발하지 못하고 있다. 현장과 자료의 특성을 고려하여 통계와 스포츠(체육)분야의 다양한 협동연구가 필요하다.

Isolated stress fracture of the first rib is rare, and repeated muscular pulling and fatigue of bone is thought to be responsible for this fracture. The diagnosis can be made by taking a thorough history and performing chest roentgenography, computed tomography or magnetic resonance imaging. Conservative treatment generally cures this condition. We report here on a case of exercise-induced isolated stress fracture of the first rib in a non-athlete college student and we review the related articles.

The purpose of this study were to investigate the effects of knee brace on the knee muscular neuro-biomechanical variables during the rebound in female highschool basketball players. Twelve high school female ($17.9{\pm}0.8years$) basketball players rebound jumped for maximal vertical height to sufficiently stress the anterior cruciate ligament with and without knee brace. Kinematic data were collected to estimate the knee flexion, abduction angles and jump height. The EMG data from the biceps femoris and rectus femoris was used to estimate the ratio of quadriceps muscle activity. Female athletes with knee brace showed more reduced the knee abduction angle and the ratio of quadriceps muscle activity at foot contact phase than without knee brace. In conclusion, Female athletes with brace reduced knee anterior cruciate ligament loads.

Stress fractures of the proximal phalanx of the great toe are rare. This fractures have been associated with halux valgus deformity in most reports. We performed open reduction and internal fixation with distal chevron osteotomy for the stress fracture of the proximal phalanx of the great toe in a basketball player with hallux valgus, and obtained successful bony union and rapid return to sports.

The aim of this study was to examine characteristics between nutrient intakes, body composition and physical fitness in gifted athletic boys. The subjects were conducted in 50 boys aged 9~12 years living in Busan, Ulsan and Gyeongsangnam-do, Korea. Dietary intake information was collected from participants using 3-day food recorded and body composition was measured by bioelectrical impedance analysis, and their anthropometric parameters were measured. Swimming group's daily energy intakes were significantly higher compared to those of other groups. Athletics and swimming groups were significantly taller than gymnastics. Swimming group was significantly higher than gymnastics group in weight, fat mass, body fat percent and lean body mass. Athletics and swimming groups were significantly longer than gymnastics group in sit and ball throwing. Swimming group was significantly better than other groups in sit up, and athletics group was significantly faster than gymnastics group in 50 m run. In correlation result for nutrient intake and body composition: 1) Body weight shows positive correlation with protein, phosphorus, sodium, vitamin $B_1$, C and niacin. BMI shows positive correlation with sodium and niacin. Fat mass shows positive correlation with niacin and folate. Body fat% shows positive correlation with vitamin C, E, niacin and folate. LBM shows positive correlation with all elements except lipid, calcium, vitamin A, C, E and folate. In correlation result for nutrient intake and physical fitness: 2) Push up shows positive correlation with iron and vitamin C. Sit and throw ball shows positive correlation with the events except lipid, fiber, vitamin A, E and folate. Sit up shows positive correlation with vitamin $B_1$. Half squat shows positive correlation with iron. Standing long jump shows positive correlation with total energy, lipid, and vitamin A, B and $B_2$. Long run shows negative correlation with protein, carbohydrate, fiber, phosphorus, iron, sodium and zinc. Side step shows positive correlation with niacin. Sit and reach shows negative correlation with total energy, carbohydrate, phosphorus, sodium, zinc and vitamin $B_2$. In correlation result for body composition and physical fitness: 3) Sit and throw ball shows positive correlation with body weight, BMI, fat mass, body fat% and LBM. Standing long jump shows positive correlation with LBM. But long run and 50 m run shows negative correlation with body weight and LBM.
