운동자들의 운동 정보를 측정하기 위하여 스마트 폰의 운동 애플리케이션들은 GPS장치에서 얻은 정보들을 사용한다. 이러한 애플리케이션에서 사용자에게 제공하는 운동정보는 뛰거나 걸은 거리, 시간, 칼로리 소모량, 평균 속도 등 이다. 이들 중 운동한 거리는 모든 정보의 바탕이 되므로 정확한 측정이 필요하다. 그러나 현재 사용되는 거리 측정법은 지구를 구 또는 타원으로 가정하여 계산하기 때문에 실제 운동거리와는 오차가 생기게 된다. 실제로 지구의 표면은 경사로 이루어져 있기 때문이다. 본 논문에서는 이 오차를 보정하여 지형의 경사도를 반영한 새로운 거리측정 알고리즘을 제안한다. 제한된 알고리즘의 성능을 평가하기 위하여 스마트 폰을 기반으로 한 운동 라이프가이드 시스템을 구축하였다. 실험을 통하여 제안된 알고리즘이 보다 정확한 운동 거리 측정 정보를 제공함을 보인다.

The purpose of this study is to discovered assessment items for improving athletic efficiency and management of golf courses. Through this, the study intended to provide basic data for creating competitive golf courses and management. Important assessment items were selected by inducing preliminary assessment items and conducting a preliminary survey and a main survey for specialists through a theoretical study. For the survey results studied, reliability and average value for importance were calculated using SPSS/PC Window Release 12.0. As assessment of importance by assessment area, in athletic efficiency assessment, course management level was the highest, followed by fairness of games and operation of games. In management assessment, importance of service level, information management, facility management, management of game assistants, etc. were high. As assessment of importance by assessment item, it was found that 'variety of golf shot' and 'the length of a course' were important in course layout. Also 'start interval among teams' and 'disturbance of play' were assessed as important items in game operation, while 'fair reservation' and 'rounding rotation time' were important in fairness of games. In addition, in information management, 'kind service of golf course staffs' and 'prompt reservation and notification' were found to be important assessment items. In facility management, all assessment indexes were over 4.0, which means all of them are important for quality of golf course and competitiveness. In membership service, 'appropriate price of goods for sale' and 'service for members' were relatively important assessment items. Further, in management of game assistants, 'qualifications and skillfulness of game assistants' was assessed as a very important index. Although the current study only selected important items to assess excellent golf courses, it is necessary to apply the study results to the actual sites and verify them for golf course both at domestic and abroad.

본 연구는 퍼스널트레이너-고객 간의 라포형성이 운동성과에 미치는 영향관계를 커뮤니케이션 스타일을 중심으로 인과 관계(SEM)를 밝히고자 하였다. 이에 2022년 10월 1일부터 4월 28일까지 표본계획에 의해 PT고객 187명을 대상으로 모바일 프로그램 '서베이몽키'를 통해 다음과 같은 결과를 도출 하였다. 첫째, 커뮤니케이션 스타일은 라포형성에 영향(+)을 미치는 것으로 나타났다. 둘째, 커뮤니케이션 스타일은 운동성과에 부분적으로 영향(+)을 미치며, 통제형은 영향관계가 성립되지 않았다. 셋째, 라포형성이 운동성과에 영향을 미치는 것으로 나타났다. 따라서 PT는 일반적인 서비스가 아닌 인적 서비스이기에 그 중요성이 더욱히 강조되어야 될 것이다. 또한, 치열한 PT시장에서 우위를 점하는 것은 바로 고객이 반응할 수 있는 표현방식 언어적 측면과 비언어적 측면을 적절하게 반영된다면 운동성과와 경영성과 둘 동시 영향을 줄 것으로 판단된다.

Objective: Since athletic performance is a most importance trait in horses, most research focused on physiological and physical studies of horse athletic abilities. In contrast, the molecular analysis as well as the regulatory pathway studies remain insufficient for evaluation and prediction of horse athletic abilities. In our previous study, we identified AXL receptor tyrosine kinase (AXL) gene which was expressed as alternative spliced isoforms in skeletal muscle during exercise. In the present study, we validated two AXL alternative splicing transcripts (named as AXLa for long form and AXLb for short form) in equine skeletal muscle to gain insight(s) into the role of each alternative transcript during exercise. Methods: We validated two isoforms of AXL transcripts in horse tissues by reverse transcriptase polymerase chain reaction (RT-PCR), and then cloned the transcripts to confirm the alternative locus and its sequences. Additionally, we examined the expression patterns of AXLa and AXLb transcripts in horse tissues by quantitative RT-PCR (qRT-PCR). Results: Both of AXLa and AXLb transcripts were expressed in horse skeletal muscle and the expression levels were significantly increased after exercise. The sequencing analysis showed that there was an alternative splicing event at exon 11 between AXLa and AXLb transcripts. 3-dimentional (3D) prediction of the alternative protein structures revealed that the structural distance of the connective region between fibronectin type 3 (FN3) and immunoglobin (Ig) domain was different between two alternative isoforms. Conclusion: It is assumed that the expression patterns of AXLa and AXLb transcripts would be involved in regulation of exercise-induced stress in horse muscle possibly through an $NF-{\kappa}B$ signaling pathway. Further study is necessary to uncover biological function(s) and significance of the alternative splicing isoforms in race horse skeletal muscle.

Objectives: Accurate assessment of energy expenditure is important for estimation of energy requirements in athletic children. The objective of this study was to evaluate the accuracy of accelerometer for prediction of selected activities' energy expenditure and intensity in athletic elementary school children. Methods: The present study involved 31 soccer players (16 males and 15 females) from an elementary school (9-12 years). During the measurements, children performed eight selected activities while simultaneously wearing the accelerometer and carrying the portable indirect calorimeter. Five equations (Freedson/Trost, Treuth, Pate, Puyau, Mattocks) were assessed for the prediction of energy expenditure from accelerometer counts, while Evenson equation was added for prediction of activity intensity, making six equations in total. The accuracy of accelerometer for energy prediction was assessed by comparing measured and predicted values, using the paired t-test. The intensity classification accuracy was evaluated with kappa statistics and ROC-Curve. Results: For activities of lying down, television viewing and reading, Freedson/Trost, Treuth were accurate in predicting energy expenditure. Regarding Pate, it was accurate for vacuuming and slow treadmill walking energy prediction. Mattocks was accurate in treadmill running activities. Concerning activity intensity classification accuracy, Pate (kappa=0.72) had the best performance across the four intensities (sedentary, light, moderate, vigorous). In case of the sedentary activities, all equations had a good prediction accuracy, while with light activities and Vigorous activities, Pate had an excellent accuracy (ROC-AUC=0.91, 0.94). For Moderate activities, all equations showed a poor performance. Conclusions: In conclusion, none of the assessed equations was accurate in predicting energy expenditure across all assessed activities in athletic children. For activity intensity classification, Pate had the best prediction accuracy.
