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.

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.

It is widely known that the home advantage plays an important factor for determining victory or defeat in sport leagues. Thus a ranking system of sport league should take account of the home advantage as a key factor. Various statistical models are studied to rate the Korean Basketball league teams in 2006-2007 season. Among them, the model equation provided by Harville and Smith (1994) is useful for constructing two ranking systems. Both systems give quite reasonable quantifications of the team's ability and the home advantage.

The phenomena and game records that occur in sports matches are being analyzed in the field of sports game analysis, utilizing advanced technologies and various scientific analysis methods. Among these methods, social network analysis is actively employed in analyzing pass networks. As football is a representative sport in which the game unfolds through player interactions, efforts are being made to provide new insights into the game using social network analysis, which were previously unattainable. Consequently, this study aims to analyze the changes in pass networks over time for a specific football team and compare them in different scenarios, including variations in the game's nature (Qatar World Cup games vs. A match games) and alterations in the opposing team (higher FIFA rankers vs. lower FIFA rankers). To elaborate, we selected ten matches from the games of the Korean national football team following Coach Bento's appointment, extracted network indicators for these matches, and applied four indicators (efficiency, cohesion, vulnerability, and activity/leadership) from a football team's performance evaluation model to the extracted data for analysis under different circumstances. The research findings revealed a significant increase in cohesion and a substantial decrease in vulnerability during the analysis of game performance over time. In the comparative analysis based on changes in the game's nature, Qatar World Cup matches exhibited superior performance across all aspects of the evaluation model compared to A matches. Lastly, in the comparative analysis considering the variations in the opposing team, matches against lower FIFA rankers displayed superior performance in all aspects of the evaluation model in comparison to matches against top FIFA rankers. We hope that the outcomes of this study can serve as essential foundational data for the selection of football team coaches and the development of game strategies, thereby contributing to the enhancement of the team's performance.

본 연구는 우리나라를 대상으로 장단기 스프레드와 신용스프레드가 경기변동에 대해 어떠한 예측력을 갖고 있는가를 살펴보았다. 이를 위해 1991년부터 2001년까지를 분석기간으로 하여 Probit 분석을 통해 금리스프레드와 경기변동과의 시차 및 불황확률을 추정하여 평가해 보았으며, 인과관계 검정을 시도해 보았다. 우선 금리스프레드와 경기변동에 대한 불황확률을 알아보기 위해서 Probit 모형을 이용하여 불황확률을 추정하였다. 그 결과 장단기 금리스프레드 중에서는 5년 만기 1종 국민주택채권수익률-콜금리(HCS)는 3개월, 5년 만기 1종 국민주택채권수익률-1년 만기 금융채수익률(HGS)은 7개월, 5년 만기 1종 국민주택채권수익률-1년 만기 통안증권수익률(HMS)은 9개월의 시차를 보이는 경우가 Pseudo $R^2$ 값이 가장 높게 나타났지만 불황확률을 토대로 경기 호황과 불황 국면을 비교해 본 결과 HMS는 Pseudo $R^2$의 값도 상대적으로 높았을 뿐만 아니라 매우 높은 경기변동 예측력을 보여주었다. HCS와 HGS의 경우에는 IMF 체제 전후의 불황기와 그 이후에 도래한 호황기는 예측력이 높게 나타났으나 1990년대 초반에는 제대로 불황확률을 예측하지 못하는 것으로 나타났다. 또한 3년 만기 회사채수익률-5년 만기 국민주택채권수익률(CHS)와 3년 만기회사채수익률 -3년 만기 금융채수익률(CGS)로 나타낸 신용 스프레드에서는 유의적인 결과를 도출하지는 못하였다. 한편 인과관계에서도 HCS, HGS, HMS 등의 장단기 스프레드는 경기변동에 대하여 일방적 원인변수로 작용하는 것으로 나타나 선행결합관계를 보여주었으나 CHS, CGS 등의 신용스프레드는 경기변동과 어떠한 유의적인 결합관계도 보여주지 못하였다. 따라서 장단기 스프레드는 경기변동을 예측하는데 유용한 정보를 제공하지만 신용스프레드는 경기변동을 예측하는데 도움을 주지 못하는 것으로 나타났다.

Archer's capability of attention and relaxation control during shooting process was evaluated using EEG technology. Attention and meditation algorithms were used to represent the levels of mental concentration and relaxation levels. Elite, mid-level, and novice archers were tested for short and long distance shootings in the archery field. Single channel EEG was recorded on the forehead (Fp1) during the shooting process, and attention and meditation levels were computed by real time. Four types of variations were defined based on the increasing and decreasing patterns of attention and meditation levels during shooting process. Elite archers showed increases in both attention and relaxation while mid-level archers showed increased attention but decreased relaxation. Elite archers also showed higher levels of attention at the release than mid-level and novice archers. Levels of attention and relaxation and their variation patterns were useful to categorize archers and to provide feedback in training.

This study tried to analyze the types of sport emotion by sport game characteristics. For that, 7 soccer games and 6 baseball games of Korean team in 2018 Asian Games were selected, and the articles and their replies about those on social network services were collected as study materials. Python was used for the collecting and expert group meeting was held for the emotion analysis. As the results of the analysis on sport emotion types by win or lose, the level of opponents and the performance of Korean team as game characteristics, the following conclusions were drawn. First, it was hard to say that win or lose and opponent's level make certain sport emotion type. Second, The performance could made contended, enthusiastic and joyful emotions when judged good, but frustrated, angry, humiliated emotions when bad. Third, social·cultural background or certain event of the games also could effect on the sport emotion types. Follow-up studies with the other game characteristics and more game cases were needed to find out more clear causal relationship.

Recently, intensive research efforts are world-widely forced on the development of sport shoes improving both the injury protection and the playing performance by taking kinesiology and biomechanics into consideration. However, the success of this goal depends definitely on the reliable evaluation of the dynamic responses of sport shoes and human foot, particularly the landing impact characteristics. It is because the landing impact force is a main source of unexpected injuries and influences the playing performance in court sport activities. This paper addresses the application of finite element method to the evaluation of landing impact characteristics of barefoot and several representative court sport shoes in running. In order to accurately reflect the coupling effect between human foot and shoes accurately, we construct a fully coupled three-diemensional foot-shoe FEM model which does not rely on the independent experimental data any more. Through the numerical simulation, we assessed the reliability of the numerical FEM model by comparing with the experimental results and investigated the landing impact characteristics, such as GRF, MIF, acceleration and frequency responses, of representative court sport shoes.

The team's performances were analyzed by evaluating the scores gained by their offense and the scores allowed by their defense. To evaluate the team's attacking and defending abilities, we also considered the factors that contributed the team's gained points or the opposing team's gained points? In order to analyze the outcome of the games, three prediction models were used such as decision trees, logistic regression, and discriminant analysis. As a result, the factors associated with the defense showed a decisive influence in determining the game results. We analyzed the offense and defense by using the response variable. This showed that the major factors predicting the offense were non-stop pass and attack speed and the major factor predicting the defense were the distance between right and left players and the distance between front line attackers and rearmost defenders during the game.
