The purpose of this study was to analyze sports injuries which occurred in Korea National Team during official training period. All sports injuries are recorded on injury report form by physicians, medical staffs and athletic trainer, and only acute and recurred injuries were analyzed. Total 3,421 injuries were reported, and 1,560 injuries were newly incurred and 1,861 injuries were recurrent with previous history. The frequency of new injuries in male and female athletes was highest in boxing (n=130, 14.5%) and hockey (n=75, 11.3%) respectively. The frequency of recurred injuries in male and female athletes was highest in wrestling (n=147, 14.8%) and fencing (n=103, 11.9%) respectively. Our data provides incidence rates, characteristics of acute and recurrent sports injuries during official training period and thus these results could provide relevant information for the sports injury prevention at Korea National Team player.

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.

Purpose In the meantime, there have been not many samples that require dilution, and it has been difficult for the examiner to set an appropriate dilution multiple for RIA test item and report the results. Accordingly, it was judged that it was necessary to set the maximum dilution multiple for each test and to verify the upper limit of the clinical reportable range. Therefore, in this study, the maximum dilution multiple for each RIA test was set and the upper limit of the clinical reportable range was verified accordingly Materials and Methods Among all RIA tests conducted at Asan Medical Center, the study treated on 30 types of tests which also conduct the dilution test. Data from March to July 2021 were collected and analyzed. The study was conducted on samples subjected to serial dilutions such as X2, X4 or X10, X10², X10³, X10⁴, X10⁵. Results Among a total of 30 test types, 18 test types have more than 5 N values in the tolerance range of 80~120%. As a result of the verification of maximum dilution multiples, the test set to 10⁴ is 𝛼-fetoprotein and thyroglobulin, and the test set to 10³ is CA-125, CEA, and 𝛽-hCG, and the test set to 10² is Free PSA, PSA, CA15-3, SCC, Ferritin, PTH, Cortisol, and Calcitonin. Tests set to 10 include three categories: 𝛽2-Microglobulin, C-peptide, and Testosterone. Conclusion It is expected that it will contribute to improving the quality of nuclear medicine blood tests as the results of dilution experiments can be reported quickly and accurately through the verification of the clinical reportable range.

This study was conducted to compare the muscle strength, muscle power, and H/Q ratio according to energy system contribution in athletes participating in various sports. Subjects of the study were assigned into an Anaerobic Exercise Group (AEG, n=60; Short-Distance, Weight Lifting, Jumping, Throwing, Bowling, Golf) and an Endurance Exercise Group (EEG, n=60; Modern Pentathlon, Field Hockey, Handball, Cycle, Boxing, Rowing) groups. Isokinetic peak torque/body weight% and flexor/extensor ratio at 60, 180 deg/sec of knee extension and flexion were measured using an cybex 770. Data analysis was conducted using an independent t-test and one-way ANOVA. Based on the results of this study, there was higher extension, flexion strength and flexion power in the AEG than the EEG (p<0.05). We also confirmed higher muscle strength and muscle power in short distance and jumping athletes than other athletes participating in other events (p<0.05). However, there was no significant difference within the endurance exercise group. The HS ratio was within a stable range of 50% to 60% in all events. Collectively, the outcomes of this study indicate that routine physiological and performance testing can provide measurable benefits for elite athletes and their coaches.

가상현실(VR)은 현실 세계를 인공적인 기술을 활용하여 실제로 얻기 힘든 경험이나 환경 등을 제공해 인체의 오감(시각, 청각, 후각, 미각, 촉각)을 자극함으로써 실제와 같이 체험하게 하는 기술로써 게임, 영화, 스포츠, 테마파크와 같이 엔터테인먼트 목적으로 개발되는 경우가 많다. 본 논문에서는 Oculus Touch 및 Oculus Rift를 이용한 VR(Virtual Reality) 올림픽 종목의 스포츠를 설계하고 구현한 시스템을 제안한다. 올림픽 종목 중에 인기종목인 양궁, 사격, 테니스, 탁구 총 4가지 종목으로 구성되어 있으며, 특히 AI를 이용한 경쟁을 통해 종목별 스코어(점수)를 평가함으로서 경쟁구도를 형성한다. 또한, 시각적인 자극을 통해 흥미를 이끌어내고 현실적인 환경을 구현함으로써 유저가 실제 현장에 있는 것 같은 느낌을 제공하며, 세계적인 올림픽 스포츠를 유저들이 직접 즐기고 느낄 수 있다.

As economic activities decrease, and the stock market decline due to COVID-19, many people are jumping into stock investment as an alternative source of income. As people's interest increases, many stock price analysis studies are underway to earn more profits. Due to the variance observed in the stock markets, it is necessary to analyze each stock independently and consistently. To solve this problem, we designed and implemented models and services that analyze stock prices using a reinforcement learning technique called Asynchronous Advantage Actor-Critic(A3C). Stock market data reflected external factors such as government bonds and KOSPI (Korea Composite Stock Price Index) as well as stock prices. Our proposed work provides a web service with a visual representation of predictions of stocks and stock information through which directions are given to investors to make safe investments without analyzing domestic and foreign stock market trends.

The goal of this study is an analysis on linkage system between in machinery sector. The development of skill framework and national technical qualification items. This paper researched skills and created the skill level through reviewing domestic & foreign documents, interview with experts and in-depth discussions with expert group focusing on terminologies commonly used in the industrial settings. As a result of skill classification, authors were able to classify skills into three categories in medium-scale classification and 11 categories in small-scale classification, and also into total 42 categories through the re-classification of the small-scale classification. The skill level in the area of machine were classified the skill level in the area of machine into 7 level by reflecting the level system of the korean qualification frameworks, qualification and education course, and skill level in the industrial setting. Based on the skill frameworks, we provided definition of skill and skill group, definition of each different skill, and performance standards by skill and level. also, This paper suggests improving measure of national technical qualification items through analysizing linkage situation between skill frameworks & qualification items.

2018년 2월 9일부터 16일간 열전을 치른 평창올림픽이 25일 막을 내렸다. 강원도 평창, 정선, 강릉에서 종목별로 구분되어 치러진 이번 동계올림픽은 대회 마지막 날까지 컬링과 봅슬레이에서 메달을 추가하여 종합 7위라는 좋은 성적으로 유종의 미를 거두었다. 무엇보다 이번 올림픽은 다른 관점으로 대회를 볼 수 있는 계기를 마련해주었다는 점에서 나에게 더욱 특별했다. 바로 국민들을 감동시키고 여러 패러디 열풍을 통해 응원을 펼친 '컬링' 때문이다.
