PURPOSE: To evaluate the effects of resistance exercise with intermittent blood flow restriction (BFR) on the muscle thickness, maximal strength, and isokinetic muscular function (strength, power, endurance) in high school field hockey athletes. METHODS: The BFR group (n=10, 16.1±1.1 years, 172.8±3.9 cm, 66.2±3.9 kg) and the control (CON) group (n=10, 16.60±1.17 years, 172.5±2.3 cm, 65.7±2.9 kg) participated in the same nonlinear periodic training program, however different weight loading (%RM) was applied depending on whether or not BFR was applied. In this study, the systolic blood pressure was set as the blood flow compression strength, and a BFR prop belt was used. After the 8-week training period was over, the degree of improvement in body composition, 1 repetition maximum (1RM), and isokinetic muscle function among groups was compared to determine the effect of training by blood flow restriction. RESULTS: The cross-sectional area of the thighs of athletes who applied BFR was significantly increased than that of the CON (p<.05). In the isokinetic results, athletes with BFR showed higher 1RM than the CON (p<.05). but there were no differences in muscle power and endurance (p>.05). In the results of improving the muscle strength (1RM and 60º/sec) of the athletes who applied the BFR, there was no significant difference between the groups in muscle power and muscular endurance. CONCLUSIONS: Non-linear strength training with BFR might be considered to be an effective method for improving muscle hypertrophy and maximum strength of athletes. The muscle endurance and muscle power method once a week, which was not effective in improving the muscle power and muscular endurance of high school male hockey players

PURPOSE: To assess the agreement between maximal oxygen consumption (VO2max) measured directly when performing the maximal graded exercise test (GXT) and estimated VO2max from two different equations in Korean male and female youths aged 13-18 years. METHODS: Sixty-six adolescents (15.3±1.7 years, 166.0±7.8 cm, 58. 7±10.0 kg, BMI 21.2±2.7) performed GXT on a treadmill and Astrand-Ryhming step test (AR test) to measure VO2max and VO2max estimates, respectively. The participants wore a portable device (Polar CS300) to measure heart rate (HR) during the tests. RESULTS: Correlation coefficients (r) between VO2max of the equations and VO2max of the measured value were 0.321 (p<0.05) and 0.713 (P<0.01), respectively. The mean difference ranged from -0.234 mL·kg-1 ·min-1 to -3.63 mL·kg-1 ·min-1. The AR equation tended to be somewhat underestimated measured VO2max. The standard error of the estimate (SEE) ranged from 4.95 mL·kg-1 ·min-1 to 7.60 mL·kg-1 ·min-1, and the percentage error (%Error) ranged from 26.6% to 193.7%. CONCLUSIONS: The results of this study suggest that the equation provides the closet agreement with directly measured VO2max in Korean male and female youths aged 13-18 years. A further study needs to develop a step test estimation equation targeting adults and elderly people in which validity and reliability are secured.

PURPOSE: The aim of this study was to evaluate the power change when increasing angular velocity from 180°/sec to 240°/sec in male athletes during isokinetic knee joint tests. METHODS: Isokinetic knee extension/flexion tests were conducted at angular velocities of 60, 180, and 240°/sec in 74 adult male athletes from three sports (judo, field hockey, and canoeing). A basic physical fitness test and an anaerobic Wingate test were also conducted. Peak torque (Nm) and power (watts) were compared for different angular velocities. Correlation analysis was used to evaluate the relationship between power change. In addition, fitness and Wingate test results were compared between groups divided by increased/decreased power change. RESULTS: As angular velocity increased, peak torque decreased and muscle power significantly increased (p<.05). The rate of power increase/decrease generated when the angular velocity changed from 180°/sec to 240°/sec showed a significant positive correlation with muscle strength (grip strength, back strength) and peak revolutions per minute (RPM) in the Wingate test (p<.05). The group with an increased power tendency at 240°/sec showed higher Wingate RPM results than the decreased power group (p<.05). CONCLUSIONS: The change in power at high angular velocities may be used to predict an athlete's speed ability, depending on whether their muscle power increases or decreases from 180°/sec to 240°/sec

송정란,이상현,김양중,김수진,김도윤,김창선,박동호 한국운동생리학회 2018 운동과학 Vol.27 No.1

PURPOSE: To develop and validate regression models to estimate maximal oxygen uptake (VO2max) from the new estimation formula based on Astrand-Ryhming step test protocol (AR protocol) in Korean male and female youths aged 13-18 years. METHODS: One hundred twenty participants performed maximal graded exercise test (GXT) on a treadmill and Astrand-Ryhming step test (AR test) to measure VO2max and VO2max estimates, respectively. Participants in the validation study performed the GXT with the stationary metabolic cart and the Astrand-Ryhming step test twice for test-retest reliability. All tests were conducted at least three days apart and in a random order. RESULTS: Mean calculated VO2max (40.43±11.57 mL/kg/min) from the Astrand-Ryhming step test equation was significantly low from that measured during the GXT from stationary metabolic cart (47.32±8.75 mL/kg/min, p<.01). New regression equations were developed from present data to predict VO2max for male and female youths: y=(-13.963×sex)-(0.216×W)-(0.072×HR)+91.296 (r=.772, SEE=5.64 mL/kg/min). The VO2max (47.22±6.76 mL/kg/min) of modified Astrand-Ryhming step test equation showed no significant difference from the VO2max measured through GXT. CONCLUSIONS: It is concluded that this equation developed in this study provides valid estimates of VO2max of Korean male and female youths aged 13-18 years. A further study needs to develop a step test estimation equation targeting adults and elderly people in which validity and reliability are secured.

This study investigates and analyzes the convenience facilities to strengthen or mitigate the Barrier Free awareness and Kindergarten Barrier Free for the kindergarten school staff and the public facility officials of the education office. In addition, to improve the Barrier Free, the improvement facilities of the kindergarten were investigated and analyzed. First, from the institutional viewpoint, it is necessary to amend the existing regulations of the Act for the Promotion of the Convenience Promotion of Disabled Persons, Elderly and Pregnant Women in Korea, and to change the facilities for duties and recommended installation of the kindergarten and the Barrier Free certification standards. Second, in order to apply the Barrier Free certification system to the kindergarten in terms of facility environment, it is necessary to activate the barrier kind of the kindergarten so as to receive the Barrier Free certification by lowering the score of the items difficult to improve due to the terrain or building structure. Third, the perception of Barrier Free is still not high in terms of social awareness. The purpose of this study is to investigate the method of creating a Barrier Free for a kindergarten in the education and living space of children who are the socially underprivileged. Therefore, based on this study, it is anticipated that it will be an opportunity to promote change of Barrier Free in Kindergarten if an attempt is made to improve the Barrier Free certification index suitable for public kindergarten. 본 연구는 단설유치원 교직원과 교육청의 시설담당공무원을 대상으로 장애물 없는 생활환경 인지도와 유치원의 장애물 없는 생활환경 구축을 위해 강화 또는 완화해야 할 편의시설을 조사하였다. 또한장애물 없는 생활환경 조성을 위해 기설 단설유치원의 개선 편의시설에 대해서 조사하여 개선방안을도출하였다. 첫째, 제도적 측면에서 우리나라 현행 「장애인․노인․임산부 등의 편의증진 보장에 관한 법률 시행규칙」을 개정하여 유치원의 의무·권장 설치대상 편의시설과 그에 따른 장애물 없는 생활환경 인증기준을 변경할 필요가 있다. 둘째, 시설 환경적 측면에서 기설 유치원에 장애물 없는 생활환경 인증 제도를 적용하기 위해서는지형 또는 건물 구조상 개선이 어려운 항목은 배점을낮게 조정하여 기설 유치원이 장애물 없는 생활환경인증을 받을 수 있도록 활성화할 필요가 있다. 셋째, 사회 인식적 측면에서 장애물 없는 생활환경에 대한 인지도가 아직도 높지 않은 것으로 나타났다. 교육청 및 인증기관을 중심으로 장애물 없는 생활환경 인증제도에 대한 홍보와 교육을 강화하여야 한다. 기존유치원과 신설유치원의 장애물 없는 생활 환경 조성 방향의 핵심은 보호능력과 안전의식이 부족한 유아의 특성을 감안하는 것이다. 모든 출입구의 높이 차이를 제거하고 자동문을 설치하여 편리성과 안정성을 높이고, 위생시설은 유아가 사용하기 편리하도록 적절한 높이와 공간 확보가 필수적이다. 최근 유아기 공동체 활동이 강화됨에 따라 강당이나 도서관의 각종 편의시설 확충과 피난안전 시설도 강화되어야 한다. 본 연구는 사회적 약자인 유아들의 교육·생활공간인 단설유치원을 대상으로 장애물 없는 생활환경 조성 방안을 연구하였다는 점에서 의의가 있다. 따라서 향후 본 연구를 토대로 기설 유치원에 적합한 장애물 없는 생활환경 인증지표에 대한 개선연구가 시도된다면 유치원의 장애물 없는 생활환경변화를 촉진할 수 있는 계기가 될 것으로 기대한다.

조선후기 서울 무뢰배의 도박

송정란 대구사학회 2019 대구사학 Vol.135 No.-

The late Joseon was a society in which the amusement of gambling was enjoyed by people, regardless of their status. In this period, gambling was popularized in every corner of the country, so it could be regarded as a sociocultural phenomenon. This study identified scoundrels as the core forces leading the amusement of it in Seoul during the late Joseon. Waljas(曰者) and Aksos(惡少), a class of scoundrels caused a variety of troubles, while engaging in entertainment and deviation. There were lower-level officials as the main core forces of scoundrels especially, Harye in Aekjeongseo(掖庭署 下隷)and military officers made trouble due to gambling. It is also valuable to examine Aksos' gambling. Since Waljas often became Gibus(妓夫), gambling was naturally held in Gibang(妓房) or some places provided by the bankers who lent gambling money. In addition, gambling was also opened in the Han-riverside, as it was a scoundrels' main field of action. They did not only lead the amusement of gambling, but also gain economic benefits through usury based on it. They used some methods such as lawsuit, violence and the exchange of grain, in order to the money they lend. They participated in illegal economic activities through gambling, in Seoul during the late Joseon. 조선후기는 신분의 높고 낮음을 떠나서 도박의 유희를 즐겼던 사회였다. 이 시기 도박의 유행은 사회문화현상으로 볼 수 있을 만큼 전국 각지에서 일어났다. 본 연구는 무뢰배를 조선후기 서울에서 도박의 유흥을 주도했던 핵심세력으로 보고 그들의 활동을 살폈다. 무뢰배의 한 부류인 왈자와 악소는 유흥과 일탈을 일삼으며 다양한 문제를 일으키고 있었다. 왈자의 주요핵심세력으로 하급관리를 볼 수 있는데, 특히 掖庭署 下隷와 군관들이 도박을 해서 문제가 되고 있었다. 이와 함께 악소의 도박도 살필 수 있다. 왈자는 妓夫가 되는 경우가 많았기 때문에 도박은 자연스럽게 기방에서 열리거나 혹은 도박자금을 빌려주는 物主가 제공하는 장소에서 도박을 했다. 또한 한강변은 조선후기 무뢰배들의 주요 활동 장소였기 때문에 여기서 도박판이 벌어지기도 했다. 무뢰배는 도박의 유흥을 주도하는 것에서 그치지 않고 도박을 통해 고리대를 하고 경제적 이익을 얻었다. 이들은 빌려준 돈을 받기 위해 소송, 폭력, 환곡과 같은 방법을 사용했다. 무뢰배는 조선후기 서울에서 도박을 통해 불법적인 경제활동을 하고 있었다.
