국민 공통 기본 교육과정은 교과, 재량활동, 특별활동으로 편성된다. 본 연구에서는 중학교에서 특별활동 수학반을 전일제로 운영하는 사례를 중심으로, 수학반의 운영 방법, 연간 프로그램 구성 및 구체적인 자료의 개발, 학생들의 수학반 활동을 구체적으로 고찰하였다. 이를 통해, 현재 중학교에서 널리 운영중인 전일제 형태의 수학반 운영의 개선 및 체계화를 위한 기초자료를 제공하고, 교육과정 운영의 내실화를 위한 시사점을 줄 수 있을 것으로 기대된다.

Objective: The purpose of this study is to improve TPI OnBaseU Power Test and golf performance by conducting CrossFit power training. Method: Three male golf players from University B participated in this study. They had 3 to 4 years of golf experience and participated in 8 weeks of CrossFit power training. Results: OnBaseU Power Test: There was a lot of improvement in Sit up throw (27.9%) and Chest pass (10.58%), but there was not much improvement in Baseline Toss (R5.9, L9.8%) and Vertical Jump (4.1%). Golf shot data: There was a very statistically significant difference in Club speed, Ball speed, and Total Length, which are related to speed, and there was no difference in Club path and Smash factor, which are related to accuracy and posture. Conclusion: CrossFit power training was effective in improving TPI OnBaseU Power Test and golf performance (Club speed, Ball speed, Total Length).

PURPOSE: To determine the effect of weight ball throw training as a preparatory exercise before golf practice for 8 weeks on back muscle strength, weight shifting of lower body, head speed of club, and driving distance of amateur golfers. METHODS: A total of 18 subjects were randomly assigned to the experimental group (n=9) and the control group (n=9), respectively. For the experimental group, Weight ball throw training was provided to the height of waist and shoulder similar to golf swing with the following schedule: 3 kg weight ball throw training from the first week to the 4th week; 5 kg weight ball throw training from the 5th week to the 8th week. Before and after 8 weeks of training, back muscle strength, weight shifting of lower body, head speed of club, and driving distance of subjects in the two groups were measured. RESULTS: The experimental group showed significant differences in rotational back extension torque, weight shifting of lower body, head speed of club, and driving distance during golf swing (p<.05). However, the control group only showed significant difference in driving distance during golf swing (p<.05). Back extension torque, weight shifting of lower body, and head speed of club showed significant differences between the two groups during golf swing (p<.05). CONCLUSION: Weight ball throw training can positively change rotational back muscle strength, weight shifting of lower body, head speed of club, and driving distance of amateur golfers. Therefore, it might be used as an effective warming up exercise for amateur golfers.

It is important to improve the initial launch conditions of golf ball at impact between golf club and ball to get a long flight distance. The flight distance is greatly influenced by the initial launch conditions such as ball speed, launch angle and back spin rate. It is also important to analyze the mechanism of ball spin to improve the initial conditions of golf ball. Back spin rate is created by the contact time and force. Previous studies showed that the contact force is determined as the resultant force of the reaction forces normal and tangential to the club face at the contact point. The normal force causes the compression and restitution of ball, and the tangential force creates the spin. Especially, the tangential force is known to take either positive or negative values as the ball rolls and slides along the club face during impact. Although the positive and negative tangential forces are known to create and reduce the back spin rate, respectively, the mechanism of ball spin creation has not yet been discussed in detail in the literature. In this paper, the influence of the contact force between golf club and ball is investigated to analyze the mechanism of impact. For this purpose, the contact force and time at impact between golf club head and ball are computed using FEM and compared with previous results. In addition, we investigate the impact phenomenon between golf club head and ball by FEM and clarify the mechanism of ball spin creation accurately, particularly focusing on the effect of negative tangential force on ball spin rate.

이 연구는 광주광역시 C대학 도서관에서 운영하는 독서토론클럽 참여자의 인식을 조사하고 평가하기 위한 것이다. 이를 위해 참여자의 인구통계학적 특성, 참여기간과 태도에 따른 참여효과 차이, 독서토론클럽의 문제점에 대해 조사하였다. 자료의 수집은 설문조사와 인터뷰를 통해 이루어졌으며, 분석 결과 참여기간이 1년 미만인 참여자보다는 3년 이상인 참여자가, 참여태도가 나쁜 참여자보다는 좋거나 매우 좋은 참여자의 참여효과가 더 높은 것으로 드러났다. 또한, 향후 대학도서관 독서진흥프로그램의 운영에 일조하기 위해 독서토론클럽 문제점을 분석한 결과를 토대로 활성화 방안을 제시하였다.

본 연구는 한국인에게 맞는 강점 척도의 개발과 타당화를 목적으로 한다. 연구 참여자는 남녀 성인 355명이었으며, 측정도구는 HEXACO 성격 검사, 삶의 만족도 척도, 긍정적 부정적 정서 척도, 행복추구경향 척도를 사용하였다. 탐색적 요인 분석 결과, 25개의 하위 영역은 4개의 상위 요인 구조를 보였다. 한국인 강점 척도는 높은 내적일치 신뢰도를 보였고, 각각의 하위영역와 개념적으로 유사하기 때문에 높은 상관을 나타내리라고 기대하였던 관련 측정치들과 예상대로 높은 상관을 보였다. 본 연구에서 개발된 한국인 강점 척도는 신뢰롭고 타당한 측정 도구로 평가되었으며, 개인의 대표강점의 발견과 활용에 관한 임상적 실제, 연구 및 교육에 효과적으로 이용 가능할 것이다.

Functional inner-wear being currently sold is being made without regard to the characteristics of various sports events. The purpose of this study is to identify this problem and to investigate the effect of sports taping on golf swing when wearing functional inner-wear. The subjects of this study were 8 male golfers belonging to Korea Professional Golf Association, and Launch monitor and Trackman were used to find out golf club action, ball pitch, distance, etc. There are three types of clubs: driver, wood, and iron, and the first experiment was carried out using only functional inner-wear. In the second experiment, we experimented with functional inner-wear after sports taping, and we compared and analyzed the distance depending on each experiment, the speed of the ball and the club, and the accuracy of the club face. The results of the study were as follows. As a result of driving distance, according to the presence of sports taping on functional inner-wear, there was a statistically significant difference in the driving swing and wood swing, for club and ball speed, there was a statistically significant difference only in the driving swing. Regarding the accuracy by the presence of sports taping on inner-wear, there was a statistically significant difference in the driving swing, wood swing, and iron swing. In conclusion, the sports taping in the functional inner-wear had a positive effect on golf performance improvement, and we hope that golf inner-wear these two specifications combing will be developed in the future.

2017년까지 500개의 비즈쿨 학교가 지정될 예정이다. 비즈쿨 학교로 지정되면 여러 가지 활동중에서 창업동아리 활동이 활발히 이루어질 것이다. 특히 특성화 고등학생들의 창업동아리 활동은 창업에 대한 기본적 개념과 창업프로세스를 이해할 수 있도록 기회를 제공할 뿐만 아니라 이를 진행하는 과정에서 창의성, 리더십, 협동심, 문제해결 능력 등을 신장할 수 있어서 졸업 후에도 진로를 결정하는데 도움이 된다. 이에 따라 실제 창업동아리 활동의 유무에 따라 창업의지나 진로성숙도에 차이가 있는지를 가설로 설정하여 검정하였다. 총 274명의 특성화 고등학교 학생들을 대상으로 검증을 실시하였다. 검증 결과 창업의지와 진로성숙도(결정성/확신성)에서는 유의미한 차이가 있는 것으로 나타났다. 이는 청소년 대상 창업교육이나 진로교육은 기본 방향은 청소년을 대상으로 진취적인 사고와 창의성을 바탕으로 자기주도를 기반한 문제해결중심형 창업동아리 활동이 필요함을 제안한다.
