김건도,민정욱 한국스포츠학회 2020 한국스포츠학회지 Vol.18 No.2
본 연구는 아사이 베리 섭취에 따른 태권도 품새 선수들의 혈중 피로물질 및 산화 스트레스 농도의 변화를 검증하는 데 있다. 대상자는 고등학교 태권도 품새 선수 10명으로 아사이 베리 섭취 그룹(ACG), 아사이 베리 미섭취 그룹(ANG)으 로 반복측정하였다. 트레이닝은 각 60분, 120분간 실시하였다. 그 결과 첫째, 혈중 글루코스 농도는 유의하게 나타났고, 둘째, 혈중 젖산 농도는 유의하게 나타났으며, 셋째, 산화 스트레스 농도도 유의하게 나타났다. 이러한 결과는 태권도 품새 트레이닝 시 아사이 베리 섭취 방법에 긍정적인 영향을 나타낸다. This study, This study, taekwondo training is to verify the change of the blood fatigue substance and oxidation stress of taekwondo poomsae players according to the intake of acai berry. Subjects were composed of repeated measures ANOVA with 10 taekwondo poomsae players. Each training session was conducted for 60minutes and 120minutes. The results showed that blood glucose is low at ACG(Acai Berry Consumption Group) and ANG(Acai Berry Non-Consumption Group). Second, blood lactate is low at ACG and ANG. Third, oxidation stress is low at ACG and ANG. Considering all of these results, it is suggested that the use of acai berry with taekwondo poomsae training has influences on the change of blood fatigue substance and oxidation stress concentration substances.

The purpose of this study is to measure and analyze changes in lumbar muscle strength and pain index after applying other exercise methods for female patients who underwent Posterior lumbar interbody fusion(PLIF) into a resistance exercise group with 14 participants and a self-exercise group with 15 participants. The results are described below. After the application of exercise, the lumbar muscle strength increased by 46.44% in the resistance exercise group (p<.001) at the average value of 7 angles, and the strength increase in the self-exercise group also showed a increase by 16.01%(p<.01). Pain decreased by 66.73% in the resistance exercise group and showed a statistically significant difference (p<.001). It decreased by 15.18% in the self-exercise group and did not show a statistically significant difference. The above results showed that application of resistance exercise and stabilization exercise as a method of improving low back pain after posterior lumbar interbody fusion reconstruction in women increased lumbar extensor strength and resistance exercise had a positive effect on the significant pain reduction.

The purpose of this study is to measure and analyze changes in concentration, brain activity and brain stress for male college students at a college by dividing the participants into an experiment group with 18 participants who applied myofascial release massage for 8 weeks and a control group with 14 participants who did not receive the experimental treatment. The results are described below. Concentration showed an increase by 0.84% after 8 weeks of myofascial release massage treatment, and it decreased by 0.59% in the control group, but there was no statistical significance in both groups. Brain activity decreased by 1.60% in the experimental group with myofascial release massage, and by 5.47% in the control group, but there was no statistical significance in both groups. Brain stress decreased by 3.95% in the experimental group with myofascial release massage, and by 3.27% in the control group, but there was no statistical significance in both groups. The above results showed that when the myofascial release massage therapy was applied, the concentration of college students increased, and the degree of brain activity and brain stress were reduced, which had a positive effect.

Many countries in the world including Korea are trying to reform their medical insurance payment systems to solve the problem of surging medical expenses. Reform of the payment system is mainly focused on the introduction of the Prospective Payment System in order to control surging medical expenses. In general, the Prospective Payment System is recognized as a very effective measure to enhance the efficiency of medical institutions. This study attempts to analyze whether this rationale applies to the new Diagnosis-Related Group- Based payment system in Korea. Korea is currently piloting a new Diagnosis-Related Group-Based payment system to public medical institutions. Whether introduction of the new Diagnosis-Related Group- Based payment system had an effect on the efficiency of medical institutions during the period prior to introduction (2010~2011) and after introduction (2013~2016) was assessed by selecting 28 public general hospitals as the experimental group and 199 private hospitals that had not adopted Diagnosis-Related Group-Based payment system yet as the control group. The results used Data Envelopment Analysis (DEA) and Difference-in-Difference Analysis (DID) and showed that the overall improvement of the efficiency score of medical institutions is observed before and after the introduction of the new Diagnosis-Related Group-Based payment system. However, no statistical evidence was able to be provided as to whether such efficiency improvement is attributable to the new Diagnosis-Related Group- Based payment system. 많은 국가들이 의료비 급증에 대한 문제를 해결하기 위해 진료비지불제도 개혁을 시도하고 있다. 진료비지불제도의 개혁은 의료비를 통제하고자 하는 목적에서 주로 선불상환제 도입을 중심으로 이루어지고 있다. 일반적으로 선불상환제를 도입할 경우 의료기관의 효율성이 향상된다고 알려져 있다. 본 연구는 이러한 이론적 근거가 신포괄수가제도에도 적용되는지 실증 분석한다. 우리나라는 현재 신포괄수가제를 공공의료기관에 한정하여 시범 운영 중에 있다. 본 연구는 신포괄수가제도 도입전(2010년~2011년)과 도입 후(2013년~2016년)를 전후로 실험집단인 종합병원급 28개 공공의료기관과 신포괄수가제가 적용되지 않는 비교집단인 민간의료기관 199개를 대상으로 신포괄수가제도의 도입이 의료기관의 효율성에 영향을 미치는지 분석하였다. 자료포락분석(DEA)과 이중차이분석(DID)을 이용하여 분석한 결과 신포괄수가제도 도입 전후로 의료기관 효율성의 유의미한 향상을 관찰하였지만, 이러한 변화가 신포괄수가제도로 인한 변화인지는 통계적으로 밝히지 못하였다. 이는 신포괄수가제도가 시범 사업 중인 공공의료기관의 공공성 특성으로 공급자 인센티브에 대해 덜 민감하게 반응했을 가능성이 있으며, 따라서 효율성에 미치는 영향이 과소 추정되었을 가능성이 있다.
