운동유형이 여성노인의 신체구성 및 뇌기능 관련 호르몬 농도에 미치는 영향

신원태(Shin, Won-Tae),이선영(Lee, Sun-Young),이중원(Lee, Jung-Won) 한국체육과학회 2012 한국체육과학회지 Vol.21 No.4

The purpose of this study was to examine the effect of exercise type on body composition, estrogen, BDNF and amyloid-beta of elderly women. Subjects were 27 elderly women aged 65~75years, classified into three groups(9 in aquarobics group, 9 in coordination exercise group, 9 in walking group). Body composition, BDNF and amyloid-beta were measured at exercise program pre, after 8-week, after 16-week. Data were analyzed by repeated ANOVA method of SPSS/PC<SUP>+</SUP>(ver 18.0), Statistical significance level was a=.05. The results of this study were as follows. Interaction effect appeared within lean mass, percent body fat and estrogen. The differences between groups were not found by post-hoc. However, There were significant differences depending on time within groups. These results suggested that aquarobics exercise and coordination exercise had effects on body composition and, coordination exercise and walking had effects estrogen in brain function related hormones.

운동유형이 여성노인의 뇌기능관련 인자에 미치는 영향

신원태(Shin, Won-Tae),이선영(Lee, Sun-Young) 한국체육과학회 2016 한국체육과학회지 Vol.25 No.2

The purpose of this study was to identify the effect of exercise type on cognitive function and its related variables. Subjects were 30 elderly women over 6 5 years of age. They were divided into three groups(walking, yoga, and korean dance group: respectively 10 women). They exercised 12weeks (40~60%HRR or 12~14 of RPE, 50~60minutes per day, 3 days per week) and cognitive function, neuropsychological factor(PRM, SRM, SSP, and RTI), BDNF, and IGF-1 were measured pre and post exercise. Planned comparisons(ANOVA) were conducted pre exercise and analysis of variance(ANOVA) was used to find differences among groups post exercise. If there was a significant difference, Analysis of covariance(ANCOVA) was used to find difference among groups. Results were as follows. In the case of cognitive function(MMSE-K) and SSP of neuropsychological factor, there were no differences among groups pre exercise, but there were differences among groups post exercise. The order was korean dance≥yoga≥walking. In the case of BDNF, there were differences among groups post exercise. The order was yoga≥korean dance≥walking. Generally, It is thought that korean dance and yoga is better than walking to maintain or improve brain function.

운동유형이 여성노인의 인지기능 및 혈관성 치매 관련 인자에 미치는 영향

신원태(Won Tae Shin) 한국발육발달학회 2015 한국발육발달학회지 Vol.23 No.1

The purpose of this study was to identify whether exercise would have a positive effect on cognitive function and vascular dementia related factors in elderly women and whether there would be an interaction effect between measuring time and type of exercise. Subjects, 27 elderly women, were divided into 3 groups(walking, yoga, and korean dance group: respectively 9 women). They exercised 16weeks and cognitive function and vascular dementia related factors were measured pre and post exercise. Results were as follows. In the case of cognitive function, there were neither main effect nor interaction effect in MMSE-K. And there were interaction effects in MOT and RTI of neuropsychological test, but improving effect was showed only in MOT of walking group. In the case of dementia related factors, there was an interaction effect only in the visceral fat of body composition. And significant increase was showed only in walking group(It is thought that increase was related with the measuring time, autumn). Dementia related blood variables showed neither main effect nor interaction effect. Generally, interaction effects were showed in MOT, RTI and visceral fat, and improving effect was showed only in MOT of walking group.

신원태(Shin Won-Tae),이중원(Lee Jung-Won) 한국체육과학회 2008 한국체육과학회지 Vol.17 No.4

The purpose of this study was to examine the effect on the change of GH, IGF-1, FFA, Lipase with resistant and aerobic exercise in orderly and reverse order. Two type of exercise were repeatedly performed by 10 university male students in orderly and reverse order. The aerobic exercise was performed with 50-60% of HRmax and the resistant exercise with 50-60% of 1RM in 7 parts of body as 3 set as per time. Two-way ANOVA repeated measures was applied to verified the differences between groups before and after performance. The concentration of GH was significantly(p<.05) increased both of two group, especially in the group of resistant exercise. The concentration of FFA was significantly decreased in the group of resistant exercise , while was increased in the group of aerobic exercise. The concentration of IGF-I was significantly(p<.05) increased or decreased both of two group as the change of the concentration of GH. In the concentration of Lipase, it was not significantly different within two groups.

가축분입상퇴비는 가축분퇴비의 운반 및 사용 편리성을 위해 입상화하였고, 입상화된 가축분퇴비는 작물의 필수 영양분을 함유하고 있어 효율적으로 시비하면 화학비료의 대체자원으로 활용할 수 있다. 이러한 이유로 가축분입상퇴비의 시비량 및 시비방법 등 작물적용 기술의 개발이 필요하다. 본 연구는 가축분퇴비의 화학비료 및 유기질비료(유박)의 대체 가능성을 평가하고자 브로콜리를 대상으로 토양화학성, 생육 및 수량 특성을 조사하였다. 시험은 전북 장수군 장수읍 송천리 브로콜리 재배농가에서 진행하였고, 봄 재배는 2021년 3월 22일에 파종하여 4월 15일에 정식하였고, 가을재배는 7월 5일에 파종하여 8월 1일에 정식하였다. 가축분퇴비 및 유기질비료 처리는 정식 전 21일에 질소시비량 기준 50%를 밑거름으로 사용하였고, 3요소 부족분은 화학비료로 밑거름 및 웃거름으로 시비하였다. 시험은 가축분입상퇴비, 가축분분상퇴비, 유기질비료(유박), 화학비료 처리구를 각각 3반복 난괴법으로 배치하여 수행하였다. 시험 전 토양화학성은 pH 6.3, 유기물 함량 57 g/kg, 유효인산 696 mg/kg으로 적정범위 이거나 다소 높은 경향을 나타냈다. 또한 수확기 토양의 pH는 시험 전과 유사하였으며, 유기물은 감소했으나 가축분퇴비 2개구와 혼합유박구에서는 그 정도가 미미하였으며, 유효인산은 봄 재배시 증가한 뒤 가을 재배 후 감소하는 경향을 나타냈다. 수확기의 지상부 중량은 봄 재배시에는 화학비료 처리구에 비해 혼합유박구에서 다소 감소하였고, 가을 재배시에는 가축분분상퇴비구에서 화학비료 처리구에 비해 다소 증가하였으나, 처리구간 유의성은 나타나지 않았다. 식물체 경엽과 화뢰의 무기성분 함량 차이, 수량 또한 처리 구간 현저한 차이는 나타나지 않았다. 이상의 결과로 브로콜리 재배지에서 가축분입상퇴비가 화학비료를 대체할 수 있을 것으로 판단된다.

Addressing Environmental Issues in East Asia Seas Region through International Cooperation

Shin Won-Tae(신원태) 국제지역연구학회 2010 국제지역학논총 Vol.3 No.2

이 논문은 국제 환경문제 해결을 위한 동아시아 국가간 협력 증진 방안에 대해 논하고 있다. 국제 환경문제 중에서도 기후변화는 우리시대의 가장 큰 문제가 되고 있으며 국제사회의 어젠다를 지속가능한 발전에서 녹색성장으로 바꾸는 계기를 마련해 주었다. 녹색성장은 매우 심각한 문제인 에너지와 식량 문제를 해결하기 위한 혁신적인 해결방안을 도입함으로서 달성이 가능할 것이다. 이러한 문제의 해결방안을 곧 해양에서 찾을 수 있다. 해양이 식량, 에너지, 유용자원의 보고라는 것을 인식할 때 우리의 미래는 활짝 열리게 될 것이다. 해양은 서로 연결되어 있다. 따라서, 어느 한 나라의 관리실패는 곧 다른 나라에서 그 영향이 나타난다. 많은 동아시아 국가들이 국제 기준에 못미치는 관리역량을 가지고 있다는 사실을 인식한다면 해양환경 관리를 위해 이들 나라들을 지원하여야 한다는 것을 알 수 있다. 이런 사실을 인식할 때, 한국의 입장에서 국제협력을 위한 전략은 크게 5가지로 분류할 수 있다. 즉, 첫째, 현재 활동하고 있는 국제기구인 PEMSEA와 NOWPAP을 적극적으로 활용하는 방법; 둘째, 동아시아 국가의 담당자들에 대한 능력향상 지원; 셋째, 공정개발원조 자금의 해양과 환경분야에 투자; 넷째, 북한의 환경관리 역량강화를 위한 협력; 다섯째, 한국인들의 국제협력 역량강화를 위한 지원이 될 수 있을 것이다.

Purpose : The Purpose of this study identify that effect of the application of electrical stimuli and US on muscle performance in patient with low back pain. Methods : The participants is 30 female and male with chronic low back pain, and participant assign to transcutaneous electrical nerve stimulation(TENS), interferential therapy(IFC) and ultrasound(US) group at random. The electrical stimulation apply to 20 minute 3 time for 2 weeks. The Measurement was on before and after electrical stimuli application, and measurement item is muscle endurance, muscle power, mobility, flexibility. The comparison between the before and after was Willcox U test, and 3 group after electrical stimuli application compared KusKal-Wallis test.. Result : Three electrical therapy reduced flexibility and muscle endurance, increased mobility. ICT increased statistically significance the muscle power(p<0.05). Conclusions : This study showed that IFC, TENS and US does affect muscle performance in patient with chronic low back pain persons. This indicates that there is an interaction that plays a crucial roles in the electrical stimuli and the muscle power, flexibility and mobility.

젖산역치 수준의 강도를 이용한 운동 프로그램이 운동 중 피로물질 생성에 미치는 효과

윤선아(Youn Sun-A),신원태(Shin Won-Tae) 한국체육과학회 2011 한국체육과학회지 Vol.20 No.1

The purpose of this study was to investigate the effect of exercise program by intensity level of lactate threshold on fatigue material production during exercise. With ten women students at K university aerobic exercise was performed forty minutes 5 times a week for 8 weeks. The conclusion is as follows: The amount of lactate concentration decreased significantly in post than in pre exercise program by intensity level of lactate threshold from 15min to 60min(p<.05). The amount of ammonia concentration showed no difference in post than in pre exercise program by intensity level of lactate threshold. Rating of perceived exertion decreased significantly in post in pre exercise program by intensity level of lactate threshold at 50 min and 60min(p<.05). Therefore, These results show that exercise program by intensity level of lactate threshold could increase exercise performance and decrease lactate concentration during exercise.
