본 연구에서는 성장호르몬 대사에 관여하는 유산소 운동과 L-arginine에 대한 효과를 알아보기 위하여 고지방 식이 섭취로 유도된 비만 흰쥐에서 트레드밀 운동과 L-arginine (150 mg/kg) 투여가 체중, 식이섭취량, 성장호르몬, 그리고 복부비만에 미치는 영향을 관찰함으로써 비만에 대한 효과를 알아보고자 하였다. 본 연구의 대상은 6주령 된 Sprague-Dawley계 수컷 흰쥐 50마리를 구입하여 32마리를 무작위 추출하여, 지방이 전체 칼로리의 60%를 차지하는 고지방식이사료(high fat diet # D12492, Reserh Diets Inc., USA)를 섭취한 고지방식이군(high fat diet; HF)을 대조집단으로 하여 트레드밀 운동(EX)과 L-arginine 투여(LA)가 체중 및 지방대사에 미치는 영향을 알아보기 위하여 HF군(n=8), HF+EX군(n=8), HF+LA 섭취군(n=8) 및 HF+EX+LA 섭취군(n=8)의 각 4개 군으로 분류하여 12주간의 실험을 실시하였다. 체중의 변화와 식이섭취량은 사전, 4주, 8주, 12주를 측정하여, 집단 및 시기 간의 이원반복변량분석을 적용하였으며, 그룹별 성장호르몬 농도와 복부지방량 측정은 일원변량분석을 적용하였고, 사후검증으로 Tukey`s 테스트를 적용하였다. 통계적 유의수준은 5%를 기준으로 하였다. 식이섭취량에서는 각 실험집단의 차이가 없었으나, 체중은 트레드밀 운동집단과 L-arginine 투여집단 그리고 L-arginine 투여와 트레드밀 운동을 실시한 복합처치집단 모두 유의하게 감소하였다. 또한 복부지방 조직 무게에서도 트레드밀 운동집단과 L-arginine 투여와 트레드밀 운동을 병행한 복합처치집단에서 유의하게 감소하였다. 혈청 성장호르몬 농도는 대조집단에 비하여 트레드밀 운동집단과 L-arginine 투여집단 그리고 L-arginine 투여와 트레드밀 운동을 실시한 복합처치집단 모두에서 유의하게 증가하였다. 결론적으로 트레드밀 운동과 L-arginine 투여가 성장호르몬의 농도를 증가시키는 방법으로 체중 및 지질 대사에 영향을 미쳐 체지방 형성을 억제함으로써 항비만 효과를 나타낼 수 있을 것으로 사료된다. 또한 트레드밀 운동과 L-arginine 투여를 병행할 경우에 복부지방량에서 단독 투여군에 비하여 더 많은 감소를 보여 운동과 L-arginine 투여의 병행이 체지방 감소에 보다 긍정적으로 작용할 수 있을 것으로 사료된다. The aims of this investigation was to examine the anti-obesity effects of treadmill exercise and oral administration with L-arginine in the high-fat diet induced obestiy rats. It is to analysis changes in body weight, food intake, abdomianl fat and growth hormone. Experimental rats were divided into 4 different experimental groups incluing an HF (high fat control; n=8), HF+LA (high fat+L-arginine oral administration; n=8), HF+EX (high fat+treadmill exercise), and HF+LA+EX (high fat+L-arginine oral administration+tredmill exercise; n=8). Rats were fed experimental diets supplemented with L-arginine at the level of 150 mg/kg/day for 4 weeks. Rats of HF+EX group and HF+LA+EX group performed tredmill exercise training at 60 min/day for 12 weeks. The body weight and abdominal fat mass were significantly decreased in HF+LA, HF+EX, and HF+LA+EX compared with HF group despite that food intake was not differed amone the experimental groups. However, The plasma growth hormone was significantly increased in HF+LA, HF+EX, and HF+LA+EX compared with HF group. These results suggested that the L-arginine oral administration and the regular aerobic exercise made the increase of anti-obesity effect in high-fat diet induced obesity rats.

본 연구는 수상 태양광 발전시설의 설치로 인한 농업용 저수지의 수질변화를 평가하기 위해 경기도 안성시 금광저수지에 위치한 수상 회전식 태양광 발전시설에서 발전시설 설치에 따른 차광구역 6지점과 비차광구역 4지점을 선정하여 1년 동안 총 16회에 걸쳐 차광으로 인한 수질변화를 시간과 수심 별로 분석하였다. 이를 위해 수온, pH, DO, Chl-a, BGA 항목을 0.3 m, 1 m, 3 m, 5 m의 수심별로 측정하고, 표층의 시료를 채수하여 COD, TN, TP 항목을 분석하였다. 연구결과, 금광저수지 내 10곳의 측정지점 간의 관측된 전 수질항목에서 차이는 유의확률(p - value) 0.05 이상으로 유의수준(α=0.05)에서 서로 다르지 않다고 통계학적으로 분석되었다. 이러한 결과를 토대로 측정지점을 차광구역(site 1~6)과 비차광구역(site 7~10)으로 그룹화 후 시간 및 수심에 따른 변화를 확인하였다. 차광구역과 비차광구역 간의 수온, pH, DO, COD, TN, TP, Chl-a, BGA의 계절 및 수심에 따른 차이는 유의한 수준에서 통계학적으로 다르지 않았다(p > 0.05). Chl-a와 BGA의 경우, 7월에 비차광구역보다 차광구역에서 일부 높은 농도가 관측되었으나 이는 기록적인 가뭄과 낮은 저수량, 발전시설 구조물에 부착된 부착조류의 과다성장으로 인한 일시적 현상으로 전체 수질은 통계학적으로 유의할 만한 차이가 없는 것으로 조사되었다. 이러한 결과는 수상 회전식 태양광 발전시설의 설치로 인한 저수지 수면의 차광이 전체 수면적 대비 0.5% 미만으로 일사량 유입 감소효과는 취송 및 방류를 통한 저수지 수체의 혼합 효과 대비 미미했기 때문인 것으로 판단된다. 향후, 수상 태양광 발전시설 설치로 인한 수질변화를 면밀히 연구하기 위해서는 보다 넓은 면적의 태양광 발전시설의 설치로 인한 차광과 함께 장기적인 수질 및 수생태계 관측이 필요할 것으로 판단된다. To evaluate the water quality changes in agricultural reservoir covered with floating photovoltaic solar-tracking systems, the water quality variations with time and depth were monitored on both six sites for light blocking zones and four sites for light penetration zones after the installation of floating photovoltaic solar-tracking systems in Geumgwang reservoir at Anseong-si, Kyeonggi province. For one year with 16 monitoring events, water quality parameters [i.e., water temperature, pH, dissolved oxygen (DO), chlorophyll-a (Chl-a), and blue-green algae (BGA)] were monitored at depths of 0.3 m, 1 m, 3 m, and 5 m, while chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP) were monitored at depths of 0.3 m. Statistically, the difference in all water quality parameters was not significantly different (p > 0.05) at the level of significance of 0.05. Based on these results, the water quality data from light blocking zones (site 1~6) and light penetration zones (site 7~10) were clustered, and were compared with time and depth. As a result, the difference in water temperature, pH, DO, COD, TN, TP, Chl-a, and BGA between light blocking zones and light penetration zones was not significant (p > 0.05) with different time and depth. For Chl-a and BGA, some data from light blocking zones greater than light penetration zones were temporary observed due to the severe drought, low water storage rate, and over growth of periphyton. However, this temporal phenomenon did not impact the water quality. Considering the small water surface area (≤0.5%) covered by floating photovoltaic solar-tracking systems, the mixing effect of whole Geumgwang reservoir caused by Ekman current and continuous discharge were more dominant than the effect of reduced solar irradiance. Further study is warranted to monitor the changes in water quality and aquatic ecosystems with greater water surface area covered by floating photovoltaic solar-tracking systems for a long time.

Wingate test 및 Supramaximal exercise를 이용한 무산소성 운동능력의 측정시 나타난 변인의 관련성을 살펴본 본 연구를 요약하면 다음과 같다. Wingate test시 혈중젖산농도 최고치는 9.04±0.62mM로서 Supramaximal exercise시 보다 유의하게 높았으며, 혈장 LDH 및 CPK활성도는 두가지 운동부하후 모두 유의한 변화는 나타나지 않았다. 근전도상의 적분치, 중간파형빈도 및 평균파형빈도도 유의한 변화는 없었다. 등속성 수축시의 최대토오크는 양쪽 다리 모두에서 초당 60도의 각속도에서가장 높았다. Wingate test시의 최대파워는 등속성 수축시 최대토오크 및 Wingate test시 중간파형빈도의 직접적인 영향을 받는 것으로 나타났으며, 평균파워는 Wingate test시의 적분치 변화, 듣는 쪽 슬관절의 등속성 수축시최대토오크 및 Supramaximal exercise시 혈장 LDH 활성도의 직접적인 영향을 받는 것으로 나타났다. 이상의 결과에서 무산소성 운동능력과 관련지어 그 기전을 살피고자 할 때 체내 화학적 변화, 전기생리적 변화 및 발현능력의 복합성을 고려해야 하며 최대누적 산소결핍량의 활용가능성은 측정강도 결정방법을 중심으로한 계속적인 연구가 요구된다. The present study examined the relationship of variables related to anaerobic capacity with Wingate test and supramaximal exercise. Peak value of blood lactate concentration with Wingate test showeda significantly higher than suprammaximal exercise, and plasma LDH & median power frequency and mean power frequency were not any difference between two tests. Peak torque of isokinetic contractionh on knee joint showed a highest value in 60 degrees of angular velocity among a various angular velocity. Peak power of Wingate test was related to peak torque of isokinetic contraction and median power frequency of EMG with Wingate test, and mean power of Wingate test was related to integrated EMG with Wingate test, peak torque with isokinetic contraction of dominant knee joint and plasma LDH activity with supramaximal exercise. In this result, when it analyzed the mechanism of anaerobic capacity, ti was required the consideration of complexity according to biochemical alteration, electrophysiological alteration and revelation of performance, Appicapability of maximal accumulated O₂deficit was demaned a continuous study with the focus of exercise intensity.
