급경사면의 세류간 토양침식은 지표면과의 강우입자 충돌에 의한 튀김현상과 면상흐름에 의한 토사이송 능력의 상호작용에 의해 영향을 받는다. 강우운동에너지와 면상흐름이 세류간 토양침식 및 토사유출 발생에 있어서 상대적인 기여도에 대한 연구는 국내뿐만 아니라 전 세계적으로도 미흡하다. 본 연구에서는 강우현상을 재현할 수 있는 강우모의 실험장비와 사면 토양침식 실험을 위한 소규모 토양플롯을 제작하여 실험에 사용하였다. 강우모의에 의한 강우운동에너지는 자연강우의 운동에너지 산정식의 계산결과와 비교했을 때, 약 0.58배의 규모를 재현했다. 강우입자의 충돌을 제어하기 위한 스트립을 토양플롯에 올려놓은 경우와 커버가 없는 나지상태에서 강우모의 실험을 한 경우 사면에서 발생한 지표유출수, 지표하유출수 및 토사유출 자료를 측정하고 분석하였다. 강우강도가 증가함에 따라 지표유출량은 증가하고, 지표하유출량은 상대적으로 감소했다. 지표커버는 지표유출의 첨두유량 발생시간을 지연시켰으며, 지표유출량과 지하수량의 변화를 초래했다. 지표커버에 의해 지표유출량은 평균 1.82배 감소하지만, 토사유출량은 평균 4.93배로 상대적으로 크게 감소하였다. 단위수류력과 토사유출량과 관계를 분석한 결과 강우운동에너지는 토양입자의 튀김현상에 의한 침식을 증가시킬 뿐만 아니라 지표유출수의 유속을 증가시켜 토사이송능력을 가중시키는 것을 확인하였다.

Interrill erosion by the rainfall is divided into a detachment of soil particles by raindrop splash when raindrops having kinetic energy strike on the surface soil and a sediment transport by sheet flow of surface runoff. Rainfall kinetic energy is widely used as an indicator expressing the potential ability to separate the soil particles from soil mass. In this study, the soil erosion experiments of rainfall simulation were operated to evaluate the effects of rainfall kinetic energy on interrill erosion as using the strip cover to control raindrop impact. The kinetic energy from rainfall simulator was 0.58 times to that of natural rainfall. Surface runoff and subsurface runoff increased and decreased respectively with increase of rainfall intensity. Surface runoff discharge from plots of non-cover was 1.82 times more than that from plots with cover. The rainfall kinetic energy influenced on the starting time of surface and subsurface runoff. Soil erosion quantity greatly varied according to existence of the surface cover that can intercept rainfall energy. Sediment yields by the interaction between raindrop splash and sheet flow increased 3.6~5.9 times and the increase rates of those decreased with rainfall intensity. As a results from analysis of relationship between stream power and sediment yields, rainfall kinetic energy increased the transport capacity according to increase of surface runoff as well as the detachment of soil particles by raindrop splash.

The purpose of this study is to research the effect of walking exercise with acaiberry ingestion for 8 weeks on inflammatory markers of middle age women. The participators were aging from 40 to 50 aging healthy women. The first group is classified to ingest acaiberry(AB), the second group is classified to walking exercise with acaiberry ingestion(WE+AB), and third group is classified to just walking exercise(WE). The program was doing walking exercise 3 times per week for 8 weeks. Acaiberry ingestion is after walking exercise for 8 weeks. The amount of the acaiberry is 5g acaiberry dilutes with 100mg water to inhale before breakfast and dinner to monitor CRP of each group before ingest acaiberry and 8 weeks later how to change CRP and cardiovascular disease. Consequently, all of three groups such as: acaiberry ingestion group, walking exercise with acaiberry ingestion group, and just walking exercise group, has positive effect with WBC(white blood cell), Albumin, ESR(erythrocyte sedimentation rate), CRP(C-reactive protein), but Albumin increases very small amount of gaze. Therefore, this study has no longer period time for research, and in the future there should be more concrete and various studies, such as adding more exercise of method, intensity, and measure of ingestion for supporting this study.

운동여부와 운동횟수 그리고 어체 크기에 대한 양식산 어종의 품질판정을 위한 지표를 검색하기 위하여 효소적 방법 즉 ATP 관련화합물과 양식산 활어의 건강한 상태와 칼슘의 노출, 염도의 감소, 산소의 부족, 궁핍 등과 같은 스트레스를 받은 상태를 판단하는 adenylate energy charge (AEC)를 근육의 품질판정을 위한 지표로써 조사하였다. 운동사육구와 비운동사육구에서의 참돔육에 대한 ATP 관련화합물의 변화는 운동 0일에는 ATP함량은 8.62 μmol/g이었지만 20일차에는 8.59 μmol/g으로 운동기간이 길어짐에 따라 ATP의 함량은 약간의 감소를 보였다. 이는 운동이라는 자극요인으로 인하여 ATP의 소모가 촉진되었을 것으로 판단된다. 또한 운동 0일차의 ADP함량은 0.72 μmo1/g이었지만 20일차에는 0.93μmol/g로 ATP의 소모만큼 약간의 증가를 보이고 있다. 반면, 비운동사육구에서 0일차의 ATP함량은 5.78 μmol/g이었지만 20일차에서는 6.31 μmol/g로 운동사육구와 대조적으로 기간이 길어짐에 따라 ATP함량이 약간의 증가를 보여주고 있다. 생리적으로 동물에 가혹한 환경에 두거나 스트레스를 가하면 adenylate energy charge (AEC)가 영향을 받아 변화게 된다. AEC는 (ATP ＋ ½ ADP)/(ATP ＋ ADP + AMP)의 비율로 정의되는데, AEC의 범위는 0∼1사이로써 0은 ATP 관련화합물이 AMP로 전환된 상태를 말하며, 1은 모든 ATP 관련 화합물이 ATP로 존재하는 것을 의미한다. 그러므로, 이들결합의 상관적인 정도는 개개의 세포에서 에너지의 효용성을 측정하는 것으로 이용되고 있다. AEC 수치는 운동수조에서 0.91∼0.92 건강상태가 좋았지만 비운동수조는 0.87∼0.88로 운동수조에 비해 값이 낮게 나왔다. 운동횟수에 관계없이 운동시킨 어육의 AEC는 0.90∼0.91로 건강한 상태였다. 어체크기에 따른 ATP 관련화합물의 변화는 0.7∼0.9kg의 크기를 가진 참돔에서는 ATP 함량이 7.88 μmole/g, 1.5∼l,7kg의 크기를 가진 참돔에서는 ATP함량이 9.61μmole/g로 많았고 다른 크기에서는 큰 차이를 나타내지 않았다. 그리고 ADP함량은 어체의 크기가 증가할수록 함량은 감소하였다. 그러나, 어체의 크기에 따른 ATP관련화합물의 변화는 거의 없었다. 건강도의 지표인 AEC는 0.89∼0.94로 전체적으로 건강상태로 나타났다. 하루 2회 운동시킨 육에서의 ATP함량은 0일차에 8.75 μmole/g, 10일차에 8.46 μmole/g, 20일차에 8.51μmole/g로 약간의 감소를 보여준다. ADP함량은 일까지는 증가하지만 그 이후에는 큰 변화를 보이지 않는다. 6시간 운동시킨 그룹의 ATP함량은 0일차에 8.63 μmole/g, 5일차에 8.52 μmole/g, 10일차에 8.4μmole/g, 20일차에 8.51 μmole/g로 10일까지는 감소하지만 그 이후에는 큰 변화를 보이지 않는다. ADP함량은 0일차에 0.72 μmole/g, 10일차 0.84 μmole/g, 20일차에 0.83 μmole/g으로 10일차까지는 약간 증가하지만 그 이후에는 큰 변화를 보이지 않았다. 참돔의 근원섬유에 있어서 Ca/sup 2+/이 존재할 때 Mg/sup 2+/-ATPase 활성의 변화는 운동시킨 참돔 근원섬유의 Mg/sup 2+/-ATPase 활성은 0.35μmol Pi/minㆍmg였으며, 비운동구에서 0.34μmol Pi/minㆍmg으로 운동시킨 참돔의 육에서 ATPase 활성이 약간 높은 것으로 나타났다. 운동사육시킨 참돔은 운동기간이 증가할수록 ATPase활성이 증가하여 운동 20일에는 0.42μmo1 Pi/minㆍmg의 함량을 나타내었으나, 비운동사육에서는 큰 차이를 보이지 않고 있다. 근원섬유의 Ca/sup 2+/가 첨가되지 않았을때의 Mg/sup 2+/-ATPase 활성을 나타내었다. 운동시키전에는 각각 0.10μmol Pi/minㆍmg, 0.14μmol Pi/minㆍmg 나타나 비운동구가 운동구에 비하여 Mg/sup 2+/(-Ca/sup 2+/)-ATPase 활성이 높았으며 사육기간동안 활성이 서서히 감소하는 경향을 나타내었다. Ca/sup 2+/-ATPase의 활성 또한 사육기간 동안 큰 변화를 보이지 않았다. 그러므로, 참돔의 운동여부에 따라서 ATPase활성을 살펴본 결과, 운동기간에 따른 약간의 차이는 보이고 있으나, 품질지표로써 사용하기가 어렵다고 판단된다. 효소적인 방법을 이용한 양식산 활어의 품질지표로써 ATP 관련화합물, ATPase 활성은 운동여부, 크기에 따라 객관적인 지표로써의 사용이 어려우므로, 건강도를 측정할 수 있는 AEC의 수치를 적용하는 것이 적합하다고 판단된다. 즉, 양식산 참돔의 AEC 수치가 1∼0.9의 범위에서는 건강한 활어로 상급의 등급을, 0.8∼0.7의 AEC 수치는 중급의 등급으로, 그 이하의 수치에서는 하급으로 적용가능 하다고 판단된다.

In this paper, mobility performance indices are proposed which may be used to estimate characteristics of output velocity space in six-degree-of-freedom parallel mechanism. In order for manipulability and condition number to not suffer from lack of the physical meaning due to dimensional inhomogeneity, output space is partitioned into translational velocity space and rotational velocity space, respectively. In each space, mobility ellipsoids corresponding to unit input space are defined and two types of mobility performance in translational velocity spaces indices are derived. Two types of mobility performance in rotational velocity spaces indices are derived.

The purpose of this study was to verify the effects of long-distance horseback riding on blood lipid, adipokines and inflammatory markers in obese middle-aged women. The subjects of this study were 9 obese meddle aged women and the data analysed using the paired t-test. The result of this study were as follows: First, TC(p<.01), LDL-C(p<.01), and HDL-C(p<.001) were significantly increased after long-distance horseback riding(LDHR). Second, adiponectin was significantly increased(p<.01) and also PAI-1 was significantly decreased(p<.01) after LDHR. Third, IL-6 was significantly increased(p<.01) after LDHR. These results suggest that long-distance horseback riding has positive effect on changes blood lipid, adipokines, and inflammatory markers in obese middle-aged women. Therefore we consider that effects of long-distance horseback riding has partial examine on prevention and therapy of obesity in middle-aged obese women who undergo physical and emotional big changed.
