The effect of GINST15, an enzyme fermented ginseng supplement, on hormonal and inflammatory responses to physical stress in humans is unknown. The purpose of this investigation was to examine the constitutive and stress-induced effects of GINST15 supplement on hypo-pituitary-adrenal (HPA) and antioxidant activity in addition to muscle damage. Ten women (age: 38.7 ± 7.8 years; height: 163.81 ± 4.4 cm; body mass 76.0 ± 11.6 kg) and nine men (age: 41.2. ± 9.7 years; height: 177.4 ± 5.3 cm; body mass: 88.5 ± 5.0 kg) participated in a double-blinded, placebo-controlled, counterbalanced within-group study. Participants completed three 14-day treatment cycles with different doses (high: 960 mg; low: 160 mg; placebo: 0 mg) separated by a 1-week washout period. At the end of treatment, physical stress was imposed with intense resistance exercise work stress. Participants provided blood at rest and various time points after exercise (immediately [IP], 30 min [30], 60 min [60], 24 h [+24HR]). Cortisol (CORT), superoxide dismutase (SOD), total glutathione, nonspecific antioxidant activity, total antioxidant power (TAP), and creatine kinase were measured. GINST15 supplementation produced stress-inducible dose-dependent reductions in circulating cortisol and increased enzymatic and nonspecific antioxidant activity. Twenty-four hours after intense exercise, a high dose GINST15, a bioactive ginsenoside metabolite, significantly reduces muscle damage and HPA responses to physical stress in humans; these effects may result from increased antioxidant expression.

토양침식을 예측하는 WEPP(Water Erosion Prediction Project)모델은 연방 정부기관이 토양과 물 보전 및 환경을 계획하고 평가하는데 활용하고자 1985년 8월 차세대 물에 의한 토양침식을 예측하기 위해 만들어졌다. 미농무성 농업연구소에 의해 개발된 WEPP 모델은 경험적인 침식 예측을 위한 도구로써 침투, 유거수, 강우와 물에 의한 토양입자의 분리, 침전물의 이동, 퇴적, 작물의 생장 및 수확 후 잔여물의 분해 등을 포함한 토양 침식과 관련된 많은 중요한 물리적 과정을 모의한다. WEPP 모델은 모델을 구성하는 모듈의 입력자료와 모델을 시험하기 위해서 필요한 자료를 경작지, 초지, 산림 등 광대한 현장 실험 결과들로부터 얻었다. 미국내 여러 농업연구소와 협력 대학 등 수 많은 연구소의 큰 노력으로 모델을 만들 수 있었다. WEPP 모델은 경사지 혹은 작은 유역 규모에 적용이 가능하며, 물리적 모델이기 때문에 미국과 다른 여러 나라에서 중요한 자연자원을 효과적으로 평가할 수 있다. 최근 들어 DOS프로그램으로 만들어진 초기 WEPP모델을 윈도우 인터페이스와 GIS 프로그램을 통합하여 향상시켰다. 또한, 바람과 물에 의한 침식을 통합 예측하는 시스템을 쉽게 이용할 수 있도록 구축 중에 있다. The Water Erosion Prediction Project (WEPP) was initiated in August 1985 to develop new generation water erosion prediction technology for federal agencies involved in soil and water conservation and environmental planning and assessment. Developed by USDA-ARS as a replacement for empirical erosion prediction technologies, the WEPP model simulates many of the physical processes important in soil erosion, including infiltration, runoff, raindrop detachment, flow detachment, sediment transport, deposition, plant growth and residue decomposition. The WEPP included an extensive field experimental program conducted on cropland, rangeland, and disturbed forest sites to obtain data required to parameterize and test the model. A large team effort at numerous research locations, ARS laboratories, and cooperating land-grant universities was needed to develop this state-of-the-art simulation model. The WEPP model is used for hillslope applications or on small watersheds. Because it is physically based, the model has been successfully used in the evaluation of important natural resources issues throughout the United State and in several other countries. Recent model enhancements include a graphical Windows interface and integration of WEPP with GIS software. A combined wind and water erosion prediction system with easily accessible databases and a common interface is planned for the future.
