본 연구에서는 국내 빗물정원과 같은 소규모 저류지공원 적합한 식물을 선발하기 위하여 수변 또는 척박지 녹화용으로 활용되고 있는 초화류 7종을 대상으로 일정 수위를 항시 유지하는 저면 침수와 식물 기부가 물에 잠긴 상태로 3일간 간 침수처리를 반복하는 완전 침수 두 가지 수분 상황에서 식물의 생장 특성을 조사하였다. 습지식물인 갈대는 침수처리에 의한 생장과 생리적 차이를 보이지 않았고, 억새와 리아트리스는 침수처리에 의해 광합성량은 저면관수 시 21.4%, 침수처리 시 60.4%로 낮아졌으나 수분이용효율은 차이를 나타내지 않아 침수 내성종임을 알 수 있었다. 벌개미취와 해국은 침수처리에 의해 생장이 저조했고 광합성량은 82.7% 이상 감소하고 수분이용효율도 29.2% 증가하여 수분스트레스 상태였으나 이후 정상적인 관수에 의해 광합성량과 수분이용 효율이 회복되어 빗물정원 식물로 적합한 식물임을 알 수 있었다. 무늬쑥부 쟁이는 저면침수에서는 광합성효율은 낮아졌으나 수분이용효율은 차이가 없어 습지에 적합하나, 완전침수에서는 수분스트레스가 79.8%로 매우 높았고 침수 후 회복율도 낮아 완전침수에는 적합하지 않은 것으로 나타났다.

Changes in land use and increase in urban energy consumption influence urban life. This study analyzed the characteristics and patterns of urban heat and presents management schemes to generate a comfortable and sustainable urban environment. The study aimed to demonstrate the positive effects of artificial ground greening on improving the microclimate through evapotranspiration using perennial herbs. We have designed a chamber that could control constant temperature and humidity, measure temperature reductions in each plant and changes in sensible heat and latent heat. This study identified Sedum kamtschaticum as the most effective plant in controlling temperature. At 22℃, 3.2℃ temperature reduction was observed, whereas four other plants showed a 1.5℃ reduction. At 25℃, 2.0℃ temperature reduction was observed. On the other hand, the use of Sedum sarmentosum resulted in the lowest effect. Zoysia japonica is the most commonly used ground covering plant, although the temperature reduction of Lysimachia nummularia was more effective at high temperature conditions. Sensible heat and latent heat were calculated to evaluate the thermal performance of energy. At a temperature >30℃, L. nummularia and S. sarmentosum emitted high latent heat. In this study, we analyzed the thermal performance of green roof perennial plants; in particular, we analyzed the evapotranspiration and temperature reduction of each plant. Since the substrate depth and types, plant species, and seasonal change may influence temperature reduction and latent heat of green roofs, further studies are necessary.

General components, amino acids and minerals contained in 7 kind of edible wild grasses were estimated. Samples were collected from the field of Kapyong area, Kyung-ki, Korea. Results of the estimation were summarized as follows ; 1) A relatively large amounts of protein and fat were contained in the edible parts of each sample. 2) The most abundant amino acids in the edible parts of each sample were glutamic acid (26.6%), serine (18.7%), valine (22.4%), respectively. 3) A high level of calcium and iron was found in the edible parts of each samples. Especially calcium was abundant in the leaves of Rumex coreanus Nakai and iron was abundant in the Commelina communis L. Both copper and zinc were abundant in the Sanguisorba officinalis L.

Hepatic ischemia-reperfusion injury (HIRI) is linked with high mortality rate. Several agents have been developed so far to reduce the risk of HIRI. In this study, we investigated the effects of Acanthopanax senticosus extract (AS) on hepatic ischemia-reperfusion. To explore the protective effects of A. senticosus extract injection (ASI) on hepatic ischemia-reperfusion injury rats animal model were used. After the development of HIRI by using clamping method rats were then randomly divided into five groups. Different doses of AS were administered in HIRI rat model. The level of ALT, AST, and MDA content in serum were detected in sham and HIRI groups. The activity of SOD, MPO and Ca2+-ATPase, content of MDA, and cAMP in hepatic tissue were also measured. Expression of Bcl-2 and Bax protein were detected by immunohistochemical staining method. Compared with sham group, ASI has the protective effect on the HIRI model in rats. Blood levels of ALT, AST, SOD, MPO, and MDA were significantly lower in ASI group compared with HIRI. Indeed SOD and Ca2+-ATPase activities, MDA content, and cAMP level were improved in ASI group. Furthermore, Bcl-2 and Bax protein were improved in ASI group compared with only HIRI group. These results suggest that AS may provide potential ameliorative therapy by inhibiting the damage signaling mechanism in hepatic ischemia/reperfusion injury model.
