This study was performed to investigate chemical and functional properties of Glechoma hederacea leaves in respect to its potential use as food material or as a medicinal herb. The chemical compositions on a dry harris were 20.38% in protein, 3.96% in fat, 59.58% in carbohydrate, 15.78% in ash, 5.36% in reducing sugar, 14.11% in total sugar and 0.26% in polyphenol, respectively. The free sugars were mainly comprised of glucose, fructose and sucrose. In fatty acids compositiosn, linolenic acid showed the highest concentration at 45%, while the ratios of saturated to unsaturated fatty acids were 1 : 1.91. Seventeen kinds of total amino acids were determined, with the highest concentration (2,465.71 mg%) of glutamic acid. Among the free amino acids, praline showed the highest concentration (260.09 mg%), followed by glutamine, $\alpha$ -amino adipic acid, glutamic acid and valine. The contents of major minerals were 647.32 mg% in Na, 597.53 mg% in K and 239.75 mg% in Ca. The antioxidative activity of 10% water extract was similar to that of 50 ppm tocopherol. The nitrite scavenging ability reached the highest bevel at pH 1.2 and the lowest at pH 6.0.

Swollen and painful extremities have been treated with herbal baths in attempts to alleviate the symptoms. A popular herbal bath used in China, contains a component called 'bone-penetrating herb' which is believed to facilitate the penetration of herbal substances across the skin to the swollen site, so swollen site, so that pain and swelling will be improved. A search from the Chinese pharmacopedia revealed that 22 different herbs have been traditionally used as 'bone-penetrating herb'. Five of these herbs were available in market and were chosen for experimental studies. Standard diffusion experiments were done to identify the most effective herb among the five, in the penetration facilitation. Glechoma longituba at a concentration of 20% was found to give the best results in the facilitation of Bromophenol blue diffusion across artificial and biological membranes. When compared with one commonly used diffusion facilitator, viz. azone, azone was found to be more effective than glechoma longituba. The encouraging observations support future studies on the basic science behind the use of herbal components as topical agents to treat pain and swelling.

The nutlet morphology and pericarp structure of 14 taxa (4 taxa of the genus Glechoma and related taxa) were studied by light and scanning electron microscopy, and a detailed description of nutlet morphological features for all examined taxa is provided. The shape of the nutlet is ovate to elliptic. Its size is 1.36-3.83 mm in length and 0.80-2.65 mm in width. The largest one was found in Marmoritis rotundifolia, while the smallest one was in Agastache nepetoides. Three different surface types were recognized in the studied taxa based on differences in cell outline and cell boundary relief (rectangular, pitted, and ridged negative reticulate-cell). Three types of trichome (uni-cellular non-glandular trichome, multi-cellular non-glandular trichome, and peltate glandular trichome) were distributed in the nutlets. The pericarp is formed in three layers (i.e., exocarp, mesocarp, and endocarp including sclenchyma tissue), and the pericarp in the studied species is $39.0-237.5{\mu}m$ thick. The morphological and anatomical features (the nutlet shape, surface type, and trichome distribution) in the genus Glechoma and related taxa are described and discussed.

Four cover plants such as Phlox subulata, Glechoma hederacea var. longituba, Sedum middendorffianum and Saxifraga laciniata were evaluated to investigate the effect of companion planting on reducing soil erosion in Chinese cabbage cultivated highland. The experiment was conducted using lysimeters of $5\;m{\times}2\;m$ (length$\times$width) with 5, 15 and 30% slopes. Companion plants except Sedum middendorffianum did not interface with growth of Chinese cabbage Glechoma hederacea var. longituba and Sedum middendorffianum grew faster than Phlox subulata and Saxifraga laciniata in the early growth stage suer transplanting, resulting in fast ground covering, but the ground covering by Phlox subulata and Saxifraga laciniata was delayed because growth suppression by high air temperature during summer season. Soil erosion became severe as increasing degree of slope. Assessments of the four cover plants were conducted in relation to soil conservation characteristic of scenery, endurance to the environment stress, plant growth and weed suppression. From the assessments, Phlox subulata was superior to other intercropping crops tested for reducing soil erosion in highland cultivation of Chinese cabbage.

To evaluate the effect of companion plant (Phlox subulata and Glechoma hederacea var. longituba) on conservation of soil in slopped highland, coverage of crops and soil erosion were investigated with 3 different conditions. The coverage rate of Phlox subulata with Chinese cabbage cultivation was kept on approximately 100% from Chinese cabbage-transplanting to -harvest. The coverage rate of Glechoma hederacea var. longituba with Chinese cabbage cultivation was low at it's early stage, however, reached to approximately 100% at the time of Chinese cabbage harvest. In contrast, the coverage rate of Chinese cabbage cultivation without cover crop, and simultaneous transplanting with Chinese cabbage and cover crop were approximately 60%. Losses of soil and nitrate nitrogen were much lower in Phlox subulata with Chinese cabbage cultivation ($0.1{\sim}0.2ton\;ha^{-1}$, $0.2{\sim}0.4kg\;NO_3{^-}-N\;ha^{-1}$) than those in Chinese cabbage cultivation without cover crop ($20.8ton\;ha^{-1}$, $2.1kg\;NO_3{^-}-N\;ha^{-1}$), and simultaneous transplanting with Chinese cabbage and cover crop ($8.9{\sim}10.5ton\;ha^{-1}$, $1.5{\sim}2.2kg\;NO_3{^-}-N\;ha^{-1}$). Cover plants suppressed the weed occurrence up to about 70%. Live mulching with cover plants set a good effects on weed suppression and reduction of soil and nutrient loss. Therefore intercropping with Phlox subulata will make great contributions to soil conservation in Chinese cabbage cultivated highland.

These day morden cities have serious climatic problems due to enviornmental load caused by excessive development of urbanization. As technological improvement to answer to various ecological disasters and climate changes are also called on the field of construction, inter-disciplinary studies linked to the estabilishment of sustainable energy generation systems and enviornmental control is needed in a consilient point of view. This study aims to analyse optimal site conditions for photovoltaic system and green roof planting through solar radiation simulation in a integrated perspective. In so doing, it seeks to proffer basic study for developing a sound use of roof area that is sustainable in environmental and resources aspects. A computer simulation showed that, in the case of total seasonal solar radiation, summer season resulted 312.5kWh in 35% of total annual solar radiation. This season indicated the lowest radiation rate of the year for direct sunlight in 45.8% of total seasonal solar radiation. Due to such solar radiation simulation, at the largest optimal planting area, Glechoma hederacea var. longituba secured $719.16m^2$ of gross roof area.

Objectives : This study aims to clarify the interpretation of the verse "jinyinhuabohetangxia(金銀花薄荷湯下)" in Zhouxuehai(周學海)'s corrective commentary in the Xiaoeryaozhenzhijue(小兒藥證直訣), by examining traditional pediatric texts in relation to the verse. Methods : For each of the three possible interpretations of the instructive phrase for taking herbal formulas-Lonicera flower with peppermint(金銀花+薄荷), gold and silver with peppermint(金銀+薄荷), and gold coin peppermint(金錢薄荷)-applications of these herbs in the various pediatric books were analyzed to determine the most appropriate interpretation. Results & Conclusions : The formulary composition of Liangjingwan(凉驚丸) and Wusewan(五色丸) seems to sufficiently target the pathology of pediatric convulsion(驚癎) and heart malnutrition(心疳). Furthermore, it seems unnecessary to add Lonicera flower(金銀花) to the gastrointestinal fragility(脾胃虛弱) of the malnourished(疳). Some of the herbal formulas in the pediatrics chapter of the Zhengzhizhunsheng(證治准繩) include Lonicera flower(金銀花) to treat only carbuncles(癰腫, 腫毒), while other books do not include it in their formulas. On the other hand, instructions to take water boiled with gold and silver appear in many texts, including the Xiaoeryaozhenzhijue(小兒藥證直訣), and sometimes include gold leaf(金箔) directly in the formula. Descriptions of gold and silver pots with instructions on how to make herbal formulas were found as well, which supports what Zhouxuehai(周學海) commented on the Xiaoeryaozhenzhijue(小兒藥證直訣). Although gold coin peppermint(金錢薄荷) is currently used as Lianqiancao(連錢草) in China, it was difficult to verify its identity as Jinqianbohe(金錢薄荷), which seems to have been recognized as a type of mint in the past. No reported anticonvulsant studies of Lonicera flower(金銀花), gold and silver(金銀), and Lianqiancao(連錢草) were found. Peppermint(薄荷) was ubiquitous in instructions for taking herbal formulas treating pediatric convulsions. Therefore, the instruction to take water boiled with gold and silver, or to take the herbal medicine in water boiled in a gold and silver pot, rather than using Lonicera flower(金銀花), could be considered as an interpretation closer to the original author's intent.

The objective of this study is to investigate the quality characteristics of Yanggaeng by using the functional properties of Glechoma hederacea (GH). Sample was dried at $50^{\circ}C$ dry oven. The results of the study were as follows : The Phenolic compounds of GH was $12.99{\pm}0.3mg/g$ in water extract (GHWE), $3.14{\pm}0.07mg/g$ in 70% ethanol extract (GHEE). The antioxidant activity of GH was determined in various phenolic concentrations at $50-200{\mu}g/mL$. DPPH activities of GHWE and GHEE were 77.16-78.24% and 73.04-77.00%, respectively. The ABTS were 84.35-99.75% and 83.74-99.55%. The anti-oxidant protection factor (PF) were 1.54-1.62 PF and 1.62-2.09 PF and TBARS were 42.93-94.09% and 91.05-95.19%, respectively. Tyrosinase inhibitory activity of GHEE increased concentration dependently. Hyaluronidase inhibition activity of GHEE and GHWE, showing that there were increasing pattern depending on the increases in the phenolics concentration of GH. In texture, Hardness and springiness were significantly different in the control and 2% groups, but cohesiveness and chewiness did not show any significant difference. In color, L value decreased in proportion to concentration, and a and b values did not change. Sensory characteristics showed that the 1% group had the highest score and the 2% group had the lowest score. Thus, when the GHP Yanggaeng was prepared, in consideration of its sensory characteristics, and at appropriate concentration on below 1%.
