Structure and dynamics of Abies koreana community in Mt. Gaya were studied to provide the basic data for conservation of Abies koreana community, an endemic species in Korea. A. koreana community of this study site was composed of tree layer (4~7m), subtree layer (2~4m), shrub layer (1~2m), and herb layer (below 1m). The heights of tree and subtree layers were low. Floristic composition showed that this study site was subalpine and dry site. In frequency distribution diagram of diameter classes of major species consisting of A. koreana community, those of both A. koreana and other species showed reverse J-shaped types. From these results, it was estimated that A. koreana community of this site might be maintained continuously as a stable climax state like present state. In the spatal distribution diagram of major species, saplings of A. koreana were established under the canopy of A. koreana and Pinus koraiensis and under the dead tree of A. koreana. From these results, it was known that A. koreana saplings were recruited before the community was disturbed and regeneration was accomplished by advance regeneration pattern, in which these saplings established before occurrence of disturbance fill with open site originated from death of mature tree. Growth of annual rings was variable among individuals, it was estimated that such variation was originated in that growth of each individual relates to microclimatic conditions rather than macroclimatic ones. Ecological longevity of A. koreana in this study site estimated by disturbance types and age of dead trees was about 120 years.

Floristic composition and soil properties were analyzed in red pine($Pinus densiflora$) communities in the limestone areas. Tanyang, Ch ungbuk Province in Korea. The tree layer was composed of $Juniperus rigida, Quercus dentata, Q. mongolica$ and others as well as $P. densiflora$, all of which also appeared in soils of grinite origin The shrub layer was dominated by $Q. dentata, Lespedeza cyrtobotrya, Securinega suffruticosa, Abelia coreana$ and $Uimus davidiana$ for $suberosa$. Among these $A. coreana$ and $U. davidiana$ for $suberosa$ belonged to calcicole plant. The herb layer dominated by $Carex lanceolata$. Soil pH ranged 7.9-8.3. Total nitrogen and available phosphorus content of the soil were lower than those of noncalcareous soils. However, exchangeable calcium and magnesium content were 10 times and 2~3 times greater than those of noncalcreous soils, respectively. The difference of soil texture between top soil(loam soil) and subsoil(sand soil), and higher soil organic matter content than noncalcareous red pine forest soils seemed related to the casts forming activities of earthworms.

Objectives: Traditional Korean herbal formulae are composed of multiple medicinal plants. This situation of multiple-ingredient mixtures has been considered as a major obstacle to new drug development using herbal formulae in the world market, despite the effectiveness of such mixtures. This study reviewed Liv-52 as a representative model of successful drug development using a multiple-herb mixture. Methods: All articles for Liv-52 were collected from the PubMed database. The history, composition of Liv-52, its pharmaceutical efficacy and mechanisms, and data from clinical studies including its market size were analyzed. Results: Liv-52 is composed of seven herbal plants and it is the best known in Ayurvedic medicine for treating liver disorders. Since its 1955 introduction, forty four international papers have been published based on pre-clinical and clinical trials. The efficacy and mechanisms of Liv-52 were intensively studied. Currently, Liv-52 is one of the top-selling products, with over 10 million dollars sales annually, in the world market. Conclusions: These results indicate that Korean herbal formulae could be new global drugs if scientific evidence for efficacy and standardization are produced via literature researches.

As part of the study of the structure and the successional trends of our temperate forests, a quantitative survey was made of the relatively well conserved forest stands on Mt. Kwanak, Seoul. Three community types were observed; the Pinus densiflora-Quercus mongolica community, the Pinus densiflora community, and the Quercus mongolica community. Evidence suggests that the dominance of Pinus densiflora and quercus mongolica will continue in the Pinus densiflora-Quercus mongolica community, however, in the Pinus densiflora community the dominant species, Pinus densiflora, is now being replaced by Quercus mongolica. The trend toward an increased in Acer pseudo-sieboldianum var. koreanum, Fraxinus rhynchophylla, Carpinus cordita, and Acer mono is observed in the Quercus mongolica community. An analysis of the overall composition of the forest reveals that the upper story is mostly occupied by Quercus mongolica and Pinus densiflora, the shrub layer by Rhododendron schlippenbachii and Lespedeza maximowiczii, and the herb layer by Spodiopogon cotulifer and Artemisia keiskeana. Quercus mongolica may cover most part of the forest, gradually excluding Pinus densiflora. Acer pseudo-sieboldianum var. koreanum, Fraxinus rhynchophylla, Carpinus coradata, and Acer mono are increasing in importance with the potentiality of developing into major canopy components. With the diversification of the physical habitat Cephalotaxus koreana and Magnolia sieboldii, the species which had almost completely been eliminated form the forest through the severe interferences, have reappeared.

Herb has been categorized as a special plants from the beginning of human history and used in different medical systems in different cultures. This research has classified soil into 6 kinds that have diverse elements to see to which various kinds of savory(satureja hortensis) adapt well, experimenting from sowing to flowering for around 13 weeks, and also divided indoor conditions to get the result below. In conclusion, growth status of savory depending on the kinds of soil suggest that in indoor conditions the savory if planted in ⑤ bed soil compounded with saprolite and poultry manure grew better than any other condition. On the other hand, the growth status was bad in ① masato, ② clay, ④ bed soil mixed with saprolite, and ⑥ bed soil mixed with clay conditions. Though you can see the immediate effect of soil on the growth of savory, I'd like to reveal the details of how elements of savory operate in which kind of soil and outdoor conditions the goal of this research, in the next research.

Objectives : This study aims to increase efficiency of the prescription similarity analysis method that uses drug composition ratio. Methods : The controlled experiment compared result generation time, generated data quantity, and accuracy of results between previous and new analysis method on the 12,598 formulas and 61 prescription groups. Results : The control group took 346 seconds on average and generated 768,478 results, while the test group took 24 seconds and generated 241,739 results. The test group adopted a selective calculation method that only used overlapping data between two formulas instead of analyzing all number of cases. It simplified the data processing process, reducing the quantity of data that is required to be processed, leading to better system speed, as fast as 14.47 times more than previous analysis method with equal results. Conclusions : Efficiency for similarity analysis could be improved by reducing data span and simplifying the calculation processes.

We surveyed the vegetation of an ecological landscape preservation area (legally protected conservation areas or national parks) and the surrounding areas of Mt. Cheonggye, Republic of Korea, to explore the conservation implications for preservation areas and surrounding transition areas. We calculated diversity indices to identify the properties of the preservation and surrounding areas that are relevant to conservation efforts. We then compared the plant community composition between the areas using field and quadrat surveys in the preservation and surrounding areas. The cover of the dominant species in all tree and herb layers was markedly higher in the preservation area than in the peripheral zones. The species richness indices were significantly higher in the preservation area than in the peripheral zones. Ordination using detrended canonical correspondence analyses showed that the cover of the dominant tree species and rocks could explain the distribution of plant species in the Cartesian space of the ordination. Our results demonstrate that physiognomically designated protected areas match well with ecological data based on diversity indices and ordination analyses and that disturbances in the areas surrounding the ecological landscape of preservation areas can have considerable impacts on plant diversity indices. Hence, the preservation and management of surrounding areas are essential conservation elements for protecting the entire ecological landscape of preservation areas.
