1. Objective : The object of this thesis is to find the basis of Constitution assignment of Nogeun(蘆根, Phragmites communis Trin.) used to the medication for Taeyangin. Also, it is to recognize what kind of Constitution of Mogeun(茅根, Imperata cylindrica var. koenigii) is needed to be assigned to. 2. Methods "Dongyi Soose Bowon", 'SinchukBon', 'ChobonKwun', other related Sasang Constitutional Medicine(SCM) books, herbal medicine books such as "Boncho Kangmok", and etc. were compared and researched. 3. Results & Conclusions : 1) Nogeun(蘆根) lowers Qi and harmonizes the body. Because of the effect of lowering soar-Qi(氣), it used to treat the symptoms of Taeyangin's vomiting(噎膈反胃, Stomach reflux due to dysphagia-occlusion). Also Yuksoo Nogeun(逆水蘆恨, Reed growing near the river in low scream) is the basis of considering inhale-gathering Qi effect as a major indication of Nogeun. 2) The theory of classifying White Mogeun as a Tae-eumin Medicinal is based on the effect of Radiating while classifying White Mogeun as a Taeyangin Medicinal is based on the effect of treating stomach reflux(反胃). But both basis are not conclusive and thus requires further study. 3) In "Sasang Geumge Bibang", the first text ever to write only about separate medicinals and Classified Foods (食物類) of each constitution, there were examples of Nogeun and Mogeun's usage based on other pre-existing medical texts. 4) Because White Mogeun is classified as Tae-yangin medication in "Dongmu Yugo", but classified as a Taeeumin's medication in "Dongyi Soose Bowon" 'ChobonKwun' and "Sasang Geumge Bibang", there remains a controversy.

This study was carried out to investigate the free amino acid and derivatives and phenolic acid and flavonoid compositions and contents of hot water and 95% ethanol extracts of Imperata cylindrica Beauvois var. koenigii root. The purpose of this study is to obtain basic data and to confirm their applicability as functional cosmetic and functional food ingredients on extracts. 15 kinds and 9 kinds of free amino acids were detected in both extracts, respectively. 5 kinds and 4 kinds of protein free-amino acid derivatives were detected in both extracts, respectively. Total phenol contents were 116.50 ± 0.06 and 140.10 ± 0.04 mg% in both extracts, respectively. The total flavonoid contents were 31.80 ± 0.03 and 43.90 ± 0.05 mg% in both extracts, respectively. 5 kinds and 6 kinds of phenolic acids were detected in both extracts, respectively. In the case of flavonoid analysis, no flavonoid compound was detected in the hot water extract while taxifolin was identified in the 95% ethanol extract. Based on the above results, the hot water and 95% ethanol extracts of I. cylindrica Beauvois var. koenigii root are rich in free amino acids, amino acid derivatives, phenolic acids and flavonoids which confirm their potential for applications in cosmeceuticals, nutricosmetics formulations and functional foods.

This study examined the coastal sand dune vegetation before and after the construction of an embankment on Anmado Island in order to compare vegetation in relation to the development of islands. A total of 24 species distributed on the sand dunes. 18 species were found to be in common before and after the construction of the embankment, which included Vitex rotundifolia, Imperata cylindrica var. koenigii, Zoysia sinica, etc. The species which were not found in this survey included Rumex japonicus, Setaria viridis, Portulaca oleracea, Artemisia japonica, Poiygonum aviculare, etc, and new species included Arena fatua, Carex boottiana, Lycium chinense, Leonurus sibiricus, Torilis japonica, Solanum carolinense, etc. The washing away of sand brought about the changes in habitat and the increase in naturalized plants, which included Oenothera odorata, Lepidium apetalum, Bidens bipinnata, Erigeron canadensis, Datura stramonium, Xanthium strumarium, Arena fatua, Solanum carolinense etc. In addition, the disturbance to this habitat led to the changes in vegetation. The main plant communities in the surveyed site were classified as Vitex rotundifolia-Imperata cylindrica var. koenigil community, Zoysia sinica-Calystegia soldanella community and Messerschmidia sibirica community. The sand dune vegetation on Anmado Island changed with regard to the community and the composition of species after the construction of the embankment, due to the sand being severely eroded. While Vitex rotundifolia community and Commelina communis community were found before the construction of the embankment, they were replaced by Vitex rotundifolia-Imperata cylindrica var. koenigii community, Zoysia sinica-Calystegia soldanella community and Messerschmidia sibirica community, after the construction of the embankment.

The aim of this study is to provide a fundamental data which can be applied to management conservation, and restoration of coastal sand dune vegetation by determining the classification and distribution of community, and ecological characteristics of the habitat. This research was performed by the Braun-Blanquet's method. The coastal sand dune vegetation of Uido (I.) was composed with 9 communities as follows : Vitex rotundifolia community, Zoysia macrostachya community, Carex kobomugi community, Iachaemum anthephoroides community, Imperata cylindrica var. koenigii community, Carex pumila community, Calystegia soldanella community Messerschmidia sibirica community and Pinus thunbergii community, the evergreen needle-leaved forest. The constancy degree showed high in Calystegia soldanella (77%), Vitex rotundifolia (74%), Carex kobomugi (66%), Zoysia macrostachya (50%) and Imperata cylindrica var. koenigii (47%). However the highest constancy degree Calystegia soldanella has, it turned out to have low net contribution degree (NCD) in each community. In terms of the distribution and growth feature of the composition species in the coastal sand dune, Vitex rotundifolia, Carex kobomuri and Zoysia macrostachya were widely distributed from unstable sand dune to stable one but Iachaemum anthephoroides and Imperata cylindrica var. koenigii were mainly found at the stable sand dune. Carex kobomugi was especially dominant at the unstable sand dune where the sand continued to be deposited. On the other hand, Carer pumila and Messerschmidia sibirica showed regional distributions around fresh water.

To investigate the attributes of seed germination of the plants for greening of river bank slope, low-temperature treatment, chemical treatment, plant hormones treatment, and stratification were conducted using the seeds of 6 herbs growing naturally around river banks, such as Setaria glauca and faberii, Imperata cylindrica var. koenigii, Miscanthus sinensis, Pennisetum alopecuroides, Lespedeza cuneata and the seeds of 3 shrubs, such as Lespedeza bicolor., Rosa multiflora, Spiraea prunifolia for. simpliciflora. The findings are as follows. In case of herbs, Setaria glauca and faberii. have stone seeds. In the treatment with $H_2SO_4$, they were germinated through dormancy breaking, even though there were some differences depending on immersion time, and the germination rate of Setaria faberii was a bit higher than that of Setaria glauca. The germination rate of Imperata cylindrica var. koenigii was low in the treatment with $GA_3$, NAA, and the plant hormone, but the seed germination rate has improved and the germination rate of Miscanthus sinensis and Pennisetum alopecuroides showed the improved seed germination rate in low temperature treatment. In case of Lespedeza cuneata and bicolor, the leguminous plants, the treatment with $H_2SO_4$ was most effective for the improvement of seed germination and the decrease in germination time. Only Spiraea prunifolia for. simpliciflora, the rose among 3 woody plants showed the seed germination rate above 50% without any additional treatment. Thus, it was thought to be appropriate for greening. Rosa multiflora showed the attribute of germination in a dark condition at low temperature through stratification, despite its low germination rate. Based on the results as above, with respect to the greening using directly collected seeds, Miscanthus sinensis, Pennisetum alopecuroides, and Spiraea prunifolia for. simpliciflora are suitable for greening, because they do not need any additional treatment, and Lespedeza cuneata and bicolor are also suitable for greening because it is possible to improve the germination rate and reduce the germination time through the treatment on the seeds before sowing.

To investigate rooting and community forming ability, sod strips of Gramineae such as Miscanthus sacchariflorus (Maxim.) Benth., Miscanthus sinensis var. purpurascens(Andersson) Rendle, Imperata cylindrica var. koenigii(Retz.) Pilg., and Arundinella hirta(Thunb.) Tanaka were planted horizontally at a width of 10~15cm in October 2010 on the bank slope of Kwangju Stream in Korea. Seeds of each species were sown in April 2010 in plastic seedbeds(60cm length ${\times}$ 30cm width ${\times}$ 5cm depth) filled with 4cm of garden soil and grew until October 2010 to form rectangular sod, which then was cut into multiple strips(20cm length ${\times}$ 6cm width ${\times}$ 4cm root depth). Weeds growing on the experiment sites were removed twice a year until those four species had formed a community by 2013. Weeds were not eradicated during 2014 and 2015 to observe whether the community formation can be maintained without weed removal. t-tests on stem numbers and heights in May, July, and September were conducted between 2013 and 2014, and between 2014 and 2015. Stem numbers and heights of the four species in 2014 were significantly decreased(p<0.001) compared with those in 2013 due to weed damage to their growth in 2014. Stem numbers and heights of Miscanthus sacchariflorus(Maxim.) Benth., Miscanthus sinensis var. purpurascens(Andersson) Rendle, Imperata cylindrica var. koenigii(Retz.) Pilg. in 2015 were similar to those in 2014(p>0.05). Stem numbers and heights of Arundinella hirta(Thunb.) Tanaka in 2015, however, were significantly reduced compared with those in 2014(p<0.001) due to weed impact on its growth. After three years of weed removal, a community of each species was formed. Miscanthus sacchariflorus(Maxim.) Benth., Miscanthus sinensis var. purpurascens(Andersson) Rendle, Imperata cylindrica var. koenigii(Retz.) Pilg. were able to establish communities without any further weed removal. Arundinella hirta(Thunb.) Tanaka, however, was not able to maintain its community due to considerable damage to its growth caused by weeds even after three years of weed removal. Miscanthus sacchariflorus(Maxim.) Benth., Miscanthus sinensis var. purpurascens(Andersson) Rendle, Imperata cylindrica var. koenigii(Retz.) Pilg. are more suitable to sod strip plantings on stream bank slopes in terms of the maintenance of community formation without weed eradication. t-test on stem numbers and heights each September during the five year experiment period between sod strip planting and potted plants of the four species were conducted. Stem numbers of strip sod plantings were significantly higher(p<0.001) than those of potted one. Heights of strip sod plantings, however, were significantly lower(p<0.05) than those of the potted samples. Therefore, strip sod planting is more advantageous regarding bank slope erosion protection due to the higher number of stems.

The present paper deals with a research of life form and vegetation of the plants extant in the habitat of endangered Parnassius bremeri in Uiseong, Gyeongsangbuk-do with a view to restore their habitat and create substitute habitats. The research found that there are a total of 130 vascular plants including 47 families, 96 genera, 113 species, 1 subspecies and 16 varieties. In terms of their life form, hemicryptophytes (H) is the majority of dormancy form with 41 species or 31.54%, while $R_5$ is majority of radicoid form with 72 species or 55.38%, gravitational disseminule form ($D_4$) is majority among the disseminule forms with 68 species or 52.31% and erect type (e) is majority of growth form with 57 species or 43.85%. Major constituents of the habitat are Sedum kamtschaticum, Selaginella tamariscina, Orostachys japonica, Arundinella hirta, Cymbopogon tortilis var. goeringii, Themeda triandra var. japonica, Carex humilis, Indigofera kirilowii, Imperata cylindrica var. koenigii, Festuca ovina, Artemisia capillaris, etc., all of species which are in the initial stage of succession and show simultaneously features characteristic of vegetation on the rock. In the habitat 1. Sedum kamtschaticum- Selaginella tamariscina community and Pinus densiflora community are distributed whereas, in the habitat 2. Sedum kamtschaticum-Selaginella tamariscina community, Sedum kamtschaticum-Carex humilis community, Sedum kamtschaticum-Cymbopogon tortilis var. goeringii community and Sedum kamtschaticum-Imperata cylindrica var. koenigii community are growing and in the habitat 3. Sedum kamtschaticum-Selaginella tamariscina community, Selaginella tamariscina community, Sedum kamtschaticum-Indigofera kirilowii community and Quercus acutissima community are seen distributed there, too. Typical of food plants growing in the habitat is Sedum kamtschaticum, found mostly in the rocky area and its surroundings. Absorption plants are those that usually bloom in the season when imagoes emerge. From the research, it becomes evident that the blooming season of Sedum kamtschaticum, obviously a food plant, corresponds exactly to the emergence timing of imagoes. Cirsium japonicum var. ussuriense, Rosa multiflora, Erigeron annuus, Spiraea prunifolia var. simpliciflora are found to belong to these plants.

According to know the botanical flora at the Bieyang Island, located in the frone of Jae-Ju-Island toward west and north, the plant list at the island wa investigated in July, 1955. According to the investigation, the following resume is summarized; 1. Bieyand Island is a small volcano that rose from the sea 942 years ago. Nakai Monosing, a Japanese botanist, had reported 72 species of plants on this island in 1913 indicating 22 residential houses at that time. 2. Resulting on the investigation this time, 184 species of plants are collected. This indicates that the additional 112 species of plants should be added to the number of species that Nakai found. 3. This increase of species of plants, might be caused possibly due to carrying by wind, tidal current, bird, and human, during this time being indicating increase of residential houses from 22 in 1913 to 40 in July 1955. 4. Most of the collected plants are sea-coast and meadow plants. Among them, 44 are thellophytes and 90 hemicreptophytes. This indicates dry climate of the island. 5. The most dominant among them is Imperata cylindrica var., Koenigii. 6. This island could be acceptable for growth of island wood plants, we believe.
