A new taxon, Hymenophyllum wrightii f. serratum C.S. Lee & K. Lee (Hymenophyllaceae), forma nov. was collected and described from forests in Mt. Halla, Jeju-do, Korea. This taxon, H. wrightii f. serratum C.S. Lee & K. Lee (vernacular name: 'Gu-reum-cheo-nyeo-i-kki') was distinguished from H. wrightii f. wrightii by having smaller leaves, broader basal part of leaf blade, broad-ovate laminae, larger sori and serrate margins of lips of involucres. The new taxon's name is based on serrate margin shape of the lips. A Korean name, 'Gu-reum-cheo-nyeo-i-kki', was newly given based on its habitat. Descriptions and its photograph in the habitat are provided along with a key to the species of Hymenophyllum from Korea.

This study was carried out to understand the genetic relationship of three Aloe spp. cultivated in Korea, A. saponaria, A. vera and A. arborescens and a new variant in Korea based on three plastid (matK, trnL-F, rbcL) and one nuclear (ITS regions) DNA barcode markers. A total of 2,420 bp sequence was amplified. Two indels were detected in the trnL region, and also several species specific nucleotide loci were detected in all 29 parsimonious informative sites, and 148 variable sites were detected among four taxa studied while 170 variable and 75 parsimonious sites were detected when other Aloe spp. in worldwide were used. An UPGMA phenogram with 10,000 bootstrap replication showed that the new variant was closest to A. vera. The variant was not morphologically and genetically concurrent with any reported species so far. The clustering of Aloe species were broadly in agreement with previously reported results.

This study was conducted for 10 years from 2012, which is a year before the forest road construction in Minjujisan, to 2022 to analyze annual changes in flora and vegetation before and after the forest road construction and to provide strategies for management. The plant communities in the research sites along the forest road showed the differentiation between slopes with Quercus mongolica community on the northwestern slope and Quercus variabilis and Larix kaempferi communities on the southwestern slope. A total of 212 taxa have increased for number 7 between before and after the construction from a total of 66 taxa (44 families, 59 genera, 51 species, 13 varieties, and 2 forma) in 2012 and 207 taxa (71 families, 153 genera, 176 species, 27 varieties, and 4 forma) in 2015 to 278 taxa (78 families, 172 genera, 242 species, 1 subspecies, 31 varieties, and 4 forma) in 2022. It is noteworthy that the vegetation cover and the introduction of new taxa had been expanded in the sites adjacent to the construction, which is likely caused by the significantly increased amount of light and the introduction of annual herbaceous and naturalized plants after the construction. The results of 10 years of current study reveal that the vegetation cover and the number of new taxa had rapidly increased in earlier years after the construction, slowly decreased later on, and finally formed a stable forest with the increase in the ratio of dominant species. The vegetation cover of the herbaceous layer immediately increased on the slopes along the forest road for a few years after the construction although it had continuously decreased while that of the shrub layer quickly increased. It was shown that on the hillslope the vegetation cover of tall- and low-tree layers increased whereas that of herbaceous and shrub layers rapidly decreased.

Since a hybrid firewall filters packets at a network layer along with providing gateway functionalities at an application layer, it has a better performance than an If filtering firewall. In addition, it provides both the various kinds of access control mechanisms and transparent services to users. However, the security policies of a network layer are different from those of an application layer. Thus, the user interfaces for managing a hybrid firewalls in a consistent manner are needed. In this paper, we implement a graphical user interface to provide access control mechanisms and management facilities for a hybrid firewall such as log analysis, a real-time monitor for network traffics, and the statisics on traffics. And we also propose a new rule script language for specifying access control rules. By using the script language, users can generate the various forma of access control rules which are adapted by the existing firewalls.

Seasonal occurrences and dynamics on the freshwater algae were examined in the upstream of the Yongsan river system with the Kwangju service water area from 1993 to 1994. Three hundred and three taxi were totally collected and composed of 6 classes, 15 orders, 7 suborders, 31 families, 74 genera, 248 species, 48 varieties and 7 forma. Compositions in each algal class were divided in 136 taxi of Chlorophyceae(44.8% ), 109 taxi of Bacillariophyceae(36.0% ), 30 taxa of Cyanophyceae(10.1% ), 21 taxa of Euglenophyceae(6. 9% ),4 taxi of Chrysophyceae(1.3% ) and 3 taxa of Dinophyceae(1.0% ). The occurrence of taxa was a markedly decrease(-62) between summer and autumn, the critically increase(+43) between spring and summer. And also, it was indicated that the high frequency of taxa in summer, but the high standing biomass In winter in spite of low taxi. In general, it has much algal biomass in station 9 and 10, but low in station 4, 5 and 11, relatively. Through this survey, the major dominant taxa in algal biomass, Microcystis aeruginosa, Melosira varians, Synedra ulna and Navicula cryptocephala, they were all above 2.1×10$^{6}$ce11s/1, 13.2% of totals. There are about 10% of new emigrated taxa by season and they showed a remarkable succession. We may suggested that this system was well sustained for the habitat of freshwater algal community with low dominance and high diversity. Twenty three of nuisance algae including of Microcystis aeruginosa, Peridinium willei and Anabaena flos-aquae were distributed as if had low appearance. Of course, many of them were saprobiontic taxa, extraordinary growttung groups depend on organic loading in water system and also it was not showed severe algal blooming phenomenon.

Taxonomic treatment and the identification key for 6 species and 4 varieties from the genus Asarum (Aristolochiaceae) in Korea were presented on the basis of the morphological analyses. Recently the taxonomy of the genus Asarum in Korea is controversial in the definition of species and the establishment of variation range. Our morphological studies supported that the species A. patens, A. misandrum and A. versicolor should be recognized as independent species by the unique morphological characters such as calyx lobes, stylar protuberance and leaf variegation. Second, A. sieboldii var. cornutum, A. koreanum, A. maculatum and A. sonunsanense, regarded as species or variety by different scholars, showed a close relationship with A. sieboldii by the similar calyx characters. Thus, new combinations, such as A. sieboldii for. cornutum, A. sieboldii for. koreanum, A. sieboldii for. maculatum and A. sieboldii for. sonunsanense, are proposed. And A. heterotropoides var. seoulense and A. heterotropoides var. mandshuricum also had a close relationship, thus, new combinations, A. mandshuricum for. seoulense, A. mandshuricum for. mandshuricum, are proposed. Furthermore, it is appropriate that A. heterotropoides var. heterotropoides, only distributed in Japan, is revised into A. heterotropoides as independent species by the unique character from the 2 varieties above. Consequently, the genus Asarum in Korea is classified into 3 species and 7 forma.

The flora survey on Chungnyeongsan and Seorisan was conducted 6 times from 1998 to 2000.817 taxa such as 112 families 415 genera 688 species 1 subspecies 116 varieties 12 forma were recorded. Dominant species in investigated areas was Quercus mongozica and some deciduous broad-leaved species, such as Quercus sp., Acer sp., Fraxinus sp., Carpinus sp., etc. were codominant species in these areas. Pinus koraiensis and Larix teptozepis plantations were also found in these areas. The 16 taxa of rare plants protected by Forestry Service were found in these areas and among them 10 taxa were new populations which had not been recorded in these areas. Discovery of Erunthis stellata, Aconitum koreanum, Paeonia japonica, Scopotia japonica and Acunthopanax senticosus populations indicate that these areas could be regarded as very important one in a biogeographical aspect. Endemic plants were listed 35 taxa and among them 22 taxa including Corydalis maculata, Ulmus macrocarpa, Scrophutaria horuiensis, Cirsium setidens, etc. were new one. Naturalized plants were listed 39 taxa and among them 30 taxa were new one. Lower naturalized index(NI) and higher urbanized index(UI) were recorded compared to those of neighbored areas. There were many kinds of threatening factors fur the plant resources in survey areas, so it is necessary to limit the number of visitors and to introduce the natural relaxation system.

This thesis is concerned with the study of the court attire the typical attire of the ju-dicial world in a point of time that more than 100 years have passed since the introduction of the modern judical system. In recognition of the fact that compiled data of the official uni-form or attire in Korea are insufficient this study placed its signification on the provision of information with focus on attire. As a result of studying court attire in Korea the conclusion was made as follows: Firstly Official attires in Yi Dynasty were divided by wearing embroidered insignia on the breast and the back of an official robe ac-cordint to court rank as well as by wearing Sa-mo in wadded clothes of Dan-ryeong and attaching all sorts of appurtenances including bands and shoes The Minister of Justice was equipped with Ho-pyo Dae-sa-heon equipped with Hae-chi the mayor of Seoul equipped with Un-an In the era of the Kng Young-jo the minister of Justice had no change in its of-ficial robe but the mayer(Pan-yun) of Seoul (Han-sung-bu) had Un-an(wild geese in clouds) changed into Un-hak In the King Ko-jog era the minister of Justice had Ho-pyo changed into Ssang-ho and the mayor of Seoul had Un-hak changed into Ssng-hak on embroideved insignia on the breast and back of an official robe. Laws and regulations concerning court attire began with the In-judgement Full-dress Uni-form Requlation for official-level Clerical Staff below the ordinary staff the Issue No. 14 of the Royal Ordinance in 1906 provided as $\ulcorner$the matter cincerning the Dress Regulation of the Tribunal staff of the Cho-sun Government-General$\lrcorner$the Issue No. 222 of the Royal Ordi-nance in 1911 and changed into$\ulcorner$the Regu-lation on the Dress of Judge Prosecutor At-torney and Law Count Clerk$\lrcorner$the Issue No. 12 of the Supreme Court Rule in 1953 affter the establishment of Korean Government since emancipation from the Japanese rule and into $\ulcorner$the Regulation concerning the Court Attire of Judge and law Court Clerical Staff$\lrcorner$the Issue No. 516 of the Supreme Court Rule in 1966. The judicial system in Korea is the system introduced from the foreign country rather than autogenously developed. And it came to pass through the Japanese colonial period it the beginning that it took root in Korea n was not stabilized in harmony with our native tradition. Accordingly the attare regulation in the judicial system took root in our society by accepting the Japanese attire regulation as it was and judical officials have come to wear the count attire similar to that of the Japanese imperialist era due to its influence though Korean independent goverment was established together with liberation form the Japanese rule. The more regrettable thing is that the current court attire has maintained the form greatly influenced by the U. S. court attire. Fortunately as the judicial circles have recently raised their voices for change in the court attire it has been told that the forma-tion of a meeting for a new court attire has been under way. The birth of the court attire into Which our tradition is sublimated is expected. This study end up with thinking that the must Korean thing is the most global thing in this era that people in the world are clamoring for globalization.

The bamboo, one of staples of South-East Asia, has 1, 250 species in 46 Genus throughout the world South-East Asia, it's main habitat, has 1, 180 species, while South America has about 70 species or so. Major places of it's production in Asia are Korea, southern China, Japan, Malay, Ceylon, Formosa, and Philipine, but of these, Korea, southern China, and Japan are the most famous places for their production of excellant bamboo. In Korea, Kyongsang-Namdo and Cholla-Namdo are known as it's home, occupying 80 per cent of the total area of bamboo production in this country. Kyongsang-Pukdo, Cholla-Pukdo, Chungehong-Namdo, and Kangwon-do are also known as it's minor production. The importance of the bamboo can not be ignored, considering it's role in the industrial development of this country; the bamboo-ware is indispensable for the culture of laver which annually secures a considerable amount of foreign money. But it has long been regreted that the home-made bamboo-ware is far from being able to meet the ever increasing demand in quantity and is forced to be imported annually. In the light of the above mentioned fact, much interested; I undertook the task of investigating the bamboo in this country, Primarily concerned in it's kind and distribution, and could draw the following conclusions as the first phase of my investigation: (1). The amount of the bamboo accumulation in this country, compared with that of pre-worldwar II, is reduced as much as 300, 000 fagots(on fagot amounts to 25 pieces), and now the acreage of the bamboo field is 32, 200$\textrm{km}^2$s. (2). At a mountian peak in Kunoe-myon Wando-kun Cholla-Namdo, I found out a new specis. (Shasamorpha chiisanensis NAKAI Forma wan-Ponia H. P. CHONG) (3). The kinds of the autogenous wild bamboo in this country are as follows; a). 8 kinds in Sinoarundinaria. (5 Spp; 2 For; 1 Var) b). 1 kinds in Pieioplastus. (1 Spp) c). 2 kinds in Pseudosasa. (1 Spp; 1Var.) d) 4 kinds in Sasamorpha. (2 Spp; 1 For.; 1 Var.) e). 4 kinds in Sasa. (4 Spp) In total there are nineteen(19) kinds of autogenous wild bamboo in this country. When adding to this thethirty five (35) species which the japanese has transplanted in Kyongsang-Namdo Forestry Expreimental stations, there are in all fifty four (54) spe ies in this country. (4). As for the distribution of the Northern limitation of the bamboo growing, I found that Sinoarundinaria nigra OHWI var, Henonis HONDA can be cultivated as for as Kosongkun, Kangwon-Do, andSinoarundinaria pubescens HONDA as for as Clung Chong Namdo, and Sinoarundinaria reticulata as far as chung Chong-Pukdo.

This study was conducted to compare the aromatic compounds and the internal quality such as total phenolic contents, DPPH activity, and vitamin C contents in two new forma (red type and dalgom) and gom-chwi (Ligularia fischeri). Total phenolic contents were indicated 137.29mg/100g fresh wt. in gom-chwi, 158.40mg/100g fresh wt. in red type, and 180.82mg/100g fresh wt. in dalgom, red type and dalgom had higher contents than gom-chwi. DPPH activities were appeared similar result in gom-chwi (74.45%) and red type (75.59%), and dalgom (86.26%) had better than others. In vitamin C contents, gom-chwi and red variety had shown very closed results but dalgom had best result (1.81mg/100g fresh wt.). Essential oil contents of red type (0.164% of fresh wt.) and dalgom (0.290% of fresh wt.) had higher contents than gom-chwi (0.060%). Analysis of major components of essential oil by GC/MSD, identified 43 compounds in gom-chwi, 44 compounds in red type, and 31 compounds in dalgom. N-containing compound only detected in dalgom. Comparison of six aromatic compounds for fragrance (a-pinene, ${\beta}$-pinene, ${\beta}$-phellandrene, a-phellandrene, 3-carene, and limonene) was indicated red type had higher contents and dalgom had lower contents than gom-chwi. Dalgom had higher contents of total phenolic, DPPH activity, vitamin C, and essential oil than red type and gom-chwi. This result had shown the dalgom had better characters for new cultivar.
