The aim of this study was to investigate the antioxidant effect of medicinal plants used by diabetic patients. Fourteen medicinal plants were selected and antioxidant activity such as 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, inhibition effect of linoleic acid autoxidation and low density lipoprotein (LDL) oxidation, thiobarbituric acid (TBA) value were measured. The Cornus officinalis had DPPH radical scavenging activity of 84.79%, which was higher than the 78.79% for $\alpha$-tocopherol. Rosa rugosa Thunberg, Pueraria thundergiana Bentham, Artemisia princeps var. orientalis and Sasamorpha purpurascens Nakai also had high values. Extracts with higher DPPH radical scavenging activities had higher total phenol concentrations, and positive correlations between these parameters were found. Inhibitory activities of linoleic acid autoxidation, LDL oxidation and TBA value, used as indices of oxidative stress, were observed in most of the selected medicinal plants. The highest inhibitory activity for TBA value was observed in the extract of Pueraria thundergiana Bentham. Rosa rugosa Thunberg (75.50 %), Sasamorpha purpurascens Nakai (74.00 %), and Cornus officinalis (73.00 %) all had high antioxidant activity against linoleic acid autoxidation, similar to that of $\alpha$-tocopherol. The same 3 plants also had high in inhibitory activity against LDL oxidation. Therefore, we demonstrated that medicinal plants used as folk remedy by diabetic patients had antioxidant activity. Especially, Rosa rugosa Thunberg, Cornus officinalis, Pueraria thundergiana Bentham, Arlemisia princeps var. orientalis, and Sasamorpha purpurascens Nakai had high phenol concentrations which resulted in high values for DPPH radical scavenging. These same plants exhibited high values for inhibitory activities for TBA value, linoleic acid autoxidation and LDL oxidation, indices associated with lipid peroxidation.

The study on Musa basjoo planting in traditional gardens in of folk villages and traditional temples was conducted to identify the phenomenon of Musa basjoo planting which frequently appears in paintings and literatures of the late Joseon dynasty and how the cultural custom is being handed down. The result of the study is as follows. As a result of studying state-designated folk villages 6 sites, the custom is being handed down in a few limited gardens including Asan Oeam Village and Seongju Hangae Village. In case of Oeam Village, there are three gardens where Musa basjoo was planted including Seolimbang, Vice Minister's Residence, and Geonjae House where Musa basjoo withered now. In case of Hangae Village, it was found in Bukbi House, Hahoe Residence and Gyoridaek Jinsa's Residence and most of them were planted in front of guesthouses and main building with the assemble-planting method. Musa basjoo planting was confirmed in 39 traditional temples and it was found that Yangsan Tongdosa Temple and attached hermitage Geukrakam are currently prevalent in Musa basjoo planting. Musa basjoo was planted on either side of the stairs of Buddhist sanctums for Buddha and Avalokitesvara Guan Yin of main temples and gwaneum temples with the assemble-planting method and it has a tendency of pair planting. Considering that Musa basjoo is a southern plant, most of Musa basjoo planting was distributed around Jeollanam-do and Gyeongsangnam-do, which is closely related to the isotherm distribution of the Korean Peninsula. Especially, it was found that planting flora was centered on $12^{\circ}C$ of Warmth Index $100^{\circ}$ and annual average temperature.

Agromonia pilosa Ledeb. has been used as a medicinal plant in traditional folk remedy. There are few reports on classification, physiology, ecology and morphological studies of Agromonia pilosa L. in Korea. Therefore, advanced approaches on study and development with this plant would be done urgently. Present stndy was carried out to gain basic information on genetic resources and variation with collected domestic landraces through RAPD analysis in Agromonia pilosa L. Forty two collections of Agromonia pilosa L. from nation-wide area including USA one were analyzed by RAPD test. Molecular marker size by amplified DNA band pattern ranged from 300 to 2,100bp. Among the collection, two landraces of Hadong and Cheonghak-dong showed close relation in genetic similarity. Minimum and maximum value by matrix of 1-F among 26 collected landraces were figured out as 0.365 and 0.827 showing mean value for 0.624, respectively. Those landraces were classified into two groups with cluster analysis by Nei and Li's formula from RAPD-analyzed values, and considerable genetic differences were recognized between two groups.

The results of tracking the symbolism of plants in the introduction factors of Sokhwa(folk painting) are as the following. 1. The term Sokhwa(俗畵) is not only a type of painting with a strong local customs, but also carries a symbolic meaning and was discovered in "Donggukisanggukjip" of Lee, Gyu-Bo(1268~1241) in the Goryo era as well as the various usage in the "Sok Dongmunseon" in the early Chosun era, "Sasukjaejip" of Gang, Hee-mang(1424~1483), "Ilseongrok(1786)" in the late Chosun era, "Jajeo(自著)" of Yoo, Han-joon(1732~1811), and "Ojuyeonmunjangjeonsango(五洲衍文長箋散稿)" of Lee, Gyu-gyung(1788~?). Especially, according to the Jebyungjoksokhwa allegation〈題屛簇俗畵辯證說〉in the Seohwa of the Insa Edition of Ojuyeonmunjangjeonsango, there is a record that the "people called them Sokhwa." 2. Contemporarily, the Korean Sokhwa underwent the prehistoric age that primitively reflected the natural perspective on agricultural culture, the period of Three States that expressed the philosophy of the eternal spirits and reflected the view on the universe in colored pictures, the Goryo Era that religiously expressed the abstract shapes and supernatural patterns in spacein symbolism, and the Chosun Era that established the traditional Korean identity of natural perspective, aesthetic values and symbolism in a complex integration in the popular culture over time. 3. The materials that were analyzed in 1,009 pieces of Korean Sokhwa showed 35 species of plants, 37 species of animals, 6 types of natural objects and other 5 types with a total of 83 types. 4. The shape aesthetics according to the aesthetic analysis of the plants in Sokhwa reflect the primitive world view of Yin/yang and the Five Elements in the peony paintings and dynamic refinement and biological harmonies in the maehwado; the composition aesthetics show complex multi-perspective composition with a strong noteworthiness in the bookshelf paintings, a strong contrast of colors with reverse perspective drawing in the battlefield paintings, and the symmetric beauty of simple orderly patterns in nature and artificial objects with straight and oblique lines are shown in the leisurely reading paintings. In terms of color aesthetics, the five colors of directions - east, west, south, north and the center - or the five basic colors - red, blue, yellow, white and black - are often utilized in ritual or religious manners or symbolically substitute the relative relationships with natural laws. 5. The introduction methods in the Korean Sokhwa exceed the simple imitation of the natural shapes and have been sublimated to the symbolism that is related to nature based on the colloquial artistic characteristics with the suspicion of the essence in the universe. Therefore, the symbolism of the plants and animals in the Korean Sokhwas is a symbolic recognition system, not a scientific recognition system with a free and unique expression with a complex interaction among religious, philosophical, ecological and ideological aspects, as a identity of the group culture of Koreans where the past and the future coexist in the present. This is why the Koran Sokhwa or the folk paintings can be called a cultural identity and can also be interpreted as a natural and folk meaningful scenic factor that has naturally integrated into our cultural lifestyle. However, the Sokhwa(folk paintings) that had been closely related to our lifestyle drastically lost its meaning and emotions through the transitions over time. As the living lifestyle predominantly became the apartment culture and in the historical situations where the confusion of the identity has deepened, the aesthetic and the symbolic values of the Sokhwa folk paintings have the appropriateness to be transmitted as the symbolic assets that protect our spiritual affluence and establish our identity.

For the purpose of recording Folk House Garden, this study was to review the historical value, location, space composition, Placememnt of the Building, garden composition, and management status of Folk House Garden designated as a cultural asset in Jeolla-do and to promote continuous maintenance and preservation in the future and enhance its value. The results of the study are as follows. First, most of them have been influenced by the trend of the times, such as the creation of a modern private garden and the spread of agricultural and commercial development through the garden components influenced by the royal, Japanese, and Western styles. Second, there are differences in the spatial composition of private households and the way they handle sponsorship, depending on the geographical location. When the geographical features were divided into flat and sloping areas, private houses located on flat land were divided into walls, walls were placed around the support area, and flower systems and stone blocks were created. The private houses located on the slope were divided into two to three tiers of space, and the wooden plant, flower bed, and stone bed were naturally connected to the background forest without creating a wall at the rear hill. Third, the size of the house and the elements of the garden have been partially destroyed, damaged, and changed, and if there is a lack of records of the change process, there is a limit to the drawing floor plan. There were many buildings and garden components that were lost or damaged due to changes in the trend and demand of the times, and some of them without records had to rely on the memory of owners and managers. Fourth, the species in Warm Temperate Zone, which reflects the climatic characteristics of Jeolla-do, was produced, and many of the exotic species, not traditional ones, were introduced. Fifth, fine-grained tree management standards are needed to prepare for changes in spatial function and plant species considering modern convenience.

Dendropanax morbifera (Araliaceae) is an endemic species in Korea and distributed in the southern part of Korea. The roots and stems of this plant have been used for folk medicine for the treatment of migraine headache, dysmenorrheal, and remove wind dampness and for Vanishes production. Production of adventitious roots in D. morbifera by in vitro cultures could be used as alternatives materials. Leaf, stem, and root segments from D. morbifera seedling were cultured on Murashige and Skoog (MS) medium supplemented with 3.0 mg/L IBA and 30 g/L sucrose. After 4 weeks of culture, the highest induction of adventitious roots was obtained from the leaf segment. Frequency of adventitious root formation on medium with various kinds of auxins (IAA, NAA, 2,4-D, and IBA) and various concentrations of IBA (0, 0.1, 0.5, 1.0, 3.0, and 5.0 mg/L) was tested. The maximum induction of adventitious root was obtained on medium with 1.0 mg/L IBA. In liquid culture, growth of root was best 1/2MS medium supplemented with 1.0 mg/L IBA and 30 g/L sucrose. Adventitious roots were cultured in 5 L bioreactor containing 1/2 MS medium supplemented with 1.0 mg/L IBA and 30 g/L sucrose and mass-production of adventitious roots was successfully achieved. This study demonstrated for the first time to produce adventitious roots in D. morbifera.
