This study was carried out to investigated the actual state of rice milling at local milling plants and to find out sources for elevating their milling recoveries in both quantity and quality. At 36 local milling plants located in Gyeongnam and Jeonnam , milling recoveries and head rice recoveries were measured with respect to their different milling systems and rice varieties. Then, the same samples of rice were milled by experimental milling equipments at laboratory, and the two experimental results were compared in order to determine the amount of milling recovery possibly to be increased. The results of this study are as follows ; 1. Milling recoveries of rice at local milling plants were proved to have no relationship with milling systems, and were 68.1% per ent and 72.6percent on an average with new variety and native variety, respectively. 2. The milling recoveries above stated can be elevated 4.5 percent and 2.9percent with new variety and native variety, respectively, by developing and extending technologies of manufacturing and handling rice milling machinery. 3. The head rice recovery of new variety at local milling plants has insignificant differences among milling systems, and was 54.8 percent on the average. With native variety, the recovery by friction type rice polisher was 0.9percent higher than that of friction-abrasive type polisher, and was 64.9 percent on the average. 4. The head rice recoveries of new variety and native can be elevated 5.1percent and 3.9percent, respectively, by the same stimulation above mentioned.

Roadside native vegetation provides important habitat for plants and animals, and provides visual amenity and beauty for drivers and rural areas. In particular, native wildflowers create and maintain attractive landscaping and scenic vistas while help protect and restore the natural environment. However, it is lacking in government policies and guidelines about using native wildflowers for roadside vegetation and alien invasive plants are a major threat to our environment. The purpose of this study is to review the regulations and programs for roadside vegetation, especially native wildflowers in USA in order to learn lessons about developing wildflower policies in Korea. A summary of results follows: (1) the goals of roadside vegetation have been shifted from beautification for pleasant driving experience to sustainable and economical maintenance. (2) Various funds and laws by federal and local government are essential for native wildflower planting and roadside enhancement. (3) Ongoing projects on seed collection and seed banking of native plants are conducted by wildflower research centers to conserve and propagate endangered plants. (4) Recognizing that wildflower viewing holds tremendous potential, increasing local governments try to grow wildflower tourism for economic benefits. In conclusion, we should establish a long-range plan and regulations on roadside wildflowers planting in order to create safe and sustainable transportation corridors in Korea. In addition, more research on wildflower habitat and propagation should be warranted and landscape architects should play a definitive role in providing pleasant driving experiences and promoting wildflower tourism.

As part of the research for the natural products about prostate-related disease, this study screened 159 plant species from 46 families, which included a total of 213 different kinds of local native plants and these plants were tested for the ability to inhibit LNCaP proliferation, an androgen-sensitive prostate cancer cell line, and DU145 proliferation, which is a more aggressive androgen-insensitive prostate cancer cell line. The results indicated that nineteen of 213 types of plants exhibited antiproliferative activity (cell viability < 30%, $500{\mu}g/mL$) on the growth of androgen-sensitive LNCaP cell lines, and five of them exhibited DU145 cell antiproliferative activity (cell viability < 30%, $500{\mu}g/mL$). The methanol extracts of Eurya emarginata (stems), Gleditsia japonica var. koraiensis (leaves), Photinia glabra (leaves) and Elaeagnus macrophylla (leaves) showed antiproliferative activity on both the androgen-sensitive LNCaP cells (cell viability < 30%) and androgen-insensitive DU145 cells (cell viability > 100%). The study also found that the methanol extracts of Styrax japonica (fruits), Aralia continentalis (leaves), Fagus crenata var. multinervis (stems), Thuja orientalis (stems) and Poncirus trifoliate (branches) presented the strongest activity and demonstrated potent antiproliferative activity on both cell lines (LNCaP and DU145 cell viability < 30%).

Ethnobotanical knowledge on native plants is critical on the conservation and management of biological resources. We investigated traditional knowledge of ethnobotanical uses in the Mt. Gayasan National Park area. Interviews were carried out to 189 residents at 176 places, and verified species and usage information was categorized by taxonomic groups, usage, and used parts. The ethnobotanical species of the regions consisted of a total of 275 taxa in 91 families including 105 cultivars. Sunflower family (Asteraceae) is the most widely used family with 30 taxa (7 cultivars). Rose family (Rosaceae, 25 taxa with 11 cultivars), Bean family (Fabaceae, 15 taxa with 11 cultivars), Grass family (Poaceae, 15 taxa with 10 cultivars), and Lily family (Liliaceae, 14 taxa with 4 cultivars) followed. About 50 taxa belong to the Approved Species for Delivering Overseas designated by Korea Ministry of Environment, and six Korean endemic taxa have been traditionally valuable in the regions. Many cultivated species have been utilized for various purposes accompanied local and native plants. The main usage of the plants are edible (175 taxa) and medicinal (168 taxa). Leaves are most commonly used parts (105 taxa), followed by stems (93 taxa), fruits (73 taxa), roots (55 taxa), and wholes (54 taxa). The study does not only provides examples of traditional uses of native plants, but also facilitates conservation of natural resources and sustainable developments of ethnobotanical knowledge for the contemporary human society.

Six local strains collected in Korea and one cultivar (Samdo) introduced from Japan were applied for comparative cultivation to investigate growth characteristics, root yield potentials and saikosaponin contents of root in Bupleurum falcatum L. The one and two year old plants of the native local strains flowered in August 2~3 and July 16~18, respectively, whereas Samdo was late flowering type, being delayed by 18~32days and sustained the growth of above ground parts to the end of November. All the native local strains have similiar characteristics but Samdo was completely different in plant and root type. Local strain collected from Chunchon showed better in growth and root characteristics, consequently resulting high yield of dry roots and saikosaponin contents in both one and two year old plants. The average yield of two year cultivation system was 2.6 times high as 105Kg /10a, compared with that of one year.

Nowadays, local governments have been developing an image to represent their regions' identity. These characters contain unlimited capabilities of utilization and advertising effect that adds to their high value. However, we must consider how effectively the image helps in representing its region because some characters have been produced upon timely basis without consistent long-term planning. This study is to investigate the image and motif of the local government characters from the consumer's perspective. The results are as follows: 1)The images employed by the local governments are not highly preferred and most regions select motifs from their local agricultural products and native plants. 2)The variables that affect the character of the local governments are such as beauty, identity, etc. In conclusion, in order to maximize the local government image, one must improve the design concepts, encourage advertisement of regional festivities and travel commercialization, and advocate the identity and beauty of the local area to the residents and other regional people.

The 18th Winter Universiade will be held in Muju in 1997. It is a good opportunity to inform the local foods of Muju to the inside and outside of Korea. First of all, we carefully investigated the quantity of all kinds of food material, their circulation ability, and cookery per year in Muju. We found about sixty kinds of food as many as restaurant. We presented how to improve such kinds of food as O-Chunk (fish porridge), Minmulmaeuntang, Kochunaengi chungsik, etc. and how to use the special products of Muju such as yam, kochunaengi, wasabi and wild herb. The many kinds of cookery were specialized to cooks through manual and actual skills. And then we held a food contest that twenty-two cooks took part in the contest and there were exhibitted forty-two kinds of foods. Finally, through discussion and food contest, Muju Sanchae Bibimbap (meal which mixed rice with wild plants), Muju Sanchae chungsik (meal which has various wild plants with rice), Muju Kochunaengi Chungsik (meal which has various wild plants and wasabi with rice), Ma Naengmyun (cold yam noodle) and Muju Minmulmaeuntang (hot fish porridge) were recommended.
