Activate charcoal (AC) can be utilized as a soil conditioner in agricultural crop areas. This study was conducted to investigate the effect of AC on growth and yield of Zingiber mioga ROSC as affected by different amounts of AC. The results obtained are summarized as follows. Growth characteristics including plant height and leaf length were the highest when activated charcoal added with 10-30%, suggesting that optimum amount of activated charcoal was ranged from 10 to 30%. Growth and enlargement of the root were improved by 10% AC with higher rhizome length and weight.

This study was conducted to develop effective production system in greenhouse for leaves and stems of Angelica acutiloba by using connect pots in 2003 and 2004. Seed germination rate and plant biomass of Angelica acutiloba collected in 2004 were higher than those harvested in 2003. Germination rate of Angelica acutiloba seeds collected in 2003 was 10%, while germination rate of seeds collected in 2004 was above 90%. Especially, plant growth and yield of Angelica acutiloba grown in connect pots sized with 4×4×5cm(length×width×height) were the highest. These results indicate that leaf and stem production of Angelica acutiloba can be improved by using connect pots and optimizing seed collecting time in greenhouse.

Choi,Seong-Kyu,Yun,Kyeong-Won,Shin,Kil-Man 한국자원식물학회 2002 Plant Resources Vol.5 No.3

To develop optimal storage method of root of Zingiberis Rhizoma, which has been grown as major cultural herbal medicine materials, root of Zingiberis Rhizoma, was stored for 10 months with different packing materials and sealing methods. The loss in dry weight as influenced by packing materials and sealing methods was the lowest at vacuum packing and followed by complete sealing methods with transparent polyethylene film. The ratio of root rot during the storage period was not significantly different between packing materials but was significantly different between sealing conditions. Conclusionally, vacuum packing and complete sealing with polyethylene film appears to be optimal for storage of Zingiberis Rhizoma.

This study was carried out obtain basic information for growth characteristics by different age of Dendropanax morbifera in chonnam, such as Yosu, Sunchon, Haenam, Gangjin, Wando. The pH of soil in cultivation area was 5.2 to 5.6 and organic matter was very high up to 10.6% . P205 content of soil in cultivation area was 35.3 to 42.1 mg/L, C.E.S was 13.9 to 14.4 me/100g, and moisture rate was 19.2 to 21.1 % . The flowering of Dendropanax morbifera began from 6~7 years old tree. The flowering date was at 10th of July at Wando. The growth characteristics of 12 years old tree was 929.5cm in stem height, 134.1mm in stem diameter, and 15 years old tree was 1,117.9cm in stem height, 160.8mm in stem diameter. The number of leaf was 13.9 at five years old tree, and the petioles length was 12.6 at five years old tree. Xylem sap can be had at more than 10 years old tree with good growth more than 10 em stem diameter.

Choi,Seong-Kyu,Yun,Kyeong-Won,Chon,Sang-Uk,Seo,Young-Nam,Seo,Kyoung-sun,Kwon,Byung-Sun 한국자원식물학회 2003 Plant Resources Vol.6 No.3

This study was conducted to produce effectively more leaves of Angelica acutiloba through year-round production system by using various mulching materials and polyethylene(PE) tunnel. Soil temperature by covering treatment was higher in PE mulching and PE tunnel than in rice straw mulching, especially showing the highest temperature in PE tunnel from April through May. Water content of soil was higher in PE mulching than in non-mulching. Leaf production of Angelica acutiloba through year-round production showed the highest in PE tunnel and root production in PE mulching. These results suggest that leaf production of Angelica acutiloba can be maximized through PE tunnel cultivation system.

Background and objective: This study was conducted to determine the preferences in flower jewelry by conducting a surveyusing conjoint analysis on the perception of flower jewelry and provide basic data for development of flower jewelryproducts. Methods: For the conjoint analysis, four attributes of flower jewelry were selected. Attribute 1 was related to the mainmaterial of flower jewelry, presented in three levels: cut flowers, potted flowers, and processed flowers. Attribute 2 wasrelated to wearing area presented in five levels of wearing area: hair, neck, ear, arm (wrist) and chest (shoulder). Attribute3 was related to price provided for selling products in flower shops, presented in three levels: less than 30,000 won,50,000-70,000 won, and more than 100,000 won. Attribute 4 was related to flower jewelry wearing time, presented inthree levels: less than 6 hours, 12-24 hours, and more than 24 hours. After extracting 25 profiles through orthogonaldesign, a questionnaire survey was conducted on 402 general participants, from which the responses of 343 participantswere analyzed. Results: By attribute of flower jewelry, the respondents attached most importance to price (34.14%), followed by wearingarea (29.18%), wearing time (18.51%), and material (18.17%), proving that the general public attached most importanceto price (Pearson's R = .987, p = .000). The preference in levels by attribute was highest for processed flowers in material,less than 30,000 won in price, hair in wearing area, and 12-24 hours in wearing time. Conclusion: By making flower jewelry based on the results of the analysis, it would be possible to help increase items soldin flower shops as well as their income.

Objective: Recently scolopendrid aquacupuncture has been a good effect on pain control but it has not been known about clinical safety. So, In order to prove the clinical safety of scolopendrid aquacupuncture, We have observed the physical reac-tion and clinical pathology test after scolopendrid aquacupuncture treatment. Methods: We analyzed physical reaction and clinical pathology test before and after Scolopendrid aquacupuncture treatment of 30 patients suffering from pain, who admitted department of Acupunture and Moxibustion, College of Oriental Medicine, Won-Kwang University Kwangju hospital. Results & Conclusions: The results were summarized as follows. 1) The distribution of sex was 14 males and 16 females, and the average of patients age was 46.2 years. 2) The distribution of symptom was lumbago, lumbago with radiating pain, nuchal pain and knee joint pain. 3) In the 30 patients treated with Scolopendrid aquacupuncture, hematologic test did not show remarkable change. 4) In the 30 patients treated with Scolopendrid aquacupuncture, Liver function test(AST, ALT, ALP) showed a slight decrease on the contrary, and abnormal rate showed a decrease of 1.0%(from 3.3% to 2.3%) compared with previous study. 5) In the 30 patients treated with Scolopendrid aquacupuncture, Renal function test(BUN, Cr) and abnormal rate(from 2.5% to 2.0%) showed a slight decrease on the contrary. 6) In the 30 patients treated with Scolopendrid aquacupuncture. Electrolyte were normal range before & after treatment. 7) In the results of the Urine analysis of 30 patients, Leukocyte, Protein. Glucose, Keton, Bilirubin, U-bilinogen were not detected before and after Scolopendrid aquacupuncture treatment, and the rest almost made no difference. 8) In the Physical reactions, all of the patients complained of pain of body partially, only one patient showed reddish and itch, but symptoms like those were entirely disappeared within 24 hours and whole body pain, swelling, headache, dizziness, fatigue and nausea was not observed.
