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.

The purpose of this survey is to investigate and analize the status of flower consumption by city households so that it can provide basic materials for the development of horticulture industry. For this purpose, one thousand housewives were questioned living in six large cities : Seoul, Pusan, Taegu, Inchon, Kwangju and Taejon. The results of the analysis are as follows; 1. The most favorite cut flowers by season were rose, carnation and freesias in spring: roses and gypsophila paniculate in summer : chrysanthermum in autumn : gypsophila paniculate, roses chrysanthemums and lilies in winter. 2. The uses of cut flowers was mostly for gifts(58.4%), and that of pot flowers was mostly for home decoration. 3. flower shops were the most popular place for buying cut flowers(59.5%), followed by wholesale markets(22.5%) and street stalls(16.2%). In the case of pot flower, wholesale markets were the most favorite place(32.4%), street stalls(27.9%), flower shops(24.8%), and farm houses(11.9%). The survey showed that consumers frequent a shopping place because of 'easy accessibility', and 'various varieties in stock' in the case of cut flowers and, in that of pot flowers, 'easy accessibility' and 'low price' were the main resons in the case of pot flowers. 4. The purchase frequency rate by seson for cut flowers was that 'regardless of season' was 58.1% and 'spring', 28.9%. For pot flowers, 'spring' 58.9% and 'regardless of season' 33.6%. For the day of the week cut flowers were bought most open, Saturday came first with 34.2%, Monday and Sunday followed with 27.0% and 15.5% respectively. On the other hand, Sunday came first with 42.3%, Saturday(32.5%) and Monday(8.3%) took the second and third place respectively for pot flowers When it came to the purchase time of the day for cut flowers, 31.8% of the respondents bought then between ten and noon and 21.8% between four and six in the afternoon. 5. concerning the average amount of money spent at one time for cut flowers, 33.3% of the respondents said 3,000won to 5,000won and 23.2% replied 5,000won to 10,000won. While 36.8% answered that they paid 5,000won to 10,000won and 23.5% said 3,000won to 5,000won for a pot flowers. 6. Relating to the demand of flower stores, 28.8% wanted 'low price' : 27.9%. requested 'clear markings of the prices' : and 26.4%, wanted 'abundant commodities'

Laparoendoscopic single-site surgery (LESS) is helpful if not an evidence of suspicious malignancy in huge adnexa tumors. This approach might be reasonable alternative to conventional laparoscopic surgery. We report two cases with LESS for huge cystic adnexal tumors in whole abdomen. A 58 years old multigravida woman in menopause underwent removal of a huge cystic adnexal mass that occupied her entire abdomen by LESS.(ca.5200ml aspiration) A 15 years old single nulligravida woman had a huge cystic adnexal tumor in whole abdomen reaching to the level of the xyphoid process. A needle through the transumbilical single port was inserted directly under the mass. Subsequently, 8000 ml of cystic fluid was aspirated without spillage.

Objectives : To estimate the economic burden of osteoporotic vertebral fracture (VF) from a societal perspective. Methods : From 2002 to 2004, we identified all National Health Insurance claims records for women ${\geq}50$ years old with a diagnosis of VF. The first 6-months was defined as a "clearance period," such that patients were considered as incident cases if their first claim of fracture was recorded after June 30, 2002. We only included patients with ${\geq}$ one claim of a diagnosis of, or prescription for, osteoporosis over 3 years. For each patient, we cumulated the claims amount for the first visit and for the follow-up treatments for 1 year. The hospital charge data from 4 hospitals were investigated to measure the proportion of the non-covered services. Face-to-face interviews were conducted with 106 patients from the 4 study sites to measure the out-of-pocket spending outside of hospitals. Results : During 2.5 years, 131,453 VF patients were identified. The patients had an average of 3.38 visits, 0.40 admissions and 6.36 inpatient days. The per capita cost was 1,909,690 Won: 71.5% for direct medical costs, 20.6% for direct non-medical costs and 7.9% for indirect costs. The per capita cost increased with increasing age: 1,848,078 Won for those aged 50-64, 2,084,846 Won for 65-74, 2,129,530 Won for 75-84and 2,121,492 Won for those above 84. Conclusions : Exploring the economic burden of osteoporotic VF is expected to motivate to adopt effective treatment options for osteoporosis in order to prevent the incidence of fracture and the consequent costs.

崔圭晧,裵相源 全北大學校 1993 論文集 Vol.35 No.-

The purpose of this paper is to examine the problems which a Fruit and Vegetables wholesalemarket has in the early days of its operation by surveying the problems that the wholesalemarket opened in Kwang-ju in February 1991 has since the opening, thereby to seek the measures to improve them. The results of analysis are as follows ; 1. The market is not capable of dealing to due amount of handling from the beginning of its opening, because the scale of the market is not big enough at the point of its opening. 2. The market only deal in fruit and vegetables ; no fisheries are handled. 3. Marketing facilities of the market is improper and insufficient. 4. The dealing amount that the vegetable jobbers handle is so small that some of them are also engaged in gathering by consigment purchase. 5. They need to be educated in the field of marketing and practical affairs. If the problems brought up are to be improved, wholesalemarkets built under a public project will do much for the improvement of agricultural marketing.

In order to investigate antitumor activities of the extracted polysaccharides from Phellodendron chinense SCHNEID, the following studies were carried out. Phellodendron chinense SCHNEID was extracted with hot water and alkali, and the extracted polysaccharides showed antitumor activities against mice Sarcoma-180 solid tumors in parameters of tumor weight, inhibition ratio, thymidilate synthetase(TS) and thymidine kinase(TK) activities. The results were as follows : 1. Delipidated extracts from Phellodendron chinense SCHNEID, were systematically fractionated, the heteropolysaccharide contains D-N-acetylglucosamine, D-galactose, D-mannose, D-glucose. The molecular weight distribution of the sample was found to be nearly homogeneous (about from 200 to 1000 kDa) in gel permeation analysis. 2. Among the polysaccharide fractions, the water extracted fractions, particularly Fr.-2, showed a potent growth-inhibitory activity against implanted in mice Sarcoma 180 solid tumor (inhibition, 95.3%, at 2 ㎎/100g), but the cold alkali extract (Fr.-4) showed a very low activity (inhibition; 4.7%). Fr.-7 and Fr.-8 showed the highest tumor inhibitory activity (inhibition; 96.4 and 98.2%, respectively). 3. TS activity in the Fr.-2 given oral administration of propolis was markedly suppresed to 73.7% of that in the control (p<0.01 by Student's t-test). However, there was little difference in TK activity with a slight decrease in Fr.-2 only.

To evaluate appropriate diagnostic studies for renal infartion in emergency medical center, we analysed 33 patients of renal infarction treated in this hospital for last 8 years. Eleven patients, 4 trauma associated and 7 aortic disease associated patients were excluded. They are 11 males and 11 females with a mean age of 51 years. Fourteen came to the emergency medical center and seven came to the outpatient department, in the other one patient renal infarction was developed during hospitalization with other disease. On their past history they had hypertension in 9, valvular heart disease in 5, and diabetic mellitus in 4 patients. Abdominal or flank pain was noted in 17 of 22(77%). The other symptoms were vomiting, nausea, fever and so on. On microscopic examination of initial urine in hospital, 5 patients showed more than 10 red blood cells by high power field examination. The mean lactic dehydrogenase level was 1,239 I.U/L(normal range 218-472 I.U/L), while the mean aspartate aminotransferase and mean alanine aminotransferase were 51 I.U/L(normal range 13-36 I.U/L) and 44 I.U/L(normal range 5-33 I.U/L). Abdominal ultrasonography showed positive findings in 5 of 16(31%), of which 3 were confirmed by Doppler ultrasonography. In 18, computed tomography was done and all those showed positive findings of renal infarction(100%). In conclusion, it is important that identify the elevated lactic dehdrogenase level in case of any suspicion about renal infarction and confirm by computed tomography.

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.
