Background : For cultivation of varieties of ginseng, the pure line selection method, which is to select the best among those cultivated in farms for pedigree breeding, replicated yield trials and regional adaptation trials before registering as a new variety, is widely used. Although there are 25 registered varieties of ginseng in Korea, the quality of ginseng is declining together with the amount of harvest being decreased by 15 - 20% due to the heat injuries and diseases from the warming & abnormal climate. Thus, the needs for development of disaster-resistant varieties with better chances of surviving through high temperature, salts and disease are increasing. Therefore, this study is to cultivate disaster-resistant varieties among those selected for their disaster tolerance and salt tolerance through regional adaptation trials. Methods and Results : As a result of examining the growth characteristics of the selected 2 - 5 year old varieties used in the study, among the 5-year old crops, Goryeo 4 and Eumseong 5 showed superior growth in both above and below aerial parts, and among the 4-year old crops, Eumseong 11 and Cheonryang showed superior growth while the growth in the below aerial parts were satisfactory in the order of Cheonryang > Eumseong 10 > Eumseong 11 > Eumseong 9. Among the 3-year old crops, the most superior growth in both above and below aerial parts was observed in Eumseong 14 with the weight of the below aerial part, root diameter and taproot length at 13.8 g, 11.8 ㎝ and 6.2 ㎝ respectively. Among the 2-year old crops, Eumseong 10 showed the most superior growth in both above and below aerial parts. Conclusion : Based on the above results, Goryeo 4 and Eumseong 5 among the 5-year old crops, Eumseong 11 among the 4-year old crops, Eumseong 14 among the 3-year old crops and Eumseon 10 among the 2-year old crops showed the most superior growth among the selected varieties. The growth characteristics of both above and below aerial parts in each year will continuously be monitored.

This study was done in order to investigate the effect of choˇkda~m-t'ang on hyperlipidemia. Methods: Hyperlipidemia was induced in male rats by oral administration of cholesterol(50㎎/㎏) diet for 45 days. To carry out an experiment, the rats was divided into three groups. The first group(normal group) was fed on water for 45 days. The second group(control group) was administered 5% ethanol instead of water only for first 15 days and subsequently administered cholesterol(50㎎/㎏ p.o) diet with 5% ethanol for the second 15 days and fed on a solution of salt for the last 15 days during total 45 days. The third group(sample group) was administered in the same way with the control group for 30 days and injected choˇkda~m-t'ang extract(100㎎/㎏) for the last 15 days during total 45 days. And measured the levels of serum total cholesterol, serum HDL-cholesterol, serum total lipid, serum triglyceride, serum phospholipid, hepatic lipid peroxide and activity of serum AST·ALT. Results: 1. From fifteenth day, the level of total cholesterol was decreased with the significance in the sample group as compared with the control group. 2. The level of serum HDL-cholesterol was increased in the sample group compared with control group, but did not show significance. 3. The level of serum total lipid was decreased with significance in the sample group as compared with control group. 4. The level of serum triglyceride was decreased with significance in the sample group as compared with control group. 5. The level of serum phospholipid was decreased in the sample group compared with control group, but did not show significance. 6. The level of hepatic lipid peroxide was decreased with significance in the sample group as compared with control group. 7. The activity of serum ALT was decreased with significance in sample group as compared with control group, but that of serum AST was not significance. Conclusion According to above results, it is considered that choˇkda~m-t'ang injection groups have recovering effect on the hyperlipidemia induced by oral cholesterol administration in male rats. This might be suggest that choˇkda~m-t'ang have recovering effect on arteriosclerosis and cerebral vascular accidents.

Properties analyses and treatment characteristics of waste slurry discharged in the wetted flue gas desulfurization process using Mg(OH)₂as a absorbent were investigated. Aeration and coagulation test were carried out to evaluate variation of some factors such as COD, SS, T-N, etc. related to waste slurry treatment. The hydraulic retention time(HRT) and coagulant dosage rate were applied as operating variables in experiment. As experimental results, the reduction effects of COD, SS in aeration test were distinct, due to oxidation of SO₃ and floc, formation of suspended solids. It was also found that the reduction efficiencies of SS and T-P in coagulation test are higher than 90%.

김영근,김수경,안기홍 한밭대학교 정보통신전문대학원 2005 정보통신전문대학원 논문집 Vol.3 No.1

정보통신의 발전은 경제 구조에 많은 변화를 가져왔으며, 향후에도 많은 변화를 예고하고 있다. 가장 대표적인 것은 경제 흐름의 근간이라 할 수 있는 유통의 변화이다. 이것은 통신망 위에 구축되는 가상의 공간에서 이루어지는 유통을 지칭하는 것으로, 빠른 속도로 발전하고 있다. 이러한 빠른 발전에도 상품데이터베이스를 구성하는 것에는 매우 불합리한 비효율성이 존재한다. 상품데이터베이스 구성의 가장 큰 비효율은 싸이트들이 개별의 데이터베이스를 구성한다는 것이다. 이런 문제를 해결하기 위해 시멘틱웹의 RDF(Resource Description Framework)언어를 이용하여 웹 온톨로지를 구성하여 공급자와 판매자간 상품 데이터를 공유하게 된다면, 전자상거래에서 상품데이터베이스 구성의 비효율성을 제거 할 수 있다. 따라서 본 논문에서는 RDF의 소개와 RDF 웹 온톨로지 편집기를 제작하고, 구성된 RDF를 참조하여 간단한 쇼핑몰을 구성하여 온톨로지를 통한 데이터의 효율적 상호운영성(Interoperability)을 증명하여, 현재 제안되고 있는 상품 카탈로그 분야의 발전에 기여하고자 한다. IT development has brought about many changes in an economic structure, and will bring about many changes in the future. The most representative thing is the change of distribution which is a basis of the economic flow. It means a distribution an a virtual space built through communication network. It has rapidly developed. However, building the product database by each site for numberless products is very unreasonable simple repeating process. To solve this problem, if the product data is shared between a supplier and seller through the web ontology by using the Semantic Web RDF (Resource Description Framework) language, an efficiency of e-commerce will be created. Accordingly, the study is intended to prove an efficient interoperability of data through ontology by introducing the RDF, fabricating the RDF web ontology editor, and building a simple shopping mall through organized RDF, and to contribute to a development of currently-proposed product catalog field.

Anchorage plays an important role in orthodontic treatment, Skeletal anchorage like the miniscrew is considered a more effective method in anchorage control than conventional anchorage which needs much patient s cooperation. The miniscrew offers many advantages. 1) It is easy to insert and to remove. 2) It can endure the force needed for moving teeth. 3) It can be immediately loaded and 4) Patient cooperation is not needed. 5) It is economic compared to other skeletal anchorage systems, In comparison to adult's bones, children s bones have comparatively poor bone quality and quantity. Therefore, it is hard to obtain primary stability in younger patients. However, if the miniscrew can be retained successfully, it will be effective in many orthodontic treatments. In these cases we used the miniscrew in correcting of diastema, in aligning dental midline, and in rendering a forced eruption of impacted tooth in mixed dentition patient. We obtained satisfactory results. 교정치료 시 고정원은 항상 염두에 두면서 치료를 진행해야 하는 중요한 요소이다. 전통적인 고정원을 이용한 치료는 환자의 적극적인 협조를 필요로 하고 원하는 치아이동에 대한 반작용이 나타날 수 있는 등의 부작용을 가지고 있다. 그러므로 보다 견고한 구강 내 고정원이 요구되어져 왔으며 이를 위해 miniscrew가 임상에서 흔히 이용되고 있다. Miniscrew를 통한 고정원의 확보는 구외력 의존도 감소,치료기간의 단축,식립 후 즉시 교정력 적용,환자의 협조도 불필요,식립의 간편성,저렴한 비용 등의 장점을 가지고 있다. 그러나 성장기 환자는 성인에 비해 골질이 좋지 않아 miniscrew의 성공률이 성인에 비해 낮다. 그러나 일단 고정에 성공하면 많은 교정치료 시 매우 유용하게 이용할 수 있다. 본 증례는 흔합치열기 환자를 miniscrew를 이용하여 정중이개 및 정중선 불일치,매복치에 대한 양호한 교정치료를 하였기에 보고하는 바이다.

저자들은 임상과 혈액검사에서 CMV monoucleosis로 진단된 21세 남자환자에서 골수검사상 적혈구를 탐식하는 조직구의 증식으로 보아 CMV가 그 원인으로 추정되는 IAHS 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. The 21-year-old male patient complained of high fever, chills, severe malaise, myalgia, and gingival bleeding for 10 days. The patient presented pancytopenia and hepatosplenomegaly. We examined peripheral blood smear, bone marrow aspiration and biopsy, serologic tests for antibodies on cytomegalovirus(CMV), platelet and heterophil, and upper abdominal ultrasonography. There were pancytiopenia and peripheral lymphocytosis with atypical lymphocytes in the peripheral blood smear and histocytes phagocytosing red blood cells in the bone marrow examination. The CMV-specific IgM antibody was positive. The antibodies for platelet and heterophil were absent. We diagnosed as Infection-Associated Hemophagocytic Syndrome (IAHS) due to CMV for the patient. Therefore, we report a case of IAHS associated with CMV mononucleosis with a brief review of literature.

Background : Recently, the lung cancer mortality rank first in Korea. The prognosis of lung cancer is not good enough with current treatments and multimodality treatments are required. So we are interested in the characteristics of lung cancer patients for better treatment. Methods : We searched lung cancer patients since 1994. Then we collected the data of primary lung cancer patients about the demographic features, histologic types and diagnotic methods. We divided the total period into 2 haves and specific analysis was tried. Results : 1) Total 850 patients were included. 633 (74.5%) were male and 217 (25.5%) were female. 2) The mean age was 65 ± 11 years old. and the peak age was 7th decades. 3) Squamous cell carcinoma(334/850, 39.3%) was slightly more prevalent than adenocarcinoma(302/850, 35.5%). Conclusion : From these results, we expected that older persons will be diagnosed to have lung cancer and adenocarcinoma will be more dominant histologic type with time.

The Bi₂Sr₂CaCu₂O_(8)+_(δ) single crystals are grown from the melt using a stoichiometric starting composition fer the cautions. The size and thickness of the Bi₂Sr₂CaCu₂O_(8)+_(δ) crystals depends on the cooling rate. The lower the cooling rate, the bigger and thicker the Bi₂Sr₂CaCu₂O_(8)+_(δ) crystals become. Bi₂Sr₂CaCu₂O_(8)+_(δ) X-ray diffraction(XRD) measurements of the single crystals were carried out using the radiation source of Cu Kα . In these Patterns only the (0,0,2n) diffraction appeared. The result indicated that the cleared surface of the single crystal was of the a-b face, and that the single crystal had a single phase without any undergrowth with 7K and 85K phases. In addition, although the figure is not shown, XRD patterns from (006) to (00□) were observed in the range of 2θ=0 to 60 degrees. The characterization of as-grown single crystals have been analyzed by Laue X-ray backsdattering along the c-axis and X-ray precession experiments. The result of magnetic moment vs Tc in 10 Gauss for a crystals were measurements indicated that the samples have a superconducting transition temperature of 85K.
