A new sesame variety Kangbaek was developed from Yeongnam Agricultural Research Institute in 2004. Cros wasmade by lodging resistant SP9003-3 line to the F1with high yielding capacity, folowed by pedigree selection, yield test and RYT by the sesame breeding team at the National Insti-tute of Crop Science up to 2003. The variety showed higher disease resistance, especially phytophothra disease, and lodging resis-respectively. It's 1000 grains weight was about 2.54 g indicating 0.03 g heavier than that of Yangbaekkae, and it's oil content wasabout 52%. Kangbaek also contained total 7.65mg/g of such lignans as sesamin and sesamolin. The average yield of Kang-baek was 82 kg per 10a at the national-wide regional performance.

Objective : Hemophilia, a genetically determined disorder, is characterized by abnormality of the coagulation mechanism due to functional deficiency of a specific factor, namely VIII or IX. In this study, the effect of Dong-Si acupuncture therapy on the cerebral hemorrhage patient with hemophilia was evaluated. Methods : We treated him with acupuncture by stimulating Dong-Si acupuncture point(Yuk Wan) and assessed the effect by using manual dynamic evaluation of MRC(Medical Research Council) and Modified Barthel Index. Results : After treatment, the bleeding tendency was grossly reduced and bleeding lesion was absorbed gradually. And manual dynamic evaluation of the upper extremity increased from 4 grade to 5 grade. Conclusions : This result suggest that Dong-Si acupuncture therapy on the cerebral hemorrhage patient with hemophilia was effective. And futher studies are required to concretely prove the effectiveness of Dong-Si acupuncture therapy for treating hemorrhagic diseases.

연골육종은 비교적 서서히 자라며 늦게 전이하는 악성 연골 종양으로 알려져 있다. 골 연골종에서 발생한 속발성 연골육종은 발생빈도는 드물며 타부위로의 전이가 적고 악성도가 낮은 경우가 많아 적합한 수술적 치료로서 좋은 예후를 보이는 것으로 보고되고 있다. 본 동국대학교 정형외과학 교실에서는 우측 대퇴골 원위부 골간단부에 생긴 고립성 골 연골종에서 이차적으로 발생한 연골육종을 치험한 바 문헌고찰과 함께 보고하는 바이다. A case of Secondary Chondrosarcoma Arising from Solitary Osteochondroma of the Distal Femur Department of Orthopaedic Surgery, College of Medicine, DongGuk University Phil Hyun Chung M.D., Jung Su Hwang M.D., Suk Kang M.D., Yang Mln Kim M.D., Hyung Ho Oh M.D., Dong Ju Chae M.D., Jong Pil Kim M.D. Chondrpsarcoma is a malignant cartilage-forming tumor that grows slowly and metastasis of this tumor occurs in late stage. Secondary chondrosarcomas arising from a solitary osteocartilaginous exostosis are rare and those have a better prognosis than other chondrosarcomas, and they rarely metastasize. We present our experience with a case of secondary chondrpsarcoma arising in solitary osteochondroma of distal metaphysis of right femur with clinical details.

출발물질로 D-타타르산 사용하여 (+)-eldanolide의 합성을 연구하였다. 이 합성에서의 중요반응은 온도를 -78℃→0℃로 하여 lithium diisopropylamide 사용하여 (2R, 3R)-1-chloro-2,3-isopropylidenedioxy-6-methy-5-heptene을 탈수소-제거반응시켜 중요한 반응 중간체인 (3R)-6-methyl-heptyn-5-en-3-ol을 합성하는 것이다. Synthetic approach to (+)-eldanolide from D-tartaric acid as starting material is described. They key reaction is the deprotonation-elemination reaction of (2R, 3R)-1-chloro-2, 3-isopropylidenedioxy-6-methyl-5-heptene with lithium diisopropylamide at -78℃→℃ and the key intermediate is (3R)-6-methyl-heptyn-5-en-3-ol.

The effects of Laminaria japonica fucoidan extract (LJFE) on the biochemical parameters of lipid-related function were investigated in liver and serum of CCl_(4)-treated rats. LJFE of 100 mg/kg concentration was intraperitoneally administered into rats at dose of 1.5 ml/kg for 14 days. On the day 15, 3.3 ml/kg of CCl_(4) dissolved in olive oil (1:1) was injected 12 hours before anesthetization. We examined the lipid-related functions and enzyme activitys by measuring the levels of total cholesterol (TC), triglyceride (TG), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) in serum. The results showed that CCl_(4) treatment increased the high values of TG, LDH and ALP decreased the low values of TC but LJFE pretreatment decreased the high values of TG, LDH and ALP to the low values, increased the TC. It was suggested that LJFE can be used as the potential candidate for the lipid-metabolism natural supplement.

Mechanical vibration modes of the vibrating screen affect the fractional separation efficiency of any given screens which are used to classify the sizes or shapes of particulate matters concerned. Even though there are many parameters influencing on the performance of the given screen separators, in this study, the effective vibration speeds of the screen are selected as the main variable in the screening separation of particulate matters. The sample materials are glass beads in the particle size range of 100 to 900㎛. The cut size opening of the test screen is 600 ㎛. The other operating variables of the vibrating screen used are fixed. Fractional separation (Grade) efficiency curve(i.e., classifier selectivity curve) will be drawn to compare the effect of vibration speed of the inclined vibrating screen. And also the model of the probabilistic approach proposed by other investigator(subashinghe) will be tested on the screening data observed in this work.
