This study was conducted to develop a simple selection method for herbicide-resistance weeds. Two methods, designated "seedling method" and "stem node method" were employed for screening of barnyardgrass against propanil and butachlor. In the seedling method, shoot and root growth of barnyardgrass were significantly inhibited at quarter of the recommended herbicide rate, while in the stem node method, the similar inhibition was obtained at half of the recommended rate. Thus, it was concluded that the seedling method is more simple and quick method to evaluate response of barnyardgrass to propanil and butachlor compared to stem node method.

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.

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.

Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherapy seems a logical choice for cancer chemotherapy. In this study, Mitomycin C (MMC)-activated charcoal (CH)-alginate (ALG) beads were prepared by the mixtures of CH particles adsorbed with MMC as an anti-cancer drug and aqueous alginate solution. The alginate is recognized as biodegradable, nontoxic, and biocompatible. The release of MMC from the beads in 0.1 M Tris buffer was stable and continuous until about 1 week. The MMC-CH-ALG beads can be applied in the peritoneal cavity for intraperitoneal chemotherapy since they provide a good adhesiveness on the tissue and controlled release pattern of the drugs.

Sludge treatment has been studied with many researcher since disposal problem of sewage sludge was became powerfully. But there was still the problem of secondary pollution and heavy metal leaching in the sewage sludge treatment process. To solve the problem, the treatment was to produce active carbon through the carbonization and the steam activation. In this study attempts to optimum design a activated carbonizer and optimum operation conditions and the technology as changing the variables. parametric screening studies were carried out for variations of the following variables : input of steam "10∼80 g/min" and carbonized time "12∼31.2 min". At the result of this is chosen, that input of steam "35 g/min" and carbonized time "31.2 min". At this time, Iodine adsorptivity and output particle diameter shown that 245.5 ㎎/g and under 4 mm. And also, by using photograph and SEM were confirmed the pore development.

Neonatal lupus is a rare syndrome occurring In neonates with tranplacentally acquired maternal autoantibodies, In particular anti-SSA/Ro-SSB/Ra antibodies. Manifestations include congenital heart block, cutaneous lesions, thrombocytopenia, neutropenia, pulmonary or neurological disease and hepatitis. The non-cardiac manifestations resolve by 6 months of age, congenital heart block is irreversible. We experienced a case of neonatal lupus with congenital complete heart block in a newborn of asyptomatic mother with anti-SSA/Ro-SSB/Ra antibodies.

Bacteriocins are natural antimicrobial compounds produced by many microorganims associated with foods, so that there is currently much interest in their use as food biopreservatives. Goal of this study were to identify bacteriocin-rpoducing strain and to produce the bacteriocin in jar fermenter. Lactic acid bacteria JW3 was tentatiely identified as Lactococcus lactis by the use API 50 CHL kit. Therefore, lacticin JW3 is proposed as the tentative name of the bacteriocin produced by Lactococcus lactis JW3. Lactitin JW3 production in jar fermenter was reached the maximum at the early stationary phase, but decreased after the stationary phase. The bacteriocin showed typical primary metabolite kinetics.

Finite element method is very effective method to simulate the forming Processes with good prediction of the deformation behaviour. For the finite element modeling of sheet mental forming the accurate tool model is required. Due to the geometrical complexity of real-size Part stamping tools it is hard to make FE model for real-size auto-body stamping parts. In this paper, it was focussed on the drawability factors on auto-body panel stamping by AUTOFORM with using tool planing alloy to reduce law price as well as high precision from Design Optimization of die. According to this study. the results of simulation will give engineers good information to access the Design Optimization of die.
