We described three cases of immediate reimplantation of a frozen-thawed autogenous mandible composed of a mixture of iliac bone, marrow, and particulate hydroxyapatite in tumors of the mandible. Acceptable outcomes were obtained in three patients who underwent immediate autogenous mandibular graft reconstruction. The conditions leading to successful outcome of the procedure are also discussed. Reimplantation of frozen autogenous lesioned mandible was performed in three patients with mandibular tumors. Two reimplanted grafts survived without complications following surgery. One case had postoperative infection that resolved with appropriate antibiotic treatment. There were no recurrences of the primary lesions. Satisfactory facial contour after surgery was achieved. These results are most promising, and we believe that, with further refinement, this technique will offer a new and acceptable modality for facial reconstruction in patients with cancer.

정보통신망의 급격한 발전으로 더욱더 정확하고 빠른 정보통신시스템이 그 어느 때보다 요구되나 통신망에 존재하는 여러 가지 소음 등으로 양질의 정보를 취득, 전송하는 것이 쉽지 않다. 본 논문에서는 dSPACE DS 1103보드와 적응소음제거(ANC) 알고리즘으로 여러 가지 소음 중 가장 일반적인 백색잡음에 오염된 음성신호로부터 원래의 깨끗한 음성신호를 실시간적으로 추출하려고 한다. 결과적으로 DS 1103보드의 실시간 처리 구현의 편리함은 탁월하게 보여졌으나, NLMS 알고리즘의 계산속도의 한계로 정확하게 소음이 제거된 원래의 음성신호 파형을 얻을 수 없었지만 어느 정도 음성의 내용을 인지 할 수 있는 수준의 신호 파형을 얻을 수 있었다. Because of the extremely fasts growing expansion of the information communication networks, the more accurate and fast information transfer between communication systems is required more than ever. It is desired to denoise in the networks to transfer and store the good qualify information. In this paper, dSPACE DS 1103 real-time DSP board is used to denoise the white noise which contaminate the original speech signal with the Adaptive Noise Cancellation (ANC) algorithm. As a results, dSPACE board is a very powerful device for the noise reduction, because of the easy processing, simple manipulation and fast implementation of the ANC system. The simulation result also give us a significant noise reduction from the contaminated speech signal with the real-time processing.

농도와 기간에 따른 바이러스 감염 및 항바이러스제인 amantadine병행 첨가 시 Maddin-Darby canine kidney (MDCK) 세포 내의 free radical 해독계 효소인 glutathione S-transferase (GST)와 lactate dehydrogenase (LDH)의 활성 변동을 상호비교 관찰하였다. 바이러스에 감염된 MDCK 세포는 감염 3일 후 1 TCID50군은 80% 이상, 10 TCID50군은 거의 대부분의 단층세포가 탈락되는 병변 효과가 나타났다. Amantadine cytotoxic dose %가 증가함에 따라 MDCK 세포 내의 GST 및 LDH 활성은 농도에 따라 유의하게 감소되었고, 감염배지 내 LDH활성은 대조군 보다 유의한 증가를 보였다. 인플루엔자 바이러스 type A접종농도와 기간에 따른 MDCK세포 내의 GST및 LDH활성은 1 및 10 TCID50감염 군에서 감염 3일 후부터 유의하게 감소되었고, 감염배지 내의 LDH활성은 10배 이상 증가되었다. 인플루엔자 바이러스 type A 100 TCID50 감염과 amantadine 병행 첨가 시 GST 및 LDH 활성은 바이러스만 감염한 군 보다 MDCK세포 내에서 대조군에 비하여 감소율이 낮았고, 감염배지 중 LDH활성 역시 증가율이 낮았다. 또한 바이러스 감염 후 amantadine 90 ㎛/ml첨가 시에 세포 내와 감염배지 중에서 가장 낮은 감소와 증가를 나타냈다. This study was performed to evaluate the activities of glutathione S-transferase (GST) and lactate dehydrogenase (LDH) in Maddin-Darby canine kidney (MDCK) cells infected with virus and/or treated with amantadine. On cell morphological findings, monolayer fractions in MDCK cells infected with virus were exfolated more than 80% in 1 TCID50 group and that in 10 TCID50 were completely exfolated after 3 days during infectious process. In proportion to the dose of amantadine, activities of GST and LDH of MDCK cells were significantly decreased and those of LDH in medium fraction were more significantly increased compared with control. According to in both dose and time of virus innoculation, activities of GST and LDH in MDCK cells were significantly decreased in 1 and 10 TCID50 infected cells after 3 days. LDH activities in infectious medium were remarkably rised at 10 fold. In case of the cell line inoculated with type A 100 TCID50 and additionally treated with amantadine, the decreasing rate to the control in activities of GST and LDH was lower than that in those in case of that infected with virus only. These results suggested that virus infection and amantadine treatment may effect the activity of the detoxicating enzyme in the target cells.

The effectiveness of the fluoride ion in lowering the incidence of dental caries is of major significance to the entire field of dental health. Fluoride of public water supplies has been recognized for many years as an effective way to reduce dental caries. The purpose of this investigation was to determine the effect of several water conditioning systems on the fluoride concentration. A sampling apparatus was constructed to allow collection of water samples before and after conditioning. The apparatus connected the following types of water conditioning systems: a ceramic filter, a silver-carbon filter,an activated carbon filter, a reverse osmosis system and a ultra filter. These samples were tested by using colorimetric determination of fluoride concentration. The results were as follows, 1.The water fluoride concentration of primary school of Chungjcity was 0.793 ± 0.001ppm. 2.Fluoride concentrations after conditioning were 0.183 ±0.016ppm(the reverse osmosis system), 0.231 ±0.051ppm(the activated carbon filter), 0.240 ± 0.031ppm(the ceramic filter), 0.299 ±0.037ppm(the ultra filter) and 0.368 ± 0.030ppm(silvercabon filter). 3.Fluoride concentrations was reduced by the reverse osmosis system(77 ±2%), the activated carbon filter(71 ±6%), the ceramic filter(70 ±4%), the ultra filter(62 ±5%)and silver-carbon filter(54 ±4%). 4.All water conditioning systems tested caused a statistically significant reduction in fluoride(p<0.001).

Previous studies have shown that Magnoliae cortex and Ginkgo biloba extracts were showed on the antimicrobial and anti-inflammatory action, in vitro. The purpose of this study was to evaluate on the effect of antimicrobial and anti-inflammatory activity of Magnoliae cortex and Ginkgo biloba extracts containing dentifrice in gingivitis. 70 subjects with gingivitis were divided into an experimental group which performed normal oral hygiene procedure with Magnoliae cortex and Ginkgo biloba extracts containing dentifrice and a control group which also performed normal oral hygiene procedure with the same dentifrice without the natural extracts and completed a double-blind, cross-over study. At baseline and 3 weeks, subjects were assayed for clinical study by plaque index, gingival index, pocket depth, GCF rate, and microbiological study by subgingival dental plaque bacterial morphotypes by phase contrast microscopy, total anaerobes, total aerobes, Black pigmented bacteroides, A-actionomycetemcomitans, A.viscosus, C.rectus, S.sanguis, P.gingivalis, P.intermedia by bacterial culture and immunofluorescence microscopy. After 3 weeks using their respective dentifrices, reductions in the clinical indices of subjects were similar between the experimental dentifrice group and a control dentifrice group except for statistically significant much reductions in PI, GI, and GCF rate in the experimental dentifrice group as compared to control dentifrice group. Also statistically significant reductions in the motile rods and Spirochetes were found in both experimental group to compare with control group, however statistically much reduction in total anaerobes, Black pigmented bacteroides, and P.gingivalis, P.intermedia were found in the experimental dentifrice group as compared to control dentifrice group. This results indicates that Magnoliae cortex and Ginkgo biloba extracts containing dentifrice might be useful for elimination of gingival inflammation.
