연구목적 : 지금까지 난치성을 보이는 사마귀의 치료로 Bleomycin 행변내 주사의 효과가 많은 연구에서 보고된 바 있다. 이에 저자들은 본 치료방법의 효과를 사마귀의 크기, 숫자, 위치 및 유병기간에 따라 판정하여 보다 효과적인 적응 대상을 알아보고자 했다. 방법 : 1995년 3월부터 1998년 2월까지 이화여자대학교 목동병원 피부과에 비성기성 사마귀로 내원한 환자중 다른 치료에 반응하지 않았거나, 재발한 경우, 크기가 0.5㎝ 이상이거나 7개 이상의 다발성 병변 , 혹은 조감 주위 병변을 보인 133명의 환자를 대상으로 Bleomycin 병변내 주사로 치료하였다. 1회 치료후 효과와 치료 종결후 완치율을 병변은 크기, 숫자, 위치, 유병기간에 따라 비교하였다. 결과 : 1) 환자의 연령 분포는 4세에서 45세였고, 남자 59명 여자 74명으로 1:1.24 비율이었다. 2) 첫 주사 치료후 96명의 환자에서 50% 이상의 병변의 수나 크기의 감소를 보였다. 크기별로는 0.5~0.9㎝의 87.5%에서, 병소의 수별로는 단일 병소의 76.9%에서 50% 이상의 병변의 크기나 수의 감소를 보여 가장 좋은 효과를 보였으나 통계적 유의성은 없었다. 또한 조갑주의 병변은 79.1%에서, 수부는 75.8%, 족부는 72.9%에서 50% 이상의 호전을 보였으나 족서부 병변은 53.4%로 가장 낮은 낮은 효과를 보였다. 유행병 기간은 6개월 이하인 31명(86.2%)에서 50% 이상의 효과를 보여 유병기간이 짧을수록 치료효과가 유의하게 증가하였다(p<0.05) 3) 치료 종결시 3개월 이후까지 재발없이 완치된 경우는 총 93명으로 69.9%였고 치료받은 병변의 수가 증가할 수록 완치율이 감소하였다, 부위별로는 조감주위가 77.1%로 가장 높았으며, 병변의 크기에 따른 일괄된 완치율의 차이는 없었다. 병변의 기간에 따른 완치율은 6개월 이하에서 80.6%로 가장 높았으며, 유병기간이 길수록 완치율은 감소하는 양상을 보였다. 4) 부작용은 환자 중 18.4%인 24명의 환자에서 발생하였으며, 유형별로는 3일 이상 지속된 동통과 홍반, 색소 침착 및 감염이 관찰되었으나, 모두 이후 호전되었으며, 1명에서 경한 조갑 능선을 동반한 변형이 관찰되었다. 결론 : 본 연구에서 사마귀에 대한 Bleomycin 병변내 주사효과가 병변의 크기에 따라 뚜렷한 차이를 보이지 않았으며, 심한 부작용이나 전신적인 독작용없이 조감주위병변 및 급성기 병변에서 높은 완치율을 보여 좋은 적응증이 됨을 확인하였다. 아울러 Bleomycin 병변내 주사의 효과 및 안정성에 있어서 시술자가 적당한 양의 약물을 주변부위로 부터 과도한 침습없이 정확히 병변의 기저부에 도달시키는 기술이 또하나의 중요한 변수가 됨을 반영하는 결과라 사료된다. Purpose:This study was to designed to evaluate the efficacy of intralesional injection of bleomycin for common warts and plantar warts according to size, number, location, and duration and to determine the appropriate indication of this treatment for warts. Materials & Methods : The objective patients had warts being refractory to previous treatment or large than 0.5cm in size or 7 or more lesions or periungal lesions. The intralesional injection with bleomycin hydrochloride 1㎎/㎖ had been performed single to six times at 3 week interval until complete resolution. Age of the patients ranged from 4 to 45 years, and male to female ratio was 1 : 1.25(59 : 74). Results : After first treatment of bleomycin intralesional injection, a reduction of 50% or more of the primary wart area was observed in 96(72.2%) of 133 patients. 93(69.9%) of 133 treated patients experienced complete cure after 1 to 7 injections. The efficacy of intralesional bleomycin injection for warts was not closely associated with the size of warts. However the duration and number of warts was inversely correlated with the efficacy of treatment. The highest cure rate was shown in patients with periungal warts(77.1%), and lowest in patients with plantar warts(53.3%). The side effects were observed in 18.4%(24 of 133) including persistent pain(17.3%), pigmentation(3.0%), erythema(1.5%), and mild nail dystrophy(0.8%), but no evidence of systemic toxicity was found. Conclusions : The efficacy of intralesional injection of bleomycin was not significantly related to the size, but closely related to the duration, number and site of the lesion. These results partly suggest that there is some important factors affecting the efficacy of treatment of bleomycin such as duration of the lesion and skillful injection of the agent into the wart tissue.

This paper is a research on the coefficient of friction occured between the channel and concrete through a push-out testing. For preparing the test pieces, the authors meaured the size of a concrete slab according to the specification of the composite girder design, using the high tension bolts instead of various dowels for shear connector. The result showed the possibility to design composite girder under the condition of the coefficient of friction μ=0.38 using the high tension bolts.

Zn_0.4Cd_0.6Te : Li의 p형 단결정을 Bridgman법으로 성장시키고, 이결정들의 전기적 및 광학적 특성을 조사하였다. 또 이 결정에 Al을 확산시켜 Zn_0.4Cd_0.6Te : Li-Al의 p-n 동성집합 LED을 제작하였고, 이 LED의 특성, 즉 I-V, EL spectrum 및 발광강도의 전류의존성 등을 조사하여 발광천이 관계를 추정하였다. 또 모체결정의 열처리에 따른 발광특성의 변화도 아울러 조사하였고 끝으로 이들의 에너지밴드 모형과 발광천이 관계를 추정하였다. The pure and Li doped Zn_0.4Cd_0.6Te single srystals were grown by Bridgman method respectively, and the their electro-optical properties were investigated by transmission, photoluminescence and Hall effect mesurements. Through carring out the Al vapor-diffusion into the Li doped Zn_0.4Cd_0.6Te crystals in thermal process, the p-n homojunction LEDs, Zn_0.4Cd_0.6Te:Li-Al, were fabricated. The characteristics of LEDs were investigated by measuring the current-voltage, the electroluminescence spectra and emitting light intensity. And also, the characteristics of LEDs prepared with various thermal anealing were compared with each other. Finally, the energy band model were estimated, and the light emitting mechanism was presumed.

Individual identification is an important part in medicolegal field especially in mass disaster. At July, 27, 1989, KAL KE-803 was crashed on landing at Tripoli International Airport, Liba. The plane was caught in fire and sixty eight Koreans were sacrified. The majority of victims were severely charred and injured. The authors examed all dead bodies and successfully identified all the cases through visual, anthropological, odontological, radiological and pathological methods including fingerprint and blood typing.

Individual identification of severely decomposed or skeletonized bodies is an important part in medicolegal field. 142 bodies were torn up and carried away by flood in a park cemetry, Kwang-Ju, Kyunggi province, Korea at Sept., 10, 1990. The authors examed the 56 bodies, which were gained, through medical, anthropological, odontological, radiological methods, and superimposition for individual identification. Among them, 41 cases were successfully identified, and remaining 15 cases were not identified because of sever destruction and no adequate information.

슬럼프값을 갖지 않는 콘크리트에 관한 연구

鄭海駿,姜準默,李鎭沃 충남대학교 공업교육연구소 1982 論文集 Vol.5 No.1

This paper identified the W/C ratio of no-slump dr lean concrete analyses its compressive strength and its coefficient of permeability. The relation between no-slump W/C ratio and the quantity of unit cement is approximately linear. The compressive strength by variation of W/C was relatively low and the coefficient of permeability was comparatively high. By the use of admixture, a better quality of no-slump dry lean concrete is expected.

鄭海駿,姜準默 충남대학교 공업기술개발연구소 1975 工業技術開發硏究所論文集 Vol.2 No.2

Todays the range that concrete material occupies of all the constructive materials is larger than any other material. Concrete material occupying the major part as all the constructive materials has a lot of merits, but the greatest defect is that tensile strength is low to compressive strength as we can disregard its values in engineering. Therefore concrete needs a certain material reinforcing this. As reinforce, we have reinforced the defect of concrete by inserting metal rinforcement in it. In this study, thinking a great many wire pieces can be produced, dynamic character is excellent, and construction method is easy, the authors used wire pieces as a mixture to reinforce concrete. This experimental result is to present a practical possibility.

We report an annular type of subacute cutaneous lupus erythematosus(SCLE) which is rare in Korea, A 23-year-old female had erythematous annular rashes with a mild itching sensation on the face, trunk and both extremities. She also had painless oral mucosal ulceration, diffuse hair loss and mild arthralgia. Serologic abnormalities of the patient were positive anti-Ro Ab, ANA and Anti-ds-DNA Ab. The histopathologic findings showed vacuolar degenerations in the basal cell layer, mononuclear cell infiltrate in the upper dermis, and dermal edema. Direct IF revealed granular deposition of IgG and IgA at the dermo-epidennal junction.
