In this study, The method to produce anticorrosive paint using reproductive wastepaint was investigated. The liquid-phase resin, BHO-500 and powder-phase paint BHO-300 were produced through wastepaint reproductive process. BHO-500 and BHO-300 could be replaced respectively polyvinylchloride resin and filler, which are thr components of anticorrosive paint. The properties of the anticorrosive paint produced through this process were excellent in comparison with the existing anticorrosive paint.

손운목,홍성종,이순형 인제대학교 1991 仁濟醫學 Vol.12 No.4

Metorchis orientalis의 發育 段階別 表皮 徵細構造를 주사전자현미경을 사용하여 관찰하였다. 충체가 성장 발육함에 따라 腹吸盤이 蟲澧 前方 1/3지점까지 올라와 位置하였고, 排泄孔도 충체 後端에서 腹側 前方으로 많이 올라와서 開ㅁ하였다. 배설공 주위에는 皮棘 및 感覺乳頭가 없고 多孔性의 原形質突起로 이루어진 독특한 구조의 표피가 分布하였다. 口吸盤 및 腹吸難의 口脣에는 각자 10개 및 6개의 제 Ⅱ형 감각유두가 일정한 간격으로 배열되어 있었다. 2일, 5일 및 7일된 幼苦蟲의 앞쪽 및 중간 부위 표피에는 손가락모양의 3∼6분지 피극이, 뒷쪽 부위에서는 송곳모양의 單棘이 분포하였고 2주 및 3주된 성충에서는 前, 中, 後部의 표피에 각각 9∼11分枝, 7∼10分技 밑 6∼7分技의 피극이 분포하였다. 유약충에서 자갈 모양이던 원형질돌기가 성충에서는 융단 모양이었으며 腹側面과 背側面에서 다소 配列樣相이 달랐지만 충체의 左右 外側에 1개 또는 3∼8개(grouped)의 제Ⅰ형 감각유두가 대칭적으로 배열되어 있었다. 감염 후 3주된 충체에서 표피의 破壞 및 脫落 現象이 관찰되었다. 이상의 결과로 M. orientalis의 표피는 감염후 2주까지 원형질돌기 밑 피극의 分化가 계속되고 3주 이상된 충체에서는 표피의 파괴 및 탈락이 일어남을 알 수 있었다. This study was performed to observe the tegumental ultrastructures of Metorchis orientalis according to the developmental stages. The worms were obtained from the experimentally infected chicks at 2, 5, 7, 14 and 21 days post infection. They were prepared for scanning electron microscopic observation and observed by ISI Korea DS-130C SEM at an accelerating voltage of 10 Kv. All worms were elongated and ventrally curved. Their ventral suckers were located in anterior 3/5∼1/3 level. The oral and ventral suckers had 10 and 6 type II sensory papillae respectively in a circular band on their lips. The ventro-anterior and ventro-middle surface of juvenile worms (2-day, 5-day and 7-day old) were regularly arranged with the spines of which tips diverged into 3 to 6 points, and their ventro-posterior surface were arranged with the peg-like single-tipped spines. The ventral surface of adult worms (2-week and 3-week old) was armed with many scale-like spines; 9∼11 pointed ones on anterior body, 7∼10 pointed on middle body and 6∼7 pointed on posterior body. The tegument spines on the dorsal surface were similar to those of ventral side in their shape and distribution. The tegument of juvenile worms was covered with cobblestone-like cytoplasmic processes, however they were changed into velvety texture in that of adults. The ciliated type I sensory papillae appeared biilaterally on the tegument of both side, and they were distributed on anterior tegument to ventral sucker level in group of 3∼8 ones. Destruction and shedding of tegument suggesing worm death and discharge were observed in 3-week old worms. From the above results, it is considered that the tegument of M. orientalis continued to differentiate until 2 weeks after infection, and it was shedded from the body of 3-week old worms.

An anthelmintic trial of albendazole was carried out an total of 186 inhabitants of Namhaegun, Kyongsangnam-do. For this purpose they were examined for their intestinal parasites, by cellophane thick smear and/or anal swab techniques before and 2 weeks after anthelmintic treatment. The examinations revealed A. lumbricoides 5.9%, T. trichiura 26.9%, E. vermicularis 52.4%, Echinostomia sp. 0.02% and Taenia sp. 0.01%. The infected cases were treated with 400㎎ single dose of albendazola. The egg negative conversion rate(NCR) and the egg reduction rate(ERR) were calculated based upon the results of pre and post-fecal examinations. For Ascaris, NCR was 87.5%, ERR 97.1%, and NCR 51.1% and ERR 78.6% for Trichuris. NCR was 100% for Enterobius. Albendazole(Alzental) is regarded as one of recommendable anthelmintics for the nationwide mass treatment programme of intestinal nematodes especially for ascariasis.

This paper presents a new vibration control device by which the mass and damping of a structure is increased equivalently. The vibration control system, named toggle-rotational inertia-viscous damper, can be utilized effectively in applications of small structural drift. Numerical analysis shows that because the relative drift of a structure can be effectively amplified by the toggle system, the device has a great performance in the vibration control without the increase of the damper capacity and size. It is also observed that vibration control effects is caused by the increase of equivalent mass and damping due to the rotational inertia and damping of the device.

The electrochemical reaction of cytochrome C varied with promotors and electrolytes. Among electron transfer carriers, 4-4' bipyridine(PyPy) showed good redox response using 20 mM phosphate solution as electrolyte and the case of Bis(4 pyridyl) bisulphide(PySSPy) as promotor showed same result using 0.2M Sodium cacodylate as electrolyte tested cyclic voltammetry method. Between electrodes, Au electrode is better behaviour than ITO electrode. 0.21M Tris, 0.24M Cacodylate acid showed the most effective electrochemical characteristics as electrolyte.

Juvenile polyp, also known as a retention polyp because they contain mucin cysts, is a relatively common hamartomatous lesion in chlidhood. It occurs in 1-2% of children and young adults; however it is uncommon in adulthood. Juvenile polyp is rare in the first year of life and is thus presumed to be acquired and not congenital. It is pedunculated, 2-3 cm in size, red-tan in colour, smooth and always shows fluid filled cystic spaces on cut surface. Histologically, Juvenile polyps are hamartomatous with distended, mucus-filled glands, often with cystic dilatation and edematous lamina propria containing abundant vasculature. The most common manifestation is rectal bleeding produced by auto-amputation of the polyp. Juvenile polyp has been considered not to be at increased risk of developing carcinoma. However, atypical epithelium is observed in some lesions, especially in larger polyps, which may give rise to adenoma and subsequent malignant transformation. Therefore the diagnosis of solitary juvenile polyp should not be made only with colonoscopy and biopsy, but should be totally resected endoscopically for pathologic evaluation. About 90% of the lesions are solitary and localized within 20cm from anal verge. In Korea, there are some reports of juvenile polyps located in the rectosigmoid colon. We report one case of juvenile polyp in adolescent that presented as a hematochezia & abdominal pain, which is located at right colon.

Praziquantel(Cestocide^ⓡ), Korean product, was tested for its efficacy in the treatment of Taenia saginata and Diphylobothrium latum infection during the period from May 1983 to October 1985, A total of 30 patients were treated with 10~30㎎/㎏ single dose of praziquantel and purged with 20~30g of magnesium sulfate to recover the worms. The results were as follows: 1. The patients were 26 cases of T. saginata and 4 cases of D. latum and after the treatment all of them discharged tapeworm segments with or without their scolices. The scolex recovery rate was 43.3%(from 11 and 2 cases of T. saginata and D. Iatum respectively). 2. The follow[up examination for eggs and/or proglottides performed 2~3 months later or 11 out of 17 scolex-unidentified cases gave all negative results. From the results it is concluded that praziquantel(Cestocide^ⓡ) in 10㎎/㎏ single dose is highly effective in treatment of these tapeworm infections.

Modal mass is essential to analyze structural response under disturbance and to design the vibration control devices used to enhance the serviceability of structure. Modal mass differs from that of analytic mathematical model due to the error generated from analytical assumption and construction. Therefore, the objective of this study is to proposed to calculate the modal mass of structure based on the system identification. And the proposed method is applied to two examples, the single DOF system and the slab of apartment.
