朴孝英,李潤培 조선대학교 기초과학연구소 1992 自然科學硏究 Vol.15 No.1

Industrial robots generally have five or six degree of freedom. But, the simple robots being used in manufacturing plants are usually below four degree of freedom, and these are proceeded by the sequential action according to the instruction or indication. Therefore, the objective of this paper is to be simple articulated manipulator so as to improve flexibility, performance and processing speed of machine's arm, articulated manipulator, which is composed of two or more joints. To achive this objective, we will propose algorithm which makes parallel processing possible according to proper division of each joint-action of articulated manipulator. We will apply it to the articulated manipulator.

We investigated the degree of microbiological contamination about keyboard and mouse of computer, cellular phone, and surface of can of drinks clooected from vending machine. In this study, it showed that keyboard and mouse of computer in PC game room, cellular phone, and the surface of can of drinks from vending machine were contaminated by various microorganisms. In the case of keyboard and mouse of computer, various kinds of bacteria and fungi including Staphylococcus aureus, Staphyolcoccus epidermidis, Streptococcus mitis, streptococcus salivarius, Escherichia coli, Enterobacter sp., β- hemolytic Bacillus, Pseudomonas sp., salmonella sp., Candida sp. were isolated on solid selective media. keyboards and mouses of computers in PC game rooms located nearby hospitals showed higher contamination than those of PC game rooms located around colleges or apartments. In the case of cellular phone and phone in the office, the results were quite similar to the previous work. Cellular phone was more contaminated than phone in the office. Many bacteria and fungi were distributed on the surface of can of drinks collected from vending machine. Cans from vending machines located near hospitals were proven to be more contaminated. fungi were isolated predominantly. As the results, we confirmed that keyboard and mouse of computer, cellular phone, and the surface of can of drinks collected from vending machine were seriously contaminated by various microorganisms.

Tailored Collar의 芯地 縫合法과 形態安定性에 關한 硏究

黃孝榮 영남이공대학 1980 論文集 Vol.9 No.-

I have tried to find out the most desirable and effective method of keeping the shape stability of the tailored collar by different collar stitching ways. Comparing my own method with that of, Stuart and Baird. The results are as follows : 1. The shape stability of the tailrrnd collar is affected by the padding Cloths, the stitching method and the stitching angle. 2. The woolen padding cloth is more effective to keep the shape stability of the tailored collar then the cotton one. 3. The manual stitching method is more desirable to keep it (shape stability), than the machine triangular stitching method. 4. When the bias of the padding cloth for the collar is right, the most effective stitching angle to keep it is 90° to the left and 189° to the right from the center of the back collar. 5. The more stitching angle is sharper. the more the desirable effect to keep is obtained in the machine triangular stitching method. 6. The rate of shrinking shows some difference according to the padding cloth and the stitching method. The width and length of the collar shows little shrinking rate but the part of the collar stand is big one.

오양효,윤소겸,공은진,김민정,김영부,박영민 대한감염학회 1995 감염 Vol.27 No.5

목 적 : 이미 보고되어 있는 파아지들의 경우, 일반적인 형태, 숙주역과 몇 가지의 성질만 연구되어 있으므로 보다 상세한 특성에 대한 연구가 필요한 상태이다. 본 연구에서는 해양으로부터 분리한 V. vulnificus를 숙주균으로 하여 투명한 용균반을 형성하는 파아지를 분리해 낸 다음, 분리된 V. vulnificus 파아지의 특징을 연구하고자하였다. 방 법 : V. vulnificus 를 숙주균으로 하여 해산물로부터, 숙주균에 특이적인 파아지를 분리하고, 농축 정제과정을 거쳐 파이지입자를 순수분리하였다. 파아지의 형태를 전자현미경으로 관찰하였으며, 분리된 파아지의 숙주특이성을 조사하고, 파아지 입자의 물리적 특성을 검토하기 위해, 온도 안정성시험, pH 안정성 시험을 실시하였다. 파아지의 흡착율, 파아지의 흡착율에 미치는 무기염 이온의 영향, 온도의 영향과 pH의 영향을 관찰하였다. 파이지의 일단증식곡선을 구하였으며 토끼 면역과 교차 중화 시험, 파아지 핵산의 특성, 구조단백질의 특성을 조사하였다. 결 과 : 전자현미경관찰결과 본 연구에서 분리한 파아지는 두부와 미부를 가지는 형태로 미부에 꼬리판과 꼬리섬유를 가지고 있었다. 파아지의 물리적성질시험 결과 파아지는 50℃이하의 온도에서 안정하였으며 중성pH영역에서 안정하고 산성과 알칼리 영역에서는 활성을 잃었으며 자외선에는 35초 조사에 50% 정도 불활성화 되었다. 파아지는 약 65%의 흡착율을 나타내었으며 흡착에 ??, ??을 요구하였다. 파아지입자가 안정한 온도와 pH영역에서는 흡착에 영향을 받지 않았으며 일단증식시험 결과 108 PHU/ml의 파아지 입자를 생산하였다. 정제한 파아지를 항원으로 하여 토끼에 면역한 항혈청에 파아지가 중화되었으며 파아지 핵산은 이중나선 DNA였다. 파아지의 구조단백질은 SDS-PAGE polyacrylamide gel 전기영동 결과 2개의 밴드를 나타내었다. 그리고 Western blotting 결과 파아지의 전기영동 결과와 동일한 위치의 밴드에서 항원성을 나타내었다. 결 론 : 인체병원균으로 중요성이 인식되고 있는 V. vulnificus는 해산물의 위생과 국민건강에 직접적인 영향을 미칠 수 있는 세균으로 이에 대한 활발한 연구가 요구되는 실정이다. 파아지의 분리율은 숙주균의 분리율에 의존하므로 숙주균의 해수내 분포에 영향을 미친다고 추측되며, 파아지는 숙주균에 감염되어 숙주균을 용균시키므로 숙주균의 개체수를 조절하여 생태학적 측면에서 중요한 기능을 담당하는 것으로 여겨진다. Background : Vibrio vulnificus causes severe wound infection and life-threatening septicemia. In this study we present the characteristics of V. vulnificus bacteriophage and the basis of pathogenicity study of V. vulnificus related on bacteriophage. Methods : We isolated bacteriophage for V.vulnificus from marine products and examined its physiological and biochemical characteristics, and the ultrastructure by electron microscopy (TEM,SEM). And also, we investigated host ranges, temperature stability, pH stability, inactivation by UV irradiation, DNA isolation and analysis and structural protein analysis of the bacteriophage. Results : The adsorption rate of bacteriophage was above 80% and had a little influence at 10-45℃ and pH5-10. Isolated bacteriophage was used to produce antiserum against rabbits and its antigenicity was investigated by cross-neutralization. Western blot analysis showed the capsid protein of bacteriophage had antigenicity. The bacteriophage had double-strand DNA. In restriction analysis, the phage DNA was digested HinfI. The structural protein of phage showed two bands of 34.7kDa and 18.4kDa on SDS-PAGE. Conclusion : The specificity of bacteriophage may be due to the specific binding site that be possessed by host strain surface. Therefore, it seems that virulent bacteriophage controls the number of host strain and then takes a role on natural marine environment.

윤효영,류동희,송영진 충북대학교 의과대학 충북대학교 의학연구소 2005 忠北醫大學術誌 Vol.15 No.2

위궤양에 의한 담관-위 누공은 매우 드문 질환이며 소화성 궤양에 의한 담관 누공의 경우 대부분 내과적 치료가 우선적으로 시행된다. 저자들은 내과적 치료에 호전되지 않는 궤양성 담관-위 누공을 외과적 절제술을 시행하여 완치하였기에 문헌고찰과 함께 보고하는 바이다. 64세 남자 환자가 15년 동안 지속된 식사 후 복통과 우상복부 동통을 주소로 내원하였다. 위 내시경 소견상 위전정부, 소만곡 후벽에 담즙이 역류하는 궤양저가 관찰되었으며 상복부위장관 촬영상 위전정부와 총수담관이 교통하는 소견이 있었으나 전산화복부단층 소견상 담석의 증거는 없었다. 담관-위누공 의심하에 체간미주신경절단술, 유문절제술, 담낭절제술, 총수담관절제술 후 환자는 퇴원하였다. Choledochogastric fistula complicated from gastric ulcer is very rare. Most of the internal biliary fistula by peptic ulcer were successfully managed with conservative treatment. Authors reported successful surgical resection of choledochogastric fistula caused by gastric ulcer. A (54-year old man visited our hospital complaining of postprandial abdominal pain and right upper quadrant pain for 15 years. He has a history of peptic ulcer medication for four years, recently. A gastrofiberscopy revealed ulceration on the posterior wall along the lesser curvature, gastric antrum with bile reflux from ulcer base, and histopathology of the biopsy specimen revealed an ulcer without evidence of malignancy. Barium upper gastrointestinal study showed fistula between stomach and common bile duct. In abdominal CT, there was a pneumobilia with dilated intrahepatic duct without common bile duct dilatation. After the diagnosis of choledochogastric fistula, we performed truncal vagotomy with antrectomy and cholecystectomy with resection of extrahepatic bile duct. The patient has remained well since his discharge from hospital.

The purpose of this work was to investigate the microbiological distribution and contamination from korean currency that is circulated generally among various kinds of people. Fifty 1,000-won bills were collected by seasons and regions for 18 months. supernatants derived from bills treated by ultrasonicator with .0.8% saline were inoculated and incubated on various selective media such as mannitol salt agar, potato dextrose agar, plate count agar, bismuth sulfite glucose glycine yeast extract agar, luria-Bertani agar. As the results, various kinds of bacteria and fungi including Staphylococcus aureus, Staphyolcoccus epidermidis, Streptococcus mitis, Streptococcus salivarius, Escherichia coli, Enterobacter sp., Salmonella sp., Pseudomonas sp., Candidasp. from 1,000-won bills grew on the solid media. Bacterial contamination was higher in spring and summer compared to winter, whereas fungal contaminatioj was predominated in winter. Especially, 1,000-won bills collected in fish markets and korean traditional markets were heavily contaminated by E. coli, staphylococcus aureus, Pseudomonas sp. Streptococcus sp.,Salmonella sp., and -hemolytic Bacillus. Similar results were obtained from 5,000-won bills and 10,000-won bills as well. In consequence, it was proven that korean currency of bank notes in current use was significantly contaminated by many pathogenic microorganisms.

女性 能力 開發을 위한 女性學課程 設置의 提案

玄永學,鄭世華,李男德,李效再 이화여자대학교 한국문화연구원 1976 韓國文化硏究院 論叢 Vol.28 No.-

For the past 20 years, there has been a substantial increase in the percentage of women going to colleges and universities in Korea: the statistics indicate that the male and female ratio changed from 87.3% to 12.2% in 1952 to 73.9% to 26.1% in 1974. Inspite of the increasing trend, some academic observers recently began to voice their opinions against higher education for women on the basis that Korean women, regardless of their education in an occupation or public life. The following trends partially support this opinion. First, the tendency of female students concentrating their major fields on a limited number of specializations, such as teachers' education, language, arts, nursing and medical technology, is a contrasting phenomenon with male students, who are more or less evenly distributed throughout all the areas of specialization as their major fields. Second, the remarkable increase in female labor participation for the past 10-15 years is largely contributed by women in the agricultural sector and manufacturing industries, as the percentage of women with higher education have shown not as much of an increase in the labor market as that of these with elementary level or less education. Furthermore, the percentage of women in professions and managerial occupations which would require college education for qualification toward has decreased from 2% in 1960 to 1.8% in 1970. Thirdly, a survey of Ewha graduates concerning their attitudes toward women's social role and college education presents revealing results of their conservatism and resignation sex equality and occupational roles. These findings certainly contradict the egalitarian principles of modern higher education and human potentials. However, there are now growing trends among female college students, with the awareness of changing sex roles, of taking seriously their future occupations and other social roles in addition to marriage. They are showing a greater concern for developing their potentials for professions and egalitarian roles for society, realizing the need for overcoming socio-cultural limitations as well as personal inertia. These are signs calling for new directions in women's education in Korea by introducing women studies programs which are designed to liberate women from the culturally conditioned state of self-awareness and the traditional status and role.

조기 위암의 림프절 전이 양상

윤효영 충북대학교 의과대학 충북대학교 의학연구소 1996 忠北醫大學術誌 Vol.6 No.2

진행성 위암에서 외과적 절제술중의 림프절 절제술에 대해서는 더 이상의 논란의 여지는 없으나 위절제술과 더불어 시행되는 광범위한 림프절 절제술은 수술후 자율 신경계의 손상, small capacity syndrome, dumping 증후군, 역류성 위염 등의 수술후 합병증 등이 문제가 되고 있어, 최근에는 조기 위암에서 축소 수술이 여러 병원에서 조심스럽게 논의되고 있다. (목적) 본 연구는 조기 위암에서 림프절 전이 양상을 규명하여 위축소 수술의 적응증을 알아보고자 하였다. (재료 및 방법) 1992년 9월부터 1995년 6월까지 충북대학교병원 외과에서 조기 위암으로 위아전 절제술 및 D2 이상의 림프절 곽청술을 시행한 49명의 환자를 대상으로 하여 병변의 위치, 심달도에 따른 림프절 전이 양상을 분석하였다. (결과) 총 49명 환자의 병변의 크기는 0.7-4.5cm까지 분포하였으며, 곽청된 림프절의 평균치는 29.9(범위 25-39)개였다. 심달도는 점막암이 20명, 점막하 암이 29명이었다. 점막암 환자중 병변의 위치에 상관없이 주변 림프절의 전이는 없었다. 점막하 암의 경우 병변이 위체부(n=10)에서 관찰될 때 10%(n=1)에서 림프절 전이가 발견되었으나 우위동맥을 포함한 위소만곡 주변의 림프절 전이는 관찰되지 않았다. 병변이 유문부에 위치하고 심달도가 점막하까지 침습한 경우에는 림프절 전이율은 21%(n=4)로 상대적으로 높은 전이율이 관찰되었다. (결론) 조기 위암이 웨체부에서 관찰되며 심달도가 점막에 국한된 경우에 소만곡부위 특히 우위동맥 주변의 림프절 전이는 드물 것으로 생각된다. 이 경우 주기적으로 추적 검사가 가능한 환자에서 내시경적 위절제술, 부분 위절제술 및 유문부 보존 위절제술 등의 축소 위절제술을 시도할 수 있겠다. Gastric surgeons routinely perform radical gastrectomy in patients with gastric cancer including more than D2 lymph node dissection. This approach is reasonable but it may increase morbidities such as ANS injury, small capacity syndrome, dumping syndrome and reflux gastritis. To diminish these operative morbidities and to secure a good quality of life after gastric operation, various methods of limited surgery for early gastric cancer(EGC) have evolved. To evaluate the pattern of lymph node metastasis according to depth of tumor invasion and location of tumor, we analysed 49 cases of EGC operated with more than D2 dissection from September 1992 to May 1995. Followings are our results. 1. Average number of lymph node dissection was 29.9(range 25-39). 2. There was no lymph node metastasis in mucosal cancers(n=20), 3. In submucosal cancers(n=29), the size, gross appearance and histologic classification of tumor were not predictive factors whether lymph node metastases take place or not 4. Tumors located in middle third of the stomach have less chance of lymph node metastasis than tumors located in antrum(10% vs 21%). 5. No metastasis was observed in either suprapyloric lymph node or the lesser curvature lymph node in EGC located in the middle third of the stomach.
