The inverted papilloma and squamous cell carcinoma are common neoplasia in the sinonasal cavity and nasopharynx, but the incidence of these tumors are very low and the study on the oncogenesis or biological activity of the tumor cells are not well known. This study was designed to evaluate the oncogenic roles of the p53 gene and the proliferative activity of the tumor cells in the inflammatory polyp, inverted papilloma and squamous cell carcinoma. The experiment was carried by the immunohistochemical stains about the p53 protein, PCNA and Ki-67, histochemical stain about the AgNORs. and flow cytometric analysis about the DNA ploidy using the formalin fixed paraffin embedded tissues. The frequency of the expression of p53 protein was 0%(0/16 cases) in the inflammatory polyps, 18.8% (3/16 cases) in the inverted papillomas, and 87.5%(14/16 cases) in the squamous cell carcinomas. The labelling index(%) of the PCNA and Ki-67 was 5.3% and 3.3% in the inflammatoy polyps, 29.6% and 25.2% in the inverted papillomas, and 51.9% and 36.8% in the squamous cell carcinoma. The expression of the PCNA and Ki-67 was distributed in the periphery of the tumor islands of the inverted papilloma and was distributed in the both of center and periphery of the tumor islands of the squamous cell carcinoma. The number of nuclear AgNORs was increased in the order of inflammatory polyps (0.96), inverted papillomas(1.34) and squamous cell carcinoma(2.09). The frequency of the DNA aneuploidy was 0%(0/16 cases) in the inflammatory polyps, 18.8%(3/16 cases) in the inverted papillomas. and 12.5%(2/16 cases) in the squamous cell carcinomas. Above results indicates that the changes of the p53 gene and proliferative activity of the tumor cells are involved on the oncogenesis and the biological activity of the inverted papilloma or squamous cell carcinoma in the nasopharynx and sinonasa cavity.

A Study of Bendrix's View of Divinity in The End of the Affair

文基周 건국대학교 1976 論文集 Vol.3 No.1

The works of Graham Greene, a famous modern British writer, are largely coloured by Catholicism. In the light of this point, the thesis was selected upon The End of the Affaw among his works, and it has been studied as to the view of Divinity which was deemed to be possessed by Bendrix who was a main character of the luork. The analysis of Bendrix's view of divinity done in this thesis is not a theological one in the doctrine of Christianity but a psychological descriptien of his mental attitude toward God seen in the love affair. In other words, it is not easily undrrstood that he should hate and resent God in spite of his stand upon the divinity. Since he is to be called a man of atheism. This logical contradict, on the part of Bendrix it seems as such, no one will understand unless the motive of his view of divinity is depicted out. Simply speaking, the motive is that Bendrix made a frantic love to Sarah tvho was Henry's wife, and he wanted to be loved by lier in the same intensity. But how could he believe her love to be real while she had her own husband! Then he begins to doubt Sarah and, in turn, he feels jealousy and hatred to both Henry and Sarah. Bendrix's essential humanity as such is magnified so far as to revolt God, and at this very point his view of divinity derives itself. As to Bendrix, he sufffred from so much mental agonies because of Sarah. But at last he found real love of Sarah and he become satisfied. If the story had ended about here, how wondeful and how happy Bendrix would have been! But, alas, Sarah died a few days after he found her real love, and so Bendrix realized that what had happened so far was of an irresistible force surpassing human capability. He, hereby, blamecd God for the failure of things. Thus, all of the human pains Bendrix had undergone finally turned into an intense hatred and resentnlent against God. Such human agonies are not only the Bendrix's own problem but all of the people who suffer from frustrations. Graham Greene, a prominent modern novelist, has clearly showed us such important human. problem through the Bendrix's view of divinity· in The End of the Affair, one of his noted works. Whereas it is one of the biggest pending questions for the whole modern people to settle down, the author's suggestion on the matter through his work is to be highly appreciated

肝내 알데히드 탈수소효소 활성의 변동

문전옥,김태완,백기주,김기헌 부산대학교 신약개발연구소 1994 藥學硏究誌 Vol.28 No.1

It was reported that hepatic aldehyde dehydrogenase(ALDH) activity was depressed in alcoholic liver diseases, however there was few report that explain the reason of depressed ALDH activity. We have attempted to correlate the decrease of hepatic ALDH activity with the active oxygen species which generated at elevated rates in the proliferated microsomes by chronic ethanol feeding. The susceptibilities of the hepatic ALDH activity to active oxygen generated by xanthine-xanthine oxidase system and FeSO₄-H₂O₂ system were studied. Incubation of ALDH with 2×10³ xanthine oxidase for 30 min at 25℃ resulted in the decrease of enzyme activity to 60%, and 55% of ALDH activity was retained after exposure to FeSO₄4-H₂O₂ system for 20 min. Alteration in the ALDH activity after administration of ethanol in rat liver was investigated. Whereas the mitochodrial ALDH activity was increased, the microsomal activity was depressed in ethanol-treated rat. Induced microsomal ALDH activity was observed by treatment of phenobarbital or 3-methylcholanthrene in the liver of rats chronically fed alcohol. Since the ALDH catalyses the oxidation of a wide variety of aliphatic and aromatic aldehydes, it is suggested that the alteration in the ALDH activity by various factors including the active oxygen affects the physiological states of liver administrated ethanol chronically, which may in turn to lead to liver disease.

The authors investigated HBeAg and anti-HBe in 1,000 cases(male 941, female 59) of HBsAg positive among the 225,512 blood donors in Seoul Nambu Blood Center in 1994. HBeAg and anti-HBe was detected by the method Enzyme Immunoassy. The results obtained were as follows ; 1. HBeAg and anti-HBe positive rates were detected 498 cases(49.8%) and 445 cases(44.5%) respectively among 1,000 cases HBsAg positive blood donors. 2. In HBsAg positive carriers, HBeAg positive rates were not significantly different between anti-HBe positive rates, but in sex were significantly different between HBeAg positive rates and anti-HBe positive rates. 3. HBeAg positive 498 cases were analyzed with age and it was found percentages of positive rates were 63.6% in 1st decade, 53.7% in 2nd decade, 20.6% in 3rd decade, 19.6% in 4th decade and 8.3% in over 5th decade, but anti-HBe positive 447 cases were 32.4% in 1st decade, 40.5% in 2nd decade, 69.2% in 3rd decade, 78.3% in 4th decade and 91. 7% in above 5th decade. 4. HBeAg positive rate decreased stepwise with age, while anti-HBe positive rate increased stepwise with age. 5. ALT abnormal cases in the HBeAg positive donors were higher than normal cases, but ALT normal cases in the anit-HBe positive donors were higher than abnormal cases.

凍結明太肉의 貯藏中에 일어나는 理化學的變化(第1報) : 明太肉에 對한 아미노酸, 有機酸 및 糖類의 貯藏效果 Preservative Effects of Some Amino Acid, Organic Acid and Sugars on Alaska-Pollack Fillet

韓南珠,金文基,權泰鳳,吳成基 慶熙大學校 1980 論文集 Vol.10 No.-

The effects of sugar (D-sorbitol, D-xylose), organic acid (Na-citrate) and amino acid (monosodium glutamate) on the physicochemical properties of frozen "Alaska-pollack" fillet containing 500mg% of sucrose at 15℃ were studied by the quantitative measurements of myofibrillar Mg^2+ -ATPase activity, trimethylamine-N, total protein, pH and textural variations with the lapse of time. The results were compared with each other at different concentration levels (125-500mg%). 1. The more higher the concentration of additives, were observed the more higher myofibrillar Mg^2+ - ATPase activity and pH value. In contrast, however, trimethylamine-N content was decreased with the concentration increase. 2. All the "Kamaboko" groups containing additives at different concentration levels maintained almost similar elasticity. On the other hand, they were not only easily crumbled but also markedly decreased hardness, cohesiveness and gumminess with the lapse of time. 3. The D-sorbitol showed inferior textural characteristics to other additives, and D-xylose gave heavy color during the "Kamaboko" processing. 4. D-sorbitol groups increased cohesiveness and gumminess, respectively, with the concentration Increase. On the other hand, hardness was decreased in the sodium citrate groups.

본 연구는 원예치료와 미술치료가 학교부적응 청소년의 자아개념, 내적 통제력, 불안감소에 미치는 영향을 조사하고자 실시되었으며, 그 결과는 각 치료의 효과성이 비교·분석되었다. 인천 남구에 위치한 W공업고등학교에서 대조군 15명, 원예치료군 15명, 미술치료군 15명을 주 2회씩 2001년 9월 27일부터 12월 13일까지 원예치료군에는 원예치료 프로그램을 미술치료군에는 미술치료프로그램을 실시하였다. 원예치료 및 미술치료는 각각 전문 치료사에 의해서 행해졌다. 원예치료 및 미술치료 프로그램의 효과를 알아보고자 자아개념(Self-Concept Scale), 내적 통제력 척도(Inner-Control Scale), 특성불안 척도(Trait-Anxiety Scale)을 각 프로그램의 실시전과 실시후로 조사하여 비교하였다. 원예치료군에 있어서는 자아개념척도 중 자아수용, 성격적 자아, 총 자아 긍정 항목에서 통계적으로 유의한 향상을 보였고, 특성불안척도에서는 우울 및 불안 항목에서 매우 유의한 감소를 나타내었다. 한편, 미술치료군에 있어서는 내적통제력과 특성불안척도중 자신감이 유의하게 향상된 것으로 나타났다. 이상의 결과를 종합하여 볼 때, 원예치료군은 프로그램 과정중 자기표현의 기회를 제공함으로써 자아개념이 향상되었으며, 또한, 공동작업을 하는 집단 프로그램을 통하여 내면의 불안과 갈등이 완화되었다고 판단된다. 반면, 미술치료군은 치료자와의 개인적인 상담과정을 통하여 내면의 불안과 갈등이 완화되었고, 지점토 및 칼라믹스 만들기 등 활동적인 프로그램을 통하여 내면의 감정을 통제하는 능력이 향상되었다고 판단된다. This study was conducted to evaluate the effect of HT (horticultural therapy) and AT (art therapy) on the changes of self-concept, inner control, trait anxiety of the school maladjusted adolescents. 45 school maladaptive of teenage students participated in therapy program at the W high school were randomly assigned to 3 groups: 15 for the horticultural therapy, 15 for art therapy, 15 for control group. The program were carried out from Sep. 27 to Dec. 13, 2001 as an activity group. Activity group attended twice a week for 1 hour. For evaluation of the effectiveness of each therapy, Self-Concept Scale, Inner-Control Scale, Trait-anxiety Scale were used 2 times, that is, before/after HT or AT program. According to the results, self satisfiction, personal self, and total positive self items among Self-Concept Scale were significantly improved, and tension and anxiety item among Trait anxiety Scale were significantly decreased in HT group. On the other hand, in AT group, both inner control and self confidence item in Trait-anxiety Scale were significantly improved. In conclusion, in HT group it was suggested that the improvement of self concept could be brought about by being provided the chance of self expression during program and the alleviation of inner anxiety and discord resulted from group therapy program in which joint work have been provided. In case of AT group, it was logically postulated that the alleviation of inner anxiety and discord resulted from personal counselling with AT therapist during program and the improvement of inner control was caused by active program such as painting paper clay, making color mix, and etc.

윤기은,문희주,박정오 서울保健大學 1996 論文集 Vol.16 No.1

The purpose of this study was to analyze the concentration of serum type w Ⅳcollagen in HBV-DNA positive patients. The results were as follows. 1. As HBV-DNA concentration of serum grew higher, that of serum type Ⅳcollagen became lower gradually. 2. Total LDH activity had a significant relationship with concentration of serum type Ⅳcollagen up to l,000ng/mL. As HBV-DNA concentration of serum grew higher, total LDH activity became lower gradually. 3. Correlation serum type N collagen with AST(GOT) and ALT(GPT) appeared to have little relation compared to LDH. But each generally had the same change in direction. As HBV-DNA concentration of serum grew higher, those of AST and ALT were decreased drastically. These were no differences between the test group and a normal group.

정기영,김지훈,성열문,곽동주,추영배 경성대학교 공학기술연구소 2010 공학기술연구지 Vol.16 No.-

In order to investigate the possible application of ZnO films as a transparent conducting oxide (TCO) electrode for film-typed dye sensitized solar cell(F-DSC), ZnO:Al films were prepared by RF magnetron sputtering method. The effects of gas pressure on the structural and electrical properties of ZnO films were mainly studied experimentally. F-DSC using either a ZnO:Al or indium tin oxide (ITO) electrode were also fabricated separately under the same manufacturing conditions. The electro-optical conversion efficiency and fill factor of the F-DSCs using both ZnO:Al and ITO transparent conducting electrodes were measured and compared with each other. ZnO:Al films showed the minimum resistivity of 2.6 x10^(-3)Ω-cm and a transmittance of 91.7% under the experimental conditions of doping concentration of 2 wt% of Al₂0₃ and gas pressure of 5mTorr. ITO films fabricated at 5mTorr of gas pressure also showed the minimum resistivity of 1.5x10^(-3)Ω-cm and transmittance of 92.1%. Although the electrical resistivity of ZnO:Al is higher than that of ITO, the conversion efficiency of F-DSC using ZnO:Al was comparable with that of F-DSC using ITO. The conversion efficiency of F-DSCs using ZnO:Al and ITO electrodes are about 2.8% and 2.9%, respectively.
