The purpose of this study was to observe the reaction of human pulpal tissue and root surface after applicatiet; of an intrusive orthodontic force. The experimental material consisted of thirty-six intact teeth from aged 10 to 25 years: These teeth were intruded with forces ranging from 100 to 500 grams with fixed appliances under controlled conditions for 1 week to3 months Four of the controlateral teeth were extracted without treatment and served as controls. Immediately after extraction, apical 3rd of each roots used for the scanning electron microscopic findings and ano part of each roots used for thelight microscopic findings. Serial sections, 5 microns thick, through the pulp in an axiobuccolingual direction were prepared and stained with hematoxylin and eosin. Photomicrographs were made of a selected, representative area for comparison. The following results were obtained; 1. The main pulpal changes in the experimental materials included the degenerative changes, such as excessive vacuolization of the odontoblastic layer, congestion, hemorrhage and cytolysis of vascular endothelial cells. 2. The pulpal damages were more related to the magnitude of force employed than the duration. 3. The pulpal damages were repaired with time. 4. Teeth with completed apices exhibited more severe changes than teeth with open apices. 5. The root resorption was more related to the duration of force employed than the magnitude.

The effects of various nitrogen sources on ascus formation were investigated. 1) The addition of 1% peptone was the most effective on ascus formation amongthe media added (NH_4)_2SO_4, NaNO_3, and peptone to Koji extract, respectively. 2) DL-aspartic acid, L-cystine, L-glutamic acid, L-glycine, L-isoleucine, DL-serine, DL-tryptophan, and L-tyrosine stimulated the ascus formation, and α-alanine, L-arginine, DL-phenylalanine, and L-asparagine stimulated the growth in media in which amino acid is the sole source of nitrogen. 3) The effects of addition of amino acid to Koji extract medium on ascus formation are similar as the results in media in which amino acid is the sole source of nitrogen. 4) The mixture of effective amino acids on ascus formation stimulated the formation remarkably, but the stimulatory effects of amino acids were abolished by addition of α-alanine and L-arginine. These results indicate that-α-alanine and L-arginine inhibit the ascus formation.

This study was designed to investigate the change of chemical composition of the serum and urine in humans after the MSG administration. Healthy Korean adult men were used for experimental objects. The experimental groups were divided into three groups receiving, one, three and five gram dosages, respectively. These groups were investigated as to the change of chemical composition in the serum and urine 2 and 24 hours after the administration. These findings were compared with the pre-administration condition. The results obtained are summarized as follows: 1) Among all experimental groups, the pH value, the non-protein nitrogen and the protein nitrogen content in the serum showed no marked changes after the administration, as compared to before the administration. 2) Among all experimental groups, the ammonia-nitrogen content in the serum, as compared to before the administration, decreased 2 hours after the administration but the urea-nitrogen content increased. 3) among all experimental groups, the blood sugar content in the serum increased slightly 2 hours after the administration, but the cotnent returned to the same level as before the administration. 4) Among all experimental groups, the albumin, α_1-, α_2- and γ-globulin content in the serum protein after the administration, as compared to before the administration, showed no market changes each time but the β-globulin content increased slightly after the administration. 5) Among all experimental groups, the urea-nitrogen and ammonia-nitrogen content in the urine after the administration, as compared to before the administration, increased slightly but the creatine and creatinine content showed no marked changes each time.

酵母의 胞子形成에 미치는 Vitamine의 影響

河德模 東國大學校 1968 論文集 Vol.5 No.-

The effects of Vitamines on the sporulation of Schizosaccharomyces octosporus on the medium containing one of amino acids or casamino acid as the sole source of nitrogen was investigated. The results are as follows: The percentage of cells producing spores is appreciably increased on the medium containing inositol and Ca-pantothenate. Whereas, when nocotinic acid and biotin are present, the percentage is decreased. No such effects are observed when thiamine riboflavin, pridoxine, nicotinic acid, biotin, folic acid, and p-aminobenzoic acid are added. The yeast required inesitol, Ca-pantothenate, nocotinic acid, and biotin for growth. These results indicate that inositol and Ca-pantothenate are effective on both of sporulation and growth, nicotinic and biotin inhibit sporulation and stimulate only growth.

Pseudomonas acidovorans, Pseudomonas testosteroni 및 comamonas terrigena의 균체효소의 전기영동 pattern에 의한 분류학적 비교

하덕모 東國大學校 1990 論文集 Vol.29 No.-

The relationship among thirty-one strains belonging to Pseudomonas acidovorans, Pseudomonas testosteroni, Comamonas terrigena, and pseudomonas aerugionsa were studied by comparing four enzymes (glutamate dehydrogenase, malate dehydrogenase, isocitrate dehydrogenase, fumarase) electrophoretically. The enzyme patterns of the strains whithin each species of Pseudomonas acidovorans, Pseudomonas testosteroni and Comamonas terrigena, were simliar, but distinguishable clearly from each other by their species. However, the strains within Pseudomonas testosteroni showed lower levels similarity than in the other two species, indication more genetic heterogeneity. Notably higher levels of the similarity within the three species were exhibited than whith Pseudomonas aeruginosa. It is suggested that the three species were closly related phylogenetically and Pseudomonas acidovorans and Pseudomonas testosteroni should be reclassified to the genus Comamonas.

간질성 신염은 신장의 간질을 선택적으로 침범하는 염증성 질환으로 여러가지 원인에 의해 유발되며, 이 중 약물에 의한 경우는 각종 항생제, 비스테로이드성 진통제, 항경련제, 이뇨제, 면역억제제등에 의한 증례들이 보고되고 있다. 현재 각종 질환-특히 만성질환-의 치료에서 한약이 차지하는 비중이 적지 않으나, 그 각각의 성분들이 유발할 수 있는 부작용들에 대한 연구는 거의 없는 실정이다. 저자들은 관절염 치료를 위해 중국산 한약을 복용한 후 복통, 피로감 및 육안적 혈뇨를 주소로 내원한 두 환자에서, 단백뇨와 신기능 장애를 보여 시행한 신조직 생검상 급성 간질성 신염에 합당한 병리학적 소견을 보이고, 한약 복용 중지 후 급속한 회복을 보여, 한약에 의해 유발된 것으로 사료되는 급성 간질성 신염 2예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Acute interstitial nephritis is a disease characterized by renal interstitial inflammatory cell infiltration and acute renal functional deterioration. This is caused mainly by antibiotics, NSAID and diuretics such as thiazide, but cases induced by herb medication are rare. We experienced two cases of acute interstitial nephritis after treatment with herb medication. One 71-year-old female patient and the other 60-year-old female were admitted to the hospital because of general weakness and gross hematuria. Microscopic hematuria, pyuria, and proteinuria were presented. After definitive diagnosis with a renal biopsy, we noted rapid recovery of renal function by drug withdrawal and steroid therapy. We report these cases with a review of the referenced literatures. Key Words : Herb medication, Acute Interstitial nephritis.

본 연구는 소총사수 P의 집중력 훈련에 관한 것이다. P 선수는 만 21세의 남자선수로서 운동경력은 8년이며, 10M 공기소총이 주종목이다. 집중력훈련은 단일사례실험 중 가장 단순한 시계열 설계인 AB 설계를 적용하였다. A단계에서 집중력, 주의력 질문지가 1-2주 간격으로 4회 반복측정 되었으며, B단계는 7월-10월까지 집중력 훈련이 진행되는 기간으로 개별면담과 질문지 측정, 수행평가를 위한 시합기록이 수집되었다. 집중력 질문지는 1개월에 1회 측정되었고, 주의력 검사지는 집중훈련 전과 후에 각각 한차례 시행되었다. 집중 루틴은 선수의 개인적 습관과 장점을 최대한 존중하여 훈련과 최고시합 때 습관적으로 하는 행동과 생각을 포함시켜 상당한 시합 부담 상황에서도 최고시합때의 행동과 생각의 흐름을 유지할 수 있도록 강력한 의미를 가진 행위와 키워드로 구성하였다. 완성된 루틴 프로그램은 4개월 훈련 후 집중력과 주의력, 수행평가를 실시하였다. 훈련결과 루틴 훈련은 집중조절 능력을 향상시켰으며, 주의유형은 긍정적인 형태는 증가하고 부정적 형태는 감소하였다. 수행 기록은 루틴 훈련 과정에서 출전한 5회 시합에서 모두 결선에 진출하므로서 수행향상에도 기여한 것으로 밝혀졌다. This study is about a concentration training of a rifle Marksman, P, The male Marksman P is 21 years old, and has played a rifle for eight years. His major is 10M air rifle. We apply AB design which is the simplest time-series design among single case experiments. In A step, we have applied the questionnaire for examining the ability of concentration and attentiveness for four times at an interval of 1 or 2 weeks. In B step, we developed a programme for improving the concentration training and applied it to the player. During the training in B step, which had continued from July to October, we have collected individual interviews, survey, records of games in order to evaluate achievement. The questionnaire for concentration has been served once a month, and the TAIS has been operated once each time before and after the concentration training. The concentration routine is directed to the way of considering the athlete's personal habit and merit most. Therefore, the concentration routine includes the essential matters of habitual acting and thought in ordinary training and in the final match. The concentration routine is consist of powerful meaningful movement and keyword in order to maintain the stream of movement and thought at the final match even though the Marksman is under the heavy pressure of the game. The practice evaluation has been done by a completed routine programme after the four-month-training. After examining the result of the evaluation, the concentration training improves the ability of controlling concentration. The positive type of TAIS is increased and the negative type is decreased. About the record of achievement, the player had advanced to the final once before the training, on the other hand, advanced to all the five final matches after the training. Consequently, it is discovered that the concentration training contributes to the achievement.

The College of Engineering was specialized to have a sole function for supplying technical high school teachers in 1977 and referred to as the College of Industrial Education according to the Government's policy. The economic impact mainly due to the oil-crises caused a severe problem to this college, namely discrepancy of supply to demand scale. Accordingly the number of student enrollment was to be fluctuated from 479 in 1979 through 800 in 1979 and 900 in 1980 to 430 in 1981. And the engineering departments have been attached to this Engineering Education College since 1981. These circumstanses met singnificant inefficiency in facility operation. This program aims at providing an overall relocation of the college facilities and preparing the practical system to make the joint-operation possible taking into account circulation, academic stream, budget, maintenance, etc. However this study could not get optimal spacing but some trade-off, considering the current situation.

The purpose of the present study was first, to evaluate the relationship between composite surface conversion and surface discoloration, second. to know if there was difference in surface discoloration between celluloid-strip-finished composite surface and polished surface. In addition, the discoloration of composite surface was also evaluated with visual inspection or digital camera with high resolution monitor. Z-100 Tetric Ceram. Spectrum. and Aelitiril were used. The composite surfaces were celluloid-strip finished (group1) , polished (group 2) . celluloid- strip finished under nitrogen gas purging (group 3) or only light cured without finishing or polishing under nitrogen gas purging (group 4) . The microhardness of each samples were also measured in each group, The samples of each group were also divided into 4 subgroup whether they were immediately placed in disclosing solution (0.2% Erythrosin, pH 7.0) (subgroup1 ) . l day after light curing(subgroup 2 ) .3day after light rulings (subgroup3) or 7 day after light curing(subgroup4). The computer controlled spectrophotometer was used to determine CIELAB coordinates (L*, a * , b*) The amounts of color difference were compared. The results were as follows: 1.There was no difference in discoloration between celluloid strip finished composite surface and polished surface 2.The samples discolored more when they were placed in disclosing solution immediately after polymerization than other groups. 3.When the samples were light cured under nitrogen gas purging and without polishing process. they discolored more than other groups even through they showed higher microhardness. 4.With visual inspection or digital camera. only a limited information was available in detecting composite surface discolation
