吳德鐵,李賢順 제주대학교 1983 논문집 Vol.16 No.-

1. 光合成細菌 R. rubrum을 Ortho P, Pyro P가 各各 包含된 培地로 明ㆍ暗狀態로 培養하여 收率, pH變化, Polyphosphate含量등을 조사하였다. 2. pH는 Ortho P배지보다 Pyro P배지에서 더 높았다. 3. 收率은 明培養때는 Ortho P배지에서가 낮고 暗培養인때는 反對였다. 4. Poly P함량은 明ㆍ暗區別 없이 Pyro P배지에서 월등히 높았다. 5. 암배양의 경우 Ortho P배지에서 배양할 때 상당량의 Pyro P가 生合成되는 것으로 보인다. 6. Pyro P는 어떤 經路이건 직접 long chain Poly P合成에 관여되는 것으로 보인다. 1. Photosynthetic Bacterium R. rubrum was cultured in Orthophosphate or Pyrophosphate-containing medium under light or dark condition. Cell Yeild, pH Change, Polyphosphate content were investigated. 2. pH of Orthophosphate medium was low than Pyrophosphate medium. 3. Cell Yield was low with Orthophosphate medium under light, but was low with Pyrophosphate medium in case of dark culture. 4. Polyphosphate content was always very high with Pyrophosphate medium. 5. It looks likely that under dark culture with Orthophosphate medium R. rubrum synthesize Pyrophosphate with substantial amounts. 6. It seems that Pyrophosphate concern directly in biosynthesis of long chain Polyphosphate.

Distribution of total coliform bacteria (T.C), fecal coliform bacteria (F C) and general bacteria (G.B)together with pH, water temperature and air temperature were surveyed periodically from December 1979 to 1980 at sic sites in Jeju Harbor. The sampling was done from both surface and bottom level for each sites. The average water temperature throughout the period of investigation was 15˚~16.75℃. It was indicated that at the estuary where a large amount of inland water is flowing in, the temperature of surface water showed lower than bottom layer. The lowest and the highest pH showed at site 4 and site I whose value were 7.83 and 8.33 respectively. Overall pH value throughout the investigation period was between 7.7 and 8.6. The highest viable counts of TC, FC and GB were observed on site 4 with 86,166/100ml, 9,208/100ml and 52,496/ml respectively, while the lowest counts were on site 1 with 245/100ml, 81/100ml and 425/ml respectively. Differences in counts between surface and bottom were not much agreeable throughout the tested sites, but surface levels were remarkably higher than bottom for every sites. The ratio of Fecal coliform to Total coliform(Fc : Tc) were ranged from 4.46 % to 37.9 % Reviewing the data obtained in this investigation, it is obvious that a large amount of fecal bacteria are flowing into Jeju harbor through untreated city sewage. Therefore, it is desirable to set up sewage disposal facilities in order to prevent serious pollution problems with pathogenic bacteria such as Salmonella ,Vibrio etc.

오덕철,이현순 제주대학교 1984 논문집 Vol.17 No.-

1. Korean strain of wild type of Rhodospirillum rubrum excretes water-soluble pigments into the medium when grown anaerobically under light. 2. The absorption spectrum of the supernatant medium shows peaks at 392.5 (main peak), 500,535 mp together with shoulders at 370, 555 mp. 3. Water-soluble pigments show pinkish-orange fluorescence under short-wave ultraviolet light. 4. The optical density of the supernatant medium increases markedly with time when aerated under dark, room temperature. 5. The culture of R. rubrum shows no distinct differences in the excretion of water-soluble pigments when cultured in orthophosphate or pyrophosphate medium as inorganic phosphate source. 6. It is postulated that the water-soluble pigments excreted by the wild type of R rubrum are mixture of a few kinds of porphyrins.

This study attempted to examine the differences of self - esteem, hopes, concerns and total stress scores of 110 kidney recipients in before(N=32) and fellowing kidney transplantation [1 to 6 months(N=29), 6 to 12 months(N=23), 12 to 36 months(N=26)] and utilizing severity rating scale of 44 potential stressors on a 5-point scale of 110 kidney recipients in before(N=32) and following kidney transplantation operation [1 to 6 months(N=29), 6 to 12 months(N=23), 12 to 24 months(N=15) and 24 to 36 months(N=11)]. On scores of hopes and total stress, pretransplant group exhibited significantly higher scores than three posttransplant recipient groups. But, it was found that there was no significant differences among four transplant kidney recipient groups on the scores of self - esteem and concerns. In the pretransplant group, craving for foods was identified as the most stressful event, on the contrary, changes in friends was identified as the lowest stressful events. In the 1 to 6 months posttransplant group, side effect of medications was identified as the most stressful event, however, loss of contact with dialysis patients was identified as the lowest stressful event. In the 6 to 12 months posttransplant group, cost of medication, changes in body appearance were identified as the most stressful event, on the other hand, managing of medications at home was identified as the lowest stressful event. In the 12 to 24 months posttransplant group, cost of medication and insurance coverage were identified as the most stressful event, but possibility of dying and competence of nursing staff were identified as the lowest stressful event. In the 24 to 36 months posttransplant group, changes of body appearance was identified as the most stressful event, on the contrary, possibility of infection was identified as the lowest stressful event. Insurance coverage was a continuing concern throughout posttransplant period.
