The antibacterial efficacy of a mouthrinse(Denta Gargle) containing CPC(cetylpyridinium chloride), NaF and UDCA(ursodeoxycholic acid), on major periodontopathogens, was in vitro examined and compared with that of Listerine by a broth dilution method. The bacteria tested were Actinobacillus actinomycetemcomitans, Bacteroides forsythus, Fusobacterium nucleatum subsp. vincentii, Prevotella intermedia, Porphyromonas gingivalis and Treponema denticola. The growth of all the bacteria were completely inhibited by a 1-min exposure to the both mouthrinses. When diluted at 1:5 or more, all bacteria analyzed but P. intermedia were not inhibited by Listerine. In contrast, Denta Gargle showed highly increased maximum inhibitory dilutions(MID) against all periodontopathogens included in this study, with MIDs ranging from 5-fold(F. nucleatum) to 160-fold dilutions(P. intermedia). The MIDs against A. actinomycetemcomitans, B. forsythus, P. gingivalis and T. denticola. were 1:40, 1:80, 1:80 and 1:80, respectively.

빅데이터 분석에 있어 감성사전은 감성분석의 정확도를 제고하는 데 매우 중요한 요소이다. 그러나 감성사전을 구축할 때 긍, 부정 판단에는 주관적인 측면이 들어갈 수밖에 없다. 그럼에도 그동안 감성사전은 일반인의 판단에 근거한 경우가 많아. 한국어 전문가의 판단이 필요했다. 이에 빅데이터 분석 영역 전문가와 한국어 분야 전문가의 체계적 판정을 통해서 비교적 객관적인 긍정 부정값을 도출해 내야 한다. 더욱이 기존에는 실질형태소에 치중되어 있어, 분석의 정확도에 한계가 있었다. 이에 본 연구의 목적은 실질형태소뿐 아니라, 형식형태소와 정도부사까지 망라한 최대의 한국어 감성사전을 경영 및 한국어 전문가 들에 의하여 구축한 방법을 제안하고 그 성과를 제시하는 것이다.

N/A Objectives: Renal transplantation has become the therapy of choice for patients suffering from end-stage renal disease. But because of progressive disparity between the number of patients in needs of a transplant and the number of ideal kidneys available for transplantation, increasing numbers of kidneys are recovered for transplantation from donors that are not considered ideal, especially from donors over the age of 55. In country such as Korea, the number of cadaveric transplants is limited due to cultural and religious prejudices of the population, poor legal definition and deficient organization of cadaveric donor work-up. Therefore the main source is living related donors(LRD), especially the parent. But in Korea, there is few reports about the influence of donor age on outcome in living related kidney transplantation. Thus we performed this study to estimate the influence of donor age in itself on the outcome of the one HLA-haplotype mismatched living related kidney transplantation. Methods: The effect of donor age on the outcome of One HLA-haplotype mismatched living related kidney transplantation was studied in 71 recipients who under- went kidney transplantation from January 1981 to March 1995. The outcomes of 25 recipients from the older age group(?55 years: Group A) and 46 recipients from the younger age group(<55 years: Group B) were retrospectively reviewed. Patient death with a functioning graft was considered graft loss. Results: Demographic characteristics between 2 groups were similar, The 1-year and 3-year patient survival rates in recipients(group A and B) were similar regardless of donor age(96.0% and 90.8% vs.97.4% and 90.3%, respectively). The 1-year and 3-year graft survival rates in recipients(group A and B) were not significantly different (91.4% and 63.9% vs 92.7% and 79.3%, respectively). The mean levels of serum creatinine at discharge were significantly higher in group A. Short-term and intermediate-term renal function, as assessed by serum creatinine, was inferior in the group A throughout the follow-up periods of 3 years. The causes of graft loss in the first 3 years after transplantation were irreversible rejection(71%) and the patient death with functioning graft(29%) in group A, while the causes of graft loss in group B were irreversible rejection(50%), patient death with a functioning graft(40%) and technical reason(10%). Conclusion: These results of our analysis suggest that similar outcome can be achieved after living related renal transplantation from older donor. Therefore the kidneys may be used from donors over 55 years old on condition that the donors undergo complete and exhaustive work-up.
