Background: Kidney injury molecule-1 (KIM-1) is known as a good ancillary marker of acute kidney injury (AKI) and its expression has also been observed in acute rejection and chronic graft dysfunction. We tested usefulness of KIM-1 as an indicator of acute and chronic renal graft injury by correlating KIM-1 expression with renal graft function and histology. Methods: A total of 133 zero-time biopsies and 42 follow-up biopsies obtained within 1 year posttransplantation were selected. Renal tubular KIM-1 staining was graded semiquantitatively from 0 to 3 and the extent of staining was expressed as the ratio of KIM-1 positive/CD10 positive proximal tubules using Image J program. Results: KIM-1 was positive in 39.8% of zero-time biopsies. KIM-1 positive cases were predominantly male and had received grafts from donors with older age, deceased donors, and poor renal function at the time of donation, compared with KIM-1 negative cases. KIM-1 expression showed correlation with delayed graft function and acute tubular necrosis. In comparison of KIM-1 expression between stable grafts (n=23) and grafts with dysfunction (n=19) at the time of repeated biopsy, the intensity/extent of KIM-1 staining and renal histology at zero-time did not differ significantly between the two groups. Histologically, KIM-1 expression was significantly increased with both acute and chronic changes of glomeruli, tubules and interstitium, peritubular capillaritis, and arteriolar hyalinosis. Conclusions: KIM-1 can be used as an ancillary marker of AKI and a nonspecific indicator of acute inflammation and tubulointerstitial fibrosis. However, KIM-1 expression at zero-time is not suitable for prediction of long-term graft dysfunction.
The purpose of this study is to investigate the effects of perception of success on mental power. The analysis was based on 218 Taekwon-do players divided into high performance: 62 players and average: 156 players. Perceptions of Success Questionnaire(POSQ) and Korean mental power questionnaire were mainly used in this study. Findings: Male players and high performance group, using MANOVA, show higher level of task goal orientation, specifically winning spirit, struggling efforts, endurance variables are higher on males and high performance players. According to regression analysis the mental power variables are strongly explaining the task goal orientation. Particularly, endurance, struggling efforts are mainly significant variables explaining 76% variation of task goal orientation. Competitive goal orientation, too, is strongly explained by mental power variables which explains 59% of total variance. This study is based on previous studies and theoretical background.
Immune hemolytic anemia(IHA) in patients after ABO-unmatched renal transplantation has been reported generally to be graft-cell-derived due to elaboration by the donor`s pas- senger B-lymphocytes of the antibodies directed against the recipients red cell antigens. The 58 cases of ABO-unmatched living donor renal transplants performed in Yonsei Medcial Center, from Jan. 1990 to Dec. 1991 were studied. The incidence of IHA was about 6%(4 among 58) and occurred only in group A recipients. All patients had IgG on their red blood cells and anti-A or anti-A,B antibodies. In renal transplant recipients with ABO-un- matched kidneys, autoantibody formation and hemolysis was a potential risk.
법질서 확립은 선진사회를 지향하는 우리나라에 있어 거부할 수 없는 방향이다. 그러나 사회적 갈등의 최종 종착점에 해당하는 집회시위에 대한 대처에 있어서 법질서확립이라는 방향은 사회적 갈등관리라고 하는 보다 큰 범주 안에서 이해되어야 할 것이다. 이러한 사회적 갈등관리의 성공적 수행은 집회시위 문화의 변화를 가져올 것이고 집회시위를 관리하는 경찰의 법집행에 대한 국민의 수용도를 높여줄 것이기 때문이다. 따라서 이 연구에서는 각국의 집회시위 대응 현황을 통하여 집회시위 대응 방식의 나아갈 바를 살펴보고, 국내 성인남녀 603명을 대상으로 집회시위에 대한 시민의식 조사결과의 분석을 통해 실질적인 대안을 제시하고자 한다. 설문지를 통해 수집한 집회시위 현장에서 경찰법집행에 대한 국민의 인식과 수용도제고를 위한 의견을 수렴에 대한 데이터를 분석한 결과 전반적으로는 한국국민의 집회시위시 경찰 법집행에 대한 인식은 긍정적인 인식과 부정적인 인식이 절반정도를 차지하고 있으며 과거와 다른 점은 집회시위 현장에서 법을 준수하고 경찰의 통제에 따르는 것이 손해를 보는 것이 아니라는 의견이 80%에 달하고 있으며 경찰의 법집행이 일관성을 가지고 있다는 의견이 60%이상, 경찰이 집회시위 관리를 잘하고 있다고 생각하는 경우가 50%이상으로 과거에 비해 경찰의 집회시위에 대한 시민의 인식이 긍정적으로 변화되고 있음을 감지할 수 있었다. 다만, 아직도 경찰이 집회시위 현장에서 인권을 존중하지 않는다는 견해가 60%이상이며 집회시위 현장에서의 경찰의 법집행에 우선적으로 수용해야 한다는 인식이 전연령대, 전지역별로 고르게 70%이상 높게 나타나고 있다. A rally or demonstration is action by a mass group or collection of groups of people in favor of a political or other cause; it normally consists of walking in a mass march formation and either beginning with or meeting at a designated endpoint, or rally, to hear speakers. In U. K., under the Serious Organised Crime and Police Act 2005 and the Terrorism Act 2006, there are areas designated as "protected sites" where people are not allowed to go. Previously, these were military bases and nuclear power stations, but the law is changing to include other, generally political areas, such as Downing Street, the Palace of Westminster, and the headquarters of MI5 and MI6. Previously, trespassers to these areas could not be arrested if they had not committed another crime and agreed to be escorted out, but this will change following amendments to the law. In U. S., the First Amendment of the United States Constitution specifically allows peaceful demonstrations and the freedom of assembly as part of a measure to facilitate the redress of such grievances. A growing trend in the United States has been the implementation of "free speech zones," or fenced-in areas which are often far-removed from the event which is being protested. In Korea, ordinary citizens’ political rallies or protests after sunset and before sunrise are prohibited by law. The 2008 US beef protest in South Korea was a series of demonstrations which occurred between 24 May 2008 and about 18 July 2008 in Seoul, Korea involving, at its height, tens of thousands of people.
This work was carried out to obtain sound welds and to select a most suitable binary metal joint among three different dissimilar binary metal combinations such as Zr-4/Ta, Mo/Ta and Ti/Ta(seal tube/sensor sheath) joints fur the instrumented nuclear fuel irradiation test. To do this, Taguchi experimental method was employed to optimize the experimental data. In addition, metallography, micro-focus x-ray radiography and hardness test were conducted to examine the welds. From the weld bead appearance, penetration depth and bead width as well as weld defects standpoint, Zr-4/Ta joint is suggested for the circumferential joining between a seal tube and a sensor sheath. The optimized welding parameters based on Zr-4/Ta joint are suggested as well.
Using Korean Mental Power Questionnaire and Self-Esteem Scale with a sample of 218(male; 143, female; 75) Taekwon-do players, this study examines the variation of mental power according to the levels of age, efforts, self-esteem and also investigates the relationship between self-esteem and mental power of Taekwon-do players. Findings: Junior high players show higher Fighting spirit and competitiveness than high school Taekwon-do players. There is a significant difference according to the level of efforts, especially players with higher levels of efforts to practice demonstrate higher level of mental powers on every sub-variables like fighting spirit, efforts, endurance, competitiveness. Moreover, players with high self-esteem tend to have higher mental power. Lastly, based on regression analysis, the mental power variables are predictive of player`s self-esteem explaining 69% of total variance. Particularly competitiveness shows the most significant effects and the next significant variables, in the order of strength, are fighting spirit, endurance, hard effort. This study is based on previous researches and theories and provides implication on the importance of mental exercise.
