한국 청소년의 균형 잡힌 민주시민역량을 조성하기 위한 지원체계 개발을 위하여 청소년이 이용하는 도서관에 주목한 연구는 희소하다. 본 연구는 청소년 민주시민역량 수준에 도서관이용이 어떠한 영향을 미치고 있는지 경험적 검증을 시도하고 그 결과의 공공정책적 함의를 모색하였다. 본 연구는 2006년 한국청소년정책연구원이 표집한 중 고등학교 1~3학년 재학생 1,386명의 표본자료 분석을 통하여 도서관 이용자들과 비이용자들 간의 민주시민역량 수준의 차이 검정과 도서관이용 경험이 민주시민역량 수준에 미치는 영향을 알아보기 위한 다중회귀분석을 실시하였다. 청소년의 도서관이용 경험은 인식적 민주시민역량에는 긍정적 효과를, 실천적 민주시민역량에는 부정적 효과를 미치고 있었다. 이를 토대로 한국 청소년의 균형적 민주시민역량 조성을 위한 지원체계의 설계와 관련하여 도서관정책 관련 제언을 하였다. The present study tests the effects of library use on adolescents' civic competencies for democratic citizenship in a Korean context. Utilizing data (N=1,386) from the National Youth Policy Institute (2006), the study performed multiple regression analyses to test the association of library use of adolescents with the levels of civic competencies for democratic citizenship. Teenagers' library use had a positive significant association with cognitive civic competencies while showing a negative significant association with behavioral dimension of civic competencies. Based on the findings, the author discusses policy implications for developing library service for youth.

본 연구에서는 다변량시계열모형인 VAR (vector autoregressive regression)모형에 의하여 금리 스프레드의 시계열예측을 수행하였다. 국내외 거시경제변수들 중에서 교차상관분석 및 그랜져인과 검정을 통하여 상호간에 설명력이 있는 변수들을 추출하여 VAR모형의 시계열변수로 사용하였다. 마지막 12개월의 예측치에 대한 MAPE (mean absolute percentage error)와 RMSE (root mean square error)에 근거하여 모형의 예측력을 단일변량 시계열모형인 AR (autoregressive regression) 모형과 비교하였다. In this paper, we predicted the interest spread using the VAR (vector autoregressive) model. Variables used in the VAR model were selected among 56 domestic and foreign macroeconomic time series through crosscorrelation and Granger causality test. The performance of the VAR model was compared with the univariate time series model, AR (autoregressive) model, in view of MAPE (mean absolute percentage error) and RMSE (root mean square error) of forecasts for the last twelve months.

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.

N/A Ultrafiltration failure has been known as a major cause of dropout from long-term peritoneal dialysis and is often related to peritoneal hyperpermeability. This can be explained in part by progressive peritoneal fibrosis. The present experiment has been under- taken to evaluate the effects of peritoneal rest on peritoneal transport and morphology in rat model of peritoneal dialysis. Twenty-four male rats(Sprague-Dawley, 250-300g) were used and divided into three groups : group 1 (control, n=6) without dialysis, group 2(n=9) sacrificed immediately after 3 weeks of dialysis, and group 3 (n=9) sacrificed after 4 weeks of peritoneal rest after 3 weeks of dialysis. Peritoneal dialysis was performed twice a day with 25mL of 3.86% dextrose solution for 3 weeks. Peritonitis was induced by supplementing lipopolysaccharide(5μg/mL) in the dialysis fluid on days 8, 10 and 12 of peritoneal dialysis. Peritoneal equilibration tests were performed before dialysis and repeated on the 4th and 8th week of dialysis. Mor-phometric analysis of the peritoneal membrane and immunohistochemistry for collagen type I and type III were done in tissue specimens obtained at the time of sacrifice. The D/Do ratio for glucose at two hours in groups 2 and 3 at the beginning of week 4 were signifi-cantly lower than baseline value, indicating increase in the peritoneal penneability to glucose after 3 weeks of dialysis. D/Do in group 3 at the beginning of week 8, after 4 weeks of peritoneal rest, was significantly higher than at week 4. The drained dialysate volumes in groups 2 and 3 at week 4 were significantly lower than at baseline; however, The drained dialysate volume in group 3 at week 8 was significantly greater than at week 4. The thickness of the parietal peritoneal membraoe in group 2 and 3 were significantly greater than in group 1. Severity of the thickness of the parietal peritoneal membrane in group 3 was not much than that of group 2(group 1, 11.4±7.6; group 2, 37.5±18.4; group 3, 21.4±12.1 pm). Histologically, the thickened peritoneum in group 2 showed a monolayer of mesothelial cells and under-lying multilayer of curled collagen bundles. Mononu-ciear cells and fibroblasts were embedded in these collagen layers and capillary proliferation was present. Immunohistochemistry for collagen type I and Z demonstrated that the distribution of collagen type llI was richer than that of collagen l in group 2 at fibrotic area of submesothelial region. These findings were decreased in group 3. Ultrastructural examination of the peritoneum showed thicker fibrotic zone and the activated fibro-blasts in group 2 compared to group 1 and 3. Meso-thelial cells were plump and the number of meso-thelial microvilli was decreased in group 2. Nucleus was enlarged and irregular. Intracytoplasmic orga-nelles were also richer than those of group I or 3. In conclusion, peritoneal rest improves ultrafil- tration in rats by decreasing the hyperpermeability of glucose and also reduces the degree of peritoneal fibrosis. These data suggest that dialysis-induced changes in peritoneal transport and morphology are reversible under the condition of peritoneal rest in this experimental model.

A robot manipulator sharing its workspace with humans must be designed in consideration of human safety. Safety can be achieved by either a passive or active compliance system. With an active system. it is possible to react against the collision in a more sensitive manner. We propose the collision detection algorithm with current information using a fault detection and isolation scheme. This algorithm needs friction compensation when the inertial factor of the system is smaller than the usual one. Experiments were conducted using a one-link manipulator. The experimental results show that the proposed system can detect collision while a manipulator is moving even under the acceleration. which can improve collision safety.
