This is a correlational study analyzing the relationship between burden and qualify of life in mothers of mentally retarded children. The subjects for this study were 104 mothers of retarded children at a retarded welfare center, early training of retarded children rehabilitation center, and retarded school in Kwangju. Data were collected from 1st Feb. to 27th Feb, 1998. The instruments used for this study were the burden scale developed by Seo, and the quality of life scale developed by Yang. The data were analyzed by the t-test, ANOVA, and Pearson's Correlation Coefficient using SPSS. The results of this study were as follows : The mean score of burden:3.08, The mean score of quality of life: 2.60, The mean score of subscale : family relationship: 3.20, self-esteem and general life; 3.08, friends and relationships; 2.70, physical and psychological health; 2.56, economical life (cloths. food) ; 2.52, job and daily work; 2.27, recreation, 2.07, recreation, job and daily work scored lowest. The analysis of the level of burden according to general characteristics of the subjects showed statistically significant differences in husband's help (F=4.21, p=.018), and the degree of retardation in the children(F=13.67, p=.000). The 1st hypothesis, "e mothers' burden differed according to the degree of their children's MR"as supported. The analysis of qualify of life according to general characteristics of the subjects showed statistically significant differences in living state(t= 2.19, p= .031) , the health state of mothers(F=4.17, p= .018), husband's help(F= 11.55, p= .000) , and the degree of retardation in the children(F=3.76, p= .013). The 2nd hypothesis, "e mothers' quality of life differed according to the degree of their children's MR"as supported. The correlation between burden and quality of life was statistically significant(r=-0.562, p=.000). The 3rd hypothesis, "e lower the level of burden, the higher the quality of life" was supported. In conclusion, it was found that the lower the level of burden is, the higher the quality of life becomes.

System utilization is enhanced by an allocation scheme with a good submesh recognition capability, but its merits are degraded by the mesh external fragmentation. Even when the system is saturated at high system load, the system utilization is lower than 60% for the previously proposed schemes. This is due to the fact that the FCFS task scheduling policy leads to large external fragmentation. Although various researches related to the submesh allocation have gone to great lengths to improve the submesh recognition capability, few solutions to the fragmentation problem have been proposed. In this paper, we propose an efficient task scheduling scheme to solve the fragmentation problem in a mesh connected systems. Simulation results show that the proposed strategy improves the performance compared to the FCFS scheduling policy.

While a better submesh allocation scheme can improve system performance, an allocation policy alone cannot improve performance significantly. This is due to the fact that the FCFS task scheduling policy leads to large external fragmentation. In this paper, we propose an efficient task scheduling scheme, called CTS(Class-based Task Scheduling) scheme, to improve the system performance by solving the fragmentation problem in mesh connected systems. Simulation results indicate that the proposed scheduling strategy improves the performance compared to the FCFS scheduling policy by reducing the average waiting delay significantly.

목적 : 본 연구는 ESBL을 생성하는 K. pneumoniae에 의한 균혈증 환자에서 감염의 위험 인자 및 치료 결과를 알아보고자 시행하였다. 방법 : 1998년 1월부터 2002년 4월까지 혈액 배양 검사에서 동정된 K. pneumoniae를 대상으로 NCCLS guidelines과 이중 디스크 확산법(double-disk diffusion test)을 이용하여 ESBL 생성 여부를 확인하였다. ESBL 생성 균주에 의한 균혈증 환자 60명(환자군)에 대해 ESBL을 생성하지 않는 균주에 의한 균혈증 환자들(대조군)을 연령, 성별, 균혈증 발생 시점을 고려하여 1:2 또는 1:3으로 배정하였다. 총 159명의 대조군을 선정하였고 후향적인 환자-대조군 연구를 시행하였다. 결과 : 환자군과 대조군 사이에 연령, 성별, APACHE Ⅱ score, 주된 감염 부위의 유의한 차이는 없었다. ESBL을 생성하는 K. pneumoniae에 의한 균혈증이 발생할 독립적인 위험 인자에는 요관 삽입, 균혈증 발생 이전 72시간 동안 침습적인 시술을 받은 경우, 균혈증 발생 이전 30일 동안 투여받은 항생제 개수가 있었다. 초기 항생제 치료 72시간 후의 반응을 평가하였을 때, 완전 반응(complete response)은 대조군에서 더 많았고(13.3% vs. 40.3%, P<0.001), 치료 실패(treatment failure)는 환자군에서 더 많았다(33.3% vs. 11.9%, P<0.001). 7일 사망률은 환자군에서 20% (12/60), 대조군에서 15.6% (25/159)이었고(P=0.451), 30일 사망률은 환자군에서 30% (18/60), 대조군에서 24.5% (39/159)이었다(P=0.410). ESBL 생성 균주에 의한 균혈증이 있는 환자들에서 최종 항생제 치료가 부적절했던 환자들을 제외하고 30일 사망률을 분석하였을 때 효과적인 항생제 치료의 지연은 사망률을 높이지 않았다(11.1% vs. 9.1%, P=1.000). 결론 : ESBL을 생성하는 K. pneumoniae에 의한 균혈증이 있는 환자에서 초기 항균제 치료 72시간 후의 치료 반응률은 낮지만 사망률은 유의하게 증가하지 않았다. 원인균이 동정된 후 최종 치료 항생제의 선정이 적절하다면 초기에 효과적인 항생제 투여의 지연은 사망률을 유의하게 증가시키지는 않았다. Background : This study was conducted to evaluate risk factors for infection and treatment outcome of bloodstream infection due to extended spectrum β-lactamases(ESBL)-producing K. pneumoniae. Methods: ESBL production was evaluated by NCCLS guidelines and/or double-disk synergy test in K. pneumoniae blood isolates stored from January, 1998 to April, 2002. Sixty patients with bloodstream infection due to ESBL-producing K. pneumoniae (case patients) were compared with 159 matched control patients with bloodstream infection of non-ESBL-producing K. pneumoniae. Retrospective case-control study was performed. Results : There were no significant differences in age, sex, APACHE Ⅱ score, and the primary site of infection between the case and control groups. In multivariate analysis, significant independent risk factors associated with bloodstream infection due to ESBL-producing K. pneumoniae were urinary catheterization, invasive procedure within previous 72 hours, and the number of antibiotics administered within previous 30 days. In clinical response at 72 hours after initial antibiotic treatment, complete response rate was higher in the controls (13.3% vs. 40.3%, respectively, P<0.001), however, treatment failure rate was higher in the cases (33.3% vs. 11.9%, respectively, P<0.001). Overall 7-day mortality rates in the cases and the controls were was 20% (12/60) and 15.7% (25/159) (P=0.451), respectively, and overall 30-day mortality rates were 30% (18/60) and 24.5% (39/159), respectively (P=0.410). When the patients with bloodstream infection of ESBL-producing organism were evaluated and the patients who received inadequate definitive antibiotic treatment were excluded, delayed effective antibiotic treatment was found to be not associated with higher mortality. Conclusion : In patients infected with ESBL-producing K. pneumoniae bacteremia, clinical response rate at 72 hours after antimicrobial therapy was lower, but the increase of mortality rate was not significant. Delayed effective antibiotic treatment was not associated with higher mortality, when definitive appropriate antibiotic treatment was prescribed.

워크스테이션 네트워크에서 통신과 연산 비용의 효과

강오한 安東大學校 工業技術硏究所 2000 공업기술연구논문집 Vol.7 No.1

워크스테이션 네트워크(NOW: Network of Workstations)은 고성능의 병렬 연산을 위한 중요하고 효과적인 기반환경으로 나타나고 있다. NOW에서 스케줄링 기법의 선택은 시스템의 활용도와 성능에 큰 영향을 미치므로 병렬 태스크와 통신을 효과적으로 스케줄링해야 한다. NOW환경에서 통신과 동기화 비용은 다중프로세서 시스템보다 상대적으로 매우 크다. 이 논문에서는 NOW에서 병렬 태스크간의 통신 상호작용에 따른 성능에 대한 영향을 분석한다. Network of Workstations (NOW) has emerged as an important and cost-effective platform for high performance parallel computing. Scheduling of parallel tasks and communications of NOW is important because the choice of a scheduling discipline can have a significant impact on the utilization and performance of the system. On a NOW environment, communication and synchronization costs are relatively high compared with multiprocessor systems. In this paper, we examine the effect of communication interactions between parallel tasks on NOW.

In this paper, we propose a new task migration scheme, called CSC(Complement Subcube Coalescence) strategy, to solve the fragmentation in a hypercube. Since allocation and deallocation of the subcubes usually result in a fragmented hypercube, the fragmentation problem should be solved by a task migration. Specifically, we developed a task migration scheme for the SIG strategy because the procedure for the task migration is closely related to the subcube allocation scheme. Extensive simulation results show that the CSC strategy improves the efficiency and reduces the response time significantly with a lower migration cost compared to previously proposed schemes.
