  • 버스 시스템은 하나의 버스 내에 여러 개의 마스터와 슬레이브, 아비터 그리고 디코더로 구성되어 있다. 마스터는 CPU, DMA, DSP 등과 같은 데이터의 명령을 수행하는 프로세서를 말하며, 슬레이브는 SRAM, SDRAM, 레지스터 둥과 같이 명령에 응답하는 메모리를 말한다. 또한 아비터는 마스터가 동시간대에 버스를 이용할 수 없기 때문에 이를 중재하는 역할을 수행하는데, 어떠한 중재 방식을 선택하는가에 따라 버스 시스템의 성능이 크게 바뀔 수 있다. 일반적인 중재 방식에는 fixed priority 방식, round-robin 방식이 있으며, 이를 개선한 TDMA 방식과 Lottery bus 방식 등이 현재까지 제안되었다. 본 논문에서는 새로운 중재 방식인 스코어 중재 방식을 제안하고 이를 TLM 알고리즘으로 구성하여 일반적인 중재방식과 시뮬레이션을 통해 성능을 비교 분석하였다. 앞으로의 버스 중재 방식은 스코어 중재 방식을 기초로 더욱더 발전할 것이며, 버스 시스템의 성능을 향상시킬 것이다.

  • A serious disease in a family influences the entire family member given the fact that the members closely interact with each other. Especially in terms of pediatric nursing, study on family gains importance as the need to care of families whose children with developmental disabilities and chronic disease This study was done based on The Resiliency Model of Family Adjustment and Adaptation(McCubbin, 1991) is intended to examine the stress of parents whose children suffer from cleft lip or /and cleft palate. It also helps them to cope with the stress and analyze the relationship between the stress and coping This study used Family Inventory of Life Events and Changes (FILE) and Coping Health Inventory for Parents(CHIP) for measuring family stress and coping. The two instruments are revised to fit the social and cultural environment of Korean culture. Data collection was done from April 18, 1996 to May 18, 1996 at 8 University medical centers located in Seoul. Those who answered questionnaires were 84 parents whose children have cleft lip or /and cleft palate. SPSS PC+ was used to analyze the data collotted. Programs used for data analysis were t-test, ANOVA, Pearson correlation coefficient. The study is summarized as follows .1. The average score of family stress is 10.46(percentage of the full score 24.90) and 'finance and business strains'(3.25), and 'intrafamily strains'(2.65) ranked the highest. The average score of family's coping is 1.93, which is close to the answer of' moderately helpful' and they are measured to put their utmost efforts to' intergration and cooperation of family and optimistic definition on the situation'. 2. There is no significant statistical correlation between the family stress and coping. 3. Mothers show more stress than fathers in the parts of 'illness and family care strains' and 'losses'(t〓-2.34, t〓-2.32, p<.05). 4. Fathers show more willingness to cope with the stress than mothers do in the parts of' seeking social support','self-esteem','emotional comfort' 5. Mothers are more stress than fathers in the parts of family stress and its coping with it by usual traits(t〓-2.78, p<.05). Parents with religion are measured to cope more willingly than those who are not 6. Income of a family shows positive correlationship with family coping (r〓.28, p<.05). The study shows that gender difference is significant variable in studying on family stress and coping. Mothers get more stress than fathers, which has much to do with the fact that they are in charge of raising children and keeping houseworks. Accordingly, managing family crisis and its survival can be induced by giving support for the mothers, studying fathers including the rest of the family members and giving nursing care and arbitration ; religious background is also considered to be one of the important factors in family stress , judging from the relationship between family income and family's coping, caring given to suffering children is needed on societal levels. The above considerations bring up the need to have a longitudinal study of children with congenital anomaly including cleft lip or /and cleft palate and their families about family stress and coping. Resiliency programs on family system and their effectiveness and the relationship between the enlarged families with social and cultural values reflecting Korean tradition are also needed to be studied.
