  • Bus system consists of several masters, slaves, arbiter and decoder in a bus. Master means the processor that performs data command like CPU, DMA, DSP and slave means the memory that responds the data command like SRAM, SDRAM and register. Furthermore, as multiple masters can't use a bus concurrently, arbiter plays an role in bus arbitration. In compliance with the selection of arbitration method bus system performance can be charged definitely. Fixed priority and round-robin are used in general arbitration method and TDMA and Lottery bus methods are proposed currently as the improved arbitration schemes. In this stuff, we proposed the score arbitration method and composed TLM algorithm. Also we analyze the performance compared with general arbitration methods through simulation. In the future, bus arbitration policy will be developed with the basis of the score arbitration method and improve the performance of bus system.

  • Objectives: This research aimed to identify the level of perception, knowledge, preventive behavior, and factors affecting preventive behavior of patients with asthma and chronic obstructive pulmonary disease against particulate matter. Methods: This research was a descriptive survey research, and the subjects were chronic pulmonary disease patients over the age of 19 and under 80 who visited a university hospital in Daegu City. Data was collected by convenience sampling through structured self-administered questionnaire survey from December 2019 to January 2020, and a total of 212 copies were used for analysis. Results: Out of 212 total subjects, 112 were asthma patients (52.8%) and 100 were chronic obstructive pulmonary disease patients (47.2%). The average score (out of 10) of perception, knowledge and preventive behavior of patients with asthma for particulate matter was 7.92, 6.99, and 7.10, respectively, while those with chronic obstructive pulmonary disease scored 7.72, 6.24, and 6.80, respectively. The knowledge score was significantly higher in patients with asthma than those with chronic obstructive pulmonary disease (p=0.007). Factors affecting particulate matter preventive behavior were perception score, knowledge score, and age for asthma patients, and perception score for chronic obstructive pulmonary disease patients. Conclusions: As a result of the above, the factors relate to the preventive behavior of patients with asthma and chronic obstructive pulmonary disease were perception score, knowledge score, and age for asthma, and perception score for chronic obstructive pulmonary disease. Raising the level of particulate matter preventive behavior can prevent the deterioration of chronic pulmonary diseases caused by particulate matter, so the development of arbitration programs considering the characteristics of the patients according to the disease and continuous and repetitive education are required.

  • 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.
