  • Mixed-criticality systems consist of components with different criticality. Recently, components are categorized depending on criticality by ISO 26262 standard and DO-178B standard in automotive and avionic domain. Existing mixed-criticality system research achieved efficient and safe scheduling through system-level criticality mode. The drawback of these approaches is performance degradation of low-criticality tasks on high-criticality mode. Task-level criticality mode is one method to address the problem and improve the performance of low-critical tasks. In this paper, we propose probabilistic performance metric for the approach. In simulation results with probabilistic performance metric, we showed that our approach has better performance than the existing approaches.

  • A new rose cultivar, 'Green Beauty' was selected from the progenies of a cross between 'Qvarna' and 'Sky Line' by rose breeding team of the Gyeonggi-Do Agricultural Research and Extension Services in 1999. It was finally selected in 2005 after evaluation trials for five years (2001-2005). 'Green Beauty' was developed for a standard-type cut flower. 'Green Beauty' has good qualified flower of which color is fair orange-yellow and green. 'Green Beauty' produces $178stems/m^2$ in a year, and has 62 petals per flower. Vase life of the cultivar could be as long as 12 days. 'Green Beauty' has some good agricultural and marketing traits. Futhermore marketing-quality was good in some aspects. The cultivar was applied for a variety protection in 2006, and was released to commercial growers in 2007.

  • This study was analyzed to job satisfaction of 318 Instructors who are teaching HapKiDo, a martal art. The analysis is based on social and economic variables such as age, occupation, educational background, income, size of gymnasiums, the number of students, a length of training and the rank of skills (DAN). The study also made some helpful suggestions for better treatment to HapKiDo Instructors. To explore Instructors degree of satisfaction with their jobs. I considered their human relationship, job task, working conditions, compensation, the improvement of professionalism and social status. The study drew some important results.: First, Job satisfaction in terms of human relationship is very high(3.88). wheres the satisfaction in terms of compensation is very low(3.10). Second, the differences in job satisfaction were partially significant in terms of human relationship, job tasks, working conditions, compensation, the improvement professionalism and social status.

  • A few bioinformatics tools have been used to find out conserved regions as probes. We have developed a system based on a heuristic method with web interfaces to find out conserved regions against microbial genomes. The system runs in real time by using relative entropy in limited narrow regions and detecting similar regions between pair regions with local alignment. The system could be useful to find out conserved regions as genome-wide scale.
