In a recent mobile computing environment, the research for a transaction model have been actively carried out to deal with real-time transaction. However, the research for recovery model is relatively insufficient. Therefore, it would be very important for mobile recovery methods for database stability, just in case of data loss due to hand-off in mobile computing system. So, further efficient research should be keenly done to reduce I/O hand-off in mobile computing systems. SLL method increases I/O time due to sequential file. This paper have been suggested to efficient mobile recovery method in mobile computing system. Finally, it has been clearly demonstrated for system efficiency, conducting the performance assessment that currently proposed recovery system.

Abstract. The purpose of this study was to understand the effects of youths' general characteristics on their emotional intelligence and self-esteem. For this study, 150 youths from youth education institutes located in Ulsan were selected and the assessment of the pertinent youths' emotional intelligence and selfesteem was conducted by their teachers. For the data analysis, the SPSSWIN 18.0 program was used to conducted frequency analysis, t-test, one-way variance analysis, correlation analysis, and multiple regression analysis and the proof analysis was verified at the significance level of 5%. The result of the analysis was as follows. First, it was shown that the difference in youths' emotional intelligence depending on their general characteristics was significant. Second, it was shown that the difference in self-esteem depending their general characteristics showed significance following in the order of sex and date of birth. Third, it was shown that there is a high correlation between youths' emotional intelligence and self-esteem. The results of this study is expected to propose the direction for the healthy and positive development of self-esteem and emotional intelligence and become basic academic data.
