Intermittent failures exercise their effects only part of the time but constitute a dominant factor for the field failures. We consider the data raliability of the partially self-checking network with which a single intermittent failure will be recovered by a rollback method. Even if the self-testingness of partially self-checking network is guranteed for a set of permanent failures, it sometimes may not be so for intermittent failures. We introduce the notion of error residual and provide the basis for calculating the data reliability. Both the duration of each intermittent failure and the occurrence interval of successive ones are assumed to be negative exponentially distributed; the convolution of the intervals is distributed according to an Erlangen distribution.

Purpose: This study examined the correlation between satisfaction with major, academic self-efficacy, and academic persistence with the general characteristics of students in a health-related field, to determine factors that affect academic persistence. Methods: The study was conducted on third- and fourth-grade health-field students at Daejion. The questionnaire consisted of a self-report, and a URL was sent by text message to students who agreed to participate after reading the purpose and necessity of the study. Results: Major satisfaction was 4.23 on average, academic self-efficacy was 4.15, and academic continuity was 4.25. Grade and school life satisfaction were the factors correlated with a significant difference in academic persistence. Significant positive correlations were seen between satisfaction with major (r=.637, p<.001) and academic self-efficacy (r=.563, p<.001); higher major satisfaction and academic self-efficacy led to higher academic persistence. Conclusion: A more systematic management approach needs to be conducted by developing active learning participation and applying customized counseling management and support programs by grade to improve the academic self-efficacy and academic persistence of students in health-related fields.

This study aims to investigate hypotheses for the effects of CEO's self-sacrificial leadership behaviors and employee's organizational committment of 50 Korea venture firms registered in Korea Venture Business Associations. To understand the importance of followers' characteristics in recent leadership studies on venture CEOs, it is proposed that self-sacrificial leadership behaviors will positively effect on organizational commitment. And it is also proposed that the follower's need for achievement(N-Arch) moderates in the relationship of self-sacrificial leadership behaviors and organizational commitment. After descriptive survey, research model setup, and field survey, this empirical study investigated the above mentioned hypotheses thru SPSS for Windows 12.0. It involved linear regression analysis to reveal the significant main effect of the self-sacrificial leadership behaviors. It also revealed moderating regression analysis to reveal the significant moderating effects of need for achievement between the independent variables(self-sacrificial leadership behaviors) and dependent variable(the organizational commitment). Results revealed that CEO's self-sacrificial leadership behaviors positively affected to its employee's organizational commitment under change-oriented and innovative new technology drive, self-developing environments of venture business in Korea. However, positive moderating effect of N-Arch was not supported between leader's self-sacrificial leadership behaviors and follower's organizational commitment in Korea venture firms.
