This study determines what affects the academic achievement of senior high school students in the context of the individual, family, and school environment. The sample selection consisted of 1484 high school seniors in Korea. The following are the results of this study: First, female students scored higher in academic achievement than male students. Second, academic achievement by male students was related to levels of school satisfaction, academic motivation, and family strength, while academic achievement by female students was related to levels of parents' education, family income, ego-resiliency, school satisfaction, academic motivation, and family strength. Third, the most important predictor of academic achievement for male and female students is academic motivation, followed by school satisfaction. The present study highlighted the necessity to develop academic achievement improvement programs appropriate for both genders of senior high school students.

This paper investigates the performance improvement opportunities through a resiliency mechanism in the distributed primary/backup database system. Recognizing that a distributed transaction executes at several servers during its lifetime, we propose a resiliency mechanism which allows continuous transaction processing in distributed database server systems in the presence of a server failure. In order to perform continuous transaction processing despite failures, every state change of a transaction processing can be saved in the backup server. Obviously, this pessimistic synchronization may give more burdens than benefits to the system. Thus, the tracking needs not be done synchronously with the transaction progress. Instead, the state of all transaction processing in a system is saved periodically. This activity is referred to as a savepoint. Then, the question is how often the savepoint has to be done. We derive the optimal savepoint to identify the optimization parameters for the resilient transaction processing system.

In this paper, we introduce a grid-based key pre-distribution scheme in wireless sensor networks, which aims to improve the connectivity and resiliency while maintaining a reasonable overhead. We consider simplification of the key establishment logic and enhancement of the connectivity via plat polynomial assignment on a three-dimensional grid for node allocation and keying material assignment. We demonstrate that our scheme results in improvements via a detailed discussion on the connectivity, resource usage, security features and resiliency. A comparison with other relevant works from the literature along with a demonstrated implementation on typical sensor nodes shows the feasibility of the introduced scheme and its applicability for large networks.

This paper presents an improved redundant picture coding method that efficiently enhances the error resiliency of H.264. The proposed method applies polyphase downsampling to residual blocks obtained from inter prediction and selectively encodes the rearranged residual blocks in the redundant picture coding process. Moreover, a spatial-temporal sample construction method is developed for the redundant coded picture, which further improves the reconstructed picture quality in error prone environments. Simulations based on JM11.0 were run to verify the proposed method on different test sequences in various error prone environments with average packet loss rates of 3%, 5%, 10%, and 20%. Results of the simulations show that the presented method significantly improves the robustness of H.264 to packet loss by 1.6 dB PSNR on average over the conventional redundant picture coding method.

The aim of this survey has been to investigate the effects of positive psychological capital of students from some universities in Busan and Ulsan on communication skills and interpersonal skills. As a result of the relationship with the main variables, there was a significant positive correlation between sub-factors of positive psychological capital and each ability. Hope(p<0.01) and Resiliency(p<0.05) among the effects of positive psychological capital on communication skills were statistically significant, and, in case of those on interpersonal skills, Resiliency(p<0.001), Efficacy(p<0.05), and Hope(p<0.05) were statistically significant. Therefore, it is necessary to develop and apply an intervention program that can establish the importance of positive psychological capital and strengthen positive psychological capital in order to improve students' communication and interpersonal skills.

In this paper, we suggest new fast recovery mechanism in RPR network, in case of node addition or removing by exterior attack. A RPR network recovery time is consist of two. Failure detecting time and reporting time are that. In this paper we propose fast recovery mechanism that can reduce each time. In a Legacy recovery mechanism, To report node's state, rpr node transmit protection messages. But interval of this protection messages increase exponentially. Thus A transmission failure of protection message cause delay of reporting of network state. Therefore we propose new node state reporting mechanism that put a node state in type b fairness message. And We also suggest fast failure detecting mechanism.

The purpose of the study was to identify the factors influencing the nursing students' job-seeking stress. A cross-sectional descriptive survey, using a structured questionnaire, was used to collect data from Sep. to Oct. 2016. A sample of convenience was 246 nursing students and a questionnaire was used to measure their major satisfaction, CDMSE, self-esteem, ego-resiliency, and job-seeking stress. A significant negative correlation was found among job-seeking stress, major satisfaction, CDMSE, self-esteem, and ego-resiliency. Grade of which the participant was in, self-esteem, academic achievement, experience of clinical practice, and family economic status were significant predictive variables of which accounted for 46.1% of the variance in job-seeking stress. The results from this study can be used to develop programs for job-seeking stress management.

The purpose of this study is to investigate the relationship between emotional intelligence and convergence factors of hospital administrative staff. During the survey period from From May 1st to May 31st, 2019, anonymous self-administered responses to 212 administrative staffs of 19 hospitals randomly selected in J area were used as analysis data. According to hierarchical multiple regression analysis, the higher the ego-resiliency, the higher the organizational loyalty, and the higher the organizational commitment, the higher the emotional intelligence, and their explanatory power was 43.0%. Based on these analysis results, efforts are needed to increase ego-resiliency, increase organizational loyalty, and increase organizational commitment in order to increase the emotional intelligence of hospital administrative jobs. The above results are expected to be applied to industrial health education and job management in the future at hospitals to enhance emotional intelligence of hospital administrative staffs. Future research requires the establishment and analysis of a structural equation model that affects the emotional intelligence of hospital administrative staffs.

The purpose of this study is to analyze the structural relationship, direct and indirect effects between adolescents' peer attachment, self-resilience, academic stress, and smartphone addiction. The subject of this study used panel data of a total of 1280 middle school students who participated in the 14th study of the Children's Panel of the Korea Child Care Policy Institute. For data analysis, SPSS 24.0 and AMOS 24.0 programs were used. As a result of the study, children's peer attachment was positively correlated with ego resiliency, academic stress and negatively correlated with smartphone addiction. All pathways except peer attachment and smartphone addiction were found to have a direct influence, and adolescents' peer attachment had an indirect effect on smartphone addiction through ego resiliency and parental achievement pressure. In conclusion, in order to lower adolescents' smartphone addiction, practical interventions to improve ego resiliency and reduce academic stress through peer attachment are considered necessary.
