Despite the benefits of social activity on happiness, humans still spend over one third of their time by themselves-sleeping. The effect of sleep quality on happiness as well as its underlying mechanism are examined in this study. Based on previous findings on the role of sleep in consolidation of memories, it was hypothesized that a good sleep would promote happiness by increasing the likelihood of recalling everyday episodes in a positively biased manner. In Study 1, regardless of one's demographic variables, social variables, and economic status, sleep quality was positively related to life satisfaction. To examine the causal direction of this effect, participants were asked to complete a survey twice with different time intervals. Controlling for baseline variables, sleep quality during previous two weeks (Study 2) or previous day (Study 3) significantly predicted the participants' life satisfaction. Moreover, this relationship was partially mediated by a positive memory bias (Study 3). This study opens interesting questions on a relatively unexamined nonsocial predictor of happiness, sleep quality.

The purpose of this study is to empirically verify the effects of positive psychological capital on participation in lifelong learning as well as the mediating effect of self-directedness of adult learners in Korea. The research model was constructed using positive psychological capital as an independent variable, lifelong learning participation performance as a dependent variable, and self-directedness as a mediating variable. The results of the study are as follows: First, positive psychological capital of adult learners has a significant effect on self-directedness and participation in lifelong learning. Second, self-directedness has a significant effect on participation in lifelong learning. Third, self-directedness plays a mediating role between positive psychological capital and participation in lifelong learning. The results of this study indicate that positive learning psychology and self-directedness are important factors for participation in lifelong learning. The results of this study are expected to contribute to the development of lifelong learning systems and the development and operation of programs that can enhance positive psychological capital and self-directedness of adult learners.

For this purpose, the program to improve the positive psychological capital was carried out a total of 6 times (90 minutes per session) once a week for 24 university students at "C"university located in Gangwon-do, which was divided into 2 groups. In this study, the data were collected through a pretest and a posttest and, data analysis was performed using SPSS 20.0 ver. Based on the results, the program to improve the positive psychology capital was effective in increasing the positive psychology capital. Finally, the implications of the results, as well as the significance and limitations of the present study are discussed.

This study aimed to identify the effect of resilience and positive psychological capital on hospital nurses' professional quality of life. A cross-sectional survey design was utilized to investigate 221 general hospital nurses from June 1 to 30, 2021. Professional quality of life (ProQOL), which is conceptualized with three sub-dimensions (compassion satisfaction, burnout, and secondary traumatic stress), resilience, and positive psychological capital variables were measured. There was a positive relationship between compassion satisfaction and resilience, positive psychological capital, and a negative relationship among burnout, secondary traumatic stress, and the other variables in this study. The main factors influencing compassion satisfaction were resilience, and positive psychological capital, which explained about 47% of compassion satisfaction. Burnout was influenced by resilience, positive psychological capital, and work pattern, and these variables explained about 37% of burnout. Notably, it was found that resilience was the most crucial factor in nurses' compassion satisfaction, and positive psychological capital was the most crucial factor in nurses' burnout. Thus, it is suggested to develop and verify the effectiveness of a resilience improvement program and positive psychological intervention program to strengthen the internal resources of hospital nurses.

This study identifies the effects of HTML5 service quality on the use intention of smart learning and present the policy implications through empirical studies. This study select assurance, reliability, tangibles, responsiveness, empathy as independent variables of HTML5 service quality and also select perceived usefulness, degree of perceived ease of use as parameters and select use intention of smart learning as dependent variables. The control variables such as learning devices, service, learning place, use age, use times are adapted. As a result of analysis by applying the structural equation model, it was estimated that the reliability of HTML5 service quality, tangibles affect negatively on perceived ease of use, but reliability, assurance, tangibles, empathy, responsiveness of HTML5 service affect positive impacts on perceived usefulness, and also certainty, empathy, responsiveness was identified as positive impacts on the perceived ease of use. It was proven that perceived ease of use effect positive on the perceived usefulness and also usefulness or ease to use have positive effects on the usage intention of users.

The purpose of this study was to identify the mediating effects of positive thinking in the relationship between emotional expressivity and public speaking anxiety. Participants were recruited from one university freshmen located in Gwangju city. Data were collected from 146 university freshmen. The self-reported questionnaire was used to assess the level of positive thinking, emotional expressivity, public speaking anxiety. The SPSS WIN 23.0 version program was used with Baron and Kenny's 3-Step mediating effect and Sobel test. It was examined whether there was a mediating effect of positive thinking on emotional expression and presentation anxiety. In the second stage, emotional expressivity showed a significant effect on presentation anxiety. In stage 3, emotional expressivity was not statistically significant in presentation anxiety, and positive thinking was statistically significant in presentation anxiety. Positive thinking had a total mediating effect(z=-4.57, p<.001) in the relationship between emotional expressivity and public speaking anxiety. To reduce the public speaking anxiety among university freshmen, it is necessary to develop interventions that enhance positive thinking in addition to providing emotional expressivity.

The purpose of this study is to statistically analyze the correlation between block-coding software education and the resilience of elementary school students in order to research the significance of software education. In this study, 61 fourth grade students at an elementary school in Incheon were pre-tested for resilience. A block-coding education program from a nonprofit organization called code.org was used at the learner's level. 15 periods of classes and post-test were conducted to analyze the improvement of resilience. This study finds that control and positivity out of the three parts of resilience(control, positivity, sociality) of the students who took the block-coding classes improved statistically significantly as well as the overall score did too. This suggests that software education can foster not only students' computational thinking skills, but also their resilience, the power to live their lives positively and flexibly.

This study examined the effect of valence for best reply on the conformity of general reply in online environment. A total of 194 participants participated in this study, each participant assigned randomly in three experimental groups(positive, negative, and control). Participants were asked to read online news article, best reply and general 6 replies, and then, to write their own opinions in the reply section. In addition, the level of self-expression and issue commitment were measured. The contents of reply participants written was categorized three valence(positive, negative, and neutral) by the four experimenters' judgment. The mean of inter-rater reliability was 84.9%. The results indicated that the level of self-expression and issue commitment were comparable across experimental conditions. However, the result of cross-table analysis showed that there is a significant difference in the valence of general reply across experimental conditions. Specifically, there were significant difference in the valence of general reply between positive and negative experimental group and positive and control group, but there is no significant difference between negative and control group.
