Cloud Computing has recently begun to emerge as a new attack target. The malice DDoS attacks are ongoing to delay and disturb the various services of the Cloud Computing. In this paper, we propose the Hornet-Cloud using security Honeypot technique and resources of Cloud Computing, define and design the concept of security functions about active low-interaction framework by cyber resilience simply. In addition, for virtual honeypot service, we simulated and vitrified the possibility of functions of the low-interaction vHoneypot using cyber resilience.

The purpose of this study is to understand the impact of emotional labor of disabled infant teachers on job stress and to understand the mediated effect of resilience in these relationships. The subject of the study is a disabled infant teacher at a daycare center specialized in disabled children. The survey was conducted on a self-contained basis, and a total of 203 copies were recovered and 194 were analyzed except for 9 unfaithful responses. First, the higher the level of emotional labor, the higher the job stress. Second, the higher the level of emotional labor, the lower the resilience. Third, resilience had a partial mediated effect in the impact of emotional labor on job stress. Therefore, measures are needed to prevent job stress and improve resilience for disabled infant teachers.

Cyber attacks targeting critical infrastructure are on the rise. Critical infrastructure is defined as core infrastructures within a country with a high degree of interdependence between the different structures; therefore, it is difficult to sufficiently protect it using outdated cybersecurity techniques. In particular, the distinction between the physical and logical risks of critical infrastructure is becoming ambiguous; therefore, risk management from a comprehensive perspective must be implemented. Accordingly, as a means of further actively protecting critical infrastructure, major countries have begun to apply their security and cybersecurity systems by design, as a more expanded concept is now being considered. This proactive security approach (CSbD, Cybersecurity by Design) includes not only securing the stability of software (SW) safety design and management, but also physical politics and device (HW) safety, precautionary and blocking measures, and overall resilience. It involves a comprehensive security system. Therefore, this study compares and analyzes security by design measures towards critical infrastructure that are leading the way in the US, Europe, and Singapore. It reflects the results of an analysis of optimal cybersecurity solutions for critical infrastructure. I would like to present a plan for applying by Design.

Korean society has experienced so-called 'societal crisis' in many aspects of society for a couple of decades and those crises include both natural disasters and tragic catastrophes. Given that, this study purports to investigate, first of all, what is the definition of crisis in general and societal crisis in specific. Next question is what are the major types of societal crises and what are the indicators for those crises. As a result, many areas of societal crisis and corresponding indicators in each area will be introduced. Finally, this study tries to establish a new definition of societal crises based upon a more sociological, more specifically a more phenomenological point of view. For these research purpose, in-depth review for previous research on the subject will be done including psychological and sociological materials. Final outcome of this study will be a new and experimental definition of societal crisis, which will provide the principle base for actual numeric indicators of societal crisis in both macro and micro level.

Objective: The purpose of this study was to examine the effects of maternal parenting stress and mother's ego-resilience on mother-child attachment. More specially, mother-child attachment for higher grade elementary school children was examined according to the internal working model. Methods: Participants were 190 mothers of fourth and fifth grade elementary school children. The Maternal Parenting Stress Scale(Shin, 1997), the Scales of Ego-resilience(Yoo & Shim, 2002), and Inventory of Parent Attachment(Yang, 2006) were used to measure variables. Collected data were analyzed by descriptive statistics, t-test, correlation analysis and multiple regression analysis. Results: The major findings were summarized as follows: First, there were no differences between mother-child attachment according to children's gender. Second, mother-child attachment was negatively correlated with maternal parenting stress and positively correlated with ego-resilience. Next, maternal parenting stress_interaction and ego-resilience explained mother-child attachment_trust. Last, maternal stress_interaction explained mother-child attachment_isolation. Conclusion/Implications: In conclusion, the study results showed that maternal parenting stress and ego-resilience influenced mother-child attachment. based on the results, the implications of this study were discussed.

This study tried to identify the psychological mechanisms that middle and high school students can adaptively solve various problems, and to identify differences according to gender and school level. To this end, the growth mindset was set as an independent variable predicting the problem-solving ability of middle and high school students, and ego-resilience and emotional intelligence were set as the mediating variables. As for the research data, responses of 94 middle school students(40 males, 54 females) and 134 high school students(63 males, 71 females) who participated through mobile and off-line were analyzed using SPSS 24.0 and AMOS 18.0. The results are as follows. First, differences according to gender and school level were significant only in emotional intelligence. Second, ego-resilience and emotional intelligence mediated the relationship between growth mindset and problem-solving ability respectively. Third, the dual mediation effect of ego-resilience and emotional intelligence was significant in the relationship between growth mindset and problem-solving ability. Based on these results, theoretical and practical discussions and implications for improving problem-solving ability of middle and high school students are presented.

The purpose of this study was to increase the power of color and examine the long-lasting power, which is a disadvantage of one-pack acid hair dye by using chestnut shell pigment. For this, hair dyeing power was measured using a spectrophotometer, the optical density(O.D.) value was measured to examine the degree of fading of the hair, and the elasticity of the hair was analyzed by measuring the tensile strength. As a result of comparing the results of applying different leaving times and treatment methods to the hair samples of each level, the experimental group that was heat-treated for 20 minutes showed the highest dyeing power. Then, it was confirmed in the order of 40 minutes of natural exposure, 10 minutes of heat treatment, and 20 minutes of natural exposure. And it was also confirmed that the color expression visually improved as it went up to level 10. However, at level 10, it was confirmed that some water loss occurred even after 3 days and the tensile strength was low. These findings that indicated the beauty industry will popularize a one-step acid hair dye containing various natural dye ingredients to help maintain modern people's well-being and healthy mind and body.

In this study, the quality characteristics and antioxidant activities of wet noodles added with seunggumcho (Angelica gigas N Leaf) powder at concentrations of 1, 2, 3, and 4%, respectively, were investigated. The moisture contents and pH of the samples showed a tendency to decrease with increasing amounts of seunggumcho powder. Texture measurement indicated that 'hardness,' 'springiness,' and 'chewiness' of the cooked noodle were the highest in the control group, and these parameters showed a tendency to decrease with increasing amounts of seunggumcho powder. The total polyphenol contents in wet noodles added with seunggumcho powder increased with increasing amounts of seunggumcho powder. 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity was the lowest in the control group (10.85%) and highest in the 4% addition group (44.84%). ${\alpha}-Glucosidase$ inhibitory activity showed the lowest value in control group (1.17%), and increased with increasing amounts of seunggumcho powder. The sensory preference score was the highest for color, flavor, taste, and chewiness in the 2% addition sample. The findings of this study suggest the feasibility of seunggumcho added wet noodles as a health food with physiological benefits and provide evidence for introducing various health foods by adding seunggumcho.
