This study analyzed the factors influencing the satisfaction of school students in Covid-19. The subjects of the study were surveyed in all 5th-6th grade of elementary school students, 1st-3rd grade of middle school, and 1st and 2nd grade of high school students in G metropolitan city. A total of 13,672 students participated in the survey, of which 13,613 were used for final data analysis. A hierarchical regression analysis of factors affecting students' life satisfaction showed that 22.2% of school life factors, 4.7% of home life factors, and 10.7% of daily stressors. The most influential factor in Covid-19 was home life satisfaction. Next was appearance stress for elementary school students and academic stress for middle and high school students. This can be seen as a result of Covid-19, which increased non-face-to-face classes and increased time for students to spend at home, which led to a greater impact on students' satisfaction in life. Nevertheless, middle and high school students can still see that academic stress has a significant impact on life satisfaction. Through this, it is necessary to support students to facilitate relationships, communication, studies, and leisure at home in the context of Corona 19. Especially, various educational policies must be accompanied so that the educational gap due to non-face-to-face classes does not deepen depending on the family environment.

The purpose of this study is to analyze the 'Action Competence on Climate Change(ACoCC)' shown in 12 types of middle school 「Technology & Home Economics」 textbooks written according to the 2015 revised curriculum, and to suggest ways to improve the activity tasks. According to the results of the analysis, first, the 'knowledge on climate change' was the most frequently mentioned, and 'climate change communication' was the least frequently mentioned in the textbook among ACoCC. Second, all 12 textbooks dealt with 'knowledge about climate change' most frequently, yet the frequency of mentioning other competencies differed by publisher. In relation to the core concepts, the ACoCCs were most often discussed in the 'Management,' yet never discussed in the 'Life Design' at all. In relation to the academic sub-fields of home economics, the 'clothing life' showed the highest frequency of mentioning ACoCCs, while 'family life' the lowest frequency. Based on the results of the above analysis, it was suggested that the capacity to respond to climate change should be dealt with in the overall fields of home economics education. This study has implications as a basic study related to climate change in home economics education, and it is expected that various research and educational programs in home economics education that focus on climate change mitigation are implemented in the future.

This study focuses on the increasing supply and consumption of affair dramas on TV with the theme of unconventional 'infidelity', therefore, is an empirical study that reveals factors related to the problem consciousness of married men and women about infidelity dramas that can affect the sexual socialization of married men and women. This study investigates the effect of married men and women's right to sexual self-determination between couples, personal psychological characteristics (emotional maturity, emotional alienation, self-perception), surrounding environmental characteristics (prevalence of extramarital relationships), and demographic background (gender, age, educational background, economic level) on 'the presence or absence of critical consciousness of infidelity dramas'. For the data of this study, an online survey is conducted on married men and women(614 people), and binary logistic analysis is conducted using SPSS. As a result of this analysis, first, 46% of married men and women have a relatively good level of critical awareness of affair dramas, and overall, the level of critical thinking of married men and women about the infidelity dramas is rather low. Second, there is no significant difference between genders in the perception of problems such as 'excessive beautification of infidelity', 'incitement of infidelity' and 'damage of family values', however, married women are more critical than married men regarding 'explicit sexual description', indicating differences according to gender characteristics. Third, for married men, the level of 'self-perception' and 'marital sexual self-determination right' have a significant effect on the critical mind with infidelity dramas. In the case of married women, it is found that 'the right to sexual self-determination' between married couples and 'emotional alienation' have a significant effect on 'the presence or absence of critical consciousness of infidelity dramas'.

The purpose of this study is to classify the potential types of mental health of mothers of multicultural youth by applying Latent Profile Analysis, analyze the influence of predictors, and find out how differences in potential types affect parental efficacy. To this end, panel data for the 9th year (2019) of the Multicultural Youth Panel Survey (MAPS) were used. As a result of the analysis, first, the mental health types of mothers of multicultural adolescents were analyzed in the order of 'middle risk type of mental health'(class3) > 'high risk type of self-esteem'(class1) > 'high risk type of mental health'(class4) > 'cultural adaptation and daily life stress'(class2). Second, compared to the "class 1" group, the lower the family economy level of multicultural youth mothers, the lower the educational background of multicultural youth fathers (husbands) graduate from middle school, the lower the level of Korean, and the lower the level of communication with children, the higher the odds of belonging to the 'mental health medium risk' group (Ods). Third, compared to the 'middle risk type of mental health'(class3) and 'high risk type of mental health'(class4), the 'high risk type of self-esteem'(class1) group was found to have a significant positive (+) effect on parental efficacy.

As high-performance quantum computers are expected to be developed, studies are being actively conducted to build a post-quantum security system that is safe from potential quantum computer attacks. When the Grover's algorithm, a representative quantum algorithm, is used to search for a secret key in a symmetric key cryptography, there may be a safety problem in that the security strength of the cipher is reduced to the square root. NIST presents the post-quantum security strength estimated based on the cost of the Grover's algorithm required for an attack of the cryptographic algorithm as a post-quantum security requirement for symmetric key cryptography. The estimated cost of Grover's algorithm for the attack of symmetric key cryptography is determined by the quantum circuit complexity of the corresponding encryption algorithm. In this paper, the quantum circuit of the SCHWAEMM algorithm, AEAD family of SPARKLE, which was a finalist in NIST's lightweight cryptography competition, is efficiently implemented, and the quantum cost to apply the Grover's algorithm is analyzed. At this time, the cost according to the CDKM ripple-carry adder and the unbounded Fan-Out adder is compared together. Finally, we evaluate the post-quantum security strength of the lightweight cryptography SPARKLE SCHWAEMM algorithm based on the analyzed cost and NIST's post-quantum security requirements. A quantum programming tool, ProjectQ, is used to implement the quantum circuit and analyze its cost.

The purpose of this study was to identify the latent profiles according to the core competencies of middle school students and to examine whether the parent-child relationship predicts the latent profiles based on the core competencies for students defined by the Korean Ministry of Education. To achieve the purpose of the study, a total of 6,065 second-year middle school students were analyzed from the fourth year of the Korean Educational Longitudinal Study (KELS 2013), which was conducted by the Korean Educational Development Institute in 2016. The results of latent profile analysis and multinomial logistic regression are as follows. First, three latent profiles (higher competency group (19.54%), middle competency group (49.03%), and lower competency group (31.43%)) were derived according to the core competencies. For all groups, the highest competency was communication ability, and the lowest was creative ability. Second, the variables of the parent-child relationship (i.e., parental academic support, emotional support, and attachment level) were significant in predicting differences among the core competency latent profiles. In particular, the emotional support of parents was found to have the greatest influence on the core competencies of middle school students. This study identified the influence of the parent-child relationship on the development of core competencies. Further, it showed that a good family relationship is important for the holistic development of adolescents.

Block cipher is not expected to be safe for quantum computer, as Grover's algorithm reduces the security strength by accelerating brute-force attacks on symmetric key ciphers. So it is necessary to check the post-quantum security strength by implementing quantum circuit for the target cipher. In this paper, we propose the optimal quantum circuit implementation result designed as a technique to minimize the use of quantum resources (qubits, quantum gates) for SIMECK lightweight cryptography, and explain the operation of each quantum circuit. The implemented SIMECK quantum circuit is used to check the estimation result of quantum resources and calculate the Grover attack cost. Finally, the post-quantum strength of SIMECK lightweight cryptography is evaluated. As a result of post-quantum security strength evaluation, all SIMECK family cipher failed to reach NIST security strength. Therefore, it is expected that the safety of SIMECK cipher is unclear when large-scale quantum computers appear. About this, it is judged that it would be appropriate to increase the block size, the number of rounds, and the key length to increase the security strength.

The health care services are the most basic social institutions that are provided to citizen including disabled persons for improvement of health. However, the study of the difference of health care services according to the speech therapy use in the people with speech-language disorders was insufficient. The aim of this investigation was to compare the awareness of health care services and characteristics of people with speech-language disorders according to speech therapy use. The researchers selected 229 people with language disorder using raw data of National Survey of the Disabled Person (2017). We compared the characteristics and health care services of people with speech-language disorders by distinguishing between speech therapy non-users and speech therapy users. Among the 229 people with language disorder, speech therapy users were 37 persons (16.2%). In comparison with non-users, users were younger, more preschoolers, more family incomes, and intellectual disabilities and autistic disorder were the most common types of disability enrollment. Users had a lower proportion of unmet medical needs than non-users. For the reasons of unmet medical need, there were 6.8% and 6.3% of the "economic reasons" and "communication difficulties" Both users and non-users responded that "disability management services" need to be strengthened by the government. In conclusion, we suggest that access to health care services needs to be increased to lower the barriers of speech therapy use.

The purpose of this study is to explore implications for intergenerational Christian education in Korean churches and families that struggle with "generational fragmentations" focusing on the conception of reciprocity and participation. For the faith community in Korea, "generational fragmentations" does not merely mean communication gaps or the disconnection between generations but also the absence of reciprocity and communal participation as a genuine intergenerational community of faith. With this phenomenon in mind, this study explores the concept of "intergenerationality" in education, focusing on reciprocity and participation. Next, this study examines the concepts of reciprocity and participation found in John Dewey's seminal works, Democracy and Education and Experience and Education based on his ideas of democracy and experience in relation to intergenerational Christian education for the Korean church and families. The present paper then attempts to find implications for intergenerational Christian education in the Korean church and family, showing the importance of an intergenerational community of faith with reciprocity and communal participation, and communal spiritual journey with children and adults.

Objective : Autistic Spectrum Disorders(ASD) is a developmental disorder characterized by atypical sensory adaptation, communication problem, stereotyped behavior, and feeding disorders. The reasons for ASD feeding disorders are oral sensory motor, cognitive, behavioral, and social problems. Major symptoms include picky eating, selective eating, food refusal, food neophobia, limited food variety, and food aversion. ASD feeding disorders could be accompanied by various problems such as health and nutrition intake problems, feeding development, eating-related sociability, and family and caregiver stress. Feeding problems and disorders in ASD can present from birth. However, ASD is diagnosed by the age of 3, and there might be an appropriate treatment gap. Usually, symptoms of feeding disorders tend to decrease with age. However, the symptoms often remain, so early evaluation, intervention, and periodic checking are necessary. In this study, the general information about the feeding disorder characteristics of ASD, influencing factors, and intervention were described through a literature review. Conclusion : Sensory-based therapy and behavior-based therapies are generally used for feeding disorders in ASD. Sensory-based therapy is effective for food sensitivity and behavior-based therapy for food selection. As the symptoms of feeding disorders in ASD are diverse, a comprehensive approach includes play and participation, oral motor exercise, diet, and daily life. However, appropriate evaluation, intervention protocol, and guidelines for the treatment of feeding disorders in ASD are limited. Therefore, a complex approach based on a more systematic understanding is needed. Feeding rehabilitation specialists, such as occupational therapists, should provide appropriate evaluation and intervention.
