The purpose of this study is to find how the childcare teacher aptitude of students majoring in childcare and education influences their perception of teacher professionalism. To achieve that, a questionnaire survey was conducted with 216 early childhood preservice teachers living in A city. For data processing and analysis, SPSS program was used so as to conduct frequency analysis and calculate the mean and standard deviation. In addition, to test reliability and find relations between variables, Cronbach's ${\alpha}$, correlation analysis, and multiple regression analysis were conducted. As a result, firstly, in terms of the childcare teacher aptitude perceived by the students majoring in childcare and education, they highly perceived an affinity with young children and a sense of calling of their job; in terms of their perception of teacher professionalism, they highly perceived social necessity and vocational ethics. Secondly, early childhood preservice teachers' childcare teacher aptitude had a statistically significant correlation with their perception of teacher professionalism. Thirdly, the sub factors of early childhood preservice teachers' childcare teacher aptitude all positively influenced the sub factors of the perception of teacher professionalism. Given the study results, the students majoring in childcare and education perceived the importance of their aptitude of childcare teacher. In order to provide high-quality childcare service and create the positive aptitude of childcare teacher, it will be necessary to conduct a variety of basic research.

We present a mixed multiplicative quantitative randomized response model which added a unrelated quantitative attribute and forced answer to the multiplicative model suggested by Bar-Lev et al. (2004). We also try to set up theoretical grounds for estimating sensitive quantitative attribute according to circumstances whether or not the information for unrelated quantitative attribute is known. We also extend it into the stratified mixed multiplicative quantitative randomized response model for stratified population along with two allocation methods, proportional and optimum allocation. We can see that the various quantitative randomized response models such as Eichhorn-Hayre's model (1983), Bar-Lev et al.'s model (2004), Gjestvang-Singh's model (2007) and Lee's model (2016a), are one of the special occasions of the suggested model. Finally, We compare the efficiency of our suggested model with Bar-Lev et al.'s (2004) and see that the bigger the value of $C_z$, the more the efficiency of the suggested model is obtained.

Using the 3rd to the 6th wave data from the Korean Children and Youth Panel Survey(KCYPS), we examined the effects of academic characteristics and social relations on the trajectories of the life satisfaction among adolescents. OLS results showed that male students were more satisfied with their lives than female students in the 3rd grade of middle school. As academic characteristics, academic achievement and the level of class adjustment improved life satisfaction but the amount of learning time spent had a negative effect on life satisfaction. However, the effect of academic achievement lost its statistical significance after including variables of social relations. Relationships with parents, teachers, and friends had positive effects on life satisfaction. The longitudinal analysis using the fixed effect estimation also showed a similar result of the associations among the variables to that in the OLS analysis. The life satisfaction gap between male and female students narrowed over time from the 3rd grade of middle school to the 2nd grade of high school. The effects of relationships with parents and friends showed significant effects on both female and male students, but the relationship with their teachers was significant only for female students. Based on the results, we discussed the issues of Korean education related to the life satisfaction among adolescents.

The purpose of this study was to examine the effects of emotion, home environment, school environment on self-regulated learning, focusing on motivational and behavioral regulation. Participants are 2070 students from 95 middle schools of Korean Children and Youth Panel Study(KCYPS). The variables of emotions, home environment, school environment and motivational regulation, behavioral regulation were analyzed using correlation analysis and multiple regression. The results were as follows. First, emotion, home environment, school environment were correlated with on motivational and behavioral regulation. Second, emotion explained motivational regulation and behavioral regulation of self-regulated learning as well as home envionment and school environment. All subvariables of emotion were significantly related to behavior control. Third, among subvariables of home environment, parents education and occupations, and annual household income were not significantly related to motivational regulation and behavioral regulation. However, home economic level perceived by students and parents' interest and abuse on students had great effects. Forth, school environment has a greater explanatory effect on motivational regulation and behavioral regulation. Particularly, friendships and relationships with teachers during learning activities had a significant effect. These results showed that emotion and psychological environment of learning environment are important variables affecting on self-regulated learning and suggests the need for researches on these variables.

Objectives: The number of schools offering school lunches has increased in China. This study examined the dietary quality of the lunches consumed by Chinese school-age children and adolescents, with a focus on comparing school lunches with home lunches. Methods: The first weekday 24-hour dietary recall data of 6~17-year-old students (n=1,084) from the 2011 China Health and Nutrition Survey were analyzed. The subjects were divided into the school lunch group and the home lunch group, and the dietary quality of lunches was compared between the two groups among 6~11-year-old students (n=634; 177 in the school lunch group and 457 in the home lunch group) and 12~17-year-old students (n=450; 144 in the school lunch group and 306 in the home lunch group), respectively. Frequently consumed foods, amount of food group intake, food group intake pattern, Dietary Diversity Score (DDS), and Dietary Variety Score (DVS) were examined. Results: The most frequently consumed foods in both lunch groups were rice and pork. An excessive intake of meat and insufficient intake of seafood were noted in both lunch groups. The school lunch group showed a lower level of vegetable consumption than the home lunch group (P=0.017 in 6~11-year-old students, P=0.003 in 12~17-year-old students). Although more students ate meals with a better dietary pattern in the school lunch group than the home lunch group, there were no significant differences in DDS and DVS between the two groups. Conclusions: Overall, the dietary quality of lunches was not superior in the school lunch group compared to the home lunch group. This suggests that much room remain for improving dietary quality of school lunches in China.

This study analyzed 28 domestic and foreign studies related Prompts for Restructuring Oral Muscular Phonetic Targets treatment techniques from 1984 to 2020 to prepare basic data for the development of PROMPT intervention programs and examination tools. According to the analysis, continuous research has been conducted since 1984 when the prompt study was first started, and the method of research was 16 intervention studies, with the highest number of speech disorders, and the target age being 3 to 5 years old, the most frequently conducted for infancy. The treatment was the most frequent in the 16th sessions, and the activities were based on the Motor Speech Hierarchy(MSH), except for the subjects of the non-verbal autism spectrum disorder. According to the analysis of the dependent variables, 'speech production' was the most common, followed by 'speech motor control', 'articulation', and 'speech intelligibility' were highest. Combined with all these studies, it suggests that PROMPT, which are directly useful for exercise spoken word production, are effectively being used outside the country and that it is necessary to develop a PROMPT program that can be applied domestically, in Korea.

This study aimed to identify the effects of adolescents' self-perceived health on their life satisfaction and verify the mediating effects of the relationship between the two factors. The analysis was conducted using the Korean Children and Youth Panel Study (KCYPS, Ed. 6), and the results are as follows. In terms of the factors, the mean value of the adolescents' self-perceived health was 3.13, which was regarded as a moderate level, while the values of life satisfaction and self-esteem were 2.80 and 2.90, respectively, which were regarded as low levels. An analysis of the study model showed that the adolescents' self-perceived health affected their life satisfaction, and self-esteem played a meditating role in such a relationship. In other words, a higher level of self-perceived health would help improve self-esteem, which would promote a level of life-satisfaction. Therefore, this study has implications that healthcare or psychological/ emotional resources have been identified to influence adolescents' life satisfaction. Furthermore, multidimensional interventions are needed to reinforce the individuals' psychological and develop emotional resources in healthcare or welfare fields. Moreover, efforts are needed to enhance the adolescents' self-perceived health that would affect their life satisfaction.

The purpose of this study was to explore types of longitudinal changes in interactions between mothers and 4-year-old children in primary school as well as the effects on media device addiction. To explore interaction types between mothers and children, latent class growth modeling (LCGM) and BCH were used in a three-step approach. Data from the 6-10th wave of the Panel Study of Korea Children were used. First, the trajectory of the mother-child interactions was linear and decreased across time. This linear decrease was classified into the following three trajectories: high-decreasing, average-deceasing, and low-decreasing. Second, BCH was performed to examine media device addiction in each trajectory, and the findings show that children who had low initial mother-child interactions over time were more likely to experience daily disturbances in adaptive functions such as withdraw or tolerance than other groups of children. The results indicate that maximizing the quality of mother-child interactions in childhood through primary school can lower media device addiction in children.

This study aims to identify the effects of factors on aggression in adolescents, focusing on the individual, parent, friend factors and SNS usage. In particular, this study is to provide a basis for easing aggression in adolescence by considering the emotional relationship of parents and friends. This study analyzed frequency, t-test, one-way batch distribution analysis(ANOVA), and multi-linear regression, using the data from the 7th year of the Korean Children and Youth Panel Survey. As a result, adolescents who frequently use SNS are more aggressive than adolescents who use less. Among the parental factors, the more abuse and excessive interference were found to be more aggressive, and the higher the coach, the lower the aggressiveness. Furthermore, among the friend factors, it has been shown that the higher the alienation, the more aggressive adolescents are. In order to reduce aggression among adolescents, it is necessary to prepare an integrated program considering the emotional relationship of parents and friends, who are the most influential neighbors, rather than simply restricting the use of SNS.
