Conventional automotive development has mainly focused on ensuring correctness and safety and security has been relatively neglected. However, as the number of automotive hacking cases has increased due to the increased Internet connectivity of automobiles, international organizations such as the United Nations Economic Commission for Europe(UNECE) are preparing cybersecurity regulations to ensure security for automotive development. As with other IT products, automotive cybersecurity regulation also emphasize the concept of "Security by Design", which considers security from the beginning of development. In particular, since automotive development has a long lifecycle and complex supply chain, it is very difficult to change the architecture after development, and thus Security by Design is much more important than existing IT products. The problem, however, is that no specific methodology for Security by Design has been proposed on automotive development process. This paper, therefore, proposes a specific methodology for Security by Design on Automotive development. Through this methodology, automotive manufacturers can simultaneously consider aspects of functional safety, and security in automotive development process, and will also be able to respond to the upcoming certification of UNECE automotive cybersecurity regulations.

Objectives: The aim of this study was to establish the basic data for adolescents' mental health states in a community. Methods: 466 middle school and high school students were analyzed by visit-survey with an organized questionnaire from March to June 2008. K-YSR for measurement of mental health was used. Results: The score of total behavior (p<0.01), anxious/depressed (p<0.05), though problems (p<0.001), attention problems (p<0.001), aggressive behavior (p<0.01) and internalizing problems (p<0.05) in girls appeared significantly higher as compare to those the boys. Also, total competence (p<0.05) in high school students appeared significantly lower as compare to those middle school students. Withdrawn (p<0.01) in high school students appeared significantly higher as compare to those middle school students. The though problems (p<0.001) and aggressive behavior (p<0.05) in middle school students appeared significantly higher as compare to those high school students. The distribution of clinical group was school 93.8%, total competence 32.6%, attention problems 8.8%, total behavior problems 8.6%, anxious/depressed 7.7%, aggressive behavior 6.4% et. al. The social (p<0.05), anxious/depressed (p<0.05), attention problems (p<0.01), internalizing problems (p<0.05) and externalizing problems (p<0.05) in girls of clinical group were more frequent significantly as compared to those the boys of clinical group. Also, the social (p<0.01) in middle school students of clinical group was more frequent significantly as compared to those the high school students of clinical group. Conclusions: This study result will be significant in that it can provide basic data for the school mental health services.

This study was conducted in order to investigate the variables that relate and affect the internalizing and externalizing problems of multicultural children. 159 multicultural children in the $3^{rd}{\sim}6^{th}$grade were selected from elementary schools in Gwangju and the Jeollanamdo area. The data was analyzed by using the frequency, Cronbach's ${\alpha}$, t-test, ANOVA, Pearson's correlation and hierarchical regression by SPSS 12.0 program. The results were as follows: first, the internalizing problems were different according to the socio-demographic variable: (gender, subjective economic level), multicultural characteristic variable: (mother's communication ability, likability of mother's nationality, etc.), parent-child relationship variable: (relationship with mother, relationship with father) and social support variable: (peer support, teacher support). Further, the externalizing problems were different according to the socio-demographic variable: (gender), multicultural characteristic variable: (mother's nationality, mother's communication ability, etc.), parent-child relationship variable: (relationship with mother, relationship with father) and social support variable: (peer support, teacher support). Second, the influential variables regarding the internalizing problems were children's stress from cultural adaptability and the likability of the mother's nationality of the multicultural characteristic variable group, peer support of the social support variable group and the subjective economic-level of the socio-demographic variable group. Moreover, the influential variable on the externalizing problems was children's stress from the cultural adaptability of the multicultural characteristic variable group. The most influential variable of such variables was children's stress from cultural adaptability of the multicultural characteristic variable group. The results of this study will provide information for the development of educational and therapeutic intervention program for multicultural children.

본 논문은 지금까지의 다문화가정 아동들을 대상으로 한 선행연구들은 대부분 다문화가정 아동들의 사회적 심리적 요인들과 그들의 학교적응에 영향을 주는 요인들을 중심으로 연구들이 수행되어 왔다는 점에 대한 문제의식에 기초하였다. 따라서 다문화가정 아동들의 정서 행동문제에 대한 연구는 선행연구와는 달리 부모의 갈등과 양육태도, 정서 행동으로서의 내재화와 외현화 그리고 학교생활과 관련된 학교적응과 또래관계에 대해서 단편적이고 개별적인 변수들만의 관계만 고려하는 것이 아니라 종합적인 차원에서 변수들 간의 구조적인 관계에 대한 실증적인 연구의 필요성을 제시하였다.

The influence of depression, self-esteem, and well-being components of maternal psychological environment on child behavior problems was examined in Korean and American populations. Findings were that the level of mother's self-esteem was lower in Korean than in American mothers; the level of mother's "autonomy" and "environmental mastery" was lower in Korean than in American mothers; and "somatic complaints" were more frequent in the Korean group. The relationship between maternal psychological environment and child behavior problems was greater in the American group. In the Korean group, autonomy and enviornmental mastery were negative components causing both internalized and externalized behavor problems in children. Mothers' depression was the most powerful variable, affecting internalized and externalized behavior problems in both Korean and American groups.

Since the introductionof modern therapies, more children with cancer have survived their illness. As a result, an interest in the degree of adjustment achieved by cancer survivors has increased. In this study, quality of life and behavior problemsof child and adolescent cancer survivors were compared with those of healthy controls. Also, the patternsof the discrepancy between parent-report and self-report were compared. Childhood cancer survivors aged 8-18 and their mothers were participated in the study. Parent and self report versions of PedQL were administered to assess the quality of life. K-CBCL and K-YSR were further completed to assess internalizing and externalizing behavior problem. Results suggested that cancer survivors generally showed lower quality of life in physical and social domains and more internalizing behavior problem than healthy control group. However, the results were affected by the domain, age group, and informant. The pattern of discrepancy between parent and self report was similar. All parents reported higher levelsof quality of life and lower levels of behavior problems compared to the self reports of their siblings. In assessing internalizing problem behaviors, cancer survivor group showed greater discrepancy than the healthy control group.The implications, limitations, and directions for future research were also discussed.

This study examined the trajectories of the marital satisfaction of parents to classify its latent classes and how marital satisfaction influences the behavioral problems of their children between the identified latent classes. The 1st to 8th and 10th data from the Korea Child-Adolescent Panel Survey were analyzed using the latent class growth analysis and BCH method. First, based on the mother's trajectory of marital satisfaction, five latent classes were identified: 'low constant', 'intermediate constant', 'temporary increment-constantly decrement', 'high constant, and 'highest constant'. At the same time, based on the father's trajectory of marital satisfaction, four latent classes were identified: 'increment', 'intermediate-slightly decrement', 'high-slightly decrement', and 'highest constant'. Second, mothers with low marital satisfaction had more children with behavioral problems, and their influence had more problems with internalized behavioral problems. These problems progressed to externalized behavioral problems as they grew. Both internalized and externalized behavioral problems were also found between the identified latent classes of the father's marital satisfaction. Children of fathers with low marital satisfaction showed more behavioral problems. These findings suggest that the marital satisfaction of parents is an important variable that can influence the behavioral problems of their children.

The purpose of this study is to explore how students' fractional knowledge is related to their solving of proportion problems. To this end, 28 clinical interviews with four middle-grade students, each lasting about 30~50 minutes, were carried out from May 2021 to August 2021. The present study focuses on two 7th grade students who exhibited their ability to coordinate three levels of units prior to solving whole number problems. Although the students showed interiorization of three levels of units in solving whole number problems, how they coordinated three levels of units were different in solving proportion problems depending on whether the problems required reasoning with whole numbers or fractions. The students could coordinate three levels of units prior to solving the problems involving whole numbers, they coordinated three levels of units in activity for the problems involving fractions. In particular, the ways the two students employed partitioning operations and how they coordinated quantitative unit structures were different in solving proportion problems involving improper fractions. The study contributes to the field by adding empirical data corroborating the hypotheses that students' ability to transform one three levels of units structure into another one may not only be related to their interiorization of recursive partitioning operations, but it is an important foundation for their construction of splitting operations for composite units.

The purposes of this study were to show general trends in the degree of parental monitoring, self-control and problem behavior perceived by adolescents and to examine possible changes in such trends in accordance with gender of adolescents and mother's employment, and then to determine the effects of these variables on adolescents' problem behavior. The subjects were 1288 adolescents of middle school in Busan (male 661, female 627). The main results were as follow. (1) General trends in the degree of internalizing problems and total behavior problems showed that girls had more problem behaviors than boys. (2) Boys and girls with unemployed mother perceived more parental monitoring than ones with employed mothers. Boys with unemployed mother had more self-control than ones with employed mothers. Boys with employed mother showed more problem hehaviors than ones with unemployed mother. (3) Mother's employment, the degree of parental monitoring and self-control had a significant indirect effect on internalizing problems, externalizing problems and total behavior problems. (4) The degree of self-control was the most powerful predicator of problem behaviors of middle school students.
