The purpose of this study was to investigate adolescents' individual and microsystem variables including relationships with parents and friends affecting adolescents' experiences of mobile social networking site (SNS) cyberbullying based on the human ecological perspective. Data came from 344 middle school students who lived with both their parents in the Seoul and Gyunggi areas. A multiple regression analysis showed that adolescents' characteristics, relationships with parents, and friends were associated with their experiences of mobile SNS cyberbullying. These findings suggest that good relationships with parents could be protective factors for adolescents to reduce mobile SNS cyberbullying. However, adolescents' characteristics including aggression, depression, and delinquent peers were positively associated with adolescents' experiences of mobile SNS cyberbullying. This study highlights that various environments are closely related to adolescent development.

Information about the characteristics of street-living versus shelter-residing youth is vital for tailoring prevention and intervention efforts to the unique needs of runaway and homeless youth. The present study compared two samples of youth [street-living (n=73) versus shelter-residing (n=205)], between the ages of 14 to 17 years, on behavioral and emotional factors and service use. Based on the different characteristics of the two groups, the predictors explaining the living status of the runaways and homeless youth were explored. In general, street-living youth reported more severe substance use, depressive symptoms, and risky sexual behavior, but less lifetime service involvement compared to shelter-residing youth. The factors that predicted shelter-residing status were related to younger age, prior service care experience, more knowledge about HIV, and engaging in less delinquent and risky behavior. Given the little overlap among youth in service involvement and the greater severity faced by street-living youth, the conclusions highlight the need for increased funding and attention towards facilitating the ability of street-living youth to find and enter mental health and reintegration services.

The present study investigated the effects of individual, family, school, and community factors on the onset of adolescent runaway behavior. Using the Korean Youth Panel data(n=3,118), discrete-time survival analysis was applied for research purposes. Results showed that the likelihood of onset of adolescent runaway behavior increased sharply during the early middle school years. The variables of self-control, aggression, parents' divorce, paternal abuse, attachment with parents, and number of delinquent peers were associated with the likelihood of runaway behavior. These results suggest that special attention should be paid to adolescents in the early middle school years and that various preventive programs, e.g., aggression and stress management, and peer relations programs, should be developed and implemented.

This study aimed at developing a Social Readjustment Group Therapy Program for delinquents under probation. This program intended to enhance the participants'self-esteem, impose control, daily life habits and relationship with parent. Thirty one male delinquents were chosen from a Probation Center in Seoul, and were divided into one of the four small groups. Group Therapy based on Solution-Focused Brief Therapy Model was given for three hours for ten sessions by four group leaders and four assistants. Results showed meaningful improvement over all of the above target behaviors, especially self-esteem.

The purpose of this study was to validate the Child Behavior Checklist(CBCL) with a population of Korean children. Subjects were 415 mothers of fourth and sixth graders selected from five elementary schools in Seoul. The CBCL(Achenbach, 1991) and the Child Behavior Questionnaire(CBQ; Rutter et als., 1970) were used as a methodological instrument. Statistics used for data analysis were ${\chi}^2$, Cramer's V, factor analysis, Pearson's r, and Cronbach's ${\alpha}$. The major findings were that 102 items of the 107-item scale were found acceptable through the item discriminant method. Nine factors (anxious behavior, hyperactive behavior, immature behavior, delinquent behavior, aggressive behavior, withdrawn behavior, thought problems, somatic complaints, other problems) were extracted by factor analysis. The correlation between the CBCL and the CBQ was examined to test criterion-related validity, and the coefficient was significant (r=.78, p<.001). Finally, the internal consistency of the CBCL appeared to be at an acceptable level (Cronbach's ${\alpha}$=.83).

본 연구에서는 본 연구의 목적은 청소년 일탈행위가 학업성취도에 어떠한 영향을 미치는지를 살펴보고 청소년문제의 기초자료 활용과 시사점의 제공에 목적을 두고자 하였다. 이를 위해 통계자료를 활용하여 요인분석은 Varimax에 의한 직교회전에 의하여 요인적재치를 산출하였고, 설문문항에 대한 측정은 크론바하 알파계수(Crobach's Alpha)를 이용하여 신뢰도 검증을 실시하였다. 연구결과 먼저, 학업생활의 전념이 성에 따라 일탈행위에 유의미한 영향을 미치지 않은 것으로 나타났다. 둘째, 비행친구와의 접촉이 성에 따라 일탈행위에 유의미한 영향을 미치는 것으로 나타났다. 셋째, 학업성취도가 성에 다라 일탈행위에 유의미한 영향을 미치는 것으로 나타났다.

This paper reviewed the researches of adolescent's behavior as following three main viewpoint in order to defend the impairment of adolescent's rights to their own life style: (1) the influences of environmental factors(family, school and society) to adolescent's behavior, (2) the influences of adolescent's activity areas or activities to their behavior and (3) the understanding of adolescent's behavior by the analysis of their delinquent activities. For further understandings of adolescent's behavior, the dynamic research approaches and the interdisciplinary studies are necessary.

This study introduces an effective method for predicting individual local tax delinquencies using prevalent machine learning and deep learning algorithms. The evaluation of credit risk holds great significance in the financial realm, impacting both companies and individuals. While credit risk prediction has been explored using statistical and machine learning techniques, their application to tax arrears prediction remains underexplored. We forecast individual local tax defaults in Republic of Korea using machine and deep learning algorithms, including convolutional neural networks (CNN), long short-term memory (LSTM), and sequence-to-sequence (seq2seq). Our model incorporates diverse credit and public information like loan history, delinquency records, credit card usage, and public taxation data, offering richer insights than prior studies. The results highlight the superior predictive accuracy of the CNN model. Anticipating local tax arrears more effectively could lead to efficient allocation of administrative resources. By leveraging advanced machine learning, this research offers a promising avenue for refining tax collection strategies and resource management.

Objectives：This study investigated the characteristics of detained delinquent adolescents and variables related to the repeated crime during 6 months after release. Methods：The socio-demographic and crime-related characteristics of 73 detained adolescents were evaluated by semi-structured interviews and police records, and the psychological characteristics of them measured by the MMPI. We also compared the characteristics between subjects with and without repeated crime during 6 months after release. Results：1) Most of detained adolescents had families with low socioeconomic status(77%) and broken families(48%). Sixty-six percent of them were dropped out of school. The most frequent crime pattern was theft(49%), and with accomplice(77%). Seventy-five percent of total subjects had the records of previous conviction. Of the previous convictions, seventy-eight percent was same with the present crimes. 2) Subjects with repeated crime during 6 months after release were younger and had higher T-score on Pa scale of MMPI than the subjects without repeated crime. More adolescents with repeated crime had broken families than those without repeated crime. They also showed the crime-related characteristics of higher percent of theft among crime patterns, higher incidence of previous conviction, younger age of the first crime, and shorter crime-free duration from the last to present crime. Conclusion：These results of present study suggest that the development and the persistence of adolescent delinquency would be resulted from interaction of factors of individual, family, school, and community. By the comparison between subjects with and without repeated crime, it was found that familial dysfunction, younger age at first crime, presence of previous conviction might be the risk factors for repeated delinquency. To prevent repeated crime of delinquent adolescents more effectively, early therapeutic intervention and the development of programs to help adaptation in school and community would be essential.
