The purposes of this study is to analyze gender difference in predictors of mobile phone dependency in youth. The analysis is performed with third-year panel survey data of middle school 1st grade students from Korean Child-Youth Panel Survey. The results are as follows. First, the female students' mobile phone dependency is more serious than the male students' mobile phone dependency. Second, while the identified male gender predictors are aggression, parental abuse, aprosexia, study activity and social withdrawal, the identified female gender predictors are depression, aprosexia, aggression, study activity and social withdrawal. Based on these results, theoretical and practical implications in planning of prevention or intervention of mobile phone dependency are proposed.

The purpose of this study is to explore the predictors of academic probation in college. Especially, this study focused on student engagement variables among the predictors of academic probation in college. Student engagement variables include hours of absence from class and numbers of log to LMS(Learning Management System) and in extracurricular program system during four weeks after the opening of a course and the numbers of faculty counseling. GPA(grade Point Average) is a dependent variable and GPA of prior semester is a control variable in this study. 17,261 student data were collected for the study. Linear regression model and logistic regression model analyses were conducted in the study. The finding showed that the hours of absence from class and numbers of log in extracurricular program system during four weeks after the opening of a course predicted academic achievement of college students. The result also indicated that hours of absence from class and numbers of log-ins to LMS(Learning Management System) and in extracurricular program system during four weeks after the opening of a course were the predictors of academic probation in college. This study will contribute to investigate indicators of students with low academic performance and to provide proper support for underachievers.

The purpose of this study was to investigate the influence of constructive factors of predictive variables related to suicidal ideation, in contrast to previous studies analyzing the influence of predictive variables related to suicidal ideation. The 11,755 subjects were participated in the 12th(2017) KoWePS. After the diagnosis of multicollinearity among constructive factors of predictive variables related to suicidal ideation, and are analyzed with the statistical program Spss 23.0 as a calling logistic regression. The major findings were as follows: The more patriarchal gender role increase, the more language violence occur, the more feel loneliness, the more people treat me cold, the more drinking' black-out occur, the odds ratio of suicidal ideation increases, while the more ladder score of life increase, the odds ratio of suicidal ideation decreases. Based on this result, we suggests social welfare implications to reduce or prevent suicidal ideation, and the limitations of this study and the suggestions for future studies were also presented.

This paper aimed to verify the current status of adolescents' donations and predictors influencing their donation behaviors. First, the result revealed that adolescents' donations were higher in the order of time, material, and talent donation. Second, donation motives, attitude towards donation, self-esteem, a sense of community, and trust in charitable organization were positively correlated. Third, the predictors of material donation behaviors of adolescents were gender, age, extrinsic motives, attitude towards donation, sense of community, and trust in charitable organization. And the predictors of time donation behaviors were gender and sense of community, and those of talent donation were age, intrinsic motives and sense of community. The strategies for the activation of adolescents' donations were suggested.

The purpose of this study was to investigate the effects of young children's empathic ability and interpersonal competence on caring behavior in forming relationships. Subjects included 152 4- and 5-year-old children attending a kindergarten located in a micropolitan city. Questionnaires required self-reporting by teachers, and were used to investigate young children's caring behavior, empathic ability and interpersonal competence in forming relationships. Data was analyzed using t-test, Pearson's correlation coefficient analysis and Stepwise-Regression analysis. Results were as follows: First, young children's caring behavior was negatively correlated with empathic ability and positively associated with interpersonal competence in forming relationships. Second, young children's emotional behavior as each domain of caring behavior were predictable variables for explaining the relative effect of the social reactivity and explaining the relative effect of relationship formation. Active behaviors were predictable variables for explaining the relative effect of follow-up instructions, but negatively affected mental burden. Normative behaviors were predictable variables for explaining the relative effect of social reactivity, but negatively predictable variables for explaining the relative effect of the relationship formation and mental burden. Value-contributing behavior in each domain of caring behavior were predictable variables for explaining the relative effect of the positive interaction.

The present study explored the impact of personality and self-identity on online information acquisition, information transmission and the usage of SNSs. Participants were 180 students, SNS users, from a university in Korea. Among the participants, 171 students completed all surveys. As a results, personality traits such as openness, extraversion, agreeableness, neuroticism were positively related to the SNS usage and information behaviors. Social identity orientation was associated with time spent of SNS and the number of friends whereas collective identity orientation was related to information acquisition. As a result of multiple regression, time spent, openness, agreeableness, collective identity were significant predictors of information acquisition. The number of SNS in use, time spent of SNS, openness, neuroticism were predictors of information transmission. However, as the predictor of information transmission, neuroticism showed inverse relationship with information transmission.

대형 할인점 매출 데이터는 G-CRM, 에어기어 마케팅(Area Marketing)에 활용하기 위해 고객의 구매정보와 위치정보를 포함한다. TM중부좌표로 이루어진 고객 위치정보를 이용하여 지점간의 거리를 구할 수 있다. 서로 다른 위치에서 통시에 측정된 자료들이 공간적인 변인에 의하여 영향을 받는다면, 공간적인 변인의 함수식에 의한 예측모형을 설정하는 것이 타당하다. 본 연구에서는 공간적인 변인으로 거리가 주어졌을 때, 대형 할인점 매출 자료에 대한 세미베리오그램(Semi-Variogram)의 모형을 추정하고, 관측되지 않은 지역에 대한 할인점 이용권을 공간예측기법으로 예측하였다. 그리고 공간예측 기법을 통해 예측된 할인점 이용권을 토대로 할인점 이용권 지도를 작성하였다. 또한 매출 데이터의 공간이상치 탐지를 위한 방법을 제시하고 실례로 알아보았다.

서로 다른 위치에서 동시에 관찰된 자료들이 공간적인 변인에 의하여 영향을 받는다면 공간적인 변인의 함수식에 의한 예측모형을 설정하는 것이 타당하다. 본 연구에서는 공간적인 변인으로 거리가 주어졌을 때, 공간자료에 대한 세미베리오그램 모형의 추정과 관측되지 않은 지점에 대한 공간예측기법을 정리하였으며, 또한 공간이상치 탐지를 위한 두가지 방법론으로 분포론적 방법과 p-Deletion 방법을 제시하였다. 방법론의 예시를 위하여 강우강도 자료를 이용하였으며 서로 상관되어 있는 공간데이터에 대한 시뮬레이션을 통하여 두가지 방법을 비교하였다.
