This study examined the effects of marital relationships, mother's parenting stress and positive parenting behavior on the behavioral problems of preschoolers. For this purpose, we created a structural equation model and examined the goodness of fit of the model using the RMSEA, SRMR, TLI, and CFI. The participants were 986 4-year-old preschoolers and their mothers taken from the 5th year of the Korea Children's Panel. The results of this study were as follows: First, a negative marital relationship had a significant negative effect on behavioral problems of preschoolers directly. And a negative marital relationship had a significant indirect effect on behavioral problems of preschoolers through the parenting behavior. Second, parenting stress had a significant negative effect on behavioral problems of preschoolers directly. And parenting stress had a significant indirect effect on behavioral problems of preschoolers through the parenting behavior. These findings imply that both improving marital relationships and regulating mothers' parenting stress and parenting behavior need to be emphasized when designing prevention and intervention programs aimed at improving the behavioral problems of preschoolers.

The purpose of this study was to examine children's emotional and behavioral problems using parent and teacher ratings. The study also explored how children's individual factors were associated with their problems. The Strengths and Difficulties Questionnaire Korean version (SDQ-Kr) was completed by parents and teachers of 157 elementary school students. Parents reported perceptions of their child's social skills. Children completed the measure of self-esteem. The results showed that moderate to strong correlations were found between parents and teachers, revealing a stronger correlation in regard to hyperactivity than to emotional problems. Self-esteem and social skill were associated with emotional and behavioral problems in children classified by socio-emotional developmental level. Integrating information from parents and teachers can provide a more complete portrait of a child's adjustment and can better identify a child's problems. These findings highlight that self-esteem and social skill may play critical roles in intervening on children's emotional and behavioral problems.

The purpose of this study is to investigate various kinds of discipline problems in middle school classrooms, and the differences in severity and frequency of the classroom discipline problems between male and female students' classrooms in middle schools. This study shows that the discipline problems in the middle school classrooms include using a cellular phone, chattering, sleeping, chewing gum, reading comic books, asking useless questions, challenging a teacher, fighting, calling names, skipping class, throwing trash in the classroom, breaking classroom equipment, creating disorder, losing materials, playing with a ball in the classroom, gambling, and so on. Generally, male students recognized the severity of the classroom discipline problems more than the female students. However, it is shown that the frequency of discipline problems in male students' classrooms is higher than that in female students' classrooms. From the results of this study, male students have more active discipline problems (playing with a ball in the classroom, throwing trash in the classroom, coming to class late, gambling, cutting in line, and so on). On the other hand, female students have more passive discipline problems (making a noise by using a cellular phone, asking useless questions, sending messages to a classmate, studying other subjects, scattering, and so on).

Several estimation methods used in the range measurement based wireless localization area have individual problems. These problems may not occur according to certain application areas. However, these problems may give rise to serious problems in particular applications. In this paper, three methods, ILS (Iterative Least Squares), DS (Direct Solution), and DSRM (Difference of Squared Range Measurements) methods are considered. Problems that can occur in these methods are defined and a simple hybrid solution is presented to solve them. The ILS method is the most frequently used method in wireless localization and has local minimum problems and a large computational burden compared with closed-form solutions. The DS method requires less processing time than the ILS method. However, a solution for this method may include a complex number caused by the relations between the location of reference nodes and range measurement errors. In the near-field region of the complex solution, large estimation errors occur. In the DSRM method, large measurement errors occur when the mobile node is far from the reference nodes due to the combination of range measurement error and range data. This creates the problem of large localization errors. In this paper, these problems are defined and a hybrid localization method is presented to avoid them by integrating the DS and DSRM methods. The defined problems are confirmed and the performance of the presented method is verified by a Monte-Carlo simulation.

Objective: This study aimed to examine the longitudinal relations of children's temperamental attributes (i.e., emotionality, activity, and sociability) and maternal responsiveness to overall and specific externalizing/internalizing behavior problems during the preschool period. Methods: Data (N=1,438) from the 4th and 6th wave of Panel Study on Korean Children (PSKC) were used in a series of hierarchical regression analyses. The analyses were conducted to determine the additive and interactive effects of maternal responsiveness and temperamental attributes of children at the age of 3 years on the broadband and narrowband scales of their behavior problems at the age of 5 years. Results: Overall, results confirmed the additive and interactive effects of maternal responsiveness and temperamental attributes on the levels of different domains of behavior problems. Examination of the interactive effects showed that maternal responsiveness was more strongly related to some behavior problems for temperamentally vulnerable children as compared to children with less temperamental vulnerabilities. Conclusion: The findings suggested that the beneficial effects of positive parenting on the development of behavior problems might be more pronounced for temperamentally vulnerable than for less vulnerable children.

This study examined the causal relationship between a mothers' depression and the emotional problems of their preschool-aged children as indicated by anxiety, depression and emotional reactivity. We analyzed data from 1,528 mothers and their children from the Panel Study of Korean Children (PSKC) collected when the children were 4 years old and 5 years old. Autoregressive cross-lagged modeling was conducted using AMOS ver. 23.0 to investigate the longitudinal reciprocal effects between mothers' depression and children's emotional problems. The results indicated that both mothers' depression and children's emotional problems were relatively stable between the ages of 4 to 5. There were significant cross-lagged effects from the mothers' depression to children's emotional problems and from children's emotional problems to mothers' depression. Mothers reported higher levels of depression when the children were 4 years old and the children showed more anxiety, depression and emotional reactivity when they were 5 years old. Emotional problems when the children were 4 predicted greater depression among mothers 1 year later. We also examined the group difference (between boys and girls) in the study model. Gender differences were not statistically supported. The results suggested that early assessment and intervention for mothers' depression and children's emotional problems are essential for a healthy mother-child relationship and later child outcomes.

Despite previous literatures suggesting the co-occurrence of substance abuse and behavioral addiction, their relationship has not been systematically explored. Especially, college students are a high risk group for alcohol use and gambling activities and they have various psychosocial problems due to addictive behaviors. This study aimed to empirically examine that drinking problems predict gambling problems among college students. A total of 455 college students who experienced drinking and gambling completed a survey. Logistic regression analysis were performed. After adjusting for demographics and family related variables, drinking problems predicted the occurrence of problem gambling. Implications for social work practice, policy planning and research area on addiction are discussed.

Participants in this study were 1.245 4th and 5th graders and their parents from 8 elementary schools in Seoul, Daejeon, and Pusan. Using the Korean Youth Self-Report (K-YSR), children's behavior problems were measured and assigned to either clinical or normal groups. Between group differences were that the educational level of mothers of internalizing girls was lower than that of normal girls. Girls with internalizing problems had more siblings than normal girls. Parents of both boys and girls with either internalizing or externalizing problems were more rejecting and/or permissive than parents of children without behavior problems. Fathers of children with behavior problems perceived more marital conflicts, while mothers whose children have behavior problems had more negative family-of-origin experiences compared to parents of normal children.

The purpose of this study is to measure the overall level of consumer consciousness and behavior environmental problems of college women students and to analyze influencial factors. Five hundred and sixteen college women students were selected randomly, in Kwangju area. The methods of data analysis were Frequency Distribution, Mean , Percentile, one-Way ANOVA , Scheffe-test . Pearson's Correlation, and Stepwise Multiple Regression Analysis. Major finding are as follows; 1) The consumer consciousness and behavior an environmental problems of college women student showed significant differences according to the grade, age, major, socio-economic status, consumer education experience environmental problems, and frequencies of contacting mass media. 2) The consumer behavior on environmental problems of college women students had a positive relationship with consumer consciousness on environmental problems. Based on the above findings , this study suggests the followings; first the consumer education as a formal program is needed for the improvement of the consumer consciousness and behavior of college women student. Second. The content of the consumer education must emphasize more clearly the consumer rights in order to improve consumer's consciousness and behavior of environmental problems. Third. mass media of TV, radio, newspaper, magazine must be more active publicity and instruction in order to improve consumer's consciousness and behavior on environmental problems.

Purpose: Workers with chronic health problems find it difficult to maintain their work because of socioeconomic difficulties. The purpose of this study was to evaluate the relationships between physical, ergonomic, and mental health hazards in the workplace and chronic health problems of Korean workers. Methods: A total of 28,807 wage workers participated in the study and were selected using the Fifth Korean Working Conditions Survey (2017). Multiple logistic regression analysis was used to determine the associations between physical, ergonomic, and mental health hazards and chronic health problems. Results: Of the participants, 1,220 (4.23%) had chronic health problems. Even after adjusting the general characteristics, vibration, noise, high temperature, low temperature, dust, chemical and cigarette smoke, fatigue and painful posture, dragging or pushing or moving of heavy objects, repetitive hand or arm movements, working with a computer or smartphone, use of internet or e-mail, and anxiety situations increased the risk of chronic health problems. Conclusion: The study reaffirms that exposure of physical, ergonomic, and mental health hazards in the workplace significantly increases the risk of chronic health problems.
