The purpose of this study was to identify the persistent and dynamic association between bullying and victimization. Gender differences in patterns of school bullying was hypothesized based on the literature. Analysis were based on waves 3-6 of the Korea Children and Youth Panel Survey, a nationally representative data of primary and secondary school students in South Korea (N = 1,881). Autoregressive cross-lagged model was employed to identify the reciprocal association between bullying and victimization in longitudinal data. As hypothesized, regardless of gender, lagged effects were statistically significant between each time points such that current bullying caused future bullying and current victimization led to future victimization. However, there was no cross-lagged effects of current victimization on future bullying nor current perpetration on future victimization for both male and female youth. Findings from this study may have implications for designing policies against school bulling. Not only is short-term intervention for handling immediate psycho-social maladjustment important, but so are long-term plans that prevent youth from falling into continued perpetration and victimization in the system of school bullying.

This study explored the participant roles and the cross-sectional and longitudinal relationships between interpersonal behavior characteristics and bullying/victimization. The subjects were 4th and 5th grade children and instruments were the Participant Roles Scale, Self-Report Coping Scale, Teenage Inventory of Social Skills, and Social Anxiety/Avoidance. They were contacted again one year later. In the distribution of participant roles at Time 1, defender of the victim was highest, then outsider; at Time 2 outsider was the highest and then defender. There was a tendency of gender difference in distribution of participant roles only at Time 1. Males were more in the group of reinforcer; females were more in the group of defender and victim. There were high positive correlations among bully/reinforcer/assistant scores. In the concurrent view, children who used approach coping strategies and showed higher social skills were more likely to be defender. Children who had lower social skills and higher social anxiety and social avoidance were more likely to be victim. In the longitudinal view, children who had developed higher social skills were more likely to be defender. Children who had employed less approach coping strategies and had showed lower social skills and higher social avoidance were more likely to be victim.

Purpose: The purpose of this study was to investigate differences in the states of anger, depression, resilience and self-esteem according to type of school violence involving elementary school students. Methods: The participants were 257 elementary school students in the 4th, 5th and 6th grades. Data was collected by structured questionnaires, and analyzed using descriptive statistics, ${\chi}^2$-test, t-test, ANOVA, and Pearson correlation coefficients with the SPSS/WIN 20.0 program. Results: There were significant differences among the states of anger (Fs=16.66, p<.001), depression (Fs=18.04, p<.001), resilience (F=12.77, p<.001) and self-esteem (F=10.39, p<.001) according to the type of school violence. Of all the groups, bully-victim exhibited the highest score for anger and depression, and the lowest score for resilience and self-esteem. Conclusion: Based on the findings, developing intervention programs that consider the psychological characteristics of elementary school students is necessary. Also, the results of this study suggest that integrative programs for students that can enhance resilience and self-esteem, such as self-discovery programs, and reduce anger, such as anger control programs, need to be developed.

Purpose: To identify bullying tendencies among elementary, middle, and high school students. Method: A descriptive study was conducted with 911 participating students. Data were collected using three, self-administered questionnaires that had been modified by the investigator. The data were analyzed by the SPSS Win 10.0 program using descriptive statistics, ANOVA. Result: The level of bullying was significantly different among elementary school, middle school and high school students. Middle school students were higher than elementary and high school students. In subtypes of bullying, language type was higher than alienation and physical damage types in elementary, middle and high school students. The methods to resolve a bullying situation are for the victim to 'speak to parents' in elementary school students, but 'bear alone' in middle school and highschool students. The answer to the question 'how many of your friends have been the victim of bullying' was 3-8 friends'. The reason for being a bully victim was 'because they pretend to be a superior man'. Conclusion: Although much research has been conducted in this area, further study among elementary, middle and high school students needs to be conducted. Furthermore, a variety of programs for preventing bullying among elementary, middle and highschool students should be developed.

This study explored the consistency of bullying, victimization and aggressive victimization, the relationships between bullying, victimization and aggressive victimization and overt/relational aggression, and the relationships between bullying groups and overt/relational aggression with gender. The subjects were 4th grade children and 2 years later they were contacted again. Instruments were the Bully-Behavior Scale, the Peer-Victimization Scale and the Peer Nomination Instrument. Bullying, victimization and aggressive victimization were decreased while there were consistencies in overt and relational aggression from 4th to 6th grade. In the correlation analysis, male victims at Time 1 were negatively related to overt and relational aggression at both Time 1 and Time 2. Female bullies were positively related to relational aggression at both Time 1 and Time 2. In the cross-sectional relations of overt aggression with bullying groups, there was a gender difference. In the relational aggression with bullying groups, only bullying groups had a significant difference. In the longitudinal relations of overt aggression with bullying groups, only gender had a significant difference. Males appeared to be more overtly aggressive than females. In the relational aggression, bullying groups, gender, and the interaction between bullying groups and gender had significant differences. Female bullies were more likely to be relationally aggressive than other groups.

This study investigated the relation between participation in bullying, peer relationship and children's social status. We examined the classified types of social status among 700 fifth and sixth grade elementary schools students. The data were obtained by administering a self-reported questionnaire. Differences were identified with participation in bullying behavior, intimacy friendship and peer support as peer relationship. The collected data were subjected to a descriptive and F-test analysis using the SPSS software program. The results conveyed that social status was different according to the gender difference. Rejected boys presented more bully, reinforce, assistant and victim behaviors. Neglected boys were more victims of bullying. Defensive behavior was more apparent in popular and neglected boys. Furthermore, such boys had high intimate friendships. Popular boys presented distinctively more peer support. Rejected boys represented less intimate friendship and peer support. On the other hand, popular girls portrayed more defensive behavior. However, rejected girls and neglected girls had less defensive behaviors. Victim behaviors were less coherent in popular and neglected girls. Intimate friendship and peer support were mostly apparent in popular girls. Rejected boys represented less intimate friendship and peer support.

Text mining (TM) is most widely used to process the various unstructured text documents and process the data present in the various domains. The other name for text mining is text classification. This domain is most popular in many domains such as movie reviews, product reviews on various E-commerce websites, sentiment analysis, topic modeling and cyber bullying on social media messages. Cyber-bullying is the type of abusing someone with the insulting language. Personal abusing, sexual harassment, other types of abusing come under cyber-bullying. Several existing systems are developed to detect the bullying words based on their situation in the social networking sites (SNS). SNS becomes platform for bully someone. In this paper, An Enhanced text mining approach is developed by using Ensemble Algorithm (ETMA) to solve several problems in traditional algorithms and improve the accuracy, processing time and quality of the result. ETMA is the algorithm used to analyze the bullying text within the social networking sites (SNS) such as facebook, twitter etc. The ETMA is applied on synthetic dataset collected from various data a source which consists of 5k messages belongs to bullying and non-bullying. The performance is analyzed by showing Precision, Recall, F1-Score and Accuracy.

Post harvest processes for rice include drying, storage and processing. Drying has a great effect on the quality of the grain. The existing rice centers are with the ill equipped, especially with drying and storage facilities. The rice harvesting has bully mechanized, a large volume of rice with high moisture content are taken to the rice processing complex(RPC). Three, the need for drying and storage facilities becomes more urgent. At present the daily drying capacity of RPC can't exceed over 40~50 M/T. Therefore new technology and facilities for a high quality and main efficient drying should be introduced one such technology is the continuous flow drying system. This research, aims to test performance efficiency the mixed continuous flow grain dryer was whose daily drying capacity is 100 M/T. The results of the performance tests of the dryer are shown as follows; (1) The temperature distribution of the drying modules were measured by a temperature recorder. The fifth module showed the highest value, followed by the seventh and the third. (2) When the intake air temperature was $55^{circ}C$, the drying rates were 1.7 and 2.6%, wb/pass in the exhaust temperatures of 20 and $22^{circ}C$. And when the intake air temperature was $60^{circ}C$, the drying rates were 1.7 and 2.3%, wb/pass in the exhaust temperatures of 22 and $25^{circ}C$. (3) The average increased rate of cracked grains after the drying process was 0.7% which is below the tolerance limit (2.0%) of the continuous grain dryer.

Objectives : The objective of this study was to identify the risky behavior subtypes in adolescents with depression, and the relationship between those subtypes and suicide attempt. Methods : Ninety adolescents who met the Diagnostic and Statistical Manual of Mental Disorders-4th edition criteria for major depressive disorder, dysthymia, or depressive disorder not otherwise specified participated in the study. Participants were interviewed about suicidal attempts, non-suicidal self-injuries. Smoking, drinking behaviors, and searching for the word "suicide" on the internet, negative life events including bulling-bullied experiences, and history of abuse were also included with questionnaires. Results : The results of cluster analysis showed that four risky behaviors were divided into three clusters : non-risky type, characterized by few risky behaviors ; delinquency type, which was characterized by smoking and drinking ; non-suicidal self-injury type. In non-suicidal self-injury type, percentage of girls was higher and clinical symptoms were more severe than delinquency type. In addition, delinquency type members could be a bully, while non-suicidal self-injury type members could be abused by a family member. Logistic regression analysis showed that both risky behavior subtypes were significant predictors of suicide attempt. Conclusion : These results suggest that two types of risky behaviors of depressed adolescents have an effect on the suicide attempts independently. Then, the implications and limitations of the study were discussed and directions for future studies were suggested.
