This study was conducted to examine the mediation effect of narcissistic personality traits and schizophrenic personality traits on the relationship between smartphone addiction and relational aggression of middle school girls. Data from 378 girls in Kyungki and Chungchoeng areas were analyzed. Main results were as follows. First, smartphone addiction showed significant positive correlations with narcissistic personality traits, schizophrenic personality traits and relational aggression. Both personality traits also showed positive relationship with relational aggression. Second, narcissistic personality traits fully mediated the relationship between smartphone addiction and reactive relational aggression. Third, schizophrenic personality traits partially mediated the relationship between smartphone addiction and relational aggression. Finally, clinical implications for adolescent girls at high risk of smartphone addiction and suggestions for future studies were discussed.

This study aimed to investigate how teacher's attitude toward violence affect students who experienced bullying victim in their role in making peer-to-peer violence deepen, and how students who experienced the bullying victim react to show aggression, and the aggression is blocked by teacher's attitude toward violence, resulting in decrease of doing the bystander's negative behavior. By conducing this study, this study ultimately aimed to ensure that the teacher's attitude toward violence is very important in preventing peer bullying in the classroom. To achieve this aims, this study conducted a survey of 820 fourth, fifth and sixth graders in 40 classes at 10 elementary schools and limited only 365 of the respondents who reported experiencing peer bullying victim. This study utilized the structural equation modeling method to analyze the data. The results were as follows. First, it showed that the lower the bystander's negative behavior in victims who experienced peer bullying, and the lower the responsive aggression reacted from the peer bullying, when the teacher shows an unacceptable attitude toward violence. Teacher's attitude toward violence also appears to affect peer bystander's negative behavior by mediating peer bullying victim's reactive aggression, indicating that the teacher's attitude toward classroom violence may reduce the aggression of students from the experience of victimization, and consequently prevent the classroom from becoming more leprosy by reducing peer bullying.

In order to verify the effectiveness of the tea culture treatment program to mitigate the relative aggressiveness, the research will target 10 women aged 70 or older who use the P City-based Senior Citizens' Day Care Center to apply the tea culture treatment program to alleviate the relative aggressiveness of the elderly and examine its effects. As a result of the analysis, the score of reactive relational aggressiveness and leading relational aggression is 0.21 lower than the pre-exam average, indicating that the leading relational aggression of the elderly who participated in the tea culture therapy program is reduced than before the program. Based on these analysis results, practical suggestions were made for alleviating aggression among senior citizens using the Center for the Elderly.

Suicide is a behavior that is intended to cause death by itself and requires medical treatment, resulting in suicidal attempt or completion. Suicide causes loss of life, damages the body, costs a lot of medical expenses, and causes families to fall into sorrow and suffering therefore this suicide is a huge loss to family and society. There have been attempts to reduce and prevent suicide by understanding the mechanism of suicide. The mechanism of suicide can be thought of as psychological mechanism and biological mechanism. In the past, if we considered the psychological and biological mechanisms separately, the development of neuroscience now connects and integrates these two. Psychological factors affect biological factors and biological temperaments also affect perception or thinking about the situation and increase psychological vulnerability. Distant factors in suicidal behavior-such as childhood adversity and family and genetic predisposition-increase the lifetime risk of suicide. They alter the response to stress and other processes through changes in gene expression and regulation of emotional and behavioral characteristics. Distant factors affect the biological system and consequently changes in these systems can increase the risk of suicide. In other words, the distal factor does not directly induce suicidal behavior but rather acts indirectly through developmental or mediating factors. These mediating factors are impulsive aggressive and anxious trait, and chronic use of substances. The mechanism of this disorder is the abnormality of the serotonin system and the abnormality of the lipid level. Proximal factors are associated with the onset of suicide events and include changes in the major neurotransmitter systems, inflammatory changes, and dysfunction of glial cells in the brain. A series of studies, including a variety of research methods and postmortem and in-vivo imaging studies, show the impairment of the serotonergic neurotransmitter system and hypothalamic-pituitary-adrenal axis stress response system for suicidal behavior. These disorders lead to suicidal behavior due to difficulty in cognitive control of mood, pessimism, reactive aggression, abnormality in problem solving abilities, excessive response to negative social signals, severe emotional distress, and cognitive dysregulation of suicidal ideation.

Objective : Gastritis refers to an inflammatory disease of the gastric mucosa. Alcohol is one of the main aggression factors, causing bleeding and inflammation in the gastric mucosa and it is known to not only increase lipid peroxide levels, but also deplete key antioxidant factors. The purpose of this study was to determine the effect of Uncariae Ramulus et Uncus water extract (URW) in alcohol-induced gastritis. Methods : The total polyphenol and flavonoid contents of URW were confirmed through an in vitro experiment. Also, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging activity and ferric reducing antioxidant power (FRAP) activity were confirmed. For in vivo experiments, mice were divided into 4 groups (n=8). Also, 1 hr after oral administration of each drug, 50% ethanol was orally administered to induce gastritis. Results : As a result of in vitro experiments, URW showed excellent antioxidant activity. In alcohol-induced gastritis, URW alleviated the damage to the gastric mucosa caused by alcohol. Also, URW decreased reactive oxygen species (ROS) and malondialdehyde (MDA) levels in serum and gastric tissues, and significantly decreased the expression of NADPH oxidases in gastric tissues. In addition, it significantly modulated the nuclear factor erythroid-derived 2-related factor 2 (Nrf2) and nuclear factor-𝜅B p65 (NF-𝜅B) pathways as well as significantly increased the expression of anti-inflammatory proteins. Conclusions : These results suggest that URW not only reduces oxidative stress through excellent antioxidant activity but also relieves gastric mucosal inflammation as a regulator of Nrf2 and NF-𝜅B pathways.
