The present study examined the effects of child maltreatment and self-control on reactive aggression amongst middle-school students and investigated whether students' self-control had any form of moderating effect on the relationship between child maltreatment and reactive aggression. The participants of this study consisted of 482 students (204 boys and 278 girls) from four middle schools located in Seoul and Gyoung-gi province. The Peer Conflict Scale (Marsee, Kimonis, & Frick, 2004) was used to measure the level of reactive aggression. The level of child maltreatment was assessed by means of the Child Trauma Questionnaire (Bernstein & Fink, 1998). Self-control was measured by the Self-Control Scale (Nam, 1999). Statistical analyses of data used for this study comprised the following methods; frequency, mean, standard deviation, and hierarchical regression. The moderating effect of self-control was analyzed by using the procedures proposed by Baron and Kenny (1986). The results indicated that the level of child maltreatment increased the level of reactive aggression whereas the level of self-control decreased the level of reactive aggression. In addition, self-control moderated the influence of child maltreatment on student's reactive aggression. As a result, the influence of child maltreatment upon reactive aggression was greater when the level of self-control was low, compared to when it was high.

The purpose of this study was to examine the effects of interaction based mother-child art therapy on the change of child and mother's interactions in a child who was in trouble due to attachment problems. The subject in this study was a six-year-old child who faced difficulties in peer relationship building and who were maladjusted to kindergarten because of unstable attachment and negative feedback from his parents. Also, he showed serious problem behaviors at home. The ABA design was adopted among single-subject research designs, and the Target child was observed in the sessions in terms of the subfactors of Marschak's Behavioral Rating Scale to gather data related to the changes of child and mother's interactions. As a result of analyzing the collected data, there were positive changes in all the subfactors that were the child's verbal/nonverbal interactions, the mother's verbal/nonverbal interactions and mother-child interactions. Therefore the interaction based mother-child art therapy that was designed to boost child and mother's interactions was effective at furthering the mother-child interactions of the child with attachment problems.

Over the last 20 years there have been more than 3000 peer-reviewed papers relating to climate change and biodiversity published, and still the numbers are increasing. However, most studies focused on the impacts of climate change at population or community levels, and the results invariably reveal that there has been, or will be, a negative effect on the structure and pattern of biodiversity. Moreover, the climate change models and statistical analyses used to test the impacts are only newly developed, and the analyses or predictions can often be misled. In this review, I ask why an individual's life history is considered in the study how climate change affects biodiversity, and what ecological factors are impacted by climate change. Using evidence from a range of species, I demonstrate that diverse life history traits, such as early growth rate, migration/foraging behaviour and lifespan, can be shifted by climate change at individual level. Particularly I discuss that the optimal decision under unknown circumstance (climate change) would be the reduction of the ecological fitness at individual level, and hence, a shift in the balance of the ecosystem could be affected without having a critical impact on any one species. To conclude, I summarize the links between climate changes, ecological decision in life history, the revised consequence at individual level, and discuss how the finely-balanced relationship affects biodiversity and population structure.

This article is to investigate the possibility that project-based classes introducing mobile phones can replace the monotony of traditional classes led by teachers as well as they can encourage students to take active part in the classes to some extent. The students in groups choose a genre for their own video projects (e.g., movie, drama, news, documentary, and commercial) and produce the video contents using a mobile phone for presentation made at the end of a semester. In the sense that the students are allowed to do video-based mobile phone projects, they can work independently outside of class, where time and space are more flexible and students are free from the anxiety of speaking or acting in front of an audience. A mobile phone project consists of around five stages done both in and outside of the classroom. All of these stages can be graded independently, including genre selection, drafting of scripts, peer review and revision, rehearsals, and presentation of the video. Feedback is given to students. After the presentation, students filled out a survey questionnaire sheet devised to analyze students' responses toward preferences and level of difficulty of the project activity. Finally, proposals are made for introduction of a better mobile phone-based project classes.

The purpose of this study was attempted to analyze the relationship between drug abuse and the other problem behavior Patterns among high school students in Cheju. In order to achieve these set-goals, questionaires were finally supplied to the total 379 case of 9 high school from October to December, 1990. The collected data were processed using the SPSS-X computer program and statistically analyzed by the Chi-square method and. percentage. Results of the study were as follows: Among the 370 adolescents, 32.4% of students experienced cigarette smoking in their life, adolescents who experienced alcohol drinking were 46.8%, 0.5% of the students ever used marihuana; cocaine 0.3%, stimulant 3.2%, hallucinogen and inhalants 0.5%, tranquilizer 1.4%, analgesics 31:6%, antitussives 6.5%, antihistamines 1.9%. And all students never experienced the amphetamines and narcotics. The rates of drug use except stimulant and antitussive were higher in the male than in the female students. For the analysis of personal identifying datum, the rates of experienced smokers increased among groups of buddhist and the rates of experienced alconoi drinking increased among groups of no religion. Drug abuser increased among the group lower socio-economic status student, the adolescents whose parents have traditional education point of view. And it was also higher in those who were living only one than in those who were living together. Most students tended to use drugs after 17 or 18 years old. Drug users were more inclined to commit other problem behaviors when compared non-drug users. In the conclusion of the above results, it will be necessary to investigate the drug problem of adolescent. Drug abuse of students must be seen in an environmental context including family, school, peer group and society and not solely as the characteristics of an individual adolescent. And their parents and teachers must be on the alert for the behavior changes of their children such as changes of school performance, neglecting homework, tardiness or truancy from school, runaway from home, and mingled with bad companions, etc. We must recognize that drug abuse is frequently symptomatic of problems in the adolescent's environment.

Purpose: The purpose of this study was to review primary research exploring the correlations between the levels of serum testosterone and the prostate-specific antigen (PSA) in healthy men without prostate diseases. Methods: An integrative review was conducted using the Whittemore & Knafle (2005) framework. The keywords, 'testosterone & prostate-specific antigen', 'testosterone & PSA' and 'healthy men' were used to search peer-reviewed publications in six databases. Among 1,959 searched articles, eleven articles were selected after excluding articles that do not meet inclusion criteria. Literature quality was moderate (Level 3). Results: As a result of this study, it was confirmed through the nine articles that healthy adult men showed no significant correlation between the serum testosterone and the PSA. Conversely, two articles presented that the serum PSA correlate positively with the testosterone. In particular, it is inferred that the effect of the serum testosterone and the PSA secreted into a 24-hour circadian rhythm with different amplitudes and slopes would have had great influence. However, it does not consider the factors affecting the testosterone and the PSA, such as race, liver disease, and BMI, so there is insufficient empirical data to clearly explain the relationship between the testosterone and the PSA. Conclusion: The correlation between the serum testosterone and the PSA in healthy adult men is insignificant in relation to the circadian rhythm of the testosterone and the PSA secretion. It is that a large-scale study including various influencing factors using new biochemical indicators such as pro PSA be conducted in the future.
