The aim of this study was to compare the efficiency of sonic and manual toothbrush in decreasing plaque accumulation in young orthodontic patients. Twenty one healthy orthodontic patients attending department of pediatric dentistry at Samsung Medical Center were chosen for the study. The subjects were randomly assigned to either sonic or manual toothbrush and instructed to brush for 2 minutes. Plaque score was assessed with the modified Visible Plaque Index (VPI) before and after brushing. Each brush was repeated twice. A mean plaque reduction of sonic toothbrush was 61.79%(${\pm}7.95$) compared to 69.19%(${\pm}10.08$) of manual toothbrush(p<0.05). With the sonic toothbrush, male presented a mean plaque reduction of 63.07%(${\pm}8.64$) while female presented 60.39%(${\pm}7.30$). For manual toothbrush, male presented 69.33%(${\pm}10.14$) and female presented 69.03%(${\pm}10.55$) reduction of plaque accumulation(p>0.05). There was no statistically significant correlation between age and plaque removal efficacy in this study(p>0.05). Manual toothbrush was significantly more efficient in removing plaque than the sonic toothbrush in young fixed orthodontic patients.

기업가정신이 기업의 혁신 및 국가 경제발전에 중요한 역할을 한다는 인식이 높아지면서 기업가정신교육도 전 세계적으로 확산되고 있는 추세이다(Katz, 2003; Kurako, 2005). 한국 정부는 '창의인재양성'이라는 교육정책 목표로 기업가정신교육 예산이 증가시키고 있으며, 교육 대상자도 대학생 및 성인 대상을 중심에서 중 고등학생으로까지 확장하고 있는 실정이다. 기업가정신교육은 창업가적 스킬을 발전시키고 진로선택에 있어서 도움을 주는 것을 목적으로 하고 있으나(Linan, 2004), 다수의 기관에서는 저마다의 기업가정신에 대한 정의 및 운영방식을 적용되고 있는 것이 현실이다. 일반적으로 대학수준의 프로그램에서는 교육의 효과성을 창업의도(Entrepreneurial Intention)로 측정하고 있지만, 사회에 진출하기에 이른 시기인 청소년에게 그 지표를 그대로 적용하는 것은 적절하지 않다는 비판이 제기되고 있다. 이에 따라, 본 연구에서는 한국에서 운영되고 있는 대표적인 2개의 청소년 기업가정신교육기관의 커리큘럼을 분석하여 청소년에게 적합한 효과성 지표를 제시하고, 두 프로그램의 효과성 결과를 비교분석하여 향후 청소년 기업가정신교육의 발전방안에 대해 제시하였다.

The purpose of this study is to investigate the effects of poverty on the psychosocial adjustment of adolescents. Particularly, this study seeks to examine the mediating effects of neighborhood environments and parental depression. The 2008 'the Korean Youth General Survey' data were utilized. We analyzed data from 2,218 adolescents between the ages of 12 and 18 and their parents. We defined poverty as the income-to-needs ratio, and measured neighborhood environment using the degrees of neighborhoods' disorder, attachment, cohesion, and informal social control. Adolescents' externalizing and internalizing problem behaviors were used as indicators of adolescents' psycho-social adjustment. Structural equation modeling was utilized as the major analytic method. This study found that adolescents in low income families were more likely to reside in disadvantaged and dangerous neighborhoods. More importantly, the results revealed that psychosocial adjustment of the adolescents was indirectly influenced by poverty through the mediators, neighborhood environment and parental depression. Based on the results, we discussed policy and practice implications, including various interventions that may improve parental mental health and neighborhood environment of low income communities.

Girls showed lower level of aggression than boys. 3)Adolescents' aggression was significantly correlated with social support. The more support from friends, classmates, and parents HAs perceive, the less aggression they reported. Though support from peers was correlated significantly only with anger expression, support from parents was correlated significantly with all the components of aggression. And the more support from friends and classmates HAs perceive, the less aggression they reported.

For this study, we collected in-depth interviews with five youth in career moratorium or early discharge from out-of-home care. The results of the study were as follows: we divided into six themes such as "I cannot lean on family of origin", "unstable life", "strayed by wandering and prejudice", "I need someone to rely on", "belated regrets", and "constantly dreaming of resurgence"; and the six themes were analyzed separately in the sub-categories. As a result, we found out that the youth in career moratorium lived a life of regret and recovery in the unstable life journey. Based upon the results, we suggested social welfare practice and policy implications in order to systematically support the NEET youth after discharge from out-of-home-care.
