Objectives: Students' life changes substantially as grade increases. It implies that risk factors that trigger students' smoking may not be consistent across grades. Most previous studies on student smoking have considered grade simply a control variable. This study examines which and to what extent risk factors are differently associated with smoking initiation according to grade level among high school students in Korea. Methods: Data from the Korean Youth Risk Behavior Web-based Survey (KYRBWS) conducted by the Korea Centers for Disease Control and Prevention (KCDC) in 2007 and 2008 were analyzed in this study. Results: Among boys, school location, school type and pocket money etc. significantly influence smoking initiation in the first grade than in any other grades, but the strength of the association decreased as grade increases except academic performance. Among girls, most independent variables were associated with smoking initiation in the second grade except school location, pocket money per week and academic performance. Conclusions: Our results suggested that the variables related smoking initiation in Korean high school students were notably different by grade and gender. These findings can serve as the basis of policy recommendations with regard to school efforts to prevent student smoking.

Since obesity has been a crucial issue regarding children's health in Korea, numerous studies have been conducted. However, it is difficult to locate studies that can help researchers and/or medical professionals who want to study behavioral differences between obese and normal weight (non-obese) children. The collected literature about obese childrens behaviors were accumulated by performing 'key word' searches from several web engines: 'obesity' 'children obesity' 'behavior' 'habit' 'eating behavior or habit' 'exercise' 'physical activity' and 'daily behavior'. The information was extracted and the behaviors were reviewed utilizing 30 papers that revealed any differences from normal weight children with at least p .05 level of significance. According to those studies, the obese children tended to skip meals more often as a method of losing weight. They also have an increased appetite, eat larger portions and rarely leave food on their plates. The obese children prefer to eat high fat, high calorie foods and eat faster than their normal weight counterparts. Also, the children usually eat alone and eat at irregular meal times. Beside the behaviors related to the standard three meals a day, obese children have high preferences for snacking. The children reported that with pocket money they usually eat certain types of snacks without parent approval. The children stated that they exercise more on a regular basis. However, when asked about their participation they were not likely to engage actively. Meanwhile, they tend to spend free time doing sedentary activities such as watching TV or playing on the computer. Since these studies used self -reported questionnaires with a small sample, size there may be difficulty in forming a basis about obese children's behaviors. Nevertheless, these findings are in accordance with other studies conducted in local as well as western countries. In conclusion, obese children have different daily behaviors or routines from normal weight children. It is recommended that altering these behavioral patterns to match those of normal weight children should be encouraged.

상호작용적 성격을 갖는 통신서비스의 수요확산패턴은 네트워크 효과에 기인한 임계 가입자 규모에 상당한 의존을 보이고 있으며, 이로 인한 통신서비스의 지연 확산 시기 현상이 발생하고 있다. 그러나 통신망이 회선교환망에서 패킷교환망으로 빠르게 진화하고 또한 다양한 패킷기반 서비스들이 개발, 제공됨에 따라 이러한 통신서비스의 확산 패턴 상의 특성은 변화하고 있다. 내구재를 대상으로 수요 확산 패턴을 분석한 기존 연구들과 국내 6개 회선기반서비스 그리고 역시 6개 패킷기반서비스의 확산 패턴을 비교 분석한 결과, 기존 회선기반서비스들에서 보인 지연 확산 시기 현상은 존재하지 않았으며. 뿐만 아니라 다른 내구재들의 초기 확산보다 더 빠른 확산 속도를 보임으로서 오히려 빠른 확산 시기 현상이 발생하고 있음을 발견하였다. 이러한 결과를 바탕으로 향후 신규 통신서비스 확산 전략은 기존의 통신서비스 보급 및 확산을 위한 초기 단계에서의 촉진전략에서 성장 단계의 확산 유지 및 확대 전략이 보다 유용한 전략임을 제시하였다.
