For the purpuse of gathering basic information to develop the education program for parent to become educators of young child for sexual abuse(YCSA) self-protection, 298 mothers of 4- to 6-years old children responded to a questionnaire to measure their needs for YCSA self-protection education and knowledge of characteristics related to YCSA. Results related to the needs of mothers showed that 30.4% of them were educated for YCSA protection and 64.6% had provided YCSA self-protection education to their children. However, it was also found that even mothers who had frequently been educated on protection skills regarding YCSA encountered problems as a result of insufficient information and materials concerning YCSA protection education. The mothers in the study subsequently recommended that from age 4 years young children should be educated about YCSA by parents and teachers together. And most of them expected young children to learn some skills to cope with YCSA, with parent education programs for YCSA also recommended by the mothers. Mothers' characteristics such as knowledge about YCSA, myths and stereotypes toward YCSA showed meaningful correlations with mother's demographic variables, not with children's variables. The study concludes that developing the requested parent education program should be done in consideration of parent's needs and characteristics related to the YCSA self-protection.

This study was conducted to evaluate a forecast model designed to describe a vocational high school for runaway students. The study included 2000 adolescents from the KEEP(Korean Education and Employment Panel). A Data mining decision tree model revealed that: (1) Suicide ideation was a risk factor for running away among smokers. (2) High self-evaluation was a risk factor for running away among individuals that smoked and had no suicide ideation. (3) Drinking was predicted as a risk factor for no smokers, while family life dissatisfaction was predicted as a risk factor among non-smokers that drank. (4) Negative relationship with mother was predicted as a risk factor among non-drinking non-smoking.

The purpose of this study was to assess the effects of a children sexual abuse (CSA) parental training program with applied developmental bibliotherapy on parents. Subjects were 54 mothers, 24 of whom participated in the program which included 8 sessions for 4 weeks. Four dependent variables were subjected to analysis of covariance (ANCOVA); mothers’ knowledge, myths and stereotypes related to CSA, and their children’s levels of prevention concepts comprehension and self-protection skills of CSA. The results showed that the program increased mothers’ knowledge of CSA and decreaesd their beliefs on myths and stereotypes, and also increased their comprehension level of CSA prevention concepts and their level of children self-protection skills. These positive effects of the program show that the program can be incorporated into early childhood education practices. We are also pursuing the development of other research programs on this subject.

본 논문에서는 영상의 소유권 보호를 위해 DCT계수들의 자기유사성(self-similarity)을 이용한 새로운 디지털 워터마킹 기법을 제시한다. 신경회로망 중 SOM(Self-Organizing Map)을 이용하여 유사한 계수를 분류하고 클러스터들 중 선택된 클러스터에 워터마크를 삽입한다. 일반적으로 영상의 고주파 영역에 삽입된 워터마크는 JPEG압축 같은 압축처리에 의해 쉽게 제거된다. 그리고 저주파 영역에 삽입된 워터마크는 영상의 화질을 훼손시킨다. 따라서 중간주파수 영역에서 많은 계수들을 가지는 클러스터에 워터마크를 삽입한다. 이 알고리즘은 선택된 클러스터 내의 계수들의 개수에 따라 워터마크를 영상에 삽입함으로써 영상의 훼손을 줄여준다. 워터마크가 삽입된 영상으로부터 워터마크를 검출하기위해 원영상없이 선택된 클러스터를 이용한다. 실험을 통해 새로 제안된 알고리즘은 영상의 좋은 화질과 JPEG 압축, 필터링과 같은 영상처리, 축소와 학대, 잘라내기 같은 기하학적 변환, 자음과 같은 공격에 아주 강인하다.
