The purpose of this study was to find out the effects of education for prevention of child sexual abuse (rape, sexual assault, sexual harassment etc.) of children in elementary school students. Incidences of sexual abuse in Korea is ranked 3rd in the world. Sexual abuse of children, particularly, is one of the most serious crimes that affect both the victimized children and their family. The issue related to sexual abuse of children has been ignored, and there is a lack of systematic education to prevent sexual abuse of children either for children or their parents. Furthermore, lack of knowledge and poor attitude of teachers limit their capability to provide education for sexual abuse prevention to the children. The education for teachers may change their knowledge of the sexual abuse and their attitude toward it and improve their capability in helping children. 223 Korean elementary school students participated in this study. Research design was One group pretest-posttest design. The education given to the subjects included 4 hours through the multimedia CD-ROM on the prevention of child sexual abuse. The education program was developed based on a survey. School- aged- children, parents, and teachers were interviewed to reveal their educational needs based on their experiences related to sexual abuse. This program includes such as safety education, crisis management, resource person(s), and phone numbers of available hospital. Data was collected before, during and after the education was given to the subjects, to assess their knowledge and attitude toward child sexual abuse. Two instruments were used in this study. Using Cronbach's ALPHA validity and reliability of 2 instruments were tested. The analysis of the data was done with Window SPSS 10.0 for descriptive statistics, t-test and ANOVA. The results of this analysis were as follows : 1. After education, the score of school nurses knowledge was higher than before(t= -4.677, p=0.000). 2. After education, the score of school nurses attitude was not higher than before (t=0.131, p=0.896). The findings from this study will provide an intervention strategy for prevention of sexual abuse in children.

The purpose of this study was to develop various nutrition education materials, including an animated CD, for day care center children and their teachers and in order to apply the nutrition education programs systematically. We evaluated the effect of the nutrition education programs on nutrition knowledge in the first year, and the effect of the nutrition education programs on nutrition knowledge, food attitudes and eating behaviors in the second year in day care center children. In the first year, nutrition education foundational materials, such as the animated CD-ROM, videotape, textbook, panels, posters, slogans, leaflets, picture disks, hand puppets, stickers for compensation and poster boards were developed. The subjects were 537 children (286 boys,251 girls) aged four to six years. In the second year, nutrition education materials, such as the animated CD-ROM and textbook were developed. The nutrition education group included 368 children (177 boys 191 girls) aged four to six years, and the comparison group consisted of 108 children (54 boys,54 girls) Regarding the nutrition knowledge test results in the first year, the pre-test mean of children was 6.82, however, the post-test mean was 11.35 and showed a significant increase (p < 0.001). Regarding the nutrition knowledge test and the food attitude test results in the second yew, the nutrition education group had significantly higher scores than the comparison group in a post-test (p < 0.001). For the eating behavior test results, the post-test means between the comparison group and the nutrition education group were not significant. The test results show that several months of nutrition education is not enough to improve eating behaviors. As a result, nutrition education has improved nutrition knowledge and food attitudes in day care center children but short-term nutrition education was not sufficient to induce a change in eating behaviors. To improve eating behaviors in day care center children, nutrition education programs must be applied to day care center children in addition to their Parents and Persistent education will have to be continued.

ICT(Information & Communication Technology) 활용 지리수업을 위해서는 데이터베이스(database, 이하, ‘DB' 라 칭함)형 교수-학습 자료를 개발하는 것이 필수적이다. 이러한 DB형 교수-학습자료는 WBI(Web Based Instruction. 웹기반수업)에서의 지리이미지자료 사용상의 문제점을 극복해 줄 대안으로 간주된다. 이를 위하여 본 구에서는 우선 지리이미지 데이터베이스 프로그램(이하. '지리이미지 DB 프로그램' 이라 칭함)을 기반으로 CD-ROM 형태의 지리이미지 전자사전(이하, 'GEO-DB' 라 칭함)을 제작했다. GEO-DB에는 3,060개의 지리이미지가 원자료로 수록되어 있는데, 이러한 자료들은 온라인과 오프라인 상에서 교사와 학습자가 공동으로 수집한 것이다. GEO-DB에는 교사와 학습자 모두 지리이미지 자료를 단순하게 활용함은 물론. 임의적으로 자료의 가공이 가능하도록 포트폴리오 기능을 첨부했는데, 이러한 포트폴리오 기능은, 특히 학습자의 자기주도적 학습능력의 신장에 기여하고자 한 것이다 GEO-DB는 사용의 수월성, 검색의 신속성 및 확장의 무한성을 갖고 있어서, 지리 교수-학습에서 ICT의 활용 가능성을 극대화시켜 줄 수 있고. 학습자의 지리학습능력의 신장과 지리학습태도의 변화에 크게 기여할 수 있는 것으로 교사와 학습자에 의해 평가되었다.

We study the characteristics of airflow and sound noise induced by disk rotation in optical disk drives. The characteristics of airflow around a rotating disk surrounded by various tray structures are numerically investigated using a commercial CFD program and then compared with experimental results. Sound pressure and intensity caused by the fluid-structure interactions in the CD/DVD-ROM drive are measured, and the effect of the ariflow on the sound noise and disk vibration is discussed. In order to reduce airflow-induced noise and vibration around the rotating disk, tray geometry is modified. Both numerical and experimental studies implemented with different tray models show that the improved tray model alters the characteristics of the disk-induced airflow, causing the reduction of the airflow-induced sound level.
