Purpose: The aims of this study were to evaluate effects of massage therapy and the attachment promotion program with autistic children. Method: A quasi-experimental design was conducted with a convenience sample of 44 autistic children. The experimental group (n= 23) attended the massage therapy and the attachment promotion program for 4 months. The control group (n=21) only had the attachment promotion program. Measurements were made twice for both groups using the social maturity scale and child autism rating scale. Recording of mother-child attachment was done for 15 minutes in only the experimental group twice using video equipment. Results: After 4 months of interventions, there was significant difference on social maturity (F=9.01, p=.005) between the groups. However, there was no significant difference on CARS ((F=2.47, p=.124). The total scores of mother-child attachment between pre- and post-interventions showed a significant difference (Z=-3.42, p=.001). Conclusion: The results showed that massage therapy and the attachment promotion program might be an effective way for providing a chance to increase social maturation and to increase attachment between mother and autistic child.

정보통신기술의 발달로 인하여 e-learning산업은 급속히 팽창하고 있으며, 이외 함께 제작 기술의 발전도 빠르게 이루어지고 있다. 기존의 동영상 강의 제작의 큰 비중을 차지하던 Microsoft 사의 WMV(Window Media Video) 형식에서 최근에는 다른 동영상 파일에 비해 용량은 작지만 화질이 매우 우수한 포맷인 FLV(Flash video)으로 전환되고 있는 추세이다. 플래쉬 기반으로 이루어진 Flv는 윈도우, 리눅스 이외에도 대부분의 OS 환경과 브라우저에서 구동이 되며, 사용자가 별도의 플레이어 설치나 코덱 설치 과정 없이 재생을 할 수 있어 차세대 표준형, 개방형 플랫폼으로 개발자들의 관심을 끌고 있으나, 아직까지는 기존의 WMV 형식과 FLV간의 용량이나 화질의 비교, 제작시간 등에 대한 정확한 비교 분석에 관한 데이터가 나와 있지 않은 실정이다. 따라서 본 논문은 제작 방식에 따라 WMV와 FLV간의 데이터 비교 분석을 통하여 각기 특성에 맞는 제작 플랫폼을 설정하는데 가이드를 제시하고자 한다.

Effectiveness of the video-record learning method in teaching bowel elimination nursing skill was investigated using an experimental research methodology. Data was collected from 63 female students attending Fundamental Nursing class from a nursing college in Seoul. The subjects were randomly assigned to two groups, one is the experimental group of 29 and the other the control group of 34. The independent variable was video-record learning method and the dependent variable were the degree of knowledge achivement, nursing skill achivement, competence on practicing elimination skill, and satisfaction about the learning method. The hypotheses of the study were as following. 1) There will be significant difference between the experimental group and the control group in dependent variables. 2) There will be significant positive correlations between nursing skill achievement and other three dependent variables-interest in nursing, adaptation in nursing, and preference of nursing job. Data was analyzed using descriptive statistics, chi-square test, t-test, and Pearson's correlation coefficient with SPSS $PC^+$ program. Findings of the study are : 1) There was no significant difference between the experimental group and the control group in knowledge achievement using P<.05. 2) There was significant difference between the experimental group and the control group in nursing skill achievement using P<.05. 3) There was no significant difference between the experimental group and the control group in competence on practicing elimination skill using P<.05. 4) There was no significant difference between the experimental group and the control group in satisfaction about learning method using P<.05. 5) There was positive correlation between nursing skill achievement and the other variables but no significant difference was shown. 6) This study suggests that video-record learning method is an effective learning method for achiving basic nursing skills but is not effective in other areas such as knowledge achivement, competence in performing nursing practice, and satis-faction about the learning method. Further study with more developed research design and statistical analysis should be done to investigate the effectivenes of video-record learning method in learning basic nursing skill more accurately.
