The aim of this study was to evaluate the status of consumption and consumer satisfaction of dietary fiber supplements. The survey was conducted using a self-recorded questionnaire developed to meet the purpose of this study. The characteristics of the subjects who have taken dietary fiber supplements in the past are as follows: distributions of socioeconomic variables showed that the highest-ranked group(the group that reported the highest consumption of dietary fiber supplements) was professionals with a college degree or higher degree. In addition, the highest-ranked group were the most healthy, nonsmokers and reported drinking habits of ‘1～2 times/week’. Regarding the health status of those surveyed, digestive disease and constipation were the most common complaints. The majority responded with ‘health concerns’ to the question that asked the reason for their purchase of the dietary fiber supplements. Three major places respondents could find dietary fiber supplements were ‘through the internet’, ‘the market’, ‘the pharmacy’ in descending order. The compositions of dietary fiber products varied. ‘konjac’, ‘cellulose’, ‘psyllium husks’ were the most popular components consumed by the subjects. The average duration of product consumption was less than one month. In terms of satisfaction levels(satisfaction was ranked from 1 to 5), ‘taste’ and ‘type’ scored the highest in satisfaction levels while ‘price’ ranked the lowest. When subjects were asked about self-awareness regarding the physiological efficacy of dietary fiber supplements, the responses were positive in ‘bowel movement’ and ‘weight loss’. Further research is required to improve the quality of dietary fiber supplements in order to assist consumers in selecting the appropriate products.

Purpose: The purpose of this study was to investigate the effective learning method of non-dominant hand for the sequential timing performance. Methods: Twenty right-handed undergraduate and graduate students were randomly assigned to the non-dominant hand practice group that practiced with only non-dominant hand or the bimanual practice group that practiced with both hands simultaneously. The participant was asked to alternatively press two buttons six times with the index finger of the non-dominant hand or both hands in order to reproduce accurately the goal rhythm pattern (3,600ms in total duration). The goal rhythm pattern had three rhythm types and two perceptual structures, which the (in)congruent structure was that the structure of auditory signal was (or not) in accordance with that of visual signal. Results: Bimanual practice group was more effective for absolute-timing learning than non-dominant hand practice group. Although absolute timing performance improved in congruent structure during acquisition phase, the learning effect on absolute timing was occurred in incongruent structure. Relative timing performance of two groups improved in congruent structure during acquisition phase, but the learning effect on relative timing was occurred in both perceptual structures. Conclusion: We suggest that practice methods should be applied differently for absolute timing or relative timing, and the possibility of improving the learning effect of a non-dominant hand by utilizing an incongruent structure of visual-auditory information.

본 연구는 기호를 활용한 인지학습기반 표현움직임 프로그램의 현장 적용성을 탐색하는 것에 그 목적을 두고 있다. 먼저 인지학습 기반의 표현움직임 프로그램 구성에 활용된 Motif Writing 기호를 소개하여 전반적인 이해를 돕고자 하였다. 그리고 남 여 구분 없이 4-5세 유아 실험집단(9명)에게 이 연구를 위해 개발된 움직임교육 프로그램을 8주 동안 적용하는 현장 실험을 실시하고, 인지수업(영어), 신체활동수업 (발레), 스포츠 활동수업(수영) 각 9명씩 총 36명으로 이루어진 집단과 비교하여 다중지능에 있어서의 상대적인 변화를 살펴보았다. 분석 결과, 대인관계, 신체지능을 제외한 언어, 논리-수학, 공간, 음악, 개인 이해지능에서 비교집단보다 상대적으로 유의미한 향상이 나타났다. 이러한 결과는 기호를 활용한 인지학습기반 표현움직임 프로그램이 기호를 읽고 해석하고 자신의 생각을 움직임으로 표현하는 과정을 통해 다중지능의 전반적인 향상에 긍정적으로 작용한 것으로 보인다. 이는 본 프로그램이 단순히 신체적 발달뿐만 아니라 인지적, 정서적 발달에 이르는 전인적 교육 프로그램의 발전적 대안으로 활용될 수 있음을 확인함으로써, Motif Writing 기호를 활용한 표현 움직임 프로그램의 현장 적용 가능성을 시사해 주는 것이다.
