Purpose : Baby-walkers are used by many parents because of the convenience they provide in keeping children occupied, quiet, happy, and in stimulating ambulation. But, these devices have more risks than benefits. Therefore, we performed a study to evaluate the effects of baby-walkers on motor development of human infants according to the hours used in a day, total duration(months), and types of injuries associated with the walkers, and to establish effective methods. Methods : 1,045 questionnaires were filled out by parents who had a baby whose aged between 8 months and 15 months that visited local pediatric clinics and medical centers in Chonju and Iksan from May 1, 2002 to July 31, 2002. They were analyzed in a control group that didn't use babywalkers, a low-user group that used baby-walkers less than 2 hours a day and a high-user group that used them more than 2 hours a day. Results : The mean age of the 1,045 babies whose parents responded to the question investigation was $12.6{\pm}2.4$ months. The number of babies who used the baby-walkers were 811(77.6%). Crawling and walking alone were delayed in the high-user group. The parents who knew the side effects of the baby-walkers totalled 392(48.3%). Conclusion : The findings of this study revealed that many parents didn't know the effects of baby-walkers on motor development in their infants and the risks associated with baby-walkers. Therefore, we should educate parents on the risks of baby-walkers and recommend reducing the use of baby-walkers.

본 연구의 목적은 노인 대상자에게 소도구 운동 후 적용한 전기치료가 노인의 균형 능력에 어떠한 영향을 미치는지 알아보고자 하였다. 34명의 노인을 대상으로 소도구 운동군(n=16), 소도구 운동과 전기자극군(n=18)으로 무작위로 설정하였다. 두 군은 1주일 5일 20분씩 5주 동안 각 군의 운동 프로그램을 진행하였다. 모든 대상자는 사전 사후에 균형 측정하였다. 연구 결과 군간 비교에는 유의한 차이를 보이지 않았지만, 군내 변화는 유의한 변화를 나타내었다. 전기자극이 노인의 균형능력을 높이는데 있어 영향을 줄 수 없다고 판단된다. 하지만 각 군의 평가 결과를 통해 소도구를 통한 운동은 노인의 균형능력 발달에 긍정적 영향을 미친다고 생각된다.

This study investigated elementary students' understanding of Earth revolution and its accompanied apparent motion of constellation in terms of spatial reasoning. We designed a set of multi-tiered constructed response items in which students described their own idea about the reason of consecutive movement of constellations for three months and drew a diagram about relative locations of the Sun, the Earth, and the constellations. Sixty-five sixth grade students from four elementary schools participated in the tests both before and after science classes on the relative movement of Earth and Moon. Their answers to the items were categorized inductively in terms of transforming frames of reference which are observed on the Earth and designed from the Space-based perspective. We analyzed those categories by the levels of spatial reasoning and depicted the change of students' levels between pre/post-tests so that we could get an idea on the preliminary developmental pathway of students' understanding of this topic. The lower anchor description was that constellations move around the Earth with geocentric perspective. Intermediate level descriptions were planar understanding of Earth movement, intuitive idea on constellation movement along with the Earth. Students with intermediate levels did not reach understanding of the apparent motion of constellations. As the upper anchor description students understood the apparent motion of constellations according to the Earth revolution and could transform their frames of reference between Earth-based view and Space-based view. The features as the case of evolutionary learning progressions and critical points of students' development for this topic were discussed.

The study was to examine the effectiveness of the educational program for the parents of autistic children in promoting the development and amelioration of psychopathology. Behavioral pathology and developmental function of autistic children of two parent groups, parents who participated in educational program and parents who did not participate in that program, were compared before and after partent education program. For these purpose, the data were collected from 30 subjects(15 for participant group and 15 for non-participant group) who were diagnosed as Autism according to DSM-III at Child-Psychiatry of Seoul National University Hospital during May 16, 1987 through April 30, 1988. Pre and post tests by Schopler's Psycho-Educational Profile scale were performed for all of the subjects and the data were analyzed by Wilcoxon Rank Sum test, Wilcoxon Sign Rank test and $X^2-test.$ The results obtained were as follows ; 1) The autistic children of participant group were significantly higher than those of non-participant group after education on Imitation, Gross motor and Eye-hand Integration scale of developmental function area (p<0.05) 2) After education, the autistic children of participant group were significantly improved in Affect and Language scale of behavioral pathology area (p<0.05). 3) After education, the autistic children of participant group were significantly improved in developmental function, such as perception, Fine motor, Gross motor, Eye-hand Integration, Cognitive Performance, Cognitive Language (p<0.05). 4) The autistic children of non-participant group were significantly improved in Relating behavior and developmental functions such as Perception, Fine motor and Eye-hand Integration at post test in comparison to pre test (p<0.05). From these results, it might be concluded that the autistic children of participant group were improved much more, and obtained higher score in developmental function area than those of non-participant group. It is suggested that this kind of education program helped and supported the parents to do some more appropriate approach for the development of their children.
