본 연구는 2005년부터 2006년까지 유아들을 대상으로 생물 기르기 활동을 실시한 현장연구이다. 유아들과 2년 동안 지속적으로 다양한 생물을 길러보고 그 성장과정을 관찰하면서 이 과정에서 나타나는 유아들의 과학적 탐구능력을 분석하였다. 이를 위해 장수풍뎅이, 누에, 명주잠자리 등을 키우면서 통합적 교육활동을 실시하였다. 연구 결과 생물 기르기 활동은 유아의 과학적 탐구능력을 향상시키는 것을 볼 수 있었다. 유아의 연령증가에 따른 탐구능력의 변화과정을 분석해 본 결과 유아의 연령 증가에 따라 관찰력이 좀 더 세밀해지고 관찰을 통한 비교하기, 예측하기 등의 과학적 탐구능력이 향상되는 것을 볼 수 있었다. This study was performed to investigate young children's scientific inquiry by performing integrated activities for raising animate creatures. 30 4-year-old children participated in the study for 2 years. They raised various animate creatures including beetles, silkworms, and ant lions. Children performed various integrated activities around the creatures, such as language, math, science, art, and physical activities. The study result revealed that children became more interested in raising living things and showed higher levels of scientific ability, verbal expression, and creative thinking skills. As time passed by, the children paid more attention to details while they observe and their verbal and graphic expression was based on their factual knowledge and became more sophisticated.

본 연구는 다양한 임목 정보를 측정하고 효과적으로 관리하기 위해 스마트폰 애플리케이션과 웹 애플리케이션 서버(Web Application Server, WAS)를 개발하였다. 수고, 방위, 고도, 경사, 위치 좌표는 스마트폰에 내장된 동작센서를 통해 취득된 각도를 삼각법에 적용하여 측정하였으며, 흉고직경 및 거리는 Google AR Core에서 제공하는 AR API(Application Programming Interface)를 응용하여 측정할 수 있도록 하였다. 웹 애플리케이션 서버는 스마트폰이 측정한 데이터를 수신하여 저장, 조회, 출력하고 수목의 위치를 카카오 맵에 표시할 수 있도록 개발하였다. 또한, 개발된 애플리케이션의 정확성을 평가하기 위해 인공 침엽수림에서 잣나무 90본, 천연 혼효림에서 무작위로 90본을 선정하여 버텍스 및 윤척과 비교하였다. 비교 결과, 흉고직경과 수고 모두 95% 수준에서 유의한 결과를 나타내었으며, 흉고직경의 경우 인공 침엽수림이 평균 0.6745 cm, 천연 혼효림에서는 평균 1.0139 cm의 오차를 보였다. 수고는 인공 침엽수림이 평균 0.6714 cm, 천연 혼효림은 평균 1.3297 m의 오차를 보였다. We developed smartphone application and web application server to acquire and effectively manage tree measurement information. Smartphone applications can measure tree height, diameter at breast height (DBH), azimuth, altitude, slope, and positional coordinates using augmented reality (Google AR core) and motion sensors. The web application server effectively manages and stores measurement information. To evaluate the accuracy of information acquired using a smartphone, 90 Korean pine trees (Pinus koraiensis) were randomly selected from a natural mixed forest, with a total of 90 representative trees randomly collected from a natural mixed forest. Then, height and DBH were measured using a Haglof Vertex Laser Hypsometer and caliper. Comparisons of the results indicated significant results at the 95% level and a very high average correlation of 0.972 for both tree height and DBH. In terms of DBH, the average errors were 0.6745 cm and 1.0139 cm for artificial coniferous and natural mixed forests, respectively.

The purpose of this study was to investigate the short-term motor memory in continuous and discrete modern dance movements. The subjects were 34 students who was majoring in modern dance in P Arts High School. The task of this experiment were 8 discrete modern dance movements and 8 continuous modern dance movements. Subjects twice viewed sequence 8 movements performed by an expert dance, sequence were viewed in one minute and then immediately recalled by actually performing the dance movements. A T-test was used in order to see whether there exists significant difference between the groups. The reuslts are as follows; (1) Both primacy nad recency effects were apparent. (2) The motor memory of dicrete movements were appeared significant differences(p<.01). Experts and over than 5 years dance experience group were greater than novices and less than 2 years dance experience group. (3) There was no significant difference among the groups in the continuous movements.

The definition of anxiety, the way of estimating anxiety, the relationship between anxiety and competition, and anxiety and action have been observed briefly before. Any one who dances has an experience of seeing the stage under lighting in a waiting room or behind a curtain in waiting for his or her turn impatiently. Or, a student or dancer who has been well during practice habitually makes his or her teacher or dance director by forgetting a sequence or staggering loosing his or her balance on stage. Therefore, it is practically very meaningful for dancers who wish the optimal results to grasp and control the source of such a failure successfully. It anxiety comes from his or her own nature, the only way was and is to adjust and control his or her psycological situation. Recently, however, a variety of psychological methods such as progressive relaxation techniques, transcendental meditations, hypnosis, yoga, or biofeedback ar developed, most of which are useful for the dance directors to help students who suffer much from excessive anxiety which is beyond their control. Alternatively, a situation or circumstance imitating that of real performance, contest, or examination can be established so that students practise sufficiently to be familiar with any anxiety to face and to control increasingly their psycological situation by themselves. For better results, seemingly, directors have to monitor the degree of anxiety dancers feel. As discussed briefly before, one of the best solutions for the dancer who is very uneasy when awaiting his or her turn behind stage is to lessen the period of time to await, and, especially, for a young student, the emphasis on the values of improving his or her talent and trying his or her utmost rather than on the importance of result can contribute to allay his or her apprehension. Considering that "anxiety" has a complex and thus important implication, it may not be did to be dealt with sufficiently here. The findings of this study, however, may be useful to suggest some beneficial theories for the dancing education in the future. Dancing teachers are required further to look into psychological aspects relating with actions to perform more scientific and efficient education.

Imagery, called visualization, mental practice, mental rehearsal is a technique that has gained considerable attention in sports and dance in recent years because it is thought to enhance skill performance. In this study, theoretical interpretations of the imagery process and factors influencing imagery are reviewed for further study of imagery. The mechanisms that mediate cognition, imagery and motor movement remain mostly unknown. To gain more academic respect, the research on imagery must use better methodologies and attempt theorizing.

Imagery, called visualization, mental practice, mental rehearsal is a technique that has gained considerable attention in sports and dance in recent years because it is thought to enhance skill performance. In this study, theoretical interpretations of the imagery process and factors influencing imagery are reviewed for further study of imagery. The mechanisms that mediate cognition, imagery and motor movement remain mostly unknown. To gain more academic respect, the research on imagery must use better methodologies and attempt theorizing. In dance, imagery has been used for communication of movement's meaning, inspiration for creation, exprience of movements's effort. So it is necessary for more efficient dance class to study on cues and sources of imagery which must be sophyscated for levels of ability, kinds of movements and class.

The purposes of this study were to investigate the effect of imagery practice by the direct or indirect verbal cues on coupe balance, devant developpe, fouette en tournant and EEG(Experiment Ⅰ), and the effect of imagery practice by the visual-verbal or verbal cues on Italian fouette(Experiment Ⅱ). In experimentⅠ, twenty-seven high school girls who major ;in dance devided into 3 groups. Direct imagery group, indirect imagery group, control group were adapted to perform for 20min/day, 5 times/week during 7 weeks. In experiment Ⅱ, twenty-one high school 해긴 who major in dance divided into 3 groups. Visual-verbal imagery group, verbal imagery group, control group were adapted to perform for 20min/day, during 9 days. In order to see whether there is significant difference among the groups this study used an one-way ANOVA and Tukey tcst. And in order to see whether there is significant difference between pre and post performance scores and EEG of the relax-rest state and the imagery rehearsal state, t-test was used. The results are as .follows: 1. Performance scores of devant developpe, fouette en tournant in direct imagery group and performance scores of coupe balance, devant developpe, fouette en tournant in indirect imagery group were significantly increased. 2. There were no significant differences of performance scores between two experimental groups. 3. In EEG α wave %power of the imagery rehearsal state in direct imagery group were significantly decreased(P<.01). 4. There were no significant differences of β wave %power in the experimental groups. 5. Technical scores of italien fouette in visual-verbal imagery group was increased more than verbal imagery group, but there was no significant difference between two groups. 6. Artistical scores of italien fouette in visual-verbal imagery group was significantly more than verbal imagery group.

A learner can receive various kinds of sensory information, extrinsic feedback about errors from the instructor is one the most critical aspects of the learning environment. This kind of information can have several simultaneous roles ; It can serve as an energizer to increase motivation ; it can reinforce the probability of various future choices ; it can provide information, where it signals the nature and direction of errors and how to correct them ; and it can a learner dependency, where performance suffers when the information is withdraw. Feedback can take on many forms, such as videotape replays, films, and verbal descriptions. The largest errors can be corrected in early learning with frequent feedback. After a few trials, however, learning is best if feedback frequency is gradually reduced across practice.
