  • The purpose of this study was to identify observation methods, observation targets and their changes in elementary school students' observing aquariums. Silurus microdorsalis, Orthrias nudus, Iksookimia rotundicaudata and Semisulcospira bensoni in two aquariums were observed for 40 minutes in every week during 10 weeks by elementary children. Students' observation methods and targets were analyzed with their observation diary. Also the change of observation methods and targets on each species were analysed based on the observation diary. This study found the facts which was change of observation methods and observation targets according to observable theme of each species as time goes by. The results also found children's various methods and targets in observing living objects and observation methods were changed variously during 10 week-observation. The results of this study may provide more various and systematic norm and assessment criteria for teaching observation.

  • The purpose of this study is to find out learning content for astronomical observation that could perform astronomical programs regardless of weather conditions as a case for the present conditions of astronomical observation and the methods of new education for astronomical observation, and to suggest the methods of synchronized multiple astronomical observation and actual cases using the Internet network. The results are as follows. First, the method of galaxy-oriented astronomical education helped those attempting to approach astronomy academically for the first time grasp useful concepts as to the astronomical space, and let them look at the space in an objective sense, which was effective in forming cosmic structure and concepts. Second, the administration curriculum of astronomical observation team was related to data that systematically contained annual astronomical education concerning the operation of astronomical observation teams; thus, they could be suggested as beneficial teaching materials to the teachers who wanted to organize a school club meeting. Third, it has been noted that the level of students' satisfaction in p2d program and MSO program was very high, and they turned out to be effective learning methods that could be implemented even in times of rain when it would not be possible to conduct astronomical observation activities.

  • This research, which has been planned to appreciate the features of continuous observation of space, has applied the procedure of acquiring continuous visual information when the act of watching takes place along the time to analyze the space characteristics through the scenes and time so that the features of attention shown in the process of acquiring visual information at the time of observing continuous scenes might be estimated. For analysis of the features of continuous observation was set up the premise that the features of observation and perception vary depending on gender, when the women shops in department stores were selected as research objects. The observation features found at the time of continuous observation of selling spaces in department stores were focused on two analysis methods in order to compare the differences and characteristics of the two. The followings are the findings. First, the area with predominant observation was found to be 87.1% in both methods. It was found that the analysis of observation features by "Analysis I" was useful for inter-sectional comparison of continuous images. Second, in case of extracting predominant sections, the ceiling or the structures which are the backgrounds rarely attracted any eyes. Depending on analysis method, there was the gap of 14.3%~25.0% between observed sections. Third, in case that the hall is curved, the eyes were found to be expanded from side to side and up and down. The review of observation numbers of predominant sections makes it possible to decide whether it should be regarded as (1) unstability or (2) expanding search, and when the images are enlarged from distant view to close-range view, the weakening vanishing point results in the increase of expanded search of surroundings. Accordingly, it was found that the characteristics of images has effects on the observation features when any space was continuously observed. Furthermore, the difference of analysis methods also was found to be likely to cause big differences in the results of analyzing observation features.

  • This paper discusses the problem of designing an observation function as coarsest as possible in supervisory control of discrete event dynamic systems. Some algebraic properties of two sets consisting of observation functions for which the given desirable behavior is realizable are investigated:these sets with a partial ordering turn out not to possess largest elements. Two natural methods of obtaining an observation function, which is frequently coarser than the identity mapping, are also presented. An example illustrates the use of these methods.

  • The purposes of this study were firstly to assess the differences of conflict resolution strategies between friends according to children's peer status, and secondly to investigate the relationship of conflict resolution strategies measured by self-report, hypothetical interview, and observation methods. Thirty-four dayds in elementary 5th graders were selected according to peer status and friendship. Collected data were analyzed tv t-test and Spearman's correlation. The results of this study showed that children's conflict resolution strategies differed according to their peer status. Specially, popular children reported using and experiencing compromising/integrating strategies more than rejected children did. Rejected children reported using and experiencing dominating strategies more than popular children did. Secondly, there were meaningful correlations between compromising/integrating and dominating strategies, as measured by self-report, hypothetical interview, and observation methods. However, no relations emerged among avoiding, obliging, and intervention requesting strategies, as measured by self-report, hypothetical interview, and observation methods.

  • The performance of speaker identification is severely degraded in noisy environments. Recently probability weighting method based on observation membership was proposed for overcoming the noise problem[1]. In the paper[1] the observation confidence was calculated from SNR with sigmoid function. However, estimating SNR needs additive calculation amount and estimated SNR is corrupted in dynamic noisy environments. In this paper we propose estimation methods of the observation confidence based on score-based reliabilities (SBR) of entropy and dispersion measures. Generally SBRs are obtained from speaker models' probabilities. The proposed methods are evaluated with ETRI speaker recognition DB. We compared the performances of the proposed methods with those in [1][8]. The experimental results show that the proposed methods can be successfully applied for the case where SNR is not available.

  • Observation environment of the Bohyunsan Optical Astronomy Observatory(BOAO) has been examined using various statistical data including real observation times versus allocated times and seeing statistics. The data have been collected from the observation logs of the 1.8m telescope in the period 1998 - 2004. New criteria have been set up to calculate a more realistic observation efficiency of the observatory. The new statistical analysis based on the new criteria gives the overall observation efficiency of BOAO as $38.6\%$, that is equivalent to 115.8 observable nights out of 300 allocatable nights. The seeing statistics shows that the mean seeing measured at the focal images is 2".3. The present study of the observation environment of BOAO suggests that differential photometry and spectroscopy should be preferred modes of observation to maximize the productivity of BOAO.

  • Purpose: The purpose of this study was to investigate the improve on brain activity during action observation training for cerebral palsy of diplegia. Design: Randomized controlled trial. Methods: 18 subjects were divide into two groups: action observation training group and a control group. Action observation group practiced repeatedly the action with their motor skill and control group practiced conventional physical therapy. The subjects participated in eighteen 30-min sessions, 3 day a week, for 6week. To confirm the effects on brain activity were evaluated. Results: The results show that the Mu-rhythm was statistically significant increase on the C3 of the action observation training group (p<0.05). Conclusion: The action observation training improves brain activity of a cerebral palsy with diplegia. These results suggest that the action observation training is feasible and beneficial for improving brain activation for the cerebral palsy with diplegia. In the future, I think we need to be actively utilized to the action observation training program in the clinical with the neuromuscular development treatment. And the study on the various the action observation training program that can improve the function of the children with cerebral palsy is thought necessary.
