In this paper, we present a CNN-based gesture recognition approach which reduces the memory burden of input data. Most of the neural network-based gesture recognition methods have used a sequence of frame images as input data, which cause a memory burden problem. We use a motion history image in order to define a meaningful gesture. The motion history image is a grayscale image into which the temporal motion information is collapsed by synthesizing silhouette images of a user during the period of one meaningful gesture. In this paper, we first summarize the previous traditional approaches and neural network-based approaches for gesture recognition. Then we explain the data preprocessing procedure for making the motion history image and the neural network architecture with three convolution layers for recognizing the meaningful gestures. In the experiments, we trained five types of gestures, namely those for charging power, shooting left, shooting right, kicking left, and kicking right. The accuracy of gesture recognition was measured by adjusting the number of filters in each layer in the proposed network. We use a grayscale image with 240 × 320 resolution which defines one meaningful gesture and achieved a gesture recognition accuracy of 98.24%.

This study proposes a Word Sense Disambiguation (WSD) algorithm, based on concept learning with special emphasis on statistically meaningful lowest frequency words. Previous works on WSD typically make use of frequency of collocation and its probability. Such probability based WSD approaches tend to ignore the lowest frequency words which could be meaningful in the context. In this paper, we show an algorithm to extract and make use of the meaningful lowest frequency words in WSD. Learning method is adopted from the Find-Specific algorithm of Mitchell (1997), according to which the search proceeds from the specific predefined hypothetical spaces to the general ones. In our model, this algorithm is used to find contexts with the most specific classifiers and then moves to the more general ones. We build up small seed data and apply those data to the relatively large test data. Following the algorithm in Yarowsky (1995), the classified test data are exhaustively included in the seed data, thus expanding the seed data. However, this might result in lots of noise in the seed data. Thus we introduce the 'maximum a posterior hypothesis' based on the Bayes' assumption to validate the noise status of the new seed data. We use the Naive Bayes Classifier and prove that the application of Find-Specific algorithm enhances the correctness of WSD.

This study is aimed to investigate ethics cognition to information of youths who are main users of computers, but yet not built up the own ethics and the sense of value, as ethical problems are raised in information-oriented society. The research was focused on youths ethics cognition to information according to contact of multimedia pornography, surreptitious use of others and abusion of indecent languages in chatting. The survey was conducted to 520 students from middle and high schools in Jeju region and analyzed Probit Regression. The major results of this study are as follows; First, most of youths possess own-computers, and use Internet. Second, looking into experiencing or not according to sub-spheres of ethics cognition to information, the experience of contacting multimedia pornography was few. but the primary place of using it was a house. Most of youths approach multimedia pornography in awareness of a ban on youths' contact. The experience of surreptitious use of others was less than other spheres, and mainly only once. The number of youths who have an experience of abusing indecent languages was less than that of youths who don't have, but the frequency of was high when the youths have an experience. Third, the experience or no experience on each sub-sphere has a significant difference on personal-relative variables such as gender, age, education levels, number of siblings, academic records, personal expenses, relationship with friends. The experience or no experience on each sub-sphere has a meaningful influence upon family-relative variables such as father's education levels, Job, mother's age, education levels, employment, family type, monthly household expense. The experience or no experience on each sub-sphere has a meaningful influence upon PC-relative variables such as deviation experience in PC rooms, the experience of request for age confirmation(I.D. card), average use hour of PC rooms. The experience or no experience on each sub-sphere has a more meaningful influence on personal-relative variables and PC-relative variables than family-relative variables.

Methods: Make use of SAS 8.0 of windows and descriptive statistics analysis on investigate Dental Technology 570 students in Daegu. And also it analyzes difference of ispectable t-test and ANOVA. Results: According to a gender, a job experience, where they are come from, there is a meaningful difference of an information and an entrance motive for choosing a major (<.05). The time of choosing the major are different meaningfully (<.001). An awareness about the method of a career achievement is a meaningful difference between men and women(<.05). As getting old, the method of a career achievement is higher and there are meaningful differences according to a grade, job experience and a entrance screening(<.01). In accordance with a gender, a grade, entrance screening, there are meaningful differences of a degree for obtaining the career information activities(<.01). In accordance with an age, when they choose a major, there is a difference(<.001). In accordance with a gender and a age, there are meaningful differences of a career plan(<.001). The age difference is slight. In accordance with a gender and a age, there are meaningful differences how to effort for the career(<.001), and also according to an entrance screening, an entrance motive(<.05). These mean that the first priority for choosing the career and going into the world is a school record. There are meaningful differences of people that the student choose for consulting the career(<.01). According to the job experience there are meaningful differences(<.001). Conclusion: By investigating and analysing the student's career plan, we need to seek how students choose their career reasonably and desirably. And also we need to teach a career education systematically.

Fairy-tales give students opportunities to build connections between a problem-solving situation and mathematics as well as to communicate solutions through writing, symbols, and diagrams. Therefore, the purpose of this paper is to introduce how to use fairy-tales in elementary mathematics classroom in order to develope student's mathematical concepts and process in terms of the following areas: ⑴ reconstructing literature ⑵ understanding concepts ⑶ problem posing activity. To be useful, mathematics should be taught in contexts that are meaningful and relevant to learners. Therefore using fairy-tales as a vehicle to teach mathematics gives students a chance to develope mathematics understanding in a natural, meaningful way, and to enhance problem posing and problem solving ability. Further, future study will continue to foster how fairy-tales literatures will enhance children's mathematics knowledge and influence on their mathematics performance.

The objective of most image proccessing applications is to extract meaningful information from one or more pictures. It is accomplished efficiently using neural networks, which is used in image classification and image recognition. In neural networks, background and meaningful information are processed with same weight in input layer. In this paper, we propose the image classification method using neural networks, especially EBP(Error Back Propagation). Preprocessing is needed. In preprocessing, background is compressed and meaningful information is emphasized. We use the quadtree approach, which is a hierarchical data structure based on a regular decomposition of space.

The purpose of this study was to identify differences in cognitive function according to the presence or absence of apraxia and the tasks most relevant to the cognitive function among the various types of tasks in the apraxia test. The subjects were 42 community residents who participated in a cognitive rehabilitation program related to dementia in a Chungbuk area. MMSE-K and BCoS(Birmingham Cognitive Screen) apraxia test were administered to all subjects. The apraxia test includes three types of tasks, gesture production tasks that make meaningful movements according to verbal instructions, gesture recognition tasks that display behavior after make sense of meanings, and meaningless imitation task. Apraxia group(n=30, MMSE-K mean score: 25) showed lower cognitive function than group without apraxia(n=12, MMSE-K mean score: 28). All tasks in the apraxia test showed a significant correlation with cognitive function, but the meaningless imitation task had a negligible correlation. The apraxia test is a good way to assess cognitive function, and it may be more effective to use meaningful behavior to replace cognitive testing.
