현대는 첨단과학기술시대라 불리며 그 어느 때보다 경제와 사회적 변화에 따른 창의적 마인드를 가진 인재의 양성과 원천기술의 확보가 중요한 시대라 할 수 있다. 국가적으로도 과학기술이 과학자체뿐만 아니라 국가 경제성장의 원동력인 지식과 기술의 개발에 필수적인 요소이며, 지구와 인류의 현안문제들인 지구온난화, 에너지, 질병, 노령화, 자연재해, 기상 등의 대부분이 과학기술관련 의제임을 인식하여 과학기술에 기반한 창조적 지식국가 건설의 필요성을 역설하고 있다. 이와 같은 과학기술의 기반이 되는 기초과학 중 수학은 과학의 언어로서의 기능뿐만 아니라 기초원천 연구의 핵심이라 할 수 있다. 그러나 우리나라 과학기술인력양성의 핵심이라 할 수 있는 고교와 대학에서는 선택형중심 교육과정 시행이후 고교생의 수학 학습 성취도가 하락하고 자연계과목의 선택 기피가 심화되고, 이에 따라 대학의 이공계열학과 신입생들의 수학 관련과목에 대한 적응이 떨어지고 전공분야에 까지 영향을 끼치고 있다. 따라서 이공 계열학과에서 전공과목에 대한 강의가 영향을 받고 있으며, 이에 따라 수학과 과학의 경쟁력이 저하되고 있음은 물론 과학기술인력의 저변도 축소되고 있음은 잘 알려져 있다. 이와 같은 관점에서 본 연구에서는 대학에서의 수학 관련 과목에 대한 수학(修學)능력저하에 대한 국내의 현황을 분석하고 이와 같은 문제의 핵심이라 할 수 있는 교육과정과 대학입학시험제도에 대하여 고찰하고 효율적인 수학교육 방안을 제시하고자 한다.

Consumer education which changes human value and attitude to attain practice is necessary to solve the problem of environmental, social, and economical sustainability resulted from material and present-oriented consumption and decrease the effect of consumption on the sustainabilities. However, since the present consumer education is biased toward a traditional viewpoint of economical consumption, management of allowances, and rational purchase and its teaching method still stays on memorizing, cramming and one sided lecture, consumer education containing a key value of sustainable development have not been carried out successfully, Specifically, the consumer education in an elementary school treats mainly just on environmental conservation and economical knowledge even though quite much time is arranged in every school year. So, complement of contents such as understanding of relation between natural resources and consumption and the role and responsibility of a consumer is required to emphasis the sustainable development. In this work, a student-oriented educational drama programme for consumer education is developed with respect to an familiar theme of resources such as water, wood, food, and electricity. Educational drama is an efficient teaching method for consumer education of an elementary school student since it makes students experience virtual situation and produce an interest and active participation. How to execute consumer education in an elementary school textbook was analyzed and an educational drama programme was developed and applied, and finally, the programme was qualitatively improved. The paper survey on five teachers practicing the present programme reveals that is it can be affirmatively evaluated since it is familiar to students and leads to their interests and participation. Consequently, it can be confirmed that the present programme can be effective to perform consumer education for sustainable development.

Biometrics identification using multiple modalities has attracted the attention of many researchers as it produces more robust and trustworthy results than single modality biometrics. In this paper, we present a novel multimodal recognition system that trains a deep learning network to automatically learn features after extracting multiple biometric modalities from a single data source, i.e., facial video clips. Utilizing different modalities, i.e., left ear, left profile face, frontal face, right profile face, and right ear, present in the facial video clips, we train supervised denoising auto-encoders to automatically extract robust and non-redundant features. The automatically learned features are then used to train modality specific sparse classifiers to perform the multimodal recognition. Moreover, the proposed technique has proven robust when some of the above modalities were missing during the testing. The proposed system has three main components that are responsible for detection, which consists of modality specific detectors to automatically detect images of different modalities present in facial video clips; feature selection, which uses supervised denoising sparse auto-encoders network to capture discriminative representations that are robust to the illumination and pose variations; and classification, which consists of a set of modality specific sparse representation classifiers for unimodal recognition, followed by score level fusion of the recognition results of the available modalities. Experiments conducted on the constrained facial video dataset (WVU) and the unconstrained facial video dataset (HONDA/UCSD), resulted in a 99.17% and 97.14% Rank-1 recognition rates, respectively. The multimodal recognition accuracy demonstrates the superiority and robustness of the proposed approach irrespective of the illumination, non-planar movement, and pose variations present in the video clips even in the situation of missing modalities.

The present paper shows the possible development of particle swarm optimization (PSO) based fuzzy-neural networks (FNN) which can be employed as an important building block in real life robot systems, controlled by voice-based commands. The PSO is employed to train the FNNs which can accurately output the crisp control signals for the robot systems, based on fuzzy linguistic spoken language commands, issued by an user. The FNN is also trained to capture the user spoken directive in the context of the present performance of the robot system. Hidden Markov Model (HMM) based automatic speech recognizers are developed, as part of the entire system, so that the system can identify important user directives from the running utterances. The system is successfully employed in a real life situation for motion control of a redundant manipulator.

Objective: The present study examined how childcare teachers at home daycare centers perceive their rights as teachers and what kind of rights situations pertain to them at their respective daycare centers. Methods: Adopting a qualitative research method approach, this study conducted focus group interviews to collect empirical data. The participants were childcare teachers and directors at home daycare centers, which were shown to have relatively poor work environments compared to other types of daycare centers Results: The findings revealed that the participants at home daycare centers perceived their rights as childcare teachers to be extremely vulnerable. It was shown that their rights could not be protected in various frameworks involving mutual relations between teachers and directors, the Infant Care Act and childcare policy, and social perceptions that fail to recognize them as professionals. Conclusion: The fingdings from the present study contribute to our understanding of the rights situation faced by childcare teachers at home daycare centers and to the social discourse on finding ways to realize the teachers' full rights as childcare professionals.

High sodium intake in many countries has become the leading cause of chronic diseases. This situation requires correct dietary behavior to ensure proper sodium intake in the younger population. The purpose of the present study was to assess eating behavior regarding sodium intake and identify its correlation with common dietary attitudes in children. This cross-sectional study was conducted by surveying 588 elementary school children in Korea. Sodium-related dietary behavior and common eating attitudes were examined through questionnaires, and analyses were conducted by comparing the results between boys and girls. The most undesirable sodium-related dietary behavior in subjects was they 'eat kimchi with every meal' followed by the 'tendency to eat hot and spicy food'. Girls had better dietary behavior regarding sodium intake than boys (P<0.05). However, the common eating attitude between boys and girls was not significantly different. For all subjects, sodium-related dietary behavior and eating attitude showed a significant positive correlation (P=0.0032). The present study shows that a common eating attitude is better when the sodium-related dietary behavior is more desirable in children.

본 연구에서는 이런 점들을 고려, 난류유동장 내의 실제 입자운동을 좀더 사 실에 가깝도록 해석할 수 있는 모델을 제시하여 아직 실험에 의존하고 있는 관계분야 에 그 이론적 응용범위를 넓히는데 그 목적을 두었따. 본 연구의 목적상 입자가 존 재하는 난류장의 통계적 특성은 이미 알고 있는 것으로 가장하였으며 유체 내의 입자 농도가 충분히 낮고 입자의 크기가 충분히 작아서 입자가 유동장에 미치는 영향은 무 시할 수 있다고 간주하였다.

This study, from conditions connected with water in Feng-Shui theory, is to find out their influence of the location and spatial composition of the studied villages, Hawei and Yangdong, and then to offer the result as basic data for the study of the traditional village in the future. The study method is to analyze topography by the map and present state of villages studied, to interprete them on the base of location, spatial composition, and chi, and then to analyze the relevancy of Feng-Shui theory of them. The result of the study are to be following: Houses of Hawei village are situated on the inside of a winding stream of waterway, while those of Yang dong village are located on the outside of a winding stream of waterway. In case of Hawei village, showed the close interrelation between the distribution of present houses and running speed of waterway by positin. Judging from the location, orientation and surroundings of mountains and waterway, topographical composition of Hawei village is Duk su guk, but that of Yang dong village is Juang feng guk. Comparing with Yang dong and Hawei in location and spatial composition, the conditions of waterway as being locational factor, for example, the geomancy of situation, orientation, and phisical phenomena(lenth, width, and depth of waterway in front of village) of waterway, are more importantly considered in Hawei village being situated on even land than in Yang dong located at the foot of the mountain.

This paper aims to present a prospective trend to establish a proper CALS conception and an efficient CALS environment in Korea.. It is crucial at this point for Korea to develop a comprehensive CALS conception which considers our present economic and social situation, national security, and our national emotion. Korean CALS has been developed and led mainly by the government and private industry. It is now necessary to improve CALS conception in Korea by making CALS standard more interchangeable among international as well as domestic business fields through EDI and the automation of the industries along with the government. In this regard, this paper proposes three potential methods to accomplish this goal and discuss each of them in detail. First, we suggest to establish a proper CALS introduction policy on the government level. We propose an introduction policy with three phases such as introduction, spreading and target which will cover through the year 1996 to 2007. Second. we suggest to establish a proper CALS standardization policy by improving the acquisition of digital data and process, and modernizing infrastructure. Third, we suggest that the government should amend and enforce the necessary laws and acts for more efficient CALS implementation in Korea. Government should arrange for these acts to be applied not optionally but obligatorily to Korean enterprises so that they survive the harsh and competitive world market in the upcoming 21th century.
