In this study, the characteristics of the reading materials in elementary school science textbooks developed under the 2009 revised National Science Curriculum were investigated. The criteria for classifying the reading materials were the types of topic, purpose, students' activity, and presentation. The visual images in the reading materials were also analyzed from the viewpoint of type, role, caption type, and proximity type. The results indicated that the number of the reading materials in the 2009 revised science textbooks decreased compared to that of the 2007 revised science textbooks. It was also found that the frequencies of the reading materials expanding concepts of the text and/or requiring corresponding students' inquiry increased. More visual images were used in the reading materials of the 2009 revised science textbooks. However, several limitations were still found to exist; most visual images were illustration and/or picture; many visual images were presented without a caption; there was a problem in the proximity of visual image to text.

This study analyzes the comsumer complaints that are listed on bulletin board (or Q & A page) of mobile game sites in order to search for comsumer problems in the contents of mobile games. This analysis includes 3,664 cases of complaints on 17 mobile game sites. The finding indicates that they can be categorized into 10 types of complaints: game errors, how to play, game quality, game capacity, fee inquiry, excessive fees, lack of information, refund, unfulfilment of promises, game support. The problems with the game itself account for 54.8% of total complaints, and unsatisfaction from game fees and others take up 25.5% and 19.7% respectively. Therefore, we suggest that first, the quality of mobile games and consumer education be improved, second, information about game fees be provided to consumers more sufficiently in a proper manner, and lastly pertinent regulations on consumer damages compensation and adhesion contracts be established.

정보검색에서 질의확장은 가장 널리 알려진 기술로서 사용자가 입력한 질의에 외부적인 지식을 추가해서 조건에 맞게 질의를 확장시켜 검색도구의 능력을 향상시키는데 많이 사용되어 왔다. 하지만, 질의에 사용되는 단어의 애매모호함은 검색도구가 성능을 낮추기 때문에 이러한 문제는 여전히 풀어야 할 과제로 남아있다. 본 논문에서는 단어의 의미를 나타낼 수 있는 도메인을 사용해서 이러한 문제를 해결하는 방법을 제시한다. 특히 토픽 모델을 이용한 도메인 중심 모델을 사용해서 질의를 확장하는 기술을 제안한다. 실험은 기존 모델들과 비교로 이루어졌고, 그 결과 제시된 방법은 높은 성능을 보이는 것으로 나타났다.

This study was aimed at developing eco-STEAM educational programs based on smart learning, implementing the programs to verify their educational effectiveness, and exploring the possibilities for eco-education. The subjects of Science, Mathematics, Practical Arts, Arts, and Physical Education were analyzed to extract STEAM elements for the 5th and 6th grades at elementary school, and then 16 lessen plans were developed under 8 thematic strands. The programs were applied to classes of 5th and 6th graders, and then tested to see the effectiveness in terms of emotional experience, convergence, creative design and satisfaction. The average scores for post-test were statistically higher than those of pre-test(p<.001), showing positive effectiveness of the eco-STEAM programs developed. This study put out the following conclusions. First, the students got emotional experiences through inquiry and observation. Second, the programs helped students to learn about the environment in their contexts and provided a base for interdisciplinary approach. Third, the students in this study could have opportunities for improving their problem-solving abilities by using the creative design. Forth, the students' interests in the ecological topics were increased throughout regular curricula.

The purpose of this study is to develop a student-led instructional strategy that is central to the teaching-learning process and to investigate its effects. For this study, we analyzed the learner-centered learning types (discovery learning, problem-based learning, inquiry learning) and extracted elements applicable to newly developed teaching-learning. Based on this, a student-led class strategy was established using pre-learning, teacher collaboration, small group composition, and limited open data and product presentation, and then science classes were conducted. As a result of the post-tests of the five science core competencies of the experimental group using the student-led instructional strategy and the comparative group conducting lecture-based classes, the experimental group showed higher scores than the comparative group in the scientific thinking, scientific communication, and scientific attitudes (p<.05). Based on these results, it was confirmed that the student-led class, in which the student self-adjusts the entire process of designing, exploring, and presenting learning, can help the student's scientific ability. In addition, I would like to discuss the implications of teachers' teaching-learning composition.

Purpose: This study was to identify and to search the related disposition of the pattern of anxiety and coping in mothers of children with nephrotic syndrome through the use of Q-methodology. Method: 34 Q-samples were finally selected in the concept of anxiety and coping. A P-sample of 35 was selected the mothers of children with nephortic syndrome. The result of the Q-sorting was coded and analyzed using QUANL PC program. Result: There were 3 types of special opinion. The first type is called ' Pursuit of hope type.' Members of this type were cope with the anxiety by spiritual behavior like a pray, positive thinking. The second type is called 'Worry about reality type.' Members of this type were to be filled with apprehension like an indigestion, insomnia. The third type is called ' Solving problem type.' Members of this type were cope with the humanity effort by conversation. Conclusion: The mothers of children with nephrotic syndrome were used various coping patterns to cope with the anxiety conditions that their child were result from admission to hospital and treatment of the disease. Therefore, nursing assessment and nursing intervention skills have to develop in consideration of the subjectivity of coping about anxiety in each individual.

The purpose of this study was to investigate the characteristics of reasoning in which $3^{rd}$ grade elementary school students form ideas, design experiments, and interpret the results to solve problems in small group argumentation. For this purpose, 12 3rd-grade students' small group argumentations including experiments were observed. The researchers analyzed students' pre- and post-open questionnaires, field notes, and video recordings of small group argumentation. The results of the research are as follows. First, in the initial opinion formation process, a hasty unification of opinions and a transformation of inquiry problem occurred. In the design and execution of experiments, verification experiments and unplanned and arbitrary experiments were performed. They also selectively noticed or accepted claims, evidence, interpretation, and criticism. They could distinguish between the condition and the cause, but they were confused by using inaccurate terms and tended to keep the initial opinions when interpreting the results and drawing conclusions.

This study aims to reflect the origin and the meaning of open education and to derive pedagogical principles for open mathematics education. Open education originates from Socrates who was the founder of discovery learning and has been developed by Locke, Rousseau, Froebel, Montessori, Dewey, Piaget, and so on. Thus open education is based on Humanism and Piaget's psychology. The aim of open education consists in developing potentials of children. The characteristics of open education can be summarized as follows: open curriculum, individualized instruction, diverse group organization and various instruction models, rich educational environment, and cooperative interaction based on open human relations. After considering the aims and the characteristics of open education, this study tries to suggest the aims and the directions for open mathematics education according to the philosophy of open education. The aim of open mathematics education is to develop mathematical potentials of children and to foster their mathematical appreciative view. In order to realize the aim, this study suggests five pedagogical principles. Firstly, the mathematical knowledge of children should be integrated by structurizing. Secondly, exploration activities for all kinds of real and concrete situations should be starting points of mathematics learning for the children. Thirdly, open-ended problem approach can facilitate children's diverse ways of thinking. Fourthly, the mathematics educators should emphasize the social interaction through small-group cooperation. Finally, rich educational environment should be provided by offering concrete and diverse material. In order to make open mathematics education effective, some considerations are required in terms of open mathematics curriculum, integrated construction of textbooks, autonomy of teachers and inquiry into children's mathematical capability.
