Currently, the robot is widely utilized in various educational settings such as after-school classes, and special classes for gifted students. The robot is widely recognized as a useful tool for helping students solve problems. The core activities of programming learning with robot need to provide various problem contexts to the students and guide students' problem solving process. Students gain cognitive and affective benefits when they solve problems with robots. This paper describes the impact of programming learning using robot based on schoolwide enrichment model on elementary school students' creative potential. As a result, the students of experimental group than the students of the control group improved creative personality and ideational behavior, and the gifted students of experimental group than the gifted students of control group improved ideational behavior.

In order to investigate the geochemical characteristics of surface sediments in streams of upper Yeongsan River drainage system, sediment samples from the main stream of Yeongsan river, Hwangryong river, Gwangju and Jiseok streams were collected and analyzed for grain size and metal and organic carbon contents. The metal contents in the sediments are mainly dependent on organic matter contents in the domestic sewage, grain size of the sediments and geology around the streams. Enrichment factor (EF) and index of geoaccumulation (Igeo) representing the degree of metal contamination in the sediments are relatively low in the main stream of Yeongsan river main stream, Hwangryong river and Jiseok stream. However, those of Gwangju stream show the EF maximum values of P=8.30, Cu=5.55, Zn=14.29 and Pb=7.45 and the Igeo maximum values of P=3.58, Cu=4.43, Zn=3.22 and Pb=1.59.

With the development of information and communication technology, various data have appeared and are being distributed. The use of various data has contributed to the enrichment and convenience of our lives. Data in the public areas is also growing in volume and being actively used. Public data in the field of education are also used in various ways. As the distribution and use of public data has increased, advantages and disadvantages have started to emerge. Among the various disadvantages, the privacy problem is a representative one. In this study, we deal with the privacy issues of public data in education. First, we introduce the privacy issues of public data in the education field and suggest various solutions. The various solutions include the expansion of privacy education opportunities, the need for a new privacy protection model, the provision of a training opportunity for privacy protection for teachers and administrators, and the development of a real-time privacy infringement diagnosis tool.

The evolution of the Galaxy is examined by the halo-disk model, using the time-dependent bimodal IMF and contraints such as cumulative metallicity distribution, differential metallicity distribution and PDMF of main sequence stars. The time scale of the Galactic halo formation is about 3Gyr during which the most of halo stars and metal abundance are formed and ${\sim}95%$ of the initial halo mass falls to the disk. The G-dwarf problem could be explained by the time-dependent bimodal IMF which is suppressed for low mass stars at the early phase (t < 1Gyr) of the disk evolution. However, the importance of this problem is much weakened by the Pagel's differential metallicity distribution which leads to less initial metal enrichment and many long-lived metal-poor stars with Z < $1/3Z_{\odot}$ The observational distribution of abundance ratios of C, N, O elements with respect to [Fe/H] could be reproduced by the halo-disk model, including the contribution of iron product by SNIs of intermediate mass stars. The initial enrichment of elements in the disk could be explained by the halo-disk model, resulting in the slight decrease and then the increase in the slopes of the [N/Fe]- and [C/Fe]-distributions with increasing [Fe/H] in the range of [Fe/H] < -1.

Based on the conceptual framework of Double ABCX model of family stress and adaptation this study developed the enrichment program for the relationship of young daughters-in-law with their mothers-in-law. Results of empirical research concerning the relationship between them also provided for the basis of designing this program. Consisting of 6 sessions this education program was delivered to 20 young daughters-in-law in a rural area of Kyunggi-do province. The effectiveness of the program was evaluated through one-group posttest design and follow-up interview. Overall most participants in the program reported that the relationship with their mothers-in-law was enhanced in terms of understanding mothers-in-laws psychology and roles of improving communication and problem-solving skills self-control and of blaming.

Subjects were two teachers each with higher or with lower play teaching efficacy, and the 111 four and five-year-old children they taught. Using naturalistic observation, children's constructive play was videotaped and transcribed for 60 minutes on ten consecutive days in each classroom. Play was analyzed by level of constructive play, continuous length of play, variety of materials, enrichment of activities, and coherence of content. Constructive play of children whose teachers had higher efficacy in teaching play showed longer continuous play, used a higher variety of materials, and their play had more creative integrity. Five-year-olds exhibited longer continuous play, used a larger variety of play materials, more enrichment of play activity, and more coherence in play contents than four-year-olds.

The purpose of this study was to examine the concept of r-learning based on existing studies of r-learning. It also aimed to analyze r-learning environments in an effort to determine prerequisites for the successful entrenchment of r-learning in material(technology and infrastructure), human(young children and teacher) and institutional(law and policy) aspects. This study intended to suggest some of the right directions for the revitalization of r-learning. In conclusion, the position of r-learning and its interrelationship with related systems in the ecosystem of early childhood education should accurately be grasped to accelerate the integration of r-learning into kindergarten education to maximize the effects of the convergence of the two. Intensive efforts should be made from diverse angles to expedite the spread and enrichment of r-learning.

The purpose of this study is to conduct base line research, which is based on requestion of international married immigrant women, for developing social adaptation and family enrichment program for those population who reside in Korea. The survey questionnaire was distributed to 142 international married immigrant women who reside in Seoul to research program participate satisfaction and requestion. Analyze the study results, frequency, percentage, t-test, ANOVA and Duncan-post test were utilized. As a result, overall satisfaction toward program that offered by organization was highly ranked. Visiting service showed high score of satisfaction but mentor service that strongly possess sacrifice showed lower score of satisfaction. Vocational and job-related skill improvement education presented less satisfied degree of satisfaction but cooking class, computer class, training education for native-speaking instructor present high level of satisfaction. Second, the requisition of target population, who did not participate program, presented lower than the satisfaction, still present high demand of variety area of program. Among them, assist child nurturing and vocational and job- related skill improvement education showed high demand. It enable to predict that they are eager to get support toward parent role and self-realization. Third, when the difference were analyzed to compare the subjective judgement toward life adaptation in Korea and the satisfaction for program user and the requisition of non-user, the meaningful differences were founded; especially, individuals who possess confident degree of computer skills and Korean(reading, speaking, and listening) showed higher degree of satisfaction to vocation and job-skill related improvement education. This study has a practical implication, which is based on the study results, on developing a program to support international married immigrant women and multicultural families to satisfactory settlement in Korea life and to maintain healthy families.
