This paper describes design and implementation of a general purpose cyber educational system. In this system, there are different types of menus and services according to such user's rights as system operators, professors, assistant instructors, students. In order to keep in close contact between students and professors, provided are various services such as the official announcement, transcripts of lecture, bulletin board, Q/A corner, report box, archive of study materials, electronic mail box, memorandum including checking of one's attendance and school record. For the purpose of activating small group studies and discussion about given subject, it can organize into groups automatically and provide with debating rooms. The system is implemented by separating with both HTML design and programming part by templete concept. Overload of iterative server is solved by adjusting the numbers of DB servers of each service.

This study purposed to examine the effects of the Feuerstein's cognitive mediated learning for gifted children on attention control and attention shift. For the study, 40 gifted students were chosen from the 3rd graders in elementary schools and divided into test and control groups using K-WISC-III and Torrance Tests of Creative Thinking. The mediated learning program that is targeted to improve the executive functions of gifted children has used the tools of Organization of Dots, Analytic Perception and Comparisons among Feuerstein's Instrumental Enrichment(FIE). According to the results of this study, a significant improvement has been observed in selective attention, self-control, sustained attention, and attention shift through cognitive mediated learning. Therefore, it has been proven that the cognitive mediated learning is effective in reducing gifted children's problematic behaviors that are caused by a lack of attention control and attention shift and improving their cognitive functions and potentials.

This study aims to examine the mediating effect of parental monitoring and child's self-esteem on the relationship between parental time and child's life satisfaction in single mother families. For this purpose, MOGEF (Ministry of Gender Equality and Family)'s 'Research data of adolescents in 2015' was used and 117 single mothers and their children aged 9 to 18 were selected for the analysis. Structural Equation model analysis reveals that adolescent's self-esteem has a mediating effect on the relationship between parental time and adolescent's life satisfaction, though parental time and parental monitoring have no significant effect on adolescent's life satisfaction. With these results, policy suggestions to support single mothers' parental time were proposed.

The purpose of this study is to develop a smart device-based Language Rehabilitation Program (LRP) to improve communication ability for the patients with language disability. The content of the LRP includes a variety of semantic categories and grammatical elements and consists of 17 semantic categories, 29 tasks and 3780 items to improve comprehension/production ability at word level, semantic category level, sentence level and discourse level. We developed LRP as a Windows-base management program and an Android-base language rehabilitation application. LRP was developed into an application for smart devices, providing real-time delivery of training contents, measurement and database of training task results, and patient progress and monitoring. A follow-up study will be conducted on the verification of the language rehabilitation effect using LRP by patients with language disability.

This study aims to investigate the effects of literary texts as a teaching tool to enhance college students' English communicative competence both in linguistic aspects and affective ones. The control group used only the course book as study material, whereas the target group read four short stories along with it and engaged in a series of follow-up tasks. To measure their English competence, the researcher had both groups take a pre-test and a post-test, compared the results, and analyzed the data using SPSS. The study indicates that though the target students' post-test scores increased, the result failed in reaching a significant level. Nevertheless, reading and discussing literature facilitated the target students' affective aspects of communication. This article points out some other limitations of utilizing literary texts in language teaching and suggests the need for further research to deal with the issues.

In online meetings and classes using webcams, the chromakey technique is a very necessary part to produce content. We proposed a technology that enables background synthesis without using a cloth for chromakey. The proposed method consists of three steps: an HSI image conversion step, a step of detecting a region changed from a background, and a step of replacing the background region with a chromakey and applying it. In the input video, the block average image of each frame is calculated, and the difference between the block average image of the background image and the block average image of the input image is used to detect the change area. The developed chromakey effect technology uses a technique of acquiring a background image without an object from a single camera and extracting only an object by distinguishing the moving object and the background. The proposed method is not only capable of processing even if the background has a variety of colors, but also has the seamless processing of the boundary lines of objects.

The purpose of this study is to develop an evaluation model to measure the core competences of actual play workers by exploring what competences are necessary for them to provide quality play. Based on literature review, we selected five core competences : knowledge of play, program development, understanding play culture, creativity, and information sharing & applying. In order to achieve the research purpose end, a two-round Delphi survey was conducted on 10 play and education experts. The findings drew scholarly consensus on the competences of play workers to have and proposed basic data by developing competences evaluation model to measure them. Each of the key competences has three sub-conpetences, each of which included two behavior elements. Furthermore, this study presented future research directions so that play can be voluntarily planned and supported in a social and cultural context.

The purpose of this study is to provide academic and practical implications through empirical analysis on the moderating role of SHRM that is relatively lacking in the relationship between CLMRC and performance. In order to achieve the research purpose, data were collected from 123 CEOs of Korean companies. The reliability and validity of the collected data were examined and the hypothesis was verified by hierarchical regression analysis. The results of this study show that CLMRC has a meaningful positive(+) effect on both net profit and sales per person, and SHRM has shown to have a moderating effects between CLMRC and sales per person, CLMRC and net profit. Through this analyzes, CLMRC can enhance the management performance, and in this process, the more strategic the human resource management(HRM) is, the more the impact on the management performance is strengthened. Implications for CLMRC and SHRM, limitations of the study and suggestions for future researches are discussed.

Modern society has a tendency to raise fewer children. As a result, parents became more interested in their children's creative ways of thinking and began to look for new ways of teaching. The child care support center expects a positive effect by lending various toys and books to improve the physical, emotional and social characteristics of children and to help reduce household burden on parents. In this paper, we design and implement a rental return system to effectively utilize a toy library operated by the child care support center. The proposed system makes it easy for any user to search for items in any branch operated by the Child Care Support Center and to manage loan return records. The administrator can manage data such as loans, returns, and past due from the rental return processing system, and effectively operate the child care support center through statistics of data generated. Children are expected to be given a variety of entertainment cultures and cultural benefits to their families to ease the burden of parenting.
