The purpose of this study is to discuss information literacy in mathematics education by comparatively analyzing mathematics education experts' perception of information processing and information literacy in mathematics education. We collected mathematics education experts' opinions using the modified Delphi method and focus group interviews, then analyzed their responses with an analytic framework through a constant comparative method. Even though we used different methods, we could compare their perceptions under the common themes. The findings are in three-folds. First, most experts focused only on the use of technological tools or statistics as a way of developing information literacy. In addition, even though mathematics education experts recognize the need for information literacy in mathematics education, their definition and meaning of information literacy somehow varied. Secondly, teachers as practitioners emphasized social competency which could be developed through information literacy. Thirdly, they asked for concrete and systematic plans for school practice in order to well develop information literacy in schools. Even though there were some differences in their perception of information literacy in mathematics education in terms of their prior experiences and background, it is very meaningful that there were commonalities among their perceptions which would allow us to find the ways of developing information literacy in mathematics education.

The purpose of this study was to develop e-learning contents and to examine how ICT-powered instruction using the developed e-learning contents affects the science achievements of students and how the students respond to that. After an experiment in the 7th class of the weather condition unit in high school earth science, e-learning contents were prepared by using the videotaped material and flash animation to teach key learning points. The selected two different classes, experimental and control groups, shows almost the same final scores in the first semester. The experimental group received ICT-powered instruction with the contents developed in the study, and the control group received a typical expository lesson. And then the achievement test was done to these two groups, separately. The major findings of the study were as follows: As for the effects of ICT-powered instruction on the academic achievement, the average scores of the experimental group is higher than that of the control group, but the difference is insignificant. When each group was subdivided into the upper and lower groups, the upper group got higher average scores and the difference was significant. But there was no significant disparity between the lower groups. Therefore, the ICT-powered instruction using the e-learning contents gives a good effect on the students whose levels are higher than the average. In the questionaike about the ICT instruction, they generally had a positive opinion about its impact on learning interest and class participation and its learning effects.

This study intended to activate public education, researched and analyzed real conditions of preschool education to know desirable directions of public education and help parents recognize public education. The final purpose is to offer basic materials to reestablish preschool education in the public education system. First, parents' recognition concerning preschool education in the public education system was much different from that of teachers. As for definitions of preschool education as a public education, parents understood that it means 'the nation and self-governing bodies manage aid both the public and private kindergartens', and teachers recognized that it means that 'the nation and self-governing bodies not only found operate public kindergartens but also aid manage educational funds of private kindergartens. Second, the examination of educational environments of kindergartens told that teachers and parents thought that opportunity to enter the kindergarten is not equal for all children in our country, and quality of kindergarten teachers is satisfactory. Also, they thought that curriculums of preschool educational organs have been set well according to children's developmental stages, education quality is different according to preschool education organs' foundation-types. They recognized that facilities and apparatus of preschools are satisfactory, security and neatness of preschools are satisfactory, too. Third, the examination of developmental directions of preschool education as a public education proved following facts; as for foundation-types of kindergartens in the future when promoting preschool education as a public education, parents answered financial support and supervision by the government, teachers answered aid and management of operational fees as well as support for teacher personnel expenses.

요즘은 모든 작업이 컴퓨터 환경에서 이루어지고 있다해도 과언이 아니다. TV 연속극을 보면 이전과는 크게 다른 점이 느껴진다. 사무실뿐만 아니라 가정에도 책상 위에는 반드시 컴퓨터가 놓여 있다. 얼마 전만 해도 컴퓨터 옆에는 모니터만이 있었는데, 요즘은 프린터도 필수품이 되고 있다. 모니터 화면을 보면서 디자인이나 편집작업을 자유롭게 할 수 있고 마음에 드는 결과물을 바로 프린터로 출력할 수 있어 매우 편리하다. 그러나 이러한 작업에 있어서는 모니터 화면에 나타난 색과 프린트된 색이 달라 난감하던 경험은 누구에게나 있을 것이다. 이러한 차이는 왜 생기는 것일까? 이를 극복할 방법은 없는 것일까? 먼저 색이 만들어지는 원리에 대해 살펴보자.

그 동안 방산물자 수출 활성화에 관한 연구는 방산관련 전문가들에 의해 많이 연구되어 있지만 이에 따른 개선의 노력은 아직까지 미흡한 것으로 생각된다. 이는 방위산업 및 방산물자 수출에 관한 정부와 관련 방산업체간의 인식의 차이 등 여러 가지 원인들이 복합적으로 작용한 것으로 생각된다. 따라서 앞으로 정부는 방산업체를 안보의 동반자로서 자주 만나서 방산물자 수출에 대한 의견이 상호교환 되어야 하며, 방산업체는 단순한 이익 추구보다는 국가안보에 기여한다는 사명감과 자긍심을 가지고 경쟁력 있는 선진국형 방위산업 기반을 구축할 수 있도록 상호협력과 노력을 다해야 할 것이다.

The purpose of this research is to investigate adult's perception of elderly parents care and differences of related variables between family structures. There were 1,258 participants(age 45; male=601, female=657; 1,111=nuclear, 147=extended). The measures yielded Cronbach α=.67~.95, inter-judger reliability= 95.1%, Kappa=.95. The results showed that, first, there were no significant differences between two family structures in terms of SES excepting academic career. Second, there were significant differences between two family structures in family relation, psychological characteristics. That is, adults in the extended family, versus those in the nuclear family, provide greater emotional support to children, sacrificed more towards children, and have greater expectations for children supporting them when they retire. Also, adults in the extended family displayed greater self-efficacy and happiness. Third, there were significant differences between two family structures in caring for elderly parents. Adults in the extended family apportioned a greater parent's allowance, and more number of meals with parents, and spent more time talking with parents, and displayed greater degree of filial piety and more caring behavior towards parents. Fourth, as for the perception of caring for elderly parents according to family structure, when adults were asked about "the best way to care for parents", the most frequent response was providing a peace-of-mind for parents. As for "the most difficult aspect of caring for parents", differences in opinions followed by financial difficulty were the most. As for "the best aspects of caring for parents", the most frequent responses were good for children's upbringing and family harmony. Based on the results, suggestions for further research have been discussed.

This paper aims to provide reference model for directions and objectives of Software(SW) gifted education. In order to achieve the goals introduced above, we conducted the research in the following steps. First, we selected the concept of ICT-based creative talented person as a base model to establish the concept of SW gifted person. The selected base model composed three core competencies which were 'knowledge and technology competencies', 'synthesizing and creativity competencies', and 'personality competencies'. Second, we developed survey tools, like questionnaires, to investigate participant's recognition of SW gifted person. The survey tools composed three components 'computational thinking', 'entrepreneurship', and 'social responsibility'. Each of the components composed seven elements. Third, after selecting the opinion poll participants as an elementary school teacher, we surveyed opinion polling. By selecting an elementary school teacher as the opinion poll participants, we wanted to identify theirs ' opinions which are thought to be the starting point for gifted education. To survey we developed on-line survey system by using Google functions. Fourth, we analyzed the collected opinion data. To identify we summarized and synthesized participant's opinions that average values and agreement level by using frequency analysis. Also, in order to compare opinions that average values and agreement level based on whether or not participant's various experiences and competencies we computed t-value, F-value, and ${\chi}^2$ verification.

This study examined the effects of parents' appearance-related parenting styles on children's adolescence and self-esteem by examining university students' appearance satisfaction. The results generated 3 different appearance-related parenting styles for fathers: indifference type (45.5%), conservative regulation type (32.0%) and appearance-pursuing type (22.5%), and three for mothers: opinion-respecting type (39.5%), conservative regulation type (32.6%) and appearance-pursuing type (27.9%). In addition, when the influence of parenting styles were compared based on children's self-esteem and their appearance satisfaction, male students' appearance satisfaction was affected more by their self-esteem than by parents' parenting styles. In comparison, female students' appearance satisfaction was influenced by parents' parenting styles. Specifically, appearance satisfaction and body satisfaction were high when the mother respected the children's opinions, and body satisfaction was rather low when the father was of appearance-pursuing. This result shows that parents need to respect their children's opinions on their appearance and guide them to find their own individuality in order to enhance the children's appearance satisfaction and self-esteem.
