Due to smart phones introduced since 2007, mobile contents production become activated and with this trend, attention among different age groups to production of mobile games has been growing. Whereas in the past, development of games was the domain of developers equipped with technical knowledge, provision of editor-type engines in recent times is lowering the high barrier of entry to game production. This paper proposes an event-based module design method from the perspective of general users, aimed at producing games by oneself with a Unity 3D, one of editor-type game engines. This is to plan behaviors and roles in the unit of modules in the whole process of a game to be in line with the perspective of game production by one person. Each module includes diverse events that express game characteristics. In addition, the script function provided by the Unity 3D is appropriate to embody the proposed module structure and utilizes the Unity 3D. Lastly, this study produce a simple 3D mobile casual game in order to verify whether effective game production from the planning to the development is possible through the proposed method.

This study aims to compare and analyse computer curriculum and textbooks of South Korea and North Korea in order to provide the basis for unifying the Informatics Education. Result of this study follows : First, there isn't any course for Informatics Education in the elementary school but it was requisitely carried 2 hours per week in secondary school in North Korea. But contents of curriculum is much different according to the level of school : genius secondary school, first secondary school, general secondary schol. In especially, Informatics Education had centered in genius secondary school. Second, in comparison of computer textbooks used in South and North Korea, we found that most contents of South Korea textbook was selected equally from all scope whereas those in North Korea were not contained the newest contents(e.g. Internet, Multimedia). But in contrast to South Korea textbook, there was BASIC programing course for improving problem-solving skills in North Korea textbook.

This study is to develop a web-based career guidance system to be a help making a decision on one's occupation, which is important for a person's life. As career development education for higher grades of elementary school aims at providing basic knowledge necessary for career choice and forming a basic attitude toward occupation and values, it is desirable to carry out the guidance of a variety of occupations on the basis of personal interest and aptitude of individual students. Previously, however, most studies have remained at the level where simply test results are notified. Therefore, the study administered a career development test fit for higher grades of elementary school who are at the stage of potential career choice and developed a web-based career guidance system in which suitable occupation types are advised of based on the results. Beyond notifying test results, the developed career guidance system presents 3 excellent intelligences, rather than converting test results into scores. Thus, it is expected that the system will help students understand their areas of excellent intelligence, efficiently study related occupation types and duties, and learn to have awareness and make a better decision in relation to their career.

To cope actively in the knowledge based society, we deepen a specialty territory and magnify this by applying Information Communications Technology(ICT) effectively. It needs the ability that it will be able to solve the problem from daily life effectively. Accordingly Ministry of Education & Resource Development of Korea make an effort for ICT application education. In spite of this effort, digital divide problem is serious socially and the computer subject is not adopted with formal subject from school. In this study, we analyzed the computer application ability gap and recognized the importance of computer education by analyzing the difference in computer application ability between the students who take a computer class and who do not take a class. Also by comparing the difference of computer application ability between the city and rural student, we tried to find a solution to reduce the regional disparity.

To solve the problems of lack of professional knowledge and teaching method for Information Ethics in the school, In this study we designed a curriculum model on point of students of educational colleges for Information Ethics Education(IEE) in the college that many researchers had mentioned. The contents in IEE curriculum included opinions of them who will be teachers of elementary or middle, high schools in the future. Also, For imbalance of reverse functions-oriented contents of information society in present, In the first, we made up 5 content fields: "In formation Society", "In formation Ethics", "Cyber-Etiquette", "Reverse Functions and Conquest", "Teaching method". In the second, we reflected opinions and demands of active teachers. Finally, In oder to check the validity of curriculum that designed in this study, we had expert group of education examine the validity of IEE curriculum design.

In this paper, A lane tracking algoritm is proposed for lane departure warning system. To eliminate perspective effect, input image is converted into Bird's View by inverse perspective mapping. Next, suitable features are extracted for lane detection. Using clustering and lane similarity function with noise suppression features are extracted. Finally, lane model is calculated using RANSAC and lane model is tracked using Kalman Filter. Experimental results show that the proposed algorithm can be processed within 20ms and its detection rate approximately 90% on the highway in a variety of environments.

The purpose of this study was to investigate changes in geological contents knowledge and self-confidence before and after the geological field trips. Fifty seven undergraduate students at a national university of education participated in this study. The questionnaires were developed by the researcher to serve the purpose. Findings were as follows. First, before and after the geological field trip, there was no significant difference in changes of geological content knowledge (p<.05). However, participants' self-confidence about the geological field trip changed significantly (p<.01). Second, there were no significant differences in changes of both variables in terms of gender (p<.05). And in this study, participants were grouped into two: science track that selected science areas and non-science track with social study selected in the college scholastic ability test. There were also no significant differences in changes of geological contents knowledge and self-confidence in terms of science or non-science track (p<.05). Third, in terms of the geological content knowledge, 24 pre-service teachers showed an increase, 12 students unchanged, and the 21 participants decreased. In contrast, per participants' self-confidence about the geological field trip, fifty three students indicated an increase with only one participant unchanged, and three preservice teachers decreased on the score. Finally, after the geological field trip, participants' comments indicated that they could feel the mystery of nature with the mind of a great experience. As a result, data showed that pre-service teachers became interested in geology, and motivated more in learning geological area than ever.

There is more than one way to conduct scientific research. In addressing the concern for educating the gifted in science towards achieving objectives of fostering their research skill, its elements need be explored and discussed by first admitting that various methodologies and features coexist in the name of scientific research. This study explores the various features of research skill presented as scientific process skills focusing on the students' experimental designing. Of course, there are several other domains included facets of research skill, such as problem finding, scientific knowledge, and self-efficacy. A Diet Cola Test (DCT) (Fowler. 1990) for digging into science process skills as an elements of research skills was administered to 705 students from 3rd to 10th grade, who enrolled the gifted education centers in Korea. Date was interpreted and analyzed based on the focus of Science education perspectives and research methods related to creative thinking and problem-based learning. But I eschew establishing and generalizing fixed constitutes of research skill from this research.

We developed a micro UAV based rapid mapping system that provides geospatial information of target areas in a rapid and automatic way. Users can operate the system easily although they are inexperienced in UAV operation and photogrammetric processes. For the aerial data acquisition, we constructed a micro UAV system mounted with a digital camera, a GPS/IMU, and a control board for the sensor integration and synchronization. We also developed a flight planning software and data processing software for the generation of geo-spatial information. The processing software operates automatically with a high speed to perform data quality control, image matching, georeferencing, and orthoimage generation. With the system, we have generated individual ortho-images within 30 minutes from 57 images of 3cm resolution acquired from a target area of $400m{\times}300m$.

This thesis analyzed the effects of cooperative learning blended with TAI(Team Assisted Individualization) and STAD(Student Team Achievement Division) models on the students' ability of problem solving in mathematics in order to discover what kind of effects would give to their ability of that, and would promote their disposition and attitude to learn mathematics. The results of this study were as follows : First, the learning method blended with TAI and STAD models was more effective in the students' ability of problem solving in mathematics than traditional learning method because of the blended model's characteristics; positive interdependence, individual accountability, team recognition, curriculum materials. Second, the learning method blended with TAI and STAD models was more effective in sub-elements - self-confidence, adaptability, will, curiosity and value - of mathematical disposition than traditional learning method. And the learning method blended with TAI and STAD models was more effective in sub-elements - self-consciousness of mathematics and interests - of mathematical attitude than traditional learning method. In conclusion, the learning method blended with TAI and STAD models could affect to not only the students' ability of problem solving in mathematics but also the students' several affective factors.
