The results of this study are as following: 1. The CAI porgram was developed on health and food life units. The program contains 12 classes on health and food life in two floppy diskettes. It consisted of total 9,000 lines and 76 frame and takes two hours to study this program. This program could be used in educational computers an could be utilized for unit learing tutorial. It was composed of three parts-unit learning, finding maze, and finding food. In the unit learning part, the learning contents in health and food life units were structured and presented. In finding maze and food part, the basic and the applied problems were presented with game. The characteristics of this program were as followings: (1)This program was able to bring learners’motivation due to the strategies of tutorial and instructional game and they can interestingly learn the program for themselves. (2) The learner could practive the learning contents repeatedly and unit learning while playing the gaming, (3) The learner himself can review and supplement the learning contents without teacher’s help. (4) This program was developed to unit learning on health and food life, on the other hand so far many CAI programs for home economics teaching were developed for studying separate learning units. 2. To effectively utilize this program, the guide book for the student and the teacher was developed. It contained method of using the program, introduction of the program, review of the program, the program objectives, the learning contents, and the keys to progress the program.

In order to strengthen the information security of the organization, it is important to invest in the information security facility, but the information security awareness of the organization members is also very important. Effective education is needed to raise awareness of this information security. However, the method of collective education utilized by most organizations is not very effective. Educational methods using serious games can be a good alternative. Educational methods using serious games have already proved effective through various cases and researches and are used in many fields. In this paper, we design and implement a game program to improve the awareness of individual information security policy importance. The training was conducted for the members of the organization and the change of awareness about the importance of individual information security policy was examined through analysis of evaluation data before and after the training.

The purpose of this study is to find out the impact of classes using a game-based student response system on learning engagement. It is an experimental study that compares learning engagement in classes (experimental groups) and lecture-style classes (comparative groups) that utilize GSRS in nursing education. A total of 211 nursing students participated from October 2019 to December 2019. The differences in learning engagement between the two groups were analyzed as t-test and correlation analysis was conducted on related factors. There was a difference between the comparison group and the experimental group in overall learning engagement(p=.013) and emotional engagement(p=.002). This is meaningful in that it has verified the learning engagement effect of the GSRS for the first time in Korea.

This study explores the features of sociocultural context of experiment classes taught by a science subject teacher. Two experiment classes on electric circuit for fifth graders were observed and video recorded. The data was also collected through student interviews and teacher interviews. Using the cultural historical activity theory, we extracted the six sociocultural factors and analyzed their interactions. This study could identify that four features of the sociocultural context of the cases. First, the rules of science classes were not decided by the teacher, but formed and modified through the negotiation between the teacher and students or between the students. Second, elementary students played a game, i.e. 'Countdown game', during their electricity experiments, which had both positive and negative influences on science learning. Third, the science teacher feels a limit on life guidance because of the position as a subject teacher in an elementary school. Lastly, although the science teacher had enough time to prepare science classes, there was no guarantee of the improvement of teaching quality. Based on the results of this study, educational implications are discussed in terms of teaching science experiments and of the science subject teacher system.

Wave propagation with high transverse deflection could affect the stability of the ball in its trajectory. For low stiffness balls similar to soccer and volleyball balls, the waves are more noticeable in comparison to other balls like ping-pong ball. On the other hand, the soccer balls are under heavy impact loads from shoots and contacting different objects in the field. The maximum recorded speed of a soccer ball after kicking is the 211 km/hr and the average maximum speed is around 112 km/hr. Therefore, in such speeds the aerodynamic forces become important which are directly related to geometrical shape of the ball. In this regard, the wave propagation in soccer ball is examined in the current study using large deformation shear deformable formulations. Classical relations of stress-strain components are taken into consideration along with minimum total energy principle. The final derived relations were solved by using harmonic differential quadrature method. The results are generally presented ion term of phase velocity as function of different influencing parameters of the materials, geometry and mass of the ball.
