This study is to investigate into the factors that influence the use of a military logistics information system in Korean army. We developed the research model based on DTPB (Decomposed Theory of Planned Behavior) because the DTBP is an appropriate model in a mandatary using environment through the study of previous technology-acceptance models. A questionnaire survey was conducted with Korean army solders and civilian components who use the army logistics information system and 266 valid questionnaires are recovered. The collected data were analyzed by SPSS and AMOS. The results show that perceived usefulness and ease of use did not affect the attitude of the use intention. The influence of colleagues and upper class officers was all satisfactory and computer self-efficiency affected perceived control of behavior. The results of this study will contribute to the further use of the military logistics information system and future development strategy.

The purpose of this study is for consideration of the flapper fashion (1924-1928) in Jazz Age (1919-1929) of America and the influences of it on modern fashion. This study is started from the latest fashion trend which is pursuing it's inspiration into the Jazz Age, the 20s. The etimology of 'flapper' was based on mines is 'flap' such as 'flutter of skirt hemline', 'hands', 'arms', 'wings' and a slang which was applied to young women from 1830. In 20th century it has meant not only new American women but also their fashion and attitude. The designs of flapper fashion were expressed by simplicity, functionality, nudity and rhythm. Simplicity was the best value of this time and the simple image was considered the smartest. Functionality was represented by straight boyish style and loose baggy silhouette that was related to free dome. Nudity was expressed by revealing of legs, arms, backs in shapes and see-through by materials. It was related to sexual attraction and point to youth. Rhythm of flapper fashion expressed optical effect of movement. Using of light material was deep related to freedom of flappers, speed, rhythmical Jazz and dancing. The influences of flapper fashion were giving an opportunity that changed fashion leader from high class to young popular group and simple design of flapper fashion effected to modernization and popularization of American apparel business. And it influenced American casual fashion which was known as brightness, youth and openhearted mood. So flapper fashion can be reganded as the starting point of the street fashion of the 20th century.

Even though the animation industry has been growth since 2011, there is still imitation by public stereotype which insists that animation is only able to cover the young age group and is not the proper genre of art to convey a social or a philosophical agenda. However, describes the philosophical agenda of 'social class' and 'life and death' in the limited space by expressing characteristics and background of fish through its own way. Thus, it shows how animation goes beyond aforementioned limits. Straying from traditional happy-ending, it criticizes present social problems by telling despite fishes' effort they cannot escape from structural contradictions. The drawing technique in musical expresses the character's ideology and attitude to make people think about how we will behave in the face of life and death. Therefore the purpose of this paper is analyzing director Lee Dae-hee's animation and present the genre expandability of animation.

The national curriculum includes the problem solving process, algorithms, and programming of SW education. The education using robots is one of attractive alternatives for students who have no interest of SW or are poor at programming. We have developed a courseware using robots for SW education based on paper art activities with narrative storytelling to enhance students' creative thinking and problem solving within limitation of class time in schools. We apply the courseware and obtained the result of pre and post-test on the creative problem solving ability of third graders in the elementary school The four factors of creative problem solving have shown significantly increase. In addition, it had an significant effects for understanding robot technology and for learning attitude using robots of SW or programming.

We are developing a micro-solid propellant rocket array thruster for simple attitude control of a 10 kg class micro-spacecraft. The prototype has ø 0.8 mm solid propellant micro-rockets arrayed at a pitch of 1.2 mm on a 22 x 22 mm substrate. In previous studies, an impulse thrust of 4.6 x 10$^{-4}$ Ns was obtained in vacuum, but we found the problems of unacceptably low ignition success rate and incomplete combustion. This paper describes experiments to improve the ignition rate. In order to achieve this goal, we tried to solidify paste-like ignition aid (RK) on the ignition heaters with strong adhesion. To make the paste-like RK, isoamyl acetate was added to RK powder. We tested 9 rockets, but only 2 rockets were ignited with huge ignition energy. This is because the heat con-duction between the ignition heater and the RK was too low to ignite the RK, since dried RK had a lot of pores. Also, a large cavity was sometimes found just above the ignition heater.

The purpose of this study was to investigate whether students' creative problem-solving skills improve through project-based courses. Rather than measuring overall competencies, the focus was specifically on measuring the improvement of problem-solving skills. The study involved a literature review, the design of project-based courses, and the assessment and analysis of students' competencies before and after the courses. The results of the study are as follows: Firstly, the measurement of students' creative problem-solving skills before and after the project-based courses indicated an overall improvement in the five dimensions of problem identification, analytical thinking, flexible thinking, alternative generation, and a proactive attitude. Secondly, significant correlations were found among these five dimensions, particularly strong correlations were observed between problem identification and alternative generation, problem identification and analytical thinking, and analytical thinking and alternative generation. To generalize the findings of this study, further research is needed to apply similar approaches in different types of courses and across various universities and departments.

The purpose of this study is to develop a discussion-centered teaching and learning model for nurturing creative and convergence talents. Regarding the research method, a draft model on discussion-centered teaching and learning was devised, and the model was completed through expert validation. The final draft was revised and supplemented by verifying how valid the model was when applied in class by using the derived final draft. Compared with the draft on discussion-centered teaching and learning model, the final model focused on text-reading emphasis, methods of questioning, and question generation strategies, excluding jigsaw discussions. The discussion-centered teaching and learning model developed in this study is expected to help instructors foster creative and convergence talents. Three suggestions have been provided to effectively apply this model to the field. First, an attitude of listening and respect is required during a discussion. Second, a plan should be considered on how to induce active participation of learners participating in the discussion. Third, the importance of managing discussion time was emphasized.
