Universities are looking for various methods to enhance educational competence level suitable for the rapidly changing social environment. This study suggests a method to promote academic and educational achievements by reducing drop-out rate from their majors through implementation of pre-survey of satisfaction that revised and complemented survey items. To supplement the CQI method implemented after a general satisfaction survey, a pre-survey of satisfaction was carried out. To consolidate students' competences, this study made prediction and analysis of data with more importance possible using the Random Forest of the machine learning technique that can be applied to AI Medici platform, whose design is underway. By pre-processing the pre-survey of satisfaction, the students information enrolled in classes were defined as an explanatory variable, and they were classified, and a model was created and learning was conducted. For the experimental environment, the algorithms and sklearn library related in Jupyter notebook 3.7.7, Python 3.7 were used together. This study carried out a comparative analysis of change in educational satisfaction survey, carried out after classes, and trends in the drop-out students by reflecting the results of the suggested method in the classes.

The aim of the work that is presented in this paper is to develop the new prior educational materials which use the field trip and to present educational possibilities. The QR codes were used to develop the prior materials. The developed materials applied to elementary students who attended to filed trips in 2012. This was practically achieved by the use of smartphone which enhance the learning experience of a physical visit by providing personalized information with QR codes. The results demonstrate the technology supported physical field trips provides significantly improved learning outcomes, increases students curiosity. Furthermore the findings of the study demonstrate that the application of the specific emerging technologies could facilitate the development of advanced learning experiences in field trips, increasing at a significant level the learning outcomes and the motivation of the participating students.

The purpose of this study was to analyze the college students' acceptance of PatentNOW, which was developed for effective proceeding of patent application education program. Results of this research as follow. First, perceived ease of use positively influenced perceived usefulness. Second, perceived usefulness and perceived ease of use positively influenced attitude toward using and attitude toward using also positively influenced behavioral intention to use. Third, the level of prior knowledge about the patent system and experience of patent application possessed by the users of PatentNOW had a negative effect on the relationship between perceived ease of use and attitude toward using. These results suggested that the teaching method of utilizing PatentNOW should be differentiated according to the level of prior knowledge of the students in order to improve the quality of patent application education.

The purposes of this study are 1) to develop a pre-education program for teaching the basic concepts of systems thinking and STEAM program based on systems thinking and 2) to investigate the effects of the program on middle school students' systems thinking. The subjects were 4 seventh-graders and 4 ninth-graders in a middle school located in the province of Gyeongsangbuk-do. Data related to students' systems thinking was analyzed using the rubrics developed by Hung(2008). The results were reviewed by experts to verify the validity of the rubrics and the reliability of students' system thinking. In addition, the data analyzed with the rubrics, students' awareness of systems thinking, word associations, causal maps and interviews were systematically analyzed to investigate the effects of the program on students' systems thinking. The findings of this study were as follows: First, a pre-education program and teachers' guidebook for teaching and learning the concept of systems thinking and causal maps were developed. The pre-education program consisted of familiar TV entertainment program-Infinite Challenge (Muhandojeon)-with a theme of Global Warming. Second, a STEAM education program based on systems thinking which was composed of 5 steps: Analysis-Design-Build-Assessment-Systems thinking. The major theme of the program was an air extinguisher. The developed STEAM education program had positive effects on improving middle school students' systems thinking abilities such as understanding systems, relations within a system and system generalization. Therefore, it was concluded that the STEAM program could be instrumental for cultivating students' STEAM literacy with improved systems thinking.

The purpose of this study is to propose an effective development of teacher librarians' practice teaching and to identify how much teacher librarians' practice teaching affects their expertise in Korea. For this, two research models are constructed. The first model is to analyze the relationship of variables between the effect of practice teaching and the following variables: pretraining, practice program, advisory teacher, training condition and organizational atmosphere. The second model is to analyze how much the practice teaching affects their role perception and expertise compared with training courses and field experiences. The result is as follow: It is the training program that greatly affects teacher librarians' practice teaching among those variables. And the practice teaching has a positive effect on the ability of role performance. According to the above result, the practice teaching is effective in developing teacher librarians' expertise. And more systematic practice teaching program, enough pretraining and the efforts of advisory teacher are necessary to enhance the effect of teacher librarians' practice teaching.

The purpose of this research is to examine the impacts of persuasion knowledge and pre-attitude on responses to a persuasive entertainment education program. Persuasion knowledge model was adopted as the theoretical frame and information about the sensational identity of entertainment program was used to activate audience's persuasion knowledge(i.e. resistance). Pre-attitude was measured by the degree of concern about the persuasion topic. The experiment was designed by persuasion knowledge(2) ${\times}$ pre-attitude(2) and participants were randomly assigned in one of the conditions and rated their attitude for the persuasion topic. The implicit measure for attitude was included in addition to the explicit measures in order to reveal unconscious attitudinal changes. The results showed that the allegedly effective entertainment-education can confront the resistance of the audience in some contexts. A significant interaction of knowledge ${\times}$ pre-attitude was found in the result of the implicit attitude. The individuals with high concern about the persuasion topic, compared to those with low concern, were more influenced by the entertainment program and also persuasion knowledge. The interaction was not significant on the explicit attitude, which may present the usefulness of the implicit measure in entertainment-education research.
