The information system in which users can utilize to control and to get the filtered information efficiently has appeared. Content-based filtering can reflect content information, and it provides recommendation by comparing the feature information about item and the profile of preference. This has the shortcoming of the varying accuracy of prediction depending on teaming method. This paper suggests the discovery of preference through learning the profile for the content-based filtering. This study improves the accuracy of recommendation through learning the profile according to granting the preference of 6 levels to estimated value in order to solve the problem. Finally, to evaluate the performance of the proposed method, this study applies to MovieLens dataset, and it is compared with the performance of previous studies.

The relationships among students' perceptions of computerized science learning environments, computer-related attitudes. and computer experiences were investigated with a sample of 164 9thgraders (80 boys and 84 girls) from two middle schools. The Computerized Science Learning Environment Inventory (CSLEI) and the Computer-Related Attitudes Scale (CRAS) were administered, and students' computer experiences were examined. Students' perceptions of preferred learning environments were also studied with the preferred form of the CSLEI, and compared with those of actual learning environments. Gender differences in the perceptions of computerized science learning environments, computer-related attitudes, and computer experiences were also studied. Students' perceptions of preferred learning environments were significantly better than those of actual learning environments in all subscales of the CSLEI except gender equity. There was no gender difference in the perceptions of computerized science learning environments. However, boys were found to have more positive computer-related attitudes and more computer experiences than girls. Students' perceptions of computerized science learning environments were significantly correlated with computer-related attitudes in resource adequacy subscale, but not with computer experiences. Significant relationships between computer-related attitudes and computer experiences were also found.

This research evaluated Information Application Mechanism based on university student's preference. In other words, the research content is analyzing what is the most effective learning method for lectures. To obtain this research objective I've done some research in theoretical research and pervious research related to informational mechanism. I also analyzed the degree of understanding in learning-efficiency with students based on lectures using various information mechanisms. For the data gathering I've surveyed 82 students living in Busan, and used the survey sheets to gather data, I made the survey sheet with nominal and interval parts to make the analyzement of data easier. The research result is down below. First, It shows that the students with higher understanding in IT preferred lectures with "PPT"s. Second, The "PPT" preference group thought that the "PPT" teaching method is more effective than other methods. Third, The "WRT" preference group thought that the "WRT" teaching method is more effective than other methods. Forth, Both groups gave each method a 3.08 and 2.95 as a total mean value out on a 1-5 scale showing not much difference. However this research has a research limitation like other researches. In other words, there can be some distortion of information when using the interview method to gather data. The researches from now on will need to organize groups by information mechanisms and research the learning-efficiency with each mechanism.

The purpose of this paper is to find the differences of personality types and learning styles of general students(69) and the gifted in mathematics(66) and sciences(66). 132 subjects, whose academic achievements are in top 1 % level in elementary schools, were selected from the gifted center of the university in Busan. MMTIC(Murphy-Meisgeir Type Indicator for Children) was used to classify personal style inventory(E-I, S-N, T-F and J-P). Adapted form of Grasha & Reichmann's learning style was used to classify 3 pairs: dependent-independent, competitive-collaborative, avoidant-participant. In this paper, we were mainly concerned with the differences of learning styles, and personal types of three groups according to as indices, functions and temperament. One of our results was that there were differences of personality types between general students and the gifted in mathematics and sciences according to as indices, functions and temperament. And there were differences of learning style between three groups according to as dependent-independent, and avoidant-participant.. The gifted in mathematics and sciences prefer to independent and participant learning style in comparison with general students. Finally, there were relation of personality types and learning styles. According to functions and temperament of MMTIC, SF (sensation-feeling) and NF(intuition-feeling) type students prefer to collaborative and participant styles in comparison with ST (sensation-thought) and NT(intuition-thought) type students. And NT(intuition-thought) type students prefer to avoidant styles in comparison with SF(sensation-feeling) and NF(intuition-feeling) type students.

This study commercialization of 5G will enable transformation of university education. This study identifies five attributes (device type, learning place, learning content, learning field and expense payment) and corresponding levels to study the impact of 5G in the future of university education. The attributes and the levels are then combined into few 5G education service alternatives for respondents to rank. 102 students ranked the alternatives based on their preferences and intent to use. Results indicate that the intent to use 5G-based education service was high with 86% and the most important factor was expense payment (37%), followed by learning field (26%), learning content (24%), device type (8%) and learning place (5%). Specifically, students preferred smart device, practical and experiential content, ubiquitous (no limitation of space and time) learning, practical education and free rate when adopting 5G-based education service. These will provide implications to accelerate adoption of and exploitation of 5G for innovating university education.

Students have often experienced difficulties in understanding the concept of the particulate nature of matter despite its importance in chemistry. Although various instructional methods have been suggested for teaching this concept, systematic studies have been rarely conducted. Therefore, this study investigated the effects of drawing and analyzing pictures. Three classes of 7th graders at a coed middle school in Seoul were assigned to the control group, the drawing group, and the analyzing group, respectively. Students were taught about the three states of matter and the motion of molecules for 8 class periods. The instructional effects on student conception, achievement, and science learning motivation were investigated by student visual learning styles. Results revealed that the scores of a conceptions test and a science learning motivation test for both the drawing group and the analyzing group were higher than those for the control group. Additionally, the scores of the science learning motivation test were also found to be higher for students with a more visual learning style than their counterparts.

This study is a descriptive research study conducted to provide useful preliminary data that is helpful for self-initiated learning through a preference trend-based learning method by analyzing the personality types of university students in an area. In this study, the self-administered MBTI form $M^{(R)}$ test was performed on 695 students of 10 departments at K University, from September 18 to 22, 2017, using an automatic scoring system. Collected data was analyzed with descriptive statistics and Chi-square test, using the SPSS Win 22.0 Program, to sort the target students into one of 16 different personality types and examine psychological function and temperament by their personality. Differences in personality type preference by gender were as follows: for judging function, the male students had a strong preference for the T type (thinking type) while the female students showed a high preference for the F type (feeling type), and in the case of the pattern of behavior and lifestyle, the male students and the female students had a strong preference for the P type (perceiving type) and the J type (judging type), respectively. In addition, there were significant differences for each major and each department in personality type, psychological function and temperament. In conclusion, personality type was found to vary by gender, major and department. It would be necessary to develop a manual for learning methods reflecting individual preference.

This study proposed a customer preference estimation model for production recommendation and a method to enhance the performance of product recommendation using the estimated customer preference information. That is, we suggested customer preference estimation model to estimate exactly customer's product preference with his behavior. This model shows the relationship of customer's behaviors with his preferences. The proposed estimation model is optimized by learning the relative weights of customer's behavior variables to have an effect on his preference and enables to estimate exactly his preference. To validate our proposed models, we collected virtual book store data and then made a comparative analysis of our proposed models and a benchmark model in terms of performance results of collaborative filtering for product recommendation. The benchmark model means a prior preference weighting model. The results of our empirical analysis showed that our proposed model performed better results than the benchmark model.

The Purpose of this research is to investigate how Project Based Learning(PBL) cognitive department and among the learner and instructor in the industrial highschool. Theoretical framework for the study is based on PBL, collaborative learning and module learning. The importance of the PBL has been continuously reviewed by many educational researchers. In addition, it was supported by previous research results. Based on theoretical frameworks and previous researches on the PBL provided design principles and method for learning in the industrial highschool. As a result of this study, we have developed and applied to investigate (1) differences between the types of departments(agriculture, industry, commerce) of cognition on learner's and instructor's task solving process, (2) correlation between the type of groups(learner, instructor) and type of departments(agriculture, industry, commerce) cognition on task solving process. The total of 100 learners and 50 instructors from industrial highschool in the study for the period of sixteen weeks. Based on the type of groups and departments, participants were divided into six groups such as learner and instructor of agriculture, industry, commerce department. The result of the study can be summarized as follows: First, in the study, between the types of departments(agriculture, industry, commerce) of cognition on learner's and instructor's task solving process are differences. Second, correlation between the type of groups(learner, instructor) and type of departments(agriculture, industry, commerce) of cognition on task solving process are differences. Although the differences were insignificant for cognition of PBL's help, however, four items(accomplishment, application subject, hereafter application) showed significant differences in performances. The implication of the result indicated the cognition of PBL in the industrial highschool seem significant for departments and subjects characteristic of learning. In future research it is recommended that PBL model designs should consider components of group and department types.
