The main two applications of the Genetic Algorithms(GA) are the optimization and the machine learning. Machine Learning has two objectives that make the complex system learn its environment and produce the proper output of a system. The machine learning using the Genetic Algorithms is called GA machine learning or genetic-based machine learning (GBML). The machine learning is different from the optimization problems in finding the rule set. In optimization problems, the population of GA should converge into the best individual because optimization problems, the population of GA should converge into the best individual because their objective is the production of the individual near the optimal solution. On the contrary, the machine learning systems need to find the set of cooperative rules. There are two methods in GBML, Michigan method and Pittsburgh method. The former is that each rule is expressed with a string, the latter is that the set of rules is coded into a string. Th classifier system of Holland is the representative model of the Michigan method. The classifier systems arrange the strength of classifiers of classifier list using the message list. In this method, the real time process and on-line learning is possible because a set of rule is adjusted on-line. A classifier system has three major components: Performance system, apportionment of credit system, rule discovery system. In this paper, we solve the food search problem with the learning and evolution of an artificial ant using the learning classifier system.

In multi-objective scheduling problems, the objectives are usually in conflict. To obtain a satisfactory compromise and resolve the issue of NP-hardness, most existing works have suggested employing meta-heuristic methods, such as genetic algorithms. In this research, we propose a novel data-driven approach for generating a single solution that compromises multiple rules pursuing different objectives. The proposed method uses a data mining technique, namely, random forests, in order to extract the logics of several historic schedules and aggregate those. Since it involves learning predictive models, future schedules with the same previous objectives can be easily and quickly obtained by applying new production data into the models. The proposed approach is illustrated with a simulation study, where it appears to successfully produce a new solution showing balanced scheduling performances.

The purpose of this study is to development of a teaching-learning model for active learning in engineering education. For this, the adequacy between educational objectives and active learning activities is verified and furthermore an "active learning teaching-learning model" is suggested. This suggested teaching-learning model is expected to supplement weakness of traditional lecture-type teaching-learning activity. Based on the literature review, first, the representative activities of active learning were derived. there are twenty active learning activities, which compose of five of individual learning activity, five of pair-learning activity and five of group-learning activity, and five of alternative- learning activity. In addition, a survey on adequacy between designed active learning activities and learning outcomes were conducted to ten educational experts. Lawshe's content validity calculation method was applied to analyze the validity of this study. Second, five teaching-learning principles, such as thinking, interaction, expression, reflection, and evaluation were derived to develop an "active learning teaching-learning model" which supplements lecture-type classes and then the "TIERA teaching-learning model" which consists of five stages was designed. Finally, based on the survey on educational experts, adequate active learning activities were proposed to apply in each stage of the "TIERA teaching-learning model" and as a result the TIERA model's active learning activities were developed. The result of this study shows that some activities of active learning are appropriate to induce high cognitive learning skills from the learners even in traditional lecture-type classrooms and therefore this study suggests meaningful direction to new paradigm of teaching-learning for engineering education. This study also suggests that instructors of engineering education can turn their traditional teaching-learning activities into dynamic learning activities by utilizing "active learning teaching-learning model".

This study aimed to analyze the appropriateness of chemistry teaching-learning programs for the gifted in science in middle school gifted classes and to propose improvements. For this study, 5 chemistry teaching-learning 4-6 hour programs developed for science gifted classes by Korea Education Development Institute (KEDI) and 3 chemistry teaching-learning programs developed for science gifted classes by three middle schools in K province were selected. A standard model for gifted education programs was used as tool for analyzing the program targets, program contents, teaching-learning methods, and assessment items. The results showed that all chemistry teaching-learning programs for the gifted in science presented well attainable objectives in the program targets. However, most program targets did not offer differentiated objectives from the general education. Program contents of KEDI stresses intensified education, and also presented a high ratio of sub-elements of creativity, which can enhance gifted creativity. On the other hand, program contents developed by three middle schools focused on acceleration in advancement, and presented low ratio of creativity sub-elements, which could be insufficient in enhancing gifted creativity. Differentiated and personalized, integrated science and interscience, updated research contents were hardly found in programs developed by KEDI and three middle schools. However, teaching-learning methods were composed to fit the learning objectives in the teaching process and the procedures, and were made to self-directed learning. There were no assessment for the feedback after class. Therefore, teaching-learning programs for the gifted in science should be developed further in order to fulfill the objectives of gifted education and gifted characteristics. Also, it is necessary to construct infrastructure to carry out the developed teaching-learning programs.

Objectives: The purpose of the study was to investigate the relationship between professor trust and learning flow in allied health students and to provide the basic data for the improvement of curriculum and teaching method. Methods: A self-reported questionnaire was filled out by 263 allied health students. The questionnaire consisted of 27 questions of professor trust by Likert 5 scale and 29 questions of learning flow by Likert 6 scale. Cronbach's alpha in this study was 0.97 in professor trust, 0.96 in learning flow. The data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, correlation and stepwise multiple regressions. Results: The score was 3.72 in professor trust and 3.46 in learning flow. There were positive correlations between learning flow and professor trust including intimacy, professional, teaching skills and leadership. Stepwise multiple regression analysis revealed that learning flow was related with professor trust. Conclusions: The learning flow depends on professor trust. Based on the research, improvement directions that put strong emphasis on low section of professor trust and learning flow must be placed.

This study attempts to develop e-learning contents for the "fashion information analysis," which should be performed in combination of theory and practice in fashion education, in a recent Web-based education environment. The e-learning contents are developed by using the three steps of analysis, design and development. In order to analyze the requirements of curricula, the status and content of fashion information related curricular provided by general universities and cyber universities are analyzed, and then on the basis of this analysis the education objectives and detailed contents of e-learning contents are determined. Design and development of e-learning contents consist of the types, education menus and education form. The types of e-learning contents are developed into an education form combined with tutorial and practice/activity types. The education menus are comprised of syllabic, the profiles of professors and students, announcements, questions and answers regarding respect subjects, materials, and notes. Meanwhile, the education form consists of the following sections: "Before the Learning", "Learning", "Review Questions", "Final Review", "References", and "Practice", "Before the Learning" consists of two parts of a theory lecture that is composed of video clips and Power-Point presentations, and practice that consists of an audio(or video) lecture and illustration or Photoshop software execution window.

This study develops and applies a service learning course that integrates university curriculum with the local community in housing and interior design. The results of the study are as follows. First, the service learning course of the housing and interior design was developed as a six-week lecture based on the project model with the theme of housing for the socially disadvantaged. Second, this course was implemented with faculty, students, interior designers, and service recipients to engage in activities to improve the educational environment of local child centers. Next, students engaged in the service learning course and continuously conducted reflection activities to enhance the effectiveness of learning. In reflection activities, students assessed that self-directed capabilities increased as has employing the coordination and applicability to meet identified community needs. Finally, faculty, students, and experts (including institutional experts and supervising departments) evaluated course practice and educational outcomes. Experts assessed that the course clarified course objectives, utilized various learning strategies, and showed that the structural reflection mode of learners and professors was overwhelmingly positive. The results indicated that service-learning courses enable students to integrate academic study with social work to better understand course content through direct engagements in experience learning. Furthermore, students are empowered by participation in public services that benefit service clients and consultants as students take more personal responsibility for learning.

In this paper, we proposed comparison of software education units according to 2015 Revised National Curriculum. Comparative analysis of 6 Practical Arts textbooks was conducted especially on the software education units. The analysis criteria were decided to be unit system, unit structure, learning objectives, the way of placing contents, activities, supporting materials, providing resources, and evaluation. As a result, the software education units have secured a lot of quantity compared to the total number of units. And the affective domain of the learning objectives is shown to be lacking. All the textbooks were uniformly arranged the component of contents described in 2015 revised national curriculum. Cooperative activities are strengthened compared to the previouse curriculum. On the other hand, evaluations have a large variation among textbooks and some have fewer types.

Design subjects have become popular in the engineering education. In these subjects, an active learning skill was introduced to students. Students have to decide a theme and the way how to study it and to find answers by themselves. This learning method was developed in the early year courses in the University of Tokushima. The common learning curriculum among whole university adopted this design subjects from 2005 of the school year and eleven more new subjects started. "Roots finding" is one of them and the objectives are to gain abilities of self-study through the research on a particular subject, and make report then presenting them. Self-learning ability, research ability and presentation skills were enhanced through this subject.
