Problem-based learning (PBL) is applied to various subjects for the sake of learners' creative thinking, problem-solving skills, presentation skills, confidence, self-directed learning, cooperation, and for the communication skills required in a rapidly changing society. Among them, the English language-an official language-is invested in 2.3 times more than other subjects, according to the English education company Yoon's Teacher. Therefore, PBL is an important learning method. However, the reality is that teacher-centered instruction, acquiring knowledge of the best answers only, and traditional evaluations are the main subjects. In order to supplement these weak points, this study designed a learning model for English subjects based on Barrows & Myers (2002) and the analyze, design, develop, implement, and evaluate (ADDIE) model. As a result of a PBL English class based on the ADDIE model, the learners were able to improve their presentation skills by 86%, their interest in learning by 86%, their understanding of learning by 86%, and cooperation by 100%. As such, studies on designing the learning model should be carried out continuously to achieve the purpose of 21st century English education, which is to improve learners' communication skills and information processing skills.

India is a gigantic market with a population of 1.2 billion and an economy that is growing at the second-fastest pace in the world. The volume of trade between India and Korea has been sharply increased with the increase of dispute since 2000. Although avoidance of disputes is always a priority, it is also important to prepare methods of dispute resolution which are efficient and economical. So, understanding of Indian dispute resolution system is a necessary requirement for successful business operation with Indian companies. This article analyzed and compared with the various ways of Indian ADR such as negotiation, mediation, conciliation, Lok Adalat and arbitration in order to help the Korean traders who enter into business with the Indian companies to settle their disputes efficiently. In conclusion, this article suggests the following ways to overcome problems of dispute with Indian companies: First, the Korean companies should recognize the characteristics of Indian ADR Ways respectively. Second, the Korean companies should utilize the conciliation or the mediation in small claim but arbitration in large claim. Third, Write a contract and insert the KCAB's standard arbitration clause in their contract.

Operating Systems is a discipline which handles abstract concepts and techniques. However, most of OS courses have been textbook-oriented theoretical classes. Theoretical classes lead to the decline in the understanding of a lecture, and hurt their concentration. Many instructors have tried to make use of educational tools to help students understand lectures and arouse interests. This paper describes the design and implementation of a CPU scheduling simulator which shows the operation of process scheduling algorithms visually. The academic achievement evaluation for 2010's students and 2011's and t-test results show that the differences of the correct answer ratio for the exam about CPU scheduling algorithms are meaningful. The survey shows that the simulator is useful as an educational tool which causes the interests and enhances the understanding of a lecture, this teaching method is effective to develop problem solving skills.

Reading ability has been widely considered as one of the basic skills that every student should be conversant with because higher level of thinking power can be acquired through reading. Reading education allows students to build correct way of thinking as well as foster critical thinking ability. However, it can be observed that reading education has not been well addressed accordingly in schools mainly because teachers have only limited amount of time and ability to cope with. In this paper, we developed a Web-based peer evaluation system for improving reading and writing ability so that students are allowed to exchange ideas freely on the Web after reading books as well as evaluate other students' writings, which would facilitate reflective thinking through the computer-mediated communication activities. Students become graders of other students' writings so that they are exposed to different opinions and ideas through which deeper thoughts can be obtained. The learner-centered learning activity instead of teacher-centered may benefit students as well as teachers and the system implementing this idea shows that both students' attitudes and preferences were improved as the result of applying the system to a local elementary school.

This study presents a model that enables to predict road surface temperature using neural network theory. Historical road surface temperature data were collected from Road Weather Information System. They used for the calibration of the model. The neural network was designed to predict surface temperature after 1-hour, 2-hour, and 3-hour from now. The developed model was performed on Cheongwon-Sangju highway to test. As a result, the standard deviation of the difference of the predicted and observed was $1.27^{\circ}C$, $0.55^{\circ}C$ and $1.43^{\circ}C$, respectively. Also, comparing the predicted surface temperature and the actual data, R2 was found to be 0.985, 0.923, and 0.903, respectively. It can be concluded that the explanatory power of the model seems to be high.

The aims of this paper were to review the usable possibility of the educational App Inventor Program in the field of programming education and to develop programming teaching materials that can overcome limitations of the established programming instruction. The study showed that the learners' motivations were strengthened through smart device programs. Containing the elements of STEAM, the teaching materials were developed for the logical and systematic learning that deals with elementary students' real-life situations, and that helps children follow the procedures of software development. By introducing the Waterfall Model to the process of programming, students are able to follow the software developers' thinking process. In addition, beyond the simplistic programming language and simply acquiring related knowledge, the App Inventor programming was designed to enhance students' higher-order thinking skills such as creativity, problem solving ability, collaborative thinking, and so forth.

Computer education currently executed at middle schools showed problems of system of education curriculum, repetition, and lack of consistent system as a result of analyzing index for information and communication technology curriculum, and related literatures, and most of the education contents have difficulty to nurture logic thinking and problem-solving ability since they are composed mainly of software function learning. Concerning this issue, this study suggests an innovated computer education curriculum with reinforced information ethics field with computer principle, algorithm, and programming, in other words, a corrected and supplemented version of former content system based on computer science guidance cases of ACM computer science curriculum model of USA, computer science curriculum of Florida state, and Unplugged Project(http://www.unplugged.canterbury.ac.nz) judging that introduction of computer science factors are desperate to improve computer education curriculum in middle schools.

Small and medium-sized firms are increasingly dependent on the knowledge and expertise of the supply chain as a whole to innovate and improve supply chain performance. This research examines the capabilities that enable firms to collaborate successfully, and aims to identify the determinants of SCM performance of the suppliers participating in supply chains managed by Global Korean companies. This study proposes the technology support, the collaboration with tier two companies, incentives and information sharing as major research variables, and collected the survey responses from 58 domestics suppliers. The statistical results indicate that the incentives, technology support and the collaboration with tier two firms influence the level of co-work with the firm leading supply chain, and that information sharing has some impact on SCM performance of the suppliers. But on the contrary to our expectation, the co-work with the firm leading supply chain has only moderate impact on SCM performance with p value just over 5%. We conclude this paper with some suggestions for future research.

In the knowledge-based society today, most knowledge is the integrated one which is difficult to be classified into subjects rather than the knowledge of a single subject. Thus, integrated thinking, which integrated knowledge is preferentially acquired first and then can be also associated with imagination and artistic sensitivity, is simultaneously required in order that we have a problem-solving capability in our daily life. STEAM education(science, technology, engineering, arts and mathematics) is one of the educational methods to improve this problem-solving capability as well as integrated thinking. This research developed materials for STEAM education which can be applied to the 6th grade curriculum of elementary school mathematics, then input it, and analyzed how it impacts with students' attitudes toward mathematics. Unit 3 'Prism' and Pyramid' were restructured and replaced by classes such as 'Spaghetti Project' or 'Paper Craft'. Unit 4 'Several Solid Figure' was taught as a class of 'EDUCUBE'. Unit 6 'Proportional Graph' was taught as a class of 'Creating my own bracelet'. After having this class, we found that mathematics class applied STEAM also has a positive effect on the mathematical attitude of students. Many students said that math is fun and gets more interesting after having math class applied STEAM and we come to know that they have positive awareness of mathematics.
