1 , pp Review of the Techniques for Smart Learning Systems Jaegeol Yim, Sangheon Kim 1 Departmet of Computer Engineering, Dongguk University at Gyeongju, Korea {yim}@dongguk.ac.kr Abstract. This paper surveys smart learning systems in order to identify the techniques needed in implementsation of smart learnng systems. Database management, video streaming, web programming, and so on are essential techniques for smart learning system implementation. There are many database management systems (DBMS) we can use to develop database systems. This paper reviews techniques to use MySQL DBMS. This paper also propose a design of a smart learning system. Keywords: DBMS, MySQL, Smart learning system 1 Introduction Flipped learning is said to be one of the most efficient teaching and learning methods. In flipped learning, students watch lecture videos at home. In the class, they solve interesting problems under the teacher s guide. Nowadays, students watch videos through smart devices while they are on the way home. Therefore, schools should provide a smart learning system. A database of lecture videos, smart applications, content management systems, and streaming servers are essential parts of smart learning systems. There are many database management system (DBMS) with which we can develop database of lecture videos. Among them, this paper reviews techniques to use MySQL DBMS. 2 Related Works Kim et al. [1] introduced a peer report grading system with which students can share their ideas about their answers to assignments. The conceptual model of the system is depicted in Fig. 1. It is a client-server system. A client can be connected to the server via either the Internet or mobile net. The Tomcat is installed as the web server in the server. The server system is written in Java language. MySQL is used as the database management system of the system. The client is written in HTML5 and JavaScript. This paper proposed a self-paced learning system with which students can learn a subject themselves. The system shows many questions at the beginning and evaluates students' answers. Then the system provides student with hints. During the evaluation ISSN: ASTL Copyright 2016 SERSC

2 stage, the system extracts key words from the answers and assigns weights on them. Synonyms of key words are obtained from the WordNet and considered to be correct key words. Fig. 1. A conceptual model of the peer review system Cho etg al. [3] examined the positive effects of the realistic augmented reality in smart learning. Augmented reality is the techniques to integrate real world and virtual world. They concluded that augmented reality contents provides users with better satisfaction. Kang et al. [4] proposed a design of u-learning application for multi-cultural students. The application provides the following menus: Tests, Quiz, Media, Grade, Chat Box, and Video Call. Students can access the u-learning module application anytime and anywhere through PC and mobile devices. Koh and Kim [5] developed a learning system for computer classes. In computer classes, students write a lot of computer programs. This learning system provides teachers with an environment in which they can conveniently upload assignments. The system consists of "Login," "Join member," "Assignment BBS," "My page," and "Q&A BBS" components. The "Assignment BBS" lists all assignments in the order of time. 3 MySQL A database is an application system that stores huge volume of data and provides interfaces for creating and managing the stored data. In order to develop a database system, we use a database management system (DBMS). MySQL is one of the most popular relational database management systems (RDBMS). Visit in order to download the MySQL installer package. After unzipping the package, execute setup.exe. Then, MySQL is installed under the MySQL folder as shown in Fig Copyright 2016 SERSC

3 Show databases; shows databases on the MySQL server as shown in Fig. 3. create database wine creates a database named wine as shown in Fig. 3. show tables after use wine shows all tables belonging to the wine database. There is no table in wine at this moment. create table customers create the customers table in the database, wine in this case as shown in Figure 4. We can store data in the table by using insert command as shown in Figure 5. Fig. 2. MySQL is installed under the MySQL folder Fig. 3. show command Fig. 4.

This studio allows users to easily produce augmented reality videos and virtual reality videos. Everybody watches augmented reality videos everyday on televisions. Most of television programs including weather forecasting, realistic news broadcasting, realistic educational programs, and tourism programs are full of augmented reality. This studio provides users with equipment and software products with which they can efficiently produce augmented reality videos. This studio also provides users with 360 cameras and accessories including drones with which they can conveniently take 360 pictures. The studio also provides users with software products with which they can efficiently organize footage and stitch it all together. One of the most important components of the smart learning system is the content management system (CMS). The CMS allows teachers to conveniently upload their lecture videos and allows students to conveniently find the video they want to watch. In addition to providing users with convenient user interface, the CMS should also provide abundant application program interface with which software developers can efficiently develop applications. 5 Conclusions This paper surveyed smart learning systems. Existing systems emphasized on 1) the positive effects of augmented reality and virtual reality, 2) self-paced learning, 3) management of assignments, and so on in smart learning. Considering the advantages of existing systems, this paper proposed a design of a smart learning system 4 Copyright 2016 SERSC
