Before smartphones, English learners used to organize words in their notebooks. As smartphones became more popular over time, more people started to study by storing words in word book apps than notebooks. Users will be able to study words anytime, anywhere via their smartphones. These word-field apps are a way for users to enter data themselves. However, this paper designed and implemented an app that automatically enters words using vision system and letter recognition. The app recognizes areas painted with highlighter first, then recognizes words within the highlighter area and organizes them into tables. It also helps to understand how certain words are used in contexts in certain English bodies with simple actions. Because the data of words can have multiple words in a particular body, the database schema was designed in a one-to-many relationship between the images taken with the camera and the words contained in that body. The differentiated advantages of this app are as follows: First, it increases the time efficiency of studying. Second, it improves learners' vocabulary by learning based on context. These advantages are described in detail in this paper through practical research materials and techniques. The app's platform used Apple Inc.'s iOS. Character recognition, a key technology in the app, utilizes OpenCV's library and Apple Inc.'s CoreML.

New technologies such as big data analysis and artificial intelligence are evolving based on convergence with information technology and are affecting all industries. To cultivate problem-solving skills in line with this trend, universities are providing programming education as a basic liberal art course. However, students who take programming courses as liberal arts are having a lot of difficulties in connecting the problem-solving process with actual programming. Even at the stage of putting together basic programming elements and applying them to problem-solving, they tend to feel that they can't do anything or give up. To solve this problem, this paper proposes a method of applying a goal-based scenario to programming education. The goal-based scenario is one of the case-based learning approaches such as problem-based learning and action learning. Based on the scenarios, students can clearly understand the context/situation in which particular knowledge is used and learn to apply the earned knowledge to solving specific problems. Therefore, programming learning based on these scenarios can be used as a tool that can be applied to solving and analyzing similar problems, away from syntax and result-oriented education. In this study, we analyze the existing Python liberal arts programming education and present the effects and considerations of the method of applying the goal-based scenario.

With the recent development of the Internet, big changes have occurred in all areas of daily life. Because the Internet brings many opportunities beyond time and space constraints. This strength stands out especially in the commercial market. If the Internet is connected, transactions can be made regardless of the border. However, as the frequency of use increases, the problem is also increasing. In this paper, the cross-border consumer issues were presented due to the development of e-commerce. Today, the problem of cross-border e-commerce consumers is increasing in proportion to the increase in Internet use. Cross-border e-commerce has the advantage of broadening consumers' choices, but the structural nature of Internet transactions makes it difficult to remedy consumer damage. To solve this problem, we looked into legal and institutional responses that are being implemented in major countries, including Korea. But mostly about business-to-business transactions, failing to embrace the issue of e-commerce between consumers and businesses. In addition, the legal system for e-commerce is in the process of overhauling, but its effect is insufficient. To solve these consumer problems, we propose the need to seek legal and policy aspects to find out what form of 'inter-border e-commerce' is taking place in the practice of trading and alternative solutions to resolve consumer disputes and remedy damages.
