In this paper, we describe the current state of speech recognition technology and identify the basic speech recognition technology and algorithms first, and then explain the code flow of API necessary for speech recognition technology. We use the application programming interface (API) of Google, Naver, and Daum KaKao, which have the most famous search engine among the speech recognition APIs, to create a voice recognition app in the Android studio tool. Then, we perform a speech recognition experiment on people's standard words and dialects according to gender, age, and region, and then organize the recognition rates into a table. Experiments were conducted on the Gyeongsang-do, Chungcheong-do, and Jeolla-do provinces where the degree of tongues was severe. And Comparative experiments were also conducted on standardized dialects. Based on the resultant sentences, the accuracy of the sentence is checked based on spacing of words, final consonant, postposition, and words and the number of each error is represented by a number. As a result, we aim to introduce the advantages of each API according to the speech recognition rate, and to establish a basic framework for the most efficient use.

Though programming education has been stressed recently, the elementary, middle, and high school students are having trouble in programming education. Most programming environments for them are based on block coding, which hinders them from moving to text coding. The traditional PC environment has also troubles such as maintenance problems. In this situation, mobile applications can be considered as alternative programming environments. This paper addresses the design and implementation of coding applications for mobile devices. As a prototype, a Scheme interpreter mobile app is proposed, where Scheme is used for programming courses at MIT since it supports multi-paradigm programming. The implementation has the advantage of not consuming the network bandwidth since it is designed as a standalone application. According to the benchmark result, the execution time on Android devices, relative to that on a desktop, was 131% for the Derivative and 157% for the Tak. Further, the maximum execution times for the benchmark programs on the Android device were 19.8ms for the Derivative and 131.15ms for the Tak benchmark. This confirms that when selecting an Android device for programming education purposes, there are no significant constraints for training.

The mobile internet has grown ubiquitous across the globe with the widespread use of smart devices. However, the designs of modern mobile operating systems and their applications limit content retrieval with mobile applications. The mobile internet is not as accessible as the traditional web, having more man-made restrictions and lacking a unified approach for crawling and content retrieval. In this study, we propose an automatic and scalable mobile application content crawler, which can recognize the interaction paths of mobile applications, representing them as interaction graphs and automatically collecting content according to the graphs in a parallel manner. The crawler was verified by retrieving content from 50 non-game applications from the Google Play Store using the Android platform. The experiment showed the efficiency and scalability potential of our crawler for large-scale mobile internet content retrieval.

4차 산업과 현대사회의 급격한 발전으로 인하여 현대인들에게 있어 스마트폰은 절대적 필수품으로 여겨진다. 또한 최근 인터넷 및 스마트 기기를 사용하는 '스마트 실버 세대'의 스마트폰 이용률이 증가해가는 추세이다. 본 논문에서는 '스마트 실버 세대'를 위해 불필요하거나 사용하지 않는 어플리케이션의 제거를 한눈에 볼 수 있도록 하여 어플리케이션을 제거(삭제)함에 있어 용이하고 편리함을 갖춘 '클린 앱' 어플리케이션을 제안한다. 더 나아가 '스마트 실버 세대'의 스마트폰 활성화를 위해 스마트폰 기기에 설치된 어플리케이션들을 사용빈도를 체크하고, 마지막으로 사용된 날짜를 확인 하여 불필요한 어플리케이션을 보다 정확하게 삭제 시킬 수 있도록 한다.

본 논문에서는 4차 산업 혁명의 주요 기술 중 하나인 '연결 및 표시 기술'에서 사람의 눈으로 보는 표시 기술 중 하나인 증강현실(AR)과 가상현실(VR)를 융합한 MR기술을 활용한 앱 어플리케이션에서 제공하는 콘텐츠를 이용자들이 쉽게 접근해서 사용할 수 있도록 제안한다. 증강현실을 나타내는 방법 중 하나인 Marker를 이용한 기술을 통해서 관광 콘텐츠를 제공할 수 있도록 프로토타입을 구현하였다. 사용자가 앱 어플리케이션을 통해 Marker를 인식하게 되면, 거기서 관광 관련 콘텐츠를 스마트폰 화면에 띄어서 제공되는 콘텐츠를 자유롭게 이용 할 수 있는 효율성을 제공할 수 있다.

요즘 스마트폰을 사용하는 사람의 수가 늘어감에 따라 무분별한 스마트폰 사용으로 인한 스마트폰 중독의 사태가 일어나고 있다. 특히, 본인이 스마트 폰을 소유 하지는 않지만 부모의 스마트 폰을 가지고 사용하는 영유아들은 자제력이 부족할 뿐만 아니라 중독의 위험이 청소년이나 어른들보다 높은 실정이다. 스마트폰을 직접 소유한 10대 청소년뿐만 아니라, 어른들 역시 무분별한 스마트폰 사용으로 일상생활에 지장이 많다. 본 논문에서는 자제력이 부족한 청소년이나 어른들에게 스스로 사용시간 설정을 통하여 무분별한 스마트폰의 사용시간을 자제 시킬 수 있는 스마트폰 사용제한 어플리케이션을 설계하고 구현하였다.
