개인용 휴대전화는 다양한 형태로 발전 되어 왔다. 그 동안 국내 통신 시장은 피쳐폰이라고 불리는 단순 전화, 문자 위주의 서비스만을 제공하는 하드웨어 기반의 서비스가 대부분이었다. 몇 년 전부터 PDA와 전화 기능을 기반으로 한 하드웨어가 출시되기 시작하였으나 사용 및 운영의 불편함으로 인해 수요의 폭을 넓히지 못 하였고, 2007년 Apple사의 iPhone 출시를 기점으로 전 세계적으로 다양한 형태의 스마트 폰이 출시되기 시작하였다. 또한 휴대폰 공급 업자들이 제공하는 일방적인 서비스에 만족하지 않고 사용자가 원하는 방향에 필요한 컨텐츠를 다양하게 제공할 수 있는 소프트웨어 마켓의 등장으로 스마트 폰은 그 사용자 층이 매년 큰 폭으로 확대되고 있다. 최근 스마트폰은 글로벌 경기 침체 속에서도 13%대의 성장률(2009년 3/4분기)를 보이며 세계 휴대폰 시장의 중심으로 자리 잡고 있다. 또 사용자의 요구를 충족 시키기 위해서는 다양한 플랫폼의 개발자가 양성 되고 있으며 다양한 어플리케이션을 제공하기 위해 노력하고 있다. 본 논문에서는 다양한 플렛폼 기반의 개발 환경을 소개하고 향후 개발자들이 접목할 수 있는 개발 도구 및 응용 방법을 비교 분석함으로써 스마트폰을 기반으로 한 최적화 어플리케이션의 개발을 촉진 시키고자 한다.

This paper is about environment-based low-code and no-code execution platform and execution method that combines hybrid and native apps. In detail, this paper describes the Low-Code/No-Code execution structure that combines the advantages of hybrid and native apps. It supports the iPhone and Android phones simultaneously, supports various templates, and avoids developer-oriented development methods based on the production process of coding-free apps and the produced apps play the role of Java virtual machine (VM). The Low-Code /No-Code (LCNC) development platform is a visual integrated development environment that allows non-technical developers to drag and drop application components to develop mobile or web applications. It provides the functions to manage dependencies that are packaged into small modules such as widgets and dynamically loads when needed, to apply model-view-controller (MVC) pattern, and to handle document object model (DOM). In the Low-Code/No-Code system, the widget calls the AppOS API provided by the UCMS platform to deliver the necessary requests to AppOS. The AppOS API provides authentication/authorization, online to offline (O2O), commerce, messaging, social publishing, and vision. It includes providing the functionality of vision.

Demand for machine learning systems continues to grow, and cloud machine learning platforms are widely used to meet this demand. Recently, the performance improvement of the application processor of smartphones has become an opportunity for the machine learning platform to move from the cloud to On-Device AI, and mobile applications equipped with machine learning functions are required. In this paper, machine learning tools for mobile applications are investigated and compared the characteristics of these tools.

The methods that are used for receiving data from attached devices under real-time preemptive multi-task operating system (OS) by general processors can be categorized as polling and interrupt driven. The technical approach to these methods may be different due to the application specific scheduling policy of the OS and the programming architecture of the flight software. It is one of the most important requirements on the development of the flight software to process the data received from satellite subsystems or components with the exact timeliness and accuracy. This paper presents the analysis of the I/O method of device related scheduling mechanism and the reliable data I/O methods between processor and devices.

Virtualization technique of OS-level is a new paradigm for deploying applications, and is attracting attention as a technology to replace traditional virtualization technique, VM (Virtual Machine). Especially, docker containers are capable of distributing application images faster and more efficient than before by applying layered image structures and union mount point to existing linux container. These characteristics of containers can only be used in layered file systems that support snapshot functionality, so it is required to select appropriate layered file systems according to the characteristics of the containerized application. We examine the characteristics of representative layered file systems and conduct write performance evaluations of each layered file systems according to the operating principles of the layered file system, Allocate-on-Demand and Copy-up. We also suggest the method of determining a appropriate layered file system principle for unknown containerized application by learning block I/O usage history of each layered file system principles in artificial neural network. Finally we validate effectiveness of artificial neural network created from block I/O history of each layered file system principles.

This study aims at developing the high speed/intelligent machining system suing the plug/play method of an open architecture controller. The plug/play technology by the Application Specific Function (ASF), can readily implement the open architecture controller into various machining system or other automatic equipments. For the open architecture controller, this study developed the open HMI, screen editor, ASF, visual builder, and controller OS technology as software components. On the other hand, we developed the I/O module and main board as control hardware system. This study, as an example, presents integration of individual component technologies for the plug/play type open architecture CNC system.

The aim of this study was to develop a mobile application 'Beat Processing Device (BPD)' to record and quantify the data for the performance accuracy of rhythm production. BPD has been developed in three phases. First, we reviewed studies that used rhythm as main intervention strategy to improve cognitive functioning of older adults, and derived four basic rhythm idioms. Second, we developed an iOS-based mobile application, optimized the device, the instrument tone, and the measurement variables through preliminary test. Lastly, we tested the mobile application by comparing the performance data obtained from MIDI and BPD from 60 older adults. The device was shown to be reliable and consistent with other mode of measurement and analysis. Conclusively, BPD can be a useful tool for assessing rhythm production ability in the course of cognitive skills training.

This paper discusses a study on a mobile application aimed at making public transportation more convenient for people with mobility challenges on both Android and iOS platforms. The research analyzes the limitations and weaknesses of existing mobile applications for public transportation from the perspective of individuals with mobility challenges. The goal is to overcome these limitations and provide an optimized user experience. The motivation behind this research stems from the recognition that people with mobility challenges face difficulties in their daily commute, and current public transportation applications do not adequately cater to their needs. Consequently, the study aims to develop a specialized mobile application for individuals with mobility challenges to support them in achieving greater independence in their daily travels.

Many people are now enjoying mobile games using various smartphone platforms. However, we have to develop games separately for each smart device platforms so far. Cocos2d-x, a game development framework is released to solve this problem. As a multiplatform version of the existing Cocos2d, Cocos2d-x can make one source code run on various platforms. It is an open software that is able to be used by everyone, and when using it, mobile games can be developed easily based on C++ and OpenGL. In this paper, we implemented a PC laboratory decorating game application, named ILove501, using Cocos2d-x. The 501 is a room number of our PC lab. ILove501 includes an educational feature of solving quizzes in order to highlight positive effects of game. For implementation of a multiplatform game, ILove501 was developed in Windows and iOS environment at the same time, and we verified the results of the execution by porting on a variety of devices such as Android, iPhone, iPad and Galaxy Tab.
