A streaming service is considered as an important fact to listen musics at mobile device in the popular smart-phone era. An apple's HTTP Live Streaming method is used in iOS and a RTSP(Real-time Streaming Protocol) method is used in Android OS. A Wowza Media Sever will be used to support both apple and android mobile streaming. This paper describes a design and implementation of smart-phone app. to record user's songs by userself with smart-phone recording function, upload to the streaming server and to service real-time mobile streaming play for an user's selected song and provide song sharing SNS functions.

본 프로젝트는 고객과 택배기사가 배송과정에서 겪는 불편함을 해소하기 위해 App과 IoT센서를 연동하여 배송과정의 편의성을 제공하는 무인 택배함이다. 기존 택배함의 비밀번호를 사용하는 방식이 아닌 택배함에 부착되어있는 NFC 태그 스캔을 통하여 편리하게 물품을 배송 및 보관할 수 있도록 하였다. App은 택배기사와 고객으로 나뉘어 있으며 택배기사 App의 주요 기능은 운송장 번호를 스캔하여 물품을 보관할 여러 택배함 중 하나를 선택하여 해당 택배함의 도어락을 제어하는 기능이 있으며, 고객 App의 주요 기능은 NFC 스캔을 통해 물품이 보관된 택배함 또는 보관할 택배함을 선택하여 도어락을 제어하는 기능이 있다. 그 외에 택배기사 App은 배송 목록 조회, 내 정보 확인 등의 서비스를 제공하고 있으며, 고객 App은 택배 예약, 예약 조회 등의 서비스를 제공하고 있다. 택배함은 와이파이 모듈을 통해 서버와 통신할 수 있도록 하였으며, 충격센서와 Mp3 모듈을 사용하여 택배함에 충격을 가하면 경보음이 울리도록 설계하였다.

Recently, as the uncontact service is activated in earnest due to the Corona 19 virus, the necessity of system development to provide non-face-to-face contact remote medical service has increased. In this study, we propose a smart healthcare system, Rm_She(Remote Medical Smart Healthcare System). Rm_She can collect and manage various vital signs information by connecting various healthcare products that detect bio-signals based on IoT to one application. The health check app (HC_app) is used to connect vital sign measurement devices to a wireless LAN and receive vital sign values from the HC_app. Then, the vital signs are output to the user on the smartphone, and the corresponding information is transmitted to the healthcare management server. The healthcare server receives the measured values and stores them in a database, and the stored measured values are provided as a web service so that medical staff can remotely monitor them in real time.

In this paper, we proceeded a study on the Hybrid RF based development of the smart phone Application skin disease monitoring using CMOS camera. we proposed an image transfer technology which can use the CMOS camera and we developed the smart phone application which can be possible to use a remote monitoring for skin disease. Image transfer technology using Hybrid RF communication applied for WiFi using CMOS camera. We implemented the function which can use a remote monitoring using Wi-Fi. These suggestion can be a good example for endoscopic applications using hybrid RF based smart phone application of skin disease monitoring using CMOS camera.

Smart phones are very convenient for communication, but you need to not to forget to change to silent mode when you go to church or cinema. Many people used to forget changing their cell phones to silent mode. In this paper, we have developed an android smart phone app. for automatic changing silent mode, which exploited smart phones' GPS and computing capability. According to the GPS location data and time, this app. will automatically change a cell phone to silent mode. We believe that this app. would provide us a lot of convenience.

This study aims to establish and apply a mobile office app for approving the achievements of tasks assigned to each person to investigate resulting satisfaction. This is done first by implementing the app for approval in a company with smart phones to enable tasks to be carried out any time and anywhere while the mobile office environment changes the method of carrying out tasks. More efficient work environment is expected if the system implemented in this study is improved in cooperation with customer's requirements. Matters for improving work efficiency added to the approval management system through this app will contribute to efficiently and continuously improving the mobile office environment to enhance productivity and efficiency of a company.

Spread of smart devices increases, the App Store market is formed so huge, even at this point, every day the scale is increasing now. As a result, for the benefit of companies and private individuals, malicious apps that threaten the security of smart devices, have appeared occasionally in the App Store. Security of the terminal, has issued various solutions through research at many universities and companies, and country. However, solutions for research and policy approaches that are blocking the procedure to register the application malicious app, so that it is not registered in the App Store, Only company that operates the app store is doing it. And the reference is also insufficient, various problems have occurred. In this study, after analyzing the problem of the security policy of the current App Store, presenting the breaking point.

Recently, since fine dust has become a serious social problem, air purifiers are in the spotlight as a countermeasure against this. Therefore, in this paper, we conducted R&D on the Smart Autonomous Moving Air Purifier System. The developed Smart Autonomous Moving Air Purifier can improve the limitations of the standard used area of existing air purifiers and perform an air purification function efficiently. In addition, we developed App and Web-based programs together for convenient use of Smart Autonomous Moving Air Purifier. Easily operate three air purification modes (Selection mode, Autonomous highest zone mode, Autonomous instant purification mode) through the App and conveniently monitor statistical values (Recent data, Total data, Warning) anywhere through the Web. And, we showed through test that the proposed Smart Autonomous Moving Air Purifier is more efficient than existing air purifiers.
