With the rapid growth of smart phone technologies, mobile user's demands for using services provided by existing web or portal cites are highly increased. These services, however, are designed for the environment of desktop PCs or laptops in general, so it requires lots of costs for corrections and has difficulties for system protection to use in current mobile devices. In this paper, we design and implement a middleware for android-based smart phone apps to cooperate with a portal system with minimum corrections and function configuration. Our middleware system is working as an interface between an existing portal system and mobile devices to provide harmonious usage and safe system protection.

In addition to direct sales to consumers, the direct-to-consumers (D2C) strategy, which provides specialized experiences and services, communicates closely with a consumer's perspective. This tendency is related to the recent trend wherein the luxury fashion system is being transformed into a new luxury. Therefore, this study analyzes the development of online D2C platforms and investigates the characteristics of new luxury from the functional, symbolic, and experiential dimension perspectives based on mobile apps, which is becoming increasingly important among online D2C platforms. Based on the study results, the premium of new luxury fashion displayed in Louis Vuitton's mobile D2C platform in terms of product utility and functionality is newly defined as a usable luxury experience. Moreover, from the heritage perspective, based on the cultural sympathy of the brand contents, we determine that an attachment can be formed between new luxury fashion consumers and brands. Additionally, the personalization service and experiential content on the D2C platform can directly afford emotional and bonding induced brand immersion in a playful way.

현재 사용되고 있는 냉동창고 재고관리 프로그램은 폐쇄 클라이언트 서버 환경에서 운용되고 있어 유지보수에 많은 비용과 인력이 소요될 뿐만 아니라 소비자인 화주에게 제공되는 서비스가 전무하며, 기본적인 수 발주를 위해서 팩스나 전화를 이용하므로 업무가 비효율적이며 오류와 부정확성 등의 문제가 발생하고 있다. 이러한 문제를 해결하기 위하여 본 논문에서는 다양한 모바일 운영체제에서 화주에게 서비스를 제공하는 모바일 웹앱을 설계하고 구현한다. 구현된 시스템에서 화주는 다양한 모바일기기를 이용하여 수 발주 업무, 재고량 조회 등의 서비스를 제공받아 업무를 처리할 수 있어 사용자만족도를 향상시켰다. 또한 모바일 운영체제에 독립적인 웹앱의 형태로 제공되어 사용자의 다양한 모바일 기기에서 운영될 수 있으며 실시간으로 유지보수를 제공할 수 있는 장점이 있다.

최근 스마트폰의 활용이 급격하게 증가하면서 스마트폰을 위한 다양한 서비스, 즉 어플리케이션(앱)이 개발되고 있다. 이러한 컴퓨팅 패러다임의 변화에 따라 통계 분야에서도 스마트폰을 위한 통계지리정보서비스 개발이 요구된다. 현재까지 대부분의 서비스는 웹을 기반으로 제공되고 있으며, 최근에 국내 통계청에서 S-통계내비게이터 모바일 서비스를 제공하고 있다. 그러나 이러한 서비스들은 사용자 인터페이스 및 기능적인 측면에서 여러 가지 문제점을 지닌다. 특히 단순 통계지리정보서비스만을 제공함으로써 사용자에게 다양한 분석 결과를 제공하지 못한다. 이 논문에서는 사용자에게 보다 유용한 복합 통계지리정보서비스를 제공할 수 있는 새로운 통계지리정보 앱을 제안한다. 제안한 통계지리정보 앱은 다양한 복합 통계 분석 결과를 지리정보와 함께 제공함으로써, 사용자들에게 양질의 통계지리정보서비스 결과를 제공할 수 있다.

공장 사업장 등에서 발생되는 매연은 대기오염의 원인이 될 뿐만 아니라 인체에도 나쁜 영향을 미친다. 따라서 대기오염방지를 위해 배출되는 대기오염물질을 측정하고 이를 관리하여 대기오염을 신속히 파악하고 사전에 방지하기 위한 서비스가 필요하다. 본 논문에서는 광학센싱을 이용해 굴뚝연기의 혼탁도를 측정하고 이를 다양한 모바일 운영체제에서 측정결과를 실시간으로 검색할 수 있는 모바일 웹앱을 설계하고 구현한다. 구현된 시스템에서 사용자는 다양한 모바일기기를 이용하여 굴뚝연기의 혼탁도와 VOC 오염도에 대하여 여러 가지 조건으로 검색할 수 있으며 사용자 정의값을 설정하고 이를 초과하는 경우에 지정된 번호로 알림 서비스를 제공 받을 수 있다. 또한 모바일 운영체제에 독립적인 웹앱의 형태로 제공되어 사용자의 다양한 모바일 기기에서 운영될 수 있으며 실시간으로 유지보수를 제공할 수 있는 장점이 있다.

In this paper, MEMS embedded system design implemented the sensor events via analyzing the characteristics that dynamically happened to an abnormal status in power IoT environments in order to guarantee a maintainable operation. We used three kinds of tools in this paper, at first Bluetooth Low Energy (BLE) technology which is a suitable protocol that provides a low data rate, low power consumption, and low-cost sensor applications. Secondly LSM6DSOX, a system-in-module containing a 3-axis digital accelerometer and gyroscope with low-power features for optimal motion. Thirdly BM1422AGMV Digital Magnetometer IC, a 3-axis magnetic sensor with an I2C interface and a magnetic measurable range of ±120 uT, which incorporates magneto-impedance elements to detect the magnetic field when the current flowed in the power devices. The proposed MEMS system was developed based on an nRF5340 System on Chip (SoC), previously compared to the standalone embedded system without bluetooth technology via mobile App. And also, MEMS embedded system with BLE 5.0 technology broadcasted the MEMS system status to Android mobile server. The experiment results enhanced the performance of MEMS system design by combination of sensors, BLE technology and mobile application.

The aim of this paper is to improve the usability of Mobile Maps by allowing more people to use. To figure out better UX/UI, I evaluated usability for Mobile Applications from various materials such as literatures and blogs for qualitative methods and interviews and questionnaires about satisfaction of Naver and Daum for quantitative methods. So, We know that a map app is important and it is affected by force and profile on the portal site than its own features, because, not often in everyday life. Even though people do not use Mobile Map Applications frequently, we need to improve usability to make anybody use them easily by minimizing depth and button designs.

The many companies and developers develop new mobile applications for serving to users. But, most of it is disappeared in a brief. Because Many applications weren't satisfy the needs of user. In this paper, it analysis to reason short life of mobile application in the smart terminals and mobile applications. Therefore, we develop dynamic user usability analysis system of applications to solve the problem. User usability analysis method is surveyed users and masters at present and then occurs high cost. In this paper, we develop dynamic user usability analysis system for real users. If usage of mobile applications upgrading, benefit of developers increased and serviced target contents to users.

Communication through smartphones is creating a new paradigm of mobile communication beyond the restrictions of mobility and space. The mobile instant messengers of the smartphone, which began on the desktop environment, are providing various communication features, including multimedia contents, texts, and voice. Kindergartens and nurseries are using Websites, phones, SMS, printed materials, handwritten notifications, etc. to communicate with the parents. IsPlus was developed to facilitate the communication between the parents and the teachers, including exchanges of pictures and videos, chatting, and attendance management using smartphones. This is meaningful in that it is an early smartphone mobile messenger for educational institutions for infants and preschoolers. This study presented a new approach to the development of a mobile messenger for a specific group of users by analyzing the user environment, communication types, application planning process and interface design development using storytelling.
