Based on Smart Phone, this study added and implemented the mobile App to the existing IT agriculture system, which system automatically controlled green house's growth environment. Because the mobile App characterfully possesses high portability, limited resource, mobile wireless network support, enterprise mobile computing support, etc., the hybrid-App should be inevitably adopted. The hybrid App can minimize resource consumption for performing related duties and also, in spite of the mobile device's limits, it can derive high performance, in which facts the system can ensure the service-based architecture's reliance and also, implements the highly sophisticated functionality as well. Through the proposed system, the study expects to contribute to improve quality of life as well as to increase farmer's income through IT-based agriculture system development.

The paper describes the efficient and agile design methodology for the smart phone application, so called the App. Despite the number of smart phones as well as their applications is rapidly being increased recently, the smart and easy methodology for App development is not well developed and not matured in use yet. Since the App is converted to programs or contents from the new ideas, especially, it is important to design and implement the App rapidly and systematically. In order to resolve this problem, we adopt the UI centered approach first of all, emphasizing user-efficient utilization of applications. And we also try to build the whole process in streamlined procedure, making each step reasonable, and the input and output for the step well organized. The design methodology described here is evaluated by designing popular sample application, Scheduler, and also compared with some well-known software design methodologies.

Recently, smart phones are spread out as a universal mobile terminal equipment. Its provide USB interface to connect with various devices. Smart phones may be replaced with high priced monitoring equipments because of portability and mobility as its merit. In addition to that, the various sensor devices detecting surrounding environment of the radioactivity, sodium or electromagnetic waves have been announced. But the plug and play methods of sensor devices have some problem to connect smart phone with USB accessory device. We propose an integrated methodology that can connect smart phone with USB sensor devices and also, we realized USB accessory plug and play with one App that can collect measurement data through various sensor devices.

Smart Home has achieved remarkable developments over the past few decades. In the ICT(Information and Communications Technology) field, 'app ecosystem'-a collection of multiple devices such as mobile phones and tablets, software (operating system and development tools), companies (manufacturers, carriers, app-stores, etc.) and the process through which data is transferred/shared by a user from one device to another device or by the device itself-has come into wide use since the advent of the smart phone. Due to the synergy effect of the 'app ecosystem', it has been applied to various fields such as televisions and automobile industries. As a result, both the Smart TV and connected vehicle have developed their own ecosystem. Although much research has been conducted on these two ecosystems, there is a lack of research regarding 'App Ecosystem based Smart Home' (AESH). This research focuses on the building scenarios based on 'Tracking, Analyzing, Imaging, Deciding, and Acting (T.A.I.D.A), a future prediction method process. Rather than taking an approach from the perspective of providing and applying advanced technology for research on building future scenarios, this paper focuses on research from the perspective of architectural planning. As a result, two future scenarios of AESH are suggested.

O2O service contribute to sales increment by marketing of offline store using online. In particular, O2O business allowed various services by smart-phone due to rapid increase of mobile device use and various services depend on customer's location. This O2O service play major roll in real purchase making of offline store. In smart-phone apps. development for O2O service, recent an Object-oriented Analysis and Design Method, that is, UML is more useful method than Structured Analysis and Design Method. Therefore in this paper, Software analysis and design method which is smart-pone app. for O2O restaurant service is presented. Also it shows that this analysis/design method is very useful for the Restaurant O2O Commercial System production.

The Service had a purpose to be heard through the Smart Phone APP and Smart TV Broadcasting Contents to Foreigner's Language in The Asia Culture Center. This Paper explained how to realize foreigner with Beacon's Signal and IoT gateway provided the voice service with selected his language using AllJoyn Protocol Interface function. IoT Service Platform received the Registration of foreigner's identifier, there sent messages to all devices, which were all IoT gateways, IoT gateway could connect to foreigner's Smart Phone App and heard the Broadcasting contents. If a foreigner went out of Beacon's management distance, the voice App service were released.

This study is in regard to the gas detection system and gas detection method utilizing smart phone. This study includes; 1) the sensor module attached to the smart phone to detect and measure flammable gas or toxic gas; and 2) gas detection APP which is installed inside the smart phone and recognizes the user information and location information automatically by reading RFID tag indicating the user or the location to detect gas through the contact area where RFID and blue tooth reader is installed inside of the above mentioned smart phone, and then measures the combustible gas or toxic gas by operating above mentioned sensor module and obtains the data thus measured, and above mentioned smart phone is characterized by its transmission of the above mentioned user information, location information and measured data which are obtained by above mentioned gas detecting APP to operation server via communication network. With this, reliability for the location detecting gas by the user, the result of the measurement, etc. can be secured. Furthermore, this provides the effect of preventing artificial manipulation at the time of input which is associated with the identification of the user to be measured by utilizing removable sensor module and application or the mistake resulted from wrong input by the user. In addition, by transmitting the measured data from the sensor module carrying out gas detection to operation server, this provides the effect of making it possible to process the data thus collected to a specialized data for combustible gas or toxic gas.

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.
