Parkinson's disease(PD) is one of the three major senile diseases and the incidence rate is increasing worldwide as the population ages. And as the disease progresses, time and economic costs increase, so it is important to understand the progress of the disease and to diagnose it early In this paper, we propose a method for pre-screening Parkinson's disease using a smartphone. The contents of the developed application are composed of tapping, tremor, spiral drawing, and gait based on Part III of the Unified Parkinson's Disease Rating Scale. This can be used to quantitatively diagnose Bradykinesia, Tremor and Postural Instability, which are known as motility symptoms of Parkinson's disease, and to monitor the progress of symptoms. This method is expected to be useful for the diagnosis and treatment of Parkinson's disease.

The core parties operating application stores can be categorized into two major groups. One of which is an application store that offers manufacturing and platforms while the other being telecommunication company orientated. Each group has an affiliated partnership. In a larger group, there are three major types of partnership such as "partnership that causes an increase in traffic","partnership through the sales within the application contents" and "partnership through advertisements". In order to find out whether teenagers and potential consumers in their twenties would prefer a "message-type advertising" or an "application-type advertising". Through experiment, we also figured out which type of advertising worked more effectively between the two given types.

Raspberry Pi is a credit card-sized computer with support for a large number of input and output peripherals. This makes it the perfect platform for interaction with many different devices and for usage in a wide range of applications. When combined with Wi-Fi, it can communicate remotely, therefore increasing its suitability for the construction of wireless sensor nodes. In addition, data processing and decision-making can be based on artificial intelligence, what is performed in developed testbed on the example of monitoring and determining the confidence of fire. In this paper, we demonstrated the usage of Raspberry Pi as a sensor web node for fire-safety monitoring in a building. When the UV-flame sensors detect a flame as thin as that of a candle, the Raspberry Pi sends a push-message to notify the assigned smartphone of the on-site situation through the GCM server. A mobile app was developed to provide a real-time video streaming service in order to determine a false alarm. If an emergency occurs, one can immediately call for help.

Korea has high quality level of ICT Technologies, however it still have a long way to go before invigoration of ICT in agriculture industry. The government of Korea supply to agriculture ICT systems, however these are the enclosed type and insufficient the level of connectivity, compatibility, and integrity between ICT systems. Farmers can not share crop information and one system can not use with others in combination. Recently, IoT(Internet of Things) become popular to emphasize the vision of a global internet and ICT industry. The IoT is a critical technology that leads future internet generation. We believe that IoT will change status of agriculture industry and appearance of various agriculture business model. Using IoT technology is provided a platform of opportunities to optimize work processes and efficient use of energy, time and labour in farm. It can automatically control temperature, humidity, sunshine system and so on for optimal growth conditions at greenhouse and plant factory. Growth setting can even be controlled and monitored crop condition and disease by a smartphone app or PC. It is possible to improve quality of farming and farm product. We suggest that construction of IoT platform through open API in agriculture industry.

This research aimed to design and develop a mobile-website mixed business model and smartphone based mobile application for the purpose of mobile fashion content distribution. We have implemented a mobile interface and trading system supporting self production of content, use, share, and user's self-up. And we proposed its market access strategy for the expansion of fashion contents transactions. To do this, the existing status of research and benchmarking for mobile app of fashion contents related were studied. As a result of the study, Android, iOS-based mobile applications were developed, but there are some business problems such as low awareness, low entry barriers, and the poor fashion content compared to the size of industry. Because this system provide the fashion contents of affiliated companies to users, it needs to expand cooperation and to promote the partnership with fashion blog, cafes, and fashion magazines.

Recently, with the popularization of smartphones, augmented reality has become even more familiar to the public as an application that can provide realistic images as a tool for location-based services. Therefore, as a location-based application for smartphones that is appropriate for the application of augmented reality technology, the study develops a golf information system. Golf is the sport for which we should exactly know the accurate shape or distance to the destinations or obstacles, so the sport is suitable for applying the augmented reality technology. Even though the sport of golf has constantly increasing population to play it with the popularization of it, presently released golf-related smartphone apps are established as 2D images or in GPS basis; thus, they lack a sense of realism unfortunately. Thereupon, this study develops a golf information system by modifying and complementing usefully Mixare, the open source for augmented reality, for the sport of golf into an augmented reality-based system that can provide various information according to the actual environment of the golf course and describes how to apply it actually to the golf course.

In this paper, we propose a walking aid system that guides route to visually impaired people in order to recognize uncertain obstacles based on tactile stimulation. The proposed system is composed of the touch-based obstacle detection module, the obstacle height detection module, and the route guidance algorithms. The touch-based obstacle detection module detects each obstacle, which is located at left, right, and front of a visually impaired person by stimulating his thumb with the rotational force of the servomotor. The obstacle height detection module integrates detected data by the linear arrangement of ultrasonic sensors to identify the height of an obstacle about 3 of-phase(i.e., high, medium, low). The proposed route guidance algorithm guides an optimized path to the visually impaired person by updating his current position information based on the signal of the built-in GPS receiver in smartphone. In addition, the route guidance algorithm delivers information with speech to a visually impaired person through Bluetooth commuination in the developed route guidance app. The proposed system can create a path to avoid the obstacles by recognizing the placed situation of the obstacles with exploring the uncertain path.

The study is underway with the goal of developing an app that will replace vernier calipers using a smartphone's high-performance camera. The specifications of the camera mounted on recent smart phones have evolved so that usually has a 12 Mpixels of image sensor and its size of the pixel is 1.4㎛ and the size of the image sensor is 1 / 2.55 in. The proposed algorithm will apply to develop a precision measuring application that will compete with the Vernier calipers. Most existing applications cannot guarantee an accuracy in scale because the scale of the ruler displayed on the image is unclear or the size of the measurement object varies depending on the distance between the camera and the measurement object. In addition, another accurate measuring tools using lasers are also available, but they are limited because they are expensive. Therefore, if easy-to-carry and precise applications are developed, it is possible to substitute existing measurement tools. The proposed correction algorithm is an algorithm that automatically corrects the distorted source image using the shape and size information of the known template. The e-calipers are applications that display the distance when the area to be measured is specified in the corrected image.
