Reading Pen is used mostly in educational purpose, yet its possibility is great as an input device for various IT devices. Reading Pen recognizes tiny dot patterns printed in papers, converts the patterns to corresponding codes, and plays audio contents that match the codes. Recognizing dot patterns and converting to the codes are the main function of Reading Pens, on which we focus and propose a novel algorithm. Such technology is never open to public and this paper is the first open attempt in this area. We test the algorithm and obtain 85% recognition ratio.

This study analyzes the current status of drone journalism in Korean broadcasting industry, with a case study of TV Chosun Company's drone use for news gathering. It analyzes TV Chosun's record of drone logs between 2014 and 2018. The log consists of date, time, news content, users, machine and on-air date. In 2014, the total of 31 cases of using drones for news gathering is identified, while in 2018, the frequency increases to 60, with a gradual, annual increase, making the total frequency of 160, during the period between 2014 and 2018. This means that the broadcasting company used the drone news gathering system every week. The analysis also reveals that the company used this drone news gathering system mostly in the metropolitan area in Korea, amounting to more than 76 per cent of its total use: 31.3 per cent in Seoul, 36.9 per cent in Kyunggi, and 8.1 percent in Incheon. The system was more frequently used in the summer and autumn than the winter and spring. Interestingly, it was first popularly used for disaster related news, but the use of drone for social and other issues is increasing every year, which may imply its diverse use in the future.

The digital contents industry has now become the most important industry in the 21st century. Among the various digital contents industries, the animation industry has emerged as a higher value-added culture contents business with a strong possibility of growth from the field of image and character to the copyright area. Yet, the overall market structure has not been consolidated except for a few successful projects because of the sharp decline in domestic animation and the upward trend in global animation business. Due to reduced investment in producing TV animations, OSMU is an essential alternative for the animation industry. In this research, we aim to analyze the development of the domestic animation industries by studying the actual condition of OSMU for broadcasting contents.

Nowadays there are gradually the importance issues of embedded software for productivity as the fusion and complexity of industry. Especially, people are recognizing the importance of reliability within the embedded software systems(e.g. weapons and medical equipments, etc.). It makes currently mention of software reliability on ISO/IEC 9126, 12119, etc.. However, it is insufficient for the embedded software area in spite of being mentioned the generic software. To do this, we suggest our embedded software reliability assessment through extracting the embedded software meaurement items from reliability assessment items of ISO/IEC 9126, 12119 series.

Recently, Impulse radars using UWB technologies are widely use for measuring distance, or for transmitting uncompressed high resolution videos. However, since the UWB band spans over octave bands, it is not easy to design such a system. Wide band impedance matching is required for antennas and other RF area. In this study, we designed and fabricated sinuous antenna for 3~6 GHz octave band application. We also designed and attached a dielectric lens to improved the directional gain of the antenna. The gain of the antenna was 6~10 dBi. The dielectric lens attached sinuous antenna was used to transmit HD video data. The maximum reach distance was 90 meter with 10mW power.

In this paper, we propose a scheduling method for signal measurement and control algorithm execution in a multi-motor drive controller. The multi-motor controller which is used for vehicle control receives position/velocity command and performs position/velocity control and current control. Internal resource allocation and control algorithm execution timing are very important when one microcontroller is used for multi-motor drives. The control performance of the velocity control system is verified by varying ADC(Analog to Digital Converter) conversion timing and algorithm execution timing using real experiments.

In this paper, we propose a fuse controller which is used for storing the optimal value or the correction value for the surrounding product of the IoT applications and it is implemented serial communication circuit using a single pin. Because of the proposed single pin protocol is simpler in the hardware than the conventional $I^2C$ and SPI using two or more pins, it is suitable for the area of small amount of data transmission. The function of the one pin protocol is verified by logic simulation and the FPGA test board and it is fabricated using CMOS 0.35um technology. It is expected to use the IoT product that require the low power consumption and simple hardware.

Intelligent Transportation Systems (ITS) is aimed to implement IT(Information Technology) to develop the next-generation transportation system in order to improve traffic conditions. In order to provide traffic information, the methods that provide available traffic informations to the public are needed. In this paper, analysis of the transportation applications in smart-phone and currently available methods of traffic information's sharing and providing were discussed. Finally, OPEN API was discussed and shows its effectiveness for transportation information area especially in smart phone.

As Power Line has been already installed over 60% of a residential area all over the world, Broadband Service has been possible using high-speed PLC(Power Line Communication) without new access line installed for Internet access. Because of such reason, PLC is researched as the most suitable service for Last Mile Solution. But, Power Line is designed for transmitting electric power, so peripheral Wireless Communication System is affected by a leak of electric wave. In this paper, we propose a High Performance Notch Filter algorithm in comparison with a existing notch filter for reduction of interference between existing Wireless Communication Service and Power Line Service. In addition, we implement the Notch Filter emulator appling a High Performance Notch Filter and using a embedded board.

Text Mining is a research area of retrieving high quality hidden information such as patterns, trends, or distributions through analyzing unformatted text. Basically, since text mining assumes an unstructured text, it needs to be represented as a simple text model for analyzing it. So far, most frequently used model is VSM(Vector Space Model), in which a text is represented as a bag of words. However, recently much researches tried to apply a graph-based text model for representing semantic relationships between words. In this paper, we survey research trends of graph-based text representation models for text mining. Additionally, we also discuss about future models of graph-based text mining.
