Sony has recently launched a remote play service that connects PC and PlayStation4 using the Internet. This service enables the network connection between the external network and PS4 network. After the service released, additional security threats may arise in remote environments with new services. Therefore, those threats should have been analyzed. In this paper, as applying threat modeling to remote play system, threats have been analyzed and identified. After cost-effective and usability analysis, finally, reasonable security measure of each threat has been suggested.

As various smartphones users are increasing rapidly, the more contents they keep in their devices, however, the larger necessity for the effective and easy management of their files they want. To satisfy this need, we propose an integrated multimedia files management system, H5Station. By using H5Station client, users can connect to the H5Station server running on their own PC, and manage their multimedia files effectively, and enjoy every file they have. The H5Station client is developed by using HTML5 standard technology. Therefore H5Station client can run on any HTML5-supported browser. Main functions of the H5Station are as follows: configuring user settings, charting the distribution of user files, upload/download/deletion of files, synchronizing files' metadata between client and server, playing user-selected files, searching files users want, and finally creating user-customized buttons. Through these functions, users can easily find, play, and manage their multimedia contents at any place and anytime.

Bacterial grain rot by Burkholderia gluae cause severe damage in seedling and grain of rice after heading season. This seed-borne pathogen play a role as first infection agent that could be cause disease following cropping season. Until now the direct isolation of the bacteria has some trouble by interference of other bacteria existed inside seed. This study established convenient identification method as simple isolation with KB medium from seed showing symptom and using PCR identification. By this isolation method, B. glumae was isolated from 40 to 50％ in brown rice and inner hull, however, there were saprophytic bacteria and fungi outer hull. In PCR identification with Ogf4 and Ogr3 primer to these 25 isolates, the amplified products were presented in all of the collections but not in 10 saprophytic germs. The isolation rate was constant to 3 months stored seeds. This result provide a rapid and convenient isolation and identification of B. glumae.

Electrostatic Precipitators have been used widely in industry, and play an important role in environmental protection. Electrostatic Precipitators (ESP) can be operated with a high collection efficiency and low pressure drop. Pulse energization is a technique to cope with high resistivity dust, and this results in lower power consumption. In this paper, Pulse energization ESP to use subway station air clean in subway station, design and test a pulse power supply for ESP.

Passenger safety is a primary concern of railway system but, it has been urgent issue that dozens of people are killed every year when they are fallen from train platforms. In this paper, we propose a vision based monitoring system for railway station platform. The system immediately perceives dangerous factors of passengers on the platform by using image processing technology. To monitor almost entire length of the track line in the platform, we use several video cameras. Each camera conducts surveillance its own preset monitoring area whether human or dangerous object was fallen in the area. Moreover, to deal with the accident immediately, the system provides local station, central control room employees and train driver with the video information about the accident situation including alarm message. This paper introduces the system overview and detection process with experimental results. According to the results, we expect the proposed system will play a key role for establishing highly intelligent monitoring system in railway.

Game was begun to sell to multi platform rather than is sold as a title of a kinds of machine since some moment. In case of competition flag species such as PS (Play Station) or XBOX, there is 'Final Fantasy', 'Gear of War' masterpiece. However, title of game was begun to manufacture to multi platform and this is step that much games are manufactured to multi platform by selection of game developers to minimize danger by production cost rise of game. About game character development method in multi platform surrounding that this research is such game character abstract of multi platform and multi platform environment direction for multi platform through analysis and example proposal to basis data for presentation utilize wish to.

The change of shopping environment created new emerging type of shopping center after 1990's, Urban Entertainment Center(UEC) in northen America. One hand traditional shopping center was retail-centered, the other hand UEC is entertainment-centered and offers the trinity of synergy. Each components, that are retail, dining and entertainment, play a role of drawing people, extending duration of visiting and making people revisit then the synergy makes commercial profit in shopping center. As northen America many of shopping centers with complex have been built in Korea since 2000 and some projects is planning by the change of shopping environment and regenerating urban. Although the term of "UEC" is used in Korea, it seems to be added entertainment facilities to shopping center without considering on commercial strategy. This study will take a look at mix and duration of visit which ULI stresses in UEC development and comparing with those of Yongsan Station and Chyeongrangri Station which are built recently in seoul, it will get characters and situation of these UECs. Finally, the analysis is to be used as a planning data in UEC development.

A simple compost windrow-forming car and a compost tuner were developed at the aim of low cost manure management systems. The developed compost windrow- forming car is possible windrows formation at a short time. In order to be pulverized and mixed by upper and lower beaters at the windrow-forming, the condition of air and the mixing of materials to play a major role in composting is filled. This car can also utilized for a manure spreader by folding the windrow-forming cover. The developed compost turner is a type equipped with tractor rear-right side. Main specifications are 2.5m working width, overall length 3.3m and 45degrees conveyer inclination angle, 2 beaters for mixing and pulverization are equipped in front parts. Windrows of 2.5m width and 1.5m height are turned at the speed of 4.5-5.1m/min. In accordance with the above, by combining the compost windrow-forming car and the compost turner, a simple composting system for each farmer could be constructed by the low c st.

Objective is to design a high performance purification filter system of reactor coolant and seal injection system at nuclear power station. The purification filter systems play an important role in the stability of the nuclear and volume control system which consist the primary network systems of the nuclear power station. But the users of the purification filter systems frequently suffer from high maintenance cost which comes from lack of understanding of the system technology and domestic suppliers. It is time to establish a high performance domestic filter system manufacturing technology and optimum design for wide use in industrial applications.
