In driving at evening or night, we are not able to recognize the speed bump and so stop suddenly. It could result in accidents. And also, we have a restriction of street light installation in farm road because it could be harmful to the crops and driver could not recognize the walking people. It needs to develop the speed bump with light and streetlight to be non harmful to the crops. So, we develop both the speed bump and streetlight with LED which could be non harmful to the crops and be increased recognition of walking people in farm road. For LED lighting power, we use the solar cells, and piezoelectric elements. It has automatic on/off according to power saving rates without illumination sensor. Minimization of circuit elements and design of minimum resisters and low power LED was used for power saving in assuring 3-days.

University-industry cooperation is indispensable for a short-term problem solving, as well as sustainable growth in the economy of the Republic of Korea. In order to embody and implement that, the government has run a variety of financial assistance programs and policies for the promotion of the cooperation for the last 10 years, and Korea Sanhak Foundation has made progress in academic and research development support, creative personnel training and scholarships, International Support and other projects. In this paper, window-type university-industry convergence and practices, and analyzing the best practices of national and international IT-based fusion technology, corporate cooperation were established to support measures taken in conjunction type and model of the university. Industry utilizing the latest IT technology based on this model, academia, proposed a collaboration system between workers building measures.

Due to the development and market expansion of image analysis and recognition technology, video security such as CCTV cameras and digital storage devices, are required for real-time monitoring systems and intelligent video security systems. This includes the development of more advanced technologies. A rotatable PTZ camera, in a CCTV camera system, has a zoom function so you can acquire a precise picture. However it can cause blind spots, and can not monitor two or more moving objects at the same time. This study concerns, the intelligent tracking of multiple moving objects, CCTV systems, and methods of video surveillance. An intelligent video surveillance system is proposed. It can accurately shoot broad areas and track multiple objects at the same time, much more effectively than using one fixed camera for an entire area or two or more PTZ cameras.

This study analyzes the concentration ratios (CR) and the shift effect in the system of Korean container ports that concern the export and import of container cargos, especially from/to 5 overseas origin/destination (O/D) regions, using the Hirshmann-Herfindahl Index (HHI) and the Shift-Share Method. The results shows that the CR has decreased during the last 20 years, from 0.86 to 0.44, mainly because cargos from/to the Far-East/South-East Asian regions have become more dispersed to several domestic container ports, especially from the Port of Busan. This study also indicates that there has been little change in the CR for all cargos, like the value of -0.3%, in the last 5 years. However the change in CRs for the cargos from/to the North America and Europe is positive, with the value of 7.6% and 6.6%, respectively. It can be inferred that the future development of medium- and small-sized container ports in Korea is not very likely. The study also suggests that the CR and the shift effect of the Korean container ports for the cargos by the domestic O/D regions should be analyzed in the future to suggest policy implications in great detail.

In the 1990s, when the viewpoint that an ecosystem is a single network within a specific region was adopted, the preservation and management of natural ecosystems was proposed. With regard to Northeast Asia, the expansion of trans-boundary pollution due to rapid development and the swift destruction of the natural environment emphasize the necessity for environmental cooperation. The Northeast Asia region made up of South Korea, North Korea, three northeastern prefectures in China, the Russian far-east, and parts of Mongolia were selected to be analyzed for an ecological network. The significance of this study lies in the development of a methodology for building a Northeast Asian ecological network through the use of satellite images. Regarding the methods of analysis, stable habitats for four priority species were selected to be performed using overlay analysis. The result of the analysis of the ecological networks in the whole Northeast Asia region showed that there were key areas partly dispersed in the Korean Peninsula, but whether the key areas would be maintained in the long term is unknown. As for China, key areas were concentrated in the border areas around the Tumen River and in parts of the three northeastern prefectures. Russia had wide-ranging areas that could function as stable habitats for most species. As a result of the actual conditions of the ecological networks, most of the Northeast Asia region, including the Korean Peninsula, was in poor condition, requiring appropriate measures and their operation as soon as possible. Also, it was revealed that further investigation and research was necessary for border areas that were identified to be key areas.

Recent, development of wireless communication devices are rapidly and these device being deployed to the user very fast. By this results, a wired network device and the new device such as wireless devices incorporate. Then a demand of new mesh network is rapidly growing. In this wired/wireless integrated network environment, the network is configured automatically, and a user or wireless communication devices must be provided for authentication services. But, these services do not in the real world. Therefore, in this paper, we propose that wired/wireless integrated network environment to automatically configure the network using OpenFlow and the authentication system using Kerberos method. Our proposed system to be able to provide authentication services, confidentiality, integrity services for user or wired/wireless communication devices. And it can be prvented as well to man-in-the-middle attacks.

If a digital signage system is operated in PC mounted in the Window OS then the implementing price is very high. For resolving this problem, we used the Smartphone mounted in ARM Cortex family of multi-core processor-based mobile platform. We developed a low-power low-cost digital signage system and a remote convergence content management program based on web server. This convergence system manages advertising content to a remote control device anywhere using remote control technology. This system is one integrated system with display and is a low-power consumed and is developed in very efficient hardware interface. And condition sensors(intensity of illumination, temperature, weather, GPS etc) is equipped in the developed system. Automatic contents builder and Context-aware SMIL module is also implemented in the convergence system. We achieved over 50% power savings comparing with conventional Window OS system and 16 points multi-touch in our system.

This study aims to develop the scale for business effectiveness targeting microcredit users. For this, based on domestic preceding researchers empirically handling the microcredit and also focus group interviews with users and specialists, total 30 preliminary questions were composed. After that, conducting the exploratory factor analysis targeting 127 finally collected surveys, in the results of analysis, the scale validity of three factors and 24 questions was verified. Also, considering the goodness-of-fit of model through the confirmatory factor analysis, the effectiveness scale of microcredit business was determined. The concrete factors included 5 questions of the store operation, 3 questions of business start-up satisfaction, and 16 questions of management competency. Lastly, based on the effectiveness scale of business developed by this study, the research direction and the practical development direction of microcredit was suggested.
