Motivated by the open access movement, research institutions are building Institutional repositories for a nation-wide knowledge distribution infrastructure. IKIS (Institute Knowledge Inventory System) was proposed to integrate materials produced by government-sponsored 23 institutions of the economic, social and human fields, to contribute for policy-making in national agenda and to proffer services to a people. As IKIS project goes on. the project turns out to be slower than planned especially In terms of building up content and improving system functions. This study aims to investigate the methods for promoting the system in terms of management and system developments using multiple research methods such as surveys and interviews. Five issues including budgets and marketing are proposed for the management strategies, whereas three ones Including content and system performance improvements are suggested for the system development. The study results can be utilized as guidelines for managing university and school repositories as well as IKIS.

Currently, every person possesses a smart phone due to the development of the IT industry. However, crosswalk pedestrian accidents have been sharply increasing due to smart phone use. If a traffic light can recognize smart phones when a smart-phone user approaches and arrives at a given sign, many accidents could be reduced by using beacon signals. Before the era of smart phones, the accident rate involving cell phone use was relatively low. Nevertheless, when considering the development of IT equipment that produces a threat to human life, government cannot regulate smart phone use outside. The purpose of this paper is to indirectly warn a smart phone user in order to reduce the accident rates.

Research is one of main roles of university and its importance has been emphasized gradually since a few decades ago. Yet, the objective and concrete criterion lot the definition of the research university is not available in Korea, Accordingly, the role of the research university library is not established as a key system for research university. In this study the criterion for the United States research university is applied to domestic universities, thereby current status of research universities and their libraries between the United States and Korea is analyzed comparatively. Fundamental data including budget, employees and information resources for pursuing high research competitiveness necessary for the research university library are provided based on comparative analysis of 98 research university libraries in the United States and 38 domestic research university libraries. Correlation analysis data between library investment and research Publication are also provided. Finally this study can be used, hopefully, as a milestone for the establishing strategy of domestic research university libraries.

As UCI (Universal Content Identifier) identification system becomes a national standard for content distribution, many digital contents are distributed through UCI identification system. However, problems associated with copyright infringement and copyright contracts occur due to lack of copyright information. ICN (Integrated Copyright Number), a code system developed for copyright management, includes copyright-related information for the purposes of usage settlement and accounting, illegal usage monitoring, and content filtering. ICN, however, has no information about distribution and content properties. Therefore, the linkage and integration between UCI and ICN can be a basis for the transparent and effective distribution of digital contents. In this paper, we propose a model for linking and integrating UCI and ICN, developing the efficiency in the value chain of each identified system by analyzing political factors and key technical elements between the two identification systems.

In recent years, the maker culture has realized the concept of 'making' itself through the latest technology of high technology. It is rapidly spreading as a maker's movement by sharing the production methods and information of individuals through the Internet. Countries that are leading the makers' movement expect the maker's movement to be the driving force for new value creation and economic growth from the point of view of things and the Internet. We are developing various types of open IoT platforms that can register various Internet devices and services manufactured and developed through DIY and realize interoperable services. Typical open IoT platforms require specialized API analysis capabilities and difficult access to general users due to difficult platform registration conditions and procedures. In this paper, we try to construct an open IoT platform that can be operated as a real service by creating a simple Internet application device and service application from a general manufacturer's point of view.

Energy consumption in buildings is close to 40% of the total national energy consumption in developed countries such as US and Japan, and Korea accounts for 24% of total energy consumption. In buildings, HVAC can't freely control the cooling flow rate according to the required calorie, so energy is not used efficiently. Therefore, by using the energy saving valve, the flow rate can be controlled by the required amount of heat and the energy can be saved. In this paper, we define basic conditions and develop control and monitoring boards for building energy saving valves based on PIC processor with low power and high cost-effectiveness. The designed board displays and transmits in real time information about two temperature values, flow values and calculated calories for temperature difference measurement. The developed board will be useful for real - time monitoring of the state of the valve in the future and development of the valve for the offshore.

Identifying Emerging Technology Trends is crucial for decision makers of nations and organizations in order to use limited resources, such as time, money, etc., efficiently. Many researchers have proposed emerging trend detection systems based on a popularity analysis of the document, but this still needs to be improved. In this paper, an emerging trend detection classifier is proposed which uses both academic and industrial data, SCOPUS and PATSTAT. Unlike most pre-vious research, our emerging technology trend classifi-er utilizes supervised, semi-automatic, machine learning techniques to improve the precision of the results. In addition, the citation information from among the SCOPUS data is analyzed to identify the early signals of emerging technology trends.

The cadastral surveying is essential for the effective management of a country, the D/B building of NGIS. Many of GPS applications require a positioning accuracy of several centimeters for rover in real-times. But, to achieve higher positioning accuracies in real-time, the double differencing technique should be implemented using carrier phase data. Corrected observations at the reference station can be transmitted and used to form double difference observations at the rover using a data link. In this study, the area accuracy of cadastral survey using the RTK GPS will be assessed, and will produce area of parcel of land. As the result of comparison among area by TS, planer surveying and RTK GPS. parcels-register for site is analyzed by this data. The results show that mean error of area calculated min. $2.42m^{2}{\sim}\;max.\;13.69m^{2}$ and RMSE calculated min. $0.00329\;{\sim}\;max.\;0.01846$.

The development of communication method for a variety of intelligent automobiles are delivering comfortable and safe information. However the development of such communication method must also think about security. Even the update of navigation to be used for intelligent automobiles uses the wireless updating methods but the updating methods currently being used has no reliable security measures. The navigation communications used in the intelligent automobiles are being provided with TTI(Traffic and Travel Information) service using a variety of methods by the countries. In the case of Korea, most are based on T-DMB using the TPEG method for transmitting the information. By identifying the characteristics on the navigation wireless update, a security solution is proposed for delivering the reliable update information after creating the attack scenario.
