The pre-paid nation-wide interoperable transportation card, which an pay fee of bus, subway, train, and highway with just one card, released in June. 2014. It has started and operated from Seoul, Gyeonggi, and major local metropolitan area. In this paper, after starting of service, we evaluate conformance and interoperability of nation-wide interoperable transportation card system in real situation. Through this, we check the status of its technical operation. For this, we choose 6 region included Seoul, Gyeonggi which are serviced by different transport vendors and check recognition and billing result from field of transportation card terminal. As a result, we can reach that the major nation-wide interoperable transportation card operate normally and deliver CONFIG DF query command. It means nation-wide interoperable transportation card system which use only one card stably adapt the public transport system and it can make user's public transport use convenience higher through the extension of service area.

This study intends to research model to nation-wide Library Cooperative System in Korea and to make legal and institutional devices. For this purpose, it analyzes and investigate theories, types and model of Library Cooperation; and current status and problems in operations of major Cooperative System in all library types. The results developed new model of national wide Cooperative System on the basis of region Cooperative System.

The study is to analyze the middle school-science parts among the products of nation-wide science exhibition for eleven years recently and the results of compared to the content of science-textbooks of middle school. The number of observation in the student parts among the products of nation-wide science exhibition was the highest in all methods studied, whereas, most teachers surveyed experiments in their products. The mean Shannon's diversity index (DI) was same trend for students and teachers. There was a non-significant difference of the methods in students and teacher groups according to years and the association between students and teachers were closely connected with methods. The correlation between the content of students' products and texts of middle-school was highly positive for earth science, chemistry, and biology, whereas physics showed negative correlation.

This study intends to develop a model of nation-wide library cooperative system for Korea. It analyzes and investigates the definitions, types and models of library cooperation; and current status and problems in operations of major cooperative systems in Korea and other nations. There are some cooperative systems such as cooperative system for public libraries operated by the National Library of Korea and other systems based on their regions or library types in Korea. New model of nationwide cooperative system can improve library functions through many cooperative plans.

Although the existing X-CASH card system observes the KS standard for a transportation card system, there has been an issue for interoperability between X-CASH and other public transportation system due to the partially undefined part in the standard. This issue is followed by the inconvenience of the existing X-CASH users. If the existing X-CASH card user wants to get any other public transportations which are not interoperated with X-CASH, the user would have to buy other cards. Consequently, some users have to bring more than one card with them. In addition, it is almost impossible that the existing X-CASH system operator makes the X-CASH card available for the infrastructure built by other cards operators because their technologies are too much different. The X-CASH operator must construct its own infrastructure on the same route and it would cause an unnecessary loss of expense and labor. To solve these problems, We modified the existing X-CASH system and developed the Nation-wide Interoerable X-CASH system which lets both the existing X-CASH card and Nation-wide Interoperable X-CASH card work. This developed X-CASH system consists of the purchase SAM, the purchase terminal and the settlement. And The conformity test for it was successfully authorized. Also we, KORAIL NETWORKS, have done the test-bed on this Nation-wide interoperable X-CASH system in Gwangju for six months with Telecommunications & Clearings, the HiPlusCard Corporation. This test confirmed that the Nation-wide Interoperable X-CASH system would practically work well.

An important purpose of screening DSM(Demand Side Management) programs is to determine which programs or technologies seem to be moot worthy of further development, given the characteristics of the particular utility system. Complication found in screening DSM technologies is the consideration of costs and benefits from several perspectives : the utility, society, participants, free riders and nonparticipants. In this paper, a nation-wide DSM screening model is presented using a rigorous mathematical formulation on the financial basis and the concept of marginal coots considering all affected parties inside the nation is fully exploited.

Each office developped GIS for their own purpose recantly. But many cases, establ ished in some local government off ices, were found not to perform properly. The main problem is to integrate different offices' systems. Also. accurate nation-wide digital basemap database does not exist in Korea. To solve these problems, the suggestions are following: $\circled1$ develop the nation¬wide digital basemap database to increase the effectiveness of GIS, $\circled2$ make the database with standardized format, $\circled3$ educate and train people to be spcialist, $\circled4$ make laws and regulations to share and to integrate database.

The existing K-CASH system doesn't allow compatible between different regions, different public transportations and the technologies made by different operators. If a K-cash user wants to use public transportation charged not by K-CASH but other operator, then he or she would have to get other type of card available for that transportation. Also, the incompatibility of the existing K-CASH might cause unnecessary expense because similar systems would have to be doubly constructed if the K-CASH operator would like to install the K-CASH system on the same infra as the other operators already did. As a result, a system which allows people to use just one card for their convenience regardless of regions, types of transportation and operators has been strongly demanded. In this paper, we developed Nation-wide Interoperable K-Cash system, Nation-wide Interoperable K-CASH Card, Purchase terminal, Purchase SAM and Settlement system that were updated from the existing K-CASH system. And we performed a conformity test to confirm performance. Also Korea Financial Telecommunications & Clearings and the KORAIL NETWARKS and the HiPlusCard joined for the testbed in Gwangju for 6 months. This result of testbed finally proved that the Nation-wide Interoperable K-CASH system is completely compatible.

In this paper, we describe the result of the test-bed on Nation-wide Interoperable Transportation System connected with Interoperable Traffic Information Collection System, which was developed by Korea Financial Telecommunications & Clearings, KOREAIL NETWORKS, HiPlusCard and Samsung SDS. we constructed Nation-wide Interoperable Transportation System on 4 downtown bus routes, 20 stations on line 1 subway, 2 stations of a train and 2 sections of the Honam highway in Gwangju and Interoperable Traffic Information Collection System in Seoul University IC Card Center. So we operated that by 480 Several staff were given a test card and asked to try it for about 6 months. This test-bed is for demonstrates the accuracy, safety and credibility of the Nation-wide Interoperability standard technology and it can be applied to all of transportation practically. When the staffs contact the card to Purchase terminal, the card performs transaction with Purchase SAM in the terminal, then transactions ara used to calculate in Settlement system and Interoperable Traffic Information Collection System. Through the test-bed, we examined this process and found unexpected problems happening during the test operation and have successfully solved them. In addition, the results of the test-bed let us know what additional improvement might be required for System. The successful run of the test-bed was verified by an evaluation of the test-bed staff and a public survey.

This study surveys science information resources and science information resource services institutions existing in the field of scientific research to analyse their strengths and weaknesses, which provide theoretical foundation of planning an effective and efficient nation-wide science information transfer system for Korea. This study also suggests right directions of developing a centralised system of science information for Korea.
