As our society leads into information age, it becomes necessary to build a new national science & technology information system responded to new social technological change. Therefore, It is needed a picture of the new economic structure to introduce a new system, but our part of science & technology information service have not taken into account of it. This paper gives the national R&D electronic information service system of science & technology in this new change a guide to the coming structure, thus allowing it to better define and position its offerings in the context of one another. The premise of this paper is that new role of it will be based on the structure of new national science & technology information system In this research results, information society of the future is going to the direction of maximizing the economies of extent and connection. The intent of Science & Technology Integrated Information System is hold the information in common, to possess accumulation benefit of the information. In this system, science & technology information fulfill its function of a R&D part in national management system, therefore cooperation among enterprise, school and research institution is easily made through the process into more enhancing the total competition of national science & technology.

Survivability is a necessary property of network system in disturbed environment. Recovery ability is a key actor of survivability. This paper concludes network survivability into a novel composite metric, i.e. Network Recovery Degree (NRD). In order to measure this metric in quantity, a concept of Source-Destination Pair (SD Pair), is created to abstract end-to-end activity based on end nodes in network, and the quality of SD Pair is also used to describe network performance, such as connectivity, quality of service, link degree, and so on. After that, a Survivability Test method in large scale Network based on SD pairs, called STNSD, is provided. How to select SD Pairs effectively in large scale network is also provided. We set up simulation environment to validate the test method in a severe destroy scenario and evaluate the method scalability in different large scale network scenarios. Experiment and analysis shows that the metric NRD correctly reflects the effort of different survivability strategy, and the proposed test method STNSD has good scalability and can be used to test and evaluate quantitative survivability in large scale network.

The use of national R&D reports becomes a difficult task due to the different level of service being provided and the different way used for its construction by the institute in management. One-stop service of its contents is impossible and there is a lack of specialized service such as a system to satisfy the various needs of the researchers. This study analyzes the laws related to the national R&D reports and the evaluation system of the R&D outputs for the design and construction of the DB and system for the management of the national R&D reports. We also perform an analysis of the economic effect of the system.

The oversea export of agricultural-product about item and quantity has not increased recently; especially the fresh-product has a tough issue because of period of production, price large fluctuations, customs clearance, quarantine, and uncertainty about actual locality, we need the information based construction to exchange information quickly about whole range of export and to focus capacity of participation subject for increasing the export. In this study we design the agricultural-product transaction information system based on crowdsourcing to transact the agricultural-product and the information of influencing benefit directly, and the information offering about export-procedure from participation of customs clearance, finance, distribution, buyer, and producer's guild, etc. We expect the producer's guild about agriculture that has not participate the trade to be able to export the agricultural-product and the stabilization of price to transact the product of collapsed or boomed through the agricultural-product information system based on crowdsourcing.

For national industrial development in the Fourth Industrial Revolution, it is necessary to provide researchers with appropriate job information. This can be achieved by interconnecting the National Science and Technology Standard Classification System used for management of research activity with the Korean Employment Classification of Occupations used for job information management. In the present study, an automatic linkage model of classification systems is introduced based on a pre-trained language model for interconnecting science and technology information with job information. We propose for the first time an automatic model for linkage of classification systems. Our model effectively maps similar classes between the National Science & Technology Standard Classification System and Korean Employment Classification of Occupations. Moreover, the model increases interconnection performance by considering hierarchical features of classification systems. Experimental results show that precision and recall of the proposed model are about 0.82 and 0.84, respectively.

There are the national science and technology standard classification system used in Korea, the classification according to the standard classification system for educational organization units, and the Korean standard education classification by the National Statistical Office. It is not suitable for calculation or evaluation, and classification is still mixed depending on the purpose of use. Therefore, in this study, the current status of academic standard classification, issues related to the standard classification system such as research foundation associations and research institutes, and issues related to the academic standard classification through the analysis of existing prior research issues, etc. As a result of the research, first, it is necessary to maintain and strengthen the linkage of the academic classification system, such as maintaining the linkage between the relevant departmental classification systems and strengthening the linkage with the relevant classification system, as a result of analysis of major issues in the academic standard classification system, and the systematic improvement cycle of the revision process and management system and settings are required.

The national management and retrieval service of the national scholar Content DB are very important. High quality content can improve the user's utilization and satisfaction and be a strong base for both the citation index creation and the calculation of journal impact factors. Therefore, the system is necessary to check data quality effectively. We have closely studied and developed a webbased data quality checking system that will support anything from raw digital data to its automatic validation as well as hands-on validation, all of which will be discussed in this paper.

National R&D programs are managed and operated by institutes under different ministries. The R&D information created through these programs are designed and constructed heterogeneously both semantically and structurally. Therefore, integrated collection, analysis and application of the information through the interoperability of information at the national level becomes nearly impossible, and redundant production and operation of R&D information becomes a general problem. The Office of Science and Technology Innovation has started the construction of the National Science and Technology Information System(NTIS), which is based on the interoperability and sharing of R&D information, to resolve these issues. In this paper, we propose a method to construct a system for sharing national R&D information held by different ministries while minimizing the effect on the autonomy of the institutes involved.
