The food R&D operating system needs to be changed according to the changes in the food industry as well as the domestic and overseas environments. In this aspect, a future-oriented food R&D operating strategy linked with the governmental policy are proposed to foster the promising food industry. The strategic R&D approaches are summarized on the basis of global mega-trends and food industry trend analysis, and current R&D status and issues are also reviewed to set the R&D operating direction for future food industry. To advance the R&D operating system of the food industry, some practical suggestions are given as follows: strengthening the research planning system for efficient R&D program operation, enhancing the role assignment and collaboration among the R&D organizations, reinforcing the support system tailored to industrial sites and securing the future technology bases as well as resolving present issues, and linking R&D programs with policies and improving the food R&D management system.

SpaceX shows various strategies such as constructing various payload portfolio through the reuse of Falcon 9 and Falcon Heavy, constructing the launch vehicles using one type of engine, the transition from kerosene engine to methane engine, and the use of 3D printing. In this study, launch vehicle proposals that can cover a variety of payloads and trajectories from KOMPSAT to GEO-KOMPSAT were constructed, and ten launch vehicles using kerosene gas generator cycle engine, kerosene staged-combustion cycle engine, and methane staged-combustion cycle engine were reviewed. Of the ten launch vehicles, the reusable launch vehicle using a 35-ton methane engine was rated as the best in terms of development potential.

The Future Army in 2050 should prepare for various future threats and effectively utilize its superintelligence and hyper-connected weapons systems to develop ways of fighting new concepts to dominate multi-regional battlefields and achieve victory. First, the establishment of active and offensive military strategies based on ability. Second, the battle of central strike for enemy combat will paralysis. Third, the battle of simultaneous integrated mosaic using multidisciplinary areas. Fourth, cyber warfare based on artificial intelligence that transcends time and space. Fifth, Combined Platform War. After all, future wars will be won or lost by invisible wars on cyber space.

MSIP(Ministry of Science, ICT and Future Plaaning) established the 'space technology commercialization plan' at 2012. According to this plan, MSIP and KARI(Korea Aerospace Research Institute) are nuturing space-related venture companies so that those companies are increasing from 2013. In addition, MSIP and KARI held space-related idea festivals last two years, and will run start-up program (STAR-Exploration) this year.

This paper discusses the strategies for the future qf the Hong Kong Port and Buasn Port. We assess whether they prepare the ports for the position of being the logistics hub, and as such could assist the ports to maintain their position in the world's container port. We reviewed both the current situation qf the Hong Kong Port and the strategy of the port for the future (Master Plan 2020) to keep the status of logistics hub. With the case study on the Port of Hong Kong, this study attempts to examine what the strategic planning is needed for the Busan Port. We debate the Port of Busan could be seen as a logistics chain for the future. In our discussion, the strategic planning on "Port Vision 2020" for Port of Busan does not address the issues regarding this part, nor does it make any recommendations in terms of the requirement of the logistics private sector.

Given the continued climate change and global warming, various technologies for greenhouse gas reduction were discussed worldwide as all 195 countries participated in the Paris Agreement on the reduction of greenhouse gases. The agreement was adopted at the 21st Conference of Parties to the UNFCCC (COP21), which was held in Paris, France, in December 2015, and it revealed that reducing CO₂ is the most efficient method of greenhouse gas reduction. Accordingly, carbon capture/utilization/storage (CCUS) technology has been noted as a means of making practical contributions to CO₂ reduction, and research and development (R&D) activities in many countries are active in the field of CCUS technology. Therefore, this study aims to provide a basis for CCUS R&D and strategic support measures by analyzing patent trends in technologies related to CCUS. The patent analysis collected a total of 10,137 patents in the United States, Korea, Japan, Europe, and China; the number of patents in the United States was the highest according to patent analysis by country. According to an analysis by technology, capture-related technology was high at 60%, but given the recent increase in technology related to utilization, technology demonstration, R&D, and policy support should be continued.

This study has analyzed the scale, location, resource potential and feasibility of offshore wind farm scientifically and systematically based on the national wind map and GIS (Geographic Information System). For long-term wind power development, this study pursues siting strategy building, selection of target area and deciding development priority as well as the presenting a basis for assessment that are necessary for policy decision making by making theme layers under GIS environment. According to the analysis after organizing technological development by stages, even if only the most suitable sites are developed among the area of offshore wind farm candidates that can be developed under the current technological standard, it has been evaluated as being able to develop about 3 times of the wind power dissemination target until 2012. It is expected that about 5% of territorial water area can be developed in a short-term future while the southern offshore area possessing relatively favorable wind resource than the western offshore has been identified as the most feasible site. While about 23% of territorial water area has been classified as potential area for offshore wind farm development in a long-term future, even Jeju Island and offshore of Ulsan possessing excellent wind resource have been analyzed as feasible sites. The feasibility assessment of offshore wind farm development established by this study is expected to assist national strategy building for accomplishing the wind power dissemination target.

Numerous proposals for extending the relational data model as well as conceptual and object-oriented data models have been suggested. However, there has been relatively less research in the area of defining segmented storage structure and data migration strategies for temporal data. This paper presents the segmented storage structure in order to increment search performance and the two data migration strategies for segmented storage structure. this paper presents the two data migration strategies : the migration strategy by Time granularity, the migration strategy by LST-GET. In the migration strategy by Time Granularity, the dividing time point to assign the entity versions to the past segment, the current segment, and future segment is defined and the searching and moving process for data validity at a granularity level are described. In the migration strategy by LST-GET, we describe the process how to compute the value of dividing criterion. searching and moving processes are described for migration on the future segment and the current segment and entity versions 새 assign on each segment are defined. We simulate the search performance of the segmented storage structure in order to compare it with conventional storage structure in relational database system. And extensive simulation studies are performed in order to compare the search performance of the migration strategies with the segmented storage structure.
