This paper suggests the significant strategies and their priority to deal with space transportation market trends. First, market trends related with technical improvement and change in demand are analyzed by the literature research. The three key trends are obtained: 'Increasing Demand of High-Performance Launch Vehicles', 'Rising of Low-Price Launch Vehicles', and 'Rising of Dual/Multi-Launch'. And then, strategies for developing the launch vehicle industry in Korea are selected from several studies about commercialization of Korean launch vehicle. The strategies are evaluated by the experts through pairwise comparison matrix and the criteria for this process is how significantly does the strategy effect on the launch vehicle industry through market assessment. As a result, reliable order of priority among the strategies are obtained. Under the three key trends, strategy to enhance reliability is most important. And, strategy to have price competitiveness has secondary priority to deal with 'Rising of Low-Price Launch Vehicles' trend and 'Rising of Dual/Multi-Launch' trend. On the contrary, strategy of government's support is secondary under 'Increasing Demand of High-Performance Launch Vehicles' trend.

Background: The risk observatory (RO) of the German Social Accident Insurance (DGUV) provides strategic support to the German Social Accident Insurance Institutions (GSAII) in proactive prevention. It does so by identifying future challenges and opportunities for occupational safety and health (OSH) resulting from new trends and developments that affect employees as well as children in elementary education, pupils, and students. Methods: The core of the RO is an online survey that relies on a pool of new trends and developments identified via internet and literature research. 865 prevention experts of the GSAII and the DGUV participated in the survey. They rated trends and developments regarding their sector-specific risks and opportunities for OSH in the 5 years to come. Results: Sector-specific and over-all results show that besides well-known OSH risks such as musculoskeletal stress and noise, developments relevant for OSH come to the fore that do not have their origin in work itself, but are strongly influenced by political, social, economic, environmental, or technical developments that accident insurance can only peripherally influence. Shortage of skilled staff was identified as a threat to OSH in almost all sectors. Conclusions: Prevention must find ways to address repercussions of such OSH risks. Cooperation and political awareness are therefore gaining in importance. Also, implementing a prevention culture in society and strengthening individuals' health and safety literacy, e.g., by target-group-specific communication and sensitization, as well as early safety and health education, help to counteract those OSH risks.

Objectives : This study analyzed the managerial efficiency of hospitals and identified the productivity trends for three years. Methods : Data were collected from 44 tertiary hospitals and 32 university hospitals from 2009 to 2011. Efficiency scores and productivity trends were evaluated with the DEA (Data Envelopment Analysis) method. The input variables were the numbers of beds, doctors, nurses, and health personnel, and the medical costs. The output variables were the numbers of outpatients, and inpatients, and the medical revenues. Along with the traditional input-oriented DEA analysis, the Malmquist Productivity Index(MPI) was calculated. Results : First, the mean values of the study variables showed gradual increases in all the variables for all the study years. Second, technical efficiency scores varied depending on the study year. Third, MPI decreased from 2009 to 2010 (MPI=0.986), and then increased from 2010 to 2011(MPI=1.011). The contributions of the Efficiency Change Index and Technical Change Index on the MPI varied depending on the study year. Conclusions : This study provides information to hospital managers about changes in hospital performances. External environments had more influence on hospital performances, and hospital managers will need to manage these influences from factors surrounding the hospitals.

Radio navigation systems are already used as important national infrastructures in various fields such as air traffic, land transportation, geodetic survey, broadcasting communication and national defense, and are used in various industries. Since these systems are fusion of various technologies, it takes much time and cost in the development stage. In the early stages of development of the system, developed countries are establishing a national mid-term plan that meets international compatibility and standards. Korea did not develop the system due to the lack of national mid- and long-term plan, and it is not contributing effectively to industries. This paper analyzes the technical principles and technology trend of radio navigation system in the aviation sector to establish mid - and long - term plan. Based on the analyzed technology trends, the future prospect of technological development of the domestic navigation system and the development of related industries will be presented.

In this paper, we collected the articles related to artificial intelligence among SCI(E) journals published by Korean authors in 'Web of Science' and conducted frequency analysis and keyword network analysis. As a result of the analysis, the artificial intelligence thesis showed an average growth of about 10% per year, but the relative ratio decreased. As time went on, we could confirm that there is a lot of practical and applied research in artificial intelligence research. Unlike the US 'National Strategy for Artificial Intelligence Research and Development,' the field of research in Korea was focused on local and technical aspects. Therefore, Korea should go beyond the theoretical and technical iterations of artificial intelligence, and research should be carried out to present a comprehensive future direction.
