In the spiral wound module of the pressure-retarded osmosis (PRO) system for the salinity gradient power generation, effects of the inlet pressure differences between feed-channel and draw-channel were studied. Fluxes of water and solute through membrane and power were estimated. The water flux through membrane decreased along the x-direction and increased along the y-direction with the increase of inlet pressure differences between two channels. On the other hand, the solute flux through membrane showed the opposite trend. The concentration of flow in the feed-channel increased a lot along the y-direction and that in the draw-channel decreased along the x-direction. In our system, for the inlet pressure differences of 1~11 atm, the flow rate in the feed-channel decreased about 8~13% and that in the draw-channel increased by the same amount. The power density increased and then decreased with the increasing inlet pressure difference.

As a term 'Media Big Bang' will appear, the media is extending explosively. But actually it is appearing the paradoxical phenomenon which journalism meets a crisis. If the purpose of journalism is 'to provide people with the information they need to be free and self-governing', the crisis of Journalism directly brings about the result which damages audience welfare. Consequently the preceding task which defends the public good of journalism is accurately to get at the root of the substance which brings about the crisis of Journalism. In this paper, the principle and basic ethics of Journalism was theorized on the concept of truth and fairness, how about Korean journalism was answered to the standard is analyzed. With the result it was confirmed Korean journalism does not defend even truth and fairness about important agenda to be solved today. It was recognizes the substance which brings about the crisis of Journalism is 'the crisis of basic ethics', and was presented a an alternative proposal. It was introduced the research of 'Committee of Concerned Journalists' in the United States, and proposed the effort which is saved journalism with organic combination of Korean academic world and journalist' group.

In september 2004, a new pilot certificate scheme referred to as Sport Pilot Certificate was declared official and standardized in the US. The designation of Light-sport aircraft and the details of the relevant pilot certificate policy was announced out of the perception that a new regulation is required to be applied whereby the limitations on the manufacturing process enhancements and current aviation rules are considered the triggering factors. US Federal Aviation Regulation retains a comprehensive range of airworthiness certificates and aircrafts are managed systematically in accordance with FAR 21, 103. The airworthiness are further segregated into sub categories, which allows differentiated management. Korean Aviation Law classify aircraft into five different categories and powered air vehicle that weighs more than 150kg(19liters fuel capacity) for one seat, 225kg for two seats(38liters fuel capacity) while the systems that fall under a specific mass threshold level are known as ultralight vehicle. The research discusses the policy of the sport pilot certificate and the light-sport aircraft ratings announced official by the Federal Aviation Administration in an intuitive fashion with the analysis of the operations providing the evidence as to the viability of adopting the policy in local grounds. Based on the findings, the report discusses the case for introducing the light-sport aircraft and make recommendation on a strategy of applying the policy in Korea with respect to the pilot certificates, safety agenda, and the written test for the pilot certificate, and operating efficiency.

In hosting outdoor activities and school trips, safety issues are gaining serious attention lately. In addition to Sewol ferry tragedy and an incident at Kyungjoo Mauna Resort, there have been grown problems related to this crucial factor. This research analyzes negligent accidents occurred from domestic and foreign schools and aims to provide effective safety education and policy through comparative analysis between domestic and foreign cases. We mainly relied on documents such as newspapers, internet articles and legal papers to investigate cases and cooperated with relevant government departments for collecting references and setting agenda for safety supervision. The analysis on both domestic and foreign cases revealed that students abroad receive opportunities for first-hand experience regarding safety and systematic education, as safety maintenance is prioritized. Based on this culture, safety education should be habituated domestically, while participatory safety programs that students can actively involve must also be devised. Moreover, through preparation of entertaining contents such as SNS game programs, skits and activities employing multiple facilities and vehicles at school safety education, we must induce students to actively participate in the program with interests.

Up to present science and technology (S&T) policy in Korea has focused on producing academic papers and patents through the increase of investment on research and development (R&D). However, as the role of science and technology on boosting national economy has been emphasized and the current government has established 'creative economy' as a main policy agenda, 'technology commercialization' has been moving onto the center of S&T policy. Technology commercialization policy encourages R&D outcomes of public R&D institutions to be utilized in private firms for their new business development, and this concept is in line with out-bound open innovation, in the sense that it involves the flow of technological knowledge from public R&D institutions to private firms. Based on this understanding, this paper analyses government technology commercialization programs and attempts to suggest policy implications. The results suggest that future technology commercialization policy (1) be specialized in a way of reflecting the characteristics of each government ministry, (2) strongly support technology licensing-out, (3) strengthen the linkage between each programs, and (4) nurture expert groups, such as accelerators who can help and foster technology start-ups.

The importantce of a development of competitiveness in domestic construction industry is growing as some of domestic construction markets is scheduled to open to foreign competing firms with higher level of construction technology and management. A national level of competitiveness in domestic construction industry and firms are partially, but significantly, affected by a technology level and a characteristics of production pattern. The purpose of the study is mainly to analyze and identify a technology level, production pattern and a development stage of R&D activities of domestic construction industry and firms. Based on these findings the study draws on a concluding remarks and derives technology policy implications. Results of analysis in the study impliy that (1) competitiveness of domestic construction firms(industry) in terms of technology level is relatively weak as compare to that of advanced foreign competing firms, (2) degrees of substitution of capital for labor are seemed to be relatively high, (3) R&D (investment) activities of domestic construction firms are generally spread out in forms of import, adjustment and betterment, and (4) only a small number of big domestic construction firms are seemed to afford to R&D investment for research facilities and equipments, but not enough for higher level of R&D man-power. The study suggests that technology policy for construction industry should be based on a fundamental policy directions. For example the increase in size and heightened quality level of R&D man-power should be placed in a top priority in policy agenda. Sound and specific policy items should be developed for planning and design, and maintenace and inspection technology in order to lead domestic industry to compete with foreign firms with full strength.
