Most of satellite program process consists of mission analysis, thermal, structure, electronics design, and operation, etc. Each step has several steps like design phase, development phase, and verification phase, etc. As to do this kind of process, very high costs and much time are required, further high risk is included. So for solving those difficulties, satellite developers have designed and used satellite simulator system. In early stage of satellite development, simulator system was just used for a fragment of development and verification, so it could not give enough advantage on satellite development. In order to get high advantage on satellite development, full system level simulators which can be used for several steps for development and verification are evolved. So This paper introduces the trend of simulation systems for satellite development and verification used by several satellite developers.

Research collaboration between industry and universities is high on many policy agenda's nowadays, especially with regard to science-based technological innovation. Nonetheless, there have been few attempts at examining large-scale systematic and quantitative data on the nature and extent of university-industry collaborations. The objective of this paper is to explore the patterns and trends of research collaborations between universities and companies for scientific knowledge production in the seven science-based technologies. This paper uses co-authored articles published in major scientific journals in the world as an indicator of collaborative scientific research between universities, companies and governmental research institutes. The tens of thousands of co-authorship papers in the northeast region in the US over the years 2006 to 2010 were analyzed for collaboration patterns and their spatial characteristics. This paper finds that there were increases both in the proportions of multiple authored, particularly five or more, papers, and in the volume of international collaborations. By examining a type of collaborations between different institutions, research collaboration between universities and companies in this region is relatively high share at national level. This suggests that the national or even international scale seems more appropriate for innovation policies.

While dramatic shifts in the media environment underscore the emerging importance of structural approaches in media studies. political economists in Korea have failed to meet such demands. It is particularly noteworthy that their most serious weakness lies in economic theories. This paper aims to examine major problems in political economic approaches in Korea and suggest some research agenda and directions for the future. Above all, political economists need to scrutinize and elaborate both microscopic and macroscopic frameworks. On the microscopic level, they may learn tremendous implications from the "audience-commodity" thesis and recent debates on "information goods" among Korean economists. For the more macroscopic part, it is urgently needed to delve into mid-level issues that may illuminate specific ways the media capital operates: trends in the accumulation of capital, the influence of technological innovation, changes in the labor process, and the relations among production, circulation and consumption sectors.

Currently, the previous studies on the concept, configuration, and system regarding spacial information policies show the little progress. However, these studies only propose the basic structure system in terms of a policy theory, seeking and suggesting the basic concept to establish spacial information policies. In the shift of a new paradigm from a PC-based paradigm that began in the mid-2000s to the current smart society based on mobile devises, such as smart phones, this study thus reviewed the strategic direction of the propulsion to establish the desired future strategy for the spatial technology policy with spatial information system that can influence the future national competitiveness of Korea. The results of this study is expected to be used to analyze a variety of issues and technological changes on geospatial intelligence at the global level and to support the establishment of a road-map for policies and research & development on domestic geospatial information.

Thermal vacuum test should be carried out to verify the performance of the S/C on the ground under the simulated space environment. KARI already completed the construction of a Large Thermal Vacuum Chamber(LTVC) with 8 m of diameter and 10 m of length dimension. LTVC is for the purpose of performing the orbital environment test for large Space Craft(S/C). Inside LTVC, S/C is much smaller than LTVC. For the function test of S/C during the thermal vacuum test, the S/C has to be connected to Electrical Ground Support Equipment(EGSE) which includes several cable and RF wave guide inside LTVC. Also, MLI should be installed on S/C before the test. But it is very difficult to access the S/C inside big LTVC. To solve the accessibility to the S/C inside LTVC, KARI designed an access fixture. This fixture provides easy access to the any S/C thus can help safe installation and saving time for the related work inside LTVC. This paper describes whole process for the design of the access fixture.

Objective: The aim of this study was to investigate the technology trend on developing helmets based on the analysis of Korean, US, European and PCT patents. Background: The usage of the personal protective equipment such as the safety helmet would be essential for preventing injuries and reducing the severity of injuries depending on the type of activity and the exposed environment. Method: Database of WIPSON was used for searching the patents. The objects were the Korean, US, European and PCT patents registered or opened from January 2011 to December 2014. The keyword to investigate was helmet, and International Patent Classification (IPC) was used for investigating the technology trend of the patents. Results: The cases of US patents annually increased, but the cases of European patents decreased. US patents belonged to all sections but Korean and European patents and PCT patents did not. The largest number of IPC, to which four areas' patents belonged, was 'Headwear' and the second largest one was 'Hygiene'. In the subgroup level, the most common largest subgroups were 'Parts, details or accessories of helmets' and 'Masks, shields, or hoods for welders'. Korean patents had the lowest ratio of single_IPC at 11%, but the ratios of single_IPC for US and European patents were 52%, respectively. 'Human necessities', 'Mechanical engineering', 'Physics', and 'Electricity' were used as a single_IPC, but lower levels of 'Performing operations', 'Chemistry', 'Textiles' and 'Fixed constructions' were used as multi_IPC. Most main applicants had patents which belonged to 'Human necessities'. Conclusion: The cases of US patents annually increased unlike others. The common technologies for creating the helmet were Parts of helmets under Headwear and Shields for welders under Hygiene. Many Korean patents tended to be categorized as multi_IPC, different from others. Application: To know the technological characteristic of patents would be helpful to initial stage developers.

Gastric cancer is the most common malignancy and the incidence is steadily increasing in Korea. The principal treatment modality for gastric cancer is surgical extirpation of tumor along with draining lymph nodes. Gastrectomy with D2 lymph node dissection has been well established as a standard of surgery and improved the survival of gastric cancer patients. Recently, technological advances are drastically reshaping the landscape of surgical treatment of gastric cancer. One of the most notable trends is that minimal access surgery becomes dominating the treatment of early stage diseases. For advanced diseases, the standard access surgery is considered a reference treatment. Although there is a pilot study underway to evaluate the feasibility of the application of minimal access surgery to advanced gastric cancer (AGC), the evidence for oncological safety is not yet provided sufficiently. Based on the recent randomized controlled trials, the extent of surgery for AGC has re-defined as para-aortic lymph node dissection dose not add any survival benefit while increasing surgery-related morbidities. In addition, it is now accepted as a standard operation omitting unnecessary procedures such as splenectomy and/or distal pancreatectomy for prophylactic lymph node dissection. Conceptual and technical innovation has contributed to decreasing morbidity and mortality without impairing oncological safety. All these recent advances in the field of gastric cancer surgery would be concluded in maximizing therapeutic index for gastric cancer while improving quality of life.

After 2001, the world aircraft industry grows consistently with world's economic recovery. The environmental changes after 9.11, including the market decent and revival, rise in oil price, and the environmental problems, make the aircraft industry change gradually. The increasing demand of point-to-point flight needs over 200 seat class large jets and changes the main model of regional jet over 100 seat class. And the needs of various flight schedule raises the demand of business jet and VLJ. The competition between airliners including the main streams, the regionals and the low prices goes harder and it needs more efficient airplanes which reduce the cost. In the military side, still the development of 5th generation fighter is proceeding and it diffuses to the more countries. Before its popularization, the 4th generation fighter is chosen for good alternatives of it. And there are some changes in the military demand after the war against terrorism. The army needs more unmanned reconnaissance and they want new aircraft which gives more accessibility.
