  • IT related services are available in the shipborne and maritime area. As their service requirements are requested diversely, the safe and reliable embedded system based device needs increase. There are two categories in embedded system : communication/control system and various user interface needed service system. In this paper, we propose the classification of embedded system in the shipborne and maritime area and provide two reference embedded system platforms and their components. One is low-level embedded reference platform of communication/control system and the other is high-level embedded reference platform of user interface oriented system.

  • Canada is a maritime nation. It has the world's longest coastline and second largest continental shelf. Canada's coast, if stretched, would circle the earth six times at the Equator. The 200 mile Exclusive Fishing Zone represents 32% of Canada's total territory. This maritime area is the size of continental Australia and eight times the size of Texas. Many major cities are coastal ports or are located on the St. Lawrence Seaway, the world's longest and heavily-used waterway. Much of Canada's trade goods are transported by water. Weather and climate are driven by ocean processes, determine the location and success of our important fishing, agriculture and forestry industries. Canada's fishing industry continues to be a major exporter of fisheries products and the mainstay of hundreds of small communities in coastal areas. Offshore oil and gas production, and the associated spill hazards, particularly in ice-infested waters, pose new environmental threats to our coastal areas. All these facts, and many others which for the sake of brevity we will not mention, lead to the necessity of a strong and credible ocean research activity in Canada.

  • Natural resource of the island and coastal regions is one of the most important element of ecological network system in Korea. Currently, there is trend that natural and biological resources such as fishing and tidal wetland have been used to local economic activation in island and coastal regions. According to the 5-days work in a week, island and coastal regions become important amenity resource of citizen's recreation area. Korea is peninsula surrounded by maritime. Especially, South and West Sea surrounded by many islands and tidal flat wetlands are emerging marine ecosystem and seascape in the world. Natural resource is limited, so we have to sustain those resource to current tourism. In this study, I would like to suggest that importance of cultural resource as well as natural resource for 'eco-cultural tourism' in order to keep both biological diversity and cultural diversity as amenity resource for future island economic activation in Korea.

  • Jeong YagYong, who are the SilHak Scholar during 18th to 19th century, wrote the Sadaegore with his pupil Lee Cheong. This work is the guide of diplomacy, which are asked to write from King Jeongjo. Although this book was completed after King Jeongjo's death, it harbors the King's thoughts about diplomacy or the relationship with China. Haebanggo, one chapter of the book, is about marine policy and how to treat the castaways. In this chapter, Jeong YagYong provides various ways to deal with these problems in marine area and sea refugee I will examine the Jeong YagYong's thought about the problems and ways to address these problems. Futhermore, I will inquire Jeong's opinion on the boundary in marine area. He recognized that many border transgressions happened in marine area at that time and considered that as urgent political affairs. Haebanggo consists of two parts. First part of the book is about protect own island from other countries. The rest part is about cases of dealing with castaways and their transgression. I argue that Jeong YagYong intended to make distinct borderlines in marine area and empathized the necessity of protecting Joseon's islands from other countries.

  • Recently, International Maritime Organization has been developing e-navigation implementation strategy plan, which is focused on various services for vessel safety navigation. Then, different kinds of software will be developed in maritime area and with this, the quality issues are to be expected becoming more important. In this paper, we adopt software refactoring techniques to reduce the complexity of structure on source code level. It makes software program more effective to understand and modify, without any change of outward behavior. The existing AIS broadcast server program is used as an example for our trial, and calculating coupling and cohesion metric are introduced to analyze the refactoring effect, taking account of the maintainability of IEC/ISO9126 software quality standards.

  • Over the past decades, information and communication service providing safe and efficient navigation have been tried in maritime area. However, there were provided different ways such as different protocol or different policy. It made hard to serve efficiently. The introduction of MSI as a part of e-navigation development can be a kind of concepts to solve this problem. This paper tries to suggest a conceptual design of onboard application middleware to be able to communicate the shore-side maritime safety information system, take into account the reuse of open-source software.

  • International Maritime Organization (IMO) recommends maintaining a positioning accuracy of global satellite navigation system (GNSS) within the range of 10 cm and monitoring its integrity. In order to provide the positioning accuracy of 10 cm or better, high-precision correction information must be used based on the carrier phase of the satellite signal. Furthermore, in order to monitor the integrity of this, the errors should be overbounded in the process of generating correction. In this paper, we analyze the GNSS integrity monitoring methods in high-precision position service currently in operation. The integrity monitoring technique of the wide area augmentation system (WAAS) of the U.S. is studied. As a conclusion, we propose the integrity monitoring method of Korean high-precision GNSS service in maritime area.

  • In this study, the reproducibility of the simulated current climate by using two regional climate models, such as Seoul National University Regional Climate Model (SNURCM) and Weather Resuearch and Forecasting (WRF), is evaluated in advance to produce the standard regional climate scenario of future climate. Within the evaluation framework of a COordinated Regional climate Downscaling EXperiment (CORDEX), 28-year-long (1978-2005) regional climate simulation was conducted by using the Hadley Centre Global Environmental Model (HadGEM2-AO) global simulation data of the National Institute of Meteorological Research (NIMR) as a lateral boundary forcing. The simulated annual surface temperatures were in good agreement with the observation; the spatial correlation coefficients between each model and observation were over 0.98. The cold bias, however, were shown over the northern boundary in the both simulated results. In evaluation of the simulated precipitation, the skill was reasonable and good. The spatial correlation coefficients for the precipitation over the land area were 0.85 and 0.79 in SNURCM and WRF, respectively. It is noted that two regional climate models (RCMs) have different characteristics for the distribution of precipitation over equatorial and midlatitude areas. SNURCM shows better distribution of the simulated precipitation associated with the East Asia summer monsoon in the mid-latitude areas, but WRF shows better in the equatorial areas in comparison to each other. The simulated precipitation is overestimated in summer season (JJA) rather than in spring season (MAM), whereas the spatial distribution of the precipitation in spring season corresponds to the observation better than in summer season. Also the RCMs were capable of reproducing the annual variability of the maximum amount and its timing in July, in which the skills over the inland area were in better agreement with the observation than over the maritime area. The simulated regional climates, however, have the limitation to represent the number of days for extremely hot temperature and heavy rainfall over South Korea.

  • Anthropogenic emissions of greenhouse gases, particularly carbon dioxide($CO_2$) which arises mainly as wastes from the fossil fuel burning processes, are causing global warming. The effects of global warming become increasingly felt all over the world including sea level rise and extreme weather. The more direct consequences of the elevated atmospheric $CO_2$ on the ocean is the acidification of the surface ocean which brings a far reaching adverse impact on the life at sea and probably on the whole ecosystem of the planet. Improvement in energy efficiency and use of alternative energy sources are being made to reduce $CO_2$ emissions. However, a rapid transition to alternatives seems unachievable within a few decades due to the constraints on the associated technology and socio-economic factors in the world, since fossil fuels make up approximately 85% of the world's commercial energy demands. It has now been recognized that capture and geological sequestration of $CO_2$ could significantly reduce its emissions from fossil fuel utilization and therefore provides the means to rapidly achieve large reductions in $CO_2$ emissions(excerpts from London Convention, LC/SG 28, 2005). In Korea, well-developed sedimentary basins are spread over the vast continental shelf and slope regions, whereas, the land is densely populated and limited in area. Consequently, the offshore area is preferred to the land for the sites for geological sequestration. The utilization of the offshore area, however, may be subject to international agreements including London Convention. In this paper, the recent trends in technologies and regulations for $CO_2$ capture and geological sequestration are described to encourage its applications in Korea.

  • There have many research papers to see China's evolution of maritime strategy and naval modernization in terms of its naval mind-set. However, this article focuses on assessing how China uses its all sorts of maritime strength to achieve 'a building maritime great power.' The aim of the article is to introduce a new perspective to this debate by analysing China's diversified ma maritime capabilities and a new way of implementation in maritime security strategy. In recent years, China has been developing not only unpredictable maritime military capabilities but also maritime supporting forces - Coast Guard and Maritime Militia. And recently China adopted up-to-date operational concept aimed at gaining military superiority in Asia-Pacific waters. By taking salami slicing strategy, gray zone strategy and cabbage strategy, China has been trying to exercise surpassing influences in regional maritime area, also in western Pacific region. This article provides a stepping stone to comprehend the aspect of China's recent maritime strategic actions, especially in Yellow Sea. In conclusion, this article suggests some policy recommendations for countering China's coercive maritime strategy. First, Korea should make sure a strategic concept of maritime security, instead of land warfare focused strategic concept. Second, it is needed to set up suitable naval forces for actively responding to neighbor nation's offensive actions.
