  • Planetary global localization is necessary for long-range rover missions in which communication with command center operator is throttled due to the long distance. There has been number of researches that address this problem by exploiting and matching rover surroundings with global digital elevation maps (DEM). Using conventional methods for matching, however, is challenging due to artifacts in both DEM rendered images, and/or rover 2D images caused by DEM low resolution, rover image illumination variations and small terrain features. In this work, we use train CNN discriminator to match rover 2D image with DEM rendered images using conditional Generative Adversarial Network architecture (cGAN). We then use this discriminator to search an uncertainty bound given by visual odometry (VO) error bound to estimate rover optimal location and orientation. We demonstrate our network capability to learn to translate rover image into DEM simulated image and match them using Devon Island dataset. The experimental results show that our proposed approach achieves ~74% mean average precision.

  • As neoliberal Globalization is reinforced, the debating of international stage about cultural market is heated up. People who insist market opening claim that cultural product has to be handled in condition such as other goods. However, the dissenter of cultural market-opening assert 'cultural exception' in goods trade because culture affects in individual and community consciousness and identity. The dispute encompassing cultural market raise the concept of Global Governance which presents theoretical frame about international society's decision-making and administration. Thus, this article explore international norms which encompass cultural market and its stakeholder through Global Governance frame. Specifically, first, this article review the theory of Global Governance. Second, this article examine international norms such as WTO, GATT, GATS, and also study its opponent who advocate 'cultural diversity'. Consequently, this article argue that the debating and conflict about cultural market should be resolved, not by hegemony state, by Global Governance frame which all stakeholder take part in.

  • Global women's magazines have been approached as a significant site for exploring the dynamic interaction between global and local forces. Unlike other global media products which are imported from overseas, global women's magazines are published through the cooperation with local companies. These ownership patterns allow local editions of global women's magazines to negotiate the tension and contradiction between the global media and local publishers. Thus, the main purpose of this research is to investigate the dialectic interaction between the global and local forces in the production of international women's magazines in Korea. To explore the dynamic interaction between the global and local forces, both globalization and localization efforts of international women's magazines which occur during the production process were examined through in-depth interviews with personnel in the magazine industry. The result of this research showed that international women's magazines are not a mere part of global media but a 'glocalized' media product, which carry local content via global formats. The form of international women's magazines seems to be more globalized or standardized, while the content (text) is relatively localized by reflecting local readers' interests and the cultural values of Korean society.

  • As the proliferation of smart phone, almost every user has one's own smart phone, and the user could get the global position and location based services using GPS system outdoors. But indoor positioning system using GPS does not work, and it could not detect global position using TDOA local positioning system. In this paper, a new indoor global positioning system for smart phone employing GPS receiver and electronic compass device is proposed with the TDOA local positioning system using acoustic signal, and the performance and the experimental result are described.

  • In this paper, we propose a map alignment method for maps generated by point-line monocular SLAM. In the proposed method, the information of feature lines as well as feature points extracted from multiple maps are fused into a single map. To this end, the proposed method first searches for similar areas between maps via Bag-of-Words-based image matching. Thereafter, it calculates the similarity transformation between the maps in the corresponding areas to align the maps. Finally, we merge the overlapped information of multiple maps into a single map by removing duplicate information from similar areas. Experimental results show that maps created by different users are combined into a single map, and the accuracy of the fused map is similar with the one generated by a single user. We expect that the proposed method can be utilized for fast imagery map generation.

  • This paper proposes the Global Clipboard System and presents a preliminary study on it. The clipboard is a temporary storage used to copy and paste some contents between application programs in Windows Operating System. The proposed Global Clipboard is a contents delivery system that extends the concept of the existing local clipboard to Internet. The Global Clipboard System operates in two steps. An application user can upload selected contents to the Global Clipboard by typing consecutive keys of Ctrl-C and Ctrl-Shift-C easily. And other users can download and utilize the contents from the Global Clipboard by typing Ctrl-Shift-V and Ctrl-V keys consecutively. The proposed Global Clipboard can deal almost data like simple texts, screen capture images, files, and directories. In this paper, we developed a global clipboard server, a Windows application, and an Android application. We have conducted experiments about functions of the Global Clipboard and also compared delay times between 4 applications such as e-mail, Kakao, Google Drive, and the Global Clipboard. The results of the evaluation show that the time delay spending in sending and receiving contents is shortest when the Global Clipboard is used.

  • We developed and evaluated a fluorescence-based optical DO sensor (OS-100, Global Optical Communication Ltd., Korea) for long-term monitoring of the dissolved oxygen concentration in waste water treatment. Fluorescent sensing membrane containing $Ru(Dpp)_3{^{2+}}$ (tris(4,7diphenyl-1, 10-phenanthroline) ruthenium(II)) was prepared with GA sol-gel matrix and coated on a quartz plate by sprayed method. Properties of sensor film exhibit deviation about ${\pm}1%$ under wide range of DO concentration from 3 to 10. The developed optical DO sensor was actually mounted in waste water from dyeing industry and successfully applied for on-line DO monitoring. Online monitoring results showed the changes of DO concentrations in wastewater treatment processes with accuracy better than ${\pm}2%$ during the 6 months measurements period in vicious environmental conditions.

  • Air pollution is a global challenge that not only threatens public health, but also takes away lives. Strategic communication, in other words, public relations, is an essential way of tackling air pollution and managing the risks involved. Engaging global citizens into the public sphere requires the building of a sense of collectivity and duty on achieving clean air. Strategies and policies on an international scale that are based on the theoretical framework (Behavior Procedure Model) and focus on leading citizens into the mature and unified Collectivity during the observance of the 'International Day of Clean Air for blue skies' are crucial. Notably, the Asian continent has inevitably found itself at the crossroad between economic growth and environmental protection, and has even been observed to be pursuing a passive response to air pollution. The key communication strategies are supported by the three goals, which include: expanding existing communities and building a new Collectivity, supporting international solidarity and individual member state activities, and implementing systems and structures. The key goals can be further specified into six strategies. This paper has analyzed global problems and discussed possible communication strategies to increase public engagement for the observation of the 'International Day of Clean Air for blue skies.' It will be the responsibility of all nations to implement the aforementioned strategies and policies as well as promoting global action.
