This study is to investigate global logistics strategies of Korean electronics companies. in terms of service parts. According to the survey, Korean electronics companies were pursuing multi-level global logistics network such as global, continental, national, regional and service center echelon for improving the efficiency of service parts global logistics. Especially there was a tendency of developing new continental distribution centers. And the companies were exploiting efficiency through inventory control by multi-level echelon, demand forecasting by the product life cycle and supply and service lead time management. But there were some insufficient factors for the efficiency of global logistics operation at the construction of worldwide real time logistics information system and pursuit of the efficiency on the whole network including subcontractors. For the future competitive advantage of the Korean electronics companies, the following are suggested: 1) the establishment of arranged logistics channel adjusting each company's global strategy, 2) the construction of worldwide real time logistics information system, 3) the reengineering of all logistics procedures such as order processing, shipping, inventory control, etc., 4) the enhancement of the ratio of the supply from the external companies and the internal manufacturing subsidiaries at each continent, 5) and the pursuit of operational internalization of external subcontractors.

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.

The utilization of Digital and Social Network has become be a key success factor in business operations as information technologies evolve rapidly. This study is to identity the relationship between ICT & digital utilization, global orientation and export marketing capability in Korean SMEs. Survey data of Korean SMEs in south regional areas was collected and analyzed for empirical hypothesis test by PLS structural equation method. The key findings are as follows. First, ICT utilization such as SNS, homepage and online portal does not impact directly on export marketing capability. It means that SMEs would not still take advantage of utilization of social network availability. Second, ICT utilization has positive influences on global market orientation and global network orientation. Finally, both global market orientation and network have significant impacts on export marketing capability. In conclusion, global orientation has full-mediation effects on relationship between ICT capability and global marketing. This study provides evidences and some practical insights that digital utilization have indirect influences on global marketing through global markets and network orientation in Korean SMEs. In information technology era, ICT utilization will play an important role in the process of SMEs' internationalization. Therefore, for sustainable growth and survival SMEs should manage and intensify ICT capability more strategically as one of core competence. The value of ICT capability in SMEs would be depended on their strategic perspectives toward digitalization. Additional empirical research about digital capability based on larger sample will be needed.

Information Grid that connects Sensor Grid and Shooter Grid with network is the core infrastructure to enable the NCW concept. The U.S. DoD(Department of Defense) has developed the GIG(Global Information Grid) as the Information Grid that connects all of the DoD mission areas. Then the U.S. DoD has incrementally constructed GIG. In this respect, the case of the U.S. DoD's GIG construction refers to materializing ROK Information Grid concept. Therefore we studied the U.S. DoD's GIG construction trend and analyzed ROK's GIG construction trend. In result this paper proposes the way to develop and construct ROK's GIG.

Starting with the observation of sunspots in 1987, Korea Astronomy and Space Science Institute (KASI) has developed and installed various ground-based instruments for space weather research in Korea. Recently, SNIPE and CODEX are also being developed as space-based instruments. Expansion of the observation area and simultaneous observation have become important in the study of space weather. We have started Next-Generation Space Weather Observation Network Project this year. In order to establish a solar observation network, we planned to develop the Next Solar Telescope (NxST) which is a solar imaging spectrograph, and to install three NxST in the northern hemisphere. And we also planned to develop the Thermosphere-Ionosphere-Mesosphere Observation System (TIMOS), Global Navigation Satellite System (GNSS), and Geomagnetic packages, and install them in about ten sites over the world, for the purpose of establishing a global observation network for the near-earth space weather. We can take simultaneously observed space weather data in the global area, and are expecting it will play an important role in the international community for space weather research. We also have a strategy to secure observational technologies necessary for big space missions in the future, through this project.

This article aims to explore and discuss research trends in global cruise industry using keyword network analysis. We visualize keyword networks in each of four groups of 1982-1999, 2000-2004, 2005-2009, 2010-2014 based on the top 20 keyword nodes' degree centrality and betweenness centrality which are selected among four centrality measurements, comparing them with frequency order. The article shows that keyword frequency collected from 240 articles published in international journals is subject to Zipf's law and nodes degree distribution also exhibits power law. We try to find out research trends in global cruise industry to change some important keywords diachronically, visualizing several networks focusing on the top two keywords, cruise and tourism, belonging to all the four year groups, with high degree and betweenness centrality values. Interestingly enough, a new node, China, connecting the top most keywords, appears in the most recent period of 2010-2014 when China has emerged as one of the rapid development countries in global cruise industry. Therefore keyword network analysis used in this article will be useful to understand research trends in global cruise industry because of increase and decrease of numbers of network types in different year groups and the visual connection between important nodes in giant components.
