Several studies have been performed globally on the construction of integrated systems that are available for the integrated use of 3D geographic information on terrain and oceans. Research on 3D geographic modeling is also facilitated by the application of Lidar surveying, which enables the highly accurate realization of 3D geographic information for a wide area of land. In addition, a few marine research organizations have been conducting investigations and surveying diverse ocean information for building and applying MGIS(Marine Geographic Information System). However, the construction of integrated geographic information systems for both terrain and oceans has certain limitations resulting from the inconsistency in reference systems and datum levels between two data. Therefore, in this investigation, integrated geospatial information has been realized by using a combined topographical map, after matching the reference systems and datum levels by integration of airborne Lidar data and multi-beam echo sounder data. To verify the accuracy of the integrated geospatial information data, ten randomly selected samples from study areas were selected and analyzed. The results show that the 10 analyzed data samples have an RMSE of 0.46m, which meets the IHO standard(0.5m) for depth accuracy of hydrographic surveys.

Technology planning is becoming increasingly important with the rapid development and decline of technology. Technology roadmapping is a tool used to select whether the specific technique of technology planning should pursue which technology and in which time. This technology is important to secure the uncertain future since it will provide a method that is able to share the goals and strategies between organizations. Therefore, technology tree in the planning stage of the problem would be a very useful tool. In this study, both domestic and international technology tree application cases were analyzed to be able to derive a plan for ensuring that the research performed and the requirements are met for the future development and implementation of a convergence portal system. The six major systems that aim at water hazard information platform are basic information providing system, analysis information providing system, water disaster theme providing system, national disaster information system, water disaster augmented reality system and open information platform system. General standardized core technologies corresponding to the needed functions in each target system are derived through brainstorming, and classified according to the technology field to derive the technology tree.

The extant entrepreneurship research has emphasized the development of businesses by recognizing and exploiting new opportunities rather than the development of people in organizations. To remedy this issue, scholars recently suggested the concept of humane entrepreneurship where the traditional view on entrepreneurship is enhanced by the human-centered logic. However, more scholarly work is needed to develop the concept of humane entrepreneurship as a new perspective of the entrepreneurship research domain. In this article, we attempt to enhance the research on humane entrepreneurship by suggesting its theoretical foundations and identifying the underlying dimensions of humane entrepreneurship with empirical data. This study suggests the five disciplines in management studies as theoretical foundations of humane entrepreneurship: strategic entrepreneurship, stakeholder theory, transformational leadership, motivation theory, and humanistic management. Also, we developed the measurement of humane entrepreneurship and tested its reliability and validity by collecting data from 19 countries. The results showed that the concept of humane entrepreneurship is composed of two dimensions, humane and enterprise cycles. Finally, this study provides further research agenda in the domain of humane entrepreneurship research.

The Republic of Korea is the maritime country of which its infrastructure of the country's development is based on maritime trade. This can be easily understood according to degree of dependence upon foreign trade, which is the economic indicator for expressing one country's economic characteristics. In 2008, the degree of dependence upon foreign trade of Korea is 83.5%, and this figure is much higher than that of Japan and China, which is 28.8% and 68% respectively. This in turn means that the development of Korea, and also the security of Korea depends greatly on safety of the sea. On the other hand, there is a growing trend that threats to the maritime security of Korea increases as examples seen in Somalia pirates. Thus we could say that interest on this issue should increase and also measures to counter those threats should be prepared. Also Korea should take the maritime security as important as critical factors as national security, which is similar to military threats from North Korea. Therefore all citizen's interests on the issue should be raised, and organizations that are capable of mutually integrating the functions related to maritime security should be established. Finally, Korea should actively participate international efforts on maritime security, and secure maritime security of our nation therefore contribute to the nation's prosperity and future development.

Forest soil carbon model is a useful tool for understanding complex soil carbon cycle in forests and estimating dynamics of soil carbon to climate change. However, studies on development and application of the model are insufficient in Korea. The need for development of Korean model is now growing, because there are notable problems and limitations for adapting overseas models in Korea to meet the requirements of the international organizations such as IPCC, which demands highly reliable data for national reports. Therefore, we have studied 7 overseas forest soil carbon models (CBM-CFS3, CENTURY, Forest-DNDC, ROMUL, RothC, Sim-CYCLE, YASSO), analyzed and compared their structure, decomposition mechanism, initializing process and, input and output data. Then we evaluated applicability of these models in Korea with three criteria; availability of input data, performance of model, and possibility of regional modification. Finally, a systematic process for applying a new model was suggested based on these analyses.

In order to reduce marine accidents using advanced information and communication technology, various research and development projects are conducted globally on e-Navigation related technologies and services. Existing studies do not provide policy measures for LTE-M. In order for these technologies and services to be installed on vessels and to contribute to the prevention of accidents at sea, the law should be expand operational organizations and systems. In particular, communication equipment and related technical standards should be prepared, and its digital communication technology (LTE-M, VDES, Digital-MF / HF, etc.) In this study, we conducted short, medium, and long term performance assessment of the identification system and the policy for effective implementation of Korean e-Navigation. We presented a visible plan of the relevant policy. For example, e-Navigation core services, e-Navigation communication networks and operating systems, e-Navigation international standard leading technologies and e-navigation services activated in the field. To do this, we conducted research based on the progress data of the Korean e-Navigation project, which was led by the Ministry of Maritime Affairs and Fisheries, and conducted research discussions with practitioners and experts in related fields. As a result of this study, it is expected that the proposed policies will contribute to the reduction of marine accidents, the promotion of the maritime industry and the development of additional government policies for national security.

Information service organizations that provide science and technology information with a relatively short information life cycle for free or paid are in need of reflecting rapidly changing user needs and behaviors and grafting the latest technologies. The purpose of this study is to derive improvements for each system by comparing and analyzing general recognition of science and technology information users' domestic and foreign science and technology information sites and importance by science and technology information attributes. A total of 816 users of science and technology information participated in the online survey, and the collected data were analyzed by quantitative methods including IPA (Importance Performance Analysis) technique. The importance was evaluated by the impact value calculated through regression analysis. As a result of data analysis, the general recognition of users on science and technology information sites was relatively high in national science and technology information services, and Google Scholar and Science Direct were also high. Google Scholar was found to have more strength than improvement. A better understanding of the user's preferred system is a good driving force for improving the lack of existing systems. It is necessary to improve the information retrieval of the science and technology information service system, that is, to improve the search speed and functions, and also to improve the user interface with improved convenience and usability.

UN, OECD, ITU and other international organizations regularly announce ISI (Information Society Index) to utilize in establishing and evaluating information policies. ISI is utilized as important data for countries to evaluate their information policy performance and select future projects. As the advancement of information systems, the importance of information security has been emerged. Accordingly, NISI (National Information Security Index) has been required. NISI number is the most clearly figure to express the characteristics of a particular group's information security. It can be utilized in determining information security policies. Currently, questionnaire method has been used to calculate NISI number. But there is an absolute lack of statistical data, and the reliability of surveyed statistical data is problematic. The objective of this paper is to show how to collect precise micro data of each company's information security index numbers, and to develop an OLAP database system which calculating NISI numbers by using those micro data. In this process of the survey, we presented the technique to collect the data more systematically, and to analyze the data without using questionnaire method. OLAP architecture performs only well on the facts that are summarizable along each dimension, where all hierarchy schemas are distributive. Therefore we transformed the non-distributive hierarchy schema into the distributive hierarchy schema to implement OLAP database system. It is thought that this approach will be useful one from an implementation and schema design point of view.

Since the Arab spring in 2010, SNS prompted discussions about the roles to organize collective actions. First of all, mobile media and SNS help to mobilize both on and offline social movement, second, to create new forms of collective actions, third, to organize social movement organizations across the world, fourth, to empower movement participants to develop new collective identities. On the other hand, the same technologies also hinder social movements from developing continuity and dedication. In addition, the problems of digital divide might aggravate the divisive process to organize collective actions across the world. This research is built on these ongoing arguments about the potentials and limitations of new media technologies. In particular, this research tries to move beyond the confrontational approaches to the media through the case study of Save The Jeju Island social movements on Facebook. The movement SNS on Facebook aims to provide as well as organize international SMOs and activists that might help deeper understandings on the potentials and limitations of online communication strategies for global social movements.

In the post-Cold war world, the threat of terrorism is emerging as the most formidable challenge. The terrorist attacks including 9.11 World Trade Center attack have proved such challenge. It has become apparent that no country is safe from the scourage of terrorism. The region of the southeast Asia is no exception to this trend. The Bali bombing of 2002, killing about 200 innocent people, demonstrated that the threat environment had significantly altered. Today, local and regional groups such as Jemiah Islamiah can conduct terrorist operations as devastating as those carried out by Al Qaeda. As fighting terrorism is a complex multi-dimensional task, the responsibility for fighting terrorism must not rest with a single government. The burden must be shared by both the local governments and international communities. In addition, To prevent another bombing of the scale of Bali, countries in the region of southeast Asia must respond decisively. The purpose of this study is to examine the current situation on terrorism in the southeast Asia and to provide perspectives on future terrorism in this region. To foster the better understanding, historical survey on the terrorism in the region and local terrorist groups' network with the foreign terrorist organizations including Al Qaeda have been researched. Based on the result of the research, this paper provides a perspectives and evaluation on the future terrorism in the southeast Asia. It also provides an implications for our reference in the war against terrorism.
