CITIS(Contractor Integrated Technical Information Service) is a service standard which specifies guidelines which are required for the fulfillment of a contract between a purchaser and a supplier. It was initiated as a military standard and is now becoming a commercial standard. In this paper, we propose how the guidelines, which were usually developed by Client/Server methods in previous works, can be implemented in WWW environments, and show a prototype which can be used for the confirmation of CAD drawings between contractors(purchaser and provider). We have a hope our study can provide a small foundation for the building of CITIS references.

The Korean state evolved as a distinct entity in a region of major power convergence and conflict. All states, as human constructions, seek sovereignty and life security of their subjects/citizens, and are rotted in organic society. In the Republic of Korea, constitutional order has provided a framework for political action and a succession of regimes - authoritarianism, military dictatorship, and constitutional democracy. Since 1960 two paradigms have undergone a cycle of growth and decline, and a third, since the 2016 candlelight demonstrations in Gwanghwamun, may be the beginnning of a third generation paradigm - populist constitutionalism.

In computer simulation models the output from the computer code is often deterministic, i.e., running the code twice with the same values for the input variables would give the same output. It is discussed why the response surface method with polynomial approximation for the true response function is a good approximation to the computer experiments model. A sequential strategy to find the proper reduced quadratic polynomial model is illustrated with a case study in the military war game computer simulation model.

Recently, virtual reality technologies have been rapidly developed and realtime virtual simulation methods have been extensively employed for several application areas such as game, sports, manufacturing, military, and so on. A 3D database in realtime virtual simulation plays a key role because it makes users feel reality in virtual space. In a application view of 3D database, a systematic construction approach is required to reduce its construction time and increase its quality. However, many researches have been mostly focused on realtime graphic issues and its key technologies. In virtual simulation of transportation equipments, this paper proposes a systematic construction process of 3D database consisting of four stages as follows: 1) determine the activity space of a equipment, 2) collect data related to 3D database construction, 3) make a 3-dimensional modeling strategy, and 4) generate and evaluate a 3D model. This paper also introduces a new procedure of 3D environment modeling, which summarizes and expands our modeling experiences, to be used as a modeling guide.

The purpose of this paper is to increase the competitiveness of firms by establishment of green marketing strategy and its application to a new alternative energy development, ultimately contributing to the advancement of national economy. This study adopted an integrated approach to develop a strategic theory of 'Sun Tzu on the Art of War' that is one of the oldest military treaties and still applicable to today's management development. It applies to the empirical result from a new alternative energy development. For more qualitative improvement of this paper, it needs further detailed studies in both theory and practice in green marketing theory that is applicable to the new alternative energy development.

This work presents an iterative mesh partitioning approach to improve the efficiency of parallel substructure finite element computations. The proposed approach employs an iterative strategy with a set of empirical rules derived from the results of numerical experiments on a number of different finite element meshes. The proposed approach also utilizes state-of-the-art partitioning techniques in its iterative partitioning kernel, a cost function to estimate the computational cost of each submesh, and a mechanism that adjusts element weights to redistribute elements among submeshes during iterative partitioning to partition a mesh into submeshes (or substructures) with balanced computational workloads. In addition, actual parallel finite element structural analyses on several test examples are presented to demonstrate the effectiveness of the approach proposed herein. The results show that the proposed approach can effectively improve the efficiency of parallel substructure finite element computations.

There are unimaginable possibilities ahead of us. As a result, it is difficult to predict the future, but the prediction itself is not meaningless. This is because it can have the flexibility to cope with contingencies by predicting various possibilities. This study was conducted to explore extreme events (X-event) in the Korean population sector. To this end, in-depth interviews were conducted with experts from the Korea Army Research Center for Future & Innovation and the Army College, and based on this, significant research results were derived that population problems such as population decline and aging can affect various fields such as economy. With this study, we hope that discussions on extreme events (X-event) that can occur in our society will be further activated.

This paper is designed to make a national strategic concept for the ROK's maritime security and to explore cooperation directions for the ROK Navy and Coast Guard in order to implement the newly-made maritime security strategic concept. As strategy is composed of three main categories(goals, ways, means), the goal of the ROK's maritime security strategy is 'Safe and Affluent Sea' and the way to realize the goal is the principle of cooperative leverage, and the means as tasks to implement the strategic concept are maritime safety, maritime security, and maritime stewardship. The concept of national fleet as used in the US is applied to promoting the cooperation between the ROK Navy and Coast Guard. Thus, under the newly-established maritime security strategic concept along with the national fleet model, followings are suggested as policy proposals for facilitating mutual cooperation between the ROK Navy and Coast Guard in dealing with not only traditional threats but also non-traditional treats at sea and from the sea as well. First, the ROK Navy and Coast Guard has been making efforts to enhance interoperability between the two sea services. However, the mutual cooperations have been focused mainly on areas on operational level rather than policy level. Therefore, the two sea services are recommended to enlarge exchanges and cooperation in policy areas. Second, there are still demands for further cooperation areas between the two sea services in command and communications. The interoperability in C2 between the two needs to be upgraded even to the areas of anti-terrorist activities ar sea, ASUW, ASW, maritime interdiction, etc. Third, mutual comparability between the two needs to be reflected in the maritime forces development to ensure the comparability in UNREP and other logistics areas. Fourth, the standardization of logistical materials and equipments is needed as a way of sustaining operational capability and logistical capacity for the ROK Navy and Coast Guard as well. Fifth, the ROK Navy and Coast Guard are recommended to participate more actively in international maritime cooperation activities such as PASSEX. Sixth, Complementary laws and regulations need further to be revised and to be newly made for collectively managing swiftly maritime accidents and natural disasters at sea.

On July 3~4, 2014, the Chinese President Xi Jinping's state visit to Seoul might be seen as a step on the path toward strategic outcomes for both country. For South Korea, Seoul shrewdly retains some degree of self-reliance by balancing between ROK-China strategic cooperative partnership relationship and ROK-US alliance. For China, Beijing appears to put its interests on the Korean Peninsula increasingly within China's larger geopolitical influence. To what extent can ROK-China relationship maintain futuristic strategic cooperative partnership between them? As we observed joint press communiques of the Chinese President Xi Jinping's state visit on July 3, 2014, four agendas of bilateral relationship between Seoul and Beijing can be identified: intractable rivalry between the two great powers, North Korea nuclear issues, disparities of their displeasure with Japan denying the past wrongdoing and enhancing its military capabilities and Chinese imposing of its core interests on its Korea policy. With these evolving strategic environments, however, China and the ROK appear justifiably be pleased with the state of their relations: their strategic cooperative partnership is the cornerstone of peace and prosperity in the Asia-Pacific or Indo-Pacific region and continues to grow broader and deeper.
