인공지능은 우리 실생활과 밀접하게 연관되어 다양한 분야에서 혁신을 주도하고 있다. 특히 인공지능을 보유한 이동수단으로서, 자율무인이동체의 연구가 활발하게 이루어지고 곧 실용화를 앞두고 있다. 자율자동차와 무인기 등이 스스로 경로를 설정하고 목적지까지 이동하기 위해서는 정확한 위치정보를 제공하는 항법장비가 필수적이다. 현재 운용되고 있는 이동수단들의 항법은 대부분 GPS에 의존하고 있다. 그러나 GPS는 외부 교란에 취약하다. 지난 2010년부터 북한은 수차례 GPS교란을 감행하여 우리 측에 이동통신, 항공기 운항 등에 심각한 장애를 유발했다. 따라서 자율무인이동체의 안전성을 보장하고 교란으로 인한 피해를 방지하기 위해서는 신속한 상황판단과 대응이 요구된다. 본 논문에서는 빅데이터, 머신러닝 기술을 기반으로 John Boyd의 OODA LOOP Cycle(탐지-방향설정-결심-행동)을 적용한 조치방안 도출과 결심을 지원하는 GPS 전파교란 대응체계를 제시하였다. Artificial intelligence is closely linked to our real lives, leading innovation in various fields. Especially, as a means of transportation possessing artificial intelligence, autonomous unmanned vehicles are actively researched and are expected to be put into practical use soon. Autonomous cars and autonomous unmanned aerial vehicles are required to equip accurate navigation system so that they can find out their present position and move to their destination. At present, the navigation of transportation that we operate is mostly dependent on GPS. However, GPS is vulnerable to external intereference. In fact, since 2010, North Korea has jammed GPS several times, causing serious disruptions to mobile communications and aircraft operations. Therefore, in order to ensure safety in the operation of the autonomous unmanned vehicles and to prevent serious accidents caused by the intereference, rapid situation judgment and countermeasure are required. In this paper, based on big data and machine learning technology, we propose a countermeasure system for GPS interference that supports decision making by applying John Boyd 's OODA loop cycle (detection - direction setting - determination – action).

Lately, encountering the IMF economic crisis, corcorations are reorganizing the system. The tax management becomes the bic issue not only in the enterprise but also in the research. Owing to the change of the national management environments, the reorganization of system is unavoidable, but the enormous burden of taxation makes the rearrangement difficult. Therefore the improvement in the taxation system to remove the obstacle of taxation is necessary. To cope with the change of the management environment, the government revised the tax law in December 1998 and established the several taxation systems for the coalition and division of corporations. Before it, whenever meeting those problems, the government dealt with them sporadically. But this revision is the systematic tax law related with the coalition and division of enterprises. Especially as the division of enterprises is carried out for the first time, Korea will have the advanced taxation system. Generally, the taxation system related with the coalition and division of corporation includes criticism and disputes in explaining and executing the actual tax law. Due to this, in foreign countries, the taxation system connected with the reorganization of companies belongs to the complicated tax area and remains as the long-standing problem. In the case of Korea, the taxation system about the change of the organization of corporation is the first attempt and the cases of execution are insufficient. Therefore many difficulties are expected in enforcing the tax law. The purpose of this study is to classify the several theories about the division of companies and to systemize the theories around the division of corporations.
