In this study, we discuss on the elements necessary for the successful introduction of "Advanced Surveillance System". The ROK.Army leads countless changes with「Defense Reform 2.0」. And introduction of scientific system is core discourse for the「Defense Reform 2.0」. The background of this change is the necessity of responding to the demands of the Revolution 4.0 and strengthening of the troops. So, the 「Defense Reform 2.0」 will transform the current personnel-based system to a high-tech based one. It is same for surveillance system. The paradigm of surveillance system is changed by introduction of "Scientific Surveillance System" and "Coastal Complex Surveillance System". However, the development of the operating system seems to be lagging behind that of the equipment. The introduction of "Scientific Surveillance System" and "Coastal Complex Surveillance System" change the surveillance operation from standing guard duty for one sector by two sentry to monitoring multiple sector by one CCTV control agent. But it is organized without considering the capacity of the agent that the number of screens monitored by one CCTV control agent. In this study, it was confirmed that the cause of the failure of surveillance operation is this problem in the last 5 years. Therefore, we can confirm that the development of the operating system-that is constructed by "Human resource", "Security regulations", "Security verification system"- is as important as the development of the equipment. so, we confirm the development direction of the operating system to efficiently operate the "Advanced Surveillance System".

The purpose of this study was to provide basic quantitative data to minimize the impact occurring during forward breakfall by the comparative analysis of kinetic factors through 3D motion analysis and analysis of GRF of the forward breakfall of the martialarts targeting 10 skilled and 10 unskilled subjects. The following are the findings. First, the total time taken for forward breakfall of the martial arts showed 1.53±0.04 s for skilled, and 1.41±0.06 s for unskilled subjects. Second, forward breakfall of the martial arts operation showed significant left and right position of center of mass in P2, P3, and P4. In addition, the unskilled subjects showed larger forward and rearward position in P1, P2, P3, and P4, while the skilled subjects showed larger vertical position in P2. And the unskilled subjects showed faster forward and rear movement of center of mass in P2, P3, and P4, respectively. And unskilled subjects showed faster vertical velocity of center of mass in P2 and P3. Third, as for the upper extremity joint angle during forward breakfall, skilled subjects showed larger right shoulder joint angle in P4, and unskilled subjects showed larger left shoulder joint angle in P2 and P3. Unskilled subjects showed greater elbow joint angle both right and left side in P1 and P3, and skilled subjects demonstrated larger wrist joint angle both right and left side in P1. Fourth, the forward breakfall of the martial arts did not show any difference between left and right side in the GRF, but unskilled subjects proved a significantly greater forward and backward GRF in the secondary point of impact(E3) both right and left sides. The skilled subjects showed a significantly greater vertical GRF in the primary point of impact (E2), and unskilled subjects showed a larger vertical reaction force in the secondary point of impact (E3), respectively.

The Korean military is preparing for successful manpower reduction using advanced science and technology, in addition to carrying out the initiative of the Defense Innovation 4.0. Accordingly, studies on core technologies related to defense reform have been conducted both internally and externally in the military, and the corresponding results have also been applied. Nevertheless, compared to the development of such technologies, it is considered necessary to have more preparation for the policies related to the operation of the newly introduced equipment. As for the placement of personnel and the organization of time in service (TIS) with respect to the operation of surveillance equipment, there has been a tendency to sustain the conventional practice. Therefore, this study intends to suggest the schemes for facilitating policy improvements in the operation of manpower and security regulations in the field of information for the purpose of introducing a successful next-generation coastal guard system. To do this, the approach of this study was focused on the policies for the operation of the guard system. This is in contrast to previous studies that centered on its equipment and technologies. In addition, how to efficiently operate the guard system was also studied in view of cognitive science by deriving the most efficient time for a person to execute surveillance through the monitor based on the previous studies.

최근 환경보존에 대한 국제적인 관심이 높아지고 있다. 이러한 시류에 따라 ESG경영이 공공부문으로 확장된 SDGs의 성공적인 정책화는 개별 기업 뿐만이 아닌 자본시장과 한 국가의 성패를 가를 키워드로 부상하고 있는 실정이다. 이에 개별 국가에서도 환경과 관련된 다양한 정책을 시행하고 있다. 그 가운데 하나가 환경세를 도입하여 국가정책을 시행하는 것이다. 이와 관련하여 환경오염 행위를 직접 간섭하기보다는 경제적인 유인 원리를 통해서 간접적으로 생산자나 소비자의 행태에 영향을 주어 환경오염을 통제하는 환경세를 활용한 정책이 있다. 본 연구에서는 우리나라에서 시행되고 있는 해양관광지의 환경세의 실태를 파악하고, 정책의 실효성을 검토한다. 더불어 현재 시행되고 있는 제도의 한계점을 확인하여 개선점을 연구하였다. In recent years, many countries are committing to environmental conservation. Following this trend, successful policy implementation of SDGs with ESG management extended to the public sector is emerging as a keyword determining the success or failure of the capital market, countries, and individual companies. Accordingly, many countries are implementing various policies related to the environment. One of them is to implement national policies by introducing environmental taxes. These policies use environmental taxes to control pollution by indirectly influencing the behavior of producers or consumers through economic incentives rather than directly interfering with environmental pollution behavior. This study examines the status of environmental taxes in marine tourism sites in Korea, reviews the effectiveness of such policies, and suggests how to improve them by identifying limitations of the current system.
