In order to improve participation and quick decision-making in an emergency, the Voluntary Participation Program was recommended in this study for effective management of Civil Defense. The problems in the Law and Administration group and Forced Education by Mobilization system were analyzed through actual conditions of Civil Defense management and participation. In order to improve these problems, cases such as "Extension of Participation Methods", "Cooperation Activities with Civil Groups", "Usage of Community Information" were studied. Based on the investigation results, domestic applicability was recommended.

The role of Unmanned Aircraft Vehicles(UAVs) has been increasing significantly in both military and civilian operations. Many complex systems, such as UAVs, are difficult to model accurately because they exhibit nonlinearity and show variations with time. Therefore, the control system must address the issues of uncertainty, nonlinearity, and complexity. Hence, identification of the mathematical model is an important process in controller design. In this paper, attitude dynamics identification of UAV is investigated. Using the flight data, nonlinear state space model for attitude dynamics of UAV is derived and verified. Real time simulation results show that the model dynamics match experimental data.

In this paper, we explain Production Liability(PL) law and research method of protection and defence of PL law. In introduction, we give some examples of PL law In main issue, we explain more detail PL law. We survey several country PL law, specially U.S.A., EU, Japan whose are deeply related with us as important export country We discuss our country PL status, our country don't legislate PL law until now We have consumer protection law(소비자보호법) which is weaker than PL law but stronger than civil law(민법), We believe that PL law will be legislated within not long time. At last we discuss protection and defence of PL law inside of company and outside of company as PL insurance.

This paper describes the application method of systems engineering for systems of systems and addressed the evolution in approach as organizations have evolved from standalone platform providers to architect of SoS. There is an increasing need to perform Systems of Systems Engineering(SoSE) in a global environment This has stimulated the development of new, innovative SoSE approaches that surpass current military and industry state-of-the-art systems engineering processes. The simple scaling of the former process was ineffective in dealing with global distributed large-scale integration efforts of network-centric systems of systems. A new SoSE process has been developed which is a significant breakthrough in the development of large complex systems and net-centric systems of systems. The SoSE process provides a complete, detailed and systematic development approach for military and civil SoS. In this point of view, this paper analyzes functionally the architecture framework, process and integrated verification & validation of SoSE. From results of this analysis, perspectives on the application of SoSE suitable for Korea aquisition environment are presented.

The snow cornice mass on the formation zone had triggered avalanches which led to the loss of human life and property. Snow cornice is formed due to flow separation on the leeward side. Effect of lee slope is more prominent in the formation of snow cornices as compared to the windward slope. The analysis of wind flow pattern has been carried out to evaluate the performance of a jet roof. Computational Fluid Dynamics (CFD) analysis of wind flow over a 2D hill model was carried out using RNG based k-∈ turbulence models available in ANSYS Fluent. Effect of varying leeward hill slope (1:2 to 1:6) on flow separation for the given windward slope was observed and a critical slope of 1:4 was found at which the separation zone ceased to exist. The modification of wind flow over a hill due to the installation of jet roof was simulated. It was observed that jet roof had significantly modified the wind flow pattern around hill ridgeline and ultimately snow cornice formation had mitigated. The results of the wind flow pattern were validated with the wind data collected at the experimental site, Banihal Top (Jammu and Kashmir, India). The wind flow simulation over the hill and mitigation of cornice formation by the jet roof has been explained in the present paper.

The purpose of this study is to suggest improvement direction of the delivery system through researching the information accepter' recognition and use about warning delivery system. According to the survey, they listen to civil defence alert broadcasting on mass media more than personal media. The frequency of alert broadcasting is significantly very low and they listen to it below 5 times in a year. Also, nearly one in four people says its siren and contents are indistinct. Alert broadcasting's siren shows less memory retrieval and sorting capability than others and the result shows that they will act based on the broadcasting instead of reacting to prior knowledge in real situations. Finally, the result shows that improving public awareness through education and publicity more than social system buildup is important in civil defence alert system.

A forecast foresight of the conditions for the development of educational affairs in the Information Society of Ukraine is presented, taking into account changes in the technique, technologies, and the socio-social sphere. Unresolved problems in Ukraine regarding the modernization and improvement of the education system by means of informatization are highlighted. The need for further improvement of Ukrainian education by means of informatization is noted. Formulated the main goal of future education. The necessary conditions for the successful development of future education are highlighted. The role and place of the key figure of the teacher in the education of the future is determined. The article highlights the theoretical and philosophical foundations of professional subjectivity of the future specialist. Recently, the world's pedagogical thought has increasingly focused on how to build an educational process so that it brings a sense of happiness to all its participants. It is believed that this is a new management philosophy in general, although its origins are in ancient Greek sources, which claim that only a happy life has meaning and value. It is found out that the professional subjectivity of a specialist is an important professionally significant quality of the individual, which provides a purposeful and optimal implementation of their mental, personal resources for solving professional and life problems, which is manifested in the desire for self-definition, self-determination, self-regulation and self-improvement in professional activities taking into account the information society. The structure of this phenomenon is shown.

This study is to select the areas to ensure stream space or to implement flood defence measures according to flood frequencies by classifying the stream segment using river bed slope in Mangyeong river. The analysis result for each stream segment showed that the variation of flood inundation area was small in upper stream catchment. But in the lower stream area, the inundation area became larger greatly according to the increase of flood return period. This study classified the catchment of each steam segment as the region of ensuring stream space (ESS), below 10% residential area ratio, and the region of reinforcing flood defence (RFD), over 10% residential area ratio. The analysis results showed that the lower stream area included more RFD regions than upper stream area, and the upper stream area included more ESS regions than lower stream area. In future study, the regions stream spaces can be ensured will be analyzed considering the past stream morphology and the positions of wetlands.
