  • Purpose - As globalization progresses, complexity also increases, and various factors that threaten port functions are emerging. Accordingly, the demand for port security to prevent the crisis and resilience that quickly recovers its original function after the crisis is also increasing in port operations. However, few studies have examined how to ensure the port security and how the resilience affects operation performance of port and sustainability performance as well. So the study aims to find out how port security affects port resilience and port operational performance, and consequently, this two factors affect socioeconomic and environmental sustainability performance respectively and synthetically. Design/methodology - Confirmatory Factor Analysis (CFA) was first performed to determine the validity of the factors of model and hypothesis test was performed using Structural Equation Model (SEM) to analyze the Port Performance Model, which show the perception logic among port security level, port resilience, operation performance, and sustainability performance. In order to empirically analyze this model, total 264 respondents from port security operators, shipping companies in South Korea were surveyed. Findings - As result of SEM, First, port security level positively affected the resilience (H1) and cargo operational performance (H2) but not in both of the sustainability performances (H3, H4). Second, resilience positively affected only cargo operational performance (H5) and socio-economic sustainability performance (H7). Last, cargo operation performance positively affects the both of sustainability performances (H8, H9). Originality/value - It was confirmed that port security could improve cargo operational performance through ensuring port resilience and eventually increase the socio-economic sustainability. Therefore the study implies that careful integration and management of port security, port resilience, and sustainability are required, along with compromise on sustainable development goals in the social, economic, and environmental area among all stakeholders.

  • The article identifies and theoretically substantiates the trends of national resilience in the context of establishing the security of the country and its civilizational subjectivity. The strategy of development of the pedagogical university in the conditions of European integration into the European educational and scientific space based on certain characterological features of the personality of the volunteer in the context of allocation of personal resilience is developed. The analysis of both external and internal challenges and threats to the civilization of the country needs to be understood in the context of economic, socio-political, legal, military-political, spiritual-cultural, educational-scientific and network-information resilience. The concepts of "national resilience" and "national security" are quite close - at first glance, even identical. However, a deeper understanding clarifies the differences: national security is a state of protection of the country identity and its very existence, the realization of its national interests. In turn, resilience is a fairly effective strategy and a fundamental guarantee of national security. At the same time, it is extremely important to understand that both national security as a state and national resilience as a strategy are only means of achieving and developing a strong and humanistic civilizational subjectivity of the country. After all, such subjectivity opens for citizens the opportunity for development, dignified self-realization and a proper life. The restructuring of the volunteer's motivational sphere is due to the dominance of such leading motives, which are focused mainly on maintaining and restoring health, which leads to distorted meaningful life goals: isolation, alienation, passivity, inertia, reduced activity, limited communication, etc. The characteristics of relatively stable human behavior include several primary and secondary properties. The primary (relevant) properties include patience, trust, hope, faith, confidence, determination, perseverance, and love; the secondary - punctuality, neatness, obedience, honesty, loyalty, justice, diligence, thrift, accuracy, conscientiousness, obligation, etc. The restructuring of the volunteer's motivational sphere is due to the dominance of such leading motives, which are focused mainly on maintaining and restoring health, which leads to distorted meaningful life goals: isolation, alienation, passivity, inertia, reduced activity, limited communication, etc. The characteristics of relatively stable human behavior include several primary and secondary properties. The primary (relevant) properties include patience, trust, hope, faith, confidence, determination, perseverance, and love; the secondary - punctuality, neatness, obedience, honesty, loyalty, justice, diligence, thrift, accuracy, conscientiousness, obligation, etc. The use of information and communication technologies in volunteering will contribute to the formation of resilience traits in the structure of personality formation. Directly to the personal traits of resilience should be included methodological competencies, which include methodological knowledge, skills and abilities (ability to define ultimate and intermediate goals, plan, conduct and analyze knowledge, establish and implement interdisciplinary links with disciplines of medical-psychological-pedagogical cycles, etc.). All these competencies form the professional resilience of the volunteer.

  • 사이버 위협이 고도화 및 지능화됨에 따라 사이버 보안 사고를 사전에 완벽하게 예방하는 것은 한계가 있다. 따라서 보안사고 발생을 가정하고 이를 신속하게 탐지하고, 복구할 수 있는 역량이 필요해지고 있다. 이러한 필요성으로 인해 최근 사이버 레질리언스는 중요한 개념으로 부각되고 있으며, 이에 대한 수준을 평가하는 것은 중요하다. 그럼에도 불구하고, 현재 사이버 레질리언스와 관련 평가에 관한 연구는 미흡한 실정이다. 따라서 본 연구에서는 사이버 레질리언스에 대한 이론적 고찰과 전문가 회의를 통해 사이버 레질리언스를 평가할 수 있는 총 22개의 지표를 개발하였다. 개발된 지표는 포커스 그룹 인터뷰를 통해 제안된 지표의 중요도와 실현가능성을 평가하였다. 본 연구는 사이버 레질리언스를 평가함에 있어 의미 있고 유용한 지표를 도출하였다. 이는 향후 사이버 레질리언스 연구의 기반 자료로 활용될 것으로 기대되며, 향후 연구로는 실무적 활용 및 객관화를 위한 정량적 연구를 제안한다.

  • The resilience of a city confronted with a terrorist bomb attack is the background of the paper. The resilience strongly depends on vital infrastructure and the physical protection of people. The protection buildings provide in case of an external explosion is one of the important elements in safety assessment. Besides the aspect of protection, buildings facilitate and enable many functions, e.g., offices, data storage, -handling and -transfer, energy supply, banks, shopping malls etc. When a building is damaged, the loss of functions is directly related to the location, amount of damage and the damage level. At TNO Defence, Security and Safety methods are developed to quantify the resilience of city infrastructure systems (Weerheijm et al. 2007b). In this framework, the dynamic response, damage levels and residual bearing capacity of multi-storey RC buildings is studied. The current paper addresses the aspects of dynamic response and progressive collapse, as well as the proposed method to relate the structural damage to a volume-damage parameter, which can be linked to the loss of functionality. After a general introduction to the research programme and progressive collapse, the study of the dynamic response and damage due to blast loading for a single RC element is described. Shock tube experiments on plates are used as a reference to study the possibilities of engineering methods and an explicit finite element code to quantify the response and residual bearing capacity. Next the dynamic response and progressive collapse of a multi storey RC building is studied numerically, using a number of models. Conclusions are drawn on the ability to predict initial blast damage and progressive collapse. Finally the link between the structural damage of a building and its loss of functionality is described, which is essential input for the envisaged method to quantify the resilience of city infrastructure.

  • 최근 국방 분야를 포함한 국가정보통신망 및 주요 기반시설 등에 대한 해킹 위협이 증가하고 있다. 국방정보시스템은 망분리를 통해 외부로부터의 위협에 대응하고 있으나, 해킹 성공시 전 평시 군사작전에 큰 영향을 미치게 된다. 오늘날 사이버 공격과 위협은 예측 불가능한 수준으로 높아지고 있어 해킹 위협을 완전히 차단하고 예방하는 것은 현실적으로 불가능하다. 따라서 본 연구에서는 국방정보시스템의 사이버 공격 징후가 예상되거나 발생했을 경우 신속한 대응 및 시스템의 생존성을 보장하고 지속성을 유지할 수 있는 능력인 '사이버복원력(Cyber Resilience)'의 수준을 평가할 수 있는 성숙도모델을 제시하였다. 제시된 성숙도모델을 통해 국방정보시스템의 사이버복원력 수준을 평가하고 부족한 분야를 식별 및 보완함으로써 국방정보시스템의 사이버보안 수준을 향상시키는데 기여할 수 있을 것으로 기대된다.

  • The article contains an overview of the results of recent research by think tanks in different countries, devoted to the analysis of economic resilience factors in the Covid-19 crisis and the development of recommendations for improving preparedness for the next crises. The authors consider and propose a theoretical framework for the concept of the resilience of economic systems. The impact of the COVID-19 crisis on national economies is analyzed. Factors explaining the different cability of economic systems to withstand shock in the short and long term are identified. The reactions of market participants and national governments to the crisis are assessed. It is shown how the COVID-19 crisis has affected the digital transformation of economic systems, and how digital transformation helps to increase the resilience of national economies so that the latter can emerge from the crisis even stronger.

  • The purpose of this paper is to consider the expansion of non-traditional security threats and the national-level response to the emergence of emerging security threats in ultra-uncertain VUCA situations. As a major research method for better analysis, the theoretical approach was referred to papers published in books and academic journals, and technical and current affairs data were studied through the Internet and literature research. The instability and uncertainty of the international order and security environment in the 21st century brought about a change in the security paradigm. Human security emerged as the protection target of security was expanded to individual humans, and emerging security was emerging as the security area expanded. Emerging security threatsthat have different characteristicsfrom traditionalsecurity threats are expressed in various ways, such as cyber threats, new infectious disease threats, terrorist threats, and abnormal climate threats. First, the policy and strategic response to respond to emerging security threats is integrated national crisis management based on artificial intelligence applying the concept of Foresight. Second, it is to establish network-based national crisis management smart governance. Third, it is to maintain the agile resilience of the concept of Agilience. Fourth, an integrated response system that integrates national power elements and national defense elements should be established.
