  • A new prototype software package has been developed by integrating two existing programs designed to predict and maneuver chemical and nuclear disasters in order to set up a response system for dealing with the combined two disasters. The protype is designed to be mainly used by civil defence officers, together with an identification of 625 scenarios of chemical and nuclear disasters. The package is expected to contribute to upgrade a more systematic regional public protection plan for chemical and nuclear disasters. In addition, it enables all relevant local divisions to share disaster information in real time, resulting in a minimization of possible fatal damages.

  • This article defines the process of formation of anti-corruption consciousness as one of the areas of interaction between public authorities and civil society institutions. It is concluded that the implementation of the state anti-corruption policy in Ukraine may be more promising if the institutions of civil society are actively involved. The degree of citizen engagement can be increased by increasing social trust, as well as by increasing the level of political and legal education and culture. Particular attention should be paid to the organization of public control and monitoring of the activities of public authorities, impartial coverage of information on the fight against corruption in the media, as well as the joint conduct of an information and educational campaign and the promotion of the formation of anti-corruption consciousness among a large number of citizens.

  • 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.

  • In the present study, the finite strip analysis of a box girder to simulate a ship's hull model is carried out to investigate its inelastic post-buckling behavior and to predict its ultimate flexural strength. Residual stresses and initial geometrical imperfections are both considered in the combined material and geometrical nonlinear analysis. The von-Mises yield criterion and the Prandtl-Reuss flow theory of plasticity are applied in modeling the elasto-plastic behavior of material. The Newton-Raphson iterative process is also employed in the analysis to achieve convergence. The numerical results agree well with the experimental data. The effects of some material and geometrical parameters on the ultimate strength of the structure are also investigated.

  • Structural design of a composite beam is influenced by two main factors, strength and ductility. For the design to be effective for a composite beam, say an RC slab and a steel I beam, the shear strength of the composite beam and ductility have to carefully estimate with the help of displacements between the two members. In this investigation the shear strengths of steel-concrete composite beams was analyzed based on the respective variable parameters. The methodology used by ANFIS (Adaptive Neuro Fuzzy Inference System) has been adopted for this purpose. The detection of the predominant factors affecting the shear strength steel-concrete composite beam was achieved by use of ANFIS process for variable selection. The results show that concrete compression strength has the highest influence on the shear strength capacity of composite beam.

  • Section 39(5) of Marine Insurance Act 1906 concerns the case where with the privity of the assured, the ship is sent to sea in an unseaworthy state. The underwriters argue that the assured had"blind-eye knowledge" of the particular respect in which the ship was unseaworthy. Blind-eye knowledge requires a conscious reason for blinding the eye. There must be at least a suspicion of a truth about which one do not want to know and which one refuse to investigate. What has caused greater difficulty is the broad provision in s.17 which appears to be unlimited in its scope. The expression "utmost good faith" appears to derive from the idea of uberrimae fidei, words which indeed appear in the sidenote. The concept of uberrima fides does not appear to have derived from civil law and it has been regarded as unnecessary in civilian systems. S.17 raises many questions. But only two of them are critical to the decision of the present appeal-the fraudulent claim question and the litigation question. It is however necessary to discuss them in the context of a consideration of the problematic character of s.17. In the Star Sea Case, for the defendants to succeed in their defence under this part of the case the defendants have to show that claim was made fraudulently. They have failed to obtain a finding of fraud. It is not enough that until part of the way through the trial the owners failed to disclose to the defendants would have wished to see in order to provide them with some, albeit inadequate, evidential support for their alleged defence under s.39(5). The defence under s.17 fails. The Purpose of this work is to analyze the Star Sea Case, and to explore problems of the MIA relating to the judgement of this case.

  • Purpose: This paper aims to determine features of the relationship between human development, tourism and national brand. Research design, data and methodology: ranking indicators, cluster analysis, K means method, correlation analysis. Results: The analysis covers data for 95 countries for 2019. The number of countries is justified by the availability of comparable data for calculations. A direct relationship between the indicators for the entire sample has been revealed in the result of the correlation analysis. However, this relationship has not been confirmed for the groups of countries that were formed through the cluster analysis. Spearman Rank Order and Kendall Tau Correlations have been calculated for the five obtained clusters. In two of the five clusters, the relationship between the indicators has not been found. A strong negative link between all the indicators has been detected in the cluster with average index values. A strong positive link between TTCI and BSI has been revealed in the group of countries with the best index values. A strong positive link between TTCI and HDI has been found in the group of countries with the worst index values. Conclusions: The analysis demonstrates that there is a relationship between BSI, TTCI and HDI, and while this link is observed for the sample as a whole, it is not homogeneous for groups of countries.

  • In spite of international efforts to control nuclear weapons and chemical, biological, and radiological (CBR) weapons, North Korea obtains and sells CBR weapons illegally. As a result, the worldwide threat of CBR weapons is increasing. Unfortunately, civil defense education and training for CBR weapons have not been adopted for real situations because of the long period of absence of an actual combat. In this study, virtual training scenarios that are applied to the simulation were made in 5 steps to cope with CBR situations. These scenarios are expected to have three effects. First, trainings can be improved with experience and education. Second, the problems and health hazards of CBR weapons and supplies can be solved with CBR virtual training simulation experience. Finally, corresponding effects can be recognized and predicted in real situations through roles and mission procedures of simulation scenario.

  • Reinforced concrete (RC) structures are likely to experience damage when subjected to earthquakes. Damage index (DI) has been recognised as an advanced tool of quantitatively expressing the extent of damage in such structures. Last 30 years have seen many concepts for DI proposed in order to calibrate the observed levels of damage. The current research briefly reviews all available concepts and investigates their relative merits and limitations with a view to proposing a new concept based on residual deformation. Currently available DIs are classified into two broad categories - non-cumulative DI and cumulative DI. Non-cumulative DIs do not include the effects of cyclic loading, whilst the cumulative concepts produce more rational indication of the level of damage in case of earthquake excitations. Ideally, a DI should vary within a scale of 0 to 1 with 0 representing the state of elastic response, and 1 referring to the state of total collapse. Some of the available DIs do not satisfy these criteria. A new DI based on energy is proposed herein and its performances, both for static and for cyclic loadings, are compared with those obtained using the most widely accepted DI in literature. The proposed DI demonstrates a rational way to predict the extent of damage for a number of case studies. More research is encouraged to address some identified issues.
