Safety Critical Maritime Infrastructure (SCMI) systems are vulnerable to diverse risks in their challenging field of operations due to their interactions and interdependence. In addition, the multiplicity of stakeholders in these systems and the complex operational scenarios are often associated with a high level of uncertainty because they usually operate in a dynamic environment in which the boundaries of safety are pushed, leading to the disruption of operations. Therefore, the safety of these systems is very important to ensuring resilience of their operations. This research is focus on the background analysis of SCMI systems. This includes operational processes of SCMI systems, security threats and estimates of economic damage to the system, resilience engineering literature relevant to maritime operations; regulatory overview including risk governance of the systems, lessons learnt from major accidents and a concluding remark is drawn.

Epidemiological Characteristics

Chickenpox is an urgent problem, as it is widely spread with a high level of morbidity and an increasing share in the structure of the General infectious pathology with significant economic damage. The aim of the study is to study the epidemiological and clinical features of chickenpox in adults hospitalized in Krai government-owned publicy funded health care institution «City clinical hospital No. 5, Barnaul» for the period 2008‑2018. Content analysis included statistical reporting forms No. 2 of Federal state statistical supervision «Data on infectious and parasitic diseases» in the city of Barnaul during the period 2008‑2018 of medical archival documents adult infectious Department Krai government-owned publicy funded health care institution «City clinical hospital №5, Barnaul» for the same period. Data processing was performed using calculation of intensive and extensive indicators, calculation of the arithmetic mean (X) and standard error of the average (m). Calculations were made using the STATISTICA-10 program. Consistently high rates were recorded, with an average of 64.32 ± 3.46 per 100,000 population. The percentage of hospitalized adults averaged 18.5% during the study period. Adults aged 18‑30 were more likely to be admitted to the hospital (90.3%); 41.6% were students. Adults with moderate severity were hospitalized more often (70.6%); 7 patients (1.3%) had complications: aphthous stomatitis (3 cases), pustulosis (2 cases), and pneumonia (2 cases). Patients with severe severity of the disease accounted for 2.4%, the premorbid background was burdened in 48% (HIV infection, tuberculosis). In 35% of patients with severe severity, the final diagnosis of Herpes zoster was made, all patients older than 40 years, stayed in the hospital for 20‑25 days.

Protection motivation theory (PMT) is one of the most commonly used theories to examine information security behaviors. Our systematic review of the application of PMT in information systems (IS) security and the comparison with its application for decades in psychology identified five categories of important issues that have not yet been examined in IS security research. Discussing these issues in terms of why they are relevant and important for IS security, and to what extent IS research has not considered them, offers new research opportunities associated with the study of PMT and IS security threats. We suggest how future studies can approach each of the open issues to provide a new road map for quantitative and qualitative IS scholars.

Abstract Background The African Union’s High-Level Panel on Emerging Technologies identified gene drive mosquitoes as a priority technology for malaria elimination. The first field trials are expected in 5–10 years in Uganda, Mali or Burkina Faso. In preparation, regional and international actors are developing risk governance guidelines which will delineate the framework for identifying and evaluating risks. Scientists and bioethicists have called for African stakeholder involvement in these developments, arguing the knowledge and perspectives of those people living in malaria-afflicted countries is currently missing. However, few African stakeholders have been involved to date, leaving a knowledge gap about the local social-cultural as well as ecological context in which gene drive mosquitoes will be tested and deployed. This study investigates and analyses Ugandan stakeholders’ hopes and concerns about gene drive mosquitoes for malaria control and explores the new directions needed for risk governance. Methods This qualitative study draws on 19 in-depth semi-structured interviews with Ugandan stakeholders in 2019. It explores their hopes for the technology and the risks they believed pertinent. Coding began at a workshop and continued through thematic analysis. Results Participants’ hopes and concerns for gene drive mosquitoes to address malaria fell into three themes: (1) ability of gene drive mosquitoes to prevent malaria infection; (2) impacts of gene drive testing and deployment; and, (3) governance. Stakeholder hopes fell almost exclusively into the first theme while concerns were spread across all three. The study demonstrates that local stakeholders are able and willing to contribute relevant and important knowledge to the development of risk frameworks. Conclusions International processes can provide high-level guidelines, but risk decision-making must be grounded in the local context if it is to be robust, meaningful and legitimate. Decisions about whether or not to release gene drive mosquitoes as part of a malaria control programme will need to consider the assessment of both the risks and the benefits of gene drive mosquitoes within a particular social, political, ecological, and technological context. Just as with risks, benefits—and importantly, the conditions that are necessary to realize them—must be identified and debated in Uganda and its neighbouring countries.

Abstract Directing groups of unmanned air vehicles (UAVs) is a task that typically requires the full attention of several operators. This can be prohibitive in situations where an operator must pay attention to their surroundings. In this paper we present a gesture device that assists operators in commanding UAVs in focus-constrained environments. The operator influences the UAVs’ behavior by using intuitive hand gesture movements. Gestures are captured using an accelerometer and gyroscope and then classified using a logistic regression model. Ten gestures were chosen to provide behaviors for a group of fixed-wing UAVs. These behaviors specified various searching, following, and tracking patterns that could be used in a dynamic environment. A novel variant of the Monte Carlo Tree Search algorithm was developed to autonomously plan the paths of the cooperating UAVs. These autonomy algorithms were executed when their corresponding gesture was recognized by the gesture device. The gesture device was trained to classify the ten gestures and accurately identified them 95% of the time. Each of the behaviors associated with the gestures was tested in hardware-in-the-loop simulations and the ability to dynamically switch between them was demonstrated. The results show that the system can be used as a natural interface to assist an operator in directing a fleet of UAVs. Article highlights A gesture device was created that enables operators to command a group of UAVs in focus-constrained environments. Each gesture triggers high-level commands that direct a UAV group to execute complex behaviors. Software simulations and hardware-in-the-loop testing shows the device is effective in directing UAV groups.

Abstract Background: Organisations nowadays operate in a very dynamic environment, and therefore, their ability of continuously adjusting the strategic plan to the new conditions is a must for achieving their strategic objectives. BSC is a well-known methodology for measuring performances enabling organizations to learn how well they are doing. In this paper, “BSC for IS” will be proposed in order to measure the IS impact on the achievement of organizations’ business goals. Objectives: The objective of this paper is to present the original procedure which is used to enhance the BSC methodology in planning the optimal targets of IS performances value in order to maximize the organization's effectiveness. Methods/Approach: The method used in this paper is the quantitative methodology - linear programming. In the case study, linear programming is used for optimizing organization’s strategic performance. Results: Results are shown on the example of a case study national park. An optimal performance value for the strategic objective has been calculated, as well as an optimal performance value for each DO (derived objective). Results are calculated in Excel, using Solver Add-in. Conclusions: The presentation of methodology through the case study of a national park shows that this methodology, though it requires a high level of formalisation, provides a very transparent performance calculation.

It is impossible to ensure sustainable business development without solving the maintenance of labor resources issues that are included in the manufacturing process, as well as involving new employees to increase labor potential. The company can effectively confront the new challenges by attracting highly qualified employees for whom a high level of safety is important. Therefore, an important direction of sustainable business development is to increase the level of safety and create a comfortable working environment and optimize working processes to increase the efficiency of production activities, as well as prepare for the challenges that may arise in the process of company development. The article analyzes the statistics and structure of the socio-economic damage to business due to unsatisfactory working conditions and a high level of injuries on the example of the machine-building sector, and also considers aspects of maintenance of labor resources and ways to involve additional labor resources to ensure sustainable manufacturing development. Based on conducted analysis, an algorithm of implementation of managerial decisions was developed, aimed at ensuring the safety of personnel who carry out the work activities at the workplace, taking into account the modern concept of the “green workplace”. Involvement in the working process of additional labor reserves is carried out by creating favorable working conditions, assessing the special needs and level of ability of workers for optimization of working processes and increasing their efficiency.

Brucellosis is a particularly dangerous and socially significant infection that causes considerable economic damage and leads to a high level of patients’ disability (Vershilova P. A., 1961, Beklemishev N. D., 1965). Brucellosis is a global problem for medical and veterinary health services (Corbel M. J., 1997, Boschiroli M. L., 2001). According to the information of WHO Joint Expert Committee on Brucellosis (1986), this disease is registered among animals in 155 countries around the world. Mostly Brucellosis is spread in the Mediterranean countries, Asia Minor, South and South-East Asia, Africa, Central and South America (Sauret I. M. E., 2002; Ergonul O. E. A., 2004; Karabay O. E. A., 2004; Getinkaua Z. E. A., 2005; Alim A., Tomul Z. D., 2005; Onishchenko G. G., 2005) These indices are ten times higher in countries of Central Asia. The registered cases of this disease here are compounded 116 cases per 1 million people in Kazakhstan and 362 in Kyrgyzstan. In Uzbekistan, there are 18 cases per 1 million people. In the Russian Federation there are 4.1 cases per 1 million people, Greece – 21 cases, Germany and the United Kingdom – 0.3 cases.
