Abstract—The rapid development of web-based systems in the digital transformation era has led to a dramatic increase in the number and the severity of cyber-attacks. Current attack prevention solutions such as system monitoring, security testing and assessment are installed after the system has been deployed, thus requiring more cost and manpower. In that context, the need to assess cyber security risks before the deployment of web-based systems becomes increasingly urgent. This paper introduces a cyber security risk assessment mechanism for web-based systems before deployment. We use the Bayesian network to analyze and quantify the cyber security risks posed by threats to the deployment components of a website. First, the deployment components of potential website deployment scenarios are considered assets, so that their properties are mapped to specific vulnerabilities or threats. Next, the vulnerabilities or threats of each deployment component will be assessed according to the considered risk criteria in specific steps of a deployment process. The risk assessment results for deployment components are aggregated into the risk assessment results for their composed deployment scenario. Based on these results, administrators can compare and choose the least risky deployment scenario. Tóm tắt—Sự phát triển mạnh mẽ của các hệ thống trên nền tảng web trong công cuộc chuyển đổi số kéo theo sự gia tăng nhanh chóng về số lượng và mức độ nguy hiểm của các cuộc tấn công mạng. Các giải pháp phòng chống tấn công hiện nay như theo dõi hoạt động hệ thống, kiểm tra và đánh giá an toàn thông tin mạng được thực hiện khi hệ thống đã được triển khai, do đó đòi hỏi chi phí và nhân lực thực hiện lớn. Trong bối cảnh đó, nhu cầu đánh giá rủi ro an toàn thông tin mạng cho các hệ thống website trước khi triển khai thực tế trở nên cấp thiết. Bài báo này giới thiệu một cơ chế đánh giá rủi ro an toàn thông tin mạng cho các hệ thống website trước khi triển khai thực tế. Chúng tôi sử dụng mạng Bayes để phân tích và định lượng rủi ro về an toàn thông tin do các nguồn đe dọa khác nhau gây ra trên các thành phần triển khai của một website. Đầu tiên, các thành phần triển khai của các kịch bản triển khai website tiềm năng được mô hình hoá dưới dạng các tài sản, sao cho các thuộc tính của chúng đều được ánh xạ với các điểm yếu hoặc nguy cơ cụ thể. Tiếp đó, các điểm yếu, nguy cơ của từng thành phần triển khai sẽ được đánh giá theo các tiêu chí rủi ro đang xét tại mỗi thời điểm cụ thể trong quy trình triển khai. Kết quả đánh giá của các thành phần triển khai được tập hợp lại thành kết quả đánh giá hệ thống trong một kịch bản cụ thể. Căn cứ vào kết quả đánh giá rủi ro, người quản trị có thể so sánh các kịch bản triển khai tiềm năng với nhau để lựa chọn kịch bản triển khai ít rủi ro nhất.

In view of the ambiguity and randomness of the assessment of earthquake scene rescue performance, this paper proposes an integrated assessment method considering quantitative and qualitative influencing factors from three levels: search, rescue and medical treatment. Firstly, this study constructs an assessment index system of rescue performance at the earthquake scene based on the International Search and Rescue Advisory Group (INSARAG) guidelines set by International Search and Response. Secondly, the subjective weights and objective weights of each index were calculated using the hierarchical analysis process (AHP) and cloud model, respectively. The comprehensive weights were calculated using weighted analysis, and the performance assessment results were visually expressed by cloud model images. Finally, the study was applied to an earthquake rescue case with an initial assessment of 4.0065, and its performance was improved by 4.36% when the rescue process was optimized. The assessment results show that earthquake rescue performance can be estimated, and the rationality and effectiveness of the method was validated.

One year after the spread of the pandemic, we analyzed the assessment results of the quality documentation submitted to the Clinical Trials Office of the Italian Medicines Agency as part of the request for authorization of clinical trials with a COVID-19 indication. In this article, we report the classification of the documentation type, an overview of the assessment results, and the related issues focusing on the most frequently detected ones. Relevant data regarding the Investigational Medicinal Products (IMPs) tested in COVID-19 clinical trials and their quality profiles are provided in the perspective of increasing transparency and availability of information. Some criticalities that have been exacerbated by the management of clinical trials during the emergency period are highlighted. Results confirm that IMPs tested in authorized COVID-19 clinical trials are developed in agreement with the same legal requirements for quality, safety, and efficacy as for any other medicinal product in the European Union (EU). The same strong regulatory framework applies, and there is no lowering in the safety profile due to the pandemic; authorized IMPs meet the highest standards of quality. The regulatory network should capitalize on lessons learned from the emergency setting. Some take-home messages are provided that could support the regulatory framework to expand its boundaries by innovating and evolving even though remaining strong and effective.

The article presents the results of petroleum potential quantitative forecast of the Toarcian, Pliensbachian and Hettangian-Sinemurian regional reservoirs of Lower Jurassic deep-buried deposits within Yenisei-Khatanga and adjacent territories of the Gydan petroleum regions based on models of structure and reconstructed conditions of formation for each of the noted reservoirs and their components – permeable complexes and fluid seals, developed earlier by the authors of this article. Tectonic, lithological-facies and geochemical criteria for assessing the oil-and-gas bearing prospects of reservoirs are described. The methodology and the petroleum potential quantitative assessment results for regional reservoirs with attached maps of petroleum potential of each reservoir are considered. The structure of hydrocarbon resources (HC) is given: the distribution of initial total hydrocarbon resources by phase composition, regional reservoirs and oil and gas-bearing areas.

<p>The National Certificate of Educational Achievement (NCEA) is New Zealand’s main national qualification for senior secondary school students. A key feature of NCEA is that it allows for more than half of students’ final NCEA grades to be assessed by teachers during the school year through school-based assessment, known as internal assessment. This key role of teachers in awarding qualifications is likely to have an impact on their conceptions of assessment, conceptions of assessment that are not necessarily fixed. In turn, conceptions can influence teaching practice and are likely to have an impact on how teachers implement internal assessment.   This thesis uses an explanatory sequential, mixed methods design to investigate a group of economics and accounting teachers’ conceptions of assessment, their practices in relation to NCEA internally-assessed standards, and the influences on those practices. G.T.L. Brown’s (2006) Teachers’ Conception of Assessment Abridged (TCoAIIIA) Inventory was used to investigate the participants’ conceptions of assessment, and interviews were conducted to probe their internal assessment practices and reasons for those practices.  The quantitative data were analysed using confirmatory factor analysis which showed an inadmissible fit to G.T.L. Brown’s (2006) model. A subsequent exploratory factor analysis revealed partly similar and partly different dimensions in the data, compared with those previously reported in other studies using the TCoAIIIA. Qualitative data were thematically analysed and when the qualitative and quantitative data were considered together, greater similarities with G.T.L. Brown’s model emerged. Participants revealed four overarching conceptions of assessment: assessment is for learning; assessment is for qualifications; assessment is for accountability; and assessment is detrimental. This finding has reinforced the view that teachers’ conceptions of assessment are ecologically rational in that a distinct conception that probably relates to the role participants play in assessing for NCEA emerged.   Despite this role, participants also adhered to the conception that a primary function of assessment is to improve students’ learning; furthermore, they did not support the use of assessment results as a measure of school quality. An implication of this finding is a belief that promoting a school-accountability use of assessment results is likely to be counter-productive to students’ learning.   The qualitative findings revealed a complex set of beliefs and practices towards implementing the internally-assessed component of NCEA, and that beliefs were only one influence on teachers’ internal assessment practices. Teachers had to balance their beliefs with the systemic realities of NCEA and their school’s policy requirements, and articulated a tension between the improvement and accountability conceptions of assessment. Moderation processes, procedures and policy encouraged teachers into a cycle of safe rather than innovative internal assessment practice, which means that the original vision for NCEA internal assessment is yet to be realised. There are implications of this finding for professional development, leadership of assessment, and initial teacher education.   One such implication is a requirement for professional development that would provide teachers with successful, innovative internal assessment practices, rather than the present approach which focusses on the reliability of marking. Schools’ management needs to take a greater role in leading and encouraging pedagogically sound internal assessment, rather than focussing primarily on agreement rates with NZQA moderators. Initial teacher educators could also introduce student teachers to effective internal assessment practices and to encourage such practices. In addition, attempts to change teachers’ assessment practices need to consider existing conceptions of assessment because beliefs have an impact on practices and may need to be challenged. While there is debate about whether beliefs change practice or vice versa, one cannot be changed without considering the other.</p>
