Economy of Ukraine is characterized by the rapidly increased level of financial failures at a corporate level. Conditions of doing business in Ukraine become tighter year after year and it should motivate the business owners not only to watch more accurately the state in which their business is but also to introduce new, more precise, more tight systems of crisis management and economic security. The experience shows that in order to stay afloat and not to suffer losses companies should pay more attention to different areas of economic security, such as production potential, financial indicators, logistics, staff, etc. For this purpose companies should use a system of valuation of the most important for their activity indicators and transform their values in an integral one in order to use this assessment in making managerial decisions. Such a valuation is one of the components which the article presents. The article also reveals the key points which characterize crisis management as an integral part of enterprise development and economic security. There are specified the essence and problems of crisis management and proposed the ways of raising the level of economic security of a company based on the example of an industrial and commercial enterprise. The key focus of the enterprise's economic security management is defined as constructive responses to threats from the external environment and, as a result, ensuring stable functioning and effective realization of untapped potential in the future. The current assumption is to explain the scheme of strategic management of an industrial and commercial enterprise and to calculate the methodology of an express assessment of the level of enterprise economic security, taking into account the components of crisis management. To assess the level of economic security of the enterprise, it is proposed to use the method of point assessment, which is based on a multi-level system of indicators, which covers the main areas of the enterprise's activity.

Recently, information security accidents are becoming more advanced as social engineering attacks using new types of malicious codes such as phishing. Organizations have made various efforts to prevent information security incidents, but tend to rely on technical solutions. Nevertheless, not all security incidents can be prevented completely. In order to overcome the limitations of the information security approach that depends on these technologies, many researchers are increasingly interested in People-Centric Security. On the other hand, some researchers have applied behavioral economics to the information security field to understand human behavior and identify the consequences of the behavior. This study is a trend analysis study to grasp the recent research trend applying the concept and idea of behavioral economics to information security. We analyzed the research trends, research themes, research methodology, etc. As a result, the most part of previous research is focused on 'operational security' topics, and in the future, it is required to expand research themes and combine behavioral economics with security behavioral issues to identify frameworks and influencing factors.

Even though much investment to prevent or mitigate damage from information security breaches have been considered, researches on economically rational information security decision-making such as investment, management, etc. are not introduced in Korea. This study analyzes research themes and methodologies of articles presented at the Workshop on the Economics of Information Security (WEIS) for 2002 - 2014. Results of the study can suggest future research topics for researchers, and help make rational information security decision-making for practitioners.

As numerous security breaches on a variety of information assets such as personal information, corporate secrets, computer servers, and networks have occurred, information security has emerged as a critical social issue. However, researches on economically rational information security decision-making have been few. Such researches are especially rare in South Korea where information security is considered to be a discipline of engineers. This study aims to identify the preferred themes and methodologies of information security economics research in the field of information systems by reviewing papers published in Management Information Systems Quarterly (MISQ), Information Systems Research (ISR), European Journal of Information Systems (EJIS), Management Science (MS), and Information and Management (I&M). We hope that the results of the study will be helpful in rational managerial or policy decision-making for practitioners and suggest future research topics for researchers.

The study aims to investigate factors affecting enterprise's satisfaction and loyalty toward the Social Security's online public services, looking at the case of Thanh Hoa province, Vietnam. This study employs samples with 216 enterprises that use online public system of Thanh Hoa province's Social Security. The research model is closely linked to the SERVQUAL model developed by Parasuraman, Zeithaml and Berry (1988). We propose 23 scales that constitute the quality of service, three scales that constitute Customer Satisfaction and three components that constitute Customer Loyalty. This study use the tool of Exploratory Factor Analysis (EFA), Cronbach's Alpha test, Confirm Factor Analysis (CFA) and Structural Equation Modeling (SEM) in order to address the question of satisfaction and loyalty. The result shows that the factor with the most impact is Reliability, next is Capacity of staffs, Tangibles, Attitude of staffs, and the least impacting factor is Empathy; moreover, the results also show that Satisfaction has a strong impact on Customer Loyalty. The findings of this study suggest that Thanh Hoa province's Social Security should: (i) strengthen the reliability of online service system; (ii) build capacity for staffs; (iii) develop the responsiveness of electronic transactions systems; and (iv) improve the empathy of staffs.

This paper aims to not only investigate the nature of financial security and its measurement, but also to compare financial security level in 629 listed companies divided into four different industries (materials, industrials, health care, and consumer goods) before building a theoretical framework and regression models to examine the determinants of financial security. By gathering 2,167 financial statements published in Vietnamese Stock Exchange during eight years from 2012 to 2019, with the support of STATA, the research results indicate that six different internal factors, which are liquidity, profitability, firm size, debt management ratios, asset management ratios, and cash flows, explain 77.7% the change of financial security ratio and 3.4% the change in sustainable growth ratio. Specifically, while firm size has a positive impact on sustainable growth ratio but a negative impact on financial security ratio, deb management and profitability have an insignificant influence on the financial security level. Furthermore, an increase in asset management ratios would result positively in both two dependent variables whereas a rise in sustainable growth and a decline in financial security ratio are expected to witness if there is an increase in cash flows.

This study proposes an alternative to minimize insider-caused security threats that are relatively difficult to control and cause high uncertainty in information security management. Therefore, we investigate the relationship between organizational effort and the security understanding of employees to eventually enhance security compliance intention among employees. We develop a research model and formulate hypotheses on the basis of past findings. Accomplished questionnaires are collected from 526 employees working in organizations where information security policy is being implemented. In addition, we prove the hypotheses using a structural model. After reviewing the structural model, the security knowledge of employees and information security culture are determined to positively influence the security compliance intention of employees. Moreover, top management support, security policy, security visibility, and security education programs are proven to be antecedent factors in establishing a security culture in organizations. The findings of this study could guide organizations in formulating information security strategies to enhance the security compliance intention of employees.

The rise of Industry 5.0 has led to a smarter and more digital way of doing business, but with it comes the issue of user privacy and security. Only when privacy and security issues are addressed, will users be able to transact online with greater peace of mind. Thus, to address the security and privacy problems associated with industry blockchain technology, we propose a privacy protection scheme for online financial transactions based on verifiable ring signatures and blockchain by comparing and combining the unconditional anonymity provided by ring signatures with the high integrity provided by blockchain technology. Firstly, we present an algorithm for verifying ring signature based on distributed key generation, which can ensure the integrity of transaction data. Secondly, by using the block chain technique, we choose the proxy node to send the plaintext message into the block chain, and guarantee the security of the asset transaction. On this basis, the designed scheme is subjected to a security analysis to verify that it is completely anonymous, verifiable and unerasable. The protection of user privacy can be achieved while enabling online transactions. Finally, it is shown that the proposed method is more effective and practical than other similar solutions in performance assessment and simulation. It is proved that the scheme is a safe and efficient online financial transaction ring signature scheme.

The purpose of this study was to investigate the father-child relationship. The final sample for the data analyses included 83 three-year old children and their lathers. The instrument of study was the 'generative fathering'(by Yee et al, 1999). This measurement consisted two areas, first is the father's involvement in child rearing, and second is the responsibility on child rearing. And the child attachment security was observed through Attachment Q-Set(Waters, 1987) in the child's home. The results were following: 1. The mean of the child's attachment security was .33 and the range of attachment security was from -.07 to .79. 2. Father had higher responsibility on rearing, more involved in the child care. 3. The child's attachment security was predicted by the father's involvement in rearing. The father's responsibility didn't show the relationship with the child's attachment security. Especially among the subcategories of involvement, the activity with child had a significant relation to attachment security. So the father's interaction with child was meaningful for the child to develop the internal working model.
