A status of air traffic controller is a government officer and air traffic controllers who work at airport are divided by duty rating and work experience. Abiding by law, rules and regulation, air traffic controllers are working together based on mutual trust. This paper's theoretical background is based on cultural bias theory. The theory divide people group into four groups according to cultural bias such as fatalism, hierarchy, individualism and egalitarianism. A research model was designed how such four cultural bias could affect air traffic controller's risk response in case of emergency or abnormal situation during their work. Depend on empirical research, it was found that air traffic controllers perceived they had been more biased to fatalism than hierarchy. The characteristics of fatalism group are as follows: first of all, they follow rigid rules and regulation. However, they have less self-efficacy compared to other government officers. According to structural equation model, air traffic controller's fatalism had a significant negative effect on organizational royalty. Their royalty, however, had a very significant positive effect on planning response and immediate response.

Network separation is an important policy that Cyber Incident prevent cyber and protect data. Recently, the IT environment is changing in software development, such as remote work, using the cloud, and using open sources. Due to these changes, fintech companies' development productivity and efficiency are lowering due to network separation regulations, and the demand for easing network separation continued. The government revised the regulations electronic financial supervision(hereafter EFS) in response to needs for mitigation of network separation in the IT environment and fintech companies. Some amendments to the EFS, which took effect on 01/01/2023, mitigate network separation only for research and development purposes in cloud environments. If software developed in a cloud development environment is applied to an operating system through a distribution system the existing perimeter-based security model will not satisfaction the network separation conditions. In this Study, we would like to propose a way to maintain the DevOps system in a network separation environment by Using the zero trust security system.

Fraudulence, cheating, and deception can occur in the commercial real estate (CRE) industry, besides the difficulty in searching for and transferring properties while ensuring the operation is processed through an authoritative source in a trusted manner. Nowadays, real estate transactions use neutral third parties to sell land. Indeed, properties can be sold by the owners or third parties multiple times or without a proper deed. Moreover, third parties request a large amount of money to mediate between the seller and buyer. Methods: We propose a new framework that uses a private blockchain network and predefined BPMN instances to enable the fast and easy recording of deeds and their proprietary transfer management controlled by the government. The blockchain allows for multiple verifications of transactions by permitted parties called peers. It promotes transparency, privacy, trust, and commercial competition. Results: We demonstrated the easy adoption of blockchain for land registration and transfer. The paper presents a prototype of the implemented product that follows the proposed framework. Conclusion: The use of Blockchain-based solutions to resolve the current land registration and transfer issues is promising and will contribute to smart cities and digital governance.

In this study, the factors affecting the acceptance intention for level 4-5 of autonomous vehicles were investigated by applying TAM(Technology Acceptance Model). To this end, 332 ordinary persons interested in autonomous vehicle and experienced in driving car were analyzed by using SEM(Structural Equation Modeling). The results showed that self-efficacy and personal innovation had a positive effect on perceived usefulness. On the other hand personal innovation has been shown to have a negative effect on perceived usefulness. Perceived ease of use has a positive effect on perceived usefulness, perceived ease of use and perceived usefulness has a positive effect on acceptance intention. Safety and Privacy has been shown to have a positive effect on trust, trust has a positive effect on acceptance intention. Lastly, autonomous vehicles have a higher impact on their 20s and 30s. The result of this study is expected to be a very useful basic research for the development of target autonomous vehicles, the selection of targets, the direction of corporate marketing strategies, and the preparation of government policies.

The study examines factors that influence shopping intention of online consumers in Vietnam. Studied factors include consumers' attitude, subjective norms, perception of behavioral control, perception of usefulness, perceived risks and trust. The expansion of Theory of Planned Behavior (TPB) and Technology Acceptance Model (TAM) are used as basic theories. We have surveyed people who have experiences on online shopping. There are 836 selected questionnaires that are qualified for data processing. The collected data are analyzed through a process which starts from scale reliability test to exploratory factor analysis (EFA), correlation analysis and regression analysis. The results show that shopping intention of online consumers are positively affected by their attitude, subjective norms, perception of behavioral control, perception of usefulness and trust. In contrast, online shopping intention is negatively affected by the perceived risks that online shopping could bring. Among those factors, the perception of risk is shown to have the strongest influence to online shopping intention. The findings of this study suggest that managers and retailers can apply cash-on-delivery method and design their website with user-friendly interface to enhance online shopping intention of consumers. The Government is also recommended to fulfill the law system to reduce customers' perception of financial risks.

The present paper reviews the development of democracy in the West and Korea. The first part of the paper provide a cultural framework for understanding the development of democracy in West and Korea. In the second part of the paper, an empirical study conducted in Korea will be presented. A survey questionnaire was developed to assess respondents' conception of political participation, political efficacy, trust, leadership, and social relations and it has been administered to national stratified sample in Korea (n=1,000). The results indicate that Korean respondents support the basic ideas of liberal democracy, such as the right to vote, participate in political organization, freedom of speech, and criticize government. At the same time, Korean respondents supported collective values, such as harmonious family life, harmonious social relations, and governmental welfare programs. Although Koreans trusted close ingroup members, such as family members and friends, they were less likely to trust their colleagues and outgroup members and were not likely to trust political and governmental institutions. Moreover, Korean respondents showed a low degree of political participation and efficacy and a high degree of political alienation. As for leadership, Koreans preferred moral and strong leaders. The overall results indicate that in Korea, although the basic ideals of democracy are valued, the method of implementing these ideals is different from the West. Detailed analysis of the results and implications of the study will be presented.

Industrial clusters are geographical concentrations of interconnected companies, specialised suppliers, service providers, firms in related industries, and associated institutions (for example, universities, standard agencies, and trade associations) that combine to create new products and/or services in specific lines of business. At present, the concept of industrial cluster becomes very popular worldwide, policy makers at national, regional and local levels and business people in both forerunner and latecomer countries are keen to implement the cluster concept as an economic development model. Though understanding of clusters and related promoting policies varies from one place to another, the underlying benefits of clusters from collective learning and knowledge spillovers between participating actors strongly attract the attention of these people. In Thailand, a latecomer country in terms of technological catching up, the cluster concept has been used as a means to rectify weakness and fragmentation of its innovation systems. The present Thai government aspires to apply the concept to promote both high-tech manufacturing clusters, services clusters and community-based clusters at the grass-root level. This paper analyses three very different clusters in terms of technological sophistication and business objectives, i.e., hard disk drive, software and chili paste. It portrays their significant actors, the extent of interaction among them and the evolution of the clusters. Though are very dissimilar, common characteristics attributed to qualified success are found. Main driving forces of the three clusters are cluster intermediaries. Forms of these organizations are different from a government research and technology organization (RTO), an industrial association, to a self-organised community-based organization. However, they perform similar functions of stimulating information and knowledge sharing, and building trust among participating firms/individuals in the clusters. Literature in the cluster studies argues that government policies need to be cluster specific. In this case, the best way to design and implement cluster-specific policies is through working closely with intermediaries and strengthening their institutional especially in linking member firms/individuals to other actors in clusters such as universities, government R&D institutes, and financial institutions.

The purpose of this study is to analyze the determinants of the effectiveness in food safety policy, focusing on the perception of consumers. For this, we apply ordered logit analysis using "The Survey on the Attitudes towards Food Safety Policy" data investigated by Ministry of Culture, Sports and Tourism & Ministry of Food, and Drug Safety. According to the results of the analysis, policy literacy has a significant positive impact on the effectiveness of the policy. Trust has a positive impact on the effectiveness of the policy significantly. In addition, the results show that sensitivity has a significant negative impact on the effectiveness perceived by consumers. This study imply that the government should give more information about policies and make an effort to gain trust on food safety policy.
