More emphasis has recently been put on the strategic application of IT, the linkage and integration between information system, and business process for value increase of a company's business. Thus, it is high time to redefine the concept of IT governance in order to effectively manage various IT services and assets. However, less attention has been paid to the practical study of domestic firms, compared to in the academic and industrial level. In this study, the current situation of IT governance setup and various factors for future development will be examined by a case study to explore activities, types, and determinants of decision making process that companies are currently conducting regarding IT governance. For the purpose of comparative analysis, two large enterprises were chosen with similar size of sales and high investment rate for IT within the same industry, and in-depth analysis was conducted based on the interviews of the concerned parties and in-house materials, from the perspective of structure, process, and relational mechanism. By the case study on IT governance of company 'A' and 'B', decision making mechanism and factors will be analyzed, which will indicate detailed characteristics of each decision-making field and its components for general application. By doing so, it is expected to be used as reference in building IT governance that fits the environment of a firm in the future.

The current transportation regime is largely based on two alternatives: (1) fixed route public transit, and (2) private ownership of internal combustion engine (ICE) powered vehicles per households. This paper analyzes one possible transportation alternative, Micro Electric Vehicles or MEVs, and compares with the ICE vehicles in terms of social, economic and environmental benefits, especially emphasizing its environmental advantage over ICE vehicles for future sustainability. While some representative models of MEVs exist in a limited market capacity, but global technical standards are generally insufficient and non-homogenous across nations, which restricts the development of the proposed transportation sector. The focus of this paper is to analyze the characteristics and potential benefits of MEVs in economical and environmental perspectives, including development status and technical standards, with a particular focus in the E.U., the U.S., Japan, and Korea. Based on the data of analysis, this paper aims to derive and propose a cooperative and adaptive global policy framework designed to speed up adoption and expansion of the global MEV market, including passenger and utility vehicles. We propose MEV to be a new mobility segment in the global transportation market because of their advantage in environmental impact, sustainability, overall cost of ownership, and safety.

Globalization of economy brings both opportunities and threats especially for companies in developing countries such as Korea. Globalization is an opportunity because it may expand the size of market for the company where globalization brings a threat for developing global competitiveness. If the company has already built competitive advantage in its business domain, the company can easily transfer market growth to profit improvement. However, if the company has not developed competitive advantage, globalization of economy will give a serious threat for the survivor of the company. The company might lose its own domestic market share. For the less famous brand of product or company name, international expansion is a challenging strategy. The study evaluated organizational performance of companies that try international expansion by utilizing Miles and Snow's strategy typology. We clustered organizations based on their strategy typology (prospector, analyzer, defender, and reactor) in view of the level of product diversification, new product development instances, level of localization, and autonomy of foreign subsidiary. With the strategy typology, we evaluated international strategy in view of product competitiveness, marketing strategy, human resource strategy, and organizational strategy. The regression result demonstrates that the performance of the company is significantly higher when the company employs prospector strategy. We also found out that product quality and emphasis for developed countries in international expansion are the most important factors for success.

Background: Infection prevention and control (IPC) to manage healthcare-associated infection (HCAI) has emerged as one of the most significant public health issues in Korea. The purpose of this study is to draw implications in IPC policies by analyzing the context, process, and major actors in policy development and comparatively analyzing IPC policy contents of Korea with three other countries. Additionally, IPC policies were analyzed in the context of coronavirus disease 2019 (COVID-19) to provide implications for future pandemics and HCAI events. Methods: This study incorporates a qualitative approach based on document and content analysis, applying codes and thematic categorization. IPC policy contents are comparatively analyzed by adopting the concept model, developed by the World Health Organization, which consists of core components of IPC structure at the national and facility level. Results: National IPC policies were developed within a complex social and political context, through the involvement of various stakeholders. IPC policies in Korea place a high emphasis on establishing IPC programs and built environments in healthcare facilities, whereas there were potentials for improvement in policies involving patients and promoting a safety culture. IPC policies, which currently focus on general hospitals and certain functions of hospitals, should further be expanded to target all healthcare facilities and functions, to ensure more efficient and sustainable IPC responses in the current and future disease outbreaks. Conclusion: IPC is a complex policy arena and lessons learned from the analysis of existing policies in the context of COVID-19 should provide valuable strategic implications for future policies.

The global economy and the air transport business have been affected since the spread of the COVID-19 pandemic. As countries tighten restrictions on international movements, the growing emphasis on air cargo puts pressure on airports to maintain and upgrade their cargo policies, facilities, and operations. Hence, ensuring the competitiveness of cargo airports becomes pivotal for airports survival under the volatile global demand. The study aims to evaluate the importance of the competitiveness factors for cargo airports and identify areas for further improvement. The study applies the Best-Worst Method (BWM) to assess the cargo airports' competitiveness factors: 'Transport Capacity,' 'Airport Operations and Facility Capacity,' 'Economic Growth,' 'Financial Performance,' and 'Airport Brand Value.' The selected airports include Heathrow Airport, Aéroport de Paris-Charles de Gaulle, Hong Kong International Airport, and Incheon International Airport. The results identify 'Transport Capacity' as the most significant competitiveness factor, and Hong Kong International Airport the best performing cargo airport. This research forms a reference framework for evaluating cargo airports' competitive position, which may help identify airports' relative strengths and weaknesses. Moreover, this framework can also serve as a tool facilitating the strategic design of airports that may accommodate both air cargo and passenger demand flexibly under the demand uncertainty.

This research analyzes users' cognitive responses to Out-Of-Home advertising content based in virtual environments. Specifically, it distinguishes the depth of advertisements as 2D or 3D and categorizes animation effects of light as a representation of virtuality into 'none', 'blinking', and 'flowing'. For this purpose, virtual reality content was developed, and after experiencing the content while wearing HMD, users' cognitive responses were investigated. Involving 60 participants, the study found that the interaction effects between depth perception and animation effects were not statistically significant, nor was the primary effect of depth perception. However, the main effect of animation showed statistically significant differences in users' attention, vividness, perceived intrusiveness, avoidance tendency, and flow. This study presents design elements that can be utilized in the production of virtual environment-based Out-Of-Home advertising and experimentally demonstrates that animation effects can serve as an effective means of emphasis in virtual environment advertising. These findings provide important insights for the creation and strategic planning of advertisements in virtual environments.
