The purpose of this study is to look into the consumers who show the consumption patterns of brand switching and repeated purchasing, find the decision factors of their brand switching and repeated purchasing, analyze the difference in marketing response variables being represented as corporate promotion activities in the brand switching and repeated purchasing process, and provide a suggestion to apply the result to marketing Therefore, it tries to help the firms, which develop push marketing as the result of excessive competition between distributors and sales competition focusing on external appearance, recognize consumers as individual substances; to propose proper efficient promotion activities; to let consumers increase loyalty to their trademark and continue to purchase their products repeatedly; and to induce competitor brand consumers to do brand switching. The results of this study are presented as follows: First, consumers who prefer events, price discount, samples, and product premium which means the products with brand or logo on them had the feature of repeated purchasing. Secondly, service benefit, point-type promotion, cost-saving satisfaction didn't affect brand switching, and only the consumers who prefer coupon-type promotion did brand switching. Thirdly, a distribution type produced the moderating effect between the repeated purchasing and coupon and coupon-type promotion, and between brand switching and service benefit.

The pace of sustainability transition within the maritime industry has been accelerating. This shift primarily necessitates changes in the industry's heavy reliance on fossil fuel-driven ecosystems. Additionally, numerous sustainability laws and regulations, such as the EU's CBAM and IMO's EEXI, have been implemented. This transition is poised to amplify the competitive edge of firms equipped with greater resources, as it introduces substantial operational burdens due to expensive eco-friendly fuel adoption and regulatory compliance. To diverge from the traditional competitive landscape, this paper aims to explore innovative maritime finance models enabling domestic firms to gain competitive advantages on a global scale. Employing analogical reasoning and modeling as a research method, this paper demonstrates that maritime firms can leverage the sustainability transition by aligning sustainable maritime operations with ETS (Emission Trading Schemes). Expanding on this novel approach, the paper delves into potential connections between CCM (Compliance Carbon Market), VCM (Voluntary Carbon Market), and digital asset exchanges. This newly proposed digital/net-zero maritime ecosystem holds the potential to significantly impact the shipping, shipbuilding, and ship finance industries, positioning Busan as a sustainable maritime finance hub. This study holds significance as pioneering research that may stimulate subsequent case-based studies and offer strategic guidance to market participants and policymakers as the maritime industry moves towards a net-zero transition

While the importance of adopting cloud computing service has been emerged, comparatively little research has been conducted on examining factors of an individual user's intention to switch toward cloud computing service. Hereafter, this study presents and empirically tests users' intention to switch to cloud computing. Our model posits that the characteristics of cloud computing such as effectiveness, economics, accessability, switching cost, security concern, and satisfaction toward existing IT service to cloud service affect perceived value, which in turn, influences intention to switch. An experimental study using student subjects provided empirical validation for our proposed model. Survey data from 204 respondents was used to test the model using partial least square analysis. As the result of the analysis, five hypotheses out of seven hypotheses were supported. According to our results, among the characteristics of cloud computing, effectiveness, economics, switching cost, and security concern were found to have significant impact on users' intention to switch that mediated by perceived value. Based on our research findings, we hope that this research will stimulate researchers' interest in the emerging area of cloud computing adoption.

The purpose of this research is to investigate the factors that impact customer satisfaction and loyalty in mobile payment services. Specifically, this research (1) studies the influence of company reputation on customer satisfaction and loyalty, (2) examines service quality dimensions that increase customer satisfaction, and (3) assesses switching barriers as moderators in influencing customer loyalty. Findings of this empirical research reconfirm the point of view that company reputation, service quality, and switching barriers are crucial for customer satisfaction in mobile payment services. The research methodologies that were used to verify the hypothesis in this study included customized surveys and structural equation modeling. The results demonstrated that company reputation significantly affects customer satisfaction and loyalty. Additionally, the results indicated that only two of the five total service qualities, ease of use and the security/privacy qualities, have positive influences on customer satisfaction. Customer satisfaction has also proven to be a significant influence on loyalty. Lastly, the results showed that among the factors of switching barriers, the factors of lost performance costs, sunk costs, setup costs, the attractiveness of alternatives, and service recovery have moderating effects on the relationships between customer satisfaction and loyalty. Base on the results, this research recommends that firms aim at devising integrated strategies that make switching barriers act as complements to customer satisfaction.

It needs to consider of turns during a path-finding on real road network. Because a car is delayed by waiting a traffic signal and decreasing speed when drived in a turn road such as cross road and slip road. If a straightness of a path is increased, a real cost of traveling should be able to decrease. An older method, the algorithm with Turn Heuristic, considered of this case. The algorithm, that differently gave weights to left, right and U-turns, improved a straightness of a path, but increased a cost of exploring. In this paper, we propose a improved Turn Heuristic Algorithm. Proposed algorithm uses Dynamic Turn Heuristic. It is able to more decrease a cost of exploring than older method by using the Turn Heuristic in a part of path-finding.

According with annual report by the OECD (Organization for Economic Co-operation and Development), South Korea is at the top of the list of countries with bad air pollution (fine dust particles) and the South Korean government announced the cause to be due to the particle emissions of large and old diesel vehicles. To solve this issue, the government (jointly with related ministries), promoted the "Special Measures for Comprehensive Fine Dust Management Program" as a way to improve environmental pollution by reducing the overall output of fine dust particles emitted by public vehicles. The measure implemented a gas subsidy system to convert eco-friendly vehicles of city and chartered buses throughout the country. In this study, we take a look at the economical evaluation, comparison and analysis of the conversion of diesel vehicles to natural gas (CNG) vehicles. This report represent the basis for the need to expand the funds of the subsidy program and reviews the feasibility of the policy by taking into consideration the social and economical benefits and the effect in the environment when converting diesel fuel to natural gas vehicles through the type-specific fuel conversion scenarios.

This paper deals with modal shift projects and policy of modal shift services at home and abroad. This study aims to review the results of foreign modal projects in advanced countries and to suggest policy directions for promoting modal shift services in Korea. This paper consists of three main sections: concept of modal shift policy; analysis of modal shift projects and policy at home and abroad; policy directions of modal shift services in Korea. In recent years, shippers who shift mode from truck to rail or coastal shipping are subsidized by the government. The government intends to encourage modal shift services of shippers, as shown in the example of Marco Polo in EU. It is identified that the government should devise effective policy for the successful implementation of truck-rail modal shift in Korea. It is suggested that the policy goal of modal shift must be clear and its attainment is feasible in order to promote modal shift services here. It also turns out that indirect supply policy works better than direct one. Freight transport environments differ between countries. It, thus, hard to directly apply foreign policies to Korea's freight transport field. Korea is at an inceptive stage of exploring foreign modal shift policies and promoting modal shift services in Korea. We will gain from the wide range of case studies, which analyze the modal shift successes and failures experienced by advanced countries. It is necessary to use them with care.
