The paper presents available options that Korea can adopt in an effort to promote eco-industrial development in a near future. What is missing and the reasons why Korea is behind the other countries in the area are: 1) Lack of holistic view and the integrated approach toward economy and environment in policy implementation, 2) Lack of understanding, among entrepreneurs, of the concept of productivity per input resource, and the fact that not only labor and capital productivity but also the total productivity enhancement is vital for industry's competitive edge; There has been no driving force in the market to develop economies of system integration to turn industrial wastes to valuable input resources, 3) Unsupportive regulatory system regarding the trade of by products, and 4) Lack of financing and incentive mechanism. 5) Lack of information forum. Regulatory reform should be taken for the direction that in effect increase the price of disposal and motivate firms to seek symbiotic relationship with other firms, and facilitate trade by-product between firms. Financing and incentive mechanism should be introduced in order for the industry to find easy access to the opportunities for organizing the network to transform wastes in negative value to the value added resources. Also information network should be established to provide a market for by-product exchange and public education to improve industry's environmental performance.

This case study explores the stock sale, the resulting governance structures, and the airport management and development in Beijing Capital International Airport and Shanghai International Airport at Pudong. It is imperative for Incheon International Airport Corporation (IIAC) to change the management paradigm to survive in the changing environment and to become hubs in the relevant regions. And IIAC needs to search for the new ownership and governance structure to cope with the internal and external demands for innovation. In this study, along with the recent trends of the global airport industry, we suggest the implications for the IIAC's major decisions, especially, for the stock sale, the resulting governance structure, and the airport development and management. It is suggested that Korean government retain the majority control in the process of privatization to keep IIAC as a government-owned enterprise to provide the public goods to the citizen. Furthermore, to maximize the value of stock sale, IIAC needs to decide strategically the time and speed in the hybrid form of stock selling using trade sale and IPOs.

Globalization and regionalization are major trends in the international economic system. The severe competition among countries has signalled the need for a new international trade system as prescribed by the WTO, which regulates international trade practices. Additionally, expanding the activities and role of the Pan-Yellow Sea area in the world has a very important function in terms of regional cooperation and logistics environment. In this paper, the trading conditions and shipping transport problems of the Pan-Yellow Sea area (North-East Asia) were investigated. Shipping transport conditions in the Pan-Yellow Sea area, particularly Korea-China routes, were surveyed as well. A new Incheon-China container liner route was suggested as a partial remedy to some of the shipping transport problems of the Pan-Yellow Sea Area (North-East Asia). The Incheon-China Container Liner route is more efficient than Pusan and Pyungtaek Ports or the car ferry route to China in terms of transport time and expense. The transport burden indicator which includes the time and expense of transport, can be a useful tool in comparing these routes. Accordign to the transport burden indicator, the Incheon-China Container Liner route is more efficient than the Pusan, Pyungtaek, or car ferry routes. To establish a successful liner route between the ports of Inchon and China, there is a need to prepare three measures that contain short-term medium-term and long-term strategies. Furthermore, these measures should be prepared and adopted in phases, in accordance with considerations of future conditions for shipping and logistics in the Pan-Yellow Sea area.

Modern challenges in the educational environment force scientists and practitioners to search for an adequate answer. In particular, the war in Ukraine demonstrated the importance of developing information competence as one of the main means of distinguishing true information from a whole stream of fake news. This is especially relevant in connection with the introduction of distance learning when students must find and process a large amount of information on their own. Therefore, the purpose of the article is to analyze the training of higher education students through the prism of acquiring the necessary level of informational competence in war conditions. For this, general scientific and special research methods, as well as the experimental method, were used. In the results, the peculiarities of the interpretation of information competence in the distance form of education among modern researchers are determined, the psychological components of resistance to fakes are analyzed. Based on the conducted empirical measurements, it was established that thorough work on student education gives positive skills when working independently with Internet materials, strengthens the ability to distinguish false information and propaganda from the real state of affairs. The conclusions summarize the results of the empirical research and suggest ways to improve the situation with the formation of information competence.

Purpose - As the global product network expands through both internationalization and diversification of the multimodal transportation system, corporate strategies have shifted to emphasize the importance of a high value-added international logistics system. To guide policies and strategies to attract relevant industries, this study aims to analyze the location competitiveness of regional logistics distribution center to serve Northeast Asia. Design/methodology - Multi-criteria techniques are considered to offer a promising framework for evaluating decision-making factors. This paper employed an analytic hierarchy process to analyze the hierarchal structure of determinants for selecting the location of a regional logistics distribution center. Adopting both qualitative and quantitative evaluations, this study suggest political implications for a regional logistics distribution center development, such as the direction of political support, service differentiation and infrastructure development. Findings - This study developed a location competitiveness evaluation model, based on the case study of the major port-cities in Northeast Asia. Evaluation model incorporates five factors underpinning 17 components extracted using factor analysis. The results revealed that the logistics factor is the most significant factor for evaluating the competitiveness of a regional logistics distribution center. The remaining factors were market, costs, and services environment. Comparing qualitative and quantitative evaluations, results provide useful insights for a regional logistics distribution center development in Northeast Asia. Originality/value - This study revealed differences between qualitative and quantitative evaluations. The finding implies that prior works on evaluation models of competitiveness has not successfully measured the gap between quantitative data and expert' evaluations. To overcome this limitation, this paper considered both actual data such as actual distance, cost, the number of companies located, and expert opinions.

Elderly population has increased rapidly and adjusting the environment is in demand to support their health. To improve the living environment of elderly, an appropriate plan for customized home modification is needed upon the personal contexts. The purpose of this study is to explain the sequence and to build an insight on customized home modification for vulnerable single elderly. It is a case study based on single target that includes 6 months of execution period deeply seeking the appropriate plan for implementation. The target is a male elderly aged 74 living in a single story detached house. The various research methods are applied in this study including exploratory, participatory, action and trade-off preference researches. The result shows that plan for home modification is complex outcome of interlocking uniqueness between residence environment and resident situation. If customized modification is targeted for residentially vulnerable social group, more sensitive approach aiming for the highest result is required due to financial constraint. To conclude, comprehensive understanding of overall circumstances of a dwelling, a resident and various stakeholder is essential throughout the process. Since the aging-in-place of elderly cannot be achieved without self-sustaining living environment, customized home modification should be a tool to meet housing suitability. It is important to strengthen the experts and future workforce with networks of local residents to share opinions and appropriate plans.

Mobile agent is a software program that provides autonomy and mobility for the users in the networked computers by deciding its own movement place. Since mobile agent does not keep up the network connection and migrate its executable code under its own control, it can be often used in the unstable network conditions such as the wireless network and the heavy traffic network. In this paper, we show that the electronic commerce system can be developed efficiently to retrieve and trade the goods in the mobile computing environment by using the mobile agent paradigm. Multiple mobile agents migrate into the market directly, then negotiate and trade autonomously relevant goods and services. The execution result and executable code of the mobile agent are returned to the home place and reported to the users. We show that the mobile agent paradigm is suitable to build the mobile electronic commerce system by designing and prototyping the mobile market system.
