In case of EU and USA, a short sea shipping and coastal shipping which are safer and environmentally better than road transportation are used widely. But a share of freight transport by a coastal transportation is extremely poor in South Korea. In this paper, we propose a Mokpo-Jeju intermodal transportation based on logistics analysis results. Firstly, we investigate a freight and passenger of a Mokpo-Jeju shipping route. And secondly, the intermodal transportations such as sea-train, sea-road, RORO ship system are investigated. Finally, we propose a coastal transportation system utilizing RORO ship system for Mokpo-Jeju shipping route and identify a technical feasibility of a coastal transportation system.

The LMS(Least Mean Square) algorithm is generally used because of tenacity, high mating spots and simplicity of realization. But the LMS algorithm has trade-off between nonuniform collect and EMSE(Excess Mean Square Error). To overcome this weakness, variable step size is used widely but it needs a lot of calculation load. In this paper we consider new algorithm, which can reduce calculations and adapt in case of environment changes, uses original signal and noise signal of IGC(Instantaneous Gain Control). For the real time processing of IGC algorithm, we remove the logarithmic function. The performance of proposed algorithm is tested to adaptive noise canceller in automobile. We show implemented LabVIEW FPGA system of IGC algorithm is more efficient than others.

Manufacturing processes in industrial complexes produce NOx, SOx, VOCs, which cause particulate matter (PM). Therefore, this study analyzed the characteristics of each industrial complex by using scattered public data, matched the existing particulate matter(PM) reduction technology, and proposed an optimized reduction plan. The application of matching technologies and facilities by industrial complexes based on data is able to mitigate NOx, SOx, and VOCs which cause particulate matter in the process in advance. This way can be an effective alternative in order to reduce PM in the manufacturing processes as well as industrial complexes.

This study analyzes how the port connectivity network has changed with the restructuring of the liner shipping alliance and explores the impact of these changes on network characteristics using social network analysis (SNA). While due to economies of scale, the scale of ports and liner shipping has expanded, the goal of shipping companies has changed to achieve cost-effectiveness due to the diseconomies of scale. Such changes in the environment have greatly affected ports according to the strategies of major liner alliances, and port centrality has shifted in response to restructuring in strategic alliances. This research confirmed that port centrality has continuously changed, and the reason for this phenomenon was analyzed through the derived main network centrality indices. This finding provides significant implications for port authorities and terminal operators to consider different perspectives when planning for sustainable growth and management.

The objective of this study is to verify the effect of the market orientation, CEO capacity, and environmental characteristics of overseas markets on the performance of overseas expansion among the success factors of domestic overseas expansion companies. For this purpose, employees of domestic overseas companies based in the Seoul metropolitan area were surveyed, and the hypothesis test was conducted. As a result of the verification, among the contributors to overseas advancement of domestic overseas companies, the factors of CEO capacity, overseas business_education ability, market environment and market size have a significant positive effect on the financial performance of overseas expansion. However, market-oriented factors were found to have no significant effect on the financial performance of overseas expansion. Among the contributors to overseas advancement of domestic overseas companies, the market-oriented factor, the customer-oriented factor, has a significant positive effect on the non-financial performance of overseas expansion. However, factors in CEO competency and environmental characteristics in overseas markets do not have a significant positive effect on the non-financial performance of overseas expansion.

Purpose - The distribution of agricultural products is changing due to recent shifts in environmental free trade. Specifically, the competitiveness of domestic agricultural products has weakened as a result of the Korea-China Financial Trade Agreement. Agricultural producers are faced with increasing difficulties and organized production centers are growing in importance daily. To overcome this crisis, agricultural producer organizations are vying for environment-friendly agricultural certifications, Good Agriculture Practices (GAP) and Hazard Analysis and Critical Control Point (HACCP). In particular, as consumer demand for higher safety grows, farmers are increasing their certification rates. Therefore, this certification system is expected to help strengthen the competitiveness of agricultural producer organizations. Research design/data/methodology - Organized production centers are classified by certification. A survey was conducted with 91 organizations using factor analysis and logistic regression analysis for the examination. The factor analysis results are as follows. Raw material procurement, education·specialization, marketing, joint business, organizing ability, business management, effectiveness, certification, and larger organizations were classified as the nine types of factors. These factors affect the organized production centers and are used in the logistic regression analysis. The purpose of such research and analysis is to suggest a direction for future production center policies. Results - The basic statistical results are as follows: analysis of the producer organizations of 91 sites, average number of members per site of 1,624, and average sales of 25,961 million won. Additionally, the average income per farmer is 175 million won, and the pooling system rate is 53.5%. The factor analysis results are as follows. Factor 1 consists of contract cultivation, ongoing shipment, selection subdivision, traceability, and major retailer management. Factor 2 consists of manual cultivation, specialty selection, education program, and R&D. Factor 3 consists of advertising, various dealers, various sales strategies, and a unified sales counter. Factor 4 consists of agricultural materials co-purchase, policy support, co-shipment, and incentives. Factor 5 consists of the co-selection and pooling system. Factor 6 consists of co-branding and operating by the organization's article. Factor 7 consists of the buy-sell ratio and rate of operation of the agriculture promotion center. Factor 8 consists of bargaining power in volume and participation rate of farmer certification. Factor 9 consists of increasing new subscribers. The logistic regression analysis results are as follows. Considering the results by type of certification, the environment-friendly agricultural certification type and the GAP certification type have a (+) influence. GAP and HACCP certification types affecting the education·specialization factor have a (+) influence. Considering the results for each type of certification, the environment-friendly agricultural certification types on the effectiveness factor have (-) influence; the HACCP certification types on the organizing ability and effectiveness factor have a (-) influence. Conclusions - Agricultural producer organizations should develop plans as follows: The organizations need to secure education for agricultural production; increase the pooling system ratio for sustainable organizational development; and, finally, expand the number of agricultural producer organizations.

Today's Internet environment is growing rapidly, and transactions based on it are also rapidly increasing. E-commerce allows merchants and consumers in different countries to easily trade goods across borders. However, the increase in international consumer transactions through the Internet is accompanied by an increase in disputes. International consumer transactions are characterized by a distinction among long distance, small sum, and different jurisdictions. International consumer transactions cannot be solved only by way of resolving disputes in past international transactions. The best way to resolve disputes between international carriers and consumers is through the Internet. In this regard, UNCITRAL has been preparing to enact legislation on ODR as a solution to international electronic trade disputes and, as a result, UNCITRAL adopted guidelines for operating the ODR procedure for building the ODR platform. The European Union has also increased its disputes in the European Union, which is active in the intra-regional market. Institutional improvements were made to solve this problem; therefore, the European Union (EU) has enacted the ODR Regulations for EU consumer disputes. Based on such, this study constructed the ODR platform, which is used as a way to resolve consumer disputes in the regional market.

Purpose: Market basket analysis is one of the most frequently used methods in the retail industry today as a technique to discover the product association. It is empirically analyzed how these product associations differ regionally in the case of the United States. Research design, data, and methodology: Based on the purchasing data of consumer panels collected from 49 US states, the association rules for each state was extracted with the corresponding lift values indicating product association. The difference in lift values in 49 states by the association rule was compared and tested for 49 states and for 4 census regions (Northeast, Midwest, South, West). Results: The association rules of 3/4 of the same association rules show positive associations or negative associations depending on the lift values of the states. There were significant differences in the lift values for 49 states, and for 4 census regions. These significant differences in the lift values were found to be related to the distance between states and whether states belong to the same census region. Conclusions: Retail product associations shown by market basket analysis may vary depending on regional distance or regional heterogeneity. It is necessary to pay attention to these points in multi-store environment.
