Recently the trade patterns of the entire economy are rapidly changing on development of IT. The field of port logistics is enforcing a competitiveness through preliminary offer of information and a batch process for improving the structure of logistics management which is apparently high cost and the low efficiency since 1990. But a previous EDI is insufficient in process ability. Bemuse it costs for the purchasing and maintenance of the expensive communication devices which is operated on the VAN environment. A web based EDI operating on an open network environment is needed to improve these problems and to handle transaction efficiently among many and unauthorized personals. Therefore, this study is willing to present a new web based model of the pull process which extracts the data when the receiver is needed to improve the push process which is transmitting data unilaterally.

This paper aims to analyze the causal relationship between exports and regional economic growth based on the provincial data over the period from 1952 to 2004. To reflect the regional and chronical characteristics, this paper divides China into three regions; Eastern, Central and Western regions, and also the whole period into two sub-periods; before and after 1979 when the Open-door policy(ODP) was initiated and applies Granger causality analysis. The Granger causality tests showed that exports Granger cause economic growth in the Eastern region, but not in the Central and Western regions, as a whole. When the period is divided, in the Eastern region, causal relation between the two variables was not found before the Open-door policy. For the second period, however it turns out that exports cause the region's economic growth. This result is consent with the fact that the region has been a main beneficiary of the policy. For the Central region, the tests showed no causality in the pre-ODP period, but significant bidirectional causality in the post-ODP period. Meanwhile, in the Western region, exports turned out causing economic growth significantly before the ODP, while economic growth appeared to causing trade after the ODP.

This study aimed to review the reorganization of fisheries and the future tasks in accordance with the establishment of new fishery order in the Northeast Asian Seas. As the United Nations Convention on the Law of the Sea, which recognized the sovereign rights of Coastal States in a 200-nautical mile exclusive economic zone (EEZ), entered into force in 1994, the three countries of Korea, China and Japan ratified the United Nations Convention on the Law of the Sea in 1996 and started negotiations to establish a new fishery order consistent with the EEZ system. However, a conflict of interest occurred because of differences in fisheries between countries, negotiations many times have proceeded, resulting in the signing of fishery agreement between China and Japan in 1997, Korea and Japan in 1998, and Korea and China in 2000. Each fishery arrangement consists of a dual system of EEZ and provisional waters (middle waters, provisional waters). The two countries are engaged in mutual fishing based on coastal states in EEZ, and in the fishing operation under the principle of flag state in provisional waters. There are overlapping or ambiguous jurisdictions in the intermediate waters and provisional waters that are jointly available to both fisheries. The presence of these seas is a challenge to the establishment of a reasonable international fisheries management system for the entire Northeast Asian Seas. In this context, the challenges of the reorganization of the new fisheries order are as follows: 1) conversion to a fishery order for coexistence of fisheries, 2) expansion to an international fishery management system, and 3) establishment of a multilateral fishery cooperation system. Although the jurisdiction of their own waters has been expanded through the establishment of EEZ according to new fishery order, the need for mutual cooperation grows when considering the movement and migration of fishery resources, fishery management, fish consumption and trade. In addition to the fisheries cooperation between the governments, it is also necessary to revitalize the civil cooperation focused on fishermen who exploit fishing grounds together.

The developing countries have a lot of dormant resources, attempting the take-off of economic growth. The theory of 'vent for surplus' and Lewis model provide a good cornerstones to analyze the effect of export, FDI and domestic production on employment. This paper attempts to do empirical test to figure out what factor is significant as the determinant of Chinese employment. For this test, the estimation equations are derived from the Cobb-Douglas production function. The results are that the domestic production affects the most positive employment, compared to FDI and export. Unlikely general expectation, export doesn't have an substantial effect on employment in China. It is also found that the absorption of technology through export is lower than that of FDI in terms of the effect of technology on employment. So it is suggested that the employment policy should be shifted toward the increase of domestic production by using FDI rather than by promoting export industry. to reduce the internal imbalance.

Purpose - The purpose of this study to explore factors consumers prioritize when purchasing seafood online. The originality of the study lies on adopting AHP-based approach in analyzing prioritized purchasing factors of seafood online. Design/methodology/approach - A survey was conducted targeting Korean consumers who have purchased seafood online. AHP method was applied to rank factors consumers prioritize before making decision. Findings - First, product's factor ranked first among other high level factors including delivery service, seller, online platform. Second, sanitation, taste, country of origin ranked first, second, third respectively, within product's factors. Third, safe delivery, timeliness, information accuracy ranked first, second, third respectively, within delivery factors. Fourth, consumer reviews, consumer response ability, promotion ranked first, second, third within seller factors. Fifth, Personal information management system, credibility, user-friendliness ranked first, second, third, within online platform factors. Research implications or Originality - To activate seafood online market, it is crucial to assure consumers that the seafood is well managed in a sanitary way from the production site to table. Existing government programs such as seafood traceability system, HACCP, and cold-chain infrastructure needs improvement. Due to highly perishable characteristic of seafood, delivery factors matter when purchasing online. Online platforms needs to continue to improve delivery service. Seafood products are mostly not branded and without objective information about their properties. Creating quality classification and seafood brands are likely to help consumers chose seafood online.

In this paper, we present the regression analysis and design optimization for improving the permeability of 3D woven materials based on numerical analysis data. First, the parametric analysis model is generated with variables that define the gap sizes between each directional wire of the woven material. Then, material properties such as bulk modulus, thermal conductivity coefficient, and permeability are calculated using numerical analysis, and these material data are used in the polynomial-based regression analysis. The Pareto optimal solution is obtained between bulk modulus and permeability by using multi-objective optimization and shows their trade-off relation. In addition, gradient-based design optimization is applied to maximize the fluid permeability for 3D woven materials, and the optimal designs are obtained according to the various minimum bulk modulus constraints. Finally, the optimal solutions from regression equations are verified to demonstrate the accuracy of the proposed method.

As global trade and maritime port environments change, the need to respond to larger and faster ships is increasing. Accordingly, new ports are being built around metropolitan cities such as Busan and Ulsan. In general, a compaction method using sand or gravel is applied to the construction of a new port. However, due to the lack of sand or gravel and the difficulty in securing economic feasibility due to the increase in unit price, the deep mixing method has recently been used. Therefore, in this study, CMD-SOIL using circulating resources was applied to the Ulsan area, and the applicability was determined by analyzing the laboratory mixing test and boring results at in-situ. As a result of the test, it was analyzed that it showed more than the design mixing strength, and it was possible to secure the similar performance as blast furnace slag cement. In addition, it was analyzed that the design standard strength can be sufficiently secured as a result of in-situ boring. Therefore, considering the field applicability in the Ulsan, it is judged that the use of CMD-SOIL is possible.

Russia's push in the Asia-Pacific region stems from its interests that have the national, regional and global dimensions. In their turn, the aims of this policy are civilizational, geopolitical, economic and prospective, with a long-term outlook. In the course of their achievement, cooperation with Northeast Asia's countries will play one of the key roles owing to the factors of geographic proximity, Northeast Asia's economic potential, risk hedging and a growing influence Northeast Asia exerts upon the global development. A new cooperation paradigm between Russia and the states of Northeast Asia should be based upon establishing and cementing self-reproducing ties. This is the central aim of Russian initiatives in relations, with Japan, the Republic of Korea, Democratic People's Republic of Korea, Mongolia and China. However, numerous obstacles ranging from Russia's absence in the regional free trade agreements and supply-production chains of value-added production to the permanent international instability generated by Pyongyang's missile-nuclear developments hamper the practical implementation of this task. Realizing the necessity to give an additional impetus to this new cooperative paradigm, Russia has to develop directions with an apparent consolidating effect. The most promising may be the establishment of a permanent security forum based upon Northeast Asia Peace and Security Mechanism chaired by the Russian Federation. The urgency of this measure and its expected support stem from the necessity to strengthen security in Northeast Asia, a task neither the US-led hub-and-spoke system nor ASE-AN-led multilateral dialogue venues have been able to resolve. The issues addressed at the security forum must include the unification of approaches to North Korean nuclear issue and producing a document specifying actions of the claimants on the disputed maritime territories in the "direct contact" situations. At the expert level, Russia has elaborated on the idea to establish such a forum outlining the spectrum of the key directions of cooperation. With the urgency in the establishment of this dialogue venue, its agenda has to be coordinated with the agendas of the existing security systems presented by the US alliances and the ASE-AN-led multilateral negotiations. The practical implementation of this initiative will strengthen security in Northeast Asia as its challenges will be resolved in the pre-emptive way based on coordinated approaches. Therefore, Russia as the Eurasian state will be one of the role players in the advent of the Asian century.

This paper aims to investigate the causal relationship between geopolitical risk and stock price volatility in the shipping industry. Given its international nature and dependence on global trade, this industry is exposed to various uncertainties and risk factors. This study specifically focuses on the impact of geopolitical risk, which has gained significant attention in recent years due to events such as the Russia-Ukraine War and the Israel-Hamas War. To analyze this relationship, the study utilizes vector autoregressive model-based causality tests. The research estimates the causal relationship between geopolitical risk indicators and the stock price volatility of five shipping companies listed on the Korea Exchange. The study covers the period from 2000 to 2023. The results indicate the following: Firstly, an increase in geopolitical risk leads to a rise in stock price volatility for shipping companies. Moreover, the impact of actual geopolitical events, rather than just diplomatic disputes, is statistically significant. Lastly, the impact of geopolitical risk is particularly significant in the bulk shipping sector.

Purpose - The purpose of the study was to find out how the Korean government reflected its policy goal and direction by analysing the budget allocation on support measures for the Korea-China FTA in the fisheries sector. Design/methodology/approach - Concentration Ratio, Herfindahl-Hirschman Index and BCG Matrix were applied to the government's budget allocation on support measures for the Korea-China FTA in the fisheries sector. Findings - The study result shows that the government has provided various programmes without over-investing in some programmes. Meanwhile, the government has increased its budget for some programmes that are in line with its long-term policy goals, such as promoting sustainable fisheries and transforming fisheries into a value-added industry. In addition, the government has reduced its budget for programmes that threaten its fiscal sustainability. Research implications or Originality - The Korean government planned a 10-year budget plan for support measures for the fisheries sector after the implementation of the Korea-China FTA. Since 2016, the government has operated the subordinate programmes under the 10-year budget plan each year, reflecting its new policy direction, which takes into account both domestic and external factors. Accordingly, this study is meaningful in that it allows us to examine the government's policy direction for the fisheries sector after the Korea-China FTA.
