This study reviews maritime transport policy regarding liner conference and the changes in the liner market over the decades. Liner shipping industry has long been protected from competition by block exemption. To prevent excessive competition in punctual operation and its inelastic market structure, liner shipping companies formed conferences that are protected to fix the prices under the law. In the US, deregulation in transport sector began from 80's and continuing with OSRA 1998, conferences were dissolving. On the other hand, the EU with close conference system, Regulation 4056/86 contained block exemption remained in force for unlimited time without review clause. However, in Oct 2008, the EU has announced its removal, and conferences were no longer permitted to fix the price nor exchange information. Although OSRA 1998 has already broken up conferences by allowing individual service contracts, but the repeal of the immunity for price fixing will alter significantly the rule on cooperation in the industry since it is a unilateral move by the EU, especially in transatlantic lane. There are rapid changes in shipping market getting much more complicated, and with removal of 4056/86 allowing the market to be more competitive, opening up the industry with far more diverse strategic options. Hence this paper reviews on liner shipping industry and its changes of policies over the years from protected market to open competition market of today.

Fishery industry is an important part of agricultural industry in coastal countries. The purpose of this study is to use the theory of industrial competitiveness for reference, use Analytic Hierarchy Process (AHP) and Delphi method to establish the evaluation index system, and analyze the fishery industry competitiveness of 11 coastal provinces in China. This study data came from China Fishery Statistical Yearbook 2020. The results show that Shandong Province is the most competitive province in fishery industry among the coastal provinces. The inter-provincial differences are great. Not only the resource endowment is the factor that affects the fishery industry competitiveness, but also the long-term profitability is too. The proportion of recreational fishery in the fishery economic output value has become one of the main indicators to measure the competitiveness of the fishery industry. The findings of this study suggest that all regions should adopt measures in accordance with local conditions, promote the integrated development of the fishery industry, enhance the added value of fishery products and enhance the competitiveness of fishery industry. The disadvantage of this study is that the fishery industry competitiveness of China's coastal provinces is only compared and analyzed. The future direction is to carry out a comparative study on the international competitiveness of fishery with other east Asian countries.

The Korean Government decided to reduce 30% of carbon emissions as of 2020, tightening regulations to reduce greenhouse gas in the international society. Therefore it will burden Korean logistics industry that overland trucking freight covers 70~80% of all, to lower emissions. As known, rail and coast(feeder) transport systems can be substituted for road transport but there are many problems to solve in Korean multimodal (intermodal) transport system such as time, cost, etc. Because of this, multimodal transport system should be improved systematically. For the reason, it aims to study a conceptual model with Thinking Process of TOC(theory of constraints) and System Dynamics to help improve the existing multimodal transport system for green logistics.

Background: With the recent rapid industrialization, occupational safety and health (OSH) has become an important issue in all industrial and human activities. However, incidents of injuries and fatality rates in the Ghanaian industry sector continue to increase. Despite this increase, there is no evidence regarding the element of OSH management in transport activities in Ghanaian industries. Thus, this study aims to examine the perceptions regarding the importance of safety and health in work-related transport activities in Ghanaian industries. Methods: A survey data collection technique was used to gather information on best safety practices over a 5-month period. We randomly selected 298 respondents from industries to answer structured questionnaires. The respondents included drivers, transport managers, and safety engineers. Standard multiple regression model and Pearson product-movement correlation were used to performed the analysis. Results: The result shows that for interventions to improve safety and health, concentration has been on drivers' safety practice with less attention to safe driving environments and vehicle usage. Additionally, the respondents are aware of the importance of OSH in transport activities, but the level of integration does not measure up to the standard to reduce operational accidents and injuries. Finally, strong commitment to changing unsafe practices at all levels of operations appears to be the effective way to improve safety situations. Conclusion: OSH culture is not fully complied in industries transport activities. This study, therefore, supports the use of safety seminars and training sessions for industry workers responsible for transport operations for better integration of safety standards.

Government tries to revise the article 25 in Korea Maritime Transport Act which describes subject of coastal carriage for exported-imported container cargoes. The subject of coastal carriage will be replaced coastal carrier by ocean liner carrier according to the revised article 25. By adopting the revised article, coastal shipping industry will be deteriorated in terms of returns on investment, sales and etc. Even though the revision is inevitable to harmonize the flow of exported-imported container cargo movement, coastal shipping industry should be developed and restructured to get competitive power and to set up an efficient international logistics system. To enhance competitive power of coastal shipping companies successfully, government must realize the importance of coastal shipping, and aid the industry through various methods such as arrangement of law and regulation, indirected financial assistance, decrease of tax rate, etc.

해상운송은 개별 국가만이 아니라 세계 경제에 높은 영향력을 미치며, 글로벌가치사슬(GVSc)을 통한 분업 실현에 이바지 하고 있으며 이러한 국제분업 활동은 일상화되어 있다. 해상운송업 사이에도 국제분업을 통한 글로벌 가치사슬(GVSs)이 존재하며 국가 간 해상운송업 사이 혹은 관련 산업 사이에도 거래관계가 발생해 상호 연관구조가 긴밀한 국가들이 있다. 이에 본 연구에서는 아시아개발은행(ADB)에서 1년 단위로 발표하는 국제산업연관표(WIOT)을 이용하여 63개 국가 중에서 세계 30대 선박 보유국 안에 포함되면서 수상운송업의 총 산출액이 높은 14개 국가를 대상으로 수상운송업 간의 상호 연관구조를 분석하였다. 분석을 통해서 우리나라 수상운송업과 높은 연관구조를 가진 국가와 우리나라 수상운송업의 특징을 확인하였다. 분석 결과 우리나라는 투입구조에서 국산 중간재비중이 약 70%로 유럽의 주요 해운 국가 대비 국내산 이용 비율이 높았다. 하지만 2000년 이후로 꾸준히 국외 중간투입이 증가하면서 국외 산업과 연관구조가 높아졌으며, 발생하는 부가가치는 하락하였다. 줄어드는 부가가치에 비해 국내 산업으로 생산유발계수는 크게 변화가 없어 같은 금액 투자에도 국내에 미치는 경제적 영향은 줄어든 것으로 평가되어 해운산업의 부가가치를 높이기 위한 정책적인 방안이 필요한 것으로 생각된다. 우리나라 수상운송업과 높은 연관구조를 가진 국가는 투입구조 상에서는 미국(USA), 배분구조에서는 싱가포르(SIN), 일본(JPN) 순으로 해당 국가의 생산활동에 높은 영향을 받는 것을 확인하였다. 생산유발계수를 통한 연관구조를 보면 우리나라 수상운송업과 높은 연관구조를 가진 국가의 수상운송업은 싱가포르(SIN)이다. 싱가포르(SIN)는 유럽 항로의 중간지역으로 우리나라 수상운송업과 상호 간에 높은 생산유발효과를 주고받는 것을 확인할 수 있었다.

The wind tunnel test of large-scale sectional model and computational fluid dynamics (CFD) are employed for the purpose of studying the aerodynamic appendices and mechanism on suppression for the vortex-induced vibration (VIV). This paper takes the HongKong-Zhuhai-Macao Bridge as an example to conduct the wind tunnel test of large-scale sectional model. The results of wind tunnel test show that it is the crash barrier that induces the vertical VIV. CFD numerical simulation results show that the distance between the curb and crash barrier is not long enough to accelerate the flow velocity between them, resulting in an approximate stagnation region forming behind those two, where the continuous vortex-shedding occurs, giving rise to the vertical VIV in the end. According to the above, 3 types of wind fairing (trapezoidal, airfoil and smaller airfoil) are proposed to accelerate the flow velocity between the crash barrier and curb in order to avoid the continuous vortex-shedding. Both of the CFD numerical simulation and the velocity field measurement show that the flow velocity of all the measuring points in case of the section with airfoil wind fairing, can be increased greatly compared to the results of original section, and the energy is reduced considerably at the natural frequency, indicating that the wind fairing do accelerate the flow velocity behind the crash barrier. Wind tunnel tests in case of the sections with three different countermeasures mentioned above are conducted and the results compared with the original section show that all the three different countermeasures can be used to control VIV to varying degrees.
