Purpose - The purpose of this paper is to look into some alternative for Korean shipping to overcome difficult situations in shipping, since then it is economic crisis at the end of 2000s. Research design, data, and methodology - The research method to be adopted is first to review theoretical overview about shipping cycle, and then examine difficult shipping situations and studies management aspect, which is to related to establishment of Korea Shipping Council. Results - The boom and bust situations in shipping market have been identified as result of economic crisis at the end of 2000s. Trade volumes have fallen and shipping tonnage has risen respectively. In practical terms, shipping industry has suffered from difficult situations, following to supply and demand of shipping market, and Korean shipping had to face hard time as well, according to lack of management ability of shipping company. Alternatively, it should be asked shipping forum like Korea Shipping Council. Conclusions - From situations of shipping markets since the end of 2000s, it is strongly asked that every parties got involved in shipping business should understand and share more expertise and knowledge of shipping market, which is finally related to decision- making process in shipping.

In this paper we study the delivery policy of internet bookstores and recommend the improved policy to increase customer satisfaction and sales revenue. We classify customers into two, the price-sensitive and the delivery time-sensitive, and develop a new shipping method, the unhurried shipping, for the price-sensitive who are reluctant to pay shipping fee for the small purchase but willing to wait extra time for the ordered goods. The customers could get discount on shipping fee by the unhurried shipping but have to accept the longer delivery lead-time. We investigate the possible ways to reduce costs with the prolonged delivery time and show that some costs regarding shipmentand inventory could be saved in order to make up for additional shipping costs for the price-sensitive.

This paper describes dynamic finite element analyses performed to study the dynamic behaviors of a shipping container under the impact onto rigid target due to the accidental fall from the hight of 9 m. Using two and three dimensional techniques, the shipping container which gave the maximum damage, ten different drop orientations are considered ; at intervals of $5^{\circ}$ from $45^{\circ}$ to $90^{\circ}$ According to the present results, the orientation of the shipping container which gave the maximum damage is $85^{\circ}$ from horizontal for oblique drop in the primary impact. In the optimal design of the shipping container, the impact limiter material must be considered importantly because it's proper selection affects the weight and the manufacturing cost of the shipping container. The analysis of the shipping container in this paper demonstrated that the shipping container is structurally sound relative to the regulatory drop test requirements.

Extracting the character region(container identifier) in the image of a shipping container is one of the key factors in a system for identifying a shipping container automatically To improve the performance of the automatic recognition system for identifying a shipping container, thus a method partitioning the character region more correctly and efficiently is needed. In this paper, an efficient method is proposed to extract only the character region in the image of a shipping container. The proposed method removes noises that are not possibly related to the character using morphological operation, then the image is binarized using the threshold value that is determined from the image obtained previous step. Finally individual character area is extracted from the binary image. Also experiments are conducted to verify the efficiency of the proposed method. The results show that the proposed method partitions the character region correctly from container images.

Purpose - The purpose of this paper is to seek some alternative to overcome difficult shipping situations for overcapacity pursuing economy of scale, which is widely spread in world shipping. Research design, data, and methodology - The research method to be adopted is first to review evolution of larger ships in terms of theoretical overview, and shipping market is examined, and it is studied some problems and solutions in relation to larger ship as field research aspects. Results - Supply and demand of shipping market is flexible and unpredictable nature of market. Sometime fierce competition has spread out the market, and shipowner may deploy mega ship in terms of economy of scale, etc., to overcome the difficult market situations. Both carrier and shipper have their own positions in this matter concerned. However, it causes some problems in the market including port matters, etc. Therefore, it is asked to solve this problems of larger ship employed in the markets, throughout shipping alliances, etc. Conclusions - Over tonnage done by larger ship has caused some problems in the shipping markets, forming monopolistic market by small number of larger shipping companies, destroying oligopolistic nature of shipping business, therefore, the answer is strategic alliance to collaborate each other.

Given the cyclicality, seasonality, and capital-intensiveness, the development of the shipping industry has long been contingent on corporate financing activities. As such, there have been a growing number of cities in East Asia pursuing a global maritime financial center in order to support their domestic shipping industry. However, it is widely accepted that financial services relevant to shipping in East Asia are quite under-developed compared to those of other leading maritime financial centers in Europe and North America. In this regard, this paper aimed to construct an evaluation index of maritime financial centers in terms of financial ecological environment for the purpose of highlighting the current status of development and suggesting future directions. Furthermore, this paper examined the development of shipping finance in Qingdao as a numerical example using the fuzzy comprehensive evaluation and compared results with those of Shanghai.

The wave impact on ships could cause local damage to the ship's hull, which has been a concerning issue during the ship design process. In recent years, local structural damages of ships caused by slamming loads have been reported by accident; therefore, it is necessary to study the local slamming pressure loads and structural response assessment. In the present study, slamming loads around the ship's bow region in the presence of regular wave have been simulated by RANS equations discretized with a cell-centered finite volume method (FVM) in conjunction with the $k-{\Box}$ turbulence model. The dynamic structural response has been calculated using an explicit FE method. By adding the slamming pressure load of each time step to the finite element model, establishing the reasonable boundary conditions, and considering the material strain-rate effects, the dynamic response prediction of the bow flare structure has been achieved. The results and insights of this study will be helpful to design a container ship that is resistant enough to withstand bow flare slamming loads.

Purpose - The purpose of the paper is to examine disconnection between supply and demand shipping market, which means shipowner has determined to raise capacity in bust period. Research design, data, and methodology - The research method to be applied is first to look into conceptual theory about shipping market, and then to study imbalance of supply and demand situations in shipping on crisis, and next, to analyses paradoxical aspects traced. Results - Shipping market is a volatile and cyclic characteristics, and its situations have to be examined very carefully. Since financial crisis has broken up in 2008, it is natural to think that world trade volumes has reduced rapidly, which means demand for shipping service has fallen, and accordingly, tonnage should be stagnated as well. However, shipping companies have put capacity into market as unexpectedly. This is because of economy of scale and time lag. Here, this can be explained in terms of paradox that is proved in this paper. Conclusions - From careful research in this paper, it is found that supply and demand are not always got along with market situations, in other words supply side could be working well, in spite of depression time of demand situations in world shipping markets.

Purpose - The purpose of the paper is to examine shipping markets exposed on severe competition after Lehman Brothers crisis in 2008, and look for some alternatives to get it over. Research design, data, and methodology - The research method to be applied is first to look into world economic situations, and then to investigate supply and demand of shipping markets, and strategic alliances as alternatives, which lead to some implication and lessons. Results - After the fierce world economic situations after Lehman Brothers crisis in U.S, it has shown that world economic output and growth is not like that of previous years. It is periods of new normal. Then, shipping has been influenced by less trade volumes and, however, shipping capacity has reached to overcapacity in supply terms. Therefore rates down is clear, and it should be needed new way of getting it over market situations. In this sense, strategic alliance is answer for overcoming difficult markets. Conclusions - From the careful look at all situations, such as world economic situation, supply and demand of shipping market, deep understanding for strategic alliances of shipping, it has reached to conclusion that strategic alliance is only answer for difficult shipping markets.
