This paper presents a mathematical formulation for container slot chartering model through strategic alliance between liner shipping companies. This paper develops a solution procedure to apply the model to real world problems and its applicability is demonstrated by a numerical example. The model presented in this paper has some important features which have never been considered in the previous researches. The model is linear model and pursuits profit maximization. And also it considers slot chartering capacity selection. This paper attempts to perform sensitivity analysis and compares slot chartering model with basic non-collaborating model in which there is no alliance and collaboration. As a result of sensitivity analysis, some interesting findings are obtained; Even though freight rate is more and more decreasing, the profit by slot chartering model is always higher than the basic model but the profit gaps become smaller. But The ratio of the profit gap to the profit of basic model is more increasing.

Korea has set up a radiation emergency planning zone based on the 「Act on Physical Protection and Radiological Emergency」 to protect residents living near nuclear power plants in the event of nuclear disasters. Little research has been conducted on the appropriateness of existing nuclear evacuation facilities because of a general lack of interest in nuclear accidents. This research addresses this gap by analyzing the location adequacy of evacuation facilities in Busan's emergency protection planning area based on vulnerable populations and accessibility analyses. The Gijang-gun which has the greatest risk, shows that only 4.05% of the total urban area was included in the evacuation service area within 5 minutes while only 36.93% of Geumjeong-gu and 37.23% of Haeundae-gu were included in the evacuation-enabled area. In addition, evaluation facilities in the elderly population hotspots were lacking, and there was a wide gap between dongs within the same Gu. Thus, additional evacuation facilities need to be designated and installed considering the spatial equity between areas and safety of both the public and vulnerable populations.

The fundamental endeavor of this study is to investigate the asymmetric relationship between bunker price and Baltic Dry-bulk Index (hereafter BDI). Previous investigations employ linear form based analysis between oil price and BDI but we develop nonlinear and asymmetric cointegration method, which is properly able to capture the decreasing and increasing periods differently. The empirical results show there is no relationships in linear model (e.g. Engle and Granger's methods). On the contrary, our estimate reveals there is significant long-run relationship with asymmetric framework, which implies the necessity of nonlinear and asymmetric consideration to the bunker price analysis.

This study aims to review Russia's annexation of Crimea from a maritime security perspective. Based on a comprehensive analysis of Russia's national security perception, this study analyzed Russia's maritime security strategy and the security importance of the Black Sea and the Sea of Azov, and reviewed the annexation of Crimea from a maritime security perspective. The main argument of this study is as follows. Russia's annexation of Crimea was necessary for the successful fulfillment of Russia's maritime security strategy in the Black and Azov Seas. Russia's annexation of Crimea guarantees the activities of the Black Sea Fleet militarily from a maritime security point of view, secures a passage to the Atlantic Ocean to counter NATO's expansion. From a economic security point of view, Russia's annexation of Crimea was based on the strategic considerations to secure influence within the Black Sea economic bloc which guarantees stable production and transportation of natural resources and shipping.

While maritime arbitration industry has not been prevalent in Korea, Korea ranked fifth in terms of export volume and its shipbuilding industry ranked top globally in shipbuilding order volume in 2020. The discrepancy between the maritime industry's productivity and relative lack of maritime arbitration has had a negative impact on Korea's economic development. To address these problems, this paper i) reviews preceding research, ii) examines the Korean maritime arbitration system's status and analyzes the KCAB's maritime arbitration statistics from 2005-2020, iii) examines major foreign maritime arbitration institutions' status and strategies including LMAA, SMA, SCMA, and HKMAG, and lastly iv) suggests practical ways to promote maritime arbitration in Korea. The Suggestions for promoting maritime arbitration are 1) to prepare and promote various maritime standardized forms for the Korean shipping industry, 2) to insert an arbitration clause in medium and large-size Korean shipping firms' B/L clause, 3) to expand professional maritime manpower training and other infrastructure, and 4) to enhance the predictability of the result of arbitration through maritime arbitral awards or by examining the feasibility of the appeal system against the arbitral award only on a point of law in the future. In conclusion, the success or failure of promoting maritime arbitration in Korea depends on the will, passion, cooperation and practice of the most important key players in maritime arbitration, such as the Asia Pacific Maritime Arbitration Center (APMAC), the Korean Commercial Arbitration Board (KCAB) and the Seoul Maritime Arbitrators Association (SMAA).

In light of the significant increase in the quantities of goods transported and the development of the shipping industry, the frequency of usage of port structures has increased; yet, the government's budget for the shipping & port of SOC has been reduced. Port structures require systematically effective maintenance and management trends that address their growing frequency of usage. In order to construct a productive maintenance system, it is essential to develop deterioration models of port structures that consider various characteristics, such as location, type, use, constructed level, and state of maintenance. Processes for developing such deterioration models include examining factors that cause the structures to deteriorate, collecting data on deteriorating structures, and deciding methods of estimation. The techniques used for developing the deterioration models are multiple regression analysis and Markov chain theory. Multiple regression analysis can reflect changes over time and Markov chain theory can apply status changes based on a probabilistic method. Along with these processes, the deterioration models of open-type and gravity-type wharfs were suggested.

This study analyzes the results of applying the ISO19030 (hull and propeller performance monitoring method) standard to an actual 178 k bulk vessel. Recently, there have been many attempts to apply various energy reduction solutions to vessels to continuously strengthen GHG reduction regulations and secure maritime competitiveness. However, it is not easy to quantitatively analyze the performance of a ship. To resolve these problems, shipping companies, marine paint companies, ship owners, and transportation associations have appointed specialists and standardized the ISO19030 (standard of hull and propeller performance monitoring method) guidelines in 2016 after three years of continuous review. The ISO19030 standard provides methods to monitor hull and propeller performance quantitatively through standardized procedures, thus allowing ship managers to arrive at informed decisions for hull and propeller maintenance, and to evaluate energy-saving solutions and ship-maintenance efficiency. The ISO19030 standard provides a method of analyzing the ship's own performance by collecting the ship's operation and agency data and correcting its environmental and operating factors. In this paper, we apply the ISO19030 standard to three actual ships and propose the ISO19030 application result and the improvement point of the current ISO19030 standard.
