Recently, international society strongly concerns global green house effect. As a result each nation introduces green policy for their economy and sustainable development. The emissions of carbon dioxide come from various sources, such as ports and port activities. Especially, port is a logistics hub for shipping, road and railways. Therefore, successful reduction of emissions in the port may encourage other transportations to reduce emissions. Korea as developing country is excused from Annex I countries which committed themselves to reduce four greenhouse gases. However, Korea is going to be placed in Annex I countries in 2013. Korean economy is heavily dependent on international trade and especially, 99.8% of its international trade cargoes is transported through the ports. Therefore, Eco-port plays a very important role in future Korean sustainable development. By introducing the most advanced port pollution regulations, Japan has taken a immediate step for Eco-port policy. International trade is very significant in Korea as well as in Japan, both nations have similar industrial structure. Therefore, Korea should pay attention to Japanese Eco-port policy and activities. This paper examines Japanese Eco-port policy and its' implications in order for Korea to find the most efficient way to reduce the emissions as Korea should reduce greenhouse gas emissions in post kyoto system.

With the development of the 4th industry, the logistics industry is evolving into a smart logistics system. However, ship work that transports vehicles is progressing slowly due to various problems. In this paper, we propose an stowage automation algorithm that can be used for cargo loading of vehicle carriers that shortens loading and unloading work time. The stowage automation algorithm returns the shortest distance by searching for a loading space and a movable path in the ship in consideration of the structure of the ship. The algorithm identifies walls, ramps and vehicles that have already been shipped, and can work even with randomly placed. In particular, it is expected to contribute to developing a smart logistics system for vehicle carriers by referring to the ship's master plan to search for vehicle loading and unloading space in each port and predict the shortest movable path.

According to the increase of container flows and the appearance of large-sized container vessels, the container handling equipment in ports is evolving continuously. This research introduces the simulation model for evaluating in detail the mechanical productivity of container cranes. The model considers a single trolley and dual trolleys as the mechanism of a container crane and a single lift, a twin lift, and a tandem lift as the spreader type of it. Additionally, the detail specifications such as the dimension and the speed of a container crane are inputted and the kinematic characteristics of it are simulated. The model also considers the size of a vessel, the storage position of containers in the vessel, and the weight of containers as external physical constraints. Experimental conditions can be configured conveniently because various parameters in the model are separated. Moreover, the model can accommodate flexibly new equipment types and the changes of the existing equipment because it is designed and developed in object-oriented concept.

In order to achieve a sustainable competitive advantage in the expanding maritime transportation market, most shipping companies are making every effort to reduce transportation costs. Likewise, the car shipping companies, which carry more than 80% of total car import and export logistics volume, also do their utmost for transportation cost saving. Until now many researches have been made for efficient maritime transportation, but studies for car shipping companies have rarely been made. For this reason, this study has tried to develop a maritime transportation planning support system which can help to save logistics costs and increase a competitive power of car shipping companies. To this end, instead of manual effort to solve the routing problem of car carrier vessels, this study has proposed a genetic algorithm. The performance of the genetic algorithm will be evaluated by comparing with the optimal solution of integer programming model.

This paper develops a framework of combining Balanced Scorecard (BSC) and Quality Function Deployment (QFD) using Analytic Hierarchy Process (AHP) and Analytic Network Process (ANP) and evaluates the performance factors of container terminals using the framework. This study designs a BSC of container terminals and then transforms this into QFD in order to determine the priority of performance factors. This paper provides a modified QFD model and shows a causal relationship among perspectives of BSC to find out critical performance factors of container terminals. This modified QFD model is different from traditional models in that a correlation and relation matrix is presented. This combination of BSC and QFD with AHP and ANP helps to create more realistic and accurate representation of QFD models.

The RFID technology has attracted much attention these days due to the far better efficiency than the bar-code and magnetic card system. As an important usage, the 433 MHz active RFID tag was already adopted to the container ports in the United States and Europe for container loading/unloading automation and equipment location. However, there is one problem to be solved for the complete automation. RFID readers support only the direct communication with tags within their RF communication range. Then there are a lot of containers and equipments such as crane, yard tractor, and forklift in ports; and because they are made of metal, they interfere the RF communication, resulting in the occurrence of the dead-zone. In the dead-zone, RFID tags cannot receive any signal from readers. There may be several solutions to resolve the dead-zone problem. Among them, this paper suggests the most economical solution where RFID tags in the dead-zone can communicate with readers via neighbor tags in the multi-hop manner The new RFID communication architecture should be carefully designed in order to maintain the compatibility with the previous standard. Our experiment shows that the proposed architecture works well even in the case where some tags are out of the RF range of reader.

The labor contract Law has been prepared as an important solution for social stability. After long disputes around the orientations of the law, On June 29, 2007, the new Chinese labor contract law is passed. This law reflects the changing labor relations because of economic reforms like restructuring of the state-owned enterprises and so on. This law contains more market-oriented clauses that are supplemented by corporatist scheme supported by trade unions than the first draft. This law emphasize labor's rights and interests to remove prior labor contract problem. So Chines government see this law as standard law to restructure social relationship and also require firms to corporate social responsibility. Therefore, implementation of the new Chinese labor contract law bring about increasing labor cost, infringement of autonomy for human resource management, rigidity of industrial relations. Under these situation, Korean shipping and port logistics companies need to introduce management system of minimized employment, prepare human resource management in response to long-term employment, maintain favor relationship with trade union, and set up counteiplan about risk of a labor dispute.

The purpose of this study was to assess the current status of cyber security at the Busan Port container terminal and derive strengthening factors through exploratory research. In recent years, the maritime industry has actively adopted Fourth Industrial Revolution technologies, resulting in changes in the form of ports, such as automated and smart terminals. While these changes have brought positive improvements in port efficiency, they have also increased the potential for cyber security incidents and threats, including information leakage through cargo handling equipment and ransomware attacks leading to terminal operations disruption. Especially in the case of ports, cyber security threats can have not only local effects within the port but also physical damage and implications for national security. However, despite the growing cyber security threats within ports, research related to domestic port cyber security remains limited. Therefore, this study aimed to identify factors for enhancing cyber security in ports and derive future enhancement strategies. The study conducted an analysis focusing on the Busan Port container terminal, which is one of the leading ports in South Korea actively adopting Fourth Industrial Revolution technologies, and conducted a survey of stakeholders in the Busan Port container terminal. Subsequently, exploratory factor analysis was used to derive strengthening factors. This study holds significance in providing directions for enhancing cyber security in domestic container ports in the future.
