In recent years, an increase in deaths and injuries of port cargo handling workers, has raised the need for more effective accident management. The purpose of this study was to evaluate the accident risk for port cargo handling workers and assess ports with high accident risk within the Korean alternative ports using the Entropy & GRA (Grey Relational Analysis). To achieve this purpose, first, 11 Korean ports were selected and the evaluative factors for their outranking evaluation by brainstorming were extracted. Second, the Grey Relational Coefficient of 11 alternative ports was calculated using the GRA. This paper, finally, determined the priority orders of accident risk through calculation of the Grey Relational Grade as the link Grey Relational Coefficient method and the weights of the evaluative factors were calculated by using the Entropy method. In the proposed model, eight criteria such as cargo worker, old cargo worker, work hours, facilities environment, steel cargo volumes, cargo volumes, injury numbers, and death numbers were collected. Busan port was identified as highest accident risk port, and so it should be a top priority to develop a plan to mitigate the risk.

The purpose of this study is to suggest new methods for evaluating the benefits of a preliminary feasibility study for port construction. For this purpose, this study analyzes the problem of barge loading and unloading systems, and suggests new methods such as using neighboring same kinds of ports first. The study also estimates the benefits for ports that have been evaluated by the existing theory, using the newly suggested methods. The result suggests that there is a possibility to reduce the level of economic feasibility for both general and container-exclusive ports by applying the newly suggested methods.

As increasing of container throughputs, port business market in Korea has been developed. However, due to the introducing of a handling fee reporting system in 1999 and surplus of facilities, port business market in Korea turned into deadly competition with lowering the handling fee. Due to the reasons, the handling fee in 2015 declined as much as 50% of in 2000. Therefore, this study analyzed whether the handling fee decline caused consumer surplus in the port business market of Korea or not. To do that, this study applied a methodology of Alexander for estimating the consumer surplus and Hausman's model using Hicksian demand. As the result of the analyzing, due to the excessive decreasing of the handling fee compared the import & export demand, consumer surplus of the port business market in Korea was decreased. However, due to the exception of transshipment from demand in this study, transshipment demand is needed to be considered to estimate of economic value of port business market in Korea in the future. Also, economic value of port business including subsidiary businesses will be estimated in order to strengthen the method for estimating economic benefit of port construction.

The Port logistics is a pivotal industry in strengthening competitiveness for countries and companies and plays an important role in accounting for the majority of Korea's import and export volume, so its importance among Korea's industries is truly enormous. The port, which plays such an important role, is simultaneously unloaded, transferred into the dock, and stored, and it can be said that it is composed of a very complex flow. In particular, port unloading is an environment in which port unloading workers cannot escape the risk of disasters as large cargoes and cranes for container transport move, and numerous disasters are hidden and lead to serious disasters. Through literature studies on the Serious Accident Penalty Act, this study investigated how the Serious Accident Penalty Act affected port unloading workers and whether there was a change in satisfaction with safety education according to the enforcement of the Serious Accident Penalty Act. Through this study, it was found that port unloading workers were more aware of safety than managers in cognitive, attitude, and experience factors. Since the port unloading manager is not put into the unloading work, the perception of safety was analyzed to be lower than that of workers. Since managers should educate workers on safe work and be alert to safety, it seems that port unloading managers will also need to change their perception of safety. The Act on the Punishment of Severe Disasters took effect on January 27, 22, and in the early stages of the enforcement of the law, many confusing and ambiguous parts are found for those in charge of performing practical tasks on the front line until the law is settled. It seems necessary to revise the Act on the Punishment of Severe Disasters for the purpose of clear standards for the law and no safety accidents in the field to prevent confusion in work. In addition, in order to derive more meaningful research results in the future, it is expected that research on the perception of disasters by workers and managers will be continuously needed by deepening literature research to find various factors and using investigation methods such as interviews.

It is a critical problem of the Busan container cargo market that serious competition between the north port terminal and the new port terminal is weakening port of Busan's competitiveness. To avoid this serious competition, Busan Port Authority(BPA) has executed a cargo-rate approval system from last year. However if Busan's container terminal operators do not accept this system, the execution performance will be insufficient. Therefore, the purpose of this study is to test the effect of cargo-rate approval in the Busan container cargo market. To attain this research purpose, the current situation was analyzed and the existing papers were investigated. Therefore, cargo-stabilizing factors were extracted and the moderated effect between these factors and cargo-rate approval was tested. The results are as follows. First, three cargo stabilizing factors-(market structure, market behavior, and BPA)-appear to have a strong positive impact on the stabilizing effect; however, the factors that are handled by the operators can not influence the stabilizing effect. In particular, market behavior factors, such as cargo-rate dumping restriction, contributed to stabilizing cargo market. Second, The results appear to have a strong positive impact on the moderated effect as well as the cargo-rate approval. These research results show that the execution of cargo-rate approval is important in stabilizing the cargo market. Therefore, stabilizing the cargo market will contrubute to improving the image and bargaining power of the Port of Busan.

Recently several researches of high speed container ship and loading system are mainly accomplished in U.S.A. and Japan. Its shipping service is not realized but it is realized in near future. To effective use of the feature and efficiency of them, quay, loading/unloading. yard operation system, port management system and connection transport system must be well integrated and operated. Specially, loading /unloading speed of container crane is important for making effective use of them. To speed up loading/unloading system, RO-RO and LO-LO methods that are mostly exclusive system are studied on the container crane with special structure and mechanism to handle individual container or bundle of containers. In this paper these methods are shown. When new high speed loading system of container is desighed, the realistic constrains must be considered.

컨테이너 크레인은 대형구조물로써 차폐물이 거의 없는 항만에 설치되므로 풍하중에 의한 영향이 매우 크다. 또한 초대형 컨테이너선의 등장과 대형선사의 등장과 함께 항만하역장비도 대형화, 고속화, 자동화됨으로써 컨테이너 크레인에 작용되는 풍하중의 영향이 더욱 증가하고 있다. 이로 인하여 컨테이너 크레인은 강풍에 의한 재난사고 발생위험이 항상 존재한다. 이러한 사고를 예방하기 위한 기상 및 하중 통합 모니터링 시스템 장치의 개발이 필요하며, 이러한 장치를 개발하게 되면, 국내외 기존 항만에 사용되고 있는 하역장비에 바로 설치할 수 있으며, 차후 개발되고 있는 자동화된 하역장비에도 적용이 가능함에 따라 관련 산업의 발전에 크게 기여할 수 있을 것이다. 본 논문에서는 이러한 하중 통합 모니터링 시스템의 가장 기본이 되는 컨테이너 크레인의 각 레그(Leg)부분에 부착되는 간접부착식 로드셀의 하중과 치수사이의 관계에 대한 연구를 제시하고자 한다.

Container terminals keenly compete with one another because of the continuous increase of container flows and the appearance of large-sized vessels. Major cargo handling equipment manufacturers are interested in the development of new conceptual equipment to greatly increase its productivity. In this study, a two-phase procedure is suggested for selecting the optimal development alternatives, when various development alternatives for container cranes are given. The first phase removes the alternatives that violate essential requirements and the second phase selects final alternatives by the evaluation of experts and the linear assignment method. Finally, a case applying the procedure is provided.
