In recent years, the transportation sector has been undergoing very rapid and multifarious changes due to the M&A, alliances between shipping companies, introduction of larger container ship as it cost reduction measure and the application of integrated logistics to satisfy the needs of customers. Therefore, container terminal is required adequate terminal facilities, sufficient channel depth, efficient handling and low cost of port fees and dues. The purpose of this paper is for functional assessment of efficient container terminal. Firstly, the container operating process information about yard equipment and chassis is extracted through the analysis of practical daily work report of container terminal. Also, the formulae of skill factor and troubles of operator on transfer crane are defined. Lastly, container handling simulation model which consideration of skill factor and trouble of operator is proposed by Petri network model.

Recently, the on-board equipments of vessels are getting diversifications with high technologies. With changing the trends, the shipboard network is turning to the light-weight ethernet architecture for integrated data management. For that necessity, this paper covers a development of the gateway system which gathers and processes the measured analog or NMEA data from loaded equipments to convert the messages based on IEC 61162-450 (standard for light-weight ethernet network of ships) in engine parts of small vessel. To do this, we analyzed the requirements for standardization of ship's equipments and related studies. To solve the problems of existing equipments, we defined the additional data formats (sentence formatter), developed the gateway system, and verified the utility of the developed system. Consequently, we established an interfacing framework for management and application of the generated data based on the ethernet in vessel.

The aim of this review is to provide perspectives on the application of remote sensing techniques for observation of marine environmental changes on various spatio-temporal scales. Currently available remote sensing technologies are reviewed and future direction is suggested. For better utilization of remote sensing, a comprehensive plan should be developed by a demand-side and problem-solving approach. Marine environmental changes should be observed on proper spatio-temporal scales where the processes occur. For appropriate observation and monitoring of various environmental changes in coastal regions, more sensors must be utilized. Platforms other than satellites should also be utilized to expand the spatio-temporal scales of observation. Calibration/validation activities, required for accurate interpretation of remotely sensed data, could utilize buoys and ship-of-opportunity sensors. It is desirable that such systems by developed as a part of an integrated monitoring network.
