S-Mode is a concept involving a standardized navigation display with accompanying standardized functionality and interfaces for navigational equipment. It was proposed by the International Federation of Shipmasters' Associations at IMO NAV $54^{th}$ session in 2008. The IMO e-Navigation Strategy Implementation Plan(SIP) addresses, S-Mode and the IMO MSC at its $95^{th}$ session in 2015 approved an output 1 to develop S-Mode guidance. In this study, it has been carried out survey of user needs for adopting S-Mode guideline on ECDIS which is core navigational equipment. It is conducted with a questionnaire survey, targeting deck officers and masters who will be the primary users of the equipment related to the e-Navigation system. In this research, users' opinion survey regarding the necessity of development, the scope of standardization, and priorities was conducted. This survey result could be contributed to development S-Mode guideline and specify the concept of S-Mode. It would be derived from standardizing component through providing elements to be considered for its development.

During the last 5 years, maritime safety navigation with IT has been a big issue. After the International Maritime Organization defines the e-Navigation strategy, various information on board can be integrated by their needs and aims. Especially, on-board information monitoring might use the single integrated display under consideration of user convenience. To do this, this paper suggests a user interface design guideline based on definition and analysis of the integration requirements and the existing commercial product.

In the IMO COMSAR 10th meeting, the SOLAS performance standard draft for Long-range Identification and Tracking(LRIT) was submitted to MSC. '81 meeting for its approval. The LRIT and AIS would provide an important data in monitoring SOLAS vessels at shore. This paper aims to suggest the vision and future directions for a successful E-navigation development in co-orporation with vessel monitoring.

Recently, safety-critical aviation system development programs promoted domestically have been terminated in the middle stage or they have not been put to practical use at the final stage. The program failure may be caused by various factors, but this study focused on imperfect test and evaluation(T&E) procedures. In general, T&E process of a safety-critical system must be distributed throughout the entire life-cycle of the system, have a continuity in phases, and can be implemented in a variety of ways depending on the maturity of the system development and acquisition strategy. This paper aims to present a new strategy by analyzing the domestic and overseas T&E processes to reduce the risk of domestic safety-critical CNS/ATM system development program and increase the success rate of program. First, we discuss the verification and validation techniques for safety-critical systems, analyze the T&E procedures of advanced institutes and the domestic situation, and then compare the domestic and overseas T&E processes to complement the imperfect testing procedure.

The IMO e-navigation strategy has requested a communication infrastructure providing authorized seamless information transfer between stakeholders. The Maritime Cloud is the term used to describe the concept of an infrastructure that support authorized, seamless information transfer, adding those elements, that are necessary to support the e-navigation domain. It is necessary to consider the study on maritime cloud security, but the study is still an early stage. In this paper, we propose a secure synchronization method for the maritime cloud services. The proposed method can be synchronize between the vessel based on the SH-Tree, and it has the advantage that there is no exposure information in the synchronization process.

e-Navigation strategy IMO promotes is defined as it is necessary to network to provide various maritime safety information to in land and on board users, and it is expected to provide a large amount and diverse kinds of maritime spatial information services to them frequently. However, as there are some limits to transmit that by current mobile maritime communication technologies, it is required to simplify and optimize the information. In this study, tree node and convex hull method is applied to S-100 SD spatial information to generalize and we arranged the efficiency and effect of generalization by storing in XML form which can be used in general.

Maritime Cloud has been progressed by IMO as a part of the e-Navigation Strategy Implementation Plan. Development of maritime cloud enables safe and reliable information exchange among maritime stakeholders. The research conducted static analysis of open source-based maritime cloud for design and development of e-Navigation application service. As a result, configuration and role of component of MMS, one of core technologies of maritime cloud, was found out. Also, in order to grasp maritime cloud-based application, we found operation process and relationship between maritime cloud and client by analyzing EPD. The findings of the research could be utilized for developing future e-Navigation service.

The International Maritime Organization's e-Navigation strategy is to introduce new technologies to ships to support easier and safer navigation. With the e-Navigation strategy, various equipment will be installed in vessels and the system structure will be linked to onshore systems. For this reason, a common data structure between systems became necessary, and finally the S-100 standard developed by the International Hydrographic Organization was selected. This paper describes a design of marine casualty data model based on the S-100 standard. The data model of the S-100 standard is designed in the form of a UML class diagram, and the final encoding follows the GML / XML format. We will look at the S-100 standard and product specifications under development, and describe the S-100 standards-based data design and portrayal definition of marine accident data.

However, as there are some limits to transmit that by current mobile maritime communication technologies, it is required to simplify and optimize the information. In this study, tree node method is applied to ENC using Douglas-Peucker algorithm and we arranged the effect of simplified spatial information through CALS method which compensates the defect of basic tree node method.

This study aims to enhance Korea's competitiveness by taking the lead in the international standardization and relevant global market. This is to be achieved by performing the role of First Mover through the resolute investment from Fast Follower that is servile to the decision of the organization in the e-Navigation strategy that has been promoted by the IMO. The study methodology is an integrated approach. It is established by modelling LSCM G2B2C2 Platform in maritime safety/security logistics and applied to the enhancement of maritime safety/security in global LSCM. This paper externally contributes to the reduction of world maritime accidents and exalt the national prestige; internally, the enhancement of the national competitiveness through the improvement of shipping port logistics and others. These eventually contribute to Korea's economic development that is combined by both theory and practice and of practical use of the integrated approach.
