The purpose of this paper is to suggest the development of the Guidelines on VTS English language competency test, according to IALA Guideline 1132 - VTS Voice Communications and Phraseology. As the foundation for improving VTSOs' communication capabilities throughout their career lifecycle in terms of training, accreditation, and revalidation, a development of a VTS-specific language testing system with explicit language testing evaluation criteria becomes more critical. With the aim of facilitating the discussion, a range of suggestions to be considered in the development of Guidelines on the VTS English competency test are made

Route Design & TSS(Traffic Separation Scheme) establishment are often used to improve the marine traffic safety in the heavy waters. There are several domestic and international route design guidelines, but there is no guideline of TSS design. So, TSS is designed by specialist's subjective opinion. Until now, when TSS is designed there are a few paper about the easiness effectiveness of marine accident, but there is no paper to design TSS guideline. This paper proposes the design guideline about TSS to improve the safety of navigation vessel by the quantitative assessment in the viewpoint of mariner.

IALA Guideline 1132 is intended to assist authorities in implementing the procedures described in IALA Recommendation R1012: VTS Communications with the objective of harmonizing VTS communications through the use of standard message structure and phraselogly. For this reason, it is recommended that VTS Authorities put adequate procedures in place to ensure its consistent and correct implementation for the actual VTS operation as is now being considered in IALA as part of the VTS English language proficiency test. In light of the 2022 publication of IALA Guideline 1132: VTS Voice Communications and Phraseology, in this sense, the potential evaluative variables will be studied in the context of this presentation.

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.

This paper describes the theoretical background and detailed structure of Navi-HEGS (Navigation system Human factors Evaluation and Guideline System) which has been developed for the human factors and HMI(Human-Machine Interface) researches for a CNS (Car Navigation System) and a digital map. Navi-HEGS is and integrated system that consists of a digital map UIMS(User Interface Management System), a CNS simulator, various evaluation tools, and a design guideline system. If Navi-HEGS is properly applied and utilized, it is possible to extract the substantial users requirements and preferences of a CNS and a digital map and then, these requirements can be simulated and evaluated with various human factors evaluation techniques. Applications of Navi-HEGS can improve the CNS usability, drivers safety and performance that directly affect the success of ITS(Intelligent Transport System). Also, results can be used as the basic data to establish the standards and design guidelines for the driver-centered CNS design.

The e-navigation in IMO(International Maritime Organization) has been developed as a strategy for user oriented service followed by HEAP(Human Element Analysing Process) to assess the solutions in view of human ergonomics. Although IMO already had an interim guideline for human element assessment, it did not include appropriate human elements for user-oriented assessment, therefore there should be a need for revising the human elements of current guideline for ergonomic assessment of e-navigation. We have developed user-oriented human element checklist, threat elements caused by human external condition and error elements originated by human itself in line with the e-navigation development concept of user-based approach.

The Navigation Streets Map that directly supplies information for a driver plays an important role in Car Navigation System(CNS). Therefore, cause the compatibility, preference, visibility, and readability of the navigation streets map will be hold sway over driver's information acquisition, safety, and performance in CNS, it is important that designer's requirements should be analyuzed for ergonomic design of navigation streets map. Especially, there are differences between the topographical objects marking method and that of the general map in a navigation streets map. Because much information is marked in a narrow space, it is important that the text information should be done in navigation streets map. Also, because it is a important factor to mark the text format for the marking method of the topographical objects, the design requirements will be drawn out through the factor analysis for the text marking method. And when ergonomic designers are doing, this result will be basic research for developing driving simulator of CNS and it will be a ergonomic guideline of navigation streets map.

The paper deals with integrated navigation and sense & avoid systems for small unmanned aerial vehicles (UAV). First an introduction to the current UAV activities of the institute is given. It is followed by an overview about the integrated navigation system developed for small UAVs. The system is based on a tightly-coupled GPS/INS architecture. But instead of using delta-ranges, time-differenced carrier phases are used to aid the INS. Finally, results from navigation filter validation in flight tests are presented. After that an overview about sense and avoid strategies for application in small unmanned aircraft is given. From this a guideline for developing such a system for the institute's UAVs is presented.

This paper describes the path planning method in an unknown environment for an autonomous mobile robot equipped with CCD(Charge-Coupled Device) camera. The mobile robot moves along the guideline. The CCD camera is useful to detect the existence of a guideline. The wavelet transform is used to find the edge of guideline. Using wavelet transform, we can make an image processing more easily and rapidly. We make a fuzzy control rule using image data then make a decision the position and the navigation of the mobile robot. The center value that indicates the center of guideline is the input of fuzzy logic controller and the steering angle of the mobile robot is the fuzzy output. Some actual experiments for the mobile robot applied fuzzy control show that the mobile robot effectively moves to target position.

Inertial navigation error is the major source of miss distance when only the inertial navigation system is used for guidance, and tend to monotonically increase if the flight time is small compared to the Schuler period. Miss distance due to these inertial navigation errors, therefore, can be minimized when a missile has the minimum time trajectory. Moreover, vertical component of navigation error becomes null if he impact angle to a surface target approaches to 90 degrees. In this paper, the minimum time trajectories with the steep terminal impact angle constraint are obtained by using CFSQP 2.5, and their properties are analyzed to give a guideline for he construction of an effective guidance algorithm for short range tactical surface-to-surface missiles.
