In 1969, Y.J. Yun wrote the terrestrial navigation text book that discussed earth sciences, aides to navigation, chart and publications, tide and tidal current, piloting, rhumb-line sailing, great circle sailing grounded on the hand-on background and theory. It has still been used as a principle text book in a lot of maritime academies and schools. And many contents and definitions came from other terrestrial navigation books published in the United States of America, the United Kingdom, and Japan. But some of them have caused the misunderstanding because they had no enough explanation and explained by incorrect items. In this study, we have found out the problems in the terms course and heading which are related with the direction of the vessel movement, and proposed the amended definitions in order to prevent the misunderstanding and confusion. of them.

The pilot GOBT program was carried out from November 17th - December 17th 2021 at KIMFT; self-isolation for 10 days, Basic Safety Training(BST) for 5 days and 2 weeks of on-board training(OBT) were conducted during the period. Total 20 cadets from 5 different Countries were participated under the financial support of IMO ITCP and Korean ODA program. The program aims to provide capacity-building courses focusing on on-board training and assisting future maritime officers in meeting the minimum standard of seagoing experience in accordance with the STCW Convention. In the meantime, the program itself can serve as a platform to share best practices of how the training including the curriculum can be organized on specialized training vessels. The questionnaire survey was carried out to evaluate the GOBT program, and the overall average score was 96.4 points which seems that the cadets were very satisfied with the Global On-Board Training program provided by KIMFT in 2021.

With the rapid increase in the quantity of goods transported worldwide, companies are now started to show great interest in unmanned automated warehouses along with related research and development due to the increase of warehouse efficiency and reduction warehouse manpower. In a number of small warehouses, shuttle rack-based layouts that can handle inventory flow flexibly. However, the shuttle rack-based logistics center does not operate in case of emergency situations (faults, power outages, etc.), which seriously affects the efficiency and inventory management of the entire logistics center. Accordingly, in shuttle rack-based logistics center, we have classified various shuttle passages and RTV passages by layout and have analyzed its characteristics and types, along with derived reliability for each layout. The loading rate was also derived differently according to the number of passages, and have compared and analyzed reliability and loading rate for each layout.

In this study we briefly introduce the electronic float system based on the GPS and RF communication technology and present some field application results. The system is capable of operating 15 floats simultaneously for making discharge measurement. Since the electronic floats (EFs) acquire flow paths, they can improve velocity measurement accuracy up to 10%. Additionally, measured velocities by the EFs show good agreement with those by an ADCP. Relative difference in sub-section area calculated by the electronic and conventional float methods is -79~71% and, due to convergent tendency of floats flowing along near banks, it increases much larger. It is possible to improve accuracy up to 5~6% in making discharge measurement by the electronic floats at site with irregular flow paths and section arrangement. The electronic float system is capable of calculating more accurate velocity and section area using position information based on GPS. By real-time measurement of velocity, cross-section area and discharge, the electronic float system is expected to reduce manpower and improve accuracy, rapidity and efficiency of flood discharge measurements.
