With the development of the 4th industrial revolution technology, smartization in various fields is accelerating. The shipping and logistics industry is also promoting smartization by combining advanced new technologies such as digital twin, Internet of Things, and artificial intelligence. In Korea, the Ministry of Maritime Affairs and Fisheries is promoting a strategy to spread the smart shipping logistics system in line with the changing global shipping logistics trend, and through this, it is creating a foundation for smart shipping logistics. This study aims to present the concept of a communication tool that recognizes the importance of communication between each logistics entity and exchanges opinions between logistics entities in a virtual digital twin environment to cope with the changing shipping logistics process. In addition, for the development of these communication tools, this study derive a software design model, including architecture.

In this paper, we developed a Smart Heat Radiating Sheet(SHRS) having the absorption ability of more than 15 dB, and thermal conduction rate more than 20 W/mk for port logistics RFID(Radio Frequency IDentification) system by using AMP(Amorphous Metal Powder) and shielding sheet. Firstly, the EM(Electro_Magnetic) wave absorber samples were fabricated by using AMP and CPE (Chlorinated Polyethylene) with different composition ratios of 80 : 20 wt.% and 85 : 15 wt.%, respectively. Secondly, we fabricated the Smart Heat Radiating Sheet using the shielding sheet to attach EM Wave Absorber. As a result, the Smart Heat Radiating Sheet with absorption ability of 16 dB at 433 MHz and thermal conduction rate is 24 W/mk has been developed with the composition ratio of Amorphous Metal Powder : CPE = 85 : 15 wt.% and thickness of 5.5 mm.

Recently, interest in smart port systems for linking with autonomous ships is increasing. To build a smart port system, primarily, a system that can automatically moor a vessel is required. To calculate the allowable mooring capacity of the automatic mooring system in a port, the characteristics of the vessel must be considered, and the external force generated from environmental disturbances in the sea must be accurately calculated. Accurately estimating the magnitude of these environmental disturbances is an extremely important factor for designing an automatic mooring system. In this study, the mooring capacity of the HANBADA was estimated according to the port and fishing port design criteria of the Ministry of Ocean and Fisheries. The longitudinal and lateral forces of the mooring force acting on the HANBADA were 18 kN and 248 kN, respectively, under the most extreme ocean conditions (BF 6).

In this study a smart HDMI switch is proposed to detect newly formed video stream and automatically change the transfer path to the corresponding port without pulling the HDMI plug and putting it again in the desired port manually and physically. Furthermore the proposed switch is designed in the advanced wireless video transmission scheme based on millimeter band technology. The proposed system shows its feasibility by the hardware experiment in the full-HD video transmission performance including the function of the smart port change.

This study examines the level of port service quality based on $Gr{\ddot{o}}nroos$(1984)'s Two-Dimensional Model: we investigated service-environment quality and service-delivery quality, and added service-product quality as a process quality. This study focused on a service user like a llner, forwarder, shipper, or a logistics firm using port service in the Port of Busan. We investigated relationships among the following vairables: service quality, customer satisfaction and port image; we also analyzed the path coefficients using Smart-PLS 3.0. The results and suggestions of this study are summarized as follows. First, all of the service quality variables influenced customer satisfaction but service-delivery quality didn't have an impact on port image. Secondly, there is correlation between customer satisfaction and port image; customer satisfaction had a positive effect with port image. Lastly, customer satisfaction and port image influenced the Relation Continuity Intention.

The changes caused by the 4th industrial revolution are accelerating the convergence of technologies due to the COVID-19 Pandemic. As a result, rapid changes are expected in various fields of society and industry. The shipping and logistics industry is also in urgent need of smartization due to changes in environment and technology. However, in the case of Korea, the smartization of shipping and logistics technology is insufficient compared to that of advanced countries. For smartization for complex business processing with many related entities, smooth communication and visual confirmation using the latest technologies are becoming important. Such visualization and communication will become more important in smart shipping and logistics This study intends to present an integrated communication tool between self-driving ships and container terminals for the realization of smart shipping and logistics. In particular, a study was conducted on the development of a digital twin-based communication tool that satisfies the requirements of ship berthing and loading/unloading operations in which various actors participate and process complex tasks.
