The world's container cargo trading is increasing daily, and the role of the container terminal is becoming more important as the center of cargo transportation. In Japan, new container terminals being constructed face very severe competition with larger, cheaper terminals so they must handle cargo more efficiently and cheaply. To cope, handling systems such as container cranes, yard cranes, and conveyers are being automated to enable unattended operation unloading and loading schedule planning, etc., are being computerized. In these system, crane automation and control computerization are already generalized, but automatic control of container conveyers is not completed yet. The container conveyer -15m long, 4m wide, and 1.5m high - picks up containers from container ships with a container crane and hauls them to the shift yard for release to the yard crane. Both crane are operated automatically, so the conveyer must stop at the desired position within a permissible error of ±7.5cm, and run on a predetermined course and speed. Collision avoidance is required because many vehicles oparate on the same course. The automated guided vehicle (AGV) system, which is diesel-driven, 4WS and 4WD, was thought to be effective, but container weights very widely, as do road conditions which depend on weather, so conventional control is not sufficient to maintain the required accuracy. We applied learning control to maintain the desired course and for stopping at the desired position. Speed was controlled, conventionally. The system's applicability was confirmed with computer simulation and vehicle performance testing. This system will be used at the Kawasaki container terminal in 1999 and we are currently working on improving performance.

Sustainability accounting is an emerging research area receiving growing awareness. This study examines the role of digital technology in manufacturing companies’ sustainability accounting. To guide the research, we use a triple layered business model canvas, which supports the accounting of a manufacturer’s performance for the economic, environmental, and social aspects of sustainability. We present an explorative case study of four Norwegian manufacturing companies representing different industries. The findings from the study indicate that while accounting for economic values is well taken care of, companies do not perform comprehensive environmental and social accounting. Furthermore, we observed a shift from a focus on sustainability issues related to the internal manufacturing process to a focus on sustainability issues for the life cycle of the product. Even though the manufacturers are at the forefront with regard to automation and control of production, with extensive use of robots giving a large amount of data, these data are not utilized towards sustainability accounting, showing that sustainability and digitalization are seen as two separate phenomena. This study sheds light on how digital data available from applied Industry 4.0 technologies could enhance sustainability accounting with limited efforts, linking sustainability and digitalization. The results provide insights for manufacturers and researchers in moving towards more sustainable operations and products.

The COVID-19 pandemic had a serious impact on global trade in 2020. The interruption of the supply chains due to various restrictions influenced the rapid drop in the transport demand. In the last decade, the global containerized trade has noted the growth of approximately 55,5%, with an average pace of growth of about 5% yearly. Container shipping, as one of the industries vulnerable to economic shocks, has noted a significant drop in trade. The role of maritime container terminals as an integrator and facilitator of global trade in the global supply chains is undisputed. Therefore, the role of services provided by the maritime container terminals has grown in importance. This situation generates the necessity to adapt to these circumstances in a way that expresses the need of improving the service quality, as one of the key aspects of competitiveness. The purpose of this paper is to determine the possibility to verify the relation between COVID-19 impacts on maritime container transport and maritime container terminal service quality. Based on the findings the suggested actions for service quality improvement are proposed.

This article presents the most valuable and applicable open-source tools and communication technologies that may be employed to create models of production processes by applying the concept of Digital Twins. In recent years, many open-source technologies, including tools and protocols, have been developed to create virtual models of production systems. The authors present the evolution and role of the Digital Twin concept as one of the key technologies for implementing the Industry 4.0 paradigm in automation and control. Based on the presented structured review of valuable open-source software dedicated to various phases and tasks that should be realised while creating the whole Digital Twin system, it was demonstrated that the available solutions cover all aspects. However, the dispersion, specialisation, and lack of integration cause this software to usually not be the first choice to implement DT. Therefore, to successfully create full-fledged models of Digital Twins by proceeding with proposed open-source solutions, it is necessary to make additional efforts due to integration requirements.

Port is one of the supporting infrastructure of sea transportation which is the gateway to and out of goods and passengers. The function and role of the port is very important one of them is the container terminal. The container terminal is where loading and unloading of goods in containers. At the container terminal the length of loading and unloading process is determined by the quality and quantity of the tool. One of them is container crane. Therefore designed a container crane model in the form of a prototype named electric container crane. At the time of design is used Programmable Logic Controller (PLC) Omron brand CP1E-E20SDRA type as a safety controller and add a double trolley system so that container cranes can be flexible in 4 slots without gantry movement, and also add automatic cable track system so container crane can be Moving without the need for a portable generator because it is supplied directly using electricity from PLN

The Liner services provides regular shipments of goods between ports within the set timeframe. A fixed route, the obligation of receiving cargo and to go to sea with established schedule distinguishes line service from the sea transportation of bulk cargo. Containerization, establishment and improvement of routes and infrastructure helped liner shipping to become the driving force of Global economy, which supports the growth of international trade, development of different business forms such as mainly small and medium sized businesses. The shipment volume of containerized cargo was 37.1 M.TEU in 1994, by 2020 the figure reached up to 143.3 M.TEU. This indicator was growing at a high rate on East-West route during 1990-2016; In terms of North-South, South-South and intraregional route same measure was high between 1990-2004 years. Afterwards, Abovementioned growth has become more stable. Containerization changed the structure of Liner fleet. If general cargo vessels deadweight was growing during 1970-2010 (From 40.5M Dwt to 99.7M Dwt), in the latest 10 years, the tonnage has been decreasing and as for 2020 it was 74.6M Dwt. In exchange for this the number of container ships have been growing consistently and in 2020 it consisted of 274.7M Dwt. Maersk became the largest line operator since 2001 (with a market share of 9.4%) and by 2020 it’s share of the business has grown to 17%. The company owns container terminals worldwide, including the Poti container terminal. MSC is on second place (9.4% market share), COSCO is on third place (12.4%) and CMA CGM takes forth place (11.8%).

This study introduces the concept of microgames to support situated learning in order to foster situational awareness (SA) of planners in seaport container terminals. In today's complex working environments, it is often difficult to develop the required level of understanding of a given situation, described as situational awareness. A container terminal represents an important, complex node in the multimodal transportation of goods. Many operations have to be planned in order to ensure a high performance of the whole system. To evaluate the relation between SA and planning task performance, the authors conducted tests with 142 participants. They evaluated the role of SA in integrated planning activities, and the playability and usefulness of the microgame. In conclusion, the authors can state that SA is very conducive to integrated planning tasks in container terminal operations. The microgame approach allows for an enjoyable game activity, while providing a meaningful situated learning experience towards SA.

In continuing studies on the role of viruses in biochemical transformation, Dr. Munyon has succeeded in isolating a highly infectious human herpes virus. Fluids of buccal pustular lesions from Sasha Munyon (10 mo. old) uiere introduced into monolayer sheets of human embryonic lung (HEL) cell cultures propagated in Eagles’ medium containing 5% calf serum. After 18 hours the cells exhibited a dramatic C.P.E. (intranuclear vacuoles, peripheral patching of chromatin, intracytoplasmic inclusions). Control HEL cells failed to reflect similar changes. Infected and control HEL cells were scraped from plastic flasks at 18 hrs. of incubation and centrifuged at 1200 × g for 15 min. Resultant cell packs uiere fixed in Dalton's chrome osmium, and post-fixed in aqueous uranyl acetate. Figure 1 illustrates typical hexagonal herpes-type nucleocapsids within the intranuclear virogenic regions. The nucleocapsids are approximately 100 nm in diameter. Nuclear membrane “translocation” (budding) uias observed.
