The ship building industry is experiencing a wave of new ship technology and design. Historically, ship design has been slow to change. For example, the mono-hull design has been around for centuries. Propulsion has evolved as technology advanced but we see ship owners as very conservative in embracing new advances. In the past 20 years this trend has shifted as new designs begin to appear. This article explores some of these changes and the drivers that are causing this shift. Clearly, as technology advances and uses for ships expand, the ship building industry design is evolving. New issues have come to the fore and have accelerated the design change. These drivers include fuel costs, reduced crewing, speed, security issues, pollution regulations, stealth needs, human factors, safety, geopolitical changes, multi-mission requirements, and acoustic quietness. Examples of military, commercial, and research ships are discussed.

In Denmark, the maritime engineering competences requested by the industry have changed in the past one to two decades. The typical naval architects do no longer find them selves working in the ship-building industry but rather in the industry of ship operators, consultancies, class societies, etc. This means that universities educating maritime engineers need to reflect the changes in the curricula for their maritime engineering students. Topics and issues regarding this matter have recently been addressed in a survey made in the Danish maritime industry. The survey concludes that the demand for maritime engineers in the industry is considerably larger than the output from the technical universities. Moreover, it sets forth a series of recommendations to the industry as well as to the universities to facilitate meeting the demand for maritime engineers in Denmark in the future. The recommendations are outlined together with work commenced at the Technical University of Denmark (DTU) to update the curricula for DTU’s maritime engineering students. Thus, DTU offers an education reflecting a large share of the recommendations in the curricula.

Since the 21st century, the concept of green building has been gradually popularized and implemented in more countries, which has become a popular direction in the area of sustainability in the building industry. Over the past few decades, many scholars and experts have done extensive research on green building. The purpose of this paper is to systematically analyze and visualize the status quo of green building. Therefore, based on Web of Science (WoS), this paper analyzed the existing knowledge system of green building using CiteSpace, identified keywords related to green building and their frequency of occurrence using the function of keyword co-occurrence analysis, recognized five clusters using the function of cluster analysis, and explored the knowledge evolution pattern of green building using citation bursts analysis in order to reveal how research related to green building has evolved over time. On the basis of aforementioned keywords, clusters, and citation bursts analysis, this paper has built a knowledge graph for green building. This paper can help readers to better understand the status quo and development trend of green building and to easier recognize the shortcomings in the development of green building, so as to provide a promising direction for future research.

In the Chinese technological tradition, no sector, apart from that of agriculture, is as rich in original ideas as naval architecture. Over the past three millennia, hundreds of different types of craft have been developed for use on China's shallow lakes, on its fast flowing rivers and along its often stormy coastal waters. Each type was developed for specific use as a means of transportation, and would seem to represent the ultimate answer to the challenges posed by local conditions. Ultimate answer, that is, within the limitations of the traditional building materials with which these boats were constructed and fitted out. Nor was ingenuity confined to construction techniques.

When General Aviation (GA) pilots encounter unexpected weather hazards in-flight, the results are typically deadly. It is unsurprising that the National Transportation Safety Board repeatedly lists weather related factors in GA flight operations as an unsolved aviation safety challenge. Solving this problem requires multidisciplinary perspectives. Fortunately, in the past several years innovative laboratory research and industry products have become available. This panel discussion brings together Human Factors and Ergonomics researchers and practitioners to discuss and describe the current work and future directions to avoid weather related accidents in GA.

Since the 18th century, Classification Societies have served the public interest by promoting the security of life, property, and the natural environment. This has been accomplished primarily through the development and verification of standards for the design, construction, and maintenance of marine facilities, however, new insights gained over the past decade have motivated maritime safety organizations to better address the contribution of the human element to maritime casualties and accidents.

Over the past few years the concept of macroergonomics has heightened our awareness of how human factors can be successfully implemented in the work place. One application of this approach addresses the importance of psychological aspects of work that contribute to safe work performance. Traditionally safety interventionists, and to some extent, human factors professionals, have focused exclusively on the physical dimensions of work. Emphasizing the psychological and organizational impacts on safety represents a broader macroergonomic approach to human factors interventions. There is evidence that this approach has merit in reducing human suffering and costs.

The present study was designed to examine the research trends in the literature focusing on Human Factors issues relevant to Unmanned Aerial Vehicle (UAV) systems. As these UAV technologies continue to proliferate with increasing autonomy and supervisory control requirements, it is crucial to evaluate the current and emerging research trends across the generations. This paper reviews the research trends of 228 papers matching our search criteria. The search retained only relevant and complete papers published over the past thirty years (1988-2017) in the Proceedings of the Human Factors and Ergonomics Society. Results were tabulated, graphed, and discussed based on research categories, topic areas, authors’ affiliation, and sources of funding. Results showed a substantial increase in the number of articles in the last two decades, with most papers driven by academic institutions and military and government agencies.

Dam Safety and dam incidents are treated here looked at from the “Human Factors” perspective. An attempt is made to explore these factors as an important drive in impairing dams’ safety and increases their risks. Distinction is drawn between the “Normal Human Caused Incidents” and the “Extraordinary Human Caused Incidents” together with the description of their root origins and subsequent consequences. The first type includes unintentional mistakes, errors and flaws committed by the operators of dams inadvertently, in addition to negligence, lack of experience or overconfidence. Such failings can happen in manual operation of dams, or through the use of their Supervision, Control and Data Acquisition (SCADA) systems as in industrial control system (ICS). They can occur also due to flaws in software or even in the application of information and communication technology (ICT) in remote control operations. As for the second group; the extraordinary human factors, they are defined here as those committed by man with the full understanding of their possible damage. They are done purposely for destabilizing dams after thoughtful and carefully meditated decision making process and they are manifested in acts of war, sabotage and terrorists actions. In this modern age, these acts are characteristics of hackers’ attacks on dam(s) operating systems. This is done through the use of cyberspace by the widespread interconnected digital technology with the accompanying advances in the communication technologies. As such, these technologies have made remote control of such systems possible. Not limited to this, dams remain now, as they were always in the past, the obvious targets in wars and conflicts to inflict losses on the enemy and to use them as weapons, and for terrorism actions for challenging governments. Examples of the aforementioned threats are described with examples given from real cases to elucidate the dangers involved. Lessons to be learned from these incidents are derived and recommendations are presented to be followed to avoid risky situations.
