Analysis of the Military and Non-military Effects of ROK Navy’s Light Aircraft Carrier

Explosion Bulge Test in air has been carried out in order to evaluate base metal and weldment of pre-heating free steel, PFS-700 which was developed for using in submarine, destroyer and aircraft carrier and specified as Korean military specification, KDS-9515-3001. PFS-700 steel has good weldability so that it can be welded without pre-heating before welding. 1.4wt.% of Copper is added to compensate for the decrease of strength due to the decrease of Carbon in PFS-700. Usually, PFS-700 is aged at the temperature of about 650°C for the combination of strength and toughness. PFS-700 of the thickness of 25mm aged at 650°C was used for explosion bulge test. Underwater weapon system demands to conduct this test for the security of weld structures, and test method and procedure are specified in the military specification, MIL-STD-4139(SH). PFS-700 was explosion bulge tested as specified in this spec. Mechanical tests such as tensile test, CVN impact test, dynamic tear test and bend test are conducted from the specimens taken from prolonged EBT specimen and compared with the properties specified in KDS-9515-3001. EBT results show that PFS-700 welded with the welding material of spoorlarc-120 has over the thickness reduction of 14% without propagation of crack to the hole-down area.

This paper describes a recent Phase I effort to identify methods that could be used to help better define, for designers and engineers, the role of the human in complex system design. This methodology is referred to as Cognitive Function Modeling (CFM). The effort was driven largely by the need to “reduce manning” on complex systems being designed for the military such as the Navy's next generation aircraft carrier (CVX) and cruiser (SC-21). The methodology presented here combines two existing tools, the Operator Function Model and Cognitive Task Analysis, and introduces a new technique to aid the designers and engineers in identifying the components of the new systems that have varying degrees of “cognitive complexity.” By combining these techniques, the overall operator functions and tasks can be identified, they can be examined for cognitive complexity, and then, where needed, detailed cognitive task analyses can be applied. The goal of CFM is to provide the engineers and designers with four products: an overview of all of the tasks and functions associated with the operators; a clear indication of which of these tasks/functions are cognitively complex; a detailed cognitive analysis of these cognitively complex tasks/functions; and recommendations and cautions regarding designing for these specific tasks and functions. CFM provides the engineers and designers an overview of the areas where the roles and functions of the humans and computers need to be examined closely. It also highlights and describes the critical decisions, judgments, cues, challenges, and difficulties associated with these cognitively complex areas so the designers can better understand what their designs must address. Areas for future work are also briefly described.

Digital Replantation

Introduction: Noncombat-related hand injuries are common in current theatres of operations. Crushing is one of the most frequent mechanisms that may cause traumatic amputations of digits. In the military setting, management of these digital amputations is challenging regarding limitation in microsurgical means in medical treatment facilities and aeromedical evacuation delays out of the combat zone. Methods: Two cases of digital replantation performed in French forward surgical units are described. The first case was a complete distal amputation of the medius which was successfully replanted in the operating theatre of an aircraft carrier. No complication was observed after evacuation. Functional and aesthetic results were excellent. The second case was a ring finger avulsion revascularized in a role 2 facility in Central African Republic. Unfortunately, revascularization failed due to arterial thrombosis during evacuation. Results: Digital, hand or more proximal upper extremity replantation may be considered for isolated amputations due to work-related accidents within the combat zone. For a surgeon trained to microsurgery, a microsurgical set and magnification loupes enable to attempt such procedures in austere conditions. Discussion: The authors propose an algorithm of management in the field according to the type and level of amputation.

In many respects, the least important part of the 1999 elections were the elections themselves. From the beginning of General Abdusalam Abubakar’s transition program in mid-1998, most Nigerians who were not part of the wealthy “political class” of elites—which is to say, most Nigerians— adopted their usual politically savvy perspective of siddon look (sit and look). They waited with cautious optimism to see what sort of new arrangement the military would allow the civilian politicians to struggle over, and what in turn the civilians would offer the public. No one had any illusions that anything but high-stakes bargaining within the military and the political class would determine the structures of power in the civilian government. Elections would influence this process to the extent that the crowd influences a soccer match.
