Innovative alphanumeric data entry and edit procedures are required for input-output devices that, constrained by size and usage considerations, are limited to functionality available with multi-character and limited function keys. Such an interface was developed by the authors for Martin Marietta in support of the US Army Single Channel Anti-jam Man-Portable (SCAMP) Program. Two character entry schemes and three message editing protocols were developed and evaluated using a Macintosh-based, Supercard-configured prototype whose conventions were assessed by twelve subjects in a counter-balanced experimental design. One character entry scheme proved to be statistically superior to the other scheme in terms of time and number of keystrokes required, and was universally favored by subjects. Although there was no clearly superior message editing protocol among the three alternatives, one convention was generally favored over the others in terms of performance and ease of operation.

Among other dangers, soldiers in combat often risk hearing damage. A new source of damage is an increase in crew compartment noise resulting from the addition of armored protection to Highly Mobile Multi-Wheeled Vehicles (HMMWVs, commonly known as “Humvee”). To protect soldiers, the US Army may replace the current Interim Headset (IH) with an Improved Tactical Headset (ITH), which uses noise cancellation technology. However, decision makers are concerned that the ITH may affect perception. In the current study, twenty-one soldiers were tested for accuracy of sound localization in an 8 times 2 mixed experimental design (Speaker Location x Headset Type). Results indicate soldiers wearing either headset experienced the front/back confusion typically found in the literature; but soldiers wearing the ITH localized sound more accurately when the sounds originated from their rear and right rear. These findings may support the ITH as the preferred intervention.

During the occupation in the Second World War, British and American soldiers in the Greater-Reykjavik area replaced Icelandic place names with English ones which were easier for them to pronounce and read, and they also anglicized some Icelandic names. In the article, these names are described and discussed. The British soldiers mostly used names which they knew from districts in England and Scotland. The US soldiers were, on the other hand, more fond of names of heroes and generals in the US army. The English place names never really gained a foothold in Iceland after the Second World War, and they disappeared in one decade.

Input -output analysis is being widely used in developing countries for planning purposes. For a given level of final demand, input-output analysis allows us to project the required level of gross output to ensure consistency of plan. These projections are made on the assumption that the existing production structure is optimal and it implies that an increase in demand will be met through the expansion of domestic output even when it can be satisfied through an increase in imports. On the other hand, according to the semi-input-output method, we do not have to increase the output of international sectors in order to meet the increase in demand because the level and composition of these activities should be determined by comparative- cost considerations. These are the only national sectors in which output must increase in order to avoid shortage. The semi-input -output method has been such a useful and important contribution, yet, regrettably, its influence on the planning models had been rather limited.

Background: Insult to the brain, whether from trauma or other etiologies, can have a devastating effect on an individual. Symptoms can be many and varied, depending on the location and extent of damage. This presentation can be a challenge to the optometrist charged with treating the sequelae of this event as multiple functional components of the visual system can be affected. Case Report: This paper describes the diagnosis and subsequent ophthalmic management of an acquired brain injury in a 22 year old male on active duty in the US Army. After developing acute neurological symptoms, the patient was diagnosed with a pilocytic astrocytoma of the cerebellum. Emergent neurosurgery to treat the neoplasm resulted in iatrogenic cranial nerve palsies and a hemispheric syndrome. Over the next 18 months, he was managed by a series of providers, including a strabismus surgeon, until presenting to our clinic. Lenses, prism, and in-office and out-of-office neurooptometric rehabilitation therapy were utilized to improve his functioning and make progress towards his goals. Conclusions: Pilocytic astrocytomas are the most common primary brain tumors, and the vast majority are benign with excellent surgical prognosis. Although the most common site is the cerebellum, the visual pathway is also frequently affected. If the eye or visual system is affected, optometrists have the ability to drastically improve quality of life with neuro-optometric rehabilitation.

The combine harvest for soybean crops market are currently available two types of combine with header or platform, one of conventional with revolving reel with metal or plastic teeth to cause the cut crop to fall into the auger header and the other called "draper" headers that use a fabric or rubber apron instead of a cross auger, there are few test about performance of this combine header for soybean in Mato Grosso State. The aim of this work was to evaluate the soybean harvesting quantitative losses and performance using two types combine header in four travel speed. The experiment was conducted during soybean crops season 2014/15, the farm Tamboril in the municipality of Pontes e Lacerda, State of Mato Grosso. The was used the experimental design of randomized blocks, evaluating four forward harvesting speeds (4 km h-1, 5 km h-1, 6 km h-1 and 7 km h-1), the natural crops losses were analyzed, loss caused by the combine harvester (combine header, internal mechanisms and total losses) and was also estimated the  field performance of each combine. Data were submitted to analysis of variance by F test and compared of the average by Tukey test at 5% probability. The results show the draper header presents a smaller amount of total loss and in most crop yield when compared with the conventional cross auger.
