Military boxing, a kind of Chinese martial arts, is widespread and health beneficial. In this paper, the authors introduce a military boxing learning system realized by 3D motion capture, Web3D and 3D interactive technologies. The interactions with the system are natural and intuitive. Users can observe and learn the details of each action of the military boxing under different views and scales by translating, rotating and zooming the 3D human body models. Smartphones also can be used as the input/output device in the system, which provides natural interactive operations by voice and sensor technologies. The evaluation test has shown that the learning effect of the system is better than via traditional video. The system can be extended to Tai-Chi, gymnastic exercises and other routines.

Unmanned Aerial Vehicle (UAV) networks are an emerging technology, useful not only for the military, but also for public and civil purposes. Their versatility provides advantages in situations where an existing network cannot support all requirements of its users, either because of an exceptionally big number of users, or because of the failure of one or more ground base stations. Networks of UAVs can reinforce these cellular networks where needed, redirecting the traffic to available ground stations. Using machine learning algorithms to predict overloaded traffic areas, we propose a UAV positioning algorithm responsible for determining suitable positions for the UAVs, with the objective of a more balanced redistribution of traffic, to avoid saturated base stations and decrease the number of users without a connection. The tests performed with real data of user connections through base stations show that, in less restrictive network conditions, the algorithm to dynamically place the UAVs performs significantly better than in more restrictive conditions, reducing significantly the number of users without a connection. We also conclude that the accuracy of the prediction is a very important factor, not only in the reduction of users without a connection, but also on the number of UAVs deployed.

President George W. Bush's Iraq surge decision in late 2006 is an interesting case for civil-military relations theory, in particular, the debate between professional supremacists and civilian supremacists over how much to defer to the military on decisions during war. The professional supremacists argue that the primary problem for civil-military relations during war is ensuring the military an adequate voice and keeping civilians from micromanaging and mismanaging matters. Civilian supremacists, in contrast, argue that the primary problem is ensuring that well-informed civilian strategic guidance is authoritatively directing key decisions, even when the military disagrees with that direction. A close reading of the available evidence—both in published accounts and in new, not-for-attribution interviews with the key players—shows that the surge decision vindicates neither camp. If President Bush had followed the professional supremacists, there would have been no surge because his key military commanders were recommending against that option. If Bush had followed the civilian supremacists to the letter, however, there might have been a revolt of the generals, causing the domestic political props under the surge to collapse. Instead, Bush's hybrid approach worked better than either ideal type would have.

In his introductory address at the third International Refresher Course for Junior Medical Officers, Dr. H. Meuli, member of the ICRC, said “No one knows war better than the military medical officer, nor measures its horror, nor hates it more. No one has greater insight into war to enable him to take a stand for peace and against war”. From its very beginnings the Red Cross has been linked to medicine; it was the ICRC which obtained for doctors the means of exercising their profession in war, which are laid down in the Geneva Conventions.It therefore seems appropriate to quote extensively from a communication submitted at the Course by an Italian doctor, bearing moving testimony to the difficulties facing the medical officer, the noble character of his mission and the principles underlying his activity in the prisoner of war camp. These principles were summed up in his conclusion : “Like peace and justice, medicine loses its significance if not accompanied by charity. If it is to stay universal, it must not lose its humanity”. (Ed.).

The survey realized in 1992 on a military population allowed to collect anthropometric data on 688 males and 328 females. Among 73 measurements and 3 index, 26 of them have been retained for the comparison with previous surveys. Generally used for dimensioning human body models these data represent somatic measurements of reference, as weight and stature and segmentary measurements of trunk and limbs. A comparison with previous data, collected on a equivalent military population in 1973, confirms the modifications along the time are so significant that they can be considered as a phenomenon of morphological evolution. Likewise, the modification of the academic levels, average age and socio-cultural structures in the populations are combined to increase the anthropometric variability. It appears the military population presents a morphological modification with an overall increase in weight, stature and correlated dimensions. Otherwise, a light decrease of the cormic index indicates that the morphological transformation influences on the body proportions, with an increase more notable for the lower limbs compared to the trunk. The collected anthropometric information allow to update the Individual Database of ERGODATA from which ergonomie recommendations and statistical and morphological models of the human body can be proposed.

Power sports have always been very popular among servicemen. This is especially evident in recent times, when such power sports, as armsport, crossfit, kettlebell lifting, powerlifting have received some development. The article presents a comparative analysis of the power capabilities of cadets who specialize in various power sports. The study involved male cadets of the 4th year of various faculties (n=53) of the Military Academy (Odessa), who in the process of training were engaged in power sports: armsport (n=12), crossfit (n=16), kettlebell lifting (n=15), powerlifting (n = 10). In addition, the results of cadets-athletes were compared with the results of cadets of the faculty of training specialists of airborne assault troops and military intelligence and special purpose, who did not attend sports sections of the academy (n=60). Analysis of the power of the cadets was carried out on the following exercises: pull-up, lifting by coup, lifting by strength on the crossbar, 24 kg kettlebell snatch, push-up on the parallel bars, push-up. The conducted researches testified to the high level of development of power qualities of cadets of all sections of academy in power sports. There was no significant difference between the results of cadets of different power sports in most exercises. It is established that the power capabilities of cadets who are engaged in various power sports are significantly better than those of cadets who are not engaged in sports. This suggests that any of the studied power sports can be an effective means of developing and improving the power opportunities of future officers of the Armed Forces of Ukraine

Peer-assessment and video comment-sharing are effective learning strategies for students to receive feedback on their learning. Researchers have emphasized the need for well-designed peer involvement in order to improve students' abilities in the cognitive and affective domains. Although student perceptions of peer-assessment have been studied extensively in higher education, few studies have focused on the effects of the peer-assessment strategy on students' performance from the affective perspective, especially in Physical Education courses. Therefore, in this study, a peer-assessment mobile physical education approach is proposed for developing a mobile learning system for a Kung Fu Tai-Chi physical education course. To evaluate the effectiveness of the proposed approach, an experiment was conducted by assigning 42 college students to participate in this learning activity. The experimental results show that the proposed approach not only promoted the students' learning interest and motivation, but also improved their learning self-efficacy and socialization.

Nowadays, due to easiness and expansion in property of smart mobile devices, it is becoming inevitable for mobile applications to have an important role in higher education systems. The Egyptian public universities are facing the problem of students’ large number enrolled in each year. Thus, we lack proper communication between educators and learners. Mobile learning can solve that problem, and it enables adjustment of the curriculum to meet students' learning time and life situations. It provides different solutions better than traditional educational methods. Students and professors could exchange educational material or information even if they are not in the same class. Furthermore, the cost of universities’ materials reduced, as all course materials can be found online through mobile applications. This paper proposes a mobile learning system named “Easy-Edu.” The proposed system intended to make the learning process easier, focus on students’ needs, and encourage communication and collaboration between students and professors and supports collaborative scenario-based learning for university students. Unlike other traditional systems, the proposed “Easy-Edu” was built using an Agile-based approach that delivers sustainable and high-quality mobile learning system. In addition, it eliminates the chances of absolute system failure and detects and fixes issues faster. Summarily, everything related to the design and implementation of “Easy-Edu” is discussed.
