The style of war in the $21^{st}$ century became digitalized cooperative union tactic, which relies heavily on the system providing real time information. Critical information is provided during the war from sensing to shooting. Therefore, epochal development in observation, reconnaissance (ISR), commanding (C4I) and precision strike (PGM) are necessary. Application of ubiquitous computing and network technologies in national defense is necessary for carrying out with various types of wars in the $21^{st}$ century. Therefore, the author wants to research core technology sector that can be developed and applied in preparation of ubiquitous national defense era. Also plans for applying recent u-Defense technology to the military sector had been suggested. Particularly, the author have suggested plans for utilizing combined future information technologies such as ad-hoc network, RFID for the logistic supply in construction of u-Defense system. By utilizing these information technologies, combat power and strategic capabilities of the military can be enhanced greatly.

The purpose of this study was to find out the influence of the Parent's control based on young children's habit of lying. This study was carried out through experimental observations. For the purpose of this study a total of 798 participants were selected from 5 kindergartens located in Seoul, Gyeong-gi and Incheon. The results of the study showed that rather than parents being excessively strict towards their children and commanding discipline, the child rearing attitude of rational and logical explanation along with discretionary power given to young children of their own rules. This can allow young children to morally decide and behave themselves. Moreover, moral education that is suited for the young children's development in order to internally learn about the moral behaviors on their own is needed.

In this paper, we present some results on performance analysis for flap actuation system of aircraft. For this, by utilizing MATLAB/Simulink solution, which is widely used physical model-based design tool, we particularly construct the architecture of the analysis model consisting of the main three phases: 1)commanding and outer-controlling the flap angle through flight control computer; 2)generating hydraulic/mechanical power through control module and power drive unit; 3)transmitting torque and actuating the flap through torque tube and rotary geared actuators. For mimicking the motion of the actual flap, we apply each mechanical component, which is already being used in actual aircraft, to our performance analysis model so that it guarantees the congruency of the simulation results. That is, we reflect the actual specifications of flap hardware and software as parameters of the model. Finally, simulation results are presented to illustrate the model.

The tensions between the U.S and China, which form the two pillars of the G2 era, seem to have persisted even after the Trump administration inaugurated. The strong confrontation between the two in recent foreign security issues may drive to develop an inadvertent military conflict, and it is high likely to occur in the maritime are. The purpose of this study is not only to analyze the balance of modernized naval forces in the PLAN through naval strategy changes and weapons system modernization trend, but also to predict the impact of the geographical proximity difference on the balance of naval forces in the disputed areas. It examined the impact of distance and geography on naval power by assessing the modernization pattern of the PLAN and capabilities in the context of two scenarios at different distances from China by 2020: one centered on Taiwan and the other on the Spratly Islands. The PLAN's strategy had impact on operational concept and forces construction. First, from the viewpoint of operation operational concept, it can be seen that the passive defense is changing into active defense. Second, in terms of power construction, it can threaten the surface and submarines of U.S power from a distance. And they generated follow three features; The ocean is not the focus of Chinese submarines, Horizontal and vertical expansion of Chinese naval vessels, The improvement of the suppression ability as the Chinese naval modernization ratio increases. The strength of the PLAN is dominant over the U.S in terms of reserves, and it can complement the qualitative deterioration by utilizing nearby bases in the vicinity of the mainland, such as the Taiwan Strait. However, due to the shortage of aircraft carriers, there is a possibility that it will take some time to secure the advantage of air and ocean in the amphibious operation. Therefore, as the dispute is prolonged, China may fail to achieve its original goal. In addition, the lack of cutting edge Commanding Ships may bring to weaken the C2 capabilities. At results, it is expected that PLAN will not be able to have a superiority in the short term due to lagging behind U.S advanced technology. Nevertheless, PLAN has strengthened its naval power through modernization sufficiently and it is highly likely to use force. Especially, it is more likely in the region where the naval power operation like the Taiwan Strait is possible with the almost equality to that of the United States. China will continue to use its naval forces to achieve a rapid and decisive victory over U.S in the close area from the land.

화약(흑색화약)의 최초로 발명된 사실은 초석 의 제법 및 그 정제법과 밀접한 관계가 있다. 중국인들은 이미 11세기초부터 초석의 제법을 알고 있었으며, 그들이야말로 화약원료인 초석의 제법을 세계에서 가장 최초로 발명해 낸 사람들이다. 에지프트인들은 그것을 중국의 눈이라고 불럿으며, 초석이 유럽에 전파된 시기는 성길은오이 1218년 서정작업중 패르시아의 성첩를 공격하기 위하여 화약을 사용한데서부터 시작된 것으로 생각된다. 한국에 화약 및 초석의 제조기술이 중국으로부터 도입된 시기는 1374년이며 화약을 최초로 한국에서 만들어낸 사람은 최무선이였다. 이조시대에 접어 들면서 초석, 화약 및 화포의 제조기술은 최해신에 의해서 매우 발전해 나갔다. 그러나 1597년 일본의 왜군이 한국을 침공해 왔을때(임진란) 왜군은 성능좋은 조총으로 한국군을 괴롭혔으며 이에 맞서서 이순신장군이 이끄는 한국의 수군은 거북선에 장비한 성능좋은 화포로서 일본수군을 전멸시킬 수 있었다. 한국의 근대화약기술은 1930년부터 1945년 사이에 4개의 화약공장이 건설됨으로서 매우 발전했다. 본 연구는 한국에 화약기술이 전래된 경위를 조사하였으며 차후화약기술에 대해서 연구하고져 하는 연구자에게 연구 자료를 제공 하고져 시도했다.

Orientalness is a concept that expresses the collective identity of the Orient in relation to the West. The concept itself is mutable and defined by the relationship between the two regions at different points in time. Changes in the concept depend on a number of factors, such as cultural influence, the political balance of power between the two regions, and on the interpretative scheme that defines the relationship. In addition, the geographical notion of the concept evolves culturally, socially and politically. During this process, Oriental-ness becomes Oriental-ism at times. I will attempt to survey and measure the progression of Orientalness from its emergence in early 17th century to its subsequent transformation in modern Korea as reflected in art theory and art works. The recognition of the comparative characteristics of Oriental art began when the Orient was exposed to the art of the West in the late Ming dynasty during the early 17th century. The changes in the artistic climate in China affected the late Chosun. I will start with a brief introduction of this time and the birth of Orientalness. The concept gradually changed during the period of Enlightenment(開化期) towards the end of the 19th century, and during the colonial period( 1910-1945) it took on a new form. Establishment of the concept of "Orient"as a single, unifying concept spanning across cultures and national boundaries has been attributed to late Meiji period Japan, whose intention at that time is believed to have been to build a pan-Asia(亞細亞) empire with Japan at its commanding center. It has been stressed that the real motive behind the formation of one single cultural unit, where the shared common written language was Chinese and Confucianism and Taoism were the common metaphysical traditions, was to build one political unit. When the notion of a geographical unit of Asia was replaced by the concept of Asia as a cultural and political unit, a massive growth of interest and discourse were provoked around the concept of Orientalism. When Orientalism was being formulated, Korea automatically became member of "one Asia" when the country became colonized. For Koreans, the identity of the Orient had to be defined in cultural terms, as the political notion of a nation was non-existent at that time. The definition of identity was pursued at two levels, pan-Asian and local. If Orientalism was an elite discourse centered in pan-Asian philosophical and religious tradition, localized Orientalism was a popular discourse emphasizing locality as the byproduct of natural geographic condition. After the liberation in 1945 from colonial rule, a thrust of movement arose towards political nationalism. Two types of discourses on Orientalism, elite and popular, continued as central themes in art. Despite the effort to redefine the national identity by eradicating the cultural language of the colonial past, the past was enduring well into the present time. As discussed above, even when the painting themes were selected from Korean history, the tradition of using history painting as a manifestation of political policy to glorify the local identity had its founding during the Meiji period. The elevation of folk art to the level of high art also goes back to the colonial promotion of local color and local sentiment. Again, the succession of the past (colonial) ideal was defended as the tradition assumed a distinct modern shape that was abstract in style. The concept of the "Orient" is of relative and changing nature. It was formulated in relation to Western culture or civilization. Whatever the real motive of the adoption of them had been, the superiority of the Orient was emphasized at all times. The essence of the Orient was always perceived as the metaphysical tradition as a way to downgrade Western culture as materialistic. This view still prevails and the principle of Orient was always sought in Confucianism, Taoism, and Buddhism. Even when Orientalism was employed by imperialist Japan in an effort to establish her position as the center of the Orient, the spiritual source was still in Chinese philosophy and religion. In art also, the Chinese literati tradition became the major platform for elite discourse. Orientalism was also defined locally, and the so-called local color was pursued in terms of theme and style. Thus trend continued despite the effort to eradicate the remnants of colonial culture long after liberation. These efforts are now being supported politically and also institutionalized to become the aesthetic ideal of the modern Korean art.

본 연구의 목적은 초등 영재학생과 일반학생의 정의적 특성 중 현대적 효 개념의 행동요인을 비교 분석하여 초등 영재학생과 일반학생의 효 행동 요인에서 어떤 차이가 있는가를 분석하는 데에 목적을 두고, 학년별 출생 순위별 가족 구성 가정교육 종교의 유무에 의한 변인 분석을 통하여 우리나라 영재 교육의 방향성을 모색하고자 하는 것이다. 이에 연구 결과를 요약하면, 첫째, 초등영재학생이 일반학생보다 효 행동에 대한의식이 높게 나타났다. 이는 영재의 지적 정의적 발달과정이 일반보다 빠르게 나타나고 가치준거와 도덕적 문제에 관심이 많기 때문으로 볼 수 있다. 또한 일반학생 내에서 여학생의 효 행동에 대한 의식이 남학생보다 높게 나타났다. 이는 여학생의 정서적 발달이 남학생보다 빠르기 때문으로 볼 수 있다. 둘째, 학년별로 영재학생 내에서 5학년이 6학년보다 효행동에 대한 의식이 높게 나타났다. 이는 학년이 낮을수록 효 행동에 대한 의식이 높게 나타난 것으로 어릴 때부터의 지속적인 교육이 필요하다고 볼 수 있다. 셋째, 가족 구성에서 핵가족을 이룬 집단이 확대가족을 이룬 집단보다 평균간이 다소 높게 나타났다. 이는 핵가족화로의 가족 구성이 변화하고 있음에도 불구하고 가정을 이루는 전통 윤리인 효 행동에 대한 의식을 꾸준히 생활화하기 때문으로 볼 수 있다. 또한 종교의 유무에서도 종교가 있는 집단이 종교가 있는 집단보다 평균같이 다소 높게 나타났다. 이는 종교가 강조하는 사랑 자애 등의 종교적 특성 이 표 행동에 대한 의식을 강화시킨다고 볼 수 있다. 이 연구 결과를 통하여 초등 영재학생이 정의적 특성 중 우리나라의 전통윤리인 효 행동에 대한 의식이 높음을 알 수 있었으며, 이러한 의식이 초등학교에서만 높은 것이 아니라 상급학교에서도 높은 의식을 유지할 수 있도록 지속적인 관심을 갖고 노력할 필요가 있다고 본다.
