Northeast Asia has a multi-layered security structure within which major economic and military powers both confront one another and cooperate at the same time. Major regional powers maintain mutually cooperative activities in the economic sphere while competing one another in order to secure a dominant position in the politico-military arena. The multifarious threats, posed by the North Korea's nuclear development, territorial disputes, and maritime demarcation line issues demonstrate that Northeast Asia suffers more from military conflicts and strifes than any other region in the world. Specifically, major maritime security threats include North Korea's nuclear proliferation and missile launching problems as well as military provocations nearby the Northern Limit Line(NLL) as witnessed in the Cheonan naval ship and Yeonpyong incidents. The ROK Navy has been supplementing its firm military readiness posture in consideration of North Korea's threats on the NLL. It has performed superb roles in defending the nation and establishing the Navy advanced and best picked. It also has been conducive to defend the nation from external military threats and invasion, secure the sea lanes of communications, and establish regional stability and world peace. In order to effectively cope with the strategic environment and future warfares, the ROK Navy needs to shift its military structure to one that is more information and technology intensive. In addition, it should consolidate the ROK-US alliance and extend military cooperative measures with neighboring countries in the Asia-Pacific region. Evolved steadily for the last 60 years, the ROK-US alliance format has contributed to peace and security on the Korean peninsula and in the Northeast Asian region. In conclusion, this manuscript contends that the ROK Navy should strive for the establishment of the following: (1) Construction of Jeju Naval Base; (2) Strategic Navy Equipped with War Deterrence Capabilities; (3) Korean-type of System of Systems; (4) Structure, Budget and Human Resources of the Naval Forces Similar to the Advanced Countries; and (5) Strategic Maritime Alliance and Alignment System as well as Domestic Governance Network for the Naval Families.

In The Turn of the Screw, the go'erness encounters with the apparitions that harrow her throughout the story: she sees a frightening male ghost that Mrs. Grose identifies as Peter Quint, deceased former 'alet of the children's uncle, who had pre'iously shared the charge of the children with the pre'ious go'erness, Miss Jessel. The appearance of the ghosts hails the go'erness and thereby forces her to be jarred out of the comfortable habits of indi'iduality and plunged into a negati'ity de'oid of the socio-normati'e directi'es and guarantees. Such an encounter shows the idea that consciousness is a plenum of existence e'ocati'e of human mind as a decentered pandemonium. For the go'erness in The Turn of the Screw, the foundation to force her to experience the uncanny, as an inconsistency in the symbolic order, is particular. Its particularity is absolute in the same way e'ery one of us dreams his or her world. It resists mediation and cannot be made part of a symbolic medium. Just as Lacan's conceptions of desire, feminine sexuality, 'Object a,' not-whole, sla'ery, mastery, self-deception, authenticity, and act of psychoanalysis help us understand our contradictory social reality, so does The Turn of the Screw help us make sense of the way the go'erness, as the being who is capable of raising the question of being, questions the idea of being. In conclusion, the particular way the go'erness dreams her world is e'ocati'e of an excessi'e being, an anatomical complement, and a particular experience, such as the go'erness's encounter with the ghosts testifies to a knowledge that escapes the knowledge of the speaking being.

Recently, the Japanese government revised the three guidelines of its security policy, the National Security Strategy(NSS), the National Defense Program Outline and Midterm Defense Buildup Plan, exceptionally at one time. This means Japan has been seeking the new strategy and strengthening military power considering changing regional security environment. Moreover, Japan revised the security laws for the right to collective self-defense, which authorized the use of force even when Japan is not under attack. Also, Japan renewed the Guidelines for Japan-U.S. Defense Cooperation in twenty years, and has expanded JSDF's scope of activity to a worldwide level. These changes imply Japan would constantly seek to build military forces focusing on naval forces. Because Japan's naval forces, the JMSDF is the means that allow Japan to use its force at anywhere overseas and expand its roles and missions in international society by the basis of the right to collective self-defense. This research will analyze Japan's new maritime strategy and trend of force development and eventually look for the implication on our maritime security These days, Japan has perceived Chinese rapid increase of naval power and pursuing of maritime hegemony as a grave threat. In response to this, Japan is designing new maritime strategy, which are "remote islands defense and recapture" and proactively develop a new type of naval forces to accomplish this new strategy. The Japan's "remote island defense and recapture strategy" is to harden its defensive posture in Nansei islands which correspond to China's 1st island chain for chinese A2/AD strategy and directly encounter with China and to protect its own dominium and maritime interest while supporting US national strategy in East Asia. Japan continues to build compact, multi-functional ship to accomplish "remote island defense and recapture strategy" and keep strengthening its maritime power projection capability to include build of new amphibious ship, and large, multi-functional ship which can provide effective C2. These changes imply that Japan is shifting its strategy from passive and defensive to proactive and aggressive way and continues to pursue naval buildup.The implication of Japan's new maritime strategy and naval buildup needs to be observed carefully and we need to keep developing naval power required to protect our maritime sovereignty and interest.

After finishing Cold War, the U.S. Navy's ability to Sea control has been gradually eroded last 15-20 years. The global security environment demands that the surface Navy rededicate itself to sea control, as a new group of potential adversaries is working to deny U.S. navy command of the sea. China has been increasing their sea denial capability, such as extended anti-surface cruise missile and anti-surface ballistic missile. To cope with this situation, the U.S. Naval Surface Forces Command has announced Surface Forces Strategy: Return to Sea Control. It is a new operating and organizing concept for the U.S. surface fleet called 'distributed lethality'. Under distributed lethality, offensive weapons such as new ASCMs are to be distributed more widely across all types of Navy surface ships, and new operational concept for Navy surface fleet's capability for attacking enemy ships and make it less possible for an enemy to cripple the U.S. fleet by concentrating its attack on a few very high-value Navy surface ships. By increasing the lethality of the surface ships and distributing them across wide areas, the Navy forces potential adversaries to not only consider the threat from our carrier-based aircraft and submarines, but they now consider the threat form all of those surface ships. This idea of using the distributed lethality template to generate surface action groups and adaptive force package and to start thinking about to increase the lethal efficacy of these ships. The U.S. Navy believes distributed lethality increases the Navy's sea control capability and expands U.S. conventional deterrence. Funding new weapons and renovated operating concept to field a more lethal and distributed force will enable us to establish sea control, even in contested area. The U.S. Navy's Surface Forces Strategy provides some useful implications for The ROK Navy. First the ROK Navy need to reconsider sea control mission. securing sea control and exploiting sea control are in a close connection. However, recently the ROK Navy only focuses on exploiting sea control, for instance land attack mission. the ROK Navy is required to reinvigorate sea control mission, such as anti-surface warfare and anti-air warfare. Second, the ROK Navy must seek the way to improve its warfighting capability. It can be achieved by developing high-edge weapons and designing renewed operating concept and embraced new weapon's extended capabilities.

Field trials evaluating selected commercially available mosquito traps variously baited with light, carbon dioxide, and/or octenol were conducted from 18-27 September 2000 in a malarious area near Paekyeon-ri (Tongil-Chon) and Camp Greaves in Paju County, Kyonggi Province, Republic of Korea. The host-seeking activity for common mosquito species, including the primary vector of Japanese encephalitis, Culex tritaeniorhynchus Giles. was determined using hourly aspirator collections from a human and propane lantern-baited Shannon trap doting hours when temperatures exceeded $15^{\circ}C$. The total number of mosquitoes and number of each species captured during the test was compared using a block design. Significant differences were observed for the total number of mosquitoes collected, such that, the Mosquito MagnetTM with octenol > Shannon trap > ABC light trap with light and dry ice > Miniature Black Light trap (manufactured by John W. Hock) $\geq$ New Jersey Trap > ABC light trap with light only. Significant differences in numbers collected among trapes were noted for several species including: Aedes vexans (Meigen), Anopheles lesteri Baisas and Hu. An. sinensis Weidemann, An. sineroides Yamada, An. yatsushiroensis Miyazaki. Culex pipiens pallets Coquillett L., Cx. orientalis Edwards and Cx. tritaeniorhynchus. Host-seeking activity for most common species showed a similar bimodal pattern. Results from these field trap evaluations can significantly enhance current vector and disease surveillance efforts especially for the primary vector of Japanese encephalitis, Cx. tritaeniorhunchus.

이 논문은 "주역"의 십익(十翼) 중 하나인 "서괘전"의 내용이 곧 교육의 과정을 뜻함을 논한다. 특히 건괘(乾卦)에서 11번째 괘인 태괘(泰卦)에 이르는 "서괘전"의 내용은 사람이 태어나서 스스로 공부할 수 있는 최소한 여력을 갖추는 일련의 과정을 정확하게 설명하고 있다. 이 내용을 기존 교육학에서 소개된 교육의 과정 틀 속에서 분석하고 논의한다. 교육목적이 어떻게 진술된다고 하더라도 그것은 교육받는 아동의 이익을 도모해야 한다. 그러나 이러한 취지는 서양의 소위 아동중심교육, 진보교육 사상에 의하여 크게 왜곡되었다. 한 마디로 '교육'이 아닌 '아육(兒育)'이 되어버린 것이다. 이 논문에서 분석한 "서괘전" 내용은 이러한 왜곡을 시정할 수 있는 가장 강력한 논거를 제공한다. "서괘전"은 이 점에서 실추되어 가는 교권 문제 회복을 위한 논거도 제공한다. 또한 소축괘(小畜卦)와 이괘(履卦)는 교육재정 분배와 복지문제에 시사하는 바가 매우 크다. 끝으로 "서괘전"이 현행 교육체제와 운영이 효용위주로 흐르는 것을 경계하고 교육의 본질을 생각하게 한다는 점에서 "서괘전"은 우리가 받들어 공부해야 할 경전임을 일깨워준다.

In this article we consider the class ${\mathcal{A}}(p)$ which consists of functions that are meromorphic in the unit disc $\mathbb{D}$ having a simple pole at $z=p{\in}(0,1)$ with the normalization $f(0)=0=f^{\prime}(0)-1$. First we prove some sufficient conditions for univalence of such functions in $\mathbb{D}$. One of these conditions enable us to consider the class ${\mathcal{A}}_p({\lambda})$ that consists of functions satisfying certain differential inequality which forces univalence of such functions. Next we establish that ${\mathcal{U}}_p({\lambda}){\subsetneq}{\mathcal{A}}_p({\lambda})$, where ${\mathcal{U}}_p({\lambda})$ was introduced and studied in [2]. Finally, we discuss some coefficient problems for ${\mathcal{A}}_p({\lambda})$ and end the article with a coefficient conjecture.

In this paper, vibration and flow-induced flutter instability analysis of cantilever multi-wall carbon nanotubes conveying fluid and modelled as a thin-walled beam is investigated. Non-classical effects of transverse shear and rotary inertia and van der Waals forces between two walls are incorporated in this study. The governing equations and the associated boundary conditions are derived through Hamilton's principle. Numerical analysis is performed by using extend Galerkin method which enables us to obtain more exact solutions compared with conventional Galerkin method. Cantilevered carbon nanotubes are damped with decaying amplitude for flow velocity below a certain critical value, however, beyond this critical flow velocity, flutter instability may occur. Variations of critical flow velocity with both radius ratio and length of carbon nanotubes are investigated and pertinent conclusion is outlined.

The importance of souvenirs are increasing immensely these days owing to the increase of foreign visitors to our country, which forces us to turn our eyes to this field. Upon these reflections, this study aims at aims at developing cap designs that satisfy the foreign tourists needs and let them recognize the outstanding beauty of Korean traditional patterns by applying traditional motifs. The Korean traditional patterns and their symbolic meanings were researched as well as the previous studies on the designing of goods for foreign visitors which had traditional patterns applied. Furthermore, the overall tendencies of the purchase of souvenirs and goods by foreign tourists in Korea as well as in foreign countries were investigated. Next, the present state of apparel goods and caps for sightseers in Korea was analyzed according to their shapes, colors, and patterns. Finally, by using CAD system, new cap designs were developed applying traditional bat motifs in order to capture the traditional images for a modern sense of beauty.

This paper reports a new test facility to investigate the characteristics of the thrusters mounted on the small scale underwater vehicle using Force/Torque sensor. With the test facility proposed here, No disassembly needs be made to the target vehicle, which makes us possible to get the realistic forces of the vehicle rather than the fortes of the thrusters themselves. Experimental data analyses, heave, sway, and surge, for the QI ROV are given as an example of this method.
