With the rapid evolution of communication technology, it became possible to overcome the spatial and temporal limitations faced by humans to some extent. Furthermore, the quality of personal life was revolutionized with the emergence of the personal communication device commonly known as the smart phone. In terms of defense networks, however, due to restrictions from the military and security perspectives, the use of smart phones has been prohibited and controlled in the army; thus, they are not being used for any defense strategy purposes as yet. Despite the current consideration of smart phones for military communication, due to the difficulties of network configuration and the high cost of the necessary communication devices, the main tools of communication between soldiers are limited to the use of flag, voice or hand signals, which are all very primitive. Although these primitive tools can be very effective in certain cases, they cannot overcome temporal and spatial limitations. Likewise, depending on the level of the communication skills of each individual, communication efficiency can vary significantly. As the term of military service continues to be shortened, however, types of communication of varying efficiency depending on the levels of skills of each individual newly added to the military is not desirable at all. To address this problem, it is essential to prepare an intuitive network configuration that facilitates use by soldiers in a short period of time by easily configuring the strategy network at a low cost while maintaining its security. Therefore, in this article, the author proposes a Zigbee-based local strategic network by using Opnet and performs a simulation accordingly.

While China's military rise is an issue of growing importance to regional security, it is worthwhile to note that it is not China's military modernization per se, but its capacity to project and sustain power along and beyond its borders--in particular, the possibility to resolve forcefully its outstanding maritime disputes and various contingencies. This essay argues that China's "anti-access capability"--a U.S.-coined term originally developed for a Taiwan contingency--is equally applicable to other major regional cases such as the Spratly disputes and a North Korean contingency. Furthermore, notwithstanding China's continuos efforts to develop and deploy various types and classes of weapons/platforms, it is the Russian systems and technologies that are most capable and thus likely assigned to the highest mission-critical areas. In assessing China's current and likely future military capability as well as their implications for the region, it is necessary to take note of the following: • There exists asymmetry of military capability between China and its weaker neighbors. While the PLAN is weak in several important aspects, for instance, many of its neighbors' navies are weaker still. • Some have argued that China's foreign policy behavior apparently became more "assertive" in 2009-2013, but it is wiser to keep in mind that China has almost always been assertive and aggressive when it comes to what China defines as "sovereignty and territorial issues" as well as its newest "core interests." • On the South China Sea disputes it is the function of U.S. presence in the theater--in the form of overseas bases and the freedom of navigation--and the PLA's own limitations to project and sustain power for an extended period of time that have largely prevented armed. • While Taiwan remains the idee fixe of China's diplomacy and military, it is and will be a tough nut to crack. China's recent creeping attempts for economic integration with Taiwan should be seen in this context. • China and Japan, the two regional heavyweights and traditional rivals, will likely have a bilateral relationship that is replete with difficulties and tension. China's unilateral announcement of its ADIZ in November 2013 as well as the occasional yet persistent disputes with Japan over the Senkaku/Diaoyudao/Diaoyutai islands are only the latest manifestation of this deeper and difficult relationship. • For Korean security it is imperative to take into account the geostrategic and historical factors. On top of the existing military threats from North Korea, the ROK should be able to employ a) hedging strategy, b) "limited defense sufficiency" strategy, and c) rock-solid relations with the United States.

본 연구는 현실주의의 대표적 이론인 세력균형이론을 기초로 군사력을 국가의 핵심 힘으로 전제하여 동북아시아의 힘의 분포를 살펴본다. 이전 세력균형과 군사력 수준에 관한 연구결과를 고찰하고, 그 연구한 결과를 활용하여 2020년까지 미국, 중국, 러시아, 일본, 한국과 북한의 힘의 변화를 분석하여 2030년경 안보환경을 전망하여 본다. 세력균형이론에서 국가(nation)나 국가군(a group of power) 간에 힘의 균형이 무너지면 전쟁 가능성이 높고, 그 불확실성과 불신이 높은 국제사회에서 생존과 안전을 확보하기 위하여 국가는 힘의 증강(자조, self-help)과 더불어 협력(cooperation)과 동맹(alliance)을 더욱 강화하는 행동을 한다고 본다. 동북아시아의 국가들도 자국의 군사력을 지속 증강하고 있으며, 특히 중국의 급속한 부상으로 국제 안보환경의 급격한 변화에 주변 국가들은 촉각을 세우고 경계심을 늦추지 않고 있다. 중국은 2030년대 중국 창군 100주년과 더불어 '국방 및 군현대화'를 실현하고, 2050년대 건국 100주년에 '세계일류군대건설'을 목표로 하고 있다. 그리고 미국은 국제사회의 협력과 동맹 강화 등 중국 견제에 분주하다. 미국과 중국이 패권경쟁이 진행되고 있는 상황에서 동북아시아의 안보환경과 힘의 역학관계도 서서히 변하고 있다. 세력균형이론에 기초하여 2030년 이후 동북아시아의 힘의 분포 변화와 함의를 살펴보고자 한다.

In this paper, we have proposed a design for security network system passing through the non-security network which is commonly used for various networking services. Based on the security requirements which are assumed that the large classified data are bi-transmitted between a server and several terminals remotely located, some application methods of security techniques are suggested such as the network separation technique, the scale-down application technique of certification management system based on the PKI(Public Key Infrastructure), the double encryption application using the crypto-equipment and the asymmetric keys encryption algorithm, unrecoverable data deleting technique and system access control using USB device. It is expected that the application of this design technique for the security network causes to increase the efficiency of the existing network facilities and reduce the cost for developing and maintaining of new and traditional network security systems.

The limits of current DN(Defense networks), private and closed network, become to reality; for Example, high expense of construction and maintenance of networks, restriction of new subscribers on DN. Therefore, a network using web environment that reflect fast development of If and IS(Information Security) technology is demanded for MND. Meeting the requirement of reliable IS system and extension and improvement of DN using common network, we can reduce the expense to extend, maintain, repair DN, form the environment that makes military business cooperate better with civil company and government agency, advance implementing Defense computing and networking service for field small size units that was a exception of Defense digitalization. But it is essential to construct DN based on common network that there are security requisites; confidentiality, integrity, availability, efficiency, log, backup, restoration, that have to be realized at demanding level for IS. This thesis suggested four measurements; replacement DN with common network to resolve the requirements of building new network and improvement of performance for private DN, linkage with common network for new requirement, distribution of traffic using common network, configuration of DN using Internet and Proposed a refinement of IS management organization to treat security threat of common network flexibly, and LAN IS standard model of DN based on the web environment.

장병들의 무형전력을 구성하는 정신전력은 최근에 우리가 처한 안보상황을 감안할 때 매우 중요하다고 하겠다. 동서고금을 막론하고 전쟁사를 살펴보면 무형전력은 국가의 흥망성쇠는 물론 전쟁의 승패를 좌우하는 핵심적인 요소로 평가되고 있다. 최근 우리 군이 군에서 시행되고 있는 정신교육을 개선하기 위해 나름대로의 노력에도 불구하고 여전히 대다수의 장병들은 정신교육을 '의례적인 교육, 지루한 교육, 시간 때우기 식 교육'으로 여기고 있으며, 불미스러운 군 관련 사건과 사고가 발생할 때마다 정신교육의 효과에 대해 의문과 문제가 끊임없이 지적되고 있는 실정이다. 따라서 본 연구는 바로 이러한 문제의식에서 시작된 것으로서 그 목적은 현행 군 정신교육의 문제점을 분석함으로써 인지중심의 군 정신교육의 발전방향을 모색하여 다변화 시대에 적합한 강군을 양성하는데 방향을 제시하고자 한다.

This article deals with military thought in general. First I tried to distinguish 'thought' from 'theory', 'philosophy', and 'principle'. Thought means the act of thinking about or considering something, an idea or opinion, or a set of ideas about a particular subject, e.g. military affairs in the present discussion. Theory means a formal statement of the rules on which a subject of study is based or of ideas which are suggested to explain a fact or event or, more generally, an opinion or explanation. Philosophy means the use of reason in understanding such things as the nature of reality and existence, the use and limits of knowledge. Principle means a basic idea or rule that explains or controls how something happens or works. Chapter 3 summarized the characteristics of military thoughts into five points', (i) it is closely related with concrete experiences of a nation; (ii) it includes philosophical and logical arguments; (iii) it relies heavily on the political thought of a nation; (iv) it includes necessarily value-judgments; (v) it contains visions of a nation which are not only descriptions or explanations of military affairs, but also evaluations and advocacies. Chapter 4 considers the relation of international political thoughts to military thought. Throughout the history of the modem states system there have been three competing traditions of thought: the Hobbesian or realist tradition, which views international politics as a state of war; the Kantian or universalist tradition, which sees at work in international politics a potential community of mankind; and the Grotian or internationalist tradition, which views international politics as taking place within an international society. Chapter 5 considers the law of war, which is a body of law concerning acceptable justifications to engage in war (jus ad bellum) and the limits to acceptable wartime conduct (jus in bello). Among other issues, modem laws of war address declarations of war, acceptance of surrender and the treatment of prisoners of war, military necessity along with distinction and proportionality, and the prohibition of certain weapons that may cause unnecessary suffering.

우리 군(軍)은 장병의 헌법상 권리와 인권을 실질적으로 보장하고 군 사법개혁에 대한 시대적 요구에 부응하기 위하여 2018년 국방개혁 2.0의 개혁안을 발표하였다. 이와 같은 개혁안을 통해 공정하며 독립적인 군 사법 시스템 구축을 위하여 고등군사법원을 폐지함으로써 군내 온정주의 논란을 근절하고, 평시에 한해 심판관 제도 및 관할관 확인조치권 제도 폐지를 추진함으로써 군 판사의 독립성과 전문성을 제도적으로 보장하여 오로지 법과 양심에 따라 재판할 수 있도록 하였다. 이번 군 사법개혁안은 획기적인 만큼 반대의 목소리도 높지만 더 이상 군대가 민주화의 예외가 될 수 없으며 인권의 사각지대라는 오명에 휩싸이지 않도록 노력하여야 할 것이다.

본 연구는 저출산과 사회 변화로 인해 점점 더 심각해지고 있는 군간부 인력 충원 문제를 분석하고, MZ세대의 특성을 고려한 인력 충원 전략을 모색하고자 한다. 군은 북한의 지속적인 군사적 위협 속에서 안보를 지키기 위해 노력하고 있으나, 저출산으로 인해 병역 자원이 급감하고 있어 인력 충원에 직접적인 영향을 미치고 있다. 또한, MZ세대의 가치관 변화와 군 조직 문화의 괴리로 인해 우수 인재 유치에도 어려움을 겪고 있다. MZ세대는 일과 삶의 균형, 수평적 관계, 자아실현 등을 중시하며, 권위적이고 수직적인 군 조직 문화는 이들에게 매력적으로 다가오지 않는다. 이에 본 연구는 군의 인력 충원 문제점을 진단하고, MZ세대의 특성을 반영한 맞춤형 인력 충원 전략을 제시하여, 미래 군의 지속가능한 발전 방향을 모색하는 것을 목적으로 한다.

With developing computer and communication technologies, the concept of CALS system has been popular not only to military but also to commercial industries. The security problem is one of the most critical issues to construct CALS infrastructure. The CALS system needs some security functions such that data confidentiality, integrity, authenticity, availability, and non-repudiation. This paper proposes a security architecture model in CALS. The security architecture model is composed of 5 submodels such that network security model, authentication and key management model, operation and audit model, integrated database security model, and risk analysis model.
