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.

This study examines the distribution of power in Northeast Asia based on the balance of power theory, a representative theory of realism, assuming military capabilities as the core power of states. The results of previous studies on the balance of power and military forces are reviewed and used to analyze changes in the strength of the US, China, Russia, Japan, South Korea, and North Korea through 2020 to predict the security environment in 2030. In the balance of power theory, if the balance of power between a nation or a group of powers collapses, the possibility of war is high, and to survive in the international community with high uncertainty and distrust, the theory predicts that states must increase their powers in a self-help world and strengthen cooperation and alliance. Countries in Northeast Asia are also continuing to strengthen their military capabilities, and countries neighboring China are paying keen attention and remaining vigilant due to the rapid changes in the international security environment after the rapid rise of China. To mark the future 100th anniversary of the Chinese armed forces in the 2030s, China aims to realize 'defense and military modernization' and build a 'world-class military force' by the nation's 100th anniversary in the 2050s. The US is busy checking China's rise by strengthening international cooperation and alliances. The security environment and power dynamics in Northeast Asia are slowly changing as the US and China continue to compete for global hegemony. The changes and implications of the distribution of power in Northeast Asia after 2030 are examined based on the balance of power theory.

Recently, weapon system requires personal protection products due to the explosion of rapid-fire explosion, which is considered to be multi threat in modernization, complication and war against terrorism. However, the conventional Korean military bullet protection helmets are not suitable for wearing convenience and combatant interoperability in terms of ergonomic. In this paper, we propose a suitable 3D Scanning method for the head, and compare the measured 3D dimension with the existing 2D measurement value to identity the reliability. Reverse engineered soldier head using the quick surface method was realized with a perfect free-form surface and satisfactory tolerance range (${\pm}0.2mm$). Through the comparison of 3D and 2D measured head dimensions, the absolute error value was 0.73 mm on average and relative error was 0.35 %, confirming the high accuracy of the 3D scan modeling. Also, quick surface method using 3D scanner is suggested a fast and accurate skill for ergonomics in obtaining the head modeling needed for military's personal bullet protection helmet design.

Since 1975, Korean defence quality system has been operated by adopting defence specifications, 0050-0015, 0050-0029 and 0050-0030, which were based on the American specifications, MIL-Q-9858, MIL-Q-45208 and MIL-STD-45662. The trend that the ISO certification is intensively required for the international trade, and the need for modernization of the Korean military forces, however, provide motivation to revise the defence quality system. In this study, an improved defence quality system has been proposed by the comparison study among the requirements prescribed in ISO 9000, AQAP 100 series, MIL-Q-9858.

This paper focuses on analyzing the modern warfare and weapon systems supported by improved GPS informations. The GPS capability was investigated through the real experimental test for verifying the most recent GPS features under its modernization processing. And then it was verified that such capabilities, accuracy and availability, of a typical L1, C/A code GPS receiver are equivalent to the military receiver's ones. It was also sure that the influence of GPS improved informations on NCW(Network-Centric Warfare), PGM(Precision Guided Munition) and C4SIR(Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance) should be increased and the modern warfare may be strongly dependent on GNSS informations.

With the barracks modernization project, the Ministry of National Defense has been operating 60 projects of the 75 that have been announced. It was difficult to investigate and analyze the data in the past because data could not be obtained while it was much easier to do that since data can be obtained from private companies. With the aim of increasing the usability of the facilities, the objective of this study is to present a reasonable alternative for repair and maintenance costs by investigating and analyzing the budget and the actual expenses of repair and maintenance of military facilities for the past 3 to 5 years, and then identifying the problems with these. To accomplish this, a theoretical review of previous studies and legal grounds related to repair and maintenance costs was performed, and data on the estimates and the actual expenses data used in BTL projects carried out by private companies were analyzed. First, one of the problems was that there are some items omitted, including consumables, and these items should be included in order to secure their budget. Second, in terms of the items for divided payments, two improvements had been presented: a short-term payment plan for the operation period of 3 to 5 years and a long-term payment plan for an additional and complemented period other than the operation period. The repair and maintenance costs should be further studied at the point of time in a future when the actual data on the costs and operation period of military facilities can be secured. This study is expected to serve as empirical data that will form the basis for a reasonable calculation of the construction cost for military facilities.

The number of military facilities has been rapidly increased due to growing requirement of modernization and military welfare. However, adequate maintenance has not implemented to these facilities. As a result, they are deteriorated quickly and require performance enhancement treatments. There are two ways of performance enhancement, reconstruction and remodeling. Despite the research result that remodeling within the standard remodeling range is more economical, remodeling of military facilities is not considered equivalent to reconstruction as an option of performance improvement. Therefore, derived from the relationship between performance change during life cycle of building and range of remodeling needs, this study tries to propose Remodeling Process Model(RPM) which uses a method to choose remodeling in a Specific Point of Time(SPT) when remodeling is considered more economical than reconstruction. In addition, this study suggests practical service life and functionality evaluation standard together which require to realize the RPM. This RPM make it possible to avoid the cases that facilities which do not have any problem on structural reliability but have low level of functionality miss appropriate remodeling timing and inevitably choose reconstruction as a performance improvement option. It also present the possibility of simple reconstruction / remodeling decision-making for facility managers who administrate building having various type, compilation and elapsed time. Consequently, this process model focusing on remodeling more may contribute to reduce resource waste caused by reconstruction.

Owing to the complexity and modernization of weapon systems, the role of the defense industry in producing military supplies has become increasingly important. In previous defense industries, price competitiveness was a key factor in the product choice. On the other hand, as exports of domestic military supplies are expanding rapidly based on superior quality, there is a need to evaluate objectively the efficiency of management in the domestic defense industry. In this study, the efficiency of management was measured using DEA, which is one of the decision methodologies. In addition, the number of employees (QA Employee) and R&D performance were set as input variables to utilize DEA, and the output variables were based on sales and operating profit. Based on the results of the analysis, a future study will measure the efficiency of the management of domestic defense industry to help guide a strategic development plan.

This paper is to analyze the trend and implications of the publication of China's defense and security white papers. To this end the paper is composed of 5 chapters titled instruction; publication details and composition of China's defense and security white paper; the gist of the white paper on national defense and security during the Chinese president Xi Jinping era; the implications of Chinese white paper on national defense and security during the Chinese president Xi Jinping era; and conclusion. The Chinese Ministry of National Defense had published seven books every two years since 1998 to 2010. In 1995, the ministry published a white paper titled 'China's arms control and disarmament' for the first time. In 2013, it published a white paper titled 'The Diversified Employment of China's Armed Forces' and 'China's Military Strategy' in 2015. All have the common characteristic of being a propaganda policy reflecting China's strategic calculations. It seems that China has began to publish defense white papers in a proactive manner, due to the following factors: (1)pressure on China to demand military transparency from neighboring countries such as the United States; (2)the erosion of the 'China threat.' and (3)confidence in the achievement of China's military modernization. The 'active defensive strategy' and the 'strong defense strategy' of Si Jinping are implied in the words "China's dream is a dream of a powerful country and dream of a strong nation is essential to construct a strong nation." His these strategies have raised security concerns for neighboring countries. We need to maintain and reinforce strong ROK-US security cooperation, and hedging strategies to harmoniously promote ROK-China economic cooperation.
