The study aims to evaluate the complexity of relationships between the riparian states - China, Myanmar, Laos, Thailand, Vietnam and Cambodia - in the Mekong River Basin since the mid-1990s with special reference to the discourse on hydropower development. A special emphasis will be put on the influence of China on hydropower development. Although a variety of issues on the river basin have been discussed among the riparian states, none of them has been effectively implemented owing to the lack of China's commitment to the discussions for sustainable water management. Now, a new turning point is observed in the region with emergence of the issue on hydropower development, not only in the upper basin but also in the lower basin. The discourse on hydropower in Mekong has quickly drawn attention of the public, accelerated by the onset of construction of the Xayabury Dam in Laos since November 2010. The influence of China as the upstream country with its political, economic, and military power has increasingly grown in the region over the last few decades, and such trend recently intensifies together with an expansion of Chinese commercial interests in the region. Since the establishment of the Mekong River Commission (MRC) in 1995, the four MRC members have striven to push forward a sustainable use of water resources in the basin. But the legitimacy of the MRC system has been eroded due to the lack of participation by Myanmar and China, and in particular, the Chinese absence has made the four riparian states blind about the change of water regime due to the Chinese dams upstream. Environmental damages due to hydropower development might be possible, including a drop of fish yields, crop production, and damages to the river's ecosystems. Vietnam and Cambodia have already expressed their concerns over the dam construction towards China as well as Laos by pointing out detrimental impacts of the dams to their economies. China's move to collaborate with the other riparian states since 2010 has given a positive signal in terms of sustainable water management in the river. However, this phenomenon never confirms China's proactive contribution to the cooperative activities within the framework of the MRC system. Laos' initiative to build a new dam in the lower basin alarms those who are opposed to dam construction in the fear of its far-reaching damages to the environment. The question goes back to the year-long debate on policy priorities given to economic growth or the environment. The riparian states require wisdom based on a consensus about sustainable water use rather than hydropower development based on individual growth dreams.

Conduct a performance test through test jig about prototype zigbee sensor module with rf output power and unwanted emission test. This research task available early address when poisonous gas leaked from large industrial site and contribution for workers' safety at the enclosed space.
This paper investigates the development and aesthetics of Korean political theatre from its quickening period 1920s to democratization era 1990s. Political theatre before 90s developed an antithesis resistant movement toward Korean modern history that had been scattered with suppressing political circumstances such as colonial era and dictatorial government, the movement has powerful activity and social influences. Just like the 20 century political theatre had been quickened under the influence of Marxism at Russia and Germany in 1920s, Korea's political theatre began in socialism theatre movement form around the same time. Proletarian theatre groups had been founded in Japan and Korea, and developed into practical movement with organized connection. However, the political theatre movement in Japanese colonial era was an empty vessel makes great sound but not much accomplishments. Most performance had been canceled or disapproved by suppression or censorship of the Japanese Empire. The political theatre in liberation era was the left drama inherited from Proletarian theatre of the colonial era. Korean Theatre alliance took lead the theatrical world unfold activities based on theatre popularization theory such as 'culture activists' taking a jump up the line and 'independent theatre' peeping into production spot as well as the important event, Independence Movement Day Memorial tournament theatre. Since 1947, US army military government in Korea strongly oppressed the left performances to stop and theatrical movement was ended due to many left theatrical people defection to North Korea. The political theatre in 1960s to 70s the Park regime, developed in dramatically different ways according to orthodox group and group out of power. The political theatre of institutional system handled judgment on sterile people and had indirect political theatre from that took history material and allegory technique because of censorship. In political theatre out of institution, it started outdoor theatre that has modernized traditional performance style and established deep relationship with labor spot and culture movement organizations. Madangguek(Outdoor theatre) is 'Attentive political theatre', satirizing and offending the political and social inconsistencies such as the dictatorial government's oppression and unbalanced distribution, alienation of general people, and foreign powers' pillage sharply as well as laughing at the Establishment with negative characters. The political theatre in 1980s is divided into two categories; political theatre of institutional system and Madangguek. Institutional Political theatre mainly performed in Korea Theatre Festival and the theatre group 'Yeonwoo-Moudae' led political theatre as private theatre company. Madangguek developed into an outdoor theatrical for indoor theatre capturing postcolonial historical view. Yeonwoo-Moudae theatre company produced representative political plays at 80s such as The chronicles of Han's, Birds fly away too, and so on by combining freewheeling play spirit of Madangguek and epic theatre. Political theatre was all the rage since the age of democratization started in 1987 and political materials has been freed from ban. However, political theatre was slowly declined as real socialism was crumbling and postmodernism is becoming the spirit of the times. After 90s, there are no more plays of ideology and propaganda that aim at politicization of theatre. As the age rapidly entered into the age of deideology, political theatre discourse also changed greatly. The concept 'the political' became influential as a new political possibility that stands up to neoliberalism system in the evasion of politics. Rather than reenact political issues, it experiments new political theatre that involves something political by deconstructing and reassigning audience's political sense with provocative forms, staging others and drawing discussion about it.

This study has done to search for a solution to remove risk limitedly caused by separating weapon system acquisition from operation and maintenance at the view point of Logistic Commander who's responsible for stable operation and maintenance after acquiring weapon system. At the System development stage, unverified overhaul development plan may cause additional manpower and costs after the development, and furthermore it is likely to have risk to lower reliability of the military. Thus, research and development agency should write overhaul development plan at the System development stage, and it should be verified through evaluation and verification test. Secondly, during research and development, institutional supplementation is needed to calculate human and material resources writing overhaul development plan. Thirdly, it should be able to analyze proper operation & maintenance plan and cost for overhaul plan at the pre-investigation stage. Fourthly, the base which can develop overhaul concept and overhaul factors should be included in the need and need determination document. Lastly, for the weapon system which has small amount of high power figure, project management should be performed to be able to specify at the each acquisition level of weapon system to realize Article 28, clause 3 and 4 of Defense business law.
Major countries, such as the U.S., UK and Germany have reformed their national intelligence systems in the face of transnational, asymmetric and comprehensive threats since September 11, 2001 and have strengthened the intelligence capacity involved in countering terrorism and WMD proliferation, right/left extremism threats. The Korean Moon Jae-in government is preparing a reform plan to eliminate illegal political intervention and abuse of power by the National Intelligence Service(NIS) and to rebuild it as an efficient national intelligence agency for national security. In discussing the reform direction of the NIS, it is necessary to discuss in detail whether adopting a separate model of intelligence agencies to restrict domestic intelligence activities of the NIS and concentrate on foreign intelligence activities or establish new domestic intelligence agencies. Second, as for the issue of transferring anti-Communism investigation authority of the NIS to the police, it needs to be carefully considered in terms of balancing the efficiency and professionalism of intelligence agency activity in the context of North Korea's continuous military provocation, covert operations and cyber threats. Third, it should strive to strengthen the control and supervision functions of the administration and the National Assembly to ensure the political neutrality of the NIS in accordance with the democratization era, to guarantee citizens' basic rights and to improve the transparency of budget execution.

This paper is on the colonial history of the African continent. It was the origin of mankind, which was called "Hometown of humanity" or "Warm region" since ancient Greece and ancient Egypt. However, the place came to be the invasion target of Western powers. Western nations, based on strong military and economic power, slaughtered sturdy African men and stripped off major resources for their own interests, devastating many parts of the African continent since the 15th century. This unfortunate history seems to have met a happy ending in the mid-twentieth century, after the independence of many African nations that have been committed to national self-determination since World War II. However, African countries have not been recognized as equal partners in the international arena. They were only poor and powerless countries that could be maintained only through the aid of advanced nations like France, as before. Of course, in the 21st century, Africa has begun to be thought to be a new market with high potentiality for development. Various countries, including India, China, Russia and Brazil, as well as major European countries, which have traditionally maintained friendly relations with France, are making efforts to increase their influence in Africa. Therefore, to understand this new trend, it is necessary to give a top priority to grasp the colonial history surrounding African continent.
This study analyzes the behavior of China in the international context of East Asia based on the in-depth understanding of Confucian Sino-centrism. The rise of China is a dream to be realized for Chinese while actually it is regarded as new threats for the neighboring countries. It is therefore no surprise that the neighboring countries that once subordinated themselves to China voluntarily feel threatened by the resurrection of China. The reason is that China is pursuing hegemony based on China's stronger power rather than seeking culture and morality as they did in the past. The new hegemonic pattern seems not to contribute to the China's profit, only to increase the tension among North East Asia. That's because the neighboring countries are active in expanding military expenses with strengthening ties with the US. In this context, is it possible that China can rise gently without threatening the neighbors? There must be a way. It is that China will be born as a superpower with Confucian morality as the way the Confucian Sino-centrism is intended. When the neighboring countries are impressed by the way the China treats them with moral virtues, the leadership of China will be strengthened of itself. It is the most desirable way of realizing the dream of China.
The purpose of this article is to verify whether recent political change in Thailand and the Philippines is temporarily shown "democratic recession" or "returning to authoritarianism". For the purpose this research establishes three propositions based on previous academic researches of political change. The is to verify characteristics of liberal democracy based on democratic procedures and institutions as well as civilian control over the military. The is to analyze the characteristics of authoritarianism such as the control over individual freedom and rights, concentration of power, and populist ruling behavior contrary to constitutionalism. The last one, , is to check either the coincidence or discrepancy between democratic institutions and popular understanding of democracy during democratic transitions. The finding through testing those propositions is that recent political change in two countries is more likely "returing to authoritarianism" rather than provisional "democratic recession". Implications of the finding has two aspects. One is that the only change in democratic procedures and institutions including the competition among political parties and peaceful change of governments are not enough to ensure a successful transition to liberal democracy. The other is that a half-democracy lacking the change of popular understanding and belief toward democracy as well as democratic practices cannot survive long enough. These are confirmed through this study on the cases of Thailand and the Philippines.
Low-Orbit satellite mobile networks can provide services through miniaturized terminals with low transmission power, which can be used as reliable means of communication in the national public disaster network and defense sector. However, the high traffic environment in the emergency preparedness situation increases the new call blocking probability and the handover failure probability of the satellite network, and the increase of the handover failure probability affects the QoS because low orbit satellites move in orbit at a very high speed. Among the channel allocation methods of satellite communication, the FCA shows relatively better performance in a high traffic environment than DCA and is suitable for emergency preparedness situations, but in order to optimize QoS when traffic increases, the new call blocking and the handover failure must be minimized. In this paper, we propose LEO-DBC (LEO satellite dynamic beam width control) technique, which improves QoS by adaptive adjustment of beam width of low-orbit satellites and call time of terminals by improving FCA-QH method. Through the LEO-DBC technique, it is expected that the QoS of the mobile satellite communication network can be optimally maintained in high traffic environments in emergency preparedness situations.

Because the cage assembly serves as the launch platform, an accurate aim is essential to ensure shooting accuracy for the target. On the other hand, the abnormal rotation of the cage due to the directional errors of the K-MLRS has continuously caused quality problems. The quality problem of weapon systems may have a negative impact on the military's power loss. In this study, improvement plans were derived by examining the defects and analyzing the directional errors of the K-MLRS launcher. In addition, all possible causes of directional errors were derived from the flow diagram for cage directionality. Based on the results, the defense design through the software program was intended to prevent the loss of direction. Through this study, the signal error of the resolver was improved by preventing unspecific signals in the data. Furthermore, the directional judgment method was improved to minimize the impact of data distortion. Lastly, directional storage and verification methods were improved so that data for the cage rotation direction would not be affected by errors. For the design improvement method, the reliability was verified through the system applicability. This study is expected to be a reference for failure analysis and design for similar weapon systems in the future.
