This research discusses the application of the control variables to achieve a more precise estimation for the target response in queueing network simulation. The efficiency of control variable method in estimating the response depends upon how we choose a set of control variables strongly correlated with the response and how we construct a function of selected control variables. For a class of queuing network simulations, the random variables that drive the simulation are basically the service-time and routing probability random variables. Most of applications of control variable method focus on utilization of the service time random variables for constructing a controlled estimator. This research attempts to suggest a controlled estimator which uses these two kinds of random variables and explore the efficiency of these estimators in estimating the reponses for computer network system. Simulation experiments on this model show the promising results for application of routing probability control variables. We consider the applications of the routing probability control variables to various simulation models and combined control variables using information of service time and routing probability together in constructing a control variable as future researches.

This paper attempts to analyze the role of Nigeria's current President Major (Rtd) Mahammudu Buhari and the immediate past President Goodluck Jonathan in dealing with the Boko Haram Insurgency in Nigeria. Nigeria has not been without its fair share of conflict. In fact, no decade of post-Independent Nigeria has been conflict free. With several coups, general strikes and a civil war, Nigerians have had to experience some of the most sordid tragedies arising from difference of opinions and distrust. It is interesting to mention that the conflict in Nigeria has not received the needed attention as it were. The leadership of Goodluck Jonathan did not receive the same effort and cooperation as compared to Muhammadu Buhari who came into office in May 2015. This paper argues the important roles played by the two Nigerian leaders which either aided or prevented collaboration. Goodluck Jonathan was perceived as a weak and indecisive leader whose leadership failed to effectively handle the Boko Haram insurgency. Muhammadu Buhari assumed office with a lot of high hopes and expectations from the Nigerian population and the international community to tackle the Boko Haram insurgency.

A well-known historian, Ahn Jeong-Bok(Sun-Am, 1712~1791) was an expert on the country village community. He was a scholar of the "Nam-In" group, who was excluded from the corridors of power in those days. He kept on the move in various parts of country villages from his childhood. After settling down in Deok-Gok, Kwang-Ju, he stayed in the place devoting himself to the self-culture and the literary works. By his surrounding of environment, he had an academic interest in a concrete science rather than metaphysics and country villages rather than the central city. He considered the country villages as the link holding between a family and a country and had the conception of a confucianist community based on country villages, emphasizing the practice of confucianist virtues in everyday life. First of all, his confucianist community was the community based on country villages. He thought that the enlightenment was a matter of great importance for solving problems in country villages. As a solution to those problems, he suggested Hyang-Yak, the self-governed regulations of country villages. In his own village he made the self-governed rules Dong-Yak. When he was a provincial governer of Mok-Cheon, he put Hyang-Yak, the self-governed regulations of country villages in operation. It aimed for a kind of gentry-centric country village community. But Hyang-Yak was the regulations based on the agreement with each other, stressed the regard on the popular mind and the setting the pace of the gentry, and aimed for the harmony and order in a community through the practice of moral virtues in daily life. On the other hand, he had a conception of a country village's academic community. He thought of the development of educational intuitions as a pressing need of the enlightenment of country village. With young people he read confucianist books with comments in a village school, Seo-Jae. In his seventies, he made and put the self-regulations for academic community, Hak-Yak, in operations. It is considered that Hak-Yak was an example of his idea of academic community and his point of view on learning, which emphasized on the coincidence with reading and practice.

Suam(遂庵) Kwon Sang-Ha(權尙夏) was a very important character in the late Chosoen Dynasty. He was a representative of the academic circles(school of Uam) and political circles(Nolon; 老論) after Uam(尤庵) Song Si-Yeol(宋時烈, 1607-1689). He represented learning and thought and undertaking of his academic circles and political circles, and handed down to his pupils. He thought his mission was "lighting the laws of heaven and aligning the human mind," "stopping the heretical study and repulsing uncivilization", to reform good virtues of humanity and justice. Kwon Sang-Ha was a successor of Song Si-Yeol, He succeeded learning and thought of his teacher and practiced "Upright"(直) and the Thought of ChunChu(春秋). He emphasized "Upright" as a fundamental principle, like his teacher. He thought ChuHsi(朱熹, 1130-1200) was the master who had inherited the spirit of Confucianism and Chosoen was the only country to successfully inherit this spirit of Confucianism. He declared any study counter to the study of ChuHsi as a rebellious pursuit. Therefore he rejected all other studies. He tried to "stop the heretical 'ism' and repulse uncivilization" and present this ideology as 'the Right way of Human Society(世道)'. He made efforts to reorganize books of ChuHsi to make perfect Book of righteousness with Song Si-Yeol. And he established Hwayang shrine, MandongMyo(萬東廟), Deabodan(大報壇) etc, in memory of fidelity and large rightness. Kwon Sang-Ha did these undertaking to establish 'Public morals and the Right way of Human Society(世道)' with self-confidence. In Dispute on the nature of man and animal(人物性同異論), he gives his approval to Han Won-Jin's opinion. Han Won-Jin's opinion was "the nature of man and animal is Different"(人物性異論). Whenever serious political accidents occurred, he took the lead to protect his teacher, Song Si-Yeol. The reason he did this was not because of his personal feelings for his teacher, but because of promoting 'Public morals(世道)' and 'Confucianism.' Kwon Sang-Ha regarded Mind control Law of "Upright" and the thought of ChunChu as his moralities, and was concerned about real politics and opposed social irregularities. Kwon Sang-Ha succeeded Song Si-Yeol's thought of "Upright" and volition of making an inroad on the Chung(淸), and gave to his political circles(Nolon; 老論) as a law of mind and mission.

This study surveys and reviews political change, economic performance, and regional cooperation that were carried out in 2016 by Southeast Asian countries and ASEAN. This paper reports that what has followed the inauguration of new governments in Myanmar, the Philippines, Vietnam, and Laos fails to live up to the expectation and optimism that arose in the aftermath of elections and party congresses that took place in the first half of the year. In other countries such as Malaysia, Thailand, and Cambodia, where authoritarian regimes are faced with strong oppositions, the prospects for democratic change worsened to a substantial degree, as schisms and internal strives complicated the opposition camp as a result of instigation and intervention by the authoritarian leaders and their followers. In stable political systems, both democratic and authoritarian, no significant changes that may entail serious political implications were noticed. In 2016, the national economy of almost each and every country continued its slow but steady recovery that had started in 2014 and grew by 5% on the average. For 2017 onward, however, the earlier optimism that it would grow at least as fast dimmed down as uncertainty about the world economy looms larger due to the unexpected win by Donald Trump as U.S. president and the expected 'hard landing' of the Chinese economy around 2018. ASEAN declared the launch of the ASEAN Economic Community (AEC) only one day before the New Year, but its track record looked already bad and unpromising by the end of 2016. ASEAN leaders were tied up by their domestic politics and affairs too tightly to take time off to work seriously to observe the schedule as laid out in the AEC Blueprint 2025. Korea's relationship with Southeast Asian countries and ASEAN was "as good as it gets" in 2016 as ever but could become subject to tough review in the near future, if the Ministry of Foreign Affairs is found out to have been implicated in the ongoing Choi Sun Sil scandal and if the opposition wins the next presidential election to be held by this year.

In the presidential political system, the word of the president has great influence on the formation of national policy and the decision-making process. Policy priorities are determined according to the president's ideology and core values, and various policies are established and executed according to the priorities. Therefore, this paper analyzes the contents of the president's speech. Since the president's speech is a semantic datum, in order to analyze unstructured text, big data analysis is conducted through the methods of machine learning and deep learning. In this study, the president's speech at the "National Sea Day" commemoration was obtained 1996 onwards and analyzed using topic modeling. As a result of the analysis, all the presidents' speeches were delivered with a view of the ocean that was consistent with the direction of their administration. It was confirmed that the ocean-industry-resource topics, which are the intrinsic values of the ocean, were not damaged and consistently emphasized by all presidents.

90년대 후반에 내전이 끝난 캄보디아는 태국이나 베트남에 비해 정치, 경제적으로 안정되지 못한 상황이다. 어린이들에 대한 교육환경 역시 좋지 않아, 기초과학을 접할 수 있는 기회가 적을 뿐 아니라, 대도시를 벗어난 곳에서는 과학교육이 거의 이루어지지 못하고 있는 현실이다. 수도 프놈펜에서 북서쪽, 차편으로 4시간 거리에 있는 뿌삿시 끄로압에서 몬테소리 유치원을 운영하고 있는 한국봉사단의 요청으로 한국천문학회는 2016년 상반기에 관심있는 학회 구성원들을 중심으로 천문학 교육 프로그램 지원단을 구성하여 6월말부터 25일까지 2주 동안 현지 어린이들을 대상으로 천문학 교육 프로그램을 수행한 바 있다. 모두 50여명의 초, 중등 학생들이 참여하여 성황리에 마무리된 캄보디아 교육 프로그램의 성과와 시사점, 앞으로의 계획 등을 소개하고자 한다.
