지오센서 네트워크에서 에너지 효율성을 지원하는 바이트코드 기반 데이터 서비스 미들웨어 구현

홍승태,윤민,장재우,Hong, Seung-Tae,Yoon, Min,Chang, Jae-Woo 한국공간정보학회 2010 한국공간정보학회지 Vol.18 No.4

최근 모바일 기기 및 우선 통신의 발달로 인하여 지오센서 네트워크가 실생활의 다양한 분야에서 활용되고 있다. 이에 따라 센서 노드의 제한된 에너지를 효율적으로 사용할 수 있는 미들웨어에 대한 연구가 활발히 진행되고 있다. 그러나 기존 미들웨어들은 센서 노드의 고유한 처리 능력 몇 가능을 고려하여 개발하지 않았기 때문에, 제한된 시스템 자원만을 사용하는 센서 노드에서는 운영이 불가능하다. 따라서 본 논문에서는 지오센서 네트워크에서 에너지 효율성을 자원하는 바이트코드 기반 데이터 서비스 미들웨어를 설계 및 구현한다. 제안하는 미들웨어는 첫째, 하드웨어 추상화를 지원하는 데이터 관리자와 최소한의 바이트코도 명령어를 통하여, 센서 노드에 최적화된 기능만을 제공한다. 둘째, 불필요한 데이터를 제거함으로써 데이터 전송량을 최소화하는 데이터 집계 질의처리 및 데이터 필터링을 통하여, 센서 노드의 에너지 효율성을 향상시킨다. 마지막으로, 기존 연구인 SwissQM과의 성능 평가를 통해 제안하는 미들웨어가 데이터 전송량과 평균 에너지 소모량 측면에서 에너지 효율적임을 보인다. Recent development in wireless communication and mobile positioning technologies make geosensor networks widely used in the various fields of real world. As a result, much research has been done on the middleware that uses limited energy resources efficiently. However, because traditional middleware does not consider the characteristics of sensor node, such as computing power and specification, the existing middleware call not support the sensor nodes with only the restricted system resource. Therefore, in this paper, we design and implement a new Bytecode based Data Service Middleware supporting energy efficiency in geosensor networks. At first, the proposed middleware provides the optimized functions for sensor nodes by using minimum by tee ode instruction set and data manager supporting hardware abstraction. Secondly, the proposed middleware increases the energy efficiency of sensor node through both data aggregation query processing and data filtering that minimize data transmission by eliminating unnecessary data. Finally, we show from our performance analysis that the proposed middleware is more energy efficient than the existing SwissQM.

Korea has been ranked at the top consecutively in UN e-Government Survey. This fact reflects consistent efforts by public institutes in Korea. However, there were some duplicate efforts and inefficiency in the investment into IS(information systems). In other words, management and decision making on e-government have yet to improved. Accordingly, governmental institutes have long been promoting policies for EA in order to carry out and manage effectively IT projects including the e-Government projects. EA is being regarded as a means to facilitate IT Governance for systematic management of IT projects, A major objective is to firmly establish the decision making process for IS investment through EA, since the each institute is a large organization with so complicated and specialized demand for IS. As a result, systematic decision making is becoming quite difficult. Thus, this study attempts to identify different types of IT investment decision making and to figure out the relationship between the decision types and the organizational performance of public institutes where EA was implemented.

남송 전기 ‘태평 분식’의 정치적 배경과 전개 양상

“Reign of peace as window dressing” designed and executed by Gao-zong and Qin hui in the period of Shao Xing, was rooted in the legitimacy flaws of the South Song regime. Emperor Gao-zong, who ascended the throne at a time when the Northern Song were destroyed due to the invasion of Jin(金) Dynasty, and Emperor Hui-zong and Qin-zong were taken prisoner, he failed to follow the normal procedure of throne succession. In addition, Song Dynasty abandoned central districts which was the symbol of geographical and spatial legitimacy, and fled to the south of Chang Jiang by force, suffered fatal damage in the legitimacy of ruling power. Because the authoritative task of Revenge and Recovery conflicted with common goal “the Peace Treaty” of Gao-zong and Qin hui, They had to find a more elaborate political solution. One of the most distinctive features of the development of “Reign of peace as window dressing” in early South Song Dynasty is that "disaster and ominousness (災異)" was completely covered up, "auspicious sign(祥瑞)" is exaggerated, and even artificial manipulation was not discouraged by Qin hui. On the other hand, Gao-zong pretended to be a monarch who was immersed in the Confucian Bible ChunQiu, which embodies the meaning of “honour the king and drive off the barbarians(尊王攘夷)” “Honour the king” meant the legitimacy that he still had to have strong power as a emperor, and “Drive off the barbarians” could show that he was still trying to revive the nation. Most of all, unlike Qin Hui"s peacemaking, which only exaggerated “auspicious sign”, Gao-zong was able to disguise himself as a timid monarch who accepted heaven"s warnings. The two may look contrary to each other, but politically they could have a mutually complementary effect.

宋代 荀子 비판과 新儒學 성립의 관계

홍승태(Hong, Seung Tae) 동양사학회 2018 東洋史學硏究 Vol.144 No.-

Confucianism, which was only a school of disciples in the Spring and Autumn period, was adopted as the political ideology of the nation for the first time in the Han Dynasty. However, Confucianism itself remained in the interpretation of rudimentary scriptures following the restoration of lost scriptures. When Confucian thought, which had been overwhelmed by the influence of Buddhism and Taoism for a long time, It came to a new turning point in the period of late Tang Dynasty to early Song. The first work that the Confucian scholars of the late Tang and early Song dynasty, representing Han Yu, who was able to oppose the Buddha and the Taoist, established the Confucian scholarship system after Confucius. As a figure connecting Confucian scholarship system with Mencius, Xun-zi was also evaluated as the Great Confucius, and his name was raised in the genealogy. However, in the middle of the North Song, contrary to the position of Mencius, Xun-zi was subjected to severe criticism of the Song Dynasty, and even suffered from `heresy`. The main reason was focused on his theory of human nature and relation of legalism. His theory that human nature is fundamentally evil is a point of confrontation with Mencius` principle of good nature, theory of human nature has become a crucial criterion to measure authenticity of Confucianism. The first task that Confucian scholars should solve in order to establish neo-Confucianism was to clarify the system of Confucianism theoretically. In this paper, Critique of Xun-zi in Song dynasty was approached from the viewpoint of the theorization of the system and the establishment of a new theory in the process of neo-Confucian formation. The criticism of Xun-zi was an ideological and philosophical work that was firstly required in the process of organizing the system to establish Neo-Confucianism. Free criticism and doubt about the main scriptures of Confucianism became a very important condition for the birth of the Neo-Confucianism.

[중국 근세Ⅰ] 다양화 · 다각화의 지속과 모색

홍승태(Hong, Seung-Tae) 역사학회 2016 역사학보 Vol.0 No.231

In research trends of Song-Liao-Jin-Yuan history from 2014 to 2015, the most remarkable point can be abbreviated or expressed by the few words, “multi-perspective approach and diversification of method”. The number of research papers which were submitted in 2014~2015 was 89 papers. It has more than doubled in the last period(2012~2013), and was the highest numbers recorded from every periods since 2000. Research of Liao-Jin and Mongol empire history has continuously maintained qualitative development until this period. but Study of Song history, which has been stalled during last periods, occupied about half of all papers in this period(2014~2015). A significant increase in the number of papers of Song history, is not due to increase of number of researchers or numbers of papers per a person. It results from submitted thesis of various research fields, included literature, archeology, palaeography, architecture studies, science, martial arts aside from bibliographic history of Song dynasty. Considering the civilizational status of Song history, It is very important that Korean researchers of various categories have a lot of attentions and opinions on the matters of this era. and it is very remarkable that the research of Liao-Jin history has tried to reconstitute the reflection of history from many different perspectives and methods. History studies of Mogol empire and international relations, which have had a qualitative development since 2000, try to make interpretations of history from new perspectives and methods.

『치평요람(治平要覽)』에 수록된 『당감(唐鑑)』의 史論과 『제범(帝範)』

洪承兌 ( Hong Seung Tae ) 중국사학회 2019 中國史硏究 Vol.0 No.123

The Chipeong Yolam (治平要覽; “The General Survey for Governance of Peace and Prosperity”) completed in King Se-jong’s reign of the Joseon Dynasty (1445), is a history book compiled to read the main points of Confucian politics. It is a masterpiece of 150 volumes, which chronicled major historical events from Zhou dynasty(周朝) to Yuan dynasty(元朝) and parts of Ming dynasty. In the 23rd year of King Sejong's reign (1441), King Se-jong ordered scholars of Jiphyeonjeon(集賢殿) to compile the book and completed it after four years of writing. This book is not just a history book compiled by listing historical facts, but a kind of political textbook that selects content that will help the actual politics of the Joseon Dynasty, the Confucian country. It summed up the essence of Confucian politics from the historical experience of the rise and fall of the Tang Dynasty and political success and failure. This book valued Tang history so much that it devoted 25 volumes out of a total of 150 volumes to the history section of the Tang Dynasty. Most of the historical facts of Tang cited Sima Guang’s “Comprehensive Mirror in Aid of Governance” by the history of the Song Dynasty, and the historical review cited Fan zu yu’s “Tang’s History as a Mirror” compiled the Tang Dynasty history section of “Comprehensive Mirror in Aid of Governance”, where he wrote his own review book separately. His historical review assessed the events of Tang Dynasty history and the actions of the monarch based on the principle of strict Confucian ethics. This review book is one of the most famous historical reviews in China, and it was highly regarded as a book that monarchs and bureaucrats had to read throughout the Joseon Dynasty. It contains a large number of historical reviews by Fan Zuyu, a Confucian scholar and historian of the Song Dynasty. Through his perspective, he tried to find the cause of the rise and fall of the Tang Dynasty, and at the same time included in detail the entire 12 chapters of “A Model of Monarchy”, which summed up the secret of the political success. “A Model of Monarchy”(12-chapter), written by Emperor Taizong of Tang Dynasty, laid out the core of the monarchy, including self-discipline by the monarch and the management of political power.

남송(南宋) 악비(岳飛)에 대한 조선왕조의 충신(忠臣) 현창과 그 의미

홍승태 ( Hong Seung Tae ) 중국학연구회 2020 중국학연구 Vol.- No.93

이 논문은 조선시대 남송 악비에 대한 충신 현창과 그 의미를 분석하였다. 악비는 ‘진충보국’의 상징적인 인물로, 충효의 덕목을 유교사회의 근간으로 삼은 조선왕조의 국시에 정면으로 부합되었다. 조선전기 세종의 『삼강행실충신도』에 선정된 악비는 임진왜란이 발발했던 선조시대에 『정충록』의 발간을 통해 ‘충무’의 상징으로 현창되었다. 왕권과 붕당의 갈등이 극심했던 숙종과 영조 때에도 악비에 대한 현창은 지속되었다. 본고는 악비에 대한 충신 현창의 근원적인 배경과 그 특수성을 송조와 조선왕조 두 왕조가 갖고 있었던 통치이념과 체제의 상호 유사성, 그리고 유교적 문치주의(혹은 문관정치)가 갖고 있는 근본적인 한계점으로부터 접근하였다. 송조의 신유학(성리학)과 유교적 문치주의는 조선왕조가 지향하는 사상적ㆍ정치적 감계의 대상이었다. 특히 조선왕조가 중시한 송조의 명신들 가운데 악비는 농민 출신이자 ‘武臣’이라는 신분적 특수성을 가지고 있었다. 이러한 특징은 전란의 위기와 당쟁의 파국 속에서 왕권과 군사력의 강화라는 정치적 목적뿐만 아니라 ‘존왕양이’와 ‘대일통’의 대의명분과도 부합되었다. General Yue Fei(1103∼1142) of South Song Dynasty was highly respected in the Joseon Dynasty as a symbol of loyalty. In the Confucian kingdom of Joseon, there was a shrine to commemorate and honor him, and also published books that chronicled his life. The Sam Chung(三忠) Shrine which commemorated three loyal great men Zhuge Liang(181∼234), Yue Fei, Wen Tianxiang(1236∼1283) was established in 1750. Zhuge Liang(181∼234) as the chancellor and regent of the state of Shu Han during the Three Kingdoms period. Wen Tianxiang(1236∼1283) was a scholar-general in the last years of the South Song Dynasty. And also Utmost Loyalty: Yue Fei’s Biography was published in 1585 by King Seon-jo of Joseon, republished during the reign of King Yeong-jo, the book contains Yue Fei’s biography as well as poems and sentences written by his Descendants. The Joseon Dynasty has always regarded the Song Dynasty as an example of Confucian politics and Neo-Confucianism. In particular, to strengthen royal power and military power, Joseon established a shrine to commemorate Yue Fei as a loyal subject and published a book containing his life story.
