정동준,이두용,임성진,Jeong, Dong-Jun,Lee, Du-Yong,Im, Seong-Jin 대한기계학회 2000 大韓機械學會論文集A Vol.24 No.8

As recent production facilities are usually operated with unmanned material-handling system, the development of an efficient schedule with deadlock avoidance becomes a critical problem. Related researches on deadlock avoidance usually focus on real-time control of manufacturing system using deadlock avoidance policy. But little off-line optimization of deadlock-free schedule has been reported. This paper presents an optimization method for deadlock-free scheduling for Job-Shop system with no buffer. The deadlock-free schedule is acquired by the procedure that generates candidate lists of waiting operations, and applies a deadlock avoidance policy. To verify the proposed approach, simulation resultsare presented for minimizing makespan in three problem types. According to the simulation results the effect of each deadlock avoidance policy is dependent on the type of problem. When the proposed LOEM (Last Operation Exclusion Method) is employed, computing time for optimization as well as makespan is reduced.

정동준 ( Jeong Dong Jun ),김홍률 ( Kim Hong Lyul ),신만용 ( Sin Man Yong ) 한국농림기상학회 2003 한국농림기상학회지 Vol.5 No.3

N/A This research was conducted to investigate about structural characteristics of vegetation by change of the environmental factors for prolific open-pollinated progeny forest in Pinus koraiensis stands. Stand slope of Kapyung area was slower than Youngdong area. On the other hand, contents rate of the soil chemical properties in Kapyung was lower than Youngdong area. And relative intensity of light was higher Youngdong than Kapyung area. On the whole, growth of the Pinus koraiensis was more dominant Kapyung area than Youngdong Analysis result of the relative density, - frequency, - coverage and importance value to shrub layer in each local stands, Quercus mongolica and Quercus acutissima were dominant species in Kapyung area. Dominant species In Youngdong area was Quercus acutissima. In Kapyung area, appearance species of the vegetation layer was consisted that live in moist soil and shaded lot. Youngdong area showed fewer species than Kpyung area. Species diversity of shrub and vegetation layer in Kapyung and Youngdong area was higher than Youngdong. This result was judged by slope difference between each areas. Kapyung area need enforce thinning and Youngdong area conduct tending management on shrub layer.

드라마 · 영화에 나타난 한국고대사

정동준(Jeong, Dong-jun) 한국고대사학회 2016 韓國古代史硏究 Vol.0 No.84

이 글에서는 2000년 이후 제작된 영상물을 정리한 후, 그 ‘기획의도’를 분석하여 유형화하고, 구체적으로 몇몇 영상물을 분석하여 시대상 표현이나 현대적 의미까지 분석하여 평가해 보았다. 그 내용은 다음과 같다. 2000년 이후 제작된 19개 영상물을 정리해 보면, 대상시기는 7세기, 대상국가는 고구려, 주인공은 왕실 관련 인물, 방영(개봉)시기는 2005~2009년, 장르는 퓨전이 가장 많았다. 특히 2005~2009년에 동북공정에 대한 대응 차원에서 고구려·발해 관련 드라마가 집중적으로 제작되었다가, 그 이후에는 대상국가나 주인공이 다양화되는 경향에 있었다. 다음으로 기획의도를 분석해 보면, ①민족주의(국수주의)에 바탕을 두고 제국을 꿈꾸는 것이 8개, ②개인이나 국가를 재평가하려는 것 7개, ③새로운 소재와 내용을 보여주려는 것이 4개였다. 복수의 영상물에서 공통적으로 나타나는 왜곡된 시대상으로는 ①‘황제’(‘제국’) 호칭과 연호, ②중국과의 대결 중심으로 표현된 대외정책, ③광활한 대륙의 지배를 들 수 있었다. 영상물에서 잘 표현된 시대상의 사례로는 ①김유신에 대한 재해석, ②무왕의 탄생비밀에 대한 해석, ③정사암회의에 대한 묘사, ④고대사회의 신비주의적 정치에 대한 해석 등이 있었다. 영상물에서 맥락 없이 과도하게 표현된 현대적 의미의 사례로는 ①단일민족적 묘사, ②멜로드라마 구도를 차용하여 내용상 사적 영역이 지배하는 경향을 낳았다는 점을 들 수 있었다. 영상물에서 잘 표현된 현대적 의미의 사례로는 새로운 인물의 부각이나 인물에 대한 재해석을 들 수 있었고, 현실 사회에서 벌어진 정치적 사건을 고대적으로 풍자한 개별 작품의 사례도 있었다. This article researched the videos on ancient Korean history since 2000 and then classified them by analyzing their purposes, and reviewed several videos of them by analyzing historical representation or contemporary meaning. Among 19 videos produced after 2000, we can find that most of them described royal family, Goguryeo and the 7th century with the genre of fusion historical drama. Most of those videos was televised or released between the year of 2005 and 2009. Notably, the dramas regarding Goguryeo and Balhae were produced intensively to cope with China’s Northeast Project from the year of 2005 to 2009. Then, after that, the countries or protagonists described in dramas or movies have become varied. The purposes of 19 dramas and movies can be analyzed as follows. Motives of 8 videos’ were dreaming the empire based on the nationalism or chauvinism. 7 videos intended to revaluate certain individuals or ancient countries. 4 videos tried to show new materials and stories. We can point out that common distorted reflection of the historical era from 19 videos such as using the title of an emperor or empire and era name, foreign policy described mainly as the conflict with Chinese dynasty, and the rule over the vast continent. A number of the examples from the videos were well depicted: reinterpretation of Kim Yushin(金庾信), new interpretation of the secret of King Mu(武王)’s birth, depiction of the council of Jeongsaam(政事巖) and interpretation of the mystical politics in ancient society. A few contemporary meanings without the context were inserted excessively in the videos. They were the description of a nation-state and melodramatic story controlled by private space. Other examples well described in the modern context were emergence or reinterpretation of new characters. There was also an individual work satirizing current political issue with the ancient mode.

백제의 중앙통치조직에 대한 연구사 검토

정동준 ( Dong Jun Jeong ) 백제학회 2015 백제학보 Vol.0 No.13

이 글에서는 각각의 분야를 나누어 백제의 중앙통치조직에 대한 연구사를 정리한 후, 그 문제점과 향후과제를 살펴보았다. 또 그와 함께 앞으로의 연구과제에 대해서도 언급함으로써 향후 연구에 도움을 주고자하였다. 좌평제에 대해서는 6좌평의 성립시기에 대한 3가지 학설이 있었고, 이것이 상좌평에도 적용되었다. 22부사에 대한 연구는 대부분 정치제도사 전반을 설명하는 일부로서 이루어져 내용이 심화되지 못하였다. 기타 관직에 대한 연구는 아직 각각의 관직이 따로 연구되는 경향이 강하여, 정치구조의 측면에서 연관지어서 종합적으로 파악하려는 노력이 필요하였다. 관등제, 회의체, 권력구조 등에 대한 연구는 기본적으로 숫자가 적은데다가, 연구자마다 견해는 물론주목하는 바가 달라서, 아직 이렇다 할 쟁점이 있다고 하기는 어려웠다. 남북조 관제에 대해서는 본래 어떠한 속성의 것이었고, 백제에서는 어떻게 운용되고 있었는가를 살피지 못하는 경향이 있었다. 보완해야 할 점은 주변국가와의 엄정한 비교, 제도 수용에서 수용경로와 매개체의 존재, 사료의 성격 인식등이다. 향후의 과제로는 새로운 자료에 의해 연구할 수 있는 논리나 방법론의 개발, 새로운 자료의 출현에 의해 연구할 수 있는 토대 마련, 중앙통치조직과 지방통치조직을 연계시켜 파악하는 논리나 방법론의 개발등이다. This article aims to examine the studies on Baekje’s central government organization in each field and then check the problem and next task of them. Also this paper tried to help another study by discussing research project in the future. There have been three theories about establishing period of Jwapyeong (the first official rank) system in the government organization. These theories were applied to study about Sangjwapyeong, the prime minister in the government. Studies on 22 offices, Busa, were so partially performed to explain the whole political system that they could not be deepened. Many studies about other official positions have been performed so respectively by each position that we should make a effort to understand the official positions comprehensively in the relation of political structure. Studies about Gwandeung(the official rank) system, the council, and the power structure have had only a few researches. Each scholar have had so different point and idea about them that prominent issues hardly appeared. Original attribute of bureaucracy in North and South Dynasties in China and its use in Baekje have not been examine denough. We should redeem several things in the studies about points Baekje’s central government organization like precise comparison with neighboring countries, existence of the accepting route and media in the acceptance of political system, and understanding the character of the historical materials. Our next task is to develop the available logic and the methodology with new materials, to prepare research basis by the appearance of new materials, and to comprehend the central and provincial ruling organization in the interrelation between them.

동아시아의 典籍交流와 『論語』 목간

정동준(Jeong, Dong-jun) 한국목간학회 2020 목간과 문자 Vol.0 No.24

이 글에서는 쌍북리 『논어』 목간이 동아시아의 전적 교류에서 가지는 의미를 파악하기 위해서, 쌍북리『논어』 목간의 출토상황과 선행연구, 한국의 『논어』 목간 출토사례를 정리한 후, 출토된 『논어』 간독의 특징을 중국왕조 및 고대 일본과 비교하였다. 정리하면 다음과 같다. 쌍북리 출토 『논어』 목간은 신라 지역에서 출토된 것으로 보이는 봉황동 · 계양산성 『논어』 목간과 차이가 적지 않았는데, 다면체의 觚라는 점만 공통점일 뿐 출토지가 당시의 지방이 아니라 왕경이고 남은 것이 완형에 가까워서 좁고 장대한 형태가 아닌 데다가 學而篇의 맨 앞부분을 적었다는 차이가 있었다. 비교대상을 북한 · 중국 · 일본 등의 『논어』 간독으로 확대하였을 경우, 쌍북리 출토 『논어』 목간은 규격이라는 측면에서 漢代의 서적간과, 봉황동 · 계양산성 『논어』 목간은 1章1觚라는 기재방식에서 河西 지역 출토서적목간과 공통점이 있었다. 둘 모두 중국 출토의 『논어』 간독보다는 여타의 서적간독과 공통점이 있었던 것이다. 고대 일본의 경우 學而篇의 기재나 휴대용 학습 목적은 백제 즉 쌍북리 출토 『논어』 목간의 영향이, 대형 목간에 1章1觚라는 기재방식을 채택하여 공공의 교육 목적으로 사용하는 것은 봉황동 · 계양산성 『논어』 목간의 영향이 있었다고 할 수 있었다. 쌍북리 출토 『논어』 목간의 저본에 대해서는 『논어집해』와 『논어의소』 중 하나라고 생각되지만, 현재 어느 한쪽으로 추정하기는 어려웠다. This article aims at understanding the meaning of the Analects of Confucius(論語) wooden tablets (abbreviated as ‘ACWT’ hereafter) excavated from Ssangbuk-ri(雙北里) in the exchange of classic books in East Asia. First, this article organized the current situation of excavation and preceding research of Ssangbuk-ri ACWT, and the excavation cases of ACWT in Korea. After organizing, this article compared the characteristics of the excavated ACWT with the Chinese dynasties and ancient Japan. The summary is as follows. Ssangbuk-ri ACWT is quite different from the Bonghwang-dong(鳳凰洞) and Gyeyangsanseong(桂陽山城) ACWT, which are considered to have been excavated in Silla region. The only thing in common is that it is a Gu(觚: the multi-faceted wooden tablets). The difference is that the excavation site of Ssangbuk-ri ACWT is not the local area but the royal city of kingdom at that time, and that the remaining ones are not narrow and elongated but close to the original form, and that the first part of the Xueer Chapter(學而篇) is written on it. When the comparison target was expanded to the ACWT of North Korea, China, and Japan, Ssangbuk-ri ACWT has common standard with the wooden tablets for books of Han(漢) dynasty, and Bonghwang-dong and Gyeyangsanseong ACWT have common writing method such as one chapter per one Gu with the wooden tablets for books excavated from Hexi(河西) region. Both have more in common with the wooden tablets for books than with ACWT excavated from China. In the case of ancient Japan, it is considered that writing of Xueer chapter and purpose of portable learning was influenced by Baekje represented by Ssangbuk-ri ACWT, and that the purpose of public education by adopting the one chapter per one Gu writing method in large size wooden tablets was influenced by Bonghwang-dong and Gyeyangsanseong ACWT. This article estimates that the original script of Ssangbuk-ri ACWT is one of Lunyujijie(論語集解) and Lunyuyishu(論語義疏), which are a variorum edition of the Analects of Confucius, but it is difficult to decide between the two.

프랑스 대혁명과 파리의 카페들 : 팔레 루아얄 지역을 중심으로

정동준(Dong-Jun Jeong) 한국세계문화사학회 2020 세계 역사와 문화 연구 Vol.0 No.57

팔레 루아얄은 오를레앙 가문을 대표하는 파리의 건축물이다. 오를레앙 가문(섭정 공-평등 공)은 루이 14세에서 루이 16세로 이어지는 부르봉 가문과 오랫동안 프랑스의 통치권을 두고 갈등과 견제를 주고 받았는데 그때마다 팔레 루아얄의 위상도 변하였다. 즉, 팔레 루아얄은 루이 14세 사후 오를레앙 섭정 공이 궁정쿠데타로 권력을 장악하고 그곳을 리모델링하면서 정치적 중심지로 떠 올랐다. 이후 팔레 루아얄은 오를레앙 평등 공에 의해 다시 한번 대대적인 리모델링이 되면서 공권력이 미치지 않는 공간이 되었고 무엇보다 모든 신분에게 개방된 공간으로 탈바꿈하였다. 따라서 섭정 공 사망후 루이 15세가 증조부의 왕궁(베르사유)으로 되돌아갔고 그의 계승자인 루이 16세 역시 베르사유를 중심으로 통치를 했지만 1789년 혁명의 기운이 팔레 루아얄을 품고 있던 파리에서 피어난 것은 우연이 아니었다. 그도 그럴 것이 1789년 초부터 점차 식량난에 대한 비판과 정치적 개혁의 요구가 분출하더니 그 해 6월-7월의 매일 저녁 1만 명 이상의 군중이 운집한 팔레 루아얄의 정원과 카페에서 정부를 비판하고 그 대안을 제시하는 연설들이 이어졌다. 18세기 중반부터 부풀어 오르고 있었던 계몽 및 혁명 사상이 이곳에서 매일 저녁 폭죽처럼 터졌던 것이다. 특히 팔레 루아얄에 자리잡은 카페들은 데물랭, 당통, 로베스피에르 같은 혁명가들에게 최적의 활동 장소가 되었으며 그것은 평등 공의 정치적인 야심과도 맞아 떨어지는 것이었다. This study is to explore Palais-Royal and its Cafés are some crucial places which lead the French Revolution. The estate of the House of Orléans and surrounded by powerful institutions and by the luxurious residential area, Palais Royal became a commercial[business, shopping] center. Many cafés gathered around this place. The position of Palais-Royal was changed depending on the political standing of the proprietor. House of Bourbon controled Versailles and House of Orléans controled Paris, and both are in rivalry each other. The régent of France(Philippe d’Orléans) succeeded on a court coup d’état. He took power away from the young king(Louis XV), whom the usurper detained near Paris. When the regent died in 1723, Louis XV returned to the Versailles Palace on which the governmental center moved from Paris. But Louis XVI was unable to resolve the religious, financial and political problems caused from his grandfather. Due to a drastic shortage of foods(1788-1789) and to a Parisian of fortune’s slip of the tongue(Jean-Baptiste Réveillon), numerous violent protests aroused over the country. Those above-mentioned let Philippe Égalité (duc d’Orléans) motivated to challenge the throne. During four years(1781-1784), Philippe Égalité renewed the palace enclosing a big rectangular garden surrounding all sides by huge buildings. He wanted to change the center for government from Versailles to Paris. Swiss guards were employed in order to keep the place independently and peaceful. Therefore any governmental forces could not enter this place. At the ground floor, Philippe Égalité rented 145 big stores in arcade, many boutiques and kiosks. There are 5 huge gambling clubs at the second floor and then upstairs there were many luxury apartments. We can also find a detached building for opera(Salle des Machines) built in 1770 in Palais-Royal. The proprietor opened all of the palace to the public, and it became the hottest commercial spot all over Paris. In this place, social or political speeches were rotated every evening in front of the audience over ten thousands, during June-July 1789. Passion for the Revolution was filled in Palais-Royal. On July 12th, eventually Camille Desmoulins jumped to the table in Café Foy and appealed to the audience for storming of the Bastille. People took the first step for the Great Revolution in Palais-Royal.

6세기 동아시아에서의 책봉호의 정치적 의미 ― 국제정세의 변동과 백제의 책봉호에 반영된 인식을 중심으로 ―

정동준 ( Jeong Dong-jun ) 수선사학회 2018 史林 Vol.0 No.66

This article compared and analyzed the general title or Sanguan(散官, prestige title) appointed for Baekje or other surrounding countries by Chinese southern dynasties, Northern Qi(北齊) and Sui(隋). Furthermoret, a appointer’s perception reflected in Ningdongdajiangjun(寧東大將軍, general title) and Dongqingzhoucishi(東靑州刺史, province governor) which are representative appointment titles, and the status of Baekje in the international order of East Asia were examined. A summary is as follows. In Chinese southern dynasties of 6th century, the number of appointment of surrounding countries decreased and hierarchizing between political organizations by the graded appointment of the general title diminished. As a result, the political use of the appointment title also decreased than the former period. Especially, appointment of western political organizations by Chinese dynasties and the political use of the appointment title decreased due to the depreciation in strategic value of western area because of Western Wei(西魏) and Northern Zhou(北周)‘s territory expansion. There was a small change in Baekje’s general title which had been practically fixed as Zhendongdajiangjun(鎭東大將軍, general title) during the 5th century. It was the degradation to Suidongjiangjun(綏東將軍, general title) in 524, and this appeared when Chinese southern dynasties appointed the lower general title than former period to surrounding countries. In the 6th century, Baekje was temporarily superior to Goguryeo on the general title unlike the 5th century when Baekje was inferior to Goguryeo throughout that century. It was the result of interaction of depreciating strategic value of Goguryeo and rising expectations for Baekje. In Northern Qi and Sui of 6th century, the number of appointment of surrounding countries were remarkably less than that of Chinese southern dynasties, and hierarchizing between political organizations by the graded appointment of the general title almost disappeared. This phenomenon means that the political use of the appointment title has disappeared. It was possible because Northern Qi was actually able to make appointment for only eastern political organizations due to the geographic situation surrounded by Northern Zhou(北周), Turk(突厥) and so on, and Sui could control surrounding countries not by the appointment but by the political power since Sui was closer to a unified empire from the establishment stage. The later half of the 6th century, when Northern Qi and Sui made appointment for surrounding countries, is inappropriate to compare the status in the international order between the Three kingdoms of ancient Korea(三國) by analyzing the general title or Sanguan appointed by Chinese dynasties. Ningdongdajiangjun which was appointed to King Muryeong(武寧王) was higher in rank than Ningdongjiangjun(寧東將軍, general title) appointed to king of Goguryeo in the same period. However, the reversal of the title disappeared by the appointment of King Seong(聖王) as Suidongjiangjun, which was lower in rank than Ningdongjiangjun. Dongqingzhoucishi was considered as the appointment title, as well as Dududongqingzhouzhugunshi (都督東靑州諸軍事, area commander-in-chief), which includes expectations of Northern Qi for the military support from Baekje. It is assumed that the appointment was made for Baekje because Northern Qi was not satisfied with the military support from Goguryeo and Silla which was accompanied by the appointment. The reason why Northern Qi had higher expectations in Baekje than Goguryeo and Silla is that they shared the same interests and needed each other.
