返本開新 : 從顔元的習行哲學看明末淸初的思想特点 근본으로 돌아가 새로운 것을 개척한다 Fronteering through Return to the Root

안병강 慶尙大學校 南冥學硏究所 2004 남명학연구 Vol.18 No.-

顔元은 중국 명말청초의 걸출한 사상가이자 교육가였다. 그는 야심찬 기백으로 2천여 년 동안의 학술 권위에 도전하고, 2천 년 동안 열지 못한 입을 열었고, 2천년 동안 대지 못한 붓을 대었다. 그는 漢學과 宋明理學을 맹렬하게 비판하고, 周公·孔子의 正學으로 되돌아갈 것을 강렬히 요구하였다. 그는 '復古'의 깃발을 내세워 유학의 새로운 형태에 대하여 탐구하였다. 그의 사상은 한 마디로 返本開新으로 특징지울 수 있다. 이런 사상을 근본으로 한 그의 사상적 특징을 좀더 구체적으로 살펴보면 다음과 같이 요약할 수 있다. 첫째, 명말청초의 사상적 특징은 천하의 일을 자신의 임무로 하는 유학자들이 사회적 책임의식을 강하게 전개한 점인데, 안원에게서 그런 의식이 뚜렷이 나타난다. 안원은 "성인의 책을 읽으면 세상을 바꾸는 사람이 되어야지, 세상에 따라 바뀌는 사람이 되어서는 안 된다."라고 하여, 적극적인 사회 개혁을 주창하였다. 이처럼 그의 사상에 있어 가장 중요한 특징 중 하나가 세상을 바꾸자는 사회개혁사상이다. 둘째, 그의 사상에는 깊은 반성과 주체적 자각이 자리하고 있다. 안원은 이론을 내세울 때는 옳고 그른 점만 따져보고 같고 다른 점은 따지지 않았다고 한다. 이는 그의 학술적 자각이다. 또 안원은 옳은 것이라면 비록 한두 사람의 견해일지라도 바꿀 수 없다고 하였으니, 이는 높은 학문적 주체의식이다. 이런 반성과 주체적 자각을 통해 안원은 송명이학은 물론 한학까지도 철저히 비판하였다. 셋째, 안원은 배워서 실제에 응용하는 것을 중시하여, 用을 본체로 삼고 用을 학문으로 삼았다. 그는 兵·農·錢·穀·水·火·工·虞를 體이면서 用으로 보아, 體와 用을 하나로 보았다. 그의 習行哲學은 이런 사상에 기반하고 있다. 이러한 그의 사상적 특징으로부터 명말청초 중국철학의 새로운 동향을 엿볼 수 있다. 그런데 그가 숭상하고 실행한 習行哲學은 外在的인 사회에서는 그 결과를 볼 수 없었고, 학문 안에서만 탐구할 수밖에 없었다. Ahn, Won(顔元) who lived in the period from late Myoung to early Choung dynasty(明末淸初) was not only an outstanding scholar but also an educator. He challenged the academic authority, and opened the closed mouth, and held the not to be raised pen for two millenium, with his ambitious spirit. He claimed the returning to the study of Jeong-hak(正學) while criticizing anger the Han-hak(漢學) and the Song-myoung-ri-hak(宋明理學). His ideology characterized to 'Returning to the Root & Renewing(反本開新)' in a word. The concrete features of this ideology of him are summarized as follows; First, the academic features of from late Myoung to early Choung dynasty represented that the scholars who regarded the matter of grave concern to the state as their duty developed the social duty consciousness, Aim-won shows the same tendency. He initiated the theory of active social revolution, with saying "A person who read the book of saint must be a revolutionist not to be a traitor." Like this way, the most important feature of his ideology is the social revolution. Second, it take root a deep reflection and active self-awareness in his ideology. People say that he inquired into right or wrong not into same or differ when suggesting a theory. This is the very ideological self-awareness. And he shows outstanding academic self-confidence while saying, "It can not be modified the truth although it derived from minority." Ahn, Won criticized thoroughly Han-hak(漢學) and Song-myoung-ri-hak(宋明理學) with these selt-reflection and self-awareness. Third, he paid attention to the practice which of the application of learning, and he made the Funtion(用) to his study way. Moreover, he regarded that the Funtion and the Thing(體) as same thing such as military(兵), agriculture(農,) finance(錢,) grain(穀), irrigation(水), fire (火), mechanics(工), nature(虞). His practical philosophy is based on this ideology. We can observe a new tendency of China in the period from late Myoung to early Choung dynasty from these ideological features. However, the practical philosophy which respected and practiced by him, it could not produced its result in real society and just be researched in the area of academy.

Picosecond Mid-Infrared 3.8 μm MgO:PPLN Optical Parametric Oscillator Laser with High Peak Power

Bing-Yan Chen,Yu-Heng Wang,Yong-Ji Yu,Guang-Yong Jin 한국광학회 2021 Current Optics and Photonics Vol.5 No.2

In this study, a compact, picosecond, mid-infrared 3.8 μm MgO:PPLN optical parametric oscillator(OPO) laser output with high peak power is realized using a master oscillator power amplifier (MOPA)1 μm solid-state laser seeded by a picosecond fiber laser as the pump source. The pump source was a 50MHz and 10 ps fiber seed source. After AOM pulse selection and two-stage solid-state amplification, a 1,064 nm laser output with a repetition frequency of 1–2 MHz, pulse width of 9.5 ps, and a maximum average power of 20 W was achieved. Furthermore, a compact short cavity with a unsynchronized pump is adopted through the design of an OPO cavity structure. When the injection pump power was 15 W and the repetition frequency was 1 MHz, the average output power of idler light was 1.19 W, and the corresponding peak power was 119 kW. The optical conversion efficiency was 7.93%. When the repetition frequency was increased to 2 MHz, the average output power of idler light was 1.63 W, the corresponding peak power was 81.5 kW, and the optical conversion efficiency was 10.87%. At the same time, the output wavelength was measured at 3,806 nm, and the beam quality was M X2 = 3.21 and M Y2 = 3.34.

Archaeal Communities in Mangrove Soil Characterized by 16S rRNA Gene Clones

Bing Yan,Kui Hong,Zi-Niu Yu 한국미생물학회 2006 The journal of microbiology Vol.44 No.5

An archaeal 16S rRNA gene library was constructed from mangrove soil. Phylogenetic analysis revealed archaea in mangrove soil including the Crenarchaeota (80.4%) and Euryarchaeota (19.6%) phyla. The archaeal community in mangrove soil appears to be a mixture of organisms found in a variety of environments with the majority being of marine origin.

The Use and Study of Time-Lapse Tools in Virtual Sound Field Design

Yan-bing Wang(왕얀빙) 한국컴퓨터정보학회 2017 韓國컴퓨터情報學會論文誌 Vol.22 No.7

In this paper, we propose a methodology of using time-lag, make it serve the sound field, in order to smoothen the music production and reduce conflicts. The importance of music production in today’s music industry chain is becoming more and more apparent. In the process of music production, the creators pay more attention to the design and adjustment of virtual sound field, especially the late mixing and production. In the process, as a commonly used tool for the adjustment of sound field, “time-lapse” plays a decisive role.

The Classification of Music Styles on the Basis of Spectral Contrast Features

Yan-bing Wang(왕얀빙) 한국컴퓨터정보학회 2017 韓國컴퓨터情報學會論文誌 Vol.22 No.1

In this paper, we propose that the contrast features of octave spectrum can be used to show spectral contrast features of some music clips. It shows the relative spectral distribution rather than average spectrum. From the experiment, it can be seen the method of spectral contrast features has a good performance in classification of music styles. Another comparative experiment shows that the method of spectral contrast features can better distinguish different music styles than the method of MFCC features that commonly used previously in the classification system of music styles.

The high dosage of earthworm (Eisenia andrei) extract decreases cell proliferation and neuroblast differentiation in the mouse hippocampal dentate gyrus

Bing Chun Yan,Ki-Yeon Yoo,Joon Ha Park,Choong Hyun Lee,Jung Hoon Choi,Moo-Ho Won 대한해부학회 2011 Anatomy & Cell Biology Vol.44 No.3

Earthworm extract has shown anticancer characteristics. In the present study, we examined the effect of chronic treatment with a high dose of earthworm (Eisenia andrei) extract (EE) on cell proliferation and neuroblast differentiation in the hippocampal dentate gyrus (DG) of 3-week-old mice using 5-bromo-2’-deoxyuridine (BrdU) and Ki-67 immunohistochemistry for cell proliferation and doublecortin (DCX) immunohistochemistry for neuroblast differentiation, respectively. BrdU-, Ki-67-, and DCX-immunoreactive cells were easily detected in the subgranular zone of the DG in vehicle (saline)-treated mice. However, BrdU-, Ki-67-, and DCX-immunoreactive cells in the 500 ㎎/㎏ EE-treated mice decreased distinctively compared to those in the vehicle-treated mice. In addition, brain-derived neurotrophic factor (BDNF) immunoreactivity and its protein level decreased markedly in the DG of the EE-treated group compared to those in the vehicle-treated group. These results indicate that chronic treatment with high dose EE decreased cell proliferation and neuroblast differentiation, and that BDNF immunoreactivity decreased in the DG of EE-treated mice.

Comparison of the immunoreactivity of Trx2/Prx3 redox system in the hippocampal CA1 region between the young and adult gerbil induced by transient cerebral ischemia.

Yan, Bing Chun,Park, Joon Ha,Ahn, Ji Hyeon,Lee, Young Joo,Lee, Tae Hun,Lee, Choong Hyun,Cho, Jun Hwi,Kim, Myong Jo,Kim, Tae Young,Kang, Il-Jun,Won, Moo-Ho Kluwer Academic/Plenum Publishers 2012 Neurochem Res Vol.37 No.5

<P>In the present study, we compared the immunoreactivities and levels of Trx/prx redox system, thioredoxin 2 (Trx2), thioredoxin reductase 2 (TrxR2) and peroxiredoxin 3 (Prx3), as well as neuronal death in the hippocampal CA1 region between the adult and young gerbil after 5 min of transient cerebral ischemia. At 4 days post-ischemia, pyramidal neurons (about 90%) in the adult stratum pyramidale of the CA1 region showed 'delayed neuronal death (DND)'; however, at this time point, few pyramidal neurons showed DND in the young stratum pyramidale. At 7 days post-ischemia, about 56% of pyramidal neurons showed DND in the young stratum pyramidale. The immunoreactivities of all the antioxidants in the young sham-group were similar to those in the adult sham-group. At 4 days post-ischemia, the immunoreactivity of TrxR2, not Trx2 and Prx3 in the adult ischemia-group was dramatically decreased in CA1 pyramidal neurons. At this time point, the immunoreactivities of all the antioxidants in the young ischemia-group were apparently increased compared to the adult ischemia-group. From 7 days pots-ischemia, non-pyramidal cells showed the immunoreactivities of all the antioxidants in the ischemic CA1 region; however, in the young ischemia-groups, the immunoreactivities were much lower than those in the adult ischemia-groups. In brief, our results showed that the immunoreactivities of Trx2, TrxR2 and Prx3 were dramatically increased in CA1 pyramidal neurons of the young ischemia-groups at 4 days post-ischemia compared to those in the adult ischemia-groups induced by transient cerebral ischemia.</P>
