Qingping Luo,Chonghua Pei,Guixiang Liu,Yongjun Ma,Zhaoqian Li 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2015 NANO Vol.10 No.3

Cyclotrimethylenetrinitramine (RDX) is an energetic material (EM) from the class of cyclic nitroamine explosive widely used in military applications because of its excellent integral properties. Using bacterial cellulose (BC) gelatin with a three-dimensional network as a matrix, N,Ndimethyllformamide (DMF) as the solvent of RDX, the RDX nanostructured explosives were prepared through the solvent/nonsolvent method. It was found that the solvent had a great impact on the crystallization of RDX in the solution and the RDX content in the nanostructured explosive. The RDX particles in the nanostructured explosives smoothly coated to the nanofibers of BC gelatin network at high RDX concentrations, and the granularity distributions of RDX in the nanostructured explosives were very uniform in the range of 30–50 nm. The average contents of the RDX in the nanostructured explosives are greater than 83 wt.% when the RDX concentrations of the soaked solutions are greater than 0.20 g/mL. The average content is approximately 91 wt.% when the RDX concentration is 0.30 g/mL. The decomposition temperatures of the RDX nanostructured explosives were found to decrease approximately to 20 C and their mechanical sensitivities decreased greatly compared to that of raw micro-size RDX. It opens a useful way to prepare nanostructured explosives with high energy and low mechanical sensitivity.

Co spin state and magnetic structure in GdBaCo2O5þx and Fe doped compounds: A first principles study

Qingping Zhang,Xiusheng Wu,Eerjun Kan 한국물리학회 2016 Current Applied Physics Vol.16 No.9

GdBaCo2O5.5 exhibits impressive application potentials on giant magnetic resistance materials and solid oxide fuel cell cathodes, owing to its unique electrical and magnetic properties. In this article, stable magnetic-order structures of Co in GdBaCo2O5.5, Fe doped compounds, and GdBaCo2O5.25 with additional oxygen vacancy deficients, are investigated based on first principles calculations. Comparisons with reported experiments are also presented. It turns out that G type antiferromagnetic ordering is the most stable under ground state, and Co is high-spin state, which matches the observations of neutron diffraction and XAS spectrum. Calculated results show that the stability of ferromagnetic phase under low temperature will be enhanced by the introduction of Fe dopant, which is supported by the reported experiment. Moreover, additional oxygen vacancies caused by the valence alternation of Co ions are discussed. The magnetic moments of several Co cations closed to the additional vacancy are reduced. Besides, oxygen ions could be divided into 3 layers based on their stabilities. Oxygen vacancy formation energies within two layers are much lower, which facilitate the oxygen ion transfer along these layers. This result also fits the conclusion of reported molecular dynamic simulation well.

論"親親相隱"?曲正義感的負面效應

류청평 ( Qingping Liu ) (사)율곡연구원(구 사단법인 율곡학회) 2015 율곡학연구 Vol.31 No.-

``자식이 부모의 허물을 감추고(子爲父隱)``, ``몰래 없고 도망친다(竊負而逃)``라는 유명한 사례 중에 공자와 맹자는 명확하게 다음과 같이 주장하였다. 아버지가 ``양을 훔치고(攘羊)``, ``살인(殺人)``을 저지르는 등의 사람을 등치고 해하는 범죄 행위에 종사하더라도 아들은 ``효자``로서 반드시 유가에서 견지해야 하는 ``혈친정리(血親情理)`` 정신을 따라야 한다. 바로 아버지의 범죄 행위를 감추려 노력하거나 내지는 아버지의 도피를 도울 방법을 찾아 아버지가 그 범죄로 인해 도덕적 견책과 법률적 징벌을 받지 않도록 하는 것이다. 깊이 분석해보면, 이 ``친친상은``의 관념은 공자와 맹자 당시에 이미 자각적으로 인정했던 "진실로 인에 뜻을 두었다면, 악함이 없다"(苟志于仁矣, 無惡也) "죄없는 자를 죽이는 것은 어질지 못함이며 자기가 소유하지 않은 것을 취함은 의가 아니다"하는 도덕적 최저선(最低線)과 충돌하고, 사람들로 하여금 지고무상한 혈연친정(血緣親情)을 유지하고 친속의 정당치 않은 사리사욕을 보호하도록 부추겨왔다. ``남을 해치고 친속을 이롭게(損人利親)`` 하는 것을 부끄러워하지 않는 것은 유가의 특수성인 ``효제(孝悌)``에 의존해 보편성인 ``인의``를 부정하는 심각한 모순을 드러내는 것이다. 바로 이러한 이유로 인해, 공맹 유학의 ``친친상은``의 관념과 현대 서양사회의 ``친속간 용인`` ``사적 권리 용인``, ``침묵권``과 관련된 법률 규정과 목적과 실질에서 큰 차이를 보인다. 또한 후자처럼 기본적으로 "사람을 등치거나 해치지 않고 인권을 존중한다"라는 정의의 최저선에 부합하지 않을 뿐만 아니라, 공맹유학 윤리사상의 내적 모순을 폭로하고 있다. 이는 한편으로는 고상하고 순결한 ``인의도덕``을 자각적으로 창도하겠다고 자임하고 또 그로 인해 현대사회에서 추종하는 ``인권 존중``을 세상에 펼치겠다는 가치와 근본적으로 일치하는 적극적 요소를 포함하고 있다. 다른 한편으로 인간이라면 응당 소위 ``천리 인정``에 기초하여 ``친친상은``과 같은 피해자의 권익을 침해하고 또 동시에 ``인의``라는 표준을 위반하는 부도덕적 행위를 하도록 주장한다. 2000여 년 넘게 공맹유학의 이러한 관념은 중국 사회와 중국인의 심리와 도덕 전통에 엄중한 부작용을 낳았으며, 특히 사람들은 수천년 동안 공동 생활 속에서 형성된 ``사람을 등치거나 해치지 않는 정의감(양심)``을 왜곡하였다. 그래서 웅십력은 ``정의감 결핍`` 현상을 명확하게 지적했으며, 지금도 여전히 어느 정도 차이는 있으나 서로 끌어주는 관계나 뒷거래, 외척 관계, 태자당, 가족부패, 사사로운 정에 얽매여 법을 어김, 개인 파벌을 만듦, 신뢰를 지키지 않음, 위증과 거짓말을 늘어놓음, 인권을 중시하지 않음, 법치를 경시함 등 부도덕한 행위의 범람과 유행을 용인하게 했다. 이를 통해 우리는 유가 자신이 적극적으로 인정하는 ``인의``의 표준을 빌려 유가가 견지하는 ``혈친정리`` 정신을 엄중히 비판할 수 있으며, 공맹이 창도한 ``친친상은`` 관념을 근본적으로 부정할 수 있고, 어떤 상황 하에서도 ``인권 존중``을 긍정하는 정의의 최저선이 신성불가침한 영역으로 유지되도록 할 수 있다. 또한 "사람을 등치거나 해치지 않는 것"이 고금에 유전되고 세상이 공인할 뿐만 아니라, 유가의 ``인의`` 표준에 내재한 ``정의감``이 다시금 사회에 주도적 지위를 점하게 할 수 있다. In the two famous cases of Lunyu (the Analects) 13:18 and Mengzi 7A35, both Kongzi and Mengzi definitely hold that, even the filial son has known his father`s criminal offences such as stealing a sheep and murdering an innocent, he should still try his best to conceal his father`s crime and even take his father to flee in order to prevent his father from moral condemnation and lawful punishment according to the Confucian basic spirit of "consanguineous emotionale". It may be argued through a close analysis that this typical Confucian idea seriously violates the bottom line of "humaneness and justice (renyi)" clearly set up by Kongzi and Mengzi themselves, and encourages people to do substantive harm to their fellow humans merely for the sake of kinship love as well as the selfish interests of their relatives. In such an in-depth ethical paradox, this idea is also sharply different from those legal provisions of contemporary Western society about family concealment and right to privacy or to silence, and shows the in-depth paradox of Confucianism as a moral doctrine in distorting people`s common sense of justice as "no harm to fellow humans". In reality, this distortion has brought about a lot of serious negative effects in Chinese society till now, so that we should re-affirm the ultimate significance of the sense of justice as "no harm to fellow humans" through the profound criticisms of the Confucian spirit of "consanguineous emotionale" as well as its idea of mutual concealment between relatives.

황간(黃榦)의 『논어』 해석

덩칭핑(Qingping Deng),왕샤오전(Xiaozhen Wang) 한국외국어대학교 철학문화연구소 2023 철학과 문화 Vol.49 No.-

『논어』에 대한 주자의 저술들은 주자학파 학생들에게는 매우 중요한 교재 중 하나였다. 황간은 주자 문하의 가장 뛰어난 제자로서, 일찍부터 『논어』에 관한 주자의 저술 작업에 참여하였다. 황간은 주자의 『논어』 해석을 확장하고 천명하고 재해석하는 일을 매우 중시하였고, 그 내용은 그의 논어학을 구성하는 기본적인 내용이 되었다. 거기에는 다음 세 가지 중요한 특징이 있다. 첫째, 『논어』의 첫 장과 마지막 장에 대해 새로운 이해를 제시하였다는 점이다. 둘째, 주자의 『논어집주』를 세밀하게 분석하고 설명하였다는 점이다. 셋째, 『논어집주』와 『논어혹문』 사이에서 발견되는 주자의 상이한 화법을 소통시켰다는 점이다. 넷째, 『논어집주』에 대해 의문점을 제기하고 보충 설명했다는 점이다. 황간의 『논어』에 대한 독특한 해석은 그 의의가 매우 중요하며 주자학파의 논어학을 크게 발전시켰다. In the minds of all disciples, Zhu Xi (朱熹)'s interpretation of the Analects of Confucius is one of the most valued classics. As the most important disciple of Zhu Xi, Huang Gan (黄榦) participated in Zhu Xi's work on the Analects of Confucius. He placed great emphasis on extending, developing, and reinterpreting Zhu Xi's works on the Analects of Confucius, which constituted the basic content of Huang Gan's study of the Analects of Confucius. Among them, the more unique ones include: first, proposing a new understanding of the first and last chapters of the Analects of Confucius; second, meticulously interpreting “Ji Zhu” (集注); third, clarifying the different views between “Ji Zhu” (集注) and “Huo Wen” (或问) ; fourth, questioning and supplementing “Ji Zhu” (集注). Huang Gan's unique interpretation of the Analects of Confucius greatly enriched and developed the Zhu Xi School's studies on the Analects of Confucius. 朱子诠释《论语》的著作是其门人学习过程当中最为重要的文本之一。作为朱熹最重要的弟子,黄榦曾参与朱子有关《论语》著述的工作,他非常注重对朱熹《论语》著作进行引申、发挥和再诠释,这些内容构成黄榦《论语》学的基本内容。其中较为独特的内容包括:一、对《论语》首末章提出新理解,二、细致疏解《集注》,三、疏通《集注》与《或问》之间的不同说法,四、对《集注》提出质疑与补充。黄榦对《论语》的独特诠释极大丰富和发展了朱子学派的《论语》学。

묵자학설의 사상사적

유청평 ( Liu Qingping ) 영산대학교 동양문화연구원 2017 동양문화연구 Vol.26 No.-

묵가의 학설은 이미 일찍이 “현학”(顯學)의 지위를 잃었지만, 백가쟁명 시기의 다른 수많은 사조처럼 그렇게 흔적도 없이 사라지지 않고, 중국사상사에 있어서 매우 견고한 존재로 유지될 수 있었는데, 그 관건적 원인은 이천여 년 전의 묵자가 제기했던 “귀의”(貴義)를 저선으로 하는 일련의 완강한 생명력을 가지고 있기 때문이며, 심지어 오늘날 우리에게 계도적 의의를 주는 창조적 이념을 가지고 있을 뿐만 아니라, 특히 수많은 유가의 대표 인물들도 부득이하게 긍정적이었거나 부정적이었던 두 측면에 정면으로 도전하는 것으로써 유가의 혈연주의가 주장했던 “남을 헤치고 집안을 이롭게 한다”는 불의의 폐단을 지적하고 있기 때문이다. Although Mohism has lost its position as one of the “famous schools” for a very long time, it has not totally disappeared like many other schools of thought in the pre-Qin period, but could still maintain its strong and undeterred existence in the Chinese history of ideas. The key reason for it is that Mozi as a creative thinker already put forward quite a few original and profound ideas based on the bottom line of “valuing justice” two thousand years ago, which have not only revealed the fatal unjust defects of Confucian consanguinitism, but also are of abundant significances of enlightenment for us even today. As a result, many Confucian masters have had to be seriously confronted with the Mohist challenges from both the positive and negative perspectives.

Hypoglycemic Effects of Ganoderma lucidum Polysaccharides in Type 2 Diabetic Mice

Chun Xiao,Qingping Wu,Xiao-Bing Yang,Wen Cai,Jian-Bin Tan,Jumei Zhang 대한약학회 2012 Archives of Pharmacal Research Vol.35 No.10

Our aims were to investigate the hypoglycemic effects and mechanisms of action of Ganoderma lucidum polysaccharides (GLPs) administered for 7 days in type 2 diabetic mice. The mice were randomly divided into four groups (8 mice/group): normal control group, diabetic control group, low-dose GLP-treated diabetic group (50 mg/kg/d), and high-dose GLP-treated diabetic group (100 mg/kg/d). Diabetes was induced by streptozotocin injection and high-fat dietary feeding. At the end of the study, fasting serum glucose, insulin, body weight (BW) and epididymal white adipose tissue weight were measured. The hepatic mRNA levels of glycogen phosphorylase (GP), fructose-1,6-bisphosphatase (FBPase), phosphoenolpyruvate carboxykinase (PEPCK) and glucose-6-phosphatase (G6Pase) genes were determined by real-time polymerase chain reaction. Both doses of GLPs significantly decreased fasting serum glucose, insulin and epididymal fat/BW ratio compared with the diabetic control group (p < 0.05). The hepatic mRNA levels of GP, FBPase, PEPCK and G6Pase were significantly lower in both GLP-treated groups compared with the diabetic control group. Taken together, GLPs significantly decrease fasting serum glucose levels in type 2 diabetic mice in a dose-dependent manner. The decreases in fasting serum glucose levels may be associated with decreased mRNA expression levels of several key enzymes involved in gluconeogenesis and/or glycogenolysis.

Real-time PCR Targeting OmpA Gene for Detection of Cronobacter spp. in Powdered Infant Formula

Xiaohui Dong,Qingping Wu,Kui Wu,Jumei Zhang 한국식품과학회 2013 Food Science and Biotechnology Vol.22 No.2

Cronobacter spp. (formerly Enterobacter sakazakii), a pathogen commonly found in powdered infant formula (PIF), is a rare cause of invasive infection with a high mortality rate in neonates. In the present study, a realtime PCR assay was conducted to identify the pathogens in PIF using a TaqMan probe targeting the outer membrane protein A gene (ompA) of Cronobacter spp. The specificity of the PCR assay was tested against 25 strains of Cronobacter spp. and 38 non-Cronobacter bacterial species. The detection limits of this method are 1.0×102 copy/μL in standard plasmid, 1.1 CFU/100 g in PIF through 38 h of enrichment,and 2.8×102 CFU/mL in phosphate-buffered saline (pH 7.0). Based on the detection limits, real-time PCR is more sensitive than simplex and duplex PCR. These methods were successfully applied to actual samples, indicating that this real-time PCR assay can be used for the detection of Cronobacter spp. in PIF.
