笔者在曾经写过的一篇文章「用以修辞法接近于道德经圣人之定义」,得出了一些结论:所谓的圣人主要指大同社会的领导者-三皇五帝。孔子在论语中谈到作为领导人该具有些什么样的形象时,经常提到了君子:孔子在论语里提到君子一共有107次。因此,在这里我们有必要探讨一些问题:一,对孔子来说君子有着什么样的含义?二,孔子所追求的是什么样的社会,何必那么强调了君子?三,圣人与君子之间有何差别?笔者着眼于这几点,以论语的与君子有关的句子为主,要进行分析并试图得出些比较具体的结论。
병렬처리로 구현한 자기조직화 신경망을 이용한 정규혼합분포의 추정
안성만,이철희 한국지능정보시스템학회 2011 한국지능정보시스템학회 학술대회논문집 Vol.2011 No.12
본 연구에서는 자기조직화 신경망이 필요한 노드만을 가지고 최적화하여 정규혼합분포를 추정하는 모형(안성만, 2011)을 Java언어에서 제공하는 스레드(Thread)를 기반으로, 멀티코어컴퓨팅환경에서 병렬처리방식으로 구현하여 순차처리방식에 비해 짧은 연산시간으로 정규혼합모형의 추정이 가능함을 보이려고 한다. 안성만(2011)이 제안한 모형은 개념적으로는 병렬처리가 가능한 것으로 보이지만 실제 병렬처리로 구현하려면 혼합비율의 조건부 기대값을 매번 수정해야 하는 문제로 인하여 각 병렬처리 노드가 독립적으로 실행되지 못하는 문제가 있다. 이 문제를 고려하여 본 연구에서는 병렬처리 방법론을 제안하고 그 성능을 평가하였다. 병렬처리 방법론은 Java의 멀티스레드를 이용하여 구현되었으며, 모의실험을 통하여 제안한 모형이 기대한 결과를 얻음을 확인하였다.

This study was carried out to optimize microencapsulation conditions for Inonotus obliquus extract powder with mediumchain triacylglycerol (MCT) using response surface methodology (RSM), and to determine the possibility of adding encapsulated I. obliquus extract to milk toward improving the functionality of milk. and to investigate the effects of added encapsulated I. obliquus extract on the physicochemical and sensory properties of the product. The microencapsulation efficiency of I. obliquus extract powder was investigated with respect to three variables (ratios of core material to coating material,amounts of water added, and spray pressure) in RSM. The optimal conditions for microencapsulation of I. obliquus extract powder were obtained from the ratio of core material to coating material (2.92:10) and the amount of water added (0.5 mL);the spray pressure had an insignificant effect on the microencapsulation (p<0.05). Adding encapsulated I. obliquus extract into milk did not significantly affect either color (L, a and b values) or thiobarbituric acid (TBA) values. Sensory test revealed that there were significant improvements in brownish, herb flavor, and bitterness scores for encapsulated I. obliquus extract-added milk as compared with those for uncapsulated I. obliquus extract-added milk. Based on the data obtained from the present study, it is concluded that microcapsules of I. obliquus extract powder could be applicable to milk without remarkably adverse effects on physicochemical and sensory properties
Changing the sp2 Carbon Clusters in Graphene Oxide During Exfoliation
안성일 한국전기전자재료학회 2015 Transactions on Electrical and Electronic Material Vol.16 No.1
The change of the chemical structure of graphene oxide (GO) was investigated by periodical sampling of GO duringexfoliation by using a sonicator. A significant amount of GO was exfoliated during up to 10 hr of sonication. Ramanand Fourier transform infrared spectroscopy revealed a continuous increase of the G/D or C=C/C=O peak ratio ofGO, as the sonication time increases. The photoluminescence (PL) intensity of each GO sample also decreased asa function of the sonication time. PL excitation spectra with three major peaks indicate that the sizes of sp2 carbonclusters were enlarged by longer sonication. In addition, new excitation at around 300 nm proves the existence ofnewly developed small clusters of sp2 carbons as the sonication time increased.
