In this paper, the researcher investigated the standpoint of Lee EonJeok(李彦迪), also known as HoeJae(晦齋), with regard to interpretation of Daxue("大學"), through Daxuezhangjubuyi("大學章句補遺") and XuDaxuehuowen("續大學或問"). It is true that HoeJae accommodates a fairly large portion of interpretations made by Zhuzi, however, he strived to pass over Zhuzi's Daxuezhangju by attempting a new interpretation on the Gewuzhizhi(格物致知). The greatest reason that HoeJae couldn't admit Zhuzi's view was derived from the differences in interpretation of Gewuzhizhi. The differences between Zhuzi and HoeJae concerned with Gewuzhizhi is that, while Zhuzi perceived the objects thereof from the perspective of Li(理) of things(事物), HoeJae considered the root and branch, the beginning and end of the physical world(萬物) and also all events(萬事) as the subjects of Gewuzhizhi. Meanwhile, having the chapter, dubbed, 'Weyoubenmo'(物有本末), and the chapter, 'ZhiZhi'(知止) also as expositions of Gewuzhizhi, HoeJae was able to avoid such critiques as that he complemented or added new topics to the sutra. In addition, he could have clarified the stepwise elucidations of Sangangling(三綱領) and Batiaomu(八條目) edited and compiled by Zhuzi(朱子). And the issues in the chapter of Tingsong(聽訟) lies on the extended line of theory of Gewuzhizhi. In the end, it suggests that the differences between Zhuzi and HoeJae are arisen from the discrepancies of interpretation on Gewuzhizhi. HoeJae proposed his ideology concerned with Zhizhizhuyi(至治主義) through his book, XuDaxuehuowen, and he stressed that Ren(仁) must be foundation in order to Pingtianxia(平天下). Furthermore, HoeJae emphasized that Ren which is the founding virtue in order for Pingtianxia must be begun with such very basic behavioral practices, known as, Xiao(孝), Ti(弟), and Ci(慈), and that such desirable states would be accomplished through relationships with others, not merely through self-endeavors or by self-ego.

일일 최대 석탄처리 용략이 3톤인 건식 석탄가스화기를 사용하여 가스화에 미치는 주요 변수들중 산화제내 산소농도와 증기 주입량을 변경시켜 가스화성능을 조사하였고, IGCC용 대성석탄을 선정하는 입장에서의 주요 인자 및 고온고압 조건에서의 가스화기 운전상 특성과 문제점을 파악하여 운전상 문제에 대한 대책을 제시하였다. 사용한 석탄은 유연탄인 중국 대동탄과 아영청탄인 미국 알라스카의 유시벨리탄에었는데, 두 탄중 모두 건식 가스화기의 운전상에는 문제가 없었다. 가스화를 위한 산소의 농도는 90%까지 그리고 석탄시료 무게 대비 증가량 10∼12%까지는 가스화의 온도 유지와 가스조성 측면에서 무리 없이 적용할 수 있다고 판단되었다. 이들 가스화 시험을 통하여 생성된 슬랙은 가스화기 슬랙탭의 조업 온도와 대상석탄 회재의 용융특성에 따라 침상 또는 알갱이 형태로 배출되었으며, 슬랙으로부터 중금속 성분이 유출되는지를 분석해 본 결과 침출수에 의한 2차 오염은 없는 것으로 확인하였다. IGCC용 석탄을 선정하는 석탄특성에서는 미분탄의 수분함량, 회재함량, 회재용융온도, 발열량 측면에서 검토하였는데, 건식가스화기의 경우 미분탄의 표면수분의 제거가 중요하고 회재의 함량과 회재의 용융온도를 같이 고려하여 적정한 시료 석탄이 선정되어야 한다는 결론을 얻었다. 가스화기 운전측면에서는 여러 기계적인 문제점들이 발견되었는데 시료공급노즐의 막힘문제, 역화문제, 고온가스 누출문제, 추운 겨울 운전시 오링(O-ring)문제 등에 대한 논의와 대책을 제시하였다.

본 연구에서는 석탄회재를 이용하여 메조 포러스 실리카를 제조하였다. 제조된 메조포러스 실리카는 X-선 회절패턴, TEM, FT-IR을 통하여, HMS특성과 동일하게 나타났으며 결과적으로 메조 포러스 실리카 물성에 가장 영향을 나타내는 것은 반응온도, 시간이며 석탄 회재의 규소용출은 소성온도가 낮을수록 증가하며 규소원에 따라 각기 다른 특성을 나타냄을 합성된 메조포러스 실리카의 물리화학적 특성으로 부터 알 수 있었다.

This thesis is about Chungyongkugyongyonui(中庸九經衍義) by HoiJae Lee Eon Jeok (1491~1553). As many know, he was one of the philosophers representing the 16th century who played a great role in making the Zhūzǐ's Neo-Confucianism settle down in Joseon society through the dispute on TaeGeuk (太極) against Cho Han Bo (?~?). He was also the scholar who firmly established the theoretical system of the Idea for Proper Governance (至治主義). The Supplementary Explanation to the Chapters and Phrases of the Great Studies (大學章句補遺) and the Transcript of Nine Annotations on the Middle Way (中庸九經衍義) were written to argue his thoughts of the Idea for Proper Governance shown in the Great Studies (大學) and the Middle Way (中庸). He said that the Great Studies was more specific in the clauses for the justice of training oneself while the Middle Way more detail in the clauses for the justice of governor. That is, he thought that those books were in the relation of the in-and-outside, so that he argued that kings should take both justices of such for governance. Especially the Transcript of Nine Annotations on the Middle Way was written by following the way of the Annotation Transcript of the Great Studies (大學衍義) by Jin Deok Su (眞德秀), a scholar of Song Dynasty and the Supplementary Explanation to the Annotation Transcript of the Great Studies (大學衍義補) in order to make the King MyeongJong of that period realize the Proper Governance of the Two Great Emperors and Three Great Kings of Ancient China, which greatly influenced the Ten Figures of the Studies for the Great Man (聖學十圖) by ToiGye Lee Hwang and the Abstract of the Studies for the Great Man (聖學輯要) by YulGok Lee Yi.

1980년대 중반이후 화력발전소용으로 순환유동층 연소로(Circulating fluidized bed combustor : CFBC)가 많이 건설되고 있다. 이는 기존의 고정층 연소로보다 효율면에서 좋고, 차지하는 부피는 훨씬 적기 때문이다. 순환유동층의 층물질로 사용되는 모래, 석탄회, 석회석 등은 순환하는 입도, 비산유출되는 회재(fly ash)와 하부로 배출되는 회재(bottom ash)로 나누어진다. 주입되는 석탄 및 석회석의 입도는 입자-입자, 입자-연소로의 마모(attrition), 입자의 깨짐(fragmentation), 입자의 축소(shrinking) 등에 의해서 변화하게 된다.(중략)

폐기물 소각시 발생되는 각종 유해가스 및 비산회재(fly ash)는 후처리 설비에 의해 배출허용기준치 이하로 처리된 후 대기 중으로 방출되도록 환경 규제되고 있다. 그러나 포집된 비산회재(fly ash) 및 노하부 배출재(bottom ash) 내에는 미 연소된 상태로 배출된 유해성 유기물질(다이옥신, 퓨란류 등)과 중금속 성분이 함유되어 있어 이들 소각잔류물(incineration residues)을 안정화나 무해화 처리 없이 단순 매립할 경우 강우에 의해 소각잔류물 내의 유해성분이 침출됨에 따라 토양이나 지하수 등에 2차 환경오염을 일으키게 된다.

In the reactor following the American standard test method (ASTM) D5757-95 and lab-scale fluidized bed combustor, the attrition characteristics of sand and ash of Korean anthracite were investigated. The attrition characteristics, such as particle size distribution of fly ash, attrition rate, and attrition ratio etc, were studied with variation of gas velocities. The particle attrition of ash was more active than sand which was generally used as a fluidized material and also the attrition index of ash taken by ASTM D5757-95 was 5 times higher than that of sand. The formation of fine particles continuously occurred due to particle attrition with increasing gas velocities. The following equation has been suggested for attrition rate of ash. $$\frac{dW}{dt}=-3.18{\times}10^{-7}(U-U_{mf})W$$.

The utilization of fly-ash containing high levels of the unburned carbon was investigated. In this study adsorbents were manufactured from fly-ash ad a raw material and the manufactured adsorbents were applied to the waste-water treatment including heavy metals. Varying the anthracite(Jangsung coal) content, three types of pellet were made. The carbon content of pellet increased appreciably upon the addition of anthracite. After carbonization and activation using the pellets, adsorbents showed following characteristics; the range of hardness was between 85% and 96%, iodine number was from 100 mg/g to 300 mg/g. In proportion to the anthracite addition, hardness and iodine number increased. Through the adsorption experiments of heavy metals, removal efficiencies of Pb and Cr by manufactured adsorbents were over 90%. In case of fly-ash, removal efficiencies of Pb and Cr were 31.5% and 5.6% respectively. The reason why removal capacities of manufactured adsorbents were higher than fly-ash was postulated that adsorption capability was improved by unburned carbon and $SiO_2$ which included in fly-ash during steam activation.
