공자(孔子)의 교학(敎學)을 근본으로 한 유학은 인도(人道)를 중시하는 인간학이다. 유학사상사의 흐름 속에는 객관적 현실에 대한 관심과 인간의 내면적 성찰이라는 양면성이 적절히 조화를 이루어 구현되어지기도 하였지만, 그 시대가 처한 제 조건에 따라 이 양자 가운데 어느 일면에 비중을 두는 경향도 뚜렷하였다. 본 논문에서는 유학의 역사인식이크게 양면적으로 전개되고 있다는 점에 주목하여 그 역사인식의 이중적 전개과정을 살펴보고 현대적 시사점을 받고자 한다. 시대상황에 따라 도덕주의적 입장에서 주체성의 확립으로 문제를 해결하기를 시도할 수도 있고, 현실주의적 입장에서 제도와 법제를 개혁하여 문제를 해결할 수도 있다. 여기서 도덕주의가 원칙론 적이요 온건한 방법이라면, 현실주의는 실무론 적이요 실용적 방법이라 볼 수 있는데, 두 가지 방법이 적절하게 시의(時宜)를 얻어야 효율적일 수 있다고하겠다. Confucius` Confucianism based on study of teaching and learning is the study of humanity that values humanism. The ambivalence made of caring of the real world and being enlightened internally was realized with good balance on the flow of ideology history in Confucianism. Depending on general condition of the age, however, some age focused more on a certain side of such ambivalence while some other age on the other side. In this study, therefore, I look into such ambivalent development of recognition of history to get ideas for the modern society by paying attention to the point that the recognition of history has been being developed ambivalently in Confucianism. Social issues will be handled for solution by establishment of subjectivity in the sense of moralism in some ages while such issues will be solved by reform of system and law in some other ages. That is, realism is thought to be a practical and usage-focused way while moralism to be a principle based gentle way. It is, thus, thought that both ways of such shall be used properly on time in order for efficiency.

RDF 데이터가 급속히 증가함에 따라 RDF데이터로부터 정보를 효율적으로 추출하는 기술의 중요성도 점차 커지고 있다. RDF데이터 질의를 위해 가장 많이 사용하는 질의언어인 SPARQL은 문법이 간단하고 그래프 패턴을 손쉽게 질의로 표현할 수 있는 장점이 있다. 그러나 사용자가 적절한 SPARQL을 작성하려면 데이터 셋에 대한 온톨로지 구조와 용어를 사전에 파악해야 한다. 이 연구에서는 데이터 셋으로부터 사전에 추출된 스키마정보를 이용한 그래프 질의 생성 및 처리방법을 제안한다. 제안된 방법에서 사용자는 RDF 데이터 셋에 대한 온톨로지 구조 사전파악 없이 화면상에서 동적으로 질의를 작성하여 정보를 조회할 수 있다. 사용자가 생성한 질의는 관계형데이터베이스에 저장된 트리플 데이터에 대해 그래프 탐색을 수행할 때 탐색공간 제약조건으로 활용된다. LUBM(10,0) 데이터 셋에 대하여 LUBM 질의 2, 8, 9번을 이용하여 질의 처리 성능과 완전성을 확인하였다. With the rapidly growing amount of information represented in RDF format, efficient querying of RDF graph has become a fundamental challenge. SPARQL is one of the most widely used query languages for retrieving information from RDF dataset. SPARQL is not only simple in its syntax but also powerful in representation of graph pattern queries. However, users need to make a lot of efforts to understand the ontology schema of a dataset in order to compose a relevant SPARQL query. In this paper, we propose a graph query formulation and processing scheme based on ontology schema information which can be obtained by summarizing RDF graph. In the context of the proposed querying scheme, a user can interactively formulate the graph queries on the graphic user interface without making efforts to understand the ontology schema and even without learning SPARQL syntax. The graph query formulated by a user is transformed into a set of class paths, which are stored in a relational database and used as the constraint for search space reduction when the relational database executes the graph search operation. By executing the LUBM query 2, 8, and 9 over LUBM (10,0), it is shown that the proposed querying scheme returns the complete result set.

The important drawback of epoxy electrodeposition(ED) coatings is the lack of the weathering resistance caused by the structure of bisphenol A. To improve this yellowing phenomena, acryl ED coatings have been developed. Compared with the epoxy ED coatings, however, acryl ED coatings are relatively weak in the corrosion resistance and mechanical properties. The purpose of this study is complemented their drawbacks by mixing epoxy and acryl ED paints. The salt spray, accelerated weathering test(QUV) and cupping, bending, impact test were employed to investigate the corrosion resistance, weathering resistance, and mechanical properties of ED coatings. When the ratio of acryl to epoxy resin of ED coating is 0.33, the weathering resistances are appropriately improved in condition maintaining the corrosion resistance. It was shown that the weathering resistance for epoxy ED coating was adjusted by optimally mixing acryl ED paint.

최근 인터넷을 통한 네트워크 응용들의 확산은 unicast에서 multicast로 넓혀가고 있는 추세이다. 그러나 공개키 쌍을 사용하는 PKI 키 관리 및 인증기법에 반해 그룹 키 관리 및 인증기법에 대한 연구는 아직 미비한 상태이다. 따라서 본 논문에서는 동일한 보안등급을 갖는 다중 사용자들이 보다 안전하게 키를 공유하고 인증할 수 있도록 하는 그룹 키 분산 기법에서, 즉, 그룹 키를 관리함에 있어서 필요한 정보보호에 대한 고찰 및 그룹 키 관리에서의 주요 처리인 join/leave 함수 처리, 다양한 그룹 키 분산 기법에 관하여 연구하고 보다 안전한 키 관리 및 객체가 갖는 장점들을 포함하는 안전한 그룹 키 분산기법에 관하여 논하도록 한다.

본 연구에서는 폴리우레탄을 위한 친환경 폴리올 합성을 위하여 피마자유 기반의 폴리올을 합성하였다. 피마자유의 2차 알콜에 다른 촉매 없이 무수말레산을 이용하여 카르복실기를 도입하고, 이를 1차 알콜로 전환하기 위하여 아미노알콜(H₂N-R-OH) 유도체를 반응시켜 친환경 폴리올을 제조하였다. 다양한 비율의 피마자유와 무수말레산의 반응이 시험 되었으며, 전체 반응은 상대적으로 낮은 공정온도와 무촉매 반응을 기반으로 수행되었다. 긴 곁가지가 도입되어 유동성을 가지고 있는 피마자유 기반의 천연폴리올이 기존의 합성폴리올과 가장 우수한 상용성을 나타내었다. We investigate new polyols based on castor oil for polyurethane. In order to introduce primary alcohol groups, which exhibit higher reactivity with isocyanate than secondary alcohol groups, the secondary alcohol groups on castor oil were modified with maleic anhydride and aminoalcohol derivatives (H₂N-R-OH). The reactions with various molar ratio of castor oil and maleic anhydride were done at relatively low reaction temperature in the absence of catalyst. The polyols based on castor oil with flexible side-chains exhibit better miscibility with conventional synthetic polyols.

조선후기 안동 상층 향리(鄕吏)의 향직계승(鄕職繼承)과 존재양상

정성학 ( Sung Hak Jung ) 서울대학교 국사학과 2014 韓國史論 Vol.60 No.-

This thesis focuses on the succession of hyangjik (鄕職) and the way how it existed Angdong (安東) Hyangli (鄕吏) with the list of the ex-officers (先生案), Jokbo(族譜), Land register (土地調사簿) in the late Choson Dynasty. Andong hyangli monopolized kamyongli (監營吏) which have the most powerful job in hyanjik. The member of Andong Kwon(安東 權), and Andong Kim (安東 金) monopolized upper hyangjik, then only few lineage could turned out upper hyangjik. It happened because commonly lineal family members inherited hyangjik. The method of heritage caused succession and fail of hyangjik even in the lineage which monopolized upper hyangjik. It occurred the weakening of the tribalism among hyangli families. There was competition for hyangjik with other city and district. However, since only few counties and lineages monopolized the upper hyangjik in 18 and 19th, the competition in the lineages or brothers became more important. This phenomenon was totally different with yangban(兩班)`s competing system such as kwago(科擧). The bond between the lineages, which had chances to be hyangli, and others, which did not, was hardly existed. In addition, some hyangli descendants who wanted to be sajok(士族) left the area where their ancestor lived for long time. The residence type and the aspect of using hangryol (行列) have proved their weak tribalism. In sum, hyangli had weaker family bond than yangban. Therefore, hyangli did not supported for their poor same race. Polarization of land possession was the result of differentization.
