So far there have been intermittently quantitative and syntactic analyses of the past elementary mathematics curriculums to comprehend elementary mathematics education in Korea. However, we think we also need qualitative and semantic analyses to comprehend and examine the past elementary mathematics curriculums exactly and so to look out on our future elementary mathematics education. Generally, school mathematics curriculum reflects both the philosophical aspects of mathematics itself that form the background of the philosophy of mathematics education and the sociological aspects in real mathematics class that could be the output of the curriculum. With this view, the logic of the social constructivism can be an appropriate way that leads mathematical philosophical analysis and sociological analysis in mathematics education. With this kind of method of analysis we got the results that: the past Korean elementary mathematics curriculums mainly have the tendency from the ideology of the progressive educator(the 1st) to of the technological pragmatist(the 2nd), from that of the old humanist(the 3rd and 4th) to the progressive educator(the 5th and 6th) again, and lastly that of social constructivism(the 7th).

Although BIBFRAME is recognized as a new bibliographic standard that can replace the existing MARC structure, the vastness of the descriptive items shows many limitations to be applied in library communities. Thus this study proposed separating the descriptive levels of BIBFRAME as a way to enhance the applicability of BIBFRAME. The descriptive level of BIBFRAME was divided into three stages: core, standard, and detailed levels based on the bibliographic area of ISBD 2011. This separation was semantically implemented using RDF/RDFS syntax. The levels of description in BIBFRAME was defined as Class Granularity and Class Element, and the Property Relation was defined for the linkage between the Classes defined and the BIBFRAME. By applying this syntactic structure, the relationships between the BIBFRAME descriptive items separated by each descriptive level could be linked with each other. This approach is expected to ensure applicability in the creation and sharing of bibliographic data using BIBFRAME.

Korean is free of omission of sentence elements and modifying scope, so managing it on morphological analyzer is better than parser. In this paper, we propose functional expansion methods of the morphological analyzer to ease the burden of parsing. This method is a longest phrase matching method. When the series of several morpheme have one syntax category by processing of Unknown-words, Compound verbs, Compound nouns, Numbers and Symbols, our method combines them into a syntactic unit. And then, it is to treat by giving them a semantic features as syntax unit. The proposed morphological analysis method removes unnecessary morphological ambiguities and deceases results of morphological analysis, so improves accuracy of tagger and parser. By empirical results, we found that our method deceases 73.4% of Parsing tree and 52.4% of parsing time on average.

일반적인 어휘망이 의미 관계에 의한 연결 구조를 중심으로 연구 개발된 것과는 달리, U-WIN은 의미관계를 비롯하여 개념 관계, 형태 관계, 구문 관계 등과 같이 의미 관계의 범위를 확장한 어휘 관계를 적용하여 구축하고 있다. 본 연구에서는 U-WIN의 어휘 관계 중의 하나인 구문관계를 자동으로 구축하는 방법을 제시하고자 한다. 먼저, 용언의 용례에서 문형정보를 기준으로 구문관계를 형성할 수 있는 후보명사를 추출하였으며, 추출한 후보명사는 용언의 세분화된 의미별로 정확하고 다양하게 추출할 수 있었다. 그러나 U-WIN은 다의어의 뜻풀이 하나하나를 개별적인 어휘로 구분하여 구축하였으므로, 어휘 간의 구문관계를 설정하기 위해서는 후보명사의 여러 의미 중에서 하나의 의미로 결정해야 한다. 그래서 본 연구에서는 용례 매칭 규칙, 구문패턴, 의미 유사도 등을 차례로 적용하여 후보명사의 의미를 분별하였으며, 또한 구문패턴의 빈도 정보를 이용하여 용례에 나타나지 않지만 구문관계를 형성할 수 있는 명사를 추출하여 구문관계를 확장하고자 하였다. 이러한 연구는 명사 중심의 어휘망이 용언과의 구문관계 구축을 통해 형태소 분석, 구문 분석, 의미 분석 등에 광범위하게 활용할 수 있는 어휘망의 기반을 다지는 작업이 될 수 있을 것이다.

According to the change in media environment, a support plan for local broadcast has been required. In terms of legal and institutional support for the development of local broadcast, the enactment of special Act for local broadcast has become a breakthrough. In this point of view, we analyzed the performance and the limitation of the special Act. As a literature research, analyzing the literature and related-ordinances, we have sought legal and institutional support plans for the local broadcast. As a result, with the Local Broadcast Development Council being in charge of legislative right and responsibility, a plan to empower them to have legal and institutional authority should be drawn; another plan to secure independence in operating a fund and to promote the capability to produce local broadcast programs and the distribution system should be drawn; the other elaborate plan for the locality index that assesses the locality is required. Local broadcast should be on a way to secure not only public interest and concern but locality and diversity; legal and institutional plans should be sought.

The efficient discovery of services from a large scale collection of services has become an important issue[7, 24]. We studied a syntactic method for Web service discovery, rather than a semantic method. We regarded a service discovery as a retrieval problem on the proprietary XML formats, which were service descriptions in a registry DB. We modeled services and queries as probabilistic values and devised similarity-based retrieval techniques. The benefits of our way are follows. First, our system supports ranked service retrieval by keyword search. Second, we considers both of UDDI data and WSDL definitions of services amid query evaluation time. Last, our technique can be easily implemented on the off-theshelf DBMS and also utilize good features of DBMS maintenance.

With the intensification of urban development in Chinese cities, mixed land use in urban centers extends vertically into 3-D and expands its scale from a single building to commercial clusters. The multi-level pedestrian system in city centers also changed its role from one of traffic isolation to spatial integration, where transit nodes, street sidewalks, squares, building entrances, atriums, and corridors are interconnected, both horizontally and vertically, into a whole spatial system, within which pedestrian flows are guided and shopping facilities are arranged. This paper uses spatial configuration analysis of space syntax to examine the impacts of spatial patterns on movement distribution and the business performance of tenant mix in the multi-level commercial system of the Nanshan Commercial Cultural District in Shenzhen, China. The key objective is to better understand the interactions between the socio-economic variables and spatial design parameters of a shopping complex. The research findings point to the importance of multiplicity between syntactic variables and other spatial variables in influencing the pedestrian flows, business performance and tenant mix in highly complex commercial systems. Particularly noteworthy is the relationship between spatial accessibility measures and the location of escalators, and the ways in which individual commercial buildings are embedded into the overall spatial system. The study suggests that this may lead to the preliminary identification of the spatial qualities of effective vertical extensions of mixed land use in a high-density urban settings.

구문분석에서 구문중의성(syntactic ambiguation)은 구문분석의 성능에 많은 영향을 미친다. 구문중의성을 일으키는 많은 요인들이 있지만, 특히 조사가 발달된 한국어의 구문분석에서 조사가 생략된 명사들은 구문중의성을 증가시키는 큰 요인 중 하나이다. 그렇기 때문에 조사가 없거나 생략된 연속된 명사열(contiguous nouns)의 길이가 길어질수록 구문중의성은 지수적으로 증가하게 된다. 따라서 현재까지의 연구에서는 이런 명사열들을 마치 하나의 명사처럼 구묶음을 하여 처리하는 경우가 많았다. 하지만, 조사가 없는 명사열들을 모두 하나의 명사구처럼 처리하여 구문분석을 수행할 경우, 주요 문장성분들이 잃어버리게 되는 경우가 발생한다. 따라서 본 논문에서는 하나의 명사처럼 쓰일 수 있는 조사가 없는 연속된 명사열을 복합명사구라고 정의하고, 두 개의 명사쌍으로 구축된 복합명사사전만을 이용하여 세 개 이상의 명사로 구성된 복합명사구들을 사전에 등록하지 않고도 복합명사구를 구묶음하는 방법에 대하여 기술한다. 실험을 위해 세종사전 150,546개의 예문에서 두 개 이상의 조사가 생략된 21,482개의 명사쌍을 추출하여 복합명사사전으로 변환하였으며, 총 6,316개의 사전 데이터가 구축되었다. 복합명사 구묶음 모듈은 조사가 생략된 명사열을 입력으로 받아서 우에서 좌로 검색하며 구묶음이 가능한 명사들을 연결하고, 연결된 명사들끼리 하나의 복합명사로 구묶음을 한다. 실험은 사전을 구축할 때 쓰였던 말뭉치와 사전을 구축할 때 쓰이지 않은 말뭉치를 이용하여 수행하였다. 결과는 사전을 구축할 때 쓰인 말뭉치를 이용하였을 때는 96.76%의 정확도를 보였으며, 사전을 구축할 때 쓰이지 않은 말뭉치를 이용하였을 경우는 12.23%의 정확도를 보였다.

Computational models up to now for Korean morphology have been linear in that it deal with only segmentation of morphemes rather than formation of the internal structure of a word. When integrating a linear computational model with syntax analysis, it requires an additional interface component between this model and the syntax to bind morphemes into sentence constituents. Furthermore the linear model is not semantically intuitive. In this paper, based on word-syntactical viewpoint, we propose an integrated computational model that deals with morpheme segmentation, formation of syntactic element (sentence constituent), and even internal structure of word. Formalism of two-level morphology is employed to cope with morpheme segmentation and alternation problems, and functional diacritics are proposed to incorporate categorial context into the two-level formalism. A modified GLR-based algorithm is also proposed to check syntactical constraint of morphemes.

RSS is a core component of Web 2.0 which is expected to lead the most important innovation in the new IT environment. In that sense, it is actively utilized to distribute Web contents in various areas such as news, blog, multimedia, medical information, and conference and journal information. Also, it is expected to be a major effective marketing tool in electronic commerce domain. In the paper, we analyzed the problems of current utilization of RSS in domestic shopping malls, and suggest requirements for the effective use of RSS in electronic commerce. Furthermore, we proposed various issues and answers on the implementation of the requirements, and designed the intelligent RSS framework for electronic commerce based on the issues. Syntactic and semantic interoperability between the RSS service provider and the user is one of the most important issues in the framework. We suggested how to implement the interoperability based on Semantic Web technologies.
