  • This study was conducted to evaluate the effects of bastnasite nitrate fertilizer (BNF) on the growth of creeping bentgrass. Fertilizer treatments were designed as follows; non-fertilizer (NF), control (CF; compound fertilizer), RE-l (CF+0.3 $g{\cdot}m^{-2}$BNF), RE-2 (CF+0.5 $g{\cdot}m^{-2}$BNF), RE-3 (CF+1.0 $g{\cdot}m^{-2}$BNF) and RE-4 (0.5 $g{\cdot}m^{-2}$BNF). Every treatment was arranged in a randomized complete block design with three replications. In creeping bentgrass, turf qualities such as turf color index and chlorophyll index, shoot number, clipping dry weight and nutrients of tissue were measured. It was hardly affected by BNF application in investigation of chemical properties of the soil. By applying BNF, turf color index and chlorophyll index in RE-2 were increased 3.9% and 9.2% more than NF. As applied BNF on creeping bentgrass, shoot number was increased 9% in RE-4 more than NF and 22% in RE~2 more than CF. It was increased in N uptake and clipping dry weight of creeping bentgrass by supplying BNF. These results indicated that the BNF application promoted a turf qualities and a growth of creeping bentgrass by advancing N uptake and shoot number.

  • Induction of cytochrome P45O (CYP) and 7-etholqresorufin-O-deethylase (EROD) in the microsome exposed to 3-methylcholan-throne (MC), $\beta$-naphthoflavone (BNF) and phenobarbital-Na (PB) was investigated, Microsome was isolated from digestive gland of clam (Coelomactra antiquata) and then exposed to each chemical in concentration range of 0.1 to 1.0 mM for 7 hours. The CYP content and EROD activity in the microsome exposed to each chemical significantly increased compared to the control group. The overall CYP and EROD induction potency was in order of MC>BNF>PB. The induction response of EROD was two times higher than that of CYP level in the microsome exposed to MC, but the induction response of EROD was slightly higher than that of CYP level in BNF and PB exposure groups.

  • Cytochrome P450 (CYP) induction was determined in microsomes of three aquacultured fish species (Sebastes schlegeli, Paralichthys olivaceus and Pagrus major) and two wild fish species (Mugil cephalus and Stephanolepis cirrhifey) in vitro exposed to $\beta$-naphthoflavone (BNF). The microsomes of five fish were exposed to BNF (5 mM or 10 mM) in dimethylsulfoxide at $30^{\circ}C$ for 9 hr. The CYP contents in most fish increased according to exposure duration for 3 or 5 hour, and then decreased, while steady increase of CYP was observed in P. major for 9 hour. The induction of CYP contents in aquacultured fish species (207~422%) were higher than those in wild fish species (206~207%).

  • Accordingly it is very important to not only develop the stack of protocol, but also try an international standardization regarding the standard protocol of VoIP. Has compared to the advanced countries having already some success in commercialization, Korea is relatively much less involved in relation to this technology and endeavors. In this regards, this paper is focused on developing a protocol stack made with encoder/decoder, the generator or the header file, syntax analyzer etc. based on the protocol grammars of Session Description Protocol supported by IETF RFC2327. For the sake of it, first describe the SDP BNF grammar based on IETF RFC2327 Augmented BNF. And then we produce the Abstract Syntax Tree, header file generator for encoding/decoding as applying the method of syntax directed to SDP protocol grammar.

  • 현대의 데이터베이스 서버는 거대하고 복잡한 소프트 시스템의 구조이다. 복잡한 SQL(Structured query language) 언어는 점점 늘어가고 ANSI 표준을 바탕으로 새로운 형태로 발달하고 있다. 데이터베이스 서버를 테스트하는 작업은 꾸준히 진행되어 왔으며 앞으로도 계속 도전하고 있는 과제중 하나이다. 그 과제에 적합한 새로운 테스트 기법의 개발을 위해서는 보편적으로 막대한 인력과 비용이 요구된다. 본 논문에서는 수동적인 테스트에서의 막대한 인력과 비용의 문제로부터의 해결책을 제공하기 위해서 자동화된 SQL 쿼리 테스트 프레임워크를 제시한다. 본 프레임워크는 SQL의 기본이 되는 SQL BNF(Backus-Naur Format) 문법을 기본으로 하여 문법적, 의미적으로 정확한 "지능적인" SQL 쿼리를 랜덤하게 자동적으로 생성 한다. 생성된 "지능적인" 쿼리는 논리적 모델에서 얻어지고, 통계적인 정보를 통해 사용자에게 유용한 체크리스트를 제공한다. 각각의 데이터베이스 개발업체는 그들의 데이터베이스와 새롭게 개발되는 데이터베이스를 통합적으로 테스트 환경을 제공함에 따라 테스트 과정에서의 인력과 비용의 문제를 해결하고, 데이터베이스의 장단점을 파악하는 기준을 제공하여 품질 향상에 도움이 될 것이다.

  • Modern enterprise may be in need of developing the right application programs under rapidly changing business environment in fast time-to-market. But Most of enterprise without business process mechanism are very hard to develop the application needed in time when it will be changing their business. To solve this problem, we propose the business process framework based on the closed architecture. This approach is to develop the right application with reusing software modules in time and easily under rapid business process changing/improving through mapping BPM(Business Process Model), SOA(Service Oriented Architecture), and CBD(Component Based Development). we also define 5-Layers of BPF(Business Process Framework), and BNF(Backus Naur Form) for structuring BPF.

  • We propose an extended hypertext data model based on object oriented paradigm that can easily the real world and semantics. We use the BNF notation to formalize the model. In our model, We introduce conceptional navigation by associating semantics on links and drive intelligent navigation using weights on links to alleviate user disorientation problem which is currently somewhat vague. We functionally classify the hypertext node into three types:Indexing node, Content node, Extract node and likewise classify the link into Alink type, Rlink type, Slink type. We believe that the typed node and typed link approach accommodate efficient query/search in hypertext.

  • We present and discuss a Korean language parser based on dependency grammar, subcategorization, and the analysis of viable postfix such as josa and omi. We employ an extended form of BNF(Backus Naur Form) to define the dependency grammar and the form of subcategorization. We present the conceptual form of Korean language parser in a C program style. We discuss the structure of Korean parser currently implemented and show the execution results.
