IT의 급격한 발전과 함께 새로운 형태의 정보 전달 방법이 지속적으로 나타나면서 우리말의 정확한 발음에 대한 인식이 점점 약화되고 있는 추세이다. 특히 장단음의 발음은 발화에 대한 전문인들도 정확하게 구분하지 못하고 있는 심각한 상황이다. 본 논문에서는 한국어 명사에서 나타나는 장단음화 현상을 주변 어휘와의 관계를 바탕으로 살펴보고 동음이의어 중 다르게 발음되는 명사의 장단음 구분을 명사와 명사의 수식어, 명사의 서술어와의 관계를 중심으로 논의한다. 분석된 결과는 결합범주문법을 이용하여 표현하고 어휘적 중의성이 해소된 음성 합성 과정을 표준화된 SSML(Speech Synthesis Markup Language)으로 기술한다.

A procedure of estimating failure probability is demonstrated for a pressurized pipe of CrMo steel used at $538^{\circ}C$. Probabilistic fracture mechanics were employed considering variations of pressure loading, material properties and geometry. Probability density functions of major material variables were determined by statistical analyses of implemented data obtained by previous experiments. Distributions of the major variables were reflected in Monte Carlo simulation and failure probability as a function of operating time was determined. The creep crack growth life assessed by conventional deterministic approach was shown to be conservative compared with those obtained by probabilistic one. Sensitivity analysis for each input variable was also conducted to understand the most influencing variables to the residual life analysis. Internal pressure, creep crack growth coefficient and creep coefficient were more sensitive to failure probability than other variables.

This paper describes BSDL(Behavioral/Structural Description Language), CDTF(Control Data Text File) and state synthesizer built for use in ICSC(InCheon Silicon Compiler). BSDL describes structral and behaviral specifications of an ASIC(Application Specific IC) for digital system design. ICSC's paser generates CDTF consists of if-then-else, arithmetic and data transfer statement according to each BSDL statement. State synthesizer generates CCG(Control Constraint Graph) in consideration of execution of statement and generates VCG (Variable Constraint Graph) in consideration use of variable generation and use of variable. Also, it involves allocating algorithm operation nodes in the data path and the control path to machine states with minimum state number and as small area as possible.

본 논문은 한국어의 특수조사, 특히 '도'의 의미, 문맥적 기능에 대하여 다루고 있다. '도'는 문맥의 자연스러운 연결에 있어서 중요한 역할을 수행한다. '도'가 쓰인 문장의 배경에는 반드시 일정한 전제가 존재한다. 전제는 그 문장의 의미 뿐만 아니라 기존 문맥과도 직접적으로 연관된다. 본 논문에서는 '같음', '유사함', '극한', '첨가' 및 병렬문에서 쓰이는 다섯 가지 '도'의 기능에 대하여 설명하고, alternatives semantics를 이용하여 이를 결합범주문법(CCG)에서 구현하는 방법을 제시한다.

격현상은 한국어의 여러 가지 문법현상들을 분석하고 이를 전산학적으로 구현하는데 아주 중요한 부분 중의 하나이다. 결합범주문법(Combinatory Categorial Grammar; CCG)을 이용한 대부분의 기존 연구들에서는 격조사나 보조사들에도 별도의 통사범주들을 할당한 후, 이들 조사들이 명사와 결합하여 하나의 명사구를 구성하는 것으로 조사들을 처리하고 있다. 그러나 이러한 방법들은 이론적인 문제점들뿐만 아니라 전산적 구현에 있어서도 문제점을 안고 있다. 본 논문에서는 이러한 문제점들을 해결하면서도 한국어의 격현상을 효과적으로 구현할 수 있는 방법을 소개한다. 본 논문에서 사용하려고 하는 문법공학 시스템은 한국어를 위한 유형상속 결합범주문법(Type-inherited Combinatory Categorial Grammar; TCCG)이다. 이 시스템 안에서는 명사구의 격조사나 보조사들이 별도의 통사범주들을 할당받지 않고, 명사의 굴절규칙(inflectional rules)에 의하여 명사와 결합하게 된다. 따라서 국어의 기본적인 격조사들을 효율적으로 구현할 수 있을 뿐만 아니라 보조사나 격조사 탈락현상들도 효과적으로 분석하고 구현할 수 있게 된다.

TCG는 Trading Card Game의 약자로 수집과 게임을 목적으로 디자인된 카드게임을 일컫는다. TCG는 1993년 미국의 수학자인 리처드 가필드(Richard Garfield)가 만든 '매직: 더 개더링'(Magic: The Gathering)을 시작으로 '스펠파이어'(Spellfire), '일루미나티'(Illuminati)와 같은 다양한 게임으로 이어지며 하나의 독자적인 장르로 자리매김하게 되었다. TCG는 전략적 게임 디자인을 통한 독자적 장르의 재미도 가지고 있지만, 수집 요소가 가진 장점으로 인해 많은 타 장르 게임에서 혼합되어 사용되고 있다. 본 논문에서는 최초의 TCG인 '매직: 더 개더링'의 분석을 통해 다양한 덱을 만들어내는 방법에 대해 연구하고 나아가 타 장르 활용 방안에 대하여 제시하고자 한다.

This paper deals with the statistical properties of parameters B and q in the creep crack growth rate (CCGR) law, da/dt=B$(C^*)^q$, in Mod. 9Cr-1Mo (ASME Gr.91) steel which is considered a candidate materials for fabricating next generation nuclear reactors. The CCGR data were obtained by creep crack growth (CCG) tests performed on 1/2-inch compact tension (CT) specimens under an applied load of 5000N at a temperature of $600^{\circ}C$. The CCG behavior was analyzed statistically using the empirical equation between CCGR, da/dt and the creep fracture mechanics parameter, $C^*$. The B and q values were determined for each specimen by the least-squares fitting method. The probability distribution functions for B and q were investigated using normal, log-normal, and Weibull distributions. As far as this study is considered, it can be appeared that B and q followed the log-normal and Weibull distributions. Moreover, a strong positive linear correlation was found between B and q.

This study was conducted to analyze genome of red sea cucumber and to use it as basic data for the development of genetic markers for red sea cucumber. Microsatellite marker analysis of Ulleungdo_normal and Ulleungdo_native red sea cucumbers revealed that dinucleotide simple sequence repeats (SSRs) had the highest ratio, at 81.3~81.4%, and the number of the detected SSRs tended to decrease as the number of repeating sequence units in SSRs increased. In general, microsatellites with between 5 and 10 iterations were most common. As the size of the SSR repeating sequence units increased, the SSR iterations gradually decreased. The di-, tri-, and tetra-nucleotides in SSRs were detected in the highest numbers as (AT)₅, (AAT)₅, and (AAAT)₅, respectively. (CG) and (CCG) had very low frequencies compared to the numbers of other repeating SSR units. The numbers of di-and tri-nucleotide repeats were up to 35 and 32, respectively, and then increased discontinuously up to 44 and 43 repeats, respectively. Tetra-, penta-, and hexa-nucleotides in SSRs occurred in numbers up to 25, 21 and 14, respectively. This analysis of red sea cucumber indicated that it maintains its own repetition sequence and repetition number; therefore, we suggest that using it as basic data for molecular marker will be possible in future research.

A method for the identification of Nocardia seriolae, the causative agent of nocardiosis in cultured fishes, using PCR was developed in the study. A PCR primer set specific to N. seriolae was designed based on 16S-23S rRNA sequence of various Nocardia species accessed in GenBank. Designed PCR primer set, Nseri-F (5'-GCA AAC TCT TCG AAC AGT CG-3') and Nseri-R (5'-GGA TAT CAG GAC TTA CCG GC-3'), amplifies the target regions of N. seriolae only, but not 4 other Nocardia species, N. asteroides, N. crassostreae, N. farcinica and N. salmonicida.

Mori Cortex Radicis, the root bark of mulberry tree, has been used in the treatment of bronchial asthma and other lung diseases in traditional medicine. There was a recent repor t that the water soluble part with molecular weight of above 10,000 has anti-allergic activity. Therefore, we intended to isolate and purify the anti-allergic compound from hot water extract of the Mori Cortex Radicis. Crude extract of Mori Cortex Radicis was prepared by hot-water extraction, and anti-allergic compound was further purified by alcohol precipitation, successive ultrafiltration, anion exchange chromatography and gel filtration chromatography. This compound had homogeneity which was shown by the sharp single peak in HPLC chromatogram (TSK-GEL G400OPW column, RI detector). The molecular weight of the compound was estimated as 23Kda on the basis of calibration curve plotted against protein standards. This compound was identified as complex of sugar, protein and lignin (19.2: 5.9: 72.7), and proteolysis could not decrease the anti-allergic activity but mild delignification decreased the activity remarkably. Therefore, we concluded that the anti-allergic compound of Mori Cortex Radicis was a lignin-carbohydrate complex.
