본 논문에서는 형태소 수준의 결합범주문법을 이용하여 형태소 분석을 포함한 자연언어처리의 여러 단계를 한 단계의 유도과정으로 처리하고 형태소 분석 단계에서 증가하는 애매성과 복잡도를 상위 분석 단계의 정보를 사용하여 줄이는 방법에 대해서 논한다. 한국어에서 나타나는 복잡한 언어 현상 중에 하나인 용언의 불규칙 활용을 확률 정보뿐만 아니라 음운정보를 포함만 통사 정보나 의미 정보 등의 상위 정보를 사용하여 처리하여보고 일반적인 형태소 분석기로서의 발전 가능성에 대해서 알아본다.

This paper investigates the nature of Japanese argument cluster (Steedman 2000b). Based on Combinatory Categorial Grammar, a type-raising analysis of case particles which captures some aspects of the information structure in Japanese is discussed, including contrastive interpretation of coordination, wh-constructions, and some theme and rheme-related grammatical phenomena. These observations offer further support for the study of syntax, semantics, and phonology interface and the earlier analysis of English information structure.

현재 소프트웨어 개발에서 증가적으로 채택되고 있는 컴포넌트 기반 소프트웨어 엔지니어링(CBSE)에서, 새로운 프레임 ？에서의 컴포넌트의 효율적인 동작을 위한 컴포넌트 변형이나, 컴포넌트 통합은 활발히 연구가 진행중이나, 변형이나 통합으로 인하여 발생 할 수 있는 오류들을 테스팅하는 방법이과, 툴은 부족한 현실이다. 본 논문에서는 컴포넌트의 통합, 변경시 발생할수 있는 에러들을 쉽게 검출하기 위하여 본 논문에서 제안한 CCG(Component Calling Graph)를 이용하여 컴포넌트간의 의존성을 추적하고 selection 알고리즘을 거친 테스트 케이스 추출을 통한 컴포넌트의 효율적인 테스팅 방법을 제안하였다.

A commutative productive category is proposed to the current CCG for the syntactic analysis of free word order languages like Korean. The introduction of this sort of category is quite natural for categorial lexicon and functional operations. We present the theorical basis of productive category and examine the linguistic availability through typical syntactic structures of Korean.

Background: A disputed rpoB mutation is a specific type of rpoB mutation that can cause low-level resistances to rifampin (RIF). Here, we aimed to assess the frequency and types of disputed rpoB mutations in Mycobacterium tuberculosis isolates from South Korea. Methods: Between August 2009 and December 2015, 130 patients exhibited RIF resistance on the MTBDRplus assay at Asan Medical Center. Among these cases, we identified the strains with disputed rpoB mutation by rpoB sequencing analysis, as well as among the M. tuberculosis strains from the International Tuberculosis Research Center (ITRC). Results: Among our cases, disputed rpoB mutations led to RIF resistance in at least 6.9% (9/130) of the strains that also exhibited RIF resistance on the MTBDRplus assay. Moreover, at the ITRC, sequencing of the rpoB gene of 170 strains with the rpoB mutation indicated that 23 strains (13.5%) had the disputed mutations. By combining the findings from the 32 strains from our center and the ITRC, we identified the type of disputed rpoB mutation as follows: CTG511CCG (L511P, n=8), GAC516TAC (D516Y, n=8), CTG533CCG (L533P, n=8), CAC526CTC (H526L, n=4), CAC526AAC (H526N, n=3), and ATG515GTG (M515V, n=1). Conclusion: Disputed rpoB mutations do not seem to be rare among the strains exhibiting RIF resistance in South Korea.

The purpose of this study is to evaluate children who underwent hepatic resection for primary malignant hepatic tumor in the period from January 1994 to December 2001. A total of 8 patients, seven with hepatoblastoma (HB) and one with hepatocellular carcinoma (HCC), were studied. One HCC was resectable at the initial diagnosis, but five cases of unresectable HB received two cycles of transarterial chemoembolization (TACE) before operation. One patient with an unresectable HB with bone marrow metastasis was operated after one cycle of TACE and one cycle of systemic chemotherapy based on CCG-823F protocol. Another unresectable HB patient received systemic chemotherapy instead of TACE before operation. Postoperative chemotherapy was administered to all of the patients after complete surgical resection on CCG-823F protocol. All 6 patients who underwent TACE and neoadjuvant chemotherapy showed marked reduction in tumor volume and a clear outline of the lesion. Major complication was not noticed. Mean alpha-fetoprotein (${\alpha}$-FP) level at diagnosis, after neoadjuvant chemotherapy and after postoperative chemotherapy was 9,818 (42-35,350), 664, and 10.1 ng/mL, respectively. Half life of the ${\alpha}$-FP after complete resection was 5.1 days (3.0-8.7 days). Median follow up period was 57.1 months (10-97 months) and all the patients are alive with NED. In conclusion, preoperative chemotherapy, especially TACE, is effective, safe, and useful to treat initially unresectable hepatoblastoma, and serial level of the serum ${\alpha}$-FP is a useful tumor marker for diagnosis and monitoring therapeutic responses.

한국형 수집 RPG는 스마트폰이라는 새로운 환경에서 발전한 독특한 RPG의 하위 장르다. 일본 CCG를 뿌리로 두지만, MMORPG 개발의 경험적 요소와 특화된 개발력을 바탕으로 액션성을 더해 자신만의 색깔을 갖출 수 있었다. 장르가 등장한 이후 많은 게임들이 출시되고, 놀라운 성공을 거두기도 했다. 이런 성공은 국내에만 한정된 것이 아니라 해외로까지 뻗어가고 있다. 본 연구는 이런 한국형 수집 RPG의 등장 과정과 성공의 이유를 찾아보고, 이 중 대표적인 게임으로서 국내에서 큰 성공을 거두었던 "세븐나이츠", 세계적으로 큰 성공을 거둔 "서머너즈워"를 분석하고자 한다. 이를 통해 한국형 수집 RPG가 가지는 세계적 경쟁력을 확인하고, 예상되는 위험 요소를 살펴봄으로써 한국 스마트폰 게임 산업의 경쟁력 제고에 기여하고자 한다.

고분자전해질 연료전지(PEMFC)의 핵심부품인 스택의 MEA는 전극과 멤브레인 전해질, GDL(Gas Diffusion Layer)로 구성되며, 전극은 Anoth극과 Cathod극으로 나뉘어 각각의 전극 특성에 적합한 전극촉매를 적용하게 된다. Anoth극과 Cathod극은 탄소 지지체 위에 원하는 사양의 희유금속이 도포되어 존재하는데 이들 희유금속은 그 희귀성으로 인해 사용 후 반드시 재사용되어야 한다. 사용된 전극에서의 희유금속 회수는 산침출, 불순물제거, 추출, 탈거 공정으로 이루어지며, 산침출 시 산화제로 사용된 NaOCl로 인한 침출용액 내의 Na+ 이온의 증가는 불순물제거 공정에 의해 반드시 제거되어야 한다. 따라서 본 연구에서는 CCG 방식으로 전극촉매를 GDL에 코팅한 MEA로부터 백금족 희유금속을 회수 시 MEA에 포함되어 있는 소량의 불순물을 제거하고자 한다.

Acrylamide is present as a contaminant in heated food products, predominantly from the precursor asparagine. Nonanchored inter simple sequence repeats (ISSRs) are arbitrary multiloci markers produced by PCR amplification with a microsatellite primer. In order to assess the feasibility of microsatellite primers as markers for DNA damage, the study was conducted on common bean (Phaseolus vulgaris L.) exposed to different concentrations of acrylamide. Polymorphisms were abundant among plant samples treated with acrylamide in comparison to control (untreated one) tested with 4- tri-nucleotide, 2 tetra-nucleotide, and 3- dinucelotide primers. The primer (CCG)4 was the best tested primer to generate polymorphism between the DNA of plants treated or not by acrylamide. Polymorphisms became evident as the presence and absence of DNA fragments in treated samples compared with the untreated one. The highest number of DNA variation on ISSR patterns was observed at the micromollar concentrations of acrylamide. Acrylamide was able to induce DNA damage in non concentration-dependent manner with effectiveness at micromollar concentrations. This study demonstrated that ISSR markers can be highly reliable for identification of DNA damage induced by acrylamide.

Positive type presensitized offset plate developer were blended by quantitative analysis method. The test had been proceeeded to check variation of developability, shelf life and tone reproduction by SiO2/Na2O ratio to PS plate developer, added glycerin, and sodium phosphate with glycerin. This study of tone reproduction had been tested 5 times to get accuracy by PS platesusing kodak CCG C-3, KMS. The test result of tone reproduction of presensitized offset plates can be summarized as follows ; major compositions in positive type plate developer were Na, Si, K and P, developability were increased by Sio2/NaO2 ratio in positive type plate developer. Shelf life can be kept by add glycerin to positive type plate developer. Tone reproduction were improved by sodium phosphate due to buffer action while shelf life can be kept by add glycerin in positive type plate developer.
