2000년대 중반 세종 구구조 구문분석 말뭉치가 배포된 이후 의존 구문분석이 구문분석 연구의 주요 흐름으로 자리 잡으면서 많은 연구자들이 구구조 구문분석 말뭉치를 개별적으로 의존구조로 변환하여 구문분석 연구를 수행하였다. 하지만 한국어 문장의 의존구조 표현에 대한 논의가 부족하여 서로 다른 의존구조로 변환 후 구문분석을 연구함으로써 연구 효율성이 저하되는 문제가 발생하였다 본 연구에서는 이와 같은 문제에 접근하기 위하여 한국어 문장에 대한 의존관계 가이드라인을 제안한다. 그리고 제안하는 가이드라인을 기반으로 구축한 엑소브레인 언어분석 말뭉치(725 문장)에 대해 소개한다.

Universal Dependency 프로젝트는 여러 언어에 공통으로 적용할 수 있는 형태소 패턴과 구문 관계를 찾기 위한 연구를 진행하고 있으며, 점진적으로 많은 언어들이 참여하여 UD 가이드라인에 따라 말뭉치를 구축하고 시스템을 개발하고 있다. 한국어 UD 말뭉치도 구축되어서 공유되고 있지만 구축을 위한 상세한 가이드라인은 제공되지 않고 있다. 본 논문에서는 UD를 기반으로 한국어 구문분석 말뭉치를 구축할 때 논의되어야 할 요소들을 나열하고 예제를 통해서 설명하였다. 본 연구를 기반으로 한국어 구문분석 말뭉치 구축, 구문분석 시스템 개발에서 UD 가이드라인을 적용하는 논의가 시작되기를 기대한다.

의존구문분석은 문장을 의존관계(의존소-지배소)로 분석하는 구문분석 방법론이다. 현재 사전학습모델을 사용한 전이 학습의 딥러닝이 좋은 성능을 보이며 많이 연구되지만, 데이터셋에 의존적이며 그로 인한 자료부족 문제와 과적합의 문제가 발생한다는 단점이 있다. 본 논문에서는 언어학적 지식에 기반한 강화된 지배소-의존소 제약규칙 에지 알고리즘을 심층학습과 결합한 모델을 제안한다. TTAS 표준 가이드라인 기반 모두의 말뭉치로 평가한 결과, 최대 UAS 96.28, LAS 93.19의 성능을 보였으며, 선행연구 대비 UAS 2.21%, LAS 1.84%의 향상된 결과를 보였다. 또한 적은 데이터셋으로 학습했음에도 8배 많은 데이터셋 학습모델 대비 UAS 0.95%의 향상과 11배 빠른 학습 시간을 보였다. 이를 통해 심층학습과 언어지식의 결합이 딥러닝의 문제점을 해결할 수 있음을 확인하였다.

Competition among local governments in a competitive global festival and the festival is going to become the intensify regional strategies as enabled by the improved local image production and has been a symbol of the festival and each municipality is competitive. Is required as a symbol for the symbol can be passed to the consumer in this situation differentiated festive images efficient communication studies on the character. When viewed as a symbolic sign for the character representation of activities for the festival, Can provide a logical framework that is distinct from the idea of a character who relies on intuition and the creative semiotics. In this research paper a semiotic analysis of the character and the character string to enhance communication efficiency concept, Festival effect, we analyzed the correlation of the local culture. Empirical analysis of consumer images, Shared on the basis of empirical results to the consumer means, the paper shows that the influence of each of the other factors is reflected in the character according to the signifier local cultural characteristics and a character region on the concept of a character form culture semiotics interpretation element influences the guidelines of the characters that may be produced.

The ultimate research goal of the current study was a development of hydrolyzed whey protein powder (7%-GNANA) manufactured with normal content of sialic acid, a marker compound, that is naturally occurring at 7% concentration in GMP obtained from the milk protein. GMP is a safe food, used worldwide in infant and baby foods, etc. The test substance was prepared using (7% sialic acid containing) GMP as a raw material, and then using alcalase, an enzyme approved as a food additive, after separation of sialic acid with 100% efficiency and 7%-GNANA (containing 7% sialic acid and protein; product name: HELICOBACTROL-7) provided by MEDINUTROL Inc. (Korea). Bacterial reverse mutation (Ames) test was conducted in accordance with GLP Guideline using the test substance specified above. To identify its mutagenic potential against microorganisms, histidine auxotrophic strains of Salmonella Typhimurium, TA98, TA100, TA1535, and TA1537, and tryptophan auxotrophic strain of Escherichia coli, WP2uvrA, were used. The bacterial reverse mutation (Ames) test was performed by dividing the test substances into five different concentration groups (0, 61.7, 185, 556, 1,670, $5,000{\mu}g/plate$). Results of this experiment did not reveal repetitive increase of colony generating values or positive criteria for reverse mutagenicity for any concentration of test substances in any of the five strains, regardless of the presence of a metabolic activation system, and no dose-dependency was identified. In conclusion, the safety of 7%-GNANA test substance was verified by bacterial reverse mutation test conducted before registration of 7%-GNANA as a food additive.

Breast cancer is the most common form of cancer among korean woman. Therefore, the early detection activities of breast cancer such as breast self-examinations, clinical breast examinations, mammography are important. A yearly mammography examination has been recommended for women aged 40 and older for the early detection of breast cancer in asymptomatic periods. However, the glandular tissue of breast is the most radiation-sensitive tissue, and the determination of average glandular dose (AGD) forms an important part of the quality control of the mammographic systems. Because of the difficulty of estimating AGD directly, it is often estimated from the measurements of the incident air kerma and by applying the appropriate conversion factors. The primary objective of this study was to standardize the method of measuring AGD. The secondary objective was to evaluate the relationships between AGD per various composition and thickness of the breast using Monte Carlo simulations. As a result, we standardized the method of measuring AGD according to International Atomic Energy Agency (IAEA) guidelines (CoP: an international code of practice). Overall, AGD for mammographic practice in Korea was less than 3.0 mGy recommended by the Korea Food and Drug Adminstration (KFDA) protocol, and Korean Institute for Accreditation of Medical Image (KIAMI). The measured and simulated AGD for a given condition were calculated as 1.7 and 1.6 mGy, respectively. For the AGDs obtained, there was no significant difference between them. The simulated AGD was dependent on the fraction of glandular tissue of the breast. The AGD increases with increasing of the breast glandularity due to increasing absorption of low energy photons. The AGD also increases as a function of breast thickness. In conclusion, the results of this study could be used as a baseline to establish a reference level of radiation dose in mammography.

The current study analyzed the relationship between expression type of humor ads and their advertising effects and the differences in advertising effects by expression type according to temperament as categorized by the Myers-Briggs Type Indicator (MBTI). Expression type of humor was classified into arousal-, incongruity-, and superiority-type humor ads. Advertising effects were measured by consumers' cognitive, affective, and conative responses. Three ads were created based on expression type of humor. A personality type, as measured by the MBTI, was categorized into four types of temperament, namely SP, SJ, NF, NT and used as moderating variables. As a result, the advertising effects varied according to the expression type of humor advertising. Interaction effects between ad expression type and temperament on ad feeling and ad preference were also found.
