수화는 농인 사회에서 주로 사용되는 시각언어로서 음성언어인 한국어와 통사적인 측면에서 많은 차이를 보인다. 특히 수화에서는 조사와 어미가 거의 사용되지 않기 때문에 한국어 문장에서 기존의 방법대로 이들을 제거한 후 어순을 고려하지 않은 채 문장 성분의 기본형을 그대로 나열하여 수화문을 생성할 경우 문장 성분 간의 통사적 관계가 애매해질 수 있다. 본 논문에서는 통사적 중의성이 한국어 문장을 수화문으로 변환하는 과정에서 추가적으로 나타나게 되는 특정 통사구조에 의해 발생하는 것으로 보고, 이러한 통사구조를 기본논항구조, 한정수식구조, 병렬구조, 서술구조로 분류하여 각각을 파악하고 그에 따라 통사적 중의성을 해소하는 방법을 제시한다.

현재 4차 산업혁명으로 인해 많은 이들의 삶의 질이 이전보다 개선되었음에도 불구하고, 소외된 계층을 위한 개발은 타 분야에 비해서 더뎌지고 있는 실정이다. 현대의 청각 장애인과 언어 장애인들은 시각 언어인 수화를 이용하여 의사소통을 한다. 그러나 수화는 진입 장벽이 높기 때문에, 이를 사용하지 않는 사람들은 청각 장애인 및 언어 장애인과 의사소통을 하는데 어려움을 겪는다. 본 논문은 이러한 불편함을 줄이기 위해 서포트 벡터 머신(Support Vector Machine, SVM) 기반의 HOG(Histogram of Oriented Gradients) 특징 벡터를 이용하여 수화의 기본인 숫자를 분류할 수 있는 시스템을 구현하여 수화를 번역할 수 있는 가능성을 제안한다.

This study was conducted to investigate the influence of formulation of fungicides on epicuticular waxes in 'Campbell Early' grapes. Non-bagged and bagged berries were treated with wettable powder, suspension concentrate and emulsifiable concentrate 15 days after full bloom (DAFB) and 48 DAFB (veraison), respectively. Fruit skin was observed by naked eye and scanning electron microscope (SEM) at harvest. Remarkable white blots were observed on the berries treated 48 DAFB in the order of wettable powder, suspension concentrate, and emulsifiable concentrate. The observation by SEM showed all formulations of fungicides damaged the ultra-structure of epicuticular waxes; also, an unknown substance was observed on treatment with wettable powder and suspension concentrate. Moreover epicuticular wax appeared to be melting on the grapes treated with emulsifiable concentrate. Also, non-bagged grapes showed serious contamination of epicuticular wax by some unknown substance, but bagged grapes had only fungicides' traces.

This study identities various types of subjective perception of hearing-impaired persons on sign language interpretation using Q-methodology in an attempt to explore ways for developing more useful sign language interpretation services for them. For this purpose, 35 statements are extracted based on literatures and in-depth interviews and Q-classification is conducted for 20 interviewees. The results identify a common perception on the provision of sign language interpreter to frequently used institutions of hearing-impaired persons. They also derive three distinguished types of perception: seeking specialization of sign language interpretation, seeking traditional sign language interpretation services and seeking expansion and improvement of sign language interpretation services. Based on the results, the study suggests residence of sign language interpreters in public facilities, improvements of qualification system and education and training courses, specialization by field and improvement of the practice of sign language interpretation services, provision of customized services to the elderly and use of sign language interpreters reflecting the needs of the users.

In this paper, we propose recognition system which tracks the unmarked hand of a person performing sign language in complex background. First of all, we measure entropy for the difference image between continuous frames. Using a color information that is similar to a skin color in candidate region which has high value, we extract hand region only from background image. On the extracted hand region, we detect a contour and recognize sign language by applying improved centroidal profile method. In the experimental results for 6 kinds of sing language movement, unlike existing methods, we can stably recognize sign language in complex background and illumination changes without marker. Also, it shows the recognition rate with more than 95% for person and $90\sim100%$ for each movement at 15 frames/second.

Sign languages, commonly used in aurally challenged communities, are a kind of visual language expressing sign words with motion. Spatiality and motility of a sign language are conveyed mainly via sign words as predicates. A predicate is modified by an adverbial phrase with an accompanying change in its semantics so that the adverbial phrase can also affect the overall spatiality and motility of expressions of a sign language. In this paper, we analyze the semantic features of adverbial phrases which may affect the motion-related semantics of a predicate in converting expressions in Korean into those in a sign language and propose a system that generates corresponding animation by utilizing these features.

The temperature crack of concrete structure is caused by the phenomenon which the concrete volume is restricted in the inside or outside part due th the temperature variations induced by the hydration heat of cement. And mass concrete structures are weak in temperature crack. Seongdeok multi-purpose dam is gravity dam which is being constructed in Cheongsong-gun, Gyeonsangbuk-do. Upstream cofferdam was constructed to examine the temperature crack due to hydration heat and to decide the height of placement. Therefore this study performed the hydration heat analysis of Seongdeok upstream coffer dam to analyze the hydration heat according to different height of placement and to compare with measured results.

In this paper, we propose sign language morpheme generation rule corresponding to morpheme analysis for each part of speech. Korean natural sign language has extremely limited vocabulary, and the number of grammatical components eing currently used are limited, too. In this paper, therefore, we define natural sign language grammar corresponding to Korean language grammar in order to translate natural Korean language sentences to the corresponding sign language. Each phrase should define sign language morpheme generation grammar which is different from Korean language analysis grammar. Then, this grammar is applied to morpheme analysis/combination rule and sentence structure analysis rule. It will make us generate most natural sign language by definition of this grammar.

매스콘크리트에서는 수화열에 의하여 유발된 높은 온도가 열응력을 일으키는 원인이 되며 구속의 정도에 따라 인장응력이 발생되어 균열이 발생하게 된다. 따라서, 매스콘크리트 타설시 시멘트의 수화열에 의한 균열이 심각한 문제가 된다. 본 연구에서는 매스콘크리트 기초 및 교각구조에 대한 수화열 실험을 통해 온도분포 및 변형분포를 측정하고 이에 대한 온도 및 열응력 해석을 통해 매스콘크리트에 대한 수화열 특성을 규명하였다.

PWR 원전에서는 계획예방 정지운전시 효과적인 정지수화학 제어에 의해 일차계통 방사능 준위를 감소시키고 작업종사자의 피폭을 최소화하기 위해 정지운전 자료에 대한 보다 정확한 해석이 필요하다. 본 연구에서는 국내 PWR 원전 주기(A호기의 I 및 II주기와 B호기의 II주기)별 정지수화학 특성을 SCALP(Shutdown chemistry CALculation Program)프로그램으로 계산하고 정지운전 기간중 일차냉각재계통에서 제거되는 방사능량에 영향을 미치는 정지수화학 특성을 주요 인자별로 평가하였다.
