본 논문은 구문패턴과 의미망을 이용하여 복합명사를 생성하는 방법을 제안하고, 제안된 방법으로 설계 구현된 시스템, 복합명사 생성기(Compound Nouns Generator : CNG)를 제시한다. 복합명사에 관한 연구는 형태적, 구문적, 의미적인 관점에서의 분석과 생성에 이르기까지 폭넓게 진행되고 있다. 본 논문에서는, 사전에 등재된 표제어만을 복합명사로 인정하고, 나머지는 1차적으로 명사 연결구로 파악한다. 그리고 이것을 다시 신형 복합명사와 명사 연결구로 파악함으로써, 복합명사에 대한 명확한 기준을 제시하여 자연언어처리, 정보검색 등에서 효율성을 높이고자 하였다. 본 논문에서 제안한 시스템은 복합명사 확장을 위해 구문패턴을 자동 생성함으로써 시스템의 융통성을 향상시키고, 구문패턴과 의미망을 통해 생성된 복합명사와 명사 연결구의 말뭉치상의 빈도정보를 이용함으로써 고빈도의 명사 연결구가 복합명사로서 굳어질 수 있는 가능성을 보여주기도 한다. 또한, 구문패턴과 의미망을 통해 생성된 명사 연결구를 비교하여 생성된 신형 복합명사는 구문패턴에 의해 뜻풀이가 자동으로 생성된다.

Statement of problem: A casting connection technique is widely used for repair, correction and addition to base metal framework. However, a casting connection technique may increase the risk of failure in clinical situations when high stresses exist. Purpose: The purpose of this study was to investigate the mechanical retentive groove design comparatively to increase the joint strength by using the three-dimensional finite element analysis model of a 3-unit fixed partial denture. Material and methods: Ten finite element models were constructed. (Model A: One retentive groove, Model B: Two retentive grooves, Model C: Three retentive grooves, Model D: Four retentive grooves, Model E: One horizontal groove and two vertical grooves, Model F: Two horizontal grooves and one vertical groove, Model G: One groove with the enlarged dimension, Model H: Two grooves with the enlarged dimension, Model I: One groove with the increased height, Model J: One groove with the increased width of base). The vertical force was applied to the mesial and the distal fossa to the casting connection of mandibular first molar. Results: The main factors, affecting joint strength of casting connection were both the retention between the primary cast and the secondary cast and the thickness of the primary cast remaining after preparing retentive groove. The increase of retentive force, according to the numbers and the dimension of retentive groove had an effect on distributing stress. However, in some cases, the increase of retentive force resulted in the increase of stress by reducing thickness of the primary cast in the connection area. Conclusion: The design of retentive groove that limits number of retentive groove for metal thickness and increases the depth of retentive groove for retention is highly recommended.

암반발파에 사용하고 있는 전기식 뇌관과 비전기식 연결뇌관 및 번치 커넥터(Bunch connector), 점화구, 에멀젼류 폭약이 지상에서 기폭 될 때 발생하는 소음을 비교 분석하였다. 에멀젼류 폭약의 폭발소음과 화공품의 기폭소음에 대한 추정식을 도출하였다. 에멀젼류 폭약의 폭발 소음 예측은 반대수 자승근 환산식, 번치 커넥터, 전기식 뇌관 및 비전기식 연결뇌관 및 점화구는 전대수식이 적합한 것으로 판단된다. 소음원으로부터 동일한 거리에서의 소음은 점화구, 비전기식 연결뇌관, 전기식 뇌관 및 번치 커넥터 순으로 높았다. 소음원으로부터 약20∼30m거리의 범위에서 번치 커넥터의 기폭소음은 에멀젼류 폭약 0.250kg의 폭발소음보다 약15.6∼20.2dB(A) 낮고, 비전기식 연결뇌관 보다 약13.5∼16.0dB(A) 높고, 전기식 뇌관 보다는 약6.5∼7.5dB(A) 높게 됨을 알 수 있었다. 점화구는 약20m 거리에서 약 7dB(A)이하 이었다. 에멀젼류 폭약의 폭발과 번치 커넥터의 기폭소음에 미치는 주(主)소음원은 에멀젼류 폭약의 약량과 번치 커넥터의 도폭선임을 확인하였다.

The purpose of this paper is to investigate the phenomena of preposing and inversion in English from the discourse-pragmatic perspectives. We claim that different types of preposing can be unified to a single process of topicalization. We also show that diverse discourse functions of inversion can be subsumed under the ‘linking’ function with the prior discourse. It is followed a comparative discussion between preposing and inversion to find what similarities the two constructions share and what differences there exist between the two. It is concluded that the choice of a syntactic forms ultimately depends on the speaker's evaluation of the information status of the knowledge store of the hearer.

Cognitive decline in aging is known to yield detrimental effects in syntactic processing and working memory capacity is the most crucial cognitive function in understanding older adults' sentence processing skills. This study examined how young and older adults utilize contextual information while resolving NP-attached Ps vis word-by-word self-paced reading paradigm. In addition, the study asked which cognitive functions play roles on the use of a NP-supporting context during processing of NP-attached PP. When NP-attached PP was presented in a supporting context, both age groups performed faster than in the null context condition. Among different cognitive functions, alternating attention skills were correlated with the ability utilizing context during syntactic ambiguity resolution and working memory capacity was not found to be crucial for this study. In conclusion, this study suggests that aging does not always affect older adults' syntactic processing negatively and relevant cognitive function may vary depending on the type of syntactic structure.

대양을 항해하는 Puser-Barge선의 내항성능과 그연결장치에 작용하는 피랑하중을 추정하기위하여,규칙피중 선체운동응답과,파랑하중응답을 Strip이론으로 구하는 해석적인 방법을 개발하였다. 연결장치의 종류로는 2개의 핀으로 연결되는 힌지연결의 경우와, 3개의 핀으로 연결되는 고정연결의 경우를 고려하였다. 이론 계산결과를 확인하기 위한 모형시험을 힌지연결의 경우에 대하여 정면규칙파중에서 실시하였다. 실험결과와 이론계산결과는 비교적 잘 일치하였다.

Experiments on the yield strength of pipe connectors made of metal wire, joint pins, pole pipes, multi span insertion joints, and T-clamp joints used in pipe houses were conducted. The strength of connections of a pipe connector made of metal wire was adequate but it had a big difference according to loading direction. Therefore as it is installed, its direction should be taken into consideration. The collapse load of pipes connected with a joint pin was lower than that of single pipes. In the part of frame member at which the great bending moment occurs, the use of joint pin should be avoided. Also experimental results showed that pole pipes for use in a part of frame buried under the ground were safe, and the strength of multi span insertion joints should be increased. The resistant moment of T-clamp was about 13.7% of a single pipe. In case that the external forces acting on left and right rafter are different. a unsymmetrical rotational force is produced at the multi span joint. If it is expected that the actual bending moment on the multi span joint is larger than resistant moment of T-clamp, a reinforcement to safely resist the rotational force is required.

Among the firefighting facilities, the fire department connection during firefighting is more important than any other facilities at the firefighting site to supply fire water. This study examined the water supply port of a fire department connection installed at an apartment building based on the Standard for Fire Safety (NFSC 502). The time of discovery was measured by fire fighters who knew or did not know of the water supply port installed in the apartment building, and by separating day and night. To maximize the use of the fire department connection which is the full fire extinguisher facility used by the fire brigade based on the results of the experiment, the author suggests improvement proposals that can clarify the installation location and install the location sign of the fire department connection for the Standard for Fire Safety (NFSC 502).

Existing wood decks brings out negligent accident because fastener can be pulled-out by cyclic load of pedestrians. When deck and joist are connected, it also causes the problems, which are cracking of wood decks and rapid decay by material of fastener. In this study, strength property of deck unit using reinforced plastic connector made by domestic A company was evaluated. Southern yellow pine (Pinus palustris Miller) were used for deck material. Bending strength of deck units were implemented for fastener type and joist spacing (400, 600 mm). In the result, carbon steel screw into reinforced plastic connector was the best in average bending strength(Joist spacing : 400, 600 mm). In the result of bending strength for joist-width (40, 50, 70, 80 mm), the average maximum bending strength was measured when the joist spacing was 40 mm.
