This study Questioned what happens in L2 reading comprehension of the expository text, as measured by recall and inference-making abilities, when a L2 reader was induced to develop a content schema about the topic of a target text, but the structure of that schema departs from the structure of the target text Seventy-four. Korean university students read either the same version text twice (consistent condition) or two different version texts (inconsistent condition) with a three-day interval between the two readings. The results of a verification test indicate that, for those subjects with higher L2 reading proficiency, the inconsistent condition was more beneficial than the consistent condition for the inference-making task. On the other hand, for lower-level L2 readers, the consistent condition was more favorable for the recall task. It was concluded that inducing a structurally inconsistent schema through an L2 pre-reading would be beneficial only when the reader's L2 linguistic ability is proficient enough to produce necessary propositions from the pre-reading.

This paper presents the observation that negative alternative questions across languages can be formed only when negation has not been inverted (Han (1999)), and proposes to derive this fact from the effects of Focus on negation and the LF-syntax of yn-questions. Although the questions in (1) have the same components (they both contain the proposition expressed by John drank coffee or tea plus negation), they do not have the same interpretation. (1b) has either a yn-question reading or an alternative question (alt-) reading. Under, the yn-reading, the possible answers are Yes, John drank coffee or tea and No, John did not drink coeffer or tea, John didn’t drink one of them, and the possible answers are John did not drink coffee and John did not drink tea (see Karttunen (1977), Larson (1985), Higginbotham (1993) on the semantics of alt-questions). (la), on the other hand, has only the yn-reading.

In this study, an interactive programming method for robot in electronic part assembly task is proposed. Many of industrial robots are still taught and programmed by a teach pendant. The robot is guided by a human operator to the desired application locations. These motions are recorded and are later edited, within the robotic language using in the robot controller, and play back repetitively to perform robot task. This conventional teaching method is time-consuming and somewhat dangerous. In the proposed method, the operator teaches the desired locations on the image acquired through CCD camera mounted on the robot hand. The robotic language program is automatically generated and downloaded to the robot controller. This teaching process is implemented through an off-line programming software. The OLP is developed for an robotic assembly system used in this study. In order to transform the location on image coordinates into robot coordinates, a calibration process is established. The proposed teaching method is implemented and evaluated on an assembly system for soldering electronic parts on a circuit board. A six-axis articulated robot executes assembly task according to the off-line teaching in the system.

One of the controversial issues in English locative inversion (LI) construction( e. g. Under the tree sat a woman) has been the functional status of preverbal PP and postverbal NP, i.e. whether they are a subject, a complement, or filer (topic) Based on the distributional parallelisms between the PP and NP on the one hand and an ordinary subject and filler on the other this paper proposes that the PP has a dual function as a subject and filler, while the NP also has some subject properties that the PP does not have These mixed functional properties are analyzed in the theory of HPSG expecially with the versions recently developed by Sag(1997) Manning and Sag(1999) and Ginzburg and Sag(to appear). This analysis claims that the LI construction needs to satisfy two general, independent constraints head-subject- phrase and head-filler-phrase. This position suggests that the English LI construction is an instance of the peripheral phenomena whose construction specific constraint is inherited from more general core constraints.

In this paper, I propose syntactic, semantic and pragmatic restrictions on the distribution of the contrastive topic marker‘-(n)un’in Korean. A contrastive topic is associated with another focus. The association with focus is subject to syntactic islands. On the other hand, there is no syntactic restriction between a phrase attached with‘-(n)un’and a focused expression within the ‘-(n)un’phrase itself. In this area there is a semantic requirement that the alternatives generated by a focused expression be maintained up to the phrase attached with‘-(n)un’. Finally, when‘-(n)un’is used in an embedded clause, the whole sentence becomes natural when the contrastive topic introduced by‘-(n)un’and its alternative contrastive topic, which is presupposed by the contrastive topic marker, jointly constitute a more complex topic which is related to the whole context. And exclusiveness facilitates the formation of the whole complex context.

인간은 정보전달을 위하여 언어 이외에 동작, 표정과 같은 비언어적인 수단을 이용한다. 이러한 비언어적인 수단을 정확히 분석 할 수 있다면 인간과 컴퓨터간의 자연스럽고 지적인 인터페이스를 구축할 수 있게 된다. 본 논문은 별도의 센서를 부착하지 않은 단일 카메라 환경에서 손 형상을 입력정보로 사용하여 손 영역만을 분할한 후 자기 조직화 특징 지도(SOFM: Self Organized Feature Map) 신경망 알고리즘을 이용하여 손 형상을 인식함으로서 수화인식을 위한 보다 안정적이며 강인한 인식 시스템을 구현하고자 한다. 제안 방법으로는 피부색 정보를 이용하여 배경으로부터 손 영역만을 추출한 후 추출된 손 영역의 형상을 인식한다(전처리과정으로 모델이미지의 사이즈와 압축 및 컬러에 대한 정보를 정규화 시켰다). 또한 인식 효율을 높이기 위해 SOFM 신경망 알고리즘을 적용함으로서 보다 안정적으로 손 형상을 인식할 수 있게 되었으며, 손 형상 인식률에 대한 안전성과 정확성을 향상시킬 수 있었다. 그리고 인식된 손 형상의 의미를 텍스트로 보여줌으로서 사용자의 의사를 정확하게 전달할 수 있다.

PLC를 사용한 공정제어시스템의 설계에서 PLC 표준언어중 LD 언어가 가장 널리 사용되고 있다. 그러나 LD 언어는 데이터처리와 유지보수에 대한 단점이 있다. 반면에 SFC 그래픽언어는 복잡한 순차동작을 간결하게 記述할 수 있는 완벽한 방법이지만, 인터록조건을 記述하는데 문제점이 있다. 본 논문에서는 기존의 SFC 컴파일러를 사용하여 인터록을 실현하는 방법을 제시하고, 실예로서 In-Line Spin Coater에 적용하여 타당성을 확인하였다.

본 논문에서는 깊이 카메라를 이용한 사용자의 손 모양, 특히 수화를 인식하는 방법에 대해 제안한다. 손 모양 인식은 손가락 검출과 손 인식으로 크게 2가지로 나눌 수 있다. 손가락 검출을 위해 본 시스템에서는 Distance Transform을 이용하여 손의 뼈대를 검출 하고, Convex Hull을 통해 손가락을 검출하는 방법을 제안한다. 뼈대 검출은 보다 정확한 손가락을 검출할 수 있는 장점이 생긴다. 손 인식에는 손 중심과 손가락의 길이, 손의 축, 손가락의 축, 팔 중심의 위치 등을 이용하여 Decision Tree를 생성하고, 반복적 검사를 통해 인식의 오류율을 줄였다. 실험결과에서는 수화 인식이 성공적으로 잘 인식 되었다는 것을 보인다.

This study intended to determine the most appropriate POS(Part of Speech) sets for predicting prosodic boundary strength efficiently. We used 3-level POB bets which Kim(1997), one of the authors, has devised. Three POS sets differ from each other according to how much grammatical information they have: the first set has maximal syntactic and morphological information which possibly affects prosodic phrasing, and the third set has minimal one. We hand-labelled 150 sentences using each of three POS sets and conducted perception test. Based on the results of the test, stochastic language modeling method was used to predict prosodic boundary strength. The results showed that the use of each POS set led to not too much different efficiency in the prediction, but the second set was a little more efficient than the other two. As far as the complexity in stochastic language modeling is concerned, however, the third set may be also preferable.

This paper proposes that concession should be analysed in terms of inferences based on the likelihood of event occurrence and that an alternative set of events should be presupposed in such inferences. In order to give an empirical content to this proposal this paper discusses the pragmatic aspects of the English word even and the Korean morpheme -lafo and claims that the notion of likelihood is the basis of the pragmatic inference of concession and the quasi-universal quantification erect. It is also claimed that unexpectedness, which is conceptually tied to concession, on the other hand, pertains to the same kind of pragmatic inference but presupposes the existence of an alternative set of individuals instead of an alternative set of situations.
