  • 작업 기억내에서의 통사처리과정을 살펴보기 위해 생략어를 포함하는 네가지 유형의 대등 연결문을 마지작 단어 읽기 과제를 통해 비교하였다. 특히 통사과정에 관한 설명으로 제시되는, 근접 가설, 작업 기억 가설, 최근 필러 이용 가설의 상대적 설명의 효율성을 검증하고자 하였다. 실험 결과는, 주어가 공통논항인, 표준 어순의 연결문이 다른 세 유형의 연결문보다 이해 시간이 빨랐다. 이 결과는 어느 한 가설로는 설명될 수 없으며, 대안적인 설명으로 작업 기억내에서 이용 가능한 여러 정보의 상호 제약에 의해 이루어짐을 논의 했다.

  • In this study, the method of multiple working hypotheses (MMWH) as a method of earth scientific inquiry was applied in a context of abductive reasoning about the formation of a rock with a specific structure, and the characteristics of MMWH revealed in the reasoning process were explored. Participants were 31 senior undergraduate students enrolled in a course in a university of education. As part of the course, the participants performed abductive inquiry with multiple working hypotheses about the formation of a rock. The students were asked to record both the processes and results of their reasoning in sketchbooks. The content of the students' sketchbook reports was analyzed according to the principle of analytic induction. Results demonstrated four assertions. First, the participants' working hypotheses were suggested in the use of resource models, and the adaption of the resource models often occurred in this process. Second, the perceptual properties of evidence influenced the activation of the resource models. Third, the kinds of observed evidence and the different interpretations of evidence resulted into different judgments on working hypotheses. Fourth, sometimes new hypotheses were generated by the combination of alternative hypotheses. Implications of these findings for earth science education and relevant research were discussed.

  • As transmission line is installed by manual operation, it is necessary to scheme the automatic system for stringing transmission wire. For this necessity, the objective of this paper is developed automatic control system for a stringing of transmission wire. In this paper, transmission wire with suspended pattern and ac servo motor for torque generating are modeled. On the basis of wire model, algorithms to determine the reference tension is presented, so as the dip of transmission wire is keep constancy. The control scheme is proposed by the ac servo motor for torque generation and a load cell for a detected tension of transmission wire and implemented. We experimentally show that the performance of the tension response is satisfactory. And also proposed scheme verified the utilities for tension control of transmission wire.

  • In this paper, an approach to designing controllers for the tension/movement control of working robot to install a stringing wire cable is presented. To design a controller, when the robot moves a certain distance maintaining constant tension, the dynamic model of a stringing wire cable which considers effects of weights according to changing lengths is presented. Also the tension at startup of the working robot is studied by numerical analysis which is based on the equation of the dynamic wire model. From the dynamic model for a stringing wire cable, working robot for tension/movement control is suggested and designed a feedforward controller with a accelerator gain to suppress a mutual interference of the both tasks of tension/movement control. Depending on the operating conditions of the working robot, the effectiveness of the suggested system has been verified by the simulation and experimental results.

  • A construction temporary work is main process and importance trade section. It has many works and facilities such as temporary transfer equipments which tower crane, and lift, and architectural temporary facilities which temporary office, temporary warehouse, and site test laboratory, and construction temporary equipments which scaffoldings, work plates, construction supports, and forms to set and to use in under construction and to remove in the end. A technology system of construction temporary has very low availability of field works and needs improvements in Korea as construction site has a quick response about new requirements. This study is organized existing technology systems and new technologies for field works, and developed breakdown structure of construction temporary technologies to be a basic of temporary technologies as review with site managers. For this, it will improve to be a knowledge and information system as a research of a performance and an availability about a construction temporary technology index.

  • The purpose of this study is to present a systemized flow of temporary facility(TF) planning information. The current TF planning tends to be established by subjective decision making of field workers. Therefore TF planning needs more systemized information flow to provide a reliable schedule. The study was implemented through interview with experts for reliable TF planning. The main contents of the study are as follows; 1) TF planning process model(IDEF0) are established. 2) Various information flow diagrams proposed to support TF planning decision-making. The study recommends that, as a future research, the computer system be developed for application of the information flow.

  • Demolition is mort dangerous than construction and causes a lot of harmful environmental factors. But temporary fences used on demolition sites cannot play out their roles of blocking harmful environmental factors or securing stability and work space. They only block the view from the outside. This study begins with the possibility that the temporary fence can be installed prior to demolition. As a preceding step. we performed research on the actual conditions of using it. We then realized that it can be installed according to our research plan. First, we focused on actualizing the integration of temporary fences for demolition and construction. Here are the results of this study. First, we need to grasp the limiting factors of integration. Second, we ought to revise the Korean Architecture Standard Specification. Third, we should prepare against damage and transformation of fences. Finally, we can expect to reduce harmful environmental factors, cut down expenses, improve the working environment and raise the image of demolition by the integration of these fences.
