Object-oriented programming goes on increasing in many areas, as its advantages of flexibility and ease of maintenance have been recognized. As in usual programmings, the productivity and flexibility of CACSD package can be improved by adopting object-oriented programmin. This paper describes our efforts to implement an OO-CACSD(Object Oriented CACSD) package for control system design and simulation. Since the proposed OO-CACSD is based on the modularity, portability, reuseability, and matrix-oriented data structure, a control system can be not only modeled and simulated but also maintained easily.

This paper describes the features of a transmission line and a wiring, and a design rule based on a demanded condition for a wiring. Like as the simulation of a circuit, by tracking the wiring path among parts that are disposed on PCB, we analyze the feature of the corresponding wiring using the design formula and rule. We implement a signal integrity simulator, which is capable of electrical and electronic simulation for the feature of a wiring signal and the corresponding signal, and the results are demonstrated.

Home-service robots need to have sufficient spatial information about the surroundings for interacting with human intelligently and performing services efficiently. It is very important to investigate the efficient interaction style that supports map building task through human-robot collaboration. We first analyzed map building task with a cleaning robot and drew 4 design factors and tentative solutions, including map building procedure (task-preferred procedure/space- preferred procedure), LCD display installation (robot/robot+remote control), navigation method (push type/pull type), feedback modality(GUI/GUI+TTS). The design factors and tentative solutions were defined as independent variables and levels. This research investigated how those variables affect to the human task performance and behavior in map building tast. 8 kinds of experiment prototypes were built and usability test among 16 house wives was conducted for acquiring empirical data. As the experiment result, in terms of map building procedure, space-preferred procedure indicated better task performance than task-proffered procedure as we expected. For the LCD display installation factor, remote control with LCD display indicated higher task performance and subjective satisfaction. In robot navigation method, it was very difficult to find a significant difference between push type and pull type which contrary to our expectation. In fact, push type indicated higher subjective satisfaction. Also in feedback modality, we have acquired negative feedback an additional TTS operation guidance. It seems that robot's autonomy before achieving spatial information is rudiment condition which means users are just interacting with a mobile appliance. Thus they prefer remote-control-based interaction style in robot map building process as they used in traditional appliance control.

웹 디자인 과정에 있어서 기존의 웹사이트들의 컨텐츠 정보뿐만 아니라 인터페이스를 기능적으로 이루고 있는 구조요소들에 관한 데이터 수집의 필요성이 요구된다. 그럼에도 불구하고 홈페이지 디자인에 있어 specification 수립을 위한 참고자료로써 또는 사용성 평가를 위한 자료로써 이런 종류의 데이터 베이스는 방대한 양의 인터넷 정보에 비해 미미한 편이다. (중략)

The use of service robots, particularly guide robots, is becoming increasingly prevalent in public institutions. However, there has been limited research into the interactions between users and guide robots. To explore the customer experience with the guidance robot, we selected 'QI', which has been meeting customers for the longest time, and collected all reviews since the service was launched in public institutions. By using text mining techniques, we identified the main keywords and user experience factors and examined factors that hinder user experience. As a result, the guide robot's functionality, appearance, interaction methods, and role as a cultural commentator and helper were key factors that influenced the user experience. After identifying hindrance factors, we suggested solutions such as improved interaction design, multimodal interface service design, and content development. This study contributes to the understanding of user experience with guide robots and provides practical suggestions for improvement.

The purpose of this study is analyzing the preference of young children for the outward appearance of a teacher-aided humanoid robot. The subjects of this study were 180 kindergarten children who were 4 years old. Ninety five children among the subjects were male, and 85 children were female. The instrument used for this study consisted of 15 questions that involved 3 domains; figure, face, and practical use of robot. The major findings of the study were as follows: First, young children preferred a smooth and intimate robot, and one that had a similar size to them. Second, young children preferred a more characteristic face with big eyes. Third, young children preferred a robot which had a contoured body Fourth, young children preferred a robot which had two legs or tank wheels. Fifth, young children preferred a robot that could play with them and be manipulated by them.
