  • An automatic design method of behaviors in behavior-based robotics is proposed. With this method, a robot can design its behaviors by itself without aids of human designer. Automating design procedure of behaviors can make the human designer free from somewhat tedious endeavor that requires to predict all possible situations in which the robot will work and to design a suitable behavior for each situation. A simple reinforcement learning strategy is the main frame of this method and the key parameter of the learning process is significant change of reward value. A successful application to mobile robot navigation is reported too.

  • The purpose of this study is to develop a automation for decision of the optimum stories in apartment buildings in order to assure the solar access right for neighboring areas. Compared to the results of the optimum stories by manual process through applying a legal case over solar access right, the proposed method provides more improved and expanded information by automating the computing process of decision of the optimum stories in apartment buildings. With the result of this research, it would be possible to furnish with advanced information for an amicable settlement against the civil petition and disputes, to reduce waste of the time and cost and to improve the efficiency of solar access right analysis works.

  • A fully automated cost estimation system(FACES) has been developed. Since speed, accuracy, and consistency are essential factors in automating a cost estimation, the use of computers in cost estimation system(CES) has grown rapidly in the last few years. FACES is a micro computer based cost estimation system that employs a manufacturing knowledge base. A Group Technology(GT) based part classification and coding(C&C) scheme is used to automate the process planning aspects of cost estimation. Variant process planning methods are employed to generate workstation routings from form features of the part. The system has been tested for an assembly of six machined parts. Results indicate that the system could provide a substantial improvement in accuracy, productivity, and performance over the more traditional full dialog approach to cost estimation. It also provides a good foundation for a factory automation by using a common GT based database through design to production.

  • Magnetic Flux Leakage (MFL) methods are widely employed for the nondestructive evaluation (NDE) of gas pipelines. In the application of MFL pipeline inspection technology, corrosion anomalies are detected and identified via their leakage filed due to changes in wall thickness. The gas industry is keenly interested in automating the interpretation process, because a large amount of data to be analyzed is generated for in-line inspection. This paper presents a novel approach to the tasks of data segmentation, feature extraction and depth estimation from gas pipelines. Also, we will show that the proposed method successfully identifying artificial defects.

  • The use of Box-Jenkins technique is still very limited due to the high level of knowledge required in comprehending the technique and the cumbersome iterative procedure which requires a large amount of cost and time. This paper proposes a method of automating the univariate Box-Jekins modelling to overcome the limitations of subjective identification in iterative procedure by using Variate Difference method, D-statistic and Pattern Recognition algorithm combined with Akaike's Information Criterion. The results of the application to real data show that the average performance of automatic modelling procedure is better or not worse, at least, than those of the existing models which have been manually set up and reported in the literature.

  • In order to design an FMS(Flexible Manufacturing System), an effective design tool is necessary for selecting and anlayzing the complex interacting factors of a manufacturing system. Considering most of the previous researches have been focused on evaluating the designed FMS, development of an integrated FMS designing system is needed for performing the design task such as machine selection and layout determination as well as the evaluation task of the designed FMS. In this paper, we developed a prototype of such a system called the intelligent FMS designer based on the techniques of Expert System and Simulation. By using this designing system, possible design alternatives can be analyzed and appropriate manufacturing capacity can be estimated at the designing stage. Various operating characteristics of the designed FMS can be also predicted before it is implemented. Eventually a suitable design alternative can be provided with cost details within relatively short time period. To demonstrate the performance and effectiveness of the designer, a simple example is tested. The results show a great potential for automating design processes of an FMS.

  • XML은 W3C 표준으로 채택된 이후로 많은 어플리케이션에서 데이터를 표현하는 방법으로 사용되고 있다. XML문서는 특정 어플리케이션에 종속적이기 때문에 XSLT를 이용하여 변환한 뒤 사용하게 된다. 그러나 변환에는 많은 노력, 시간과 비용이 소요되기 때문에 이를 자동으로 변환하는 시스템을 구축하는 것이 최선의 방법이다. 이를 위해서 XTGen이나 XSLT 스크립트 시스템이 기존에 제안되었지만 사용자가 엘리먼트간의 관계를 수동으로 처리하는 방식이거나 변환 문서간 단말 노드의 1:1 매칭이라는 제약과 대규모 변환에 어려움이 있다. 본 논문은 JAWS를 이용한 엘리먼트간의 의미 관계 분석과 DTD의 구조를 분석하여 XSLT를 생성함으로써 기존 시스템들의 단점을 보완하고 더 높은 정확성을 보장한다는 장점을 가지고 있다. 본 논문에서 제안하는 시스템은 XML 문서를 변환하기 위한 XSLT를 자동으로 생성하여 XML 문서를 변환하는 모든 과정을 자동화 함으로써 문서 변환에 따르는 비용의 절감할 수 있을 것으로 기대된다.

  • In this paper, we investigate the relationship between the use of different media and customer satisfaction in help desk service. Different dimensions of customer satisfaction were derived based on SERVQUAL : reliability, empathy, assurance, tangibles, and responsiveness. The results support our hypotheses that use of conventional media (face-to-face and telephone) is related to help desk satisfaction through reliability and empathy and electronic media (e-mali and internet) users show higher satisfaction in tangibles and assurance. Also, hybrid media users (multi-media users by task) show a higher level of satisfaction in reliability and responsibility. The results suggest that automating help desks should be considered as a way to provide more options to end-users.

  • Fish schooling or group moving in cyber underwater is a part of beautiful and familiar ecosystem. It is not so easy to present the behavior of fish crowd naturally as a computer animation. Thanks to development of computer graphics in entertainment industry, the numbers of digital films and animations is increased and the scenes of numerous crowd are shown to us. Though there are many studies on the techniques to process the behavior of crowd effectively and the developments of crowd behavioral systems, there is not enough study on the development for an efficient crowd behavioral simulator. In this' paper, we smartly present the types offish behavior in cyber underwater and make up for the weak points of time and cost. We develop the fish schooling behavior simulator for the contents of cyber underwater, automating fish behavioral types realistically and efficiently.
