The fourth industrial revolution is a phenomenon where productivity is improved in each field by the convergence of IT technology and existing industries. In the dental treatment process, prosthetic treatment time is drastically shortened through AI and expert software. Oral imaging, prosthesis design, and prosthesis manufacturing are performed continuously, so the treatment can be completed in a few hours. In this paper, we introduce the research trend of multimedia technology in the prosthetic process. We also propose a new method for accelerating the fusion of surface data during the optical impression. Proposed method enables high-speed optical impression and accelerates the overall automated production process of dental prosthesis.

Information sharing and automated office in the use of PC necessitate corporate network to implement business innovation. Building an efficient network requires competent knowledge on capabilities of various LAN technologies, hardwares and softwares that have rapidly improved in terms of efficiency and cost. This paper compares capabilities of network components: communication protocol, hardware, network operation system, low cost database software and mid-range priced SQL for application development. Also this study presents a new technology on virtual LAN and a selection guide among the various options of the network components which are suitable for PC-based small-sized network in balance of efficiency with economy. In the last section of this paper, a case of small-sized network is given for illustration.

Pronunciation teaching is once again coming into the foreground of ELT. Japan is, however, lagging far behind many countries in the development of pronunciation curricula and in the actual speech performance of the Japanese learners of English. The reasons for this can be found in the prevalence of communicative methodologies unfavorable for pronunciation teaching, in the lack of trained professionals, and in the large numbers of students in Japanese foreign language classes. This paper offers a way to promote foreign language pronunciation teaching in Japan and other countries by means of employing computer and internet facilities. The paper outlines the major directions of using modem speech technologies in pronunciation classes, like EVF (electronic visual feedback) training at segmental and prosodic levels; automated error detection, testing, grading and fluency assessment. The author discusses the applicability of some specific software packages (CSLU, SUGIspeech, Multispeech, Wavesurfer, etc.) for the needs of pronunciation teaching. Finally, the author talks about the globalization of pronunciation education via internet resources, such as computer corpora and speech and pronunciation training related web pages.

An effective tool management system is one of the keys to maximizing the benefits of a computer integrated manufacturing (CIM). Tool management systems, however, are often tailored to the requirement of a highly automated system. Therefore, a different approach is needed for small and medium sized mold shops. This work deals with the implementation of tool management system for milling operations in small and medium sized CIM environment of injection mold production. In this paper, a distributed management approach is proposed for efficient tool management in relatively small machining shops in mold industry. And the design and the functions of the developed system are described.

Purpose: This study introduces the production process of dog's dental prosthesis using an automated dental prosthetics technology. The occlusal interaction of dog's dental prosthesis was observed. Methods: This study was proceeded with dog's the mandibular first molar teeth. The 3D CAD designed to 3D model specimens was observed by CAD software. and The specimens designed to 3D model specimens was observed occlusal interaction by using articulator. Results: Occlusal contact point in prosthetic specimens were observed in buccal surface. and 98% of the size of the crown is the best occlusal relationship. Conclusion: Observation of occlusal relations result to 98% of the size of the crown is the best.

This paper describes the development of an automated, hand-held sensor for the fast assessment of seafood freshness. The sensor developed here combined: an array-based chemical sensor, composed of incrementally different conducting polymer elements deposited on a small chip; a highly sensitive, custom-made electronics for the detection of very small signal changes; precise temperature control of the sensor chamber; and an on-board microcontroller for data collection, storage, automation, and analysis. The instrument was used to successfully test seafood samples with different degree of freshness and spoilage. A linear relationship between microbiological count and e-Nose signal for three different fish fillet was developed. Once the linear relationship is included into the hand-held unit software, the e-Nose signal can be used for assessment of seafood freshness without performing the microbiological count technique.

Negotiation is a process of reaching an agreement on the terms of a transaction. such as price, quantity, for two or more parties. Negotiation tries to maximize the benefits for all parties concerned. instead of using human-based negotiation. the e-commerce environment provides such an environment as adopting automated negotiation. Thus. choosing agent technology is appropriate for an automatic electronic negotiation platform. since autonomous software agents strive for the best deal on behalf of the human participants. Negotiation agents need a clear-cut definition of negotiation models or strategies. In reality, most bargaining systems embody nearly one negotiation model. In this article. we present a mobile agent negotiation system with reusable negotiation strategies that allows agents to dynamically embody a user's favorite negotiation strategy which can be preinstalled as a component in the system. We develop a prototype system, which is fully implemented in compliance with FIPA specifications, and then. describe the benefits of using the system.

CALS, being widely adopted by industry, is a strategy to share integrated digital product data through a set of standards to achieve effieciencies and competition in business. For CALS implemetation, creating a shared information system is necessary and CITIS is proposed for that. CITIS shall provide on-line access and automated exchange of all the technical information between contractor and service provider, and the function of CITIS is difined in MIL-STD-974. In this paper, regarding CITIS as a infrastructure of information for CALS, we proposed CITIS server system which comprise global data sharing software, global data management system, workflow manager, and configuration management maneger.

최근 소프트웨어가 사회에서 하는 일이 점점 더 증가함에 따라 소프트웨어의 개발비용도 함께 증가하고 있다. 소프트웨어의 개발비용 중 에러를 찾아내는 소프트웨어 테스팅이 상당한 부분을 차지하고 있는데 테스팅에 소요되는 비용 때문에 테스팅을 등한시 하는 경우가 많다. 그럼에도 불구하고 소프트웨어의 기능 추가나 변경이 이루어질 때마다 테스트를 진행하여야 소프트웨어의 에러를 최소화할 수 있다. 하지만 개발이 진행될수록 소요되는 비용이 증가하는 경우가 많아 실제 소프트웨어 개발에선 개발 기한이 다가올수록 회귀 테스트를 기피하게 된다. 본 논문에서는 이러한 문제를 해결하기 위해 소프트웨어의 개발을 진행하면서 형상관리를 통해 소프트웨어의 변경이 있을 때마다 회귀 테스트를 자동으로 수행해주는 도구를 제안한다.

Korea Railroad Research Institute(KRRI) developed the Driverless Rubber Tired Korea-AGT(Model: K-AGT) from 1999 to 2004. We have finished the safety and performance tests of K-AGT. Data obtained from this testing can be used to evaluate the growth of reliability. The most widely used traditional growth tracking model is included as IEC International standard. With the tracking model all corrective actions are incorporated during test, called test-fix-test. In the test-fix-test strategy problem modes are found during testing and corrective actions for these problems are incorporated during testing. In this paper, we demonstrated reliability analysis using growth model of driverless rubber tired K-AGT system to prove reliability of development system. Therefore, we introduce the well-known NHPP model and analyze a reliability growth using ReliaSoft's RGA software.
