It is accomplished on the practical usage for STEP in enterprise. But they has feeble grasp of STEP, therfore it is hard to apply. That is due to take a negative policy with the lack of advertising and understanding, most of studies are going on a studentlike attitude rather than the practical usage or implementation, so they don't know exactly what is STEP, and how can they apply to their own enterprise. This paper aimed to present more detail understanding of STEP usage and practical usage of STEP data in enterprise. We describe EXPRESS that is description method of STEP, four ways of implementation method, and introduce to using ST-Developer and ST-Oracle by STEP Tools Inc. for more detail understand of STEP. Thereafter we propose practical usage of STEP with CAD systems and PDM systems on the knowledge of previous study, and propose total system implementation image on STEP data in enterprise, finally discuss conclusion and luther study issues.

In this paper, we proposed a new practical implementation method of the lattice transversal joint (LTJ) adaptive filter using speech codec's information. And it was applied to the adaptive echo cancellation problem to verify the efficiency of the proposed method. Realtime implementation of the LTJ adaptive filter is very difficult due to high computational complexity for the filter coefficients compensation. However, in case of using speech codec, complexity can be reduced since linear predictive coding (LPC) coefficients are updated each frame or sub-frame instead of every sample. Furthermore, LPC coefficients can be acquired from speech decoder and transformed to the reflection coefficients. Therefore, the computational complexity for updates of the reflection coefficients can be reduced. The effectiveness of the proposed LTJ adaptive filter was verified by the experiments about convergence and tracking performance of the adaptive echo canceller.

Recently, the demand on the practical application of life-cycle cost effective design and rehabilitation of bridges is rapidly growing in civil engineering practice. However, in spite of impressive progress in the researches on the Life-Cycle Cost (LCC), the most researches have only focused on the theoretical point but did not fully incorporate the critical issues for the practical implementation. Thus, this paper is intended to suggest a systemic integrated approach to the practical application of various LCC methodologies for the design and rehabilitation of bridges, For that purpose, hierarchical definitions of LCC models are presented to categorize the approach of LCC assessment applicable for the practical implementation. And then, an integrated LCC system model is introduced with an emphasis on data uncertainty assessment and user-friendly knowledge-based database for its successful implementation. Finally, in order to demonstrate the LCC effectiveness for design and rehabilitation of real bridge structures, illustrative examples are discussed.

This paper is the part I of the full study about improved structure of fully interconnected ATM switch to develop the small sized switch element and practical implemention of switch network. This part I paper describes about proposed switch structure, performance evaluations and some of considerations to practical implementation. The proposed structure is constructed of two step buffering scheme in a filtered multiplexer. First step buffering is carried out by small sized dedicated buffers located at each input port. And second step buffering is provided by a large sized common buffer at the output port. To control bursty traffic, we use speed up factor in multiplexing and priority polling according to the levels of buffer occupancy. Proposed structure was evaluated by computer simulation with two evaluation points. One is comparision of multiplexing discipline between hub polling and priority polling. The ogher is overall which should be considered to improve the practical implementation.

This article presents the design, control, and implementation of a small quad-rotor system under the practical limitation of being cost effective for private use, such as in the cases of control education or hobbies involving radio-controlled systems. Several practical problems associated with implementing a small quad-rotor system had to be taken into account to satisfy this cost constraint. First, the size was reduced to attain better maneuverability. Second, the main control hardware was limited to an 8-bit processor such as an AVR to reduce cost. Third, the algorithms related to the control and sensing tasks were optimized to be within the computational capabilities of the available processor within one sampling time. A small quad-rotor system was ultimately implemented after satisfying all of the above practical limitations. Experimental studies were conducted to confirm the control performance and the operational abilities of the system.

Over the past few years, a number of studies have been made on web map services, which enable the GIS user to access spatial data through the web. They, however, have focused on only implementation techniques separately, such as map client implementation, map server implementation, communication between client and server, and the map data representation. Therefore, it is hard to share and practical use the spatial data, because they does not ensure interoperability in heterogeneous map servers. In this paper, we have designed and implemented the web map server with open architecture, which complies with the standard interfaces proposed by OpenGIS Consortium (OGC). In particular, we have extended the OGC’s interfaces for a map server to support one or more data sources. This paper has contributed to construction and practical use of web map services by newly proposing the method of implementation of a map server, which could be reused regardless of the types of data sources.

Purpose: This study aims to make suggestions for the implementation of the job-based dental technician practical exam. Methods: The duties of dental technicians and the recent trends in the dental technician field were defined and identified, respectively, to achieve the purpose of the current study. The practical test system of domestic and foreign national tests was comparatively analyzed to seek improvements. Additionally, the direction of the practical test to be taken in the future was investigated through a public hearing of domestic experts. Results: As a result of this study, the job site of dental technicians was recently found to be undergoing many changes, and it can be observed that related laws and the work site have already changed. Comparison of overseas test systems showed that Korea was limited to a rather small evaluation range; in general, the scope of the evaluation of the practical tests in foreign countries was widely conducted. In the results of the public hearing, opinions exist that the evaluation range of the practical test was expanded and that new subjects were needed, but the opinion on the existence of practical difficulties was mainly mentioned. Conclusion: The evaluation range of the current practical examination subjects should be expanded and the evaluation of digital dental engineering subjects should be added to proceed with the job-based practical examination. However, it seems that efforts should be made gradually through various efforts in the future due to practical difficulties.
