최근 정보통신 산업에서 일어나고 있는 기술 및 제품 경쟁은 표준화 경쟁이라고 해도 과언이 아닐 정도로 표준 획득은 시장을 선점하기 위하여 핵심 요소로 정보통신기술 변화의 흐름은 표준화를 지향하고 있다. 더욱이 WTO TBT(Technical Barries to Trade)의 발효는 범세계적으로 하나의 표준을 지향해 나아감에 따라 국제표준(Global Standards)의 중요성은 크게 증대되고 있다. 이에 기업은 물론 각 국가는 표준을 핵심 전략으로 인식하고, 다양한 전략적 접근을 통하여 시장선점 나아가 표준획득을 위해 치열한 경쟁을 하고 있다. 본 고에서는 게임이론 중 상대 경기자의 유형(type)을 알 수 없는 동적 불비정보게임(Dynamic Incomplete Information Game)을 이용하여, 정보통신 산업 내 먼저 네트워크를 형성한 선도기업과 이에 대하여 선도기업의 기술과의 호환을 추구하고자 진입한 추종기업간의 경쟁을 분석하고, 이를 통하여 선도기업과 추종기업 간 표준화 경쟁에 있어서 최선의 경쟁 전략을 분석해 보고자 한다.

PURPOSE. Accurate information is essential in dentistry. The image information of missing teeth is used in optically based medical equipment in prosthodontic treatment. To evaluate oral scanners, the standardized model was examined from cases of image recognition errors of linear discriminant analysis (LDA), and a model that combines the variables with reference to ISO 12836:2015 was designed. MATERIALS AND METHODS. The basic model was fabricated by applying 4 factors to the tooth profile (chamfer, groove, curve, and square) and the bottom surface. Photo-type and video-type scanners were used to analyze 3D images after image capture. The scans were performed several times according to the prescribed sequence to distinguish the model from the one that did not form, and the results confirmed it to be the best. RESULTS. In the case of the initial basic model, a 3D shape could not be obtained by scanning even if several shots were taken. Subsequently, the recognition rate of the image was improved with every variable factor, and the difference depends on the tooth profile and the pattern of the floor surface. CONCLUSION. Based on the recognition error of the LDA, the recognition rate decreases when the model has a similar pattern. Therefore, to obtain the accurate 3D data, the difference of each class needs to be provided when developing a standardized model.

Around the world, there is an increasing interest in Digital Twin cities. Although geospatial data is critical for building a digital twin city, currently-established spatial data cannot be used directly for its implementation. Integration of geospatial data is vital in order to construct and simulate the virtual space. Existing studies for data integration have focused on data transformation. The conversion method is fundamental and convenient, but the information loss during this process remains a limitation. With this, standardization of the data model is an approach to solve the integration problem while hurdling conversion limitations. However, the standardization within indoor space data models is still insufficient compared to 3D building and city models. Therefore, in this study, we present a comparative analysis of data models commonly used in indoor space modeling as a basis for establishing a generic indoor space feature model. By comparing five models of IFC (Industry Foundation Classes), CityGML (City Geographic Markup Language), AIIM (ArcGIS Indoors Information Model), IMDF (Indoor Mapping Data Format), and OmniClass, we identify essential elements for modeling indoor space and the feature classes commonly included in the models. The proposed generic model can serve as a basis for developing further indoor feature models through specifying minimum required structure and feature classes.

Interlocking software used in the electronic interlocking has been implemented through the structured approach until now. But there was the demerit that interlocking software has some problem in the standardization and the maintenance because of the limit in structured approach. Object-Oriented method overcoming this demerit was specified in the design step and the analysis step. There were object model, dynamic model and functional model in the analysis step and there were also two steps which were system design and object design in the design step. In this paper, Interlocking software was designed using Object-Oriented method to improve the standardization and the maintenance of the electronic interlocking. The electronic interlocking was analyzed with object modeling, dynamic modeling and functional modeling.

Distribution systems for operating the various systems should be operated organically. Distribution systems for organic operations extend the functionality of the system and system integration for the extension is doing. However, in systems integration for each unique non-standard definition of linkage and exchange systems are used. Non-standard definition of a unique linkage and exchange systems in the maintenance and expansion will result in many negative results. To solve these problems, the system and the exchange of information about the links between systems should define standards. IEC (International Electrotechnical Commission) power to solve these problems in the field of the Common Information Model (Common Information Model, CIM) standard (IEC61970, IEC61968) is defined as the transmission and distribution system integration and standardization for the exchange of information. In this paper, standardized system for building CIM-based distribution automation system should describe the process of building. In addition, the process of establishing a common information model needed (CIM) defined and associated services for a defined set of models is proposed in the standardization process.

We derive priority decision making on healthcare service technology standardization in the home network through the decision support process with industry professionals. We configured a research group with 4 industrial areas including Industry, Academic, Research Institution and Medical Institution. And we also applied AHP methodology for the priority decision making. The research group decides an evaluation criteria which are consisted of marketability, technology, ripple effect, strategy for national policies in order to make a priority for healthcare service on a home network. And it is also decided 7 fields and 24 sub-fields, technically. In order to make a priority for the standardization, we use an AHP methodology, that is more objective and feasible, as a decision tool. After two-phase survey that consists of paper survey and face to face meeting, we get a conclusion that home healthcare content is at the top and then wireless home network follows it.

Railroad geotechnical information management system was developed by using Web GIS and DB in this study. The standardization of railroad geotechnical information is progressed by classifying three groups as like basic informations, vibration informations along railway lines and design drawings. The basic informations consisted of basic and dynamic properties of soils, geophysical exploration and seismic survey/exploration. And the specification for 'human exposure to whole-body vibration' was adopted to construct the vibration informations along railway lines. The informations as like drawings and photographs were saved by changing to graphic files in the standardization of design drawings. In the case of standardization of geographical information, the topographical maps(NGIS, 1:5000) were primarily used as digital maps. Another digital maps(KRRI, 1:5000) and their geographical DB based on NGI code system were added on this maps. The standardized informations were used to construct their database. And railroad information management system was developed using Entity-Relation(ER) model which had a good feasibility for expansion and transition to other system in designing stage of database. This system consisted of layer selection, search and analysis of geotechnical informations and Zeus DB was adopted for GIS operating and user interface. This system could be a good tool for saving, searching and analyzing the geotechnical and geophysical informations. These DB systems would offered the basic informations to plans, design and construction of railroad lines etc. in practical use.

기업은 자사의 제품과 기술의 상호운용성을 확보하기 위하여 연구개발과정에서 표준기술을 적용하게 되는데, 이 과정에서 다양한 종류의 장애요인이 발생하게 되며, 활발한 표준화 활동을 통해 이를 극복하려고 한다. 연구개발과정에서 기업의 장애요인과 장애 극복전략 간의 연구는 다양하게 진행되어 왔으나 표준화 과정에서의 장애요인과 장애 극복전략에 관한 연구는 미흡한 상태이며, 표준화와 관련된 장애요인의 유형과 기업의 장애 극복활동에 대한 유형에 대해서도 부족한 상황이다. 이에 본 연구에서는 기업이 표준화 관련 장애요인의 유형을 도출하고, 이러한 장애요인들이 기업의 표준화 활동에 어떠한 영향을 미치는지에 대해 살펴보고자 하였다. 분석을 위해서 한국표준협회가 국내의 전기전자 정보통신 분야에 종사하는 기업을 대상으로 조사하였던 '국내표준실태조사'의 자료를 활용하였으며, 표준관련 장애사항과 필요성 그리고 표준화활동간 관계는 구조방정식 모형을 통하여 검증하였다. 분석결과에 의하면, 표준관련 장애사항은 표준화 활동에 일정한 영향을 미치고, 표준의 필요성에 의한 매개효과가 있는 것으로 조사됨에 따라 많은 기업들이 표준활동에 의한 장애사항이 발생하게 되면 이를 극복하기 위해 다양한 노력들을 수행하고 있다는 것을 알 수 있었다. 따라서 기업은 장애사항을 극복하기 위한 전략적 행동을 스스로 수행함으로써 표준화 활동은 활발해지고 표준관련 연구개발로 인해 발생하는 장애요인들은 감소되는 선순환 구조를 구축하게 될 것으로 판단된다.
