  • In this paper, we propose set-up model of silicon steel cold rolling mill. Until now, the working of Silicon Steel is operated using the look-up table value of roll force which a field operator finds by making good use of his experience. Therefore, the standardization of data and an improvement of the quality on product are very difficult. So we establish neural model using field data of various kinds of coil at each pass.

  • Fishery sea anchor is widely used for many fishing vessels. However, standardization of the dimension and terminology of the fishery sea anchor has not been achieved, reducing the reliability of the performance and safety of the fishery sea anchor. Therefore, this study researches the reality of usage of fishery sea anchor and then attempts to suggest the development direction of the standard draft as basic data. As a result of the survey on the reality of usage show that various terms were used for each part of the fishery sea anchor (including the incorrect form of non-standard words derived from Japanese) and that the production of this product in the fishery sea anchor market was concentrated on one specific manufacturer. In addition, the main specifications of the fishery sea anchor are set and manufactured based on conventional experience without standards. In the field, there was no standardized drawing for fishery sea anchor and users had low awareness of the main specifications of fishery sea anchor. Therefore, this study suggested the following regarding the fishery sea anchor: standard terms for each part including Korean and English names and standard drawing of sea anchor. It is hoped that this study will contribute to research for the standardization of fishery sea anchor, which will increase in reliability and lead to increased interest in standardization in the fishery field.

  • A radiometric correction method is developed to apply multi-temporal KOMPSAT-1 EOC satellite images for the detection of land-cover changes b\ulcorner recognizing changes in reflection pattern. Radiometric correction was carried out to eliminate the atmospheric effects that could interfere with the image properly of the satellite data acquired at different multi-times. Four invariant features of water, sand, paved road, and roofs of building are selected and a linear regression relationship among the control set images is used as a correction scheme. It is found that the utilization of panchromatic multi-temporal imagery requires the radiometric scene standardization process to correct radiometric errors that include atmospheric effects and digital image processing errors. Land-cover with specific change pattern such as paddy field is extracted by seasonal change recognition process.

  • 최근 들어, 건설현장에서의 안전사고에 대한 예방 및 신속한 대응과 함께 현장관리의 효율화를 위해서 IT와의 통합적 활용이 요구되고, 작업자의 안전 확보와 원활한 작업지시 그리고 시공의 효율성 등을 구현하기 위한 건설현장지원시스템의 구축이 필요하다. 본 연구에서는 현재 VI-GNSS(Voice Integrated-Global Navigation Satellite System)통합기술 기반의 지하구조물 건설현장지원시스템(USFSS, Underground Structure Field Support System)구축을 위하여 시스템 간 정보 전송 및 관리를 위해 데이터 및 음성정보에 대한 정보 표준화와 네트워크 아키텍쳐를 설계하였다. 이를 통하여 구축된 시스템별 정보의 안정성 테스트에서 데이터 전송 안정성의 경우 지하구조물 내 작업자 및 이동차량 시스템과 현장서버시스템에서는 각각 약 98%, 현장서버시스템과 관제시스템사이의 안정성은 약 100%를 확보할 수 있었다. 또한, 음성 전송 안정성 테스트에서 FRS(Family Radio Station)무선시스템을 통한 지하구조물 건설현장과 현장 주변 현장사무소까지의 음성 전송의 경우 1km 거리 구간을 기준으로 약 99%의 신뢰성을 확보하였다.

  • Gyeonggi science high school for the gifted (GSHS) installed 60cm telescope, which is waiting for student observers. It is essential to understand the characteristics of the photometric system, consisting of telescope, filter, and CCD, to get reliable data. CCD images of SA98 Landolt standard field and M67 were obtained on 19th March 2020. The images of each field were combined by filters, i.e., we ignored the monochromatic atmospheric extinction since the photometric objects themselves are standard stars. 24 standard stars in SA98 field and 12 standard stars in M67 were used to derive the tentative transformation equation between our bv photometric system and Johnson BV photometric system. In this poster, we present the preliminary standardization result for Johnson BV photometric system in GSHS 60cm telescope. The reproductivity is discussed by comparing color coefficients of two fields. We plan to extend this process to Johnsons-Cousins BVRI photometric system and narrow-band filters for flux calibration.

  • 본 연구에서는 현재까지 진행되어온 표준화 작업의 결과물인 GIS 국가표준 및 단체표준의 활용현황을 분석하여 표준화 과정의 문제점을 밝히고 이와 같은 문제점을 해결하기 위한 표준화 추진방안을 제시하였다. 이를 위하여 본 연구에서는 GIS 표준의 활용성을 국제표준 및 국내표준에 대해 분석하였으며 향후 국가표준화가 시급한 국제표준들에 관하여서도 조사하였다. 아울러 이와 같은 분석결과를 토대로 본 연구에서는 표준화 대상의 선정 및 우선순위를 도출하고 표준 활용 활성화 방안을 제시하여 향후 표준화활동이 전체적인 국가GIS발전에 밑거름이 될 수 있는 추진전략을 제시하였다. 현재 GIS 표준의 활용범위는 극히 제한적이라고 할 수 있다. 그러나 많은 전문가들 및 사업추진담당자들은 표준이 향후 중요한 역할을 할 것이라는 점을 잘 인식하고 있다. 따라서 국가적인 차원에서 지속적인 수요조사를 통해 현장에서 중요하게 사용되는 표준들을 중심으로 표준화 우선순위를 설정하고 체계적으로 표준화 작업을 수행한다면 보다 효율적인 표준화가 추진될 수 있을 것이며 표준의 활용도도 높아질 수 있을 것으로 생각된다. 지금까지 우리나라에서는 주로 데이터 구축 측면의 표준에 많은 노력을 기울여 온 것이 사실이다. 그러나 표준의 궁극적인 목표는 상호운용성의 확보를 통한 효율성의 제고라는 점을 생각했을 때 향후 지리정보 서비스관련 표준의 중요성이 한층 높아질 것으로 생각되므로 이 부분의 표준화 작업에 보다 많은 관심을 기울일 필요가 있을 것으로 보인다.

  • 유비쿼터스(Ubiquitous) 정보화 사회에서는 공간정보에 대한 실제적인 모습과 정확한 위치정보가 요구되고 있다. 공간정보의 대국민 서비스가 이뤄지기 위해서는 공간정보의 표준화가 필요하다. 국제표준(International Standard)은 세계 각국에서의 각종 규격 기술 용어 등의 호환성을 확보하고 상호교역을 촉진시키기 위해 일정한 기준과 표준 형태를 국제 간 합의를 통해 규정해 놓은 것을 말한다. 국제표준안은 국제표준화기구(ISO : International Organization for Standardization)에서 제정하고, 지리정보분야의 국제 표준안은 ISO TC(Technical Committee) 211 에서 담당한다. ISO TC 211에서 추진 중인 토지행정도메인 모델(LADM : Land Administration Domain Model)은 토지와 관련된 행정 법, 공간 측량 등의 국제표준화를 제정하여 각 국가의 토지 관련 시스템과 데이터를 효율적으로 관리하고자한다. 본 논문에서는 토지행정도메인 모델 부분 중에서 측량과 관련된 표준화 진행 상황과 내용을 소개하고 국내지적정보모델을 비교 연구하였다.

  • Objectives : Moxibustion-related standards have been established by organizations such as the International Organization for Standardization (ISO) and the Korean Standards Association (KSA), among others. Methods : We summarized moxibustion-related standards that have been published by ISO and KSA. Results : Technical Committees 249 (ISO/TC 249), which was established in 2009, has been established moxibustion devices standards in working group (WG) 4. International standards have been established for moxibustion devices, smokeless moxibustion devices, moxa floss quality, and electric heating moxibustion equipment. Work on international standards for infrared moxibustion-like instruments and moxibustion device terminology is currently in progress. Conclusions : Korea has taken a central role establishing international standards for a wide range of moxibustion devices, supported by fundamental research data in this field. To continue its influence in establishing these international standards, further studies providing the basis for moxibustion device standardization are required.

  • In this study, a neural network algorithm through a data standardization method was developed to discriminate the phase-shifted partial discharge(PD) patterns such as a $\phi$-q-n pattern. Considering the PD measurement in the field, it is not so easy to acquire absolute phase angles of PD pulses. As a consequence, one of the significant problems to be solved in applying the neural network algorithm to practical systems is to develop a method that can discriminate phase-shifted $\phi$-q-n patterns. Therefore, authors established a new method which could convert phase-shifted $\phi$-q-n patterns to a standardized $\phi$-q-n pattern which was not influenced by phase shifting. This new standardization method improved the recognition performance of a neural network for the phase-shifted $\phi$-q-n patterns considerably.

  • In the Korean domestic construction field, there are a lot of problems related to construction information exchange and sharing owing to the absence of construction drawing information exchange standard. To remedy the aforementioned inefficiency effectively, it is necessary to apply the STEP standard which is known as an international standard for achieving the establishment of Construction CALS. This study focus on suggesting a methodology to activate the STEP based construction drawing information exchange standard to the current construction drawing information exchanging and sharing practice. In this paper, the domestic and foreign standardization projects related to the construction drawing information have been investigated and analyzed. In addition, a methodology of applying and activating the STEP standard has been suggested. Finally, a verification and certification methodology for applying the CALS/EC construction drawing information exchange standard(STEP) have been suggested.
