  • The required level of detail in scheduling depends on the stages in the construction life-cycle. The objective of this study is to provide a Standardized Schedule Model (SSM) with an aim to facilitate the estimating of construction duration in the planning stage. The SSM modularizes work items; establishes relations between preceding and succeeding activities; and calculates approximate construction duration. The estimated duration of the SSM was compared with the detailed duration from the commercial scheduling tool using actual work activities. The difference showed to be ranged between -3.1% and +15%, which demonstrates that the SSM can be feasibly applied to the approximate estimation of construction duration.

  • This study presents the plans to derive quality items for develop the data quality standard for ensuring the quality of 3D building geospatial data in NDT(National Digital Twin). This paper is organized as follows. The first section briefly examines various factors that impact the quality of 3D geospatial data, and proposes the role and necessity of the data quality standard as a means of addressing the data errors properly and also meeting the minimum requirements of stakeholders. The second section analyzes the relationship between the standards - building data model for NDT and ISO 19157: Geospatial data quality - in order to consider directly relevant standards. Finally, we suggest three plans on developing NDT data quality standard: (1) the scope for evaluating data quality, (2) additional quality elements(geometric integrity, geometric fidelity, positional accuracy and semantic classification accuracy), and (3) NDT data quality items model based on ISO 19157. The plans reveled through the study would contribute to establish a way for the national standard on NDT data quality as well as the other standards associated with NDT over the coming years.

  • The prototypical building energy model is very useful in building energy policies, research, and technology development. A prototypical apartment model for detailed energy analysis was proposed by Seo et al. in 2014, but sufficient verification was not possible due to the lack of reliable measurement data in predicting the model's energy consumption. However, verification is now possible thanks to a recent study that analyzed the Household Energy Panel Survey (HEPS) data that is released annually by the Korea Energy Economics Institute (KEEI) and published apartment complex benchmark data. The data was used to calibrate the prototypical apartment energy model located in the central region and constructed between 1990 and 1999. The calibrated model was used to verify the other apartment building groups with respect to region and year of completion. Meteorological data for five representative cities each in the central and southern regions were used for the simulation. A majority of the 18 groups produced results that satisfied the MBE and cv(RMSE) criteria.

  • 전자거래와 관련한 많은 표준 문서 및 다양한 표준 프레임워크가 존재한다. 그러나 기업이나 개발 업체에서 전자거래 시스템 도입 또는 구축할 때, 이러한 정보를 종합적으로 참조할 수 있는 방법이 제공되지 않고 있다. 따라서 이 논문에서는 전자거래를 위해 요구되는 다양한 정보를 체계적으로 관리할 수 있는 전자거래 표준 참조 시스템을 제안한다. 이를 위하여 정보모델인 ISO/IEC 11179 메타데이터 레지스트리를 참조하여 전자거래 표준 참조 시스템을 위한 레지스트리 정보 모델을 정의하며, 정의한 정보 모델을 기반으로 표준 참조 시스템을 구현한다. 제안 시스템은 다양한 정보에 대한 체계적이고 표준화 된 관리 및 전자거래 시스템 개발자에게 보다 나은 활용의 용이성을 제공한다.

  • This paper describes and explains that the engagement level model of submarine can be used in underwater engagement simulation taking reuse, interoperability, and extension to the engineering leveled simulation into consideration. WBS(Work Break-down Structure), internal data interface, and I/O data about the engagement level model of submarine are developed. It describes the modeling method of components of submarine model as well. In this paper, the non-acoustic detection and stealth models are excluded because those models are not related to the underwater engagement, so the excluded models need to be developed in the future.

  • Standardization or standard-related study are regarded as main issues in GIS applications. Though several GIS standards and specifications have been released, there are a few actual application cases adapting those. In this study, we designed and implemented a geo-spatial information processing system with editing, storing, and disseminating functions, in which standard GIS transportation data model by TTA linked with OGC-GML, XML-based geographic features encoding standard. The system developed in this study enables us to transfer and edit transportation entities based on TTA standards to GML, importing ESRI shapefile. In web-based system, GML-based databases are transformed to SVG file, for the purpose of web publishing. TTA GIS transportation data model is used in this study, and tested; however, standard data models from other application fields also can be easily applied because this system basically provides data importing and editing functions. This system as practical tools can be utilized for applicability test of GIS standard data model and practical operation of standard specification.
