  • This study focused on analyzing classification system, technique methods, quality levels of periodic amendment characteristics in planting of standard specification. Through analyzing the above and comparing with foreign case study, this study suggests the improvement directions. The results improvement directions are as follows. 1. Many kinds of new construction were set up through the amendments of Landscape Standard Specification, but there are still needs to combine some construction categories because of mismatches between upper and lower categories. 2. Although the Landscape Standard Specification was revised to be more concrete, the contents there remains an ambiguous expression. So, standard specification is needed to revise a depth of earth ball or strength of support materials and quantify collect period of topsoil and application time. In addition, standards about following supervisor's instruction should be more detailed or deleted. 3. The standard specification has not been specified despite enactment and amendments reflecting the periodical paradigm and the needs of users, so it is still needed to revise. In addition, quality levels, planting periods, size of earth ball and performance criteria of tree materials are needed to revise. Each specific classification and construction methods were made by amendments of standard specification, but some standards are not clear and concrete. Therefore, the standard specification is needed to revise the classification system, technique methods, and problem deduction of quality levels and proposal of improvement. This study will be reference material when Landscape Standard Specification is revised.

  • Various studies has tried to unveil causes of cost overrun and schedule delay in the road construction project. However, these causes need standardization due to difference by guidelines, relevant research, and facilities. Therefore, this study identifies and elaborate standard road construction cost and schedule variation factors that can be used in the planning and execution of the project. variation factors have been derived and grouped through literature review and modified and supplemented through expert interview. In addition, the connection with the relevant guidance factors is confirmed and the usability is reviewed by applying actual road construction cases. The factors suggested in this study comprehensively include factors of related guidelines and previous research, more clearly distinguish, support decision making.

  • Currently, Hydrogen compressor is maintained and managed according to the safety management regulations of the operator. But it is not based on technical standards, so it is necessary to establish based on reliability. In this paper, hydrogen compressor taxonomy by ISO 14224 standard reviewed for hydrogen compressor operated by KOGAS-Tech hydrogen vehicle refueling station to establish 9-stage taxonomy, and FMEA was conducted to establish RCM strategy specified in SAE JA1011, and 1012. It is expected that results of taxonomy and RCM strategy will be used as basic data for development of standards for verifying the performance of compressors.

  • The national R&D information of ministries which define shared information related to national R&D projects has been derived. Among them, 21 percent are code items which can provide important standards to classify information and put out S&T statistics. Therefore, it is necessary to standardize the code items that are differently defined and managed by each research management specialized organization. For this, the National Science & Technology Information System(NTIS) intends to provide a clear code standard for the national R&D information of ministries by defining the NTIS Standard Code. In this study, we also describe the classification service to manage the NTIS Standard Code, National Standard Science and Technology Classification Codes which have been used for national R&D projects's survey and analysis as a unified way.

  • 제품 개발 및 생산 관련 기술을 체계적으로 구축하고 재활용하는 것은 프로세스와 장치에 의존하는 반도체산업에서 매우 중요하다 그러나, 국내외 대부분 반도체 업체의 경우, 양적 위주로 성장해 온 나머지 정보의 생성에서부터 재활용, 폐기까지 일련의 기술 정보 관리 과정을 수작업과 종이 형태의 산출물에 의존하는 실정이다. 이런 현실은 제품 개발과 생산 기술 확보에 추가적인 리드 타임을 유발하여, 원가 및 조기 시장 선점의 부담으로 작용한다. 문제를 해결하고자 반도체 산업에 필요한 기술과 문서를 체계적으로 분류하고, 신제품 개발 정보 등, 핵심기술 정보의 대외 유출 방지를 위한 기술적, 제도적인 보안 체계를 정립하였다. 제품 개발 리드 타임 단축 및 생산성 향상을 위해 생산 시스템과 연동하여 제품, 프로세스 표준을 실시간으로 제공하는 한편, ERP와 연계된 EDMS를 설계, 구축하였다. 본 논문에서는 모델링 및 시스템을 구축하기 위한 방법과 결과를 논하고, 구축된 EDMS를 중심으로 새롭게 제시된 KMS 전략을 달성하기 위한 개념적인 모델을 제시하고자 한다.

  • This study proposes the logical data model design of a spatial data model that complies with international standards for the waterworks of underground facilities. We conduct a preliminary study related to underground spatial data standards and data models, and review the status of the existing systems. Then, we defined the conceptual design direction of underground spatial data model based on the problems and issues. Next, we defined the terminology, classification, semantic relationships of waterworks. Next, for the conceptual design of the underground spatial data model, we defined the naming criteria for all data according to the waterworks classification. In addition, a logical model is drawn and described using UML (Unified Modeling Language) diagrams. Based on the results, it is expected that the accuracy related to underground facilities data will be improved.

  • In order to enhance the safety of the international aviation industry, the International Civil Aviation Organization has recommended establishing an operational foundation for systematic and integrated collection, storage, analysis and sharing of aviation safety data. Accordingly, the Korea aviation industry also needs to comprehensively manage the safety data which generated and collected by various stakeholders related to aviation safety, and through this, it is necessary to previously identify and remove hazards that may cause accident. For more effective data management and utilization, a standard structure should be established to enable integrated management and sharing of safety data. Therefore, this study aims to propose the framework about how to manage and integrate the aviation safety data for big data-based aviation safety management and shared platform.
