  • Ondol is a traditional underfloor heating system designated as a national intangible cultural heritage of Korea. The Cultural Heritage Administration (CHA) publishes a standard specification for the repair of cultural properties, including ondol. This standard specification is used as a guide for contractors who repair ondol in the field. However, the standard specification for ondol repair has some errors and is difficult to understand in the field. This paper proposes a revision of the standard specification for ondol repair. This study found that the standard specification for ondol repair has some problems in terms of the terminology and structure of ondol. These problems were sufficient to confuse ondol repairers in the field. Therefore, this study proposes to revise the standard specification to correct these errors and make it easier for ondol repairers in the field to understand. This study is expected to help recognize and preserve ondol as a cultural property and not just as a building.

  • 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.

  • Considering that the classified items in the work section level can have an applicability when those items are being used to cost and specification information with consistency, the work section classification code should be applied as an Integrated code system. Our construction industry is using three work section classification systems for civil engineering projects, such as integrated construction information classification system, standard method of measurement and guide of project specification. And each standard construction specification is also using different work section classification systems. This study suggests a methodology to integrate the code systems in construction specifications with civil engineering standard method of measurement. And the methodology suggested in this study was applied to a web-based prototype system with practical specification codes.

  • The plater work in the standard of estimate presents a variety of construction types. However, there is a part that does not fit the change of specification standards and on-site construction status, and it was revised in 2019's standard of estimate. In this study, we analyzed in detail the factors affecting the changes in estimating standards in the plater work. There were changes in the specification standards previously presented as primary coat, secondary coat, and formal coat as well as changes in on-site construction status such as thickness according to the number of plastering. Therefore, it is analyzed that the estimating standards can be classified by the number of finishes according to the site conditions by reflecting the analysis of the specification standards and site application status, and suggesting the finishing standards according to the number of plastering.

  • In this study, we proposed a specification which is able to estimate tile uncertainty more easily and quickly and also able to maintain a confidence level when measuring tile magnitude and phase of 1-port and 2-port transmission.reflection coefficient using a VNA and attached coaxial cable probes. This proposed specification is available when it needs extra special condition of uncertainty estimation and when there is no additional standard equipment like as beadless airline or mismatch standard at the measurement institute. We compared and examined this proposed uncertainty estimation method with recommended EA specification and Agilent specification. As a result, we think that this proposed specification can be used as a reference for uncertainty estimation and calculation of VNA system, that is, a reference based on the IS0/1EC 17025 requirements.

  • Urban transit is one of the most effective ways for efficient operation and construction of an urban transit by composition system which is liked originally such as rolling-stock, power, signal and infrastructure. Urban rail transit system is running in domestic, imports major equipments from advanced countries and setup for maintenance. But it takes long time because it does each organizations and lines. Also, signal, power and track system apply different standard by each construction organizations it causes an increasing construction of cost accordingly it desperately needs a systematic countermeasure. Therefore standard specification of urban transit have been establishing and operatingfor efficient operation of urban transit and base technology security that is populace ride to become a base of state economy. After track, power and signal system will be announced. Standard specification become more, the importance of administrationof standards is emphasized more. Specification administrator’s the importance which use a computing support tool recently in railroad part in embossed and is predicted to be more such forward. Therefore we propose the effective method of management with track, power signal system by constructed data-base system.
