국내 건설기준은 설계기준과 시방서로 구성되어 있다. 이는 현재 국토교통전자정보관에서 서비스하고 있지만 DB가 아닌 파일 형식으로 서비스하고 있으며 이력관리 및 참조기능이 미비하는 등 활용성과 범용성이 미흡한 문제점이 있다. 이러한 문제점은 국가건설기준을 현업에 활용 가능한 파일포맷으로 변환하기 어려우며, 기준간 상호 참조, 제 개정 이력관리 등을 어렵게 한다. 따라서 본 연구에서는 국내외 유관 시스템 분석 및 시사점 도출, 현 시스템의 문제점 및 개발방향 제시, 요구기능별 세부 구현방안 제시, 코드 관리시스템 설계 및 구현 등의 절차를 통해 국가건설기준 코드 관리시스템을 개발하였다. 개발한 시스템은 국가건설기준 작성 시스템, 국가건설기준 서비스 시스템, 국가건설기준 정비 업무 시스템, 국가건설기준 포털 부가시스템 등 총 네 개의 세부 시스템으로 구성하였다. 세부 기능으로는 국가건설기준의 표준 포맷으로 변환 기능, 항목별 개정 이력관리 기능, 세부 항목간 참조기능, 기준을 작업 가능한 형태로 변환 기능, 국가건설기준위원회 구성 운영기능, 기타 포털 시스템으로써 갖춰야 할 기능 등 총 20개로 구성하였다. 본 연구의 결과물을 활용한다면 복잡 다양한 국가건설기준의 제 개정 운영 및 이력관리를 용이하게 하여 사용자 편의를 증진시킬 수 있을 것이며, 국가건설기준 제 개정 운영을 효과적으로 지원하여 중복 상충 최소화 등을 통한 수준 높은 국가건설기준을 도출할 것이라 예상된다.

Disposable protective coveralls that cover the entire face and body are essential for operations in contaminative or dangerous environments. This research studied disposable protective coveralls on Korean market in order to improve the products that agricultural workers wear. We investigated the size specifications of 22 disposable protective coverall products sold in Korean markets and analyzed how well the size specifications cover Koreans' sizes by comparing and analyzing the size specifications with Korean body measurements and Korean standards for protective clothing. We analyzed the consistency, regularity, and fitness to body measurements of Koreans for each size by measuring the sizes of 15 different parts for 22 products each. Current disposable protective coverall products for the Korean market are unsuitable for Korean body measurements, especially women's. It was expected that wearers would be unable to choose products that fit their bodies well just by the offered size specifications due to a lack of regularity between the measurements for each size. In this result, it was assumed that the development of KS standards and the coverall pattern that reflect the body measurements of Koreans are needed.

In this paper, we review the domestic reliability standards and its global counterparts IEC/TC 56 international reliability standards. Recently private transfers of reliability certification control tower has established in Korea. Some check points to consider regarding the control tower transfer process to the non-government organization are suggested. Also the IEC/TC 56 and its relevant reliability standards are introduced. Understanding of the IEC/TC56 system will be helpful for the time of non-government organization control tower transfer in the reliability certificate specification

Images taken from airplanes, satellites and drones have been used in various realms, and the kinds and specifications of images are enlarged gradually. Despite the importance of images on diverse applications, the quality information of the images is controlled by each agency or institute respectively without any principle, or even is neglected, because the application of standards to the final products of image is not easy in Korea. We aim to review necessities and strategies for applying international standards on image and to suggest potential issues and possibilities to make standards in action.

This paper presents a composite luminance signal processing system for NTSC, PAL and SECAM standards. Eaxh of the three standards employs its own specifications of subcarmier bandwidth and luminance signal waveform. The proposed system, compatible to the specifications of the three standard and B/W TV, implements variable freqneucy characteristics by controlling filter coefficients. The major features of the system are a luminance/chroma separation unit and an aperture compensation unit. The luminance/chroma separation unit employes a notch filter selection a trap freqneyc to atenuate unwanted color signals in luminance signal bands. The aperture compensation unit comprises two subunits, to provide clear color definition for each of the three standards: a primary compensation circuit and a variable compensation circuits. The proposed system yields a 40 dB gain from the chroma/luminance separation and a 10 dB gain from the aperture compensation unit.

Purpose: Using international specifications, this study classified international standards and automobile manufacturers' test items based on the kind of test used and determined the test order for ISO 16750. Methods: The effects of international standards' environmental factors were examined, based on the major impacts of the product and the results of product failure. Automobile manufacturers' test items were compared with the test item in the ISO 16750. A generic algorithm was then used to determine the test sequence for ISO 16750. Results: International standards and automobile manufacturers' common test items were classified. The test sequence of ISO 16750 was determined for five cases. Conclusion: Although mechanical and environmental tests share many common features, there are differences in the details of the tests. There is a common sequence of tests, but weights are allocated tests differently.

Recently, OSC (off-site construction) construction has been revitalized as a response to the decline in building quality and productivity due to lack of skilled manpower at construction sites, and PC (precast concrete) construction, a representative OSC construction, is insufficiently applied to public housing.This is the situation.In addition, in the case of general contents appearing in standard specifications, the construction standards for quality assurance remain in the 1990s and do not correspond to the current construction environment.In order to improve the quality of PC member joints, we compared and analyzed Korean and Japanese specifications to establish appropriate standards for PC construction quality control, focusing on the quality of grout used in joints.

This study investigated the typical standards of B kind of standard specification related to home and abroad forms design and compared them, and the results can be summarized as follows. In case of domestic standards, regulations on most forms design was described relatively in detail. and in case of CTEA among them, it included detailed contents of load conditions, lifting and subsidence. In case of abroad standards, the design regulations are only simply mentioned, not in detail, in ACI, CEB-FIP and BS, and JCI and JASS were similar to domestic KCI and KASS regulations. As to structural calculation in forms design regulations, most of domestic regulations included detailed matters on structural calculation, among them, CTEA shows the most detailed matters on it. On the other hand, it could be known that in case of abroad standards, most standards do not include matters on structural calculation except ACI, JCI and JASS.

Research on the "Modernized Korean traditional housing" (Hanok) has been actively studied in succeeding to Korean traditional housing and providing the public with housing that required for modernized life style. The purpose of this study is to classify work sections for Hanok specifications. This paper analyzed the concepts and characteristics of existing specifications. It was found that the absence of standard classifications is one of the causes of missing work items and mixed scopes. Also, the contents of carpentry works have low level of details. Therefore, Hanok specifications, in this study, are required to have upper level standards and to encompass traditional and new construction methods. Further research will develop standard classifications, standard codes, and automated systems of Hanok specifications for improving quality and effectiveness.

In many parts of the world, low cost housing used to be built and maintained by the governments, based on designs and detail specifications prepared by the public sector with construction carried out by contractors. Results vary due to differences in design standards, workmanship and property management, depending also on the neighbourhood's care of the estates and their pattern of usage. In the UK, where Private Finance Initiative (PFI) has been used for infrastructure projects, there have been successful cases of city estate being transformed by PFI. These PFI housing schemes involve new-build, refurbishment as well as facility management. Unlike traditional construction, which is based on prescriptive specifications, PFI housing is based on output specifications. A study has been undertaken to compare the two specification approaches as they are applied to housing estate. Results are enlightening and serve as good reference to cities such as Hong Kong SAR and Singapore, where public housing provisions have been a major concern of their citizens as the building stock gets older.
