  • This purpose of this study to analyze effect material properties have on change in QR code recognition rate according to change of materials by comparing recognition rate of color QR code. QR code applied to textile materials has the advantage of being washable and being applicable to lost child prevention goods or clothes or a person with dementia through record of information relating to the material or input of additional information, differently from QR code printed on the conventional paper. An effective method of entering QR code in textile materials is Digital Textile Printing(DTP), that facilitates printing by rapidly applying diverse information, and small quantity production. It is possible to tailor various QR codes according to use. Regarding samples to use, cotton material used in clothing products and Tyvek material recently applied to clothing and related products were selected. Reactive dyes were used for cotton, pigment was used for Tyvek, and QR code was printed with an inkjet printer by direct printing method. Printing methods and surface textures are different between cotton and Tyvek. It was revealed that consequent print results and results of recognition rate were different. Regarding color to be printed, 2015 S/S - 2017 S/S color presented by Pantone was used. Color combination affected recognition rate of color QR code. Understanding color combination, material properties and print characteristics may be helpful in increasing recognition rate of color QR code, and may contribute to usability of color QR code applied to textile materials in the future.

  • 본 연구는 석유화학 플랜트 설계, 구매 시공에 직간접적으로 많은 영향을 주는 배관자재의 관리 효율성을 높이기 위하여 자재 코드 및 자재관리 시스템의 근간이 되는 배관자재 코드 분류체계를 개선하였다. 기존 배관자재 코드 분류체계를 개선하기 위하여 내재된 문제점을 자세히 파악하고 국내외 대형 EPC 기업의 배관자재 코드 분류체계 특징을 조사하였으며, 최근 대형화, 전문화 되어가는 프로젝트의 특성을 고려하여 개선 방향을 설정하였다. 배관 자재별 특성에 맞는 코드분류체계를 정의하고, 표준 속성을 추가하고, 신규 자재 및 재질을 고려한 코드 자릿수 확장 및 계층적 분류 구조를 통하여 효율적 배관 자재관리를 위한 배관 자재 코드 분류체계의 개선 구조를 도출하였다. 개선된 배관자재 코드 분류체계를 수행중인 프로젝트에 적용한 결과, 자재 구매사양서의 재 작업률이 평균 4.98%에서 2.48%로 감소하였으며, 3차원설계에서 요구되는 배관 형상 구축 작업시간이 기존 평균 작업인원 2명이 6개월 소요 되었으나, 1명이 4개월로 67% 감소 효과를 가져왔다. 또한 피라미드 코드 구조를 통하여 전사 자재관리 시스템과 연동되어 구매, 견적 등 유관 부서에서 다양한 데이터를 축적하고 내부 경영관리 의사결정을 위한 프로젝트 분석에 활용할 수 있게 되었다.

  • Sanitary codes of retail ffod establishment of Korea, Japan, China, and America were reviewed in order to figure out the differences of the codes. The codes of Korea & Japan are similar in many aspects. The code of America regulates food safety procedures in detail and are easy to interpret. The code of China is broad and not specific in the procedures. Korean code deals with many administration affairs and Japanese code deals with food test and business. Chinese code also deals with administration and standards. American code defines 90 different terms while the codes of rest of the countries define only few terms. For sanitization American code specifies the procedures in specific terms in detail but others do not specify the procedures. For facilities, the American code specifies location, material and procedures but other codes also specify the material but the contents of the codes are not so much specific to compare with American code.

  • Because of world financial crisis, The Korea domestic construction industry has been damaged hugely on material supplying work. A current domestic material supply system can't react properly on a great rise of foreign exchange rate and raw material price, so the system has a problem which is not properly supplying material. To solve this problem, a more innovative material supply work system is seriously needed than ever. So this study wants to improve material supply system for supplying material right time, right place through applying a web-based system. Applying this, overall process of material-supply-work can be done on a web-based system for immediately understanding change of ordering and warehousing by material-supply-schedule to a domestic construction field.

  • This paper presents the development and validation methods of the FUTURE (FUel cycle analysis Tool for nUcleaR Energy) code, which was developed for a dynamic material flow evaluation and economic analysis of the nuclear fuel cycle. This code enables an evaluation of a nuclear material flow and its economy for diverse nuclear fuel cycles based on a predictable scenario. The most notable virtue of this FUTURE code, which was developed using C# and MICROSOFT SQL DBMS, is that a program user can design a nuclear fuel cycle process easily using a standard process on the canvas screen through a drag-and-drop method. From the user's point of view, this code is very easy to use thanks to its high flexibility. In addition, the new code also enables the maintenance of data integrity by constructing a database environment of the results of the nuclear fuel cycle analyses.

  • The transport of radioactive material by sea is strictly governed by the international regulatory regime which is established by both IAEA and IMO. Nonetheless, although the current regime is well established, due to catastrophic results of potential accident, it is essential to keep identifying areas where further enhancement is necessary. This paper reviews the current regulatory regime governing sea transport, such as IAEA Regulations, IMDG Code and INF Code. Then, specific requirements of the INF Code are analyzed for the purpose of identifying areas where improvement is necessary from the perspective of ships. Through this analysis, this paper identifies areas to be improved and proposes to improve the INF Code which can supplement the current regulatory regime for sea transport of radioactive material.

  • The purpose of this study is to investigate material designation in library cataloging and to suggest General Material Designation (GMD) and Specific Material Designation(SMD) in Korean. A summary of the study follows. In library cataloging, methods of indicating the type of material are : (1) color-coding, (2) media code as part of the call number, (3) material designation in physical description area or note area, (4) GMD and SMD. GMD is a term indicating the broad class of material to which a bibliographic item belongs. SMD is a term indicating the special class of material to which a bibliographic item belongs. GMD was listed in parenthesis following the title proper before AACR1975 code, but currently it is listed in square brackets after the AACR1975 code. AACR2 was the standard cataloging rule in GMD and SMD terminology. It is suggested that GMD be used in Korean for graphic material, sound recordings, drawings, microform, multimedia, videorecordings, manuscripts, photographs, slides, printed music, motion pictures, printed texts, objects, braille, cartographic materials, computer files and transparenies.

  • Reliability analysis for a proposed limit state bridge design code is performed. In order to introduce reliability concept to design code, the proposed live load model is based on truck weight survey. Test data of domestic material strengths are collected to model statistical properties of member strengths. Sample RC and PSC girder sections are designed following the safety factor format of the proposed code and compared with the current design practice. Reliability indexes are calculated and examined for material and member resistance factor formats and sample calibrations of safety factors are presented. It is concluded that the proposed code provides reasonable level of reliability compared to the international design standards.

  • 임베디드 시스템 소스코드 감정목적물의 유사성을 판단하는 경우, 제공된 소스코드가 컴파일이 가능한 상태인지, 실행이 정상적으로 되는 것인지, 하드웨어와의 인터페이스가 일치하는지 등의 확인이 되지 않은 상태로 제공되는 경우가 지속적으로 발생하고 있다. 분쟁을 제기하는 측에서는 동작의 특성이 유사하고, 나타나는 기능의 효과가 유사한 이유로 소스코드의 많은 부분이 유사할 것으로 판단하고, 감정을 요청하게 되지만, 위의 여러 가지 상황으로 유사성 분석 결과가 기대와 다르게 나타나는 가능성이 우려된다. 본 연구에서는 감정사례를 통해 소스코드의 분석 과정과 검증되지 않은 소스코드의 유사성 도출의 개선방향을 제시한다.

  • 이 연구에서는 국내 도로교 한계상태설계법에서 콘크리트부재의 설계를 위하여 적용하고 있는 재료계수의 문제점을 제기하고, 잘 정립된 최적화 과정에 의한 재료계수를 제안하였다. 신뢰도분석을 통하여 현 설계기준의 하중계수와 제안 재료계수가 목표신뢰도지수 보다 높은 신뢰도수준을 확보하고 있음을 보이고, 역신뢰도해석을 통하여 목표신뢰도지수를 잘 근사할 수 있는 하중계수를 제시하였다. 유로코드에서 제시하고 있는 기본 개념에 근거하여 신뢰도기반 하중-재료계수 결정법을 정식화하였다. 제안된 접근법이 신뢰도개념에 의하여 유도되었지만, 이 접근법에 의하여 계산된 하중-재료 계수가 목표신뢰도지수를 정확히 만족시키지 못하는 요인으로서 재료와 부재간에 존재하는 불확실성의 차이를 지적하고, 이러한 차이를 고려하지 않는 유로코드의 개념적 문제점을 제기하였다.
