  • 소프트웨어 프로세스에 관한 표준을 각 프로젝트에서 이용하기 위해서 개발 도메인에 맞도록 테일러링하는 작업이 필요하다. 그러나 기존의 테일러링 작업은 체계적이지 않고, 개발 도메인과 방법론의 분석 없이는 불가능하며 유사한 다른 프로젝트로의 적용도 쉽지 않다. 본 논문에서는 "컴포넌트 기반 개발 개념을 활용한 테일러링 방안" 을 기반으로한 체계적인 테일러링 단계와 테스트 프로세스 생성 자동화 알고리즘을 제안하고, XML을 이용하여 구현한 “테일러링 방안의 자동화 도구, AutoTP”를 제안한다. AutoTP 사용자는 프로세스 표준이나 방법론과 도메인을 분석하는 등의 작업 없이도 특정 개발 도메인에 적합한 테스트 프로세스를 자동생성할 수 있다.

  • Lithium-ion batteries (LIBs) have attracted much interest for their high energy density (>150 mAh/g), high capacity, low self-discharge rate, and high coulombic efficiency. However, with the successful commercialization of LIBs, fire and explosion incidents are likely to increase. The thermal runaway is known as the major factor in battery-related accidents that can lead to a series of critical conditions. Considering this, recent studies have shown an increased interest in countering the safety issues associated with LIBs. Although safety standards for LIB use have recently been formulated, little attention has been paid to the safety around the manufacturing process for battery products. The present study introduces a risk assessment method suitable for assessing the safety of the LIB-manufacturing process. In the assessment method, a compensation parameter (Z-factor) is employed to correctly evaluate the process's safety on the basis of the type of material (e.g., metal anode, liquid electrolyte, solid-state electrolytes) utilized in a cell. The proposed method has been applied to an 18650 cell-manufacturing process, and three sub-processes have been identified as possibly vulnerable parts (risk index: >4). This study offers some crucial insights into the establishment of safety standards for battery-manufacturing processes.

  • 의료기기의 오작동이나 고장은 인명 피해나 큰 상해가 발생할 수 있으므로 안전성 확보가 필수적인 분야이다. 이를 위해 국제표준을 제정하고 준수하도록 하고 있지만 이들 표준은 상호의존적이고 특히, 안전성 분석 활동의 경우 시간, 노력, 비용이 많이 소요되어 표준 활동을 통합하고 커스터마이징할 필요가 있다. 따라서 본 논문에서는 의료기기 소프트웨어 개발 단계별 수행 활동과 안전성 프로세스의 활동을 통합하였다. 통합된 프로세스를 통해 하나의 프로세스로 체계적인 관리가 가능하며, STPA 기법을 기반으로 하는 프로세스 단계별로 가이드가 제공되어 안전성 활동을 효과적으로 수행할 수 있다.

  • We followed the below procedure to establish the development strategy of CITIS standard. At first, we investigated Military CITIS and Commercial CITIS to establish the concept of CITIS and examined several implemented examples. And using the previous analysis, We analyzed the structure of the functions, the technologies and the standards. To establish the development strategy of CITIS standard, we divided CITIS standards into three category, These are infrastrucure standard, data standard and process standard. In the process standard, we analyzed how we develop a formulated process and which item we select to make formulated official documents. And finally, We explained the implementation plan and extension strategy of government-enterprise and inter-enterprise CITIS respectively.

  • Heterogeneity in different Health Information Systems (HIS) processes persists to be the most demanded problem to be resolved in healthcare domain. The only way to resolve this problem is to practice health standards. One of such standards is Health Level Seven (HL7), used for the communication of medical information between healthcare systems. HL7 V3 has the aim to support all healthcare workflows. It defines series of electronic messages called interactions to support healthcare workflows. These interactions are part of the Interaction Model. Different healthcare organizations can conform to different process workflows based on their requirements. The heterogeneity in workflows results in communication blockade between sender and receiver healthcare organizations. We propose Interaction Ontology in order to cater the heterogeneity in workflows and provide process interoperability.

  • Since domestic offset print quality control depends on the experience of persons in charge rather than objective data, the standards from the data are needed for the well-organized quality management of high-quality prints. Based on the ISO standards, now the standard specifications, such as GRACoL 7, SWOP 11, SNAP, G7 in America, and EURO Color, ECI, BVDM in Europe, and Japan Color 2001, Japan Color 2004 in Japan, are employed. There exists KS for domestic standards. However, since it has been directly imported from ISO Standards, there are discrepancies in printing materials and media. Although the quality management of commercial prints has been focused and studied. For this circumstance, standards are needed for the production of prints to meet international standards. This paper aims to find out suitable ways to approach domestic printing standards using densitometric method and colorimetric method. Printing experiments on this study were performed with domestic process color inks(Cyan, Magenta, Yellow, Black) and domestic coated papers, under the same conditions as the actual commercial printing processes. In densitometric method, how to set up the optimal solid print density was studied through three tests such as the ways to match solid print density and print contrast to GRACoL standards respectively, and the way to get the highest contrast. In colorimetric method, how to get solid print density with the minimum color difference between the $CIEL^*a^*b^*$ color specification values in GRACoL standards and the measured color specification values in prints, was studied.

  • This study examined the wastewater at a livestock farm, and found that the dairy wastewater from the milking parlor had a lower concentration than the piggery wastewater, and that it was produced at a rate under 1.3 ㎥/day in a single farmhouse. The amount of dairy wastewater was determined based on the performance of the milking machine, the maintenance method of the milking parlor, and the amount of milk production allocated for each farmhouse, not by the area. The results confirmed that both dairy wastewater treatment processes, specifically those using Hanged Bio-Compactor (HBC) and Sequencing Batch Reactor (SBR), can fully satisfy the water quality standards of discharge. The dairy wastewater has a lower amount and concentration than piggery wastewater, meaning it is less valuable as liquid fertilizer, but it can be easily degraded using the conventional activated sludge process in a public sewage treatment plant. Therefore, discharging the dairy wastewater after individual treatment was expected to be a more reasonable method than consigning it to the centralized wastewater treatment plant. The effluent after the SBR process showed a lower degree of color than the HBC effluent, which was attributed to biological adsorption. In the case of the milking parlor in the livestock farm, the concentrations of the effluents obtained after HBC and SBR treatments both satisfied water quality standards for the discharge of public livestock wastewater treatment plants at 99% confidence intervals, and the concentrations of total nitrogen and phosphorous in untreated wastewater were even lower than the water quality standards of discharge. Therefore, we need to discuss strengthening the water quality standards to reduce environmental pollution.

  • This paper enables stakeholders involved in textile industry to gain an overview of standards used for care labelling and help establish a common standard that could be used as a universal standard. This study provides a comprehensive and detailed analytical study of care labelling standards adopted by common countries in the textile market. It was found that the development of a universal system for care labeling could enhance the trade of textile articles and assist consumers in caring for textile articles. Universal care label systems could be characterized by two main features of inclusiveness and comprehensiveness. The range of instructions and symbols presented were found different among standards. Insignificant differences in symbols' shapes were found between standards for bleaching, ironing and professional cleaning. The washing process had the widest variety of instructions; in addition, options were provided by stated standards. Different meanings were found for similar shapes in some tumble drying symbols. The study findings show the importance of enhancing text based standards or the development of an understandable format across as many cultures as possible. The unification of symbols and meanings may be needed to provide global consumers consistent guidance. The efficiency of a detailed standard that provides and covers a wide range of instructions is an important aspect. The visibility and practicality of offering variable options/symbols in one standard is an important aspect for developing a universal care label system.
