  • 전력품질에 대한 관심과 요구가 증가되고 있는 최근의 상황하에서 기존의 전력품질 관리방 법의 개선과 새롭게 대두되는 전력품질 사항에 대한 정확한 정의와 대책이 필요하게 되었 다. 국내에서는 아직 대비가 미비한 실정이며 외국의 경우에는 장비의 도입비용이 고가이며 고정형이 대부분인 문제가 있다. 본 논문에서는 새롭게 대두되는 미소 외란에 의한 전력품 질 사항에 대해 명확하게 판단하고 검출할 수 있는 알고리즘을 제시하였다. 개발된 측정장 치는 이동형으로 만들어졌으며 제작소요비용이 몇십 만원대로 그 기능이나 성능에 비해 저 렴하다. 그리고 500$\mu\textrm{s}$의 샘플링 시간에 의해 만들어진 입력 데이터로 실험을 하고 결과를 분석하여 장치의 효용성을 입증하였다.

  • 품질 관리의 목표는 최종제품의 품질 보증에 있다. 이러한 목표를 달성하기 위해서는 품질 특성이 명확해야 하며, 동시에 품질 특성치에 영향을 주는 공정의 여러 변동 요인을 분명히 해야 한다. 실험계획법(Design of Experiments)은 특성에 영향을 미치는 여러 인자를 선정하며, 또한 이들의 관계를 알아보기 위한 실험을 실시하여 제품의 최적 제조조건을 경제적으로 찾아내는 기법이다. 본 연구에서는 실험계획법을 사용하여 유량을 최적화하는 요인을 선정, 얻어진 데이터를 통계적 방법으로 분석하여 최적의 조건을 나타내었다.

  • The intensification and acceleration of severe competition among companies due to the advancement of the service industry have raised the quality level of services required by consumers, and these circumstances also have a significant impact on the public fields' service provision environment, which has to take into account the rapidly changing technologies along with the special situation of COVID-19. Thus, this study examines the applicability of the educational material based on the framework for public service quality management in accordance with 『ISO18091:2019』 developed by MOIS(the ministry of interior and safety), through a survey after training workers in public institutions. This study also provides some implications and guidelines that should be considered to increase the level of public service quality from the following three perspectives: i) data utilization and verification, ii) broadness of public services, and iii) the size and capability of service provider according to the results of field studies conducted with public sector employees who participated in actual improvement activities.

  • In this study, the accuracy duplication and register rate of the vaccination registration data in National Immunization Registry Information System were evaluated and analyzed. Through which undocumented vaccination status data, duplicate data, missing data, errors data into the vaccination registration data were analyzed. In addition, the quality control for the vaccination registration database quality improvement, were proposed for standard error checking. In this paper, we propose an efficient validation of a quality management system of the database.

  • In this paper, we propose a mobile remicon quality management system to enable inspection and correspondence with a smart phone in the field check of remicon. We also proposed a real-time slump data processing part to digitize field inspection and XML formats for data exchange with the server. We used the smart phone to transmit real-time image about field inspection of remicon and judged the error at the same time. By doing this, we shared the situation of the remicon products in the field and the head office. Based on the actual results, the development technology is used to determine whether the product is abnormal or not, and to provide appropriate information to the company and the site. Based on the analysis of raw material quality data, it is possible to present real time optimal blending ratio according to raw material import with raw material management data, which is the biggest problem of the ready mixed concrete industry.

  • 데이터세트 기록은 단순한 이관모듈의 작성이나 API를 제공하는 것만으로는 효과적이고 효율적으로 이관을 수행하기 어렵다. 데이터세트의 기록은 기록 건의 범위가 명확하지 않으며, 이관되는 과정에서 데이터의 보정과 품질개선이 필요하며, 메타데이터의 적극적인 수집보완이 요구되는 등 규격화된 전자문서 중심의 기록과는 이관 과정의 특성이 다르기 때문이다. 따라서 데이터세트 기록의 이관 시에는 세부적인 이관 절차를 따라 이관대상 데이터의 상태를 확인하고 필요한 조치를 취해나갈 수 있도록 지원해주는 이관도구가 필수적이다. 이관의 이관 작업과 달리 이관 작업을 지원하는 도구가 필수적이다. 이 논문에서는 행정정보시스템에서 데이터세트 기록을 추출하여 아카이브 시스템으로 이관하는 과정을 지원하는 도구가 갖춰야 할에 기능요건을 제시하고자 한다.

  • Many dairy producers periodically receive information about their bulk tank milk with reference to bulk tank somatic cell counts, standard plate counts, and preliminary incubation counts. This information, when collected over a period of time, in combination with bulk tank mastitis culture reports can become a significant knowledge base. Several guidelines have been proposed to interpret farm bulk tank milk bacterial counts. However many of the suggested interpretive criteria lack validation, and provide little insight to the interrelationship between different groups of bacteria found in bulk tank milk. Also the linguistic terms describing bulk tank milk quality or herd management status are rather vague or fuzzy such as excellent, good or unsatisfactory. The objective of this paper was to develop a set of fuzzy descriptors to evaluate bulk tank milk quality and herd's milking practice based on bulk tank milk microbiology test results. Thus, fuzzy logic based reasoning methodologies were developed based on fuzzy inference engine. Input parameters were bulk tank somatic cell counts, standard plate counts, preliminary incubation counts, laboratory pasteurization counts, non agalactiae-Streptococci and Streptococci like organisms, and Staphylococcus aureus. Based on the input data, bulk tank milk quality was classified as excellent, good, milk cooling problem, cleaning problem, environmental mastitis, or mixed with mastitis and cleaning problems. The results from fuzzy reasoning would provide a reference regarding a good management practice for milk producers, dairy health consultants, and veterinarians.

  • The frequent occurrence of structural failures at building construction sites in Korea has underscored the critical role of rigorous oversight in the inspection and management of construction projects. As mandated by prevailing regulations and standards, onsite supervision by designated supervisors encompasses thorough documentation of construction quality, material standards, and the history of any reconstructions, among other factors. These reports, predominantly consisting of unstructured data, constitute approximately 80% of the data amassed at construction sites and serve as a comprehensive repository of quality-related information. This research introduces the SL-QPA model, which employs text mining techniques to preprocess supervision reports and establish a sentiment dictionary, thereby enabling the quantification of quality performance. The study's findings, demonstrating a statistically significant Pearson correlation between the quality performance scores derived from the SL-QPA model and various legally defined indicators, were substantiated through a one-way analysis of variance of the correlation coefficients. The SL-QPA model, as developed in this study, offers a supplementary approach to evaluating the quality performance of building construction projects. It holds the promise of enhancing quality inspection and management practices by harnessing the wealth of unstructured data generated throughout the lifecycle of construction projects.

  • Sharing and reusing data has become essential. Data repositories are a key tool for sharing and reusing this data. The purpose of this study is to propose the service of EcoBank, which is being built and operated by the National Institute of Ecology. To achieve the research purpose, 10 out of 123 foreign data repositories in the field of ecology registered on re3data.org were selected, investigated, and analyzed. As a result of the analysis, three services were derived in common. The three services consist of first, research data policy, second, research data quality review, and research data management training and workshops. Here, in order to share EcoBank's global data, it is necessary to register with a data repository registry such as re3data.org, and it is proposed that certification be promoted to ensure the reliability and quality of the repository.

  • The purpose of this study was to propose applicability of spatial data and quality check criteria for estimating damage from storm and flood. Using the data from the National Disaster Management System and National Spatial Data Infrastructure, spatial database for estimation of storm and flood damage has been mapped to each type of damage. This was proposed as the quality check criteria for damage analysis. Through this study, it is possible to utilize the spatial database for estimating storm and flood damage. The reliability of analysis results are ensured through the quality check criteria.
