박동준(Dong Joon Park) 한국산업경영시스템학회 2016 한국산업경영시스템학회지 Vol.39 No.1

Quality has been a key issue to manufacturers. Many distinguished scholars have defined quality with profound insight. Korean firms struggle to make better products to fulfil requirements and satisfy customers. Korean industries have implemented quality management from Japan in early 70s. Statistical quality control, QCC (Quality Control Circle), and total quality management have also been introduced in succession. Chief executive officers, managers, and field employees have been aware of the importance of quality since then. This quality movement force workers to improve quality. They have to maintain the quality of products and compete with foreign products. Korean industries were able to compete with foreign industries in price. However, Korean firms now have to compete in quality as well as price. ISO (International Organization for Standardization) was established and industries around world have started to implement standardized systems depending on their need. ISO 9000 has continuously been revised and firms around world started to register a ISO 9000 certificate. Today’s quality competitiveness gets more deeply involved. KSA (Korean Standard Association) have launched QCAS (Quality Competitiveness Assessment System) since 1997. Up until now recent status of QCAS have been reported but the characteristics of QCAS results have not been analyzed. In this article we examine the QCAS results of 41 firms in 2014. QCAS consisted of 13 subsections : strategy and management system, organization culture and development of human resource, information management, quality system, customer satisfaction, management achievement, TPM, logistics, product development and technology, PL, QCC, SQC/SPC, and reliability. We performed one way ANOVA to discover the difference among the levels of firm size, business type, and quality hall of fame using the total scores of 13 subsections resulted from QCAS. We also analyzed the scores of 13 individual subsections of QCAS to see if there is any differences based on firm size and business type. We interpret the results and implication of analysis and finally draw a conclusion.

( Falk Behmer ),( Roland Jochem ),( Henry Hanke ) 한국품질경영학회 2015 한국품질경영학회 학술대회 Vol.2015 No.2

Purpose - Driven by globalization, manufacturing enterprises have faced strong international competition over the past decades. In order to successfully compete in a high cost environment, enterprises must be highly adaptable to increased market dynamics and customer expectations, as well as shortened product lifecycles. Environmental changes have an immediate effect on organizational structures, as their complexity grows with market complexity, making it more and more difficult to master the three basic organizational challenges: granting stability, efficiency, and flexibility to put strategy into practice. This results in an organizational problem for quality management, namely that in order to assure high quality products as a main competitive factor, quality management organization must be planned and implemented according to dynamic surrounding conditions. Thus, planning and implementing quality-related processes and organizational structures has developed into an essential managerial discipline. This p per presents challenges, motives and success factors of planning and reorganizing quality management organizations. It also gives an overview about involved stakeholder groups and tools to create a basis for improved planning practice. Methodology/Approach - This paper is based on an empirical study focused on quality management organization (QMO) -related planning activities and reorganization processes of manufacturing industry headquarters in Germany, Austria and Switzerland. The authors conducted an online survey on this topic between November 20th and December 3rd, 2014. Personalized invitations were sent to respondents via email. Overall, 411 answers were collected. The survey primarily included questions with alternative or selectable answers and, where suitable, a five-stage Likert scale was additionally applied. The gathered data were analyzed with descriptive statistical methods and hypothesis testing. Findings - A long-term oriented, pro-active planning approach towards quality structures was found to have a significant impact on appropriate QMO capabilities. However, a gap was discovered between the valuated importance of long-term oriented planning and current corporate practice. Divisional QMO structures were found superior over functional or matrix structures in terms of capability, planning, and reorganization. Enterprises that aimed to improve product quality, as well as process quality, and to reduce interface were more successful in their QM reorganizations than those that aimed for cost cutting. The use of certain planning tools also increased success in this matter. Novel technologies and products as well as corporate growth were found to be the biggest challenges. Originality - Existing studies focus on general organizational structures. Due to the comparably high number of interfaces and strong product relation of QMO, planning and implementation activities pose a distinct challenge that requires specialized attention. Digitalization will increase the future number of reorganizations in manufacturing. As quality is one of the most important factors for contemporary entrepreneurial success, quality managers must be scientifically supported in order to close the gap between the importance of long-term planning and current practice. This paper contributes with an in-depth analysis.

Usman, Muhammad Arslan,Usman, Muhammad Rehan,Shin, Soo Young Elsevier 2017 Computers in biology and medicine Vol.91 No.-

<P><B>Abstract</B></P> <P>Maintaining the quality of medical images and videos is an essential part of the e-services provided by the healthcare sector. The convergence of modern communication systems and the healthcare industry necessitates the provision of better quality of service and experience by the service provider. Recent inclusion and standardization of the high efficiency video coder (HEVC) has made it possible for medical data to be compressed and transmitted over wireless networks with minimal compromise of the quality. Quality evaluation and assessment of these medical videos transmitted over wireless networks is another important research area that requires further exploration and attention. In this paper, we have conducted an in-depth study of video quality assessment for compressed wireless capsule endoscopy (WCE) videos. Our study includes the performance evaluation of several state-of-the-art objective video quality metrics in terms of determining the quality of compressed WCE videos. Subjective video quality experiments were conducted with the assistance of experts and non-experts in order to predict the diagnostic and visual quality of these medical videos, respectively. The evaluation of the metrics is based on three major performance metrics that include, correlation between the subjective and objective scores, relative statistical performance and computation time. Results show that the metrics information fidelity criterion (IFC), visual information fidelity-(VIF) and especially pixel based VIF stand out as best performing metrics. Furthermore, our paper reports the performance of HEVC compression on medical videos and according to the results, it performs optimally in preserving the diagnostic and visual quality of WCE videos at Quantization Parameter (QP) values of up to 35 and 37 respectively.</P> <P><B>Highlights</B></P> <P> <UL> <LI> This study presents video quality assessment for HEVC compressed wireless capsule endoscopy (WCE) videos. </LI> <LI> Based on our findings, high diagnostic quality can be maintained in WCE videos if compression level QP is kept ≤ 35. </LI> <LI> On the other hand, high visual quality can be maintained for larger QP values (QP ≤ 37), hence allowing more compression. </LI> <LI> Further in our study, state-of-the-art objective metrics are compared for estimating the quality of WCE videos. </LI> <LI> Pixel based Visual information fidelity (VIFP) metric outperforms other metrics in measuring the quality of WCE videos. </LI> </UL> </P>

석민준,황창수,이수호,이준식,송동훈,박상표 한국수로학회 2023 한국수로학회지 Vol.12 No.2

립해양조사원(KHOA, Korea Hydrographic and Oceanographic Agency)은 국가해양관측망의 안정적인 운영과 해양관측자료의 품질 향상을 위하여 관측시설물 유지관리와 해양관측자료의 품질처리(실시간 및 비실시간)를 수행하고 있다. 실시간 품질처리는 다양한 물리적 알고리즘 및 기준을 이용하여 자동 품질처리를 수행하는 것으로, 실시간 품질처리가 완료된 관측자료는 ‘국립해양조사원 홈페이지 누리집’을 통해 제공 중이다. 비실시간 품질처리는 매월 초순에 전월의 관측자료를 대상으로 품질관리 담당자가 수동 품질처리를 수행하는 것이며, 비실시간 품질처리가 완료된 자료는 가공 및 분석을 통해 통계 자료, 1시간 조위 등을 산출하여 해당 정보들을 간행물에서 제공하고 있다. 본 연구는 국내 해양관측자료의 품질처리 방법 개선을 위하여 기존 실시간, 비실시간 품질처리 기법 외 적용이 가능한 준실시간 품질처리 기법을 조사하고, 해당 기법을 해수위 관측자료에 적용 및 실험하여 활용 가능성을 검토하였다. 해양관측자료 준실시간 품질처리 기법의 조사 결과, 다양한 해양과 관련된 국제적인 유관기관(IOC, GLOSS 등)에서는 해수위(조위) 관측자료의 품질개선을 위해 SELENE(SEa LEvel NEar-real time quality control processing) 알고리즘의 적용을 적극 권장하고 있다. 이에 국립해양조사원의 조위관측소에서 수집한 조위 자료에 대해 품질처리 최적화 실험을 통해 적합한 매개변수를 산출하였으며, 해당 기법을 적용하여 품질처리 정확도를 분석하였다. 분석 결과, 특이상황을 제외한 조위 관측자료의 준실시간 품질처리 정확도는 평균 90% 이상으로 매우 양호하게 나타났다. 따라서 실시간 및 비실시간 품질검사 외 해당 준실시간 품질처리 기법을 품질검사 현업에 도입·적용한다면, 조위 관측자료의 품질개선과 더불어 신속한 품질처리 자료 생산으로 해양정보 서비스 활용도 향상에 큰 도움이 될 것으로 생각된다. The main responsibility of Korea Hydrographic and Oceanographic Agency (KHOA) is to operate the Korea Ocean Observing and Forecasting System(KOOFS) and enhance the quality of observed oceanographic data. To achieve this, KHOA maintains facilities and quality control of observed oceanographic data in real-time and non-real time. real-time quality control means automatic quality control using various physical algorithms. The data for which real-time quality control has been completed is provided on the the KHOA Homepage. Non-real time quality control means manual processing by oceanographic experts.statistical data, hourly tidal levels, and other information, which is made available through publications. The purpose of study is to enhance the quality processing performance of marine observation data by applying near-real time quality control techniques in addition to the existing quality control methods. First, a survey was conducted on the various quality processing techniques used by various international organizations. And then, among the surveyed techniques, suitable methods were applied to sea level data for experimentation. According to the results of the investigation into near-real time quality management technology, various institutions strongly recommend the use of the SELENE(SEa LEvel NEar-real time quality control processing) algorithm for improving the quality of sea level data. To determine suitable parameters, optimization experiments were conducted using sea level data observed at KHOA's tidal observation station. This algorithm was then utilized to measure the accuracy of quality control data. As a result, the accuracy of near-real time quality-managed sea level data except in special situation was found to be above 90% on average. If it would use the near-real time quality management technique and utilizing it in conjunction with real-time and non-real time quality management would not only enhance the quality of sea level observation data but also enable swift quality management. Therefore, it is expected to significantly contribute to the improvement of marine information services.

A Study on the Evaluation of Multi-dimensional ASP Service Quality and Its Effects on User Satisfaction and Perceived Firm Performance

김성홍(Sung-Hong Kim),김진한(Jin-Han Kim),김길선(Kilsun Kim) 한국경영과학회 2008 韓國經營科學會誌 Vol.33 No.2

Quality has long been considered as an important factor in creating competitive advantage, and researches on quality have not been limited to off-line products but actively extended to e-services and information goods. However, given the nature of multi-dimensional aspect of quality, the systematic study on the quality of online service is still in its early stage. Especially, studies on the quality of ASP services have been rare in academic and professional journals despite the growth of ASP industry in its size and the rapid expansion in the range of application. In this paper, we clarified the multi-dimensional quality aspects of the ASP service using a Garvin’s framework (1984) which encompasses the service aspects of products, and developed a measurement model for ASP service quality. Then we empirically tested the effects of ASP service quality on user satisfaction and perceived firm performance using the data from 240 Korean small firms with less than 50 employees that had experienced the ASP service. Our results show that there are positive relationships among ASP service quality and personal performance, user satisfaction and perceived firm performance, and that product and service-related aspects of ASP service exert differential effects on performance measures so that the product-related aspects of the ASP service such as performance, features, reliability and conformance are considered to be more important in evaluating benefits from ASP services. Contrary to the approaches in literature where only the quality of online services is evaluated, our results emphasize the importance of differentiating product and service-related aspects of ASP service and provide a basis for more comprehensive evaluation of ASP service quality.

발생액의 질의 회계정보 유용성

손성규,고재민,백혜원 한국회계정보학회 2009 회계정보연구 Vol.27 No.2

The objective of this study is to investigate whether accruals quality, an alternative measure of accounting information quality, has an information content in the capital market. Traditionally discretionary accruals are used as a proxy of accounting information quality. However, discretionary accruals might imply earnings management or deliver managers' private information. Thus the discretionary accruals could cause a measurement error problem. Dechow and Dichev(2002) argued that discretionary accruals which are realized into future cash flows cannot be a outcome of earnings management but a signal of future performance. In this perspective, accruals quality measured with cash flows of previous, current, and next period is considered to overcome the measurement error of discretionary accruals. The superior accounting information would accompany bigger stock price reaction by its predictability and precision, and smaller trading volume reaction by mitigating the heterogeneity among investors. In order to test an information content, we examine if stock price reaction is bigger and trading volume reaction is smaller as accruals quality increases. In addition, we compare an information content of accruals quality with that of discretionary accruals. This will enable us to recognize which measure is more effective in judging quality of accounting information in the capital market. Our empirical results are as follows. First, the higher the accruals quality, the bigger the stock price reaction with the same unexpected earnings. Second, the higher the accruals quality, the smaller the trading volume reaction with the same stock price change. Third, stock price reacts more and trading volume reacts less in superior accounting information assessed by accruals quality than discretionary accruals. Our findings show that accruals quality is a significant measure of accounting information quality. Furthermore, it could be a better proxy of accounting information quality than discretionary accruals in the capital market. Therefore, we suggest that researchers should use accruals quality in valuing quality of accounting information. 본 연구의 목적은 발생액의 질(accruals quality)이 회계정보의 질을 평가하는 측정치(proxy)로 적정한지를 검증하는 것이다. 즉 발생액의 질이 자본시장에서 어떻게 평가 받는지를 분석함으로써, 정보유용성이 있는지를 살펴보는 것이다. 전통적인 측정치인 재량적발생액이 사적 정보의 전달과 이익조정의 수단이라는 양면성을 가지고 있기 때문에, 재량적발생액의 크기만으로 회계정보의 품질을 평가하는 것은 논란의 여지가 있다. Dechow and Dichev(2002)는 재량적발생액이라도 실제로 현금으로 실현되는지 여부에 따라 회계정보의 질을 평가함으로써, 재량적발생액이 갖는 측정 오차를 극복하고자 하였다. 양질의 회계정보는 이익 공시 시점에서 높은 예측 가능성(predictability)과 정확성(precision)으로 주가 반응은 클 것이며, 회계정보 해석의 이질성(heterogeneity)을 완화시켜 거래량 반응은 작을 것이다. 따라서 발생액의 질에 따라 회계이익이 주가수익률에 미치는 영향과 주가 변동이 주식 거래량에 미치는 영향이 어떻게 달라지는지를 살펴보았다. 또한 회계정보의 질에 대한 전통적인 측정치인 재량적발생액과 발생액의 질에 대해 주가 반응과 거래량 반응을 비교함으로써, 회계정보의 질을 평가하는 데 있어 어떤 측정치가 시장에서 더 유효한지를 검증하였다. 실증 분석 결과는 다음과 같다. 첫째, 같은 비기대이익 수준이라 하더라도 발생액의 질이 높은 기업은 주가 반응이 더 크게 나타났다. 둘째, 주가 변동의 정도가 같더라도 발생액의 질이 높은 기업은 거래량 반응이 더 작다는 사실을 확인하였다. 셋째, 재량적발생액보다 발생액의 질로 평가한 양질의 회계정보에서 주가 반응은 더 크고 거래량 반응은 더 작다는 사실을 관찰하였다. 이는 발생액의 질은 자본시장에서 회계정보의 질을 평가하는 유효한 측정치로 인정 받고 있으며, 재량적발생액보다 더 의미 있는 측정치로 평가 받고 있음을 의미한다. 따라서 향후 자본시장 연구에서 회계정보의 질을 평가할 때는 재량적발생액 뿐 아니라, 발생액의 질을 적극적으로 도입하는 것이 필요하다고 제안한다.
