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.

최보람,최다혜,허경회,이원진,허민석,최순철,배광학,이삼선 대한영상치의학회 2012 Imaging Science in Dentistry Vol.42 No.3

Purpose: The purpose of this study was to investigate the level of clinical image quality of panoramic radiographs and to analyze the parameters that influence the overall image quality. Materials and Methods: Korean dental clinics were asked to provide three randomly selected panoramic radiographs. An oral and maxillofacial radiology specialist evaluated those images using our self-developed Clinical Image Quality Evaluation Chart. Three evaluators classified the overall image quality of the panoramic radiographs and evaluated the causes of imaging errors. Results: A total of 297 panoramic radiographs were collected from 99 dental hospitals and clinics. The mean of the scores according to the Clinical Image Quality Evaluation Chart was 79.9. In the classification of the overall image quality, 17 images were deemed ‘optimal for obtaining diagnostic information,’ 153 were ‘adequate for diagnosis,’ 107 were ‘poor but diagnosable,’ and nine were ‘unrecognizable and too poor for diagnosis’. The results of the analysis of the causes of the errors in all the images are as follows: 139 errors in the positioning, 135 in the processing, 50 from the radiographic unit, and 13 due to anatomic abnormality. Conclusion: Panoramic radiographs taken at local dental clinics generally have a normal or higher-level image quality. Principal factors affecting image quality were positioning of the patient and image density, sharpness, and contrast. Therefore, when images are taken, the patient position should be adjusted with great care. Also, standardizing objective criteria of image density, sharpness, and contrast is required to evaluate image quality effectively.

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.

Purpose: This paper proposes a quality strategy based on the evolution of technology in the age of the 4th Industrial Revolution. Methods: We examine the theory of past quality activities and the changes in quality paradigm, and analyze key words for the technologies and key issues of the 4th Industrial Revolution. Based on existing quality management, we find a quality strategy that should be pursued during the 4th Industrial Revolution. Results: Quality has been recognized as an essential component of corporate competitiveness. The paradigm of quality has also changed with the pass of time and industry development. From this viewpoint, the following eight quality strategies are proposed for the development of the technology of the 4th Industrial Revolution period, such as Market-to-customer fusion quality, symbiotic quality, big data quality, technical accuracy and zero-defect quality, facility predictability quality, software quality, process flexibility quality, and information protection stability and security quality. Conclusion: Quality for customer satisfaction is still important nowadays. However, in the 4th Industrial Revolution era, where various business models and methods of manufacturing are expected, the big data utilization, software quality, and the reliability and security of information protection to support it are important.

기획논문: 정부의 질과 시민사회: 비판적 검토와 지표 개발을 위한 시론

김선혁 ( Sun Hyuk Kim ) 고려대학교 정부학연구소 2011 정부학연구 Vol.17 No.3

본 논문은 최근 서구 학계에서 큰 관심의 대상이 되고 있고 국내 학계에도 막 소개되기 시작한 ``정부의 질(Quality of Government)`` 논의를 비판적으로 검토하고 정부의 질 연구가 각국 행정과 정책의 비교 분석틀로서 보다 유용하게 쓰이기 위해서는 시민사회와 관련된 지표들이 적극적으로 개발, 포함되어야 한다고 주장한다. 우선 정부의 질 논의의 지식사적 맥락을 살펴보기 위해 삶의 질, 사회의 질, 시민사회의 질, 거버넌스의 질(굿 거버넌스), 민주주의의 질 등 다양한 Quality학의 등장과 발전 과정을 살펴본다. 이어 현 단계 정부의 질 논의의 핵심내용을 정리한 후 그것이 선행 굿 거버넌스(Good Governance) 논의와 민주주의의 질(Quality of Democracy) 논의와의 차별성을 강조하려는 의욕이 지나쳐 시민사회와 관련된 요소들을 망실하는 愚를 범하였다고 분석한다. 이에 본 논문은 정부의 질 논의에 시민사회가 왜 포함되어야 하는가, 그리고 구체적으로 어떻게 포함될 수 있는가를 행정학의 다양한 주제 영역에서 탐색적으로 살펴본다. 결론적으로 현행 ``정부의 질`` 논의가 보다 일반적인 비교 분석틀로 발전하기 위해서는 그것이 ``시민사회 친화적인`` 논의로 전환되어 이론적으로는 굿 거버넌스론과 민주주의의 질 논의를 심화·확장시키고 정책적으로는 전 세계적으로 민주주의를 진작시키는 역할을 해야 한다는 점을 강조하면서 논의를 맺는다. This paper critically reviews the current literature on the "Quality of Government(QoG)" and proposes that, for the QoG literature to be more broadly used as a useful comparative framework, it is imperative to take civil society into serious consideration. The paper first probes the intellectual-historical background of the emergence and development of the QoG discussion, ``reflecting on various quality-related literatures such as the ``Quality of Life,`` ``Quality of Society,`` ``Quality of Civil Society,`` ``Quality of Governance (Good Governance),`` and ``Quality of Democracy.`` Next, the paper observes that the QoG literature, out of its excessive zeal to differentiate itself from the preceding Good Governance and Quality of Democracy literatures, has erred in neglecting civil society-related variables. This paper therefore demonstrates why it is crucial to associate civil society with the quality of government and how we can effectively incorporate civil society-related variables into the discussion on the quality of government. In conclusion, the paper emphasizes that changing the current QoG into a more civil society-friendly QoG will deepen and expand the Good Governance and the Quality of Democracy literatures and will eventually contribute to the promotion of democracy worldwide.

The Quality Costs Assessment in the Aspect of Value Added Chain

( Asta Daunoriene ),( Egle Katiliute ) 한국품질경영학회 2015 한국품질경영학회 학술대회 Vol.2015 No.2

Purpose - The dynamism and chaos of organizational environment has been stated by the analytics of organizational performance. In order to survive in such rapidly changing environment, organizations have to adapt and be able to anticipate changes, to forecast probable activity scenarios that could provide maximum expected benefit. Acknowledging this, many innovative organizations have been involved in management and improvement activities consider the value chain which is based on interaction between the businesses processes functions and management activities. The managerial benefits of value chain analysis has been recognized many scientists still acknowledge that value chain management is inseparable from the investment that is directed towards quality and reduction of the loss that is as well as associated with quality. According to Campanella (1999) and Wood (2013) the assessment of the investment that is directed towards quality and the loss that is associated with quality can be made through application of the analysis of quality cost. However, it should be noted that quality costs aren□t analysed with the value chain activities in order to increase added value. This paper aim focus on the quality costs influence direction and intensity on the added value in the aspect of value chain. Methodology/approach - The article is based on a nomothetic point of view that includes three modules: conceptual, hypothetical - deductive and inductive methods. To formulate theoretical aspects of quality costs evaluation, comparative and chronological analysis of scientific literature is used. Empirical results of the research are obtained by applying method of expert evaluation. Findings - During expert evaluation procedure is identified and selected significant quality costs elements. It is a useful tool to identify quality costs thought value chain processes. Created model of quality costs assessment in the aspect of value added chain is based on identification and classification of quality costs elements and allows to measure and to evaluate influence of quality costs, its direction and intensity on added value. Research limitations/implications - The formulated model of quality costs assessment in the aspect of value added chain is assigned to the models that “are oriented towards the situation”, i.e. diverted towards organizational analyses. Originality/value - The paper complementing the gap between theoretical and practical framework of determining influence of quality costs on added value and proving importance of the assessment of quality costs elements in the aspect of added value chain.
