Currently the problem of air pollution caused by the motor vehicle emission is one of the most serious problems to be solved. Thus we needed the vehicle emissions audit procedure and technical innovation constraining the motor vehicle emission. The Korean Environmental Protection Agency currently audits automobiles for emissions compliance at assembly plants with multiple attribute multiple staged sampling plans. In order to establish the more reasonable audit procedure, the multiple staged sampling plan designed in this paper has been applied to the domestic vehicles by analyzing the statistic characteristics of the emission distribution. This paper summarizes the auditing procedure and develops methods for determining its statistical characteristics. Specifically, we consider how to evaluate a multiple staged sampling plan, give a procedure that efficiently estimates attribute-type probabilities from multivariate variables-type data, and quantify the effect of tightening the acceptable quality level of the sampling plan. As a result it can be proved that this audit procedure is the reasonable plan minimizing the AQL (Acceptable Quality Level) and is to be used effectively for the auditing procedure constraining the injurious gasses of the motor vehicles.

This study analyzes how companies of prospector type with inherent risks from new products and R&D costs affect audit hours, and further analyzes how they affect rank-specific audit hours. Samples were empirically analyzed using samples from 2018 to 2019 for KOSPI-listed and KOSDAQ-listed companies. As a result of the analysis, first, it was found that auditors were aware of the inherent risks of companies of prospector type and were striving to improve audit quality. Second, it was found that the corresponding degree of risk differs depending on the position and role in the audit team, so higher efforts were made in core positions with high risk levels. The results of this study are meaningful in verifying how the type of Business Strategies affects the audit efforts and resource input of auditors who are external parties, not internal factors such as financial reporting quality or tax avoidance. It also has important implications that a company's Business Strategies can be an significant factor to consider in preparing policies and systems for improving audit quality.

PCAOB conducts the direct supervision for the PCAOB registered accounting firm. Therefore, if an accounting firm is registered with the PCAOB, it will thoroughly manage for their quality management systems. The registered auditor can be expected to have better quality of the audit. This study carried out the analysis using the audit fee which proxies for audit quality. The results of analysis are as follows. After controlling for foreign accounting firms affiliated status, company size, risky assets, leverage, ROA, and market-related variables, PCAOB is a significant explanatory variable for the audit fees. The results of this study support the hypothesis that PCAOB-registered auditors will provide a good audit quality.

In this study, we investigate the effects of disclosure and high-quality audit on donations to charitable organizations in Korea. We find that the mandatory disclosure of financial information and high-quality audit is significantly and positively related to donations to charitable organizations. We also find that charitable organizations audited by Big 4 audit firms have greater likelihood to receive more donations, compared to those audited by non-Big 4 audit firms. Furthermore, we find that those positive associations are more pronounced for smaller charitable organizations. Collectively, those results imply that, as in the profit-making sector, disclosure and high-quality audit play a critical role in enhancing accountability and transparency of financial reporting and revenue for charitable organizations.

The information system audit service has been recognized for its effectiveness in improving the management efficiency of informatization projects in the public sector and improving the quality of information systems. However, according to several recent studies, it is not very helpful in securing quality by indicating formal audit performance and incorrect functions or errors in a short audit period. So, if the effectiveness of audit is proved to ensure the quality of the information system from the perspective of the software life cycle and to successfully operate and maintain it, the use of audit for the successful construction of the information system will be an essential factor. Therefore, this study investigated whether the current audit service users are satisfied with the current information system audit and what they expect. If it is different from what was expected, the difference between expectations and performance was analyzed to improve user satisfaction, and a survey was conducted through interviews with experts in the information system field. Based on the empirical results through the questionnaire, in order to reduce the difference in expectations from the user's point of view in the information system audit service, a plan to improve the audit system suitable for the new audit environment was proposed.

The study examines the effects that non-audit service and firm's ownership structure might have on the value relevance directly or indirectly. This investigation is based on prior research which suggests that the audit firms' non-audit services is likely to adversely affect investors' perceptions of the credibility of financial reporting and that corporate governance are likely to mitigate the adverse this kind of non-audit services effects. The sample consists of non-banking firms listed on the Korea Exchange that reported annual financial statements over the period from 2004 to 2008. In the setting, stock returns as proxy for capital market response, auditor quality(measured as the discretionary accruals) is endogenously determined. This study employs a structural equation model to take into account the endogenous variables under study. The analysis influences through the path analysis that ownership structure suppress the market response through audit quality and also the non-audit service have influence on the market response through audit quality. The results of this study contribute to the literature in the following ways. First, this provides direct evidence that there is a negative association between audit firms' client importance and the value relevance. Second, the findings that the negative association is attenuated for audit quality support the findings of prior studies which present that corporate governance provide higher credibility of financial reports.

Purpose - The main question in this study is whether there is any relationship between corporate governance variables and earnings quality. The size of the board and audit committee, the number of stockholding managers and non-executive directors, and management quality are considered as independent corporate governance variables in the hypotheses. Research design, data, and methodology - Earnings quality is used as the dependent variable. Input from the abovementioned variables are drawn from 94 listed companies in the Tehran Stock Exchange for the period between 2006 and 2010. Results - This study examines corporate governance aspects such as the size of the board of directors, the number of shares held by the board, the board's independence, and the percentage of non-executive directors. The results show that establishing an audit committee has a significant role in ensuring higher quality reported earnings. Conclusions - The regression statistics output reveals a meaningful relationship between earnings quality and the size of the board of directors, the number of non-executive directors, and the size of the audit committee. This result indicates that improving earnings quality requires that the size of the board of directors be taken into account.

Purpose: In order to improve the audit quality of a company, an in-depth analysis is required to categorize the audit report in the form of a text document containing the details of the external audit. This study introduces a systematic methodology to extract keywords for each group that determines the differences between groups such as 'audit plan' and 'interim audit' using audit reports collected in the form of text documents. Methods: The first step of the proposed methodology is to preprocess the document through text mining. In the second step, the documents are classified into groups using machine learning techniques and based on this, important vocabularies that have a dominant influence on the performance of classification are extracted. In the third step, the association rules for each group's documents are found. In the last step, the final keywords for each group representing the characteristics of each group are extracted by comparing the important vocabulary for classification with the important vocabulary representing the association rules of each group. Results: This study quantitatively calculates the importance value of the vocabulary used in the audit report based on machine learning rather than the qualitative research method such as the existing literature search, expert evaluation, and Delphi technique. From the case study of this study, it was found that the extracted keywords describe the characteristics of each group well. Conclusion: This study is meaningful in that it has laid the foundation for quantitatively conducting follow-up studies related to key vocabulary in each stage of auditing.
