The purpose of this study is to make an empirical analysis of how voluntary disclosure level has an impact on auditor's audit fees and audit hours and additionally identify if the relationship between the twos depends on the accounting quality. As final sample for analysis, this study targeted the KOSPI listed firms from 2007 to 2013, and as for audit fees(audit hours), 4,572 (4,460) corporate/annual data were used. The results from the empirical analysis in this study are as follows. First, auditor's audit fees appeared higher in KOSPI listed firms compared to the non-KOSPI listed firms, and when targeting the KOSPI listed firms only, the results were the same. Second, auditor's audit hours increased significantly in the KOSPI listed firms compared to the non-KOSPI listed firms, and this result appeared consistently even when analyzing the KOSPI listed firms only. Third, when the accounting quality was not good in the KOSPI listed firms, auditor's audit fees got significantly lower, whereas when targeting the KOSPI listed firms only, no relevance was found. Fourth, when the accounting quality was bad in the KOSPI listed firms, auditor's audit hours were found to have been spent less, but when analyzing the KOSPI listed firms only, such a fact was not identified. This study is significant in that it examined the fact that auditor's audit risk depends on voluntary disclosure level in terms of audit fees and audit hours.

The public's interest in the information disclosure system is increasing daily in line with the democratic cause of a transparent government and demands of the people to build on their right to know. Meanwhile, as society develops, the importance of culture and art in the quality of life is also increasing. Under these circumstances, culture and arts institutions are seeking to contribute to the expansion of the people's participation by providing timely and useful information and programs with high interest. Accordingly, this study intends to propose customized information services by analyzing the user's needs for information on public institutions in culture and arts and reflecting on the information disclosure service. For this purpose, three public institutions of in the culture and arts will be selected as representative examples to collect and cross-analyze the list of disclosed information received by users over a year. Furthermore, the requirements for the automation and intelligence of information disclosure tasks were summarized, and specific improvement plans were proposed for customized information services.

Purpose - The purpose of this paper is to investigate the relationship between corporate social responsibility disclosure (CSRD) and investment-cash flow sensitivity, which is a surrogate for financing constraints. Research design, data, and methodology - Taking China's A-share listed companies between 2009 and 2016 as a sample, this paper empirically tests the relationship between CSRD and investment-cash flow sensitivity by Panel VAR model. By introducing the orthogonal impulse response function, this paper distinguishes the fundamental factors and financial ones that affect corporate investment behavior. Results - Findings indicate that: (1) investment-cash flow sensitivity of firms with low level of CSRD is significantly lower than that of firms with high level of CSRD; (2) the orthogonal impulse response of corporate investment to cash flow in firms with high level of CSRD is significantly different from zero, but it is not significant in firms with low level of CSRD; (3) for firms with low level of CSRD, 0.7% of corporate investment volatility can be explained by the change in cash flow, which is lower than that of firms with high level of CSRD (1.1%). Conclusions - Corporations disclosing more and higher quality CSRD are often those faced with financing constraints. Voluntary disclosure can help them alleviate information asymmetry and financing constraints.

Objectives: The purpose of this preliminary study was to identify the nurses' perception regarding disclosure of patient safety incidents (DPSI) and to evaluate the effectiveness of education for DPSI. Methods: DPSI education was conducted for nurses majoring in clinical nurse specialist at an university. Before and after the education, the nurses made a questionnaire to evaluate the perception of DPSI. The questionnaires were divided into four categories: first, overall perception of the DPSI; second, recognition evaluation of the DPSI using hypothetical case, third, opinion on legal and nonlegal measures for facilitating the DPSI; and fourth, socio-demographic factors. The Wilcoxon signed rank test was performed on the DPSI questionnaire response to compare the perceptions before and after the education. Results: A total of 10 nurses participated in the education. DPSI education showed the possibility of improving the overall perception, necessity, effect, obstacle, and promotion method of DPSI, although there were also several responses where there was no statistical significance. In particular, DPSI education led to statistically significance change in the perception of obstacles for DPSI. For example, the number of respondents who agreed to the item "DPSI will increase the incidence of medical lawsuits." was 7 before education but decreased to 3 after education (P-value: .025) Furthermore, nurses' perception of DPSI from this study was generally positive regardless of education. Conclusion:In the future, it will be necessary to carry out DPSI education and training and to evaluate its effectiveness for more nurses.

Purpose:We investigated physicians' responses to a series of clinical vignettes consisting of patient safety incidents, with and without disclosure of patient safety incidents (DPSI). Methods: An anonymous survey was conducted to investigate physicians' responses to the DPSI via online communities of physicians, and additional participants were recruited using a snowballing sampling method. We evaluated physicians' responses to the DPSI using eight hypothetical scenarios (HS) from the following perspectives: thoughts regarding medical errors, revisiting the physician, recommendation, lawsuit, criminal prosecution, trust score, and compensation amounts. We used the chi-square test to evaluate the overall differences in response rates among the scenarios. Statistical analyses were performed using the Student's t-test to compare the trust scores and compensation amounts. Results: A total of 910 physicians participated in this survey. An overall comparison of trust scores among HS showed that HS 1 (unclear medical errors, minor harm, and DPSI) had the highest trust score. In contrast, in the opposite scenario, HS 8 (clear medical errors, major harm, and DPSI not conducted) received the lowest scores. Cases with minor harm to patients (HS 1, 2, 5, and 6) showed lower compensation amounts than the others (HS 3, 4, 7, and 8). Physicians were more likely to think of situations with DPSI as not having medical errors (53.1% vs. 55.2%). In addition, the scenarios with DPSI were evaluated favorably in terms of intention to revisit, recommend, suit, and engage in criminal proceedings. Physicians showed higher trust scores (6.2 vs 5.4) and gave lower compensation amounts ($27.7 million vs $28.1 million), although there was no significant difference in terms of compensation amounts to the physician conducting DPSI. Conclusion: Our study showed overall positive perceptions regarding DPSI among Korean physicians.

Purpose - This study attempts to provide a new theoretical perspective on the quality signaling and its impact on a market under information asymmetry, focusing on how the accuracy and the cost of quality signaling affect sellers' and buyers' profit, suggesting appropriate designs of quality signaling methods which mitigates information asymmetry. Design/methodology/approach - In order to examine the effect of quality signaling on strategic interactions within the market, we establish an analytic model where market outcomes are determined by seller's quality claim and price, and buyers are risk-neutral. By investigating this analytic model through relevant game trees, we find the subgame perfect Nash equilibria of the market and predict related market outcomes based on sellers' quality signaling strategy. Findings - Our analytic model shows counterintuitive results that seller profit will be the lowest with inaccurate quality signaling and the highest with no quality signaling, mostly due to the certification cost. Consequently, sellers should proceed with caution if the quality signaling is less than accurate, as it may backfire. We believe that this is due to the fact that the inaccuracy of quality signaling causes some confusion and uncertainty in both sellers and buyers' decision to maximize profit, making it hard for sellers to predict buyers' behavior. Research implications or Originality - Although the sources and types of quality signaling errors have been investigated in the literature, there has not been satisfactory understanding regarding how inaccuracy of quality certification affects specific market outcomes. We expect that our theoretical model would provide important implications on how to utilize quality signaling to solve adverse selection issues in markets under information asymmetry.

Objectives: We performed a systematic review to assess and aggregate the available evidence on the frequency, expected effects, obstacles, and facilitators of disclosure of patient safety incidents (DPSI). Methods: We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for this systematic review and searched PubMed, Scopus, and the Cochrane Library for English articles published between 1990 and 2014. Two authors independently conducted the title screening and abstract review. Ninety-nine articles were selected for full-text reviews. One author extracted the data and another verified them. Results: There was considerable variation in the reported frequency of DPSI among medical professionals. The main expected effects of DPSI were decreased intention of the general public to file medical lawsuits and punish medical professionals, increased credibility of medical professionals, increased intention of patients to revisit and recommend physicians or hospitals, higher ratings of quality of care, and alleviation of feelings of guilt among medical professionals. The obstacles to DPSI were fear of medical lawsuits and punishment, fear of a damaged professional reputation among colleagues and patients, diminished patient trust, the complexity of the situation, and the absence of a patient safety culture. However, the factors facilitating DPSI included the creation of a safe environment for reporting patient safety incidents, as well as guidelines and education for DPSI. Conclusions: The reported frequency of the experience of the general public with DPSI was somewhat lower than the reported frequency of DPSI among medical professionals. Although we identified various expected effects of DPSI, more empirical evidence from real cases is required.

In existing mobile computing environments, users need to choose between their privacy and the services that they can receive from an application. However, existing mobile platforms do not allow users to perform such trade-offs in a fine-grained manner. In this study, we investigate whether users can effectively make utility-privacy trade-offs when they are provided with a multilevel privacy control method that allows them to recognize the different quality of service that they will receive from an application by limiting the disclosure of their private information in multiple levels. We designed a research model to observe users' utility-privacy trade-offs in accordance with the privacy control methods and other factors such as the trustworthiness of an application, quality level of private information, and users' privacy preferences. We conducted a user survey with 516 participants and found that, compared with the existing binary privacy controls, both the service utility and the privacy protection levels were significantly increased when the users used the multilevel privacy control method.
