The purpose of this study was to suggest a guideline for systematic and practical critical success factors of the External IT audit. For this purpose, an integrated conceptual model is developed considers that the service quality, and the IS(Information Systems) success with a contingency viewpoint. The model is tested using 254 data of IS projects which procured the external IT auditing service in public sector of Korea. The results of this study are as follows. First, service quality attributes of responsiveness, reliability, and tangibility have positive influence on IS implementation process quality. Second, the external IT audit quality obviously contributes to IS implementation success considering both IS implementation process quality and IS system quality. However it has positive influence on the process quality directly and the system quality indirectly.

This research examines the impact of audit quality on the extent to which firm-specific information is integrated with a firm's share price - which is determined inversely using stock price synchronicity. The study sample consists of non-financial companies listed on the Amman Stock Exchange i.e., the Jordanian Stock Market, from 2014-2018. After examining 810 firm-year observations from Jordanian industrial companies listed on the ASE, during the study period, we find that the companies using one of the BIG4 audit firms for auditing have less synchronous and more informative stock prices, suggesting high-quality audit improved governance and reduce information asymmetry between firms' insiders and investors which enhances the capitalization of firm's specific information into the stock price, thus less synchronous and more informative stock return. The findings remain consistent over 2 separate measurements of stock price synchronicity (Market and Industry model and Market Model) and show robustness for fixed effect tests. Our multivariate regression results are also robust after controlling for a number of features at the firm level with potential associations with stock price synchronicity. These include the firm size, leverage, return on assets (ROA), and market to book value (MBV).

In recent years, by utilizing the greatest strengths of process mining, the various research activities have been actively progressed to use auditing work of business organization. On the other hand, there is insufficient research on systematic and efficient analysis of massive data generated under big data environment using process mining, and proactive monitoring of risk management from audit side, which is one of important management activities of corporate organization. In this study, we intend to realize Hadoop-based internal audit integrated real-time monitoring system in order to detect the abnormal symptoms in prevent accidents in advance. Through the integrated real-time monitoring system for purchasing audit, we intend to realize strengthen the delivery management of purchasing materials ordered, reduce cost of purchase, manage competitive companies, prevent fraud, comply with regulations, and adhere to internal control accounting system. As a result, we can provide information that can be immediately executed due to enhanced purchase audit integrated real-time monitoring by analyzing data efficiently using process mining via Hadoop-based systems. From an integrated viewpoint, it is possible to manage the business status, by processing a large amount of work at a high speed faster than the continuous monitoring, the effectiveness of the quality improvement of the purchase audit and the innovation of the purchase process appears.

This research is aiming to specify the requirement of the investment such as initial cost, running cost earning rate to make effective investment considering the purpose of remodeling and economical value of store building enough to meet the initial purpose of remodeling. The review of earning rate for economical evaluation was performed by the on-site auditing on the structure and function of the building and applying the assessment simulation program, which is to find the possible business model to identify the requirement of building owner through case study. After the research, the following results are obtained. First, it is important that many aspects should be carefully analysis and the best method should be selected as characteristics of remodeling can tie defer each other in their implementations. Second, though the remodeling of exist buildings to promote the functions has been applied. no suitable assessment tool has bee developed for deriding the level of remodeling in the view of economical efficiency so far. Third, the economical benefit was evaluated by analysing annual earning rate which is applied by investment items and recovery period for the investment. More specific data base should be established to apply the suggested economic accession in business enough to forecast the future circumstances. More researches should be promoted on this area continuously as well as the integrated economic evaluation of remodeling on existing building.

This study examines the effects of entrepreneurial orientation and external oriented organizational culture on the firm perfornamance focusing on mediating effects of open innovation. The survey was conducted on Korean manufacturing firms with 100-5,000 employees among listed companies and external auditing companies. The validity of the research model and hypotheses was verified through analysis of structural equation model for 283 valid responses. Empirical results show that entrepreneurial orientation positively affects both open innovation and firm's performance. The external oriented organizational culture of firms appears to be positive effects on open innovation, but the effect between the external oriented organizational culture and firm's performance shows no statistical significance. Open innovation have positive effects on firm performance. In addition, a test for mediation effects of open innovation reveals that a full mediation exists between the external oriented organizational culture and firm's performance, while there is a partial mediation effect between entrepreneurial orientation and firm's performance. This study contribute to the literature by deepening understanding on the open innovation. We propose an integrated model for examining antecedent factors, open innovation and performance.
