  • Web applications are widely used by the development of the Internet, but there are no separate audit model for a web-based information systems. Information business has a wide variety of characteristics. So, web-based information system audit model is needed. Therefore, a web-based information system audit model was proposed to enhance the effectiveness of audit and to increase the quality. Audit check lists were applied based on three sets of existing information audit check framework. An audit point of time was defined as analysis, design, and implementation. An audit domain was defined as contents, design, and process. Moreover, audit viewpoint and inspection standards were defined by setting standards of process, product, and performance. Moreover, this paper proposes differences between an existing model of information system development methodology and web-based information system. It also deduced audit checklists according to audit domains for web-based information system audit. The deduced audit checklists were verified for its suitability by conducting surveys, and the modified audit inspection model, in which the deduced audit checklists were applied, was proposed.

  • The current information system audit merely inspects a web based information system by focusing on checking items that are extracted from structured and information engineering model and object-oriented component model. As a result, the checking item of web contents and design is inadequate. This paper aims to extract audit framework in order to strengthen the audit of web contents and design during the development of the web based information system and to suggest checking items based on audit framework. For this, the web development process and web site evaluation model were studied, compared, and analyzed with the current information system development audit. From a result of the survey, it was found that the adequacy of the suggested audit framework and audit checking items is above the average value. It is believed that the suggested audit framework is helpful for the audit of web based information system.

  • In the case of an agile-based project, it was inadequate to perform a comprehensive inspection and evaluation on the establishment and operation of an information system by performing audit only with the audit and inspection elements provided by the existing information system audit and inspection system. In particular, in the case of the test activity area, it was necessary to improve the test activity audit check items to comprehensively check the agile-based development process by applying the existing audit system. To this end, a test activity improvement check model of the agile methodology audit model was presented by applying the repetition concept, a characteristic of the agile methodology. In order to empirically verify the model of this study, a survey was conducted for auditors and designers/developers who have experience in performing agile-based projects and auditing information systems. As a result of the questionnaire on the integrated test and system test in the test stage, more than 70% of the respondents were found to be suitable. More than 80% of the respondents judged that it was appropriate as a result of the questionnaire on "improvement and regression test progress according to integrated test and system test results" and "integrated test and functional actions of components and subsystems".

  • Information system operation principles were recently established in order to provide high quality service and efficient operation audit of IT outsourcing. Operation managements are done based on these principles. Therefore, information operating management process, which refers to itself, is established. Information system operation audit requires a constant audit regularly, which is different from construction/development audit that is done only once. As operating management process changes, operation audit guidelines should be updated and improved. Therefore, this paper proposes IT outsourcing operation audit model with IT outsourcing achievement management as a focus. IT service domain was referred in order to propose information system operation audit model and check lists, which are based on IT outsourcing operation managements such as planning, making strategies, contract, service, and management. The deduced audit model and check lists verified suitability of the proposed model by experts' survey.

  • This thesis suggests fixed quantity model and detailed performance procedures of an information system audit. In addition, an identification of the check-items with high operating risk and factors that might lead to serious effects on the business are made. Then, this thesis proposes the information system audit model that can grant priorities. By using this model, the orderer can evaluate objectively with digitized mark. The model can improve the effectiveness, reliability, and objectivity of the audit by minimizing the discrepancies of different opinions about audit evaluation results between auditee and the orderer. The proposed model is adapted to an application system and audit projects of the database construction. As a result, the model has received an equal mark from the result of the general reviews, thus the propriety of the proposed model was verified.

  • This research is to suggest the factor which is effecting on the information system audit fidelity in the perspective of audit procurer, to develop the measure to evaluate it, to investigate the audit performance and project performance for comparison the audit fidelity between the audit teams. As the analysis results, we found that the audit service factors can be divided to the expert knowledge of auditor and the project attributes itself. It means these factors are the major measures for the audit fidelity. In this research, the hypothesis of this study model is verified throughout the factor and corelation analysis, and the structured equation model is applied. Analysis results show that all relations between the factors are significant statistically. The audit service factors has an effect on audit fidelity. Also the information system audit fidelity can be affect on the project performance, audit performance and customer satisfaction. So, in conclusion, we need to judge closely the audit service factors affecting the audit fidelity for the enhancement of the project performance, audit performance and customer satisfaction.

  • Recently, performance auditing system of governmen is carried out as most promising framework of government audit. Performance audit by the Board of Audit and Inspection of Korea involves assessing the causes and effects of government policies, programs, and Institutions with the criteria of economy, efficiency, effectiveness. Performance auditing will contribute to strengthening the values of objective assessments of whether public resources are responsibly and effectively managed to achieve intended results. Nevertheless, there seems to be a problems appears in implementation of audit. That is the problems of tendency return to legitimacy audit which is result from the lack of strong approach and methodology. So, this study purpose to developing stronger audit concepts and methods that add to the process and framework of traditional performance auditing system. First, this study evaluates the limitation of current performance auditing system with the perspective of systems thinking. Second, this study analyzes the process and method of current system and develop the conceptual model of the Dynamics Audit System using the system dynamics methodology, which focused on the appropriate auditing process and framework.

  • The study investigates and measures the impact of the emotional intelligence orientation on audit sustainability in Vietnam. Survey data for this research were collected from 260 auditors (CPAs) currently working in auditing firms, for the period from April 2020 to July 2020. In this study, we have built a model with two dependent variables (Emotional intelligence orientation and Audit sustainability) and six independent variables (Proactive audit vision, Continuous audit development, Dynamic audit experience, Audit environmental change, Stakeholder expectation pressure, Advocacy culture). The research methods used include Cronbach's Alpha test, exploratory factor analysis (EFA), confirmation factor analysis (CFA) and linear structural model analysis (SEM). The results showed that (1) Proactive audit vision, (2) Continuous audit development, (3) Dynamic audit experience, (4) Audit environmental change, (5) Stakeholder expectation pressure are positively related to emotional intelligence orientation. However, Advocacy culture is not positively related to Emotional intelligence orientation. The findings of this study suggest that emotional intelligence orientation positively impacts audit sustainability (similar to the findings by Thapayom, Ussahawanitchakit, & Boonlua, 2017, 2018 in Thailand). The results of this study provide a scientific basis for managers at auditing firms to make appropriate decisions to improve auditing activities in the coming years.

  • Purpose: In order to upgrade the energy performance of existing building, energy audit stage should be implemented first because it is useful method to find where the problems occur and know how much time and cost consumption for retrofit. In overseas researches, three levels of audit is proposed whereas there are no standards for audit in Korea. Besides, most studies use dynamic simulation in detail like audit level 3 even though the level 2 can save time and cost than level 3. Thus, this paper focused on audit level 2 and proposed the audit method with the simple linear regression analysis model. Method: Two parameters were considered for the simple regression analysis, which were the monthly electric use and the mean outdoor temperature data. The former is a dependent variable and the latter is a independent variable, and the building's energy performance profile was estimated from the regression analysis method. In this analysis, we found the abnormal point in cooling season and the more detailed analysis were conducted about the three heat source equipments. Result: Comparing with real and predicted models, the total consumption of predicted model was higher than real value as 23,608 kWh but it was the results that was reflected the compulsory control in 2013. Consequently, it was analyzed that the revised model could save the cooling energy as well as reduce peak electric use than before.
