Purpose: The proficiency test was conducted to assess the performance of the dosimetry audit service provider in the readout practice of the dose delivered to patients in medical institutions. Methods: A certain amount of the absorbed dose to water for the high-energy X-ray from the medical linear accelerator (LINAC) installed in the Korea Research Institute of Standards and Science (KRISS) was delivered to the postal dose audit package given by the dosimetry audit service provider, in which the radio-photoluminescence (RPL) glass dosimeters were mounted. The dosimetry audit service provider read the RPL glass dosimeters and sent the readout dose value with its uncertainty to KRISS. The performance of the dosimetry audit service provider was evaluated based on the E_n number given in ISO/IEC 17043:2010. Results: The evaluated E_n number was -0.954. Based on the ISO/IEC 17043, the performance of the dosimetry service provider is "satisfactory." Conclusions: As part of the conformity assessment, the KRISS performed the proficiency test over the postal dose audit practice run by the dosimetry audit service provider. The proficiency test is in line with confirming the traceability of the medical institutions to the primary standard of absorbed dose to the water of the KRISS and ensuring the confidence of the dosimetry audit service provider.

This paper describes how to derive audit criterion, audit domain, detail technology, and functional check items which are core of hospital information system, consisting of OCS, EMR, and PACS. Using the check items listed above, we investigated the objective validity for the construction audit of hospital information system. As a result, the derived audit criterion, audit domain, detail technology, and functional check items were verified as check items for audit. Since using the current audit check items of public area is insufficient to construct efficient, reliable, and stable hospital information system, we suggest adopting the hospital information system audit area, audit check items, and process that are presented in this paper.

I have taught various case audit underwriting methods to underwriters for many years. Underwriting requires specialized medical knowledge and experience of comprehensive individual risk analysis. Decisions in individualized underwriting depend on the insurance company's management philosophy and vision, marketing strategies, culture, product line etc. They also depend on the information acquired through proposal forms, inspection reports, laboratory results and disclosures. Underwriters match this acquired information to each insurance product, search appropriate medical resources, assess the probabilities of future claims, and decide what, if any, further medical information should be gathered. Sources include doctors' reports, medical records, biopsies, blood and urine tests, CT, MRI, Holter monitoring, sonography etc. Insurance medical directors help and teach underwriters to analyze individual medical risks and make effective.

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".

As a result of the compulsory of information system audit and a rise in audit demand, the quality improvement of information system audit is being emphasized. However, since the current information system audit heavily depends on the auditor's experience, skill, and subjective judgments, it incurs distrust in the objectivity and reliability of audit results from audit interest person. Furthermore, so far research activities aimed at securing the objectivity and reliability of audits have not been adequately carried out. Therefore, this paper presents a quantitative method for information system audit evaluation in order to contribute to the quality improvement of overall information system audit through securing compliance, objectivity, and reliability of information system audit. The quantitative method is largely composed of two sectors, such as evaluation areas and items, scores calculation for evaluation items, and can generally apply the information system audit standard to information system audit evaluation.

Purpose: The purpose of this study is to introduce the Institutional Review Board (IRB) member-based internal audit method performed at A University Hospital, a secondary medical institution, and to identify the differences in audit results according to the characteristics of each auditor and the factors affecting the internal audit results. Furthermore, we will find out what needs to be improved in the internal audits to achieve Quality assurance (QA) objectives for human subject research conducted in medical institutions. Methods: The auditors were divided into group A (IRB member belonging to institution A) and group B (clinical trial QA administrator belonging to other institutions) and independently inspected the 2 studies using the same internal audit checklist (consisting of 11 domains, 130 items), and the differences in the internal inspection checklists written by each auditor were compared and analyzed. Results: In the case of audit for the study 1, the number of missing checklists is 1 for group A and 0 for group B, and the number of the matters to be pointed out is 1 for group A and 12 for group B. In the case of audit for the study 2, the number of missing checklists is 2 for both A and B, and the number of points is 5 for A and 4 for B. The differences in the internal audit results written by each auditor that the authors verified are summarized as follows. First, there were more comments from group B auditor than from group A auditor. Second, the results may vary because each auditor has different criteria for evaluating the appropriateness of an item. Third, there are cases where the questions on the checklist are vague or the definition is not clear, so they have the same opinion but check it with different answers. Fourth, if the auditors make a mistake when filling out the checklist, it causes to led to different the results. Conclusion: We propose the following items that should be improved in order to conduct consistent and efficient internal audits. First, it is necessary to test the tool in order to carry out reliable and consistent internal audits. Second, it is necessary to complete specialized training related to internal audit before conducting internal audit. Third, before notifying the audit results, it is necessary to have a procedure or a final review system to check whether the audit contents are appropriate. Fourth, Institutional support is needed to recruit specialized personnel for internal audits.
