According to Railway Safety Act, Korea Transportation Safety Authority (KOTSA) has been entrusted with 'Integrated Railroad Safety Audit (IRSA) and has implemented the safety audit to the railroad operation agencies such as Korea Railroad (KORAIL) and the railroad facility management organization such as the Korea Rail Network Authority (KR Network). The target of IRSA is to establish the effective rail safety management system and to raise the safety level of the railroad operation and facility agencies by checking synthetically their performance of safety duties with sincerity according to the Railway Safety Act. Even though newly introduced IRSA is conducted smoothly, it is necessary to study the methodology and criteria of the state's safety audit system. The purpose of this paper is to improve the efficiency of IRSA by the comparative research between IRSA and other similar safety audit system and to establish the consecutive improvement concept of IRSA. Second purpose is to confirm the effectiveness of IRSA by the analysis of the relationship between audit results and the safety level of the rail operation agencies.

Purpose - The purpose of this study is to expand the taxpayer's rights protections, which are covered in the previous studies, and to suggest ways to increase tax inspection efficiency as a way to induce fidelity reporting under the final tax return system and to lower tax compliance costs. Design/methodology/approach - The tax audit is a necessary system for the taxpayer to induce self-reporting in a sincere manner, but it is necessary to harmonize the realization of fair taxation and the rights of taxpayers because it is likely to infringe taxpayer rights in the process. Research implications or Originality - The purpose of this study is as follows. First, the government will seek ways to improve tax investigations to strengthen the protection of taxpayers' rights by increasing the fairness and procedural transparency of the current tax investigation system, as pointed out in the National Tax Administration Reform T / F. Second, we will consider ways to enhance the effectiveness of tax audit as a means of inducing faithful tax in Korea's tax system, which assumes sincere taxpayers.

Auditing plays a very important role in the process of developing and managing good quality software. The software developing proces should be audited precisely especially in the test phase. Up to the present, because auditing has depended on the auditor's experience of developing and auditing software, it has been impossible to audit objectively. It is limited to audit systematically and objectively because auditing process isn't systematized. In this paper, the auditing model to solve several problems in present auditing is suggested, a test phase audit system is developed, and the system is applied to the actual auditing process. Consequently, software administrators can establish effective software management, software developers can be supported by a highly reliable and quality software development tool, and auditors can be offered an objective audit standard.

In this study an evaluation method is proposed, with the strong relationship between the ante and post audit works evaluation. The ante evaluation does in general and systematic ways, with past audit results and proposals. The criteria-based evaluation is used for the audit activities and outputs. The critical success factors for the projects applies to the activities evaluation and product evaluation framework to the output. The ante and post evaluation have the cross evaluation items to be the whole and continuous one. Eighteen common evaluation items are derived, with their own evaluation elements in detail, which have only differences of the actually done and expectations between the ante and post. The proposed evaluation makes the ante and post one to be related with each other in a systematic and objective ways, to enhance the reliability of audit results and effectiveness of the audit.

현재 대부분의 상용 운영체제는 운영체제의 보안성을 높이기 위하여 높은 수준의 감사 기능을 제공한다. Linux의 성능 및 안정성은 기존 상용 운영체제에 뒤떨어지지 않지만, 감사 기능을 거의 제공하지 못하고 있다. Linux를 서버 운영체제로 사용하기 위해서는 C2 수준 이상의 보안성을 필요로 하며, 이를 만족시키기 위해서는 시스템 콜에 대한 감시와, 감사 이벤트가 요구된다. 본 논문의 LxBSM은 Linux 커널에서 C2 수준의 감사 기능을 제공하는 커널 모듈이다. LxBSM은 SunShield BSM의 감사 자료와 호환되는 C2 수준의 감사 자료를 제공하며, 동적 커널 모듈(Loadable Kernel Module) 방식으로 구현되어 운용성을 높였다. 또한 사용자 프로세스에 대한 감사 자료를 생성함으로써, 기존의 Linux 기반 감사 모듈보다 풍부한 감사 자료를 제공한다. 파이프와 파일로 감사 자료의 출력이 가능하여 감사 자료를 활용하는 침입 탐지 시스템의 연계성을 높였다. LxBSM의 성능을 측정한 결과, fork, execve, open, close와 같이 감사 자료를 생성하는 시스템 콜이 호출될 때의 응답 시간은 지연되었으나, 그 외의 다른 성능 감소 현상은 나타나지 않았다.

The purpose of this study is to devise proper plans for sustainable energy management in schools through applying school eco-audit to energy field. This study is performed by literature review and the analysis of case study. This study analyzes the energy-saving model school according to the three cores of eco-audit such as school administration system, teaching-learning method, and ecological policy, and the result of the study is as followings. First, according to the analysis of school administration system for energy education programs, the participation of all the school staff is very low, and the democratic decision-making system is unsatisfactory. Second, according to the analysis of teaching-learning method, the program is mainly managed by teacher-oriented method not by learner-oriented one. The effect on the education of energy-saving program is a little improved in cognitive area, but is insufficient in affective area. Third, in the aspect of the ecological policy, the practical energy-saving effect in schools is unsatisfactory, and shows the difficulty of continuing application of the program. Consequently, it is desirable to integrate the energy-saving program with the eco-audit for sustainable energy management in schools. Implementation of the energy eco-audit in schools for the sustainable development education as teaching-learning method could achieve extended effect for the earth environmental conservation.

This study aims to examine (1) the association between the chief executive officer tenure and audit quality, (2) the relationship between chief executive officer duality and audit quality, (3) the association between board independence and audit quality, (4) the relationship between board size and audit quality, and (5) the role of controlling variables (client size, leverage debt, and business complexity) in controlling these relationships. The research sample includes 325 financial reports from manufacturing firms listed in Amman Stock exchange over the 2014-2018 period. The study relationships are tested by using logistic regression. The results revealed a negative relationship, but not significant between CEO tenure and independent directors with audit quality. In addition, the results showed there is a negative effect of CEO duality on audit quality; also the results revealed that there is a statistically significant effect on the board of directors (board size) on the AQ. In general, the coefficient estimates of controlling variables show that client size and leverage debt positively affect audit quality, and on the contrary, business complexity has an insignificant positive relationship with audit quality. The summary of the study findings play an active role to external auditor opinion on business practice in towered the corporate governance system.

To cope with the change of railway safety environment and to prevent the catastrophic accident, the railway safety management system was established through the legislation of railway safety rules. And to audit and evaluate the accomplishment of railway safety rules by the railway operators, the Integrated Railway Safety Audit System(IRSAS) has been conducting. This study find out the strategy to stabilize the IRSAS by applying Theory of Constraints(TOC) Thinking Process. For meeting the IRSAS's goal of effective levelling up of railway safety, the two necessary conditions, 1)the secure of substantial safety through the IRSAS and 2)the execution of efficient IRSAS, should be fulfilled. Estimated undesirable effects(UDEs) from the IRSAS were identified, and 3 of them were selected for creating the requisite conflict clouds. Entities from these conflict clouds were synthesized into a core conflict cloud that foamed the base of Current Reality Tree. The strategic direction for change extracted from the conflict cloud is the reinforcement of IRSAS preparation system including the level up of operator's self audit, the deepening of preliminary survey, the establishment of complementing system of audit check list and the build up of auditor's specialization. These injection were logically validated via a Future Reality Tree and expected to be confirmed by further progressing of IRSAS.
