  • During the last ten years, the need has been increased for reducing maintenance cost for aged equipments and ensuring safety, efficiency and profitability of petrochemical and refinery plants. RBI (Risk Based Inspection) methodology is one of the most promising technologies satisfying the need in the field of integrity management. In this study, a user-friendly software, realRBl for RBI based on the API 581 code was developed. This software has modules for evaluating qualitative and semi-quantitative risk level, analyzing quantitative risks using the potential consequences of a failure of the pressure boundary, and assessing the likelihood of failure. A quantitative analysis was performed for 16 columns in a domestic NCC (Naphtha Cracking Center) plant whose operating time reaches about 12 years. Each column was considered as two equipment parts by dividing into top and bottom. Generic column failure frequencies were adjusted based on likelihood data. After determining release rate, release duration and release mass for each failure scenario, flammable/explosive and toxic consequences were assessed. Current risks for 32 equipment parts were evaluated and risk based prioritization were determined as a final result.

  • The risk enlargement of cyber infringement and hacking is one of the latest hot issues. To solve the problem, the research for Security Risk Analysis, one of Information Security Technique, has been activating. However, the evaluation for Security Risk Analysis has many burdens; evaluation cost, long period of the performing time, participants’ working delay, countermeasure cost, Security Management cost, etc. In addition, pre-existing methods have only treated Analyzing Standard and Analyzing Method, even though their scale is so large that seems like a project. the Analyzing Method have no option but to include assessors’ projective opinion due to the mixture using that both qualitative and quantitative method are used for. Consequently, in this paper, we propose the Security Risk Analysis Methodology which manage the quantitative evaluation as a project and use Case-Based Reasoning Algorithm for define the period of the performing time and for select participants.

  • The purpose of this study was to investigate the causes of managerial failure in small apparel retailers by using the qualitative research method. The study was performed by interviews from thirteen owners/managers who experienced failure as small apparel retailers from November 2003 to February 2004. The causes of failure in the small apparel businesses were human related problems, marketing strategy problems, marketing mix, weak managerial ability, and business environment related problems. Of special interest was causes such as incomplete legal documents with franchisers, unexpected tax investigation from the office of National Tax Administration(NTA), sexual discrimination for women owners, and incapable risk management. It is interesting to note that tax investigation by NTA and sexual discrimination in the business custom were shown as the main causes of business failure in Korea.

  • Purpose: This study aimed to identify the characteristics of patient safety incidents (PSIs) related to nursing and to provide primary data for preventing the recurrence of similar incidents. Methods: This secondary analysis study included damage claims rulings filed for clinical negligence from 2014 to 2018 that contained the keyword 'nurse'. It excluded judgments irrelevant to nursing care and in which clinical negligence or causal damages were overruled. A total of 93 cases were analyzed. The characteristics of PSIs were derived through descriptive statistics, and two instances of nursing-related PSIs were examined by qualitative content analysis focusing on root causes. Results: The analysis of PSIs related to nursing suggested that the medical institutions where the PSIs occurred most frequently were hospitals, and the most common types of PSIs were medication, surgery, and treatment/procedure, in that order. In addition, it indicated that nursing-related PSIs occurred most frequently in general wards during the day shift, with the most common related nursing practice being managing potential risk factors. The qualitative analysis showed that careless monitoring and institutional inertia were causes of PSIs. Conclusion: To prevent nursing-related PSIs, nurses need to individually monitor and assess patient conditions. In addition, support should be accompanied by the improvement in the systems in place aimed at preventing the recurrence of nursing-related PSIs at the institutional and national level, such as securing appropriate nursing personnel and improving labor conditions.

  • Objectives: Balancing benefits and risks through the drug life cycle has been discussed for many decades. The objective of this study was to review the processes and tools currently proposed for benefit-risk assessment of medicinal drugs. It aimed to establish scientific and efficient drug safety management system based on the synthetic analysis of benefit-risk evidence. Methods: We conducted a review of exiting literatures published by regulatory agencies or initiatives. Not only quantitative methodologies but also qualitative method were compared to understand their key characteristics for the benefit and risk assessment of drugs. Results: Recently, benefit-risk assessments have more structured approaches to decision making as part of regulatory science. Regulatory agencies such as European Medicines Agency, FDA have prepared plans to apply benefit-risk assessment to regulatory decision making. Also many initiatives such as IMI (Innovative Medicine Initiative) have conducted research and published reports about benefit-risk assessment. For benefit-risk assessment, four kinds of methods are necessary. Frameworks such as BRAT (Benefit Risk Action Team) framework, PrOACT-URL provide guidance for the whole process of decision-making. Metrics are measurements of risk benefit. The estimation techniques are methods to synthesis and combine evidences from various sources. The utility survey techniques are necessary to explicit preferences of various outcome from stakeholders. Conclusion: There is the lack of widely accepted, validated model for benefit-risk assessment. Nor there is an agreement among academia, industry, and government on methods for the quantitative valuation. It is also limited by available evidence and underlying assumptions. Nevertheless, benefit-risk assessment is fundamental to improve transparency, consistency and predictability for decision making through the structured systematic approaches.

  • A conceptual site model is used to support decision-making of response strategy development, determination, and implementation within a risk-based contaminated site management system. It aims to provide base information of the relevant site characteristics and surface/subsurface conditions in order to understand the contaminants of concern and the associated risk they pose to the receptors. This study delineated the technical details of conceptual site model development, and discussed the possibility of applying it in domestic subsurface contamination management. Conceptual site models can be developed in various formats such as tables, diagrams, flowcharts, and figures. Contaminated sites are managed for a long period of time following the steps of investigation, remediation design, remediation, verification, and post-remedation management. The conceptual site model can be enhanced in each stage of the contaminated site management based on the continuously updated information on the site's subsurface environment. In the process of enhancement for conceptual site model, precision is gradually improved, and it can evolve from a conceptual and qualitative form to a more quantitatvive and three-dimensional model. In soil pollution management, it is desirable to incorporate the conceptual site model into the soil scrutiny system to better assess the current status of the contaminated site and support follow-up investigation and management.
