The prevention of marine accidents has been a major topic in marine society and various policies and countermeasures has been developed, applied to the industries. Formal Safety Assessment is a structured and systematic methodology, aimed at enhancing maritime safety, including protection of life, health, the marine environment and property, by using risk and cost-benefit assessments. In addition, it provides a means of being proactive, enabling potential hazards to be considered before a serious accident occurs. In this paper, we has been screening and ranking of hazards using fuzzy structural modeling method and quantitative risk assessment for the ship's collision in the last 10 years marine accidents.

Based on ASME probabilistic risk assessment (PRA) and NEI PRA peer review guidance, we evaluate a human reliability analysis (HRA) in probabilistic safety assessment (PSA) for Korea standard nuclear power plants, Ulchin Unit 3&4, to improve it performed at under design. The HRA for Ulchin Unit 3&4 is assessed as higher than Grade I based on ASME PRA standard and as higher than Grade 2 based on NEI PRA peer review guidance. The major items to be improved identified through the evaluation process are the documentation, the systematic human reliability analysis, the participitation of operators in the works and review of HRA. We suggest the guidance on the identification and qualitative screening analysis for pre-accident human errors and solve some items to be improved using the suggested guidance.

Recently, with increasing the number of patients with head injury and cerebrovascular accident, there has been an increasing need for the useful assessment tools of brain dysfunction and it's localization. With the advances in the neuroscience since the mid-1970s, particularly in the areas of neuroanatomical tracing, neuroimaging, and improved behavioraltest design, it has been possible to develop a more precise understanding and localization of brain dysfunction. However, these equipments are not readily available in the private clinics and too expensive to use as a screening tool to all suspected patients with brain dysfunction. Although several screening tests such as Mini-Mental States Examination(MMSE) or Brief Cognitive Rating Scale(BCRS) are simple in use and useful for the brief assessment of brain dysfunction, these are also limited in using for localization of brain dysfunction because of their simplicity. With increasing need of the assessment tool which is able to localize the dysfunction more precisely in the clinical practice, we planned to develop the new assessment tool, the Bedside Neurocognitive Function Localization Test(BNLT) which is suitable for this purpose. The BNLT was designed to be utilized for localizing brain dysfunction effectively and readily in the clinical practice. We introduced the whole process of designing the BNLT in this manuscript.

Recently, there has been scientific discussion on the utility of -omics techniques such as genomics, proteomics, and metabolomics within toxicological research and mechanism-based risk assessment. Toxicogenomics is a novel approach integrating the expression analysis of genes (genomic) or proteins (proteomic) with traditional toxicological methods. Since 1999, the toxicogenomic approach has been extensively applied for regulatory purposes in order to understand the potential toxic mechanisms that result from chemical compound exposures. Therefore, this article's purpose was to consider the utility of toxicogenomic profiles for improved risk assessment, explore the current limitations in applying toxicogenomics to regulation, and finally, to rationalize possible avenues to resolve some of the major challenges. Based on many recent works, the significant impact toxicogenomic techniques would have on human health risk assessment is better identification of toxicity pathways or mode-of-actions (MOAs). In addition, the application of toxicogenomics in risk assessment and regulation has proven to be cost effective in terms of screening unknown toxicants prior to more extensive and costly experimental evaluation. However, to maximize the utility of these techniques in regulation, researchers and regulators must resolve many parallel challenges with regard to data collection, integration, and interpretation. Furthermore, standard guidance has to be prepared for researchers and assessors on the scientifically appropriate use of toxicogenomic profiles in risk assessment. The National Institute of Toxicological Research (NITR) looks forward to an ongoing role as leader in addressing the challenges associated with the scientifically sound use of toxicogenomics data in risk assessment.

Background: Recently symptoms-based screening questionnaires have gained attention for screening for a neuropathic pain component (NePC) in various chronic pain conditions. The present study assessed the usefulness of four commonly used NePC screening questionnaires including the Self-completed douleur neuropathique 4 (S-DN4), the ID Pain, the painDETECT questionnaire (PDQ), and the Self-completed Leeds Assessment of neuropathic Symptoms and Signs (S-LANSS) questionnaire in patients with chronic low back pain (CLBP) to assess the presence of NePC. Methods: This is a single-center cross-sectional study where patients with CLBP, with or without leg pain, were included. Participants were initially screened for NePC presence by a physician according to the regular practice, and later assessed using screening questionnaires. The diagnostic accuracy of these questionnaires was compared assuming the physician-made diagnosis as the gold standard. Results: A total of 215 patients with CLBP of which 164 (76.3%, 95% CI, 70.2-81.5) had a NePC were included. S-DN4, ID Pain, and PDQ have an area under the curve (AUC) > 0.8 indicating excellent discrimination. However, S-LANSS has an AUC of 0.69 (0.62-0.75), indicating low discrimination. S-DN4 has a significantly higher AUC as compared to ID Pain (d(AUC) = 0.063, P < 0.01) and S-LANSS (d(AUC) = 0.197, P < 0.01). But the AUC of S-DN4 does not significantly differ from that of PDQ (d(AUC) = 0.013, P = 0.62). Conclusions: S-DN4, ID Pain, and PDQ, but not S-LANSS, have good discriminant validity to screen for NePCs in patients with CLBP. Despite using all the tests, 20-30% of patients with an NePC were missed. Thus, these questionnaires can only be used as an initial clue in screening for NePCs, but do not replace clinical judgment.

Background: Mammography screening is a method for reducing breast cancer mortality in women over 40 years old. A participation rate of at least 70% is a prerequisite for screening programs. This study aimed at determining the participation rate of women in breast cancer screening in Iran. Materials and Methods: The study population in this prospective research consisted of 35 to 69 years old women in the villages and towns Kerman District, in 2013. The data were collected by a well-validated risk assessment questionnaire. The questionnaires were completed with the help of health workers and technicians in the health centers, who were trained on breast cancer screening program. Results: As a whole, 19,651 women were invited to complete the questionnaire, of whom 15,794 women (80.37%) completed it. In the urban region, of 3150 eligible women 2728 women (86.60%) participated in the study. The acceptance rates for mammography in rural and urban regions were 34.95% and 8.75%, respectively. Conclusions: Finally, 3.8% and 16.34% of 35 to 69 years old women in the urban regions were mammographed, respectively. Conclusion: The low participation of eligible women in breast cancer screening program alerts us against including the program in the health insurance package.

Background: To investigate the prevalence of and factors associated with performance of annual mammography by women above 40 years of age. Materials and Methods: This cross-sectional retrospective study was conducted at an oncology reference service in Southern Brazil from October 2013 to October 2014 with 525 women aged 40 years or older. Results: The prevalence of annual mammography was 54.1%; annual mammographic screening was performed for women without private medical insurance, who were under hormone replacement therapy and who had used contraception in the past. An association was found between non-performance of breast clinical and self-examination and non-performance of mammographic screening. Conclusions: Use of mammography for breast cancer screening in the public health care setting proved to be accessible; nevertheless, the proportion of screened women was low, and they exhibited poor adherence to the basic measures of care recommended for breast assessment. Thus, control of breast cancer requires implementing actions targeting the population most vulnerable to non-adherence to screening in addition to continuously monitoring and assessing that population to reduce the prevalence of this disease.

Purpose: This study aimed at the effectiveness to investigate the performance of evidence-based pain assessment and management guidelines. Methods: Participants were 140 nurses at the med-surgical units. Data were collected in early July, 2014 using Registered Nurses Association of Ontario (RNAO) guideline (2007) revised and validated by Hong and Lee (2012) and analyzed by descriptive statistics, t-test, ANOVA using SPSS/WIN18.0. Results: The score of performance of pain assessment guideline was higher than the score of pain management. Categories with high score were pain screening, parameter of pain assessment, documentation, assessment of opioids side-effects, and record of pain caused intervention. Categories with low score were comprehensive pain assessment, multidisciplinary communication, establishing a plan for pain management, consultation and education for patients and their families, and education for nurse. Non-pharmacological management was the lowest one. Conclusion: Assessing and managing pain is a complex phenomenon. It might be useful if institutions host training programs to ensure that nurse are better able to understand and implement pain assessment and management. Since non-pharmacological management is less likely to be used by nurses it may be helpful to include these methods in a training program.
