The FMEA is a widely used technique to pre-evaluate and avoid risks due to potential failures for developing an improved design. The conventional FMEA does not consider the possible time gap between occurrence and detection of failure cause. When a failure cause is detected and corrected before the failure itself occurs, there will be no other effect except the correction cost. But, if its cause is detected after the failure actually occurs, its effects will become more severe depending on the duration of the uncorrected failure. Taking this situation into account, a risk metric is developed as an alternative to the RPN of the conventional FMEA. The severity of a failure effect is first modeled as linear and quadratic severity functions of undetected failure time duration. Assuming exponential probability distribution for occurrence and detection time of failures and causes, the expected severity is derived for each failure cause. A new risk metric REM is defined as the product of a failure cause occurrence rate and the expected severity of its corresponding failure. A numerical example and some discussions are provided for illustration.

This study is to introduce a comprehensive framework of a crisis management system developed at a prominent hospital in South Korea. Throughout recent decades, especially in the recent years, the way in which to cope with both internal and external challenges has been one of the most critical issues. Since the incident management system in the U.S. is acknowledged as the most advanced crisis management model in the world, a portion of this study refers to the Hospital Incident Command System(HICS) provided by the California Emergency Medical Services Authority(EMSA). Nevertheless, the framework suggested in this article was designed based on a distinctive Korean hospital setting. The main contents of this study are as follows; categorization of each type of crisis, organization of a crisis management team in a non-crisis or crisis state, crisis assessment by life cycle stage, and establishment of crisis management protocol. Even though many types of crises are unspecified, those can be categorized into external crisis, medical crisis, and utility & activity failure. A crisis management organization should be operated and consisted differently- depending on a crisis or non-crisis situation. From a life-cycle perspective, the range by which the crisis should be managed extends from pre-stage to post-stage of the crisis. It is important to set proper scenarios and manuals by crisis type to develop a crisis management framework of high quality. With continuous efforts, hospitals can prepare for the uncertainty to better concentrate on core business operations.

Background: Since 2019, the Ministry of Environment has implemented a seasonal fine dust management system from December to March, targeting high PM_2.5 levels with the aim of reducing PM_2.5 concentrations and protecting public health. The focus of improving the seasonal management system lies in the atmospheric PM_2.5 levels. Considering the primary goal of protecting public health, it is necessary to analyze the policy effects from an exposure perspective rather than a concentration-based approach. Objectives: This study aims to quantitatively assess the improvement of indoor PM_2.5 levels and the health impacts of the seasonal management system by comparing the periods before and during its implementation in residential environments. Methods: PM_2.5 concentrations within residential environments in a metropolitan area were measured using an optical particle counter (IAQ-C7, K-weather, Ltd, Korea) at one-minute intervals during the pre-implementation period (November 21~25, 2022) and during the implementation period (December 19~23, 2022). Based on the measured PM_2.5 concentrations, a quantitative evaluation of cancer and mortality risks was conducted according to age and gender. Results: The results of comparing indoor and outdoor PM_2.5 concentrations before and during the implementation of the seasonal management system showed a decrease of approximately 56.6% and 47.9%, respectively. Health risk assessments revealed that both the safety-limit-based and safety-target-based Hazard Quotients (HQ) exceeded the threshold of 0.1 for children under 19 years of age, both before and after the implementation. The mortality risk decreased by approximately 47.9% after the implementation, with children aged 0-9 showing the highest mortality risk at 0.9%. Conclusions: The findings of this study confirmed the positive health impacts of the seasonal management system across all age groups, particularly children under 19 who are more vulnerable to fine dust exposure.

Slope failures are happen to natural disastrous when they occur in mountainous areas adjoining highways in Korea. The accidents associated with slope failures have increased due to rapid urbanization of mountainous areas. Therefore, Regular maintenance is essential for all slope and conducted to maintain road safety as well as road function. In this study, we take priority of making a database of risk factor of the failure of a slope before assesment and analysis. The purpose of this paper is to recommend a standard of Slope Management Information Sheet(SMIS) like as Hazard Map. The next research, we suggest to pre-estimated model of a road slope using Logistic Regression Model.

Microscopic surgery of the larynx normally have a low recurrence rate. However, once they do recur, it is uneasy to manage recurrent diseases. Recurrence is often the result of inappropriate postoperative care and voice management. Out of the 764 patients operated for benign inflammatory laryngeal diseases, we have conducted a clinical analysis of 54 cases who have had at least one episode of recurrence after the initial treatment with laryngomicrosurgery (7.1% of recurrence rate). High risk groups for recurrence were determined, and they were related to cigarette smoking, alcohol intake, laryngopharyngeal reflux. From our experience and literature review, we conclude that pre- and postoperative patient education concerning these risk factors and voice usage Is of critical need to prevent recurrence of inflammatory laryngeal lesions after laryngomicrosurgery.

Atrial fibrillation (AF) is the most common arrhythmia associated with the risk of morbidity and mortality in clinical patients. AF is considered as an arrhythmia type that develops and progresses through close connection with cardiac structural arrhythmogenic substrates. Since the introduction of catheter ablation-mediated electrical isolation of arrhythmogenic substrates, cardiac imaging indicates improved treatment outcome and prognosis with appropriate candidate selection, ablation catheter guidance, and post-ablation follow-up. Currently, cardiac computed tomography (CCT) and cardiovascular magnetic resonance (CMR) imaging are essential in the case management of AF at both pre-and post-procedural stages of catheter ablation. In this review, we discuss the roles and technical considerations of CCT and CMR imaging in the management of patients with AF undergoing catheter ablation.

Recently, the automotive industry has been introduced to ISO 26262 in November 2011 to address the necessity of safety risk from sensor to actuator by providing guidance in the form of requirements and processes. The malfunctioning behaviour of these systems could have significant impact on the safety of humans and/or the environment. Most of the modern automobiles are equipped with embedded electronic systems which include lots of Electronic Controller Units (ECUs), electronic sensors, signals, bus systems and coding. Due to the complex application in electrical, electronics and programmable electronics, the need to carry out detailed safety analyses which focuses on the potential risk of malfunction is crucial for automotive systems. In this paper, the international trends on pre and post introduction of ISO 26262 through publications will be analyzed as well as to take a glimpse in the activities for implementing this standard by the automotive manufacturers. The issues and challenges which have been occurring from implementing this standard also will be highlighted.

Cervical cytology remains the principal screening method to detect pre-invasive and invasive cervical lesions. Management of abnormal cervical cytology depends on the risk of encountering a significant cervical lesion or high-grade cervical disease. These risks may vary in different areas across the country. Thus, determining the rate of significant cervical lesion associated with each type of abnormal cervical cytology in each area is of critical importance for designing area-specific management approach. This review was conducted to evaluate the rate of high-grade cervical disease among Thai women with abnormal cervical cytology. A relatively high incidence of underlying significant lesions including invasive disease was demonstrated even in those having only minimal smear abnormality. This baseline information is crucial and must be taken into consideration in management of women with abnormal cytological screening to achieve the goals of comprehensive cervical cancer control in Thailand.

Objectives: This study evaluated dietary behavior and nutritional status according to the metabolic syndrome status in Korean menopausal women. Methods: The subjects were 1,392 menopausal women aged 50 to 64 who took part in the Korea National Health and Nutrition Examination Survey of 2016 and 2017. Subjects were classified into normal (NOR) group, pre-metabolic syndrome (Pre-MetS) group, and metabolic syndrome (MetS) groups according to the number of metabolic syndrome risk factors present. Results: The overall prevalence of metabolic syndrome was 33.7%. Using the NOR group as a reference, the odds of belonging to the MetS group in Model 1 adjusted for age were higher at 53% (OR = 1.53, 95% CI:1.011-2.307) for 'not used' subjects compared to 'used' subjects of the nutrition labeling system. Using the NOR group as a reference, every 1g increase in the intake of monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) decreased the odds of belonging to the MetS group in Model 1 adjusted for age by 3% (MUFA, OR = 0.97, 95% CI:0.946-0.991; PUFA, OR = 0.97, 95% CI:0.942-0.993). Conclusions: These results suggest that to reduce the number of risk factors of metabolic syndrome in menopausal women, nutritional education should emphasize the adequate intake of riboflavin, unsaturated fatty acids, protein, and calcium, and also encourage the recognition and use of nutritional labeling. Results of this study are expected to be utilized as basic data for the health management of menopausal women.
