Objectives: Pregnant women and those of childbearing age are a well-known sensitive population for human mercury exposure. Therefore, this study was conducted to reveal and enrich basic information for effective risk communication to reduce the adverse health effects of mercury exposure. Methods: A self-administered questionnaire survey was conducted among 432 women aged 19-44 years, recruited conveniently from three different regions (Busan, Ulsan, and Gumi City). Questionnaires were developed by referring to the existing literature and through expert meetings. They consisted of questions on knowledge and awareness of mercury exposure risks, health information literacy, and relevant information. Results: The rank of perceived mercury health risk score was 5 out of 16 environmental risk factors, and 41.7% of participants thought that even a very little mercury could lead to an adverse health effect. Although 90.3% of participants had knowledge that childbearing age women must pay attention to fish intake, only 38.9% of participants knew the national fish intake guidelines for pregnant women. Conclusions: Although risk perception and knowledge of pregnancy-specific features of mercury were relatively high, the national fish intake guidelines were still not well recognized. It could be an effective strategy to provide evidence-based and targeted information articulated by professionals using internet based communication channels.

The study aims to analyze the compliance and non-compliance of the Korean health authorities regarding WHO's mask use recommendations following the spread of Covid-19, and to suggest the limitations and implications of the recommendations in the prevention of epidemics by deriving the causes of non-compliance with the results of alternative options. To this end, documents related to masks at home and abroad are reviewed, and WHO's mask recommendations and the Korean health authorities' mask guidelines are targeted for analysis. The analysis results are as follows. First, Korea's health authorities have basically accepted and applied WHO's "limited mask user perspective" in two recommendations. Second, Korea's health authorities have implemented differently from WHO mask recommendations due to the lack of supply and demand of masks. Third, Korea's health authorities were able to succeed in the initial prevention of Corona 19 based on the stabilization of the mask supply. Fourth, in the WHO mask recommendations, mask user restriction resulted in partial errors as a recommendation. The implication derived from the analysis is that even international recommendations based on medical evidence need to be allowed to follow autonomous guidelines according to the country's quarantine situation and competence, rather than strict adherence to international rules, in the infectious disease pandemic situation.

Evidence of liquefaction during the 2017 Pohang earthquake has highlighted the urgent need to evaluate the current seismic design standard for liquefaction in Korea, particularly the liquefaction triggering standard. With the simplified method, which is the most popular method for evaluating liquefaction triggering, the factor of safety for liquefaction triggering is calculated via the cyclic stress ratio (CSR) and the cyclic resistance ratio (CRR). The parameters in the CSR and CRR have undergone changes over time based on new research findings and lessons learned from liquefaction case-histories. Hence, the current design standard for liquefaction triggering evaluation in Korea should also reflect these changes to achieve seismic safety during future earthquakes. In this study, liquefaction susceptibility criteria were discussed initially and this was followed by a review of the current liquefaction triggering codes/guidelines in other countries and Korea. Next, the parameters associated with the CSR such as the maximum ground acceleration, stress reduction factor, magnitude scaling factor, and overburden correction factor were discussed in detail. Then, the evaluation of the CRR using the SPT N-value and CPT qc-value was elaborated along with overburden and clean-sand correction factors. Based on this review of liquefaction triggering evaluation standards, recommendations are made for improving the current seismic design standard related to liquefaction triggering in Korea.

Purpose : Selective functional movement assessment(SFMA) is a movement-based assessment tool designed for clinicians to diagnose and treat pain and functional physical problems. This concept is used for assistance in occupations related to movement, including clinical medical personnel, such as physical therapists, physical education instructors, and athlete coaches. Although this concept is widely used by clinicians, research and scientific proofs are relatively insufficient. This study aimed to review the literature on the understanding, reliability and effectiveness of SFMA, and to consider its role in the future of rehabilitation. Methods : In this review, a total of nine articles were selected according to the eligibility criteria of three major thesis topics. The main topics covered in the literature are reliability and effectiveness of clinical use of SFMA. To gather research articles, we searched official term 'Selective Functional Movement Assessment'. Among the searched 60 studies, nine were mentioned in this study that contained overlapping information and matched our desired topic. We reviewed four reliability analyses, four case reports, and one experimental study. Results : Reliability has an intermediate degree between high raters and within raters. The validity of the SFMA system is influenced by a combination of experience and logic; hence, further improvement is needed. Therefore, if the intervention was effective based on the diagnosis result, then biomechanical evidence is necessary to further support the claim. Conclusion : In future research, to use SFMA as a diagnostic tool with high accuracy, it is necessary to improve the reliability of the main problem through breakout, support for guidelines and validity and efficiency.

We analyzed the responses of 152 science-gifted high school students by surveying the status and recognition of writing and keeping laboratory notebooks to develop guidelines and education plans. Science-gifted students did not write laboratory notes diligently, despite recognizing that it is crucial to do so. Mentors also tended not to provide faithful guidance and inspection. There was an insufficient practice in using research evidence in laboratory notebooks, such as including names and dates for authentication. In addition, while a high ratio of students owned their own laboratory notebooks, there was not a high level of recognition regarding the retention period, ownership, and responsibility. Based on these results, we propose suggestions for improving educational institutions for gifted students in science. First, it is necessary to strengthen the guidance for science-gifted students to faithfully write laboratory notebooks. Second, education on writing laboratory notebooks should be provided. Third, science-gifted high schools should prepare regulations for the management of lab notes and conduct education based on them.

Dentoalveolar (DA) trauma, which can involve tooth, alveolar bone, and surrounding soft tissues, is a significant dentofacial emergency. In emergency settings, physicians might lack comprehensive knowledge of timely procedures, causing delays for specialist referral. This systematic review assesses the literature on isolated DA fractures, emphasizing intervention timing and splinting techniques and duration in both children and adults. This systematic review adhered to PRISMA guidelines and involved a thorough search across PubMed, Google Scholar, Semantic Scholar, and the Cochrane Library from January 1980 to December 2022. Inclusion and exclusion criteria guided study selection, with data extraction and analysis centered on demographics, etiology, injury site, diagnostics, treatment timelines, and outcomes in pediatric (2-12 years) and adult (>12 years) populations. This review analyzed 26 studies, categorized by age into pediatrics (2-12 years) and adults (>12 years). Falls were a common etiology, primarily affecting the anterior maxilla. Immediate management involved replantation, repositioning, and splinting within 24 hours (pediatric) or 48 hours (adult). Composite resin-bonded splints were common. Endodontic treatment was done within a timeframe of 3 days to 12 weeks for children and 2-12 weeks for adults. Tailored management based on patient age, tooth development stage, time elapsed, and resource availability is essential.

Gadoxetate magnetic resonance imaging (MRI) is widely used in clinical practice for liver imaging. For optimal use, we must understand both its advantages and limitations. This article is the outcome of an online advisory board meeting and subsequent discussions by a multidisciplinary group of experts on liver diseases across the Asia-Pacific region, first held on September 28, 2020. Here, we review the technical considerations for the use of gadoxetate, its current role in the management of patients with hepatocellular carcinoma (HCC), and its relevance in consensus guidelines for HCC imaging diagnosis. In the latter part of this review, we examine recent evidence evaluating the impact of gadoxetate on clinical outcomes on a continuum from diagnosis to treatment decision-making and follow-up. In conclusion, we outline the potential future roles of gadoxetate MRI based on an evolving understanding of the clinical utility of this contrast agent in the management of patients at risk of, or with, HCC.

Purpose: Despite the numerous protocols and evidence-based guidelines that have been published, application of the therapeutics to eligible patients is limited in clinical settings. Therefore, a rounding checklist was developed to reduce errors of omission and the implementation results were evaluated. Methods: A checklist consisting of 12 components (feeding, analgesia, sedation, thromboembolic prophylaxis, head elevation, stress ulcer prevention, glucose control, pressure sore prevention, removal of catheter, endotracheal tube and respiration, delirium monitoring, and infection control) was recorded by assigned nurses and then scored by the staff for traumatized, critically ill patients who were admitted in the trauma intensive care unit (ICU) of Dankook University Hospital for more than 2 days. A total of 170 patients (950 sheets) between April and October 2016 were divided into 3 periods (period 1, April to June; period 2, July to August; and period 3, September to October) for the analysis. Questionnaires regarding the satisfaction of the nurses were conducted twice during this implementation period. Results: Record omission rates decreased across periods 1, 2, and 3 (19.9%, 12.7%, and 4.2%, respectively). The overall clinical application rate of the checklist increased from 90.1% in period 1 to 93.8% in period 3. Among 776 (81.7%) scored sheets, the rates of full compliance were 30.2%, 46.2%, and 45.1% for periods 1, 2, and 3, respectively. The overall mean score of the questionnaire regarding satisfaction also increased from 61.7 to 67.6 points out of 100 points from period 1 to 3. Conclusions: An ICU rounding checklist could be an effective tool for minimizing the omission of preventative measures and evidence-based therapy for traumatized, critically-ill patients without overburdening nurses. The clinical outcomes of the ICU checklist will be evaluated and reported at an early date.
