Objectives: The purpose of this study was to analyze efficacy and safety of Korean Medicine treatment for traffic accidents during pregnancy. Methods: We investigated the studies on Korean Medicine treatment for traffic accidents during pregnancy via searching through PUBMED, the Cochrane Library, CNKI, and domestic search engines and a total of 6 studies were selected. Results: The major complaints of traffic accidents during pregnancy were low back pain, neck pain and gastrointestinal symptoms. And there were vaginal bleeding and pruritus vulvae in the complaints. All of the studies were given acupuncture treatment for symptom relief, and chuna, herbal acupuncture and cupping were administered. Herbal medicine was also performed, and the most prescribed herbal medicine was Antaeeum-gamibang. All cases reported as traffic accidents during pregnancy showed a reduction in symptoms, normal pregnancy maintenance and delivery, and no miscarriage were reported. Conclusions: Korean Medicine treatment is an effective and safe treatment option for traffic accidents during pregnancy. Further systematic studies are needed to establish the basis for Korean Medicine treatment for traffic accidents during pregnancy.

Seismic demand on nonstructural components (NSCs) is highly dependent on the coupled behavior of a combined supporting structure-NSC system. Because of the inherent complexities of the problem, many of the affecting factors are inevitably neglected or simplified based on engineering judgments in current seismic design codes. However, a systematic analysis of the key affecting factors should establish reasonable seismic design provisions for NSCs. In this study, an idealized 2-DOF model simulating the coupled structure-NSC system was constructed to analyze the parameters that affect the response of NSCs comprehensively. The analyses were conducted to evaluate the effects of structure-NSC mass ratio, structure, and NSC nonlinearities on the peak component acceleration. Also, the appropriateness of component ductility factor (R_p) given by current codes was discussed based on the required ductility capacity of NSCs. It was observed that the responses of NSCs on the coupled system were significantly affected by the mass ratio, resulting in lower accelerations than the floor spectrum-based response, which neglected the interaction effects. Also, the component amplification factor (a_p) in current provisions tended to underestimate the dynamic amplification of NSCs with a mass ratio of less than 15%. The nonlinearity of NSCs decreased the component responses. In some cases, the code-specified R_p caused nonlinear deformation far beyond the ductility capacity of NSCs, and a practically unacceptable level of ductility was required for short-period NSCs to achieve the assigned amount of response reduction.

Background Pain in the postoperative body contouring patient has traditionally been managed with narcotic medication. In an effort to minimize side effects and prevent addiction, plastic surgeons are searching for novel ways to provide adequate analgesia, one of which is nerve blocks. This study was conducted with a meta-analysis that evaluates the efficacy of these blocks for patients who undergo breast surgery. Methods A search of the PubMed/MEDLINE database for articles including the terms "post-operative analgesia" OR "postoperative pain management" AND "in plastic surgery" OR "in cosmetic surgery" OR "in elective surgery" in February 2019 generated five studies on elective breast augmentation and reduction mammoplasty that reported pain scores and quantities of opioids consumed. Independent samples t-tests, one-way analysis of variance, and a random effects model were implemented for evaluation. Results A total of 317 patients were identified as having undergone body contouring of the breast, about half of which received a nerve block. Pain scores on a 1-10 scale and opioid dose-equivalents were calculated. Those who were blocked had an average score of 2.40 compared to 3.64 for those who did not (P<0.001), and required an average of 5.20 less narcotic doses (P<0.001). Pain relief following subpectoral augmentation was best achieved with type-II blocks as opposed to type-I and type-II with serratus plane (P<0.001). Conclusions The opioid epidemic has extended to all surgical specialties. Implementation of a nerve block seems to be an efficacious and cost-effective mechanism to not only help with post-operative pain, but also lower the need for narcotics, especially in subpectoral augmentation.

Objectives: This study aimed to examine the effect of the Oral Health Education Program (OHEP) on the change in the children's brushing behavior and reduction in the dental plaque index (PI) and to identify changes in their parents' perception of oral health. Methods: The OHEP was applied 44 children recruited from two childcare centers. We conducted a self-reported survey of the parents at baseline and evaluated the oral conditions of the children at baseline and after 5 weeks. Their brushing behavior was assessed once a week during the OHEP intervention period and daily at home thereafter. We measured the PI after a 12-week follow-up and performed repeated measures analysis of varience. Results: The average PI score of children significantly decreased at week 5 as compared to the baseline (1.90±0.53, p<0.001), despite a substantial increase in week 12 (2.67±0.08, p<0.001). OHEP was effective in reducing the PI score and modifying their brushing behavior. Conclusions: OHEP effectively modified the brushing the behavior of the children. Therefore, it is necessary to develop and expand a systematic oral health education program to promote self-management of oral health in children.

Objective: Atopic dermatitis (AD) is a chronic, recurrent inflammatory skin disease. Both tralokinumab and dupilumab have been recommended in the European Guideline for the treatment of adult patients with severe AD. In Korea, dupilumab has been approved for patients with moderate to severe AD, and reimbursed for those with severe AD. Since there is no clinical trial directly comparing tralokinumab and dupilumab, we conducted indirect comparison to assess the clinical usefulness in patients with AD. Methods: We selected clinical trials for indirect comparison through a systematic literature review. Individual patient data were available for the tralokinumab clinical trial, and aggregated data were available for the dupilumab clinical trial. Therefore, we employed the Matching-Adjusted Indirect Comparison (MAIC) method. The treatment efficacy was assessed based on whether patients achieved a 75% reduction on the Eczema Area and Severity Index (EASI 75) after drug administration. Results: The difference in the proportion of patients achieving EASI 75 between tralokinumab and dupilumab was 4.7% (95% CI: -7.9 to 17.3). Considering the non-inferiority margin for the EASI 75 achievement rate is -10%, tralokinumab is deemed non-inferior to dupilumab as the lower bound of the CI for the difference in the EASI 75 achievement rate between tralokinumab and dupilumab was within -10%. Conclusion: We conducted a MAIC analysis comparing tralokinumab and dupilumab based on EASI 75 achievement. The findings of this study show that tralokinumab is non-inferior to dupilumab and can be implemented in Korean clinical settings with a therapeutic position comparable to dupilumab.

The study analyzed the body shape perception, weight control attitude, nutrition knowledge, and dietary habits of 529 high school students in Jeju surveyed from January 14-18, 2008 according to students' body shape satisfaction, with the aim of providing basic nutritional education data to aid in appropriate weight control for high school students. The data were analyzed by descriptive analysis, T-test, Chi-square test, ANOVA, and Pearson's correlation coefficients, using the SPSS Win 12.0 program. The body mass index (BMI) of subjects was in the normal range. With regard to weight distribution, 59.4% of subjects showed normal weight and girls were significantly more underweight than boys. More girls considered themselves to be fatter than boys and tended to be increasingly dissatisfied with their body shape. Both boys and girls were more interested in weight control for obesity and were significantly less satisfied with their body shape. Efforts at weight control and reduction had occurred significantly more often for girls than for boys. Dietary attitude scores were significantly higher in girls than boys. BMI positively correlated to weight control concern and nutrition knowledge positively correlated to dietary attitude. BMI negatively correlated to the body shape satisfaction, which in turn negatively correlated to food ingestion disorders. Therefore, it is necessary to develop a systematic nutrition educational program that can induce changes in dietary behavior and increase accurate perception and satisfaction of body shape.

Background: Subway stations have the characteristics of being located underground and are a representative public-use facility used by an unspecified number of people. As concerns about indoor air quality (IAQ) increase, various management measures are being implemented. However, there are few systematic studies and cases of long-term continuous measurement of underground station air quality. Objectives: The purpose of this study is to analyze changes and factors influencing IAQ in subway stations through real-time continuous long-term measurement using IoT-based IAQ sensing equipment, and to evaluate the IAQ improvement effect of a bio-filter system. Methods: The IAQ of a subway station in Seoul was measured using IoT-based sensing equipment. A bio-filter system was installed after collecting the background concentrations for about five months. Based on the data collected over about 21 months, changes in indoor air quality and influencing factors were analyzed and the reduction effect of the bio-filter system was evaluated. Results: As a result of the analysis, PM₁₀, PM_2.5, and CO₂ increased during rush hour according to the change in the number of passengers, and PM₁₀ and PM_2.5 concentrations were high when a PM warning/watch was issued. There was an effect of improving IAQ with the installation of the bio-filter system. The reduction rate of a new-bio-filter system with improved efficiency was higher than that of the existing bio-filter system. Factors affecting PM_2.5 in the subway station were the outdoor PM_2.5, platform PM_2.5, and the number of passengers. Conclusions: The IAQ in a subway station is affected by passengers, ventilation through the air supply and exhaust, and the spread of particulate matter generated by train operation. Based on these results, it is expected that IAQ can be efficiently improved if a bio-filter system with improved efficiency is developed in consideration of the factors affecting IAQ and proper placement.

본 연구에서는 음식점의 남은 음식물의 정의를 설정하고, 남은 음식물 저감화와 남은 음식물 재사용 근절을 위한 방안과 이러한 문제가 제대로 지켜지지 않는 원인에 대하여 관련 분야의 전문가 34인과 영업주 14인을 대상으로 면접조사 및 설문조사를 통해 남은 음식물 관리에 관한 정책적개선 방안을 제안하였다. 전문가들은 수저가 닿지 않았던 음식이라도 제공된 후 남은 음식은 재사용할 수 없다는 데 동의하였다. 즉, 수저가 닿은 김치를 포함한 모든 반찬류와 피클은 한번 제공된 후 버려야 한다. 단, 쌈채소, 고추 등의 야채류는 세척 소독 후 재사용 혹은 가열음식에 재사용하는 경우 허용된다고 응답하였다. 급식관리 전문가와 식품위생 전문가가 제공된 후 손대지 않은 채 남은 김치를 다시 재활용하거나 가열식품의 조리에 이용할 수 없다고 주로 응답한데 반해, 식품접객업 영업자들은 재활용 할 수 있다고 응답하여, 실제 음식점 영업 현장에서 김치류의 재활용 가능성이 높은 것으로 추정된다. 남은 음식 저감화가 이루어 지지 않는 원인과 남은 음식 재사용의 원인으로는 '한국적 식문화'와 '대국민 홍보부족'이 공통적인 원인으로 지적되었다. 또한 전문가들은 이 두 문제를 해결하기 위한 방안으로 '대국민 홍보'와 '소비자 및 영업 주 종사원 교육'을 통한 식생활 개선과 현장 음식문화 개선을 공통적으로 제안하였다. 과거에 음식문화 개선이 영업자 중심으로 이루어졌기 때문에 실제 소비자들의 관심과 협조를 유발하지 못한 점을 고려하면 대국민 홍보는 상당한 효과가 있을 것으로 기대된다. 소비자들이 음식물을 남기면 결국 소비자들에게도 피해가 발생된다는 점을 부각시킴으로써 소량배식 및 좋은 식단제 등을 통한 영업주측의 식문화 개선 정책 시도에 대한 소비자들의 오해와 불만을 완화시키는데 대국민 홍보가 긍정적인 영향을 미칠 것이다. 또한 전문가들은 보다 구체적인 남은 음식물 저감화 방안으로 '반찬선택제'와 '소량배식'을 꼽았으며, 남은 음식물 재사용 근절 방안으로는 '식당 내 남은 음식통 설치 의무화'를 통해 남은 음식이 식당 내로 재진입되는 것을 막을 수 있는 방안을 제안하였다. 이러한 방안들은 영업주와 종사원들의 실천의지를 전제로 식품접객업소 단위에서 적극적으로 적용할 수 있으므로 남은 음식물 관리를 위한 효과적인 방안이라 사료된다. '남은 음식 재사용 여부를 검증하는 과학적 기법 개발'은 남은 음식물의 재사용이 은밀히 이루어져 공개적인 지도와 개선이 어려운 점을 고려할 때 객관성과 과학적 근거를 토대로 한 가장 합리적이고 신속한 방안이다. 음식물에 혼입된 타액 효소의 검출을 위한 키트를 현장에 적용할 수 있다면 남은 음식물 재사용을 근절하는 가장 효과적인 해결책이 될 것으로 기대된다. 본 연구를 통해 제안된 남은 음식물 발생과 재사용 근절 방안들은 현재 한시적으로 운영되고 있는 남은 음식물 관련 정책의 향후 보완에 적용될 수 있을 것이다.
