Objectives: To investigate the association between psychological distress and obesity among law enforcement officers (LEOs) in the United States. Methods: Self-reported data on psychological distress based on six key questions were obtained from LEOs who participated in the National Health Interview Survey (2004-2010). We used Prochaska's cut-point of a Kessler 6 score ${\geq}5$ for moderate/high mental distress in our analysis. Mean levels of body mass index (BMI) were compared across three levels of psychological distress. Results: The average age of LEOs (n = 929) was 39.3 years; 25% were female. Overall, 8.1% of LEOs had moderate or high psychological distress; 37.5% were obese (BMI ${\geq}30$). Mean BMI increased with increasing psychological distress (no distress, BMI = $27.2kg/m^2$; mild distress, $27.6kg/m^2$; and moderate/high distress, $33.1kg/m^2$; p = 0.016) after adjustment for age, race, income, and education level among female officers only. Physical activity modified the association between psychological distress and BMI but only among male LEOs (interaction p = 0.002). Among male LEOs reporting low physical activity, psychological distress was positively associated with BMI ($30.3kg/m^2$ for no distress, 30.7 for mild distress, 31.8 for moderate/high distress; p = 0.179) after adjustment, but not significantly. This association was not significant among males reporting high physical activity. Conclusion: Mean BMI significantly increased as psychological distress increased among female LEOs. A longitudinal study design may reveal the directionality of this association as well as the potential role that physical activity might play in this association.

현 도로교통법상 도로 이용의 효율성과 교통안전 확보의 목적으로 차로 별 통행 가능 차종을 지정한 제도로써, 2020년 개정안이 현재 시행되고 있다. 독일과 국내의 자동차 1만 대당 교통사고 사망자 수를 비교하였을 때, 독일의 교통사고 사망자는 국내보다 현저히 낮은 수치를 기록하고 있다. 대표적으로 속도의 제한을 두지 않은 독일 아우토반의 사례는 한국의 속도위반법만이 사고율의 경감에 정답이 되지 않는다는 점을 시사한다. 아우토반 고속도로의 킵 라이트 원칙(keep right principle)에 따라 준수되는 지정차로제는 교통사고 감소에 큰 역할을 한다. 이러한 사실을 기반으로 지정차로제 위반 차량의 단속과 준수율 향상을 위한 교통 단속 시스템을 제안한다. 딥러닝 객체 인식 모델인 Yolo5를 이용하여 차종을 인식하고 OpenCV를 이용하여 차량 번호판과 차선을 인식 및 추출된 데이터를 서버에 저장하여 법규의 위반 여부를 판별하는 지정차로제 단속시스템을 개발한다. 이에 따라 운전자의 제도 인식 및 준수율의 향상을 통한 교통사고율의 감소 효과가 있을 것으로 기대된다.

현행 액화석유가스의 안전관리 및 사업법의 시행규칙에 의거하면 액화 가스는 용기 체적의 85%까지 충전하도록 되어있다. 이에 상당하는 충전량은 $65^{\circ}C$를 기준으로 내부에 액체의 열팽창을 고려한 수치이다. 하지만 소형 또는 이동이 용이한 용기가 특정 상황에서는 용기 내부 액체의 온도가 $65^{\circ}C$ 미만을 유지한다고 단정 지을 수 없다. 열역학적 관점에서 액 팽창은 용기 재료의 강성만으로 제어하기 어려운 요소이며, 결국 파열 등의 사고를 유발 할 수 있는 잠재적인 위험 요인이 된다. 따라서 본 논문에서는 밀폐계에서 임계상태 액체 프로판의 열 팽창량을 추정하는 방법과 추정 된 결과를 제시 할 것이며, 내압 변화에 따른 용기의 체적 증가를 유도하는 구조적 요소를 실험적으로 제안할 것이다. 본 논문을 통해 제시된 결과는 향후 액화가스의 압력용기 설계에 있어 중요한 기초 자료가 될 것으로 사료된다.

Purpose: Korea, China, and Japan can be seen as a geopolitical community that has developed through various relationships in terms of history. However, nowadays, it seems that they are pursuing different societal goals resulting from the difference in political and social systems, demographic structures, and economic situations. The law provides the minimum standards for people's lives in the direction that the society pursues. Therefore, the aim of this study is to examine the architectural differences in medical facilities and their causes comparing the legal standards of medical facilities in Korea, China, and Japan. Methods: The subject of the study is Korea, China, and Japan's legal standards of facilities corresponding to the Korean medical service act; enforcement decree of medical service act; and enforcement rules of medical service act. The scope of the study is as follows: First, the facilities standards and the reason for the revision of the standards after the 1950s when the current system of each country was established are investigated and thus the changing trends of the facilities standards that each country has pursued are analyzed. Second, the range and level presented by the current facilities standards of each country are compared and the differences are analyzed. Finally, cases in which the differences in the legal facilities standards are reflected in the actual design are compared and the effect of the facilities standards of medical facilities on the architectural plan is identified. Results & Implications: Each country differs in the legal standards of facilities because of changes in demographic structure and experience of disease. Moreover, it is identified that differences in social operating systems, especially in the operating methods of medical facilities, affect the range and level enforced by the facility standards. When investigating and researching foreign standards of facilities and cases for foreign medical facilities, it is required that they should be analyzed in consideration of the social and cultural aspects of each country.
