PURPOSES : This study estimated the load effect of a single heavy truck to develop a live load model for the design and assessment of bridges located on an expressway with a limited truck entry weight. METHODS : The statistical estimation methods for the live load effect acting on a bridge by a heavy vehicle are reviewed, and applications using the actual measurement data for trucks traveling on an expressway are presented. The weight estimation of a single vehicle and its effect on a bridge are fundamental elements in the construction of a live load model. Two statistical estimation methods for the application of extrapolation in a probabilistic study and an additional estimation method that adopts the extreme value theory are reviewed. RESULTS : The proposed methods are applied to the traffic data measured on an expressway. All of the estimation methods yield similar results using the data measured when the weight limit has been relatively well observed because of the rigid enforcement of the weight regulation. On the other hand, when the estimations are made using overweight traffic data, the resulting values differ with the estimation method. CONCLUSIONS : The estimation methods based on the extreme distribution theory and the modified procedure presented in this paper can yield reasonable values for the maximum weight of a single truck, which can be applied in both the design and evaluation of a bridge on an expressway.

In Korea, Abortion in the Criminal Law is an illegal act in exception of on which abortion may be carried out through the grounds are very limited and related such a emergency situation of women's physical health, rape, incest and genetic diseases. The Criminal Law regulates the mother's act of abortion and the doctor's surgical performance of abortion. The Mother and the Child Health Law prescribes the medical, ethical, and genetic grounds for the legal permission of abortion. Many people tend to abuse of abortion even though they are fully aware of its illegality. The law lead to be inconsistent with its enforcement. In this paper, I would like to suggest some proposals about the legal analysis of the Abortion Regulations th reform the existing regulation and increase th effectiveness of the regulations. Recently, in a case of the a maternity hospital where a midwife left alone a diabetes pregnancy women who had a baby, and the overweight baby(5.2Kg) died in the uterus due to hypoxic states. Supreme Court of Korea 2007.6.29. 2005do3832) had given a verdict of "not guilty". It looked like there were very fair with current crime law. But, we want this case to be investigated if there weren't any logical contradictions as well as concurrent translation within Constitution Law. Now the Mother and the Child Health Law prescribes the medical, ethical, and genetic grounds for the legal permission of abortion. But this law does not include social and economic grounds.

Background: Healthcare settings have been recognized among the most hazardous places to work. Based on the five categories of occupational hazards that were identified by the ILO and WHO, this study aimed to analyze policy framework relevant to occupational health protection of health workers (HWs) in public health service in China, then discussed how to share the experience of the National Health Service (NHS) England for improvement. Methods: Based on policy learning theories, policy analysis and qualitative interview were used in this study. Results: In the Chinese public health service, at least five laws related to the regulation of occupational health protection for HWs; however, enforcement of relevant laws was separated and multi-centered; the national monitoring system, which targeted to occupational hazards and health outcome for HWs in China, had yet to be developed; the top three priorities were workplace violence, bloodborne pathogens, and musculoskeletal disorders; national strategies included Security Hospital, and Healthy China 2030. In NHS England, three laws were fundamental; several monitoring systems had been set up, including NHS Staff Survey, Commissioning for Quality and Innovation incentive scheme; mental health, musculoskeletal problem, and nutrition disorder and overweight were raised great concern; Health and Safety, and NHS Healthy Workforce Program were critical nationwide strategies. Conclusion: There were several similarities as well as differences between the Chinese public health system and NHS England, which laid foundation of learning by China. Recommendations of improving occupational health policies in China were provided, based on the lessons learned from the NHS England.

현행 국내 교량 설계기준의 활하중 모형인 KL-510의 하중 효과를 실측된 통행자료로부터 통계적으로 추정한 트럭의 연행효과 및 국내외 관련 설계기준이 하중모형과 비교한다. 과적단속 전후에 고속도로에서 측정된 트럭의 중량 자료를 이용하여 설계기준의 활하중 모형 결정과 동일한 과정을 따라서 트럭 중량을 산정하여 그 하중효과를 KL-510과 비교하였다. KL-510은 운행제한중량을 초과하는 트럭을 일부 포함하는 자료로부터 추정한 트럭의 연행에 의한 하중효과와 매우 부합하는 결과를 보였다. KL-510은 미국 AASHTO LRFD의 활하중 모형과 일관성 있는 결과를 주며, 기존 하중 모형인 DB-24보다 하중효과의 비율이 균일하였다. 이 연구의 결과로 가상의 하중 모형인 KL-510에 해당하는 실제 트럭의 조합을 구성하였으며, 향후 공용중인 교량의 평가와 허가차량의 하중계수 보정에 적용할 수 있다.
