This research conducted an the failure analysis was performed based on the failure and operation data for Seven years using the Reliability, Availability, Maintainability, and Safety(RAMS) constructed at the operation stage after the opening of the D urban railway. therefore, the risk priority was selected for failure frequency component within the door system that showed high failure. Finally, the goal was to suggest ways to improve the door system. For this purpose, the analysis of thermal characteristics of failed components such as Door Control Unit(DCU) in the door system based on the Seven-year failure analysis data of RAMS was performed. These results were applied to the main component exchange cycle of the door unit, the mean time between failure(MTBF) and mean kilometer between failure(MKBF) values of RAMS increased by 26% in 2017-2018 when the improvement measures were taken, and the MTBF value of DCU was 300,000 hours, which was a 57% improvement in reliability. The results of this thesis identify potential enhancements in reliability and improvements in maintenance of the door system that, if implemented, would contribute to train safety and reduce instances of failure in the future.

Increasing occupational cerebrovascular & cardiovascular disease, it becomes the most serious problem in the occupational health management. Hypertension is the most important risk factor of cerebrovascular & cardiovascular disease. Although treatment for hypertension has the priority, hypertension has not been managed systematically at the worksite. The objectives of this study were to investigate the actual situation of its treatment, figure out what factors can affect compliance for hypertension treatment and analyze the relations between compliance and employment status. Subjects were 28 workers who have been diagnosed as hypertension at periodic health examination, 20 workers who have been managed for hypertension at dispensary and 22 workers who were diagnosed during the study periods. The results of the study were as follows; 1. More women have been hired as part time workers and had lower education background and income than the full time workers. 2. Among the factors that have been known to affect the treatment compliance, part time workers had less supports from the company than full time workers. 3. We got the comparison of difference between compliance and variables that the factor grade of cure promotion and average ages are high in high compliance. In conclusion there were not the difference of compliance by employment status. But it was hard to rule out the selection vias because the sample size was so small. So it seems difficult to generalized the conclusion that employment status doesn't affect the treatment compliance.

The objective of this paper is to present relevant information and data from domestic and foreign references and to propose legal standards on pesticide residues in order to mitigate the pesticide contamination in the water environment. Among 200 pesticide ingredients in use in Korea, items necessary for standard setting were selected and theoretical residue limits were computed. The results are summarized as follows. In advanced countries, drinking water standards are established on the basis of health index ADI and water intake, whereas standards for surface water are established temporarily on the basis of different parameters, inconsistent with different countries. Pesticide residue limits applicable in Korea were proposed for 24 pesticides in drinking water(health basis) and for 25 pesticides in surface water(ecotoxicological basis), as selected by risk priority. It was recommended to accumulate scientific data by persistent research efforts in order to maintain the justification of the pesticide residue limits in water and relevant research topics to be undertaken in future were proposed.

Tobacco use is the most important preventable risk factor for premature death. The World Health Organization (WHO) Framework Convention on Tobacco Control (FCTC), the first international public health treaty, came into force in 2005. This paper reviews the present status of tobacco control policies in Korea according to the WHO FCTC recommendations. In Korea, cigarette use is high among adult males (48.2% in 2010), and cigarette prices are the lowest among the Organization for Economic Cooperation and Development countries with no tax increases since 2004. Smoke-free policies have shown incremental progress since 1995, but smoking is still permitted in many indoor public places. More than 30% of non-smoking adults and adolescents are exposed to second-hand smoke. Public education on the harmful effects of tobacco is currently insufficient and the current policies have not been adequately evaluated. There is no comprehensive ban on tobacco advertising, promotion, or sponsorship in Korea. Cigarette packages have text health warnings on only 30% of the main packaging area, and misleading terms such as "mild" and "light" are permitted. There are nationwide smoking cessation clinics and a Quitline service, but cessation services are not covered by public insurance schemes and there are no national treatment guidelines. The sale of tobacco to minors is prohibited by law, but is poorly enforced. The socioeconomic inequality of smoking prevalence has widened, although the government considers inequality reduction to be a national goal. The tobacco control policies in Korea have faltered recently and priority should be given to the development of comprehensive tobacco control policies.

Subcontractors have an increased risk of accidents compared to large contractors. Subcontractors' safety management system is in close association with workers in construction sites. Contractors should strengthen subcontractors' roll and responsibility and provide continual support to prevent an accident. And also these supporting system should be provided to subcontractors' headquarters as well as construction site. Contractors' priority management for subcontractors safety should be transferred from the post management for disciplinary action to the preventive management to improve subcontractors participation and safety performance. Subcontractors can not establish the safety management system with just a one time supporting only. Contractors support and monitoring should be provided to subcontractors regularly and continuously to establish their self safety management system. The subcontractors safety management system improvement program(SSMSIP) suggested in this study will be a effective supporting system for subcontractors to establish and improve their safety management system. If we carry out the objective and quantitative evaluations and supporting system such as SSMSIP and provide the consequential incentive program to subcontractors, it can contribute to the accident reduction.

The absolute necessity of cancer registration for cancer control planning is well accepted. The registry at the national or local level can provide not only essential data for cancer incidence, mortality and survival but may also point to risk and protective factors and efficacy of interventions by conducting epidemiological research. Timely publication of research findings in PubMed indexed journals is of the essence, especially in examples that allow free access so that the widest dissemination of information can be achieved. The present commentary covers the scope of research in Asia or using Asian data the period 2008-2013, nearly 40% of a total of over 300 papers being published in the APJCP. In order to reach its full potential the registry should incorporate many skills. Cooperation for this purpose, whether it be national, regional, Asia-wide or international, is a high priority and the International Agency for Research on Cancer, together with the National Cancer Institute in Thailand and the APOCP/APJCP are staging an Asian Cancer Network Forum in Bangkok in February of 2014 to allow discussion of ways forward. It is hoped that representatives from all regions of Asia will decide to attend and a l so contribute country reports for publication in a special supplement of the APJCP.

Breast cancer is the most common malignancy in women around the world. Information on the incidence and mortality of breast cancer is essential for planning health measures. This study aimed to investigate the incidence and mortality of breast cancer in the world using age-specific incidence and mortality rates for the year 2012 acquired from the global cancer project (GLOBOCAN 2012) as well as data about incidence and mortality of the cancer based on national reports. It was estimated that 1,671,149 new cases of breast cancer were identified and 521,907 cases of deaths due to breast cancer occurred in the world in 2012. According to GLOBOCAN, it is the most common cancer in women, accounting for 25.1% of all cancers. Breast cancer incidence in developed countries is higher, while relative mortality is greatest in less developed countries. Education of women is suggested in all countries for early detection and treatment. Plans for the control and prevention of this cancer must be a high priority for health policy makers; also, it is necessary to increase awareness of risk factors and early detection in less developed countries.

Background: Older age is associated with an increase in the incidence of cancer cases. Diagnosis and treatment of cancer in older adults can be stressful because of health decline related to age, comorbidities and inadequate treatment for pain and other symptoms of the disease. This survey is one of the unique studies in Jordan and in the Arab world that aimed at exploring the predictors of older adult individuals awareness towards cancer. Materials and Methods: A stratified random sampling technique was followed to reach a representative sample of 753 participants. The questionnaire of the study consisted of parts regarding demographic variables, awareness about screening tests, and signs and symptoms of cancer. In addition, specific questions related to factors linked to cancer were included. Cross-sectional design was adopted with face-to-face interviews at the interviewees' households. Results: The mean age of the participants was about 63 years; around 44% of them are above the age of 65 years. 'Being convinced that having no health problem makes the individual feel safe and not at risk of getting cancer' was the major reason for not doing a routine health check-up. Conclusions: The low levels of awareness about cancer, as well as the low use of the screening methods were crucial outcomes of this study. Thus, raising the awareness among health care providers and policy makers in the country about older adults' perception of cancer is a high priority.
