A number of trend test methods, i.e., Military Handbook test and Laplace test etc., have been applied to investigate recurrent failures trend in repairable systems. Existing methods provide information about only existence of trend in the system. In this paper, we propose a new change-point test based on the Schwarz Information Criterion(SIC). The change-point approach is more informative than other trend test methods in that it provides the number of change-points and the location of change-points if it exists, as well as the existence of change-point for recurrent failures. The change-point test is applied to nine 300MW generating units operated in East China. We confirm that the change-point test has a potential for establishing optimal preventive maintenance policy by detecting change-point of failure rate.

The purpose of this study was to provide basic materials on establishing convergence oriented respiratory infection management system in nursing students attending clinical training by analyzing anxiety, knowledge, possibility of infection, possibility of prevention, and compliance level of preventive behavior. Data were collected from 222 nursing students experienced clinical practice from June 15th to 30th in 2015 using questionnaire. Characteristics relative to variables were measured, and analyzed using SPSS 18.0 program. The results are as follows. The anxiety was 42.70(max 80 points), but possibility of infection was 22.55(max 100 points). Also, knowledge(11.73 out of 16 points), possibility of prevention(7.37 out of 10 points), and compliance level of preventive behavior(34.55 out of maximum 48 points) were slightly above average. The influencing factors on compliance of preventive behavior were anxiety and possibility of prevention. It is needed to lead convergence oriented approach on enhancing compliance of preventive behavior through providing information and educating possibility of prevention during MERS outbreak.

Background : There is increased recognition that rigorous approach to functional assessment will complement the assessment of clinical status. This study is to develop the appropriate visual function index in Korean patients with cataracts by the assessment of the reliability, validity of visual function indexes including VF-14. Methods : An prospective study was performed with 92 patients who had undergone either one eye or both eye cataract surgery by 3 ophthalmologists practicing at a university hospital. Patients were interviewed. and clinical data were obtained. Doctors were questioned with self-entered questionnaire forms. Medical record was examined to understand surgery process. The survey was conducted at 1-2 days before cataract surgery. Results : We used following measures : 7 visual function indexes, global measures of patients' trouble and satisfaction with vision, and best-corrected visual acuity(VA) in each eye. 7 visual function indexes showed a high internal consistency reliability (Cronbach's alpha coefficients ${\geq}$ 0.86). The better visual acuity(operated eye, better eye), the higher patient satisfaction with vision, the lower symptom score, the lower patient trouble with vision was correlated with preoperative visual function index scores. Among 7 indexes, VF-12 with the exclusion of 2 items drivings from VF-14 is a high Cronbach's alpha coefficient and correlation coefficient and the highest $R^2$. Conclusion : We conclude that VF-12 is reliable and valid in Korea. So we suggest that in Korea, all items of VF-14, the visual function index, which is in use internationally, ought to be surveyed and VF-12 which has been excluded by 2 items of drivings from VF-14 ought to be used for analysis.

The concept of precision medicine-prevention and treatment strategies that take individual variability into account-is hot issue of US in the year 2015. Precision medicine is a new concept that approach patients individually by there characteristics, such as genome, life style, environmental exposure, etc. For developing the precision medicine, National Institute of Health of US has been prepared the Precision Medicine Initiative Cohort Program, at least 1 million people cohort. The US President Obama announced the Precision Medicine Initiative on 30th January 2015. He announced that he will pioneer a new model of patient-powered research that promises to accelerate biomedical discoveries and provide clinicians with new tools, knowledge, and therapies to select which treatments will work best for which patients. Most medical treatments have been designed for the 'average patient.' As a result of this 'one-size-fits-all-approach,' treatments can be very successful for some patients but not for others. This is changing with the emergence of precision medicine, an innovative approach to disease prevention and treatment that takes into account individual differences in people's genes, environments, and lifestyles. Precision medicine gives clinicians tools to better understand the complex mechanisms underlying a patient's health, disease, or condition, and to better predict which treatments will be most effective. The healthcare researcher should prepare the new medicine era such as bio-information technology convergence, big data study.

Background: In Korea, the problem of physician workforce imbalances has been a debated issue for a long time. This study aimed to draw key lessons and policy implications to Korea by analyzing projection models of physician demand/supply among five countries. Methods: We adopted theoretical framework and analyzed detail indicators used in projection models of demand/supply comparatively among countries. A systematic literature search was conducted using PubMed and Google Scholar with key search terms and it was complimented with hand searching of grey literature in Korean or English. Results: As a results, Korea has been used a supply-based traditional approach without taking various variables or environmental factors influencing on demand/supply into consideration. The projection models of USA and Netherlands which considered the diversity of variables and political issues is the most closest integrated approach. Based on the consensus of stakeholder, the evolved integrated forecasting approach which best suits our nation is needed to minimize a wasteful debate related to physician demand/supply. Also it is necessary to establish the national level statistics indices and database about physician workforce. In addition, physician workforce planning will be discussed periodically. Conclusion: We expect that this study will pave the way to seek reasonable and developmental strategies of physician workforce planning.

Background: To evaluate the overtreatment rate with the see and treat approach in the management of women with abnormal cervical cytology. Materials and Methods: A retrospective review of patients with abnormal cervical cytology who underwent S&T at MSMC between January 2008 and December 2012 was conducted. Loop electrosurgical excision procedure (LEEP), histological results, cytology and colposcopic impression were analyzed to evaluate overtreatment rate, cyto-histologic correlation and related factors. Results: Average age of S&T cases was 42 years. Ninety seven percents were referred from affiliated health care providers. The study revealed 83.2% patients had HSIL or higher from cervical cytology. Correlation between HSIL and final histology was relatively low at 75% compared to other studies. Overtreatment rate was 28%. Conclusions: S&T was done in 197 patients in a tertiary care health facility with patient satisfaction. Overtreatment occurred, but the rate can be reduced with appropriate recommendations. HSIL Pap smears should be reexamined before S&T while low grade and lesser colposcopic impression groups should obtain conventional colposcopic approach for patient future reproductive benefit.

The New Public Health(NPH) is a comprehensive approach to protecting and promoting the health status of each individual member and society as a whole. NHP is not so much a philosophy to broaden the understanding of public health as it is an action plan to address current public health system. This paper's objectives include increasing public and professional awareness of the significant changes in the national public health systems of developed countries and contributing to more effective delivery of public health services in Korea. This paper reviews articles and documents concerning NPH and the public health system, and outlines of the achievements in developed countries since NPH movement began. These include the change in the definition and function of public health, expansion of public health networks, strengthening of public health policy, reorientation of public health delivery systems, promotion of workforce capacity, and the implementation of evidence-based management. To overcome the challenges facing the public health system of Korea, we must prioritize the value of population-based approach, expand the notion of a public health system to encompass all sectors that can influence health, promote a "Health in All Policies" approach, focus on an evidence-based health policy and program, develop core competencies for public health workers, and establish performance standards for public health organizations based on the core functions of public health.

Yemen has been faced with the worst cholera epidemic of modern times, with more than 1 million suspected cases and 3000 deaths at the time of writing. This problem is largely due to the longstanding civil war between pro-government forces and the Houthi armed movement, which has severely damaged already vulnerable sanitation and healthcare facilities and systems in the country. It is further compounded by a dire lack of basic amenities, chronic malnutrition, and unfavourable weather conditions. Another contributory component may be aerial transfer by cholera-infected chironomid insects. To contain the spread of cholera in Yemen, a nation-wide armistice should be negotiated, and national and local committees must be convened to coordinate efforts on the ground. Community isolation facilities with proper sanitation, reliable disposal systems, and a clean water supply should be set up to isolate and treat sick patients. The continuity of vaccination programmes should be ensured. Public health campaigns to educate local communities about good hygiene practices and nutrition are also necessary. The One Health paradigm emphasizes a multi-sectoral and transdisciplinary understanding and approach to prevent and mitigate the threat of communicable diseases. This paradigm is highly applicable to the ongoing cholera crisis in Yemen, as it demands a holistic and whole-of-society approach at the local, regional, and national levels. The key stakeholders and warring parties in Yemen must work towards a lasting ceasefire during these trying times, especially given the extra burden from the mounting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak worldwide.

Environmental medicine has interest in the effect of natural environment on the human health. Nature is usually understoodas' sky(天)' and 'earth(地)' which implies the harmony of humankind and nature(天地相應). As can be shown above, environment concept is the basic in Korean Medicine which originate in "Huangdi's Internal Classic" as clear medical form. According to "Huangdi's Internal Classic" man ought to abide by the nurturing 'Tao(道)' which is the way of life. This can be explained as the principle of balance, specially of yin(陰) and yang(陽) as is represented by the transformation of the energies from the universe. Life through the four seasons is also referred in the classic upon when four different climates have some effect on people, and the regional effect on health is also written there. Under the strict modem view, the achievement of the classic in the field of environmental medicine may be treated as primitive, but it was induced through long-term observation, so that once was state-of-the-art result at that time. But to solve the intrinsic weak points in traditional environmental medicine and also to harmonize with modern science to contribute to national health, the way of modem research can be applied to traditional concept on environmental medicine. Natural scientific approach is to avoid superstition and incantation. Strict method approach is to enhance accuracy and reliance in clinical observation. Overall, predictability can help develop the effectiveness and efficiency of diagnosis, treatment, recurrence, and prevention in environmental disease with holy method of Korean Medicine.
