Background: The objective of this study was to assess the readability, suitability, and health content of cancer screening information in municipal newspapers in Japan. Materials and Methods: Suitability Assessment of Materials (SAM) and the framework of Health Belief Model (HBM) were used for assessment of municipal newspapers that were published in central Tokyo (23 wards) from January to December 2013. Results: The mean domain SAM scores of content, literacy demand, and layout/typography were considered superior. The SAM scores of interaction with readers, an indication of the models of desirable actions, and elaboration to enhance readers' self-efficacy were low. According to the HBM coding, messages of medical/clinical severity, of social severity, of social benefits, and of barriers of fear were scarce. Conclusions: The articles were generally well written and suitable. However, learning stimulation/motivation was scarce and the HBM constructs were not fully addressed. Practice implications: Articles can be improved to motivate readers to obtain cancer screening by increasing interaction with readers, introducing models of desirable actions and devices to raise readers' self-efficacy, and providing statements of perceived barriers of fear for pain and time constraints, perceived severity, and social benefits and losses.

This paper proposes a method to utilize an energy storage system (ESS) based on the assessment of an area of severity (AOS) to voltage sag. The AOS is defined as a set of the fault positions that can cause voltage sags at many buses simultaneously. The assessment of AOS helps to determine an optimal location of ESS installation to minimize the expected sag frequency (ESF) at concerned buses. The ESS has the ability not only to play traditionally known roles but also to mitigate voltage sag impact on renewable energy sources (RES) in the islanded microgrid. Accordingly, using the proposed method the ESS has additional features to prevent the operation failure of RESs and improve the stability of the microgrid. In order to verify the presented method, a case study was conducted on the sample microgrid system that is modified from an IEEE 57-bus system.

Background: The emergence of new infectious diseases threatens public health, increasing socioeconomic damage, and national risks. This study aimed to develop an evidence-based risk assessment tool to quickly respond to new infectious diseases. Methods: The risk elements were extracted by reviewing the risk assessment methods of the World Health Organization, United States, Europe, United Kingdom, and Germany, and the validity and priority of elements were determined through expert meetings and Delphi surveys. Then, the scale and level for each risk element were defined and a final score calculation method according to the risk evaluation result was derived. The developed risk assessment tool was verified using data at the time of domestic transmission of an emerging infectious disease. Results: In case of spread of actual infectious diseases, priority is determined based on the criticality of the elements in each area of transmissibility and severity, from which the weighted score of the risk assessment is derived. Then, the risk score for each element was calculated by multiplying the average value of the risk evaluation by its weight and the evaluation risk assessment score for the two areas was calculated. At last, the final score is plotted in a matrix where the x-axis indicates the transmissibility and the y-axis the severity and plotted on the coordinate plane for time series use. Conclusion: With respect to transmissibility and severity, this risk assessment method to respond to new and re-emerging infectious diseases enables rapid and evidence-based evaluation by quantitatively and qualitatively assessing various risk elements.

Purpose: Assessment of the trauma severity associated with the prognosis of trauma patients. But we are having a lot of difficulties in assess the severity because of scarcity of current first-aid records resources. Methods: We presumed that Applying the Revised trauma score which consist of vital signs and GCS score will be helpful to assess the sevirity.This study covers the 10069 patient of Ewah womans hospital (2011.1.1.-2014.12.31) who are able to verify the GCS score from fist-aid records. Results: There is no distinctions between prehospital RTS and hospital RTS. And shows high level of correlation between prehospital RTS and ISS. Conclusion: Therefore we conclude that checking the GCS and RTS at prehospital state will be help to assess the severity of trauma patients.

This quantitative study was investigated to examine the relationship between severity of state-trait anxiety and disordered eating patterns in some university students. This study used a cross-sectional study design. Total 347 students participated in this study (88 male and 259 female) among three universities. The assessment of eating disorder was conducted by Eating Attitudes Test (EAT-26), a score of >or=20 identified individuals likely to have an eating disorder, including anorexia nervosa and bulimia nervosa. Scores of healthy dietary behaviors were obtained by self-assessment instrument on healthy diet scale(20-item questionnaire), and severity of state-trait anxiety was calculated by state-trait anxiety inventory(Total 40- item questionnaire). In groups for each state anxiety and trait anxiety, there were divided between 50 percentile point of cumulatived scores of state anxiety and trait anxiety in all subjects. Linear regression analysis showed overall significant difference between dietary patterns(anorexia nervosa and healthy dietary behaviors) and severity of state-trait anxiety in all sex. Our results indicated that severity of state-trait anxiety may marked eating disorder symptomatology on dimensions of eating disorder prevention.

Objectives: To evaluate the performance of models to predict AMI patients death using severity adjustment measures in Korea. Methods: Medical records of 861 patients treated by AMI in 7 general hospitals during 1996 and 1997 were reviewed by trained nurses. We measured the severity of patients by APACHE III, MedisGroups, CSI and DS. Using each severity method a predictive mortality for each patient was calculated from a logistic regression model including the severity score. The statistical performance of each severity method model was evaluated by using c-statistics and R2. For each hospital, z scores compared actual and expected mortality rates. Results: The overall in-hospital mortality was 14.5%, ranged from 10.0% to 22.2%. The distributions of severity scores for each method was significantly different by hospitals. The four severity-adjusted models to predict AMI patients death varied in their statistical performance for discrimination power of patients death. Order of Severity-adjusted mortality rates and z scores by four severity measures was different. Conclusion: Severity-adjusted mortality rates of AMI patients might be applied as an indicator for hospital performance evaluation in Korea. Because different severity methods frequently produce different impressions about relative hospital performance, more studies has to be done to use it as quality indicator and more attention should be paid to select appropriate severity measures.

This paper presents a fast method to identify an area of severity which is a network area leading to voltage sags at multiple sensitive load points, simultaneously. To assess voltage sag performance considering various sensitive loads, it is need to determine an area of severity for the load points. The area of severity can be calculated by overlapping areas of vulnerability for each sensitive load. However, as the number of sensitive loads increases, computational complexity and time for determining an area of severity are highly increased. In this paper, an efficient scheme based on line division is described. The proposed method is useful for identifying an area of severity and assessing voltage sag performance considering multiple loads together.

본 논문에서는 해상 구조물들의 화재시 안전성 평가에 대한 연구의 일환으로써 기본적인 구조강도 부재들의 화재시 거동 및 파괴확률을 구해 보았다. 화재에서의 안전성 평가는 부재의 Fire resistance와 화염에 의한 열하중인 Fire severity를 비교하여 이루어질 수 있다고 가정하였다. Fire severity는 육상 건축물에 대한 화재안전 규정인 Eurocode 1의 표준화염 온도변화 곡선과 부재로의 열전달 방정식을 사용하여 부재의 최대온도를 구하게 되며, Fire resistance는 단순 부재의 경우, 간략식과 코드의 활용으로 해결할 수 있지만, FPSO 와 해상 구조물의 복잡성을 고려하여 상용 구조해석 프로그램의 활용을 통하여 탄소성해석 및 대변형등을 고려한 보다 실용적인 부재의 구조강도를 해석하여 주어진 파괴모드에 대한 한계 온도를 구하여 최대온도와 비교하였다. 더불어, Fire resistance 측면에서의 두 접근방식의 비교를 통해서 두 방식의 등가적 성향을 확인하였다. 여기서 Strength, Serviceability, Stability의 세 가지 측면에서 First Hinge, Large Deflection, Buckling의 세 가지 파괴모드를 상정하고 각각에 대한 파괴여부를 확인하였고, 이렇게 구해지는 Fire severity와 Fire resistance의 식에 AFOSM 방법을 적용하여 최종적으로 부재의 파괴확률을 구하는 방식을 통해, 단순 부재인 Beam 및 Plate 예제에 적용하여 구조물의 화재시 거동 및 각 파괴모드에 대한 파괴여부를 구하였다.
