Physical inactivity has reached epidemic levels in developed countries and is being recognized as a serious public health problem. Recent evidence shows a high percentages of individuals worldwide who are physically inactive, i.e. do not achieve the WHO's present recommendation of 150 minutes of moderate to vigorous intensity per week in addition to usual activities. Living in sedentary lifestyle is one of the leading causes of deaths and a high risk factor for several chronic diseases, like cancer, cardiovascular disease, diabetes type 2, and osteoporosis. This article summarizes evidence for relative risk of the civilization diseases attributable to physical inactivity and the most important conclusions available from the recent investigations computing the economic costs specific to physical inactivity. The findings provide health and economic arguments needed for people to understand the meaning of a sedentary lifestyle. This may be also useful for public health policy in the creation of programmes for prevention of physical inactivity.

The purposes of this study were to explore the perceived risk of smart clothing, to classify consumers by risk perception of smart clothing, and to investigate the differences among the segmented groups in regard to the evaluation of newness and innovativeness of smart clothing. In addition, the relationship among perceived risk, evaluation of newness and innovativeness of smart clothing were examined. A questionnaire was administered to 338 male and female subjects aged from 17 to 50. Analysis was performed by factor analysis, cluster analysis, ANOVA, and Pearson's correlation analysis. The results showed that the perceived risk of smart clothing was composed of 4 factors: economic risk, social risk, functional risk and physical risk. Consumers were classified into four groups: high risk perception group, low economic risk perception group, low functional risk perception group, and low social risk perception group. ANOVA showed that there were significant differences among four groups regard to the evaluation of newness and innovativeness of smart clothing. High risk perception group most highly evaluated the newness and innovativeness of smart clothing. There were positive correlation among the perceived risks, the evaluation of the newness and innovativeness of smart clothing.

In this paper, we report computational testing result to examine the validity of firm's bankruptcy risk estimation through quantification of supply chain risk. Supply chain risk in this study refers to upstream supply risk and downstream demand risk, To assess the firm's risk affected by supply chain risk, we adopt unit of analysis as industry level. since supply and demand relationships of the firm could be generalized by the industry input-output table and the availability of various valid economic indicators which are chronologically calculated. The research model to estimate firm's risk level is the linear regression model to assess the industry bankruptcy risk estimation of the focal firm's industry with the independent variables which could quantitatively reflect demand and supply risk of the industry. The publicly announced macro economic indicators are selected as the candidate independent variables and validated through empirical testing. To validate our approach, in this paper, we confined our research scope to steel industry sector and its related industry sectors, and implemented the research model. The empirical testing results provide useful insights to further refine the research model as the valid forecasting mechanism to capture firm's future risk estimation more accurately by adopting supply chain industry risk aspect, in conjunction with firm's financial and other managerial factors.

과학기술의 발달에 힘입어 자연현상에 대한 인간의 조절능력은 획기적인 발전을 거듭하고 있다. 그럼에도 불구하고 최근 수십년간 자연재해와 관련된 비용이 세계적으로 증가하고 있는데, 이는 새로운 형태의 대규모 자연재해가 급증하고 있기 때문이다. 이러한 경향은 여러 가지 측면에서 나라나고 있으며, 향후 더 큰 규모의 재앙이 더욱 빈번하게 나타날 가능성도 감지되고 있다. 특히, 특정 재해의 위험성에 대하여 올바르게 인지하지 못하는 현상은 재해에 대한 위험성을 전이시키고 장기적으로는 재해에 대한 사회적 취약성을 확대시킬 수 있는 여지를 가지고 있다. 따라서 재해에 대한 올바른 인지와 이에 대한 효과적인 적응양식을 지역의 사회 경제적 구조와 연결지어 분석하는 작업은 환경재해로 일컬어지는 인위적 재해의 발생을 줄일 수 있는 중요한 작업이다.

In Korea, no CRA (comparative risk analysis) studies have been undertaken, nor have their methodologies of such studies been established. Therefore, the objectives of this study were to establish the framework of CRA consisting of health risk, economic risk and perceived risk, and to estimate and compare these risks among the three environmental problems of air pollution, indoor air pollution and drinking water contamination, which are themselves subject to the eight sub -problems of hazardous air pollutants (HAPs), regulated pollutants (representative as PM 10) and dioxins (PCDDs/PCDFs) in air pollution, indoor air pollutants (IAPs) and radon in indoor air pollution, and drinking water pollutants (DWPs), disinfection by -products (DBPs) and radionuclides in drinking water contamination in Seoul, Korea. After which, the priorities of these problems were set by individual and integrated risk. From the results, the rankings of both health risk and economical risk were in the following order: radon, PM10, IAPs, HAPs, DWPs, dioxins, DBPs, and radionuclides among the eight sub problems. On the contrary, the ranking of perceived risk was in the following order: HAPs, dioxins, radionuclides, PM10, DWPs, IAPs, Radon and then DBPs among the eight sub-problems.

본 연구의 목적은 캄보디아와 베트남의 국가위험도와 영향요인들을 비교 분석하는 것이다. OECD와 한국수출입은행 모두 베트남보다는 캄보디아의 국가위험도를 더 높게 평가하고 있다. 국가위험도 분류에 따른 각각의 평가요소들에 대해 모수검정을 실시한 결과, 정치 사회적 위험 지표인 부패지수, 경제적 위험 중 국내경제 지표인 경제성장률, 경제적 위험 지표 중 대외거래 지표들, 경제적 위험 중 외채 관련 지표가 두 국가 간의 국가위험도 차이에 통계적으로 유의한 영향을 미쳤다. 국가위험도 분류에 따른 평가요소별 모수검정 결과를 토대로 판별요인 분석을 통해 두 국가 간의 국가위험도를 가장 잘 나타내는 요인들을 추가로 추정한 결과, 정치 사회적 위험 지표인 부패지수, 경제적 위험 중 국내경제 지표인 경제성장률, 경제적 위험 중 외채 관련 지표인 외환보유액/월평균수입이 캄보디아와 베트남 간의 국가위험도 차이를 잘 대변하는 것으로 나타났다. 결론적으로 캄보디아가 국가위험도를 베트남 수준으로 낮추기 위해서는 무엇보다도 부패척결, 수출증대 등 대외거래 확대가 필요하다고 할 것이다. 베트남 또한 지속적인 경제성장 달성과 외환보유고 증대에 주력할 필요가 있을 것이다.

Background: This study used Surveillance, Epidemiology and End Results (SEER) pancreatic cancer data to identify predictive models and potential socio-economic disparities in pancreatic cancer outcome. Materials and Methods: For risk modeling, Kaplan Meier method was used for cause specific survival analysis. The Kolmogorov-Smirnov's test was used to compare survival curves. The Cox proportional hazard method was applied for multivariate analysis. The area under the ROC curve was computed for predictors of absolute risk of death, optimized to improve efficiency. Results: This study included 58,747 patients. The mean follow up time (S.D.) was 7.6 (10.6) months. SEER stage and grade were strongly predictive univariates. Sex, race, and three socio-economic factors (county level family income, rural-urban residence status, and county level education attainment) were independent multivariate predictors. Racial and socio-economic factors were associated with about 2% difference in absolute cause specific survival. Conclusions: This study s found significant effects of socio-economic factors on pancreas cancer outcome. These data may generate hypotheses for trials to eliminate these outcome disparities.

The benefits of pesticides in improving the food quantity and quality requirements for an increasing world population are significant, and they can be described in agronomic, economic and social terms. The risks are assessed from the hazards which are likely to occur in practice ; the hazards are defined by the toxicity of the pesticide to non-target organisms at various exposure levels. There are ways of reducing the risks (mainly by reducing exposure in practice) and improving the benefits of pesticides ; these are known as risk management and benefit management respectively. The overall risk-benefit assessment is facilitated if each component can be expressed in financial terms, but it must be made nationally or locally on a sound technical basis against the prevailing agronomic, socio-economic and political circumstances. Paraquat is used to illustrate the risk-benefit assessment process in general terms, and the conclusion is that the benefits greatly outweigh the risks. It is important to keep the risks of pesticides in perspective with those associated with other naturally occurring chemicals in our diet and with other everyday aspects of life. In an overall context, the pesticide risk is small.
