  • The principle and methodology of risk assessment was applied to establish the quality standard of potential impurities of drinking water treatment chemicals. The impurities(arsenic, lead, cadmium, chromium, mercury, etc.) are regulated as the contained quantity of chemicals in Korea while they are regulated as the quality standard with the idea of 10% of the national safety drinking water standard in U.S.A(NSF) and Japan(JWWA). According to risk assessment of the current standard implemented in Korea, the excess cancer risk of arsenic and lead were determined in around $10^{-5}$ and the hazard quotient(HQ) of cadmium and chromium were below $10^{-2}$, respectively. And the standard concentration of the impurities are regulated as much as 2%~6% of the national drinking water quality standard. The values are more enforced rather than the standards in U.S.A(NSF) and Japan(JWWA) regulating the concentration of impurities the 10% of the national drinking water quality standard. We conclude that the impurities standard of drinking water treatment chemicals should be reconsidered comprehensively concerning the national safety drinking water quality standard and risk assessment.

  • The Green Building Certification is issued through self-assessment of applicant, assessment of assessment members and deliberation committee members. These assessments are carried out based on a standard provided Ministry of land transport and maritime affairs and environment. However, opinion difference of assessment standards could be occurred due to diversity of understanding for a standard or subjectivity of committee member. In this paper, We discussed the primary cause of score difference after analyzed assessment standard for the site, transportation, energy and resources, ecological environment, indoor environment in five different Apartment Houses located in Seoul. At a result, score difference was at least 3 points in each section except indoor environment and total score difference of housing complex is by 10 points. To improve these problems, educational program should be activated and guide for assessment standard should be published.

  • This study investigates the standard, duration period and excess mortality of extreme heat using the standardized daily mortality data from 1991 to 2004, establishing a standard threshold Criteria for Heat Health Watch Warning System in Korea. It ultimately aims to provide the guidance in building up Heat Health Watch Warning System for Korea by suggesting the standard to quantify thermal stress from heat. The standard threshold Criteria for Heat Health Watch Warning System for Seoul metropolitan city takes into account both daily maximum temperature and daily maximum heat index(HI) and consists of four phases; caution, extreme caution, danger, and extreme danger. Extreme caution phase and danger phase are used as the advisory and warning of extreme heat, respectively. Since the nationwide distribution of the frequency of extreme heat day and the excess mortality rate shows little difference across regions, the standard threshold Criteria for Heat Health Watch Warning System for Seoul metropolitan city can be used for other regions.

  • The contents of geographical education present too inclusive and abstract regard as criteria in an existing curriculum. And geographical education oneself's system is difficult because they are set to the one part of educational side. This study pursuit to make content standard of geographical education based on geography as an alternative. This paper present standard setting up 5 steps. They are Ultimate Theme, Basic Theme, Major Standard, Standard, Detailed Standard. Ultimate Theme is discern geographical education whole : understand of interaction human and environment, understand of place and region, understand of interaction human and region. Basic Theme is concrete of ultimate theme ; geographical skill, physical environment, human environment, place and region, interaction of human and region. Standard is concrete and measurable level of basic theme, it is consist of three steps in Major Standard, Standard, Detailed Standard tv level of specification. Major Standard is consist of 17 item, Standard is 48 item, and Detailed Standard is detailed to unit level.

  • Objectives : Job insecurity, such as non-standard work, is reported to have an adverse impact on health, regardless of health behaviors. The aim of this study was to examine the relationship between non-standard employment and health in Korea. Methods : We analyzed a representative weighted sample, which consisted of 2,112 men and 1,237 women, aged 15-64, from the 1998 Korea National Health and Nutrition Examination Survey. Non-standard employment included part-time permanent, short time temporary and daily workers. Self-reported health was used as a health indicator. Results : This study indicated that women were more likely to report poorer health than men with standard jobs. Of all employees, 20.3% were female manual workers. After adjusting for potential confounders, such as age, education, equivalent income, marital, social and self-reported economic status and health behavior factors, nonstandard employment was found to be significantly associated with poor health among female manual workers (OR, 1.86; 95% CI, 1.24 to 2.79). No significant association was found in other working groups Conclusions : Among female manual workers, nonstandard employees reported significantly poorer health compared with standard workers. This result raises concern as there are increasing numbers of non-standard workers, particularly females.

  • The current standard level of Heat Health Watch Warning System consider both daily maximum temperature and daily maximum heat index(HI), but current standard could not consider daily maximum HI due to the difficulties in forecasting when we consider both daily maximum temperature and daily maximum HI and no considering HI because relative humidity could not observed for some regions. So, Newly established standard level of Heat Health Watch Warning System is based on daily maximum temperature exceeding $30^{\circ}C$ for two consecutive days or daily minimum temperature exceeding $25^{\circ}C$ and daily maximum temperature exceeding $30^{\circ}C$. These days are called "extreme heat days". On extreme heat days, the standard of extreme heat advisory is based on daily maximum temperature among exceeding $32.7^{\circ}C$ and not exceeding $34.8^{\circ}C$, and extreme heat warning is based on daily maximum temperature exceeding $34.8^{\circ}C$. ANOVA analysis was carried out using the data of Seoul Metropolitan City in 1994 to check the robustness of the new standard level of Heat Health Watch Warning System from this study, in particular for mortality variable. The results reveal that the new standard specifies excess mortality well, showing significance level of 0.05 in the difference of excess mortality for each phase.

  • This study was a descriptive investigation to identify the influence of nurses' moral sensitivity and safety of their environment on compliance with standard precautions. Participants consisted of 214 nurses in one general hospital and data were collected using a questionnaire that consisted of moral sensitivity, safety of environment and compliance with standard precautions from 1-15 August 2017. Data were evaluated by the independent t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis. The mean scores of moral sensitivity, safety of environment and compliance with standard precautions were 5.05, 5.76 and 4.50, respectively. Moreover, compliance with standard precautions was significantly positively correlated with moral sensitivity and safety of environment. Additionally, multiple regression revealed an $R^2$ of 0.253 with the department (ER, ICU), age and safety environment serving as the major predictor variables for compliance with standard precautions. However, the influence of moral sensitivity on compliance was not identified. Therefore, to increase compliance with standard precautions among nurses, it is necessary to provide continuous educational programs for new nurses, customized programs considering departmental characteristics and administrative support of institutions to enhance safety of the environment.
