It is introduced an outstanding book about an important topic in occupational and environmental sciences i.e., the opportunities and challenges that may be connected with increasing the use and distribution of rare earth elements. These chemically similar elements, comprising the lanthanides, scandium, and yttrium, are involved in a number of essential technological applications, and their effects raise a number of human health issues of relevance to the occupational and environmental sciences. The book that I introduced here, "Rare Earth Elements in Human and Environmental Health; At the Crossroads between Toxicity and Safety" edited by Giovanni Pagano (Pan Stanford Publishing Pte. Ltd., Temasek Boulevard, Singapore) represents a break from that situation. It is essential to increase our knowledge about the environmental fate and biological effects of these technologically important metals in order to prevent unforeseen long-term man-made consequences to human health. This book is likely to become an important resource for scientists, engineers, and decision makers who understand the need for sensible exploitation of this resource.

Background: Construction industry is among the most hazardous industries, and needs a comprehensive and simple-to-administer tool to continuously assess and promote its health and safety performance. Methods: Through the study of various standard systems (mainly Health, Safety, and Environment Management System; Occupational Health and Safety Assessment Series 180001; and British Standard, occupational health and safety management systems-Guide 8800), seven main elements were determined for the desired framework, and then, by reviewing literature, factors affecting these main elements were determined. The relative importance of each element and its related factors was calculated at organizational and project levels. The provided framework was then implemented in three construction companies, and results were compared together. Results: The results of the study show that the relative importance of the main elements and their related factors differ between organizational and project levels: leadership and commitment are the most important elements at the organization level, whereas risk assessment and management are most important at the project level. Conclusion: The present study demonstrated that the framework is easy to administer, and by interpreting the results, the main factors leading to the present condition of companies can be determined.

Recently in most homes, children are mostly cared in early childhood education facilities. However, the increased number of safety accidents on children cared in such facilities has become a social issue. For that, the purpose of this study is to suggest interior environmental planning elements to improve safety level of early childhood education facilities. This study was carried out by performing literature review analysis and survey. First, in total of 42 environmental planning elements that can be applied domestically were derived from analyzing safety related guidelines for children facilities located both domestically and internationally then a survey was carried out targeted for teachers and staffs in the facilities on importance of the factors. The results of this study are as followings. First, it is required to intensify the level of safety related training for teachers and staffs in the facilities including better treatment for them. Second, the necessity of safety environment by each space in such facilities is required to be approached upon the level of child activities. Third, facilities planning and finalizing planning are important for improving safety of early childhood education facilities. Forth, from factor analysis on the extracted environmental planning elements that are considered as important by the teachers from both day care centers and kindergartens, they were categorized in 5 groups including 'collision and fall prevention plan', 'physical characteristic consideration plan', 'evacuation safety plan', 'lock security plan' and 'outer control plan'. It is fair to say that constructing a better safety environment for children can be achieved by the environmental planning factors by this study.

It is very important to manage efficient data for safety and maintenance of those constructs. Estimation for structural safety can be evaluated by using data that surveys various structural durability and safety elements. so, it should be based on synthetic and efficient data that includes a variety of related safety elements obtained from a structure. It will subsequently be managed properly and economically. Accordingly, we will approach efficient maintenance management using a Geographic Information System (GIS) with data from structural-safety diagnosis and a Global Positioning System (GPS). In this study, we noted that by using the data that measures the factors (crack, incline, settlement etc.) of various structures as evaluate safety degree. And the horizontal coordinate variation/time of structure was monitored using the GPS easily.

The purpose of this study was to investigate consumer concerns about hazardous elements on foods and recognition of the roles of government, food producers, and consumers in securing food safety. The data were collected from the 443 adult consumers living in Seoul, Busan, Daegu, Incheon, Kwangju and Daejeon through a self-administered questionnaire. Frequencies, t tests, analysis of variance and Duncan's multiple range tests were conducted using SPSS Windows. The results of the survey were as follows: (1) the respondents were worried about health risks related to hazardous elements on foods, (2) many respondents were more worried about preservatives of imported foods than those of domestic foods, and (3) most respondents mentioned that observance of enforcement regulations by producers was the most important factor for ensuring food safety in the future. These results imply that regulations regarding the safety of imported foods should be increased.
