The purpose of this study was to examine the realities of physical health conditions of children aged from 0 to 11 for the last decade. On the basis of the analyzed results, the pragmatic and policy issues are as follows : First, in the perspective of child development, studies of physical health are needed for the benefit of integrative development of children. Second, appropriate health education programs suitable for ages of children need to be developed and made compulsory for them. Third, the prohibition of adopting the ranking evaluation in physical education is to be required at the policy level. Forth, for sustainment of the health-related activities for children, the space or facilities specifically prepared for families to exercise and rest are needed. Lastly, new regulations and management systems are needed in order to resolve the safety problems with food for children.

Background: Some of the introduced alien species introduced settle, multiply, and spread to become invasive alien species (IAS) that threaten biodiversity. To prevent this, Korea and other countries legally designate and manage alien species that pose a risk to the environment. Moreover, 2160 alien species have been introduced in South Korea, of which 1826 animals and 334 plants are designated. The inflow of IAS can have negative effects such as ecosystem disturbance, habitat destruction, economic damage, and health damage to humans. To prevent damage caused by the inflow of IAS in advance, species that could potentially pose a risk to the environment if introduced in South Korea were designated as alert alien species (AAS). Results: The designation criteria were in accordance with the "Act on the Conservation and Use of Biological Diversity" and the "Regulations on the Ecological Risk Assessment of AAS and IAS" by the National Institute of Ecology. The analysis result of risk and damage cases indicated that mammals affect predation, competition, human economic activity, virus infection, and parasite infection. Birds have been demonstrated to affect predation, competition, human economic activity, and health. It was indicated that plants intrude on the ecosystem by competing with native species with their high-population density and capacity to multiply and cause allergic inducement. Interestingly, 300 species, including 25 mammals, 7 birds, 84 fishes, 28 amphibians, 22 reptiles, 1 insect, 32 spiders, 1 mollusk, 1 arthropod, and 99 plants, are included in the list of AAS. Conclusions: AAS designation plays a role in preventing the reduction of biodiversity by IAS in South Korea and preserving native species. Moreover, it is determined to provide considerable economic benefits by preventing socio-economic losses and ecological damage.

The present study was conducted to judge the applicability of field quality control by children's goods manufacturers by assessing the contents of heavy metals such as Pb and Cd in outdoor play goods for children through measurement using Portable XRF and comparing the results through detailed analyses using ICP. Heavy metal contents of 711 part samples of 505 products were measured using XRF. According to the results, the ratio of products that exceeded the Pb and Cd content standards specified under the Quality Management and Safety Control of Industrial Products Act were 2.4% and 2.6%. Many products certified for self-regulated safety exceeded the standards and thus it was considered that harmful chemical material centered safety management systems would be necessary. Detailed ICP analyses of some products were compared and the results showed deviations of 0.9~80.8% from XRF results. The reasons for this are deviations in the characteristics of measured cross sections and the homogeneity of samples resulting from sample preparation methods, etc. Therefore, it is considered that field quality control will be applicable if measuring methods are efficiently established based on product characteristics and calibration curve preparation methods are established through quality control.

The shipbuilding and offshore industry is a large and complex assembly industry, which causes many safety accidents. The major accidents in the shipbuilding and offshore industry workplaces are stenosis, falling objects, dust, fire, explosions, and gas poisoning. The accident by worker in this industry mainly has three factors: frequent movement, narrow work space, and increased use of subcontractors. To control these factors, it is necessary to monitor the worker's location and work status. In this paper, a worker location monitoring system using inaudible sound wave was designd that can be used in environments with many metal barriers. The process included deriving stakeholder requirements, transforming to system requirements, designing system architecture, and developing prototype. The prototype was validated by third-party testing agency. As a result, it satisfied the designed performance and verified its feasibility.

본 연구의 목적은 유헬스 시스템의 사용(usage)이라는 행위 의도(behavioral intention)에 미치는 영향 요인들 간의 관계에서 건강개인정보(health privacy information)의 조절적 효과(moderating effect)를 분석하는데 있다. 합리적 행동이론에 근거한 모형 내 연구가설로서 자기효능(self-effiacy) 및 인지된 유용성(perceived usefulness)은 유헬스 시스템의 행위 의도(behavioral intention)에 긍정적인 (positive) 영향을 미칠 것이며, 그 경로(path)에서 사용자의 건강개인정보 요인이 각 경로에서 어떤 영향을 미칠 것으로 제시하였다. 본 연구는 그 제시된 연구모형을 검증하기 위해서 PLS-SEM 방법론을 활용하였다. 분석 결과, 제시된 모형 내에서 건강개인정보의 조절적 효과가 R2 설명력의 증가치에 의해 어느 정도의 영향을 미친다고 볼 수 있지만, 조절변수로의 역할보다는 인지적 유용성(perceived usefulness)에 영향을 미치는 독립변수의 역할에 부합됨을 알 수 있었다.

The objective of ECMS(Environmentally Conscious Manufacturing Systems) is to consider environmental effects through the entire product life cycle from product development stage to design, manufacturing, supplying, using and disposing stage. Recently, environment-oriented recycling, reusing and manufacturing technologies have been researched actively in every engineering fields. In the field of chemical engineering, HHS(Health Hazard Scores) which classifies and analyzes hazardous materials in production processes has been presented. Metal cutting processes also have a lot of harmful factors, and especially hazardous components in cutting fluids have been known to have a bad effect on workers and working area. However, research works such as HHS have been little accomplished in metal cutting processes. In this research, a environmentally conscious machining process is presented by classifying hazardous components in cutting fluids, by using LCA(Life Cycle Assessments) and HHS method, and by evaluating environmental effects from cutting fluids.
