  • Background: A common genetic variant rs3757318, located in intron of C6orf97, was firstly identified to be associated with breast cancer (BC) risk by a genome-wide association (GWA) study. However, subsequent validation studies with different ethnicities have yielded conflicting results. Materials and Methods: We performed a meta-analysis to synthesize all available data for evaluating the precise effect of this variant on BC susceptibility. Results: A total of 8 articles containing 11 studies with 62,891 cases and 65,635 controls were included in this meta-analysis. When compared to the G allele, the rs3757318-A allele was significantly associated with BC risk with the pooled OR of 1.21 (95% CI=1.15 - 1.29, P<0.001) but with obvious between-study heterogeneity (P=0.040). Stratified analysis suggested that diversity of ethnicity along with control source may explain part of the heterogeneity. Similarly, significant associations were also identified in heterozygote, homozygote, dominant and recessive genetic models. Sensitivity and publication bias analyses indicated robust stability of our results. Conclusions: Our present meta-analysis demonstrated that the variant rs3757318 is associated with increased BC risk. Nevertheless, further studies are needed to clarify the underlying biological mechanisms.

  • The purpose of this study is to overcome the realistic pressure and the limit of school environmental education and to develop an environmental education program that can provide students, who live in an urban area, have difficulty in contacting with nature, with an opportunity to experience the nature in the school outdoor environment, which is their daily living space and is a ground of environmental education. First, I developed an analytical tool which can be used to determine the degree how the environmental education is related to the school outdoor environment with 8 categories(spaces). And I analyzed the 2007-79 curriculum of lower grade(1 and 2 grades) of the elementary school provided by the Ministry of Education and Human Resources Development by using the analytical tool and found out that this curriculum was suitable for the environmental education utilizing the school outdoor environment. According to this curriculum analysis, the studying subjects which could be suitable for the environmental education utilizing the school outdoor environment were extracted, and based on these subjects, an environmental education program was developed. The environmental education 'in' environment program were composed with 5 modules and 18 activity subjects suitable for students advancement phase, and these activities can be implemented with experiencing, understanding and expressing by using 5 senses. I also proposed a plan that can be used to apply this program continuously to the lower grades(1 and 2 grades) original experience activity class.

  • The object of this study is to show the international safety school operating characteristics certified by Community Safety Promotion Cooperation Center affiliated to the WHO to strengthen safety training course and create safe training environment in accordance with the importance of recently the safety education for students and safe environment in the school education course. It draw the kind of education program to prevent accidents in the elementary and middle school students because of analyzing student safety education program. It also suggest operation characteristics which were divided into physical environment and crime prevention environment.

  • Global environment is getting deteriorated at an alarming rate. Eco-school could be one of the effective solutions to protect our environment and a good sample of architecture to economize in total energies, resources and greenhouse gases. In case of our country, the study of eco-school planning is not sufficient compared with other countries, so this paper would be a good study on the indoor environment of the classroom by surveying their opinions and ideas from the group of users in elementary school. The result of this study shows that the proper installation of building equipment and nature ventilation system is necessary to provide delightful environment for the students and to save the energy. To ensure that we have adequate saving and protection, it is necessary to change the existing appraisal standard.

  • Today's fundamental purpose of environmental education is to fulfill people's desire of living in a pleasant environment and at the same time promoting individualistic and collective environmentally friendly behaviors. In order to achieve these purposes, it is very important that each person holds an environmentally friendly mind that constantly tries to preserve and protect the environment which should be acquired through experiencing the importance of the environment. In order to increases the sense of attachment of people and the natural environment, the direction of environmental education should carry out education on environment related knowledge and the condition of environment damage side by side. The direction of environmental education should consider the cultivating student's awareness for active participation on matters related to the environment and to change their behaviors towards the environment. This study has tested the effect of reflective writing activities about the environment on the environmental sensitivity and willingness to act of 5th grade primary school students. For the sole purpose of this study, 70 students out of 141 5th graders of M Primary School were divided as the experimental group, and another 71 students were divided as the control group. The experimental group participated in 10 activities in where they were asked to express their thoughts and feelings in writing regarding 10 environmental problems occurring near the M Primary School. The control group participated in 10 environmental education lectures focusing on the lecturer. The results were as following. First, the reflective writing activities about the environment were effective in the environmental sensitivity of primary school students. Second, the reflective writing activities about the environment can affect the environmental willingness to act of primary school students. Third, there was a statistically significant correlation between environmental sensitivity and environmental willingness to act.

  • Analysis of the case of the German school acceptance plan was to help complement the limitations of the nation's student accommodation plan will be judged. Therefore, the present study in order to determine what the content covered in the plan of the German student acceptance of Potsdam, Germany, which contains information from the Potsdam school development plan (Schulentwicklungsplan) were analyzed. A scheme suggested in this study was based on the analysis of survey to elementary school in Potsdam and actually surveyed data on educational environment, the result can be summed up as follows; Korea's plan to accommodate students and school development plan (Schulentwicklungsplan) is called, as shown in the case of this study in Potsdam(Germany) student acceptance of the educational environment plans, as well as accommodate students like us, school facility planning and school facilities dealing with the financial investment plan. In addition, the plan as a long-term plan that will ensure the predictability of long-term school facilities to finance investment plans. This study, there are limits to Potsdam, Germany, to analyze the characteristics of Germany's student accommodation plan to represent the characteristics of the students of other cities in Germany and an acceptance plan.

  • In this study, cobalt diselenide ($CoSe_2$) and the composites ($CoSe_2@RGO$) of $CoSe_2$ and reduced graphene oxide (RGO) were synthesized by a facile hydrothermal reaction using cobalt ions and selenide source with or without graphene oxide (GO). The formation of $CoSe_2@RGO$ composites was identified by analysis with X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy and scanning electron microscopy (SEM). Electrochemical analyses demonstrated that the $CoSe_2@RGO$ composites have excellent catalytic activity for the reduction of $I_3{^-}$, possibly indicating a synergetic effect of $CoSe_2$ and RGO. As a consequence, the $CoSe_2@RGO$ composites were applied as a counter electrode in DSSC for the reduction of redox couple electrolyte, and exhibiting the comparable power conversion efficiency (7.01%) to the rare metal platinum (Pt) based photovoltaic device (6.77%).
