Heavy metal remediation in shooting range soil is a challenge over the world. The excessive Pb accumulation in the soil can deteriorate soil quality and fertility. The objectives of this research were to evaluate the efficiency of biochar (BC) in improving the physicochemical and biological properties of the soil and to evaluate its effect on Pb availability in a military shooting range soil. Sandy loam soil was collected from shooting range of Gyeonggi Province, South Korea and was incubated for 30 days with different application rates (0-30% w $w^{-1}$) of BC. The results showed that the addition of BC increased aggregate stability, nitrogen (N) and phosphorus (P) contents, and enzyme activities in soil. Sequential extraction showed that residual and organic bound fractions in the soil amended with BC increased by 33.1 and 16.7%, respectively, and the exchangeable fraction decreased by 93.7% in the soil amended with BC, compared to the unamended soil. We concluded that the application of BC could not only improve physicochemical and biological soil qualities but also stabilize Pb in a shooting range soil.

As a railway is receiving attention as an environment-friendly transportation mode, many high speed, inter-city and urban railway are constructed and remodeled in the world. With this trend, railway RAMS was included in the international standard IEC 62278 in 2002. RAMS activity in domestic market is also increased with this international trend. However, IEC 62278 does not describe the methodology of substantial contents like how reliability target is set although it can be used as an overall guideline when RAMS requirements are included in the purchase specification. That is because RAMS requirements should be set with the specific railway condition. It is required to fully understand the meaning of railway RAMS parameters and apply those correspond to the specific railway system and environment condition especially when a quantitative RAMS requirement is set. In this study, the meaning and characteristics of RAMS parameters applicable to the development of quantitative RAMS requirement of rolling stock is described. And the basic concept of RAMS and the definition of failure that IEC 62278 describes is modified and suggested in order to make more suitable to the development of quantitative RAMS requirement.

국내에 보유하고 있는 여주 유전자원을 대상으로 과실특성과 charantin 함량을 분석하고, 추후 유전자원을 다양한 용도로 활용하고자 수행하였다. 2010년에 선발된 수량이 높은 계통 2점의 charantin 함량을 HPLC 분석한 결과, 착과 후 일수에 따른 함량의 변이를 보였는데, BG1은 착과 후 24일 15일순으로 charantin 함량이 높게 나타나 착과 후반부에 charantin 함량이 높게 나타난 반면 BG7은 착과 후 일수가 13일에 가장 높았고, 16일 19일 순으로 charantin 함량이 높게 나타나 착과 전반부에 charantin 함량이 높아지는 것으로 나타났다. Charantin 성분 함량이 높은 여주품종 선발 및 수확시기 규명을 위하여 한국, 중국, 인도, 일본 등에서 도입한 유전자원 33점과 시판종 1점중 수량이 높은 13점의 과실특성 및 charantin 함량을 HPLC 분석한 결과 charantin 함량이 높은 104615, K169995, 엔에스454을 선발하였다. 따라서 수량이 높은 13점의 여주자원중 charantin 함량이 높았던 K169995나 NS454은 새로운 품종 육성이나 가공용으로 활용할 수 있으며, 수량이 많았던 K161952나 K051434 등은 과실 생산 목적으로 활용할 수 있을 것으로 생각되고, 착과후 시기별로 용도에 따라 수확을 하여 이용하면 좋을 것으로 생각된다.

In 1990s, as the extreme weather events according to the global warming climate change are occurred frequently all around the world and the scale of the damage increases, the developed countries are promoting various policies for reducing greenhouse gas emissions setting the goal of greenhouse gas reduction with the level of State and local government. Especially for the greenhouse gas reduction of buildings and the inducement of eco-friendly design, the green certification system is strengthened with the assessment of energy and greenhouse management, and recently, according to the policy change of climate and energy, the certification system expanded from the buildings to the level of city and district is piloted. So this research is to understand the main contents and the assessment system of domestic green building certification system implemented in March 2013 in response to the policy change of climate and energy and to suggest the basic data for the improvement of present domestic greenhouse certification standard through the analysis of actual certification and the main case analysis of international green certification system. Recently in developed countries, in 1990s, for the reduction of building's greenhouse gas emission and the inducement of eco-friendly design, from the building of LEED, BREEAM, DGNB to the level of city and district such as LEED Neighborhood Development, BREEAM Communities, DGNB Stadtquartiere, the system is expanded and piloted. On the contrary, as for the domestic standard of green building certification system, the distribution ratio according to the assessment items in each category consists of the assessment system based on the buildings, and just the simple adjustment of some items and the improvement of weighted value are performed. Actually, as a result of selecting the 30 districts of apartment housing with the most certification performance by use among the 49 buildings certified by Institute of Land & Housing from December 2014 to July 2016 and analyzing the assessment score, the certification level is determined by the sectors of high distribution like indoor environment and energy not by the ineffective sector of external environment with low distribution so this system has a limitation to perform the practical means for the policy change of climate and energy. Thus for the national green building certification standards, the assessment system in the sector of external environment is to complemented and furthermore, reflecting domestic reality, through the introduction of certification system and the assessment system with the level of city and district, this system should be improved to meet the international certification standard.

Dogs are a very good indicator of the pollution load on the environment. They share people's environment and are exposed to the action of the same pollutants. This study was to estimate the heavy metal contents in dog hairs in domestic districts, and to assess effects of age, sex, feed habits, living area, breeding environment and smoking habit of owner. The mean concentrations of heavy metals in 204 samples were 0.09${\pm}$0.10 ${\mu}g$/g, 0.21${\pm}$0.09 ${\mu}g$/g, 0.82${\pm}$0.09 ${\mu}g$/g and 0.48${\pm}$0.07 ${\mu}g$/g (Cadmium (Cd), Mercury (Hg), Lead (Pb) and Chromium (Cr)) in dog hairs, respectively. Concentrations of Pb, Cd, Hg and Cr in dog hairs in Yeongnam including Ulsan and Seoul, were higher than in Chungchong and Honam, and concentrations of Pb were significantly different (p<0.01). Concentrations of Cd, Hg, Pb and Cr in dog hairs increased with age (p<0.05). Only dogs fed commercial pet foods had significantly higher Cd and Cr concentrations in hairs than dogs fed dog feed and human diet (p<0.01 in Cd and p<0.05 in Cr). Cr concentrations of dog hairsfrom dogs kept on cement floors were the highest of the other environments (p<0.01). Heavy metal concentrations of dogs owned by smokers, were higher than dogs of non-smokers, but there were no significant differences.

Purpose: Since hospitals have a big impact on the natural and social environment, hospitals' sustainability must be considered in various aspects including environmental, social, and economical aspects. So far, research on sustainable hospitals has mainly been conducted on indoor environment, but outdoor space of hospital is as important as well. The purpose of this research is to study the sustainability of hospital outdoor space and to make proposals for improving sustainable regional public hospitals. Methods: Through preceding research analysis and literature review, the concept of sustainable outdoor space of hospital was defined. Also, the evaluation contents of outdoor space were extracted from domestic and foreign green building certification criteria. With this analytic frame, we visited 4 regional public hospitals in Korea, interviewed the facility managers, and analyzed sustainability of hospital outdoor space. Results: Analysis of 4 regional public hospitals reveals that there is a lack of consideration for sustainability in all 4 categories; urban and network, natural environment, community, and user. In terms of community, sustainability has rarely been applied to all four hospitals. The site selection and terrain of the site were essential to sustainability. Implications: Establishing a master plan considering future expansion is critical. Also more attempt to show regional characteristics is needed. It is necessary to design a comprehensive outdoor space that considers sustainability and also healing environment. Level difference in the site can be used as a design element.
