  • With increasing global interest in environmentally friendly materials and the consequent rise in demand, there is a growing need for alternatives to synthetic fibers, which can cause skin diseases and other side effects. The fashion industry is emphasizing material sustainability owing to concerns about increasing carbon emissions. Moreover, consumers express a strong desire for ecofriendly and sustainable materials. Therefore, clothing brand companies are developing eco-friendly products to enhance their corporate image. Hemp fibers are recognized for their functionality and are utilized as crucial materials in the development of eco-friendly products by global fashion companies. In this study, we produced socks that effectively improve foot health using hemp stem bark extract fibers and demonstrated the positive efficacy of natural fibers through functional and wearability evaluations. Hemp stem bark extract fibers showed 99.9% antimicrobial effectiveness against bacteria responsible for sweat-induced bacterial proliferation and odor, when blended with lyocell fibers and woven into fabric to manufacture socks. Wearability evaluations of these terry cloth socks confirmed a reduction in foot odor and fatigue among the participants with a consumer satisfaction of 4.63/5. These findings confirm the effectiveness and positive impact of the natural antimicrobial properties of hemp fibers and terry cloth structure in improving foot health.

  • This study aims to compare the differences in the carbon neutral agendas of the two countries based on the differing interest positions of the media in the two countries, as well as to analyze the carbon neutral media coverage in South Korea and China. It also seeks to identify the major topics emphasized in the carbon neutral news agenda setting process in the two countries. A total of 49,227 news articles from South Korea and 105,680 news articles from China, covering the period from the declaration of carbon neutrality in both countries in 2020 to May 9, 2022, were collected. CONCOR and topic modeling analyses were performed on these texts. The results found that South Korean media showed a preference for covering carbon neutrality from the perspective of its inhabitants, whereas Chinese media demonstrated a preference for covering carbon neutrality from the viewpoint of the nation. The discourses on coverages largely focus on areas such as energy strategy, business strategy, industrial growth, and international cooperation, with an obvious lack of discourse on the environment. The findings of this study expect to serve as a primary reference in establishing a news coverage strategy which is environmentally sustainable for the media.

  • 급속한 경제성장과 산업화는 오픈스페이스의 감소, 환경 훼손, 교통체증, 무분별한 도시성장 등 심각한 도시문제를 야기시키고 있으며, 국토의 효율적인 보전 및 관리가 되지 않아 다양한 사회갈등이 야기되었다. 이로 인해 많은 학자와 정부는 친환경적인 계획을 수립하여 관리함으로써 지속가능한 발전을 실현하고자 노력하고 있다. 이러한 배경 하에 본 연구는 대한민국을 대상으로 미래 토지피복 변화에 따른 생태계의 기능적 변화를 분석하고자 한다. 이를 위해 통계청의 추계 인구수와 로지스틱 회귀분석을 이용한 도시성장확률지도를 작성하여 2010~2060년의 토지피복 변화를 예측하였고, Costanza의 계수를 이용하여 생태계 용역가치를 분석하였다. 분석결과 시나리오 1의 생태계 용역가치는 6,783~7,092백만 USD로 나타났고, 시나리오 2는 시나리오 1에 비하여 2.9~7.6백만 USD가 감소한 6,775~7,089백만 USD로 나타났다. 이 같은 결과는 시나리오 2의 경우 개발관점에서 도시가 성장함에 따라 상대적으로 보전가치가 높은 농업지역과 습지지역의 많은 면적이 훼손되어 생태계 용역가치가 감소하는 것으로 나타났다. 따라서 지속가능한 개발을 위해서는 친환경적이고 체계적인 도시개발을 통해 환경적 보호가 이루어져야 함을 알 수 있다. 또한, 환경정책수행에 따른 환경적 가치를 정량적으로 분석함으로써 정책입안자 및 도시개발자들에게 판단기준을 제시해줄 수 있을 것으로 판단된다. 향후 정확한 도시성장 수요량을 산정하고, 이를 바탕으로 도시성장예측모델링을 수행하여 보다 정밀한 도시성장예측 분석이 이루어져야 할 것으로 판단된다.

  • The Equator Principles are a set of voluntary environmental and social guidelines for ethical project finance. These principles commit banks and other signatories to not finance projects that fail to meet these guidelines. The principles were conceived in 2002 on an initiative of the International Finance Corporation and launched in 2003. Since then, dozens of major banks have adopted the Principles, and with these banks among them accounting for more than three quarters of all project loan market volume the Principles have become the de facto standard for all banks and investors on how to deal with potential social and environmental effects of projects to be financed. While regarding the Principles an important initiative, NGOs have criticised the Principles for not producing real changes in financing activities and for allowing projects to go through that should have been screened out by the Principles, such as the Sakhalin-II oil and gas project in Russia. In early 2006, a process of revision of the principles was begun. The Equator Principles state that endorsing banks will only provide loans directly to projects under the following circumstances: - The risk of the project is categorized in accordance with internal guidelines based upon the environmental and social screening criteria of the International Finance Corporation (IFC). - For all medium or high risk projects (Category A and B projects), sponsors complete an Environmental Assessment, the preparation of which must meet certain requirements and satisfactorily address key environmental and social issues. - The Environmental Assessment report addresses baseline environmental and social conditions, requirements under host country laws and regulations, applicable international treaties and agreements, sustainable development and use of renewable natural resources, protection of human health, cultural properties, and biodiversity, including endangered species and sensitive ecosystems, use of dangerous substances, major hazards, occupational health and safety, fire prevention and life safety, socio-economic impacts, land acquisition and land use, involuntary resettlement, impacts on indigenous peoples and communities, cumulative impacts of existing projects, the proposed project, and anticipated future projects, participation of affected parties in the design, review and implementation of the project, consideration of feasible environmentally and socially preferable alternatives, efficient production, delivery and use of energy, pollution prevention and waste minimization, pollution controls (liquid effluents and air emissions) and solid and chemical waste management. - Based on the Environmental Assessment, Equator banks then make agreements with their clients on how they mitigate, monitor and manage those risks through an 'Environmental Management Plan'. Compliance with the plan is required in the covenant. If the borrower doesn't comply with the agreed terms, the bank will take corrective action, which if unsuccessful, could ultimately result in the bank canceling the loan and demanding immediate repayment. - For risky projects, the borrower consults with stakeholders (NGO's and project affected groups) and provides them with information on the risks of the project. - If necessary, an expert is consulted. The Principles only apply to projects over 50 million US dollars, which, according to the Equator Principles website, represent 97% of the total market. In early 2006, the financial institutions behind the Principles launched stakeholder consultations and negotiations aimed at revising the principles. The draft revised principles were met with criticism from NGO stakeholders, who in a joint position paper argued that the draft fails by ignoring the most serious critiques of the principles: a lack of consistent and rigorous implementation.

  • 국가 비전으로 천명된 녹색성장의 배경에는 기후변화와 지속가능한 발전 세계화, 현 정권의 대선공약, 아 태지역의 경제성장 논리가 자리 잡고 있다. 녹색성장은 지속가능한 발전에 비해 환경보전과 사회정의에 대한 배려가 부족하다. 명호를 '녹색발전'으로 변경하고, 사회통합부분이 수용되어야 한다. 기후변화는 지리학에 대한 수요를 증가시킬 것이고 그 자체는 지라학의 실험장이 될 것이다. 지구촌의 현안은 점차 복잡계의 특성으로 이행되고 있다. 이러한 경향은 지구시스템학과 지속가능학과 같은 연구 응용 프로그램을 태동시켰으며, 지리학은 이들 프로그램의 포털로 간주되고 있다. 녹색지역개발을 위해서는 전체론적 관점에서 지역의 잠재력을 파악하고 적정한 발전목표를 탐구해야 한다. 세계적 생산 네트워크에 편입할 수 있는 잠재력을 지닌 지역과 그렇지 아니한 지역은 서로 발전방향이 달라야 한다. 생태적으로 건강한 도시지역을 위해서는 지역 내에서 생산과 소비가 긴밀히 연결되어 순환 고리가 형성되도록 지역발전전략이 선택되어야 한다. 녹색생활양식은 저탄소의 기초를 이룬다. 한반도의 기후환경이 변하고 에너지 효율화가 요구되는 조건에서 녹색발전을 성취하기 위해서는 지리학적 통찰력과 상상력이 절실하다.

  • Energy security is a topic of high importance to many countries throughout the world. Countries with access to vast energy supplies enjoy all of the economic and political benefits that come with controlling a highly sought after commodity. Given the desire to diversify away from fossil fuels due to rising environmental and economic concerns, there are limited technology options available for baseload electricity generation. Further complicating this issue is the desire for energy sources to be sustainable and globally scalable in addition to being economic and environmentally benign. Nuclear energy in its current form meets many but not all of these attributes. In order to address these limitations, TerraPower, LLC has developed the Traveling Wave Reactor (TWR) which is a near-term deployable and truly sustainable energy solution that is globally scalable for the indefinite future. The fast neutron spectrum allows up to a ~30-fold gain in fuel utilization efficiency when compared to conventional light water reactors utilizing enriched fuel. When compared to other fast reactors, TWRs represent the lowest cost alternative to enjoy the energy security benefits of an advanced nuclear fuel cycle without the associated proliferation concerns of chemical reprocessing. On a country level, this represents a significant savings in the energy generation infrastructure for several reasons 1) no reprocessing plants need to be built, 2) a reduced number of enrichment plants need to be built, 3) reduced waste production results in a lower repository capacity requirement and reduced waste transportation costs and 4) less uranium ore needs to be mined or purchased since natural or depleted uranium can be used directly as fuel. With advanced technological development and added cost, TWRs are also capable of reusing both their own used fuel and used fuel from LWRs, thereby eliminating the need for enrichment in the longer term and reducing the overall societal waste burden. This paper describes the origins and current status of the TWR development program at TerraPower, LLC. Some of the areas covered include the key TWR design challenges and brief descriptions of TWR-Prototype (TWR-P) reactor. Selected information on the TWR-P core designs are also provided in the areas of neutronic, thermal hydraulic and fuel performance. The TWR-P plant design is also described in such areas as; system design descriptions, mechanical design, and safety performance.

  • Although national and regional environmentally friend agriculture (EFA) and food development programmes such as the Life-Food Development Plan (LFDP) have been established in Korea, some policy measures in these programmes seem to be unsuitable for Korean organic farming development. Policy measures tend to support external input purchases of organic fertilizers rather than market development actions such as providing consumer information, research, education, training and statistical data collection. The development of an organic action plan (OAP) for Korea is therefore considered essential for the sustainable future of organic farming in Korea. The purposes of OAP are 1) to define and set the clear goals/targets for the organic sector development, 2) to integrate various organic stakeholders and public institutions in partnership, 3)to focus on specific issues with tailored measures and 4) to integrate and develop different policy measures (Stolze, 2005). Most EU member state countries have developed their own OAPs and each reflects its own priorities with regard to organic sector development. This study compares and contrasts the Welsh, England and EU OAP with the Korean Jeonnam Life-Food Development Plan (LFDP) in order to facilitate the development of the organic food and farming sector in Korea. Early action plan, for example, the first Welsh OAP(1999) focused support on developing the supply of organic products whereas later action plans (e.g. England OAPs in 2002 and 2004 and the second Welsh OAP in 2005) focussed more on developing consumer demands for organic products. The EU OAP (2004) also aims at market support related to consumer demand and then organic farming production for its environmental and other social benefits. OAPs not only provide specific issue-solving tools but also perform a role as providing a focus for organic sector development as a whole. The Korean LFDP provides issue-solving tools but plays no regulatory role such as policy development, harmonizing various policy measures and conflicting factors and providing evaluation tools for further development. A national-level OAP could also facilitate international trade of organic products. To achieve better harmonized and sustainable approaches for the Korean organic industry, National- as well as regional- regulatory policy systems are urgently required in the form of an Organic Action Plan.

  • 지구온난화를 일으키는 주요 온실가스가 이산화탄소임이 공표되고, 이의 배출 감축을 유도하기 위한 국내외적 규제가 강화됨에 따라 국내 건설산업에서도 생산과정에서 배출되는 이산화탄소량을 줄이기 위한 노력이 절실히 요구되고 있다. 이의 일환으로서 본 연구는 심각한 이산화탄소 배출원 중 하나인 건설폐기물에 대해 전과정평가(LCA)를 수행하여 건설폐기물로 인해 배출되는 이산화탄소의 특성을 파악하고, 그 결과를 토대로 건설현장에서 이산화탄소 배출량을 효과적으로 줄일 수 있는 폐기물 관리방안 수립 기준을 제시하고자 하였다. 전과정평가(LCA) 결과, 자재별로는 철근류, 가설자재류, 시멘트류, 레미콘, 콘크리트 제품, 타일 등의 자재가 폐기물로 인한 전체 이산화탄소 배출량 중 95% 정도를 배출하는 것으로 나타났다. 이들 자재의 이산화탄소 배출량이 많은 원인은 폐기물 발생량보다는 자재 생산에 필요한 단위 이산화탄소 발생량이 높기 때문인 것으로 분석되었다. 공종별로는 철근콘크리트공사, 미장공사, 가설공사 등과 같이 전체 공정 중 초중반에 걸쳐 수행되는 공종에서 발생하는 이산화탄소 배출량이 전체 공종 중 92% 이상 차지하는 것으로 조사되었다. 반면, 폐기물 관리자들은 공정 중후반에 수행되는 마감공종의 폐기물 관리에 집중하고 있어서 폐기물로 인한 이산화탄소 배출량 증가 원인 중 하나로 작용하고 있음을 파악하였다. 또한, 전과정평가(LCA) 결과를 반영한 폐기물 관리방안 수립 기준을 제시함으로써, 건설현장에서 폐기물 관리방안 수립 시 활용할 수 있도록 하였다.

  • 최근 친환경건축물인증제도, 주택성능등급표시제도를 비롯하여 실내공기환경에 대한 기준, 친환경상품인증기준 등 환경관련 제도 및 규정이 마련되면서 공동주택의 신축 및 리모델링 공사에 이에 대한 고려가 필요한 상황이다. 특히 공동주택 리모델링 공사는 거주자가 사전에 정해진 상태에서 공사를 진행하므로 이들에 대한 의견수렴과 사용되는 소재에 대한 요구분석이 신축에 비해 중요하다는 특성이 있다. 하지만 현재 국내에서 시행 중에 있거나 최근 완료된 리모델링 공사의 시공자는 친환경 소재 적용에 대한 거주자의 적극적인 의견수렴 과정이 미비하였고, 친환경상품인증원의 최우수 등급을 받은 친환경 제품을 거주자의 요구에 의해 적용한다기 보다는 공동주택의 홍보의 일환으로 사용하고 있는 실정이었다. 또한 공동주택 리모델링 거주자는 친환경 제품의 인증기준에 대한 이해가 부족하여 친환경 제품의 등급을 맹목적으로 신뢰하는 경우가 있었고 적용되는 친환경 소재에 대한 요구가 매우 정성적인 특징이 있다. 따라서 공동주택 리모델링 거주자의 친환경 소재에 대한 요구사항을 조사하고 이를 정량적으로 분석하여 만족도를 극대화 할 수 있는 친환경 소재를 리모델링 공사에 적용하여야 한다.

  • The management of soil chemical properties is very important to sustainable agriculture of many horticultural crops, including cucumber. This study was conducted to find the optimal soil properties of environmentally friendly agriculture in controlled horticulture. Soil chemical properties of 267 samples were collected from soil in Chungnam Province. The average of pH, EC, OM, available $P_2O_5$, exchangeable K, Ca, and Mg was 6.1, $5.38dS\;m^{-1}$, $34g\;kg^{-1}$, $1,321mg\;kg^{-1}$, $1.50cmol_c\;kg{-1}$, $10.3cmol_c\;kg{-1}$, and $3.4cmol_c\;kg{-1}$, respectively. The organic matter content in silty clay loam was significantly higher than in the other soil textures, whereas the pH, EC, exchangeable K, and Mg in loamy fine sand showed significantly lower among soil textures. The EC value and exchangeable Mg concentration were highest in mountain foot-slope soils. The frequency distribution within optimum range of soil chemical properties was 26.2%, 30.3%, 2.3%, 3.8%, 3.4%, and 6.7% for pH, OM, available $P_2O_5$, exchangeable K, Ca, and Mg, respectively. Especially, excessive portion of available $P_2O_5$ and exchangeable Ca were 94.0% and 94.4%, respectively. The EC value and organic matter content of soil samples were positive correlation with all chemical properties except soil pH. In principle component analysis of chemical properties in soil samples, the percentage of variance explained by PC 1 was 52.2%, while PC 2 explained 21.3% of the variance, for a cumulative total of 73.5%. In conclusion, these results are considered to improve soil nutrient management for sustainable controlled horticulture.
