        전과정평과를 통한 유기농자재의 탄소배출량 산정연구 -유기질비료를 중심으로-

        윤성이,권혁준,Yoon, Sung-Yee,Kwon, Hyuk-Jun 한국유기농업학회 2011 韓國有機農業學會誌 Vol.19 No.1

        ● The current world is suffering abnormal climate caused by global warming. The main cause of global warming is greenhouse gas such as carbon dioxide. The carbon labeling system and carbon traceability system being pushed ahead in the agricultural sector is the policy for responding to climate change to reduce greenhouse gas emissions. To make this policy more effective and enhanced, the amount of carbon emissions should be calculated based on the kind of crops or the various businesses in the agricultural sector. Therefore, in order to estimate the accurate amount of carbon emissions, it is necessary to establish carbon dioxide emission intensity of various agricultural materials added onto the agriculture, and to calculate the amount of carbon dioxide emission for each crop according to agricultural production. The purpose of this study is to establish the amount of emission, emission per agricultural materials, of agricultural materials being added for crop production as a basic step, and emission intensity which can be used in the future market in order to estimate accurate amount of carbon emission in all the policies being promoted in the agricultural sector. Therefore, in this study, in order to build LCI D/B about organic fertilizers among many organic materials added onto the organic agriculture sector, one leading company in organic fertilizer production was selected and LCA was conducted for this leading company. We had to build the intensity and integrated average concept of intensity upon the two cases once production farmers for their own consumption and farms besides organic fertilizer company were categorized even if it's little amount. But in this study, individually produced organic fertilizers were excluded. Calculated results are following. Carbon emission of mixed expeller cake fertilizer in organic fertilizer was 1,106,966.89kg-$CO^2$ and emission intensity was 0.01606kg-$CO^2$, respectively. Total emission of mixed organic fertilizers was 241,523.2kg-$CO^2$ and emission intensity was 0.01705kg-$CO^2$. And total emission of organic compound fertilizers was 94,592.66kg-$CO^2$ and emission intensity was 0.01769kg-$CO^2$, respectively.

        유기농자재의 탄소배출량 산정을 위한 전과정평가(LCA) -패화석, 팽연왕겨, 보르도액을 중심으로-

        윤성이,양동욱,Yoon, Sung-Yee,Yang, Dong-Wook 한국유기농업학회 2012 韓國有機農業學會誌 Vol.20 No.4

        Since 1997, Korean Ministry of Knowledge Economy and Ministry of Environment have established data on some 400 basic raw and subsidiary materials and process like energy, petro-chemical, steel, cement, glass, paper, construction materials, transportation, recycling and disposal etc by initiating establishment of LCI database. Regarding agriculture, Rural Development Administration has conducted establishment of LCI database for major farm products like rice, barley, beans, cabbage and radish etc from 2009, and released that they would establish LCI database for 50 items until 2020 later on. The domestic LCI database for seeds, seedling, agrochemical, inorganic, fertilizer and organic fertilizer etc is only at initial stage of establishment, so overseas LCI databases are brought and being used. However, since the domestic and overseas natural environments differ, they fall behind in reliability. Therefore, this study has the purpose to select organic farming materials, survey the production process for various types of organic farming materials and establish LCI database for the effects of greenhouse gas emitted by each crop during the process. As for selecting methods, in this study organic farming materials were selected in the method of direct observation of material and bottom-up method a survey method with focus on the organic farming materials admitted into rice production. For the basic unit of carbon emission amount by the production of 1kg of organic farming material, the software PASS 4.1.1 developed by Korea Accreditation Board under Ministry of Knowledge Economy was used. The study had the goal to ultimately provide basic unit to calculate carbon emission amount in executing many institutions like goal management system and carbon performance display system etc in agricultural sector to be conducted later on. As a result, emission basic units per 1kg of production were calculated to be 0.04968kg-$CO_2$ for oystershells, 0.004692kg-$CO_2$ for expanded rice hull, and 1.029kg-$CO_2$ for bordeaux mixture liquid.

      • 이산화탄소 원단위 산정방법의 문제점 비교분석

        윤성이 한국전과정평가학회 2002 한국전과정평가학회지 Vol.4 No.1

        기후변화협약이나 환경경영, 혹은 청정기술개발 등의 정책을 입안할 때 나름대로의 평가나 검증을 위한 여러 경우의 부문별 원단위를 산정해야 한다. 그러나 아직까지는 원단위의 개념구분조차 제대로 되지 않은 상태에서 전과정평가를 수행하는 경우가 있다. 여기서는 이산화탄소 배출원단위의 종류를 구분하고 배출원단위를 산정할 때 고려해야 하는 내용과 LCA적 접근법을 이용하여 원단위를 계산할 때 원단위의 종류 및 주의해야 할 내용 등을 고찰하였다. 이산화탄소 배출원단위의 종류는 크게 산업섹터별 원단위, 제품별 원단위, 소재별 원단위로 나누어 분석하였으며 제품별 원단위는 산업일반소비제품과 일차화석에너지(석탄, 석유, 천연가스 등), 전력을 중심으로 원단위를 검토하였다. 각기 배출원단위는 그 용도가 다르고 계산방식이 다르므로 원단위 자체의 산정방법에 대한 오차를 최대한 줄여나가야 한다. 또한 환경성평가를 수행할 때는 정확한 이해가 뒷받침되는 적절한 배출원단위의 사용이 적극 장려되어야 할 것이다. They should calculate CO₂ basic units that are classified by sections in various cases for assessment and verification when Drafting a policy of Framework convention on climate change, Environmental Management or Development of Cleaner production Technology ect. But up to now there are instances where they carry out LCA with a unclassified general idea of CO₂ basic units. In this work we have classified types of CO₂ basic units, also studied considerable respects in calculation of CO₂ basic units and types of CO₂ basic units when we calculate of CO₂ basic units through the LCA-approach method. We divided types of CO₂ basic units into basic units by industrial sector, products and material moreover devided basic units by products are divided into industry general consumption products, simple fossile energy(coal, petroleum, natural gas ect.) and electricity. Uses and calculation methods of each CO₂ basic unit are different therefore we should reduce the error on a way for a calculation of CO₂ basic units. And it promotes to use appropriate CO₂ basic units with correct understanding when carry out LCA.

        뉴미디어 확산과 선거의 변화

        윤성이 한국방송공사 2014 방송 문화 연구 Vol.26 No.2

        The proliferation of new media is changing the meaning and function of the election as well as the power structure surrounding the election campaign. Unlike the modern period in which political parties and candidates took the lead in campaigns, in the post-modern period the role of voters network using new media is enhanced ranging from making election pledges to mobilizing supports. As moving on from pre-modern to modern and to post-modern period, the axis of election power transferred from political party to candidates and to voters. In accordance with the proliferation of new media the institutional meanings of the election is also changing. While the elected representatives had the power of trustee in the industrial society, in the era of new media their role is limited to the delegate who just faithfully represent demands of voters. In the new media era, political intermediary institutions such as election and political party become weak and citizens’ direct participation becomes more active. Therefore participatory democracy will have a higher affinity with the new media era, in which citizens actively participate in the policy making process.

        온라인 정치참여 연구의 동향과 쟁점 : 인터넷선거 연구를 중심으로

        윤성이 한국정보사회진흥원 2008 정보화정책 Vol.15 No.3

        온라인 정치참여 연구에 있어 가장 핵심적인 연구주제는 인터넷의 활용이 정치참여에 미치는 영향이다. 즉 인터넷이 정치적 무관심층들을 새로운 참여자로 만들 수 있을 것인지에 연구초점을 맞춰왔다. 지금까지의 연구는 온라인 정치참여 역시 오프라인 정치참여 구조를 그대로 답습할 것이라는 강화가설과 새로운 정치참여 집단을 만들 것이라는 동원가설로 양분되어 있다. 최근 이 분야 연구에서는 이러한 양분법적 시각이 갖는 한계를 지적하면서 맥락화 모델과 같은 새로운 접근법을 제시하고 있다. 한국의 온라인 정치참여에 관한 연구 역시 인터넷 활용이 참여의 위기라는 대의민주주의의 문제를 해결할 수 있을 것인가에 초점을 맞춰왔다. 이에 관한 실증적 연구는 16대 총선부터 시작되었으며 인터넷 활용이 투표참여에 미치는 영향이 주요 연구주제였다. 초창기 연구에 비해 17대 총선과 17대 대선 연구에서는 독립변수(인터넷 활용)와 종속변수(정치참여)를 보다 세분하여 동원론과 강화론을 검증하는 작업이 이뤄졌다. 온라인 정치참여 연구가 향후 극복해야 될 과제로 선별효과의 문제를 해결함으로써 인터넷 활용과 정치참여 사이의 인과관계를 보다 분명히 규명하는 작업, 그리고 온라인 정치참여 연구의 독립변수인 인터넷 활용과 종속변수인 정치참여의 개념을 세분화하는 작업이 남아있다. A main issue in the study of online political participation is to reveal a relation between Internet use pattern and level of political participation. Studies in this area have tried to solve a question whether the Internet creates new political participation. Two contradictory hypothesis have been suggested and tested to reveal an impact of Internet on political participation. The one is mobilization hypothesis which argues the Internet can create new political participation. The other is reinforcement hypothesis which rebuts an impact of the Internet and prospects that the Internet will reinforce the current pattern of political participation. In the future study of online political participation two research problems need to be dealt with. The first is to examine closely a causal relation between the Internet use pattern and the level of political participation. The second one is to define more specifically independent variable, Interent use, and dependent variable, political participation.
