The spent fuel is classified based on the arrangement of fuel rods, which is considered the primary characteristic data for selecting nuclear fuel. The reason for prioritizing the classification by fuel rod arrangement is that it has the greatest physical impact on the production, supply, operation, reactor type, rack size within the containment vessel, and specifications for the basket in the future dry storage system. Additionally, as mentioned earlier, various meanings of nuclear fuel types are distinguished according to the arrangement of fuel rod. The burnup and cooling period ranges are also important factors in the characterization analysis for the selection of spent fuel, the burnup range was set for both low and high burnup ranges and the cooling period is necessary to consider the reliability during handling of nuclear fuel thermal distribution within the storage system

오늘날 한국 정치의 키워드라고 하면 단연 ‘음모론’이란 언어이다. 어느 사건이나, 정치적인 이슈가 발현하게 되면 어김없이 언론, 뉴스, 개인 방송, SNS를 통해 ‘음모론’이란 단어가 등장한다. ‘천안함 음모론’, ‘총선 음모론’, ‘코로나 음모론’은 물론이거니와, ‘美 대선 음모론’, ‘9.11 음모론’ 등 자극적인 제목으로 대중들의 관심을 끈다. 그런데 우리 사회는 ‘음모론’이라는 딱지를 붙이는 순간, ‘음모론’에 대한 합리적 의심도 하지 않은 체, 비합리적이고, 편집증적인 환자 취급을 하게 된다. 하지만 ‘음모론’이 어떻게 발생하고, 정치적으로 어떠한 기능을 하고 있는지, ‘음모론’의 의미를 재해석하는 학문적인 연구도 필요하다. 본 연구는 음모와 관련되었던 역사적 사건들이나, 일상생활에 듣고 보는 정치적 비밀, 음모로 포장된 진실들을 음모론으로 포괄하여 살펴보았다. 음모론은 개인의 편협한 사고로 사회를 왜곡해서 보는 관점이지만, 음모론이 사회를 바라보는 비판적 의식을 가져온다는 긍정적인 특징을 7가지로 분석하였다. 반면 음모론은 검증은 가능하지만, 과학과 실험에 의해 반증 가능성이 없기 때문에 음모론의 한계가 있다고 칼 포퍼의 논의를 빌려 음모 론의 한계를 설명하였다. 그럼에도 불구하고, 불확실성의 시대를 해석할 수 있는 하나의 대안적 지식으로서의 음모론을 좀 더 체계적이고, 비판적인 이론으로서의 학문적 검토가 필요하다고 판단된다.

In present study, the coffee residue was analyzed to finding out physicochemical characteristics and TG analysis that can simulate a pyrolytic kinetic, while comparing with that of chicken residue and food waste. The higher heating value (HHV) of coffee residue was 5,250 kcal/kg that is higher than that of wood pellet (4,300 kcal/kg), Additionally, it showed a good activation energy 72 kJ/mol which is similar with that of other biomass, such as saw dust, wood-chip and so on. It means that the coffee residue is meeting to standard for highest quality of wood pellet, and it would be used as a biomass in the future. However, it never become a fuel without main fuel, such as coal and wood, because its discharge amount is too little. Thus, it has to be applied to existing process, such as power plant which must to meet a RPS regulation. For this, physicochemical characteristics of various biomass have to be analyzed, while considering a discharge amount of them. Therefore, the research result would be provided to reclassification coffee residue to biomass from food wastes in the future.

This study tried to seek the plan to recycle chicken residues (bones of seasoned spicy chicken and fried chicken) which are sent out thermally after chickens are delivered to homes and people eat them by grasping their basic characteristics. The analytical results of the weight reduction rate through the change before and after the weight is reduced have found that the average weight reduction rate of 38.0% is shown in the seasoned spicy chickens and fried chickens. The analytical results of low-heating value of chicken residues to grasp the thermochemical characteristics have found that the seasons spice chickens and fried chickens satisfy the SRF quality basis, 3,500 kcal/kg as 5,020.9 kcal/kg and 5,295.2 kcal/kg respectively. On the other hand, the analytical result of TG has found that the thermal weight reduction rate is relatively clear in the fried chickens. It is inferred that creation of the fried chickens is more uniform than that of the seasoned spicy chickens and the effect of bound water is lower than other biodegradable substances. And it is judged that the potential that they can be utilized as sold fuel without any separate preprocessing through the drying process only is shown.
