박지혜,김영희,정미원,Park, Jihye,Kim, Younghee,Jung, Miewon 한국세라믹학회 2012 한국세라믹학회지 Vol.49 No.5

Porous SiC ceramics were prepared by using recycled SiC sludge, which is an industrial waste generated from solar cell industry. Polycarbosilane derivatives, such as polycarbosilane (PCS), polyphenylcarbosilane (PPCS) and hydridopolycarbosilane (HPCS) were used as binding agents for the fabrication of porous SiC ceramics at $1800^{\circ}C$ under Ar atmosphere. The effects of the various binding agents having different C/Si ratios were discussed on the sintering and porosity of the SiC ceramics. The prepared porous SiC ceramics were characterized by X-ray Diffraction (XRD) and Field-Emission Scanning Electron Microscope (FE-SEM). Thermal conductivity and porosity of SiC ceramics were measured at room temperature, and they were 56.7W/mK and 29.8%, respectively.

원전 방사성 콘크리트 기계적 절단의 방사성 에어로졸에 대한 작업자 내부피폭선량 평가

박지혜,양원석,채낙규,이민호,최성열,Park, Jihye,Yang, Wonseok,Chae, Nakkyu,Lee, Minho,Choi, Sungyeol 한국방사성폐기물학회 2020 방사성폐기물학회지 Vol.18 No.2

원전 해체 공정 중 다량의 콘크리트 방사성 폐기물의 절단 과정에서 불가피하게 방사성 에어로졸이 생성된다. 방사성 에어로졸은 인체 호흡기 흡착에 의한 내부피폭을 유발하기 때문에 작업자의 방사선 방호를 위한 내부피폭평가가 필수적으로 시행되어야 한다. 그러나 실제 작업환경의 에어로졸 특성값을 사용하기에는 선행 연구가 미비하며 콘크리트에 포함된 방사성 핵종의 수가 많기 때문에 정확한 작업자 내부피폭평가를 위해서는 상당한 시간과 인력이 필요하다. 따라서, 본 연구에서는 사전 연구된 콘크리트 에어로졸 특성값을 활용하여 원전 해체 전 절단 작업자의 내부 피폭량을 빠르게 예측할 수 있는 새로운 방법론을 제시하고자 한다. 본 연구팀은 콘크리트 절단 시 발생하는 사전 연구에서 발표된 에어로졸의 수농도 크기 분포데이터를 뉴턴-랩슨법을 이용하여 피폭평가 계산에 필요한 방사능중앙 공기중역학직경(Activity Median Aerodynamic Diameter)값으로 변환하였다. 또한 원전 정지 10년 후 비방사능 값을 ORIGEN code로 계산하였으며, 최종적으로 핵종별 예탁유효선량을 IMBA 프로그램을 이용하여 계산하였다. 핵종별 예탁유효선량값을 비교한 결과 152Eu에 의한 최대 예탁유효선량은 전체 선량값의 83.09%를 차지하고, ¹⁵²Eu를 포함한 상위 5개 원소(¹⁵²Eu, ¹⁵⁴Eu, ⁶⁰Co, ²³⁹Pu, ⁵⁵Fe)의 경우 최대 99.63%를 차지함을 확인하였다. 따라서 원전 해체 전 콘크리트의 구성 원소 중 상위 5개 주요 원소 측정을 먼저 시행한다면 더 빠르고 원활한 방사능 피폭관리 및 해체 작업 안전성 평가가 가능할 것으로 판단된다.

Purpose Recently, there has been increasing demands for clinical departments at Asan Medical center in Seoul. They want to see the results of lab tests about blood samples as soon as possible and to be reported to them on the day. As the main contents of the survey, we explained the goodness of Asan medical center's in vitro and the points to be improved. Based on this, it became an opportunity to create a positive image of In vitro laboratory. In addition, we could identify their specific requirements through the surveys. Materials and Methods In September 2016, a total of 14 questionnaire surveys were conducted for 49 clinical departments and outpatient nurses at Asan Medical center in Seoul. The survey consists of description questions to be able to express the intention of the individual and the questions made on the Likert 4 point scale. The main contents of 14 questions are composed of goodness of In Vitro laboratory and points to be improved. Results 62% answered that the best service in In Vitro laboratory was "good accuracy and reproducibility". On the other hand, as an inconvenience when requesting blood tests, 73% pointed out that "the result report time was long", which was recognized as a part to be improved. There are many contents that "The result of all tests is reported within 2 hours" on the day of the examination. In the question - 'Are there some examination results which do not coincide well with clinical observations?', 55 of 56 people answered "no". Above all, the majority answered that waiting for re-examination results is too long. This problem must be causing discomfort to the patients. Conclusion In order to improve these problems, the first thing is to increase the number of blood tests by using the current personnel, equipments and reagents to the fullest by item in Asan Medical Center's Nuclear medicine in vitro part. Secondly, in case of re-examinations, we use the "AMIS message" to show other clinical departments the reporting time. This methode improves the efficiency of work with nurses and increases satisfaction of custom service. Thirdly, the correlation was evaluated by selecting the test species that can be carried out by the shortening method. Currently, C-peptide and insulin are implemented in the reaction process to shorten 2 hours into 1 hour. Finally, we are considering purchasing new equipments for quick test results.

Statement of problem : The use of mouthguard is important as the leisure life is popular today. Purpose: The purpose of this study is to investigate the effect of a mouthguard on stress distribution in teeth, maxilla and mandible for maxilla impact. Material and methods: The 3-dimensional finite element model was based on a CT scan film of an average korean adult when the subject is using a customized mouthguard which was made with the Signature Mouthguard system of Dreve. The load was applied to the upper central incisor cervical area parellel impact force for 0.1sec(L1). The Von-mises stress analysis with a mouthguard and without a mouthguard was compared. Results: The results of this study were as follows: 1. Without the mouthguard, stress was concentrated on teeth and alveolar bone in all load conditions. 2. With the mouthguard. maximum stress value was decreased and stress was dispersed in all load conditions. 3. Stress extinction with the mouthguard was faster than without the mouthguard in all load conditions. Conclusion: We acknowledged that the mouthguard has a stress buffer effect as the maximum stress value was decreased and stress was dispersed when impact force was applied.

Reaction characteristics and kinetics of a oxygen carrier (OCN717-R1SU) for chemical looping combustion (CLC) have been investigated using TGA by changing gas concentration (10-30 vol.% $CH_4$) and reaction temperature ($825-900^{\circ}C$). Reaction rate of OCN717-R1SU increased as temperature increased and it was found that reaction is delayed at the initial reaction regime. Johnson-Mehl-Avrami (JMA) model was adopted to explain the reaction phenomenon. The activation energy (E) determined by JMA model in reduction reaction of OCN717-R1SU is $151.7{\pm}2.03kJ/mol$ and pre-exponential factor and JMA exponent were also obtained. The parameters calculated in this study will be applied in design of the reactor and operation conditions for CLC process.
