What are Technical Hurdles of Verification for North Korea’s Nuclear Program?

최성열,전은주 한국방사성폐기물학회 2022 방사성폐기물학회지 Vol.20 No.1

The denuclearization of North Korea was unpredictable and resulted in radical changes. Despite the skepticism and disappointment surrounding denuclearization, it is important for certain verification technologies to establish what is technically possible or practically impossible, and how reliable these technical means are. This article presents the technical hurdles in nuclear verification by systematically categorizing them into issues of correctness and completeness. Moreover, it addresses the safety and security risks during the denuclearization process, including the radiological impact on humans, environmental effects, and the illegal transfer of material, information, and technologies.

CARE 지침에 따른 2018∼2021년 동의신경정신과학회지 증례 보고의 질 평가

최성열 대한한방신경정신과학회 2022 동의신경정신과학회지 Vol.33 No.2

Objectives: The purpose of this study was to evaluate the quality of reporting for case reports published in Journal of Oriental Neuropsychiatry from year 2018 to 2021 compared with year 2013 to 2017 in order to recommend ways to improve the quality of case reports published in the future. Methods: To evaluate the quality of case reports identified by electronic searching in Oriental medicine Advanced Searching Integrated System (OASIS) and by hand searching from archives on peer review system of Journal of Oriental Neuropsychiatry using CAse REport (CARE) guideline. The researcher assessed the quality of reporting based on the CARE guideline as 'Sufficient', 'Not-Sufficient', ‘Not- Applicable’, and 'Not-Reported' for case reports published from 2018 to 2021 in Journal of Oriental Neuropsychiatry. In addition, it was compared with previous case reports published from 2013 to 2017. Results: Finally, 17 case reports were included for the assessment. General quality of reporting for case reports published from year 2018 to 2021 was improved compared with that of previous case reports published in 2018. The maximum value (46.4%→60.7%, 14.3% increase), the minimum value (22.2%→ 32.1%, 9.9% increase), and the median value (39.3%→50.0%, 10.7% increase) of the report rate evaluated as 'Sufficient' were generally improved. The maximum value (53.6%→50.0%, 3.6% decrease), minimum value (25.9%→21.4%, 4.5% decrease), and median value (35.7%→32.1%, 3.6% decrease) of the report rate evaluated as 'Not-Sufficient', the maximum value of the report rate evaluated as 'Not-reported' (40.7%→25.9%, 14.8% decrease), the minimum value (14.7%→10.7% decrease), and the intermediate value (14.7% decrease) were also generally improved. Four items (8b, 8d, 10c, and 13) were evaluated as 'Not-Reported'. These items seem to be items that need urgent improvement along with 8c, which showed a significant decrease in reporting rate. Conclusions: There are needs to improve the quality of case reports in Journal of Oriental Neuropsychiatry by comparing case reports published from year 2013 to 2017 with case reports published from year 2018 to 2021. To improve the quality of case reporting, sufficient education at the academic level should be provided on thesis preparation methods. It is also necessary to develop a tool for evaluating the quality of case reporting that reflects characteristics of Korean Medicine.

전기 자전거용 토크센서 개발

최성열,전용호,조황,Choi, Seong-Yeol,Jeon, Yong-Ho,Cho, Whang 한국전자통신학회 2011 한국전자통신학회 논문지 Vol.6 No.6

최근 환경오염, 지구 온난화, 화석 연료 고갈 등이 범지구적 문제가 됨에 따라 녹색 에너지 기술 개발이 주목을 받고 있다. 이런 추세에 따라, 자전거가 다양한 스마트 에너지 기술과 결합하여 친환경 근거리 이동수단으로 발전하고 있다. 스마트 자전거 기술과 관련하여 많은 기술이 개발되고 있는데 이중 PAS(Power Assist System)는 사람의 힘과 전기의 힘을 효과적으로 결합하여 배터리로 구동되는 전기 모터를 제어하는 기술이다. 본 논문은 PAS를 구성하는 핵심 기술인 새로운 토크 센서를 제안한다. 이 기술은 기존 기술들과는 달리 자전거 뒤축에 스트레인 게이지를 부착하여 슬립링의 필요성을 없애고 사람에 의해 가해지는 구동축 토크를 측정 할 뿐 아니라, 현재 작동되는 기어의 위치를 근사적으로 추정 가능하게 한다. As environmental pollution, global warming, and exhaustion of fossil fuel become global issue recently, there has been strong research motivation to develop green energy technology. Along the same line of motivation, some research efforts have been put into the development of environment-friendly bicycle equipped with various smart energy technologies to increase the usability of the bicycle as short-distance transportation. Among the technologies related with new generation bicycle, PAS (power assist system) is one of the most important systems that are essential in efficiently integrating human power and the electrical power supplied by electric motor driven by battery. In this paper, a novel torque sensor technology which is core component for PAS is proposed. Unlike existing technologies, strain gauges are attached to rear shaft directly under the hub bearings, which eliminates the requirement of slip-ring, Furthermore, the sensor is able to not only measure the torque transmitted to driving axle by human but also estimate the position of the gear to which the chain is currently engaged.

Epitaxial (Mn0.66Cr0.33)₂As and (Fe0.66Mn0.33)₂As thin films : magnetic and structural properties

최성열,최정용,홍순철,조성래,박현민,박용섭,이규원 한국자기학회 2005 한국자기학회 학술연구발표회 논문개요집 Vol.15 No.1

We grew (Mn_(0.66)Cr_(0.33))₂As and (Fe_(0.66)Mn_(0.33))₂As thin films directly on n-type Si (100) substrate by molecular beam epitaxy (MBE) at the substrate temperature, Ts=300 ℃. The growth was monitored with RHEED (reflection high-energy electron diffraction). We have observed streaky RHEED patterns, indicating the layer-by-layer growth of (Mn_(0.66)Cr_(0.33))₂As and (Fe_(0.66)Mn_(0.33))₂As thin films. We found that the crystal structure of (Mn_(0.66)Cr_(0.33))₂As and (Fe_(0.66)Mn_(0.33))₂As thin films were the tetragonal Mn₂As type with a=3.745 Å and a= 3.70 Å. (Mn_(0.66)Cr_(0.33))₂As thin film shows spin-glass behavior below 130 K, while (Fe_(0.66)Mn_(0.33))As alloy shows ferrimagnetic ordering at around room temperature.

정보기술과 현대시와의 융합에서 추출한 ‘소통과 유희’

최성열 국제문화기술진흥원 2015 The Journal of the Convergence on Culture Technolo Vol.1 No.1

필자는 인문학과 과학의 교차점을 찾아 중첩하는 에너지를 현대시에 관철시키고 용합적 에너지를 도출하여 감히 인간 삶에 도움을 주고자 한다. 그 조그만 일임을 감당하기 위해서 현대적 감각을 가진 현대시로써 정보기술과 결탁하고 인간관계의 상관성 에 합당한 ‘소통과 유희’를 누리고자 한다. 이 말은 곧 즐거운 인생을 살자는 의미다. 특히 유희란 바람직한 인간상을 위시하여 행복한 삶을 살 수 있는 장이라고 여긴다. 여기에는 조건적 매개가 필요한데 그것은 ‘진정한 자유와 참된 행복’이다. 이 두 가지가 선한 양심적 인간성의 특질에서 기인한다면 필자가 주창한 인문학적 영역인 ‘정보기술과 현대시와의 만남’에서 결국 ‘소통과 유희’ 를 도출할 수 있을 것이라고 전망한다. The purpose of this research is to try to enrich human life by applying the convergence energy of humanities and science to modern poetry. “Communication and entertainment,” as modern poetry with modernist aesthetics, must indulge people’s lives, which is simply to live happy lives. Entertainment is especially crucial because it is a method through which people can lead humane and satisfactory lives. The prerequisites for achieving this are true liberty and happiness. If these two prerequisites derive from humanity’s consciousness, “communication and entertainment” can be born from “convergence of information technology and modern poetry,” as the author insisted.

만가닥버섯의 기능성 물질과 품종 선발

최성열 한국버섯학회 2008 한국버섯학회지 Vol.6 No.2

만가닥버섯(Lyopyllum ulmarium)은 주름버섯목 송이 버섯과에 속하는 버섯으로 동남아시아, 유럽, 북미 등에서 발생하는 버섯이다. 우리나라에서는 1980년대부터에 재 배가 시작되었으나, 재배기간이 길어 농가에서 기피하다 최근들어 재배가 시도되고 있다. 본 시험에서는 노루궁뎅 이, 만가닥, 팽이 그리고 검은비늘버섯을 대상으로 항산화 력과 항산화 성분 그리고 tyrosinase 저해활성 및 ACE(angiotensin converting enzyme) 저해활성을 탐색 하여 유용 식용자원으로서의 가치를 평가하고, 만가닥 버 섯 품종의 선발하고자 하였다. 만가닥버섯의 총페놀화합물의 함량은 100g당 506.7mg 이었으며, 총항산화력은 609.2 AEAC(Ascorbic acid Equivalent Antioxidant Capacity)이었다. 만가닥버섯 열 수추출물의 DPPH 라디칼을 이용한 전자공여능은 34.6% , 금속이온의 제거능은 61.6% 이었다. tyrosinase 활성의 억제효과는 17%, angiotensin converting enzyme의 저 해효과는 84%이었다. 만가닥버섯의 품종선발을 위해 15 교배조합에서 808계통의 2핵균주를 얻었으며, 808계통 을 MCM배지에서 12일간 균사생장량을 측정하여 균사생 장량이 높은 120균주를 선발하여 850㎖ PP병에 미송톱 밥+쌀겨(8:2)의 혼합배지에서 자실체를 발생시켜 생육 특성을 조사하였다. 1757계통의 균배양일수는 34.7일이 었으며, 수량은 107.1g으로 가장 우수하였다. 향후 추가 적인 특성의 검토가 필요할 것으로 보인다
