중국의 핵개발에 대한 미국의 비확산 정책: 북핵(北核) 문제에 주는 함의
권태오 한국국방연구원 2020 국방정책연구 Vol.35 No.4
This paper intends infer what the US will do with North Korea who already succeeded in possessing nuclear weapons from the past China's nuclear development case. During the 1950s to 1960s, when China was developing nuclear weapons, US took various counter-measures to block China’s nuclear development. Not only did US consider international efforts to resolve peacefully by signing international agreements for non-proliferation, but also US considered military attack in cooperation with the Soviet Union against China’s effort for weaponization. This was very similar to the policy US exercised against North Korea's nuclear development. In the end, however, all Washington’s policies failed. Recalling this lessons, This paper will suggest South Korea need to prepare aggressive policies for the worst case of US possible policy toward North Korea denuclearization.
Continentalic Acid from Aralia continentalis induces Growth Inhibition and Apoptosis in HepG2 Cells
권태오,정승일,권지웅,김윤철,장선일 대한약학회 2008 Archives of Pharmacal Research Vol.31 No.9
In this study, we investigated the effects of continentalic acid (CA, (-)-pimara-8(14),15-diene-19-oic acid), a diterpenic acid, isolated from Aralia continentalis, on the proliferation and apoptosis induction of HepG2 cells. In 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay, the inhibitory effect became gradually stronger with the passage of time, 24, 48 and 72 h after treatment with CA, and the most significant effect was observed at 72 h. CA treatment for 72 h induced DNA fragmentation in a dose-dependant manner. Furthermore, flow cytometric analysis of HepG2 cells exposed to CA showed that apoptotic cells increased in a dose-dependent manner. The induction of apoptosis in HepG2 cells by CA was mediated through the activation of caspase-3, Bak, and Bax, and then through the cleavage of peroxisome proliferator-activated receptor (PARP) and the down-regulation of Bcl-2. These results demonstrate that CA efficiently induces apoptosis and is a good candidate for further evaluation as an effective chemotherapeutic agent.
중국의 핵실험 과정에서 나타난 미국의 대응이 북핵 문제에 주는 함의
권태오 서울사이버대학교 미래사회전략연구소 2018 미래사회 Vol.9 No.1
중국은 1964년 10월 1차 핵실험을 실시하여 다섯 번째 핵클럽 국가가 되었다. 당시 미국은 중국이 핵을 개발하는 것을 쉽게 차단할 수 있을 것으로 오판하였다. 그러나 경제제재, 국제 조약 형성을 통한 저지, 심지어 군사적 타격까지 검토하였으나 모두가 실패하였다. 마치 1990년대 이후 북한의 핵 개발을 두고 제재와 대화, 협의, 군사력 현시 등을 구사하는 미국 의 지금 모습과 흡사하다. 결국 장거리 미사일 개발로 미국 본토를 겨냥하는 위협이 당장 없 다면 초보적인 핵을 보유하는 것을 용인하는 결론을 내릴 수도 있다는 우려를 자아내고 있 다. 그런데 미국이 중국의 핵개발을 용인하는 과정에서 대만은 UN에서의 지위를 모두 중국 에게 넘겨줄 수밖에 없었고 대만과 미국과의 상호방위조약도 폐기될 수밖에 없었다. 핵을 가진 북한을 당시의 중국으로 가정하여 미래를 예측해 본다면 한국이 대만과 같은 상황이 될 수 있다는 부정적 예측이 나올 수 있다. 본고에서는 중국의 핵개발 배경과 과정을 살펴보 고 이를 중지시키기 위한 미국의 노력이 어떤 것이었으며 과연 효과적이었나를 분석해 보고 자 한다. 아울러 대한민국이 취해야 할 정책은 어떠해야 하는가를 제시하고자 한다. In October 1964, the China conducted the 1st nuclear test and became the 5th Atomic-Club country. At that time, the United States misjudged that it could easily block the China's development of nuclear weapons. However, those options including of economic sanctions, blocking through the coordination of international treaties, and even military strikes were considered, but all failed. It is similar to the present conditions of the United States, which has been using sanctions, dialogue, consultation, and military power for the north Korea's nuclear development since the 1990s. There is some worries that long-range missile development could lead to the conclusion that if there is no immediate threat to the US mainland, then it would be permissible to have rudimentary nuclear weapons, In the process of the US acceptance of the China's nuclear development, Taiwan was forced to hand over its position in the United Nations to the People's Republic of China, and mutual defense treaties between Taiwan and the US were forced to be abolished. If North Korea, which also has nuclear weapons, is substituted with China, and US would take similar steps it took in the past there can be a dark prospect that the ROK's situation can be the same as that of Taiwan. This article examines the background and process of the nuclear development of the China and what US efforts to stop it and how it was effective. In addition, I would like to suggest what kind of policies ROK and US should take in future.

산채막(山菜莫)(Cornus officinalis Sieb. et Zucc. )의 조직배양(組織培養)을 위한 기초적(基礎的) 연구(硏究)로서 체배양(諦培養)에 미치는 배지(培地), 생장조절제(生長調節劑), 저온(低溫) 전처리(前處理), 배양온도(培養溫度) 및 광(光)의 영향(影響)을 검토(檢討)한 결과(結果)는 다음과 같다. 1. 캘러스 형성율(形成率)은 MS배지(培地)보다 WPM배지(培地)에서 좋은 반응(反應)을 보였으며, Img/L NAA를 첨가(添加)한 WPM배지(培地)에서 54%로 가장 높았고, 캘러스 생장(生長)은 2mg/L NAA를 첨가(添加)한 MS배지(培地)에서 좋았다. 2. 약(約)의 배양온도(培養溫度) 및 광(光)의 영향(影響)은 25℃, 16시간 명배양(明培養)이 62%의 가장 높은 캘러스 형성율(形成率)을 보였다. 3. 캘러스 형성(形成)에 미치는 약(約)의 저온(低溫) 전처리(前處理) 효과(效果)는 4℃, 36시간 처리(處理)에서 19.5%로 가장 높았다. 4. 기관분화(器官分化)를 위한 적정배지(適正培地)로는 0. 5mg/L 2, 4-D와 1mg/L kinetin을 첨가(添加)한 MS배지가 녹점형성(綠點形成) 및 뿌리분화를 촉진(促進)하였다. 5. 캘러스 양변화(楊變化) 방지(防止)를 위하여는 3-5mg/L ABA 와 5mg/L AgNO3의 첨가(添加)가 효과적이었으며, 캘러스 활력(活力)이 높아 녹점형성(綠點形成)을 촉진(促進)하였다. The effects of media, growth regulators, low-temperature treatments, culture temperature and light were investigated to improve the callus induction and growth in the anther culture of Comus officinalis Sieb. et Zucco. The frequency of callus induction was more effective on WPM medium than MS medium, and it was highest as 54% in WPM medium supplemented with Img/L NAA. Callus growth was stimulated on MS medium supplemented with 2mg/L NAA. Effect of temperature and light on the callus induction and growth was highest as 62% in the treatment for 16/8 hrs. (light/dark) at 25℃ Effect of low - temperature treatment on callus induction was highest as 19. 5% in the treatment for 36 hrs. at 4℃. For organization, green cells and rootings were promoted on MS medium supplemented with O. 5mg/L 2,4-D and 1 mg/L kinetin. The prevention of callus browning was effective on the medium containing 3~5mg/L ABA or 5mg/L AgNO3. The supplement of ABA or AgNO3,were maintained callus activity for 4-5 weeks and they were promoted the development of green cells.
