국내 정치 역학과 수니-시아파 담론갈등

서정민(Seo, Jeongmin) 한국이슬람학회 2020 한국이슬람학회논총 Vol.30 No.1

Sectarian conflicts in the Middle East has become more acute recently. On the basis of a instrumentalist and constructivist and institutional approach, this study attempted to comparison between domestic and regional variables to understand of which variable has been more associated with sectarianism. Among the most important regional political transformers in the 21st century, this paper dealt with the Iraq War, the Arab Spring and Syrian civil war, and the conclusion of the Iran nuclear deal. As for the domestic political variable, the appointment of Saudi Arabia s crown prince was selected as the most important political transformer in Saudi political stability or regime survival. To compare the four domestic and regional transformers, frequencies of news articles containing all three search terms - Shia, Iran and Saudi Arabia - were quantitatively measured via Google News. A time series analysis applied to the irregular variation of the significant political variables confirms the hypothesis of the study that domestic political stability and regime survival have a more significant causal relationship with the Sunni-Shiite conflict than the regional political variables.

This study aims to look at the newly launched Biden administration's policy toward Iran. This paper assumes that the Biden administration will advocate for the traditional approach of past Democrats to restore lost American leadership. Based on this, this thesis is based on the hypothesis that the Biden administration's foreign policy shift will be reflected in the Iran nuclear deal. To test this hypothesis, this study compares and analyzes the representative foreign policy speeches of President Trump and President Biden and the first congressional speeches. The KH Coder program will be used to measure the frequency of nouns related to the Middle East and Iran in the speeches of the two presidents. In addition, by analyzing the co-occurrence of words of related key-words, this research would show how the policies and approaches to Iran between the two presidents have been changed.

서정민(Jeongmin Seo) 한국이슬람학회 2023 한국이슬람학회논총 Vol.33 No.1

In coping with the energy crisis caused by climate change and the Ukraine crisis, decarbonization policies have now become a global issue. Korea and MENA countries are also establishing long-term renewable energy green transformation strategies to prepare for future crises. In this regard, it is important to select major parnter countres in the region to strengthen cooperation on the green energy industire. Thus, this research first conducted HHI index studies between Korean and MENA countries to check the closenese of relations. And on the basis of this, a survey was conducted on experts in related fields and the results were examined by analytical hierarchical process (AHP) method based on the relationship with Korea and the influence of trading partners.

국내 폭력적 극단주의 위험 요인 분석

서정민(Seo, Jeongmin) 한국이슬람학회 2016 한국이슬람학회논총 Vol.26 No.1

The media strategies of Islamic State’s propaganda has produced high-definition depictions of the most abhorrent brutality on an industrial scale, ensuring that the IS threat is digitalized and brought firmly into different continents. In response to this phenomenon, various countries have applied a strategy of so-called ‘countering violent extremism.’ Violent extremism can be defined as an ideology or trend which supports or commits ideologically-motivated violence to further political goals. The threat of violent extremism is neither constrained by international borders nor limited to any single ideology. Increasingly sophisticated use of the Internet, social media, and information technology by violent extremists adds an additional layer of complexity. Korea has also faced the threat of Islamic State which utilizes a remarkable media strategy. Thus, this research analyzed what factors can contribute to the emergence of violent extremism. In addition, this study evaluated how well Korean youths perceive violent extremism through a survey analysis. The survey was conducted with a sample group of high-school students on the basis of self-administered questionnaire.

이슬람국가(IS)와 알-카에다의 이념적 그리고 전략적 차이

서정민(Seo, Jeongmin) 한국이슬람학회 2015 한국이슬람학회논총 Vol.25 No.2

The ‘establishment’ of Khalifa system by Islamic State (IS) will generate long-term instability in the Middle East. IS is an Sunni extremist organization which has a clear difference with the conventional Jihadist groups like al-Qaeda. IS and other Islamist groups have a similar ultimate goal of building an Islamic state, but they have different strategies and methodologies. The major targets of Osama bin Laden's al-Qaeda is ‘far enemy,’ i.e., the West led by the US and Israel, IS has prioritize ‘near enemy’ rather than 'far enemy’ cleansing the Muslim community. While Al-Qaeda seeks a ‘defensive jihad’ to protect the Islamic world from the threat posed the West, IS has combined the ‘defensive’ with ‘offensive jihad.’ IS has resorted to a strategy of building Islamic state to remove non-Islamic elements in the Middle East. This study explores how much ideology and strategy between al-Qaeda and IS are different. Despite the fact that the two radical Islamist organizations have utilized the religion of Islam to justify their activities and atrocities, this research assumes that IS, which declared the establishment of Khalifa state, has more assertively put the emphasis on its territorial domination and governance than al-Qaeda did. In order to demonstrate the ideological and strategic difference between the two organizaton, this study analyzed the speeches made by the main leaders of the two groups, Abu Bakr al-Baghdadi and Osama bin Laden. The texts in the speeches of the two leaders were analyzed through the KH Coder. The result of the analysis showed considerable differences in word usage and co-occurrence networks.

사회정체성과 취약계층의 극단주의 자생환경

서정민(Jeongmin Seo) 한국이슬람학회 2018 한국이슬람학회논총 Vol.28 No.1

Extremism is mostly used in a political or religious sense to refer to an ideology that is considered to be far outside the (acceptable) mainstream attitudes of society. Extremism is a complex phenomenon, although its complexity is often hard to see. Most simply, it can be defined as activities (beliefs, attitudes, feelings, actions, strategies) of a character far removed from the ordinary. In conflict settings it manifests as a severe form of conflict engagement. The threat of extremism is neither constrained by international borders nor limited to any single ideology. Increasingly sophisticated use of the Internet, social media, and information technology by extremists adds an additional layer of complexity. Extremism is very difficult to deal with as it emerges from diverse political, social, economic, and cultural reasons. This study hypothesizes that social identity crisis in South Korea may contribute to emergence of homegrown extremism. Thus, this research analyzed whether five main vulnerable social groups can be influenced by extremism. Categorizing such five groups in South Korea as extremist internet communities, multi-cultural families, ill-treated foreign workers, religious extremists, and school maladjusted students, this study conducted surveys with them. The interview results show that the vulnerable social groups with social identity problems are likely to support or sympathizes extremism.

방사선 치료에서 일정한 호흡주기의 유지가 필요한 흉부 및 복부를 치료할 때 환자의 자세와 belly board device의 사용 여부에 따라 다르게 나타나는 호흡신호의 차이를 통계적으로 분석하여 임상적용에 관한 유용성을 검정하였다. 호흡주기유지는 supine 자세에서 비교적 양호하게 나타났으며, prone 자세에서 호흡주기 유지가 양호하지 않은 경우에 belly board를 적용하여 85%가 유의하게 다른 패턴의 호흡주기를 보였고, 57%는 호흡주기 유지가 양호하게 변화한 것으로 나타났다. 각 피험자의 비만도와 체중에 따른 호흡주기유지 안정성의 차이는 보이지 않았으며, 안정성의 상대적 비교지수로 분석한 시간의 흐름에 따른 호흡의 안정성 유지는 supine 자세에서 비교적 안정적이었으며, 호흡주기 유지의 검정통계결과와 일치하였다(p=0.044, kappa=0.607). 흉부 및 복부 심지어 골반의 방사선치료에서도 호흡에 의한 환자의 움직임은 중요한 고려사항 중 하나이다. 환자의 치료부위와 target의 위치, 예상되는 plan의 beam arrangement에 따라, 환자의 자세 및 device의 여부가 결정되지만, 본 연구와 같이 호흡신호의 통계적 분석과 이의 적용을 통해, 호흡유지에 최적의 자세, belly board와 같은 device 사용여부를 결정하여, 호흡주기의 유지 및 호흡의 안정도 유지에 기여할 수 있을 것으로 사료된다. This study statistically analyzed the difference of the stability of maintaining a respiratory period shown according to position and use of a device to search the tendency and usefulness of a device. The supine position showed better maintaining respiratory cycles than the prone position. The 85% of subjects who showed bad maintenance pattern of a respiratory cycle were significantly different pattern with using belly board. It could be said that there was a significant correlation between the maintenance of a respiratory cycle and relative index of respirational stability(p=0.044, kappa=0.607). The movement due to respiration was one of important considerations in the radiation therapy on chest, abdomen, and even pelvis. This study could contribute to the high quality radiation therapy by statistic analysis of respiratory signals and its application.

사지의 방사선치료에 사용되는 쌀 볼루스의 품종에 따른 방사선량분포의 민감도 연구

서정민(Jeongmin Seo) 한국방사선학회 2020 한국방사선학회 논문지 Vol.14 No.6

사지부위에 많이 발생하는 연부조직육종의 방사선치료에 사용하는 쌀을 이용한 볼루스의 적용에서 쌀의 품종에 따른 형태적 차이에 따라 달라지는 방사선량분포의 차이가 발생하는지를 알기 위하여 일반적인 국산 쌀과 낱알의 크기가 작은 태국산 쌀을 각각 적용한 쌀 볼루스의 선량분포 민감도를 비교하였다. 쌀 볼루스를 적용하지 않는 팬텀, 국산 쌀을 사용한 쌀 볼루스를 적용한 팬텀, 태국산 쌀을 사용한 쌀 볼루스를 적용한 팬텀에 동일한 방사선치료계획을 수립하고 동일한 지점 12곳에 대한 선량을 비교하였다. 등중심점에 대하여 100 cGy를 처방하였으며, 낱알의 크기가 작고 긴 태국산 쌀을 이용한 쌀볼루스에서 평균 103.57±1.98 cGy, 국산 쌀 볼루스에서 평균 104.27±2.12 cGy, 볼루스가 없는 팬텀에서 104.99±6.40 cGy의 선량분포를 보였다. Wilcoxon’s Signed Rank test에서 태국산 쌀 볼루스와 국산 쌀 볼루스의 선량분포가 유의한 차이를 보였다(p=.011). 낱알의 크기가 작고 긴 태국산 쌀을 이용한 볼루스에서 더 균등한 선량분포를 보임을 확인하였으며 임상에서 이를 고려하면 더 양질의 의료서비스를 제공할 수 있을 것이다. To investigate the radiation dose sensitivity in extremity radiatioin therapy depending on rice cultivar which have different size and shape of grains, plan results are compared that used rice bolus Korean and Thai rice. Phantoms that are each no bolus, Korean rice bolus, Thai rice bolus were used and prescribed 100 cGy to isocenter and checked the point dose of 12 points of interest of each phantoms. The meane dose are 103.57±1.98 cGy in Thai rice bolus using, 104.27±2.12 cGy in Korean rice bolus and 104.99±6.40 cGy in phantom without bolus. Dose distribution of Thai and Korean rice bolus differed significantly in Wilcoxon s Signed Rank test (p=.011). It has been confirmed that that the bolus using Thai rice, which has a small grain size, shows a more even dose distribution.

국어의 경음화현상과 불투명성 - OT-CC를 중심으로 : 국어의 경음화현상과 불투명성

서정민(Seo Jeongmin),조학행(Jo Hakhaeng) 한국언어문학회 2006 한국언어문학 Vol.59 No.-

The purpose of this paper is to investigate the opacity in post-liquid tensification of Korean verbal inflection. For this, after classifying the tensification phenomena in Korean, we will present the opacity problem. Following that, we will analyze the opacity in post-liquid tensification of Korean verbal inflection within the framework of McCarthy(2006a)’s recent proposal, Optimality Theory with Candidate Chains (OT-CC, henceforth), which incorporates inter-candidate derivational information with PREC (edence) constraints(A, B). This paper is organized as follows. Section Ⅰ provides introductory remark about this paper. Section Ⅱ provides an introduction of OT-CC. In Section Ⅲ, we will analyze the opacity in post-liquid tensification of Korean verbal inflection resulting from rule overapplication within the framework of OT-CC. Section Ⅳ is a concluding summary.
