The purpose of this study is to analyze the Latin American research trends in Korea through methodological diversity. In other words, based on the leading research related to this research topic, this paper maintains the methodological differentiation of existing qualitative or basic statistics by conducting machine learning-based data analysis. To this end, first, this paper collects data through the Research Information Sharing Service (RISS). The subject and scope of this study is to set to 'Latin America (Jungnammi)' as the title of the paper and and 'Latin America' in the keyword of the abstract, and subsequently are collected according to the definition of crawling in the R software program. Secondly, the data extracted by the definition of crawling is preprocessed for topic modeling, association analysis, and word cloud analysis, which are the research methods of this paper, and then the data is processed with algorithms suitable for each analysis. Third, the unit of analysis of this study is the classification by generation (years). Therefore, based on the results calculated through the analysis of the three big data, the data classified in this way examines trends in Latin American research in Korea. The main topic of research in Latin America, which has been steadily conducted since 1968, is economy (trade)-related topics. and Also other research themes have been studied based on Latin American region-related or global issue.

이태혁,이영준,박경태,정하국,이종현 대한금속·재료학회 2015 METALS AND MATERIALS International Vol.21 No.2

In this work, an Al/Cu composite was fabricated using repeated hydrostatic extrusions with a semi-die angleof 45° at a temperature of 200°C. During the repeated hydrostatic extrusion process, an intermetallic layerof 1 m was generated at the Al/Cu interface. The intermetallic reinforcement layer formation was studied viafield emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, and transmission electronmicroscopy. The reinforcement layers consisted of Al2Cu and Al4Cu9 phases. The thermal conductivityand coefficient of thermal expansion of the Al/Cu composites were determined via laser flash analyzer andthermal mechanical analyzer. The thermal conductivities in the longitudinal direction and cross direction were267.8 W/mK and 209.9 W/mK at room temperature, respectively. The coefficient of thermal expansion at temperaturesbetween room temperature and 450°C was 18.3 m/m°C. The ultimate tensile strength of the Al/Cucomposite is 102.8 MPa. The anisotropic physical properties of the prepared composite were mainly a resultof the unique directional microstructure formed during the repeated extrusion process.

The purpose of this paper is to analyze the significance of migration patterns by identifying trends in migration from Haiti since 2010. In particular, the driving force that differentiates migration trends is the perspective that these trends are shaped by changes in destination countries, rather than issues within Haiti, the country of origin. The unstable internal factors within Haiti, the country of origin, are constants rather than explanatory variables. In other words, multifaceted inequality and vulnerability to climate change, especially due to social disasters, existed before and after 2010. Paradoxically, Haiti’s deviation from ‘normalization,’ where instability becomes the norm, is a natural outcome. As a result, the pattern of international emigration from Haiti has become established. However, a new trend is emerging from the Global North, including the United States or Francophone countries, to the Global South, including Brazil. This study examines why Haitian migrants have increasingly chosen to immigrate to South America, with a specific focus on Brazil, since 2010. The analysis considers factors such as geopolitics, the economy, immigration policies, and cultural assimilation in the receiving country.

에콰도르의‘이중성(dual identity)’: 중국의 등장과 에콰도르 아마존지역 개발의 정치경제적 역설(paradox)

이태혁 서울대학교 라틴아메리카연구소 2016 이베로아메리카硏究 Vol.27 No.1

This paper seeks to increase the understanding of Amazonian development under the current leftist government in Ecuador, in the context of the discourse in (international) political economy of development. The political economy of development repeats ‘change and continuity’. Particularly, the beginning of this discourse works together with the colonial period(Michael 2012). Latin American countries, including Ecuador, commonly embedded the nature of natural resource-related dependent development. In this historically embedded structural context, the 21st century leftist governments emerged, proclaiming the economic redistribution and political economic inclusiveness for those who were excluded under neo-liberalism. In short, these leftist governments attempt to realize the post-neoliberal by framing the new extractivism. However, it has been identified that Ecuador faces a dual identity concerning its oil extraction policy. In particular, Ecuador declared the Yasuni ITT Initiative in the international community in 2007, subsequently, the current leftist government rejected this approach in 2013. The government then chose China as a ‘exit’ strategy. This study argues that the Equatorial political economy of development has displayed characteristics of dependency, through its partnership with the emergence of China, and this indicates the aspect of paradox of the Equatorial political economy. Key words New Extractivism 본 논문은 개발의 (국제)정치경제의 담론을 살펴보며, 에콰도르 현 좌파 정부상황하의 아마존지역 개발에 대한 이해를 높이기 위한 연구이다. 개발의 정치경제는 ‘변화와 지속성(change and continuity)’의 반복이다. 특히, 이 담론의 시작은 식민지 시대와 궤를 같이 한다(Michael 2012). 에콰도르 등 중남미 국가들이 공통적으로 지하자원과 관련된 개발의 종속적인단면이 내재화 되어있고, 이에 대해 21세기 좌파 정부 등장하 경제적 재분배와 신자유주의 하배제된 이들(예, 원주민 등 소수자)의 정치경제적 포용(inclusiveness)을 천명했다. 즉, 신채굴주의(new extractivism) 형태로 포스트 신자유주의(post-neoliberalism) 모습을 구현하고자 한것이다. 하지만 에콰도르의 꼬레아 정부의 석유채굴 정책과정을 통해 이중적(dual identity)인모습을 확인하게 된다. 특히 2007년 에콰도르 꼬레아 정부가 전략적으로 Yasuni ITT Initiative 를 국제사회에 공언했지만, 이내 2013년 현 정부는 이 전략적 ‘카드’를 내려 놓게된다. 그리고그 ‘출구’ 전략으로 중국을 선택한다. 본 연구는 에콰도르의 개발의 정치경제적 정책이 중국의등장으로 종속적인 면이 지속된다고 주장하고 있으며, 이는 현 에콰도르 정부의 정치경제적 역설의 한 단면을 보여준다.

워드 클라우드(Word Cloud) 기법을 이용한 K-콘텐츠 관련 기사(2011-2022) 분석과 함의 : 중남미를 중심으로

이태혁 한국국회학회 2022 한국과 세계 Vol.4 No.5

The Korean Wave, which has expanded from the ‘mainstream’ in East Asia to the global dimension, is divided into stages of development according to period, region, and content. According to the classification framework, which divided the development stages of Hallyu into four phases (including the New Hallyu), non-Asian regions, including Latin America, which is the target region of this study are all belong to the second phase of the Korean Wave after the late 2000s. The period after 2020, which is also referred to as the New Hallyu(K-culture), the characteristic of this period is marked with the 'K(S)' mark such as K-drama, which is the representative content of the 1st period of the Korean Wave, K-pop, K-movie, K-food, and K-game. It has evolved into a total brand with a variety of contents. In this vein, this paper aims to examine the Korean Wave phenomenon in Latin America through methodological differentiation in existing Hallyu-related studies. Particularly, this paper is about whether the Korean Wave in Latin America conforms to the existing development stage of the Korean Wave? To acquire the answer to this inquiry, this analyzes big data-related to K-contents employing the word cloud technique using the R program. As a result of frequency analysis through text mining, K-pop in 2010, the beginning of the Korean Wave in Latin America, was the main 'power', and 10 years later, K-pop still has a large proportion. Therefore, it is somewhat insufficient to see that Latin America has grown and expanded significantly from the early stage of the Korean Wave. In other words, the Korean Wave in Latin America can be seen as the spread and fixation of music genres-related to K-pop rather than the diversification of K-contents. 동아시아의 ‘본류’에서 글로벌 차원으로 ‘지류’가 확장된 한류(Korean Wave)는 시기별, 권역별, 그리고 내용에 따라 발전 단계를 구분할 수 있다. 한류의 발전 단계를 모두 4기(신한류 포함)로 구분한 유형 분류 틀에 따르면 본 연구의 대상 지역인 중남미권을 위시로 하는 非아시아권은 모두 2000년대 후반 이후인 한류 2기에 속한다. 특히, 2020년 이후를 신한류(K-culture)로 지칭되며 이 4기의 특징은 한류의 1기의 대표 콘텐츠인 K-drama를 필두로, K-pop, K-movie, K-food, K-game 등 ‘K(S)’ 마크를 장착한 다양한 콘텐츠를 가지고 있는 토탈 브랜드(Total Brand) 형태로 진화했다. 기존의 연구물을 바탕으로 본고는 기존의 한류관련 연구에 방법론적 차별화를 통해 對 중남미 한류 현상의 고찰을 목적으로 한다. 특히 본고는 중남미지역의 한류는 기존의 한류 발전 단계에 부합하는가? 에 대한 연구 질문을 던지며, R 프로그램을 활용하여 워드 클라우드(Word Cloud) 기법을 이용한 K-콘텐츠 관련 빅데이터 분석을 한다. 텍스트 마이닝을 통한 빈도분석에 따르면 중남미 한류 태동기인 2010년 K-pop이 주요 ‘동력’이었으며 10년이 지난 현재도 K-pop의 비중이 여전히 높다는 결과가 도출되었다. 따라서, 중남미지역은 한류 태동기의 양상에서 크게 성장 및 확대되었다고 보기에는 다소 미흡하다. 즉 중남미지역의 한류는 K-contents의 다양화이기 보다는 K-pop과 관련된 음악 장르의 확산과 고착화의 양상으로 볼 수 있다.

기후변화와 강제이주 : 온두라스를 중심으로

이태혁 한국국회학회 2023 한국과 세계 Vol.5 No.3

In the global context, there is a growing recognition of the multidimensional changes caused by climate change, leading to discussions and research on the link between climate change and forced migration. One notable example is the migratory procession of Honduras in Northern Central America, often referred to as the 'Caravan,' While climate change affects everyone, its impacts are not distributed equally. There are certain groups that are more vulnerable to its effects, particularly the poor who face greater exposure and damage from climate crises. This phenomenon highlights the climate inequality that exists. This article argues that when structural inequalities such as poverty intersect with climate change, it leads to a significant number of climate refugees. The degree of vulnerability to climate change is confirmed by examining the 'double' characteristics of Honduras' climate at the geographical level. The agricultural- oriented industrial structure of Honduras, particularly in the dry corridor, is explored to further understand the degree of vulnerability to climate change. The dynamics of forced migration are examined in relation to these factors. Finally, the article concludes by reviewing explanatory variables of climate change for mass migration from Honduras, discussing the limitations of the paper, and suggesting areas for further research. 기후변화와 (강제)이주는 어떠한 상관관계가 있을까? 전 지구적 맥락에서 기후변화에 따른 다층적 차원의 ‘변화’가 감지되고 있는 가운데 기후변화와 강제이주성에 대한 논의 그리고 이에 따른 연구가 진행되고 있다. 북중미의 온두라스의 가칭 ‘카라반(Caravan)’ 이주 행렬의 현상은 강제이주의 성격을 띠며, 이는 기후변화에 취약한 온두라스의 지리적 특성과 아울러 가난한 사람들에게 더욱 가혹한 기후위기 특징이 반영된 것이다. 기후변화는 평등하다. 하지만, 기후변화의 영향은 평등하지 않다. 즉 기후변화 영향에 취약한계층이 있다. 빈곤할수록 기후위기 노출에 취약하며 따라서 그 피해 또한 크다. 기후불평등이다. 이러한 관점에서 본고는 빈곤 등의 사회경제의 구조적 불평등이 기후변화와 만나면 기후난민이 대량 발생한다고 주장한다. 이에, 본고는 먼저 기후변화와 강제이주간의 논의에 대한 선행연구를 통해 본 연구의 분석적 틀과 연구의 목적을 피력한다. 그리고 온두라스의 기후의 ‘이중적’ 특성을 지리적 차원에서 고찰함으로 기후변화의 취약성 정도를 확인한다. 다음으로 온두라스의 농업에 기댄 산업구조 특히 건조회랑(dry corridor)에서의 농업중심의 경제 산업 구조를 살펴봄으로 기후변화의 취약정도를 파악한다. 그리고 이에 따른 강제이주의 역동성을 고찰한다. 끝으로 온두라스발 대량 이주현상에 대한 기후변화 설명변수를 재고찰하며 본고의 한계 제시 및 후속연구를 제안하며 마무리 한다.

Is Initiative for South American Regional Integration(IIRSA) an “inclusive” development? IIRSA is an infrastructure-oriented projects which primarily aim to extend for Social Overhead Capital(SOC) while the leftist governments in South America seized the power at the beginning of 21st century. In this context, this paper seeks to find as to whether IIRSA is de facto coupled with the notion of inclusive development, which mainly cares for the interests of multi-faceted actors. Thus, to solve this puzzle, the fieldwork has been implemented. The fieldwork took place on a tri-border state of Brazil, Peru and Bolivia where Integration Bridge constructed, in the line of Bi-Oceanic highway. Particularly, this paper is interested in finding out to see whether IIRSA, which is coupled with the emergence of leftist governments, remains as a rhetoric or conducted de facto to carry out the inclusiveness. The research methodology employed as a mixed method by qualitative and quantitative, so as to conduct a fieldwork research. Assis Brazil, in which the Acrean Integration Bridge has been constructed and located in a border city of Acrean state, has two interesting historical facts. One of them is rubber tree and latex and the other, the cattle's occupation in Amazon area. Subsequently, this research understood historically embedded societal structure, which contains the notion of bifurcated aspects as patron vs semi-slavery, by way of these two interesting factors. Finally, this research found that because of this embedded societal structure societal-economic ‘path dependence’ played a key role in limiting the nature of inclusive development of IIRSA at the local level.
