This thesis aims to analyze the political, social, and cultural activities of the Acehnese ethnic group living in Jakarta, Indonesia. Based on analysis, this thesis examines how their ethnicity and national identity have been formed and expressed. For this purpose, this study deals with Taman Iskandar Muda (hereinafter referred to as TIM), a group of Acehnese transmigrants living in Jakarta. The immigration of the Acehnese to Jakarta started in the 1950s and the number of Acehnese people living in Jakarta persently amounts to 100,000. TIM, which was organized by the first generational of immigrants, functions to group Acehnese immigrants of various generations and class. Forum Keprihatinan Untuk Aceh(hereinafter referred to as Forka), an organization designed to solve the political problems of TIM, undertook various activities to maintain the peace of Aceh as the representative of TIM. Through those activities, TIM and Forka were able to confirm the feeling of homogeneity among the Acehnese who were living in their hometown and also strengthen their identity within the organizations. However, the fact that TIM and Forka put their focus on humanitarian activities paradoxically shows the political limitations that they sustain. TIM and Forka take care not to make their humanitarian activities seem as if they intend to openly strengthen their Acehnese identity and deny their Indonesian one. These political characteristics of Forka's identity are commonly found in groups that practice long-distance nationalism, as transmigrants in diaspora circumstances do. In the organization of TIM, there exists the menasah, which is a space where discussions of the ethnicity and the nation are practiced. As it is the space for local exchange, menasah reveals the identity of TIM through educational/social activities and public services. Menasah functions as the public arena where people practice ethnic identity on the basis of national integration. As a minority ethnic group living in Jakarta and its neighborhood, they are accustomed to double and selective political activities, social activities, and cultural practices. In order to adapt themselves to the double circumstance that they are faced with, they should live extemporaneously, and this life may be the fate that minority ethnic and transmigrants should endure.

일반적으로 support vector machine (SVM)은 높은 수준의 분류 정확도를 제공함으로써 다양한 분야의 분류분석에서 널리 사용되고 있다. 그러나 SVM은 최적화 계산식이 이차계획법(quadratic programming)으로 공식화되어 많은 계산 비용이 필요하므로 대용량 자료의 분류분석에는 그 사용이 제한된다. 또한 불균형 자료(imbalanced data)의 분류분석에서는 다수집단에 편향된 분류함수를 추정함으로써 대부분의 자료를 다수집단으로 분류하여 소수집단의 분류 정확도를 현저히 감소시키게 된다. 이러한 문제점들을 해결하기 위하여 본 논문에서는 다수집단을 분할(divide)하고, 소수집단을 과대추출(oversampling)하여 여러 분류함수들을 추정하고 이들을 통합(conquer)하는 DOC-SVM 분류기법을 제안한다. 제안한 DOC-SVM은 분할정복 알고리즘을 다수집단에 적용하여 SVM의 계산 효율을 향상시키고, 과대추출 알고리즘을 소수집단에 적용하여 SVM 분류함수의 편향을 줄이게 된다. 본 논문에서는 모의실험과 실제자료 분석을 통해 제안한 DOC-SVM의 효율적인 성능과 활용 가능성을 확인하였다.

데이터 불균형은 한 분류의 데이터 수가 다른 분류에 비해 지나치게 크거나 작은 현상을 의미하며. 이로 인해 분류 알고리즘을 활용하는 기계학습에서 성능을 저하시키는 주요 요인으로 제기되고 있다. 데이터 불균형 문제 해결을 위해서 소수 분포 데이터를 증폭하는 다양한 오버 샘플링(Over Sampling) 방법들이 제안되고 있다. 이 가운데 SMOTE는 가장 대표적인 방법으로 소수 분포 데이터의 증폭 효과를 극대화하기 위해 데이터에 포함된 잡음을 제거(SMOTE-IPF)하거나, 경계선만을 강화(Borderline SMOTE) 시키는 다양한 방법들이 출현하였다. 이 논문은 소수분류 데이터를 증폭하는 전통적인 SMOTE 방법에서 이상데이터(Anomaly Data)에 대한 처리방법개선을 통해 궁극적으로 분류성능을 높이는 방법을 제안한다. 제안 방법은 실험을 통해 기존 방법에 비해 상대적으로 높은 분류성능을 일관성 있게 제시하였다.

In the absence of the alternative public space of women in Japan, the experience of the "Bongseonhwa" was interpreted as the public domain of Japanese society as a public domain, a confession that focused on gender discrimination in the patriarchal system of Japan, Most of the enemy discourse is. These alienated discourses are the product of the efforts of women in Japan who do not want to forget about the traces and memories that can not be incorporated into the big narrative. It can not be denied that the women in the society of Japan have been excessively excluded and alienated by national ideology and patriarchal ideology. The meaning of presenting them through "Bongsinghwa" is the resistance of the minority, and it is the expression way of reconstructing and strengthening the identity of the women, and it is said to be a space of symbolic meaning. It is further clarified that it is based on a narrative that creates a new life area for coexistence with Japanese society, on the other hand, by constantly searching for the linkage with the motherland, held by women in Japan. As a result, between public social phenomena and private living space, confirmed that it conflicts with repetitive internal contradiction of controlling power and confirmed that complicated and detailed material of women living in Japan who undergo double discrimination What has been expressed over a period is considered to be a resistance expression and a will of expression of reconciliation to coexist with Japanese society. I have attempted to analyze the confessed alienated discourse of "Bongsinghwa" by classifying it as . As a result, it is confirmed that the public social phenomenon and the private life space are confronted with the repetitive internal contradictions of the power of domination, and the expression of the complex and detailed material of the discriminated women in Japan over a long period of time is a resistance to symbiosis with Japanese society And the will of the conversation.

In this paper, I examined the history of Baizu that the Brief History presented. PRC created Baizu as one the 55 ethnic minority nations, as it "nationalized" all the people living within its territorial boundary. And it constructed the narrative of the "ethnic history" of Baizu, while it constructed the grand narrative of the history of the unified, multinational "zhonghua minzu." There are two major problems in the historical narrative of Baizu, thus constructed. First, the genealogy of the ancestors of Baizu constructed by PRC lacks sufficient historical evidence to prove it. Second, the politically-driven ethnic classification project by PRC produced ethnic minority nation, which does not have their own territory and Baizu was one of them. Because of this, the history of Baizu, who historically lived mixed with other ethnic groups together in Yunnan, cannot help but becoming a part of the larger Yunnan history, rather than constituting a history of an ethnic group. Then, what would be a historically sensible way to write a history of ethnic minorities in Yunnan, who have not transformed themselves into a modern nation? What I would like to suggest is, first, to abandon the construction of the history of Baizu as an ethnic group. I also suggest to distinguish Yunnan from China (zhongguo) as a unit of historical writing, and thus to cut the relationship between the Baizu history and the larger history of the unified, multitethnic "zhonghua minzu." The narrative of the Chinese history (history of Zhongguo), which takes the PRC's current territorial boundary as the unit of historical narrative, lacks historical objectivity. Names for historical communities survive, because they have been used by those who have lived in the communities as well as by other historical communities. Members of a certain historical community occupy distinctive historical space and share common historical experience. And their historical experience is mainly informed by political changes that affected the space that the historical community occupies. If one constructs the history of "Yunnan" as a distinctive historical space and community, which could be distinguished from the historical "China" (zhongguo), one may be able to construct the history of the people of Yunnan in its fullest sense.

이 논문은 1994년부터 2002년까지의 중국 상장기업의 데이터를 이용, 기업의 소유구조가 기업성과에 미치는 영향을 분석한 것이다. 특히 이 논문은 중국의 상장기업에 관한 새로운 주식 분류체계를 이용하여 기업 지배주주의 유형, 지배주주의 지분, 소주주들의 지분이 기업성과에 미치는 영향을 분석하고, 관련 가설을 검증하였다. 이 연구를 통해 얻은 결론은 다음과 같다. 주주로서 국가의 존재가 이윤보다는 고용을 유지하는 등 정책적 목표를 우선적으로 추구하거나 혹은 당과 정부의 개입을 초래함으로써 정치비용을 발생시켜 기업성과에 부정적인 영향을 끼칠 것이라는 주장은 적어도 정부지배 기업에게는 적용될 수 있음을 확인하였다. 아울러, 지배주주의 지분이 클수록 지배주주가 경영자에 대한 감시를 강화할 유인이 커지거나 혹은 지배주주가 소주주를 착취(expropriate)할 유인이 줄어 드는 것으로 인해 기업성과에 양의 영향을 미치게 된다는 주장은 민간기업 및 부분적으로는 시장화 국유기업에는 적용될 수 있는 것으로 나타났다. 마지막으로 소주주들은 경영자 감시에 적극적으로 나섬으로써 기업성과에 양의 영향을 미친다는 주장은 시장화 국유기업과 부분적으로는 민간 기업에는 적용될 수 있는 것으로 나타났다.

The purpose of this paper is to make a critique of racial aspects of Caribbean literature more ethical through a constant concern with history and political philosophy. The first step I take for this purpose is a comparative reading of C. L. R. James's view of Toussaint L'Ouverture's position and Frantz Fanon's view of race and class in the historical context of the Caribbean power-relations. In so doing, I examine how Toussaint's and Fanon's wills to negotiation were thwarted in the New World history. To elaborate upon this ethico-political approach, I have recourse to the so-called later Derrida, focusing on his books, such as The Politics of Friendship, Of Hospitality, On Cosmopolitanism and Forgiveness, etc. Taking an up-close look at Derrida's thought, I argue that his political contemplation of ethics is as effective as his deconstruction of "otherness" in dealing with the nature of ethnic clashes in both the real world and minority literature. In the second half of my paper, I reexamine the issues of race, gender, and class in the three novels of Jamaica Kincaid - Annie John, Lucy, and The Autobiography of My Mother. It is conceivable that from the feminist perspective Kincaid's fiction has been read as a postcolonial Bildungsroman. In my supplementary attempts to this criticism, I reveal that the teenage narrator's precocious awareness is still under the colonial influence in the Annie John section. My analysis of Lucy contends that the reasons why the white woman fails to make friends with the young black woman should be sought in the long history of the U.S. racial politics. In the section of The Autobiography of My Mother, I discuss how difficult it is for a minority woman to liberate from the spell of history insofar as she is engaged in the issue of identity. In closing, I pose a need of consolation that literature may grant us by becoming able to produce a different interpretation on all the bleaker reality.

This study was designed to investigate the relationship between middle school students' smart media competency and online learning outcomes. The context of this study was on online inquiry-based mathematics and science learning environment, and four-hundred and fifty-five (455) 7^th to 9^th grade students in Korea participated in this research. To assess students' smart device competency, Smart Media Literacy Quotient (SMLQ) which consisted of 18 items regarding the operation ability of smart media and its application (14 items) and positive beliefs of smart media (4 items) was administered to each student. The findings of this study first showed that students' smart media literacy varied according to their characteristics such as gender, grade, class (subject), and socio-economic status. Female students' scores were higher in overall smart media literacy operation and learning ability of smart media than male students. 7^th grade middle school students represented lower smart media literacy scores, compared to 8^th and 9^th graders. Also, minority students were significantly lower in smart media literacy, operation and learning ability of smart media, and positive belief of smart media than the non-minority students. Second, overall smart media literacy and operation and learning ability of smart media varied among high, medium, and low score achievers in inquiry tasks. Low scored students in inquiry tasks were significantly lower in overall smart media literacy and operation and learning ability of smart media than medium scored students. Lastly, smart media literacy also varied by students' dropout/completion. Students who dropped out reported significantly lower scores in overall smart media literacy, operation and learning ability of smart media, and positive belief of smart media.

This study aims to analyze the traditional attire of four ethnic minority groups in Northeastern China: Daur, Ewenki, Oroqen, and Hezhen, considering their natural environment, lifestyles, and cultural influences. A literature review of academic papers, books, and online resources was conducted, along with indirect investigations through artifacts. The Daur people, being equestrian, have garments with deep slits, vibrant colors, and elaborate decorations. The Ewenki people wear clothes made of fabric in the summer and primarily deer skin in the winter, and their clothing is simple and not flashy. The Oroqen people's clothing typically has slits at the front, back, or on both sides, and they wear a waist belt. The Hezhen people, an ethnic group that primarily hunts and fishes, wear two-piece clothing with a hip-length top and pants or other fur-trimmed garments. All groups incorporate symbolic patterns influenced by Shamanism, along with animal headgear and leather shoes. We observed that the traditional costumes of ethnic minority groups in Northeastern China share many commonalities in form, but there are detailed differences in material, shape, color, and decoration due to unique geographical and climatic characteristics as well as differences in livelihood. Additionally, the structure of clothing varies depending on each tribe's shamanistic practices and lifestyle.
