Single-nucleotide polymorphisms (SNPs) have been emerging out of the efforts to research human diseases and ethnic disparities. A semantic network is needed for in-depth understanding of the impacts of SNPs, because phenotypes are modulated by complex networks, including biochemical and physiological pathways. We identified ethnicity-specific SNPs by eliminating overlapped SNPs from HapMap samples, and the ethnicity-specific SNPs were mapped to the UCSC RefGene lists. Ethnicity-specific genes were identified as follows: 22 genes in the USA (CEU) individuals, 25 genes in the Japanese (JPT) individuals, and 332 genes in the African (YRI) individuals. To analyze the biologically functional implications for ethnicity-specific SNPs, we focused on constructing a semantic network model. Entities for the network represented by "Gene," "Pathway," "Disease," "Chemical," "Drug," "ClinicalTrials," "SNP," and relationships between entity-entity were obtained through curation. Our semantic modeling for ethnicity-specific SNPs showed interesting results in the three categories, including three diseases ("AIDS-associated nephropathy," "Hypertension," and "Pelvic infection"), one drug ("Methylphenidate"), and five pathways ("Hemostasis," "Systemic lupus erythematosus," "Prostate cancer," "Hepatitis C virus," and "Rheumatoid arthritis"). We found ethnicity-specific genes using the semantic modeling, and the majority of our findings was consistent with the previous studies - that an understanding of genetic variability explained ethnicity-specific disparities.

Name separation (splitting full names into surnames and given names) is not a tedious task in a multiethnic country because the procedure for splitting surnames and given names is ethnicity-specific. Malaysia has multiple main ethnic groups; therefore, separating Malaysian full names into surnames and given names proves a challenge. In this study, we develop a two-phase framework for Malaysian name separation using deep learning. In the initial phase, we predict the ethnicity of full names. We propose a recurrent neural network with long short-term memory network-based model with character embeddings for prediction. Based on the predicted ethnicity, we use a rule-based algorithm for splitting full names into surnames and given names in the second phase. We evaluate the performance of the proposed model against various machine learning models and demonstrate that it outperforms them by an average of 9%. Moreover, transfer learning and fine-tuning of the proposed model with an additional dataset results in an improvement of up to 7% on average.

The incidence of hepatocellular carcinoma (HCC) in Malaysia for the year 2001 was 2.8 per 100,000 people. The mortality rate is increasing. A retrospective cohort study measuring the survival of HCC patients who received treatment in Selayang Hospital was conducted from 1 January 2003 to 31 December 2006. The main objectives of the study were to measure the survival of the patients and to understand the influencing factors, especially ethnicity. The subjects were newly diagnosed cases of HCC by CT scan and histopathological assessment who underwent futher investigations and treatments in Hospital Selayang (inception cohort). The survival time was measured from the date of diagnosis until the subjects died, or failed to follow-up at the end of the study period (31 December 2007). A total of 299 patients were selected with 95 patients dying, the majority among Chinese (39.1%). Subgroup analysis according to ethnicity proved significantly that Chinese patients who had smaller tumor, less number of nodules, low AFP level, Child Pugh Class A and received surgical treatment had a better median survival rate compared to other ethnic groups. Malay (cHR: 1.3, 95%CI; 0.89-1.85) and Indian (cHR: 1.3, 95%CI; 0.74-2.26) patients had a poor survival compared to Chinese patients, but not in the final model. Therefore ethnicity may play a role in survival of HCC patients, but not as a main hazard prognostic factor.

Purpose: Demirjian's dental maturity scores and curves have been widely used for human age determination. Several authors have reported considerable differences between the true and estimated age based on the Demirjian curves, which have been accounted for by ethnicity. The purpose of the current study was to assess the role of ethnicity-specific dental maturation curves in age estimation of Saudi children. Materials and Methods: A sample of 452 healthy Saudi children aged 4 to 14 years were aged based on the original French-Canadian Demirjian curves and several modified Demirjian curves specified for certain ethnic groups: Saudi, Kuwaiti, Polish, Dutch, Pakistani, and Belgian. One-way ANOVA and a post hoc Scheff$\acute{e}$'s test were used to assess the differences between chronological age and dental age estimated by the different curves (P<0.05). Results: The curves designed for Dutch, Polish, Saudi, and Belgian (5th percentile) populations had a significantly lower error in estimating age than the original French-Canadian and Belgian (50th percentile) curves. The optimal curve for males was the Saudi one, with a mean absolute difference between estimated age and chronological age of 8.6 months. For females, the optimal curve was the Polish one, with a mean absolute difference of 7.4 months. It was revealed that accurate age determination was not related to certain ethnicity-specific curves. Conclusion: We conclude that ethnicity might play a role in age determination, but not a principal one.

This study was conducted to examine dietary behaviors according to residence status and ethnicity of university students in Yanbian, China. For the subjects, 334 university students (Male=141, Female=193) answered a questionnaire about perception of weight control, dietary patterns, health habits, residence status, and ethnicity. Perception of weight, meal frequency, favorite kind of food, meal finishing time, skipping breakfast, type of breakfast, snack frequency, late-night snack frequency, exercise frequency, regular life, and sleeping time were all significantly associated with residence status. Motivation of weight control, meal frequency, regularity of meal time, meal volume, favorite kind of food, exercise time, and regular life were all significantly associated with ethnicity. University students who lived with their parents perceived their weight more properly, exhibited a more positive dietary pattern, and lived a more regular life than those students who lived in a dormitory with their friends. Chinese students exhibited a more regular dietary pattern and lived a more regular life than the Korean-Chinese students. As a result, both environmental and inherent factors are related with the dietary behaviors of university students in Yanbian, China. These data could be used to help university students in Yanbian, China attain a healthy diet.

얼굴 자극의 성별 및 종족과 라인업 절차에 따른 얼굴 인식에서의 차이를 알아보기 위해 두 편의 실험을 수행하였다. 실험 1에서 사용된 자극은 동남아시아인 및 동북아시아인 남성의 정면 얼굴 이미지였으며 얼굴 자극의 종족과 실험참가자의 종족이 동일할 때 얼굴 인식이 향상될 수 있는지(동종족 우세 효과)를 알아보았다. 실험 2에서는 동북아시아인 남성 및 여성의 정면 얼굴을 자극으로 사용하여 참가자와 얼굴 자극의 성별이 같을 때 얼굴 인식이 더 정확한지(동성별 우세효과) 알아보았다. 두 실험에서 실험참가자는 모두 동북아시아인이었으며 라인업 절차의 동시제시 조건과 순차제시 조건을 사용하여 얼굴 자극 제시 방법에 따른 차이도 비교하였다. 실험결과 동종족 우세 효과와 라인업 절차에 따른 얼굴 인식 정확도의 차이는 관찰되지 않았으나 표적이 동남아시아인 자극일 때 얼굴 인식 정확률이 높았다. 흥미롭게도, 동성별 우세 효과는 여성 실험참가자에 한해 관찰되었다. 이러한 결과를 통해 얼굴 인식이 주의에 의해 영향을 받을 수 있을 가능성에 대해 논의하였다.

세계체제론적 관점에서 본다면, 국제인구이동은 선택적 인구이동이라고 할 수 있으며, 이는 국가간 격차의 심화로 이어진다. 또한 문화적으로 보았을 때, 이는 목적지에서의 민족집단별 경쟁과 갈등. 혹은 조화와 같은복잡한 현상들을 유발한다. 기존의 동화론에 의하면, 민족성은 이주집단이 새로운 정착지에서 오랜기간 동안 생활하다보면 자연스럽게 그 성격이 악화되고. 이에 따라 민족집단의 공간적 격리 현상도 점차 사라지게 되는 것으로 간주된다. 그러나 현재 다민족으로 구성된 국가들에서의 다양한 사례를 보게 되면, 그러한 동화가 매우 더디게 진행되거나 혹은 정반대로 민족성과 민족집단장소가 오히려 강화되는 모습을 확인할 수 있다. 민족성과 민족집단장소의 재발견 혹은 재구성은 현대사회의 다문화주의 및 포스트모더니즘 이념과 밀접한 관련이 있다. 민족성과 민족집단장소는 다민족 국가나 도시에 있어서 문화와 경제를 풍요롭게 하는데 큰 역할을 할 수 있는 귀중한자산인 것이다.

The present study examined generational differences in ethnicity maintenance among Korean-Chinese to understand the impact of recent social change on a Korean-Chinese ethnic community in China. A total of 1355 Korean-Chinese (557 parents and 798 children), who live in Shenyang, China, participated in this study. The subjects were asked about their language use during daily conversations and cultural activities. They were also asked about their ethnic identity and perceptions of social distance from Chinese people. The results reveal that the Korean-Chinese parent generation is more likely to maintain its ethnic language, while the child generation is more likely to maintain its ethnic culture. Second, more parents than children considered themselves as 'Korean-Chinese' rather than 'Chinese'. Third, members of the child generation show less social distance from Chinese people than do the parent generation. These results show a strong tendency towards ethnicity maintenance among Korean Chinese as well as recent changes in the community. This study argues for the importance of school education and school environment in maintaining the ethnic language and culture of Korean-Chinese children.

This paper discusses American disability theater's representations of disability identity and disability identity politics. Dramatists John Belluso and Lynn Manning, among others, present characters with disabilities who experience oppressions at multiple, interlocking levels of domination on the basis of disability, race, and ethnicity. In Manning's Shoot, the black, blind hero iterates episodes in which he experienced discrimination and insults in encounters with whites who used derogatory racist words or belittled him and with some school children who taunted him for just being blind. This play, as in Manning's solo performance, Weights, presents narratives of a blind person traversing multiple locations of oppression in "a long litany of losses" in a white-dominated and ableist society. Belluso's Gretty Good Time similarly weaves together stories of disabled women, Gretty and Hideko, who bond together to resist the dominant ideology that reduces them into titillating commodities of mass consumption. Hideko's story serves the two-fold function of both affirming the specificity of her individual experience as an ethnic other and espousing the communal experience of stigmatization she shares with other disabled women like Gretty. In these plays, the intersection of the identity categories of disability, race, and ethnicity highlights the diversity of the body and the fluidity of boundaries, foregounding the specificity of disabled bodies, while at the same time overthrowing the hierarchical binarism between disabled and "normal" bodies.
