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.

Objectives: Although Asian immigrants have lower rates of smoking and binge drinking than other ethnics in the US, Korean Americans have the highest rate of Asian immigrants. This study, therefore, compared with the rates and examined the predictors of smoking and binge drinking by gender and ethnicity among Asian immigrants in California. Methods: In 2001 and 2003, California Health Interview Survey (CHIS) were conducted in English and their original languages with Asian immigrants residing in 58 Counties and 3 Cities, California. We performed analysis to find out the differences of smoking and binge drinking rates using the secondary data, CHIS 2001 and 2003. Multiple logistic regression analysis for survey data identified predictors of smoking and binge drinking behaviors by gender and ethnicity. Results: Korean American males (35.4%) and Japanese American females (15.4%) had higher rates of smoking prevalence compared with other Asian immigrants in California. In binge drinking, 26.5% of male and 8.1% of female among Korean Americans were binge drinker, and the rates were the top with Asian Americans who had lived in California. It showed the remarkable gap between gender of smoking and binge drinking among Vietnamese immigrants, whereas not the striking difference among Japanese Americans. In multiple regression models, age, educational level, occupation, marital status, English proficiency, and health insurance coverage remained significant for smoking and binge drinking behaviors(P<0.05). Even though the time in the US was not significant, it seemed to be related to educational level and English proficiency. In particular among female, smoking and binge drinking behaviors were associated with acculturation. Conclusion: Although Asian Americans had shared with American culture since they had immigrated in the US, they had significantly different prevalence rates of smoking and binge drinking based on gender and ethnicity. Therefore, future efforts should be focused on understanding differences by ethnicity and target at high-risk subgroups. To achieve this, it needs to develop the educational materials in Korean and their original languages.

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.

거주지 분화(residential segregation)는 도시 불평등을 심화하는 요인 중 하나이다. 본 연구는 거주지 분화의 원인에 대한 상이한 주장들을 살펴보고 사례분석을 통해 현실 적합성을 검증하고자 한다. 이론적 고찰은 일찍이 논의가 활발했던 미국도시의 인종 민족별 거주지 분화에 대한 것으로 한정하였으며, 거주지 분화가 소수민족의 주류사회로의 낮은 동화에 기인한다고 주장하는 지리적 동화론(spatial assimilation), 주택금융시장의 인종차별에 기인한다는 층화론(place stratification), 그리고 거주지선택에 있어 타민족에 대한 선입관과 자기민족에 대한 선호에 기인한다는 재기되는 민족성론(resurgent ethnicity)을 살펴보았다. 사례 연구로 시카고에 거주하는 아시아인의 거주패턴의 변화를 출신국가별로 지도로 그려 분석하였다. 1990년대를 통한 가장 큰 변화는 교외화와 재집중화로 요약될 수 있으며 이는 민족성론을 그리고 부분적으로 마나 동화론을 뒷받침한다.

Background: Kurdish women with breast cancer have more unfavorable prognostic factors than their Turkish and Arab counterparts. However, the effects of these factors on breast cancer survival among these ethnic groups remain unclear. We therefore investigated the impact of ethnicity on survival in breast cancer patients in Turkey. Materials and Methods: Ethnicity, age, stage at diagnosis, tumor characteristics, treatments given (surgery, chemotherapy, radiotherapy and hormone therapy), and survival times were recorded. Kaplan-Meier analysis was used to estimate the overall survival times and survival plots. Log-rank test was used to compare the survival curves.Results: Of the 723 breast cancer patients included in the study, 496 (68.7%) were Turkish, 189 (26.2%) were Kurdish, 37 (5.1%) were Arabic and 1 was Armenian. Kurdish women with breast cancer had larger tumor sizes and higher rates of hormone receptor negative tumors than Turkish and Arab patients. Mean follow-up time was 118.4 [95% Confidence Interval (CI): 95.4-141.3] months, and it was 129.9 (95% CI: 93.7-166.2), 124.2 (95% CI: 108.4-140.1) and 103.1 (95% CI: 85.9-120.4) months for Turkish, Arabic and Kurdish patients, respectively. Conclusions: Kurdish ethnicity is associated with higher rates of hormone receptor negative and triple-negative tumors and with worse survival. Clinical and epidemiological research is warranted to elucidate reasons underlying overall survival, variations in tumor biology, differences in treatment responsiveness, and effects of social factors among ethnic groups in Turkey.

Background: Chile is one of the countries with the highest prevalence of cholelithiasis worldwide, considering the Mapuche ethnicity as a risk factor for developing this pathology. Moreover, cholelithiasis is the main risk factor for developing gallbladder cancer, being the fifth cause of cancer death in Chile. The purpose of this study was to compare the frequency of cholelithiasis and biliary pathology among the population belonging to Rapanui ethnicity and non-Rapanui population living on Easter Island. Materials and Methods: In this retrospective case-control study, a total of 609 abdominal ultrasonographs performed consecutively in Hanga Roa Hospital during the period August 2012 to January 2015 were analyzed. Multiple logistic regression was used to obtain odds ratio (OR) and 95% confidence intervals (95% CI) of cholelithiasis and biliary pathology, adjusting for age, gender and referral diagnostic hypothesis. Results: In the Rapanui population the frequency for cholelithiasis and biliary pathology was 6.4% and 13%, meanwhile for the non-Rapanui population it was 13% and 22% respectively. Compared to the non-Rapanui Chilean population, the Rapanui ethnicity presented an OR of 0.53 (95% CI: 0.29-0.95) for cholelithiasis and OR of 0.52 (95% CI: 0.33-0.82) for biliary pathology. Conclusions: We found statistically significant ethnic differences in the frequency of cholelithiasis and biliary disease among the population of Rapanui and non-Rapanui ethnicity, so that this could be a protective factor for the development of biliary pathology, given the Chilean population context. Other studies including community population to determine the real prevalence of cholelithiasis and analyze the protective role of Rapanui ethnicity on this disease are necessary.

Purpose: This study aimed to assess the prevalence of smoking, alcohol consumption, physical activity and diet and to identify sociodemographic factors related with health behaviors among Asian immigrant women in Korea by ethnicity. Methods: A cross-sectional study using structured questionnaires was conducted in 396 immigrant women from China, Vietnam, and the Philippines to Korea through international marriage. The associations between health behaviors and sociodemographic characteristics were assessed using multivariate logistic regression analyses. Results: The prevalence of current smoking, alcohol consumption, physical inactivity, and abnormal diet were 4.2%, 7.6%, 49.3%, and 31.9%, respectively. The prevalence of current smoking (7.6%) and physical inactivity (56.7%) was highest in Chinese immigrant women. However, the prevalence of current smoking (2.7%) and alcohol consumption (3.8%) were lowest in Vietnamese immigrant women. Immigrant women who had been living in Korea for a long time since immigration (${\geq}$ 5 years) had a higher prevalence of alcohol consumption compared to those of who had been living in Korea for a short time since immigration (< 5 years) (OR=2.95, 95% CI=1.74-5.01). Conclusion: Health promotion programs for immigrant women should be differentiated based on health behaviors and their related factors by ethnicity.

Background: Glutathione-S-transferase (GST) is an important phase II xenobiotic compound metabolizing enzyme family, involved in tolerance to a particular drug or susceptibility to a diseasec. This study focused the GSTM1 and T1 null allele frequency in the Gujarat population with a comparison across other Inter- and Intra-Indian ethnic groups to predict variation in the possible susceptible status. Methods: DNA was isolated by a salting out method and GSTM1 and T1 homozygous null genotypes were detected by multiplex polymerase chain reaction in 504 unrelated individuals. The genotype distribution of null alleles was compared with Indian and non Indian ethnics reported earlier in the literature using Fisher's test. Results: The frequencies of the homozygous null genotypes of GSTM1 and GSTT1 were 20% (95%CI 16.7-23.9) and 35.5% (95%CI 31.4-39.9) respectively. GSTM1 null frequency did not deviate from most other Indian ethnic groups but differed from the majority of those of non Indian ethnicity studied. The frequency of homozygous null type of GSTT1 was significantly higher and deviated from all Indian groups and a few of non Indian ethnicity. Conclusions: Gujarat ethnicity, possibly the most susceptible for GSTT1 dependent drug disposition and diseases regarding effects of pollution. Further, the results have implications for GSTT1 dependent drugs used for treatment, a serious problem which needs to be solved by physicians and clinical researchers.

Variants of X-ray repair cross-complementing group 1 (XRCC1) are involved in the development of cancer, but studies investigating the association of XRCC1-77T>C polymorphism with cancer risk have reported conflicting results. To clarify the effect of the XRCC1 -77T>C polymorphism on cancer risk, we performed a meta-analysis by conducting searches of the published literature in PubMed, Embase and CBM databases. Finally, 13 studies were included into our meta-analysis, involving a total of 11, 678 individuals. Subgroup analyses were performed by ethnicity and cancer type. The results of this meta-analysis showed that there was significant association between the C variant of XRCC1-77T>C polymorphism and cancer risk in all four genetic comparison models (ORC vs. T =1.19, 95%CI 1.07-1.31, P = 0.001; OR homozygote model =1.28, 95%CI 1.07-1.52, P = 0.007; OR recessive genetic model =1.22, 95%CI 1.04-1.44, P = 0.015; OR dominant model =1.21, 95% CI 1.07-1.35, P = 0.001). In the subgroup analyses based on ethnicity, the association was still significant in the Asian population (all p values<0.001), but not in the Caucasian population (all p values > 0.05). Thus, the XRCC1 -77T>C polymorphism is associated with cancer risk, and individuals with XRCC1 -77C variant have a significantly higher cancer risk, particularly in the Asian population.
