Purpose: There has been an increasing focus on consumer ethics by researchers and practitioners alike with the former seeking to examine the general discrepancy between ethical attitude, intention and actual behaviour by proposing behavioural measures to understand ethical consumption. Research into the effects of generational cohorts and gender, two fundamental demographic factors that shape the consumer habituated repertoire, on consumer ethics has reported mixed findings. The present study investigates if there are differences in ethical consumer behavior by generational cohorts and by gender in the context of an emerging market - Vietnam. Research design, data and methodology: Data was collected using a quantitative survey (a link to the questionnaire was posted on relevant social media platforms). A total of 539 usable responses was used for ANOVAs and independent t-tests to test the hypotheses. Results: a) There are significant differences in terms of ethical consumer behavior between Gen Z and Gens Y/X, but no difference between Gen X and Gen Y; b) There is no gender difference in ethically minded consumer behavior. Conclusion: For consumer ethics, generational effects may be moderated by macroeconomic conditions, while gender alone as a biological variable may not be a reliable predictor.

이 논문은 동아시아정체성에 영향을 미치는 연령 및 세대코호트(cohort)효과에 대해 분석한다. 또한 이 논문은 동아시아 지역정체성이 한국인이라는 국가정체성(national identity)의 정도와 어떠한 방식으로 연관되는가를 분석한다. 2008년 시카고국제문제협의회-동아시아연구원에서 실시한 한국인 여론조사 데이터에 대한 분석은 다음과 같은 흥미로운 경험적 발견을 제시한다. 연령이 높을수록 동아시아정체성의 정도가 더 강하게 나타나며, 국가정체성이 강할수록 강한 동아시아정체성을 지니는 경향이 있다. 이러한 경험적 발견은 서구를 대상으로 한 기존연구들의 발견과는 다른 패턴을 보이는 것이다. 첫째, 한국의 경우 젊은 층이 아니라 경제적 자원이 어느 정도 있는 연령층이 더 초국가정체성을 지닌다. 둘째, 일반적인 동북아공동체에 관한 연구의 논의와 다르게, 이 연구는 강한 국가정체성이 동아시아 지역정체성과 상보적(complementary)이라는 점을 제시한다. 이 연구는 동아시아지역통합의 이론적, 정책적 모색과 동아시아 지역 내 강한 민족주의의 관계에 대한 새로운 미시적 기초를 밝혀준다.

The notion of outcome-based educational paradigm and its adaptability for higher education has become a recent growing and quite stirring trend. In the year 2017-18, this educational philosophy has been embraced by some of the higher educational institutions in Pakistan as well. This research attempts to investigate OBE and non-OBE systems in the context of students learning outcomes and academic attainment levels in engineering education in Pakistan. The study has been conducted on undergraduate students of MUET, Jamshoro, Sindh Pakistan. The students of the software engineering department are taken as the sample. Student cohorts are formed i.e., OBE and non-OBE (traditional/teacher-centered approach) cohorts. The summative assessments of semester exams are used for data analysis descriptive statistics and independent samples t-test is performed to set up the group statistic. The findings of this study show that, in terms of students' performance, the OBE system outperforms the traditional system and this transition in engineering institutions might be beneficial in the future.

Interannual and decadal scale changes in body size of Pacific saury, catch and catch per unit effort were examined to investigate the environmental effects on the stock structure and abundance in the Tsushima Warm Current region. Interannual changes in thermal conditions are responsible for the different occurrence (catch) rates of sized group of the fish. Changes in body size due to environmental variables lead the stock to be homogeneous during the period of high abundance, while one of the reminder cohorts supports the stock during the period of low level of abundance. Migration circuits of two cohorts of saury stock are hypothesized on the basis of short life span and spatio-temporal changes of the stock structure in normal environmental conditions. Changes in upper ocean structure and production cycles by the decadal scale climate changes lead changes in stock structure and recruitment, resulting in the fluctuation of saury abundance. Hypothesized mechanism of the effects of climate changes on stock structure and abundance is illustrated on the basis of changes in thermal regime and production cycle.

Background: This study investigated whether current smoking and a higher nicotine dependency were associated with chronic low back pain (LBP), lumbar related leg pain (sciatica) and/or radicular neuropathic pain. Methods: A cross-sectional study was conducted on 150 patients (mean age, 60.1 ± 13.1 yr). Demographic data, the International Association for the Study of Pain (IASP) neuropathic pain grade, STarT Back tool, and the Fagerström test were completed. A control group (n = 50) was recruited. Results: There was a significant difference between current smokers and nonsmokers in the chronic LBP group in the mean pain score (P = 0.025), total STarT Back score (P = 0.015), worst pain location (P = 0.020), most distal pain radiation (P = 0.042), and in the IASP neuropathic pain grade (P = 0.026). There was a significant difference in the mean Fagerström score between the four IASP neuropathic pain grades (P = 0.005). Current smoking yielded an odds ratio (OR) of 3.071 (P = 0.011) for developing chronic LBP and sciatica, and an OR of 4.028 (P = 0.002) for obtaining an IASP "definite/probable" neuropathic pain grade, for both cohorts. The likelihood for chronic LBP and sciatica increased by 40.9% (P = 0.007), while the likelihood for an IASP neuropathic grade of "definite/probable" increased by 50.8% (P = 0.002), for both cohorts, for every one unit increase in the Fagerström score. Conclusions: A current smoking status and higher nicotine dependence increase the odds for chronic LBP, sciatica and radicular neuropathic pain.

The International HapMap Project and the Human Genome Diversity Project (HGDP) provide plentiful resources on human genome information to the public. However, this kind of information is limited because of the small sample size in both databases. A Genome-Wide Association Study has been conducted with 8,842 Korean subjects as a part of the Korea Association Resource (KARE) project. In an effort to build a publicly available browsing system for genome data resulted from large scale KARE GWAS, we developed the KARE browser. This browser provides users with a large amount of single nucleotide polymorphisms (SNPs) information comprising 1.5 million SNPs from population-based cohorts of 8,842 samples. KAREBrowser was based on the generic genome browser (GBrowse), a web-based application tool developed for users to navigate and visualize the genomic features and annotations in an interactive manner. All SNP information and related functions are available at the web site http://ksnp.cdc. go.kr/karebrowser/.
