Lactase non-persistence (LNP), one of the causes of lactose intolerance, is related to lactase gene associated single nucleotide polymorphisms (SNPs). Since the frequency of LNP varies by ethnic group and country, the research to reveal the presence or absence of LNP for specific people has been conducted worldwide. However, in East Asia, the study of lactase gene associated SNPs have not been sufficiently examined so far using ancient human specimens from archaeological sites. In our study of Joseon period human remains (n=14), we successfully revealed genetic information of lactase gene associated SNPs (rs1679771596, rs41525747, rs4988236, rs4988235, rs41380347, rs869051967, rs145946881 and rs182549), further confirming that as for eight SNPs, the pre-modern Korean people had a lactase non-persistent genotype. Our report contributes to the establishment of LNP associated SNP analysis technique that can be useful in forthcoming studies on human bones and mummy samples from East Asian archaeological sites.

Paranormal Beliefs: Using Survey Trends from the USA to Suggest a New Area of Research in Asia

Kim, Jibum,Wang, Cory,Nunez, Nick,Kim, Sori,Smith, Tom W.,Sahgal, Neha Center for Asian Public Opinion ResearchCollaborat 2015 Asian journal for public opinion research Vol.2 No.4

Americans continue to have beliefs in the paranormal, for example in UFOs, ghosts, haunted houses, and clairvoyance. Yet, to date there has not been a systematic gathering of data on popular beliefs about the paranormal, and the question of whether or not there is a convincing trend in beliefs about the paranormal remains to be explored. Public opinion polling on paranormal beliefs shows that these beliefs have remained stable over time, and in some cases have in fact increased. Beliefs in ghosts (25% in 1990 to 32% in 2005) and haunted houses (29% in 1990, 37% in 2001) have all increased while beliefs in clairvoyance (26% in 1990 and 2005) and astrology as scientific (31% in 2006, 32% in 2014) have remained stable. Belief in UFOs (50%) is highest among all paranormal beliefs. Our findings show that people continue to hold beliefs about the paranormal despite their lack of grounding in science or religion.

Materials and design of nanostructured broadband light absorbers for advanced light-to-heat conversion

Kim, Jong Uk,Lee, Sori,Kang, Seung Ji,Kim, Tae-il The Royal Society of Chemistry 2018 Nanoscale Vol.10 No.46

<P>Light-to-heat conversion systems have been attracting growing research interest in the last few decades, due to their highly intriguing photothermal properties and their wide applications ranging from biomedical applications to solar energy harvesting to mechanical actuators. In general, because the light-to-heat conversion efficiency depends strongly on the absorbing material, significant efforts have been focused on fabricating broadband light absorbers. However, there are several challenges associated with the design and fabrication of light absorbers, such as minimizing heat loss, and optimizing the broadband light absorption and omnidirectional light absorption. Thus, the rational design of enhanced light absorbers is critical to achieve efficient light absorption over a broad wavelength range. In this paper, we introduce the basic theory of light absorption and heat transfer, then summarize fundamental understanding of representative light-to-heat conversion agents including carbon-based, semiconductor-based and plasmonic metal-based materials and structures, and highlight state-of-the-art structural designs towards the development of broadband light absorbers. In addition, the practical applications of these materials and designs are also discussed.</P>

Recent Advances in Unconventional Lithography for Challenging 3D Hierarchical Structures and Their Applications

Kim, Jong Uk,Lee, Sori,Kim, Tae-il Hindawi Limited 2016 Journal of nanomaterials Vol.2016 No.-

<P>In nanoscience and nanotechnology, nanofabrication is critical. Among the required processes for nanofabrication, lithography is one of core issues. Although conventional photolithography with recent remarkable improvement has contributed to the industry during the past few decades, fabrication of 3-dimensional (3D) nanostructure is still challenging. In this review, we summarize recent advances for the construction of 3D nanostructures by unconventional lithography and the combination of two<I>top-down</I>approaches or<I>top-down</I>and<I>bottom-up</I>approaches. We believe that the 3D hierarchical nanostructures described here will have a broad range of applications having adaptable levels of functional integration of precisely controlled nanoarchitectures that are required by not only academia, but also industry.</P>

Lee, Sori,Park, Byeonghak,Kim, Jun Sik,Kim, Tae-il IOP 2016 Nanotechnology Vol.27 No.47

<P>The patterning of high-resolution-featured deep-nanoscale structures with a high aspect ratio (AR) has received increasing attention in recent years as a promising technique for a wide range of applications, including electrical, optical, mechanical and biological systems. Despite extensive efforts to develop viable nanostructure fabrication processes, a superior technique enabling defect-free, high-resolution control over a large area is still required. In this review, we focus on recent important advances in the designs and processes of high-resolution nanostructures possessing a high AR, including hierarchical and 3D patterns. The unique applications of these materials are also discussed.</P>

종교유형과 종교활동 참석빈도가 자살태도에 미치는 영향

김솔이(Kim, Sori),김지범(Kim, Jibum) 한국인구학회 2016 한국인구학 Vol.39 No.4

한국에서 자살은 심각한 사회문제가 되었다. 종교 그리고 종교활동 참석빈도와 같은 종교성은 사회통합 및 사회적 지원과 연관되어 자살을 억제하는 역할을 함에도 불구하고, 한국에서 종교와 자살에 대한 연구는 미비한 실정이다. 본 연구는 종교유형과 종교활동 참석빈도가 자살태도에 미치는 영향을 살펴본다. 분석을 위해, 2013년 한국종합사회조사(KGSS) 자료(N=1,139)를 토대로 종교유형과 종교활동 참석빈도의 상호작용(interaction) 효과로 생성된 7개의 독립변수(불교 자주 참석, 불교 드물게 참석, 개신교 자주 참석, 개신교 드물게 참석, 천주교 자주 참석, 천주교 드물게 참석, 종교 없음)를 이용하여 음이항 회귀분석(negative binomial regression analysis)을 수행하였다. 분석 결과, 종교유형과 관계없이 종교활동에 자주 참석할 때 자살태도가 부정적으로 나타났고, 종교가 있지만 자주 참석하지 않는 사람은 종교가 없는 사람과 비교해서 자살태도에 차이가 없는 것으로 밝혀졌다. 본 연구는 자살 연구에 있어서 종교유형뿐만 아니라 종교성(예, 참석빈도)을 동시에 고려해야 할 필요가 있음을 함의한다. Suicide has been a serious social problem in Korea. Despite half the population have religion, only a few studies have examined the role of religion on suicide. Using the 2013 Korean General Social Survey (N=1,139), we examined how the interaction of religious affiliation and religious attendance was associated with attitudes toward suicide. Using the negative binomial regression model, we found that those who have high rates of religious service attendance are more likely to have a negative attitude toward suicide than those who have lower rates of religious service attendance, regardless of religion. Also, compared to those who have no religion, Buddhists, Protestants, and Catholics whose attendance were low showed no significant difference in their attitude towards suicide. This study concludes that both religious affiliation and religious attendance are important factors in attitudes on suicide and suggests that religious factors should be considered in the study of suicide in Korea.

불안민감도가 과제 수행과 스트레스 반응에 미치는 영향: 우울감의 조절효과

김소리(Sori Kim),이정현(Jung Hyun Lee) 대한스트레스학회 2019 스트레스硏究 Vol.27 No.2

본 연구는 불안민감도가 과제수행과 스트레스 반응에 미치는 영향을 살펴보고, 이 과정에 우울감은 어떠한 영향을 미치는지 확인하였다. 참가자들은 제한된 시간에 암산 문제를 완수하였고, 불안민감도지수와 우울증 선별도구에 응답하였다. 더불어, 실험 전후 참가자들의 코르티졸(Cortisol) 변화량을 확인하였다. 그 결과, 불안민감도가 높은 사람은 과제수행의 정확도가 떨어지고 코르티졸 수치가 유의미하게 상승하였다. 또한, 불안민감도와 우울감이 모두 높은 참가자들이 코르티졸 수치가 가장 크게 상승하였다. 본 연구는 자기보고식 응답에 근거하여 임상증상을 기술하는 것을 넘어 과제수행의 정확도와 생화학적 지표를 함께 제시함으로써, 보다 안정적으로 개인의 불안민감도와 우울감의 관계를 논의하였다는 의의를 지닌다. Backgoround: This study aimed to examine the influence of anxiety sensitivity on task performance and physiological stress response, and to assess the effect of depression in this process for the youth population. Methods: We presented participants with an uncontrollable stress situation where they were required to perform mental arithmetic, based on the Montreal Imaging Stress Task (MIST). A total of 29 participants volunteered for this study. They completed the Anxiety Sensitivity Index-Revised and Patient Health Questionnaire-9 to measure their levels of anxiety sensitivity and depression. Two saliva samples, one before and one after the experiment, were collected to assess the change in cortisol levels as an index of physiological stress response. Results: Participants with high anxiety sensitivity showed lower performance on the mental arithmetic tasks and a significant increase in a salivary cortisol level, compared to those with low anxiety sensitivity. Furthermore, cortisol levels showed a remarkable increase where high anxiety sensitivity was coupled with depressed mood. In other hands, the levels of cortisol remained unchanged despite high anxiety sensitivity with low depressed mood. Conclusions: Our results confirm that the interaction between anxiety sensitivity and depression affects participants’ task performance and stress response, as measured through behavioral tasks and physiological data with self-report indices. Also, through the physiological data, we examined that those who have a high level of anxiety sensitivity showed maladaptive responses under high stressful situation.
