Race in Romance: Racialized Femininity and Intimacy between Asian Female and non-Asian male

The film “Racing Romance” is a study of Asian female and non-Asian male intimacy. The film is based on an understanding that intimacy, desire and love are critical parts of one’s self-identification, while these desires are inevitably influenced by the historical and social contexts of race to varying degrees. There has been a limited academic interest in the female agency of Asian women in interracial intimacy. Too often, interracial marriages and relationships are simply celebrated as part of multiculturalism or anti-racism, without getting proper attention to the subtleties of racial and gendered dynamics that influence both members of the relationship. This film is dedicated to providing platform for Asian women to talk about their experiences and the construction of their identities, while interrogating the gendered and racialized strategies they employ in response to existing stereotypes. The film adopts stylistic features of essay film and reflexive cinema, emphasizing the transparency of relationship between the film and the viewers. Through its content and form, “Racing Romance” attempts to connect the audience through shared Asian womanhood

Less-forgetful Learning for Domain Expansion in Deep Neural Networks

Expanding the domain that deep neural network has already learned without accessing old domain data is a challenging task because deep neural networks forget previously learned information when learning new data from a new domain. In this paper, we propose a less-forgetful learning method for the domain expansion scenario. While existing domain adaptation techniques solely focused on adapting to new domains, the proposed technique focuses on working well with both old and new domains without needing to know whether the input is from the old or new domain. First, we present two naive approaches which will be problematic, then we provide a new method using two proposed properties for less-forgetful learning. Finally, we prove the effectiveness of our method through experiments on image classification tasks. All datasets used in the paper, will be released on our website for someone's follow-up study.Comment: 8 pages, accepted to AAAI 201

Online home appliance control using EEG-Based brain-computer interfaces

Brain???computer interfaces (BCIs) allow patients with paralysis to control external devices by mental commands. Recent advances in home automation and the Internet of things may extend the horizon of BCI applications into daily living environments at home. In this study, we developed an online BCI based on scalp electroencephalography (EEG) to control home appliances. The BCI users controlled TV channels, a digital door-lock system, and an electric light system in an unshielded environment. The BCI was designed to harness P300 andN200 components of event-related potentials (ERPs). On average, the BCI users could control TV channels with an accuracy of 83.0% ?? 17.9%, the digital door-lock with 78.7% ?? 16.2% accuracy, and the light with 80.0% ?? 15.6% accuracy, respectively. Our study demonstrates a feasibility to control multiple home appliances using EEG-based BCIs

Clinical Observation Reflections from Students in an Interdisciplinary Palliative Care Course

The purpose of this study was to gain insight into how a brief clinical observation encounter contributed to students’ experiences in an interdisciplinary palliative care course. This course was required of all graduate nursing students and was available as an elective for medical and other healthcare professions students at a healthcare sciences university. The students were required to spend approximately 8 to 12 hours attending interdisciplinary team meetings or accompanying a team on rounds and patient visits. The students’ summary narratives of their observation experience were analyzed in this qualitative study that focused on six categories of feedback: (1) patients’ and families’ reactions, (2) communication issues with patients and families, (3) how the palliative care team speaks with the patient and family, (4) communication within the interdisciplinary team, (5) students’ reflections, and (6) students’ suffering. This study demonstrated that a clinical observation activity can be a valuable introduction to palliative care principles for healthcare students in an interdisciplinary course. Students benefited from gaining insight into family/practitioner communications regarding difficult issues, interdisciplinary roles and cooperation, and application of palliative care principles to clinical practice. Further research is required to identify appropriate interventions to deal with student distress resulting from such early career clinical encounters

Crystal structure of human endothelial overexpressed lipopolysaccharide-associated factor 1

학위논문 (석사)-- 서울대학교 대학원 약학대학 약학과, 2017. 8. 한병우.Endothelial-overexpressed LPS-associated factor 1 (EOLA1) is a novel gene discovered in an effort to identify genes expressed in endothelial cells by activation of lipopolysaccharide. Previous study demonstrates that knocking down EOLA1 stimulated interleukin-6 (IL6) and apoptosis in the treatment of LPS in human umbilical vein endothelial cells (HUVEC). Analysis of the sequence of EOLA1, revealed that it has ASCH (activating signal cointegrator-1 homology) domain containing a unique β-barrel fold similar to pseudouridine synthase and archaeosine transglycosylase (PUA) domain. Because PUA domain is an ancient RNA binding domain, both ASCH and PUA domain appear to have arisen from a common RNA binding precursor. Here, I report the crystal structure of EOLA1 at 1.7 Å resolution by single wavelength anomalous dispersion (SAD) method using selenomethionine derivative crystals to solve the phasing problem. I demonstrated that EOLA1 could bind with RNA through gel mobility shift assay. Based on these results, I propose that EOLA1 is a RNA binding domain and would play regulatory roles in transcription or in protection of HUVEC injury with inflammation.I.Introduction 1 II.Materials and Methods 4 1.

Effect of ProRoot MTA® and Biodentine® on osteoclastic differentiation and activity of mouse bone marrow macrophages

Objectives: This investigation aimed to assess the differentiation inhibitory effects of ProRoot MTA® (PMTA) and Biodentine® (BIOD) on osteoclasts originated from murine bone marrow macrophages (BMMs) and compare these effects with those of alendronate (ALD). Materials and Methods: Mouse BMMs were cultured to differentiate into osteoclasts with macrophage colonystimulating factor and receptor activator of NF-κB (RANKL), treated with lipopolysaccharide. After application with PMTA, BIOD, or ALD, cell toxicities were examined using WST-1 assay kit, and RANKL-induced osteoclast differentiation and activities were determined by resorption pit formation assay and tartrate-resistant acid phosphate (TRAP) staining. The mRNA levels of osteoclast activity-related genes were detected with quantitative real time polymerase chain reaction. Expressions of molecular signaling pathways were assessed by western blot. All data were statistically analyzed with one-way ANOVA and Tukey’s post-hoc test (p<0.05). Results: Mouse BMMs applied with PMTA, BIOD, or ALD showed highly reduced levels of TRAP-positive osteoclasts. The BIOD treated specimens suppressed mRNA expressions of cathepsin K, TRAP, and c-Fos. Nonetheless, it showed a lower effect than PMTA or ALD applications. Compared with ALD, PMTA and BIOD decreased RANKL-mediated phosphorylation of ERK1/2 and IκBα. Conclusions: PMTA and BIOD showed the inhibitory effect on osteoclast differentiation and activities similar to that of ALD through IκB phosphorylation and suppression of ERK signaling pathways

Perspectives on E-scooters use: A multi-year cross-sectional approach to understanding e-scooter travel behavior in Portland, Oregon

Unique travel behavior patterns are observed as shared electric scooters (e-scooters) provided by private operators expand into U.S. cities. Three separate years of e-scooter ridership survey data from the Portland Bureau of Transportation’s E-scooter Pilot Programs were analyzed to ascertain the multi-year cross-sectional and demographic characteristics of e-scooter riders. A binary logistic regression model, descriptive statistics, and multiple regression model are used to analyze e-scooter mode substitution, trip purposes, and travel distance from 2018 to 2020 in Portland, Oregon. Since the introduction of e-scooter in 2018, respondents have been less likely to use their previous transportation, and especially vehicle trips were consistently replaced with e-scooter trips during three different periods of analysis. In 2020, utilitarian trips, work/school trips, and trips for accessing transit stops replaced recreation trips as the primary trip purpose. The travel distance model shows that e-scooters can help to reduce vehicle miles traveled (VMT) by replacing car and ride-hail/taxis trips. With the result of this research, this study supports shared e-scooters as a viable transportation mode in the future that can achieve several policy goals, such as climate change, congestion, first/last mile connector to transit, and equity
