Narratives of Disability and Accessibility
Authors: Charbonneau Deborah , Copeland Clayton , Dali Keren , Mallary Kevin , Smith Andrew J. M. , Thompson Kim M.
Published: October 2022

The COVID-19 global pandemic has presented tremendous health-related challenges that affected workplace dynamics and social interactions. Although effects of the pandemic have been felt worldwide, some communities and individuals have been disproportionately impacted and overlooked in the pandemic response. This ALISE Disabilities SIG session will explore issues around topics related to disability, accessibility, and/or the intersection of both in various LIS educational and library contexts. The proposed session will consist of four interactive panel presentations offering perspectives relevant to the conference theme “From One Narrative to Many,” along with recommendations relevant to LIS educators and practitioners. The overall goal of this panel is to bring attention to the importance of shifting DEI discussions to a more inclusive, and welcoming Inclusion, Diversity, Equity, and Accessibility (IDEA) framework for everyone, with disability and accessibility as integral parts thereof. The panel session will consist of four panel presentations. Presentation topics include: 1) Examining disability definitions and models, 2) Strategies for incorporating universal design for learning (UDL) into online courses, 3) Experiences of disabled and neurodiverse PhD students in LIS during the COVID-19 pandemic, and 4) Defining barriers and identifying solutions for accessible, inclusive teaching and learning environments. At the end of the presentation, panelists will have an opportunity to interact with attendees to discuss the implications of the presentations for a range of various communities such as students, educators, library practitioners, and community members. To help facilitate an interactive discussion format, attendees and panelists will engage together in small group activities and conversations about practices for addressing some of the most pressing issues and concerns highlighted by the COVID-19 pandemic. In addition, attendees will be asked to reflect and comment on how the presented ideas may be applicable to their respective personal and professional environments and attendees will further be invited to share any additional recommendations.
Opposing Epistemicide as First Principle
Authors: Burgess John , Fowler Gina
Published: October 2022

Social epistemology is a theory of knowledge that recognizes the social dimension of knowledge creation. In the LIS context it also serves as an enduring theory of how and why LIS professionals organize collective knowledge of the world. There is a growing awareness among LIS researchers that epistemic and cognitive injustices, and systematic attempts at epistemicide are widespread. Any theory of social epistemology that is meant to guide LIS practice must take into account the moral dimension of harms caused by allowing epistemic injustices to proliferate in information systems. Pivoting to the idea that opposing epistemicide and other injustices is central to the purpose of the LIS profession warrants a reconsideration of how educators discuss the core values in foundations courses.
Open Education Resources: Storing and Accessing Computable Biomedical Knowledge in Libraries
Authors: Swain Deborah , Brown Nijee , Cunningham Christopher
Published: October 2022

Can library science move forward as gatekeepers, creators, and consumers of computable biomedical knowledge or CBK (Williams, et al., 2020)? Yes. This research goes back to library skills to help information scientists and knowledge managers “get it.” Reviewing a pilot class for LIS professionals, we are developing online, sustainable open educational resource (OER) materials for global users. A community of practice will efficiently deliver biomedical applications for researchers, LIS professionals, healthcare providers, and patients. Our brave goal grew from an Institute of Museum and Library Services (IMLS) grant to put library and information professionals in the fore-front designing and maintaining effective medical repositories while collaborating with authors. Access to data is essential to establishing effective Learning Health Systems (LHSs). The vision is to improve healthcare where underutilization of appropriate and overutilization of inappropriate care lead to rising costs, less safety, and health disparities (Friedman, et al., 2017). The “mobilizing CBK” movement from Michigan’s Medical School LHS department is providing infrastructure, metadata, and networks to writing developers worldwide so access to research knowledge supports health-related decisions.

 

Pre- and post-assessments of pilot training by medical providers, health library directors, and LIS educators provided quantitative and qualitative data to design the OER. Fearlessly applying “open pedagogy,” we will support copyright laws but create and share practices that sidestep proprietary entanglements as librarians in Arizona researched (Casey & Daly, 2021).  We are developing an “open textbook” with learning modules like publish in open access, avoid bias, review systematically, redefine librarian’s role, and NLM tools.
Recovering and Reusing Scientific Data
Authors: Sorensen Amanda H. , Fenlon Katrina , Escobar-Vredevoogd Camila , Wagner Travis L.
Published: October 2022

Legacy scientific data relevant to current and future scientific research exist scattered across memory institutions. This data remains unexplored and often faces the potential to be destroyed. This poster focuses on data rescue initiatives within the sciences, exploring how these efforts suggest the need for greater focus on scientific thinking and collaboration between the sciences and LIS.

This research explores the efforts of digital curators and scientists to recover library and archival records housed on obsolete formats (both physical and digital) and data within unpublished documents. The ongoing "Recovering and Reusing Archival Data for Science" project (RRAD-S) draws on semi-structured interviews with scientists from atmospheric sciences to ornithology and data curators, including metadata librarians and archivists. These interviews document the catalysts, priorities, and challenges of participants' data reuse/recovery efforts. This poster reports on initial findings regarding how scientific data rescue entails a degree of digital curation expertise and planning on the part of scientific research teams, meaning that scientists thinking proactively about data preservation or reuse might collaborate with information professionals to develop data conservation plans.

Historically, LIS education dedicates limited attention to understanding scientific thinking, which usually emphasizes generating new data over reuse. This poster asserts that LIS education can support long-term scientific scholarship by consciously educating students to participate in scientific data preservation initiatives. Additionally, educators can utilize scientific data practices to inform LIS pedagogy by prioritizing and centering proactive data creation within scientific endeavors.
Examining the influence of amicus briefs and patents on information policymaking
Authors: McGowan Catherine
Published: October 2022

This study traces a network of strategic power relations between a Google amicus curiae brief and patent to reveal how elite organizations influence information policymaking. The lens of actor-network theory is applied to the selected cases to trace the complex sociotechnical network of heterogeneous relations (Latour, 1993). A microanalysis reveals how information policymaking is influenced by persuasive information presented in amicus briefs and the technical disclosures described in patent claims of black box technologies (Collins, 2018; Frohmann, 1995). This study is part of a larger, mixed methods research project that analyzes over 4,000 geospatial technology patents to reveal the growing trend of inferred geospatial data production where artificial intelligence is leveraged, to demonstrate that constitutional protections for digital privacy rights must incorporate a privacy model that recognizes anonymous data production and not merely user agency to grant consent.

Presently, information policy and data privacy laws are interpreted through a lens of inescapability (Tokson, 2020). This lens situates digital privacy rights within a fallible dichotomic premise that assumes clear, perpetual agency to grant or deny consent to access data. Moreover, the implications of Fourth Amendment rights are exemplified in geofence warrants—an investigative technique that searches location history to identify suspects in a geofenced region and time series in the absence of evidence. Geofence warrants have been utilized to conduct sweeping searches that collect user data of innocent people such as protesters, cyclists, and other passersby. This study offers the potential to improve policymaking to protect the rights of datafied citizens.
Conceptions of Professional Expertise: Implications for Educating Future Librarians
Authors: Hicks Deborah , VanScoy Amy , Julien Heidi
Published: October 2022

Librarianship has struggled with professional identity and power relations, both within the profession, such as between librarians who serve customers face-to-face and those who create and maintain library systems (Harris, 1992), and outside the profession (e.g., on academic campuses, where librarians have maintained a subservient relationship with disciplinary faculty) (Julien & Pecoskie, 2009). Librarianship remains a feminized profession, which generates value from stereotypically female attributes, such as caring and service, rather than from recognized professional and intellectual expertise. VanScoy (2013) found that librarians who identify as women downplay their professional expertise when discussing public service activities. However, subsequent research did not find a similar tendency among librarians of color (VanScoy & Bright, 2017) suggesting that intersectional identities may be at play. These findings merit further study. While a feminist lens has been used to examine librarianship (e.g., Harris, 1992; Lew & Yousefi, 2017), feminism and intersectionality (Crenshaw, 1989) have not been applied to empirical work to a significant extent. We will present preliminary results of an ongoing study exploring librarians’ experience of professional expertise, examined through an intersectional lens. The project includes interviews with 30 librarians representing multiple identities including gender, race, type of role (public-facing and non-public-facing roles), and managerial level. The study intends to amplify marginalized voices, to better understand personal conceptions of professional expertise. This has implications for education future librarians, as they are coached to develop a sense of expertise to support their career ambitions. Implications for educating librarians are the focus of the poster.

Published: October 2022

The use of primary source documents in the pursuit of understanding the complex histories Library and Information Studies (LIS) is essential to connecting the foundations of the profession. The historical perspectives SIG will create a sharing space where attendees can demonstrate how they use artifacts to tell both hidden and known histories. The showing and telling of historical artifacts provide the opportunity for telling historical narratives and fostering community engagement amongst educators and scholars in LIS history and archives. This program explores layered storytelling, with engagement through the expression both of pedagogical experiences and the histories of various historical artifacts. The assembled participants will each share an artifact or story to demonstrate how they use them in LIS courses and research to infuse historical teaching of various topics (Reference, Organization of Information, Collections Development, Youth Services, etc..). The goals for the session are to: 1) Demonstrate the use primary source materials and other artifacts to correct LIS history & hegemonic narratives prevalent in LIS historical studies. 2) Provide various models for students in how to engage with service communities in the telling of unknown histories. 3) Utilize participatory dialogue in sharing narratives in building community around the teaching of LIS history. The session will assist in the development best-practices for the integration of historical materials in LIS courses. It addresses which narratives are missing or need reinforcement in the LIS classroom. Through dialogue the session will answer questions: How can we better include historical contexts throughout the curriculum? What is the role of counterstories? How can we address inclusive histories?
Across the Threshold
Authors: Nelson Sarah
Published: October 2022

It has long been known that stories can be powerful marketing tools for many organizations, including libraries. Existing research has looked at the stories that employees tell about libraries and the stories libraries tell to promote themselves. For this exploratory study a workshop was offered training participants to tell personal, historical, or traditional stories relating to libraries, culminating in a performance. An open mic time during the performance allowed audience members to share their stories as well. Storytellers included library users, a student training to be a librarian, and the library professor/researcher. The stories were coded using Joseph Campbell’s hero’s journey as a framework. By examining these stories we can better understand where libraries and librarians fit on the hero’s journey. These stories help us understand how patrons view and use the library and invite us to imagine the mythic potential of the library as we advertise our services.

Published: October 2022

La pesca de pequeña escala es relevante. Sin embargo, aspectos como la sobrepesca, el crecimiento de la población humana, el estado de los stocks, influyen en la adopción de estrategias de diversificación económica por los pescadores. Este artículo investiga cómo evoluciona este proceso, identificando éxitos y desafíos, y sus contribuciones en los ODS de la Agenda 2030. Se realizó una revisión de alcance y análisis crítico de publicaciones del 2017 al 2022. Se encontró que el proceso de diversificación se gesta a nivel mundial, independientemente de las disimilitudes entre flotas. La diversificación muestra dos vías principales de evolución: en las actividades pesqueras y en actividades no pesqueras de acuerdo al patrimonio de cada región, destacando actividades turísticas, servicios de transporte, alimentos y acuicultura. La política pública, la capacitación y la integración del conocimiento académico se identifican como elementos de éxito, mientras que el control del mercado por mayoristas, sistemas de cuotas y una débil gobernanza destacan como desafíos. Se reconocen aportes importantes en seguridad alimentaria, reducción de pobreza y empleos dignos. No hay evidencia concluyente de sus impactos en ecosistemas sanos.

Published: October 2022

The aim of this paper is to explore the links between climate action, human rights and sustainability. The study is performed through an extensive literature review, combining aspects PRISMA guidelines and the Recursive Content Abstraction (RCA) analytical approach. First, we present the intrinsic relationship between climate change and SDGs, and how their compliance could be affected by climate change. Next, we analyze the evolution of human rights, and how present and future climate change impacts can harm the human rights of the first, second, third and fourth generations. We also discuss the importance of the government´s policies and actions to protect and guarantee human rights within the actual reality of climate change effects, adaptation, and mitigation in the face of sustainable development goals (SDGs). We sustain that both national policies and international cooperation are necessary to affront the climate change challenges, guaranteeing the human rights at the same time. Based on the topics discussed, at the end the paper presents some final remarks.
Examining Chinese Users’ Feedback Comments on HIV Self-testing Kits From e-Commerce Platforms: Thematic and Content Analysis
Authors: Liu Miao , Zhu Yi , Gao Haiqing , Li Jialing
Published: October 2022

Background

HIV self-testing is preferred by many Chinese people for its convenience and confidentiality. However, most studies on HIV self-testing (HIVST) uptake in China overfocused on men who have sex with men and overrelied on obtrusive methods such as surveys and interviews to collect data.

Objective

We aimed to explore Chinese HIVST kit users’ authentic experience via their feedback comments posted on e-commerce platforms using an unobtrusive approach.

Methods

In total, 21,018 feedback comments about buying and using HIVST kits posted on Chinese e-commerce platforms (Tmall and Pinduoduo) were collected. An inductive thematic analysis based on a random sample of 367 comments yielded several thematic features. These thematic features were developed into coding categories for a quantitative content analysis of another random sample of 1857 comments.

Results

Four themes were identified in the first study, including the expression of positive and negative emotions after and before getting the test, respectively, calling for living a clean and moral life in the future, comments on the sellers and HIVST kits, and the reasons for buying HIVST kits. The results from the second study suggested that there were significant associations between different platforms and several thematic features. Nearly 50% of the comments were related to the product itself and the disclosures of HIV-negative test results. More than 25% of the comments showed users’ feelings of gratefulness after receiving negative test results such as “thank heavens for sparing my life.”

Conclusions

The results suggested that Chinese users relied on HIVST kits to reduce and prevent HIV infection, while they also considered HIV infection a punishment related to moral violation such as being sexually promiscuous. The traditional Chinese health belief that health is influenced by one’s morality still persists among some Chinese users. Many users also lacked appropriate knowledge about HIV transmission and self-testing kits.
Investigating Patients' Continuance Intention Toward Conversational Agents in Outpatient Departments: Cross-sectional Field Survey
Authors: Li Xingyi , Xie Shirong , Ye Zhengqiang , Ma Shishi , Yu Guangjun
Published: October 2022

Background

Conversational agents (CAs) have been developed in outpatient departments to improve physician-patient communication efficiency. As end users, patients’ continuance intention is essential for the sustainable development of CAs.

Objective

The aim of this study was to facilitate the successful usage of CAs by identifying key factors influencing patients’ continuance intention and proposing corresponding managerial implications.

Methods

This study proposed an extended expectation-confirmation model and empirically tested the model via a cross-sectional field survey. The questionnaire included demographic characteristics, multiple-item scales, and an optional open-ended question on patients’ specific expectations for CAs. Partial least squares structural equation modeling was applied to assess the model and hypotheses. The qualitative data were analyzed via thematic analysis.

Results

A total of 172 completed questionaries were received, with a 100% (172/172) response rate. The proposed model explained 75.5% of the variance in continuance intention. Both satisfaction (β=.68; P<.001) and perceived usefulness (β=.221; P=.004) were significant predictors of continuance intention. Patients' extent of confirmation significantly and positively affected both perceived usefulness (β=.817; P<.001) and satisfaction (β=.61; P<.001). Contrary to expectations, perceived ease of use had no significant impact on perceived usefulness (β=.048; P=.37), satisfaction (β=−.004; P=.63), and continuance intention (β=.026; P=.91). The following three themes were extracted from the 74 answers to the open-ended question: personalized interaction, effective utilization, and clear illustrations.

Conclusions

This study identified key factors influencing patients’ continuance intention toward CAs. Satisfaction and perceived usefulness were significant predictors of continuance intention (P<.001 and P<.004, respectively) and were significantly affected by patients’ extent of confirmation (P<.001 and P<.001, respectively). Developing a better understanding of patients’ continuance intention can help administrators figure out how to facilitate the effective implementation of CAs. Efforts should be made toward improving the aspects that patients reasonably expect CAs to have, which include personalized interactions, effective utilization, and clear illustrations.
Optimizing Outcomes in Psychotherapy for Anxiety Disorders Using Smartphone-Based and Passive Sensing Features: Protocol for a Randomized Controlled Trial
Authors: Müller-Bardorff Miriam , Schulz Ava , Paersch Christina , Recher Dominique , Schlup Barbara , Seifritz Erich , Kolassa Iris Tatjana , Kowatsch Tobias , Fisher Aaron , Galatzer-Levy Isaac , Kleim Birgit
Published: October 2022

Background

Psychotherapies, such as cognitive behavioral therapy (CBT), currently have the strongest evidence of durable symptom changes for most psychological disorders, such as anxiety disorders. Nevertheless, only about half of individuals treated with CBT benefit from it. Predictive algorithms, including digital assessments and passive sensing features, could better identify patients who would benefit from CBT, and thus, improve treatment choices.

Objective

This study aims to establish predictive features that forecast responses to transdiagnostic CBT in anxiety disorders and to investigate key mechanisms underlying treatment responses.

Methods

This study is a 2-armed randomized controlled clinical trial. We include patients with anxiety disorders who are randomized to either a transdiagnostic CBT group or a waitlist (referred to as WAIT). We index key features to predict responses prior to starting treatment using subjective self-report questionnaires, experimental tasks, biological samples, ecological momentary assessments, activity tracking, and smartphone-based passive sensing to derive a multimodal feature set for predictive modeling. Additional assessments take place weekly at mid- and posttreatment and at 6- and 12-month follow-ups to index anxiety and depression symptom severity. We aim to include 150 patients, randomized to CBT versus WAIT at a 3:1 ratio. The data set will be subject to full feature and important features selected by minimal redundancy and maximal relevance feature selection and then fed into machine leaning models, including eXtreme gradient boosting, pattern recognition network, and k-nearest neighbors to forecast treatment response. The performance of the developed models will be evaluated. In addition to predictive modeling, we will test specific mechanistic hypotheses (eg, association between self-efficacy, daily symptoms obtained using ecological momentary assessments, and treatment response) to elucidate mechanisms underlying treatment response.

Results

The trial is now completed. It was approved by the Cantonal Ethics Committee, Zurich. The results will be disseminated through publications in scientific peer-reviewed journals and conference presentations.

Conclusions

The aim of this trial is to improve current CBT treatment by precise forecasting of treatment response and by understanding and potentially augmenting underpinning mechanisms and personalizing treatment.

Identifying the Question Similarity of Regulatory Documents in the Pharmaceutical Industry by Using the Recognizing Question Entailment System: Evaluation Study (Preprint)
Authors: Saraswat Nidhi , Li Chuqin , Jiang Min
Published: October 2022

BACKGROUND

The regulatory affairs (RA) division in a pharmaceutical establishment is the point of contact between regulatory authorities and pharmaceutical companies. They are delegated the crucial and strenuous task of extracting and summarizing relevant information in the most meticulous manner from various search systems. An artificial intelligence (AI)–based intelligent search system that can significantly bring down the manual efforts in the existing processes of the RA department while maintaining and improving the quality of final outcomes is desirable. We proposed a “frequently asked questions” component and its utility in an AI-based intelligent search system in this paper. The scenario is further complicated by the lack of publicly available relevant data sets in the RA domain to train the machine learning models that can facilitate cognitive search systems for regulatory authorities.

OBJECTIVE

In this study, we aimed to use AI-based intelligent computational models to automatically recognize semantically similar question pairs in the RA domain and evaluate the Recognizing Question Entailment–based system.

METHODS

We used transfer learning techniques and experimented with transformer-based models pretrained on corpora collected from different resources, such as Bidirectional Encoder Representations from Transformers (BERT), Clinical BERT, BioBERT, and BlueBERT. We used a manually labeled data set that contained 150 question pairs in the pharmaceutical regulatory domain to evaluate the performance of our model.

RESULTS

The Clinical BERT model performed better than other domain-specific BERT-based models in identifying question similarity from the RA domain. The BERT model had the best ability to learn domain-specific knowledge with transfer learning, which reached the best performance when fine-tuned with sufficient clinical domain question pairs. The top-performing model achieved an accuracy of 90.66% on the test set.

CONCLUSIONS

This study demonstrates the possibility of using pretrained language models to recognize question similarity in the pharmaceutical regulatory domain. Transformer-based models that are pretrained on clinical notes perform better than models pretrained on biomedical text in recognizing the question’s semantic similarity in this domain. We also discuss the challenges of using data augmentation techniques to address the lack of relevant data in this domain. The results of our experiment indicated that increasing the number of training samples using back translation and entity replacement did not enhance the model’s performance. This lack of improvement may be attributed to the intricate and specialized nature of texts in the regulatory domain. Our work provides the foundation for further studies that apply state-of-the-art linguistic models to regulatory documents in the pharmaceutical industry.
Optimizing the Implementation of Clinical Predictive Models to Minimize National Costs: A Sepsis Case Study (Preprint)
Authors: Rogers Parker , Boussina Aaron E. , Shashikumar Supreeth P. , Wardi Gabriel , Longhurst Christopher A. , Nemati Shamim
Published: October 2022

BACKGROUND

Recent advancements in machine learning (ML) and the proliferation of healthcare data have led to widespread excitement about using these technologies to improve care. Predictive analytic models in domains such as sepsis, acute kidney injury, respiratory failure, and general deterioration have been proposed to improve the timely administration of life-saving treatments and mitigate expensive downstream complications. It has been argued that a more tailored approach that accounts for implementation constraints that may differ across care settings can further enhance the adoption of such systems.

OBJECTIVE

To optimize the parameters of a sepsis prediction model within distinct patient groups to minimize the excess cost of sepsis care and analyze the potential effect of factors contributing to end-user response to sepsis alerts on overall model utility.

METHODS

We calculated the excess costs of sepsis to the Center for Medicare and Medicaid Services (CMS) by comparing patients with and without a secondary sepsis diagnosis but with the same primary diagnosis and baseline comorbidities. We optimized the parameters of a sepsis prediction algorithm across different diagnostic categories to minimize these excess costs. At the optima, we evaluated diagnostic odds ratios and analyzed the impact of compliance factors—like non-compliance, treatment efficacy, and tolerance for false alarms—on the net benefit of triggering sepsis alerts.

RESULTS

Compliance factors significantly contributed to the net benefit of triggering a sepsis alert. However, a customized deployment policy can achieve a significantly higher diagnostic odds ratio and reduced costs of sepsis care. Implementing our optimization routine with powerful predictive models could result in $4.6 billion in excess cost savings for CMS.

CONCLUSIONS

We provide a framework that CMS policymakers could use to recommend minimum adherence rates to the early recognition and appropriate care of sepsis that is sensitive to hospital department-level incidence rates and national excess costs. Customizing the implementation of clinical predictive models by accounting for various behavioral and economic factors may improve the practical benefit of predictive models.

Published: October 2022

What is this summary about?

This is a summary of a research survey called ACTION Teens. In our survey, 12,987 people from 10 countries answered questions about obesity. They were: 5275 teenagers with obesity, 5389 caregivers of teenagers with obesity, and 2323 doctors who provide medical care for teenagers with obesity.

What were the main results of the survey?

Most teenagers with obesity were worried about their weight and thought that losing weight was their responsibility. Many teenagers had already tried to lose weight. For teenagers, wanting to be more fit or in better shape was the top reason for wanting to lose weight. Some caregivers did not realize how worried their teenager was about their own weight. There were also some caregivers who were not aware of their teenager's recent attempts to lose weight. As a group, the doctors did not know the main reasons why teenagers want to lose weight. They also did not know the main reasons preventing teenagers from losing weight.

What do the results of the survey mean?

Teenagers with obesity will be better supported and understood if there is better communication between teenagers, caregivers, and doctors.

Authors: Arivukkodi Dr. G. , Kanmani Dr. S.
Published: October 2022

Abstract: India holds the fourth position in terms of installed wind power with an installed capacity of 40.788GW in July 2022. The country has set itself a national target of 60 GW by 2022. Wind energy still leaves small-scale impacts on the environment and human health. Advanced technologies emerged to make quitter turbines, still, the noise emitted is a cause of concern, especially in the habitats close to the installations. The present study aimed to assess the sensation of annoyance due to the wind turbine’s (WT) noise. in the adjoining inhabited area. An interactive questionnaire survey is conducted in six villages from the three districts in the state of Tamil Nadu. The study group comprised 47 subjects belonging to different age groups profession. The basic objective of conducting the health survey is to understand the influence of wind turbine noise (WTN) on the lifestyle of the common masses residing in the surrounding wind farms. While framing the legislation, noise annoyance due to WTN should be considered with utmost importance, since WTN is more distressing than common sources of noise. From the social and psycho-acoustical survey, it was found that sleep disturbance due to ambient noise is more concern, and also the adult population who participated in the survey attributed the loss of rainfall as the main problem faced due to the advent of the WTs and the Noise from the WTs
Ameliorating Effects of Geumnyeonyijin-tang Water Extract on Obesity-Induced T2DM and Related Complications in Mice
Authors: Lee Yoo-na , Baek Kyungmin , Ku Sae-kwang
Published: October 2022

Objective: The aim of this study was to compare the effects of different doses of Geumnyeonyijin-tang (GNYJT) water extracts with those of metformin (250 mg/kg) in mild diabetic-obese mice.Methods and Results: The 48 mice were divided into 1 normal pellet diet (NFD) group and 5 high-fat diet (HFD) groups. At the end of 12 weeks of oral administration of metformin (250 mg/kg) or GNYJT water extracts (400, 200, or100 mg/kg), the effects were evaluated. The HFD control mice showed noticeable increases in body weight, adipose tissue density, fat pad weight of the periovarian and abdominal wall, and insulin, blood glucose, and HbA1c levels, with decreases in serum HDL levels. Increases in the periovarian and dorsal abdominal fat pad, regions of steatohepatitis, adipocyte hypertrophy, and hepatocyte hypertrophy were also discovered. The HFD group showed a decline in glucose levels and elevation of hepatic gluconeogenesis, suggesting an HFD-induced AMPK downregulation related to glucose dysregulation, as well as lipid metabolism related to obese insulin-resistant type II diabetes, dyslipidemia, and oxidative stress related diabetic hepatopathy (non-alcoholic fatty liver disease, NAFLD).Conclusion: Assessment of the key parameters for inhibition of diabetes and related complications in HFD-fed diabetic-obese mice demonstrated that GNYJT water extracts have favorable ameliorating effects. The effect of GNYJT was manifested through the stimulation of AMPK upregulation of related hepatic glucose enzyme activities and expression of lipid metabolism-related genes. Therefore, appropriate oral dosages of GNYJT could be promising as a new preventive candidate for controlling diabetes and related complications. Further screening of biologically active compounds, elucidation of detailed mechanisms, and more animal studies are warranted.

Methods This study is a case analysis through literature research, which is a method of qualitative research, and examined the data collected through Korean academic information KISS, Academic Research Information Service RISS, and Library of Congress, which are centered on Korean prior research. In the selection process, duplicate content was excluded from the National Assembly Library, KISS, and RISS searches and from all published thesis and academic journals. A total of 12 cases were selected for final research: 10 academic journals and 2 conference papers. The collected data were classified into title by research topic, researcher, year of publication, and publication type. The table was arranged in ascending order by year. Results Through the analysis of previous studies, this study derived 9 key factors of a design thinking-based therapeutic convergence program to improve the resilience of college students. Key factors have been identified as ‘Improving Interpersonal Capacity of Empathy (ES)’, ‘Improving Self-Control through Empathy’ (EC), ‘Improving Self-Control Through Defining (DFC)’, ‘Improving Self-Control through Presenting Ideas (Ideas)’ (IC), ‘Improving Positivity through Ideas (IP)’, ‘Improving Positivity through Prototypes (PP)’, ‘Improving Positivity through Testing (TP)’, ‘Improving Self-Control through Diffusion Thinking (DVC)’, and ‘Improving Self-Control through Convergent Thinking (CC)’. Conclusions Therefore, this study presented the Resilience Design Thinking Process (RDTP) in 6 steps based on the 9 key factors of resilience design thinking derived from the case analysis of prior research. The 6th stage of RDTP was presented as ‘Interpersonal Relationship of Empathizing (ES)’, ‘Self-Regulation through Ideation (IC)’, ‘Self-Regulation through Defining (DFC)’, ‘Positive Ideation (IP)’, ‘Positivity Prototype (Visualization) (PP)’ and ‘Enhancing Positivity through Testing (TP)’.

Objectives The purpose of this study is to present future objectives and further study directions of the qualitative studies on infants by analyzing the trend of the qualitative studies on infants from 2011 through 2021. Methods For this purpose, analyzed the 185 studies on infants published on KCI journals from 2011 through 2021 according to their publication years and their themes. Results Among the 973 articles published on the journals from 2011 through 2021, 19.01% of the total were qualitative studies on infants. The publication of the qualitative studies on infants was on the rise from 2011 through 2019, but it decreased in 2020. The results of this study is as follows. First, 37.30% of the total articles were written on ‘the teachers’ from 2011 through 2021, which is the most of all. From 2011 through 2013, qualitative and ethnography studies occupied 78.09.% of the total articles, but it is decreasing. Even though the number is small, some articles are action studies, narrative studies, phenomenological, and grounded studies. These kinds of studies were increasing from 2020 through 2021. This trend leads to diversification of qualitative studies on infants. The average study period is 3.9 months. Second, a variety of qualitative studies on infants were carried out under the theme of ‘teachers’. 32.97% of the total subjects of the experiments were teachers, which is the most of all. When the subjects were infants, the 2-year-olds are the most of all in terms of ‘development’, ‘curriculum’, and ‘teaching and learning methods’. The most frequently used method of data collection was interviews with teachers and parents. Conclusions Based on these results, this study suggest that diversifying the research theme and research participants, data collection, and collecting data for a sufficient period.

Objectives The purpose of this study was to understand the influence of acculturation pressure of married immigrant women from Korean multicultural families on depression in the children of multicultural adolescents in the first grade of junior high school, and to verify the media effect of the parental efficacy of married immigrant women. Methods To test this, the study used the fourth data from the Multicultural Adolescents Panel Study, which involved 1228 multicultural adolescents and their multicultural mothers. Data analysis was performed using SPSS 26.0 program for frequency analysis, descriptive analysis and Pearson correlation analysis. In addition, Process Macro 4.0 and Model 4 developed by Hayes (2021) were used to test the research model and media effects. Results First, zero-order correlation analysis among mothers’ acculturation stress and parenting efficacy and their children’s depression revealed that there were significant correlations between the main variables. Second, acculturation stress of married immigrant women had a meaningful positive effect on depression in adolescent children, while acculturation stress had a negative effect on parental efficacy. At the same time, the parental efficacy also had a significant negative effect on their children's depression. Finally, parental efficacy of married immigrant women played a mediating role in the relationship between cultural stress in multicultural mothers and adolescent depression. Conclusions The results suggest that depression in children of multicultural adolescents can be addressed by reducing acculturation stress and improving parental efficacy in married immigrant women. Implications to reduce mothers’ acculturation pressure and to prevent and reduce depression in multicultural adolescents were discussed.
