Exploration of Women’s Experiences of Sexual Function after Female
Genital Cosmetic Surgery: A Phenomenological Descriptive Study
Authors: Nezhad Fatemeh Touhidi , Jalali Rostam , Karimi Fozieh , Menati Lida
Published: March 2022

Background:

Female genital cosmetic surgery (FGCS) consists of a set of design approaches
to recover or strengthen the vulva. These cosmetic procedures are conducted to relieve
functionality problems such as vaginal looseness and sexual dissatisfaction. The external genital
tract is shaped cosmetically. Its results could be better judged through understanding the direct experience
of women who underwent surgery. Therefore, this study aimed to explain the experiences of
women regarding FGCS through phenomenological methods.

Methods:

In a phenomenological study with purposive sampling, semistructured in-depth interviews
were conducted on women who experienced FGCS. Then, the interviews were entered into the
Word software and were analyzed by the Colaizzi 7-step method. To ensure the correctness of the
data, the Guba’s criteria were used. Data were analyzed using MAXQDA software version 10.

Results:

The results showed that 15 women aged between 23-49 years old and with a mean age of 34 years old, mostly married and housewives as well as with diploma educational level participated in the study, three themes and eight subthemes were excluded from the analysis of participants’ interview. Participants presented their experiences on their sexual function after FGCS as sexual satisfaction, high-quality life, and willingness for surgery.

Conclusion:

The studies showed those women’s experiences with FGCS were positive, resulting in
sexual satisfaction and higher quality of life. Therefore, the assessment of women to perform cosmetic
surgery should be prioritized, and the women should be supported to make a decision regarding
such surgery.
Pioglitazone, Bladder Cancer, and the Presumption of Innocence
Authors: Papaetis Georgios S.
Published: March 2022

Background:

Thiazolidinediones are potent exogenous agonists of PPAR-γ that augment
the effects of insulin to its cellular targets, mainly at the level of adipose tissue. Pioglitazone,
the main thiazolidinedione in clinical practice, has shown cardiovascular and renal benefits in patients
with type 2 diabetes, durable reduction of glycated hemoglobulin levels, important improvements
of several components of the metabolic syndrome, and beneficial effects of non-alcoholic
fatty liver disease.

Objective:

Despite all of its established advantages, the controversy for an increased risk of developing
bladder cancer, combined with the advent of newer drug classes that achieved major cardiorenal
effects, have significantly limited its use spreading a persistent shadow of doubt for its future
role.

Methods:

Pubmed, Google, and Scope databases have been thoroughly searched, and relevant
studies were selected.

Results:

This paper thoroughly explores both in vitro and in vivo (animal models and humans)
studies that investigated the possible association of pioglitazone with bladder cancer.

Conclusion:

Currently, the association of pioglitazone with bladder cancer cannot be based on solid
evidence. This evidence cannot justify its low clinical administration, especially in the present
era of individualised treatment strategies. Definite clarification of this issue is imperative and urgently
anticipated from future high quality and rigorous pharmacoepidemiologic research, keeping
in mind its unique mechanism of action and its significant pleiotropic effects.

Mechanism
Authors: Zheng Pengyi , Rao Yuan
Published: March 2022

Background:

With the continuous development of big data, artificial intelligence,
the Internet of things, and blockchain technology, distributed interactive systems
have gradually become the mainstream of computing technologies and applications with
the help of real-time interaction platforms. The real-time interaction platforms provide a
data communication bridge for distributed applications, not only meeting the timeliness
and correctness of data interaction but also providing a unified interface for application
development. It realizes the plug and play of different functional modules in the distributed
system and improves development efficiency for system developers.

Objective:

According to the characteristics of the large scale, wide range, and complex
running environment of distributed interaction systems, this paper analyzes the function
and performance requirements of the distributed interactive platform and designs and implements
a real-time interactive platform named NetDDS based on a publish-subscribe
mechanism.

Methods:

Concerning the idea of a layered design, the real-time interactive platform is
constructed from three aspects: distribution service layer, QoS guarantee layer, and data
transmission layer. The platform provides a data synchronization function based on publish/
subscribe mechanism, a configurable QoS guarantee mechanism, and a multi-protocol
data transmission mechanism based on Ethernet, ensuring the real-time correctness and
reliability of data transmission.

Results:

Experimental results show that the interactive platform exhibits less delay in message
update.

Conclusion:

This paper proposes a hierarchical architecture, designs and implements a
real-time interaction platform based on publish/subscribe mechanism, and provides a topic-
based publish/subscribe model to the application layer. The publisher and subscriber
directly publish and subscribe with data as the center to meet the real-time requirements of
distributed real-time applications.

Authors: Choi Eun-Ji , Jun Tae Joon , Park Han-Seung , Lee Jung-Hee , Lee Kyoo-Hyung , Kim Young-Hak , Lee Young-Shin , Kang Young-Ah , Jeon Mijin , Kang Hyeran , Woo Jimin , Lee Je-Hwan
Published: March 2022

Background

Scoring systems developed for predicting survival after allogeneic hematopoietic cell transplantation (HCT) show suboptimal prediction power, and various factors affect posttransplantation outcomes.

Objective

A prediction model using a machine learning–based algorithm can be an alternative for concurrently applying multiple variables and can reduce potential biases. In this regard, the aim of this study is to establish and validate a machine learning–based predictive model for survival after allogeneic HCT in patients with hematologic malignancies.

Methods

Data from 1470 patients with hematologic malignancies who underwent allogeneic HCT between December 1993 and June 2020 at Asan Medical Center, Seoul, South Korea, were retrospectively analyzed. Using the gradient boosting machine algorithm, we evaluated a model predicting the 5-year posttransplantation survival through 10-fold cross-validation.

Results

The prediction model showed good performance with a mean area under the receiver operating characteristic curve of 0.788 (SD 0.03). Furthermore, we developed a risk score predicting probabilities of posttransplantation survival in 294 randomly selected patients, and an agreement between the estimated predicted and observed risks of overall death, nonrelapse mortality, and relapse incidence was observed according to the risk score. Additionally, the calculated score demonstrated the possibility of predicting survival according to the different transplantation-related factors, with the visualization of the importance of each variable.

Conclusions

We developed a machine learning–based model for predicting long-term survival after allogeneic HCT in patients with hematologic malignancies. Our model provides a method for making decisions regarding patient and donor candidates or selecting transplantation-related resources, such as conditioning regimens.
Nurses’ Perspectives on an Electronic Medication Administration Record in Home Health Care: Qualitative Interview Study
Authors: Karnehed Sara , Erlandsson Lena-Karin , Norell Pejner Margaretha
Published: March 2022

Background

eHealth is considered by policy makers as a prerequisite for meeting the demands of health care from the growing proportion of older people worldwide. The expectation about what the efficiency of eHealth can bring is particularly high in the municipal home health care sector, which is facing pressure regarding resources because of, for example, earlier discharges from hospitals and a growing number of patients receiving medications and treatments at home. Common eHealth services in home health care are electronic medication administration records (eMARs) that aim to communicate delegated tasks between professionals. However, there is an extensive gap in the research on how technology affects and is experienced by home health care professionals.

Objective

The objective of this paper is to shed light on how home care nurses experience eMARs in a Swedish municipality.

Methods

This qualitative interview study was conducted among home health care nurses using eMARs to facilitate communication and signing of delegated nursing tasks. The analysis of the interviews was performed using constructivist grounded theory, according to Charmaz.

Results

Of the 19 day-employed nurses in the municipality where an eMAR was used, 16 (84%) nurses participated in the study. The following two categories were identified from the focus group interviews: nurses become monitors and slip away from the point of care. The nurses experienced that they became monitors of health care through the increased transparency provided by the eMAR and the measurands they also applied, focusing on the quantitative aspects of the delegated nursing tasks rather than the qualitative aspects. The nurses experienced that their monitoring changed the power relations between the professions, reinforcing the nurses’ superior position. The experience of the eMAR was regarded as transitioning the nurses’ professional role—away from the point of care and toward more administration—and further strengthened the way of managing work through delegation to health care assistants.

Conclusions

Previous analyses of eHealth services in health care showed that implementation is a complex process that changes health care organizations and the work of health care professionals in both intended and unintended ways. This study adds to the literature by examining how users of a specific eHealth service experience its impacts on their daily work. The results indicate that the inscribed functions in an eHealth service may affect the values and priorities where the service is in use. This presents an opportunity for future research and for health care organizations to assess the impacts of specific eHealth services on health care professionals’ work and to further examine the effects of inscribed functions in relation to how they may affect actions and priorities at individual and organizational levels.
Discussions of Asperger Syndrome on Social Media: Content and Sentiment Analysis on Twitter (Preprint)
Authors: Gabarron Elia , Dechsling Anders , Skafle Ingjerd , Nordahl-Hansen Anders
Published: March 2022

BACKGROUND

On May 8, 2021, Elon Musk, a well-recognized entrepreneur and business magnate, revealed on a popular television show that he has Asperger syndrome. Research has shown that people’s perceptions of a condition are modified when influential individuals in society publicly disclose their diagnoses. It was anticipated that Musk's disclosure would contribute to discussions on the internet about the syndrome, and also to a potential change in the perception of this condition.

OBJECTIVE

The objective of this study was to compare the types of information contained in popular tweets about Asperger syndrome as well as their engagement and sentiment before and after Musk’s disclosure.

METHODS

We extracted tweets that were published 1 week before and after Musk's disclosure that had received >30 likes and included the terms “Aspergers” or “Aspie.” The content of each post was classified by 2 independent coders as to whether the information provided was valid, contained misinformation, or was neutral. Furthermore, we analyzed the engagement on these posts and the expressed sentiment by using the AFINN sentiment analysis tool.

RESULTS

We extracted a total of 227 popular tweets (34 posted the week before Musk’s announcement and 193 posted the week after). We classified 210 (92.5%) of the tweets as neutral, 13 (5.7%) tweets as informative, and 4 (1.8%) as containing misinformation. Both informative and misinformative tweets were posted after Musk’s disclosure. Popular tweets posted before Musk’s disclosure were significantly more engaging (received more comments, retweets, and likes) than the tweets posted the week after. We did not find a significant difference in the sentiment expressed in the tweets posted before and after the announcement.

CONCLUSIONS

The use of social media platforms by health authorities, autism associations, and other stakeholders has the potential to increase the awareness and acceptance of knowledge about autism and Asperger syndrome. When prominent figures disclose their diagnoses, the number of posts about their particular condition tends to increase and thus promote a potential opportunity for greater outreach to the general public about that condition.
Epidemiology, Secondary School Curricula, and Preparing the Next Generation for Global Citizenship (Preprint)
Authors: Basch Charles E , Basch Corey H
Published: March 2022

UNSTRUCTURED

Because COVID-19 and other emerging infectious diseases are likely to play an increasingly important role in shaping American and global society in years to come, there is a need to prepare young people to make informed decisions in this changing global context. One way to do so is teaching and learning about basic principles of epidemiology in secondary schools. Improved understanding about the agent of infection, mechanisms of transmission, factors that increase or decrease susceptibility, place variation and environmental factors that facilitate or hinder transmission, reservoirs of infection (where the agent lives and multiplies), and when the disease is more or less likely to occur comprise the main facts about an infectious disease relevant to prevention and control. Improved understanding of these basic concepts could help future generations make informed decisions in a changing global context with emerging infectious diseases and a plethora of widely disseminated misinformation and disinformation. This viewpoint considers why learning about epidemiology in secondary school would benefit population health using COVID-19 as an illustration.
The Effect of Fear of Infection and Sufficient Vaccine Reservation Information on Rapid COVID-19 Vaccination in Japan: Evidence From a Retrospective Twitter Analysis (Preprint)
Authors: Niu Qian , Liu Junyu , Kato Masaya , Nagai-Tanima Momoko , Aoyama Tomoki
Published: March 2022

BACKGROUND

The global public health and socioeconomic impacts of the COVID-19 pandemic have been substantial, rendering herd immunity by COVID-19 vaccination an important factor for protecting people and retrieving the economy. Among all the countries, Japan became one of the countries with the highest COVID-19 vaccination rates in several months, although vaccine confidence in Japan is the lowest worldwide.

OBJECTIVE

We attempted to find the reasons for rapid COVID-19 vaccination in Japan given its lowest vaccine confidence levels worldwide, through Twitter analysis. 

METHODS

We downloaded COVID-19–related Japanese tweets from a large-scale public COVID-19 Twitter chatter data set within the timeline of February 1 and September 30, 2021. The daily number of vaccination cases was collected from the official website of the Prime Minister’s Office of Japan. After preprocessing, we applied unigram and bigram token analysis and then calculated the cross-correlation and Pearson correlation coefficient (r) between the term frequency and daily vaccination cases. We then identified vaccine sentiments and emotions of tweets and used the topic modeling to look deeper into the dominant emotions. 

RESULTS

We selected 190,697 vaccine-related tweets after filtering. Through n-gram token analysis, we discovered the top unigrams and bigrams over the whole period. In all the combinations of the top 6 unigrams, tweets with both keywords “reserve” and “venue” showed the largest correlation with daily vaccination cases (r=0.912; P<.001). On sentiment analysis, negative sentiment overwhelmed positive sentiment, and fear was the dominant emotion across the period. For the latent Dirichlet allocation model on tweets with fear emotion, the two topics were identified as “infect” and “vaccine confidence.” The expectation of the number of tweets generated from topic “infect” was larger than that generated from topic “vaccine confidence.”

CONCLUSIONS

Our work indicates that awareness of the danger of COVID-19 might increase the willingness to get vaccinated. With a sufficient vaccine supply, effective delivery of vaccine reservation information may be an important factor for people to get vaccinated. We did not find evidence for increased vaccine confidence in Japan during the period of our study. We recommend policy makers to share accurate and prompt information about the infectious diseases and vaccination and to make efforts on smoother delivery of vaccine reservation information.
What About the Management Perspective? – A Systematic Review of Digital Health Literature (Preprint)
Authors: Angerer Alfred , Stahl Johanna , Krasniqi Egzona , Banning Stefan
Published: March 2022

BACKGROUND

New digital health technologies are considered one solution to challenges in the health sector, which include rising numbers of chronic diseases and increased health spending. As digitalization in healthcare is still in its infancy, there are many unanswered questions about the impact of digital health on management.

OBJECTIVE

This paper assesses the current state of knowledge in the field of digital health from a management perspective. It highlights research gaps within this field to determine future research opportunities.

METHODS

A systematic review of digital health literature was conducted using three databases. The chosen articles (n=38) were classified according to a taxonomy developed for the purpose and research gaps were identified based on the topic areas discussed.

RESULTS

The literature review revealed a slight prevalence of practical (55%) over theoretical (45%) approaches. Most of the papers (61%) deal with information technology (IT) and are, therefore, focused more on technology and less on management. Most of them (82%) have a research question dealing with the creation of concepts; very few (11%) evaluate or even question existing solutions. Most consider the main reason for digitalization to be the optimization of operational processes (68%); 42% deal with new business models. The topic area discussed most frequently was found to be eHealth (79%). By contrast, the field of tech health with topics such as sensors receives the least attention (8%), despite its significant potential for healthcare processes and strategy.

CONCLUSIONS

Three main research propositions were identified. First, research into digital health should focus less on the technology and more on the implications it has for management. Second, the research community should target other domains besides eHealth. Third, we observed a lack of quantitative research on the real impact of digital health on organizations and their management.
Technological innovation in health care: a holistic approach to telemedicine adoption (Preprint)
Authors: Schmitz Anne , Díaz-Martín Ana M. , Yagüe Guillén María Jesús
Published: March 2022

UNSTRUCTURED

The aim of this paper is to offer a holistic and integrative approach to telemedicine adoption in an international context. A modified version of UTAUT2, specifically tailored to the telemedicine field, analyzes the factors that influence the usage intention of virtual doctor appointments from a patient's point of view. The research model furthermore integrates one of the core constructs of the Diffusion of Innovations Theory [1], namely relative advantage, and empirically projects the theoretical framework onto three countries that encounter themselves in different stages of the telemedicine adoption curve: Germany, Spain, and the United States of America.
A mixed-methods approach was used, and the hypothesis were tested applying structural equation modelling (AMOS 24). It was found that performance expectancy, hedonic motivation, habit, relative advantage and perceived security positively impact the usage intention of virtual doctor appointments, Additionally, it has been shown that age moderates the relationships between effort expectancy and hedonic motivation and usage intention, and gender moderates performance expectancy, hedonic motivation and habit.
In the last part of the study, the managerial implications are discussed alongside the limitations and future research lines.
Digital Devices for Assessing Motor Functions in Mobility Impaired and Healthy Populations: A Systematic Literature Review (Preprint)
Authors: Guo Christine C. , Chiesa Patrizia Andrea , de Moor Carl , Fazeli Mir Sohail , Schofield Thomas , Hofer Kimberly , Belachew Shibeshih , Scotland Alf
Published: March 2022

BACKGROUND

With the advent of smart sensing technology, mobile and wearable devices can provide continuous and objective monitoring and assessment of motor function outcomes.

OBJECTIVE

We aimed to describe the existing scientific literature on wearable and mobile technologies that are being used or tested for assessing motor functions in mobility-impaired and healthy adults, and to evaluate the degree to which these devices provide clinically valid measures of motor function in these populations.

METHODS

A systematic literature review was conducted by searching Embase, MEDLINE®, CENTRAL (January 1, 2015 – June 24, 2020), the United States and European Union clinical trial registries, and the United States Food and Drug Administration website using predefined study selection criteria. Study selection, data extraction, and quality assessment were performed by two independent reviewers.

RESULTS

Ninety-one publications representing 87 unique studies were included. The most represented clinical conditions were Parkinson’s disease (k = 51 studies), followed by stroke (k = 5), Huntington’s disease (k = 5), and multiple sclerosis (k = 2). A total of 42 motion-detecting devices were identified, and the majority (k = 27; 64%) were created for the purpose of healthcare-related data collection, though approximately 25% were personal electronic devices (e.g., smartphones, watches) and 11% were entertainment consoles (e.g., Microsoft Kinect/Xbox™, Nintendo Wii™). The primary motion outcomes were related to gait (k = 30), gross motor movements (k = 25), and fine motor movements (k = 23). As a group, sensor-derived motion data showed a mean sensitivity of .83 (SD = 7.27), mean specificity of .84 (SD = 15.40), mean accuracy of .90 (SD = 5.87) in discriminating between diseased individuals and healthy controls, and mean Pearson’s r validity coefficient of .52 (SD = 0.22) relative to clinical measures. We did not find significant differences in the degree of validity between in-lab and at-home sensor-based assessments, nor between device class (i.e., healthcare-related device, personal electronic devices, entertainment consoles).

CONCLUSIONS

Sensor-derived motion data can be leveraged to classify and quantify disease status for a variety of neurological conditions. However, most of recent research on digital clinical measures is derived from proof-of-concept studies with considerable variation in methodological approaches, and much of the reviewed literature has focused on clinical validation, with less than a quarter of the studies performing analytical validation. Overall, future research is crucially needed to further consolidate that sensor-derived motion data may lead to the development of robust and transformative digital measurements intended to predict, diagnose, and quantify neurological disease state and its longitudinal change.
mHealth technology design and evaluation for early childhood health promotion: A systematic literature review (Preprint)
Authors: DeWitt Akeiylah Sammon , Kientz Julie A , Rucker Coker Tumaini , Liljenquist Kendra
Published: March 2022

BACKGROUND

Recent increases in smartphone ownership among underserved populations have inspired researchers in medicine, computing, and health informatics to design and evaluate mobile health (mHealth) interventions, specifically for those supporting child development and growth. While these interventions demonstrate possible effectiveness at larger scales, few of these interventions are evaluated to address racial disparities and health equity, which are known factors that affect relevance, uptake, and adherence in target populations.

OBJECTIVE

In this study, we aimed to identify and document the current design and evaluation practices of mobile health technologies that promote early childhood health, with a specific focus on opportunities for those processes to address health disparities and health equity.

METHODS

To survey the current design and evaluation methods of current work, identify opportunities to address racial disparities in early- and late-stage processes, and understand the potential efficacy of these interventions, we completed a systematic literature review of studies that design and evaluate mHealth interventions for early childhood health promotion.

RESULTS

Across literature from medical, computing, and health informatics venues, we identified 15 papers that presented a design or evaluation of a parent-facing health intervention. We found that using mobile-based systems to deliver health interventions was generally well accepted for parents of children under age five. We also found that, when measured, parenting knowledge of early childhood health topics and confidence to engage in health-promoting behaviors improved. Design and evaluation methods held internal consistency within disciplines (e.g., experimental study designs were most prevalent in medical literature, while computing researchers used user-centered design methods in computing venues). However, there was little consistency in design or evaluation methods across venues.

CONCLUSIONS

To support more interventions undergoing a comprehensive design and evaluation process, we recommend attention to design at the intervention level (e.g., reporting content sources) and at the system level; interdisciplinary collaboration in early childhood health intervention development can lead to large-scale deployment and success among populations.

Published: March 2022

BACKGROUND

HIV self-testing (HIVST) has been rapidly scaled up and additional strategies further expand testing uptake. Secondary distribution involves people (defined as “indexes”) applying for multiple kits and subsequently sharing them with people (defined as “alters”) in their social networks. However, identifying key influencers is difficult.

OBJECTIVE

This study aimed to develop an innovative ensemble machine learning approach to identify key influencers among Chinese men who have sex with men (MSM) for secondary distribution of HIVST kits.

METHODS

We defined three types of key influencers: (1) key distributors who can distribute more kits, (2) key promoters who can contribute to finding first-time testing alters, and (3) key detectors who can help to find positive alters. Four machine learning models (logistic regression, support vector machine, decision tree, and random forest) were trained to identify key influencers. An ensemble learning algorithm was adopted to combine these 4 models. For comparison with our machine learning models, self-evaluated leadership scales were used as the human identification approach. Four metrics for performance evaluation, including accuracy, precision, recall, and F1-score, were used to evaluate the machine learning models and the human identification approach. Simulation experiments were carried out to validate our approach.

RESULTS

We included 309 indexes (our sample size) who were eligible and applied for multiple test kits; they distributed these kits to 269 alters. We compared the performance of the machine learning classification and ensemble learning models with that of the human identification approach based on leadership self-evaluated scales in terms of the 2 nearest cutoffs. Our approach outperformed human identification (based on the cutoff of the self-reported scales), exceeding by an average accuracy of 11.0%, could distribute 18.2% (95% CI 9.9%-26.5%) more kits, and find 13.6% (95% CI 1.9%-25.3%) more first-time testing alters and 12.0% (95% CI –14.7% to 38.7%) more positive-testing alters. Our approach could also increase the simulated intervention’s efficiency by 17.7% (95% CI –3.5% to 38.8%) compared to that of human identification.

CONCLUSIONS

We built machine learning models to identify key influencers among Chinese MSM who were more likely to engage in secondary distribution of HIVST kits.

Authors: Ahmad Dr. Ahmad Fathulla
Published: March 2022

Staff providing services to clients is a common feature of the private sector. To remain competitive, the private sector must maintain high-quality and consistent services. The aim of this study to analyze the influence of interpersonal conflict, job stress, and work life balance on employee turnover intention. Quantitative research was applied to measure the current study. A random sampling method was used to gather data. The researchers distribute 120 questionnaires. 112 questionnaires were received but only 104 questionnaires were valid. The findings revealed that the value B for Interpersonal conflict factor is .611 (.611>0.01) therefore first research hypothesis was supported. The value B for Job stress factor is .599 (.599<0.01) therefore second research hypothesis was supported. The value B for Work life balance factor is .643 (.643>0.01) therefore third research hypothesis was supported. Although the literature shows that turnover has a negative impact on many organizations, this study provides evidence that this relationship has an impact on the pesticide sector in this region.

“Petticoat Fever” Driven by Chosŏn Korea Garments: Exploring a “fad” in Early Ming China and Its Implications for Regional Interactions between the Chosŏn and Ming Dynasties
Authors: Koo Doyoung
Published: March 2022

In the fifteenth century, Chosŏn Korean clothes were exported to the Jiangnan (江南) region in Ming China and became very popular among wealthy Chinese people. This was the so-called “Petticoat Fever”. This horsehair petticoat (Mamigun 馬尾裙) gave the wardrobe a fashionable silhouette by supporting and fully spreading the outer skirt. Literati wore them, too. Mamigun fashion, which once enjoyed great popularity in the Jiangnan area, disappeared after it was prohibited during the Ming period due to a change in power and a transition in policymaking. On the other hand, this study is also significant in that it corrects errors in the study of art history in Ming Dynasty. This study analyzed in detail "Ming Emperor Xianzong's Tour of the Lantern Festival(明憲宗元宵行樂圖)" in the collection of the National Museum of China. I argued that the picture was not a royal court painting (宮中畵), drawned in Beijing, but a piece painted in the Jiangnan area of the Ming dynasty. The artist adopted the mamigun fashion widely enjoyed in the region at the moment in order to express the most splendid and glamourous adornments one could imagine in the place of entertainment for the emperor during the Lantern Festival. "Ming Emperor Xianzong's Tour of the Lantern Festiva" is a clue to the customs and fashion culture of the Jiangnan area of Ming Dynasty in the 15th century. Many works of scholarship in Korea-China relations have tended to argue that culture and trade between Chosŏn and Ming Dynasties in the 15th century were exchanged only through envoys between Seoul of Chosŏn and Beijing of Ming. Mamigun is an interesting topic that gives us insight into the cultural exchange between the Chosŏn and Ming and can also be described as an episode that involves Cheju Island of Chosŏn and Jiangnan region of Ming, both regions that were marginal within Korea-China relations. This study will contribute to extending the scope of the history of exchange between Chosŏn Korea and Ming China by taking a broader perspective.
To Realize Our Decolonization: South Korea’s Deployment of Troops to Vietnam
Authors: Shin Dongil
Published: March 2022

In the 1960s, less than two decades after its liberation, South Korea was still struggling to establish its position in the postwar international order amid waves of decolonization and the Cold War. As a newly independent country, South Korea had one task it considered to be of utmost importance: gaining international recognition by demonstrating its sovereignty to the world. This article focuses on Korea's nation-building process in this context through the dispatch of its troops to Vietnam, a crucial component of completing its decolonization. The subsequent text assesses what factors influenced South Korea's deployment of troops to Vietnam and how this policy gained greater social acquiescence. Koreans perceived the postwar international order as little changed from the previous era of imperialism, when Korea’s sovereignty had been forcefully usurped by Japan. This colonial experience, I contend, conditioned South Korea’s decision to deploy troops to Vietnam; the South Korean government adopted a method familiar to them of showing off its military power to gain international recognition. This logic also explains why domestic actors generally viewed the troop dispatch as legitimate, including intellectuals and opposing politicians who agreed that their country should pursue international recognition using all possible methods, including force.
Discontinuities and Discrepancies in the Hybridization Process of Nangnang Culture
Authors: Benedittis Andrea de
Published: March 2022

This article analyses some “discrepancies” in the development of Nangnang society with a view to finding an alternative historical narrative for the territory, namely one that can explain some processes in Nangnang’s history from the point of view of the local people. In the absence of any records written by contemporaneous inhabitants of Nangnang, we try to examine some discrepancies in the course of the local culture’s development, aiming to glean some evidence that could be interpreted as resistance—a form of silent reaction to external rule. Though we are well aware of the limits of this kind of approach, mostly due to the scarcity of primary sources, this attempt is relevant in consideration of the sensitive nature of this chapter of East Asian history, which has often been constrained to narrow identities and ideological frames.
The Conundrum of Queen Min’s Portrait: A Denied or Partial Identity?
Authors: Bruno Antonetta L. , Kim Kukjin
Published: March 2022

Queen Min (1851-1895) is described in numerous texts including diaries and newspaper articles written by Western, Japanese and Korean authors who lived in Korea between the late 19th and early 20th centuries. However, she is without visual identity, i.e., facial identity, even though King Kojong (1864-1907) referred to the existence of a portrait. This article holds that visual and non-visual identities are complementary to a person. It argues that in the case of Queen Min, the missing visual record generates a de-personification of her identity and that this contributes to the tarnishing of her public and private role in the period prior to Japan’s annexation of Korea. The paper also discusses the history of the queen’s visual identity, which is missing from official history, and inquires into its significance.

Published: March 2022

By employing the Nikiforov-Uvarov functional analysis (NUFA) method, we
solved the radial Schrodinger equation with the shifted Morse potential
model. The analytical expressions of the energy eigenvalues,
eigenfunctions and numerical results were determined for selected values
of the potential parameters. Variations of different thermodynamic
functions with temperature were discussed extensively. Different quantum
information theories including Shannon entropy, Fisher information and
Fisher-Shannon product of the shifted Morse potential were investigated
numerically and graphically in position and momentum spaces for ground
and first excited states. The quantum information theories considered
satisfied their corresponding inequalities including
Bialynicki–Birula–Mycielski, Stam–Cramer–Rao inequalities and the
Fisher–Shannon product relation.
CONTINENT-WIDE PATTERNS OF SONG VARIATION PREDICTED BY CLASSICAL RULES OF BIOGEOGRAPHY
Authors: Sebastianelli Matteo , Lukhele Sifiso , Nkwankwo Emmanuel , Hadjioannou Louis , Kirschel Alex
Published: March 2022

Physiological constraints related to atmospheric temperature pose a
limit to body size in endothermic animals. This relationship has been
summarized by two classical principles of biogeography: Bergmann’s and
Allen’s rules. Body size may also constrain other phenotypic traits
important in ecology, evolution and behaviour, and such effects have
seldom been investigated at a continental scale. Through a
multilevel-modelling approach, we demonstrate that continent-wide
morphology of related African barbets follows predictions of both
ecogeographic rules, and that body size mirrors variation in song pitch,
an acoustic trait important in species recognition and sexual selection.
Bergmann’s rule effects on song dwarf those of acoustic adaptation at a
continental scale. Our findings suggest that macroecological patterns of
body size can influence phenotypic traits important in ecology and
evolution, and provide a baseline for further studies on the effects of
environmental change on bird song.
Seismic Characterization of Internal Salt Cycles: A Case Study in the Santos Basin, Brazil
Authors: Pontes Rodrigo Leandro Bastos , Maul Alexandre Rodrigo , Silva Cleverson Guizan
Published: March 2022

ABSTRACT. The exploration of pre-salt reservoirs in the Santos Basin, Brazilian Offshore, requires innovative approaches to improve the quality of reservoir seismic images below large salt bodies, helping to enhance the depth predictions and to improve security for drilling operations. Salt is a general term for evaporites that may present an enormous complexity. Outcrop and experimental data show that evaporites precipitate in a controlled and defined order, respecting increasing brine salinity. When analyzing the Ariri Formation (salt section) in the Santos Basin we recognize several evaporation salt cycles, indicating climatic and tectonic controls. In this work, we identify the salt cycles in wells and integrate those with the seismic data as low-frequency events to create detailed velocity models. Our results confirm that the incorporation of the salt cycles reduces the average mismatch of depth positioning, consequently, providing reliable volumetric estimations.Keywords: evaporitic section, salt cycles, seismic imaging, seismic inversion, velocity model. Caracterização Sísmica de Ciclos Evaporíticos: Estudo de Caso na Bacia de Santos, BrasilRESUMO. A exploração de reservatórios do pré-sal na Bacia de Santos, Offshore Brasileiro, requer abordagens inovadoras para melhorar a qualidade das imagens sísmicas dos reservatórios abaixo de grandes corpos de sal, ajudando a tornar mais as previsões de profundidade mais precisas e a aumentar a segurança das operações de perfuração. Sal é um termo geral para evaporitos que podem apresentar uma enorme complexidade. Dados experimentais e de afloramentos mostram que os evaporitos precipitam em ordem bem controlada e definida, respeitando o aumento da salinidade da salmoura. Ao analisar a Formação Ariri (seção de sal) na Bacia de Santos reconhecemos vários ciclos de evaporação do sal, indicando controles climáticos e tectônicos. Neste trabalho, identificamos os ciclos de sal em poços e os integramos aos dados sísmicos como eventos de baixa frequência para criar modelos de velocidade detalhados. Nossos resultados confirmam que a incorporação dos ciclos de sal reduz o erro médio do posicionamento em profundidade e, consequentemente, fornecendo estimativas volumétricas mais confiáveis.Palavras-chave: seção evaporítica, ciclos salinos, imageamento sísmico, inversão sísmica, modelo de velocidade.
