The Refusal to Unlock His/Her Smartphone and Contempt of Court under the Laws of the United States
Authors:   Wonkwang University Legal Research Institute has, Huh Soon Chul
Published: April 2023

What should the government do if they fail to unlock or hack suspect’s locked or encrypted smartphone when executing a legitimate search and seizure warrant? Currently, in South Korea, there is no criminal provision to punish someone for refusing the government’s request to unlock the smartphone. In contrast, Article 49(2) of the Regulation of Investigatory Powers Act 2000 in the U.K., Article 434-15-2 of the French Criminal Code, and Article 3LA of the Crimes Act 1914 in Australia allow the government to require anyone to cooperate in unlocking or decrypting his or her smartphone in limited conditions. The courts in the U.S. have laid down different decisions on the issue of whether compelling the suspect to produce the smartphone in a condition of being unlocked or encrypted is repugnant to his or her privilege against self-incrimination under the Fifth Amendment. The courts, then, have ruled that there would be an exception to the privilege when any potential testimonial communication is the “foregone conclusion doctrine” that adds little or nothing to the total sum of the government’s information. Courts, therefore, usually order suspect to unlock or decrypt his or her smartphone when the government can independently prove some facts regarding the doctrine despite the suspect’s privilege. The courts have indirectly compelled suspect to unlock or encrypt his or her smartphone by holding the suspect in contempt of court if he or she fails to do so. The right to remain silent under the Constitution of the Republic of Korea is not an absolute constitutional right, therefore the right may be limited only by a statutory Act if necessary. According to the proportionality doctrine, it is time to consider if we should adopt a new law which allows courts to order suspect to unlock or decrypt his or her smartphone or to issue a warrant requesting his or her to cooperate with the government by unlocking or decrypting it on condition that the government reasonably places his or her a suspicion of committing a serious felony viewed on the prosecution service’s request and submitted evidence showing the facts not only that it would be impossible or seriously difficult to collect evidence through other investigative methods but also that it seems reasonable to conclude that the suspect knows the passwords and the government identifies the contents it seeks with reasonable particularity.
Interpretation and application of Article 31(4) of the Constitution
Authors:   Wonkwang University Legal Research Institute has, Noh Kiho
Published: April 2023

Article 31, Paragraph 4 of the current Constitution stipulates that “the independence, professionalism, political neutrality of education and the autonomy of universities are guaranteed by the law.” As for the content and scope of what the “autonomy of education, professionalism, political neutrality, and university autonomy” in the Constitution means in detail, the theories that have been established in Article 31, Paragraph 4 are insufficient, and the application of this provision is not yet complete. There are also not many precedents of specific cases throughpolitical neutrality of education and the autonomy of universities are guaranteed by the law.” As for the content and scope of what the “autonomy of education, professionalism, political neutrality, and university autonomy” in the Constitution means in detail, the theories that have been established in Article 31, Paragraph 4 are insufficient, and the application of this provision is not yet complete. There are also not many precedents of specific cases through. Therefore, in this thesis, the concept and meaning of education's autonomy, professionalism, and political neutrality, and specific examples of application were examined, and how they are defined in Japanese education laws, which have similar regulations to ours, and how they are defined in academic theories, theories, and specific precedents. I tried to get implications by comparing and examining whether they are interpreting. And furthermore, we reviewed what is the plan to solve our educational legal issues. It can be said that the concept and meaning of the autonomy of education, professionalism, political neutrality, and university autonomy under Article 31, Paragraph 4 of the Constitution, as well as specific implementation plans, have been established to some extent through academic theories and court precedents. However, if the constitutional purpose of Article 31, Section 4 of the Constitution is interpreted with respect and the legislative purpose of the constitutional authority is respected, it can be said that it ultimately results in the substantial guarantee of the people's right to receive education under Article 31, Section 1 of the Constitution. In order to more practically and concretely realize the people's right to receive education, and narrowly, the student's right to learn, autonomy, professionalism, and political neutrality in education are required. It should be seen that it is implemented as (autonomy). It is necessary for the government to reflect the legislative intent of the Constitution when designing education policies and establishing a system, and the same is true for the courts to interpret and apply the provisions of education.
Enquadramentos da confissão da homossexualidade masculina durante a epidemia de aids no Brasil (1985-1995)
Authors: Souto Maior Paulo
Published: April 2023

Neste artigo analiso os discursos de confissão da homossexualidade masculina na época do surgimento da aids no Brasil. Com a emergência da epidemia e da eleição dos homossexuais como um dos grupos acusados de disseminar a doença, houve um esforço da grande mídia e do cinema brasileiro em incentivar que homossexuais soropositivos se assumissem publicamente. Nesse sentido, a imprensa homossexual dos anos 1980 minimizou discursos de confissão das homossexualidades. A imprensa gay dos anos 1990, por sua vez, resistindo ao discurso estigmatizante e apesar da aids, resolveu se afirmar publicamente homossexual. Reunindo um conjunto de fontes, apresento maneiras e sentidos de enquadrar publicamente homens homossexuais cis durante o contexto da aids.
Vida vigiada: Jaime Cortesão sob as lentes da PIDE/DGS
Authors: Cardoso Lucileide Costa
Published: April 2023

Pensar o ponto de contato entre a historiografia portuguesa e a brasileira no século XX a partir do problema do exílio científico é tomar como primeiro passo e nos limites deste texto, o estudo da trajetória de Jaime Cortesão sob a ótica da polícia política salazarista. O propósito deste artigo é compreender a repressão política que se abateu sobre o poeta-historiador através da investigação dos documentos de natureza repressiva produzidos pela PIDE-DGS. Orientadas pela lógica de suspeição e inculpação, tais fontes são reveladoras da longa vigilância e controle por parte do Estado Novo de atividades acadêmicas e políticas dos intelectuais, especialmente dele, uma das figuras eminentes do republicanismo português e que foi capaz de resistir ao obscurantismo salazarista dentro e fora do seu país.

Herança ibérica, preservacionismo e regionalidade como crítica à modernidade burguesa em Nordeste (1937), de Gilberto Freyre
Authors: Schneider Alberto Luiz
Published: April 2023

O artigo discute "Nordeste", livro que Gilberto Freyre publicou em 1937 na Coleção Documentos Brasileiros, coordenada por ele próprio na Editora José Olympio. O objetivo é compreender a referida obra, articulada à produção intelectual do sociólogo pernambucano no período. A partir do texto freyreano, pretende-se evidenciar como a herança ibérica e a regionalidade conduzem o autor a uma interpretação do preservacionismo das formas antigas de vida, cultura e sociedade, inclusive em relação ao meio ambiente. Freyre coloca-se na defesa da legitimidade histórica da cultura ibérica, já transformada nas condições do Nordeste açucareiro, marcado pelo escravismo e pela monocultura, cuja existência o autor via ameaçada sob a força desagregadora da modernidade industrial que emanaria do Ocidente protestante e capitalista.
La teoría de la degeneración en los estudios médicos sobre la prostitución en Chile. 1920-1940
Authors: Gálvez-Comandini Ana Carolina , Goicovic Donoso Igor
Published: April 2023

Este artículo analiza cómo la idea científica de la degeneración en las prostitutas sirvió para reafirmar su inferioridad humana, y su potencial peligrosidad social, asociada a conductas sexuales desviadas e inmorales, vinculadas al contagio de enfermedades venéreas. En Chile entre 1920 y 1940, gran parte de los saberes médicos y sanitarios sobre la prostitución se construyeron sobre la base de la inferioridad mental en las meretrices y su consecuente degradación moral, como expresión de una herencia mórbida potenciada por un medio ambiente social hostil. La influencia de la teoría de la degeneración, apoyada por la eugenesia y la criminología positivista, contribuyó a crear un estereotipo estigmatizado de prostituta como el epítome de la anormalidad femenina, de la sexualidad desviada y de la moralidad corrupta en las mujeres. Con estos fines, hemos revisado algunos de los principales trabajos de medicina que tratan exclusivamente sobre prostitución producidos en Chile entre 1920 y 1940, que develan las características y paradigmas que permearon la producción médica al respecto.

A Study on the Influencing Factors of Individuals' Intention to Donate in Charitable Crowdfunding
Authors: Yang Dong-shan , Sun Yu-xin
Published: April 2023

Charity crowdfunding has become one of the most important donation channels in the Internet age. Faced with complex personality traits, can charity crowdfunding platforms attract a wide range of people to make donations? By integrating personality theory with cognitivist learning theory (SOR), and with the help of 449 questionnaire data, this paper examines the psychological mechanisms of altruistic and egoistic personality traits participating in crowdfunding donations and reveals the mediating role of media cognition and donation cognition. The study found that individuals with both altruistic and egoistic personality characteristics have the intention to donate in the context of crowdfunding platforms, and the formation of the intention to donate depends on the individual's cognition of crowdfunding donations, including the cognition of crowdfunding (media trust perception) and perception of donation (donation motivation), specifically, in the relationship between personality characteristics and donation intention, the three media trusts (donation platform trust perception, project initiator trust perception, and project text content trust perception) and three kinds of donation motivations (sympathy, guilt, and satisfaction) play an important mediating role, and the mediating mechanisms of altruistic and egoistic personality are slightly different. The research results have certain implications for the development of philanthropy in the Internet context.

Authors: Jiang Wen-xiao , Song Ruo-yu
Published: April 2023

This paper takes 9260 domestic free tourism strategy data collected from the Mafengwo website as samples, quantifies the travel guide texts by using data mining, and performs word frequency statistics and keyword extraction on the data through Python code and NLPIR platform, then divides the high-weight words into three categories that affect the usefulness of information through hierarchical clustering. Ten hypotheses are proposed in the paper based on previous research. And a negative binomial regression model is built to conduct analysis. The results show that when the number of reads is regarded as a control variable, all ten text features, such as the rate of containing pictures, have a significant positive relationship on information usefulness. Therefore, suggestions are provided to develop influential and high-quality tourism strategies in terms of text features.
A Machine Learning-Driven Movie Performance Prediction System to Improve Decision-Making Capability of Movie Investors
Authors: Paul Chiranjib , Das P. K.
Published: April 2023

Moviegoers refer to online audience movie ratings before deciding to watch a movie. They are more inclined to watch a movie with a high average rating. We develop a system to predict average audience movie ratings based on the lead cast and crew at an early stage of movie production. After valuing multiple scenarios, investors can use our study to select the lead cast and crew objectively. Judicious selection of the key cast and crew is extremely important as investors commit to large sums of money as professional fees while signing contracts with them. Our study uses a relatively large sample of 1687 Indian movies spread across 10+ languages released in India between 2010 and 2019 to identify the important predictors influencing average audience movie rating. Identification of important predictors improves the explainability of the prediction model, which increases the investors’ trust in the predicted values. The best model, random forest, reduces the baseline prediction error of the average rating by 10.21%.
Mechanism insights for efficient photocatalytic reforming of formic acid with tunable selectivity: accelerated charges separation and spatially separated active sites
Authors: Ye Xiaoyuan , Dong Yuchen , Zhang Ziying , Zeng Wengao , Zhang Tuo , Liu Feng , Guan Xiangjiu , Guo Liejin
Published: April 2023

Formic acid (FA) is an ideal carrier for hydrogen (H2) and carbon
monoxide (CO). Thus, photocatalytic reforming of FA is considered a
promising energy conversion method for producing solar fuels and
valuable chemical feedstocks to achieve the carbon-neutral goal.
However, the application of FA photocatalytic reforming has been
restricted by the low efficiency and relatively fixed selectivity due to
limited knowledge about the reaction mechanism. Herein, we show 1D
CdS/2D W2N3 heterojunction as an efficient photocatalyst for
photoreforming of FA with tunable selectivity to realize the conversion
of products from H2 to syngas under simulated sunlight. Widely tunable
CO:H2 ratios between 0 and 2.18 along with a record-high apparent
quantum yield (AQY) of 61.00% (H2) and 76.84% (syngas) at 420 nm have
been demonstrated. Both theoretical investigation and experimental
results show that intrinsic N vacancies and spatially separated active
sites are vital factors in achieving tunable selectivity. This work
provides a brand-new strategy and insightful information to construct a
noble-metal-free photocatalytic system for efficiently reforming of FA
with tunable selectivity.
Neuromyelitis Optica and Liver Cirrhosis: An Association Or Co-Incidence
Authors: Kumar Arjun , Das Ananya , Agarwal Mayank , Raina Rohit , Kant Ravi
Published: April 2023

Neuromyelitis Optica (NMO) is a rare central nervous system
demyelination syndrome predominantly targeting optic nerves and the
spinal cord. Here we present a middle-aged female presenting with new
onset quadriparesis and a history of persistent splenomegaly and
pancytopenia, eventually being diagnosed as NMO along with autoimmune
cirrhosis. The association of Neuromyelitis Optica spectrum disorders
(NMOSD) with chronic liver disease has not been previously described in
the literature. The purpose of this case report is to bring forward an
unusual presentation and to ascertain whether it could be part of a
heterogenous spectrum of an autoimmune disorder, or merely a
co-incidence.
Why Animals Construct Helical Burrows: Construction vs. Post-Construction Benefits
Authors: Doody Sean , Hasiotis Stephen , Shukla Shivam
Published: April 2023

The extended phenotype of helical burrowing behavior in animals has
evolved independently many times since first appearing after the
Cambrian explosion (~540 million years ago). A number of
hypotheses have been proposed to explain the evolution of helical
burrowing in certain taxa, but no study has searched for a general
explanation encompassing all taxa. We reviewed helical burrowing in both
extant and extinct animals and from the trace fossil record and compiled
from the literature 10 possible hypotheses for why animals construct
helical burrows, including our own ideas. Of these, six were
post-construction hypotheses—-benefits to the creator or offspring,
realized after burrow construction—-and four were construction
hypotheses reflecting direct benefits to the creator during
construction. We examined the fit of these hypotheses to a total of 21
extant taxa and ichnotaxa representing 59–184 spp. Only two
hypotheses—-antipredator, biomechanical advantage—-could not be
rejected for any species (possible in 100% of spp.), but six of the
hypotheses could not be rejected for most species (possible in 86–100
% of spp.): microclimate buffer, reduced falling sediment (soil),
anticrowding, vertical patch, and the above two hypotheses. Four of
these six were construction hypotheses, raising the possibility that
helical burrowing might have evolved without providing post-construction
benefits. Our analysis showed that increased drainage, deposit feeding,
microbial farming, and offspring escape could not explain helical
burrowing behavior in the majority of taxa (5–48%). Overall, the
evidence does not support a general explanation for the evolution of
helical burrowing in animals. The function and evolution of the helix as
an extended phenotype would seem, at least in some cases, to provide
different advantages for different taxa. Although direct tests of many
of the hypotheses would be difficult, we nevertheless offer ways to test
some of the hypotheses for selected taxa.
Gas exchange parameters for the prediction of obstructive sleep apnea in infants
Authors: Gyapay Romane , Ioan Iulia , Thieux Marine , Guyon Aurore , Ayari Sonia , Hullo E. , Franco Patricia , Coutier Laurianne
Published: April 2023

Objectives/background: Sleep laboratory polysomnography (PSG) is the
gold standard for obstructive sleep apnea (OSA) diagnosis in infants,
but its access remains limited. Another simple and widely used tool,
oximetry-capnography can provide information on the presence of
desaturations and alveolar hypoventilation. However, its reliability is
debated. This study aimed at examining its use in determining OSA
severity in infants. Patients/methods: This retrospective study was
conducted in a sleep unit in a tertiary hospital, in infants <
4 months old with clinical signs of OSA or Pierre Robin Sequence (PRS)
who underwent a one-night PSG coupled with oximetry-capnography.
Results: Among the 78 infants included (median [IQR] age: 61
[45-89] days at PSG), 44 presented with PRS, and 34 presented with
isolated airway obstruction. The clinical, sleep and respiratory
characteristics were not significantly different between the two
subgroups. In the entire cohort, 63.5% had severe OSA. Median OAHI was
14.5/h [7.4-5.9], Spo2 was 97.4% [96.5-98.1], and PtCO2 was
41.1 mmHg [38.3-44.9]. The optimal threshold to predict OAHI
> 10/h was 6/h for OD3% (sensitivity 95.7%, specificity
51.9%) and 2/h for OD4% (sensitivity 95.7%, specificity 48.1%).
Conclusion: Whereas transcutaneous capnography does not appear to be
sufficient in predicting severe OSA in infants < 4 months old
with PRS or clinical signs of OSA, oximetry may be a useful alternative
for the screening of severe OSA in infants in the absence of PSG.
Predicting Mobile Money Transaction Fraud using Machine Learning Algorithms
Authors: Lokanan Mark
Published: April 2023

The ease with which mobile money is used to facilitate cross-border
payments presents a global threat to law enforcement in the fight
against laundering and terrorist financing. This paper aims to use
machine learning classifiers to predict transactions flagged as a fraud
in mobile money transfers. Data for this paper came from real-time
transactions that stimulate a  well-known mobile transfer fraud scheme.
This paper uses logistic regression as the baseline model and compares
it with ensembles and gradient descent models. The results indicate that
the established logistic regression model did not perform too poorly
compared to the other models. The random forest classifier had the most
outstanding performance among all measures. The amount of money
transferred was the top feature to predict money laundering transactions
through mobile money transfers. These findings suggest that more
research is needed to improve the logistic regression model. The random
forest classifier should be further explored as a potential tool for law
enforcement and financial institutions to detect money laundering
activities in mobile money transfers.
Coordination and optimization control of hybrid microgrid based on layered event triggering
Authors: Yuehua Huang , YIMING LI
Published: April 2023

In the centralized communication and distributed control of hybrid
microgrid, a hierarchical event triggering control strategy with the
participation of the microgrid central control (MGCC) is presented to
solve the problem that the control method depends heavily on the
communication network. It can effectively reduce the communication load
of the distributed cluster and ensure the reliability of the power
network. This strategy divides the control system of the hybrid
microgrid into two layers, the bottom layer is the local control layer,
which uses distributed collaborative control. The local controller
collects data information from adjacent measurement units, controls
update output status in place, and achieves the distributed autonomous
operation of the hybrid microgrid. In addition, an event triggering
strategy is introduced in the upper control layer of the microgrid,
which coordinates MGCC to obtain global information of the hybrid
microgrid, thereby issuing predefined control instructions to local
controllers to achieve flexible dispatch of the hybrid microgrid,
especially in response to power grid emergencies. Finally, the hybrid
microgrid model is built using MATLAB and simulated to verify the
effectiveness of the proposed control strategy.
Tracking control for networked control systems with DoS attacks via reinforcement learning method
Authors: Liu Jinliang , Dong Yanhui , Zha Lijuan , Xie Xiangpeng , Tian Engang
Published: April 2023

This paper is concerned with the tracking control problem for a class of
networked systems subject to denial-of-service (DoS) attacks using
reinforcement learning methods. Taking the effects of DoS attacks into
consideration, a novel value function is proposed, which considers the
cost of the control input, external disturbance and tracking error.
Then, using the structure of the value function, the tracking Bellman
equation and Hamilton function are defined. By employing the Bellman
optimality theory, the optimal control strategy and the game algebraic
Riccati equation (GARE) are solved with the Hamilton function. Next, the
desired tracking performance is guaranteed as the solution of the GARE
is found. Furthermore, an attacks-based Q-learning algorithm is
projected to find the solution to the optimal tracking problem without
the system dynamics and the convergence of the Q-learning algorithm is
given. Finally, the F-404 aircraft engine system is given to verify the
effectiveness of the proposed control strategy.
Next-Gen Biotherapeutics: A Systematic Review and Network Meta-Analysis on Postbiotics as Treatment For Pediatric Atopic Dermatitis
Authors: Sajo Ma. Easter Joy V. , Tan-Lim Carol Stephanie , Orteza Khianne Ed Miguel P. , Fernandez Patricia Barbara A. , Vila Ma. Junella C.
Published: April 2023

Background: Due to the recency of the postbiotic field, there
are no head-to-head postbiotic studies investigating its biotherapeutic
potential for atopic dermatitis (AD). No network meta-analysis (NMA) has
yet been conducted to synthesize relevant studies to compare postbiotic
interventions for AD. Objective: To assess the comparative
efficacy and safety of postbiotic strains for treating pediatric AD.
Methodology: This is an NMA of randomized controlled studies
that evaluate postbiotics in treating pediatric AD. Systematic search of
databases and registers from inception to November 30, 2022. Three
authors independently performed the search, screening, appraisal using
the Cochrane risk of bias tool version 2 and data extraction. Data
analysis was done using STATA14 software. Results: There were 9
studies that evaluated 8 postbiotic preparations. Lactobacillus
rhamnosus IDCC 3201 (LR) ranked highest in the efficacy outcome.
Compared to placebo, LR may be effective in reducing symptoms of atopic
dermatitis both in the main analysis (SMD -0.53, 95%CI -1.02 to -0.04)
and sensitivity analysis involving studies that used SCORAD (MD -5.52,
95% CI -10.46 to -0.58), based on low-certainty evidence. Based on
moderate-certainty evidence, LR probably does not increase the risk of
adverse events (RR 0.97, 95% CI 0.79 to 1.21). Although
Lactobacillus paracasei GM080 (LP2) ranked highest in the safety
outcome, it may not reduce AD symptoms compared to placebo (SMD -0.03,
95% CI -0.37 to 0.32) based on low-certainty evidence.
Conclusion: LR showed significant benefits for children with
AD, based on low-certainty evidence. Further investigation on LR is
recommended.

Published: April 2023

Recently, some studies demonstrated the association between reactivation
of Cytomegalovirus and increase of morbi-mortality in immunocompetent
patients admitted to ICUs. To determine the associated factors and
consequences of CMV reactivation among Moroccan patients hospitalized in
a medical ICU, a prospective and monocentric study was carried out on 72
immunocompetent CMV-seropositive patients admitted to the Medical ICU.
The monitoring of CMV by PCR in plasma was carried out at admission and
then weekly. The CMV reactivation was occurred in 25 (34.7%) patients.
Age of patients (37.7 vs 49.4, p=0.001), median duration of
hospitalization before ICU admission (1 vs 4, p=0.006), lower
lymphocyte count (1452.98 vs 992.4, p=0.019), increased urea (4.8
vs 13.1, p=0.001) levels and use of oxygen therapy (15 vs 16,
p=0.009) were significantly more observed in patients with CMV
reactivation upon admission. In term of consequence, the patients with
CMV reactivation had a significantly longer length of stay (15 vs 18,
p=0.002). In these patients, a last CMV viral load ≥ 3 Log IU/ml
is associated with increased risks of mortality. These results
demonstrated the association of CMV reactivation with increased
morbidity in immunocompetent patients hospitalized in a medical ICU.
Hybrid Gray Wolf Optimization Method in Support Vector Regression Framework for Highly Precise Prediction of Remaining Useful Life of Lithium-ion Batteries
Authors: Zhang Mengyun , Wang Shunli , Xie Yanxin , Yang Xiao , Hao Xueyi , Fernandez Carlos
Published: April 2023

The prediction of remaining useful life (RUL) of lithium-ion batteries
takes a critical effect in the battery management system, and precise
prediction of RUL guarantees the secure and reliable functioning of
batteries. For the difficult problem of selecting the parameter kernel
of the training data set of the RUL prediction model constructed based
on the support vector regression model, an intelligent gray wolf
optimization algorithm is introduced for optimization, and owing to the
premature stagnation and multiple susceptibility to local optimum
problems of the gray wolf algorithm, a differential evolution strategy
is introduced to propose a hybrid gray wolf optimization algorithm based
on differential evolution to enhance the original gray wolf
optimization. The variance and choice operators of differential
evolution are designed to sustaining the diversity of stocks, and then
their crossover operations and selection operators are made to carry out
global search to enhance the prediction of the model and realize exact
forecast of the remaining lifetime. Experiments on the NASA lithium-ion
battery dataset demonstrate the effectiveness of the proposed RUL
prediction method. Empirical tests demonstrate that the maximum average
absolute value error of the prediction of the fusion algorithm on the
battery dataset is limited to within 1%, which reflects the high
accuracy prediction capability and strong robustness.
Enhancing Drug-Drug Interaction Prediction by Integrating Physiologically-Based Pharmacokinetic Model with Fraction Metabolized by CYP3A4
Authors: Jiang Pin , Chen Tao , Chu Lin-Feng , Xu Ren-peng , Gao Jin-Ting , Wang Li , Liu Qiang , Tang Lily , Wan Hong , Li Ming , Hong-can Ren
Published: April 2023

ABSTRACT BACKGROUND AND PURPOSE Enhancing the precision of drug-drug
interaction (DDI) prediction is essential for mitigating potential drug
interactions and enhancing drug safety and efficacy. This study aims to
investigate the impact of in vitro and in silico approaches for
calculating the fraction metabolized by CY3A4 (fm) on DDI prediction
accuracy and identified the most effective method for improving DDI
prediction using physiologically based pharmacokinetic (PBPK) models.
EXPERIMENTAL APPROACH Both in vitro and in silico methods were utilized
to determine fm values for 33 approved drugs, or fm values were assumed
to be 100%. These fm values were then integrated into PBPK models.
Subsequently, the PBPK models were combined with a PBPK model of
ketoconazole to predict potential DDIs. Finally, the accuracy of these
predictions was assessed. KEY RESULTS The integration of in vitro fm had
remarkable precision in predicting CmaxR of 31 drugs and accurately
predicting AUCRs of 28 drugs out of 33 drugs, both within 2 times of the
measured values. However, using 100% fm and in silico fm resulted in
lower prediction accuracy that was comparable to each other. CONCLUSIONS
AND IMPLICATIONS Our study highlights the importance of incorporating in
vitro fm data into PBPK models to improve the accuracy of predicting
DDIs. While in silico fm may have some potential, its influence on
predictions appears to be limited. Additionally, our findings suggest
that drugs with high Clliver levels (>15 L·h-1) and high fm
(>75%) are particularly susceptible to the impact of
CYP3A4 inhibitor ketoconazole.
Expansion rebound deformation of clear aligners and its biomechanical influence: a three-dimensional morphologic analysis and finite element analysis study
Authors: Mao Bochun , Tian Yajing , Li Jing , Zhou Yanheng
Published: April 2023

Objectives

To determine the expansion rebound deformation (ERD) of clear aligners (CAs) and its biomechanical influence.

Materials and Methods

A four-premolar extraction treatment plan was carried out for a patient with 2 CA companies. Thirty-six digitally scanned clear aligners with the corresponding 36 virtually constructed “ideal” aligners were constructed. The arch width and length between pairs of reference landmarks of the scanned CAs and corresponding dentition models were measured. Cone-beam computed tomography data and digital dental models were used for three-dimensional (3D) finite element analysis (FEA) modeling. Thirty-six scanned CA models with the corresponding 36 ideal CA models were constructed. One-way analysis of variance was used to determine the differences among deviation values at tooth level, and paired t-test was used to compare the displacements of teeth between the two group of CAs.

Results

All CAs were wider and shorter than the digital model from which they were constructed. In the scanned CA model group, significant stress was observed in the buccolingual area of the periodontal ligament on posterior teeth, and the corresponding displacements of teeth were also noted. Significantly larger coronal displacements were noted for the lateral incisor, the canine, the second premolar, and the first molar in the scanned CA group (P < .05).

Conclusions

The general trend of ERD of thermoformed CAs was shown. This deformation may cause unforeseen tooth movements and negatively affect treatment outcomes.

Chemical education laboratories have a higher risk of work accidents than laboratories for industrial activities. Many work accidents occur in chemical laboratories. Two factors that cause work accidents are unsafe behavior and unsafe conditions. Occupational safety and health in the laboratory are crucial to creating a comfortable, safe work environment to prevent or minimize workplace accidents. This study aims to produce a handbook of occupational safety and health in chemical laboratories as a guiding supplement for chemistry practicum to create occupational safety and health in chemical laboratories. This research is a research and development (r&d) with a 4-d development model consisting of 4 main stages: define, design, develop and disseminate. Research is limited to the development stage, which ends with a practicality test. Based on expert judgment, it was found that the occupational safety and health handbook in the chemical laboratory are very valid in terms of content (3.9), language (4.0), and media (4.0), from a maximum score of 4. From the readability test, all respondents obtained students understand the content or information presented in the chemical laboratory's occupational health and safety handbook. Furthermore, through the practicality test, it was obtained that lecturers, laboratory assistants, and students gave an assessment that the occupational safety and health handbook in the chemical laboratory each scored 4.0 and 3.9, which means it is very practical. This research concludes that the chemical laboratory's occupational safety and health guidebook as a guiding supplement for chemistry practicum is valid to be implemented from the aspect of content, language, media, and readability and is very practical in its use.

Published: April 2023

Bertambahnya jumlah penduduk di kota Padang mengakibatkan kebutuhan lahan di kota Padang semakin meningkat dan berdampak pada pembangunan. Hal ini menyebabkan daerah resapan air hujan di kota Padang sangat sulit ditemukan, karena banyak lahan hijau telah beralih fungsi menjadi kawasan permukiman hingga areal pertokoan dan pusat-pusat perkantoran. Penelitian ini dilakukan  bertujuan untuk mengungkapkan seberapa besar pengaruh permeabilitas tanah terhadap laju infiltrasi di daerah pengembangan permukiman kota Padang. Penelitian ini merupakan penelitian kuantitatif dengan pendekatan korelasional. Data yang digunakan berupa data primer  yang didapatkan langsung dilapangan berupa data nilai laju infiltrasi dengan menggunakan alat Turf-Tec Infiltrometer, dan didapatkan dari pengukuran di Laboratorium  berupa data nilai gradasi butiran (tekstur tanah) yang hasilnya didapatkan dari uji saringan (ayakan) dan uji hidrometer, serta data nilai permeabilitas dengan menggunakan alat permeameter. Sedangkan data sekunder didapatkan pada literatur atau arsip pemerintahan. Berdasarkan hasil uji permeabilitas tanah dan uji infiltrasi, diperoleh hasil bahwa tidak ada hubungan (tidak berkorelasi) antara permeabilitas tanah dan laju infiltrasi pada daerah pengembangan permukiman di kota Padang. Sedangkan  permeabilitas tanah hanya berpengaruh sebesar 4,9 % terhadap laju infiltrasi.
