Authors: Abhishek Mehta
Published: August 2022

World Health Organization (WHO) in the year 2007 recognized the growing burden of oral diseases worldwide and emphasized the need to scale up action based on comprehensive data collection systems. In view of the global epidemic of untreated caries in children there is an urgent need to establish a scoring system that both assesses and quantifies various advanced stages of caries. Furthermore, the available data are not readily comparable due to the different scoring systems used. The DMF index despite having limitations has been widely utilized in oral epidemiological surveys. It is recommended by the WHO for measuring and comparing the experience of dental caries in populations. The path of future research in caries epidemiology will depend on finding an ideal caries index. Objective: This review is prepared to present and critically evaluate various new caries assessment systems that have been developed in the last decade. Literature review: A literature search was done to find out major caries assessment systems developed over last decade, it revealed there were five new indices developed to assess caries. These indices were critically evaluated to list their strengths and limitations. Conclusion: There are many promising new caries indices purposed, but still there is a need for further studies to evaluate their validity and reliability before they can replace DMFT index.

Published: August 2022

The posterior urethral valve (PUV) is one of the main causes of congenital obstruction
of the lower urinary tract in pediatrics. Its occurrence, although rare, can cause
chronic kidney disease (CKD), with frequent progression to end stage kidney disease.
Therefore, the development of new diagnostic strategies, such as biomarkers, is crucial to
better assess the prognosis of patients with PUV. We aimed to review the literature on traditional
and new biomarkers in PUV. For that, searches were performed in
PubMed/MEDLINE, Scopus and SciELO databases. To systematize the search, terms
such as “Posterior Urethral Valve”, “Prognosis”, “Biomarkers” and variations described
in the Medical Subject Headings (MeSH) database were used. The literature showed new
biomarkers of disease prognosis, with emphasis on inflammatory cytokines, proteomics
and genomics techniques, as well as classic biomarkers, focusing on serum creatinine
and urine osmolality. As for biomarkers recently described in the literature, the 12PUV, a
set of 12 fetal urinary peptides that accurately predicted postnatal kidney function in fetuses
with PUV, stands out. Similarly, oxidative stress markers, inflammatory cytokines
and components of the renin-angiotensin system (RAS), when increased, were indicative
of severe kidney outcomes. Genetic alterations also correlated to worse prognosis among
patients with PUV, with emphasis on RAS polymorphisms and, specifically, those affecting
the angiotensin-converting enzyme (ACE) and the angiotensin II receptors types 1
and 2 (AGTR1 and AGTR2) genes. Considering the severity of the PUV condition, the
identification of sensitive and cost-effective biomarkers, beyond improving diagnosis,
may favor the investigation of new therapeutic strategies.

Published: August 2022

The lung is exposed to various pollutants and is the primary site for the onset of various diseases, including
infections, allergies, and cancers. One possible treatment approach for such pulmonary diseases involves direct
administration of therapeutics to the lung so as to maintain the topical concentration of the drug. Particles with nanoscale
diameters tend to reach the pulmonary region. Nanoparticles (NPs) have garnered significant interest for
applications in biomedical and pharmaceutical industries because of their unique physicochemical properties and
biological activities. In this article, we describe the biological and pharmacological activities of NPs as well as summarize
their potential in the formulation of drugs employed to treat pulmonary diseases. Recent advances in the use
of NPs in inhalation chemotherapy for the treatment of lung diseases have also been highlighted.

Published: August 2022

Plants have substantial potential for the development of various biopharmaceuticals.
Plants provide a cost-effective and direct source for the production of biopharmaceuticals such as
vaccines, antibodies, proteins, enzymes, and hormones. In most cases, purification is an important
and expensive step in the production of these substances. The problem can be resolved when it is
produced in plants and the whole plant can be consumed. Direct ingestion of plant materials may
help in overcoming the purification step. Being produced in seeds, fruits and tubers, it helps in
providing more immunization in developing countries at a cheaper rate. Moreover, it can be administered
more efficiently than any other dosage forms. This review focuses on various immunization
and therapeutic products that are produced in plants along with currently available formulations
in each category.

Authors: Kukhar E. I.  , Kryuchkov S. V.
Published: August 2022

Floquet spectrum of charge carriers in a 2D-crystal with initially displaced Dirac points has been derived. The phase and amplitude dependences of the energy gap induced by elliptically polarized and bichromatic high-frequency fields has been investigated. In contrast to graphene the linearly polarized electric field has been shown to be able to transform the initially semi-metallic state of Dirac crystal into the Floquet-insulator state. The conditions for such a transition are indicated, one of which is the mismatch between the orientation of the field polarization line and the direction of the crystallographic axes. Keywords: Floquet Spectrum, Quasienergy, Dirac Crystal, Semi-Dirac Crystal, Graphene, Floquet Topological Insulator.

Published: August 2022

The ability to predict the frozen semen doses produced per ejaculate would be of considerable benefit for the management of skill, human resource, capital and time. The new computing paradigm called machine learning involves in predicting dependent variable by learning complex and non-linear relationship among independent variables. The purpose of this study is to develop prediction model using one of the conventional and machine learning modelling techniques called Multiple Linear Regression (MLR) and Artificial Neural Network (ANN) respectively. A Total of 1,57,532 ejaculates data were used for modelling. The modelling involved prediction of frozen semen doses produced per ejaculate using independent variables namely volume of ejaculate, ejaculate number, sperm concentration, initial motility and post thaw motility. Various combinations of architectural parameters were employed to explore optimum configuration for each model. The ANN (R2=90.66) modelling was observed to be efficient over MLR (R2=73.52). The root mean squared error (RMSE) value was found to be lower in ANN (33.89) when compared to MLR (57.31). Hence, the ANN modelling approach is efficient to predict frozen semen doses that could be produced per ejaculate.

Published: August 2022

The cortisol and norepinephrine from human salivary can represent psychological conditions. A portable salivary amylase monitor device (sAA) has existed; however, how the sAA corresponds to the central nervous system changes is still limited to carry out. Twenty university students aged between 20 and 22 years participated in which they played a stressful computer game during the experiment. Nineteen EEG electrodes were attached to the head scalp while the relative power on the delta, theta, alpha, and beta-band was calculated. The sAA value was obtained using a portable device called Nipro Cocorometer from Japan. The sAA levels and the brain's relative band power increased. Beta waves of the brain's right hemisphere were found higher than that of the left hemisphere, especially on the right temporal (T4, p < 0.01). Then, we concluded that the beta-band power on the right hemisphere corresponds to wthe sAA changes.
Effectiveness of Mental Health Apps for Distress during COVID-19 in U.S. Unemployed and Essential Workers: A Remote Pragmatic Clinical Trial (Preprint)
Authors: Comtois Katherine , Mata-Greve Felicia , Johnson Morgan , Pullmann Michael , Mosser Brittany , Arean Patricia
Published: August 2022

BACKGROUND

During the COVID-19 pandemic, the general public were concerned about the mental health impacts of unemployment due to COVID and the stress essential workers experienced during this time. Several reports indicated that people in distress were turning to digital technology, but there was very little evidence about the impact of these tools on mitigating distress.

OBJECTIVE

This study sought to determine the acceptability, feasibility, usability, and effectiveness of mobile mental health apps for decreasing mental health symptoms in essential workers and unemployed individuals with suicide risk.

METHODS

We recruited participants who indicated that they were unemployed because of COVID-19 or were COVID-19 designated essential workers. Participants were randomized to one of four free commercial mobile applications for managing distress that were (1) highly rated by PsyberGuide and (2) met criteria for intervention features these participants indicated were desirable in a previous survey. Participants used the apps for 4 weeks and completed baseline and 4-weeks self-assessments of depression, anxiety emotional regulation and suicide risk.

RESULTS

We found no differences between the apps in any outcome but did find significant changes in depression and anxiety over time (PHQ9: estimate= -1.5, SE 0.2, 95% CI -1.1--1.8; P < .001; GAD-7: estimate= -1.3, SE 0.2; 95% CI -1.0--1.6; P < .001). We found no significant changes in suicidal behavior (SBQ-R) or emotional regulation (DERS-SF) for the 4 weeks. We did find a significant dose-response pattern for changes in depression and anxiety. Using the app at least once a week resulted in greater improvements in treatment conditions over time on depression (estimate = -0.6; SE 0.2; 95% CI 1.0--0.2; P = .003) and anxiety (estimate= 0.1; SE 0.2; 95% CI 0.4-0.6; P = .78). There was no association between app frequency and changes in suicidal behavior (SBQ-R) or emotional regulation (DERS-SF). We further found a significant difference between the conditions with regard to app usability, with the control app being the most usable (mean(Beautiful Mood) 72.9, SD 16.7; mean(Covid Coach) 71.2, SD 15.4; mean(Calm) 66.8, SD 17.3; mean(7 Cups) 65.2, SD 17.7). We found no significant differences on app acceptability or appropriateness.

CONCLUSIONS

Few studies evaluate prospectively the utility and usability of commercial apps for mood. This study finds that free, self-guided commercial mobile mental health apps are seen as usable, but no one app is superior to the other. Although we found that regular use is indicated for effects on depression and anxiety to occur in those who are more symptomatic, regression to the mean cannot be ruled out.

Holistic Consciousness in Chicana Feminist Thought
Authors: Chtioui Nadia
Published: August 2022

As Holism has evolved as a new area of perception, analysis and approach different sets of disciplines become involved in it to come up with new visions and thoughts. In this realm, feminist studies with their various tendencies and concerns share certain principles, yet they differ in others. Chicana feminism, as the construction of feminist aims of the Mexican American women, embraces new concepts and views towards the assertion of the colored woman identity who is different from the white/Anglo American woman. The call for the building up of such a consciousness carries within much cultural heritage. Within this spectrum lies our interest in Chicana consciousness that connects folklore, myth, spiritualism and folk belief. The underlying of such a thought embraces a holistic consciousness that lies within Chicana thought and writings. Along this paper, I am going to unfold the aspects of this holistic phenomenon in Chicana feminism through some examples of Chicana writings. Through the analysis of some examples of Gloria Anzaldua’s Borderlands/La Frontera as well as other Chicana feminist writers and thinkers I will use a feminist perspective that will reveal this holistic feminist consciousness more clearly. My aims, by the end of this scrutiny, are to come up to the conclusion that the holistic consciousness inherent in the Chicana writings and thought has to address the white Anglo American society and to deconstruct it from within. Chicana feminism is in itself a resistance tool against the mainstream culture and the Western ideals.

Published: August 2022

Purpose:
To evaluate the cost–effectiveness of atezolizumab plus chemotherapy as first-line treatment for metastatic urothelial cancer (mUC).
Materials & methods:
A Markov model was established for the analysis. Parametric survival models were used to fit to progression-free survival and overall survival data in the IMvigor130 study. A series of one-way and probabilistic sensitivity analyses were performed to test the robustness of the model.
Results:
The incremental cost–effectiveness ratios for atezolizumab plus chemotherapy versus chemotherapy alone were US$475,633.17 and $207,488.17 per quality-adjusted life year in the USA and China, respectively. Utility for the progression-free survival and progressive disease states, the cost of atezolizumab had the most significant impact on the incremental cost–effectiveness ratio.
Conclusion:
Atezolizumab plus chemotherapy is not a cost–effective treatment option as a first-line treatment for metastatic urothelial cancer.
The triple junction of the North America, Cocos, and Caribbean plates. What we know, what we don’t
Authors: Guzmán-Speziale Marco
Published: August 2022

We present a summary of the tectonic elements of the North America-Caribbean-Cocos triple junction area. In the vicinity of the triple junction, displacement related to the North America-Caribbean plate boundary takes place along the left-lateral Motagua-Polochic fault system, and convergence between the Cocos and the other two plates occurs along the Middle America trench.

The trace of the Motagua-Polochic system is lost at its westernmost end and does not reach the convergent boundary. Deformation of the plate boundary in this location is then distributed along a system of reverse faults (the Reverse-faults tectonic province), a system of left-lateral faults (Strike-slip faults province), two or more large NW-SE oriented left-lateral faults (Angostura and Concordia faults), and a left-lateral fault (Tonalá) that might be construed as the continuation of the Polochic fault along the southern border of the Chiapas Massif.

Somewhere within this deformation zone, transition in overriding plate between North America and Caribbean takes place, but it is not clear exactly where. It is probably at about longitude 96° W because both the dip and the shape of the subducted Cocos slab change significantly at this longitude.

Published: August 2022

Abstract: Untreated diabetic retinopathy, a condition brought on by unmanaged chronic diabetes, can result in total blindness. In order to avoid the serious side effects of diabetic retinopathy, early medical diagnosis of diabetic retinopathy and its medical treatment are imperative. Ophthalmologists must spend a lot of time manually diagnosing diabetic retinopathy, and patients must endure a lot of discomfort throughout this process. With the use of an automated technology, we can rapidly identify diabetic retinopathy and conveniently continue treatment to prevent further damage to the eye. Exudates, haemorrhages, and micro aneurysms are three features that this study suggests extracting using machine learning. These features are then classified using a hybrid classifier, which combines support vector machines, k nearest neighbours, random forests.

Published: August 2022

Abstract: Massive Road building and development is being taken up in India, under various schemes, such as National Highway Development Project (NHDP) and Prime Minister’s Rural Road Development Schemes (PMGSY). Activities of improvement of about 45,000 kms of National Highways and around 400,000 kms of rural roads besides numerous urban roads are going on, all across the country. To ensure safety of all, there is a need to adopt an efficient and effective plan for management of traffic in work zones which are already blackspots. Work Zone Traffic Management Plans (WTMPs) are required to meet the safety needs of regular traffic as well as works traffic, ensuring minimum disruption in access to properties and movement of pedestrians. This research is a case study of road accident scenario on NH-152(Ambala-Zirakpur section). In 28.05 kilometers long stretch it has 24 identified accidental black spots, indicates that about 12-13 km of the road length has engineering faults and lack adequate infrastructure as per the requirements of the vehicles/pedestrians. This research talk about management of activities involved during its blackspot rectification work in work zone areas. As per this approach we have divided whole stretch into 5 corridors and described management of activities with main concern of safety, cost and time. At last, we have compared traditional approach of blackspot improvement and corridor approach of black spot improvement and finally concluded our study in form of guidelines which can be adopted during black spot rectification using corridor approach.

We analyzed the structural relationship between social support, reflective thinking, and teacher efficacy by applying a structural equation model. The bootstrapping was conducted to verify the significance of the mediating effect.
Results As a result of analyzing the structural relationship between social support, reflective thinking, and teacher efficacy, it was found that social support had a positive effect on reflective thinking and teacher efficacy, respectively, and reflective thinking had a positive effect on teacher efficacy. As a result of verifying the mediating effect of reflective thinking in the relationship between social support and teacher efficacy, it was found that reflective thinking positively mediated social support and teacher efficacy. In particular, it was found that social support had a greater indirect effect on teacher efficacy through reflective thinking than on teacher efficacy.
Conclusions The results suggest that it is necessary to establish a social support system that can activate reflective thinking in order to improve the teacher efficacy of early childhood teachers.
The Relationship between Unstable Adult Attachment and Ambivalence Over Emotional Expressiveness in College Students: The Mediating Effect of Internalized Shame

Published: August 2022

Objectives This study examines the mediating effect of internalized shame in the relationship between unstable adult attachment and ambivalence over emotional expression of college students who are in the early adulthood, who must accomplish the developmental task of ‘formation of intimacy’ in the psychosocial development stage. This study identified the process that affects the ambivalence over emotional expression according to the adult attachment type of college students. And it is expected that this study will suggest the direction of counseling and program development or psychological education intervention for college students in the future.
Methods For this study, we conducted a survey by conveniently sampling 242 college students aged 18 years or older who are currently attending or taking a leave of absence from domestic universities. We used SPSS 22.0 for the data analysis of this study, and performed frequency analysis for the demographic variables of the study subject and verification of the reliability of the scale(Cronbach'α). In addition, we conducted Pearson correlation analysis to identify the relationship between variables, and conducted three-step multiple regression analysis and sobel test to verify the mediating effect of internalized shame.
Results First, the results of analyzing the correlations between each variable of college students' unstable adult attachment, internalized shame, and ambivalence over emotional expression all showed significant positive correlations. Second, as a result of examining the mediating effect of internalized shame by classifying unstable adult attachment into sub-variables, attachment anxiety and attachment avoidance, it was partially mediated between attachment anxiety and emotional expression ambivalence. On the other hand, it completely mediated between attachment avoidance and emotional expression ambivalence.
Conclusions This study shows that college students with unstable adult attachment type are more likely to feel shame, such as incompetent or inappropriately experiencing themselves, by internalizing negative evaluations and experiences from important subjects in the past. In addition, it was shown that this again leads to psychological conflicts due to hesitation and habitual inhibition of emotional expression.

Published: August 2022

Objectives The purpose of this study is to analyze learners' perceptions and necessity of the university liberal arts curriculum at the time when the government's COVID-19 prevention policy was in full swing. For this purpose, 475 students taking liberal arts courses at A Univ. located in the metropolitan area were evaluated on their experiences of taking liberal arts courses, awareness and necessity of lecture structure, learning activities, academic achievement, academic achievement, and evaluation.
Methods As an analysis method, as a result of examining the requirement ranking by factor through the Borich’s Requirement Formula and the The Locus for Focus Model, it was found that there was a statistically significant difference in the t-test for importance and current level.
Results First, the content showing the highest trend among the teachers' requests for lesson design perceived by learners was the composition of various theoretical lectures and learning activities tailored to liberal arts subjects. Second, it is necessary for teachers to improve students' ability to solve problems and think through liberal arts classes, and to have frequent opportunities for mutual communication between professors and learners. Third, students perceived positively both at the current level and importance in relation to the liberal arts class grade evaluation. Fourth, students gave an overall positive evaluation of the current liberal arts curriculum.
Conclusions The researcher first needs to reinforce the lesson design that can communicate well with each other regardless of the type of class in order to increase the educational performance and effectiveness between professors and learners. It was suggested that universities and professors are required to prepare a standard system that can autonomously design lessons according to new lesson types and monitor learners' learning performance.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Lee Jaeho
Published: August 2022

Objectives The purpose of this study is to analyze the reading comprehension of elementary school students using the cognitive diagnosis model, centering on the G city regional children's center.
Methods The test scores of a total of 184 students who cooperated with the study through the cooperation of 40 regional children's centers in G Metropolitan City were analyzed. As a test tool, some items from the JNE Reading Ability Diagnostic Test developed by the Jeollanam-do Office of Education were used. For the analysis, the Fusion model was used among the cognitive diagnostic models, and a total of 7 cognitive factors were confirmed through the validation of the cognitive factor Q matrix.
Results We divided the group into two types, the low-achieving group in reading comprehension and the normal-achieving group in reading comprehension, and compared the difference in scores and mastery of cognitive factors according to factual comprehension, inferential comprehension, and evaluative comprehension. And as a result of performing latent hierarchical analysis using M plus version 5.21, there were clear latent hierarchies based on three levels of understanding, and about 30% of the group had difficulty in reading.
Conclusions In a study conducted assuming seven reading comprehension cognitions, it was found that the percentage of mastery of all seven cognitive elements showed the highest percentage through the item parameter estimation by the Fusion model. And the results of comparing the factual comprehension, inferential comprehension, and evaluative comprehension scores of the low-achieving reading comprehension group and the reading comprehension average-achieving group through item difficulty showed significant differences. Implications and discussions are presented through this.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kim Shinhye
Published: August 2022

Objectives The purpose of the study was to investigate Korean and native English teachers’ perceptions of online classes during the COVID-19 pandemic in terms of their technological pedagogical content knowledge (TPACK), techno-stress, teacher efficacy, and environmental support. The study also attempts to illustrate how the Korean and native English teachers have adapted to online classes during the COVID-19 pandemic and how their experience has affected their perceptions about online classes.
Methods Data were collected through a survey questionnaire and interviews. A total of 37 (27 Korean, 10 native English) faculty members responded to the questionnaire and twelve of them participated in the interview. The responses in the survey were analyzed to compare the participants’ experience in online classes and their perceptions and interviews were coded to illustrate their adaptation process of teaching online classes.
Results The results showed that there was no significant difference between the Korean and native English faculty groups in terms of their online class experience, and perception of TPACK, techno-stress, teacher efficacy, and environmental support. It was shown that the mean scores of TPACK and teacher efficacy were relatively high while their techno-stress was not high. The participants underwent the process of frustration, adaption, and reflection while coping with challenges of acquiring and utilizing technology-based instructional tools in their online classes. Though the participants were forced to adapt to online classes due to the COVID-19 pandemic, it helped them improve their technological skills and gain new understandings of their own classes and students.
Conclusions The online class experience provided the participants an opportunity to improve their TPACK and to reflect on their teaching methods, students’ perspectives, and colleagues’ support. It can be suggested that teachers need to be encouraged and challenged to adapt to new teaching environments through which they can improve their teaching efficacy.

Published: August 2022

Objectives The purpose of this study was to examine the studies on creative teaching published in Korean journals through the content analysis method and keyword network methods.
Methods TThe final 77 papers among the papers searched as keywords for ‘creative teaching’ in Korean journals were targeted. For content analysis, the 77 papers were analyzed in terms of topics and research methods using an analysis frame. In addition, 216 keywords were derived for keyword network analysis, and frequency analysis and centrality analysis were conducted using textom programs and UCINET.
Results First, before 2008 the main topic of creative teaching was creative teaching methods. From 2009 to 2014, in addition to creative teaching methods, various concepts such as creative teaching behavior, creative teaching beliefs, and creative teaching environment began to emerge, and after 2015, research on creative teaching behavior increased, and new concepts such as creative teaching competency and creative teaching efficacy were introduced. Also, from 2009 to 2104, most studies on creative teaching were conducted at universities, but after 2015, studies on creative teaching at universities and early childhood institutions increased. Second, the main keywords of creative teaching research were ‘teaching method’, ‘creative problem solving’, ‘child creativity’, and ‘teacher creativity’. As a result of network analysis, ‘creative teaching behavior’, ‘creativity’, and ‘creative teaching method’ were dominant keywords in degree centrality, closeness centrality, and mediation centrality.
Conclusions This study reviewed systematically research on creative teaching by period, and explored the relationship between the variables related to creative teaching. Implications for the results and future studies were discussed.
