Application of modified Mickens iteration procedure to a pendulum and the motion of a mass attached to a stretched elastic wire
Authors: Gholami Amin , Ganji Davood D. , Rezazadeh Hadi , Adel Waleed , Bekir Ahmet
Published: August 2021

The paper deals with the application of a strong method called the modified Mickens iteration technique which is used for solving a strongly nonlinear system. The system describes the motion of a simple mathematical pendulum with a particle attached to it through a stretched wire. This model has great applications especially in the area of nonlinear vibrations and oscillation systems. The proposed method depends on determining the frequency and amplitude of the system through the modified Mickens iterative approach which is a modification of the regular Mickens approach. The preliminaries of the proposed technique are present and the application to the model is discussed. The method depends on the Mickens iteration approach which transforms the considered equation into a linear form and then is solving this equation result in the approximate solution. Some examples are given to validate and illustrate the effectiveness and convenience of the method. These results are compared with other relative techniques from the literature in terms of finding the frequency of the two examined models. The method produces more accurate results when compared to these methods and is considered a strong candidate for solving other nonlinear problems with applications in science and engineering.
Weak and strong boundedness for p-adic fractional Hausdorff operator and its commutator
Authors: Sarfraz Naqash , Gürbüz Ferit
Published: August 2021

In this paper, the boundedness of the Hausdorff operator on weak central Morrey space is obtained. Furthermore, we investigate the weak bounds of the p-adic fractional Hausdorff operator on weighted p-adic weak Lebesgue spaces. We also obtain the sufficient condition of commutators of the p-adic fractional Hausdorff operator by taking symbol function from Lipschitz spaces. Moreover, strong type estimates for fractional Hausdorff operator and its commutator on weighted p-adic Lorentz spaces are also acquired.
Nonparametric inference for interventional effects with multiple mediators
Authors: Benkeser David , Ran Jialu
Published: August 2021

Understanding the pathways whereby an intervention has an effect on an outcome is a common scientific goal. A rich body of literature provides various decompositions of the total intervention effect into pathway-specific effects. Interventional direct and indirect effects provide one such decomposition. Existing estimators of these effects are based on parametric models with confidence interval estimation facilitated via the nonparametric bootstrap. We provide theory that allows for more flexible, possibly machine learning-based, estimation techniques to be considered. In particular, we establish weak convergence results that facilitate the construction of closed-form confidence intervals and hypothesis tests and prove multiple robustness properties of the proposed estimators. Simulations show that inference based on large-sample theory has adequate small-sample performance. Our work thus provides a means of leveraging modern statistical learning techniques in estimation of interventional mediation effects.
In silico gene knockout prediction using a hybrid of Bat algorithm and minimization of metabolic adjustment
Authors: Man Mei Yen , Mohamad Mohd Saberi , Choon Yee Wen , Ismail Mohd Arfian
Published: August 2021

Microorganisms commonly produce many high-demand industrial products like fuels, food, vitamins, and other chemicals. Microbial strains are the strains of microorganisms, which can be optimized to improve their technological properties through metabolic engineering. Metabolic engineering is the process of overcoming cellular regulation in order to achieve a desired product or to generate a new product that the host cells do not usually need to produce. The prediction of genetic manipulations such as gene knockout is part of metabolic engineering. Gene knockout can be used to optimize the microbial strains, such as to maximize the production rate of chemicals of interest. Metabolic and genetic engineering is important in producing the chemicals of interest as, without them, the product yields of many microorganisms are normally low. As a result, the aim of this paper is to propose a combination of the Bat algorithm and the minimization of metabolic adjustment (BATMOMA) to predict which genes to knock out in order to increase the succinate and lactate production rates in Escherichia coli (E. coli).

Optical data center switches design and analysis
Authors: Nigam Anjaney , Mishra Bharat , Patel Prabhat
Published: August 2021

Data centers are facing huge bottlenecks due to the emergence of high-speed data applications. To meet speed requirements, it is proposed to shift the current technologies toward optical communication-enabled data center (DC) devices. This paper discusses the recently proposed optical switch designs and proposes a novel switch design for optical DCs. The architectures proposed in the literature are compared in terms of notable parameters. Finally, proposed switch performance is measured in the network using Monte Carlo simulation and results are obtained in terms of packet loss probability, under a random traffic model while considering both nonperiodized and prioritized packets.
Novel method for trisomy 21 screening in the first trimester of pregnancy: fetal brain angle
Authors: Karslı Mehmet Fatih , Çakmak Bülent , Şen Cihat
Published: August 2021

Objectives

The present study was performed to examine the utility of a new first trimester marker called the “brain angle” (BA) in screening for trisomy 21. We postulate that differences in the midbrain anatomy between euploid fetuses and those that are affected by trisomy 21 are reflected in changes in BA measurements.

Methods

In fetuses at 11+0–13+6 weeks of gestations, which were at high risk for trisomy 21, the angle was measured between the line crossing the thalamus and mesencephalon cranial border tangentially and the line crossing the brainstem lower limit. This angle was compared between fetuses with trisomy 21 (based on karyotyping) and those with a normal karyotype.

Results

Trisomy 21 was detected in 45 (8%) of 560 fetuses. Receiver operating characteristic analysis showed that, at BA≥94°, the sensitivity and specificity for determining trisomy 21 were 97.8% (95% CI=88.2–99.9%) and 100% (95% CI=99.2–100%), respectively.

Conclusions

Fetal BA appears to be a promising new first trimester marker in screening for trisomy 21.

Lemniscate-like constants and infinite series
Authors: Campbell John M. , Chu Wenchang
Published: August 2021

We introduce lemniscate-like constants by “twisting” the standard series expansions of the classical lemniscate constants via harmonic-type factors in the summand. Closed-form evaluations for these constants are established, and are then utilized to construct alternate proofs of summation formulae obtained recently via coefficient-extraction techniques applied to Kummer’s classical hypergeometric identity.

De la Vallée Poussin inequality for impulsive differential equations
Authors: Akgöl Sibel Doğru , Özbekler Abdullah
Published: August 2021

The de la Vallée Poussin inequality is a handy tool for the investigation of disconjugacy, and hence, for the oscillation/nonoscillation of differential equations. The results in this paper are extensions of former those of Hartman and Wintner [Quart. Appl. Math. 13 (1955), 330–332] to the impulsive differential equations. Although the inequality first appeared in such an early date for ordinary differential equations, its improved version for differential equations under impulse effect never has been occurred in the literature.

In the present study, first, we state and prove a de la Vallée Poussin inequality for impulsive differential equations, then we give some corollaries on disconjugacy. We also mention some open problems and finally, present some examples that support our findings.
Effect of nanoscale dielectric environments on concentration quenching
Authors: Rout Sangeeta , Koutsares Samantha R. , Courtwright Devon , Mills Ezekiel , Shorter Ayanna , Prayakarao Srujana , Bonner Carl E. , Noginov Mikhail A.
Published: August 2021

We have studied the dependence of concentration quenching of luminescence (donor–acceptor energy transfer) on the thickness d of dye-doped polymeric films (HITC:PMMA) and found its strong inhibition at small values of d. This phenomenon is tentatively explained by a limited number of acceptors, which donors’ excitation can reach in thin samples, if the film’s thickness is comparable to the diffusion length of the energy transfer. The latter mechanism, along with effective reduction of the dye concentration, is responsible for an inhibition of the concentration quenching of dye molecules impregnating porous alumina membranes. The elongation of emission kinetics in thick (≥3 μm) HITC:PMMA films is cautiously attributed to the samples’ crystallinity.
Nanobody-targeted photodynamic therapy for the treatment of feline oral carcinoma: a step towards translation to the veterinary clinic

Published: August 2021

Nanobody-targeted photodynamic therapy (NB-PDT) has been developed as a potent and tumor-selective treatment, using nanobodies (NBs) to deliver a photosensitizer (PS) specifically to cancer cells. Upon local light application, reactive oxygen species are formed and consequent cell death occurs. NB-PDT has preclinically shown evident success and we next aim to treat cats with oral squamous cell carcinoma (OSCC), which has very limited therapeutic options and is regarded as a natural model of human head and neck SCC. Immunohistochemistry of feline OSCC tissue confirmed that the epidermal growth factor receptor (EGFR) is a relevant target with expression in cancer cells and not in the surrounding stroma. Three feline OSCC cell lines were employed together with a well-characterized human cancer cell line (HeLa), all with similar EGFR expression, and a low EGFR-expressing human cell line (MCF7), mirroring the EGFR expression level in the surrounding mucosal stroma. NBA was identified as a NB binding human and feline EGFR with comparable high affinity. This NB was developed into NiBh, a NB-PS conjugate with high PS payload able to effectively kill feline OSCC and HeLa cell lines, after illumination. Importantly, the specificity of NB-PDT was confirmed in co-cultures where only the feline OSCC cells were killed while surrounding MCF7 cells were unaffected. Altogether, NiBh can be used for NB-PDT to treat feline OSCC and further advance NB-PDT towards the human clinic.
Non-orthogonal polarization multiplexed metasurfaces for tri-channel polychromatic image displays and information encryption
Authors: Ren Renyuan , Li Zile , Deng Liangui , Shan Xin , Dai Qi , Guan Zhiqiang , Zheng Guoxing , Yu Shaohua
Published: August 2021

Interference usually occurs between two non-orthogonally polarized light beams. Hence, metasurface enabled polarization multiplexing is generally conducted under two orthogonal polarization states to realize independent intensity and/or phase modulations. Herein, we show that polarization multiplexed metasurfaces can work under three non-orthogonal polarization states to realize tri-channel image displays with independent information encoding. Specifically, enabled by orientation degeneracy, each nanostructure of the metasurface operates with triple-manipulations of light, i.e., two channels for independent intensity manipulation under π/4 and 3π/8 linearly polarized (LP) light, respectively, and one channel for phase manipulation without polarization control. We experimentally demonstrate this concept by recording one continuous-brightness polychromatic image and one binary-brightness polychromatic image right at the metasurface plane, while a continuous-brightness polychromatic image is reconstructed in the far field, corresponding to three independent channels, respectively. More interestingly, in another design strategy with separated image encoding of two wavelengths, up to six independent image-display channels can be established and information delivery becomes safer by utilizing encryption algorithms. With the features of high information capacity and high security, the proposed meta-devices can empower advanced research and applications in multi-channel image displays, orbital angular momentum multiplexing communication, information encryption, anti-counterfeiting, multifunctional integrated nano-optoelectronics, etc.

Strong-field photoemission from nanostructures and the associated temporally modulated currents play a key role in the development of ultrafast vacuum optoelectronics. Optical light fields could push their operation bandwidth into the petahertz domain. A critical aspect of their functionality in the context of applications is the impact of charge interaction effects. Here, we investigated the photoemission and photocurrents from nanometric tungsten needle tips exposed to carrier-envelope phase (CEP)-controlled few-cycle laser fields. We report a characteristic rapid increase in the intensity-rescaled cutoff energies of emitted electrons beyond a certain intensity value. By comparison with simulations, we identify this feature as the onset of charge-interaction dominated photoemission dynamics. Our results are anticipated to be relevant also for the strong-field photoemission from other nanostructures, including photoemission from plasmonic nanobowtie antennas used in CEP-detection and for PHz-scale devices.

Tailoring the physical characteristics of solution blown cellulosic nonwovens by various post-treatments
Authors: Jedvert Kerstin , Viklund Linnea , Alkhagen Mårten , Köhnke Tobias , Theliander Hans
Published: August 2021

Nonwovens are increasing in demand due to their versatility which enables use in a broad range of applications. Most nonwovens are still produced from fossil-based resources and there is thus a need to develop competitive materials from renewable feedstock. In this work, nonwovens are produced from cellulose via a direct solution blowing method. Cellulose was dissolved using the ionic liquid 1-ethyl-3-methylimidazolium acetate (EMIMAc) and was regenerated into nonwovens by coagulation in water. The properties of such nonwovens were previously rather stiff and papery-like and the aim of this work was to improve the softness and feel of the materials by simple adjustments of the post-processing steps, i. e. washing and drying. It was shown that by primarily changing the drying method, it was possible to create a much softer and bulkier material using the same solution blowing parameters.
Early Neolithic Settlement Patterns in Northern Dalmatia
Authors: Horvat Kristina
Published: August 2021

This article focuses on the early Neolithic settlement patterns in northern Dalmatia, located in the middle of the eastern Adriatic. At the present state of research, a total of 35 Neolithic sites have been known in this region, 26 of which belong to the Early Neolithic. Observing the type and character of the early Neolithic sites, their micro-topographic features, proximity and availability of resources, organization of life in relation to environment requirements, continuity of life at a particular location, and economic strategies, we come to the conclusion that the early Neolithic settlement patterns in northern Dalmatia were determined by natural landscape and its resources. They are the postulate and basis for the development of different aspects of social life and economy, as well as the starting point for the interpretation of the character and dynamics of the development of the early Neolithic communities in this area. The site locations, stratigraphic relations, and radiocarbon dating also suggest movements of the early Neolithic communities. The movements seem to have taken place exclusively within the fields. Discussion whether it was one or several simultaneous communities/settlements remains limited, since the state of research does not allow precise attribution of the site to certain chronological segments of the Early Neolithic.
Gender-based violence in higher education and research: a European perspective
Authors: Bosco Damous Licia , Guillopé Colette
Published: August 2021

The gender gap in science is intrinsically linked to gender-based violence in academia. Gender-based violence is a form of discrimination against women that occurs in an academic environment, and it often takes the form of sexual harassment. Some European countries, such as France, Italy, and Ireland, have solid legal systems in place to address sexual harassment in academia. However, as the report of the European Research Area and Innovation Committee Standing Working Group on sexual harassment points out, not all European countries have legislation in this area, or if they do, it is often ineffective. While national surveys generally show that it is difficult to prevent or combat sexual harassment in universities, practices related to corporate social responsibility could be used to start the conversation about the social responsibility of universities to fight against sexual harassment, which is reflected in this article.
Electrospinning of chitosan-based nanofibers: from design to prospective applications
Authors: Anisiei Alexandru , Oancea Florin , Marin Luminita
Published: August 2021

Chitosan is a biopolymer originating from renewable resources, with great properties which make it an attractive candidate for plenty of applications of contemporary interest. By manufacturing chitosan into nanofibers using the electrospinning method, its potential is amplified due to the enhancement of the active surface and the low preparation cost. Many attempts were made with the aim of preparing chitosan-based nanofibers with controlled morphology targeting their use for tissue engineering, wound healing, food packaging, drug delivery, air and water purification filters. This was a challenging task, which resulted in a high amount of data, sometimes with apparent contradictory results. In this light, the goal of the paper is to present the main routes reported in the literature for chitosan electrospinning, stressing the advantages and disadvantages of each of them. Special emphasis is placed on the influence of various electrospinning parameters on the morphological characteristics of the fibers and their suitability for distinct applications.

This paper is an extension of
[S. Liang,
A mechanical model of Brownian motion for one massive particle including slow light particles,
J. Stat. Phys. 170 2018, 2, 286–350].
Precisely, we consider a system of one massive particle interacting with an ideal gas,
evolved according to non-random Newton mechanical principles, via interaction potentials,
without any assumption requiring that the initial energies of the environmental particles should be
restricted to be “high enough”.
We prove that, as in the high-dimensional case,
the position/velocity process of the massive particle converges to a diffusion process
when the mass of the environmental particles converges to 0,
while the density and the velocities of them go to infinity.
Delamination properties and in situ damage monitoring of z-pinned carbon fiber/epoxy composites
Authors: Che Zhe , Wang Han , Wang Shaokai , Gu Yizhuo , Li Min
Published: August 2021

Carbon-fiber-reinforced composites with layer stacking structures are sensitive to delamination crack. To improve the interlaminar properties and further explore the capability of in situ damage monitoring of the laminate, CCF300 and CCF800 carbon fiber pins were selected to fabricate the z-pinned composites. Compared with the control sample, the G
IC values of CCF300 and CCF800 z-pinned composites are increased by 398 and 378%, respectively. This indicates that the delamination resistance improvement of the laminates is dominated by the z-pin debonding and pull-outs. The electrical resistance of the laminates was utilized to in situ monitor the crack propagation within the composite laminate. The results show that the presence of the z-pins enhances the sensitivity of damage detection. The ΔR/R
0 of CCF800 z-pinned composite is nearly three times that of the control sample at the moment the crack length reaches 110 mm. Crack length–displacement curves were obtained according to the relationship between ΔR and Δa, which clearly displayed the steady or stick-slip crack growth of the laminates with or without z-pins, respectively. Visualization of the crack growth process can provide a novel method for the delamination failure analysis of the composite.
Guided self-determination in treatment of chronic pain – a randomized, controlled trial
Authors: Pickering Anne Paarup , Bache Nina Jeanette , Estrup Stine
Published: August 2021

Objectives

To test whether Guided Self-Determination (GSD) used in chronic pain management could improve the health-related quality of life, patient activation and sense of coherence (SoC) as a measurement of life skills in patients with chronic pain. The method has been shown to be effective in other chronic conditions, but has not been tested in chronic pain.

Methods

A three-site randomised, controlled trial at three major multidisciplinary pain centres in Denmark. 200 patients were included and randomised. In the intervention period, both groups had regular visits to the pain centre with both doctors and nurses. The intervention group additionally received the GSD intervention with weekly sessions for eight weeks. Data were collected from February 2013 to July 2016 and consisted of three questionnaires answered before and after the 8-week intervention period, and after six months. The primary outcome was self-reported health related quality of life. Secondary outcomes included self-reported activation and SoC.

Results

We found no clinically relevant difference between the groups for health-related quality of life, patient activation or SoC at either baseline, at three months or at six months. We also analysed data for trends over time using mixed model analysis, and this did not show any significant differences between groups.

Conclusions

GSD did not improve health-related quality of life, patient activation or SoC when administered to patients with chronic pain treated in a multidisciplinary pain centre. New research is recommended using a combination of self-reported and objective measures and longer follow-up.
Is this really trigeminal neuralgia? Diagnostic re-evaluation of patients referred for neurosurgery
Authors: Slettebø Haldor
Published: August 2021

Objectives

Patients with facial pain are sometimes referred for neurosurgical treatment with a poorly documented diagnosis of trigeminal neuralgia. In such cases, neurosurgery will usually not be helpful. We conducted a re-evaluation of the diagnosis in patients referred for neurosurgical treatment of presumed trigeminal neuralgia. Our objective was to find out why and how often misdiagnosis occurred.

Methods

A retrospective study was done in consecutive first-time patients referred for trigeminal neuralgia to our outpatient clinic in 2019. We used five ICHD-3-based clinical criteria to verify or exclude the diagnosis. In patients where trigeminal neuralgia was excluded, we established a diagnosis for their facial pain based upon medical history and a physical examination by a neurosurgeon – often supplemented with examination by an oral surgeon.

Results

Thirty-eight patients were referred for presumed trigeminal neuralgia. Only 17 of them fulfilled the five criteria and were diagnosed with trigeminal neuralgia. In 20 of the remaining 21 patients trigeminal neuralgia could be clearly excluded, while one of the patients had a periodontitis closely mimicking trigeminal neuralgia. In 14 of the 21 patients we diagnosed temporomandibular dysfunction or dental conditions. MRI scans had detected low-grade neurovascular contacts in 13 of the 21 patients, a finding that was clearly overestimated by the referring neurologists in seven patients.

Conclusions

Overdiagnosis of trigeminal neuralgia was common in patients referred for neurosurgery, mostly due to insufficient clinical evaluation combined with an overestimation of MRI-detected NVCs. The clinical diagnosis should be critically re-evaluated before recommending neurosurgery to patients referred for presumed trigeminal neuralgia.

Pain experience was captured on the painDETECT.

Results

Eight patients presented with lumbar radicular pain only and 18 patients with combined radicular pain + radiculopathy. Patients with radicular pain only demonstrated widespread loss of function (mechanical detection) bilaterally in the MPA (p<0.003) and hand (p=0.002), increased heat sensitivity in both legs (p<0.019) and cold/heat sensitivity in the hand (p<0.024). QST measurements in the dermatome did not differ compared to HCs and patients with radiculopathy. Patients with lumbar radiculopathy were characterised by a localised loss of function in the symptomatic leg in the MPA (warm, mechanical, vibration detection, mechanical pain threshold, mechanical pain sensitivity p<0.031) and dermatome (mechanical, vibration detection p<0.001), consistent with a nerve root lesion. Pain descriptors did not differ between the two groups with the exception of numbness (p<0.001). Patients with radicular pain did not report symptoms of numbness, while 78% of patients with radiculopathy did.

Conclusions

Distinct differences in somatosensory profiles and pain experiences were demonstrated for each patient group, suggesting differing underlying pain mechanisms.
Size, allomorphy and guttural-final stems in Modern Hebrew
Authors: Faust Noam
Published: August 2021

There is a tendency for syncretism between future and infinitive stems in Modern Hebrew. Verbs with final orthographic gutturals do not follow this trend in one verbal type. In another, they do follow it, but their exponent is different from that of regular verbs. Previous studies have claimed that (i) gutturals are represented in Modern Hebrew as a vowel /a/ (Faust, Noam. 2005.The fate of gutturals in Modern Hebrew. Tel Aviv: Tel Aviv University MA Thesis); (ii) Infinitives are derived in two cycles (Faust, Noam & Vered Silber-Varod. 2014. Distributed Morphology and prosody: The case of prepositions. In Burit Melnik (ed.),Proceedings of IATL29 (MITWPL 72), 71–92. Cambridge (MA): MIT Press); and (iii) stems seek to be no shorter than two syllables (e.g. Bat-El, Outi. 2003. The fate of the consonantal root and the binyan in Optimality Theory.Recherches Linguistiques de Vincennes32. 31–60.). Relying on these claims, an analysis is proposed involving two allomorphs with a priority relation. Phonological considerations of multiple correspondence, word size and cyclicity may nevertheless override the effect of priority, leading to the selection of the non-default allomorph. In the last section I briefly discuss two alternatives to the priority relation: the autosegmental alternative and the gradient alternative.
On Choosing the Place
Authors: Malita-Król Joanna
Published: August 2021

Numerous contemporary Pagan groups conduct their ritual ceremonies outside, communing with nature. This essay describes research conducted in a small, eclectic group following the Wiccan wheel of the year in Warsaw, Poland. It focuses on the places used by the group, applying Edward Casey’s phenomenological approach to understand an encountered place, and examines what constitutes a good ritual place according to the group members. The initial supposition was that technical aspects would prevail: privacy, accessibility, and proximity of the four elements. However, the participant observation and semi-structured interviews proved that choosing the right place was primarily based on the experience and interpretation of the feeling evoked by the place: namely, whether the atmosphere was right and the entities dwelling there were seen as welcoming or not.
Killing the Competition
Authors: Introvigne Massimo
Published: August 2021

Much has been written about the South Korean government’s repression of Shincheonji after the COVID-19 epidemic, which the movement was accused of having contributed to spreading. Less attention has been paid to Shincheonji opposition that started decades before the pandemic, rooted in campaigns by the Korean Christian countercult movement aimed at eradicating “heresies” and fast-growing competitors. This article discusses the history of Christian countercultism in South Korea, the rise of Shincheonji, and why it became a main target of the countercultists who opposed the movement both through deprogramming and by calling for its suppression by the authorities. Finally, this article addresses the countercultists’ hopes that Shincheonji will disappear when its founder, believed to be immortal by devotees (based on their interpretation of the Book of Revelation), will die.
A Marginal Religion and COVID-19 in South Korea
Authors: Grisafi John G.
Published: August 2021

In the spring of 2020, South Korea became the second most infected country in the COVID-19 pandemic. The rapid spread of the virus was attributed to a Christian religious group known as Shincheonji. The association of this already controversial religion with the spread of the virus quickly led to public condemnation of the group. The public response to the group’s association with the virus was, in part, built on an existing foundation of distrust and suspicion. In this paper, I examine the details of Shincheonji’s association with the coronavirus and the public reaction to it. I show the political work done by classificatory language pertaining to religion, specifically as it influences perceptions of the legitimacy of marginal religions and how the public should treat them. I also examine how public discourses on what religion should or should not do shape the definitions and boundaries of religion and associated categories.
The Flourishing of New Religions in Korea
Authors: Introvigne Massimo
Published: August 2021

This issue of Nova Religio explores the success, in several cases spectacular, of different new religions in South Korea, and the controversies they generated. In this introduction I suggest that, notwithstanding their different Christian and non-Christian backgrounds, most Korean new religions share some common features, including messianism, millenarianism, and proposals for social reform. I introduce a typology of four major groupings: Christian new religions, “traditionalist” groups that call for a restoration of Korea’s ancient spirituality, Won Buddhism, and Jeungsanism. Finally, I suggest that both political and religious factors contributed to the flourishing of new religions in twentieth and twenty-first century Korea.
Preparing for the Confucian Millennium
Authors: Kaplan Uri
Published: August 2021

Despite its small size and unconventional doctrines, the Korean new religious movement, “Rectified Confucian Way” (Kaengjŏngyudo), exerts considerable influence on Korean society today. Members of the group operate dozens of children’s camps and other educational programs aimed to promote traditional moral behavior among the population, in line with their millennial vision of an evolving Confucian era. This article offers the first English-language introductory investigation of this fascinating movement. It reviews the early twentieth-century mystical genesis of the religion, its development of scriptures and rituals, and its members’ active, optimistic attempts to lead the world into the Confucian millennium. Based on this data, the paper suggests that this group offers a unique model of a long-term, gradualist—rather than imminent—millennial expectation.
Of God and Neighbors
Authors: Greenberger Jason Paul , Gyungwon Lee
Published: August 2021

Historically, Korea and Vietnam have been in the unenviable position of being surrounded by powerful neighbors who at times descend upon them as colonizers or occupying forces. East Asian new religious movements such as Daesoon Jinrihoe and Caodaism offer unique insights into each country’s national sentiments regarding such historicities. In particular, the painting in Daesoon Jinrihoe titled Five Immortals Playing Baduk (五仙圍碁 Oseon Wigi), and the painting in Caodaism titled The Three Saints (三聖 Tam Thánh) are strikingly similar in the manner in which both countries depict a national representative alongside foreign representatives. Generally speaking, Five Immortals Playing Baduk can be seen as providing a subtle and provocative critique of foreign interference, whereas The Three Saints has integral, reconciliatory, and diplomatic overtones. Sociological insight can be gained from analyzing the national sovereignty depicted in these paintings and related scriptural passages as a supernatural compensator as understood in Rational Choice Theory.
Rethinking Official History through Museum and Visitor Research
Authors: Marroni Cintia Velázquez
Published: August 2021

As public (state-dependent) institutions, history museums in Mexico are viewed as embodiments of official history, unable to present history as contested and constructed. This article offers a detailed explanation of how and to what extent official history operates in the construction of historical narratives and visitors’ experiences of two history museums in Mexico City. Results showed specific omission strategies, divergences, and inconsistencies in the historical discourse, as well as peoples’ autonomous and creative meaning-making of the past, both of which provide strong evidence to advocate for an understanding of official history not as one, but as several competing narratives produced at different times by institutions and professionals affiliated (either directly or indirectly) with the state.

Published: August 2021

Experimentally proved by the method of polarization resistance formation of protective layers during inhibition steel corrosion by Sulfanilamide in aqueous solutions of hydrochloric acid with different pH. It is shown the difference due to the predominance of the protonated or unprotonated form of the molecule. It was found that at predominance of protonated forms of molecules  (pH £2,4) formed dense protective films and predominance of unprotonated forms of molecules  (pH ³2,4) are formed layers that do not inhibit diffusion processes. Sulfanilamide provides high and stable inhibition efficiency (<90%) in acid chloride solutions in case of formation protective layers consisting of protonated molecules what to consider when use it.

Authors: Muchtar Masruri
Published: August 2021

Retail sukuk is a sharia product offered to Indonesian citizens as a safe and profitable investment instrument. This study identified the strengths, weaknesses, opportunities, and threats that the government may face in offering retail sovereign sukuk. It aimed to provide the government the appropriate strategies based on the historical data of listed retail sukuk and its peripherals during 2009-2020. This paper used a qualitative research approach. The data collection techniques used were literature review and in-depth interview. Internal and external factors were identified. SWOT matrix was made prior to analysis. The results show that the coupon rate offered by retail sovereign sukuk is mostly higher than BI rate. Market expansion is needed. The government shall optimize all distribution partners. Newly innovated products should be developed. Certain criteria should be formulated to determine coupon rate. This research suggests that an independent Special Purpose Vehicle should be reconstructed as a separate entity.JEL Classification: E62, G23, G28, H63How to Cite:Muchtar, M. (2021).
