Authors: Setyorini Dini , Rosmita Rosmita
Published: April 2021

Surat adalah sebuah alat komunikasi tertulis yang digunakan oleh pengirim untuk mengirimkan berita atau informasi kepada penerima. Surat juga memiliki fungsi dokumentasi yang berisi rekaman tentang aktivitas suatu instansi. Surat pula dapat dijadikan sebuah bukti atau dasar untuk melakukan tindakan tertentu karena memiliki tanda keabsahan perintah yang kuat, yaitu tanda tangan pembuatnya.

Masalah dari penelitian ini adalah setiap surat masuk dan keluar yang diterima oleh Sekolah Menengah Pertama Negeri 01 Cisompet, biasanya harus di disposisikan terlebih dahulu secara manual untuk arsip. Surat yang akan keluar terlebih dahulu dibuat salinan nomor. Selanjutnya di atur dalam sebuah rak. Hal ini sangat rentan dengan masalah kehilangan arsip surat dan akan menghambat usaha pencarian data. Kesulitan yang lain muncul ketika surat yang sudah lama dikeluarkan dalam beberapa tahun yang lalu dengan jenis surat yang ada sehingga ketika akan melakukan pencarian data juga akan terhambat.

Tujuan dari penelitian ini adalah memudahkan solusi bagaimana surat masuk dan surat keluar pada suatu sekolah.

Hasil pembahasan dari penelitian ini adalah dengan proses terkomputerisasi, dapat mengelola data dalam jumlah yang lebih besar, dapat melakukan pengelolaan data berulang-ulang, dapat memproses data dengan cepat, memiliki tingkat ketelitian yang tinggi serta memiliki media penyimpanan file yang baik sehingga data akan mudah dicari.

Published: April 2021

In complex primary and revision total knee arthroplasty (TKA), rotating-hinge TKA (RH-TKA) prostheses play an important role. Compared to early fixed-hinge knee designs, new implants that include rotating platforms and improved hinge constructs may offer improvements in both survival and clinical outcomes. We sought to evaluate early survival following complex primary and revision TKA with a rotating-hinge knee prosthesis. We retrospectively reviewed a consecutive series of patients (n=47, 48 knees) who underwent revision TKA using an RH-TKA system. The mean age was 73 years (range, 37 – 86). The mean body mass index was 29 (range, 16.3 – 45.9) and the median ASA score was 3 (IQR, 2 – 3). As mortality was high, we performed a Kaplan-Meier analysis to evaluate survival, with death as failure. The median follow-up was 2.5 years (range, 0.07 – 9.8). Revision-free survival was 97% at a median 2.5 years of follow-up. Overall mortality was 46% (17/37) and survival free from death was 69% (49% - 82%) at a median of 2.5 years. Most reoperations were due to infection (5/12), following by wound-related complications (2/12) and hematomas (2/12). A high postoperative complication rate and mortality are evident in TKA using a hinged knee prosthesis in complex revision TKA. If the indication and surgical technique are matched to the complexity of the case, this type of implant offers a feasible salvage procedure.
Imagen y medios de comunicación. El caso de los centros hospitalarios en la prensa local
Authors: Ruiz Mora Isabel , Olmedo Salar Silvia
Published: April 2021

En la sociedad actual, las cuestiones de salud cobran cada día una mayor relevancia y los medios de comunicación no son ajenos a ello. En esta línea, partimos de la premisa que las instituciones públicas sanitarias, como son los hospitales, están abordando con una mayor intensidad estrategias comunicacionales para establecer diálogos con sus públicos. Al mismo tiempo  los medios de comunicación están otorgando una mayor cobertura al universo sanitario, pues este campo despierta un destacado interés en las audiencias. En concreto, los hospitales, por su contexto de proximidad, se convierten en un elemento de la cotidianidad sobre la que los medios pueden influir de forma decisiva en la construcción de los imaginarios colectivos. Es en este punto, donde esta investigación pretende aportar algunas claves sobre la imagen que proyectan los medios locales sobre los centros hospitalarios y de estar forma, poder constatar los perfiles que caracterizan el protagonismo del centro sanitario y su repercusión mediática, que incidirá de forma significativa en sus públicos. Para poder alcanzar estos objetivos, se utilizará la técnica del análisis de contenido en aquellos periódicos locales de mayor tirada en las capitales de provincia seleccionados para la muestra. Las conclusiones principales nos acercan a la necesidad de que sean las propias instituciones las encargadas de despertar el interés hacia las mismas, influyendo así, en la construcción de su imagen.
Multiwavelength Search and Studies of Active Galaxies and Quasars
Authors: Mickaelian Areg
Published: April 2021

The Byurakan Astrophysical Observatory (BAO) has always been one of the centres for surveys and studies of active galaxies. Here we review our search and studies of active galaxies during last 30 years using various wavelength ranges, as well as some recent related works. These projects since late 1980s were focused on multiwavelength search and studies of AGN and Starbursts (SB). 1103 blue stellar objects (BSOs) on the basis of their UV-excess were selected using Markarian Survey (First Byurakan Survey, FBS) plates and Markarian’s criteria used for the galaxies. Among many blue stars, QSOs and Seyfert galaxies were found by follow-up observations. 1577 IRAS point sources were optically identified using FBS lowdispersion spectra and many AGN, SB and high-luminosity IR galaxies (LIRG/ULIRG) were discovered. 32 extremely high IR/opt flux ratio galaxies were studies with Spitzer. 2791 ROSAT FSC sources were optically identified using Hamburg Quasar Survey (HQS) lowdispersion spectra and many AGN were discovered by follow-up observations. Fine analysis of emission line spectra was carried out using spectral line decomposition software to establish true profiles and calculate physical parameters for the emitting regions, as well as to study the spectral variability of these objects. X-ray and radio selection criteria were used to find new AGN and variable objects for further studies. We have estimated AGN content of X-ray sources as 52.9%. We have also combined IRAS PSC and FSC catalogs and compiled its extragalactic sample, which allowed us to estimate AGN content among IR sources as 23.7%. Multiwavelength approach allowed revealing many new AGN and SB and obtaining a number of interesting relations using their observational characteristics and physical properties.

Published: April 2021

Distributed Generation (DG) allocation in distribution network is an optimal choice in maximizing benefits and reducing power losses. In this paper, self-adaptive differential evolution (SaDE), an optimization approach, is used for optimal site and capacity of DG. Different types of DGs such as solar PV and wind turbine (WT) at constant and near unity power factor are integrated into the distribution system. For validation of the proposed algorithm, IEEE 33-bus, 69-bus and 119-bus radial distribution networks are considered. The results show that the proposed algorithm has the ability to find global minimum value of objective function along with the appropriate site and capacity of solar PV and WT type DG. Moreover, the results of proposed method are compared with other existing techniques in order to show its effectiveness. The comparison shows that the proposed technique has the ability to get the lowest power losses with the smallest DG size. Thus, the proposed technique has the ability to find an optimal decision vector that makes it suitable for real-time applications.

Published: April 2021

Arsenic (As) being a carcinogenic element present in drinking water in the less developed areas in the deprived countries contributes to many infectious diseases. The removal of arsenic traces from water needs to have an easy and efficient way for poor countries. Concerning this, a low-cost bio-adsorbent from Rice husk is prepared to remove arsenic from groundwater. Preparation of the absorbent is performed by crushing, sieving, washing and drying the rice husk. The Arsenic present in groundwater samples before and after treatment were tested by Arsenic kit. Batch experiments were carried out with ten contaminated samples of groundwater from Indus river origin area (Nasarpur) to investigate the influence of operating parameters such as adsorbent bed height (ABH) and initial arsenic concentration and residence time(TR) on As removal efficiency using locally fabricated adsorption column. Environmental parameters such as pH, temperature, TDS, and EC were also determined. It was observed that the highest optimized removal efficiency of 90% was achieved at ABH 30 cm: residence time, 60 minutes for feed arsenic concentration of 80 ppb samples. These results suggest that this bio-adsorbent can provide an easy, efficient, and economical method for removing As ions from effluents and water resources.
Electrophysiology study using patch clamp technique in sensory neurons

Published: April 2021

The electrophysiological and pharmacological study involving sensory and autonomic neurons enables the development of new effective agents in the treatment of neuropathic disorders, since they enable the elucidation of the mechanisms underlying the malfunction of the nervous system. In this context, the patch clamp technique increased the study of cells, providing a high-resolution method at the molecular level for observing the flow of ions through ion channels characteristic of excitable cells [1], such as the neurons.

When using different protocols with combinations of intracellular and extracellular solutions with specific pharmacological agents, this technique allows different unit and/or macroscopic records of active and passive electrical variables of cellular activity [2] that it favored the Nobel Prize in physiology or medicine to Erwin Neher and Bert Sakmann in 1991. Although the whole cell mode is the most used configuration in health-related researches, little is known in health courses. To apply this technique to neurons, it is commonly necessary to dissociate neurossomas.

Figure 01 shows sensory neurossome of the dorsal root ganglion (GRD) of rats from the bioterium of the State University of Ceará (CEUA process number 10339956-9). The process of isolating neurossomas from the intact ganglion consists of two phases: 1) Collagenase (1mg / ml for 75 min) and Trypsin + EDTA (0.25% and 0.025%, respectively, for 12 minutes); 2) Mechanical dispersion with 3 Pasteur glass pipettes with decreasing diameter (2.5 mm, 1 mm and 0.5 mm, respectively). Then, the neurossomas were plated on coverslips previously treated with poly-D-lysine maintained in supplemented DMEM and incubated at 37 °C and 5% CO2 [3].

The figure shows a neurossoma 24h after plating. This cell has approximately 25 µM in diameter, which it plays role nociception function [4]. Furthermore, the nucleus is not centralized, the cell does not have neurites. As for the micropipette, capillaries were used for micro-hematocrit without heparin (75 mm length, 1 mm inner diameter and 1.5 mm outer diameter) for making with tip resistance range from 1 and 3 MΩ after filling with the solution to compose intracellular medium [5].

In this technique, a microelectrode was micrometrically move toward until it lightly touched the plasma membrane. Then, a continuous negative pressure was applied to increase the contact of the glass with the membrane, stabilizing the seal (interaction between membrane and glass) and increasing it until its resistance reaches the order of 109 ohm (GΩ). Then, more suction was applied to cause the cell surface under the microelectrode to rupture, thus providing access to the interior of the cell, allowing excellent control of the cell membrane potential and, consequently, high-fidelity records of ionic currents that flow through ion channels present in the plasma membrane of neurossomas.

Consumer-Athlete Brand Relationship: A Qualitative Exploration of Sport Fans’ Experiences
Authors: Taniyev Olzhas , Gordon Brian S.
Published: April 2021

Athlete marketing can have profound effects on sport fans. While the affinity for superstar athletes is clear, the internalization of brand image associated with high-profile athletes has received little scholarly attention. The central aim of this exploratory study was to understand sport consumers’ perceptions of the athlete brand and its influence on their self-concept. Seventeen purposefully selected members of an athlete-centered fan club took part in semi-structured interviews. The interview data revealed the following prevalent themes: athlete brand adoption, athlete brand devotion, city identity, and community engagement. Based on the findings, meaningful interactions with consumers and altruistic actions fostered the relationship between the athlete and his followers. The present study contributed to the research concerning the emotional bond sport consumers have with athletes and evolving literature on athlete brand management.

In search of an imaginative utilitarianism: Decision-making tools for administrators and citizens in image-defining projects

Sometimes dreams become reality, but there are also many examples in which manic ideas for image-defining projects turn into fiascos. How do you find the right balance in the planning and decision-making of image-defining projects between taming manic mechanisms that cause these projects to fail and unleashing manic mechanisms that are necessary to make these projects happen? This article attempts to answer this question by exploring how the taming of mania (through welfare-economic analysis) and the unleashing of vision and ambition (through imagination) can be combined in a better way. We call this a search for an ‘imaginative utilitarianism’ and draw up three preconditions under which this approach can work: (1) more attention to incremental and less grotesque projects, (2) a different appreciation and historiography that places individuals less centrally and also appreciates what has not been built, and (3) a stronger interweaving between the design process and a welfare-economic approach.

Public value in trouble at urban projects

Manic mechanisms in all stages of the development of large, prestigious urban projects can be curbed by internal and external contradiction and control. Someone who has studied this for years is Paul Hofstra, director of the Rotterdam Court of Audit and surrounding municipalities. At the end of his term, he uses research reports to look back with us on the role played by the municipalities in major urban projects over the past twelve years. Recently, the Court of Audit published “Public value in trouble” a meta-analysis of ten years of audit of the Rotterdam municipal administration. In retrospect on the past years, four themes always came back: problems in policy design, implementation problems, internal cooperation and management and cooperation with other parties.

Difficulties on local incorporation of geo energy projects. Can soft power and localism be helpful?

Subsoil interventions in the Netherlands are crucial elements in the transition to a sustainable energy future. These subsoil interventions concern reduction of fossil energy mining, extraction of thermal energy, energy storage and CSS storage. These geo projects cause tensions. Planning under the mining law leads to local resistance, debate and often delay or cancelling of initiatives. The central characteristics of this planning are an important cause. As the transition to sustainable energy asks for more interventions in the subsoil, these tensions get problematic, and hinder the transition. In this article we investigate this problematic nature of planning under the mining law. In examples we show the problems, and accordingly we analyse them. We explore a more prominent role of local actors, using localism and soft power. With this article we want contribute to national and international discussions about the planning and governance of subsoil initiatives and strengthening of local involvement in these.

Política de gestão do medicamento no sistema de saúde português - inovação vs sustentabilidade
Authors: De Matos Andreia Afonso , Nunes Alexandre Morais
Published: April 2021

A inovação, em todos os processos de saúde, é reconhecida no mundo como uma forma de melhorar a resposta e o estado de saúde da população. Estes processos funcionam como motores do desenvolvimento, mas, no caso particular do sector do medicamento, podem pôr em risco a sustentabilidade dos sistemas públicos devido aos elevados custos. Neste artigo, se realiza um estudo do caso da reforma do sector do medicamento em Portugal com o objetivo avaliar se as medidas de gestão implementadas no sector do medicamento permitiram uma redução dos custos, sem restringir o acesso e promovendo em simultâneo a inovação farmaceutica. Como resultado da análise, verificou-se que a inovação não influenciou os custos globais com o medicamento e que o acesso melhorou, sem colocar em risco a sustentabilidade do Sistema Nacional de Saúde (SNS).

Interspecies Signaling and Habituated Conviviality1
Authors: Hendlin Yogi Hale
Published: April 2021

The conviviality of sharing habitat can lead species to learn and benefit from other species’ signals, even if those communications are not intended for them. Purposeful interspecific signaling is also common. Forms of symbiotic semiosis, intentional and unintentional, result from repeated interactions between cohabitating species. Attunement to neighboring species’ dispositions through sharing habitat carves overlapping grooves in the semiosphere predictable for organisms to make some sense of their overlapping Umwelten. Interspecies semiosis may be less generalizable than conspecific signaling, yet these interactions nonetheless can be interpreted as a form of modus vivendi ethics.

Published: April 2021

The object of this research is the analysis of the personal archives of Russian historians. The subject of this research is the examination of the personal archive of Professor Valery Ivanovich Bovykin, preserved in the Department of Manuscripts of the Russian State Library since 1998. Leaning on the aforementioned sources, the article explores the history of the project “The Fate of Russia's Debt”, which was among unaccomplished plans of the scholar. The author attempted to assess the role of V. I. Bovykin in project organization on studying Russia's debts in the early XX century. The article touches upon the topic of discovery of the scholar’s laboratory, his archive for finding new scientific historical knowledge. The author analyzes how the Professor's personal archive allows following the process of creating the project infrastructure, since all the materials on the project were accumulated by the scholar, which defines the novelty of this work. It is revealed that the project of V. I. Bovykin was against the foreign policy conducted by the Russian Federation in the 1990s. The conclusion is made that the key components of the scientific method, followed by Valery Ivanovich Bovykin in his research, imply a solid empirical base, as well as advancing the topic to the international level.
Participation of the prosecutor in consideration of civil cases by the courts of appeal
Authors: Kovalev Artem Aleksandrovich
Published: April 2021

The object of this research is the social relations that emerge in the context of participation of the prosecutor in consideration of civil cases by the courts of appeal, as well as the problematic aspects of the exercise of his powers in consideration of such cases. The author analyzes the essence of prosecutor's participation in consideration of civil cases by the courts of appeal, and the possibility of attributing such participation to one of the forms of prosecutor’s participation in consideration of civil cases by the courts. The subject of this research is the case law materials, legislative norms that regulate the indicated social relations, as well as the developed positions pertaining to the essence and separate aspects of the prosecutor's participation in consideration of civil cases by the courts of appeal. The prosecutor’s participation in the appellate instance has traditionally been the subject of research among legal scholars; this is associated to the specifics of this institution, that incorporates the elements of consideration of cases by the courts of first instance and their revision, which, in turn, generates discussions on the composition and procedure for the exercise of powers of the prosecutor participating in the appellate instance. At the same time, such research mostly dealt with participation of the prosecutor in consideration of criminal cases by the courts of appeal, while the problematic aspects of prosecutor’s participation in consideration of civil cases by the courts of appeal remained virtually unstudied, which defines the novelty of this work. The author formulates recommendations on the amendments to the current legislation on the forms of prosecutor’s participation in consideration of civil cases by the courts and the procedure for participation in consideration of civil cases by the courts of appeal, the implementation of which would allow the prosecutor’s office to achieve the goal of protection of citizens’ rights and optimization of consideration of civil cases by the courts of appeal.
Conjuring up creativity: the effect of performing magic tricks on divergent thinking
Authors: Wiseman Richard , Wiles Amy , Watt Caroline
Published: April 2021

Research suggests that learning to perform magic tricks can promote both physical and psychological wellbeing. The current study extended this work by examining the impact of learning magic tricks on divergent thinking. A group of 10- to 11-year-old children completed Guilford’s Alternate Uses Test both before and after participating in either a magic-based, or art-based, activity. As predicted, compared to the art-based activity, the magic-based activity resulted in a significantly greater increase in both AUT Fluency and AUT Originality scores. Rosenberg’s Self-Esteem Scale and Dweck’s Implicit Theories of Intelligence Scale for Children was also completed after each activity, and participants’ self-esteem scores were higher after the art-based activity than the magic-based activity. In an exploratory aspect of the study, the AUT was re-administered to both groups three weeks later, and yielded no significant differences. The practical and theoretical implications of these findings are discussed, along with recommendations for future research.

Background and Objectives: To assess whether the audiological and clinical outcomes of type 0 tympanoplasty (T0) performed using cartilage were comparable with those of ossiculoplasty in patients who underwent canal wall down mastoidectomy (CWDM).Subjects and Methods: This study included patients who had chronic otitis media with cholesteatoma and underwent CWDM with ossiculoplasty involving partial ossicular replacement prosthesis (PORP), total ossicular replacement prosthesis (TORP), or T0. Anatomical success rates and hearing outcomes were analyzed.Results: Seventy-two patients were included in this study; 29 of them underwent CWDM with T0, 27 underwent CWDM with PORP, while 16 underwent CWDM with TORP. The difference in mean improvement in the air-bone gap (ABG) between the groups was not significant. The differences in the rates of ABG closure to ≤10 dB HL (p=0.030) and ≤20 dB HL (p=0.029) were significant. There were significant differences in improvements in the ABG at 3 kHz among the PORP, TORP, and T0 groups.Conclusions: The audiological outcomes of CWDM with ossiculoplasty seemed to be better than those of CWDM with T0 with no significant difference in the incidence of complications following ossiculoplasty and T0.
Exploring Intracellular Ion Pools in Coccolithophores Using Live‐Cell Imaging

Some microorganisms, such as coccolithophores, produce an intricate exoskeleton made of inorganic solids. Coccoliths, the calcium carbonate scales of coccolithophores, are examples of the precise bioproduction of such complex 3D structures. However, the understanding of the cellular mechanisms that control mineral formation inside the cell, specifically the ability of these microalgae to transport high fluxes of inorganic building blocks, is still limited. Recently, using cryo‐electron and X‐ray microscopy, several intracellular compartments are shown to store high concentrations of calcium and phosphorous and are suggested to have a dominant role in the intracellular mineralization pathway. Here, live‐cell confocal microscopy and fluorescent markers are used to examine the dynamics of ion stores in coccolithophores. Using calcein and 4′,6‐diamidino‐2‐phenylindole (DAPI) as fluorescent proxies for calcium and polyphosphates, the experiments reveal an unexpected plethora of organelles with distinct fluorescent signatures over a wide range of strains and conditions. Surprisingly, the fluorescent labeling does not show changes along the calcification process and is similar between calcifying and noncalcifying cells, suggesting that these ion pools may not be a dynamic avenue for calcium transport. In such a case, the enigma behind the ability of coccolithophores to sustain intracellular calcification still awaits comprehensive elucidation.

Fibrinolytic drugs have been successfully used to manage acute thrombotic and thromboembolic conditions. However, their narrow administration time window, rapid clearance, and possible inactivation limit their efficient and wider application. Most importantly, they present a substantial risk of fatal bleeding complications, which are a major cause of mortality and morbidity. Improving the therapeutic outcomes of pharmacological thrombolysis, including alleviating associated side effects, is an urgent challenge. In this context, nano‐drug delivery systems have attracted major interest. State‐of‐the‐art nanodelivery systems have achieved reduced immunogenicity and a significant prolongation of the biological half‐life of drugs, the latter allowing their application as boli instead of infusions. Recent research focuses on theranostic systems capable of image‐guided thrombolysis, clot targeting strategies, and stimuli‐responsive systems. The latter are designed so that an external or internal stimulus triggers the drug release, offering unique spatiotemporal control over the treatment and potentially minimizing side effects. In this review, the authors discuss the different nanodelivery platforms and focus on stimuli‐responsive systems, highlighting their therapeutic advantages and the challenges for their clinical translation.

The thermoelectric material ZnSb utilizes elements that are inexpensive, abundant, and viable for mass production. While a high thermoelectric figure of merit zT, is difficult to achieve in Sn‐doped ZnSb, it is shown that this obstacle is primarily due to shortcomings in reaching high enough carrier concentrations. Sn‐doped samples prepared in different equilibrium phase spaces in the ternary Zn‐Sb‐Sn system are investigated using phase boundary mapping, and a range of achievable carrier concentrations is found in the doped samples. The sample with the highest zT in this study, which is obtained with a carrier concentration of 2 × 1019 cm−3 when the material is in equilibrium with Zn4Sb3 and Sn, confirms that the doping efficiency can be controlled by preparing the doped sample in a particular region of the thermodynamic phase diagram. Moreover, density functional theory calculations suggest that the doping efficiency is limited by the solubility of Sn in ZnSb, as opposed to compensation from native defects. Cognizance of thermodynamic conditions is therefore crucial for rationally tuning the carrier concentration, a quantity that is significant for many areas of semiconductor technologies.

Dryland wheat production potential in the northern Great Plains (NGP) often is limited by N availability affected by various management practices. A 4‐yr study was conducted in northeast Montana to relate spring wheat (Triticum aestivum L.) productivity and N utilization to management system (conventional and ecological), tillage (till and no‐till), and four crop rotations (continuous spring wheat, spring wheat–pea [Pisum sativum L.], spring wheat–hay barley [Hordeum vulgare L.]–pea, and spring wheat–hay barley–corn [Zea mays L.]–pea). Ecological management included greater seeding rates, delayed planting dates, banded N fertilizer, and increased stubble height compared with conventional management with standard seeding rates and planting dates, short stubble height, and broadcast N fertilizer. Continuous spring wheat showed the lowest grain yield, with the least efficient utilization of N compared with 2‐, 3‐, and 4‐yr rotations. Mineral nitrogen use efficiency was 37% lower for continuous wheat than for other rotations. Increasing the complexity of crop rotation had little impact on wheat production or N relationships. The delayed planting date associated with ecological management of spring wheat contributed to 33% less efficient use of N compared with an early planting date with conventional management. Overall, results indicated that crop rotation and management system often affected N relationships with wheat production, whereas the effects of tillage differed with year. Differences in yield and N use of spring wheat varied among years, underscoring the need to refine management systems given the highly variable precipitation patterns typical of the NGP.

Neurodevelopmental diseases are increasingly recognized to be caused by “de novo” variants with the expanding use of next‐generation sequencing. The apparent de novo variants may actually be low‐level hereditary parental mosaic variants, which could increase the recurrence risk of disease by >50% and is thought to be an underappreciated cause of neurodevelopmental diseases. Our study aimed to investigate the frequency of parental mosaicism in “de novo” neurodevelopmental diseases. A total of 237 patients (and parents) with neurodevelopmental diseases carrying apparent de novo pathogenic or likely pathogenic variants were recruited consecutively. Deep next‐generation sequencing was performed on parental samples to identify parental mosaicism. Fourteen parental disease‐causing mosaicism variants (3.0%) in 11 genes were detected with alternate allele frequency (AAF) 0.22%–34%. Three parents showed milder clinical phenotypes than their offspring with relatively high AAF (23.33%, 25%, 34% separately). One recurrent variant was identified prenatally. A review of cohort study on parental mosaicism in neurodevelopmental diseases was performed. Our study highlights that identifying the parental mosaic disease‐causing variants especially the low‐level mosaicism will contribute to improving the accuracy of genetic counseling and prenatal diagnosis for reproductive risks.

Cyclohexanone‐formaldehyde resin and acetophenone‐formaldehyde resin were in situ modified with sodium alendronate and the nanocomposites of cyclohexanone‐formaldehyde resin with sepiolite and montmorillonite by adding the nanoclay into the resin formation media. The analysis of nanocomposites of nanoclay in the resin were carried out with X‐ray diffraction. Exfoliated nanocomposites containing as much as 5 wt% sepiolite were obtained while the nanocomposites of montmorillonite were intercalated. The nanocomposites of alendronic acid‐modified ketone‐formaldehyde resin containing as much as 20 wt% sepiolite or 10 wt% montmorillonite were successfully produced in situ. Fourier transform infrared and nuclear magnetic resonance spectroscopies (NMR) were used for the structural characterization of the modified resins. The alendronic acid modified resins and their nanocomposites with the clays were used to produce reactive non‐toxic fire retardant rigid polyurethane foam. The polyurethane foam containing alendronic acid‐modified acetophenone‐formaldehyde resin had a residue of 20% in the thermogravimetric analysis and was HB‐grade in the horizontal fire test (HB) and self‐extinguished in about 3–5 s during the test. Polyurethane foams containing alendronic acid and the nanoclay with the limiting oxygen index value of 20.8 were achieved.
