Semantic Features of the Verb来 [LÁI]
Authors: Mukhamedjanova Shahbora Kamolovna
Published: February 2022

Describing the semantics of a verb is a much more difficult task. Because the content of the verb depends in many ways on its distribution. With this in mind, verbs are classified according to the direction of their meaning and the presence or absence of subject-objects with which they interact, and their number, if any. Chinese language researchers classify action verbs as part of a group of action verbs. These verbs can appear in a sentence as an independent verb predicate or as an additional part of speech as a modifier or directional morpheme. These simple verbs represent 来 [lái] to come and 去 [qù] to leave directions of action. They form compound verbs with the same meaning. The verb 来  to come is used when the action is directed to the speaker (or object), and the verb 去 to leave is used if the action is directed away from the speaker (or object). Orientation, in turn, can be set by the object or subject: when the orientation is indicated in the sentence - the object, if not specified - by the subject. Verb 来 [lái] is included in the group of basic simple action verbs in Chinese. The peculiarity of the semantics of the verb 来 [lái] to come is that it determines not only the orientation or direction of the action but also the point of the message, who (or what) describes the situation. The article examines the semantic features of the verbs of 来 [lái] directions of action. Based on the materials in Liu Shushiang’s book “现 代 汉 语 八 百 词. 吕 叔 湘” (800 words in modern Chinese), the models of 来 [lái] verbs as independent and auxiliary verbs are analyzed.

Published: February 2022

Objectives: The aim of this study was to assess the microtensile bond strength of three universal adhesives to dentin and enamel.
Materials and Methods: Sixty extracted human third molar teeth were chosen and divided into six groups regarding the adhesive (G-Premio Bond, Clearfil S3 Bond or Single Bond) and tooth surface. All the applied bonding agents were universal adhesives. The teeth were polished and the adhesives were applied; then the teeth were restored with composite resin. The samples were mounted in acrylic resin and sectioned. The specimens were subjected to a universal testing machine and the microtensile bond strength was measured. The failure mode of each specimen was determined under a stereomicroscope. Data were analyzed using two-way ANOVA (α=0.05).
Results: The microtensile bond strength of G-Premio Bond to enamel and dentin was 11.79±8.27 and 17.55±9.47 MPa, respectively which was not significantly different from the values in Single Bond group (15.59±10.66 and 17.19±10.09 MPa to enamel and dentin, respectively; P>0.05). However, the values for Clearfil S3 Bond were 7.11±4.23 and 7.88±8.83 MPa to enamel and dentin, respectively, which were significantly lower than the values for G-Premio Bond (P<0.05). Scanning electron microscopic (SEM) images showed that the adhesive failure was dominant in both enamel and dentin groups and in all adhesive systems.
Conclusion: G-Premio Bond and Single Bond provided higher microtensile bond strength compared with Clearfil S3 Bond. Universal adhesives with their acceptable performance can be applied in self-etch mode on both enamel and dentin.

Published: February 2022

Background: A good quality of seating comfort requires integration of capabilities and limitations of the human body and the occupant’s preferred posture in different seating environments and tasks. This study provides a systematic and comprehensive review of past research related to the correlation between anthropometric parameter to seat pressure variables to determine the impact on comfort and safety in seat design.
Methods: This systematic review consisted of PRISMA flow diagram guidelines searched in Web of Science, Scopus, Sciencedirect and Google Scholar from 2009 till January 2020 related to keyword lists.
Results: As a result, 26 articles which addressed the correlation between anthropometric parameters and pressure variables were selected. Body mass index and weight were the most influence anthropometric parameter towards the pressure variables. In addition, almost all studies showed that there were medium to strong correlation between the lower body parts and the pressure variables, with R as above 0.5.
Conclusion: Comfort and safety depend on the design and ergonomics of the seat to maintain the body posture under complex roads, driving conditions and changing environment. In essence, seat and geometry functions help to reduce fatigue level and improve comfort, safety and health among drivers based on user, task and environment of driving activities.

Published: February 2022

Background: Vitamin D plays an essential role in the regulation of bone metabolism. The current meta-analysis aimed to assess the effectiveness of vitamin D fortification on special bone biomarkers.
Methods: Five main databases (PubMed/Medline, ISI Web of Knowledge, Science Direct, Scopus, Cochrane Library as well as Science Direct, and Scopus) were considered for this systematic review, until Jan 2020. All randomized controlled trials were included to evaluate the probable relationship between consumption of vitamin D fortification products and bone biomarkers profile in this review.
Results: Among serum bone biomarkers (osteocalcin and telopeptides of type-1 collagen) investigated, only the level of telopeptides of type-1 collagen significantly decreased after fortification of vitamin D in the intervention group. A significant increase in vitamin D was seen in those older than 18 yr old, while the increase in younger children was not statistically significant between intervention and control groups.
Conclusion: Vitamin D fortification was not associated with a significant improvement in bone mass density (BMD), while it resulted in decreased PTH levels. Vitamin D fortified foods have some benefits on bone health due to increase in the level of vitamin D and IGF-1; and decreasing PTH and CTx levels.

Published: February 2022

Background: The contamination of food products by Listeria monocytogenes as a pathogen bacterium, threatening public health and raised a global concern for a long time. Dairy and meat products and ready-to-eat foods are recognized as the most common carriers for L. monocytogenes.
Methods: The related reports of the prevalence of L. monocytogenes in dairy products in Middle East countries from 2009 to 2020 were screened through some of the international databases such as Science Direct, Web of Science, Scopus, PubMed, and Google Scholar. While a random effect model was applied to estimate pooled or overall prevalence, 95% confidence intervals (95%CI) were used.
Results: Results showed severe heterogeneity (84.2%) in studies and estimated the overall prevalence of L. monocytogenes dairy food products from the Middle East region of 3.5% (CI: 2.2-5). The highest and lowest prevalence was associated with Jordan (17.6% CI: 9.8-26.9) and Iraq (1.6% CI: 0.3-3.7), respectively. Based on the type of product, the highest and lowest prevalence of L. monocytogenes was recognized for raw cow milk (5.8% CI: 2.7-9.7) and pasteurized cow milk (1.1% CI: 0-8), respectively.
Conclusion: There is no justification for severe heterogeneity (I2) of subgroups as prevalence is heterogenic innately, but Jordan and row cow milk subgroups were found to have a considerable effect on overall pooled prevalence. Thus, they were the reason for prevalence changes.

Background: We examined the Korean adults’ experience with dental implants and analyzed its association with various socioeconomic factors.
Methods: This study was based on the participants enrolled in the 2013-2015 KNHANES. Using the variables associated with dental implant treatment experience and other socioeconomic factors, we evaluated the statistical significance and potential associations between the dental implant treatment experience and its related factors. The final analysis in this study was performed on adults aged 20 yr and over. It comprised 4,893 subjects in the year 2013, 4,431 subjects in 2014, and 4,430 subjects in 2015.
Results: An increasing number of individuals had reported undergoing dental implant treatment. An older age was associated with a higher likelihood of undergoing dental implant treatment, particularly in adults aged ≥40 years. Additionally, the likelihood was higher in individuals with a greater income level, low-level of educational background, and married status. Factors that were observed to influence dental implant treatment experience included age, education level, income level, marital status.
Conclusion: Our analysis confirmed the growing accessibility to dental implants among Korean adults and an association between dental implant treatment experience and socioeconomic factors. We recommend a healthcare policy on dental implants that considers relevant socioeconomic factors, in order to provide dental implant treatment to individuals who are in absolute need of treatment.

Authors: Bae Sung-Man
Published: February 2022

Background: The purpose of this study was to verify the effects of smartphone usage mo- tives on life satisfaction in older adults, and to examine the mediating effect of digital literacy in the relationship between smartphone use motives and life satisfaction.

Methods: Data from 2004 participants of the 2018 Smartphone overdependence survey were analyzed by structural equation modeling.

Results: Smartphone use for communication had a positive impact on life satisfaction, and smartphone use for leisure negatively influenced life satisfaction. However, smartphone use for information seeking was not directly related to life satisfaction. Communication and in- formation-seeking use motives positively influenced digital literacy, but smartphone use for leisure did not affect. Digital literacy was also positively related to life satisfaction. Finally, communication use motives influenced life satisfaction partially mediating digital literacy, and smartphone use for information seeking influenced life satisfaction, fully mediating digital lit- eracy.

Conclusion: By explaining how smartphone use motives significantly affect senior citizens’ life satisfaction, this study established the further meaningfulness of digital literacy.
Effect of Perceived Social Support on Psychache: Mediating Effect of Psychological Resilience
Authors: Zhang Ling , Pang Jinxia , Zhu Fangli
Published: February 2022

Background: As education develops, it proposes increasing requirements on the quality of teachers. Thus, attention on the mental health problems of teachers has also been gaining increasing attention. However, specific studies on the relationship among teachers’ perceived social support, psychache, and psychological resilience remain lacking.
Methods: Overall, 430 teachers (including teachers from universities, middle schools, and primary schools) from Zhejiang, Shanghai, Anhui, Hubei, Shanxi, Guangxi and other provinces in China were investigated in 2021 by using perceived social support scale, psychache scale, and psychological resilience scale.
Results: Teachers’ perceived social support is below the average, whereas psychache and psychological resilience are above the average. A significant gender difference exists in teachers’ psychache, and female teachers showed significantly higher teachers’ psychache than male teachers (P<0.05). Teachers’ psychache showed significantly negative correlations with perceived social support (r=−0.465, P<0.01) and psychological resilience (r=−0.526, P<0.01), but teachers psychological resilience had a significantly positive correlation with perceived social support (r=0.439, P<0.01). Teachers’ perceived social support (β=−0.465, P<0.01) could make a negative significant prediction of teachers’ psychache, and teachers’ perceived social support (β=0.435, P<0.01) could make a positive significant prediction of teachers’ psychological resilience. Moreover, psychological resilience had partial mediating effect between perceived social support and psychache, which accounts for 37.6% of the total effect.
Conclusion: Perceived social support not only is an important factor that influences teachers’ psychache directly but can also influence the psychache of teachers indirectly through psychological resilience.

Published: February 2022

Background: We investigated the impact of cancer incidence on CHE in Iran by considering spatial variation across provinces as well as temporal trends.
Methods: Data from Household Income-Expenditure Survey were merged with cancer incidence rates during 2011-2016. We developed a Bayesian hierarchical model to explore the spatial and temporal patterns of CHE and its associated factors at provincial level. We used a Besag-York-Mollie2 prior and a random walk prior for spatial and temporal random effects respectively. All statistical analysis was carried out in R software.
Results: All-type cancer incidence (OR per SD (95% CrI) = 1.16 (1.02, 1.32)), unemployment rate (1.08 (1.01, 1.15)) and income equity (0.88 (0.81, 0.97)) have important association with CHE. Percentage of urbanization and percentage of poverty were not statistically significant.
Conclusion: The results suggest the development of new policies to protect cancer patients against financial hardship, narrow the gap in income inequality and solve the problem of high unemployment rate to reduce the level of CHE at provincial level.

Authors: Salmani Hamzeh , Yahyaei Mahin , Raoofian Reza , Irani Shiva , Salahshouri Far Iman , Akrami Seyed Mohammad
Published: February 2022

Background: Mutations of the epidermal growth factor receptor (EGFR) gene, predominantly in exons 18-21, have been highlighted to function as the crucial predictors of the response rate of patients with non-small cell lung cancer (NSCLC) to EGFR tyrosine kinase inhibitors (TKIs).
Methods: This study was performed at Tehran University of Medical Sciences. Data and information were retrospectively collected from the period between Dec 2010 and Apr 2014. Exons 18 to 21 of the EGFR were analyzed for any potential mutation by PCR, accompanied by DNA sequencing on 160 with pathological confirmation of NSCLC.
Results: Demographically, the male to female ratio was approximately 2:1, and a substantial difference in age between sexes was not observed (P=0.065), but a noticeable difference was found in the smoking variable, where 77.8% of males were smokers compared to 17.3% of women (odds ratio (OR) (95% CI) = 16.72 (7.15-39.11)). We found a frequency of 10.63% (17/160) for mutations found in exons 19 and 21, nonetheless, no mutations in exon 18 and exon 20 were observed. The most frequently observed mutations were c.2235_2249, del and c.2240_2257, del in exon 19 and p. L858R in exon 21. The c.2253A>G was found as a novel mutation that was the rarest mutation detected in this work. Interestingly, a remarkable negative association was revealed between smoking and mutation rates in NSCLC patients (OR (95% CI) = 0.13 (0.04- 0.46).
Conclusion: The occurrence of EGFR mutations is largely varied among the different states of Iran, probably due to variations in ethnicity, smoking rate, and sex ratio of participants.

Modeling the Process of Blades Shaping with Intraoperative Correction of Cutting Parameters
Authors: Tanalin I.Sh.
Published: February 2022

The blades of gas turbine engines have a complex shape of the profiled part and low rigidity. In blade manufacture, there occur feather geometry errors, exceeding the tolerances of feather’s shape and dimensions. To minimize these errors, we propose a technological chain of mechanical processing of a blade on adaptively controlled machine tools, in which various cutting parameters and the trajectory of the cutting tool are adjusted to obtain the required geometry of the part. The use of intraoperative control allows calculating the correction value depending on the deviations of the actual parameters from the nominal ones. We built an ideal mathematical model, which will serve as the basis for the nominal shape of the blade, as well as a corrected geometric model of the blade for the subsequent operation. To calculate the correcting values ??of the parameters, we propose to use the mirror and secant methods. The mirror method consists in adding the error caused by the previous machining process to the current nominal depth of cut. The secant method is to express the nominal depth of cut of the next process as the sum of the nominal depth of cut of the previous process and the correction value. These methods make it possible to take into account the errors arising from previous operations.
Contour Machining Performance Improvement by Smoothing Spatial Piecewise Linear Toolpath and Quasi-Optimal Feed Rate Planning
Authors: Zelenskiy A.A. , Abdullin T.Kh. , Alepko A.V. , Ilyukhin Yu.V.
Published: February 2022

Currently, not all control systems of multi-axis machine tools and industrial robots are capable of efficiently machining the products with a complex surface shape. The toolpath for such products is usually described by blocks using G01 operator frames, which are short segments. To machine such a contour, it is necessary to periodically decrease the feed rate at the conjugation points of the segments, which leads to a decrease in performance and a lower quality of machining. The study introduces a method to solve the problem: smoothing the toolpath by including spline segments in it. When smoothing, we used a cubic B-spline with five control points, which made it possible for the entire path to have geometric continuity G2. The smoothing scheme enabled us to analytically express the maximum curvature, take into account the specified error in the approximation of the spline construction and the mutual intersection of adjacent curves. Contour machining performance was improved by using a bidirectional frame preview algorithm, which accounted for the specified geometric constraints and chordal spline construction error, as well as limits of the contour rate, acceleration and jerk in each segment of the path. The second-order Runge-Kutta method with a compensation approximation scheme was used for parametric interpolation, which made it possible to reduce fluctuations in the feed rate and positively affected the quality of the machined product surface. The experimental results confirm the correctness of the chosen approach and its validity in the control system for high-speed machining of products with complex surfaces.
Spacecraft Motion in an Ultra-Low Lunar Orbit under Lunar Gravitational Anomalies
Authors: Arinchev S.V.
Published: February 2022

The study centers around the interdisciplinary problem: gravimetry and celestial mechanics. A spacecraft is aimed at a flight from one point of the Moon to another at an altitude of 1 km in a flat circular orbit. Under gravitational anomalies, the orbit deviates from a circular one, acquiring a spatial character. To account for gravitational anomalies, we introduce the mass concentration method, according to which the resulting gravitational field is a superposition of elementary fields of individual mass concentrations (mascons). The elementary field of an individual mascon has four parameters: latitude, longitude, depth, and positive or negative mass. Each parameter of the mascon is associated with a pseudo-random variable with a uniform distribution law in a given interval. The pseudo-random values ??are generated by the Wichmann-Hill PRNG. The problem under consideration is reduced to the Cauchy problem with initial conditions. Under gravitational anomalies, a few orbits after the launch, the spacecraft falls onto the lunar surface. The study shows that one orbit is enough for a safe flight. The spacecraft moves in the specified ultra-low orbit under gravity-anomaly noise. Anomalous gravitational overload is 0.1 m/sec2.
Approximate Methodology for Design Ballistic Calculation of Two-Stage Launch Vehicles
Authors: Mukhamedov L.P. , Kirievskii D.A.
Published: February 2022

At the initial stage of building new models of rocket and space systems, so-called design ballistic calculations are usually performed. Due to the problems of deep space exploration and the creation of low-orbit satellite constellations with small spacecraft, the relevance of the tasks of design ballistics of launch vehicles has noticeably increased. The most cost-effective way to deliver small satellites to target orbits is to launch them using two-stage ultra-light launch vehicles powered by liquid propellants. To solve the problems of design ballistics of a two-stage launch vehicle, we expanded the technique of design ballistic calculation of the first stages of launch vehicles and tackled the problems of analytical determination of the characteristic velocity losses of the last stages of multistage launch vehicles. As a result, we introduce an approximate method for ballistic design calculation on the active part of the trajectory of two-stage launch vehicles when the payload is injected into a low Earth orbit with an arbitrary inclination. The paper considers the application of the developed technique on a specific example of injecting a payload into a circular polar orbit.

Application of the Flipped Classroom Approach in an Undergraduate Maternal–Newborn Nursing Course to Improve Clinical Reasoning
Authors: Hughes Kimberly N. , Berndt Andrea , Gill Sara
Published: February 2022

Application of knowledge is shown to improve student comprehension, but with dwindling hands-on clinical opportunities in nursing programs, active learning strategies need to be incorporated into classroom learning. Nursing faculty in an undergraduate nursing program transitioned from a lecture format to a flipped classroom format, thereby incorporating active learning. Quantitative and qualitative data on student performance were collected over three semesters. The Assessment Technologies Institute (ATI) maternal–newborn content mastery exam, used as the final examination for the course, was used to assess student academic performance. End-of-course student feedback was collected from the Campuslabs IDEA Student Rating of Instruction (SRI) evaluation to assess students ‘perceptions of their ability to understand and apply knowledge, as well as perceptions of the flipped classroom format in general. The ATI exam scores for the course did not change significantly, but the SRI showed a statistically significant increase in the percentage of students who felt they gained a “deeper understanding” and could “apply the knowledge and skills.” Although students resisted the flipped classroom format change initially, subsequent cohorts came to accept the change. Implications for educators are that although student dissatisfaction increased initially, the inclusion of the flipped classroom format within a course improved students ‘confidence in their ability to perform.
Beyond the DES-II
Authors: Leeds Andrew M. , Madere Jennifer A. , Coy D. Michael
Published: February 2022

The Dissociative Experiences Scale (DES-II) remains the most widely used brief screening tool for identifying dissociative symptoms despite limitations of the instrument and the training of those who use it. Standard eye movement desensitization and reprocessing (EMDR) therapy procedures require a thorough clinical assessment and formally screening for the presence of a dissociative disorder. This aids development of an accurate case conceptualization prior to the preparation and trauma reprocessing phases of EMDR therapy. Reliance on DES-II mean scores as the sole measure of dissociative features—particularly with persons reporting a history of early childhood neglect or abuse—is insufficient to determine readiness for safely reprocessing traumatic memories. The International Society for the Study of Trauma and Dissociation (ISSTD) Guidelines for Treating Dissociative Identity Disorder in Adults, Third Revision, noted that employing standard EMDR therapy with individuals suffering from an unrecognized dissociative disorder was reported as a risk for significant harm. EMDR-trained clinicians’ standard practice of screening for dissociative disorders must evolve beyond a casual reliance upon the DES-II. Consistent use of a mental status examination and reliable diagnostic tools is needed. Several relevant assessment tools are reviewed with their strengths and limitations. The authors recommend that clinicians apply these approaches even when their intent is to screen out persons whose presenting difficulties lie outside their scope of practice or research design.

Due to considerable progress in DNA nanotechnology, DNA is gaining significant attention as a programmable building block for the next generation of soft biomaterials. DNA has been used as either the only component to form all-DNA hydrogels or a cross-linker or functional entity to form hybrid DNA hydrogels through physical interactions or chemical reactions. The formed hydrogels exhibit adequate biocompatibility, convenient programmability, tunable multifunctionality, and capability of precise molecular recognition, making them an irreplaceable polymeric platform for interfacing biology. Responsive DNA hydrogels that are prepared through hybridization of DNA sticky ends, formation of i-motifs, enzymatic ligation, and enzymatic polymerization are commonly reported nowadays, which can undergo disassembly induced by various triggers, including alteration in ionic strength, pH, temperature, and biomolecules. These hydrogels are envisioned for applications of drug delivery and biosensing. This perspective aims to assess the most recent and important developments in this emerging class of biomedically useful DNA hydrogels.

 In lowland rice cultivation, farmers use chemical fertilizers without paying attention to the impact. If chemical fertilizers are not balanced with biological fertilizers, the organic content at paddy fields will decrease. This study aims to analyze the level of adoption, the factors that influence the adoption, and the strategies to increase the adoption of using biological fertilizers. This research was held in the Villages of Sukajaya, Sukamulya, and Sukarindik, Bungursari district, Tasikmalaya City, from April to June 2021. The research samples consisted of 71 farmers who were members of farmer groups. The samples were determined by using slovin’s formula. The variables of this study consist of internal factors, external factors, characteristics of innovation, and the level of adoption. Primary data was collected in the questionnaire form. The data was processed using descriptive analysis, multiple linear regression analysis, and SWOT analysis. The results of the study regarding the level of adoption of the use of biological fertilizers were in the medium category with a percentage of 49.3%. Factors that influence the level of adoption of biological fertilizers were formal education with a value of 0.026 <0.05, the relative advantage with a value of 0.001 <0.05, and the complexity with a value of 0.001 <0.05. The strategy to increase adoption using the SO strategy by maximizing to take advantage of farmer groups’ opportunities.

Tantangan Literasi Informasi Bagi Generasi Muda Pada Era Post-Truth
Authors: Fatmawati Endang
Published: February 2022

Generasi muda adalah generasi harapan bangsa. Literasi informasi berperan besar bagi perkembangan dan kemajuan bangsa. Literasi secara sederhana diartikan kemampuan membaca dan menulis. Artikel ini memfokuskan bahasan pada generasi muda sebagai pejuang literasi yang kreatif pada era post-truth. Secara umum dapat dipahami bahwa post truth menjadi tradisi kebohongan, berlebihan, dan ada unsur kepentingan politik. Indikasi fenomena post-truth salah satunya adalah beralihnya fungsi media sosial seolah-olah sebagai penyampai kebenaran, padahal pada kenyataannya, oknum yang dengan sengaja menyalahgunakannya untuk menyebar berita bohong. Pada tataran ini, generasi muda dituntut kreatif dalam memanfaatkan media dengan cara memilih dan memilah informasi secara tepat. Meskipun pemerintah telah menindak tegas pelaku penyebar hoaks (hoax), berita bohong (fake news), dan ujaran kebencian (hate speech), proliferasi dan viralisasi masih saja bermunculan dan menimbulkan keresahan di masyarakat. Dari berbagai fakta tersebut, multikompetensi dan multimodalitas dibutuhkan agar generasi muda bisa lebih kritis dan mampu memberikan solusi. Literasi informasi menjadi modal generasi muda dalam meningkatkan kreativitas untuk kemajuan bangsa. Hal ini karena dengan literasi informasi, generasi muda akan memiliki pengetahuan, keterampilan, maupun kecakapan hidup pada era post-truth.

Although great progress has been made in nanozymes, their large-scale application still remains a huge challenge due to their unsatisfactory catalytic performances. Featuring unique electronic structure and coordination environment, single atoms nanozymes provide great opportunities to vividly mimic the specific metal catalytic center of natural enzymes and achieve the superior enzyme-like activity. Herein, spin-state engineering of single-atom nanozymes was employed for the first time to enhance peroxidase (POD)-like activity. Pd nanoclusters (PdNC) were introduced to rearrange spin electron occupation of Fe single atom (FeNC-PdNC), in which the electron-withdrawing properties of PdNC make the spin transiting of Fe single atoms from low spin to medium spin, facilitating the heterolysis process of H2O2 and the desorption of H2O. As a result, the spin-rearranged FeNC-PdNC displays superior H2O2 activating performance and kinetics to FeNC. Finally, FeNC-PdNC was applied to the immunosorbent assay for the colorimetric detection of prostate-specific antigen, achieving an ultralow detection limit of 0.38 pg/mL. Our findings provide a new paradigm for designing advanced enzyme mimics and allow to gain a deep insight into the catalytic mechanism of nanozymes.
