Research on node importance evaluation of complex products based on three-parameter interval grey number grey relational model
Authors: Congdong Li , Weiming Yang , Yinyun Yu , Bingjun Li
Published: July 2021

In the process of product development, the identification and evaluation of important nodes is of great significance for the effective control of complex product engineering change. In order to identify and evaluate important nodes accurately, this paper proposes a method to evaluate the importance of complex product nodes. Firstly, an engineering change expression method based on multi-stage complex network is proposed. Then, the evaluation index system of important nodes of complex products is constructed. A three parameter grey relational model based on subjective and objective weights is proposed to identify and evaluate the important nodes of complex products. Finally, an example of a large permanent magnet synchronous centrifugal compressor is analyzed. The example shows that the top nodes are node 4, 1, 7, 9 and 24. Compared with other experiments, the proposed method can effectively and reasonably evaluate the node importance of complex products.

Published: July 2021

Machine Reading Comprehension has attracted significant interest in research on natural language understanding, and large-scale datasets and neural network-based methods have been developed for this task. However, most developments of resources and methods in machine reading comprehension have been investigated using two resource-rich languages, English and Chinese. This article proposes a system called ViReader for open-domain machine reading comprehension in Vietnamese by using Wikipedia as the textual knowledge source, where the answer to any particular question is a textual span derived directly from texts on Vietnamese Wikipedia. Our system combines a sentence retriever component, based on techniques of information retrieval to extract the relevant sentences, with a transfer learning-based answer extractor trained to predict answers based on Wikipedia texts. Experiments on multiple datasets for machine reading comprehension in Vietnamese and other languages demonstrate that (1) our ViReader system is highly competitive with prevalent machine learning-based systems, and (2) multi-task learning by using a combination consisting of the sentence retriever and answer extractor is an end-to-end reading comprehension system. The sentence retriever component of our proposed system retrieves the sentences that are most likely to provide the answer response to the given question. The transfer learning-based answer extractor then reads the document from which the sentences have been retrieved, predicts the answer, and returns it to the user. The ViReader system achieves new state-of-the-art performances, with values of 70.83% EM (exact match) and 89.54% F1, outperforming the BERT-based system by 11.55% and 9.54% , respectively. It also obtains state-of-the-art performance on UIT-ViNewsQA (another Vietnamese dataset consisting of online health-domain news) and BiPaR (a bilingual dataset on English and Chinese novel texts). Compared with the BERT-based system, our system achieves significant improvements (in terms of F1) with 7.65% for English and 6.13% for Chinese on the BiPaR dataset. Furthermore, we build a ViReader application programming interface that programmers can employ in Artificial Intelligence applications.
Food waste treatment option selection through spherical fuzzy AHP
Authors: Buyuk Aysu Melis , Temur Gul T.
Published: July 2021

In line with the increase in consciousness on sustainability in today’s global world, great emphasis has been attached to food waste management. Food waste is a complex issue to manage due to uncertainties on quality, quantity, location, and time of wastes, and it involves different decisions at many stages from seed to post-consumption. These ambiguities re-quire that some decisions should be handled in a linguistic and ambiguous environment. That forces researchers to benefit from fuzzy sets mostly utilized to deal with subjectivity that causes uncertainty. In this study, as a novel approach, the spherical fuzzy analytic hierarchy process (SFAHP) was used to select the best food treatment option. In the model, four main criteria (infrastructural, governmental, economic, and environmental) and their thirteen sub-criteria are considered. A real case is conducted to show how the proposed model can be used to assess four food waste treatment options (composting, anaerobic digestion, landfilling, and incineration). Also, a sensitivity analysis is generated to check whether the evaluations on the main criteria can change the results or not. The proposed model aims to create a subsidiary tool for decision makers in relevant companies and institutions.
On the Sub-D’s mean square error on “one-way” random designs
Authors: Silva Adilson , Fonseca Miguel
Published: July 2021

Through simulations, it was shown that either in balanced “one-way” random designs or in unbalanced “one-way” random designs, Sub-D estimates are in general more accurate than those provided by Anova-based estimators. Moreover, the Sub-D estimates exhibit less dispersion magnitude. Such estimates reveal to be also slightly more accurate than those provide by REML-based estimator, although this latter one presented dispersion with slightly less magnitude, which, indeed, is not bigger than 0.0261. In order to have somehow a robust tool which will allow us to infer over Sub-D’s efficiency in “one-way” random designs, this paper aims to deduce and discuss its MSE.

Authors: Calhoun Thielen Christina , Slavin Mary D. , Ni Pengsheng , Mulcahey MJ
Published: July 2021

PURPOSE: To develop ability levels and descriptions to interpret Pediatric Spinal Cord Injury Activity Measure (PEDI-SCI AM) and Pediatric Measure of Participation (PMoP) scores. METHODS: Mixed-methods approach to 1.) create item maps using PEDI-SCI AM and PMoP calibration data; 2.) employ bookmarking methods and an iterative consensus process including semi-structured interviews, focus groups and surveys to establish PEDI-SCI AM and PMoP level score cut-points and descriptions; 3.) use calibration sample data to examine mean score differences across levels [analyses of variance (ANOVAs)] and assess the sample distribution (%) across levels; 4.) repeat in a separate validation sample; 5.) develop level descriptions. Throughout the mixed methods approach, the sample participants include children with spinal cord injury (SCI), parents of children with SCI, and professionals who work with children with SCI. RESULTS: Four or five ability levels were identified for each PEDI-SCI AM and PMoP domain along with descriptions for each level. ANOVA results revealed significant overall differences for level mean scores and pairwise comparisons (p < 0.05). Consensus (>80%) was achieved for all PEDI-SCI AM and some PMoP level descriptions. CONCLUSION: PEDI-SCI AM and PMoP score cut-points identify different levels of activity and participation among children with SCI. These levels and descriptions provide clinical relevance for PEDI-SCI and PMoP numeric scores.

Authors: Yoo Hye Jin , Kim Jeongeun , Kim Sukwha , Jang Seon Mi , Lee Hyeongsuk
Published: July 2021

BACKGROUND: Many inpatients become anxious or frightened about scheduled treatment processes, and medical staff do not have sufficient time to provide emotional support. The recent advancement of information and communications technology (ICT) and the use of artificial intelligence (AI), including robots, in the health care field is being put to the test. OBJECTIVE: This study aimed to develop a bedside robot system to deliver information and provide emotional support to inpatients and to evaluate the usability and perceptions of the developed robot. METHODS: The first stage was accomplished by deriving essential functions from the results of user demand surveys on robots and by implementing a prototype by mapping each essential function to the robot’s hardware and software. For the second stage, the robot was assessed for usability and perceptions in a simulation center, a hospital-like environment, by 10 nurses, 10 inpatients, and family caregivers. Usability and perception were evaluated using the think-aloud method, a survey, and individual interviews. RESULTS: Based on the usability evaluation, the perceived usefulness, ease of use, and satisfaction were 5.28 ± 1.27 points, 5.42 ± 1.55 points, and 5.27 ± 1.46 points out of 7, respectively. It was found that overall, the robot was positively perceived by participants. As a result of the qualitative data analysis, the participants perceived the robot as an object that had the positive effect of providing emotional support through communication. CONCLUSIONS: The bedside robot in this study, which incorporated human-robot interaction (HRI) technology, is an alternative suited to the new normal era that will contribute to ensuring that patients have more self-directed hospital stays as well as emotional support through information delivery and communication.
Efficacy and safety of long-term sirolimus use as part of multidisciplinary care in a pediatric patient with CLOVES syndrome: Case report
Authors: Leonard Alexis , Diab Yaser , Tosi Laura L.
Published: July 2021

BACKGROUND: CLOVES (congenital lipomatous overgrowth, vascular malformations, epidermal nevi, scoliosis/skeletal/spinal) syndrome is a rare and progressive genetic disorder resulting from somatic mosaicism in activating mutations in the phosphatidylinositol-4,5- bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) gene. PIK3CA is a cell growth master regulator where gain of function mutations give rise to abnormal activation of the PI3K-AKT- mammalian target of rapamycin (mTOR) pathway. Treatment with sirolimus, an mTOR inhibitor, may therefore be of benefit in patients with CLOVES syndrome. OBJECTIVE: Here we describe the efficacy and toxicity of sirolimus in a pediatric patient with progressive CLOVES syndrome. RESULTS: The child presented with a large and painful abdominal malformation, massive overgrowth of his feet, limb length discrepancy and genu valgum. There was dramatic clinical and radiographic improvement in the size and comfort of his abdominal mass within several months of initiating medical therapy. This, combined with orthopaedic care of his genu valgum, leg length discrepancy, and overgrowth of his feet, has allowed for significant functional gains. CONCLUSIONS: Multidisciplinary care is essential for comfort and functional gains in patients with CLOVES syndrome, particularly those with severe symptoms. Close monitoring while on sirolimus medical therapy combined with frequent reassessment of orthopedic needs can dramatically improve patient quality of life and outcomes.
Financial Sector Development, Trade Openness and Economic Growth Nexus: Evidence from SAARC Countries
Authors:   International Islamic University, Islamabad, Pakistan, Haq Mirajul
Published: July 2021

To boost economic growth, SAARC countries resorted to trade liberalization policies since mid-1980s, therefore, now it is high time to evaluate the outcomes of this outward-oriented trade regime. Available literature confined the potential gain with the trading country’s status of the financial sector development. This study therefore empirically investigates the complementarity between domestic financial sector and trade openness for its growth effectiveness in the case of SAARC region. The empirical analysis basis upon the panel of six SAARC countries, using panel co-integration technique for the period 1980-2014. The empirical estimates of FMOLS and DOLS indicate that countries holding relatively developed domestic financial sectors enjoy larger gains from trade openness, which finally translates into economic progress. To be exact, the country’s domestic financial sector plays a complementary role between openness and growth in SAARC countries. Results hence suggest that SAARC countries need to lay higher emphasis on the development of the domestic financial sector.

Correct measurement methodology spatial-energy characteristics of laser beams
Authors: Raitsin A. M. , Ulanovskii M. V.
Published: July 2021

A methodology for correct measurements of the spatial and energy characteristics of a laser beam is considered, based on the determination of the initial moments of the spatial intensity distribution in the beam cross section. The classification of radiation fields participating in the measuring process is given: emitted, measured and measured. It is shown that ISO 11146:2005 “Lasers and laser-related equipment. Test methods for laser beam widths, divergence angles and beam propagation ratios, Part 1-3” for measuring the spatial and energy characteristics of laser beams leads to incorrect measurements. This is due to the fact that the recommendations for the application of ISO 11146:2005 do not take into account the dynamic range of the used matrix radiation detectors, and the characteristics of the emitted field of interest to the user turn out to be diverging, which violates the uniformity of measurements. Moreover, the conditions ensuring the convergence of the results are practically impracticable. To solve these problems, it is proposed to establish and regulate the lower level of the dynamic range of measurements of the intensity of the used matrix receivers and to consider the spatial and energy characteristics of the emitted field of interest to the user, depending on the set value of the lower level. It is shown that measurements with this methodology become correct and make it possible to compare the characteristics of laser beams obtained by different array detectors. Formulas are given that take into account the effect of the lower level of the dynamic range of the matrix radiation detectors on the measurement result. These formulas should be recommended for inclusion in the updated edition of the national standard GOST R ISO 11146-2008 “Lasers and laser installations (systems). Methods for measuring widths, divergence angles and propagation coefficients of laser beams. Parts 1-3”.

Authors: Vy Nguyen Tuong , Pham Nguyen Thi Khoi , Ha Lam Quoc
Published: July 2021

Polyvinyl alcohol (PVA) is well-known in the packaging industry, especially in the food and medical fields with the ability to be completely biodegradable and easily soluble in cold water therefore products made from it are the environmentally friendly materials. However, the disadvantages of this polymer as quick dissolubility in water, poor moisture retention, weak mechanical properties reduce its applications. In this study, PVA, reinforced by “green” components at the nanometer-level such as nanocellulose fibers (CNF), graphene oxide (GO) nanosheets showed improvements in properties. Mechanical properties of all of nanocomposite films showed improvements in stress at break and modulus. Especially, reinforced GO and CNF films increased almost doubled and improved more 40% in modulus than the pure PVA film and films reinforced by only GO or CNF. When immersed in water (neutral pH) at room temperature, graphene oxide-reinforced films not only had effective improvements in swelling time but also supported to decrease water retension of film added CNF. The combined reinforcement also indicated a benefit in reducing the rate of water vapor loss of the film as well as the efficiency in declining the moisture absorption of the nanocomposite films. The PVA films reinforced by nanocellulose fibers and graphene oxide sheets overcomed some of the PVA's shortcomings. This helped expanding its applications in the field of environmentally friendly nanocomposite films.

Authors: Rois Habib
Published: July 2021

Changes in the meaning of words with refinement (euphemism) and refinement (dysfemism) occur at the level of a sentence marked by words, phrases and clauses. The purpose of this research is to describe the forms of euphemisms and dysphemisms in the essay of Emha Ainun Nadjib (Cak Nun) with the title "Life Must Be Clever Ngegas and Ngerem" through a component analysis. The paradigm in research uses qualitative by referring to the natural axioms of reality, the relationship between the researcher and the one being studied, the possibility of generalization, and the causal relationship. The data in this study are in the form of sentences in Cak Nun's essay which are included in the process of changing the meaning of euphemisms and dysfemisms. The data is taken from a book entitled "Life Must Be Smart and Ngerem", an article that contains motivation and teachings of life based on Islamic law. The data analysis process in this study includes four stages, namely domain analysis, taxonomic analysis, component analysis, and cultural theme analysis. The results in this study contain a form of euphemism with two modes of use, namely protection and motivation. Meanwhile, dysphemism has two modes of use which include negative evaluation and satire. The four modes are then combined with the equivalent words in accordance with the context of the sentence, giving rise to comparisons based on the meaning components contained. Comparison of meaning components aims to determine the level of meaning change which refers to refinement and roughing. There is one word without comparing the meaning component with its equivalent, namely the word pramonyet. The term pramonyet is used as a form of curbing which refers to the process of comparing human needs with a monkey.

Objectives: This study aimed to compare the effectiveness of reality therapy and positive psychotherapy on sleep quality in women with MS. Materials & Methods: The research method was quasi-experimental with a pre-test, post-test design and a control group. The study population included all women with MS referred to the Guilan MS Association in the summer and fall of 2019 who were selected by purposive sampling method. They were randomly assigned in three groups of 15 people for reality therapy training, positive psychotherapy, and control group. Both experimental groups received eight 90-minute sessions of psychotherapy interventions, but the control group received no training. The Pittsburgh Sleep Quality Index (PSQI) was used to collect data. Data analysis was performed by Multivariate Analysis of Covariance (MANCOVA) and Bonferroni post hoc test in SPSS version 22. Results: Both reality therapy and positive psychotherapy significantly improved sleep quality in women with MS (P<0.01). Also, based on the results, the sleep quality of the reality therapy group showed a greater and more significant improvement compared to the positive treatment (F=19.43, P<0.01). Conclusion: According to the obtained results, both methods have good practical capabilities for clinical interventions to improve sleep quality in patients with MS. Reality therapy is more effective than positive psychotherapy on the quality of sleep in women with MS.

Background: Autism Spectrum Disorder (ASD) occurs based on the continuous deficit in a person’s verbal skills, visual, auditory, touch, and social behavior. Over the last two decades, one of the most important approaches in studying brain functions in autistic persons is using functional Magnetic Resonance Imaging (fMRI). Objectives: It is common to use all brain regions in functional extraction connectivity, which leads to high dimensional space. In this study, a Genetic Algorithm (GA) has been used to select effective regions for the generation of Functional Connectivity Matrix (FCM) to differentiate between healthy and autistic people. The aim is to increase accuracy, reduce processing time, and lower the dimension of the functional connectivity matrix. Materials & Methods: In this analytical study, the dataset includes 820 fMRI images consisting of 445 healthy samples and 375 people with ASD obtained from the autism brain imaging data exchange database. The K-nearest neighbor classification algorithm and the genetic algorithm were used to optimize the identification of two groups of autism and healthy people. Results: Regarding the large dimensions of the search space, the use of genetic algorithms after 100 replications estimated the accuracy for test and validation data at 61.08% and 62.59%, respectively. The obtained results show that the genetic algorithm can increase the classification accuracy by 10% on test data and 7% on validation data by selecting 67 regions. Conclusion: The obtained results prove that the proposed method is a well-designed system and can differentiate between autistic and healthy people effectively.

La geografía cultural de Luis A. Martínez: espacios e identidad
Authors: Sinardet Emmanuelle
Published: July 2021

Con la novela A la Costa (1904) de Luis A. Martínez, el espacio de la Costa entra en la narrativa del Ecuador. La relación entre geografía y literatura da fe, aquí, de una original apropiación cultural de la naturaleza costeña, la cual es transformada por las numerosas y detalladas descripciones del narrador en espacios-valores. La autora estudia las modalidades del trato de los espacios y de los paisajes, entre realismo, costumbrismo y romanticismo herderiano, para entender los valores que asumen los espacios costeños; valores que no solo son económicos, políticos o ideológicos, sino también identitarios y hasta espirituales. Se observa cómo van moldeando un genio que remite a un Volkgeist singular en el panorama cultural de la época, por tener una dimensión sublime, la misma que caracteriza, por cierto, la producción pictórica del Martínez paisajista.

Published: July 2021

The background of the problem of this research is that the teacher in conducting learning has not fully implemented an appropriate learning model and is in accordance with the way students learn. This raises a problem when teachers apply a monotonous learning model and there is no compatibility with the learning styles of their students, the learning process does not attract students' learning interest so students have difficulty understanding the material being taught. The problem in this study is: how is the effectiveness of the MURDER learning strategy (Mood, Understand, Recall, Digest, Expand, Review) to improve the understanding ability of high school students, whether the MURDER learning strategy (Mood, Understand, Recall, Digest, Expand, Review) can improve the comprehension ability of high school students. This research is a Classroom Action Research (CAR). In the learning process researchers use Fiqh subjects as research material. The subjects of the study were students of Class X IPA 1 High School BPPT Darul Ulum Jombang. Data collection is done by observation, interviews, and tests to complete the data revealed. Meanwhile, to obtain the validity of the data, the authors use technical triangulation analysis. Source triangulation is used to test the credibility of the data carried out by checking the data obtained through several sources.

Published: July 2021

The purpose of this study was to analyze the Economic Evaluation in the Production of Copper Nanoparticles (Cu-Nps) using Rongalite as Reducing Agent, an experimental method carried out in the perspective of engineering and economic evaluation. Technical analysis was performed using simple mass balance analysis, while economic evaluation was carried out using several economic parameters, including PBP, BEP, and CNPV. To support the analysis, all data is taken based on the available online shopping web. All calculations are carried out in ideal conditions for 20 years of production. Economic evaluation is carried out by giving 5 conditions (0%, 20%, 40%, 60%, and 80%) to the variable price variations in cost, sales, fixed cost, and labor. Economic evaluation analysis results show that price variations can affect the CNPV / TIC (%) curve to Life Time (year). In the variable cost, fixed cost, and labor variable price curve it is found that the condition of 0% is the highest curve compared to other conditions. While in sales price variations, the 80% condition is the highest curve. In conclusion, all price variation curves show profit. The benefits of this research are the large-scale economic evaluation data on Cu nanoparticle production.
ТЕНДЕНЦІЇ РОЗВИТКУ ФАХОВОЇ ПЕРЕДВИЩОЇ ОСВІТИ В СУЧАСНИХ УМОВАХ
Authors: Курок Роман
Published: July 2021

Актуальність дослідження зумовлена необхідністю визначення місця фахової передвищої освіти у вітчизняній освітянській системі та перспектив розвитку цієї новоутвореної ланки професійної освіти.

Мета: окреслити основні напрямки розвитку фахової передвищої освіти в сучасних умовах реформування освітньої діяльності в Україні.

Методи: аналіз, синтез, аналогія, індукція, дедукція, абстрагування, логічний метод.

Результати: доведено, що на сьогодні стан підготовки здобувачів професійної освіти ще не повною мірою відповідає сучасним потребам ринку праці. Виокремлено основні чинники, які негативно впливають на стан підготовки відповідних фахівців: тривалий процес формування системи фахової передвищої освіти та структурні зміни в діяльності відповідних освітніх закладів; незавершеність законодавчого та відомчого нормативно-правового регулювання цього рівня освіти; недостатнє фінансування галузі; недосконалий механізм формування державного замовлення, який не повною мірою відображає потреби ринку праці; недостатня участь роботодавців у формуванні змісту освіти, розв’язанні проблем фахової передвищої освіти; недостатній кадровий потенціал та недосконалість системи підвищення кваліфікації та стажування педагогічних працівників тощо.

Висновки: в науковій статті окреслено основні напрямки розвитку фахової передвищої освіти: завершення процесу формування її нормативно-правової бази; стандартизація підготовки здобувачів за освітньо-професійним ступенем «молодшого бакалавра»; закріплення принципів студентоорієнтованого навчання в освітньому процесі; розширення мережі закладів із сучасною навчально-виробничою інфраструктурою та формування єдиної системи професійної освіти, яка б поєднувала професійно-технічну та фахову передвищу освіту; реалізація нової децентралізованої моделі управління та фінансування галузі; удосконалення якісного складу педагогічних працівників, які здійснюють підготовку здобувачів освіти.
