Authors: Yusuf Mohamad Fahmi , Pramana Edwin , Setiawan Esther Irawati
Published: March 2023

E-marketplace saat ini telah berkembang sangat pesat. Pemerataan wilayah coverage dan kecepatan koneksi sudah jauh semakin berkembang, maka perubahan aktivitas dari tradisional menjadi digital pun semakin tinggi. UMKM di Indonesia mulai bermigrasi dari yang sebelumnya menjual produk secara konvensional di toko dan pasar, sekarang beralih secara online lewat media sosial maupun e-marketplace. Repurchase intention sangat penting dan sangat diinginkan karena untuk mendapatkan kepercayaan pelanggan baru dibutuhkan biaya yang besar. Proses mendapatkan pelanggan baru dan mengubahnya menjadi transaksi pembelian, lima kali lebih mahal daripada mempertahankan pelanggan yang sudah ada. Tujuan penelitian ini adalah untuk mengidentifikasi faktor-faktor yang mempengaruhi niat repurchase intention dalam e-marketplace dan untuk mengetahui hubungan antar faktor-faktor tersebut. Tahap awal penelitian ini adalah pengembangan model teoritis dan kuesioner, kemudian prosedur sampling & analisis data, dan interpretasi hasil & kesimpulan. Langkah pemrosesan data dimulai dengan factor analysis, reliability test, dan mencari nilai cronbach alpha. Selanjutnya dilakukan penggambaran model teoritis dengan AMOS dan dilakukan analisis SEM dari model construct ECM yang diberikan sehingga output yang didapatkan adalah hasil nilai standardized effect dan nilai magnitude. Kesesuaian penelitian ini dengan model penelitian yang diajukan dalam tabel Fit Statistic Model. Hasil penelitian menunjukkan terdapat enam faktor diterima yang mempengaruhi repurchase intention yaitu trust, confirmation, satisfaction, brand awareness, ease of use, dan electronic word of mouth, dan tiga hipotesis yang ditolak yaitu security terhadap repurchase intention & trust dan brand awareness terhadap repurchase intention.
A study on the right knowledge(tattvajñāna) in the “Akṣapādadarśana”, the 11th chapter of Sarvadarśanasaṃgraha
Authors:   Korean Institute for uddhist Studies, Park Ki Yeal
Published: March 2023

Naiyāyikas say that the highest good is achieved through the right knowledge (tattvajñāna) for the sixteen topics (padārtha), beginning the means of knowledge, the object of knowledge, etc. The acquisition of the right knowledge would be the direct cause to remove the wrong knowledge (mithyājñāna), and the mental disturbances (doṣa), the bad activities (pravṛtti) by body-language-mind, birth (janman) one after another would be removed. Finally, the right knowledge leads to reaching liberation (apavarga), being in the complete extinction of suffering. This order to get liberation is backward against the order to generate suffering. Therefore, it could be said that the attainment of the right knowledge is the key to have liberation that is the highest good. The classic Nyāya theory, however, does not concretize the acquisition method of the right knowledge, but in Sarvadarśanasaṃgraha (SDS) Ⅺ, there is a supplement on how to get the right knowledge. That is the role of the Supreme Being (parameśvara) as the direct cause to raise the right knowledge. It is defined as the authority (or proof) of the right means of knowledge (prāmāṇya) that tends not to be emphasized in the classic Nyāya school. Mādhava says in SDS Ⅺ that it is required to attain preveniently dharma on the Supreme Being as the authority of the right means of knowledge through śabda, one of the means of the right knowledge-s (pramāṇa-s) defined as teachings by a trustful teacher (āptopadeśa) according to Nyāya’s theory. Practicing the contemplation (samāhi) repeatedly and continuously, keeping the dharma of the Supreme Being at the same time, Yogi could, at last, come to the right knowledge. It does not mean the Supreme Being is the object of knowledge, but the means of knowledge in the yoga practice. The concept of the dharma is supposed to be influenced by the dharma in VS 1.1.2. The sūtra defines dharma as the means to reach at exaltation (abhyudaya) and the highest goods (niḥśreyasa). The paper considers the above summary of Nyāya’s liberation theory with the right knowledge as the central figure through the examination of the quoted Nyāyabhāṣya and Udayana’s Nyāyakusumāñjali 4.5.-6. in SDS Ⅺ, splitting up the contents on the right knowledge into the definition of, the role of, and the attainment of the right knowledge chapter. The paper would have a chance to introduce Nyāya school’s liberation and the practice. There may have been overemphasized the aspect of the epistemological and logical theory of the Nyāya school as compared to the aspect of the liberation and truth of the Nyāya school. On the other hand, the paper would show the fragmentary aspect that Mādhava tries to consolidate the liberation theories of the traditional philosophy schools (āstika-s) into one theory in SDS Ⅺ based on the thought of Udayana, who had integrated both theories of Nyāya and Vaiśeṣika school.
Is It Kamalaśīla Who Criticizes Mahāyāna (摩訶衍)’s the Buddha-Nature Theory as the Ātman Theory of the Non-Buddhists in the Ratification of the True Principle of the Mahāyāna Teaching of Sudden Enlightenment (Dùnwù dàchéng zhènglǐ jué 頓悟大乘正理決)

Through the colophon of the Summary of the Essential Points of the Mahāyāna Sūtras (Dàshèng jīng zuǎn yàoyì 大乘經纂要義, Or.8210/S.3966 and PC2298) unearthed from Dunhuang, it can be seen that the gradual teaching of Indian Buddhism was approved officially in Tibet in 822. As described in Tibetan history writings such as the Ba’s Testimony and the Chronicle of Buddhism in India and Tibet, it can be confirmed that King Khri srong lde brtsan (reigned 755-797) did not approve officially the gradual teaching of Indian Buddhism after the Kamalaśīla (ca. 740-795) and Mahāyāna (摩訶衍, fl. late 8th c.)’s debate, but only in 822, when King Khri gtsug lde brtsan (reigned 815-841) was reign. In the True Principle of the Mahāyāna Teaching of Sudden Enlightenment (Dùnwù dàchéng zhènglǐ jué 頓悟大乘正理決), Indian Buddhist criticizes Mahāyāna’s concept of “Buddha-nature.” The gist of the criticism of Indian Buddhist is that the concept of ‘Buddha-nature’ is similar to the ‘self (ātman)’ theory of non-Buddhists. If Kamalaśīla and Mahāyāna had a direct debate with Tibetan historical writings such as the Ba’s Testimony and the Chronicle of Buddhism in India and Tibet as described by modern scholars such as Eugene Obermiller, Paul Demiéville, and Giuseppe Tucci, etc., would Kamalaśīla criticize Mahāyāna’s theory of Buddha-nature as the non-Buddhists’ theory like the description of the True Principle of the Mahāyāna Teaching of Sudden Enlightenment. Kamalaśīla, an eminent Indian scholar-monk belonging to the Yogācāra-madhyamaka, interprets Buddha-nature’s teachings as a teaching featuring “selflessness (nairātmya)” after setting the teachings of One-vehicle (ekayāna) as the entire theme in his work, the Madhyamakāloka. It can be seen that his understanding of Buddha-nature is closely connected to a phrase, “the embryo of the tathāgata, which is selflessness (tathāgatanairātmyagarbha)” in the Laṅkāvatārasūtra. Through this, it can be confirmed that Kamalaśīla is not the one who criticizes Mahāyāna’s theory of Buddha-nature as the ‘self (ātman)’ theory of non-Buddhists in the True Principle of the Mahāyāna Teaching of Sudden Enlightenment.
The perception of reality and the change of the thought of the Buddha Land(佛土觀) of the Buddhist community in the Late Silla
Authors:   Korean Institute for uddhist Studies, Sin Sun Hye
Published: March 2023

It is not easy to find aspects of the people's perception of realities in the ancient Korean society. The limit of historical records is thought to be the biggest factor, but fortunately, a glimpse of such aspects can be obtained since relatively many epigraph in Late Silla with which aspects of the Buddhist community can be examined, including the Zen monks’ epitaph, remain. In this paper, examples in which the Late Silla Buddhism perceived the contemporary era as the degenerate age(末法) have been examined, and although common expressions related to the degenerate age were seen, the fact that the situation perceived as the degenerate age was different depending on the subject of the Buddhist custom was able to be found. In particular, the fact that the royal family perceived the contemporary era as the degenerate age can be said as a perception deviating from the one-sided understanding that the degenerate age perception held an anti-royal feature. The background behind the spread of the degenerate age perception was due to not only the domestic situation of the proliferation of the Maitreya belief since the Jinpyo(眞表), but also the foreign situation, the return of the Zen monks by the persecution of Buddhism(破佛) of the Chinese Tang(唐) Mujong(武宗). Since the Tang’s situation of the weakening of the royal family and the rise of local power resembled the reality of Silla, Silla also perceived the degenerate age in light of the Tang which resulted in the extreme situation on the persecution of Buddhism. The Buddhist community responded actively without neglecting such reality. The thought of the Buddha Land(佛土觀), which in the previous periods had spread centering around the royal family and the royal capital, changed into a local-centered ideology, proliferated the perception of accomplishing Buddhahood(本來成佛), and attempted to overcome the crisis of chaotic reality of Late Silla. As such, the Buddhist community persistently made an effort to communicate with the society and lead the society.

“Hosseiniyeh”; An In-between Space in the Iranian Traditional Cities
Authors: SOLEİMANİ Meysam , GOLABİ Maryam
Published: March 2023

The present study aims to analyze the socio-spatial roles of Hosseiniyeh, a neighborhood square in traditional Iranian cities. The hypothesis of the research is that Hosseiniyeh acted as an in-between space within the hierarchical urban structure. The notion of in-betweenness reveals architectural qualities that support the reciprocal states of separation and connection between conflicting realms. In-between spaces are the key elements to preserve the integration of urban areas. When these intermediate spaces disappeared as a result of modernist planning, their importance was revealed. It is useful to reconsider in-between spaces in the real context. In the organic urban fabric of Iranian historic cities, “Hosseiniyeh” was configured as a transitional space between the public (Bazaar) and the semi-public realms (neighborhood). With its unique urban location, this neighborhood square can be an appropriate case of the in-between space. Developed during the Shiite Safavid government (1501 to 1736), the main function of Hosseiniyeh was to serve as a venue for Ta'ziyeh, the only indigenous theater engendered by the world of Islam. The present study aims to evaluate the architectural qualities of Hosseiniyeh based on the theoretical framework of the in-between space. The spatial characteristics of the square and its architectural components are compared with the various states of the in-between space. The findings illustrate that the historic square meets the qualities of an in-between space. Connecting the two socially and functionally different areas, Hosseiniyeh was an intermediate urban space that indicated the end of a public realm and the beginning of a residential district. With its specific socio-political character, the square protected the Shiite identity and reinforced the urban unity. The present study contributes to an understanding of how an in-between space acted in a real urban context.

We investigate the electrical characteristics of Ni Schottky contacts on n-type GaN films that have undergone ultra-high-pressure annealing (UHPA), a key processing step for activating implanted Mg. Contacts deposited on these films exhibit low rectification and high leakage current compared to contacts on as-grown films. By employing an optimized surface treatment to restore the GaN surface following UHPA, we obtain Schottky contacts with a high rectification ratio of ∼109, a near-unity ideality factor of 1.03, and a barrier height of ∼0.9 eV. These characteristics enable the development of GaN junction barrier Schottky diodes employing Mg implantation and UHPA.

Authors: Bello Y. , Msheliza D. S. , Abaje I. B.
Published: March 2023

This study examined the patterns of rainfall in Billiri. Rainfall data for 40 years from 1977 to 2016 were collected from the Gombe State Agricultural Development Program (GSADP) Ladongor station in Billiri. Descriptive statistics for both rainfall and rainy days and the Seasonality Index (SI) of the rainfall were determined. Linear time series analysis was used to determine the nature of the trend of both rainfall and rainy days. To identify variation within the trends, both the rainfall and rainy days series were divided into four-decade2, ten (10) years each from 1977-1986, 1987-1996, 1997-2006 and 2007-2016. Spearman’s rank correlation was used to determine the relationship between rainfalls total and the number of rainy days, the result of the statistics shows that the maximum and minimum rainfall were 1407.9mm, and 363mm respectively while the maximum and minimum rainy days were 60 and 27 days respectively. The SI of the station was markedly seasonal with a long drier season and there are more years of negative anomalies than positive anomalies. The linear trends show that both the rainfall and the number of rainy days decreased over time. There was a change in the patterns of rainfall and rainy days in each decade. A very weak relationship existed between rainfall totals and the number of rainy days. The study recommends that the agricultural extension workers should inform the farmers about the recent trends of rainfall in the study area.
Distributed Impedance Control of Coordinated Dissimilar Upper-limb Exoskeleton Robots
Authors: Tahamipour-Z. S. Mohammad , Mattila Jouni
Published: March 2023

Upper-limb exoskeleton (ULE) arms have the potential to assist humans to accomplish tasks by distributing a heavy load. ULE arms are designed to be comfortable and lightweight wearable robots which has resulted in complexity in their structures, actuators, and power transmissions. Additionally, different ULE vendor structures and biomechanical variations between humans resulted in dissimilar coordinated ULE arm systems. These complex multiple ULE arm systems can be handled by adaptive virtual decomposition control (VDC) if unknown dynamic models are not considered. Hence, this paper proposes a new distributed framework for the adaptive impedance-based VDC method to the address abovementioned challenges and thereby enhance the system performance and robustness. To that end, the proposed control method has a prediction capability and an ancillary control law for coordinated dissimilar ULE arms holding a common object. The system stability is analyzed using the input-to-state stability approach. The performance of the proposed controller is evaluated in both simulation with six coordinated ULE arms and in experimental with two commercial coordinated ULE arms each with seven degrees of freedom. Four scenarios are performed with different internal arm forces and with/without an obstacle. The simulation and experiment results are compared with a state-of-the-art adaptive VDC method and show the superiority of the proposed control method. 
Performance Analysis of UAVs System in THz-Band Communications under Different Fading Channels
Authors: Karabulut Muhammet Ali
Published: March 2023

 Unmanned aerial vehicles (UAVs) are safer than manned vehicle and raise the interest to researchers for their huge applications in 5G and upcoming 6G. In 6G, terahertz (THz)-band communications can be used for fast communication. In this paper, the THz wireless communication between UAVs is considered. The performance of UAVs communications in the THz networks is analyzed under different fading channels which are major influence factors in the THz communication channel modeling. It is crucial to assess the performance of wireless devices taking into account their structure, wireless channel parameters, and transmission characteristics. Log-normal Fading, Weibull Fading Channel, Nakagami-m Fading Channel, Rician Fading Channel and Rayleigh Fading Channel are taken into account. Performance influencing parameters are considered and analytical expressions concerning capacity, outage probability, and bit error rate (BER) are obtained. Numerical results are presented which verify the analytical analysis.  
A Linear Distflow Model Considering Line Shunts
Authors: Lin Hanyang , Shen Xinwei , Guo Ye , Ding Tao , Sun Hongbin
Published: March 2023

Line shunts are usually ignored by various power flow (PF) models in distribution system analysis, planning and optimization. However, ``charging effects" from line shunts of underground/submarine power cables would cause non-negligible model errors for these commonly used PF models. In this brief, we propose a modified linear Distflow model (LinDist) with line shunts (LinDistS) to address relevant model errors. The strength of the proposed model not only lies in a straightforward structure like LinDist, but also maintaining the linearity after further considering three-phase unbalanced systems. The linearization error of voltage component is theoretically analyzed. Case studies show that compared with non-linear and linear models, LinDistS achieves the descent calculation accuracy and efficiency in large scale distribution systems.
A Deep Neural Network Approach for Detection and Classification of GNSS Interference and Jammer
Authors: Ebrahimi Mehr Iman , Dovis Fabio
Published: March 2023

Global Navigation Satellite Systems (GNSS) are one of the most important infrastructures in the modern world, also enabling many critical applications that require the reliability of the received signals. However, it is well known that the power of the GNSS signals at the receiver's antenna is extremely weak, and radio-frequency interference affecting the GNSS bandwidths might lead to reduced positioning and timing accuracy or even a complete lack of the navigation solution. Therefore, in order to mitigate interference in the GNSS receivers and guarantee reliable solutions, interference detection and classification becomes of paramount importance. This paper proposes an approach for the automatic and accurate detection and classification of the most common interference and jammers based on the use of Convolutional Neural Networks (CNN). The input for the network is the visual time-frequency representation of the received signal, together with statistical features in the time and frequency domains. The time-frequency representation is obtained using both the Wigner-Ville and the short-time Fourier transforms. Moreover, the performance of the proposed method is compared using two different CNN architectures, AlexNet and ResNet. The effectiveness of the method is shown in two case studies: Monitoring and classification by a terrestrial monitoring station and from a Low Earth Orbit satellite (LEO). The results show that the proposed method has quite a high accuracy in detecting and classifying interference, even with low power, and can be implemented as a real-time tool for monitoring jammers.

Published: March 2023

A dynamic logic gate without switching power using an inductor!

A new dynamic logic gate that consumes almost no switching power is presented. The stored energy on the load capacitance is transferred to an inductor during logic evaluation and recovered back during precharge. Simulations indicate that such integrated logic gates are possible. They consume about three times less power compared to conventional CMOS or dynamic logic gates.
A New Technique for Programmable Very Low Frequency Filtering
Authors: Mathiazhagan Chakravarthy
Published: March 2023

A new technique for obtaining a very large time-constant integrated filter is proposed. The time-constant of the filter is made proportional to r0C, where r0 is the output impedance of a transistor. Since 1/r0 is proportional to the bias current, the filter cut-off frequency is linearly programmable. The technique is demonstrated ex- perimentally using a simple circuit.
Review of A Cultural History of Chemistry. Peter J. T. Morris and Alan Rocke, eds., Bloomsbury Academic: London, 2022

Published: March 2023

When presented with a new multivolume series on the history of chemistry, one cannot help but compare it to J. R. Partington's masterful four-volume A History of Chemistry. The new six-volume A Cultural History of Chemistry reviewed here, however, is really a different beast and should not be viewed as a simple attempt to update Partington's previous series. As highlighted by series editors Peter Morris and Alan Rocke in the Series Preface that begins each volume, "This is not a conventional history of chemistry, but a first attempt at creating a cultural history of the science." As such, this series brings together 50 contributors in an effort to present the first detailed and authoritative survey of the impact of chemistry on society, as well as how society has influenced and impacted chemical practice and thought. Spanning from the earliest applications of the chemical arts in antiquity up through the present, this cultural history is split into six volumes, each covering a specific time period, with the structure of each volume consistent throughout the series. As such, each volume begins with an introduction, followed by the identical chapter titles: Theory and Concepts; Practice and Experiment; Sites and Technology; Culture and Knowledge; Society and Environment; Trade and Industry; Learning and Institutions; Art and Representation. As a result, this gives the reader the choice of focusing on a specific time period within a single volume, or following a chosen theme across history by reading the corresponding chapter in each of the six volumes. Each volume concludes with both a Bibliography and an Index, with all six volumes providing a combined 1728 pages of material. Separate reviews for each of the six volumes are given below, followed by some concluding remarks about the overall six-volume effort.
Investigation of the changes in some elements that play an active role in MS disease
Authors: Kılıç Soner
Published: March 2023

Objective: In this study, we examined the role of several metals which extracted from the hair of patients who affected by multiple sclerosis (MS). The ICP-MS measurements were performed using an Agilent 7500 series. With this procedure, all elements can be simultaneously quantified.
Material and Methods: All studies were carried out at Kayseri City Hospital between August 9, 2021, and October 11, 2021. We measured five elements from hair in association with the clinical course in 40 male and female MS subjects, as well as 40 healthy volunteers, using 1 cm hair sections. Using a novel microwave digestion method coupled with ICP-MS, we were able to analyze large numbers of samples per day consisting of 0.5 g of hair in 5 mL of nitric acid. Following digestion, the aliquots were examined to determine the quantities of Hg, Pb, Cu, Cd, and Zn.
Results: The quantities recovered for all elements were in an acceptable certified value range of (97.60–99.49%). Cu, Zn, and Hg levels examined were higher in the patient group, and Cd and Pb were higher in the control group. In our patients, a positive correlation was found between age, Hg, Cd, Pb values, and the disability score of multiple sclerosis [EDSS], while there was a negative correlation between Zn and Cu values and EDSS. Additionally, female MS patients showed a higher average hair content than males for the elements studied. Both Cd and Hg levels in patients were increased compared to the controls. Lead content in hair is steadily increasing in individuals of two different age groups. Lead content in hair showed an increased trend with age in the 21-35 year and 36-60 age groups.
Conclusion: Our study shows some important changes and relationships with Pb. Also, it has been determined that the Pb element increases with age, and the Cd and Hg levels were noticeably different in the patient and healthy groups, and Cu and Zn values change in parallel. The study can be a guide for diagnosis and treatment of the MS.

Objective: Systemic inflammatory parameters are predictors of poor prognosis in COVID-19 patients. This study evaluated whether the prognostic nutritional index, which was also related to nutrition risk and other inflammation-based prognostic scores, was predictive of in-hospital mortality in COVID-19 patients.

Materials and Methods: This was a retrospective cross-sectional single-center study. Based on the exclusion criteria, 151 patients over 18 years old diagnosed with COVID-19 and hospitalized in the intensive care unit between March 2020 and December 2020 were eligible for this study. Multivariable logistic regression analysis was performed to evaluate the predictive value of the Glasgow Prognostic Score (GPS), Prognostic Index (PI), Prognostic Nutritional Index (PNI), and Systemic Inflammatory Index (SII).

Results: In the univariate analyses, age, diabetes mellitus (DM), chronic kidney disease, acute kidney injury, hypothyroidism, hospitalization stay, lactate dehydrogenase (LDH), aspartate aminotransferase (AST), D-dimer, ferritin, C-reactive protein (CRP), albumin, hemoglobin level, platelet count, urea, creatinine level, PNI, GPS were significantly associated with mortality. However, in the multivariable logistic regression analysis of the inflammation-based prognostic scores, only PNI was statistically significant in predicting in-hospital mortality (OR=0.83; [95% CI=0.71-0.97]; p=0.019).

Conclusion: PNI is a more useful and powerful tool among these inflammation-based prognostic risk scores in predicting in-hospital mortality in COVID-19 patients.

Walka o kapitał moralny w polu polskiej inteligencji. Wojciech Roszkowski jako aktor historii i teraźniejszości

The fight for moral capital among the Polish intelligentsia. Wojciech Roszkowski as an actor of history and the present

The publication of Wojciech Roszkowski’s textbook for high schools, Historia i teraźniejszość. 1945–1979 [History and the Present. 1945–1979], has led to the fiercest controversy over the place of history in Poland’s public life since Jan Tomasz Gross’ Neighbours. The aim of the article is to examine the debate surrounding the textbook, particularly taking into account Wojciech Roszkowski’s trajectory and position among the Polish intelligentsia. Firstly, I demonstrate that the textbook crowns the author’s journey from solitary activity as a writer in the opposition movement and solitary work in the underground, through the mainstream of the elites of the Third Polish Republic to the heterodoxy of the conservative counter-elites. Secondly, I place the textbook in the tension between the Polish intelligentsia and the world of politics. Thirdly, I reconstruct the romantic, highly polemical, lofty and doom-laden structure controlling the historical narrative of the textbook, which strikes at the dominant, orthodox, progressive beliefs of the Polish intelligentsia. In conclusion I argue that the debate surrounding the textbook has stemmed from the author’s exceptional position and trajectory, the fight within the Polish intelligentsia as well as the unique, “hot”, monumental and explosive narrative of the textbook.

This study aims to look at the relationship between personal factors and purchasing decisions for Kampung chicken meat. Because the market is a place for the implementation of the demand and supply processes, it is able to provide products that are in accordance with buyer requests. This research was conducted in Padang city, West Sumatra, to be precise, at the Padang City Market, which is the central market of this area. The research was carried out in September 2022. The sampling technique used was the convenience sampling technique, and the number of samples was 100 people. The research instrument employed closed questionnaires with research variables such as age (X1), education (X2), family size (X3), income (X4), and purchasing decisions (Y). The Spearman rank test was used to analyze data using non-parametric statistical tests. Through the results of the study, it was found that only education had a close relationship with purchasing decisions. Other factors such as age, the number of family members, and income do not have a close relationship with purchasing decisions. The absence of a significant relationship can be influenced by factors outside the factors studied.

Published: March 2023

Mass vaccination against pertussis in our country has decreased the frequency of this infection. The lack of the total vaccination in children in 80-90 yy XX c led to the growth of morbidity in the current moment. Return in active vaccination / revaccination of population against pertussis is a demand of the time. Economic aspects of this kind approach to the social health care are required for an evaluation based on RWD.

Materials and methods: Calculation of the macroeconomic effects of vaccination against pertussis has been performed with Far East Federal Region (FEFR) example for buster in children 6-7 y. o. based on RWD and prognosis of morbidity annually. A unique model of the epidemiology of pertussis in FEFR has been created with RWD statistics and the Global burden of diseases project usage. The size of the virtual cohort of children 6-7 y. o. was established as 100 thousand. It has been assumed that 95 % from this cohort will receive buster of the tetanus toxoid, reduced diphtheria toxoid and acellular pertussis vaccine, combined, adsorbed (INN) with its efficacy and cost consideration. The monetary equivalent of the epidemiologic benefit due to disease prevention in the vaccinated children with regional GDP per capita has been calculated.

Results: The total summarized benefit due to illness prevention after buster in children in FEFR could be as 21,15 mln RUR annually, and due to mortality reduction in the life years expectation horizon — of 50,45 mln RUR. The total economic profit of the buster revaccination against pertussis in children 6-7 y. o. with its influence on morbidity in children of younger age groups can lead to 198,69 bln RUR during the 7-year horizon of vaccine efficacy.

Conclusion: RWD is a base for modeling and potential prognosis of epidemiological process and results of this job are proved the economic necessity for buster vaccination against pertussis in children 6-7 y. o. in the Russian Federation.

In a paper, surfaces, recommended for forming hull shapes of river and see ships, are supposed to use in architecture and building construction. These surfaces contain the given main frame from three plane curves in the form of superellipses. The presence of three overall dimensions and six arbitrary exponents in explicit and parametric equations of presented surfaces gives an opportunity to have large quantity of diverse forms of these surfaces, having only three equations. Designers must choose the most optimal surface taking into account architectural demands and strength conditions. In a paper, it is shown and illustrated the principles of geometric modeling of middle surfaces of thin shells of the offered type and an opportunity of their static analysis with the help of FEM is presented.

Published: March 2023

Mathematical modeling and experimental study of the inverse Cauchy problem of restoring the initial parameters of the elastic line of a beam element of a building structure for given minor coefficients of the beam deflection equation are considered. With a uniform continuous absolute norm of error for measuring deflections by interpolating with a Lagrange polynomial, the distribution of deflection meters over the beam is obtained, which minimizes the error in restoring the initial parameters by the criterion of minimum of the Lebesgue function.
