AN APPROACH TO DECISION SUPPORT FOR CHOOSING A TELECOMMUNICATIONS EQUIPMENT SUPPLIER BASED ON AGGREGATION OPERATORS
Authors: Sakulin S. A. , Alfimtsev A. N. , Bobretsova A. G.
Published: September 2024

In the conditions of rapidly changing market environment and an increase of volume of information that requires analysis and processing before making decisions, the task of creating effective decision support systems is becoming increasingly urgent. These systems allow to reduce the time required for data analysis and development of optimal solutions, as well as to increase the accuracy of decisions made. However, most decision support systems are based on classical methods of multicriteria analysis, which have their limitations and disadvantages. This can lead to incorrect decisions and reduce the efficiency of the system. To improve the accuracy and efficiency of decision support systems, this article suggests using the criteria aggregation operator based on the Choquet integral. This method allows you to take into account all the factors influencing decision-making and objectively assess their significance. The article discusses in detail the process of normalization of criteria and identification of a fuzzy measure. There are also specific examples of expert assessments for the criteria that are used when choosing a supplier of telecommunications equipment. Based on these data, suppliers are evaluated and a decision is made to choose the best one. The evaluation results demonstrate the high efficiency of the method and allow us to conclude that the criteria aggregation operator based on the Choquet integral is an effective tool for decision support in conditions of high information load and uncertainty in the market.

Published: September 2024

In accordance with the trend in further intellectualization of mapping data design systems, this article deals with the problem of development methods for obtaining aerodrome mapping data more efficient than the existing methods that use manual vectorization on a raster base. Data usage areas were listed, including automated control systems, flight deck automation, simulators and simulation systems. Much attention was given to main aerodrome mapping data design approaches analysis, which shows that existing aerodrome cartographic data obtaining methods lack functionality. A description and basic requirements for an aerodrome mapping data design system, as well as requirements for the data itself, are presented. Additionally, data validation aspects are noted, including those of a taxi route network. Results of the research suggest that computer-aided design methods make it possible to significantly reduce labor intensity and time required to obtain mapping data. A new approach, which consists in using computer-aided design methods for such data, is proposed. Areas in which this approach can provide a significant effect were identified. Methods, algorithms and programs that implement the approach are being developed in context of the new data design system. It will provide a wide range of functions for aerodrome mapping design. General scheme of the system describing its main components was given. An example of aircraft parking elements design as a part of routing network design is provided.

The management of all processes is based on decisive rules. The quality of these rules largely depends on the completeness and quality of the data used for their creation. A serious problem in data preparation is the presence of missing values. Filling in missing values is commonly referred to as data imputation. There are various methods for solving this problem. Existing methodologies for selecting the most suitable imputation method are well applicable for analyzing large amounts of data, but they are difficult to use for relatively small datasets. In this case it is suggested that the final purpose of the imputed dataset should be considered. For example, if the ultimate goal is to solve a classification problem, then imputation methods should be considered in combination with classification methods, and the best combination should be chosen based on classification method metrics, but without overfitting. The authors' approach is demonstrated on real data for diagnosing two common diseases: hypertension and hypotension. The input parameters considered were age, body mass index, and 28 blood biochemistry indicators. Missing values were filled in using six methods. After imputation, the general sample of 502 observations was split into training (80 %) and testing (20 %) sets. For solving each classification problem, 18 machine learning models were used. The calculation results are presented.

Published: September 2024

Privacy violations and misuse of customer data are the failures of Web 2.0. Web 2.0 employs a centralized server that can be accessed by authorities. With the development of Web 3.0, which is built on blockchain and uses a decentralized application (dApp) to avoid privacy violations and data misuse. Decentralized systems can offer users privacy and autonomous control of the system, which is an important feature of consumer protection. Decentralized web development, also known as Web 3.0, was created using blockchain technology and the peer-to-peer network protocol (IPFS). In a decentralized website environment, data on the server can be linked to conventional domains (.com, .id, etc.) or to special domains provided by blockchain-based platform domains. Every transaction must be linked to the Ethereum wallet and cryptocurrency for the smart contract to function. This activity takes a long time and is a bad UX for decentralized web developers. To compare the performance of a decentralized web using blockchain DNS and a centralized web using conventional domains, a 15-minute usage scenario with a maximum of 50 users is used. The results show that the throughput and bandwidth of a decentralized web is higher than a centralized web.

A polyphagous nocturnal pest Spodoptera litura (Fabr.) commonly called armyworm, infests about 150 plant species across 44 families worldwide, with nearly 60 plant species affected just in India. The majority of leaf tissues are consumed by the larvae and only the stem and side shoots will remain in the field. They entirely consume the interior content by boring into them, causing squares and young bolls to shed. This insect can badly affect crops and has a wide range of potential hosts, which can lead to financial losses for farmers and food shortages for consumers. The worldwide distribution of S. litura as a pest results in significant impact on productivity of many crops. They have the capability to invade new places as a wide-ranging species. Armyworm frequently reappears in India every year and causes evident destruction. Different records on the insect population outbreak have been reported from many countries all around the world. The larvae of insect pests enter the fruits and even contaminate it and this causes yield and economic losses. The low temperatures of winter season are the limiting factors that affect species. It migrates mainly to breed during the summer season but is unable to survive in winters. S. litura acquired resistance to several synthetic insecticides, which led to pest outbreaks that were irregular and caused failure of different crops. The resistance and cross-resistance of this pest against insecticide toxin make it more difficult to reduce its population below threshold level. Understanding the mechanisms of resistance is crucial for developing effective resistance management strategies that can restrict or halt the spread of resistance in these pest populations.

Objective We monitored cognition in 14 Parkinson’s disease (PD) patients during deep brain stimulation (DBS) surgery when the electrode was positioned at the target subthalamic nucleus (STN) (i.e., the STN motor area).Methods We present the DBS-real-time neuropsychological testing (DBS-RTNT) protocol and our preliminary experience with it; we also compared the intraoperative patient performance with the baseline data.Results Compared with the baseline data, patients undergoing DBS-RTNT in the target area demonstrated a significantly decreased performance on some tasks belonging to the memory and executive function domains. Patients undergoing right hemisphere DBS-RTNT had significantly lower short-term memory and sequencing scores than did patients undergoing left hemisphere DBS-RTNT.Conclusion PD patient cognitive performance should be monitored during DBS surgery, as STN-DBS may induce changes. These preliminary data contribute to improving our understanding of the anatomo-functional topography of the STN during DBS surgery, which will enable the identification of the best site for producing positive motor effects without causing negative cognitive and/or emotional changes in individual patients in the future. In principle, medications (i.e., patients who underwent surgery in a levodopa-off state) could have influenced our results; therefore, future studies are needed to address the possible confounding effects of levodopa use.
Der gut strukturierte Tod
Authors: Baur Kilian
Published: September 2024

Abstract

Based on the example of King Conrad I’s death, this paper wants to contribute to the question of how medieval historiography chose and arranged its contents. It postulates that chroniclers narrated their histories just like medieval authors of fictional literature by using plot schemes. Before King Conrad I died, Ottonian sources tell us, he had called for his brother and designated the Saxonian Duke Henry I king. Former research saw vast similarities between the sources as either evidence for their reliability, as textual references, or regarded them as written result of an oral tradition at the Ottonian court. A comparison with several ( East-/West- ) Franconian and English narratives about other rulers’ deaths ( e. g. Pepin the Younger, William the Conqueror or Saladin ) shows us that not only Ottonian, but chroniclers in general used the same textual elements, which they arranged in a similar order. One reason for this might be references to the Bible and hagiography. However, since there are no obvious linguistic borrowings tangible between the narratives, the death of Conrad I in the Ottonian sources can be interpreted as a variation of narratives, based on a more widespread scheme used probably all over Latin Europe. This scheme was distributed in different ways: by the use of textual models, but also by the adaption of oral narratives.

Focusing on the needs related to the selection of sources and literature for text verification, it also presents the interdependence of Orthodox hymnography and the texts of the Holy Scripture. As a result, a set of necessary activities in editorial work was presented, which can be used not only when working on the Psalter, but can be helpful when editing other liturgical books.
„To czyńcie na moją pamiątkę!” Wschodnie a zachodnie rozumienie anamnezy eucharystycznej
Authors:   Wydział Teologiczny, Uniwersytet Papieski Jana Pawła II w Krakowie, Kraków, Polska, Kaleciak Szczepan
Published: September 2024

The concept of liturgical anamnesis refers to the remembering of God's acts, which makes them present and actualised in every celebration. Both Latin and Orthodox theology emphasise the anamnetic dimension of liturgical celebration. However, there are important differences between individual liturgical practices and their theological understanding. This article attempts to explore the nature and extent of these differences. Are these merely different formulations due to distinct liturgical traditions and practices, or do the differences concern the essence of the understanding of the Eucharist as a memorial? In order to answer this question, the first part of this article will discuss the biblical understanding of the concept of anamnesis, which is common to both Latin and Eastern theology. This will be done using the historical-genetic method. In the second part, the understanding of anamnesis in the Latin Church will be presented as it results from an analysis of the Eucharistic Prayers used by that Church. For this purpose, the author will employ the method of analysis and interpretation of liturgical texts. The third part will attempt to characterise the Orthodox theology of anamnesis.
Теория и практика «политического исихазма» в России в XXI веке
Authors:   Akademia Ekonomiczno – Humanistyczna w Warszawie, Polska, Słomski Wojciech
Published: September 2024

The article is devoted to the revival of the so-called “political hesychasm” in the Russian Federation in the 21st century. The key document defining the church’s attitude to politics, society and the state is the “Fundamentals of the Social Concept of the Russian Orthodox Church”, adopted at the Church Council in 2000. The purpose of this article is to clarify the conception of “political hesychasm” by analyzing the “Fundamentals of the Social Concept” and researches published on the issue, as well as to assess the implementation of this conception to modern political and social processes, through comparative and component analysis. The Concept seemed revolutionary for the Russian traditions of relations between church and state. For example, if the state causes citizens to sin, they are called upon to engage in civil disobedience against the sinful state. Participation in government and political activities is permitted only if these activities do not contradict the Christian faith. However, in practice, as the authoritarian regime in Russia strengthened, the Moscow Patriarchate, contrary to its social concept, became dependent on the authoritarian regime and began ideologically serving the political authorities, which contradicts not only hesychasm, but also the very essence of Christianity.

Increasingly, Semarang City is experiencing significant MSME business growth. Judging from the economic, social, and environmental problems in this city, everyone is competing in advancing their region. With MSMEs, there are various entities that benefit, such as business owners and other people. These benefits can be in the form of financial benefits that can be a solution to problems in Semarang City, namely poverty and unemployment. The more income-generating entities, the faster economic problems are resolved. Therefore, a forum is needed that can be a place for business people, both old and new business people, to improve their therapy in business. The architectural planning and design program carried by the author is the design of "Semarang Business Incubator and Commercial Space Center with  Sustainable Architecture Design Approach". Sustainable Architecture was chosen because in planning a building must have the concept of sustainability by managing waste and utilizing resources optimally. In addition, the use of environmentally friendly materials can also keep the ecosystem around the building maintained and unpolluted. Therefore, this building is expected to be the spearhead in overcoming three main problems in Semarang City, namely, economic problems, social problems, and environmental problems which if not immediately addressed will become a boomerang for the government and citizens of Semarang City.

Published: September 2024

The increasing number of drug abuse cases in Indonesia, particularly among teenagers, indicates that government prevention measures have not been fully effective, as many areas lack adequate rehabilitation centers. These centers are essential for helping victims recover from addiction and reintegrate into society, serving both rehabilitative and preventive functions. Banten Province has several rehabilitation centers, but not all meet the necessary standards. This underscores the need for a specialized Drug Rehabilitation Center focused on teenagers, who are the majority of drug addiction victims. This center will utilize the Therapeutic Community (TC) model, where rehabilitants engage in social rehabilitation activities within their communities, and employ a Behavioral Architecture approach, which responds to users and their environment. The planning and design of this center will involve the analysis of primary and secondary data through five aspects: functional, contextual, technical, performance, and architectural. The Behavioral Architecture approach aims to create spaces that support the physical and mental healing of teenage drug addicts while being responsive to their needs. The analysis results will guide the subsequent design process.
Less frequent radiological exams to avoid futile response assessments from 177-LuDOTATE therapy for patients with advanced neuroendocrine tumors
Authors: Marques Carolina C , Brito Angelo B , Lima Eduardo N , Donadio Mauro D , Riechelmann Rachel P
Published: September 2024

Background

177-LuDOTATE is an effective but expensive treatment for neuroendocrine tumors (NETs). Reducing treatment-related costs, such as the number of images, could improve access to 177-LuDOTATE. We evaluated early radiological tumor progression and prognostic factors in patients with NETs treated with 177-LuDOTATE.

Methods

We retrospectively included all patients with NETs who received at least one cycle of 177-LuDOTATE. The primary endpoint was the rate of early radiological progression between cycles 2 and 3 (in 10–16 weeks). Secondary endpoints were progression-free survival (PFS) and overall survival (OS) according to prognostic factors (tumor grade, primary site, functioning syndrome, 177-LuDOTATE treatment line) in Cox proportional hazards models.

Results

The median number of 177-LuDOTATE cycles was 3 (range 1–6) among 59 patients included. Ten (17%) patients had early progression. Among 14 patients who received ≤2 cycles of 177-LuDOTATE, ten (72%) stopped treatment due to disease progression, with five patients having a G2 (ki67: 5–25%) and 4, a G3 (ki67: 25–90%) NET. In the Cox multivariable analysis, higher grade (G2 or G3 vs G1) were significantly associated with inferior PFS and OS. The median PFS of G1, G2 and G3 NET patients were: 34.1, 11.7 and 6.1 months (P = 0.015), respectively.

Conclusions

It is feasible to perform imaging tests after 177-LuDOTATE completion for patients with indolent NETs with the intent to avoid futile assessments. For patients with more aggressive diseases, such as G3 NETs and G2 tumors with high tumor burden, we advise to perform more frequent images during 177-LuDOTATE therapy.

Проведены измерения газов, десорбированных вакуумным методом из колец спилов лиственных деревьев с использованием оптико-акустического газоанализатора с перестраиваемым СО2-лазером. Получены хронологии остаточных газов СО2 и (СО2 + Н2О) некоторых лиственных деревьев, произрастающих в районе г. Томска (Западная Сибирь). Хронологии характеризуются хорошо выраженными 2-4-летними циклами. Найдена корреляция содержания газов с летними температурами и осадками. Полагаем, что погодичное распределение остаточных газов в спилах отражает картину поступления газов из стволов лиственных деревьев в атмосферу.

Gases desorbed by the vacuum method from the tree rings of discs of deciduous trees are measured. The content of residual gases vacuum-desorbed from tree rings is analyzed with an opto-acoustic gas analyzer with a tunable CO2 laser. The chronologies of residual CO2 and (CO2 + H2O) of some deciduous trees growing near the city of Tomsk (West Siberia) have been derived. All the chronologies are cyclic with pronounced 2-4-year cycles. A correlation was found between the content of gases and summer temperatures and precipitation. We believe that the annual distribution of residual gases in the discs reflects the pattern of annual release of the gases from the stems of the deciduous trees into the atmosphere.

Приведены результаты гиперспектрального зондирования атмосферы на Уральской атмосферной станции в пос. Коуровка Свердловской обл. за период 2012-2022 гг. Показано, что средняя скорость роста СО2 в атмосфере данного региона составляет ~ 2,5 ppm/год. Двумя независимыми методами оценено количество поглощаемого из атмосферы углекислого газа лесной экосистемой на единицу площади за вегетационный период (апрель - сентябрь) в окрестности карбонового полигона в Коуровке. Первый метод основан на использовании данных о содержании СО2 в атмосферном столбе, полученных при зондировании атмосферы наземным ИК-Фурье-спектрометром высокого разрешения, а во втором методе применяется оригинальная нейросетевая модель, на вход которой подаются данные спектральных каналов спутникового сенсора MODIS. Полученные результаты демонстрируют хорошее согласие: количество СО2, поглощенного лесной экосистемой из атмосферы, в окрестности карбонового полигона за вегетационный период 2022 г. составляет ~ 1,5 т/га (первый метод) и ~ 1,3 т/га (второй метод).

The results of hyperspectral sounding of the atmosphere at the Ural Atmospheric Station in Kourovka from 2012-2022 are presented. It is shown that the average rate of CO2 growth in the atmosphere of this region is about 2.5 ppm per year. The amount of carbon dioxide absorbed from the atmosphere by the forest ecosystem per unit area during the growing season (April-September) in the vicinity of the carbon landfill in Kourovka is estimated using two independent methods. One method is based on the data on the CO2 total column obtained from sounding the atmosphere with a ground-based high-resolution infrared Fourier spectrometer. The second method is based on the use of an artificial neural network with data from spectral channels of the MODIS satellite sensor as injnit. The results obtained by both methods demonstrate good agreement. The estimates made show that the amount of CO2 absorbed from the atmosphere by the forest ecosystem in the vicinity of the carbon landfill site during the growing season of 2022 is about 1.5 t/ha (the first method) and about 1.3 t/ha (the second method).

Methodology study for determining the half-value layer using the Monte Carlo code PHITS
Authors: Soares Ronald , Lacerda Marco Aurélio
Published: September 2024

For most purposes, the quality of a beam can be specified in terms of the half-value layer (HVL), which is the thickness of material required to reduce the air kerma  to half, at one meter from the source, from a unidirectional beam of infinitesimal width. Just like many other radiological quantities of interest, the HVL can be estimated via simulations employing the Monte Carlo Method (MCM). Among the variety of MCM based codes available, the Particles and Heavy Ions Transport Code System (PHITS) was the one adopted in this study. Primarily, simulations were conducted to determine the X-ray spectra resulting from the interaction of electron beams with different energies with a tungsten anode. Each of these spectra was then defined as a probability distribution for the photon source energies in a second round of simulations, where it was possible to estimate the X-ray beam qualities as specified by the reference literature. At this stage, it was possible to estimate the mean energy of the beam  and the conversion coefficient for air kerma per unit fluence  for each of the qualities. The results obtained in this phase were used to define the sources for other groups of simulations, where the air kerma was quantified for each source configuration, for different thicknesses of an aluminum metallic attenuator, which was also done with spectra for the same X-ray beam qualities obtained from a reference catalog. Curve fitting on the scatter of kerma points as a function of attenuation allowed the estimation of the HVL. The results obtained are consistent with the values described in the literature and demonstrate the efficiency of the developed methodology, as well as the use of the code in the evaluated energy range for X-rays.

Tulisan ini merupakan kajian politik keamanan nontradisional yang berfokus kepada illegal fishing. Illegal fishing merupakan bentuk ancaman yang dapat merusak hubungan antar negara, lingkungan hidup, dan berdampak terhadap keamanan manusia. Tulisan ini berupaya menganalisis mengapa kasus illegal fishing oleh kapal ikan asing dan kapal ikan Indonesia di Provinsi Aceh sering kali terjadi. Kasus illegal fishing yang terjadi di Aceh dianalisis menggunakan pendekatan keamanan nontradisional dengan menggunakan Teori Sea Power Mahan. Metode penelitian yang digunakan adalah metode kualitatif dengan teknik pengumpulan data melalui wawancara mendalam dan studi pustaka. Penelitian dilaksanakan dari bulan Agustus hingga September 2022. Hasil dari penelitian ini adalah kasus illegal fishing terjadi disebabkan oleh faktor wilayah, masyarakat, dan pemerintah. Faktor wilayah seperti jauhnya Aceh dari pusat pemerintahan dan berada di wilayah perbatasan. Faktor dari masyarakat misalnya sedikitnya jumlah nelayan, adanya tradisi larangan melaut, dan masih menggunakan alat tangkap yang dilarang. Terakhir faktor pemerintah adalah rendahnya pengawasan, dan kebijakan yang tidak ramah illegal fishing. Title: Analysis Illegal Fishing in The Aceh WatersThis paper studies non-traditional security politics that focus on illegal fishing. Illegal fishing is a form of threat that can damage relations between countries and the environment and have an impact on human security. This paper analyses why illegal fishing by foreign and Indonesian fishing boats often occurs in Aceh Province. Cases of illegal fishing that occurred in Aceh were analyzed using a nontraditional security approach using Mahan’s Sea Power Theory. The research method used is qualitative, with data collection techniques through in-depth interviews and literature study. The research was conducted from August to September 2022. The results of this study are cases of illegal fishing that occur due to regional, community, and government factors. Regional factors include Aceh’s distance from the central government, and being in a border area. Aspects from the community, for example, the small number of fishermen, the tradition of prohibiting going to sea, and still using prohibited fishing gear. Finally, the government factor is the low level of supervision and policies that could be more friendly to illegal fishing.

Indonesia memiliki wilayah perairan yang luas dengan sumber daya perikanan melimpah yang dapat meningkatkan penerimaan negara khususnya dari penerimaan bukan pajak subsektor sumber daya alam (SDA). Dengan daya apung PNBP, responsivitas PNBP sektor perikanan subsektor SDA terhadap perubahan PDB dapat diukur. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi daya apung PNBP sektor perikanan subsektor SDA pada tahun 2002—2021. Penelitian ini menggunakan data sekunder yang diperoleh dari Kementerian Keuangan, Kementerian Kelautan dan Perikanan, dan BPS dengan metode analisis regresi Error Correction Model (ECM). Hasil penelitian menunjukkan dalam jangka pendek, nilai produksi perikanan dan reformasi PNBP sektor perikanan berpengaruh positif dan signifikan, illegal fishing berpengaruh negatif dan signifikan. Akan tetapi realisasi belanja KKP tidak berpengaruh signifikan terhadap daya apung PNBP sektor perikanan subsektor SDA. Dalam jangka panjang nilai produksi perikanan, realisasi belanja KKP, illegal fishing, dan reformasi PNBP sektor perikanan tidak berpengaruh signifikan terhadap daya apung PNBP sektor perikanan subsektor SDA. Sebagai rekomendasi, perlu adanya kebijakan yang terukur dan konsisten dilakukan dalam mendukung optimalisasi pemanfaatan SDA perikanan sebagai sumber penerimaan negara.Title: Analysis of Factors Affecting Buoyancy of PNBP in the Fisheries Sector of Natural Resources SubsectorIndonesia has vast territorial waters with abundant fishery resources which can increase state revenues, especially from PNBP of the natural resources. With the buoyancy of PNBP, the responsiveness of PNBP in the fisheries sector of natural resources can be measured against changes in GDP. This research aims to analyze the buoyancy of PNBP in the fisheries sector of natural resources from 2002 – 2021. This research used secondary data obtained from the Ministry of Finance, the Ministry of Marine Affairs and Fisheries, and the Central Statistics Agency, using the Error Correction Model (ECM) regression analysis method. The results showed that in the short term, the fishery production value and PNBP reform in the fisheries sector have a positive and significant effect, and illegal fishing has a negative and significant effect. However, the realization of KKP spending does not have a significant effect on the buoyancy of PNBP in the fisheries sector of the natural resources subsector. In the long term, the fishery production value, the realization of KKP spending, illegal fishing, and PNBP reform in the fisheries sector do not significantly affect the buoyancy of PNBP in the fisheries sector of the natural resources subsector. As a recommendation, there needs to be a measurable and consistent policy carried out in supporting the optimization of the use of fishery resources as a source of state revenue.
