Authors: Kusuma Daniel Satya
Published: February 2025

In its operations, PT Saudara Sukses Abadi is a service company that operates in the logistics sector or tracking company. In the company's operational activities, there are often several orders that come in regularly and need to be delivered to certain target areas with various location objectives. Often companies combine cargo from several orders so that container trucks can load several travel orders for varied destination locations without reference to travel considerations so that the distance traveled by container trucks is less efficient and effective. Based on these problems, the suggestion or input that can be considered is to create a network between locations and mapping the location of the optimal delivery range network for the company by considering the distance between locations or destination points to be traversed in ongoing operations. The approach or optimization method used is the Minimum Spanning Tree method to cover the location of the entire network area that is the company's travel destination with consideration of the closest mileage. In carrying out this optimization, POM - QM application assistance and Matlab software are used to support data processing in terms of accuracy, to visual depiction so that it can be input or consideration for companies in carrying out shipping operations and logistics trips.

Tumor necrosis factor alpha (TNF-α) is a key pro-inflammatory cytokine in rheumatoid arthritis (RA) pathogenesis, with its
overexpression driving systemic effects characteristic of RA [1, 2]. Targeting TNF-α with biologic therapies has revolutionized RA
management [3, 4], highlighting its role in disease progression and severity. Our study revealed that monocytes from patients with RA
exhibit lower activation thresholds for TNF-α compared to healthy donors.

One of the methods forstudying the viability of cell spheroids isthe MTT test. However, this test does not permit the determination
of the number of viable cells within the spheroid at different stages of cultivation. Instead, it provides an indirect indication of the metabolic
activity of cells. In this study, we propose a method for estimating the number of viable cells in a cell spheroid using the MTT test.

Objective: To report a case of a Mixed Connective Tissue Disease (MCTD) that mimicked lymphoma during the diagnostic investigation. Case details: A 44-year-old woman was referred to a hospital with suspected lymphoma. She presented with a one-month history of lower limb weakness, accompanied by left lower limb paresthesia, asthenia, Raynaud's phenomenon, and a six-kilogram weight loss. Physical examination revealed an emaciated appearance with microstomia, reduced facial expression marks, sclerodactyly, skin thickening in the upper limbs, muscle weakness in all limbs, and lymphadenopathy in the left cervical and inguinal regions. Pulmonary auscultation revealed crackles at the lung bases. A PET-CT scan revealed increased uptake in the lymph nodes. During hospitalization, the patient tested positive for Anti-RNP antibodies, and the immunohistochemical analysis of a lymph node biopsy showed a reactive pattern. Based on the clinical and laboratory findings, a diagnosis of MCTD was made, and appropriate treatment was initiated. After six months of treatment, a new PET-CT scan showed the disappearance of the affected lymph nodes. Final considerations: MCTD is a rare, complex condition that can mimic other diseases, such as lymphoma, making early and accurate diagnosis essential.

Intraluminal Migration of Pelvic Drain Following Palliative Colonic Resection: A Rare but Risky Complication
Authors: S I Thejashwini , Pai Srinivas , Patil Veerendra A
Published: February 2025

Enhanced recovery after surgery (ERAS) protocols discourage drains after colorectal surgery as there are potential complications. However, sometimes, a drain is placed based on the surgeon’s decision. Our report highlights a case of carcinoma rectosigmoid; in his late sixties, he underwent palliative resection due to intestinal obstruction. We noticed faecal discharge in the drain, which gradually reduced. On per-rectal examination on day 15, we could palpate the drain. An emergency laparotomy was done, and we found that the drain had migrated through the anastomotic line and entered the lumen of the rectum. The drain was removed, and the breach in the anastomotic line was closed primarily, and a diversion ileostomy was performed. Discretion is needed before drain placement during surgery as there is a potential risk of migration of the drain through the anastomotic line. The aim of this report is to highlight this risk.

Published: February 2025

We report a series of six cases of cystitis cystica confirmed on histopathology, who presented to the urology centre of the tertiary care hospital between September 2023 and July 2024. Clinical examination revealed bilateral digital clubbing of both upper and lower limbs in all cases (Range grade 3 to grade 4). All patients belonged to the male gender aged between 24 years and 43 years. None of them gave a family history of clubbing. Two patients gave a history of having spent time in the high-altitude area (more than 2400 m above sea level) at the time of presentation. None of them displayed cyanosis or any other clinical features of chronic heart or lung diseases. All of them had normal chest X-rays, electrocardiogram, and ultrasonography of the abdomen. The acute phase reactants, biochemical and haematological parameters were within normal limits in all cases. Vascular endothelial growth factor and platelet-derived growth factor may be postulated as the common denominator in the association between clubbing and inflammatory changes in cystitis cystica. The association of cystitis cystica and digital clubbing has not been reported to date. This serendipitous correlation warrants further observation to authenticate the association.

В статье предложен анализ преимуществ и недостатков известных структурных редакторов, их функциональные возможности и производится оценка эффективности работы в сравнении с классическими текстовыми редакторами. Структурные редакторы отображают исходный код программы в виде иерархии. Редактирование в данном случае ограничено таким образом, что только корректные состояния возможны (код всегда соответствует грамматике языка программирования).

Introduction. Currently, a lot of software developers employ text editors to edit the source code of software projects. In this case, the developer works with symbols and strings of a source code. Source code editors are the main part of integrated development environment (IDEs). The development of software languages and environments has fostered the concept of displaying the syntax tree directly on the screen. It has led to the development of structure editors. Structure editors display the source code of the program in the hierarchical form. Editing in this case is limited in the way that only the correct states are possible (the code always corresponds to the programming language syntax). The hierarchical structure of the source code is described by a model, that is also referred to as CodeDOM. It is an abstract syntax tree or an intermediate representation of the source code. Such program representation, based on parse trees, has both advantages and disadvantages. The aim of the research was to analyze the functionality of structure editors, highlight their advantages and disadvantages and compare them with the typical approach to editing the source code presented in the text form. The studies outcomes allowed to describe a typical text editor architecture and its advantages and disadvantages. The principles of designing integrated development environments with structure editing support are presented. The main disadvantages of structure editors that limit their usage in the industrial software development are discussed. For the drawbacks in question we proposed solutions that could improve the software development process in the structure editors. The analysis of the structure editor architecture allowed to propose a model of integrated development environment with structure editing support, that simplifies the process of development environments designing and reduces the system response time. It is reasonable to carry out further research into the development environments with the structure editing support for the stateoftheart programming languages with a strict type checking such as C , Java, and Go. Conclusions. Paper presents the findings of the research into the analysis of functionality of structure editors, as well as the original model of the integrated development environment.

Introduction. Currently, a lot of the existing radio systems are data transmission systems. At the reception terminal, a mixture of signals is received with various distortions, which are considered as interferences and are compensated. However, these signal distortions contain a large amount of information about the environment where system operates. Using this information, one can get additional data on all the signals and improve the characteristics of radio communication systems. Problem statement. The paper discusses the solution to the problem of developing a test facility operating in the acoustic range within the information field for navigation of mobile passive objects. In this paper, the information field is considered as the field of all physical signals (electrical, acoustic, electromagnetic, optical) that exist in a certain area of space, which contains information about data flows in real time, characteristics of the propagation medium, interactions and locations of objects. To navigate the objects of the information field in the room, a local Cartesian coordinate system and a rangefinder method for determining coordinates were selected. The distance to the object is determined by the delay time of the signal propagation between the objects of the information field, measured by the correlation method. Development of the test facility. There is discussed the development of the test facility. An information field is created in a laboratory with an area of 15 m2by four "own" fixed objects, and the reception and analysis of signals is carried out by "own" fixed passive object. Based on the Virtex5-LX30 field-programmable gate array, which is part of the NI-PXI-7841R module, with the use of the Verilog language, a device for generating, receiving and processing information field signals has been developed. The acoustic signal receivers and transmitters were built with the use of Murata MA40S4S and MA40S4R sensors, respectively. The places of the objects in the laboratory was planned. Analysis of the efficiency of using information field for object navigation was carried out by calculating the delays of the information field signals with the use of a device developed on the basis of Virtex5-LX30, followed by calculating the distance to each active object, the coordinates of the passive object, as well as evaluating their deviations in the Matlab framework. Conclusions. With the use of the developed test facility, the operation of the system was verified and estimated deviations of the coordinates of the passive object did not exceed the theoretically calculated values.
ВЛИЯНИЕ РАЗВИТИЯ КРОНЫ НА РАДИАЛЬНЫЙ ПРИРОСТ РАННЕЙ И ПОЗДНЕЙ ДРЕВЕСИНЫ СТВОЛА ДУБА ЧЕРЕШЧАТОГО
Authors: Каплина Н.Ф.
Published: February 2025

Для деревьев раскидистого типа развития кроны (по оригинальной классификации) характерно формирование трёх рядов сосудов ранней древесины, зонтиковидного типа двух рядов, узкокронного типа одного ряда (ширина ранней древесины в нагорной дубраве соответственно: более 0,75 мм, 0,40,75 мм, менее 0,4 мм). В случае равного прироста поздней древесины прирост ранней больше у деревьев с более развитой кроной. В благоприятный период роста корреляция между приростом ранней и поздней древесины отсутствовала, в неблагоприятный была значима у деревьев со средне и слабо развитыми кронами, вероятно, изза ограничения восходящего тока.

Introduction. Conjugated analysis of the dynamics of radial stem increment and tree crown development allowed us to establish the principles of retrospective estimation of growth, development, and longterm state of tree and forest stand. The purpose of the work was the determination of stem increment indicators useful for identification of the development of crown type of Quercus robur trees. Results. Object of research was the upland artificial forest of the first site class, located on the southern border of the foreststeppe zone. Three types of oak crown development (original classification) were distinguished. Indicators of radial increment were defined from the scanned images of cores. For the trees with spreading crown formation type three rows of early wood vessels, for the umbrellalike crown type two rows, and for the narrowcrowned type one row is typical (early wood increment is respectively: more than 0,75 mm, 0,40,75 mm, less than 0,4 mm). In case of equal late wood increment the early wood increment was on the average higher for the trees with more developed crown. During the favorable growth period the correlation between early and late wood increments was absent, in adverse growth period the correlation was significant at trees with medium and poor crown development, due to probably ascending stream limiting.

Данные праймеры могут быть рекомендованы для молекулярно-генетических исследований берёзы повислой (Betula pendula).

Introduction. To use the molecular markers successfully, it is obligatory to select carefully the type of DNA marker and the particular primers used in the polymerase chain reaction. To solve the considered problem, it is necessary to conduct the preliminary research to detect the most informative DNA markers that allow determining the deepest polymorphism of the studied object. The goal of the research is to assess the level of variability of SSR and iPBS markers, and select the most informative primers for the genetic research of betula pendula. Six pairs of SSR primers and 14 iPBS primers were the object of the research. The methodology of the research included the following actions, implemented consistently: performance of polymerase chain reaction (PCR) with all the primers, visualization of PCR results using the electrophoresis, definition of the length of alleles of SSR loci in SSR analysis and PCR fragments using the iBPS primers, calculation of genetic polymorphism figures. Research results. The tested SSR and iPBS primers substantially differ in terms of the level of polymorphism. Number of the observed alleles for different SSR-locuses varied from 4 to 14 the observed heterozygosity was 0.38-0.88 the expected heterozygosity - 0.56- 0.89. The values of indicators of genetic polymorphism of 12 iPBS primers for Betula pendula were defined for the first time. The following figures for the indicators of variability (number of PCR fragments 717, number of polymorphic PCR fragments 317 share of polymorphic loci 42.9100.0 number of observed alleles 1.432.00 expected heterozygosity 0.140.34) were typical for the iPBS. Conclusion. To conduct the genetic analysis, it is necessary to use, above all, the primers that allow revealing the deepest polymorphism of betula pendula. Using the studied SSR primers L1.1, L2.3, L5.4, and L7.8 the SSR loci were found to have had the largest number of alleles (8 -14). Among the tested iPBSprimers, iPBS2076, iPBS2078, iPBS2232, and iPBS2271 primers are of greatest interest, application of these primers made it possible to reveal from 10 to 17 polymorphic PCR fragments.

Introduction. Low efficiency of Russia’s timber industry is much triggered by poor managerial and economic planning of the technological timber harvesting processes. One of the major measures that can contribute to improving of efficiency and quality of wood is to develop new technical solutions in terms of man-machine interaction, as well as to educate skilled operators to work on forest machines. Thus, practice-oriented methods with explicit use of training devices, simulators, and technological complexes are effective while training the operators of forest machines. At that, we face the challenge to define the structure and purpose of such simulators, and a set of simulated parameters. The objective of the study is to analyze and identify the parameters of the technological process feasibility and efficiency in the form of a dataset for a harvester simulator designing. Objects and methods. The paper scrutinizes the major factors that influence the efficiency of timber cutting production. Moreover, it gives the interaction structure between a human operator and a forest machine from the perspective of ergatic systems, and its key elements are specified. Results. The paper describes the models of a tree, a technological field, and a forest machine that have been designed with the use of the method of structural and semantic analysis. The models are given in the form of a parametric data structure, which are further used as the main parameters for the simulation training environment, each system parameter is described by the respective pattern of change. Conclusion. The designed parametric models make it feasible to define the initial and border-line conditions of each parameter that changes in the simulation process; to lower the requirements for computing capacity; and finally, to ensure a greater similarity of the simulated technological process to true-life actions of the operator in the physical world, that is, to make the training environment immersive. Moreover, the proposed models ensure adequacy, dynamism, and variability of changes in the parameters of the environment, the technological field, and the job task. The models can be applied in simulators for forest machine operators’ training.

Published: February 2025

Организация надёжного лесовосстановления – важная задача лесной отрасли. Одним из путей решения этой задачи является технология лесовосстановления с применением посадочного материала с закрытой корневой системой. Такая технология имеет ряд преимуществ, по сравнению с использованием посадочного материала с открытой корневой системой. Традиционно контейнеры производятся из различных видов пластика. Предложено изготавливать контейнеры из экологически безопасных, биоразлагаемых древесно-цементных композитов, в основе которых лежат древесные опилки и гидравлическое вяжущее. Древесно-цементные композиции имеют высокие механические показатели и пригодны для производства биологически разлагаемых лесопосадочных контейнеров. Использование древесных отходов лесопиления при производстве таких контейнеров позволяет попутно решить проблему утилизации этих отходов, снизить пожарную опасность. В процессе исследований были определены механические свойства композиционных материалов на основе опилок и вяжущих веществ (цемент и меласса), а также прочность, водопоглощение и морозостойкость. Выявлено, что лучшими показателями для прессования лесопосадочных контейнеров обладает смесь на основе опилок, цемента, жидкого стекла, песка и сульфата алюминия. Полученные результаты и закономерности могут быть использованы при дальнейших исследованиях в области материалов и технологий для лесовосстановления.

Introduction. Forest regeneration with the use of the containerized seedlings is a modern trend in reforestation. The technology has several advantages compared to planting of bare-rooted seedlings. But this technology requires containers for seedlings. Traditionally, containers are made of various types of plastics. The goal of the research is to study the process of pressing of biodegradable containers made of wood-cement composites. Results. Mechanical properties of composite materials based on sawdust and binders (cement and molasses) were determined. Strength, water absorption, and frost resistance were also defined. The authors found out that the mixture based on sawdust, cement, liquid glass, sand, and aluminum sulfate showed the best performance for containers pressing. The dynamics of the decrease in the strength of wood-cement composition in the soil was established. When pressing, the strength index of containers decreases from 3.36 to 1.65 MPa (for 42 months). The root system of seedlings in the process of its development will successfully go beyond the container and continue to grow and develop. Conclusion. The possibility for manufacturing of containers of wood-cement composites is grounded. The obtained results and patterns can be used in further research of materials and technologies aimed at reforestation.

Introduction. Recently, more attention is paid to the study of biologically active components in the wild vegetation of our forests. Wild plants contain a wide range of secondary metabolites, that is, they are good contenders as functional food. In traditional medical and pharmaceutical practice, freshly harvested plant raw materials are not of a widespread use. It is mainly due to the impossibility of their long storage and the need for rapid processing after collection. It is necessary to conduct research on the safety of biologically active substances, depending on the methods of storage and processing. The goal of the research is to study the biochemical composition of the berries of the Vaccinium genus, depending on the degree of their processing and to choose the optimal method of preserving medicinal raw materials for maximum preservation of biologically active substances. Results. Based on the obtained results, the conclusions on the optimal ways of processing of berry plant raw material in order to preserve the metabolites were drawn. Conclusion. The research found that fresh fruits of wild berry fields had the richest composition of biologically active substances. The main methods of preservation (drying and freezing) have both advantages and disadvantages as the decrease or loss of biologically active substances and, together with it, pharmacological properties of medicinal plant raw materials takes place. The authors analyzed all the methods of processing and storing of medicinal plant raw materials, and set a task to determine the method of conservation that best preserved biologically active substances. Comparing the data obtained, the authors came to the following conclusion: 1) total sugars were preserved better in freezing; 2) total organic acids were better preserved when drying of berries; 3) the amount of anthocyans increased when drying of berries; 4) arbutin was preserved better when drying of berries; 5) the amount of vitamin C was greatest when frozen; 6) the amount of pectin remained large when drying of fruits. Based on the results of the experiment, drying can be considered to be the most optimal method for preserving biologically active substances in fruits of cowberry and blueberry and shall be recommended for use.

Authors: Haryati Sani
Published: February 2025

This study aims to evaluate the financial performance of PT Unilever Indonesia Tbk. based on profitability ratios, namely Return on Assets (ROA) and Return on Equity (ROE), and their impact on the company's stock price. The data used include quarterly financial reports and stock prices of PT Unilever Indonesia Tbk. from the first quarter of 2020 to the third quarter of 2024. The research method employs multiple regression analysis with hypothesis testing conducted through t-tests (partial) and F-tests (simultaneous). The results indicate that, partially, ROA has a significant effect on stock price, with a significance value of 0.019 (< 0.05) and a t-value of 2.606 exceeding the t table value of 2.131. Conversely, ROE does not significantly affect stock price, as evidenced by a significance value of 1.563 (> 0.05) and a t-value of 0.634, below the t table threshold. Simultaneously, ROA and ROE significantly influence stock price, with an F-value of 4.403 exceeding the F Table value of 3.68 and a significance value of 0.030 (< 0.05). The contribution of ROA and ROE to stock price variation is reflected in an R2 value of 0.355, indicating that 35.5% of stock price changes are explained by these variables, while the remaining 64.5% are influenced by factors outside the study. These findings recommend that the company continues to enhance asset utilization to optimize ROA, which has proven significant in affecting stock price. Additionally, future researchers are advised to consider other variables, such as capital structure, dividend policies, and market conditions, to provide a more comprehensive understanding of the factors influencing stock price.
