Multicomponentity in German and Russian Composites
Authors:   National Research Nizhny Novgorod State University, Krupnova N.
Published: February 2025

The author of the article examined and described multicomponent formations consisting of two languages: Russian and German. The author conducts a comparative analysis of such composites, considering the multi-stage nature of the formation of their word-formation structure, identifying the main sphere of their functioning, and he also demonstrates the common and distinctive features of the phenomenon of polycomponentism in both languages. The study found that this phenomenon is more common and familiar for the German language, since giant words can also be found in the everyday speech of ordinary Germans. But they still became most widespread in the German language precisely in the field of legislation and official business style. For the Russian language, these formations are less typical. Their structure consists of fewer components compared to the German language. Also, they are often either outdated words or terms from different fields of science, in particular chemistry.

Published: February 2025

Sulangai Village experiences limited internet access due to its geographical condition in a mountainous area, so cable infrastructure such as fiber optics is difficult to implement. The proposed solution is to use point-to-point wireless networks to provide reliable internet access. The research method used is the Network Development Life Cycle (NDLC), including the stages of analysis, design, simulation, implementation, monitoring and management. The test results show that the signal strength at the Base Station and Client Station is -69 dBm each, which is in the very good category. Security testing using IPsec VPN and GRE also showed adequate results, with the ability to encrypt data and protect the network from outsiders. Bandwidth speed testing before and after security implementation shows stable and satisfactory network performance, with consistent transmission and reception speeds. The results of the Quality of Service (QoS) analysis also show a significant increase after implementing security, with good throughput, packet loss, delay and jitter values.

A Human Rights Perspective on Granting Privileges to Descendants of PKI in Indonesia
Authors: Susantijo Susi
Published: February 2025

Human rights, as inherent rights granted to all individuals by virtue of their existence, are enshrined in Law Number 39 of 1999 concerning Human Rights. In Indonesia, human rights remain a critical focus, particularly in addressing past gross human rights violations, which continue to be unresolved despite various regulations, including Presidential Letter Number 2 of 2023 and Presidential Decree Number 17 of 2022. These measures, aimed at non-judicial settlement of past violations, have sparked controversy, particularly regarding their compatibility with MPR Decree Number XXV/MPRS/1966. This research explores the challenges and implications of granting special rights to descendants of the PKI, raising the question of whether they are entitled to such privileges. The granting of these rights has provoked both positive and negative reactions within civil society, with the government's central policy seen as a step toward future improvements. Utilizing a normative legal research methodology, this research analyzes various sources such as books, journals, and newspapers, offering a comprehensive legal analysis. The research concludes that, under the principles of justice, benefit, and legal certainty, the Indonesian state’s provision of special rights to the descendants of the PKI is legally legitimate.
Assessment of the Seasonal Rainfall Forecast Skills of clWRF and RegCM Climate Models
Authors: Ngoc Thanh Pham , Quang Nam Pham
Published: February 2025

This paper evaluates the ability to forecast monthly and seasonal rainfall in seven climatic regions of Vietnam using the dynamical downscaling method, employing two climate models, clWRF and RegCM, with input data from the global climate model (NCEP CFSv2). The results indicate that the models perform best in the northern regions. However, significant forecast errors occur in the Central Highlands and Southern regions during dry months. The RegCM model provides more accurate rainfall forecasts in the North Central, South Central, and Central Highlands regions, while the clWRF model performs better in the Southern region. Forecast quality varies with lead times. At 5-month lead time, the models show considerably larger errors compared to 1- and 3-month lead times, particularly in September, October, November, and December in the Northwest, Northeast, and Red River Delta regions. Similarly, higher errors happen in January, February, November, and December in the other regions, while in March, April, and May, the models using 5-month lead time exhibit the lowest errors in these regions. The correlation between forecasted and observed rainfall remains low, emphasizing the complexity of seasonal rainfall forecast. Therefore, exploring post-model correction methods is needed to improve forecast quality.

A Study Comparing the Results of Diathermy Versus Scalpel for Inguinal Skin Incisions
Authors: Abhijith H. M. , Shafiuddin M.
Published: February 2025

Objectives

The advent of electrocautery has introduced a significant alternative to traditional scalpels for making skin incisions in surgical procedures. Electrosurgery, also known as surgical diathermy, involves passing high-frequency electric current through body tissues to achieve coagulation, fulguration, and cutting. There are two main types of diathermy: monopolar, where the current travels from an electrode near the target tissue to a fixed electrode elsewhere on the body, and bipolar, where both electrodes are on a single device, allowing the current to flow through the treated tissue alone. Despite the advantages of diathermy, including reduced bleeding and quicker incision time, concerns about wound infection, delayed healing, and scarring have limited its use for skin incisions.

Material and Methods

This study aims to compare the outcomes of diathermy versus scalpel incisions in terms of incision time, blood loss, postoperative pain, wound infection, and scar characteristics in inguinal surgeries. Conducted at Gulbarga Institute of Medical Sciences, Kalaburgi, this prospective randomised control study spanned from August 2023 to May 2024. A total of 81 patients were randomly assigned to either the scalpel incision group [n = 40] or the diathermy incision group [n = 41].

Results

The findings indicate that diathermy incisions offer significant benefits over scalpel incisions, including reduced incision time, lower blood loss, and decreased postoperative pain. The study utilised the Manchester Scar Score to assess wound characteristics, finding no significant difference between the two groups in terms of wound healing and scar quality. The safety and efficacy of electrocautery were further supported by the absence of significant differences in postoperative wound complications, hospital stay duration, and cosmetic outcomes between the two methods.

Conclusion

In conclusion, diathermy presents a safe and effective alternative to scalpel incisions, offering reduced intraoperative blood loss and postoperative pain without compromising wound healing or increasing complications. However, the choice between diathermy and scalpel should consider the surgeon’s expertise and the specific surgical context. While diathermy shows clear advantages, certain scenarios may still necessitate the use of a scalpel. Thus, the optimal surgical approach should be determined through careful evaluation of each individual case.

Published: February 2025

The treatment of patients with prostatic diseases is dependent upon the type and nature of the disease. The open prostatectomy for benign prostatic hyperplasia (BPH) is still relatively common in low- and middle-income countries despite one of its dreadful haemorrhagic complications and the attendant morbidity and mortality. This is a report of a 70-year-old retired farmer who was referred from a private health facility after open transvesical prostatectomy for an initial diagnosis thought to be BPH. He developed haemorrhagic complications with retained organised blood clot and gossypiboma warranting resuscitation, re-exploration, and removal with subsequent histological confirmation of prostate cancer. The patient, however, succumbed to the second haemorrhagic episode. Haemorrhage is a dreaded complication of open transvesical prostatectomy and a key cause of morbidity and mortality. Proper patient evaluation and selection for open prostatectomy can avert possible disaster.

Introduction. Effective personnel management has a direct impact on business continuity and enterprise value. Hence, it becomes a powerful tool in implementing a strategy and mission for small and large companies. The major target of strategic personnel management is the increase of personnel involvement that results in productivity development and company efficiency increase. Thus, a company with high involvement of personnel shows 40 lower staff turnover, employees in this company surpass expectations 10 more often, and a 5year revenue growth is 2,5 times higher in comparison with the company with low personnel involvement. The goal of the research is to assess the level of personnel involvement as one of the tools for the strategy of effective personnel management. Results: 1) the representation of the notion of personnel involvement and factors influencing the level of personnel involvement were systematized 2) a comparative characteristics of the level of personnel involvement on a countrybycountry basis was offered 3) an analysis of the level of personnel involvement in Chelyabinsk companies (survey) was carried out 3) the course for improvement of personnel involvement as an important tool for the strategy of effective personnel management was offered. Results interpretation and analysis. The study made it possible to systematize the representation of the notion of personnel involvement and to determine the major factors having the influence on its level. The highest level of personnel management in the world is observed in the United States of America (33), in Great Britain it is 17, in China 6, in Russia 19. This is a mean value. The study taken by Gallup Q12 showed that the level of personnel involvement was 69 (Five hundred employees of different categories in Chelyabinsk companies took part in the research). Employees do not consider themselves to be affiliated with their company and do not feel themselves as a part of the same whole to a greater extent. Conclusion. The authors offer to hold project sessions in order to solve the problems together, distribute functions, develop professional and personal qualities of employees. It will make it possible to establish trustbased relations between business owners and employees, and to raise the feeling of affiliation with the company.

Introduction. Paper is addressed to the service life tests of medical exoskeleton for children. There is briefly discussed the method and telemetry of tests. Besides, energy costs of the exoskeleton and a person for straight walking case were obtained. Exoskeleton with a weight dummy similar in mass and dimensional characteristics to a man was mounted on a medical treadmill (conveyor belt with an adjustable drive). Exoskeleton drives were programmed with the laws of motion similar to locomotion of a straight walking man. Sensors allowed to gather data on the operation of the directcurrent motors in the exoskeleton drives at a steadystate motion. The current loads of the drives were read by the shunting method. Findings. The paper presents generalized data from sensors, telemetry data, graphs of currents and angular values observed in hinges. Successful life tests showed that, in general, the exoskeleton meets the requirements of the technical specification. After carrying out tests, we performed a comparison of the energy costs that are spent for straight walk of a person and exoskeleton. According to the fact that the kinematics of a straight walking person and exoskeleton are similar, the power (moment) loads in the drives and joints turned out to be similar. In the exoskeleton, the moment load in the drive is proportional to the electric current at the motor clips. Comparison of the load in one step cycle yielded graphs that almost satisfy the data on the change in moments in the knees and hip joints of a man according to D. Winter. It has been taken into account that an exoskeleton with a more rigid structure exhibits rougher motions when stepping. It leads to the striking reaction that gives rise to oscillating motion and vibrations. The effect influences power (moment) characteristic of walking. Practical significance. The outcomes of the analysis could be applied for developing methods of myostimulation of the muscles of the patient legs, because it is directly related to the occurrence of a moment in the joints of a man.

Introduction. Applying ultraviolet radiation is topical for solving scientific and practical problems. A lot of application fields that involve detection of ultraviolet radiation requires the expansion of the list of relevant materials and the development of new technologies for producing ultraviolet sensors. ZnO thin films are widely used in detecting and measuring tools for the ultraviolet range due to a wide UV gap band (3.37 eV) and unique optical characteristics. The aim of the research was the development of technology of producing UV photodielectric sensitive element based on ZnO thin films. To achieve the aim, the following problems were posed and solved: 1) obtain an experimental sample of the UV photodielectric sensitive element 2) study the photodielectric effect in zinc oxide films obtained by reactive magnetron sputtering 3) determine the optimal voltage and frequency of the measuring signal for the adequate operation of the UV photodielectric sensitive element. Findings: 1) Technology of producing sensitive element based on the photodielectric effect was developed. The sensitive element has an integrated sensitivity of 2 pF/lm to the wavelength range of 200-400 nm. Element exhibits the highest sensitivity of 2.2 pF/lm to monochromatic radiation with a wavelength of 372 nm 2) It was experimentally proved that the zinc oxide thin films, obtained by magnetron sputtering, exhibit a change in dielectric constant in the range of 3.683 due to exposure to ultraviolet radiation in the wavelength range of 200400 nm 3) The measurement results showed that the measuring signal with a voltage of 1 V and a frequency of 500 kHz is optimal for the operation of the photodielectric sensitive element.

Introduction. Currently, the research into the possibility of spreading signal bandwidth over the channel coherence bandwidth by compensating the channel influence to increase the coherence bandwidth is actively carried out. Previous studies showed that for frequency hopping signals it is crucial to study the effect of phase jitter the signal elements due to phase dispersion in the HF radio channel. Thus, theoretical and experimental studies of phase dispersion are topical. The aim of the research was the development and study of a method of measuring the phase-frequency response of a wideband ionospheric channel in the presence of frequency dispersion with the use of a SDR ionosonde and an international IRI model. Findings. Paper presents the novel method for experimental measuring phase-frequency response (PFR) of a wideband ionospheric channel. PFR were measured in full-scale experiments with the use of the SDR ionosonde and the IRI model. They allowed to estimate the broadening (group delay dispersion) of the wideband channel impulse response due to dispersion, as well as the maximum value of the phase jitter when using wideband pseudo-random frequency hopping. We proposed a new approach for estimating the error in measuring phase. Experimental values of errors were obtained. An experimental verification of the outcomes of theoretical studies was carried out on the Cyprus-to-Yoshkar-Ola path with the use of the SDR ionosonde developed in Volga State University of Technology and the IRI model. Conclusion. The obtained theoretical and experimental data proved the feasibility of a significant expansion of a communication signal bandwidth even in conditions of a varying propagation medium, which is the Earths ionosphere.

Introduction. Technical upgrade of the industry is mainly focused on the integration of state-of-the-art automatic control systems based on single modules that combine electromechanical components controlled by microprocessors, personal computers or other facilities. One of the promising methods for improving controlled electrical drives is an engineering modification of an electrical machine by implementing two or more rotors, while the internal rotor is a regular one, the external rotor is made in the form of a hollow cylinder, the stator is of a traditional design. The development of the control systems for such machines based on microprocessor technology is topical. The aim of the research was the development of the microprocessor closed loop system for controlling an electrical drive and an experimental study into the influence of external factors on the state of the object, ensuring the regulation of the output shaft speed in a wide range. Findings. Analyzing the typical structures of controlled electrical drives, we came up with design of a double-rotor electrical machine with differential control, where the inner and outer rotors rotate in opposite directions relative to each other. When operated, the power is distributed between the two rotors, and the excess of mechanical power, which is not currently required, is transformed into electrical power. The proposed electrical machine exhibits improved mechanical characteristics, has a wider field of application and can operate in the energy-saving power mode. It was found that the output parameters of the electrical drive can be controlled by changing the load moment on the external rotor of differential type drive. Conclusions. An analysis of the results showed that the integration of a closed loop control system into the electrical drive based on a two-rotor electric machine with differential control provides an efficient distribution of the rotational speeds of the main and additional rotors.

Сконструированы вейвлеты с прямоугольной амплитудно-частотной характеристикой, которые нельзя получить во временной области из-за явления Гиббса.

Introduction. The paper proposes algorithms for calculating forward and inverse continuous WT in the frequency domain, which can be used for the decomposition and reconstruction of signals with high speed and accuracy. Also, ways to improve algorithms to further increase the speed of calculating the WT are proposed. The relevance of the problem under study is due to the fact that continuous WT allows for multi-scale analysis of signals with a multiplicity of less than two. Also, the construction of symmetric and antisymmetric orthogonal wavelets in the frequency domain with the maximum possible number of zero moments makes it possible to analyze a more subtle (high-frequency) structure of the signal, suppressing its slowly changing components, which makes it possible to concentrate energy in a few significant coefficients, which is a prerequisite for compression. Such wavelets make it possible to reduce the time of continuous wavelet transformation by several orders of magnitude compared to direct numerical integration. The aim of the research is an increase in the accuracy of decomposition and reconstruction of one-dimensional and two-dimensional signals, with a decrease in the calculation time in the implemented algorithms. Research methods. To increase the speed, the authors have developed algorithms for forward and inverse continuous fast WT in the frequency domain using the fast Fourier transform (FFT). Research finding and discussion. The calculation time of forward and inverse WT signals in the frequency domain was compared with the calculation time of forward and inverse WT by direct numerical integration. A new wavelet is proposed that allows a 1,000,000-fold increase in the speed of the inverse WT compared to direct numerical integration. Conclusions. Wavelets or digital filters obtained in the frequency domain have an ideal frequency response within the calculation error and allow very accurate signal reconstruction. Wavelets with rectangular frequency response made it possible to reduce the calculation time of direct WT in the frequency domain by 2 times compared to when wavelets based on derivatives of the Gaussian function were used. And the calculation time of the reverse WT signal with a sample size of 32768 and 262144 samples decreased by 260 and 5000 times, respectively, compared to the algorithm using the FFT.

ABSTRAK Return saham dapat dipengaruhi oleh sejumlah faktor baik internal maupun eksternal. Dari beberapa faktor yang mempengaruhi return saham, profitabilitas dan Economic Value Added - sebuah pendekatan baru dalam menilai perusahaan - dianggap sebagai dua faktor penting yang dapat menjelaskan perilaku return saham di pasar modal. Tujuan utama dari penelitian ini adalah untuk menguji dua faktor (EVA, ROA) dan satu variabel kontrol (return saham sebelumnya) terhadap return saham perusahaan manufaktur yang terdaftar di Bursa Efek Jakarta. Penelitian ini menggunakan data panel dengan pengamatan total 32 data perusahaan untuk periode tahun 2007-2010. Sampel dipilih dari populasi perusahaan manufaktur milik indeks LQ45 menggunakan teknik purposive sampling. Regresi Linier Berganda digunakan untuk menganalisis data. Hasil penelitian menunjukkan bahwa EVA dan ROA berpengaruh secara simultan terhadap return saham. Namun, analisis parsial menunjukkan bahwa kedua variabel tidak mempengaruhi return saham secara signifikan, tetapi hanya variabel return saham sebelumnya. Koefisien regresi R Square sebesar 0,252. Ini berarti bahwa variasi variabel independen, yaitu EVA dan ROA, dapat menjelaskan 25,2% dari variabel dependen, sedangkan sisanya 74,8% dijelaskan oleh variabel independen lainnya yang tidak dimasukkan dalam model analisis. Kata kunci : Economic Value Added, Return On Assets, dan Return Saham.
