OBJECTIVE

The aim of this study was to evaluate the effect of standardized care guidelines featuring next-day discharge on hospital length of stay (LOS), outcomes, patient experience, and healthcare consumption in patients receiving ventriculoperitoneal shunts (VPSs) for idiopathic normal pressure hydrocephalus (iNPH).

METHODS

This single-center population-based observational cohort study included 271 adult iNPH patients who underwent VPS surgery at Karolinska University Hospital. Groups were compared before and after the implementation of new standardized discharge guidelines. The primary outcome was the hospital LOS. Secondary outcomes included postoperative complications, patient experience, and frequency of unscheduled outpatient follow-up appointments.

RESULTS

A total of 121 patients were treated with variable hospitalization periods. One hundred fifty patients were managed under the new guidelines stipulating next-day discharge. There was no significant difference in positive surgical outcome (66% vs 71%, p = 0.372) or rates of complication (p ≥ 0.066) between groups. The standardized guidelines group had a significantly shorter period of inpatient hospitalization (1 vs 2 days, p < 0.001) and demonstrated lower levels of unscheduled outpatient healthcare consumption (p < 0.001) while maintaining levels of positive patient experience (p = 0.828).

CONCLUSIONS

Standardized discharge guidelines featuring next-day discharge are safe for iNPH patients undergoing VPS surgery, maintain the quality of the patient experience, and are an effective method for mitigating healthcare consumption in an expanding patient group.

OBJECTIVE

This study aimed to retrospectively evaluate the efficacy of stereotactic body radiotherapy (SBRT) for pain relief in patients with painful spinal bone metastases (SBMs) and to identify key factors contributing to treatment outcomes.

METHODS

The authors conducted a retrospective analysis of adult patients who underwent SBRT for painful solid tumor SBMs between March 2012 and January 2023. During this period, SBRT was performed adhering to the International Spine Radiosurgery Consortium guidelines and international consensus recommendations for target volume delineation. To be included, patients needed to experience persistent pain directly associated with SBMs, warranting regular opioid treatment. Positive pain relief post-SBRT was defined by three criteria: 1) a decrease in the severity of pain; 2) reduction in opioid dosage; and 3) concurrent improvement in daily activities. The revised Tokuhashi score and Spine Instability Neoplastic Score were used to identify crucial factors influencing treatment outcomes.

RESULTS

This study included 377 patients, covering 576 lesions across 759 vertebrae. Of these, 332 lesions showed significant pain relief within 3 months following SBRT. Lower pain relief rates were observed in patients with a revised Tokuhashi score of 0–8 or in patients with diabetes mellitus. In contrast, higher relief rates were linked to treating a single painful SBM in 1 SBRT course, and greater contouring of the involved sectors according to International Spine Radiosurgery Consortium guidelines and international consensus recommendations. The highest pain relief rate was observed in patients with prostate cancer (73.8%), whereas the lowest rate was observed in patients with hepatocellular carcinoma (36.4%). The presence of pre-SBRT vertebral fractures, the dosage and fraction of SBRT, and the use of concurrent systemic cancer therapies or antiresorptive agents, including bisphosphonates and denosumab, did not notably influence the pain relief efficacy of SBRT. Comprehensive medical records 6 months after SBRT treatment were available for only 362 lesions. The overall rate of pain relief observed was 32.6%.

CONCLUSIONS

SBRT is an effective treatment approach for managing painful SBMs, achieving a pain relief rate of 57.6% within 3 months and maintaining a rate of 32.6% at 6 months after treatment. The transition to osteoblastic lesions may potentially improve the stability of SBMs, indicated by lower Spine Instability Neoplastic Score, which in turn could extend pain relief management.

Published: August 2024

Regular watering is a very important activity in plant maintenance because plants need water to carry out photosynthesis and obtain the nutrients necessary to grow and develop properly. An automatic watering tool has been designed that can perform watering commands remotely. This automatic watering instrument is achieved by using a soil moisture sensor to measure the water content or soil moisture and a DHT22 sensor that can detect air temperature and humidity. Soil moisture information is sent via Telegram, using the Telegram bot feature on this automatic plant watering tool, so that the tool can be controlled remotely. This plant monitoring can save time and energy and maintain plant quality more effectively. Plant conditions can also be checked periodically to ensure that the plant's water needs are being properly met. This automatic plant watering solution therefore has the potential to increase productivity and efficiency in case of irregular watering of the plants.

Published: August 2024

The airport is a strategic place where it involves important activities, namely airplane flights. Airport activities are greatly influenced by the ongoing security within the airport. The thing that affects security in the airport is the possibility of crimes committed by unexpected visitors. The purpose of this research is to observe the airport area, especially airport visitors so that if there are visitors who have the potential to commit crimes, they can be detected properly and further investigation procedures can be carried out.  To be able to observe airport visitors and recognize patterns of visitor behavior that have the potential to commit crimes, an airport visitor gesture recognition system can be used. In this thesis, the gesture recognition of airport visitors is done with the multipose estimation method. This method can detect 17 key points on the human body that are used to detect the behavior of airport visitors who have the potential to commit crimes. To develop this system, deep learning algorithms that are currently developing with the help of TensorFlow and architectural models in multipose estimation, namely MobileNetV2, Feature Pyramid Network, and CenterNet, can be used. The experimental results show that the multipose estimation method can recognize human gestures well under several conditions such as the appropriate distance of the human object from the camera and the lighting conditions around the observed human object. It is also seen that from several scenarios, the crime gesture model can be recognized well.

Published: August 2024

Melons are one of the fruit types widely favored in the market due to their high content of vitamins, minerals, and water. Melon plants are challenging to cultivate when environmental conditions such as soil and air do not align with their characteristics. One way to address this is through hydroponic cultivation, which reduces the interaction of melon fruits with the air and environment. However, this method has a drawback in that the nutrient solution and water circulation of the plants must be continuously monitored. Therefore, a system is needed to automatically monitor and control the conditions of hydroponic plant growth with the assistance of IoT technology. This research proposes the Design and Implementation of a Monitoring and Automation System for Hydroponic Plant Control Based on the Internet of Things. The hydroponic system, specially designed for melon plants, is equipped with various sensors that can monitor soil nutrients in real time through mobile devices. Based on the test results, the TDS sensor yielded a result of 1313 PPM, the pH Water sensor showed 50.1, and the system also measured air temperature and humidity using DHT22, with air temperature at 29.5°C and humidity at 71.2%.

Минеи четьи Германа Тулупова остаются на данный момент малоисследованным литературным памятником Древней Руси. Целью настоящей работы стало выявление разночтения текстов сказаний, посвящённых Владимирской иконе Божией Матери в минеях четьих Германа Тулупова и в минеях четьих «Живоначальные Троицы Сергиева монастыря, иже въ Маковце Радонежском». В процессе работы выявлено существенное различие текстов трёх сказаний посвящённых Владимирской иконе Божией Матери в минеи четьей Германа Тулупова (август) и в минеи четьей (август) «Живоначальные Троицы Сергиева монастыря, иже въ Маковце Радонежском». Согласно прежним научным исследованиям, принято было считать, что минеи четьи «Живоначальные Троицы Сергиева монастыря, иже въ Маковце Радонежском» списаны с миней четьих Германа Тулупова, однако данное исследование позволяет внести корректировки в это представление.

The Menaias of the reading of German Tulupov remain at the moment a little-studied literary monument of Ancient Rus’. The purpose of this work was to identify discrepancies in the texts of the legends dedicated to the Vladimir Icon of the Mother of God in the menaias of the readings of German Tulupov and in the menaias of the readings “The Life-Giving Trinity of the Sergius Monastery, ilk in Makovets of Radonezh”. In the course of the work, a significant difference was revealed in the texts of the three legends dedicated to Theotokos of Vladimir in Menaion Readers by German Tulupov and the text of the legends about Theotokos of Vladimir in Menaion Reader of august “The Life-Giving Trinity of the Sergius Monastery, located at Makovets of Radonezh”. According to the previous studies, it was generally accepted that Menaion Readers of “The Life-Giving Trinity of the Sergius Monastery, located at Makovets of Radonezh” were written off from the Mienaion Reader of august by German Tulupov, however, this study allows us to make adjustments to this idea.

В настоящей статье автор выявляет специфику образов духовенства в творчестве Н. С. Лескова. С этой целью описывается положение священнослужителей в дореволюционный период, анализируется интерес к духовенству в беллетристике второй половины XIX в., даётся типология образов священнослужителей в некоторых произведениях русского писателя. Важным является соотнесение образов духовенства в творчестве Н. С. Лескова с теми литературными типажами, которые были распространены в литературе XIX в. Данное исследование позволяет уточнить некоторые аспекты соотношения Православия и русской литературы, глубже понять религиозность Н. С. Лескова, а также соотнести церковную жизнь дореволюционного периода с реалиями современной жизни. Автор сделал вывод о том, что описание духовенства в творчестве Н. С. Лескова обладало существенной новизной для литературы своего времени. Образы священнослужителей в произведениях русского писателя можно разделить на два типа: любящие ближнего и исполнители обряда. Любовь священнослужителя к людям делает простительными несовершенства его характера. Главным принципом в описании духовенства в творчестве Н. С. Лескова является примат личности.

In this article, the author reveals the specifics of the images of the clergy in the works of N. S. Leskov. For this purpose, the position of the clergy in the pre-revolutionary period is described, the interest in the clergy in the Belles-lettres of the second half of the 19th century is analyzed, and the typology of the images of the clergy in some of the works of the Russian writer is given. It is important to correlate the images of the clergy in the works of N. S. Leskov with those literary types that were common in the literature of the 19th century. This study allows us to clarify some aspects of the relationship between Orthodoxy and Russian literature, to better understand the religiosity of N. S. Leskov, as well as to correlate the church life of the pre-revolutionary period with the realities of modern life. The author concluded that the description of the clergy in the works of N. S. Leskov had a significant novelty for the literature of his time. The images of priests in the works of the Russian writer can be divided into two types: those who love their neighbor and those who perform the rite. The love of a clergyman for people makes forgivable the imperfections of his character. The main principle in the description of the clergy in the works of N. S. Leskov is the primacy of personality.

Published: August 2024

In the current era of globalization and the development of information technology, literacy skills have become critical skills that every student must master to face the challenges of the times. Literacy skills are related to reading, writing, and thinking activities that focus on increasing the ability to critically, creatively, and innovatively understand information. By reading, students will apply speaking and writing skills. Based on the results of interviews at one school, teachers have not made maximum use of interesting learning media. Therefore, it is necessary to create exciting learning media for reading skills. One of them is picture storybook media. Picture storybook media are suitable learning media to develop because engaging learning media can be used as teaching aids to illustrate material explained in related subject books. This research aims to produce picture storybooks based on the CRT approach to improve students’ reading literacy in lower grades. This research method uses the ADDIE model. Data collection uses scales, interviews, observations, and questionnaires. Data analysis techniques use descriptive analysis t-tests. In validating media, material, language, learning, and evaluation, the v-aiken results were 0.88, 0.85, 0.88, 88.3, ​​and 65, respectively, with decent classification. Then the t-test obtained a significance result 0.000, which means 0.000 < 0.05. In short, developing picture storybooks based on the CRT approach has increased students’ reading literacy in lower grades.

Lithogeochemical characteristics and sedimentary environments of the Uk Formation limestones (upper Riphean, Southern Urals)
Authors: Maslov A. V. , Dub S. A.
Published: August 2024

The lithogeochemical characteristics of the Uk Formation limestones (Uppermost Unit of the Riphean stratotype section in the Southern Urals) are considered. Data points of limestones (40 samples) accumulated in the middle and inner ramp environments have a quite contrasting distribution on diagrams with parameters (La/Sm)sh, (La/Yb)sh and (Sm/Yb)sh, proposed based on the systematization of a significant amount of analytical data on carbonate sequences formed in various platetectonic (in the broad sense of the word, paleogeographic) environments (according to [Zhang et al., 2017]) was established. The data points of the limestones of the Medved Member of the Uk Formation, which was formed, according to a detailed lithological-facies analysis, in the middle ramp environment, in the indicated diagrams located towards the field of limestones of the open ocean, while the limestones of the Manaysu Member (inner ramp deposits) in their geochemical characteristics are more consistent with the limestones of the near-coastal environments. Thus, the geochemical characteristics of the Uk Formation limestones seem to confirm the conclusions of the previous reconstructions. It has been suggested that in the example we described, the distribution of trace elements in the inner ramp limestones was apparently controlled by fine-grained siliciclastic material coming from the continent, while in the geochemical features of deeper-sea middle ramp limestones the influence of the open ocean environment is already perceptible.
A method for estimating of integral roundness index for a detrital zircons set: a case of the sequences from the Cimmerides of the Mountainous Crimea
Authors: Romanyuk T. V. , Kotler P. D.
Published: August 2024

A technique that allows to evaluate the degree of roundness of detrital zircon grains on a five-point scale according to the degree of preservation of the vertices, edges and faces of the crystals is presented. Based on the results of the degree of roundness of individual grains, the integral index SOs is calculated for a sample from various stratigraphic units. The obtained data makes it possible to determine the proportion of grains of different classes in different strata, to assess the degree of similarity/difference of samples, which can be an additional criterion when dividing sedimentary sections. The proposed method is used to compare the roundness characteristics of detrital zircons from a number of sedimentary sequences of the Cimmerides of the Crimean Mountains. It is shown that the sandstones of the Chenka sequence, relative to the sandstones of the flysch sequences, are characterized by a higher proportion of unrounded and weakly rounded zircon grains and a virtual absence of completely rounded grains. The values of the integral roundness index SOs for zircons from sandstones of the Tauride Groupe have showed values of 3.41 and 3.95, and for the Chenka sequence – 2.55. Thus, a significant difference in SOs was recorded between the studied strata, which is also confirmed by the values of the mutual pair coefficients p, calculated using the Kolmogorov–Smirnov test.

The results of experimental studies of the effect of residual magnetization on the corrosion of steel samples in an aqueous medium are presented. Algorithms of research and processing of results are described. Three cases of initial magnetization of samples are considered. It is established that before the critical magnetization of steel samples, the corrosion wear in the aqueous medium decreases, and then begins to grow. The discovered effect is of great theoretical importance in studying the phenomenon of corrosion, taking into account the initial residual magnetization, as well as of great practical importance, in particular, in the design and operation of various structures and structures made of steel to protect them from corrosion destruction.
A dynamic model and a new approach to analyzing the success of the soft landing process of a spacecraft with a mechanical landing device
Authors: Bakulin V. N. , Borzykh S. V.
Published: August 2024

An approach is proposed to analyze one of the most critical stages of spacecraft operation – the soft landing process, starting from the moment of the first contact of the spacecraft with the ground to its complete stop. It is noted that it is necessary to extinguish the significant kinetic energy that the device possesses at the moment of contact with the surface. The most common type of landing device is considered spring-lever type, including several supports with deformable energy absorbers. Limited opportunities for ground-based experimental testing of the soft landing process lead to the need to use a dynamic model to analyze the success of landing and rational selection of the characteristics of the landing device. The model of the landing process is based on the representation of the vehicle body and its landing device elements as a structurally complex mechanical system of bodies with internal connections, the type of which is determined by restrictions imposed on the relative movement of the system bodies. An approach to the for-mulation of special equations for determining bond reactions that reflects these limitations is presented. The success criteria of the landing process are described. The success analysis of the planting process is illustrated by a specific example.
Self-oscillating mode in an anomalous thermoviscous liquid flow
Authors: Kireev V. N. , Mukhutdinova A. A. , Urmancheev S. F.
Published: August 2024

It is known that the flow of liquids with a nonmonotonic dependence of viscosity on temperature (abnormally thermoviscous liquids) in the presence of temperature gradients, for example, when a heated liquid flows into a cooled channel, is accompanied by the formation of a high-viscosity region localized in the flow, which determines the features of its flow. In this paper, the conditions for the occurrence of self-oscillating regimes of flow rate variation during the flow of anomalously thermoviscous liquids in annular channels under the action of a constant pressure drop and under given conditions of heat transfer on the inner and outer walls of the annular channel are determined. It has been found that self-oscillations in the flow rate of an anomalously thermoviscous liquid can occur when flowing in an annular channel, on the walls of which there is an abrupt decrease in the intensity of heat transfer. The region of existence of the self-oscillation mode is determined by the values of the pressure drop and the geometric parameter equal to the ratio of the width of the annular gap to the radius of the inner cylinder. In addition, weakly damped flow rate oscillations with a very small damping decrement were also observed at the boundaries of this region.
Una reflexión filosófica de Gadamer sobre el olvido y el acontecer del lenguaje

The last one were used as a comparison group. Histological sections prepared according to standard methods for inspection microscopy were stained with hematoxylin and eosin. To study revascularization processes, an immunohistochemical reaction with CD-34 antibodies was performed. As a result of the study, it was established that in animals with a simulated complete transverse diaphyseal fracture of the femur and intramedullary fixation with implants made of carbon-carbon composite material in the bone regenerate, the relative area of ​​CD-34+ vascular endothelial cells probably increases compared to the group of animals in which fixation was performed using medical stainless steel. Thus, the use of carbon-carbon composite material reveals an angiogenic effect in bone regeneration, which accelerates the rate of repair and remodeling of fractures.

The purpose of this study is to investigate the impact that ROA, CR, TATO, and DER have on the stock prices of oil and gas companies that are listed on the IDX between the years 2015 and 2022. In 2022, the stock prices of eleven oil and gas businesses that were included on the IDX fell. Those who suffered the most were Akra and Apexindo Pratama Duta. In spite of the fact that AKRA's ROA increase from 4.83% to 9.12% in 2021–2022, the company's shares fell. Between the years 2015 and 2022, the prices of petroleum and natural gas stocks on the IDX were impacted by carbon reduction (CR), taxation (TATO), and demand-to-recovery (DTR strategies). Some researchers, including Kasmir and Sumarsan, discovered that ROA increases stock prices whereas DER decreases them. There is a comparison made between mining stock prices, ROA, ROE, NPM, and DER. The abstract of the Indonesian oil and gas stock price demonstrates how the success of a company's finances influences market prices. A non-random selection of six organizations was made for the study based on certain criteria. Balance sheets, income statements, equity statements, and cash flow statements that have been audited are evaluated using descriptive and verification statistical analysis. It would appear that the ROA T-statistic of X1 does not have any effect whatsoever on the values of stocks. When it comes to the most important T-statistic, the value 422 is lower than the confidence level of 95%. X2 represents the current ratio, X3 represents the total asset turnover, and X4 represents the debt to equity ratio. All three of these ratios are related to stock values. This is due to the fact that their T-statistics are increased in comparison to the primary T-statistic.
