Authors: Purnamasari Eka Rokhmiati Wahyu , Afrina Rina , Rizal Ahmad , Novianti Nadira , Ervina
Published: December 2024

Background: Patient safety is a critical focus in Indonesia, particularly in medication administration, where adherence to the “seven rights”—the right patient, drug, dose, route, time, documentation, and information—is essential. Despite established protocols, medication errors remain a challenge, highlighting the need for improved adherence among nurses, who are key players in ensuring safety.
Objective: This study aimed to assess nurses' adherence to the “seven rights” of medication administration and explore its relationship with nurse characteristics such as age, education, and career level at Bogor Hospital, Indonesia.
Methods: A cross-sectional descriptive study was conducted in May 2024 with 35 nurses selected via purposive sampling. Data were collected through non-disclosed observations using a questionnaire of “seven rights of medication administration” based on Bogor Hospital’s Standard Operating Procedures. Adherence was evaluated using the Gudman scale. Statistical analyses included descriptive and bivariate (chi-square) tests using SPSS version 23.
Results: The majority (57.1%) of nurses partially adhered to the “seven rights,” 25.7% fully adhered, and 17.1% did not adhere. All nurses consistently performed key practices such as patient identity verification and medication checking (100%). However, only 57% provided patient education. Career level significantly influenced adherence (p = 0.009), with higher-level nurses showing better adherence. Age, gender, and education level showed no significant correlation.
Conclusion: While adherence to core protocols was high, gaps in patient education highlight areas for improvement. Targeted training and educational advancements, especially for entry-level nurses, are essential to enhance patient safety and medication administration practices. However, further studies are needed to validate the findings.

Authors: Matumadi Iman U. , Caorong Laarni A. , Bangcola Ashley A.
Published: December 2024

Background: The transition to motherhood is a significant life event that can be both exciting and challenging, often complicated by postpartum depression. Understanding the awareness, risk factors, and support systems related to postpartum depression is crucial for improving the quality of life among new mothers.
Objective: This study aimed to explore the quality of life, awareness of postpartum depression, level of depression, and perception of support among primipara postpartum mothers in selected Rural Health Units (RHUs) of Lanao del Sur, southern Philippines, while also examining the correlation between awareness of postpartum depression, perception of support, and quality of life.
Methods: A descriptive-predictive study design was employed. A stratified random sampling method was used to select 356 respondents from a population of 4,694. Data were collected using questionnaires, including a self-developed survey for postpartum depression awareness and perceived social support, the Edinburgh Postnatal Depression Scale for depression levels, and the WHOQOL-BREF for assessing quality of life. Descriptive statistics and regression analysis were applied to interpret the data.
Results: The majority of respondents were young, married women with diverse educational and income backgrounds. Moderate awareness of postpartum depression was noted, with many respondents reporting mild depression. Strong support systems involving family, friends, healthcare providers, and peer groups were identified as essential in managing postpartum depression. Regression analysis indicated that awareness of postpartum depression (β = 0.400, p <0.001) positively influenced quality of life, whereas higher risk for postpartum depression (β = -0.229, p <0.001) was associated with reduced quality of life.
Conclusion: These findings emphasize the need to enhance awareness and support systems to effectively manage postpartum depression, thereby improving the quality of life of postpartum mothers at risk. Improving health information dissemination and healthcare services is critical for addressing postpartum depression in rural settings.

Published: December 2024

This study aims to determine the relationship between online sports consumption motives and points of attachment among professional football team fans. The study's population consists of professional football team fans in Turkey. A total of 226 football fans—50 women and 176 men—selected by purposive sampling participated in the study. The study used a survey form consisting of the Points of Attachment Index (PAI), the Motivation Scale for Sport Online Consumption (MSSOC), and demographic questions as data collection tools. We collected and analyzed the research data face-to-face using the SPSS 23.0 package program. In addition to descriptive statistics, independent samples t-test, one-way ANOVA, and Pearson correlation analyses were applied to evaluate the data. The analysis of the fans' attachment points to their teams revealed that the "team" sub-dimension had the highest average, as per the research findings. Conversely, the analysis revealed statistically significant differences in the sub-dimensions of points of attachment based on gender, age, and frequency of web participation variables. We determined that among the motives for online sports consumption, the "team support" sub-dimension had the highest mean. These motives had statistically significant differences according to gender, educational status, marital status, and web participation frequency variables. Finally, our study determined a low negative relationship between the points of attachment and the online sports consumption motives of football fans.

Владимир Иванович Даль – первооткрыватель народной культуры в эпоху Николая I
Authors: Даренская Вера Николаевна
Published: December 2024

В статье рассмотрено наследие В. И. Даля, касающееся исследований русской народной культуры и мировоззрения, начатых им в эпоху Николая I. Показано, что идеи Даля позволяют более четко исследовать основные компоненты традиционного народного мировоззрении. Концепция Даля также имеет прогностическое значение до настоящего времени, поскольку в ней сформулированы принципы усвоения народом новых культурных явлений. Игнорирование этих принципов в бездумной погоне за внешним «прогрессом» привело к катастрофам ХХ в., поскольку разрушило традиционный уклад жизни народа и его нравственные основания. Концептуализация В. И. Далем мировоззрения русского народа является важной частью истории русской гуманитарной науки и требует развития в наше время.

Published: December 2024

One of the most important forms of reporting for organizations
(including healthcare organizations) is the financial performance
report. A new federal accounting standard, FSBU 4/2023 “Accounting
(Financial) Statements”, has recently been adopted. According to it, starting
with the 2025 reporting, the financial performance report will be prepared
according to new rules. The article examines the new approaches
of FSBU 4/2023 “Accounting (Financial) Statements” to the formation of
the financial performance report. At the same time, the degree of similarity
between the rules of FSBU 4/2023 “Accounting (Financial) Statements”
and the recommendations that were presented in the draft FSBU
4/2023 “Accounting (Financial) Statements” is analyzed. The article
compares the composition and structure of the financial performance
report in FSBU 4/2023 “Accounting (Financial) Statements”, the draft
FSBU 4/2023 “Accounting (Financial) Statements” and the currently valid
PBU 4/99 “Accounting Statements of an Organization” and the Order of
the Ministry of Finance of Russia No. 66n of July 2, 2010 “On the Forms of
Financial Statements of Organizations”. Both appropriate innovations of
FSBU 4/2023 “Accounting (Financial) Statements” in relation to the formation
of the financial performance report and existing controversial
aspects are identified. Recommendations for resolving controversial
aspects of the formation of the financial performance report in the process
of further development of accounting are substantiated.

Published: December 2024

Chronic kidney disease (CKD) has been identified as a serious public health issue. Patients with end-stage renal disease undergoing hemodialysis (HD) report a significant decline in life satisfaction, particularly due to physical fatigue, social limitations, and psychosocial problems. According to the Centers for Disease Control and Prevention (CDC) in 2021, CKD progresses slowly and affects more than 10% of the global population, equivalent to approximately 800 million individuals. This literature review aims to explore the coping experiences of patients undergoing hemodialysis. The sample criteria for articles were based on PICOS elements, specifically focusing on the coping mechanisms of hemodialysis patients. The databases used include PubMed, Science Direct, and Google Scholar, with keywords targeting the coping mechanisms of patients undergoing hemodialysis. A total of seven articles were retrieved. The search results underwent a screening process using PICO elements (Population/Patient/Problem, Intervention, Comparison, Outcome) and the CRAAP method (Currency, Relevance, Authority, Accuracy, Purpose), with inclusion criteria limited to adult patients. The findings identified eight main themes: physical activity, satisfaction with physical fitness during hemodialysis, perceptions of their condition during hemodialysis, sleep quality during therapy, personal adaptation to physical changes, social relationships, changes in economic status during therapy, and spiritual responses. In conclusion, spiritual and medical approaches, along with biological, psychological, social, and spiritual impacts, play crucial roles in shaping patients’ experiences. A deeper understanding of these themes can assist healthcare providers in designing more effective and holistic interventions to improve the quality of life for CKD patients undergoing hemodialysis.

Behavioral studies of incubating and chick-feeding passerines imply round-the-clock observations at the nest. Camera traps can replace the observer helping to collect a significant amount of data without much time and effort . But this method also has disadvantages. The motion sensor of the camera trap often delays to catch a bird flying out of the nest:according to our data, in 48.7 % of cases the camera trap missed to capture the flying out. Processing photo and video files requires a lot of cameral time. Difficulties arise already at the first stage when extracting metadata from media files. We managed to solve the latter problem by using the ExifTool command. Biologically significant data were processed manually using MS Excel. Comparison of two models of camera traps (Reconix PC90 and SEELOCK ABP) showed the advantage of the first model over the second. We identified the most optimal camera trap settings for the time budgets of the White wagtail Motacilla alba ocularis and the Snow bunting Plectrophenax nivalis, both in the incubation period and in the period of feeding chicks. In the incubation period, the use of a time-lapse (with an interval of 1 minute and 1 shot per session) and a motion sensor (2 shots per session) was optimal. In the period of chick-feeding, the motion sensor shooting with 3 shots per session and a delay of 15 seconds between sessions was found to suit the purpose.

Studies of mitochondrial DNA (mtDNA) polymorphism provide information about episodes of population genetic history at various time scales, from tens of thousands to several hundred years ago. To date, it has been established that the gene pools of the Siberia's indigenous peoples contain virtually no traces of the oldest Upper Paleolithic inhabitants. The present study demonstrates that one such relic is mitochondrial haplogroup A8b, which is distributed at a low frequency in certain contemporary indigenous populations of Priokhotye. These include the Itelmens and the Koryaks of Kamchatka, the Ainu of Hokkaido, and also representatives of the Okhotsk archaeological culture distributed in Hokkaido, in Sakhalin, and in the Kuril Islands. The phylogenetic analysis of complete mitochondrial genomes belonging to haplogroup A8 revealed that the divergence of A8b occurred in the Upper Paleolithic period, approximately 16-17 thousand yrs. B.P. It seems probable that A8b haplotypes were among the "Beringian" set of mtDNA lineages that have survived to the present days in the Priokhotye population. It is also assumed that haplogroup A8b carriers spread in the Sea of Okhotsk region from Kamchatka through the Kuril Islands to Hokkaido and Sakhalin in the last few millennia.

Authors: Erbaş Oğuzhan
Published: December 2024

Geothermal energy is a naturally renewable resource and can produce electricity and heat without harming the environment with less carbon dioxide emissions than fossil fuels. This makes it an environmentally friendly option. Our country is located on an active tectonic belt and has an important position in the world in terms of geothermal energy resources. For this reason, we have a high potential to benefit from geothermal resources. The design of the geothermal energy electricity generation system (turbine, heat exchanger, fluid properties, etc.) also plays a critical role in terms of efficiency. The system should be optimized according to conditions such as temperature and pressure. In this study, electricity production performances were compared for different fluid types in the secondary cycle, turbine efficiency and wellhead temperature in an energy conversion plant using a geothermal fluid with a source temperature of 195 0C.

Принцип двойственности в математической теории общего равновесия
Authors: Козырев А.Н.
Published: December 2024

В статье излагается подход к математической теории экономического равновесия на основе последовательного применения принципа двойственности, привнесенного Л.В. Канторовичем из функционального анализа в выпуклый анализ, в линейное программирование и в экономику. Показано, что, следуя принципу двойственности, можно переписать все элементы известных моделей экономического равновесия на языке сопряженных пространств, сопряженных конусов и сопряженных полиэдров. Это позволяет очистить математические конструкции, используемые в теории общего экономического равновесия, от шлейфа идеологических догм, придать им в отдельных случаях новую интерпретацию и эффективно использовать в реальной экономике.

The article describes an approach to the mathematical theory of economic equilibrium based on the consistent application of the duality principle introduced by L.V. Kantorovich from functional analysis to convex analysis, linear programming and economics. It is shown that, following the principle of duality, it is possible to rewrite all the elements of known models of economic equilibrium in the language of conjugate spaces, conjugate cones and conjugate polyhedra. This makes it possible to clear the mathematical constructions used in the theory of AER from the plume of ideological dogmas, to give them a new interpretation in some cases and to use them effectively in the real economy.
Технологический суверенитет и глобальная конкуренция
Authors: Белоусов Ф.А. , Иванова А.К. , Неволин И.В.
Published: December 2024

Экономическая модернизация и технологическое развитие страны всё больше связывают с мерами по укреплению международного сотрудничества и развитию возможностей взаимодействия в области высоких технологий. Если в 2015 г. развитие получили меры по усилению диалога между государством и бизнесом (деловые форумы с представителями органов власти, программы поддержки малого и среднего бизнеса, меры поддержки экспортеров), то сегодня на фоне ужесточения глобальной технологической конкуренции, роста протекционизма и феномена экстерриториальных экономических ограничений, внимание обращено на развитие международного технологического сотрудничества. Причём последнее приобретает не только стратегическую значимость, но, попадая в сферу экономической безопасности России, также получает иное наполнение в качестве объекта исследования. Новое понимание этого явления показал прошедший в сентябре 2024 года Международный технологический конгресс. Его центральной темой стало технологическое партнёрство и возможности для его развития между странами, в том числе, в рамках БРИКС. Отраслевые вопросы красной нитью связывала тема сотрудничества, надежного и долгосрочного партнёрства как основы технологического суверенитета. Данная статья вносит вклад в обсуждение темы технологического суверенитета, представляя позицию бизнеса в сообщениях участников конгресса. Эта позиция соотносится с возможными барьерами на пути к технологическому суверенитету и научными методами их преодоления. Подробного рассмотрения заслужили технологии искусственного интеллекта как одно из направлений сотрудничества и достижения в этой сфере, озвученные участниками конгресса.

Economic modernization and technological development are increasingly associated with measures to strengthen international cooperation. In 2015, measures were developed to strengthen the dialogue between the government and business. Nowadays, however, the intensification of global technological competition, the growth of protectionism and the phenomenon of extraterritorial economic restrictions move the focused on the international technological cooperation. The latter has strategic importance and receives a different content as an object of research. A new understanding of this phenomenon was shown by the International Technological Congress held in September 2024. Its central theme was technological partnership and opportunities for its development between countries, including BRICS platform. The theme of cooperation, reliable and long-term partnership as the basis of technological sovereignty threaded the industry issues. This article contributes to the discussion of the topic of technological sovereignty by presenting the position of business in the messages of the congress participants. This position correlates with possible barriers to technological sovereignty and scientific methods of overcoming them. Artificial intelligence deserves detailed consideration as one of the areas of cooperation, according to the participants of the congress.

В данной работе рассматривается задача многопериодного прогнозирования реализованной волатильности (realized volatility, ) и системного бэк-тестирования торговых стратегий для опционов на торгуемые биржевые фонды (Exchange-Traded Fund, ETF). Цель исследования – построение моделей глубокого обучения для многопериодного прогнозирования волатильности активов, таких как SPY и QQQ, и проверка эффективности прогнозов в рамках бэк-тестирования опционных стратегий. Для прогнозирования было использовано несколько архитектур нейронных сетей: LSTM, GRU, BiLSTM, BiGRU, FNN и NBEATSx, а также базовая эконометрическая модель HAR-RV для сравнения. В исследовании вводится новая функция потерь, квантильный лог-гиперболический косинус, для повышения точности прогнозов на высоких значениях волатильности. Точность моделей оценивалась на основе метрик MSE, MAE, MAPE и скорр. , что показало превосходство рекуррентных архитектур. С целью апробации в условиях различных рыночных сценариев полученные прогнозы реализованной волатильности были использованы в бек-тестировании двух опционных стратегий: стрэддл и v-скальпинг.

This paper considers the task of multi-period forecasting of realized volatility ( ) and systematic back-testing of trading strategies for options on traded exchange-Traded funds (Exchange-Traded Fund, ETF). The purpose of the study is to build deep learning models for multi–period forecasting of asset volatility, such as SPY and QQQ, and to verify the effectiveness of forecasts as part of back-testing of option strategies. Several neural network architectures were used for forecasting: LSTM, GRU, BiLSTM, BiGRU, FNN and NBEATSx, as well as the basic econometric model HAR-RV for comparison. The study introduces a new quantile log loss function, the hyperbolic cosine, to improve the accuracy of forecasts at high volatility values. The accuracy of the models was estimated based on the metrics MSE, MAE, MAPE and , which showed the superiority of recurrent architectures. In order to test the forecasts of realized volatility in various market scenarios, the obtained forecasts were used in the back-testing of two option strategies: straddle and v-scalping.

Сенсорная активность мозга является необходимым компонентом психических и физиологических процессов, связанных с восприятием информации и возникновением различных заболеваний, в том числе обусловленных нарушением периферических границ поля зрения, отслоением сетчатки глаза и других. В данной статье рассматривается возможность создания отечественного аналога периметра для офтальмологической диагностики полей зрения. Глаукома прогрессирует, не вызывая симптомов, пока заболевание не достигнет стадии тяжелого повреждения нервов. Для замедления прогрессирования заболевания необходимо раннее вмешательство и наблюдение за развитием течения болезни. Именно поэтому принято решение изучить возможность использования методов графической обработки периметрических изображений с дальнейшей возможностью использования методов машинного обучения.

Sensory activity of the brain is a necessary component of mental and physiological processes related to the perception of information and the occurrence of various diseases, including those related to the violation of peripheral boundaries of the visual field, retinal detachment, etc. with the eyes. This article considers the issue of creating a domestic analog of perimeter for ophthalmologic diagnostics of visual fields. Since glaucoma progresses without causing symptoms until the disease reaches the stage of severe nerve damage. To slow down the progression of the disease, early intervention and monitoring of the course of the disease is necessary. That is why we decided to study the possibility of using methods of graphical processing of perimetric images with further possibility of training a neural network.

Одной из положительных сторон внедрения лабораторных информационных систем (ЛИС) в медицинскую организацию, согласно плану Федерального проекта Минздрава РФ по созданию единого цифрового контура в здравоохранении, является возможность выгружать большие массивы данных лабораторных исследований и проводить их анализ. Цель работы — оценка возможности единого цифрового контура в обеспечении оперативного мониторинга углеводного обмена у лиц среднего, пожилого и старческого возраста в условиях COVID-19. В качестве материалов взяты первичные данные результатов лабораторных исследований из ЛИС «Ариадна.NLab» СПб ГБУЗ ГМПБ № 2 и запрошенные в Региональном фрагменте единой государственной информационной системы в сфере здравоохранения результаты лабораторных исследований пациентов поликлиники № 8. Анализ данных показал статистически значимое повышение уровня глюкозы в крови в ковидный период у всех возрастных категорий (р<0,05). В постковидный период по сравнению с доковидным регистрировали снижение уровня глюкозы у лиц среднего возраста (р=0,016), повышение — у лиц старческого возраста (р<0,001). Оборот структурированных электронных медицинских документов позволяет агрегировать статистические данные и обрабатывать их для получения динамических и аналитических отчетов. Результаты исследования свидетельствуют о наибольшем негативном влиянии COVID-19 на уровень глюкозы в крови у лиц пожилого возраста.

One of the positive aspects of the implementation of laboratory information systems (LIS) in a medical organization, according to the plan of the Federal project of the Ministry of Health of the Russian Federation to create a unified digital circuit in healthcare, is the emergence of the ability to download large amounts of laboratory research data and analyze them. The purpose of the work is to assess the possibility of a unified digital circuit in providing operational monitoring of carbohydrate metabolism in middle-aged, elderly and senile people in the context of COVID-19. The materials used are the primary data of laboratory research results from the LIS «Ariadna.NLab» of City Multidisciplinary Hospital № 2 and the results of laboratory tests of patients of Polyclinic №8 were requested from the GIS REGIZ. Data analysis showed a statistically significant increase in blood glucose levels during the covid period in all age categories (p<0,05). In the post-COVID period, compared to the pre-COVID period, a decrease in glucose levels was recorded in middle-aged people (p=0,016), an increase in elderly people (p<0,001). The circulation of structured electronic medical documents allows you to aggregate statistical data and process them to obtain dynamic and analytical reports. The study results indicate that COVID-19 has the greatest negative impact on blood glucose levels in older adults.
