Статья посвящена анализу деревянных весел эпохи раннего металла, обнаруженных на Горбуновском торфянике (хранятся в Нижнетагильском музее-заповеднике «Горнозаводской Урал»). Исследованы особенности их морфологии и технология изготовления. Проанализирован археологический контекст и новые данные (AMS-даты) о времени создания изделий. По количеству и качественному составу материала эта серия зауральских весел является самой представительной в мире для столь ранней исторической эпохи. Ее своеобразие заключается прежде всего в значительной однотипности (стандартизации) изделий, сохранении общих пропорций и параметров лопасти и рукояти, а также в фигурном оформлении наверший рукоятей. Отличительной чертой этой серии предметов можно считать и применение составной конструкции рукояти в некоторых изделиях. Комплексный трасологический и технико-технологический анализ весел позволил выявить приемы и способы их изготовления, ксилотомический — использовавшиеся породы древесины (сосна, кедр и ель). По сохранившимся следам обработки определен примерный состав основного инструментария. Деревянные весла, найденные на уральских торфяниковых памятниках, в целом подразделяются на две категории — количественно доминирующие цельные, сделанные из одной заготовки, и немногочисленные составные. В эпоху раннего металла в Зауралье деревообработка, вероятно, была традиционным видом деятельности со сложившимися приемами и способами.

В статье представлены первые результаты изучения палеолитического комплекса местонахождения Стойло (Усольский р-н Иркутской обл.) по итогам работ осенью 2021 г. Объект расположен на левом берегу р. Ангары и в рамках археологического районирования относится к Бельскому геоархеологическому району. Установлено, что комплекс залегал в доголоценовых отложениях, приуроченных к остаточному дресвяно-галечному панцирю, который подстилает солифлюциированная позднекаргинская–раннесартанская (?) толща. Анализ материала, представленного продуктами литорасщепления преимущественно кремнистых пород, свидетельствует об использовании призматического принципа раскалывания для получения небольших пластин. Орудийный набор характеризуется мелкоразмерными формами, включая орудия с шипом, резцы, ножи на пластинах с естественным обушком, пластины и отщепы с ретушью и следами утилизации, в сочетании с грубооформленным орудием на крупной гальке. Особенностью коллекции является то, что большинство артефактов несет следы корразии в виде слабого блеска поверхности. Это и приуроченность комплекса к дресвяно-галечной прослойке дает формальное основание отнести его к «макаровскому пласту». Однако совокупность технико-типологических данных и интерпретация строения разреза позволяют предложить в качестве рабочей гипотезы датировку палеолитического комплекса Стойла средним этапом верхнего палеолита / раннесартанским временем. Для подтверждения этого предположения необходимы дальнейшие раскопки с целью пополнения коллекции и массива естественно-научной информации.

Published: December 2023

В статье представлены результаты изучения петроглифов, выявленных с применением программ Agisoft и 3D Studio Max на стенах пещеры-убежища Ана-Зага — самой большой в Гобустане. Рассматриваются стилистические особенности изображений разных периодов; приводятся данные радиоуглеродных исследований культурных слоев. Определены хронологические этапы эволюции наскальной живописи. По геологическим данным о трансгрессиях и регрессиях Каспийского моря установлено время первого заселения пещеры-укрытия Ана-Зага человеком. Указан видовой состав вымерших животных, образы которых нашли отражение в петроглифах. Сделан вывод о том, что в неолите и энеолите с поднятием уровня Каспийского моря пещера-укрытие Ана-Зага оставалась основным местом проживания людей. С понижением уровня моря в бронзовом веке были заселены средние и нижние террасы. В ходе освоения новых пространств менялись сюжеты петроглифов.

В статье предлагается опыт построения хронологии наскальных изображений, обнаруженных на территории российско-монгольской части Горного Алтая, от эпохи палеолита до позднего Средневековья. Исследование базируется на анализе стилистики и репертуара сюжетов петроглифов, а также результатах изучения петроглифических палимпсестов. Древнейший пласт наскального искусства указанного региона отнесен к эпохе верхнего палеолита. На ряде палимпсестов фигуры лошадей, выполненные в калгутинском стиле, перекрыты петроглифами бронзового века. Отмечается наибольшая сложность определения пласта изображений, относящихся к неолиту. В огромном массиве петроглифов эпохи бронзы выделены фигуры, отражающие изобразительные традиции, которые связываются с афанасьевской и чемурчекской культурами. Очевидным маркером чемурчекской изобразительной традиции являются «чемурчекские антропоморфы». Указывается, что пласт петроглифов эпохи бронзы, представленный многообразием зоо- и антропоморфных фигур, а также изображений реалий (оружие, колесный транспорт), не является хронологически и культурно монолитным и в дальнейшем может быть дифференцирован хронологически. Для раннего железного века предполагается выделить петроглифы начального этапа и середины I тыс. до н.э. Рассмотрены сложности определения наскальных рисунков гунно-сарматской эпохи, а также своеобразие яркой древнетюркской изобразительной традиции эпохи раннего Средневековья, содержание петроглифов Новейшего времени на юге Российского Алтая.

Published: December 2023

В статье рассматривается структура кладбищ и типы надмогильных сооружений на региональном материале традиционной культуры русских староверов-беспоповцев, проживающих в Усть-Цилемском р-не Республики Коми. Впервые представлено описание староверческих погостов, получивших в местной среде названия «могильники», «могилы», история их формирования и сохранения. Освещаются традиционные представления, касающиеся кладбищ, их обустройства. Подробно анализируется символика форм надмогильных сооружений, выполненных не только на основе церковных предписаний и требований, но и с учетом дохристианских верований. В исследовании используется народная терминология, поверья об усопших и загробной жизни. Рассматриваются степень и характер трансформаций в годы советского строительства, предопределившего грандиозную модернизацию общества и в известной мере изменившего традиционные устои староверческой культуры нижнепечорцев. Несмотря на стремление представителей этноконфессиональной группы устьцилёмов следовать традициям предков, в 1960-1970-х гг. они стали испытывать влияние советской культуры, но сумели сохранить локальную специфику, выраженную в типах надмогильных сооружений, традиционных представлениях и обрядности. Установлено, что способы организации и обустройство кладбищ, важнейшие символы, зафиксированные в памятниках, свидетельствуют об устойчивости народной культуры усть-цилемских староверов, синтезировавшей церковные предписания и правила и элементы дохристианских верований. В научный оборот вводятся новые полевые этнографические, фольклорные, лингвистические и архивные материалы.

Purpose: This study aimed to determine the clinical, laboratory, imaging, and bacteriological features of bone and joint infections in children and to identify their characteristic features for early diagnosis.

Materials and Methods: In this retrospective study patients diagnosed with osteomyelitis and septic arthritis, based on established guidelines, were included. We collected demographic, clinical, and imaging data, along with inflammatory markers and microbiological data, and any invasive procedures performed by orthopedic surgeons. We also reviewed the development of long-term sequelae, the duration of treatments, and the types of antibiotics used for both oral and parenteral therapy.

Results: The study group consisted of 25 patients with osteomyelitis, 10 with septic arthritis, and 5 with combined infection (osteomyelitis and septic arthritis). Inflammatory marker levels were abnormal in most children. The most commonly identified organism was the Staphylococcal species. Radiological findings compatible with bone and joint infections were detected in all patients whose magnetic resonance imaging results were available. Invasive procedures were performed in 44%, 90%, and 100% of the patients with osteomyelitis, septic arthritis, and combined infection, respectively.

Conclusion: Sensitivity increased when all the markers were used together. Magnetic resonance imaging considered the most informative imaging modality for bone and joint infections provided the highest sensitivity in our study. These sensitive indicators can be helpful for the early diagnosis and long-term follow-up of patients with unclear presentations.

Authors: YURTERİ Ahmet , MERCAN Numan , KILIÇ Mehmet , YILDIRIM Ahmet
Published: December 2023

Purpose: The objective of this study is to evaluate the influence of patient positioning on intraoperative outcomes, specifically intraoperative time, fracture reduction, and implant location, in individuals with trochanteric femur fractures undergoing intramedullary nailing. The study compares two patient positions: the lateral decubitus position (LDP group) and the utilization of a traction table (TT group).

Materials and Methods: A total of 82 patients with trochanteric femur fractures, who underwent surgery were included. The patients were divided into LDP and TT groups. Various parameters, including age, gender, fracture details, setup time, operation time, anesthesia time, fluoroscopy time, tip-apex distance (TAD), collodiaphyseal angle (CDA), reduction quality, and implant position, were analyzed.

Result: Surgical time in the LD group was 33.90 ± 6.05 minutes, whereas in the TT group, it was 33.00 ± 6.64 minutes. Anesthesia time was 50.55 ± 7.46 minutes in the LD group and 55.26 ± 12.49 minutes in the TT group. Fluoroscopy time in the LD group was 45.20 ± 7.18 seconds, while in the TT group, it was 46.23 ± 4.50 seconds. Lateral decubitus position resulted in shorter setup and anesthesia times compared to the traction table.

Conclusion: Intramedullary nailing in the lateral decubitus position is a viable and practical choice for fracture reduction, with the potential to decrease morbidity and mortality rates especially in elderly patients.
Exploring the drug repurposing potential of silymarin beyond hepatotoxicity treatment through WNT/β-catenin signaling pathway
Authors: GÜLTEKİN Sümeyra
Published: December 2023

Purpose: In this study, the potential of silymarin as a drug for hepatocellular carcinoma (HCC) was evaluated in situ.

Materials and Methods: The SwissADME tool was utilized to assess the pharmacokinetic and drug-like properties of silymarin. Molecular docking was performed to model the interaction of silymarin with molecular compounds known to play a role in the WNT/β-catenin pathway and associated with this pathway in HCC. Target proteins (AFP, PIK3CA, β-catenin, PTEN, AAT, AXIN1, GSTM1, GSK3B, PI3K3CA, GSTT1, CCND1, albumin, p53, MET, CTNNB1, and APC) were obtained from the SwissTargetPrediction database. Protein-protein interactions were obtained from the STRING and Cytoscape databases. The PASS platform was used to predict potential bioactivity properties.

Results: The study data revealed that silymarin exhibited the highest binding affinity to the APC protein, with a value of -11.7 Kcal/mol. Although AXIN1 showed the least binding among the studied proteins, with a value of -7.4 Kcal/mol, this can still be considered a good binding affinity.

Conclusion: This study demonstrated the potential of silymarin to inhibit the overactivation of the WNT/β-catenin pathway and identified silymarin as a potential drug candidate for HCC, beyond its hepatoprotective properties. However, further preclinical and clinical studies targeting the WNT/β-catenin pathway are required to confirm the effectiveness and safety of silymarin.

Helianthus Annuus L. Comparison Of The Properties Of Fibers Obtained From The Plant By Methods of Decortication And Retting
Authors: ATAMAN Nilsu , ŞIK Levent
Published: December 2023

A large amount of sunflower production is carried out in our country. The 2,500,000 tons of sunflower stalks that appeared after production pose a problem for our farmer. In order to clean up this environmental problem from the field, sunflower stalks are destroyed by burning to warm up in winter, broken down and mixed into the soil, or burned after harvesting. It is thought that by obtaining qualified, ecological and naturally decomposing sunflower fiber from the stem of the sunflower plant, which is an agricultural waste, it can increase the added value of agricultural products and contribute to the protection of the environment. In this study, the anatomical characteristics of the stem of the sunflower plant were determined, and natural lignocellulosic fibers were obtained from the sunflower stem by retting and decortication methods (fresh stem, dried stem). Various physical, chemical and mechanical properties of these fibers have been measured. For this purpose, FTIR (Fourier Transform Infrared Spectroscopy) analysis, XRD (X-Ray Diffractometer) analysis and SEM (Scanning Electron Microscope) analysis were applied to the fibers obtained by different methods. Thermal analyses were performed by TG-DTA (Thermogravimetric) analysis. In addition, fiber strength, fiber fineness, fiber length and color measurements were made. The chemical content of the obtained fibers (pectin, lignin, cellulose, hemicellulose) was determined. The properties of the fibers were compared using the obtained data. As a result of the study, it has been seen that the characteristic properties of the sunflower fibers obtained by the retting method are better. It has been determined that the elemental, thermal and crystal structures of the fibers obtained by different methods are similar. It was concluded that sunflower fiber will not be spun as a yarn, but can be used as a natural polymeric composite reinforcement material.

Published: December 2023

The study was conducted to evaluate the level of disaster resilience and preparedness among the members of the MDRRMC and BDRRMC in the Municipality of Alabel, Sarangani Province. Descriptive-correlative research design were utilized employing quantitative method. Data were gathered through survey questionnaires administered to 219 respondents. Key Informant Interviews were conducted among 9 members of the BDRRMC to triangulate the quantitative data. The gathered data were analyzed using frequency, percentage, weighted mean, and Pearson correlation. The findings of the study revealed that there was a proportional number of male and female respondents of which majority of them belong to adult aged group. Majority of the respondents are government employees and government officials who are college graduates. The level of disaster resilience of the respondents in terms of the five areas on governance, risk assessment, knowledge and education, risk management and vulnerability reduction, and disaster preparedness and response are relatively high with a verbal description of high resilience. On the level of disaster preparedness among the respondents, the results revealed that the members are always prepared based on the four areas for likelihood of being impacted by a national hazard, vulnerability of physical structures, people, and livelihoods, barangay-level planning and individual’s preparation for disaster, and individual’s sense of control over their own lives and their ability to participate and influence their community and government. In relation to the disaster resilience and preparedness experiences, three themes emerged in this study as perceived by the informants and these are: (1) Planning and Preparation, (2) Issues and Challenges, and (3) Coping Mechanism. Generally, there is a moderate positive correlation between disaster resilience and disaster preparedness among the respondents (r= .449).
Impact of solar photovoltaic technology on GHGs reduction - a case study in Jordan
Authors:   Jordan University of Science and Technology, Darwish Haneen , Darwish Walaa ,   Yarmouk University
Published: December 2023

The global warming phenomenon, primarily caused by the emissions from conventional energy sources, has become a pressing concern worldwide. Greenhouse gases (GHGs), particularly carbon dioxide (CO2), emitted into the atmosphere contribute significantly to this issue. They have diverse impacts on climate, ecosystems, public health, and socio-economic systems, highlighting the need for comprehensive mitigation and adaptation strategies. To address this problem and minimize GHG emissions, renewable energy sources have emerged as the most promising alternative for power generation. These sources offer a sustainable and clean alternative to fossil fuels, mitigating climate change, reducing air pollution, and fostering energy independence. In the context of this study, a 100 kW solar photovoltaic (PV) station was proposed in Ma’an, Jordan, as a sustainable solution. The effectiveness of this PV station in mitigating GHG emissions was evaluated by comparing it to a base case involving an oil station. To perform this analysis, RETScreen software, a widely recognized tool for assessing renewable energy projects, was used to examine the environmental impact of switching from a conventional energy system to a renewable energy system. The results obtained from the analysis revealed a remarkable reduction in annual gross GHG emissions in the proposed case compared to the base case. Specifically, the emissions would be reduced by 89%, translating to an annual reduction of 49.9 tonnes of CO2. These findings underscore the significant potential of the proposed solar PV station in curbing the emissions responsible for global warming. By significantly reducing GHG emissions, the solar PV station contributes to creating a more sustainable future, aligned with the principles of environmental preservation and climate change mitigation.

Published: December 2023

El artículo desarrolla una secuencia descriptivo-analítica que identifica las debilidades conceptuales de diversos modelos de comunicación fundados en la subjetividad, la hermenéutica y las teorías del emisor, cuya hegemonía se mantiene estable en las mediaciones antropológicas. Todo ello en medio de los intensos cambios que ha significado el complejo concepto de Antropoceno. En efecto, el centro gravitacional del análisis se sitúa en los postulados del giro anti-hermenéutico, donde la estructura es la base de la sensibilidad humana, y una concepción materialista de los medios que se aparta de la fenomenología y el discurso antropológico. La arqueología de los medios trabaja con materias primas, soportes, infraestructuras, máquinas mediales que distan del análisis cualitativo y los paradigmas complejos del antropoformismo que han sido prominentes en autores de la relevancia de Marshall McLuhan. En el ámbito de la contemporaneidad, esto nos lleva a distinguir entre una geología medial y medios de comunicación, mediante algunas tesis sustanciales de autores como Friedrich Kittler y Jussi Parikka.
When child trafficking and informal fostering intersect
Authors: Cody Anna M , Okech David , Yi Hui , Aletraris Lydia , Clay-Warner Jody , Callands Tamora
Published: December 2023

Informal fostering is an important tradition for many communities in Sub-Saharan Africa. However, the intersections of poverty and social circumstances may increase the risk of exploitation for informally fostered children. We used mixed methods to estimate the prevalence of child trafficking within informal child fostering placements in Sierra Leone, to document vulnerability factors and explore perceptions of key stakeholders. Data were collected through 1) a household survey (N= 3,070), 2) interviews (N= 41) with young adults who experienced child trafficking in informal fostering, parents of children who experienced trafficking in foster placements, and key informants, and 3) focus groups with community members (N= 23). We found that informal fostering increases the likelihood for children to experience trafficking. Although there are significant associations between child trafficking and informal fostering, social (gender and cultural traditions) and economic factors (poverty and school access) appear to be drivers for both. Our results suggest that strengthening poverty reduction measures, expanding opportunities for schooling and vocational training for children and young adults, and improving safety for children in informal fostering arrangements through reporting and monitoring are essential to mitigate the high rates of child trafficking in Sierra Leone, and to ensure children’s well-being in informal fostering placements.

Organizations cannot survive and achieve their long-term goals without considering carefully designed and coordinated managerial systems. Which include human resources. Human resource management is vital part of the chain of value creation in many industries, including the tourism and hospitality industry. Human resources of high quality and in sufficient quantity in this industry are vital and lie in a core of its value chain as far as the tourism industry embraces the combination of economic, social and emotional interactions and complex processes, as well as aesthetics and information that can be less important in other industries, and these characteristics are part of human nature and soft skills of the human resources involved in the industry. In the age of marketing and intensified competition the role of human resources is not to be underestimated. Therefore, the purpose of our study is to determine how the human resource factors affect the organizational culture (socialization) and to examine the profitability in the tourism industry in the context of human resource management. The research data was collected from 30 enterprises active in the field of tourism and hospitality including hotels, restaurants, entertainment centers and services in Jakarta of Indonesia in 2022. According to the purpose of the research, the employees of those companies were considered as a statistical sample, whose number was 300 people. In the study we tested the influence of ten factors from the field of human resource management on business profitability. The significance of the factors’ influence was examined using the one-sample T-test at the 95% confidence level and all of them were confirmed. In addition to the T-test, ANOVA has also been used to complete the research results; According to the results of the ANOVA test, there was no significant difference between the opinions of officials and economic experts based on the factors of age, level of education, work experience, attendance and duration at training courses. However, based on the factor of organizational position, the admissions officers evaluated the effect of performance management on profitability as the main indicator.

The research aims to reveal policies in labour migration in providing job placement services, economic, legal, and social protection. The novelty in the research is to provide an academic argument so that the management of the placement of The Welfare of the Indonesian Migrant Workers (TKI) becomes a priority for each region, not even considering this as a trivial and secondary issue, eliminating the budget, not preparing competent resources in their field. This research was conducted using the qualitative descriptive method in various regions in Indonesia that have and do not have integrated services (ISs). The data was obtained by observing the areas of North Sumatra, Bali, West Nusa Tenggara, and East Nusa Tenggara. Immigration has led to the practice of daily trips for employment, the diversification of the income pattern of the village, the capitalization of the land and housing of the village, the transformation of the productive foundations of the village, and the penetration of lack of motivation in engaging in agricultural activities. The benefit of the existence of integrated services is the reduction of the number of illegal migrant workers departures. However, North Sumatra Province does not yet have an integrated services and only uses the Ministry of Manpower application. The existence of integrated services in the regions has become ineffective because the internet network is not supported, and human resources are inadequate. The ineffectiveness of the services provided can result in Indonesian irregular migrant workers being very vulnerable to becoming victims of exploitation abroad.

The SPSE e-procurement application has been used to suppress procurement corruption that often occurs in the Indonesian government. However, procurement corruption still occurs, allegedly the cause is due to the existence of a weak anti-fraud policy (AFP) in Indonesian government ministries and agencies. This study aims to prove empirically, whether there is an influence of AFP, on reducing corruption in the public e-procurement system with an approach to improving the health of the e-procurement system through proactive fraud detection with a forensic accounting technique approach. This research uses Quantitative Research Methods, research data is collected through questionnaire instruments, face-to-face interviews, and focus group discussions (FGD) which are carried out in 82 Ministries and agencies in Indonesia in 2022. Sampling using census techniques. The data were analyzed using a Structural Equation Modeling (SEM) approach assisted by the application of Lisrel 8.80. The results showed that anti-fraud policy has no significant effect on proactive fraud detection, anti-fraud policy has a positive and significant effect on reducing public e-procurement corruption, anti-fraud policy indirectly has a positive and significant effect on reducing corruption in public e-procurement through proactive fraud detection.

A Lei Geral de Proteção de Dados, LGPD, Lei nº 13.709/18, buscou alinhar o Brasil ao standard mundial sobre proteção de dados, trazendo para nossa realidade social uma mudança de perspectiva acerca da forma de pensar e agir quando falamos sobre dados pessoais. Este trabalho busca trazer uma breve contextualização a respeito da utilização de dados na sociedade atual em paralelo com a existência da LGPD, demonstrando empiricamente a relevância da matéria para a manutenção da relação das empresas com potenciais consumidores, e como o desenvolvimento da cultura de proteção de dados dentro da organização pode influenciar diretamente na relação consumidor/empresa como mecanismo de fidelização do cliente com a marca. Desse modo, foram observados o conhecimento de potenciais consumidores sobre a LGPD e a importância dada à proteção de seus dados pessoais. Buscou-se ainda entender o comportamento destes diante de casos práticos, e os benefícios que as empresas podem agregar quando da aplicação da cultura de proteção de dados e da implementação do programa de privacidade na sua organização.
