Published: July 2024

The government has launched the Student Entrepreneurship Development Program (P2MW) to boost entrepreneurship in Indonesia. This study examines how entrepreneurial education, experience, and innovation influence entrepreneurial intentions and readiness to start a business. The research employs a descriptive method, using 80 students who received P2MW grants as samples. Data were collected through online and offline questionnaires using purposive sampling and analyzed with SEM-PLS using SmartPLS 4.0 software. The findings indicate no significant effect of entrepreneurial education on entrepreneurial intentions. However, entrepreneurial experience and innovation positively and significantly influence entrepreneurial intentions. The results also show a positive and significant impact of entrepreneurial intentions on readiness to start a business. This study recommends that the Ministry of Education and Culture encourage universities to create an entrepreneurial ecosystem within their environment to enhance students' readiness to start their businesses.

The Relationships of Dust and Total Masses of Luminous Infrared Galaxies with Their Far Infrared and Total Luminosities Using Two Methods of Distance Measurements
Authors: Shaker Farah Z. , Al Najm M. N.
Published: July 2024

This research aims to determine the nature of the relationships among luminous infrared galaxies (LIRGs) by using different methods of distance measurement (distance modulus “dm” and luminosity distance “dl”). We used data from the following sources: NASA Extragalactic Database (NED) and the HYPERLEDA database, where this data was used to study the nature of the relationships and the extent to which they relate to each other. The program (statistica-win-program) was employed, which helped us know the strength of the association between the variables. The results of the statistical analysis showed that there was a strong correlation between dust mass (Mdust dm & Mdust dl) and luminous infrared (LFIRdm, LIRdm) & (LFIRdl, LIRdl), where the partial correlation coefficient was equal to (R⋍0.7) and the slope was linear. There was also a positive correlation between (LFIRdm, LFIRdl)& ( ) where the partial correlation coefficient was (R⋍0.4) with a linear slope. The relationship between (LIR)& ( ) was a positive relation in the modulus distance case (dm), where its correlation was equal to (R⋍0.4), but in another case (luminosity distance), the relation was very weak, and the correlation was (R⋍0.2). The relationship between total masses ( ) & (LFIRdm, dl­­) in both cases of distance (dm) & (dl) was good, and the partial correlation coefficient was equal to (R⋍0.4) with a linear slope. The relationship between (LIR) & ( ) in both cases of distance was also positive, and the partial correlation coefficient was equal to (R⋍0.3). There was an inverse relationship between the ratio fluxes (F100/F60) & ( ), as well as a very tight partial correlation coefficient, which was  equal to (R⋍-0.9) with a slope of (-1).

Published: July 2024

Unmanned aerial vehicle (UAV) systems have become crucial for gathering information for observation, surveillance, mapping, and 3D modeling tasks. The use of UAVs in close and mid-range sectors has shown potential for cost-effective alternatives to traditional aerial photogrammetry conducted by humans. The research aims to optimize photogrammetric processing for drone-based 3D mapping by examining strategies and applications to increase accuracy and efficiency. The study highlights the significance of image overlap and high-quality camera equipment to obtain reliable outcomes for stereo-photogrammetry and depth measurements. Drones and specialized software like 3DF Zephyr and Pix4D were used to create a 3D map. The software uses automatic structure from motion techniques, including feature extraction, image matching, and bundle block adjustment, to produce a dense point cloud that forms the basis for the 3D model. A DGPS system was implemented to enhance spatial accuracy. The map initially showed inadequate accuracy, with an error rate exceeding 80cm. However, with the use of a DGPS system, the error was reduced to less than 3cm. This study provides suggestions and insights for improving photogrammetric processing for drone-based 3D mapping.

Authors: Patil Manisha M , Rafique Aejaz A A
Published: July 2024

Sorafenib tosylate (SFN) is a tyrosine kinase inhibitor used clinically to treat liver, kidney, and thyroid carcinoma. This research aims to accurately quantify SFN using a quality-by-design (QbD) approach with RP-HPLC. Chromatographic settings were optimized using a Box-Behnken design, measuring responses such as retention time, tailing factor, theoretical plate, and peak area. At the same time, independent variables were flow rate, mobile phase composition, and wavelength. A C18 column (4.6 × 250 mm, 5 µm) served as the stationary phase, with a mobile phase of methanol and 0.1% o-phosphoric acid in a 41:59 v/v ratio. SFN detection occurred at 267 nm in isocratic mode at a flow rate of 1.1 mL min−1. Method validation followed International Council for Harmonization guidelines, yielding a coefficient of determination (R2) of 0.9998, indicating linearity in the 5-25 µg mL−1 range. Results showed detection (LOD) and quantification (LOQ) limits of 0.04 and 0.12 µg mL−1, respectively. Additionally, the method demonstrated precision, accuracy, and robustness consistent with ICH criteria. Overall, this simple, accurate, rapid, and robust RP-HPLC method is suitable for routine SFN analysis in various formulations.

A note on hamiltonicity conditions of the coprime and non-coprime graphs of a finite group
Authors: Huda Muhammad Nurul
Published: July 2024

Let $G$ be a group. The coprime and non-coprime graphs of $G$ are introduced by Ma et al. (2014) and Mansoori et al. (2016), respectively, when $G$ is finite. By their definitions, which refer to coprime and non-coprime terms of two positive integers, those graphs must be related. We prove that they are closely related through their graph complement and preserve the isomorphism groups. Furthermore, according to Cayley's theorem, which states that any group $G$ is isomorphic to a subgroup of the symmetric group on $G$, it implies that the studies of the coprime and non-coprime graphs of any group $G$ (especially, when $G$ is finite) can actually be represented by the coprime and non-coprime graphs of any subgroup of the symmetric group on $G$. This encourages us to specifically study the hamiltonicity of both kinds of graphs associated with $G$ when $G$ is isomorphic to the symmetric group on $G$.

Published: July 2024

Objective: The purpose of this study was to determine dental archs’ shape, and to describe differences in transversal dimensions and archs’ depths in mixed dentition, in order to know occlusal harmony arrangement in a native student population from Leticia, Amazonas, Colombia. Methods and materials: A cross-sectional study with 64 students (32 boys and 32 girls) distributed in two groups: 31 students with early mixed dentitions and 33 students with belated mixed dentitions between 6 and 12 years old was carried out. Studied variables were measured from plaster cast study models. Results: Oval upper arch was found in 86% of students while 14% had squared upper arch. Proportions for lower arch shape were 75% oval and 25% squared, respectively. Most of the transversal dimensions had differences in both groups. Inferior intercanine distances were constant. Depth, width and length measurements are evidence of harmonic dental arch development for Amazonian children. Discussion: This ethnic group had higher oval arch shape prevalence, followed by squared arch shape There were differences for all arch depth measurements, mainly in anterior sector due to the susceptibility to environmental factors in mixed dentition period. Conclusions: Occlusal harmony in this population is a result of arch shape, as well as transversal and depth changes physiologically normal.
Policy Brief No. 1. Comprehensive neighbourhood upgrading as a strategy for the transition towards urban territorial peace
Authors: Ortiz-Arciniegas Catalina , Franco-Calderón Ángela María
Published: July 2024

Considering that in Colombia most of the victims of forced displacement looked for shelter in the cities, the urban dimension should be included in the processes of reparation and restitution of rights within a transitional and restorative justice framework. Under this approach, Comprehensive Habitat Upgrading (CHU) becomes relevant as a strategy for the construction of urban territorial peace. This tool contributes to the consolidation of fairer cities through the provision of adequate housing, basic urban services, and access to the opportunities in self-built popular neighbourhoods, and may support the victims of the internal conflict in their search for settlement, identity, and memory. This policy brief provides public policy recommendations for decision makers to articulate CHU and peacebuilding with a rights-based, differential and intersectional approach that allows to assist both vulnerable urban communities and multiple subjects of reparation who came to the cities in search of new life opportunities.

Published: July 2024

Latinoamérica y el Caribe (LAC) es la región más desigual del mundo (CEPAL, 2022). Esta condición, sumada a la poca capacidad de respuesta de los Estados a condiciones como la pobreza, la inseguridad, el desempleo y la falta de vivienda digna, ha hecho que muchas personas vean la autogestión como la opción más viable para tener un techo. Los barrios populares que emergen como resultado de la producción social del hábitat no solo se constituyen en la expresión físico-espacial de un proyecto mancomunado para construir viviendas, sino también en expresiones sociales y culturales de la vida colectiva que se manifiestan en el territorio con la apropiación y resignificación de espacios públicos, pensados como los lugares de encuentro, goce colectivo, diversidad, deliberación pacífica y garantía de derechos. Dada la relevancia de estos espacios para la vida comunitaria, este Policy Brief presenta una serie de recomendaciones para el diseño participativo, activación y sostenibilidad de los espacios públicos como aporte a los procesos de mejoramiento integral del hábitat.

Published: July 2024

América Latina y el Caribe (ALC) es la región más desigual del mundo (PNUD, 2019), donde un tercio de la población vive en condiciones de pobreza. Los barrios donde reside esta población están marcados por estigmas propagados por el Estado y los medios de comunicación, que se relacionan con regímenes de visibilidad (violencia, precariedad, ilegalidad) e invisibilidad (creatividad, espíritu comunitario, cuerpos diferentes). Estos regímenes se alimentan de las asimetrías en la forma en que los territorios periféricos son conocidos por los datos recopilados por gobiernos y corporaciones. Los datos son una parte esencial de los dispositivos tecnopolíticos construidos para la gestión de las ciudades, desde los servicios públicos hasta las grandes infraestructuras urbanas. Este documento ofrece ideas y recomendaciones sobre cómo la Generación Ciudadana de Datos (GDC) puede incluir a la población de los territorios periféricos en el ámbito de la gestión urbana mediante la politización de las tecnologías urbanas a través del activismo digital.
Regional variation in prevalence of frailty in India: Evidence from longitudinal ageing study in India (LASI) wave-1
Authors: Nagarkar Aarti , Kulkarni Amruta Shantaram
Published: July 2024

Background & objectives

Frailty is a geriatric syndrome with clinical and public health implications. It represents the state of increased vulnerability. This study aimed to estimate the prevalence of frailty and pre-frailty by demographic characteristics and geographical regions in India. Furthermore, it also aimed to examine the association of this prevalence with selected health outcomes using data from the Longitudinal Ageing Study of India (LASI).

Methods

This is a secondary analysis of LASI wave-1 data. A total of 26,058 respondents aged ≥60 yr were included for analysis. Frailty was assessed using Fried’s frailty phenotype, including slowness, shrinking, low physical activity, weakness, and low endurance. Descriptive statistics were used to study frailty distribution. The odds ratio (OR) of health events across the frailty categories was computed using ordinal logistic regression.

Results

The findings of this study suggest that the prevalence of frailty and pre-frailty was 29.2 and 58.8 per cent, respectively. The prevalence of frailty was higher among women (37.3%), illiterate (37%) and rural residents (31%). It ranged between 14.5 per cent in Uttarakhand and 41.3 per cent in Arunachal Pradesh. Frailty was strongly associated with depression [OR: 2.09, Confidence Interval (CI): 1.98–2.21] and activities of daily living (ADL) difficulty (OR: 1.75, CI: 1.64–1.86). Higher odds were reported for fracture (OR: 1.24, CI: 1.01–1.51) and multimorbidity (OR: 1.18, CI: 1.04–1.33) among frailty.

Interpretation & conclusions

The heterogeneity of frailty prevalence across States indicates the need for population-specific strategies. A sharp age-related increase in prevalence highlights the need for preventive measures. Furthermore, the high prevalence of frailty among women, illiterate and rural residents indicates the target population for receiving preventive interventions. Lastly, a heterogeneity in frailty prevalence across different States indicates the scope for region-specific programmes.

Published: July 2024

Нормативно техническая документация, регламентирующая оценку безопасности использования летательных аппаратов с авиационными средствами поражения не перерабатывалась более 25 лет. За это время появились новые системы измерений, новые средства имитации электромагнитных полей, изменился подход к проведению испытаний. Назрела необходимость переработки нормативно технической документации. Учитывая, что сдаточные электромагнитные испытания в процессе проведения которых выполняется оценка безопасности использования летательных аппаратов с авиационными средствами поражения требуют значительных финансовых и временных затрат на основе анализа материалов испытаний разработаны предложения по корректировке НТД с целью сокращения сроков и стоимости испытаний без ухудшения качества.

Normally, technical documentation regulating the assessment of the safety of the use of aircraft with aerial weapons has not been processed for more than 25 years. During this time, new measurement systems, new means for simulating electromagnetic fi elds appeared, and the approach to testing was changed. There is a need to rework normative technical documentation. Taking into account that the commissioning electromagnetic tests during which the assessment of the safety of the use of aircraft with aircraft means of destruction is being carried out requires considerable financial and time-consuming costs, based on the analysis of test materials, proposals have been developed for the adjustment of NTDs in order to reduce the time and cost of testing without deteriorating the quality.

Антропогенное изменение ландшафта – это изменение его свойств под влиянием антропогенных воздействий и выражается в изменениях структуры земной поверхности. По происхождению и степени видоизменения природного облика ландшафты подразделяют на природные, освоенные (измененные) и искусственные (антропогенные). Природные ландшафты не преобразованы человеческой деятельностью, они подчиняются законам естественного саморазвития природных экологических систем. Освоенные – это частично преобразованные ландшафты. В условиях искусственного ландшафта природный комплекс преобразован и видоизменен деятельностью человека в такой степени, что можно говорить о сложении нового комплекса компонентов. Последние классифицируются на техногенные (промышленные), сельскохозяйственные, городские (урбанистские), рекреационные. Как любое антропогенное воздействие на природную среду, антропогенное изменение ландшафта может быть разрушительным (деструктивным), стабилизирующим и или конструктивным. Определение оптимального соотношения разных по степени антропогенного изменения типов ландшафтов – важная стратегическая задача природопользования в настоящее время.

Anthropogenic change of the landscape is a change in its properties under the influence of anthropogenic influences and is expressed in changes in the structure of the earth’s surface. According to the origin and degree of modification of the natural appearance, landscapes are divided into natural, developed (modified) and artificial (anthropogenic). Natural landscapes are not transformed by human activity, they obey the laws of natural self-development of natural ecological systems. Developed landscapes are partially transformed landscapes. In the conditions of an artificial landscape, the natural complex has been transformed and modified by human activity to such an extent that we can talk about the addition of a new complex of components. The latter are classified into technogenic (industrial), agricultural, urban (urban), recreational. Like any anthropogenic impact on the natural environment, anthropogenic changes in the landscape can be destructive (destructive), stabilizing and or constructive. Determining the optimal ratio of landscape types that differ in the degree of anthropogenic change is an important strategic task of nature management at the present time.

Рассмотрены результаты исследований воздействия одиночного шторма на прибрежную зону в районе 104...109 км федеральной автодороги Южно-Сахалинск–Оха. Оценена энергия и структура инфрагравитационных волн (ИГ), ответственных за разрушение берегов и образование ритмических форм рельефа по данным сети регистраторов уровня, установленных вблизи, на морское дно с. Взморье. Показано, что формируется стабильная система инфрагравитационных волн с периодами от 120 до 160 с, моделирующая прибрежные формы рельефа. Проведены батиметрические съемки до и после прохождения одиночного циклона. При этом в области наблюдения зарегистрированы отрицательные величины разностной батиметрии. Поскольку многолетнего углубления прибрежной зоны не наблюдается, следует, что восстановление берегового уклона происходит за счет разрушения материала берега, что и приводит в конечном итоге к его обвалу в море и частичному разрушению асфальтированного полотна автомобильной дороги.

The results of studies of the impact of a single storm on the coastal zone in the 104...109 km section of the federal highway Yuzhno-Sakhalinsk–Okha considers in the paper. The energy and structure of the infragravity waves responsible for the destruction of the shores and the formation of rhythmic relief forms are estimated from the data of a network of level recorders installed near the v. Vzmorye. It is shown that a stable system of infra-gravity waves with periods from 120 to 160 s, modeling coastal forms of relief, is being formed. Bathymetric surveys were carried out before and after the passage of a single cyclone. At the same time negative values of the difference bathymetry were registered in the observation area. Since there is no long-term deepening of the coastal zone, it follows that the restoration of the coastal slope is due to the destruction of shore material, which ultimately leads to its collapse in the sea and partial destruction of the asphalt surface of roadway.

В настоящей работе разрабатывается алгоритмическое и математическое обеспечение обработки изображений, получаемых с помощью георадарарного комплекса. Предлагаемый подход к обработке изображений образов для последующего определения инженерно-механических характеристик грунта, наличия в нем областей обводнения и разуплотнения грунта, пустот, инженерных коммуникаций, каменной кладки, бетонных элементов, подземных ручьев основан на агрегировании методов определения параметров отраженных электромагнитных волн, использования размытия изображения в качестве информативного критерия, определяющего состояние реального объекта, и алгоритмов построения контура подземного элемента с отличающимися свойствами электропроводности и диэлектрической проницаемости. Предлагаемые решения могут быть реализованы в программно-аппаратном комплексе, используемом для построения и быстрой обработки георадиолокационных профилей участков, расположенных в полосе отвода железнодорожных магистралей.

In this paper, algorithmic and mathematical support for processing images obtained using a georadar complex is being developed. The proposed approach to image processing of images for the subsequent determination of engineering and mechanical characteristics of the soil, the presence in it of areas of flooding and soil decompression, voids, utilities, masonry, concrete elements, underground streams is based on the aggregation of methods for determining the parameters of reflected electromagnetic waves, the use of image blurring as an informative criterion determining the state of a real object, and algorithms for constructing the contour of an underground element with different properties of electrical conductivity and dielectric permittivity. The proposed solutions can be implemented in a hardware and software complex used for the construction and rapid processing of georadolocation profiles of sections located in the railway right-of-way.

Данная статья посвящена исследованию влияния исламского фактора на взаимоотношения Киргизской Республики и Российской Федерации в начале XXI века. Авторы акцентируют внимание на стремлении двух государств к обеспечению безопасности, противодействию терроризму, экстремизму и дальнейшему распространению радикальных идей. Вторжение Исламского движения Узбекистана на территорию Киргизской Республики стало сильным импульсом для дальнейшего тесного сотрудничества двух государств и нашло отражение в подписании Декларации о вечной дружбе, союзничестве и партнёрстве. Основание же Организации Договора о коллективной безопасности и последующие Соглашения о статусе и условиях пребывания Российской авиационной базы на территории Киргизии, также стали способствовать сохранению безопасности. Несмотря на неконституционную смену власти в Киргизской Республике в 2005 г. и 2010 г., и как следствие, резкое возрастание активности религиозных организаций, Россией начинают приниматься решения по совершенствованию деятельности ОДКБ и созданию объединённой российской базы в Киргизии, что позволяет сказать о заинтересованности в ликвидации потенциальной нестабильности и исламистской угрозы.

This article is devoted to the study of the influence of the Islamic factor on the relationship between the Kyrgyz Republic and the Russian Federation at the beginning of the XXI century. The authors focus on the desire of the two states to ensure security, counter terrorism, extremism and further disseminate radical ideas. The invasion of the Islamic Movement of Uzbekistan on the territory of the Kyrgyz Republic was a strong impetus for further close cooperation between the two states and was reflected in the signing of the Declaration on Eternal Friendship, Alliance and Partnership. The founding of the Collective Security Treaty Organization and subsequent Agreements on the status and conditions of stay of the Russian air base on the territory of Kyrgyzstan also began to contribute to maintaining security. Despite the unconstitutional change of power in the Kyrgyz Republic in 2005 and 2010, and as a result, a sharp increase in the activity of religious organizations, Russia is beginning to make decisions to improve the activities of the CSTO and create a unifi ed Russian base in Kyrgyzstan, which suggests interest in liquidation potential instability and the Islamist threat.

Published: July 2024

The increasing water demand due to population growth and territorial expansion has significantly outpaced the natural water supply in Sungai Pinyuh, Kalimantan Barat. This sub-district, part of the Mempawah Regency, faces challenges such as insufficient access to clean water, deteriorating pipe infrastructure, and environmental pollution affecting water quality. To address these issues, a study has been undertaken to plan a comprehensive development of the drinking water distribution system in Sungai Pinyuh, guided by the Regional Regulation of Mempawah Regency No. 3 of 2014. The planning utilizes EPANET software, a tool developed by the U.S. Environmental Protection Agency (EPA), which allows for the simulation of dynamic conditions in the water distribution system. EPANET helps create detailed maps of the pipe network, determine pump and reservoir locations, and specify pipe characteristics. The software’s ability to simulate various scenarios, such as changes in demand or disruptions, is crucial for ensuring a reliable water supply. The analysis incorporates primary data from field observations and secondary data from population statistics and existing water supply documents. The proposed distribution system will employ HDPE pipes of various diameters and a pump with a capacity of 200 L/s and a head of 5 meters. Simulation results indicate that the system's velocity, ranging from 0.3 to 0.72 m/s, and other parameters, such as head loss and pressure, are within acceptable limits. Additionally, reservoir capacity planning is based on the maximum daily water demand, with a calculated capacity of approximately 3,347.839 m³ to ensure adequate supply. This study provides a strategic framework for improving the drinking water distribution system, addressing current deficiencies, and preparing for future needs.
