Estatalidad y gobernanza en los conflictos cupríferos de la transición energética
Authors: Hincapié Jiménez Sandra Miled
Published: December 2024

Este artículo analiza comparativamente mecanismos de gobernanza utilizados para gestionar conflictos relacionados con proyectos de extracción de cobre en Estados Unidos, Perú y México. Se argumenta que diferencias en los arreglos institucionales entre los tres países producen distintos tipos de gobernanza: delegativa a actores empresariales en Perú, regulada por agencias administrativas en Estados Unidos y centralizada en el gobierno federal en México. En el contexto actual de disputas geopolíticas vinculadas a la explotación de recursos naturales y a la creciente demanda de cobre para la transición energética, el artículo muestra cómo la distribución de competencias y recursos entre agencias gubernamentales moldea la capacidad estatal para mediar conflictos socioambientales, regular la apropiación de recursos y establecer equilibrios distributivos entre actores empresariales globales y comunidades locales. El análisis subraya la importancia de examinar tanto las reglas formales como la manera en que distintos actores las interpretan y movilizan, para comprender los efectos distributivos y de justicia ambiental de los proyectos extractivos.

Published: December 2024

La pandemia del COVID-19 transformó radicalmente la educación, generando desafíos para estudiantes y profesores ante la modalidad a distancia. Los educadores adoptaron métodos digitales, especialmente el "e-learning", como solución eficaz. Sin embargo, se evidenció la necesidad de regulaciones para una transición generacional exitosa. Este estudio se centró en la experiencia de estudiantes universitarios durante la pandemia, utilizando una encuesta virtual. De los 840 participantes, mayormente mexicanos, el 72.3% provenía de universidades públicas, y el 46.3% estaba en los dos primeros años de carrera, con un promedio de edad de 28.97 años. La mayoría dedicó entre 2 y 5 horas al día a las clases en línea. A pesar de desafíos como la calidad de internet, el 47.1% expresó estar "muy satisfecho" o "satisfecho". Las dificultades variaron según la carrera, siendo más notorias en áreas médico-biológicas. Los estudiantes, en general, elogian la enseñanza virtual, pero expresan preocupación por la falta de adquisición de habilidades clínicas y técnicas. En resumen, la diversidad de carreras presenta desafíos particulares, destacando la necesidad de enriquecer la experiencia de áreas médico-biológicas.

Legal Problems and Agamben‘s State of Emergency‖ in Post-February Russia: Methodological Analysis
Authors: KUKSA Tatiana , FEDOSOVA Ksenia
Published: December 2024

This article presents document flow in the context of the “state of exception” (according to Giorgio Agamben), which abolishes the effect of the usual legal distinctions, when, for example, “it is impossible to draw a line between peace and war”. As a scientific contribution, the authors deepen the binary/bipolar dimension of complaints/denunciations to a plural and bureaucratic dimension and explore them from a plurality of perspectives: user, legislative and law enforcement.The statistics indicates that the vast majority of investigations are related to the anti-war Internet activity of the defendants, for registration and evidence of which predominantly automated search systems and screen-work by law enforcement bureaucrats are used, rather than a written or oral flow of grassroots/spontaneous complaints/denunciations. Research shows the diversity of government agencies/bodies involved and interdepartmental competition for quick quantitative results (the ratio of cases filed and sentences), as well as Agamben’s abolition of customary legal distinctions.
The Synthetic Nature of the Armenian Medieval Philosophy in the Context of the Development of National Identity
Authors: SARGSYAN Hovhannes
Published: December 2024

The Armenian philosophy is a significant part of the medieval Armenian spiritual culture. During the long centuries without statehood, spiritual culture resources became decisive in preserving, reproducing and developing the Armenian identity. Based on the fact that the main institution, responsible for implementing this project, has been the Armenian Church, we refer to this model of the Armenian nation, formed in the early Middle Ages, as a model of a cultural-confessional nation. The Armenian spiritual culture, in general, and the Armenian philosophy, in particular, are characterized by their synthetic nature. Some elements of philosophical synthesis can be found in the patristic philosophy of Eznik of Kolb. The philosophy of David the Invincible is a brilliant manifestation of universal synthesis, too. AnaniaShirakatsi’s natural philosophy represents a synthesis of ancient scientific-philosophical concepts and the Christian worldview. The Armenian medieval education system also has a synthetic character.
Limitations of Classical Logic and Capabilities of Non-Classical Systems from the Point of View of Artificial Intelligence Development
Authors: HOVHANNISYAN Hovhannes O.
Published: December 2024

The article analyzes the differences between classical and non-classical logical concepts. The features and possibilities of transformational logic are considered. Specific details and proposals are analyzed, including using the example of the functioning of ChatGPT, where the use of transformational logic tools, namely rules that clarify the meaning of explicit forms of thought and derive new judgments from explicit forms of thought, as well as complex rules with the help of which it is possible to simultaneously solve the two problems mentioned, would significantly expand the possibilities and improve the operation of artificial intelligence (AI) systems.
Non-classical logical systems, partly critical of classical logic systems, not only open up new prospects for studying thought structures, but also consider issues that go beyond the subject area of classical logical systems, adding the possibilities of logical science.
In terms of interpreting the phenomenon of complementarity of logical concepts, the conception of polylogic by G. Brutian is valuable and the application of his ideas will give positive results from the point of view of further development of artificial intelligence tools.
Contribution of Fair and Equitable Treatment to the protection of renewable energy investments
Authors: Qian Xuming , Ghaziani Mohammad Akefi
Published: December 2024

With the increasing climate change crisis, the ongoing global energy security challenges, and the prerequisites for the development of sustainable and affordable energy for all, the need for renewable energy resources has been highlighted as a global aim of mankind. However, the worldwide deployment of renewable energy calls for large-scale financial and technological contributions which many States cannot afford. This exacerbates the need for the promotion of foreign investments in this sector, and protecting them against various threats. International Investment Agreements (IIAs) offer several substantive protections that equally serve foreign investments in this sector. Fair and Equitable Treatment (FET) clauses are among these. This is a flexible standard of treatment whose boundaries are not clearly defined so far. Investment tribunals have diverse views of this standard. Against this background, this article asks: What are the prominent international renewable energy investment threats, and how can FET clauses better contribute to alleviating these concerns? Employing a qualitative method, it analyses the legal aspects and properties of FET and concludes that the growing security and regulatory threats have formed a sort of modern legitimate expectations on the part of renewable energy investors who expect host states to protect them against such threats. Hence, IIAs and tribunals need to uphold a definite and broadly applicable FET approach to bring more consistency and predictability to arbitral awards. This would help deter many unfavourable practices against investments in this sector.

Authors: Pančíková Kristína , Veselovský Ján , Gergelyová Viktória , Dávid Lóránt Dénes
Published: December 2024

The objective of this article is to examine the provision of temporary exhibitions and events by Slovak museums and galleries, and to highlight their significance in the context of selected performances of these cultural attractions in the tourism sector. The article employs a secondary data analysis of the Ministry of Culture of the Slovak Republic and annual reports from 105 museums and 10 galleries in 2017, as well as 99 museums and 15 galleries in 2022. Correlation and regression analyses were employed to assess the dependence of variables. The results of the analysis confirm a direct, moderate dependence between the number of temporary exhibitions and events and the total number of visitors in museums and galleries. Additionally, the examination demonstrated that the exhibited activity has not had a positive effect on the revenues of museums and galleries. However, with an increasing number of events, their revenues from their own activities grew. The average revenues from one event were found to be higher in museums than in galleries.
Українська «Коза» Та Польський «Коник» У Різдвяно‑Новорічній Обрядовості Західного Полісся (Реконструкція Утраченої Традиції)
Authors: Davydyuk Viktor
Published: December 2024

The article raises the issue of the manifestation and subsequent existence of the New Year ritual of “walking with a horse” and its coexistence with the traditional “goat guiding” in Western Polissia. The character composition of both group members (“kozari” and “shuhatnyky”) has been established. Accordingly, considered have been the role functions of each character, as well as its localization within the region. Based on an analysis of verbal texts from the archived manuscripts of the Institute of Social and Cultural Anthropology, it has been stated that a symbiosis of Ukrainian and Polish elements of both rituals and their verbal accompaniment was formed in the 1920s‑30s within the Polish colonies of Western Polissia. The new rite of “walking with a costumed ‘horse’” began to displace the traditional one – “goat guiding”, attracting its traditional characters to its accompaniment. The article’s novelty lies in an assumption as to the common formative range of the western Polesian version of the New Year “walking with a horse” ritual in Central Europe, here based upon Ukrainian, Romanian, and Polish national traditions.
Літературна Біографія «Homo Politicus»: Хто Олеся Досвітнього – Агітка Анни Боярської
Authors: Skoryna Lyudmyla
Published: December 2024

The article analyses the literary modelling patterns of “homo politicus” biography in the novels Who by Oles Dosvitnii and Propaganda by Anna Bojarska. The concept system of both works being traditional for a political novel. At the centre of the novel are fictional characters: Nero, Liia, Leo (Who), Krzysztof Palivoda, Monika Weber, Conchita Estravados, Michel Bernard, Rolf Sperling (Propaganda). On the margins of the concept are “key characters” who have historical prototypes: Niiev, Rezhos, Netkhleb, Pavianore, Kutsenkyi, Struskyi (Who), A. Baader, U. Meinhof, G. Ensslin, J.‑C. Raspe, H. Paul, I. Schubert, P. Estravados (Propaganda). In modelling the inner world of “homo politicus”, Oles Dosvitnii is primarily limited to their political activities (the exception being the family story of Leo and Liia), on the other hand, Anna Bojarska is interested not only in politics, but also in the intimate and family life, and various spheres of character self‑realization (social, professional, creative). In their novels, the Ukrainian novelist and the Polish writer represent different types of “homo politicus” and we observe different versions of human destiny. These people mainly entered politics under the influence of a youthful idealistic desire to change the world. Further literary biography of “homo politicus” unfolds as the realization of a fabulous “three ways” matrix: 1) total disappointment and the ceasing of active political activity (David Sinclair in Propaganda); 2) political struggle, efforts to remain unblemished, being true to revolutionary ideals (Nero, Liia, Leo in the novel Who, Pablo Estravados, Monica Weber, Martha Dougherty – in Propaganda); 3) conscious cooperation (Michel Bernard, Rolf Sperling in Propaganda) or forced cooperation (Hans in the novel Who, Krzysztof Palivoda, Conchita Estravados, Hana – in Propaganda) with the special services, becoming a marionette in the hands of big political players. Actually, Anna Bojarska goes further than Oles Dosvitnii in understanding the ethical aspects of politics, in modelling the inner world of “homo politicus”. In the mid 1920s, the Ukrainian writer introduced an artistic reflexion of the mentality of “homo politicus” as a member of the left movement, while Anna Bojarska was to develop and deepen this in the early 1980s, as demonstrated by the economic and political consequences of left ideology dominance (totalitarian‑Bolshevik) in Poland, depicted through the rebirth of “new left” trends in Western Europe, and the transformation of the revolutionary movement into a puppet theatre, “ping‑pong of spies”.

Physiotherapist Communication Skills Questionnaire (Polish Version): A New Scale for Assessing the Communication Skills of Physiotherapists and Physiotherapy Students
Authors: Femiak Joanna , Guszkowska Monika , Czechowski Marcin
Published: December 2024

Objective: Optimal healthcare delivery relies on strong communication skills, which ideally are introduced in physiotherapy programs and honed with continuing vocational education. Existing general social skills tests do not have robust enough communication components to assess the communication skills of health professionals in clinical settings. The aim of the present study is to validate a newly created communicative skills questionnaire tailored to physiotherapists and physiotherapy students. Methods: In the first stage, 188 students aged 17–30 years (M=19.95; SD=1.510), including 80 males from the first (n=110) and second (n=78) years of undergraduate physiotherapy studies at Józef Piłsudski University of Physical Education in Warsaw (AWF), were included in the study to test reliability and determine the factor structure of the Physiotherapist Communication Skills Questionnaire being created (PCS-Q -17). In the second stage of the research, 109 physiotherapy students, including 47 males and 62 females aged 18–24 years (M=20.68; SD=1.471), were surveyed to determine test validity by establishing relationships with the results of questionnaires examining general social skills (the Social Competence Questionnaire, SCQ) and emotional intelligence (the Emotional Intelligence Questionnaire INTE).

Results: Based on the analysis of the communication process between the physiotherapist and the client, 17 statements were created describing behaviors that are a manifestation of communication skills in the therapeutic relationship. When assessing the reliability of items, two items with poor correlations with the overall score were removed. Based on the factor analysis using the principal component method with Varimax rotation and Kaiser normalization, three factors explaining 60.68% of the common variance were extracted. The final version of the PCS-Q contains 15 items with a five-point response format forming three scales: Management Skills, Assertiveness, and Relationship-Building Skills, with Cronbach alpha for the individual scales of 0.876, 0.808, and 0.739, respectively, and α = 0.908 for the whole tool. The validity of the scale was confirmed by the expected correlations with the SCQ and INTE scales.

Conclusion: The Polish version of the Physiotherapist Communication Skills Questionnaire (PCS-Q) was found to be a reliable and valid tool for measuring the communication skills with the patient in clinical situations revealed by physiotherapists and physiotherapy students. It allows for assessing patient management, assertiveness, and relationship-building. At the individual level, the PCS-Q can be used as a self-assessment scale, or it can be used corporately by external raters to estimate skills via observation.
The effect of cross-linking agent amount and type on the sorption properties of starch graft polyacrylamide and poly(acrylic acid) copolymers
Authors: Schmidt Beata , Wilpiszewska Katarzyna
Published: December 2024

In free radical polymerization initiated by 2,2’-azobis(2-methylpropionamidine) dihydrochloride, grafted starch copolymers with a weight ratio of acrylamide to acrylic acid of 1:2 were obtained. Three acrylic products were used to cross-linking starch copolymers: MBA, PETIA and EBECRYL 40 in amounts of: 0.2, 0.4, 0.6 and 1.0 wt.%. Materials were characterized by Fourier transform infrared spectroscopy, differential scanning calorimetry and reoviscometry. The sorption properties of starch copolymers were confirmed by sorption tests: water absorption, swelling in water and sorption of cations: trivalent iron and divalent copper. The highest water absorption is characteristic of materials cross-linked with MBA (1800%), then PETIA (1400%) and EBECRYL 40 (850%). On the other hand, the best swelling results are in the sequence PETIA > MBA > EBECRYL (1050% > 900% > 570%). The most effective sorbent of cations is the copolymer cross-linked with MBA. Solution purifications of 90% and 45% were obtained for Fe+3 and Cu+2, respectively.
Radial mixing in horizontal aerated tubular reactor
Authors: Prończuk Mateusz R.
Published: December 2024

The article discusses radial mixing in a Horizontal Aerated Tubular Reactor (HATR). The study aimed to experimentally investigate mixing in HATR by determining mixing time, liquid circulation time, and Peclet number values, which measure the ratio of advective to diffusive transport rates. The experimental setup included a transparent tube for observing fluid mixing and a color tracer was used for visualizing mixing. Mixing and circulation times were determined using non-intrusive optical method. The experimentally determined circulation time was in the range of 3÷6.5 s, and the mixing time was in the range of 5÷20 s. The results suggested that fluid flow structure in HATR was closer to plug flow rather than ideal mixing, as indicated by high Peclet numbers (20÷45).

Published: December 2024

In this study, chlorophenyl-substituted pyrazolone derivatives (5a–5c) were synthesized via the Baylis-Hillman acetate reaction. Comprehensive physicochemical characterization was conducted using 1H-NMR, FT-IR, and mass spectroscopy. Density Functional Theory (DFT) calculations at the B3LYP/6-31(G) level was employed to optimize molecular geometries and investigate electronic properties, revealing predominantly planar structures, with notable deviations in the pyrazole group. The HOMO and LUMO analyses showed π-delocalization across the entire molecule, with charge-transfer transitions dominating the excited states. Global Chemical Reactivity Descriptors (GCRD), including chemical potential, hardness, and electrophilicity index, were used to assess molecular stability and reactivity, indicating the molecules’ resistance to electron cloud deformation. Biological evaluations revealed exceptional antimicrobial and antifungal activities of the derivatives, with compound 5a demonstrating the highest efficacy against S. aureus, E. coli, A. niger and C. albicans. Furthermore, antiproliferative studies against HepG2 liver carcinoma cells showed that compound 5a exhibited superior anticancer activity (IC50 = 6 μg/mL), attributed to its structural features, such as chlorophenyl groups and a piperidin-4-one moiety. These moieties enhance the compound’s lipophilicity, facilitating cell membrane penetration and ROS generation, which contribute to apoptosis and inhibition of cancer cell growth. The findings suggest that chlorophenyl-pyrazolone derivatives, particularly 5a, hold promise as potent candidates for antimicrobial and anticancer therapies, paving the way for further pharmaceutical development.

Authors: Lejnieks Ilgmārs , Pelše Modrīte
Published: December 2024

The European Union’s Green Deal agenda emphasises the major importance of cleaner and more environmentally friendly energy sources for further economic development. Hydrogen is one of the potential renewable fuels that can replace fossil fuels in a variety of economic applications. The green hydrogen production across Europe is a key factor in achieving this goal. The aim of the study is to determine the influence of the connection between the availability of renewable energy sources, innovation, and economic development patterns on hydrogen production advancement. The research provides a comprehensive correlation analysis between the number of green hydrogen production sites and their capacity with statistical indicators describing economic growth, population, innovation, and particular economic characteristics within a particular EU Member State. The statistical data of this research outline the period from 2021 until the beginning of 2024. The results of the study suggest that nine of the 23 indicators examined – population size, gross domestic product, investment in research and development, total manufacturing value, overall industry value, total electricity produced, renewables in electricity production, solar power, and wind power in electricity production – have a strong or very strong positive correlation with hydrogen production. Furthermore, the analyses revealed that countries with large populations and high GDP volumes are more likely to develop hydrogen production in existing market circumstances.

Published: December 2024

Studies evaluating teenage knowledge, attitudes, experiences, and readiness for disasters in high-risk areas are scarce, nevertheless. Determine the elements that influence teenage readiness for disasters in an area with a high disaster risk index. 170 high school students in their eleventh grade participated in an anonymous online survey as part of a cross-sectional study design. Purposive sampling was used to choose the respondents. Surabaya was chosen as the study site because it has a high disaster risk index. The partial impact of knowledge, attitudes, experience, and disaster preparedness was determined using the t-test, and the R-Square. It was found that attitudes and prior experience regarding disaster preparedness had a partial influence. The partial test between experience and disaster preparedness and the partial test between attitude and disaster preparedness showed that teenagers in an area with a high disaster risk index had different attitudes and experiences when it came to being prepared for disasters. According to the report, high schools and the government should encourage regular training so that teenagers can get positive attitudes and more experience with disaster preparedness

Published: December 2024

Family interactions are needed in disasters because they play an important role in strengthening the emotional bonds between family members. In husband-wife interaction, different family roles and functions make couples feel complementary. This study aims to analyze the influence of socioeconomics, religiosity, and coping strategies on the interaction of husband and wife families of earthquake survivors in the Cianjur district. The study population was families of earthquake survivors in Cianjur Regency. The research sample was selected using a stratified non-proportional random sampling technique based on lightly damaged and heavily damaged houses. Respondents in the study were the wives of earthquake survivors in Cianjur Regency, with 200 respondents. Data processing and analysis used Microsoft Excel, Statistical Package for Social Science (SPSS) 25.0 for descriptive analysis, and Structural Equation Modeling-Partial Least Square (SEM-PLS) for influence analysis. The results showed high religiosity, spousal interaction involvement, and high satisfaction. Coping strategies, frequency of husband and wife interaction, and potential conflict between husband and wife are in the medium category. This study shows that husband and wife interaction is positively influenced by husband and wife's education, age of marriage, family income-expenses, and religiosity and negatively influenced by husband and wife's age. In addition, religiosity also has a positive effect on coping strategies. This study implies that families of disaster survivors are expected to increase family religiosity to improve husband and wife interactions. Local governments are advised to conduct adequate education for community readiness to face disasters.

Authors: Mu'arif* M Irvan , Ardiansah Ardiansah , Sri Budiastuti Maria Theresia , Utami Trisni
Published: December 2024

The increasing population in Bekasi Regency has led to higher demand for housing, vehicles, and industrial areas, resulting in carbon dioxide (CO2) emissions of approximately 8,148,642 tons per year, which negatively impact human health. Residential yards hold significant potential as green spaces that can be developed to enhance carbon absorption through vegetation. This research aims to analyze the role of society in utilizing residential yards to mitigate carbon emissions. The statistical analysis was conducted using the Chi-square test with a significance level of p-value 0.05. The results indicate that the success of planting vegetation in residential yards is significantly associated with age, gender, and education level. However, cultural factors do not show a significant relationship with yard utilization in Bekasi Regency. The most effective yard model for carbon absorption includes diverse vegetation types, particularly perennial plants, which can absorb a greater amount of carbon dioxide. A residential yard with a variety of fruit and perennial plants can absorb approximately 228 kg of CO2 per year for a housing area of 120 m²

Parijoto fruit (Medinilla speciosa Blume) is a plant known as a medicinal plant in Indonesia. Parijoto fruit production is still low. Phosphorous (P) fertilization can enhance fruit production, but the optimal dosage for parijoto has yet to be determined. The research objective was to obtain the P fertilizer dosage to improve the production of several parijoto accessions. The research was conducted from January to June 2023 at Agribusiness and Technology Park IPB. The study used a split-plot randomized complete block design with four replications. The main plot's accession factor consisted of Bogor, Kudus, and Nganjuk. The fertilizer dosage per polybag, as the subplot, consisted of without P2O5 (P0), 1.8 g P2O5 (P1), 3.6 g P2O5 (P2), 5.4 g P2O5 (P3), 7.2 g P2O5 (P4), 9.0 g P2O5 (P5). The results showed that applying P fertilizer at 7.2 g P2O5 produced the highest fruit weight per plant for the Bogor and Nganjuk accessions. For the Kudus accession, it was at a fertilization dosage of 5.4 grams of P2O5. There was an interaction between accession and P dosage on fruit weight per plant.

Apples (Malus sylvestris) have been grown in Indonesia, especially in highland areas such as Batu, Nongkojajar, and Poncokusumo. In order to propagate apple plants through in vitro, organ culture is performed in a controlled environment, free of pests and diseases. The research aimed to evaluate the effect of the composition of the growth regulator BAP-IAA on the growth and shoot multiplication of several apple cultivars in vitro. The research was carried out at the Indonesian Orchid Partners Laboratory Jl. Hasanudin 1 No 24 Junrejo District, Batu City, Indonesia. The four apple cultivars used were Fuji, Red Delicious, Gala, and Manalagi apples. Four types of growth regulator composition were the treatments: 3 mg L-1 BAP and 0.2 mg L-1 IAA, 6 mg L-1 BAP and 0.2 mg L-1 IAA, 3 mg L-1 BAP and 0.3 mg L-1 IAA, and 6 mg L-1 BAP and 0.3 mg L-1 IAA. The results showed that growth and yield were more precise in the combination of Red Delicious with the growth enhancer composition of 3 mg L-1 BAP and 0.3 mg L-1 IAA, as shown by the variable number of shoots and fresh weight of explants. The results showed that the combination of the Red Delicious apple cultivar with BAP 3 mg L-1+IAA 0.3 mg L-1 can be recommended as the best treatment in mass shoot production/multiplication.

In 2019, 7.9 million people with type 2 diabetes mellitus in Indonesia were undiagnosed diabetics (73.7%). One of the causes is the lack of diagnostic tools for type 2 diabetes mellitus in primary health care facilities in Indonesia. There are several methods for measuring HbA1c levels, one of which is the immunoassay method used at Sanglah Hospital, Denpasar. Another method that might be an alternative is the affinity chromatography method which is POCT (Point of Care Testing). This study aims to compare the results of HbA1c levels in patients with type 2 diabetes mellitus as measured using immunoassay and affinity chromatography methods. This research is an analytic study with a cross sectional design. The sample in this study consisted of 25 patients with type 2 diabetes mellitus who underwent HbA1c examination at Sanglah Hospital, Denpasar in the period 12 July 2021 to 1 October 2021 and met the inclusion criteria. The remaining blood samples after measuring HbA1c levels using the immunoassay method at Sanglah Hospital Denpasar were then taken to be measured by affinity chromatography method at the Kimia Farma Clinical Laboratory Denpasar. Statistical tests were carried out using the paired sample T-Test method. Paired sample T-Test result shows that the mean levels of HbA1c by immunoassay and affinity chromatography methods are not the same, with the mean difference 0,7760%, 95% CI 0,5058 to 1,0462%, p = 0 There is a significant difference in HbA1c levels in patients with type 2 diabetes mellitus as measured using immunoassay and affinity chromatography methods.

Blood pressure can increase because the walls of blood vessels become narrow and stiff due to the accumulation of cholesterol in the body. This study aims to determine the correlation between blood pressure and cholesterol levels in hypertension patients. This study was a cross-sectional study from secondary data on hypertension patients at the Kidney & Hypertension Polyclinic at RSUD Tabanan who met the inclusion and exclusion criteria. The minimum sample size required is 51 people. Of the 51 research subjects, 26 people (51%) were women and 25 people (49%) were men, 19 patients (37,25%) had grade 1 hypertension and 32 patients (62,75%) had grade 2 hypertension. Total cholesterol and LDL levels were found to be significantly higher in patients with grade 2 hypertension compared to grade 1 hypertension with p<0,05. Pearson correlation analysis showed a correlation between total cholesterol levels and systolic blood pressure (r=0.456, p=0,001), but no correlation was found between total cholesterol levels and diastolic blood pressure (r=0.036, p=0,804). Meanwhile, Spearman correlation analysis showed a correlation between LDL cholesterol levels and systolic (r=0.414, p=0,003) and diastolic (r=0.428, p=0,002) blood pressure. The results of this study show that total cholesterol levels with systolic blood pressure and LDL cholesterol with systolic and diastolic blood pressure have a positive correlation with moderate strength. However, further research is needed with prospective methods to obtain a direct relationship between cholesterol levels and blood pressure.

La disponibilidad y aprovechamiento del recurso hídrico actualmente es un problema que afecta el desarrollo de la vida y de actividades económicas. A pesar de que Ecuador es uno de los países con mayor disponibilidad de agua por habitante, el aumento de la demanda ejerce presión sobre las vertientes de abastecimiento. El presente estudio tuvo por objetivo determinar la escasez hídrica en la subcuenca del río Ambi, ubicada en la provincia de Imbabura en Ecuador, durante el periodo 1990-2017. Para ello, se determinó el índice de escasez hídrica (IEH) mediante el cálculo de la oferta y demanda hídrica usando los sistemas de información geográfica. La oferta hídrica se calculó con el uso del modelo hidrológico SWAT y los caudales simulados fueron validados con información recopilada desde el Instituto de Meteorología e Hidrología de Ecuador (INAMHI). Como resultados se obtuvo que durante el periodo 1990-2017, el valor promedio de la oferta hídrica fue de 4.94 m3/s y su demanda hídrica total fue de 17 m3/s. Esto demuestra que mientras la oferta disminuye, la demanda aumenta. Además, los valores obtenidos para el IEH se triplican desde el periodo 1990-1996 hasta el periodo 2007-2018 al pasar de 57.26 a 183.57 %. En consecuencia, los resultados evidencian la alta presión ejercida desde la demanda a la disponibilidad de recursos hídricos.

La calidad del agua superficial utilizada para la potabilización es de suma importancia debido a que de ella depende la funcionabilidad que puedan tener los procesos dentro de una planta de tratamiento. Una forma de monitorear los ríos han sido los índices de calidad de agua. La Parroquia Rural San Antonio del Cantón Chone, Provincia de Manabí, Ecuador, recibe el agua tratada por una planta modular que tiene su captación en el río Carrizal, es por ello que el presente artículo contempla el análisis del índice de calidad de agua en el sitio de captación como indicador de efectividad en el proceso de potabilización. En el río se establecieron tres puntos de muestreo y se evaluaron nueve parámetros de calidad en dos meses de temporada seca y dos meses de temporada lluviosa, a través de métodos gráficos y de ecuaciones, asimismo, la planta también fue monitoreada y comparada según la normativa vigente de calidad para agua potable. Los resultados del ICA-NSF en época de estiaje fueron 72.52 y 72.02, lo que refleja una calidad “Buena” y en época invernal 74.79 y 74.78, una calidad igualmente “Buena”, sin embargo, la turbidez se incrementa de verano a invierno en un 98.93 %. De igual manera, la planta potabilizadora tuvo una buena calidad en la mayoría de los parámetros. Estos datos permitieron establecer que la planta de tratamiento proporciona efectividad en el proceso de potabilización con el agua que recibe de la captación en todos los parámetros a excepción del cloro libre residual.
