Published: October 2023

La energía eólica ha alcanzado una capacidad mundial de 837 GW, y para poder seguir creciendo, se requiere seguir mejorando su eficiencia en la producción de energía, y reducir también sus costes de mantenimiento. El modelado de los aerogeneradores tanto en su propio diseño como en la implementación de sus sistemas de control es clave para maximizar la potencia generada y ahorrar costes operativos. Simuladores como OpenFAST permiten la parametrización de la turbina y el análisis de variables como la potencia generada o un estudio de las cargas a las que se somete el sistema. Debido a la complejidad de uso del simulador, para simplificar al usuario el manejo de este software se ha desarrollado una aplicación web que permite ejecutar un conjunto de simulaciones bajo OpenFAST. El programa se divide en dos partes: una parte que gestiona OpenFAST y que es manejada por Python; y la otra parte que funciona de interfaz al usuario y para la que se ha utilizado Vue. Se explican las principales características del software desarrollado y sus posibilidades de uso.
Regional Policy of the Russian Railways in THE Context of Depopulation. Geopolitical and Socio- Demographic Aspects
Authors: Ter-Akopov A. A. , Bezverbny V. A.
Published: October 2023

Railway transport have unique geopolitical and socio-economic importance for the Russian Federation, providing transport links between most regions, connecting the Asian and European parts with each other and some foreign countries, as well as holds together such a territorially large state as Russia in transport and socio-economic relation. In this regard, the problem of the development of transport systems in strategic regions of Russia, as well as the specifics of the regional policy of Russian Railways in the context of demographic problems and the geopolitical position of these territories, is becoming especially urgent. It is significant that the main connecting element of the infrastructure of the Asian part of the country is the rail transport. The research of the authors showed that the demographic and migration situation in the Russian regions is to a certain extent dependent on the density of the railway network. Then higher the density of railways, the more attractive regions in terms of migration are. And, on the contrary, in regions with a low density of railways, there is a steady trend of the migration outflow of the population. At the same time, demographic forecasts show that in the absence of promising infrastructure projects, negative trends in migration outflow and natural population decline are highly likely to continue, and, therefore, in the medium term, the population of the eastern regions will decline. In our opinion, for the effective spatial development of the territories of Siberia and the Far East, it is necessary to form a network of modern multimodal transport hubs and international transport corridors that take into account the climatic and demographic aspects of the development of the eastern territories of Russia. In addition, international competition for promising transport projects is constantly growing, which, given the low efficiency of the location of productive forces and the unused spatial potential of the Russian economy, becomes a significant geo-economic threat. The presented article examines the influence of the transport infrastructure level development for the system of settlement and trends in the socio-economic development of geostrategic territories of Russia; identified trends in the spatial and socio-economic development of the eastern territories located near the main railway lines; analyzed the demographic situation and migration trends in the eastern territories in the context of the personnel needs of the railway complex; strategic directions for the formation of personnel policy and replenishment of labor resources at Russian Railways have been developed. In addition, recommendations were developed to improve the efficiency of the spatial development of Siberia and the Far East based on the development of railway transport and promising projects for the formation of innovative transport systems.
Parsing China’s geostrategic designs in the post-war Afghanistan
Authors: Yao-Tian Fan , Li Wang
Published: October 2023

China boasts prolonged history of relations with Afghanistan. Throughout the 2010s, China has seen Afghanistan as a key part of what can be described the dynamically transnational “Belt-Road-Initiative”. Now with the Taliban takeover of the country, the question arises how China would be able to play a premier role in the post-war Afghanistan while trying to shun itself to be embroiled into the geopolitical mire as the superpowers did in history? The current study addresses two questions through an analytical-empirical approach to how China will realize its geostrategic design in Afghanistan. First, what are China’s objectives which are supposed to differ from those of the USSR and the USA? Second, why would China likely succeed in the country where the superpowers had failed before? Over the past decades, China has geared up its strategic ties with Russia, Pakistan, Iran, known as the Eurasian partners on the Afghan issue, and Central Asian states which are either the neighbors of Afghanistan or the member states of the SCO. Since Beijing endorses multilateralism and inclusive partnership in foreign affairs, it will unlikely act alone on the issue of Afghanistan. Rather, China is supposed to work on it through triple-level platforms–the Eurasian partners, SCO member states with border proximity of Afghanistan and the multilateral organizations such as the U.N. and the G-20–to fulfill its geostrategic designs in Afghanistan.
The “managed competition” concept in the US–China security nexus. Theoretical analysis and practical implementation
Authors: Shcherbunov V.
Published: October 2023

With the inauguration of President John Biden, the ideas of “managing” competition between the United States and China increasingly began to appear in the lexicon of American politicians and pundits. Most works on US-China competition emphasize its non-military aspects, which does not reflect the efforts that the US puts into competition in the military-political domain, as well as the importance of its regulation in preventing armed conflict between the two powers. This study seeks to solve a dual task: firstly, to identify the ideational content of the concept of "managed competition", and secondly, to analyze the existing formats of managing US-China military-political competition in the Asia-Pacific region in the 21st century. After analyzing the academic and analytical works of recent years, the author concludes that the concept of "managed competition" comprises three components: 1) regulation of competition through institutionalization in order to increase the predictability, strengthen crisis management mechanisms and reduce conflict potential, 2) anticipatory programming of the actions of international actors by creating incentives and deterrents for making foreign policy decisions, 3) describing the measures necessary to achieve success in competition (outcompeting). At a practical level, the management of competition in the military-political relations between the United States and China implies 1) the creation of international institutions to reduce the like-lihood of military incidents in the South China Sea and the Western Pacific, 2) setting the agenda in the Asia-Pacific region (the concept of the "Indo-Pacific region"), the consolidation and expansion of US military-political institutions (QUAD, AUKUS) with giving them the anti-Chinese focus, 3) US actions that impede the implementation of PRC’s military-political goals: reunification with Taiwan, control over the South China Sea, expansion of military-political contacts with the countries of the Asia-Pacific region.
NATO Development by the Early 2020s
Authors: Trunov Ph.
Published: October 2023

We can face the fact of huge military strengthening of NATO in the situation of the two confrontations. The first one is between the Euro-Atlantic community and Russian Federation, the second one is between the USA, the growing number of their partners and China. The article tries to explore the growing of NATO`s power, focusing on the case of its troops` groups, first of all multilateral. The methodical basis of the article is the theory of armed forces building. It perceives the armed forces as permanently evolving essence. The theory combines induction and deduction methods, can successfully answer the questions, which are difficult for some “big theories”, also in the situation when the predicting the world order is rather problematic. The author shows the evolution of multilateralism (from non-advanced to advanced) in the sphere of creation of common military groups by member states on the example of NATO. The change in the degree of European continental member countries "military machines" integration in NATO is presented as well as the perception of the tendency by the USA. In its activity the Alliance turns around 150 degrees. The new old key tasks are the deterrence of Russia and also containment of China. It means that the real challenges which are the risks of instability now are purely secondary tasks. The article covers the process of NATO Response Force (as the key element of power) strengthening, also the creation of Forward Presence Force in Eastern Europe. The scientific paper stresses that the decisions of Madrid summit (2022) are aimed at not only growing of NATO`s military potential, but also the ultimate integration of all types of military groups into a single whole. In this regard the factor of Russian special military operation in Ukraine has become the occasion, but not the reason of carefully planned and consistently implemented process of the return to the Alliance the role of the enormous collective power bearer for the Euro-Atlantic community.
Legitimizing Power Projection in the US Foreign Policy
Authors: Bogdanov A.
Published: October 2023

International relations (IR) scholars have traditionally viewed military alliances as vehicles, serving to ensure the states’ survival under anarchy and to maintain the balance of power essential for the systemic stability. At the same time, alliances that include a dominant state are often employed by the latter as the means of attaining its core objectives and the tools of legitimizing its extraordinary might and ambitious policies. Apparently, this situation favors ambiguity and uncertainty in terms of developing proper theoretical understanding of the nature of alliances as the core institutions, which pattern the states’ interactions, sustain international order, and ensure smooth functioning of the power relations. Seeking to elaborate more comprehensive approach to studying “asymmetric alliances” as the tools of both wielding the dominant state’s influence and legitimizing its preeminence, the paper engages the insights borrowed from the theory of structuration that helps overcome methodological limitations conditioned by dual understanding of “power” as either “attribute” or “relationship”. Specifically, the paper examines the United States’ “asymmetric alliances” in Europe and East Asia as distinct social structures, comprised of “resources” and “rules” that sustain practices of U.S. engagement in regional affairs so as to ensure reproduction of inequitable relationships between the allies and to legitimize the United States’ hegemony. This approach allows to reach more integrative understanding of the role of these alliances as the tools of Washington’s influence and the means of reproduction of the inequitable relationships between the allies, as well as to identify contradictions inherent in these hierarchical arrangements, engendered by growing tension between “resources” and “rules” involved in the process of wielding and legitimizing the “American power”.
Debate around U.S. Foreign Trade Legislation as an Element of Détente in Soviet-American Relations (1969–1979)
Authors: Yungblyud V. , Ilyin D.
Published: October 2023

Détente in Soviet-American relations throughout the 1970s was a complex and multifaceted process. The interaction of the two states as regards foreign trade, technology transfer and scientific exchanges was an important part of it. On the one hand, according to some détente ideologists, a critical mass of commercial ties along with scientific and technological projects established in accordance with the tenets of equality and mutual benefit could have created conditions for overcoming the Cold War and maintaining peaceful coexistence in the foreseeable future. At the same time, it was in the sphere of foreign trade that sharp disagreements first manifested themselves, indicating a clear-cut rift between the external political goals of the superpowers and the ability of their internal legislative systems to address these challenges. This article is devoted to reviewing the processes of transforming US foreign trade legislation during the détente period. It aims to insert this track into the pattern of forming Washington's course towards the Soviet state from the late 1960s to 1979. The research draws on the documents of both chambers of Congress, revealing the content of the debate on the adoption of export regulation laws and reflecting the views on this issue that existed at that time. The digital documents of the US State Department and Presidents R. Nixon and J. Carter are used to reflect their attitude vis-à-vis trade matters. It is shown how the executive and legislative branches interacted when updating the regulatory framework of foreign trade. The conclusion holds that while maintaining the general liberal vector in drafting foreign trade laws, they have always contained control standards for high-tech products export to socialist countries aimed at curbing scientific and technological progress in the USSR. As a result, the economic, scientific and technical foundation of détente in Soviet-American relations remained feeble and proved inadequate for preventing the confrontational recession in the early 1980s.

Authors: Nicolas Soza Exequiel , Domingo Depaula Pablo
Published: October 2023

Introduction: Given that psychosocial risks may be sources of stress at work and also encourage the presence of burnout, members of state security services are likely to present high levels of this syndrome. Objectives: To describe the prevalence and relationship between burnout and unhealthy habits amongst workers of the Argentine Federal Prison Service (SPF). Material and method: An ex post-facto study was carried out with descriptive, cross-sectional, comparative and comparative analyses. We used the Spanish adaptations of the Maslach Burnout Inventory MBI-HSS (Maslach and Jackson, 1986), the Test For Nicotine Dependence (Fagerström, 1978) and the Body Mass Index in 151 prison officers (88 men and 63 women of 22 to 52 years). Results: The prevalence of burnout was 6.62%, while the results for dimensions were: smoking 37.09%, passive smoking 70.20%, overweight 45.03% and obesity 44.37%. The dimensions of burnout showed that differences between groups indicate a higher level of emotional exhaustion in treatment and treatment functions, passive smokers and those who consume less fruit and vegetables on a weekly basis. There was greater depersonalization in subjects that are currently smoking. There was lower personal fulfillment in obese people, passive smokers, current smokers, moderate level smokers, those who consume less fruit and vegetables every week and those with obesity. Discussion: Smoking and high body mass index and links with eating habits are factors that may negatively affect the health and wellbeing of prison officers in terms of personal accomplishment.

Authors: DILAWAR Mohammed , QAYOUM Adnan
Published: October 2023

The energy crisis, Greenhouse Gas (GHG) emissions, and Chlorofluorocarbon (CFC) emis-sions are major environmental issues at present. It is critical to achieve and reduce emissions and energy consumption through the use of environmentally friendly refrigerants. Utilizing an environmentally friendly refrigerant such as HFC-32 may offer a viable solution to the ozone depletion potential (ODP) and global warming issues. This study examines the effects of aluminium oxide (Al2O3) nanoparticles at volume concentrations of 0.06, 0.08, 0.1, 0.12,
and 0.14% in pure refrigerants such as HFC-32 and R-410a used in air-conditioning systems based on the vapour compression refrigeration cycle. The thermophysical properties of pure and nanorefrigerants have been determined using REFPROP (NIST properties of fluid Refer-ence) and a theoretical formulation model using MATLAB software. The important outcomes of HFC-32 nanorefrigerant show the maximum performance with 0.14% alumina nano addi-tives which results in a 46.14% increase in the coefficient of performance (COP) and massive power savings upto 31.59%. Thermal conductivity exhibited an increase with an increment in nanoparticle concentration. Maximum thermal conductivity of 0.172 W/m-K is recorded
in the case of HFC-32/Al2O3 nanorefrigerant with 0.14% volume concentration. The net re-frigeration effect of pure refrigerants (R410a and HFC-32) is 77% and 79% and on addition of nanorefrigerants to the pure the net refrigeration effect increases to 81.2% and 83.5% for R410a and HFC-32 respectively.
Investigation of thermo-rheological properties of Fe3O4/Ethylene glycol nanofluid in a square cavity
Authors: KAMRAN Mohammad , QAYOUM Adnan
Published: October 2023

Many fluids used in heat transfer and transport phenomena restrict the effectiveness of heat exchange equipment on account of their low thermal conductivity. Using nanofluids, the ef-fectiveness of heat exchange equipment is enhanced by many folds. The use of magnetic nano-fluids for heat transfer generates a prospect of regulating flow and controlling the thermal and transport properties particularly the thermal conductivity and viscosity using an externally applied magnetic field. The present study involves synthesis of oleic acid-coated magnetic nanofluids at varying concentrations of 0 to 0.643% by volume, measurement of thermal conductivity, rheological properties and corresponding numerical simulation of Nanofluid in a heated square cavity. The thermal conductivity measurement have been carried out by transient hot-wire method using KD2-pro at varying concentrations of solid phase. The re-sults show a significant increase in thermal conductivity with increase in particle concentra-tion. Rheological measurements show variation in viscosity with shear rate, temperature and concentration. Moreover, it has been found that at low particle loading magnetic nanofluids exhibited Newtonian behavior unlike non-Newtonian behavior at increased concentration. Numerical simulation of the magnetic nanofluid in the heated square cavity demonstrates the immense potential of augmentation of heat transfer coefficient using such fluids.

Authors: K Geetha
Published: October 2023

Nonvenereal dermatoses of female external genitalia are genital diseases that are not transferred sexually and have a variety of etiologies. A prospective, observational study of adult female patients with nonvenereal dermatoses was conducted. A complete history and dermatological examination were performed, with skin biopsy in a few cases to aid in diagnosis. The data was collected and analyzed. During the course of this study, 82 cases of nonvenereal genital dermatoses were encountered. This study found that the most common age group was 20 to 45 years old [56%]. The most common presenting complaint was itching. In 42% of instances, fungal infections such as tinea cruris, vulval candidiasis, and scabies were identified. Lichen sclerosus et atrophicus, lichen simplex chronicus, contact dermatitis, vitiligo, psoriasis, seborrheic keratosis, and pemphigus vulgaris are among the other dermatoses identified. The Finlay dermatological life quality index (DLQI) questionnaire was used to assess the influence on patients' quality of life. Inflammatory illnesses such as lichen simplex chronicus lichen sclerosus et atrophicus, pemphigus vulgaris, psoriasis, hidradenitis suppurativa, and vitiligo reduced their quality of life moderately to severely.

Published: October 2023

Bronchiectasis is a common but neglected chronic lung disease. There is paucity of data from Southern India regarding the clinical, radiological and microbiological profile of patients with bronchiectasis.

To study the clinical profile, radiological pattern and microbiological flora in patients with bronchiectasis in a tertiary care center in South Kerala. A descriptive cross-sectional study done in 41 patients over 1 year.

This study comprised 41 patients, of whom 18 were males (44%) and 23 were females (56.1 %), with a predominant population pertaining to 61-70 years (51.2%). Majority were non-smokers (65%, N=27). Most common cause was post-TB bronchiectasis (34%, N=14). Predominant symptoms were cough (73.2%, N=30) and sputum production (70.7%, N=29), predominant clinical sign was crepitation (73.1%, N=30). Majority had PFT showing obstruction (60.97%, N=25), among which 48% (N=12) had severe obstruction. Radiologically, most common CT pattern was cystic bronchiectasis (46.3%, N=19), predominantly located in lower lobes (63.4%, N=26) with bilateral involvement (65.9%, N=27).  was the most frequently isolated organism (43.9%, N=18) followed by (29.3, N=12).

Most of our patients were females and post TB bronchiectasis was the leading cause of bronchiectasis. Cough and sputum production were the most common symptoms. was the commonest pathogen isolated from sputum samples. Spirometry showed obstructive pattern in majority of patients and cystic bronchiectasis being most common radiological pattern.
Prevalence of hypersensitive pneumonitis specific IgG antibodies in the Indian population: A retrospective study

Published: October 2023

Identifying the underlying antigen responsible for Hypersensitivity Pneumonitis (HP) in patients poses a significant challenge within the confines of a typical clinical environment. Our primary objective in this study was to investigate the distribution and prevalence of G antibodies among individuals diagnosed with HP, taking into account factors such as age, gender, and geographical location.

A retrospective study spanning 5 years (from January 2018 to June 2023) was conducted, involving patients over the age of 18 who had undergone screening for HP. Data collected from 1087 patients was analysed, and the patients were categorized based on age, gender, location, and their antibody status.

Out of the total cohort of 1087 patients, 62.47% were female, while 37.53% were male. The overall positivity rate for HP panel testing was determined to be 49.22%. Among the patients subjected to testing, 174 individuals (16.01%) tested positive for at least one specific antibody. Notably, among patients aged 18 to 30 years, Penicillium emerged as the most prevalent (48.28%), closely followed by fumigatus Fumigatus (44.83%). In contrast, for patients aged 31 to 45 years, Pigeon serum feathers exhibited the highest prevalence (39.69%). Moreover, the positivity rates varied across different regions in India.

HP can be attributed to an array of agents commonly encountered in both workplace and home settings, encompassing microorganisms, animal and plant proteins, as well as organic and inorganic chemicals. Discerning the causative antigen not only holds immense value for physicians in optimizing patient treatment but also plays a pivotal role in pinpointing the source of exposure. Armed with this knowledge, physicians can provide patients with tailored advice to minimize their exposure risk, potentially leading to disease stabilization or even reversal. In summary, the successful identification of the etiologic antigen emerges as a formidable tool for enhancing the overall quality of patient care.

Published: October 2023

Pulmonary tuberculosis (TB) and obstructive airway disease are of growing concern in a developing country akin to India. A considerable number of TB patients develop post-tubercular respiratory disease. There are few Indian studies assessing the relationship between antecedents of PTB and COPD. PTB has a considerable impact on quality of life.

To evaluate the prevalence of obstructive airway disease in previously treated pulmonary tuberculosis patients and to evaluate the impact of post TB obstructive airway disease on QOL using SGRQ-C.

A prospective, observational cross-sectional study was conducted in a tertiary care health centre over six months, enrolling 116 study subjects who met the inclusion criteria included after acquiring Informed consent. Study subjects had been categorized primarily based on prior history of PTB. Therefore, this study involved two groups of study subjects, PTB associated COPD and COPD. Subjects were assessed for PFT through the aid of MIR Spirobank smart App and QOL using SGRQ-C scale.

Of 116 patients, 19(22.6%) women and 65(77.4%) men and 5(15.6%) women and 27(84.4%) men were diagnosed as PTB associated COPD and COPD respectively. Dyspnea and cough with sputum were the most common symptoms presented by 76(94.04%) and 62(71.42%) patients respectively. The effect of airflow limitation (FEV1) was slightly increased in PTB associated COPD patients (25.65%) compared to COPD patients (26.4%) and study endpoint showed noteworthy decrease in QOL of PTB associated COPD(72%) patients compared to COPD(66.4%).

PTB-associated COPD constitutes a significant proportion of COPD within clinical setting. It is an independent risk factor for OAD in extensive TB burden countries. The results indicated that early diagnosis, appropriate management and control of TB are as critical as smoking cessation for reducing OAD. Early identification of Post tubercular COPD and early initiation of treatment in these patients improve the QOL and reduces morbidity and mortality.
Russia and Canada in the Arctic against the backdrop of the Ukraine crisis
Authors: Viakhireva Natalia
Published: October 2023

The article analyzes Russian-Canadian relations in the Arctic in the period from 2014 to 2022. Cooperation in the Arctic and the North was considered a priority area of Russian-Canadian relations in 2014-2021. However, it was repeatedly noted that despite the significant potential for interaction, there are risks due to growing negative trends in other spheres of bilateral relations and against the background of a general crisis in relations between Russia and the West. These concerns have met the reality.  In the period of the Russian Presidency of the Arctic Council (2021-2023), political changes beyond the Arctic agenda took place, and marked a turning point for the Arctic Council, international cooperation in the Arctic, Russian-Canadian relations in the region. Against the background of the deepening of the Ukrainian crisis, the Arctic Council has suspended its full-scale activities, many formats of multilateral cooperation with the participation of Russia were ceased. 
The results of previous years of investment and economic interaction between Russia and Canada were “cancelled”, the rethinking the security issues in the Arctic region is in process. These trends influence the future nature of Russia-Canada relations in the Arctic.

Economic Relations Between Canada and China in the Context of World Order Transformation
Authors: Khoroshilov Evgeny
Published: October 2023

In the context of unprecedented for the XXI century international tensions, Canadian-Chinese economic ties are currently at the critical point in their development. Official Ottawa continues to step up efforts to destroy them, actively participating in the anti-Chinese front being put together by the United States and regardless of the associated costs for its own economy. Chinese share of the Canadian foreign trade turnover is going down, while the deficit of Canada’s trade with China is growing markedly. Investment processes between the two countries have stalled. In 2019–2021, bilateral accumulated direct investments reached a plateau, demonstrating mixed dynamics. Various restrictions are being imposed on the activities of Chinese businesses in Canada. Further development of Canadian-Chinese economic relations, as well as dynamics and structure of bilateral trade and investment flows cannot but be affected by Canada's active participation in the American policy of strategic containment of China, especially in the field of ensuring access to strategic raw materials.

Mediante un estudio sistemático se caracterizaron los materiales arcillosos provenientes de la formación Amagá (Ts) y del Stock de Alta vista (Itagüí y Medellín) en el Departamento de Antioquia (Colombia). Ello permitió identificar las zonas con mejores calidades para el suministro de materias primas para la industria de cerámica roja en su área de influencia. Para cada zona se describen las características geológicas, y se determina la composición química y mineralógica; además, se desarrollaron pruebas específicas para establecer la aptitud cerámica de estos recursos naturales. Las muestras presentan contenidos de álcalis superiores al 0,2% lo cual podría bajar la calidad de los productos terminados.

Se realizó el aislamiento y caracterización de dos cepas bacterianas nativas productoras de exopolisacáridos (EPS). Con estas cepas se llevó a cabo la producción y análisis de la enzima implicada en la síntesis de EPS con el objeto de determinar la actividad enzimática. Las cepas fueron identificadas como Raoultella terrigena y Pseudomonas fluorescens. R. terrigena produce la enzima intracelularmente y por mecanismo de inducción; la enzima sintetizada por P. fluorescens es extracelular y de expresión constitutiva.

THE OPTIONS OF PLANT ORGANISMS FOR THE DEVELOPMENT OF NEW TYPES OR TYPOGENESIS IN PLANTS
Authors: Hagemann Wolfgang
Published: October 2023

The presented paper deals with the comparative morphological method (typology) combined with developmental studies as a means for understanding phylogenetic relations between different plant forms. This method becomes illuminated by two examples. The first are the phylogenetic relations between liverworts and ferns from which many follow the open repens-type. The second illuminates the much more complicated relationsbetween the primitive, tree-like angiosperms which returned via shrubs and herbal perennial plants to the delicate plants of the open repens-type. The angiospermic synflorescence-type plays a central role in this evolutionary pathway even if it becomes relinquished by the last step.

NONEMBEDDABILITY OF THE KLEIN BOTTLE IN RP 3 AND LAWSON’S CONJECTURE
Authors: Perdomo Oscar
Published: October 2023

In 1985 Montiel & Ros showed that the only minimal torus in S3 , for which the first eigenvalue of the Laplacian is 2, is the Clifford torus. Here, we will show first the nonexistence of an embedded Klein bottle in RP3 . Indeed we will prove that the only non orientable closed surfaces that can be embedded in RP3 are those with odd Euler characteristic. Later on, we will give another proof of Montiel & Ros’ result, assuming that the minimal torus has {x, –x} simmetry.

Published: October 2023

Introduction: Identifying the currently-used outcome measures for clients with cerebral palsy (CP) in the Iranian occupational therapy (OT) research can declare the new trend of such researchers and identify the more focused domains regarding such individuals. Accordingly, this integrative review aims to define the utilized outcome measures for school-age children with CP in the Iranian OT research.
Materials and Methods: We conducted an integrated review of online Persian and English databases, namely PubMed, Web of Science, Otseeker, Cochrane, Medline, Embase, CINAHL, PsycInfo, OVID Medline, Magiran, ISC, SID, IranMEDEX, Irandoc, and IRCT, along with the Google Scholar search engine from January 2000 to March 2021.
Results: Out of 605 potentially relevant articles that were initially retrieved, 51 articles met the inclusion criteria, and their used outcome measure(s) was identified. A total of 42 identified outcome measure(s) were not diagnosis-specific and or child-report. A maximum of 15 tools, which assessed the motor components of CP children based on a biomedical bottom-up approach, was commonly used by the majority of studies.
Conclusion: Most Iranian OT studies utilized bottom-up outcome measures. Iranian OT researchers were suggested to highlight the current paradigm of OT in their research regarding school-age children with CP to comprehensively address their multiple challenges and needs according to a top-down client-centered approach.
SEKULARISASI DAN SEKULARISME DI CHINA
Authors: Prihambodo Dimas
Published: October 2023

Para pakar sejarah sepakat bahwa sekularisasi di Eropa Barat telah terjadi sejak 250 tahun yang lalu. Seiring berjalannya waktu, sekularisasi telah dianggap sebagai krisis besar bagi Kristen dan dunia Barat. Di dunia Timur, khususnya dunia Islam sekularisasi sudah terjadi dibeberapa tempat. Hal tersebut terjadi setelah masa kolonialisasi negeri-negeri Islam oleh bangsa Eropa. Berdasarkan hal tersebut, penulis tertarik untuk meneliti sekularisasi yang terjadi di dunia Timur lainnya, yaitu China. Kesimpulan yang diperoleh adalah sekularisasi yang terjadi dapat dilihat dalam dua bentuk, yaitu peniadaan kesucian dan kewibawaan agama daripada politik (desacralization of politics) dan penghapusan kesucian dan kemutlakan nilai-nilai daripada kehidupan (deconsecration of values). Selain itu, paham Marxisme-Leninisme memberikan andil besar pada proses sekularisasi di China.

One of the phenomena of poverty that occurs in this community is in Barito Kuala which is one of the rice granaries in South Kalimantan, namely in Anjir Pasar Lama village, Anjir Pasar district. The role of parents with backgrounds in Anjir Pasar Lama Village in Islamic religious education can be done to ensure that children start from TKA/TPA Al Quran in Anjir Pasar Lama Village, take their children to the local Koran teacher and visit the Taklim assembly, even though have to travel quite a distance. Determination of data sources in this study is to use purposive sampling, namely: selected people who will be asked questions, and the questions according to the specific characteristics of the sample, purposively until the data collected is deemed sufficient. The family as one of the centers of education can be said to be still not maximized due to the feelings of parents who feel they are not 'worthy' or marginal. In addition, the intention of parents to send their children to a higher level tends to be non-existent. This is because parents are "realistic" with unsupportive economic conditions. However, for the religious education of farming families, it tends to be better in its application.
