Finally, he discusses global modernity and the need to reconsider its trajectory in light of communist experience.
Egy ritkábban használt survey-kísérleti elrendezés, az alanyokon belüli ismételt mérés egy nyelvészeti kutatás példáján
Authors: Németh Renáta
Published: June 2021

A társadalomtudományi felvételekben az utóbbi évtizedben tért hódított az erősebb oksági bizonyítékot szolgáltató kísérleti megközelítés. Népszerűségét még inkább növeli az online platformok elérhetőségéből fakadó könnyű kivitelezhetőség. Ugyanakkor az alanyok közötti (betweensubjects) elrendezés sokkal elterjedtebb, mint az alanyokon belüli (within-subjects), annak ellenére, hogy az utóbbi, bár nem mindig megvalósítható, olcsóbb és statisztikailag hatékonyabb. A tanulmány először röviden összeveti a két megközelítést, és összefoglalja a társadalomtudományi alkalmazhatóságukat, majd, mivel az alanyokon belüli elrendezés vizsgálata statisztikailag nem triviális, bemutatja az ahhoz illeszkedő többszintű keresztezett randomhatásmodell használatát egy hangszimbolikai kutatás példáján. Az elemzés során a szerző kitér az alanyokon belüli elrendezés potenciális gyengeségeinek, a külső, illetve a konstrukciós érvényesség korlátjainak vizsgálati lehetőségére is.

Espacios y emociones: una propuesta desde la ontología histórica
Authors: Zaragoza Bernal Juan Manuel
Published: June 2021

En este artículo proponemos una nueva aproximación al estudio de las emociones desde una aproximación transdisciplinar a la historia y a la filosofía. Para ello, cuestionamos lo que llamamos teoría del appraisal y apostamos por una definición social de las emociones, basada en la teoría de la emoción construida de Lisa Feldman Barrett. En concreto, proponemos considerar a las emociones como categorías humanas, lo que nos permitiría su estudio como parte de la ontología histórica. A partir de aquí, analizamos el problema acerca de la relación entre cultura material y experiencia emocional y proponemos el concepto de matriz, desarrollado por Ian Hacking, como una forma de ligar ambas. Apoyaremos esta aproximación con un estudio de caso: el del Hospital para Mujeres Incurables Jesús Nazareno, en Madrid, en la década de 1870. Este caso nos servirá para identificar y probar un conjunto de herramientas metodológicas que nos ayuden a analizar aquellos componentes materiales que construyen, determinan y condicionan nuestras experiencias emocionales.
Pedro Rimonte (1565-1627): análisis historiográfico
Authors: Esteve Roldán Eva
Published: June 2021

El estudio analiza las líneas de investigación que se reflejan en la amplia bibliografía sobre el músico Pedro Rimonte sin pretender realizar un examen exhaustivo de toda la producción existente. La cronología estudiada comprende desde las ediciones producidas a principios del siglo XVII hasta las últimas publicaciones realizadas en la actualidad, con la mención de más de cien volúmenes que incluyen información del compositor o su obra. El análisis divide la bibliografía examinada en cuatro etapas que se exponen por orden cronológico y se definen por los aspectos más relevantes con respecto al progreso de las investigaciones. El estudio de la evolución bibliográfica muestra la adaptación del contenido a algunas corrientes historiográficas e ideológicas imperantes en cada época y descubre la permanencia de algunos errores que todavía se mantienen en las publicaciones actuales.
La historia de las masculinidades en la España decimonónica: el surgimiento de un nuevo campo historiográfico
Authors: Blanco Rodríguez Elia
Published: June 2021

Este artículo aborda la historia de las masculinidades en la España contemporánea, un novedoso campo de estudio con una creciente vitalidad, prestando especial atención a la investigación centrada en el siglo XIX. En primer lugar, reflexiona sobre algunas de las principales herramientas metodológicas y conceptuales disponibles para su desarrollo. A continuación, examina la situación actual de los estudios e indica posibles caminos por los que transitar. Por último, analiza la práctica del duelo como vía privilegiada para explorar uno de los modelos de masculinidad que convivieron en el siglo XIX en España, la masculinidad normativa de las clases medias y altas. Los duelos permiten un acercamiento a esta identidad de género debido a que los debates y contradicciones que habitualmente suscitaban, reflejados en múltiples fuentes históricas, muestran las aspiraciones del momento respecto a los varones de las mencionadas capas sociales, aspiraciones que giraban en torno a la noción del honor.
Imagem informação
Authors: Freire Emerson
Published: June 2021

A renovação artística e as reflexões sociológicas e filosóficas provenientes da relação arte/tecnologia, a partir da Revolução Industrial, intensificam-se após a chamada virada cibernética. A imagem passa a ser prioritariamente imagem-informação, deixa de ser apenas imagem-representação. Assim, torna-se fundamental entender o funcionamento e fundamento da construção dessas imagens nos diversos setores da sociedade, incluindo as manifestações artísticas que tematizam ou se utilizam das tecnologias mais recentes. Todavia, esse entendimento não deveria contemplar um ponto de vista humano apenas, numa espécie de manifestação senhor-escravo em relação a essas tecnologias, mas incluir a perspectiva da máquina também, o que é bem mais difícil, pois, neste caso, é necessário compreender informação, sensação e percepção em sua articulação, em sua relação homem-máquina, não isoladamente. Afinal de contas,é o tripé informação-percepção-sensação, enquanto campo problemático dos mais diversos domínios sociais, que se relaciona com a invenção de algum modo. Dito de outra forma, as tecnologias contemporâneas obrigam a uma mudança no próprio conceito de máquina, consequentemente, também na compreensão cultural de sua função e das formas como o ser humano se relaciona com ela. O presente artigo pretende discutir essas questões por meio de obras selecionadas do cineasta Harun Farocki.

A hora e a vez do decolonialismo na arte brasileira
Authors: Paiva Alessandra Simões
Published: June 2021

Este trabalho propõe uma reflexão a respeito do conceito de “decolonialismo” e sua relação com as artes visuais no Brasil. A proposta é entender o impacto do crescimento exponencial da produção artística e teórica voltada para as questões de raça, etnia e gênero, e sua contribuição para a consolidação de uma teoria decolonial na arte brasileira. Apesar da ainda exígua representatividade no sistema artístico brasileiro, inclusive em seus espaços de decisão, pessoas negras, indígenas e que não se encaixam no sistema binário de gênero vêm produzindo uma significativa massa poética e teórica, revelando a urgente necessidade de reparação frente ao sistemático apagamento de suas experiências e memórias pela história da arte de matriz eurocêntrica e colonialista.
Antonio Bento e Romero Brest
Authors: Bedtcher Araceli Barros J.
Published: June 2021

O presente artigo analisa a produção crítica de dois expoentes do cenário cultural latino-americano do século XX: Antonio Bento e Romero Brest. Esses autores são contemporâneos entre si e amealharam importantes contribuições para a crítica de arte de seus respectivos países, Brasil e Argentina, na consolidação do abstracionismo.  Através de uma abordagem comparativa sobre ambos os críticos, destacaram-se as aproximações e diferenças nos seus discursos em um cenário de importantes transformações culturais: a fundação do MASP (1947) e a I Bienal de Artes (1951). Por fim, buscou-se evidenciar as contribuições de uma crítica de arte especializada no entendimento e promoção da arte abstrata como linguagem artística também válida para o Brasil e Argentina.
América Latina em contexto
Authors: Gonçalves Lisbeth Ruth Rebollo
Published: June 2021

O presente dossiê reúne textos que põem o foco em questões significativas para o estudo das artes visuais, especialmente pensando a realidade latino-americana. A proposta que lancei aos autores que interagiram comigo, no meu papel de orientadora ou supervisora, ao longo de suas carreiras, foi a de oferecer um artigo com tema de interesse aos estudos latino-americanos. Pensa-se, neste dossiê, o Brasil inserido no contexto da América Latina e mundial. Cada autor realiza uma reflexão no campo da produção ou circulação da arte e tem de modo explícito ou subentendido, como um dado inerente à sua análise, a questão da “decolonização” ou “descolonização”. Nos artigos, este ponto crucial aparece como uma episteme fundamental, direta ou indiretamente explícita. Seus textos partem de suas pesquisas recentes e muitos temas decorrem de estudos que realizaram para sua titulação universitária.  A arte indígena atual, a expressão popular no contexto da cultura, assim como as exposições e sua visitação e a prática da crítica de arte são temas presentes neste conjunto. Trata-se de um dossiê com textos apoiados em debates atuais. Isto quer dizer: encontramos leituras das experiências da arte, fundamentadas em discussões conceituais hoje presentes no campo das Ciências Humanas e nas Artes.

El español jurídico: propuesta de intervención en el aula de español con fines específicos
Authors: Sevilla-Vallejo Santiago , Sanz i Vilar Esther
Published: June 2021

Es bien sabido que para el correcto aprendizaje de una lengua, además de conocer las reglas gramaticales, el léxico y demás normas formales, también se debe conocer la cultura relacionada con la misma. La cuestión principal cuando se trata este asunto es qué cultura llevar al aula, pregunta que se acentúa cuando tratamos las lenguas de especialidad. El presente artículo trata de definir qué son las lenguas de especialidad en general y de presentar las características del español jurídico en concreto. Además, y en consonancia con lo mencionado anteriormente, también se trata la “cultura profesional”, es decir, los usos y costumbres que tienen los operadores jurídicos españoles en el ejercicio de su profesión.

Además de este enfoque teórico, también se plantea una propuesta de intervención, concretamente se trata de una unidad didáctica basada en un caso real de derecho penal. Esta propuesta incluye una serie de actividades variadas que tienen como objetivo trabajar contenidos gramaticales, léxicos, de tipología discursiva propios del español jurídico así como de la cultura profesional jurídica. Estos contenidos se presentan a través un caso real que acompaña al alumno desde el principio hasta el final de la unidad didáctica y del cual forma parte activamente, ya sea como acusación o como defensa.

Authors: Abiyasa Putri Izdihar Ramadhanty , Aswin R Haryanto , Yuliawati Tri Hartini
Published: June 2021

Background: Cigarrete smoke has been ascociated with many health-related problems especially in long time use. One of many health problems that are affected is the reproductive system that give negative impact in fertility. However, there are limited studies about this in acute exposure of cigarette smoke.
Objective: The aim of this study is to investigate the effect of acute exposure of cigarette smoke on endometrial thickness and number of ovarian follicles in rats.
Methods: Thirty adult female rats were randomly divided into 3 groups: P0, P1 and P2. The P1 and P2 groups were exposed to cigarette smoke for 15 days with dose of 2 and 4 cigarettes daily, respectively. Vaginal swab was done twice, before and after the last treatment, to determine the proestrus phase of the animals. Histological slide of uterus and ovarium using Haematoxylin Eosin staining were observed under light microscop. Number of ovarian follicles were measured, and the thickness of endometrium was meassured using CellSens software version 2.3 (Olympus Life Science). Statistical analysis of data was performed using MANOVA in SPSS software version 23 for Windows.  
Results: There were no significant differences in both endometrial thickness and number of ovarian follicles between 3 groups (p>0.05). However, we found that there were a downward trend of some variables (endometrial thickness, number of primary follicles, de Graff follicles, and corpus luteum) from P0 to P2.
Conclusion: We concluded that acute exposure of cigarette smoke not yet influenced the female reproductive organ, based on histological appearance of endemotrium and ovarium.

Published: June 2021

The prevalence of obesity has been increasing worldwide; however, the optimal dietary strategy for improving anthropometric and cardiometabolic parameters remains unknown. This review discusses the effectiveness of popular diets in the management of obesity and obesity-related comorbidities. The differences among popular diets are small and associated with dietary adherence and caloric intake. The Mediterranean diet is most effective in facilitating weight loss and improving cardiometabolic parameters, although the Central European diet seems to be a good alternative.
The Geometrized Vacuum Physics Based Onthe Algebra of Signature
Authors: Batanov-Gaukhman Mikhail
Published: June 2021

The aim of the article is to develop geometrized physics of a vacuum on the basis of two basic postulates: 1) the constancy of the speed of light (more precisely, the speed of propagation of electromagnetic waves) in the vacuum; 2) the ‘vacuum balance condition’ associated with the statement that only mutually opposite formations are born from the vacuum, so that, on average, they completely compensate of the manifestations of each other. The Algebra of signatures is proposed as a mathematical basis for geometrized physics of a vacuum.
Anti-cancer Immune Reaction and Lymph Node Macrophage; A Review from Human and Animal Studies
Authors: Komohara Yoshihiro , Anami Toshiki , Asano Kenichi , Fujiwara Yukio , Yatsuda Junji , Kamba Tomomi
Published: June 2021

Lymph nodes are secondary lymphoid organs that appear as bean-like nodules usually <1 cm in size, and they are localized throughout the body. Many antigen-presenting cells such as dendritic cells and macrophages reside in lymph nodes, where they mediate host defense responses against pathogens such as viruses and bacteria. In cancers, antigen-presenting cells induce cytotoxic T lymphocytes (CTLs) to react to cancer cell–derived antigens. Macrophages located in the lymph node sinus are of particular interest in relation to anti-cancer immune responses because many studies using both human specimens and animal models have suggested that lymph node macrophages play a key role in activating anti-cancer CTLs. The regulation of lymph node macrophages therefore represents a potentially promising novel approach in anti-cancer therapy.
Some Results for a Time Interval Approach to Field Theory and Gravitation
Authors: Hollestelle Harmen Henricus
Published: June 2021

This paper consists of two parts. In part I some new relations for a field theory with time intervals are derived. One concept of field theory evaluated is complementarity, another is operators however both defined within a time interval description. Part II includes specific results and commentary. Discussed are time interval dependent wave propagation surfaces for star source emission waves and derived is a metric surface area requirement for propagation surfaces. The results allow to consider one field that like gravitation within General Relativity applies to both non zero and zero mass. The associated field energy is space time dependent for non zero mass, and is related to a space time dependent metric tensor for zero mass wave particles. Defined is internal energy transfer where wave particle numbers increase linearly and mass and momentum diminish, decrease inversely with the distance from the wave emission source. The commentary are applications related to cosmological overall volume and temperature dependence.

Soybean is including a major protein source with a relatively higher consumption rate. Similarly, various efforts have been adopted towards boosting production, including selecting high-yield species and soil fertility improvement using fertilizers. This research aims to increase soybean production by employing the appropriate variety and phosphate fertilizers to improve soil fertility. This experiment was conducted in Takalar, South Sulawesi, between April-July 2019. The split-plot design method was applied with three replications. Consequently, the main plot encompasses the treatment of three varieties, termed Argomulyo, Anjasmoro and Gema, while the subplots relate to phosphate fertilization, comprising three levels, including fertilization with a dose of SP-36 at 50, 100 and 150 kg.ha-1. The results showed that the modifications in variety and phosphorus fertilization significantly influenced soybean production, as Argomulyo obtained the maximum rate of 2.77 t.ha-1, followed by Anjasmoro at 2.45 t.ha-1. Furthermore, phosphate fertilization with a dose of SP-36 at 100-150 kg.ha-1 demonstrated the optimal soybean production as indicated by the maximum productive nodes and pods. Therefore, no interaction was observed between the various species and phosphate fertilization.

Roots represent the fundamental structure and material transport systems in plants. These important organs are used to study the adaptation processes in the environment. During the nursery stage, root evaluation serves as determining the seedling quality before transplant. This research aims to ascertain the root characteristics of several Arabica coffee varieties for a suitably vigorous root nursery system. Kaliwining Experimental Garden, Jember, Indonesia, served as the research location. The method used was a completely randomized design with a single factor, including arabica coffee varieties (Abesinia-3, Andungsari-1, BLP-4, Gayo-1, K-08, K-29, K-34, K-79, K-130, Kartika-1, Kayumas and Sigararutang). The result showed that the differences in the various sample factors significantly influenced the root properties. In addition, the entire observation parameters demonstrated a positive correlation except for the root and shoot ratio. Furthermore, BLP-4 v obtained the maximum values for plant height, stem diameter, fresh dry weight of taproot, and root biomass, while Gayo-1 variety observed the greatest number of leaves. Also, the Sigararutang variety indicated the highest value of the fresh and dry weight of shoot, fresh weight of lateral roots, and root length, while Kayumas and K-34 varieties acquired the lowest values of plant height, fresh and dry weight of shoot and root, as well as root length. Therefore, BLP-4, Gayo-1, and Sigararutang varieties exhibited the potentials of broader adaptability.

Sloping topography, clay textures and improper fertilizer application create a high risk of surface runoff and nutrient loss. Phosphorus occurs as an important nutrient in coffee beans. The objective of this research is to analyze the effects of biopore infiltration hole with compost (BIHC) on the total and available phosphorus in robusta coffee in Bangelan plantation, Malang. A complete randomized block design with 4 replications was applied and the treatments consisted of control and BIHC. The BIHC process involved biopore hole depth of 30 and 60 cm for the goat manure and coffee pulp compost, respectively. Several parameters were also observed, including pH, total and available phosphorus as well as soil organic carbon (SOC) between 0-20, 20-40 and 40-60 cm in soil depth. Subsequently, the analysis of variance (ANOVA) and Duncan's Multiple Range Test (DMRT) were used to comprehend the data. The results showed the ability of BIHC to significantly increase the pH, SOC and total-P, compared to the control with less available-P. These total-P improvements up to 103.27, 108.73 and 132.09% were reported at soil depths between 0-20, 20-40 and 40-60 cm, respectively, while available-P were possibly enhanced up to 77.59, 28.27 and 151.99% at corresponding depth ranges.

Published: June 2021

Tribulus terrestris is conventionally propagated using seeds but has limited germination capacity. One approach that can be done for this plant multiplication is in vitro tissue culture. This study was conducted to determine the growth potential of T. terrestris in vitro by the addition of auxin (IAA) and cytokinin (BAP) as growth regulators at several concentrations. The study was conducted at the Laboratory of Plant Physiology and Biotechnology, Faculty of Agriculture, Universitas Sebelas Maret Surakarta from February to December 2017. The experiment employed factorial Completely Randomized Design (CRD) method with 2 factors, namely IAA concentration (0 ppm, 0.1 ppm, 0.2 ppm, 0.3 ppm), and BAP concentration (0 ppm, 0.3 ppm, 0.5 ppm, 0.7 ppm). The observed growth parameters were shoot emergence time, leaf emergence time, root emergence time, number of leaves, and number of roots. Data were analyzed using analysis of variance followed by DMRT with a 95% confidence level. The results showed that the addition of IAA only affects leaf emergence time, while the addition of BAP had a significant effect on the leaf emergence time and number of leaves. The interactions between IAA and BAP had a significant effect on leaf emergence time.

Published: June 2021

The purpose of this study was to investigate within- and between-threshold parameter invariance for items of a fourteen-item Positive Affect Scale developed to assess positive moods (like happy, peaceful, etc.) of university students. To test whether the estimated threshold parameters were as expected (1 to 5, with increments of 1) across all the 14 items, Graded Response, Partial Credit, and Rating Scale Models were fit the response data collected from 326 students. A comparison of the model fit statistics, such as the negative 2log likelihood and chi-square values, revealed that the Graded Response Model had the best fit and that the thresholds estimates for all the items in the Positive Affective Scale were reasonably close to the expected 1 to 5 values with increments of 1. The study illustrates how polytomous response models can be used to test the psychometric quality of items with ordinal rating scales.

Background: The patients on mechanical ventilation were always critically ill and ventilation may cause injury and inflammatory disorders in the lungs of such patients. We sought to determine whether statin treatment has a protective effect on the outcome of the ventilated patients. Methods: A retrospective observational study of mechanically ventilated patients from the Medical Information Mart for Intensive Care III (MIMIC-III) database. To ensure the robustness of the findings, we utilized the gradient boosted model, propensity score analysis, doubly robust estimation and an inverse probability‐weighting model in the statistical procedure. The propensity score of statin use was calculated by age, sex, severity scores and 32 other variables. Results: Compared with nonusers, the use of statins was associated with improved 28-day survival in the unmatched cohort (HR 0.85 95% CI 0.80~0.90) and matched cohort (HR 0.79 95% CI 0.73~0.85). Statin use was also associated with improved 60-day (HR 0.81 95%CI 0.75~0.85), 90-day (HR 0.81 95%CI 0.76~0.86) and in-hospital (HR 0.81 95%CI 0.76~0.86) survival in the matched cohort. Statins use was associated with longer ventilator free days (VFD28, 14.93±13.11 vs 12.06±13.26) and longer ICU free days (13.41±12.14 vs 10.86 ±12.19) in the matched cohort. Different types of statins were associated with improved 28-day survival. The subgroup analyses results showed improved 28-day survival in most subgroups, but this improvement was not observed in patients with pneumonia, septicemia or acute respiratory failure. Conclusions: In a population of mechanically ventilated patients, the use of statins may be associated with reduced mortality. This protective effect was observed only in mild-to-moderate patients instead of critical inflammatory ones.Trial registration: http://www.chictr.org.cn/index.aspx; Registration number: ChiCTR2000029594
Search-in-forest optimizer: A bio-inspired meta-heuristic algorithm for global optimization problems

Published: June 2021

The present research proposes a new particle swarm optimization-based metaheuristic algorithm entitled “search in forest (SIF) optimizer” to solve the global optimization problems. The algorithm is designed based on the organized behavior of search teams looking for missing persons in a forest. According to SIF optimizer, a number of teams each including several experts in the search field spread out across the forest and gradually move in the same direction by finding clues from the target until they find the missing person. This search structure was designed in a mathematical structure in the form of intra-group search operators and transferring the expert member to the top team. In addition, the efficiency of the algorithm was assessed by comparing the results to the standard representations and a problem with the genetic, grey wolf, salp swarm, and ant lion optimizers. According to the results, the proposed algorithm was efficient for solving many numerical representations, compared to the other algorithms.

Purpose: Despite follicular lymphoma (FL) is frequently characterized by a moderate increase of glucose metabolism, PET/CT examinations provides valuable information for staging and response assessment of the disease. The aim of the study was to assess and compare the diagnostic performance of PET/ldCT and PET/ceCT, respectively, in evaluating FL patients at the end of treatment. Methods: Fifty FL consecutive patients who underwent end-of-therapy PET/CT with both ldCT and ceCT were analyzed. Two blinded observers independently assessed PET/ldCT and PET/ceCT applying the Deauville score (DS) and Lugano classification criteria. PET imaging obtained after the end-of-treatment (EoT) was classified as showing PET and ce-CT matched response (concordant imaging group, CIG) or PET and ce-CT unmatched response (discordant imaging group, DIG). Relapse rate and Event-Free Survival (EFS) were compared between CIG and DIG patients. Results: Overall, no differences in metabolic response classification were observed between PET/ldCT and PET/ceCT. In 13 (26%) patients PET/ceCT identified additional FDG-negative nodal lesions in mesenteric, retroperitoneal and iliac regions. However, in all cases, final DS remained unchanged and the additional results did not modify the following therapeutic decision. Among patients, who obtained complete metabolic response a comparable rate of relapse was registered in DIG 3/13 (23%) and CIG subgroups 5/20 (25%) [p = 0.899]. In all 3 DIG cohort patients who relapsed the recurrent disease involved also, but not exclusively, PET negative lymph nodes detected by ceCT. In overall population metabolic response defined by PET/ldCT predicted EFS (76% vs 35%, p = 0.0013) significantly better than ceCT-Based response assessment (75% vs 53%, p = 0.06). Conclusion: Our study demonstrates a negligible diagnostic and predictive value of ceCT performed in addition to standard 18FDG PET/ldCT for EoT response evaluation in FLs. PET/ldCT should be performed as first-line imaging procedure, also in patients with prevalent abdominal and pelvic involvement, limiting the acquisition of ceCT in selected cases. This tailored approach would contribute to avoid useless radiation exposure and preserve renal function of patients.

This paper has proposed a user-density-based coverage optimization technique for ultra-dense cellular networks. Antenna tilting is a promising coverage optimization technique to be used in 5G networks that significantly improve the signal to interference plus noise ratio (SINR) by choosing the appropriate angle of tilt. In this paper, the cellular coverage has been optimized for scattered user densities/user-hotspots using an adaptive antenna tilting mechanism that steers the beams towards the temporal hot spot in the coverage area. The proposed method has the competence to improve the desired SINR level and coverage area for a group of the user rather than a single user. In this work, a reinforcement learning (RL) algorithm has been implemented to optimize the tilt angle. The performance of the proposed technique has been evaluated in the simulation platform considering a three-sectored multicellular mobile network where the groups of user clusters are distributed randomly. The result confirms the improvement in RSS and SINR value in the group of users having high density with maximum user satisfaction.

Published: June 2021

Now-a-days, with the augmenting accident statistics, Vehicular Ad-hoc Networks (VANET) are turning out to be more popular, which in-turn eradicates accidents in addition to damage to the vehicles together with populace. In a VANET, message can well be transmitted within a pre-stated region to attain safety of a system and also its efficacy. Next, it is challenge to ensure authenticity of messages in such a dynamic environment. Though some researchers have already worked on this, security has not been much focussed. Thus, secured data communication with enhanced security on the VANET environment utilizing the American Standard Code for Information Interchange centred Elliptic Curve Cryptography (ASCII-ECC) is proposed. The proposed scheme allows all vehicles to register with the Trusted Authority (TA) and uses Median-centred K-Means (MKM) to find out the cluster head among all cluster and at the last phase verification is done by TA. The performance of the proposed algorithm ASCII-ECC is analysed and proved that the system renders better performance when it is weighed against the top-notch methods.

Published: June 2021

The frequency and intensity of extreme events especially Heat Waves (HW) are growing all around the world which ultimately poses a serious threat to the health of individuals. To quantify the effects of extreme temperature, appropriate information, and the importance of HW and Heat Index (HI) are carefully discussed for different parts of the world. Varied definitions of the HW and HI formula proposed and used by different countries are carried out systematically continent-wise. Different studies highlighted the number of definitions of HW, however mostly used Steadman’s formulae for the calculation of HI that uses surface air temperature and relative humidity as climatic fields which was developed in the late 1970s. Since then, dramatic changes in climatic conditions have been observed as evident from the ERA5 datasets which need to be addressed. Likewise, the definition of HW, which is modified by the researchers as per the geographic conditions, necessary modification in Steadman’s equation also needs to be done. This study will help the researcher community to understand the importance of HW and HI and think about its modification which further helps in better adaptation and application. Furthermore, it opens the scope to develop an equation based on the present scenario keeping in mind the basics of an index as considered by Steadman.

Background

Metabolic syndrome (MetS) is described as a cluster of cardiometabolic risk factors that can increase the possibility of developing atherosclerotic cardiovascular diseases. According to monastic rules, Thai Buddhist monks are not allowed to cook meals and do exercise. This unique lifestyle generally encompasses low physical activities and may cause several noncommunicable diseases. Thus, in this study, we aimed to examine the prevalence, risk factors, and perception of MetS among Thai Buddhist monks.
Methods

This was a cross-sectional study conducted among Thai Buddhist monks living in Tha Luang District, Lopburi Province, Central Thailand. Study participants completed a questionnaire inquiring about personal and health data, and they also underwent physical examination, including anthropometric measurements, before undergoing biochemical blood tests. MetS was defined based on the National Cholesterol Education Program ATP III (NCEP ATP3) criteria. A qualitative study using in-depth interview was conducted to determine the knowledge and perceptions regarding MetS among Thai Buddhist monks.
Results

In total, 96 Thai Buddhist monks were included in this study. The prevalence of MetS was 28.1%. Participants who had a body mass index of \(\ge\)25 kg/m2 were determined to have a higher risk of developing MetS (OR, 4.5; 95% CI, 1.6–13.3). The in-depth interview revealed that participants’ perceptions were directly associated with their beliefs, experience, and basic healthcare knowledge. A qualitative study identified two primary factors of MetS among Thai Buddhist monks, viz., unhealthy diet and low physical activity.
Conclusions

MetS prevalence in Thai Buddhist monks was moderate compared with that reported by other studies. Medical providers and Buddhist devotees should cooperate in providing health promotion by donating healthy food, conducting annual health checkups, and arranging alternative exercises in a private area that correspond with the monastic rules. Therefore, early screening, treatment, and patient education are the most important factors to manage MetS in Thai Buddhist monks.
