Published: February 2022

Effective learning can originate from classroom as evidenced by effective use of alternative teaching and learning models. Learning should free students from any bondage that would curb excitement and curiosity. The study was conducted on a sample of 461 students who were 12 years of age. Respondents were further categorised on the basis of gender and eventually into experimental and control group. Students in experimental group were given multiple intelligence based worksheets during the intervention programme. The intervention was provided for 12 months and respondents were assessed five times. Later, it was found that owing to the personalized instructions system to teach students in experimental group, there was witnessed significant soar in their cognitive abilities and academic achievement. In contrast, insignificant changes were witnessed among their control group counterparts after the intervention programme.

Published: February 2022

In the era of the industrial revolution 4.0, quantity is not a measure of achieving early childhood outcomes, but how teachers create quality resource based inventions. To form creative and adaptive resources for technology, the teacher must changes the facilities, infrastructure and learning reconstruction. Learning that is prepared to welcome children to face the 21st century is learning based on Science, Technology, Engineering, Art, and Mathematics (STEAM). STEAM is used to consider the interconnected essence of science, technology, engineering, arts and mathematics disciplines and their significance in the long-term academic performance of children. Responding to STEAM-based learning that PAUD teachers need to incorporate in cultivating the creativity of children, it is important to know the degree to which PAUD teachers understand STEAM-based learning. This research discusses  the use of the X-Means clustering algorithm as one of the data mining algorithms in grouping data on the level of comprehensions of PAUD teachers on STEAM-based learning. This research discusses  the use of the X-Means Clustering algorithm as one of the data mining algorithms in grouping data on the level of comprehensions of PAUD teachers on STEAM-based learning.
Christian Values in the Constitutions of Croatia and Slovenia
Authors: Staničić Frane
Published: February 2022

This paper will strive to show that Christian values can be found in almost every constitution in the western world, although explicit invocations of Christian values are quite rare. There are constitutions that use invocatio dei and those that create state churches, but such constitutions represent a minority among constitutions. Croatia and Slovenia make good models for the purpose of this paper as they represent very similar and, at the same time, very different states with regard to the chosen model of state-church relations. The paper will show that, notwithstanding their different constitutional setup of state-church relations, Croatian and Slovene constitutions do not differ much with regard to the presence of Christian values in them.
HEARTWOOD FUNCTIONS AND COMPATIBLE TAPER AND MERCHANTABLE VOLUME SYSTEMS FOR Acacia mangium Willd. IN, TABASCO, MEXICO

Published: February 2022

In the last 20 years in Mexico, 30 % of the plantations supported by the Comisión Nacional Forestal (National Forestry Commission, CONAFOR) were made for timber purposes and established in the states of Tabasco, Veracruz, and Campeche, in Mexico. The economic valuation and management of plantations for these purposes are optimized by estimating the timber volume by type of product. The objectives of this study were to fit three compatible systems of segmented equations of taper and merchantable outside-bark volume; identify functions of taper and cumulative volume of heartwood; and analyze the dendrometric types based on the system developed by Fang et al. (2000) for plantations of clonal trees of Acacia mangium Willd., located in Huimanguillo, Tabasco, Mexico. Ninety-one (91) trees (2, 3, 7 and 8 years old) were cut down and two data groups were formed: 60 trees for fitting, and 31 for validation. The stem volume per section was calculated using the overlapping bolts method. The selection of the models was made according to the classification of four goodness-of-fit statistics. The system developed by Fang et al. (2000) showed reasonable estimates with both groups of measurements. The heartwood volume function overestimated the average percentage of heartwood relative to the inside bark volume in 2-year-old trees. However, it estimated them logically for the other ages: 34.7 % at 3 years, 61.8 % at 7 years, and 67 % at 8 years. The ratio heartwood taper to inside bark taper decreased after reaching 70 % of height.

De separações na cidade a misturas nas praias
Authors: Donegan Lucy , Alves Stela Dias de Sá , Oliveira João Victor Nunes de
Published: February 2022

O caráter marítimo no Brasil é dado pela formação de muitas cidades coloniais à beira-mar e pela natureza pública da orla estabelecida por lei, embora praias possam expressar dinâmicas excludentes. Segregação, dinâmicas urbanas e usos em praias contribuindo para o bem-estar são temas frequentes na literatura sobre o estudo de cidades, mas pouco interligados entre si. Entendendo que a forma do espaço ajuda a unir ou separar pessoas, este artigo investiga a localização na malha urbana, padrões socioespaciais, redes e mobilidades no uso de praias na cidade de João Pessoa, Nordeste brasileiro. Dados demográficos, localizações na malha urbana e dados coletados com frequentadores das praias foram analisados. Resultados indicam que densidades se distribuem mais na cidade acompanhando centralidades urbanas enquanto existe uma clara separação da população mais privilegiada economicamente morando perto do mar. Em contrapartida, essas praias recebem visitantes com mistura de perfis sociais distintos, vindos de diferentes lugares, acentuando um poder de atratividade gerando espaços de potencial encontro entre diferentes na cidade, principalmente nas praias mais integradas na malha urbana. Apesar disso, distância e tempo de deslocamentos custam mais para a população menos privilegiada economicamente visitarem as praias, reforçando desigualdades de acesso ao lazer na praia.

Hannā Diyāb’s “A Sultan of Samarcand”, an Eleventh-Century Old Georgian St. George Legend, and the Construction of an Early Modern Fairy Tale
Authors: B. Bottigheimer Ruth
Published: February 2022

Of the sixteen stories Hannā Diyāb told Antoine Galland to help the elderly scholar complete his 12-volume Mille et Une Nuits (1704–1717) six were omitted. This article examines one of the six discarded tales, “A Sultan of Samarcand”. Rediscovered by Hermann Zotenberg in the late 1880s, translated soon there­after into English by Richard Burton, it was contextualized historically as a product of Eastern Christian narrative tradition by Joseph Szövérffy in 1956 and categorized typologically by him within the Aarne–Thompson tale-type index, as it then existed. Kevin Tuite’s recent research and translation of an eleventh-century Georgian religious legend supports my hypothesis that the Christian St. George legend supplied the story’s core episode. The role of reference works is introduced inter alia to illuminate their role within knowledge creation in general and in the discontinuities of “A Sultan of Samarcand” research in particular.
Legends of a Transylvanian Shrine to the Virgin Mary
Authors: Magyar Zoltán
Published: February 2022

My paper presents a legend tradition related to a well-known Hungarian (Transyl­vanian) place of pilgrimage. Csíksomlyó (Miercurea–Ciuc/Sumuleu) – cur­rently part of Romania ‒ has become a significant place of pilgrimage in the 20th century, similarly to Austria’s Mariazell, Spain’s Santiago de Compostela, the Orthodox Church’s Athos, or the main international shrines to the Virgin Mary (Lourdes, Fatima, Medjugorje). Around this famous pilgrimage place known from the 15th century a thematically rich legend circle has developed over the centuries, typical of Hungarian folklore, which abounds in historical and narrative traditions. At the centre of the group of legends stands the statue of the Virgin Mary, of gothic origin, the miraculous reputation of which is complemented by several historical legend themes (foundational traditions, wars, heroes and saints, crime and punish­ment and other legend motifs inspired by the sacred place). I highlight the most important historical perspectives, the chronological characteristics, the geographical distribution and, above all, the typological diversity of these legends. The legend circle of the shrine of Csíksomlyó in Romania is the totality of the related narrative traditions, that is to say, both the hundred-year-old miracle stories found in written form in different historical sources, and the recent folklore texts collected from oral tradi­tion. Although the time and the circumstances of the records differ significantly, the aim of the narration and the topic of the legends are the same. The legends about the shrine – separated into the given thematic groups – are an organic part of the Catalogue of Hungarian Historical Legends.
Post-UNESCO Effect
Authors: Chakraborty Ayantika
Published: February 2022

Chhau, a traditional masked dance form of West Bengal has been enlisted as ‘UNESCO- Intangible Cultural Heritage of Humanity, 2010’. In 2015, UNESCO along with the MSME of Government of West Bengal developed a ‘Rural Craft Hub’ in Chorida village of Purulia district centring Chhau. Consequently, tourism in the area got international and national patronage. This entire phenomenon encouraged the commercialization of the traditional dance and craft form associated with Chhau as a result of heritagization. Unfortunately, the implication of the heritagization happened in a flawed fashion which eventually led to folklorization and institutionalization while compromising their contextual significance. The paper explores how heritagization ensures the sustainability of intangible tradition like Chhau while leading to folklorization and institutionalization of performance and craft. The paper also documents the history and ritualistic significance of Chhau to draw a lucid comparison between the traditional form and the form which is the result of folklorization. The paper establishes that the Heritagization- Folklorization- Institutionalisation are intertwined with each other in the context of Chhau.  From the interviews of the tourists and locals associated with Chhau, it is evident that the organization concerned with policy making should keep it in mind that an enormous distortion of craft and performance comes along when the target buyers in the market are alien to the traditional context. In such a scenario, the contextual significance of a craft form can be kept intact if the targeted buyers can be made aware of the contextual and functional relevance of the folkloric element that they are consuming in its modernized version.

Published: February 2022

Objective: The aim of this study is to find out the ration of success in the initial probing for the congenital nasolacrimal duct obstruction at age 25th month to 60th month.

Methodology: The study was prospective non-comparative interventional case series. The study included 59 eyes of 47 patients who visited the Ophthalmology HMC Peshawar in 2020. The patients were labelled as CNLDO with history of epiphora and or discharge since birth or first few days of life. The diagnosis was confirmed with evaluation in which it was assessed that there is no other associated adnexal issue like conjunctively congestion.  Examination also included tear meniscus height and resurge test.

Results: In prospective non-comparative interventional case series 52 eyes of 41 patients between the ages of 25 to 60 months with CNLDO were probed. Most of the patients were females i.e. 27. Most of the obstructions were of complex type i.e. 32 while 20 patients were of membranous type. Patients with bilateral CNLDO were 11. Successes ratio of probing in membranous type of obstruction was 90% i.e. 18 eyes got cured while two eyes needed repeated probing. While in case of complex obstruction the success ratio was, 32.2 % i.e. only 10 patients got cured out of 32 patients. Overall success ratio was 54% i.e 28 of 54.

Conclusion: Children presenting with congenial nasolacrimal duct obstruction in older ages should be probed initially.

Published: February 2022

Tujuan penelitian ini untuk menganalisis dampak covid-19 terhadap efektivitas pembelajaran daring di kelas tinggi. Dalam pembelajaran daring kesiapan peserta didik sebagian sudah siap dan sebagian lagi belum siap dikarenakan masih ada peserta didik yang tidak memiliki handphone sebagai media untuk pembelajaran, kuota internet yang tidak memadai dan ada beberapa peserta didik yang tidak peduli sama sekali dengan pembelajaran. Metode yang digunakan dalam penelitian ini adalah deskriptif kualitatif. sampel dalam penelitian ini adalah guru kelas tinggi. Instrumen penelitian ini berupa wawancara dan dokumentasi. Berdasarkan hasil wawancara yang dilakukan menunjukkan bahwa kesiapan guru dalam proses pembelajaran daring selama masa pandemi masih kurang siap, karena guru belum memiliki RPP dalam pembelajaran daring, penggunaan media pembelajaran serta mempersiapkan bahan ajar. Hal tersebut menyebabkan ketidaksinkronan antara guru dan peserta didik, karena guru tidak mempersiapkan RPP dan media pembelajaran dengan baik padahal peserta didik memiliki respon yang baik dalam pembelajaran meskipun mereka tetap tidak memahami materi yang diberikan oleh guru. Respon peserta didik dalam proses pembelajaran daring melalui aplikasi WhatsApp sangat baik. Para peserta didik merespon sangat baik ketika proses pembelajaran berlangsung. Efektivitas pembelajaran daring di kelas tinggi secara keseluruhan masih belum tercapai dengan baik dan masih belum berjalan efektif. Hal tersebut dikarenakan dalam perencanaan pembelajaran daring masih belum dilaksanakan sepenuhnya oleh guru. Perencanaan pembelajaran yang dimaksud seperti pembuatan RPP pembelajaran, penggunaan media pembelajaran serta mempersiapkan bahan ajar.

Authors: Andreas Chrysanthakopoulos Nikolaos , Vryzaki Eleftheria
Published: February 2022

The objective of the current research was to investigate the possible association between Periodontal Disease indices and risk of development Acute Hematopoietic Cancer (Acute Myeloid and Acute Lymphoblastic Leukemia) in a representative Greek adult sample. 174 individuals with Acute Myeloid and Acute Lymphoblastic Leukemia-cases and 174 matched healthy individuals- controls underwent an oral and dental clinical examination and completed a questionnaire. The periodontal condition for cases and controls included Probing Pocket Depth (PPD), Clinical Attachment Loss (CAL) and Gingival Index (GI). Chi-square test and logistic regression models were carried out to assess the possible association. The logistic regression model showed that CAL (p= 0.054) (OR= 2.467, 95% CI= 1.177-2.231), and GI (p= 0.043) (OR = 3.352, 95% CI= 1.285-4.745), were marginally significantly associated with an increased risk of developing Acute Hematopoietic Cancer.
The Potential of Rhamnolipid as Biofungicide against Rigidoporus microporus Isolated from Rubber Tree (Hevea brasiliensis)

Published: February 2022

Rigidoporus microporus is the main causal of white root disease (WRD) in rubber trees (Hevea brasiliensis). The present study investigates the use of rhamnolipid, a biosurfactant produced by Pseudomonas aeruginosa USM-AR2 against R. microporus. In vitro dose-responses towards rhamnolipid were determined on different isolates of R. microporus using the poisoned food technique (PFT). Inhibition of mycelial growth was found to be dose-dependent, with the highest inhibition of 76.74% at 200 ppm (pH 6.29) on SEG isolate. On the contrary, the lowest concentration of rhamnolipid applied at 10 ppm (pH 5.97) had effectively inhibited the growth of RL 19 to 34.36%. AM isolate was assumed to be the most aggressive pathogen due to the lowest inhibition recorded on all rhamnolipid concentrations tested. At the same time, RL 19 was the least aggressive pathogen compared to the other R. microporus isolates. The rhamnolipid concentrations (ppm), which reduced mycelial growth at 50% (EC50), were recorded at 17.82 ppm for AM isolate, 12.52 ppm for RL 26, and 11.80 ppm for RL 19 isolate. This result indicated that rhamnolipid concentrations to inhibit 50% of mycelial growth might vary based on the aggressiveness and the virulence levels of different R. microporus isolates. It was found that pH changes after incorporating rhamnolipid into the PDA were not the main factor affecting the inhibition of R. microporus isolates. It is obvious that rhamnolipid had an inhibitory effect on fungal growth in vitro. It is the first report on rhamnolipid that has been shown to control R. microporus potentially.

Published: February 2022

This study investigated the effects of aerobic training on cardiovascular parameters of diabetic patients attending Murtala Muhammed Specialist Hospital, Kano (MMSHK). The population of this study consisted of 522 diabetic patients attending MMSHK. A sample of 24 type 1 and 24 type 2 diabetic patients were purposively selected and randomly assigned into experimental (n=12) and control (n=12) for both types 1 and type 2 diabetic patients. However only 40 of the subjects completed the study 10 each for type 1 and 2 experimental and control groups. The participants in the experimental groups were engaged in run/walk training three times (on alternate days) weekly for 16 weeks. Both experimental and control groups continued their medications. The control groups were advised to continue with their normal sedentary daily life. The systolic BP, diastolic BP, resting HR and Vo2max of all the subjects were measured before and after the 16 weeks training. Analysis of Covariance (ANCOVA) was used to test the stated hypotheses at 0.05 level of significance. The results revealed a significant reduction in the systolic blood pressure, diastolic blood pressure, resting HR, while the Vo2max increased significantly after the training among the experimental groups both type 1 and type 2 diabetic patients. The implication of the findings is that engaging diabetes patients both type 1 and type 2 in regular aerobic exercises will surely assist in the management and control of the illness due to the prevention of obesity which is known factor of diabetes. Based on the findings of the this study, it is recommended among others, that aerobic exercise (walk/run) should be used as an intervention in the management of both type 1 and 2 diabetes

Fisiología de la resistencia múltiple a los herbicidas glifosato e inhibidores de acetolactato sintasa en amaranthus palmeri
Authors:   , Barco Antoñanzas María , Royuela Hernández Mercedes
Published: February 2022

Este trabajo se plantea en el marco de la necesidad de profundizar en el conocimiento de la fisiología de las plantas resistentes a herbicidas, lo que requiere, no solo identificar y dilucidar las bases moleculares de las resistencias, sino también abordar el plano fisiológico, analizando la respuesta a nivel de metabolismo a la aplicación de estos herbicidas. La utilización de plantas que ya han desarrollado resistencia múltiple a estos herbicidas es una buena herramienta para desarrollar métodos para su detección, aportar claves para su manejo y prevenir su aparición. Además, el establecimiento de la acción herbicida en plantas resistentes permite comprender cómo y por qué son letales estos herbicidas (conocimiento del modo de acción herbicida), ayudando a que su utilización sea más racional y sostenible. Se ha profundizado en la fisiología de una población de A. palmeri con resistencia múltiple (RM) a los herbicidas glifosato y piritiobac (inhibidor de ALS) y en los efectos fisiológicos de estos herbicidas. Para ello, se han caracterizado a nivel molecular los mecanismos de resistencia, y se ha abordado la acción herbicida estudiando la respuesta fisiológica a diferentes niveles tras el tratamiento con glifosato, piritiobac o la mezcla de ambos. Este trabajo proporciona nuevos detalles acerca de la caracterización y de la fisiología de la población RM y aporta información novedosa en cuanto a los efectos fisiológicos provocados en las plantas sensibles y resistentes por los herbicidas IBAR e IBAA. Estos resultados son, potencialmente, de interés práctico para el sector agrícola, por la importancia global de las malas hierbas resistentes a glifosato, herbicida más usado a nivel mundial y a inhibidores de ALS, grupo de herbicidas que incluye un gran número de materias activas. Todo ello, unido al incesante incremento de resistencias múltiples a ambos tipos de herbicidas, hace necesarios los estudios que profundicen en el conocimiento fisiológico de este tipo de resistencias para avanzar hacia un manejo más sostenible y duradero.

Authors: Tena González Méndez Gerardo , Islas Miguel Alejandro Peña , Hernández Pañeda Humberto , Gabilondo Pliego Bernardo , Rodríguez Covarrubias Francisco Tomás
Published: February 2022

Objective:  To describe our experience using polymer clips (Hem-o-lok®) for renal vessel control in laparoscopic living donor nephrectomy (LLDN).

Materials and methods: We conducted a retrospective and descriptive analysis from our database of all minimally invasive living donor nephrectomies (hand-assisted and pure laparoscopic) performed from 2008 to 2020 in our institution. We included patients who underwent LLDN using polymer clips (Hem-o-lok®) for vascular control of renal arteries and veins, and whose clinical records were complete.

Results: 330 LLDN were performed, 183 (55.5%) were hand-assisted nephrectomies and 147 (44.5%) were pure laparoscopic nephrectomies. Mean warm ischemia time (WIT) was 3.98 minutes and median of estimated blood loss (EBL) was 100±140 ml. Four patients (1.2%) required conversion to an open procedure due to vascular injury. 31 complications (9.3%) were registered, of which 23 (6.9%) were non-life-threatening complications. No deaths nor loss of renal grafts were reported.

Limitations: the main drawbacks of this study are its retrospective nature, and that it is limited to only one center.

Originality and value: It is a study that questions the contraindication issued by the FDA for the use of polymer clips for vascular control in LLDN, demonstrating its use is a safe and effective option.

Conclusion

The use of polymer clips, specifically Hem-o-lok®, is a safe method for vascular control of the renal hilum vessels in laparoscopic living donor nephrectomies.

Objectives: To assess the diagnostic accuracy and efficacy of taking history, conducting physical examination, and assessing the radiological characteristics of children suspected of having aspirated foreign bodies (FBs), vis-à-vis tracheobronchoscopy, the gold standard diagnostic tool. An additional objective was to analyze the types and locations of aspirated FBs. Methods: This single-center retrospective cohort study used the archived medical data of consecutive pediatric patients who had presented with suspected tracheobronchial FB aspiration (TFBA) from January 2011 to May 2021. Data regarding clinical presentation, radiological impressions, and intraoperative findings were retrieved from electronic medical records. Results: The subjects comprised 44 children (22 male) with a mean age of 25.4 months (median = 17.5 months). The majority (27; 61.4%) had TFBA. Among the clinical symptoms, choking and coughing had a sensitivity of 93.9% and specificity of 30.0% and 50.0%, respectively in confirming the presence of a FB. Positive physical examination results had a sensitivity of 95.8% and specificity of 63.2%. Radiological results had a sensitivity of 60.0% and specificity of 78.9%. Organic substances constituted 47.7% of the aspirated FBs. Conclusions: Proper clinical assessment with history, physical examination, and imaging can highly predict the presence of TFBAs in children, and help the clinician decide whether bronchoscopy is necessary.

Purpose

Machine learning (ML) and deep learning (DL) can be utilized in radiology to help diagnosis and for predicting management and outcomes based on certain image findings. DL utilizes convolutional neural networks (CNN) and may be used to classify imaging features. The objective of this literature review is to summarize recent publications highlighting the key ways in which ML and DL may be applied in radiology, along with solutions to the problems that this implementation may face.

Material and methods

Twenty-one publications were selected from the primary literature through a PubMed search. The articles included in our review studied a range of applications of artificial intelligence in radiology.

Results

The implementation of artificial intelligence in diagnostic and interventional radiology may improve image analysis, aid in diagnosis, as well as suggest appropriate interventions, clinical predictive modelling, and trainee education. Potential challenges include ethical concerns and the need for appropriate datasets with accurate labels and large sample sizes to train from. Additionally, the training data should be representative of the population to which the future ML platform will be applicable. Finally, machines do not disclose a statistical rationale when expounding on the task purpose, making them difficult to apply in medical imaging.

Conclusions

As radiologists report increased workload, utilization of artificial intelligence may provide improved outcomes in medical imaging by assisting, rather than guiding or replacing, radiologists. Further research should be done on the risks of AI implementation and how to most accurately validate the results.

Introdução: A nogueira-pecã (Carya illinoinensis) pertence à família Juglandaceae, e tem distribuição natural predominante nas regiões temperadas do Hemisfério Norte. O interesse pelos seus frutos tem apresentado um crescimento exponencial no Brasil e outros países, especialmente por seu alto valor nutricional. Além disso, é uma opção de renda para agricultores familiares, devido ao seu potencial de uso em monocultivo, integrada a outros sistemas de cultivo ou em áreas de reserva legal, principalmente no sul do Brasil. Devido à carência de informações genéticas e em decorrência da falta de controle de polinização e de registro de coleta de propágulos nos pomares, os materiais genéticos em cultivo, geralmente, não têm procedência completamente conhecida. Nesse sentido, a caracterização genética a partir de marcadores moleculares pode solucionar esse problema, identificando e distinguindo cultivares e propiciando, as bases para o planejamento de um eventual programa de melhoramento genético da espécie. Objetivos: O presente trabalho objetivou prospectar e validar in silico marcadores moleculares microssatélites plastidiais da nogueira-pecã a partir do genoma do cloroplasto da cultivar Imperial, sequenciado e caracterizado por nosso grupo. Material e métodos: A prospecção de microssatélites e o desenho de iniciadores foi realizada com auxílio do software SSRLocator. A validação in silico dos loci microssatélite prospectados foi realizada com o software SPCR, através da amplificação virtual no genoma plastidial de cinco diferentes cultivares de nogueira pecã (Imperial, Pawnee, Lakota e MX87) disponíveis no GenBank (https://www.ncbi.nlm.nih.gov/genbank/). Resultados: Foram prospectados 12 loci no genoma plastidial da cultivar Imperial (seis dímeros, quatro trímeros e dois tetrâmeros). Após a validação in silico, que avalia se os iniciadores amplificam produtos únicos dentro do tamanho esperado de acordo com os dados provenientes da prospecção, 10 loci foram considerados ótimos e aptos a serem sintetizados para teste. Esses 10 loci apresentaram produtos amplificados in silico em todas as cultivares testadas. Esses marcadores possuem potencial emprego em análises de diversidade genética, na identificação de cultivares e para inciativas visando o melhoramento dessa espécie. Conclusão: Este é o primeiro estudo de desenvolvimento e caracterização de marcadores microssatélites plastidiais espécie-específico para C. illinoinensis com potencial aplicabilidade para gerar informações a respeito da diversidade genética entre as cultivares da espécie.
Up-to-date knowledge of frailty
Authors: Won Chang Won
Published: February 2022

Background: Frailty is a state in which the functional reserves of multiple organs in the body are reduced significantly, making an individual vulnerable to a variety of stressors. As a result, frail individuals are more likely to experience falls, disability, and even mortality. Frailty can be reversible and preventable in many cases with specific modalities, such as exercise, protein-calorie supplementation, vitamin D intake, and reducing polypharmacy. The frailty phenotype and frailty index are the most common methods used to diagnose frailty. In the United Kingdom, primary care physicians must use the electronic frailty index to identify frailty in all patients aged ≥65 years.Current Concepts: The Korean frailty and aging cohort study, a multicenter longitudinal cohort study taking place in Korea, has identified some important factors in the management of frailty. In the middle-old age group (70-79 years old), high-level physical activities were associated with lower incidence of frailty after 2 years, but no effect thereof was observed in the oldest-old group (80-84 years old). Physical activities associated with improvement from frailty after 2 years were high-level activities, but those associated with improvement from prefrailty were at least middle-level activities.Discussion and Conclusion: For the prevention and management of frailty, the age of participants and level of physical activity are important factors to determine the success of interventions. Protein intake of 1.5 g/kg/day is needed to improve not only muscle mass but also gait speed in prefrail or frail elderly patients, especially those with a risk of malnutrition, in a short-term period.

Watermarking is used for the authentication and protection of digital image data. The color image watermarking is a challenging task and may endup to be lengthy. Various transformations based methods are used forenhacingwatermarkrobustnessand to keep itinvisible. Robustness of watermarking methods have been improved using the hybrid DWT-SVD domain. In this paper an improved hybrid transformation method is prpoposed, using the combination of the Hesenberg Decomposition (HD) with the existing DWT-SVD method. The LAB colour space is adopted at the pre-processing stage for the entropy maximization. The entropy analysis is used for justification of the colour space adaptation.Performance of the existing and proposed method is tested on colour images using parametric analysis of normalized correlation (NC),Peak signal to noise ration (PSNR) and SSIM.Efficiency of existing waatermarking methods may detoriate undervarious attacks. The Impact of the various watermark attacks are also evaluated over the extraction quality.

This study investigates the effects of variations in compressor blade profile on the thermo-economic performance of gas turbines. The compressor's thermo-economic performance was determined using data obtained from the power plant. The method used for the analysis was simplifying the compressor, combustion chamber, and turbine into control volumes. Each flow was analyzed based on exergy, economic, and exergy cost principles. As 1 was increased, rotor blade deflection and diffusion were reduced while outlet velocity, stage efficiency, and pressure ratio increased. Pressure ratio increased by up to 20 percent when 1 increased by 10 and decreased by 7.5 percent when  2 increased by 10 . Equipment cost, annualized cost and total capital investment, operation, and maintenance cost increased by 27.68 percent, 27.31 percent, and 22.86 percent as 1 increased by 10 while equipment cost, annualized cost and total capital investment, operation, and maintenance cost increased by 12.44 percent, 12.12 percent, and 12.45 percent as  2 decreased by as much as 10 . Cost of exergy destruction, average unit cost of exergy input and average unit cost of exergy output increase by 2.64 percent, 2.62 percent, and 4.65 percent as 1 increase by 10 . It was recommended that the gas turbine filtration system be improved to suit the harsh environmental conditions of the area to reduce the amount of foulants on compressor blades. This will increase compressor life expectancy and efficiency, save operating and maintenance costs, and increase the reliability of the gas turbine to deliver maximum power. Furthermore, the research findings could serve as a useful reference for designers in selecting a reasonable compressor blade angle.
